ITEM 1.  BUSINESS.

INTRODUCTION

     BayCorp Holdings, Ltd. ("BayCorp" or the "Company") is a holding company
incorporated in Delaware in 1996. BayCorp owns two subsidiaries that generate
and trade wholesale electricity, Great Bay Power Corporation ("Great Bay") and
Little Bay Power Corporation ("Little Bay"), each of which is wholly-owned as of
December 31, 2001. In addition, BayCorp owns 45.9% of HoustonStreet Exchange,
Inc. ("HoustonStreet"), an Internet-based independent crude oil and refined
products trading exchange.

     Great Bay and Little Bay are electric generating and trading companies.
Their principal asset is a combined 15% joint ownership interest in the Seabrook
Nuclear Power Project in Seabrook, New Hampshire (the "Seabrook Project" or
"Seabrook"). This ownership interest entitles the companies to approximately 174
megawatts ("MWs") of the Seabrook Project's power output. Great Bay and Little
Bay are exempt wholesale generators ("EWGs") under the Public Utility Holding
Company Act of 1935 ("PUHCA"). Unlike regulated public utilities, Great Bay and
Little Bay have no franchise area or captive customers. The companies sell their
power in the competitive wholesale power markets.

     Great Bay was incorporated in New Hampshire in 1986 and was formerly known
as EUA Power Corporation. Little Bay was incorporated in New Hampshire in 1998.
Great Bay sells its power, including its 12.1% share and Little Bay's 2.9% share
of the electricity output of the Seabrook Project, in the wholesale electricity
market, primarily in the Northeast United States. Little Bay sells its power
solely to Great Bay under an intercompany agreement. Neither BayCorp nor its
subsidiaries have operational responsibilities for the Seabrook Project. Great
Bay currently sells all but approximately 10 MWs of its share of the Seabrook
Project capacity in the wholesale short-term market. In addition to selling its
power generated by Seabrook, Great Bay purchases power on the open market for
resale to third parties.

     Little Bay purchased a 2.9% interest in the Seabrook Project in November
1999 from Montaup Electric Company ("Montaup"), a subsidiary of Eastern
Utilities Associates ("EUA"), for a purchase price of $3.2 million, plus
approximately $1.7 million for certain prepaid items, primarily nuclear fuel and
capital expenditures. In addition, Montaup prefunded the decommissioning
liability associated with Little Bay's 2.9% share of Seabrook by transferring
approximately $12.4 million into Little Bay's decommissioning account, an
irrevocable trust earmarked for Little Bay's share of Seabrook Project
decommissioning expenses.

     HoustonStreet was incorporated in Delaware in 1999. HoustonStreet is an
equity investment of BayCorp. HoustonStreet developed and operates
HoustonStreet.com, an Internet-based independent crude oil and refined products
trading exchange in the United States.

RECENT DEVELOPMENTS

     In October 2000, the Company announced that it reached an agreement with
Northeast Utilities ("NU") under which the Company's generating subsidiaries,
Great Bay and Little Bay, will include their aggregate 15% ownership share of
the Seabrook Project in the current auction of NU's subsidiaries' shares of the
Seabrook Project. Under the terms of the agreement, BayCorp will receive the
sales price established by the auction process. In the event that the sale
yields proceeds for BayCorp of more than $87.2 million, BayCorp and NU will
share the excess proceeds. Should BayCorp's sales proceeds be less than $87.2
million, NU will make up the difference below that amount on a dollar for dollar
basis up to a maximum of $17.4 million. Under the agreement, BayCorp will be
paid separately for nuclear fuel and inventory. The agreement also limits any
top-off amount required to be funded by BayCorp for decommissioning as part of
the sale process at the amount required by the Nuclear Regulatory Commission
("NRC") regulations.

     In October 2001, the Company announced that the New Hampshire Public
Utilities Commission ("NHPUC") and the Connecticut Department of Public Utility
Control ("CDPUC") selected J.P. Morgan as their financial advisor for the sale
of ownership interests in the Seabrook Project. J.P. Morgan will manage the sale
under the oversight of the NHPUC and the CDPUC. J.P. Morgan managed the recent
sales of the
<PAGE>

Millstone Connecticut and Vermont Yankee nuclear plants. In December 2001, the
NHPUC, in coordination with the CDPUC, announced the start of the auction of
88.2% of the ownership shares of the Seabrook Project. The Company anticipates
the closing of the sale in the fourth quarter of 2002.

     With continued uncertainty about the possibility of additional terrorist
activities in the United States, the Nation's nuclear power plants, including
the Seabrook Project, remain at a high level of security. Immediately after the
attacks in New York and Washington D.C. on September 11, 2001, management of the
Seabrook Project activated enhanced security measures. On February 25, 2002, the
NRC issued an order to all nuclear plant licensees, requiring them to take
certain additional interim compensatory measures to address the generalized
high-level threat environment. These additional compensatory requirements will
provide the NRC with reasonable assurance that public health and safety and the
common defense and security continue to be adequately protected in the current
generalized high-level threat environment. These requirements will remain in
effect pending notification from the NRC that a significant change in the threat
environment occurs, or until the NRC determines that other changes are needed
following a more comprehensive reevaluation of current safeguards and security
programs. Seabrook remains at a high level of security and the management of
Seabrook has assured the joint owners of Seabrook that they will take actions
necessary to comply with the NRC order setting out the requirements for interim
compensatory measures. Compliance with these requirements will result in
additional incremental operating and capital costs, a prorated portion of which
will be paid by Great Bay and Little Bay. Should additional security measures be
required by the NRC, additional operating or capital costs could be incurred at
the Seabrook Project.

     On January 4, 2002, BayCorp reported that Great Bay received notice on
December 21, 2001 from Enron Power Marketing, Inc. ("Enron") that Enron was
terminating its contracts with Great Bay. Enron owes Great Bay $1,075,200 for
power delivered prior to Enron's Chapter 11 bankruptcy filing on December 2,
2001. Great Bay also had an administrative claim against Enron of $684,100 for
power delivered between December 2, 2001 and December 21, 2001 and an
unliquidated claim for damages resulting from the termination of the contracts.
Enron paid $684,100 to Great Bay on February 21, 2002. During the fourth quarter
of 2001, BayCorp recorded an expense of $1,100,000 to establish a reserve for
doubtful accounts due to the uncertainty of collecting remaining amounts owed by
Enron to Great Bay for power delivered prior to Enron's Chapter 11 bankruptcy
filing.

     The Company owned 100% of HoustonStreet as of December 31, 1999.
HoustonStreet sold capital stock in 2000 to outside investors and as a result,
as of December 4, 2000, the Company's ownership fell below 50%, to 45.9%.
Subsequently, the Company deconsolidated HoustonStreet as of December 4, 2000
and started accounting for this investment on the equity method.

     On March 30, 2001, HoustonStreet raised approximately $2.9 million in
additional funding, including $450,000 from BayCorp, by selling senior secured
notes, warrants to purchase HoustonStreet preferred stock and warrants to
purchase HoustonStreet common stock. Collectively, these securities are referred
to as the "HoustonStreet Series C Units." In April 2001, BayCorp authorized
HoustonStreet to convert BayCorp's $7,000,000 loan made in 2000, along with
approximately $1,000,000 in accrued interest and penalties on the note and past
due management fees, into $8,000,000 of Series C Units. The loan, accrued
interest and receivables from HoustonStreet had been written down to zero as of
December 31, 2000 and as such, the conversion of these amounts had no accounting
impact on BayCorp.

     In 2001, HoustonStreet downsized its organization and is focusing its
efforts on its crude oil and refined products trading platforms. HoustonStreet
shut down its electricity-trading platform in the second half of 2001.

CURRENT BUSINESS

     BayCorp's principal wholesale electricity generation and trading assets are
its 100% equity interests in Great Bay and Little Bay. The business of Great Bay
and Little Bay consists of managing their joint ownership interests in the
Seabrook Project and the sale in the wholesale power market of their share of
electricity produced by the Seabrook Project. Neither Great Bay nor Little Bay
has operational responsibility for the Seabrook Project. Great Bay is a party to
one long-term power contract for approximately 10 MW of Great
                                        2
<PAGE>

Bay's share of the Seabrook Project capacity. Great Bay is also a party to a
contract with Little Bay to purchase all of the output from the portion of
Seabrook owned by Little Bay. This contract is renewed annually, most recently
in November 2001. See "--Purchased Power Agreements." Great Bay's business
strategy is to utilize unit contingent and historically, firm forward sales
contracts, to maximize the value of its 174 MW power supply from the Seabrook
Project.

     Traditionally, Great Bay sold most of its share of the Seabrook Project
electricity output under unit contingent contracts. Under unit contingent
contracts, Great Bay is obligated to provide the buyer with power only when the
Seabrook Project is operating. In late 1998, Great Bay began to sell some of its
electricity as firm power, which entitles the buyer to electricity whether or
not the Seabrook Project is operating. Buyers pay a premium for firm power over
unit contingent power because they can rely on uninterrupted electricity. In
order to supply firm power during unscheduled outages at the Seabrook Project,
Great Bay purchases power from the spot market during these outages and resells
that power to its firm power customers. Spot market sales are subject to price
fluctuations based on the relative supply and demand of electricity. As a result
of spot market power price fluctuations, Great Bay has had to purchase power at
prices exceeding prices paid by Great Bay's firm power customers during outages.
Although Great Bay bore the primary risk of these price fluctuations, Great Bay
maintained insurance in 2000 and 2001 to protect Great Bay during periods of
extreme price volatility, subject to certain deductibles and coverage limits. In
December 2001, Great Bay cancelled this insurance. Great Bay has not entered
into any firm power contracts for 2002 given the expected sale of the Seabrook
Project in 2002.

  The Seabrook Project

     The Seabrook Project is located on an 896-acre site in Seabrook, New
Hampshire. It is owned by Great Bay, Little Bay and nine other utility
companies, consisting of North Atlantic Energy Company, Connecticut Light and
Power, The United Illuminating Company, Canal Electric Company, Massachusetts
Municipal Wholesale Electric Company, New England Power Company, New Hampshire
Electric Cooperative, Inc., Taunton Municipal Lighting Plant and Hudson Light &
Power Department (together with Great Bay and Little Bay, the "Participants").

     Seabrook Unit 1 is a 1,150-MW nuclear-fueled steam electricity generating
station. It employs a four loop, pressurized water reactor and support auxiliary
systems designed by the Westinghouse Electric Company. The reactor is housed in
a steel-lined reinforced concrete containment structure and a concrete
containment enclosure structure. Reactor cooling water is obtained from the
Atlantic Ocean through a 17,000-foot-long intake tunnel and returned through a
16,500-foot-long discharge tunnel. The station has a remaining expected license
life of 24 years. Seabrook Unit 1 transmits its generated power to the New
England 345 kilovolt transmission grid, a major network of interconnecting lines
covering New England, through three separate transmission lines emanating from
the station. On March 15, 1990, the Participants received a full power operating
license from the NRC that authorizes operation of Seabrook Unit 1 until October
2026. Commercial operation of Seabrook Unit 1 commenced on August 19, 1990.
Management believes that Seabrook Unit 1 is in good condition.

     Since the Seabrook Project was originally designed to consist of two
generating units, Great Bay and Little Bay also own a combined 15% joint
ownership interest in Seabrook Unit 2. Great Bay and Little Bay assigned no
value to Seabrook Unit 2 because on November 6, 1986, the joint owners of the
Seabrook Project voted to dispose of Unit 2. Thereafter, Great Bay wrote off its
investment in Unit 2. Little Bay has no investment in Unit 2. Certain assets of
Seabrook Unit 2 have been sold from time to time to third parties. However,
there have been no material sales of Unit 2 assets since July 1996.

     Because Seabrook Unit 2 was never completed or operated, costs associated
with its disposition are not included in the amounts collected for the
decommissioning of Unit 1 and the common facilities. Great Bay and Little Bay
currently pay their share of monthly expenses required to preserve and protect
the value of the Seabrook Unit 2 components. The Company anticipates that
Seabrook Unit 2 will be sold as part of the expected sale of the Seabrook
Project in 2002. The Participants in Seabrook Unit 1 and Unit 2 have agreed to
contribute their pro-rata share of $2 million to an escrow account for the
development and performance of a

                                        3
<PAGE>

plan to mitigate the visual impact of Unit 2. The contribution to the escrow
account is scheduled to occur within 60 days of the closing of the sale of
Seabrook.

  Joint Ownership of Seabrook

     Great Bay, Little Bay and the other Participants are parties to the
Agreement for Joint Ownership, Construction and Operation of New Hampshire
Nuclear Units (the "JOA"), which establishes the respective ownership interests
of the Participants in the Seabrook Project and defines their responsibilities
with respect to the ongoing operation, maintenance and decommissioning of the
Seabrook Project. In general, all ongoing costs of the Seabrook Project are
divided proportionately among the Participants in accordance with their
ownership interests in the Seabrook Project. Ownership interests in the Seabrook
Project are several and not joint, and each Participant is only liable for its
share of the Seabrook Project's costs and not liable for any other Participant's
share. Great Bay and Little Bay's combined joint ownership interest of 15% is
the third largest interest among the Participants, exceeded only by the
approximately 40% interest held by Northeast Utilities ("NU") and its affiliates
and the 17.5% interest held by The United Illuminating Company.

     A Participant may sell any portion of its ownership interest to any entity
that is engaged in the electric utility business in New England. Before such
sale, however, such selling Participant must give certain other Participants the
right of first refusal to purchase the interest on the same terms. Any
Participant may transfer, free from the foregoing right of first refusal, any
portion of its interest (a) to a wholly-owned subsidiary, (b) to another company
in the same holding company system or a construction trust for the benefit of
the transferor or another company in the same holding company system, or (c) in
connection with a merger, consolidation or acquisition of substantially all of
the properties or all of the generating facilities of a Participant. Eight
Participants have announced that they are selling their ownership interest in
the Seabrook Project as part of the current sale process underway.

