PART I
------

Certain statements included in this Annual Report on Form 10-K are
forward-looking statements as defined in Section 21E of the Securities Exchange
Act of 1934 that involve risk and uncertainty, including the improvement in
Holdings and Niagara Mohawk's cash flow upon the implementation of the MRA and
PowerChoice, the timing and outcome of the proposed future sale of Niagara
Mohawk's remaining fossil and nuclear generation assets, the planned repayment
of debt, the effects of Niagara Mohawk's transition to a new customer service
system, and the collection of accounts receivable and the corresponding bad debt
expense. These forward-looking statements are based upon a number of
assumptions, including assumptions regarding PowerChoice and regulatory actions
to continue to support such an agreement. Actual future results and
developments may differ materially depending on a number of factors, including
regulatory changes either by the federal government or the PSC, uncertainties
regarding the ultimate impact on Holdings and Niagara Mohawk as the regulated
electric and gas industries are further deregulated and electricity and gas
suppliers gain open access to Niagara Mohawk's retail customers, challenges to
PowerChoice under New York laws, the timing and extent of changes in commodity
prices and interest rates, the effects of weather, the length and frequency of
outages at Niagara Mohawk's two nuclear plants, the results from Niagara
Mohawk's proposed sale of its generation assets, the effects of transition to a
new customer service system, including efforts made by Niagara Mohawk to collect
from customers, and the economic conditions of Niagara Mohawk's service
territory.

ITEM 1. BUSINESS

On March 18, 1999, Niagara Mohawk Power Corporation ("Niagara Mohawk") was
reorganized into a holding company structure in accordance with its Agreement
and Plan of Exchange between Niagara Mohawk and Niagara Mohawk Holdings, Inc.
("Holdings"). Niagara Mohawk's outstanding common stock was exchanged on a
share-for-share basis for Holdings' common stock. Niagara Mohawk's preferred
stock and debt were not exchanged as part of the share exchange and continue as
shares and debt of Niagara Mohawk. In addition, to further complete the holding
company structure, Niagara Mohawk, on March 31, 1999, distributed its ownership
in the stock of Opinac North America, Inc. ("Opinac") as a dividend to Holdings.
As a result, Holdings has two subsidiaries, (1) Niagara Mohawk, which is
primarily a regulated electric and gas utility, and (2) Opinac, which is mainly
involved in unregulated activities in the energy business. Opinac and its
subsidiaries consist of an energy marketing company, and have investments in
energy related and services businesses, a development stage telecommunications
company (Telergy, Inc.), and a research and development company (EVonyx, Inc.)
that has developed and intends to commercialize new fuel cell and battery
technology.

Holdings was organized in 1998 under the laws of New York State. Niagara Mohawk
was organized in 1937 under the laws of New York State and is engaged
principally in the regulated energy delivery business in New York State.
Niagara Mohawk provides electric service, and sells, distributes, and transports
natural gas to approximately 1,600,000 electric and 540,000 gas customers in
areas of central, northern and western New York State. Niagara Mohawk comprises
98% of Holdings' total assets and 94% of Holdings' total revenues. See Part II,
Item 8. Financial Statements and Supplementary Data - Note 11. - Segment
Information.

GENERAL
-------

Until recent years, the electric and gas utility industry operated in a
relatively stable business environment, subject to traditional cost-of-service
regulation. The investment community, both shareholders and creditors,
considered utility securities to be of low risk and high quality. Regulators
upheld the utilities' rights to provide service in its franchise areas in
exchange for the utility company's obligation to provide universal service to
customers in its service territory, subject to cost-of-service regulation. Such
regulation often encouraged regulators and other governmental bodies to use
utilities as vehicles to advance social programs and collect taxes. In general,
prices were established based on cost-of-service, including a fair rate of
return and utilities were allowed to fully recover all prudently incurred costs.
Cash flows were relatively predictable, as was the industry's ability to sustain
dividend payout and interest coverage ratios.

Consequently, Niagara Mohawk's past electricity and gas prices reflected
traditional utility regulation. As such, Niagara Mohawk's electricity prices
have included both state-mandated purchased power costs from IPPs, at costs far
exceeding Niagara Mohawk's actual avoided costs, and the costs of high taxes in
the state of New York. Avoided costs are the costs Niagara Mohawk would
otherwise incur to generate power if it did not purchase electricity from
another source.

While Niagara Mohawk was experiencing rising prices, rapid technological
advances have significantly reduced the price of new generation and
significantly improved the performance of smaller scale generation units.
Actions taken by other utilities throughout the country to lower their prices,
including those in areas with already relatively low prices, increased the
threat of industrial relocation and the need to offer discounts to industrial
customers.

Recognizing the competitive trends in the electric utility industry and the
impracticability of remedying the situation through a series of customer rate
increases, in mid-1996, Niagara Mohawk began comprehensive negotiations to
terminate, amend or restate a substantial portion of above market PPAs in an
effort to mitigate the escalating cost of these PPAs as well as to prepare
Niagara Mohawk for a more competitive environment. These negotiations led to
the MRA and the PowerChoice agreement.

In 1998, Niagara Mohawk finalized these agreements and believes that they will
significantly improve its financial outlook. Niagara Mohawk and the PSC agreed
to a five-year rate plan and Niagara Mohawk agreed to divest its fossil and
hydro generation assets, representing 4,217 MW of capacity and approximately
$1.0 billion of net book value.

As part of the MRA, Niagara Mohawk terminated during 1998, 18 PPAs for 1,092 MW,
restated 8 PPAs for 535 MW and amended one PPA for 42 MW in exchange for $3.934
billion in cash and 20.5 million shares of Niagara Mohawk common stock.
Management believes that the MRA and the PowerChoice agreement provide Niagara
Mohawk with financial stability and create an improved platform from which to
build value. The primary objective of the MRA was to convert a large and
growing off-balance sheet payment obligation that threatened the financial
viability of Niagara Mohawk into a fixed and manageable capital obligation. The
lower contractual obligations resulting from the MRA significantly improved cash
flow which is primarily dedicated to reduce indebtedness incurred to fund the
MRA. With the improved cash flow and proceeds from the generation asset sales,
Niagara Mohawk redeemed approximately $1.1 billion in debt during 1999. With
the PowerChoice agreement, Niagara Mohawk has lowered prices beginning on
September 1, 1998, for its industrial, commercial and residential electric
customers for a period of three years, and provides reasonable certainty of
prices for the years thereafter. The PowerChoice agreement and the MRA also
facilitate the creation of a competitive electricity supply market in Niagara
Mohawk's service territory. Niagara Mohawk is actively pursuing other
opportunities to reduce its payments to IPPs that were not party to the MRA.

A major priority during 1999 was to complete the work begun in 1998. During
1999, Niagara Mohawk completed the sale of its coal-fired generation plants, its
hydroelectric generation plants, and its oil and gas-fired generation plant in
Oswego. During 1999, Niagara Mohawk also announced an agreement to sell its oil
and gas-fired generation plant in Albany and entered into an agreement to sell
its ownership share of the Roseton oil and gas-fired plant by no later than
January 1, 2003. In addition, Niagara Mohawk announced in June 1999 an
agreement to sell its nuclear assets. The sale is contingent upon Niagara
Mohawk receiving the necessary regulatory approvals, and management cannot
determine at this time whether a sale will occur. Niagara Mohawk's nuclear
assets are still being recovered under cost-of-service rates.

Also during 1999, Niagara Mohawk completed the transition of all customers to
retail access. This means that all of Niagara Mohawk's customers are now able
to choose both their electricity and gas supplier. On September 1, 1999,
Niagara Mohawk implemented its second phase of rate reductions, as outlined in
its PowerChoice agreement.

The transition to the holding company structure was also completed during 1999.
The holding company structure is intended to provide Holdings and its
subsidiaries with the financial and regulatory flexibility to compete more
effectively in an increasingly competitive energy industry by providing a
structure that can accommodate both regulated and unregulated lines of business.
The holding company structure will permit Holdings to participate in unregulated
business opportunities as the industry evolves.

In the near term, Holdings and Niagara Mohawk believe the greatest opportunity
for improving its financial condition will come from paying down debt and
repurchasing Holdings' common stock. During 1999, Niagara Mohawk repaid
approximately $1.1 billion in debt and repurchased 10 million shares of
Holdings' common stock. Niagara Mohawk will continue to emphasize operational
excellence and seek to improve margins through cost reductions. In addition,
Holdings intends to pursue unregulated business opportunities through Opinac.

For a discussion of events that occurred during 1999, including the
restructuring of the regulated electric utility business, other federal and
state regulatory initiatives, and Niagara Mohawk's efforts to address
deregulation and its financial condition, see Part II, Item 7. Management's
Discussion and Analysis of Financial Condition and Results of Operations.

REGULATION AND RATES
--------------------

Several critical initiatives have been undertaken by various regulatory bodies
and Niagara Mohawk that have had, and are likely to continue to have, a
significant impact on the shape of Niagara Mohawk and the utility industry. See
Part II, Item 7. Management's Discussion and Analysis of Financial Condition and
Results of Operations - PowerChoice and the Restructuring of the Regulated
Electric Utility Business, Other Federal and State Regulatory Initiatives for a
discussion of these initiatives.

Analysis of Financial Condition and Results of Operations - Other Federal and
State Regulatory Initiatives - Gas Multi-Year Rate and Restructuring Proposal.

ELECTRIC SUPPLY PLANNING
------------------------

Under the PowerChoice agreement, the PSC approved Niagara Mohawk's plan to
divest its fossil and hydro generation assets, which is a key component in its
PowerChoice agreement to lower average electricity prices and provide customer
choice. During 1999, Niagara Mohawk completed the sale of its coal-fired
generation assets, its hydro generation assets, and its oil and gas-fired plant
at Oswego. During 1999, Niagara Mohawk also announced agreements to sell its
oil and gas-fired plant at Albany and its nuclear generation assets. The sale
of the nuclear assets is uncertain, because it is subject to significant
regulatory approval. See Part II, Item 8. Financial Statements and
Supplementary Data - Note 3. - Nuclear Operations. Niagara Mohawk has also
signed an agreement to sell its interest in the Roseton oil and gas-fired
generation plant. As a result of these generation asset sales, Niagara Mohawk
has entered into various agreements to purchase its power needs from the buyers
of the generation assets. Niagara Mohawk will purchase any additional power
needs on the open market through the NYISO. The NYISO commenced operations
in December 1999 as a result of a FERC ruling which promotes competition by
requiring public utilities owning, operating, or controlling interstate
transmission facilities to file tariffs which offer others the same
transmission services they provide for themselves, under comparable terms and
conditions. One result of the formation of the NYISO was the dissolution of
the NYPP. See the "Purchased Power" discussion below for a description of the
various types of power purchase agreements. For a discussion of the results of
the generation asset sales to date, the status of the pending generation asset
sales, a discussion of the formation of the NYISO, and a discussion of power
contracts, see Part II, Item 7. Management's Discussion and Analysis of
Financial Condition and Results of Operations - PowerChoice and the
Restructuring of the Regulated Electric Utility Business - Generation Asset
Sales, and FERC Order 888 - Open Access and Item 8. Financial Statements and
Supplementary Data - Note 8. - Commitments and Contingencies and Note 9. - Fair
Value of Financial and Derivative Financial Instruments.

PURCHASED POWER
---------------

As a result of Niagara Mohawk's ongoing divestiture of its generation assets,
Niagara Mohawk will need to rely more on purchases of electricity from external
sources. Niagara Mohawk has entered into agreements to purchase a portion of
its energy needs and will purchase any remaining needs through purchase options
or the open market through the NYISO. See Part II, Item 8. Financial Statements
and Supplementary Data - Note 8. - Commitments and Contingencies - Long-Term
Contracts for the Purchase of Electric Power, for a further discussion of these
commitments. Niagara Mohawk has also entered into several financial agreements
to hedge the price of electricity. See Part II, Item 8. Financial Statements
and Supplementary Data - Note 9. - Fair Value of Financial and Derivative
Financial Instruments for a discussion of these agreements. The following is a
summary of Niagara Mohawk's main sources of purchased power:

POWER PURCHASE AGREEMENTS (PPAs)
- --------------------------------
- - PURPA CONTRACTS: In 1999, Niagara Mohawk purchased 6,768,000 MWh or about
18% of its total power supply from IPPs, which is a 30% reduction from 1998.
This amount includes payments to the IPP Parties under put contracts as
described in more detail below. For a discussion of Niagara Mohawk's efforts
to reduce its IPP costs, see Item 3. Legal Proceedings; Part II, Item 7.
Management's Discussion and Analysis of Financial Condition and Results of
Operations - PowerChoice and the Restructuring of the Regulated Electric
Utility Business; and Part II, Item 8. Financial Statements and Supplementary
Data - Note 2. - Rate and Regulatory Issues and Contingencies, Note 8. -
Commitments and Contingencies - Long-Term Contracts for the Purchase of
Electric Power and Note 9. - Fair Value of Financial and Derivative Financial
Instruments.

- - PUT CONTRACTS: As a part of the MRA, Niagara Mohawk signed put agreements
with approximately one-third of the IPP Parties whereby the IPP Parties have
an option to put the physical delivery of energy to Niagara Mohawk at market
prices. These put agreements will be in effect until the NYISO meets certain
volume and capacity conditions for a consecutive six-month period. During
1999, Niagara Mohawk purchased from the IPP Parties 2,782,000 MWh or about 7%
of its total supply of electric power received as part of these put
agreements.

- - FOSSIL/HYDRO CONTRACTS: As part of the sale of Niagara Mohawk's fossil
and hydro generation assets, Niagara Mohawk entered into agreements with the
buyers of these assets for the purchase of capacity and energy. During 1999,
these purchases amounted to 3,490,000 MWh or about 9% of Niagara Mohawk's
total power supply requirements. These purchases became effective at the
time each of the asset sales were completed. The contracts with the buyers
of the coal-fired generation plant converted to financial agreements upon
the start up of the NYISO. The agreement signed as part of the sale of the
Albany oil and gas-fired generation plant is a financial agreement. See Part
II, Item 8. Financial Statements and Supplementary Data - Note 8. -
Commitments and Contingencies - Long-Term Contracts for the Purchase of
Electric Power, for a further discussion of these PPAs.

- - NUCLEAR CONTRACTS: If Niagara Mohawk is successful in selling its nuclear
assets, Niagara Mohawk anticipates it would enter into PPAs to purchase
energy and capacity at negotiated prices. The negotiated prices may be above
projected market prices during the term of the PPAs. Niagara Mohawk would
pay only for delivered output from the units. See Part II, Item 8. Financial
Statements and Supplementary Data - Note 3. - Nuclear Operations and Note
8. - Commitments and Contingencies - Long-Term Contracts for the Purchase of
Electric Power, for a further discussion of the agreements.

NEW YORK POWER AUTHORITY
- ------------------------
Niagara Mohawk presently has contracts to purchase electricity from a number
of generation facilities owned by the NYPA. In 1999, these purchases
amounted to 7,908,000 MWh, or about 21 percent of Niagara Mohawk's total
power supply requirements. A large portion of this supply is resold to
Niagara Mohawk's "Expansion and Replacement" customers in western New York.
Niagara Mohawk credits to its residential customers, pursuant to the terms
of the agreements with NYPA, a portion of the low cost power purchased from
NYPA hydropower sources. Refer to Part II, Item 8. Financial Statements and
Supplementary Data - Note 8. - Commitments and Contingencies - Long-Term
Contracts for the Purchase of Electric Power, for a table that summarizes the
NYPA generation source, amounts of power, and the contract expiration dates
for NYPA electricity which Niagara Mohawk was entitled to purchase as of
January 1, 2000.

OTHER PURCHASED POWER
- ---------------------
Power purchased in 1999 from sources other than those noted above (other
utilities, NYPP, NYISO), amounted to 4,398,000 MWh, representing
approximately 12% of Niagara Mohawk's total power supply requirements.
Purchases from other utilities have and will continue to decrease in the
future, however, purchases made through the NYISO at market prices will
increase.

Opinac's wholly owned subsidiary, Niagara Mohawk Energy, Inc. ("Niagara Mohawk
Energy"), purchases its electricity for resale within and outside New York
State, through short-term (forward contracts) or spot market purchases.

FUEL FOR ELECTRIC GENERATION
----------------------------

During 1999, Niagara Mohawk completed the sale of its coal-fired generation
plants and its oil and gas-fired generation plant at Oswego. Niagara Mohawk
announced during 1999 an agreement to sell its Albany oil and gas-fired
generation plant. Niagara Mohawk has also entered into an agreement to sell its
interest in the Roseton plant by no later than January 1, 2003. Niagara Mohawk
is attempting to sell its interest in nuclear generation assets. The nuclear
sale is contingent upon regulatory approval.

The PowerChoice agreement eliminated Niagara Mohawk's fuel adjustment clause,
which in the past has provided for partial pass-through to customers of fuel and
purchased power cost fluctuations from amounts forecast. See Part II, Item 7.
Management's Discussion and Analysis of Financial Condition and Results of
Operations - PowerChoice and the Restructuring of the Regulated Electric Utility
Business, for a further discussion of the completed and pending sales of Niagara
Mohawk's generation assets.

NATURAL GAS. The Albany Steam Station has the capability to use natural gas, as
well as residual oil, as a fuel for electric generation. This dual-fuel
capability permits the use of the lower cost fuel depending on fuel market
conditions. During 1997, 1998, and 1999, natural gas was the predominant fuel
used. During 1997 and part of 1998, generation at this station had been
curtailed significantly because of the requirement to purchase IPP power and the
existence of excess capacity in the region. However, since the completion of
the MRA, there was a significant increase in the use of Albany Steam Station.
The output of the Albany Steam Station increased between 1997 and 1998 from 412
Gwh to 1,110 Gwh.

Niagara Mohawk purchased all natural gas for the Albany Steam Station from the
spot market. This gas was purchased as an interruptible supply.

Niagara Mohawk has a 25% ownership interest in Roseton Steam Station Units No. 1
and 2 (the "Roseton Units"). Both Roseton Units have dual fuel capability with
residual oil as the primary fuel and natural gas as the alternate fuel. Central
Hudson Gas and Electric Corporation ("Central Hudson"), a co-owner and the
operator of the Roseton Steam Station, has one contract for the supply of up to
approximately 100,000 Dths per day of natural gas for use at the Roseton Units.
In addition, Central Hudson purchases additional natural gas on the spot market
when economical. The natural gas supply is used primarily during off peak
months (April through October of each year), minimizing the exposure to
interruption. In 1999, approximately 1.5 million Dth (Niagara Mohawk's share)
of gas were used at the Roseton Units.

The annual average cost of natural gas burned by Niagara Mohawk, including the
Roseton Steam Station, was as follows:


Cost 1999* 1998 1997
- ----------------------------------------------
per million BTU $3.04 $2.35 $2.50
per Dth 3.04 2.35 2.50

* - Includes natural gas burned at the Oswego plant through October 22, 1999

RESIDUAL OIL. Fuel sulfur content standards instituted by New York State
require 1.5% sulfur content fuel oil to be burned at the Albany Steam Station.
All oil requirements were met on the spot market. At December 31, 1999, there
were approximately 236,000 barrels of oil, or a 45-day supply, at the Albany
Steam Station, based on recent burn projections. The price of 1.5% sulfur
residual oil for Albany at December 31, 1999 was $22.00 per barrel. The fuel
oil prices quoted include the $2.75 per barrel Petroleum Business Tax imposed
by New York State.

Central Hudson has arranged for the supply of residual oil for the Roseton
Units. All oil requirements are met on the spot market.

The annual average cost of residual oil burned by Niagara Mohawk, including
the Roseton Steam Station was as follows:

Cost 1999* 1998 1997
- -----------------------------------------------

NUCLEAR. The supply of fuel for Niagara Mohawk's Nine Mile Point nuclear
generation plants involves: (1) the procurement of uranium concentrates, (2)
the conversion of uranium concentrates to uranium hexafluoride, (3) the
enrichment of the uranium hexafluoride, (4) the fabrication of fuel assemblies
and (5) the disposal of spent fuel and radioactive wastes.

Agreements for nuclear fuel materials and services for Unit 1 and Unit 2 (in
which Niagara Mohawk has a 41% interest) have been made through the following
years:

Unit No. 1 Unit No. 2
----------------------
Uranium Concentrates 2002 2002
Conversion 2002 2002
Enrichment 2003 2003
Fabrication 2007 2006

Arrangements have been made for procuring a portion of the uranium, conversion
and enrichment requirements through the years listed above, leaving the
remaining portion of the requirements uncommitted. Enrichment services are
under contract with the U.S. Enrichment Corporation for up to 100% of the
requirements through the year 2003. Up to approximately 80% and 90% of the
uranium and conversion requirements are under contract through the year 2003
for Unit 1 and Unit 2, respectively. The uncommitted requirements for nuclear
fuel materials and services are expected to be obtained through long-term
contracts or secondary market purchases. If the sale of Niagara Mohawk's two
nuclear plants occurs, Niagara Mohawk would not incur any liability for future
commitments under these nuclear fuel contracts upon the sale of its interest in
the two plants.

The cost of fuel utilized at Unit 1 and Unit 2 was as follows:

Cost per million BTU 1999 1998 1997
- -------------------------------------------------------
Unit 1 $0.52 $0.51 $0.54
Unit 2 0.48 0.45 0.49

For a discussion of Niagara Mohawk's treatment of its nuclear assets under
PowerChoice, its nuclear fuel disposal costs and the disposal of nuclear wastes,
the recovery of nuclear fuel costs through rates and for further information
concerning costs relating to decommissioning of the nuclear generation plants,
see Item 8. Financial Statements and Supplementary Data - Note 1. - Summary of
Significant Accounting Policies - Depreciation, Amortization and Nuclear
Generation Plant Decommissioning Costs and Note 3. - Nuclear Operations.

ELECTRIC DELIVERY PLANNING
--------------------------

See Part II. Item 7. Management's Discussion and Analysis of Financial Condition
and Results of Operations - PowerChoice and the Restructuring of the Regulated
Electric Utility Business - FERC Order 888 - Open Access, as to how Niagara
Mohawk's transmission system will be managed under the NYISO and FERC Order 2000
regarding a December 1999 FERC proposal to create a regional transmission
organization.

As of January 1, 2000, Niagara Mohawk had approximately 128,000 miles of
transmission and distribution lines for electric delivery. Evaluation of these
facilities relative to NYISO, Northeast Power Coordinating Council, and North
American Electric Reliability Organization, planning criteria and anticipated
Niagara Mohawk internal and external demands is an ongoing process intended to
maintain the reliability of electric service while minimizing the capital
requirements for expansion of these facilities. Niagara Mohawk continually
reviews the adequacy of its electric delivery facilities and establishes capital
requirements to support new load growth.

NUCLEAR OPERATIONS
------------------

The scheduled refueling and maintenance outage at Unit 2 began on March 3,
2000 and is currently estimated to last approximately six weeks.

See Part II, Item 7. Management's Discussion and Analysis of Financial
Condition and Results of Operations - Other Federal and State Regulatory
Initiatives - NRC and Nuclear Operating Matters and PSC Staff's Tentative
Conclusions on the Future of Nuclear Generation and Part II, Item 8.
Financial Statements and Supplementary Data - Note 2. - Rate and Regulatory
Issues and Contingencies and Note 3. - Nuclear Operations.

GAS SUPPLY
----------

The majority of Niagara Mohawk's gas sales are for residential and commercial
space and water heating. Consequently, the demand for natural gas by Niagara
Mohawk's customers is seasonal and influenced by weather factors. Niagara
Mohawk purchases its natural gas for sale to its customers under firm and spot
contracts, which is transported under both firm and interruptible transportation
contracts. During 1999, about 82% of Niagara Mohawk's natural gas supply was
purchased under firm contracts and 18% was purchased under spot contracts. The
spot contracts are generally for commitments less than 30 days. See Part II.
Item 8. Financial Statements and Supplementary Data - Note 8. - Commitments and
Contingencies - Gas Supply, Storage and Pipeline Commitments. In addition,
Niagara Mohawk has a commitment with CNG to provide gas storage capability until
March 2002. See Part II, Item 7. Management's Discussion and Analysis of
Financial Condition and Results of Operation - Other Federal and State
Regulatory Initiatives - Future of the Natural Gas Industry, for a discussion of
the PSC's 1998 proposal, that natural gas utilities exit the business of
purchasing natural gas for customers.

Niagara Mohawk Energy purchases its gas for resale both within and outside New
York State, through short term (futures contracts) and spot market purchases.

GAS DELIVERY
------------

Niagara Mohawk sells, distributes and transports natural gas to a geographic
territory that generally extends from Syracuse to Albany. The northern reaches
of the system extend to Watertown and Glens Falls. Not all of Niagara Mohawk's
distribution areas are physically interconnected with one another by its own
facilities. Presently, 9 separate distribution areas are connected directly
with CNG, an interstate natural gas pipeline regulated by the FERC, via 17
delivery stations. Niagara Mohawk also has two direct connections with Iroquois
Gas Transmission and one with Empire State Pipeline.

FINANCIAL INFORMATION ABOUT SEGMENTS
------------------------------------

See Part II, Item 7. Management's Discussion and Analysis of Financial Condition
and Results of Operations and Item 8. Financial Statements and Supplementary
Data - Note 11. - Segment Information.

ENVIRONMENTAL MATTERS
---------------------

GENERAL. Niagara Mohawk's operations and facilities are subject to numerous
federal, state and local laws and regulations relating to the environment
including, among other things, requirements concerning air emissions, water
discharges, site remediation, hazardous materials handling, waste disposal and
employee health and safety. While Niagara Mohawk devotes considerable resources
to environmental compliance and promoting employee health and safety, the impact
of future environmental health and safety laws and regulations on Niagara Mohawk
cannot be predicted with certainty.

In compliance with environmental statutes and consistent with its strategic
philosophy, Niagara Mohawk performs environmental investigations and analyses
and installs, as required, pollution control equipment, including, among other
things, effluent monitoring instrumentation and materials storage/handling
facilities designed to prevent or minimize releases of potentially harmful
substances. Expenditures for environmental matters for 1999 totaled
approximately $31.9 million, of which approximately $8.6 million was capitalized
as pollution control or plant environmental surveillance equipment and
approximately $23.3 million was charged to operating expense for remediation,
operation of environmental monitoring and waste disposal programs. Expenditures
for 2000 are estimated to total $33.0 million, of which $3.1 million is expected
to be capitalized and $29.9 million charged to operating expense. Anticipated
expenditures for 2001 are estimated to total $34.1 million, of which $2.1
million is expected to be capitalized and $32.0 million charged to operating
expense. The expenditures for 2000 and 2001 include the estimated costs for
Niagara Mohawk's expected proportionate share of the costs for site
investigation and remediation of waste sites discussed under "Solid/Hazardous
Waste" below, but exclude costs for the fossil and hydro generation plants.
Costs for site investigation and remediation are included in operating expense
to the extent actual costs exceed the amount provided for in rates, in which
case, the excess costs are deferred for future recovery through cost-of-service
based rates.

Niagara Mohawk believes it is probable that costs associated with environmental
compliance will continue to be recovered through the ratemaking process. For a
discussion of the circumstances regarding Niagara Mohawk's continued ability to
recover these types of expenditures in rates, see Part II, Item 8. Financial
Statements and Supplementary Data - Note 2. - Rates and Regulatory Issues and
Contingencies.

ISO 14001. During 1997, Niagara Mohawk had its fossil and nuclear generation
plants (Oswego, Albany, Huntley and Dunkirk Steam Stations and Nine Mile Point)
certified to the ISO 14001 environmental management system standard. The
registration audits of these facilities were conducted by Advanced Waste
Management Systems. Niagara Mohawk's investment recovery facility was
registered to ISO 14001 in October 1999. Niagara Mohawk's position has been,
and continues to be, that an effective environmental management system is
necessary to prudently manage environmental issues and minimize environmental
liabilities.

Once Niagara Mohawk completes the sales of its remaining generation assets,
Niagara Mohawk will no longer be responsible for meeting the related
environmental requirements. The following discussion of air, water and solid
waste matters presents Niagara Mohawk's plans for addressing environmental
requirements in the event Niagara Mohawk were to retain ownership of its
remaining generation assets.

AIR. Niagara Mohawk is required to comply with applicable federal and state air
quality requirements pertaining to emissions into the atmosphere from its
fossil-fired generation stations and other air emission sources.

Phase II requirements associated with Title IV of the Clean Air Act (targeted
for the year 2000 and beyond) will require owners of fossil plants to further
reduce their SO2. Possible options for Phase II SO2 compliance, beyond those
considered for Phase I compliance, include fuel switching, installation of flue
gas desulfurization or clean coal technologies, repowering and the use of
emission allowances created under the Clean Air Act. Appropriate deployment of
these options will be determined by the new owners of the Albany plant.

In September 1994, the states comprising the Northeast Ozone Transport
Commission (New York State included) signed a Memorandum of Understanding that
called for each member state to develop regulations for two additional phases of
NOx reduction beyond RACT (referred to as Phase II and Phase III NOx
reductions). In Phase II, air emission sources located in upstate New York
(which included all of Niagara Mohawk's air emission sources) had to reduce NOx
emissions by May 1999 by 55% relative to 1990 levels. In Phase III, these air
emission sources will have to reduce NOx emissions in May 2003 by 75% relative
to 1990 levels. The Memorandum of Understanding provides that the specified
reductions in Phase III may be modified if evidence shows that alternative NOx
reductions, together with other emission reductions, will satisfy the air
quality standard across the region. The DEC has finalized regulations governing
the Phase II NOx reduction program in New York State, which was implemented
beginning May 1, 1999. The DEC has also issued proposed Phase III NOx reduction
regulations. Since Phase III NOx reductions will not be required until the year
2003, this should not have an impact on Niagara Mohawk as a result of the
pending sale of the Albany Steam Station.

Niagara Mohawk has spent less than $1.0 million in capital expenditures during
1997 through 1999 to comply with the Clean Air Act. For a discussion of Niagara
Mohawk's negotiations with the DEC on a Consent Decree addressing past opacity
excursions and future opacity compliance issues, see Item 3. Legal Proceedings.

WATER. Niagara Mohawk is required to comply with applicable federal and state
water quality requirements, including the Clean Water Act, in connection with
the discharge of condenser cooling water and other wastewaters from its
steam-electric generation stations and other facilities. A wastewater discharge
permit was issued by DEC for the Albany Steam Station. This permit must be
renewed every five years. Conditions of the permits typically require that
studies be performed to determine the effects of station operation on the
aquatic environment in the station vicinity and to evaluate various technologies
for mitigating losses of aquatic life. This should not have an impact on
Niagara Mohawk due to the pending sale of Albany plant.

LOW LEVEL RADIOACTIVE WASTE. See Part II, Item 8. Financial Statements and
Supplementary Data - Note 3. - Nuclear Operations - Low Level Radioactive Waste.

SOLID/HAZARDOUS WASTE. The public utility industry typically utilizes and/or
generates in its operations a broad range of hazardous and potentially hazardous
wastes and by-products. Niagara Mohawk believes it is handling identified
wastes and by-products in a manner consistent with federal, state and local
requirements and has implemented an environmental audit program to identify any
potential areas of concern and aid compliance with such requirements.
Niagara Mohawk is also currently conducting a program to investigate and
remediate, as necessary, to meet current environmental standards, certain
properties associated with former gas manufacturing and other properties which
Niagara Mohawk has learned may be contaminated with industrial waste, as well as
investigating identified industrial waste sites as to which it may be determined
that Niagara Mohawk has contributed. Niagara Mohawk has also been advised that
various federal, state or local agencies believe certain properties require
investigation and has prioritized the sites based on available information in
order to enhance the management of investigation and remediation, if necessary.
See Part II, Item 8. Financial Statements and Supplementary Data - Note 8. -
Commitments and Contingencies - Environmental Contingencies for a discussion of
the sites which are Niagara Mohawk owned.

With respect to sites not owned by Niagara Mohawk, but for which it has been or
may be associated as a PRP, Niagara Mohawk has recorded a liability of $90
million, representing its current estimate of its share of the total cost to
investigate and remediate these sites. Total costs to investigate and remediate
all non-owned sites is estimated to be approximately $245 million, but it is
unlikely that Niagara Mohawk will be required to assume 100% of the
responsibility for these sites. Niagara Mohawk has denied any responsibility
for certain of these PRP sites and is contesting liability accordingly. Twelve
of the PRP sites are included on the National Priorities List ("NPL"). Niagara
Mohawk estimates that its share of the liability for these 12 sites is not
material and has included the amount in the determination of the amounts
accrued.

Estimates of Niagara Mohawk's potential liability for sites not owned by Niagara
Mohawk, but for which it has been identified as an alleged PRP, have been
derived by estimating the total cost of site cleanup and then applying Niagara
Mohawk's contribution factor to that estimate where appropriate. Estimates of
the total cleanup costs are determined by using all available information from
investigations conducted by Niagara Mohawk and other parties, negotiations with
other PRPs and, where no other basis is available at the time of estimate, the
EPA figure for average cost to remediate a site listed on the NPL as disclosed
in the Federal Register of June 23, 1993 (58 Fed. Reg. 119). A contribution
factor is calculated when there is a reasonable basis for it, that uses either a
pro rata share based upon the total number of PRPs named or otherwise identified
or the percentage agreed upon with other PRPs through steering committee
negotiations or by other means. In some instances, Niagara Mohawk has been
unable to determine a contribution factor and has included in the amount accrued
the total estimated costs to remediate the sites. Actual Niagara Mohawk
expenditures for these sites are dependent upon the total cost of investigation
and remediation and the ultimate determination of Niagara Mohawk's share of
responsibility for such costs as well as the financial viability of other PRPs
since cleanup obligations are joint and several.

In May 1997, the DEC executed an Order of Consent (the "1997 Order") which
serves to keep the annual cash requirement for certain site investigation and
remediation ("SIR") level (at approximately $15 million per year), and which
provides for an annual site prioritization mechanism. Niagara Mohawk has a
carryover from prior years underspending of approximately $12.6 million, of
which it anticipates reducing by $5 million in 2000. As executed, the 1997
Order expands the scope of the original 1992 Order, which covered 21 former MGP
sites, to encompass all additional sites with which Niagara Mohawk has been
associated. The agreement is supported by the decision analysis approach, which
Niagara Mohawk and the DEC will continue to revise on an annual basis to address
SIR progress and site priorities relative to establishing the annual cost cap,
as well as determining Niagara Mohawk's liability for these sites. The Saratoga
Springs and Harbor Point MGP sites are being investigated and remediated
pursuant to separate regulatory Consent Orders with the EPA and the DEC,
respectively. However, the annual costs associated with the remediation of
these sites are included in the cash requirements under the amended 1997 Order.

PowerChoice and Niagara Mohawk's gas settlement provide for the recovery of SIR
costs during the settlement periods. Niagara Mohawk believes future costs,
beyond the settlement periods, will continue to be recovered in rates. Based
upon this assessment, a regulatory asset has been recorded in the amount of $240
million, representing the future recovery of remediation obligations accrued to
date. As a result, Niagara Mohawk does not believe SIR costs will have a
material adverse effect on its results of operations or financial condition.

- - Rate and Regulatory Issues and Contingencies.

RESEARCH AND DEVELOPMENT
------------------------

Niagara Mohawk maintains a research and development ("R&D") program aimed at
improving the delivery and use of energy products and finding practical
applications for new and existing technologies in the energy business. These
efforts include:

- - improving efficiency
- - minimizing environmental impacts
- - improving facility availability
- - minimizing maintenance costs
- - promoting economic development
- - improving the quality of life for its customers with new electric and gas
technologies

R&D expenditures in 1997 through 1999 were not material to Holdings or Niagara
Mohawk's results of operations or financial condition.

CONSTRUCTION PROGRAM
--------------------

See Part II, Item 7. Management's Discussion and Analysis of Financial Condition
and Results of Operations - Financial Position, Liquidity and Capital Resources
- - Construction and Other Capital Requirements and Part II, Item 8. Financial
Statements and Supplementary Data - Note 8. - Commitments and Contingencies -
Construction Program.

INSURANCE
---------

As of January 31, 2000, Holdings' directors and officers liability insurance was
renewed. This coverage includes nuclear operations and insures the directors
and officers against obligations incurred as a result of their indemnification
by Holdings. The coverage also insures the directors and officers against
liabilities for which they may not be indemnified by Holdings, except for a
dishonest act or breach of trust. In addition, the policy covers all of
Holdings subsidiaries. For a discussion of nuclear insurance, see Part II, Item
8. Financial Statements and Supplementary Data - Note 3. - Nuclear Operations -
Nuclear Liability Insurance and - Nuclear Property Insurance.

EMPLOYEE RELATIONS
------------------

Niagara Mohawk's work force at December 31, 1999 numbered approximately 7,400,
of whom approximately 68% were union members. It is estimated that
approximately 78% of Niagara Mohawk's total labor cost is applicable to
operation and maintenance and approximately 22% is applicable to construction
and other accounts.

All of Niagara Mohawk's non-supervisory production and clerical workers subject
to collective bargaining are represented by the International Brotherhood of
Electrical Workers ("IBEW"). In April 1996, Niagara Mohawk and the IBEW agreed
on a five-year, three-month labor agreement, which provides for wage increases
of approximately 2% to 3% in each of the subsequent four years.

Niagara Mohawk's work force decreased during 1999 as a result of the sale of its
fossil and hydro generation assets. In addition, Niagara Mohawk's work force
should also decrease during 2000 as a result of the closing on the sale of the
Albany plant and could decrease by approximately 1,300 if the nuclear generation
plants are sold.

Opinac's wholly owned subsidiary, Niagara Mohawk Energy, has approximately 100
employees.

ITEM 2. PROPERTIES

ELECTRIC DELIVERY
-----------------

NIAGARA MOHAWK: During 1999, Niagara Mohawk completed the sale of its
coal-fired generation plants, its hydro electric plants, its oil and gas-fired
plant in Oswego, and its interest in Beebee Island and Feeder Dam hydro plants
and their output. As of December 31, 1999, Niagara Mohawk owned and operated
one fossil fuel steam plant, had a 25% interest in the Roseton Steam Station
and its output, and owned and operated two nuclear plants. During 1999,
Niagara Mohawk announced plans to sell these remaining generation assets.
The sale of the nuclear generation assets is uncertain, because it is subject
to significant regulatory approval. See Part II, Item 7. Management's
Discussion and Analysis of Financial Condition and Results of Operations -
PowerChoice and the Restructuring of the Regulated Electric Utility Business,
for a discussion of the sales and announced sales of Niagara Mohawk's generation
assets.

The following is a list of Niagara Mohawk's major remaining generation stations
at December 31, 1999:




Niagara Mohawk's
Share of
Nominal Net
Percent Capability

Nine Mile Point (Unit 1) Lake Ontario 100% Nuclear 613
Nine Mile Point (Unit 2) Lake Ontario 41% Nuclear 469



As of December 31, 1999, Niagara Mohawk's electric transmission and distribution
systems were composed of:

- - 952 substations with a rated transformer capacity of approximately
28,500,000 kilovoltamperes
- - approximately 8,000 circuit miles of overhead transmission lines
- - approximately 1,100 cable miles of underground transmission lines
- - approximately 113,100 conductor miles of overhead distribution lines
- - about 5,800 cable miles of underground distribution cables

Only a part of Niagara Mohawk's transmission and distribution lines are
located on property owned by Niagara Mohawk.

There is seasonal variation in electric customer load. In 1998 and 1999,
Niagara Mohawk's maximum hourly demand occurred in the summer. Prior to 1998,
Niagara Mohawk's maximum hourly demand occurred in the winter. The maximum
simultaneous hourly demand (excluding economy and emergency sales to other
utilities) on the electric system of Niagara Mohawk for the 12 months ended
December 31, 1999 occurred on July 16, 1999 and was 6,098 KWh.

OPINAC: Holdings' unregulated subsidiary, Opinac, through its subsidiary Opinac
Energy Corporation, owns a 50 percent interest in Canadian Niagara Power Company
Limited ("CNP") (owner and operator of the 76.8 MW Rankine hydroelectric plant)
which distributes electric power within the province of Ontario.

The electric system of Niagara Mohawk and CNP is directly interconnected with
other electric utility systems in Ontario, Quebec, New York, Massachusetts,
Vermont and Pennsylvania, and indirectly interconnected with most of the
electric utility systems through the Eastern Interconnection of the United
States.

GAS DELIVERY
------------

Niagara Mohawk distributes gas purchased from suppliers and transports gas owned
by others. As of December 31, 1999, Niagara Mohawk's natural gas delivery
system was comprised of approximately 12,000 miles of pipelines and mains. Only
a part of these natural gas pipelines and mains are located on property owned by
Niagara Mohawk.

SUBSIDIARIES
------------

Holdings has two subsidiaries as follows:

(1) Niagara Mohawk, the regulated subsidiary which has the following
subsidiaries:

(a) NM Uranium, Inc. - has an interest in a uranium mining operation in
Live Oak County, Texas, which is now in the process of reclamation and
restoration.
(b) NM Properties, Inc. - engages in real estate development and
divestiture of property formerly owned by Niagara Mohawk.
(c) NM Receivables - facilitates the sale of an undivided interest in a
designated pool of customer receivables, including accrued unbilled
revenues. NM Receivables, LLC is owned by Niagara Mohawk (over 99.99%)
and by NM Receivables Corp. II, which is a wholly owned subsidiary of
Niagara Mohawk.
(2) Opinac, the unregulated subsidiary which owns:

(a) Opinac Energy Corporation - a Canadian corporation which has portfolio
investments and owns a 50 percent interest in CNP. CNP is an electric
company, which has operations in the province of Ontario, Canada. CNP
generates electricity at its Rankine hydro plant for the wholesale
market and for its distribution system in Fort Erie, Ontario.
(b) Niagara Mohawk Energy, Inc. - was incorporated in the state of Delaware
and is an unregulated company that offers energy-related services.
(c) An investment in a development stage telecommunications company
(Telergy, Inc.).
(d) An investment in a research and development company (EVonyx, Inc.) that
has developed and intends to commercialize, new fuel cell and battery
technology.

