ITEM 1.  BUSINESS

OVERVIEW

KeySpan  Corporation  d/b/a KeySpan Energy (the  "Company" or "KeySpan  Energy")
provides a range of energy-related  services through  operations and investments
in selected areas of the energy industry.  The Company is the fourth largest gas
utility in the United  States with  approximately  1.6 million  customers in New
York  City and Long  Island.  The  Company  engages  in  three  core  downstream
businesses:  natural gas  distribution,  electric  services  and  energy-related
services. It also competes in two additional lines of business:  gas exploration
and production and select energy- related investments.

The  Company  was formed to  facilitate  the  combination  (the  "Combination"),
completed  on May 28,  1998,  of  KeySpan  Energy  Corporation  ("KSE")  and its
principal subsidiary,  The Brooklyn Union Gas Company ("Brooklyn Union") and the
non-nuclear  electric generation and natural gas distribution  businesses of the
Long Island Lighting Company  ("LILCO").  To effect the Combination,  all of the
assets  used by LILCO in  connection  with its gas  distribution  business,  its
non-nuclear  electric  generation  business  and the assets  common to its prior
operations (the "Transferred  Assets") were transferred to the Company. The Long
Island Power  Authority  ("LIPA") then acquired all of the common stock of LILCO
for approximately $2.5 billion in cash and the direct or indirect  assumption of
certain  liabilities.  The Company  sold to the former  holders of LILCO  common
stock, shares of the Company's common stock and then acquired KSE by merger with
a wholly-owned subsidiary of the Company in exchange for shares of the Company's
common stock.

The assets of LILCO not transferred to the Company (the "Retained  Assets") were
retained by LIPA and  primarily  consist of LILCO's  electric  transmission  and
distribution  ("T&D") system located on Long Island,  its 18% ownership interest
in Nine Mile Point Nuclear Power  Station,  Unit 2 ("NMP2"),  located in upstate
New York, and certain of LILCO's  regulatory  assets and liabilities  associated
with its electric business.

The Company was organized as a corporation under New York law in 1998.  Brooklyn
Union  was  formed  in  1895  through  the  consolidation  of  several  existing
companies,  the oldest of which  commenced  operations  in 1849,  providing  gas
distribution services throughout the New York City Boroughs of Brooklyn,  Staten
Island  and most of Queens,  New York.  LILCO was  organized  in 1910 to provide
electric and gas services in the Long Island  counties of Nassau and Suffolk and
the Rockaway peninsula in the Borough of Queens, all in New York.

In November 1999, the Company and Eastern Enterprises ("Eastern") announced that
they had signed a  definitive  merger  agreement  under which the  Company  will
acquire  all of the common  stock of  Eastern  for $64.00 per share in cash (the
"K/E Transaction"). Through its subsidiaries, Eastern is the largest gas utility
in New England. It owns and operates Boston Gas Company, Colonial Gas

                                        3

<PAGE>



Company  and  Essex  Gas  Company,  all of which are  natural  gas  distribution
companies operating in Massachusetts.

Boston Gas  Company is a  regulated  utility  that  distributes  natural  gas in
eastern  and  central  Massachusetts,  and also sells  natural gas for resale in
Massachusetts.  Boston Gas has been wholly-  owned by Eastern since 1929 and has
been in business for 177 years,  making it the second  oldest gas company in the
United States. Colonial Gas Company also is a regulated utility that distributes
natural  gas in Cape Cod and  eastern  Massachusetts.  Colonial  Gas has been in
business  for 150 years and was  acquired by eastern in August  1999.  Essex Gas
Company  also is a regulated  utility  that  distributes  natural gas in eastern
Massachusetts.  Essex Gas has been in business for 146 years and was acquired by
Eastern in September 1998.

Eastern also owns  Midland  Enterprises  Inc.,  the second  largest  independent
operator of tow boats and barges on the nations  inland river  system;  Transgas
Inc., an unregulated  energy  trucking  company and ServicEdge  Partners,  Inc.,
which  is  engaged  in  heating,   ventilation  and  air  conditioning  ("HVAC")
installation and maintenance.  At December 31, 1999, Eastern had total assets of
$2.0 billion;  long-term  debt and  preferred  stock of $515.2  million;  common
shareholders equity of $754.6 million; gross revenues of $978.7 million of which
$690.8 million (or approximately  71%) were derived from regulated gas sales and
gas  transportation;  operating earnings of $113.4 million;  and earnings before
extraordinary items of $55.1 million.

In July 1999, Eastern announced that it had entered into an agreement to acquire
EnergyNorth  Inc.,  owner of New Hampshire's  largest  natural gas  distributor,
Energy North Natural Gas, Inc. ("Energy North").  Energy North is located across
the border from, but  contiguous to, areas served by Eastern's gas  distribution
subsidiaries.  In connection with the Company's acquisition of Eastern,  Eastern
has  amended  its  agreement  with  EnergyNorth  Inc. to provide for an all cash
acquisition  of  EnergyNorth  Inc.  shares at a price per share of  $61.13.  The
restructured EnergyNorth Inc. merger is expected to close contemporaneously with
the K/E Transaction  (collectively,  the K/E  Transaction  and the  restructured
EnergyNorth Inc.'s merger are referred to as the "Eastern Transaction").

The Eastern Transaction is conditioned upon, among other things, the approval of
Eastern's  shareholders,  the Securities and Exchange Commission (the "SEC") and
the New Hampshire Public Utility  Commission.  The Company  anticipates that the
transaction  will be  completed in the third or fourth  quarter of 2000,  but is
unable to  determine  when or  whether  all of the  required  approvals  will be
obtained.

The Eastern  transaction has a total value of  approximately  $2.5 billion ($1.7
billion in equity and $0.8 billion in assumed debt and preferred stock).

With the  consummation  of the Eastern  Transaction,  the Company  will become a
registered holding company under the Public Utility Holding Company Act of 1935,
as amended  ("PUHCA").  As such,  the corporate and financial  activities of the
Company and its  subsidiaries,  including the ability of each such entity to pay
dividends, will be subject to regulation of the SEC.

The  increased  size and scope of the combined  organization  should  enable the
combined  company  to:  provide  enhanced,   cost-effective   customer  service;
capitalize on the above-average growth

                                        4

<PAGE>



opportunities for natural gas in the Northeast; and provide additional resources
to the  Company's  unregulated  businesses.  The  combined  company  will  serve
approximately  2.4 million  customers and will be the largest gas distributor in
the Northeast.

As used herein, the "Company" or "KeySpan Energy" refers to KeySpan  Corporation
d/b/a KeySpan  Energy,  Brooklyn  Union and KeySpan Gas East  Corporation  d/b/a
Brooklyn  Union  of Long  Island  ("Brooklyn  Union  of Long  Island"),  its two
principal   gas   distribution   subsidiaries,   and  its  other   subsidiaries,
individually and in the aggregate.  In 1998, the Company changed its fiscal year
end from March 31 to December 31. For financial  reporting  purposes,  financial
statements included, or incorporated by reference,  herein for the period ending
December  31, 1998 are for the nine months then ended and have been  prepared on
the basis that LILCO was deemed the  acquiring  company in the  Combination  for
financial  reporting  purposes.  Unless otherwise  specified,  other information
contained in Part I hereof, for the twelve month periods ended December 31, 1998
and 1997, has been compiled on a combined basis  ("Combined  Company  Basis") to

BUSINESS STRATEGY

The  Company  seeks to become the  premier  energy and  services  company in the
Northeastern United States,  delivering energy,  products and services to people
at their  homes and  businesses.  The Company  engages in three core  downstream
businesses:  natural gas  distribution,  electric  services  and  energy-related
services primarily focused in the Northeast.  It also competes in two additional
lines of business:  gas  exploration  and production  and select  energy-related
investments,  which include  investments  in select  energy  markets or regions,
including the Gulf of Mexico,  Western Canada and Northern Ireland.  The Company
intends  to  grow  through   investments  in  its  core   businesses  and  other
energy-related  activities;  by expanding its gas distribution  business through
the completion of the Eastern  Transaction and the continued  penetration of the
Long Island gas market; by emphasizing  superior customer service; and by taking
advantage of the increasing trend towards  deregulation and competition to offer
an expanded array of energy services to its customers.

Key elements of the Company's business strategy include:

INVESTMENTS IN CORE BUSINESSES AND ENERGY-RELATED  ACTIVITIES.  In recent years,
the Company has made a number of  acquisitions  and  energy-related  investments
designed to enhance its presence in the Northeastern  United States. On June 18,
1999, the Company  acquired the 2,168 megawatt  Ravenswood  electric  generating
plant (the "Ravenswood  Facility") located in Long Island City, Queens, New York
City. The Company's total power generation  capacity,  including its Long Island
generation, now approximates 6,200 megawatts, making it one of the largest power
generators in the region.

As previously  noted, on November 4, 1999, the Company entered into a definitive
merger  agreement  with Eastern to acquire all of its common stock.  The Eastern
Transaction will increase the number of gas distribution  utilities owned by the
Company, to include Boston Gas Company,  Colonial Gas Company, Essex Gas Company
and  EnergyNorth,  resulting in the Company being the largest gas distributor in
the Northeast serving approximately 2.4 million customers.

The Company has also expanded its unregulated energy services  operations in the
Northeast,  through  several  significant  acquisitions,  including  one  of the
largest heating,  ventilation and air conditioning  ("HVAC")  contractors in the
state of Rhode  Island  and a New  Jersey  based HVAC  contractor.  Further,  in
February  2000,  the Company  acquired  additional  companies.  For  information
concerning  these  acquisitions,  see  Note  2  to  the  Consolidated  Financial
Statements, "Business Segment."

Consistent  with the Company's  strategy to make  investments  in certain select
markets outside of the Northeast, the Company made two additional investments in
Western Canada.  In September  1999, the Company  acquired a 37% interest in the
Paddle River gas processing  plant and  associated  gathering  systems  ("Paddle
River");  and in December 1999, the Company  acquired  certain oil properties in
Alberta, Canada.


                                        6

<PAGE>



These  acquisitions  and  energy-related   investments   reflect  the  Company's
commitment  to enhancing its presence as an energy and service  company  focused
primarily  on  the  customer-oriented  segment  of  the  energy  market  in  the
Northeastern United States, with additional  complementary interests in the Gulf
of Mexico and Western Canadian supply basins, as well as Northern Ireland.

EXPANDED GAS  DISTRIBUTION  SERVICES.  The Company has achieved a high degree of
penetration in its Brooklyn Union service  territory,  with approximately 79% of
all one and two family homes currently  using natural gas for space heating.  In
contrast,  only  28% of one and two  family  homes  in  Brooklyn  Union  of Long
Island's  service  territory  currently use natural gas for space  heating.  The
Company believes that there remains a significant  opportunity for increased gas
heating  penetration of the Long Island service  territory and continues to make
capital expenditures to expand its gas distribution  infrastructure in this area
in order to maximize  long-term growth  objectives  while enhancing  shareholder
value. In addition, the Company expects to provide a focused marketing effort in
both service territories, in an attempt to capitalize on the current substantial
price  advantage  that natural gas enjoys over competing fuel oil in residential
and small  commercial  markets in the  metropolitan  New York City - Long Island
area.  Examples of focused marketing  programs include  concentrated  efforts to
convert current non-heating natural gas customers, which would require little or
minimal capital investment; continued targeting of the new construction segments
where  natural gas heating is the  preferred  choice;  and  conversion to gas of
small to medium size commercial businesses and large volume dual-fuel customers.

SUPERIOR CUSTOMER SERVICE.  The Company's utility operations have an outstanding
reputation for customer service and have consistently  received  excellent marks
for   customer   loyalty  and   satisfaction,   as   measured   by   independent
customer-satisfaction  specialists.  In 1999, for the second  consecutive  year,
Brooklyn Union was awarded the Brand Keys Customer  Loyalty Award, as the United
States  energy  provider  that had  achieved  the  highest  level of  success in
anticipating and exceeding customer expectations.

The Company was also recognized for its outstanding commitment to the community.
In 1999,  Brooklyn  Union was  honored by the New York City  Council on the 30th
Anniversary of its Cinderella Program,  which has contributed to the development
of more than 10,000 units of residential  housing as well as the  revitalization
of commercial facilities in Brooklyn, Queens, and Staten Island.

During 1999,  Chairman and Chief Executive Officer,  Robert B. Catell,  received
the American Gas  Association's  Distinguished  Service Award, the association's
highest  honor.  In addition,  in its Century of Power  edition,  Energy Markets
Magazine  honored Chairman and CEO Robert B. Catell as one of the 20th Century's
100 most influential people in gas and electricity. Mr. Catell was cited for his
role in helping to integrate  U.S. and Canadian gas lines to supply  natural gas
in the Northeast through the Iroquois Transmission System.

The Company intends to continue to emphasize superior customer service,  both to
differentiate itself from competitors as markets become increasingly deregulated
and to take  advantage  of selling  opportunities  available  for  complementary
energy-related  services such as appliance repair and energy system installation
and management.


                                        7

EXPANDED SERVICES.  With its strong market presence in the metropolitan New York
City -Long Island area, the Company  believes it is  well-positioned  to provide
customers with an expanded array of  energy-related  services.  In recent years,
the Company  offered gas and electric  marketing  services  throughout New York,
Connecticut, New Jersey, Maryland, Delaware, Pennsylvania and Ohio and appliance
repair, energy management, and related services for residential,  commercial and
industrial  customers  throughout the  metropolitan  New York City - Long Island
area,   as  well  as  in  Rhode   Island.   The  Company   owns  a  fiber  optic
telecommunications  network consisting in excess of 350 miles of fiber optics on
Long Island and, in addition to use in its  operations,  it provides  use of the
network to local carriers. The Company also has become the exclusive provider of
residential fuel cell units  distributed on behalf of a joint venture between GE
MicroGen,  a subsidiary of General  Electric Power Systems and Plug Power in New
York City and Long Island and is the  authorized  service  provider for PC25(TM)
natural-gas-powered   fuel  cells   manufactured  by  International  Fuel  Cells
(IFC)/ONSI(R) Corporation,  subsidiaries of United Technologies, in the New York
metropolitan  area. The Company believes that its investments in the fiber optic
network and fuel cells provide increased growth opportunities for the Company in
new and developing technologies.

INDUSTRY AND COMPETITION

The  electric  and natural  gas sectors of the  regulated  energy  industry  are
undergoing  significant change, as market forces are moving towards replacing or
supplementing  rate regulation as a means of controlling  prices for natural gas
and electricity.  Competition also presents utilities with greater opportunities
to manage the cost of their  natural  gas and  electric  supplies,  and  through
unregulated  affiliates,  to earn  profits on energy  sales and to expand  their
business activities.

Historically, government regulation served both to control prices in the natural
gas and  electric  sectors of the energy  industry and to  substantially  shield
industry  participants  from  competition.  The natural gas sector was segmented
into  three  regulated  parts:  production;   interstate   transportation;   and
franchised  retail sales and local  distribution.  The electric  sector featured
vertically   integrated   utilities  providing   generation,   transmission  and
distribution   services  for  their  franchised   service   territories.   Under
traditional rate  regulation,  utilities were provided the opportunity to earn a
fair, but regulated,  return on invested capital in exchange for a commitment to
serve all  customers  within a franchised  service  territory.  An extensive and
complex regime for the regulation of public utility companies and public utility
holding companies limited natural gas and electric utilities'  opportunities for
geographic expansion and business diversification.

Between  the 1930's and the late  1970's,  federal and state  energy  regulatory
policies remained  relatively  stable, and the structure of the regulated energy
industry  changed little.  However,  after the energy crises in the 1970's,  new
legislation and changes in regulatory  policy set in motion  competitive  forces
that are continuing to reshape the energy industry.

Beginning  in  1978  with  federal   legislation   that  authorized  the  phased
deregulation of wellhead natural gas prices and the establishment of unregulated
electric generation companies, competition has been increasingly introduced into
segments  of the  regulated  energy  industry.  To foster  competition,  federal
regulators  adopted "open access" rules which  required  interstate  natural gas
pipelines and electric transmission systems to "unbundle" wholesale sales, I.E.,
the sale of gas or electricity for resale,  from transportation and transmission
services. Open access also required

                                        8

<PAGE>



interstate gas pipelines and electric utilities,  for the first time, to provide
transportation  and transmission  service on a  non-discriminatory  basis to all
qualified customers.  Recent initiatives also permit market forces,  rather than
regulation, to establish rates charged under short-term contracts for interstate
natural  gas  transportation  and  to  determine  the  allocation  of  increased
electricity  costs that result when electric  transmission  constraints  prevent
lower priced electricity from reaching electric  customers.  By enabling natural
gas producers and electric generators to reach new markets, open access policies
have led to intensified  competition  in wholesale  markets and are altering the
geographic  character  of the  industry.  No longer  typified by isolated  local
companies,  the  natural gas and  electric  sectors in many parts of the country
include a growing  number of firms with  regional,  national  and  international
dimensions.

Parallel  changes in the regulation of retail electric and gas markets are being
implemented  by many state  public  utility  commissions,  including  the Public
Service  Commission  of the  State of New York  ("NYPSC").  On a  state-by-state
basis,  initially  in  the  Northeast,  Mid-Atlantic  and  California,  and  now
spreading to other  regions,  local  franchised  utilities are being required to
separate  their  marketing  and  retail  sales   businesses  from  the  physical
distribution of natural gas and electricity  through pipes and wires. Just as at
the  federal  level,  distribution  services  are  increasingly  required  to be
unbundled  from retail sales,  and made available on a  non-discriminatory  open
access  basis  to  all  qualified  retail  customers.  Retail  natural  gas  and
electricity  marketers  are being  permitted to compete for energy  customers in
what were formerly  exclusive  service  territories  of electric and natural gas
utilities.  However,  natural gas and  electric  utilities  are likely to remain
exclusive providers of unbundled  distribution services through pipes and wires,
and may remain  obligated  to continue to sell  natural  gas or  electricity  to
customers who do not select other suppliers.

In New York  State,  large-volume  retail  customers  have been able to purchase
natural gas supplies directly from non-utility vendors for about 15 years, while
direct sales to  aggregations of small customers have been permitted since 1996.
New York  regulators  have  commenced  initiatives  to  further  enhance  retail
competition in the state. In November 1998, the NYPSC issued a policy  statement
setting forth its vision for furthering  competition in the natural gas industry
and requesting  that each of the gas utility  subsidiaries  file a restructuring
proposal.  In response,  the Company's two gas distribution utility subsidiaries
filed  their  restructuring  proposal  with  the  NYPSC  in  October  1999.  For
additional discussion on gas deregulation, see "NYPSC Regulation."

Similarly,  the NYPSC has been encouraging the development of retail competition
in the electric sector in New York. In the past three years,  electric utilities
have begun to unbundle electric sales from retail  distribution  services,  open
their  franchised  territories  to  competitors,  transfer  control  over  their
transmission systems to an independent system operator, and divest many of their
generating plants. Several New York investor-owned utilities have divested their
non-nuclear  generating  plants,  including  Consolidated  Edison Company of New
York, Inc. ("Con Edison").  In response to a divestiture plan by Con Edison,  in
June 1999, the Company completed the acquisition of the Ravenswood Facility from
Con Edison, as discussed under the heading "The Company - Electric Services."

The  Company's  electric  operations  on Long  Island are  governed by a service
agreement with LIPA, discussed in greater detail below, and FERC. This agreement
generally  provides  for  recovery  of all costs of  production,  operation  and
maintenance, and capital improvements, subject to certain

                                        9

<PAGE>



incentive  provisions.  Also,  since Long Island is considered a "load  pocket,"
I.E., there are insufficient transmission ties to permit a significant amount of
energy to be  transported  into Long  Island,  at this time,  the Company  faces
minimal  competitive  pressures  associated with its electric operations on Long
Island.

As indicated,  the Company also has electric  operations  in New York City.  The
Company currently bids and sells the energy produced by the Ravenswood  Facility
through bidding it into the energy market  operated by the New York  Independent
System Operator ("NYISO"). Further, the Company has a capacity contract with Con
Edison,  which  provides Con Edison with 100% of the  available  capacity of the
Ravenswood  Facility.  The Company anticipates that this contract will expire on
April 30, 2000, at which time the available capacity of the Ravenswood  Facility
will be bid into the  capacity  auction  conducted  by the NYISO.  New York City
local  reliability  rules  currently  require that 80% of the electric  capacity
needs of New York City is to be provided by  "in-city"  generators.  The Company
expects that the current New York City  reliability  rules will remain in effect
through at least 2000.  However,  in the  future,  should  new,  more  efficient
electric  power  plants be built in New York City  and/or the  in-city  capacity
requirements  be  modified,  the capacity  and energy  sales  quantities  of the
Ravenswood  Facility could be adversely  affected.  The Company can not predict,
however,  when or if new power  plants will be built or the nature of future New
York City requirements.

A significant  number of natural gas and electric  utilities have reacted to the
changing  structure of the regulated  energy  industry by entering into business
combinations,  with the goal of reducing  common  costs,  gaining size to better
withstand  competitive  pressures and business cycles,  and attaining  synergies
from the combination of electric and natural gas operations. The Combination and
related  transactions which resulted in the formation of the Company, as well as
the pending Eastern Transaction, illustrate these attributes.

The  transformation  of  the  energy  industry  is an  ongoing  process.  Larger
regional,   national  and  international  companies  are  being  formed  through
acquisitions and mergers. The remaining legal barriers to interregional  natural
gas and electric distribution  companies,  which have been relaxed as the result
of regulatory  decisions,  are the subject of legislative  proposals calling for
repeal or substantial  modifications.  The advent of industry  restructuring has
meant that  regional,  national and  international  companies  are  increasingly
offering  energy  consumers  a wide  array of choices  as to the  supply,  type,
quality and cost of natural gas and electric services as well as other services,
such as telecommunications  and cable. For the Company,  industry  restructuring
means increased  opportunities  to enter new markets and pressures to manage its
costs of doing business.

THE COMPANY

                                GAS DISTRIBUTION

OVERVIEW

The Company sells,  distributes and transports natural gas in two separate,  but
contiguous  service  territories  of  approximately  1,417  square  miles in the
aggregate in the New York City - Long Island metropolitan area. The Company owns
and operates gas distribution, transmission and storage

                                       10

<PAGE>



systems that consist of  approximately  10,146 miles of distribution  pipelines,
576 miles of transmission pipelines and two gas storage facilities.  The Company
serves approximately 1.6 million customers,  of which approximately 1.5 million,
or 94%, are residential.  Gas is offered for sale to residential  customers on a
"firm"  basis,  and to  commercial  and  industrial  customers  on a  "firm"  or
"interruptible" basis. "Firm" service is offered to customers under schedules or
contracts which anticipate no interruptions,  whereas "interruptible" service is
offered to customers under  schedules or contracts  which  anticipate and permit
interruption on short notice,  generally in peak- load seasons. Gas is available
at any time of the year on an  interruptible  basis, if the supply is sufficient
and the  supply  system  is  adequate.  The  Company  also  participates  in the
interstate  markets by releasing pipeline capacity or bundling pipeline capacity
with gas for  "off-system"  sales.  An "off-  system"  customer  consumes gas at
facilities located outside the Company's service  territories,  by connecting to
the Company's facilities or one of its transporter's  facilities,  at a point of
delivery  agreed to by the Company and the customer.  The Company  purchases its
natural gas for sale to its  customers  under  long-term  supply  contracts  and
short-term  spot  contracts.  Such  gas  is  transported  under  both  firm  and
interruptible transportation contracts. In addition, the Company has commitments
for the provision of gas storage capability and peaking supplies.

For the year ended December 31, 1999, gas revenues were $1.753  billion,  or 59%
of the Company's revenues, and gas operating income was $308.4 million.

The gas  operations  of the  Company can be  significantly  affected by seasonal
weather conditions.  Traditionally,  annual revenues are substantially  realized
during  the  heating  season  as a  result  of  higher  sales of gas due to cold
weather.  Accordingly,  operating results historically are most favorable in the
first and fourth calendar quarters.  However,  the Company's gas utility tariffs
contain  weather  normalization  adjustments  that provide for recovery  from or
refund to firm customers of material shortfalls or excesses of firm net revenues
(revenues  less  applicable  gas costs,  if any) during a heating  season due to
variations from normal weather. For additional  discussion,  see "Regulation and
Rate Matters" below.

SALES AND DISTRIBUTION

The Company is the fourth largest gas distribution company in the United States,
providing,  through  its gas  distribution  subsidiaries,  natural gas sales and
transportation  services to customers in the New York City Boroughs of Brooklyn,
Queens and Staten Island and the Long Island counties of Nassau and Suffolk.

   -An MDTH is 10,000 therms  (British  Thermal  Units) and reflects the heating
    content of approximately one million cubic feet of gas. A therm reflects the
    heating content of approximately 100 cubic feet of gas.

The Company sells gas to its firm gas  customers at the Company's  cost for such
gas, plus a charge  designed to recover the costs of  distribution  (including a
return of and a return on invested  capital).  The Company  shares with its firm
gas  customers net revenues  (operating  revenues less the cost of gas purchased
for resale)  from  off-system  sales and, in  addition,  Brooklyn  Union of Long
Island credits its firm gas customers net revenues from on-system  interruptible
gas sales, thereby reducing its rates to these firm customers.

The yearly  variations in firm gas sales and  transportation  quantities is due,
primarily,  to variations in weather between the periods presented.  Measured in
annual  degree  days,  weather was 10% warmer than normal in 1999,  17.5% warmer
than normal in 1998 and 0.2% colder than normal in 1997.  After  normalizing for
weather, firm sales volumes increased by 2.4% in 1999, as compared to 1998. Firm
sales quantities,  after normalizing for weather, were approximately the same in
1998 as compared to 1997.

Transportation   volumes   related   to   electric   generation,   reflect   the
transportation of gas to the Company's electric generating facilities located on
Long  Island.  The  Company  has  been  reporting  these  quantities  since  the
Combination.

The  decrease  in  other  deliveries  in all  periods  is  primarily  due to the
discontinuance  by Brooklyn Union of its off-system sales program in April 1998.
The program was replaced by a management  agreement with Enron Capital and Trade
Resources  Corp. For a further  discussion  and  additional  information on this
agreement, see "Supply and Storage."

For  additional  details  on gas  revenues,  gas  sales  quantities  and  market
saturation,  see Item 7.  Management's  Discussion  and  Analysis  of  Financial
Condition and Results of Operations.

SUPPLY AND STORAGE

The Company has contracts for the purchase of firm long-term  transportation and
storage  services.  The  Company's gas supplies are  purchased  under  long-term
contracts and on the spot market and are  transported  by  interstate  pipelines
from domestic and Canadian  sources.  Storage and peaking supplies are available
to meet system requirements during winter periods.

Regulatory  actions,  economic  factors  and  changes  in  customers  and  their
preferences  continue to reshape the Company's gas operations  markets. A number
of  multi-family,  commercial and  industrial  customers and a growing number of
residential  customers  currently  purchase  their gas supplies from natural gas
marketers and then contract with the Company for local transportation, balancing
and other unbundled services. Since these customers are no longer reliant on the
Company for sales  service,  the quantity of gas that the Company must obtain to
meet remaining sales  customers'  requirements  has been reduced.  This trend is
likely to continue as state regulators  continue to implement  policies designed
to  encourage  customers  to purchase  their gas from  suppliers  other than the
traditional  gas  utilities.  In October 1999, the Company filed a proposal with
the NYPSC  consistent  with the NYPSC's policy  objective of local  distribution
companies  ending  their role as  providers  of merchant  sales  service for the
natural gas commodity. For further information, see "NYPSC Regulation" below.

PEAK-DAY CAPABILITY. The design criteria for the Company's gas system assumes an
average  temperature  of 0(0)F for peak-day  demand.  Under such  criteria,  the
Company  estimates that the  requirements to supply its firm gas customers would
amount to  approximately  1,863 MDTH of gas for a peak-day  during the 1999/2000
winter  season  and that the gas  supplies  available  to the  Company on such a
peak-day amounts to  approximately  2,033 MDTH. For the 2000/2001 winter season,
the  Company   estimates  that  the  peak-day   requirements   would  amount  to
approximately  1,904 MDTH and that the gas supplies  available to the Company on
such a peak day amounts to

                                       13

<PAGE>



approximately  2,033 MDTH.  The  1999/2000  winter  peak-day  throughput  to the
Company's  customers was 1,721 MDTH,  which  occurred on January 17, 2000, at an
average temperature of 9 degrees  Fahrenheit,  representing 85% of the Company's
per day  capability at that time.  The Company had  sufficient  gas available to
meet the requirements of firm gas customers for the 1999/2000 winter season, and
projects  that it also will have  sufficient  gas supply  available to meet such
requirements  for the 2000/2001  winter season.  The Company's firm gas peak-day
capability is summarized in the following table:

PIPELINES.  The Company  purchases  natural gas for sale to its customers  under
contracts  with  suppliers  located in domestic and Canadian  supply  basins and
arranges for its transportation to the Company's facilities under firm long-term
contracts  with  interstate  pipeline  companies.   For  the  1999/2000  winter,
approximately  78% of the  Company's  natural  gas  supply  was  available  from
domestic sources and 22% from Canadian sources.  The Company has available under
firm   contract  750  MDTH  per  day  of   year-round   and  seasonal   pipeline
transportation  capacity  to its  facilities  in the New York City  metropolitan
area.  Major providers of interstate  pipeline  capacity and related services to
the Company include:  Transcontinental  Gas Pipe Line  Corporation  ("Transco"),
Texas  Eastern   Transmission   Corporation  ("Texas  Eastern"),   Iroquois  Gas
Transmission System ("Iroquois"),  Tennessee Gas Pipeline Company ("Tennessee"),
CNG Transmission  Corporation ("CNG") and Texas Gas Transmission Company ("Texas
Gas").

STORAGE.  In order to meet higher winter demand,  the Company also has long-term
contracts  with  Transco,  Texas  Eastern,   Tennessee,  CNG,  Equitrans,  Inc.,
Hattiesburg  First  Reserve and Honeoye  Storage  Corporation,  for  underground
storage  capacity of 58,935 MDTH for the winter  season,  with 779 MDTH per day,
maximum deliverability.

PEAKING  SUPPLIES.  In addition to the pipeline and storage supply,  the Company
supplements  its winter supply with peaking  supplies which are available on the
coldest  days of the  year to  enable  the  Company  to  economically  meet  the
increased requirements of its heating customers.  The Company's peaking supplies
include gas provided by the Company's two liquefied  natural gas ("LNG")  plants
and under peaking supply contracts with four cogeneration facilities/independent
power producers located in its franchise areas. For the 1999/2000 winter season,
the Company has the capability to provide a maximum  peak-day supply of 504 MDTH
on extremely cold days. The LNG plants have a storage  capacity of approximately
2,053 MDTH and  peak-day  throughput  capacity  of 395 MDTH,  or 19% of peak-day
supply.  The Company has  contract  rights  with  Trigen  Services  Corporation,
Brooklyn Navy Cogeneration  Partners, LP, Nissequogue Cogen Partners and the New
York Power Authority to purchase  peaking supplies with a maximum daily capacity
of 110 MDTH and total  available  peaking  supplies  during the winter season of
3,349 MDTH.

GAS SUPPLY MANAGEMENT.  Enron Capital and Trade Resources Corp., a subsidiary of
Enron Corp. ("Enron"), provides gas supply asset management services to Brooklyn
Union.  Under the terms of this agreement,  which has been in effect since April
1, 1998 and expires on March 31, 2000, Enron is responsible for managing certain
aspects of Brooklyn Union's interstate pipeline  transportation,  gas supply and
storage.  Enron is also responsible for satisfying  certain of the Company's gas
supply requirements; however, the Company remains contractually obligated to its
gas suppliers and has not terminated  any of its supply and delivery  contracts.
Pursuant to this  agreement,  Enron paid the Company a fee in 1999, a portion of
which was credited to the  Company's gas  ratepayers,  and obtained the right to
earn   revenues   based  upon  its   management  of  the  Company's  gas  supply
requirements, storage arrangements and off-system capacity.

The  Company  also has an  arrangement  with Coral  Energy  Resources,  L.P.,  a
subsidiary of Shell Oil Company ("Coral"),  whereby Coral assists the Company in
the  origination,   structuring,   valuation  and  execution  of  energy-related
transactions  relating  to  Brooklyn  Union  of Long  Island  and the  Company's
energy-management  services  undertaken  on behalf of LIPA. A sharing  agreement
exists   between  the  gas   ratepayers  and  the  Company  for  off-system  gas
transactions   and  between  the  Company  and  LIPA  for  off-system   electric
transactions.  The Company's  share of the profits on such  transactions is then
shared with Coral.  The Company  also shares in revenues  arising  from  certain
transactions initiated by Coral. This agreement also expires on March 31, 2000.

The Company  currently is in  negotiations  with a large energy  corporation  to
provide  energy supply  management  services to both Brooklyn Union and Brooklyn
Union of Long Island beginning on April 1, 2000.

GAS COSTS. Gas costs for 1999 were $702.0 million and reflect warmer than normal
weather during the year. Variations in gas costs have little impact on operating
results  of the  Company  since its  current  gas rate  structures  include  gas
adjustment  clauses  whereby  variations  between  actual gas costs and gas cost
recoveries  are  deferred  and  subsequently   refunded  to  or  collected  from
customers.

                                ELECTRIC SERVICES

OVERVIEW

The  Company's  electric  services  primarily  consist of (i) the  ownership and
operation of oil and gas fired generating  facilities located on Long Island and
New York and the delivery of the power  generated by the Long Island  facilities
to LIPA;  (ii) the management and operation of LIPA's T&D System;  and (iii) the
management of LIPA's fuel and electric energy purchases and off-system sales.

As more fully described  below,  the Company (i) provides to LIPA all operation,
maintenance and construction  services relating to the Retained Assets through a
Management  Services  Agreement  (the "MSA");  (ii) supplies LIPA with capacity,
energy  conversion and ancillary  services through a Power Supply Agreement (the
"PSA") to allow LIPA to provide electricity to its customers on Long Island; and
(iii) manages all aspects of the fuel supply for the  Generating  Facilities (as
defined  below) as well as all aspects of the  capacity  and energy  owned by or
under contract to LIPA through an Energy Management  Agreement (the "EMA"). Each

On June 18, 1999,  the Company  completed its  acquisition of the 2,168 megawatt
Ravenswood  Facility located in New York City from Con Edison for  approximately
$597 million. As a means of financing this acquisition, the Company entered into
a lease agreement with a special  purpose,  unaffiliated  financing  entity that
acquired  a portion  of the  Ravenswood  Facility  directly  from Con Edison and
leased it to a subsidiary of the Company under a ten year lease. The Company has
guaranteed all payment and performance  obligations of its subsidiary  under the
lease. Another subsidiary of the Company provides all operating, maintenance and
construction  services for the facility.  The lease program was  established  in
order to reduce the  Company's  cash  requirements  by $425  million.  The lease
qualifies  as  an  operating  lease  for  financial   reporting  purposes  while
preserving the Company's  ownership of the facility for federal and state income
tax  purposes.  The  balance of the funds  needed to acquire the  facility  were
provided from cash on hand.  The Company has recorded an asset of  approximately
$200 million, representing its ownership interest in the assets acquired.

The  Company  currently  sells the energy  produced by the  Ravenswood  Facility
through  daily and/or  hourly  bidding into the energy  market  conducted by the
NYISO.  Revenues are recorded when the energy is sold to the NYISO. Further, the
Company has an interim  capacity  contract  with Con Edison  which  provides Con
Edison with 100% of the available capacity of the Ravenswood  Facility under the
capacity  contract.  Capacity  charges  are  billed  to Con  Edison on a monthly
fixed-fee basis. The Company anticipates that this contract will expire on April
30, 2000, at which time the available  capacity of the Ravenswood  Facility will
be bid into an auction process conducted by the NYISO.

For the year ended December 31, 1999,  electric  revenues were $861.6 million or
29% of the Company's revenues and electric operating income was $139.9 million.

GENERATING FACILITY OPERATIONS.

The Company  owns and  operates an  aggregate  of 73 electric  generation  units
throughout Long Island and Queens (the Long Island electric generation units are
referred to as the "Generating  Facilities"),  40 of which can be powered either
by oil or natural gas at the Company's  election.  In recent years,  the Company
has reconfigured  several of its facilities to enable them to burn either oil or
natural  gas,  thus  enabling  the Company to switch  periodically  between fuel
alternatives based upon cost and seasonal environmental requirements.

The following  table  indicates the 1999 summer  capacity of the Company's steam
generation  facilities and internal  combustion  ("IC") Units as reported to the
NYISO:

LIPA AGREEMENTS

POWER SUPPLY AGREEMENT.  The PSA provides for the sale to LIPA by the Company of
all of the capacity and, to the extent LIPA requests, energy from the Generating
Facilities.  Capacity refers to the ability to generate energy and,  pursuant to
NYISO requirements,  must be maintained at specified levels (including reserves)
regardless of the source and amount of energy consumption.  By contrast,  energy
refers to the electricity actually generated for consumption by consumers.  Such
sales  of  capacity  and  energy  from  the  Generating  Facilities  are made at
cost-based wholesale rates regulated by FERC. These rates may be modified in the
future in  accordance  with the terms of the PSA for (i)  agreed  upon labor and
expense  indices  applied to the base year;  (ii) a return of and on the capital
invested in the Generating  Facilities;  and (iii) reasonably  incurred expenses
that are outside the control of the Company.

The PSA provides incentives and penalties for the Company to maintain the output
capability of the Generating Facilities, as measured by annual industry-standard
tests of operating  capability,  and plant  availability  and efficiency.  These
combined  incentives and penalties may total as much as $4 million annually.  In
1999, the Company earned approximately $3.3 million in incentives under the PSA.

The PSA provides LIPA with all of the capacity from the  Generating  Facilities.
However,  LIPA has no obligation to purchase energy conversion services from the
Generating  Facilities and is able to purchase energy on a least-cost basis from
all available  sources  consistent  with existing  transmission  interconnection
limitations of the T&D system.  Under the terms of the PSA, LIPA is obligated to
pay for capacity at rates which reflect a large  percentage of the overall fixed
cost  of  maintaining  and  operating  the  Generating  Facilities.  A  variable
maintenance  charge is imposed for each unit of energy actually generated by the
Generating  Facilities.  The PSA  expires on May 28,  2013 and is  renewable  on
similar terms.  However,  the PSA provides LIPA the option of electing to reduce
or  "ramp-down"  the capacity it purchases  from the Company in accordance  with
agreed-upon  schedules.  In years 7  through  10 of the PSA,  if LIPA  elects to
ramp-down,  the Company is  entitled  to receive  payment for 100 percent of the
present value of the capacity charges otherwise payable

                                       17

<PAGE>



over the remaining term of the PSA. If LIPA  ramps-down the generation  capacity
in years 11 through 15 of the PSA, the  capacity  charges  otherwise  payable by
LIPA will be reduced in  accordance  with a formula  established  in the PSA. If
LIPA exercises its ramp-down  option,  the Company may use any capacity released
by LIPA to bid on new LIPA capacity  requirements  or to bid on LIPA's  capacity
requirements to replace other ramped-down  capacity. If the Company continues to
operate the ramped-down capacity,  the PSA requires it to use reasonable efforts
to market the capacity and energy from the ramped-down capacity and to share any
profits  with LIPA.  Capacity  and energy sold by the Company  from  ramped-down
capacity  must be  transported  over the T&D  system,  and the  Company  will be
required to pay LIPA's standard transmission (and, if applicable,  distribution)
rates  for the  service.  The PSA will be  terminated  in the  event  that  LIPA
exercises  its right to purchase,  at fair market value,  all of the  Generating
Facilities in the twelve- month period beginning on May 28, 2001.

The Company has an  inventory  of sulfur  dioxide  ("SO2")  and  nitrogen  oxide
("NOx")  emission  allowances  that may be sold to third party  purchasers.  The
amount of allowances varies from year to year relative to the level of emissions
from the Generating  Facilities which is greatly dependent on the mix of natural
gas and fuel oil used for generation  and the amount of purchased  power that is
imported onto Long Island. In accordance with the PSA, 33% of emission allowance
sales revenues  attributable to the Generating Facilities is kept by the Company
and the other 67% is credited to LIPA. LIPA also has a right of first refusal on
any  potential   emission   allowance   sales  of  the  Generating   Facilities.
Additionally, the Company is bound by a memorandum of understanding with the New
York State Department of Environmental  Conservation  ("DEC"),  which memorandum
prohibits  the sale of SO2  allowances  into  certain  states and  requires  the
purchaser to be bound by the same restriction, which may affect the market value
of the allowances.

MANAGEMENT  SERVICES  AGREEMENT.  Under the MSA, the Company performs day-to-day
operation and maintenance  services and capital improvements for the T&D system,
including,  among  other  functions,   transmission  and  distribution  facility
operations,  customer service, billing and collection,  meter reading, planning,
engineering,  and  construction,  all in accordance with policies and procedures
adopted  by  LIPA.  The  Company  furnishes  such  services  as  an  independent
contractor  and does not have any  ownership  or  leasehold  interest in the T&D
system.

In exchange for  providing  these  services,  the Company is entitled to earn an
annual management fee of $10 million and may also earn certain incentives, or be
responsible for certain  penalties,  based upon its performance.  The incentives
provide  for  the  Company  to  retain  100% of the  first  $5  million  of cost
reductions and 50% of any additional cost reductions up to 15% of the total cost
budget.  Thereafter, all savings accrue to LIPA. The Company also is required to
absorb any total cost  budget  overruns  up to a maximum of $15  million in each
contract year.

In addition to the foregoing cost-based incentives and penalties, the Company is
eligible for incentives for performance  above certain  threshold  target levels
and subject to  disincentives  for  performance  below certain  other  threshold
levels, with an intermediate band of performance in which neither incentives nor
disincentives  will apply, for system  reliability,  worker safety, and customer
satisfaction.  In 1999, the Company earned $7.2 million in non-cost  performance
incentives.

                                       18

<PAGE>



The MSA shall  continue  in effect  until May 28,  2006.  Thereafter,  LIPA will
commence a competitive  process to solicit a new management  services agreement.
Generally,  the  Company  is  eligible  to submit a bid for such new  management
services agreement.

ENERGY MANAGEMENT  AGREEMENT.  Pursuant to the EMA, the Company (i) procures and
manages fuel supplies for LIPA to fuel the Generating Facilities,  (ii) performs
off-system  capacity and energy  purchases on a least-cost  basis to meet LIPA's
needs, and (iii) makes off-system sales of output from the Generating Facilities
and  other  power  supplies  either  owned or under  contract  to LIPA.  LIPA is
entitled to  two-thirds  of the profit  from any  off-system  electricity  sales
arranged  by the  Company.  The term for the  service  provided  in (i) above is
fifteen years,  and the term for the service provided in (ii) and (iii) above is
eight years.

In exchange for these services, the Company earns an annual fee of $1.5 million,
plus an allowance for certain costs  incurred in performing  services  under the
EMA.  The EMA further  provides  incentives  for control of the cost of fuel and
electricity  purchased  on behalf of LIPA by the Company.  Fuel and  electricity
purchase  prices will be compared to regional price indices and the Company will
receive a payment from LIPA, or be obligated to make a payment to LIPA, for fuel
and/or  purchased  electricity  costs  which are  below or above,  respectively,
specified tolerance bands. The total fuel purchase incentive or disincentive can
be no greater than $5 million annually and the electricity purchase incentive or
disincentive  can be no  greater  than $2 million  annually.  For the year ended
December 31, 1999, the Company earned an aggregate of $5.3 million in incentives
under the EMA.

OTHER RIGHTS. Pursuant to other agreements between LIPA and the Company, certain
future rights have been granted to LIPA.  Subject to certain  conditions,  these
rights  include  the right  for 99 years to lease or  purchase,  at fair  market
value,  parcels  of  land  and to  acquire  unlimited  access  to,  as  well  as
appropriate   easements  at,  the  Generating  Facilities  for  the  purpose  of
constructing  new  electric  generating  facilities  to be  owned by LIPA or its
designee.  Subject to this right  granted to LIPA,  the Company has the right to
sell or lease  property  on or  adjoining  the  Generating  Facilities  to third
parties.  In  addition,  LIPA has the right to acquire a parcel at the  Shoreham
Nuclear Power Station site suitable as the terminus for a potential transmission
cable under Long Island Sound or the potential site of a new gas-fired  combined
cycle generating facility.

The Company owns the common plant (such as  administrative  office buildings and
computer systems) formerly owned by LILCO and recovers LIPA's allocable share of
the  carrying  costs of such plant  through  the MSA.  The Company has agreed to
provide LIPA,  for a period of 99 years,  the right to enter into leases at fair
market value for common plant or  sub-contract  for common services which it may
assign to a  subsequent  manager of the T&D system.  The Company has also agreed
(i)  for a  period  of 99  years  not to  compete  with  LIPA as a  provider  of
transmission or distribution  service on Long Island;  (ii) that LIPA will share
in synergy (I.E.,  efficiency)  savings over a 10-year period  attributed to the
Combination  (estimated  to be  approximately  $1  billion),  which  savings are
incorporated into the cost structure under the LIPA Agreements; and (iii) not to
commence any tax  certiorari  case (until  termination  of the PSA)  challenging
certain property tax assessments relating to the Generating Facilities.

                                       19

GUARANTEES  AND  INDEMNITIES.  The  Company  and LIPA  also  have  entered  into
agreements providing for the guarantee of certain  obligations,  indemnification
against certain  liabilities and allocation of responsibility  and liability for
certain  pre-existing  obligations  and  liabilities.  In  general,  liabilities
associated  with the  Transferred  Assets  have been  assumed by the Company and
liabilities  associated with the Retained  Assets are borne by LIPA,  subject to
certain specified  exceptions.  The Company has assumed all liabilities  arising
from all manufactured gas plant ("MGP") operations of LILCO and its predecessors
and LIPA has assumed certain liabilities  relating to the Generating  Facilities
and all liabilities  traceable to the business and operations  conducted by LIPA
after completion of the Combination.

An agreement also provides for an allocation of liabilities  which relate to the
assets that were common to the  operations of LILCO and/or  shared  services and
are not  traceable  directly to either the business or  operations  conducted by
LIPA or the Company.  LIPA bears 53.6% of the costs associated therewith and the
Company bears the remainder.

In addition,  the Company has assumed environmental  obligations relating to the
Ravenswood  Facility  operations,  but not  including  liabilities  arising from
pre-closing  disposal  of waste at off-site  locations  and any  monetary  fines
arising from Con Edison's pre-closing conduct.  For additional  discussion,  see
"Remediation of Contaminated Property."

                          GAS EXPLORATION & PRODUCTION

The Company is also engaged in the  exploration  and  production of domestic gas
and oil,  through its 64% equity  interest in The  Houston  Exploration  Company
("THEC"),  an  independent  natural gas and oil  company,  and its wholly  owned
subsidiary, KeySpan Exploration and Production, LLC "KeySpan Exploration."

THEC  was  organized  by the  Company  in 1985 to  conduct  natural  gas and oil
exploration and production  activities.  It completed an initial public offering
in 1996 and its shares are currently traded on the New York Stock Exchange under
the symbol "THX." At March 1, 2000,  its  aggregate  market  capitalization  was
approximately $372.3 million (based upon the closing price on the New York Stock
Exchange on that date of $15.5625.  THEC has approximately  23,923,020 shares of
common stock, $.01 par value, outstanding.  More detailed information concerning
the  operations  of THEC is  contained  in the annual,  quarterly  and  periodic
reports filed by THEC with the SEC.

KeySpan   Exploration  was  organized  in  1999,  as  a  Delaware   corporation,
principally  to form a joint  venture  with  THEC.  On March 15,  1999,  KeySpan
Exploration and THEC entered into a joint exploration agreement (the "THEC Joint
Venture")  to explore  for  natural  gas and oil over a term of three  years and
expiring on December 31, 2001, subject to earlier termination,  at the option of
either party, upon proper notice to the other party. THEC contributed all of its
then  undeveloped  offshore  leases  to the  THEC  Joint  Venture,  and  KeySpan
Exploration and Production, LLC acquired a 45% working interest in all prospects
to be drilled under the THEC Joint Venture . THEC retained a 55% interest in the
leases,  and the revenues  generated  from this joint program are shared between
the Company and THEC on a 45% and 55% basis,  respectively.  The Company  commit
approximately $25 million for exploration and development  activities,  and will
reimburse THEC for certain general and  administrative  expenses relating to the
THEC Joint Venture during 2000.

Information  with respect to net proved reserves,  production,  productive wells
and acreage,  undeveloped acreage,  drilling activities,  present activities and
drilling  commitments  is  contained  in Note 16 to the  Consolidated  Financial
Statements, "Supplemental Gas and Oil Disclosures," included herein.

During  1999,  the  Company's  revenues  attributable  to  gas  exploration  and
production  were $150.6 million,  and gas  exploration and production  operating
income was $48.5 million.  Set forth below is certain selected  information with
respect to the Company's gas exploration and production activities:

The Company's interests in exploration and production have achieved  significant
growth in net proved reserves, production and revenues over the past five years.
The Company,  primarily  through its interests in THEC, has increased net proved
reserves  from 150 BCFe at December  31, 1994 to 553 BCFe at December  31, 1999.
During this period,  annual production increased from 22 BCFe in 1994 to 71 BCFe
in 1999. At the close of 1999, daily production  averaged 195 MMcfe per day. The
Company's oil and gas revenues from its interests in exploration  and production
activities have increased from $42 million in 1994 to $150.6 million in 1999.

In September  1999, the Company and THEC jointly  announced  their  intention to
begin a process to review strategic  alternatives for THEC. The process included
an  assessment  of the  role of  THEC  within  the  Company's  strategic  plans,
including the sale of all or a portion of THEC by the Company.  After completing
the review of strategic  alternatives  for THEC,  the Company  concluded that it
would retain its equity interest in THEC.

In November 1998, the Company  extended a $150 million  revolving credit line to
THEC (the "THEC  Facility").  The THEC Facility matures on March 31, 2000 and is
convertible to equity, if borrowings remain outstanding at maturity.  Currently,
there is approximately  $80 million  outstanding and it is anticipated that such
debt will convert into additional common equity on April 1, 2000, increasing the
Company's equity ownership interest in THEC to approximately 70%.

THEC focuses its operations  offshore in the Gulf of Mexico and onshore in South
Texas,  South  Louisiana,  the Arkoma Basin,  East Texas and West Virginia.  The
geographic  focus of its operations  enables it to manage a comparatively  large
asset base with  relatively  few employees and to add and operate  production at
relatively low incremental costs. THEC seeks to balance its offshore and onshore
activities  so  that  the  lower  risk  and  more  stable  production  typically
associated  with onshore  properties  complement the high potential  exploratory
projects in the Gulf of Mexico by balancing risk and reducing volatility. THEC's
business  strategy is to seek to continue to increase  reserves,  production and
cash flow by pursuing internally generated  prospects,  primarily in the Gulf of
Mexico, by conducting  development and exploratory  drilling on its offshore and
onshore properties and by making selective opportune acquisitions.

OFFSHORE  PROPERTIES.  THEC holds  interests  in 86 lease  blocks,  representing
527,279 gross  (286,953  net) acres,  in federal and state waters in the Gulf of
Mexico, of which 28 have current  operations.  THEC operates 22 of these blocks,
accounting for  approximately 79% of THEC's offshore  production.  Over the past
five years,  THEC has drilled 21 successful  exploratory wells and 18 successful
development wells in the Gulf of Mexico,  representing a historical success rate
of  71%.  During  1999,  THEC  drilled  6  successful  exploratory  wells  and 8
successful development wells on its Gulf of Mexico properties.

ONSHORE   PROPERTIES.   THEC  owns  onshore   natural  gas  and  oil  properties
representing  interests  in 1,179  gross (779 net) wells,  approximately  86% of
which THEC is the operator of record,  and 166,450  gross  (116,639  net) acres.
Over the past five years,  THEC has drilled or  participated  in the drilling of
108 successful  development  wells and 9 successful  exploratory  wells onshore,
representing  a  historical  success rate of 80%.  During 1999,  THEC drilled 31
successful  development wells and 2 successful  exploratory wells on its onshore
properties. During the same period, THEC drilled or participated in the drilling
of 6 development wells that were not successful.

                                       22

<PAGE>



Effective  October 1, 1999,  THEC acquired from a private  undisclosed  party an
interest in offshore  producing  properties in the West Cameron 587 field of the
Gulf of Mexico. The newly acquired properties are comprised of 21 BCFe of proved
reserves  and 6 BCFe of  probable  reserves.  The net  purchase  price  of $21.0
million was paid in cash and  financed by  borrowings  under the THEC  Facility.
THEC plans to drill 2 additional wells and install a minimal structure with test
facilities to commence production in 2000.

JOINT VENTURE

During 1999,  THEC  completed  the  drilling of eight  wells,  six of which were
successful.  At December 31,  1999,  two  additional  joint  venture  wells were
drilled,  and  subsequently,  in January and February 2000, three new wells were
spud. During 2000, the THEC Joint Venture plans to drill  approximately  five to
eight offshore  exploratory  wells and to complete the  development and facility
installation of the successful exploratory wells drilled in 1999.

                             ENERGY-RELATED SERVICES

As part of its  business  strategy,  the Company is focusing  on  continuing  to
develop and grow its energy services  through  non-regulated  subsidiaries  that
market and manage natural gas,  electricity,  and consumer products and services
to residential,  commercial and industrial customers, including those within the
Company's   traditional   utility  service   territories.   These  non-regulated
subsidiaries, some of which are currently in the start-up phase, had revenues of
$188.6 million and an operating loss of $3.4 million in 1999.

ENERGY  MARKETING.  The Company buys,  sells and markets gas and electricity and
arranges  for  transportation  and related  services to over  100,000  customers
throughout the  Northeastern  United States,  including those in the gas service
territories of the Company.

ENERGY MANAGEMENT. The Company owns, designs,  constructs and/or operates energy
systems for  commercial  and  industrial  customers and provides  energy-related
services to clients in the  metropolitan New York City - Long Island area and in
New England.

APPLIANCE  SERVICES.  The Company  provides  various  technical and  maintenance
services to customers  throughout the  metropolitan  New York City - Long Island
area,  including the installation,  maintenance and repair of heating equipment,
water heaters, central air conditioners and other appliances.  With over 125,000
service contracts,  the Company is the largest provider of these services in the
State of New York.

TELECOMMUNICATIONS.  The  Company  owns a fiber  optic  network in excess of 350
miles on Long Island. The fiber optic network serves the telecommunication needs
of the Company on Long Island and also serves  several  carriers under short and
long-term agreements.

FUEL CELLS.  The Company has also become the exclusive  provider of  residential
fuel cell units distributed on behalf of a joint venture between GE MicroGen,  a
subsidiary  of GE Power  Systems and Plug Power in New York City and Long Island
and is the authorized  service  provider for PC25(TM)  natural-gas-powered  fuel
cells  manufactured  by  International  Fuel  Cells  (IFC)/ONSI(R)  Corporation,
subsidiaries of United Technologies,  in the metropolitan New York - Long Island
area.

As previously stated, during 1999 and in February 2000, the Company made several
acquisitions to expand its energy services  operations in the  metropolitan  New
York City - Long Island area and in New England.

The Company's  energy-related services operations compete with the marketing and
management operations of both independent and major energy companies in addition
to electric utilities, independent power producers, local distribution companies
and various energy brokers.  As a result of the continuing efforts to deregulate
both  the  natural  gas  and  electric  industries,  the  relative  energy  cost
differences  among  different  forms of energy are expected to be reduced in the
future. Competition is based largely upon pricing,  availability and reliability
of  supply,   technical  and  financial  capabilities,   regional  presence  and
experience.  The Company's  energy-related services subsidiaries are expected to
enable the Company to take advantage of emerging  deregulated energy markets for
both gas and  electricity and the Company  anticipates  that it will continue to
target other

                                       24

acquisitions  which also provide it with  opportunities to expand those services
both within and outside its traditional service territories.

                           ENERGY-RELATED INVESTMENTS

As one of its  complementary  lines of business,  the Company has investments in
energy-related  businesses,  including natural gas pipelines,  midstream natural
gas  processing  and  gathering  facilities  and gas storage  facilities  in the
Northeast region of the United States and in Canada and the United Kingdom.

During 1999, net income from  energy-related  investments was $7.8 million,  and
the Company's  capital  expenditures  in this segment were $49.4 million,  which
represents  the Company's  acquisition  of a 37% interest in Paddle  River,  its
purchase of certain oil  properties  in Canada,  as well as its share of capital
expenditures in the midstream  natural gas assets owned jointly with Gulf Canada
Resources  Limited ("Gulf Canada") and its capital  expenditures  related to its
investment  in the gas  distribution  system in Northern  Ireland,  as discussed
below.

The  Company  owns a 20%  interest  in  Iroquois,  the  partnership  that owns a
374-mile  pipeline  that  currently  transports  946 MDTH of Canadian gas supply
daily from the New  York-Canadian  border to markets in the Northeastern  United
States. The Company is also a shipper on Iroquois and currently transports up to
137 MDTH of gas per day on the pipeline.

The Company owns a 24.5% interest in Phoenix  Natural Gas  ("Phoenix") and a 50%
interest in Premier Transco Pipeline ("Premier") in Northern Ireland. Phoenix is
a gas distribution system serving the City of Belfast,  Northern Ireland,  which
is in its early  stages of  development  pursuant  to an  eight-year  program of
capital  development  and line  extensions.  Premier is an 84-mile  pipeline  to
Northern  Ireland  from  southwest  Scotland  that  has  planned  transportation
capacity of  approximately  300 MDTH of gas supply  daily to markets in Northern
Ireland.

The Company has equity investments in two gas storage facilities in the State of
New York, Honeoye Storage Corporation and Steuben Gas Storage Company.

The Company also has a 50% interest in midstream  natural gas assets  located in
Western Canada owned jointly with Gulf Canada.  The assets include  interests in
14  processing  plants  and  associated   gathering  systems  that  can  process
approximately 1.5 BCFe of natural gas daily, and associated  natural gas liquids
fractionation.  Additionally,  as previously discussed, a 37% interest in Paddle
River was acquired by the Company in September  1999 and in December  1999,  the
Company acquired the Nipisi oil property all in Western Canada.

                           REGULATION AND RATE MATTERS

Gas and electric public utility  companies,  and corporations  which own gas and
electric public utility companies (I.E.,  public utility holding  companies) may
be subject to either or both state and federal  regulation.  In  general,  state
public utility commissions,  such as the NYPSC, regulate the provision of retail
services,  including the distribution and sale of natural gas and electricity to
consumers.  FERC regulates  interstate  natural gas  transportation and electric
transmission,  and has jurisdiction over certain wholesale natural gas sales and
wholesale  electric sales.  Public utility holding  companies,  especially those
with operations in several states,  are regulated by the SEC under PUHCA, and to
some extent by state utility  commissions  through the  regulation of corporate,
financial and affiliate activities of public utilities.

PUBLIC UTILITY  HOLDING COMPANY  REGULATION.  KeySpan Energy is a public utility
holding  company,  although it is currently  exempt from most  regulation  under
PUHCA because of the  predominately  intrastate  character of its public utility
subsidiaries.  The only  provision  of PUHCA  from which  KeySpan  Energy is not
currently  exempt is the  requirement  that any person must  obtain  advance SEC
approval for the  acquisition of 5% or more of voting  securities  issued by any
public utility company or public utility holding company. However, following the
consummation of the Eastern Transaction,  the Company will become a "registered"
holding company under PUHCA. As such, the corporate and financial  activities of
the Company and its  subsidiaries,  including  the ability of each entity to pay
dividends  will be  subject to  regulation  of the SEC.  On March 6,  2000,  the
Company  filed  its  application  with the SEC to  become a  registered  holding
company under PUHCA.

KeySpan  Energy also is subject to indirect  regulation by the NYPSC in the form
of conditions  attached to NYPSC orders authorizing the formation of the Company
and approving the Combination, among other matters. Those conditions address the
manner in which  KeySpan  Energy and its  subsidiaries  interact  with their two
NYPSC-regulated  natural  gas  distribution  subsidiaries,  Brooklyn  Union  and
Brooklyn Union of Long Island.

                                NYPSC REGULATION

NATURAL GAS  UTILITIES.  The NYPSC is the  principal  agency in the State of New
York which  regulates,  as "gas  corporations" - companies that own,  operate or
manage  pipelines and other  facilities  used to distribute or sell natural gas.
The NYPSC regulates the construction,  use and maintenance of intrastate natural
gas facilities, the retail rates, terms and conditions of service offered by gas
corporations, as well as matters relating to the quality, reliability and safety
of service.  The NYPSC also  regulates  the  corporate,  financial and affiliate
activities of gas  corporations.  Both Brooklyn Union and Brooklyn Union of Long
Island are gas corporations subject to the full scope of NYPSC regulation.

Beginning  in the  mid-1980's,  the NYPSC has taken a number of steps to require
the  "unbundling" of natural gas sales and other services from the  distribution
of natural gas through  pipelines  in order to encourage  competition  among gas
sellers and energy service  providers.  In 1985, the NYPSC ordered the major gas
utilities  in the  state  to  offer  transportation  service  for  large  volume
customers who choose to purchase natural gas from other suppliers. Subsequently,
the  NYPSC  required  that  transportation  service  be  made  available  to all
customers beginning on May 1, 1996. Brooklyn

                                       27

<PAGE>



Union and  Brooklyn  Union of Long Island have been  providing a  transportation
service option to all their customers in compliance with that NYPSC requirement.

In April 1997,  the NYPSC  ordered gas utilities to cease  providing  non-safety
related  appliance  repair service by no later than May 1, 2000.  Brooklyn Union
stopped  providing  these  services in April 1998,  and  Brooklyn  Union of Long
Island ceased providing non-emergency appliance repair services on July 1, 1999.
During a  transition  period from  September  22, 1999  through  April 30, 2000,
Brooklyn  Union of Long Island is  implementing  a transition  program to assist
customers in their change to new non-emergency appliance service providers.

In November 1998,  the NYPSC issued a policy  statement  that  anticipated  that
natural gas utilities  would cease sales of gas, and become  transportation-only
providers,  within three to seven  years.  Marketers,  including  those that are
affiliated  with the natural gas utilities,  are permitted to compete for retail
natural  gas sales.  The  NYPSC's  policy  statement  envisions  proceedings  to
restructure  the  operations of natural gas utilities in order to facilitate the
achievement of the objectives articulated in the policy statement.

On October 18, 1999,  Brooklyn Union and Brooklyn Union of Long Island (the "Gas
Companies")  filed a Joint  Restructuring  Proposal  (the  "Proposal")  with the
NYPSC.  The Proposal  outlines how the Gas  Companies  would  restructure  their
operations by  encouraging  all gas consumers to migrate to  transportation-only
service. The Proposal is designed to (i) provide significant impetus towards the
Gas Companies exiting the gas supply business and (ii) present opportunities for
the development of a competitive  unbundled gas supply market for all customers.
Settlement  discussions with the Staff of the NYPSC and other interested parties
have been held regarding the Gas Companies' restructuring proposals. The Company
is unable to predict the outcome of this  matter.  For more  information  on gas
deregulation, see Item 7A, Quantitative and Qualitative Disclosures About Market
Risk.

Brooklyn  Union  currently is operating  under a six-year rate plan that ends on
September 30, 2002.  Brooklyn Union is subject to an earnings sharing  provision
under  which it will be  required  to credit  to  certain  customers  60% of any
utility  earnings up to 100 basis points above  specified  common  equity return
levels (other than any earnings associated with discrete  incentives) and 50% of
any utility earnings in excess of 100 basis points above such threshold  levels.
The threshold levels are13.50% for rate years, September 30 1999, 2000 and 2001;
and 13.25% for rate year 2002.  A safety  and  reliability  incentive  mechanism
provides a maximum 12 basis point  pre-tax  penalty  return on common  equity if
Brooklyn  Union  fails to achieve  certain  safety and  reliability  performance
standards,  and a customer service incentive  performance program with a maximum
40 basis point  pre-tax  penalty  return on equity.  With the  exception  of the
simplification of the customer service performance  standards and the imposition
of the earnings sharing provisions, the Brooklyn Union rate plan approved by the
NYPSC in 1996 remains unchanged.

Brooklyn  Union of Long Island  currently is operating  under a three-year  rate
plan. The rate plan applies to the period December 1, 1997 through  November 30,
2000. Under the plan, if Brooklyn Union of Long Island's earned return on common
equity devoted to its operations  exceeds 11.10%, it must credit back to certain
customers 60% of earnings up to 100 basis points above the 11.10% and 50% of any
earnings in excess of a 12.10% return. Both a customer service and a safety and

                                       28

<PAGE>



reliability  incentive performance program became effective on December 1, 1997,
with  maximum  pre-tax  return on equity  penalties  of 40 and 12 basis  points,
respectively,  if  Brooklyn  Union  of Long  Island  fails  to  achieve  certain
performance standards in these areas. At the conclusion of the Brooklyn Union of
Long Island rate plan on November 30, 2000, Brooklyn Union of Long Island or the
NYPSC on its own  motion,  may  initiate  a  proceeding  to revise the rates and
charges of that company.

As part of the settlement agreement approved by the NYPSC in connection with its
approval of the  Combination  (the  "Stipulation"),  Brooklyn Union and Brooklyn
Union of Long Island are subject to certain affiliate transaction  restrictions,
cost  allocation  and  financial  integrity  conditions  and a code  of  conduct
governing affiliate  relationships.  These restrictions and conditions eliminate
or relax many restrictions previously applicable to Brooklyn Union in such areas
as affiliate  transactions,  use of the name and reputation of Brooklyn Union by
unregulated affiliates, common officers of the Company, the utility subsidiaries
and unregulated subsidiaries, dividend payment restrictions, and the composition
of the Board of Directors of Brooklyn Union.

ELECTRIC  SUPPLIERS.  KeySpan Generation LLC ("KeySpan  Generation") and KeySpan
Ravenswood,  Inc. ("KeySpan  Ravenswood"),  KeySpan Energy's electric generation
subsidiaries,  are not subject to NYPSC rate  regulation  because  their  energy
transactions are made exclusively at wholesale;  however, KeySpan Generation and
KeySpan  Ravenswood  are  subject  to NYPSC  financial,  reliability  and safety
regulation.  As wholesale generators,  KeySpan Generation and KeySpan Ravenswood
qualify  for  "lightened"  regulatory  treatment,   I.E.  certain  discretionary
regulations  are waived and others are applied with less  scrutiny than would be
the case for fully-regulated electric utilities.

                               FEDERAL REGULATION

NATURAL GAS COMPANIES. The FERC has jurisdiction to regulate certain natural gas
sales for resale in interstate  commerce,  the  transportation of natural gas in
interstate commerce, and, unless an exemption applies, companies engaged in such
activities.  The  natural gas  distribution  activities  of  Brooklyn  Union and
Brooklyn Union of Long Island and certain related  intrastate gas transportation
functions  are not  subject to FERC  jurisdiction.  However,  to the extent that
Brooklyn  Union  and  Brooklyn  Union  of Long  Island  sell gas for  resale  in
interstate  commerce,  such sales are subject to FERC jurisdiction and have been
authorized by the FERC.

The Company also owns an approximate  20% interest in Iroquois and 52% and 18.6%
interests  in the Honeoye and  Steuben  gas  storage  facilities,  respectively.
Iroquois,  Honeoye and Steuben  are fully  regulated  by the FERC as natural gas
companies.

ELECTRIC SUPPLIERS.  The FERC regulates the sale of electricity at wholesale and
the  transmission  of  electricity  in  interstate  commerce  as well as certain
corporate  and  financial  activities  of  companies  that are  engaged  in such
activities.

The  Generating  Facilities  and the  Ravenswood  Facility  are  subject to FERC
regulation  based  on  their  wholesale  energy   transactions.   LIPA,  KeySpan
Generation,  and the Staff of FERC  stipulated  to  setting  rates  designed  to
recover  $300.5  million in the first year with  agreed-upon  adjustments to set
rates for the remainder of the five-year rate period.  The only party opposed to
this stipulation is the

                                       29

<PAGE>



County of Suffolk. Parties submitted initial briefs to a FERC Administrative Law
Judge ("ALJ") on December 8, 1998 and reply briefs on January 15, 1999. On April
15, 1999, the presiding ALJ issued an Initial Decision which ordered, subject to
review of the Commission on exceptions or on its own motion,  that the rates and
terms  contained  in the PSA, as modified by the June 30, 1998  Stipulation  and
Agreement, are just and reasonable.  On June 17, 1999, this initial decision was
made a final  order  of the  FERC.  The  FERC  retains  the  ability  in  future
proceedings,  either on its own motion or upon a complaint  filed with the FERC,
to modify KeySpan  Generation's  rates,  either upward or downward,  if the FERC
finds that the public interest requires it to do so.

KeySpan  Ravenswood's  rates  are based on its  market  based  rate  application
approved by FERC.  The rates that KeySpan  Ravenswood  may charge are subject to
mitigation  measures  due to market power  concerns of the FERC.  As is the case
with KeySpan  Generation,  the FERC  retains the ability in future  proceedings,
either on its own  motion or upon a  complaint  filed  with the FERC,  to modify
KeySpan  Ravenswood's  rates,  either upward or downward,  if the FERC concludes
that it is in the public interest to do so.

                          REGULATION IN OTHER COUNTRIES

The Company's  operations in Northern  Ireland,  conducted  through  Premier and
Phoenix, are subject to licensing by the Northern Ireland Department of Economic
Development  and  regulation by the U.K.  Department of Trade and Industry (with
respect to the subsea and  on-land  portions of the  Premier  pipeline)  and the
Northern Ireland Director General,  Office for the Regulation of Electricity and
Gas (with respect to the Northern  Ireland  portion of the Premier  pipeline and
Phoenix's  operations  generally).  The licenses  establish  mechanisms  for the
establishment of rates for the conveyance and transportation of natural gas, and
generally  may not be revoked  except  upon long- term  notice.  Charges for the
supply of gas by Phoenix are largely  unregulated unless a determination is made
of an absence of competition.

The Company's assets in Canada are subject to regulation by Canadian  provincial
authorities.   Such  regulatory   authorities  license  the  operations  of  the
facilities and regulate safety matters and certain  changes in such  facilities'
operations.


                              ENVIRONMENTAL MATTERS

OVERVIEW

The Company's ordinary business operations subject it to various federal,  state
and local laws, rules and regulations  dealing with the  environment,  including
air, water, and hazardous  waste,  and its business  operations are regulated by
various federal,  regional,  state and local  authorities,  including the United
States  Environmental  Protection Agency (the "EPA"), the DEC, the New York City
Department  of  Environmental  Protection  (NYC DEP) and the Nassau and  Suffolk
County Departments of Health. These requirements govern both the normal, ongoing
operations  of the  Company  and  the  remediation  of  contaminated  properties
historically used in utility operations. Potential liability associated with the
Company's historical  operations may be imposed without regard to fault, even if
the activities were lawful at the time they occurred.

                                       30

<PAGE>



Ensuring  continuing  compliance  with  environmental  requirements  may require
significant  expenditures  for capital  improvements  or  modifications  in some
areas.  Total capital  expenditures for  environmental  improvements and related
studies, for other than MGP matters,  amounted to approximately $1.7 million for
the year ended December 31, 1999, and are expected to be in the $1 to $2 million
range for the year ending December 31, 2000.

Except as set forth below,  no material  proceedings  relating to  environmental
matters  have  been  commenced  or,  to  the  knowledge  of  the  Company,   are
contemplated by any federal,  state or local agency against the Company, and the
Company is not a defendant in any material litigation with respect to any matter
relating to the  protection of the  environment.  The Company  believes that its
operations  are in  substantial  compliance  with  environmental  laws  and that
requirements  imposed  by  environmental  laws are not likely to have a material
adverse  impact  upon the  Company.  The  Company  believes  that all  prudently
incurred  costs not  recoverable  through  insurance  or some  other  means with
respect to  environmental  requirements  will be recoverable from its customers.
The Company also is pursuing claims against  insurance  carriers and potentially
responsible parties which seek the recovery of certain costs associated with the
investigation and remediation of contaminated properties.

AIR. Federal, state and local laws currently regulate a variety of air emissions
from new and existing electric  generating  plants,  including SO2, NOx, opacity
and particulate  matter and, in the future,  may also regulate emissions of fine
particulate matter,  hazardous air pollutants,  and carbon dioxide.  The Company
has  submitted   timely   applications   for  permits  in  accordance  with  the
requirements  of Title V of the 1990  amendments  to the  Federal  Clean Air Act
("CAA").  Final  permits  have been  issued  for all of the  Company's  electric
generating  facilities  with  the  exception  of the Far  Rockaway  and  KeySpan
Ravenswood  facilities,  which are  pending.  The  permits  allow the  Company's
electric  generating  plants to  continue  to  operate  without  any  additional
significant expenditures, except as described below.

The  Company's  generating  facilities  are  located  within a CAA severe  ozone
non-attainment  area,  and are subject to the Phase I, II, and III NOx reduction
requirements  established  under the  Ozone  Transportation  Commission  ("OTC")
memorandum of  understanding.  The Company's  investments  in boiler  combustion
modifications and the use of natural gas firing at its steam electric generating
stations has enabled the Company to achieve the NOx emission reductions required
under Phase I and II in a  cost-effective  manner.  In  addition,  software  and
equipment upgrades of approximately $1 million for continuous emissions monitors
("CEM") may be required in 2000 to meet EPA  requirements  for the NOx allowance
tracking/trading  program and certain  other  regulatory  changes  affecting the
operation  of CEM  systems.  The  Company  currently  estimates  that  it may be
required  to spend  between  $5  million  and $25  million  by the year 2003 for
additional  pollution  control  equipment  to  achieve  the  OTC  Phase  III NOx
reduction  requirements and/or new requirements  imposed under the EPA NOx state
implementation  plan,  depending on the actual level of NOx emission  reductions
which are required when pending  regulations are implemented by the State of New
York.

WATER.  The Company  possesses  permits for its generating units which authorize
discharges  from  cooling  water  circulating  systems  and  chemical  treatment
systems. These permits are renewed from

                                       31

<PAGE>



time to time, as required by  regulation.  The Company does not foresee any new,
material obligations arising from these permit renewals.

On behalf of LIPA, the Company  provides  management and operations  support for
the LIPA- Connecticut Light and Power Company electric transmission cable system
located  under the Long  Island  Sound  (the  "Sound  Cable").  The  Connecticut
Department  of  Environmental  Protection  and the DEC  separately  have  issued
Administrative Consent Orders ("ACOs") in connection with releases of insulating
fluid from the Sound  Cable.  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 and are recoverable
from LIPA under the MSA.

                      REMEDIATION OF CONTAMINATED PROPERTY

SUPERFUND  SITES.  Federal and New York State  Superfund laws impose  liability,
regardless  of  fault,  upon  generators  of  hazardous   substances  for  costs
associated with remediating contaminated property. In the course of its business
operations,  the Company  generates  materials  which are subject to these laws.
From time to time, the Company has received  notices under these laws concerning
possible claims with respect to sites at which hazardous substances generated by
the Company and other potentially  responsible  parties ("PRPs")  allegedly were
disposed.

The DEC has notified the Company,  pursuant to the State Superfund program, that
the Company 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 the Company currently is unable
to  estimate  its  share,  if any,  of the costs  required  to  investigate  and
remediate this site.

MANUFACTURED  GAS PLANT SITES.  The Company has identified  twenty-six MGP sites
which were historically owned or operated by Brooklyn Union or Brooklyn Union of
Long Island (or such companies' predecessors). Operations at these plants in the
late  1800's and early  1900's may have  resulted  in the  release of  hazardous
substances.  These  former  sites,  some of  which  are no  longer  owned by the
Company, have been identified to both the DEC for inclusion on appropriate waste
site  inventories  and the PSC. The  currently-known  conditions  of fourteen of
these former MGP sites,  their  period and  magnitude  of  operation,  generally
observed cleanup  requirements  and costs in the industry,  current land use and
ownership,  and possible reuse have been considered in establishing  contingency
reserves that are discussed below.

In  1995,  Brooklyn  Union  executed  an ACO with the DEC  which  addressed  the
investigation  and  remediation  of a site in Coney Island,  Brooklyn.  In 1998,
Brooklyn  Union  executed an ACO for the  investigation  and  remediation of the
Clifton MGP site in Staten  Island.  At the  initiative  of DEC, the City of New
York and the  Company  are in  negotiations  on a cost  sharing  arrangement  to
conduct  investigations in 2000 at the Citizen's MGP site in Brooklyn,  which is
now  primarily  owned by the City,  but was  formerly  owned and  operated  by a
Brooklyn  Union  predecessor.  The DEC notified the Company in 1998 that the Sag
Harbor and Rockaway Park MGP sites owned by Brooklyn  Union of Long Island would
require remediation under the State's Superfund program. Accordingly, the

                                       32

<PAGE>



Sag  Harbor  and  Rockaway  Park  sites;  as well as the Bay  Shore,  Glen Cove,
Halesite and Hempstead MGP sites;  are the subject of two separate  ACOs,  which
the Company  executed  with the DEC in March and September  1999,  respectively.
Field investigations and, in some cases, interim remedial measures, are underway
or  scheduled to occur at each of these sites under the  supervision  of the DEC
and the New York State Department of Health.

The  Company  was  also  requested  by  the  DEC  to  perform  preliminary  site
assessments at the Patchogue,  Babylon, Far Rockaway,  Garden City and Hempstead
(Clinton  St.) MGP sites,  each of which were formerly  owned by LILCO,  under a
separate ACO entered into in September 1999.  Initial studies based on existing,
available  documentation  have been completed for each such site and the DEC has
requested  that the Company  collect  additional  samples at each of the subject
properties.

With the  exception  of the Coney  Island site,  which will be  redeveloped  for
commercial or industrial use, the final end uses for the sites  identified above
and, therefore,  acceptable remediation goals have not yet been determined.  The
Company is required to prepare a feasibility  study for the  remediation of each
such site,  based on cleanup levels derived from risk analyses  associated  with
the  proposed or  anticipated  future use of the  properties.  The  schedule for
completing  this  phase of the work  under  the  ACOs for the  identified  sites
discussed above extends through 2001.

Thus, thirteen sites identified above are currently the subject of ACOs with the
DEC and one is subject to the  negotiation  of such an agreement.  The Company's
remaining  MGP  sites  may  not  become  subject  to  ACOs  in the  future,  and
accordingly no liability has been accrued for these sites. It is possible, based
on  future  investigation,  that  the  Company  may  be  required  to  undertake
investigation  and potential  remediation  efforts at these,  or other currently
unknown former MGP sites.  However, the Company is currently unable to determine
whether or to what extent such additional costs may be incurred.

The  Company  believes  that  in  the  aggregate,   the  accrued  liability  for
investigation  and remediation of the MGP sites  identified above are reasonable
estimates  of  likely  cost  within a range of  reasonable,  foreseeable  costs.
Accordingly,  the  Company  presently  estimates  the cost of its  MGP-  related
environmental  cleanup  activities  will be $123 million;  which amount has been
accrued  by  the  Company  as  its  current  best   estimate  of  its  aggregate
environmental  liability  for known sites.  As previously  indicated,  the total
MGP-related  costs  may be  substantially  higher,  depending  upon  remediation
experience,  selected end use for each site, and actual environmental conditions
encountered.

The NYPSC  approved  rate plans for Brooklyn  Union and  Brooklyn  Union of Long
Island provide for the recovery of such investigation and remediation costs. The
Brooklyn Union rate plan provides, among other things, that if the total cost of
investigation and remediation  varies from that which is specifically  estimated
for a site under  investigation  and/or  remediation,  then Brooklyn  Union will
retain or absorb up to 10% of the  variation.  The Brooklyn Union of Long Island
rate plan also provides for the recovery of investigation  and remediation costs
but with no consideration of the difference  between estimated and actual costs.
Under  prior  rate  orders,  Brooklyn  Union has  offset  certain  moneys due to
ratepayers against its estimated  environmental  cleanup costs for MGP sites. At
December  31,  1999,  the Company  has  reflected  a  regulatory  asset of $95.6
million.

Expenditures  incurred  to date  by the  Company  with  respect  to  MGP-related
activities total $15.9 million.

Periodic  discussions by the Company with  insurance  carriers and third parties
for  reimbursement  of some portion of MGP site  investigation  and  remediation
costs continue.  In December 1996,  LILCO filed a complaint in the United States
District Court for the Southern District of New York against fourteen  insurance
companies  that issued general  comprehensive  liability  policies to LILCO.  In
January 1998, LILCO commenced a similar action against the same, and additional,
insurance  companies  in New York State  Supreme  Court,  and the federal  court
action subsequently was dismissed.  The state court action is being conducted by
the  Company on behalf of  Brooklyn  Union of Long  Island.  The outcome of this
proceeding  cannot  yet  be  determined.  In  addition,  Brooklyn  Union  is  in
discussions  with  insurance  carriers  regarding  the  possible  resolution  of
coverage claims related to its MGP site investigation and remediation activities
without  litigation.  The  Company is not able to predict  the  outcome of these
discussions.

RAVENSWOOD  FACILITY.  In  connection  with  the  Company's  acquisition  of the
Ravenswood  Facility,  the  Company  assumed  all  of  Con  Edison's  historical
contingent environmental  obligations relating to facility operations other than
liabilities arising from pre-closing disposal of waste at off-site locations and
any  monetary  fines  arising  from  Con  Edison's  pre-closing  conduct.  These
environmental  exposures  are  generally  divided  between  (i)  future  capital
expenditures, in the nature of property and leasehold improvements, necessary to
address  compliance  obligations and (ii)  expenditures  to investigate  and, as
necessary,  remediate certain on-site  contamination which may or may not result
in leasehold improvements.

Presently,  there are four ACOs issued to Con Edison by the DEC. The Company has
contractually  agreed  to  assume  Con  Edison's  remaining  obligations  at the
Ravenswood  Facility  under  these ACOs.  Generally,  the  Company's  derivative
obligations  are expected to include  investigation  and  remediation of certain
petroleum releases,  inspection and any necessary  corrective action for certain
aboveground storage tanks and underground piping, potential upgrades to existing
cooling water intake structures,  and implementation of an air emissions opacity
reduction program. The Company is currently  negotiating a consolidated ACO with
the DEC that will clarify the scope and timing of these activities.

The  Company has  identified  certain  capital  expenditures  for  environmental
compliance  purposes at the Ravenswood  Facility that are  reasonably  likely to
occur. To address an anticipated shortfall of NOx emissions allowances beginning
in May 2003,  the Company may incur capital costs for  additional  air pollution
control equipment.  Alternatively,  the Company may elect to purchase additional
NOx allowances.  The Company may be required to upgrade the Ravenswood  Facility
cooling  intake  structures  in  order to meet  the  best  available  technology
requirements of the Federal Clean Water Act. The extent and cost of any upgrades
are  uncertain and will depend upon the analysis and  interpretation  of certain
studies submitted by the Company to the DEC and subsequently agreed upon between
the DEC and the Company.

Pursuant to its  derivative  ACO  obligations,  the Company  will  complete  the
investigation and remediation of certain petroleum and other hazardous  material
releases at the Ravenswood Facility, as necessary. The Company will also address
similar releases not covered by the ACO's. The

                                       34

Ravenswood  Facility is located on a former MGP site. The Company has no current
obligation to investigate or remediate the property for contamination  resulting
from historical MGP operations,  although there may be a need to perform certain
site  remediation as part of an overall  improvement of property  related to the
installation  of  new  generation  capacity.   Based  on  information  currently
available for environmental contingencies related to the Ravenswood acquisition,
the Company has accrued $5 million as the minimum liability to be incurred.

Information  with  respect  to the  Company's  material  properties  used in the
conduct of its business is set forth in, or incorporated by reference in, Item 1
hereof.  Except where otherwise specified,  all such properties are owned or, in
the case of certain  rights of way used in the  conduct of its gas  distribution
business,  held pursuant to municipal  consents,  easements or long-term leases,
and in the case of oil and gas properties,  held under long-term mineral leases.
In addition to the  information  set forth  therein with  respect to  properties
utilized  by each  business  segment,  the  Company  owns or leases a variety of
office space used for administrative  operations of the Company.  In the case of
leased  office  space,  the Company  anticipates  no  significant  difficulty in
leasing  alternative  space at reasonable  rates in the event of the expiration,
cancellation  or  termination  of a  lease  relating  to  the  Company's  leased
properties.


ITEM 3.  LEGAL PROCEEDINGS

From time to time, the Company is subject to various legal  proceedings  arising
out of the  ordinary  course of its  business.  Except as described  below,  the
Company does not consider any of such proceedings to be material to its business
or likely to result in a material adverse effect on its results of operations or
financial condition.

In October 1998,  the County of Suffolk and the Towns of Huntington  and Babylon
commenced  an action  against  LIPA,  the  Company,  the NYPSC and others in the
United  States  District  Court  for  the  Eastern  District  of New  York  (the
"Huntington Lawsuit").  The Huntington Lawsuit alleges, among other things, that
LILCO  ratepayers  (i) have a property  right to receive or share in the alleged
capital gain that resulted from the transaction with LIPA (which gain is alleged
to be at least $1  billion);  and (ii)  that  LILCO  was  required  to refund to
ratepayers the amount of a Shoreham-related  deferred tax reserve (alleged to be
at least $800 million)  carried on the books of LILCO at the consummation of the
LIPA  transaction.  In December  1998,  and again in June 1999,  the  plaintiffs
amended their complaint.  The amended complaint contains allegations relating to
certain  payments LILCO had determined  were payable in connection with the LIPA
Transaction  and KeySpan  Acquisition  to LILCO's  Chairman  and certain  former
officers and adds the  recipients of the payments as  defendants.  In June 1999,
the Company was served with the second  amended  complaint.  On August 23, 1999,
the Company filed a motion to dismiss the second amended complaint.  Pursuant to
an  agreement  among the  parties,  the  Company's  motion to  dismiss  is being
converted to a summary  judgement  motion. At this time the Company is unable to
determine the outcome of this ongoing proceeding.

