PART I

Item 1. Business.

GENERAL

UIL Holdings Corporation (UIL Holdings) is the parent holding company for The
United Illuminating Company (UI) and United Resources, Inc (URI) and is not
itself an operating company. This holding company structure became effective on
July 20, 2000 as a result of the corporate restructuring of UI and its direct
and indirect non-regulated subsidiaries. All of UI's interests in all of its
direct and indirect non-regulated subsidiaries have been transferred to UIL
Holdings and, to the extent new businesses are subsequently acquired or
commenced, UIL Holdings expects they will be owned by UIL Holdings. UIL Holdings
is headquartered in New Haven, Connecticut, where its senior management
maintains offices and is responsible for overall planning, operating and
financial functions. UIL Holdings is an exempt public utility holding company
under the provisions of the Public Utility Holding Company Act of 1935.

THE UNITED ILLUMINATING COMPANY

UI is a regulated operating electric public utility established in 1899. It is
engaged principally in the purchase, transmission, distribution and sale of
electricity for residential, commercial and industrial purposes in a service
area of about 335 square miles in the southwestern part of the State of
Connecticut. The population of this area is approximately 704,000, which
represents approximately 21% of the population of the State. The service area,
largely urban and suburban in character, includes the principal cities of
Bridgeport (population approximately 137,000) and New Haven (population
approximately 124,000) and their surrounding areas. Situated in the service area
are retail trade and service centers, as well as large and small industries
producing a wide variety of products, including helicopters and other
transportation equipment, electrical equipment, chemicals and pharmaceuticals.
Of UI's 2000 retail electric revenues, approximately 42% were derived from
residential sales, 40% from commercial sales, 16% from industrial sales and 2%
from other sales.

For a description of the changes in UI's electric public utility business that
have resulted from Connecticut's enactment, in 1998, of Public Act 98-28 (the
Restructuring Act), see PART II, Item 8, "Financial Statements and Supplementary
Data - Notes to Consolidated Financial Statements - Note (C), Rate-Regulated
Regulatory Proceedings."

FRANCHISES

Subject to the power of alteration, amendment or repeal by the Connecticut
legislature, and subject to certain approvals, permits and consents of public
authorities and others prescribed by statute, UI has valid franchises to engage
in the purchase, transmission, distribution and sale of electricity in the area
served by it, the right to erect and maintain certain facilities on public
highways and grounds, and the power of eminent domain.

REGULATION

UI is subject to regulation by the Connecticut Department of Public Utility
Control (DPUC), which has jurisdiction with respect to, among other things,
retail electric service rates, accounting procedures, certain dispositions of
property and plant, mergers and consolidations, the issuance of securities,
certain standards of service, management efficiency, operation and construction,
and the location and construction of certain electric facilities. The DPUC
consists of five Commissioners, appointed by the Governor of Connecticut with
the advice and consent of both houses of the Connecticut legislature.

The location and construction of certain electric facilities is also subject to
regulation by the Connecticut Siting Council with respect to environmental
compatibility and public need. See "Environmental Regulation."

UI is a "public utility" within the meaning of Part II of the Federal Power Act
and is subject to regulation by the Federal Energy Regulatory Commission, which
has jurisdiction with respect to interconnection and coordination of


- 4 -


facilities, wholesale electric service rates and accounting procedures, among
other things. See "Arrangements with Other Utilities."

In connection with ownership and leasehold interests in Seabrook Unit 1 and
Millstone Unit 3, UI is a holder of licenses under the Atomic Energy Act of
1954, as amended, and, as such, is subject to the jurisdiction of the United
States Nuclear Regulatory Commission (NRC), which has broad regulatory and
supervisory jurisdiction with respect to the construction and operation of
nuclear reactors, including matters of public health and safety, financial
qualifications, antitrust considerations and environmental impact. Connecticut
Yankee Atomic Power Company (Connecticut Yankee), in which UI has a 9.5% common
stock ownership share, is also subject to this NRC regulatory and supervisory
jurisdiction. See Item 2, "Properties - The United Illuminating Company -
Nuclear Generation."

UI is subject to the jurisdiction of the New Hampshire Public Utilities
Commission for limited purposes in connection with its 17.5% ownership and
leasehold interests in Seabrook Unit 1.

RATES

UI's retail electric service rates are subject to regulation by the DPUC.

UI's present general retail rate structure consists of various rate and service
classifications covering residential, commercial, industrial and street lighting
services.

Utilities are entitled by Connecticut law to charge rates that are sufficient to
allow them an opportunity to cover their reasonable operating and capital costs,
to attract needed capital and maintain their financial integrity, while also
protecting relevant public interests.

See PART II, Item 8, "Financial Statements and Supplementary Data - Notes to
Consolidated Financial Statements - Note (C), Rate-Regulated Regulatory
Proceedings" regarding the five-year incentive rate regulation plan, for the
years 1997 through 2001, that is currently in effect for UI and the standard
offer rates established by the DPUC pursuant to the Restructuring Act.

POWER SUPPLY ARRANGEMENTS

Under the Restructuring Act, all Connecticut electricity customers are able to
choose their power supply providers. Until January 1, 2004, UI is required to
offer full retail service to its customers under a regulated "standard offer"
rate and is also required to be the power supply provider to each customer who
does not choose an alternate power supply provider, even though UI is no longer
in the business of retail power generation. UI is also required under the
Restructuring Act to provide back-up power supply service to customers whose
alternate power supply provider fails to provide power supply services for
reasons other than the customers' failure to pay for such services.

On December 28, 1999, UI entered into a series of agreements with Enron Power
Marketing, Inc. (EPMI), a subsidiary of Enron Corp., Houston, Texas, for the
supply of all of the power needed by UI to meet its standard offer obligations
until the end of the four-year standard offer period and the power needed to
serve UI's special contract customers for the remaining contract terms. The
agreements also provide for the sale to EPMI of UI's entitlements under all of
its wholesale purchased power agreements (PPAs). However, unless or until a PPA
is terminated or formally assigned to EPMI, UI remains legally liable to pay the
applicable power supplier all amounts due under the PPA. The agreements with
EPMI also include a financially settled contract for differences related to
certain call rights of EPMI and put rights of UI with respect to UI's
entitlements in Seabrook Unit 1 and in Millstone Unit 3, and UI's provision to
EPMI of certain ancillary products and services associated with those nuclear
entitlements, which provisions terminate at the earlier of December 31, 2003 or
the date that UI sells its nuclear interests. The agreements do not restrict
UI's right to sell to third parties UI's ownership interests in those nuclear
generation units or the generated energy actually attributable to its ownership
interests.

If the generation resources available to UI's wholesale suppliers become
inadequate to meet its customer service obligations, UI expects to be able to
reduce the load on its system by the implementation of demand-side


- 5 -


management programs, to acquire other demand-side and supply-side resources,
and/or to purchase capacity from other utilities or from the installed
capability spot market, as necessary. However, because the generation and
transmission systems of the major New England utilities, including UI, are
operated as if they were a single system, the ability of UI to meet its customer
service obligations is and will be dependent on the ability of the region's
generation and transmission systems to meet the region's load.

ARRANGEMENTS WITH OTHER UTILITIES

NEW ENGLAND POWER POOL

UI, in cooperation with other privately and publicly owned New England electric
utilities, established the New England Power Pool (NEPOOL) in 1971. NEPOOL was
formed to assure reliable operation of the bulk power system in the most
economic manner for the region. It has achieved these objectives through central
dispatching of all generation facilities owned by its members and through
coordination of the activities of the members that can have significant
inter-utility impacts. NEPOOL is governed by an agreement (NEPOOL Agreement)
that is filed with the Federal Energy Regulatory Commission (FERC); and its
provisions are subject to continuing FERC jurisdiction.

Because of evolving industry-wide changes, NEPOOL has been restructured. Its
membership has been broadened to cover all entities engaged in the electricity
business in New England, including power marketers and brokers, independent
power producers and load aggregators. An independent entity, ISO New England,
Inc. (ISO-NE), has the responsibility for the operation of the regional bulk
power system, so that the regional bulk power system will continue to be
operated both in accordance with the NEPOOL objectives and free of any adverse
impact on competition in the wholesale power markets, where various energy and
capacity products are traded in open competition among all participants.
Amendments to the NEPOOL Agreement establishing the markets were filed with and
have been approved by the FERC, and the markets became operational on May 1,
1999. There will be further substantial changes to the NEPOOL power markets,
including implementation of a transmission congestion management system (CMS)
and a multi-settlement system (MSS). CMS will help to optimize the use of the
existing transmission system and will help to ensure the efficient siting of new
generation and transmission resources. MSS will significantly reduce incentives
for participants to strategically manipulate purchase and sale bids. CMS is
scheduled to become functional in the spring of 2002. MSS is expected to go into
effect one year later.

On January 16, 2001, the New England transmission owners, including UI, and
ISO-NE, submitted a joint compliance filing with the FERC, pursuant to the
FERC's Order No. 2000, proposing a regional transmission organization for the
New England region. The proposed regional transmission organization would
consist of the not-for-profit independent system operator (ISO-NE) working in
concert with a for-profit independent transmission company, of which UI intends
to be a part. The system operator will be responsible for the real-time
operation of the electric system, short-term reliability, and administrative
functions associated with the electricity markets; the independent transmission
company will be primarily responsible for managing the transmission assets,
including system maintenance, expansion and long-term reliability.

NEW ENGLAND TRANSMISSION GRID

Under other agreements related to UI's participation in the ownership of
Seabrook Unit 1 and Millstone Unit 3, UI contributes to the financial support of
certain 345 kilovolt transmission facilities that are a part of the New England
transmission grid.

HYDRO-QUEBEC

UI is a participant in the Hydro-Quebec transmission intertie facility linking
New England and Quebec, Canada. Phase I of this facility, which became
operational in 1986 and in which UI has a 5.45% participating share, has a 690
megawatt equivalent generation capacity value; and Phase II, in which UI has a
5.45% participating share, increased the equivalent generation capacity value of
the intertie from 690 megawatts to a maximum of 2000


- 6 -


megawatts in 1991. UI is obligated to furnish a guarantee for its participating
share of the debt financing for the Phase II facility. As of December 31, 2000,
UI's guarantee liability for this debt was approximately $5.6 million.

LONG ISLAND CABLE PROJECT

United Capital Investments (UCI), a wholly-owned subsidiary of United Resources,
Inc., has a 25% interest in a merchant electric transmission line project that
proposes to install, own and operate a 330-megawatt transmission line connecting
Connecticut and Long Island under Long Island Sound. UCI is obligated to furnish
a direct guarantee by means of a letter of credit for its participating share of
the debt financing of the project. Under separate agreement, UIL Holdings is an
indirect guarantor of the obligation of UCI. As of December 31, 2000, UCI's
guarantee liability for this debt was approximately $7.7 million.

UNITED RESOURCES, INC.

URI serves as the parent corporation for several non-regulated businesses, each
of which is incorporated separately to participate in business ventures that
will provide long-term rewards to UIL Holdings' shareowners. URI, which is not
itself an operating company, has four wholly-owned subsidiaries:

AMERICAN PAYMENT SYSTEMS, INC. (APS) is the largest vendor in the nation for
walk-in payment of utility bills. APS manages a national network of agents for
the processing of bill payments made by customers of UI and other companies. It
recruits and manages agents who collect payments for APS clients that include
major utility and telecommunications companies such as Entergy, Southern
California Edison, AT&T, and Ameritech. APS collects and forwards payment and
other information electronically to its clients, and sweeps agent accounts daily
for deposit in the clients' bank accounts. It processes all critical data
in-house in Hamden, Connecticut.

XCELECOM, INC. (Xcelecom, formerly known as Precision Power, Inc.) and its
subsidiaries, provide general and specialty electrical and voice-data-video
design, construction, systems integration and services in regional markets of
the Northeastern United States. The Xcelecom group currently includes Allan

and Signal, Ltd., of Connecticut. Xcelecom also owns and operates heating and
cooling energy centers through its Thermal Energies, Inc. subsidiary, providing
heating and cooling services to two of New Haven, Connecticut's largest office
and government complexes.

UNITED CAPITAL INVESTMENTS, INC. (UCI) and its subsidiaries invest in business
ventures that are expected to earn above-average returns. Its investments
include:

o LONG ISLAND CABLE PROJECT - UCI has a 25% interest in a merchant electric
transmission line project that proposes to install, own and operate a
330-megawatt transmission line connecting Connecticut and Long Island under

established for the benefit of an institutional investor a portion of UI's
17.5% ownership interest in this unit. This portion of the unit is subject
to the lien of a first mortgage granted by the owner trustee.

UI is in the process of selling all of its interests in Millstone Unit 3 and
Seabrook Unit 1, in compliance with Connecticut's Restructuring Act. See PART
II, Item 8, "Financial Statements and Supplementary Data - Notes to Consolidated
Financial Statements - Note (C), Rate-Regulated Regulatory Proceedings."

TRANSMISSION AND DISTRIBUTION PLANT

The transmission lines of UI consist of approximately 102 circuit miles of
overhead lines and approximately 17 circuit miles of underground lines, all
operated at 345 KV or 115 KV and located within or immediately adjacent to the
territory served by UI. These transmission lines interconnect electric
generation facilities in Bridgeport and New Haven and are part of the New
England transmission grid through connections with the transmission lines of The
Connecticut Light and Power Company. A major portion of UI's transmission lines
is constructed on railroad


- 8 -


right-of-way pursuant to two Transmission Line Agreements. One of the Agreements
expired in May 2000 and UI expects to extend this Agreement. The other Agreement
has been extended to May 2040.

UI owns and operates 25 bulk electric supply substations with a capacity of
1,756,300 KVA and 32 distribution substations with a capacity of 154,770 KVA. UI
has 3,170 pole-line miles of overhead distribution lines and 130 conduit-bank
miles of underground distribution lines.

See PART II, Item 8, "Financial Statements and Supplementary Data - Notes to
Consolidated Financial Statements - Note (L), Commitments and Contingencies -
Capital Expenditure Program" concerning the estimated cost of additions to UI's
transmission and distribution facilities.

