ITEM 1  Business

The Company and its Subsidiaries

National  Fuel Gas Company (the  Company or  Registrant),  a registered  holding
company under the Public  Utility  Holding  Company Act of 1935, as amended (the
Holding Company Act), was organized under the laws of the State of New Jersey on
December 8, 1902.  The Company is engaged in the  business of owning and holding
securities  issued by its subsidiary  companies.  Except as otherwise  indicated
below, the Company owns all of the outstanding  securities of its  subsidiaries.
Reference to "the Company" in this report means the Registrant or the Registrant
and  its  subsidiaries  collectively,  as  appropriate  in  the  context  of the
disclosure.

         The  Company is a  diversified  energy  company  consisting  of the six
reportable business segments. This report includes two newly-reported segments -
Energy  Marketing and Timber - and no longer  includes the  previously  reported
"Other Nonregulated"  segment. As a result of these refinements in the Company's
reportable  segments,  where appropriate in this report the information for 1998
and 1997 has been restated from the prior year's  presentation to conform to the
1999 presentation.

1.  The  Utility  segment  operations  are  carried  out by  National  Fuel  Gas
Distribution  Corporation  (Distribution  Corporation),  a New York corporation.
Distribution   Corporation   sells   natural  gas  and   provides   natural  gas
transportation  services through a local distribution  system located in western
New York and northwestern  Pennsylvania  (principal metropolitan areas: Buffalo,
Niagara Falls and Jamestown, New York; Erie and Sharon, Pennsylvania).

2. The Pipeline and Storage segment  operations are carried out by National Fuel
Gas Supply Corporation (Supply Corporation),  a Pennsylvania corporation, and by
Seneca  Independence  Pipeline  Company  (SIP), a Delaware  corporation.  Supply
Corporation  provides interstate natural gas transportation and storage services
for  affiliated  and  nonaffiliated  companies  through  (i) an  integrated  gas
pipeline   system   extending  from   southwestern   Pennsylvania   to  the  New
York-Canadian  border at the Niagara River, and (ii) 29 underground  natural gas
storage  fields  owned  and  operated  by  Supply  Corporation  and  four  other
underground  natural gas storage  fields  operated  jointly with  various  major
interstate gas pipeline  companies.  SIP holds a one-third  general  partnership
interest in Independence  Pipeline  Company  (Independence),  a Delaware general
partnership.  Independence,  after  receipt  of  regulatory  approvals  and upon
securing  sufficient  customer  interest,  plans to  construct  and  operate the
Independence  Pipeline,  a  370-mile  interstate  pipeline  system  which  would
transport  about  900,000  dekatherms  per day  (Dth/day)  of  natural  gas from
Defiance, Ohio to Leidy, Pennsylvania.*

3. The Exploration and Production  segment  operations are carried out by Seneca
Resources Corporation (Seneca), a Pennsylvania corporation. Seneca is engaged in
the  exploration  for, and the  development and purchase of, natural gas and oil
reserves in the Gulf Coast  Region of Texas and  Louisiana,  and in  California,
Wyoming and in the Appalachian region of the United States.

4. The  International  segment  operations  are  carried  out by Horizon  Energy
Development, Inc. (Horizon), a New York corporation.  Horizon engages in foreign
energy projects through the investments of its indirect subsidiaries as the sole
or  substantial  owner  of  various  business  entities.  Horizon  is  the  sole
shareholder of Horizon Energy Holdings,  Inc., a New York  corporation  which in
turn, owns 100% of Horizon Energy Development B.V. (Horizon B.V.).  Horizon B.V.
is a Dutch company whose principal assets consist of a majority ownership in (i)
Severoeeske  teplarny,  a.s.  (SCT),  a company with district  heating and power
generation  operations located in the northern part of the Czech Republic;  (ii)
Prvni  severozapadni  teplarenska,  a.s.  (PSZT), a wholesale power and district
heating company that is located in the Czech Republic in close proximity to SCT;
and (iii) Teplarna  Kromeriz,  a.s. (TK), a  district  heating  company  located
in the southeast region of the Czech Republic.

5. The Energy  Marketing  segment  operations  are carried out by National  Fuel
Resources,  Inc.  (NFR),  a New York  corporation  engaged in the  marketing and
brokerage  of  natural  gas  and  electricity  and  the  performance  of  energy
management services for industrial, commercial, public authority and residential
end-users throughout the northeast United States.

6. The Timber  segment  operations  are carried out by Highland Land & Minerals,
Inc. (Highland), a Pennsylvania  corporation,  and by a division of Seneca known
as its Northeast Division. Highland owns four sawmill operations in northwestern
Pennsylvania  and  processes  timber   consisting   primarily  of  high  quality
hardwoods. The Northeast Division of Seneca markets timber from its New York and
Pennsylvania land holdings.

         Financial information about each of the Company's business segments can
be  found  in Item 7,  MD&A  and  also  in Item 8 at Note I -  Business  Segment
Information.  The discussion of the Company's  business segments as contained in
the  business  segment  discussion  on  pages 7 to 16 of the  paper  copy of the
Company's combined Annual Report to Shareholders/Form  10-K, is included in this
electronic filing as Exhibit 13 and is incorporated herein by reference.

         The Company's other  wholly-owned  subsidiaries are not included in any
of the six reportable business segments and consist of the following:

o             Upstate Energy Inc.  (Upstate)  (formerly  known as Niagara Energy
              Trading Inc.), a New York corporation engaged in wholesale natural
              gas marketing and other energy-related activities;

o             Niagara   Independence   Marketing   Company   (NIM),  a  Delaware
              corporation which owns a one-third general partnership interest in
              DirectLink Gas Marketing Company (DirectLink),  a Delaware general
              partnership.  DirectLink  was  formed  to engage  in  natural  gas
              marketing and related businesses,  in part by subscribing for firm
              transportation capacity on the Independence Pipeline;

o             Leidy Hub, Inc. (Leidy),  a New York corporation formed to provide
              various  natural  gas hub  services  to  customers  in the eastern
              United States through a 50% ownership of Ellisburg-Leidy Northeast
              Hub Company (a Pennsylvania general partnership);

o             Data-Track  Account  Services,  Inc.  (Data-Track),   a  New  York
              corporation which provides collection services principally for the
              Company's subsidiaries; and

o             NFR Power, Inc. (NFR Power), a New York corporation capitalized by
              the  Company  in  1999  which,   while  not  actively   generating
              electricity  at this time, is  designated as an "exempt  wholesale
              generator" under the Holding Company Act.

         No  single  customer,  or  group of  customers  under  common  control,
accounted for more than 10% of the Company's consolidated revenues in 1999.

         Any reference to a year in this report is to the Company's  fiscal year
ended September 30 of that year unless otherwise noted.

Rates and Regulation
The Company is subject to regulation by the Securities  and Exchange  Commission
(SEC)  under  the  broad  regulatory  provisions  of the  Holding  Company  Act,
including provisions relating to issuance of securities,  sales and acquisitions
of securities and utility assets,  intra-Company transactions and limitations on
diversification.  The SEC and some members of Congress have advocated, on either
a stand-alone  basis or in conjunction with  legislation  which would deregulate
the  electric  industry,  the repeal of the Holding  Company  Act.  The proposed
legislation  currently  under  consideration  would transfer  certain  oversight
responsibilities to the various state public utility regulatory  commissions and
the Federal Energy  Regulatory  Commission (FERC) and would expand the access of
these bodies to the books and records of companies in a holding  company system.
Such legislation could actually increase  regulation of the Company,  especially
at the state level. Previous SEC rule changes,  however, have reduced the number
of  applications  required to be filed under the Holding  Company Act,  exempted
some routine financings and expanded diversification opportunities.  The Company
is unable to predict at this time what the ultimate outcome of current or future
legislative and/or regulatory  initiatives will be and,  therefore,  what impact
such efforts might have on the Company.*

         The Utility  segment's rates,  services and other matters are regulated
by the State of New York  Public  Service  Commission  (NYPSC)  with  respect to
services  provided  within  New  York  and by the  Pennsylvania  Public  Utility
Commission  (PaPUC) with respect to services provided within  Pennsylvania.  For
additional discussion of the Utility segment's rates and regulation, see Item 7,
MD&A under the heading "Rate Matters" and Item 8 at Note B-Regulatory Matters.

         The Pipeline and Storage  segment's  rates,  services and other matters
are regulated by the FERC. SIP is not itself regulated by the FERC, but its sole
business is the ownership of an interest in Independence,  whose rates, services
and other matters will be regulated by the FERC.  For  additional  discussion of
the Pipeline and Storage segment's rates and regulation,  see Item 7, MD&A under
the heading "Rate Matters" and Item 8 at Note B-Regulatory Matters.

         The discussion  under Item 8 at Note  B-Regulatory  Matters  includes a
description of the regulatory assets and liabilities  reflected on the Company's
Consolidated Balance Sheets in accordance with applicable  accounting standards.
To the extent that the criteria set forth in such  accounting  standards are not
met by the  operations  of the  Utility  segment  or the  Pipeline  and  Storage
segment, as the case may be, the related regulatory assets and liabilities would
be eliminated from the Company's Consolidated Balance Sheets and such accounting
treatment would be discontinued.

         In the  International  segment,  rates  charged for the sale of thermal
energy and  electric  energy at the retail level are subject to  regulation  and
audit in the Czech Republic by the Czech Ministry of Finance.  The regulation of
electric energy rates at the retail level  indirectly  impacts the rates charged
by the  International  segment for its electric  energy  sales at the  wholesale
level.

         In addition,  the Company and its  subsidiaries are subject to the same
federal,  state and local  regulations  on various  subjects as other  companies
doing similar business in the same locations.

The Utility Segment
The Utility segment contributed  approximately 49.4% of the Company's net income
available for common stock in 1999.

         Additional  discussion of the Utility  segment  appears in the business
segment discussion contained in this combined Annual Report to Shareholders/Form
10-K,  below in this Item 1 under the headings  "Sources and Availability of Raw
Materials"  and  "Competition,"  in  Item  7,  MD&A  and  in  Item  8  at  Notes
B-Regulatory  Matters,  H-Commitments and  Contingencies and I-Business  Segment
Information.

The Pipeline and Storage Segment
The  Pipeline  and  Storage  segment  contributed  approximately  34.6%  of  the
Company's net income available for common stock in 1999.

         Supply  Corporation  currently has service agreements for substantially
all of its  firm  transportation  capacity,  which  totals  approximately  1,943
million  cubic feet (MMcf) per day.  The  Utility  segment  has  contracted  for
approximately  1,126  MMcf  per  day or 58% of  that  capacity  until  2003  and
continuing  year-to-year  thereafter.  An additional 25% of Supply Corporation's
firm  transportation  capacity is subject to firm contracts  with  nonaffiliated
customers until 2003 or later.

         Supply  Corporation  has available for sale to customers  approximately
62.8 billion cubic feet (Bcf) of firm storage capacity.  The Utility segment has
contracted  for 26.0 Bcf or 41% of that  capacity,  in service  agreements  with
remaining   initial  terms  of   approximately  4  to  7  years  and  continuing
year-to-year  thereafter:  23.3 Bcf - 4 years; 2.0 Bcf - 7 years and 0.7 Bcf - 5
years. Nonaffiliated customers have contracted for the remaining 36.8 Bcf or 59%
of  firm  storage  capacity;  12.1  Bcf or  19% of  total  storage  capacity  is
contracted by nonaffiliated  customers until 2003 or later.  Supply  Corporation
has been  successful in marketing and obtaining  executed  contracts for storage
service (at discounted rates) as it becomes available and expects to continue to
do so.*

         Independence  has  filed  with the  FERC  signed  precedent  agreements
providing for firm transportation service totaling about 629,000 Dth/day for ten
years, out of total proposed  transportation  capacity of about 900,000 Dth/day.
The customer for 500,000 Dth/day of that total is DirectLink,  which is owned by
the sponsors of the Independence Pipeline, including NIM.

         Additional  discussion of the Pipeline and Storage  segment  appears in
the business  segment  discussion  contained in this  combined  Annual Report to
Shareholders/Form  10-K,  below under the headings  "Sources and Availability of
Raw Materials" and "Competition,"  Item 7, MD&A and Item 8 at Notes B-Regulatory
Matters, H-Commitments and Contingencies and I-Business Segment Information.

The Exploration and Production Segment
The Exploration and Production  segment  contributed  approximately  6.2% of the
Company's net income available for common stock in 1999.

         Additional discussion of the Exploration and Production segment appears
in the business segment  discussion  contained in this combined Annual Report to
Shareholders/Form  10-K,  below under the headings  "Sources and Availability of
Raw Materials" and "Competition,"  Item 7, MD&A and Item 8 at Notes A-Summary of
Significant  Accounting Policies,  F-Financial  Instruments,  I-Business Segment
Information,  J-Stock  Acquisitions and M-Supplementary  Information for Oil and
Gas Producing Activities.

The International Segment
The International  segment  contributed  approximately 2.0% of the Company's net
income available for common stock in 1999.

         Additional  discussion  of the  International  segment  appears  in the
business  segment  discussion  contained  in  this  combined  Annual  Report  to
Shareholders/Form  10-K,  below under the headings  "Sources and Availability of
Raw Materials" and  "Competition,"  Item 7, MD&A and Item 8 at Notes F-Financial
Instruments, I-Business Segment Information and J-Stock Acquisitions.

The Energy Marketing Segment
The Energy Marketing segment contributed approximately 1.8% of the Company's net
income available for common stock in 1999.

         Additional  discussion of the Energy  Marketing  segment appears in the
business  segment  discussion  contained  in  this  combined  Annual  Report  to
Shareholders/Form  10-K,  below under the headings  "Sources and Availability of
Raw Materials" and  "Competition,"  Item 7, MD&A and Item 8 at Notes F-Financial
Instruments and I-Business Segment Information.

The Timber Segment
The Timber segment  contributed  approximately  4.1% of the Company's net income
available for common stock in 1999.

         Additional  discussion  of the Timber  segment  appears in the business
segment discussion contained in this combined Annual Report to Shareholders/Form
10-K,  below under the headings  "Sources and Availability of Raw Materials" and
"Competition," Item 7, MD&A and Item 8 at Note I-Business Segment Information.

Sources and Availability of Raw Materials
Natural gas is the principal raw material for the Utility segment.  In 1999, the
Utility segment purchased 112.4 Bcf of gas. Gas purchases from various producers
and marketers in the  southwestern  United States under  long-term (two years or
longer)  contracts  accounted  for 66% of these  purchases.  Purchases of gas in
Canada and the United States on the spot market  (contracts of less than a year)
accounted for 29% of the Utility  segment's  1999 gas  purchases.  Gas purchases
from  Southern  Company  Energy  Marketing  L.P. and Dynegy  Marketing and Trade
represented  17% and 13%,  respectively,  of total  1999  gas  purchases  by the
Utility segment. No other producer or marketer provided the Utility segment with
10% or more of its gas requirements in 1999.

         Supply  Corporation  transports  and stores gas owned by its customers,
whose gas originates in the southwestern  and Appalachian  regions of the United
States as well as in Canada.  SIP, through  Independence,  proposes to transport
natural gas produced in Canada and in the midwestern United States.

         The  Exploration  and Production  segment seeks to discover and produce
raw  materials  (natural gas, oil and  hydrocarbon  liquids) as described in the
business  segment  discussion  contained  in  this  combined  Annual  Report  to
Shareholders/Form  10-K,  Item 7,  MD&A and Item 8 at Notes  I-Business  Segment
Information  and  M -  Supplementary  Information  for  Oil  and  Gas  Producing
Activities.

         Coal is the  principal  raw  material  for the  International  segment,
constituting  45% of the cost of raw  materials  needed to operate  the  boilers
which  produce steam or hot water.  Natural gas,  fuel oil,  limestone and water
combined account for the remaining 55% of such materials.  Coal is purchased and
delivered directly from the Mostecka Uhelna Spoleenost,  a.s. mine for Horizon's
largest  coal-fired  plant  under a contract  where price and  quantity  are the
subject of negotiation each year.  Natural gas is imported by the Czech Republic
government from Russia and the North Sea and is transported through the Transgas
pipeline  system which is majority  owned by the Czech  Republic  government and
purchased  by the  International  segment  from two of the  eight  regional  gas
distribution  companies.  Fuel  oil  used  to fire  certain  of the  boilers  is
purchased from both domestic Czech Republic and foreign refineries.

         The Energy  Marketing  segment depends on an adequate supply of natural
gas and electricity.  In 1999, this segment purchased  approximately 34.5 Bcf of
natural gas and approximately 73,000 megawatt hours of electricity.

         With  respect to the Timber  segment,  Highland  requires  an  adequate
supply of timber to process. Highland, however, mainly processes timber which is
located on land owned by Seneca,  and therefore,  the source and availability of
this segment's primary raw material are generally known in advance.

Competition
Competition in the natural gas industry  exists among  providers of natural gas,
as well as between  natural  gas and other  sources of  energy.  The  continuing
deregulation of the natural gas industry should enhance the competitive position
of  natural  gas  relative  to other  energy  sources  by  removing  some of the
regulatory  impediments to adding customers and responding to market forces.* In
addition, the environmental  advantages of natural gas compared with other fuels
should increase the role of natural gas as an energy source.* Moreover,  natural
gas is  abundantly  available  in North  America,  which  makes it a  dependable
alternative to imported oil.