A class settlement,  which became effective in June 1989 (COUNTY OF SUFFOLK,  ET
AL., V. LONG ISLAND LIGHTING COMPANY,  ET AL.), resolved a civil lawsuit against
LILCO brought under the federal Racketeer  Influenced and Corrupt  Organizations
Act, alleging that LILCO made inadequate disclosures before the NYPSC concerning
the  construction  and completion of nuclear  generating  facilities.  The class
settlement  provided  electric  customers with rate reductions of $390.0 million
that were being reflected as adjustments to their monthly  electric bills over a
ten-year period which began on June 1, 1990. The class settlement  obligation of
approximately $20 million at December 31, 1999 reflects the present value of the
remaining  reductions  to be  refunded  to  customers.  As a result  of the LIPA
Transaction,  LIPA will provide the remaining balance to its electric  customers
as an  adjustment  to their monthly  electric  bills.  The Company will then, in
turn,  reimburse  LIPA on a monthly basis for such  reductions on the customer's
monthly bill. The Company remains ultimately obligated for amounts due under the
class  settlement.  In November  1999,  class  counsel for the LILCO  ratepayers
served a motion, in the United States District Court for the Eastern District of
New York, seeking an order directing the Company to pay $42 million, in addition
to the amounts  remaining to be paid under the class  settlement.  Class counsel
contends that the required rate  reductions  should have been exclusive of gross
receipts  taxes.  The Company  filed its  opposition  in January  2000 and class
counsel  filed their reply papers in February  2000. In their  February  papers,
class counsel revised their demand to seek an order directing the Company to pay
approximately $22 million,  plus interest,  in addition to the amounts remaining
to be paid under the class  settlement.  The Company  filed its rebuttal  papers
March 1, 2000 and oral  argument  was held March 6, 2000.  On March 9, 2000,  an
order was issued by the court granting class counsel's motion. The Company is in
the process of evaluating  the order and,  accordingly,  is currently  unable to
determine the ultimate  outcome of the  proceeding or what effect,  if any, such
outcome will have on its financial condition or results of operations.

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
(BECHER,  ET AL., V. LONG ISLAND LIGHTING COMPANY, ET AL.). 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.  The plaintiffs are now seeking,  among other things, to have
these reduced benefits restored to their pension accounts. In November 1997, the
Company filed a motion for partial summary  judgment with the District Court. On
April 28, 1998, the Court denied the Company's  motion and permitted the Company
to file a further motion for partial summary judgment on additional  grounds. On
January 27, 1999,  the Company  entered a stipulation  of  settlement  which was
filed with the Court  pursuant to which the Company  will pay  approximately  $8
million, a substantial  portion of which is recoverable from LIPA. On August 13,
1999,  the Court  approved the  stipulation  of  settlement  and  dismissed  the
litigation with prejudice.

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

KeySpan  Corporation,  d/b/a KeySpan Energy (the "Company" or "KeySpan Energy"),
is a holding  company  operating two utilities  that  distribute  natural gas to
approximately 1.6 million customers in New York City and on Long Island,  making
it the fourth  largest  gas-distribution  company in the  United  States.  Other
KeySpan Energy companies market a portfolio of gas-marketing and energy- related
services in the  Northeast,  own and operate  electric-generation  plants in New
York City and on Long Island,  and provide  operating  and customer  services to
approximately 1.1 million electric  customers of the Long Island Power Authority
("LIPA").  The Company's other energy  activities  include:  gas exploration and
production, primarily through The Houston Exploration Company ("THEC"); domestic
pipelines and storage; and international activities, including gas processing in
Canada, and gas pipelines and local distribution in Northern Ireland.  (See Note
2 to the Consolidated  Financial Statements,  "Business Segments" for additional
information on each operating segment.)

The Company was formed on May 28, 1998 as a result of a transaction between Long
Island  Lighting  Company  ("LILCO")  and  LIPA  (the  "LIPA  Transaction")  and
following  the  acquisition  (the  "KeySpan   Acquisition")  of  KeySpan  Energy
Corporation  ("KSE").  (See Note 14 to the  Consolidated  Financial  Statements,
"Sale of LILCO Assets, Acquisition of KeySpan Energy Corporation and Transfer of
Assets and Liabilities to the Company" for additional information.)

On November 4, 1999, the Company entered into a definitive  merger  agreement to
acquire all of the common stock of Eastern Enterprises ("Eastern"). Eastern is a
holding company that owns and operates,  primarily, Boston Gas Company, Colonial
Gas Company,  Essex Gas Company and Midland  Enterprises,  Inc. Eastern has also
entered into an agreement to acquire all of the common stock of  EnergyNorth,  a
provider  of gas  distribution  services  to  customers  in New  Hampshire.  The
acquisition of Eastern is conditioned upon, among other things,  the approval of
Eastern  shareholders,  the Securities and Exchange Commission ("SEC") and, with
respect  to the  EnergyNorth  transaction,  the  New  Hampshire  Public  Utility
Commission.  Upon  consummation  of the Eastern  transaction,  the Company  will
become a registered holding company under the Public Utility Holding Company Act
of 1935,  as  amended.  The Company  anticipates  that the  transaction  will be
consummated  in the third or fourth  quarter of 2000, but is unable to determine
when  or if all  required  approvals  will  be  obtained.  (See  Note  11 to the
Consolidated  Financial  Statements,  "Acquisition of Eastern  Enterprises"  for
further details.)

Current  period  consolidated  results of  operations  are reported for the year
ended  December 31, 1999.  In 1998 the Company  changed its fiscal year end from
March 31 to December 31.  Therefore,  results of operations for the period ended
December  31, 1998  reflect the nine month  transition  period  April 1, 1998 to
December 31, 1998 (the "Transition  Period").  The Transition Period consists of
the following: (i) the period April 1, 1998 through May 28, 1998, which reflects
the results of LILCO only prior to the LIPA Transaction and KeySpan Acquisition;
and (ii) the period May 29, 1998 through December 31, 1998, which represents the
results of the fully  consolidated  Company,  which  includes  the  KSE-acquired
companies, i.e. The Brooklyn Union Gas Company ("Brooklyn Union")

                                              2

<PAGE>



and subsidiaries  comprising the Gas Exploration and Production,  Energy Related
Services and Energy  Related  Investment  segments.  As required  under purchase
accounting,  the results of  operations  for all  periods  prior to May 29, 1998
reflect results of LILCO only, and do not include results of KSE.

Due to the change in the composition of the Company's  operations and the change
in the Company's fiscal year, both occurring in 1998,  results of operations for
the year ended December 31, 1999, for the Transition  Period, and for the fiscal
year ended March 31, 1998 are not truly comparable for the following reasons.

Prior to the LIPA Transaction,  LILCO provided fully integrated electric service
to its  customers.  Included  within  electric  rates charged to customers was a
return on the capital  investment in the  generation  and the  transmission  and
distribution  ("T&D") assets, as well as recovery of the electric business costs
to operate the system.  Upon completion of the LIPA  Transaction,  the nature of
the  Company's  electric  business  changed  from  that of owner of an  electric
generation and T&D system, with significant capital investment, to a new role as
owner of the non-nuclear  generation facilities and as manager of the T&D system
now  owned by  LIPA.  In its new  role,  the  Company's  capital  investment  is
significantly  reduced and  accordingly,  its  revenues  under  various  service
contracts with LIPA reflect that reduction.

Also contributing to the  non-comparability  between reporting  periods,  is the
integration of the KSE- acquired  companies since May 29,1998.  The KSE-acquired
companies,  which include the gas  distribution  operations  of Brooklyn  Union,
contribute  significantly to results of operations.  Income available for common
stock for the KSE-acquired companies, for the period January 1, 1998 through May
28, 1998 was $63.4 million and is not reflected in results of operations for the
Transition Period.

The change in the Company's  fiscal year also  contributed  significantly to the
non-comparability between reporting periods. As previously mentioned, results of
operations  for the Transition  Period  reflect  results for the period April 1,
1998 through  December 31, 1998.  As a result,  the  Transition  Period does not
reflect  earnings  from gas  heating-season  operations.  The  Company  realizes
approximately 80% of its gas distribution-related earnings, or approximately 50%
of its consolidated earnings, during the months of January through March, due to
the large percentage of gas heating sales to total gas sales.

Since the  reporting  periods  are not truly  comparable  we have  provided,  in
addition to the  discussion  of the results of operations  between  periods that
follows,  a discussion of operating  results for each  business  segment for the
year ended  December 31, 1999 compared to the full twelve months ended  December
31,  1998.  The  intent of this  additional  disclosure  is to  provide a better
explanation of the variations in operating results between two comparable twelve
month  periods for the Company's on- going  business  activities.  (See "Segment
Review of Operations - Combined Company Comparison".)


The commentary that follows should be read in conjunction  with the Notes to the
Consolidated Financial Statements.

CONSOLIDATED REVIEW OF HISTORICAL RESULTS

EARNINGS SUMMARY

Consolidated  earnings  for  1999  were  $223.9  million,  or $1.62  per  share.
Consolidated  results  for the  Transition  Period  reflected  a loss of  $195.5
million,  or $1.34 per share.  During the Transition  Period,  the Company:  (i)
incurred substantial  non-recurring charges associated with the LIPA Transaction
of $107.9 million after-tax,  or $0.74 per share,  principally  reflecting taxes
associated  with the sale of assets to the Company by LIPA and the  write-off of
certain  regulatory  assets that were no longer  recoverable  under various LIPA
agreements;  (ii) incurred  charges  amounting to $83.5  million  after- tax, or
$0.57 per share,  associated with  implementing an early retirement  program and
charges associated with the write-off of a  customer-billing  system that was in
development;  (iii) made a $20 million donation ($13 million after-tax, or $0.09
per share) to establish the KeySpan  Foundation;  and (iv) recorded an after-tax
non-cash  impairment charge of $54.1 million,  or $0.37 per share,  representing
the Company's  share of the impairment  charge recorded by THEC to recognize the
effect of low wellhead prices on its valuation of proved gas reserves. (See Note
15 to  the  Consolidated  Financial  Statements,  "Costs  Related  to  the  LIPA
Transaction  and  Special  Charges"  for  further  details  of  these  charges.)
Excluding these  non-recurring and special charges,  earnings for the Transition
Period were $63.0  million,  or $0.43 per share.  Earnings for the twelve months
ended  March 31,  1998 were  $310.4  million,  or $2.56 per share,  and as noted
above, reflect results of operations of the former LILCO only.

The increase in Gas Distribution  earnings in 1999 as compared to the Transition
Period and the fiscal  year  ended  March 31,  1998,  reflects,  primarily,  the
addition of Brooklyn  Union from the date of the KeySpan  Acquisition.  Brooklyn
Union's income  available for common stock in 1999 was $109.6 million.  Further,
earnings for the Transition  Period do not include  earnings from heating season
operations   (months  of  January  through  March)  when  the  Company  realizes
approximately 80% of its gas related earnings.  The decrease in earnings for the
Transition  Period as  compared  to the fiscal year ended March 31, 1998 is also
due to the absence of heating  season  operations  associated  with  LILCO's gas
distribution operations during the Transition Period.

In 1999,  earnings from Electric  Services  reflect  service-fees  under various
service  contracts  with LIPA and earnings from the  operations of the Company's
investment  in the  2,168  megawatt  Ravenswood  electric  generation  facility,
("Ravenswood  Facility") located in Queens, New York, purchased in June 1999. In
order  to  reduce  its  cash  requirements,  the  Company  entered  into a lease
agreement with a special purpose,  unaffiliated financing entity that acquired a
portion of the Ravenswood  Facility and leased it to a subsidiary of the Company
under a ten year lease. Electric Services earnings increased in 1999 as compared
to the  Transition  Period due,  primarily to the  acquisition of the Ravenswood
Facility which  contributed $47.5 million to Electric Services earnings in 1999.
Further,  1999 results  reflect a full twelve month period of earnings  from the
service  contracts with LIPA. (For additional  details on the electric  revenues
and the Ravenswood Facility

see  "Electric  Services-  Revenue  Mechanisms"  and Note 9 to the  Consolidated
Financial   Statements,    "Contractual    Obligations,    and   Contingencies",
respectively.)

As previously mentioned,  the Company's operating results under its arrangements
with LIPA are  significantly  lower  than  those  experienced  prior to the LIPA
Transaction,  reflecting  the  change in the  nature of the  Company's  electric
business. As a result, earnings subsequent to the LIPA Transaction reflect these
reduced  margins;  therefore,  earnings for 1999 and the  Transition  Period are
significantly  lower than those  experienced for the fiscal year ended March 31,
1998.

Results  of  operations  in 1999 from Gas  Exploration  and  Production,  Energy
Related Services,  and Energy Related  Investments reflect operations for a full
twelve months as compared to seven months for the  Transition  Period.  Earnings
from Gas Exploration  and Production  operations in 1999 have benefited from the
combined effect of increases in gas production  volumes and gas prices.  Results
of  operations  in  1999  from  Energy  Related   Services  and  Energy  Related
Investments  reflect the  continued  development  and  integration  of companies
acquired over the past few years.

Losses from the Other  segment  reflect  preferred  stock  dividends and general
expenses incurred by the corporate and administrative  areas of the Company that
have not been allocated to the various business  segments,  offset,  in part, by
interest income earned on temporary cash  investments.  Interest income has been
decreasing  as the  Company  continues  to use  cash  to  finance  acquisitions,
repurchase shares of its common stock, and retire maturing debt.

REVENUES

Consolidated  revenues  are  derived,  primarily,  from the  Company's  two core
operating segments - Gas Distribution and Electric Services.  In 1999, these two
core segments  accounted for  approximately  88% of consolidated  revenues.  The
increase in consolidated  revenues of $1.2 billion, or 71%, in 1999, as compared
to the Transition Period, reflects,  primarily, revenues from gas heating sales.
For the months of January 1999 through  March 1999,  gas  distribution  revenues
were $718.3 million or approximately 41% of total gas distribution  revenues for
the entire year. The Transition Period,  which reflects the period April 1, 1998
through  December  31,  1998,  does not include  revenues  from  heating  season
operations for the months of January  through March.  Further,  revenues in 1999
reflect a full twelve  month  period for all  segments,  whereas the  Transition
Period reflects revenues for only seven months from the KSE- acquired companies.
Revenues in 1999 also include  $150.8  million of revenues  from the  Ravenswood
Facility and were further  enhanced from the acquisition of companies  reflected
in the Energy Related Services segment.

Consolidated  revenues for the Transition  Period decreased by $1.4 billion,  or
45%, as compared to the fiscal year ended March 31, 1998 due to the  significant
reduction in electric revenues. Electric revenues for the Transition Period were
derived  from service  agreements  with LIPA for the period May 29, 1998 through
December 31, 1998 and two months of electric services under LILCO. As previously
mentioned,  prior to the  LIPA  Transaction,  LILCO  provided  fully  integrated
electric  service to its customers.  Included  within  electric rates charged to
customers was a return on the

                                              6

<PAGE>



capital  investment in the generation and T&D assets, as well as recovery of the
electric  business  costs to operate the  system.  Upon  completion  of the LIPA
Transaction,  the Company's  capital  investment was  significantly  reduced and
accordingly,  its revenues under the LIPA contracts reflect that reduction. This
change in the nature of the Company's  electric  operations also  contributed to
the  comparative  decrease in  revenues  for 1999 as compared to the fiscal year
ended March 31, 1998.

See Segment  Review of Operations - Combined  Company  Comparison for additional
information regarding revenues for each segment.

OPERATING EXPENSES

Operating  expenses were $2.5 billion in 1999, and $1.8 billion and $2.1 billion
for the  Transition  Period and fiscal year ended March 31, 1998,  respectively.
The increase in 1999 as compared to the Transition Period of $694.7 million,  or
39.1%, is due, in part, to the increased reporting time frame and to an increase
of $248.9 million in operations and maintenance expense  reflecting,  primarily,
the addition of the KSE-acquired  companies.  The decrease in operating expenses
for the Transition Period as compared to the fiscal year ended March 31, 1998 of
$340.7 million or 16.0%, is due,  primarily to the shorter  reporting period and
the  discontinuance  of fuel and  purchased  power expense  associated  with the
electric  generating  facilities on Long Island,  offset, in part, by operations
and maintenance expenses of the KSE-acquired companies.

PURCHASED GAS

Variations in gas costs have little  impact on operating  results as the current
gas rate  structure  of each of the  Company's  two gas  distribution  utilities
includes a gas adjustment clause pursuant to which variations between actual gas
costs and gas cost  recoveries  are  deferred and  subsequently  refunded to, or
collected from customers.  Comparative  variations  between the reported periods
are due to the addition of the  KSE-acquired  companies,  changes in gas volumes
and prices, and the differences in the reporting periods presented.

FUEL AND PURCHASED POWER

Electric  fuel expense was $17.3  million in 1999,  and $91.8 million and $658.3
million for the Transition  Period and for the fiscal year ended March 31, 1998,
respectively. In accordance with the Energy Management Agreement ("EMA") between
the Company and LIPA, LIPA is responsible for paying directly the costs of fuel,
as well as purchased power to satisfy the energy needs of LIPA's customers. As a
result,  since May 29,  1998,  the Company no longer  incurs any  electric  fuel
expense for Long Island  generation or purchased  power  expense.  Electric fuel
expense for 1999 reflects fuel purchases to operate the Ravenswood Facility.

<PAGE>



OPERATIONS AND MAINTENANCE EXPENSE

Operations and maintenance  expense was $1.1 billion in 1999, and $842.3 million
and $511.2  million  for the  Transition  Period and fiscal year ended March 31,
1998,  respectively.  The  increase  in all  periods  was due  primarily  to the
addition of the KSE-acquired  companies.  Operations and maintenance expense for
these  companies  was  $483.6  million  for  1999  and  $284.1  million  for the
Transition  Period.   Further,  the  increase  in  comparative   operations  and
maintenance  expense  in  1999  was  due,  in  part,  to the  operations  of the
Ravenswood  Facility,  which added  $61.3  million to  expense.  Operations  and
maintenance  expense for the Transition  Period  included $63.8 million of costs
associated  with  the  write-off  of a  customer  billing  system  that  was  in
development and a charge of $64.6 million  associated  with an early  retirement
program.

On a comparable twelve month basis however, the Company has realized significant
reductions in operations and  maintenance  expense  derived,  in part, from cost
reduction  measures  and  operating  efficiencies  employed  during the past few
years. To gain a better  perspective of operations and maintenance  expense on a
comparable  twelve  month  basis see  Segment  Review of  Operations  - Combined
Company Comparison.

ELECTRIC REGULATORY AMORTIZATIONS

Prior to the LIPA Transaction,  the Rate Moderation Component ("RMC"),  included
within electric  regulatory  amortizations,  represented the difference  between
LILCO's  revenue  requirements  under  conventional  ratemaking and the revenues
provided by its electric rate structure.

In April 1998,  the New York Public  Service  Commission  (NYPSC")  authorized a
revision, effective December 1, 1997, to LILCO's method of recording its monthly
RMC  amortization.  As a result of this  change,  for the  period  April 1, 1998
through May 28, 1998,  LILCO recorded $51.5 million more of non-cash RMC credits
to income,  or $33.5  million  after-tax,  than it would have under the previous
method.  In addition,  for the fiscal year ended March 31, 1998,  LILCO recorded
approximately  $65.1  million more of non-cash  RMC credits to income,  or $42.5
million  after-tax,  than it would have under the previous method. In connection
with the LIPA  Transaction,  which  included  the sale of all  electric  related
regulatory assets, the RMC and all other electric regulatory  amortizations were
discontinued.

OTHER OPERATING EXPENSES

Depreciation  and depletion  expense  reflects gas utility property and electric
generation  property  additions  for  all  periods  and  electric  T&D  property
additions  for  the  periods  prior  to  the  LIPA  Transaction.   In  addition,
depreciation  and  depletion  expense  in 1999  and for the  Transition  Period,
includes  depletion  expense  associated  with the gas production  activities of
THEC. The decrease in depreciation and depletion  expense in 1999 as compared to
the  Transition  Period is due,  primarily,  to the fact that THEC  recorded  an
impairment  charge of $130  million in December  1998 to reduce the value of its
proved gas reserves in accordance with the asset ceiling test limitations of the
SEC

                                              8

<PAGE>



applicable to gas exploration and development operations accounted for under the
full  cost  method.  Excluding  this  impairment  charge,  depreciation  expense
increased  in all  periods  due to property  additions  and the  addition of the
KSE-acquired  companies.  Offsetting these increases,  in part, is the effect on
depreciation  expense from the sale of  significant  property  related assets to
LIPA as a result of the LIPA Transaction.

Operating taxes  principally  include state and local taxes on utility  revenues
and  property.  The  applicable  property  base  and tax  rates  generally  have
increased in all periods.  The increase in operating  taxes in 1999, as compared
to the Transition  Period,  reflects the addition of the KSE- acquired companies
for a full  twelve  month  period,  and  operating  taxes  associated  with  the
Ravenswood Facility.  Operating taxes associated with the KSE-acquired companies
was $140.8 million in 1999 and $69.8 million during the Transition  Period.  The
Ravenswood  Facility had operating  taxes of $19.6 million in 1999.  Significant
property  related assets were sold to LIPA as part of the LIPA  Transaction and,
as a result,  subsequent to May 28, 1998,  property taxes related to such assets
are no longer  incurred by the Company.  Therefore,  operating taxes in 1999 and
for the Transition Period are significantly lower than for the fiscal year ended
March 31, 1998.

OTHER INCOME AND DEDUCTIONS

Other income includes equity  earnings from  subsidiaries  comprising the Energy
Related  Investments  segment,  primarily  the  Company's  20%  interest  in the
Iroquois Gas  Transmission  System LP  ("Iroquois")  and 50%  investment in Gulf
Midstream Services Partnership ("GMS"). In addition,  other income also includes
interest income from temporary cash investments. Equity earnings in 1999 reflect
twelve  months of results  for  Iroquois  as  compared  to only seven  months of
results for the Transition  Period.  Further,  GMS was acquired in December 1998
and,  therefore,  there  are no  equity  earnings  associated  with  GMS for the
Transition  Period.  The Company  recognized equity earnings of $7.1 million and
$5.8 million for 1999,  from its  investment in Iroquois and GMS,  respectively.
Interest income has decreased in 1999, as compared to the Transition  Period, as
the Company continues to use cash to make acquisitions, repurchase shares of its
common  stock,  and retire  maturing  debt.  Other  income and  deductions  also
includes  the  minority  interest  effect  associated  with  the  Company's  64%
ownership  interest in THEC.  Other  income and  deductions  for the  Transition
Period reflects  non-recurring  charges  associated with the LIPA Transaction of
$107.9 million after- tax and a $20 million before-tax charge for the funding of
the KeySpan Foundation.  (See Note 15 to the Consolidated  Financial Statements,
"Costs Related to the LIPA Transaction and Special Charges".)

Other income and  deductions  for the fiscal year ended March 31, 1998 primarily
includes a charge of $31 million  before-tax  with  respect to certain  benefits
earned  by former  officers  of LILCO  offset by  carrying  charges  on  certain
electric  regulatory assets resulting from electric  ratemaking  mechanisms that
have been discontinued due to the LIPA Transaction.

INTEREST EXPENSE

The  decrease  in interest  expense in 1999 and for the  Transition  Period,  as
compared  to the fiscal  year  ended  March 31,  1998,  primarily  reflects  the
significantly  reduced  level  of  outstanding  debt  resulting  from  the  LIPA
Transaction.   Upon   consummation  of  the  LIPA   Transaction,   LIPA  assumed
substantially  all of the  outstanding  debt of LILCO.  The Company,  in return,
issued  promissory notes to LIPA for its continuing  obligation to pay principal
and interest on certain  series of bonds that were assumed by LIPA.  Outstanding
debt at December 31, 1999 was $1.7  billion as compared to $4.5  billion  (LILCO
only) prior to the LIPA Transaction.  In addition, interest expense in 1999 also
reflects the repayment of $397 million of promissory notes due LIPA that matured
in June 1999. The reduction in interest expense in 1999 from the lower levels of
debt  outstanding  was  offset,  in  part,  by the  interest  expense  from  the
KSE-acquired companies for the full twelve months.

INCOME TAXES

Income tax expense  reflects the level of pre-tax  income in all periods and for
1999,  an  adjustment  to  deferred  tax expense and current tax expense for the
utilization  of  previously  deferred net operating  loss ("NOL")  carryforwards
recorded in 1998. In the Transition Period, the Company recorded,  as a deferred
tax  asset,  a benefit  of $71.1  million  for NOL  carryforwards.  The  Company
estimates  that $57.4  million of the benefits from the NOL  carryforwards  from
1998 will be  realized in its  consolidated  1999  federal and state  income tax
returns, and accordingly, applied the NOL benefits in its 1999 federal and state
tax provisions.  Pre-tax income and the related  deferred income tax expense for
the Transition Period were significantly affected by charges related to the LIPA
Transaction,  the write-off of a customer billing system, charges related to the
early  retirement  program,  and  the  impairment  charge  associated  with  the
write-down of proved gas  reserves.  (See Note 3 to the  Consolidated  Financial
Statements, "Income Tax".)

SEGMENT REVIEW OF OPERATIONS - COMBINED COMPANY COMPARISON

Due to the change in the  structure  of the  Company's  electric  business  as a
result of the LIPA  Transaction  and the  requirements  of  purchase  accounting
applicable  to the KeySpan  Acquisition  (as discussed  previously),  results of
operations  for 1999 are not truly  comparable to the results of operations  for
the Transition Period. For comparative purposes, we have combined the results of
operations,  excluding  non-recurring and special charges,  of KSE and LILCO for
the  entire  twelve  month  period  ended  December  31,  1998.   This  combined
presentation is intended to reflect the results of the Company as if the KeySpan
Acquisition occurred on the first day of the reporting period,  January 1, 1998.
This "combined company basis" format will also be used to explain  variations in
operating  results,  for each business segment,  between the twelve months ended
December 31, 1999 and 1998.

Consolidated  income (loss)  available for common stock,  on a combined  company
basis excluding non- recurring and special charges,  by reporting segment is set
forth in the following table for the periods indicated:

GAS DISTRIBUTION

With the  exception  of a small  portion of Queens  County,  the  Company's  gas
distribution subsidiaries are the only providers of gas distribution services in
the New York City  counties  of Kings,  Richmond  and Queens and the Long Island
counties  of Nassau  and  Suffolk.  Brooklyn  Union  provides  gas  distribution
services to  customers  in the New York City  boroughs of  Brooklyn,  Queens and
Staten  Island,  and KeySpan Gas East  Corporation  d/b/a Brooklyn Union of Long
Island ("Brooklyn Union of Long Island"),  provides gas distribution services to
customers  in the Long Island  counties  of Nassau and Suffolk and the  Rockaway
Peninsula of Queens County.

The table below  highlights  certain  significant  financial  data and operating
statistics for the Gas Distribution segment for the periods indicated.

NET REVENUES

Net gas revenues decreased in 1999 by $12.5 million, or 1.3%, due primarily,  to
rate reductions associated with the KeySpan Acquisition.  Brooklyn Union reduced
rates to its core  customers by $23.9  million on an annual basis  effective May
29, 1998 and Brooklyn  Union of Long Island  reduced its rates to core customers
by $12.2 million annually  effective  February 5, 1998 and by an additional $6.3
million  annually  effective May 29, 1998. For the year ended December 31, 1999,
rate reductions  impacted revenues by approximately $19.2 million as compared to
1998.

Firm sales  quantities,  normalized for weather  variations,  increased by 2.4%,
contributing  approximately  $10 million to net revenues.  Firm sales  additions
were  generated  primarily on Long Island from the addition of new gas customers
and oil to gas  conversions.  Weather  normalized  firm  sales  on  Long  Island
increased by 3.7% and by 1.6% in the Company's New York City service area.  Long
Island has a very low  natural gas  saturation  rate and  significant  gas-sales
growth  opportunities  remain available.  The Company estimates that only 28% of
one and  two-family  homes on Long  Island  currently  use natural gas for space
heating,  while 28% of the multi-family  market and 69% of the commercial market
use gas for space  heating.  In this service area,  the Company will seek growth
through  the  expansion  of its  distribution  system  as  well as  through  the
conversion  of  residential  homes  and the  pursuit  of  opportunities  to grow
multi-family, industrial and commercial markets.

In the Company's service area of the New York City boroughs of Brooklyn,  Queens
and Staten Island,  79% of one and two- family homes currently use gas for space
heating,  while 54% of the multi-family  market and 76% of the commercial market
use gas for space heating.  In these areas,  the Company  intends to seek growth
with an  aggressive  marketing  effort  designed  to  encourage  conversions  of
residential and  multi-family  homes and businesses from fuel oil to natural gas
heating.

In the large volume  heating  markets,  which  include large  apartment  houses,
government  buildings and schools,  gas service is provided under rates that are
set to compete with prices of alternative fuel,  including No. 2 and No. 6 grade
heating  oil.  During  1999,  gas  generally  sold at a premium to heating  oil.
However,  due to the recent increase in the price of heating grade fuel oil, gas
is currently  selling at a discount to heating oil. The Company  increased sales
in this market in 1999, by  approximately  $6 million,  through  aggressive unit
pricing and the addition of new customers.

Contributing  to the reduction in comparative net margins in 1999 was a decrease
in certain  regulatory  incentives  earned by the Company,  offset,  in part, by
revenue benefits associated with colder weather.  Further, since April 1998, net
revenues no longer reflect revenues derived from Brooklyn Union's  appliance and
repair  services  since these services have been  "spun-off" to another  Company
subsidiary and are now reflected in the Energy Related Services segment.

SALES, TRANSPORTATION AND OTHER VOLUMES

Comparative  firm  gas  sales  volumes  increased  by 4.0% in  1999,  due to the
increase in normalized firm sales, as discussed  above, and the benefits derived
from colder weather in 1999 as compared to 1998.

                                              13

<PAGE>



Firm gas  transportation  volumes also increased in 1999, as a result of natural
gas  deregulation  initiatives.  At  December  31,  1999,  approximately  46,000
residential,  commercial and industrial  customers,  with annual requirements of
approximately  22,000  MDTH,  or 10% of the  Company's  annual  firm gas  system
requirements, purchased their gas supply from sources other than the Company, as
compared to 32,900 customers with annual  requirements of  approximately  19,500
MDTH in 1998. The Company's net margins are not affected by customers  opting to
purchase   their  gas  supply  from  sources  other  than  the  Company,   since
distribution  rates  charged to  transportation  customers are the same as those
charged  to  sales  customers.   (See  Item  7A.  Quantitative  and  Qualitative
Disclosures About Market Risk for a discussion of competitive  issues facing the
Company.)

Transportation   volumes   related   to   electric   generation,   reflect   the
transportation of gas to the Company's electric generating facilities located on
Long  Island.   The  Company  began  reporting  these  volumes  since  the  LIPA
Transaction. Net revenues from these volumes are marginal.

Other sales volumes include on-system  interruptible  volumes,  off-system sales
volumes (sales made to customers outside of the Company's  service  territories)
and related transportation. The decrease in these sales reflects, primarily, the
fact that Brooklyn Union  discontinued  its off-system  sales program  beginning
April 1, 1998 and replaced it with a management agreement with Enron Capital and
Trade  Resources  Corp.  and its  parent  company,  Enron  Corp.  (collectively,
"Enron"),  in which Enron pays the Company a fixed fee in exchange for the right
granted Enron to earn revenues based upon its management of Brooklyn Union's gas
supply  requirements,  storage  arrangements,  and off-  system  capacity.  This
agreement  expires on March 31, 2000. The Company  currently is in  negotiations
with a large energy corporation to provide energy supply management  services to
both  Brooklyn  Union and  Brooklyn  Union of Long Island  beginning on April 1,
2000.

OPERATING EXPENSES

Comparative  operating  expenses  decreased in 1999 by $28.4  million,  or 4.3%.
During the year, the Company realized  significant  reductions in operations and
maintenance  expense  reflecting,  primarily,  the  benefits  derived  from cost
reduction  measures  and  operating  efficiencies  employed  during the past few
years.  Such measures  included,  but were not limited to, the early  retirement
program completed in 1998, in which over 600 employees participated. The Company
intends to continue its on-going cost  containment  initiatives  and anticipates
further reductions in operations and maintenance  expenses in 2000. In addition,
Brooklyn Union's  "spin-off" of non-safety  related appliance repair services to
KeySpan Energy Solutions LLC, a Company subsidiary, in April 1998 contributed to
the reduction in operations and maintenance  expense for this segment.  Brooklyn
Union of Long Island discontinued  providing non-safety related appliance repair
services on July 1, 1999, further reducing operating expenses for this segment.

The  increase  in  depreciation  and  amortization  expense  reflects  continued
property additions and, more significantly,  amortization of previously deferred
merger related expenses. As provided for in the Stipulation Agreement,  which in
effect  approved  the  KeySpan  Acquisition,   the  Company's  gas  distribution
subsidiaries  deferred  certain  merger related costs at the time of the merger.
These costs

                                              14

<PAGE>



are being amortized over a ten year period. (See Gas Distribution - Rate Matters
for further  details on the  Stipulation  Agreement.)  Further,  operating taxes
which include state and local taxes on property have increased as the applicable
property base and tax rates generally have increased.

EARNINGS

Earnings increased in 1999 by $17.5 million, or 13.1% due primarily,  to the net
result  of the  aforementioned  items.  In  addition,  earnings  were  favorably
affected  by  carrying  charges  on  certain  regulatory   deferrals  previously
mentioned and lower interest expense.

ELECTRIC SERVICES

The Electric  Services segment  primarily  consists of subsidiaries that own and
operate  oil and gas fired  generating  plants in Queens  and Long  Island,  and
through  long-term  contracts,  manage the  electric  T&D  system,  the fuel and
electric  purchases,  and the off-system  electric sales for LIPA.  Prior to the
LIPA Transaction, LILCO provided fully integrated electric distribution services
to over one million customers on Long Island.

Selected  financial data for the Electric  Services  segment is set forth in the
table below for the periods indicated.

REVENUES

Revenues  related to the LIPA  service  contracts  have  increased  in 1999,  as
compared to the Transition Period, due primarily, to the fact that 1999 reflects
a full year of  operations  under these  contracts.  In  addition  in 1999,  the
Company earned $15.8 million  associated  with non-cost  performance  incentives
provided for under these agreements,  as compared to the maximum incentive level
of $16.5 million.  (See Electric  Services- Revenue  Mechanisms- LIPA Agreements
for a further  description of these agreements.)  Revenues were further enhanced
in 1999 by the  operations of the Ravenswood  Facility.  Total revenues in 1999,
however,  decreased  by  $432.4  million,  or 33.4%,  as  compared  to 1998.  As
previously  indicated,  in addition to revenues  from the  Ravenswood  Facility,
electric  revenues  are also derived from  service  agreements  with LIPA.  As a
result of the change in the nature of the Company's  electric  operations due to
the  LIPA  Transaction,  the  Company's  electric  capital  investment  has been
significantly  reduced and accordingly,  its revenues and margins under the LIPA
contracts reflect that reduction.

OPERATING EXPENSES

Operating  expenses in 1999 decreased by $216.0 million,  or 23.0%,  compared to
1998,  reflecting  primarily,  the  discontinuance  of fuel and purchased  power
expense  associated with the generating  facilities  located on Long Island.  In
accordance  with the EMA, LIPA is responsible  for paying  directly the costs of
fuel, as well as purchased power to satisfy LIPA's customers.  As a result,  the
Company  since May 29, 1998 no longer  incurs any electric fuel expense for Long
Island generation or purchased power expense. Further,  depreciation expense and
operating  taxes  have  also  decreased  in 1999 due to the sale of  significant
property related assets to LIPA as a result of the LIPA Transaction.  Offsetting
these  reductions  is  the   discontinuance   of  certain  electric   regulatory
amortizations,  as  previously  discussed,  and an  increase in  operations  and
maintenance  expense.  Since the LIPA  Transaction,  operations and  maintenance
expense  includes the costs  associated  with the  management  of the T&D assets
acquired by LIPA. All T&D related costs are expensed when incurred and recovered
from  LIPA  through  monthly  billings  in  accordance  with  the  terms  of the
Management  Services  Agreement entered into between the Company and LIPA. Prior
to the LIPA Transaction, all T&D related construction costs were capitalized and
charged to  depreciation  expense over the estimated  useful life of the related
asset.

EARNINGS

In addition to the effect on earnings from the above mentioned  items,  earnings
in 1999 were  favorably  affected  by a decrease  of $135.3  million in interest
expense reflecting the significantly reduced level of outstanding debt resulting
from  the  LIPA  Transaction.   Further,   prior  to  the  KeySpan  Acquisition,
approximately  $18.2  million of preferred  stock  dividends  were  allocated to
electric operations.  Partially offsetting these benefits was the elimination of
carrying charges on certain electric  regulatory  assets resulting from electric
ratemaking mechanisms that have been discontinued due to the LIPA Transaction.

GAS EXPLORATION AND PRODUCTION

The Gas Exploration and Production segment is engaged in gas and oil exploration
and production,  and the development and acquisition of domestic natural gas and
oil properties.  This segment consists,  primarily,  of the Company's 64% equity
interest in THEC.  In September  1999,  the Company and THEC  jointly  announced
their intention to begin a process to review  strategic  alternatives  for THEC.
The process  included  an  assessment  of the role of THEC within the  Company's
strategic plans,  including the possible sale of all or a portion of THEC by the
Company. After completing the review, the Company concluded that it would retain
its equity interest in THEC.  Further,  under a pre-existing credit arrangement,
approximately  $80 million in debt owed by THEC to the Company will be converted
into common  equity on April 1, 2000.  The  Company's  common  equity  ownership
interest in THEC will increase to approximately 70% upon such conversion.

Selected  financial data and operating  statistics for the Gas  Exploration  and
Production  segment  are set  forth  in the  following  table  for  the  periods
indicated.

OPERATING INCOME

Operating income increased by $28.5 million,  or 142.2%,  in 1999 as compared to
1998, due to higher  revenues and, to a lesser  extent,  a decrease in operating
expenses.  Revenues in 1999 reflect the benefits  derived from a 13% increase in
production volumes,  combined with an 4% increase in average realized gas prices
(average  wellhead  price received for  production  including  hedging gains and
losses).  At  December  31,  1999,  THEC had 541 BCFe of net proved  reserves of
natural gas, of which 75% was classified as proved  developed.  The  comparative
decrease in operating expenses in

                                              18

1999 was largely due to a lower  depletion rate resulting,  primarily,  from the
ceiling test write down in 1998.

EARNINGS

Operating  income above  represents  100% of THEC's actual  results for 1999 and
1998, excluding the impairment charge.  Earnings however,  reflect the Company's
64% ownership  interest.  This principally  accounts for the difference  between
operating income and earnings.  Additionally, THEC incurred $8.7 million more in
interest expense in 1999 due to higher levels of debt outstanding.

ENERGY RELATED SERVICES

The Company's Energy Related Services segment primarily  includes KeySpan Energy
Management  Inc.  ("KEM"),   KeySpan  Energy  Services  Inc.  ("KES"),   KeySpan
Communications  Corporation,  KeySpan Energy  Solutions,  LLC ("KESol"),  Fritze
KeySpan,  LLC ("Fritze"),  and Delta KeySpan Inc. ("Delta").  These subsidiaries
own,  design  and/or  operate  energy  systems  for  commercial  and  industrial
customers and provide energy-related appliance services and heating, ventilation
and air conditioning system installation and maintenance services to residential
and commercial  clients located  primarily within the New York City metropolitan
area and Rhode Island. In addition, subsidiaries in this segment: market gas and
electricity,  and arrange transportation and related services, largely to retail
customers,  including  those  served  by  the  Company's  two  gas  distribution
subsidiaries;  and  own  a  fiber  optic  network  on  Long  Island.  KESol  was
established  in April 1998,  Fritze was acquired in November  1998 and Delta was
acquired in September 1999.

The table below highlights selected financial information for the Energy Related
Services segment.

================================================================================


The  decrease in the loss in 1999 as compared to 1998,  is due to an increase in
revenues of 112%,  offset, in part, by an increase in operating expenses of 86%.
The  increase in  comparative  revenues  was due, in part,  to the  inclusion of
revenues from Fritze for a full twelve month period.  Fritze  contributed  $39.6
million to the increase in segment revenues in 1999.  Delta, the Company's newly
acquired  heating,   ventilation  and  air  conditioning   ("HVAC")  contractor,
contributed  revenues of $12.3 million in 1999.  Further,  the combined revenues
from KEM, KES and KESol  increased by $43.9 million in 1999, due to the benefits
derived from companies  acquired during the past two years and the growth in the
number of customers purchasing energy from KES and services from KESol.

The  comparative  increase  in  operating  expenses  for both  periods,  was due
primarily, to the acquisition of Fritze and Delta, the integration of operations
of other companies  acquired during the past few years, and increased  purchased
gas costs of KES necessary to serve a larger  customer  base.  The formation and
commencement  of operations of KESol,  in April 1998,  also  contributed  to the
comparative increase in operating expenses in 1999.

The Company has been  successful in  integrating  the operations of its recently
acquired  companies into its consolidated  operations.  Fritze,  Delta and other
energy management  operations  posted profitable  results in 1999. KES and KESol
both incurred  losses in 1999, as both companies  seek to establish  significant
market penetration.  Gas deregulation of commodity purchases in the Northeast is
still in its infancy and gas sales margins have remained slim,  contributing  to
the loss incurred by KES. In February 2000, the Company acquired three companies
that provide  energy  related  services in the New York  metropolitan  area with
combined revenues of approximately  $170 million.  The newly acquired  companies
include, an  engineering-consulting  firm, a plumbing and mechanical contracting
firm, and a firm specializing in mechanical contracting and HVAC.

ENERGY RELATED INVESTMENTS

Earnings  for this  segment are  derived,  primarily,  from the  Company's:  20%
interest in the Iroquois Gas Transmission  System LP; 50% ownership  interest in
Gulf Midstream  Services  Partnership  ("GMS");  and 50% interest in the Premier
Transco  Pipeline and a 24.5% interest in Phoenix  Natural Gas, both in Northern
Ireland.

Comparative  earnings  from this  segment  increased  by $13.9  million in 1999,
reflecting,  primarily, earnings from the Company's investment in GMS, formed in
December 1998, and more favorable  results from investments in Northern Ireland.
In addition,  in 1998 results of operations from this segment reflect  after-tax
costs of $7.8 million to settle certain  contracts  associated with the sale, in
1997,  of  certain   cogeneration   investments   and  related  fuel  management
operations.  These  subsidiaries are accounted for under the equity method since
the Company's  ownership interests are 50% or less.  Accordingly,  equity income
from these  investments  is reflected in other  income and  (deductions)  in the
Consolidated Statement of Income.


OTHER

The Other segment incurred a loss of $26.7 million in 1999 compared to income of
$1.3 million in 1998 and,  generally,  reflects  preferred  stock  dividends and
charges incurred by the corporate and  administrative  areas of the Company that
have not been allocated to the various business  segments,  offset,  in part, by
interest income earned on temporary cash  investments.  Interest income has been
decreasing  as  the  Company  continues  to  utilize  cash  to  finance  certain
acquisitions,  repurchase  shares of its common stock, and retire maturing debt.
Also, all preferred stock dividends were allocated to the Other segment in 1999,
whereas,  prior to the LIPA Transaction preferred stock dividends were allocated
to gas and electric operations.

FUTURE OUTLOOK

Results of operations  for 1999 reflect  strong  results from the Company's core
gas-distribution  operations.  These results reflect gas sales growth, primarily
on Long Island,  as the benefits from the  Company's  gas expansion  initiatives
begin to be realized.  Gas sales growth on Long Island was  approximately  4% in
1999,  after  normalizing  for weather  variations.  Moreover,  ongoing  synergy
programs have proven to be  successful.  In addition,  the  Company's  June 1999
acquisition of the  Ravenswood  Facility  provided the Company with  significant
earnings  enhancement.  Results  from  operations  of  the  Ravenswood  Facility
contributed  $0.34 per share to  consolidated  earnings  in 1999.  Finally,  the
successful  integration of companies  purchased by the Energy  Related  Services
segment are expected to form the basis for additional  benefits to  consolidated
earnings in future years.

For 2000, the Company intends to continue its gas distribution growth activities
throughout its service  territory,  and  especially on Long Island,  through the
conversion  of  residential  homes  and the  pursuit  of  opportunities  to grow
multi-family, industrial and commercial markets. Gas sales growth throughout the
Company's service territory in 2000, is anticipated to grow at approximately the
same  rate as 1999.  As the  Company  evolves  within  the new  deregulated  gas
environment,  gas sales growth will remain a critical core strategy. The Company
sells gas to its firm customers at the Company's cost for such gas. In addition,
rates include a charge to recover the costs of distribution,  including a profit
margin for return of and on invested  capital.  As the Company adds customers to
its  gas   distribution   network,   the  Company's  gross  profit  margin  from
transportation  sales  should  increase  incrementally.  As a  result,  customer
additions are and will remain critical to the Company's earnings  enhancement in
the future, regardless of whether a customer purchases gas from the Company or a
third party supplier.

Further,  the Company intends to grow its Energy Related Services  operations in
order to deliver an extensive array of home energy-related services and business
solutions to a broad spectrum of customers.  These operations are expected to be
enhanced through the acquisition of companies providing energy-related services.
In line with this strategy, as previously mentioned,  the Company acquired three
additional companies, in February 2000 that provide energy-related services.

A key component in the Company's  strategy for growth in the Northeast region is
its anticipated  acquisition of Eastern. In November 1999, the Company announced
that it has signed a definitive  agreement  with Eastern under which the Company
will acquire all of the common stock of Eastern.  Eastern is the largest natural
gas distribution company in New England with significant upside potential due to
the  relatively low  penetration of customers  using gas for heat in the region.
The  Northeast  region  represents  a  significant   portion  of  the  country's
population and energy consumption.  With recent price spikes for fuel oil in the
Northeast,  the Company  anticipates  even  stronger  demand for natural gas and
related  services.  Together,  KeySpan and Eastern will have  approximately  2.4
million customers making the "new" company the largest gas distribution  company
in the Northeast. Further, the Company expects pre-tax annual synergy savings to
be approximately $30 million. The transaction,  which will be accounted for as a
purchase,  is expected to close in the third or fourth  quarter of calendar year
2000. Upon consummation of the transaction, the Company will become

                                              23

<PAGE>



a registered  holding  company under the Public Utility  Holding  Company Act of
1935,  as  amended.  The  transaction  has a total value of  approximately  $2.5
billion ($1.7  billion in equity and $0.8 billion in assumed  debt.) See Note 11
to the Consolidated  Financial Statements,  "Acquisition of Eastern Enterprises"
for additional information on the transaction.

As  mentioned,  the Company  intends to continue its gas  expansion  initiatives
throughout  its service  territory,  and  especially  on Long  Island,  and will
continue  to seek  additional  synergies  in all its  operations.  In 2000,  the
Company   anticipates   continued  earnings  growth  in  core   gas-distribution
operations,  full  annual  benefits  from  the  Ravenswood  Facility,  continued
successful  integration of companies providing  energy-related  services and gas
sales  growth from the  acquisition  of  Eastern.  To ensure that its assets are
utilized in the most effective  manner,  the Company will continue to review and
evaluate the strategic nature of all its assets deployed.

LIQUIDITY, CAPITAL EXPENDITURES AND FINANCING, AND DIVIDENDS

LIQUIDITY

The increase in cash flow from  operations in 1999 as compared to the Transition
Period,  reflects the  significant  positive  cash flows that are realized  from
revenues  generated during a heating season,  continued strong results from core
utility  operations,  cash  generated  from  the  Ravenswood  Facility,  and the
benefits  derived from the integration of  KSE-acquired  companies for an entire
twelve month period. Approximately 75% of total annual gas revenues are realized
during  the  heating  season  (November  1 to April 30) as a result of the large
proportion  of  heating  sales  compared  to  total  gas  sales.   Results  from
gas-heating  season  operations are not reflected in the Transition  Period,  as
previously  explained.  Further,  cash flow from operations in 1999 reflects the
utilization  of a  $57.4  million  NOL on  income  tax  payments  for  1999,  as
previously discussed.  Moreover,  during the Transition Period, $250 million was
funded into  Voluntary  Employee  Beneficiary  Trusts to fund  certain  employee
postretirement  welfare benefits and, as a result, cash flow from operations for
the Transition Period was adversely  affected.  The slight decrease in cash flow
from  operations  in 1999 as compared  to the fiscal year ended March 31,  1998,
reflects,  primarily, lower margins realized from electric operations due to the
LIPA Transaction,  as previously  discussed,  offset, in part, by increased cash
flows from KSE-acquired companies and utilization of the NOL.

At December 31, 1999,  the Company had cash and temporary  cash  investments  of
$128.6 million compared to $942.8 million at December 31, 1998. During the year,
the Company  deployed its cash to, among other things:  acquire a portion of the
Ravenswood  Facility  for a cash  requirement  of  approximately  $214  million;
purchase  shares of its common  stock on the open market for $299  million;  and
retire maturing debt of $397 million. In addition, the Company utilized its cash
on-hand and internally  generated funds to expand its gas distribution  network,
primarily on Long Island and expand its operations through increased investments
in energy-related activities.

In November  1999,  the  Company  negotiated  a $700  million  revolving  credit
agreement,  with a one- year term and one-year renewal option, with a commercial
bank. This credit facility is used to

                                              24

<PAGE>



support the Company's $700 million  commercial  paper  program.  At December 31,
1999,  the Company had $208.3  million of  commercial  paper  outstanding  at an
annualized  interest rate of 6.56%.  The proceeds  received from the issuance of
commercial paper were used to repay  outstanding  borrowings under the Company's
previous  existing line of credit  (discussed  below) and for general  corporate
purposes.  During 2000, the Company  anticipates issuing commercial paper rather
than  borrowing  on  the  revolving  credit  agreement.   (See  Note  8  to  the
Consolidated  Financial  Statements,  "Notes Payable" for further information on
the credit agreement.)

Prior to the new revolving credit  agreement and commercial  paper program,  the
Company  had an  available  unsecured  bank  line of  credit  of  $300  million.
Borrowings were made under the facility during the months of September,  October
and November 1999 to finance seasonal working capital needs. This line of credit
was terminated upon the execution of the new revolving credit agreement.

In addition,  THEC has an unsecured  available  line of credit with a commercial
bank that provides for a maximum commitment of $250 million,  subject to certain
conditions.  During 1999,  THEC  borrowed $48 million under this facility and at
December 31, 1999, $181 million was outstanding.  Also, a subsidiary included in
the Energy  Related  Investment  segment has a revolving  loan  agreement with a
financial  institution in Canada.  Borrowings  under this agreement  during 1999
were  U.S.$13.5  million,  and at  December  31,  1999,  U.S.$86.4  million  was
outstanding.  (See Note 7 to the Consolidated  Financial Statements,  "Long-Term
Debt" for further information on these agreements.)


CAPITAL EXPENDITURES AND FINANCING

Capital Expenditures
Consolidated  capital  expenditures  during  1999 were  $725.7  million  and are
reflected in the following business segments.

Capital expenditures related to the Gas Distribution segment were $213.8 million
in 1999 and were primarily for the renewal and replacement of mains and services
and for the expansion of the gas distribution system on Long Island.

Electric  Services  had capital  expenditures  of $245.2  million  during  1999,
reflecting  primarily,  the Company's  June 1999  acquisition  of the Ravenswood
Facility.  As a means of financing the  acquisition,  the Company entered into a
lease  agreement  with a special  purpose,  unaffiliated  financing  entity that
acquired a portion of the facility  directly  from Con Edison and leased it to a
subsidiary of the Company. The acquisition cost of the facility was $597 million
and the lease  program was  established  in order to reduce the  Company's  cash
requirement  by $425  million.  The  balance of the funds  needed to acquire the
facility,  including the purchase of inventory and materials,  was approximately
$214 million and was provided from cash on hand. (See Note 9 to the Consolidated
Financial  Statements,  "Contractual  Obligations  and  Contingencies"  for more
details on the lease agreement.) Capital  expenditures during 1999 also included
costs to maintain the generating facilities located on Long Island.

                                              25

<PAGE>



Capital  expenditures  related to Gas  Exploration  and  Production  were $183.3
million  during 1999.  These  capital  expenditures  reflected,  in part,  costs
related to the development of properties  acquired in Southern  Louisiana and in
the Gulf of Mexico  and costs  related  to the  continued  development  of other
properties previously acquired. Capital expenditures also included $35.6 million
related to the Company's  joint venture with THEC to explore for natural gas and
oil. The Company will commit  approximately  $25 million to the drilling program
in 2000.  The joint  venture may be  terminated,  upon notice,  at the option of
either party at the end of a given calendar quarter.

Capital  expenditures  of $20.6  million  during 1999 related to Energy  Related
Services,  includes the acquisition of HVAC  contractors in Rhode Island and New
Jersey that build and install HVAC systems primarily for commercial customers.

Capital  expenditures  related to the Energy  Related  Investments  segment were
$49.4 million  during 1999.  In 1999,  the Company,  through GMS,  completed the
acquisition of Richland  Petroleum's 37% interest in the Paddle River Gas Plant.
The gas plant,  located in Alberta,  Canada,  is capable of  processing up to 82
million cubic feet of gas per day. In addition,  in December  1999,  the Company
purchased   certain  oil   properties  in  Alberta,   Canada  that  can  produce
approximately 1600 barrels of oil per day. Capital  expenditures related to this
segment  also include the  Company's  share of capital  expenditures  in GMS and
expenditures for the on-going expansion and upgrade of a gas distribution system
in Northern Ireland, in which the Company has a 24.5% ownership interest.

Common plant capital  expenditures  were $13.4  million  during 1999 and reflect
primarily,   the  purchase  of  computer  equipment  and  miscellaneous   office
equipment.

Consolidated capital expenditures for 2000, exclusive of expenditures  necessary
for the Eastern acquisition, are estimated to be at approximately the same level
as 1999.  The amount of future  capital  expenditures  is reviewed on an ongoing
basis  and  can  be  affected  by  timing,   scope  and  changes  in  investment
opportunities.

Financing
In October 1999, the Company's wholly-owned subsidiary,  KeySpan Generation, LLC
issued,  through the New York State Energy Research and  Development  Authority,
$41.1 million of Pollution  Control  Revenue Bonds,  1999 Series A. The proceeds
from this  financing  were used to  extinguish  $45.5  million of the  Company's
promissory  notes due LIPA. The initial interest rate on these tax- exempt bonds
was  established  at  3.95%,  which  rate  applies  through  January  13,  2000.
Thereafter,  the interest rate will be reset based on an auction procedure.  The
Company  anticipates  that the interest rate on these  tax-exempt  bonds will be
substantially  lower  than the  interest  rate on the two  series of bonds it is
replacing, which were 7.50% and 7.80%.

In December 1999,  Brooklyn Union of Long Island and the Company jointly filed a
shelf  registration  statement with the SEC in anticipation  of issuing,  during
2000,  up to $600  million of Medium Term  Notes.  These notes will be issued by
Brooklyn Union of Long Island and unconditionally  guaranteed by the Company. On
February 1, 2000, Brooklyn Union of Long Island issued $400 million 7.875

                                              26

<PAGE>



% Notes due  February  1, 2010,  the net  proceeds of which were used to replace
$397  million of the  Company's  promissory  notes due LIPA that matured in June
1999. (See Note 7 to the Consolidated Financial Statements, "Long-Term Debt" for
a further  discussion of these  financings  and the  associated  repayments of a
portion of the promissory notes.)

In addition to the above financing,  the Company intends to access the financial
markets in 2000 to replace maturing  preferred stock and to finance the purchase
of Eastern. In June 2000, $363 million of preferred stock series 7.95% Series AA
will mature.  The Company currently  anticipates  issuing  additional  preferred
stock to replace this maturing  series.  The timing of this issuance will depend
on market conditions during 2000.

As  previously  mentioned,  on November  4, 1999,  the  Company  entered  into a
definitive  agreement  with Eastern,  pursuant to which the Company will acquire
all of the  outstanding  common stock of Eastern.  The  transaction  has a total
value of approximately  $2.5 billion ($1.7 billion in equity and $0.8 billion in
assumed debt and preferred stock).  The Company expects to raise $1.7 billion of
initial  financing to purchase  Eastern in  short-term  markets,  a  significant
portion  of  which  will  be  replaced  with  long-term  financing  as  soon  as
practicable thereafter.

In  connection  with the  Company's  anticipated  purchase  of  Eastern  and the
anticipated  issuance of long-term  debt  securities,  the Company  entered into
forward  interest rate lock  agreements in January and February 2000, to hedge a
portion of the risk that the cost of the future  issuance of fixed-rate debt may
be adversely  affected by changes in interest rates. The agreements have a total
notional  principal  amount of $400  million.  (See Note 10 to the  Consolidated
Financial  Statements,  "Hedging,  Derivative  Financial  Instruments  and  Fair
Values" for additional details.)

In 1998, the Company's Board of Directors authorized the repurchase of a portion
of the Company's outstanding common stock. The initial  authorization  permitted
the repurchase of up to 10 percent of the Company's then  outstanding  stock, or
approximately  15 million  common  shares.  A second  authorization  permits the
Company to use up to an  additional  $500  million of cash for the  purchase  of
common shares.  As of December 31, 1999, the Company had  repurchased 25 million
of its common shares for $723 million.

During 2000,  the Company will  continue its on-going  evaluation of its capital
structure  and its debt and  equity  levels.  Further,  the  Company  intends to
actively manage its balance sheet to maintain  investment  grade ratings at each
of its rated entities. At December 31, 1999 the Company's ratio of debt to total
capitalization  was 35%.  The Company  estimates  that,  based on its  projected
financings  in  2000,  its  ratio  of  debt  to  total  capitalization  will  be
approximately 60% at the end of 2000,  assuming a certain level of dividends and
earnings.

DIVIDENDS

The Company is currently paying a dividend at an annual rate of $1.78 per common
share.  The  Company's  dividend  policy is  reviewed  annually  by the Board of
Directors. The amount and timing

                                              27

<PAGE>



of all dividend  payments is subject to the discretion of the Board of Directors
and will depend  upon  business  conditions,  results of  operations,  financial
conditions and other factors.

Pursuant  to the  NYPSC's  orders  dated  February  5, 1998 and  April 14,  1998
approving the KeySpan  Acquisition,  Brooklyn Union's and Brooklyn Union of Long
Island's  ability to pay  dividends to the parent  company is  conditioned  upon
maintenance of a utility capital  structure with debt not exceeding 55% and 58%,
respectively,  of  total  utility  capitalization.  In  addition,  the  level of
dividends  paid by both  utilities may not be increased from current levels if a
40 basis  point  penalty is  incurred  under the  customer  service  performance
program. At the end of Brooklyn Union's and Brooklyn Union of Long Island's rate
years  (September  30, 1999 and November 30, 1999,  respectively),  the ratio of
debt to total utility  capitalization was 44% and 47%,  respectively.  Moreover,
upon consummation of the acquisition of Eastern, the Company expects to register
as a holding  company under the Public Utility  Holding  Company Act of 1935, as
amended. As a result, the corporate and financial  activities of the Company and
each of its  subsidiaries  (including  their  ability  to pay  dividends  to the
Company) will also be subject to regulation by the SEC.

GAS DISTRIBUTION - RATE MATTERS

By  orders  dated  February  5, 1998 and April  14,  1998 the NYPSC  approved  a
Stipulation Agreement  ("Stipulation") among Brooklyn Union, LILCO, the Staff of
the Department of Public  Service and six other parties that in effect  approved
the KeySpan  Acquisition  and  established gas rates for both Brooklyn Union and
Brooklyn Union of Long Island.  Under the Stipulation,  $1 billion of efficiency
savings,  excluding  gas costs,  attributable  to operating  synergies  that are
expected to be realized over the 10 year period following the combination,  were
allocated to ratepayers net of transaction costs.

Under the  Stipulation,  effective May 29, 1998,  Brooklyn Union's base rates to
core customers  were reduced by $23.9 million  annually.  In addition,  Brooklyn
Union is now subject to an earnings sharing provision  pursuant to which it will
be required to credit core customers with 60% of any utility  earnings up to 100
basis points above  certain  threshold  return on equity levels over the term of
the rate plan (other than any earnings associated with discrete  incentives) and
50% of any utility  earnings in excess of 100 basis points above such  threshold
levels.  The threshold  levels are 13.50% for the rate years ended September 30,
1999 through  2001,  and 13.25% for the rate year 2002.  Brooklyn  Union did not
earn above its threshold return level in its rate year ended September 30, 1999.

The Stipulation also required Brooklyn Union of Long Island to reduce base rates
to its customers by $12.2 million annually  effective February 5, 1998 and by an
additional $6.3 million annually effective May 29, 1998.  Brooklyn Union of Long
Island is subject  to an  earnings  sharing  provision  pursuant  to which it is
required to credit to firm  customers  60% of any  utility  earnings in any rate
year up to 100 basis  points  above a return on equity of 11.10%  and 50% of any
utility  earnings in excess of a return on equity of 12.10%.  Brooklyn  Union of
Long Island did not earn above its threshold return level in its rate year ended
November 30, 1999. At the  conclusion of the Brooklyn  Union of Long Island rate
plan on November 30, 2000, Brooklyn Union of Long Island or the NYPSC on its own
motion,  may  initiate  a  proceeding  to revise  the rates and  charges of that
company.

ELECTRIC SERVICES - REVENUE MECHANISMS

LIPA AGREEMENTS

The Company,  through  certain of its  subsidiaries,  provides  services to LIPA
under the following agreements:

Management Services Agreement ("MSA")

A Company subsidiary manages the day-to-day operations,  maintenance and capital
improvements of the T&D system.  LIPA will exercise control over the performance
of the T&D system through specific standards for performance and incentives.  In
exchange for providing the services,  the Company will earn a $10 million annual
management fee and will be operating under an eight-year contract which provides
certain  incentives and imposes certain  penalties  based upon its  performance.
Annual service  incentives or penalties  exist under the MSA if certain  targets
are  achieved  or not  achieved.  In  addition,  the  Company  can earn  certain
incentives  for  cost  reductions  associated  with the  day-to-day  operations,
maintenance  and capital  improvements  of LIPA's T&D system.  These  incentives
provide for the Company to (i) retain  100% of cost  reductions  on the first $5
million in reductions,  and (ii) retain 50% of additional  cost reductions up to
15% of the total cost budget,  thereafter all savings will accrue to LIPA.  With
respect to cost  overruns,  the  Company  will  absorb the first $15  million of
overruns,  with a sharing  of  overruns  above $15  million.  There are  certain
limitations on the amount of cost sharing of overruns.  To date, the Company has
performed its obligations  under the MSA within the agreed to budget  guidelines
and the Company is committed to providing  on-going  services to LIPA within the
established  cost  structure.  However,  no assurances can be given as to future
operating results under this agreement.

Power Supply Agreement ("PSA")

A  Company  subsidiary  sells to LIPA all of the  capacity  and,  to the  extent
requested,  energy from the  Company's  existing  oil and  gas-fired  generating
plants.  Sales of  capacity  and  energy are made under  rates  approved  by the
Federal Energy Regulatory Commission ("FERC").  The rates may be modified in the
future in  accordance  with the terms of the PSA for (i)  agreed  upon labor and
expense  indices  applied to the base year,  (ii) a return of and on net capital
additions required for the generating facilities,  and (iii) reasonably incurred
expenses  that are  outside the control of the  Company.  Rates  charged to LIPA
include a fixed and variable component. The variable component is billed to LIPA
on a monthly basis and is dependent on the amount of megawatt hours  dispatched.
LIPA has no  obligation  to  purchase  energy  from the  Company  and is able to
purchase energy on a least-cost basis from all available sources consistent with
existing  interconnection  limitations  of the T&D  system.  The  Company  must,
therefore,  operate its generating  facilities in a manner such that the Company
can remain  competitive with other producers of energy. To date, the Company has
dispatched  to LIPA and LIPA has accepted  the level of energy  generated at the
agreed to price per megawatt hour. However, no assurances can be given as to the
level  and  price of  energy to be  dispatched  to LIPA in the  future.  The PSA
provides incentives and penalties that can total $4 million annually for the

                                              29

<PAGE>



maintenance of the output capability of the generating facilities.  The PSA runs
for a term of fifteen
years.

In addition,  beginning on May 28, 2001, LIPA will have the right for a one-year
period to acquire all of the  Company's  Long  Island  based  generating  assets
included in the PSA at the fair market  value at the time of the exercise of the
right, which value will be determined by independent appraisers.

Energy Management Agreement ("EMA")

The EMA provides for a Company  subsidiary  to procure and manage fuel  supplies
for LIPA to fuel the  generating  facilities  under  contract  to it and perform
off-system  capacity and energy  purchases on a least-cost  basis to meet LIPA's
needs.  In exchange for these  services the Company  earns an annual fee of $1.5
million. In addition, the Company will arrange for off-system sales on behalf of
LIPA of excess output from the  generating  facilities  and other power supplies
either owned or under  contract to LIPA.  LIPA is entitled to  two-thirds of the
profit  from  any  off-system  energy  sales.  In  addition,  the  EMA  provides
incentives  and  penalties  that can total $7 million  annually for  performance
related to fuel  purchases  and  off-system  power  purchases.  The EMA covers a
period of fifteen years for the procurement of fuel supplies and eight years for
off-system management services.

RAVENSWOOD FACILITY

At the time of the Company's  purchase of the Ravenswood  Facility,  the Company
and Con Edison entered into energy and capacity  contracts.  The energy contract
provided Con Edison with 100% of the energy produced by the Ravenswood  Facility
and covered a period of time from the date of closing,  June 18,  1999,  through
November 18, 1999. With the start-up of the New York Independent System Operator
("NYISO")  the  electricity  market in New York  City  began a  transition  to a
competitive  market for  capacity,  energy and ancillary  services.  Starting on
November  18,  1999,  the  Company  began  selling  the energy  produced  by the
Ravenswood  Facility  through daily and/or hourly  bidding into the NYISO energy
markets.  The Company also has the option to sell all or a portion of the energy
produced by the  Ravenswood  Facility to Load  Serving  Entities  ("LSE"),  i.e.
entities  that sell to  end-users.  At this point in time,  the Company has sold
energy exclusively  through the NYISO. The capacity contract,  which is still in
effect,  provides  Con  Edison  with  100%  of  the  available  capacity  of the
Ravenswood  Facility.  The Company anticipates that this contract will expire on
April 30, 2000, at which time the available capacity of the Ravenswood  Facility
will be bid into on the auction process conducted by the NYISO. The Company also
has the  option  to  sell  the  capacity  through  contracts  with  LSEs.  It is
anticipated  that in  2000,  at least  75% of the net  profit  margins  from the
Ravenswood  Facility  will be derived from  capacity  sales  through  either the
auction process associated with the NYISO or contracts with LSEs.

ENVIRONMENTAL MATTERS

The Company is subject to various  federal,  state and local laws and regulatory
programs  related  to  the   environment.   Ongoing   environmental   compliance
activities,  which  have  not  been  material,  are  charged  to  operation  and
maintenance  activities.  The Company  estimates  that the remaining cost of its
manufactured  gas  plant  ("MGP")  related   environmental  cleanup  activities,
including costs associated with the Ravenswood  Facility,  will be approximately
$128 million and has recorded a related liability for such amount.  Further,  as
of December 31, 1999,  the Company has expended a total of $15.9  million.  (See
Note 9 to the Consolidated  Financial Statements,  "Contractual  Obligations and
Contingencies".)

YEAR 2000 ISSUES

The  Company   experienced  no  significant  Year  2000  related   abnormalities
associated  with the roll over to the year 2000.  All systems  needed to deliver
gas and  electric  services to  customers,  as well as those  systems  needed to
manage daily  business  functions  performed  without  significant  malfunction.
Nevertheless,  the Company  continues to monitor systems for any unexpected Year
2000 related abnormalities.

The Company has spent a total of approximately $29.6 million to address the Year
2000  issue.  While the Year 2000  Project  is  virtually  complete,  some minor
expenses  will be incurred  for the  continued  review of systems to monitor for
Year  2000  abnormalities.  The  largest  portion  of the Year  2000  costs  was
attributable  to  the  assessment,   modification,   and  testing  of  corporate
information  technology ("IT") supported  computer software and in-house written
applications.  The  Company's  implementation  of the Year 2000  Project did not
directly  result in  delaying  any IT  projects.  The  Company's  cash flow from
operations  and cash on-hand have been  sufficient to fund the Year 2000 Project
expenditures.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The  Company and its  subsidiaries  are subject to various  risk  exposures  and
uncertainties associated with their operations. The most significant contingency
involves  the  evolution  of  the  gas  distribution   industry  toward  a  more
competitive and deregulated  environment.  Most important to the Company, is the
evolution of  regulatory  policy as it pertains to the  Company's  fixed charges
associated  with its firm gas purchase  contracts  related to its historical gas
merchant  role.  In addition,  the Company is exposed to  commodity  price risk,
interest  rate risk and, to a much less  degree,  foreign  currency  translation
risk. Set forth below is a description of these  exposures and an explanation as
to how  the  Company  and its  subsidiaries  have  managed  and,  to the  extent
possible, sought to reduce these risks.

REGULATORY ISSUES AND THE COMPETITIVE ENVIRONMENT

The Gas Industry:  The energy industry continues to undergo fundamental changes,
which may have a  significant  impact on the  future  financial  performance  of
utilities, as regulatory authorities, elected officials and customers seek lower
energy prices and broader choices.

Over the past few years,  the NYPSC has been  formulating a policy  framework to
guide the  transition  of New York  State's  gas  distribution  industry  in the
deregulated gas industry environment.  Since 1996, customers in the small-volume
market have been given the option to purchase  their gas  supplies  from sources
other than the Company's two gas utility  subsidiaries.  Large-volume  customers
had this option for a number of years prior to 1996. In addition to transporting
gas that customers  purchase from marketers,  the Company's  utilities have been
providing  billing,  meter reading and other  services for aggregate  rates that
match the distribution  charge reflected in otherwise  applicable sales rates to
supply these customers.

In November 1998, the NYPSC issued a policy  statement  setting forth its vision
for  furthering  competition  in the natural gas  industry.  Under this  vision,
regulated natural gas utilities or local  distribution  companies ("LDCs") would
plan to exit the  business of  purchasing  gas for and selling gas to  customers
(the merchant  function)  over the next three to seven years.  LDCs would remain
the operators of the gas system (the distribution  function) and the provider of
last resort of natural gas  supplies  during that period and until  alternatives
are developed.  The NYPSC's goal is to encourage  more  competition at the local
level by separating the merchant function from the distribution function.

As required by NYPSC's  policy  statement,  the Company's  two gas  distribution
subsidiaries  filed a joint  restructuring  proposal  with the NYPSC in  October
1999.  The filing  offers a  comprehensive  restructuring  plan  designed to (i)
provide a significant  impetus toward  exiting the gas supply  business and (ii)
present the NYPSC with an  opportunity  to realize  its vision of a  competitive
unbundled gas supply market for all customers within the transitional time frame
of three to seven  years.  Under the  proposal the  Company's  gas  distribution
subsidiaries  would  continue  to be the  provider  of last  resort  during  the
transition period. The restructuring plan seeks to "jump start" the migration of
the mass customer market  (especially  the residential and the small  commercial
and  industrial  markets)  from  bundled  utility  sales  service  to  unbundled
transportation service, accelerates the elimination of

                                              32

<PAGE>



regulatory cost burdens from the gas supply market, provides protections for low
income customers, and sets forth a plan to minimize potential strandable costs.

Currently,  the Company's gas distribution  subsidiaries  have contracts for the
purchase of upstream interstate  transportation,  storage and supply with annual
fixed demand charges of approximately  $280 million.  These contracts have terms
that range from one to fourteen years and the associated  demand charges through
the term of the  contracts  are  approximately  $1.6  billion.  The  Company has
estimated its strandable  costs as the costs under these  contracts in excess of
market value.  The Company has assumed that, if it were  necessary to assign the
contracts to third  parties,  the Company  could recover the market value of the
underlying assets.  Therefore, the difference between the contract costs and the
market value is the potential "strandable" costs. The Company estimates that, if
the gas  distribution  subsidiaries  continue to recover  demand charges for the
next five years,  then the estimated  potential  strandable  costs for contracts
that will not expire by 2005 and would not be needed to provide  service to firm
transportation  customers will be, on a present value basis,  approximately  $78
million.

In its  proposal,  the  Company  has  set  forth  a plan  to  recover  potential
strandable costs during the transition period. The plan includes the creation of
a price differential  between gas utility bundled service and unbundled services
available in the marketplace.  The increased  revenue  generated from this price
differential  would be retained by the Company's gas  distribution  subsidiaries
for future  application  to recover  costs  associated  with the  transition  to
competition,  including  strandable costs. In addition,  the Company  recommends
retention of certain customer refunds that otherwise would have been refunded to
customers  during  the  transition  period.  The plan  also  recommends  certain
financial  incentives and mechanisms to mitigate potential strandable costs. The
Company believes that implementation of this plan, or some variation designed to
achieve  the  same   objectives,   will  allow  both  of  its  gas  distribution
subsidiaries to fully recover their strandable costs.

The  Company  believes  that its  proposal  strikes  a balance  among  competing
stakeholder  interests in order to most  effectively make available the benefits
of the unbundled gas supply market to all  customers.  The Company  currently is
not able to determine the outcome of this proceeding and what effect, if any, it
may have on its operations.

The  Electric  Industry:  As  previously   mentioned,   the  Company's  electric
operations on Long Island are generally  governed by its service agreements with
LIPA. The agreements have terms of eight to fifteen years and generally  provide
for recovery of virtually all costs of  production,  operation and  maintenance.
Also,  since  Long  Island  is  considered  a "load  pocket",  i.e.,  there  are
insufficient  transmission  ties to permit a significant  amount of energy to be
transported into Long Island,  the Company faces minimal  competitive  pressures
associated with its electric operations on Long Island at this time.

With its  investment in the Ravenswood  Facility,  the Company also has electric
operations in New York City. The Company  currently sells the energy produced by
the  Ravenswood  Facility  through  daily and/or  hourly  bidding into the NYISO
energy markets. Further, the Company has a capacity

                                              33

<PAGE>



contract with Con Edison,  which  provides Con Edison with 100% of the available
capacity of the Ravenswood Facility.  The Company anticipates that this contract
will  expire on April 30,  2000,  at which time the  available  capacity  of the
Ravenswood  Facility  will be bid into on the auction  process  conducted by the
NYISO. New York City local  reliability  rules currently require that 80% of the
electric  capacity  needs  of New  York  City  is to be  provided  by  "in-city"
generators.  At this time,  there is a current  shortage of in-city capacity and
the  Company,  therefore,  anticipates  that it can  sell  the  capacity  of the
Ravenswood  Facility at a level  approaching  the FERC  mandated  price cap. The
Company expects that the current local  reliability  rules will remain in effect
at least through 2000. However, should new, more efficient electric power plants
be built in New York City  and/or the  requirement  that 80% of in-city  load be
served by in-city  generators  be modified,  capacity  and energy sales  volumes
could be adversely affected.  The Company can not predict,  however,  when or if
new  power  plants  will  be  built  or the  nature  of  future  New  York  City
requirements.

DERIVATIVE FINANCIAL INSTRUMENTS

As previously mentioned,  and more fully detailed in Note 10 to the Consolidated
Financial  Statements,  "Hedging,  Derivative  Financial  Instruments  and  Fair
Values",  the Company  hedges a portion of its exposure to commodity  price risk
and interest rate risk. All of the Company's derivative  financial  instruments,
except for certain  interest rate swaps,  are and will continue to be classified
as  cash-flow  hedges.  As a result,  implementation  of  Statement of Financial
Accounting  Standards ("SFAS") No. 133,  "Accounting for Derivative  Instruments
and Hedging  Activities" when adopted, is not expected to have a material effect
on  the  Company's  net  income,   but  could  have  a  significant   effect  on
comprehensive  income  because  of  fluctuations  in  the  market  value  of the
derivatives  employed for hedging  certain risks.  Under SFAS No. 133,  periodic
changes  in market  value are  recorded  as  comprehensive  income,  subject  to
effectiveness,  and  then  included  in  net  income  to  match  the  underlying
transactions.

Commodity   Hedges  and  Financial   Instruments:   The  Company's  gas  utility
subsidiaries, marketing, and gas exploration and production subsidiaries employ,
from time to time, derivative financial instruments, such as natural gas and oil
futures,  options and swaps,  for the purpose of hedging  exposure to  commodity
price risk.

Whenever hedge positions are in effect,  the Company's  subsidiaries are exposed
to credit risk in the event of  nonperformance  by counter parties to derivative
contracts,  as well as nonperformance by the counter parties of the transactions
against which they are hedged. The Company believes that the credit risk related
to the futures,  options and swap instruments is no greater than that associated
with the  primary  commodity  contracts  which  they  hedge,  as the  instrument
contracts  are with major  investment  grade  financial  institutions,  and that
reduction of the exposure to price risk lowers the  Company's  overall  business
risk.

Interest Rate Hedges:  The Company  continually  monitors the cost  relationship
between  fixed and variable  rate debt.  In line with its  objective to minimize
capital costs, the Company periodically enters into hedging transactions through
interest rate swaps that effectively convert the terms of the

                                              34

<PAGE>



underlying debt  obligations from fixed to variable and/or variable to fixed. In
addition,  the Company also enters into hedges to fix the rate on commitments to
issue debt securities  prior to the actual  financing.  Swap agreements are only
entered into with creditworthy counter parties.

FOREIGN CURRENCY FLUCTUATIONS

The  Company  follows  the  principles  of  SFAS  No.  52,   "Foreign   Currency
Translation"  for recording its  investments in foreign  affiliates.  Due to the
Company's  purchases of certain Canadian interests and its continued  activities
in Northern  Ireland,  the Company's  investment in foreign  affiliates has been
growing.  At December 31, 1999, the Company's net assets in these affiliates was
approximately  $251.0 million and at December 31, 1999, the accumulated  foreign
currency translation  adjustment was $7.7 million favorable.  (See Note 1 to the
Consolidated   Financial   Statements,   "Summary  of   Significant   Accounting
Policies".)

For  additional   information  concerning  market  risk,  see  Note  10  to  the
Consolidated Financial Statements,  "Hedging,  Derivative Financial Instruments,
and Fair Values".

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

FINANCIAL STATEMENT RESPONSIBILITY

The Consolidated  Financial  Statements of the Company and its subsidiaries were
prepared  by  management  in  conformity  with  generally  accepted   accounting
principles.

The  Company's  system of internal  controls  is designed to provide  reasonable
assurance  that assets are  safeguarded  and that  transactions  are executed in
accordance with management's  authorizations  and recorded to permit preparation
of financial statements that present fairly the financial position and operating
results of the Company.  The Company's  internal  auditors evaluate and test the
system of internal  controls.  The Company's Vice President and General  Auditor
reports  directly to the Audit  Committee  of the Board of  Directors,  which is
composed entirely of outside  directors.  The Audit Committee meets periodically
with management,  the Vice President and General Auditor and Arthur Andersen LLP
to review and discuss internal accounting  controls,  audit results,  accounting
principles and practices and financial reporting matters.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

A.  ORGANIZATION OF THE COMPANY

KeySpan Corporation, d/b/a KeySpan Energy (the "Company" or "KeySpan Energy") is
a holding  company  operating  two  utilities  that  distribute  natural  gas to
approximately 1.6 million customers in New York City and on Long Island,  making
it the fourth  largest  gas-distribution  company in the  United  States.  Other
KeySpan  Energy  companies  market a  portfolio  of gas-  marketing  and energy-
related services in the Northeast, own and operate electric-generation plants in
New York City and on Long Island, and provide operating and customer services to
approximately 1.1 million electric  customers of the Long Island Power Authority
("LIPA").  The Company's other energy  activities  include:  gas exploration and
production, primarily through The Houston Exploration Company ("THEC"); domestic
pipelines and storage; and international activities, including gas processing in
Canada, and gas pipelines and local distribution in Northern Ireland.  (See Note
2, "Business Segments" for additional information on each operating segment.)

The Company is the successor to Long Island  Lighting  Company  ("LILCO"),  as a
result of a  transaction  with LIPA (the "LIPA  Transaction")  and following the
acquisition (the "KeySpan  Acquisition") of KeySpan Energy Corporation  ("KSE").
On May 28, 1998, the Company completed two business  combinations as a result of
which  it  (i)  became  the  successor  operator  of  the  non-nuclear  electric
generating  facilities,  gas  distribution  operations and common plant formerly
owned by LILCO and entered  into  long-term  service  agreements  to operate the
electric transmission and distribution ("T&D") system acquired by LIPA; and (ii)
acquired KSE, the parent  company of The Brooklyn  Union Gas Company  ("Brooklyn
Union").  (See Note 14, "Sale of LILCO  Assets,  Acquisition  of KeySpan  Energy
Corporation and Transfer of Assets and Liabilities to the Company".)

B.  BASIS OF PRESENTATION

The Consolidated  Financial  Statements presented herein reflect the accounts of
the Company and its subsidiaries.  Most of the Company's  subsidiaries are fully
consolidated  in the  financial  information  presented,  except for  subsidiary
investments in the Energy Related  Investment segment which are accounted for on
the equity method as the Company does not have a controlling  voting interest or
otherwise  have  control  over  the  management  of  investee   companies.   All
significant intercompany transactions have been eliminated.

Certain reclassifications were made to conform prior period financial statements
with the current period financial statement presentation.

The financial  statements  presented  herein include the year ended December 31,
1999, the nine

                                        1

<PAGE>



month period April 1, 1998 through December 31, 1998 (the "Transition  Period"),
and the fiscal year ended March 31,  1998.  For  financial  reporting  purposes,
LILCO  is  deemed  the  acquiring  company  pursuant  to a  purchase  accounting
transaction, in which KSE was acquired.  Consequently,  financial results of the
Company prior to May 29, 1998 reflect those of LILCO only. Since the acquisition
of  KSE  was  accounted  for  as a  purchase,  related  accounting  adjustments,
including  goodwill,  have been  reflected in the financial  statements  herein.
Further,  in September 1998, the Company changed its fiscal year end to December
31.

The preparation of financial  statements in conformity  with generally  accepted
accounting principles requires management to make estimates and assumptions that
affect  the  reported  amounts  of assets  and  liabilities  and  disclosure  of
contingent  assets and  liabilities at the date of the financial  statements and
the  reported  amounts of revenues  and expenses  during the  reporting  period.
Actual results could differ from those estimates.

C.  ACCOUNTING FOR THE EFFECTS OF RATE REGULATION

The  Company's  accounting  records for its two  regulated gas utilities and its
generation  subsidiaries are maintained in accordance with the Uniform System of
Accounts  prescribed by the Public  Service  Commission of the State of New York
("NYPSC") and the Federal Energy Regulatory  Commission ("FERC"),  respectively.
However, the Company's electric generation subsidiaries are not subject to NYPSC
rate  regulation,  but  they  are  subject  to FERC  regulation.  The  Company's
financial  statements  reflect  the  ratemaking  policies  and  actions of these
regulators in conformity  with  generally  accepted  accounting  principles  for
rate-regulated enterprises.

The  Company's   two  regulated  gas  utilities  and  its  electric   generation
subsidiaries 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 ability of regulators,  through the
ratemaking process, to create future economic benefits and obligations affecting
rate-regulated companies. Accordingly, the Company records these future economic
benefits  and  obligations  as  regulatory  assets and  regulatory  liabilities,
respectively.



                                        2

The following table presents the Company's net regulatory assets at December 31,
1999 and December 31, 1998.

                                                   (IN THOUSANDS OF DOLLARS)

                                           December 31, 1999  December 31, 1998
- ------------------------------------------ -------------------- ---------------
Regulatory Assets
   Regulatory tax asset                    $             65,462 $       68,780
   Property taxes                                        40,434         12,792
   Environmental costs                                   95,627        100,505
   Postretirement benefits other than pensions           48,553         51,788
   Costs associated with the KeySpan Acquisition         69,091         45,659
Total Regulatory Assets                    $            319,167 $      279,524
Regulatory Liability                                     26,618         27,854
Total Net Regulatory Assets                $            292,549 $      251,670
========================================== ==================== ================

The  regulatory  assets  above are not  included  in the  Company's  rate  base.
However,  the Company  records  carrying  charges on the  property tax and costs
associated  with the KeySpan  Acquisition  deferrals.  The Company  also records
carrying charges on its regulatory  liability.  The remaining  regulatory assets
represent,  primarily,  costs for which expenditures have not yet been made, and
therefore, carrying charges are not recorded. The Company anticipates recovering
these costs in its gas rates  concurrently  with future  cash  expenditures.  If
recovery is not concurrent with the cash  expenditures,  the Company will record
the appropriate level of carrying charges.

The  Company  estimates  that full  recovery of its  regulatory  assets will not
exceed 15 years,  except for the tax  regulatory  asset which will be  recovered
over the estimated lives of certain utility property.
Rate  regulation is undergoing  significant  change as regulators  and customers
seek lower  prices for  utility  service and greater  competition  among  energy
service  providers.  In the event  that  regulation  significantly  changes  the
opportunity for the Company to recover its costs in the future, all or a portion
of the Company's  regulated  operations  may no longer meet the criteria for the
application  of SFAS No. 71. In that event,  a write-down of all or a portion of
the Company's  existing  regulatory  assets and liabilities could result. If the
Company had been unable to  continue to apply the  provisions  of SFAS No. 71 at
December 31, 1999, the Company would have applied the provisions of SFAS No. 101
"Regulated  Enterprises - Accounting for the  Discontinuation  of Application of
FASB  Statement  No. 71". The Company  estimates  that the  write-off of its net
regulatory  asset  could  result in a charge to net income of $190.2  million or
$1.37 per share after-tax,  which would be classified as an extraordinary  item.
In management's opinion, the Company's regulated subsidiaries will be subject to
SFAS No. 71 for the foreseeable future.

As part of the LIPA  Transaction,  the Company has entered into various  service
agreements  with LIPA that  prescribe  the  conduct  of the  Company's  electric
operations. These agreements allow the

                                        3

<PAGE>



Company to recover its costs incurred to service the agreements and  potentially
allow the  Company to earn a certain  level of profit.  The  Company's  electric
operations,  other than the generation function which is FERC regulated,  are no
longer  subject  to rate  regulation  and,  as a result,  the  Company no longer
applies SFAS No. 71 to certain of its electric operations.

D.  REVENUES

Utility gas  customers  are billed  monthly  and  bi-monthly  on a cycle  basis.
Revenues  include  unbilled  amounts  related  to the  estimated  gas usage that
occurred from the most recent meter reading to the end of each month.

The cost of gas used is  recovered  when  billed to firm  customers  through the
operation of the gas adjustment clause ("GAC") included in utility tariffs.  The
GAC provision requires an annual reconciliation of recoverable gas costs and GAC
revenues.  Any  difference is deferred  pending  recovery from or refund to firm
customers during a subsequent  twelve-month  period.  Further, net revenues from
tariff  gas  balancing   services,   off-system  sales  and  certain   on-system
interruptible  sales are refunded to firm customers  subject to certain  sharing
provisions.

The gas utility tariffs contain weather  normalization  adjustments that largely
offset shortfalls or excesses of firm net revenues  (revenues less gas costs and
revenue taxes) during a heating season due to variations from normal weather.