     The failure to make monthly payments under the JOA by owners of the
Seabrook Project other than Great Bay and Little Bay may have a material effect
on Great Bay and Little Bay if either should choose to pay a greater proportion
of the Seabrook Unit 1 and Seabrook Unit 2 expenses in order to preserve the
value of its share of the Seabrook Project. In the past, certain of the owners
of the Seabrook Project other than Great Bay and Little Bay have not made their
full respective payments. At the current time, the electric utility industry is
undergoing significant changes as competition and deregulation have been
introduced into the marketplace. If a Participant other than Great Bay or Little
Bay filed for bankruptcy, and that Participant was unable to pay its share of
Seabrook Project expenses, Great Bay and/or Little Bay might choose to pay a
greater portion of Seabrook Project expenses. In the past, the filing of
bankruptcy by a Participant has not resulted in a failure to pay Seabrook
Project expenses or an increase in the percentage of expenses paid by other
Participants.

     The JOA provides for a Managing Agent to carry out the daily operational
and management responsibilities of the Seabrook Project. The current Managing
Agent, appointed by certain of the Participants on June 29, 1992, is North
Atlantic Energy Service Corporation ("NAESCO"), a wholly-owned subsidiary of NU.
NU, in conjunction with certain of its affiliates, holds the largest joint
ownership interest in the Seabrook Project, as described above. Certain material
decisions regarding the Seabrook Project are made by an Executive Committee
consisting of the chief executive officers of certain of the Participants or
their designees. There are currently five members of the Executive Committee.
The Executive Committee acts by a majority vote of its members, although any
action of the Executive Committee may be modified by a vote of 51% of the
ownership interests. Frank W. Getman Jr., the Company's President and Chief
Executive Officer, is currently a member of the Executive Committee. Anthony M.
Callendrello, the Company's Chief Operating Officer, is a member of the Audit
Committee and is Chairperson of the Budget Subcommittee and Vice Chairperson of
the Non-Operating Participants Committee. Under the JOA, the managing agent of
the Seabrook Project may be removed and a new managing agent appointed by a 51%
interest of the Participants.

                                        4

  Marketing and Customers

     Great Bay currently sells most of its power in the Northeast United States
in the short-term wholesale power market. Great Bay does not currently depend on
any single customer because a number of utilities and marketers are willing to
buy Great Bay's share of electricity from the Seabrook Project at substantially
the same price. Prices in the short-term market are typically higher during the
summer and winter because the demand for electrical power is higher during these
periods in the Northeast United States. The Company utilized unit contingent and
firm forward energy trading contracts to maximize the value of the uncommitted
portion of its 174-megawatt power supply from the Seabrook Project in 2001. The
Company was not a party to any firm forward energy trading contracts as of
December 31, 2001. Similarly, the Company does not expect to enter into firm
forward energy trading contracts in 2002, in light of its expected sale of its
ownership interest in the Seabrook Project in late 2002.

  Purchased Power Agreements

     Great Bay is party to a purchased power agreement, dated as of April 1,
1993 (the "UNITIL Purchased Power Agreement"), with UNITIL Power Corporation
("UNITIL") that provides for Great Bay to sell to UNITIL 0.8696% of the energy
and capacity of Seabrook, approximately 10 MW. The UNITIL Purchased Power
Agreement commenced on May 1, 1993 and runs through October 31, 2010. The
current price of power under the UNITIL Purchased Power Agreement is 5.38 cents
per kilowatt-hour ("kWh"). The price is subject to increase in accordance with a
formula that provides for adjustments at less than the actual rate of inflation.
UNITIL has an option to extend the UNITIL Purchased Power Agreement for an
additional 11 years until 2022.

     The UNITIL Purchased Power Agreement was front-end loaded whereby UNITIL
paid higher prices, on an inflation-adjusted basis, in the early years of the
Agreement and lower prices in later years. The amount of the excess paid by
UNITIL in the early years of the UNITIL Purchased Power Agreement was quantified
in a "Balance Account" which increased annually to a total of $4.1 million in
July 1998, and then decreased annually, reaching zero in July 2001. If the
UNITIL Purchased Power Agreement had terminated prior to its scheduled
termination, and if at that time there was a positive amount in the Balance
Account, Great Bay would have been obligated to refund that amount to UNITIL
Power. To secure the obligation of Great Bay to repay UNITIL the amount in the
Balance Account, the UNITIL Purchased Power Agreement granted UNITIL a "Second
Mortgage" on Great Bay's interest in the Seabrook Project. As the result of the
Balance Account reaching zero in July 2001, the Second Mortgage was discharged
by UNITIL in August 2001.

     To secure the obligation of Great Bay under the UNITIL Purchased Power
Agreement to pay damages in the event of a default by Great Bay, the UNITIL
Purchased Power Agreement grants UNITIL a "Third Mortgage" on Great Bay's
interest in the Seabrook Project. The Third Mortgage is subject and subordinate
to (i) senior mortgages and security agreements securing Great Bay's
indebtedness to lenders in an aggregate amount not to exceed $80,000,000 and
(ii) other mortgages that may be granted by Great Bay to other purchasers of
power from Great Bay to secure a Balance Account or similar obligation. The
UNITIL Purchased Power Agreement further provides that UNITIL's Third Mortgage
will rank pari passu with other mortgages that may be granted by Great Bay to
other purchasers of power from Great Bay to secure potential payment of damages
or similar obligations. The Company is currently evaluating various options
regarding the UNITIL Purchased Power Agreement in order to maximize its value to
the Company.

     Great Bay and Little Bay are parties to a power sales agreement dated as of
November 19, 2001 under which Little Bay sells at cost, and Great Bay purchases,
all of the output of the portion of Seabrook owned by Little Bay. This agreement
is a unit power sale agreement. Accordingly, when all or part of Little Bay's
interest in Seabrook is not producing electricity, the obligation of Little Bay
to sell (and of Great Bay to purchase) is proportionately eliminated. The
agreement can be terminated at any time by mutual consent of the parties, after
any notice required by law.

     In February 2001, Great Bay executed a Purchase Power Agreement with Select
Energy ("Select") whereby Great Bay sold 50 MWs of energy associated with the
Seabrook Project to Select in exchange for 25 MWs of energy associated with
Millstone Unit 2 and 25 MWs of energy associated with Millstone Unit 3.
                                        5
<PAGE>

Millstone is a nuclear power plant located in Connecticut. The term of this
agreement was April 1, 2001 through December 31, 2001. Delivery of power from
either company was contingent on each of the units operating at a certain
capacity.

     As part of the agreement, Select made a prepayment of $3.7 million to Great
Bay in February 2001 and a second prepayment of $3.3 million in March 2001.
Great Bay compensated Select for the prepayments by (i) paying 12% annual
interest for the period from February 6, 2001 through March 31, 2001 and (ii)
giving Select a price differential for the power being exchanged until such time
as the Select prepayment had been repaid. In order to collateralize the
transaction, Great Bay and Little Bay each provided Select with a mortgage lien
and security interest in their respective interests in the Seabrook Project.
Great Bay repaid Select in 2001 and the mortgage liens and security interests
were released as of July 2001. There was no price differential in exchanging
power throughout the remaining term of the agreement.

  Competition

     Great Bay sells its share of Seabrook Project electricity into the
wholesale electricity market in the Northeast United States. There are a large
number of suppliers to this market and a surplus of capacity, resulting in
intense competition. In addition, non-utility wholesale generators of
electricity, such as independent power producers ("IPPs"), Qualifying Facilities
("QFs") and EWGs, as well as power marketers and brokers, actively sell
electricity in this market.

     Great Bay may face increased competition, primarily based on price, from
all the foregoing sources in the future. Great Bay believes that it will be able
to compete effectively in the wholesale electricity market because of the
current low cost of electricity generated by the Seabrook Project in comparison
with existing alternative sources.

  NEPOOL

     Great Bay is a member of the New England Power Pool ("NEPOOL") and is a
party to the Restated NEPOOL Agreement (the "NEPOOL Agreement"). NEPOOL is a
voluntary association of companies engaged in the electricity business in New
England and its membership is open to all investor-owned, municipal and
cooperative electric utilities in New England and other companies that transact
business in the region's bulk power market. Certain end users of electricity may
also become NEPOOL members. The NEPOOL Agreement imposes certain obligations on
its participants concerning generating capacity reserves and the right to use
major transmission lines.

     New England's independent system operator, ISO New England, Inc.
("ISO-NE"), was established in July 1997 and is responsible for maintaining the
safety and reliability of the transmission grid and bulk power market within the
NEPOOL region. ISO-NE performs these functions under a services contract with
NEPOOL. ISO-NE administers a bid-based wholesale market system in New England
that is designed to provide a competitive and efficient generation market
through an hourly clearing price mechanism. During 2001, ISO-NE has been
developing a revised market system, known as Standard Market Design ("SMD"),
which will incorporate location-based pricing and congestion management. The SMD
is currently scheduled to be implemented in December 2002.

  Northeast RTO

     In January 2001, in response to Federal Energy Regulatory Commission
("FERC") Order No. 2000, ISO-NE and six companies owning transmission facilities
in New England filed a joint petition for a declaratory order to form a Regional
Transmission Organization ("RTO") for the NEPOOL control area. The NEPOOL RTO
filing proposed the establishment of two entities working in concert: (1) a new
independent transmission company, Northeast Independent Transmission Company,
LLC ("NE ITC"), and (2) an independent system operator. In July 2001, FERC
issued a series of orders that rejected stand-alone RTO proposals filed by
ISO-NE, the New York ISO ("NYISO"), and the PJM Interconnection ("PJM") and
directed these three northeastern power pools to participate in a mandatory
mediation process with the goal of forming a single Northeast RTO ("NE RTO").
The 45-day NE RTO mediation commenced in July

                                        6
<PAGE>

2001 and ran through early September 2001, and resulted in a business plan for
developing and implementing the NE RTO. However, in early January 2002, PJM
signaled its intent to move away from the NE RTO and instead work to create an
RTO with the Midwest ISO. In late January 2002, ISO-NE and NYISO announced their
intent to continue evaluating the potential of a NE RTO, which may eventually
include Canadian power systems.

  Nuclear Power, Energy and Utility Regulation

     The Seabrook Project and Great Bay and Little Bay, as part owners of a
licensed nuclear facility, are subject to the broad jurisdiction of the NRC,
which is empowered to authorize the siting, construction and operation of
nuclear reactors after consideration of public health and safety, environmental
and antitrust matters. Great Bay and Little Bay have been, and will be, affected
to the extent of their proportionate share by the cost of any such requirements
made applicable to the Seabrook Project.

     Great Bay and Little Bay are also subject to the jurisdiction of the FERC
under Parts II and III of the Federal Power Act and, as a result, are required
to file with FERC all contracts for the sale of electricity. FERC has the
authority to suspend the rates at which Great Bay and Little Bay propose to sell
power, to allow such rates to go into effect subject to refund and to modify a
proposed or existing rate if FERC determines that such rate is not "just and
reasonable." FERC's jurisdiction also includes, among other things, the sale,
lease, merger, consolidation or other disposition of facilities, interconnection
of certain facilities, account and services and property records.

     Because they both are EWG's, Great Bay and Little Bay are not subject to
the jurisdiction of the Securities and Exchange Commission ("SEC") under PUHCA.
In order to maintain their EWG status, Great Bay and Little Bay must continue to
engage exclusively in the business of owning and/or operating all or part of one
or more "eligible facilities" and to sell electricity only at wholesale (i.e.
not to end users) and activities incidental thereto. An "eligible facility" is a
facility used for the generation of electric energy exclusively at wholesale or
used for the generation of electric energy and leased to one or more public
utility companies. The term "facility" may include a portion of a facility. In
the case of Great Bay and Little Bay, their combined 15% joint ownership
interest in the Seabrook Project comprises an "eligible facility."

     Over the past several years, New Hampshire and a number of other New
England states have implemented deregulation of the electric retail utility
industry. In addition, NEPOOL restructured to create and maintain open,
non-discriminatory, competitive, unbundled wholesale markets for energy,
capacity, and ancillary services. The NEPOOL wholesale market commenced
operation in May 1999. All of the deregulation initiatives open retail and
wholesale electricity markets to competition in the affected states. Great Bay
and Little Bay believe they benefit from the deregulation of the electricity
industry, however it is not possible to quantify the impact of deregulation on
the companies. Further, Great Bay and Little Bay remain wholesale sellers of
electricity and have not entered the competitive retail electricity market.

  Nuclear Power Issues

     Nuclear units in the United States have been subject to widespread
criticism and opposition, which has led to construction delays, cost overruns,
licensing delays and other difficulties. Various groups have sought to prohibit
the completion and operation of nuclear units and the disposal of nuclear waste
by litigation, legislation and participation in administrative proceedings. The
Seabrook Project was the subject of significant public controversy during its
construction and licensing and remains controversial. An increase in public
concerns regarding the Seabrook Project or nuclear power in general could
adversely affect the operating license of Seabrook Unit 1. While the Company
cannot predict the ultimate effect of such controversy, it is possible that it
could result in a premature shutdown of the unit.

     In the event of a permanent shutdown of any unit, NRC regulations require
that the unit be completely decontaminated of any residual radioactivity. While
the current owners of the Seabrook Project are accumulating monies in a trust
fund to pay decommissioning costs, if these costs exceed the amount of the trust
fund, the current owners at such time will be liable for the excess.

  Nuclear Related Insurance

     In accordance with the Price Anderson Act, the limit of liability for a
nuclear-related accident is approximately $9.5 billion, effective November 18,
1994. The primary layer of insurance for this liability is $200 million of
coverage provided by the commercial insurance market. The secondary coverage is
approximately $9.3 billion, based on the 106 nuclear units (103 operating units
and three units that still handle used fuel) in the United States. The secondary
layer is based on a retrospective premium assessment of $88.1 million per
nuclear accident per licensed reactor, payable at a rate not exceeding $10
million per year per reactor. In addition, the retrospective premium is subject
to inflation based indexing at five year intervals and, if the sum of all public
liability claims and legal costs arising from any nuclear accident exceeds the
maximum amount of financial protection available, then each licensee can be
assessed an additional 5% ($4.2 million) of the maximum retrospective
assessment. With respect to the Seabrook Project, Great Bay and Little Bay would
be obligated to pay their ownership share of any assessment resulting from a
nuclear incident at any United States nuclear generating facility. Great Bay and
Little Bay estimate their maximum liability per incident currently would be an
aggregate amount of approximately $13.2 million per accident, with a maximum
annual assessment of about $1.5 million per incident, per year.