NUCLEAR GENERATION

Seabrook Unit 1 is a nuclear generating unit located in Seabrook, New Hampshire,
that is jointly owned by UI and ten other New England electric utility entities.
Millstone Unit 3 is a nuclear generating unit located in Waterford, Connecticut,
that is jointly owned by UI and twelve other New England electric utility
entities. UI holds ownership and leasehold interests totalling 17.5% (203.18
megawatts) in Seabrook Unit 1, and a 3.685% (42.21 megawatts) ownership interest
in Millstone Unit 3. UI also owns 9.5% of the common stock of Connecticut
Yankee, and was entitled to an equivalent percentage (53.21 megawatts) of the
generating capability of the Connecticut Yankee Unit prior to its retirement
from commercial operation on December 4, 1996.

Seabrook Unit 1 commenced commercial operation in June of 1990, pursuant to an
operating license issued by the NRC, which will expire in 2026. It is jointly
owned by eleven New England electric utility entities, including UI, and is
operated by a service company subsidiary of Northeast Utilities (NU). Through
December 31, 2000, Seabrook Unit 1 has operated at a lifetime capacity factor of
80.3%.

Millstone Unit 3 commenced commercial operation in April of 1986, pursuant to a
40-year operating license issued by the NRC. It is jointly owned by thirteen New
England electric utility entities, including UI, and is operated by another
service company subsidiary of NU. Through December 31, 2000, Millstone Unit 3
has operated at a lifetime capacity factor of 63.3%.

UI is in the process of selling all of its interests in Millstone Unit 3 and
Seabrook Unit 1, in compliance with Connecticut's Restructuring Act. See PART
II, Item 8, "Financial Statements and Supplementary Data - Notes to Consolidated
Financial Statements - Note (C), Rate-Regulated Regulatory Proceedings."

The Connecticut Yankee Unit commenced commercial operation in January of 1968,
pursuant to a 40-year operating license issued by the NRC. It is owned, through
ownership of Connecticut Yankee's common stock, by ten New England electric
utilities, including UI. In July of 1996, the Connecticut Yankee Unit was taken
out of service following an engineering evaluation, and an economic study by the
owners, comparing the costs of continuing to operate the Connecticut Yankee Unit
over the remaining period of its operating license to the costs of shutting down
the unit permanently and incurring replacement power costs for the same period,
resulted in a decision, in December of 1996, by the Board of Directors of
Connecticut Yankee to retire the Connecticut Yankee Unit from commercial
operation.

The power purchase contract under which UI purchased its 9.5% entitlement to the
Connecticut Yankee Unit's power output permits Connecticut Yankee to recover
9.5% of all of its costs from UI. In December of 1996, Connecticut Yankee filed
decommissioning cost estimates and amendments to the power contracts with its
owners with the Federal Energy Regulatory Commission (FERC). Based on regulatory
precedent, this filing requested confirmation that Connecticut Yankee will
continue to collect from its owners its decommissioning costs, the unrecovered
investment in the Connecticut Yankee Unit and other costs associated with the
permanent shutdown of the Connecticut Yankee Unit. On April 7, 2000, Connecticut
Yankee reached a settlement agreement with the Connecticut Department of Public
Utility Control (DPUC) and the Connecticut Office of Consumer Counsel (two of
the intervenors in the FERC proceeding). This agreement was submitted to the
FERC, which approved it in all respects on July 26, 2000; and it became
effective on August 1, 2000. The agreement allows Connecticut Yankee to earn a
return on equity of 6% and


- 9 -


stipulates a new decommissioning cost estimate for the Connecticut Yankee Unit
for purposes of FERC-approved decommissioning cost collections by Connecticut
Yankee through the power contracts with the unit's owners.

GENERAL CONSIDERATIONS

Seabrook Unit 1, Millstone Unit 3 and the Connecticut Yankee Unit are each
subject to the licensing requirements and jurisdiction of the Nuclear Regulatory
Commission (NRC) under the Atomic Energy Act of 1954, as amended, and to a
variety of other state and federal requirements.

The NRC regularly conducts generic reviews of numerous technical issues, ranging
from seismic design to education and fitness for duty requirements for licensed
plant operators. The outcome of reviews that are currently pending, and the ways
in which the nuclear generating units in which UI has interests may be affected
by these reviews, cannot be determined; and the cost of complying with any new
requirements that might result from the reviews cannot be estimated. However,
such costs could be substantial.

Additional capital expenditures and increased operating costs for nuclear
generating units may result from modifications of these facilities or their
operating procedures required by the NRC, or from actions taken by other joint
owners or companies having entitlements in the units. Some equipment
modifications have required and may in the future require shutdowns or deratings
of generating units that would not otherwise be necessary and that result in
additional costs. The amounts of additional capital expenditures and increased
costs cannot now be predicted, but they have been and may in the future be
substantial.

NUCLEAR FUEL

Generally, the supply of fuel for nuclear generating units involves the mining
and milling of uranium ore to uranium concentrates, the conversion of uranium
concentrates to uranium hexafluoride, enrichment of that gas and fabrication of
the enriched hexafluoride into usable fuel assemblies.

After a region (approximately 1/3 to 1/2 of the nuclear fuel assemblies in the
reactor at any time) of spent fuel is removed from a nuclear reactor, it is
placed in temporary storage in a spent fuel pool at the nuclear station for
cooling and ultimately is expected to be transported to a permanent storage
site, which has yet to be determined. See PART II, Item 8, "Financial Statements
and Supplementary Data - Notes to Consolidated Financial Statements - Note (M),
Nuclear Fuel Disposal and Nuclear Plant Decommissioning. "

Based on information furnished by the utility responsible for the operation of
the units in which UI is participating, there are outstanding contracts that
cover uranium concentrate purchases for Millstone Unit 3 and Seabrook Unit 1
through 2003. In addition, there are outstanding contracts, to the extent
indicated below, for conversion, enrichment and fabrication services for these
units extending through the following years:

CONVERSION TO
HEXAFLUORIDE ENRICHMENT FABRICATION

Millstone Unit 3 2003 2002 2008
Seabrook Unit 1 2003 2007 2008

INSURANCE REQUIREMENTS

The Price-Anderson Act, currently extended through August 1, 2002, limits public
liability resulting from a single incident at a nuclear power plant. The first
$200 million of liability coverage is provided by purchasing the maximum amount
of commercially available insurance. Additional liability coverage will be
provided by an assessment of up to $83.9 million per incident, levied on each of
the nuclear units licensed to operate in the United States, subject to a maximum
assessment of $10 million per incident per nuclear unit in any year. In
addition, if the sum of all public liability claims and legal costs resulting
from any nuclear incident exceeds the maximum amount of financial protection,
each reactor operator can be assessed an additional 5% of $83.9 million, or $4.2
million. The maximum assessment is adjusted at least every five years to reflect
the impact of inflation. With respect to each of the two


- 10 -


operating nuclear generating units in which UI has an interest, UI will be
obligated to pay its ownership and/or leasehold share of any statutory
assessment resulting from a nuclear incident at any nuclear generating unit.
Based on its interests in these nuclear generating units, UI estimates its
maximum liability would be $17.8 million per incident. However, any assessment
would be limited to $2.1 million per incident per year.

The Nuclear Regulatory Commission requires each operating nuclear generating
unit to obtain property insurance coverage in a minimum amount of $1.06 billion
and to establish a system of prioritized use of the insurance proceeds in the
event of a nuclear incident. The system requires that the first $1.06 billion of
insurance proceeds be used to stabilize the nuclear reactor to prevent any
significant risk to public health and safety and then for decontamination and
cleanup operations. Only following completion of these tasks would the balance,
if any, of the segregated insurance proceeds become available to the unit's
owners. For each of the two operating nuclear generating units in which UI has
an interest, UI is required to pay its ownership and/or leasehold share of the
cost of purchasing such insurance. Although each of these units has purchased
$2.75 billion of property insurance coverage, representing the limits of
coverage currently available from conventional nuclear insurance pools, the cost
of a nuclear incident could exceed available insurance proceeds. Under those
circumstances, the nuclear insurance pools that provide this coverage may levy
assessments against the insured owner companies if pool losses exceed the
accumulated funds available to the pool. The maximum potential assessments
against UI with respect to losses occurring during current policy years are
approximately $2.4 million.

WASTE DISPOSAL AND DECOMMISSIONING

See PART II, Item 8, "Financial Statements and Supplementary Data - Notes to
Consolidated Financial Statements - Note (M), Nuclear Fuel Disposal and Nuclear
Plant Decommissioning" regarding the disposal of spent nuclear fuel and
high-level and low-level radioactive wastes in connection with the operation and
decommissioning of Seabrook Unit 1, Millstone Unit 3 and the Connecticut Yankee
Unit.

ENVIRONMENTAL REGULATION

The National Environmental Policy Act requires that detailed statements of the
environmental effect of UI's facilities be prepared in connection with the
issuance of various federal permits and licenses, some of which are described
below. Federal agencies are required by that Act to make an independent
environmental evaluation of the facilities as part of their actions during
proceedings with respect to these permits and licenses.

Under the federal Toxic Substances Control Act (TSCA), the Environmental
Protection Agency (EPA) has issued regulations that control the use and disposal
of polychlorinated biphenyls (PCBs). PCBs had been widely used as insulating
fluids in many electric utility transformers and capacitors manufactured before
TSCA prohibited any further manufacture of such PCB equipment. Fluids with a
concentration of PCBs higher than 500 parts per million and materials (such as
electrical capacitors) that contain such fluids must be disposed of through
burning in high temperature incinerators approved by the EPA. Solid wastes
containing PCBs must be disposed of in either secure chemical waste landfills or
in high-efficiency incinerators. In response to EPA regulations, UI has phased
out the use of certain PCB capacitors and has tested all UI-owned transformers
located inside customer-owned buildings and replaced all transformers found to
have fluids with detectable levels of PCBs (higher than 1 part per million) with
transformers that have no detectable PCBs. Presently, no transformers having
fluids with levels of PCBs higher than 500 parts per million are known by UI to
remain in service in its system, except at one generating station. Compliance
with TSCA regulations has necessitated substantial capital and operational
expenditures by UI, and such expenditures may continue to be required in the
future, although their magnitude cannot now be estimated.

Under the federal Resource Conservation and Recovery Act (RCRA), the generation,
transportation, treatment, storage and disposal of hazardous wastes are subject
to regulations adopted by the EPA. Connecticut has adopted state regulations
that parallel RCRA regulations but are more stringent in some respects. UI has
complied with the notification and application requirements of present
regulations, and the procedures by which UI handles, stores, treats and disposes
of hazardous waste products have been revised, where necessary, to comply with
these regulations.

UI has sold its Bridgeport Harbor Station and New Haven Harbor Station
generating plants in compliance with Connecticut's electric utility industry
restructuring legislation. Environmental assessments performed in connection


- 11 -


with the marketing of these plants indicated that substantial remediation
expenditures will be required in order to bring the plant sites into compliance
with applicable Connecticut minimum standards following their sale. The
purchaser of the plants undertook liability for payment of any remediation
required with respect to the purchased assets. However, UI will be responsible
for remediation of the portions of the plant sites that it has retained, and no
estimate of the potential costs is available.

UI has estimated that the total cost of decontaminating and demolishing its
Steel Point Station and completing requisite environmental remediation of the
site will be approximately $11.3 million, of which approximately $8.7 million
had been incurred as of December 31, 2000, and that the value of the property
following remediation will not exceed $6.0 million. As a result of a 1992 DPUC
retail rate decision, beginning January 1, 1993, UI has been recovering through
retail rates $1.075 million of the remediation costs per year. The remediation
costs, property value and recovery from customers will be subject to true-up in
UI's next retail rate proceeding based on actual remediation costs and actual
gain on UI's disposition of the property.

UI has begun replacing the bulkhead surrounding a site, bordering the Mill River
in New Haven, that contains transmission facilities and deactivated generation
facilities, at an estimated cost of $13.5 million. Of this amount, $4.2 million
represents the portion of the costs to protect UI's transmission facilities and
will be capitalized as plant in service. The remaining estimated cost of $9.3
million was expensed in 1999. UI has conveyed to an unaffiliated entity,
Quinnipiac Energy LLC (QE), this entire site, reserving to UI permanent
easements for the operation of its transmission facilities on the site. QE will
complete the bulkhead replacement project at UI's expense. UI has also funded
61% (approximately $1.2 million) of the environmental remediation costs that
will be incurred by QE to bring the site into compliance with applicable
Connecticut minimum standards. QE intends to reactivate the generation
facilities on the site as a merchant electric generating plant.

RCRA also regulates underground tanks storing petroleum products or hazardous
substances, and Connecticut has adopted state regulations governing underground
tanks storing petroleum and petroleum products that, in some respects, are more
stringent than the federal requirements. UI currently owns 8 underground storage
tanks, which are used primarily for gasoline and fuel oil, that are subject to
these regulations. A testing program has been installed to detect leakage from
any of these tanks, and substantial costs may be incurred for future actions
taken to prevent tanks from leaking, to remedy any contamination of groundwater,
and to modify, remove and/or replace older tanks in compliance with federal and
state regulations.

The owner of a parcel of property in Derby, Connecticut, has notified UI that
the owner is remediating soil contamination of the property by fuel oil, which
contamination the owner has asserted resulted from activities conducted on the
property when it was owned by UI during the period 1961 to 1976. Based on its
own investigation to date, UI has advised the owner that UI has no
responsibility for the alleged soil contamination. The Connecticut Department of
Environmental Protection is remediating a migration of fuel oil contamination
from a neighboring parcel of property into the adjacent Housatonic River. If UI
or regulatory agencies determine that UI is responsible for the costs of these
remediation activities, UI may experience substantial costs, although no
estimate of potential costs is available.

In the past, UI has disposed of residues from operations at landfills, as most
other industries have done. In recent years it has been determined that such
disposal practices, under certain circumstances, can cause groundwater
contamination. Although UI has no knowledge of the existence of any such
contamination, if UI or regulatory agencies determine that remedial actions must
be taken in relation to past disposal practices, UI may experience substantial
costs.