Electric revenues since the LIPA Transaction are primarily derived from billings
to  LIPA  for  management  of  LIPA's  T&D  system,  electric  generation,   and
procurement of fuel. In addition,  electric  revenues also include revenues from
the Company's  investment in the 2,168 megawatt  Ravenswood  electric generation
facility  ("Ravenswood  Facility") which the Company acquired in June 1999. (See
Note 9,  "Contractual  Obligations and  Contingencies"  for a description of the
Ravenswood transaction.)

The  agreements  with LIPA include  provisions  for the Company to earn,  in the
aggregate,  approximately  $11.5  million per year (plus up to an  additional $5
million per year if certain  cost  savings are  achieved)  in annual  management
service  fees  from  LIPA for the  management  of the LIPA  T&D  system  and the
management of all aspects of fuel and power supply.  Costs in excess of budgeted
levels are assumed by the Company up to $15 million,  while cost  reductions  in
excess of $5 million from budgeted levels are shared with LIPA. These agreements
also contain  certain non- cost  incentive  and penalty  provisions  which could
impact  earnings.  Billings  associated  with  generation  capacity are based on
pre-determined  levels  of supply to be  dispatched  to LIPA on a yearly  basis.
Rates  charged to LIPA  include  fixed and  variable  components.  The  variable
component is billed to LIPA on a monthly basis and is dependent on the amount of
megawatt  hours  dispatched.  In  addition,  billings  related to  transmission,
distribution  and delivery  services are based, in part, on negotiated  budgeted
levels.

The  Company  currently  sells the energy  produced by the  Ravenswood  Facility
through daily and/or

                                        4

<PAGE>



hourly bidding into the New York  Independent  System Operator  ("NYISO") energy
markets.  Revenues are recorded  when the energy is sold to the NYISO.  Further,
the Company currently has a capacity  contract with Consolidated  Edison Company
of New York,  Inc.  ("Con  Edison"),  which provides Con Edison with 100% of the
available  capacity of the Ravenswood  Facility.  Capacity charges are billed to
Con  Edison on a monthly  fixed-fee  basis in  accordance  with the terms of the
capacity  contract.  The Company  anticipates  that this contract will expire on
April 30, 2000, at which time the available capacity of the Ravenswood  Facility
will be bid into on the auction process conducted by the NYISO.

Prior  to the  LIPA  Transaction,  electric  revenues  were  comprised  of cycle
billings  rendered to residential,  commercial and industrial  customers and the
accrual of electric  revenues for services  rendered to customers  not billed at
month-end.   In  addition,   LILCO's  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. Moreover,  LILCO's
electric tariff  included a fuel cost  adjustment  ("FCA") clause which provided
for the  disposition  of the  difference  between actual fuel costs and the fuel
costs allowed in base tariff rates.  LILCO deferred these  differences to future
periods for recovery from or refund 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.

E.  UTILITY PROPERTY - DEPRECIATION AND MAINTENANCE

Utility gas property is stated at original cost of construction,  which includes
allocations  of  overheads,  including  taxes,  and an allowance  for funds used
during construction.  As part of the LIPA Transaction,  all T&D assets were sold
to LIPA,  and as a result,  all costs  incurred  under the  Management  Services
Agreement in  connection  with the  Company's  provision of services for the T&D
system subsequent to May 28, 1998 are expensed and charged to LIPA. As a result,
electric  depreciation now consists of depreciation of the non-nuclear  electric
generating facilities formerly owned by LILCO and the Ravenswood Facility.

Depreciation  is  provided on a  straight-line  basis in amounts  equivalent  to
composite rates on average depreciable  property.  The cost of property retired,
plus the cost of removal less salvage,  is charged to accumulated  depreciation.
The cost of repair and minor  replacement  and renewal of property is charged to
maintenance expense. The composite rates on average depreciable property were as
follows:

               Period                              Electric      Gas
               -------                             --------      ---
        Year Ended December 31, 1999               3.56%         2.85%
        Nine Months Ended December 31, 1998        2.54%         2.07%
        Fiscal Year Ended March 31, 1998           3.20%         2.06%




                                        5

F.  GAS EXPLORATION AND PRODUCTION PROPERTY - DEPLETION

The full cost method of  accounting is used for  investments  in natural gas and
oil properties.  Under this method,  all costs of  acquisition,  exploration and
development  of natural gas and oil reserves are  capitalized  into a "full cost
pool" as  incurred,  and  properties  in the pool are  depleted  and  charged to
operations  using the  unit-of-production  method  based on the ratio of current
production to total proved natural gas and oil reserves. To the extent that such
capitalized costs (net of accumulated  depletion) less deferred taxes exceed the
present  value  (using a 10% discount  rate) of estimated  future net cash flows
from proved  natural gas and oil reserves and the lower of cost or fair value of
unproved  properties,  such  excess  costs  are  charged  to  operations.  If  a
write-down  is  required,  it would result in a charge to earnings but would not
have an impact on cash flows from  operating  activities.  Once  incurred,  such
impairment  of gas  properties  is not  reversible  at a later  date even if gas
prices  increase.  In December  1998,  THEC, the Company's 64% owned gas and oil
exploration and production subsidiary, recorded a $130 million write-down to its
investment  in its proved gas reserves,  which is reflected in the  accompanying
financial statements

As of December 31, 1999, THEC estimates, using prices in effect as of such date,
that the ceiling  limitation  imposed under full cost accounting  rules exceeded
actual capitalized costs.

Provisions for depreciation of all other non-utility  property are computed on a
straight line basis over useful lives of three to ten years.

G.  HEDGING AND DERIVATIVE FINANCIAL INSTRUMENTS

Commodity  Derivatives:  The Company's utility,  marketing subsidiaries and THEC
employ, from time to time, derivative financial instruments to hedge exposure in
cash  flows due to  fluctuations  in the price of  natural  gas.  The  Company's
hedging  strategies meet the criteria for hedge accounting  treatment under SFAS
No. 80,  "Accounting for Futures  Contracts."  Accordingly,  gains and losses on
these  instruments  are  recognized  concurrently  with the  recognition  of the
related physical transactions.

The subsidiaries regularly assess the relationship between natural gas commodity
prices in "cash" and futures  markets.  The correlation  between prices in these
markets  has been  within a range  generally  deemed  to be  acceptable.  If the
correlation were not to remain in an acceptable  range,  the subsidiaries  would
account for financial instrument positions as trading activities.

Interest  Rate   Derivatives:   The  Company   continually   assesses  the  cost
relationship between fixed and variable rate debt. In line with its objective to
minimize   capital  costs,   the  Company   periodically   enters  into  hedging
transactions  that effectively  convert the terms of underlying debt obligations
from fixed to  variable  and/or  variable  to fixed.  Monthly  payments  made or
received are  recognized as an adjustment  to interest  expense as incurred.  In
addition,  the Company also enters into hedges to fix the rate on commitments to
issue debt securities prior to the actual financing.

                                        6

<PAGE>



Hedging  transactions  that  effectively  convert the terms of  underlying  debt
obligations  from fixed to  variable  and/or  variable  to fixed are  considered
fair-value hedges. All of the Company's other derivative  financial  instruments
are,  and will  continue to be  classified  as  cash-flow  hedges.  As a result,
implementation  of SFAS No. 133,  "Accounting  for  Derivative  Instruments  and
Hedging  Activities," when adopted, is not expected to have a material effect on
the Company's net income,  but could have a significant  effect on comprehensive
income because of fluctuations  in the market value of the derivatives  employed
for hedging certain risks.  Under SFAS No. 133, periodic changes in market value
are  recorded  as  comprehensive  income,  subject  to  effectiveness,  and then
included in net income to match the underlying transactions.

H.  EQUITY INVESTMENTS

Certain  subsidiaries  own as  their  principal  assets  investments,  including
goodwill,  representing  ownership  interests  of 50% or less in  energy-related
businesses that are accounted for under the equity method.

I.  INCOME TAX

In accordance with SFAS No. 109, "Accounting for Income Taxes" and NYPSC policy,
certain of the Company's  regulated  subsidiaries  record a regulatory asset for
the net  cumulative  effect of having to provide  deferred  income  taxes on all
differences  between tax and book bases of assets and liabilities at the current
tax rate which have not yet been included in rates to customers.  Investment tax
credits, which were available prior to the Tax Reform Act of 1986, were deferred
and are amortized as a reduction of income tax over the  estimated  lives of the
related property.

J.  SUBSIDIARY COMMON STOCK ISSUANCES TO THIRD PARTIES

The Company  follows an accounting  policy of income  statement  recognition for
parent company gains or losses from issuances of common stock by subsidiaries.

K.  FOREIGN CURRENCY TRANSLATION

The  Company  follows  the  principles  of  SFAS  No.  52,   "Foreign   Currency
Translation,"  for recording its investments in foreign  affiliates.  Under this
statement,  all  elements of  financial  statements  are  translated  by using a
current exchange rate.  Translation  adjustments result from changes in exchange
rates from one reporting  period to another.  At December 31, 1999,  the foreign
currency  translation  adjustment was included in comprehensive  income and as a
separate component of shareholders' equity.

L.  GOODWILL

At December 31, 1999, the Company has recorded  goodwill in the amount of $255.8
million,  representing the excess of acquisition cost over the fair value of net
assets acquired. Goodwill is

                                        7

<PAGE>



amortized  over  15 to  40  years.  The  Company's  recorded  goodwill,  net  of
accumulated amortizations,  consists of approximately $164.1 million relating to
the  KeySpan   Acquisition  and  approximately  $91.7  million  related  to  the
acquisitions  of  energy-related  services  companies  and to certain  ownership
interests of 50% or less in  energy-related  investments in Northern Ireland and
Canada which are accounted for under the equity method.

M.  RECENT ACCOUNTING PRONOUNCEMENTS

In June 1999, the Financial  Accounting Standards Board ("FASB") issued SFAS No.
137, "Accounting for Derivative Instruments and Hedging Activities - Deferral of
the Effective  Date of SFAS No. 133." SFAS No. 137 defers the effective  date of
SFAS No. 133 to fiscal years  beginning  after July 15,  2000.  The Company will
therefore, adopt SFAS No. 133 in the first quarter of fiscal year 2001. SFAS No.
133 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.  As previously  mentioned,  all of the
Company's  derivative  financial  instruments,  except for certain interest rate
swaps, are and will continue to be classified as cash-flow  hedges. As a result,
implementation of SFAS No. 133 when adopted,  is not expected to have a material
effect on the  Company's  net  income,  but could have a  significant  effect on
comprehensive  income  because  of  fluctuations  in  the  market  value  of the
derivatives  employed for hedging  certain risks.  Under SFAS No. 133,  periodic
changes  in market  value are  recorded  as  comprehensive  income,  subject  to
effectiveness,  and  then  included  in  net  income  to  match  the  underlying
transactions.


NOTE 2. BUSINESS SEGMENTS

The Company has six reportable  segments:  Gas Distribution,  Electric Services,
Gas  Exploration  and  Production,   Energy  Related  Services,  Energy  Related
Investments and Other.

The Gas  Distribution  segment  consists of the Company's  two gas  distribution
subsidiaries.  Brooklyn Union provides gas distribution services to customers in
the New York City boroughs of Brooklyn,  Queens and Staten  Island,  and KeySpan
Gas East d/b/a Brooklyn Union of Long Island  ("Brooklyn  Union of Long Island")
provides gas  distribution  services to customers in the Long Island counties of
Nassau and Suffolk and the Rockaway Peninsula of Queens County.

The Electric Services segment consists of Company  subsidiaries that operate the
electric T&D system owned by LIPA, own and sell capacity and energy to LIPA from
the  Company's  generating  facilities  located on Long  Island and manage  fuel
supplies  for LIPA to fuel  the  Company's  Long  Island  generating  facilities
through  long-term  service  contracts  that have terms that range from eight to
fifteen years, as well as, Company  subsidiaries that own, lease and operate the
2,168 megawatt  Ravenswood  Facility,  located in Long Island City, Queens. (See
Note 9,  "Contractual  Obligations and  Contingencies"  for a description of the
Ravenswood  transaction.)  Currently,  the Company's primary electric generation
customers are LIPA and Con Edison.

The Gas Exploration and Production segment is engaged in gas and oil exploration
and production,  and the development and acquisition of domestic natural gas and
oil  properties.  This segment  consists of the Company's 64% equity interest in
THEC, an independent natural gas and oil exploration company, as well as KeySpan
Exploration and Production LLC, the Company's wholly owned subsidiary engaged in
a joint  venture  with THEC.  In  September  1999,  the Company and THEC jointly
announced  their intention to begin a process to review  strategic  alternatives
for THEC.  The  process  included an  assessment  of the role of THEC within the
Company's  strategic  plans,  including the possible sale of all or a portion of
THEC by the Company.  After completing the review, the Company concluded that it
would retain its equity interest in THEC.  Further,  under a pre-existing credit
arrangement,  approximately $80 million in debt owed by THEC to the Company will
be converted  into common equity on April 1, 2000.  The Company's  common equity
ownership  interest  in THEC  will  increase  to  approximately  70%  upon  such
conversion.  The Company will commit  approximately  $25 million to the drilling
program with THEC in 2000, which may be terminated,  upon notice,  at the option
of either party.

The Company's Energy Related Services segment primarily  includes KeySpan Energy
Management  Inc.  ("KEM"),   KeySpan  Energy  Services  Inc.  ("KES"),   KeySpan
Communications  Corporation,  KeySpan Energy  Solutions,  LLC ("KESol"),  Fritze
KeySpan,  LLC ("Fritze"),  and Delta KeySpan Inc.  ("Delta").  KEM owns, designs
and/or  operates  energy systems for  commercial  and  industrial  customers and
provides  energy-related  services to clients located  primarily  within the New
York City  metropolitan  area.  KES markets gas and  electricity,  and  arranges
transportation  and related  services,  largely to retail  customers,  including
those  served  by the  Company's  two  gas  distribution  subsidiaries.  KeySpan
Communications  Corporation  owns a fiber optic  network on Long Island.  KESol,
Fritze  and  Delta  provide  various  appliance,  heating,  ventilation  and air
conditioning  ("HVAC")  services  to  customers  within  the  Company's  service
territory,  New Jersey and Rhode Island.  KESol was  established  in April 1998,
Fritze was acquired in November  1998 and Delta was acquired in September  1999.
Further, in February 2000, the Company acquired three additional companies.  The
newly acquired companies include, an engineering-consulting firm, a plumbing and
mechanical  contracting firm, and a firm specializing in mechanical  contracting
and HVAC.

Subsidiaries  in the Energy  Related  Investments  segment  include a 20% equity
interest  in the  Iroquois  Gas  Transmission  System LP; a 50%  interest in the
Premier  Transco  Pipeline and a 24.5% interest in Phoenix  Natural Gas, both in
Northern  Ireland;  and investments in certain  midstream  natural gas assets in
Western  Canada owned jointly with Gulf Canada  Resources  Limited,  through the
Gulf Midstream Services  Partnership  ("GMS").  These subsidiaries are accounted
for under the equity method since the Company's  ownership  interests are 50% or
less.  Accordingly,  equity income from these  investments is reflected in other
income and (deductions) in the Consolidated Income Statement.

The Other segment represents primarily,  preferred stock dividends,  unallocated
administrative   expenses  and  interest   income   earned  on  temporary   cash
investments.  In 1999, all preferred stock dividends were allocated to the Other
segment whereas,  prior to the LIPA Transaction,  preferred stock dividends were
allocated to gas and electric operations.

The accounting  policies of the segments are the same as those  described in the
summary of significant  accounting  policies.  The Company's reportable segments
are  strategic  business  units  that are  managed  separately  because of their
different  operating  and  regulatory   environments.   The  reportable  segment
information is as follows:

NOTE 3. INCOME TAX

The Company  will file  consolidated  federal  and state  income tax returns for
calendar  year  1999.  A tax  sharing  agreement  between  the  Company  and its
subsidiaries  provides for the allocation of a realized tax liability or benefit
based upon separate return  contributions of each subsidiary to the consolidated
taxable income or loss in the consolidated income tax returns.

In 1998,  the Company  incurred  tax net  operating  losses  ("NOL") for federal
purposes  of $148.9  million and for state  purposes  of $211.0  million for the
period May 29, 1998 through  December 31, 1998, which can be carried forward for
twenty years or until 2017.  In accordance  with SFAS No. 109 - "Accounting  For
Income  Taxes," the Company  believed  that it was more likely than not that the
tax benefits of these losses would be realized.  Therefore, in 1998 deferred tax
assets and related tax benefits for the tax effect of the NOL carryforwards were
recorded by the Company ($52.1 million for federal income tax purposes and $19.0
million for state income tax purposes).

The Company  estimates that the benefits  associated with the NOL  carryforwards
from 1998, $57.4 million ($52.1 million for federal income tax purposes and $5.3
million for state  income tax  purposes),  will be realized in its  consolidated
1999 federal and state income tax returns.

                                       13

<PAGE>



Accordingly,  the NOL benefits have been applied in the 1999 current federal and
state tax provisions.

Income tax  expense  (benefit)  is  reflected  as  follows  in the  Consolidated
Statement of Income:

        necessary to account for the difference  between the carryover  basis of
        the  Transferred  Assets for  financial  reporting  purposes and the new
        increased  tax basis and (b)  certain  credits for  financial  reporting
        purposes,   including   tax  benefits   recognized  on  the  funding  of
        postretirement  benefits,  partially  offset by income taxes  associated
        with the sale of the  Transferred  Assets to the  Company  by LIPA which
        taxes were paid by the Company.


In 1990 and 1992,  LILCO  received an Internal  Revenue  Service  Agents' Report
disallowing  certain  deductions  and  credits  claimed by LILCO on its  federal
income tax returns for the years 1981 through  1989. A settlement  resolving all
audit issues was reached  between LILCO and the Internal  Revenue Service in May
1998.  The  settlement  required the payment of taxes and interest of $9 million
and $35  million,  respectively,  which the Company  made in May 1998.  Adequate
reserves to cover such taxes and interest were previously provided.

NOTE 4.  POSTRETIREMENT BENEFITS

PENSION PLANS: The following information represents consolidated results for the
Company and its subsidiaries  (Brooklyn Union, Brooklyn Union of Long Island and
the former LILCO),  whose  noncontributory  defined  benefit pension plans cover
substantially  all  employees.  Benefits  are  based  on years  of  service  and
compensation. Funding for pensions is in accordance with requirements of federal
law and regulations. Prior to the KeySpan Acquisition, pension benefits had been
managed separately by the Company's regulated subsidiaries,  which were the only
subsidiaries  with defined benefit plans.  The Company is currently  integrating
its plans and allocations to individual business segments.

The amounts  presented are consolidated for periods  subsequent to May 28, 1998.
Prior to that date the  amounts  pertain  solely to the plan of LILCO.  Brooklyn
Union of Long  Island is  subject to certain  deferral  accounting  requirements
mandated by the NYPSC for pension costs and other postretirement benefit costs.

The calculation of net periodic pension cost follows:

INFORMATION ON THE LILCO SUPPLEMENTAL PLAN
The  Supplemental  Plan in effect  prior to May 28, 1998  provided  supplemental
death and  retirement  benefits for officers  and other key  executives  without
contribution from such employees. The Supplemental Plan was a non-qualified plan
under the Internal Revenue Code of 1986, as amended (the "Code"). For the fiscal
year ended March 31,  1998,  a charge of $31 million  was  recorded  relating to
certain  benefits earned by former officers of LILCO relating to the termination
of their annuity  benefits earned through the  supplemental  retirement plan and
other executive retirement benefits.  This charge, which was borne by LILCO, and
not  recovered  from  ratepayers,  resulted from  provisions  in the  employment
contracts of LILCO officers.

OTHER  POSTRETIREMENT  BENEFITS:  RETIREE  HEALTH CARE AND LIFE  INSURANCE:  The
following  information  represents  consolidated results for the Company and its
subsidiaries  (Brooklyn  Union,  Brooklyn  Union of Long  Island  and the former
LILCO) who sponsor noncontributory defined benefit plans covering certain health
care and life  insurance  benefits for retired  employees.  The Company has been
funding a portion  of future  benefits  over  employees'  active  service  lives
through   Voluntary   Employee   Beneficiary    Association   ("VEBA")   trusts.
Contributions  to  VEBA  trusts  are  tax  deductible,  subject  to  limitations
contained in the Code.  Prior to the KeySpan  Acquisition  other  postretirement
benefits had been managed  separately by the Company's  regulated  subsidiaries,
which were the only  subsidiaries  with defined  benefit  plans.  The Company is
currently integrating its plans and allocations to individual business segments.

The amounts presented herein are consolidated for periods  subsequent to May 28,
1998. Prior to that date the amounts pertain solely to the plan of LILCO.

Net  periodic   other   postretirement   benefit  cost  included  the  following

increase in the health care cost trend rate would have the effect of  increasing
the  accumulated  postretirement  benefit  obligation as of December 31, 1999 by
$80.9  million and the net periodic  health care expense by $8.1  million.  A 1%
decrease in the health care cost trend rate would have the effect of  decreasing
the  accumulated  postretirement  benefit  obligation as of December 31, 1999 by
$66.6 million and the net periodic health care expense by $6.7 million.

In 1993,  LILCO adopted the provisions of SFAS No. 106,  "Employer's  Accounting
for  Postretirement  Benefits Other Than  Pensions," and recorded an accumulated
postretirement  benefit obligation and a corresponding  regulatory asset of $376
million.  LIPA will  reimburse the Company for costs  related to  postretirement
benefits of the electric  business unit  employees,  therefore,  the Company has
reclassified the regulatory asset for  postretirement  benefits  associated with
electric business unit employees to a deferred asset.

In 1994, LILCO established VEBA trusts for union and non-union employees for the
funding of costs collected in rates for postretirement  benefits. For the fiscal
year ended March 31,  1998,  the trusts were funded with a  contribution  of $21
million. In May 1998, an additional $250 million was funded into the trusts.

NOTE 5. CAPITAL STOCK

COMMON STOCK:  Currently the Company has 450,000,000 shares of authorized common
stock.  In 1998, the Company  initiated a program to repurchase a portion of its
outstanding  common  stock on the open  market.  As of December  31,  1999,  the
Company had  repurchased  25 million  common shares for $723.0  million.  During
1999,  the Company  purchased  1.9 million  shares for $52.5 million on the open
market for the  dividend  reinvestment  feature  of its  Investor  Program,  the
Employee Stock Discount  Purchase Plan for Employees,  and the Employee  Savings
Plan.

PREFERRED  STOCK: The Company has the authority to issue  100,000,000  shares of
preferred  stock  with  the  following  classifications:  16,000,000  shares  of
preferred stock,  par value $25 per share;  1,000,000 shares of preferred stock,
par value $100 per share;  and 83,000,000  shares of preferred  stock, par value
$.01 per share.

At December 31, 1999,  14,520,000  redeemable  shares of 7.95%  Preferred  Stock
Series AA par value  $25 was  outstanding  totaling  $363  million,  which has a
mandatory  redemption  requirement on June 1, 2000. The Company also has 553,000
shares  outstanding of 7.07%  Preferred  Stock Series B par value $100;  197,000
shares  outstanding of 7.17% Preferred Stock Series C par value $100; and 93,390
shares  outstanding  of 6%  Preferred  Stock  Series A par  value  $100,  in the
aggregate totaling $84.3 million.

NOTE 6.  NONQUALIFIED STOCK OPTIONS

At December 31, 1999, the Company had  stock-based  compensation  plans that are
described below. Moreover,  under a separate plan, THEC has issued approximately
2.4 million stock options to key THEC employees.  The Company and THEC apply APB
Opinion  25,   "Accounting   for  Stock  Issued  to   Employees,"   and  related
Interpretations in accounting for their plans. Accordingly, no compensation cost
has been  recognized  for these fixed  stock  option  plans in the  Consolidated
Financial  Statements  since the exercise prices and market values were equal on
the grant dates. Had compensation  cost for these plans been determined based on
the fair value at the grant  dates for awards  under the plans  consistent  with
SFAS No. 123,  "Accounting  for  Stock-Based  Compensation,"  the  Company's net
income and earnings per share would have been decreased to the proforma  amounts
indicated below:

The weighted  average fair value of grants issued in 1999 was $3.65.  All grants
are  estimated on the date of the grant using the  Black-Scholes  option-pricing
model. The following weighted average assumptions were used for grants issued in
1999: dividend yield of 6.58%; expected volatility of 23.43%; risk free interest
rate of 5.72%;  and expected  lives of 6 years.  The weighted  average  exercise
price is $27.58 for the 1999 grants. There were no grants issued in 1998.

Prior to the KeySpan Acquisition, KSE had reserved for issuance 1,500,000 shares
of  nonqualified  stock  options  and had issued  426,000,  363,500  and 202,800
nonqualified stock options in November 1997, 1996 and 1995, respectively.  Under
the terms of the Merger  Agreement,  all options vested upon consummation of the
KeySpan Acquisition.

NOTE 7. LONG-TERM DEBT

GAS FACILITIES REVENUE BONDS:  Brooklyn Union can issue tax-exempt bonds through
the New York State Energy Research and Development Authority. Whenever bonds are
issued for new gas  facilities  projects,  proceeds  are  deposited in trust and
subsequently withdrawn to finance qualified  expenditures.  There are no sinking
fund  requirements  on any of the Company's Gas  Facilities  Revenue  Bonds.  At
December 31, 1999,  Brooklyn Union had $648.5 million of Gas Facilities  Revenue
Bonds outstanding. The interest rate on the variable rate series due December 1,
2020 is reset weekly and ranged from 1.97% to 5.35%  through  December 31, 1999,
at which time the average rate was 5.35%. At January 14, 2000, the interest rate
on the variable  rate series due December 1, 2020 was changed to an auction rate
with a standard auction period of seven days.

In November  1999,  the Company  entered into an interest rate swap agreement in
which $90 million of its Gas Facility Revenue Bonds,  6.75% Series A and B, were
effectively exchanged for floating rate debt. (See Note 10, "Hedging, Derivative
Financial Instruments and Fair Values.")

In December 1998, the Company  purchased a portfolio of securities  representing
direct purchase  obligations of the United States  Government.  These securities
were placed in trust,  irrevocably  dedicated  to the  repayment  of certain Gas
Facilities  Revenue Bonds,  thereby effecting an in- substance  defeasance.  The
in-substance defeasance,  of approximately $8.6 million,  represented $4 million
of outstanding  bonds of each of the 6.75% Series 1989A due February 1, 2024 and
6.75% Series 1989B due February 1, 2024 including interest.  The Company has not
been relieved of its

                                       21

<PAGE>



obligation  and  remains  the  primary  obligor  for this debt.  Therefore,  the
liability is recognized on the accompanying Consolidated Balance Sheet.

AUTHORITY FINANCING NOTES: The Company's electric generation subsidiary can also
issue  tax-  exempt  bonds  through  the New  York  State  Energy  Research  and
Development Authority.  At December 31, 1999, $66 million of Authority Financing
Notes were outstanding.

In October 1999, the Company issued $41.1 million of Authority  Financing  Notes
1999 Series A Pollution  Control  Revenue Bonds due October 1, 2028. The initial
interest  rate on these  bonds  was  established  at 3.95% and  applied  through
January  13,  2000.  Thereafter,  the  interest  rate will be reset  based on an
auction  procedure.  The proceeds  from this  issuance were used to extinguish a
portion  of the  Company's  obligation  under a  promissory  note to LIPA.  (See
"Promissory Notes" for additional information.)

The Company  also has  outstanding  $24.9  million  variable  rate 1997 Series A
Electric  Facilities  Revenue  Bonds due December 1, 2027.  The interest rate on
these bonds is reset weekly and ranged from 2.00% to 5.85% through  December 31,
1999 at which time the average rate was 5.85%.

PROMISSORY   NOTES:  In  accordance  with  the  LIPA  Agreement,   LIPA  assumed
substantially  all of the  outstanding  long-term  debt of LILCO at May 28, 1998
except for the 1997 Series A Electric  Facilities  Revenue Bonds due December 1,
2027 which were assigned to the Company.  In accordance with the LIPA Agreement,
the  Company  issued  promissory  notes  to LIPA  which  represented  an  amount
equivalent  to the sum of: (i) the principal  amount of 7.30% Series  Debentures
due July 15, 1999 and 8.20% Series  Debentures due March 15, 2023 outstanding at
May 28,  1998,  and (ii) an  allocation  of certain of the  Authority  Financing
Notes. The promissory  notes contain  identical terms as the debt referred to in
items (i) and (ii) above.

In October 1999, the Company extinguished its obligation under a promissory note
to LIPA, as previously  indicated,  relating to the 7.50% 1976A Series Pollution
Control Revenue Bonds due December 1, 2006 and the 7.80% 1979B Series  Pollution
Control  Revenue Bonds due December 1, 2009. The Company's  obligation for these
bonds of $47.2 million  consisted of the  principal  amount of $45.5 million and
$1.7  million of  interest  accrued and unpaid.  In  addition,  in June 1999 the
Company  extinguished its obligation under a promissory note to LIPA relating to
the 7.30%  Debentures  due July 15, 1999.  The  Company's  obligation  for these
debentures of $411.5 million  consisted of the principal  amount of $397 million
and $14.5  million of interest  accrued and unpaid.  The  carrying  value of the
promissory notes at December 31, 1999 was $602.4 million.

The  promissory  notes issued to LIPA included an allocation  for certain of the
Authority  Financing Notes. On March 1, 1999, LIPA converted the weekly variable
interest  rate  features  on the  Authority  Financing  Notes  Series  1993B due
November 1, 2023,  Series  1994A due October 1, 2024 and Series 1995A due August
1, 2025 to a fixed rate of 5.30%. In addition,  on March 1, 1999, LIPA converted
the annual  variable  interest rate features on the  Authority  Financing  Notes
Series 1985A

                                       22

<PAGE>



due March 1, 2016 and Series 1985B due March 1, 2016 to a fixed rate of 5.15%.


OTHER LONG-TERM DEBT: On February 1, 2000,  Brooklyn Union of Long Island issued
$400 million of 7.875 % Medium Term Notes due February 1, 2010. The net proceeds
from the issuance of these notes were used to repay the Company for its costs in
extinguishing  certain  promissory  notes  to LIPA,  as  previously  noted.  For
additional  information on Brooklyn Union of Long Island's issuance see Note 12,
"KeySpan Gas East Corporation Summary Financial Data".

THEC has an  unsecured  available  line of credit  with a  commercial  bank that
provides for a maximum commitment of $250 million subject to certain conditions,
which supports borrowings under a revolving loan agreement.  Up to $2 million of
this line is  available  for the  issuance  of  letters  of  credit  to  support
performance  guarantees.  This credit  facility  matures on March 1, 2003.  THEC
borrowed $48 million under this facility  during 1999, and at December 31, 1999,
borrowings of $181 million were outstanding and $0.4 million was committed under
outstanding  letter of credit  obligations.  Borrowings under this facility bear
interest,  at THEC's option,  at rates indexed at a premium to the Federal Funds
rate or LIBOR rate, or based on the prime rate.  The weighted  average  interest
rate on this debt was 6.59% at December 31, 1999.  In addition,  at December 31,
1999,  THEC had $100  million  of  8.625%  Senior  Subordinated  Notes  due 2008
outstanding.  These notes were issued in a private  placement  in March 1998 and
are subordinate to borrowings under THEC's line of credit.

A subsidiary of the Energy Related  Investment  segment has a revolving 12 month
loan  agreement with a financial  institution  in Canada at the Canadian  Dollar
Deposit Offered Rate. During 1999,  borrowings under this agreement were US$13.5
million.  At December 31, 1999 borrowings of US$86.4 million were outstanding at
an  interest  rate  of  5.60%.  These  borrowings  were  used  to  fund  capital
expenditures.

DEBT MATURITY SCHEDULE: The Company does not have any long-term debt maturing in
the next five years.

NOTE 8.  NOTES PAYABLE

In November  1999,  the  Company  negotiated  a $700  million  revolving  credit
agreement,  with a one- year term and one-year renewal option, with a commercial
bank.  Pricing  under the  facility is subject to a  ratings-based  grid with an
annual fee of .075% per annum on the balance of funds available. Borrowings will
bear interest at LIBOR plus 50 basis  points.  Borrowings in excess of more than
33% of the total  commitment will bear interest at LIBOR plus 62.5 basis points.
This credit  facility is used to support the Company's  $700 million  commercial
paper  program.  The Company  began issuing  commercial  paper during the fourth
quarter of 1999.  The average daily  outstanding  balance during the quarter was
$199.2  million at a weighted  average  annualized  interest  rate of 6.54%.  At
December  31,  1999,  the  Company  had  $208.3  million  of  commercial   paper
outstanding at an

                                       23

<PAGE>



annualized  interest rate of 6.56%.  The proceeds  received from the issuance of
commercial  paper was used to repay  outstanding  borrowings under the Company's
previous  existing line of credit  (discussed  below) and for general  corporate
purposes.  During 2000, the Company  anticipates issuing commercial paper rather
than borrowing on the revolving credit agreement.

Prior to the new revolving credit  agreement and commercial  paper program,  the
Company  had an  available  unsecured  bank  line of  credit  of  $300  million.
Borrowings were made under this facility during the months of September, October
and November 1999. The average daily outstanding balance during these months was
$83.7 million at a weighted average annualized interest rate of 5.53%. This line
of  credit  was  terminated  upon  the  execution  of the new  revolving  credit
agreement.

NOTE 9. CONTRACTUAL OBLIGATIONS AND CONTINGENCIES

LEASE OBLIGATIONS:  Lease costs included in operation expense were $47.1 million
in 1999  reflecting,  primarily,  the Ravenswood  lease of $11.6 million and the
lease of the Company's Brooklyn headquarters of $11.3 million.  Lease costs also
include  leases  for  other  buildings,  office  equipment,  vehicles  and power
operated equipment. Lease costs for the nine months ended December 31, 1998 were
$28.9 million.  The future minimum lease payments under various  leases,  all of
which are operating leases,  are $51.8 million per year over the next five years
and $108.2 million, in the aggregate, for all years thereafter.

The Company  acquired the 2,168  megawatt  Ravenswood  Facility  located in Long
Island  City,   Queens,  New  York,  from  Con  Edison  on  June  18,  1999  for
approximately  $597  million.  In order to  reduce  its cash  requirements,  the
Company  entered into a lease  agreement  with a special  purpose,  unaffiliated
financing  entity  that  acquired a portion of the  facility  directly  from Con
Edison and leased it to a subsidiary of the Company under a ten year lease.  The
Company has guaranteed all payment and performance obligations of its subsidiary
under the lease.  Another  subsidiary  of the Company  provides  all  operating,
maintenance  and  construction  services for the facility.  The lease relates to
approximately  $425 million of the acquisition  cost of the facility.  The lease
qualifies  as  an  operating  lease  for  financial   reporting  purposes  while
preserving the Company's  ownership of the facility for federal and state income
tax  purposes.  The  balance of the funds  needed to acquire the  facility  were
provided from cash on hand.

In connection with the financing of the  acquisition of the Ravenswood  Facility
in June 1999 by a wholly-owned  subsidiary of the Company,  certain post-closing
conditions including the transfer of certain governmental permits,  receipt of a
consent  order for the facility  and the delivery of evidence  that the facility
complies with applicable  zoning  requirements  were to be fulfilled by December
15,  1999.  Following  notice to  affected  parties,  including  the  holders of
approximately  $412 million of notes issued in connection with the  acquisition,
the Company was advised in January 2000 that several such  noteholders  believed
the steps taken thus far were not  sufficient to satisfy fully the  post-closing
conditions.  Under the  relevant  financing  documents,  failure to complete the
required  actions on a timely basis  constitutes  an Event of Default,  which in
turn could

                                       24

give various parties to the Ravenswood financing, including the noteholders, the
right to foreclose on the  Ravenswood  property  and/or  terminate the Company's
leasehold  interest and rights in the property.  To date, no party has sought to
take or indicated that it is contemplating  taking any such action.  The Company
has timely  fulfilled  all of its payment  obligations  and believes that it has
also  timely  fulfilled  all  other  obligations  under the  relevant  financing
documents.

The  Company  is  currently  seeking  to  resolve  remaining  issues  concerning
compliance  with the  December 15  post-closing  conditions  and, in  connection
therewith,  has  obtained  extensions  of  the  deadlines  for  certain  of  the
conditions.

FIXED CHARGES UNDER FIRM  CONTRACTS:  The Company's  utility  subsidiaries  have
entered into various  contracts for gas delivery,  storage and supply  services.
The  contracts  have  remaining  terms that cover  from one to  fourteen  years.
Certain  of these  contracts  require  payment of annual  demand  charges in the
aggregate amount of approximately $280 million.  The Company is liable for these
payments regardless of the level of service it requires from third parties. Such
charges  are,  currently,  recovered  from utility  customers  as gas costs.  In
response to a NYPSC policy statement regarding gas industry  restructuring,  the
Company estimated that, if the gas distribution subsidiaries were to continue to
recover  the  demand  charges  for the  next  five  years,  then  the  estimated
strandable costs (contract costs above market value) for contracts that will not
expire by 2005 and would not be needed to provide service to firm transportation
customers  will be, on a present  value basis,  approximately  $78 million.  For
purposes of this  calculation,  the Company has assumed  that,  if it exited the
merchant  function  and if it were  necessary  to assign the  contracts to third
parties,  the Company could recover the market value of the  underlying  assets.
Therefore, the difference between the contract costs and the market value is the
potential "strandable" costs.

LEGAL  MATTERS:  From time to time,  the  Company is  subject  to various  legal
proceedings  arising  out of the  ordinary  course  of its  business.  Except as
described  below,  the Company does not consider any of such  proceedings  to be
material to its business or likely to result in a material adverse effect on its
results of operations or financial condition.

In October 1998,  the County of Suffolk and the Towns of Huntington  and Babylon
commenced  an action  against  LIPA,  the  Company,  the NYPSC and others in the
United  States  District  Court  for  the  Eastern  District  of New  York  (the
"Huntington Lawsuit").  The Huntington Lawsuit alleges, among other things, that
LILCO  ratepayers  (i) have a property  right to receive or share in the alleged
capital gain that resulted from the transaction with LIPA (which gain is alleged
to be at least $1  billion);  and (ii)  that  LILCO  was  required  to refund to
ratepayers the amount of a Shoreham-related  deferred tax reserve (alleged to be
at least $800 million)  carried on the books of LILCO at the consummation of the
LIPA  Transaction.  In December  1998,  and again in June 1999,  the  plaintiffs
amended their complaint.  The amended complaint contains allegations relating to
certain  payments LILCO had determined  were payable in connection with the LIPA
Transaction  and  KeySpan  Acquisition  to LILCO's  chairman  and certain of its
officers and adds the  recipients of the payments as  defendants.  In June 1999,
the Company was served with the second amended complaint. On August 23, 1999,

                                       25

<PAGE>



the Company filed a motion to dismiss the second amended complaint.  Pursuant to
an  agreement  among the  parties,  the  Company's  motion to  dismiss  is being
converted to a summary  judgment  motion.  At this time the Company is unable to
determine the outcome of this ongoing proceeding.



THE CLASS SETTLEMENT: The Class Settlement,  which became effective in June 1989
(County of Suffolk,  et al., v. Long Island Lighting Company et al.), resolved a
civil lawsuit against LILCO brought under the federal  Racketeer  Influenced and
Corrupt  Organizations  Act,  alleging  that LILCO made  inadequate  disclosures
before  the  NYPSC   concerning  the  construction  and  completion  of  nuclear
generating  facilities.  The class settlement  provided electric  customers with
rate  reductions of $390.0  million that were being  reflected as adjustments to
their monthly electric bills over a ten-year period which began on June 1, 1990.
The Class  Settlement  obligation of  approximately  $20 million at December 31,
1999 reflects the present  value of the  remaining  reductions to be refunded to
customers. As a result of the LIPA Transaction,  LIPA will provide the remaining
balance to its electric  customers as an adjustment  to their  monthly  electric
bills.  The Company will then,  in turn,  reimburse  LIPA on a monthly basis for
such reductions on the customer's  monthly bill. The Company remains  ultimately
obligated under the Class  Settlement.  In November 1999,  class counsel for the
LILCO  ratepayers  served a motion,  in the United States District Court for the
Eastern District of New York,  seeking an order directing the Company to pay $42
million,  in  addition  to the  amounts  remaining  to be paid  under  the Class
Settlement. Class counsel contends that the required rate reductions should have
been  exclusive of gross  receipts  taxes.  The Company filed its  opposition in
January 2000 and class  counsel  filed their reply papers in February  2000.  In
their  February  papers,  class  counsel  revised  their demand to seek an order
directing  the Company to pay  approximately  $22  million,  plus  interest,  in
addition to the amounts  remaining  to be paid under the Class  Settlement.  The
Company filed its rebuttal papers March 1, 2000 and oral argument was held March
6, 2000.  On March 9,  2000,  an order was  issued by the court  granting  class
counsel's  motion.  The Company is in the process of  evaluating  the order and,
accordingly,  is  currently  unable to  determine  the  ultimate  outcome of the
proceeding  or what effect,  if any,  such  outcome  will have on its  financial
condition or results of operations.

ENVIRONMENTAL MATTERS - MANUFACTURED GAS PLANT SITES: The Company has identified
twenty-six manufactured gas plant ("MGP") sites which were historically owned or
operated by Brooklyn Union or Brooklyn Union of Long Island (or such  companies'
predecessors).  Operations  at these  plants in the late 1800's and early 1900's
may have  resulted in the release of hazardous  substances.  These former sites,
some of which are no longer owned by the Company,  have been  identified to both
the  New  York  State  Department  of  Environmental  Conservation  ("DEC")  for
inclusion on appropriate waste site inventories and the PSC. The currently-known
conditions of fourteen of these former MGP sites,  their period and magnitude of
operation,  generally  observed cleanup  requirements and costs in the industry,
current land use and  ownership,  and  possible  reuse have been  considered  in
establishing contingency reserves that are discussed below.

In 1995,  Brooklyn Union executed an  Administrative  Orders on Consent  ("ACO")
with the DEC

                                       26

<PAGE>



which  addressed the  investigation  and  remediation of a site in Coney Island,
Brooklyn.  In 1998,  Brooklyn  Union executed an ACO for the  investigation  and
remediation of the Clifton MGP site in Staten  Island.  At the initiative of the
DEC, the City of New York and the Company are in  negotiations on a cost sharing
arrangement  to  conduct  investigations  in 2000 at the  Citizen's  MGP site in
Brooklyn,  which is now primarily  owned by the City, but was formerly owned and
operated by a Brooklyn Union  predecessor.  The DEC notified the Company in 1998
that the Sag Harbor and Rockaway Park MGP sites owned by Brooklyn  Union of Long
Island  would  require   remediation  under  the  State's   Superfund   program.
Accordingly,  the Sag Harbor and Rockaway Park sites;  as well as the Bay Shore,
Glen Cove,  Halesite and  Hempstead  MGP sites;  are the subject of two separate
ACOs,  which the  Company  executed  with the DEC in March and  September  1999,
respectively.   Field  investigations  and,  in  some  cases,  interim  remedial
measures,  are  underway or  scheduled to occur at each of these sites under the
supervision of the DEC and the New York State Department of Health.

The  Company  was  also  requested  by  the  DEC  to  perform  preliminary  site
assessments at the Patchogue,  Babylon, Far Rockaway,  Garden City and Hempstead
(Clinton  St.) MGP sites,  each of which were formerly  owned by LILCO,  under a
separate ACO entered into in September 1999.  Initial studies based on existing,
available  documentation  have been completed for each such site and the DEC has
requested  that the Company  collect  additional  samples at each of the subject
properties.

With the  exception  of the Coney  Island site,  which will be  redeveloped  for
commercial or industrial use, the final end uses for the sites  identified above
and, therefore,  acceptable remediation goals have not yet been determined.  The
Company is required to prepare a feasibility  study for the  remediation of each
such site,  based on cleanup levels derived from risk analyses  associated  with
the  proposed or  anticipated  future use of the  properties.  The  schedule for
completing  this  phase of the work  under  the  ACOs for the  identified  sites
discussed above extends through 2001.

Thus, thirteen sites identified above are currently the subject of ACOs with the
DEC and one is subject to the  negotiation  of such an agreement.  The Company's
remaining  MGP  sites  may  not  become  subject  to  ACOs  in the  future,  and
accordingly no liability has been accrued for these sites. It is possible, based
on  future  investigation,  that  the  Company  may  be  required  to  undertake
investigation  and potential  remediation  efforts at these,  or other currently
unknown former MGP sites.  However, the Company is currently unable to determine
whether or to what extent such additional costs may be incurred.

The  Company  believes  that  in  the  aggregate,   the  accrued  liability  for
investigation  and remediation of the MGP sites  identified above are reasonable
estimates  of  likely  cost  within a range of  reasonable,  foreseeable  costs.
Accordingly,  the  Company  presently  estimates  the cost of its  MGP-  related
environmental  cleanup  activities  will be $123 million;  which amount has been
accrued  by  the  Company  as  its  current  best   estimate  of  its  aggregate
environmental  liability  for known sites.  As previously  indicated,  the total
MGP-related  costs  may be  substantially  higher,  depending  upon  remediation
experience,  selected end use for each site, and actual environmental conditions
encountered.

                                       27

<PAGE>



The NYPSC  approved  rate plans for Brooklyn  Union and  Brooklyn  Union of Long
Island provide for the recovery of such investigation and remediation costs. The
Brooklyn Union rate plan provides, among other things, that if the total cost of
investigation and remediation  varies from that which is specifically  estimated
for a site under  investigation  and/or  remediation,  then Brooklyn  Union will
retain or absorb up to 10% of the  variation.  The Brooklyn Union of Long Island
rate plan also provides for the recovery of investigation  and remediation costs
but with no consideration of the difference  between estimated and actual costs.
Under  prior  rate  orders,  Brooklyn  Union has  offset  certain  moneys due to
ratepayers against its estimated  environmental  cleanup costs for MGP sites. At
December  31,  1999,  the Company  has  reflected  a  regulatory  asset of $95.6
million.   Expenditures  incurred  to  date  by  the  Company  with  respect  to
MGP-related activities total $15.9 million.

Periodic  discussions by the Company with  insurance  carriers and third parties
for  reimbursement  of some portion of MGP site  investigation  and  remediation
costs continue.  In December 1996,  LILCO filed a complaint in the United States
District Court for the Southern District of New York against fourteen  insurance
companies  that issued general  comprehensive  liability  policies to LILCO.  In
January 1998, LILCO commenced a similar action against the same, and additional,
insurance  companies  in New York State  Supreme  Court,  and the federal  court
action subsequently was dismissed.  The state court action is being conducted by
the  Company on behalf of  Brooklyn  Union of Long  Island.  The outcome of this
proceeding  cannot  yet  be  determined.  In  addition,  Brooklyn  Union  is  in
discussions  with  insurance  carriers  regarding  the  possible  resolution  of
coverage claims related to its MGP site investigation and remediation activities
without  litigation.  The  Company is not able to predict  the  outcome of these
discussions.

ENVIRONMENTAL MATTERS - OTHER: The Company will be responsible for environmental
obligations   relating  to  the  Ravenswood   Facility   operations  other  than
liabilities arising from pre-closing disposal of waste at off-site locations and
any  monetary  fines  arising from Con Edison's  pre-closing  conduct.  Based on
information  currently available for environmental  contingencies related to the
Ravenswood  Facility  acquisition,  the  Company has  accrued an  additional  $5
million as the minimum liability to be incurred.

The  Company is  awaiting  final  development  of state and  federal  regulatory
programs  with respect to NOx  reduction  requirements  for its  existing  power
plants.  The  Company's  compliance  strategy  may be  composed  of fuel  choice
decisions, acquisition of emission credits, and installation of emission control
equipment.  The extent of  development of new generation in the region will also
impact the Company's compliance strategy. Although the Company is evaluating its
alternatives,   final  decisions   cannot  be  made  until  pending   regulatory
requirements  and  new  generation  decisions  are  clarified.  Expenditures  to
implement a final strategy are not expected to begin until 2001.

Additional capital expenditures associated with the renewal of the surface water
discharge  permits for the  Company's  power  plants may be required by the DEC.
Until the  Company's  monitoring  obligations  are  completed and changes to the
Environmental Protection Agency regulations under Section 316 of the Clean Water
Act are promulgated, the need for and the cost of equipment

                                       28

upgrades cannot be determined.

NOTE 10.  HEDGING, DERIVATIVE FINANCIAL INSTRUMENTS, AND FAIR VALUES

NATURAL GAS AND OIL FUTURES, OPTIONS AND SWAPS: The Company's utility, marketing
and gas  exploration and production  subsidiaries  employ  derivative  financial
instruments,  such as natural gas and oil  futures,  options and swaps,  for the
purpose of hedging exposure to commodity price risk.

Utility tariffs  applicable to certain  large-volume  customers permit gas to be
sold at prices  established  monthly  within a specified  range  expressed  as a
percentage of prevailing  alternate  fuel oil prices.  The Company uses gas swap
contracts,  with offsetting positions in oil swap contracts of equivalent energy
value,  with third  parties to fix profit  margins on specified  portions of the
sales to its large- volume market.  The "long" gas position  follows,  generally
within a range of 80% to 120%,  the cost of gas to serve this  market  while the
offsetting oil swap position correspondingly replicates,  within the same range,
the selling  price of gas.  The Company also uses  standard New York  Mercantile
Exchange  ("NYMEX") gas futures to stabilize gas price  volatility  for its firm
customers during the winter months as recommended by the NYPSC.

KeySpan  Energy  Services  ("KES"),  the  Company's  gas and electric  marketing
subsidiary,  sells gas at fixed annual rates and utilizes standard NYMEX futures
contracts and swaps to fix profit margins.  In the swap  instruments,  which are
employed to hedge  exposure to basis risk, KES pays the other parties the amount
by which the floating variable price (settlement price) is below the fixed price
and receives the amount by which the settlement price exceeds the fixed price.

THEC  utilizes  collars to hedge future sales prices on a portion of its natural
gas production to achieve a more predictable cash flow, as well as to reduce its
exposure to adverse price fluctuations of natural gas. For any particular collar
transaction,  the  counter  party is  required  to make a payment to THEC if the
settlement  price for any  settlement  period is below the floor  price for such
transaction,  and THEC is required to make  payment to the counter  party if the
settlement  price for any settlement  period is above the ceiling price for such
transaction. For any particular floor transaction, the counter party is required
to make a payment to THEC if the settlement  price for any settlement  period is
below the floor  price for such  transaction.  THEC is not  required to make any
payment in connection with a floor transaction.

The following  table sets forth  selected  financial  data  associated  with the
Company's derivative financial instruments that were outstanding at December 31,
1999.

The fair values shown in the above table represent the amounts the Company would
have  received or paid if it had closed those  derivative  positions on December
31,  1999.  If the Company had applied the  requirements  of SFAS No. 133 to the
above  derivative  financial  instruments  at December 31,  1999,  comprehensive
income would have reflected a reduction of $6.0 million.

As of December 31, 1999, no futures  contract  extended  beyond  November  2000.
Margin  deposits with brokers at December 31, 1999 of $4.0 million were recorded
in other in the  current  assets  section  of the  Consolidated  Balance  Sheet.
Deferred losses on closed positions were $5.4 million at December 31, 1999. Such
deferrals are generally recorded in net income within one month.

The  Company  and its  subsidiaries  are  exposed to credit risk in the event of
nonperformance   by  counterparties   to  derivative   contracts,   as  well  as
nonperformance by the counterparties of the transactions  against which they are
hedged.  The  Company  believes  that the credit  risk  related to the  futures,
options and swap contracts is no greater than that  associated  with the primary
contracts which they hedge, as these contracts are with major  investment  grade
financial  institutions,  and that  elimination of the price risk lowers overall
business risk.

INTEREST RATE SWAPS: In November 1999, the Company entered into an interest rate
swap agreement in which $90 million of its Gas Facilities  Revenue Bonds,  6.75%
Series A and B, were  effectively  exchanged  for floating rate debt at The Bond
Market  Association  Swap Index.  The interest  rate swap  agreement  expires in
twenty-five  years,  but can be terminated  earlier based on certain  market and
contract conditions.  For the term of the agreement,  the Company will receive a
fixed interest payment of 5.54%. The variable interest rate is reset on a weekly
basis.  For the period November 10, 1999 through  December 31, 1999 the weighted
average variable  interest rate that the Company was obligated to pay was 3.89%.
The gain on the  interest  rate swap,  which was  immaterial,  reduced  recorded
interest expense.  The fair value of the interest rate swap at December 31, 1999
was $4.2 million and represents the estimated amount that the Company would have
to pay if the swap had been settled at the then current market rate.

In connection  with the Company's  anticipated  purchase of Eastern  Enterprises
(See  Note  11,  "Acquisition  of  Eastern")  and the  anticipated  issuance  of
long-term debt securities for the acquisition,  the Company entered into forward
interest rate lock agreements in January and February 2000 to hedge a portion of
the  risk  that  the  cost of the  future  issuance  of  fixed-rate  debt may be
adversely  affected by changes in interest  rates.  Under an interest  rate lock
agreement,  the  Company  agrees  to pay  or  receive  an  amount  equal  to the
difference  between  the net  present  value of the cash  flows  for a  notional
principal  amount  of  indebtedness  based on the  existing  yield of a  hedging
instrument  at the  date of the  agreement  and at the  date  the  agreement  is
settled.  Gains and losses on interest rate lock agreements will be deferred and
amortized  over the  life of the  underlying  debt to be  issued.  The  notional
amounts of the  agreements  are not  exchanged.  The Company  has  entered  into
interest rate lock agreements with more than one major financial  institution in
order to minimize  counterparty  credit risk.  The details of the four  interest
rate lock agreements are set forth in the following table.

FAIR VALUE OF FINANCIAL  INSTRUMENTS:  The fair value of the Company's preferred
stock at December 31, 1999 was $454.6  million and the carrying value was $447.3
million.  At December 31, 1999 the Company has classified as a current liability
on the  Consolidated  Balance Sheet $363 million of preferred  stock which has a
mandatory redemption requirement of June 1, 2000.

The  Company's   long-term  debt  consists  primarily  of  publicly  traded  Gas
Facilities  Revenue Bonds,  Authority  Financing Notes and Debentures,  the fair
value of which is  estimated  on quoted  market  prices  for the same or similar
issues.  The  Authority  Financing  Notes and  Debentures  are  included  in the
promissory  notes  to  LIPA.  As  previously  indicated,  there  is no  maturing
long-term debt within the next five years.

The fair values and carrying amounts of the Company's long-term debt at December
31, 1999 and December 31, 1998 were as follows:

At December 31, 1999, THEC's $100 million 8.625% Senior  Subordinated  Notes due
2008 had a fair  market  value of $96  million.  All  other  THEC debt and other
subsidiary  debt is  carried  at an  amount  approximating  fair  value  because
interest  rates  are  based  on  current  market  rates.   All  other  financial
instruments  included in the  Consolidated  Balance  Sheet are stated at amounts
that approximate fair values.

NOTE 11.  ACQUISITION OF EASTERN ENTERPRISES

On November 4, 1999, the Company and Eastern Enterprises  ("Eastern")  announced
that the companies  have signed a definitive  merger  agreement  under which the
Company  will acquire all of the common stock of Eastern for $64.00 per share in
cash.  This represents a premium of 24% over the Eastern closing price of $51.56
on  November  3, 1999,  and a 45%  premium  over the  average of the last 90-day
trading period.  The Agreement and Plan of Merger was filed as an exhibit to the
Company's Form 8-K filed on November 5, 1999.

The transaction has a total value of approximately $2.5 billion ($1.7 billion in
equity  and $0.8  billion  in  assumed  debt and  preferred  stock)  and will be
accounted  for as a  purchase.  The  increased  size and  scope of the  combined
organization  should  enable the  Company to  provide  enhanced,  cost-effective
customer service and to capitalize on the above-average growth opportunities for
natural gas in the Northeast and provide  additional  resources to the Company's
unregulated businesses. The combined companies will serve 2.4 million customers.

It is  anticipated  that the combined  company will have assets of $8.8 billion,
$4.3 billion in revenues,  and EBITDA of approximately $950 million. The Company
expects  pre-tax annual cost savings will be  approximately  $30 million.  These
cost savings result  primarily from the  elimination of duplicate  corporate and
administrative  programs,   greater  efficiencies  in  operations  and  business
processes, and

                                       32

<PAGE>



increased purchasing efficiencies. The Company expects to achieve reductions due
to the merger through a variety of programs which would include hiring  freezes,
attrition and separation  programs.  All union  contracts  will be honored.  The
Company  expects to raise $1.7 billion of initial  financing for the transaction
in short-term  markets, a significant  portion of which the Company  anticipates
will be replaced with long-term financing as soon as practicable.

The merger is  conditioned,  among other  things,  upon the  approval of Eastern
shareholders,  the  Securities  and Exchange  Commission  and the New  Hampshire
Public Utility Commission.  The Company anticipates that the transaction will be
consummated  in the third or fourth  quarter of 2000, but is unable to determine
when or if all required approvals will be obtained.

In connection  with the merger,  Eastern has amended its merger  agreement  with
EnergyNorth,  Inc.  ("EnergyNorth")  to provide for an all cash  acquisition  of
EnergyNorth shares at a price per share of $61.13. The restructured  EnergyNorth
merger  is  expected  to  close   contemporaneously   with  the  KeySpan/Eastern
transaction.

Following  the  announcement  that the Company has entered  into an agreement to
purchase  Eastern  Enterprises,  Standard & Poor's  Rating  Services  placed the
Company's  and  certain of its  subsidiaries',  as well as  Eastern's  corporate
credit, senior unsecured debt, and preferred stock on Credit Watch with negative
implications. Similarly, Moody's Investors Service also placed the Company's and
certain of its  subsidiaries',  as well as Eastern's  corporate  credit,  senior
unsecured  debt,  commercial  paper and  preferred  stock on review for possible
downgrade.

Eastern owns and operates  Boston Gas Company,  Colonial Gas Company,  Essex Gas
Company, Midland Enterprises Inc. ("Midland"),  Transgas Inc. ("Transgas"),  and
ServicEdge Partners, Inc. ("ServicEdge").  Upon completion of the pending merger
with EnergyNorth, Inc., Eastern will serve over 800,000 natural gas customers in
Massachusetts and New Hampshire. Midland,  headquartered in Cincinnati, Ohio, is
the leading carrier of coal and a major carrier of other dry bulk cargoes on the
nation's  inland  waterways.  Transgas  is the  nation's  largest  over-the-road
transporter  of liquefied  natural gas.  ServicEdge  is the largest  unregulated
provider of residential HVAC equipment  installation and service to customers in
Massachusetts.

NOTE 12. KEYSPAN GAS EAST CORPORATION SUMMARY FINANCIAL DATA

KeySpan Gas East  Corporation  d/b/a Brooklyn Union of Long Island,  is a wholly
owned  subsidiary  of KeySpan  Corporation.  Brooklyn  Union of Long  Island was
formed  on May 7, 1998 and on May 28,  1998  acquired  substantially  all of the
assets related to the gas distribution  business of LILCO  immediately  prior to
the LIPA  Transaction.  Brooklyn Union of Long Island provides gas  distribution
services to customers in the Long Island  counties of Nassau and Suffolk and the
Rockaway peninsula of Queens county. Brooklyn Union of Long Island established a
program for the  issuance,  from time to time,  of up to $600 million  aggregate
principal amount of Medium-Term Notes,  which will be fully and  unconditionally
guaranteed by the Company. On February 1, 2000,

                                       33

Brooklyn  Union of Long Island  issued $400 million of 7.875%  Medium Term Notes
due 2010. The following  represents  summarized  balance sheet data for Brooklyn
Union of Long Island.

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

      (1)Net  Assets   reflect   total  assets  less   current  and   noncurrent
         liabilities.  Intercompany  accounts receivable are included in current
         assets and  long-term  intercompany  accounts  payable are  included in
         noncurrent liabilities.

Prior to the LIPA Transaction, certain of LILCO's income statement accounts were
recorded  in its books and records as  directly  related to its gas  operations.
These items  included:  revenues,  purchased gas costs,  certain  operations and
maintenance ("O&M") expenses,  depreciation of gas utility plant, revenue taxes,
certain other income and deductions, and federal income taxes.

Certain  income and expense  accounts  common to both  LILCO's gas and  electric
operations prior to the LIPA Transaction have been allocated/determined based on
the following  basis,  which is consistent with the methodology  utilized by the
NYPSC to establish rates.

Common O&M expenses, operating taxes (excluding revenue taxes) and miscellaneous
income and deductions were based upon methodologies employing:  number of active
meters; revenues;  utility plant; and labor associated with gas operations, as a
percentage of total operations.

Interest income, interest expense and preferred stock dividend requirements were
allocated  based upon gas utility plant as a percentage of total utility  plant,
(including certain electric related regulatory assets), adjusted for appropriate
deferred federal income taxes.

Depreciation  on common plant was based upon an annual study of the  utilization
of common facilities by the gas and electric operations of LILCO.

The Company believes that the basis of allocation described above is reasonable.
Reported  results of  operations  and the  financial  position  of  LILCO's  gas
operations  may have been  different  if such  operations  were  conducted  as a
separate  subsidiary of LILCO,  rather than as part of a combined integrated gas
and electric company.

Certain common assets which were previously part of LILCO's  operations prior to
May 28, 1998

                                            34

have been transferred to other  subsidiaries of the Company (e.g.  common plant,
inventory,  etc.).  Income and expenses related to these assets prior to May 28,
1998 have been allocated in the accompanying financial statements. After May 28,
1998, Brooklyn Union of Long Island has been charged by affiliated companies for
the use of these assets,  resulting in an operating expense of $10.8 million for
the twelve  months ended  December 31, 1999 and $7.2 million for the nine months
ended December 31, 1998.

The following represents  summarized income statement data for Brooklyn Union of
Long Island.

(1)For the period  April 1, 1998  through May 28, 1998 (the period  prior to the
   LIPA Transaction),  certain income and expense items,  common to both LILCO's
   gas  and  electric  operations,  were  allocated  to  its  gas  and  electric
   operations consistent with the methodology utilized by the NYPSC to establish
   rates.
(2)Operating  income is  defined  as  revenues  less  cost of gas and  operating
   expenses.  Operating expenses include the following expenses:  operations and
   maintenance,  depreciation and amortization and operating taxes. Further, for
   the  nine  months  ended  December  31,  1998  operating  income  includes  a
   before-tax charge of $8.7 million reflecting  Brooklyn Union of Long Island's
   portion of an early retirement program implemented by the Company.

NOTE 13.   SHAREHOLDER RIGHTS PLAN

On March 30, 1999 the Board of  Directors of the Company  adopted a  Shareholder
Rights  Plan (the  "Plan")  designed to protect  shareholders  in the event of a
proposed takeover of the Company. The Plan creates a mechanism that would dilute
the  ownership  interest  of  a  potential   unauthorized   acquirer.  The  Plan
establishes one preferred stock purchase "right" for each  outstanding  share of
common  stock to  shareholders  of record on April 14,  1999.  Each right,  when
exercisable,  entitles  the  holder to  purchase  1/100th of a share of Series D
Preferred Stock, at a price of $95.00.  The rights generally become  exercisable
following the acquisition of more than 20 percent of the Company's  common stock
without  the  consent of the  Company's  Board of  Directors.  Prior to becoming
exercisable,  the rights are  redeemable by the Board of Directors for $0.01 per
right. If not so redeemed, the rights will expire on March 30, 2009.

NOTE 14. SALE OF LILCO ASSETS,  ACQUISITION  OF KEYSPAN ENERGY  CORPORATION  AND
TRANSFER OF ASSETS AND LIABILITIES TO THE COMPANY

On May 28, 1998, pursuant to the Agreement and Plan of Merger,  dated as of June
26, 1997 as amended, by and among the Company, LILCO, LIPA, and LIPA Acquisition
Corp.  (the "Merger  Agreement"),  LIPA acquired all of the  outstanding  common
stock of LILCO for $2.4975 billion in cash and thereafter directly or indirectly
assumed certain  liabilities  including  approximately  $3.4 billion in debt. In
addition,  LIPA  reimbursed  LILCO $339.1  million  related to certain series of
preferred stock which were redeemed by LILCO prior to May 28, 1998.  Immediately
prior to such acquisition,  all of LILCO's assets employed in 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
T&D business and its gas distribution  business and/or its non-nuclear  electric
generation  business  (the  "Transferred  Assets")  were sold to the Company and
transferred  to  wholly-owned  subsidiaries  of the  Company  at  the  Company's
direction.

The consideration  for the Transferred  Assets consisted of (i) 3,440,625 shares
of the common stock of the Company (ii) 553,000 shares of the Series B preferred
stock of the Company,  (iii) 197,000  shares of the Series C preferred  stock of
the Company,  and (iv) the  assumption by the Company of certain  liabilities of
LILCO.  In connection  with the transfer and prior to the  effectiveness  of the
LIPA Transaction, LILCO sold Series B and C preferred stock for $75 million in a
private placement.

Moreover,  all of LILCO's outstanding  long-term debt as of May 28, 1998, except
for its 1997 Series A Electric  Facilities  Revenue  Bonds due  December 1, 2027
which were assigned to the Company,  was assumed by LIPA. In accordance with the
LIPA  Transaction,  the Company  issued  promissory  notes to LIPA  amounting to
$1.048  billion  which  represented  an amount  equivalent to the sum of (i) the
principal  amount of 7.30% Series  Debentures due July 15, 1999 and 8.20% Series
Debentures  due March  15,  2023  outstanding  as of May 28,  1998,  and (ii) an
allocation of certain of the Authority  Financing  Notes.  The promissory  notes
contain  identical  terms to the debt  referred  to in items (i) and (ii) above.
(See Note 7, "Long-Term Debt" for additional information.)

On May 28, 1998, immediately subsequent to the LIPA Transaction,  KSE was merged
with and into a subsidiary of the Company,  pursuant to an Agreement and Plan of
Exchange and Merger,  dated as of December 29, 1996,  between LILCO and Brooklyn
Union.  This agreement was amended and/or  restated as of February 7, 1997, June
26, 1997, and September 29, 1997, to reflect certain  technical  changes and the
assignment  by  Brooklyn  Union of all of its rights and  obligations  under the
agreement  to KSE.  On  September  29,  1997,  KSE became the parent  company of
Brooklyn Union when Brooklyn Union reorganized into a holding company structure.

As a result of these  transactions,  holders of KSE common  stock  received  one
share of the

                                            36

<PAGE>



Company's  common  stock,  par value $.01 per share,  for each share of KSE they
owned  and  holders  of  LILCO  common  stock  received  0.880 of a share of the
Company's  common stock for each share of LILCO they owned.  Upon the closing of
these  transactions,  former  holders  of KSE  and  LILCO  owned  32%  and  68%,
respectively, of the Company's common stock.

The  purchase  price  of  $1.223  billion  for the  acquisition  of KSE has been
allocated to assets acquired and liabilities  assumed based upon their estimated
fair values. The fair value of the utility assets acquired is represented by its
book value which  approximates the value recognized by the NYPSC in establishing
rates  for  regulated  utility  services.  The  estimated  fair  value  of KSE's
non-utility  assets  approximated  their carrying  values.  At May 28, 1998, the
Company  recorded  goodwill  in  the  amount  of  $170.9  million,  representing
primarily  the  excess of the  acquisition  cost over the fair  value of the net
assets acquired; the goodwill is being amortized over 40 years.

The following is the comparative unaudited proforma combined condensed financial
information  for the nine months ended  December 31, 1998 and the twelve  months
ended March 31,  1998.  The  proforma  disclosures  are  intended to reflect the
results of operations as if the KeySpan Acquisition was consummated on the first
day of each of the reporting  periods below. The effects of the LIPA Transaction
have been reflected for the period May 29, 1998 through December 31, 1998. These
disclosures may not be indicative of future results.

NOTE 15. COSTS RELATED TO THE LIPA TRANSACTION AND SPECIAL CHARGES

Special  charges for the nine months ended December 31, 1998 were $258.5 million
after-tax. These charges reflect, in part, non-recurring charges associated with
the LIPA  Transaction  of $107.9 million  after-tax.  Costs relating to the LIPA
Transaction  principally  reflect taxes  associated with the sale of assets (the
"Transferred  Assets")  to the  Company  by  LIPA;  the  write-  off of  certain
regulatory assets that were no longer recoverable under various LIPA agreements;
and other transaction  costs incurred to consummate the LIPA Transaction.  These
charges were offset,  in part, by tax benefits  relating to the deferred federal
income taxes necessary to account for the difference between the carryover basis
of the Transferred Assets for financial reporting purposes and the new increased
tax  basis  of the  assets,  and  tax  benefits  recognized  on the  funding  of
postretirement benefits for employees of the Company.


                                            37

<PAGE>



Further,  the Company  incurred  charges  related to the KeySpan  Acquisition of
$83.5 million after-tax.  These charges reflect a $42.0 million after-tax charge
for an early  retirement  program  initiated by the Company in December  1998 in
which  approximately 600 employees  participated,  and a $41.5 million after-tax
charge for the write-off of a customer  billing system that was in  development.
Also,  in December  1998,  the Company made a $20 million  donation ($13 million
after-tax) to establish the KeySpan Foundation,  a not-for-profit  philanthropic
foundation that will make donations to local charitable community organizations.

Special  charges also reflect an after-tax  impairment  charge of $54.1 million,
which represents the Company's share of the impairment  charge,  recorded by the
Company's gas and oil exploration and production  subsidiary to reduce the value
of its proved gas reserves in accordance with the asset ceiling test limitations
of the  Securities and Exchange  Commission  applicable to gas  exploration  and
development operations accounted for under the full cost method.

NOTE 16. SUPPLEMENTAL GAS AND OIL DISCLOSURES (UNAUDITED)

This  information  includes  amounts  attributable  to 100% of THEC and  KeySpan
Exploration and Production,  LLC at December 31, 1999.  Shareholders  other than
the Company had a minority interest of 36% in THEC at December 31, 1999 and 1998
and a 34% minority interest in 1997. Gas and oil operations,  and reserves, were

The gas and oil reserves  information  is based on estimates of proved  reserves
attributable to the interest of THEC and KeySpan Exploration and Production, LLC
as of December 31 for each of the years presented.  These estimates  principally
were  prepared  by  independent  petroleum  consultants.   Proved  reserves  are
estimated  quantities  of  natural  gas  and  crude  oil  which  geological  and
engineering  data  demonstrate  with  reasonable  certainty to be recoverable in
future  years  from known  reservoirs  under  existing  economic  and  operating
conditions.

The  standardized  measure of  discounted  future net cash flows was prepared by
applying year-end prices of gas and oil to the proved reserves, except for those
reserves devoted to future  production that is hedged.  Such reserves are priced
at their respective hedged amounts.  The standardized  measure does not purport,
nor should it be interpreted,  to present the fair value of gas and oil reserves
of THEC or KeySpan  Exploration  and  Production  LLC. An estimate of fair value
would also take into account,  among other things,  the recovery of reserves not
presently  classified as proved,  anticipated future changes in prices and costs
and a discount  factor  more  representative  of the time value of money and the
risks inherent in reserve estimates.

REPORT OF ARTHUR ANDERSEN LLP, INDEPENDENT PUBLIC ACCOUNTANTS

To  the Shareholders and Board of Directors of KeySpan Corporation d/b/a KeySpan
    Energy:

We have audited the  accompanying  Consolidated  Balance Sheet and  Consolidated
Statement of Capitalization of KeySpan  Corporation (a New York corporation) and
subsidiaries  as of  December  31,  1999 and  December  31, 1998 and the related
Consolidated Statements of Income, Retained Earnings and Cash Flows for the year
ended  December  31, 1999 and the nine months ended  December  31,  1998.  These
financial  statements are the  responsibility of the Company's  management.  Our
responsibility  is to express an opinion on these financial  statements based on
our audit.

We conducted our audit in accordance with auditing standards  generally accepted
in the United States. 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 audit  provides a  reasonable  basis for our
opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material  respects,  the financial  position and  capitalization  of KeySpan
Corporation  and  subsidiaries as of December 31, 1999 and December 31, 1998 and
the results of their operations and their cash flows for the year ended December
31, 1999 and the nine  months  ended  December  31,  1998,  in  conformity  with
accounting principles generally accepted in the United States.

Our  audit  was  made  for the  purpose  of  forming  an  opinion  on the  basic
consolidated  financial statements taken as a whole. The schedule listed in Item
14 is the  responsibility  of the Company's  management and is presented for the
purpose of complying with the Securities and Exchange  Commission's rules and is
not part of the basic consolidated financial statements.  This schedule has been
subjected  to the  auditing  procedures  applied  in  the  audits  of the  basic
consolidated  financial  statements  and, in our opinion,  fairly  states in all
material  respects  the  financial  data  required  to be set forth  therein  in
relation to the basic consolidated financial statements taken as a whole.

opinion.

In our opinion,  the financial  statements  referred to above present fairly, in

                         THE PROJECT; ISSUANCE OF BONDS

               SECTION  3.1.  The  Project.   Construction  of  the  Project  is
          complete.  The  Project is the  property of the  Company.  In order to
          effectuate the purposes of this Participation  Agreement, the Company,
          in its own name,  will do or cause to be done all things  requisite or
          proper for the  fulfillment  of the  obligations  of the Company under
          this Participation Agreement.

               SECTION 3.2.  Sale of Bonds and Deposit of Proceeds.  In order to
          provide funds for the prepayment of a portion of the KeySpan Notes and
          the  redemption of a part of the Prior Bonds,  the  Authority,  on the
          date specified in the Bond Purchase Agreement or as soon thereafter as
          practicable,  and  concurrently  with the issuance and delivery to the
          Trustee of the Note as provided  in Section  4.1  hereof,  will issue,
          sell and  deliver  the Bonds,  all  pursuant to and as provided in the
          Bond  Purchase  Agreement and subject to the  conditions  set forth in
          Section 2.06 of the  Indenture,  and will deposit the proceeds of such
          sale paid by the initial purchasers of the Bonds in the Project Fund.

               SECTION 3.3.  Disbursements from Project Fund and Rebate Fund. 1.
          The Authority has in the Indenture authorized and directed the Trustee
          to make payments from the Project Fund in accordance with Section 8.01
          of the  Indenture,  to pay the  Prepayment  Price  and  costs  related
          thereto and the refunding of the Prior Bonds upon receipt from time to
          time of requisitions  signed by an Authorized Company  Representative,
          stating  with  respect  to each  payment  to be made  the  information
          required by Section 8.01 of the  Indenture.  Amounts on deposit in the
          Rebate Fund shall be  disbursed  in  accordance  with the terms of the
          Indenture and the Tax Regulatory Agreement.

               The Company will cause such  requisitions  to be submitted to the
          Trustee as may be necessary to effect payments out of the Project Fund
          in accordance with the provisions of the Indenture.

               Concurrently with the delivery by the Company of each requisition
          to the Trustee,  the Company  will deliver to the  Authority a copy of
          such  requisition and any attachments  thereto.  The Authority and the
          Trustee may rely as to the completeness and accuracy of all statements
          in such  requisition  and the Company will indemnify and save harmless
          the  Authority  and  the  Trustee  from  any  liability   incurred  in
          connection  with any requisition so delivered and any payments made in
          reliance thereon.

               2.  Except for  amounts  retained  by the  Trustee at the written
          direction of an Authorized Company Representative for payment of items
          not then due and  payable  or the  liability  for  payment of which is
          being  contested or disputed by the Company,  all monies  remaining in
          the Project Fund (but not the Rebate Fund) after the redemption of the
          Prior Bonds and payment of all costs  related  thereto  shall,  at the
          written direction of an Authorized Company Representative,


                                       -7-


<PAGE>



be applied in  accordance  with  Section  8.01.6 of the  Indenture.  Any balance
remaining of such  retained  amounts to the extent not  disbursed in  accordance
with  subsection  1 above,  shall,  at the written  direction  of an  Authorized
Company Representative, be similarly applied.

               SECTION 3.4.  Adequacy of Project Fund.  The monies which will be
          paid  into  the  Project  Fund  will  not be  sufficient  to  pay  the
          Prepayment  Price and costs  related  thereto and the refunding of the
          Prior  Bonds.  The Company  shall pay that  portion of the  Prepayment
          Price and costs  related  thereto and the refunding of the Prior Bonds
          in  excess of the  monies  available  therefor  in the  Project  Fund.
          Without  limiting the  generality  of the  foregoing,  the Company has
          agreed and hereby agrees to prepay the $4,557,681.25  principal amount
          of the KeySpan  Notes,  representing a portion of the principal of the
          Series A Bonds applied to the payment of costs of  facilities  located
          at the former  Shoreham  Nuclear Power Station and the former Mitchell
          Gardens  Power  Station.  The  Company  shall not be  entitled  to any
          reimbursement  therefor from the Authority,  the Trustee or the owners
          of any of the Bonds,  nor shall it be entitled to any diminution in or
          postponement  of the  payments  required  to be  paid  by the  Company
          pursuant to this Participation Agreement or the Note.

               SECTION 3.5. Ownership and Possession of the Project. Issuance of
          the  Bonds  will not vest in the  owners  thereof,  the  Trustee,  the
          Authority  or any  other  person,  with  ownership,  or the  right  to
          possession,  of the  Project.  The  Company  is  entitled  to sole and
          exclusive ownership and possession of the Project.

               SECTION 3.6. Operation, Maintenance and Repair. The Authority and
          the Company recognize that the Project constitutes integrated portions
          of the electric energy  production  facilities of the Company and that
          it is not  feasible to  administer  the Project  separately  from such
          facilities.  The Company shall operate the Project (with such changes,
          improvements  or additions as the Company may deem  desirable) as part
          of such  facilities  for the joint useful life of the Project and such
          facilities,  shall maintain and repair the Project in conformity  with
          the  Company's  normal   maintenance  and  repair  programs  for  such
          facilities   and  shall   proceed  in  good  faith  to  maintain   the
          availability of the Project for use as an authorized project under the
          Act; but the Company shall have no obligation to operate,  maintain or
          repair any element or item of the Project the operation,  maintenance,
          or repair of which becomes uneconomic to the Company because of damage
          or destruction or  obsolescence  (including  physical,  functional and
          economic   obsolescence),   or  change  in  government  standards  and
          regulations,  or the  termination  of the  operation of the portion of
          such  facilities  to which the  element  or item of the  Project is an
          adjunct.

               SECTION 3.7.  Investment of Monies in Funds Under the  Indenture.
          Any  monies  held as a part of any fund  created  under the  Indenture
          shall, at the direction of an Authorized  Company  Representative,  be
          invested or reinvested by the Trustee as provided in Article IX of the
          Indenture.

                                NOTE AND PAYMENTS

               SECTION  4.1.   Execution   and  Delivery  of  Note  to  Trustee.
          Concurrently with the authentication by the Registrar and Paying Agent
          and  delivery by the  Authority  of the Bonds and in order to evidence
          the obligation of the Company to the Authority to repay the Bonds, the
          Authority  hereby directs the Company,  and the Company hereby agrees,
          to execute  and  deliver to the  Trustee  its Note,  duly and  validly
          executed and  delivered,  relating to the Bonds.  The Note shall be in
          substantially  the form  attached  hereto as  Exhibit C with only such
          changes to such form as may be approved by the Authority.  Thereafter,
          the Company shall be obligated to make the Note Payments, constituting
          payments of  principal  of, and  premium,  if any, and interest on the
          Note,  and the  Additional  Payments  required  by this  Participation
          Agreement.  Such obligations shall terminate on the date when the Note
          has been paid in full.  The Note may be  prepaid  in  accordance  with
          Section 4.4 hereof.  Upon payment or provision  for payment in full of
          all amounts  payable or to become  payable under the Note, the Trustee
          shall cancel the Note and deliver the same to the  Company.  Provision
          for payment in full of all amounts  payable or to become payable under
          the Note shall be deemed to have  occurred upon receipt by the Trustee
          of written  notice from the Authority  acknowledging  that the Company
          has satisfied its  obligations  to the Authority  under the Note.  The
          Authority  agrees  to  deliver  such  written  notice  to the  Trustee
          promptly when such provision for payment in full has been made.

               SECTION  4.2.   Payments  Payable;   Note  Payments;   Additional
          Payments.  (a) The Company covenants and agrees to pay the Payments as
          and when the same are due and payable in accordance  with the Note and
          this Section 4.2. The Company shall provide the Trustee with a written
          allocation  of amounts  paid under this  Section 4.2 among the various
          purposes set forth in this Section 4.2.

               (b) The Note Payments shall be in an aggregate amount  sufficient
          for,  together  with other  amounts held by the Trustee and  available
          under the  Indenture  for  application  to, the payment in full of the
          Bonds consisting of (i) the total interest becoming due and payable on
          the Bonds to the date of payment thereof, and (ii) the total principal
          amount plus premium, if any, of the Bonds.

               The  Company  covenants  that it  shall  deposit,  or cause to be
          deposited with the Trustee, sufficient funds to assure that no default
          shall occur in the payment of the principal of or premium,  if any, or
          the  interest on the Bonds as and when due,  and that no  unreasonable
          delay  shall occur in the  payment of the costs and  expenses  payable
          from Additional Payments.

               (c) The Company shall make Note Payments by 12:00 noon,  New York
          City time, one Business Day (two Business Days during any Auction Rate
          Period or any Auction Rate- Inverse Rate Period) next  preceding  each
          Interest  Payment  Date to the Bond Fund for credit by the  Trustee to
          the Interest Account of the Bond Fund established  pursuant to Section
          9.01 of the

Indenture, in the aggregate amount required, together with other funds available
therefor in the Interest  Account in the Bond Fund, to pay the interest  payable
on each such Outstanding Bond on each such Interest Payment Date.

               In addition,  the Company shall pay an  additional  amount to the
          Trustee  for  deposit  in the Bond Fund and  credit  to the  Principal
          Account,  Interest Account,  Redemption  Account or to the Trustee for
          payment to, or directly to, the Registrar and Paying Agent for deposit
          in the Bond Purchase Fund and credit to the Company Account therein to
          be applied to the payment of the principal of and premium, if any, and
          interest  payable upon redemption of any Bond pursuant to Article V of
          the  Indenture  or  purchase  price of any Bond  pursuant  to the Bond
          Purchase  Trust  Agreement to the extent not provided from the sources
          described therein.

          Conversion Date to the extent a Liquidity  Facility is in place and to
          the extent  necessary to maintain or obtain any short term rating with
          respect to the Bonds,  monies  provided  by the  Company  shall not be
          applied to the payment of the purchase  price,  until any such amounts
          have been on  deposit  in the  applicable  account  for a period of at
          least 124 days and the Company shall have delivered a Non-  Bankruptcy
          Certificate to the Trustee in accordance with the Indenture. If and to
          the extent such  monies are not  available  and there is no  Liquidity

          principal of, premium, if any, and interest on, and the Purchase Price

           Agreement, and the Indenture; and

                     (iv) an  administration  fee of the Authority in the amount
           of  $102,812.50  paid to the Authority on the date of  authentication
           and delivery of the Bonds and an annual fee equal to $130 per million
           dollar  principal  amount  of the  Bonds on  October  1 of each  year
           commencing   October  1,  2000,   based  upon  the  amount  of  Bonds
           Outstanding as of such October 1 and for purposes of the  calculation
           of such fee,  rounding up to the nearest whole million  dollars,  and
           all reasonable expenses, disbursements,  advances, taxes, assessments
           or impositions, not otherwise paid under this Participation Agreement

           connection with its administration and enforcement of, and compliance
           with, this Participation Agreement, the Auction Agency Agreement, the
           Bond Purchase  Trust  Agreement,  the Market Agent  Agreement and the
           Indenture,  which amounts the Company is obligated to pay, including,
           but not limited to,  reasonable  attorneys'  fees.  In addition,  the
           Company  shall pay to the State of New York with respect to the Bonds
           a bond issuance  charge in the amount of  $143,937.50  on the date of
           authentication and delivery of the Bonds.

               (f) In the event that the Company  shall fail to make any Payment
          as required by Sections  4.2(a),  (b),  (c),  (d) and (e) hereof,  the
          Payment so in default  shall  continue as an obligation of the Company
          until the  amount in  default  shall  have been  fully  paid,  and the
          Company agrees to pay the same with interest  thereon,  which interest
          shall also constitute an obligation of the Company at the maximum rate
          of interest  payable on the Bonds  pursuant to the  Indenture,  to the
          extent  permitted  by law,  from  the  date  of  default  until  paid;
          provided,  that the Company agrees in the event the Company shall fail
          to make any  Payment  during an  Auction  Rate  Period  or an  Auction
          Rate-Inverse Rate Period,  the Payment so in default shall continue as
          an  obligation  of the Company  until the amount in default shall have
          been fully paid,  and the Company agrees to pay the same with interest
          thereon,  which  interest  shall also  constitute an obligation of the
          Company at, in the case of an Auction Rate Period, the Maximum Auction
          Rate,  and in the case of an Auction  Rate-Inverse  Rate  Period,  the
          Overdue Rate, to the extent permitted by law, from the date of default
          until paid.  Nothing in this Section 4.2 shall  require the Company to
          pay costs and expenses  mentioned in clause  (e)(iii) above so long as
          the validity or the reasonableness  thereof shall be contested in good
          faith  unless the  Trustee  shall  receive  an opinion of  independent
          counsel  that  such  contest  materially  jeopardizes  the  respective
          interests  of the  Authority  and the  Trustee  in this  Participation
          Agreement,  the Auction  Agency  Agreement,  the Bond  Purchase  Trust
          Agreement, the Indenture or the Market Agent Agreement, in which event
          the Company  shall pay such costs and expenses  (without  prejudice to
          any rights of the  Company to recover  such costs and  expenses if not
          valid or reasonable)  to the end that the respective  interests of the
          Authority and the Trustee, in the opinion of independent  counsel, are
          not materially jeopardized.

          intend  or will be  unable to make the  corresponding  payment  to the
          Trustee under the Note.

               SECTION  4.3.  Notice to Pay;  Medium of  Payment;  Acceleration.
          Failure to  receive  any prior  notice of the due date of any  Payment

          when it is due and payable.  The Company  covenants and agrees that it
          will pay or  cause  to be paid  when  due and  payable  hereunder  the

          nature whatsoever, in lawful money of the United States of America.

               If pursuant to the  provisions of Section 12.03 of the Indenture,
          the  obligation  of the Authority to pay the Bonds is  accelerated  or
          shall  otherwise  be declared  due and payable  immediately,  then the
          Company  shall  forthwith  pay or cause to be paid to the  Trustee  an

          Bonds in full and, secondly an amount which shall be sufficient,  with
          all other funds available  therefor,  to pay all other  obligations of
          the  Authority  or the Company  incurred  or to be incurred  under the
          Indenture, this Participation Agreement, the Auction Agency Agreement,
          the Bond Purchase Trust Agreement or the Market Agent Agreement.