     The Seabrook Participants are subject to retroactive assessments if losses
under those policies exceed the accumulated funds available to the insurer. The
maximum potential assessments against the Participants with respect to losses
arising during the current policy year for the primary property insurance
program and the excess property damage policies are approximately $8.2 million
and $10.2 million, respectively. The Company's combined 15% share is $1.2
million and $1.5 million, respectively.

     Great Bay and Little Bay also independently purchase business interruption
insurance from Nuclear Electric Insurance Limited ("NEIL"). The current policy
is in effect from April 1, 2001 until April 1, 2002 and a renewal policy has
been signed which will be in effect from April 1, 2002 until April 1, 2003. The
policy provides for the payment of a fixed weekly loss amount of $600,000 in the
event of an outage at the Seabrook Project of more than 23 weeks resulting from
property damage occurring from a "sudden fortuitous event, which happens by
chance, is unexpected and unforeseeable." The maximum amount payable to Great
Bay and Little Bay is a total of $81.1 million. Under the terms of the policy,
Great Bay and Little Bay are subject to a potential retrospective premium
adjustment of up to approximately $789,000 should NEIL's board of directors deem
that additional funds are necessary to preserve the financial integrity of NEIL.
Since NEIL was founded in 1980, there has been no retrospective premium
adjustment; however, there can be no assurance that NEIL will not make
retrospective adjustments in the future. The liability for this retrospective
premium adjustment ceases six years after the end of the policy unless prior
demand has been made.

     The board and management of NEIL has announced, that in light of the events
of September 11, 2001, the current coverage for terrorism will remain available
under all the NEIL policies, but with the addition of a provision regarding the
maximum recoveries available for multiple terrorism occurrences. The NEIL board
approved the following changes to the NEIL policy forms to respond to the
increased potential of multiple terrorism losses at insured sites: (1) increase
the multiple for the maximum retrospective premium adjustments from five to ten;
and (2) provide specifically for the use of NEIL resources for multiple losses
resulting from terrorism within one year. Under this provision, all losses
occurring within 12 months from the date of the first loss would share a single
recovery of $3.24 billion plus any amounts NEIL recovers from reinsurers or the
government, with priority for the property claims over accidental outage claims.

  Nuclear Fuel

     NAESCO, the Seabrook Project's managing agent, has made, or expects to
make, various arrangements for the acquisition of uranium concentrate, the
conversion, enrichment, fabrication and utilization of nuclear fuel and the
disposition of that fuel after use. Many of these arrangements are pursuant to
multi-year contracts with concentrate and service providers. Based on the
Seabrook Project's existing contractual arrangements, Great Bay and Little Bay
believe that the Seabrook Project has available, or under supply contracts,
sufficient nuclear fuel for operations through approximately 2004. Uranium
concentrate and conversion, enrichment and

                                        8
<PAGE>

fabrication services currently are available from a variety of sources. The cost
of such concentrate and such services varies based upon market forces.

  Nuclear Waste Disposal

     Costs associated with nuclear plant operations include amounts for nuclear
waste disposal, including spent fuel, as well as for the ultimate
decommissioning of the plants. The Nuclear Waste Policy Act of 1982 (the "NWPA")
requires the United States Department of Energy (the "DOE"), subject to various
contingencies, to design, license, construct and operate a permanent repository
for high level radioactive waste and spent nuclear fuel, which are collectively
referred to as "high-level waste."

     The joint owners of the Seabrook Project, through their managing agent
NAESCO, entered into contracts with the DOE for high-level waste disposal in
accordance with the NWPA. Under these contracts and the NWPA, the DOE was
required to take title to and dispose of the Seabrook Project's high-level waste
beginning no later than January 31, 1998. The DOE has not met its contractual
and statutory requirements under the NWPA calling for the DOE to begin accepting
spent fuel from the industry by January 1998. The DOE announced that its first
high-level waste repository will not be in operation until 2010 at the earliest.

     As a result of this delay, many states and nuclear plant operators,
including NAESCO, sued the DOE for injunctive relief and monetary damages. Two
U.S. Courts of Appeals ordered the DOE to proceed with its high-level waste
disposal obligations and ruled that plant operators are entitled to monetary
damages from DOE. However, there can be no assurance that the Seabrook Project
will collect damages from the DOE because, among other things, NAESCO's case
against the DOE is still pending. Until the DOE begins receiving nuclear waste
materials in accordance with the NWPA and its contracts, nuclear plants such as
Seabrook must retain high-level waste on-site or make other storage provisions.
In addition, NAESCO has advised the Company that the Seabrook Project has
adequate on-site storage capacity for high-level waste until approximately 2008.

     In May 2001, the DOE issued a supplement to the 1999 draft Environmental
Impact Statement of Yucca Mountain in Nevada, and public hearings on this
document were held in mid-2001. On February 14, 2002, the DOE recommended to
President Bush that Yucca Mountain in Nevada be developed as the nation's first
long-term geologic repository for the disposal of spent nuclear fuel high-level
nuclear waste. On February 15, 2002 the President notified Congress that he
considers Yucca Mountain qualified for a construction permit application, taking
the next in a series of steps required for approving the site as a nuclear
materials repository.

     The Low-Level Radioactive Waste Policy Act of 1980 requires each state to
provide disposal facilities for low-level waste ("LLW") generated within the
state, either by constructing and operating facilities or by joining regional
compacts with other states to jointly fulfill their responsibilities. However,
the Low-Level Radioactive Waste Policy Amendments Act of 1985 permits each state
in which a currently operating disposal facility is located (South Carolina,
Nevada and Washington) to impose volume limits and a surcharge on shipments of
LLW from states that are not members of their regional compact.

     The Seabrook Project ships certain LLW to privately owned facilities in
South Carolina and Utah. Since 1999, the Project has been shipping LLW to a
processing facility in Tennessee where the material is subjected to separation
and volume reduction methods to minimize the final volume to be disposed at a
burial site. All LLW generated by the Seabrook Project that exceeds the maximum
radioactivity level of LLW accepted by these facilities is currently stored
on-site at the Seabrook facility. LLW from normal Seabrook Project operations
will continue to be generated at a slow rate as a result of aggressive efforts
at the Seabrook Project to minimize this material. NAESCO has advised the
Company that the Seabrook Project's capacity for on-site storage of LLW is
expected to be sufficient to meet the project's storage requirements through
2006.

  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

                                        9
<PAGE>

concerning decommissioning planning, timing, funding and environmental review.
Changes in NRC requirements or technology can increase estimated decommissioning
costs.

     Great Bay and Little Bay are responsible for their pro rata share of the
decommissioning and cancellation costs for Seabrook. Great Bay pays its share of
decommissioning funding on a monthly basis. Little Bay's share of
decommissioning costs was prefunded by Montaup, the owner of the 2.9% interest
in the Seabrook Project that Little Bay acquired in November 1999. As part of
that acquisition, Montaup transferred approximately $12.4 million into Little
Bay's decommissioning account, an irrevocable trust earmarked for Little Bay's
share of Seabrook Plant decommissioning expenses.

     The Seabrook decommissioning funding schedule is determined by the New
Hampshire Nuclear Decommissioning Financing Committee (the "NDFC"). The NDFC
reviews the decommissioning funding schedule for the Seabrook Project at least
annually and, for good cause, may increase or decrease the amount of the funds
or alter the funding schedule.

     On November 5, 2001, the NDFC issued a Final Report and Order in proceeding
NDFC Docket 2001-1, which established a decommissioning funding schedule in
anticipation of the sale of a majority of the ownership interests in Seabrook.
The NDFC set an accelerated funding schedule for the years 2002 through 2006.
For the years 2007 and beyond, the funding schedule assumes contributions will
be made until 2026. The order also established the requirement for a lump sum
"top-off" payment at closing. The current estimated cost to decommission the
Seabrook Project (based on NDFC Docket 2001-1), is approximately $555.6 million
in 2001 dollars, assuming for decommissioning funding purposes, a remaining
24-year life for the facility and a future cost escalation of 5.25%.

     Funds collected by Seabrook for decommissioning are deposited in an
external irrevocable trust pending their ultimate use. The earnings on the
external trusts also accumulate in the fund balance. The trust funds are
restricted for use in paying for the decommissioning of Unit 1. The investments
in the trust are available for sale. Great Bay and Little Bay have therefore
reported their investment in trust fund assets at market value and any
unrealized gains and losses are reflected in equity. There was an unrealized
holding gain of approximately $221,700 as of December 31, 2001.

     Although the owners of the Seabrook Project are accumulating funds in an
external trust to defray decommissioning costs, these costs could substantially
exceed the value of the trust fund, and the owners, including Great Bay and
Little Bay, would remain liable for the excess.

     In June 1998, the New Hampshire State legislature enacted legislation that
provides that in the event of a default by Great Bay on its payments to the
decommissioning fund, the other Seabrook joint owners would be obligated to pay
their proportional share of such default. As a result of the enactment of this
legislation, the NRC staff found that Great Bay complied with the
decommissioning funding assurance requirements. In July 1998, the staff of the
NRC notified Great Bay of the staff's determination that Great Bay complied with
the decommissioning funding assurance requirements under NRC regulations.

     In response to the New Hampshire legislation, Great Bay agreed to make
accelerated payments to the Seabrook decommissioning fund such that Great Bay
will have contributed sufficient funds by the year 2015 to allow sufficient
monies to accumulate, with no further payments by Great Bay to the fund, to the
full estimated amount of Great Bay's decommissioning obligation by the time the
current Seabrook operating license expires in 2026. Based on the currently
approved funding schedule and Great Bay's accelerated funding schedule, Great
Bay's decommissioning payments will be approximately $1.4 million in 2002 and
escalate at 4% each year thereafter through 2015.

     On November 15, 1992, Great Bay's former parent, EUA, and certain other
parties entered into a settlement agreement. Under the settlement agreement, EUA
guaranteed an amount not to exceed $10 million of Great Bay's future
decommissioning costs of Seabrook Unit 1 in the event that Great Bay is unable
to pay its share of such decommissioning costs.

  Environmental Regulation

     The Seabrook Project, like other electric generating stations, is subject
to standards administered by federal, state and local authorities with respect
to the siting of facilities and associated environmental factors. The United
States Environmental Protection Agency (the "EPA"), and certain state and local
authorities, have jurisdiction over releases of pollutants, contaminants and
hazardous substances into the environment and have broad authority in connection
therewith, including the ability to require installation of pollution control
devices and remedial actions. The NRC has promulgated a variety of standards to
protect the public from radiological pollution caused by the normal operation of
nuclear generating facilities.

     The EPA issued a National Pollutant Discharge Elimination System ("NPDES")
permit, valid for a period of five years, to NAESCO on October 30, 1993
authorizing discharges from Seabrook Station into the Atlantic Ocean and the
Browns River in accordance with limitations, monitoring requirements and
conditions specified in the permit. A renewal application was filed in April
1998 and supplemented in August and September of 1998 and in September 1999. The
EPA issued a draft NPDES permit in December 2001. The final permit was issued in
February 2002. The permit indicates that the Seabrook Project water cooling
system represents the best technology available.

     On July 26, 1999, the New Hampshire Department of Environmental Services
issued a renewal of NAESCO permits to operate two auxiliary boilers, two
emergency diesel generators and other smaller units in accordance with New
Hampshire Revised Statutes Annotated Chapter 125-C. These permits prescribe
limits of the emission of air pollutants into the ambient air as well as record
keeping and other reporting criteria. Because the liabilities of the
Participants under the JOA are several and not joint, in the event that NAESCO
violates the emissions limits contained in its permits, if at all, Great Bay and
Little Bay will be liable for their pro rata share of any costs and liabilities
assessed for the emissions violations.

     In some environmental areas, the NRC and the EPA have overlapping
jurisdiction. Thus, in addition to being subject to NRC regulations, the
Seabrook Project is subject to all conditions imposed by the EPA and a variety
of federal environmental statutes, including obtaining permits for the discharge
of pollutants (including heat, which is discharged by the Seabrook Project) into
the nation's navigable waters. In addition, the EPA has established standards,
and is in the process of reviewing existing standards, for certain toxic air
pollutants, including radionuclides, under the United States Clean Air Act which
apply to NRC-licensed facilities. The effective date for the new EPA
radionuclide standard has been stayed as applied to nuclear generating units.
Environmental regulation of the Seabrook Project may result in material
increases in capital and operating costs, delays or cancellation of construction
of planned improvements, or modification or termination of operation of existing
facilities. Management believes that Great Bay and Little Bay are in compliance
in all material respects with applicable EPA, NRC and other regulations relating
to pollution caused by nuclear generating facilities.

  Equity Investment in HoustonStreet

     BayCorp owns a 45.9% equity interest in HoustonStreet. HoustonStreet
developed and operates HoustonStreet.com, an Internet-based, independent crude
oil and refined products trading exchange in the United States.

     HoustonStreet's crude oil platform includes several trading floors,
organized by grade and location. The platform allows for a user-customized view
where the user can specify which markets should appear together on a floor,
regardless of grade, location or type. HoustonStreet's refined products platform
includes several trading floors, organized by commodity, pipeline and geographic
location. Bids and offers are segmented by trading period (month and cycle) and
by grade. Commodities traded include numerous grades of gasoline and
distillates, specifically jet fuel, number 2 heating oil, low sulfur diesel,
regular gas, regular reformulated gas, premium gas and premium reformulated gas.

     On March 30, 2001, HoustonStreet raised approximately $2.9 million in
additional funding, including $450,000 from BayCorp, by selling senior secured
notes, warrants to purchase HoustonStreet preferred stock and warrants to
purchase HoustonStreet common stock. Collectively, these securities are referred
to as the

                                        11
<PAGE>

"HoustonStreet Series C Units." In April 2001, BayCorp authorized HoustonStreet
to convert BayCorp's $7 million loan made in 2000, along with approximately $1
million in accrued interest and penalties on the note and past due management
fees, into $8 million of Series C Units. The loan, accrued interest and
receivables from HoustonStreet had been written down to zero as of December 31,
2000 and as such, the conversion of these amounts had no accounting impact on
BayCorp.