Connecticut statutes prohibit the commencement of construction or reconstruction
of electric transmission facilities, or modification of such facilities, unless
the Connecticut Siting Council has issued a certificate of environmental
compatibility and public need or a declaratory ruling that no certificate is
required because the facility or modification will not have a substantial
adverse environmental effect.

In complying with existing environmental statutes and regulations and further
developments in these and other areas of environmental concern, including
legislation and studies in the fields of water and air quality, hazardous waste
handling and disposal, toxic substances, and electric and magnetic fields, UI
may incur substantial capital expenditures for


- 12 -


equipment modifications and additions, monitoring equipment and recording
devices, and it may incur additional operating expenses. Litigation expenditures
may also increase as a result of scientific investigations, and speculation and
debate, concerning the possibility of harmful health effects of electric and
magnetic fields. The total amount of these expenditures is not now determinable.

wholly-owned subsidiary of UIL Holdings and each share of UI's issued and
outstanding Common Stock was automatically converted into a share of UIL
Holdings Common Stock. This Common Stock has traded on the New York Stock
Exchange since 1971. The high and low sale prices during 2000 and 1999 were as
follows:

2000 SALE PRICE 1999 SALE PRICE

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


MAJOR INFLUENCES ON FINANCIAL CONDITION

UIL Holdings' financial condition will continue to be dependent on the level of
UI's electric utility retail sales and UI's ability to control expenses, as well
as on the performance of the businesses of UIL Holdings' non-regulated
subsidiaries. The two primary factors that affect electric utility sales volume
are economic conditions and weather. The principal factors affecting the
financial condition of APS and Xcelecom are the pace of technological changes,
competition and risks related to the management of growth, including, in the
case of Xcelecom, acquisition financing and integration.

UIL Holdings' financial status and financing capability will continue to be
sensitive to many other factors, including conditions in the securities markets,
economic conditions, interest rates, the level of income and cash flow of UIL
Holdings' subsidiaries, and legislative and regulatory developments, including
the cost of compliance with increasingly stringent environmental legislation and
regulations.

On December 31, 1996, the Connecticut Department of Public Utility Control
(DPUC) completed a financial and operational review of UI and ordered a
five-year incentive regulation plan for the years 1997 through 2001 (the Rate
Plan). The Rate Plan accelerates the amortization and recovery of unspecified
assets during 1999-2001 if UI's common equity return on regulated utility
investment exceeds 10.5% after recording the amortization. UI's authorized
return on regulated utility common equity during the period is 11.5%. Earnings
above 11.5%, on an annual basis, are utilized one-third for customer price
reductions, one-third to increase amortization of assets, and one-third retained
as earnings.

The Rate Plan included a provision that it could be reopened and modified upon
the enactment of electric utility restructuring legislation in Connecticut. On
October 1, 1999, the DPUC issued a decision establishing UI's standard offer
customer rates, commencing January 1, 2000, at a level 10% below 1996 rates, as
directed by the Restructuring Act described in detail below. These standard
offer customer rates supersede the rates that were included in the Rate Plan.
The decision also reduced the required amount of accelerated amortization in
2000 and 2001. Under this 1999 decision, all other components of the 1996 Rate
Plan are expected to remain in effect through 2001. The Connecticut Office of
Consumer Counsel (OCC), the statutory representative of consumer interests in
public utility matters, appealed the DPUC's standard offer decision to the
Connecticut Superior Court, challenging the DPUC's determination of UI's average
prices in 1996 rates from which a 10% reduction is required by the Restructuring
Act. On February 22, 2001, the Superior Court dismissed the OCC's appeal from
the DPUC's decision; but UI is unable to predict, at this time, whether the OCC
will appeal from the Superior Court's decision to the Connecticut Appellate
Court.

On February 13, 2001, the Connecticut Attorney General and the OCC petitioned
the DPUC to initiate a proceeding and hold a hearing concerning the need to
decrease UI's rates by reason of UI' s having earned a return on regulated
common equity more than 1% above the authorized level of 11.5% for at least six
consecutive months. UI believes that a hearing would confirm that UI has
complied with the DPUC-ordered earnings sharing mechanism in UI's rate plan; and
it will contest vigorously any arguments for a rate decrease.

In April 1998, Connecticut enacted Public Act 98-28 (the Restructuring Act), a
massive and complex statute designed to restructure the State's regulated
electric utility industry. As a result of the Restructuring Act, the business of
generating and selling electricity directly to consumers has been opened to
competition. These business activities are separated from the business of
delivering electricity to consumers, also known as the transmission and
distribution business. The business of delivering electricity remains with the
incumbent franchised utility companies (including UI) which continue to be
regulated by the DPUC as Distribution Companies.

Under the Restructuring Act, all of UI's customers are able to choose their
power supply providers. Until January 1, 2004, UI is required to offer full
"standard offer" electric service, under regulated rates, to all customers who
do not choose alternate power supply providers. The standard offer rates must be
at least 10% below the average prices in


- 18 -


1996. Under current regulatory provisions, UI's financial condition is not
affected materially by whether customers choose alternate suppliers to UI's
standard offer electric service.

On December 28, 1999, UI and Enron Power Marketing, Inc. (EPMI) entered into a
Wholesale Power Supply Agreement, a PPA Entitlements Transfer Agreement and
related agreements documenting a four-year standard offer power supply
arrangement and the assumption of all of UI's long-term purchased power
agreements, effective January 1, 2000. Under these agreements, EPMI supplies the
generation services needed by UI to meet its standard offer obligations for the
four-year standard offer period at a fixed price. The agreements with EPMI also
include a financially settled contract for differences related to certain call
rights of EPMI and put rights of UI with respect to UI's entitlements in
Seabrook Unit 1 and in Millstone Unit 3, and UI's provision to EPMI of certain
ancillary products and services associated with those nuclear entitlements,
which provisions terminate at the earlier of December 31, 2003 or the date that
UI sells its nuclear interests. The agreements do not restrict UI's right to
sell to third parties UI's ownership interests in those nuclear generation units
or the generated energy actually attributable to its ownership interests.

The Restructuring Act requires that UI must attempt to divest its ownership
interests in its nuclear-fueled power plants prior to 2004 in order to recover
any stranded costs associated with its power plants. On October 1, 1998, in its
"unbundling plan" filing with the DPUC under the Restructuring Act, and in other
regulatory dockets, UI stated that it plans to divest its nuclear generation
ownership interests (17.5% of Seabrook Unit 1 in New Hampshire and 3.685% of
Millstone Station Unit 3 in Connecticut) by the end of 2003, in accordance with
the Restructuring Act. On April 19, 2000, the DPUC approved UI's plan for
divesting its ownership interest in Millstone Unit 3 by participating in an
auction process for all three of the generating units at Millstone Station,
which was concluded on August 7, 2000, when Dominion Resources, Inc. agreed to
purchase Millstone Units 1 and 2, and 93.47% of Millstone Unit 3 for $1.298
billion. The purchase price agreed to for UI's ownership interest in Unit 3,
which is subject to adjustments for expenditures and eventualities prior to the
date of closing on the sale, is approximately $31 million, exclusive of nuclear
fuel. UI's share of the proceeds from the sale of the nuclear fuel inventory at
the date of closing on the sale is estimated to be approximately $2.5 million.
The sale is scheduled to be consummated on or about April 1, 2001 or as soon
thereafter as all requisite regulatory approvals are received. On December 15,
2000, UI and The Connecticut Light and Power Company filed with the DPUC for its
approval their plan to divest their respective interests in Seabrook Unit 1 by
an auction process. The DPUC has commenced hearings on this divestiture plan.

of American Payment Systems, Inc. of $29.9 million.

(2) Funds from Operations less Dividends, Capital Expenditures and External
Financing Requirements are estimates based on current earnings and cash
flow projections. The estimate of Cash from Plant Sales for 2001 is based
on current projections for the Millstone Unit 3 sale anticipated on or
about April 1, 2001. The estimate for Cash from Plant Sales for 2002 is
based on speculative pricing and other projections for the sale of Seabrook
Unit 1, including a sale date in early 2002. All of these estimates are
subject to change due to future events and conditions that may be
substantially different from those used in developing the projections.

All capital requirements that exceed available cash will have to be provided by
external financing. Although there is no commitment to provide such financing
from any source of funds, other than a $97.5 million revolving credit agreement
with a group of banks, future external financing needs are expected to be
satisfied by the issuance of additional short-term and long-term debt. The
continued availability of these methods of financing will be dependent on many
factors, including conditions in the securities markets, economic conditions,
and future income and cash flow.

See Item 8, "Notes to Consolidated Financial Statements," Note (E) for a
discussion of UIL Holdings' short-term credit arrangements.

On September 25, 2000, UI redeemed $50 million of 9 5/8% Preferred Capital
Securities, Series A, due 2025, at $25.00 per share, plus accrued dividends to
the redemption date of $0.160417 per share. These securities were


- 20 -


issued in April 1995 by United Capital Funding Partnership L. P., a Delaware
limited partnership that was dissolved following the redemption of the
securities.

On February 15, 2001, UIL Holdings issued and sold $75,000,000 of Senior Notes
to several institutional investors in a private sale. The issue was composed of
two series: 7.23% Senior Notes, Series A, due February 15, 2011, in the
principal amount of $30,000,000, and 7.38% Senior Notes, Series B, due February
15, 2011, in the principal amount of $45,000,000. Under the Senior Notes, Series
A, UIL Holdings is required to prepay the principal amount of $4,285,714 each
February 15th, beginning on February 15, 2005 and ending on February 15, 2010.
Interest due under the Senior Notes is payable semi-annually on February 15th
and August 15th. The net proceeds of the sale were used to repay short-term debt
of UIL Holdings.

At December 31, 2000, UIL Holdings had $47.4 million of cash and temporary cash
investments, a decrease of $20.9 million from the corresponding balance at
December 31, 1999. The components of this decrease, which are detailed in the

GENERAL IMPACTS OF CONNECTICUT'S RESTRUCTURING ACT ON UI FINANCIAL REPORTS
On April 16, 1999, UI completed the sale of its operating fossil-fueled
generating plants that was required by Connecticut's 1998 electric utility
industry restructuring legislation (Restructuring Act). On October 1, 1999, the
Connecticut Department of Public Utility Control (DPUC) issued its decision
establishing UI's standard offer customer rates, commencing January 1, 2000, at
a level 10% below 1996 rates (about 6% below 1999 rates), as directed by the
Restructuring Act. As a result of these two and other associated events, the
"geography" of UI's costs have changed. This particularly relates to regulated
retail pricing patterns, wholesale revenue and expense, other operating
revenues, retail purchased energy and fossil fuel expenses, operation and
maintenance expense, depreciation and property taxes. For example, increased
purchased energy expenses in 2000 are more than offset by portions of the
decreases in miscellaneous operation and maintenance expense, depreciation and
property taxes due to the sale of generating plants.

Wholesale sales margin increased by $48.3 million in 2000 compared to 1999. UI's
operating nuclear assets, Seabrook Unit 1 and Millstone Unit 3, supplied power
solely to the wholesale market in 2000. Wholesale margin from the Nuclear
Division, which was incorporated in retail rates in 1999, was $48.3 million in
2000 and accounted for all of the variance. Overall, the Nuclear Division
contributed earnings of $0.45 per share in 2000. This reflects the wholesale
sales margin, offset in part by additional maintenance costs resulting from a
Seabrook Unit 1 outage extension. The outage extension cost UI about $0.33 per
share in 2000.

Other operating revenues increased by $3.3 million in 2000 compared to 1999.
Other operating revenues include transmission revenues from the New England
Power Pool (NEPOOL), which increased by $4.3 million in 2000 compared to 1999
and were offset by an increase in transmission operation expense. Other revenue
items decreased by $1.0 million.

Retail fuel and energy expense increased by $124.7 million in 2000 compared to
1999. UI's operating fossil-fueled generation units were sold on April 16, 1999,
and UI receives, and will receive through 2003, electricity to satisfy its
standard offer retail customer service requirements through fixed-price
purchased power agreements. These costs are recovered through the Generation
Service Charge (GSC) portion of UI's unbundled retail customer rates.

UI's operating expenses for operation, maintenance and purchased capacity
decreased by $47.2 million in 2000 compared to 1999. The principal components of
these expense changes included:

Note (A): These costs were incurred in the fourth quarter of 1999 to repair
a riparian bulkhead in New Haven and for remediation of environmental
conditions at another site.

Note (B): Nuclear Division operation and maintenance expenses are incurred
in the business of producing energy for the wholesale market and are
reflected in the Nuclear Division results. These expenses decreased by $4.9
million in 2000 compared to 1999, due primarily to the absence of 1999
Millstone Unit 3 refueling outage costs and reductions in base expenses at
both Seabrook Unit 1 and Millstone Unit 3 that more than offset the
incremental costs associated with the Seabrook Unit 1 2000 outage.

Note (C): UI's wholesale purchased power agreements were assumed by Enron
Power Marketing, Inc. (EPMI) as part of an agreement for EPMI to supply the
power needed by UI to meet its standard offer retail customer service
obligations until the end of the four-year standard offer period (the end
of 2003) and the power needed to serve UI's special contract retail
customers for the remaining contract terms. UI has created a regulatory
asset and noncurrent liability to reflect this agreement, and the
regulatory asset is being amortized as part of the Competitive Transition
Assessment (CTA). The amortization for 2000 of about $26.8 million is
included in the "Amortization of regulatory assets" line of the income
statement.

Note (D): Conservation and load management and renewable energy costs are
pass-through costs recovered in unbundled retail customer rates.

Other taxes for UI decreased by $4.3 million in 2000 compared to 1999, due in
part to the sale of fossil generating units in April 1999.

Depreciation expense for UI decreased by $28.8 million in 2000 compared to 1999.
About $24.5 million of this decrease was due to the reclassification of
depreciation on nuclear plant stranded assets and other assets from depreciation
expense to amortization of regulatory assets within the Competitive Transition
Assessment (CTA). The remaining $4.3 million decrease was due primarily to the
sale of fossil generating units in 1999.