               SECTION 4.4. Advance Payments.  The Company shall have the option
          from time to time in conjunction with the redemption of Bonds pursuant
          to  Section  5.01 or 5.04 of the  Indenture  to pay to the  Trustee in
          advance of the time required by this  Participation  Agreement and the
          Note for deposit in the Bond Fund for credit to the Redemption Account
          therein  such  amounts as the Company may elect in order to effect the
          prepayment  of the Note in whole or in part.  The  Company  shall give
          notice to the Trustee and the Authority of any intention to prepay the
          Note in whole or in part and of the principal amount to be prepaid not
          more than sixty (60) nor less than  thirty-five (35) days prior to the
          date on which such  Payment is to be made on the Note.  Such  optional
          prepayment  may be made not later than one (1)  Business  Day prior to
          the date of prepayment of the Bonds.

               SECTION 4.5. Company's Payments as Trust Funds. All Note Payments
          and Additional  Payments required to be made by the Company under this
          Participation Agreement and the Note to the Authority,  the Trustee or
          the  Registrar and Paying Agent which under the Indenture are required
          to be applied in payment of or as security for the Bonds, shall be and
          constitute and are hereby declared to be trust funds,  whether held by
          the  Authority,  the Trustee,  the Registrar and Paying Agent,  or any
          bank or trust company,  designated for such purpose and shall continue
          to be  impressed  with a trust  until such  monies are  applied in the
          manner provided in the Indenture.

               SECTION 4.6. Absolute Obligation to Make Payments. The obligation
          of the Company to pay the Note Payments and the  Additional  Payments,
          as required by this Participation

extent  whatsoever  (other than for prior payment),  regardless of any rights of
set-off,  recoupment  or  counterclaim  that the Company  might  otherwise  have
against  the  Authority  or the  Trustee  or any  other  party  or  parties  and

                    exercise of the power of eminent domain or otherwise;

           (c)       any assignment,  novation, merger, consolidation,  transfer
                     of assets,  subleasing or other similar  transaction  of or
                     affecting the Company  whether with or without the approval
                     of the Trustee,  except as otherwise  expressly provided in
                     this Participation Agreement;

           (d)       with respect solely to the obligation of the Company to pay
                     the Additional Payments,  the termination of this Agreement
                     and payment or provision  for payment in full of the amount
                     due under the Note pursuant to the provisions hereof;

           (e)       any  failure  of  any  party  to  perform  or  observe  any
                     agreement or covenant,  whether express or implied,  or any
                     duty,   liability  or  obligation  arising  out  of  or  in
                     connection with this Participation Agreement, the Note, the
                     Auction Agency Agreement,  any Broker-Dealer Agreement, the
                     Market Agent  Agreement,  the Bond Purchase Trust Agreement
                     or the Indenture;

               (f) any  change  or  delay  in the  time of  availability  of the
          Project  or any  part  thereof  for  use of the  Project  or any  part
          thereof;

               (g) any acts or circumstances  that may constitute an eviction or
          constructive eviction from any part of the Project;

provided,  however, that the foregoing shall not be deemed to be a waiver of any
right of recourse the Company may have against the Authority,  the holder of any
Bond or others,  including  but not limited to, the rights,  causes of action or
claims which may arise out of the breach of their respective  obligations or the
inaccuracy of their respective warranties,  provided,  however, that the Company
may  pursue  any  such  right,  claim  or cause  of  action  only by a  separate
proceeding  or action  and not by  counterclaim  or  set-off  hereunder  and the
bringing of such  separate  proceeding  or action shall not affect the Company's
absolute,  irrevocable and unconditional obligation to make payments pursuant to
this Section 4.6.

               However,  the  obligation  of the  Company to make Note  Payments
          shall be deemed satisfied when made or to the extent the Trustee makes
          the deposits in the Bond Fund for credit to the Principal  Account and
          Interest   Account   from   the   sources    described   in   Sections
          9.02(a)(ii)(II) and 9.02(b)(ii)(I) and (III) of the Indenture.

               SECTION 4.7.  Assignment of Authority's  Rights.  As security for
          the  payment of the Bonds,  the  Authority  will assign to the Trustee
          certain of the Authority's rights under this  Participation  Agreement
          and the  Note,  including  the  right to  receive  payments  hereunder
          (except  the  right  to  receive  payments,  if  any,  under  Sections
          4.2(e)(ii)  and (iv),  5.16 and 7.4  hereof and the right to amend the
          Participation  Agreement)  and hereby directs the Company to make said
          payments  directly to the Trustee or in the case of the Purchase Price
          to the  Registrar and Paying Agent.  The Company  herewith  assents to
          such  assignment  and will  make  payments  under  this  Participation
          Agreement  and the Note  (except  payments  made  pursuant to Sections
          4.2(e)(ii) and (iv),  5.16 and 7.4 hereof which shall be made directly
          to the  Authority)  directly  to the  Trustee  (or in the  case of the
          Purchase  Price, to the Registrar and Paying Agent) without defense or
          set-off  by reason of any  dispute  between  any of the  Company,  the
          Trustee or Registrar and Paying Agent.

               SECTION  4.8.  Actions  with respect to or by or on behalf of the
          Authority under the Indenture.  The Authority  hereby grants the right
          to the Company to request the Authority to take certain  actions under
          the  Indenture  and/or to  perform  or  undertake  certain  actions as
          specified  under the  Indenture.  The  Company  agrees to request  the
          Authority to take action or undertake or perform any action  solely in
          compliance  with  or  after  complying  with  the   requirements   and
          provisions of the Indenture.

               SECTION   4.9.   Agreements   of  Company   relating  to  Support
          Facilities.  In order to secure the  payment of interest on the Bonds,
          the Company has obtained a Credit Facility.  The Company agrees not to
          request  that an  Adjustable  Rate other than an Auction Rate during a
          Auction  Rate Period or an Auction  Rate and an Inverse Rate during an
          Auction  Rate-Inverse  Rate Period become effective unless there shall
          be in effect,  prior to the  applicable  Change in the  Interest  Rate
          Mode, a Liquidity  Facility which meets the requirements of Article VI
          of the Indenture.

               The Company  further  agrees that it will  maintain at all times,
          except during any Auction Rate Period,  an Auction  Rate-Inverse  Rate
          Period or the Fixed Rate Period, a Liquidity


                                      -14-

Facility shall expire no earlier than the earliest of (1) its stated  expiration
date,  which shall be not less than six months from its effective date and shall
be no earlier than the second  Business Day after the next  succeeding date when
Bonds are subject to optional or  mandatory  tender for  purchase,  (2) when all
available amounts have been drawn and not been timely reimbursed, (3) the second
business  day  following a Change in the  Interest  Rate Mode to an Auction Rate
during an Auction Rate Period or an Auction Rate during and Auction Rate-Inverse
Rate Period,  (4) the second  business day following  the Fixed Rate  Conversion
Date,  (5) on the  effective  date  of any  Alternate  Liquidity  Facility  that
replaces the then effective Liquidity  Facility,  (6) the earliest date on which
no Bonds are outstanding  and (7) twelve days after the Trustee  receives notice
from the Liquidity Facility Issuer that it is terminating the Liquidity Facility
and directing the Trustee to cause a mandatory tender and purchase of the Bonds.

               SECTION  4.10.  Project not Security  for Bonds.  It is expressly
          recognized  by the parties  that the Project will not  constitute  any
          part of the security  for the Bonds.  The  principal  security for the
          Bonds   shall  be  the  Note  and  the   absolute,   irrevocable   and
          unconditional obligation of the Company to make the Note Payments.

               SECTION 5.1. No Warranty as to  Suitability  of the Project.  The
          Authority makes no warranty,  either express or implied,  with respect
          to actual or designed  capacity of the Project,  as to the suitability
          of the  Project  for the  purposes  specified  in  this  Participation
          Agreement,  as to the  condition of the  Project,  or that the Project
          will be suitable for the Company's purposes or needs.

               SECTION 5.2.  Authority's Rights to Inspect the Project and Plans
          and  Specifications.  The  Authority  shall  have  the  right  at  all
          reasonable  times to examine  and  inspect  the  Project to the extent
          practicable and, to the extent reasonably available,  the construction
          plans and specifications therefor.

               SECTION  5.3.  Company  Consent to Amendment  of  Indenture.  The
          Authority  shall  not  enter  into any  indenture  supplemental  to or
          amendatory of the Indenture which affects the rights or obligations of
          the Company without the prior consent of the Company as evidenced by a
          certificate in writing signed by an Authorized Company Representative.

                    SECTION  5.4.  Tax  Covenant.   Notwithstanding   any  other
               provision  hereof,  the Company covenants and agrees that it will
               not take or authorize  any action or permit any action within its
               reasonable control to be taken, or fail to take any action within
               its  reasonable  control,  with  respect to the  Project,  or the
               proceeds of the Bonds,  including any amounts treated as proceeds
               of the Bonds for any  purpose  of  Section  103 of the Code,  the
               taking of which or any failure to so take will result in the loss
               of the  exclusion  of interest on the Bonds from gross income for
               federal income tax purposes under Section 103 of the Code (except
               for any Bond  during any period  while any such Bond is held by a

               "related  person" in Section 147(a) of the Code).  This provision
               shall  control in case of  conflict or  ambiguity  with any other
               provision of this Participation Agreement. In furtherance of such
               covenant  and  agreement,  the  Authority  and the  Company  have
               entered into the Tax Regulatory  Agreement and the Company hereby
               covenants and agrees to comply with the provisions thereof.

                    SECTION 5.5.  Maintenance  of Office or Agency.  The Company
               will at all  times  keep,  in  Brooklyn,  New  York,  or  another

               companies  similarly  situated and operating like properties,  to
               the extent that  property  of similar  character  is  customarily

               applicable   laws,  rules  and  regulations  and  orders  of  any

               material adverse effect on its business,  financial  condition or
               results of  operations  (to the extent the  Company  deems it can
               reasonably   comply   while   maintaining   its  public   utility
               operations) or would  materially  adversely  affect the Company's

               Agreement or under the Note, except laws,  rules,  regulations or

                    Nothing  contained  in this  Participation  Agreement  shall
               prevent (and this  Participation  Agreement shall be construed as

               company formed by such  consolidation,  or into which such merger
               may be made if other than the  Company,  or the company  which is
               acquiring or  purchasing  the Company,  or which is a transferee,
               shall execute and deliver to the Trustee and the Credit  Facility
               Issuer  an  instrument,  in  form  satisfactory  to the  Trustee,

               to and be  substituted  for the Company  hereunder  and under the
               Note, with the same effect as if such successor  company had been
               named herein as obligor.

               pledges  and  charges of the  Indenture  or furnish an opinion of
               counsel (which may be counsel to the Company) stating that in the
               opinion of such  counsel no action is required  to maintain  such
               assignments, liens, pledges and charges.

                    SECTION 5.18.  Provision of  Information.  The Company shall
               provide the Trustee with the forms of any notices  required to be
               sent to holders of Bonds in  connection  with any  redemption  of
               Bonds,  a change in the Auction  Period,  the Interest  Period or
               change in the Interest Rate Mode pursuant to Articles III, III-A,
               IV and V of the Indenture or the establishment of a Fixed Rate on
               the Bonds pursuant to Section 4.02 of the Indenture.

                    SECTION 5.19. Ratings. During any Auction Rate Period or any
               Auction Rate  Inverse  Rate Period,  the Company on behalf of the
               Authority shall take all reasonable action necessary to enable at
               least two nationally recognized, statistical rating organizations
               (as  that  term is  used  in the  rules  and  regulations  of the
               Commission  under the  Exchange  Act) to provide  ratings for the
               Auction  Rate  Bonds  during an  Auction  Rate  Period or Auction

               book-entry form by the Securities Depository,  the Auction Agent,

                         EVENTS OF DEFAULT AND REMEDIES

                    SECTION 7.1. Events of Default Defined.  The following shall
               be an "Event of Default" under this  Participation  Agreement and
               the terms  "Event of Default" or "Default"  shall mean,  whenever
               they are used in this Participation Agreement, any one or more of
               the following events:

                     (a) Failure by the Company to pay or cause to be paid, when
           due and payable, any installment of Note Payments and, in the case of
           failure to pay any  installment of interest on the Note,  continuance
           of such failure for three (3) Business Days.

                     (b)  Failure  by the  Company to observe  and  perform  any
           covenant,  condition or agreement in this Participation  Agreement or
           the Note on its  part to be  observed  or  performed,  other  than as
           referred  to in  subsection  (a) of this  Section 7.1 (and other than
           failure to pay the amounts due under Sections  4.2(e),  4.2(f),  5.16
           and 7.4 of this Participation Agreement), for a period of ninety (90)
           days after written  notice,  specifying  such failure and  requesting
           that it be remedied, has been given to the Company unless the Trustee
           (with any required consent of Bondholders under the provisions of the
           Indenture)  shall agree in writing to an extension of such time prior
           to its  expiration,  provided  that if any such failure shall be such
           that it cannot be cured or corrected  within such ninety-day  period,
           it shall not constitute an Event of Default  hereunder if curative or
           corrective  action is  instituted  within such period and  diligently
           pursued until the failure of performance is cured or corrected.

                     (c) The  dissolution  or  liquidation of the Company or the
           filing by the  Company of a  voluntary  petition  in  bankruptcy,  or
           failure  by  the  Company  promptly  to  discharge  or  cause  to  be
           discharged   any   execution,   garnishment  or  attachment  of  such
           consequence  as will  impair its  ability to carry on its  operations
           generally or the  commission by the Company of any act of bankruptcy,
           or  adjudication  of the Company as a bankrupt,  or assignment by the
           Company for the benefit of its creditors, or the entry by the Company
           into an agreement of compromise  with its creditors,  or the approval
           by a court of competent  jurisdiction of a petition applicable to the
           Company in any proceeding for its reorganization instituted under the
           provisions of the federal  bankruptcy laws. The term  "dissolution or
           liquidation of the Company", as used in this subsection, shall not be
           construed to include the cessation of the limited  liability  company
           existence  of  the  Company   resulting   either  from  a  merger  or
           consolidation  of  the  Company  into  or  with  another  company  or
           corporation or a dissolution or liquidation of the Company  following
           a transfer of all or substantially  all of its assets as an entirety,
           under the  conditions  permitting  such  action  with  respect to the
           Company contained in Section 5.12 hereof.

                    (d) The  occurrence  of an event of  default  as  defined in
               Section 12.01 of the Indenture.

                    Subsection  (b)  of  this  Section  7.1  is  subject  to the
               following limitations:  Except for the obligations of the Company
               contained  in Article IV and  Article VI hereof,  if by reason of
               force  majeure the Company is unable in whole or in part to carry
               out the  agreements  on its part  herein  contained,  the Company
               shall not be deemed in  default  during the  continuance  of such
               inability.  The term "force majeure" as used herein shall include
               the following: acts of God; strikes, lockouts or other industrial
               disturbances;  acts of public enemies;  orders of any kind of the
               government  of the  United  States or of the State of New York or
               any of their departments, agencies, or officials, or any civil or
               military authority;  insurrections; riots; epidemics; landslides;
               lightning;  earthquake; fire; typhoons; storms; floods; washouts;
               droughts;  arrests; civil disturbances;  explosions;  breakage or
               accident to machinery,  transmission pipes or canals;  partial or
               entire  failure  of  utilities;  or any other  cause or event not
               reasonably within the control of the Company. The Company agrees,
               however,  to remedy  with all  reasonable  dispatch  the cause or
               causes  preventing the Company from carrying out its  agreements;
               provided,  that the  settlement  of strikes,  lockouts  and other
               industrial  disturbances  shall be entirely within the discretion
               of the  Company,  and the  Company  shall not be required to make
               settlement of strikes, lockouts and other industrial disturbances
               by acceding to the demands of the opposing  party or parties when
               such course is in the judgment of the Company  unfavorable to the
               Company.

                    SECTION  7.2.  Remedies on Default.  In the event any of the
               Bonds shall at the time be  Outstanding  and unpaid and provision
               for the payment  thereof  shall not have been made in  accordance
               with the  provisions  of the  Indenture,  whenever  any  Event of
               Default referred to in Section 7.1 hereof shall have happened and
               be existing, the Authority or the Trustee, following acceleration
               of the Bonds in  accordance  with  provisions of Section 12.03 of
               the Indenture where so provided,  may take any one or more of the
               following remedial steps:

                     (a)  The  Authority  or  the  Trustee  as  provided  in the
           Indenture may, at its option, with the consent of the Credit Facility
           Issuer,  or shall, to the extent  required by the Indenture,  declare
           all payments  payable  under  Section 4.2 hereof and the Note for the
           remainder  of  the  term  of  this  Participation   Agreement  to  be
           immediately  due  and  payable,   whereupon  the  same  shall  become
           immediately due and payable.

                     (b) The  Trustee,  with the  written  consent of the Credit
           Facility  Issuer,  may take whatever  action at law or in equity that
           may appear necessary or desirable to collect the amounts then due and
           thereafter to become due, or to enforce performance and observance of
           any  obligation,  agreement  or covenant  of the  Company  under this
           Participation  Agreement or the Note whether for specific performance
           of any covenant or agreement contained herein or therein or in aid of
           the execution of any power herein granted.

               Any amounts collected pursuant to action taken under this Section
               7.2 shall be paid into the Bond Fund and  applied  in  accordance
               with the provisions of the Indenture.

                         If any such  declaration of  acceleration  of the Bonds
                    shall  have  been  annulled  pursuant  to the  terms  of the
                    Indenture  and if, at any time after such  declaration,  but
                    before all the Bonds shall have matured by their terms,  all
                    arrears of interest  upon the Note,  and interest on overdue
                    installments  of interest (to the extent  enforceable  under
                    applicable law) at the rate or rates per annum specified for
                    the Note and the  principal of and  premium,  if any, on the
                    Note which shall have become due and payable  otherwise than
                    by  acceleration,  and all  other  sums  payable  hereunder,
                    except the  principal  of, and  interest  on, the Note which
                    pursuant  to such  declaration  shall  have  become  due and
                    payable, shall have been paid by or on behalf of the Company
                    or  provision  satisfactory  to the Trustee  shall have been
                    made for such payment,  then such  acceleration  of the Note
                    shall  ipso  facto be  deemed to be  rescinded  and any such
                    Default and its  consequences  shall ipso facto be deemed to
                    be annulled, but no such annulment shall extend to or affect
                    any  subsequent  Default or impair or  exhaust  any right or
                    remedy consequent thereon.

                         SECTION  7.3.  No Remedy  Exclusive.  No remedy  herein
                    conferred  upon  or  reserved  to  the  Authority  or to the
                    Trustee is intended to be exclusive  of any other  available
                    remedy or remedies,  but each and every such remedy shall be
                    cumulative  and shall be in addition  to every other  remedy
                    given under this Participation Agreement or now or hereafter
                    existing  at law or in  equity  or by  statute.  No delay or
                    omission to exercise  any right or power  accruing  upon any
                    Default  shall  impair  any such  right or power or shall be
                    construed  to be a waiver  thereof,  but any such  right and
                    power may be exercised from time to time and as often as may
                    be deemed  expedient.  In order to entitle the  Authority or
                    the  Trustee to exercise  any remedy  reserved to it in this
                    Article, it shall not be necessary to give any notice, other
                    than such notice as may be herein expressly  required.  Such
                    rights and  remedies  as are given the  Authority  hereunder
                    shall also  extend to the  Trustee  and the  Trustee and the
                    Holders of the Bonds  issued  under the  Indenture  shall be
                    deemed  third  party  beneficiaries  of  all  covenants  and
                    agreements herein contained.

                         In case the Trustee (as assignee of the Authority under
                    the  Indenture)  or the  Authority  shall have  proceeded to
                    enforce its rights under this  Participation  Agreement  and
                    such proceedings  shall have been  discontinued or abandoned
                    for any reason or shall have been  determined  adversely  to
                    the Trustee or the  Authority,  then and in every such case,
                    the Company, the Authority and the Trustee shall be restored
                    respectively   to  their   several   positions   and  rights
                    hereunder,  and  all  rights,  remedies  and  powers  of the
                    Company,  the Authority  and the Trustee  shall  continue as
                    though no such proceeding had been taken.

                         The Company covenants that, in case an Event of Default
                    shall occur with respect to any Note Payments  payable under
                    Sections 4.2(a), (b) and (c) hereof and the Note, then, upon
                    demand of the Trustee (as  assignee of the  Authority  under
                    the  Indenture),  the  Company  will pay to the  Trustee the
                    whole  amount  that then shall have  become due and  payable
                    under said Sections,  with interest (to the extent permitted
                    by law) on said amount at the rate of interest then borne by
                    the Bonds pursuant to the  Indenture,  but not exceeding the
                    maximum rate  permitted by law,  until paid, and in addition
                    thereto,  such  further  amounts as shall be  sufficient  to
                    cover  the  costs  and  expenses  of  collection,  including
                    reasonable   compensation   to  the  Trustee,   its  agents,
                    attorneys,

                         and  counsel,  and any other  expenses  or  liabilities
                    incurred by the Trustee  other than those  incurred  through
                    bad faith or negligence.

               In case the Company shall fail forthwith to pay such amounts upon
               such  demand,  the  Authority  or the Trustee (as assignee of the
               Authority under the Indenture) shall be entitled and empowered to
               institute  any action or  proceeding  at law or in equity for the
               collection  of the sums so due and unpaid,  and may prosecute any
               such action or proceeding  to judgment or final  decree,  and may
               enforce any such judgment or final decree against the Company and
               collect, in the manner provided by law out of the property of the

                    Required.  To the extent the consent,  approval or direction
                    of the Credit  Facility  Issuer is required by any provision
                    of this Participation  Agreement, the Credit Facility Issuer
                    shall  have  the  right  to  give,  and  the  discretion  to
                    withhold,  such consent,  approval or direction  only if (i)
                    the Credit  Facility  Issuer is not party to any  proceeding
                    for  the   rehabilitation,   liquidation,   conservation  or
                    dissolution of the Credit  Facility  Issuer  pursuant to the
                    U.S. Bankruptcy Code or similar provision of State law; (ii)
                    the Credit  Facility is in full force and effect;  (iii) the

                    make all payments and meet all of its obligations  under the
                    Credit  Facility;  and (iv) any Bonds  insured by the Credit
                    Facility Issuer remain outstanding;  provided, however, that
                    Bonds  held by or for the  account of the  Company  shall be
                    deemed outstanding for purposes of this section and provided
                    further that nothing  contained in this Section shall affect
                    any rights that the Initial Credit  Facility Issuer may have
                    as a bondholder by virtue of its rights of  subrogation.  So
                    long as those  conditions are met the Credit Facility Issuer
                    shall also be treated as a third party beneficiary hereunder
                    and as a party  entitled  to (i) notify  the  Trustee of the
                    occurrence  of an Event of  Default  and  (ii)  request  the
                    Trustee to intervene in judicial proceedings that affect the

                    Facility Issuer,  and the security  therefor;  provided that
                    the Trustee  shall be entitled to indemnity  from the Credit
                    Facility  Issuer  satisfactory  to it; and the Trustee shall
                    accept  notice  of an  Event  of  Default  from  the  Credit
                    Facility Issuer.

such Outstanding Bond on each such Interest Payment Date.

               In addition,  the Company shall pay an  additional  amount to the

               deemed to be  discharged  and this note shall be cancelled in the
               event  that the  Bonds  shall  have  been  accelerated  under the

               all amounts required under the Participation Agreement to be paid
               upon the occurrence of such acceleration.

               In the event the Company  should fail to make any of the payments
               required by this note or the  Participation  Agreement to be made
               to the  Authority,  the item or  installment  so in default shall
               continue  as an  obligation  of the  Company  until the amount in
               default shall have been fully paid, and the Company agrees to pay
               the same with interest  thereon at the rate of interest  borne by
               the Bonds,  to the extent,  but not  exceeding  the maximum rate,
               permitted by law,  until paid;  provided,  however,  that if such
               failure to pay results in a payment of principal  of, or premium,
               if any,  or  interest  on the Bonds  not being  made when due and
               payable,  the Company shall pay the same with  interest  thereon,
               which interest shall also constitute an obligation of the Company
               at the same rate of  interest  per annum as that  payable  on the
               Bonds;  provided,  further,  if during an Auction  Rate Period or
               Auction  Rate-Inverse Rate Period such failure results in payment
               of principal of, or premium, if any, or interest on Auction Bonds
               or the Auction Rate- Inverse Rate Bonds,  as the case may be, not
               being made when due and payable,  the Company  shall pay the same
               with interest  thereon,  which interest shall also  constitute an
               obligation of the Company, at the Overdue Rate.

               This note shall  finally  mature on October 1, 2028  unless  paid
               earlier  as  permittedby  the  Participation  Agreement  and  the

               of  principal  of,  premium,  if any, and interest due under this
               note or if any one or more of the events of default  specified in
               the Participation Agreement should occur, and if any such default
               is not remedied as provided in the Participation  Agreement,  the
               Authority or the Trustee  then,  or at any time  thereafter,  may
               give notice to the Company  declaring all unpaid  amounts of this
               note then  outstanding,  together  with all other unpaid  amounts
               outstanding under the Participation  Agreement, to be immediately

time in the  event of any  continuing  or  subsequent  default.  In the event of
default in the payment of this note,  the  undersigned  hereby agrees to pay all
costs incurred in connection with the collection of the amounts then due hereon,

               unconditional and shall not be abated, rebated, set off, reduced,
               abrogated, waived, diminished or otherwise modified in any manner
               or to any extent whatsoever other than for prior payment.

determination,  shall mean with  respect to Auction Rate Bonds during an Auction
Rate-Inverse  Rate  Period (i) the  interest  equivalent  of the 30-day  rate on

Paying Agent, the Credit Facility Issuer and the Company) by the Market Agent no
later than 12:00 noon (New York City time) on and as of such day as the  minimum
rate or rates of interest per annum which,  in the opinion of the Market  Agent,
taking into account the Calculation Period or Calculation Periods for the Bonds,
would be necessary on and as of such day to remarket Bonds in a secondary market
transaction at a price equal to the principal amount thereof; provided that such
rate or rates of interest  shall not exceed the lesser of 110% of the Commercial
Paper Rate Index on and as of such date and 15% per annum.

                  "Commercial  Paper Rate Index"  shall mean with respect to the

Agent on and as of such day.  If the  Bonds are rated by a Rating  Agency in its
highest  note or  commercial  paper  rating  category  or one of its two highest

are rated by a Rating Agency in a rating category that is lower than its highest
note or  commercial  paper  rating  category or its two highest  long-term  debt
rating  categories (and the Bonds are not rated in one of such categories by the
other Rating Agency), each Component Issuer must (a) have outstanding securities
rated by a Rating Agency in its note or commercial  paper rating  category which

setting the Commercial Paper Rate Index in the event any of the  above-described
methods are  determined by the  Authority to be  unavailable,  impracticable  or
unrealistic in the market place.  Upon the occurrence and during the continuance
of a Company  Downgrade  Event, the Bond Insurer shall have the right to consent
to any change to the  Component  Issuers and any change in the method of setting
the  Commercial  Paper  Rate  Index,  which  consent  shall not be  unreasonably
withheld.

the Interest Rate Mode, (b) the Fixed Rate  Conversion  Date or (c) the maturity
date of the Bonds.

                  "Commercial  Paper/Treasury Rate" on any date of determination
shall mean with  respect to Auction Rate Bonds during an Auction Rate Period (i)
in the case of any Auction Period of less than 180 days, the interest equivalent

corporate  bonds are rated  "AA" by S&P,  or the  equivalent  of such  rating by
Moody's or another  rating  agency,  as made  available  on a discount  basis or
otherwise  by the  Federal  Reserve  Board  for  the  Business  Day  immediately
preceding such date of  determination,  or in the event that the Federal Reserve
Board does not make available any such rate, then the arithmetic average of such
rates,  as quoted on a discount  basis or  otherwise,  by the  Commercial  Paper
Dealers,  to the Auction  Agent for the close of business  on the  Business  Day
immediately  preceding  such  date of  determination  or (ii) in the case of any
Auction Period of 180 days or more, the Treasury Rate for such Auction Period.

paper quotation or quotations furnished by the remaining Commercial Paper Dealer

Insurer after the occurrence and during the  continuance of a Company  Downgrade
Event; provided that such consent shall not be unreasonably withheld) to provide
such quotation or quotations  not being supplied by any Commercial  Paper Dealer
or Commercial  Paper  Dealers,  as the case may be, or if the Authority does not
select any such  Substitute  Commercial  Paper Dealer or  Substitute  Commercial
Paper  Dealers,  by the remaining  Commercial  Paper Dealer or Commercial  Paper
Dealers.  For purposes of this definition,  the "interest  equivalent" of a rate
stated on a discount basis (a "discount  rate") for commercial  paper of a given
day's  maturity  shall be equal to the product of (A) 100 times (B) the quotient
(rounded  upwards  to the next  higher  one-thousandth  (.001) of 1%) of (x) the
discount rate (expressed in decimals) divided by (y) the difference  between (1)
1.00 and (2) a  fraction  the  numerator  of which  shall be the  product of the

agency.

Upon the occurrence and during the continuance of a Company Downgrade Event, the

each  Calculation  Period during a Semi-annual  Rate Period,  a rate of interest
equal to the rate of interest per annum established and certified to the Trustee

principal  amount thereof;  provided that such rate of interest shall not exceed

in one of such  categories by the other Rating  Agency),  each Component  Issuer
must (a) have  outstanding  securities  rated by a Rating  Agency in its note or
commercial  paper  rating  category  which  is the same or  correlative,  in the
Indexing  Agent's  judgment,  to the note or commercial paper rating category or

                  SECTION  2.02.  Authorization  of  Bonds.  1.  There is hereby
created and  established  under this Indenture one issue of revenue bonds of the
Authority,  which shall be issued and designated as "Pollution Control Refunding
Revenue Bonds (KeySpan Generation LLC Projects), 1999 Series A" in the principal
amount of $41,125,000.  In order to distinguish  between Bonds which are subject
to  different  interest  rate  determination  methods and other  features and to
distinguish  the portion of the Bonds to be remarketed by any particular  Market
Agent,  the Bonds may be designated  and  redesignated  from time to time by the
Authority in such a way as to identify one or more subseries of the Bonds.  Such
subseries may be designated as subseries A-1 or subseries A-2,  subseries A-3 or
may be redesignated as subseries A-1-1, A-2-1, A-3-1, as the case may be, and so
forth.  Each  Bond  shall  bear  upon  the  face  thereof  such  designation  or
redesignation,  if any.  In the  event  any  series  of Bonds is  designated  or
redesignated  from time to time as one or more  subseries,  all  references to a
series of the Bonds in this Indenture shall refer to each such subseries  unless
the context otherwise requires.

                  2. The Bonds shall be secured by the assignments,  pledges and
charges made or created  herein for the payment and security of the Bonds and by
a lien on the Participation  Agreement (exclusive of the rights therein reserved
to the  Authority),  the proceeds of the Note, the Tax Regulatory  Agreement and
the other  monies,  rights,  properties  and  securities  from time to time held
hereunder,  subject only to the  provisions  of this  Indenture  permitting  the
application  of the  proceeds  of the  Bonds,  the Note and such  other  monies,
rights,  properties  and  securities  for  the  purposes  and on the  terms  and
conditions hereof, over and ahead of any claims,  encumbrances or obligations of
any nature hereafter arising or incurred.  The foregoing lien, pledges,  charges
and assignments shall be valid and binding from the time of the effectiveness of
this Indenture,  as set forth in Section 17.11, and the Note Payments made under
the Note and the  Participation  Agreement shall be immediately  subject thereto
upon receipt by the Trustee.

                  3. The Bonds are limited  obligations of the Authority payable
solely  from  payments  to be made by the  Company  pursuant to the Note and the
Participation  Agreement and the other  monies,  rights and  properties  pledged
hereunder including the proceeds of the Support Facility,  if any, obtained with
respect thereto and secured by a pledge from the Authority to the Trustee of the
Participation Agreement and the Note. The Bonds shall not be a debt of the State
of New York, and the State of New York shall not be liable thereon.

          4. The  covenants and  agreements  herein set forth to be performed by
     the  Authority  shall be for the benefit,  security and  protection  of any
     Holder of the Bonds and the Bond Insurer.

                  5. Neither the Trustee, the Bond Insurer nor any Holder of the
Bonds  shall be  required  to see that the  monies  derived  from such Bonds are
applied to the purpose or purposes for which such Bonds are issued.

                  6. The Bonds  shall be issued  under  this  Indenture  for the
purpose of (i) paying certain expenses  incurred in connection with the issuance
of the Bonds and (ii) prepaying the KeySpan Notes.

                  7. The Bonds bearing a Commercial  Paper Rate, a Daily Rate, a
Weekly  Rate  or  a  Monthly  Rate  shall  be  fully  registered  Bonds  in  the
denomination of $100,000 or any integral multiple thereof.  The Bonds bearing an
Auction  Rate during an Auction  Rate  Period or an Auction  Rate and an Inverse
Rate during an Auction  Rate-Inverse Rate Period shall be fully registered Bonds
in the  denomination  of $25,000 or any  integral  multiple  thereof.  The Bonds
bearing  a  Semi-annual  Rate,  a Term  Rate  or a Fixed  Rate  shall  be  fully
registered Bonds in the denomination of $5,000 or any integral multiple thereof.

                  8. The Bonds shall be numbered consecutively from AR-1 upwards
as issued,  or as otherwise  provided by the Registrar and Paying Agent.  If the
Bonds are  redesignated  to identify one or more  subseries,  the Bonds shall be
numbered in accordance with their subseries designation,  i.e. A-1-R-1,  A-2-R-1
or A-3-R-1, as the case may be. The Bonds shall mature on the Stated Maturity.

                  9. The Bonds  shall be  initially  issued in fully  registered
form,  without coupons,  and initially dated their date of first  authentication
and delivery. The Bonds shall initially be issued in the form of one global bond
registered in the name of the Securities Depository or its nominee and ownership
thereof shall be maintained in book entry form by the Securities  Depository for
the account of the Agent Members thereof.

                  10.  Upon any Change in the  Interest  Rate Mode to an Auction
Rate for an Auction  Rate Period or an Auction  Rate and an Inverse  Rate for an
Auction  Rate-Inverse  Rate  Period,  there shall be  Outstanding  an  aggregate
principal  amount of not less than (i) $20,000,000 for Auction Rate Bonds during
an  Auction  Rate  Period,  and (ii) at all times an equal  aggregate  principal
amount of Auction Rate Bonds and Inverse Rate Bonds and  $20,000,000 for Auction
Rate Bonds and Inverse Rate Bonds, respectively,  during an Auction Rate-Inverse
Rate Period and in the applicable denominations set forth in Section 2.02.7.

          SECTION  2.03.  Global  Form;  Securities  Depository.  1.  Except  as
     otherwise  provided in this Section 2.03, the Auction Rate Bonds during any
     Auction  Rate Period and the  Auction  Rate-Inverse  Rate Bonds  during any
     Auction Rate-Inverse Rate Period in the form of one

                                                       II-2

separate global bond for such series or subseries,  as the case may be, shall be
registered in the name of the Securities Depository or its nominee and ownership
thereof shall be maintained in book entry form by the Securities  Depository for
the account of the Agent Members thereof. The Authority may elect to issue Bonds
bearing a Fixed Rate or an  Adjustable  Rate other than an Auction  Rate (during
any Auction Rate  Period) or an Auction Rate and a related  Inverse Rate (during
any Auction Rate-  Inverse Rate Period),  in the form of one global bond of such
series  or  subseries,  as the  case  may  be,  registered  in the  name  of the
Securities  Depository or its nominee and ownership  thereof shall be maintained
in book entry form by the  Securities  Depository  for the  account of the Agent
Members thereof.

                  Except as provided in subsections  (3) and (4) of this Section
2.03,  the Auction  Rate Bonds  during any  Auction  Rate Period and the Auction
Rate-Inverse  Rate Bonds  during any  Auction  Rate-Inverse  Rate  Period may be
transferred,  in whole but not in part,  only to the Securities  Depository or a
nominee of the Securities  Depository,  or to a successor Securities  Depository
selected or  approved by the  Authority,  with the consent of the  Company,  the
Trustee,  the  Auction  Agent and the  Market  Agent,  or to a  nominee  of such
successor  Securities  Depository.  Each global certificate for the Auction Rate
Bonds and the  Inverse  Rate  Bonds  shall  bear a legend  substantially  to the
following  effect:  "Except  as  otherwise  provided  in  Section  2.03  of  the
Indenture,  this global bond may be transferred,  in whole but not in part, only
to the  Securities  Depository  as defined in the  Indenture or a nominee of the
Securities Depository or to a successor Securities Depository or to a nominee of
a successor Securities Depository."

                  2. The Authority,  the Company, the Trustee, the Registrar and
Paying Agent,  the Auction  Agent,  any Support  Facility  Issuer and the Market
Agent shall have no responsibility or obligation with respect to:

          (a) the accuracy of the records of the  Securities  Depository  or any
     Agent  Member  with  respect to any  beneficial  ownership  interest in the
     Bonds;

                  (b) the delivery to any Agent Member,  beneficial owner of the
         Bonds or other  person,  other than the  Securities  Depository  or its
         nominee as registered owner, of any notice with respect to the Bonds;

                  (c) the payment to any Agent Member,  beneficial  owner of the
         Bonds or other  person,  other than the  Securities  Depository  or its
         nominee  as  registered  owner,  of  any  amount  with  respect  to the
         principal or premium, if any, or interest on the Bonds;

          (d) any consent  given by the  Securities  Depository  or other action
     taken by the Securities Depository as registered owner; or

                  (e) the  selection by the  Securities  Depository or any Agent
         Members of any beneficial  owners to receive  payment in the event of a
         partial redemption of Auction Rate Bonds during

                                                       II-3

         an Auction  Rate Period or Auction  Rate-Inverse  Rate Bonds  during an
         Auction Rate-Inverse Rate Period,  except for the Trustee's obligations
         under Section 5.10.

So long as the certificates for the Bonds of this series or any subseries issued
under the  Indenture are not issued  pursuant to subsection  (4) of this Section
2.03, the Authority,  the Company,  the Trustee,  the Auction Agent,  the Market
Agent,  the Bond  Insurer  and the  Registrar  and  Paying  Agent  may treat the
Securities Depository as, and deem the Securities Depository to be, the absolute
owner  of such  series  or  subseries  of  Bonds  for all  purposes  whatsoever,
including without limitation:

          (a) the payment of principal and premium, if any, and interest on such
     series or subseries of the Bonds;

          (b) giving  notices of  redemption  and other  matters with respect to
     such series or subseries of the Bonds;

          (c) registering  transfers with respect to such series or subseries of
     the Bonds; and

                  (d) obtaining consents under the Indenture.

                  Payment by the Trustee of principal or  redemption  price,  if
any, of and premium,  if any, and interest on such Bonds to or upon the order of
the  Securities  Depository  or its  nominee  during any  period  when it is the
registered  owner of such Bonds  shall be valid and  effective  to  satisfy  and
discharge fully the Authority's obligation with respect to the amounts so paid.

                  3. (a) The Authority may  discontinue  the use of a Securities
         Depository  for the Auction Rate Bonds during an Auction Rate Period or
         the Auction  Rate-Inverse  Rate Bonds  during any Auction  Rate-Inverse
         Rate Period at the time of a Change in the Interest  Rate Mode or on or
         after the Fixed Rate Conversion Date.

                  (b)  Registered  ownership of the Bonds may be  transferred on
         the registration books of the Authority maintained by the Registrar and
         Paying  Agent and the Bonds may be  delivered  in physical  form to the
         following:  (i) any successor Securities  Depository or its nominee; or
         (ii) any person, upon (A) the resignation of the Securities  Depository
         or (B) the  termination  by the Authority of the use of the  Securities
         Depository  from  its  functions  as  depository  as set  forth in this
         section,  or (C) upon  any  Change  in the  Interest  Rate  Mode to any
         Adjustable  Rate  other  than an Auction  Rate  during an Auction  Rate
         Period  or an  Auction  Rate and an  Inverse  Rate  during  an  Auction
         Rate-Inverse Rate Period or on the Fixed Rate Conversion Date.

                  (c) Upon any  Change in the  Interest  Rate Mode to an Auction
         Rate during an Auction  Rate  Period or an Auction  Rate and an Inverse
         Rate during an Auction  Rate-Inverse  Rate Period,  the  Registrar  and
         Paying  Agent shall  register  the Auction Rate Bonds during an Auction
         Rate Period or the Auction  Rate-Inverse  Rate Bonds  during an Auction
         Rate-Inverse

                                                       II-4

         Rate  Period,  as the  case  may  be,  in the  name  of the  Securities
         Depository  or its  nominee  and on the  effective  date of such change
         provide the Company with a list of the Existing  Holders of the Auction
         Rate  Bonds  during  an  Auction  Rate  Period  or  during  an  Auction
         Rate-Inverse Rate Period, as the case may be.

                  4. If at any  time  the  Securities  Depository  notifies  the
Authority  and the  Company  that it is  unwilling  or  unable  to  continue  as
Securities Depository with respect to the Bonds or if at any time the Securities
Depository  shall  no  longer  be  registered  or in  good  standing  under  the
Securities  Exchange  Act  or  other  applicable  statute  or  regulation  and a
successor  Securities  Depository  is not  appointed by the  Authority  with the
consent of the Company,  the Trustee,  the Auction  Agent and the Market  Agent,
within 90 days after the  Authority  and the  Company  receive  notice or become
aware of such  condition,  as the case may be, this  Section  shall no longer be
applicable  and the  Authority  shall execute and the Registrar and Paying Agent
shall  authenticate  and  deliver  certificates  representing  the Bonds of such
series or subseries as provided below. In addition,  the Authority may determine
at any time, at the request of the Market Agent,  that the Bonds shall no longer
be represented  by global bonds and that the  provisions of subsections  (1) and
(2) above shall no longer  apply to such series or  subseries  of Bonds.  In any
such event the Authority  shall execute and the Registrar and Paying Agent shall
authenticate and deliver  certificates  representing the Bonds of such series or
subseries  as  provided  below.  Certificates  for the  Bonds of any  series  or
subseries issued in exchange for a global bond pursuant to this subsection shall
be  registered  in such  names in  authorized  denominations  as the  Securities
Depository,  pursuant to instructions from the Agent Members or otherwise, shall
instruct the Authority  and the  Registrar  and Paying Agent.  The Registrar and
Paying Agent shall  deliver  such  certificates  representing  the Bonds of such
series or subseries  to the persons in whose names such Bonds are so  registered
on the Business Day  immediately  preceding  the first day of an Auction  Period
(with  respect to Auction Rate Bonds during any Auction Rate  Period),  Interest
Period  (with  respect to  Auction  Rate-Inverse  Rate  Bonds  during an Auction
Rate-Inverse  Rate Period),  the effective date of a Change in the Interest Rate
Mode (with  respect to any other  Change in the Interest  Rate Mode),  or on the
Fixed Rate  Conversion  Date (with respect to a conversion to a Fixed Rate),  as
the case may be.

                  5. The  Authority,  the Trustee and the  Registrar  and Paying
Agent are hereby authorized to enter into any arrangements  determined necessary
or desirable with any Securities  Depository in order to effectuate this Section
and both of them  shall  act in  accordance  with  this  Indenture  and any such
agreement.   Without  limiting  the  generality  of  the  foregoing,   any  such
arrangements  may  alter  the  manner  of  effecting  delivery  of Bonds and the
transfer of funds for the payment of Bonds to the Securities Depository.

                  SECTION  2.04.  Limitations  on  Transfer.  (a) So long as the
ownership of the Auction Rate Bonds during any Auction  Rate-Inverse Rate Period
is maintained  in  book-entry  form by the  Securities  Depository,  an Existing
Holder may sell,  transfer or otherwise  dispose of Auction Rate Bonds during an
Auction  Rate-Inverse Rate Period only pursuant to a Bid or Sell Order placed in
an Auction or to or through a  Broker-Dealer  or to a person that has signed and
delivered a Purchaser's  Letter to the Auction Agent,  provided that in the case
of all transfers other than pursuant

                                                       II-5

<PAGE>



to Auctions such Existing Holder,  its Broker-Dealer or its Agent Member advises
the Auction Agent of such transfer.

                  (b) So long as the  ownership of the Auction Rate Bonds during
an Auction  Rate  Period is  maintained  in  book-entry  form by the  Securities
Depository,  an  Existing  Holder may sell,  transfer  or  otherwise  dispose of
Auction Rate Bonds only  pursuant to a Bid or Sell Order placed in an Auction or
to a  Broker-Dealer,  provided,  however,  that  (a)  sale,  transfer  or  other
disposition  of Auction  Rate Bonds from a customer  of a  Broker-Dealer  who is
listed on the records of that Broker-  Dealer as the holder of such Auction Rate
Bonds to that Broker-Dealer or another customer of that Broker-Dealer  shall not
be deemed to be a sale,  transfer  or other  disposition  for  purposes  of this
Section 2.04 if such  Broker-Dealer  remains the Existing  Holder of the Auction
Rate Bonds so sold,  transferred  or  disposed of  immediately  after such sale,
transfer or disposition and (b) in the case of all transfers other than pursuant
to Auctions  such  Broker-Dealer  to whom such transfer is made shall advise the
Auction Agent of such transfer.

                  SECTION 2.05.  Application of Bond  Proceeds.  The proceeds of
sale of the Bonds shall be deposited with the Trustee for deposit in the Project
Fund to be paid out in accordance with Section 8.01.

                  SECTION  2.06.  Delivery  of the  Bonds.  The  Bonds  shall be
executed by the Authority  substantially in the form prescribed by Section 16.01
and in the manner herein set forth and shall be deposited with the Registrar and
Paying  Agent for  authentication,  but  before  the Bonds  shall  initially  be
delivered by the Trustee, there shall be filed with the Trustee the following:

          (a)  an  order  executed  by  an  Authorized   Officer  directing  the
     authentication  and  delivery  of the  Bonds  to or upon  the  order of the
     Securities  Depository  or its nominee,  upon payment to the Trustee of the
     purchase price therein set forth;

                  (b)      two fully executed counterparts of this Indenture;

          (c) two fully executed counterparts of the Participation Agreement;

                  (e)      the fully executed initial Credit Facility;

          (f)  two  fully  executed  counterparts  of the  Bond  Purchase  Trust
     Agreement;

                  (g)      the fully executed Note;

     Bond Insurer and the Trustee,  substantially  to the effect,  and dated as,
     required by Section 8(d)(7)(iii) of the Bond Purchase Agreement;

               (k) opinion of counsel to the Bond Insurer,  substantially to the

         and New York State income tax  purposes  and (iii) that all  conditions
         precedent to the issuance of the Bonds have been met.

                  When the documents mentioned in clauses (a) to (l), inclusive,
of this Section shall have been filed with the Trustee, and when the Bonds shall
have been executed and authenticated as required by this Indenture,  the Trustee
shall deliver the Bonds to the Securities  Depository,  but only upon payment to

                                                 INTEREST ON BONDS

                  SECTION 3.01.  Interest on  Bonds-General.  1. While the Bonds
bear interest at a Commercial Paper Rate, a Daily Rate, a Weekly Rate, a Monthly
Rate or a Semi-annual Rate,  interest accrued on such Bonds shall be computed on
the  basis of a 365 or  366-day  year,  as  applicable,  for the  number of days
actually elapsed.  While the Bonds bear interest at a Term Rate or a Fixed Rate,
interest accrued on such Bonds shall be computed on the basis of a 360-day year,
consisting of twelve (12) thirty (30) day months.  While the Bonds bear interest
at an Auction Rate during an Auction Rate Period, interest accrued on such Bonds
shall be computed on the basis of a 360-day year for the number of days actually
elapsed.  Interest on the  Auction  Rate-Inverse  Rate Bonds  during any Auction
Rate-Inverse Rate Period shall be computed in accordance with Section 3A.07. The
Bonds as initially  issued shall bear interest from the date of issuance thereof
payable on each  Interest  Payment  Date.  The Bonds  issued upon  transfers  or
exchanges  of Bonds shall bear  interest  from the  Interest  Payment  Date next
preceding their date of authentication,  unless the date of authentication is an
Interest  Payment  Date in which case such Bonds shall bear  interest  from such
date,  or  unless  the date of  authentication  is after  the  Record  Date next
preceding the next  succeeding  Interest  Payment Date, in which case such Bonds
shall bear interest from such next succeeding Interest Payment Date.

                  2. The Bonds shall  initially bear interest at an Auction Rate
during an Auction  Rate Period.  From and after any Change in the Interest  Rate
Mode pursuant to Section 4.01,  the Bonds of any series or subseries  shall bear
interest  determined  in  accordance  with  the  provisions  of  this  Indenture
pertaining to the new  Adjustable  Rate.  The Bonds shall bear interest for each
Calculation  Period,  Auction Period or Interest Period,  as the case may be, at
the rate of interest per annum for such  Calculation  Period,  Auction Period or
Interest Period established in accordance with this Indenture.  From and after a
Fixed Rate Conversion  Date, the affected Bonds shall bear interest at the Fixed
Rate until maturity.  Interest shall be payable on each Interest Payment Date by
check mailed to the registered  owner at his or her address as it appears on the
registration  books kept by the  Registrar  and  Paying  Agent  pursuant  to the
Indenture at the close of business on the applicable Record Date; provided, that
(i) while the Securities  Depository is the registered  owner of any Bonds,  all
payments of principal of,  premium,  if any, and interest on such Bonds shall be
paid to the Securities Depository or its nominee by wire transfer, (ii) prior to
and including  the Fixed Rate  Conversion  Date,  interest on the Bonds shall be
payable to any registered owner of at least one million dollars  ($1,000,000) in
aggregate  principal  amount  of Bonds by wire  transfer,  upon  written  notice
received  by the  Registrar  and  Paying  Agent at least  five days prior to the
applicable  Record Date, from such registered owner containing the wire transfer
address  (which  shall  be in the  continental  United  States)  to  which  such
registered owner wishes to have such wire directed and (iii) during a Commercial
Paper Rate Period, interest shall be payable on the Bonds only upon presentation
and surrender  thereof to the  Registrar and Paying Agent upon purchase  thereof
pursuant to Section 5.02 and if such  presentation and surrender is made by 2:00
p.m. (New York City time)

                                                       III-1

<PAGE>



such payment shall be by wire transfer. If and to the extent that there shall be
a default in the payment of the interest due on any Interest  Payment Date, such
interest shall cease to be payable to the person in whose name each Bond of such
series was registered on such applicable Record Date and shall be payable,  when
and if paid to the person in whose name each Bond is  registered at the close of
business on the record date fixed  therefor by the  Trustee,  which shall be the
fifth  Business Day next preceding the date of the proposed  payment.  Except as
provided  above,  payment of the principal of and premium,  if any, on all Bonds
shall be made upon the presentation and surrender of such Bonds at the principal
office of the  Registrar  and  Paying  Agent as the same  shall  become  due and
payable.  The principal of and premium,  if any, and interest on the Bonds shall
be  payable in lawful  money of the United  States of  America.  Each  holder of
Auction Rate Bonds during an Auction  Rate-Inverse Rate Period, by such holder's
purchase  of Auction  Rate  Bonds  during an Auction  Rate-Inverse  Rate  Period
appoints  the  Registrar  and Paying Agent as its agent in  connection  with the
payment  by such  holder of its share,  if any,  of the  amounts  payable to the
Auction  Agent and the  Broker-Dealers  pursuant to  subsections  (c) and (d) of
Section 3A.05.

                  3. Not less than one  Business  Day prior to each  Computation
Date and two Business Days prior to the Fixed Rate Conversion Date, the Indexing
Agent shall  establish  and provide to the  applicable  Market Agent the related
rate index as set forth in the  definition  of such rate index in Section  1.01;
provided  that,  for each  Calculation  Period  during a Daily Rate Period,  the
Indexing  Agent  shall  establish  and  provide  the  related  rate index to the
applicable Market Agent on each  Determination  Date; and provided further that,
for each  Calculation  Period during a Monthly Rate Period,  the Indexing  Agent
shall  establish  and provide the related  rate index to the  applicable  Market
Agent  not  less  than  two  Business  Days  prior  to  each  Computation  Date.
Notwithstanding  the foregoing,  in the event that the Market Agent, in its sole
judgment,  shall determine on a  Determination  Date that any Weekly Rate or any
Commercial Paper Rate Index so established is sufficiently non-representative of
current  market  conditions  that the Bonds may not be remarketed at par if such
rate is set at a rate not greater than 110% of the  applicable  rate index,  the
Market  Agent  may  establish  a new  rate  index  on a  Determination  Date  in
accordance with the procedures and standards set forth in this paragraph and for
purposes of such rate index so established,  all references to Indexing Agent in
this  Indenture  shall be deemed to refer to the Market Agent.  On any date when
any Weekly Rate or any Commercial  Paper Rate Index is established by the Market
Agent  pursuant to this  paragraph,  such rate index  shall have the  respective
meaning set forth in Section 1.01 (except as otherwise provided in the preceding
sentence);  provided that for any Commercial  Paper Rate Index, the Market Agent
shall  select  securities  (whether  or  not  actually  issued)  having  a  term
approximately equal to the applicable  Commercial Paper Rate Period or which are
subject to optional  or  mandatory  tender by the owner  thereof at the end of a
term  approximately  equal to (or as close thereto as is practicably  available)
the applicable  Commercial Paper Rate Period. Upon the occurrence and during the
continuance of a Company  Downgrade Event, the Bond Insurer shall have the right
to consent to any new rate index  proposed by the Market Agent  pursuant to this
paragraph, which consent shall not be unreasonably withheld.

               4. By 12:00 noon (New York City time) on each  Determination Date
          or by 3:00 p.m. (New York City time) on each Auction Date, as the case
          may be, the applicable Market Agent

                                                       III-2

or the Auction Agent, as the case may be, shall determine in accordance with the
terms hereof and make available to the Authority, the Trustee, the Registrar and
Paying Agent, any Support Facility Issuer, the Company, any Broker-Dealer or any
registered  owner  of a Bond  the  interest  rate or  rates  determined  on such
Determination Date or Auction Date.

                  5. If for any reason on any Determination Date (A) any rate of
interest  or a  Calculation  Period  and  related  Commercial  Paper Rate is not
determined by the  applicable  Market  Agent,  (B) no Market Agent is serving as
such  hereunder  or (C)  the  rate  so  determined  is  held  to be  invalid  or
unenforceable  by a final  judgment of a court of  competent  jurisdiction,  (i)
during  any  Daily  Rate  Period,  the  interest  rate for the  next  succeeding
Calculation  Period shall be the last  interest  rate in effect,  or, if a Daily
Rate  is not  determined  by  the  Market  Agent  hereunder  for  five  or  more
consecutive  Business Days on the next and each succeeding  Determination  Date,
the Daily  Rate  shall be a rate per  annum  equal to 80% of the  latest  30-day
dealer taxable  commercial  paper rate published by the Federal  Reserve Bank of
New York on or  immediately  before  such  Determination  Date,  (ii) during any
Weekly Rate Period, the interest rate for the next succeeding Calculation Period
shall  be the  last  interest  rate  in  effect,  or,  if a  Weekly  Rate is not
determined by the Market Agent for two or more consecutive  Calculation Periods,
the  Weekly  Rate  shall be equal to 85% of the  latest  30-day  dealer  taxable
commercial  paper rate  published by the Federal  Reserve Bank of New York on or
before the day next preceding such Determination  Date, (iii) during any Monthly
Rate,  Semi-annual Rate or Term Rate Period, the interest rate per annum for the
next succeeding  Calculation  Period shall be equal to 85% of the rate listed in
the table most  recently  circulated by the United  States  Treasury  Department
known as "Table  [applicable  dates  shown on the most  recent  Table],  Maximum
Interest Rate Payable on United States Treasury  Certificates  of  Indebtedness,
Notes and Bonds-State and Local Government  Series  Subscribed for During Period
[applicable  dates  shown  on the  most  recent  Table]"  or  any  substantially
equivalent  table  circulated by the United States  Treasury  Department for the
maturity most closely  approximating the Calculation Period, and (iv) during any
Commercial Paper Rate Period, the next succeeding  Calculation Period shall be a
Calculation  Period  which shall  consist of the period from and  including  the
prior  Interest  Payment  Date to but  excluding  the first  Business Day of the
following  calendar month and the Commercial Paper Rate shall be equal to 85% of
the interest rate applicable to 90-day United States  Treasury Bills  determined
on the  basis of the  average  per  annum  discount  rate at which  such  90-day
Treasury Bills shall have been sold at the most recent  Treasury  auction within
the 30 days next preceding such Calculation  Period, or if there shall have been
no such auction within the 30 days next preceding such Calculation  Period,  the
Commercial  Paper Rate shall be equal to the rate of interest borne by such Bond
during the next preceding Calculation Period for such Bond. The rate of interest
or  Calculation  Period and related  Commercial  Paper Rate shall be established
pursuant to this subsection 5 until the Market Agent again  determines the rates
of  interest  or  Calculation  Periods  and  related  Commercial  Paper Rates in
accordance  with this  Indenture.  The Trustee shall,  upon the direction of the
Company, select any person otherwise meeting the qualifications of Section 11.14
to  obtain,  calculate  and  prepare  any of the  information  required  by this
subsection 5.

               6. The  determination of any rate of interest by the Market Agent
          in  accordance  with  this  Indenture  or  by  the  Auction  Agent  in
          accordance with the Auction Procedures applicable

                                                       III-3

to Auction  Rate Bonds  during an Auction  Rate Period and Auction  Rate-Inverse
Rate Bonds during an Auction  Rate-Inverse  Rate Period,  as the case may be, or
the establishment of Calculation Periods, Auction Periods or Interest Periods by
the Market Agent as provided in this  Indenture  shall be conclusive and binding
upon the Authority,  the Company,  the Trustee,  the Registrar and Paying Agent,
the Market  Agent,  the Auction  Agent,  any issuer of a Support  Facility,  all
Broker-Dealers and the registered or beneficial owners of the Bonds.  Failure of
the Market Agent, the Trustee, the Registrar and Paying Agent, the Auction Agent
or the Securities  Depository or any Securities  Depository  participant to give
any of the notices described in this Indenture, or any defect therein, shall not
affect  the  interest  rate to be borne by any of the Bonds  nor the  applicable
Calculation Period,  Auction Period or Interest Period nor in any way change the
rights of the registered  owners of the Bonds to tender their Bonds for purchase
or to have them redeemed in accordance with this Indenture.

                  7. No  transfer  or  exchange of Bonds shall be required to be
made by the  Registrar  and  Paying  Agent  after a Record  Date  until the next
succeeding Interest Payment Date.

                  8.  Except as  otherwise  provided in this  subsection  8, the
Trustee shall  calculate and notify the Registrar and Paying Agent of the amount
of interest  due and payable on each  Interest  Payment  Date or date on which a
Bond is subject to  purchase by 10:00 a.m. on the  Business  Day next  preceding
such  Interest  Payment  Date or date set for  purchase,  as the case may be. In
preparing  such  calculation  the  Trustee  may  rely on  calculations  or other
services  provided by the Auction  Agent,  the Market Agent,  the Company or any
person or persons selected by the Trustee in its discretion. During a Commercial
Paper Rate Period, the Market Agent shall notify the Trustee,  the Registrar and
Paying  Agent and the Company of the amount of interest  due and payable on each
Interest  Payment  Date by 10:00 a.m. on the Business  Day next  preceding  such
Interest  Payment Date.  During an Auction Rate Period,  the Auction Agent shall
notify the Trustee at least seven days prior to each  Interest  Payment  Date of
the Auction Rate and the aggregate  amount of interest  payable on such Interest
Payment Date.

                  9.  Anything  herein to the  contrary  notwithstanding,  in no
event  shall the  interest  rate borne by any Bond  exceed the lesser of (i) the
maximum rate  allowable by  applicable  law or (ii) the maximum rate of interest
provided for by any Liquidity Facility in effect at any time.

                  SECTION 3.02.  Commercial Paper Rate. 1. During any Commercial
Paper  Rate  Period,  at or prior to 12:00  noon (New  York  City  time) on each
Determination  Date, the Market Agent shall  establish  Calculation  Periods and
related Commercial Paper Rates. In determining  Calculation  Periods, the Market
Agent shall take the  following  factors into account:  (i) existing  short-term
taxable and tax-exempt  market rates and indices of such short-term  rates, (ii)
the existing  market  supply and demand for  short-term  tax-exempt  securities,
(iii) existing yield curves for short- term and long-term tax-exempt  securities
or  obligations  having a credit rating that is  comparable  to the Bonds,  (iv)
general economic  conditions,  (v) economic and financial factors present in the
securities  industry  that may affect or that may be  relevant  to the Bonds and
(vi) any  information  available to the Market Agent  pertaining  to the Company
regarding any events or anticipated events

                                                       III-4

which could have a direct impact on the  marketability  of or interest  rates on
the Bonds.  The  Market  Agent  shall  select the  Calculation  Periods  and the
applicable  Commercial  Paper Rates that,  together  with all other  Calculation
Periods and related  Commercial  Paper Rates, in the sole judgment of the Market
Agent,  will  result in the lowest  overall  borrowing  cost on the Bonds or are
otherwise  in the best  financial  interests of the Company,  as  determined  in
consultation with the Company. Any Calculation Period established  hereunder may
not extend beyond the Fixed Rate  Conversion  Date, the  expiration  date of the
Support Facility, if any, or the day prior to the maturity date of the Bonds. To
the extent a Liquidity  Facility provides for the payment of accrued interest on
the  Bonds  for a term  less  than  the  established  Calculation  Period,  such
Calculation Period will not extend beyond the coverage provided by the Liquidity
Facility.

                  2. The  Authority,  at the request of the  Company,  may place
such  limitations  upon the  establishment  of Calculation  Periods  pursuant to
subsection  1  hereof  as may be set  forth  in a  written  direction  from  the
Authority,  which direction must be received by the Trustee and the Market Agent
prior to 10:00 a.m.  (New York City time) on the day prior to any  Determination
Date to be effective on such date,  but only if the Trustee  receives an Opinion
of Bond Counsel to the effect that such action is authorized by this  Indenture,
is permitted  under the Act and will not have an adverse effect on the exclusion
of interest on the Bonds from gross income for federal income tax purposes.

                  SECTION  3.03.  Auction  Rate Period - Auction  Rate:  Auction
Period -  General.1.  The Bonds shall be issued  initially as Auction Rate Bonds
during an Auction Rate Period.  During any Auction Rate Period,  the Bonds shall
bear  interest at the Auction Rate  determined as set forth in this Section 3.03
and through  implementation of the Auction Procedures.  The Auction Rate for the
initial  Auction  Period shall be 3.95% per annum.  The initial  Auction  Period
shall  commence from and include the date of original  issuance of the Bonds and
shall expire on and include  January 13, 2000. The initial  Auction Date will be
on January 13, 2000. After the initial Auction Period, each Auction Period shall
be a Standard  Auction  Period.  The Auction Rate for any initial Auction Period
immediately after any Change in the Interest Rate Mode to an Auction Rate for an
Auction Rate  Period,  shall be the rate of interest  per annum  determined  and
certified to the Trustee (with a copy to the Authority, the Registrar and Paying
Agent, the Bond Insurer and the Company) by the Market Agent on a date not later
than the effective  date of such Change in the Interest Rate Mode as the minimum
rate of interest which,  in the opinion of the Market Agent,  would be necessary
as of such date to market Auction Rate Bonds in a secondary  market  transaction
at a price equal to the principal  amount  thereof;  provided that such interest
rate  shall not exceed  the  lesser of 110% of the sum of the  Commercial  Paper
Index and .50% per annum.  For any other Auction Period,  the Auction Rate shall
be the rate of  interest  per annum  that  results  from  implementation  of the
Auction Procedures.  If on any Auction Date the Auction Agent shall fail to take
any action necessary to determine, or take any action which effectively prevents
the determination of, a rate of interest pursuant to the Auction Procedures, the
Auction Rate for the next  succeeding  Auction Period shall equal the No Auction
Rate on and as of such Auction Date. If a Payment  Default shall have  occurred,
the rate of interest for (1) the Auction  Period  commencing  on or  immediately
prior to the date on which such Payment  Default  occurs shall equal the Maximum
Auction Rate, and (2) for each

                                                       III-5

Auction Period  commencing  thereafter to and including the Auction  Period,  if
any, during which, or commencing less than two Business Days after,  all Payment
Defaults are cured, shall equal the Maximum Auction Rate.

                  2. Auction Periods may be established pursuant to Section 3.04
at any time unless a Payment  Default has occurred and has not been cured.  Each
Auction  Period shall be a Standard  Auction  Period unless a different  Auction
Period is  established  pursuant to Section 3.04 and each  Auction  Period which
immediately  succeeds a non-Standard  Auction Period shall be a Standard Auction
Period  unless a different  Auction  Period is  established  pursuant to Section
3.04.

                  SECTION 3.04. Auction Rate Period - Auction Rate Bonds: Change
of Auction Period by Authority.  1. During an Auction Rate Period the Authority,
at the request of the Company,  may change the length of a single Auction Period
or the Standard  Auction Period by means of a written notice  delivered at least
10 days prior to the Auction  Date for such Auction  Period to the Trustee,  the
Market Agent,  the Auction Agent,  the Company and the Securities  Depository in
substantially  the form  attached  hereto as, or  containing  substantially  the
information  contained in,  Exhibit E. If such notice  specifies a change in the
length of the Standard Auction Period, such notice shall be effective only if it
is  accompanied by the written  consent of the Market Agent to such change.  The
length of an Auction  Period or the Standard  Auction  Period may not be changed
pursuant to this Section 3.04 unless  Sufficient  Clearing  Bids existed at both
the Auction  immediately  preceding the date the notice of such change was given
and the Auction immediately preceding such changed Auction Period.

                  2. The change in length of an Auction  Period or the  Standard
Auction  Period shall take effect only if (A) the Trustee,  the Bond Insurer and
the Auction  Agent  receive,  by 11:00 a.m. (New York City time) on the Business
Day  immediately   preceding  the  Auction  Date  for  such  Auction  Period,  a
certificate from the Company, on behalf of the Authority, by telecopy or similar
means in substantially the form attached hereto as, or containing  substantially
the  information  contained in, Exhibit G authorizing  the change in the Auction
Period  or the  Standard  Auction  Period,  which  shall  be  specified  in such
certificate,  and  confirming  that Bond Counsel  expects to be able to give the
Opinion of Bond Counsel on the first day of such Auction  Period  referred to in
(D) below,  (B) the Trustee  shall not have  delivered  to the Auction  Agent by
12:00  noon (New York City time) on the  Auction  Date for such  Auction  Period
notice that a Failure to Deposit has  occurred,  (C)  Sufficient  Clearing  Bids
exist at the Auction on the Auction  Date for such Auction  Period,  and (D) the
Trustee,  the Bond Insurer and the Auction  Agent receive by 9:30 a.m. (New York
City time) on the first day of such Auction  Period,  an opinion of Bond Counsel
to the effect  that the change in the  Auction  Period or the  Standard  Auction
Period is authorized by this Indenture,  is permitted under the Act and will not
have an adverse  effect on the  exclusion  of  interest on such Bonds from gross
income for federal  income tax  purposes.  If the  condition  referred to in (A)
above is not met, the Auction Rate for the next succeeding  Auction Period shall
be determined pursuant to the Auction Procedures and the next succeeding Auction
Period shall be a Standard Auction Period. If any of the conditions  referred to
in (B), (C) or (D) above is not met,  the Auction  Rate for the next  succeeding
Auction Period shall equal the Maximum Auction Rate.

                  SECTION 3.05. Auction Rate Period - Auction Rate Bonds: Change
of Auction Date by Market Agent. During an Auction Rate Period the Market Agent,
with the written  consent of the Company,  may change,  in order to conform with
then-current   market  practice  with  respect  to  similar   securities  or  to
accommodate economic and financial factors that may affect or be relevant to the
day of the week  constituting  an Auction Date,  the Auction Date for all future
Auction  Periods to a different day, so long as the first such Auction Date will
be a Business Day in the calendar week in which the next succeeding Auction Date
is then  scheduled  to occur.  If a change in an Auction Date is  undertaken  in
conjunction  with a change  in an  Auction  Period  and the  conditions  for the
establishment of such change in Auction Period are not met, the Auction Date may
be, and the next succeeding Auction Period may be adjusted to end on, a Business
Day in the calendar  week in which such Auction Date was  scheduled to occur and
such  Auction  Period  was  scheduled  to end to  accommodate  the change in the
Auction  Date.   The  Market  Agent  shall  deliver  a  written  notice  of  its
determination  to change an Auction  Date at least 10 days prior to the  Auction
Date immediately preceding such Auction Date to the Authority,  the Trustee, the
Auction Agent, the Company, the Bond Insurer and the Securities Depository which
shall  state (i) the  determination  of the Market  Agent to change the  Auction
Date,  (ii) the new Auction  Date and (iii) the date on which such  Auction Date
shall be changed.  If as a result of any proposed change in the Auction Date any
Auction  Period  would be less than 28 days in  duration,  such notice  shall be
effective only if it is accompanied by a written statement of the Auction Agent,
the Registrar and Paying Agent, the Trustee, the Market Agent and the Securities
Depository  to the effect  that they are  capable  of  performing  their  duties
hereunder and under the Market Agent Agreement and Auction Agency Agreement with
respect to any such Auction  Period.  Notice of a change in the Auction Date may
be in substantially the form attached hereto as, or containing substantially the
information contained in, Exhibit S.

               SECTION 3.06. Auction Rate Period - Auction Rate Bonds: Orders by
          Existing  Holders and Potential  Holders.  (a) Prior to the Submission
          Deadline on each  Auction  Date during the Auction  Rate  Period,  the
          following orders may be submitted:

               (i) each  Existing  Holder  may  submit to the  Broker-Dealer  by

                           (A) the principal amount of Outstanding  Auction Rate
                  Bonds,  if any,  held  by  such  Existing  Holder  which  such
                  Existing  Holder desires to continue to hold without regard to
                  the Auction Rate for the next succeeding Auction Period;

                           (B) the principal amount of Outstanding  Auction Rate
                  Bonds,  if any,  held  by  such  Existing  Holder  which  such
                  Existing  Holder  offers to sell if the  Auction  Rate for the
                  next succeeding Auction Period shall be less than the rate per
                  annum specified by such Existing Holder and/or

                                                       III-7

                           (C) the principal amount of Outstanding  Auction Rate
                  Bonds,  if any,  held  by  such  Existing  Holder  which  such
                  Existing  Holder offers to sell without  regard to the Auction
                  Rate for the next succeeding Auction Period;

                                    (ii) for the  purpose  of  implementing  the
                           Auctions,  the  Broker-Dealers  may contact Potential
                           Holders by telephone  or  otherwise to determine  the
                           principal  amount of Auction  Rate  Bonds  which each
                           such Potential Holder  irrevocably offers to purchase
                           if the Auction Rate for the next  succeeding  Auction
                           Period shall not be less than the  interest  rate per
                           annum specified by such Potential Holder.

For the purposes  hereof,  the  communication  to a Broker-Dealer of information
referred  to in  clause  (i)(A),  (i)(B)  or  (i)(C)  or  clause  (ii)  above is
hereinafter  referred to as an "Order"  and  collectively  as "Orders"  and each
Existing  Holder  and each  Potential  Holder  placing  an Order is  hereinafter

"Hold  Order"  and  collectively  as  "Hold  Orders";  an Order  containing  the
information  referred to in clause  (i)(B) or clause  (ii) above is  hereinafter
referred to as a "Bid" and  collectively as "Bids";  and an Order containing the
information  referred to in clause (i)(C) above is hereinafter  referred to as a
"Sell  Order"  and   collectively   as  "Sell  Orders".   The  submission  by  a
Broker-Dealer  of an Order to the Auction  Agent  shall  likewise be referred to
herein as an "Order"  and  collectively  as "Orders"  and an Existing  Holder or
Potential  Holder who places an Order with the Auction  Agent or on whose behalf
an Order is placed with the Auction  Agent shall  likewise be referred to herein

                  (b)(i)  Subject to the provisions of Section 3.07, a Bid by an
         Existing Holder shall constitute an irrevocable offer to sell:

                                            (A)   the   principal    amount   of
                                    Outstanding  Auction Rate Bonds specified in
                                    such Bid if the Auction Rate  determined  on
                                    such  Auction  Date  shall be less  than the
                                    interest rate per annum  specified  therein;
                                    or

                           (B)  such  principal  amount  or a  lesser  principal
                  amount of  Outstanding  Auction Rate Bonds to be determined as
                  set forth in subsection (a)(iv) of Section 3.09 if the Auction
                  Rate  determined  on such  Auction  Date shall be equal to the
                  interest rate per annum specified therein; or

                           (C) such principal amount of Outstanding Auction Rate

                  amount or a lesser  principal  amount of  Outstanding  Auction
                  Rate  Bonds  to be  determined  as  set  forth  in  subsection
                  (b)(iii)  of  Section  3.09 if such  specified  rate  shall be

                           3.07,  a  Sell  Order  by an  Existing  Holder  shall
                           constitute an irrevocable offer to sell:

               (A) the  principal  amount  of  Outstanding  Auction  Rate  Bonds
          specified in such Sell Order; or

                  amount  of  Outstanding  Auction  Rate  Bonds as set  forth in
                  subsection  (b)(iii) of Section  3.09 if  Sufficient  Clearing
                  Bids do not exist.

                  (iii)  Subject to the  provisions  of Section 3.07, a Bid by a
         Potential Holder shall constitute an irrevocable offer to purchase:

                           (A) the principal amount of Outstanding  Auction Rate
                  Bonds  specified in such Bid if the Auction Rate determined on
                  such  Auction  Date  shall be higher  than the rate  specified
                  therein; or

                           (B)  such  principal  amount  or a  lesser  principal
                  amount  of  Outstanding  Auction  Rate  Bonds as set  forth in
                  subsection   (a)(v)  of  Section  3.09  if  the  Auction  Rate
                  determined  on  such  Auction  Date  shall  be  equal  to such
                  specified rate.

                  SECTION  3.07.  Auction  Rate  Period -  Auction  Rate  Bonds:
Submission of Orders by  Broker-Dealers  to Auction Agent. (a) During an Auction

prior to the  Submission  Deadline on each  Auction Date during the Auction Rate
Period, all Orders obtained by such Broker-Dealer and shall specify with respect
to each such Order:

               (i) the name of the Bidder placing such Order (which shall be the

               (ii) the  aggregate  principal  amount of Auction Rate Bonds that
          are subject to such Order;

                  (iii)  to the extent that such Bidder is an Existing Holder:

               (A) the principal  amount of Auction Rate Bonds, if any,  subject
          to any Hold Order placed by such Existing Holder;

                           (B) the  principal  amount of Auction Rate Bonds,  if
                  any, subject to any Bid placed by such Existing Holder and the
                  rate specified in such Bid; and

                                                       III-9

               (C) the principal  amount of Auction Rate Bonds, if any,  subject
          to any Sell Order placed by such Existing Holder; and

                                    (iv)  to  the  extent   such   Bidder  is  a
                           Potential  Holder,  the  principal  amount of Auction
                           Rate  Bonds  subject  to any  Bid by  such  Potential
                           Holder and the rate specified in such Bid.

                  (b) If any rate  specified in any Bid contains more than three
figures to the right of the decimal  point,  the Auction  Agent shall round such
rate up to the next highest one thousandth (.001) of 1%.

                  (c)  If an  Order  or  Orders  covering  all or a  portion  of
Outstanding  Auction Rate Bonds held by an Existing  Holder is not  submitted to
the Auction Agent prior to the Submission Deadline, the Auction Agent shall deem
a Hold Order to have been submitted on behalf of such Existing  Holder  covering
the  principal  amount of  Outstanding  Auction Rate Bonds held by such Existing
Holder and not subject to Orders submitted to the Auction Agent.

                  (d) Neither the  Authority,  the Company,  the Trustee nor the
Auction Agent shall be responsible for any failure of a Broker-Dealer  to submit
an Order to the  Auction  Agent on behalf of any  Existing  Holder or  Potential
Holder.

                  (e) If any Existing Holder submits through a Broker-Dealer  to
the Auction  Agent one or more Orders  covering in the  aggregate  more than the
principal amount of Auction Rate Bonds held by such Existing Holder, such Orders
shall be considered valid as follows and in the following order of priority:

                           (i) all Hold Orders shall be  considered  valid,  but
         only up to and  including  the  principal  amount of Auction Rate Bonds
         held by such Existing Holder, and, if the aggregate principal amount of
         Auction Rate Bonds  subject to such Hold Orders  exceeds the  aggregate
         principal  amount  of  Outstanding  Auction  Rate  Bonds  held  by such
         Existing Holder,  the aggregate  principal amount of Auction Rate Bonds
         subject to each such Hold Order  shall be reduced pro rata to cover the
         aggregate  principal  amount of Outstanding  Auction Rate Bonds held by
         such Existing Holder;

                           (ii) (A) any Bid shall be considered  valid up to and
                  including  the excess of the principal  amount of  Outstanding
                  Auction  Rate  Bonds  held by such  Existing  Holder  over the
                  aggregate  principal  amount of Auction Rate Bonds  subject to
                  any Hold Orders referred to in paragraph (i) above;

                                    (B)  subject to clause  (A)  above,  if more
                           than  one Bid  with the  same  rate is  submitted  on
                           behalf  of such  Existing  Holder  and the  aggregate
                           principal  amount of  Outstanding  Auction Rate Bonds
                           subject  to such Bids is  greater  than such  excess,
                           such Bids shall be considered valid up to and

                                                      III-10

                           including  the  amount  of  such  excess,   and,  the
                           principal  amount of Auction  Rate  Bonds  subject to
                           each Bid with the same rate shall be reduced pro rata
                           to cover the  principal  amount of Auction Rate Bonds
                           equal to such excess;

                                    (C) subject to clauses (A) and (B) above, if
                           more than one Bid with  different  rates is submitted
                           on behalf of such Existing Holder, such Bids shall be
                           considered  valid  in the  ascending  order  of their
                           respective rates until the highest rate is reached at
                           which such excess  exists and then at such rate up to
                           and including the amount of such excess; and

                                    (D)  in  any  such  event,   the   aggregate
                           principal  amount of Outstanding  Auction Rate Bonds,
                           if any,  subject  to any  portion  of Bids not  valid
                           under  this  paragraph  (ii)  shall be treated as the
                           subject  of a Bid by a  Potential  Holder at the rate
                           therein specified; and

                                                     (iii) all Sell Orders shall
                                            be   considered   valid  up  to  and
                                            including    the   excess   of   the
                                            principal   amount  of   Outstanding
                                            Auction  Rate  Bonds  held  by  such
                                            Existing  Holder over the  aggregate
                                            principal  amount  of  Auction  Rate
                                            Bonds  subject to valid Hold  Orders
                                            referred to in paragraph (i) of this
                                            subsection   (e)  and   valid   Bids
                                            referred  to in  paragraph  (ii)  of
                                            this subsection (e).

                  (f) If more than one Bid for Auction  Rate Bonds is  submitted
on behalf of any Potential  Holder,  each Bid submitted  shall be a separate Bid
for Auction Rate Bonds with the rate and principal amount therein specified.

                  (g) Any Bid or Sell  Order  submitted  by an  Existing  Holder
covering  an  aggregate  principal  amount of  Auction  Rate  Bonds not equal to
$25,000 or an integral  multiple thereof shall be rejected and shall be deemed a
Hold Order.  Any Bid  submitted  by a  Potential  Holder  covering an  aggregate
principal  amount of Auction  Rate  Bonds not equal to  $25,000  or an  integral
multiple thereof shall be rejected.

                  (h) Any Bid  submitted  by an  Existing  Holder or a Potential
Holder  specifying a rate lower than the Minimum  Auction Rate, if any, shall be
treated as a Bid specifying the Minimum Auction Rate.

                  SECTION  3.08.  Auction  Rate  Period -  Auction  Rate  Bonds:
Determination  of Sufficient  Clearing Bids,  Winning Bid Rate and Auction Rate.
(a) During an Auction  Rate Period not earlier than the  Submission  Deadline on
each  Auction  Date  during the Auction  Rate  Period,  the Auction  Agent shall
assemble  all valid Orders  submitted  or deemed  submitted to it by the Broker-
Dealers  (each such Order as  submitted or deemed  submitted by a  Broker-Dealer
being hereinafter

referred to as a "Submitted  Hold Order," a "Submitted Bid" or a "Submitted Sell
Order," as the case may be, or as a "Submitted Order") and shall determine:

                           (i) the  excess  of the  total  principal  amount  of
                  Outstanding  Auction Rate Bonds over the  aggregate  principal
                  amount of Outstanding  Auction Rate Bonds subject to Submitted
                  Hold Orders (such excess being hereinafter  referred to as the
                  "Available Auction Rate Bonds"); and

                           (ii) from the Submitted  Orders whether the aggregate
                  principal amount of Outstanding  Auction Rate Bonds subject to
                  Submitted  Bids by Potential  Holders  specifying  one or more
                  rates equal to or lower than the Maximum  Auction Rate exceeds
                  or is equal to the sum of:

                                    (A)  the  aggregate   principal   amount  of
                           Outstanding  Auction Rate Bonds  subject to Submitted
                           Bids by Existing Holders specifying one or more rates
                           higher than the Maximum Auction Rate; and

               (B) the aggregate  principal  amount of Outstanding  Auction Rate
          Bonds subject to Submitted Sell Orders

                  (in the event of such  excess  or such  equality  (other  than
                  because the sum of the principal amounts of Auction Rate Bonds
                  in  clauses  (A) and (B)  above  is  zero  because  all of the
                  Outstanding  Auction Rate Bonds are subject to Submitted  Hold
                  Orders),   such  Submitted  Bids  by  Potential   Holders  are
                  hereinafter  referred to collectively as "Sufficient  Clearing
                  Bids"); and

                                                     (iii)     if     Sufficient
                                            Clearing Bids exist, the lowest rate
                                            specified in the Submitted Bids (the
                                            "Winning Bid Rate") which if:

                                    (A)(I)  each  Submitted  Bid  from  Existing
                           Holders  specifying  such  lowest  rate  and (II) all
                           other Submitted Bids from Existing Holders specifying
                           lower  rates  were  rejected,   thus  entitling  such
                           Existing  Holders to continue  to hold the  principal
                           amount of Auction  Rate Bonds that are the subject of
                           such Submitted Bids; and

                                    (B)(I)  each  Submitted  Bid from  Potential
                           Holders  specifying  such  lowest  rate  and (II) all
                           other   Submitted   Bids   from   Potential   Holders
                           specifying lower rates were accepted,

                  would result in such Existing Holders  described in clause (A)
                  above  continuing  to hold an  aggregate  principal  amount of
                  Outstanding  Auction  Rate  Bonds  which,  when  added  to the
                  aggregate  principal amount of Outstanding  Auction Rate Bonds
                  to be

                  purchased by such  Potential  Holders  described in clause (B)
                  above,  would equal not less than the  Available  Auction Rate
                  Bonds.

                  (b)   Promptly   after   the   Auction   Agent  has  made  the
determinations  pursuant to  subsection  (a) of this Section  3.08,  the Auction
Agent, by telecopy confirmed in writing,  shall advise the Company,  the Trustee
and the  Broker-Dealers  of the  Auction  Rate for the next  succeeding  Auction
Period as follows:

                           (i) if Sufficient  Clearing  Bids exist,  the Auction
                  Rate for the next succeeding  Auction Period therefor shall be
                  equal to the Winning Bid Rate so determined;

                           (ii) if Sufficient  Clearing Bids do not exist (other
                  than because all of the Outstanding Auction Rate Bonds are the
                  subject of Submitted  Hold  Orders),  the Auction Rate for the
                  next succeeding  Auction Period therefor shall be equal to the
                  Maximum Auction Rate; and

                           (iii) if all of the Auction Rate Bonds are subject to
                  Submitted   Hold  Orders,   the  Auction  Rate  for  the  next
                  succeeding  Auction  Period  therefor  shall  be  equal to the
                  Minimum Auction Rate.

                  SECTION  3.09.  Auction  Rate  Period -  Auction  Rate  Bonds:
Acceptance  and  Rejection  of  Submitted  Bids and  Submitted  Sell  Orders and
Allocation of Auction Rate Bonds. During an Auction Rate Period Existing Holders
shall  continue  to hold the  principal  amounts of Auction  Rate Bonds that are
subject to Submitted Hold Orders, and, based on the determinations made pursuant
to subsection  (a) of this Section 3.09,  the Submitted  Bids and Submitted Sell
Orders shall be accepted or rejected and the Auction Agent shall take such other
actions as are set forth below:

                  (a) If  Sufficient  Clearing Bids exist,  all  Submitted  Sell
         Orders shall be accepted and,  subject to the  provisions of paragraphs
         (e) and (f) of this Section 3.09,  Submitted  Bids shall be accepted or
         rejected as follows in the following order of priority:

                           (i) Existing  Holders'  Submitted Bids specifying any
                  rate  that is  higher  than  the  Winning  Bid  Rate  shall be
                  accepted, thus requiring each such Existing Holder to sell the
                  aggregate  principal  amount of Auction Rate Bonds  subject to
                  such Submitted Bids;

                           (ii) Existing Holders'  Submitted Bids specifying any
                  rate  that is  lower  than  the  Winning  Bid  Rate  shall  be
                  rejected, thus entitling each such Existing Holder to continue
                  to hold the aggregate  principal  amount of Auction Rate Bonds
                  subject to such Submitted Bids;

                                                      III-13

<PAGE>



                           (iii)  Potential  Holders'  Submitted Bids specifying
                  any rate  that is lower  than the  Winning  Bid Rate  shall be
                  accepted,   thus  requiring  each  such  Potential  Holder  to
                  purchase the aggregate  principal amount of Auction Rate Bonds
                  subject to such Submitted Bids;

                           (iv) each Existing Holder's  Submitted Bid specifying
                  a rate  that  is  equal  to the  Winning  Bid  Rate  shall  be
                  rejected,  thus entitling such Existing  Holder to continue to
                  hold the  aggregate  principal  amount of  Auction  Rate Bonds
                  subject to such Submitted Bid, unless the aggregate  principal
                  amount of  Outstanding  Auction Rate Bonds subject to all such
                  Submitted  Bids shall be greater than the principal  amount of
                  Auction Rate Bonds (the "remaining principal amount") equal to
                  the excess of Available  Auction Rate Bonds over the aggregate
                  principal   amount  of  the  Auction  Rate  Bonds  subject  to
                  Submitted Bids described in paragraphs  (ii) and (iii) of this
                  subsection  (a),  in which  event such  Submitted  Bid of such
                  Existing  Holder shall be rejected in part,  and such Existing
                  Holder  shall be entitled  to  continue to hold the  principal
                  amount of Auction Rate Bonds  subject to such  Submitted  Bid,
                  but only in an amount equal to the principal amount of Auction
                  Rate Bonds  obtained by  multiplying  the remaining  principal
                  amount by a  fraction,  the  numerator  of which  shall be the
                  principal  amount of  Outstanding  Auction  Rate Bonds held by
                  such  Existing  Holder  subject to such  Submitted Bid and the
                  denominator of which shall be the sum of the principal amounts
                  of Auction Rate Bonds subject to such  Submitted  Bids made by
                  all such Existing  Holders that  specified a rate equal to the
                  Winning Bid Rate;

                           (v) each Potential  Holder's Submitted Bid specifying
                  a rate that is equal to the Winning Bid Rate shall be accepted
                  but only in an amount equal to the principal amount of Auction
                  Rate Bonds obtained by multiplying the excess of the Available
                  Auction  Rate Bonds  over the  aggregate  principal  amount of
                  Auction  Rate Bonds  subject to  Submitted  Bids  described in
                  paragraphs  (ii),  (iii) and (iv) of this  subsection (a) by a
                  fraction  the  numerator  of  which  shall  be  the  aggregate
                  principal  amount  of  Auction  Rate  Bonds  subject  to  such
                  Submitted Bid of such Potential  Holder and the denominator of
                  which shall be the sum of the principal  amount of Outstanding
                  Auction Rate Bonds subject to Submitted  Bids made by all such
                  Potential  Holders that  specified a rate equal to the Winning
                  Bid Rate,  and the remainder of such  Submitted  Bids shall be
                  rejected; and

                           (vi) each Potential Holder's Submitted Bid specifying
                  a rate  that is  higher  than the  Winning  Bid Rate  shall be
                  rejected.