NATIVE AMERICAN MATTERS
-----------------------

Niagara Mohawk owns and operates approximately 50 miles of electric transmission
lines, over approximately 350 acres, crossing the Seneca Nation, Cattaraugus and
Allegheny Reservations, which range from 230 kilovolts to 34.5 kilovolts. In
1991, the Seneca Nation ("Nation") opened discussions alleging the invalidity of
the right-of-way agreements for these transmission lines. While discussions
between the Nation and Niagara Mohawk were suspended in mid-1992, in 1997, the
Nation asked Niagara Mohawk to reopen the discussions. On September 30, 1998,
the Nation filed, in the U.S. District Court for the Western District of New
York, a civil action to eject Niagara Mohawk from the Nation's land and is also
seeking financial relief from Niagara Mohawk. The litigation has been suspended
since October 1999, as a result of Niagara Mohawk and the Nation reaching a
tentative settlement. Niagara Mohawk and the Nation are currently negotiating
the terms and conditions of a settlement agreement and a new right-of-way
agreement for the electric transmission lines on the Seneca Reservations. The
terms of the tentative settlement agreement are not material to Niagara Mohawk's
results of operation or financial position. Niagara Mohawk is unable to predict
whether this tentative settlement agreement will be finalized, whether the terms
of such an agreement will materially change, or the outcome of litigation, if a
settlement is not finalized.

Niagara Mohawk has also held discussions with other Native American nations and
was involved in legal proceedings regarding the PSC's jurisdiction over their
territories, Niagara Mohawk's right to provide service to individuals located
within these territories, the validity of franchise agreements within their
territories, and Niagara Mohawk's right to collect stranded costs. The
potential outcome of these discussions could lead to, but is not limited to,
more formalized litigation proceedings. Niagara Mohawk intends to continue
these discussions and defend its position, but is unable to predict the timing
or outcome of these matters.

MORTGAGE LIENS
--------------

Substantially all of Niagara Mohawk's operating properties are subject to a
mortgage lien securing its mortgage debt.



ITEM 3. LEGAL PROCEEDINGS

For a detailed discussion of additional legal proceedings, see Part II, Item 8.
Financial Statements and Supplementary Data - Note 8. - Commitments and
Contingencies - Environmental Contingencies. See also Item 1. Business -
Environmental Matters - Solid/Hazardous Waste, Item 2. Properties - Native
American Matters, and Part II, Item 7. Management's Discussion and Analysis of
Financial Condition and Results of Operations - PowerChoice and the
Restructuring of the Regulated Electric Utility Business. Holdings and Niagara
Mohawk are unable to predict the ultimate disposition of the matters referred to
below. In addition, consistent with PowerChoice and its gas settlement
agreement, Niagara Mohawk believes that it is probable that it will continue to
recover these types of expenditures in cost-of-service based rates. See also
Part II, Item 8. Financial Statements and Supplementary Data - Note 2. - Rate
and Regulatory Issues and Contingencies.

1. On June 22, 1993, Niagara Mohawk and 20 other industrial entities, as
well as the owner/operator of the Pfohl Brothers Landfill near Buffalo, New
York, were sued in New York State Supreme Court, Erie County, by a group of
residents living in the area surrounding the landfill. The plaintiffs seek
compensation for alleged economic loss and property damage claimed to have
resulted from exposure to contamination associated with the landfill. In
addition, since January 18, 1995, Niagara Mohawk has been named as a
defendant or third party defendant in a series of toxic tort actions filed
in federal or state courts in the Buffalo area. These actions allege
exposure on the part of plaintiffs or plaintiffs' decedents to toxic
chemicals emanated from the landfill, resulting in the alleged causation of
property damage and/or physical injury. The plaintiffs seek compensatory
and punitive damages so far totaling approximately $60 million. Niagara
Mohawk has filed answers responding to the claims put forth in these suits,
denying liability as to any of the claimed conditions or damages and intends
to continue to vigorously defend against each claim.

Niagara Mohawk is unable to predict at this time the probable outcome of
these proceedings, which at present remain in the discovery stage. Niagara
Mohawk, through participation in the Pfohl Brothers Landfill Site Committee,
is assisting in the design and implementation of a remedial program which is
expected to be memorialized in an administrative consent order to be
executed during the second quarter of 2000. In the context of remedial cost
allocation procedures conducted on behalf of the Committee, it has been
determined that Niagara Mohawk's contribution of industrial wastes to the
landfill was minor. Further, it is Niagara Mohawk's position that any
materials attributable to Niagara Mohawk, which may have been disposed of at
the landfill are not causally related to any physical condition alleged by
plaintiffs in the various lawsuits associated with the landfill. Niagara
Mohawk does not believe that the outcome of these proceedings will have a
material adverse effect on its results of operations or financial condition.

2. On February 4, 1994, Niagara Mohawk notified NorCon Partners, LP ("NorCon")
of its demand for adequate assurance that NorCon would perform all of
their future repayment obligations as required by agreement.

On March 7, 1994, NorCon filed a complaint in the U.S. District Court
seeking to enjoin Niagara Mohawk from terminating a PPA between the parties
and seeking a declaratory judgment that Niagara Mohawk has no right to
demand additional security or other assurances of NorCon's future
performance under the PPA. On March 26, 1997, the U.S. Court of Appeals
for the Second Circuit ordered that the question of whether there exists
under New York commercial law the right to demand firm security on an
electric contract should be certified to the New York Court of Appeals,
the highest New York court, for an advisory ruling. The Second Circuit
order effectively stayed the U.S. District Court's order against Niagara
Mohawk, pending final disposition by the New York Court of Appeals. A
motion to stay further proceedings was made since this contract was included
in the MRA.

NorCon subsequently dropped out of the MRA, and arguments were held on
October 22, 1998 in the New York Court of Appeals at the request of Niagara
Mohawk. A settlement agreement was reached on October 14, 1999 between
Niagara Mohawk and NorCon to terminate the PPA, which also settles Niagara
Mohawk's original demand for adequate assurance for future performance.
The settlement agreement also included payments to General Electric Capital
Corporation and Louis Dreyfus Natural Gas Corporation as a result of the
termination of the PPA. This settlement agreement was finalized and
implemented with the execution of comprehensive settlement documents and
payment of settlement funds on December 2, 1999. The settlement payment by
Niagara Mohawk totaled $125 million, which has been deferred. Niagara
Mohawk has petitioned the PSC to amortize this deferral over an eight-year
period.

3. In November 1993, Fourth Branch Associates Mechanicville ("Fourth
Branch") filed an action against Niagara Mohawk and several of its officers
and employees in the New York State Supreme Court, seeking compensatory
damages of $50 million, punitive damages of $100 million, and injunctive
and other related relief. The lawsuit grows out of Niagara Mohawk's
termination of a contract for Fourth Branch to operate and maintain a
hydroelectric plant Niagara Mohawk owned in the Town of Halfmoon, New York.
Fourth Branch's complaint also alleges claims based on the inability of
Fourth Branch and Niagara Mohawk to agree on terms for the purchase of
power from a new facility that Fourth Branch hoped to construct at the
Mechanicville site. In January 1994, Niagara Mohawk filed a motion to
dismiss Fourth Branch's complaint. By order dated November 7, 1995, the
Court granted Niagara Mohawk's motion to dismiss the complaint in its
entirety. Fourth Branch filed an appeal from the Court's order. On
January 30, 1997, the Appellate Division modified the November 7, 1995
court decision by reversing the dismissal of the fourth and fifth causes
of action set forth in Fourth Branch's complaint. Discovery proceedings
are in progress with respect to the two causes of action.

Niagara Mohawk and Fourth Branch had also entered into negotiations under
a FERC mediation process. As a result of these negotiations, Niagara Mohawk
had proposed to sell the hydroelectric plant to Fourth Branch for an amount
which would not be material. In addition, the proposal included a provision
that would require the discontinuance of all litigation between the parties.

Attempts to implement this proposal were unsuccessful, and Niagara Mohawk
informed FERC that its participation in the mediation efforts was concluded.
On January 14, 1997, the FERC Administrative Law Judge issued a report to
FERC recommending that the mediation proceeding be terminated, leaving
outstanding a Fourth Branch complaint to FERC that alleges anti-competitive
conduct by Niagara Mohawk. Niagara Mohawk has made a motion to dismiss
Fourth Branch's antitrust complaint before the FERC, which motion was
opposed by Fourth Branch.

During July 1998, Fourth Branch commenced a condemnation proceeding in
Federal District Court to obtain title to the project property and also has
made a unilateral offer of settlement before FERC. Niagara Mohawk served an
answer with various affirmative defenses. On July 30, 1998, Fourth Branch
moved for Summary Judgment. Niagara Mohawk opposed Fourth Branch's motion
and cross-moved for summary judgment in favor of Niagara Mohawk. The Court
granted Niagara Mohawk's motion for summary judgment on September 1, 1999.

On September 10, 1999, Fourth Branch filed an amended unilateral offer of
settlement with FERC. On September 30, 1999, Niagara Mohawk filed its
response and objection to the amended offer of settlement. On November 23,
1999, FERC issued a comprehensive order rejecting Fourth Branch's unilateral
offer of settlement, dismissing Fourth Branch's complaint of
anti-competitive conduct against Niagara Mohawk and determining that there
has been an implied surrender by Fourth Branch and Niagara Mohawk of the
FERC license for the Mechanicville Project. On December 23, 1999, Fourth
Branch filed a petition for rehearing of the Commission's decision.

Niagara Mohawk is unable to predict the ultimate disposition of the lawsuit
and FERC case referred to above. However, Niagara Mohawk believes it has
meritorious defenses and intends to defend them vigorously. No provision
for liability, if any, that may result from this lawsuit has been made in
Niagara Mohawk's financial statements.

4. The DEC, in response to an EPA audit of DEC enforcement policies, which
found enforcement of air regulation violations to be insufficient, began an
initiative to address this issue in 1997. As a result, the DEC began to
pursue consent orders from all New York utilities for past opacity
variances. The consent order also includes various opacity reduction
measures and stipulated penalties for future excursions after execution of
a consent order. Niagara Mohawk is in the process of finalizing a mutually
agreeable consent order. Niagara Mohawk believes that the penalties for
past opacity variances will be immaterial to its results of operations.
The stipulated penalties for future excursions will be negotiated between
the new owners of the fossil generation plants and the DEC.

5. In July 1998, the Public Utility Law Project of New York, Inc. (PULP) and
others sought a declaratory judgment, declaring Niagara Mohawk's PowerChoice
agreement unlawful, null and void and injunctive relief in the Supreme Court
of the state of New York, Albany County against the PSC and Niagara Mohawk
to enjoin the defendants to halt all their actions and expenditures to
implement the rules for the provision of retail energy services contained
in the PowerChoice agreement. The PSC and Niagara Mohawk filed motions
seeking to dismiss this action. By a decision dated March 2, 2000, Albany
County Supreme Court granted the motions to dismiss PULP's action. PULP
will have 30 days following service of the decision and order with notice
of entry in which to file a notice of appeal. Niagara Mohawk is unable to
predict the outcome of this matter.

PART II

ITEM 5. MARKET FOR THE REGISTRANTS' COMMON EQUITY AND RELATED STOCKHOLDER
MATTERS

HOLDING COMPANY FORMATION. On March 18, 1999, Niagara Mohawk Power Corporation
("Niagara Mohawk") was reorganized into a holding company structure in
accordance with its Agreement and Plan of Exchange between Niagara Mohawk and
Niagara Mohawk Holdings, Inc. ("Holdings"). Niagara Mohawk's outstanding
common stock was exchanged on a share-for-share basis for Holdings' common
stock. Niagara Mohawk's preferred stock and debt were not exchanged as part
of the share exchange and continue as shares and debt of Niagara Mohawk.

HOLDINGS COMMON STOCK. Holdings is authorized to issue 300 million shares of
common stock. Holdings' common stock (par value $0.01) and certain of Niagara
Mohawk's preferred series are listed on the New York Stock Exchange ("NYSE").
Holdings' common stock is also traded on the Boston, Cincinnati, Midwest,
Pacific and Philadelphia stock exchanges. Holdings' common stock options are
traded on the American Stock Exchange. The ticker symbol is "NMK."

Holdings' common stock has been traded on the NYSE since March 19, 1999. Prior
to that date, the market prices on the table below refer to Niagara Mohawk's
common stock.

For a discussion regarding Holdings and Niagara Mohawk's common stock dividend,
see Item 7. - Management's Discussion and Analysis of Financial Condition and
Results of Operations - Financial Position, Liquidity and Capital Resources -
Common Stock Dividend below.

The holders of Holdings' common stock are entitled to one vote per share and may
not cumulate their votes for the election of Directors. Upon any dissolution,
liquidation or winding up of Holdings' business, the holders of common stock are
entitled to receive a pro rata share of all of Holdings' assets remaining and
available for distribution after the full amounts to which holders (if any) of
Holdings' preferred stock are entitled have been satisfied.

After the closing of the MRA (see Part II, Item 7. - Management's Discussion and
Analysis of Financial Condition and Results of Operations - PowerChoice and the
Restructuring of the Regulated Electric Utility Business - The MRA Agreement,
IPP Parties and their designees owned approximately 20.5 million shares of
Niagara Mohawk's common stock, representing approximately 11% of Niagara
Mohawk's voting securities. These shares were also exchanged on March 18,
1999 on a share-for-share basis for Holdings' common stock. Pursuant to the
MRA, any IPP Party that received 2% or more of the outstanding common stock
and any designee of IPP Parties that received more than 4.9% of the outstanding
common stock upon the consummation of the MRA, together with certain but not
all affiliates (collectively, "2% Shareholders"), entered into certain
shareholder agreements (the "Shareholders Agreements"). Pursuant to each
Shareholder Agreement, the 2% Shareholders agree that for five years from the
consummation of the MRA, they will not acquire more than an additional 5% of
the outstanding common stock (resulting in ownership in all cases of no more
than 9.9%) or take any actions to attempt to acquire control of Holdings,
other than certain permitted actions in response to unsolicited actions by
third parties. The 2% Shareholders generally vote their shares on a
"pass-through" basis, in the same proportion as all shares held by other
shareholders are voted, except that they may vote in their discretion (i)
for extraordinary transactions and (ii) for directors when there is a
pending proposal to acquire Holdings.

In 1999, the PSC approved Niagara Mohawk's petition to purchase up to $800
million of Holdings' common stock. Holdings and Niagara Mohawk's Board of
Directors have approved a program to repurchase 20 million shares through
December 31, 2001. See Part II, Item 8. - Financial Statements and
Supplementary Data, Note 4. - Capitalization, for a further discussion of
the shares repurchased.

As of January 1, 2000, there were approximately 53,600 holders of record of
common stock of Holdings and about 2,900 holders of record of Niagara Mohawk's
preferred stock. The chart below summarizes common stockholder ownership by
size of holding:

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



HOLDINGS PREFERRED STOCK. Holdings is authorized to issue 50 million shares of
preferred stock with a par value of $0.01. No preferred stock had been issued
as of December 31, 1999.

NIAGARA MOHAWK COMMON STOCK. Niagara Mohawk is authorized to issue 250 million
shares of common stock with a par value of $1.00. As of December 31, 1999,
Niagara Mohawk has 187,364,863 shares outstanding, which are all held by
Holdings and are not traded.

The indenture securing Niagara Mohawk's mortgage debt provides that retained
earnings shall be reserved and held unavailable for the payment of dividends on
common stock to the extent that expenditures for maintenance and repairs plus
provisions for depreciation do not exceed 2.25% of depreciable property as
defined therein. Such provisions have never resulted in a restriction of
Niagara Mohawk's retained earnings.

NIAGARA MOHAWK PREFERRED STOCK. The share exchange and the formation of the
holding company structure did not change the rights of holders of the
outstanding shares of Niagara Mohawk's preferred stock. Niagara Mohawk's
preferred stock continues to rank senior to Niagara Mohawk's common stock
(which are held by Holdings) as to dividends and as to distribution of Niagara
Mohawk's assets upon any liquidation.

Whenever dividends on Niagara Mohawk's preferred stock are in default in an
amount equivalent to four full quarterly dividends and thereafter until all
dividends thereon are paid or declared and set aside for payment, the holders
of such preferred stock can elect a majority of the Board of Directors of
Niagara Mohawk. Whenever dividends on any preference stock are in default
in an amount equivalent to six full quarterly dividends and thereafter until
all dividends thereon are paid or declared and set aside for payment, the
holders of such stock can elect two members to the Board of Directors of
Niagara Mohawk. No dividends on preferred stock are now in arrears and no
preference stock is now outstanding.

Niagara Mohawk paid preferred dividends on March 31, June 30, September 30,
and December 31. Niagara Mohawk estimates that none of the 1999 preferred
stock dividends will constitute a return of capital, and therefore, all of
such dividends are subject to federal tax as ordinary income.



ITEM 6. SELECTED CONSOLIDATED FINANCIAL DATA

The following table sets forth selected financial information of Holdings for
1999 and for Niagara Mohawk (Holdings' predecessor) for each of the five years

NIAGARA MOHAWK HOLDINGS, INC. AND SUBSIDIARY COMPANIES

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

The electric utility industry in the United States has experienced a
deregulatory climate in recent years whereby federal and state regulatory
initiatives have sought to provide separation of the vertically integrated
energy generation, transmission and distribution functions and promote
competition and lower prices. This unbundling of services has led to some
restructuring throughout the industry. Niagara Mohawk's response to these
developments was to formulate a restructuring strategy and a multi-year rate
plan which enables it to exit the generation business, reduce the amount of
its over-market purchase power obligations, recover its stranded costs and
lower prices to customers. Implementation of this restructuring strategy
commenced in 1998 with the regulatory approval of the rate plan and the
consummation of the MRA, and 1999 was a year punctuated by the further
execution of the restructuring strategy. Key events were:

- - On March 18, 1999, Niagara Mohawk was reorganized into a holding company
structure providing Holdings and its subsidiaries with financial and
regulatory flexibility to compete more effectively in an increasingly
competitive energy industry.

- - On June 11, 1999, Niagara Mohawk completed the sale transactions of its two
coal-fired generation plants; on July 29, 1999, Niagara Mohawk completed the
sale of its hydroelectric generation plants; and on October 22, 1999, Niagara
Mohawk completed the sale of its oil and gas-fired plant at Oswego. In
addition, on October 6, 1999, Niagara Mohawk announced an agreement to sell
its oil and gas-fired generation plant at Albany.

- - On June 24, 1999, Niagara Mohawk announced an agreement to sell its nuclear
generation assets to AmerGen Energy Company, LLC ("AmerGen"). However, on
December 21, 1999, Rochester Gas & Electric Corporation ("RG&E") notified
Niagara Mohawk of its intent to exercise its rights to purchase the nuclear
generation assets. The PSC Staff has informed Niagara Mohawk that they
believed that the terms of the proposed sale are not consistent with the
public interest standard in the Public Service Law, but discussions with
AmerGen and other interest parties would continue.

- - Niagara Mohawk redeemed approximately $1.1 billion in debt.

- - In the fourth quarter, Niagara Mohawk commenced a multi-year program to
repurchase shares of Holdings' common stock. The repurchases are aimed at
managing Holdings' capital structure to competitive norms within the
utility industry.

- - The PSC established a formal proceeding on the methodology to determine
exit fees.

- - Niagara Mohawk implemented a new customer service system, which continues to
experience transition issues in customer satisfaction, incremental costs and
PSC scrutiny.

POWERCHOICE AND THE RESTRUCTURING OF THE REGULATED ELECTRIC UTILITY BUSINESS
- ----------------------------------------------------------------------------

The PSC approved the PowerChoice agreement on March 20, 1998 and the rate plan
was implemented beginning September 1, 1998. The PowerChoice agreement outlined
Niagara Mohawk's future structure in the regulated electric business. During
1999 and 1998, Niagara Mohawk has worked toward the implementation of all phases
of PowerChoice and has implemented other federal and state orders that promote
deregulation as described below:

POWERCHOICE RATE REDUCTIONS AND RETAIL CHOICE OF ELECTRICITY SUPPLIER. The
PowerChoice agreement established a five-year electric rate plan that reduces
class average residential and commercial prices by an aggregate of 3.2% over
the first three years, beginning September 1, 1998. On September 1, 1999,
Niagara Mohawk implemented its second phase of rate reductions. The reduction
in prices includes certain savings that result from approved reductions of the
GRT. Industrial customers are currently receiving average reductions of 25%
relative to 1995 tariffs; this decrease includes discounts previously offered
to some industrial customers through optional and flexible rate programs. As
part of PowerChoice, Niagara Mohawk has retained the flexibility to address
specific competitive challenges for energy intensive customers through
individual rate negotiations.

Effective August 1, 1999, all of Niagara Mohawk's customers were able to choose
their electricity supplier. As of December 31, 1999, 6,658 (4.25%) of Niagara
Mohawk's commercial and industrial customers or approximately 14.56% of eligible
load, and 4,325 (0.31%) residential customers or approximately 0.36% of eligible
load, have chosen an electricity supplier other than Niagara Mohawk. See "FERC
Order 888 - Open Access" below for a discussion of open transmission access as
a result of the formation of the NYISO. Niagara Mohawk will continue to
distribute electricity through its transmission and distribution systems for all
customers, regardless of supplier, and will be provider of last resort for those
customers who do not exercise their right to choose a new electricity supplier.
If a customer chooses an alternative supplier, Niagara Mohawk, as allowed under
PowerChoice, will continue to charge the customer for delivery of the energy and
for a non-bypassable CTC charge. Niagara Mohawk will also give a credit to the
customer for any services provided by the alternative energy supplier that were
provided by Niagara Mohawk in the past.

During the term of the PowerChoice agreement, Niagara Mohawk is permitted to
defer certain incremental costs associated primarily with environmental
remediation, nuclear decommissioning and related costs, and changes in laws,
regulations, rules and orders. In the fourth and fifth years of the rate plan,
Niagara Mohawk can request an annual increase in prices subject to a cap of 1%
of the all-in price, excluding commodity costs (e.g., transmission,
distribution, nuclear, and forecasted CTC). In addition to the price cap, the
PowerChoice agreement provides for the recovery of deferrals established in
years one through four and the generation sale incentive. See Part II, Item 8.
Financial Statements and Supplementary Data - Note 2. Rate and Regulatory Issues
and Contingencies - Deferred Loss on the Sale of Assets, for a discussion of the
generation sale incentive. The aggregate of the price cap increase and recovery
of deferrals is subject to an overall limitation of general inflation. Any
remaining unamortized deferrals at the end of year five will be recovered over
a period not to exceed five years beginning in year six.

Beginning in year four of PowerChoice, Niagara Mohawk can continue to recover
the cost variations in the indexed swap contracts entered into as part of the
MRA, resulting from the indexing provisions of these contracts. As these
indexed swap contracts and other contracts expire, the fluctuations in market
price of unhedged energy will be billed to customers through a commodity
adjustment clause in the CTC. Niagara Mohawk may need to reassess its hedging
strategy if the PSC renders a decision regarding provider of last resort.

The PowerChoice agreement further provides that Niagara Mohawk shall have a
reasonable opportunity to recover its stranded costs, including those associated
with the MRA and the contracts entered into as part of the MRA, through a CTC
and, under certain circumstances, through exit fees or in rates for back up
service. See "FERC Order 888 - Stranded Cost Recovery in the Case of
Municipalization" for a further discussion of stranded costs and exit fees.
Niagara Mohawk's rates under PowerChoice are designed to permit recovery of the
MRA regulatory asset and to permit recovery of, and a return on, the remainder
of its assets, as appropriate.

GENERATION ASSET SALES. Niagara Mohawk has completed the sale of its
coal-fired generation plants, its hydro generation plants, and its oil and
gas-fired generation plant at Oswego. Niagara Mohawk has also announced an
agreement to sell its Albany oil and gas-fired generation plant. Niagara Mohawk
expects to complete the Albany sales transaction in the first quarter of 2000.
In May 1999, Niagara Mohawk entered into an agreement with Central Hudson Gas &
Electric Corporation ("Central Hudson"), subject to regulatory approval, to sell
its interest in the Roseton plant to Central Hudson, at approximately net book
value by no later than January 1, 2003. For a further discussion of these
sales, see Part II, Item 8. - Financial Statements and Supplementary Data, Note
2. - Rate and Regulatory Issues and Contingencies. For a discussion on how
Niagara Mohawk used the proceeds from the sale of its generation assets, see
"Liquidity and Capital Resources."

Niagara Mohawk signed agreements with the buyers of the plants for energy and
capacity at negotiated prices, which are above market, based on current energy
price forecasts. While the PPAs with the buyers of the formerly owned fossil
and hydro assets, which were entered into as an integral part of the sales, are
above market, they are designed to help Niagara Mohawk meet rate reduction and
price cap commitments as well as expected demand as the provider of last resort.
The PPAs that convert to either swap agreements or swaptions (swap agreement
with a call option) act as hedges against a substantial rise in power costs.
See Part II, Item 8. - Financial Statements and Supplementary Data - Note 2. -
Rate and Regulatory Issues and Contingencies, Note 8. - Commitments and
Contingencies, and Note 9. - Fair Value of Financial and Derivative Financial
Instruments, for a further discussion of the terms of these agreements.

Niagara Mohawk expects to incur a net loss, mainly attributable to the Oswego
oil and gas-fired plant, on the sale of the fossil and hydro generation assets
of approximately $150 million. The PowerChoice agreement provides for deferral
and future recovery of the net losses resulting from the sale of the assets.
For a further discussion of the loss incurred on these sales, the regulatory
treatment of such loss, and the factors that may cause the amount of loss to
change, see Part II, Item 8. Financial Statements and Supplementary Data, Note
2. - Rate and Regulatory Issues and Contingencies.

After the fossil and hydro sales are completed, Niagara Mohawk has agreed not
to own any non-nuclear generation assets in the state of New York, subject to
certain exceptions provided in the PowerChoice agreement.

The PowerChoice agreement stipulated that absent a statewide solution, Niagara
Mohawk would file a detailed plan for analyzing other proposals regarding its
nuclear assets, including the feasibility of an auction, transfer and/or
divestiture of such facilities, within 24 months of PowerChoice. On June 24,
1999, Niagara Mohawk announced an agreement to sell its nuclear generation
assets to AmerGen. The sale to AmerGen was subject to a previously existing
agreement among the five co-owners of Unit 2 that gives the co-owners the right
to match a third-party purchase offer. On December 21, 1999, RG&E, a 14%
co-owner of Unit 2, submitted a notice stating it would match the AmerGen offer.
On January 26, 2000, the PSC Staff had informed the ALJ and all parties,
including Niagara Mohawk, that they believed the terms of the proposed nuclear
sale were not in the public interest. The PSC Staff is continuing its
discussions with AmerGen, as well as exploring other options, including
giving other interested parties the opportunity to put forth competing
proposals. Niagara Mohawk cannot predict the outcome of this proceeding, but
is committed to pursue the sale of Unit 1 and Unit 2. Notwithstanding this
commitment, because of the regulatory hurdles that must be overcome, Niagara
Mohawk does not believe that such a sale is any more likely to occur than
other possible scenarios, including the possible continued operation of the
plants by Niagara Mohawk for the remainder of their useful lives. For a further
discussion regarding the details of the sale agreement, the status of the sale,
the proposed regulatory and accounting treatment of the announced sale, the
PPAs signed as part of the agreement, and the treatment under PowerChoice in
the event a sale does not occur, see Part II, Item 8. - Financial Statements
and Supplementary Data, Note 2. - Rate and Regulatory Issues and Contingencies,
Note 3. - Nuclear Operations and Note 9. - Commitments and Contingencies.

THE MRA AGREEMENT. As a result of various federal and state requirements,
Niagara Mohawk was required to enter into contracts to purchase electricity from
IPPs in quantities in excess of its own demand and at prices in excess of those
available to it. In mid-1996, Niagara Mohawk began comprehensive negotiations
to terminate, amend or restate a substantial portion of above-market PPAs in an
effort to mitigate the escalating cost of these PPAs as well as to prepare
Niagara Mohawk for a more competitive environment. These negotiations led to
the MRA and the PowerChoice agreement.

The MRA was consummated on June 30, 1998 with 14 IPPs. The MRA allowed Niagara
Mohawk to terminate, estate or amend 27 PPAs which represented approximately
three-quarters of its over-market purchased power obligations. Niagara Mohawk
terminated 18 PPAs for 1,092 MW of electric generating capacity, restated 8 PPAs
representing 535 MW of capacity and amended 1 PPA representing 42 MW of
capacity. Niagara Mohawk paid the IPP Parties an aggregate of $3.934 billion in
cash, of which $3.212 billion was obtained through a public market offering of
senior unsecured debt, $303.7 million from the public sale of 22.4 million
shares of common stock, and the remainder from cash on hand. In addition,
Niagara Mohawk issued 20.5 million shares of common stock to the IPP Parties.

PowerChoice provided that the MRA and the contracts executed as part of the MRA
were prudent and accordingly, PSC approval of PowerChoice allowed Niagara Mohawk
to record a regulatory asset for the costs of the MRA, which is being amortized
over a period generally not to exceed ten years. Niagara Mohawk's rates under
PowerChoice were designed to permit recovery of the MRA regulatory asset. In
approving PowerChoice, the PSC limited the estimated value of the MRA regulatory
asset that could be recovered, which resulted in a charge to the second quarter
of 1998 earnings of $263.2 million upon the closing of the MRA. The PowerChoice
agreement, while having the effect of substantially depressing earnings during
its five-year term, substantially improves operating cash flow. The ability of
Niagara Mohawk to improve earnings in the period subsequent to PowerChoice will
depend on the outcome of the regulatory process to set prices at that time.

The MRA has the effect of reducing Niagara Mohawk's IPP payments by more than
$500 million annually as compared to leaving the pre-existing contracts in
place, net of purchases of power at market price. The resulting improvement in
cash flow and the proceeds from the sale of the generation assets have allowed
Niagara Mohawk to repay debt and repurchase Holdings' common stock.

Under the terms of the MRA, Niagara Mohawk has no continuing obligation to
purchase energy from the terminated IPP Parties. The restated contracts with
eight PPAs reflect economic terms and conditions that are more favorable to
Niagara Mohawk than the previous PPAs. See Part II, Item 7A. - Quantitative
and Qualitative Disclosures About Market Risk, and Part II, Item 8. - Financial
Statements and Supplementary Data, Note 8. - Commitments and Contingencies and
Note 9 - Fair Value of Financial and Derivative Financial Instruments, for a
further discussion regarding the remaining payments to the IPP Parties for the
purchase of electric power and the payments made under the swap agreements.

Niagara Mohawk is actively pursuing other opportunities to reduce its payments
to IPPs that were not party to the MRA. Niagara Mohawk is permitted to defer
and amortize the cost of any additional IPP contract buyouts. In 1999, there
have been four IPP contracts for approximately 127 MW terminated for a total
consideration (cash and/or notes) of $229.2 million. Niagara Mohawk estimates
that it will have reduced IPP payments by approximately $60 million annually,
net of purchases of power at market price as a result of these contract buyouts.
Deferred costs associated with IPP buyouts must generally be amortized over
five years, unless PSC approval is obtained for a different amortization
period. Niagara Mohawk retains the annual net savings from the buyouts during
the remaining term of PowerChoice to offset the amortization expense. Niagara
Mohawk is negotiating buyouts and amendments of other IPP contracts, but is
unable to determine the timing and outcome of these negotiations.

FORMATION OF A HOLDING COMPANY STRUCTURE. Niagara Mohawk was reorganized into
a holding company structure in accordance with its Agreement and Plan of
Exchange with Niagara Mohawk Holdings, Inc. on March 18, 1999. The outstanding
shares of Niagara Mohawk's common stock, $1.00 par value, were exchanged on a
share-for-share basis for Holdings' common stock, par value of $0.01. Niagara
Mohawk then became a subsidiary of Holdings. Niagara Mohawk's preferred stock
and debt were not exchanged and remained securities of Niagara Mohawk. The
holding company structure was completed March 31, 1999 with the Niagara Mohawk
dividend transfer of Opinac North America Inc. ("Opinac") to Holdings.

The holding company structure provides Holdings and its subsidiaries with the
financial and regulatory flexibility to compete more effectively in an
increasingly competitive energy industry by providing a structure that can
accommodate both regulated and unregulated lines of businesses (energy related
services and telecommunications). The holding company structure permits
Holdings to participate in unregulated business opportunities as the industry
evolves. The PowerChoice agreement provides for affiliate rules to be abided
by Holdings and its affiliated companies, including the allocation of costs
for providing goods and services.

FERC ORDER 888. In April 1996, FERC issued Order 888, which promotes
competition by requiring that public utilities owning, operating, or controlling
interstate transmission facilities file tariffs which offer others the same
transmission services they provide for themselves, under comparable terms and
conditions. FERC Order 888 required the NYPP to file reformed power pooling
agreements that establish open, non-discriminatory membership provisions and
modify any provisions that are unduly discriminatory or preferential. In
addition, the FERC Order also provides for the recovery of prudent and
verifiable stranded costs where the wholesale customer was able to obtain
alternative power supplies as a result of Order 888's open access mandate.

As a result of Order 888, there have been several developments during the past
few years as follows:

- - OPEN ACCESS
-----------

The NYISO commenced formal operations on December 1, 1999. Niagara Mohawk
views this progress as an important step toward a more competitive market for
wholesale electricity supply service in New York State, consistent with its
PowerChoice restructuring agreement.

Twice annually, Niagara Mohawk will be required to sell to the NYISO all of
its transmission capacity, except such transmission capacity grandfathered
under pre-existing Transmission Service Agreement ("TSAs"), for a subsequent
six month period. In turn, Niagara Mohawk will purchase any additional
transmission capacity it needs through the competitive bid process of the
NYISO. Approximately $70 - $75 million, or three-quarters of Niagara
Mohawk's annual transmission revenues, are derived from the grandfathered
TSAs. These grandfathered TSAs have various expiration dates, with the more
significant TSAs not expiring until 2013 and beyond. Niagara Mohawk expects
that total transmission revenues will decline from $100 million in 1999 to
$75 million in 2000, which is due to the transition from Niagara Mohawk's
transmission tariffs to the NYISO tariffs. Niagara Mohawk cannot determine
the long-term impact of the NYISO on its transmission revenues due to lack
of market experience in pricing and capacity needs.

- - STRANDED COST RECOVERY IN THE CASE OF MUNICIPALIZATION
------------------------------------------------------

Order 888 stated that it would provide for the recovery of prudent and
verifiable wholesale stranded costs where the wholesale customer was able to
obtain alternative power supplies as a result of Order 888's open access
mandate. Order 888 left to the states the issue of retail stranded cost
recovery. Where newly created municipal electric utilities required
transmission service from the displaced utility, the FERC stated that it
would entertain requests for stranded cost recovery since such
municipalization is made possible by open access. The FERC also reserved
the right to consider stranded costs on a case-by-case basis if it appeared
that open access was being used to circumvent stranded cost review by any
regulatory agency.

In November 1997, FERC issued Order 888-B. This Order clarified that the
FERC recognizes the existence of concurrent state jurisdiction over stranded
costs arising from municipalization. The FERC acknowledged in Order 888-B
that the states may be first to address the issue of retail-turned-wholesale
stranded costs, and stated that it will give the states substantial deference
where they have done so.

In approving PowerChoice, the PSC authorized changes to Niagara Mohawk's
Retail Tariff providing for the recovery of stranded costs in the case of
municipalization regardless of whether the new municipal utility requires
transmission service from Niagara Mohawk. The calculation of stranded costs
is governed by this Retail Tariff, which became effective on April 6, 1998.
A number of communities served by Niagara Mohawk are considering
municipalization and have requested an estimate of their stranded cost
obligation.

The Village of Lakewood ("Lakewood") is considering municipalization. In
August 1997, Niagara Mohawk provided Lakewood with an estimate of its
stranded cost obligation in response to a formal request under FERC Order
888. In June 1998, Lakewood filed a petition with FERC seeking a
determination that it would not be responsible for any of Niagara Mohawk's
stranded costs if it created a new municipal electric system.

On December 11, 1998, the FERC issued an order granting Niagara Mohawk's
request for clarification that Order 888 does not preempt the exit fee
provision of the Retail Tariff and directing that the Lakewood case be held
in abeyance pending the resolution of Lakewood's stranded cost obligation
under Niagara Mohawk's Retail Tariff.

During 1999, the PSC established a formal proceeding in this matter. Niagara
Mohawk filed its direct case on September 3, 1999, which supported a revised
estimate of exit fees of $18.0 million. Lakewood filed its direct case on
October 18, 1999, which supported an exit fee of approximately $5 million.
The PSC Staff filed their direct case on October 25, 1999, which supported an
exit fee of $15.6 to $16.7 million. Rebuttal testimony was filed on November
10, 1999 and a hearing for the purpose of cross-examination of all testimony
was held on December 1 and 2, 1999. Niagara Mohawk expects the PSC to render
a decision by the second quarter of 2000. Niagara Mohawk is unable to
predict the outcome of this matter.

While the municipalization of Lakewood would not have a material impact on
Niagara Mohawk's results of operation and financial position, the outcome of
this matter will likely define the methodology to determine exit fees. There
have been other challenges to the determination and recovery of stranded
costs through the application of CTCs and exit fees as follows:

In early October 1998, the Alliance for Municipal Power ("AMP"), a group of
21 towns and villages in St. Lawrence and Franklin Counties pursuing
municipalization, and Alfred P. Coppola ("Coppola"), a Councilman from the
city of Buffalo, commenced a proceeding in Albany County Supreme Court that
challenged the PSC's decision to approve PowerChoice and the PSC's decision
that denied the petitions of Alliance for Municipal Power and Coppola for
rehearing before the Commission. The proceeding sought to vacate the
decision of the PSC approving PowerChoice provisions relating to the
determination and recovery of strandable costs through the application of
a competitive transition charge and exit fees. The PSC has made a motion to
dismiss the proceeding in this matter. On March 11, 1999, the Albany County
Supreme Court dismissed in its entirety the petition of Coppola and also
dismissed AMP's petition to the extent that it challenged the determination
and recovery of stranded costs through the application of CTCs and exit fees.
However, the Court did order the PSC to respond to AMP's claim that the PSC
failed to act on discovery requests seeking information about exit fees.
Niagara Mohawk has provided AMP with an updated exit fee estimate of $150
million (PSC method) to $272 million (FERC method). The range is dependent
on whether the formula prescribed by the PSC in PowerChoice or the method
defined by FERC is used. During the first quarter of 1999, AMP filed a
motion to re-argue with the Supreme Court and has also filed a notice of
appeal from the decision of the lower court. On June 29, 1999, the Albany
County Supreme Court denied AMP's motion to re-argue and renew the case.
AMP failed to perfect on a timely basis, its appeal, which failure may
be excused by the court for good reason. Niagara Mohawk is unable to predict
what future actions, if any, AMP will take with respect to this matter. If
these 21 communities withdrew from Niagara Mohawk's system, Niagara Mohawk
would experience a potential revenue loss of approximately two percent per
year. In addition, the impact on Niagara Mohawk's electric margin is
considered to be immaterial. However, suspension of PowerChoice or
renegotiation of its material terms could have a material adverse effect
on Holdings and Niagara Mohawk's results of operations, financial condition,
and future cash flows.

Niagara Mohawk has also prepared exit fee stranded cost estimates for several
other municipalities and customers, including the city of Buffalo. Niagara
Mohawk is unable to predict whether these other municipalities or customers
will pursue a withdrawal from Niagara Mohawk's system or the amount of
stranded costs it may receive as a result of any withdrawals.

FERC ORDER 2000. In December 1999, FERC issued Order 2000, which requires all
public utilities that own, operate or control interstate electric transmission
to file a proposal for a Regional Transmission Organization ("RTO") by October
15, 2000. Alternatively, FERC Order 2000 requires such utilities to provide a
description of any efforts made by the utility to participate in an RTO, the
reasons for not participating and any obstacles to participation, and any plans
for further work toward participation. RTOs are required to be operational by
December 15, 2001. Niagara Mohawk is currently evaluating FERC Order 2000
and believes that the current NYISO structures provides for much of the FERC
mandate under Order 2000. However, at this time, it is difficult to determine
how the NYISO may be impacted by an RTO and what financial consequences, if
any, may result from the formation of an RTO.

OTHER REGULATORY RESTRUCTURING PROCEEDINGS. The PSC continues to assess other
functions in the regulated electric and gas business to lower consumer rates and
increase customer choice. The PSC is considering opening competition to such
functions as metering, billing, collections and customer service. On January
13, 1999, the PSC adopted a set of Uniform Business Practices for Retail Access
designed to streamline and make more uniform the manner in which the local
utilities interact with natural gas and electricity marketers, energy services
companies and customers who purchase energy in New York State's evolving
competitive market.

During the latter part of 1999, the PSC required the New York State utilities
to file tariffs providing a backout credit against utility prices to large
electric customers (greater that 50KW) choosing to have their meter services
performed by someone other than their local utility. The backout credit is an
estimate of costs the utilities incur to provide meter services to these
customers. The PSC has stated a preference for using long run avoided costs to
establish backout credits, and in the absence of long run avoided cost
estimates, the use of embedded, or fully allocable costs of the avoided
activities. Embedded costs may exceed the costs the utility could actually
avoid when not providing a service to customers that have chosen an alternative,
creating stranded costs. The PSC has postponed the implementation of these
rates until March 29, 2000. Due to the limited scope of the PSC's order on
metering, the impact on Niagara Mohawk's results of operations should be
minimal. The exposure could grow, however, if the scope of the metering
proposal is expanded, or other services are required to be opened to
competition using embedded cost as a backout credit.

Niagara Mohawk will continue to participate with the PSC and other parties as
New York State moves forward with a competitive utility industry, but it cannot
predict the outcome of the results and the impact on its PowerChoice agreement.

OTHER FEDERAL AND STATE REGULATORY INITIATIVES
- ----------------------------------------------

GAS MULTI-YEAR RATE AND RESTRUCTURING PROPOSAL. Niagara Mohawk filed a
three-year gas rate and restructuring proposal on March 11, 1999, in
anticipation of the expiration of its 1996 three-year gas rate settlement
agreement, which expired on November 1, 1999. Niagara Mohawk is currently
negotiating with the PSC and other parties, but has not reached a final
agreement. However, on October 15, 1999, and January 12, 2000, the PSC
approved an interim arrangement that freezes delivery rates at current levels,
subject to refund if the permanent rates are lower and allows the pass through
to customers the benefits of lowered pipeline costs. In addition, the interim
arrangement minimizes Niagara Mohawk's exposure to stranded costs. The interim
agreement also included provisions for the implementation of both unbundled gas
rates and a return to a full gas cost collection mechanism (gas adjustment
clause "GAC") effective November 1, 1999. In addition, Niagara Mohawk is
allowed to recover all commodity costs along with fixed capacity costs for
capacity actually used to serve customers. It also provides that, pending
resolution of the issue in that case, costs for capacity upstream of CNG that
are not actually required for sales customer demands or offset by assignment
and secondary market release (stranded capacity costs) are not recoverable
beginning November 1, 1999. However, the potential for stranded costs are not
considered material to Niagara Mohawk's results of operations or financial
condition. The exposure may increase in the future as additional customers
select alternative suppliers. Niagara Mohawk is continuing to work with the
PSC and other interested parties to reach a final settlement, but it cannot
predict the timing or outcome of such a settlement.