     In 2001, HoustonStreet downsized its organization and shut down its
electricity trading platforms, shifting it business focus to its crude oil and
refined products trading platforms. In addition, HoustonStreet intends to
leverage its open architecture in order to integrate trade information with its
customers' mid- and back-office applications.

EMPLOYEES AND MANAGEMENT

     As of March 15, 2002, BayCorp had 11 employees. Its subsidiaries, Great Bay
and Little Bay, had no employees. As of March 15, 2002, HoustonStreet had six
employees.

     BayCorp entered into Management and Administrative Services Agreements (the
"Services Agreements") with Great Bay and HoustonStreet. Under the Services
Agreement with Great Bay, BayCorp provides Great Bay with a full range of
management services, including general management and administration, accounting
and bookkeeping, budgeting and regulatory compliance. Great Bay paid $1,203,600
to BayCorp for these services in 2001. Under the Services Agreement with
HoustonStreet, BayCorp provides HoustonStreet with administrative, accounting
and bookkeeping, budgeting and human resource services. HoustonStreet paid
$165,000 to BayCorp in 2001 for these services. Each Services Agreement has a
one-year term and provides for automatic one-year renewals.

ITEM 2.  PROPERTIES.

     BayCorp's principal assets include its 100% equity interests in Great Bay
and Little Bay. In turn, Great Bay and Little Bay's principal asset is a
combined 15% joint ownership interest in the Seabrook Project. The Seabrook
Project is a nuclear-fueled, steam electricity, generating plant located in
Seabrook, New Hampshire, which was planned to have two Westinghouse pressurized
water reactors, Seabrook Unit 1 and Seabrook Unit 2 (each with a rated capacity
of 1,150 megawatts), utilizing ocean water for condenser coiling purposes.
Seabrook Unit 1 entered commercial service on August 19, 1990. Seabrook Unit 2
has been canceled. See "Business -- The Seabrook Project." BayCorp has a 45.9%
equity interest in HoustonStreet.

     BayCorp's corporate headquarters is located in Eliot, Maine where it
occupies approximately 5,000 square feet of office space. BayCorp's management
believes that the corporate headquarters in Eliot, Maine meets its current
requirements and that additional space can be obtained to meet requirements for
the foreseeable future.

     As of March 14, 2002, the Company had 28 holders of record of its Common
Stock. The Company believes that as of March 14, 2002, the Company had
approximately 979 beneficial holders of its Common Stock. The number of
beneficial owners substantially exceeds the number of record holders because
many of the Company's stockholders hold their shares in street name.

     BayCorp has never paid cash dividends on its common stock. Any future
dividends depend on future earnings, BayCorp's financial condition and other
factors.

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

OVERVIEW

     BayCorp derives all of its revenue through its energy trading activities
and its 100% equity interest in Great Bay and Little Bay. Great Bay and Little
Bay are electricity generating companies whose principal asset is a combined 15%
joint ownership interest in the Seabrook Nuclear Power Project in Seabrook, New
Hampshire.

     BayCorp reported net income for the year ended December 31, 2001 and
reported net losses for the years ended December 31, 2000, 1999, 1998 and 1997.
The net income in 2001 was primarily attributable to increased revenues and the
realized gain in 2001 on firm forward energy trading contracts. The 2000 net
loss was primarily attributable to the non-cash charge to earnings for
unrealized losses on firm forward trading contracts and the costs associated
with a Seabrook refueling outage during the final ten weeks of 2000. The 1999
net loss was primarily due to costs associated with the refueling outage during
the fall of 1999. The 1998 net loss was primarily due to the costs associated
with the unscheduled outages at the Seabrook Project that occurred during the
year and to the charge related to the termination of a power marketing agreement
between Great Bay and PECO Energy Company. The 1997 net loss was primarily due
to costs associated with the scheduled and unscheduled outages at the Seabrook
Project that occurred during that year.

     The Seabrook Project from time to time experiences both scheduled and
unscheduled outages. BayCorp incurs losses during outage periods due to the loss
of all revenues from the sale of generation and additional costs associated with
the outages as well as continuing operating and maintenance expenses and
depreciation. Unscheduled outages or operation of the unit at reduced capacity
can occur due to the automatic operation of safety systems following the
detection of a malfunction. In addition, it is possible for the unit to be shut
down or operated at reduced capacity based on the results of scheduled and
unscheduled inspections and routine surveillance by Seabrook Project personnel.
It is not possible for BayCorp to predict the frequency or duration

                                        14
<PAGE>

of any future unscheduled outages; however, it is likely that such unscheduled
outages will occur. Refueling outages are generally scheduled every 18 months
depending upon the Seabrook Project capacity factor and the rate at which the
nuclear fuel is consumed. There was no refueling outage in 2001. The Seabrook
Project conducted a refueling outage in 2000, which began on October 21, 2000.
This refueling outage was scheduled for approximately 30 days, however due to
unexpected mechanical problems, the Seabrook Project did not return to full
power until February 1, 2001. The next refueling outage is scheduled to begin in
May 2002.

     The following discussion focuses solely on operating revenues and operating
expenses that are presented in a substantially consistent manner for all of the
periods presented.

RESULTS OF OPERATIONS

  Operating Revenues

     BayCorp's operating revenues for 2001 increased by approximately
$23,100,000, or 41.1%, to $79,480,000 as compared to $56,347,000 for 2000. The
increase was attributable to several factors. The capacity factor at the
Seabrook Project was 85.8% of the rated capacity for the twelve months ended
December 31, 2001 as compared to a capacity factor of 85.2% for the twelve
months ended December 31, 2000. Operating revenues and capacity factor were
adversely impacted in 2000 and 2001 by the scheduled refueling outage at the
Seabrook Project that began on October 21, 2000. A return to full power was
expected on November 21, 2000. The outage was extended when damage to one of the
plant's emergency diesel generators occurred, requiring an extensive repair
effort. The Seabrook Project returned to full power on February 1, 2001. The
Company purchased a significant amount of power to cover firm contracts,
primarily due to this refueling outage, and also purchased power for resale in
2001, thus increasing revenues. Purchased power expenses for the twelve months
ended December 31, 2001 were approximately $27,008,000 as compared to
approximately $13,270,000 for the twelve months ended December 31, 2000
primarily due to increased power purchases. Increases in capacity factor and
purchased power increased sales of electricity by approximately 27.6% to
1,854,967,500 kWhs in 2001 as compared to 1,453,263,900 kWhs in 2000.

     The Company also realized a higher average selling price in 2001. During
the twelve months ended December 31, 2001, the average selling price increased
10.9% to 4.29 cents per kWh as compared to an average selling price of 3.87
cents per kWh for the twelve months ended December 31, 2000.

     Great Bay's cost of power (determined by dividing total operating expenses
by kWhs sold during the applicable period) decreased 35% to 3.02 cents per kWh
in 2001 as compared to 4.61 cents per kWh in 2000. This decrease was primarily
the result of increased kWhs sold in 2001 and lower operating expenses due to
realized gains on firm forward contracts of approximately $12,879,000 in 2001 as
compared to higher operating expenses in 2000 due to unrealized losses on firm
forward contracts of approximately $12,232,000 in 2000.

     BayCorp's operating revenues for 2000 increased by approximately
$10,600,000, or 23.2%, to $56,347,000 as compared to $45,731,000 for 1999. This
increase was primarily attributable to increases in selling prices in 2000 as
compared to 1999. During 2000, the sales price kWh increased 23% to 3.87 cents
per kWh as compared with 3.13 cents per kWh in 1999. Sales of electricity
decreased slightly by approximately 0.2% to 1,453,263,900 kWhs in 2000 as
compared to 1,457,110,270 kWhs in 1999. The 2000 capacity factor at the Seabrook
Project was 85.2% of the rated capacity as compared to a capacity factor of
85.6% for 1999. Operating revenues and capacity factor were adversely impacted
in 2000 by the scheduled refueling outage at the Seabrook Project that began on
October 21, 2000 as mentioned above. Operating revenues and capacity factor were
adversely impacted in 1999 by the scheduled refueling outage that began on March
27, 1999. Great Bay purchased approximately 262,409,300 kWhs for resale in 2000
primarily to cover firm contracts during the extended outage in the fourth
quarter.

     Great Bay's cost of power increased 38% to 4.61 cents per kWh in 2000 as
compared to 3.33 cents per kWh in 1999. This increase was primarily the result
of the expense associated with the unrealized losses on firm forward contracts
of approximately $12.2 million in 2000 as compared to $806,000 in 1999.

                                        15

  Expenses

     BayCorp's total operating expenses for 2001 decreased approximately
$11,039,000, or 16.5%, in comparison with 2000. This decrease was primarily the
result of the non-cash charge to earnings for unrealized gains/losses on firm
energy trading contracts. In 2001, the Company realized gains on firm forward
energy trading contracts of $12,879,000 and total operating expenses were
reduced by this amount. In 2000, total operating expenses were higher because
the Company recorded unrealized losses on firm forward energy trading contracts
of $12,232,000. As of December 31, 2000, the company held numerous firm forward
energy trading contracts to deliver power in 2001. The Company had no firm
forward energy trading contracts as of December 31, 2001, nor does it expect to
in 2002, in light of its expected sale of its ownership interest in the Seabrook
Project in late 2002.

     Production and transmission costs decreased approximately $655,000, or
2.5%, from $26,089,000 in 2000 to $25,434,000 in 2001. Purchased power expenses
increased approximately $13,738,000, or 103%, from $13,270,000 in 2000 to
$27,008,000 in 2001. This increase was primarily attributable to the extended
duration of the 2000 refueling outage that began on October 21, 2000. A return
to full power was expected on November 21, 2000. The outage was extended when
damage to one of the plant's emergency diesel generators occurred, requiring an
extensive repair effort. The Seabrook Project returned to full power on February
1, 2001. In order to cover some of its firm energy contracts and to secure cash
to cover some of its operating costs in the first half of 2001, Great Bay
executed a Purchase Power Agreement with Select in February 2001 whereby Great
Bay sold 50 MWs of energy associated with Seabrook to Select in exchange for 25
MWs of energy associated with Millstone Unit 2 and 25 MWs of energy associated
with Millstone Unit 3. The term of this agreement was April 1, 2001 through
December 31, 2001. See "Business -- Purchased Power Agreements."

     Administrative and general expenses increased approximately $1,839,000, or
25%, from $7,372,000 in 2000 to $9,211,000 in 2001. This increase was primarily
attributable to costs associated with employee turnover and retirements at the
Seabrook Project in 2001 and a bad debt expense of $1,100,000 to establish a
reserve for bad debts specific to Enron. See "Recent Developments." There was no
similar charge in 2000.

     Depreciation and amortization charges decreased approximately $429,000, or
10.3%, from $4,159,000 in 2000 to $3,730,000 in 2001. This decrease was
primarily due to a reduction in fixed asset values. Taxes other than income
decreased $422,000, or 10.7%, from $3,938,000 in 2000 to $3,516,000 in 2001.
This decrease was due to the continued reduction in Seabrook property taxes
resulting from prior year negotiations between the management of the Seabrook
Project and the towns of Seabrook, Hampton and Hampton Falls, New Hampshire to
reduce the assessed value of the Seabrook Project.

     Interest and dividend income decreased approximately $642,000, or 55.2%,
from $1,162,000 in 2000 to $520,000 in 2001, primarily due to lower average
monthly cash balances and lower interest rates in 2001 as compared 2000.
Although the Company's cash balance at December 31, 2001 of $17,181,000 was
approximately 55% greater than its cash balance at December 31, 2000, the
Company's cash balance during the first half of 2001 was adversely affected by
the late 2000 and early 2001 outage and was favorably affected by strong
operations at Seabrook during the second half of 2001.

     Decommissioning cost accretion decreased $372,000, or 10.2%, to $3,261,000
in 2001 as compared to $3,633,000 in 2000. This accretion is a non-cash charge
that reflects Great Bay's liability related to the closure and decommissioning
of the Seabrook Project in current year dollars over the licensing period during
which the Seabrook Project is licensed to operate. Decommissioning trust fund
income decreased $127,000, or 7.4%, to $1,599,000 in 2001 as compared to
$1,726,000 in 2000. The decrease in interest earned on the decommissioning trust
fund reflected the lower rates of returns on investments.

     Equity loss in BayCorp's HoustonStreet investment was $4,352,000 in 2000 as
compared to $450,000 in 2001. As of December 31, 1999, the Company owned 100% of
HoustonStreet. The Company recognized its ownership share of HoustonStreet's
losses, $3,396,000, for 1999. HoustonStreet raised additional equity in 2000
from outside investors and as a result, as of December 4, 2000, the Company's
ownership fell below 50%, to 45.9%. Subsequently, the Company deconsolidated
HoustonStreet as of December 4, 2000 and started

                                        16
<PAGE>

accounting for this investment on the equity method. The net financial impact of
this deconsolidation was $4,352,000, recorded in 2000. BayCorp invested $450,000
in HoustonStreet in 2001 and recorded as an equity loss in investment.

     Other income (deductions) decreased approximately $932,000, to a net
deduction in 2001 of $179,000 as compared to other income in 2000 of $753,000.
This decrease in other income is primarily due to lower administrative fees
charged to HoustonStreet in 2001 as compared to 2000 and fewer sales of
miscellaneous Unit 2 equipment at Seabrook in 2001 as compared to 2000.

     BayCorp's total operating expenses for 2000 increased $21.4 million, or
47%, in comparison with 1999. This increase was primarily the result of the
non-cash charge to earnings for unrealized losses on firm energy trading
contracts. Unrealized losses for firm energy trading contracts were $12,232,000
for 2000 as compared to $806,000 for 1999. Production costs increased
approximately $6,800,000, or 37.3%, from $18,220,000 in 1999 to $25,016,000 in
2000. This increase was primarily the result of the Company's increased
ownership in the Seabrook Project, from approximately 12.1% for the first eleven
months of 1999 to approximately 15% for December 1999 and all of 2000. In
addition, the increase in operating expenses in 2000 as compared to 1999 was
attributable to the costs associated with the extended refueling outage in the
fourth quarter of 2000. Purchased power expenses increased approximately
$1,000,000, or 8.5%, from $12,232,000 in 1999 to $13,270,000 in 2000. This
increase was primarily attributable to an increase in the purchase price of
power in 2000 as compared to 1999.