                  (b) If  Sufficient  Clearing  Bids do not  exist  (other  than
         because  all of the  Outstanding  Auction  Rate  Bonds are  subject  to
         Submitted Hold Orders),  subject to the provisions of subsection (e) of
         this Section  3.09,  Submitted  Orders shall be accepted or rejected as
         follows in the following order of priority:

                                    (i)   Existing   Holders'   Submitted   Bids
                           specifying  any rate  that is equal to or lower  than
                           the  Maximum  Auction  Rate shall be  rejected,  thus
                           entitling  each such  Existing  Holder to continue to
                           hold the aggregate  principal  amount of Auction Rate
                           Bonds subject to such Submitted Bids;

                           (ii) Potential Holders' Submitted Bids specifying any
                  rate that is equal to or lower than the Maximum  Auction  Rate
                  shall be accepted,  thus requiring each such Potential  Holder
                  to purchase  the  aggregate  principal  amount of Auction Rate
                  Bonds subject to such Submitted Bids;

                           (iii) each Existing Holder's Submitted Bid specifying
                  any rate that is higher than the Maximum  Auction Rate and the
                  Submitted  Sell  Order  of  each  Existing   Holder  shall  be
                  accepted,  thus entitling each Existing  Holder that submitted
                  any such  Submitted  Bid or  Submitted  Sell Order to sell the
                  Auction Rate Bonds subject to such  Submitted Bid or Submitted
                  Sell Order,  but in both cases only in an amount  equal to the
                  aggregate  principal  amount of Auction Rate Bonds obtained by
                  multiplying  the  aggregate  principal  amount of Auction Rate
                  Bonds subject to Submitted Bids described in paragraph (ii) of
                  this  subsection  (b) by a fraction,  the  numerator  of which
                  shall be the aggregate principal amount of Outstanding Auction
                  Rate  Bonds  held  by such  Existing  Holder  subject  to such
                  Submitted Bid or Submitted  Sell Order and the  denominator of
                  which shall be the aggregate  principal  amount of Outstanding
                  Auction  Rate  Bonds  subject to all such  Submitted  Bids and
                  Submitted Sell Orders; and

                           (iv) each Potential Holder's Submitted Bid specifying
                  a rate that is higher than the Maximum  Auction  Rate shall be
                  rejected.

               (c)  If  all  Outstanding  Auction  Rate  Bonds  are  subject  to
          Submitted Hold Orders, all Submitted Bids shall be rejected.

                  (d) If (i) the  Auction  Agent  shall  fail to take any action
         necessary to determine,  or take any action which effectively  prevents
         the  determination  of,  an  interest  rate  pursuant  to  the  Auction
         Procedures or (ii) the  conditions set forth in subsection 2 of Section
         3.04 to  effect  a  change  in the  Auction  Period  are not  met,  all
         Submitted  Bids and  Submitted  Sell Orders  shall be rejected  and the
         existence of Sufficient Clearing Bids shall be of no effect.

                  (e) If, as a result of the procedures  described in subsection
         (a) or (b) of this Section 3.09, any Existing  Holder would be entitled
         or  required  to sell,  or any  Potential  Holder  would be required to
         purchase, a principal amount of Auction Rate Bonds that is not equal to
         $25,000 or an integral  multiple  thereof,  the Auction Agent shall, in
         such manner as, in its sole discretion, it shall determine, round up or
         down the principal amount of such Auction Rate Bonds to be purchased or
         sold by any Existing Holder or Potential Holder so

                                                      III-15

         that the principal  amount purchased or sold by each Existing Holder or
         Potential  Holder  shall be equal to  $25,000 or an  integral  multiple
         thereof.

                  (f) If, as a result of the procedures  described in subsection
         (a) of this Section  3.09,  any  Potential  Holder would be entitled or
         required to purchase less than $25,000 in aggregate principal amount of
         Auction Rate Bonds,  the Auction Agent shall, in such manner as, in its
         sole discretion,  it shall  determine,  allocate Auction Rate Bonds for
         purchase  among  Potential  Holders so that only  Auction Rate Bonds in
         principal  amounts of  $25,000  or an  integral  multiple  thereof  are
         purchased by any Potential Holder,  even if such allocation  results in
         one or more of such  Potential  Holders not purchasing any Auction Rate
         Bonds.

                  (g) Based on the results of each  Auction,  the Auction  Agent
         shall determine the aggregate  principal  amounts of Auction Rate Bonds
         to be purchased  and the  aggregate  principal  amounts of Auction Rate
         Bonds to be sold by Potential  Holders and Existing  Holders and,  with
         respect to each  Potential  Holder and Existing  Holder,  to the extent
         that such aggregate  principal  amount of Auction Rate Bonds to be sold
         differs from such aggregate  principal  amount of Auction Rate Bonds to
         be purchased,  determine to which other Potential Holder(s) or Existing
         Holder(s) they shall deliver,  or from which other Potential  Holder(s)
         or Existing  Holder(s) they shall receive,  as the case may be, Auction
         Rate Bonds.

                  (h) The  purchase  price of each Auction Rate Bond sold in any
         Auction  shall be  equal to  $25,000,  except  that if the then  ending
         Auction  Period is a daily Auction  Period,  the purchase price of each
         Auction Rate Bond shall be $25,000,  plus  accrued and unpaid  interest
         thereon,  unless the purchase date is also an Interest Payment Date, in
         which  case the  purchase  price of such  Auction  Rate  Bond  shall be
         $25,000.

                  (i)  None  of the  Authority,  the  Company  or any  Affiliate
         thereof may submit an Order in any  Auction  except as set forth in the
         next sentence.  Any  Broker-Dealer  that is an Affiliate of the Company
         may not submit  Bids to purchase  Auction  Rate Bonds in an Auction for
         its own account,  provided that  affiliated  Broker-Dealers  may submit
         Hold Orders and Sell Orders in Auctions  with  respect to Auction  Rate
         Bonds otherwise acquired for its own account.

                  SECTION  3.10.  Auction  Rate  Period -  Auction  Rate  Bonds:
Adjustment in Percentage.  1. During an Auction Rate Period the Market Agent may
adjust the  percentage  used in  determining  the Minimum  Auction  Rate and the
Applicable  Percentages  used in  determining  the No  Auction  Rate if any such
adjustment  is necessary,  in the judgment of the Market  Agent,  to reflect any
Change of Preference Law or to conform to market  practice such that the Minimum
Auction Rate and No Auction Rate shall have  substantially  equal market  values
before and after such Change of Preference Law or change in market practice.  In
making any such adjustment as a result of a Change of Preference Law, the Market
Agent shall take the following  factors,  as in existence  both before and after
such  Change of  Preference  Law,  into  account:  (i)  short-term  taxable  and
tax-exempt market

                                                      III-16

<PAGE>



rates and indices of such  short-term  rates,  (ii) the market supply and demand
for  short-term  tax- exempt  securities,  (iii) yield curves for short-term and
long-term  tax-exempt  securities or obligations  having a credit rating that is
comparable to the Bonds,  (iv) general economic  conditions and (v) economic and
financial factors present in the securities industry that may affect or that may
be relevant  to the Bonds.  In making any such  adjustment  to conform to market
practice,  the Market  Agent shall take into  account such factors as the Market
Agent  deems  relevant,  including  the  terms of  auction  rate  bonds of other
issuers.  Upon the occurrence and continuance of a Company  Downgrade Event, the
Bond  Insurer  shall have the right to  consent to any change to the  percentage
used in  determining  the Minimum  Auction Rate and the  Applicable  Percentages
using  in  determining  the  No  Auction  Rate,   which  consent  shall  not  be
unreasonably withheld.

                  2. The Market Agent shall  communicate  its  determination  to
adjust the  percentage  used in  determining  the Minimum  Auction  Rate and the
Applicable  Percentages  used in  determining  the No Auction  Rate  pursuant to
subsection 1 hereof by means of a written notice delivered at least 5 days prior
to the Auction  Date on which the Market  Agent  desires to effect the change to
the Authority,  the Trustee,  the Auction Agent and the Company in substantially
the form  attached  hereto  as,  or  containing  substantially  the  information
contained  in,  Exhibit  F.  Such  notice  shall  be  effective  only  if  it is
accompanied  by the form of opinion  that Bond  Counsel  has  advised the Market
Agent that it expects to be able to give on such Auction Date to the effect that
such adjustment is authorized by this Indenture,  is permitted under the Act and
will not have an adverse effect on the exclusion of interest on the Auction Rate
Bonds from gross income for federal  income tax  purposes.  The Auction Agent is
required to mail notice thereof to the Existing Holders within two Business Days
of receipt thereof.

                  3. An adjustment in the  percentage  used in  determining  the
Minimum Auction Rate and the Applicable  Percentages  used in determining the No
Auction Rate shall take effect on an Auction  Date only if (A) the Trustee,  the
Bond Insurer and the Auction Agent  receive,  by 11:00 a.m. (New York City time)
on the Business Day immediately  preceding such Auction Date, a certificate from
the  Market  Agent by  telecopy  or similar  means,  in  substantially  the form
attached hereto as, or containing  substantially  the information  contained in,
Exhibit H, (i)  authorizing the adjustment of the percentage used in determining
the Minimum Auction Rate and the Applicable  Percentages used in determining the
No  Auction  Rate  which  shall be  specified  in such  authorization,  and (ii)
confirming  that Bond  Counsel  expects  to be able to give an  opinion  on such
Auction  Date to the  effect  that  the  adjustment  in the  percentage  used in
determining  the Minimum  Auction Rate and the  Applicable  Percentages  used in
determining  the No Auction Rate is authorized by this  Indenture,  is permitted
under the Act and will not have an adverse  effect on the  exclusion of interest
on the Auction Rate Bonds from gross income for federal income tax purposes, and
(B) the  Trustee,  the Bond Insurer and the Auction  Agent  receive by 9:30 a.m.
(New York City time) on such  Auction  Date,  an opinion of Bond  Counsel to the
effect that the  adjustment in the percentage  used in  determining  the Minimum
Auction Rate and the Applicable  Percentages  used in determining the No Auction
Rate is authorized by this  Indenture,  is permitted  under the Act and will not
have an adverse  effect on the  exclusion  of interest on the Auction Rate Bonds
from gross income for federal income tax purposes.  If the condition referred to
in (A) above is not met, the existing percentage used in

                                                      III-17

<PAGE>



determining  the Minimum  Auction Rate and the  Applicable  Percentages  used in
determining  the No Auction Rate shall remain in effect and the Auction Rate for
the next succeeding  Auction Period shall be determined  pursuant to the Auction
Procedures.  If the condition  referred to in (B) above is not met, the existing
percentage  used in  determining  the Minimum  Auction  Rate and the  Applicable
Percentages  used in determining  the No Auction Rate shall remain in effect and
the Auction Rate for the next succeeding  Auction Period shall equal the Maximum
Auction Rate.

(with a copy to the  Authority,  the Registrar and Paying Agent and the Company)
on a date not later than the  effective  date of the Change in the Interest Rate
Mode as the minimum rate of interest  which, in the opinion of the Market Agent,
would be  necessary as of such date to market the Auction Rate Bonds during such
Initial  Interest Period in a secondary  market  transaction at a price equal to
the principal amount thereof;  provided, however that the Auction Rate shall not
exceed the excess of the  Maximum  Auction  Rate-Inverse  Rate over the  Service
Charge Rate.  Commencing on and including each Initial Interest Payment Date the
rate of interest on the Auction Rate Bonds during any Auction  Rate-Inverse Rate
Period for each subsequent interest period therefor  (hereinafter referred to as
a  "Subsequent  Interest  Period";  and  the  Initial  Interest  Period  or  any
Subsequent  Interest  Period  being  hereinafter  referred  to as  an  "Interest
Period"),  which  Subsequent  Interest  Period  shall  commence  on the  Regular
Interest  Payment Date for the  preceding  Interest  Period and shall end on but
exclude the next succeeding  Interest Payment Date, shall be equal to the sum of
the rate of interest per annum that results from  implementation  of the Auction
Procedures (the "Auction Rate") and the Service Charge Rate; provided that

                  (i)(A) if a notice of an adjustment in the percentage  used to
         determine  the  Minimum  Rate  and the  Applicable  Percentage  used in
         determining  the Maximum Rate shall have been given by the Market Agent
         in accordance with Section 3A.09.3 and, because of a failure to satisfy
         the  condition  set  forth  in  clause  (B)  of  Section  3A.09.3  such
         adjustment shall not have taken effect, an Auction shall not be held on
         the Auction Date immediately  preceding the next succeeding  Subsequent
         Interest Period and the rate of interest for such  Subsequent  Interest
         Period shall equal the sum of the Maximum Rate on such Auction Date and
         the Service Charge Rate on such Auction Date;

                  (ii)  [reserved];

                  (iii) if at the close of business  on the Regular  Record Date
         immediately  preceding any Subsequent  Interest Period all Auction Rate
         Bonds are Linked with Inverse Rate Bonds,  an Auction shall not be held
         with  respect  to such  Subsequent  Interest  Period  and  the  rate of
         interest for such  Subsequent  Interest  Period shall equal the Minimum
         Rate on the Business Day  immediately  preceding  the first day of such
         Subsequent Interest Period;

                  (iv)(A)  if  any  of  the  conditions  set  forth  in  Section
         4.01.3(A)(i)  or (ii) with respect to any Change in the  Interest  Rate
         Mode  from  an  Auction  Rate-Inverse  Rate  Period,  or if  any of the
         conditions set forth in Section  4.02.3(A) with respect to a conversion
         to a  Fixed  Rate is not  met,  the  Auction  Rate  for the  Subsequent
         Interest  Period  shall be  determined  pursuant to Auction  Procedures
         applicable to the Auction  Rate-Inverse  Rate Bonds,  and (B) if any of
         the  conditions  set forth in Section  4.01.3(A)(iii),  (C) or (D) with
         respect  to any  Change  in the  Interest  Rate  Mode  from an  Auction
         Rate-Inverse  Rate  Period,  or if any of the  conditions  set forth in
         Section  4.02.3(B) with respect to a conversion to a Fixed Rate from an
         Auction  Rate-  Inverse Rate Period is not met, an Auction shall not be
         held with  respect to the  Subsequent  Interest  Period and the Auction
         Rate for such  Subsequent  Interest  Period  shall equal the sum of the
         Maximum Rate and the Service Charge Rate on such Auction Date; and

                  (v) if on any  Auction  Date,  an  Auction is not held for any
         other reason,  the rate of interest for the next succeeding  Subsequent
         Interest Period shall equal the sum of the Maximum Rate on such Auction
         Date and the Service Charge Rate on such Auction Date.

Notwithstanding the foregoing, if:

                  (A) the  ownership  of the  Auction  Rate  Bonds is no  longer
         maintained in book-entry form by the Securities Depository, the rate of
         interest  for any  Subsequent  Interest  Period  commencing  after  the
         delivery of  certificates  representing  Auction Rate Bonds pursuant to
         Section  2.03 hereof  shall equal the Maximum  Rate on the Business Day
         immediately preceding the first day of such Subsequent Interest Period;
         or

                  (B) a  Payment  Default  shall  have  occurred,  the  rate  of
         interest  for (1)  the  Subsequent  Interest  Period  commencing  on or
         immediately  prior to the date on which  such  Payment  Default  occurs
         shall  equal  the sum of the  Overdue  Rate as of the first day of such
         Subsequent   Interest  Period  and  the  Service  Charge  Rate  on  the
         immediately  preceding  Auction  Date,  and  (2)  for  each  Subsequent
         Interest Period  commencing  thereafter to and including the Subsequent
         Interest  Period,  if any,  during which,  or commencing  less than two
         Business  Days  after,  such  Payment  Default is cured shall equal the
         Overdue Rate on the first day of each such Subsequent Interest Period

(the rate per annum at which  interest is payable on the Auction  Rate Bonds for
any Interest Period being  hereinafter  referred to as the  "Applicable  Auction
Rate").

The rate of  interest  on the Inverse  Rate Bonds  during the  Initial  Interest
Period and for each Subsequent Interest Period, shall be equal to the excess, if
any, taken (without rounding) to one thousandth (.001) of 1%, of:

                  (i)  two times the Linked Rate over

               (ii) the product of the Applicable Auction Rate for such Interest
          Period and 365/360,

provided that in no event shall such rate exceed the maximum rate on the date of
determination  permitted  by New York law, as the same may be modified by United
States  law of  general  application  (the rate per annum at which  interest  is
payable on the Inverse  Rate Bonds for any  Interest  Period  being  hereinafter
referred to as the "Applicable Inverse Rate").

                           (C) Subject to the  provisions of  subsection  (b) of
                  this  Section  3A.03,  a  Bid  by  a  Potential  Holder  shall
                  constitute an irrevocable offer to purchase:

                                    (I)  the  principal  amount  of  Outstanding
                           Auction  Rate  Bonds  specified  in  such  Bid if the
                           Auction Rate  determined  as provided in this Section
                           3A.03  shall  be  higher  than  the  rate   specified
                           therein; or

                                    (II)  such  principal  amount  or  a  lesser
                           principal amount of Outstanding Auction Rate Bonds as
                           set  forth  in  clause  (E)  of   paragraph   (i)  of
                           subsection  (d) of this Section  3A.03 if the Auction
                           Rate  determined  as provided in this  Section  3A.03
                           shall be equal to the rate specified therein.

          Agent prior to the Submission Deadline on each Auction Date all Orders
          obtained by such  Broker-Dealer and shall specify with respect to each

                           (A) the name of the Bidder placing such Order;

               (B) the aggregate principal amount of Auction Rate Bonds that are
          the subject
                  of such Order;

                                    (I) the  principal  amount of  Auction  Rate
                           Bonds,  if any,  subject to any Hold Order  placed by
                           such Existing Holder;

                                    (II) the  principal  amount of Auction  Rate
                           Bonds,  if any,  subject  to any Bid  placed  by such
                           Existing  Holder and the rate  specified in such Bid;
                           and

                                    (III) the  principal  amount of Auction Rate
                           Bonds,  if any,  subject to any Sell Order  placed by
                           such Existing Holder; and

                           (D) to the extent such Bidder is a Potential  Holder,
                  the rate specified in such Potential Holder's Bid.

                  (ii) If any rate specified in any Bid contains more than three
         figures to the right of the  decimal  point,  the  Auction  Agent shall
         round such rate up to the next highest one thousandth (.001) of 1%.

                  (iii) If an Order or Orders covering all  Outstanding  Auction
         Rate Bonds held by any Existing  Holder is not submitted to the Auction
         Agent prior to the Submission Deadline,  the Auction Agent shall deem a
         Hold Order to have been  submitted  on behalf of such  Existing  Holder
         covering the principal amount of Outstanding Auction Rate Bonds held by
         such  Existing  Holder  and not  subject to an Order  submitted  to the
         Auction Agent.

                  (iv) None of the  Authority,  the Company,  the Trustee or the
         Auction Agent shall be responsible  for any failure of a  Broker-Dealer
         to submit  an Order to the  Auction  Agent on  behalf  of any  Existing
         Holder or Potential Holder.

                  (v) If any Existing Holder submits through a Broker-Dealer  to
         the Auction  Agent one or more Orders  covering in the  aggregate  more
         than the  principal  amount of  Outstanding  Auction Rate Bonds held by
         such Existing Holder,  such Orders shall be considered valid as follows
         and in the following order of priority:

                                                     (A) all Hold  Orders  shall
                                            be considered  valid, but only up to
                                            and  including in the  aggregate the
                                            principal  amount  of  Auction  Rate
                                            Bonds held by such Existing  Holder,
                                            and  if  the   aggregate   principal
                                            amount of Auction Rate Bonds subject
                                            to  such  Hold  Orders  exceeds  the
                                            aggregate    principal   amount   of
                                            Outstanding  Auction Rate Bonds held
                                            by   such   Existing   Holder,   the
                                            aggregate    principal   amount   of
                                            Auction  Rate Bonds  subject to each
                                            such Hold Order shall be reduced pro
                                            rata   to   cover   the    aggregate
                                            principal   amount  of   Outstanding
                                            Auction  Rate  Bonds  held  by  such
                                            Existing Holder;

                           (B)(I)  any Bid shall be  considered  valid up to and
                  including  the excess of the principal  amount of  Outstanding
                  Auction  Rate  Bonds  held by such  Existing  Holder  over the
                  aggregate  principal  amount of Auction Rate Bonds  subject to
                  any Hold Orders  referred  to in clause (A) of this  paragraph
                  (v);

                                    (II) subject to subclause (I) of this clause
                           (B),  if more  than one Bid  with  the  same  rate is
                           submitted on behalf of such  Existing  Holder and the
                           aggregate  principal  amount of  Outstanding  Auction
                           Rate Bonds  subject to such Bids is greater than such
                           excess, such Bids shall be considered valid up to and
                           including   the  amount  of  such  excess,   and  the
                           principal  amount of Auction  Rate  Bonds  subject to
                           each Bid with the same rate shall be reduced pro rata
                           to cover the  principal  amount of Auction Rate Bonds
                           equal to such excess;

                                    (III) subject to subclauses  (I) and (II) of
                           this clause (B), if more than one Bid with  different
                           rates is submitted on behalf of such Existing Holder,
                           such  Bids  shall be  considered  valid  first in the
                           ascending order of their  respective  rates until the
                           highest  rate is reached at which such excess  exists
                           and then at such rate up to and  including the amount
                           of such excess; and

                                    (IV)  in  any  such  event,   the  aggregate
                           principal  amount of Outstanding  Auction Rate Bonds,
                           if any,  subject to Bids not valid  under this clause
                           (B) shall be  treated  as the  subject  of a Bid by a
                           Potential Holder at the rate therein specified; and

                           (C) all Sell Orders shall be  considered  valid up to
                  and  including   the  excess  of  the   principal   amount  of
                  Outstanding  Auction Rate Bonds held by such  Existing  Holder
                  over the  aggregate  principal  amount of  Auction  Rate Bonds
                  subject  to Hold  Orders  referred  to in  clause  (A) of this
                  paragraph (v) and valid Bids referred to in clause (B) of this

                  (vi) If more than one Bid for Auction  Rate Bonds is submitted
         on  behalf  of any  Potential  Holder,  each Bid  submitted  shall be a
         separate Bid with the rate and principal amount therein specified.

                  (vii) Any Bid or Sell Order  submitted  by an Existing  Holder
         covering an aggregate  principal amount of Auction Rate Bonds not equal
         to $25,000 or an integral  multiple thereof shall be rejected and shall
         be  deemed  a Hold  Order.  Any Bid  submitted  by a  Potential  Holder
         covering an aggregate  principal amount of Auction Rate Bonds not equal
         to $25,000 or an integral multiple thereof shall be rejected.

                  (viii) Any Bid submitted by an Existing  Holder or a Potential

                  (c)(i)  Not  earlier  than  the  Submission  Deadline  on each
Auction  Date,  the Auction Agent shall  assemble all valid Orders  submitted or
deemed  submitted to it by the  Broker-Dealers  (each such Order as submitted or
deemed submitted by a Broker-Dealer  being hereinafter  referred to individually
as a "Submitted  Hold Order," a "Submitted  Bid" or a "Submitted Sell Order," as
the case may be, or as a "Submitted  Order" and  collectively as "Submitted Hold
Orders,"  "Submitted Bids" or "Submitted Sell Orders," as the case may be, or as
"Submitted Orders") and shall determine:

                           (A) the  excess  of the  total  principal  amount  of
                  Outstanding  Auction Rate Bonds over the sum of the  aggregate
                  principal amount of Outstanding  Auction Rate Bonds subject to
                  Submitted Hold Orders (such excess being hereinafter  referred
                  to as the "Available Auction Rate Bonds"); and

                           (B) from the Submitted Orders whether:

                                    (I)  the  aggregate   principal   amount  of
                           Outstanding  Auction Rate Bonds  subject to Submitted
                           Bids  by  Potential  Holders  specifying  one or more
                           rates equal to or lower than the Maximum Rate;

                  exceeds or is equal to the sum of:

                                    (II)  the  aggregate   principal  amount  of
                           Outstanding  Auction Rate Bonds  subject to Submitted
                           Bids by Existing Holders specifying one or more rates
                           higher than the Maximum Rate; and

                                    (III)  the  aggregate  principal  amount  of
                           Outstanding  Auction Rate Bonds  subject to Submitted
                           Sell Orders

                  (in the event such excess or such equality  exists (other than
                  because the sum of the principal amounts of Auction Rate Bonds
                  in subclauses  (II) and (III) above is zero because all of the
                  Outstanding  Auction Rate Bonds are subject to Submitted  Hold
                  Orders),  such  Submitted  Bids in  subclause  (I) above being
                  hereinafter  referred to collectively as "Sufficient  Clearing
                  Bids"); and

                           (C) if  Sufficient  Clearing  Bids exist,  the lowest
                  rate specified in such Submitted Bids (the "Winning Bid Rate")
                  which if:

                                    (I)  (aa)  each  such   Submitted  Bid  from
                           Existing Holders specifying such lowest rate and (bb)
                           all  other  Submitted  Bids  from  Existing   Holders
                           specifying lower rates were rejected,  thus entitling
                           such  Existing   Holders  to  continue  to  hold  the
                           principal  amount of Auction  Rate  Bonds  subject to
                           such Submitted Bids; and

                                    (II)  (aa)  each  such  Submitted  Bid  from
                           Potential  Holders  specifying  such  lowest rate and
                           (bb) all other Submitted Bids from Potential  Holders
                           specifying lower rates were accepted,

                  would result in such Existing  Holders  described in subclause
                  (I) above continuing to hold an aggregate  principal amount of
                  Outstanding  Auction  Rate  Bonds  which,  when  added  to the
                  aggregate  principal amount of Outstanding  Auction Rate Bonds
                  to  be  purchased  by  such  Potential  Holders  described  in
                  subclause (II) above,  would equal not less than the Available
                  Auction Rate Bonds.

                  (ii)   Promptly   after  the   Auction   Agent  has  made  the
         determinations  pursuant to paragraph (i) of this  subsection  (c), the
         Auction  Agent,  by telecopy  confirmed  in writing,  shall  advise the
         Authority,  the Company  and the  Trustee of the  Maximum  Rate and the
         Minimum Rate and the components  thereof on the Auction Date and, based
         on such  determinations,  the  Auction  Rate  for the  next  succeeding
         Interest Period as follows:

                                                     (A) if Sufficient  Clearing
                                            Bids exist,  that the  Auction  Rate
                                            for  the  next  succeeding  Interest
                                            Period shall be equal to the Winning
                                            Bid Rate so determined;

                           (B) if  Sufficient  Clearing Bids do not exist (other
                  than  because all of the  Outstanding  Auction  Rate Bonds are
                  subject to Submitted  Hold Orders),  that the Auction Rate for
                  the  next  succeeding  Interest  Period  shall be equal to the
                  Maximum Rate; or

                           (C) if all Outstanding Auction Rate Bonds are subject
                  to Submitted  Hold Orders,  that the Auction Rate for the next
                  succeeding Interest Period shall be equal to the Minimum Rate.

                    (d) Existing  Holders  shall  continue to hold the principal
               amount of Auction Rate Bonds that are subject to  Submitted  Hold
               Orders,  and,  based  on  the  determinations  made  pursuant  to
               paragraph (i) of subsection (c) of this Section 3A.03,  Submitted
               Bids and Submitted  Sell Orders shall be accepted or rejected and
               the  Auction  Agent  shall  take such  other  action as set forth
               below:

                  (i) If Sufficient  Clearing Bids have been made, all Submitted
         Sell  Orders  shall be  accepted  and,  subject  to the  provisions  of
         paragraphs (iv) and (v) of this subsection (d), Submitted Bids shall be
         accepted or rejected as follows in the following  order of priority and
         all other Submitted Bids shall be rejected:

                           (A) Existing  Holders'  Submitted Bids specifying any
                  rate  that is  higher  than  the  Winning  Bid  Rate  shall be
                  accepted, thus requiring each such Existing Holder to sell the
                  aggregate  principal  amount of Auction Rate Bonds  subject to
                  such Submitted Bids;

                           (B) Existing  Holders'  Submitted Bids specifying any
                  rate  that is  lower  than  the  Winning  Bid  Rate  shall  be
                  rejected, thus entitling each such Existing Holder to continue
                  to hold the aggregate  principal  amount of Auction Rate Bonds
                  subject to such Submitted Bids;

                           (C) Potential  Holders' Submitted Bids specifying any
                  rate  that is  lower  than  the  Winning  Bid  Rate  shall  be
                  accepted,   thus  requiring  each  such  Potential  Holder  to
                  purchase the aggregate  principal amount of Auction Rate Bonds
                  subject to such Submitted Bids;

                           (D) each Existing Holder's Submitted Bid specifying a
                  rate that is equal to the Winning Bid Rate shall be  rejected,
                  thus  entitling  such Existing  Holder to continue to hold the
                  aggregate  principal  amount of Auction Rate Bonds  subject to
                  such Submitted Bid, unless the aggregate  principal  amount of
                  Outstanding  Auction Rate Bonds subject to all such  Submitted
                  Bids shall be  greater  than the  principal  amount of Auction
                  Rate Bonds (the  "remaining  principal  amount")  equal to the
                  excess of the Available  Auction Rate Bonds over the aggregate
                  principal  amount of Auction  Rate Bonds  subject to Submitted
                  Bids  described in clauses (B) and (C) of this  paragraph (i),
                  in which  event such  Submitted  Bid of such  Existing  Holder
                  shall be rejected in part,  and such Existing  Holder shall be
                  entitled to continue to hold the  principal  amount of Auction
                  Rate  Bonds  subject  to such  Submitted  Bid,  but only in an
                  amount equal to the aggregate principal amount of Auction Rate
                  Bonds obtained by multiplying the remaining  principal  amount
                  by a fraction the  numerator  of which shall be the  principal
                  amount of Outstanding Auction Rate Bonds held by such Existing
                  Holder  subject to such  Submitted Bid and the  denominator of
                  which shall be the sum of the principal  amount of Outstanding
                  Auction Rate Bonds subject to such  Submitted Bids made by all
                  such  Existing  Holders  that  specified  a rate  equal to the
                  Winning Bid Rate; and

                           (E) each Potential  Holder's Submitted Bid specifying
                  a rate that is equal to the Winning Bid Rate shall be accepted
                  but only in an amount equal to the principal amount of Auction
                  Rate Bonds obtained by multiplying the excess of the aggregate
                  principal  amount of  Available  Auction  Rate  Bonds over the
                  aggregate  principal  amount of Auction Rate Bonds  subject to
                  Submitted  Bids  described in clauses (B), (C) and (D) of this
                  paragraph  (i) by a fraction  the  numerator of which shall be
                  the aggregate  principal  amount of  Outstanding  Auction Rate
                  Bonds  subject to such  Submitted Bid and the  denominator  of
                  which shall be the sum of the principal amounts of Outstanding
                  Auction Rate Bonds subject to Submitted  Bids made by all such
                  Potential  Holders that  specified a rate equal to the Winning
                  Bid Rate.

                  (ii) If  Sufficient  Clearing  Bids have not been made  (other
         than because all of the  Outstanding  Auction Rate Bonds are subject to
         Submitted Hold Orders),  subject to the provisions of paragraph (iv) of
         this subsection (d), Submitted Orders shall be accepted or

         rejected as follows in the  following  order of priority  and all other
         Submitted Bids shall be rejected:

                                                     (A)    Existing    Holders'
                                            Submitted  Bids  specifying any rate
                                            that is equal  to or lower  than the
                                            Maximum Rate shall be rejected, thus
                                            entitling  such Existing  Holders to
                                            continue   to  hold  the   aggregate
                                            principal  amount  of  Auction  Rate
                                            Bonds  subject  to  such   Submitted
                                            Bids;

                  rate that is equal to or lower than the Maximum  Rate shall be
                  accepted,  thus requiring  such Potential  Holders to purchase
                  the aggregate  principal  amount of Auction Rate Bonds subject
                  to such Submitted Bids; and

                           (C) each Existing  Holder's  Submitted Bid specifying
                  any  rate  that  is  higher  than  the  Maximum  Rate  and the
                  Submitted  Sell  Order  of  each  Existing   Holder  shall  be
                  accepted,  thus entitling each Existing  Holder that submitted
                  any such  Submitted  Bid or  Submitted  Sell Order to sell the
                  Auction Rate Bonds subject to such  Submitted Bid or Submitted
                  Sell Order,  but in both cases only in an amount  equal to the
                  aggregate  principal  amount of Auction Rate Bonds obtained by
                  multiplying  the  aggregate  principal  amount of Auction Rate
                  Bonds  subject to  Submitted  Bids  described in clause (B) of
                  this paragraph (ii) by a fraction the numerator of which shall
                  be the aggregate  principal amount of Outstanding Auction Rate
                  Bonds held by such Existing  Holder  subject to such Submitted
                  Bid or Submitted Sell Order and the denominator of which shall
                  be the aggregate  principal amount of Outstanding Auction Rate

                  Orders.

                    (iii) If all  Outstanding  Auction Rate Bonds are subject to
               Submitted Hold Orders, all Submitted Bids shall be rejected.

                  (iv) If, as a result of the procedures  described in paragraph
         (i) or (ii) of this  subsection  (d),  any  Existing  Holder  would  be
         entitled or required to sell, or any Potential Holder would be entitled
         or required to purchase,  a principal amount of Auction Rate Bonds that
         is not equal to $25,000 or an  integral  multiple  thereof  the Auction
         Agent  shall,  in such  manner  as,  in its sole  discretion,  it shall
         determine,  round up or down the principal amount of Auction Rate Bonds
         to be purchased or sold by any Existing  Holder or Potential  Holder so
         that the  principal  amount of Auction Rate Bonds  purchased or sold by
         each Existing  Holder or Potential  Holder shall be equal to $25,000 or
         an integral multiple thereof.

                  (v) If, as a result of the  procedures  described in paragraph
         (i) of this subsection  (d), any Potential  Holder would be entitled or
         required to purchase less than $25,000 principal amount of Auction Rate
         Bonds,  the  Auction  Agent  shall,  in such  manner  as,  in its  sole
         discretion,  it  shall  determine,  allocate  Auction  Rate  Bonds  for
         purchase  among  Potential  Holders so that only  Auction Rate Bonds in
         principal amounts of $25,000 or an integral

                                                      IIIA-16

         multiple  thereof are purchased by any Potential  Holder,  even if such
         allocation  results  in one or  more  of  such  Potential  Holders  not
         purchasing any Auction Rate Bonds.

                  (e) Based on the results of each  Auction,  the Auction  Agent
shall  determine  the  aggregate  principal  amount of Auction  Rate Bonds to be
purchased and the aggregate principal amount of Auction Rate Bonds to be sold by
Potential  Holders  and  Existing  Holders on whose  behalf  each  Broker-Dealer
submitted  Bids or Sell Orders and, with respect to each  Broker-Dealer,  to the
extent that such  aggregate  principal  amount of Auction  Rate Bonds to be sold
differs  from such  aggregate  principal  amount  of  Auction  Rate  Bonds to be
purchased,  determine to which other Broker-Dealer or Broker-Dealers  acting for
one or more purchasers  such  Broker-Dealer  shall deliver,  or from which other
Broker-Dealer  or  Broker-Dealers  acting for one or more  sellers  such Broker-
Dealer shall receive, as the case may be, Auction Rate Bonds.

                  SECTION 3A.04. Auction Rate-Inverse Rate Bonds: Certain Orders
Not Permitted;  Purchases and  Cancellations.  (a) None of the Authority nor the
Company nor any Affiliate  thereof may submit an Order in any Auction  except as
set forth in the next sentence.  Any  Broker-Dealer  that is an Affiliate of the
Company may not submit Bids to purchase Auction Rate Bonds in an Auction for its
own account,  provided that affiliated Broker-Dealers may submit Hold Orders and
Sell Orders in Auctions  with respect to Auction Rate Bonds  otherwise  acquired
during any Auction Rate-Inverse Rate Period for its own account.

                  (b) While the Bonds bear  interest  at an  Auction  Rate and a
related  Inverse Rate during an Auction  Rate-Inverse  Rate Period,  neither the
Authority  nor the  Company,  nor the Trustee on behalf of the  Authority or the
Company,  shall purchase or otherwise  acquire Auction Rate Bonds unless, on the
date of any such  purchase or  acquisition,  the  Authority,  the Company or the
Trustee,  as the case may be,  purchases or acquires Regular Linked Auction Rate
Bonds and Inverse  Rate Bonds or Special  Linked  Auction Rate Bonds and Inverse
Rate Bonds or an equal  aggregate  principal  amount of  Auction  Rate Bonds and
Inverse Rate Bonds.

                  (c) Neither the Authority nor the Company shall deliver to the
Trustee  for  cancellation,  and the  Trustee,  at the  request  of  either  the
Authority or the Company,  shall not cancel,  Auction Rate Bonds or Inverse Rate
Bonds  unless (i) the  Authority  or the  Company  delivers  to the  Trustee for
cancellation  or the Trustee  cancels,  as the case may be, (A)  Regular  Linked
Auction Rate Bonds and Inverse Rate Bonds or Special  Linked  Auction Rate Bonds
and Inverse  Rate Bonds or (B) an equal  aggregate  principal  amount of Auction
Rate Bonds and Inverse Rate Bonds or (ii) the Authority or the Company  delivers
to the Trustee for  cancellation  on a Redemption  Date or the  Trustee,  at the
request of the  Authority  or the  Company,  cancels on a  Redemption  Date,  an
aggregate  principal  amount  of  Inverse  Rate  Bonds  equal  to the  aggregate
principal amount of Auction Rate Bonds being redeemed pursuant to subsection (c)
of Section 5.01(c)(ii) on such Redemption Date.

                    SECTION 3A.05.  Auction Rate-Inverse Rate Bonds: Deposit and
               Application  of  Interest  Payments.   (a)  Pursuant  to  Section
               9.02(a)(i),   the  Company   shall  pay  to  the   Registrar  and
               -----------------  Paying  Agent not later than 12:00  Noon,  New
               York City time, on the second Business Day next

preceding  each  Regular  Interest  Payment  Date an  aggregate  amount of funds
available  on the  next  Business  Day in The  City  of New  York  equal  to the
aggregate amount of interest payable on the Bonds of each series on such Regular
Interest  Payment Date. The aggregate amount of interest payable on the Bonds of
each series on each  Interest  Payment  Date  therefor  shall be  calculated  by
applying the Linked Rate to the aggregate  principal  amount of the  Outstanding
Bonds of each series for which interest is to be paid and  multiplying  such sum
by the actual number of days in the Interest Period concerned divided by 365 and
rounding the  resultant  figure to the nearest  cent (half a cent being  rounded
upwards).

                  (b) So long as no Payment Default has previously  occurred and
is continuing and the ownership of the Auction Rate Bonds and Inverse Rate Bonds
is maintained in book-entry form by the Securities Depository, the Trustee shall
send by 12:15 P.M.,  New York City time, on the Business Day next preceding each
Regular Interest  Payment Date a notice in  substantially  the form of Exhibit J
hereto  to the  Auction  Agent  and to the  registered  owners  of the  Bonds by
telecopy or similar means if the aggregate amount of funds available as provided
in  subsection  (a) of this Section 3A.05 is  insufficient  to pay the aggregate
amount of interest  payable on the Bonds of each series on such Regular Interest
Payment  Date  pursuant  to  subsection  (a) of  this  Section  3A.05.  If  such
insufficiency  is cured within three  Business Days after such Regular  Interest
Payment  Date,  the  Trustee  shall   immediately   send  a  notice  thereof  in
substantially  the form of  Exhibit  K hereto  to the  Auction  Agent and to the
registered owners of the Bonds by telecopy or similar means.

                  (c) On any Initial  Interest  Payment Date after the effective
date of a Change in the  Interest  Rate  Mode to an  Auction  Rate-Inverse  Rate
Period, the Registrar and Paying Agent shall pay to the Auction Agent, on behalf
of the  holders of Auction  Rate  Bonds,  out of amounts  made  available  to it
pursuant  to  subsection  (a) of  Section  3A.05  on the  immediately  preceding
Business Day on account of interest on the Auction  Rate Bonds,  an amount equal
to the product of (i) a fraction,  the  numerator of which is the number of days
in the Initial  Interest  Period and the denominator of which is 360, times (ii)
the Service  Charge Rate on the effective  date of a Change in the Interest Rate
Mode to an Auction  Rate-Inverse Rate Period times (iii) the aggregate principal
amount of the  Outstanding  Auction Rate Bonds on the effective date of a Change
in the Interest Rate Mode to an Auction Rate-Inverse Rate Period.

                  (d) On the Interest Payment Date for each Subsequent  Interest
Period  immediately  following an Auction  Date,  the Registrar and Paying Agent
shall pay to the Auction  Agent,  on behalf of the holders of Auction Rate Bonds
in respect of which interest is to be paid on such Interest Payment Date, out of
amounts made  available to it pursuant to subsection (a) of Section 3A.05 on the
immediately  preceding  Business Day on account of interest on such Auction Rate
Bonds, an amount equal to the product of (i) a fraction,  the numerator of which
is the number of days in such Interest  Period and the  denominator  of which is
360,  times (ii) the amount of the Service Charge Rate times (iii) the aggregate
principal  amount of such  Auction Rate Bonds which were not Linked with Inverse
Rate Bonds at the close of  business  on the  Regular  Record  Date  immediately
preceding such Auction Date.

                  SECTION 3A.06. Auction Rate-Inverse Rate Bonds: Calculation of
Maximum Rate,  Minimum Rate and Overdue Rate. The Auction Agent shall  calculate
the Maximum Rate and the Minimum Rate on each Auction  Date. If all Auction Rate
Bonds are Linked with Inverse Rate Bonds at the close of business on any Regular
Record Date, the Auction Agent shall  calculate the Minimum Rate on the Business
Day  immediately  preceding  the  first  day of the next  succeeding  Subsequent
Interest  Period.  If the  ownership  of the  Auction  Rate  Bonds is no  longer
maintained in book-entry  form by the Securities  Depository,  the Trustee shall
calculate the Maximum Rate on the Business Day  immediately  preceding the first
day of  each  Subsequent  Interest  Period  commencing  after  the  delivery  of
certificates  representing the Auction Rate Bonds pursuant to Section 2.03. If a
Payment  Default shall have  occurred,  the Trustee shall  calculate the Overdue
Rate (i) as of the first day of the Subsequent  Interest Period commencing on or
immediately  prior to the date on which such Payment Default shall have occurred
and (ii) on the first day of any Subsequent Interest Period commencing after the
occurrence  of such Payment  Default to and including  the  Subsequent  Interest
Period,  if any,  commencing  less than two Business Days after the cure of such
Payment  Default.  The Trustee shall  calculate the Applicable  Factors for each
Subsequent Interest Period. The determination of the Applicable Factors shall in
the absence of manifest error be final and binding upon all parties.

                  SECTION 3A.07. Auction Rate-Inverse Rate Bonds: Computation of
Interest.  (a) From and after the time that  ownership of the Auction Rate Bonds
and  Inverse  Rate  Bonds is no  longer  maintained  in  book-entry  form by the
Securities  Depository,  the  Trustee  shall  calculate  the amount of  interest
distributable  to (i)  holders of Regular  Auction  Rate Bonds for any  Interest
Period by applying the Applicable Factor for Regular Auction Rate Bonds for such
Interest Period to the aggregate  principal amount of Regular Auction Rate Bonds
multiplying  such  sum by the  actual  number  of  days in the  Interest  Period
concerned  divided by 360 and rounding the resultant  figure to the nearest cent
(half a cent being  rounded  upwards) and (ii)  holders of Regular  Inverse Rate
Bonds for any  Interest  Period by applying  the  Applicable  Factor for Regular
Inverse Rate Bonds for such Interest Period to the aggregate principal amount of
Regular Inverse Rate Bonds  multiplying such sum by the actual number of days in
the Interest Period  concerned  divided by 365 and rounding the resultant figure
to the nearest cent (half a cent being rounded upwards).

                  (b) So long as the  ownership  of the  Auction  Rate Bonds and
Inverse  Rate  Bonds  is  maintained  in  book-entry   form  by  the  Securities
Depository,  the Trustee shall calculate the Interest Amount with respect to (i)
Regular  Auction  Rate Bonds and Special  Auction  Rate Bonds for each  Interest
Period by applying  the  Applicable  Factor for Regular  Auction  Rate Bonds and
Special  Auction  Rate  Bonds,  respectively,  for such  Interest  Period to the
principal amount of $1,000, multiplying such sum by the actual number of days in
the Interest Period concerned divided by 360 and truncating the resultant figure
to six figures to the right of the decimal  point and (ii) Regular  Inverse Rate
Bonds,  Regular  Linked  Auction  Rate Bonds and Inverse  Rate Bonds and Special
Linked  Auction  Rate  Bonds and  Inverse  Rate  Bonds,  respectively,  for each
Interest  Period by applying  the  Applicable  Factor for Regular  Inverse  Rate
Bonds,  Regular  Linked  Auction  Rate Bonds and Inverse  Rate Bonds and Special
Linked  Auction  Rate  Bonds and  Inverse  Rate  Bonds,  respectively,  for such
Interest Period to the principal  amount of $1,000,  multiplying such sum by the
actual number of days

in the Interest  Period  concerned  divided by 365 and  truncating the resultant
figure to six figures to the right of the decimal point.

                  SECTION 3A.08. Auction  Rate-Inverse Rate Bonds:  Notification
of Rates, Amounts and Payment Dates. (a) So long as the ownership of the Auction
Rate Bonds and the Inverse Rate Bonds is maintained  in  book-entry  form by the
Securities  Depository,  the Trustee shall advise the  Securities  Depository of
each  Regular  Record  Date at least two  Business  Days prior  thereto  and the
Registrar and Paying Agent shall request the Securities Depository to provide it
with a position  listing  showing at the close of business on each such  Regular
Record Date the  aggregate  principal  amounts of:  Regular  Auction Rate Bonds,
Special Auction Rate Bonds,  Regular Inverse Rate Bonds,  Regular Linked Auction
Rate Bonds and Inverse  Rate Bonds and  Special  Linked  Auction  Rate Bonds and
Inverse Rate Bonds,  respectively,  and, in the case of the Stated Maturity,  of
the aggregate principal amounts payable on the Stated Maturity to the holders of
Regular  Auction Rate Bonds,  Special  Auction Rate Bonds,  Regular Inverse Rate
Bonds,  Regular  Linked  Auction  Rate Bonds and Inverse  Rate Bonds and Special
Linked Auction Rate Bonds and Inverse Rate Bonds, respectively.  On the basis of
such  position  listing,  the  Registrar  and Paying Agent shall  determine  the
aggregate  amounts of interest  distributable  on the next  succeeding  Interest
Payment Date to the holders of Regular Auction Rate Bonds,  Special Auction Rate
Bonds, Regular Inverse Rate Bonds, Regular Linked Auction Rate Bonds and Inverse
Rate Bonds and  Special  Linked  Auction  Rate  Bonds and  Inverse  Rate  Bonds,
respectively.  In the event the  Credit  Facility  Issuer is  obligated  to make
payments  pursuant to the Credit  Facility with respect to any Interest  Period,
the Trustee shall make available to the Credit  Facility  Issuer any information
obtained  or  determined  by it  pursuant  to this  subsection  (a) in  order to
facilitate  the payment of any amounts due under this  Indenture  in  accordance
with the terms of the Credit Facility.

                  (b) Promptly  after a Change in the  Interest  Rate Mode to an
Auction  Rate-Inverse  Rate Period and each Regular Interest Payment Date during
an Auction  Rate-Inverse Rate Period, and in any event at least 10 days prior to
the next Interest  Payment Date  following a Change in the Interest Rate Mode to
an Auction Rate-Inverse Rate Period or each Regular Interest Payment Date during
an Auction  Rate-Inverse  Rate  Period,  as the case may be, the  Trustee  shall
advise:

                           (i) the Auction Agent,  so long as no Payment Default
                  has  occurred  and is  continuing  and  the  ownership  of the
                  Auction Rate Bonds is  maintained  in  book-entry  form by the
                  Securities  Depository,  and any Registrar and Paying Agent of
                  such next succeeding  Interest  Payment Date and, if such next
                  succeeding  Interest  Payment  Date  is  not  also  a  Regular
                  Interest Payment Date, of the next succeeding Regular Interest
                  Payment Date;

                           (ii)  any   Registrar   and  Paying   Agent  and  the
                  Securities Depository, so long as the ownership of the Auction
                  Rate  Bonds  or  the  Inverse  Rate  Bonds  is  maintained  in
                  book-entry   form  by  the  Securities   Depository,   of  the
                  Applicable  Factors and the  Interest  Amounts with respect to
                  each Interest Period commencing on such Change

               Date, as the case may be; and

                           (iii)  the  Auction  Agent,  so  long  as no  Payment
                  Default has occurred and is  continuing  and the  ownership of
                  the Auction Rate Bonds is maintained in book-entry form by the
                  Securities  Depository,  and any Registrar and Paying Agent of
                  the amount payable to the Auction Agent pursuant to subsection
                  (c) or (d) of Section 3A.05 on such next  succeeding  Interest
                  Payment  Date and, if such next  succeeding  Interest  Payment
                  Date is not  also a  Regular  Interest  Payment  Date,  of the
                  amount so  payable  on the next  succeeding  Regular  Interest
                  Payment Date.

In the event that any day that is scheduled to be an Interest Payment Date shall
be changed after the Trustee  shall have given the notice  referred to in clause
(i) of the preceding sentence,  not later than 9:15 A.M., New York City time, on
the Business Day next preceding the earlier of the new Interest  Payment Date or
the old Interest  Payment  Date,  the Trustee will, by such means as the Trustee
deems  practicable,  give notice of such change to the Auction Agent, so long as
no Payment  Default has  occurred  and is  continuing  and the  ownership of the
Auction  Rate  Bonds  is  maintained  in  book-entry   form  by  the  Securities
Depository, and to any Registrar and Paying Agent.

                  (c) By  10:00  A.M.,  New  York  City  time,  on each  Regular
Interest  Payment  Date,  the  Trustee  shall  advise the  Auction  Agent of the
Applicable  Factor with respect to Regular Auction Rate Bonds and the Applicable
Inverse Rate for the Interest Period commencing on such Regular Interest Payment
Date.

                  SECTION 3A.09. Auction Rate-Inverse Rate Bonds:  Adjustment in
Percentage.  1. The Market Agent may adjust the  percentage  used in determining
the Minimum Rate and the Applicable  Percentage  used in determining the Maximum
Rate if any such adjustment is necessary, in the judgment of the Market Agent to
reflect any Change of Preference Law or to conform to market  practice such that
the Maximum Rate and Minimum Rate shall have  substantially  equal market values
before and after such Change of Preference Law or change in market practice.  In
making any such adjustment as a result of a Change of Preference Law, the Market
Agent shall take the following  factors,  as in existence  both before and after
such  Change of  Preference  Law,  into  account:  (i)  short-term  taxable  and
tax-exempt  market rates and indices of such short-term  rates;  (ii) the market
supply and demand for short-term tax-exempt  securities;  (iii) yield curves for
short- term and long-term  tax-exempt  securities or obligations having a credit
rating that is comparable to the Bonds;  (iv) general economic  conditions;  and
(v) economic and financial  factors present in the securities  industry that may
affect or that may be relevant to the Bonds.  In making any such  adjustment  to
conform to market  practice,  the Market  Agent  shall  take into  account  such
factors as the Market Agent deems relevant,  including the terms of auction rate
bonds of other  issuers.  Upon the  occurrence  and during the  continuance of a
Company Downgrade Event, the Bond Insurer shall have the right to consent to any
adjustment  to the  percentage  used  to  determine  the  Minimum  Rate  and the
Applicable  Percentages  used to determine the Maximum Rate, which consent shall
not be unreasonably withheld.

                  2. The Market Agent shall  communicate  its  determination  to
adjust the percentage  used in  determining  the Minimum Rate and the Applicable
Percentage  used in determining the Maximum Rate pursuant to subsection 1 hereof
by means of a written  notice  delivered  at least 10 days prior to the  Auction
Date on which the Market  Agent  desires to effect the change to the  Authority,
the  Trustee,   the  Auction  Agent,   the  Bond  Insurer  and  the  Company  in
substantially  the form  attached  hereto as, or  containing  substantially  the
information  contained in,  Exhibit F. Such notice shall be effective only if it
is  accompanied  by the form of opinion that Bond Counsel has advised the Market
Agent that it expects to be able to give on such Auction Date to the effect that
such adjustment is authorized by this Indenture,  is permitted under the Act and
will not have an adverse  effect on the  exclusion  of  interest on the Bonds of
each series from gross income for federal income tax purposes. The Auction Agent
is required to mail notice  thereof to the Existing  Holders within two Business
Days of receipt thereof.

                  3. An adjustment in the  percentage  used in  determining  the
Minimum Rate and the Applicable  Percentage used in determining the Maximum Rate
shall take effect on an Auction Date only if (A) the  Trustee,  the Bond Insurer
and the  Auction  Agent  receive,  by 11:00  A.M.  (New York  City  time) on the
Business Day  immediately  preceding  such Auction Date, a certificate  from the
Market Agent by telecopy or similar means,  in  substantially  the form attached
hereto as, or containing  substantially the information contained in, Exhibit H,
(i) authorizing the adjustment of the percentage used in determining the Minimum
Rate and the Applicable  Percentage  used in determining  the Maximum Rate which
shall be specified in such authorization,  and (ii) confirming that Bond Counsel
expects to be able to give an opinion on such  Auction  Date to the effect  that
the  adjustment in the percentage  used in determining  the Minimum Rate and the
Applicable Percentage used in determining the Maximum Rate is authorized by this
Section 3A.09, is permitted under the Act and will not have an adverse effect on
the  exclusion  of interest  on the Bonds of each  series from gross  income for
federal  income tax  purposes  and (B) the  Trustee,  the Bond  Insurer  and the
Auction Agent receive by 9:30 A.M. (New York City time) on such Auction Date, an
opinion of Bond Counsel to the effect that the adjustment in the percentage used
in  determining  the  Minimum  Rate  and  the  Applicable   Percentage  used  in
determining the Maximum Rate is authorized by this Indenture, is permitted under
the Act and will not have an adverse  effect on the exclusion of interest on the
Bonds of each series from gross income for federal income tax purposes.

                  SECTION  3A.10.   Mandatory  Auction  Rate  Bonds  Tender  for
Purchase.  So long as the  ownership of the Auction Rate Bonds is  maintained in
book-entry  form  by  the  Securities  Depository,  at  any  time  prior  to the
Submission Deadline on any Auction Date, any holder of Inverse Rate Bonds (other
than the  Authority,  the  Company or any  Affiliate  thereof)  (i) may notify a
Broker-  Dealer that such holder intends to submit a Bid at the Minimum Rate for
a  specified  principal  amount of  Auction  Rate  Bonds in the  Auction on such
Auction Date in order to link the same with all or a portion of its Inverse Rate
Bonds and (ii) if such Bid is  unsuccessful,  in whole or in part,  may elect no
later than the second  Business Day succeeding such Auction Date to require that
Regular  Auction  Rate  Bonds  in an  aggregate  principal  amount  equal to the
unsuccessful  portion of such Bid be  tendered  to such  holder for  purchase (a
"Tender  Demand") on the seventh  Business  Day  preceding  the next  succeeding
Auction Date (a "Tender Date"). The purchase price shall equal the principal

amount of Regular  Auction  Rate Bonds being  purchased  plus accrued and unpaid
interest  thereon to the Tender  Date at the  Applicable  Auction  Rate less the
Service Charge Rate (the "Tender Price"). A holder of Regular Auction Rate Bonds
who  receives  notice that all or any portion of its Regular  Auction Rate Bonds
has been  selected for purchase by a holder of Inverse Rate Bonds who has made a
Tender Demand,  shall tender such Auction Rate Bonds for purchase by such holder
of Inverse Rate Bonds at the Tender Price on the Tender Date therefor.  A holder
of Inverse Rate Bonds who has made a Tender  Demand  shall  purchase the Regular
Auction  Rate  Bonds  tendered  to it on the Tender  Date for the  Tender  Price
therefor. Notice of a Tender Demand shall be given, and the Regular Auction Rate
Bonds to be so purchased  shall be selected,  by the Auction Agent in accordance
with the Auction Agency Agreement.

                                          CHANGES IN THE ADJUSTABLE RATE

                  SECTION 4.01.  Optional  Conversion by Authority.  1. Prior to
the Fixed Rate  Conversion  Date, at the times  specified  below,  the Bonds, in
whole or in part, shall cease to bear interest at the Adjustable Rate then borne
by the Bonds and shall bear interest at such different  Adjustable Rate as shall
be  specified  by the  Authority,  at the request of the  Company,  in a written
notice  delivered at least 15 days prior to the proposed  effective  date of the
Change in the Interest Rate Mode to the Trustee, the Market Agent, the Registrar
and Paying Agent,  any Support Facility Issuer and any Rating Agency then rating
the Bonds (and to the Auction Agent and the Securities Depository if such Change
in the  Interest  Rate Mode is to or from an Auction Rate during an Auction Rate
Period  or  an  Auction  Rate  and  related   Inverse  Rate  during  an  Auction
Rate-Inverse  Rate  Period) in  substantially  the form  attached  hereto as, or
containing  substantially the information contained in, Exhibit A; provided that
during any Auction  Rate-Inverse Rate Period the rate of interest on the Auction
Rate-Inverse  Rate Bonds  subject to such  proposed  Change in the Interest Rate
Mode shall not be  adjusted  to a  different  Adjustable  Rate  until  after the
expiration of a ten (10) year no-call  period which period shall commence on the
effective  date  of  a  Change  in  the  Interest  Rate  Mode  to  such  Auction
Rate-Inverse  Rate Period;  provided,  further,  that any Change in the Interest
Rate Mode from an Auction  Rate-Inverse  Rate Period may be  effected  only upon
purchase of Auction Rate Bonds and Inverse Rate Bonds  subject to such  proposed
Change  in the  Interest  Rate  Mode at a price  equal to the  principal  amount
thereof  plus the  premium  on the  Inverse  Rate Bonds  referred  to in Section
5.01(d),  if any. A Change in the Interest Rate Mode may only be effected on the
last Interest Payment Date for a Calculation Period,  Auction Period or Interest
Period,  as the case may be;  provided  that a Change in the Interest  Rate Mode
during a  Commercial  Paper Rate Period may only be effected on any Business Day
upon  purchase of the Bonds  pursuant to subsection 1 of Section 5.02 at a price
equal to the principal  amount thereof.  A notice of Change in the Interest Rate
Mode shall be effective  only if it is  accompanied  by the form of opinion that
Bond Counsel  expects to be able to give on the proposed  effective date of such
Change in the Interest  Rate Mode to the effect that such Change in the Interest
Rate Mode is authorized by this  Indenture,  is permitted under the Act and will
not have an adverse effect on the exclusion of interest on such Bonds from gross
income for  federal  income tax  purposes.  Upon the  occurrence  and during the
continuance of a Company  Downgrade Event, the Bond Insurer shall have the right
to consent to any  conversion of the Bonds to the  Commercial  Paper Rate or any
interest rate mode with an interest  period  longer than 30 days,  which consent
shall not be unreasonably  withheld.  It also shall be a condition to any change
in the  Interest  Rate of Mode from any Term  Rate at a time  when the  purchase
price  payable  includes an amount  representing  premium that (i) the Liquidity
Facility then in effect shall permit amounts to be drawn  thereunder to pay such
premium or (ii) Available  Moneys have been provided to the Registrar and Paying
Agent in an amount sufficient to pay such purchase price in full, including such
premium.

                  In the case of any Change in the Interest  Rate Mode to a Term
Rate,  the notice  required  by this  section  shall  specify  the length of the
Calculation  Period and, unless otherwise  specified,  such  Calculation  Period
shall thereafter apply to the Bonds until the earliest to occur of (i) the Fixed
Rate  Conversion Date pursuant to Section 4.02, or (ii) a Change in the Interest
Rate Mode effected  pursuant to this Section 4.01. Any change in the Calculation
Period during a Term Rate Period shall be deemed an optional conversion pursuant
to this  Section  4.01  and may not be made  unless  all the  requirements  of a
conversion pursuant to this Section 4.01 are met.

                  2. The Trustee  shall mail,  or cause the Registrar and Paying
Agent to mail, the notice received pursuant to subsection 1 of this Section 4.01
on or before the third Business Day after receipt thereof to the Bondholders.

                    3. A Change in the Interest Rate Mode to an Adjustable  Rate
               shall be effective

                  (A) with respect to any Change in the Interest  Rate Mode from
an Auction  Rate during an Auction  Rate Period or an Auction Rate and a related
Inverse  Rate during an Auction  Rate-  Inverse Rate  Period,  the Trustee,  any
Credit Facility Issuer (if any) and the Auction Agent shall receive:

be. If the  condition  referred  to in (B) above is not met with  respect to any
Change in the  Interest  Rate Mode from an Auction  Rate during the Auction Rate
Period,  the Auction Rate for the next succeeding  Auction Period shall be equal

Inverse Rate during an Auction  Rate-Inverse Rate Period is not met, the Trustee
shall mail, or cause the  Registrar  and Paying Agent to mail to the  Authority,
the Company and the Holders  notice thereof in  substantially  the form attached
hereto as, or containing  substantially the information  contained in, Exhibit Q
within 3 Business Days after the failure to meet any of such conditions.

                  SECTION  4.02.  Optional  Conversion  to  Fixed  Rate.  1. The
Authority reserves the right, at the request of the Company,  to fix the rate of
interest  per annum  which the Bonds  will  bear,  in whole or in part,  for the
balance of the term thereof; provided however, that if the Bonds subject to such
proposed  conversion  to a Fixed Rate bear  interest  at an  Auction  Rate and a
related Inverse Rate during an Auction  Rate-Inverse Rate Period,  the Authority
shall not exercise such right and the Company shall not request the Authority to
exercise such right prior to the  expiration  of a ten (10) year no-call  period
which period shall  commence on the  effective  date of a Change in the Interest
Rate Mode to such Auction Rate-Inverse Rate Period; provided,  further, that any
conversion  to a Fixed Rate, in whole or in part,  from an Auction  Rate-Inverse
Rate Period may only be  effective  upon  purchase of the Auction Rate Bonds and
the Inverse Rate Bonds at a price equal to the principal amount thereof plus the
premium on the Inverse Rate Bonds referred to in Section 5.01(d), if any. In the
event  the  Authority,  at the  request  of the  Company,  as  herein  provided,
exercises  its Option to Convert,  the Bonds shall cease to bear interest at the
Adjustable  Rate then  borne by the Bonds and shall bear  interest  at the Fixed
Rate until  maturity,  subject to the terms and  conditions  hereof (the date on
which the Fixed Rate shall  take  effect  being  herein  called the "Fixed  Rate
Conversion  Date"). The Option to Convert may be exercised at any time through a
written notice given by the Authority, at the direction of the Company, not less
than 15 nor more than 45 days prior to the proposed Fixed Rate  Conversion  Date
to the Trustee, the Registrar and Paying Agent, any Support Facility Issuer,

the Market  Agent and any Rating  Agency then rating the Bonds at the request of
the Company (and the Auction Agent, and the Securities Depository in the case of
any change to a Fixed Rate from an Auction Rate during an Auction Rate Period or
an Auction Rate and a related Inverse Rate during an Auction  Rate-Inverse  Rate
Period),   in   substantially   the  form  attached  hereto  as,  or  containing
substantially the information contained in, Exhibit A. The Fixed Rate Conversion
Date may only be the  last  Interest  Payment  Date  for a  Calculation  Period,
Auction  Period or Interest  Period,  as the case may be;  provided that a Fixed
Rate Conversion Date that immediately follows a Commercial Paper Rate Period may
be on any Business Day upon  purchase of the Bonds  pursuant to  subsection 3 of
Section  5.03 at a price  equal to the  principal  amount  thereof.  A notice of
conversion to a Fixed Rate shall be effective  only if it is  accompanied by the
form of opinion that Bond Counsel  expects to give on the Fixed Rate  Conversion
Date to the effect that the  establishment  of the Fixed Rate is  authorized  by
this  Indenture,  is permitted under the Act and will not have an adverse effect
on the exclusion of interest on such Bonds from gross income for federal  income
tax purposes.  Upon the  occurrence and the  continuance of a Company  Downgrade
Event, the Bond Insurer shall have the right to consent to any conversion of the
Bonds to the Fixed Rate, which consent shall not be unreasonably withheld.

                  2. The Trustee  shall mail,  or cause the Registrar and Paying
Agent to mail, the notice received pursuant to subsection 1 of this Section 4.02
on or before the third Business Day after receipt thereof to the Holders.

                  3.       The Fixed Rate shall take effect only if

                  (A) with respect to a change to the Fixed Rate from an Auction
Rate during an Auction Rate Period or an Auction Rate and a related Inverse Rate
during an Auction  Rate-Inverse Rate Period,  the Trustee,  the Bond Insurer and
the Auction Agent shall receive:

                  (i) a certificate of an Authorized  Company  Representative by
         no later  than the tenth day prior to the Fixed  Rate  Conversion  Date
         stating that a written  agreement  has been entered into by the Company
         and a firm or firms of investment  bankers to remarket the Bonds on the
         Fixed  Rate  Conversion  Date at a price of not less  than  100% of the
         principal amount thereof, which written agreement (i) may be subject to
         reasonable  terms and  conditions  which in the judgment of the Company
         reflect current market standards regarding  investment banking risk and

         Bond  Counsel  expects  to be able to give an opinion on the Fixed Rate
         Conversion  Date to the  effect  that the  change to the Fixed  Rate is
         authorized by this  Indenture,  is permitted under the Act and will not
         have an adverse  effect on the  exclusion of interest on the Bonds from
         gross income for federal income tax purposes; and

                  (B) with  respect to any  change to a Fixed Rate the  Trustee,
the Bond Insurer (and the Auction  Agent and the Market Agent in the case of any
change to the Fixed Rate from an Auction  Rate during an Auction  Rate Period or
an Auction Rate and related  Inverse Rate during any Auction  Rate-Inverse  Rate
Period) receives on the Fixed Rate Conversion Date:

                  (i) by 9:30  a.m.  (New  York City  time) an  Opinion  of Bond
         Counsel  to the  effect  that  the  conversion  to the  Fixed  Rate  is
         authorized by this  Indenture,  is permitted under the Act and will not

         substantially the form attached hereto as, or containing  substantially
         the  information  contained in,  Exhibit P, from an Authorized  Company
         Representative  that all of the Bonds tendered or deemed  tendered have
         been  purchased at a price equal to the principal  amount  thereof with
         funds provided from the  remarketing  of such Bonds in accordance  with
         the Fixed Rate  Commitment,  and that accrued and unpaid  interest,  if
         any, has been or shall be paid in accordance  with the  Indenture  from
         funds  deposited  with the Trustee,  and that the premium,  if any, has
         been paid from monies deposited with the Trustee.

                  If any of the  conditions  referred to in (A) above is not met
with  respect to any change to the Fixed  Rate from an  Auction  Rate  during an
Auction  Rate  Period or an Auction  Rate and  related  Inverse  Rate during any
Auction Rate-Inverse Rate Period, the Auction Rate during an Auction Rate Period
or the Auction  Rate and related  Inverse  Rate during any Auction  Rate-Inverse
Rate Period, as the case may be, for the next succeeding Auction Period shall be
determined  pursuant to the Auction  Procedures  applicable  to the Auction Rate
Bonds during an Auction Rate Period or the Auction Procedures  applicable to the
Auction  Rate-Inverse Rate Bonds during an Auction Rate- Inverse Rate Period, as
the case may be. If any of the  conditions  referred to in (B) above are not met
with  respect to any change to the Fixed  Rate from an  Auction  Rate  during an
Auction Rate Period, the Auction Rate during an Auction Rate Period for the next
succeeding Auction Period shall be equal to the Maximum Auction Rate, and if any
of the condition referred to in (B) above are not met with respect to any change

Interest  Period  shall be equal to the sum of the Maximum  Rate and the Service
Charge  Rate  as  determined  on  the  applicable  Auction  Date.  If any of the
conditions  referred to in (B) above are not met with respect to any change from
any other  Adjustable  Rate to a Fixed Rate,  the Bonds  shall  continue to bear
interest  at the  Adjustable  Rate then borne by the Bonds and be subject to the

Indenture  applicable  thereto while the Bonds bear interest at such  Adjustable
Rate. If any of the foregoing  conditions to the establishment of the Fixed Rate
(other than with respect to any attempted  change from an Auction Rate during an
Auction  Rate  Period or an Auction  Rate and  related  Inverse  Rate during any
Auction Rate-Inverse Rate Period to a Fixed Rate) are not met, the Trustee shall
mail,  or cause the  Registrar  and Paying Agent to mail to the  Authority,  the
Holders and the  Company,  notice  thereof in  substantially  the form  attached
hereto as, or containing  substantially the information  contained in, Exhibit R
within 3 Business Days after the failure to meet any of said conditions.

                  4. If the Bonds commence to bear interest at the Fixed Rate as
provided  in  this  Section  4.02,  the  interest  rate on  such  Bonds  may not
thereafter be changed to an Adjustable Rate.

                  SECTION 4.03. Conversion  Generally.  1. (A) In the event of a
Change  in the  Interest  Rate  Mode on less  than all the  Bonds of a series or
subseries  to or from an  Auction  Rate and an  Inverse  Rate  during an Auction
Rate-Inverse  Rate Period or to or from an Auction  Rate during an Auction  Rate
Period,  or (B) in the event of a conversion  of the interest  rate on less than
all the Bonds of a series or  subseries to a Fixed Rate from an Auction Rate and
an Inverse  Rate during an Auction  Rate-Inverse  Rate Period or from an Auction
Rate during an Auction Rate Period,  the minimum  aggregate  principal amount of
Bonds that continue to bear, or are adjusted to bear interest at an Auction Rate
and an Inverse Rate for an Auction  Rate-Inverse Rate Period,  shall not be less
than  $20,000,000  for such  Auction  Rate Bonds and such  Inverse  Rate  Bonds,
respectively,  and the minimum aggregate principal amount of Bonds that continue
to bear, or are adjusted to bear interest at an Auction Rate for an Auction Rate
Period, shall not be less than $20,000,000 for such Auction Rate Bonds.

                  2. Upon any  Change in the  Interest  Rate Mode to an  Auction
Rate and an Inverse  Rate  during an Auction  Rate-Inverse  Rate Period or to an
Auction Rate during an Auction Rate Period,  the Authority and the Trustee shall
take all  steps  necessary  to comply  with any  agreement  entered  into with a
Securities Depository or its nominee pursuant to Section 2.03(5) with respect to
such  Change in the  Interest  Rate Mode,  including,  without  limitation,  the
purchase  and  designation  of  sufficient  CUSIP  numbers  to  comply  with the
requirements  of such  Securities  Depository  following  any such Change in the
Interest Rate Mode.

                  3. Except as otherwise  provided in Section 4.03(4) below with
respect to Auction  Rate-Inverse Rate Bonds during an Auction  Rate-Inverse Rate
Period,  if the interest rate on less than all Bonds is to be converted to a new
Adjustable  Rate pursuant to Section 4.01 or to a Fixed Rate pursuant to Section
4.02, the particular  Bonds to be converted  shall be chosen by the Trustee,  or
the Trustee shall direct the  Registrar  and Paying Agent to so choose,  in such
manner as the Trustee or Registrar and Paying Agent in its  discretion  may deem
proper; provided, however, that the portion of any Bond to be converted shall be
in the  principal  amount of  $100,000  or some  integral  multiple of $5,000 in
excess of such  amount  during a  Commercial  Paper  Rate  Period,  a Daily Rate
Period, a Weekly Rate Period or a Monthly Rate Period,  $25,000 or some integral
multiple  thereof  during an Auction  Rate  Period,  or $5,000 or some  integral
multiple thereof at any other time and that, in

                                                       IV-7

<PAGE>



selecting Bonds for conversion,  the Trustee or Registrar and Paying Agent shall
treat  each Bond as  representing  that  number of Bonds  which is  obtained  by
dividing the principal  amount of such  registered Bond in excess of $100,000 by
$5,000 during a Commercial Paper Rate Period, a Daily Rate Period, a Weekly Rate
Period or a Monthly Rate  Period,  $25,000  during an Auction  Rate Period,  and
$5,000 at any other time (such  amounts  being  hereinafter  referred  to as the
"applicable units of principal  amount").  If it is determined that one or more,
but not all of the  $100,000,  $25,000  or  $5,000  units  of  principal  amount
represented  by any such Bond is to be converted,  then upon notice of intention
to convert such  $100,000,  $25,000 or $5,000 unit or units pursuant to Sections
4.01 or 4.02,  as the case may be, the  Holders of such  Bonds  shall  forthwith
surrender  such Bonds to the  Registrar  and Paying Agent for (1) payment of the
purchase price  (including the premium,  if any, and accrued and unpaid interest
to the date fixed for  conversion)  of the  $100,000,  $25,000 or $5,000 unit or
units of principal  amount called for conversion and (2) exchange for a new Bond
or Bonds in the  aggregate  principal  amount of the balance of the principal of
such  Bonds not  subject  to  conversion.  If the  Holders of any such Bond of a
denomination greater than $100,000, $25,000 or $5,000 shall fail to present such
Bond to the Registrar  and Paying Agent,  for payment and exchange as aforesaid,
such Bond  shall,  nevertheless,  become  due and  payable on the date fixed for
conversion  to the extent of the  $100,000,  $25,000 or $5,000  unit or units of
principal amount subject to such conversion (and to that extent only).

                  4. The  interest  rate on Auction  Rate Bonds and Inverse Rate
Bonds during any Auction  Rate-Inverse Rate Period shall be converted in minimum
denominations of $25,000 or integral multiples thereof. So long as the ownership
of the  Auction  Rate  Bonds and the  Inverse  Rate  Bonds  during  any  Auction
Rate-Inverse  Rate Period is  maintained in  book-entry  form by the  Securities
Depository,  the Auction Rate Bonds and Inverse Rate Bonds, the interest rate on
which is  subject  to  conversion  in part,  shall be  selected  by lot from the
Outstanding  Bonds of each series as described  in the  following  sentence.  An
amount  equal to the  percentage  obtained by dividing the  aggregate  principal
amount of  Outstanding  Bonds of each series which are Linked on the record date
selected for the purposes of such conversion,  by the aggregate principal amount
of Outstanding  Bonds of each series on such record date, shall be selected from
Regular  Linked  Auction  Rate Bonds and Inverse  Rate Bonds and Special  Linked
Auction  Rate Bonds and  Inverse  Rate Bonds (on a pro rata basis in  accordance
with the relative  principal amounts  thereof),  the remaining amount of Inverse
Rate Bonds to be converted shall be selected from Regular Inverse Rate Bonds and
the  remaining  amount of Auction Rate Bonds to be  converted  shall be selected
from Regular  Auction  Rate Bonds and Special  Auction Rate Bonds (on a pro rata
basis in accordance with the relative principal amounts thereof); provided, that
if any principal  amount of the Auction Rate Bonds and of the Inverse Rate Bonds
selected as provided  above from Regular  Linked  Auction Rate Bonds and Inverse
Rate Bonds,  Special Linked  Auction Rate Bonds and Inverse Rate Bonds,  Regular
Inverse Rate Bonds, Regular Auction Rate Bonds and Special Auction Rate Bonds is
not equal to $25,000 or an integral multiple thereof, the Trustee shall, in such
manner  as, in its sole  discretion,  it shall  determine,  round up or down the
principal  amounts  so  determined.   The  Trustee  shall  give  the  Securities
Depository  at least two Business  Days notice of the record date selected by it
for the purpose of a  conversion  and obtain from the  Securities  Depository  a
position  listing  showing at the close of  business  as of such record date the
aggregate principal amounts of: Regular Auction Rate

                                                       IV-8

<PAGE>



Bonds,  Special Auction Rate Bonds,  Regular Inverse Rate Bonds,  Regular Linked
Auction Rate Bonds and Inverse Rate Bonds and Special  Linked Auction Rate Bonds
and Inverse Rate Bonds, respectively. On the basis of such position listing, the
Trustee  shall  calculate  the  percentage  obtained by dividing  the  aggregate
principal  amount of  Outstanding  Bonds of each series which are Linked on such
record  date by the  aggregate  principal  amount of  Outstanding  Bonds of each
series on such record date,  and determine  therefrom  the  aggregate  principal
amounts to be converted and purchase  prices per $1,000 (plus accrued and unpaid
interest  thereon to the date fixed for  conversion)  of  Regular  Auction  Rate
Bonds,  Special Auction Rate Bonds,  Regular Inverse Rate Bonds,  Regular Linked
Auction Rate Bonds and Inverse Rate Bonds and Special  Linked Auction Rate Bonds
and Inverse Rate Bonds, respectively.

                  5.  Notwithstanding   anything  in  this  Article  IV  to  the
contrary,  during a Term Rate Period,  the  Authority may not effect a Change in
the  Interest  Rate Mode  pursuant  to Section  4.01 and the  Authority  may not
exercise its option to convert to a Fixed Rate  pursuant to Section 4.02 if such
action would require the payment of a premium upon purchase of Bonds pursuant to
Section  5.02  unless  there shall have been  deposited  the full amount of such
premium in trust with the Trustee prior to any notification of a change pursuant
to  Section  4.01 or 4.02.  Payments  from such  trust  fund for the  payment of
premium  may be made  only  upon  receipt  by the  Trustee  of a  Non-Bankruptcy
Certificate from the Company.

                  6. It shall be a condition to any Change in the Interest  Rate
Mode on any Bonds of from one mode to another  mode that the Trustee  shall have
received written confirmation from each Rating Agency then rating the Bonds that
the ratings then assigned by such Rating Agency to the Bonds will not be reduced
or withdrawn by reason of such change in the Interest Rate Mode; provided that a
withdrawal of a short-term rating from any Bonds being converted to a Fixed Rate
shall not be  considered  to be a withdrawal  of a rating for such purpose if no
other  ratings  applicable  to  any  or all of the  Bonds  will  be  reduced  or
withdrawn.

unpaid  thereon to the  Redemption  Date;  provided that prior to requesting the
Trustee to give  notice of any such  redemption,  the  Authority  or the Company
shall have  delivered to the Trustee for  cancellation  on the  Redemption  Date

                  (d) During any  Auction  Rate-Inverse  Rate Period on or after
the  expiration of a no-call  period which shall commence on the expiration of a

preceding any Regular Interest Payment Date at a redemption price of:

                           (i) 104% of the principal  amount thereof if redeemed
         during the twelve month period ending one year after the  expiration of

Date,  as the case may be,  the  Market  Agent or, in the case of the Fixed Rate
Conversion  Date, the other investment bank or investment banks (selected by the
Company  and  approved  by the  Authority)  party to the Fixed  Rate  Commitment
certifies  to the Trustee,  Bond  Counsel and the  Authority in writing that the
foregoing schedule is not consistent with then-prevailing market conditions, the
Authority  at the  request  of the  Company  may revise  the  foregoing  Initial
Premium,  Reductions in Premium and No- Call Periods without the approval of the
Holders to reflect then-prevailing market conditions, upon receipt of an opinion
of Bond  Counsel to the effect that any  revisions  pursuant to this  paragraph,
either by itself  or in  conjunction  with the  establishment  of a  Calculation
Period or the Fixed Rate, as the case may be, are made in  accordance  with this
Indenture,  is  permitted  under  the Act and  will  not  adversely  affect  the
exclusion  of  interest on the Bonds from gross  income for  federal  income tax
purposes.

                  Any  optional   redemption   shall  be  conditioned  upon  the
Trustee's receipt of funds (or, in the case of any optional redemption occurring
while the Bonds bear  interest  at a Daily  Rate,  Weekly  Rate,  Monthly  Rate,
Semi-Annual Rate or Commercial Paper Rate,  Available Moneys)  sufficient to pay
the  redemption  price of the Bonds to be redeemed on or prior to the redemption
date.

                  SECTION 5.02. Tender for and Purchase upon Election of Holder.
1.  During  any Daily Rate  Period or Weekly  Rate  Period,  any Bond or portion
thereof in a principal  amount equal to an authorized  denomination  (so long as
the  principal  amount not  purchased is an  authorized  denomination)  shall be
purchased  on the demand of the Holder  thereof on any  Business  Day at a price
equal to the principal amount thereof plus accrued interest, if any, to the date
of  purchase,  upon  delivery to the  Registrar  and Paying Agent and the Market
Agent at their  respective  principal  offices,  by the close of business on any
Business  Day of a Notice  of  Election  to  Tender  in  substantially  the form
attached hereto as, or containing  substantially  the information  contained in,
Exhibit B; provided,  however,  that the substance of such Notice of Election to
Tender  must  also be  given  telephonically  to the  Market  Agent  prior to or
simultaneously with delivery of such written Notice of Election to Tender to the
Market Agent. The date on which such Bond shall be purchased shall,

at the request of the Holder  thereof  (i) if the Bond then bears  interest at a
Daily Rate, be the date of delivery of such Notice of Election to Tender if such
Notice of Election to Tender is delivered to the  Registrar and Paying Agent and
the Market  Agent by 10:00  a.m.(New  York City time) on such date or may be any
Business  Day  thereafter,  or (ii) if the Bond then bears  interest at a Weekly

                  2. During any Monthly Rate Period or  Semi-annual  Rate Period
on or prior to the Fixed Rate Conversion  Date, any Bond or portion thereof in a
principal  amount equal to an authorized  denomination (so long as the principal
amount not  purchased is an authorized  denomination)  shall be purchased on the
demand  of  the  Holder  thereof  on  the  first  Business  Day  following  each
Calculation  Period  at a price  equal to the  principal  amount  thereof,  upon
delivery  to the  Registrar  and  Paying  Agent and the Market  Agent,  at their
respective  principal offices of a Notice of Election to Tender in substantially
the  form  attached  hereto  as  or  containing  substantially  the  information
contained  in Exhibit B on or prior to a Business  Day which is not less than 10
days,  in the case of Bonds  bearing  interest at a  Semi-annual  Rate, or seven
days,  in the case of Bonds  bearing  interest at a Monthly  Rate,  prior to the
proposed date of purchase;  provided, however, that the substance of such Notice
of  Election  to Tender must also be given  telephonically  to the Market  Agent
prior to or  simultaneously  with delivery of such written Notice of Election to
Tender to the Market Agent.

Company,  the Market Agent, the Liquidity Facility Issuer and, upon request, the
Authority  by  telephone,  promptly  confirmed  in  writing,  of  such  receipt,
specifying the contents thereof.

                  4. Any Notice of Election to Tender shall be irrevocable. If a
Holder  fails to deliver the Bonds  referred to in such notice to the  Registrar
and Paying Agent, such Bonds shall nevertheless be deemed to have been purchased
on the date established for the purchase thereof,  and, to the extent that there
shall be on deposit in the Bond Purchase Fund on such date an amount  sufficient
to pay the principal amount thereof,  plus accrued interest, if any, no interest
shall  accrue on such Bonds from and after the date of purchase  and such Holder
shall have no rights hereunder  thereafter as the owner of such Bonds except the
right to receive the purchase price of such Bonds.

                    5. The right of a Holder  to tender a Bond to the  Registrar
               and Paying Agent shall  terminate after the Fixed Rate Conversion
               Date.

                  SECTION 5.03. Mandatory Tender for Purchase upon Change in the
Interest  Rate Mode on Business Day  Following  Certain  Calculation  Periods or

Rate,  Term Rate,  Commercial  Paper Rate,  Auction  Rate during an Auction Rate
Period, or Auction Rate and related Inverse Rate during an Auction Rate- Inverse
Rate Period shall be subject to mandatory tender for purchase in accordance with
the terms hereof, on the effective date of such Change in the Interest Rate Mode
at a price equal to the  principal  amount  thereof  plus  accrued  interest and
premium, if any, in accordance with Section 4.01.

                  2.  During  any Term Rate  Period  or  Commercial  Paper  Rate
Period,  the  Bonds  shall be  subject  to  mandatory  tender  for  purchase  in
accordance with the terms hereof on the Business Day immediately  following each
Calculation  Period,  each at a price equal to the principal amount thereof plus
accrued interest and premium, if any.

                  3. The Bonds  shall also be subject  to  mandatory  tender for
purchase in accordance  with the terms hereof on the Fixed Rate  Conversion Date
at a price equal to the  principal  amount  thereof  plus  accrued  interest and
premium, if any.

                  4. Notice of mandatory  tender for  purchase  upon a Change in
the  Interest  Rate  Mode  or upon a  conversion  to a Fixed  Rate  shall  be in
substantially  the  form  attached  hereto  as,  or  contain  substantially  the
information contained in, Exhibit A.