         The electric  industry is moving toward a more competitive  environment
as a result of the Federal Energy Policy Act of 1992 and initiatives  undertaken
by the FERC and  various  states.  It is unclear at this point what  impact this
restructuring will have on the Company.*

         The Company  competes on the basis of price,  service and  reliability,
product performance and other factors.

Competition:  The Utility Segment
The changes  precipitated  by the FERC's  restructuring  of the gas  industry in
Order No. 636 are redefining the roles of the gas utility industry and the state
regulatory  commissions.  State  restructuring  initiatives  are under way, with
regulators in both New York and  Pennsylvania  adopting  retail  competition for
natural  gas  supply  purchases.  However,  the  Utility  segment's  traditional
distribution function remains largely unchanged. For further discussion of state
restructuring  initiatives  refer  to Item  7,  MD&A  under  the  heading  "Rate
Matters."

         Competition for large-volume  customers  continues with local producers
or pipeline companies  attempting to sell or transport gas directly to end-users
located within the Utility  segment's service  territories  (i.e.,  bypass).  In
addition,  competition  continues  with fuel oil suppliers and may increase with
electric utilities making retail energy sales.*

         The  Utility  segment  is now  better  able  to  compete,  through  its
unbundled  flexible  services,   in  its  most  vulnerable  markets  (the  large
commercial and industrial markets). The Utility segment continues to (i) develop
or promote new sources  and uses of natural gas and/or new  services,  rates and
contracts and (ii) emphasize and provide high quality service to its customers.

Competition:  The Pipeline and Storage Segment
Supply  Corporation  competes  for market  growth in the natural gas market with
other pipeline companies  transporting gas in the northeastern United States and
with other companies providing gas storage services. Supply Corporation has some
unique  characteristics which enhance its competitive  position.  Its facilities
are located  adjacent to Canada and the  northeastern  United States and provide
part of the link between  gas-consuming regions of the eastern United States and
gas-producing  regions of Canada and the  southwestern,  southern and midwestern
regions of the United States. This location offers the opportunity for increased
transportation and storage services in the future.*

         SIP,  through  Independence,  is  competing  for  customers  with other
proposed  pipeline  projects which would bring natural gas from the Chicago area
to the growing Northeast and Mid-Atlantic  United States markets. In combination
with expansion  projects of  Transcontinental  Gas Pipe Line Corporation and ANR
Pipeline Company,  Independence  intends to provide the least-cost path for this
service and will access the storage and market hub at Leidy,  Pennsylvania.*  It
is likely that not all of the  proposed  pipelines  will go forward and that the
first  project  built  will have an  advantage  over other  proposed  projects.*
Independence is attempting to be the first of the proposed  projects approved by
the FERC and the first built.* If completed,  the  Independence  pipeline  would
likely create opportunities for increased transportation and storage services by
Supply Corporation.*

Competition:  The Exploration and Production Segment
The Exploration and Production segment competes with other gas and oil producers
and  marketers  with  respect to its sales of oil and gas. The  Exploration  and
Production  segment also competes,  by competitive  bidding and otherwise,  with
other oil and natural gas exploration and production  companies of various sizes
for leases and drilling rights for exploration and development prospects.

         To compete in this environment,  Seneca originates and acts as operator
on   most   prospects,   minimizes   risk   of   exploratory   efforts   through
partnership-type   arrangements,   applies  the  latest   technology   for  both
exploratory  studies and drilling  operations  and focuses on market niches that
suit its size, operating expertise and financial criteria.

Competition:  The International Segment
Horizon  competes with other  entities  seeking to develop  foreign and domestic
energy projects.  Horizon,  through SCT and PSZT, faces competition in the sales
of thermal energy to large  industrial  customers.  Currently,  electric  energy
sales  are made to the  regional  electric  distribution  companies.  The  Czech
Ministry  of  Finance  has  announced  plans  to  privatize  these  distribution
companies.  While it is expected that these plans will increase  competition  at
the retail level of the electric energy market, it is unclear at this point what
impact this  privatization  will have on the wholesale  electric energy market.*
Both SCT and PSZT sell electricity at the wholesale level.

Competition:  The Energy Marketing Segment
The Energy  Marketing  segment  competes with other marketers of electricity and
natural gas and with other providers of energy management services. Although the
deregulation  of  electric  and  natural  gas  utilities  is  a  relatively  new
occurrence,  the competition in this area is well developed with regard to price
and services and derives primarily from both local and regional marketers.

Competition:  The Timber Segment
Highland  competes with other sawmill  operations and Seneca competes with other
suppliers  of timber.  This  competition  may be local,  regional,  national  or
international in scope.  These  competitors,  however,  are primarily limited to
those entities which either  process or supply high quality  hardwoods  species,
such as cherry,  oak and maple as veneer,  or saw logs or export logs ultimately
used in the production of high-end furniture, cabinetry and flooring. The Timber
segment markets its products both nationally and internationally.

Seasonality
Variations  in  weather  conditions  can  materially  affect  the  volume of gas
delivered  by the Utility  segment,  as  virtually  all of its  residential  and
commercial  customers  use gas for space  heating.  The  effect  on the  Utility
segment in New York is  mitigated  by a weather  normalization  clause  which is
designed  to adjust  the rates of retail  customers  to  reflect  the  impact of
deviations  from  normal  weather.  Weather  that is more than 2.2%  warmer than
normal results in a surcharge  being added to customers'  current  bills,  while
weather  that is more than 2.2%  colder than  normal  results in a refund  being
credited to customers'  current bills. In the  International  segment,  district
heating  operations in the Czech Republic are also subject to the seasonality of
weather.

         Volumes   transported  and  stored  by  Supply   Corporation  may  vary
materially  depending on weather,  without  materially  affecting  its earnings.
Supply  Corporation's  rates are based on a straight  fixed-variable rate design
which allows recovery of all fixed costs in fixed monthly  reservation  charges.
Variable  charges  based on volumes are designed  only to reimburse the variable
costs caused by actual transportation or storage of gas.

         Variations in weather  conditions can  materially  affect the volume of
gas and electricity consumed by customers of the Energy Marketing segment.

         The  activities of the Timber  segment vary on a seasonal basis and are
subject to weather  constraints.  The timber  harvesting and  processing  season
occurs when timber  growth is dormant and runs from  approximately  September to
March.  The  operations  conducted in the summer months focus on pulpwood and on
thinning out lower-grade  species from the timber stands to encourage the growth
of higher-grade species.

Capital Expenditures
A discussion of capital  expenditures by business segment is included in Item 7,
MD&A under the heading  "Investing Cash Flow" and subheading  "Expenditures  for
Long-Lived Assets."

Environmental Matters
A discussion of material environmental matters involving the Company is included
in  Item 7,  MD&A  under  the  heading  "Other  Matters"  and in  Item  8,  Note
H-Commitments and Contingencies.

Miscellaneous
The Company had a total of 3,807  full-time  employees  at  September  30, 1999,
2,401  employees  in all of its  U.S.  operations  and  1,406  employees  in its
International  segment. This represents a decrease of 3.47% from the 3,944 total
employed at September 30, 1998.

         Agreements  covering  employees in collective  bargaining  units in New
York were  renegotiated  in November  1997,  effective  December  1997,  and are
scheduled to expire in February  2001.  Agreements  covering  most  employees in
collective  bargaining units in Pennsylvania have been  renegotiated,  effective
November 1998, and are scheduled to expire in April and May 2003.

         The  Company  has  numerous  municipal  franchises  under which it uses
public  roads and  certain  other  rights-of-way  and  public  property  for the
location of facilities. When necessary, the Company renews such franchises.

ITEM 2  Properties

General Information on Facilities
The  investment  of the Company in net  property,  plant and  equipment was $2.4
billion at September 30, 1999.  Approximately  59% of this  investment is in the
Utility  and  Pipeline  and Storage  segments,  which are  primarily  located in
western New York and western Pennsylvania. The remaining investment in property,
plant and equipment is mainly in the Exploration  and Production  segment (29%),
which  is  primarily  located  in the  Gulf  Coast,  southwestern,  western  and
Appalachian  regions of the United States, the International  segment (9%) which
is located in the Czech  Republic,  and the Timber segment (3%) which is located
primarily in northwestern Pennsylvania.  During the past five years, the Company
has made  significant  additions  to property,  plant and  equipment in order to
expand and improve transmission and distribution  facilities for both retail and
transportation  customers,  to augment the reserve  base of oil and gas,  and to
purchase district heating and power generation facilities in the Czech Republic.
Net property,  plant and equipment has increased  $808.3 million,  or 52%, since
1994.

         The Utility  segment has the largest net investment in property,  plant
and  equipment,  compared with the Company's  other business  segments.  The net
investment  in  its  gas  distribution   network   (including  14,773  miles  of
distribution  pipeline) and its services  represent  approximately  58% and 29%,
respectively,  of the Utility  segment's  net  investment  of $919.6  million at
September 30, 1999.

         The Pipeline and Storage segment  represents a net investment of $466.5
million in property,  plant and  equipment at September  30, 1999.  Transmission
pipeline,  with a net cost of $145.3  million,  represents 31% of this segment's
total net investment and includes 2,583 miles of pipeline required to move large
volumes of gas throughout  its service area.  Storage  facilities  consist of 33
storage fields, 4 of which are jointly operated with certain pipeline suppliers,
and 482 miles of pipeline.  Net investment in storage facilities  includes $85.1
million of gas stored  underground-noncurrent,  representing the cost of the gas
required to maintain  pressure levels for normal  operating  purposes as well as
gas maintained for system  balancing and other  purposes,  including that needed
for no-notice  transportation  service.  The Pipeline and Storage segment has 29
compressor stations with 74,646 installed compressor horsepower.

         The  Exploration  and  Production  segment  had  a  net  investment  in
property, plant and equipment amounting to $674.8 million at September 30, 1999.

         The International  segment had a net investment in property,  plant and
equipment  amounting  to $203.5  million  at  September  30,  1999.  PSZT's  net
investment in district  heating and electric  generation  facilities  was $147.5
million;  SCT's net  investment  in  district  heating and  electric  generation
facilities  was $55.0  million;  and TK's net  investment  in  district  heating
facilities was approximately $1.0 million.

         The  Timber  segment  had a  net  investment  in  property,  plant  and
equipment  of  $88.9  million  at  September  30,  1999.  Located  primarily  in
northwestern   Pennsylvania,   the  net  investment   includes  4  sawmills  and
approximately 140,000 acres of timber.

         The Utility and Pipeline and Storage segments'  facilities provided the
capacity to meet its 1999 peak day sendout, including transportation service, of
1,909 MMcf,  which occurred on January 5, 1999.  Withdrawals from storage of 687
MMcf provided approximately 36% of the requirements on that day.

         Company  maps are  included  on pages 2 and 3 of the paper  copy of the
Company's combined Annual Report to Shareholders/Form  10-K, and are narratively

Exploration and Production Activities
The information  that follows is disclosed in accordance  with SEC  regulations,
and  relates  to the  Company's  oil and gas  producing  activities.  A  further
discussion  of oil and gas  producing  activities  is  included  in Item 8, Note
M-Supplementary  Information for Oil and Gas Producing  Activities.  Note M sets
forth proved developed and undeveloped reserve information for Seneca.  Seneca's
oil and gas reserves  reported in Note M as of September 30, 1999 were estimated
by Seneca's  qualified  geologists and engineers and were audited by independent
petroleum engineers from Ralph E. Davis Associates,  Inc. Seneca reports its oil
and gas  reserve  information  on an  annual  basis  to the  Energy  Information
Administration  (EIA).  The basis of reporting  Seneca's  reserves to the EIA is
identical to that reported in Note M.

         The  following  is a summary of certain oil and gas  information  taken
from Seneca's records:

South Lost Hills Waterflood Program
In  Seneca's  South Lost  Hills  Field  (acquired  in 1998 as part of the HarCor
Energy, Inc. and Bakersfield Energy Resources,  Inc.  acquisitions) a waterflood
project was initiated in 1996 on the Ellis lease in the Diatomite  reservior for
pressure maintenance and recovery enhancement  purposes.  Currently there are 27

ITEM   7  Management's  Discussion  and  Analysis of Financial  Condition  and
       Results of Operations

Results of Operations

1999 Compared with 1998
The Company's earnings were $115.0 million, or $2.98 per common share ($2.95 per
common share on a diluted  basis),  in 1999. This compares with 1998 earnings of
$23.2  million,  or $0.61 per common  share ($0.60 per common share on a diluted
basis).  Earnings  for  1998  included  a $79.1  million  (after  tax)  non-cash
impairment of the  Exploration  and Production  segment's oil and gas assets and
the non-cash  cumulative  effect of a change in accounting.  The 1998 accounting
change,  which  was a  change  in  depletion  methods  for the  Exploration  and
Production  segment's  oil and gas assets,  had a negative  $9.1 million  (after
tax), or $0.24 per common share, non-cash cumulative effect through fiscal 1997,
which was  recorded in the first  quarter of fiscal  1998.  Excluding  these two
non-cash  special items,  earnings for 1998 would have been $111.4  million,  or
$2.91 per common share ($2.88 per common share on a diluted basis).

         The  increase in 1999  earnings of $3.6 million  (exclusive  of the two
non-cash special items in 1998) is the result of higher earnings in the Utility,
Timber, Energy Marketing and International segments and in Corporate operations.
These higher earnings were offset in part by reduced earnings in the Exploration
and Production  segment.  The Pipeline and Storage  segment's  earnings remained
level with the prior  year.  Additional  discussion  of  earnings in each of the
business segments can be found in the business segment information that follows.

1998 Compared with 1997
The Company's earnings were $23.2 million,  or $0.61 per common share ($0.60 per
common  share on a diluted  basis),  in 1998.  These  earnings  include  the two
non-cash  special  items  discussed  above.  Without  these two non-cash  items,
earnings  for 1998 would have been  $111.4  million,  or $2.91 per common  share
($2.88 per common share on a diluted  basis).  This  compares  with  earnings of
$114.7  million,  or $3.01 per common share ($2.98 per common share on a diluted
basis), in 1997.

         The earnings decrease in 1998 was attributable to lower earnings of the
Company's  Utility,  Exploration and Production and Energy  Marketing  segments,
offset in part by higher earnings in the Pipeline and Storage segment and in the
International  and  Timber  segments  (both of which  incurred  a loss in 1997).
Additional  discussion of earnings in each of the business segments can be found
in the business segment information that follows.

Discussion  of  Asset Impairment and Cumulative Effect of a Change in Depletion
Method
Seneca  follows  the  full-cost  method  of  accounting  for  its  oil  and  gas
operations.  Under this method,  all costs  directly  associated  with  property
acquisitions,  exploration  and  development  are  capitalized,  up  to  certain
specified limits.  Due to significant  declines in oil prices in 1998,  Seneca's
capitalized costs under the full-cost method of accounting exceeded these limits
at March 31, 1998. Seneca was required to recognize an impairment of its oil and
gas  producing  properties  in the  quarter  ended March 31,  1998.  This charge
amounted  to $129.0  million  (pretax)  and reduced net income for 1998 by $79.1
million.

         Effective  October 1, 1997,  Seneca changed its method of depletion for
oil and gas properties  from the gross revenue method to the units of production
method. The units of production method was applied  retroactively to prior years
to determine the cumulative  effect  through  October 1, 1997.  This  cumulative
effect reduced earnings for 1998 by $9.1 million,  net of income tax.  Depletion
of oil and gas properties for 1999 and 1998 has been computed under the units of
production method.

1999 Compared with 1998
Operating  revenues  for the Utility  segment  decreased  $63.8  million in 1999
compared with 1998.  This resulted from a reduction in retail and off-system gas
sales revenue of $56.1 million and $15.3 million,  respectively, and a reduction
in other operating  revenue of $7.2 million.  These decreases were partly offset
by an increase in transportation revenue of $14.8 million.

           The recovery of lower gas costs (gas costs are  recovered  dollar for
dollar  in  revenues)  and the  general  base  rate  decrease  in the  New  York
jurisdiction  effective  October  1, 1998  caused  the  decrease  in retail  gas
revenue. The recovery of lower gas costs resulted from both lower retail volumes
sold of 3.2 billion  cubic feet (Bcf) and a lower  average cost of purchased gas
(see  discussion  of  purchased  gas below under the heading  "Purchased  Gas").
Despite  weather  that was  colder  than the prior  year,  retail  volumes  sold
decreased,  mainly due to the  migration  of  residential  and small  commercial
retail  customers  to  transportation  service.  This is the result of customers
turning to marketers for their gas supplies while using Distribution Corporation
for gas transportation service.  (Restructuring in the Utility segment's service
territory is further  discussed  in the "Rate  Matters"  section that  follows).
Transportation  revenue  increased and volumes are up 3.9 Bcf as a result of the
migration noted above and because of colder weather.  Off-system revenue is down
due to lower volumes sold of 3.7 Bcf.  Off-system sales are a function of demand
in the northeast markets.  Record storage levels at the beginning of the 1998-99
heating  season and a warmer than normal  winter in 1998-99  reduced  demand for
off-system sales. The margins resulting from off-system sales are minimal.