     Administrative and general expenses increased approximately $666,000, or
9.9%, from $6,706,000 in 1999 to $7,372,000 in 2000. Depreciation and
amortization increased approximately $336,000, or 8.8%, from $3,823,000 in 1999
to $4,159,000 in 2000. These increases were primarily attributable to the
increased ownership in the Seabrook Project in 2000 as compared to 1999. Taxes
other than income increased approximately $972,000, or 32.8%, from $2,966,000 in
1999 to $3,938,000 in 2000. In addition to expenses increasing as a result of
the Company's increased ownership in the Seabrook Project, Great Bay also
received a property tax refund in 1999 as settlement for changes in assessed
property values.

     Interest and dividend income increased approximately $514,000, or 79.3%,
from $648,000 in 1999 to $1,162,000 in 2000, primarily due to higher average
cash balances during 2000 as compared to 1999. Decommissioning cost accretion
increased $313,000, or 9.4%, to $3,633,000 in 2000 as compared to $3,320,000 in
1999. Decommissioning trust fund income increased $971,000, or 128%, to
$1,726,000 in 2000 as compared to $755,000 in 1999. The increase in interest
earned on the decommissioning trust fund reflected the higher 2000 fund balances
as Great Bay continued to make contributions to the Great Bay decommissioning
trust fund and the addition of the Little Bay decommissioning trust funds in
2000. Other Income increased approximately $443,000, or 143%, to $753,000 in
2000 as compared to $310,000 in 1999, primarily due to miscellaneous sales of
Unit 2 equipment at Seabrook.

     Equity loss in HoustonStreet investment was $4,352,000 in 2000 and
$3,396,000 in 1999. As of December 31, 1999, the Company owned 100% of
HoustonStreet. The Company recognized its ownership share of HoustonStreet's
losses, $3,396,000, for 1999. HoustonStreet raised additional equity in 2000
from outside investors and as a result, as of December 4, 2000, the Company's
ownership fell below 50%, to 45.9%. Subsequently, the Company deconsolidated
HoustonStreet as of December 4, 2000 and started accounting for this investment
on the equity method. The net financial impact of this deconsolidation was
$4,352,000, recorded in 2000.

  Net Operating Losses

     For federal income tax purposes, as of December 31, 2001, the Company had
net operating loss carry forwards ("NOLs") of approximately $208 million, which
are scheduled to expire between 2004 and 2019. Because the Company has
experienced one or more ownership changes, within the meaning of Section 382 of
the Internal Revenue Code of 1986, as amended, an annual limitation is imposed
on the ability of the Company to use $115 million of these carryforwards. The
Company's best estimate at this time is that the annual limitation on the use of
$115 million of the Company's NOLs is approximately $5.5 million per year. Any
unused portion of the $5.5 million annual limitation applicable to the Company's
restricted NOL's is

                                        17
<PAGE>

available for use in future years until such NOL's are scheduled to expire. The
Company's other $93 million of NOLs are not currently subject to such
limitations.

LIQUIDITY AND CAPITAL RESOURCES

     BayCorp's subsidiary, Great Bay, currently sells most of its power in the
Northeast United States short-term wholesale power market. The cash generated
from electricity sales by Great Bay was sufficient to meet the Company's ongoing
cash requirements in 2001. If the Seabrook Project operates at a capacity factor
below historical levels, or if expenses associated with the ownership or
operation of the Seabrook Project, including without limitation decommissioning
costs, are materially higher than anticipated, or if the prices at which Great
Bay is able to sell its share of the Seabrook Project electricity decrease from
current price levels, BayCorp or Great Bay would be required to raise additional
capital, either through a debt financing or an equity financing, to meet ongoing
cash requirements. Nonetheless, there can be no assurance that BayCorp or Great
Bay will be able to raise additional capital on acceptable terms or at all.

     On January 4, 2002, BayCorp reported that Great Bay received notice on
December 21, 2001 from Enron that Enron was terminating it contracts with Great
Bay. Enron owes Great Bay $1,075,200 for power delivered prior to Enron's
Chapter 11 bankruptcy filing on December 2, 2001. Great Bay also had an
administrative claim against Enron of $684,100 for power delivered between
December 2, 2001 and December 21, 2001 and an unliquidated claim for damages
resulting from the termination of the contracts. Enron paid $684,100 to Great
Bay on February 21, 2002. During the fourth quarter of 2001, BayCorp recorded an
expense of $1,100,000 to establish a reserve for doubtful accounts due to the
uncertainty of collecting remaining amounts owed by Enron to Great Bay for power
delivered prior to Enron's Chapter 11 bankruptcy filing.

     On February 6, 2001, Great Bay executed a Purchase Power Agreement with
Select whereby Great Bay sold 50 MWs of energy associated with Seabrook to
Select in exchange for 25 MWs of energy associated with Millstone Unit 2 and 25
MWs of energy associated with Millstone Unit 3. The term of this agreement was
April 1, 2001 through December 31, 2001. Delivery of power from either company
was contingent on each of the units operating at certain capacity.

     As part of the agreement, Select made a prepayment of $3.7 million to Great
Bay in February 2001 and a second prepayment of $3.3 million in March 2001.
Great Bay compensated Select for the prepayments by (i) paying 12% annual
interest for the period from February 6, 2001 through March 31, 2001 and (ii)
giving Select a price differential for the power being exchanged until such time
as the Select prepayment has been repaid. In order to collateralize the
transaction, Great Bay and Little Bay each provided Select with a mortgage lien
and security interest in their respective interests in the Seabrook Project.
Great Bay repaid Select in 2001 and the mortgage liens and security interests
were released as of July 2001. There was no price differential in exchanging
power throughout the remaining term of the agreement.

     The Company's principal asset available to serve as collateral for
borrowings is Great Bay's and Little Bay's combined 15% interest in the Seabrook
Project. Pursuant to a purchased power agreement, dated as of April 1, 1993,
between Great Bay and UNITIL, Great Bay's interest in the Seabrook Project is
encumbered by a mortgage. This mortgage is subject and subordinate to up to $80
million of senior secured financing and certain other mortgages.

     BayCorp's total cash and short-term investments increased approximately
$3,100,000 during 2001. The principal factor affecting liquidity during 2001 was
the Company's net income of $21,688,000 reduced by the non-cash credit to
income, realized gain on forward firm energy trading contracts, of approximately
$12,879,000. Other non-cash charges to income included $3,272,000 for
depreciation and amortization, $4,140,000 for nuclear fuel amortization and
$3,261,000 for decommissioning cost accretion. In addition, there was an
increase in miscellaneous liabilities of approximately $4,216,000 primarily due
to the monthly accrual for outage costs estimated for the May 2002 refueling
outage. Offsetting these non-cash charges to income were cash charges including
approximately $1,284,000 for decommissioning interest. There was an approximate
$3,160,000 increase in accounts receivable. This increase was primarily due to
higher sales in December 2001 as compared to December 2000 when there was a
refueling outage at the Seabrook Project. In addition, there was an approximate
$6,580,000 decrease in accounts payable primarily due to higher accounts payable

                                        18
<PAGE>

for purchased power in December 2000 as compared to December 2001. Other cash
charges included approximately $1,788,000 for capital expenditures and
$5,017,000 for nuclear fuel.

     Great Bay's 2001 decommissioning payments totaled approximately $2,617,000.
The decommissioning funding schedule is determined by the NDFC, which reviews
the schedule for the Seabrook Project at least annually. Great Bay expects to
use revenues from the sale of power to make decommissioning payments. See
"Business -- Decommissioning."

     BayCorp received approximately $423,000 in 2001 from the exercise of
options to purchase 67,000 shares of BayCorp common stock by former employees of
the Company. Also in 2001, BayCorp invested $450,000 in cash in HoustonStreet.
This amount was recorded as an equity loss in HoustonStreet for 2001 and net
income for 2001 was reduced by $450,000.

     Great Bay anticipates that its share of the Seabrook Project's capital
expenditures for the 2002 fiscal year will total approximately $5.3 million for
nuclear fuel and various capital projects. In addition, Great Bay is required
under the JOA to pay its share of Seabrook Unit 1 and Seabrook Unit 2 expenses,
including, without limitation, operation and maintenance expenses, construction
and nuclear fuel expenditures and decommissioning costs, regardless of the level
of Seabrook Unit 1's operations.

     In October 2000, the Company announced that it reached an agreement with
Northeast Utilities ("NU") under which the Company's generating subsidiaries,
Great Bay and Little Bay, will include their aggregate 15% ownership share of
the Seabrook Project in the current auction of NU's subsidiaries' shares of the
Seabrook Project. Under the terms of the agreement, BayCorp will receive the
sales price established by the auction process. In the event that the sale
yields proceeds for BayCorp of more than $87.2 million, BayCorp and NU will
share the excess proceeds. Should BayCorp's sales proceeds be less than $87.2
million, NU will make up the difference below that amount on a dollar for dollar
basis up to a maximum of $17.4 million. Under the agreement, BayCorp will be
paid separately for nuclear fuel and inventory. The agreement also limits any
top-off amount required to be funded by BayCorp for decommissioning as part of
the sale process at the amount required by the Nuclear Regulatory Commission
("NRC") regulations. The auction began in the last quarter of 2001 with a
closing expected in the last quarter of 2002.

CERTAIN FACTORS THAT MAY AFFECT FUTURE RESULTS

     This Annual Report contains forward-looking statements. For this purpose,
any statements contained in this report that are not statements of historical
fact may be deemed to be forward-looking statements. Without limiting the
foregoing, the words "believes," "anticipates," "plans," "expects," "intends"
and similar expressions are intended to identify forward-looking statements.
There are a number of important factors that could cause the results of BayCorp
and/or its subsidiaries to differ materially from those indicated by such
forward-looking statements. These factors include, without limitation, those set
forth below and elsewhere in this report.

     History of Losses.  BayCorp reported operating income for 2001. Prior to
2001, BayCorp had never reported an operating profit for any year since its
incorporation. Until 2001, electricity sales at short-term rates have not
resulted in sufficient revenue to enable BayCorp to meet its cash requirements
for operations, maintenance and capital related costs. In addition, and despite
recently increasing prices for electricity in the northeast United States, there
can be no assurance that Great Bay or Little Bay will be able to sell power at
prices that will enable them to meet their cash requirements.

     Liquidity Need.  As of December 31, 2001, BayCorp had approximately
$17,100,000 in cash and cash equivalents, restricted cash and short-term
investments. The Company believes that such cash, together with the anticipated
proceeds from the sale of electricity by Great Bay and Little Bay, will be
sufficient to enable the Company and its wholly owned subsidiaries to meet their
cash requirements in 2002. However, if in 2002, the Seabrook Project operates at
a capacity factor below historical levels, or if expenses associated with the
ownership or operation of the Seabrook Project, including without limitation
decommissioning costs, costs associated with the May 2002 scheduled refueling
outage and costs associated with the sale of the Seabrook Project, are
materially higher than anticipated, or if the prices at which Great Bay and
Little Bay are able to

                                        19
<PAGE>

sell their share of the Seabrook Project electricity decrease from current price
levels, the Company or its wholly-owned subsidiaries would be required to raise
additional capital, either through a debt financing or an equity financing, to
meet ongoing cash requirements. In that event, the Company and its wholly owned
subsidiaries would likely need to raise additional capital from outside sources.
There is no assurance that the Company or its subsidiaries would be able to
raise such capital or that the terms on which any additional capital is
available would be acceptable. If additional funds are raised by issuing equity
securities, dilution to then existing stockholders will result.

     Primary Reliance on a Single Asset.  BayCorp's principal source of revenue
is its wholesale electricity generation and trading business, which depends in
large part on Great Bay and Little Bay's 15% combined joint interest in the
Seabrook Nuclear Power Project in Seabrook, New Hampshire. Accordingly,
BayCorp's results of operations significantly depend on the successful and
continued operation of the Seabrook Project. In particular, if the Seabrook
Project experiences unscheduled outages of significant duration, BayCorp's
results of operations will be materially adversely affected.

     Risks Associated with Agreement to Sell Seabrook Ownership Interests.  On
October 10, 2000, the Company, Great Bay and Little Bay entered into an
agreement with Northeast Utilities ("NU") under which Great Bay and Little Bay
will join with NU in the sale of NU's ownership interests in the Seabrook
Project. Under the terms of the agreement, BayCorp will receive the sales price
established by an auction process led by NU. Although the auction process began
in the last quarter of 2001 with a closing expected in the last quarter of 2002,
the Company cannot control the procedure or timing of the joint sale of the
Seabrook Project, and the sale may be delayed, abandoned or otherwise affected
by factors beyond the Company's control. Significantly, the price obtained by
Great Bay and Little Bay in the sale of their Seabrook interests cannot be
predicted. Further, the value of the fuel and inventory owned by Great Bay and
Little Bay, currently estimated at between $10 million to $14 million, may be
materially different than estimated.

     Changes in the New England Wholesale Power Market.  During recent years in
New England, the combination of (1) small increases in the demand for
electricity and (2) electric industry deregulation has resulted in increased
uncertainty regarding the price of electricity in the wholesale power market.
Although Great Bay's average selling price per kWh (determined by dividing total
sales revenue by the total number of kWhs sold in the applicable period)
increased from 3.13 cents in 1999 to 3.87 cents in 2000 and to 4.29 cents in
2001, there can be no assurance that Great Bay or Little Bay will be able to
sell their power at these prices or higher prices in the future.

     Risks in Connection with Joint Ownership of Seabrook Project.  Great Bay
and Little Bay are required under the JOA to pay their share of Seabrook Unit 1
and Seabrook Unit 2 expenses, including without limitation operations and
maintenance expenses, construction and nuclear fuel expenditures and
decommissioning costs, regardless of Seabrook Unit 1's operations. Under certain
circumstances, a failure by Great Bay or Little Bay to make their monthly
payments under the JOA entitles certain other joint owners of the Seabrook
Project to purchase Great Bay or Little Bay's interest in the Seabrook Project
for 75% of the then fair market value thereof.