                  5. Any such notice of mandatory  tender for purchase  required
by  this  Section  5.03  shall  be  given  by the  Trustee,  in the  name of the
Authority,  or the Trustee  shall cause the  Registrar  and Paying Agent to give
such notice (with copies thereof to be given to the Market Agent,  the Registrar
and Paying Agent, the Bond Insurer,  the Company,  the Liquidity Facility Issuer
and any Rating  Agency  then  rating  the Bonds and in the case of Auction  Rate
Bonds during an Auction Rate Period,  or Auction  Rate-Inverse Rate Bonds during
an Auction  Rate-Inverse Rate Period, the Auction Agent, and, upon request,  the
Authority) by  first-class  mail to the Holders of the Bonds subject to purchase
at their addresses shown on the books of registry.

                    6. Bank  Bonds  are not  subject  to  mandatory  tender  for
               purchase pursuant to this
Section 5.03.

                  7.  Purchase  price of tendered  Bonds shall  include  premium
solely to the extent that (i) such Bonds bear interest at a Term Rate or Inverse
Rate and (ii) the applicable redemption price therefor would include the premium
specified  in Section 5.01 if such Bonds were to be  optionally  redeemed on the
date such Bonds are to be purchased.

                  SECTION 5.04.  Extraordinary  Optional Redemption.  During any
Term Rate Period,  Fixed Rate Period or Auction  Rate-Inverse  Rate Period,  the
Bonds are also subject to  redemption  prior to maturity in whole at any time at

notice  given as provided in the  Indenture,  except in the case of a redemption
pursuant to clause (iii) below,  at a  redemption  price equal to the  principal
amount thereof,  together with unpaid interest accrued thereon to the date fixed
for redemption, in any of the following events:

                           (i) All or  substantially  all of the  Project  shall
                  have been damaged or  destroyed or title to, or the  temporary
                  use of, all or a substantial portion of the Project shall have
                  been taken under the  exercise of the power of eminent  domain
                  by any governmental  authority, or person, firm or corporation
                  acting under governmental  authority,  as in each case renders
                  the Project  unsatisfactory  to the  Company for its  intended
                  use;

                           (ii)  Unreasonable  burdens or excessive  liabilities
                  shall have been imposed upon the Authority or the Company with
                  respect to all or substantially all of the Project,  including
                  without  limitation the imposition of federal,  state or other
                  ad  valorem  property,  income or other  taxes  other  than ad
                  valorem  taxes in effect on the date of  original  issuance of
                  the Bonds levied upon  privately  owned  property used for the
                  same general purpose as the Project, as well as any statute or
                  regulation  enacted or promulgated after the Closing Date that
                  prevents  the Company from  deducting  interest on the Company
                  Note for federal income tax purposes;

                           (iii) All or  substantially  all of the Project shall
                  be  transferred  or sold to any entity other than an affiliate
                  of the Company;  in the case of  redemption  under this clause
                  (iii) of Section 5.04, the redemption  price shall be equal to
                  101% of the  principal  amount  of the  Bonds,  together  with
                  unpaid  interest   accrued  thereon  to  the  date  fixed  for
                  redemption,  unless a smaller or no premium  would be due upon
                  optional  redemption of the Bonds pursuant to another  section
                  of the Indenture; or

                           (iv) Any court or regulatory or  administrative  body
                  shall enter or adopt,  or fail to enter or adopt,  a judgment,
                  order,  approval,  decree, rule or regulation,  as a result of
                  which  the  Company  elects  to  cease  operation  of  all  or
                  substantially all of the Project.

                  SECTION 5.05.  Redemption if  Participation  Agreement or Note
Void,  Unenforceable  or  Impossible  to Perform.  The Bonds shall be subject to
redemption  prior to their  Stated  Maturity  at any time on a Business  Day, in
whole but not in part, upon the receipt by the Trustee of a written  certificate
from the Company  given in  accordance  with  Section  6.3 of the  Participation
Agreement  stating that the Company  intends to prepay the amounts payable under
the  Participation  Agreement  and the  Note and  certifying  that,  within  the
preceding 120 days, a change in the Constitution of the State of New York or the
Constitution  of the United States of America or legislative  or  administrative
action  (whether  state or  federal) or final  decree,  judgment or order of any
court or  administrative  body  (whether  state or federal) has  occurred  which
results in the Participation Agreement or the Note or both of them becoming void
or  unenforceable  or impossible  to perform in  accordance  with the intent and
purpose of the parties as expressed in the Participation Agreement and the Note,
at a redemption  price equal to the  principal  amount  thereof plus accrued and
unpaid interest to the date fixed for redemption.

                                                        V-5

                  Any  redemption  under this Section 5.05 shall be  conditioned
upon the  Trustee's  receipt  of funds (or,  in the case of any such  redemption
occurring  while the Bonds bear interest at a Daily Rate,  Weekly Rate,  Monthly
Rate, Semi-Annual Rate or Commercial Paper Rate, Available Moneys) sufficient to
pay the  redemption  price  of the  Bonds  to be  redeemed  on or  prior  to the
redemption date.

                  SECTION 5.06. Special Tax Redemption Provisions.  1. The Bonds
shall be subject to mandatory  redemption  prior to their stated maturity (i) in
part,  at a redemption  price equal to the  principal  amount of the Bonds to be
redeemed,  plus accrued interest,  if any, to the date fixed for redemption,  if
such  partial  redemption  will  preserve  the  exclusion  from gross income for
federal  income tax  purposes  of interest on the  remaining  Bonds  outstanding
(provided,  however,  in the case of Auction  Rate-Inverse  Rate Bonds during an
Auction  Rate-Inverse Rate Period, the Authority shall redeem an equal aggregate
principal  amount of Auction  Rate Bonds and  Inverse  Rate  Bonds),  or (ii) in
whole, at a redemption price equal to the principal amount thereof, plus accrued
interest,  if any,  to the date  fixed for  redemption,  if, in a  published  or
private  ruling of the  Internal  Revenue  Service or in a final,  nonappealable
judicial  decision  by a court  of  competent  jurisdiction  (provided  that the
Company has been afforded the  opportunity  to participate at its own expense in
the proceeding  resulting in such ruling or in the litigation  resulting in such
decision,  as the case may be), it is determined  that, as a result of a failure
by the Company to observe any covenant,  agreement or  representation in the Tax
Regulatory Agreement,  interest on any Bond is includable for federal income tax
purposes in the gross income of the Holders  thereof  (other than a "substantial
user" of the Project or a "related  person" as provided in Section 147(a) of the
Code) (any such event constituting a "Determination of Taxability") and, in such
event, the Bonds shall be subject to such mandatory redemption on a Business Day
not more than 180 days after the giving of notice by the Trustee or a Bondholder
to the Authority and the Company of such published or private ruling or judicial
decision and  demanding  redemption  of the Bonds.  Either the  Authority or the
Company  shall  immediately  notify  the  Trustee  upon  learning  of  any  such
Determination  of Taxability.  The Trustee shall not be deemed to have knowledge
of such an event unless it has actual knowledge thereof.

                  2. During any  Semi-annual  Rate  Period,  Term Rate Period or
Fixed Rate Period,  the Bonds will also be subject to mandatory  redemption at a
redemption  price equal to the  principal  amount  thereof plus unpaid  interest
accrued thereon to the redemption date if the Company  reasonably  concludes and
certifies to the Trustee that the business, properties,  condition (financial or
otherwise),  operations or business  prospects of the Company will be materially
and  adversely  affected  unless the Company  takes or omits to take a specified
action and that the Company has been advised in writing by Bond Counsel that the
specified action or omission would cause the use of the Project to be such that,
pursuant to Section 150 of the Code, the Company would not be entitled to deduct
the  interest on the Company  Note for  purposes of  determining  the  Company's
Federal taxable income,  for a period of not less than sixty (60) consecutive or
nonconsecutive  days during a twenty-four  month  period.  Such  conclusion  and
certification  shall be  evidenced  by  delivery  to the  Trustee  of a  written
certificate  of an  Authorized  Company  Representative  to the effect  that the
Company  has  reached  such  conclusion,  together  with a  certified  copy of a
resolution of the Board of Directors of the Company authorizing such certificate
and a copy of such advice of Bond Counsel. In the event

                                                        V-6

<PAGE>



that the Bonds become subject to redemption as provided in this  paragraph,  the
Bonds will be  redeemed  in whole  unless  redemption  of a portion of the Bonds
outstanding would, in the opinion of Bond Counsel, have the result that interest
payable  on the  Company  Note for the Bonds  remaining  outstanding  after such
redemption  would be deductible for purposes of determining  the Federal taxable
income of the  Company,  and, in such event,  the Bonds to be redeemed  shall be
selected (in the principal  amount of $5,000 or any integral  multiple  thereof)
from time to time at random in such manner as the  Trustee  shall  determine  in
accordance with the Indenture, in such amount as is necessary to accomplish that
result.  The occurrence of an event  requiring the redemption of the Bonds under
this  paragraph  does not constitute an event of default under any Note or under
the Indenture and the sole  obligation in such event shall be for the Company to
prepay  the Note in an  amount  sufficient  to redeem  the  Bonds to the  extent
required by this paragraph.

                  SECTION 5.06-A.  Redemption of Bank Bonds. Any Bank Bonds held
by the  Liquidity  Facility  Issuer  shall be  redeemed  at the times and in the
principal amounts specified in the Liquidity  Facility.  Any redemption pursuant
to this Section  5.06-A shall be at a price equal to one hundred  percent (100%)
of the principal  amount of the Bonds so redeemed,  plus accrued interest at the
Bank Bond Interest Rate to the redemption date.

                  SECTION 5.07. Redemption at Demand of the State. In accordance
with the  provisions of Section 1864 of the Act, the State of New York may, upon
furnishing  sufficient funds therefor,  require the Authority to redeem prior to
maturity,  as a whole,  the  Bonds on any  Interest  Payment  Date not less than
twenty years after the Closing Date. The Authority  shall deposit any such funds
received by it with the Trustee. The Trustee shall deposit any such funds in the
Bond Fund and, upon notice  published in the manner  provided in Section 1864 of
the Act, shall apply such funds to the redemption of the Bonds,  at a redemption
price equal to lesser of (i) the optional  redemption price, if any,  applicable
on such date set forth in  Section  5.01 and (ii) 105% of the  principal  amount
thereof,  together, in either case, with accrued and unpaid interest, if any, to
the date fixed for  redemption,  all in the manner  provided in this  Article V.
Upon such redemption and notwithstanding anything to the contrary in Article XV,
the Trustee shall assign the Note relating to the Bonds to or as directed by the
Authority.

                  SECTION 5.08. Mandatory Tender for Purchase Upon Expiration or
Termination of any Liquidity  Facility.  1. Except as otherwise set forth in the
last sentence of this  subsection  1, on the date of  expiration or  termination
(including  a date of  termination  evidenced  by receipt by the Trustee and the
Registrar  and Paying  Agent of a written  notice  from the  Liquidity  Facility
Issuer or any other person authorized to deliver a notice in accordance with the
Liquidity  Facility of an event which permits or mandates the termination of the
Liquidity  Facility  under the terms  thereof  and any  termination  arising  in
connection with the delivery of an Alternate Liquidity Facility which results in
the  withdrawal  or  reduction  of any  rating  applicable  to the Bonds) of any
Liquidity  Facility  (or on the next  preceding  Business  Day,  if such date of
expiration or  termination is not a Business Day), the Bonds shall be subject to
mandatory purchase at a price equal to the principal amount thereof unless on or
prior to the 35th  day  prior to such  date of  expiration  or  termination  the
Company on behalf of the Authority has furnished to the Trustee (a) an extension
of such Liquidity Facility, or

                                                        V-7

(b) an Alternate  Liquidity Facility with another bank or financial  institution
providing  an  Alternate  Liquidity  Facility  in  replacement  of the  expiring
Liquidity  Facility  together with the  confirmation  of ratings  referred to in
Section 6.02(1).  No tender for purchase of any Bonds shall be required pursuant
to this Section 5.08 during an Auction Rate Period,  or an Auction  Rate-Inverse
Rate Period or if the Fixed Rate  Conversion  Date shall have occurred on a date
prior to such date of expiration.

                  2. Notice of the  mandatory  tender for  purchase  pursuant to
this  Section  5.08  shall be given  on or  prior  to the  30th day  before  the
expiration or termination  date  (including a date of  termination  evidenced by
receipt by the Trustee and the Registrar and Paying Agent of a written notice of
an event of default under a Liquidity  Facility) of a Liquidity  Facility by the
Trustee  in  the  name  of the  Authority  (with  copies  thereof  given  to the
Authority,  the Market Agent, the issuer of the expiring Liquidity Facility, the
Company,  the Bond  Insurer,  any Rating  Agency  then  rating the Bonds and the
Registrar  and Paying  Agent) by  first-class  mail to the  Holders of the Bonds
subject to mandatory  tender for purchase at their  addresses shown on the books
of registry.  Such notice shall be in substantially the form attached hereto as,
or contain substantially the information contained in, Exhibit C.

                    3. Bank  Bonds or Bonds  held by or for the  account  of the
               Company are not subject to mandatory tender for purchase pursuant
               to this Section 5.08.

                  SECTION 5.09. General  Provisions  Applicable to Mandatory and
Optional  Tenders  for  Purchase of Bonds.  1. If interest  has been paid on the
Bonds, or an amount sufficient to pay interest thereon has been deposited in the
Bond Fund, or an amount sufficient to pay accrued interest thereon,  if any, has
been set aside in the Bond  Purchase  Fund held  under the Bond  Purchase  Trust
Agreement,  and the purchase  price equal to the principal  of, and premium,  if
any, on the Bonds shall be available in the Bond  Purchase  Fund for purchase of
Bonds subject to tender for purchase pursuant to Section 5.02, 5.03 or 5.08, and
if any Holder  fails to deliver or does not  properly  deliver  the Bonds to the
Registrar  and Paying  Agent for which a Notice of  Election  to Tender has been
properly  filed or which are  subject to  mandatory  tender for  purchase on the
purchase date therefor,  such Bonds shall  nevertheless  be deemed  tendered and
purchased on the date  established for the purchase  thereof,  no interest shall
accrue on such Bonds from and after the date of purchase and such former Holders
shall have no rights  hereunder as the registered  owners of such Bonds,  except
the right to receive the purchase price of and interest to the purchase date, if
any, on such Bonds upon  delivery  thereof to the  Registrar and Paying Agent in
accordance  with  the  provisions  hereof.  The  purchaser  of  any  such  Bonds
remarketed by the Market Agent, or any Support  Facility  Issuer,  to the extent
Bonds are  purchased  with the  proceeds of a draw on, or  borrowing  or payment
under,  the Support  Facility,  shall be treated as the registered owner thereof
for all purposes of the  Indenture.  If the  ownership of the Bonds is no longer
maintained in book-entry form by the Securities  Depository the payment of Bonds
pursuant  to  Section  5.02  shall be  subject  to  delivery  of such Bonds duly
endorsed  in blank for  transfer or  accompanied  by an  instrument  of transfer
thereof in form satisfactory to the Registrar and Paying Agent executed in blank
for transfer at the  principal  office of the  Registrar  and Paying Agent at or
prior to 10:00 a.m.  (11:30 a.m. for Bonds  bearing  interest at the Weekly Rate
and 12:00 noon, for Bonds bearing interest at the Daily Rate) (New York City

time),  on a specified  purchase date. The Registrar and Paying Agent may refuse
to make  payment with  respect to any Bonds  tendered  for purchase  pursuant to
Sections 5.02,  5.03 or 5.08 not endorsed in blank or for which an instrument of
transfer satisfactory to the Registrar and Paying Agent has not been provided.

                  2. The purchase  price of Bonds subject to tender for purchase
pursuant to Section 5.02,  5.03 or 5.08 in an aggregate  principal  amount of at
least one million dollars ($1,000,000) shall be payable in immediately available
funds or by wire transfer upon written notice from the Holder thereof containing
the wire transfer  address (which shall be in the continental  United States) to
which such Holder wishes to have such wire  directed,  if such written notice is
received by the  Registrar and Paying Agent not less than five days prior to the
related purchase date.

                  3. To the extent that a  Liquidity  Facility is required to be
in effect,  Bonds  tendered for purchase may not be purchased by the  Authority,
the Company or any Affiliate  from the Market Agent upon a remarketing  of Bonds
pursuant to the Market Agent Agreement.

                  SECTION 5.10. Selection of Bonds to be Redeemed.  1. Except as
provided  otherwise in  subsections  2, 3, 4 and 5 below with respect to Auction
Rate-Inverse Rate Bonds during an Auction Rate-Inverse Rate Period, a redemption
of Bonds shall be a redemption of the whole or of any part of the Bonds from any
funds  available  for that purpose in a principal  amount equal to an authorized
denomination  (so long as the  principal  amount not  redeemed is an  authorized
denomination). If less than all Bonds shall be redeemed, the particular Bonds to
be redeemed  shall be chosen by the  Trustee,  or the Trustee  shall  direct the
Registrar and Paying Agent to so choose, as hereinafter  provided.  If less than
all the Bonds  shall be  called  for  redemption  under  any  provision  of this
Indenture  permitting such partial redemption,  the particular Bonds or portions
of Bonds to be redeemed shall be selected (a) first, from Bonds held or owned by
or for any Support Facility Issuer pursuant to any Support Facility, (b) second,
from Bonds for which the Registrar and Paying Agent has received,  prior to such
selection,  a Notice of Election to Tender  requiring  the  Registrar and Paying
Agent to purchase  such Bonds on the date on which the Bonds being  selected are
to be redeemed and (c) third, from all other Bonds then  Outstanding,  by lot or
on a pro rata basis by the  Trustee  or,  upon  direction  of the  Trustee,  the
Registrar  and Paying  Agent,  in such  manner as the Trustee or  Registrar  and
Paying Agent in its  discretion  may deem proper;  provided,  however,  that the
portion of any Bond to be redeemed shall be in the principal  amount of $100,000
or some integral multiple thereof during a Commercial Paper Rate Period, a Daily
Rate  Period,  a Weekly Rate Period or a Monthly  Rate  Period,  $25,000 or some
integral  multiple  thereof  during an Auction  Rate  Period,  or $5,000 or some
integral  multiple  thereof at any other time and that,  in selecting  Bonds for
redemption,  the Trustee or Registrar  and Paying Agent shall treat each Bond as
representing  that number of Bonds which is obtained by dividing  the  principal
amount of such  registered  Bond in  excess of  $100,000  by  $100,000  during a
Commercial  Paper Rate Period,  a Daily Rate  Period,  a Weekly Rate Period or a
Monthly Rate Period,  $25,000  during an Auction Rate Period,  and $5,000 at any
other time (such amounts being hereinafter  referred to as the "applicable units
of principal amount").  If it is determined that one or more, but not all of the
$100,000,  $25,000 or $5,000 units of principal  amount  represented by any such
Bond is to be called for redemption,

                                                        V-9

<PAGE>



then upon notice of intention to redeem such $100,000, $25,000 or $5,000 unit or
units,  the Holders of such Bonds shall  forthwith  surrender  such Bonds to the
Registrar and Paying Agent for (1) payment of the  redemption  price  (including
the  redemption  premium,  if any,  and accrued and unpaid  interest to the date
fixed for  redemption)  of the  $100,000,  $25,000  or  $5,000  unit or units of
principal  amount called for redemption and (2) exchange for a new Bond or Bonds
of the aggregate  principal amount of the unredeemed balance of the principal of
such  Bonds.  If the  Holders of any such Bond of a  denomination  greater  than
$100,000, $25,000 or $5,000 shall fail to present such Bond to the Registrar and
Paying  Agent,  for  payment  and  exchange  as  aforesaid,   such  Bond  shall,
nevertheless,  become due and  payable on the date fixed for  redemption  to the
extent of the  $100,000,  $25,000 or $5,000  unit or units of  principal  amount
called for redemption (and to that extent only).

                  2.  Auction  Rate  Bonds and  Inverse  Rate  Bonds  during any
Auction  Rate-Inverse Rate Period shall be redeemed in minimum  denominations of
$25,000 or integral multiples  thereof.  So long as the ownership of the Auction
Rate Bonds and  Inverse  Rate  Bonds is  maintained  in book-  entry form by the
Securities Depository, the Trustee shall give the Securities Depository at least
two Business  Days notice of the record date selected by it for the purpose of a
redemption  (each  a  "Redemption  Record  Date")  and  request  the  Securities
Depository  to  provide  it with a  position  listing  showing  at the  close of
business as of such Redemption  Record Date the aggregate  principal amounts of:
Regular  Auction Rate Bonds,  Special  Auction Rate Bonds,  Regular Inverse Rate
Bonds,  Regular  Linked  Auction  Rate Bonds and Inverse  Rate Bonds and Special
Linked Auction Rate Bonds and Inverse Rate Bonds, respectively.

                  3. So long as the  ownership of the Auction Rate Bonds and the
Inverse Rate Bonds during any Auction  Rate-Inverse Rate Period is maintained in
book-entry form by the Securities Depository, the Auction Rate Bonds and Inverse
Rate Bonds to be  redeemed in part on any  Redemption  Date shall be selected by
lot from the  Outstanding  Bonds of each series as  described  in the  following
sentence.  An amount equal to the Linked  Percentage of the aggregate  principal
amount of the Auction  Rate Bonds and Inverse  Rate Bonds to be redeemed on such
Redemption  Date shall be selected  from Regular  Linked  Auction Rate Bonds and
Inverse Rate Bonds and Special  Linked Auction Rate Bonds and Inverse Rate Bonds
(on a pro rata basis in accordance with the relative principal amounts thereof),
the remaining amount of Inverse Rate Bonds to be redeemed shall be selected from
Regular Inverse Rate Bonds and the remaining  amount of Auction Rate Bonds to be
redeemed shall be selected from Regular  Auction Rate Bonds and Special  Auction
Rate  Bonds  (on a pro rata  basis in  accordance  with the  relative  principal
amounts  thereof);  provided,  that if any principal  amount of the Auction Rate
Bonds and of the Inverse  Rate Bonds  selected as  provided  above from  Regular
Linked  Auction Rate Bonds and Inverse Rate Bonds,  Special  Linked Auction Rate
Bonds and Inverse Rate Bonds,  Regular Inverse Rate Bonds,  Regular Auction Rate
Bonds and  Special  Auction  Rate Bonds is not equal to  $25,000 or an  integral
multiple thereof,  the Trustee shall, in such manner as, in its sole discretion,
it shall determine, round up or down the principal amounts so determined. On the
basis of the position  listing  obtained by the Trustee pursuant to subsection 2
above,  the Trustee shall  calculate the Linked  Percentage as of the Redemption
Record  Date and  determine  therefrom  the  aggregate  principal  amounts to be
redeemed  and  redemption  prices per $1,000 (plus  accrued and unpaid  interest
thereon to the Redemption Date) of Regular Auction Rate

Bonds,  Special Auction Rate Bonds,  Regular Inverse Rate Bonds,  Regular Linked
Auction Rate Bonds and Inverse Rate Bonds and Special  Linked Auction Rate Bonds
and Inverse Rate Bonds, respectively.

                  4. So long as the  ownership of the Auction Rate Bonds and the
Inverse  Rate  Bonds  is  maintained  in  book-entry   form  by  the  Securities
Depository,  Auction  Rate Bonds to be redeemed in part on any  Redemption  Date
pursuant  to  subsection  (c)(ii) of Section  5.01 shall be selected by lot from
Special Auction Rate Bonds and Regular Auction Rate Bonds on a pro rata basis in
accordance  with the relative  principal  amounts  thereof as of the  Redemption
Record Date;  provided,  that if any principal  amount of the Auction Rate Bonds
selected as provided above from Regular  Auction Rate Bonds and Special  Auction
Rate Bonds is not equal to $25,000 or an integral multiple thereof,  the Trustee
shall, in such manner as, in its sole discretion,  it shall determine,  round up
or down the  principal  amounts  so  determined.  On the  basis of the  position
listing  obtained by the Trustee  pursuant to  subsection  2 above,  the Trustee
shall  determine  therefrom the aggregate  principal  amounts to be redeemed and
aggregate  redemption  prices (plus accrued and unpaid  interest  thereon to the
Redemption  Date) of Regular  Auction Rate Bonds and Special Auction Rate Bonds,
respectively.

                  5. Except as otherwise  provided by subsections 3 and 4 above,
redemption  of Auction  Rate Bonds and  Inverse  Rate Bonds  during any  Auction
Rate-Inverse Rate Period shall be in the manner specified in 1 above;  provided,
however,  that the portion of any Auction Rate Bonds or Inverse Rate Bonds to be
redeemed shall be in the principal  amount of $25,000 or some integral  multiple
of $25,000.

                  SECTION 5.11.  Notice of  Redemption.  1. Notice of redemption
shall be given by the  Trustee or the  Registrar  and Paying  Agent by mailing a
copy of the redemption notice by first- class mail at least 30 days prior to the
date fixed for redemption to the Bond Insurer and the Holders of the Bonds to be
redeemed at the  addresses  shown on the  registration  books  maintained by the
Registrar  and  Paying  Agent;  provided,   however,  with  respect  to  Auction
Rate-Inverse  Rate Bonds during an Auction  Rate-Inverse Rate Period such notice
shall be given  after the  Regular  Interest  Payment  Date next  preceding  the
Redemption Date but not less than thirty (30) days prior to the Redemption Date.

                  2. The  Registrar  and Paying  Agent  shall not be required to
transfer  or  exchange  Bonds  during any  period  beginning  at the  opening of
business  fifteen (15) days before the day of mailing of a notice of  redemption
and ending at the close of business on the day fixed for  redemption;  provided,
however, that the foregoing shall not apply during a Daily Rate Period, a Weekly
Rate  Period,  a  Commercial  Paper Rate  Period,  an Auction  Rate Period or an
Auction Rate- Inverse Rate Period.

                    3.  Except as  otherwise  provided  with  respect to Auction
               Rate-Inverse  Rate Bonds in  subsection  4 below,  each notice of
               redemption  shall  state:  (i) the full title of the  Bonds,  the
               redemption date, the place of redemption and the redemption price
               payable upon such redemption;

                                                       V-11

(ii) that the interest on the Bonds,  or on the principal  amount  thereof to be
redeemed,  shall cease to accrue from and after such redemption  date; and (iii)
that on said date there will become due and  payable on the Bonds the  principal
amount thereof to be redeemed and the interest  accrued on such principal amount
to the redemption date, if any, and the premium, if any, thereon. Each notice of
redemption  mailed to the  Holder of the Bonds  shall,  if less than the  entire
principal sum thereof is to be redeemed, also state the principal amount thereof
and the distinctive numbers of the Bonds to be redeemed and that such Bonds must
be  surrendered to the Registrar and Paying Agent in exchange for the payment of
the  principal  amount  thereof to be  redeemed  and the  issuance of a new Bond
equalling  in  principal  amount  that  portion of the  principal  sum not to be
redeemed  of the Bonds to be  surrendered.  The  failure  to give  notice to any
Holder of a Bond or any defects in such notice shall not affect the  proceedings
for the redemption of the Bonds for which notice has been given.

                  4. With  respect  to Auction  Rate-Inverse  Rate  Bonds,  each
notice of redemption  shall (i) specify (A) in the case of a partial  redemption
of Inverse Rate Bonds and Auction Rate Bonds, the aggregate principal amounts of
Regular  Auction Rate Bonds,  Special  Auction Rate Bonds,  Regular Inverse Rate
Bonds,  Regular  Linked  Auction  Rate Bonds and Inverse  Rate Bonds and Special
Linked Auction Rate Bonds and Inverse Rate Bonds to be redeemed, (B) in the case
of a partial  redemption of Auction Rate Bonds, the aggregate  principal amounts
of Regular Auction Rate Bonds and Special Auction Rate Bonds to be redeemed, (C)
the Redemption  Date, (D) the redemption price per $1,000 principal amount (plus
accrued and unpaid interest  thereon to the Redemption  Date) of Regular Auction
Rate Bonds,  Special  Auction Rate Bonds,  Regular  Inverse Rate Bonds,  Regular
Linked Auction Rate Bonds and Inverse Rate Bonds and Special Linked Auction Rate
Bonds and Inverse  Rate Bonds,  respectively,  and (E) the place or places where
amounts  due upon such  redemption  will be  payable  and (ii) state that on the
Redemption  Date, if sufficient  moneys are available for such  redemption,  the
Bonds or the  portions  thereof  which are to be  redeemed  shall  cease to bear
interest.

                  5. In the case of any optional  redemption  or any  redemption
pursuant  to Section  5.05,  such notice  shall also state that such  redemption
shall be conditioned upon the Trustee's receipt of funds (or, in the case of any
optional  redemption  occurring  while the Bonds bear  interest at a Daily Rate,
Weekly Rate, Monthly Rate,  Semi-annual Rate or Commercial Paper Rate, Available
Moneys) sufficient to pay the redemption price of the Bonds to be redeemed on or
prior to the redemption date.

                  6. Failure to give any required notice of redemption as to any
particular  Bonds will not affect the validity of the call for redemption of any
Bonds in respect to which no such failure  occurs.  Notice of  redemption  shall
also be mailed by  first-class  mail to the Credit  Facility  Issuer and to each
Rating  Agency then rating the Bonds,  which notice shall  include the principal
amounts, maturities and CUSIP numbers of Bonds to be redeemed. Any notice mailed
as provided in this  Section  shall be  conclusively  presumed to have been duly
given,  whether or not the Registered  Owner,  the Credit  Facility  Issuer or a
Rating Agency actually receives the notice.

                  SECTION 5.12.  Bonds Purchased by Liquidity  Facility  Issuer.
Bonds  subject to purchase  pursuant to  Sections  5.02,  5.03 and 5.08 shall be
deemed purchased by the Liquidity Facility Issuer in a principal amount equal to
the amount of a draw on, or borrowing or payment under,  the Liquidity  Facility
for the payment of Bonds subject to purchase,  upon the deposit with the Trustee
of the proceeds of such draw on, or borrowing or payment  under,  the  Liquidity
Facility  in an amount  equal to the  principal  of such Bonds plus  accrued and
unpaid  interest  thereon to the  redemption  date,  and such Bonds shall not be
deemed paid and shall remain outstanding  hereunder until the Liquidity Facility
Issuer has been  reimbursed for such draws on, or borrowings or payments  under,
the Liquidity  Facility to pay such principal and interest.  Any Bonds purchased
by the Liquidity Facility Issuer shall become Bank Bonds, shall bear interest at
the Bank Bond Interest Rate and shall be subject to the terms and provisions of,
and have all rights with respect to Bank Bonds under,  the applicable  Liquidity
Facility.  In the event that the  Liquidity  Facility  is in a form other than a
standby bond  purchase  agreement,  unless the Liquidity  Facility  Issuer shall
otherwise direct,  any Bonds purchased by the Liquidity Facility Issuer shall be
immediately  registered in the name of the Liquidity Facility Issuer as a Holder
and the  Liquidity  Facility  Issuer  shall have all rights of a Holder of Bonds
except that such Bonds will bear interest at the Bank Rate under this Indenture.

                  SECTION  5.13.  Effect of  Redemption.  If the Bonds have been
duly called for redemption  and notice of the  redemption  thereof has been duly
given or provided for as hereinbefore  provided and if monies for the payment of
the Bonds (or of the principal  amount  thereof to be redeemed) and the interest
to  accrue to the  redemption  date on the  Bonds  (or of the  principal  amount
thereof to be redeemed),  if any, and the premium,  if any, thereon are held for
the purpose of such  payment by the  Trustee,  then the Bonds (or the  principal
amount thereof to be redeemed)  shall on the redemption  date designated in such
notice,  become due and  payable  and  interest  on the Bonds (or the  principal
amount  thereof to be redeemed) so called for  redemption  shall cease to accrue
from such date and the Holder thereof shall  thereafter have no rights hereunder
as the Holder of such Bonds (or the  principal  amount  thereof to be  redeemed)
except to receive the principal  amount thereof and premium (if any) thereon and
interest to the redemption date.

                    SECTION  5.14.  Cancellation  of Redeemed  Bonds.  Any Bonds
               surrendered  or  redeemed  pursuant  to the  provisions  of  this
               Article shall be cancelled by the Registrar and Paying Agent.

                                                    ARTICLE VI

                                            SUPPORT FACILITY PROVISIONS

                  SECTION  6.01.  Support  Facility - General.  Pursuant  to the
Participation  Agreement,  the Company has obtained a Credit Facility and agrees
to maintain a Liquidity  Facility meeting the requirements of the  Participation
Agreement  with respect to the Bonds at all times except during any Auction Rate
Period,  an  Auction  Rate-Inverse  Rate  Period or the  Fixed  Rate  Period.  A
Liquidity Facility relating to the affected Bonds must be in effect prior to any
Change in the Interest Rate Mode from an Auction Rate and a related Inverse Rate
during an Auction  Rate-Inverse  Rate Period,  or from an Auction Rate during an
Auction  Rate  Period to another  Adjustable  Rate  (other  than a Change in the
Interest  Rate Mode to an Auction  Rate Period or an Auction  Rate-Inverse  Rate
Period or a conversion  to a Fixed Rate).  If at any time the Company  obtains a
Liquidity  Facility with respect to the Bonds which were previously not entitled
to the benefit  thereof,  the Company  shall submit such  Liquidity  Facility to
Moody's,  S&P or such  other  Rating  Agency as the  Company  may select for the
purposes of obtaining a rating on such Bonds. Upon obtaining a rating or ratings
on the basis of such Liquidity Facility the provisions of Sections 5.08 and 6.02
shall become  applicable to such Bonds.  The Trustee  shall be furnished  with a
certified copy of any Liquidity  Facility obtained pursuant to this Section 6.01
together  with  evidence  of any  rating  or  ratings  obtained  on the Bonds in
connection therewith.

                  Any  Support  Facility  Issuer  not  located in New York State
shall provide the Trustee with a list of holidays on which it is closed  through
the next  succeeding  January  1 at the  beginning  of the term of such  Support
Facility and by January 1 of each year thereafter.

                  SECTION 6.02. Liquidity Facility. 1. At any time following the
Closing Date, the Company with the consent of the Bond Insurer,  may provide for
the  delivery  to the  Trustee  of a  Liquidity  Facility  that is  issued  by a
financial institution with a long term debt rating of at least A from S&P and A2
from Moody's and that supports  ratings at least the  equivalent of A-1 from S&P
and P-1 from Moody's.  The expiration date of such Liquidity Facility shall be a
date not  earlier  than 364 days from its date of  issuance,  subject to earlier
termination  upon the occurrence of (a) a Terminating  Event or another event of
default  under  the  related  reimbursement  agreement  or  other  corresponding
agreement  pursuant to which such Liquidity Facility is issued, (b) the issuance
of an Alternate Liquidity Facility, (c) payment in full of the Outstanding Bonds
or (d) a Change in the  Interest  Rate Mode to an Auction Rate during an Auction
Rate  Period,  an  Auction  Rate and a related  Inverse  Rate  during an Auction
Rate-Inverse  Rate Period,  or a Fixed Rate. If, between the effective date of a
Liquidity  Facility and the effective date of an Alternate  Liquidity  Facility,
there  occurs a Change in the  Interest  Rate  Mode,  such  Alternate  Liquidity
Facility shall comply with the requirements  applicable to a Liquidity  Facility
in effect with respect to the new Interest Rate Mode. On or prior to the date of
the delivery of a Liquidity  Facility or an  amendment  to a Liquidity  Facility
(other than an amendment  which only extends the expiration  date of an existing
Liquidity  Facility) (a  "Liquidity  Facility  Amendment")  to the Trustee,  the
Company shall furnish to the Trustee and the

                                                       VI-1

Bond Insurer on behalf of the Authority  (a) an opinion of Bond Counsel  stating
that the delivery of such Liquidity  Facility or Liquidity Facility Amendment to
the Trustee is  authorized  under this  Indenture  and  complies  with the terms
hereof,  (b) written  confirmation from S&P, if the Bonds are then rated by S&P,
and from  Moody's,  if the Bonds are then  rated by  Moody's,  and from  another
rating agency,  if the Bonds are then rated by such rating agency, to the effect
that such rating agency has reviewed the proposed  Alternate  Liquidity Facility
or  Liquidity  Facility  Amendment  and that the  substitution  of the  proposed
Alternate Liquidity Facility for the existing Liquidity Facility or the delivery
of the Liquidity Facility  Amendment will not, by itself,  result in a reduction
or withdrawal of its long- or short-term rating of the Bonds below the rating of
S&P or Moody's or such other rating  agency,  as the case may be, then in effect
with respect to the Bonds,  and (c) written  consent of the Bond Insurer to such
Liquidity Facility or Liquidity Facility Amendment.

                  2. In the  event  that  the  Company,  delivers  an  Alternate
Liquidity  Facility  in  substitution  for a  Liquidity  Facility or a Liquidity
Facility  Amendment  which will result in a reduction  in or  withdrawal  of the
short-term or long-term  rating or both assigned to such Bonds by Moody's or S&P
or such other rating agency as a result of the Alternate  Liquidity  Facility or
Liquidity  Facility  Amendment,  all Outstanding Bonds (unless the Bonds bear an
Auction  Rate  during an Auction  Rate  Period,  Auction  Rate during an Auction
Rate-Inverse Rate Period or Fixed Rate) shall be subject to mandatory tender for
purchase  pursuant to Section  5.08.  It shall be a condition to the delivery of
such an Alternate  Liquidity  Facility or Liquidity  Facility Amendment that (i)
the Opinion of Bond Counsel  referred to in the preceding  paragraph be obtained
and (ii)  the  prior  written  consent  of the Bond  Insurer  be  obtained.  The
Authority,  or the Company on behalf of the  Authority,  shall deliver notice to
the  Trustee of the  substitution  of an  Alternate  Liquidity  Facility  or the
delivery of a Liquidity  Facility  Amendment which will result in a reduction or
withdrawal in the short-term or long-term ratings assigned to the Bonds pursuant
to this  Section  6.02 at  least 45 days  before  the  date of  substitution  or
amendment.

                  3. In the event that any Liquidity Facility Issuer (other than
a  municipal  bond or  financial  guarantee  insurance  company)  should fail to
maintain short-term ratings equivalent to A-1 from S&P and P-1 from Moody's, and
such Liquidity  Facility Issuer is not replaced within 4 months, all Bonds shall
be subject to mandatory tender for purchase pursuant to Section 5.08. No Bond so
tendered shall be remarketed unless and until an Alternate Liquidity Facility is
delivered  to the Trustee  and a prior  written  consent of the Bond  Insurer is
obtained.

                  SECTION  6.03.  Trustee not  Responsible  for  Enforcement  of
Support  Facility.  Except as may otherwise be expressly  agreed by the Trustee,
the Trustee shall have no responsibility  with respect to the enforcement of any
Support Facility obtained hereunder.

                    SECTION  6.04.  Payments  Pursuant  to  the  Municipal  Bond
               Insurance Policy. 1. As long as a Policy shall be in effect,  the
               Trustee  shall,  at least one day prior to each Interest  Payment
               Date,  determine  whether there will be  sufficient  funds in the
               Bond Fund to pay the  principal  of or  interest  on the Bonds on
               such Interest  Payment Date or on the date on which the Bonds are
               subject to redemption  pursuant to Section 5.06.1. If the Trustee
               determines that there will be insufficient

                                                       VI-2

<PAGE>



funds in the Bond  Fund,  the  Trustee  shall so notify the Bond  Insurer.  Such
notice  shall  specify the amount of the  anticipated  deficiency,  the Bonds to
which such  deficiency is applicable and whether such Bonds will be deficient as
to principal or interest,  or both.  If the Trustee has not so notified the Bond
Insurer at least one day prior to an Interest  Payment  Date,  the Bond  Insurer
will make  payments of  principal  or interest due on the Bonds on or before the
first  Business Day next following the date on which the Bond Insurer shall have
received notice of nonpayment from the Trustee.

                  2. The Trustee  shall after giving  notice to the Bond Insurer
as provided in  paragraph 1 of this  Section  6.04,  make  available to the Bond
Insurer and, at the Bond Insurers direction,  to the United States Trust Company
of New  York,  as  insurance  trustee  for the  Bond  Insurer  or any  successor
insurance  trustee (the  "Insurance  Trustee"),  the  registration  books of the
Authority maintained by the Trustee and all records relating to the Bond Fund.

                  3. The  Trustee  shall  provide  to the Bond  Insurer  and the
Insurance  Trustee a list of registered  owners of the Bonds entitled to receive
principal  or interest  payments  from the Bond  Insurer  under the terms of the
Policy,  and shall make  arrangements  with the  Insurance  Trustee  (i) to mail
checks or drafts to the registered  owners of the Bonds entitled to receive full
or partial  interest  payments  from the Bond Insurer and (ii) to pay  principal
upon Bonds  surrendered  to the Insurance  Trustee by the  registered  owners of
Bonds  entitled  to receive  full or partial  principal  payments  from the Bond
Insurer.

                  4. The Trustee  shall,  at the time it provides  notice to the
Bond Insurer  pursuant to paragraph 1 of this Section  6.04,  notify  registered
owners of Bonds entitled to receive the payment of principal or interest thereon
from the Bond Insurer (i) as to the fact of such entitlement, (ii) that the Bond
Insurer  will remit to them all or a part of the interest  payments  next coming
due upon proof of the Bondholders  entitlement to interest payments and delivery
to the Insurance Trustee,  in form satisfactory to the Insurance Trustee,  of an
appropriate  assignment of the registered  owner's right to payment,  (iii) that
should they be  entitled  to receive  full  payment of  principal  from the Bond
Insurer,  they must surrender their Bonds (along with appropriate  instrument of
assignment in form  satisfactory to the Insurance Trustee to permit ownership of
such Bonds to be  registered in the name of the Bond Insurer) for payment to the
Insurance Trustee, and not the Trustee, and (iv) that should they be entitled to
receive partial payment of principal from the Bond Insurer,  they must surrender
their Bonds for payment  thereon  first to the  Trustee,  who shall note on such
Bonds the portion of the principal  paid by the Trustee and then,  along with an
appropriate  instrument  of  assignment  in form  satisfactory  to the insurance
trustee,  to the Insurance  Trustee,  which will then pay the unpaid  portion of
principal.

                  5. In the event that the  Trustee  has notice that any payment
of  principal  of or  interest  on a Bond which has become Due for  Payment  (as
defined in the  Policy)  and which is made to a Holder of a Bond by or on behalf
of the  Authority  has  been  deemed a  preferential  transfer  and  theretofore
recovered  from its registered  owner  pursuant to the United States  Bankruptcy
Code by a trustee in  bankruptcy  in  accordance  with the final,  nonappealable
order of a court having competent  jurisdiction,  the Trustee shall, at the time
the Bond insurer is notified pursuant to paragraph 1 of this

                                                       VI-3

<PAGE>



Section 6.04,  notify all registered  owners of the Bonds that in the event that
any registered  owner's payment is so recovered,  such registered  owner will be
entitled  to payment  from the Bond  Insurer to the extent of such  recovery  if
sufficient funds are not otherwise  available,  and the Trustee shall furnish to
the Bond  Insurer its  records  evidencing  the  payments  of  principal  of and
interest  on the Bonds  which  have been made by the  Trustee  and  subsequently
recovered  from  registered  owners of the  Bonds  and the  dates on which  such
payments were made.

                  6. In addition  to those  rights  granted to the Bond  Insurer
under this Indenture,  the Bond Insurer shall, to the extent it makes payment of
principal  of or  interest  on Bonds,  become  subrogated  to the  rights of the
recipients of such payments in accordance  with the terms of the Policy,  and to
evidence such  subrogation  (i) in the case of subrogation as to claims for past
due interest,  the Trustee shall note the Bond  Insurer's  rights as subrogee on
the  registration  books  upon  receipt  from the Bond  Insurer  of proof of the
payment of interest  thereon to the registered  owners of the Bonds, and (ii) in
the case of subrogation  as to claims for past due principal,  the Trustee shall
note the Bond  Insurer's  rights as  subrogee  on the  registration  books  upon
surrender of the Bonds by the registered  owners thereof  together with proof of
the payment of principal thereof.

                  SECTION 6.05 Provisions with Respect to the Bond Insurer. With
respect to any  Bonds,  the  payment of which is insured by the Bond  Insurer in
accordance  with the terms of the Policy,  notwithstanding  anything else to the
contrary herein, the following additional provisions shall apply:

                  (a) A copy of any notice given by the Authority or the Company
under this Indenture to the Holders of the Bonds shall also be given to the Bond
Insurer.

                  (b) The Trustee  shall  notify the Bond Insurer of any failure
of the Authority or the Company to provide a notice to the Bond Insurer pursuant
to any provision of this Indenture.

                  (c) Notwithstanding any other provision of this Indenture, the
Trustee  shall  immediately  notify the Bond Insurer upon the  occurrence  of an
Event of Default.

                  (d) Any  action  under this  Indenture  that is subject to the
prior  consent of the  Holders  of the Bonds  shall also be subject to the prior
written consent of the Bond Insurer.

                  (e) Notwithstanding any other provision of this Indenture,  in
determining  whether  the rights of the  Holders of the Bonds will be  adversely
affected  by any  action  taken  pursuant  to the terms and  provisions  of this
Indenture,  the Trustee shall consider the effect on the Holders of the Bonds as
if there were no Municipal Bond Insurance Policy.

                  (f) To the  extent  this  Indenture  confers  upon or gives or
grants to the Bond Insurer any right, remedy or claim under or by reason of this
Indenture,  the  Bond  Insurer  is  hereby  explicitly  recognized  as  being  a
third-party beneficiary hereunder, and notwithstanding anything to the contrary

                                                       VI-4

contained  in this  Indenture  may  enforce  any  such  right  remedy  or  claim
conferred, given or granted hereunder.

                  (g)  Notwithstanding  any other  provision in this  Indenture,
upon the  occurrence and  continuance  of an Event of Default,  the Bond Insurer
shall be  entitled  to  control  and direct  the  enforcement  of all rights and
remedies  granted to the  Holders of the Bonds or the Trustee for the benefit of
the Holders of the Bonds under this Indenture, including without the limitation:
(i) the right to control  and direct the  declaration  of the  principal  of and
accrued  interest  on all the  Bonds  then  Outstanding  to be due  and  payable
immediately  pursuant to Section 12.03,  and (ii) the right to rescind and annul
any such  declaration  in  clause  (i) of this  paragraph  and its  consequences
pursuant to Section 12.03; provided, however, that the Bond Insurer shall not be
entitled to control and direct the  enforcement  of any such rights and remedies
if the Bond  Insurer is in default  under the Policy or if the Bond Insurer is a
party to any proceeding for the  rehabilitation,  liquidation,  conservation  or
dissolution of the Bond Insurer pursuant to the U.S.  Bankruptcy Code or similar
provision of law.

                  (h) The Trustee  shall  permit the Bond Insurer to have access

reasonable time.

                  (i) Any reorganization or liquidation plan with respect to the
Company  must  be  acceptable  to  the  Bond  Insurer.   In  the  event  of  any
reorganization or liquidation,  the Bond Insurer shall have the right to vote on
behalf of all Holders of the Bonds  absent a default by the Bond  Insurer  under
the Policy.

                  SECTION  6.06.  Payments  Pursuant to any Direct Pay Facility;
Condition to Delivery of Direct Pay  Facility.  The Trustee  shall draw upon any
Direct-Pay  Facility,  from time to time,  to the extent that it may do so under
the  terms  of  such  Direct-Pay  Facility.   The  Trustee  shall  apply  moneys
constituting  Available  Moneys  pursuant  to clause  (i),  (iii) or (iv) of the
definition  thereof as and to the extent  necessary to pay the  principal of (or
premium,  if any), and accrued  interest on, the Bonds, as the same shall become
due and payable either at maturity, upon redemption, by declaration or otherwise
(provided that moneys paid to the Trustee under any Direct-Pay  Facility  shall,
to the extent so specified in such Direct-Pay  Facility,  be applied only to the
payment of  particular  payments of  principal  of (or  premium,  if any on), or
accrued  interest on, the Bonds).  The Trustee  shall apply moneys  constituting
Available Moneys pursuant to clause (i) or (to the extent permitted by the terms
of any  Direct-Pay  Facility  then in effect) or clause (iii) of the  definition
thereof  as and to the  extent  necessary  to pay the  purchase  price  of Bonds
tendered or deemed  tendered to the Registrar  and Paying Agent  pursuant to the
Bond  Purchase  Trust  Agreement  (but only after  application  of  proceeds  of
remarketing  as provided in Section  2.03  thereof) as the same shall become due
and payable in accordance with this Indenture.  Notwithstanding anything in this
Indenture to the contrary, it shall be a condition to the delivery of any Direct
Pay Facility to the Trustee that (i) the Trustee and the Bond Insurer shall have
received from each Rating Agency then rating the Bonds written  confirmation  to
the effect that such Rating  Agency has  reviewed  such Direct Pay  Facility and

of any rating then  assigned to the Bonds and (ii) the Bond  Insurer  shall have
consented to the delivery of such Direct Pay Facility.

                                       GENERAL TERMS AND PROVISIONS OF BONDS

                  SECTION 7.01. Execution and Authentication of Bonds. The Bonds
shall be  executed  on  behalf  of the  Authority  by the  manual  or  facsimile
signature of its Chair,  Vice-Chair,  President or Treasurer and shall be sealed
with the seal of the  Authority,  or in lieu thereof shall bear a  lithographed,
engraved or otherwise  reproduced  facsimile of such seal attested by the manual
or facsimile signature of its Secretary or an Assistant Secretary.

                   Bonds  bearing  the manual  signature  of the  officer of the
Authority  authorized to execute such Bonds in office on the date of such manual
signing thereof and Bonds bearing the facsimile  signature of the officer of the
Authority  authorized  to  execute  such  Bonds  in  office  on the  date of the
reproducing  of such  facsimile  signature  on such  Bonds,  shall be valid  and
binding obligations in accordance with their terms,  notwithstanding that before
the delivery  thereof and payment  therefor the person whose  signature  appears
thereon shall have ceased to be such officer.

                  Only  Bonds  having   endorsed   thereon  a   certificate   of
authentication substantially in the form set forth in Article XVI, duly executed
by the  Registrar  and Paying  Agent,  shall be entitled to any right or benefit
under this  Indenture.  No Bonds  shall be valid or  obligatory  for any purpose
unless  and  until  such  certificate  of  authentication  shall  have been duly
executed  by the  Registrar  and  Paying  Agent,  and  such  certificate  of the
Registrar  and Paying Agent upon a Bond shall be  conclusive  evidence that such
Bond has been duly authenticated and delivered under this Indenture and that the
Holder thereof is entitled to the benefits of this Indenture.  The Registrar and
Paying Agent's certificate of authentication on any Bond shall be deemed to have
been duly  executed  if signed by an  authorized  officer of the  Registrar  and
Paying Agent.

                  SECTION  7.02.  Books of Registry.  The  Registrar  and Paying
Agent  shall  keep or cause to be kept at its  principal  office  books  (herein
referred  to as the  "books  of  registry"  or  "registration  books")  for  the
registration  and  transfer of the Bonds.  Upon  presentation  at its  principal
office for such purpose the Registrar and Paying  Agent,  under such  reasonable
regulations  as it may  prescribe,  shall  register or transfer,  or cause to be
registered or transferred,  on said books of registry,  the Bonds as hereinafter
set forth.  The books of registry  shall at all times during  business  hours be
open for  inspection  by the  Authority,  the Company,  the Bond Insurer and the
Trustee or their duly authorized agents or representatives.

                  SECTION 7.03.  Transfer,  Registration  and Exchange of Bonds.
The  transfer  of the Bonds may be  registered  only upon the books of  registry
required  to be kept  pursuant  to Section  7.02 upon  surrender  thereof to the
Registrar  and Paying Agent,  together  with an assignment  duly executed by the
Holder  thereof  or  his or her  duly  authorized  agent  and  accompanied  by a
guarantee  of  signature,  each in such  form as  shall be  satisfactory  to the
Registrar and Paying Agent. Upon any such registration of transfer the Authority
shall execute and the Registrar and Paying Agent shall

                                                       VII-1

<PAGE>



authenticate  and deliver in exchange  for such Bonds a new Bond or Bonds of the
same subseries,  if any, registered in the name of the transferee or transferees
for a like aggregate  principal  amount,  of any  denomination or  denominations
authorized by this  Indenture.  No transfer of any Bond shall be effective until
entered on the books of registry.

                  Any Bond  surrendered  in any such  registration  of  transfer
shall  forthwith be  cancelled  by the  Registrar  and Paying  Agent.  Any Bonds
registered  and  transferred  to a new Holder  pursuant to this Section shall be
delivered  to the Holder at the  principal  office of the  Registrar  and Paying
Agent or sent by first-class mail to the Holder at his or her request,  risk and
expense.

                  Bonds, upon surrender thereof at the principal corporate trust
office of the  Registrar and Paying  Agent,  together  with an  assignment  duly
executed  by the  Holder or his or her  authorized  agent and  accompanied  by a
guarantee  of  signature,  each in such  form as  shall be  satisfactory  to the
Registrar  and  Paying  Agent,  may,  at the option of the  Holder  thereof,  be
exchanged  for an  equal  aggregate  principal  amount  of  Bonds  of  the  same
subseries,  if any, of any  denomination  or  denominations  authorized  by this
Indenture and in the same form as the Bonds surrendered for exchange.  All Bonds
so surrendered  pursuant to this Section shall be cancelled by the Registrar and
Paying Agent.

                  Any Bonds to be delivered to the Holder upon any such exchange
shall be delivered to the Holder at the  principal  office of the  Registrar and
Paying  Agent or sent by  first-class  mail to the Holder  thereof at his or her
request, risk and expense.

                  Any taxes or other  governmental  charges  required to be paid
with respect to the  registration  of transfer or exchange of the Bonds shall be
paid by the Holder  requesting  registration of such transfer or exchange,  as a
condition  precedent to the  exercise of such  privilege.  The  Authority or the
Registrar  and  Paying  Agent,  or  both,  may  charge  the  Company  for  every
registration of transfer or exchange  sufficient to reimburse it for any and all
costs required to be paid in respect thereof.

                  SECTION 7.04. Mutilated,  Lost, Stolen, or Destroyed Bonds. In
the event any Bond shall be lost,  stolen,  destroyed,  wholly or in part, or so
defaced as to impair its value to the Holder,  the  Registrar  and Paying  Agent
shall, upon compliance with the terms provided by law,  authenticate and deliver
a new Bond of like series or  subseries,  if any,  date and tenor in exchange or
replacement  therefor  against delivery for cancellation of such mutilated Bond,
or in lieu of and in replacement  of a destroyed,  stolen or lost Bond, and upon
payment by the Holder of the  reasonable  expenses of the  Registrar  and Paying
Agent and the Authority and the  reasonable  charges of the Registrar and Paying
Agent in  connection  therewith  and,  in the event that the Bond is  destroyed,
stolen or lost,  the  Holder's  filing with the  Registrar  and Paying  Agent of
evidence satisfactory to it that the Bond was destroyed,  stolen or lost, of the
Holder's ownership  thereof,  and furnishing the Registrar and Paying Agent, the
Bond Insurer and the Authority such security and indemnity as is satisfactory to
them which shall name the  Authority as an  additional  secured and  indemnified
party.  Any  replacement  Bond issued  under the  provisions  of this Section in
exchange or substitution for the defaced,

                                                       VII-2

<PAGE>



mutilated or partly destroyed Bond or in  substitution,  for the allegedly lost,
stolen or wholly  destroyed  Bond shall be  entitled to the  identical  benefits
under this Indenture as was the original Bond in lieu of which such  replacement
Bond is issued.  Each such  replacement  Bond shall be prepared in substantially
the same manner as the original.

                  Notwithstanding  the foregoing  provisions of this Section, if
the lost,  stolen,  destroyed,  defaced or  mutilated  Bond has  matured or been
called for redemption and the date fixed for redemption thereof has arrived,  at
the option of the Registrar and Paying Agent,  payment of the amount due thereon
may be made  without the issuance of any  replacement  Bond upon receipt of like
evidence,  indemnity,  security  and payment of expenses and the  surrender  for
cancellation of the defaced or mutilated or partly  destroyed Bond and upon such
other conditions as the Registrar and Paying Agent may prescribe.

                  Except as provided in this  sentence  and as  permitted in the
following paragraph, any replacement Bond shall be in the form of the Bond being
replaced,  and be dated the date of its  authentication  and bear such number as
shall be assigned thereto by the Registrar and Paying Agent,  which number shall
have the  letters  "AR"  prefixed  thereto  together  with such other  subseries
designation,  if any, as may be deemed  appropriate  by the Registrar and Paying
Agent. The Registrar and Paying Agent shall make an appropriate  notation in the
books of  registry  that a  replacement  Bond has been  issued  in  exchange  or
substitution  for the  defaced,  mutilated,  lost,  stolen,  or wholly or partly
destroyed Bond.

                  There may be  imprinted  or  affixed on the face and the panel
portion of any  duplicate  Bond a mark to  identify  such Bond as a  replacement
Bond.

                  Prior  to  arranging  for the  preparation  or  printing  of a
replacement  Bond,  the  Registrar and Paying Agent may require a deposit by the
Holder to secure the  Registrar and Paying Agent and the Authority for costs and
expenses incurred by them in the preparation,  printing,  execution and issuance
of such  replacement  Bond. Any amount of such deposit received by the Registrar
and Paying Agent in excess of the amount required to reimburse the Registrar and
Paying Agent or the  Authority  for costs and expenses  shall be returned to the
party which made the deposit.

                  Any defaced, mutilated or partly destroyed Bond surrendered to
the Registrar and Paying Agent in  substitution  for a new Bond pursuant to this
Section shall be cancelled by the Registrar and Paying Agent.

                  SECTION 7.05.  Temporary  Bonds.  Pending the  preparation  of
definitive  Bonds,  interim  receipts  or  certificates  (herein  referred to as
"temporary  Bonds") may initially be issued,  exchangeable  for definitive Bonds
when the latter are ready for  delivery.  Such  temporary  Bonds may be printed,
lithographed or typewritten,  shall be of such  denomination or denominations as
may be determined by the Authority and may contain such references to any of the
provisions  of this  Indenture as may be  appropriate.  If  temporary  Bonds are
issued, the Authority will cause to be furnished duly executed  definitive Bonds
without delay, and thereupon the temporary Bonds may

                                                       VII-3

<PAGE>



be surrendered  for  cancellation  at the principal  office of the Registrar and
Paying  Agent in  exchange  for  definitive  Bonds and  without  charge for such
exchange,  and the Registrar and Paying Agent shall deliver in exchange for such
temporary Bonds so surrendered an equal aggregate principal amount of definitive
duly executed  Bonds,  of  authorized  denominations.  Until so  exchanged,  the
temporary  Bonds shall be entitled to the same benefits  under this Indenture as
definitive Bonds.

                  Nothing in this  Indenture  shall prevent the  Authority  from
delivering,  and the Authority is hereby expressly permitted to deliver, Auction
Rate Bonds  during an Auction  Rate  Period or Auction  Rate-Inverse  Rate Bonds
during an Auction Rate-Inverse Rate Period in typewritten form to the Securities
Depository as registered owner thereof.

                  SECTION 7.06.  Disposition of Bonds.  Any Bond  surrendered to
the Registrar and Paying Agent for payment shall be cancelled  upon such payment
by the Registrar and Paying Agent.  The Registrar and Paying Agent shall destroy
any  cancelled  Bond which has been paid and which  bears any date two (2) years
prior to the date of  destruction.  The Bonds  shall be  destroyed  by  burning,
machine shredding,  chemical  disintegration or such other method as is approved
by the Authority. The Authority may require that such destruction be done in the
presence of its appointee. When the Registrar and Paying Agent shall destroy any
Bond, it shall deliver a certificate of such  destruction to the Authority,  the
Bond Insurer and the Company.

                  SECTION 8.01.  Project  Fund.  1. There is hereby  created and
established a special trust fund to be designated  "KeySpan  Generation LLC 1999
Series A Project  Fund"  (hereinafter  referred to as the "Project  Fund") to be
held by the Trustee.  All income or gain on monies deposited in the Project Fund
shall be retained therein.

                  2. There shall be deposited into the Project Fund the proceeds
of the  Bonds  issued  hereunder,  net of  underwriter's  discount  and  accrued
interest, if any, which, pursuant to Section 2.02.6 of this Indenture,  is to be
used and  applied  together  with other  moneys  advanced  by the Company to the
prepayment of the KeySpan Notes, the proceeds of which prepayment are to be used
to pay the redemption price of the Prior Bonds. The accrued interest, if any, on
the Bonds shall be deposited in the Interest Account of the Bond Fund.

                  3. The monies on deposit from time to time in the Project Fund
shall be held  under  this  Indenture,  but shall not be  subject  to the liens,
pledges,  charges,  assignments  and trusts  created hereby for the security and
benefit of the Holders of the Bonds and shall not be  available  for the payment
of Bonds  within the  meaning of the  Indenture,  and shall be used and  applied
solely for the purpose of financing  the  prepayment of the KeySpan Notes and in
accordance with the remaining provisions of this Section and any excess shall be
used for the cost of issuance of the Bonds.

                  4. The Trustee is  authorized  and  directed to make  payments
from the Project Fund which together with moneys advanced by the Company will be
sufficient  to pay the  principal  amount  and  interest  payment  due under the
KeySpan Notes (the "Prepayment Price") or costs incurred in connection therewith
and the  refunding of the Prior Bonds,  upon the order of the Company,  but only
upon receipt from time to time of requisitions  signed by an Authorized  Company
Representative, stating with respect to each payment to be made from the Project
Fund:

                           (a) the requisition number;

                           (b) the nature of the disbursement;

                    (c) the payee, with address, which may be the Company in the

               Company;

                           (d) the amount of such payment;

                           (e) that  the  disbursement  will be used to pay,  or
                  reimburse  the Company for,  part of the  Prepayment  Price or
                  costs  incurred  in  connection  with  the  prepayment  of the
                  KeySpan Notes and the redemption of the Prior Bonds; and

                                                      VIII-1

<PAGE>



                           (f)  that  the  disbursement  will  not be  used in a
                  manner that would result in a violation of any  representation
                  or any covenant  contained in Section 5.4 of the Participation
                  Agreement  or be contrary to any  material  representation  or
                  warranty contained in the Tax Regulatory Agreement.

                  5. For seven years from the dates  thereof,  the Trustee shall
retain in its possession  all  requisitions  received by it as herein  required,
subject to the inspection of the Authority, its agents and representatives,  the
Company,  the Bond  Insurer  and the Holders  and their  representatives  at all
reasonable times at the Principal Corporate Trust Office.

                  6. All monies  remaining in the Project Fund after the payment
or provision for payment of the Prepayment  Price and all other costs to be paid
from such  Project  Fund shall,  at the written  direction  of the  Company,  be
deposited  in the Bond Fund for credit to the  Redemption  Account to be applied
solely in accordance with and subject to the restrictions contained in Article V
and Article IX hereof to the payment of principal  of and  premium,  if any, and
interest on the Bonds;  except for amounts  retained in the Project  Fund by the
Trustee with the approval of the appropriate  Authorized Company  Representative
for payment of items  permitted  to be financed  from such Fund but not then due
and payable,  any balance  remaining of such retained  funds in the Project Fund
after full payment or provision of payment of part of the Prepayment Price shall
be paid to the Trustee for deposit in the Bond Fund for credit to the Redemption
Account  and  applied by the  Trustee as  described  above.  At such time as all
monies have been paid from the Project Fund, the Trustee shall close the Project
Fund and thereupon all of its right,  title and interest  hereunder shall cease,
determine  and become void and the  Trustee  shall  execute  such  documents  to
evidence such release as may reasonably be required.

                  At such time as the Company elects to obtain,  and there is in
effect,  a Credit Facility in the form of a letter of credit,  and to the extent
necessary  to obtain or  maintain  the rating or ratings on the Bonds  resulting

                           (I) On the date such monies are received, amounts, if
         any, paid by the Company  pursuant to Section 4.3 of the  Participation
         Agreement or otherwise paid to the Trustee for such purpose;  provided,
         that prior to withdrawal  for the payment of interest,  such money must
         be on deposit under the Indenture for at least 124 days and that on the
         date such money is to be  applied to such  payment,  the  Company  must
         deliver a Non-Bankruptcy Certificate to the Trustee;

                           (II) On each Interest Payment Date, the proceeds of a

                           (III) On each Interest Payment Date, any other monies
         provided by the Company for such purpose.

Such  amounts  shall  otherwise  be  provided  solely  from the sources of funds
referred to in (III) above.

                  (iii) After the Fixed Rate Conversion Date, by 12:00 noon (New
York City time) on the Business Day next preceding each Interest Payment Date to
the Bond Fund for credit to the Interest Account the amount  required,  together

                  (b)(i)   During  an   Auction   Rate   Period  or  an  Auction

second  Business Day next  preceding  each Auction Date,  into the Bond Fund for
credit to the Redemption  Account an aggregate  amount of funds available on the
next Business Day in The City of New York equal to the aggregate amount required
to pay the principal of and premium, if any, and accrued interest on any Auction
Rate Bonds during an Auction Rate Period, or any Auction Rate-Inverse Rate Bonds
during an Auction  Rate-  Inverse  Rate Period,  as the case may be,  called for

Redemption  Account by the Company is not a Business  Day then the date for such
deposit to the Redemption Account by the Company shall be the first Business Day
immediately  preceding  the  scheduled  date of such  deposit to the  Redemption
Account by the Company. In the event such deposit is not made in accordance with
this paragraph (i), the Trustee shall immediately send a notice of such event to
the Auction Agent by telex,  telecopy or similar means.  If such deposit is made
by the Company  within 3 Business  Days of the second  Business Day  immediately

an Auction Rate Period or an Auction  Rate-Inverse  Rate  Period,  into the Bond
Fund for credit to the Redemption  Account the amount  required to pay principal
of and premium,  if any, and accrued and unpaid interest on any Bonds called for

                  At such time as the Company elects to obtain,  and there is in
effect,  a Credit  Facility  in the form of a letter of credit and to the extent
necessary  to obtain or  maintain  the rating or ratings on the Bonds  resulting
from such Credit Facility, amounts required to be deposited in the Bond Fund for
credit to the  Redemption  Account  shall be derived  solely from the  following
sources  of funds in the  priority  indicated  and  shall  be so  deposited  and
credited in the Redemption Account on the date indicated:

                           (I) On the date any redemption is scheduled to occur,
         Available Moneys, if any, on deposit in the Bond Fund;

                           (II) On the  date  any  redemption  is  scheduled  to
         occur,  the proceeds of a draw,  borrowing or payment  under the Credit
         Facility; and

                           (III) On the  date any  redemption  is  scheduled  to
         occur, any other monies provided by the Company for such purpose.

Such  amounts  shall  otherwise  be  provided  solely  from the sources of funds

available  therefor in said Redemption  Account,  to pay the redemption price of
the Bonds then being redeemed.

                    (c) On the date such  funds are  received,  into the  Rebate
               Fund,  the  amounts,  if any,  paid by the  Company  pursuant  to
               Section 7.3(H) of the Tax Regulatory Agreement in order to ensure
               compliance with Section 7.4 thereof.

                  Each installment of Note Payments shall be increased as may be
necessary to make up any previous deficiency in any of the required payments.

                  If  other  monies  are  received  by the  Trustee  as  advance
payments of Note Payments to be applied to the redemption of all or a portion of
the Bonds,  such monies  shall be  deposited  in the Bond Fund for credit to the
Redemption Account therein.

                  SECTION 9.03. Application of Monies in the Bond Fund. The Bond
Fund shall be used for the purpose of making scheduled  payments of principal of
and premium,  if any,  and  interest on the Bonds and of making  payments of the
redemption  price of Bonds then  subject  to  redemption  in the  manner  herein
provided. The monies in the Bond Fund shall be applied as follows:

                    (a)  Interest  Account.  On  or  prior  to  the  Fixed  Rate
               Conversion Date, on each Interest Payment Date, the Trustee shall
               apply the amount of monies then credited to the Interest  Account
               equal to the interest then payable on the Bonds to the payment of
               such interest on such Interest  Payment Date from funds described
               under Section 9.02(a)(ii),  or, in the case of Auction Rate Bonds
               during an Auction Rate Period or Auction  Rate-Inverse Rate Bonds
               during an Auction Rate- Inverse Rate Period,  as the case may be,
               from funds  described  under Section  9.02(a)(i).  In the event a
               Credit Facility in the form of a letter of credit is in place and
               payments  are  required  to be made  in the  order  specified  in
               Section 9.02  (a)(ii)(I),  (II) and (III) and if sufficient funds
               are  not  available  under  Section  9.02(a)(ii)(I)  to pay  such
               interest,  the Trustee shall request a draw, borrowing or payment
               under such Credit  Facility in accordance  with the terms thereof
               in an amount  equal to the  amount  required,  together  with the
               amounts, if any, available under Section  9.02(a)(ii)(I),  to pay
               the interest  payable on the  Outstanding  Bonds on such Interest
               Payment  Date and shall notify the Company of the amount and date
               of such  request.  If sufficient  funds are not  available  under
               Section 9.02(a)(ii)(I) and (II) to pay such interest, the Trustee
               shall  apply  funds,  if  any,   available  pursuant  to  Section
               9.02(a)(ii)(III),  to the extent  necessary,  to such  payment of
               interest.

                  (b)  Principal  Account.  If  the  Fixed  Rate  has  not  been
established prior to such date, on the Stated Maturity,  the Trustee shall apply
the  amount  of monies  then  credited  to the  Principal  Account  equal to the
principal  amount of Bonds then payable to the payment of such principal on such
date.  In the  event a Credit  Facility  in the form of a letter of credit is in
place and  payments  are  required to be made in the order  specified in Section
9.02(b) (ii) (I), (II) and (III) and if sufficient funds are not available under
Section 9.02(b)(ii)(I) to pay such principal,  the Trustee shall request a draw,
borrowing or payment  under such Credit  Facility in  accordance  with the terms
thereof in the amount  required,  together with the amounts,  if any,  available
under Section  9.02(b)(ii)(I)  to pay such principal amount and shall notify the
Company of the  amount and date of such  request.  If  sufficient  funds are not
available  under  Section  9.02(b)(ii)(I)  or (II) to pay  such  principal,  the
Trustee   shall   apply   funds,   if  any,   available   pursuant   to  Section
9.02(b)(ii)(III), to the extent necessary, to such payment.

                  (c) Redemption  Account.  The Trustee shall redeem on the date
set for the redemption  thereof,  as provided in Article V of this Indenture,  a
principal amount of Bonds then subject to redemption. The Trustee shall apply an
amount  credited to the  Redemption  Account equal to the  principal  amount and
premium,  if any, of Bonds then  subject to  redemption,  together  with accrued
interest  thereon to the  redemption  date,  to the payment of such Bonds on the
redemption date from funds described in Section 9.02(b).

                                                       IX-3

<PAGE>



                  All monies in the Redemption  Account on the last Business Day
prior to the Stated Maturity shall be transferred to the Principal Account.

                  On or prior to the Fixed Rate Conversion  Date, in the event a
Credit  Facility in the form of a letter of credit is in place and  payments are
required to be made in the order  specified in Section  9.02(b)(ii)  (I),(II) or
(III),  if  sufficient  amounts to make such  payment  are not  available  under
Sections  9.02(b)(ii)(I),  the  Trustee  shall  request a draw under such Credit
Facility in accordance with the terms thereof,  in an amount equal to the amount
required,   together   with   amounts,   if  any,   available   under   Sections
9.02(b)(ii)(I),  to pay the  principal  amount  of  Bonds  then to be  redeemed,
together with accrued  interest thereon to the date set for redemption and shall
notify the Company of the date and amount of such request. If sufficient amounts
to make such payment are not available under Section 9.02(b)(ii)(I) or (II), the
Trustee  shall  apply  amounts,  if any,  available  pursuant  to  Section  9.02
(b)(ii)(III), to the extent necessary, to such payment. Such redemption shall be
made pursuant to the provisions of Article V.

                  After the Fixed Rate  Conversion  Date, the Trustee shall make
all such redemption payments to the Holders in accordance with the terms of this
Indenture from funds described in Section 9.02(b)(iii).

                  Upon the  retirement of any portion of the Bonds by redemption
pursuant to the provisions of this Section 9.03, the Trustee shall file with the
Authority,  the Bond Insurer and the Company a statement  stating the amounts of
the Bonds so redeemed  and setting  forth the date of their  redemption  and the
amount  paid as  principal,  premium  and  interest  thereon.  The  expenses  in
connection  with the  redemption  of the Bonds  shall be paid by the  Company as
Additional Payments.

                  SECTION 9.04. Application of Monies in the Rebate Fund. 1. The
Rebate Fund and the amounts  deposited  therein  shall not be subject to a claim
and  charge in favor of the  Trustee  or any  Bondholders  and shall be  applied
solely in accordance  with the  provisions of the Tax  Regulatory  Agreement and
shall not be  available  for the  payment of Bonds  within  the  meaning of this
Indenture.  Amounts  deposited in the Rebate Fund shall be applied solely to pay
amounts  payable  to the  United  States  pursuant  to  Section  7.4 of the  Tax
Regulatory  Agreement in  accordance  with  subsection  (2) of this Section 9.04
except to the extent otherwise permitted by this Section 9.04.

                  2. In the  event  that on the  first  day of any Bond Year the
amount on deposit in the Rebate Fund  exceeds  the Rebate  Amount (as defined in
the Tax  Regulatory  Agreement),  the  Trustee,  upon  the  receipt  of  written
instructions from an Authorized Company Representative  specifying the amount of
such excess, shall withdraw such excess amount and deposit it in the Bond Fund.

                  Pending such  application,  such monies may be invested at the
direction  of an  Authorized  Company  Representative  in  accordance  with  the
provisions  of  Section  9.05;  provided  that  such  investment  will not be in
violation  of the  covenants  made to the  Authority  by the  Company in the Tax
Regulatory Agreement.

                  SECTION 9.05. Investment of Funds. Monies in the Bond Fund and
the  accounts  in such Bond Fund and in the Rebate  Fund shall be  invested  and
reinvested by the Trustee,  at the direction of the Company,  promptly confirmed
in  writing,  so long as the  Company is not in default  hereunder  or under the
Participation  Agreement, to the extent reasonable and practicable in Investment
Securities  selected by the Company and maturing in the amounts and at the times
as determined by the Company so that the payments  required to be made from such
funds and accounts may be made when due and  subsequent to the  occurrence of an
Event of Default  hereunder or under the  Participation  Agreement,  the Trustee
shall  invest  and  reinvest  monies  in the Bond  Fund and the  Rebate  Fund in
Investment  Securities maturing in such amounts and at such times as the Trustee
determines so that payment  required to be made from such funds may be made when
due.  Investment  earnings shall be considered on deposit in any Fund or Account
as of the date they are actually received by the Trustee.

                  Notwithstanding  the  foregoing,  Available  Moneys  or moneys
provided by the State of New York in accordance with Section 5.07 hereof held by
the Trustee or the  Registrar and Paying  Agent,  to the extent  permitted to be
invested,  shall be invested solely in direct  obligations  issued by the United
States of America  maturing  in such  amounts  and at such times as the  Trustee
determines so that payments  required to be made from such  Available  Moneys or
such moneys provided by the State of New York may be made when due.

                  Monies on deposit in the Project Fund and the accounts in such
Fund shall be invested and reinvested by the Trustee at the express direction of
the Company,  promptly  confirmed  in writing,  so long as the Company is not in
default  under  the  Participation  Agreement,  to  the  extent  reasonable  and
practicable, in Investment Securities maturing in such amounts and at such times
as it is  anticipated  by the  Company  that such  monies  together  with monies
advanced by the Company  will be  required  to pay the  redemption  price of the
Prior Bonds.

                  The  Company  may at any time and  from  time to time  deposit
Ineligible Moneys with the Trustee. Ineligible Moneys shall at all times be held
by the Trustee in the manner contemplated by clause (i) of the definition of the
term  "Available  Moneys" and  Available  Moneys shall at all times prior to the
application  thereof in accordance  with the terms hereof be held by the Trustee
in the manner contemplated by clause (i), (ii), (iii) or (iv) (as appropriate to
the source of such Available  Moneys) of the  definition of the term  "Available
Moneys".

                  The  Trustee,  with  the  consent  of the  Company,  shall  be
authorized to sell any investment when necessary to make the payments to be made
from the funds and accounts  therein.  All earnings on and income from monies in
said funds and  accounts  (other  than the  Project  Fund and the  Rebate  Fund)
created  hereby  shall be  considered  to be  Revenues  and shall be held in the
respective  account  in the Bond Fund for use and  application  as are all other
monies deposited in such accounts.  The Trustee shall, in the statement required
by Section 11.07,  set forth the Investment  Securities  held separately in, and
the earnings  realized on investment for, each fund and account  hereunder.  The
Trustee shall not be liable for any  depreciation in the value of the Investment
Securities  acquired  hereunder  or any loss  suffered  in  connection  with any
investment of funds made

by it in accordance herewith,  including,  without limitation, any loss suffered
in connection with the sale of any investment pursuant hereto.

                  The  Trustee  may make any such  investments  through  its own
investment department upon direction of the Company.

                  All  Investment  Securities  shall  constitute  a part  of the
respective  fund and accounts  therein from which the  investment  in Investment
Securities was made.

Indenture and any premium  required to be paid for the  retirement of said Bonds
by redemption,  at the places,  on the dates and in the manner specified in this
Indenture  and in said Bonds  according to the true intent and meaning  thereof,
subject, however, to the provisions of Section 2.02.3.

time to time execute and deliver such further  instruments and take such further
action as may be  reasonable  and as may be required to carry out the purpose of

pledge the credit of the  Authority or the State of New York or the taxing power
of the State of New York or otherwise be  inconsistent  with the  provisions  of
Section 2.02.3.

                  SECTION  10.04.  Inspection  of Project  Books.  All books and

the time of payment of any claims for interest on, any of the Bonds and will not
directly  or  indirectly  be a party  to or  approve  any  such  arrangement  by
purchasing  such claims for  interest or in any other  manner.  In case any such
claim for  interest  shall be  extended  in  violation  hereof,  such  claim for
interest shall not be entitled, in case of any default hereunder, to the benefit
or security of this Indenture except subject to the prior payment in full of the
principal  of,  and  premium,  if any,  on,  all Bonds  issued  and  outstanding
hereunder,  and of all claims for interest which shall not have been so extended
or funded.

any applicable sections of the Auction Agency Agreement.

                  SECTION  10.07.  Agreement  of  the  State  of  New  York.  In
accordance with the provisions of subdivision 11 of Section 1860 of the Act, the

with the  Bondholders  that the  State of New York  will not  limit or alter the
rights and powers vested by the Act in the Authority to fulfill the terms of any
contract made with Bondholders,  or in any way impair the rights and remedies of
such  Bondholders,  until the Bonds,  together  with the  premium,  if any,  and
interest  thereon,  with (to the extent permitted by law) interest on any unpaid
installments  of  interest,  and all costs and expenses in  connection  with any
action or  proceeding  by or on behalf  of such  Bondholders,  are fully met and
discharged.

                  SECTION   10.08.   Recording  and  Filing.   Pursuant  to  the
Participation  Agreement, the Company covenants that it will cause all financing
statements  related  to this  Indenture  and  all  supplements  thereto  and the
Participation  Agreement  and all  supplements  thereto,  as well as such  other
security agreements,  financing statements and all supplements thereto and other
instruments  as may be required from time to time to be kept, to be recorded and
filed in such  manner and in such places as may from time to time be required by
law in order to  preserve  and  protect  fully the  security  of Holders and the
rights of the  Trustee  hereunder,  and to take or cause to be taken any and all
other  action  necessary  to  perfect  the  security  interest  created  by this
Indenture.  The Company is obligated  under  Section  5.17 of the  Participation
Agreement to file all such financing statements and other security agreements.

                  SECTION 10.09.  Rights Under the  Participation  Agreement and
the Note. The Participation  Agreement, a duly executed counterpart of which has
been filed with the Trustee,  sets forth the  covenants and  obligations  of the

notices,  administrative compensation or indemnification under the Participation
Agreement.

                                         AUCTION AGENT AND INDEXING AGENT

                  SECTION  11.01.  Appointment of Trustee.  The Chase  Manhattan
Bank is hereby  appointed  the Trustee,  hereunder  and by the execution of this
Indenture  accepts such appointment and without further act, deed or conveyance,
shall be fully vested with all the estate,  properties,  rights, powers, trusts,
duties and obligations of the Trustee hereunder.

                  The Trustee shall set up suitable  accounts for the deposit of
the Note Payments and for the payment of the Bonds and the interest  thereon and
for all other  payments  provided  or  required  by this  Indenture,  including,
without limiting the generality of any of the foregoing, setting up of the Funds
created by Articles VIII and IX.

                  SECTION  11.02.  Indemnification  of Trustee as Condition  for
Remedial Action. The Trustee shall be under no obligation to institute any suit,
or to take any  remedial  proceeding  under  this  Indenture,  or to  enter  any
appearance  or in any way defend in any suit in which it may be made  defendant,
or to take any steps in the  execution  of the trusts  hereby  created or in the
enforcement of any rights and powers hereunder, until it shall be indemnified to
its  satisfaction  against any and all costs and  expenses,  outlays and counsel
fees and other reasonable disbursements,  and against all liability; the Trustee
may, nevertheless, begin suit, or appear in and defend suit, or do anything else
in its judgment proper to be done by it as such Trustee,  without indemnity, and
in such  case the  Trustee  shall be  reimbursed  from the  Additional  Payments
required to be made  pursuant to the  Participation  Agreement for all costs and
expenses,  outlays and counsel fees and other reasonable  disbursements incurred
in connection  therewith.  If the Company shall fail to make such reimbursement,
the Trustee may  reimburse  itself from any monies in its  possession  under the
provisions  of this  Indenture  and shall be entitled to a  preference  over the
Bonds;  provided,  however,  that the  proceeds of a Support  Facility  shall be
applied solely as set forth  elsewhere  herein and in such Support  Facility and
shall not be applied to the reimbursement set forth in this Section 11.02.

                  Notwithstanding  any other  provision of this Indenture or the
Bond  Purchase  Trust  Agreement,  no right of the Trustee or the  Registrar and
Paying Agent to  indemnification  shall relieve the Trustee or the Registrar and
Paying Agent from  responsibility  for (a) making payments on the Bonds when due
from moneys available to it, (b) accelerating the Bonds as required  pursuant to
Article XII, (c) drawing on the Liquidity  Facility in accordance  with the Bond
Purchase Trust Agreement,  (d) making any claim under the Credit Facility or (e)
sending notices of mandatory tenders of Bonds in accordance with this Indenture.

                    SECTION  11.03.  Trustee  Not  Liable  for  Failure  of  the
               Authority or Company to Act.  The Trustee  shall not be liable or
               responsible  because  of  the  failure  of the  Authority  or the
               Company

                                                       XI-1

or any of their  employees or agents to make any  collections  or deposits or to
perform any act herein  required of the  Authority or the  Company.  The Trustee
shall not be responsible for the application of any of the proceeds of the Bonds
or any other monies  deposited  with it and paid out,  withdrawn or  transferred
hereunder if such application,  payment, withdrawal or transfer shall be made in
accordance with the provisions of this Indenture.  The immunities and exemptions
from liability of the Trustee hereunder shall extend to its directors, officers,
employees and agents.

                    SECTION 11.04.  Certain Duties and  Responsibilities  of the
               Trustee. (a) Except during the continuance of an Event of Default
               specified in Section 12.01 of which the Trustee has been notified
               or is deemed to have notice as provided in Section 11.08,

                  (1) the Trustee  shall  undertake  to perform  such duties and
         only such duties as are specifically  set forth in this Indenture,  and
         no implied  covenants or obligations  shall be read into this Indenture
         against the Trustee; and

                  (2) in the  absence of bad faith on its part,  the Trustee may
         conclusively   rely,  as  to  the  truth  of  the  statements  and  the
         correctness of the opinions  expressed  therein,  upon  certificates or
         opinions furnished to the Trustee and conforming to the requirements of
         this  Indenture;  but in the case of any such  certificates or opinions
         which by any provision hereof are specifically required to be furnished
         to the Trustee,  the Trustee  shall be under a duty to examine the same
         to determine  whether or not they conform to the  requirements  of this
         Indenture.

                  (b) In case an Event of Default specified in Section 12.01 has
occurred and is  continuing  of which the Trustee has been notified or is deemed
to have notice as provided in Section 11.08,  the Trustee shall exercise such of
the rights and powers vested in it by this Indenture, and use the same degree of
care and skill in such  exercise,  as a prudent man would  exercise or use under
the circumstances in the conduct of his own affairs.

                  (c)  None  of  the  provisions  of  this  Indenture  shall  be
construed to relieve the Trustee from liability for negligent action,  negligent
failure to act, or willful misconduct, except that

                    (1) this  subsection (c) shall not be construed to limit the
               effect of subsection (a) of this Section;

                    (2)  the  Trustee  shall  not be  liable  for any  error  of
               judgment made in good faith by any one of its officers, unless it
               shall be proved that the Trustee was negligent;

                  (3) in the absence of bad faith on its part, the Trustee shall
         be protected and shall incur no liability in acting or proceeding or in
         not  acting  or not  proceeding  upon any  resolution,  order,  notice,
         telegram, request, consent, waiver, certificate,  statement, affidavit,
         voucher requisition,  bond or other paper or document which the Trustee
         shall  believe to be genuine and to have been  adopted or signed by the
         proper board or person or to have been

                                                       XI-2

         prepared  and  furnished  pursuant  to any of the  provisions  of  this
         Indenture,  or upon the  written  opinion  of any  attorney,  engineer,
         accountant  or other expert  believed by the Trustee to be qualified in
         relation to the subject matter,  and the Trustee shall be under no duty
         to make any investigation or inquiry as to any statements  contained or
         matters referred to in any such instrument but may accept and rely upon
         the same as  conclusive  evidence  of the  truth and  accuracy  of such
         statements;

                  (4) the Trustee shall not be liable with respect to any action
         taken or omitted to be taken by it in good faith in accordance with the
         direction  of the  Holders  of not less than a  majority  in  aggregate
         principal amount of the Outstanding  Bonds relating to the time, method
         and place of conducting any proceeding for any remedy  available to the
         Trustee,  or exercising any trust or power  conferred upon the Trustee,
         under the provisions of this Indenture; and

                  (5) no provision of this  Indenture  shall require the Trustee
         to  expend  or risk its own  funds or  otherwise  incur  any  financial
         liability  in  the  performance  of  its  duties  hereunder,  or in the
         exercise  of any of its rights or powers,  if it shall have  reasonable
         grounds  for  believing  that  repayment  of  such  funds  or  adequate
         indemnity  against such risk or liability is not reasonably  assured to
         it.