           The  decrease  in other  operating  revenue  of $7.2  million  is due
primarily to a $7.2 million gas  restructuring  reserve  reducing revenue in the
current year,  $6.0 million of revenue  recorded in 1998 as a result of Internal
Revenue  Service  (IRS)  audits and $0.5  million of a revenue  reduction in the
current year due to a final IRS audit settlement. These items are offset in part
by a $7.1 million lower refund  provision  recorded in 1999 as compared with the
1998 refund provision.  The gas  restructuring  reserve is to be applied against
incremental  costs  resulting  from the New  York  Public  Service  Commission's
(NYPSC) gas  restructuring  efforts (the NYPSC's gas  restructuring  efforts are
further  discussed  in the "Rate  Matters"  section that  follows).  The revenue
related to the IRS audits  represents  the rate recovery of interest  expense as
allowed by the New York rate settlement of 1996. The refund provision represents
the 50% sharing  with  customers  of  earnings  over a  predetermined  amount in
accordance  with the New York rate  settlements  of 1996 and 1998.  All of these
items are  included in the "Other"  category  of the Utility  Operating  Revenue
table above.

1998 Compared with 1997
Operating  revenues for the Utility  segment  decreased  $120.2  million in 1998
compared  with 1997.  This  resulted from a reduction in retail sales revenue of
$145.2 million offset in part by higher off-system sales revenue, transportation
revenue and other  revenue of $0.6  million,  $13.6  million and $10.8  million,
respectively.

           The  decrease  in retail gas  revenue  was caused by the  recovery of
lower gas costs offset in part by a general  base rate  increase in the New York
jurisdiction effective October 1, 1997. The recovery of lower gas costs resulted
from a decrease  in retail gas sales of 21.0 Bcf and a decrease  in the  average
cost of purchased  gas (see  discussion of purchased gas below under the heading
"Purchased  Gas").  While the decrease in gas sales also reflects,  in part, the
migration of residential and small commercial retail customers to transportation
service,  the major reason for the decrease  stems from warmer weather which was
on average 13.8% warmer in 1998 than in 1997 (see Degree Days table below).

           The  increase  in other  operating  revenue  of $10.8  million is due
primarily to $6.0 million of revenue recorded in 1998 as a result of IRS audits,
as discussed above, and $7.9 million of refund pool revenue, as discussed below,
offset in part by a $4.7 million  higher  refund  provision  recorded in 1998 as
compared  with 1997.  The  refund  provision  represents  the 50%  sharing  with
customers of earnings over a  predetermined  amount in  accordance  with the New
York rate settlement of 1996.

           As part of the 1996  rate  settlement  with the  NYPSC,  Distribution
Corporation  was  allowed to utilize  certain  refunds  from  upstream  pipeline
companies  and certain  credits  (referred  to as the  "refund  pool") to offset
certain  specific  expense items.  In September 1998,  Distribution  Corporation
recognized  $7.9  million  of the refund  pool as other  operating  revenue  and
recorded  an  equal  amount  of  Operation  and  Maintenance  (O&M)  expense  in
accordance with the settlement agreement.

Earnings

1999 Compared with 1998
In the Utility segment,  1999 earnings were $56.9 million,  up $5.1 million from
the prior year. This was largely because the settlement of the primary issues of
IRS audits of years  1977-1994  had a negative  impact on earnings  in 1998.  In
addition,  adjustments made relating to the final settlement of these audits had
a positive  impact to earnings in the current year.  Absent the IRS audit items,
earnings of the Utility segment were up $0.6 million from the prior year.

         Lower  O&M and  interest  expenses,  a lower  refund  provision  in the
current year (as noted in the revenue  discussion above),  positive  adjustments
for lost and  unaccounted-for  gas related to 1998 and 1999 and slightly  colder
weather (which mainly benefits the Pennsylvania jurisdiction), were the positive
contributors to earnings this year. These items offset the costs associated with
the current year's early retirement offers (which totaled $5.6 million,  pretax,
for this segment),  as well as the effects of a rate  settlement that included a
$7.2 million rate  reduction in New York that became  effective  October 1, 1998
and a special $7.2 million  (pretax)  reserve to be applied against  incremental
costs resulting from the NYPSC gas restructuring efforts, as discussed above.

         The  impact of  weather  on  Distribution  Corporation's  New York rate
jurisdiction is tempered by a weather normalization clause (WNC). The WNC in New
York,  which covers the  eight-month  period from October through May, has had a
stabilizing effect on earnings for the New York rate jurisdiction.  In addition,
in  periods  of  colder  than  normal  weather,  the WNC  benefits  Distribution
Corporation's  New  York  customers.  In  1999,  the WNC in New  York  preserved
earnings of  approximately  $0.6 million  (after tax) as weather,  overall,  was
warmer than normal for the period of October  1998  through May 1999.  Since the
Pennsylvania  rate  jurisdiction  does  not have a WNC,  uncontrollable  weather
variations  directly impact  earnings.  In the Pennsylvania  service  territory,
weather was 4.0% colder than 1998 and 9.9% warmer than normal.  The Pennsylvania
jurisdiction's  colder weather in 1999 compared with 1998 increased  earnings by
approximately $0.5 million (after tax).

1998 Compared with 1997
Utility  segment 1998 earnings were $51.8 million,  down $5.4 million from 1997.
This decrease was largely the result of the Utility segment  incurring  interest
expense in 1998, net of related rate recovery, in connection with the settlement
of the primary issues  relating to the previously  referred to settlement of the
IRS audits.  Absent this interest expense,  the Utility segment's  earnings were
down $1.6 million as compared to 1997. Warmer weather in 1998 compared with 1997
was the primary cause of the decrease.

         Partly offsetting the earnings  decrease caused by warmer weather,  the
Utility  segment   experienced  a  decrease  in  O&M  expense  as  a  result  of
management's  continued emphasis on controlling costs. Also contributing to this
decrease,  1997 O&M expense included $0.9 million of pretax expenses  associated
with an early retirement offer to certain Pennsylvania operating union employees
in 1997.

         In 1998, the WNC in New York preserved  earnings of approximately  $7.9
million (after tax) as weather,  overall,  was warmer than normal for the period
of October 1997 through May 1998. In the Pennsylvania service territory, weather
was 15.7%  warmer  than 1997 and 13.4%  warmer  than  normal.  The  Pennsylvania
jurisdiction's  warmer  weather in 1998 compared  with 1997 lowered  earnings by
approximately $4.0 million (after tax).

Purchased Gas
The cost of purchased gas is currently the Company's  single  largest  operating
expense.  Annual variations in purchased gas costs can be attributed directly to
changes in gas sales  volumes,  the price of gas  purchased and the operation of
purchased gas adjustment clauses.

         Currently,  Distribution  Corporation has contracted for long-term firm
transportation  capacity with Supply Corporation and six other upstream pipeline
companies,  for  long-term  gas supplies  with a  combination  of producers  and
marketers   and  for  storage   service  with  Supply   Corporation   and  three
nonaffiliated  companies.  In addition,  Distribution  Corporation can satisfy a
portion  of its gas  requirements  through  spot  market  purchases.  Changes in
wellhead prices have a direct impact on the cost of purchased gas.  Distribution
Corporation's   average  cost  of   purchased   gas,   including   the  cost  of
transportation  and storage,  was $3.82 per thousand cubic feet (Mcf) in 1999, a
decrease  of 7.5% from the  average  cost of $4.13 per Mcf in 1998.  The average
cost of purchased gas in 1998 was 3% lower than the $4.26 per Mcf in 1997.

1999 Compared with 1998
Operating  revenues  decreased  $2.2  million in 1999  compared  with 1998.  The
decrease  resulted  primarily  from  lower firm  transportation  revenue of $1.7
million, lower interruptible  transportation and storage service revenue of $1.0
million,  lower net  revenues  from  unbundled  pipeline  sales and open  access
transportation  of $0.8  million and an accrual for a gas  imbalance  payable of
$1.0  million.  These items were offset in part by higher firm  storage  service
revenue of $0.8 million and higher cashout revenue of $1.3 million.

         Approximately  $1.0 million of the decrease in the firm  transportation
revenue related to "pass through" type items (i.e., surcharges and refunds) that
correspondingly reduced O&M expense, thus having no bottom line earnings impact.
Interruptible   transportation   and  storage  service  revenue  decreased  (and
interruptible  volumes  transported  decreased  6.2  Bcf)  as a  result  of full
storages at the beginning of the 1998-99 heating season and a warmer than normal
winter in 1998-99;  thus Supply  Corporation  lacked available  storage space to
service interruptible  customers.  Lower interruptible storage service generally
results in lower  interruptible  transportation.  The higher cashout  revenue (a
cash  resolution of a gas imbalance  whereby a customer pays Supply  Corporation
for gas it receives  in excess of amounts  delivered  into Supply  Corporation's
system by the customer's  shipper) is offset by an equal amount of purchased gas
expense, thus there is no bottom line earnings impact.

         Transportation  volumes in this segment  decreased 4.7 Bcf.  Generally,
volume  fluctuations do not have a significant impact on revenues as a result of
Supply  Corporation's  straight  fixed-variable  (SFV) rate design.  However, as
mentioned  above,  lower  interruptible  transportation  volumes did  negatively
impact revenue for 1999.

1998 Compared with 1997
Operating  revenues  decreased  $1.7  million in 1998  compared  with 1997.  The
decrease  resulted  primarily  from lower net revenues from  unbundled  pipeline
sales and open access transportation of $1.8 million, lower firm storage service
revenues  of $1.3  million  and lower  cashout  revenue of $1.1  million.  These
decreases were partially offset by an increase in firm transportation revenue of
$1.3 million (resulting from demand charges related to the incremental expansion
of  this  segment's   Niagara  import   facilities)  and  higher   interruptible
transportation and storage service revenues of $0.7 million.

         Transportation  volumes in this  segment  increased  12.8 Bcf. As noted
above,  generally,  volume  fluctuations  do not have a  significant  impact  on
revenues  as a result of Supply  Corporation's  SFV rate  design.  However,  the
increase  in  capacity  stemming  from the  above  noted  incremental  expansion
contributed to higher demand charge revenue. Higher interruptible transportation
volumes also increased revenues.

Earnings

1999 Compared with 1998
Earnings in the Pipeline and Storage segment  remained at $39.8 million for 1999
and 1998. Lower revenues,  as discussed  above, and nonrecurring  income in 1998
from a buyout of a firm transportation  agreement by a customer in the amount of
$2.5 million  (pretax),  were offset by lower O&M and interest  expenses.  Items
causing   lower  O&M  expense  in  1999  when   compared  to  1998  include  the
establishment  of reserves,  in 1998, for preliminary  survey and  investigation
costs associated with a proposed incremental expansion project and a natural gas
gathering project (mainly due to lack of interest in furthering these projects).
In addition,  Supply Corporation  recognized a base gas loss at its Zoar Storage
Field in 1998.  In total,  these three items  amounted to $3.7 million of pretax
expense in 1998. In 1999, Supply  Corporation  reversed $0.8 million (pretax) of
the  gathering  project  reserve as it  recovered  that  amount  from its former
project partner. Also in 1999, Supply recovered, through insurance, $0.7 million
(pretax)  related  to the Zoar base gas loss.  Several  significant  items  also
increased O&M expense in 1999 when compared to 1998,  including early retirement
offers in 1999 (which  totaled $1.4 million,  pretax,  for this segment) and the
1998  reversal of a portion of a reserve set up in a prior  period for a storage
project.  Supply  Corporation  was able to recover  approximately  $1.0  million
(pretax)  by  selling  preliminary   engineering,   survey,   environmental  and
archeological information from this storage project to the Independence Pipeline
Company (the Independence Pipeline project is discussed further under "Investing
Cash Flow," subheading "Pipeline and Storage").

1998 Compared with 1997
In the  Pipeline  and  Storage  segment,  earnings  for  1998 of  $39.8  million
increased  $3.1 million when compared  with 1997.  This was mainly due to Supply
Corporation's   portion  of  interest  income  from  the  previously   mentioned
settlement  of IRS  audits.  Additional  income tax  expense  related to certain
unsettled issues was also recorded. Absent these IRS audit items, earnings would
have been down $0.3 million when compared with 1997. This decrease  reflects the
lower revenues, as discussed above, and an increase in O&M expense.  These items
were  offset  in  part  by  lower  interest  expense  and  a  buyout  of a  firm
transportation  agreement by a customer in the amount of $2.5 million  (pretax).
The higher O&M expenses resulted primarily from the above noted establishment of
reserves associated with a proposed incremental  expansion project and a natural
gas  gathering  project and the base gas loss at Zoar Storage  Field.  Partially
offsetting  these  increases  in O&M expense was the  reversal of a portion of a
reserve  set up in a prior  period for a storage  project and the fact that 1997
O&M expense  included $1.0 million of pretax  expenses  associated with an early
retirement offer.

1999 Compared with 1998
Operating  revenues  increased  $22.7 million in 1999  compared  with 1998.  Oil
production  revenues,  net of hedging  activities,  increased  $18.0  million as
production  increased 54% (mainly the result of West Coast  production  from the
properties acquired in 1998). Gas production revenue, net of hedging activities,
increased $0.3 million due to higher  production (also mainly the result of West
Coast  production  from the  properties  acquired in 1998).  Refer to the tables
below for production and price information. Revenue from Seneca's gas processing
plant,  acquired as part of the HarCor  Energy,  Inc.  (HarCor) and  Bakersfield
Energy  Resources (BER)  acquisitions in May and June 1998, was up $6.8 million.
These items were partly offset by a negative  mark-to-market  revenue adjustment
related  to written  options of $1.3  million.  Refer to further  discussion  of
written options in the "Market Risk Sensitive  Instruments" section that follows
and in Note F - Financial Instruments in Item 8 of this report.

1998 Compared with 1997
Operating  revenues  increased $5.0 million in 1998 compared with 1997. The main
reason for the  increase  was the $4.9  million in  revenues  related to the gas
processing  plant  acquired in 1998, as noted above.  While this gas  processing
plant  contributed a large amount of revenue,  this revenue was basically offset
by an equal amount of expense.

         Gas  production  revenues,  net of hedging  activities,  decreased $1.1
million as a result of decreased production, offset in part by higher gas prices
(after hedging). Refer to the tables below for production and price information.
The gas production  declines were mainly due to the shut-in of production during
the Gulf hurricane season and tropical  storms,  as well as the expected decline
in  production  of West  Cameron 552 and delays in  drilling  due to lack of rig
availability  in the first half of the year.  Oil  production  revenues,  net of
hedging  activities,  were basically even with 1997 as increased  production was
offset by lower oil prices (after  hedging).  The increase in oil production was
mainly the result of West Coast  production from the properties  acquired in the
Whittier Trust Company, HarCor and BER acquisitions.

(1)  1999 and 1998  includes low gravity oil which  generally  sells for a lower
     price.

         Seneca  utilizes price swap  agreements and options to manage a portion
of the market risk associated with  fluctuations in the price of natural gas and
crude oil. Refer to further  discussion of these hedging  activities below under
"Market Risk  Sensitive  Instruments"  and in Note F - Financial  Instruments in
Item 8 of this report.

Earnings

1999 Compared with 1998
In the  Exploration  and Production  segment,  1999 earnings of $7.1 million are
down $7.9 million  (exclusive  of the two non-cash  special  items in 1998) when
compared with 1998. This is largely because the settlement of the primary issues
of IRS audits of years  1977-1994 had a positive impact on earnings in the prior
year.  Absent the IRS audit items,  earnings of the  Exploration  and Production
segment were down $1.4 million from the prior year. Depressed oil and gas prices
for much of 1999 were the main reason for these lower  earnings.  Higher oil and
gas production  revenue,  as noted in the revenue  section above,  was offset by
increases in lease  operating,  depletion and interest expense related mainly to
Seneca's  acquisition activity in 1998. The increase in the gas processing plant
revenue of $6.8 million was largely offset by an increase in related expenses of
$6.2 million.

1998 Compared with 1997
Earnings in the  Exploration  and Production  segment were $15.0 million in 1998
(exclusive of the two non-cash special items), down $5.4 million from 1997. This
segment's  1998  earnings  include  interest  income  related to the  previously
mentioned settlement of IRS audits.  Without the positive contribution from this
interest  income,  earnings would be down $12.1 million when compared with 1997.
This decrease was mainly  because of low oil prices,  decreased  gas  production
(for reasons  discussed in the revenue section above) and higher lease operating
and interest  costs related to Seneca's  acquisition  activities in 1998.  These
circumstances  more than  offset the  positive  contribution  to  earnings  that
resulted from higher oil production and higher gas prices (after hedging).

(1) Gigajoules = one billion joules. A joule is a unit of energy.

1999 Compared with 1998
Operating  revenues  increased  $30.8 million in 1999  compared  with 1998.  The
increase in revenues as well as the  increase in heat and electric  volumes,  as
shown in the  tables  above,  reflects  the fact that 1999 was the first year in
which a full twelve  months of sales and revenues  are included for PSZT.  Sales
and revenues for 1998 include only eight months of activity as PSZT was acquired
in February 1998.