     In addition, the failure to make monthly payments under the JOA by owners
of the Seabrook Project other than Great Bay and Little Bay may have a material
adverse effect on the Company. For example, Great Bay or Little Bay could opt to
pay a greater proportion of the Seabrook Project expenses in order to preserve
the value of their share of the Seabrook Project. In the past, certain of the
owners of the Seabrook Project other than Great Bay and Little Bay have not made
their full respective payments. The electric utility industry is undergoing
significant changes as competition and deregulation are introduced into the
marketplace. If a Participant other than Great Bay or Little Bay filed for
bankruptcy and that Participant was unable to pay its share of Seabrook Project
expenses, Great Bay or Little Bay might opt to pay a greater portion of Seabrook
Project expenses in order to preserve the value of their share of the Seabrook
Project. In the past, the filing of bankruptcy by a Participant has not resulted
in a failure to pay Seabrook Project expenses or an increase in the percentage
of expenses paid by other Participants.

     The Seabrook Project is owned by Great Bay, Little Bay and the other owners
thereof as tenants in common, with the various owners holding varying ownership
shares. This means that Great Bay and Little

                                        20
<PAGE>

Bay, which together own only a 15% interest, do not have control of the
management of the Seabrook Project. As a result, decisions may be made affecting
the Seabrook Project notwithstanding Great Bay and/or Little Bay's opposition.

     Certain costs and expenses of operating the Seabrook Project or owning an
interest therein, such as certain insurance and decommissioning costs, are
subject to increase or retroactive adjustment based on factors beyond the
control of BayCorp or its subsidiaries. The cost of disposing of Unit 2 of the
Seabrook Project is not known at this time. These various costs and expenses may
adversely affect BayCorp, Great Bay and Little Bay, possibly materially.

     Extensive Government Regulation.  The Seabrook Project is subject to
extensive regulation by federal and state agencies. In particular, the Seabrook
Project, and Great Bay and Little Bay as part owners of a licensed nuclear
facility, are subject to the broad jurisdiction of the NRC, which is empowered
to authorize the siting, construction and operation of nuclear reactors after
consideration of public health and safety, environmental and antitrust matters.
Great Bay and Little Bay are also subject to the jurisdiction of the FERC and,
as a result, are required to file with FERC all contracts for the sale of
electricity. FERC's jurisdiction also includes, among other things, the sale,
lease, merger, consolidation or other disposition of facilities, interconnection
of certain facilities, accounts, service and property records. Noncompliance
with NRC requirements may result, among other things, in a shutdown of the
Seabrook Project.

     The NRC has promulgated a broad range of regulations affecting all aspects
of the design, construction and operation of a nuclear facility, such as the
Seabrook Project, including performance of nuclear safety systems, fire
protection, emergency response planning and notification systems, insurance and
quality assurance. The NRC retains authority to modify, suspend or withdraw
operating licenses, such as the license pursuant to which the Seabrook project
operates, at any time that conditions warrant. For example, the NRC might order
Seabrook Unit 1 shut down (i) if flaws were discovered in the construction or
operation of Seabrook Unit 1, (ii) if problems developed with respect to other
nuclear generating plants of a design and construction similar to Unit 1, (iii)
if accidents at other nuclear facilities suggested that nuclear generating
plants generally were less safe than previously believed or (iv) if security
measures activated immediately after the attacks of September 11, 2001, or as a
result of the NRC's safety order on February 25, 2002, were deemed insufficient
or inadequate.

     Risk of Nuclear Accident.  Nuclear reactors have been used to generate
electric power for more than 35 years and there are currently 103 nuclear
reactors operating for electric power generation in the United States. Although
the safety record of these nuclear reactors in the United States generally has
been very good, accidents and other unforeseen problems have occurred both in
the United States and elsewhere, including the well-publicized incidents at
Three Mile Island in Pennsylvania and Chernobyl in the former Soviet Union. The
consequences of such an accident can be severe, including loss of life and
property damage, and the available insurance coverage may not be sufficient to
pay all the damages incurred.

     Risk of Terrorist Attack.  With continued uncertainty about the possibility
of additional terrorist activities in the United States, the Nation's nuclear
power plants, including the Seabrook Project, remain at a high level of
security. On February 25, 2002, the NRC issued an order to all nuclear plant
licensees, requiring them to take certain additional interim compensatory
measures to address the generalized high-level threat environment. These
additional compensatory requirements will provide the NRC with reasonable
assurance that public health and safety and the common defense and security
continue to be adequately protected in the current generalized high-level threat
environment. These requirements will remain in effect pending notification from
the NRC that a significant change in the threat environment occurs, or until the
NRC determines that other changes are needed following a more comprehensive
reevaluation of current safeguards and security programs. Compliance with these
requirements will result in additional incremental operating and capital costs.
Should additional security measures be required by the NRC, additional operating
or capital costs could be incurred at the Seabrook Project. These costs could be
substantial. The consequences of a terrorist attack could be severe, including
loss of life and property damage, and the available insurance coverage may not
be sufficient to pay all the damages incurred.

                                        21

     Waste Disposal; Decommissioning Cost.  There has been considerable public
concern and regulatory attention focused upon the disposal of low- and
high-level nuclear wastes produced at nuclear facilities and the ultimate
decommissioning of such facilities. As to waste disposal concerns, both the
federal government and the State of New Hampshire are currently delinquent in
the performance of their statutory obligations.

     The joint owners of the Seabrook Project, through their managing agent
NAESCO, entered into contracts with the DOE for high-level waste disposal in
accordance with the NWPA. Under these contracts and the NWPA, the DOE was
required to take title to and dispose of the Seabrook Project's high-level waste
beginning no later than January 31, 1998. The DOE has not met its contractual
and statutory requirements under the NWPA calling for the DOE to begin accepting
spent fuel from the industry by January 1998. The DOE announced that its first
high-level waste repository would not be in operation until 2010 at the
earliest.

     The Seabrook Project increased its on-site storage capacity for low-level
waste ("LLW") in 1996 and that capacity is expected to be sufficient to meet the
Project's storage requirements through 2006. In addition, the managing agent of
the Seabrook Project has advised the Joint Owners that the Seabrook Project has
adequate on-site storage capacity for high-level waste until approximately 2008.
If the Seabrook Project were unable to store nuclear waste on site or make other
disposal provisions, the Company's business, results of operations and financial
condition would be materially and adversely affected. See "Business -- Nuclear
Waste Disposal."

     As to decommissioning, NRC regulations require that upon permanent shutdown
of a nuclear facility, appropriate arrangements for full decontamination and
decommissioning of the facility be made. These regulations require that during
the operation of a facility, the owners of the facility must set aside
sufficient funds to defray decommissioning costs. While the owners of the
Seabrook Project are accumulating monies in a trust fund to defray
decommissioning costs, these costs could substantially exceed the value of the
trust fund, and the owners (including Great Bay and Little Bay) would remain
liable for the excess. Moreover, the amount that is required to be deposited in
the trust fund is subject to periodic review and adjustment by an independent
commission of the State of New Hampshire, which could result in material
increases in such amounts.

     Risks Related to HoustonStreet.  HoustonStreet's revenues depend on
continued and expanded use of Internet-based wholesale energy trading platforms.
Electronic trading of wholesale energy is new and evolving, and thus may not
achieve widespread market acceptance or emerge as a sustainable business. In
addition, HoustonStreet will need to enhance trading liquidity in order to
increase and sustain revenues. As a technology dependent business,
HoustonStreet's business could suffer due to computer or communications systems
interruptions or failures, technological change or adverse competitive
developments. Further, as electronic commerce evolves, federal, state and
foreign agencies could adopt regulations covering issues such as user privacy,
content and taxation of products and services. If enacted, government
regulations could materially adversely affect HoustonStreet's business. Although
HoustonStreet currently is not aware that it infringes any other patents, it is
possible that HoustonStreet's technology infringes patents held by third
parties. If HoustonStreet were to be found infringing, the owner of the patent
could sue HoustonStreet for damages, prevent HoustonStreet from making, selling
or using the owner's patented technology or could impose substantial royalty
fees for those privileges. If any of the foregoing risks materialize, or other
risks develop that adversely affect HoustonStreet, or if HoustonStreet fails to
grow its revenues and net income, BayCorp could lose all of the value of its
investment in HoustonStreet.

CRITICAL ACCOUNTING POLICIES

     Preparation of the Company's financial statements in accordance with
generally accepted accounting principles requires Management to make estimates
and assumptions that affect the reported amounts of assets and liabilities, the
disclosures of contingent assets and liabilities and revenues and expenses. Note
1 to the Consolidated Financial Statements is a summary of the significant
accounting policies used in the preparation of the Company's financial
statements. The following is a discussion of the most critical accounting
policies used by the Company.

                                        22
<PAGE>

  Decommissioning

     Based on the Financial Accounting Standards Board's ("FASB") tentative
conclusions, reflected on the February 7, 1996, Exposure Draft titled
"Accounting for Certain Liabilities Related to Closure and Removal of Long-Lived
Assets" Great Bay and Little Bay have recognized as a liability their
proportionate share of the present value of the estimated cost of Seabrook
Project decommissioning. For Great Bay, the initial recognition of this
liability was capitalized as part of the Fair Value of the Utility Plant at
November 23, 1994. For Little Bay, the amount was provided for in the purchase
price allocation.

     New Hampshire enacted a law in 1981 requiring the creation of a
state-managed fund to finance decommissioning of any nuclear units in the state.
The Seabrook Project's decommissioning estimate and funding schedule is subject
to review each year by the New Hampshire Nuclear Decommissioning Financing
Committee ("NDFC"). This estimate is based on a number of assumptions. Changes
in assumptions for such things as labor and material costs, technology,
inflation and timing of decommissioning could cause these estimates to change,
possibly materially, in the near term. During November 2001, the NDFC issued an
order which established a decommissioning funding schedule in anticipation of
the sale of a majority of the ownership interests in Seabrook. The NDFC set an
accelerated funding schedule for the years 2002 through 2006. For the years 2007
and beyond, the funding schedule assumes contributions will be made until 2026.
The order also established the requirement for a lump sum "top-off" payment at
closing. The current estimated cost to decommission the Seabrook Project (based
on NDFC Docket 2001-1) is approximately $555.6 million in 2001 dollars, assuming
for decommissioning funding purposes, a remaining 24-year life for the facility
and a future cost escalation of 5.25%.

     Great Bay and Little Bay, based on the initial exposure draft, have been
recognizing a liability based on the present value of the estimated future cash
outflows required to satisfy their obligations using a risk free rate. As of
December 31, 2001, the estimated undiscounted cash outflows for Great Bay and
Little Bay, for decommissioning, based on the November 2001 NDFC study, with
decommissioning expenditures starting in 2024 and being completed in 2046, was
$418.3 million, which discounted at an average rate of 4.75%, over the funding
period, to December 31, 2001, represented a liability of $85.5 million reflected
in the accompanying balance sheet. As of December 31, 2000, and based on the
prior NDFC study, the estimated undiscounted cash outflows for Great Bay and
Little Bay, for decommissioning expenditures, starting in 2013 and being
completed in 2042 was $217.2 million, which discounted at an average rate of
4.75%, over the funding schedule to December 31, 2000 represented a liability of
$71.6 million reflected in the accompanying consolidated balance sheet. In
accordance with the original exposure draft, the company's wholly-owned
subsidiaries record any adjustments to the decommissioning liability due to
changes in estimates in the utility plant account.

     Great Bay and Little Bay accrete their share of the Seabrook Project's
decommissioning liability. This accretion is a non-cash charge and recognizes
their liability related to the closure and decommissioning of their nuclear
plant in current year dollars over the licensing period of the plant. The
non-cash accretion charge recorded in the accompanied consolidated statements of
income was $3,261,000, $3,633,000 and $3,329,000 for the years ended December
31, 2001, 2000 and 1999. The change in the accretion between years reflects
adjustments to the estimated decommissioning by the NDFC.

     Funds collected by Seabrook for decommissioning are deposited in an
external irrevocable trust pending their ultimate use. The earnings on the
external trusts also accumulate in the fund balance. The trust funds are
restricted for use in paying the decommissioning of Unit 1. The investments in
the trust are available for sale. Great Bay and Little Bay have therefore
reported their investment in trust fund assets at market value and any
unrealized gains and losses are reflected in equity. There was an unrealized
holding gain of $221,700 and $338,100 as of December 31, 2001 and 2000.

     Although the owners of Seabrook are accumulating funds in an external trust
to defray decommissioning costs, these costs could substantially exceed the
value of the trust fund, and the owners, including Great Bay and Little Bay,
would remain liable for the excess.

                                        23
<PAGE>

     On November 15, 1992, Great Bay, the Bondholder's Committee and the
Predecessor's former parent, Eastern Utilities ("EUA") entered into a settlement
agreement that resolved certain proceedings against EUA brought by the
Bondholder's Committee. Under the settlement agreement EUA reaffirmed its
guarantee of up to $10 million of Great Bay's future decommissioning costs of
Seabrook Unit 1.

  Seabrook Outage Costs

     The Company's operating results and the comparability of these results on
an interim and annual basis are directly impacted by the operations of the
Seabrook Project, including the cyclical refueling outages (generally 18 months
apart) as well as unscheduled outages. During outage periods at the Seabrook
Project, Great Bay and Little Bay have no electricity for resale from the
Seabrook Project and consequently no related revenues. Therefore the impact of
outages on the Company's and Great Bay's and Little Bay's results of operations
and financial position are materially adverse.

     Great Bay and Little Bay accrue for the incremental costs of the Seabrook
Project's scheduled outages over the periods between those outages. However,
Great Bay and Little Bay continue to expense the normal Seabrook operating and
maintenance expenses as incurred. Therefore, the Company will incur losses
during scheduled outage periods as a result of the combination of the lack of
revenue and the recognition of normal recurring operation and maintenance costs
as well as the continuing depreciation of the utility plant. At the Seabrook
Project, a scheduled refueling outage began on October 21, 2000. Seabrook
resumed full operating capacity on February 1, 2001. Seabrook Project management
have scheduled the next outage to begin in May 2002. The 2002 outage has an
estimated incremental operations and maintenance cost of $32 million. The
Company's share is approximately $4.8 million. The estimate is based on a number
of assumptions. Changes in assumptions for such things as labor and contractor
costs, required repairs and days to perform the outage and plant operations in
the interim, could cause this estimate to change.