FUTURE OF THE NATURAL GAS INDUSTRY. In November 1998, the PSC issued its Policy
Statement concerning the Future of the Natural Gas Industry in New York State
and Order Terminating Capacity Assignment ("PSC Policy Statement"). The PSC
envisions a transitional time frame of three to seven years for local gas
distribution companies ("LDC") to exit the business of purchasing natural gas
(the "merchant" function). The PSC established a process comprising three basic
elements, to be pursued in parallel in the exiting of the merchant function:

1. Addressing the issues involved in the exiting of the merchant function on
a utility-by-utility basis as part of the LDCs individual rate plans;

2. Collaboration among staff, LDCs, marketers, pipelines and other
stakeholders of generic issues such as operational and reliability issues,
protocols and information systems requiring a status report by April 1,
1999; and

3. Coordination of issues faced by electric utilities, including provider of
last resort issues and a plan to allow competition in other areas, such as
metering, billing and information services.

In December 1998, Niagara Mohawk notified the PSC that its specific operational
and reliability requirements continue to warrant certain mandatory capacity
assignment and inclusion of capacity costs in transportation rates after April
1, 1999. Niagara Mohawk will continue to assign CNG capacity until a final
determination is reached in the current rate and restructuring case. The PSC
noted in its PSC Policy Statement that it will provide LDCs with a reasonable
opportunity to recover these strandable costs if they can demonstrate compliance
with the PSC's directives to minimize such costs.

As a result of the collaborative process established in the PSC Policy
Statement, on August 19, 1999, the PSC issued an order requiring that marketers
serving firm customers have firm, primary delivery point capacity for the five
winter months of November through March, but allowed an alternative for
marketers, only for the 1999 - 2000 heating season, to have firm secondary
delivery point capacity and to pay the LDC a standby charge to provide backup
service. LDCs that implemented this Order would be presumed to have met the
PSC's directive to minimize their stranded costs.

Niagara Mohawk believes that it has taken numerous actions to reduce its
capacity obligations and its potential stranded costs, but is unable to predict
the outcome of this matter. Niagara Mohawk has addressed the issues from the
PSC Policy Statement in its three-year gas rate and restructuring proposal filed
on March 11, 1999 and as noted above, Niagara Mohawk is currently working with
the PSC and other interested parties to reach a final settlement. For a
discussion of Niagara Mohawk's long term supply, transportation and storage
commitments, see Part II, Item 8. - Financial Statements and Supplementary Data,
Note 8. - Commitments and Contingencies.

NRC AND NUCLEAR OPERATING MATTERS. On September 24, 1999, Niagara Mohawk
announced that it had begun a comprehensive program to enhance the operating
performance of Unit 1 and Unit 2. Previous internal and external performance
reviews, including a review by the NRC, outlined the need for operational
improvements. Niagara Mohawk has implemented a phased improvement program
designed to strengthen organizational capability to improve more rapidly and
address challenges more effectively. Niagara Mohawk also established a
contractual partnership with PECO Energy, a partner in AmerGen, to provide
additional management and expertise. Niagara Mohawk incurred approximately
$1.0 million in expense during 1999 for this performance improvement program
and has budgeted an additional $5.9 million in expense and $2.8 million for
capital improvements for the six months ending June 30, 2000. Any delay in the
timing or outcome of the nuclear asset sale will affect the cost of the
improvement program.

Niagara Mohawk also experienced several outages with its two nuclear plants,
including the scheduled refueling outage, during 1999. The following summarizes
the two most significant of the outages:

- - UNIT 1: Unit 1 had a scheduled refueling and maintenance outage that
began on April 11, 1999. During the core shroud reinspection, indications of
crack growth on vertical welds were found. The growth rate identified was
consistent with findings noted in earlier inspections at Unit 1. After
careful examination and analysis, Niagara Mohawk decided to install a repair
modification on two of the shroud's vertical welds. A damaged tie rod,
previously installed to address horizontal shroud cracks, was also identified.
As a result, all four tie rods were repaired to correct a design deficiency.
The plant returned to service on June 16, 1999. The incremental costs
associated with the refueling and maintenance outage at Unit 1 was $10.8
million, including $6.3 million of replacement power costs.

- - UNIT 2: On June 24, 1999, Unit 2 automatically shut down due to a
malfunction in a device that controls water flow level to the reactor vessel.
Unit 2 returned to full power on July 26, 1999. The incremental costs
associated with the outage at Unit 2 were $11.4 million, including $10.6
million of replacement power costs.

PSC STAFF'S TENTATIVE CONCLUSIONS ON THE FUTURE OF NUCLEAR GENERATION. On
August 27, 1997, the PSC requested comments on its staff's tentative conclusions
that beyond the transition period (the period covered by the various New York
utility restructuring agreements, including PowerChoice), nuclear generation
should operate on a competitive basis.

In October 1997, the majority of utilities with interests in nuclear power
plants, including Niagara Mohawk, requested that the PSC reconsider its staff's
nuclear proposal, and the utilities recommended that a more formal process be
developed to address issues relating to competition, sale of nuclear plants,
responsibility for decommissioning, disposal of spent fuel, safety, and
environmental benefits of fuel diversity.

On March 20, 1998, the PSC issued an opinion and order instituting a further
inquiry into the matters addressed in the PSC Staff's tentative conclusions
regarding the treatment of nuclear generation in the future. The Order
concluded that the proposals contained in the Staff Report required more
extensive examination, and directed that the examination begin with a
collaborative process and move to litigation on particular issues if necessary.
A collaborative proceeding commenced on January 20, 1999.

The matters addressed in the inquiry include:

- - Market treatment for nuclear power
- - The feasibility of mandated divestiture and its likely consequences
- - Decommissioning issues
- - Effects of PSC Staff's proposal on municipalities

The proceeding has been delayed due to the PSC Staff's attention devoted to the
sale of Unit 1 and Unit 2.

As noted above, Niagara Mohawk has announced an agreement to sell its nuclear
generation assets, but is unable to determine the outcome of such a sale. See
Part II, Item 8. - Financial Statements and Supplementary Data, Note 2. - Rate
and Regulatory Issues and Contingencies and Note 3. - Nuclear Operations, for a
further discussion of the agreement.

At December 31, 1999, the net book value of Niagara Mohawk's nuclear generation
assets (including materials, supplies and nuclear fuel) was approximately $1.6
billion, excluding the reserve for decommissioning. In addition, Niagara Mohawk
has other nuclear-related assets of approximately $0.5 billion. These assets
include the decommissioning trusts and regulatory assets, primarily related to
the flow-through to customers of prior income tax benefits.

YEAR 2000 READINESS DISCLOSURE
------------------------------

Niagara Mohawk has not experienced any significant problems related to the year
2000-date rollover. In general, however, all problems related to the year
2000-date rollover may not yet have become apparent. There are other critical
dates, such as leap year, that could cause similar computer problems. While
Niagara Mohawk believes its efforts to date have successfully addressed the
problems, there can be no assurance until the passage of time, that no further
problems will occur, including with respect to Niagara Mohawk's third party
business partners.

Niagara Mohawk incurred total year 2000 readiness project costs of $26.0 million
through December 31, 1999 of which $16.3 million was expensed and $9.7 million
was capitalized. Niagara Mohawk estimates that program costs for 2000 will
approximate $4.5 million, of which approximately $3.9 million will be expensed
and $0.6 million will be capitalized.

RESULTS OF OPERATIONS
---------------------

This results of operations section includes the results of both Holdings and
Niagara Mohawk. Holdings' prior period results are the same as Niagara Mohawk's
results, except for the treatment of preferred stock dividends paid by Niagara
Mohawk and the manner in which unregulated business activities are consolidated
in the financial statements. See Part II, Item 8. - Financial Statements and
Supplementary Data, Note 1. - Summary of Significant Accounting Policies, for a
further discussion of the formation of the holding company structure during
1999.

Holdings:
- ---------

Holdings experienced a loss in 1999 of $35.1 million or 19 cents per share, as
compared to a loss of $157.4 million or 95 cents per share in 1998 and earnings
of $145.9 million or $1.01 per share in 1997.

Earnings for 1999 reflect the impact of Niagara Mohawk's lower purchased power
costs, partially offset by increased interest charges, resulting in improved
earnings by $108.0 million or 58 cents per share. However, the amortization of
the MRA regulatory asset had a non-cash adverse earnings impact of $167.5
million or 90 cents per share. Earnings for 1999 were also negatively impacted
by Niagara Mohawk's early redemption of First Mortgage Bonds, Senior Notes and
Medium Term Notes, which required a charge to earnings of $23.8 million or 13
cents per share and is reflected as an extraordinary item. See Part II, Item 8.
- - Financial Statements and Supplementary Data, Note 4. - Capitalization, for a
further discussion of the extraordinary item. As discussed in more detail
below, Niagara Mohawk implemented a Customer Service System in February 1999.
Additionally, earnings in 1999 were reduced by $23.8 million, or 13 cents per
share, because of the costs related to the new Customer Service System, and
by $21.0 million, or 11 cents per share, because of higher bad debt expense.
The repurchase of Holdings' common stock has not had a significant impact on
earnings per share for the year ended December 31, 1999, since earnings per
share is based upon the weighted average shares outstanding. However, the
effect on earnings per share in the future should increase.

Results for 1998 were negatively impacted by a non-cash write-off of $171.1
million or $1.03 per share associated with the portion of the MRA regulatory
asset disallowed in rates by the PSC and by the regulatory treatment of the MRA
regulatory asset. The January 1998 ice storm and the September 1998 windstorm
also negatively impacted 1998 earnings by $50.6 million, or 30 cents per share,
which reflected Niagara Mohawk's estimate of incremental, non-capitalized costs
to restore power and rebuild its electric system. In addition, per share
results for the year ended December 31, 1998, were diluted by the issuance of
42.9 million shares of common stock in connection with the MRA.

Niagara Mohawk:
- ---------------

Niagara Mohawk had a net loss of $2.1 million after the extraordinary item. The
preferred dividend requirements reduced the balance available for common stock
to a greater loss of $38.9 million. This loss as compared to 1998 and 1997 is
explained above in the discussion of Holdings' loss for the same period.

The following discussion and analysis highlights items that significantly
affected Holdings and Niagara Mohawk's operations during the three-year period
ended December 31, 1999. This discussion and analysis is not likely to be
indicative of future operations or earnings, particularly in view of the
consummation of the MRA and implementation of PowerChoice, including the sale of
Niagara Mohawk's generation assets. It should also be read in conjunction with
Item 8. - Financial Statements and Supplementary Data, and other financial and
statistical information appearing elsewhere in this report.

CUSTOMER SERVICE SYSTEM. In mid-February 1999, Niagara Mohawk implemented a
new Customer Service System ("CSS"). The CSS replaced existing order, billing,
collection and other infrastructural systems and is designed to provide
real-time information as well as a more flexible and streamlined billing system.
The new CSS also provides retail access and unbundled bill functionality
required under PowerChoice and addresses Year 2000 compliance. These
capabilities could not be developed in the previous systems.

Niagara Mohawk, like other companies that have implemented similar CSS
projects, has experienced a transition period, characterized by significantly
higher customer call volumes and complaints, billing and data accumulation
issues, and other problems that impact productivity and costs. The
transition was also complicated by changes in the information and choices
provided to customers pursuant to PowerChoice. Niagara Mohawk has taken steps
prior to and during the transition period to prioritize and respond to problems.
Although the more significant billing and data accumulation issues concerning
customers have been addressed, resolution of the remaining transition issues
will continue into 2000.

The CSS transition period presents several financial exposures. Outstanding
accounts receivables have increased and Niagara Mohawk's bad debt expense for
1999 was $64.0 million as compared to $31.7 million in 1998, with the increase
in 1999 primarily attributable to the added exposure to collection risk.
Niagara Mohawk is taking aggressive action to reduce its outstanding accounts
receivable balance relating to this transition period, so that the reserve for
bad debts can be returned to a level appropriate in the normal course of
business. However, the actions available to Niagara Mohawk are more limited
during the heating season (beginning November 1, 1999 through April 15, 2000),
since under the law, it cannot disconnect service to residential customers
unless a 72-hour notice is given to the residential customer.

The PSC has been evaluating the development and implementation costs of the CSS
project, as well as Niagara Mohawk's response to the transition problems
incurred during implementation. The PSC issued an order in January 2000
directing that remaining billing related problems be corrected, with emphasis on
estimated bills, by March 31, 2000. Niagara Mohawk cannot predict the outcome
or financial consequences, if any, of the PSC's inquiry.

Niagara Mohawk has incurred increased costs to complete the transition to CSS.
Costs incurred prior to implementation of CSS in February 1999 were generally
capitalized. Niagara Mohawk has capitalized $56 million through December 31,
1999, for the entire CSS project. Niagara Mohawk expected to incur costs
chargeable to expense in 1999 for maintenance of CSS. Incurred costs are also
expected to be higher in the first several years subsequent to implementation as
knowledge and experience is transferred from the vendor to Niagara Mohawk.
While implementation requirements are diminishing, Niagara Mohawk may face
additional costs if the PSC seeks other retail access-related initiatives that
would require modifications to CSS. Niagara Mohawk cannot predict the costs of
these potential changes. Niagara Mohawk also experienced higher costs in 1999
as a result of implementing retail access for all customers. Niagara Mohawk
incurred $36.6 million in 1999 for total CSS-related charges to expense,
exclusive of bad debts. Niagara Mohawk had expected to spend $11.2 million
during 1999 for maintenance and knowledge transfer activities. Niagara Mohawk
expects to incur additional costs in 2000, as remaining issues are addressed and
enhancements are made. These amounts are expected to be substantially less than
1999 spending.

REVENUES AND SALES
------------------

REGULATED ELECTRIC REVENUES for 1999 were $3,248 million, and were $3,261
million and $3,309 million in 1998 and 1997, respectively.

Regulated electric revenues for 1999 decreased $13.4 million or 0.4% as compared
to 1998. The new CSS system has converted all customers previously billed on a
bi-monthly basis to a monthly basis, which has resulted in an increase in billed
revenue and sales (GWh), with corresponding decreases in accrued unbilled
revenues. In accordance with PowerChoice, Niagara Mohawk recognizes changes in
accrued unbilled electric revenues in its results of operations, whereas, in the
first eight months of 1998, the effects of the changes in accrued unbilled
revenues were deferred. As a result, miscellaneous revenues, which include the
unbilled revenues, have decreased by approximately $13.3 million. Commercial
revenues have decreased in 1999 due to lower rates under the PowerChoice
agreement and due to commercial customers switching energy providers as a result
of open access. When customers choose an alternative supplier of energy,
Niagara Mohawk continues to collect delivery charges and the CTC, which are
reflected as "Distribution of Energy." The GWh that are delivered to the
customers who have chosen an alternative supplier are not included in Niagara
Mohawk's sales amounts. In circumstances where Niagara Mohawk sells energy to
energy service companies for resale, those revenues are included in "Other
Electric Systems." Overall electric revenues were not materially impacted by
open access. Sales to other electric systems were also lower in 1999 primarily
due to lower sales to one utility. Under PowerChoice, revenues may decline
further as customers choose alternative suppliers and Niagara Mohawk no longer
sells energy to energy service companies. However, Niagara Mohawk expects to
incur less purchased power expense, and will be able to recover its stranded
costs through the CTC. See Item 8. - Financial Statements and Supplementary
Data - Electric Statistics, for a summary of electric revenue and sales data for
the years 1997 through 1999.

The $48.3 million or 1.5% decrease in 1998 regulated electric revenues was
primarily due to a decrease in volume and mix of sales of $72.3 million along
with rate reductions under PowerChoice. The decrease was partially offset by
increases in sales of energy to other electric systems and revenue from the
distribution of energy.

REGULATED ELECTRIC KILOWATT-HOUR SALES were 35.4 billion in 1999, 36.4 billion
in 1998 and 37.1 billion in 1997. While sales may continue to decline in 2000
and beyond as customers select alternative energy suppliers, Niagara Mohawk
expects deliveries to remain stable.

Regulated electric sales for 1999 decreased 1.0 billion KWh or 2.8% as compared
to 1998. The decrease is primarily due to a decrease in sales to other electric
systems of 1.9 billion KWh or 53.4% as compared to 1998. Sales to other
electric systems were lower in 1999 primarily due to reduced sales to one
utility. Regulated electric sales were also affected by customers selecting
alternative suppliers and billing customers that had been previously billed
bi-monthly on a monthly basis.

The 1998 decrease of 0.7 billion KWh, or 1.9% as compared to 1997, is related
primarily to a 4.5% decrease in sales to other electric systems. Sales to
ultimate consumers also decreased in 1998 primarily due to warmer weather during
the winter months.

UNREGULATED ELECTRIC REVENUES for 1999 were $217.1 million and were $129.4
million and $86.2 million in 1998 and 1997, respectively.

UNREGULATED ELECTRIC SALES for 1999 were 6.4 billion KWh and were 4.6 billion
KWh and 3.3 billion KWh in 1998 and 1997, respectively.

The unregulated electric revenues and sales are generated entirely from Niagara
Mohawk Energy, Inc. (Niagara Mohawk Energy"). The revenue and sales include
wholesale and retail transactions and reflect Niagara Mohawk Energy's increasing
activity in the competitive energy market.

Detail of the changes in electric revenues and KWh sales by customer group are
highlighted in the table below:

REGULATED GAS REVENUES increased $14.4 million or 2.5% in 1999 primarily as a
result of an increase in residential sales and revenue. The increase in
residential revenues is partly the result of beginning to bill customers on a
monthly basis rather than a bi-monthly basis. Most customers that were billed
on a bi-monthly basis were residential customers. Pursuant to the gas
settlement, change in accrued unbilled revenue are deferred. The increase in
regulated gas revenues is also due to revenue earned from revenue sharing
mechanisms allowed in Niagara Mohawk's gas rates as a result of lowering the
non-commodity cost of gas.

Regulated gas revenues decreased in 1998 by $91.7 million or 14.0% primarily due
to decreased sales to ultimate customers as a result of the migration of
commercial sales customers to the transportation class and due to warmer weather
in the winter months. Regulated gas revenues in 1998 were also negatively
impacted by the regulated gas commodity cost adjustment clause ("CCAC").

Rates for transported gas (excluding aggregation services) yield lower margins
than gas sold directly by Niagara Mohawk. Therefore, sales of gas
transportation services have not had a proportionate impact on earnings,
particularly in instances where customers that took direct service from Niagara
Mohawk move to a transportation-only class. In addition, changes in CCAC
revenues are generally margin-neutral.

REGULATED GAS SALES in 1999, excluding transportation of customer-owned gas and
spot market sales, were 68.6 million Dth, a 5.5% increase from 1998. The
increase in the regulated gas sales is primarily attributable to colder weather
in the first quarter of 1999, as well as the shift to monthly billing described
above, which increased residential sales. Regulated revenues were also
positively impacted by an increase in transportation volumes of 9.4 million Dth
or 7.3% to customers purchasing gas directly from producers. The increases were
partially offset by decreased spot market sales (sales for resale), which are
generally from higher priced gas available to Niagara Mohawk and, therefore,
yield margins that are substantially lower than traditional sales to ultimate
customers.

Regulated gas sales in 1998, excluding transportation of customer-owned gas and
spot market sales, were 65.0 million Dth and a 17.3% decrease from 1997. The
decrease in 1998 was in all ultimate consumer classes, primarily due to the
warmer weather. Regulated gas revenues were also negatively impacted by a
decrease in transportation volumes of 24.9 million Dth or 16.3% to customers
purchasing gas directly from producers mainly as a result of the termination and
restatement of the PPAs as part of the MRA. The decreases were partially offset
by increased spot market sales (sales for resale), which are generally from
higher priced gas available to Niagara Mohawk and, therefore, yield margins that
are substantially lower than traditional sales to ultimate customers.

UNREGULATED GAS REVENUES for 1999 were $31.6 million and were $36.0 million and
$24.3 million in 1998 and 1997, respectively.

UNREGULATED GAS SALES for 1999 were 11.0 million Dth and were 13.9 million Dth
and 6.8 million Dth in 1998 and 1997, respectively.

The unregulated gas revenues and sales are generated entirely from Niagara
Mohawk Energy. Unregulated gas revenues and sales declined in 1999 due to
reduced opportunities in the wholesale market, which were only partially offset
by increases in the retail market.

Changes in gas revenues and Dth sales by customer group are detailed in the

OPERATING EXPENSES
------------------

Niagara Mohawk has taken two significant actions during the last two years that
impact the components of its cost structure. In 1998, the MRA began to have the
effect of lowering purchased power costs from IPPs by more than $500 million
annually, net of purchases of power at market prices, while creating a
regulatory asset that increases amortization expense by approximately $386.5
million per year and increasing interest expense due to the debt incurred to
finance the MRA ($3.45 billion). In 1999, Niagara Mohawk sold its hydro and
most of its fossil assets, which reduced costs of ownership such as fuel,
operating costs, property taxes and depreciation. However, Niagara Mohawk
entered into purchase power contracts with the buyers of the formerly owned
fossil and hydro assets, which were entered into as an integral part of the
fossil/hydro sales, that increased its electricity purchased power costs by
$125.4 million through December 31, 1999. However, this increase was partially
offset by lower fuel costs, which resulted in a net reduction in margin of
approximately $84 million. These purchase power contracts mainly expire in
2003. The proceeds from the sale of assets, combined with the improved cash
flow resulting from the MRA, enabled Niagara Mohawk to reduce debt by over $1.1
billion in 1999, which will reduce interest expense in the future.

Niagara Mohawk's FUEL FOR ELECTRIC GENERATION decreased $50.3 million or 21% in
1999 primarily due to the sale of the two coal-fired generation plants in June
1999 and the sale of the oil and gas-fired generation plant at Oswego in October
1999. Generation from Niagara Mohawk's two nuclear plants was reduced due to
the two significant outages. See "NRC and Nuclear Operating Matters" above for
a discussion of these outages. The decrease in fuel costs was partially offset
by an increase in the generation at the remaining fossil generation plants. In
accordance with PowerChoice, the electric fuel adjustment clause was
discontinued. The fuel adjustment clause provided an adjustment to the
customer's bill if the cost of fuel varied from a specified unit cost. In 1999,
Niagara Mohawk recorded a $3.0 million liability to customers resulting from PSC
audit adjustments of prior years fuel costs. Niagara Mohawk's fuel for electric
generation will continue to decrease in 2000 as the remaining generation assets
are sold.

Niagara Mohawk's ELECTRICITY PURCHASED decreased $195 million or 19.5% in 1999,
as a result of reduced purchases and payments to IPPs. The decrease in IPP
purchases is primarily the result of the MRA, which became effective June 30,
1998, and has had the impact of lowering Niagara Mohawk's average unit cost of
purchased power. The decrease is partially offset by purchases under PPAs from
Niagara Mohawk's previously owned fossil and hydro generation plants. Niagara
Mohawk also increased its electricity purchases from other utilities and the
NYISO in 1999 to meet its remaining load requirements. Niagara Mohawk
anticipates that purchases from other utilities will decrease in the future and
that these purchases will be made through the NYISO at market prices. Future
IPP costs will be further reduced as Niagara Mohawk continues to negotiate
settlements with other IPPs. However, purchased power costs will trend upward
in the future as Niagara Mohawk's generation asset sales are completed and
supply from owned generation is replaced by purchased power. See Part II, Item
8. - Financial Statements and Supplementary Data - Note 8. - Commitments and
Contingencies, for a discussion of the PPAs that Niagara Mohawk is committed to
at December 31, 999.

Regulated electric fuel and purchased power costs decreased in 1998 by 12.3% or
$173.6 million. The decrease is mainly the result of decreased purchases from
the IPPs of $321.9 million. Of this amount, $80 million relates to net
reductions in purchases from IPP Parties for the period between the closing of
the MRA to the PowerChoice implementation date, which were deferred for future
rate making disposition because the time lag between these events was not
contemplated in the PowerChoice agreement. The decrease in IPP purchases is
primarily the result of the MRA agreement. (See "The MRA Agreement" above).
Other purchased power costs decreased $8.2 million. As a result, Niagara
Mohawk's load requirements were met to a greater extent from internal sources,
which resulted in an increase in fuel costs of $58.9 million as compared to
1997.

The above table presents the total costs for purchased electricity, while
reflecting only fuel costs for Niagara Mohawk generation. Other costs of power
production, such as property taxes, other operating expenses and depreciation
are included within other income statement line items.

Holdings' FUEL FOR ELECTRIC GENERATION and ELECTRICITY PURCHASED for 1999 is
explained by Niagara Mohawk's activity, as well as an increase in unregulated
supply costs of $69.3 million or 50.8%, primarily due to increased sales
requirements.

Niagara Mohawk's total COST OF GAS PURCHASED decreased 2.0% in 1999 and
decreased 21.3% in 1998. The cost fluctuations generally correspond to sales
volume changes, as well as a decrease in gas prices. Niagara Mohawk sold 1.8,
4.5, and 2.5 million Dth on the spot market in 1999, 1998, and 1997,
respectively. The total cost of gas decreased $5.4 million in 1999. This was
the result of a 2.7% decrease in the average cost per Dth purchased ($7.6
million), a $4.5 million decrease in Dth purchased for spot market sales (sales
for resale), which are generally from higher priced gas, and therefore, yield
margins that are substantially lower than traditional sales to ultimate
consumers, and a $16.9 million decrease in purchased gas costs and certain other
items recognized and recovered through the CCAC. These decreases were offset by
a 6.4 million increase in Dth purchased and withdrawn from storage for ultimate
consumer sales ($23.6 million).

The total cost of gas decreased $73.5 million in 1998. This was the result of
a 19.3 million decrease in Dth purchased and withdrawn from storage for ultimate
consumer sales ($71.7 million), a 1.3% decrease in the average cost per Dth
purchased ($3.5 million) and a $1.0 million decrease in purchased gas costs and
certain other items recognized and recovered through the CCAC. These decreases
were partially offset by a $2.7 million increase in Dth purchased for spot
market sales.

Holdings' GAS PURCHASED expense reflects Niagara Mohawk's activity, as well as a
decrease of $4.8 million during 1999 primarily as a result of lower unregulated
sales.

OTHER OPERATION AND MAINTENANCE EXPENSE for Holdings and Niagara Mohawk have
decreased $37.4 million and $48.7, respectively in 1999. Expenses in 1999 have
decreased in part as a result of the sale of the fossil and hydro generation
assets. Partially offsetting these decreases are incremental costs associated
with the implementation of CSS as discussed above, as well as an increase in bad
debt expense of $32.2 million. Operation and maintenance expense in 1998
reflect two major storms totaling approximately $80.2 million in incremental
costs.

DEPRECIATION AND AMORTIZATION EXPENSE for both Holdings and Niagara Mohawk have
decreased approximately $10.4 million during 1999 primarily as a result of the
sale of Niagara Mohawk's two coal-fired generation plants, its hydro generation
plants and its oil and gas-fired generation plant at Oswego. However, this
decrease is partially offset as a result of placing in service several computer
system projects with depreciable lives that are significantly shorter than
typical transmission and distribution assets.

OTHER TAXES for both Holdings and Niagara Mohawk have decreased as compared to
1998 as a result of a reduction in the New York State GRT tax rate beginning
in October 1998, as well as a reduction in property taxes of $31.9 million in
connection with the sale of Niagara Mohawk's two coal-fired generation plants,
its hydro generation plants, and its oil and gas-fired plant at Oswego.

Other taxes decreased by $11.5 million in 1998 primarily due to a reduction in
GRT taxes of $17.6 million as a result of the lower sales revenue.

In approving PowerChoice, the PSC ordered that any savings from any reduction
in the interest associated with the debt issued in connection with the MRA
financing as compared to assumptions underlying Niagara Mohawk's PowerChoice
filing be deferred for future disposition. Holdings and Niagara Mohawk's OTHER
INCOME decreased in part due to the recording of a regulatory liability relating
to the MRA debt interest rate savings liability of $17.3 million as compared to
1998. The decrease in other income is also due to the recording of
approximately $44.6 million in 1998 on the deferral of MRA financing costs as
ordered by the PSC. These decreases were partially offset by the recording of
the approximately $9.0 million incentive earned under PowerChoice in 1999 on the
sale of the fossil and hydro generation assets.

Although Holdings and Niagara Mohawk's INTEREST CHARGES increased in 1999 mainly
due to the debt incurred to finance the MRA, the annualized level of charges has
decreased since $1.1 billion of debt was repaid during the year. Interest
charges increased in 1998 by $123.3 million after having remained fairly
constant for the years 1996 and 1997. The increase in 1998 is mainly due to the
interest charges incurred on the debt issued in mid-1998 in connection with the
MRA.

DIVIDENDS on Niagara Mohawk's preferred stock did not significantly change
from 1998 to 1999 and from 1997 to 1998. The changes are due to sinking fund
redemptions and variations in dividend rates on the adjustable rate series of
preferred stock. The weighted average long-term debt interest rate and
preferred dividend rate paid, reflecting the actual cost of variable rate
issues, were 7.74% and 7.00%, respectively in 1999 and were 7.46% and 7.00%,
respectively in 1998.

The increase in Holdings and Niagara Mohawk's FEDERAL AND FOREIGN INCOME TAXES
of approximately $86 million, excluding the tax benefit associated with the
extraordinary item, is primarily due to higher book taxable income in 1999 as
compared to 1998. Included in the earnings for 1999 is approximately $16.2
million of previously deferred investment tax credits associated with the two
coal-fired generation plants, the hydro generation plants, and the oil and
gas-fired plant in Oswego, which were sold. Niagara Mohawk believes this
accounting is consistent with applicable tax laws. After adjusting for
Holdings' treatment of Niagara Mohawk's preferred dividends, Holdings' effective
tax rate for 1999 is slightly higher than statutory rates. See Part II, Item 8.
Financial Statements and Supplementary Data - Note 6. Federal and Foreign Income
Taxes for a reconciliation of the tax adjustments.

Niagara Mohawk recorded an EXTRAORDINARY ITEM during 1999 for the early
extinguishment of debt of $23.8 million, net of income taxes. With Niagara
Mohawk's stronger operating cash flows and the proceeds from the sales of its
coal, hydro and its oil and gas generation plants, Niagara Mohawk redeemed over
$820 million in debt prior to its scheduled maturity. The extraordinary item
includes redemption premiums incurred, and the write-off of unamortized debt
expense and debt issuance costs associated with each of the series that was
redeemed.

EFFECTS OF CHANGING PRICES
--------------------------

Niagara Mohawk is especially sensitive to inflation because of the amount of
capital it typically needs and because its prices are regulated using a
rate-base methodology that reflects the historical cost of utility plant.

Holdings and Niagara Mohawk's consolidated financial statements are based on
historical events and transactions when the purchasing power of the dollar was
substantially different than now. The effects of inflation on most utilities,
including Niagara Mohawk, are most significant in the areas of depreciation and
utility plant. Niagara Mohawk could not replace its utility assets for the
historical cost value at which they are recorded on its books. In addition,
Niagara Mohawk would not replace these with identical assets due to
technological advances and competitive and regulatory changes that have
occurred. In light of these considerations, the depreciation charges in
operating expenses do not reflect the cost of providing service if new
facilities were installed. See Construction and Other Capital Requirements
below for a discussion of Niagara Mohawk's future capital requirements.


FINANCIAL POSITION, LIQUIDITY AND CAPITAL RESOURCES
---------------------------------------------------
FINANCIAL POSITION. Holdings and Niagara Mohawk's capital structure at December
31, 1999, and 1998 were as follows:




NIAGARA Holdings and
HOLDINGS MOHAWK Niagara Mohawk
-------- ------------ --------------
% 1999 1999 1998
- ------------------------------ -------- ------------ --------------

Long-term debt . . . . . . . . 61.9 63.3 64.6
Preferred stock of subsidiary. 5.5 - -
Preferred stock. . . . . . . . - 5.6 4.9
Common equity. . . . . . . . . 32.6 31.1 30.5



The culmination of the MRA significantly increased the leverage of Niagara
Mohawk and Holdings. However, the anticipated increased operating cash flow
resulting from the MRA and PowerChoice agreement, including the proceeds from
the sale of the fossil and hydro generation assets, and the planned rapid
repayment of debt, should reduce the leverage in the capital structure of both
entities.

Holdings' 1999 ratio of earnings to fixed charges was 0.95 times. Niagara
Mohawk's ratios of earnings to fixed charges for 1998 and 1997 were 0.57 times
and 2.02 times, respectively. The changes in the ratio are primarily due to the
consummation of the MRA during 1998 and the redemption of over $1 billion in
debt during 1999. The MRA and PowerChoice agreement have the effect of
substantially depressing earnings during its five-year term, while at the same
time substantially improving operating cash flows. The primary result of the
MRA was to convert a large and growing off-balance sheet payment obligation that
threatened the financial viability of Niagara Mohawk into a fixed and more
manageable capital obligation.

EBITDA for the 12 months ended December 31, 1999 was approximately $1,260
million for Holdings, an increase of approximately $0.3 billion compared to the
12 months ended December 31, 1998. This increase is generated almost entirely
by Niagara Mohawk. The improvement in EBITDA is derived primarily from the
impacts of the MRA and PowerChoice. EBITDA represents earnings before interest
charges, interest income, income taxes, depreciation and amortization,
amortization of nuclear fuel, allowance for funds used during construction, MRA
regulatory asset amortization, and extraordinary items. The ratio of EBITDA to
net cash interest for 1999 was 3.2 times as compared to 2.9 times in 1998. Net
cash interest is defined as interest charges (net of allowance for funds used
during construction) and less the non-cash impact of the net amortization of
discount on long-term debt and interest accrued on the Nuclear Waste Policy Act
liability and less interest income. The ratio of EBITDA to net cash interest
also improved due to the impacts of the MRA and PowerChoice and Niagara Mohawk's
debt reduction. EBITDA is a non-GAAP measure of cash flows and is presented to
provide additional information about Holdings and Niagara Mohawk's ability to
meet its future requirements for debt service. EBITDA should not be considered
an alternative to net income as an indicator of operating performance or as an
alternative to cash flows, as presented on the Consolidated Statement of Cash
Flows, as a measure of liquidity.

The sales of the generation plants, especially nuclear, will tend to slightly
lower future EBITDA primarily as a result of the PPAs that Niagara Mohawk
entered into with the new owners of the generation assets.

Niagara Mohawk has been reviewing its capital structure in light of its
scheduled debt reduction program, its divestiture of its electric generation
assets and the changing industry. As a result, Niagara Mohawk filed two
petitions with the PSC on July 1, 1999, to refinance its preferred stock to
take advantage of lower dividend rates, and to purchase Holdings' common stock.
See Part II, Item 8. - Financial Statements and Supplementary Data, Note 4. -
Capitalization, for a further discussion of the two petitions and the actions
taken. The impact on earnings per share as a result of these stock purchases
was not significant for the year ended December 31, 1999, since earnings per
share is calculated using the weighted average of common stock outstanding.
However, the impact on future earnings per share will be more significant.

COMMON STOCK DIVIDEND. Niagara Mohawk's Board of Directors omitted its common
stock dividend beginning the first quarter of 1996. This action was taken to
help stabilize Niagara Mohawk's financial condition and provide flexibility as
Niagara Mohawk addressed growing pressure from mandated power purchases and
weaker sales. In making future dividend decisions, the Board of Directors of
Holdings and Niagara Mohawk will evaluate the relative value to shareholders of
dividend payments or the repurchase of common stock, along with standard
business considerations, their financial conditions, limitations on dividend
payments under the PowerChoice agreement, limitations on common stock dividend
payments in senior bank financing agreement if unsecured debt ratings fall below
current levels, the degree of competitive pressure on its prices, the level of
available cash flow and retained earnings and other investments to be made by
unregulated subsidiaries. For the next several years, Niagara Mohawk expects to
dedicate a substantial portion of its future expected positive cash flow to
reduce debt and buy back Holdings' common stock. See Part II, Item 8. -
Financial Statements and Supplementary Data, Note 4. - Capitalization, for a
discussion of the Holdings' common stock repurchased through December 31, 1999.
The PowerChoice agreement limits the amount of common stock dividends that can
be paid by Niagara Mohawk to Holdings, but does not limit the dividends that
Holdings may pay to its shareholders. The limit under PowerChoice is based upon
the amount of net income each year of Niagara Mohawk, plus a specified amount
ranging from $75 million in 1999 to $100 million in 2000, 2001 and 2002 and
declining thereafter through 2007. The limitation excludes one-time dividends
associated with the sale of Niagara Mohawk's generation assets. The dividend
limitation is subject to review after the term of the PowerChoice agreement.
Furthermore, Niagara Mohawk forecasts that earnings for the five-year term of
the PowerChoice agreement will be substantially depressed, as non-cash
amortization of the MRA regulatory asset is occurring (which asset is being
amortized generally over a ten-year period) and the interest costs on
the IPP debt is the greatest. The ability to improve earnings in the period
subsequent to PowerChoice will depend upon the outcome of the regulatory process
to set prices at that time. Payment of Niagara Mohawk dividends to Holdings
will be subject to the prior rights of holders of Niagara Mohawk preferred
stock, First Mortgage Bonds and other long-term debt.

During 1999, Holdings did not declare or pay any common stock dividends.
During 1999, Niagara Mohawk paid approximately $64 million in cash dividends
to Holdings, as well as the dividend of Opinac. During January 2000, Niagara
Mohawk paid approximately $36 million in cash dividends to Holdings.

CONSTRUCTION AND OTHER CAPITAL REQUIREMENTS. Niagara Mohawk's total capital
requirements consist of amounts for its construction program, see Item 8. -
Financial Statements and Supplementary Data - Note 8. - Commitments and
Contingencies - Construction Program, working capital needs, maturing debt
issues and sinking fund provisions on preferred stock. Niagara Mohawk's annual
expenditures for the years 1997 to 1999 for construction and nuclear fuel,
including related AFC and overheads capitalized, were $290.8 million, $392.2
million and $298.1 million, respectively. These expenditures, excluding nuclear
fuel and AFC, are budgeted to be approximately $219 million for 2000 and $229
million and $230 million in years 2001 and 2002, respectively. If the nuclear
sale does not occur, Niagara Mohawk estimates that it will incur expenditures
for construction and nuclear fuel of $69 million for 2000 and $32 million and
$67 million for 2001 and 2002, respectively. Capital expenditures were lower
in 1999 as compared to 1998 due in part to the sale of several of Niagara
Mohawk's generation assets. In addition, there were higher capital expenditures
in 1998 of approximately $71 million due to the costs incurred to rebuild a
portion of Niagara Mohawk's regulated transmission and distribution facilities
as a result of several storms. The estimates for 2000 and beyond include
amounts relating to Niagara Mohawk's Albany oil and gas-fired generation plant
through March 2000, its nuclear assets through June 2000 and Niagara Mohawk's
25% interest in the Roseton plant through December 2000. The estimate of
construction additions included in capital requirements for the period 2000 to
2002 will be reviewed by management to give effect to the overall objective of
further reducing construction spending where possible. Any change in the
timing or outcome of these remaining generation asset sales and nuclear sale
will effect Niagara Mohawk's capital expenditure requirements.

Mandatory debt and preferred stock retirements are expected to add approximately
another $618.1 million to the 2000 estimate of capital requirements and are
expected to add approximately $631.8, $547.1, $613.8, and $235.5 million in the
next subsequent four years. The 2000 estimate includes $105 million related to
the senior bank facility discussed below, which is classified as current pending
renegotiation of the facility.

See discussion in "Liquidity and Capital Resources" section below, which
describes how management intends to meet its future financing needs.

LIQUIDITY AND CAPITAL RESOURCES. External financing plans are subject to
periodic revision as underlying assumptions are changed to reflect developments
and market conditions. The ultimate level of financing during the period 2000
through 2004 will be affected by, among other things:

- - Niagara Mohawk's competitive position and the extent to which competition
penetrates its markets;
- - changes in electric and gas prices as a result of regulatory proceedings;
- - potential future actions with respect to IPPs not covered under the MRA;
- - uncertain energy demand due to the weather and economic conditions and
obligations to serve as provider of last resort;
- - the cash tax benefits anticipated because the MRA generated a net tax
operating loss carryforward in 1998;
- - levels of common stock repurchases;
- - levels of common dividend payments, if any, and preferred dividend
payments; and
- - the results of the remaining sales of Niagara Mohawk's generation assets.

The proceeds of the sales of the generation assets are subject to the terms of
Niagara Mohawk's mortgage indenture and the note indenture that was entered into
in connection with the MRA debt financing. Niagara Mohawk has petitioned the
PSC to issue up to an aggregate of $400 million in debt to address its financial
needs arising from the recent and prospective termination or restructuring of
additional IPP contracts. Niagara Mohawk plans to issue at least $200 million
of unsecured debt during the first half of 2000. In addition, Niagara Mohawk
may refinance existing debt to take advantage of lower interest rates.

Niagara Mohawk is obligated to use 85% of the proceeds of the sale of its
generation assets to reduce debt outstanding, as outlined in its Senior Note
indenture. In June 1999, Niagara Mohawk announced an agreement to sell its
nuclear assets to AmerGen for $135 million, which is subject to price
adjustments depending on the timing of the closing. Niagara Mohawk has also
announced on October 6, 1999, an agreement to sell its oil and gas-fired plant
at Albany for $47.5 million. In addition, Niagara Mohawk could also receive up
to an additional $11.5 million if the buyer chooses to pursue the redevelopment
of the Albany plant. For a further discussion of the terms and adjustments to
the generation assets sales agreements, see "Generation Assets Sales" above.
With Niagara Mohawk's stronger operating cash flows and proceeds from sales of
its coal, hydro, and its oil and gas facilities, approximately $1.1 billion of
debt was retired in 1999 consistent with debt reduction goals.

Niagara Mohawk has an $804 million senior bank financing with a bank group,
consisting of a $255 million term loan facility, a $125 million revolving credit
facility and $424 million for letters of credit. The letter of credit facility
provides credit support for the adjustable rate pollution control revenue bonds
issued through the NYSERDA. The interest rate applicable to the senior bank
financing is variable based on certain rate options available under the
agreement and currently approximates 6.625% (but is capped at 15%). As of
December 31, 1999, the amount outstanding under the senior bank financing was
$529 million, consisting of $105 million under the term loan facility and $424
million of letters of credit, leaving Niagara Mohawk with $275 million of
borrowing capability under the financing. The senior bank facility term expires
on June 1, 2000. As a result, the amount outstanding on this facility at
December 31, 1999, $105 million, is shown as a current liability on both
Holdings and Niagara Mohawk's balance sheets. This facility is collateralized
by first mortgage bonds. Niagara Mohawk is currently negotiating a new
financing arrangement with a bank group and believes, as a minimum, it will be
able to obtain $424 million for letters of credit prior to the expiration of
the senior bank facility on June 1, 2000. Opinac had an agreement with a bank
providing for letters of credit totaling up to $25 million which in January 2000
was replaced by a $50 million bank facility secured by certain assets of Opinac.
The facility provides for letters of credit and a $10 million line of credit.
The facility expires September 30, 2000, and as of January 31, 2000, supports
approximately $20 million in letters of credit. Opinac is working to extend
the facility beyond September 20, 2000.