- 24 -


On December 31, 1996, the DPUC issued an order that implemented a five-year Rate
Plan to reduce UI's regulated retail prices and accelerate the recovery of
certain "regulatory assets." According to the Rate Plan, under which UI is
currently operating, "accelerated" amortization of past regulated utility
investments is scheduled for every year that the Rate Plan is in effect,
contingent upon UI earning a 10.5% return on regulated utility common equity.
Beginning in 2000, these accelerated amortizations are charged to the operating
Distribution Division, although they reduce CTA rate base. Additionally, any
"sharing" amortization required as a result of the Distribution Division
exceeding an 11.5% return on the equity portion of its rate base impacts the
Distribution Division earnings but reduces CTA rate base. UI is allowed to earn
an 11.5% return, no more and no less, on the equity portion of the CTA rate base
that includes all stranded assets. If CTA revenues and various costs included in
the CTA do not produce an 11.5% return, then plant amortizations are either
accelerated or deferred accordingly. A similar mechanism is in place to deal
with Systems Benefits Charges (SBC), but the impact is immaterial. The table
below shows the increases and decreases in 2000 compared to 1999 in major
amortizations of regulatory assets. The amortizations for the operating
Distribution Division impact earnings directly, and the amortizations for the
CTA and SBC impact earnings indirectly through changes to rate base.

$0.16 per share, in 1999. Operation expenses for the URI businesses, including
cost of goods sold, selling and administrative expenses, increased by $94.2
million in 2000 compared to 1999, almost entirely as the result of incorporating
acquired companies. Other taxes for URI increased by $0.7 million, reflecting
the expansion of these businesses. Depreciation and amortization expense for the
URI businesses increased by $1.0 million.

Interest charges for URI increased by a net $6.8 million in 2000, compared to
1999. The results of each of the subsidiaries of URI for 2000, as presented
below, reflect the allocation of debt costs from the parent based on a capital
structure, including an equity component and an interest rate deemed to be
appropriate for that type of business.

Earnings for APS increased $0.04 per share, or 36%, in 2000 compared to 1999,
due primarily to increased transaction volumes. Also, much of APS's field
equipment was fully depreciated, resulting in depreciation savings.

XCELECOM, INC.
Earnings for Xcelecom, Inc. increased by $0.36 per share in 2000 compared to
1999, due to the acquisitions completed in 2000 and continuing cost control
measures. Operating revenue increased by $103 million to $138 million in 2000.

URI PASSIVE INVESTMENTS

UNITED BRIDGEPORT ENERGY, INC. (UBE)
UBE lost $0.19 per share in 2000, compared to a loss of $0.01 per share in 1999.
The increased loss was due to a combination of factors that had adverse impacts
on the Bridgeport Energy generating plant: third quarter mild weather that
depressed energy sales prices; high gas prices that further reduced margins;
mechanical difficulties in the early part of the year that caused an extended
shutdown; and a one-time third quarter termination cost of a contractual
liability that is expected to benefit UBE's earnings in subsequent years. Fourth
quarter 2000 results reflect the recovery of $1.6 million of Installed Capacity
(ICAP) revenues, contributing $0.07 per share, based on a power purchaser's
agreement to pay in accordance with its power contract terms as a result of a
Federal Energy Regulatory Commission (FERC) ruling affirming the value of the
ICAP market in New England. However, these ICAP revenues are the subject of an
appeal to the FERC by other entities; and the FERC has temporarily stayed its
order pending a hearing. See the "Looking Forward" section for more information
on the ICAP proceeding and on plans to reduce the risk of the UBE investment.

UNITED CAPITAL INVESTMENTS, INC. (UCI)
UCI earned $0.11 per share in 2000, compared to a $0.03 per share loss in 1999,
due to gains on its passive investments.

URI HEADQUARTERS

URI, the holding company for all non-regulated businesses, lost $0.21 per share
in 2000 compared to a loss of $0.02 per share in 1999. The results of each of
the subsidiaries of URI, as presented above, reflect interest expense on
allocated debt from URI, based on a capital structure, including an equity
component, and an interest rate deemed to be appropriate for that type of
business. Some financial leveraging, and strategic and administrative costs for
the subsidiaries of URI, are retained by the parent URI.

Net wholesale margin (wholesale revenue less wholesale expense) decreased by
$10.4 million in 1999 compared to 1998, due to lower wholesale sales. Other
operating revenues, which include NEPOOL related transmission revenues,
increased by $6.4 million. NEPOOL transmission revenues are recoveries, for the
most part, of NEPOOL transmission expense and reflect new accounting
requirements implemented by the Federal Energy Regulatory Commission.

Operating expenses for operations, maintenance and purchased capacity charges
decreased by $5.7 million in 1999 compared to 1998. The principal components of

On December 31, 1996, the Connecticut Department of Public Utility Control
issued an order that implemented a five-year Rate Plan to reduce UI's retail
prices and accelerate the recovery of certain "regulatory assets." According to
the Rate Plan, under which UI is currently operating, "accelerated" amortization
of past utility investments is scheduled for every year that the Rate Plan is in
effect, contingent upon UI earning a 10.5% return on utility common stock
equity. All of the scheduled accelerated amortization for 1998, amounting to
$13.1 million before-tax ($8.5 million after-tax), was recorded against earnings
from operations in 1998. UI recorded all of the scheduled accelerated
amortization for 1999 by amortizing regulatory income tax assets, totaling $12.1
million after-tax ($20 million pre-tax equivalent).

UI can also incur additional accelerated amortization expense as a result of the
"sharing" mechanism in the Rate Plan, if UI achieves a return on utility common
stock equity above 11.5%, which UI did achieve during the third quarter of 1999.
One-time items recorded against the return on utility common stock equity,
before UI achieves the 11.5%, are recorded with an appropriate "sharing" effect
if UI projects, at that time, that there will be total "sharing" for the year
adequate to cover the "sharing" for the one-time item. Such "sharing"
amortization was recorded in the first quarter of 1999, in the amount of $1.0
million before-tax ($0.6 million after-tax), as a result of the one-time gain
recorded in that quarter. "Sharing" amortization from operations of $10.0
million after-tax ($16.7 million before-tax) was recorded in 1999. "Sharing"
amortizations recorded and imputed in the first nine months of 1998 were: $0.5
million before-tax ($0.3 million after-tax) as a result of a one-time item, and
$2.1 million before-tax ($1.2 million after-tax) from operations. "Sharing"
amortization recorded against earnings from operations in the fourth quarter of
1998 was imputed to be $0.6 million before-tax ($0.3 million after-tax). All of
those 1998 "sharing" amortizations were reversed in the fourth quarter of 1998
as a result of the impact of a one-time charge recorded in that quarter.

Interest charges continued on a downward trend, decreasing by $12.8 million for
the regulated business in 1999 compared to 1998, partly offset by an increase of
$3.5 million in interest charges for non-regulated subsidiaries. Most of the
reduction in utility interest charges occurred after the generation asset sale,
which was completed on April 16, 1999. On that date, UI used proceeds received
from the sale of plant to pay off $205 million of debt.

construction of the second phase, and additional unscheduled outages and higher
gas prices in the fourth quarter of 1999. Other non-regulated subsidiary
operations lost approximately $1.2 million in 1999, compared to a similar loss
in 1998.

A LOOK AT 2001
- --------------

UIL Holdings expects that its 2001 earnings will be $4.40-$4.50 per share. This
range reflects compound annual growth of about 11% from earnings from operations
of $2.93 per share in 1997. The primary reasons for the projected increase in
the earnings are: management's commitment to reducing costs while sales increase
at its regulated electric utility subsidiary, and its confidence in the ability
of its non-regulated subsidiary businesses to execute the strategic growth plans
of the various businesses. Further details are explained below.

The United Illuminating Company (UI)
- -----------------------------------

Five-year Rate Plan

On December 31, 1996, the Connecticut Department of Public Utility Control
(DPUC) issued an order (the Order) that implemented a five-year regulatory
framework (Rate Plan) to reduce UI's regulated retail prices and accelerate the
recovery of certain "regulatory assets," beginning with deferred conservation
costs. UI has operated under the terms of this Order since January 1, 1997. The
Order's schedule of price reductions and accelerated amortizations was based on
a DPUC pro-forma financial analysis that anticipated UI would be able to
implement such changes and earn an allowed annual return on common equity
invested in regulated utility assets of 11.5% over the period 1997 through 2001.
The Order established a set formula to share any regulated utility income that
would produce a return above the 11.5% level: one-third to be applied to
customer price reductions, one-third to be applied to


- 30 -


additional amortization of regulatory assets, and one-third to be retained by
shareowners (see "Sharing Implementation" below). Regulated utility income for
this purpose is inclusive of earnings from operations and one-time items.

Sharing Implementation

"Sharing" in 2001 will result only if UI's regulated operating Distribution
Division exceeds its allowed return of 11.5% on its portion of regulated utility
common equity. Earnings subject to sharing does not include the Competitive
Transition Assessment (CTA) and other unbundled utility components. UI is
allowed to earn an 11.5% return, no more and no less, on the equity portion of
the CTA rate base that includes all stranded assets. The CTA return, therefore,
is not subject to "sharing." Distribution Division earnings will not likely
exceed the sharing level before the third quarter of 2001. Assuming the sharing
level of earnings is exceeded in the third quarter of 2001, then earnings in the
third quarter that exceed that level and all positive regulated Distribution
Division earnings recorded in the fourth quarter of 2001 will be subject to
"sharing."

The framework of the current Rate Plan, including the "sharing" mechanism, is
expected to continue at least through 2001. Regulatory decisions during 1999 did
not alter UI's allowed return of 11.5% on regulated utility equity, and did not
impinge on UI's ability to achieve that return.

UI EARNINGS ESTIMATES FOR 2001

If UI were to earn 11.5% on regulated utility equity, excluding the Nuclear
Division, that level of earnings would generate $3.25-$3.35 per share for UIL
Holdings.

UI is allowed to earn an 11.5% return on the equity portions of CTA and the SBC
rate base (the latter is minimal), no more and no less. For the most part, the
regulatory assets that are being recovered through the CTA are being amortized
on a straight-line basis. If CTA revenues and expenses produce a return more or
less than the allowed return, then deferred accounting or accelerated
amortization is used to "true-up" to the allowed return. This true-up adjusts
for sales volume fluctuations as well as pricing factors. A similar adjustment,
on a much less significant scale, applies to the SBC component.

The generation service, conservation and renewables charges are pass-through
charges, based on rates that were set for the standard offer period through
2003. In the case of generation service, UI has contracted with Enron Power
Marketing, Inc., a subsidiary of Enron Corp., for all of UI's retail customer
standard offer service requirements, through 2003, on a fixed-price basis. This
agreement protects UIL Holdings' shareowners and UI's retail customers from the
type of market and pricing volatility that is being experienced in California,
regardless of demand and volume requirements. The only retail electricity sales
volume fluctuations that impact UI's net income are those that apply to the
operating Distribution Division component of rates. Thus, a 1% sales volume
increase will produce additional sales margin of about $2.4 million in 2001. The
Distribution Division was impacted negatively in 2000 by a 0.9% sales decrease,
due to mild summer weather.

A mandated increase in Distribution Division accelerated amortization expense,
the absence of a significant one-time gain that occurred in 2000, and other 2001
cost increases relative to 2000 would, absent management action, likely prevent
Distribution Division earnings from exceeding the 11.5% allowed return level in
2001. However, UI has a major process reengineering effort underway, and expects
that effort to produce enough savings in 2001 for it to retain as much as an
additional $0.05 per share after sharing.

The Nuclear Division contributed $0.45 per share to UIL Holdings' results for
2000. The scheduled four-week refueling outage for the Seabrook nuclear
generating unit that began on October 21, 2000 was extended, adding six weeks of
unscheduled outage in 2000 and an additional four and one-half weeks in 2001.
The total negative impact of the refueling outage and the six-week outage
extension on the 2000 earnings contribution of the Nuclear Division to UIL
Holdings was approximately $0.33 per share. The remaining four and one-half
weeks of outage in 2001 should have an impact on 2001 earnings similar to the
impact the regularly scheduled 2000 four-week outage had on 2000 earnings.
Assuming Seabrook operates normally for the remainder of 2001, the contribution
to earnings in


- 31 -


2001 of the Seabrook unit should be about the same as the 2000 earnings. It is
possible for earnings to improve slightly from that level if the unit operates
at near full capacity as it did in 2000 before the refueling outage began.

UIL Holdings currently expects to complete the sale of its Millstone Unit 3
nuclear generating unit entitlement on or about April 1, 2001. The impact of the
sale and a refueling outage scheduled for the first quarter on the earnings of
the Nuclear Division in the first quarter of 2001 is expected to be negligible.
That unit's impact on 2000 earnings for the Nuclear Division was also
immaterial. An estimated impact of the Millstone sale on the CTA is incorporated
in UI's earnings projections for 2001.

Overall, UI, including the Nuclear Division, is expected to contribute
$3.75-$3.85 to UIL Holdings' earnings per share in 2001.

URI EARNINGS ESTIMATES

UIL Holdings' non-regulated businesses, under the parent URI, are expected to
earn $0.60-$0.70 per share in 2001.

APS is expected to contribute only about $0.00-$0.05 per share to UIL Holdings
in 2001, although its base business is expected to contribute about 15% more
than the $0.15 per share earned in 2000. The expected reduction in earnings from
the base business reflects anticipated strategic expenses designed to produce
future earnings enhancements in the non-contracted payment segment of its
business. Management's experience with Xcelecom indicates that incurring
short-term strategic expenses to build an appropriate management team and
processes that are necessary to grow through acquisitions and product and
service enhancements will increase shareowner value in the longer term.
Management believes that experience will be equally applicable to APS.

Earnings for Xcelecom increased from a loss of $0.21 per share in 1999 to
positive earnings of $0.15 per share in 2000. The acquisitions completed in 2000
and continuing cost control measures are the reasons for the increase. This
strategy is expected to produce further earnings increases in 2001, based on a
full year's impact of the 2000 acquisitions, and earnings could further improve
through additional acquisitions in 2001. Based on past performance and the
assumed accomplishment of a portion of its 2001 acquisition plan, Xcelecom is
expected to contribute $0.55-$0.60 per share in 2001.