  Principles of Consolidation

     The Consolidated Financial Statements include the accounts of the Company
and all its subsidiaries. The Company consolidates all majority-owned and
controlled subsidiaries and applies the equity method of accounting for
investments between 20% and 50%. All significant intercompany transactions have
been eliminated. At December 31, 1999, BayCorp owned 100% of HoustonStreet. As
of December 31, 2000 and as of December 31, 2001, the Company owned 45.9% of
HoustonStreet. Therefore, during 2000, the Company deconsolidated HoustonStreet.
At December 31, 2000 and December 31, 2001, the Company accounts for this
investment on the equity method and is presenting the 1999 financial statement
on a comparative basis (see Note 12.) The Company has an agreement with
HoustonStreet under which it is providing certain accounting and administrative
services to HoustonStreet for the periods April 1999 to December 2001 and for
the calendar year 2002. Income related to such services was $165,000 for the
period ending December 31, 2001.

  Energy Marketing

     The Company utilized unit contingent and firm forward sales contracts to
maximize the value of its 174 MW power supply from the Seabrook Project. The
Company had not entered into any forward firm energy trading contracts as of
December 31, 2001, nor does it expect to in 2002, in light of its expected sale
of its ownership interest in the Seabrook Project in 2002. As a result, as of
December 31, 2001, the Company had no unrealized loss or gain on the
mark-to-market of forward firm energy trading contracts recorded in accrued
expenses. The net change in unrealized gain on trading activities for the year
ended December 31, 2001 was $12,879,000 and is included in the accompanying
consolidated statement of income for 2001. As of December 31, 2000, the Company
had a net unrealized loss of approximately $12,879,427 recorded in accrued
expenses. The net change in unrealized loss on trading activities for the year
ended December 31, 2000 was $12,232,000 and is included in the accompanying
consolidated statement of income for 2000.

RECENT ACCOUNTING PRONOUNCEMENTS

     Asset Retirement Obligations:  The Staff of the Securities and Exchange
Commission ("SEC") has questioned certain of the current accounting practices of
the electric utility industry regarding the recognition, measurement and
classification of decommissioning costs for nuclear generating stations and
joint owners in the financial statements of these entities. In response to these
questions, the FASB agreed to review the accounting for nuclear decommissioning
costs. On February 17, 2000 the FASB issued a "Revision of Exposure Draft issued
February 7, 1996, Proposed Statement of Financial Accounting Standards:
Accounting for Obligations Associated with the Retirement of Long-Lived Assets."
On June 30, 2000, the respective proposed statement was issued by the FASB. In
August 2001, the FASB approved the issuance of Statement of Financial Accounting
Standards (SFAS) No. 143, "Accounting for Retirement Obligations." SFAS No. 143
provides accounting requirements for the recognition and measurement of
liabilities associated with the retirement of long-lived assets and requires
entities to record the fair value of a liability for an asset retirement
obligation in the period in which it is incurred. Great Bay's and Little Bay's
accounting for decommissioning is based on the FASB's original tentative
conclusions. The new statement requires that an obligation associated with the
retirement of a tangible long-lived asset be recognized as a liability when
incurred, and that the amount of the liability resulting from (a) the passage of
time and (b) revisions to either the timing or amount of estimated cash flows
should also be recognized. The new statement also requires that, upon initial
recognition of a liability for an asset retirement obligation, an entity
capitalize that cost by recognizing an increase in the carrying amount of the
related long-lived asset.

     The new statement requires the initial measurement of the liability to be
based on fair value, where the fair value is the amount that an entity would be
required to pay in an active market to settle the asset retirement obligation in
a current transaction in circumstances other than a forced liquidation or
settlement. Because in most circumstances, a market for settling asset
retirement obligations does not exist, the FASB described an expected present
value technique for estimating fair value. If the new statement is adopted,
Great Bay's and Little Bay's decommissioning liability and annual provision for
decommissioning accretion could change relative to 2001. The new statement is
effective for fiscal years beginning after June 15, 2002, with earlier adoption
encouraged. Great Bay and Little Bay have not quantified the impact, if any,
that the new statement will have on the consolidated financial statements.

     Impairment or Disposal of Long-Lived Assets:  In October 2001, the FASB
issued SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived
Assets ("SFAS No. 144") which replaces SFAS No. 121, Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of.
This statement addresses financial accounting and reporting for the impairment
or disposal of long-lived assets. Although SFAS No. 144 supercedes SFAS No. 121,
it retains the fundamental provisions of SFAS No. 121 regarding
recognition/measurement of impairment of long-lived assets to be held and used
and measurement of long-lived assets to be disposed of by sale. Under SFAS No.
144, asset write-downs from discontinuing a business segment will be treated the
same as other assets held for sale. The new standard also broadens the financial
statement presentation of discontinued operations to include the disposal of an
asset group (rather than a segment of a business). SFAS No. 144 is effective
beginning January 1, 2002 and, generally, is to be applied prospectively. The
Company does not expect that SFAS No. 144 will have a significant impact on its
financial position or results of operations.

ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK.

COMMODITY PRICE RISK

     The prices of electricity are subject to fluctuations resulting from
changes in supply and demand. Great Bay sold a portion of its electricity
through forward, fixed-price energy trading contracts in prior years, including
in 2001. Until December 31, 2001, Great Bay tracked its market exposure for
these forward energy trading contracts in a mark-to-market model that was
updated daily with current market prices and is reflected in the company's
balance sheet. See "Note 5 -- Energy Marketing." The positive, or negative,
value of Great Bay's portfolio of firm power commitments represented an
estimation of the gain, or loss, that Great Bay

                                        25

would have experienced if open firm commitments were covered at then-current
market prices. As of December 31, 2001, Great Bay had no firm forward, fixed
energy trading contracts.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors of
BayCorp Holdings, Ltd.

     We have audited the accompanying consolidated balance sheets of BayCorp
Holdings, Ltd. (a Delaware corporation) and its wholly-owned subsidiaries, as of
December 31, 2001 and 2000, and the related consolidated statements of income
and comprehensive income, changes in stockholders' equity and cash flows for
each of the three years in the period ended December 31, 2001. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

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

     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of BayCorp
Holdings, Ltd. and its wholly-owned subsidiaries as of December 31, 2001 and
2000, and the results of their operations and cash flows for each of the three
years in the period ended December 31, 2001, in conformity with accounting
principles generally accepted in the United States.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               DECEMBER 31, 2001

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

A.  THE COMPANY

     BayCorp Holdings, Ltd. ("BayCorp" or the "Company") is a holding company
incorporated in Delaware in 1996. BayCorp owns two subsidiaries that generate
and trade wholesale electricity, Great Bay Power Corporation ("Great Bay") and
Little Bay Power Corporation ("Little Bay"), each of which was wholly-owned as
of December 31, 2001. In addition, BayCorp owns 45.9% of HoustonStreet Exchange,
Inc. ("HoustonStreet"), an Internet-based independent crude oil and refined
products trading exchange.

     Great Bay and Little Bay are electric generating and trading companies.
Their principal asset is a combined 15% joint ownership interest in the Seabrook
Nuclear Power Project in Seabrook, New Hampshire (the "Seabrook Project" or
"Seabrook"). This ownership interest entitles the companies to approximately 174
megawatts ("MWs") of the Seabrook Project's power output. Great Bay and Little
Bay are exempt wholesale generators ("EWGs") under the Public Utility Holding
Company Act of 1935 ("PUHCA"). Unlike regulated public utilities, Great Bay and
Little Bay have no franchise area or captive customers. The companies sell their
power in the competitive wholesale power markets.

     Great Bay was incorporated in New Hampshire in 1986 and was formerly known
as EUA Power Corporation. Little Bay was incorporated in New Hampshire in 1998.
Great Bay sells its power, including its share of the electricity output of the
Seabrook Project, in the wholesale electricity market, primarily in the
Northeast United States. Little Bay sells its power solely to Great Bay under an
intercompany agreement. Neither BayCorp nor its subsidiaries have operational
responsibilities for the Seabrook Project. Great Bay currently sells all but
approximately 10 MWs of its share of the Seabrook Project capacity in the
wholesale short-term market. In addition to selling the power it owns generated
by Seabrook, Great Bay purchases power on the open market for resale to third
parties.

     In November 1999, Little Bay purchased an additional 2.9% interest in the
Seabrook Project from Montaup Electric Company ("Montaup"), a subsidiary of
Eastern Utilities Associates ("EUA"), for a purchase price of $3.2 million, plus
approximately $1.7 million for certain prepaid items, primarily nuclear fuel and
capital expenditures. In addition, Montaup prefunded the decommissioning
liability associated with Little Bay's 2.9% share of Seabrook by transferring
approximately $12.4 million into Little Bay's decommissioning account, an
irrevocable trust earmarked for Little Bay's share of Seabrook Project
decommissioning expenses.

     The Seabrook Project is a nuclear-fueled, steam electricity, generating
plant located in Seabrook, New Hampshire, which was originally planned to have
two Westinghouse pressurized water reactors, Seabrook Unit 1 and Seabrook Unit 2
(each with a rated capacity of 1,150 megawatts), utilizing ocean water for
condenser cooling purposes. Seabrook Unit 1 entered commercial service on August
19, 1990. Seabrook Unit 2 has been canceled. Great Bay became a wholesale
generating company when Seabrook Unit 1 commenced commercial operation on August
19, 1990. In 1993, the Company became an EWG under the Energy Policy Act of
1992.

     The Seabrook Project is owned by Great Bay, Little Bay and nine other
utility companies, consisting of North Atlantic Energy Company, Connecticut
Light and Power, The United Illuminating Company, Canal Electric Company,
Massachusetts Municipal Wholesale Electric Company, New England Power Company,
New Hampshire Electric Cooperative, Inc., Taunton Municipal Lighting Plant and
Hudson Light & Power Department (together with Great Bay and Little Bay, the
"Participants"). Great Bay, Little Bay and the other Participants are parties to
the Agreement for Joint Ownership, Construction and Operation of New Hampshire
Nuclear Units (the "JOA"), which establishes the respective ownership interests
of the Participants in the Seabrook Project and defines their responsibilities
with respect to the ongoing operation, maintenance and decommissioning of the
Seabrook Project. In general, all ongoing costs of the Seabrook Project are
divided proportionately among the Participants in accordance with their
ownership interests in the

                                       F-6

                   NOTES TO FINANCIAL STATEMENTS -- CONTINUED

Seabrook Project. Each Participant is only liable for its share of the Seabrook
Project's costs and not liable for any other Participant's share as ownership
interests in the Seabrook Project are several and not joint. Great Bay's and
Little Bay's combined joint ownership interest of 15% is the third largest
interest among the Participants, exceeded only by the approximately 40% interest
held by Northeast Utilities ("NU") and its affiliates and the 17.5% interest
held by The United Illuminating Company.

     In October 2000, the Company announced that it had reached an agreement
with NU under which the Company's generating subsidiaries, Great Bay and Little
Bay, will include their aggregate 15% ownership share of the Seabrook Project in
the upcoming auction of NU's subsidiaries' shares of the Seabrook Project. Under
the terms of the agreement, BayCorp will receive the sales price established by
the auction process. In the event that the sale yields proceeds for BayCorp of
more than $87.2 million, BayCorp and NU will share the excess proceeds. Should
BayCorp's sales proceeds be less than $87.2 million, NU will make up the
difference below that amount on a dollar for dollar basis up to a maximum of
$17.4 million. Under the agreement, BayCorp will be paid separately for nuclear
fuel and inventory. The agreement also limits any top-off amount required to be
funded by BayCorp for decommissioning as part of the sale process at the amount
required by the Nuclear Regulatory Commission ("NRC") regulations.

     In October 2001, the Company announced that the New Hampshire Public
Utilities Commission ("NHPUC") and the Connecticut Department of Public Utility
Control ("CDPUC") selected J.P. Morgan as their financial advisor for the sale
of ownership interests in the Seabrook Project. J.P. Morgan will manage the sale
under the oversight of the NHPUC and the CDPUC. J.P. Morgan managed the recent
sales of the Millstone and Vermont Yankee nuclear plants. In December 2001, the
NHPUC in coordination with the CDPUC, announced the start of the auction of
88.2% of the ownership shares of the Seabrook Project. BayCorp anticipates the
closing of the sale in the fourth quarter of 2002.

     With continued uncertainty about the possibility of additional terrorist
activities in the United States, the Nation's nuclear power plants, including
the Seabrook Project, remain at a high level of security. On February 25, 2002,
the NRC issued an order to all nuclear plant licensees, requiring them to take
certain additional interim compensatory measures to address the generalized
high-level threat environment. These additional compensatory requirements will
provide the NRC with reasonable assurance that public health and safety and the
common defense and security continue to be adequately protected in the current
generalized high-level threat environment. These requirements will remain in
effect pending notification from the NRC that a significant change in the threat
environment occurs, or until the NRC determines that other changes are needed
following a more comprehensive reevaluation of current safeguards and security
programs. Seabrook remains at a high level of security and the management of
Seabrook has assured the joint owners of Seabrook that it will take actions
necessary to comply with the NRC order setting out the requirements for interim
compensatory measures. Compliance with these requirements will result in
additional incremental operating and capital costs. Should additional security
measures be required by the NRC, additional operating or capital costs could be
incurred at the Seabrook Project.

     Traditionally, Great Bay sold most of its share of the Seabrook Project
electricity output under unit contingent contracts. Under unit contingent
contracts, Great Bay is obligated to provide the buyer with power only when the
Seabrook Project is operating. In late 1998, Great Bay began to sell some of its
electricity as firm power, which entitles the buyer to electricity whether or
not the Seabrook Project is operating. Buyers pay a premium for firm power over
unit contingent power because they can rely on uninterrupted electricity. In
order to supply firm power during unscheduled outages at the Seabrook Project,
Great Bay purchases power from the spot market during these outages and resells
that power to its firm power customers. Spot market sales are subject to price
fluctuations based on the relative supply and demand of electricity. As a result
of spot market power price fluctuations, Great Bay may have to purchase power at
prices exceeding prices paid by Great Bay's firm power customers during outages.
Although Great Bay bears the primary risk of these price fluctuations, Great Bay
maintained insurance in 2001 and 2000 to protect Great Bay during periods of
extreme

price volatility, subject to certain deductibles and coverage limits. Great Bay
has not entered into any firm power contracts for 2002 given the expected sale
of the Seabrook Project in 2002. In December 2001, Great Bay negotiated a buyout
of the remaining insurance policy it held due to the absence of any firm sales
during 2002. Without firm contracts, the insurance was not needed as protection
against replacement power costs.