Niagara Mohawk has the ability to issue First Mortgage Bonds to the extent that
there have been maturities since June 30, 1998. Through December 31, 1999,
Niagara Mohawk had $60 million in First Mortgage Bonds maturities.

Ordinarily, construction related short-term borrowings are refunded with
long-term securities on a periodic basis. This approach generally results in a
working capital deficit. Working capital deficits may also be a result of the
seasonal nature of Niagara Mohawk's operations as well as the timing of
differences between the collection of customer receivables and the payments of
fuel and purchased power costs. Niagara Mohawk's current working capital
deficit is largely attributable to amounts due in 2000 for the Senior Notes
incurred as part of the MRA and the current classification of $105 million under
the term loan facility. Niagara Mohawk believes it has sufficient cash flow and
borrowing capacity to fund such deficits as necessary in the near term. In
addition, as noted above, Niagara Mohawk is currently negotiating a new
financing arrangement and expects to have it in place before the current
arrangement expires.

Niagara Mohawk has established a single-purpose, financing subsidiary, NM
Receivables LLC, ("NMR")whose business consists of the purchase and resale of an
undivided interest in a designated pool of Niagara Mohawk customer receivables,
including accrued unbilled revenues. See Part II, Item 8. Financial Statements
and Supplementary Data, Note 8. - Commitments and Contingencies for a further
discussion of this customer receivables program.

At December 31, 1999, and 1998, $215.1 million and $150 million, respectively,
of receivables had been sold by NMR to a third party. The total amount of
receivables that can be sold is $300 million. Niagara Mohawk has the discretion
to increase or decrease the actual amount sold, subject to a cap. The undivided
interest in the designated pool of receivables was sold with limited recourse.
The agreement provides for a formula based loss reserve pursuant to which
additional customer receivables are assigned to the purchaser to protect against
bad debts. At December 31, 1999, the amount of additional receivables assigned
to the purchaser, as a loss reserve, was approximately $83.2 million.

In the fourth quarter of 1999, NMR was not in compliance with a certain
statistical ratio relating to the pool of receivables sold. The purchaser has
granted a waiver for this period. While NMR is working to return to compliance
with this ratio, it is possible a non-compliance condition could continue to
exist. NMR is unable to predict whether further waivers would be granted.

In December 1998, Niagara Mohawk received a ruling from the Internal Revenue
Service ("IRS") to the effect that the amount of cash and the value of common
stock that was paid to the terminated IPP Parties was deductible and generated a
substantial net operating loss ("NOL") for federal income tax purposes, such
that Niagara Mohawk did not pay federal income taxes for the 1998 tax year.
Further, Niagara Mohawk has carried back unused NOL to the years ended 1996 and
1997, and also for the years 1988 through 1990, which resulted in a tax refund
of $135 million received in January 1999. As a result of the Agreement and Plan
of Exchange between Niagara Mohawk and Holdings on March 18, 1999, (Part II,
Item 8. - Financial Statements and Supplementary Data, Note 1. - Summary of
Significant Accounting Policies, Corporate Structure and Principles of
Consolidation), Holdings will now be the tax filer to benefit from the remaining
tax carryforward. Holdings anticipates that it will be able to utilize the
remaining $2.6 billion NOL carryforward, as of December 31, 1999, to offset
income earned in the future, before the expiration date of the NOLs in 2019.

Holdings' ability to utilize the NOL generated, as a result of the MRA, could
be limited under the rules of section 382 of the Internal Revenue Code if
certain changes in Holdings' common stock ownership were to occur in the future.
In general, the limitation is triggered by a more than 50% change in stock
ownership during an three-year testing period by shareholders that own,
directly or indirectly, 5% or more of the common stock. For purposes of making
the change in ownership computation, the IPP Parties who were issued common
stock pursuant to the MRA, are likely to be considered a separate 5% shareholder
group, as will the purchasers of common stock in the public offering completed
immediately prior to consummation of the MRA. Under the computational rules
prescribed by applicable Treasury regulations, Niagara Mohawk has experienced an
approximate 17 percentage point owner shift in its stock within the three-year
period ending on June 30, 1998, as a result of the distribution of stock to the
IPP Parties and the public offering. During the year 1999, Niagara Mohawk made
several purchases of its parents' common stock. In total, Niagara Mohawk
purchased 10 million shares of Holdings' common stock, which in aggregate would
be treated under Code Section 382 as a redemption. Holdings has performed the
testing required by Section 382 in connection with the purchases of Holdings'
common stock by Niagara Mohawk. Holdings believes it has experienced an
approximate 21 percentage point owner shift in its stock for the three year
period ending on December 31, 1999, which includes the shares issued as part of
the MRA, as well as the stock repurchased by Niagara Mohawk. Thus, if the IPP
Parties, the purchasers in the public offering, and any other five percent
shareholders collectively experience ownership increases totaling 29 percent
or more during any three year testing period that includes the consummation
dates of the public offering, the MRA and the stock purchases by Niagara
Mohawk, the statutory limit could be breached. The rules for determining a
change in stock ownership for purposes of Code Section 382 are extremely
complicated and in many respects uncertain. A stock ownership change
could occur as a result of circumstances that are not within the control of
Holdings. If a more than 50% change in ownership were to occur, Holdings'
remaining usable NOL carryforward would likely be significantly lower in the
future than the NOL carryforward amount which otherwise would be usable absent
the limitation. Consequently, Holdings' net cash position could be
significantly lower as a result of tax liabilities, which otherwise would be
eliminated or reduced through unrestricted use of the NOL carryforward.

NET CASH FROM OPERATING ACTIVITIES increased $4,035.4 million for Holdings and
$4,039.2 million for Niagara Mohawk in 1999 as compared to 1998, primarily
because the 1998 operating cash included the payments to the settling IPPs to
consummate the MRA. The operating cash flows for 1999 also improved due to
Niagara Mohawk's receipt of federal income tax refunds in January 1999 totaling
approximately $135 million and as expected, operating cash flow improved due to
the impacts of the MRA and PowerChoice.

Holdings and Niagara Mohawk's NET CASH FROM INVESTING ACTIVITIES increased
$937.9 and $1,043.6 million, respectively in 1999 as compared to 1998. These
increases are primarily due to the cash received from the sales of the Huntley
and Dunkirk coal-fired generation assets, the hydro generation assets and the
oil and gas-fired plant at Oswego.

Holdings and Niagara Mohawk's NET CASH FROM FINANCING ACTIVITIES decreased
$4,824.9 and $4,978.5 million, respectively due to the early repayment of debt,
and the dividend and related cash transfer of Opinac to Holdings on March 31,
1999. Financing activities during 1998 were positively impacted by the issuance
of the Senior Notes to finance the MRA.



ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Niagara Mohawk is exposed to various market risks in interest rates, commodity
prices, equity prices and foreign currency valuation because of transactions
conducted in the normal course of business. The financial instruments held or
issued by Niagara Mohawk and Niagara Mohawk Energy, Opinac's energy marketing
subsidiary are used for hedging or cost control and not for trading.

Quantitative and qualitative disclosures are discussed by market risk exposure
category:

- - Interest Rate Risk
- - Commodity Price Risk
- - Equity Price Risk
- - Foreign Currency Exchange Risk

An Exposure Management Committee ("EMC") was set up to monitor and control
efforts to manage these risks. The EMC issues and oversees the Financial Risk
Management Policy (the "Policy") applicable to the regulated company that
outlines the parameters within which corporate managers are to engage in,
manage, and report on various areas of risk exposure. At the core of the Policy
is a condition that Niagara Mohawk will engage in activities at risk, only to
the extent that those activities fall within commodities and financial markets
to which it has a physical market exposure in terms and in volumes consistent
with its core business. That core business is to supply energy, in the form of
electricity and natural gas to customers within Niagara Mohawk's service
territory. The policies of Niagara Mohawk may be revised as its primary markets
continue to change, principally as increased competition is introduced and the
role of Niagara Mohawk in these markets evolves.

Niagara Mohawk Energy maintains a separate Risk Management and Trading Policy
Manual that allows for transactions such as marketing and trading in retail and
wholesale, physically and financially settled, energy based instruments. These
actions expose Niagara Mohawk Energy to a number of risks such as forward price,
deliverability, market liquidity and credit risk. Like Niagara Mohawk's Policy,
the energy trading policy seeks to assure that risks are identified, evaluated
and actively managed.

INTEREST RATE RISK. Niagara Mohawk's exposure to changes in interest rates is
due to its financing through a senior debt facility, several series of
adjustable rate promissory notes and adjustable rate preferred stock. See Note
4. - Capitalization and Note 5. - Bank Credit Arrangements. Under the senior
debt facility, Niagara Mohawk currently has an outstanding term loan of $105
million. The adjustable rate promissory notes are currently valued at $413.8
million, and Niagara Mohawk has $121.3 million outstanding in adjustable rate
preferred stock. Another issue of $150 million of fixed-adjustable rate
preferred stock is fixed at 6.9% for the first five years then adjusts and is
not considered adjustable for this analysis. There is no interest rate cap on
the promissory notes. The interest on the term loan is variable but capped at
15%.

Dividend rates for Niagara Mohawk's preferred stock are indexed to U.S.
government interest bearing securities plus or minus an amount stipulated in
each series and have floors of 6.5% to 7.5% and caps of between 13.5% and 16.5%.
As of December 31, 1999, the rate calculated on the index for each series is
below the floor, therefore, the current rate is equal to the floor. Future
changes in the indexed rate will not result in an exposure to higher dividend
rates until the floor is exceeded. However, for the purposes of the following
sensitivity analysis, a hypothetical one percent increase from the floor
dividend rate is assumed.

Niagara Mohawk also maintains long-term debt at fixed interest rates. A
controlling factor on the exposure to interest rate variations is the mix of
fixed to variable rate instruments maintained by Niagara Mohawk. For 1999 and
1998, adjustable rate instruments comprise 7.5% and 6.4% of total
capitalization; term loan and promissory notes are 9.2% and 7.7% of total
long-term debt. The proportion of adjustable instruments to total
capitalization and debt has increased because of Niagara Mohawk's efforts to
pay down debt in 1999. However, they still remain small in relation to total
capitalization and debt thus, limiting Niagara Mohawk's exposure to interest
rate fluctuations.

If interest rates averaged one percent more in 2000 versus 1999, Niagara
Mohawk's interest expense would increase and income before taxes decrease by
approximately $5.2 million. This figure was derived by applying the
hypothetical one percent variance across the variable rate debt of $518.8
million at December 31, 1999 (the sum of the term loan and promissory notes).
The same one percent increase in Niagara Mohawk's preferred dividend rate
applied against the outstanding balance of $121.3 million would result in an
increase to dividend payments of $1.2 million, assuming that the indexed rate
was between the floor and cap. Under the current rate agreement, prices to
customers are fixed for three years, with limited increases available in years
four and five, if justified by Niagara Mohawk. Changes in the actual cost of
capital from levels assumed in the current rate agreement would create either
exposure or opportunity for Niagara Mohawk until reflected in future prices.

COMMODITY PRICE RISK. Niagara Mohawk is exposed to market fluctuations in the
prices for electricity, natural gas, and oil. Niagara Mohawk does not,
generally, speculate on movements in the underlying prices for these
commodities. Purchases are based on analyses performed in relation to fuel
needs for power generation and customer delivery for electricity and natural
gas. Niagara Mohawk's commodity price risk in regards to power generation will
be eliminated after the sale of the remaining fossil generation plants. Where
possible, Niagara Mohawk takes positions in order to mitigate expected price
increases but only to the extent that quantities are based on expectations of
delivery. Niagara Mohawk attempts to mitigate exposure through a program that
hedges risks as appropriate.

Niagara Mohawk Energy has reduced its amount of trading activity since 1998.
Any trading activities performed are accounted for on a marked-to-market basis
with changes in fair value recognized as a gain or loss in the period of change.
The fair value of open trading positions at December 31, 1999, as well as the
effect of Niagara Mohawk Energy's trading activities were not material to
Holdings' results of operations.

Activities for non-trading purposes generally consist of transactions entered
into to hedge the market fluctuations of contractual and anticipated
commitments. Gas futures and electric forward contracts are used for hedging
purposes. Changes in market value of futures and forward contracts relating to
hedged items are deferred until the physical transaction occurs, at which time,
income or loss is recognized. The fair value of open positions for non-trading
purposes at December 31, 1999, as well as the effect of these activities on
Holdings' results of operations for the same period ending, was not material.

The fair values of futures and forward contracts are determined using quoted
market prices.

The commodity risk exposure of Niagara Mohawk Energy does not constitute a
material risk of loss to Holdings.

With respect to electricity, as customers choose an alternate supplier, Niagara
Mohawk sheds commodity risk. In addition, many large customers that continue
to purchase electricity from Niagara Mohawk have agreed to take market price
risk, further lowering commodity risk. For the remaining customers that have
firm prices, Niagara Mohawk has hedged a significant portion of the commodity
cost through various physical and financial contracts. Under the principles
established in PowerChoice, as these contracts expire, customers who buy
electricity from Niagara Mohawk will bear the commodity price risk for the
amount of energy associated with the expiring contracts.

Niagara Mohawk, as part of the MRA, entered into restated indexed swap contracts
with eight IPPs and financial swap agreements as part of the sale of the Huntley
and Dunkirk coal-fired generation stations. See Note 9. - Fair Value of
Financial and Derivative Financial Instruments, for a more detailed discussion
of these swap contracts.

The fair value of the liability under the swap contracts, based upon the
difference between projected future market prices and projected contract prices
applied to the notional quantities and discounted at 8.5%, is approximately $664
million and is recorded on Niagara Mohawk's balance sheet as a liability for
swap contracts. The discount rate is based upon comparable debt instruments of
Niagara Mohawk. Based upon the PSC's approval of the restated contracts,
including the indexed swap contracts, as part of the MRA and being provided a
reasonable opportunity to recover the estimated indexed swap liability from
customers, Niagara Mohawk has recorded a corresponding regulatory asset. The
amount of the recorded liability and regulatory asset is sensitive to changes in
discount rate, anticipated future market prices and changes in the indices upon
which the indexed swap contracts are based. However, changes in anticipated
future market prices and discount rates will not impact the future cash flow of
Niagara Mohawk when considering the all-in price of the notional quantities of
energy. Specifically, as market prices rise or fall, payments under the indexed
swap contracts move inversely. Similarly, changes in discount rates will not
impact the all-in price. If the indexed contract price were to increase or
decrease by one percent, Niagara Mohawk would see a $15.6 million increase or
decrease in the present value of the projected over-market exposure. If the
market prices were to increase or fall by one percent, Niagara Mohawk would see
a $9.7 million decrease or increase in the projected over-market exposure. If
the discount rate were to increase or decrease to 9.0% or 8.0%, the net present
value of the projected over market exposure would decrease or increase by
approximately $9.3 million.

The cost of natural gas sold to customers fluctuates during the year with prices
most volatile in the winter months. Niagara Mohawk has a policy to reduce the
variability in gas costs over the winter months. Through purchase agreements
limiting or eliminating gas price volatility with three gas suppliers
(approximately 3.2 billion cubic feet ["Bcf"]) and by drawing on stored gas
supplies (approximately 21.5 Bcf), Niagara Mohawk will be able to reduce price
volatility on approximately 50% of the anticipated winter demand.

The rest of the gas needs are met through market-based purchases and are subject
to price fluctuations. On November 1, 1999, the gas commodity cost adjustment
clause ("CCAC") expired and, through an interim agreement with the PSC, was
replaced by a Gas Adjustment Clause ("GAC") that allows for recovery in gas
rates of actual commodity costs and pipeline demand charges. The GAC eliminates
gas commodity and pipeline demand price risk from the earnings of Niagara
Mohawk.

The PSC has mandated that Niagara Mohawk attempt to reduce the price volatility
in the gas commodity portion of customers' bills. In response, Niagara Mohawk's
board has authorized the use of futures, options and swaps to hedge against gas
price fluctuations. The hedging program will be consistent with the Financial
Risk Management Policy and will be monitored by the EMC. Niagara Mohawk intends
to use futures contracts and options traded on the New York Mercantile Exchange
to hedge approximately ten percent of Niagara Mohawk's winter demand.

EQUITY PRICE RISK. The NRC requires nuclear plant owners to place funds in an
external trust to provide for the cost of decommissioning of the contaminated
portions of nuclear facilities. See Note 3. - Nuclear Operations. Niagara
Mohawk has established qualified and non-qualified trust funds for Unit 1 and
Unit 2. At December 31, 1998, these funds were invested in fixed income
securities, domestic equity securities, and cash equivalents. The fixed income
securities are subject to interest rate fluctuations and the equity securities
to price change in the equity markets. The funds asset allocation was designed
to maximize returns commensurate with Niagara Mohawk's risk tolerance. As of
December 31, 1999, the funds were invested primarily in high grade, short-term
commercial paper. The current fund allocation is designed to guarantee
stability and predictability in the fund balances.

During 1999, Niagara Mohawk announced an agreement to sell its nuclear assets.
The agreement to sell the nuclear generation assets includes the transfer of the
decommissioning trust funds, at an agreed amount, to the buyer. In anticipation
of that sale, and to reduce the risk of a detrimental market shift affecting the
funds, Niagara Mohawk converted all decommissioning assets to high grade,
short-term commercial paper in October and November of 1999. The instruments
purchased have specified coupon rates and maturity dates of generally one to
four months. The fund managers can only purchase the commercial paper from a
list of companies pre-approved based on an excellent credit rating. Remaining
cash is invested in an overnight, short-term investment fund. Due to the makeup
of the funds at December 31, 1999, they no longer experience any substantial
risk of loss due to market shifts or credit risk.

FOREIGN CURRENCY EXCHANGE RISK. Holdings has a foreign currency exchange risk
as a result of its investments in Canada through its non-regulated subsidiary.
Translation adjustments due to exchange rate movement across the value of the
subsidiary is reported in Capitalization as a Foreign Currency Translation
Adjustment (see Note 4. - Capitalization) and is a component of Comprehensive
Income, see "Consolidated Statements of Comprehensive Income." In aggregate,
the risk of loss does not pose a material threat to Holdings' consolidated
results of operations or total capitalization.

REPORT OF MANAGEMENT

The consolidated financial statements of Holdings and Niagara Mohawk and their
subsidiaries were prepared by and are the responsibility of management.
Financial information contained elsewhere in this Annual Report is consistent
with that in the financial statements.

To meet its responsibilities with respect to financial information, management
maintains and enforces a system of internal accounting controls, which is
designed to provide reasonable assurance, on a cost effective basis, as to the
integrity, objectivity and reliability of the financial records and protection
of assets. This system includes communication through written policies and
procedures, an organizational structure that provides for appropriate division
of responsibility and the training of personnel. This system is also tested by
a comprehensive internal audit program. In addition, a Corporate Policy
Register and a Code of Business Conduct (the "Code") supply employees with a
framework describing and defining Holdings' overall approach to business and
require all employees to maintain the highest level of ethical standards as well
as requiring all management employees to formally affirm their compliance with
the Code.

The financial statements have been audited by PricewaterhouseCoopers LLP,
Holdings and Niagara Mohawk's independent accountants, in accordance with
generally accepted auditing procedures. In planning and performing its audit,
PricewaterhouseCoopers LLP considered Holdings and Niagara Mohawk's internal
control structures in order to determine auditing procedures for the purpose of
expressing an opinion on the financial statements, and not to provide assurance
on the internal control structures. The independent accountants' audit does not
limit in any way management's responsibility for the fair presentation of the
financial statements and all other information, whether audited or unaudited, in
this Annual Report. The Audit Committee of Holdings' Board of Directors,
consisting of five outside directors who are not employees, meets regularly with
management, internal auditors and PricewaterhouseCoopers LLP to review and
discuss internal accounting controls, audit examinations and financial reporting
matters. PricewaterhouseCoopers LLP, and Holdings and Niagara Mohawk's internal
auditors have free access to meet individually with the Audit Committee at any
time, without management being resent.

REPORT OF INDEPENDENT ACCOUNTANTS

To the Stockholders and Board of Directors of
Niagara Mohawk Holdings, Inc. and
Niagara Mohawk Power Corporation


In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of income and retained earnings, of comprehensive income
and of cash flows present fairly, in all material respects, the financial
position of Niagara Mohawk Holdings, Inc. and its subsidiaries ("Holdings") at
December 31, 1999 and 1998, and the results of their operations and their cash
flows for each of the three years in the period ended December 31, 1999 and the
accompanying consolidated balance sheets and the related consolidated statements
of income and retained earnings, of comprehensive income and of cash flows
present fairly, in all material respects, the financial position of Niagara
Mohawk Power Corporation and its subsidiaries ("Niagara Mohawk") at December 31,
1999 and 1998, and the results of their operations and their cash flows for each
of the three years in the period ended December 31, 1999, in conformity with
accounting principles generally accepted in the United States. These financial
statements are the responsibility of management of Holdings and Niagara Mohawk;
our responsibility is to express an opinion on these financial statements 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.

NIAGARA MOHAWK HOLDINGS, INC. AND SUBSIDIARY COMPANIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

CORPORATE STRUCTURE AND PRINCIPLES OF CONSOLIDATION: Niagara Mohawk Holdings,
Inc. ("Holdings") is a New York corporation. On March 18, 1999, Niagara Mohawk
Power Corporation ("Niagara Mohawk") was reorganized into a holding company
structure in accordance with an Agreement and Plan of Exchange between Niagara
Mohawk and Holdings. Niagara Mohawk's outstanding common stock was exchanged on
a share-for-share basis for Holdings' common stock. Niagara Mohawk's preferred
stock and debt was not exchanged as part of the share exchange and continue as
obligations of Niagara Mohawk.

On March 31, 1999, Niagara Mohawk distributed its ownership in the stock of
Opinac North America, Inc. ("Opinac") as a dividend to Holdings. As a result,
the net assets and accumulated other comprehensive income of Opinac are no
longer included in Niagara Mohawk's consolidated balance sheet as of December
31, 1999. The dividend completed the holding company structure, with Holdings
owning 100% of the common stock of its two subsidiaries, Niagara Mohawk and
Opinac. Niagara Mohawk and its subsidiaries manage all regulated activities and
comprise approximately 98 percent of the assets and approximately 94 percent of
the revenues of Holdings. Opinac and its subsidiaries manage all other
activities including an energy marketing company and investments in energy
related services businesses, a development stage telecommunications company, and
a research and development company that has developed and intends to
commercialize new fuel cell and battery technology.

Niagara Mohawk is subject to regulation by the PSC and FERC with respect to its
rates for service under a methodology, which establishes prices, based on
Niagara Mohawk's cost. Niagara Mohawk's accounting policies conform to GAAP,
including the accounting principles for rate-regulated entities with respect to
Niagara Mohawk's nuclear, transmission, distribution and gas operations
(regulated business), and are in accordance with the accounting requirements and
ratemaking practices of the regulatory authorities. In 1996, Niagara Mohawk
discontinued the application of regulatory accounting principles to its fossil
and hydro generation operations.

Holdings' consolidated financial statements include the accounts of Holdings'
and its wholly owned subsidiaries. Niagara Mohawk's consolidated financial
statements include its accounts as well as those of its wholly owned
subsidiaries. Inter-company balances and transactions have been eliminated.
The notes to the Consolidated Financial Statements apply to both Holdings and
Niagara Mohawk unless otherwise stated.

The closing of the MRA, which occurred on June 30, 1998, and the implementation
of PowerChoice on September 1, 1998 have depressed and will continue to
substantially depress earnings during the five-year term of PowerChoice. The
ability of Niagara Mohawk to improve earnings in the period subsequent to
PowerChoice will depend on the outcome of the regulatory process to set prices
at that time. However, operating cash flows have substantially improved. The
closing on the sale of the fossil and hydro generation assets at various times
during the year has also affected the comparability of the financial statements.
See Note 2. for a further discussion of the sales.

ESTIMATES: In order to be in conformity with GAAP, management is required to
use estimates in the preparation of Holdings and Niagara Mohawk's financial
statements.

UTILITY PLANT: The cost of additions to utility plant and replacements of
retirement units of property are capitalized. Costs include direct material,
labor, overhead and AFC. Replacement of minor items of utility plant and the
cost of current repairs and maintenance are charged to expense. Whenever
utility plant is retired, its original cost, together with the cost of removal,
less salvage, is charged to accumulated depreciation.

The output of the co-owned generation units, Roseton Units No. 1 and 2 (which
has a capability of 1,200 MW) and Nine Mile Point Nuclear Station Unit No. 2,
and related expenses are shared in the same proportions as the co-tenants'
respective ownership interests. Niagara Mohawk's share of expenses associated
with these plants are included in the appropriate operating expenses in Niagara
Mohawk's Consolidated Statements of Income.

ALLOWANCE FOR FUNDS USED DURING CONSTRUCTION: Niagara Mohawk capitalizes AFC in
amounts equivalent to the cost of funds devoted to plant under construction for
its regulated business. AFC rates are determined in accordance with FERC and
PSC regulations. The AFC rate in effect at December 31, 1999 was 8.86%. AFC is
segregated into its two components, borrowed funds and other funds, and is
reflected in the "Interest charges" and "Other income" sections, respectively,
in both Holdings and Niagara Mohawk's Consolidated Statements of Income. The
amount of AFC credits recorded in each of the three years ended December 31, in
thousands of dollars, was as follows:




1999 1998 1997
------ ------- ------

Other income . . $5,366 $ 8,626 $5,310
Interest charges 7,252 10,228 4,396



The amount of AFC credits in 1999 for fossil and hydro generation, included in
the total above, is $518,000 as compared to $1,034,000 in 1998 and $1,179,000 in
1997.

DEPRECIATION, AMORTIZATION AND NUCLEAR GENERATION PLANT DECOMMISSIONING COSTS:
For accounting and regulatory purposes, Niagara Mohawk's depreciation is
computed on the straight-line basis using the license lives for its nuclear
class of depreciable property and the average service lives for all other
classes. The percentage relationship between the total provision for
depreciation and average depreciable property was approximately 3.4% to 3.6% for
the years 1997 through 1999. Niagara Mohawk performs depreciation studies to
determine service lives of classes of property and adjusts the depreciation
rates when necessary.

Estimated decommissioning costs (costs to remove a nuclear plant from service in
the future) for Niagara Mohawk's Unit 1 and its share of Unit 2 are being
accrued over the service lives of the units, recovered in rates through an
annual allowance and currently charged to operations through depreciation.
Niagara Mohawk currently recognizes the liability for nuclear decommissioning
over the service life of the plants as an increase to accumulated depreciation.
As discussed in Notes 2 and 3, Niagara Mohawk announced an agreement to sell its
nuclear assets. As par of the agreement, Niagara Mohawk will transfer its
decommissioning liability, as well as the decommissioning funds, which will be
increased by Niagara Mohawk to a specified amount at the time of the transfer.
See Note 3. Nuclear Operations - Nuclear Plant Decommissioning, for more
information on the decommissioning fund. Absent such a nuclear sale, Niagara
Mohawk plans to commence decommissioning of both units using a method which
removes or decontaminates the Units' components properly at that time.

Amortization of the cost of nuclear fuel is determined on the basis of the
quantity of heat produced for the generation of electric energy. The cost of
disposal of nuclear fuel, which presently is $.001 per KWh of net generation
available for sale, is based upon a contract with the DOE. These costs are
charged to operating expense as part of fuel for electric generation.

REGULATED REVENUES: Niagara Mohawk bills its customers on a monthly cycle basis
at approved tariffs based on energy delivered and a minimum customer service
charge. Revenues are determined based on these bills plus an estimate for
unbilled energy delivered between the cycle billing date and the end of the
accounting period. In February 1999, a new customer service billing system was
implemented which converted all customers previously billed on a bi-monthly
cycle to a monthly basis. (See Note 8 "Customer Service System" for a further
discussion of this new system). The unbilled revenues included in accounts
receivable at December 31, 1999 and 1998 were $143.9 million and $205.6 million,
respectively.

In accordance with PowerChoice, Niagara Mohawk recognizes changes in accrued
unbilled electric revenues in its results of operations. Previously, Niagara
Mohawk did not recognize accrued unbilled electric revenues in its results of
operations until authorized and used them to reduce future revenue requirements.
Such amounts were included in "Other Liabilities" pending regulatory
disposition. Under the PowerChoice agreement, $8.6 million of unrecognized
unbilled electric revenues as of September 1, 1998, the implementation date of
PowerChoice, were netted with certain other regulatory assets and liabilities
and any subsequent changes in the estimated unbilled electric revenues are
recognized currently in results of operations.

Pursuant to Niagara Mohawk's 1996 three-year gas settlement, changes in accrued
unbilled gas revenues are deferred. At December 31, 1999 and 1998, $14.6
million and $30.7 million, respectively, of unbilled gas revenues remain
unrecognized in results of operations.

Prior to September 1, 1998, Niagara Mohawk's tariffs included an electric fuel
adjustment clause, such that electricity costs above or below the levels allowed
in approved rate schedules, were billed or credited to customers. Niagara
Mohawk, as authorized by the PSC, charged operations for electricity cost
variances in the period of recovery. Under the PowerChoice agreement, the
electric fuel adjustment clause was discontinued as of September 1, 1998.

The 1996 three-year gas settlement agreement established a gas commodity cost
adjustment clause ("CCAC"). Niagara Mohawk's gas CCAC provides for the
collection or pass back of certain increases or decreases from the base
commodity cost of gas as established in the gas settlement agreement. The
maximum annual risk or benefit to Niagara Mohawk is $2.25 million. All savings
or excess costs beyond that amount flow to ratepayers. The PSC approved an
interim gas rate agreement on October 15, 1999 and January 12, 2000 that
included a provision for the implementation of a return to a full gas cost
collection mechanism and termination of the cost sharing mechanism, effective
November 1, 1999.

UNREGULATED REVENUES: Unregulated revenues and the related costs of gas and
electricity are accrued and recorded in the month of delivery, based on contract
price and nominated natural gas and electricity transmission reservation volumes
sold to customers and purchased from suppliers. Adjustments are made to reflect
actual volumes delivered or purchased when the actual volumetric information
becomes available from the transporters.

FEDERAL INCOME TAXES: As directed by the PSC, Niagara Mohawk defers any amounts
payable pursuant to the alternative minimum tax rules. Deferred investment tax
credits are amortized over the useful life of the underlying property. Deferred
investment tax credits related to the assets that have been sold are taken into
income in accordance with IRS rules. Holdings and its United States'
subsidiaries file a consolidated federal income tax return. Income taxes are
allocated to each company based on its taxable income.

STATEMENTS OF CASH FLOWS: Holdings and Niagara Mohawk consider all highly
liquid investments, purchased with a remaining maturity of three months or less,
to be cash equivalents. The consolidated cash flow statements for Holdings and
Niagara Mohawk have been presented to reflect the closing on the sale of the
fossil and hydro generation assets, such that certain individual line items are
net of the effects of the sale. (For example, the change in materials and
supplies was reduced by the sale of inventory to the buyers of the fossil and
hydro generation assets).

TREASURY STOCK: The PSC approved Niagara Mohawk's petition to purchase up to
$800 million of Holdings' common stock. Holdings' Board of Directors has
approved a program to repurchase twenty million shares through December 31,
2001. The cost to acquire Holdings' common stock by Niagara Mohawk is presented
as "Treasury stock" in Holdings' financial statements and as "Repurchase of
Holdings' common stock" on Niagara Mohawk's financial statements. See Note 4
for a discussion of the stock repurchased during 1999.

EARNINGS PER SHARE: Basic earnings per share ("EPS") is computed based on the
weighted average number of common shares outstanding for the period. Treasury
stock is not considered outstanding and thus, reduces the weighted average
shares outstanding. The number of options outstanding at December 31, 1999,
1998 and 1997 that could potentially dilute basic EPS, (but are considered
antidilutive for each period because the options exercise price was greater than
the average market price of common shares), is immaterial. Therefore, the
calculation of both basic and dilutive EPS is the same for each period.

DERIVATIVES: In June 1998, the Financial Accounting Standards Board (FASB)
issued Statement of Financial Accounting Standards No. 133, "Accounting for
Derivative Instruments and Hedging Activities." The new standard requires
companies to record derivatives on the balance sheet as assets or liabilities,
measured at fair value. Gains or losses resulting from the changes in the
values of the derivatives will be accounted for depending on the use of the
derivative and whether it qualifies for hedge accounting. Holdings and Niagara
Mohawk will be required to adopt this standard in 2001. Niagara Mohawk has
identified swap contracts, entered into as part of the MRA and generation asset
sales agreements, (see Note 9) as derivative instruments and has recorded a
liability at fair value under SFAS No. 80, "Accounting for Futures Contracts."
These swap contracts qualify as hedges of future purchase commitments and will
continue to qualify as hedges under SFAS No. 133. The financial sharing
agreement entered into as part of the agreement to sell Niagara Mohawk's nuclear
generation assets will be a derivative instrument as defined by SFAS No. 133 and
will be recorded upon the closing of such sale. See Note 8 - "Long-term
Contracts for the Purchase of Electric Power - Nuclear Contracts" for a further
discussion of the financial sharing agreement. Holdings and Niagara Mohawk
continue to assess the applicability of this new standard to other contractual
obligations.

ENERGY TRADING: The Emerging Issues Task Force ("EITF") of the FASB reached a
conclusion on Issue No. 98-10, "Accounting for Contracts Involved in Energy
Trading and Risk Management Activities" to be applied for fiscal years beginning
after December 15, 1998. This EITF states that energy trading contracts should
be marked-to-market with the gains and losses included in earnings. Contracts
that are designed as hedges of non-trading activities are outside the scope of
this EITF. Niagara Mohawk's energy contracts and the majority of the marketing
activities of NM Energy are not energy trading as defined by this EITF, and
therefore, Holdings and its subsidiaries do not account for its energy contracts
on a marked-to-market basis.

COMPREHENSIVE INCOME: Comprehensive income is the change in the equity of a
company, not including those changes that result from shareholder transactions.
While the primary component of comprehensive income is reported net income or
loss, the other components of comprehensive income relate to foreign currency
translation adjustments, additional minimum pension liability recognition and
unrealized gains and losses associated with certain investments held as
available for sale. The primary difference in comprehensive income between
Holdings and Niagara Mohawk is the treatment of Niagara Mohawk's preferred
dividends and reported net income or loss.

RECLASSIFICATIONS: Certain amounts from prior years have been reclassified on
the accompanying Consolidated Financial Statements to conform with the 1999
presentation.

Holdings' prior years consolidated financial statements have been prepared from
Niagara Mohawk's prior year consolidated financial statements, except that
accounts have been reclassified to reflect Holdings' structure.



NOTE 2. RATE AND REGULATORY ISSUES AND CONTINGENCIES

Holdings and Niagara Mohawk's financial statements conform to GAAP, including
the accounting principles for rate-regulated entities with respect to its
regulated operations. Substantively, SFAS No. 71 permits a public utility,
regulated on a cost-of-service basis, to defer certain costs, which would
otherwise be charged to expense, when authorized to do so by the regulator.
These deferred costs are known as regulatory assets, which in the case of
Niagara Mohawk are approximately $5.5 billion at December 31, 1999. These
regulatory assets are probable of recovery.

Niagara Mohawk has recorded the following regulatory assets on its Consolidated
Balance Sheets reflecting the rate actions of its regulators:

MRA REGULATORY ASSET

Under PowerChoice, a regulatory asset was established for the costs of the MRA
and represents the costs to terminate, restate, or amend IPP Party contracts.
This regulatory asset is being amortized generally over ten years, beginning
September 1, 1999. Niagara Mohawk's rates under PowerChoice have been designed
to permit recovery of the MRA regulatory asset.

SWAP CONTRACT REGULATORY ASSET

The swap contract regulatory asset represents the expected future recovery of
the swap contract liability. The swap contract liability is the difference
between estimated future market prices and the contract prices for the notional
quantities of power in the restated IPP PPA contracts and in the financial swaps
associated with the PPAs from the sale of the Huntley and Dunkirk coal-fired
generation plants. The portion of this regulatory asset associated with the
restated IPP PPA contracts will be amortized over ten years ending in June 2008,
in accordance with the MRA, as notional quantities are settled. The portion of
this regulatory asset associated with the Huntley and Dunkirk PPAs will be
amortized over the remaining term of the swaps through June 2003. The amount of
this regulatory asset will fluctuate as estimates of future market and contract
prices change over the terms of the contracts. For a further discussion of the
several PPAs and other financial agreements that Niagara Mohawk has entered into
as part of the MRA and the sale of its generation assets, see Note 8 -
"Long-term contracts for the purchase of electric power and Note 9."

REGULATORY TAX ASSET

The regulatory tax asset represents the expected future recovery from ratepayers
of the tax consequences of temporary differences between the recorded book bases
and the tax bases of assets and liabilities. This amount is primarily timing
differences related to depreciation. These amounts are recovered and amortized
as the related temporary differences reverse. In January 1993, the PSC issued a
Statement of Interim Policy on Accounting and Ratemaking Procedures that
required adoption of SFAS No. 109 on a revenue-neutral basis.

IPP BUYOUT COSTS

Niagara Mohawk is also permitted to defer and amortize the cost of any
additional IPP contract buyouts. In 1999, there have been four IPP contracts
for approximately 127 MW terminated for a total consideration (cash and/or
notes) of $229.2 million. Niagara Mohawk estimates that it will have reduced
IPP payments by approximately $60 million annually, net of purchases of power
at market price as a result of the contract buyouts. Deferred costs
associated with IPP buyouts will generally be amortized over five years in
accordance with PowerChoice, unless PSC approval is obtained for a different
amortization period. Niagara Mohawk retains the annual net savings of the
buyouts during the remaining term of PowerChoice to offset the amortization
expense. Niagara Mohawk is negotiating buyouts and amendments of other IPP
contracts. Niagara Mohawk is unable to determine the timing and outcome of
these negotiations.

DEFERRED ENVIRONMENTAL RESTORATION COSTS

The deferred environmental restoration costs regulatory asset represents Niagara
Mohawk's share of the estimated costs to investigate and perform certain
remediation activities at both Niagara Mohawk-owned sites and non-owned sites
with which it may be associated. Niagara Mohawk has recorded a regulatory asset
representing the remediation obligations to be recovered from ratepayers.
PowerChoice and Niagara Mohawk's gas rates decisions provide for the recovery of
these costs over the settlement periods. Niagara Mohawk believes future costs,
beyond the settlement periods, will continue to be recovered in rates. See Note
8. - Environmental Contingencies.

DEFERRED LOSS ON THE SALE OF ASSETS

PowerChoice requires Niagara Mohawk to divest its portfolio of fossil and hydro
generation assets. During 1999, Niagara Mohawk completed the sale its
hydroelectric generation plants, its two coal-fired generation plants and its
Oswego oil and gas-fired plant for $860 million. These assets had a combined
net book value of $956.8 million (including materials and supplies and fuel) at
the time of their sale. In addition, there were purchase price adjustments of
$26.7 million, primarily due to a lower amount of fuel being delivered to the
new owners of the Oswego generation assets than originally anticipated and
provided for in the sales agreement.

On October 6, 1999, Niagara Mohawk announced an agreement to sell its Albany oil
and gas-fired plant to PSEG Power LLC ("PSEG") for $47.5 million. The 400 MW
Albany plant has a net book value of approximately $32.0 million (including
materials and supplies and fuel) as of December 31, 1999. Niagara Mohawk could
also receive up to an additional $11.5 million if PSEG chooses to pursue the
redevelopment of the Albany plant and the redevelopment is in service by July 1,
2003. The agreement with PSEG includes a "Post Closing Property Tax Adjustment"
to be settled on the first ten anniversaries of the closing date. If actual
annual property taxes exceed a predetermined amount, Niagara Mohawk will pay
PSEG. If the property taxes are lower, then PSEG will pay Niagara Mohawk. The
predetermined amount is based upon the taxes paid by Niagara Mohawk at the time
of the sale, which should approximate $6.7 million. During the ten years, the
predetermined amount will be lowered by $0.5 million each year. Niagara Mohawk
is pursuing a reduction in the taxes paid on the facility. No amount has been
reflected in the anticipated proceeds from the sale of Albany for the
redevelopment fee or the post closing property tax adjustment. Niagara Mohawk
expects to complete the Albany sale transaction in the first quarter of 2000.

The sale of the Roseton Steam Station, of which Niagara Mohawk owns 25%, is
being pursued by Central Hudson. The remaining ownership interests are Central
Hudson, the operator of the plant (35%), and Consolidated Edison Company of New
York, Inc. (40%). Although Central Hudson stated that it expects to sell this
plant by early 2001, to assure divestiture of this asset, Niagara Mohawk entered
into an agreement with Central Hudson, subject to regulatory approval, to sell
its interest in the plant to Central Hudson at approximately net book value by
no later than January 1, 2003. Niagara Mohawk's share of the plant has a net
book value of approximately $40.8 million (which includes materials and supplies
and fuel) as of December 31, 1999.

The following table summarizes Niagara Mohawk's electric plant assets as of
December 31, 1999 and 1998, showing the impact on Niagara Mohawk's electric
plant from the completed sales through December 31, 1999:

The PowerChoice agreement provides for deferral and future recovery of net
losses, if any, resulting from the sale of the fossil and hydro generation asset
portfolio. As of December 31, 1999, Niagara Mohawk has recorded a regulatory
asset of $135.2 million for the net loss on the sale of its two coal-fired
generation plants, its hydro generation assets, and its oil and gas fired plant
at Oswego, which includes $3.0 million in employee-related severance costs. The
net loss is included in Niagara Mohawk's balance sheet as "Deferred Loss on the
Sale of Assets." In accordance with PowerChoice, Niagara Mohawk will not earn a
return on the deferred loss during the PowerChoice period. The amount of this
regulatory asset is subject to change as a result of post closing adjustments on
the sales, transaction costs, the accounting treatment relating to the hydro
PPAs, the amount of severance and other costs and the outcome of the sale of the
remaining fossil assets. Niagara Mohawk has petitioned the PSC to defer, as
part of the regulatory asset associated with the sale of the fossil and hydro
generation assets, the amount by which the actual amount incurred on the hydro
PPAs exceeds the forecasted amount reflected in PowerChoice. After all the
fossil and hydro sales transactions have been completed, Niagara Mohawk
estimates that it will have a net loss (stranded costs) of approximately $150
million, including an estimate of the future deferrable hydro payments. Niagara
Mohawk is required to submit to the PSC a final accounting of the costs and
proceeds from the sale of its assets upon completion of the final sale. Niagara
Mohawk will begin recovery of the loss in 2003, over a period not to exceed the
average remaining life of the assets sold, estimated at 20 years. Niagara
Mohawk has earned an incentive as provided for in PowerChoice of $9.0 million
based on the asset sales concluded in 1999, which is reflected in income in 1999
and is recorded as an other regulatory asset in the Consolidated Balance Sheets.
An additional incentive is expected to be earned upon the completion of the
remaining assets sales of approximately $6.0 million. Niagara Mohawk will begin
recovery of this amount in 2001, over a period not to exceed 5 years.