Earnings from URI's passive investments offset by headquarters' costs are
expected to contribute $0.00-$0.05 per share in 2001. These investments include
United Bridgeport Energy, Inc. (UBE), which is expected to contribute about
$0.20 per share in 2001. UBE's expected contribution assumes the favorable
outcome of an important pending matter that management is confident will come
about, although there can be no assurance that it will occur. The assumption is
the anticipated recording of UBE's portion of ICAP revenues in 2001, producing
about $0.25 per share for UBE. The Federal Energy Regulatory Commission (FERC),
in a ruling in 2000, affirmed the value of the ICAP market in New England,
thereby validating a pre-existing contract of Bridgeport Energy for ICAP
revenues. However, the FERC ICAP order is the subject of appeal to the FERC by
some other entities, and, as a result, the FERC has temporarily stayed its order
pending a hearing. DETM may be able to book some ICAP revenues, in spite of the
stay, if, as anticipated, the customer continues to pay for its contracted ICAP.

As stated previously, as a result of management's continued confidence in the
potential of the non-regulated businesses, UIL Holdings is evaluating further
investments in this area. Near-term losses could be incurred due to these new
growth initiatives, if the potential for future earnings is deemed to warrant
such losses.

Quarterly Earnings Pattern for 2001
- -----------------------------------

The 2001 quarterly earnings pattern for UI is expected to be different than the
2000 pattern. Nuclear Division outages in the first quarter of 2001 will reduce
earnings compared to the first quarter of 2000. Higher mandated amortization
expense for the Distribution Division will be spread evenly throughout the year,
which will further reduce earnings relative to 2000 in the first two quarters of
2001. Since UI is not projecting any significant "sharing" in 2001 at this time,
the third and fourth quarters of 2001 should show an improvement compared to the
corresponding quarters in 2000. UIL Holdings makes every effort to incorporate
such impacts, including the sharing impact, in its earnings estimates as each
quarter is reported.



- 32 -


Actual 2001 results may vary depending on changes due to weather, economic
conditions, sales mix (the usage pattern of the Distribution Division's retail
customers), the ability to control expenses, and other unanticipated events.
These factors can change from quarter to quarter.

UIL Holdings' current overall estimate of earnings per share from operations for
2001 is $4.40-$4.50 and the estimates of quarterly results are as follows:

Earnings per share from operations:
Estimated Actual
Quarter 2001 Range* 2000
------- ----------- ----
1 $0.65 - $0.70 $1.20
2 $1.00 - $1.05 1.41
3 $1.65 - $1.70 1.19
4 $1.05 - $1.10 0.46
-----
$4.26

*Quarterly range estimates are not additive, that is, adding the low range
numbers produces a result that is lower than UIL Holdings' low estimate for the
year, and adding the high range numbers produces a result that is higher than
UIL Holdings' high estimate for the year. The sums of the low and high range
values should not be construed to represent any estimate other than UIL
Holdings' annual estimate of $4.40-$4.50 per share. The quarterly range
estimates do not add to the total UIL Holdings' range for the year because
impacts in one quarter can affect the results of other quarters through the
sharing mechanism and through timing of activities.

UIL HOLDINGS CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

UIL Holdings Corporation (UIL Holdings) is the parent holding company for The
United Illuminating Company (UI) and United Resources, Inc (URI) and is not
itself an operating company. This holding company structure became effective on
July 20, 2000 as a result of the corporate restructuring of UI and its direct
and indirect non-regulated subsidiaries. All of UI's interests in all of its
direct and indirect non-regulated subsidiaries have been transferred to UIL
Holdings and, to the extent new businesses are subsequently acquired or
commenced, UIL Holdings expects they will be financed and owned by UIL Holdings.
UIL Holdings is an exempt public utility holding company under the provisions of
the Public Utility Holding Company Act of 1935.

UI is a regulated operating electric public utility established in 1899. It is
engaged principally in the purchase, transmission, distribution and sale of
electricity for residential, commercial and industrial purposes in a service
area of about 335 square miles in the southwestern part of the State of
Connecticut. The population of this area is approximately 704,000, which
represents approximately 21% of the population of the State. The service area,
largely urban and suburban in character, includes the principal cities of
Bridgeport (population approximately 137,000) and New Haven (population
approximately 124,000) and their surrounding areas. Situated in the service area
are retail trade and service centers, as well as large and small industries
producing a wide variety of products, including helicopters and other
transportation equipment, electrical equipment, chemicals and pharmaceuticals.
Of UI's 2000 retail electric revenues, approximately 42% were derived from
residential sales, 40% from commercial sales, 16% from industrial sales and 2%
from other sales.

URI serves as the parent company for UIL Holdings' four non-regulated
businesses, each of which is wholly owned. American Payment Systems, Inc. (APS)
manages a national network of agents for the processing of bill payments made by
customers of UI and other companies. APS is one of the largest vendors in the
nation for walk-in payment of utility bills and already services approximately
25% of the market. Xcelecom, Inc. (formerly known as Precision Power, Inc.) and
its subsidiaries provide specialty electrical and voice-data-video integrated
solutions in regional markets of the Northeastern United States. A third
subsidiary, United Capital Investments, Inc., and its subsidiaries invest in
business ventures that are expected to earn above-average returns. URI's fourth
subsidiary, United Bridgeport Energy, Inc., owns, as a passive investor, 331/3 %
of a merchant wholesale electric generating facility that is co-owned and
operated by a unit of Duke Energy and is located in Bridgeport, Connecticut.

The consolidated financial statements of UIL Holdings and its wholly-owned
direct subsidiaries, UI and URI, have been prepared pursuant to the rules and
regulations of the Securities and Exchange Commission (SEC). UIL Holdings'
Consolidated Financial Statements include the accounts of UIL Holdings and its
wholly-owned subsidiaries, UI and URI. UIL Holdings' prior period consolidated
financial statements have been prepared from UI's prior period consolidated
financial statements, except that amounts have been reclassified to reflect UIL
Holdings' structure.

(A) STATEMENT OF ACCOUNTING POLICIES

ACCOUNTING RECORDS

The accounting records for UI are maintained in accordance with the uniform
systems of accounts prescribed by the Federal Energy Regulatory Commission
(FERC) and the Connecticut Department of Public Utility Control (DPUC).

The accounting records of UIL Holdings' non-regulated subsidiaries are
maintained in conformity with generally accepted accounting principles.



- 39 -


UIL HOLDINGS CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)

PRESENTATION

The consolidated financial statements include the accounts of UIL Holdings and
its wholly-owned subsidiaries, UI and URI. Intercompany accounts and
transactions have been eliminated in consolidation.

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

Certain amounts previously reported have been reclassified to conform with
current year presentation.

REGULATORY ACCOUNTING

Generally accepted accounting principles for regulated entities in the United
States of America allow UI to give accounting recognition to the actions of
regulatory authorities in accordance with the provisions of Statement of
Financial Accounting Standards (SFAS) No. 71, "Accounting for the Effects of
Certain Types of Regulation." In accordance with SFAS No. 71, UI has deferred
recognition of costs (a regulatory asset) or has recognized obligations (a
regulatory liability) if it is probable that such costs will be recovered or
obligations relieved in the future through the ratemaking process. In addition
to the Regulatory Assets and Liabilities separately identified on the
Consolidated Balance Sheet, there are other regulatory assets and liabilities
such as conservation and load management costs and certain deferred tax
liabilities. UI also has obligations under long-term power contracts, the
recovery of which is subject to regulation. If UI, or a portion of its assets or
operations, were to cease meeting the criteria for application of these
accounting rules, accounting standards for businesses in general would become
applicable and immediate recognition of any previously deferred costs, or a
portion of deferred costs, would be required in the year in which the criteria
are no longer met, if such deferred costs are not recoverable in the portion of
the business that continues to meet the criteria for application of SFAS No. 71.

The Restructuring Act enacted in Connecticut in 1998 provides for UI to recover
previously deferred costs through ongoing assessments to be included in future
regulated service rates. See Note (C), "Rate-Related Regulatory Proceedings" for
a discussion of the nature, amount and timing of recovery of UI's stranded costs
associated with the generation portion of its assets and operations, as well as
a discussion of the regulatory decisions that provide for such recovery. Based
on these regulatory decisions, the sale of UI's fossil-generation assets and the
planned divestiture of its nuclear generation ownership interests by the end of
2003, on December 31, 1999 UI discontinued applying SFAS No. 71 to the
generation portion of its assets and operations. However, based on the recovery
mechanism that allows recovery of all of its stranded costs through its standard
offer rates, UI was not required to take any write-offs in connection with this
event. UI expects to continue to meet the criteria for application of SFAS No.
71 for the remaining portion of its assets and operations for the foreseeable
future. If a change in accounting were to occur to the non-generation portion of
UI's operations, it could have a material adverse effect on UI's earnings and
retained earnings in that year and could have a material adverse effect on UI's
ongoing financial condition as well.

PROPERTY, PLANT AND EQUIPMENT

The cost of additions to property, plant and equipment and the cost of renewals
and betterments are capitalized. Cost consists of labor, materials, services and
certain indirect construction costs, including an allowance for funds used
during construction (AFUDC) in the case of utility plant. The cost of current
repairs and minor replacements is charged to appropriate operating expense
accounts. The original cost of property, plant and equipment retired or
otherwise disposed of and the cost of removal, less salvage, are charged to the
accumulated provision for depreciation.

UIL HOLDINGS CORPORATION

-------------- ---------------
$962,485 $1,031,601
============== ===============

See Note (C), "Rate-related Regulatory Proceedings" for a discussion of the sale
by UI of its two operating fossil-fueled generating stations and the regulatory
decisions allowing for recovery of stranded costs, including the above-market
investment in nuclear generating units.

DEPRECIATION

Provisions for depreciation on utility plant for book purposes are computed on a
straight-line basis, using estimated service lives determined by independent
engineers. One-half year's depreciation is taken in the year of addition and
disposition of utility plant, except in the case of major operating units on
which depreciation commences in the month they are placed in service and ceases
in the month they are removed from service. The aggregate annual provisions for
depreciation for the years 2000, 1999 and 1998 were approximately 3.05%, 3.29%
and 3.45%, respectively, of the original cost of depreciable property.

INCOME TAXES

In accordance with Statement of Financial Accounting Standards (SFAS) No. 109,
"Accounting for Income Taxes," UIL Holdings has provided deferred taxes for all
temporary book-tax differences using the liability method. The liability method
requires that deferred tax balances be adjusted to reflect enacted future tax
rates that are anticipated to be in effect when the temporary differences
reverse. In accordance with generally accepted accounting principles for
regulated industries, UI has established a regulatory asset for the net revenue
requirements to be recovered from customers for the related future tax expense
associated with certain of these temporary differences.

For ratemaking purposes, UI normalizes all investment tax credits (ITC) related
to recoverable plant investments except for the ITC related to Seabrook Unit 1,
which was taken into income in accordance with provisions of a 1990 DPUC retail
rate decision.

REVENUES

Regulated utility revenues for UI are based on authorized rates applied to each
customer's use of electricity. These rates are approved by the DPUC and can be
changed only through formal proceedings. At the end of each accounting period,
the estimated amount of revenues (less related expenses and applicable taxes)
for services rendered but not billed is accrued.



- 41 -



UIL HOLDINGS CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)

Revenues from construction contracts entered into by Xcelecom, Inc., a
wholly-owned subsidiary of URI, are recognized on a percentage-of-completion
method. Under this method, revenue is recognized based on the percentage of
costs incurred and accrued to date to the estimated total cost to complete these
contracts.

CASH AND TEMPORARY CASH INVESTMENTS

For cash flow purposes, UIL Holdings considers all highly liquid debt
instruments with a maturity of three months or less at the date of purchase to
be cash and temporary cash investments.

UI is required to maintain an operating deposit with the project disbursing
agent related to its 17.5% ownership interest in Seabrook Unit 1. This operating
deposit, which is the equivalent to one and one half months of the funding
requirement for operating expenses, is restricted for use and amounted to $3.3
million and $2.3 million at December 31, 2000 and 1999, respectively.

URI's wholly-owned subsidiary, American Payment Systems, Inc., maintains
separate bank accounts for holding cash received from clients' customers before
the amounts are transferred to clients. The amount of this restricted cash at
December 31, 2000 and 1999 was $29.9 million and $26.9 million, respectively.

INVESTMENTS

UI's investment in the Connecticut Yankee Atomic Power Company, a nuclear
generating company in which UI has a 9.50% stock interest, is accounted for on
an equity basis. This investment amounted to $7.1 million and $10.0 million at
December 31, 2000 and 1999, respectively, and is included on the Consolidated
Balance Sheet as a regulatory asset. See Note (L), "Commitments and
Contingencies - Other Commitments and Contingencies - Connecticut Yankee."

GOODWILL

Goodwill represents the excess of the aggregate of purchase price paid in the
acquisition of businesses accounted for as purchases over the estimated fair
market value of the net assets acquired. Goodwill is amortized on a
straight-line basis over 15 or 20 years.

UIL Holdings periodically evaluates the recoverability of intangibles resulting
from business acquisitions and measures the amount of impairment, if any, by
assessing current and future levels of income and cash flows as well as other
factors, such as business trends and prospects and market and economic
conditions. If an impairment evaluation is required, the estimated future
undiscounted cash flows associated with the asset will be compared to the
asset's carrying amount to determine if such an impairment exists.

RESEARCH AND DEVELOPMENT COSTS

Research and development costs, including environmental studies, are charged to
expense as incurred.

PENSION AND OTHER POSTEMPLOYMENT BENEFITS

UIL Holdings accounts for normal pension plan costs in accordance with the
provisions of Statement of Financial Accounting Standards (SFAS) No. 87,
"Employers' Accounting for Pensions."

UIL Holdings accounts for other postemployment benefits, consisting principally
of health and life insurance, under the provisions of SFAS No. 106, "Employers'
Accounting for Postretirement Benefits Other Than Pensions," which requires,
among other things, that the liability for such benefits be accrued over the
employment period that

encompasses eligibility to receive such benefits. The annual incremental cost of
this accrual has been allowed in retail rates in accordance with a 1992 rate
decision of the DPUC.