1998 Compared with 1997
Operating  revenues  increased  $74.3 million in 1998  compared  with 1997.  The
increase  primarily  reflects  100% of the  revenues  of SCT and PSZT for  1998.
Horizon  acquired  a 34%  equity  interest  in SCT in April  1997,  subsequently
increasing  that interest to 36.8% by September 30, 1997 (and thus accounted for
its  investment  in SCT under the equity method in 1997).  During 1998,  Horizon
increased  its  ownership in SCT to 82.7% as of September  30, 1998. In February
1998,  Horizon  acquired  a  75.3%  equity  interest  in PSZT  and  subsequently
increased  its  ownership  interest  to  86.2% as of  September  30,  1998.  The
consolidation  method was used to account  for the  investments  in SCT and PSZT
during 1998.

Earnings

1999 Compared with 1998
The  International  segment's  1999 earnings were $2.3 million,  or $1.0 million
higher than 1998  earnings.  The current year's  earnings  reflect a full twelve
months of results from PSZT,  while the prior year only included eight months of
earnings.  The contribution  from these additional  months in 1999 was offset in
part by higher interest expense during 1999. In addition, 1998 earnings included
a $5.1 million pretax net gain  associated with U.S.  dollar  denominated  debt,
which did not recur in the  current  year.  This debt was  converted  to a Czech
koruna denominated loan in December 1998.

1998 Compared with 1997
The  International  segment's  earnings  of $1.3  million  in 1998  were up $4.6
million when  compared to the loss  recognized  in 1997.  This segment  realized
increases  from  Horizon's  share of earnings from its two main  investments  in
district heating and power generation operations located in the Czech Republic.

         Because of the change in the nature of operations of the  International
segment over the past three years,  earnings  comparisons between 1999, 1998 and
1997 may not be meaningful. Future revenues from district heating operations are
expected to fluctuate with changes in weather.*

1999 Compared with 1998
Operating  revenues  increased  $11.9 million in 1999  compared with 1998.  This
increase reflects higher marketing volumes as NFR customers increased from 5,476
at September 30, 1998 to 17,480 at September 30, 1999.  Over 75% of the increase
in customers was residential.

1998 Compared with 1997
Operating  revenues  increased  $17.1 million in 1998  compared with 1997.  This
increase reflects higher marketing volumes as NFR customers increased from 1,307
at September 30, 1997 to 5,476 at September 30, 1998.

         NFR utilizes  exchange-traded  futures and  exchange-traded  options to
manage a portion of the market risk associated with fluctuations in the price of
natural gas. Refer to further discussion of these hedging activities below under
"Market Risk Sensitive Instruments" and in Note F-Financial  Instruments in Item
8 of this report.

Earnings

1999 Compared with 1998
The Energy Marketing  segment's 1999 earnings were $2.1 million,  an increase of
$1.3 million over 1998 earnings.  Volumes of natural gas marketed have increased
30% to 34.5 Bcf in 1999 from 26.5 Bcf in 1998 and margins were up from the prior
year.  These  positive  contributions  to earnings  were partly offset by higher
expenses for labor, office expense and advertising.

1998 Compared with 1997
The Energy  Marketing  segment's  earnings  for 1998 of $0.8  million  were $0.8
million below 1997  earnings.  Although  volumes of natural gas marketed were up
5.4 Bcf,  lower  earnings  reflect lower margins and higher O&M expense in 1998.
The increase in O&M expense  mainly  resulted from  expansion of NFR's  customer
base into new market areas.

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


1999 Compared with 1998
Operating revenues for the Timber segment increased $13.3 million. This increase
was  primarily  the result of higher  timber sales by Seneca of $3.6 million and
increased  log sales and kiln dry lumber sales of $4.9 million and $4.2 million,
respectively,  by Highland.  Revenue growth reflects the increased investment by
this segment in timber and sawmills.

1998 Compared with 1997
Operating  revenues for the Timber segment increased $6.3 million as a result of
higher  timber  sales by  Seneca  and  increased  lumber  sales  resulting  from
Highland's  purchase in 1998 of two new lumber  mills.  Highland also had a full
year of production from the mill it purchased in January 1997.

Earnings

1999 Compared with 1998
Timber  segment  earnings  of $4.8  million  in 1999 were up $2.9  million  when
compared  with 1998. As noted above,  timber  revenues  increased by 75%.  These
higher  revenues  were  partly  offset by higher  O&M,  depletion  and  interest
expenses.  Earnings growth reflects the increased  investment by this segment in
timber and sawmills.

1998 Compared with 1997
Timber  segment  earnings  of $1.9  million  in 1998 were up $2.5  million  when
compared to the loss recognized in 1997.  Higher revenues from the operations of
two new sawmills purchased in 1998 helped drive the earnings increase.

Other Income and Interest Charges
Although  variances in Other Income items and Interest  Charges are discussed in
the earnings discussion by segment above, following is a recap on a consolidated
basis:

Other Income
Other income  decreased  $23.5  million in 1999 and  increased  $32.7 million in
1998.  The 1999  decrease is  primarily  due to a decrease  in  interest  income
related to the  settlement  of IRS audits.  In 1999 and 1998,  $3.1  million and
$18.5 million,  respectively, of interest income was recognized related to these
audits.  Lower other income in 1999 also reflects two items  recorded in 1998: a
net gain of $5.1 million associated with U.S. dollar denominated debt carried on
the balance sheet of PSZT and a buyout of a firm  transportation  agreement by a
Pipeline  and Storage  segment  customer in the amount of $2.5  million.  Partly
offsetting  these items is a $2.4 million gain recorded in 1999  resulting  from
the  demutualization  of an insurance  company.  As a policyholder,  the Company
received stock of the insurance company as part of its initial public offering.

         The 1998  increase in other income is primarily  due to the above noted
$18.5 million of interest  income related to the  settlement of IRS audits,  the
$5.1 million net gain  associated with U.S.  dollar  denominated  debt, the $2.5
million  buyout of a firm  transportation  agreement  by a Pipeline  and Storage
segment  customer,  as well as $1.3 million of interest income on temporary cash
investments of SCT and PSZT.

Interest Charges
Interest on long-term debt increased  $12.2 million in 1999 and $11.0 million in
1998.  The increase in both years can be attributed  mainly to a higher  average
amount of  long-term  debt  outstanding.  Long-term  debt  balances  have  grown
significantly  over the past several years  primarily as a result of acquisition
activity in the Exploration and Production and International segments.

         Other  interest  charges  decreased  $9.8 million in 1999 and increased
$17.5  million in 1998.  The decrease in 1999  compared to 1998,  as well as the
increase in 1998 compared with 1997,  resulted  primarily from the $11.7 million
of interest expense recorded in 1998 related to the settlement of IRS audits. In
addition,  in 1999 and 1998,  interest on short-term debt increased  mainly as a
result of higher average amounts of debt outstanding.

Operating Cash Flow

Internally  generated  cash from  operating  activities  consists  of net income
available for common stock,  adjusted for noncash  expenses,  noncash income and
changes in operating assets and liabilities. Noncash items include depreciation,
depletion and amortization,  deferred income taxes, minority interest in foreign
subsidiaries,  the  cumulative  effect of a change in  accounting  for depletion
(1998) and the impairment of oil and gas producing properties (1998).

         Cash  provided by operating  activities in the Utility and Pipeline and
Storage segments may vary  substantially from year to year because of the impact
of  rate  cases.   In  the  Utility   segment,   supplier   refunds,   over-  or
under-recovered  purchased gas costs and weather also significantly  impact cash
flow.  The impact of weather on cash flow is tempered  in the Utility  segment's
New York rate jurisdiction by its WNC and in the Pipeline and Storage segment by
Supply Corporation's SFV rate design.

         Net cash provided by operating  activities  totaled  $271.9  million in
1999, an increase of $18.9 million  compared with the $253.0 million provided by
operating  activities  in 1998.  The  increase is  attributed  primarily  to the
Utility segment's  contribution  offset partly by a decrease in cash provided by
operations  in the  Exploration  and  Production  segment.  The  increase in the
Utility  segment is mainly the result of lower O&M  expenditures  combined  with
lower cash  disbursements  for taxes and interest.  While cash receipts from gas
sales and  transportation  service were down,  this  decrease was  substantially
offset by lower gas  purchase  expenditures.  The  decrease to cash  provided by
operations in the Exploration and Production  segment is primarily because of an
increase  in  interest  payments  stemming  from  higher  debt  related  to  the
acquisitions made in 1998.

Investing Cash Flow

Expenditures for Long-Lived Assets
Expenditures  for  long-lived  assets include  additions to property,  plant and
equipment  (capital   expenditures)  and  investments  in  corporations   (stock
acquisitions) or partnerships, net of any cash acquired.

         The Company's expenditures for long-lived assets totaled $269.9 million
in 1999. The table below presents these expenditures by business segment:

Utility
The majority of the Utility  capital  expenditures  were made for replacement of
mains and main extensions, as well as for the replacement of service lines.

Pipeline and Storage
The  majority of the  Pipeline and Storage  capital  expenditures  were made for
additions,  improvements  and  replacements to this segment's  transmission  and
storage systems.

         SIP made a $3.6 million  investment in 1999 in Independence  and had an
aggregate   investment   balance  of  $10.4   million  at  September  30,  1999.
Independence  is a Delaware  general  partnership  in which SIP owns a one-third
general  partnership  interest.   SIP's  cash  investments  were  financed  with
short-term  borrowings.  Independence  intends to build a 370 mile  natural  gas
pipeline (Independence Pipeline) from Defiance,  Ohio to Leidy,  Pennsylvania at
an  estimated  cost  of  $680  million.*  If the  Independence  Pipeline  is not
constructed, SIP's share of the development costs (including SIP's investment in
Independence Pipeline Company) is estimated not to exceed $13.0 million.*

Exploration and Production
Exploration and Production segment capital expenditures  included  approximately
$57.4 million on the offshore program in the Gulf of Mexico,  including offshore
drilling  expenditures,  offshore  construction and lease acquisition costs. The
remaining $40.2 million of capital  expenditures  included  onshore drilling and
construction costs for wells located in Louisiana,  Texas and California as well
as onshore geological and geophysical  costs,  including the purchase of certain
3-D seismic  data.  Of this  amount,  approximately  $20.4  million was spent on
development drilling, workover,  recompletion and facility construction costs on
the  leases  acquired  last  year  in the  Midway  Sunset,  Lost  Hills  area of
California.

International
The majority of the International segment capital expenditures were made by PSZT
for the  construction of new  fluidized-bed  boilers at its district heating and
power generation  plant to comply with stricter clean air standards.  Short-term
borrowings  and  cash  from  operations  were  used  to  finance  these  capital
expenditures.

         In fiscal 1999, Horizon, through a wholly-owned  subsidiary,  increased
its  ownership  interest  in SCT to  82.87%  for a  minimal  cost.  SCT in  turn
increased its  ownership  interest in  Jablonecka  teplarenska a realitni,  a.s.
(JTR),  a district  heating  plant in the northern  Bohemia  region of the Czech
Republic,  from 34% to 65.78%. The cost of acquiring these additional shares was
approximately $5.8 million ($5.7 million, net of cash acquired) and was financed
with short-term borrowings and cash from operations.

Energy Marketing
The capital  expenditures  consisted  primarily  of the  purchase of  furniture,
equipment and computer hardware and software for NFR's gas marketing operations.

Timber
The  majority of the Timber  segment's  capital  expenditures  consisted  of the
purchase  of  36,300  acres of land and  timber  from  PennzEnergy  Company  for
approximately  $47  million.   The  acquisition  was  financed  with  short-term
borrowings.  The remaining $9.7 million of capital  expenditures in this segment
were for other land, timber and equipment purchases.

Other Investing Activities
Other cash provided by or used in investing  activities  primarily reflects cash
received on the sale of various subsidiaries  investments in property, plant and
equipment, and cash used for investments in a mutual fund.

Estimated Capital Expenditures
The Company's estimated capital expenditures for the next three years are:*

         Estimated capital  expenditures for the Utility segment in 2000 will be
concentrated in the areas of main and service line improvements and replacements
and, to a minor extent, the installation of new services.*

         Estimated capital  expenditures for the Pipeline and Storage segment in
2000  will be  concentrated  in the  reconditioning  of  storage  wells  and the
replacement  of  storage  and   transmission   lines.   The  estimated   capital
expenditures  also  include  approximately  $9.4  million for the purchase of an
additional  interest  in both the Niagara  Spur Loop Line (a 49.2 mile,  30-inch
pipeline  extending  from Lewiston,  New York to East Aurora,  New York) and the
Ellisburg  Leidy  Line  (pipelines  and  facilities  extending  from  Ellisburg,
Pennsylvania to Leidy, Pennsylvania).*

         Estimated  capital   expenditures  in  2000  for  the  Exploration  and
Production segment includes approximately $78.3 million for the offshore program
in the Gulf of Mexico. Of this amount,  approximately  $53.3 million is intended
to be spent on exploratory and development drilling.  The estimated expenditures
also  includes  approximately  $33.9  million for the onshore  program.  Of this
amount,  approximately  $29.7 million is intended to be spent on exploratory and
development drilling.*

         Estimated capital  expenditures for the  International  segment will be
concentrated in the areas of improvements and  replacements  within the district
heating and power generation plants in the Czech Republic.*

         The Company continuously evaluates capital expenditures and investments
in corporations  and  partnerships.  The amounts are subject to modification for
opportunities  such as the  acquisition  of attractive  oil and gas  properties,
timber or storage  facilities and the expansion of transmission line capacities.
While  the  majority  of  capital   expenditures  in  the  Utility  segment  are
necessitated  by the continued need for  replacement  and upgrading of mains and
service lines, the magnitude of future capital expenditures or other investments
in the Company's other business segments depends, to a large degree, upon market
conditions.*

Financing Cash Flow

In order to meet the Company's capital requirements,  cash from external sources
must  periodically  be obtained  through  short-term  bank loans and  commercial
paper, as well as through issuances of long-term debt and equity securities. The
Company expects these traditional  sources of cash to continue to supplement its
internally generated cash during the next several years.*

         In February 1999, the Company issued $100.0 million of 6.0% medium-term
notes due in March 2009. After deducting underwriting discounts and commissions,
the net proceeds to the Company amounted to $98.7 million.  The proceeds of this
debt issuance,  together with other funds, were used to redeem $100.0 million of
5.58% medium-term notes which matured in March 1999.

         In July 1999, the Company  issued $100.0  million of 6.82%  medium-term
notes due to mature in August 2004. After deducting  underwriting  discounts and
commissions,  the net  proceeds to the Company  amounted to $99.5  million.  The
proceeds of this debt issuance,  together with other funds,  were used to redeem
$50.0  million  of 7.25%  medium-term  notes  which  matured in July 1999 and to
complete the redemption of HarCor's  14.875%  senior  secured  notes,  discussed
below.

         In March and July of 1999, the Company redeemed HarCor's 14.875% senior
secured notes.  The Company  redeemed the notes at a redemption price of 110% of
face value,  which  amounted to $59.1  million.  The senior  secured  notes were
recorded at fair market value on the opening balance sheet in 1998 to reflect an
effective  interest rate of 5.875% and the projected  redemption of this debt in
1999.

         The  Company's  embedded  cost of  long-term  debt was 7.0% and 6.9% at
September 30, 1999 and 1998, respectively.

         Consolidated  short-term  debt increased $67.2 million during 1999. The
Company  continues  to  consider  short-term  bank  loans and  commercial  paper
important  sources of cash for temporarily  financing  capital  expenditures and
investments  in  corporations  and/or  partnerships,  gas-in-storage  inventory,
unrecovered  purchased gas costs,  exploration and development  expenditures and
other working capital needs.  Fluctuations in these items can have a significant
impact on the amount and timing of short-term debt.

         In March 1998, the Company obtained  authorization  from the SEC, under
the  Holding  Company  Act,  to  issue  long-term  debt  securities  and  equity
securities   in  amounts  not   exceeding   $2.0  billion   during  the  order's
authorization  period,  which extends to December 31, 2002. In August 1999,  the
Company obtained  authorization from the SEC under the Securities Act of 1933 to
issue up to $625 million of debt and equity securities.

         The Company's present liquidity  position is believed to be adequate to
satisfy known demands.* Under the Company's  existing  indenture  covenants,  at
September  30,  1999,  the Company  would have been  permitted  to issue up to a
maximum of $485.0  million in additional  long-term  unsecured  indebtedness  at
projected market interest rates. In addition, at September 30, 1999, the Company
had regulatory authorizations and unused short-term credit lines that would have
permitted it to borrow an additional $356.5 million of short-term debt.

         The amounts and timing of the issuance  and sale of debt and/or  equity
securities will depend on market conditions, regulatory authorizations,  and the
requirements of the Company.