                  (d)  Notwithstanding  anything  contained  elsewhere  in  this
Indenture, the Trustee shall have the right to reasonably require, in respect of
the payment or withdrawal  of any monies or the taking of any action  whatsoever
within the purview of this  Indenture,  any  showings,  certificates,  opinions,
appraisals or other  information,  or corporate action or evidence  thereof,  in
addition to that  required by the terms  hereof as a condition of such action by
the Trustee.

                  (e) The Trustee may execute any of the trusts or powers hereof
and perform any of its duties by or through attorneys,  agents or receivers, and
the Trustee  shall not be  responsible  for any  negligence or misconduct on the
part of any such  attorney,  agent or  receiver  appointed  by it if the Trustee
shall have  exercised due care and  diligence in  appointing  or selecting  such
person,  and the Trustee shall be entitled to advice of counsel  concerning  all
matters of the trusts hereof and the duties hereunder,  and may in all cases pay
such reasonable compensation to all such attorneys,  agents and receivers as may
reasonably be employed in connection with the trusts hereof. The Trustee may act
upon the opinion or advice of any attorney or attorneys (who may be the attorney
or attorneys for the  Authority or the Company),  approved by the Trustee in the
exercise of reasonable  care, and the Trustee shall not be  responsible  for any
loss or damage  resulting from any action or nonaction in good faith in reliance
upon such opinion or advice.

                  (f)  Whenever  in the  administration  of this  Indenture  the
Trustee shall deem it desirable that a matter be proved or established  prior to
taking,  suffering or omitting any action  hereunder,  the Trustee (unless other
evidence be herein specifically  prescribed) may, in the absence of bad faith on
its part, rely upon a certificate of an Authorized Company  Representative or an
Authorized Officer.

                    (g) The Trustee shall not be accountable  for the use by the
               Company of any proceeds of the Bonds  authenticated  or delivered
               hereunder.

                    (h) The  Trustee  shall not be required to give any bonds or
               surety in  respect  of the  execution  of its  trusts  and powers
               hereunder.

insurance  or to  renew  any  policies  of  insurance  or to  inquire  as to the
sufficiency of any policies of insurance  carried by the Company,  or to report,
or make or file claims or proof of loss for, any loss or damage insured  against
or which may occur,  or to keep itself  informed or advised as to the payment of
any  taxes or  assessments,  or to  require  any such  payment  to be made.  The
Trustee,  except as to the  acceptance  of the trusts by its  execution  of this
Indenture and the performance of its responsibilities  hereunder,  shall have no
responsibility  in  respect  of the  validity,  sufficiency,  due  execution  or
acknowledgment of this Indenture,  or in respect of the validity of the Bonds or
the due execution or issuance thereof.  The Trustee shall be under no obligation
to see that any  duties  herein or in the  Participation  Agreement,  the Market
Agent Agreement,  the Auction Agency Agreement,  the Broker-Dealer  Agreement or
any Support  Facility  imposed  upon the  Authority,  the  Company,  any Support
Facility Issuer,  or any party other than itself in its capacity as Trustee,  or

capacity as Trustee to be performed, shall be done or performed, and the Trustee

covenants are so done or performed.

                  SECTION 11.06.  Compensation and  Indemnification  of Trustee.
The Company has agreed in the Participation  Agreement (1) to pay to the Trustee
from  time to time  reasonable  compensation  for all  services  rendered  by it
hereunder  (which  compensation  shall not be limited by any provision of law in
regard to the  compensation  of a trustee  of an express  trust);  (2) except as
otherwise  expressly  provided herein, to reimburse the Trustee upon its request
for all reasonable expenses,  disbursements and advances incurred or made by the
Trustee in  accordance  with any  provision  of this  Indenture  (including  the
reasonable  compensation  and the expenses and  disbursements  of its agents and
counsel),   except  any  such  expense,   disbursement  or  advance  as  may  be
attributable  to its  negligence or bad faith;  and (3) to indemnify the Trustee
for, and to hold it harmless  against,  any loss,  liability or expense incurred
without  negligence  or bad faith on its part,  arising out of or in  connection
with the  acceptance or  administration  of this trust,  including the costs and
expenses of defending  itself against any claim or liability in connection  with
the  exercise  or  performance  of any of its  powers or duties  hereunder.  The
Trustee  acknowledges  that it has no claim for  compensation,  reimbursement or
indemnity  from the proceeds of  remarketing of Bonds or from moneys drawn under
any Support Facility.

                  SECTION 11.07.  Statements from Trustee.  It shall be the duty

under this Indenture.

                  SECTION  11.10.  Trustee Not  Responsible  For  Recitals.  The
recitals, statements and representations contained herein and in the Bonds shall

Authority or the Company thereto or as to the validity,  sufficiency or adequacy
of the  security  afforded  thereby  or  hereby  or as to the  validity  of this
Indenture, the Note, the Participation Agreement, any Support Facility or of the
Bonds.

                  SECTION 11.11.  Qualification  of the Trustee.  There shall at
all times be a Trustee  hereunder  which shall be a bank and/or  trust  company,

authorized  to exercise  corporate  trust powers and subject to  examination  by
federal or state  authority.  The  Trustee  hereunder  shall not be  required to
maintain,  and any successor Trustee shall not be required to have, an office in
the city in which the  principal  office of the  initial  Trustee  hereunder  is
located.

                  If at any time the  Trustee  shall  cease  to be  eligible  in
accordance   with  the  provisions  of  this  Section  11.11,  it  shall  resign
immediately in the manner and with the effect specified in Section 11.12.

                  SECTION  11.12.  Resignation  and Removal of  Trustee.  (a) No
resignation or removal of the Trustee and no appointment of a successor  Trustee
pursuant  to this  Article  shall  become  effective  until  the  acceptance  of
appointment by the successor Trustee under Section 11.13.

                  (b) The  Trustee  may  resign  at any time by  giving  written
notice  thereof  to the  Authority,  the Bond  Insurer  and the  Company.  If an
instrument of acceptance by a successor Trustee shall not have been delivered to
the  Trustee  within  thirty  (30)  days  after  the  giving  of such  notice of
resignation,   the  retiring   Trustee  may  petition  any  court  of  competent
jurisdiction for the appointment of a successor Trustee.

                  (c) The  Trustee  may be  removed at any time by demand of the
Bond Insurer or the Holders of a majority in aggregate  principal  amount of the
Bonds then Outstanding,  signed in person by such Holders or by their attorneys,

                  (d)      If at any time:

                           (1) the  Trustee  shall  cease to be  eligible  under
         Section  11.11 and shall fail to resign  after  written  request by the
         Authority,  the Bond  Insurer or by a Holder who shall have been a bona
         fide Holder for at least six months, or

                           (2) the Trustee  shall become  incapable of acting or
         shall be adjudged a bankrupt or  insolvent or a receiver of the Trustee
         or of its property shall be appointed, or any public officer shall take
         charge or control of the Trustee or of its  property or affairs for the
         purpose of rehabilitation, conservation or liquidation,

                                                       XI-6

then, in either such case, (i) the Authority may remove,  and the Company or the
Bond  Insurer may request the  Authority  to remove,  the  Trustee,  or (ii) any
Holder who has been a bona fide Holder for at least six months may, on behalf of
herself  and all other  similarly  situated,  petition  any  court of  competent
jurisdiction for the removal of the Trustee and the appointment of a successor.

                  (e)  If  the  Trustee  shall  resign,  be  removed  or  become
incapable  of acting,  or if a vacancy  shall occur in the office of the Trustee
for any cause, the Authority shall promptly appoint a successor;  the Company or
the issuer of any Support Facility or both of them,  having the right to request
the appointment of a particular qualified institution as such successor.  Within
one year after such resignation,  removal or incapability,  or the occurrence of
such  vacancy,  a  successor  Trustee  may  be  appointed  by an  instrument  or
concurrent  instruments  in writing  executed  by the  Holders of a majority  in
principal  amount of the Bonds then  Outstanding  delivered to the Authority and
the  retiring  Trustee,  and,  upon such  delivery,  the  successor  Trustee  so
appointed shall,  forthwith upon its acceptance of such appointment,  become the
successor   Trustee  and  supersede  the  successor  Trustee  appointed  by  the
Authority.

                  (f) The Authority shall give notice to the Company, the Market
Agent, the Registrar and Paying Agent, the Auction Agent, any Rating Agency then
rating the Bonds,  the Bondholders  and the issuer of any Support  Facilities of
each  resignation  and each  removal  of a  Trustee  and each  appointment  of a
successor  Trustee  in the manner  set forth in  Section  17.03 with  respect to
Bondholders  and Section 17.09 with respect to the Company,  the Auction  Agent,
the Market Agent and any Rating Agency then rating the Bonds.  Each notice shall
include  the name and address of the  Principal  Corporate  Trust  Office of the
successor Trustee.

                  (g) The Trustee at any time other than during the  continuance
of an Event of Default  and for any reason  may be removed by an  instrument  in
writing,  executed  by an  Authorized  Officer of the  Authority,  appointing  a
successor, filed with the Trustee so removed.

                  SECTION 11.13.  Successor  Trustee.  Every  successor  Trustee
appointed  hereunder shall execute,  acknowledge and deliver to its predecessor,
and also to the  Authority and the Company,  an instrument in writing  accepting
such appointment  hereunder,  and thereupon such successor Trustee,  without any
further act, shall become fully vested with all the rights,  immunities,  powers
and trusts and subject to all the duties and  obligations,  of its  predecessor;
but such predecessor shall, nevertheless, on written request of its successor or
of the Authority and upon payment of expenses,  charges and other  disbursements
of such  predecessor  which are payable  pursuant to the  provisions of Sections
11.02  and  11.06,  execute  and  deliver  an  instrument  transferring  to such
successor  Trustee  all  the  rights,  immunities,  powers  and  trusts  of such
predecessor hereunder;  and every predecessor Trustee shall deliver all property
and monies held by it hereunder to its successor, subject,  nevertheless, to its
first lien and preference  provided for in Sections 11.02 and 11.06.  Should any
instrument in writing from the  Authority be required by any  successor  Trustee
for more fully vesting in such Trustee the rights, immunities, powers and trusts
hereby  vested or intended  to be vested in the  predecessor  Trustee,  any such
instrument in writing shall and will, on request, be executed,  acknowledged and
delivered by the Authority.

                  Upon the  occurrence  and during the  continuance of a Company
Downgrade  Event, the consent of the initial Bond Insurer shall be required with
respect to the  appointment of a successor  Trustee,  which consent shall not be
unreasonably withheld.

                  Notwithstanding  any  of  the  foregoing  provisions  of  this
Article,  any bank or trust  company  having  power to  perform  the  duties and
execute the trusts of this  Indenture and otherwise  qualified to act as Trustee
hereunder  with or into which the bank or trust company acting as Trustee may be
converted,  merged or  consolidated,  or to which the corporate  trust  business
assets as a whole or  substantially as a whole of such bank or trust company may
be sold, shall be deemed the successor of the Trustee.

                  SECTION 11.14.  Appointment of Market Agent. Goldman,  Sachs &
Co. is hereby appointed as the Market Agent for the Bonds to serve as such under
the terms and provisions  hereof and of the Market Agent  Agreement.  The Market
Agent, including any successor or successors appointed pursuant hereto, shall be

                  4. Upon the  occurrence  of a Failure  to  Deposit,  or in the
event such failure to deposit is cured, the Trustee shall give the Auction Agent
the notices referred to in Section 9.02(a)(i) or (b)(i), as the case may be.

                  SECTION  12.03.  Declaration of Principal and Interest As Due.
Upon the  occurrence  and  continuation  of any  Event of  Default  of which the
Trustee  has been  notified  or is deemed to have  notice as provided in Section
11.08,  then and in every  case  the  Trustee  by a  notice  in  writing  to the
Authority,  the Company and (to addresses  then  specified by the Authority) the
Governor, the Comptroller and the Attorney General of the State of New York may,
with the written  consent of the Bond Insurer,  and upon the written  request or
direction  of the Bond  Insurer or upon the written  request or direction of the
Holders of not less then  twenty-five  percent (25%) in principal  amount of the
Bonds then Outstanding  (determined in accordance with the provisions of Section
13.03) and the written consent of the Bond Insurer shall,  declare the principal
of and accrued  interest on all the Bonds then  Outstanding (if not then due and
payable) to be due and payable immediately, and upon

                                                       XII-2

such  declaration  the same shall become due and be immediately due and payable,
anything   contained  in  the  Bonds  or  in  this  Indenture  to  the  contrary
notwithstanding. If, however, at any time after the principal of the Bonds shall
have been so  declared  to be due and  payable,  and  before  the entry of final
judgment or decree in any suit,  action or  proceeding  instituted on account of
such Event of Default,  or before the completion of the enforcement of any other
remedy  under this  Indenture,  monies shall have  accumulated  in the Bond Fund
sufficient to pay the principal of and any premium (or redemption  price) on all
Bonds (or portions of the principal amount thereof) then or theretofore required
to be redeemed pursuant to any provisions of this Indenture (excluding principal
not then due except by reason of the aforesaid  declaration)  and all arrears of
interest and interest then due, if any, upon Bonds then  Outstanding  and if the
fees,  compensation,  expenses,  disbursements,  advances and liabilities of the
Trustee  and  all  other   amounts  then  payable  by  the  Company   under  the
Participation  Agreement,  the Note and the Insurance  Agreement shall have been
paid or a sum  sufficient  to pay the same  shall have been  deposited  with the
Trustee, and every other Event of Default known to the Trustee in the observance
or performance of any covenant, condition or agreement contained in the Bonds or
in this  Indenture  (other than default in the payment of the  principal of such
Bonds then due only because of a declaration under this Section) shall have been
remedied to the satisfaction of the Trustee and the Bond Insurer or, the Company
shall be taking,  or shall be causing  to be taken,  appropriate  action in good
faith to effect its cure,  then and in every such case the Trustee may, with the
written consent of the Bond Insurer and upon the written request or direction of
the Bond Insurer or upon the written  request or direction of the Holders of not
less than a majority in aggregate principal amount of the Bonds then Outstanding
(determined in accordance  with the provisions of Section 13.03) and the written
consent of the Bond Insurer shall,  by written notice to the Authority,  rescind
and  annul  such  declaration  and its  consequences;  provided,  however,  that
notwithstanding  any such rescission and annulment during an Auction Rate Period
the Bonds shall continue to bear interest at the Maximum Auction Rate and during
an Auction  Rate-Inverse Rate Period,  the Bonds shall continue to bear interest
at the Overdue Rate for the  applicable  period of time  determined  pursuant to
Article IIIA. No such  rescission  or annulment  pursuant to the next  preceding
sentence  shall extend to or affect any  subsequent  default or impair any right
consequent thereto.

                  SECTION 12.04.  Action by Trustee Upon  Occurrence of Event of
Default. Upon the occurrence and continuation of an Event of Default the Trustee
(i) for and on behalf of the  Holders of the Bonds and the Bond  Insurer,  shall
have the same rights  hereunder which are possessed by any Holders of the Bonds;
(ii)  shall be  authorized  to  proceed,  in its own name and as  trustee  of an
express trust; (iii) may pursue any available remedy by action at law or suit in
equity to enforce the payment of the  principal of and interest and premium,  if
any,  on the  Bonds;  (iv) may file such  proofs  of claim  and other  papers or
documents  as may be  necessary or advisable in order to have the claims of such
Trustee and of the  Bondholders  and of the Bond Insurer allowed in any judicial
proceedings relative to the Company,  its creditors,  its property or the Bonds;
and (v) may with the written  consent of the Bond Insurer,  and upon the written
request or direction of the Holders of not less than  twenty-five  percent (25%)
in principal amount of the Bonds then Outstanding (determined in accordance with
the  provisions  of  Section  13.03)  and with the  written  consent of the Bond
Insurer,  shall  proceed to protect and enforce all rights of the  Holders,  the
Bond Insurer and the Trustee under

and as permitted  by this  Indenture  and the laws of the State of New York,  by
such means or appropriate judicial proceedings as shall be suitable or deemed by
it most  effective  in the  premises,  including  the  appointment  of temporary
trustees and any actions, suits or special proceedings at law or in equity or in
bankruptcy  or by  proceedings  in the  office  of any board or  officer  having
jurisdiction, or otherwise, whether for the specific enforcement of any covenant
or agreement  contained in this  Indenture,  or in aid of execution of any power
granted in this  Indenture or to enforce any other legal or  equitable  right or
remedy vested in the Holders of the Bonds and the Bond Insurer or the Trustee by
this Indenture or by such laws, or for the appointment of a receiver. All rights
of action  (including the right to file proofs of claim) under this Indenture or
under any of the Bonds may be enforced by the Trustee  without the possession of
any of the Bonds or the of the Bond Insurer  production  thereof in any trial or
other proceedings  relating thereto.  Any such suit or proceeding  instituted by
the  Trustee  shall be brought  in its name and as  trustee of an express  trust
without the necessity of joining as plaintiffs or defendants  any Holders of the
Bonds or the Bond Insurer,  and any recovery or judgment  shall be for the equal
benefit of the Holders of the  Outstanding  Bonds and the Bond  Insurer as their
respective interests appear.

                  In the  enforcement  of any remedy  under this  Indenture  the
Trustee shall be entitled to sue for, enforce payment of and receive any and all
amounts,  then  or  during  any  Event  of  Default  becoming,  and at any  time
remaining, due from the Company and unpaid under the Participation Agreement and
the  Note  for  principal,  premium,  interest  or  otherwise  under  any of the
provisions of this Indenture or of the Bonds,  with interest on overdue payments
if such  interest  then is  permitted  by the  laws of the  State  of New  York,
together  with  any  and  all  costs  and  expenses  of  collection  and  of all
proceedings hereunder and under such Bonds, without prejudice to any other right
or remedy of the Trustee, of the Bond Insurer or of the Holders,  and to recover
and enforce  judgment or decree  against the Company  which is in default of its
respective  obligations  under the  Participation  Agreement  and the Note,  but
solely as  provided  herein and in such Bonds,  for any portion of such  amounts
remaining  unpaid,  with  interest,  costs and  expenses,  and to collect in any
manner provided by law, the monies  adjudged or decreed to be payable.  Any such
judgment shall be recovered by the Trustee, in its own name and as trustee of an
express trust.

                  SECTION 12.05. Powers of Trustee With Respect to Participation
Agreement  and Other  Agreements.  If the  payments  required  to be paid to the
Trustee  under  the  Participation  Agreement  and the Note or  other  agreement
pledged  and  assigned  hereunder,  as the case may be, are not paid when due or
upon the  happening and  continuance  of an Event of Default set forth in clause
(a) or (b) of Section 12.01,  the Trustee,  in its own name and as trustee of an
express  trust,  shall be entitled  and  empowered  to  institute  any action or
proceedings  at law or in equity  for the  collection  of all  payments  due and
unpaid under the Participation Agreement and the Note or other agreement, as the
case may be, and required to be paid to the Trustee and may  prosecute  any such
action or  proceedings  to  judgment or final  decree,  and may enforce any such
judgment or final  decree  against  the  Company or the obligor  under any other
agreement,  as the case may be, and collect in the manner provided by law out of
the  property  of the  Company or such  obligor  wherever  situated,  the monies
adjudged or decreed to be payable.

                                                       XII-4

                  In case there shall be pending  proceedings for the bankruptcy
or for the reorganization of the Company under the Participation Agreement or an
obligor under any other agreement  pledged and assigned  hereunder,  as the case
may be, under the Federal Bankruptcy Act or any other applicable law, or in case
a receiver or trustee shall have been  appointed for the property of the Company
under the  Participation  Agreement  and the Note or an obligor  under any other
agreement  pledged  and  assigned  hereunder,  as the case may be, the  Trustee,
regardless  of whether the  principal of the Bonds shall then be due and payable
as therein  expressed or by  declaration  or otherwise and regardless of whether
the Trustee  shall have made any demand  pursuant  to the power  vested in it by
this  Indenture,  shall be  entitled  and  empowered,  by  intervention  in such
proceedings  or  otherwise,  to file and prove a claim or  claims  for the whole
amount owing and unpaid under the  Participation  Agreement  and the Note by the
Company or under such other  agreement by such obligor,  as the case may be, and
to file such other papers or documents as may be necessary or advisable in order
to  have  the  claims  of  the  Trustee  (including  any  claim  for  reasonable
compensation  to the  Trustee,  its  agents,  attorneys  and  counsel,  and  for
reimbursement of all expenses and liabilities  incurred,  and all advances made,
by the Trustee except as a result of its  negligence,  wilful  misconduct or bad
faith) and of the Holders allowed in any such judicial  proceedings  relative to
the  Company  or  other  obligor,  as the case may be,  or to the  creditors  or
property of the Company or other obligor, as the case may be, and to collect and
receive any monies or other property payable or deliverable on such claims,  and
to distribute in accordance with the provisions hereof all amounts received with
respect to the claims of the Holders and of the Trustee on their behalf, and any
receiver,  assignee  or  trustee  in  bankruptcy  or  reorganization  is  hereby
authorized to make such payments to the Trustee.

                  Nothing  herein  contained  shall be deemed to  authorize  the
Trustee  to  authorize  or  consent  to or accept or adopt on behalf of the Bond
Insurer or any Holders any plan of  reorganization,  arrangement,  adjustment or
composition  affecting the Bonds or the rights of the Bond Insurer or any Holder
thereof, or to authorize the Trustee to vote in respect of the claim of the Bond
Insurer or any Holders in any such proceeding.

                  The  provisions  of this Section  shall not be construed as in
any way  limiting  the powers of the  Trustee,  with  respect to defaults by the
Authority or by the Company under the  Participation  Agreement and the Note, or
an obligor under any other agreement pledged and assigned hereunder, as the case
may be,  whether such powers be expressly or  implicitly  granted to the Trustee
elsewhere  in this  Indenture or in the  Participation  Agreement or the Note or
other  agreement,  as the case may be, or as a denial  that the  Trustee has any
such other powers,  but the powers  granted to the Trustee by this Section shall
be supplemental,  additional and cumulative to all other powers possessed by the
Trustee with respect to defaults under this Indenture or under the Participation
Agreement,  the Note or other agreement pledged and assigned  hereunder,  as the
case may be.

                  SECTION   12.06.   Disposition   of   Monies   in   Event   of
Insufficiencies  in Funds and  Accounts.  All monies (other than proceeds of any
Credit  Facility and amounts held in or payable to the Rebate Fund)  received by
the Trustee  pursuant to any right given or action taken under the provisions of
this  Article,  after  payment  of the costs  and  expenses  of the  proceedings
resulting  in the  collection  of such  monies  and of the  expenses,  fees  and
advances incurred or made by the Trustee

                                                       XII-5

hereunder, shall be deposited in the Bond Fund. If at any time the monies in the
Bond Fund shall not be  sufficient  to pay the interest or principal or premium,
if any (or the  redemption  price),  of the  Bonds  as the same  become  due and
payable (whether at maturity or upon  proceedings for the redemption  thereof or
by acceleration or otherwise),  the monies in such fund, together with any other
monies then available or thereafter becoming available for such purpose, whether
through  the  exercise  of the  remedies  provided  for in this  Article  XII or
otherwise, shall be applied as follows:

                  (a) Unless the  principal  of all the Bonds  shall have become
due and  payable or shall have been  declared  due and  payable  pursuant to the
provisions of Section 12.03, all such monies shall be applied:

                  First: to the payment to the persons  entitled  thereto of all
         installments  of interest then due, in the order of the maturity of the
         installments of such interest, and if the amount available shall not be
         sufficient  to pay in  full  any  particular  installment,  then to the
         payment ratably,  according to the amounts due on such installment,  to
         the persons entitled thereto, without any discrimination or preference;
         and

     Second:  to the payment of the  interest  and  premium,  if any, on and the
principal  of the Bonds,  to the  purchase  and  retirement  of Bonds and to the
redemption of Bonds, all in accordance with the provisions of this Indenture.

                  (b) If the  principal  of all the Bonds  shall have become due
and  payable  or shall  have  been  declared  due and  payable  pursuant  to the
provisions  of Section  12.03,  all such monies shall be applied  ratably to the
payment of the principal and interest then due and unpaid, with interest on such
principal  as  aforesaid,  without  preference  or  priority of  principal  over
interest or of interest over  principal,  or of any installment of interest over
any other installment of interest, or of any Bond over any other Bond, according
to the amounts due  respectively  for  principal  and  interest,  to the persons
entitled  thereto  without any  discrimination  or  preference  except as to any
difference in the respective rates of interest specified in the Bonds.

                  (c) If the principal of all the Bonds shall have been declared
due and  payable  pursuant  to the  provisions  of  Section  12.03,  and if such
declaration  shall  thereafter have been rescinded and annulled  pursuant to the
provisions  of  such  Section  12.03,   then,   subject  to  the  provisions  of
subparagraph  (b) above of this paragraph in the event that the principal of all
the Bonds  shall later  become due and  payable or be  declared  due and payable
pursuant to the  provisions of Section  12.03,  the monies then held in the Bond
Fund  shall be  applied  to the  payment of the  principal  of and  premium  (or
redemption  price)  on all  matured  Bonds and all  Bonds  (or  portions  of the
principal amount thereof) then or theretofore  required to be redeemed  pursuant
to any provisions of this Indenture  (excluding principal not then due except by
reason of such  declaration)  and all arrears of interest and interest then due,
if any, upon all Bonds then Outstanding,  and any monies thereafter deposited in
the Bond Fund shall be applied in accordance with the provisions of Article IX.

                                                       XII-6

<PAGE>



                  Whenever  monies are to be applied by the Trustee  pursuant to
the  provisions of  subparagraphs  (a) and (b) of this Section,  (i) such monies
shall be applied by the  Trustee at such  times,  and from time to time,  as the
Trustee in its sole discretion shall determine,  having due regard to the amount
of such monies available for application and the likelihood of additional monies
becoming available for such application in the future;  (ii) the deposit of such
monies, in trust for the proper purpose,  shall constitute proper application by
the Trustee;  and (iii) the Trustee  shall incur no liability  whatsoever to the
Authority,  to any Holder or to any other  person for any delay in applying  any
such monies, so long as the Trustee acts with reasonable  diligence,  having due
regard to the circumstances,  and ultimately applies the same in accordance with
such  provisions  of  this  Indenture  as  may be  applicable  at  the  time  of
application by the Trustee.  Whenever the Trustee shall exercise such discretion
in  applying  such  monies,  it shall fix the date  (which  shall be an Interest
Payment  Date unless the Trustee  shall deem another  date more  suitable)  upon
which such  application is to be made and upon such date interest on the amounts
of  principal to be paid on such date shall cease to accrue.  The Trustee  shall
give such notice as it may deem  appropriate of the fixing of any such date, and
shall not be  required  to make  payment to the Holder of any unpaid  Bond until
such Bond shall be surrendered to the Trustee for  appropriate  endorsement,  or
for cancellation if fully paid.

                  SECTION 12.07. Effect of Delay or Omission; Waiver of Default;
Direction of Remedial  Proceedings  by the Holders.  No delay or omission of the
Trustee, the Bond Insurer or of any Holder of the Bonds to exercise any right or
power  accruing upon any default or Event of Default shall impair any such right
or  power  or  shall  be  construed  to be a  waiver  of  any  such  default  or
acquiescence therein.

                  Anything in this  Indenture to the  contrary  notwithstanding,
the Bond Insurer or the Holders of not less than a majority in principal  amount
of the  Bonds  at the  time  Outstanding  (determined  in  accordance  with  the
provisions of Section  13.03),  with the prior consent of the Bond Insurer shall
be authorized  and empowered and have the right,  by an instrument or concurrent
instruments in writing delivered to the Trustee on behalf of the Bond Insurer or
the Holders of the Bonds then Outstanding and the Bond Insurer to consent to the
waiver of any Event of Default or its consequences,  and the Trustee shall waive
any Event of Default and its  consequences  upon the written request of the Bond
Insurer  or the  Holders  of such  majority  with the prior  consent of the Bond
Insurer;  provided,  however,  that there shall not be waived (i) any default in
payment of principal or premium when due or (ii) any default in payment when due
of  interest  unless,  in either  case,  prior to such  waiver  all  arrears  in
principal,  premium,  if any, and interest,  with  additional  interest,  to the
extent permitted by law, at the rate then borne by the Bonds (which, in the case
of Auction Rate Bonds during an Auction Rate Period shall be the Maximum Auction
Rate and in the case of  Auction  Rate-Inverse  Rate  Bonds  during  an  Auction
Rate-Inverse  Rate Period shall be the Overdue Rate),  and all fees and expenses
of the Trustee shall have been paid or provided  for;  provided,  however,  that
notwithstanding  any such waiver,  any Auction Rate Bonds during an Auction Rate
Period  shall  continue to bear  interest at the  Maximum  Auction  Rate and any
Auction Rate-Inverse Rate Bonds during an Auction Rate-Inverse Rate Period shall
continue to bear  interest at the  Overdue  Rate until cured or waived.  No such
waiver shall extend to or affect any other

                                                       XII-7

existing  or  subsequent  default  or Event of  Default  or impair any rights or
remedies consequent thereon.

                  Anything in this  Indenture to the  contrary  notwithstanding,
the Bond Insurer or the Holders of not less than  twenty-five  percent  (25%) in
aggregate  principal amount of the Bonds at the time Outstanding  (determined in
accordance  with the  provisions of Section 13.03) with the prior consent of the
Bond  Insurer,  shall be  authorized  and  empowered  and have the right,  by an
instrument  or  concurrent  instruments  in writing  delivered to the Trustee to
direct the time and method of  conducting  any  proceeding  for any remedy to be
taken by the  Trustee  or  available  to the  Trustee or  available  to the Bond
Insurer or the Holders of the Bonds,  or exercising any trust or power conferred
upon the Trustee hereunder provided: (1) such direction shall not be in conflict
with any rule of law or with this  Indenture  or expose the  Trustee to personal
liability,  or be unduly prejudicial to Holders not joining therein, and (2) the
Trustee may take any other  action  deemed  proper by the  Trustee  which is not
inconsistent with such direction.

                  SECTION  12.08.  Suits or Actions by  Holders;  Any Holder May
Enforce  Overdue  Payment  of His Bond or  Interest  Thereon.  Neither  the Bond
Insurer nor the Holder of any of the Bonds shall have any right to institute any
suit,  action or  proceeding  in equity or at law for the execution of any trust
hereunder or for any other remedy  hereunder unless there shall have occurred an
Event of Default of which the  Trustee  has been  notified  or is deemed to have
notice as  provided  in  Section  11.08,  and the Bond  Insurer  or such  Holder
previously  shall  have  given to the  Trustee  written  notice  of the Event of
Default on account of which such suit, action or proceeding is to be instituted,
and  unless  also the  Holders  of not less than  twenty-five  percent  (25%) in
principal amount of the Bonds then  Outstanding  shall have made written request
of the Trustee  after the right to exercise  such powers or right of action,  as
the case may be,  shall have  accrued,  shall have  obtained  the prior  written
consent of the Bond  Insurer  to the  institution  of any such  suit,  action or
proceeding  in equity or at law, and shall have afforded the Trustee a period of
60 days  either to proceed to  exercise  the  powers  hereinabove  granted or to
institute  such action,  suit or  proceeding  in its or their name,  the Trustee
shall  have  been  indemnified  by  Holders  against  the  costs,  expenses  and
liabilities to be incurred in compliance  with such request,  and shall not have
received an inconsistent direction from the Holders of not less than twenty-five
percent  (25%) in  principal  amount  of the Bonds and the  Trustee  shall  have
refused or neglected to comply with such request within a reasonable time. It is
understood  and intended that no one or more Holders of the Bonds hereby secured
shall have any right in any  manner  whatever  by the  action of such  Holder or
Holders to affect,  disturb or prejudice the security of this  Indenture,  or to
enforce  any right  hereunder  except in the manner  herein  provided;  that all
proceedings at law or in equity shall be  instituted,  had and maintained in the
manner  herein  provided and for the benefit of all Holders of such  Outstanding
Bonds;  and that any individual  rights of action or other right given to one or
more of such Holders by law are  restricted by this  Indenture to the rights and
remedies herein provided.  Notwithstanding  the foregoing,  the Trustee shall be
under no obligation to exercise any of the rights or powers vested in it by this
Indenture at the request or direction of the Bond Insurer or any of the Holders,
unless  the Bond  Insurer or such  Holders  shall  have  offered to the  Trustee
reasonable security or indemnity against

                                                       XII-8

<PAGE>



the costs,  expenses and liabilities which might be incurred by it in compliance
with such request or direction.

                  Notwithstanding  any other  provision of this  Indenture,  the
right of any Holder of a Bond to receive  payment of the principal of,  premium,
if any,  and  interest  on such  Bond,  on or after  the  respective  due  dates
expressed in such Bond,  or to institute  suit for the  enforcement  of any such
payment on or after such  respective  dates,  shall not be  impaired or affected
without the consent of such Holder, except that no Holder of any such Bond shall
have the  right  to  institute  any such  suit,  if and to the  extent  that the
institution or prosecution thereof or the entry of judgment therein would, under
applicable law, result in the surrender, impairment, waiver, or loss of the lien
of this Indenture.

                  SECTION 12.09. Remedies Not Exclusive.  No remedy by the terms
of this Indenture conferred upon or reserved to the Trustee, the Bond Insurer or
the  Holders of the Bonds is  intended to be  exclusive  of any other  remedy so
conferred  or reserved or to be  exclusive  of other  remedies  now or hereafter
existing at law or in equity or by statute, and each and every such remedy shall
be  cumulative  and shall be in addition to any other remedy given  hereunder to
the Trustee or to the Holders of the Bonds or now or  hereafter  existing at law
or in equity or by statute.  Every such right,  power and remedy given hereunder
or by law or in equity or by statute may be  exercised  from time to time and as
often as may be deemed expedient.

                  SECTION  12.10.   Effect  of  Abandonment  of  Proceedings  on
Default.  In case any proceeding  taken by the Trustee,  the Bond Insurer or the
Holders  of the  Bonds on  account  of any  Event of  Default  shall  have  been
discontinued  or  abandoned  for any  reason,  then and in every  such  case the
Authority,  the Trustee,  the Bond Insurer and the Holders  shall be restored to
their  former  positions  and rights  hereunder,  respectively,  and all rights,
remedies,  powers and duties of the  Trustee  shall  continue  as though no such
proceeding had been taken.

                  SECTION  12.11.  Interest  on Overdue  Amounts.  To the extent
permitted  by law all amounts  which are due and payable but which have not been
so paid under this  Indenture  shall bear  interest at the then  current rate of
interest  on the Bonds until paid;  provided,  however,  that during any Auction
Rate Period all amounts which are due and owing but unpaid  hereunder shall bear
interest at the Maximum  Auction Rate and during any Auction  Rate-Inverse  Rate
Period  all  amounts  which are due and owing but  unpaid  hereunder  shall bear
interest at the Overdue Rate until paid.

                  SECTION 13.01. Execution of Requests,  Directions and Consents
and Other  Instruments and Proof of Same;  Ownership of Bonds and Proof of Same.
Any request,  direction,  consent or other instrument required by this Indenture
to be signed or  executed  by Holders of Bonds may be signed or executed by such
Holders in person or by agent or agents duly appointed in writing, and may be in
any number of concurrent  writings of substantially  similar tenor. Proof of the
execution of any such request,  direction,  consent or other  instrument or of a
writing  appointing  any such agent,  and of the holding or  ownership of Bonds,
shall be sufficient for any purpose of this Indenture and shall be conclusive in
favor of the Trustee  hereunder with regard to any action taken by it under such
request,  direction,  consent or other  instrument or of writing  appointing any
such agent, if made in the following manner:

                  (a) the fact and date of the  execution  by any  person of any
         such request, direction,  consent or other instrument in writing may be
         proved in any reasonable manner which the Trustee deems sufficient;

     (b) the  ownership  of Bonds shall be proved by the books of registry  kept
under the provisions of this Indenture.

                  Any request,  direction,  consent or vote of the Holder of any
Bond  shall bind and be  conclusive  upon the  Holder of such Bond  giving  such
request,  direction or consent or casting such vote and upon every future Holder
of the same Bond in  respect  of  anything  done or  suffered  to be done by the
Trustee or  otherwise,  or by the Holders of other  Bonds,  in pursuance of such
request,  direction,  consent or vote, and whether or not such future Holder has
knowledge of or  information  as to such  request,  direction,  consent or vote;
provided  that any request,  direction,  consent or vote of the Holder of a Bond
required  by any of the  provisions  hereof may be revoked by the Holder  giving
such  request,  direction,  consent  or vote or by a  subsequent  Holder if such
revocation  in  writing is filed  with the  Trustee,  prior to the time when the
request,  direction,  consent or vote of the  percentage  of the  Holders of the
Bonds required by such  provision  shall have been given and action taken by the
Trustee or otherwise,  or by the Holders of other Bonds, under authority of such
request, direction, consent or vote.

                  The payment of or on account of principal to or upon the order
of the person in whose name the Bonds  shall at the time be  registered  on said
books of registry and the payment of interest to or upon the order of any person
in  whose  name the  Bonds  shall at the  time be  registered  on said  books of
registry,  shall be valid and  effectual  fully to  satisfy  and  discharge  all
liability hereunder or upon the Bonds to the extent of the sum or sums so paid.

                                                      XIII-1

                  The  Authority  at the request of the Company may  establish a
record date for the taking of any action by the Holders.

                  SECTION 13.02. Meetings of Holders. The Trustee or the Holders
of not less than twenty percent (20%) in aggregate principal amount of the Bonds
then  Outstanding may at any time call a meeting of the Holders of the Bonds for
the  purpose  of the  consenting  to,  the  approving,  the  requesting,  or the
directing by the Holders of the Bonds of any action  required to be consented to
or approved by them  hereunder or which they may request or direct  hereunder to
be taken,  or for the making by the  Holders of any  appointments  they may make
hereunder,  or for the purpose of taking any other  action which the Holders may
take hereunder,  or for any other purpose concerning the payment and security of
the Bonds hereunder.  Every such meeting shall be held at such place in The City
of New York,  State of New York, as may be specified in the notice  calling such
meeting.  Written  notice  of such  meeting,  stating  the place and time of the
meeting and in general  terms the business to be  submitted,  shall be mailed to
the Holders whose names and addresses  then appear upon the books of registry by
the  Registrar and Paying Agent or the Holders  calling such  meeting,  not less
than 20 days nor more than 60 days before such  meeting.  Any meeting of Holders
shall,  however,  be valid  without  notice if the  Holders  of all  Bonds  then
Outstanding  are present in person or by proxy or if notice is waived  before or
within 30 days after the meeting by those not so present.

                  Attendance and voting by Holders at meetings thereof may be in
person or by proxy.  Holders of Bonds may,  by an  instrument  in writing  under
their hands, appoint any person or persons, with full power of substitution,  as
their proxy to attend and vote at any meeting for them.

                  Persons  named by the Trustee,  or elected by the Holders of a
majority in principal  amount of the Bonds  represented at the meeting in person
or by proxy in the event the Trustee is not  represented at such meeting,  shall
act as temporary  Chairman and temporary  Secretary of any meeting of Holders. A
permanent Chairman and a permanent Secretary of such meeting shall be elected by
the Holders of a majority in aggregate principal amount of the Bonds represented
at such  meeting in person or by proxy.  The  permanent  Chairman of the meeting
shall appoint two (2) Inspectors of Votes who shall count all votes cast at such
meeting,  except votes on the election of Chairman and  Secretary as  aforesaid,
and who shall make and file with the  Secretary  of the  meeting and the Trustee
their verified report of all such votes cast at the meeting.

                  The Holders of not less than the aggregate principal amount of
the Bonds required by the provisions  hereof to consent to, approve,  request or
direct  any  action to be taken at a meeting  of  Holders,  or  required  by the
provisions  hereof  to make  any  appointments  to be made at such  meeting,  or
required by the  provisions  hereof to take any other action to be taken at such
meeting,  must be  present  at such  meeting  in  person or by proxy in order to
constitute a quorum for the  transaction of such  business.  Less than a quorum,
however,  shall have  power to adjourn  the  meeting  from time to time  without
notice of such adjournment  other than the announcement  thereof at the meeting;
provided,  however,  that if such meeting is adjourned by less than a quorum for
more  than ten  (10)  days,  notice  of such  adjournment  shall be given by the
Trustee at least five (5) days prior to the adjourned date of the meeting.

                                                      XIII-2

                  Any Holder of a Bond shall be  entitled  in person or by proxy
to attend and vote at such meeting as Holder of the Bond or Bonds  registered in
his or her name  without  producing  such Bond or Bonds.  Such persons and their
proxies shall, if required,  produce such proof of personal identity as shall be
satisfactory to the Secretary of the meeting.

                  All proxies  presented at such  meeting  shall be delivered to
the Inspector of Votes and filed with the Secretary of the meeting. The right of
a proxy for a Holder to  attend  the  meeting  and act and vote  thereat  may be
proved (subject to the Trustee's right to require additional proof) by a written
proxy executed by such Holder as aforesaid.

                  The  officers  or  nominees  of the  Trustee may be present or
represented at such meeting and take part therein,  but shall not be entitled to
vote  thereat,  except for such  officers or nominees who are Holders or proxies
for Holders (including the Trustee).

                  The vote at any such meeting of the Holder of any Bond, or his
or her proxy,  entitled to vote  thereat  shall be binding  upon such Holder and
upon every subsequent Holder of such Bond (whether or not such subsequent Holder
has notice thereof).

                  SECTION  13.03.   Exclusion  of  Bonds  Held  by  or  for  the
Authority,  the Company and of Bonds No Longer Deemed Outstanding Hereunder.  In
determining  whether the Holders of the requisite  aggregate principal amount of
Bonds have concurred in any demand, request, direction,  consent, vote or waiver
under this  Indenture,  any Bonds  which are owned by or on behalf of or for the
account of the  Authority,  the Company and,  except for the purposes of Section
15.01,  any Bonds  which are  deemed no longer  Outstanding  hereunder  shall be
disregarded and not included for the purpose of any such determination, and such
Bonds  shall not be  entitled  to vote upon,  consent to or concur in any action
provided in this Indenture,  except that for the purposes of determining whether
the  Trustee  shall  be  protected  in  relying  on any  such  demand,  request,
direction,  consent, vote or waiver only Bonds which the Trustee knows are owned
as aforesaid shall be disregarded. The Trustee may require each Holder of a Bond
or Bonds,  before such Holder's demand,  request,  direction,  consent,  vote or
waiver  shall be deemed  effective,  to  reveal  if the  Bonds as to which  such
demand,  request,  direction,  consent, vote or waiver is made, granted, cast or
given are disqualified as provided in this Section.

                  (g) to provide for the substitution of rating agencies;

                  (h) to  provide  for  any  new  administrative  or  procedural
         provisions  made  necessary  or  desirable by the issuance of a Support
         Facility or an Alternate Support Facility,  other credit,  liquidity or
         support  facility,   including,  but  not  limited  to,  any  amendment

                  (j) to  modify,  amend or  supplement  the  Indenture  in such

         determine,  to add to the Indenture,  such other terms,  conditions and
         provisions as may be required to permit such qualification.

                  No Supplemental  Indenture shall be entered into unless in the
opinion of Bond  Counsel  which shall be  delivered  to the Trustee and the Bond
Insurer  (which  opinion  may be combined  with the opinion  required by Section
14.04)  the  execution  of  such  Supplemental  Indenture  is  permitted  by the
foregoing  provisions of this Section and the  provisions  of such  Supplemental
Indenture do not  materially  and adversely  affect the rights of the Holders of
the Bonds and the Trustee may rely on any such opinion.

                  SECTION  14.02.  Amending  and  Supplementing  Indenture  with
Consent of Holders.  With the consent of the Holders of not less than  fifty-one
percent (51%) in aggregate  principal amount of the Bonds then Outstanding,  the
Authority and the Trustee,  with the prior  written  consent of the Bond Insurer
and prior  written  notice to each  Rating  Agency  then rating the Bonds at the
request  of the  Company,  from  time to time and at any time may  enter  into a
Supplemental Indenture for the purpose of adding any provisions, to, or changing
in any manner or  eliminating  any of the  provisions,  of, this  Indenture,  or
modifying or amending the rights and obligations of the Authority hereunder,  or
modifying  or amending in any manner the rights of the Holders;  provided  that,
without the  specific  consent of the Bond  Insurer and the Holders of all Bonds
Outstanding which would be affected thereby no Supplemental  Indenture  amending
or supplementing the provisions hereof shall: (a) change the fixed maturity date
for the payment of the  principal  of any Bond,  or the dates for the payment of
interest thereon or the terms of the purchase or redemption  thereof,  or reduce

consent to any Supplemental  Indenture  amending or supplementing the provisions
of this  Indenture;  or (c) give to any Bond any preference  over any other Bond
secured  hereby;  or (d)  authorize  the creation of any pledge of Note Payments
prior or superior to the pledge of a lien and charge thereon assigned herein for

                                                       XIV-2

any other Funds or Accounts  established thereby shall not be deemed a change in
the terms of payment;  provided that no such  modification  or amendment  shall,
except  upon the  consent  of the Bond  Insurer  and the  Holders  of all  Bonds
Outstanding  affected  thereby,  reduce  the amount or  amounts  required  to be
deposited in the Bond Fund. Nothing in this paragraph contained,  however, shall
be construed as making necessary the approval of the Holders of the execution of
any Supplemental Indenture authorized by the provisions of Section 14.01.

                  The proof of the giving of any consent by any Holder  required
by this  Section  and of the  holding  of the  Bonds for the  purpose  of giving
consents  shall be made in  accordance  with the  provisions of Article XIII. It
shall not be necessary  that the consent of the Holders  approve the  particular
form of wording of the proposed Supplemental  Indenture effecting such amendment
or supplement, but it shall be sufficient if such consent approves the substance
of the  proposed  amendment  or  supplement.  After the Holders of the  required
percentage  of  Bonds  shall  have  filed  their  consents  to the  amending  or
supplementing  hereof pursuant to this Section,  the Authority shall mail a copy
of notice of such consent, postage prepaid, to each Holder at his or her address
as it appears  upon the books of registry  and to the  Trustee.  Nothing in this
paragraph  contained,  however,  shall be construed  as requiring  the giving of
notice of any amending or  supplementing  of this  Indenture  authorized by this
Section. A record of the consents shall be filed with the Trustee,  and shall be
proof of the matters  therein stated until the contrary is proved.  No action or
proceeding to set aside or invalidate such Supplemental  Indenture or any of the
proceedings  for its adoption  shall be  instituted  or  maintained  unless such
action or  proceeding  is commenced  within sixty (60) days after the mailing of
the notice required by this paragraph.

                  Copies  of  any  Supplemental   Indenture  authorized  by  the
provisions of Section 14.02 shall be given to the Rating Agency or Agencies then
rating the Bonds.

                  SECTION  14.03.  Notation  upon Bonds;  New Bonds  Issued upon
Amendments.  The Bonds delivered after the effective date of any action taken as
provided in this Article,  if any, may and shall if required by the Trustee bear
a notation as to such action,  by  endorsement or otherwise and in form approved
by the Authority. In that case, upon demand of any Holder at such effective date
and upon  presentation of Bonds at the principal  office of the Trustee or other
transfer  agent or registrar  hereunder for such Bonds,  and at such  additional
offices,  if any, as the Authority may select and designate for that purpose,  a
suitable notation shall be made on the Bonds.

                  SECTION 14.04. Effectiveness of Supplemental Indentures.  Upon
the  execution  pursuant to this Article by the Authority and the Trustee of any
Supplemental   Indenture  amending  or  supplementing  the  provisions  of  this
Indenture  and the delivery to the Trustee and the Bond Insurer of an opinion of
Bond Counsel  that such  Supplemental  Indenture  is in due form,  has been duly
executed in accordance  with the  provisions  hereof and applicable law and that
the provisions thereof are valid (upon which opinion the Trustee, subject to the
provisions of Section 11.04, shall be fully protected in relying),  or upon such
later  date  as may be  specified  in  such  Supplemental  Indenture,  (i)  this
Indenture  and the Bonds shall be modified and amended in  accordance  with such
Supplemental  Indenture;  (ii) the  respective  rights,  limitations  of rights,
obligations, duties and

                                                       XIV-3

immunities under this Indenture of the Authority,  the Trustee,  and the Holders
shall  thereafter be  determined,  exercised and enforced  under this  Indenture
subject in all respects to such  modifications and amendments;  and (iii) all of
the terms and conditions of any such  Supplemental  Indenture shall be a part of
the terms and  conditions  of the  Bonds and of this  Indenture  for any and all
purposes.

                  SECTION  14.05.   Supplemental   Indenture  Affecting  Support
Facility Provider. No Supplemental Indenture in any way materially and adversely
affecting any Support  Facility  Issuer (so long as such Support  Facility is in
effect) may be entered into by the  Authority and the Trustee or be consented to
by the Holders without written consent of such Support Facility Issuer.

                  SECTION  14.06.  Supplemental   Participation  Agreements  Not
Requiring  the Consent of the Holders.  The  Authority and the Company may, with
the  written  consent of the  Trustee  but  without  notice to or consent of any
Holder, from time to time and at any time, agree to such supplemental agreements
supplementing  the  Participation  Agreement or amendments to the  Participation
Agreement  as shall not be  inconsistent  with the terms and  provisions  of the
Participation  Agreement or this Indenture and, in the opinion of the Authority,
shall not be  detrimental  to the interests of the Holders  (which  Supplemental
Participation  Agreements  shall  thereafter  form a part  of the  Participation
Agreement):

     (a) to cure any ambiguity or formal defect or omission in the Participation
Agreement or in any supplemental agreement;

                  (b) to grant to or confer  upon the Trustee for the benefit of
         the Holders any  additional  rights,  remedies,  powers,  authority  or
         security that may lawfully be granted to or conferred  upon the Holders
         or the Trustee;

     (c)  to  provide  for  any  new  administrative,   security  or  procedural
provisions necessitated by the issuance of an Alternate Support Facility; or

          (d) to provide for or add any further changes or corrections  that are
     necessary or desirable to comply with any  Supplemental  Indenture  entered
     into pursuant to Section 14.01;

provided that no such Supplemental  Participation  Agreement or the amendment to
the Note which materially and adversely  affects any Support Facility Issuer (so
long as such  Support  Facility is in effect)  shall be  effective  prior to the
receipt by such  parties of the  written  consent of the issuer of such  Support
Facility.

                  SECTION   14.07.   Notice   and   Consent   for   Supplemental
Participation  Agreements  Requiring  the  Consent  of the  Holders.  Except for
Supplemental  Participation  Agreements  or  amendments  provided for in Section
14.06, neither the Authority nor the Trustee shall agree or consent, as the case
may  be,  to  any  Supplemental  Participation  Agreement  or  amendment  to the
Participation  Agreement  unless  notice  of  the  proposed  execution  of  such
Supplemental  Participation Agreement or amendment shall have been given and the
Bond Insurer and the Holders shall have

                                                       XIV-4

<PAGE>



consented to and approved the  execution  thereof in the same manner and form as
provided for in Section 14.02 in the case of Supplemental  Indentures;  provided
that no such Supplemental Participation Agreement which materially and adversely
affects  any  Support  Facility  Issuer (so long as the  issuer of such  Support
Facility is in effect)  shall be effective  prior to the receipt by such parties
of the written consent of such Support Facility Issuer.

                  SECTION 14.08.  Effectiveness  of  Supplemental  Participation
Agreement.  Upon the execution pursuant to this Article and of applicable law by
the  Authority  and the  Company  of any  Supplemental  Participation  Agreement
amending or supplementing the provisions of the Participation  Agreement and the
delivery to the Trustee and the Bond  Insurer of an Opinion of Bond Counsel that
such Supplemental Participation Agreement is in due form, has been duly executed
in  accordance  with  the  provisions  hereof  and  applicable  law and that the
provisions  thereof are valid (upon which  opinion the  Trustee,  subject to the
provisions of Section 11.04, shall be fully protected in relying),  or upon such
later date as may be specified in such Supplemental Participation Agreement, (i)
the  Participation  Agreement  shall be modified and amended in accordance  with
such  Supplemental   Participation   Agreement;   (ii)  the  respective  rights,
limitations  of rights,  obligations,  duties and  immunities  thereunder of the
Authority and the Company shall thereafter be determined, exercised and enforced
thereunder  subject in all respects to such  modifications  and amendments;  and
(iii) all of the terms and  conditions  of any such  Supplemental  Participation
Agreement  shall be a part of the terms and  conditions  thereof for any and all

Rating Agency then rating the Bonds.

                                                  DEFEASED BONDS

                  SECTION 15.01. Discharge of Liens and Pledges; Bonds No Longer
Deemed to be Outstanding Hereunder.  Bonds purchased on or before the Fixed Rate
Conversion  Date  pursuant to Section  5.02,  5.03 or 5.08 shall  continue to be
Outstanding  hereunder  until such Bonds shall be cancelled in  accordance  with
Section 5.14 or paid at maturity or redeemed  pursuant to Article V or otherwise
defeased.  The  obligations of the Authority under this Indenture and the liens,
pledges, charges, trusts, covenants and agreements of the Authority, herein made
or  provided  for,  shall be,  subject  to the  terms of  Section  15.02,  fully
discharged and satisfied as to the Bonds or portion  thereof and the Bonds shall
no longer be deemed to be Outstanding hereunder:

                  (a) when the Bonds  shall have been  cancelled,  or shall have
been surrendered for cancellation and are subject to cancellation, or shall have
been redeemed by the Trustee from monies held by it under this Indenture; or

                  (b) if the Bonds have not been cancelled or so surrendered for
cancellation  or subject to  cancellation,  or so redeemed,  when payment of the
principal of and premium,  if any, on the Bonds, plus interest on such principal
to the due date thereof  (whether such due date be by reason of maturity or upon
redemption  or  prepayment,  or  otherwise)  either  (i) shall have been made or
caused to be made in accordance with the terms thereof,  or (ii) shall have been
provided  for  by  irrevocably   depositing  with  the  Trustee  in  trust,  and
irrevocably  appropriating  and setting aside  exclusively for such payments (1)
monies  sufficient to make such payment without  investment or reinvestment,  or
(2)  Governmental  Obligations  maturing as to  principal  and  interest in such
amounts  and at such times as will insure the  availability  of  sufficient  and
timely monies to make such payments when due, or (3) a combination  of both such
monies and Governmental Obligations,  whichever the Authority deems to be in its
best interest,  and all necessary and proper fees,  compensation and expenses of
the Trustee  pertaining  to the Bonds or portion  thereof  with respect to which
such deposit is made,  shall have been paid or the payment  thereof  provided to
the satisfaction of the Trustee.  Notwithstanding the foregoing, Bonds shall not
be deemed defeased  hereunder unless the Trustee and the Bond Insurer shall have
received a verification  report of an independent  certified  public  accountant
relating to the  sufficiency  of the escrowed funds to be used for defeasance in
form and substance  reasonably  satisfactory to them, written evidence from each
Rating  Agency then  rating the Bonds that the current  rating on the Bonds will
not be lowered or withdrawn,  and an opinion of Bond Counsel,  which may rely on
such  verification  report  substantially  to the  effect  that the Bonds are no
longer outstanding under the Indenture.  Any escrow agreement entered into under
this  Section  15.01  shall not permit the use of any  forward  supply  contract
providing for the delivery and purchase of Government  Obligations  in an escrow
fund without the approval of the Authority and the Bond Insurer.

                  At such  time as the  Bonds  shall be  deemed  to be no longer
Outstanding hereunder,  as aforesaid,  such Bonds shall cease to accrue interest
from the due date thereof  (whether  such due date occurs by reason of maturity,
or upon  redemption or prepayment or otherwise)  and, except for the purposes of
any such payment from such monies or Governmental Obligations and except, in the
case of Auction Rate Bonds and Inverse Rate Bonds, to the extent provided in the
definition of Outstanding in Article I shall no longer be secured by or entitled
to the benefits of this Indenture.

                  Any such monies so  deposited  with the Trustee as provided in
this  Section  may  at  the  direction  of  the  Company  also  be  invested  in
Governmental Obligations,  maturing in the amounts and times as hereinbefore set
forth,  and all income  from all  Governmental  Obligations  in the hands of the
Trustee  pursuant to this  Section  which is not required for the payment of the
Bonds and interest  thereon with respect to which such monies shall have been so
deposited shall be paid to the Company or if any Bonds are then Outstanding,  be
deposited  in the Bond Fund and  credited to the  Principal  Account as and when
realized and collected,  for use and application as are other monies credited to
such Account.

                  Anything in Article XIV to the contrary  not-withstanding,  if
monies or  Governmental  Obligations  have been  deposited or set aside with the
Trustee  pursuant to this Section for the payment of the Bonds,  the Bonds shall
be deemed to have been paid in full.  No  amendment  to the  provisions  of this
Article  shall be made without the consent of the Holders of the Bonds  affected
thereby.

                  Notwithstanding  anything in this  Indenture to the  contrary,
unless  payment of such Bonds (or provision  for such  payment)  shall have been
made with Available  Moneys, no Bonds bearing interest at a Daily Rate, a Weekly
Rate, a Monthly  Rate, a  Semi-annual  Rate or a Commercial  Paper Rate shall be
deemed to be paid within the meaning of this  Section  unless and until at least
123 days shall have elapsed  subsequent  to payment or provision  for payment of
such Bonds shall have been made in  accordance  with this  Section  15.01 during
which no Act of Bankruptcy shall have occurred or be continuing.  The occurrence
or  continuance  of an Act of  Bankruptcy  shall be  evidenced  by delivery of a
certificate of the Company.

                  Notwithstanding  anything to the  contrary,  in the event that
the principal and/or interest due on the Bonds shall be paid by the Bond Insurer
pursuant  to the  Municipal  Bond  Insurance  Policy,  the  Bonds  shall  remain
Outstanding for all purposes,  not be defeased or otherwise satisfied and not be
considered  paid by the Company,  and  obligations  of the Authority  under this
Indenture and the liens, pledges,  charges,  trusts, covenants and agreements of
the Authority, herein made or provided for shall continue to exist and shall run
to the benefit of the Bond Insurer,  and the Bond Insurer shall be subrogated to
the rights of the Holders of the Bonds.

                  The Trustee shall promptly  surrender any Support Facility (if
appropriate  for the type of instrument or  instruments  then serving as Support
Facility)  to the issuer of such  Support  Facility  for  cancellation  or shall
otherwise take appropriate  action to terminate the Support  Facility  following
any such defeasance.

                  SECTION  15.02.  Release of Indenture,  Termination  of Right,
Title and  Interest  of  Trustee.  When all Bonds  shall be deemed to be paid in
accordance with the provisions of Section 15.01, then and in the case all right,
title and interest of the Trustee under this Indenture  shall  thereupon  cease,
terminate  and become  void,  and the  Trustee in such case shall  release  this
Indenture,  shall  execute  such  documents  to evidence  such release as may be
reasonably  required by the Authority  and furnish the Authority  with the same,
and shall turn over to the Company any surplus monies and balances  remaining in
any of the Funds and  Accounts  created in or held under this  Indenture,  other
than monies and Governmental Obligations held by it pursuant to Section 15.01 or
the provisions of Section 15.03 for the redemption, payment or prepayment of the
Bonds and, except to the extent provided in the Tax Regulatory Agreement, monies
held in the Investment Proceeds Account and in the Rebate Fund; otherwise,  this
Indenture shall be, continue and remain in full force and effect.

                  Notwithstanding   the   satisfaction  and  discharge  of  this
Indenture,  the rights of the Trustee and the  Registrar  and Paying Agent under
Sections 11.02, 11.06 and 11.17 shall survive defeasance of the Bonds hereunder.

                  SECTION  15.03.  Bonds Not  Presented  for  Payment  When Due;
Monies Held for the Bonds after Due Date of Bonds.  Subject to the provisions of
the next  sentence of this  paragraph,  if the Bonds shall not be presented  for
payment when the principal  thereof shall become due,  whether at maturity or at
the date  fixed  for the  redemption  thereof,  or  otherwise,  and if monies or
Governmental  Obligations shall at such due date be held by the Trustee in trust
for that purpose  sufficient  and available to pay the principal of and premium,
if any, on the Bonds,  together  with all interest due on such  principal to the
due date thereof or to the date fixed for redemption  thereof,  all liability of
the Authority and the Company for such payment shall forthwith cease,  determine
and be completely discharged,  and thereupon it shall be the duty of the Trustee
to hold said monies or Governmental Obligations without liability to the Holders
for interest thereon, in trust for the benefit of the Holders,  which thereafter
shall be restricted  exclusively to said monies or Governmental  Obligations for
any  claim of  whatever  nature  on its part on or with  respect  to the  Bonds,
including for any claim for the payment thereof. Any such monies or Governmental
Obligations held by the Trustee for the Holders after the principal of the Bonds
or any  portion  thereof  with  respect  to which  such  monies or  Governmental
Obligations  have been so set aside  has  become  due and  payable  (whether  at
maturity  or upon  redemption  or  prepayment  or  otherwise)  shall  be  deemed
abandoned  property  when such  monies or  Governmental  Obligations  shall have
remained  unpaid or  undelivered to the Holder or Holders  entitled  thereto for
three years from the date the principal of the Bonds or any portion  thereof has
become due and payable and shall be subject to the laws of the State of New York
relating to disposition of unclaimed property.

                  SECTION 15.04.  Special Defeasance  Provisions.  The following
provisions  shall be  applicable  to the extent  that a Support  Facility  is in
effect with respect to the Bonds and  compliance  with the following  provisions
are  necessary  to  maintain  the  rating  assigned  to the Bonds as a result of
obtaining such Support Facility.

                  In the event (a) any Bonds are  defeased  pursuant  to Section
15.01 other than during an Auction Rate Period or an Auction  Rate-Inverse  Rate
Period or (b) the purchase  price of Bonds  tendered  for  purchase  pursuant to
Section 5.02 or 5.03 is paid with money supplied by the Company,  the Company on
behalf of the Authority  shall provide (i) an opinion of counsel  experienced in
bankruptcy  matters  acceptable to the Trustee that such deposit will not result
in avoidable  preferential  payments to Bondholders under the Bankruptcy Code as
then in existence or (ii) a Non- Bankruptcy  Certificate with respect to amounts
to be applied to the payment of the Bonds.

<PAGE>



the  calculation  of the Maximum Rate, the Minimum Rate, the Maximum SAVRS Rate,
the Minimum SAVRS Rate or Overdue  Rate, of securities  (whether or not actually
issued) all of which shall have a term as near as  practicable to then effective
Auction Period or Interest  Period or which are subject to optional or mandatory
tender by the owner thereof at the end of a term as near as  practicable to such
Auction  Period or Interest  Period,  the  interest on which is not  included in
gross income for federal income tax purposes,  of no fewer than twenty Component
Issuers selected by the Indexing Agent,  including  issuers of commercial paper,
project notes, bond anticipation notes and tax anticipation  notes,  computed by
the  Indexing  Agent on and as of such  day.  If the Bonds are rated by a Rating
Agency in its highest note or commercial paper rating category or one of its two
highest  long-term debt rating  categories,  each Component Issuer must (a) have
outstanding  securities  rated  by a  Rating  Agency  in  its  highest  note  or
commercial paper rating category or (b) not have outstanding notes or commercial
paper rated by a Rating Agency but have outstanding securities rated by a Rating
Agency in one of its two highest long-term debt rating categories.  If the Bonds
are rated by a Rating Agency in a rating category that is lower than its highest
note or  commercial  paper  rating  category or its two highest  long-term  debt
rating  categories (and the Bonds are not rated in one of such categories by the
other Rating Agency), each Component Issuer must (a) have outstanding securities
rated by a Rating Agency in its note or commercial  paper rating  category which
is the same or correlative,  in the Indexing  Agent's  judgment,  to the note or
commercial  paper rating  category or the long-term debt rating  category of the
Bonds or (b) have  outstanding  securities  rated by a Rating Agency in the same
long-term debt rating  category as the Bonds are rated by that Rating Agency and
not have any outstanding  notes or commercial paper rated by such Rating Agency.
The  Indexing  Agent may change the  Component  Issuers from time to time in its
discretion,  subject to the foregoing requirements.  In addition, at the request
of the  Company and upon  delivery  to the  Trustee  and the Bond  Insurer of an
Opinion of Bond Counsel that such action will not adversely affect the exclusion
of  interest  on the Bonds from gross  income of the owners  thereof for federal
income  tax  purposes,  the  Authority,  with the  consent of the  Company,  may
designate  a new method of setting the Short Term  Tax-Exempt  Rate Index in the
event any of the  above-described  methods are determined by the Authority to be
unavailable,  impracticable  or  unrealistic  in  the  market  place.  Upon  the
occurrence and during the  continuance of a Company  Downgrade  Event,  the Bond
Insurer shall have the right to consent to any change to the  Component  Issuers
and any change in the method of setting  the Short Term  Tax-Exempt  Rate Index,
which consent shall not be unreasonably withheld."

     SECTION  2.09.  Replacement  of the  term  "Lehman  Brothers  Money  Market
     Municipal  Index"  with  the  term   "Short-Term   Tax-Exempt  Rate  Index"
     throughout  the  Indenture.  The Indenture is hereby amended to replace the
     term "Lehman  Brothers Money Market  Municipal  Index" with the term "Short
     Term Tax-Exempt Rate Index" throughout the Indenture.

     SECTION 2.10.  Amendment to the definition of "Potential Holder" in Section
     1.01 of the Indenture. The definition of "Potential Holder" in Section 1.01
     of the  Indenture  is    hereby  amended  to  read  as

               CREDIT  AGREEMENT,  dated as of November 8, 1999,  among  KEYSPAN
CORPORATION,  a New York  corporation  (the  "Borrower"),  the several banks and
other  financial  institutions  or  entities  from time to time  parties to this
Agreement  (the  "Lenders"),  CITIBANK,  N.A., as  syndication  agent,  EUROPEAN
AMERICAN  BANK,  as  Documentation  Agent,  and THE  CHASE  MANHATTAN  BANK,  as
administrative agent.

               The parties hereto hereby agree as follows:

                                    SECTION 1.  DEFINITIONS

                         1.1 Defined Terms. As used in this Agreement, the terms
                    listed  in  this  Section  1.1  shall  have  the  respective
                    meanings set forth in this Section 1.1.

               "ABR":  for any  day,  a rate  per  annum  (rounded  upwards,  if
necessary,  to the next 1/16 of 1%) equal to the  greatest of (a) the Prime Rate
in effect  on such  day,  (b) the Base CD Rate in effect on such day plus 1% and
(c) the Federal Funds  Effective  Rate in effect on such day plus 1/2 of 1%. For
purposes hereof: "Prime Rate" shall mean the rate of interest per annum publicly
announced from time to time by the Reference  Lender as its prime rate in effect
at its principal  office in New York City (the Prime Rate not being  intended to
be the lowest rate of interest  charged by the  Reference  Lender in  connection
with extensions of credit to debtors);  "Base CD Rate" shall mean the sum of (a)
the product of (i) the  Three-Month  Secondary CD Rate and (ii) a fraction,  the
numerator  of which is one and the  denominator  of which is one  minus  the C/D
Reserve  Percentage and (b) the C/D Assessment Rate; and "Three-Month  Secondary
CD Rate" shall mean,  for any day,  the  secondary  market rate for  three-month
certificates of deposit reported as being in effect on such day (or, if such day
shall not be a  Business  Day,  the next  preceding  Business  Day) by the Board
through the public information telephone line of the Federal Reserve Bank of New
York (which rate will, under the current practices of the Board, be published in
Federal Reserve  Statistical  Release  H.15(519)  during the week following such
day),  or,  if such  rate  shall  not be so  reported  on such day or such  next
preceding  Business  Day, the average of the  secondary  market  quotations  for
three-month certificates of deposit of major money center banks in New York City
received at  approximately  10:00 A.M.,  New York City time, on such day (or, if
such day shall not be a Business Day, on the next preceding Business Day) by the
Reference  Lender  from three New York City  negotiable  certificate  of deposit
dealers of  recognized  standing  selected by it. Any change in the ABR due to a
change in the Prime Rate, the Three-Month Secondary CD Rate or the Federal Funds
Effective Rate shall be effective as of the opening of business on the effective
day of such change in the Prime Rate, the  Three-Month  Secondary CD Rate or the
Federal Funds Effective Rate, respectively.

               "ABR Loans":  Loans the rate of interest  applicable  to which is
based upon the ABR.

               "Administrative  Agent": The Chase Manhattan Bank,  together with
its affiliates, as the administrative agent for the Lenders under this Agreement
and the other Loan Documents, together with any of its successors.

               "Affiliate": as to any Person, any other Person that, directly or
indirectly, is in control of, is controlled by, or is under common control with,
such Person.  For purposes of this  definition,  "control" of a Person means the
power, directly or indirectly,  either to (a) vote 10% or more of the securities
having  ordinary  voting  power  for  the  election  of  directors  (or  persons
performing  similar  functions)  of such  Person  or (b)  direct  or  cause  the
direction of the management and policies of such Person,  whether by contract or
otherwise.

               "Aggregate Exposure":  with respect to any Lender at any time, an
amount equal to the amount of such Lender's Commitment then in effect or, if the
Commitments  have been  terminated,  the  amount  of such  Lender's  Loans  then
outstanding.

                         "Aggregate  Exposure  Percentage":  with respect to any
                    Lender at any time, the ratio (expressed as a percentage) of
                    such  Lender's  Aggregate  Exposure  at  such  time  to  the
                    Aggregate Exposure of all Lenders at such time.

                         "Agreement":   this  Credit   Agreement,   as  amended,
                    supplemented or otherwise modified from time to time.

               "Applicable  Margin":  for each Type of Loan,  the rate per annum
set forth under the relevant  column  heading below which  corresponds  with the
most current rating of the Borrower's senior unsecured  long-term debt issued by
S&P and Moody's respectively; provided that for each day the aggregate principal
amount of Loans outstanding is greater than the amount equal to 33% of the Total
Commitments,  the  Applicable  Margin then in effect will be increased by 0.125%
per annum.

==================  =======================  ========================

               Changes in the  Applicable  Margin shall become  effective on the
date on which S&P  and/or  Moody's  changes  the  rating it has  issued  for the
Borrower's senior unsecured  long-term debt. In the event of split ratings,  the
lower of such ratings shall apply;  if only one S&P and Moody's  issues a rating
of the Borrower's senior unsecured long-term debt, such rating shall apply.

               "Approved  Fund":  with respect to any Lender that is a fund that
invests in commercial loans, any other fund that invests in commercial loans and
is managed or advised  by the same  investment  advisor as such  Lender or by an
Affiliate of such investment advisor.

may from time to time be Eurodollar  Loans,  ABR Loans or Competitive  Loans, as

Request  shall  be  confirmed  promptly  by hand  delivery  or  telecopy  to the

time, on the proposed date of such  Competitive  Loan.  Competitive Bids that do
not conform  substantially to the form approved by the Administrative  Agent may
be rejected by the  Administrative  Agent,  and the  Administrative  Agent shall
notify the applicable  Lender as promptly as practicable.  Each  Competitive Bid
shall specify (i) the  principal  amount (which shall be a minimum of $5,000,000
and an integral  multiple of $1,000,000 and which may equal the entire principal
amount of the  Competitive  Loan  requested by the Borrower) of the  Competitive
Loan or Loans that the Lender is willing to make,  (ii) the Competitive Bid Rate
or Rates at which the Lender is prepared  to make such Loan or Loans  (expressed
as a  percentage  rate per annum in the form of a  decimal  to no more than four

the last day thereof.

               (c) The  Administrative  Agent shall promptly notify the Borrower
by telecopy of the  Competitive Bid Rate and the principal  amount  specified in
each  Competitive  Bid and the  identity of the Lender that shall have made such

proposed Competitive  Borrowing,  and in the case of an ABR Loan, not later than
10:30 a.m.,  New York City time, on the proposed date of the  Competitive  Loan;
provided  that (i) the  failure of the  Borrower  to give such  notice  shall be
deemed to be a rejection of each  Competitive  Bid, (ii) the Borrower  shall not
accept  a  Competitive  Bid  made at a  particular  Competitive  Bid Rate if the
Borrower  rejects a Competitive Bid made at a lower  Competitive Bid Rate, (iii)
the aggregate  amount of the Competitive Bids accepted by the Borrower shall not
exceed the aggregate  amount of the requested  Competitive Loan specified in the
related  Competitive  Bid Request,  (iv) to the extent  necessary to comply with
clause  (iii)  above,  the  Borrower  may  accept  Competitive  Bids at the same
Competitive  Bid  Rate in  part,  which  acceptance,  in the  case  of  multiple
Competitive  Bids at such  Competitive  Bid  Rate,  shall  be made  pro  rata in
accordance with the amount of each such Competitive Bid, and (v) except pursuant
to clause (iv) above,  no  Competitive  Bid shall be accepted for a  Competitive
Loan unless such Competitive Loan is in a minimum principal amount of $5,000,000
and an integral  multiple of $1,000,000;  provided further that if a Competitive
Loan must be in an amount  less than  $5,000,000  because of the  provisions  of
clause (iv) above,  such  Competitive Loan may be for a minimum of $1,000,000 or
any integral  multiple  thereof,  and in calculating  the pro rata allocation of
acceptances of portions of multiple Competitive Bids at a

irrevocable.

               (e) The  Administrative  Agent shall promptly notify each bidding
Lender by telecopy whether or not its Competitive Bid has been accepted (and, if
so, the amount and Competitive Bid Rate so accepted), and each successful bidder
will thereupon become bound, subject to the terms and conditions hereof, to make
the Competitive Loan in respect of which its Competitive Bid has been accepted.

               (f)  If  the  Administrative   Agent  shall  elect  to  submit  a
Competitive  Bid in its capacity as a Lender,  it shall submit such  Competitive
Bid  directly to the  Borrower at least one quarter of an hour  earlier than the

Eurodollar  Loans,  $10,000,000  or a whole  multiple  of  $1,000,000  in excess
thereof.  Upon receipt of any such notice from the Borrower,  the Administrative
Agent  shall  promptly  notify each  Lender  thereof.  Each Lender will make the
amount of its pro rata share of each borrowing  available to the  Administrative
Agent for the account of the Borrower at the Funding Office prior to 12:00 Noon,

immediately  available to the Administrative  Agent. Such borrowing will then be
made available to the Borrower by the Administrative Agent crediting the account
of the  Borrower on the books of such office with the  aggregate  of the amounts
made available to the  Administrative  Agent by the Lenders and in like funds as
received by the Administrative Agent.

               2.4 Facility  Fees,  etc.  (a) The Borrower  agrees to pay to the
Administrative  Agent for the  account  of each  Lender a  facility  fee for the
period from and  including  the Closing Date until all of the  Obligations  have

Fee Rate on the  Lender  Percentage  of such  Lender of the total  amount of the
Facility  (drawn or  undrawn),  payable  quarterly in arrears on the last day of

commencing on the first of such dates to occur after the date hereof.

               (b) The Borrower  agrees to pay to the  Administrative  Agent the
fees in the  amounts  and on the dates  previously  agreed to in  writing by the

Commitments  or,  from time to time,  to reduce the  amount of the  Commitments;
provided that no such termination or reduction of Commitments shall be permitted
if, after giving effect thereto and to any  prepayments of the Loans made on the
effective  date  thereof,  the  aggregate  principal  amount  of (i)  the  Loans
outstanding and (ii) any Competitive Loans  outstanding,  would exceed the Total
Commitments.  Any such reduction shall be in an amount equal to $1,000,000, or a
whole multiple  thereof,  and shall reduce  permanently the Commitments  then in
effect.

               2.6 Optional  Prepayments.  The Borrower may at any time and from
time to time prepay the Loans, in whole or in part,  without premium or penalty,

other than the last day of the Interest Period applicable thereto,  the Borrower
shall also pay any amounts owing  pursuant to Section 2.15.  Upon receipt of any
such notice, the Administrative Agent shall promptly notify each Lender thereof.

may elect from time to time to convert ABR Loans to  Eurodollar  Loans by giving
the Administrative  Agent at least three Business Days' prior irrevocable notice
of such election (which notice shall specify the length of the initial  Interest
Period  therefor),  provided that no ABR Loan may be converted into a Eurodollar
Loan  when  any  Event  of  Default  has  occurred  and is  continuing  and  the
Administrative  Agent or the Required  Lenders have  determined  in its or their
sole discretion not to permit such conversions.  Upon receipt of any such notice
the Administrative Agent shall promptly notify each relevant Lender thereof.

               (b)  Any  Eurodollar  Loan  may be  continued  as such  upon  the
expiration  of the then  current  Interest  Period with  respect  thereto by the
Borrower giving irrevocable  notice to the  Administrative  Agent, in accordance
with the  applicable  provisions  of the term  "Interest  Period"  set  forth in
Section 1.1, of the length of the next Interest  Period to be applicable to such
Loans,  provided that no Eurodollar Loan may be continued as such when any Event
of Default has occurred and is continuing  and the  Administrative  Agent has or
the Required  Lenders have  determined  in its or their sole  discretion  not to
permit such  continuations,  and provided,  further,  that if the Borrower shall
fail to give any required notice as described above in this paragraph or if such
continuation is not permitted pursuant to the preceding proviso such Loans shall
be  automatically  converted to ABR Loans on the last day of such then  expiring
Interest Period. Upon receipt of any such notice the Administrative  Agent shall
promptly notify each relevant Lender thereof.

Eurodollar Tranches shall be outstanding at any one time.

               2.9 Interest Rates and Payment Dates.  (a) Each  Eurodollar  Loan
shall bear  interest  for each day during  each  Interest  Period  with  respect
thereto at a rate per annum equal to the Eurodollar Rate determined for such day
plus the Applicable Margin.

               (b) Each ABR Loan shall bear  interest  at a rate per annum equal
to the ABR plus the Applicable Margin.

               (c) Each  Competitive Loan shall bear interest in accordance with
the applicable Competitive Bid Rate.

               (d) (i) If all or a portion of the  principal  amount of any Loan
shall not be paid when due (whether at the stated  maturity,  by acceleration or
otherwise), such overdue amount shall bear interest at a rate per annum equal to
the rate that would  otherwise be applicable  thereto  pursuant to the foregoing
provisions of this Section plus 2%, and (ii) if all or a portion of any interest
payable on any Loan or any facility fee or other amount payable  hereunder shall
not be paid  when due  (whether  at the  stated  maturity,  by  acceleration  or
otherwise), such overdue amount shall bear interest at a rate per annum equal to
the rate then  applicable  to ABR Loans plus 2%, in each case,  with  respect to
clauses (i) and (ii) above,  from the date of such non-payment until such amount
is paid in full.

               (e) Interest shall be payable in arrears on each Interest Payment
Date,  provided that interest accruing pursuant to paragraph (c) of this Section
shall be payable from time to time on demand.

               2.10  Computation  of Interest  and Fees.  (a)  Interest and fees
payable  pursuant  hereto shall be calculated on the basis of a 360-day year for
the actual days  elapsed,  except  that,  with  respect to ABR Loans the rate of
interest on which is  calculated  on the basis of the Prime Rate,  the  interest
thereon shall be calculated on the basis of a 365- (or 366-, as the case may be)
day year for the actual days elapsed.  The Administrative Agent shall as soon as
practicable  notify the Borrower and the relevant Lenders of each  determination
of a Eurodollar Rate. Any change in the interest rate on a Loan resulting from a
change  in  the  ABR or  the  Eurocurrency  Reserve  Requirements  shall  become
effective as of the opening of business on the day on which such change  becomes
effective.  The  Administrative  Agent shall as soon as  practicable  notify the
Borrower and the relevant  Lenders of the effective  date and the amount of each
such change in interest rate.

               (b) Each  determination of an interest rate by the Administrative
Agent  pursuant to any  provision  of this  Agreement  shall be  conclusive  and
binding on the  Borrower and the Lenders in the absence of manifest  error.  The
Administrative  Agent  shall,  at the  request of the  Borrower,  deliver to the
Borrower a statement showing the quotations used by the Administrative  Agent in
determining any interest rate pursuant to Section 2.9(a).

     2.11 Inability to Determine Interest Rate. If prior to the first day of any
Interest Period:

               (a)  the  Administrative   Agent  shall  have  determined  (which
        determination  shall be conclusive and binding upon the Borrower)  that,
        by reason of circumstances affecting the

                                       19




        relevant  market,  adequate  and  reasonable  means  do  not  exist  for
        ascertaining the Eurodollar Rate for such Interest Period,  or that such
        Eurodollar rate is not available; or

               (b) the Administrative  Agent shall have received notice from the
        Required Lenders (or, in the case of a Eurodollar  Competitive Loan, the
        Lender  that is  required  to make such Loan) that the  Eurodollar  Rate
        determined  or to be  determined  for  such  Interest  Period  will  not
        adequately and fairly reflect the cost to such Lenders or Lender, as the
        case may be (as conclusively certified by such Lenders, or Lender as the
        case may be) of making or  maintaining  their affected Loans during such
        Interest Period,

the Administrative Agent shall give telecopy or telephonic notice thereof to the
Borrower and the relevant  Lenders as soon as  practicable  thereafter.  If such
notice is given (w) any Eurodollar  Loans  requested to be made on the first day
of such Interest  Period shall be made as ABR Loans,  (x) any Loans that were to
have been converted on the first day of such Interest Period to Eurodollar Loans
shall be continued as ABR Loans,  (y) any outstanding  Eurodollar Loans shall be
converted, on the last day of the then-current Interest Period, to ABR Loans and
(z) any  request by the  Borrower  for a  Eurodollar  Competitive  Loan shall be
ineffective.  Until such notice has been withdrawn by the Administrative  Agent,
no further  Eurodollar  Loans shall be made or continued as such,  nor shall the
Borrower have the right to convert Loans to Eurodollar Loans.

               2.12 Pro Rata  Treatment and Payments.  (a) Each borrowing by the
Borrower from the Lenders hereunder,  each payment by the Borrower on account of
any facility fee and any  reduction of the  Commitments  of the Lenders shall be
made pro rata according to the respective Lender Percentage of the Lenders.

               (b) Each payment  (including each  prepayment) by the Borrower on
account  of  principal  of and  interest  on the  Loans  shall  be made pro rata
according to the respective outstanding principal amounts of the Loans then held
by the Lenders.

               (c)  All  payments  (including  prepayments)  to be  made  by the
Borrower  hereunder,  whether  on  account  of  principal,   interest,  fees  or
otherwise,  shall be made without setoff or counterclaim and shall be made prior
to 12:00 Noon, New York City time, on the due date thereof to the Administrative
Agent, for the account of the Lenders,  at the Funding Office, in Dollars and in
immediately  available  funds.  The  Administrative  Agent shall distribute such
payments to the Lenders promptly upon receipt in like funds as received.  If any
payment  hereunder (other than payments on the Eurodollar Loans) becomes due and
payable on a day other than a Business  Day,  such payment  shall be extended to
the next  succeeding  Business Day. If any payment on a Eurodollar  Loan becomes
due and payable on a day other than a Business  Day, the maturity  thereof shall
be  extended  to the next  succeeding  Business  Day  unless  the result of such
extension would be to extend such payment into another  calendar month, in which
event such payment shall be made on the immediately  preceding  Business Day. In
the case of any extension of any payment of principal  pursuant to the preceding
two sentences,  interest  thereon shall be payable at the then  applicable  rate
during such extension.

               (d) Unless the  Administrative  Agent shall have been notified in
writing by any Lender  prior to a  borrowing  that such Lender will not make the
amount  that  would  constitute  its share of such  borrowing  available  to the
Administrative  Agent, the  Administrative  Agent may assume that such Lender is
making such amount available to the Administrative Agent, and the Administrative
Agent may, in

509253-0191-02261-99A5F10H-CRA

<PAGE>


                                       20




reliance upon such  assumption,  make available to the Borrower a  corresponding
amount. If such amount is not made available to the Administrative  Agent by the
required  time on the  Borrowing  Date  therefor,  such Lender  shall pay to the
Administrative  Agent,  on demand,  such amount with interest  thereon at a rate
equal to the daily  average  Federal Funds  Effective  Rate for the period until
such Lender makes such amount immediately available to the Administrative Agent.
A certificate of the  Administrative  Agent submitted to any Lender with respect
to any amounts owing under this paragraph  shall be conclusive in the absence of
manifest  error.  If such Lender's share of such borrowing is not made available
to the  Administrative  Agent by such Lender within three  Business Days of such
Borrowing Date, the Administrative  Agent shall also be entitled to recover such
amount with interest  thereon at the rate per annum  applicable to ABR Loans, on
demand, from the Borrower.

               (e) Unless the  Administrative  Agent shall have been notified in
writing by the Borrower  prior to the date of any payment  being made  hereunder
that the Borrower will not make such payment to the  Administrative  Agent,  the
Administrative  Agent may assume that the Borrower is making such  payment,  and
the  Administrative  Agent may, but shall not be required  to, in reliance  upon
such assumption,  make available to the Lenders their respective pro rata shares
of a  corresponding  amount.  If such payment is not made to the  Administrative
Agent by the Borrower  within three  Business  Days of such required  date,  the
Administrative  Agent shall be entitled to recover,  on demand, from each Lender
to which any amount which was made available pursuant to the preceding sentence,
such  amount  with  interest  thereon  at the rate per annum  equal to the daily
average Federal Funds  Effective  Rate.  Nothing herein shall be deemed to limit
the rights of the Administrative Agent or any Lender against the Borrower.

               2.13 Requirements of Law. (a) If the adoption of or any change in
any  Requirement  of Law or in the  interpretation  or  application  thereof  or
compliance  by any Lender with any request or  directive  (whether or not having
the force of law) from any central  bank or other  Governmental  Authority  made
subsequent to the date hereof:

                    (i  shall  subject  any  Lender  to  any  tax  of  any  kind
        whatsoever with respect to this Agreement or any Eurodollar Loan made by
        it, or change  the  basis of  taxation  of  payments  to such  Lender in
        respect thereof (except for  Non-Excluded  Taxes covered by Section 2.14
        and  changes  in the  rate  of tax on the  overall  net  income  of such
        Lender);

                   (ii shall  impose,  modify or hold  applicable  any  reserve,
        special deposit,  compulsory loan or similar  requirement against assets
        held  by,  deposits  or  other  liabilities  in or for the  account  of,
        advances,  loans  or  other  extensions  of  credit  by,  or  any  other
        acquisition of funds by, any office of such Lender that is not otherwise
        included in the determination of the Eurodollar Rate hereunder; or

                  (iii  shall impose on such Lender any other condition;

and the result of any of the  foregoing  is to increase the cost to such Lender,
by an amount that such Lender deems to be material, of making,  converting into,
continuing or maintaining  Eurodollar  Loans, or to reduce any amount receivable
hereunder  in respect  thereof,  then,  in any such  case,  the  Borrower  shall
promptly pay such Lender,  upon its demand,  any additional amounts necessary to
compensate such Lender for such increased cost or reduced amount receivable.  If
any Lender becomes entitled to claim

509253-0191-02261-99A5F10H-CRA

<PAGE>


                                       21




any additional amounts pursuant to this paragraph,  it shall promptly notify the
Borrower  (with a copy to the  Administrative  Agent)  of the event by reason of
which it has become so entitled.