Niagara Mohawk has also announced an agreement to sell its nuclear generation
assets. Niagara Mohawk estimates its net loss from the nuclear sale to be in
the range of $1,800 to $1,850 million. Niagara Mohawk has petitioned the PSC
for approval to defer this net loss for future recovery, which approval is a
condition of the closing of the sale of the nuclear assets. See Note 3. -
Nuclear Operations, for a complete discussion regarding this announced sale of
Niagara Mohawk's nuclear generation assets and its regulatory treatment.

POSTRETIREMENT BENEFITS OTHER THAN PENSIONS

The postretirement benefits other than pensions regulatory asset represent the
excess of such costs recognized in accordance with SFAS No. 106 over the amount
received in rates. In accordance with a PSC policy statement, postretirement
benefit costs other than pensions were phased into rates generally over a
five-year period and amounts deferred are being amortized and recovered over a
period of approximately 15 years.

UNAMORTIZED DEBT EXPENSE

The unamortized debt expense regulatory asset represents the costs to issue and
redeem certain long-term debt securities, which were retired prior to maturity.
These amounts are amortized as interest expense ratably over the lives of the
related issues in accordance with PSC directives.

OTHER

Included in the other regulatory asset is the accumulation of numerous
miscellaneous regulatory deferrals, including the deferral of nuclear outage
costs, uncollectible accounts receivable, nuclear decontamination and
decommissioning fund costs, and income earned on gas rate sharing mechanisms.

The EITF of the FASB reached a consensus on Issue No. 97-4 "Deregulation of the
Pricing of Electricity - Issues Related to the Application of SFAS No. 71 and
SFAS No. 101" in July 1997. EITF 97-4 does not require a company to earn a
return on regulatory assets that arise from a deregulating transition plan in
assessing the applicability of SFAS No. 71. Niagara Mohawk believes that the
regulated cash flows to be derived from prices it will charge for electric
service over the next ten years, including the Competitive Transition Charge
("CTC") assuming no unforeseen reduction in demand or bypass of the CTC or exit
fees, will be sufficient to recover the MRA regulatory asset and to provide
recovery of and a return on the remainder of its assets, as appropriate. In the
event Niagara Mohawk determines, as a result of lower than expected revenues
and/or higher than expected costs, that its net regulatory assets are not
probable of recovery, it can no longer apply the principles of SFAS No. 71 and
would be required to record an after-tax non-cash charge against income for any
remaining unamortized regulatory assets and liabilities. If Niagara Mohawk
could no longer apply SFAS No. 71, the resulting charge would be material to
Holdings and Niagara Mohawk's reported financial condition and results of
operations and adversely effect Niagara Mohawk's, and therefore, Holdings'
ability to pay dividends.

Under PowerChoice, Niagara Mohawk's remaining electric business (electric
transmission, distribution and nuclear business) will continue to be
rate-regulated on a cost-of-service basis and, accordingly, Niagara Mohawk
continues to apply SFAS No. 71 to these businesses. Also, Niagara Mohawk's IPP
contracts, including those restructured under the MRA, as well as the PPAs
entered into in connection with the generation divestiture, will continue to be
the obligations of the regulated business.



NOTE 3. NUCLEAR OPERATIONS

Niagara Mohawk is the owner and operator of the 613 MW Unit 1 and the operator
and a 41% co-owner of the 1,143 MW Unit 2. The remaining ownership interests
are Long Island Power Authority (LIPA) - 18%; NYSEG - 18%; Rochester Gas and
Electric Corporation (RG&E) - 14%; and Central Hudson - 9%. Unit 1 was placed
in commercial operation in 1969 and Unit 2 in 1988.

ANNOUNCED SALE: On June 24, 1999, Niagara Mohawk announced an agreement to sell
its nuclear assets to AmerGen Energy Company, LLC ("AmerGen"), a joint venture
of PECO Energy Company and British Energy, for approximately $135 million, which
is subject to price adjustments depending on the time of closing. Along with
the asset purchase agreement, Niagara Mohawk also signed PPAs with AmerGen to
purchase energy and capacity at negotiated prices. See Note 8 for a further
discussion of these PPAs under "Long term contracts for the purchase of electric
power."

New York State Electric and Gas Corporation is also a party to the agreement and
has agreed to sell its 18% share of Unit 2 to AmerGen. The sale to AmerGen is
subject to a previously existing agreement among the five co-owners of Unit 2
that gives the co-owners the right to match a third-party purchase offer made
for any share of the plant. On December 21, 1999, RG&E, a 14% co-owner,
submitted a notice stating it would match the AmerGen agreement.

As a condition of the sale transaction, Niagara Mohawk will pre-fund its nuclear
decommissioning trust funds (discussed below) at the closing to a predetermined
amount (which amount is contingent upon tax rulings and the closing date). The
trust funds will be transferred to the buyer at the closing, and the buyer will
assume full responsibility for the decommissioning of Unit 1 and its ownership
share of Unit 2. If the sale occurs on July 1, 2000, Niagara Mohawk estimates
that it will be required to make additional contributions to the decommissioning
trust funds of approximately $90 million.

At December 31, 1999, the net book value of Niagara Mohawk's nuclear generation
assets (including materials, supplies and nuclear fuel) was approximately $1.6
billion, excluding the reserve for decommissioning. In addition, Niagara Mohawk
has other nuclear-related assets of approximately $0.5 billion. These assets
include the decommissioning trusts and regulatory assets, primarily related to
the flow-through to customers of prior income tax benefits.

Because of the uncertainty as to whether the PSC will approve the sale of the
nuclear generating plants on terms acceptable to Niagara Mohawk, and the outcome
of other regulatory approvals, Niagara Mohawk has continued to utilize its best
estimate of cash flows based on a held-and-used (regulated) model for purposes
of assessing whether an asset impairment existed as of December 31, 1999. Under
this assumption the nuclear generating plants are not impaired.

If, and when, Niagara Mohawk concludes that its best estimate of future cash
flows is from the sale of the power plants, the impairment test will be
performed taking into consideration the expected cash flows from operations
until sale, expected cash proceeds from the sale of the assets, less amounts
required to pre-fund the nuclear decommissioning trust funds. In that event,
Niagara Mohawk estimates its net loss (stranded costs) from the nuclear sale
would be in the range of $1,800 to $1,850 million.

Niagara Mohawk has petitioned the PSC for approval to defer the net loss that
would be recognized on the sale for future recovery, which approval is a
condition of the closing of the sale of the nuclear assets. Accordingly,
Niagara Mohawk plans to record a regulatory asset for the amount of the
estimated net loss, as calculated pursuant to the assumptions and circumstances
described in the preceding paragraph. However, the ability to record the
regulatory asset is ultimately conditioned on an assessment by Niagara Mohawk
that the amounts are probable of future recovery in rates and that the rates
ultimately approved by the PSC can be charged to and collected from customers
without unanticipated reduction in demand.

The amount of the estimated net loss on the sale of the nuclear assets is
subject to change as a result of closing price adjustments, transaction costs
and the final amount needed to pre-fund the decommissioning trust funds. The
estimated range of loss excludes any accounting requirements relating to the
nuclear PPAs. Niagara Mohawk has proposed to recover the regulatory asset, plus
a return on the unamortized balance over a period not to exceed 15 years
beginning in 2000, with a significant portion of the recovery likely to occur in
years subsequent to the MRA regulatory asset amortization. Niagara Mohawk's
current rate structure includes recovery and a return on the nuclear assets.
Niagara Mohawk proposes to recover a return on and a return of stranded nuclear
costs within the rate structures contained in its PowerChoice agreement. This
sale is also contingent upon approval by, among others, the PSC, NRC, IRS, and
the SEC.

Niagara Mohawk originally requested PSC approval by December 1999 and has filed
an application with the NRC to transfer the licenses to AmerGen. It is unlikely
that any sale will close prior to the planned Unit 2 refueling and maintenance
outage scheduled to begin in March 2000. A delay in the sale through the
planned outage would result in an increase in the purchase price of Unit 2 as
specified in the agreement to reflect the estimated costs of the refueling and
maintenance outage. The sale price of Unit 1 decreases if the sale occurs after
the Unit 2 refueling and maintenance outage. Until the sale is closed, Niagara
Mohawk generally bears the risks associated with unexpected costs of the
refueling outage at Unit 2 and any unscheduled outages at both units, including
investigations and unexpected maintenance and capital costs. The purchase
agreement terminates if the sale has not occurred before September 1, 2000. In
the event that the sale of the nuclear assets does not occur, Niagara Mohawk
will continue to recover the costs to run the nuclear generation plants in its
PowerChoice rates. In addition, Niagara Mohawk would continue to participate in
the PSC regulatory proceeding regarding the future of nuclear assets in New York
State. On October 27, 1999, the FERC approved the sale of the transmission
assets connected to the nuclear plants to AmerGen. On January 26, 2000, the PSC
Staff had informed the ALJ and all parties, including Niagara Mohawk, that they
believed the terms of the proposed nuclear sale were not in the public interest.
The PSC Staff is continuing its discussions with AmerGen, as well as exploring
other options, including giving other interested parties the opportunity to put
forth competing proposals. Niagara Mohawk cannot predict the outcome of this
proceeding, but is committed to pursue the sale of Unit 1 and Unit 2.
Notwithstanding this commitment, because of the regulatory hurdles that must be
overcome, Niagara Mohawk does not believe that such a sale is any more likely to
occur than other possible scenarios, including the possible continued operation
of the plants by Niagara Mohawk for the remainder of the their useful lives.

Upon closing of the sale of the nuclear assets, Niagara Mohawk will continue to
be liable for all spent nuclear fuel fees associated with electricity generated
and sold and Unit 1 and Unit 2, prior to the closing. See "Nuclear Fuel
Disposal Cost" for a discussion of the Nuclear Waste Policy Act of 1982 and
Niagara Mohawk's determination of liability. This liability will remain with
Niagara Mohawk until the DOE provides disposal facilities. Niagara Mohawk also
retains liability for changes enacted prior to closing, if any, in the disposal
fees already paid to the DOE for fuel burned from 1983 through closing of the
sale or in the pre-1983 liability. Niagara Mohawk has recovered these costs in
rates in the past and believes that any increases in these costs would
ultimately be included in the rate process.

NUCLEAR PLANT DECOMMISSIONING: If the sale does not occur, Niagara Mohawk
estimates its site specific costs for decommissioning Unit 1 and its ownership
interest in Unit 2 at December 31, 1999 are as follows:




Unit 1 Unit 2

--------------
$ 312
==============



* Niagara Mohawk has not made a final decision on the timing of decommissioning
for Unit 1. Decommissioning could occur immediately after end of license
shutdown in 2009 or coincident with Unit 2 decommissioning which would
commence in 2026. The cost of decommissioning Unit 1 in January 2000
dollars is estimated to be $594 million for immediate dismantlement or $724
million for delayed dismantlement. Projected earnings from the
decommissioning fund are expected to approximate the cost impact of inflation
and continuing care under a delayed scenario. The final decision to
decommission Unit 1 immediately after shutdown or to delay will occur much
closer to the end of license shutdown date of 2009 so that Niagara Mohawk can
adequately evaluate the variables that could impact total costs. These
variables include but are not limited to the inflation projections, actual
earnings rate on the decommissioning fund, the uncertainty of the
availability of a low level waste disposal site and the DOE acceptance date
and rate of spent fuel disposal.

Niagara Mohawk estimates that by the time decommissioning is completed, the
above costs will ultimately amount to $1.0 billion (immediate dismantlement) or
$1.7 billion (delayed dismantlement) for Unit 1 and $0.9 billion for Niagara
Mohawk's share of Unit 2, using approximately 3.5% as an annual inflation
factor.

In addition to the costs mentioned above, Niagara Mohawk would expect to incur
post-shutdown costs for plant ramp down, insurance and property taxes. In 2000
dollars, these costs are expected to amount to $117 million (immediate
dismantlement) or $127 million (delayed dismantlement) for Unit 1 and $65
million for Niagara Mohawk's share of Unit 2. The amounts will escalate
to $193 million (immediate dismantlement) or $210 million (delayed
dismantlement) and $190 million for Unit 1 and Niagara Mohawk's share of
Unit 2, respectively, by the time decommissioning is expected to be completed.

NRC regulations require owners of nuclear power plants to place funds into an
external trust to provide for the cost of decommissioning radioactive portions
of nuclear facilities and establish minimum amounts that must be available in
such a trust at the time of decommissioning. The allowance for Unit 1 and
Niagara Mohawk's share of Unit 2 was approximately $28 million for the year
ended December 31, 1999. PowerChoice permits rate recovery for all radioactive
and non-radioactive cost components for both units, including post-shutdown
costs, based upon the amounts estimated in the 1995 site specific studies
described above, which are higher than the NRC minimum. The annual
decommissioning allowance (which includes funds to be placed into the external
trust plus internal reserves) for 2000 will increase to $43.3 million of which
$28 million is for radioactive components and $15.3 million is for non-
radioactive components. There is no assurance that the decommissioning
allowance recovered in rates will ultimately aggregate a sufficient amount to
decommission the units. Niagara Mohawk believes that if decommissioning costs
are higher than currently estimated, the costs would ultimately be included in
the rate process.

Decommissioning costs recovered in rates are reflected in "Accumulated
depreciation and amortization" on the balance sheet and amount to $353.1 million
and $315.5 million at December 31, 1999 and 1998, respectively for both units.
Additionally at December 31, 1999, the fair value of funds accumulated in
Niagara Mohawk's external trusts were $210.2 million for Unit 1 and $70.9
million for its share of Unit 2. The trusts are included in "Other Property and
Investments." Earnings on the external trust aggregated $45.3 million through
December 31, 1999, and because the earnings are available to fund
decommissioning, have also been included in "Accumulated depreciation and
amortization." For a further discussion on the earnings on the external trust,
see Note 9. Amounts recovered for non-radioactive dismantlement are accumulated
in an internal reserve fund, which has an accumulated balance of $65 million at
December 31, 1999.

NUCLEAR LIABILITY INSURANCE: The Atomic Energy Act of 1954, as amended,
requires the purchase of nuclear liability insurance from the Nuclear Insurance
Pools in amounts as determined by the NRC. At the present time, Niagara Mohawk
maintains the required $200 million of nuclear liability insurance.

With respect to a nuclear incident at a licensed reactor, the statutory limit
for the protection of the public under the Price-Anderson Amendments Act of
1988, which is in excess of the $200 million of nuclear liability insurance, is
currently $8.89 billion without the 5% surcharge discussed below. This limit
would be funded by assessments of up to $83.9 million for each of the 106
presently licensed nuclear reactors in the United States, payable at a rate not
to exceed $10 million per reactor, per year, per incident. Such assessments are
subject to periodic inflation indexing and to a 5% surcharge if funds prove
insufficient to pay claims. With the 5% surcharge included, the statutory limit
is $9.34 billion.

Niagara Mohawk's interest in Units 1 and 2 could expose it to a maximum
potential loss, for each accident, of $124.2 million (with 5% assessment)
through assessments of $14.1 million per year in the event of a serious nuclear
accident at its own or another licensed U.S. commercial nuclear reactor. The
amendments also provide, among other things, that insurance and indemnity will
cover precautionary evacuations, whether or not a nuclear incident actually
occurs.

This liability would transfer to the purchaser of the nuclear generation assets,
if the assets are used.

NUCLEAR PROPERTY INSURANCE: The Nine Mile Point Nuclear Site has $500 million
primary nuclear property insurance with the American Nuclear Insurers (ANI). In
addition, there is $2.25 billion in excess of the $500 million primary nuclear
insurance with Nuclear Electric Insurance Limited ("NEIL"). The total nuclear
property insurance is $2.75 billion. NEIL also provides insurance coverage
against the extra expense incurred in purchasing replacement power during
prolonged accidental outages. The insurance provides coverage for outages for
162 weeks, after a 12- week waiting period. NEIL insurance is subject to
retrospective premium adjustment under which Niagara Mohawk could be assessed up
to approximately $8.8 million per loss.

If the sale of the nuclear generation assets occurs, Niagara Mohawk will still
be liable for retrospective premium adjustments that are associated with NEIL
losses that occurred prior to the date of the sale for up to a period of six
years following the sale. As of December 31, 1999, Niagara Mohawk has not been
made aware of any material retrospective premium adjustments.

LOW LEVEL RADIOACTIVE WASTE: Niagara Mohawk currently uses the Barnwell, South
Carolina waste disposal facility for low level radioactive waste. However,
continued access to Barnwell is not assured, and Niagara Mohawk has implemented
a low level radioactive waste management program so that Unit 1 and Unit 2 are
prepared to properly handle interim on-site storage of low level radioactive
waste for at least a ten-year period.

Under the Federal Low Level Waste Policy Amendment Act of 1985, New York State
was required by January 1, 1993 to have arranged for the disposal of all low
level radioactive waste within the state or in the alternative, contracted for
the disposal at a facility outside the state. To date, New York State has made
no funding available to support siting for a disposal facility.

NUCLEAR FUEL DISPOSAL COST: In January 1983, the Nuclear Waste Policy Act of
1982 (the "Nuclear Waste Act") established a cost of $.001 per KWh of net
generation for current disposal of nuclear fuel and provides for a determination
of Niagara Mohawk's liability to the DOE for the disposal of nuclear fuel
irradiated prior to 1983. The Nuclear Waste Act also provides three payment
options for liquidating such liability and Niagara Mohawk has elected to delay
payment, with interest, until the year in which Niagara Mohawk initially plans
to ship irradiated fuel to an approved DOE disposal facility. Progress in
developing the DOE facility has been slow and it is anticipated that the DOE
facility will not be ready to accept deliveries until at least 2010. In July
1996, the United States Circuit Court of Appeals for the District of Columbia
ruled that the DOE had an obligation to accept spent fuel from the nuclear
industry by January 31, 1998 even though a permanent storage site would not be
ready by then. The DOE did not appeal this decision. On January 31, 1997,
Niagara Mohawk joined a number of other utilities, states, state agencies and
regulatory commissions in filing a suit in the U.S. Court of Appeals for the
District of Columbia against the DOE. The suit requested the court to suspend
the utilities payments into the Nuclear Waste Fund and to place future payments
into an escrow account until the DOE fulfills its obligation to accept spent
fuel. The DOE did not meet its January 31, 1998 deadline and indicated it was
not obligated to provide a financial remedy for delay. On November 14, 1997 the
United States Court of Appeals for the District of Columbia Circuit issued a
writ of mandamus precluding DOE from excusing its own delay on the grounds that
it has not yet prepared a permanent repository or interim storage facility. On
December 11, 1997, 27 utilities, including Niagara Mohawk, petitioned the DOE to
suspend their future payments to the Nuclear Waste Fund until the DOE begins
moving fuel from their plant sites. The petition further sought permission to
escrow payments to the waste fund beginning in February 1998. On January 12,
1998, the DOE denied the petition. In 1998, both the House and the U.S. Senate
passed legislation to reform the federal government's spent nuclear fuel
disposal policy. This legislation authorized DOE to construct an interim spent
fuel storage facility to accommodate acceptance of spent fuel beginning no later
than June 2003. Additionally, this legislation required the payment of one-time
fees by electric utilities for the disposal of fuel irradiated prior to 1983 to
be paid to the Nuclear Waste Fund no later than September 30, 2001. However,
this legislation was never sent to the President for approval. As of December
31, 1999, Niagara Mohawk has recorded a liability of $126.0 million in other
long-term debt for the disposal of nuclear fuel irradiated prior to 1983.

Niagara Mohawk has several alternatives under consideration to provide
additional spent fuel storage facilities, as necessary. Each alternative will
likely require NRC approval, may require other regulatory approvals and would
likely require incurring additional costs, which Niagara Mohawk has included in
its decommissioning estimates for both Unit 1 and its share of Unit 2. Niagara
Mohawk does not believe that the possible unavailability of the DOE disposal
facility until 2010 will inhibit operation of either Unit.

(b) On March 31, 1999, Niagara Mohawk distributed its ownership interest in
the stock of Opinac as a dividend to Holdings. As a result, the
accumulated other comprehensive income of Opinac of $25,186 million,
which is entirely made up of foreign currency translation adjustment,
is no longer included in Niagara Mohawk's "Accumulated Other Comprehensive
Income." (See Note 1)
(c) The fixed-adjustable rate preferred stock issued during 1999 has a $25
par value with a $50 liquidation preference.

The cumulative amount of unrealized gain on securities was $814 and the
additional minimum pension liability was $5,967 at December 31, 1999.



Niagara Mohawk has been reviewing its capital structure in light of its
scheduled debt reduction program, its divestiture of its electric generation and
the changing industry. As a result, Niagara Mohawk filed two petitions with the
PSC on July 1, 1999. The PSC approved the petitions on September 22, 1999 as
follows:

- - REFINANCE NIAGARA MOHAWK PREFERRED STOCK - The PSC approved Niagara Mohawk's
petition to issue up to $350 million in preferred stock to refinance
existing preferred stock outstanding through December 31, 2000. During
November 1999, Niagara Mohawk completed the sale of $150 million of
fixed-adjustable rate preferred stock (Series D) at a fixed rate of 6.9%
for the first five years. The 3 million shares of fixed-adjustable rate
preferred stock has a $25 par value with a $50 liquidation preference.
Niagara Mohawk used the proceeds from the sale to redeem its 9.5% series of
$25 par value optionally-redeemable preferred stock on December 31, 1999.

- - PURCHASE OF HOLDINGS' COMMON STOCK - The PSC approved Niagara Mohawk's
petition to purchase up to $800 million of Holdings' common stock. Holdings'
Board of Directors has approved a program to repurchase 20 million shares
through December 31, 2001.

During the third quarter of 1999, Niagara Mohawk entered into two agreements,
which expire in less than one year, whereby two agents would purchase up to 9
million shares of Holdings' common stock on Niagara Mohawk's behalf. At any
time prior to the expiration of these agreements, Niagara Mohawk can
repurchase the common stock from the agents and is required to reimburse
these agents (in stock and/or cash) for the costs they incurred to buy the
stock plus a carrying charge. The two agents have incurred a total of
approximately $140.3 million to purchase the 9 million shares. During
December 1999, Niagara Mohawk purchased 4 million shares from one of the
agents for approximately $64.3 million, including fees paid to the agent.
The remaining 5 million shares repurchased by the other agent, but not yet
paid for by Niagara Mohawk (with the exception of $1.4 million in carrying
charges) remain in the number of shares outstanding in computing Holdings'
earnings per share.

During the fourth quarter of 1999, Niagara Mohawk repurchased an additional 6
million shares of Holdings' common stock on the open market for approximately
$91.5 million, including fees.

Niagara Mohawk's long-term debt increased significantly upon the closing of the
MRA on June 30, 1998. The MRA was largely financed through the Senior Notes.
The Senior Notes are unsecured obligations of Niagara Mohawk and rank pari passu
in right of payment to its First Mortgage Bonds, the senior bank financing and
unsecured medium term notes.

Niagara Mohawk is obligated to use 85% of the net proceeds of the sales of the
generation assets to reduce its senior debt outstanding within 180 days after
the receipt of such proceeds. To date, Niagara Mohawk has received $860 million
on the sale of its two coal-fired generation plants, its hydro electric
generation plants, and its oil and gas-fired plant in Oswego. During 1999
Niagara Mohawk redeemed approximately $1.1 billion in debt using the proceeds
from the assets sales and from improved cash flow. See Notes 2 and 3 for a
discussion of the status of the remaining generation asset sales.

Several series of First Mortgage Bonds and Promissory Notes were issued to
secure a like amount of tax-exempt revenue bonds issued by NYSERDA.
Approximately $414 million of such securities bear interest at a daily
adjustable interest rate (with an option to convert to other rates, including a
fixed interest rate which would require Niagara Mohawk to issue First Mortgage
Bonds to secure the debt) which averaged 3.23% for 1999 and 3.39% for 1998 and
are supported by bank direct pay letters of credit. Pursuant to agreements
between NYSERDA and Niagara Mohawk, proceeds from such issues were used for the
purpose of financing the construction of certain pollution control facilities at
Niagara Mohawk's generation facilities or to refund outstanding tax-exempt bonds
and notes (see Note 5).

Other long-term debt in 1999 consists of obligations under capital leases of
approximately $22.1 million, a liability to the DOE for nuclear fuel disposal of
approximately $126.0 million and a liability for IPP contract terminations not
related to the MRA of approximately $38.8 million. The aggregate maturities of
long-term debt for the five years subsequent to December 31, 1999, excluding
capital leases, in millions, are approximately $610.5, $624.2, $544.0, $610.7
and $232.4, respectively. A reduction in debt that will occur from applying
proceeds from additional generation asset sales may impact the schedule of
maturities of long-term debt.

EARLY EXTINGUISHMENT OF DEBT

During 1999, Niagara Mohawk redeemed approximately $822 million in long-term
debt prior to its scheduled maturity. Holdings and Niagara Mohawk charged to
earnings, as an extraordinary item approximately $23.8 million, after tax, for
redemption premiums incurred, and unamortized debt expense and issuance costs.
This extraordinary item had a 13 cents per share, after tax effect on Holdings'
1999 earnings per share.



NOTE 5. BANK CREDIT ARRANGEMENTS

Niagara Mohawk has an $804 million senior bank financing with a bank group
consisting of a $255 million term loan facility, a $125 million revolving credit
facility and $424 million for letters of credit. The letter of credit facility
provides credit support for the adjustable rate pollution control revenue bonds
issued through the NYSERDA, discussed in Note 4. As of December 31, 1999, the
amount outstanding under the senior bank financing was $529 million, consisting
of $105 million under the term loan facility and $424 million of letters of
credit, leaving Niagara Mohawk with $275 million of borrowing capability under
the financing. The senior bank facility term expires on June 1, 2000. As a
result, the amount outstanding on this facility at December 31, 1999, $105
million, is shown as a current liability on both Holdings and Niagara Mohawk's
balance sheets. Niagara Mohawk is currently negotiating a new financing
arrangement with a bank group, and believes as a minimum it will be able to
obtain $424 million for letters of credit prior to the expiration of the senior
bank facility on June 1, 2000. The interest rate applicable to the facility is
variable based on certain rate options available under the agreement and
currently approximates 6.625% (but capped at 15%).

Opinac had an agreement with a bank providing for letters of credit totaling up
to $25 million, which in January 2000 was replaced by a $50 million bank
facility secured by certain assets of Opinac. The facility provides for letters
of credit and a $10 million line of credit. The facility expires September 30,
2000 and as of January 31, 2000, supports approximately $20 million in letters
of credit. Opinac is working to extend the facility beyond September 30, 2000.

Holdings and Niagara Mohawk did not have any short-term debt outstanding at
December 31, 1999 and 1998.

In December 1998, Niagara Mohawk received a ruling from the IRS to the effect
that the amount of cash and the value of common stock that was paid to the
terminated IPP Parties was deductible in 1998 and generated a substantial net
operating loss for federal income tax purposes, such that Niagara Mohawk did not
pay federal income taxes for 1998. Further, Niagara Mohawk has carried back
unused NOL carryforward to the years 1996 and 1997, and also for the years 1988
through 1990, which resulted in a tax refund of $135 million that were received
in January 1999. Holdings anticipates that it will be able to utilize the
remaining $3.3 billion NOL carryforward prior to its expiration date in 2019.
The amount of the NOL carryforward as of December 31, 1999 is $2.6 billion.
Holdings' ability to utilize the NOL carryforward generated, as a result of the
MRA could be limited under the rules of section 382 of the Internal Revenue Code
if certain changes in Holdings' common stock ownership were to occur in the
future.



NOTE 7. PENSION AND OTHER RETIREMENT PLANS

Niagara Mohawk and its affiliates have a non-contributory defined benefit
pension plan covering substantially all employees, which was amended during 1998
to include a cash balance benefit in which the participant has an account to
which amounts are credited based on qualifying compensation and with interest
determined annually based on average annual 30-year Treasury bond yield. The
majority of the costs and benefits associated with this plan are attributable to
Niagara Mohawk employees. Supplemental non-qualified, non-contributory
executive retirement programs provide additional defined pension benefits for
certain officers. In addition, Niagara Mohawk and its affiliates provide
certain contributory health care and life insurance benefits for active and
retired employees and dependents.

The changes in benefit obligations, plan assets and plan funded status for these
pension and other retirement plans as of, and for the year ended December 31,
are summarized as follows:

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



In 1999, Niagara Mohawk experienced a net curtailment/settlement gain of $35.3
million due to the employee transfers associated with the sale of the hydro and
fossil generating plants and normal terminations electing lump sum pension
benefits distributions under the cash balance option and receiving
postemployment medical and life insurance benefits. After a portion of the gain
was allocated to the co-tenants, $9.4 million of the net gain was included in
the deferred loss on the sale of the assets; the remaining $23.6 was deferred as
an Other Regulatory Liability as required by PSC regulations.

The non-qualified executive pension plan has no plan assets due to the nature of
the plan, and therefore, has an accumulated benefit obligation in excess of plan
assets of $12.4 million and $8.8 million at December 31, 1999 and 1998,
respectively.

The following table summarizes the components of the net annual benefit costs.

are vested, payment is probable and the amount of the benefits can be reasonably
estimated. At December 31, 1999 and 1998, Holdings' postemployment benefit
obligation is approximately $15.7 million and $15.3 million, respectively.



NOTE 8. COMMITMENTS AND CONTINGENCIES

LONG-TERM CONTRACTS FOR THE PURCHASE OF ELECTRIC POWER: Niagara Mohawk has
several types of long-term contracts for the purchase of electric power.
Niagara Mohawk's commitments under these long-term contracts, as of January 1,
2000, excluding its commitments with NYPA, which are shown separately, are
summarized in the table below. Following the table are descriptions of the
different types of these long-term contracts. For a detailed discussion of the
financial swap agreements that Niagara Mohawk has entered into as part of the
MRA and the sale of its generation assets (the sale of the Huntley and Dunkirk
coal-fired generation plants and the announced sale of the Albany oil and
gas-fired generation plant) which are not included in the table below, see Note
9.

*** Does not include puts (see below)



PURPA Contracts
- ---------------

Under the requirements of PURPA, Niagara Mohawk is required to purchase power
generated by IPPs, as defined therein. Niagara Mohawk has 112 PPAs with 120
IPP facilities, amounting to approximately 1,000 MW of capacity at December 31,
1999. All of this capacity amount is considered firm and excludes PPAs that
provide energy only. The table above includes the estimated payments for fixed
costs (capacity) and variable costs (capacity, energy and related taxes) that
Niagara Mohawk estimates it will be obligated to make under these 112 IPP
contracts, excluding the financial obligation under the swap contracts. The
payments to the IPPs are subject to the tested capacity and availability of the
facilities, scheduling and price escalation. These payments have been
significantly reduced by the consummation of the MRA and additional IPP buyouts
made in 1999. See Note 2 "IPP Buyout Costs" for a further discussion of the
additional IPP buyouts made in 1999.

Fixed capacity costs (in the table above) relate to three contracts as follows:

1) a contract with an IPP that was a party to the MRA,
2) a contract for the sale of the Oswego generation assets as discussed further
below, and
3) the contract for the sale of the hydroelectric generation assets as
discussed further below.

With respect to the IPP contract, Niagara Mohawk is required to
make capacity payments, including payments when the facility is not operating
but available for service. The terms of this contract allows Niagara Mohawk to
schedule energy deliveries and then pay for the energy delivered. Contracts
relating to the remaining IPP facilities in service at December 31, 1999,
require Niagara Mohawk to pay only when energy is delivered, except when Niagara
Mohawk decides that it would be better to pay a particular project a reduced
payment to have the project reduce its high priced energy deliveries. Niagara
Mohawk paid approximately $435 million, $785 million and $1,106 million in 1999,
1998 and 1997 for 6,765,000 MWh, 9,700,000 MWh and 13,500,000 MWh, respectively,
of electric power under all IPP contracts.

Fossil/Hydro Contracts
- ----------------------
As part of the sale of Niagara Mohawk's fossil and hydro generation assets,
Niagara Mohawk entered into PPAs with the buyers of these assets for the
purchase of capacity and energy as discussed in more detail below. The table
above includes the estimated payments for variable costs and quantities
(capacity and energy) associated with the PPAs that Niagara Mohawk estimates it
will make under these contracts. Niagara Mohawk paid approximately $123.7
million in 1999 for 2,409 MW of capacity and 3,490,000 MWh of electric power
under these PPAs. The table above does not include the estimated payments for
the PPAs entered into with the buyers of the Albany Steam Station and the
nuclear generation assets, since Niagara Mohawk has not closed on these asset
sales.

The hydro PPA calls for the purchase of all energy and capacity through
September 2001 at prices that approximate forecasted future market prices.
Niagara Mohawk anticipates that the energy and capacity to be purchased under
the hydro PPA to be at quantities approximating historical generation levels,
subject to the effects of water flow availability. The Oswego PPA is primarily
a contract for capacity with a nominal amount of energy at prices above
forecasted future market prices.

Nuclear Contracts
- -----------------
As part of the agreement with AmerGen to sell its nuclear generation assets,
Niagara Mohawk would enter into PPAs to purchase energy and capacity at
negotiated prices. The negotiated prices are expected to be, on average, above
projected market prices during the term of the PPAs. Niagara Mohawk would pay
only for delivered output from the units. The terms of the PPAs would be for
five years from Unit 1 and three years from Unit 2. Upon the expiration of the
PPA for Unit 2, there would be a financial sharing agreement whereby Niagara
Mohawk would be entitled to future payments from the purchaser over a ten-year
period if electric energy market prices exceed certain amounts during the
ten-year sharing period. Niagara Mohawk has proposed to the PSC that any future
payments received under the financial sharing agreement will serve to reduce the
unamortized regulatory asset recorded as a result of the sale of the nuclear
assets. See Note 3. - Nuclear Operations, for a complete discussion of the
proposed sale of the nuclear generation assets.

PUT Contracts
- -------------

As a part of the MRA, Niagara Mohawk signed put agreements with approximately
one-third of the IPP Parties whereby the IPP Parties have an option to put the
physical delivery of energy to Niagara Mohawk at market prices. These put
agreements will be in effect until the NYISO meets certain volume and capacity
conditions for a consecutive six-month period. If the NYISO does not meet the
defined volume and capacity transactions that are outlined in the put
agreements, then the put agreements are in effect until June 2008. Since
Niagara Mohawk cannot predict if and when the NYISO will meet the volume and
capacity conditions, the cost and quantity of energy associated with the put
agreements have not been included in the table above. During 1999, Niagara
Mohawk paid $75.9 million to the IPP Parties for 2,782,678 MWh of electric
power received as part of these put agreements. If the put agreements remain
in effect, Niagara Mohawk expects to pay approximately $77.1 million to $91.3
million for 4,031,000 MWh to 4,093,000 MWh of electric power in each of the
years 2000 to 2004.

While the PPAs for the generation asset sales, which were entered into as an
integral part of the generation sales, are above market, they are designed to
help Niagara Mohawk meet the objectives of rate reduction and price cap
commitments as well as meet expected demand as the "provider of last resort" as
outlined in the PowerChoice agreement.

At January 1, 2000, Niagara Mohawk had long-term contracts to purchase electric
power from the following generation facilities owned by NYPA:

1,325 $ 37,092,000
=========== ==============



The purchase capacities shown above are based on the contracts currently in
effect. The estimated annual capacity costs are subject to price escalation and
are exclusive of applicable energy charges. The total cost of purchases under
these contracts, plus other miscellaneous NYPA purchases, was approximately, in
millions, $112.4, $93.1 and $91.0 for the years 1999, 1998 and 1997,
respectively. Niagara Mohawk continues to have a contract with NYPA's
Fitzpatrick nuclear facility to purchase for resale up to 46 MW of power for
NYPA's economic development customers.

In addition to the contractual commitments described above, Niagara Mohawk
entered into a four-year contract, expiring in June 2003, that gives it the
option to buy additional power at market prices from the Huntley coal-fired
generation plant, now owned by NRG. If Niagara Mohawk needs any additional
energy to meet its load it can purchase the electricity from other IPPs, other
utilities, other energy merchants or through the NYISO at market prices.

GAS SUPPLY, STORAGE AND PIPELINE COMMITMENTS: In connection with its regulated
gas business, Niagara Mohawk has long-term commitments with a variety of
suppliers and pipelines to purchase gas commodity, provide gas storage
capability and transport gas commodity on interstate gas pipelines.

The table below sets forth Niagara Mohawk's estimated commitments at December
31, 1999, for the next five years, and thereafter.




(In thousands of dollars)
Gas Storage/
Year Gas Supply Pipeline
- ---------- -------------------- ---------

2000 . . . $ 55,175 $ 73,039
2001 . . . 52,538 66,203
2002 . . . 39,445 33,067
2003 . . . 39,445 11,535
2004 . . . 39,445 11,535
Thereafter 72,305 45,237



With respect to firm gas supply commitments, the amounts are based upon volumes
specified in the contracts giving consideration for the minimum take provisions.
Commodity prices are based on New York Mercantile Exchange quotes and
reservation charges, when applicable. Storage and pipeline capacity
commitments' amounts are based upon volumes specified in the contracts, and
represent demand charges priced at current filed tariffs. At December 31, 1999,
Niagara Mohawk's firm gas supply commitments extend through October 2006, while
the gas storage and transportation commitments extend through October 2012.

Gas Multi-Year Rate and Restructuring Proposal
- ----------------------------------------------

Niagara Mohawk filed a three-year gas rate and restructuring proposal on March
11, 1999 in anticipation of the expiration of its 1996 three-year gas rate
settlement agreement, which expired on November 1, 1999. Niagara Mohawk is
currently negotiating with the PS and other parties, but has not reached a
final agreement. However, on October 15, 1999 and January 12, 2000, the PSC
approved an interim arrangement that freezes delivery rates at current levels,
subject to refund if the permanent rates are lower and allows the pass through
to customers the benefits of lowered pipeline costs. In addition, the interim
arrangement minimizes Niagara Mohawk's exposure to stranded costs. The interim
agreement also included provisions for the implementation of both unbundled gas
rates and a return to a full gas cost collection mechanism (gas adjustment
clause "GAC") effective November 1, 1999. In addition, Niagara Mohawk is
allowed to recover all commodity costs along with fixed capacity costs for
capacity actually used to serve customers. It also provides that, pending
resolution of the issue in that case, costs for capacity upstream of CNG that
are not actually required for sales customer demands or offset by assignment and
secondary market release (stranded capacity costs) are not recoverable beginning
November 1, 1999. However, the potential for stranded costs are not considered
material to Niagara Mohawk's results of operations or financial condition. The
exposure may increase in the future as additional customers select alternative
suppliers. Niagara Mohawk is continuing to work with the PSC and other
interested parties to reach a final settlement, but it cannot predict the
timing or outcome of such a settlement.

Future of the Natural Gas Industry
- ----------------------------------
In November 1998, the PSC issued its Policy Statement concerning the Future of
the Natural Gas Industry in New York State and Order Terminating Capacity
Assignment ("PSC Policy Statement"). The PSC envisions a transitional time
frame of three to seven years for local gas distribution companies ("LDC") to
exit the business of purchasing natural gas (the "merchant" function). The PSC
established a process comprising three basic elements, to be pursued in parallel
in the exiting of the merchant function:

1. Addressing the issues involved in the exiting of the merchant function on
a utility-by-utility basis as part of the LDCs individual rate plans;

2. Collaboration among staff, LDCs, marketers, pipelines and other
stakeholders of generic issues such as operational and reliability issues,
protocols and information systems requiring a status report by April 1,
1999; and

3. Coordination of issues faced by electric utilities, including provider of
last resort issues and a plan to allow competition in other areas, such as
metering, billing and information services.

In December 1998, Niagara Mohawk notified the PSC that its specific operational
and reliability requirements continue to warrant certain mandatory capacity
assignment and inclusion of capacity costs in transportation rates after April
1, 1999. Niagara Mohawk will continue to assign CNG capacity until a final
determination is reached in the current rate and restructuring case. The PSC
noted in its PSC Policy Statement that it will provide LDCs with a reasonable
opportunity to recover these strandable costs if they can demonstrate compliance
with the PSC's directives to minimize such costs.

As a result of the collaborative process established in the PSC Policy
Statement, on August 19, 1999, the PSC issued an order requiring that marketers
serving firm customers have firm, primary delivery point capacity for the five
winter months of November through March, but allowed an alternative for
marketers, only for the 1999 - 2000 heating season, to have firm secondary
delivery point capacity and to pay the LDC a standby charge to provide backup
service. LDCs that implemented this Order would be presumed to have met the
PSC's directive to minimize their stranded costs.

Niagara Mohawk believes that it has taken numerous actions to reduce its
capacity obligations and its potential stranded costs, but is unable to predict
the outcome of this matter. Niagara Mohawk has addressed the issues from the
PSC Policy Statement in its three-year gas rate and restructuring proposal filed
on March 11, 1999 and as noted above, Niagara Mohawk is currently working with
the PSC and other interested parties to reach a final settlement.

SALE OF CUSTOMER RECEIVABLES: Niagara Mohawk has established a single-purpose,
financing subsidiary, NM Receivables LLC ("NMR"), whose business consists of the
purchase and resale of an undivided interest in a designated pool of Niagara
Mohawk customer receivables, including accrued unbilled revenues. For
receivables sold, Niagara Mohawk has retained collection and administrative
responsibilities as agent for the purchaser. As collections reduce previously
sold undivided interests, new receivables are customarily sold. NMR has its own
separate creditors which, upon liquidation of NMR, will be entitled to be
satisfied out of its assets prior to any value becoming available to Niagara
Mohawk. The sale of receivables are in fee simple for a reasonably equivalent
value and are not secured loans. Some receivables have been contributed in the
form of a capital contribution to NMR in fee simple for reasonably equivalent
value, and all receivables transferred to NMR are assets owned by NMR in fee
simple and are not available to pay Niagara Mohawk's creditors.