         The Company is involved in  litigation  arising in the normal course of
its  business.  In  addition to the  regulatory  matters  discussed  in Note B -
Regulatory  Matters,  in Item 8 of this report, the Company is involved in other
regulatory  matters  arising in the normal  course of business that involve rate
base,  cost of service and  purchased gas cost issues.  While the  resolution of
such  litigation or other  regulatory  matters  could have a material  effect on
earnings and cash flows in the year of resolution,  neither such  litigation nor
these other regulatory  matters are expected to materially  change the Company's
present  liquidity  position nor have a material adverse effect on the financial
condition of the Company at this time.*

Market Risk Sensitive Instruments

Energy Commodity Price Risk
Certain of the Company's subsidiaries (primarily Seneca and NFR) utilize various
derivative financial instruments (derivatives), including price swap agreements,
options,  exchange-traded  futures and  exchange-traded  options, as part of the
Company's  overall energy commodity price risk management  strategy.  Under this
strategy,  the  Company  manages a portion of the market  risk  associated  with
fluctuations in the price of natural gas and crude oil,  thereby  providing more
stability  to  operating  results.   The  derivatives   entered  into  by  these
subsidiaries  are  not  held  for  trading  purposes.  These  subsidiaries  have
operating procedures in place that are administered by experienced management to
monitor compliance with their risk management policies.

         The  following  tables  disclose  natural  gas and crude oil price swap
information by expected maturity dates for agreements in which Seneca receives a
fixed price in exchange for paying a variable  price as quoted in "Inside  FERC"
or on the New York Mercantile  Exchange.  Notional amounts (quantities) are used
to calculate the contractual  payments to be exchanged  under the contract.  The
tables do not reflect the earnings impact of the physical  transactions that are
expected to offset the  financial  gains and losses  arising from the use of the
price swap agreements. The weighted average variable prices represent the prices
as of September 30, 1999. At September 30, 1999, Seneca had not entered into any
natural gas or crude oil price swap agreements extending beyond 2002.

         At  September  30, 1999,  Seneca  would have had to pay the  respective
counterparties  to its  natural  gas  price  swap  agreements  an  aggregate  of
approximately  $2.4 million to terminate  the natural gas price swap  agreements
outstanding  at  that  date.  Seneca  would  have  had to pay  an  aggregate  of
approximately  $7.4  million to the  counterparties  to its crude oil price swap
agreements  to  terminate  the crude oil price swap  agreements  outstanding  at
September 30, 1999.

crude oil price  risk.  The tables do not  reflect  the  earnings  impact of the
physical  transactions that are expected to offset any financial gains or losses
that might arise if an option were to be exercised.

         At September 30, 1999, Seneca would have had to pay the counterparty to
its call  options $3.6  million on a net basis to  terminate  its call  options.
Seneca would have paid the counterparty  $8.2 million related to the exercise of
the written call and put options but would have received $4.6 million related to
Seneca's exercise of its purchased call option.

         The Company is exposed to credit risk on the price swap agreements that
Seneca  has  entered  into  as well  as on the  call  options  that  Seneca  has
purchased.  Credit risk relates to the risk of loss that the Company would incur
as a result of nonperformance  by counterparties  pursuant to the terms of their
contractual  obligations.  To mitigate such credit risk,  management  performs a
credit check and then on an ongoing basis monitors counterparty credit exposure.
The Company does not anticipate any material  impact to its financial  position,
results  of  operations,  or  cash  flows  as  a  result  of  nonperformance  by
counterparties.*

         At  September  30, 1999,  NFR would have  received  approximately  $2.3
million to settle the  exchange-traded  futures  outstanding  at that date.  NFR
would have paid approximately $1.2 million to settle its exchange-traded options
outstanding at September 30, 1999.

Exchange Rate Risk
Horizon's  investment in the Czech Republic is valued in Czech korunas,  and, as
such,  this  investment  is subject  to  currency  exchange  risk when the Czech
korunas  are  translated  into U.S.  dollars.  During  1999,  the  Czech  koruna
decreased in value in relation to the U.S.  dollar  resulting in a $11.7 million
negative adjustment to the Cumulative Foreign Currency Translation Adjustment (a
component of Accumulated Other Comprehensive Income).  Further valuation changes
to  the  Czech  koruna  would  result  in  corresponding  positive  or  negative
adjustments  to  the  Cumulative   Foreign  Currency   Translation   Adjustment.
Management  cannot predict whether the Czech koruna will increase or decrease in
value against the U.S. dollar.*

Interest Rate Risk
The Company's  exposure to interest rate risk  primarily  consists of short-term
debt instruments.  At September 30, 1999, these instruments  included short-term
bank loans and commercial  paper totaling  $392.3  million  (domestically).  The
interest rate on these short-term bank loans and commercial  paper  approximated
5.5%. These instruments also included $1.2 million of short-term bank loans held
by SCT in the Czech  Republic at September  30, 1999.  The interest  rate on the
Czech Republic loans approximated 6.4%.

         The following  table presents the principal cash repayments and related
weighted  average  interest  rates by expected  maturity  date for the Company's
long-term  fixed rate debt as well as the other debt of certain of the Company's
subsidiaries.  The interest  rates for the variable rate debt are based on those
in effect at September 30, 1999:

         PSZT  utilizes  an  interest  rate  swap  to  eliminate  interest  rate
fluctuations on its CZK 1,595,924,000  term loan ($47.7 million at September 30,
1999),  which  carries a variable  interest  rate of six month Prague  Interbank
Offered Rate  (PRIBOR)  plus 0.475%.  Under the terms of the interest rate swap,
which  extends  until  2001,  PSZT  pays a fixed  rate of 8.31% and  receives  a
floating  rate of six month  PRIBOR.  PSZT  would have paid  approximately  $1.0
million to settle the interest rate swap at September 30, 1999.

Rate Matters

Utility Operation

New York Jurisdiction

On October 21, 1998, the NYPSC approved a rate plan for Distribution Corporation
for the period beginning October 1, 1998 and ending September 30, 2000. The plan
was  the  result  of  a  settlement   agreement  entered  into  by  Distribution
Corporation,  Staff for the NYPSC (Staff), Multiple Intervenors (an advocate for
large industrial  customers) and the State Consumer  Protection Board. Under the
plan, Distribution Corporation's rates were reduced by $7.2 million, or 1.1%. In
addition,  customers are receiving up to $6.0 million in bill credits, disbursed
volumetrically  over the two year  term,  reflecting  a  predetermined  share of
excess  earnings  under a 1996  settlement.  An allowed return on equity of 12%,
above which additional  earnings will be shared equally with the customers,  was
maintained from a 1996 settlement.  Finally,  as provided by the rate plan, $7.2
million  of 1999  revenues  were set aside in a special  reserve  to be  applied
against Distribution  Corporation's incremental costs resulting from the NYPSC's
gas restructuring effort further described below.

         On November 3, 1998, the NYPSC issued its Policy  Statement  Concerning
                                                   ----------------------------
the Future of the Natural Gas  Industry in New York State and Order  Terminating
- -------------------------------------------------------------------------------
Capacity  Assignment  (Policy  Statement).  The Policy  Statement sets forth the
- --------------------
NYPSC's "vision" on "how best to ensure a competitive  market for natural gas in
New York." That vision includes the following goals:

         (1)   Effective  competition  in  the  gas  supply  market  for  retail
               customers;
         (2)   Downward pressure on customer gas prices;
         (3)   Increased customer choice of gas suppliers and service options;
         (4)   A provider of last resort (not necessarily the utility);
         (5)   Continuation  of reliable  service and  maintenance of operations
               procedures that treat all participants fairly;
         (6)   Sufficient  and  accurate  information  for  customers  to use in
               making informed decisions;
         (7)   The availability of information  that permits adequate  oversight
               of the market to ensure fair competition; and
         (8)   Coordination  of Federal and State policies  affecting gas supply
               and distribution in New York State.

         The Policy Statement  provides that the most effective way to establish
a competitive market in gas supply is "for local distribution companies to cease
selling gas." The NYPSC hopes to accomplish that objective over a three-to-seven
year transition  period,  taking into account  "statutory  requirements" and the
individual needs of each local distribution company (LDC).* The Policy Statement
directs Staff to schedule "discussions" with each LDC on an "individualized plan
that would effectuate our vision." In preparation for negotiations, LDCs will be
required to address issues such as a strategy to hold new capacity  contracts to
a minimum,  a long-term rate plan with a goal of reducing or freezing rates, and
a plan for  further  unbundling.  In  addition,  Staff  was  instructed  to hold
collaborative sessions with multiple parties to discuss generic issues including
reliability   and  market  power   regulation.   Distribution   Corporation  has
participated in the collaborative  sessions.  These collaborative  sessions have
not  yet  produced  a  consensus  document  on  all  issues  before  the  NYPSC.
Distribution   Corporation   will   continue  to   participate   in  all  future
collaborative sessions.

         Distribution  Corporation was recently  advised,  on an informal basis,
that its  "individualized  plan" for  restructuring to "effectuate [the NYPSC's]
vision"  may be included  in  discussions  anticipated  in  connection  with the
current rate settlement, which expires on its own terms on September 30, 2000.

         On June 7,  1999,  the NYPSC  issued a notice  requesting  comments  on
Staff's  proposal  for a "single  retailer"  billing  environment.  The proposal
recommends  that  electric  and gas  utilities  exit the billing  function at an
undetermined  future date. The retail  billing  function would then be performed
solely  by  unregulated  marketers.  Included  in  the  billing  proposal  is  a
recommendation  that utilities design a "back-out"  credit equal to the long run
costs  avoided by each  utility  when  billing  is  provided  by another  party.
Distribution  Corporation  filed  comments  opposing  much of the  proposal  but
supporting a suggested  interim  regime  where  multiple  billing  arrangements,
including utility billing, would be permitted.  This proceeding remains pending.
In  anticipation  of a NYPSC order partially  adopting  Staff's  recommendation,
Distribution  Corporation  is  exploring  the  development  of a retail  billing
service for sale to marketers serving  aggregated  customers.  There is a market
for retail billing services in Distribution Corporation's service territory, and
Distribution  Corporation believes that a service can be designed that will meet
the approval of the regulators.*

Pennsylvania Jurisdiction

Distribution  Corporation  currently  does not have a rate case on file with the
Pennsylvania  Public Utility  Commission  (PaPUC).  Management  will continue to
monitor its financial position in the Pennsylvania jurisdiction to determine the
necessity of filing a rate case in the future.

         Effective October 1, 1997,  Distribution  Corporation commenced a PaPUC
approved  customer  choice pilot program  called Energy  Select.  Energy Select,
which lasted until April 1, 1999, allowed  approximately 19,000 small commercial
and  residential  customers of  Distribution  Corporation in the greater Sharon,
Pennsylvania  area  to  purchase  gas  supplies  from  qualified,  participating
non-utility suppliers (or marketers) of gas. Distribution  Corporation was not a
supplier of gas in this pilot.  Under Energy  Select,  Distribution  Corporation
delivered the gas to the  customer's  home or business and remained  responsible
for reading customer  meters,  the safety and maintenance of its pipeline system
and responding to gas  emergencies.  NFR was a participating  supplier in Energy
Select.

         Effective  February 11, 1999,  Distribution  Corporation's  System Wide
Energy  Select  tariff was  approved by the PaPUC.  This  program is intended to
expand  the  Energy  Select  pilot  program  described  above  to  apply  across
Distribution  Corporation's  entire  Pennsylvania  service  territory.  The plan
borrows many features of the Energy Select pilot, but several  important changes
were  adopted.  Most  significantly,   the  new  program  includes  Distribution
Corporation as a choice for retail  consumers,  in  furtherance of  Distribution
Corporation's  objective  to remain a merchant.  Also  departing  from the pilot
scheme, Distribution Corporation resumes its role as provider of last resort and
maintains customer contact by providing a billing service on its own behalf and,
as an option, for participating marketers.

         A natural gas restructuring  bill was signed into law on June 22, 1999.
Entitled the Natural Gas Choice and Competition Act (Act),  the new law requires
all Pennsylvania  LDCs to file tariffs designed to provide retail customers with
direct access to competitive gas markets. Distribution Corporation submitted its
compliance  filing on October 1, 1999 for an effective  date on or about July 1,
2000. The filing largely mirrors the Energy Select program  currently in effect,
which substantially complies with the Act's requirements.  Currently the parties
to the  proceeding are engaged in routine  discovery and settlement  discussions
have  begun.  Distribution  Corporation  is unable to predict the outcome of the
proceeding at this time.

         Base  rate   adjustments   in  both  the  New  York  and   Pennsylvania
jurisdictions do not reflect the recovery of purchased gas costs. Such costs are
recovered  through  operation of the  purchased  gas  adjustment  clauses of the
appropriate regulatory authorities.

Pipeline and Storage

Supply Corporation  currently does not have a rate case on file with the Federal
Energy Regulatory  Commission (FERC). Its last case was settled with the FERC in
February 1996. As part of that settlement, Supply Corporation agreed not to seek
recovery  of  revenues  related  to  certain  terminated  service  from  storage
customers until April 1, 2000, as long as the terminations were not greater than
approximately  30%  of the  terminable  service.  Supply  Corporation  has  been
successful  in marketing and obtaining  executed  contracts for such  terminated
storage service (at discounted rates) and expects to continue obtaining executed
contracts for additional terminated storage service as it arises.*

Other Matters

Environmental Matters
It is the Company's  policy to accrue  estimated  environmental  clean-up  costs
(investigation  and  remediation)  when such amounts can reasonably be estimated
and it is  probable  that the  Company  will be  required  to incur such  costs.
Distribution  Corporation and Supply  Corporation  have estimated their clean-up
costs related to former  manufactured  gas plant and former gasoline plant sites
and third party  waste  disposal  sites will be in the range of $9.4  million to
$10.4  million.* The minimum  liability of $9.4 million has been recorded on the
Consolidated Balance Sheet at September 30, 1999. Other than discussed in Note H
(referred  to  below),  the  Company  is  currently  not  aware of any  material
additional exposure to environmental  liabilities.  However,  adverse changes in
environmental regulations or other factors could impact the Company.*

         The  Company is subject  to various  federal,  state and local laws and
regulations  relating  to the  protection  of the  environment.  The Company has
established  procedures for the ongoing evaluation of its operations to identify
potential  environmental  exposures  and comply  with  regulatory  policies  and
procedures.

         For further  discussion refer to Note H - Commitments and Contingencies
under the heading "Environmental Matters" in Item 8 of this report.

New Accounting Pronouncements
In June 1998, the Financial  Accounting  Standards Board (FASB) issued Statement
of  Financial   Accounting   Standards  No.  133,   "Accounting  for  Derivative
Instruments  and Hedging  Activities"  (SFAS 133). In June 1999, the FASB issued
SFAS 137,  "Accounting  for  Derivative  Instruments  and Hedging  Activities  -
Deferral of the  Effective  Date of SFAS 133." For a discussion  of SFAS 133 and
SFAS 137 and their impact on the Company,  see disclosure in Note A - Summary of
Significant Accounting Policies in Item 8 of this report.

Year 2000
Numerous  media  reports have  heightened  concern that  information  technology
computer  systems,  software programs and  semiconductors  may not be capable of
recognizing  dates after the Year 2000  because such systems use only two digits
to refer to a particular  year. Such systems may read dates in the Year 2000 and
thereafter  as if those  dates  represent  the year 1900 or  thereafter  and, in
certain instances, such systems may fail to function properly.

State of Readiness
The Company believes that all necessary work has been completed in order to make
its internal  computer  system Year 2000 ready.*  Following the completion of an
early-impact  analysis  study,  a formal  project  manager  at the  Company  was
designated  to  spearhead  the Year 2000  remediation  effort.  The  methodology
adopted  by the  Company  to address  the Year 2000  issue is a  combination  of
methods  recommended by respected  industry  consultants and efforts tailored to
meet the Company's  specific needs.  The Company's Year 2000 plan addresses five
primary areas.