               (b) If any Lender shall have  determined  that the adoption of or
any  change in any  Requirement  of Law  regarding  capital  adequacy  or in the
interpretation  or  application  thereof  or  compliance  by such  Lender or any
corporation  controlling  such Lender with any  request or  directive  regarding
capital adequacy  (whether or not having the force of law) from any Governmental
Authority  made  subsequent to the date hereof shall have the effect of reducing
the  rate  of  return  on  such  Lender's  or such  corporation's  capital  as a
consequence of its obligations hereunder to a level below that which such Lender
or such  corporation  could  have  achieved  but for such  adoption,  change  or
compliance  (taking  into  consideration  such  Lender's  or such  corporation's
policies with respect to capital adequacy) by an amount deemed by such Lender to
be  material,  then from time to time,  after  submission  by such Lender to the
Borrower  (with  a copy  to  the  Administrative  Agent)  of a  written  request
therefor,  the  Borrower  shall pay to such  Lender  such  additional  amount or
amounts as will  compensate  such Lender for such  reduction;  provided that the
Borrower shall not be required to compensate a Lender pursuant to this paragraph
for any amounts incurred more than six months prior to the date that such Lender
notifies the Borrower of such Lender's intention to claim compensation therefor;
and provided further that, if the circumstances giving rise to such claim have a
retroactive  effect, then such six-month period shall be extended to include the
period of such retroactive effect.

               (c) Notwithstanding  the foregoing  provisions of this Section, a
Lender shall not be entitled to compensation pursuant to this Section in respect
of any Competitive  Loan if the Requirement of Law that would otherwise  entitle
it to such compensation  shall have been publicly  announced prior to submission
of the Competitive Bid pursuant to which such Loan was made.

               (d) A certificate as to any additional  amounts payable  pursuant
to this  Section  submitted  by any Lender to the  Borrower  (with a copy to the
Administrative  Agent) shall be conclusive in the absence of manifest error. The
obligations  of  the  Borrower  pursuant  to  this  Section  shall  survive  the
termination of this Agreement and the payment of the Loans and all other amounts
payable hereunder.

               2.14 Taxes.  (a) All  payments  made by the  Borrower  under this
Agreement shall be made free and clear of, and without  deduction or withholding
for or on  account  of,  any  present or future  income,  stamp or other  taxes,
levies,  imposts,  duties,  charges,  fees,  deductions or withholdings,  now or
hereafter imposed, levied,  collected,  withheld or assessed by any Governmental
Authority,  excluding net income taxes and franchise  taxes  (imposed in lieu of
net income taxes) imposed on the Administrative  Agent or any Lender as a result
of a present  or former  connection  between  the  Administrative  Agent or such
Lender and the jurisdiction of the Governmental  Authority  imposing such tax or
any political subdivision or taxing authority thereof or therein (other than any
such  connection  arising  solely from the  Administrative  Agent or such Lender
having  executed,  delivered or performed its  obligations or received a payment
under,  or enforced,  this  Agreement or any other Loan  Document).  If any such
non-excluded  taxes,  levies,  imposts,  duties,  charges,  fees,  deductions or
withholdings  ("Non-Excluded  Taxes") or Other Taxes are required to be withheld
from any amounts payable to the  Administrative  Agent or any Lender  hereunder,
the  amounts so  payable to the  Administrative  Agent or such  Lender  shall be
increased to the extent necessary to yield to the  Administrative  Agent or such
Lender (after  payment of all Non- Excluded  Taxes and Other Taxes)  interest or
any  such  other  amounts  payable  hereunder  at the  rates  or in the  amounts
specified in this Agreement,  provided,  however, that the Borrower shall not be
required to increase any such amounts  payable to any Lender with respect to any
Non-Excluded Taxes (i) that are

509253-0191-02261-99A5F10H-CRA

<PAGE>


                                       22




attributable  to such  Lender's  failure  to  comply  with the  requirements  of
paragraph (d) or (e) of this Section or (ii) that are United States  withholding
taxes imposed on amounts payable to such Lender at the time the Lender becomes a
party to this  Agreement,  except to the extent that such Lender's  assignor (if
any) was entitled, at the time of assignment, to receive additional amounts from
the Borrower with respect to such Non-Excluded Taxes pursuant to this paragraph.

               (b) In addition,  the  Borrower  shall pay any Other Taxes to the
relevant Governmental Authority in accordance with applicable law.

               (c) Whenever any Non-Excluded Taxes or Other Taxes are payable by
the Borrower,  as promptly as possible thereafter the Borrower shall send to the
Administrative  Agent for its own  account or for the  account  of the  relevant
Lender,  as the case may be, a certified  copy of an original  official  receipt
received by the Borrower showing payment  thereof.  If the Borrower fails to pay
any Non-  Excluded  Taxes  or Other  Taxes  when due to the  appropriate  taxing
authority or fails to remit to the Administrative Agent the required receipts or
other  required   documentary   evidence,   the  Borrower  shall  indemnify  the
Administrative  Agent and the Lenders  for any  incremental  taxes,  interest or
penalties that may become payable by the Administrative Agent or any Lender as a
result of any such failure.

               (d) Each Lender (or Transferee) that is not a citizen or resident
of the United  States of America,  a  corporation,  partnership  or other entity
created or  organized  in or under the laws of the United  States of America (or
any  jurisdiction  thereof),  or any  estate or trust that is subject to federal
income  taxation  regardless  of the source of its income (a "Non-U.S.  Lender")
shall deliver to the Borrower and the Administrative Agent (or, in the case of a
Participant,  to the Lender from which the related participation shall have been
purchased) two copies of either U.S.  Internal Revenue Service Form 1001 or Form
4224, or, in the case of a Non-U.S.  Lender claiming exemption from U.S. federal
withholding  tax under  Section  871(h) or  881(c) of the Code with  respect  to
payments  of  "portfolio  interest",  a statement  substantially  in the form of
Exhibit D and a Form W-8,  or any  subsequent  versions  thereof  or  successors
thereto,  properly completed and duly executed by such Non-U.S.  Lender claiming
complete  exemption from, or a reduced rate of, U.S. federal  withholding tax on
all payments by the Borrower under this Agreement and the other Loan  Documents.
Such forms shall be delivered by each  Non-U.S.  Lender on or before the date it
becomes a party to this  Agreement  (or, in the case of any  Participant,  on or
before  the date such  Participant  purchases  the  related  participation).  In
addition,  each  Non-U.S.  Lender  shall  deliver such forms  promptly  upon the
obsolescence  or  invalidity of any form  previously  delivered by such Non-U.S.
Lender.  Each Non-U.S.  Lender shall promptly notify the Borrower at any time it
determines  that  it is no  longer  in a  position  to  provide  any  previously
delivered  certificate  to the  Borrower  (or any  other  form of  certification
adopted by the U.S. taxing  authorities for such purpose).  Notwithstanding  any
other  provision of this paragraph,  a Non-U.S.  Lender shall not be required to
deliver any form pursuant to this  paragraph  that such  Non-U.S.  Lender is not
legally able to deliver.

               (e) A Lender that is entitled to an  exemption  from or reduction
of  non-U.S.  withholding  tax  under the law of the  jurisdiction  in which the
Borrower is located,  or any treaty to which such  jurisdiction is a party, with
respect to payments under this  Agreement  shall deliver to the Borrower (with a
copy to the Administrative Agent), at the time or times prescribed by applicable
law or  reasonably  requested  by the  Borrower,  such  properly  completed  and
executed documentation prescribed by applicable law as will permit such payments
to be made without  withholding or at a reduced rate,  provided that such Lender
is legally entitled to complete, execute and deliver such documentation and in

509253-0191-02261-99A5F10H-CRA

<PAGE>


                                       23




such  Lender's  judgment  such  completion,  execution or  submission  would not
materially prejudice the legal position of such Lender.

               (f) The agreements in this Section shall survive the  termination
of this  Agreement  and the payment of the Loans and all other  amounts  payable
hereunder.

               2.15 Indemnity.  The Borrower agrees to indemnify each Lender and
to hold each  Lender  harmless  from any loss or  expense  that such  Lender may
sustain or incur as a  consequence  of (a)  default by the  Borrower in making a
borrowing of,  conversion  into or  continuation  of Eurodollar  Loans after the
Borrower  has  given a  notice  requesting  the  same  in  accordance  with  the
provisions  of this  Agreement,  (b)  default  by the  Borrower  in  making  any
prepayment of or conversion from Eurodollar Loans after the Borrower has given a
notice  thereof in accordance  with the  provisions of this  Agreement,  (c) the
making of a prepayment of Eurodollar  Loans on a day that is not the last day of
an Interest  Period with respect  thereto or (d) the making of a prepayment of a
Competitive  Loan.  Such  indemnification  may  include  an amount  equal to the
excess,  if any,  of (i) the amount of interest  that would have  accrued on the
amount so prepaid,  or not so borrowed,  converted or continued,  for the period
from the date of such  prepayment  or of such  failure  to  borrow,  convert  or
continue to the last day of such  Interest  Period (or, in the case of a failure
to borrow, convert or continue, the Interest Period that would have commenced on
the date of such  failure) in each case at the  applicable  rate of interest for
such Loans  provided  for herein  (excluding,  however,  the  Applicable  Margin
included  therein,  if any) over  (ii) the  amount of  interest  (as  reasonably
determined by such Lender) that would have accrued to such Lender on such amount
by placing such amount on deposit for a comparable  period with leading banks in
the  interbank  eurodollar  market.  A  certificate  as to any  amounts  payable
pursuant  to this  Section  submitted  to the  Borrower  by any Lender  shall be
conclusive in the absence of manifest  error.  This  covenant  shall survive the
termination of this Agreement and the payment of the Loans and all other amounts
payable hereunder.

               2.16 Change of Lending Office.  Each Lender agrees that, upon the
occurrence  of any event giving rise to the operation of Section 2.13 or 2.14(a)
with  respect  to such  Lender,  it will,  if  requested  by the  Borrower,  use
reasonable efforts (subject to overall policy  considerations of such Lender) to
designate  another  lending office for any Loans affected by such event with the
object  of  avoiding  the  consequences  of  such  event;  provided,  that  such
designation  is made on terms that, in the sole  judgment of such Lender,  cause
such Lender and its lending office(s) to suffer no economic, legal or regulatory
disadvantage,  and provided,  further, that nothing in this Section shall affect
or postpone any of the  obligations  of any Borrower or the rights of any Lender
pursuant to Section 2.13 or 2.14(a).

               2.17  Replacement of Lenders.  The Borrower shall be permitted to
replace any Lender that (a) requests reimbursement for amounts owing pursuant to
Section  2.13 or  2.14(a)  or (b)  defaults  in its  obligation  to  make  Loans
hereunder,  with a  replacement  financial  institution;  provided that (i) such
replacement  does not conflict  with any  Requirement  of Law,  (ii) no Event of
Default shall have  occurred and be continuing at the time of such  replacement,
(iii)  prior to any such  replacement,  such  Lender  shall have taken no action
under Section 2.16 so as to eliminate the continued  need for payment of amounts
owing  pursuant  to Section  2.13 or  2.14(a),  (iv) the  replacement  financial
institution  shall  purchase,  at par, all Loans and other amounts owing to such
replaced Lender on or prior to the date of  replacement,  (v) the Borrower shall
be liable to such replaced  Lender under Section 2.15 if any Eurodollar  Loan or
Eurodollar  Competitive  Loan owing to such  replaced  Lender shall be purchased
other than on the last day of the Interest  Period  relating  thereto,  (vi) the
replacement financial institution, if not already a Lender, shall be

509253-0191-02261-99A5F10H-CRA

<PAGE>


                                       24




reasonably  satisfactory to the Administrative  Agent, (vii) the replaced Lender
shall be obligated to make such replacement in accordance with the provisions of
Section  9.6  (provided  that  the  Borrower  shall  be  obligated  to  pay  the
registration and processing fee referred to therein),  (viii) until such time as
such  replacement  shall be  consummated,  the Borrower shall pay all additional
amounts (if any) required  pursuant to Section 2.13 or 2.14(a),  as the case may
be,  and (ix) any such  replacement  shall  not be  deemed to be a waiver of any
rights that the  Borrower,  the  Administrative  Agent or any other Lender shall
have against the replaced Lender.

                          SECTION 3.  REPRESENTATIONS AND WARRANTIES

               To induce the Administrative  Agent and the Lenders to enter into
this  Agreement  and to make the  Loans,  the  Borrower  hereby  represents  and
warrants to the Administrative Agent and each Lender that:

               3.1   Financial   Condition.   The   audited   consolidated   and
unconsolidated  balance sheets of the Borrower as at March 31, 1998 and December
31, 1998, and the related  consolidated and unconsolidated  statements of income
and of cash flows for the fiscal  years ended on such dates,  reported on by and
accompanied  by an  unqualified  report from Ernst & Young and Arthur  Andersen,
respectively,  present  fairly the  consolidated  and  unconsolidated  financial
condition  of  the  Borrower  as  at  such  date,  and  the   consolidated   and
unconsolidated results of its operations and its consolidated and unconsolidated
cash  flows  for  the  respective   fiscal  years  then  ended.   The  unaudited
consolidated  and  unconsolidated  balance  sheet of the Borrower as at June 30,
1999, and the related unaudited  consolidated and  unconsolidated  statements of
income  and cash flows for the  six-month  period  ended on such  date,  present
fairly the consolidated and unconsolidated  financial  condition of the Borrower
as at  such  date,  and  the  consolidated  and  unconsolidated  results  of its
operations and its consolidated  cash flows for the six- month period then ended
(subject to normal year-end audit adjustments).  All such financial  statements,
including  the  related  schedules  and notes  thereto,  have been  prepared  in
accordance  with GAAP  applied  consistently  throughout  the  periods  involved
(except as approved by the  aforementioned  firm of  accountants  and  disclosed
therein).  The Borrower and its Subsidiaries do not have any material  Guarantee
Obligations,  contingent liabilities and liabilities for taxes, or any long-term
leases or unusual forward or long-term commitments,  including any interest rate
or foreign currency swap or exchange  transaction or other obligation in respect
of derivatives,  that are not reflected in the most recent financial  statements
referred to in this paragraph,  except Guarantee  Obligations of Indebtedness of
the  Borrower  and/or any of its  Subsidiaries  so long as the  Indebtedness  in
respect of which such Guarantee Obligations arise is reflected in such financial
statements.  During  the period  from June 30,  1999 to and  including  the date
hereof there has been no Disposition by the Borrower of any material part of its
business or property.

     3.2 No Change.  Since  December 31, 1998 there has been no  development  or
event that has had or could  reasonably  be expected to have a Material  Adverse
Effect.

               3.3  Corporate  Existence;  Compliance  with  Law.  Each  of  the
Borrower  and  its  Significant  Subsidiaries  (a) is  duly  organized,  validly
existing  and in  good  standing  under  the  laws  of the  jurisdiction  of its
organization, (b) has the corporate power and authority, and the legal right, to
own and operate its property, to lease the property it operates as lessee and to
conduct the business in which it is currently engaged,  (c) is duly qualified as
a foreign  corporation and in good standing under the laws of each  jurisdiction
where its  ownership,  lease or  operation  of  property  or the  conduct of its
business

requires such  qualification  and (d) is in compliance with all  Requirements of
Law except to the extent that the failure to comply  therewith could not, in the
aggregate, reasonably be expected to have a Material Adverse Effect.

               3.4 Corporate Power; Authorization;  Enforceable Obligations. The
Borrower has the corporate  power and authority,  and the legal right,  to make,
deliver and perform the Loan Documents and to borrow hereunder. The Borrower has
taken all necessary  corporate  action to authorize the execution,  delivery and
performance  of the Loan  Documents and to authorize the borrowings on the terms
and conditions of this Agreement.  No consent or authorization  of, filing with,
notice to or other act by or in respect of, any  Governmental  Authority  or any
other Person is required in connection with the borrowings hereunder or with the
execution, delivery,  performance,  validity or enforceability of this Agreement
or any of the Loan  Documents,  except  consents,  authorizations,  filings  and
notices described in Schedule 3.4, which consents,  authorizations,  filings and
notices have been  obtained or made and are in full force and effect.  Each Loan
Document has been duly executed and  delivered on behalf of the  Borrower.  This
Agreement  constitutes,  and  each  other  Loan  Document  upon  execution  will
constitute,  a legal, valid and binding obligation of the Borrower,  enforceable
against the Borrower in accordance with its terms,  except as enforceability may
be limited by applicable bankruptcy, insolvency,  reorganization,  moratorium or
similar laws  affecting the  enforcement of creditors'  rights  generally and by
general equitable  principles  (whether  enforcement is sought by proceedings in
equity or at law).

               3.5 No Legal Bar. The execution, delivery and performance of this
Agreement and the other Loan Documents,  the borrowings hereunder and the use of
the proceeds  thereof will not violate any Requirement of Law or any Contractual
Obligation of the Borrower or any of its Subsidiaries and will not result in, or
require,  the  creation  or  imposition  of any Lien on any of their  respective
properties  or  revenues  pursuant  to  any  Requirement  of  Law  or  any  such
Contractual  Obligation.   No  Requirement  of  Law  or  Contractual  Obligation
applicable  to the  Borrower  or any of its  Subsidiaries  could  reasonably  be
expected to have a Material Adverse Effect.

               3.6 Litigation. No litigation,  investigation or proceeding of or
before any arbitrator or Governmental  Authority is pending or, to the knowledge
of  the  Borrower,  threatened  by  or  against  the  Borrower  or  any  of  its
Subsidiaries or against any of their respective  properties or revenues (a) with
respect to any of the Loan  Documents  or any of the  transactions  contemplated
hereby or thereby,  or (b) that could  reasonably be expected to have a Material
Adverse Effect.

               3.7 No Default.  Neither the Borrower nor any of its Subsidiaries
is in default under or with respect to any of its Contractual Obligations in any
respect that could reasonably be expected to have a Material Adverse Effect.  No
Default or Event of Default has occurred and is continuing.

               3.8  Ownership of Property;  Liens.  Each of the Borrower and its
Subsidiaries  has title in fee simple to, or a valid leasehold  interest in, all
its real property,  and good title to, or a valid leasehold interest in, all its
other  property,  except to the  extent  failure  to have such  title  could not
reasonably  be  expected  to have a Material  Adverse  Effect,  and none of such
property is subject to any Lien except as permitted by Section 6.2.

               3.9  Intellectual   Property.   The  Borrower  and  each  of  its
Subsidiaries  owns, or is licensed to use, all Intellectual  Property  necessary
for the conduct of its  business as  currently  conducted,  except to the extent
failure to have such  ownership or license  could not  reasonably be expected to
have a Material

509253-0191-02261-99A5F10H-CRA

<PAGE>


                                       26




Adverse Effect. No material claim has been asserted and is pending by any Person
challenging or questioning the use of any Intellectual  Property or the validity
or  effectiveness of any  Intellectual  Property,  except to the extent any such
claim could not reasonably be expected to have a Material  Adverse  Effect,  nor
does  the  Borrower  know of any  valid  basis  for any such  claim.  The use of
Intellectual  Property by the Borrower and its Subsidiaries does not infringe on
the rights of any Person in any material respect,  except to the extent any such
infringement could not reasonably be expected to have a Material Adverse Effect.

               3.10 Taxes. Each of the Borrower and each of its Subsidiaries has
filed or caused to be filed all  Federal,  state and other  material tax returns
that are required to be filed and has paid all taxes shown to be due and payable
on said returns or on any assessments made against it or any of its property and
all other taxes,  fees or other charges  imposed on it or any of its property by
any  Governmental  Authority  (other than any the amount or validity of that are
currently  being  contested in good faith by  appropriate  proceedings  and with
respect to which  reserves  in  conformity  with GAAP have been  provided on the
books of the Borrower or its Subsidiaries,  as the case may be); no material tax
Lien has been filed, and, to the knowledge of the Borrower, no material claim is
being asserted, with respect to any such tax, fee or other charge.

               3.11  Federal  Regulations.  No part of the proceeds of any Loans
will be used for "buying" or "carrying" any "margin stock" within the respective
meanings of each of the quoted terms under  Regulation U as now and from time to
time  hereafter in effect or for any purpose that violates the provisions of the
Regulations of the Board.

               3.12  Labor  Matters.  Except  as,  in the  aggregate,  could not
reasonably  be  expected  to have a Material  Adverse  Effect:  (a) there are no
strikes or other labor disputes  against the Borrower or any of its Subsidiaries
pending or, to the  knowledge of the Borrower,  threatened;  (b) hours worked by
and payment made to employees of the Borrower and its Subsidiaries have not been
in violation of the Fair Labor Standards Act or any other applicable Requirement
of Law dealing with such matters;  and (c) all payments due from the Borrower or
any of its Subsidiaries on account of employee health and welfare insurance have
been paid or accrued as a liability on the books of the Borrower or the relevant
Subsidiary.

               3.13  ERISA.  Neither  a  Reportable  Event  nor an  "accumulated
funding  deficiency"  (within  the meaning of Section 412 of the Code or Section
302 of ERISA) has  occurred  during the  five-year  period  prior to the date on
which this  representation  is made or deemed made with respect to any Plan, and
each Plan has complied in all material  respects with the applicable  provisions
of ERISA and the Code. No  termination  of a Single  Employer Plan has occurred,
and no Lien in favor of the PBGC or a Plan has  arisen,  during  such  five-year
period.  The present value of all accrued  benefits  under each Single  Employer
Plan  (based on those  assumptions  used to fund such  Plans) did not, as of the
last annual  valuation  date prior to the date on which this  representation  is
made or deemed  made,  exceed the value of the assets of such Plan  allocable to
such  accrued  benefits  by a material  amount.  Neither  the  Borrower  nor any
Commonly  Controlled  Entity has had a complete or partial  withdrawal  from any
Multiemployer  Plan that has resulted or could  reasonably be expected to result
in a material  liability under ERISA,  and neither the Borrower nor any Commonly
Controlled Entity would become subject to any material  liability under ERISA if
the Borrower or any such Commonly  Controlled Entity were to withdraw completely
from all Multiemployer Plans as of the valuation date most closely preceding the
date on

509253-0191-02261-99A5F10H-CRA

                                       27




     which this  representation  is made or deemed made.  No such  Multiemployer
Plan is in Reorganization or Insolvent.

               3.14  Investment  Company  Act;  Other  Regulations.  Neither the
Borrower  nor  any of its  Subsidiaries  is (i) an  "investment  company",  or a
company  "controlled"  by an  "investment  company",  within the  meaning of the
Investment  Company Act of 1940. The Borrower and each of its  Subsidiaries  are
exempt from registration as a "holding company" under the Public Utility Holding
Company  Act  of  1935,  as  amended.  Neither  the  Borrower  nor  any  of  its
Subsidiaries  is subject to regulation  under any Requirement of Law (other than
Regulation X of the Board) that limits its ability to incur Indebtedness.

               3.15  Subsidiaries.  Except as  disclosed  to the  Administrative
Agent by the Borrower in writing from time to time after the Closing  Date,  (a)
Schedule  3.15 sets forth the name and  jurisdiction  of  incorporation  of each
Significant  Subsidiary and, as to each such Subsidiary,  the percentage of each
class of Capital  Stock owned by the Borrower  and (b) there are no  outstanding
subscriptions,   options,   warrants,  calls,  rights  or  other  agreements  or
commitments  (other than stock  options  granted to employees  or directors  and
directors' qualifying shares) of any nature relating to any Capital Stock of the
Borrower or any Significant Subsidiary, except as created by the Loan Documents.

               3.16 Use of Proceeds. The proceeds of the Loans shall be used for
general corporate purposes (including commercial paper back-up liquidity) of the
Borrower and its Subsidiaries in the ordinary course of business.

     3.17  Environmental  Matters.  Except  as,  in  the  aggregate,  could  not
reasonably be expected to have a Material Adverse Effect:

               (a) the facilities and  properties  owned,  leased or operated by
        the  Borrower  or any  of its  Subsidiaries  (the  "Properties")  do not
        contain,   and  have  not   previously   contained,   any  Materials  of
        Environmental   Concern   in   amounts   or   concentrations   or  under
        circumstances  that  constitute or  constituted a violation of, or could
        give rise to liability under, any Environmental Law;

               (b) neither the Borrower nor any of its Subsidiaries has received
        or  is  aware  of  any   notice   of   violation,   alleged   violation,
        non-compliance, liability or potential liability regarding environmental
        matters or compliance with  Environmental Laws with regard to any of the
        Properties  or  the  business  operated  by the  Borrower  or any of its
        Subsidiaries (the  "Business"),  nor does the Borrower have knowledge or
        reason to believe  that any such  notice  will be  received  or is being
        threatened;

               (c) Materials of Environmental  Concern have not been transported
        or disposed of from the Properties in violation of, or in a manner or to
        a location that could give rise to liability  under,  any  Environmental
        Law, nor have any  Materials of  Environmental  Concern been  generated,
        treated,  stored or disposed of at, on or under any of the Properties in
        violation  of, or in a manner that could give rise to  liability  under,
        any applicable Environmental Law;

               (d) no judicial  proceeding  or  governmental  or  administrative
        action is pending  or, to the  knowledge  of the  Borrower,  threatened,
        under any  Environmental  Law to which the Borrower or any Subsidiary is
        or will be  named  as a party  with  respect  to the  Properties  or the
        Business,  nor are there any consent  decrees or other decrees,  consent
        orders, administrative orders or other

509253-0191-02261-99A5F10H-CRA

                                       28




     orders, or other administrative or judicial requirements  outstanding under
any Environmental Law with respect to the Properties or the Business;

               (e) there has been no release  or threat of release of  Materials
        of Environmental  Concern at or from the Properties,  or arising from or
        related  to  the  operations  of  the  Borrower  or  any  Subsidiary  in
        connection  with the  Properties  or  otherwise in  connection  with the
        Business,  in  violation of or in amounts or in a manner that could give
        rise to liability under Environmental Laws;

               (f) the  Properties  and all  operations at the Properties are in
        compliance, and have in the last five years been in compliance, with all
        applicable  Environmental  Laws, and there is no contamination at, under
        or about the  Properties  or  violation  of any  Environmental  Law with
        respect to the Properties or the Business; and

               (g) neither the Borrower nor any of its  Subsidiaries has assumed
        any liability of any other Person under Environmental Laws.

               3.18 Accuracy of  Information,  etc. No statement or  information
contained in this Agreement,  the Notes, the Confidential Information Memorandum
or any other document, certificate or statement furnished by or on behalf of the
Borrower to the Administrative  Agent or the Lenders, or any of them, for use in
connection with the transactions contemplated by this Agreement, contained as of
the date such statement,  information,  document or certificate was so furnished
(or, in the case of the Confidential  Information Memorandum,  as of the date of
this  Agreement),  any untrue statement of a material fact or omitted to state a
material fact necessary to make the statements  contained  herein or therein not
misleading.  There is no fact known to the  Borrower  that could  reasonably  be
expected to have a Material Adverse Effect that has not been expressly disclosed
herein,  in the Confidential  Information  Memorandum or in any other documents,
certificates  and  statements  furnished  to the  Administrative  Agent  and the
Lenders for use in connection with the transactions contemplated hereby.

               3.19 Year 2000 Matters. Any reprogramming  required to permit the
proper  functioning (but only to the extent that such proper  functioning  would
otherwise be impaired by the  occurrence  of the year 2000) in and following the
year  2000  of  computer  systems  and  other  equipment   containing   embedded
microchips,  in either  case owned or  operated  by the  Borrower  or any of its
Subsidiaries or used or relied upon in the conduct of their business  (including
any such  systems  and other  equipment  supplied  by  others or with  which the
computer systems of the Borrower or any of its Subsidiaries interface),  and the
testing of all such  systems and other  equipment as so  reprogrammed,  has been
completed.  The costs to the  Borrower and its  Subsidiaries  that have not been
incurred as of the date hereof for reasonably  foreseeable  consequences to them
of any improper  functioning of other computer systems and equipment  containing
embedded  microchips due to the occurrence of the year 2000 could not reasonably
be  expected  to result in a Default  or Event of  Default or to have a Material
Adverse Effect.  Except for any  reprogramming  referred to above,  the computer
systems of the Borrower  and its  Subsidiaries  are and,  with  ordinary  course
upgrading and  maintenance,  will continue for the term of this Agreement to be,
sufficient for the conduct of their business as currently conducted.

               4.1 Conditions to Initial  Extension of Credit.  The agreement of

        amounts thereunder shall have been paid in full.

               (c)  Financial  Statements.  The Lenders  shall have received (i)

        applicable financial statements delivered pursuant to clause (i) of this
        paragraph as to which such financial statements are available,  and such
        financial  statements  shall  not,  in the  reasonable  judgment  of the

        financial  condition of the  Borrower,  as  reflected  in the  financial
        statements  or  projections  contained in the  Confidential  Information
        Memorandum.

               (d)  Approvals.   All  governmental  and  third  party  approvals

        of Exhibit C. Such legal opinion shall cover such other matters incident
        to the transactions contemplated by this Agreement as the Administrative
        Agent may reasonably require.

               (h) The Borrower  shall have received a rating of its  commercial

               4.2 Conditions to Each Extension of Credit. The agreement of each
Lender to make any  extension  of credit  requested to be made by it on any date
(including its initial  extension of credit) is subject to the  satisfaction  of
the following conditions precedent:

               (a) Representations  and Warranties.  Each of the representations
        and  warranties  made by the  Borrower in or pursuant to this  Agreement
        shall be true and correct on and as of such date as if made on and as of
        such date.

               (b) No  Default.  No  Default  or Event  of  Default  shall  have
        occurred and be  continuing  on such date or after giving  effect to the
        extensions of credit requested to be made on such date.

Each borrowing by the Borrower  hereunder shall constitute a representation  and
warranty  by the  Borrower as of the date of such  extension  of credit that the
conditions contained in this Section 4.2 have been satisfied.

                               SECTION 5.  AFFIRMATIVE COVENANTS

               The  Borrower  hereby  agrees  that,  so long as the  Commitments
remain  in  effect  or any Loan or other  amount  is owing to any  Lender or the
Administrative  Agent hereunder,  the Borrower shall and shall cause each of its
Subsidiaries to:

     5.1  Financial  Statements.  Furnish to the  Administrative  Agent and each
Lender:

               (a) as soon as available,  but in any event within 120 days after
        the  end of each  fiscal  year of the  Borrower,  a copy of the  audited
        consolidated   balance  sheet  of  the  Borrower  and  its  consolidated
        Subsidiaries  as at the end of such fiscal year and the related  audited
        consolidated  statements  of income  and of cash  flows for such  fiscal
        year, setting forth in each case in comparative form the figures for the
        previous  fiscal  year,  reported  on without a "going  concern" or like
        qualification or exception, or qualification arising out of the scope of
        the audit,  by Arthur  Andersen or other  independent  certified  public
        accountants of nationally recognized standing; and

               (b) as soon as available, but in any event not later than 60 days
        after  the end of each of the  first  three  quarterly  periods  of each
        fiscal year of the Borrower, the unaudited consolidated balance sheet of
        the Borrower  and its  consolidated  Subsidiaries  as at the end of such
        quarter and the related unaudited consolidated  statements of income and

        Responsible  Officer as being  fairly  stated in all  material  respects

respects and shall be prepared in reasonable  detail and in accordance with GAAP
applied  consistently  throughout the periods  reflected  therein and with prior
periods (except as approved by such accountants or officer,  as the case may be,
and disclosed therein).

        the Borrower  during such period has  observed or  performed  all of its
        covenants and other agreements, and satisfied every condition, contained
        in this Agreement to be observed, performed or satisfied by it, and that
        such  Responsible  Officer has  obtained no  knowledge of any Default or

        case  of  quarterly  or  annual  financial   statements,   a  compliance

               (b)  within  five days  after  the same are  sent,  copies of all
        financial  statements and reports that the Borrower sends to the holders
        of any class of its debt  securities  or public equity  securities  and,

proceedings  and reserves in conformity with GAAP with respect thereto have been
provided on the books of the Borrower or its Subsidiaries, as the case may be or
(ii) the  failure to do so could not  reasonably  be expected to have a Material
Adverse Effect.

               5.4 Maintenance of Existence;  Compliance. (a) In the case of the

other Loan Document (except to the extent that any of the foregoing are found by
a final and nonappealable  decision of a court of competent jurisdiction to have
resulted from its or such Person's own gross  negligence or willful  misconduct)
or (ii)  responsible  in any  manner  to any of the  Lenders  for any  recitals,
statements,  representations  or warranties  made by the Borrower or any officer
thereof  contained  in this  Agreement  or any  other  Loan  Document  or in any
certificate, report, statement or other document referred to or provided for in,
or  received  by the  Administrative  Agent under or in  connection  with,  this
Agreement or

                                       38




any other Loan Document or for the value, validity, effectiveness,  genuineness,
enforceability  or  sufficiency  of this Agreement or any other Loan Document or
for any  failure  of the  Borrower  to  perform  its  obligations  hereunder  or
thereunder.  The  Administrative  Agent shall not be under any obligation to any
Lender to ascertain or to inquire as to the  observance or performance of any of
the agreements  contained in, or conditions of, this Agreement or any other Loan
Document, or to inspect the properties, books or records of the Borrower.

               8.4 Reliance by Administrative  Agent. The  Administrative  Agent
shall be entitled to rely,  and shall be fully  protected  in relying,  upon any
instrument,  writing,  resolution,  notice,  consent,  certificate,   affidavit,
letter, telecopy, telex or teletype message,  statement, order or other document
or  conversation  believed  by it to be  genuine  and  correct  and to have been
signed,  sent or made by the  proper  Person  or  Persons  and upon  advice  and
statements of legal counsel  (including  counsel to the  Borrower),  independent
accountants  and  other  experts  selected  by  the  Administrative  Agent.  The
Administrative  Agent  may deem and  treat  the  payee of any Note as the  owner
thereof for all purposes  unless a written notice of assignment,  negotiation or
transfer  thereof  shall  have been  filed with the  Administrative  Agent.  The
Administrative Agent shall be fully justified in failing or refusing to take any
action  under this  Agreement or any other Loan  Document  unless it shall first
receive such advice or concurrence of the Required  Lenders (or, if so specified
by this  Agreement,  all Lenders) as it deems  appropriate  or it shall first be
indemnified to its satisfaction by the Lenders against any and all liability and
expense that may be incurred by it by reason of taking or continuing to take any
such action. The  Administrative  Agent shall in all cases be fully protected in
acting,  or in refraining  from acting,  under this Agreement and the other Loan
Documents  in  accordance  with a request of the  Required  Lenders  (or,  if so
specified by this Agreement, all Lenders), and such request and any action taken
or failure to act pursuant thereto shall be binding upon all the Lenders and all
future holders of the Loans.

               8.5 Notice of  Default.  The  Administrative  Agent  shall not be
deemed to have  knowledge or notice of the occurrence of any Default or Event of
Default  hereunder  unless the  Administrative  Agent has received notice from a
Lender or the Borrower  referring to this Agreement,  describing such Default or
Event of Default and stating that such notice is a "notice of  default".  In the
event that the  Administrative  Agent receives such a notice, the Administrative
Agent shall give notice thereof to the Lenders.  The Administrative  Agent shall
take such  action with  respect to such  Default or Event of Default as shall be
reasonably  directed  by the  Required  Lenders  (or,  if so  specified  by this
Agreement, all Lenders); provided that unless and until the Administrative Agent
shall have received such directions, the Administrative Agent may (but shall not
be  obligated  to) take such action,  or refrain  from taking such action,  with
respect to such  Default or Event of Default as it shall deem  advisable  in the
best interests of the Lenders.

               8.6 Non-Reliance on Administrative Agent and Other Lenders.  Each
Lender expressly  acknowledges that neither the Administrative  Agent nor any of
its officers, directors, employees, agents, attorneys-in-fact or affiliates have
made  any   representations  or  warranties  to  it  and  that  no  act  by  the
Administrative  Agent hereinafter taken,  including any review of the affairs of
the Borrower or any affiliate of the Borrower, shall be deemed to constitute any
representation  or warranty  by the  Administrative  Agent to any  Lender.  Each
Lender  represents to the  Administrative  Agent that it has,  independently and
without reliance upon the Administrative Agent or any other Lender, and based on
such  documents  and  information  as it has  deemed  appropriate,  made its own
appraisal  of  and  investigation  into  the  business,  operations,   property,
financial  and other  condition  and  creditworthiness  of the  Borrower and its
affiliates and made its own decision to make its Loans hereunder and enter into

509253-0191-02261-99A5F10H-CRA

<PAGE>


                                       39




this  Agreement.  Each Lender also represents  that it will,  independently  and
without reliance upon the Administrative Agent or any other Lender, and based on
such  documents  and  information  as it shall  deem  appropriate  at the  time,
continue to make its own credit analysis,  appraisals and decisions in taking or
not taking action under this Agreement and the other Loan Documents, and to make
such  investigation  as it deems  necessary to inform itself as to the business,
operations,  property, financial and other condition and creditworthiness of the
Borrower and its  affiliates.  Except for notices,  reports and other  documents
expressly  required to be furnished to the Lenders by the  Administrative  Agent
hereunder, the Administrative Agent shall not have any duty or responsibility to
provide any Lender with any credit or other information concerning the business,
operations,   property,   condition  (financial  or  otherwise),   prospects  or
creditworthiness  of the Borrower or any affiliate of the Borrower that may come
into  the  possession  of the  Administrative  Agent  or  any  of its  officers,
directors, employees, agents, attorneys-in-fact or affiliates.

               8.7   Indemnification.   The  Lenders   agree  to  indemnify  the
Administrative  Agent in its capacity as such (to the extent not  reimbursed  by
the Borrower  and without  limiting  the  obligation  of the Borrower to do so),
ratably according to their respective  Aggregate Exposure  Percentages in effect
on the date on which  indemnification  is sought  under  this  Section  (or,  if
indemnification  is sought after the date upon which the Commitments  shall have
terminated  and the Loans  shall have been paid in full,  ratably in  accordance
with such Aggregate Exposure  Percentages  immediately prior to such date), from
and against any and all liabilities,  obligations,  losses, damages,  penalties,
actions,  judgments,  suits,  costs,  expenses  or  disbursements  of  any  kind
whatsoever  that may at any time  (whether  before or after the  payment  of the
Loans) be imposed on, incurred by or asserted against the  Administrative  Agent
in any way relating to or arising out of, the Commitments,  this Agreement,  any
of the other Loan  Documents  or any  documents  contemplated  by or referred to
herein or  therein  or the  transactions  contemplated  hereby or thereby or any
action taken or omitted by the Administrative  Agent under or in connection with
any of the foregoing; provided that no Lender shall be liable for the payment of
any  portion  of such  liabilities,  obligations,  losses,  damages,  penalties,
actions,  judgments, suits, costs, expenses or disbursements that are found by a
final and  nonappealable  decision of a court of competent  jurisdiction to have
resulted from the Administrative Agent's gross negligence or willful misconduct.
The  agreements  in this Section  shall survive the payment of the Loans and all
other amounts payable hereunder.

               8.8  Administrative  Agent  in  Its  Individual   Capacity.   The
Administrative  Agent and its affiliates may make loans to, accept deposits from
and  generally  engage in any kind of business  with the  Borrower as though the
Administrative Agent was not the Administrative Agent. With respect to its Loans
made or renewed by it, the  Administrative  Agent shall have the same rights and
powers under this  Agreement and the other Loan  Documents as any Lender and may
exercise the same as though it were not the Administrative  Agent, and the terms
"Lender" and "Lenders" shall include the Administrative  Agent in its individual
capacity.

               8.9 Successor  Administrative Agent. The Administrative Agent may
resign as  Administrative  Agent  upon 30 days'  notice to the  Lenders  and the
Borrower. If the Administrative Agent shall resign as Administrative Agent under
this Agreement, then the Required Lenders shall appoint from among the Lenders a
successor agent for the Lenders, which successor agent shall (unless an Event of
Default  under  Section 7(a) or Section 7(f) with respect to the Borrower  shall
have occurred and be continuing)  be subject to approval by the Borrower  (which
approval  shall  not  be  unreasonably  withheld  or  delayed),  whereupon  such
successor  agent  shall  succeed  to  the  rights,  powers  and  duties  of  the
Administrative  Agent,  and the term  "Administrative  Agent"  shall  mean  such
successor agent effective

509253-0191-02261-99A5F10H-CRA

<PAGE>


                                       40




upon such  appointment  and  approval,  and the  former  Administrative  Agent's
rights,  powers and duties as Administrative Agent shall be terminated,  without
any other or further act or deed on the part of such former Administrative Agent
or any of the  parties to this  Agreement  or any  holders  of the Loans.  If no
successor  agent has accepted  appointment as  Administrative  Agent by the date
that  is  30  days  following  a  retiring   Administrative  Agent's  notice  of
resignation,  the retiring Administrative Agent's resignation shall nevertheless
thereupon  become  effective and the Lenders shall assume and perform all of the
duties of the  Administrative  Agent  hereunder  until such time, if any, as the
Required  Lenders  appoint a successor  agent as provided  for above.  After any
retiring   Administrative  Agent's  resignation  as  Administrative  Agent,  the
provisions  of this Section 8 shall inure to its benefit as to any actions taken
or  omitted  to be  taken by it while it was  Administrative  Agent  under  this
Agreement and the other Loan Documents.

                                   SECTION 9.  MISCELLANEOUS

               9.1 Amendments  and Waivers.  Neither this  Agreement,  any other
Loan Document,  nor any terms hereof or thereof may be amended,  supplemented or
modified  except in  accordance  with the  provisions  of this  Section 9.1. The
Required  Lenders and the  Borrower  may,  or,  with the written  consent of the
Required Lenders,  the  Administrative  Agent and the Borrower may, from time to
time, (a) enter into written amendments, supplements or modifications hereto for
the purpose of adding any provisions to this Agreement or changing in any manner
the rights of the Lenders or of the  Borrower  hereunder  or (b) waive,  on such
terms and conditions as the Required Lenders or the Administrative Agent, as the
case may be, may specify in such  instrument,  any of the  requirements  of this
Agreement  or any  Default or Event of Default and its  consequences;  provided,
however,  that no such waiver and no such amendment,  supplement or modification
shall (i) eliminate or reduce any voting rights under this Section 9.1,  forgive
the principal amount or extend the final scheduled date of maturity of any Loan,
reduce the stated rate of any  interest or fee payable  hereunder  or extend the
scheduled  date of any payment  thereof,  or  increase  the amount or extend the
expiration date of any Lender's Commitment,  in each case without the consent of
each Lender directly affected thereby;  (ii) reduce any percentage  specified in
the definition of Required Lenders, consent to the assignment or transfer by the
Borrower of any of its rights and obligations under this Agreement and the other
Loan  Documents,  in each case without the consent of all Lenders;  (iii) amend,
modify  or  waive  any  provision  of  Section  8  without  the  consent  of the
Administrative  Agent.  Any such waiver and any such  amendment,  supplement  or
modification  shall  apply  equally to each of the  Lenders and shall be binding
upon the Borrower,  the Lenders, the Administrative Agent and all future holders
of the Loans.  In the case of any  waiver,  the  Borrower,  the  Lenders and the
Administrative  Agent  shall be  restored to their  former  position  and rights
hereunder  and under the  other  Loan  Documents,  and any  Default  or Event of
Default  waived  shall be  deemed to be cured  and not  continuing;  but no such
waiver shall extend to any  subsequent or other Default or Event of Default,  or
impair any right consequent thereon.

               9.2  Notices.  All  notices,  requests and demands to or upon the
respective  parties  hereto to be effective  shall be in writing  (including  by
telecopy),  and, unless otherwise expressly provided herein,  shall be deemed to
have been duly given or made when delivered,  or three Business Days after being
deposited in the mail, postage prepaid, or, in the case of telecopy notice, when
received,   addressed   as  follows  in  the  case  of  the   Borrower  and  the
Administrative  Agent,  and  as set  forth  in an  administrative  questionnaire

other address as may be hereafter notified by the respective parties hereto:

provided that any notice,  request or demand to or upon the Administrative Agent

               9.3 No Waiver; Cumulative Remedies. No failure to exercise and no
delay in exercising,  on the part of the Administrative Agent or any Lender, any
right,  remedy,  power or privilege  hereunder or under the other Loan Documents
shall operate as a waiver thereof;  nor shall any single or partial  exercise of
any right,  remedy,  power or privilege  hereunder preclude any other or further
exercise thereof or the exercise of any other right, remedy, power or privilege.
The rights,  remedies,  powers and privileges herein provided are cumulative and
not exclusive of any rights, remedies, powers and privileges provided by law.

               9.4   Survival   of   Representations    and   Warranties.    All
representations  and warranties made hereunder and in any document,  certificate
or statement  delivered pursuant hereto or in connection  herewith shall survive
the  execution  and delivery of this  Agreement  and the making of the Loans and
other extensions of credit hereunder.

               9.5 Payment of Expenses and Taxes. The Borrower agrees (a) to pay
or  reimburse  the  Administrative  Agent  for all its  out-of-pocket  costs and
expenses incurred in connection with the development,  preparation and execution
of, and any  amendment,  supplement or  modification  to, this Agreement and the
other Loan Documents and any other documents prepared in connection  herewith or
therewith,   and  the  consummation  and   administration  of  the  transactions
contemplated hereby and thereby, including the reasonable fees and disbursements
of  counsel  to the  Administrative  Agent and  filing  and  recording  fees and
expenses,  with  statements with respect to the foregoing to be submitted to the
Borrower  prior to the  Closing  Date (in the case of  amounts to be paid on the
Closing  Date) and from time to time  thereafter  on a  quarterly  basis or such
other periodic basis as the Administrative Agent shall deem appropriate,  (b) to
pay or reimburse each Lender and the Administrative  Agent for all its costs and
expenses  incurred in connection  with the  enforcement or  preservation  of any
rights  under  this  Agreement,  the other  Loan  Documents  and any such  other
documents, including the fees and

                                       42




disbursements of counsel  (including the allocated fees and expenses of in-house
counsel) to each Lender and of counsel to the Administrative  Agent, (c) to pay,
indemnify,  and hold each Lender and the Administrative Agent harmless from, any
and all recording and filing fees and any and all  liabilities  with respect to,
or resulting from any delay in paying,  stamp,  excise and other taxes,  if any,
that may be payable or determined to be payable in connection with the execution
and delivery of, or consummation or  administration  of any of the  transactions
contemplated by, or any amendment,  supplement or modification of, or any waiver
or consent under or in respect of, this Agreement,  the other Loan Documents and
any such other documents,  and (d) to pay,  indemnify,  and hold each Lender and
the Administrative  Agent and their respective officers,  directors,  employees,
affiliates, agents and controlling persons (each, an "Indemnitee") harmless from
and  against  any and  all  other  liabilities,  obligations,  losses,  damages,
penalties,  actions,  judgments,  suits, costs, expenses or disbursements of any
kind or nature whatsoever with respect to the execution, delivery,  enforcement,
performance and  administration of this Agreement,  the other Loan Documents and
any such other documents,  including any of the foregoing relating to the use of
proceeds  of the Loans or the  violation  of,  noncompliance  with or  liability
under, any Environmental Law applicable to the operations of the Borrower any of
its  Subsidiaries  or any of the Properties and the reasonable fees and expenses
of legal  counsel in  connection  with  claims,  actions or  proceedings  by any
Indemnitee  against the Borrower  under any Loan  Document (all the foregoing in
this clause (d), collectively,  the "Indemnified  Liabilities"),  provided, that
the Borrower shall have no obligation  hereunder to any Indemnitee  with respect
to Indemnified  Liabilities to the extent such Indemnified Liabilities are found
by a final and  nonappealable  decision of a court of competent  jurisdiction to
have  resulted  from  the  gross  negligence  or  willful   misconduct  of  such
Indemnitee.  Without  limiting  the  foregoing,  and to the extent  permitted by
applicable law, the Borrower agrees not to assert and to cause its  Subsidiaries
not to assert,  and hereby  waives  and agrees to cause its  Subsidiaries  to so
waive,  all rights for contribution or any other rights of recovery with respect
to all claims, demands,  penalties,  fines, liabilities,  settlements,  damages,
costs and expenses of whatever kind or nature, under or related to Environmental
Laws,  that  any of  them  might  have  by  statute  or  otherwise  against  any
Indemnitee.  All  amounts due under this  Section 9.5 shall be payable  promptly
after written demand therefor.  The agreements in this Section 9.5 shall survive
repayment of the Loans and all other amounts payable hereunder.

               9.6 Successors and Assigns;  Participations and Assignments.  (a)
This  Agreement  shall be binding upon and inure to the benefit of the Borrower,
the Lenders, the Administrative Agent, all future holders of the Loans and their
respective  successors  and assigns,  except that the Borrower may not assign or
transfer any of its rights or obligations under this Agreement without the prior
written consent of each Lender.

               (b) Any Lender  may,  without  the  consent of the  Borrower,  in
accordance with applicable law, at any time sell to one or more banks, financial
institutions or other entities (each, a "Participant")  participating  interests
in any Loan owing to such  Lender,  any  Commitment  of such Lender or any other
interest of such Lender  hereunder  and under the other Loan  Documents.  In the
event of any such sale by a Lender of a participating interest to a Participant,
such  Lender's  obligations  under this  Agreement to the other  parties to this
Agreement shall remain  unchanged,  such Lender shall remain solely  responsible
for the  performance  thereof,  such Lender  shall remain the holder of any such
Loan for all purposes under this Agreement and the other Loan Documents, and the
Borrower and the Administrative Agent shall continue to deal solely and directly
with such Lender in connection with such Lender's  rights and obligations  under
this Agreement and the other Loan  Documents.  In no event shall any Participant
under any such  participation  have any right to approve any amendment or waiver
of any

509253-0191-02261-99A5F10H-CRA

<PAGE>


                                       43




provision of any Loan Document,  or any consent to any departure by the Borrower
therefrom,  except to the extent that such  amendment,  waiver or consent  would
reduce  the  principal  of,  or  interest  on,  the  Loans or any  fees  payable
hereunder, or postpone the date of the final maturity of the Loans, in each case
to the extent subject to such participation. The Borrower agrees that if amounts
outstanding  under this Agreement and the Loans are due or unpaid, or shall have
been  declared or shall have become due and payable  upon the  occurrence  of an
Event of Default,  each  Participant  shall, to the maximum extent  permitted by
applicable  law,  be  deemed  to have the  right of  setoff  in  respect  of its
participating  interest in amounts owing under this Agreement to the same extent
as if the amount of its  participating  interest were owing  directly to it as a
Lender under this  Agreement,  provided that, in purchasing  such  participating
interest,  such  Participant  shall be deemed to have  agreed to share  with the
Lenders the  proceeds  thereof as  provided in Section  9.7(a) as fully as if it
were a Lender hereunder. The Borrower also agrees that each Participant shall be
entitled to the  benefits of Sections  2.13,  2.14 and 2.15 with  respect to its
participation in the Commitments and the Loans  outstanding from time to time as
if it was a Lender; provided that, in the case of Section 2.14, such Participant
shall have complied with the requirements of said Section and provided, further,
that no Participant  shall be entitled to receive any greater amount pursuant to
any such Section than the transferor  Lender would have been entitled to receive
in respect of the amount of the  participation  transferred  by such  transferor
Lender to such Participant had no such transfer occurred.

               (c) Any Lender (an "Assignor") may, in accordance with applicable
law, at any time and from time to time assign to any Lender,  any  affiliate  of
any Lender or any  Approved  Fund or, with the consent of the  Borrower  and the
Administrative Agent (which, in each case, shall not be unreasonably withheld or
delayed),  to an  additional  bank,  financial  institution  or other entity (an
"Assignee") all or, except in the case of an outstanding  Competitive  Loan, any
part  of  its  rights  and  obligations  under  this  Agreement  pursuant  to an
Assignment  and  Acceptance,  executed by such  Assignee,  such Assignor and any
other Person whose consent is required pursuant to this paragraph, and delivered
to the  Administrative  Agent for its  acceptance and recording in the Register;
provided  that no such  assignment  to an Assignee  (other than any Lender,  any
affiliate of any Lender or any Approved Fund) shall be in an aggregate principal
amount of less than  $5,000,000  (other than in the case of an assignment of all
of a Lender's  interests under this  Agreement),  unless otherwise agreed by the
Borrower and the Administrative  Agent. For purposes of the proviso contained in
the  preceding  sentence,  the amount  described  therein shall be aggregated in
respect  of each  Lender  and its  related  Approved  Funds,  if any.  Upon such
execution, delivery, acceptance and recording, from and after the effective date
determined  pursuant  to  such  Assignment  and  Acceptance,  (x)  the  Assignee
thereunder  shall  be a  party  hereto  and,  to the  extent  provided  in  such
Assignment and Acceptance, have the rights and obligations of a Lender hereunder
with a  Commitment  and/or  Loans as set  forth  therein,  and (y) the  Assignor
thereunder  shall, to the extent provided in such Assignment and Acceptance,  be
released  from its  obligations  under this  Agreement  (and,  in the case of an
Assignment and Acceptance  covering all of an Assignor's  rights and obligations
under  this  Agreement,  such  Assignor  shall  cease  to  be a  party  hereto).
Notwithstanding  any  provision of this Section 9.6, the consent of the Borrower
shall not be required  for any  assignment  that occurs when an Event of Default
pursuant to Section 7(f) shall have occurred and be  continuing  with respect to
the Borrower.

               (d) The  Administrative  Agent shall,  on behalf of the Borrower,
maintain at its address referred to in Section 9.2 a copy of each Assignment and
Acceptance  delivered to it and a register (the  "Register") for the recordation
of the names  and  addresses  of the  Lenders  and the  Commitment  of,  and the
principal  amount of the Loans  owing to,  each  Lender  from time to time.  The
entries in the Register

509253-0191-02261-99A5F10H-CRA

<PAGE>


                                       44




shall be conclusive,  in the absence of manifest error,  and the Borrower,  each
other Loan Party,  the  Administrative  Agent and the  Lenders  shall treat each
Person  whose name is recorded in the Register as the owner of the Loans and any
Notes  evidencing the Loans recorded therein for all purposes of this Agreement.
Any  assignment  of any  Loan,  whether  or not  evidenced  by a Note,  shall be
effective only upon  appropriate  entries with respect thereto being made in the
Register (and each Note shall expressly so provide).  Any assignment or transfer
of all or part of a Loan evidenced by a Note shall be registered on the Register
only upon  surrender  for  registration  of  assignment  or transfer of the Note
evidencing such Loan,  accompanied by a duly executed Assignment and Acceptance,
and thereupon one or more new Notes shall be issued to the designated Assignee.

               (e) Upon its receipt of an Assignment and Acceptance  executed by
an  Assignor,  an Assignee  and any other  Person  whose  consent is required by
Section  9.6(c),  together  with  payment  to  the  Administrative  Agent  of  a
registration and processing fee of $3,500,  the  Administrative  Agent shall (i)
promptly  accept such  Assignment and Acceptance and (ii) record the information
contained  therein in the Register on the  effective  date  determined  pursuant
thereto.

               (f) For  avoidance  of  doubt,  the  parties  to  this  Agreement
acknowledge  that the provisions of this Section 9.6  concerning  assignments of
Loans and Notes relate only to absolute  assignments and that such provisions do
not prohibit  assignments  creating security interests,  including any pledge or
assignment  by a  Lender  of any  Loan or Note to any  Federal  Reserve  Bank in
accordance with applicable law.

               (g) The  Borrower,  upon  receipt  of  written  notice  from  the
relevant  Lender,  agrees  to  issue  Notes  to any  Lender  requiring  Notes to
facilitate transactions of the type described in paragraph (f) above.

               9.7  Adjustments;  Set-off.  (a) Except to the  extent  that this
Agreement  expressly  provides  for  payments to be  allocated  to a  particular
Lender, if any Lender (a "Benefitted Lender") shall, at any time after the Loans
and other amounts  payable  hereunder shall  immediately  become due and payable
pursuant to Section 7,  receive  any  payment of all or part of the  Obligations
owing to it (whether  voluntarily  or  involuntarily,  by  set-off,  pursuant to
events or proceedings of the nature  referred to in Section 7(f), or otherwise),
in a greater  proportion  than any such payment to any other Lender,  if any, in
respect of the Obligations  owing to such other Lender,  such Benefitted  Lender
shall purchase for cash from the other Lenders a participating  interest in such
portion  of the  Obligations  owing  to each  such  other  Lender,  as  shall be
necessary to cause such  Benefitted  Lender to share the excess payment  ratably
with each of the Lenders; provided,  however, that if all or any portion of such
excess  payment  is  thereafter  recovered  from such  Benefitted  Lender,  such
purchase shall be rescinded,  and the purchase price returned,  to the extent of
such recovery, but without interest.

               (b) In  addition  to  any  rights  and  remedies  of the  Lenders
provided by law,  each Lender shall have the right,  without prior notice to the
Borrower,  any such notice being expressly  waived by the Borrower to the extent
permitted by  applicable  law,  upon any amount  becoming due and payable by the
Borrower  hereunder  (whether  at  the  stated  maturity,   by  acceleration  or
otherwise), to set off and appropriate and apply against such amount any and all
deposits  (general or special,  time or demand,  provisional  or final),  in any
currency,  and any other credits,  indebtedness or claims,  in any currency,  in
each case  whether  direct or  indirect,  absolute  or  contingent,  matured  or
unmatured,  at any time  held or owing by such  Lender  or any  branch or agency
thereof to or for the credit or the account of the Borrower,

                                       45




as the case may be. Each Lender  agrees  promptly to notify the Borrower and the
Administrative  Agent after any such setoff and application made by such Lender,
provided  that the failure to give such notice  shall not affect the validity of
such setoff and application.

               9.8  Counterparts.  This Agreement may be executed by one or more
of the parties to this Agreement on any number of separate counterparts, and all
of said  counterparts  taken  together shall be deemed to constitute one and the
same  instrument.  Delivery of an executed  signature  page of this Agreement by
facsimile  transmission  shall be effective  as delivery of a manually  executed
counterpart  hereof.  A set of the  copies of this  Agreement  signed by all the
parties shall be lodged with the Borrower and the Administrative Agent.

               9.9  Severability.  Any  provision  of  this  Agreement  that  is
prohibited or unenforceable in any jurisdiction  shall, as to such jurisdiction,
be ineffective to the extent of such  prohibition  or  unenforceability  without
invalidating  the  remaining  provisions  hereof,  and any such  prohibition  or
unenforceability   in  any   jurisdiction   shall  not   invalidate   or  render
unenforceable such provision in any other jurisdiction.

               9.10  Integration.  This  Agreement and the other Loan  Documents
represent  the  agreement  of the  Borrower,  the  Administrative  Agent and the
Lenders with respect to the subject  matter  hereof,  and there are no promises,
undertakings,  representations or warranties by the Administrative  Agent or any
Lender  relative to subject matter hereof not expressly set forth or referred to
herein or in the other Loan Documents.

               9.11 GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS
OF THE PARTIES  UNDER THIS  AGREEMENT  SHALL BE GOVERNED BY, AND  CONSTRUED  AND
INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

     9.12 Submission To Jurisdiction;  Waivers.  The Borrower hereby irrevocably

        York,  the courts of the United States for the Southern  District of New
        York, and appellate courts from any thereof;

               (b) consents that any such action or proceeding may be brought in
        such courts and waives any objection  that it may now or hereafter  have
        to the venue of any such action or  proceeding in any such court or that
        such  action or  proceeding  was  brought in an  inconvenient  court and
        agrees not to plead or claim the same;

               (c)  agrees  that  service  of  process  in any  such  action  or
        proceeding  may be effected by mailing a copy thereof by  registered  or
        certified  mail (or any  substantially  similar  form of mail),  postage
        prepaid, to the Borrower, as the case may be at its address set forth in
        Section 9.2 or at such other address of which the  Administrative  Agent
        shall have been notified pursuant thereto;

                                       46




               (d) agrees that  nothing  herein shall affect the right to effect
        service of process in any other  manner  permitted by law or shall limit
        the right to sue in any other jurisdiction; and

               (e) waives,  to the maximum  extent not  prohibited  by law,  any
        right it may have to claim or recover in any legal action or  proceeding
        referred  to  in  this  Section  any  special,  exemplary,  punitive  or
        consequential damages.

               9.13  Acknowledgements.  The Borrower hereby acknowledges that:

Employee.

"Good Reason" shall mean any of the following:

without  Employee's  express  written  consent,  any action,  or failure to take
action,  by the  Company,  the Board or the  shareholders  of the Company by the
Company that results in a diminution  in the  Executive's  position,  authority,
titles,  duties or responsibilities,  other than an isolated,  insubstantial and
inadvertent action that is not taken in bad faith and is remedied by the Company
promptly after receipt of notice thereof from the Executive;  a material  breach
by the Company of any material  provision of this Agreement which, if capable of

thereof is given by Employee to the company; without Employee's written consent,
the relocation of the principal  executive  offices of the Company to a location

Executive to continue to accrue benefits under Senior Executive  Retirement Plan
(SERP)  during the  Severance  Period;  and (C) shall  continue  to provide  the
Executive  with the Life  Insurance  Coverage and benefits as if he had remained
employed by the Company  pursuant to this Agreement  during the Severance Period
and then  retired (at which time he will be treated as eligible  for all retiree
welfare benefits and other benefits,  provided to retired senior executives,  to
the  extent  such  benefits  can be  provided  pursuant  to the plan or  program
maintained by the Company for its executives.  In addition to the foregoing, any
restricted stock outstanding on the Date of Termination shall be fully vested as
of  the  Date  of  Termination  and  all  options  outstanding  on the  Date  of
Termination shall be fully vested and exercisable and shall remain in effect and
exercisable  through the end of their  respective  terms,  without regard to the
termination of the Executive's  Employment (but in the case of options that were
not vested  immediately  before the Date of  Termination,  not longer than three
years).  Severance  Period  used here  shall  mean the  period  from the Date of
Termination through the end of the Employment Period.

(2) If the  Executive's  employment is  terminated by reason of the  Executive's
death or Disability during the Employment  Period,  the Company shall pay to the
Executive  or,  in  the  case  of the  Executive's  death,  to  the  Executive's

Date of Termination  that has not yet been paid; (b) an amount  representing the
Annual Incentive  Compensation and cash Long-Term Incentive Compensation for the
period that  includes  the Date of  Termination,  computed by assuming  that the
amount of all such Incentive Compensation would be equal to the target amount of
such  Incentive  Compensation  as in  effect  immediately  before  the  Date  of
Termination,  and multiplying that amount by a fraction,  the numerator of which
is the number of days in such period  through the Date of  Termination,  and the
denominator  of which is the total  number of days in the  relevant  performance
period; (c) any compensation  previously  deferred by the Executive that has not
been paid ; and (d) any accrued but unpaid  vacation  pay, and the Company shall
have no further  obligations under this agreement except as specified in Section

If such  termination  is by  Employee  for Good  Reason  or by the  Company  for
Disability or Good Cause,  such notice shall set forth in reasonable  detail the
reason for such termination and the facts and circumstances claimed to provide a
basis therefor.  Any notice purporting to terminate Employee's  employment which
is not  in  compliance  with  the  requirements  of  this  definition  shall  be
ineffective.  The Date of  Termination  shall mean ("Date of  Termination")  the
termination  date specified in a Notice of  Termination  delivered in accordance
with this Agreement.



                                   ARTICLE IV




4.1         CONFIDENTIAL INFORMATION.
            ------------------------

 The Executive shall hold in a fiduciary capacity for the benefit of the Company
all  secret or  confidential  information,  knowledge  or data  relating  to the
Company or any of its affiliated  companies and their  respective  business that
the Executive obtains during the Executive's employment by the Company or any of
its affiliated  companies and that is not public knowledge.  The Executive shall
not  communicate,  divulge or disseminate  Confidential  Information at any time
during or after  the  Executive's  employment  with the  Company,  except in the
course of performing his duties  hereunder or with the prior written  consent of
the Company or as otherwise required by law or legal process.  In no event shall
any asserted  violation of the provisions of this Section 4.1 constitute a basis
for  deferring or  withholding  any amounts  otherwise  payable to the Executive
under this agreement.

4.2         SUCCESSORS.

This  Agreement  is personal to the  Executive  and,  without the prior  written
consent of the Company,  shall not be assignable by the Executive otherwise than
by will or the laws of descent and  distribution.  This Agreement shall inure to
the benefit of and be enforceable by the Executive's legal representatives.

This Agreement shall inure to the benefit of and be binding upon the Company and
its  successors  and  assigns,  provided  that the  Company  may not assign this
Agreement  except in connection  with the  assignment or  disposition  of all or
substantially  all of the assets or stock of the Company,  or by law as a result
of a merger or consolidation.  In the event of such assignment, a failure by the
successor to  specifically  assume in writing,  delivered to the Executive,  the
obligations and liabilities of the Company  hereunder shall be deemed a material
breach of this Agreement.

4.3         NON EXCLUSIVITY OF RIGHTS.

Nothing in this Agreement shall prevent or limit the  Executive's  continuing or
future  participation in any plan,  program,  policy or practice provided by the
Company or any of its affiliated  companies for which the Executive may qualify.
Vested  benefits and other amounts that the  Executive is otherwise  entitled to
receive under the Incentive Compensation, the SERP, the Life Insurance Coverage,
or any other plan, policy,  practice or program of, or any contract or agreement
with,  the Company or any of its  affiliated  companies  on or after the Date of
Termination  shall be  payable in  accordance  with the terms of each such plan,
policy, practice,  program, contract or agreement, as the case may be, except as
explicitly modified by this Agreement.

4.4.        CERTAIN ADDITIONAL PAYMENTS BY THE COMPANY.
- ----        ------------------------------------------

(a) Any thing in this Agreement to the contrary notwithstanding, in the event it
shall be determined  that any payment or  distribution by the Company to, or for
the  benefit  of, the  Executive  (whether  paid or payable  or  distributed  or
distributable  pursuant  to the  terms  of  this  Agreement  or  otherwise,  but
determined without regard to any additional payments required under this Section
4.4) (a "Payment") would be subject to the excise tax imposed by Section 4999 of
the Internal  Revenue Code of 1986 (the  "Code"),  as amended or any interest or
penalties  are incurred by the  Executive  with respect to such excise tax (such
excise tax,  together  with any such  interest and  penalties,  are  hereinafter
collectively  referred  to as the "Excise  Tax"),  then the  Executive  shall be
entitled to receive and additional  payment (a "Gross-Up  Payment") in an amount
such that after payment by the Executive of all taxes (including any interest or
penalties imposed with respect to such taxes),  including,  without  limitation,
any income taxes (and any interest and penalties  imposed with respect  thereto)
and Excise Tax imposed  upon the  Gross-Up  Payment,  the  Executive  retains an
amount  of the  Gross-Up  payment  equal  to the  Excise  Tax  imposed  upon the
Payments.

(b)  Subject  to the  provisions  of  paragraph  (c) of this  Section  4.4,  all
determinations required to be made under this Section 4.4, including whether and
when a Gross-Up  Payment is required and the amount of such Gross-Up Payment and
the assumptions to be utilized in arriving at such determination,  shall be made
by  a  certified  public  accounting  firm  designated  by  the  Executive  (the
"Accounting Firm"), which shall provide detailed supporting calculations both to
the Company  and the  Executive  with 15 business  days of the receipt of notice
from the  Executive  that there has been a Payment,  or such  earlier time as is
requested by the Company.  In the event that the  Accounting  Firm is serving as
accountant or auditor for the  individual,  entity or group effecting the change
of control, the Executive shall appoint another nationally recognized accounting
firm to make the determinations  required hereunder (which accounting firm shall
then be referred to as the Accounting Firm hereunder).  All fees and expenses of
the Accounting Firm shall be borne solely by the Company.  Any Gross-Up Payment,
as determined  pursuant to this Section 4.4, shall be paid by the Company to the
Executive  within  five  (5)  days  of  the  receipt  of the  Accounting  Firm's
determination.  Any  determination  by the Accounting Firm shall be binding upon
the Company and the Executive. As a result of the uncertainty in the application
of  Section  4999 of the Code at the time of the  initial  determination  by the
Accounting Firm hereunder,  it is possible that Gross-Up Payments which will not
have been made by the Company should have been made ("Underpayment"), consistent
with the  calculations  required  to be made  hereunder.  In the event  that the
Company exhausts its remedies  pursuant to paragraph (c) of this Section 4.4 and
the  Executive  thereafter  is required to make a payment of any Excise Tax, the
Accounting Firm shall determine the amount of the Underpayment that has occurred
and any such  Underpayment  shall be promptly  paid by the Company to or for the
benefit of the Executive.

(c) The  Executive  shall  notify  the  Company  in  writing of any claim by the
Internal  Revenue Service that, if successful,  would require the payment by the
Company of the Gross-Up  Payment.  Such  notification  shall be given as soon as
practicable  but not later than ten (10)  business  days after the  Executive is
informed in writing of such claim and shall apprise the Company of the nature of
such  claim  and the  date on which  such  claim is  requested  to be paid.  The
Executive  shall not pay such claim prior to the  expiration  of the thirty (30)
day period  following  the date on which it gives such notice to the Company (or
such shorter period ending on the date that any payment of taxes with respect to
such claim is due). If the Company notices the Executive in writing prior to the
expiration  of such period that is desires to contest such claim,  the Executive
shall:

     (I) give the Company any  information  reasonably  requested by the Company
relating to such claim,

     (ii) take such  action in  connection  with  contesting  such  claim as the
Company  shall  reasonably  request  in  writing  from time to time,  including,
without limitation, accepting legal representation with respect to such claim by
an attorney reasonably selected by the Company,

     (iii)  cooperate  with the  Company in good faith in order  effectively  to
contest such claim, and,

     (iv) permit the Company to participate in any proceedings  relating to such
claim; PROVIDED, however, that the Company shall bear and pay directly all costs
and  expenses   (including   additional  interest  and  penalties)  incurred  in
connection  with  such  contest  and  shall  indemnify  and hold  the  Executive
harmless,  on an after-tax  basis,  for any Excise Tax or income tax  (including
inters  and  penalties  with  respect  thereto)  imposed  as a  result  of  such
representation  and payment of costs and  expenses.  Without  limitation  on the
foregoing  provisions  of this  paragraph  (c) of Section 4.4, the Company shall
control all  proceedings  taken in connection with such contest and, at its sole
option,  may pursue or forego any and all administrative  appeals,  proceedings,
hearings and conferences  with the taxing authority in respect of such claim and
may, at its sole option,  either direct the Executive to pay the tax claimed and
sue for a refund  or  contest  the  claim  in any  permissible  manner,  and the
Executive  agrees to  prosecute  such  contest  to a  determination  before  any
administrative  tribunal,  in a court of initial jurisdiction and in one or more
appellate courts, as the Company shall determine; PROVIDED, however, that if the
Company directs the Executive  harmless,  on an after-tax basis, from any Excise
Tax or income tax) including interest or penalties with respect thereto) imposed
with respect to such advance or with respect to any imputed  income with respect
to such  advance;  and PROVIDED,  further,  that any extension of the stature of
limitations  relating to payment of taxes for the taxable year of the  Executive
with  respect  to which  such  contested  amount is claimed to be due is limited
solely to such  contested  amount.  Furthermore,  the  Company's  control of the
contest  shall be limited  to issues  with  respect to which a Gross-Up  Payment
would be payable  hereunder  and the  Executive  shall be  entitled to settle or
contest,  as the case may be, any other  issue  raised by the  Internal  Revenue
Service or any other taxing authority.

(d) If, after the receipt by the Executive of an amount  advanced by the Company
pursuant to paragraph (c) of this Section 4.4, the Executive becomes entitled to
receive any refund with respect to such claim,  the Executive  shall (subject to
the Company's  complying with the  requirements of paragraph (c) of this Section
4.4,  promptly pay to the Company the amount of such refund  (together  with any
interest paid or credited thereon after taxes applicable thereto). If, after the
receipt by the  Executive  of an amount  advanced  by the  Company  pursuant  to
paragraph  (c) of this Section 4.4, a  determination  is made that the Executive
shall not be entitled to any refund with respect such claim and the Company does
not notify the  Executive  in  writing of its intent to contest  such  denial of
refund prior to the  expiration of 30 days after such  determination,  then such
advance  shall be forgiven and shall not be required to be repaid and the amount
of such advance  shall  offset,  to the extent  thereof,  the amount of Gross-Up
Payment required to be paid.

4.5         ATTORNEYS' FEES.

The Company agrees to pay, as incurred,  to the fullest extent permitted by law,
all legal fees and expenses that the Executive may reasonably  incur as a result
of any contest  (regardless  of the  outcome) by the Company,  the  Executive or
others of the validity or  enforceability  of or liability  under,  or otherwise
involving, any provision of the Agreement, together with interest on any delayed
payment at the applicable federal rate provided for in Section  7872(f)(2)(A) of
the Code.


4.6.        GOVERNING LAW.

This Agreement shall be governed by, and construed in accordance  with, the laws
of the State of New York,  without  reference to principles of conflict of laws.
The captions of this Agreement are not part of the provisions  here of and shall
have no force or effect. This Agreement may not be amended or modified except by

                  THIS  FIRST  AMENDMENT  TO  SUBORDINATED  LOAN  AGREEMENT  AND
PROMISSORY NOTE (this "First  Amendment") dated effective as of October 27, 1999
is  entered  into  by  and  between  HOUSTON  EXPLORATION  COMPANY,  a  Delaware
corporation (the "Company"),  and KEYSPAN  CORPORATION  d/b/a KeySpan Energy (as
successor to MarketSpan Corporation d/b/a KeySpan Energy) (the "Lender").

                              PRELIMINARY STATEMENT

                  The  Lender  and the  Company  are  parties  to  that  certain
Subordinated  Loan  Agreement  dated  as of  November  30,  1998 (as same may be
further amended, restated and extended herein, the "Credit Agreement") under and
subject to the terms of which the Lender has committed to make Advances  through
January 1, 2000, not to exceed  $150,000,000.00 in aggregate amount outstanding,
and that certain Promissory Note dated November 30, 1998 executed by the Company
to the order of Lender (the "Note").

                  The  Company  and  the  Lender  desire  to  amend  the  Credit
Agreement for the sole purpose of extending the maturity date.

                  NOW THEREFORE, in consideration of the premises and the mutual
agreements,  representations  and warranties herein set forth and for other good
and valuable consideration, the Company and the Lender hereby agree as follows:

                  SECTION 1. Definitions. Unless otherwise defined in this First
Amendment,  each  capitalized  term used in this First Amendment has the meaning
assigned to such term in the Credit Agreement.

                  SECTION 2. Amendments to the Credit Agreement.  (a) The Credit
Agreement and the Note are hereby  amended such that all references to "Maturity
Date" or "Termination  Date," and all references to "January 1, 2000" within the
definitions  of  Maturity  Date and  Termination  Date,  whether  in the  Credit
Agreement,  the schedules  thereto or in the Note, shall mean and be a reference
to the date of March 31, 2000.

                  (b) Specifically,  the section of the Credit Agreement on page
one thereof entitled "Maturity Date" and the identical  provision under the same
title on page one of Schedule I to the Credit  agreement  are hereby  amended by
deleting same in their entirety and replacing same with the following:

Maturity Date: All outstanding principal,  unpaid accrued interest and fees will
be repaid at  Maturity,  March 31,  2000.  Any  principal  amount  that  remains
outstanding  subsequent to the Maturity Date will be converted  into equity (the
number of shares to be issued to the Lender  will be  determined  based upon the
average of the closing prices of Houston  Exploration's common stock, rounded to
three decimal places, as reported under "NYSE Composite  Transaction Reports" in
the Wall Street  Journal  during the 20  consecutive  trading  days ending three
trading days prior to March 31, 2000.  Because the market  value  represents  an
average of the  Company's  common  stock over twenty  consecutive  trading  days
ending three  trading days prior to Maturity,  the market price may be higher or
lower  than the price of the  common  stock on the  conversion  date.  The total
amount  converted to equity shall not exceed the Total  Commitment  Amount.  Any
unpaid  accrued  interest  or fees that  remain  outstanding  subsequent  to the
Maturity  Date will be paid in cash.  Notwithstanding  the  foregoing,  upon any
sale,  transfer or other  disposition of the stock or  substantially  all of the
assets of the Company  prior to March 31, 2000,  all  outstanding  principal and
unpaid  accrued  interest and fees will be paid in cash on the  consummation  of
such sale, transfer or other disposition.

                  (c) The Credit Agreement is hereby amended to reflect the fact
that, as  consideration  for the extension of the Maturity Date as evidenced by,
and as a condition to the  effectiveness  of, this First Amendment,  the Company
shall pay to the Lender an up-front fee of Twelve  Thousand  and No/100  Dollars
($12,000.00).

                  SECTION 3. Ratification. The agreements and obligations of the
Company  under  the  Credit  Agreement,  the  Note  and any and all  other  Loan
Documents,   are  hereby  brought  forward,   renewed  and  extended  until  the
indebtedness  evidenced  by the  Credit  Agreement  and the Note shall have been
fully paid and  discharged.  The Credit  Agreement  and the Note,  and all terms
thereof shall remain in full force and effect.  The Lender hereby  preserves all
of its rights  against the Company,  and the Company hereby agrees that all such
rights are ratified and brought forward for the benefit of the Lender.

                  SECTION 4.  Representations  True; No Default. The Company and
the  Lender  represent  and  warrant  that this  First  Amendment  has been duly
authorized,  executed  and  delivered  on behalf of the  Company and the Lender,
respectively, and the Credit Agreement, as amended hereby, constitutes the valid
and legally  binding  agreement  of the Company and the Lender,  enforceable  in
accordance with its terms,  except as  enforceability  thereof may be limited by
bankruptcy,  insolvency,  reorganization  or  moratorium  or other  similar  law
relating to  creditors'  rights and by general  equitable  principles  which may
limit  the  right to obtain  equitable  remedies  (regardless  of  whether  such
enforceability is considered in a proceeding, in equity or at law);

                  SECTION  5. No  Obligation.  This  First  Amendment  shall not
create a course of dealing among or between the parties  hereto,  and no further
obligation  of any kind in excess of those  expressly  set forth herein shall be
inferred from this First Amendment.

                  SECTION 6. Conditions of  Effectiveness.  This First Amendment
shall become  effective on the date upon which this First  Amendment  shall have
been duly executed and delivered by the Company and the Lender,  together with a
certificate  of the Company  certifying as to (i) the  incumbency of the officer
executing  this  First  Amendment,  (ii) the  truth of the  representations  and
warranties in the Credit Agreement,  and (iii) the absence of any defaults under
the Credit Agreement.

                  SECTION  7.   Reference  to  the   Agreement.   (a)  Upon  the
effectiveness of this First Amendment, each reference in the Credit Agreement to
"hereunder,"  "herein,"  "hereof"  or words of like  import  shall mean and be a
reference to the Agreement, as affected and amended hereby.

                  (b) Upon effectiveness of this First Amendment, each reference
in the Credit  Agreement shall mean and be a reference to the Credit  Agreement,
as affected and amended hereby.

                  SECTION 8. Miscellaneous Provisions.  (a) This First Amendment
may be signed in any number of  counterparts,  each of which  shall be deemed an
original,  but  all  of  which  together  shall  constitute  one  and  the  same
instrument.

     (b) The headings  herein shall be accorded no  significance in interpreting
this First Amendment.

                  SECTION  9.  Governing  Law.  This  First  Amendment  shall be
governed by and construed in  accordance  with the laws of the State of New York
and applicable federal law.

                  SECTION  10.  FINAL  AGREEMENT  OF  THE  PARTIES.  THIS  FIRST
AMENDMENT,  THE  CREDIT  AGREEMENT,  THE  NOTES  AND THE  OTHER  LOAN  DOCUMENTS
CONSTITUTE  A "LOAN  AGREEMENT"  AS  DEFINED IN  SECTION  26.02(a)  OF THE TEXAS
BUSINESS AND COMMERCE CODE AND REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES
AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR,  CONTEMPORANEOUS OR SUBSEQUENT
AGREEMENTS OF THE PARTIES.

                  THERE ARE NO ORAL AGREEMENTS BETWEEN THE PARTIES.

                  IN  WITNESS  WHEREOF,  the  parties  have  caused  this  First
Amendment  to be executed by their  respective  duly  authorized  officers to be
effective as of the date first written above.

                    FIRST AMENDMENT TO EXPLORATION AGREEMENT


         This First Amendment to Exploration Agreement ("Amendment") is made and
entered  into  this  the  third  day  of  November  1999,  between  THE  HOUSTON

Original  Working  Interests in the Leases are less than 20.725 million dollars,
the shortage shall be added to the following year and KE&P shall pay during such
following year one hundred percent (100%) of all Intangible  Costs  attributable
to  THEC's  Original  Working  Interests  in the  Leases  until  KE&P  has  paid
Intangible Costs for such year totaling 20.725 million dollars plus the shortage

sentence,  during  the  Secondary  Term,  KE&P  shall pay all  Intangible  Costs
attributable  to THEC's  Original  Working  Interest  in the  Leases  until such
shortage  from the Primary Term,  if any, is expended and  thereafter  shall pay
fifty one and seventy five one  hundredths  percent  (51.75%) of all  Intangible
Costs  attributable to THEC's Original  Working  Interest in the Leases and THEC

<PAGE>



Development  Costs,  Seismic  Costs,  Leasehold  Costs,  Abandonment  Costs  and
Operating Costs  attributable to THEC's Original Working Interest in the Leases;
provided  that,  KE&P shall have no  obligation  to pay any of such costs to the
extent such costs  relate to a Lease  reassigned  to THEC under  Section 6.5 and
such costs accrue after such reassignment.

                                                        VI.

         Section 5.4 of the  Agreement is amended so that the existing  language
becomes Section 5.4A and the following is inserted as 5.4B:

         5.4B Primary Term  Commitment.  Notwithstanding  the foregoing  Section
5.4A, for the period  commencing  January 1, 2000, this Section 5.4B shall apply
prospectively  in lieu of  Section  5.4A.  KE&P's  obligation  to pay the  costs
specified in Sections 5.1 to 5.3 incurred during any quarter of the Primary Term
is limited to KE&P's Quarterly Commitment subject to the following:

         (a) If THEC  determines that the allocation to KE&P of its share of the
Drilling Costs and  Intangible  Costs of the first  Exploratory  Well on a Lease
will result in KE&P's  Quarterly  Commitment  being exceeded,  THEC shall notify
KE&P in writing of such fact prior to commencing such Well.  Within fifteen (15)
days (or such lesser period specified in the notice if the proposed spud date of
such Well is less than  thirty  (30)  days from the date of such  notice)  after
receiving  such  notice,  KE&P shall  notify  THEC in writing  whether or not it
approves such Well.  If KE&P  approves  such Well,  KE&P's share of the Drilling
Costs and Intangible Costs of such Well shall be deemed "Excess



                                                         5


<PAGE>



Costs" and, to the extent the Excess Costs result in KE&P's Quarterly Commitment
being exceeded, such commitment shall be increased accordingly for such quarter.
If KE&P does not approve such Well or fails to notify THEC of its decision, KE&P
shall forfeit its interests in such Well and the Lease on which it is located.

         (b) Except as provided in Section  5.4(a),  if KE&P is not obligated to
pay a portion of its share of the costs  specified in Sections 5.1 to 5.3 during
any quarter of the Primary  Term,  because its share exceeds in whole or in part
KE&P's Quarterly Commitment, and THEC pays such costs, KE&P shall reimburse THEC
for such costs out of KE&P's Quarterly  Commitment for the following  quarter on
or before thirty days after the end of the quarter in which THEC paid such costs
or, if the  Primary  Term has ended,  THEC  shall  receive  KE&P's  share of Net
Proceeds from all Wells drilled under this Agreement until such time as THEC has
received a sum of money  (exclusive of all Burdens,  Marketing  Costs and Taxes)
out of such  share  equal to  KE&P's  share of costs  which  were  paid by THEC,
provided,  however,  that the  amount to be paid by KE&P as  contemplated  above
shall not exceed twenty percent (20%) of KE&P's Quarterly Commitment without its
written consent.

         (c)  KE&P's  Quarterly  Commitment  shall  first be  applied to G and A
Costs,  Seismic Costs,  Leasehold Costs and Operating Costs and the remainder to
the Intangible Costs, Drilling Costs, Development Costs and Abandonment Costs.

     (d) All Drilling Costs, Intangible Costs and Development Costs for purposes
of  applying  the  limitations  of KE&P's  Quarterly  Commitment  shall,  at the
election of



                                                         6

THEC, be deemed to have been incurred  entirely on the date THEC submits to KE&P
the information set forth in Section 7.3 relating to the applicable operation or
the date of the AFE relating to the  expenditure  of such costs,  rather than on
the dates such costs are actually incurred.

         (e) Such  portion  of KE&P's  Yearly  Commitment  for the year 1999 not
expended or committed  for  expenditure  by December 31, 1999 shall be available
for use during the Primary Term only for Development  Costs and Intangible Costs
related to Development  Operations on Leases on which the first Exploratory Well
was spudded during the 1999 Program Year.

         (f) Such  portion  of KE&P's  Quarterly  Commitment,  for any  calendar
quarter,  not  expended or  committed  for  expenditure  by the last day of such
quarter  shall be available for use in  subsequent  quarters  during the Primary
Term only for  Development  Costs and  Intangible  Costs related to  Development
Operations on Leases on which the first  Exploratory Well was spudded during the
quarter to which the unused portion of the quarterly  Commitment relates, or any
previous quarter, including the 1999 Program Year.

                                                       VII.

         Section  10.4 of the  Exploration  Agreement  is  amended  so that  the
existing  language  becomes  Section  10.4(a) and the  following  is inserted as
Section 10.4(b):

         10.4(b) Budgets. Notwithstanding the foregoing Section 10.4(a), for the
period   commencing   January  1,  2000,   this  Section   10.4(b)  shall  apply
prospectively  in lieu of Section  10.4(a).  THEC shall submit  quarterly to the
Management  Committee THEC's Program Budget and a quarterly budget setting forth
the anticipated financial


                                                         7

requirements of KE&P under this Agreement. Such budgets for the first quarter of
the year 2000 shall be  submitted  on or before  January 1, 2000 and the budgets
for the following  quarters  during the terms on or before the first day of such
quarters.

         Except as herein amended,  the parties do hereby ratify and confirm the
Exploration Agreement.