At December 31, 1999 and 1998, $215.1 million and $150 million, respectively, of
receivables had been sold by NMR to a third party. The undivided interest in
the designated pool of receivables was sold with limited recourse. The
agreement provides for a formula based loss reserve pursuant to which
additional customer receivables are assigned to the purchaser to protect against
bad debts. At December 31, 1999, the amount of additional receivables assigned
to the purchaser, as a loss reserve, was approximately $83.2 million.

To the extent actual loss experience of the pool receivables exceeds the loss
reserve, the purchaser absorbs the excess. Concentrations of credit risk to the
purchaser with respect to accounts receivable are limited due to Niagara
Mohawk's large, diverse customer base within its service territory. Niagara
Mohawk generally does not require collateral, i.e., customer deposits.

In the fourth quarter of 1999, NMR was not in compliance with a certain
statistical ratio relating to the pool of receivables sold. The purchaser has
granted a waiver for this period. While NMR is working to return to compliance
with this ratio, it is possible a non-compliance condition could continue to
exist. NMR is unable to predict whether further waivers would be granted.

CUSTOMER SERVICE SYSTEM: Niagara Mohawk implemented a new customer service
system in mid-February 1999, which experienced transition issues in customer
satisfaction, incremental costs and PSC scrutiny. The PSC has begun an inquiry
into the development and implementation costs of CSS, as well as Niagara
Mohawk's exposure to operational issues during transition. Niagara Mohawk is
unable to predict the outcome or financial consequences, if any, of the PSC
inquiry.

ENVIRONMENTAL CONTINGENCIES: The public utility industry typically utilizes
and/or generates in its operations a broad range of hazardous and potentially
hazardous wastes and by-products. Niagara Mohawk believes it is handling
identified wastes and by-products in a manner consistent with federal, state and
local requirements and has implemented an environmental audit program to
identify any potential areas of concern and aid in compliance with such
requirements. Niagara Mohawk is also currently conducting a program to
investigate and remediate, as necessary to meet current environmental standards,
certain properties associated with former gas manufacturing and other properties
which Niagara Mohawk has learned may be contaminated with industrial waste, as
well as investigating identified industrial waste sites as to which it may be
determined that Niagara Mohawk has contributed. Niagara Mohawk has also been
advised that various federal, state or local agencies believe certain properties
require investigation and has prioritized the sites based on available
information in order to enhance the management of investigation and remediation,
if necessary.

Niagara Mohawk is currently aware of 163 sites with which it may be associated,
including 86 which are Niagara Mohawk-owned. With respect to non-owned sites,
Niagara Mohawk may be required to contribute some proportionate share of
remedial costs. Although one party can, as a matter of law, be held liable for
all of the remedial costs at a site, regardless of fault, in practice costs are
usually allocated among PRPs. Niagara Mohawk has denied any responsibility at
certain of these PRP sites and is contesting liability accordingly.

Investigations at each of the Niagara Mohawk-owned sites are designed to (1)
determine if environmental contamination problems exist, (2) if necessary,
determine the appropriate remedial actions and (3) where appropriate, identify
other parties who should bear some or all of the cost of remediation. Legal
action against such other parties will be initiated where appropriate. After
site investigations are completed, Niagara Mohawk expects to determine
site-specific remedial actions and to estimate the attendant costs for
restoration. However, since investigations are ongoing for most sites, the
estimated cost of remedial action is subject to change.

Estimates of the cost of remediation and post-remedial monitoring are based upon
a variety of factors, including identified or potential contaminants; location,
size and use of the site; proximity to sensitive resources; status of regulatory
investigation and knowledge of activities at similarly situated sites.
Additionally, Niagara Mohawk's estimating process includes an initiative where
these factors are developed and reviewed using direct input and support obtained
from the DEC. Actual Niagara Mohawk expenditures are dependent upon the total
cost of investigation and remediation and the ultimate determination of Niagara
Mohawk's share of responsibility for such costs, as well as the financial
viability of other identified responsible parties since clean-up obligations are
joint and several. Niagara Mohawk has denied any responsibility at certain of
these PRP sites and is contesting liability accordingly.

As a consequence of site characterizations and assessments completed to date and
negotiations with PRPs, Niagara Mohawk has accrued a liability in the amount of
$240 million and $220 million, which is reflected in both Niagara Mohawk's and
Holdings' Consolidated Balance Sheets at December 31, 1999 and 1998,
respectively. The potential high end of the range is presently estimated at
approximately $480 million, including approximately $245 million in the unlikely
event Niagara Mohawk is required to assume 100% responsibility at non-owned
sites. Niagara Mohawk increased its environmental liability $20 million in 1999
as compared to 1998 primarily as a result of the availability of information on
certain sites resulting from progress made on feasibility studies. The
probabilistic method was used to determine the amount to be accrued for 24 of
Niagara Mohawk's largest sites. The amount accrued for Niagara Mohawk's
remaining sites is determined through feasibility studies or engineering
estimates, Niagara Mohawk's estimated share of a PRP allocation or where no
better estimate is available, the low end of a range of possible outcomes is
used. In addition, Niagara Mohawk has recorded a regulatory asset representing
the remediation obligations to be recovered from ratepayers. PowerChoice and
the gas settlements provide for the continued application of deferral accounting
for expense recognition resulting from this effort.

Niagara Mohawk recently informed the DEC in response to an October 1999 request
for information, of 24 additional former manufactured gas plant sites that it
may be associated with, including 2 sites that are currently owned by Niagara
Mohawk. Niagara Mohawk is unable to predict what further action the DEC may
take with respect to these sites.

In November 1999, Niagara Mohawk submitted a revised feasibility study to the
DEC, which included the land-based portions of Niagara Mohawk's Harbor Point
site and five surrounding non-owned sites. The study indicates a range of
viable remedial approaches and associated cost estimates and recommends a
selected remedial alternative. This range consists of a high end of $70
million, with an expected value calculation of $49 million, which is included in
the amounts accrued at December 31, 1999. The surface water-based portions of
Niagara Mohawk's Harbor Point site are subject to continuing feasibility study
evaluations and review by the DEC. Niagara Mohawk currently estimates the range
of costs for remediation of the surface water bodies to consist of a high end of
$18 million, with an expected value of $11 million. The ranges for the
land-based and the surface water bodies portions represent the total estimated
costs to remediate the properties and does not consider contributions from other
PRPs, the amount of which Niagara Mohawk is unable to estimate.

In May 1995, Niagara Mohawk filed a complaint pursuant to applicable Federal and
New York State law, in the U.S. District Court for the Northern District of New
York against several defendants seeking recovery of past and future costs
associated with the investigation and remediation of the Harbor Point and
surrounding sites. The New York State Attorney General moved to dismiss Niagara
Mohawk's claims against the state of New York, the New York State Department of
Transportation and the Thruway Authority and Canal Corporation under the
Comprehensive Environmental Response, Compensation and Liability Act. Niagara
Mohawk opposed this motion. On April 3, 1998, the Court denied the New York
State Attorney General's motion as it pertains to the Thruway Authority and
Canal Corporation, and granted the motion relative to the state of New York and
the Department of Transportation. The case management order, as amended by the
Court, establishes February 29, 2000 as the trial ready date. As a result,
Niagara Mohawk cannot predict the outcome of the pending litigation against the
defendants or the allocation of Niagara Mohawk's share of the costs to remediate
the Harbor Point and surrounding sites.

CONSTRUCTION PROGRAM: Niagara Mohawk is committed to an ongoing construction
program to assure transmission and delivery of its electric and gas services.
Niagara Mohawk presently estimates that the construction program for the years
2000 through 2002 will require approximately $678 million, excluding AFC and
nuclear fuel. For the years 2000 through 2002, the estimates, in millions, are
$219, $229, and $230, respectively, which includes amounts relating to Niagara
Mohawk's nuclear assets through June 2000, its Albany plant through March 2000,
and Niagara Mohawk's 25 percent ownership share in the Roseton plant through
December 2000. If the nuclear sale does not occur, Niagara Mohawk estimates it
will incur expenditures for construction and nuclear fuel of $69 million for
2000 and $32 million and $67 million for 2001 and 2002, respectively. Any delay
in the timing or outcome of these remaining generation asset sales will effect
Niagara Mohawk's capital expenditure requirements.



NOTE 9. FAIR VALUE OF FINANCIAL AND DERIVATIVE FINANCIAL INSTRUMENTS

The discussion that follows covers Holdings and Niagara Mohawk and its
subsidiaries. When necessary, specific reference is made to the subsidiary
company. The figures for Holdings and Niagara Mohawk differ only in the Cash
and temporary cash investments. All other figures shown for Holdings are the
same for Niagara Mohawk.

The following methods and assumptions were used to estimate the fair value of
each class of financial instruments:

CASH AND TEMPORARY CASH INVESTMENTS: The carrying amount approximates fair
value because of the short maturity of the financial instruments.

LONG-TERM DEBT AND MANDATORILY REDEEMABLE PREFERRED STOCK: The fair value of
fixed rate long-term debt and redeemable preferred stock is estimated using
quoted market prices where available or discounting remaining cash flows at
Niagara Mohawk's incremental borrowing rate. The carrying value of NYSERDA
bonds and other long-term debt are considered to approximate fair value.

DERIVATIVE FINANCIAL INSTRUMENTS: The fair value of futures and forward
contracts are determined using quoted market prices and broker quotes. (See
Note 8 for a discussion of the financial sharing agreement that Niagara Mohawk
has entered into in connection with the announced sale of the nuclear generation
assets.)

SWAP CONTRACTS: Niagara Mohawk has two different types of swap contracts; the
IPP indexed swap contracts and the swap contracts resulting from the sale of
Niagara Mohawk's Huntley and Dunkirk coal-fired generation plants. The terms of
the two types of contracts are as follows:

- - IPP INDEXED SWAP CONTRACTS - Niagara Mohawk, as part of the MRA, entered
into restated contracts with eight IPPs. The contracts have a term of ten
years and are structured as indexed swap contracts where Niagara Mohawk
receives or makes payments to the eight IPPs based upon the differential
between the contract price and a market reference price for electricity.
Niagara Mohawk has recorded the liability for these contractual obligation
and recorded a corresponding regulatory asset since payments under these
restated contracts are authorized and are currently being recovered under
PowerChoice. The amount of this liability and regulatory asset will
fluctuate as estimates of future market and contract prices change over the
term of the contracts, and will decrease over the life of the contract as
notional quantities are settled.

The contract prices are fixed for the first two years changing to an indexed
pricing formula primarily related to gas prices, thereafter. Contract
quantities are fixed for each year of the full ten-year term of the contracts
and average 4.1 million MWh. The indexed pricing structure ensures that the
price paid for energy and capacity will fluctuate relative to the underlying
market cost of gas and general indices of inflation.

- - HUNTLEY AND DUNKIRK GENERATING STATION SWAP CONTRACTS - As part of the
transaction to sell the Huntley and Dunkirk coal-fired generation plants,
Niagara Mohawk entered into PPAs to purchase energy and capacity from the
buyer, NRG Energy, Inc. ("NRG"). Niagara Mohawk was required to purchase a
portion of the energy generated by the two coal-fired plants; however, it had
call options to purchase additional energy if needed. The aggregate energy
and capacity costs in the PPAs were above forecasted future market prices.
The PPAs converted to financial swaps ("swaps") on December 1, 1999 and have
the same economic terms as the energy contracts, with no physical delivery o
energy.

The agreements expire in June of 2003. As of December 31, 1999, Niagara
Mohawk has recorded a $56.4 million swap contract liability for the present
value of the difference between the contract energy prices and projected
market prices and has recorded a corresponding swap contract regulatory
asset. The asset and liability will be amortized over the remaining term of
the swaps as nominal energy quantities are settled and may be adjusted as
periodic reassessments are made of future energy prices. These amounts are
included with the swap contract asset and liability.

The agreements to purchase capacity and energy began at the sale date of the
assets (June 1999). Base quantities were set by the contract with a call
option on additional amounts. The contracts converted to financial swaps at
December 1, 1999 triggered by the ISO implementation. Contract quantities
average 2.9 million MWh annually. These agreements expire in June 2003.

In connection with the pending sale of the Albany plant, Niagara Mohawk has
entered into a contract with the new owner that is intended to compensate PSEG
in the near term for the costs of running the plant. This contract will be
recorded as a financial agreement at the time of the closing on the sale. The
contract is a financial agreement with an exchange of payments that are based on
the market price of energy and expires on September 30, 2003. No actual energy
will be delivered to Niagara Mohawk, but a quantity of energy, referred to as
the call amount, is used to calculate the payment. The call amount is capped
each year and totals 1,300 GWh for the life of the contract. The contract is a
derivative instrument. Each month Niagara Mohawk will pay PSEG a fixed monthly
charge plus the call amount times a contract price. The contract price
approximates the cost of fuel for the plant and will fluctuate as fuel prices
change. PSEG will pay Niagara Mohawk the same call amount times the current
market price for energy. This market price will be determined by the NYISO.
Niagara Mohawk has the sole option, within certain limits stated in the
contract, to decide what the call amount will be. This combination of a swap
with one party having an option is called a swaption. If the market price is
expected to be higher than the contract price, Niagara Mohawk would likely
exercise the option, elect a call amount, and PSEG will make a swap payment to
Niagara Mohawk. If the market price is expected to be below the contract price,
Niagara Mohawk would not likely choose to name a call amount, in which case
Niagara Mohawk would only be required to make the fixed monthly payment. For
Niagara Mohawk, this contract will serve as a hedge against rising energy
prices. Niagara Mohawk expects to account for this contract as a hedge of
future purchase commitments upon the closing of the sale, expected to occur in
the first quarter of 2000. The costs associated with the Albany contract are
recoverable under Niagara Mohawk's PowerChoice rates.

At December 31, 1999, Niagara Mohawk projects that it will make the following
payments in connection with the IPP and Huntley and Dunkirk swap contracts for
the years 2000 to 2004, and thereafter:

Niagara Mohawk Energy's marketing activities generally consist of transactions
entered into to hedge the market fluctuations of contractual and anticipated
commitments. Gas futures and electric forward contracts are used for hedging
purposes. Changes in market value of futures and forward contracts relating to
hedged items are deferred until the physical transaction occurs, at which time,
income or loss is recognized.

At December 31, 1999, Niagara Mohawk Energy's open positions consisted of long
and short gas futures and long electric forward contracts with approximate fair
values as follows:



1999 1998
FAIR VALUE UNITS Fair Value Units
POSITIONS (IN THOUSANDS) (IN THOUSANDS) (in thousands) (in thousands)

Gas - Long $ 9,596 3,920 DTH $ 4,794 2,470 Dth

Electric - Long $125,026 4,493 MWH $13,141 428 MWh

Electric - Short - - - -



The fair value of both the open gas and electric positions for non-trading
purposes at December 31, 1999 and 1998, as well as the effect of these
activities on Holdings' results of operations for the same period endings were
not material.

The fair value of futures and forward contracts are determined using quoted
market prices.

Niagara Mohawk's investments in debt and equity securities consist of trust
funds for the purpose of funding the nuclear decommissioning of Unit 1 and its
share of Unit 2 (see Note 3 - Nuclear Plant Decommissioning), investments held
by Opinac and a trust fund for certain pension benefits. Holdings and Niagara
Mohawk have classified all investments in debt and equity securities as
available for sale and have recorded all such investments at their fair market
value at December 31, 1999.

The nuclear decommissioning trust funds comprise over 73% of the investments in
debt and equity securities. The agreement to sell the nuclear generation assets
includes the transfer of the decommissioning trust funds, at an agreed amount,
to the buyer. In anticipation of that sale, and to reduce the risk of a
detrimental market shift affecting the funds, Niagara Mohawk converted all
decommissioning assets to high grade, short-term commercial paper in October and
November of 1999. The instruments purchased have specified coupon rates and
maturity dates of generally 1 to 4 months. Remaining cash is invested in an
overnight, short-term investment fund. Due to the current makeup of the funds
the book and market values are approximately equal therefore the decommissioning
funds no longer experience any substantial unrealized gains or losses. These
Actions also increased the sales activity for 1999 affecting both the proceeds
reported and the realized gains and losses.

The proceeds from the sale of investments were $463.9 million, $202.1 million,
and $159.7 million in 1999, 1998, and 1997, respectively. Net realized and
unrealized gains and losses related to the nuclear decommissioning trust are
reflected in "Accumulated depreciation and amortization" on the Consolidated
Balance Sheets, which is consistent with the method used by Niagara Mohawk to
account for the decommissioning costs recovered in rates. The unrealized gains
and losses related to the investments held by the pension trust and Opinac for
the period ending December 31, 1999 are not material to Holdings' results of
operations.

The recorded fair values and cost basis of Holdings and Niagara Mohawk's
investments in debt and equity securities is as follows:

NOTE 10. STOCK BASED COMPENSATION

Under Holdings' stock compensation plans, stock units and stock appreciation
rights ("SARs") may be granted to officers, key employees and directors. In
addition, Holdings' plans allow for the grant of stock options to officers. The
table below sets forth the activity under Holdings' stock compensation plans for
the years 1997 through 1999. On March 18, 1999, Niagara Mohawk's common stock
was exchanged for Holdings' common stock and the SARs, the stock units and the
options were likewise exchanged. (See Note 1.)

Stock units are payable in cash at the end of a defined vesting period,
determined at the date of the grant, based upon Holdings' stock price for a
defined period. SARs become exercisable, as determined at the grant date, and
are payable in cash based upon the increase in Holdings' stock price from a
specified level. As such, for these awards, compensation expense is recognized
over the vesting period of the award based upon changes in Holdings' stock price
for that period. Options granted over the period 1992 to 1995 are currently
exercisable with expirations ten years from the grant date. These options are
all considered to be antidilutive for EPS calculations. Included in Holdings
and Niagara Mohawk's results of operations for the years ending 1999, 1998 and
1997, is approximately $(1.9) million, $9.8 million and $3.2 million,
respectively, related to these plans.

As permitted by SFAS No. 123 - "Accounting for Stock-Based Compensation" ("SFAS
No. 123") Holdings' has elected to follow Accounting Principles Board Opinion
No. 25-"Accounting for Stock Issued to Employees" ("APB No. 25") and related
interpretations in accounting for its employee stock options. Since stock units
and SARs are payable in cash, the accounting under APB No. 25 and SFAS No. 123
is the same. Therefore, the pro forma disclosure of information regarding net
income, as required by SFAS No. 123, relates only to Holdings' outstanding stock
options, the effect of which is immaterial to the financial statements for the
years ended 1999, 1998 and 1997. There is no effect on earnings per share for
these years resulting from the pro-forma adjustments to net income.



NOTE 11. SEGMENT INFORMATION

Holdings is organized between regulated and unregulated activities. Within the
regulated business, Niagara Mohawk, which has 98% of total assets and 94% of
total revenues, there are two principal business units: Energy Delivery and
Nuclear. As discussed in Note 2, Niagara Mohawk is in the process of selling
its remaining fossil and nuclear generation assets. Although there are two
identified business units, financial performance and resource allocation are
measured and managed at the regulated business level.

Holdings and Niagara Mohawk use a shareholder value based management system. The
measure of shareholder value creation is Economic Value Added ("EVA("). EVA(
is the financial measure used to evaluate projects, allocate resources and
report and provide performance incentives.

Holdings' unregulated activities do not meet the reporting thresholds of SFAS
No. 131, but comprise a substantial portion of "other" in the accompanying
table.

* Includes amortization of the MRA regulatory asset in 1998 and 1999.
** Excludes the tax benefit of $12.189 million associated with the extraordinary
item for the loss on extinguishment of debt recorded in 1999.

EVA( is calculated as Net Operating Profit after Taxes less a charge for
the use of capital employed. The capital charge is determined by applying a
rate representing an estimate of investors' expected return given the risk of
the business and a targeted capital structure. The rate is not the same as the
embedded cost of capital, and in particular does not reflect the return on
equity that may be established in a rate proceeding. Certain adjustments to
accounting data are made to more closely reflect operating or economic results.
In each of the three years, an adjustment was made to include the recognition of
the liability for remaining future over-market contracts with IPPs and the
corresponding recognition of imputed interest on that liability. In addition,
there was a significant adjustment in 1998 to reflect the re-capitalization for
EVA( purposes of the PowerChoice charge and the incremental operating
expenses associated with the January 1998 ice storm.

EVA(is further segmented between EVA( from Operations and EVA(
related to the IPPs. This distinction is used to allow management to
focus on operating performance separate from the consequences of the IPP
contracts, the MRA regulatory asset and finance decisions related to managing
the capitalization of Holdings.

A reconciliation of total segment Economic Value Added to total consolidated net
income for the years ended December 31, 1999, 1998 and 1997 is as follows:

NOTE 12. QUARTERLY FINANCIAL DATA (UNAUDITED)

Operating revenues, operating income, net income (loss) and earnings (loss) per
common share by quarters from 1999, 1998 and 1997, respectively, are shown in
the following tables. Quarterly information for Holdings prior to 1999 is
Niagara Mohawk's, but has been reclassified to reflect Holdings' structure.
Holdings and Niagara Mohawk, in their opinion, have included all adjustments
necessary for a fair presentation of the results of operations for the quarters.
Due to the seasonal nature of the regulated utility business, the annual amounts
are not generated evenly by quarter during the year. Niagara Mohawk's quarterly
results of operations reflect the seasonal nature of its business, with peak
electric loads in summer and winter periods. Gas sales peak in the winter.

(said Original Indenture, together with all instruments stated to be
supplemental thereto to which the Trustee has heretofore been or shall hereafter
be a party, including said enumerated Supplemental Indentures and this
Supplemental Indenture, being herein referred to as the "Indenture"); and

WHEREAS, the Indenture provides in Section 1 of Article Twelfth thereof
that without any action or consent by, or notice to, the holders of any of the
Bonds, the Company and the Trustee, from time to time and at any time, may enter
into such indentures supplemental to the Original Indenture as shall be by them
deemed necessary or desirable for the purpose of establishing the form, terms,
provisions and conditions of a particular series of Bonds, and of providing the
terms and conditions of redemption of Bonds of such series, or for a retirement
fund or other fund for such series, or for any other purpose not inconsistent
with the terms of the Indenture and which shall not impair the security of the
same; and

WHEREAS, the Company desires to enter into this indenture supplemental to
the Original Indenture with the Trustee for the purpose of establishing the
form, terms, provisions and conditions of a new series of Bonds under the
Indenture and for the purpose of providing the terms and conditions of
redemption of the Bonds of such new series, and for a maintenance fund, all as
determined by resolution or resolutions of the Board of Directors of the
Company; and

WHEREAS, the Company in the exercise of the authority and power reserved to
it under and by virtue of the provisions of the Indenture and pursuant to
appropriate resolutions of its Board of Directors has duly resolved and
determined to make, execute and deliver to the Trustee a supplemental
indenture in the form hereof and for the purposes herein provided; and

WHEREAS, all conditions and requirements necessary to make this
Supplemental Indenture a valid, binding and legal instrument in accordance
with its terms have been performed and fulfilled and the execution and
delivery hereof have been in all respects duly authorized;

NOW, THEREFORE, THIS SUPPLEMENTAL INDENTURE

W I T N E S S E T H:

That for and in consideration of the premises and of the purchase or
acceptance of the Bonds by those who shall hold the same from time to time and
of the sum of One Dollar to the Company duly paid by the Trustee at or before
the execution and delivery of this Supplemental Indenture and for other good and
valuable consideration, the receipt whereof is hereby acknowledged, the Company
does hereby covenant and agree with the Trustee for the benefit of the holders
of the Bonds, or any of them, issued or to be issued under the Indenture, as
follows:

PART I.

CREATION OF A SERIES OF FIRST MORTGAGE BONDS,
6 7/8% SERIES DUE MARCH 1, 2001

SECTION 1. The Company hereby creates and establishes a new series of
Bonds to be issued under and secured by the Indenture to be designated "First
Mortgage Bonds, 6 7/8% Series due March 1, 2001" (hereinafter sometimes referred
to as the "Bonds of the Seventy-eighth Series").

The permitted principal amount of the Bonds of the Seventy-eighth Series
which may be executed by the Company and authenticated by the Trustee is limited
so that at no time shall there be authenticated, delivered or outstanding under
the Indenture Bonds of the Seventy-eighth Series for a principal amount
exceeding $210,000,000, except that Bonds of the Seventy-eighth Series may
always be issued as provided in Section 2 of Article Fourth of the Indenture.

Upon the execution of this Supplemental Indenture, the Company may execute
and deliver to the Trustee from time to time not in excess of $210,000,000
aggregate principal amount of Bonds of the Seventy-eighth Series, and thereupon
the Trustee, without awaiting the filing or recording of this Supplemental
Indenture but upon receipt of specified evidence of due compliance by the
Company with the applicable provisions of the Indenture, shall authenticate the
said $210,000,000 principal amount of Bonds of the Seventy-eighth Series and
deliver the same upon the written order of the Company signed in its name by its
President or one of its Vice Presidents or its Treasurer or an Assistant
Treasurer.

SECTION 2. The Bonds of the Seventy-eighth Series shall mature according
to their terms on March 1, 2001 and, in the case of the initial authentication
of the Bonds of the Seventy-eighth Series, shall be dated March 1, 1994 and
shall bear interest from such date at the rate per annum specified in the
designation of such series, payable semi-annually on March 1 and September 1 in
each year (computed on the basis of a 360-day year of twelve 30-day months).
Definitive Bonds of said series shall be registered Bonds without coupons and
shall be issued in denominations of $1,000 and multiples thereof.

Subsequent to the initial authentication of the Bonds of the Seventy-eighth
Series, each Bond of the Seventy-eighth Series shall be dated as of the date of
its authentication, and shall bear interest from the March 1 or September 1, as
the case may be, next preceding the date of such Bond to which interest has been
paid or provided for (unless the date of such Bond is a March 1 or a September 1
to which interest has been paid or provided for, in which case such Bond shall
bear interest from its date, or unless the date of such Bond is prior to the
payment of any interest on the Bonds of the Seventy-eighth Series, in which case
such Bond shall bear interest from March 1, 1994). However, so long as there
is no existing default in the payment of interest on the Bonds of the
Seventy-eighth Series, any such Bond authenticated by the Trustee after the
close of business on the record date (as hereinafter in this Section 2 defined)
for any interest payment date and prior to such interest payment date shall be
dated the date of its authentication, but shall bear interest from such interest
payment date; provided, however, that if and to the extent the Company shall
default in the payment of interest on such interest payment date, then such Bond
shall bear interest from the March 1 or September 1, as the case may be, next
preceding the date of such Bond to which interest has previously been paid or
made available for payment on the outstanding Bonds of the Seventy-eighth Series
or, if no interest has been paid on such Bonds, from March 1, 1994.

The interest payable on any interest payment date shall be paid to the
persons in whose names the Bonds of the Seventy-eighth Series were registered at
the close of business on the record date for such payment of interest
notwithstanding any cancellation of Bonds of the Seventy-eighth Series upon any
registration of transfer or exchange thereof between such record date and such
interest payment date; except that if the Company shall default in the payment
of any interest due on such interest payment date such defaulted interest shall
be paid to the persons in whose names Bonds of the Seventy-eighth Series are
registered either at the close of business on the date preceding the date of
payment of such defaulted interest or on a subsequent record date fixed for the
payment of such defaulted interest by notice given by mail by or on behalf of
the Company to holders of Bonds of the Seventy-eighth Series not less than ten
days preceding such subsequent record date. The term "record date" as used
herein shall mean, with respect to a regular semiannual interest payment date,
the close of business on the fifteenth day of the calendar month next preceding
such interest payment date or, if such fifteenth day shall be a day on which
banking institutions in The City of New York are authorized by law to close, the
next preceding day which shall not be a day on which such institutions are so
authorized to close or, in the case of defaulted interest, the close of business
on any subsequent record date established as provided above.

All of the Bonds of the Seventy-eighth Series shall be executed in the name
and on behalf of the Company by a facsimile of the signature (or manual
signature) of its President or a Vice President, and imprinted with its
corporate seal (or a facsimile thereof), attested by a facsimile of the
signature (or manual signature) of its Secretary or an Assistant Secretary.

Bonds of the Seventy-eighth Series shall be lettered "RU" and numbered
consecutively from RU-1 upwards, or shall bear such other letters as may be
provided therefor by the Board of Directors of the Company.

Both principal of and interest on the Bonds of the Seventy-eighth Series
shall be payable at the office of the Trustee, which in the case of Marine
Midland Bank shall be its corporate trust office in the Borough of Manhattan,
The City of New York, State of New York, or at such other office or agency in
the Borough of Manhattan, The City of New York, State of New York, as shall be
maintained by the Company for such purpose, in such coin or currency of the
United States of America as at the time of payment shall be legal tender for
public and private debts.

SECTION 3. The Company shall not have the right to redeem the outstanding
Bonds of the Seventy-eighth Series, either as a whole or in part, on any date
prior to maturity.

The Bonds of the Seventy-eighth Series are also not subject to redemption,
either as a whole or in part, by operation of any sinking fund, debt retirement
fund or maintenance fund referred to in Part II hereof.

SECTION 4. The registered owner (or assigns) of any Bond of the
Seventy-eighth Series may at any time surrender the same at the corporate trust
office of the Trustee, or at any other office or agency of the Trustee or the
Company maintained for such purpose, and with instruments of transfer
satisfactory to the Trustee, and subject to the terms, conditions and
limitations specified in the Indenture, shall be entitled to receive in exchange
therefor an equal principal amount of Bonds of said series of other authorized
denominations; and the Company will provide, and the Trustee shall authenticate
and deliver, the Bonds necessary to make such exchange. The provisions of
Section 12 of Article Second of the Original Indenture to the contrary
notwithstanding, no payment of a service charge shall be required for any
exchange or registration of transfer, but the Company may require payment of a
sum sufficient to cover any tax or other governmental charge that may be imposed
in relation thereto.

SECTION 5. The definitive Bonds of the Seventy-eighth Series, and the
Trustee's Certificate to be inscribed on all Bonds of said series, are to be
substantially in the forms following, respectively:

[FORM OF REVERSE OF DEFINITIVE BOND
OF THE SEVENTY-EIGHTH SERIES]

This Bond is one of a duly authorized issue of Bonds of the Company, of an
unlimited (except as provided in the Indenture hereinafter mentioned) permitted
principal amount, all issued or to be issued in one or more series (the Bonds of
the series of which this Bond is a part being herein called the "Bonds of the
Seventy-eighth Series"), all of the Bonds of all series being issued or to be
issued under and, irrespective of the time of issue, all equally secured by a
Mortgage Trust Indenture (herein, with all instruments stated to be supplemental
thereto to which the Trustee hereinafter named is or shall be a party, called
the "Indenture"), dated as of October 1, 1937, to Marine Midland Bank (successor
to Marine Midland Bank, N.A., a national banking association and, in turn, a
successor to Marine Midland Bank, a New York corporation, formerly named The
Marine Midland Trust Company of New York, Marine Midland Grace Trust Company of
New York and Marine Midland Bank -- New York and hereinafter, with its
successors as defined in the Indenture, referred to as the "Trustee"), to which
Indenture, an executed counterpart of which is on file with the Trustee,
reference is hereby made for a description of the property mortgaged and pledged
to the Trustee, and for a statement of the nature and extent of the security,
the rights of the holders of the Bonds with respect to such security, and the
terms and conditions upon which said Bonds are or are to be issued and secured;
but neither the foregoing reference to the Indenture, nor any provision of this
Bond or of the Indenture, shall affect or impair the obligation of the Company,
which is absolute and unconditional, to pay, at the stated or accelerated
maturities herein provided, the principal of and interest on this Bond as herein
provided.

The Indenture and the rights and obligations of the Company and of the
holders of the Bonds thereunder may be changed or modified at any time upon the
consent and approval of the Company and of the holders of 66-2/3 per cent in
principal amount of the Bonds then outstanding affected by such change or
modification, given as provided in the Indenture, and in the manner and subject
to the limitations therein set forth; provided, that no such change or
modification shall (a) alter or impair the obligation of the Company to pay the
principal of, and premium, if any, and interest on any Bond at the time and
place and at the rate and in the currency provided therein, without the consent
of the holder of such Bond, (b) permit the creation by the Company of any
mortgage, or lien in the nature of a mortgage, ranking prior to or pari passu
with the lien of the Indenture, or alter adversely to the Bondholders the
character of the lien of the Indenture, except as in the Indenture otherwise
expressly provided, unless the creation of such mortgage or lien, or such
alteration of the lien of the Indenture, be consented to by the holders of all
outstanding Bonds, (c) affect the Trustee unless consented to by the Trustee or
(d) permit a reduction of the percentage required for any change or modification
of the Indenture, without the consent of the holders of all outstanding Bonds.

The principal of this Bond together with accrued interest thereon may be
declared, or may become, due and payable before maturity in certain events, on
the conditions, in the manner and with the effect set forth in the Indenture.

Subsequent to the initial authentication of the Bonds of the Seventy-eighth
Series, each Bond of the Seventy-eighth Series shall be dated as of the date of
its authentication, and shall bear interest from the March 1 or September 1, as
the case may be, next preceding the date of such Bond to which interest has been
paid or provided for (unless the date of such Bond is on a March 1 or a
September 1 to which interest has been paid or provided for, in which case such
Bond shall bear interest from its date, or unless the date of such Bond is prior
to the payment of any interest on the Bonds of the Seventy-eighth Series, in
which case such Bond shall bear interest from March 1, 1994). However, so long
as there is no existing default in the payment of interest on the Bonds of the
Seventy-eighth Series, any such Bond authenticated by the Trustee after the
close of business on the record date for any interest payment date and prior to
such interest payment date shall be dated the date of its authentication, but
shall bear interest from such interest payment date; provided, however, that if
and to the extent that the Company shall default in the payment of interest on
such interest payment date, then such Bond shall bear interest from the March 1
or September 1, as the case may be, next preceding the date of such Bond to
which interest has previously been paid or made available for payment on the
outstanding Bonds of the Seventy-eighth Series or, if no interest has been paid
on such Bonds, from March 1, 1994.

The Bonds of the Seventy-eighth Series are entitled to the benefit of a
maintenance fund referred to in Part II of the Supplemental Indenture creating
the Bonds of the Seventy-eighth Series. The Bonds of the Seventy-eighth Series
may not be redeemed at the option of the Company, either as a whole or in part,
and are not subject to redemption, either as a whole or in part, by operation of
any sinking fund, debt retirement fund or the maintenance fund referred to in
Part II of the Supplemental Indenture creating the Bonds of the Seventy-eighth
Series.

No recourse shall be had for the payment of any part of principal of, or
interest on, this Bond or for any claim based hereon or thereon, or otherwise in
any manner with respect hereto, or with respect to the Indenture, to or against
any incorporator or any past, present or future stockholder, officer or director
of the Company or of any successor corporation, either directly or through the
Company or any successor corporation, whether by virtue of any constitution,
statute or other provision of law, or by the enforcement of any assessment or
penalty, or otherwise, all such liability being expressly waived and released by
the acceptance of this Bond and as part of the consideration for the issue
hereof, as provided in the Indenture.

Registration of transfer of this Bond may be made by the registered owner
(or assigns) in person or by duly authorized attorney, at the corporate trust
office of the Trustee, or at such other offices or agencies of the Trustee or
the Company as shall be maintained for such purpose, upon the surrender of this
Bond, and thereupon a new Bond or Bonds of authorized denominations of the same
series for a like aggregate principal amount will be issued to the registered
transferee, all in the manner and subject to the terms, conditions and
limitations specified in the Indenture. No service charge shall be made for any
exchange or registration of transfer, but the Company may require payment of a
sum sufficient to cover any tax or other governmental charge that may be imposed
in relation thereto. The Company and the Trustee may deem and treat the person
in whose name this Bond is registered as the absolute owner hereof for the
purpose of receiving payment of or on account of the principal and interest due
hereon (subject to the provisions of the first paragraph of this Bond), and for
all other purposes, and neither the Company, the Trustee nor any paying agent or
agency shall be affected by any notice to the contrary, whether this Bond or
interest shall be overdue or not.

PART II.

MAINTENANCE FUND PROVISIONS AND
RESTRICTIONS AS TO DIVIDENDS

SECTION 1. The Company covenants that so long as any of the Bonds of the
Seventy-eighth Series shall be outstanding, it will comply with the provisions
of Section 22 (providing for a maintenance fund for the benefit of Bonds issued
under the Indenture) and Section 23 (providing for certain restrictions on the
payment of dividends) of Article Fifth of the Indenture as added by the

publication of notice of such meeting, as a record date for the
determination of holders of Registered Bonds without coupons, and of
Coupon Bonds registered as to principal (otherwise than to bearer),
entitled to notice of and to vote at such meeting and any adjournment
thereof, and only such registered holders who shall have been such on
the date so fixed shall be entitled to notice of and to vote such Bonds
at such meeting, and the Registered Bonds without coupons, and the Coupon
Bonds registered as to principal (otherwise than to bearer), on such record
date may be voted at such meeting and any adjournment thereof only by the
persons who shall have been registered holders of such Bonds on such record
date or their proxies, notwithstanding any registration of transfer of any
such Bonds on the books of the Company after such date. If any Registered
Bonds without coupons shall be transferred or shall be exchanged for Coupon
Bonds after such record date, or if any Coupon Bonds registered as to
principal (otherwise than to bearer) on such record date shall thereafter
be registered to bearer, a suitable notation shall be made upon such Bonds
at the time of registration of transfer from such registered holder's name
or exchange, as the case may be, to record the fact that the registered
holder of such Bonds on said record date or his proxies shall be the only
persons entitled to vote such Bonds at the meeting. If any Coupon Bond not
registered as to principal upon such record date is thereafter so
registered (otherwise than to bearer) or is thereafter exchanged for a
Registered Bond, the first registered holder in whose name such Bond shall
be so registered shall be deemed to have been the registered holder of such
Bond on the record date for the purposes of this section, and upon such
registration or exchange a notice of such meeting shall be delivered to
such registered holder. In any case where a record date is fixed as
aforesaid, the list of Bondholders referred to in Paragraph B of this
Section 2 shall be based upon the holdings of Bonds on such record date,
but shall also include the holder of Coupon Bonds registered as to
principal (otherwise than to bearer) after such record date and prior to
such meeting and the holders of Registered Bonds received in exchange for
Coupon Bonds after such record date and prior to such meeting."

SECTION 5. The Company reserves the right, without any consent or other
action by holders of the Bonds of the Seventy-eighth Series or of any
subsequently created series, to amend at any time Article Twelfth of the
Indenture, as it may heretofore, hereby and hereafter be or have been
supplemented and amended, by adding the following Paragraph G to Section 2
thereof:

"G. Whenever the Company shall deliver to the Trustee an instrument or
instruments executed by holders of at least sixty-six and two-thirds per
centum (66-2/3%) in aggregate principal amount of the Bonds affected and
outstanding at the time of such delivery, consenting to the substance of a
proposed modification or amendment to the provisions hereof, thereupon the
Trustee shall execute a supplemental indenture in substantially the form
provided for by or in such instrument or instruments, and no holder of any
Bond shall have any right or interest to object to the execution of said
supplemental indenture or to object to any of the terms or provisions
therein contained, or the operation thereof, or in any manner to question
the propriety of the execution thereof, or to enjoin or restrain the
Trustee or the Company from executing the same or from taking any action
pursuant to the provisions thereof, provided that, in lieu of an instrument
or instruments executed by holders of Bonds, the consent of the holders of
any series of Bonds to any such proposed modification or amendment may be
set forth in and evidenced by the supplemental indenture establishing the
terms and provisions of such series; and provided further that no such
change or modification shall (a) alter or impair the obligation of the
Company to pay the principal and interest on any Bond outstanding at the
time and place and at the rate and in the currency prescribed therein,
without the consent of the holder of such Bond, (b) permit the creation by
the Company of any mortgage, or lien in the nature of a mortgage, ranking
prior to or pari passu with the lien of the Indenture, or alter adversely
to the Bondholders the character of the lien of the Indenture, except as
in the Indenture otherwise expressly provided, unless the creation of such
mortgage or lien, or such alteration of the lien of the Indenture, be
consented to by the holders of all outstanding Bonds, (c) affect the
Trustee unless consented to by the Trustee or (d) permit a reduction of the
percentage required for any change or modification of the Indenture,
without the consent of the holders of all outstanding Bonds.

It shall not be necessary for any consent of Bondholders under this Section
to approve the particular form of any proposed supplemental indenture, but
it shall be sufficient if such consent approves the substances of the
matters to which such consent relates. Any consent executed and delivered
by any Bondholder shall be binding upon all future holders of Bonds held by
such Bondholder at the time of execution of such consent, including without
limitation any Bonds issued in substitution or exchange therefor, whether
upon transfer or otherwise."

SECTION 6. The Company reserves the right, without any consent or other action
by holders of the Bonds of the Seventy-eighth Series or of any subsequently
created series, to amend at any time Article Thirteenth of the Indenture, as
it may heretofore, hereby and hereafter be o have been supplemented and
amended, by amending the first paragraph of Section 1 thereof so that, as so
amended, it shall be and read as follows:

instrument in writing required or provided by this Indenture to be signed
or executed by the holders of any Bonds may be in any number of concurrent
writings of similar tenor, and may be signed or executed by such holders
in person or by attorney appointed in writing.

The fact and date of the execution by any person of any such instrument, or
of the writing appointing any such attorney, and of the ownership by any
person of any Bonds, may be proved in any manner deemed sufficient by the
Trustee, and such proof shall be conclusive in favor of the Trustee and the
Company.

Without limiting the generality of the foregoing paragraph:

A. The signature on a proxy, consent or other such instrument or writing,
if believed by the Trustee to be genuine, shall be sufficient to establish
the fact of the execution thereof.

B. The fact of the ownership of any Coupon Bond which shall not at the
time be registered as to principal or shall be registered to bearer, and
the denomination and serial number of such Bond and the date of holding the
same, may be proved by a certificate executed by any trust company, bank,
banker or other depositary (wherever situated), showing that at the date
therein mentioned the person named in such certificate had on deposit with
such depositary the Bond described in such certificate. For all purposes
of this Indenture and of any proceedings pursuant hereto for the
enforcement hereof or otherwise, to the extent permitted by the provisions
of Section 4 of Article Tenth, such person shall be deemed to continue to
be the owner of such Bond until the Trustee shall have received notice in
writing to the contrary. The ownership of any Registered Bond or of any
Coupon Bond which shall at the time be registered as to principal
(otherwise than to bearer) shall be proved by the register of Bonds
maintained for such purpose."