A. Mainframe  Corporate  Business  Applications  Developed and Maintained by the
Company:  A detailed  plan and impact  analysis  was  conducted  in 1996-1997 to
determine the extent of Year 2000 implications on the Company's  mainframe-based
computer systems. The remediation and testing in this area have been completed.*

B. Personal Computer Business  Applications  Software Developed and Supported by
the Company:  Distribution  Corporation and Supply  Corporation  have retained a
consulting firm to perform a detailed  impact analysis of the personal  computer
business  application  systems supported by the Company's  Information  Services
Department.  Seneca has similarly  retained a consulting firm to review its Year
2000 issues.  These firms have either corrected Year 2000 problems identified by
their  analysis  or  advised  the  respective  subsidiaries  of the  potentially
problematic  computer  applications.  Certain  applications  identified  by  the
consulting firms as potentially  problematic have been retired and replaced with
Year 2000  compliant  applications.  The required  changes and testing for these
applications are complete.*

C.  Vendor-Supplied  Software,  Hardware,  and Services for  Corporate  Business
Applications  Supported by the Company:  This  category  includes all  mainframe
infrastructure  products as well as all PC client/server  software and hardware.
The  Company  has sent  letters  to its  vendors  asking if their  products  and
services  will  continue to perform as  expected  after  January 1, 2000.  These
vendors are responsible for approximately  200 products and services  associated
with corporate  computer  applications.  The Company has received responses from
all vendors  which the Company  believes  supply  critical  hardware,  software,
date-sensitive  embedded chips and related  computer  services.  The Company has
completed  testing and  implementation  of the  vendor-supplied  Year 2000 ready
products and services.*

D.  Vendor-Supplied  Products and Services Used on a Corporate Wide Basis:  This
category  includes the critical  products and services that are used by multiple
departments within the Company including all products  containing embedded chips
which  might be date  sensitive.  The  Company  has sent  letters to the primary
vendors who provide these products and services to the Company,  requesting Year
2000  compliance  plans.  The  Company is  monitoring  their  responses  and has
incorporated  them into the Company's  overall Year 2000 project and contingency
plans. The Company has completed testing and  implementation of the products and
services of these vendors (reference is made to the "Risks" section below).*

E. User-Department  Maintained Business  Applications:  The Company uses certain
business   software   applications   that  were   either   built   in-house   or
vendor-supplied  and  subsequently  maintained by individual  departments of the
Company.  The  scope  of such  applications  includes,  but is not  limited  to,
spreadsheets,  databases,  vendor  provided  products  and services and embedded
process  controls.  A  corporate  wide Year 2000 task  force is in place and has
established  a process to identify and resolve Year 2000  problems in this area.
This task force meets on a monthly basis to coordinate  ongoing  activities  and
report on the project status.  Providers of critical  products and services have
been  identified  and the Company has sent  letters  requesting  their Year 2000
compliance  plans.  Responses are being monitored and incorporated into the Year
2000 planning of the various  departments.  Based on responses  received to date
along with internal  testing,  the Company  believes that all  applications  and
services under this category are Year 2000 ready.*

Cost
The cost of upgrading both vendor supplied and internally  developed systems and
services is expensed as incurred and has amounted to approximately  $2.3 million
in total.  Minimal additional  expenses related to Year 2000  administration are
expected to be incurred.*

Risks
The  Company's  main concern is to ensure the safe,  reliable and  uninterrupted
production  and  delivery  of natural gas and  Company-provided  services to its
customers.  Based on the efforts discussed above, the Company expects to be able
to operate its own facilities without interruption and continue normal operation
in Year 2000 and beyond.*  However,  the Company has no control over the systems
and services  used by third parties with whom it  interfaces.  While the Company
has placed its major  third  parties on notice that the  Company  expects  their
products and services to perform as expected  after January 1, 2000, the Company
cannot predict with accuracy the actual adverse consequences to the Company that
could result if such third parties are not Year 2000  compliant.* The widespread
failure  of   electric,   telecommunication,   and  upstream  gas  supply  could
potentially affect gas service to utility customers, and the Company is pursuing
contingency plans to avoid such disruptions.*

         The  majority  of the devices  which  control  the  Company's  physical
delivery system are not believed to be susceptible to Year 2000 problems because
they do not contain  micro-processors.  The Company has  conducted  an extensive
review of its existing  micro-processors  (embedded technology) and has replaced
non-Year 2000 compliant hardware.

         Distribution  Corporation  is subject to regulatory  review by both the
NYPSC  and the  PaPUC.  Both of  these  regulatory  bodies  have  issued  orders
concerning the Year 2000 issue, and both have established dates in 1999 by which
jurisdictional  utilities must have taken the necessary steps to ensure that its
critical systems are Year 2000 ready. Distribution Corporation has, to date, met
the  requirements  of those orders and will  continue to comply with such orders
for the pertinent time periods specified in such orders.*

Contingency Planning
The Company formed its Corporate  Year 2000 task force in mid-1997.  The primary
function of this group was, and continues to be, to: (1) raise  awareness of the
Year  2000  issue  within  the  Company,   (2)  facilitate   identification  and
remediation  of  Year  2000  potential  problems  within  the  Company,  and (3)
facilitate and develop  corporate  contingency  plans. The group is comprised of
middle  to senior  level  managers  and  Company  executives.  The  Company  has
developed Year 2000 strategic  contingency  plans which have been prioritized in
relation   to  the   overall   corporation   in  the  order  of  human   safety,
reliability/delivery  of  Company  services  and  administrative  services.  The
Company has added the operational  specifics to these plans and is continuing to
hone them through  operational  drills.  During September through November 1999,
Distribution  Corporation and Supply  Corporation  conducted Year 2000 Readiness
Drills at critical Company owned operating facilities (e.g. compressor stations,
pipeline  interconnect  locations,  and  gas  dispatching  control  centers)  to
simulate  operation  under  the low  probability  occurrence  of  loss of  local
electricity or communications (primarily telephone).  These drills tested backup
generation equipment,  alternative communication functionality (radios), and our
employees'  preparedness  to manually  operate the physical gas delivery  system
should  these low  probability  events  occur.  These  drills  also  tested  and
sharpened  the  Company's  readiness  to  dispatch  and make  safe any  customer
emergencies,   which  might  occur  during  a  loss  of  electrical   supply  or
communications   functionality.   The  Company  will  have  a  very  significant
incremental workforce in the field during the critical Year 2000 rollover period
New Year's Eve. The  pertinent  portions of these plans have been filed with the
NYPSC whose review is ongoing.  Distribution  Corporation and Supply Corporation
are currently  working with other  utilities in their service areas and regional
Emergency Management Services to establish communication channels and procedures
in the low probability event of a serious Year 2000 disruption.  The Company has
always had  disaster/contingency  plans to deal with  operational  gas supply or
delivery problems,  loss of the corporate data center, and loss of the corporate
customer  telephone  centers.  These plans,  in  conjunction  with the Year 2000
drills, enable the Company to verify its readiness and ability to operate in the
event of  failures  resulting  from Year 2000  problems  arising  outside of the
Company (i.e., loss of electricity,  telephone service, etc.). All critical Year
2000 contingency plans have been completed.*

         All of the  above  Year  2000  information  is a  YEAR  2000  READINESS
DISCLOSURE made pursuant to the Year 2000  Information and Readiness  Disclosure
Act of 1998.

Effects of Inflation
Although the rate of inflation has been  relatively low over the past few years,
and thus has  benefited  both  the  Company  and its  customers,  the  Company's
operations remain sensitive to increases in the rate of inflation because of its
capital  spending  and the  regulated  nature of a  significant  portion  of its
business.

Safe Harbor for Forward-Looking Statements
The Company is including  the  following  cautionary  statement in this combined

Report of Management
- --------------------

Management is  responsible  for the  preparation  and integrity of the Company's
financial statements.  The financial statements have been prepared in accordance
with  generally  accepted  accounting  principles and  necessarily  include some
amounts that are based on management's best estimates and judgment.

         The   Company   maintains   a  system  of   internal   accounting   and
administrative   controls  and  an  ongoing  program  of  internal  audits  that
management believes provide reasonable assurance that assets are safeguarded and
that  transactions  are  properly  recorded  and  executed  in  accordance  with
management's  authorization.   The  Company's  financial  statements  have  been
examined by our independent accountants,  PricewaterhouseCoopers LLP, which also
conducts a review of  internal  controls  to the extent  required  by  generally
accepted auditing standards.

         The Audit  Committee  of the  Board of  Directors,  composed  solely of
outside    directors,    meets   with   management,    internal   auditors   and
PricewaterhouseCoopers  LLP to review  planned  audit  scope and  results and to
discuss  other  matters  affecting  internal  accounting  controls and financial
reporting. The independent accountants have direct access to the Audit Committee
and periodically meet with it without management representatives present.






Report of Independent Accountants
- ---------------------------------


To the Board of Directors
and Shareholders of
National Fuel Gas Company

In our opinion, the consolidated financial statements listed in the accompanying
index  present  fairly,  in all material  respects,  the  financial  position of
National Fuel Gas Company and its  subsidiaries  at September 30, 1999 and 1998,
and the results of their  operations  and their cash flows for each of the three
years in the period ended  September  30, 1999, in  conformity  with  accounting
principles generally accepted in the United States. In addition, in our opinion,
the  financial  statement  schedules  listed in the  accompanying  index present
fairly, in all material respects, the information set forth therein when read in
conjunction with the related consolidated financial statements.  These financial
statements  and  financial  statement  schedules are the  responsibility  of the
Company's  management;  our  responsibility  is to  express  an opinion on these
financial  statements and financial  statement schedules based on our audits. We
conducted our audits of these  statements in accordance with auditing  standards
generally accepted in the United States,  which require that we plan and perform
the audit to obtain reasonable  assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence  supporting the amounts and  disclosures  in the financial  statements,
assessing the  accounting  principles  used and  significant  estimates  made by
management,  and evaluating the overall  financial  statement  presentation.  We
believe  that our audits  provide a reasonable  basis for the opinion  expressed
above.

         As discussed in Note A to the consolidated  financial  statements,  the
Company changed its method of depletion for oil and gas properties in 1998.

         The preparation of the consolidated  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.

Reclassification
Certain prior year amounts have been  reclassified  to conform with current year
presentation.

Regulation
Two of the Company's principal subsidiaries, Distribution Corporation and Supply
Corporation, are subject to regulation by certain state and federal authorities.
Distribution  Corporation and Supply Corporation have accounting  policies which
conform to generally  accepted  accounting  principles,  as applied to regulated
enterprises,  and  are  in  accordance  with  the  accounting  requirements  and
ratemaking practices of the regulatory authorities.  Reference is made to Note B
- - Regulatory Matters for further discussion.

         In the  International  segment,  rates  charged for the sale of thermal
energy and  electric  energy at the retail level are subject to  regulation  and
audit in the Czech Republic by the Czech Ministry of Finance.  The regulation of
electric energy rates at the retail level  indirectly  impacts the rates charged
by the  International  segment for its electric  energy  sales at the  wholesale
level.

Revenues
Revenues are recorded as bills are  rendered,  except that service  supplied but
not  billed is  reported  as  "Unbilled  Utility  Revenue"  and is  included  in
operating revenues for the year in which service is furnished.

Unrecovered Purchased Gas Costs and Refunds
Distribution Corporation's rate schedules contain clauses that permit adjustment
of revenues to reflect  price changes from the cost of purchased gas included in
base  rates.  Differences  between  amounts  currently  recoverable  and  actual
adjustment  clause  revenues,  as well as other price  changes and  pipeline and
storage  company  refunds not yet  includable  in adjustment  clause rates,  are
deferred and accounted for as either unrecovered  purchased gas costs or amounts
payable to customers.

         Distribution  Corporation's rate settlements with the State of New York
Public Service  Commission  (NYPSC) include provisions for a sharing of earnings
over a specified  rate of return on equity.  Estimated  refund  liabilities  are
recorded over the term of the  settlements  which reflect  management's  current
estimate of such refunds.  Reference is made to Note B - Regulatory  Matters for
further discussion.

Property, Plant and Equipment
The principal assets, consisting primarily of gas plant in service, are recorded
at the  historical  cost when  originally  devoted to  service in the  regulated
businesses, as required by regulatory authorities.

         Maintenance and repairs of property and  replacements of minor items of
property are charged directly to maintenance  expense.  The original cost of the
regulated subsidiaries'  property,  plant and equipment retired, and the cost of
removal less salvage, are charged to accumulated depreciation.

         Oil and gas property acquisition, exploration and development costs are
capitalized  under the  full-cost  method  of  accounting.  All  costs  directly
associated with property acquisition, exploration and development activities are
capitalized,  up to certain  specified limits. If capitalized costs exceed these
limits at the end of any  quarter,  a  permanent  impairment  is  required to be
charged to earnings in that quarter.  Due to significant  declines in oil prices
in 1998,  Seneca's  capitalized  costs under the full-cost  method of accounting
exceeded  these  limits at March 31,  1998.  Seneca was required to recognize an
impairment  of its oil and gas  producing  properties in the quarter ended March
31, 1998. This charge amounted to $129.0 million (pretax) and reduced net income
for 1998 by $79.1 million.

Depreciation, Depletion and Amortization
Depreciation,  depletion and  amortization are computed by application of either
the  straight-line  method  or  the  units  of  production  method,  in  amounts
sufficient  to recover  costs over the  estimated  service  lives of property in
service,  and for oil  and gas  properties,  based  on  quantities  produced  in
relation to proved reserves (see discussion of change in method of depletion for
oil and gas properties  below).  The costs of unevaluated oil and gas properties
are excluded from this computation. For timber properties, depletion, determined
on a property by property  basis,  is charged to operations  based on the annual
amount of timber cut in relation to the total amount of recoverable  timber. The
provisions  for  depreciation,  depletion and  amortization,  as a percentage of
average depreciable property, were 4.3% in 1999, 4.4% in 1998 and 4.6% in 1997.

Cumulative Effect of Change in Accounting
Effective  October 1, 1997,  Seneca  changed its method of depletion for oil and
gas properties from the gross revenue method to the units of production  method.
The units of  production  method was  applied  retroactively  to prior  years to
determine the cumulative  effect through October 1, 1997. This cumulative effect
reduced earnings for 1998 by $9.1 million,  net of income tax.  Depletion of oil
and gas  properties for 1999 and 1998 was computed under the units of production
method.

         Pro forma amounts for 1998 and 1997 shown below, assume the retroactive
application of the new depletion method.

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


Gas Stored Underground - Current
Gas stored  underground  - current  is carried at lower of cost or market,  on a
last-in,  first-out  (LIFO) method.  Based upon the average price of spot market
gas purchased in September 1999,  including  transportation  costs,  the current
cost of replacing the inventory of gas stored  underground-current  exceeded the
amount  stated on a LIFO basis by  approximately  $51.4 million at September 30,
1999.

Unamortized Debt Expense
Costs  associated  with the  issuance of debt by the Company  are  deferred  and
amortized  over the  lives of the  related  issues.  Costs  associated  with the
reacquisition  of debt related to  rate-regulated  subsidiaries are deferred and
amortized  over the remaining  life of the issue or the life of the  replacement
debt in order to match regulatory treatment.

Foreign Currency Translation
The  functional  currency  for the  Company's  foreign  operations  is the local
currency.  The translation from the local currency to U. S. dollars is performed
for balance  sheet  accounts by using current  exchange  ratios in effect at the
balance  sheet date and, for revenue and expense  accounts,  by using an average
exchange  rate during the period.  The  resultant  cumulative  foreign  currency
translation   adjustment  is  recorded  as  a  component  of  Accumulated  Other
Comprehensive  Income in the Common  Stock  Equity  section of the  Consolidated
Balance Sheet.

Income Taxes
The Company and its domestic subsidiaries file a consolidated federal income tax
return.  Investment Tax Credit, prior to its repeal in 1986, was deferred and is
being  amortized  over the estimated  useful lives of the related  property,  as
required by regulatory  authorities having  jurisdiction.  No provision has been
made for domestic income taxes applicable to  undistributed  earnings of foreign
subsidiaries as the amounts are considered to be permanently  reinvested outside
the U.S.

Financial Instruments
Unrealized  gains or losses  from  "available-for-sale  securities"  (i.e.,  the
Company's  investments  in  marketable  equity  securities)  are  recorded  as a
component of Accumulated Other  Comprehensive  Income in the Common Stock Equity
section  of the  Consolidated  Balance  Sheet.  Reference  is  made  to Note F -
Financial Instruments for further discussion.

         Seneca  utilizes price swap agreements and options  (primarily  written
options) to manage a portion of the market risk associated with  fluctuations in
the price of natural gas and crude oil. NFR utilizes exchange-traded futures and
exchange-traded options to manage a portion of the market risk that it faces due
to fluctuations in the price of natural gas. Gains or losses from Seneca's price
swap agreements are accrued in operating revenues on the Consolidated  Statement
of   Income  at  the   contract   settlement   dates.   Seneca's   options   are
marked-to-market on a quarterly basis with gains or losses recorded in Operating
Revenues on the  Consolidated  Statement  of Income.  Gains or losses from NFR's
exchange-traded  futures  and  exchange-traded  options  are  recorded  in Other
Deferred  Credits on the  Consolidated  Balance Sheet until the hedged commodity
transaction  occurs, at which point they are reflected in operating  revenues on
the  Consolidated  Statement of Income.  Reference is made to Note F - Financial
Instruments for further discussion.

         In the  International  segment,  PSZT utilizes an interest rate swap to
eliminate  interest rate fluctuations on its variable rate debt. Gains or losses
are accrued in interest charges on the  Consolidated  Statement of Income at the
contract settlement dates.

Consolidated Statement of Cash Flows
For purposes of the Consolidated  Statement of Cash Flows, the Company considers
all highly liquid debt instruments  purchased with a maturity of generally three
months or less to be cash equivalents.  Interest paid in 1999, 1998 and 1997 was
$75.8 million, $46.2 million and $52.4 million, respectively.  Income taxes paid
in 1999,  1998 and 1997 were $35.0  million,  $64.5  million and $69.2  million,
respectively.

         Details of the stock  acquisitions  made by the Company during 1999 and
1998 are as follows:

         Further discussion of these acquisitions can be found at Note J - Stock
Acquisitions.

Earnings Per Common Share
Basic  earnings per common share is computed by dividing  income  available  for
common stock by the weighted average number of common shares outstanding for the
period.  Diluted earnings per common share reflects the potential  dilution that
could  occur  if  securities  or other  contracts  to issue  common  stock  were
exercised  or  converted  into  common  stock.  The  only  potentially  dilutive
securities the Company has outstanding are stock options.  The diluted  weighted
average  shares  outstanding  shown  on the  Consolidated  Statement  of  Income
reflects the potential dilution as a result of these stock options as determined
using the Treasury Stock Method.