URANIUM ENRICHMENT OBLIGATION

Under the Energy Policy Act of 1992 (Energy Act), UI will be assessed for its
proportionate share of the costs of the decontamination and decommissioning of
uranium enrichment facilities operated by the Department of Energy. The Energy
Act imposes an overall cap of $2.25 billion on the obligation assessed to the
nuclear utility industry and limits the annual assessment to $150 million each
year over a 15-year period. UI has recovered these assessments in rates as a
component of fuel expense. Accordingly, UIL Holdings has recognized the
unrecovered costs as a regulatory asset on its Consolidated Balance Sheet. At
December 31, 2000, UI's remaining share of the obligation, based on its
ownership and leasehold interests in Seabrook Unit 1 and Millstone Unit 3, was
approximately $1.0 million.

NUCLEAR DECOMMISSIONING TRUSTS

External trust funds are maintained to fund the estimated future decommissioning
costs of the nuclear generating units in which UI has an ownership interest.
These costs are accrued as a charge to depreciation expense over the estimated
service lives of the units and are recovered in rates on a current basis. UI
paid $4.0 million, $4.0 million and $2.6 million during 2000, 1999 and 1998 into
the decommissioning trust funds for Seabrook Unit 1 and Millstone Unit 3. At
December 31, 2000, UI's shares of the trust fund balances, which included
accumulated earnings on the funds, were $24.2 million and $8.6 million for
Seabrook Unit 1 and Millstone Unit 3, respectively. These fund balances are
included in "Other Property and Investments" and the accrued decommissioning
obligation is included in "Noncurrent Liabilities" on the Consolidated Balance
Sheet.

IMPAIRMENT OF LONG-LIVED ASSETS

Statement of Financial Accounting Standards (SFAS) No. 121, "Accounting for the
Impairment of Long-Lived Assets to Be Disposed Of" requires the recognition of
impairment losses on long-lived assets when the book value of an asset exceeds
the sum of the expected future undiscounted cash flows that result from the use
of the asset and its eventual disposition. This standard also requires that
rate-regulated companies recognize an impairment loss when a regulator excludes
all or part of a cost from rates, even if the regulator allows the company to
earn a return on the remaining allowable costs. Under this standard, the
probability of recovery and the recognition of regulatory assets under the
criteria of SFAS No. 71 must be assessed on an ongoing basis. At December 31,
2000 and 1999, UI did not have any assets that are impaired under this standard.

STOCK-BASED COMPENSATION

UIL Holdings accounts for employee stock-based compensation in accordance with
Statement of Financial Accounting Standards (SFAS) No. 123, "Accounting for
Stock-Based Compensation." This statement establishes financial accounting and
reporting standards for stock-based employee compensation plans, such as stock
purchase plans, stock options, restricted stock, and stock appreciation rights.
The statement defines the methods of determining the fair value of stock-based
compensation and requires the recognition of compensation expense for book
purposes. However, the statement allows entities to continue to measure
compensation expense in accordance with the prior authoritative literature, APB
No. 25, "Accounting for Stock Issued to Employees," but requires that pro forma
net income and earnings per share be disclosed for each year for which an income
statement is presented as if SFAS No. 123 had been applied. The accounting
requirements of this statement are effective for transactions entered into after
1995. However, pro forma disclosures must include the effects of all awards
granted after January 1, 1995.

COMPREHENSIVE INCOME

Comprehensive income for the years ended December 31, 2000, 1999 and 1998 was
equal to net income as reported.

NEW ACCOUNTING STANDARDS

The Financial Accounting Standards Board issued SFAS No. 133, "Accounting for
Derivative Instruments and Hedging Activities." This statement, which will
become effective for UIL Holdings in the first quarter of 2001, establishes
accounting and reporting standards for derivative instruments and for hedging
activities. It requires entities to recognize all derivatives as either assets
or liabilities in the statement of financial position and measure those



- 44 -

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)

instruments at fair value. The accounting for the changes in the fair value of a
derivative (gains and losses) would depend on the intended use and designation
of the derivative. UI has a contract with a power marketer that includes a
financially settled contract for differences related to certain call rights of
the power marketer and put rights of UI with respect to UI's entitlements in
Seabrook Unit 1 and Millstone Unit 3. This contract will terminate at the
earlier of December 31, 2003 or the date that UI sells its interest in these
units. Application of the new accounting standard will require the recognition
of UI's future obligation for financial settlements under this contract. As of
December 31, 2000, UI's estimated future obligation for financial settlements
under this contract is approximately $18 million. This future obligation has
been estimated using assumptions regarding the future market price for power,
the operations of the units, and the projected future sale dates for UI's
interest in these units. If actual market prices, the operations of the units,
and the actual dates of sale differ significantly from these assumptions, the
actual amount paid for financial settlement of this contract will vary
significantly from this estimate. However, since the costs of this contract are
considered in the annual reconciliation of the Competitive Transition
Assessment, there is currently no income statement effect. The adoption of this
accounting statement will not have any impact on UIL Holdings' results of
operations and is not expected to have a material impact on UIL Holdings'
financial condition.

(B) CAPITALIZATION

COMMON STOCK

UIL Holdings had 14,321,177 shares of its common stock, no par value,
outstanding at December 31, 2000 and 14,334,922 shares of its common stock, no
par value, outstanding at December 31, 1999, of which 244,480 shares and 272,420
shares were unallocated shares held by UI's 401(k)/Employee Stock Ownership Plan
(KSOP) and not recognized as outstanding for accounting purposes as of December
31, 2000 and 1999, respectively.

UI has entered into an arrangement under which it loaned $11.5 million to the
KSOP. The trustee for the KSOP used the funds to purchase shares of UI common
stock in open market transactions. On July 20, 2000, effective with the
formation of the holding company structure, unallocated shares held by the KSOP
were converted into shares of UIL Holdings' common stock. The shares will be
allocated to employees' KSOP accounts, as the loan is repaid, to cover a portion
of the required KSOP contributions. The loan will be repaid by the KSOP over a
twelve-year period, using employer contributions and UIL Holdings' dividends
paid on the unallocated shares of the stock held by the KSOP. As of December 31,
2000, 244,480 shares, with a fair market value of $12.2 million, had been
purchased by the KSOP and had not been committed to be released or allocated to
KSOP participants.

In 1990, UI's Board of Directors and the shareowners approved a stock option
plan for officers and key employees of UI. Effective with the formation of the
holding company structure on July 20, 2000, all outstanding options were
converted into options to purchase an equivalent number of shares of UIL
Holdings' common stock. Options to purchase 3,500 shares of stock at an exercise
price of $30 per share, 7,800 shares of stock at an exercise price of $39.5625
per share, and 5,000 shares of stock at an exercise price of $42.375 per share
have been granted and remained outstanding at December 31, 2000. None of these
options were exercised during 2000.

On March 22, 1999, UI's Board of Directors approved a stock option plan for
directors, officers and key employees of UI. The plan provides for the awarding
of options to purchase up to 650,000 shares of UI's common stock over periods of
from one to ten years following the dates when the options are granted. The
exercise price of each option cannot be less than the market value of the stock
on the date of the grant. On June 28, 1999, UI's shareowners approved the plan.
Effective with the formation of the holding company structure on July 20, 2000,
all outstanding options were converted into options to purchase an equivalent
number of shares of UIL Holdings' common stock. Options to purchase 6,300 shares
of stock at an exercise price of $43.50 per share, 121,925 shares of stock at an
exercise price of $43.21875 per share, 183,800 shares of stock at an exercise
price of $39.40625 per share, 2,170 shares of stock at an exercise price of

On February 23, 1998, UI's Board of Directors granted 80,000 "phantom" stock
options to Nathaniel D. Woodson upon his appointment as President of UI.
Effective with the formation of the holding company structure on July 20, 2000,
all outstanding phantom stock options were converted to UIL Holdings' phantom
stock options. On each of the first five anniversaries of the grant date, 16,000
phantom stock options become exercisable and can be exercised at any time within
Mr. Woodson's period of employment with UI by means of UI paying him the
difference between the prevailing market price for each share of UIL Holdings'
common stock and the phantom stock option price of $45.16 per share. At ten
years after the grant date any unexercised phantom stock options will expire. At
December 31, 2000, 32,000 phantom stock options were exercisable. During 2000,
$282,000 was recognized as expense with regard to these phantom stock options.

RETAINED EARNINGS RESTRICTION

The indenture under which UI has issued $200 million principal amount of Notes
places limitations on UI relative to the payment of cash dividends on its common
stock, which is wholly-owned by UIL Holdings, and the purchase or redemption of
said common stock. Retained earnings in the amount of $117.9 million were free
from such limitations at December 31, 2000.

COMPANY-OBLIGATED MANDATORILY REDEEMABLE SECURITIES OF SUBSIDIARY HOLDING SOLELY
PARENT DEBENTURES

On September 25, 2000, UI redeemed $50 million of 9 5/8% Preferred Capital
Securities, Series A, due 2025, at $25.00 per share, plus accrued dividends to
the redemption date of $0.160417 per share. These securities were issued in
April 1995 by United Capital Funding Partnership L. P., a Delaware limited
partnership (United Capital).

United Capital was a special purpose limited partnership in which UI owned all
of the general partner interests. Its only asset was $50 million of 9 5/8%
Junior Subordinated Deferrable Interest Debentures, Series A, due April 30,
2025, issued by UI in 1995, which were repaid by UI in conjunction with United

(C) RATE-RELATED REGULATORY PROCEEDINGS

On December 31, 1996, the Connecticut Department of Public Utility Control
(DPUC) completed a financial and operational review of UI and ordered a
five-year incentive regulation plan for the years 1997 through 2001 (the Rate
Plan). The Rate Plan accelerates the amortization and recovery of unspecified
assets during 1999-2001 if UI's common equity return on regulated utility
investment exceeds 10.5% after recording the amortization. UI's authorized
return on regulated utility common equity during the period is 11.5%. Earnings
above 11.5%, on an annual basis, are utilized one-third for customer price
reductions, one-third to increase amortization of assets, and one-third retained
as earnings.

The Rate Plan included a provision that it could be reopened and modified upon
the enactment of electric utility restructuring legislation in Connecticut. On
October 1, 1999, the DPUC issued a decision establishing UI's standard offer
customer rates, commencing January 1, 2000, at a level 10% below 1996 rates, as
directed by the Restructuring Act described in detail below. These standard
offer customer rates supersede the rates that were included in the Rate Plan.
The decision also reduced the required amount of accelerated amortization in
2000 and 2001. Under this 1999 decision, all other components of the 1996 Rate
Plan are expected to remain in effect through 2001. The Connecticut Office of
Consumer Counsel (OCC), the statutory representative of consumer interests in
public utility matters, appealed the DPUC's standard offer decision to the
Connecticut Superior Court, challenging the DPUC's determination of UI's average
prices in 1996 rates from which a 10% reduction is required by the Restructuring
Act. On February 22, 2001, the Superior Court dismissed the OCC's appeal from
the DPUC's decision; but UI is unable to predict, at this time, whether the OCC
will appeal from the Superior Court's decision to the Connecticut Appellate
Court.

On February 13, 2001, the Connecticut Attorney General and the OCC petitioned
the DPUC to initiate a proceeding and hold a hearing concerning the need to
decrease UI's rates by reason of UI' s having earned a return on regulated
common equity more than 1% above the authorized level of 11.5% for at least six
consecutive months. UI believes that a hearing would confirm that UI has
complied with the DPUC-ordered earnings sharing mechanism in UI's rate plan; and
it will contest vigorously any arguments for a rate decrease.

In April 1998, Connecticut enacted Public Act 98-28 (the Restructuring Act), a
massive and complex statute designed to restructure the State's regulated
electric utility industry. As a result of the Restructuring Act, the business of
generating and selling electricity directly to consumers has been opened to
competition. These business activities are separated from the business of
delivering electricity to consumers, also known as the transmission and
distribution business. The business of delivering electricity remains with the
incumbent franchised utility companies (including UI) which continue to be
regulated by the DPUC as Distribution Companies. Since mid-1999, Distribution
Companies have been required to separate on consumers' bills the electricity
generation services component from the charge for delivering the electricity and
all other charges.

A major component of the Restructuring Act is the collection, by Distribution
Companies, of a "competitive transition assessment," a "systems benefits
charge," an "energy conservation and load management program charge" and a
"renewable energy investment charge." The competitive transition assessment
represents costs that have been reasonably incurred by, or will be incurred by,
Distribution Companies to meet their public service obligations as electric
companies, and that will likely not otherwise be recoverable in a competitive
generation and supply market.


- 49 -


UIL HOLDINGS CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)

These costs include above-market long-term purchased power contract obligations,
regulatory asset recovery and above-market investments in power plants
(so-called stranded costs). The systems benefits charge represents public policy
costs, such as generation decommissioning and displaced worker protection costs.
Beginning in 2000, a Distribution Company has been required to collect the
competitive transition assessment, the systems benefits charge, the energy
conservation and load management program charge and the renewable energy
investment charge from all Distribution Company customers.

Under the Restructuring Act, all of UI's customers are able to choose their
power supply providers. Until January 1, 2004, UI is required to offer full
"standard offer" electric service, under regulated rates, to all customers who
do not choose alternate power supply providers. The standard offer rates must be
at least 10% below the average prices in 1996. The standard offer rates must
include the price of generation, transmission and distribution services, the
competitive transition assessment, the systems benefits charge and the
conservation and renewable energy charges. Under current regulatory provisions,
UI's financial condition is not affected materially by whether customers choose
alternate suppliers to UI's standard offer electric service.

On December 28, 1999, UI and Enron Power Marketing, Inc. (EPMI) entered into a
Wholesale Power Supply Agreement, a PPA Entitlements Transfer Agreement and
related agreements documenting a four-year standard offer power supply
arrangement and the assumption of all of UI's long-term purchased power
agreements, effective January 1, 2000. Under these agreements, EPMI supplies the
generation services needed by UI to meet its standard offer obligations for the
four-year standard offer period at a fixed price. The agreements with EPMI also
include a financially settled contract for differences related to certain call
rights of EPMI and put rights of UI with respect to UI's entitlements in
Seabrook Unit 1 and in Millstone Unit 3, and UI's provision to EPMI of certain
ancillary products and services associated with those nuclear entitlements,
which provisions terminate at the earlier of December 31, 2003 or the date that
UI sells its nuclear interests. The agreements do not restrict UI's right to
sell to third parties UI's ownership interests in those nuclear generation units
or the generated energy actually attributable to its ownership interests.