SECTION 7. The Company reserves the right, without any consent or other
action by holders of the Bonds of the Seventy-eighth Series or of
subsequently created series, to amend at any time Article Fourth of the
Indenture, as it may heretofore, hereby and hereafter be or have been
supplemented and amended, by amending subparagraph (3) of Paragraph E of

President or a Vice President and the Treasurer or an Assistant Treasurer
of the Company, and verified on information and belief by one of such
officers not more than sixty (60) days prior to the receipt thereof by
the Trustee, certifying

(a) that the Bonds so delivered had previously been actually negotiated
by the Company for value;
(b) that the Company had bona fide purchased or contracted to purchase
the said Bonds, Underlying Mortgage Obligations and Constituent
Corporation Bonds at prices (inclusive of accrued interest) to be
set forth in the statement, and that such prices were not in excess
of 115% of the principal amount of said Bonds, Underlying Mortgage
Obligations and Constituent Corporation Bonds;
(c) that the Company is not, so far as known to the officers signing such
statement, in default with respect to the performance or observance
of any covenant or agreement contained in this Indenture; and
(d) that it is not then necessary to retire the Underlying Mortgage
Obligations to be purchased to eliminate any excess of the nature
described in Paragraph D of Section 7 hereof."

action by holders of the Bonds of the Seventy-eighth Series or of any

of the sum of One Dollar to the Company duly paid by the Trustee at or before
the execution and delivery of this Supplemental Indenture and for other good and
valuable consideration, the receipt whereof is hereby acknowledged, the Company
does hereby covenant and agree with the Trustee for the benefit of the holders
of the Bonds, or any of them, issued or to be issued under the Indenture, as
follows:

PART I

AMENDMENT AND RESTATEMENT
OF THE SUPPLEMENTAL INDENTURE CREATING
THE FIFTY-SIXTH SERIES OF FIRST MORTGAGE BONDS

SECTION 1. At such time as all Prior First Mortgage Bonds issued under the
Prior Supplemental Indenture not heretofore canceled by the Trustee or delivered
to the Trustee canceled or for cancellation have been delivered to the Trustee
by the registered holder thereof, the Prior Supplemental Indenture shall be
amended and restated as this Supplemental Indenture.

PART II

AMENDMENT AND RESTATEMENT OF THE FIFTY-SIXTH SERIES
OF FIRST MORTGAGE

SECTION 1. At such time as all Prior First Mortgage Bonds issued under the
Prior Supplemental Indenture not heretofore canceled by the Trustee or delivered
to the Trustee canceled or for cancellation have been delivered to the Trustee
by the registered holder thereof, such Prior First Mortgage Bonds shall be
amended and restated and redesignated as the "First Mortgage Bonds, 5.15% Series
due November 1, 2025" it (hereinafter sometimes referred to as the "Bonds of the
Eighty-eighth Series").

The permitted principal amount of the Bonds of the Eighty-eighth Series
which may be amended and restated by the Company and executed by the Company in
connection therewith and authenticated by the Trustee is limited so that at no
time shall there be authenticated, delivered or outstanding under the Indenture,
Bonds of the Eighty-eighth Series for a principal amount exceeding $75,000,000,
except that Bonds of the Eighty-eighth Series may always be issued as provided
in Section 2 of Article Fourth of the Indenture.

Upon the execution of this Supplemental Indenture, the Trustee, without
awaiting the filing or recording of this Supplemental Indenture but upon receipt
of evidence of due compliance by the Company with the applicable provisions of
the Indenture, shall authenticate, pursuant to Section 10 of Article Second of
the Indenture, the Bonds of the Eighty-eighth Series and deliver the same to the
NYSERDA Bond Trustee in exchange for certificates representing the same
principal amount of the Prior First Mortgage Bonds delivered to the Trustee by
the NYSERDA Bond Trustee, all such actions to occur simultaneously with delivery
of the NYSERDA Bonds.

SECTION 2. The Bonds of the Eighty-eighth Series shall mature according to
their terms on November 1, 2025 and, in the case of the initial authentication
of the Bonds of the Eighty-eighth Series, shall be dated November 19, 1998 and
shall bear interest from November 19, 1998 at the rate per annum specified in
the designation of such series, payable semi-annually on November 1 and May 1 in
each year (computed on the basis of a 360-day year of twelve 30-day months).
Definitive Bonds of said series shall be registered Bonds without coupons and
shall be issued in denominations of $1,000 and multiples thereof.

Subsequent to the initial authentication of the Bonds of the Eighty-eighth
Series, each Bond of the Eighty-eighth Series shall be dated as of the date of
its authentication and shall bear interest from November 19, 1998.

Notwithstanding any other provision contained herein, the obligation of the
Company to make payments of the principal of and premium, if any, and interest
on the Bonds of the Eighty-eighth Series shall be fully or partially satisfied
and discharged, and the amount of any such payment shall be reduced, to the
extent that the Trustee shall have received written notice, not less than 10
days prior to the date on which any such payment would otherwise be due, that
moneys are available under the NYSERDA Bond Indenture for the payment, in full
or in part, of principal and premium, if any, and interest then due on the
NYSERDA Bonds and the Trustee shall not have received written notice from the
Company that the obligation of the Company shall not be so satisfied and
discharged and the amount of any such payment so reduced.

The interest payable on any interest payment date shall be paid to the
persons in whose names the Bonds of the Eighty-eighth Series were registered at
the close of business on the record date for such payment of interest (except
any such Bond which has been called for redemption on a date fixed for such
redemption which is after such record date and prior to such interest payment
date) notwithstanding any cancellation of Bonds of the Eighty-eighth Series upon
any registration of transfer or exchange thereof between such record date and
such interest payment date; except that if the Company shall default in the
payment of any interest due on such interest payment date such defaulted
interest shall be paid to the persons in whose names Bonds of the Eighty-eighth
Series are registered either at the close of business on the date preceding the
date of payment of such defaulted interest or on a subsequent record date fixed
for the payment of such defaulted interest by notice given by mail by or on
behalf of the Company to holders of Bonds of the Eighty-eighth Series not less
than ten days preceding such subsequent record date. The term "record date" as
used herein shall mean, with respect to a regular semi-annual interest payment
date, the close of business on the fifteenth day of the calendar month next
preceding such interest payment date or, if such fifteenth day shall be a day on
which banking institutions in The City of New York are authorized by law to
close, the next preceding day which shall not be a day on which such
institutions are so authorized to close or, in the case of defaulted interest,
the close of business on any subsequent record date established as provided
above.

All of the Bonds of the Eighty-eighth Series shall be executed in the name
and on behalf of the Company by a facsimile of the signature (or manual
signature) of its President or a Vice President, and imprinted with its
corporate seal (or a facsimile thereof), attested by a facsimile of the
signature (or manual signature) of its Secretary or an Assistant Secretary.

Bonds of the Eighty-eighth Series shall be lettered "RU" and numbered
consecutively from RU-1 upwards, or shall bear such other letters as may be
provided therefor by the Board of Directors of the Company.

Both principal of and interest on the Bonds of the Eighty-eighth Series (as
well as any premium thereon applicable in case of any redemption thereof prior
to maturity) shall be payable at the office of the Company's paying agent, which
in the case of The Marine Midland Bank, shall be its corporate trust office in
the Borough of Manhattan, The City of New York, State of New York, or at such
other office or agency in the Borough of Manhattan, The City of New York, State
of New York, as shall be maintained by the Company for such purpose, in such
coin or currency of the United States of America as at the time of payment shall
be legal tender for public and private debts.

SECTION 3. The Company, at its option, shall have the right to redeem the
outstanding Bonds of the Eighty-eighth Series, either as a whole or in part, on
any date on or after November 19, 2008 and prior to maturity, whether or not an
interest payment date, upon notice given as hereinafter in this Section 3
provided, at the applicable redemption prices provided in the form of the
definitive Bond of the Eighty-eighth Series as contained in Section 4 of this
Part II, together with interest accrued to the date fixed for redemption. The
Bonds of the Eighty-eighth Series may also be redeemed at the option of the
Company, at any time, either as a whole or in part, at the redemption price
equal to 100% of the principal amount thereof, together with interest accrued to
the date fixed for redemption, upon the occurrence of any of the events
specified in Section 2.02.6 of the NYSERDA Bond Indenture.

The Bonds of the Eighty-eighth Series are subject to mandatory redemption
in the event of any optional or mandatory redemption of the NYSERDA Bonds, on
the date fixed for such mandatory redemption of the NYSERDA Bonds, upon notice
given as hereinafter in this Section 3 provided, at the applicable redemption
price specified in the NYSERDA Bond Indenture for the NYSERDA Bonds being
redeemed, in such amount as, together with any moneys available therefor under
the NYSERDA Bond Indenture, shall be required, in accordance with the provisions
of the Participation Agreement, to pay the principal of and premium, if any, and
interest on the NYSERDA Bonds so redeemed.

The Bonds of the Eighty-eighth Series are also subject to mandatory
redemption, as a whole but not in part, upon receipt by the Trustee and the
Company of a written statement (the "Redemption Statement") from the NYSERDA
Bond Trustee that the principal of all NYSERDA Bonds then outstanding has been
declared to be immediately due and payable pursuant to Section 10.01 of the
NYSERDA Bond Indenture. The Company shall thereupon fix a redemption date, to
occur not more than 90 days following receipt of the Redemption Statement, and
shall promptly give written notice thereof (the "Redemption Notice") to the
Trustee and the NYSERDA Bond Trustee. No Redemption Notice shall be deemed to
have been given, and the Bonds of the Eighty-eighth Series shall not be
redeemed, if a written cancellation of the Redemption Statement by the NYSERDA
Bond Trustee is delivered to the Trustee and the Company prior to the receipt of
the Redemption Notice by the NYSERDA Bond Trustee. Any such redemption of the
Bonds of the Eighty-eighth Series shall be at the redemption price equal to 100%
of the principal amount thereof, together with interest accrued to the date
fixed for redemption.

No redemption of the Bonds of the Eighty-eighth Series, either as a whole
or in part, may be made except in connection with the payment of a like
principal amount of NYSERDA Bonds, either by redemption or at maturity (stated
or otherwise).

In case the Company shall at any time desire or be required so to redeem
part or all of the Bonds of the Eighty-eighth Series then outstanding, the
Company shall give to the Trustee notice in writing at least 45 days prior to
the redemption date fixed by the Company (unless a shorter notice shall be
satisfactory to the Trustee) of the principal amount of Bonds of such series
which it desires or is required to redeem, specifying the date on which it
desires or is required to make redemption. There shall be furnished to the
Trustee a certificate or opinion executed by the President or a Vice-President
and the Treasurer or an Assistant Treasurer of the Company stating that the
conditions precedent specified in this Section 3 with respect to such redemption
have been complied with and the Trustee may conclusively rely thereon. As soon
as practicable thereafter, if the Bonds are to be redeemed in part, the Trustee
shall select in any manner deemed by it proper the serial numbers of the Bonds
to be redeemed in whole or in part and shall notify the Company in writing of
the serial numbers of the Bonds so selected. The Company shall thereupon cause
to be mailed to the respective registered owners of the Bonds of the
Eighty-eighth Series designated for redemption, not more than 45 days prior to
the date of redemption, at their addresses appearing upon the Bond registration
books, a notice of such intended redemption, stating the redemption date and the
redemption price and designating the serial numbers of the Bonds of the
Eighty-eighth Series to be redeemed in whole or in part and the portion of the
principal amount of any such Bonds to be redeemed in part and requiring that
such Bonds be surrendered on the redemption date at the corporate trust office
of the Trustee, or at such other office or agency as shall be maintained by the
Company for such purpose, for redemption at the said redemption price, giving
notice also that interest on such Bonds or such portions of Bonds will not
accrue after the designated redemption date. If less than the whole of the
principal of any Bond shall be called for redemption, said notice shall also
state that such Bond is to be redeemed in part, and that, upon the presentation
of such Bond for redemption, there will be issued, in lieu of the unredeemed
portion of the principal thereof, a new Bond or Bonds of the same series for an
aggregate principal amount equal to such unredeemed portion.

The Trustee may, to the extent permitted by the provisions of Section 4 of
Article Tenth of the Indenture, accept the certificate of the President or any
Vice President or the Treasurer of the Company as sufficient evidence that the
requirements as to mailing of notices of the call for redemption have been fully
complied with or the Trustee may, at its option and at the expense and on behalf
of the Company, give such notice and take any other action required of the
Company in connection with such redemption.

SECTION 4. On or prior to the redemption date specified in any such
notice, the Company shall deposit with the Trustee a sum of money, of the
character specified as the medium of payment in the Bonds of the Eighty-eighth
Series called for redemption, which together with any moneys available therefor
under the NYSERDA Bond Indenture is sufficient to redeem, at the redemption
price payable as hereinbefore provided, the Bonds of such series designated for
redemption and the called part of any Bond of such series called only in part,
and to pay the interest accrued thereon up to said redemption date, to be
applied by the Trustee to the payment of such Bonds (and the called part of any
such Bond) and such accrued interest thereon upon presentation and surrender of
such Bonds, together with duly executed instruments of transfer, at the
corporate trust office of the Trustee, or at such other office or agency as
shall be maintained by the Company for such purpose; and, after such deposit
shall have been made, such Bonds so called in whole and the called part of any
such Bond called only in part, whether or not presented for redemption, shall
cease to be entitled to any benefit, lien or security under the Indenture, no
interest will accrue thereon on or after the redemption date duly specified in
said notice, and claims for interest, if any, appertaining to such Bonds, and
the called part of any such Bond called only in part, maturing after that date
shall be void. All Bonds so redeemed shall forthwith be canceled and, upon its
written request, delivered to the Company or otherwise disposed of; and no Bonds
shall be issued hereunder in place of any such Bonds, except as otherwise
provided in Article Fourth of the Indenture and except that, if less than the
entire principal amount of any Bond shall be so redeemed, upon presentation of
such Bond so called in part, with proper instruments of transfer if required, at
or after the time fixed for the payment of said Bonds so called for redemption,
payment of the principal amount of the part thereof so called shall be made upon
surrender and cancellation of said Bond so presented, and one or more Bonds of
the Eighty-eighth Series, for a principal amount equal to the uncalled and
unpaid balance of the principal amount of such Bond, will be executed by the
Company and shall be authenticated and delivered by the Trustee to the owner of
such Bond, without expense to such owner.

SECTION 5. The registered owner (or assigns) of any Bond of the
Eighty-eighth Series may at any time surrender the same at the corporate trust
office of the Trustee, or at any other office or agency of the Trustee or the
Company maintained for such purpose, and with instruments of transfer
satisfactory to the Trustee, and, subject to the terms, conditions and
limitations specified in the Indenture, shall be entitled to receive in exchange
therefor an equal principal amount of Bonds of said series of other authorized
denominations; and the Company will provide, and the Trustee shall authenticate
and deliver, the Bonds necessary to make such exchange. The provisions of
Section 12 of Article Second of the Original Indenture to the contrary
notwithstanding, no payment of a service charge shall be required for any
exchange or registration of transfer, but the Company may require payment of a
sum sufficient to cover any tax or other governmental charge that may be imposed
in relation thereto.

SECTION 6. The definitive Bonds of the Eighty-eighth Series, and the Trustee's
Certificate to be inscribed on all Bonds of said series, are to be
substantially in the forms following, respectively:

PART IV

PROVISIONS RELATING TO INSTITUTIONAL

SECTION 1. Any term of the Indenture or of the Bonds of the Eighty-eighth
Series to the contrary notwithstanding, so long as the NYSERDA Bond Trustee
(herein called the "Original Holder") or any of its nominees shall be a holder
of any of the Bonds of the Eighty-eighth Series, or if any other institutional
holder or its nominee or nominees shall at any time be the holder or holders of
at least 5% in aggregate principal amount of the Bonds of the Eighty-eighth

make a notation thereon of all principal, if any, paid on such Bond and will
also note the date to which interest has been paid on such Bond, and (b)
promptly notify the Company and the Trustee of the name and address of the
transferee of any such Bond so sold or transferred by such holder. Upon request

Trustee shall not be liable or responsible to the Original Holder or any
Institutional Holder or to the Company or to any other person for any act or
omission to act on the part of the Company or the Original Holder or such
Institutional Holder in connection with the foregoing. The Company will
indemnify and save the Trustee harmless against any liabilities resulting from
any such act or omission.

Series to the contrary notwithstanding, so long as the Original Holder or any
Institutional Holder, or a nominee of the Original Holder or such Institutional
Holder, shall be a holder of any of the Bonds of the Eighty-eighth Series in
case of any partial redemption of the Bonds of the Eighty-eighth Series the
Trustee shall prorate the principal amount of such Bonds to be redeemed among
all holders of Bonds of such series in proportion to the principal amount of
such Bonds registered in the name of each such holder and shall then designate
for redemption with respect to each such holder particular Bonds of such series
or portions thereof equal to the principal amount of Bonds to be redeemed so
prorated to such registered owner; provided, however, that in any such prorating
pursuant to this paragraph the Trustee shall, according to such method as it
shall deem proper in its discretion, make such adjustments by increasing or
decreasing by not more than $1,000 the amount which would be allocable on the
basis of exact proportion to any one or more holders of such Bonds, as may be
required to provide that the principal amount so prorated shall be in each
instance an integral multiple of $1,000.

PART V

aggregate principal amount of the Bonds outstanding, or to any
suit instituted by any holder of Bonds for the enforcement of the
payment of the principal of (or premium, if any) or interest on
any Bond on or after the maturity date expressed in such Bond."

SECTION 3. The Company reserves the right, without any consent or other
action by holders of the Bonds of the Eighty-eighth Series or of any
subsequently created series, to amend at any time Article Eleventh of the
Indenture, as it may heretofore, hereby and hereafter be or have been

"SECTION 2. Anything herein contained to the contrary
notwithstanding, any moneys at any time deposited with the Trustee

principal, premium or interest of or upon any Bond or interest
coupon and remaining unclaimed for three (3) years after the date
upon which such payment shall have become due shall, upon the
request of the Company, be repaid to it by the Trustee; provided,
that, before being required to make any such repayment, the
Trustee may, at the expense of the Company, cause to be published,
once a week for four (4) successive calendar weeks, in a daily
newspaper, printed in the English language, published and of
general circulation in the Borough of Manhattan, The City of New
York, State of New York, and in a daily newspaper, printed in the

terms of the Bond or interest coupon with respect to which such
moneys were deposited, notice that the said moneys have not been
claimed, and that after a date named in such notice, the balance
of such moneys then unclaimed will be repaid to the Company."

SECTION 4. The Company reserves the right, without any consent or other
action by holders of the Bonds of the Eighty-eighth Series or of any
subsequently created series, to amend at any time Article Twelfth of the
Indenture, as it may heretofore, hereby and hereafter be or have been
supplemented and amended, by amending Paragraph A of Section 2 of Article
Twelfth of the Indenture by the addition of the following:

"The Trustee may, and upon written request of the Company or of
the holders of a majority in principal amount of the Bonds
outstanding, shall, fix a day, not less than ten (10) days prior
to the date of first publication of notice of such meeting, as a
record date for the determination of holders of Registered Bonds
without coupons, and of Coupon Bonds registered as to principal
(otherwise than to bearer), entitled to notice of and to vote at
such meeting and any adjournment thereof, and only such registered
holders who shall have been such on the date so fixed shall be
entitled to notice of and to vote such Bonds at such meeting, and
the Registered Bonds without coupons, and the Coupon Bonds
registered as to principal (otherwise than to bearer), on such
record date may be voted at such meeting and any adjournment
thereof only by the persons who shall have been registered holders
of such Bonds on such record date or their proxies,
notwithstanding any registration of transfer of any such Bonds on
the books of the Company after such date. If any Registered Bonds
without coupons shall be transferred or shall be exchanged for
Coupon Bonds after such record date, or if any Coupon Bonds
registered as to principal (otherwise than to bearer) on such
record date shall thereafter be registered to bearer, a suitable
notation shall be made upon such Bonds at the time of registration
of transfer from such registered holder's name or exchange, as the
case may be, to record the fact that the registered holder of such
Bonds on said record date or his proxies shall be the only persons
entitled to vote such Bonds at the meeting. If any Coupon Bond
not registered as to principal upon such record date is thereafter
so registered (otherwise than to bearer) or is thereafter
exchanged for a Registered Bond, the first registered holder in
whose name such Bond shall be so registered shall be deemed to
have been the registered holder of such Bond on the record date
for the purposes of this section, and upon such registration or
exchange a notice of such meeting shall be delivered to such
registered holder. In any case where a record date is fixed as
aforesaid, the list of Bondholders referred to in Paragraph B of
this Section 2 shall be based upon the holdings of Bonds on such
record date, but shall also include the holders of Coupon Bonds
registered as to principal (otherwise than to bearer) after such
record date and prior to such meeting and the holders of
Registered Bonds received in exchange for Coupon Bonds after such
record date and prior to such meeting."

SECTION 5. The Company reserves the right, without any consent or other
action by holders of the Bonds of the Eighty-eighth Series or of any
subsequently created series, to amend at any time Article Twelfth of the
Indenture, as it may heretofore, hereby and hereafter be or have been
supplemented and amended, by adding the following Paragraph G to Section 2
thereof:

"G. Whenever the Company shall deliver to the Trustee an
instrument or instruments executed by holders of at least
sixty-six and two-thirds per centum (66_%) in aggregate principal
amount of the Bonds affected and outstanding at the time of such
delivery, consenting to the substance of a proposed modification
or amendment to the provisions hereof, thereupon the Trustee
shall execute a supplemental indenture in substantially the form
provided for by or in such instrument or instruments, and no
holder of any Bond shall have any right or interest to object to
the execution of said supplemental indenture or to object to any
of the terms or provisions therein contained, or the operation
thereof, or in any manner to question the propriety of the
execution thereof, or to enjoin or restrain the Trustee or the
Company from executing the same or from taking any action pursuant
to the provisions thereof, provided that, in lieu of an instrument
or instruments executed by holders of Bonds, the consent of the
holders of any series of Bonds to any such proposed modification
or amendment may be set forth in and evidenced by the supplemental
indenture establishing the terms and provisions of such series;
and provided further that no such change or modification shall
(a) alter or impair the obligation of the Company to pay the
principal and interest on any Bond outstanding at the time and
place and at the rate and in the currency prescribed therein,
without the consent of the holder of such Bond, (b) permit the
creation by the Company of any mortgage, or lien in the nature of
a mortgage, ranking prior to or pari passu with the lien of the
Indenture, or alter adversely to the Bondholders the character of
the lien of the Indenture, except as in the Indenture otherwise
expressly provided, unless the creation of such mortgage or lien,
or such alteration of the lien of the Indenture, be consented to
by the holders of all outstanding Bonds, (c) affect the Trustee
unless consented to by the Trustee or (d) permit a reduction of
the percentage required for any change or modification of the
Indenture, without the consent of the holders of all outstanding
Bonds.

It shall not be necessary for any consent of Bondholders under
this Section to approve the particular form of any proposed
supplemental indenture, but it shall be sufficient if such consent
approves the substance of the matters to which such consent
relates. Any consent executed and delivered by any Bondholder
shall be binding upon all future holders of Bonds held by such
Bondholder at the time of execution of such consent, including
without limitation any Bonds issued in substitution or exchange
therefor, whether upon transfer or otherwise."

SECTION 6. The Company reserves the right, without any consent or other
action by holders of the Bonds of the Eighty-eighth Series or of any
subsequently created series, to amend at any time Article Thirteenth of the
Indenture, as it may heretofore, hereby and hereafter be or have been
supplemented and amended, by amending the first paragraph of Section 1 thereof
so that, as so amended, it shall be and read as follows:

"SECTION 1. Any demand, consent, waiver, request, notice or other
instrument in writing required or provided by this Indenture to be
signed or executed by the holders of any Bonds may be in any
number of concurrent writings of similar tenor, and may be signed
or executed by such holders in person or by attorney appointed in
writing.

The fact and date of the execution by any person of any such
instrument, or of the writing appointing any such attorney, and
of the ownership by any person of any Bonds, may be proved in any
manner deemed sufficient by the Trustee, and such proof shall be
conclusive in favor of the Trustee and the Company.

Without limiting the generality of the foregoing paragraph:

A. The signature on a proxy, consent or other such instrument or
writing, if believed by the Trustee to be genuine, shall be
sufficient to establish the fact of the execution thereof.

B. The fact of the ownership of any Coupon Bond which shall not
at the time be registered as to principal or shall be
registered to bearer, and the denomination and serial number
of such Bond and the date of holding the same, may be proved
by a certificate executed by any trust company, bank, banker
or other depositary (wherever situated), showing that at the
date therein mentioned the person named in such certificate
had on deposit with such depositary the Bond described in such
certificate. For all purposes of this Indenture and of any
proceedings pursuant hereto for the enforcement hereof or
otherwise, to the extent permitted by the provisions of
Section 4 of Article Tenth, such person shall be deemed to
continue to be the owner of such Bond until the Trustee shall
have received notice in writing to the contrary. The
ownership of any Registered Bond or of any Coupon Bond which
shall at the time be registered as to principal (otherwise
than to bearer) shall be proved by the register of Bonds
maintained for such purpose."

SECTION 7. The Company reserves the right, without any consent of other action
by holders of the Bonds of the Eighty-eighth Series or of any subsequently
created series, to amend at any time Article Fourth of the Indenture, as it may
heretofore, hereby and hereafter be or have been supplemented and amended, by
amending subparagraph (3) of Paragraph E of Section 9 thereof so that, as so
amended, it shall be and read as follows:

"(3) A statement, in form satisfactory to the Trustee, signed by
the President or a Vice President and the Treasurer or an
Assistant Treasurer of the Company, and verified on information
and belief by one of such officers not more than sixty (60) days
prior to the receipt thereof by the Trustee, certifying (a) that
the Bonds so delivered had previously been actually negotiated by
the Company for value; (b) that the Company had bona fide
purchased or contracted to purchase said Bonds, Underlying
Mortgage Obligations and Constituent Corporation Bonds at prices
(inclusive of accrued interest) to be set forth in the statement,
and that such prices were not in excess of 115% of the principal
amount of said Bonds, Underlying Mortgage Obligations and
Constituent Corporation Bonds; (c) that the Company is not, so far
as known to the officers signing such statement, in default with
respect to the performance or observance of any covenant or
agreement contained in this Indenture; and (d) that it is not
then necessary to retire the Underlying Mortgage Obligations to be
purchased to eliminate any excess of the nature in Paragraph D of
Section 7 hereof."

SECTION 8. The Company reserves the right, without any consent or other action
by holders of the Bonds of the Eighty-eighth Series or of any subsequently
created series, to amend at any time Article Seventh of the Indenture, as it may
heretofore, hereby and hereafter be or have been supplemented and amended, by
amending Paragraph E of Section 2 thereof so that, as so amended, it shall be
and read as follows:

"E. To the purchase of Bonds of any series issued and outstanding
hereunder or of Underlying Mortgage Obligations or of Constituent
Corporation Bonds at not in excess of 115% of the principal amount
thereof, in accordance with the provisions of Paragraph E of
Section 9 of Article Fourth."]

classes of Small Consumers (including farms) throughout the state,
giving due consideration to the demonstrated ability of the candidate
agencies to provide sufficient resources to identify and to represent
the interests of such consumers before federal, state and local
governmental agencies, and to coordinate with other groups having
similar interests. The remaining two (2) percent of the total votes
on the Management Committee allocated to the governmental agency
subsector shall be exercised by governmental agencies that advocate
on behalf of Small Consumers, other than the agency selected as the
State-Wide Consumer Advocate, and governmental agencies that act as

entitled to cast one (1) vote. The eight (8) percent of the votes on
the Management Committee allocated to the State Public Power
Authorities subsector shall be split into an affirmative component
based on the votes for the pending motion, and a negative component
based on votes against the pending motion, in direct proportion to the
votes cast for and against the motion, rounded to two decimal places.

(ii) Seven (7) percent of the total votes on the Management Committee shall
be allocated to the Municipal Electric Systems and Cooperatively Owned
Electric Systems subsector. Each Party in the Municipal Electric
Systems and Cooperatively Owned Electric Systems subsector shall be
entitled to cast one (1) vote. The seven percent of the votes on the
Management Committee allocated to Municipal Electric Systems and
Cooperatively Owned Electric Systems subsector shall be split into
an affirmative component based on the votes for the pending motion,

be allocated to the Environmental Parties subsector. Parties in this
subsector must be environmental organizations that have been certified
by the ISO Board under Section 2.02. Each Party in the Environmental
Parties subsector shall be entitled to cast one (1) vote. The two
percent of the votes on the Management Committee allocated to the
Environmental Parties subsector shall be split into an affirmative
component based on the votes for the pending motion, and a negative
component based on votes against the pending motion, in direct
proportion to the votes cast for and against the motion, rounded

7.07 ACTIVATION OF SECTORS AND SUBSECTORS

In order for certain sectors and subsectors to exercise their right to vote
on measures before the Management Committee they must be activated. The
requirements with respect to the activation of a sector or subsector apply
to each sector and subsector, except the following: the Transmission Owners
sector, the State Public Power Authorities subsector of the Public Power/
Environmental Parties sector, and the governmental agency subsector of the
End-Use Consumer sector. The Transmission Owners sector, the State Public
Power Authorities subsector and the governmental agency subsector shall always
be active.

Each sector and subsector that is subject to the activation criteria shall have
a minimum of five (5) parties, excluding affiliates, to be activated and to vote
on matters before the Management Committee.

The voting share allocated to a sector that has not been activated shall be
assigned in equal proportions to all active sectors and subsectors until the
inactive sector is activated. Upon activation of an inactive sector, the
activated sector shall be allocated a voting share pursuant to Section 7.06 of
this Agreement. The voting share allocated to a subsector that has not been
activated shall be allocated within the sector in which the subsector resides in
accordance with the determination of the then members of the sector in which the
subsector resides; provided, however, that the governmental agency subsector
shall never exercise more than five (5) percent of the total votes on the
Management Committee and the Environmental Parties subsector shall never
exercise more than two (2) percent of the total votes on the Management
Committee. Upon activation of an inactive subsector the activated subsector
shall be allocated the vote percentage pursuant to Section 7.06 of this
Agreement.

7.08 QUORUM

The attendance, as provided for in Section 7.03, by a quorum of at least
three (3) sectors shall constitute a quorum for action by the Management
Committee. A quorum of a sector shall be five (5) members of a sector or fifty
(50) percent of the Parties in a sector, whichever is less. Parties in a sector
that has achieved a quorum, shall be entitled to cast the entire vote allocated
to their sector. In a sector that is divided into subsectors, if there is a
quorum for the sector the Parties in each subsector shall exercise the full
voting share allocated to their subsector. If none of the Parties in a
subsector vote, the voting share of the subsector in which no Parties vote shall
be reallocated to the other subsectors of that sector on a proportional basis
according to the relative voting weight of the subsectors; provided, however,
that the governmental agency subsector shall never exercise more than five (5)
percent of the total votes on the Management Committee and the Environmental
Parties subsector shall never exercise more than two (2) percent of the total
votes on the Management Committee.

In the event the designated representatives are unable to resolve the dispute
by mutual agreement, such dispute may be submitted to the DRA. The party
submitting the matter to the DRA shall include a written statement describing
the nature of the dispute and the issues to be resolved. Any subsequent
mediation or arbitration process shall be limited to the issues presented

interest in the matter to be mediated. Any individual designated as
mediator shall make known to the disputing parties any such disqualifying
relationship or interest and a new mediator shall be designated.

unable or unwilling to serve, the individual last stricken from the list
shall be designated and the process repeated until an individual is selected
that is able and willing to serve.

4. The disputing parties shall attempt in good faith to resolve their
dispute in accordance with the schedule established by the mediator. In no
event may the schedule extend beyond thirty (30) days from the date of

non-binding recommendation to resolve the dispute. The recommendation
shall include an assessment by the mediator of the merits of the principal
positions being advanced by each of the parties to the dispute.

distribute a list of qualified arbitrators to the disputing parties.

2. Absent the express written consent of all disputing parties, no person
shall be eligible for selection as an arbitrator that is a past or present

shall be designated and the process repeated until an individual is
selected that is able and willing to serve.

4. The arbitrator shall have no power to modify or change any agreement, tariff
or rule, or otherwise create any additional rights or obligations for any
party. The scope of the arbitrator's decision shall be limited to the
issues presented for arbitration.

5. The arbitrator shall determine discovery procedures, intervention
rights, how evidence shall be taken, what written submittals may be made,
and other procedural matters, taking into account the complexity of the
issues involved, the extent to which factual matters are disputed, and the
extent to which the credibility of witnesses is relevant to a resolution.
Each disputing party shall produce all evidence determined by the
arbitrator to be relevant to the issues presented. To the extent such
evidence involves proprietary or Confidential Information, the arbitrator
may issue an appropriate protective order which shall be complied with by
all disputing parties. The arbitrator may elect to resolve the arbitration

policies, or would address all issues in dispute, the arbitrator shall
develop a compromise solution consistent with the terms of this Agreement.
A written decision explaining the basis for the award shall be provided by
the arbitrator to the parties and the DRA. No award shall be deemed to be
precedential in any other arbitration related to a different dispute.

Market Participants will be required to communicate all information to the ISO
that is necessary for the ISO to dispatch their resource or Load using the
OASIS. As part of the OASIS, the ISO shall establish and operate an exchange
mechanism using an electronic technology to process the bids.

ARTICLE 14: SALE OF TRANSMISSION CONGESTION CONTRACTS

14.01 PRIMARY SALES.

Transmission Congestion Contracts ("TCCs") shall be sold in the primary market
by either a centralized auction process or directly by the individual
Transmission Owners in a non-discriminatory manner.

14.02 SECONDARY SALES.

TCCs may be offered, resold, and assigned on a secondary market, either in
their entirety or subdivided.

14.03 AUCTION BIDS.

The TCC auction bids will be made in accordance with the ISO OATT.

14.04 MARKET CLEARING PRICES.

Each winning bidder in the auction shall pay the Market Clearing Price for the
TCCs. The total revenues received from the sale of TCCs, the Market Clearing
Prices, and the entities awarded TCCs shall be posted on OASIS.

14.05 REVENUES REMITTED.

Any and all revenue received from the sale of a TCC shall be remitted to the
Primary Owner of the TCC or the owner of the applicable transmission assets.

ARTICLE 15: TAX-EXEMPT FINANCING

15.01 TAX-EXEMPT FINANCING PURSUANT TO SECTION 142(F) OF IRC.

Except for Section 15.05, this Article is applicable only to Transmission
Owners that have financed facilities for the local furnishing of electricity
as described in Section 142(f) of the Internal Revenue Code ("Local Furnishing
Bond"). Notwithstanding any other provision of the ISO Agreement or an ISO
Tariff, neither the ISO nor a Transmission Owner shall be required to provide
Transmission Service or any other service to any Customer pursuant to an ISO
Tariff if the provision of such Transmission Service or other service would
result in the loss of tax-exempt status of any Local Furnishing Bonds used to
finance the Transmission Owner's facilities.

Notwithstanding any other provision of this Agreement, no Transmission Owner
shall be required to accept or consent to any request, recommendation, or
decision, including, without limitation, a recommendation or a decision of an
Arbitrator, or to build any facilities or to take any action, including, without
limitation, the providing of Transmission Service or any other service, or to
enter into any agreement if, in the sole judgment of such Transmission Owner,
such request, recommendation, decision, facilities, action, Transmission Service
or agreement might reasonably be expected to result in litigation related to the
tax-exempt status of the Local Furnishing Bonds or any other tax-exempt debt
obligation, or might reasonably be construed to adversely affect or bring into
question the tax-exempt status of interest on bonds or other obligations issued
by or for the benefit of such Transmission Owner, or adversely affect or bring
into question the ability of such Transmission Owner to deduct interest
payments or to access the benefits of tax-exempt financing in the future.

15.02 ALTERNATIVE PROCEDURES FOR REQUESTING TRANSMISSION SERVICE.

a. If a Transmission Owner determines that the provision of Transmission
Service to be provided under the ISO OATT would jeopardize the tax-exempt
status of any Local Furnishing Bonds, the Transmission Owner shall advise
the ISO within thirty (30) days of receipt of a Completed Application by
an Customer requesting such service, or the date on which the ISO OATT
becomes effective.

b. If a Customer thereafter renews its request for the same Transmission
Service referred to in (a) by tendering an application under Section 211
of the FPA, the Transmission Owner, within ten (10) days of receiving a
copy of the Section 211 request, will waive its right to receive a request
for service under Section 213(a) of the FPA. The Commission, upon receipt
of the Transmission Owner's waiver of its right to a request for service
under Section 213(a) of the FPA, shall issue an Order under Section 211 of
the FPA. Upon issuance of the Order under Section 211 of the FPA, the ISO
and the Transmission Owner shall be required to provide the requested
Transmission Service in accordance with the terms and conditions of the ISO
Tariff.

15.03 SECTION 211 ORDER.

The provision of Transmission Service under the ISO OATT shall also
constitute the provision of Transmission Service pursuant to an Order by the
Commission under Section 211 of the FPA with respect to the transmission of
electricity on Con Edison's and LIPA's transmission systems.

15.04 TAX-EXEMPT FINANCING PURSUANT TO SECTION 103 AND RELATED PROVISIONS
OF INTERNAL REVENUE CODE.

This provision is applicable only to NYPA which has financed transmission
facilities with the proceeds of bonds issued pursuant to Section 103 and
related provisions of the Internal Revenue Code ("Government Bonds").
Notwithstanding any other provision of the ISO OATT Tariff, neither the ISO
nor NYPA shall be required to provide Transmission Service to any Market
Participant pursuant to the ISO OATT if the provision of such Transmission
Service would result in the loss of the tax-exempt status of any Government
Bonds or impair NYPA's ability to issue future tax-exempt obligations.

15.05 RESPONSIBILITY OF COSTS ASSOCIATED WITH LOSS OF TAX-EXEMPT
STATUS.

If, by virtue of an order issued by the Commission pursuant to Section 211
of the FPA, the ISO or a Transmission Owner is required to provide Transmission
Service that would adversely affect the tax-exempt status of a Transmission
Owner's Local Furnishing Bonds or any other tax-exempt debt obligations, then
the Market Participant receiving such Transmission Service will compensate the
Transmission Owner for all costs, if any, associated with the loss of
tax-exempt status plus the normal costs of Transmission Service.

15.06 TRANSMISSION SERVICE EFFECTS ON TAX-EXEMPT FINANCING BY LIPA

This provision is applicable only to LIPA which has financed transmission
facilities with the proceeds of LIPA's tax-exempt bonds issued pursuant to the
Internal Revenue Code. Notwithstanding any other provisions of the ISO OATT
or the ISO Services Tariff, neither the ISO nor the Transmission Owner shall
be required to provide transmission service to any Customer pursuant to an ISO
Tariff if the provisions of such Transmission Service would result in loss of
tax-exempt status of any tax-exempt bonds or impair LIPA's ability to issue
future tax exempt obligations. If, by virtue of an order issued by the
Commission pursuant to Section 211 of the FPA, the ISO or a Transmission Owner
is required to provide Transmission Service that would adversely affect the
tax-exempt status of LIPA's tax-exempt bonds or any other tax-exempt debt
obligations, then the Customer receiving such Transmission Service will
compensate LIPA for all costs, if any, associated with the loss of tax-exempt
status of LIPA's tax-exempt bonds on such other tax exempt obligations plus
the normal costs of Transmission Service.

ARTICLE 16: PENALTIES FOR NON-PERFORMANCE

16.01 ISO RIGHTS AND OBLIGATIONS.

In the event that a Transmission Owner, Generator, marketer, or LSE should
perform, or fail to perform, or fail to follow the ISO's instructions or orders

municipal instrumentality of the state of New York, and LIPA (a subsidiary of
the Long Island Power Authority, a corporate municipal instrumentality of the
state of New York)(herein referred to collectively as the "Transmission
Owners") and the New York Independent System Operator ("ISO"), a not-for-profit
corporation. The Transmission Owners and the ISO are herein referred to
collectively as the Parties.

WITNESSETH:

WHEREAS, the Investor-Owned Transmission Owners established the New York
Power Pool ("NYPP") by agreement made as of the 21st day of July, 1966, and
NYPA subsequently joined NYPP on October 11, 1967, and LIPA joined the NYPP
on May 28, 1998; and

WHEREAS, the Transmission Owners have created, invested in and operated the
interconnected transmission facilities in New York State and each Investor-Owned
Transmission Owner has fiduciary responsibilities to assure, among other things,
the receipt of adequate revenues to maintain the facilities, a reasonable rate
of return on its transmission facilities, and to provide for recovery of the
capital invested in its transmission facilities; and

WHEREAS, the ISO's principal mission is to maintain the integrity and
reliability of the interconnected transmission facilities of the Transmission
Owners, which will require the ISO to exercise Operational Control of the
transmission facilities of the Transmission Owners, referred to as "Transmission
Facilities Under ISO Control," and will further require the ISO, among other
things, to function as the successor to NYPP with respect to certain NYS Power
System operational activities heretofore conducted by NYPP; and

WHEREAS, the Investor-Owned Transmission Owners have legal obligations to
provide safe and reliable service to the public, including assuring suitable
use of their individual transmission facilities to attain and maintain
compliance with this obligation; and

WHEREAS, the Transmission Owners will continue to own, physically operate,
modify, and maintain the Transmission Facilities Under ISO Operational Control,
and the Investor-Owned Transmission Owners will continue to have fiduciary
obligations to their investors to protect their transmission facilities and to
protect their investors from liability that may result from the operation of
those facilities;

NOW, THEREFORE, in consideration of the premises and the mutual covenants and
agreements set forth herein, the Parties do hereby agree with each other, for
themselves and their successors and assigns, as follows:



ARTICLE 1.0: DEFINITIONS

1.01 The definitions contained in Article 1 of the Independent System
Operator Agreement ("ISO Agreement") as it existed on the date this Agreement
is signed by the Parties are hereby incorporated by reference in their entirety
into this Agreement. Modifications to such definitions under the ISO Agreement
shall apply to this Agreement, only if the Parties to this Agreement agree in
writing pursuant to Section 6.14 below.

ARTICLE 2.0: RESPONSIBILITIES OF THE TRANSMISSION OWNERS

2.01 TRANSMISSION FACILITIES. The Transmission Owners have specified
transmission facilities over which the ISO will have day-to-day Operational
Control. These facilities shall be collectively known as the "Transmission
Facilities Under ISO Operational Control," and are listed in Appendix A-1.
The Transmission Owners also will be responsible for providing notification
to the ISO with respect to actions related to other specified transmission
facilities. These facilities shall be collectively known as "Transmission
Facilities Requiring ISO Notification," and are listed in Appendix A-2.
Transmission facilities may be added to, or deleted from, the lists of
facilities provided in Appendices A-1 and A-2 by mutual written agreement
of the ISO and the Transmission Owner owning and controlling such facilities.
A current version of such list will be posted on the ISO's OASIS.