New Accounting Pronouncements

Accounting for Derivative Instruments and Hedging Activities
In June 1998, the Financial  Accounting  Standards Board (FASB) issued Statement
of  Financial   Accounting   Standards  No.  133,   "Accounting  for  Derivative
Instruments and Hedging Activities" (SFAS 133). SFAS 133 establishes  accounting
and reporting standards for derivative instruments, including certain derivative
instruments  embedded  in other  contracts,  and for  hedging  activities.  This
statement  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.  The intended use of the  derivatives  and their  designation  as
either a fair value hedge, a cash flow hedge,  or a foreign  currency hedge will
determine  when the gains or losses on the  derivatives  are to be  reported  in
earnings and when they are to be reported as a component of other  comprehensive
income.

         Management  has  evaluated  the  derivatives  used by  Seneca,  NFR and
Horizon  and  believes  that the  adoption  of SFAS 133 will not have a material
impact on the  financial  condition  or results of  operations  of the  Company.
Management is continuing to evaluate other  financial  instruments and contracts
which may have  embedded  derivatives  that could be impacted by the adoption of
SFAS 133.  SFAS 133  required  the  Company to adopt the  standard  in the first
quarter  of fiscal  2000.  However,  in June  1999,  the FASB  issued  SFAS 137,
"Accounting for Derivative  Instruments and Hedging Activities - Deferral of the
Effective  Date of FASB  Statement No. 133." SFAS 137 delays,  by one year,  the
effective date of SFAS 133. Accordingly,  the Company will adopt SFAS 133 by the
first quarter of fiscal 2001.

(1)  Included in Other Deferred Credits on the Consolidated Balance Sheets.

         If for any reason  Distribution  Corporation  and/or Supply Corporation
ceases to meet the criteria for application of regulatory  accounting  treatment
for all or part of their  operations,  the  regulatory  assets  and  liabilities
related to those portions ceasing to meet such criteria would be eliminated from
the  balance   sheet  and  included  in  income  of  the  period  in  which  the
discontinuance of regulatory  accounting treatment occurs. Such amounts would be
classified as an extraordinary item.

New York Rate Settlements
With  respect to services  provided in New York,  Distribution  Corporation  has
entered into rate settlements with the NYPSC. The rate settlements provide for a
sharing  mechanism,  whereby  earnings  above a 12%  return on equity  are to be
shared equally between shareholders and ratepayers.  As a result of this sharing
mechanism,  Distribution  Corporation  had liabilities of $8.6 million and $10.7
million at September 30, 1999 and 1998,  respectively.  Of these  amounts,  $3.0
million was  reclassified  to Amounts Payable to Customers at September 30, 1999
and 1998 to reflect the amounts  estimated to be passed back to customers in the
following year.  Other aspects of the  settlements  include a special reserve of
$7.4 million  (including  interest of $0.2 million)  recorded  during 1999 to be
applied against Distribution  Corporation's incremental costs resulting from the
NYPSC's gas  restructuring  effort and a "refund  pool" of $3.5 million and $5.0
million at  September  30,  1999 and 1998,  respectively.  The refund pool is an
accumulation  of certain  refunds from upstream  pipeline  companies and certain
credits which can be used to offset  certain  specific  expense  items.  Various
other  regulatory  liabilities  have also been created through the New York rate
settlements  and amounted to $2.5 million and $6.6 million at September 30, 1999
and 1998, respectively.

         Regulatory   liabilities   representing  the  reduction  of  previously
recorded  deferred income taxes associated with  rate-regulated  activities that
are expected to be refundable  to customers  amounted to $14.8 million and $18.4
million at September 30, 1999 and 1998,  respectively.  Also, regulatory assets,
representing  future  amounts  collectible  from  customers,   corresponding  to
additional  deferred  income  taxes not  previously  recorded  because  of prior
ratemaking  practices  amounted to $87.7  million and $88.3 million at September
30, 1999 and 1998, respectively.

         The primary  issues related to Internal  Revenue  Service audits of the
Company for the years 1977-1994 were settled during March 1998 and the remaining
issues were settled in December 1998.  Net income for the years ended  September
30, 1999 and 1998 was increased by approximately  $3.9 million and $5.0 million,
respectively, as a result of interest, net of tax and other adjustments, related
to these settlements.

(1) The  availability  of consolidated  earnings  reinvested in the business for
    dividends payable in cash is limited under terms of the indentures  covering
    long-term  debt.  At  September  30,  1999,  $398.1  million of  accumulated
    earnings was free of such limitations.

Common Stock
The Company has various plans which allow shareholders,  customers and employees
to purchase shares of Company common stock. The Dividend  Reinvestment and Stock
Purchase Plan allows  shareholders  to reinvest cash dividends  and/or make cash
investments  in the Company's  common stock.  The Customer  Stock  Purchase Plan
provides  residential  customers the  opportunity  to acquire  shares of Company
common stock without the payment of any brokerage commissions or service charges
in connection  with such  acquisitions.  Effective  November 1, 1999,  these two
plans were  combined  into a new plan,  known as the National  Fuel Direct Stock
Purchase and Dividend  Reinvestment  Plan. The 401(k) Plans allow  employees the
opportunity to invest in Company common stock, in addition to a variety of other
investment  alternatives.  At the  discretion of the Company,  shares  purchased
under these plans are either original issue shares  purchased  directly from the
Company or shares purchased on the open market by an agent.

         The Company  also has a Director  Stock  Program  under which it issues
shares  of  Company  common  stock  to its  non-employee  directors  as  partial
consideration for their services as directors.

Shareholder Rights Plan
In 1996,  the Company's  Board of Directors  adopted a  shareholder  rights plan
(Plan). Effective April 30, 1999, the Plan was amended and is now embodied in an
Amended and Restated Rights Agreement.

         The holders of the  Company's  common stock have one right  (Right) for
each of their  shares.  Each Right,  which will  initially  be  evidenced by the
Company's  common stock  certificates  representing  the  outstanding  shares of
common  stock,  entitles the holder to purchase  one-half of one share of common
stock at a purchase price of $130 per share,  being $65 per half share,  subject
to adjustment (Purchase Price).

         The Rights become  exercisable  upon the  occurrence of a  distribution
date.  At any time  following a  distribution  date,  each holder of a Right may
exercise its right to receive  common stock (or,  under  certain  circumstances,
other  property of the  Company)  having a value equal to two times the Purchase
Price of the Right then in effect. However, the Rights are subject to redemption
or exchange by the Company prior to their exercise as described below.

         A distribution  date would occur upon the earlier of (i) ten days after
the public  announcement  that a person or group has  acquired,  or obtained the
right to acquire,  beneficial  ownership of the Company's  common stock or other
voting  stock  having  10% or more of the total  voting  power of the  Company's
common stock and other voting stock and (ii) ten days after the  commencement or
announcement  by a person or group of an  intention to make a tender or exchange
offer that would  result in that person  acquiring,  or  obtaining  the right to
acquire,  beneficial  ownership  of the  Company's  common stock or other voting
stock having 10% or more of the total voting power of the Company's common stock
and other voting stock.

         In certain  situations after a person or group has acquired  beneficial
ownership  of 10% or more of the total voting  power of the  Company's  stock as
described  above,  each  holder of a Right will have the right to  exercise  its
Rights to receive common stock of the acquiring  company having a value equal to
two times the Purchase Price of the Right then in effect. These situations would
arise if the Company is acquired in a merger or other business combination or if
50% or more of the Company's assets or earning power are sold or transferred.

         At any  time  prior to the end of the  business  day on the  tenth  day
following the announcement that a person or group has acquired,  or obtained the
right to acquire,  beneficial ownership of 10% or more of the total voting power
of the Company,  the Company may redeem the Rights in whole, but not in part, at
a price of $.01 per Right,  payable in cash or stock.  A decision  to redeem the
Rights requires the vote of 75% of the Company's full Board of Directors.  Also,
at any time following the announcement  that a person or group has acquired,  or
obtained the right to acquire,  beneficial ownership of 10% or more of the total
voting power of the Company,  75% of the  Company's  full Board of Directors may
vote to exchange  the Rights,  in whole or in part,  at an exchange  rate of one
share of common  stock,  or other  property  deemed to have the same value,  per
Right, subject to certain adjustments.

         After a distribution date, Rights that are owned by an acquiring person
will be null and  void.  Upon  exercise  of the  Rights,  the  Company  may need
additional  regulatory  approvals  to  satisfy  the  requirements  of the Rights
Agreement. The Rights will expire on July 31, 2008, unless they are exchanged or
redeemed earlier than that date.

         The  Rights  have   anti-takeover   effects  because  they  will  cause
substantial  dilution  of the common  stock if a person  attempts to acquire the
Company on terms not approved by the Board of Directors.

Stock Option and Stock Award Plans
The  Company  has various  stock  option and stock award plans which  provide or
provided  for the  issuance of one or more of the  following  to key  employees:
incentive stock options,  nonqualified stock options, stock appreciation rights,
restricted stock,  performance units or performance shares.  Stock options under
all plans have  exercise  prices  equal to the average  market  price of Company
common stock on the date of grant,  and generally no option is exercisable  less
than one year or more than ten years after the date of each grant.

         For the years ended  September 30, 1999, 1998 and 1997, no compensation
expense was  recognized  for options  granted  under these  plans.  Compensation
expense related to stock  appreciation  rights and restricted  stock under these
stock plans was $1.0 million,  $4.1 million and $8.1 million for the years ended
September 30, 1999, 1998 and 1997,  respectively.  Had compensation  expense for
stock options  granted  under the  Company's  stock option and stock award plans
been determined based on fair value at the grant dates, the Company's net income

         The fair value  amounts are not intended to reflect  principal  amounts
that the Company will ultimately be required to pay.

         Temporary cash investments, notes payable to banks and commercial paper
are stated at amounts which  approximate  their fair value due to the short-term
maturities of those  financial  instruments.  Investments  in life insurance are
stated at their cash  surrender  values as  discussed  below.  Investments  in a
mutual fund and the stock of an  insurance  company,  as  discussed  below,  are
stated at fair value based on quoted market prices.

Investments
Other assets includes cash surrender values of insurance  contracts and a mutual
fund  (accounted  for  as  an  "available-for-sale   security").  The  insurance
contracts and mutual fund were established as an informal funding  mechanism for
various  benefit  obligations  the  Company has to certain  employees.  The cash
surrender values of the insurance  contracts amounted to $44.2 million and $40.1
million at September 30, 1999 and 1998,  respectively.  The mutual fund amounted
to $5.0 million and $2.2 million at September 30, 1999 and 1998, respectively.

         Other  assets also  includes  shares of stock in an  insurance  company
which the Company  received as part of the insurance  company's  initial  public
offering in 1999. This  "demutualization" of the insurance company resulted in a
gain to the Company of $2.4  million.  At September  30, 1999,  the value of the
stock was $2.3  million.  The stock is accounted  for as an  "available-for-sale
security."

Derivative Financial Instruments
Seneca has entered into certain  price swap  agreements  and options to manage a
portion of the market risk associated with  fluctuations in the price of natural
gas and crude  oil in an  effort to  provide  more  stability  to its  operating
results.  These  agreements and options are not held for trading  purposes.  The
price swap agreements call for Seneca to receive monthly  payments from (or make
payment  to)  other  parties  based  upon the  difference  between a fixed and a
variable  price as specified by the  agreement.  The variable  price is either a
crude oil price quoted on the New York  Mercantile  Exchange or a quoted natural
gas price in "Inside FERC." These variable prices are highly correlated with the
market prices  received by Seneca for its natural gas and crude oil  production.
The fair value of  outstanding  natural gas and crude oil price swap  agreements
and options  discussed  below reflect the estimated  amounts Seneca would pay or
receive to terminate its derivative financial instruments at September 30, 1999.

         At  September  30, 1999,  Seneca had natural gas price swap  agreements
covering  a notional  amount of 40.2 Bcf  extending  through  2002 at a weighted
average  fixed  rate of $2.69 per Mcf.  Seneca  also had  crude  oil price  swap
agreements  covering a notional amount of 2,296,000 bbls extending  through 2001
at a weighted  average  fixed rate of $19.00 per bbl. The fair value of Seneca's
outstanding  natural gas and crude oil price swap  agreements  at September  30,
1999 was a net loss of  approximately  $9.8  million.  This  loss was  offset by
corresponding unrecognized gains from Seneca's anticipated natural gas and crude
oil production over the terms of the price swap agreements.

         Seneca  recognized net gains  (losses) of $2.6 million,  $(4.1) million
and $(21.5) million  related to settlements of its price swap agreements  during
1999,  1998 and 1997,  respectively.  As the  price  swap  agreements  have been
designated as hedges,  these gains (losses) were offset by  corresponding  gains
(losses) from Seneca's natural gas and crude oil production.

         At September 30, 1999, Seneca had the following options outstanding:



Type of Option                      Notional Amount                           Weighted Average Strike Price

Written Call Option                 184,000 bbls                              $18.00/bbl
Written Call Option                 2.6Bcf                                    $2.86/Mcf
Written Call Options(1)             13.9 Bcf or 732,000 bbls                  $2.62/Mcf or $18.00/bbl
Written Put Option                  916,000 bbls                              $12.50/bbl
Purchased Call Option               1,464,000 bbls                            $20.00/bbl



(1)The  counterparty  has a choice between a natural gas call option and a crude
   oil call  option,  depending  on  whichever  option has greater  value to the
   counterparty.

         As disclosed  in Note  A-Summary of  Significant  Accounting  Policies,
Seneca's  call and put options are being  marked-to-market.  The  mark-to-market
adjustment  for 1999 was a loss of $1.3  million,  the recording of which leaves
the fair value of the call and put options at  September  30, 1999 at a net loss
of $3.6  million.  During 1999,  Seneca paid the  counterparty  $28,000 and $1.2
million  related to the exercise of a portion of the written put options and the
written  call  options,  respectively.  Seneca  received  $0.6  million from the
counterparty  related to  Seneca's  exercise  of a portion of the $20.00 per bbl
call options that it had purchased.

         The Company is exposed to credit risk on the price swap agreements that
Seneca  has  entered  into  as well  as on the  call  options  that  Seneca  has
purchased.  Credit risk relates to the risk of loss that the Company would incur
as a result of nonperformance  by counterparties  pursuant to the terms of their
contractual  obligations.  To mitigate such credit risk,  management  performs a
credit  check,  and  then  on an  ongoing  basis  monitors  counterparty  credit
exposure.

         NFR utilizes  exchange-traded  futures and  exchange-traded  options to
manage a portion of the market risk associated with fluctuations in the price of
natural  gas.  Such  futures and options are not held for trading  purposes.  At
September 30, 1999,  NFR had natural gas futures  contracts  covering 2.1 Bcf of
gas on a net basis extending  through 2001 at a weighted  average contract price
of $2.75 per Mcf. NFR had sold natural gas options covering 17.1 Bcf of gas at a
weighted  average strike price of $3.01 per Mcf. NFR also had purchased  natural
gas options  covering 9.0 Bcf of gas at a weighted average strike price of $2.72
per Mcf. The  exchange-traded  futures and  exchange-traded  options are used to
hedge NFR's purchase and sale  commitments  and storage gas inventory.  The fair
value of NFR's outstanding  exchange-traded  futures and exchange-traded options
at September 30, 1999 was a net gain of  approximately  $1.1 million.  This fair
value  reflects the estimated net amount that NFR would receive to terminate its
exchange-traded futures and exchange-traded options at September 30, 1999. Since
these exchange-traded  futures contracts and exchange-traded options qualify and
have been designated as hedges,  any gains or losses resulting from market price
changes would be substantially offset by the related commodity transaction.

         NFR recognized net gains (losses) of $(5.4)  million,  $1.3 million and
$1.7 million  related to futures  contracts  and options  during 1999,  1998 and
1997,  respectively.  Since these futures contracts and options qualify and have
been designated as hedges, these net gains (losses) were substantially offset by
the related commodity transactions.

         PSZT  utilizes  an  interest  rate  swap  to  eliminate  interest  rate
fluctuations on its CZK 1,595,924,000  term loan ($47.7 million at September 30,
1999),  which carries a variable  interest rate of six month PRIBOR plus 0.475%.
Under the terms of the interest rate swap, which extends until 2001, PSZT pays a
fixed  rate of 8.31% and  receives  a floating  rate of six month  PRIBOR.  PSZT
recognized  a loss of $0.1  million  related to this  interest  rate swap during
1999.  The fair value of PSZT's  interest  rate swap at September 30, 1999 was a
loss of approximately $1.0 million.

Note G - Retirement Plan and Other Post-Retirement Benefits

The Company has a  tax-qualified,  noncontributory,  defined-benefit  retirement
plan (Retirement Plan) that covers  substantially all domestic  employees of the
Company.  The Company  provides  health  care and life  insurance  benefits  for
substantially  all domestic retired  employees under a  post-retirement  benefit
plan (Post-Retirement Plan).