The Restructuring Act requires that, in order for a Distribution Company to
recover any stranded costs associated with its power plants, its fossil-fueled
plants must be sold prior to 2000, with any net excess proceeds used to mitigate
its recoverable stranded costs, and UI must attempt to divest its ownership
interests in its nuclear-fueled power plants prior to 2004.

On April 16, 1999, UI sold both of its operating fossil-fueled generating
stations, Bridgeport Harbor Station and New Haven Harbor Station, to Wisvest
Corporation, a non-utility subsidiary of Wisconsin Energy Corporation based in
Milwaukee, Wisconsin. UI realized a book gain from the sale proceeds net of
taxes and plant investment. However, this gain was offset by a writedown of
other above-market generation costs, such as regulated plant costs and
tax-related regulatory assets or other costs related to the restructuring
transition, such that there was no net income effect of the sale. Net cash
proceeds from the sale were approximately $165 million.

On August 17, 2000, UI sold English Station (a deactivated non-nuclear
generating station, bordering the Mill River in New Haven) to Quinnipiac Energy
LLC (QE), a privately-owned independent power producer. QE intends to reactivate
the generating units at the station. Under the terms of the transaction, UI has
retained a permanent right of occupancy on and over the station property for
UI's existing New Haven harbor transmission line towers and cables. QE will
complete the bulkhead replacement project that UI has commenced to preserve and
protect the station property; and QE will assume responsibility for any and all
environmental liability associated with UI's prior ownership and operation of
the station. UI has agreed to pay for the cost of completing the bulkhead
replacement project and has funded 61% (approximately $1.2 million) of the
environmental remediation costs that will be incurred by QE under Connecticut's
Transfer Act as a result of QE's acquisition of the station. UI has also paid QE
$4.25 million for QE's assumption of the remaining Transfer Act remediation
costs and any and all environmental liability associated with UI's prior
ownership and operation of the station.

UIL HOLDINGS CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)

On October 1, 1998, in its "unbundling plan" filing with the DPUC under the
Restructuring Act, and in other regulatory dockets, UI stated that it plans to
divest its nuclear generation ownership and leasehold interests (17.5% of
Seabrook Unit 1 in New Hampshire and 3.685% of Millstone Station Unit 3 in
Connecticut) by the end of 2003, in accordance with the Restructuring Act. On
April 19, 2000, the DPUC approved UI's plan for divesting its ownership interest
in Millstone Unit 3 by participating in an auction process for all three of the
generating units at Millstone Station, which was concluded on August 7, 2000,
when Dominion Resources, Inc. agreed to purchase Millstone Units 1 and 2, and
93.47% of Millstone Unit 3 for $1.298 billion. The purchase price agreed to for
UI's ownership interest in Unit 3, which is subject to adjustments for
expenditures and eventualities prior to the date of closing on the sale, is
approximately $31 million, exclusive of nuclear fuel. UI's share of the proceeds
from the sale of the nuclear fuel inventory at the date of closing on the sale
is estimated to be approximately $2.5 million. The sale is scheduled to be
consummated on or about April 1, 2001 or as soon thereafter as all requisite
regulatory approvals are received. On December 15, 2000, UI and The Connecticut
Light and Power Company filed with the DPUC for its approval their plan to
divest their respective interests in Seabrook Unit 1 by an auction process. The
DPUC has commenced hearings on this divestiture plan.

The 1999 DPUC decision establishing UI's standard offer rates authorized UI to
recover $801 million of stranded costs through its rate structure.

Based on the decisions in the regulatory proceedings described above, the sale
of UI's fossil-generation assets and the planned divestiture of its nuclear
generation ownership interests by the end of 2003, UI ceased applying SFAS No.
71 to the generation portion of its assets and operations as of December 31,
1999. Based on the favorable DPUC decisions that allow full recovery, through
UI's rates, of all historically incurred stranded costs, UI did not record any
write-offs in connection with this event.

(D) ACCOUNTING FOR PHASE-IN PLAN

UI phased into rate base its allowable investment in Seabrook Unit 1, amounting
to $640 million, during the period January 1, 1990 to January 1, 1994. In
conjunction with this phase-in plan, UI was allowed to record a deferred return
on the portion of allowable investment excluded from rate base during the
phase-in period. UI amortized the net-of-tax accumulated deferred return of
$62.9 million over the five-year period that ended on December 31, 1999.

(E) SHORT-TERM CREDIT ARRANGEMENTS

On June 26, 2000, UI entered into a Money Market Loan arrangement with Chase
Manhattan Bank. On September 29, 2000, this arrangement was transferred to UIL
Holdings. This is an uncommitted short-term borrowing arrangement under which
Chase Manhattan Bank may make loans to UIL Holdings for fixed maturities from
one day up to six months. Chase Securities, Inc. acts as an agent and sells the
loans to investors. The fixed interest rates on the loans are determined based
on conditions in the financial markets at the time of each loan. As of December
31, 2000, UIL Holdings had loans totaling $59 million outstanding under this
arrangement.

UI's $60 million revolving credit agreement with a group of banks was terminated
on August 3, 2000. UI had no short-term borrowings outstanding under this
facility at that time.

UIL Holdings has a revolving credit agreement with the same group of banks,
which extends to August 2, 2001. The borrowing limit of this facility is $97.5
million. The facility permits UIL Holdings to borrow funds at a fluctuating
interest rate determined by the prime lending market in New York, and also
permits UIL Holdings to borrow money for fixed periods of time specified by UIL
Holdings at fixed interest rates determined by the Eurodollar interbank market
in London. If a material adverse change in the business, operations, affairs,
assets or condition, financial or otherwise, or

prospects of UIL Holdings and its subsidiaries, on a consolidated basis, should
occur, the banks may decline to lend additional money to UIL Holdings under this
revolving credit agreement, although borrowings outstanding at the time of such
an occurrence would not then become due and payable. As of December 31, 2000,
UIL Holdings had $50 million in short-term borrowings outstanding under this
facility.

The revolving credit agreement described above requires that UIL Holdings (i)
maintain a ratio of consolidated debt to consolidated capital, as of the last
day of each March, June, September and December, of not greater than 0.65 to
1.00; and (ii) shall not cause to exist debt of UIL Holdings (excluding debt of
its subsidiaries) to exceed $175 million in the aggregate principal amount
outstanding at any time. As of December 31, 2000, UIL Holdings' consolidated
debt to consolidated capital ratio was 0.58 and its aggregate principal debt
outstanding (excluding debt of its subsidiaries) was $173.7 million (including
intercompany loans to UIL Holdings).

Information with respect to short-term borrowings under the UIL Holdings' Money
Market Loan arrangement and revolving credit agreement and the UI revolving
credit agreement is as follows:

2000 1999 1998
---- ---- ----
(000's)
Maximum aggregate principal amount of
short-term borrowings outstanding at

*Average short-term borrowings represent the sum of daily borrowings
outstanding, weighted for the number of days outstanding and divided by the
number of days in the period. The weighted average interest rate is determined
by dividing interest expense by the amount of average borrowings. Fees of
approximately $386,000, $291,000 and $381,000 paid during 2000, 1999 and 1998,
respectively, are excluded from the calculation of the weighted average interest
rate.

were as follows: tax liabilities on book/tax plant basis differences and on the
cumulative amount of income taxes on temporary differences previously flowed
through to ratepayers, $194 million; tax liabilities on normalization of
book/tax depreciation timing differences, $122 million and tax assets on the
disallowance of plant costs, $35 million.

(H) PENSION AND OTHER BENEFITS

UI's qualified pension plan, which is based on the highest three years of pay,
covers substantially all of its employees, the employees of APS, and certain
management employees of URI and Xcelecom. UI also has a non-qualified
supplemental plan for certain executives and a non-qualified retiree only plan
for certain early retirement benefits. The net pension credit to income for
these plans for 2000, 1999 and 1998 was $14.7 million, $8.0 million, and $5.1
million, respectively.

Funding policy for the qualified plan is to make annual contributions that
satisfy the minimum funding requirements of ERISA but that do not exceed the
maximum deductible limits of the Internal Revenue Code. These amounts are
determined each year as a result of an actuarial valuation of the plan. In 1998,
$2.6 million was contributed for 1998 funding requirements. No contributions
were made in 1999. In 2000, $2.5 million was contributed for 1999 funding
requirements. UI has established a supplemental retirement benefit trust and
through this trust purchased life insurance policies on the officers of UI to
fund the future liability under the supplemental plan. The cash surrender value
of these policies is shown as an investment on the Consolidated Balance Sheet.

In addition to providing pension benefits, UI also provides other postretirement
benefits (OPEB), consisting principally of health care and life insurance
benefits, for retired employees and their dependents. Employees whose sum of age
and years of service at time of retirement is equal to or greater than 85 (or
who are 62 with at least 20 years of service) are eligible for benefits
partially subsidized by UI. The amount of benefits subsidized by UI is
determined by age and years of service at retirement.

For funding purposes, UI established a Voluntary Employees' Benefit Association
Trust (VEBA) to fund OPEB for UI's union employees. Approximately 45% of UI's
employees are represented by Local 470-1, Utility Workers Union of America,
AFL-CIO, for collective bargaining purposes. UI established a 401(h) account in
connection with the qualified pension plan to fund OPEB for UI's non-union
employees who retire on or after January 1, 1994. The funding policy assumes
contributions to these trust funds to be the total OPEB expense calculated under
SFAS No. 106, adjusted to reflect a share of amounts expensed as a result of
voluntary early retirement programs minus pay-as-you-go benefit payments for
pre-January 1, 1994 non-union retirees, allocated in a manner that minimizes
current income tax liability, without exceeding maximum tax deductible limits.
In accordance with this policy, UI did not make contributions to the union VEBA
in 2000, 1999 and 1998. UI contributed $0.2 million to the 401(h) account in
2000. UI did not make a contribution to the 401(h) account in 1999 and
contributed $0.9 million to the 401(h) account in 1998. Plan assets for both the
union VEBA and 401(h) account consist primarily of equity and fixed-income
securities.

The following table represents the plans' beginning benefit obligation balance
reconciled to the ending benefit obligation balance, beginning fair value of
plan assets balance reconciled to the ending fair value of plan assets balance
and the respective funded status reconciled to the Consolidated Balance Sheet.

UI has a 401(k)/Employee Stock Ownership Plan (KSOP) in which substantially all
of its employees, the employees of APS, and certain management employees of URI
and Xcelecom are eligible to participate. The KSOP enables employees to defer
receipt of up to 15% of their compensation and to invest such funds in a number
of investment alternatives. Matching contributions are made to the KSOP, in the
form of UIL Holdings' common stock, based on each employee's salary deferrals in
the KSOP. The matching contribution currently equals fifty cents for each dollar
of the employee's compensation deferred, but is not more than 3 3/8% of the
employee's annual salary. Matching contributions to the KSOP during 2000, 1999
and 1998 were $1.8 million, $1.5 million and $1.7 million, respectively.

UIL Holdings pays dividends on the shares of stock in the KSOP to the
participant and UIL Holdings receives a tax deduction for the dividends paid.
Contributions are made to the KSOP equal to 25% of the dividends paid to each
participant. Annual contributions during 2000, 1999 and 1998 were $293,000,
$319,000 and $270,000, respectively.

(1) Of the plant investment amounts, $456 million for Seabrook Unit 1 and $62
million for Millstone Unit 3 are reflected on the consolidated balance
sheet as regulatory assets.

UI's share of the operating costs of jointly owned plants is included in the
appropriate expense captions in the Consolidated Statement of Income.

(J) UNAMORTIZED CANCELLED NUCLEAR PROJECT

From December 1984 through December 1992, UI had been recovering its investment
in Seabrook Unit 2, a partially constructed nuclear generating unit that was
cancelled in 1984, over a regulatory approved ten-year period without a return
on its unamortized investment. In the 1992 rate decision, the DPUC adopted a
proposal by UI to write off its remaining investment in Seabrook Unit 2,
beginning January 1, 1993, over a 24-year period, corresponding with the
flowback of certain Connecticut Corporation Business Tax (CCBT) credits. Such
decision will allow UI to retain the Seabrook Unit 2/CCBT amounts for ratemaking
purposes, with the accumulated CCBT credits not deducted from rate base during
the 24-year period of amortization in recognition of a longer period of time for
amortization of the Seabrook Unit 2 balance. As a result of reducing its
remaining unamortized investment in Seabrook Unit 2 with proceeds from the sale
of certain Seabrook Unit 2 equipment, UI expects to completely amortize its
unamortized investment in the year 2007.

(K) LEASE OBLIGATIONS

UIL Holdings has lease arrangements for data processing equipment, office
equipment, vehicles and office space, including the lease of a distribution
service facility, which is recognized as a capital lease. The gross amount of
assets recorded under capital leases and the related obligations of those leases
as of December 31, 2000 are recorded on the Consolidated Balance Sheet.

Future minimum lease payments under capital leases, excluding the Seabrook
sale/leaseback transaction, which is being treated as a long-term financing, are
estimated to be as follows:

Capitalization of leases on UI's books has no impact on income, since the sum of
the amortization of a leased asset and the interest on the lease obligation
equals the rental expense allowed for ratemaking purposes.