2.02 TRANSMISSION SYSTEM OPERATION. Each Transmission Owner shall operate
and maintain its facilities that are designated as Transmission Facilities
Under ISO Operational Control and Transmission Facilities Requiring ISO
Notification in accordance with the terms of this Agreement and in accordance
with all Reliability Rules and all other applicable operating instructions,
and ISO Procedures. The Operating Committee of the ISO will promulgate
procedures to provide for the assumption of authority by the Transmission
Owners' control centers to respond to an Emergency. These procedures shall
provide for the coordination of such response with the ISO. The procedures
will provide that, in situations where immediate action is required, the
Transmission Owners' control centers will have the authority to take actions,
including without limitation, the following:

1. exercising control over facilities listed in Appendix A-1 of this
Agreement and generating units;
2. starting quick start generation and the adjustment of generation;
3. re-energizing transmission facilities following breaker trips;
4. implementing emergency Load Shedding and voltage reduction measures and
subsequent restoration;
5. voltage/VAR control during an Emergency;
6. changing ratings of transmission facilities; and
7. taking other measures consistent with Good Utility Practice that are
required to respond to the Emergency.

Until the Operating Committee promulgates such procedures, the Transmission
Owners will exercise the above responsibilities during an Emergency.

2.03 LOCAL AREA TRANSMISSION SYSTEM FACILITIES. Transmission system
facilities not designated as Transmission Facilities Under ISO Operational
Control or as Transmission Facilities Requiring ISO Notification shall be
collectively known as "Local Area Transmission System Facilities." Each
Transmission Owner shall have sole responsibility for the operation of its
Local Area Transmission System Facilities, provided, however, that such
operation by each Transmission Owner shall not compromise the reliable and
secure operation of the NYS Transmission System. Each Transmission Owner
shall promptly comply to the extent practicable with a request from the ISO
to take action with respect to coordination of the operation of its Local Area
Transmission System Facilities.

2.04 SAFE OPERATIONS. Notwithstanding any other provision of this
Agreement, a Transmission Owner may take such action with respect to the
operation of its facilities as it deems necessary to maintain Safe Operations.
To ensure Safe Operations, all Transmission Owner local operating rules shall
govern the connection and disconnection of generation with transmission
facilities. Safe Operations include the application and enforcement of rules,
procedures and protocols that are intended to ensure the safety of personnel
operating or performing work or tests on transmission facilities.

2.05 LOCAL CONTROL CENTER, METERING AND TELEMETRY. Each Transmission Owner
shall operate, or arrange for a suitable third party to operate, on a
twenty-four (24) hour basis, a suitable control center, and shall install and
maintain all other equipment and facilities reasonably required for the ISO to
exercise Operational Control over Transmission Facilities Under ISO Operational
Control. Operation of the NYS Power System will be a cooperative effort
coordinated by the ISO control center in conjunction with each Transmission
Owner's control center and will require the exchange of all reasonably
necessary information. The Transmissions Owners' control centers must provide
the ISO with Supervisory Control and Data Acquisition ("SCADA") information on
facilities listed in Appendices A-1 and A-2 as well as on certain generation
resources in their Transmission Districts.

Each Transmission Owner shall have the responsibility for providing metering
data in its Transmission District to the ISO, unless other parties are
authorized by the appropriate regulatory authority to provide metering data.
Each Transmission Owner shall be responsible for collecting and making
available to the ISO billing quality metering data and any other information
for the Transmission District required by the ISO for billing purposes. The
Parties agree that the metering and data acquisition systems currently in place
will be acceptable for initial ISO operation. The Transmission Owner shall
cooperate with the ISO in implementing reasonable metering enhancements and new
metering installations that the ISO may deem necessary, provided that mechanisms
satisfactory to each Transmission Owner are in place for their recovery of all
associated costs. Each Transmission Owner shall continue to receive telemetry
from existing Generators in its Transmission District and provide for the
receipt of such information from new Generators. Automatic Generation Control
("AGC") will be implemented via each Transmission Owner's control center. Each
Transmission Owner shall operate its control center to comply with current AGC
procedures, as well as any revised or new AGC procedures reasonably adopted by
the ISO. In addition, each Transmission Owner shall provide backup control
services to the ISO in the event the ISO's computer systems malfunction. In
such situations, Bid curves will be made available to the Transmission Owners'
control centers to facilitate the continued economic operation of the system.
Each Transmission Owner will maintain a strict Code of Conduct to prevent such
information from reaching any unauthorized person or entity.

2.06 SECURITY CONSTRAINED UNIT COMMITMENT ADJUSTMENTS. A Transmission
Owner may request commitment of additional Generators (including specific
output level(s)) if it determines that an additional Generator is needed to
ensure local area reliability. The ISO will use Supplemental Resource
Evaluation ("SRE") to fulfill a Transmission Owner's request for additional
units.

2.07 DESIGN, MAINTENANCE AND RATING CAPABILITIES. Each Transmission Owner
shall comply with the provisions of this Agreement and all Reliability Rules,
ISO Procedures, and Good Utility Practice with respect to the design,
maintenance and rating the capabilities of NYS Transmission System facilities.

2.08 MAINTENANCE SCHEDULING. The Transmission Owners shall schedule
maintenance of their facilities designated as Transmission Facilities Under ISO
Operational Control and schedule any outages (other than forced transmission
outages) of said transmission system facilities in accordance with outage
schedules approved by the ISO. The Transmission Owners shall comply with
maintenance schedules coordinated by the ISO, pursuant to this Agreement, for
Transmission Facilities Under ISO Operational Control. Each Transmission Owner
shall be responsible for providing notification of maintenance schedules to the
ISO for Facilities Requiring ISO Notification.

2.09 INVESTIGATIONS AND RESTORATION. Each Transmission Owner shall
promptly conduct investigations of equipment malfunctions and failures and
forced transmission outages in a manner consistent with applicable FERC, PSC,
NRC, NERC, NPCC and NYSRC rules, principles, guidelines, standards and
requirements, ISO Procedures and Good Utility Practice. Each Transmission
Owner shall supply the results of such investigations to the NYSRC, the ISO and
the other Transmission Owners. Each Transmission Owner shall determine the
level of resources to be applied to restore facilities to service following a
failure, malfunction, or forced transmission outage. Following a total or
partial system interruption, restoration shall be coordinated between the ISO
and the Transmission Owners' control centers. The Transmission Owners' control
centers shall have the authority, in coordination with the ISO, to restore the
system and to re-establish service if doing so would minimize the period of
service interruption.

2.10 INFORMATION AND SUPPORT. The Transmission Owners shall obtain from
the ISO and the ISO shall provide to the Transmission Owners the necessary
information and support services to comply with their obligations under this
Article.

ARTICLE 3.0: RESPONSIBILITIES OF THE ISO

3.01 OPERATION AND COORDINATION. The ISO shall direct the operation of, and
coordinate the maintenance scheduling of, certain facilities of the NYS Power
System, including coordination with control centers maintained by the
Transmission Owners in accordance with the Reliability Rules, as follows:

for full recovery of the following, to the extent allowed, accepted or
approved by FERC: the Annual Transmission Revenue Requirement of each
of the Investor Owned Transmission Owners, NTAC, the annual
transmission revenue requirement of LIPA, and any Stranded Investment
Recovery Charge;
c. The ISO does not materially and adversely affect the right of any
Transmission Owner concerning transitional arrangements set forth in
the ISO Tariffs, pertaining or relating to Existing Transmission
Agreements which are in effect at the commencement of ISO operations;
d. Con Edison, LIPA and NYPA have adequate assurance in the opinion of
each such entity, that participation in the ISO will not jeopardize
the tax-exempt status of their respective tax-exempt bonds, the
ability of such Investor-Owned Transmission Owner to deduct interest
payments, or the ability of the Transmission Owners to secure future
tax-exempt financing;
e. The ISO does not act in violation of lawful PSC or FERC Orders;
f. The ISO does not file a request under Section 205 of FPA to revise
the provisions in the ISO Services Tariff related to indemnification
and limitation of liability;
g. The ISO does not have a financial interest in any commercial
transaction involving the use of the NYS Power System or any other
electrical system;
h. The ISO does not seek modification of any provision of the ISO OATT
or the ISO Services Tariff so as to require, directly or indirectly,
wheeling to end users except as authorized by the PSC or a retail
access tariff approved by the Long Island Power Authority's Board of
Trustees, or a sham wholesale transaction (as defined in FPA Section
212[h]);
i. The ISO distributes revenues from the collection of transmission
charges to the Transmission Owner in a timely manner; and
j. The ISO enforces and complies with the creditworthiness and
collection standards of the ISO Procedures, the ISO OATT and the

billing and collection of revenues related to services provided by the ISO
pursuant to the terms of the ISO OATT and the ISO Services Tariff.

3.06 NYPA ANNUAL TRANSMISSION REVENUE REQUIREMENT. This Agreement is
premised on NYPA recovering its full annual transmission revenue requirement.
This is to be achieved through a mechanism known as the NTAC. NYPA will submit
its annual revenue requirement for FERC approval. NYPA will be entitled to
receive from the ISO the difference between its FERC-approved revenue
requirement and the sum of revenues it collects from contracts and from TSCs
associated with its current transmission system. The ISO will credit any TCC
revenues associated with NYPA's facilities and allocate the remainder on a kWh
basis to all transmission Load the ISO serves. NYPA's recovery pursuant to
NTAC is limited as described in Attachment H to the ISO OATT. This Agreement
is further premised on each Investor-Owned Transmission Owner being authorized
to fully recover the NTAC charged to its transmission and retail customers and
that any necessary regulatory approvals for such full recovery will be granted
by the PSC and FERC.

3.07 PROPOSED MATERIAL MODIFICATIONS TO THE NYS POWER SYSTEM. The ISO shall
establish procedures to evaluate the impact of any proposed material
modifications to the NYS Power System. If the ISO or a Transmission Owner
determines that a proposed modification will have a negative impact on system
reliability or on total Interface transfer capability over an Interface or
Interfaces, the ISO or the Transmission Owner may refer the issue for resolution
pursuant to procedures comparable to those set forth in Article 5 of the
ISO/NYSRC Agreement. However, the approval of the NYSRC or the ISO shall not
be required to submit the issue to the PSC for resolution.

3.08 OASIS. The ISO shall maintain the OASIS for the New York Control
Area.

3.09 TRANSMISSION OWNER REIMBURSEMENT AND ASSUMPTION OF EXISTING
OBLIGATIONS. As soon as practicable, or no later than a date to be mutually
agreed upon by the Parties, the ISO shall reimburse the Transmission Owners
for all costs associated with the start-up and establishment of the ISO, to
the extent that the ISO is authorized by FERC to recover such costs. Such
costs shall include, but are not limited to, the costs associated with: the
transfer of the current NYPP Control Center buildings and facilities to the
ISO; and start-up and development costs, including but not limited to software
development and licensing costs, project development costs, and regulatory
costs.

The ISO shall assume all existing contractual and other obligations of the
NYPP. If the ISO decides to take action to terminate any such contract or
obligation, or its assumption of existing obligations, it will bear any costs
related thereto. The ISO shall utilize the current facilities and equipment
of the NYPP and retain NYPP employees to the greatest extent practicable.

3.10 TRANSMISSION OWNERS RESERVED RIGHTS. Notwithstanding any other
provision of this Agreement, or any other agreement or amendment made in
connection with the restructuring of the NYPP and establishment of the New York

h. Nothing in this Agreement shall be construed as limiting in any way
the rights of a Transmission Owner to make any filing with the PSC.
i. Notwithstanding anything to the contrary in this Agreement, no
amendment to any provision of this Section may be adopted without the
agreement of the Transmission Owners.

3.11 RETENTION OF NON-TRANSFERRED OBLIGATIONS. Any and all other rights
and responsibilities of a Transmission Owner related to the ownership or
operation of its transmission assets or to its rights to withdraw its assets
from ISO control, that have not been specifically transferred to the ISO under
this Agreement or otherwise addressed under this Agreement, will remain with
the Transmission Owners.

3.12 LIPA SCHEDULING PROCEDURES. LIPA shall develop and file with the ISO
procedures that will be implemented by LIPA on a nondiscriminatory basis. The
procedures shall cover:

(a) LIPA's scheduling of transactions on the Northport-Norwalk intertie;
(b) submitting such schedules to the ISO by the ISO's deadline for
submitting schedules;
(c) developing a preapproved list of transactions that the ISO may
schedule and list of Transmission Customers that may withdraw Energy

ARTICLE 6.0: OTHER PROVISIONS

6.01 TERM AND TERMINATION. This Agreement shall become effective upon the
execution of this Agreement by the Transmission Owners and the ISO and on the
latest of:

(i) the date(s) FERC accepts for filing, without condition or
material modification:

(a) this Agreement;
(b) the ISO Tariffs;
(c) the ISO Agreement;
(d) the NYSRC Agreement; and
(e) the ISO/NYSRC Agreement ("ISO Tariffs" and "ISO Related Agreements");

(ii) the date on which FERC, the PSC and any other regulatory agency having
jurisdiction grant all necessary approvals, including, without limitation,
any approvals required under Section 70 of the Public Service Law and
Section 203 of the FPA;

(iii) September 1, 1999; or

(iv) on such later date specified by FERC.

Without waiving or limiting any of its other rights under this Article, if a
Transmission Owner determines that any of the conditions set forth in Section
3.04 hereof is not being met or ceases to be in full force and effect that
Transmission Owner may withdraw from this Agreement, the ISO Agreement and the
ISO Tariffs and withdraw its assets from the ISO's control and administration
on ninety (90) days prior written notice to all Parties to this Agreement and
FERC. Such notice shall identify the condition or conditions set forth in
Section 3.04 that have not been met or no longer are in full force and effect;
provided, however, that prior to the filing of such notice, the ISO shall be
advised of the specific condition or conditions that are no longer in full
force and effect, and the ISO shall have the opportunity to restore the
effectiveness of the condition or conditions identified within a thirty (30)
day period. If the effectiveness of the condition or conditions is not restored
within thirty (30) days, the Transmission Owner may file a notice of withdrawal
with the ISO and FERC; provided, however, that if the ISO demonstrates that it
has made a good faith effort but has been unable to restore the effectiveness
of the condition or conditions within the thirty (30) day period, the ISO shall
be provided an additional thirty (30) day period to restore the effectiveness
of the condition or conditions and the Transmission Owner may not file the
notice of withdrawal until the expiration of the second thirty (30) day period.
Withdrawal of a Transmission Owner under this Section shall be effective ninety
(90) days after the filing of the notice of withdrawal unless FERC finds that
such withdrawal of an Investor-Owned Transmission Owner is contrary to the
public interest, as that standard has been judicially construed under the
Mobile-Sierra doctrine. However, the Transmission Owner who submitted the
notice of withdrawal may withdraw the notice or extend the withdrawal date.
Nothing in this section shall be construed as a voluntary undertaking by any
Transmission Owner to remain a Party to this Agreement after the expiration of
its notice of withdrawal.

In addition to the foregoing provision, after the fifth anniversary of the
effective date of this Agreement, this Agreement may be terminated by a
unanimous vote of the Transmission Owners or their successors or assignees.
If the Transmission Owners vote to terminate this Agreement, they will file
with FERC and the PSC an explanation of their action and a proposal for an
alternative plan for the safe, reliable and efficient operation of the NYS
Transmission System.

6.02 WITHDRAWAL. Any Transmission Owner may withdraw from this Agreement,
the ISO Agreement and the ISO Tariffs and withdraw its assets from the ISO
control and administration upon ninety (90) days written notice to the ISO
Board and FERC. In the case of an Investor-Owned Transmission Owner, no
further approval by FERC shall be required for such withdrawal from this
Agreement, if such Investor-Owned Transmission Owner has on file with FERC
its own open access transmission tariff and such withdrawal shall be effective
unless FERC finds that such withdrawal is contrary to the public interest, as
that standard has been judicially construed under the Mobile-Sierra doctrine.
Any modification to this Article shall provide any Party with the right to
withdraw from the Agreement pursuant to the unmodified provisions of this
Article, within ninety (90) days of the effective date of such modification.
Notwithstanding any other provision of Article 6, in the event that the
tax-exempt financing of a Party is jeopardized by its participation in the
ISO, the Party may withdraw from this Agreement, the ISO Agreement and the
ISO Tariffs and withdraw any assets from ISO control and administration upon
thirty (30) days prior written notice to the ISO Board.

6.03 OBLIGATIONS AFTER TERMINATION OR WITHDRAWAL.

a. Following termination or withdrawal from the Agreement, a Party shall
remain liable for all obligations arising hereunder prior to the
effective date of termination or withdrawal, including all obligations
accrued prior to the effective date, imposed on the Party by this
Agreement or the ISO Tariffs or other ISO Related Agreements.
b. Termination or the withdrawal from this Agreement shall not relieve a
Party of any continuing obligation it may have under the ISO Tariffs
and ISO Related Agreements, unless the Party also withdraws from the
ISO Tariffs or ISO Related Agreements.

6.04 WINDING UP. Any provision of this Agreement that expressly or by
implication comes into or remains in force following the termination or
withdrawal from this Agreement shall survive such termination or withdrawal.
The surviving provisions shall include, but shall not be limited to (i) those
provisions necessary to permit the orderly conclusion, or continuation pursuant
to another agreement, of transactions entered into prior to the termination of
or withdrawal from this Agreement, (ii) those provisions necessary to conduct
final billing, collection, and accounting with respect to all matters arising
hereunder, and (iii) the indemnification and limitation of liability provisions
as applicable to periods prior to such termination or withdrawal. The ISO and
the terminating or withdrawing Party or Parties shall have an obligation to
make a good faith effort to agree upon a mutually satisfactory termination or
withdrawal plan. Such plan shall have among its objectives an orderly
termination or withdrawal. The plan shall address, to the extent necessary,
the allocation of any costs directly related to the termination or withdrawal
by the Party or Parties terminating or withdrawing from the Agreement.

6.05 CONFIDENTIALITY.

A. PARTY ACCESS. No Transmission Owner shall have a right hereunder to
receive or review any documents, data or other information of another
Transmission Owner or the ISO supplied pursuant to this Agreement,
including documents, data or other information provided to the ISO, to
the extent such documents, data or information have been designated as
confidential pursuant to the procedures specified in the ISO Tariffs or
to the extent that they have been designated as confidential by such other
Party; provided, however, that a Party may receive and review any composite
documents, data and other information that may be developed based on such
confidential documents, data or information if the composite does not
disclose any individual Party's confidential data or information.

B. REQUIRED DISCLOSURE. Notwithstanding anything in this Section to the
contrary, if a Party is required by applicable law, or in the course of
administrative or judicial proceedings, or subpoena, to disclose
information that is otherwise required to be maintained in confidence
pursuant to this Section, that Party may make disclosure of such
information; provided, however, that as soon as the Party learns of the
disclosure requirement and prior to making such disclosure, that Party
shall notify the affected Party or Parties of the requirement and the terms
thereof and the affected Party or Parties may, at their sole discretion and
cost, assert any challenge to or defense against the disclosure requirement
and the Party shall cooperate with such affected Parties to the maximum
extent practicable to minimize the disclosure of the information consistent
with applicable law. Each Party shall cooperate with the affected Parties
to obtain proprietary or confidential treatment of such information by
the person to whom such information is disclosed prior to any such
disclosure.

6.06 GOVERNING LAW; JURISDICTION. The interpretation and performance of
this Agreement shall be in accordance with and shall be controlled by the laws
of the state of New York as though this Agreement is made and performed
entirely in New York. With respect to any claim or controversy arising from
this Agreement or performance hereunder within the subject matter jurisdiction
of the federal or state courts of the state of New York, the Parties consent to
the exclusive jurisdiction and venue of said courts.

6.07 HEADINGS. The section headings herein are for convenience and reference
only and in no way define or limit the scope of this Agreement or in any way
affect its provisions. Whenever the terms hereto, hereunder, herein or hereof
are used in this Agreement, they shall be construed as referring to this entire
Agreement, rather than to any individual section, subsection or sentence.

6.08 MUTUAL AGREEMENT. Nothing in this Agreement is intended to limit the
Parties' ability to mutually agree upon taking a course of action different
than that provided for herein; provided that doing so will not adversely affect
any other Parties' rights under this Agreement.

6.09 CONTRACT SUPREMACY. In the case of a conflict between the express terms
of this Agreement and the terms of the ISO Agreement, the express terms of this
Agreement shall prevail. In the case of a conflict between the express terms
of this Agreement and the terms of the ISO-NYSRC Agreement, the express terms
of this Agreement shall prevail. In the case of a conflict between the express
terms of this Agreement and the express terms of an ISO Tariff the terms of this
Agreement shall prevail.

6.10 ADDITIONAL REMEDIES. The Parties agree that remedies at law will be
inadequate to protect the interests of the Transmission Owners and that
irreparable damage would occur in the event that any of the provisions of this
Agreement were not performed by the ISO in accordance with their specific terms
or were otherwise breached. Accordingly, it is agreed that the Transmission
Owners, or any Transmission Owner, individually or in conjunction with one or
more other Transmission Owners, shall be entitled to an injunction or
injunctions to prevent breaches of this Agreement or an ISO Tariff by the ISO
and specific performance to enforce specifically the terms and provisions
thereof in any court of the United States or any state having jurisdiction,
this being in addition to any other remedy to which the Transmission Owners
are entitled at law or in equity.

6.11 NO THIRD PARTY RIGHTS. Nothing in this Agreement, express or implied,
is intended to confer on any person, other than the Parties hereto, any rights
or remedies under or by reason of this Agreement.

6.12 NOT PARTNERS. Nothing contained in this Agreement shall be construed
to make the Parties partners or joint venturers or to render any Party liable
for the debts or obligations of any other Party.

6.13 WAIVER. Any waiver at any time of the rights of any Party as to any
default or failure to require strict adherence to any of the terms herein, on
the part of any other Party or Parties to this Agreement or as to any other
matters arising hereunder shall not be deemed a waiver as to any default or
other matter subsequently occurring.

6.14 MODIFICATION. This Agreement is subject to change under Section 205
of the FPA, as that section may be amended or superseded, upon the mutual
written agreement of the Parties. Absent mutual agreement of the Parties, it
is the intent of this Section 6.14 that, to the maximum extent permitted by
law, the terms and conditions set forth in Sections 2.01, 3.03, 3.04, 3.09,
3.10, 3.11, 4.01, 4.02, 5.01, 5.02, 5.03, 5.04, 5.05, 5.06, 6.01, 6.02, 6.09
and 6.14 of this Agreement shall not be subject to change, regardless of
whether such change is sought (a) by the Commission acting sua sponte on behalf
of a Party or third party, (b) by a Party, (c) by a third party, or (d) in any
other manner; subject only to an express finding by FERC that such change is
required under the public interest standard under the Mobile-Sierra doctrine.
Any other provision of this Agreement may be changed pursuant to a filing with
FERC under Section 206 of the FPA and a finding by FERC that such change is
just and reasonable.

6.15 GOOD FAITH RESOLUTION. If cost shifting occurs as a result of FERC's
decision in Central Hudson Gas & Electric Corporation, Docket Nos.
ER97-1523-011, OA97-470-010, and ER97-4234-008, the ISO and the Transmission
Owners will work together in good faith to achieve a fair and equitable
resolution.

6.16 COUNTERPARTS. This Agreement may be executed in any number of
counterparts, no one of which needs to be executed by all of the Parties, and
this Agreement shall be binding upon all the Parties with the same force and
effect as if all the Parties had signed the same document, and each such
signed counterpart shall constitute an original of this Agreement.



IN WITNESS WHEREOF, each of the Parties hereto has caused this Agreement to
be executed in its corporate name by its proper officers as of the date first
written above.

assumptions, as the Committee, in its sole discretion, shall consider
appropriate. Amounts of Other Retirement Income may be taken into account
by the Committee in a form of payment that is different than the form such
Other Retirement Income actually is paid to or on behalf of the
Participant.

1.12 "Participant" means (i) an employee of the Company with the title of
Vice President or above, including those persons designated as Controller
or Treasurer, and (ii) an employee of any Other Employer with the title
of Vice President or above, who is designated by the Committee for
inclusion in the Plan.

1.13 "Plan" means the Niagara Mohawk Supplemental Executive Retirement Plan.

1,14 "Retirement" means the termination of a Participant's employment with the
Company and any Other Employer on or after the date the Participant has
(i) attained age 55, (ii) satisfied the service requirement of Plan
Section 2.1, and (iii) earned a vested benefit under the Basic Plan.

1.15 "Service" means "Service" as defined in the Basic Plan.

1.16 "Social Security Benefit" means the Participant's estimated monthly
primary insurance amount under the Social Security Act as in effect at the
time of separation from Service (projected, if necessary, to age 62 on the
basis of no further earnings after separation from Service). All such
estimates and projections shall be made by the Committee. Earnings for
calendar years prior to the Participant's separation from Service shall be
estimated by applying a salary scale, projected backwards, based upon the
actual change in national average wages as determined by the Social
Security Administration.

Notwithstanding the foregoing, if the Participant shall furnish the
Committee within 12 months from the date of separation from Service (or,
if later, within 12 months from the date the Participant is notified by the
Committee that the Participant is entitled to Plan benefits) with
documentation from the Social Security Administration of the Participant's
Social Security earnings records, the Participant's Social Security Benefit
shall be determined on the basis of his actual Social Security earnings
record for years previously estimated before separation, but only if such
actual Social Security earnings record produces a lower estimated Social
Security Benefit.

Once the Social Security Benefit has been determined, it will be frozen and
not redetermined, subject to the 12 month rule noted above.

1.17 "Spouse" means the person to whom a Participant is legally married as of
his Retirement or death as an Active Participant.

1.18 The masculine gender, where appearing in the Plan, will be deemed to
include the feminine gender, and the singular may include the plural,
unless the context clearly indicates the contrary.

SECTION II
----------

ELIGIBILITY FOR BENEFITS
------------------------

2.1 Each Participant who has completed twenty (20) years of Service with the
Company and any Other Employer, and who has attained at least age 55 at the
time he terminates employment with the Company or any Other Employer, is
eligible to receive a benefit under this Plan upon his Retirement.

Exceptions to the twenty (20) years of Service requirement may be granted
by the Committee.

SECTION III
-----------

AMOUNT AND FORM OF RETIREMENT BENEFIT
-------------------------------------

3.1 The benefit payable at Normal Retirement Date under this Plan will equal
60% of the Participant's Earnings, less any Other Retirement Income as
defined in Plan Section 1.11. In the case of a Participant's Early
Retirement, the benefit payable upon such Early Retirement shall equal the
product of (i) 60% of the Participant's Earnings, times (ii) the applicable
Early Commencement Factor, with the resulting product reduced by the
Participant's Other Retirement Income. As provided in Section 1.11, for
purposes of the Committee's determination of a Participant's Other
Retirement Income, the Committee may make such assumptions, including
interest rate, age at benefit commencement and form of payment assumptions,
as the Committee, in its sole discretion, shall consider appropriate.

3.2 If the Basic Plan Benefit is greater than the Plan benefit for a
Participant or the Participant's surviving Spouse, an additional benefit
will be paid under this Plan to the extent (if any) the Basic Plan Benefit
payable to the Participant or the Participant's surviving Spouse is reduced
by Section 415 of the Internal Revenue Code. In such a case, the Plan
benefit will be recalculated so that the Participant or the Participant's
surviving Spouse shall receive no more in total benefit (from the Basic
Plan plus the Plan) than what the Basic Plan Benefit would have been had
Section 415 of the Internal Revenue Code not applied to the Basic Plan.


SECTION IV
----------

PAYMENT OF RETIREMENT BENEFITS
------------------------------

4.1 Unless paid in an actuarially equivalent lump sum pursuant to Section VI,
benefits payable in accordance with Section III will be paid in monthly
installments commencing as of the end of the month during which payment of
the Participant's Basic Plan Benefit is made or commences. Such benefits
will continue to be paid as of the last day of each succeeding month. The
final payment will be made as of the last day of the month in which the
retired Participant dies. However, any benefits payable to a surviving
Spouse under Section V shall continue to the surviving Spouse for the
period commencing as of the last day of the month following the month in
which the retired Participant or Active Participant dies and ending as of
the last day of the month in which such surviving Spouse dies.

4.2 If a Participant has been receiving benefit payments under provisions of
the separate Long-Term Disability Income Insurance Plan (LTD) of the
Company or any Other Employer, and provided he has reached his Normal
Retirement Date, he will be eligible for benefits as provided under Plan
Sections II and III. These benefits will be based upon the Participant's
Earnings calculated as of the date of the total disability that resulted
in the payment of LTD benefits, rather than Earnings as defined in Section
1.8.

4.3 Except as provided in Section 5.2, no benefits are payable under this Plan
if a Participant terminates employment with the Company or Other Employer
for any reason prior to his Retirement unless otherwise approved by the
Committee. In the event of such approval, benefits shall be paid in
accordance with Section 4.1.

4.4 In the event (i) the Company undergoes a Change in Control (as defined
below), (ii) the Plan is terminated prior to a Change in Control, (iii) the
Company becomes insolvent (i.e., the Company is unable to pay its debts as
they become due), (iv) the Company files for protection under any federal
or state bankruptcy law, or (v) the Company becomes involuntarily subject
to any federal or state bankruptcy proceedings, each Participant (whether
active or retired) or surviving Spouse will have a vested and
nonforfeitable interest in benefits under the Plan determined by
application of the following formula as of the date of such event:

A Participant's or surviving Spouse's vested and nonforfeitable interest
in such benefits under this Section shall be determined by multiplying the
full value of such person's undistributed benefits by a fraction (not
greater than 1/1), the numerator of which is the number of years of the
Participant's Service, and the denominator of which is the total number of
years of Service the Participant is required to complete with the Company
in order to become eligible to receive a distribution of benefits under
this Section.

For purposes of this Section, the term 'Change in Control' shall mean:

(1) The acquisition by any individual, entity or group (within the
meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of
1934, as amended (the "Exchange Act")) (a "Person") of beneficial ownership
(within the meaning of Rule 13d-3 promulgated under the Exchange Act) of
20% or more of either (i) the then outstanding shares of common stock of
the Company (the "Outstanding Company Common Stock") or (ii) the combined
voting power of the then outstanding voting securities of the Company
entitled to vote generally in the election of directors (the "Outstanding
Company Voting Securities"); provided, however, that the following
acquisitions shall not constitute a Change in Control: (i) any acquisition
directly from the Company (excluding an acquisition by virtue of the
exercise of a conversion privilege), (ii) any acquisition by the Company,
(iii) any acquisition by any employee benefit plan (or related trust)
sponsored or maintained by the Company or any corporation controlled by the
Company or (iv) any acquisition by any corporation pursuant to a
reorganization, merger or consolidation, if, following such reorganization,
merger or consolidation, the conditions described in clauses (i), (ii) and
(iii) of subparagraph (3) of this Section 4.4 are satisfied; or

(2) Individuals who, as of April 1, 1999, constitute the Company's Board
of Directors (the "Incumbent Board") cease for any reason to constitute at
least a majority of the Board; provided, however, that any individual
becoming a director subsequent to the date hereof whose election, or
nomination for election by the Company's shareholders, was approved by a
vote of at least a majority of the directors then comprising the Incumbent
Board shall be considered as though such individual were a member of the
Incumbent Board, but excluding, for this purpose, any such individual whose
initial assumption of office occurs as a result of either an actual or
threatened election contest (as such terms are used in Rule 14a-11 of
Regulation 14A promulgated under the Exchange Act) or other actual or
threatened solicitation of proxies or consents by or on behalf of a Person
other than the Board; or

(3) Approval by the shareholders of the Company of a reorganization, merger
or consolidation, in each case, unless, following such reorganization,
merger or consolidation, (i) more than 75% of, respectively, the then
outstanding shares of common stock of the corporation resulting from such
reorganization, merger or consolidation and the combined voting power of
the then outstanding voting securities of such corporation entitled to vote
generally in the election of directors is then beneficially owned, directly
or indirectly, by all or substantially all of the individuals and entities
who were the beneficial owners, respectively, of the Outstanding Company
Common Stock and Outstanding Company Voting Securities immediately prior to
such reorganization, merger or consolidation in substantially the same
proportions as their ownership, immediately prior to such reorganization,
merger or consolidation, of the Outstanding Company Common Stock and
Outstanding Company Voting Securities, as the case may be, (ii) no Person
(excluding the Company, any employee benefit plan (or related trust) of the
Company or such corporation resulting from such reorganization, merger or
consolidation and any Person beneficially owning, immediately prior to such
reorganization, merger or consolidation, directly or indirectly, 20% or
more of the Outstanding Company Common Stock or Outstanding Company Voting
Securities, as the case may be) beneficially owns, directly or indirectly,
20% or more of, respectively, the then outstanding shares of common stock
of the corporation resulting from such reorganization, merger or
consolidation or the combined voting power of the then outstanding voting
securities of such corporation entitled to vote generally in the election
of directors and (iii) at least a majority of the members of the board of
directors of the corporation resulting from such reorganization, merger or
consolidation were members of the Incumbent Board at the time of the
execution of the initial agreement providing for such reorganization,
merger or consolidation; or

(4) Approval by the shareholders of the Company of (i) a complete
liquidation or dissolution of the Company or (ii) the sale or other
disposition of all or substantially all of the assets of the Company or,
on or after April 1, 1999, of Niagara Mohawk Power Corporation, other than
to a corporation, with respect to which following such sale or other
disposition, (A) more than 75% of, respectively, the then outstanding
shares of common stock of such corporation and the combined voting power
of the then outstanding voting securities of such corporation entitled to
vote generally in the election of directors is then beneficially owned,
directly or indirectly, by all or substantially all of the individuals and
entities who were the beneficial owners, respectively, of the Outstanding
Company Common Stock and Outstanding Company Voting Securities immediately
prior to such sale or other disposition in substantially the same
proportion as their ownership, immediately prior to such sale or other
disposition, of the Outstanding Company Common Stock and Outstanding
Company Voting Securities, as the case may be, (B) no Person (excluding
the Company and any employee benefit plan (or related trust) of the Company
or such corporation and any Person beneficially owning, immediately prior
to such sale or other disposition, directly or indirectly, 20% or more of
the Outstanding Company Common Stock or Outstanding Company Voting
Securities, as the case may be) beneficially owns, directly or indirectly,
20% or more of, respectively, the then outstanding shares of common stock
of such corporation and the combined voting power of the then outstanding
voting securities of such corporation entitled to vote generally in the
election of directors and (C) at least a majority of the members of the
board of directors of such corporation were members of the Incumbent Board
at the time of the execution of the initial agreement or action of the
Board providing for such sale or other disposition of assets of the
Company.

4.5 Coincident with, or as soon as practicable after, the occurrence of any
of the events described in clauses (ii) through (v) in the first sentence
of Section 4.4 above, the actuarial present value of each Participant's or
surviving Spouse's benefits (as determined by the actuary engaged by the
Company with respect to the Plan), to the extent vested under Section 4.4
above, shall be paid to such Participant or surviving Spouse in a single
sum distribution, but only to the extent such single sum distribution is
permitted by law.

Notwithstanding any other provisions of this Plan, the completion of the
full distribution required by this Section 4.5 shall terminate all rights
of all persons (whether or not then collecting benefits) to any benefits
under the Plan. No further benefits shall accrue to any person under this
Plan and the Plan shall terminate without any further action by the
Company.

SECTION V
---------

PAYMENT OF SPOUSE'S SURVIVOR BENEFITS
-------------------------------------

5.1 Unless the Participant's Plan benefit is paid to the Participant in an
actuarially equivalent lump sum pursuant to Section VI, commencing as of
the last day of the month following the month in which the retired
Participant dies, the Participant's surviving Spouse will receive the
greater of (i) 50% of the monthly benefit payable to the Participant, or
(ii) the monthly benefit, if any, calculated under Plan Section 3.2

5.2 Commencing at the end of the month following the month in which an
Active Participant dies, the surviving Spouse will receive the monthly
benefit as calculated in Plan Section 5.1 as if the Active Participant
had retired on the first of the month following the month of the Active
Participant's death.

5.3 Notwithstanding the foregoing of this Section V, with respect to a
Participant who has a valid lump sum election pursuant to Section 6.3 of
the Plan in effect on the date of the Participant's death, but who dies
prior to receipt of such lump sum payment, the Participant's surviving
Spouse shall receive the surviving Spouse's monthly benefit described in
Section 5.1 (if any) in an actuarially equivalent lump sum. Actuarially
equivalent lump sums shall be determined by the Committee in accordance
with Section 6.5 of the Plan.

5.4 Notwithstanding the foregoing of this Section V, if a Participant's
benefit under this Plan is paid in a lump sum, no further benefits shall
be paid to or on behalf of the Participant or the Participant's surviving
Spouse pursuant to this Plan.

SECTION VI
----------

OPTIONAL LUMP SUM PAYMENT
-------------------------

6.1 Notwithstanding any other provision of the Plan to the contrary, the
following provisions shall apply with respect to the payment of benefits
under this Plan.

6.2 With respect to a Participant whose benefit payments have not commenced
and whose annual benefit under this Plan equals or exceeds either (x) fifty
percent (50%) of the sum of his annual benefit under this Plan and his
annual benefit under the Basic Plan, or (y) $50,000:

a. the Committee may determine solely in its discretion that such
Participant's (or surviving Spouse's) benefits under this Plan shall
be paid in the form of an actuarially equivalent lump sum; or

b. such Participant may elect payment of his benefit under this Plan in
the form of an actuarially equivalent lump sum, provided, however, that
the Participant has irrevocably elected in writing to receive such lump
sum no later than a date which is both (i) in the calendar year prior
to the Participant's Retirement, and (ii) at least six months prior to
the date of the Participant's Retirement.

6.3 With respect to a Participant (i) whose benefit payments under this Plan
are being paid in monthly installments pursuant to Section 4.1 of the Plan,
and (ii) whose annual benefit under this Plan equals or exceeds either (x)
fifty percent (50%) of the sum of his annual benefit under this Plan and
his annual benefit under the Basic Plan, or (y) $50,000, such Participant
may elect, subject to the written approval of the Committee, to receive a
lump sum payment of the remaining payments due him under the Plan in an
amount equal to 95% of the actuarially equivalent lump sum of such
payments.

6.4 The Committee, in its sole discretion, shall determine the amount of
actuarially equivalent lump sums. For purposes of such determinations, the
Committee may make such assumptions, including interest rate assumptions,
as the Committee, in its sole discretion, shall consider appropriate.


SECTION VII
-----------
MISCELLANEOUS
-------------

7.1 Plan benefits are paid for the Participant's past services with the Company
and any Other Employer (that is, not for consulting or other services that
may be rendered after retirement) and are not subject to forfeiture upon
the Participant's Retirement. To minimize the possibility of future
termination of the Plan for financial reasons, the Company may utilize
certain financing vehicles, including the purchase of policies of
insurance on the lives of Participants under which the Company or a trustee
is named beneficiary; any such insurance policies or other financing
vehicles will be subject to the claims of the general creditors of the
Company. The Board of Directors of the Company may, in its sole
discretion, terminate, suspend or amend the Plan at any time, in whole or
in part; provided, however, that no such termination, suspension or
amendment shall adversely affect a Participant's rights or benefits accrued
under this Plan (with both his Plan benefit and Basic Plan Benefit
determined, for purposes of this Section, on the basis of the Participant's
Earnings averaged for the 36-month period ending on the date of such Plan
termination, suspension or amendment).

7.2 Nothing contained herein will confer upon any Participant the right to
be retained in the service of the Company or any Other Employer, nor will
it interfere with the right of the Company or any Other Employer to
discharge or otherwise deal with Participants without regard to the
existence of this Plan.

7.3 This Plan is unfunded and not tax-qualified, and the Company will make
Plan benefit payments solely on a current disbursement basis.

7.4 To the maximum extent permitted by law, no benefit under this Plan shall
be assignable or subject in any manner to alienation, sale, transfer,
claims of creditors, pledge, attachment or encumbrances of any kind.
Notwithstanding the foregoing, benefits earned and payments made pursuant
to the Plan shall be subject to withholding for income, FICA and other
employee payroll taxes, withholding taxes, or other taxes that the Company
or Other Employer may be required by law to withhold.

7.5 The Committee may adopt rules and regulations to assist in the
administration of the Plan. The Committee also shall have discretionary
authority to construe, interpret and apply all of the terms of this Plan
(including, but not limited to, construing any uncertain or disputed term
or provision, determining questions of fact and/or law, and reviewing any
prior benefit claim determination under the Plan), and to determine the
amount (if any) of each Participant's and surviving Spouse's benefit under
this Plan. The Board of Directors has also delegated to the Committee the
discretionary authority to modify provisions of the Plan in individual
cases. Any exercise of the Committee's authority under this Plan shall be
final and binding.

7.6 Each Participant will be entitled to a copy of this Plan.

7.7 The Plan is established under, and shall be governed and construed
according to, the laws of the State of New York, to the extent such laws
are not preempted by federal law.

The Company has caused this Plan document, which reflects the Plan as
amended and restated effective as of January 1, 1999, to be executed by a
duly authorized officer on this 17th day of December 1999.

AMENDMENT 1
TO THE
NIAGARA MOHAWK POWER CORPORATION
EXCESS BENEFIT PLAN

This sets forth Amendment 1 to the Niagara Mohawk Power Corporation Excess

as follows:

"Committee" means, effective March 17, 1999, the Compensation and Succession
Committee of the Board of Directors of Niagara Mohawk Holdings, Inc. which

participates in this Plan with the consent of Niagara Mohawk Holdings, Inc.
shall hereinafter be referred to as a "Participating Employer").
Notwithstanding the foregoing, the term "Company" means Niagara Mohawk

title of any employee benefit plan that was in existence on January 1, 1999
and with respect to which a post-1998 event is being referred to, such title
shall be modified by deleting the reference to "Niagara Mohawk Power
Corporation" and is inserting in its place a reference to "Niagara Mohawk."

5. Effective March 17, 1999, the fourth sentence of Section 3.1 of the Plan
shall be restated as follows:

The Board of Directors of Niagara Mohawk Holdings, Inc. may, in its sole
discretion, terminate, suspend or amend the Plan at any time or from time
to time, in whole or in part; provided, however, that no such termination,
suspension or amendment shall adversely affect a Participant's rights or