         The Company's  policy is to fund the  Retirement  Plan with at least an
amount necessary to satisfy the minimum funding  requirements of applicable laws
and  regulations  and not more than the maximum  amount  deductible  for federal
income  tax  purposes.   The  Company  has  established   Voluntary   Employees'
Beneficiary   Association   (VEBA)   trusts   for  its   Post-Retirement   Plan.
Contributions  to the VEBA  trusts are tax  deductible,  subject to  limitations
contained in the  Internal  Revenue  Code and  regulations  and are made to fund
employees'  post-retirement  health care and life insurance benefits, as well as
benefits   as  they  are  paid  to  current   retirees.   Retirement   Plan  and
Post-Retirement  Plan  assets  primarily  consist  of equity  and  fixed  income
investments and/or units in commingled funds or money market funds.

         Distribution  Corporation and Supply  Corporation are fully  recovering
their net periodic pension and post-retirement  benefit costs in accordance with
the applicable  regulatory  commission  authorization.  For financial  reporting
purposes,  Distribution Corporation and Supply Corporation record the difference
between the amounts of pension cost and post-retirement benefit cost recoverable
in rates and the  amounts of such costs as  determined  by their  actuary  under
applicable accounting  principles as either a regulatory asset or liability,  as
appropriate.  Pension  and  post-retirement  benefit  costs  reflect  the amount
recovered from customers in rates during the year.  Under the NYPSC's  policies,
Distribution Corporation segregates the amount of such costs collected in rates,
but not yet  contributed  to the Retirement and  Post-Retirement  Plans,  into a
regulatory  liability  account.  This  liability  accrues  interest at the NYPSC
mandated  interest  rate and this  interest  cost is  included  in  pension  and
post-retirement  benefit costs.  For purposes of disclosure,  the liability also
remains in the disclosed  pension and  post-retirement  benefit liability amount
because it has not yet been contributed.

         The effect of the  discount  rate  change in 1999 was to  decrease  the
Benefit  Obligation by $9.1  million.  The effect of the discount rate change in
1998 was to increase the Benefit Obligation by $25.3 million.

         The annual rate of  increase in the per capita cost of covered  medical
care  benefits  was assumed to be 10% for 1997,  9% for 1998 and 8% for 1999 and
gradually  decline to 5.5% by the year 2003 and  remain  level  thereafter.  The
annual  rate of increase  for  medical  care  benefits  provided  by  healthcare
maintenance  organizations  was  assumed  to be 7.5% in  1998,  7.0% in 1999 and
gradually  decline to 5.5% by the year 2002 and  remain  level  thereafter.  The
annual  rate of increase  in the per capita  cost of covered  prescription  drug
benefits  was  assumed to be 8.5% for 1997,  9.0% for 1998 and 8.0% for 1999 and
gradually  decline to 5.5% by the year 2003 and  remain  level  thereafter.  The
annual rate of  increase in the per capita  Medicare  Part B  Reimbursement  was
assumed  to be 3.1% for  1997,  9.0%  for  1998 and 8.0% for 1999 and  gradually
decline to 5.5% by the year 2003 and remain level thereafter.

         The health care cost trend rate  assumptions  used to calculate the per
capita cost of covered  medical care benefits  have a significant  effect on the
amounts  reported.  If the health care cost trend rates were  increased by 1% in
each year,  the Benefit  Obligation  as of October 1, 1999 would be increased by
$38.9  million.  This 1% change would also have  increased  the aggregate of the
service and interest  cost  components of net periodic  post-retirement  benefit
cost  for 1999 by $4.0  million.  If the  health  care  cost  trend  rates  were
decreased by 1% in each year, the Benefit Obligation as of October 1, 1999 would
be decreased by $34.0  million.  This 1% change  would also have  decreased  the
aggregate  of  the  service  and  interest  cost   components  of  net  periodic
post-retirement benefit cost for 1999 by $3.4 million.

Note H - Commitments and Contingencies

Environmental Matters
It is the Company's  policy to accrue  estimated  environmental  clean-up  costs
(investigation  and  remediation)  when such amounts can reasonably be estimated
and it is  probable  that the  Company  will be  required  to incur such  costs.
Distribution  Corporation and Supply  Corporation  have estimated their clean-up
costs related to the sites  described below in (i) and (ii) will be in the range
of $9.4 million to $10.4 million. The minimum liability of $9.4 million has been
recorded on the  Consolidated  Balance Sheet at September  30, 1999.  Other than
discussed below,  the Company is currently not aware of any material  additional
exposure to environmental liabilities. However, adverse changes in environmental
regulations or other factors could impact the Company.

         The Company has been  recovering  site  investigation  and  remediation
costs in rates.  Accordingly,  the  Consolidated  Balance Sheet at September 30,
1998 included related regulatory assets of $12.4 million.  Over the past several
years, the Company has been negotiating  settlements with its insurance carriers
related to  environmental  investigation  and  remediation  costs.  The  Company
received net proceeds of  approximately  $9.8 million in 1999 and  approximately
$3.5 million in 1998  related to these  settlements.  In  addition,  the Company
reached a settlement  with one of its insurance  carriers for  reimbursement  of
covered costs to remediate certain sites. A portion of the net proceeds received
and  future  proceeds   accrued  have  been  applied  to  reduce  the  Company's
environmental related regulatory assets to zero at September 30, 1999.

         The  Company is subject  to various  federal,  state and local laws and
regulations  relating  to the  protection  of the  environment.  The Company has
established  procedures for the ongoing evaluation of its operations to identify
potential  environmental  exposures  and comply  with  regulatory  policies  and
procedures.

         (i)  Former Manufactured Gas Plant and Former Gasoline Plant Sites

         Distribution Corporation has incurred or is incurring clean-up costs at
five  former  manufactured  gas  plant  sites  in  New  York  and  Pennsylvania.
Remediation is complete at one site and substantially complete at a second site.
With respect to the second site, Distribution Corporation has been designated by
the New York  Department of  Environmental  Conservation  (DEC) as a potentially
responsible  party (PRP) and is also engaged in litigation  with the DEC and the
party who bought that site from  Distribution  Corporation's  predecessor.  At a
third site,  the remedial plan has been approved by the DEC and  remediation  is
expected to begin in 2000.  A fourth site is in an ongoing  investigation  stage
with remediation being designed. The fifth is a site allegedly containing, among
other things,  manufactured gas plant waste and is in the  investigation  stage.
Supply  Corporation is in the final stages of  remediation of a former  gasoline
plant site.

         (ii)  Third Party Waste Disposal Sites

         Distribution  Corporation  and Supply  Corporation  are each  currently
identified by the DEC or the Federal Environmental Protection Agency as one of a
number of companies considered to be PRPs with respect to certain waste disposal
sites in New York which were operated by unrelated  third parties.  The PRPs are
alleged to have  contributed  to the materials  that may have been  collected at
such  waste  disposal  sites  by  the  site  operators.  The  ultimate  cost  to
Distribution  Corporation or Supply  Corporation with respect to the remediation
of these sites will depend on such factors as the remediation plan selected, the
extent of site contamination, the number of additional PRPs at each site and the
portion of  responsibility,  if any,  attributed to Distribution  Corporation or
Supply  Corporation.  Distribution  Corporation  is a PRP at two waste  disposal
sites.  The  remediation  has been completed at one site and the remedial design
selected at the second site.  Supply  Corporation is a PRP at one waste disposal
site, which is at the investigation stage.

         Without being named a PRP,  Distribution  Corporation has also signed a
consent  decree  (court  approval  pending) by which it would share the costs of
remediating  another waste disposal site in New York. Also without being named a
PRP, Supply  Corporation  expects that it will participate in the cost of a site
that is currently being remediated by a third party.

         (iii)  Other Sites

         Distribution  Corporation  received, in 1998 and again in October 1999,
notice  that  the DEC  believes  Distribution  Corporation  is  responsible  for
contamination  discovered at an additional former manufactured gas plant site in
New  York  (without  naming  Distribution  Corporation  as a PRP).  Distribution
Corporation   responded   that  other   companies   operated  that  site  before
Distribution Corporation's predecessor did, that liability could be imposed upon
Distribution  Corporation  only if hazardous  substances were disposed of at the
site during a period when the site was  operated by  Distribution  Corporation's
predecessor, and that Distribution Corporation was unaware of any such disposal.
Distribution  Corporation  has not incurred any clean-up  costs at this site nor
has it been able to reasonably  estimate the  probability or extent of potential
liability.

         Distribution  Corporation  understands that PRPs at another third party
waste  disposal  site  have  obtained  records  from the  operator  (a waste oil
collector)  indicating  that  the  site  received  used  oil  from  Distribution
Corporation (among others). A contribution claim could,  therefore,  be asserted
against Distribution  Corporation,  which has not incurred any clean-up costs at
this site nor been able to  reasonably  estimate  the  probability  or extent of
potential liability.

         Supply  Corporation  believes that there is the possibility that it may
incur costs related to certain of its  measuring  and regulator  stations in New
York. No costs have been  incurred or accrued to date.  Supply  Corporation  has
estimated its exposure at approximately $0.2 million.

         (iv)  Clean Air Standards

         The Company, in its international  operations in the Czech Republic has
substantially  completed the  construction of new  fluidized-bed  boilers at the
district  heating  and power  generation  plant of PSZT in order to comply  with
certain clean air standards mandated by the Czech Republic  government.  Capital
expenditures  related  to this  reconstruction  incurred  by  PSZT in 1999  were
approximately $23.0 million.

Other
The Company has entered into  contractual  commitments in the ordinary course of
business including commitments by Distribution  Corporation to purchase capacity
on  nonaffiliated  pipelines to meet customer gas supply needs.  The majority of
these contracts  (representing 88% of current contracted demand capacity) expire
within the next five years.  Costs incurred under these  contracts are purchased
gas costs,  subject  to state  commission  review,  and are being  recovered  in
customer rates through inclusion in Distribution  Corporation's  rate schedules.
Management believes,  to the extent any stranded pipeline costs are generated by
the unbundling of services in Distribution Corporation's service territory, such
costs will be recoverable from customers.

         The Company is involved in  litigation  arising in the normal course of
its  business.  In  addition to the  regulatory  matters  discussed  in Note B -
Regulatory Matters,  the Company is involved in other regulatory matters arising
in the normal  course of business  that involve  rate base,  cost of service and
purchased  gas cost issues.  While the  resolution  of such  litigation or other
regulatory  matters  could have a material  effect on earnings and cash flows in
the  year of  resolution,  none of this  litigation,  and  none of  these  other
regulatory  matters,  are  expected  to have a  material  adverse  effect on the
financial condition of the Company at this time.

Note I - Business Segment Information

The Company has adopted SFAS 131,  "Disclosures  About Segments of an Enterprise
and Related  Information"  (SFAS 131), which changes the way the Company reports
information about its business segments. SFAS 131 requires disclosure of certain
financial information based upon how management evaluates the performance of its
business segments.  The information for 1998 and 1997 has been restated from the
prior year's presentation to conform to the 1999 presentation.

         The Company has six reportable segments: Utility, Pipeline and Storage,
Exploration  and Production,  International,  Energy  Marketing and Timber.  The
breakdown of the Company's  reportable  segments is based upon a combination  of
factors including differences in products and services,  regulatory  environment
and geographic factors.

         The Utility segment operations are regulated by the NYPSC and the PaPUC
and are carried out by Distribution Corporation.  Distribution Corporation sells
natural gas to retail customers and provides natural gas transportation services
in western New York and northwestern Pennsylvania.

         The Pipeline and Storage  segment  operations are regulated by the FERC
and are carried out by Supply Corporation and SIP. Supply Corporation transports
and stores  natural  gas for  utilities  (including  Distribution  Corporation),
natural gas marketers (including NFR) and pipeline companies in the northeastern
United States markets.  SIP,  although not regulated itself by the FERC, holds a
one-third  partnership  interest in the  Independence  Pipeline  Company,  whose
rates, services and other matters will be regulated by the FERC.

         The Exploration and Production  segment,  through Seneca, is engaged in
exploration  for, and  development and purchase of, natural gas and oil reserves
in the Gulf Coast of Texas and Louisiana,  in California,  in Wyoming and in the
Appalachian  region of the United States.  Seneca's  production is, for the most
part, sold to purchasers located in the vicinity of its wells.

         The  International  segment's  operations  are  carried out by Horizon.
Horizon  engages  in foreign  energy  projects  through  the  investment  of its
indirect subsidiaries as the sole or partial owner of various business entities.
Horizon's   current   emphasis  is  the  Czech  Republic   where,   through  its
subsidiaries,  it owns majority  interests in companies  having district heating
and  power  generation  plants  in the  northern  Bohemia  region  of the  Czech
Republic.

         The Energy Marketing segment is comprised of NFR's  operations.  NFR is
engaged in the retail  marketing of natural gas, the  marketing of  electricity,
and the performance of energy  management  services for industrial,  commercial,
public authority and residential  end-users  located in the northeastern  United
States.

         The  Timber  segment's  operations  are  carried  out by the  Northeast
division of Seneca and by  Highland.  This  segment  has timber  holdings in the
northeastern United States and several sawmills and kilns in Pennsylvania.

         The data presented in the tables below reflect the reportable  segments
and  reconciliations  to consolidated  amounts.  The accounting  policies of the
segments  are the same as those  described  in Note A - Summary  of  Significant
Accounting  Policies.  Sales of products or services between segments are billed
at  regulated  rates  or  at  market  rates,  as  applicable.  Expenditures  for
long-lived assets include additions to property,  plant and equipment and equity
investments in corporations (stock acquisitions) and/or partnerships, net of any
cash acquired.  The Company evaluates segment performance based on income before
discontinued  operations,  extraordinary items and cumulative effects of changes
in  accounting  (when  applicable).  When these  items are not  applicable,  the
Company evaluates performance based on net income.

Note J - Stock Acquisitions

Exploration and Production
In May 1998, Seneca acquired the outstanding  shares of HarCor for approximately
$32.6 million.  The  acquisition of HarCor was accounted for in accordance  with
the purchase method.  HarCor's results of operations were  incorporated into the
Company's  consolidated  financial  statements for the period  subsequent to the
completion of the tender offer in May 1998.  Effective  August 31, 1999,  HarCor
was merged into Seneca.

International
During 1998, Horizon, through a wholly-owned subsidiary, increased its ownership
interest in SCT from 36.8% at September 30, 1997 to 82.7% at September 30, 1998.
The cost of acquiring these additional shares was  approximately  $24.9 million.
Also in 1998, Horizon invested in PSZT, and owned an 86.2% interest at September
30,  1998.  The cost of  acquiring  the shares of PSZT was  approximately  $64.5
million.

         During 1999, Horizon, through a wholly-owned subsidiary,  increased its
ownership  interest in SCT to 82.87% for a minimal cost.  SCT in turn  increased
its ownership in JTR, a district heating plant in the northern Bohemia region of
the Czech Republic,  from 34% to 65.78%.  The cost of acquiring these additional
shares was approximately $5.8 million.

         The acquisitions made in the International  segment have been accounted
for in accordance with the purchase  method.  The goodwill  resulting from these
acquisitions  is being  amortized  over a  twenty-year  period.  The goodwill is
recorded in Other  Assets in the  Company's  Consolidated  Balance  Sheet.  This
goodwill  amounted to $9.5 million and $10.1  million at September  30, 1999 and
1998, respectively.

Note K - Quarterly Financial Data (unaudited)

In the opinion of management,  the following quarterly  information includes all
adjustments necessary for a fair statement of the results of operations for such
periods.  Per common share  amounts are  calculated  using the weighted  average
number of shares outstanding during each quarter.  The total of all quarters may
differ from the per common share amounts shown on the Consolidated  Statement of
Income.  Those per common share amounts are based on the weighted average number
of shares outstanding for the entire fiscal year. Because of the seasonal nature
of  the  Company's  heating  business,   there  are  substantial  variations  in
operations reported on a quarterly basis.

Reserve Quantity Information (unaudited)
The Company's proved oil and gas reserves are located in the United States.  The
estimated  quantities of proved reserves  disclosed in the table below are based
upon estimates by qualified Company  geologists and engineers and are audited by
independent petroleum engineers. Such estimates are inherently imprecise and may
be subject to substantial  revisions as a result of numerous factors  including,
but  not  limited  to,  additional  development  activity,  evolving  production
history, and continual reassessment of the viability of production under varying
economic conditions.

Standardized  Measure of Discounted Future Net Cash Flows Relating to Proved Oil
and Gas Reserves (unaudited)
The Company cautions that the following presentation of the standardized measure
of  discounted  future net cash flows is intended to be neither a measure of the
fair market value of the  Company's oil and gas  properties,  nor an estimate of
the  present  value of actual  future  cash flows to be  obtained as a result of
their  development  and  production.  It is based upon  subjective  estimates of
proved  reserves only and  attributes  no value to categories of reserves  other
than proved  reserves,  such as probable  or possible  reserves,  or to unproved
acreage. Furthermore, it is based on year-end prices and costs adjusted only for
existing  contractual changes, and it assumes an arbitrary discount rate of 10%.
Thus, it gives no effect to future price and cost changes certain to occur under
the widely fluctuating political and economic conditions of today's world.

         The  standardized  measure  is  intended  instead to provide a somewhat
better means for comparing the value of the Company's proved reserves at a given
time with those of other oil- and gas-producing  companies than is provided by a
simple comparison of raw proved reserve quantities.