Operating leases, which are charged to operating expense, consist principally of
lease of office space and facilities and a wide variety of equipment. The most
significant operating lease is that of UI's corporate headquarters. The future
minimum lease payments under these operating leases is estimated to be as
follows:

NUCLEAR INSURANCE CONTINGENCIES

The Price-Anderson Act, currently extended through August 1, 2002, limits public
liability resulting from a single incident at a nuclear power plant. The first
$200 million of liability coverage is provided by purchasing the maximum amount
of commercially available insurance. Additional liability coverage will be
provided by an assessment of up to $83.9 million per incident, levied on each of
the nuclear units licensed to operate in the United States, subject to a maximum
assessment of $10 million per incident per nuclear unit in any year. In
addition, if the sum of all public liability claims and legal costs resulting
from any nuclear incident exceeds the maximum amount of financial protection,
each reactor operator can be assessed an additional 5% of $83.9 million, or $4.2
million. The maximum assessment is adjusted at least every five years to reflect
the impact of inflation. With respect to each of the two operating nuclear
generating units in which UI has an interest, UI will be obligated to pay its
ownership and/or leasehold share of any statutory assessment resulting from a
nuclear incident at any nuclear generating unit. Based on its interests in these
nuclear generating units, UI estimates its maximum liability would be $17.8
million per incident. However, any assessment would be limited to $2.1 million
per incident per year.

The Nuclear Regulatory Commission requires each operating nuclear generating
unit to obtain property insurance coverage in a minimum amount of $1.06 billion
and to establish a system of prioritized use of the insurance proceeds in the
event of a nuclear incident. The system requires that the first $1.06 billion of
insurance proceeds be used to stabilize the nuclear reactor to prevent any
significant risk to public health and safety and then for decontamination and
cleanup operations. Only following completion of these tasks would the balance,
if any, of the segregated insurance proceeds become available to the unit's
owners. For each of the two operating nuclear generating units in which UI has
an interest, UI is required to pay its ownership and/or leasehold share of the
cost of purchasing such insurance. Although each of these units has purchased
$2.75 billion of property insurance coverage, representing the limits of


- 62 -

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)

coverage currently available from conventional nuclear insurance pools, the cost
of a nuclear incident could exceed available insurance proceeds. Under those
circumstances, the nuclear insurance pools that provide this coverage may levy
assessments against the insured owner companies if pool losses exceed the
accumulated funds available to the pool. The maximum potential assessments
against UI with respect to losses occurring during current policy years are
approximately $2.4 million.

OTHER COMMITMENTS AND CONTINGENCIES

CONNECTICUT YANKEE

On December 4, 1996, the Board of Directors of the Connecticut Yankee Atomic
Power Company (Connecticut Yankee) voted unanimously to retire the Connecticut
Yankee nuclear plant (the Connecticut Yankee Unit) from commercial operation. UI
has a 9.5% stock ownership share in Connecticut Yankee. The power purchase
contract under which UI had purchased its 9.5% entitlement to the Connecticut
Yankee Unit's power output permits Connecticut Yankee to recover 9.5% of all of
its costs from UI. In December of 1996, Connecticut Yankee filed decommissioning
cost estimates and amendments to the power contracts with its owners with the
Federal Energy Regulatory Commission (FERC). Based on regulatory precedent, this
filing requested confirmation that Connecticut Yankee will continue to collect
from its owners its decommissioning costs, the unrecovered investment in the
Connecticut Yankee Unit and other costs associated with the permanent shutdown
of the Connecticut Yankee Unit. On April 7, 2000, Connecticut Yankee reached a
settlement agreement with the DPUC and the Connecticut Office of Consumer
Counsel (two of the intervenors in the FERC proceeding). This agreement was
submitted to the FERC, which approved it in all respects on July 26, 2000; and
it became effective on August 1, 2000. The agreement allows Connecticut Yankee
to earn a return on equity of 6% and stipulates a new decommissioning cost
estimate for the Connecticut Yankee Unit for purposes of FERC-approved
decommissioning cost collections by Connecticut Yankee through the power
contracts with the unit's owners.

UI's estimate of its remaining share of Connecticut Yankee costs, including
decommissioning, less return of investment (approximately $7.1 million) and
return on investment (approximately $1.6 million) at December 31, 2000, is
approximately $17.2 million. This estimate, which is subject to ongoing review
and revision, has been recorded as an obligation and a regulatory asset on the
Consolidated Balance Sheet.

HYDRO-QUEBEC

UI is a participant in the Hydro-Quebec transmission intertie facility linking
New England and Quebec, Canada. Phase I of this facility, which became
operational in 1986 and in which UI has a 5.45% participating share, has a 690
megawatt equivalent generation capacity value; and Phase II, in which UI has a
5.45% participating share, increased the equivalent generation capacity value of
the intertie from 690 megawatts to a maximum of 2000 megawatts in 1991. UI is
obligated to furnish a guarantee for its participating share of the debt
financing for the Phase II facility. As of December 31, 2000, UI's guarantee
liability for this debt was approximately $5.6 million.

LONG ISLAND CABLE PROJECT

United Capital Investments (UCI), an indirect wholly-owned subsidiary of UIL
Holdings, has a 25% interest in a merchant electric transmission line project
that proposes to install, own and operate a 330-megawatt transmission line
connecting Connecticut and Long Island under Long Island Sound. UCI is obligated
to furnish a direct guarantee by means of a letter of credit for its
participating share of the debt financing of the project. Under separate
agreement, UIL Holdings is an indirect guarantor of the obligation of UCI. As of
December 31, 2000, UCI's guarantee liability for this debt was approximately
$7.7 million.

ENVIRONMENTAL CONCERNS

In complying with existing environmental statutes and regulations and further
developments in areas of environmental concern, including legislation and
studies in the fields of water quality, hazardous waste handling and disposal,
toxic substances, and electric and magnetic fields, UIL Holdings may incur
substantial capital expenditures for equipment modifications and additions,
monitoring equipment and recording devices, and it may incur additional
operating expenses. The total amount of these expenditures is not now
determinable.

SITE DECONTAMINATION, DEMOLITION AND REMEDIATION COSTS

UI has estimated that the total cost of decontaminating and demolishing its
Steel Point Station and completing requisite environmental remediation of the
site will be approximately $11.3 million, of which approximately $8.7 million
had been incurred as of December 31, 2000, and that the value of the property
following remediation will not exceed $6.0 million. As a result of a 1992 DPUC
retail rate decision, beginning January 1, 1993, UI has been recovering through
retail rates $1.075 million of the remediation costs per year. The remediation
costs, property value and recovery from customers will be subject to true-up in
UI's next retail rate proceeding based on actual remediation costs and actual
gain on UI's disposition of the property.

UI has begun replacing the bulkhead surrounding a site, bordering the Mill River
in New Haven, that contains transmission facilities and deactivated generation
facilities, at an estimated cost of $13.5 million. Of this amount, $4.2 million
represents the portion of the costs to protect UI's transmission facilities and
will be capitalized as plant in service. The remaining estimated cost of $9.3
million was expensed in 1999. UI has conveyed to an unaffiliated entity,
Quinnipiac Energy LLC (QE), this entire site, reserving to UI permanent
easements for the operation of its transmission facilities on the site. QE will
complete the bulkhead replacement project at UI's expense. UI has also funded
61% (approximately $1.2 million) of the environmental remediation costs that
will be incurred by QE to bring the site into compliance with applicable
Connecticut minimum standards. QE intends to reactivate the generation
facilities on the site as a merchant electric generating plant.

As described at Note (C), "Rate-Related Regulatory Proceedings," UI closed on
the sale of its Bridgeport Harbor Station and New Haven Harbor Station
generating plants in compliance with Connecticut's electric utility industry
restructuring legislation on April 16, 1999. Environmental assessments performed
in connection with the marketing of these plants indicate that substantial
remediation expenditures will be required in order to bring the plant sites into
compliance with applicable Connecticut minimum standards. The purchaser of the
plants has agreed to undertake and pay for the major portion of this
remediation. However, UI will be responsible for remediation of the portions of
the plant sites that have been retained by it.

(M) NUCLEAR FUEL DISPOSAL AND NUCLEAR PLANT DECOMMISSIONING

Costs associated with nuclear plant operations include amounts for disposal of
nuclear wastes, including spent fuel, and for the ultimate decommissioning of
the plants. Under the Nuclear Waste Policy Act of 1982, the federal Department
of Energy (DOE) is required to design, license, construct and operate a
permanent repository for high level radioactive wastes and spent nuclear fuel.
The Act requires the DOE to provide for the disposal of spent nuclear fuel and
high level radioactive waste from commercial nuclear plants through contracts
with the owners and generators of such waste; and the DOE has established
disposal fees that are being paid to the federal government by electric
utilities owning or operating nuclear generating units. In return for payment of
the prescribed fees, the federal government was required to take title to and
dispose of the utilities' high level wastes and spent nuclear fuel beginning no
later than January 1998. However, the DOE has announced that its first high
level waste repository will not be in operation earlier than 2010, and possibly
not earlier than 2013, and that, absent a repository, the DOE has no statutory
obligation to begin taking high level wastes and spent nuclear fuel for disposal
by January 1998. However, numerous utilities and states have


- 64 -


UIL HOLDINGS CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)

obtained a judicial declaration that the DOE has a statutory responsibility to
take title to and dispose of high level wastes and spent nuclear fuel beginning
in January 1998, and that the contracts between the DOE and the plant owners and
generators of such waste will provide a potentially adequate remedy to owners
and generators in monetary damages for breach of the contracts. The DOE is
contesting these judicial declarations; and it is unclear at this time whether
the United States Congress will enact legislation to address spent fuel/high
level waste disposal issues.

Until the federal government begins receiving such materials, nuclear generating
units will need to retain high level wastes and spent nuclear fuel on-site or
make other provisions for their storage. Storage facilities for the Connecticut
Yankee Unit are deemed adequate, and storage facilities for Millstone Unit 3 are
expected to be adequate for the projected life of the unit. Storage facilities
for Seabrook Unit 1 are expected to be adequate until at least 2010. Fuel
consolidation and compaction technologies are being considered for Seabrook Unit
1 and may provide adequate storage capability for the projected life of the
unit. In addition, other licensed technologies, such as dry storage casks, may
satisfy spent nuclear fuel storage requirements.

Disposal costs for low-level radioactive wastes (LLW) that result from operation
or decommissioning of nuclear generating units decreased in 1999, as a result of
negotiations between the generators of such wastes and the owners of licensed
disposal facilities. Currently, the Chem Nuclear LLW facility at Barnwell, South
Carolina, is open to the Connecticut Yankee Unit, Millstone Unit 3, and Seabrook
Unit 1 for disposal of LLW. The Envirocare LLW facility at Clive, Utah, is also
open to these generating units for portions of their LLW. All three units have
contracts in place for LLW disposal at these disposal facilities.

Because access to a LLW disposal facility may be interrupted at any time,
Seabrook Unit 1 and Millstone Unit 3 have storage plans that will allow on-site
retention of LLW for at least five years in the event that disposal is
interrupted. The Connecticut Yankee Unit, which has been retired from commercial
operation, has a similar storage program, although disposal of its LLW is taking
place in connection with its decommissioning.

The State of New Hampshire has not met deadlines for compliance with the
Low-Level Radioactive Waste Policy Act and has stated that the state is
unsuitable for a LLW disposal facility. New Hampshire is pursuing other options
for out-of-state disposal of LLW. Connecticut, New Jersey and South Carolina
have formed the Atlantic Compact, which should ensure that the Connecticut
Yankee Unit and Millstone Unit 3 will have access to the Chem Nuclear LLW
facility at Barnwell, South Carolina, through the end of their decommissioning.

NRC licensing requirements and restrictions are also applicable to the
decommissioning of nuclear generating units at the end of their service lives,
and the NRC has adopted comprehensive regulations concerning decommissioning
planning, timing, funding and environmental reviews. UI and the other owners of
the nuclear generating units in which UI has interests estimate decommissioning
costs for the units and attempt to recover sufficient amounts through their
allowed electric rates, together with earnings on the investment of funds so
recovered, to cover expected decommissioning costs. Changes in NRC requirements
or technology, as well as inflation, can increase estimated decommissioning
costs.

New Hampshire has enacted a law requiring the creation of a government-managed
fund to finance the decommissioning of nuclear generating units in that state.
The New Hampshire Nuclear Decommissioning Financing Committee (NDFC) has
established $609.3 million (in 2001 dollars) as the decommissioning cost
estimate for Seabrook Unit 1, of which UI's share would be approximately $107
million. This estimate assumes the prompt removal and dismantling of the unit at
the end of its estimated 36-year energy producing life. Monthly decommissioning
payments are being made to the state-managed decommissioning trust fund. UI's
share of the decommissioning payments made during 2000 was $3.4 million. UI's
share of the fund at December 31, 2000 was approximately $24.2 million.



- 65 -


UIL HOLDINGS CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)

Connecticut has enacted a law requiring the operators of nuclear generating
units to file periodically with the DPUC their plans for financing the
decommissioning of the units in that state. The current decommissioning cost
estimate for Millstone Unit 3 is $648 million (in 2001 dollars), of which UI's
share would be approximately $24 million. This estimate assumes the prompt
removal and dismantling of the unit at the end of its estimated 40-year energy
producing life. Monthly decommissioning payments, based on these cost estimates,
are being made to a decommissioning trust fund managed by Northeast Utilities
(NU). UI's share of the Millstone Unit 3 decommissioning payments made during
2000 was $0.6 million. UI's share of the fund at December 31, 2000 was
approximately $8.6 million. The current decommissioning cost estimate for the
Connecticut Yankee Unit, assuming the prompt removal and dismantling of the
unit, is $393 million, of which UI's share would be $37 million. Through
December 31, 2000, $244 million has been expended for decommissioning. The
projected remaining decommissioning cost is $149 million, of which UI's share
would be $14 million. The decommissioning trust fund for the Connecticut Yankee
Unit is also managed by NU. For UI's 9.5% equity ownership in Connecticut
Yankee, decommissioning costs of $2.4 million were funded by UI during 2000, and
UI's share of the fund at December 31, 2000 was $16 million.

The Financial Accounting Standards Board (FASB) expects to issue a revised
exposure draft related to the accounting for the closure and removal costs of
long-lived assets, including nuclear plant decommissioning. If the proposed
accounting standard were adopted, it may result in higher annual provisions for
decommissioning to be recognized earlier in the operating life of nuclear units
and an accelerated recognition of the decommissioning obligation. The FASB will
be deliberating this issue, and the resulting final pronouncement is not
expected to be effective prior to 2002.