     As of March 15, 2002, BayCorp had eleven employees. BayCorp's subsidiaries,
Great Bay and Little Bay, had no employees. HoustonStreet had six employees.

     HoustonStreet was incorporated in Delaware in 1999. HoustonStreet is an
equity investment of BayCorp. HoustonStreet developed and operates
HoustonStreet.com, an Internet-based independent crude oil and refined products
trading exchange. HoustonStreet offers this online trading platform for
over-the-counter crude oil and refined products in the United States.

     As of December 31, 1999, the Company owned 100% of HoustonStreet.
HoustonStreet raised additional equity in 2000 from outside investors and as a
result, as of December 4, 2000, the Company's ownership fell below 50%, to
45.9%. Subsequently, the Company deconsolidated HoustonStreet as of December 4,
2000 and started accounting for this investment on the equity method.

     On March 21, 2001, HoustonStreet raised approximately $2.9 million in
additional funding, including $450,000 from BayCorp, by selling senior secured
notes, warrants to purchase HoustonStreet preferred stock and warrants to
purchase HoustonStreet common stock. Collectively, these securities are referred
to as the "HoustonStreet Series C Units." In April 2001, BayCorp authorized
HoustonStreet to convert BayCorp's $7,000,000 loan made in 2000, along with
approximately $1,000,000 in accrued interest and penalties on the note and past
due management fees, into $8,000,000 of Series C Units. The loan, accrued
interest and receivables from HoustonStreet had been written down to zero as of
December 31, 2000 and as such, the conversion of these amounts had no accounting
impact on BayCorp.

     In 2001, HoustonStreet made the decision to downsize its organization and
to focus its efforts on its crude oil and refined products trading platforms.
HoustonStreet shut down its electricity-trading platform in the second half of
2001. As of March 15, 2002, HoustonStreet had six employees.

     On October 2, 2000, the Seabrook Project began a refueling outage with a
return to full power operation planned for November 21, 2000. The outage was
extended when damage to one of the plant's emergency diesel generators occurred,
requiring an extensive repair effort. The Seabrook Project did not return to
full power until February 1, 2001. The replacement power costs, normal operating
costs and additional costs of the extended outage significantly impacted
earnings and cash flow.

     The Seabrook outage and HoustonStreet loan impacted the Company's
unrestricted cash, which was approximately $3,500,000 as of February 8, 2001. To
deal with the adverse effects of these events the Company entered into an
agreement with Select Energy ("Select"), (see Note 6) whereby Select prepaid
approximately $7,000,000 to the Company for power purchases.

B.  REGULATION

     Great Bay and Little Bay are subject to the regulatory authority of the
Federal Energy Regulatory Commission ("FERC"), the NRC, the NHPUC and other
federal and state agencies as to rates, operations and other matters. Great
Bay's and Little Bay's cost of service, however, is not regulated. As such,
Great Bay's and Little Bay's accounting policies are not subject to the
provisions of Statement of Financial Accounting Standards ("SFAS") No. 71,
"Accounting for the Effects of Certain Types of Regulation."

C.  USE OF ESTIMATES

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and


                                       F-8

                             BAYCORP HOLDINGS, LTD.

                   NOTES TO FINANCIAL STATEMENTS -- CONTINUED

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.

D.  UTILITY PLANT

     The costs of additions to utility plant and non-utility plant are recorded
at original cost.

E.  DEPRECIATION

     Utility plant is depreciated on the straight-line method at rates designed
to fully depreciate all depreciable properties over the lesser of estimated
useful lives or the Seabrook Project's remaining NRC license life, which expires
in 2026.

     Capital projects constituting retirement units are charged to electric
plant. Minor repairs are charged to maintenance expense. When properties are
retired, the original costs, plus costs of removal, less salvage, are charged to
the accumulated provision for depreciation.

F.  AMORTIZATION OF NUCLEAR FUEL

     The cost of nuclear fuel is amortized to expense based on the rate of
burn-up of the individual assemblies comprising the total core. Great Bay and
Little Bay also provide for the cost of disposing of spent nuclear fuel at rates
specified by the United States Department of Energy ("DOE") under a contract for
disposal between Great Bay and Little Bay, through their managing agent North
Atlantic Energy Service Corporation ("NAESCO"), and the DOE.

     Great Bay recorded the estimated cost of the final unspent nuclear fuel
core, which is expected to be in place at the expiration of the Seabrook
Project's NRC operating license, as part of Great Bay's original "Fresh Start"
balance sheet.

G.  AMORTIZATION OF MATERIALS AND SUPPLIES

     Great Bay and Little Bay amortize to expense an amount designed to fully
amortize the cost of the material and supplies inventory that is expected to be
on hand at the expiration of the Plant's NRC operating license.

H.  DECOMMISSIONING

     Based on the Financial Accounting Standards Board's ("FASB") tentative
conclusions, reflected on the February 7, 1996, Exposure Draft titled
"Accounting for Certain Liabilities Related to Closure and Removal of Long-Lived
Assets" Great Bay and Little Bay have recognized as a liability their
proportionate share of the present value of the estimated cost of Seabrook
Project decommissioning. For Great Bay, the initial recognition of this
liability was capitalized as part of the Fair Value of the Utility Plant at
November 23, 1994. For Little Bay, the amount was provided for in the purchase
price allocation.

     New Hampshire enacted a law in 1981 requiring the creation of a
state-managed fund to finance decommissioning of any nuclear units in the state.
The Seabrook Project's decommissioning estimate and funding schedule is subject
to review each year by the New Hampshire Nuclear Decommissioning Financing
Committee ("NDFC"). This estimate is based on a number of assumptions. Changes
in assumptions for such things as labor and material costs, technology,
inflation and timing of decommissioning could cause these estimates to change,
possibly materially, in the near term. During November 2001, the NDFC issued an
order which established a decommissioning funding schedule in anticipation of
the sale of a majority of the ownership interests in Seabrook. The NDFC set an
accelerated funding schedule for the years 2002 through

                                       F-9
<PAGE>
                             BAYCORP HOLDINGS, LTD.

                   NOTES TO FINANCIAL STATEMENTS -- CONTINUED

2006. For the years 2007 and beyond, the funding schedule assumes contributions
will be made until 2026. The order also established the requirement for a lump
sum "top-off" payment at closing. The current estimated cost to decommission the
Seabrook Project (based on NDFC Docket 2001-1) is approximately $555.6 million
in 2001 dollars, assuming for decommissioning funding purposes, a remaining
24-year life for the facility and a future cost escalation of 5.25%.

     The Staff of the Securities and Exchange Commission ("SEC") has questioned
certain of the current accounting practices of the electric utility industry
regarding the recognition, measurement and classification of decommissioning
costs for nuclear generating stations and joint owners in the financial
statements of these entities. In response to these questions, the FASB agreed to
review the accounting for nuclear decommissioning costs. On February 17, 2000
the FASB issued a "Revision of Exposure Draft issued February 7, 1996, Proposed
Statement of Financial Accounting Standards: Accounting for Obligations
Associated with the Retirement of Long-Lived Assets." On June 30, 2000, the
respective proposed statement was issued by the FASB. In August 2001, the FASB
approved the issuance of Statement of Financial Accounting Standards (SFAS) No.
143, "Accounting for Retirement Obligations." SFAS No. 143 provides accounting
requirements for the recognition and measurement of liabilities associated with
the retirement of long-lived assets and requires entities to record the fair
value of a liability for an asset retirement obligation in the period in which
it is incurred. Great Bay's and Little Bay's accounting for decommissioning is
based on the FASB's original tentative conclusions. The new statement requires
that an obligation associated with the retirement of a tangible long-lived asset
be recognized as a liability when incurred, and that the amount of the liability
resulting from (a) the passage of time and (b) revisions to either the timing or
amount of estimated cash flows should also be recognized. The new statement also
requires that, upon initial recognition of a liability for an asset retirement
obligation, an entity capitalize that cost by recognizing an increase in the
carrying amount of the related long-lived asset.

     The new statement requires the initial measurement of the liability to be
based on fair value, where the fair value is the amount that an entity would be
required to pay in an active market to settle the asset retirement obligation in
a current transaction in circumstances other than a forced liquidation or
settlement. Because in most circumstances, a market for settling asset
retirement obligations does not exist, the FASB described an expected present
value technique for estimating fair value. If the new statement is adopted,
Great Bay's and Little Bay's decommissioning liability and annual provision for
decommissioning accretion could change relative to 2001. The new statement is
effective for fiscal years beginning after June 15, 2002, with earlier adoption
encouraged. Great Bay and Little Bay have not quantified the impact, if any,
that the new statement will have on the consolidated financial statements.

     Great Bay and Little Bay, based on the initial exposure draft, have been
recognizing a liability based on the present value of the estimated future cash
outflows required to satisfy their obligations using a risk free rate. As of
December 31, 2001, the estimated undiscounted cash outflows for Great Bay and
Little Bay, for decommissioning, based on the November 2001 NDFC study, with
decommissioning expenditures starting in 2024 and being completed in 2046, was
$418.3 million, which discounted at an average rate of 4.75%, over the funding
period, to December 31, 2001, represented a liability of $85.5 million reflected
in the accompanying balance sheet. As of December 31, 2000, and based on the
prior NDFC study, the estimated undiscounted cash outflows for Great Bay and
Little Bay, for decommissioning expenditures, starting in 2013 and being
completed in 2042 was $217.2 million, which discounted at an average rate of
4.75%, over the funding schedule to December 31, 2000 represented a liability of
$71.6 million reflected in the accompanying consolidated balance sheet. In
accordance with the original exposure draft, the company's wholly-owned
subsidiaries record any adjustments to the decommissioning liability due to
changes in estimates in the utility plant account.

     Great Bay and Little Bay accrete their share of the Seabrook Project's
decommissioning liability. This accretion is a non-cash charge and recognizes
their liability related to the closure and decommissioning of

                                       F-10
<PAGE>
                             BAYCORP HOLDINGS, LTD.

                   NOTES TO FINANCIAL STATEMENTS -- CONTINUED

their nuclear plant in current year dollars over the licensing period of the
plant. The non-cash accretion charge recorded in the accompanied consolidated
statements of income was $3,261,000, $3,633,000 and $3,329,000 for the years
ended December 31, 2001, 2000 and 1999. The change in the accretion between
years reflects adjustments to the estimated decommissioning by the NDFC.

     Funds collected by Seabrook for decommissioning are deposited in an
external irrevocable trust pending their ultimate use. The earnings on the
external trusts also accumulate in the fund balance. The trust funds are
restricted for use in paying the decommissioning of Unit 1. The investments in
the trust are available for sale. Great Bay and Little Bay have therefore
reported their investment in trust fund assets at market value and any
unrealized gains and losses are reflected in equity. There was an unrealized
holding gain of $222,700 and $338,100 as of December 31, 2001 and 2000.

     Although the owners of Seabrook are accumulating funds in an external trust
to defray decommissioning costs, these costs could substantially exceed the
value of the trust fund, and the owners, including Great Bay and Little Bay,
would remain liable for the excess.

     In June 1998, the New Hampshire State legislature enacted legislation that
provides that in the event of a default by Great Bay on its payments to the
decommissioning fund, the other Seabrook joint owners would be obligated to pay
their proportional share of such default. As a result of the enactment of this
legislation, the staff of the NRC notified Great Bay in July 1998 of the staff's
determination that Great Bay complies with the decommissioning funding assurance
requirements under NRC regulations.

     In response to the obligations imposed on the other Joint Owners under the
New Hampshire legislation, Great Bay agreed to make accelerated payments to the
Seabrook decommissioning fund such that Great Bay will have contributed
sufficient funds by the year 2015 to allow sufficient monies to accumulate, with
no further payments by Great Bay to the fund, to the full estimated amount of
Great Bay's decommissioning obligation by the time the current Seabrook
operating license expires in 2026. Based on the currently approved funding
schedule and Great Bay's accelerated funding schedule, Great Bay's
decommissioning payments will be approximately $1.4 million in 2002 and escalate
at 4% each year thereafter through 2015. Little Bay's share of decommissioning
costs was prefunded by Montaup, the owner of the 2.9% interest in the Seabrook
Project that Little Bay acquired in November 1999. As part of that acquisition,
Montaup transferred approximately $12.4 million into Little Bay's
decommissioning account, an irrevocable trust earmarked for Little Bay's share
of Seabrook Plant decommissioning expenses. As of December 31, 2001 the fair
market value of the Little Bay decommissioning account was $13.6 million.

     On November 15, 1992, Great Bay, the Bondholder's Committee and the
Predecessor's former parent, Eastern Utilities ("EUA") entered into a settlement
agreement that resolved certain proceedings against EUA brought by the
Bondholder's Committee. Under the settlement agreement EUA reaffirmed its
guarantee of up to $10 million of Great Bay's future decommissioning costs of
Seabrook Unit 1.

I.  OPERATING REVENUES

     Revenues are recorded on an accrual basis based on billing rates provided
for in contracts and approved by FERC. During the year ended December 31, 2001,
three customers accounted for 32%, 16% and 15% of total operating revenues. For
the year ended December 31, 2000, four customers accounted for 17%, 15%, 14% and
13% of total operating revenues. For the year ended December 31, 1999, two
customers accounted for 29% and 24% of total operating revenues.

J.  TAXES ON INCOME

     The Company accounts for taxes on income under the liability method
required by SFAS No. 109, "Accounting for Income Taxes."

                   NOTES TO FINANCIAL STATEMENTS -- CONTINUED

K.  CASH EQUIVALENTS AND SHORT TERM INVESTMENTS

     For purposes of the Statements of Cash Flows, the Company considers all
highly liquid short-term investments with an original maturity of three months
or less to be cash equivalents. The carrying amounts approximate fair value
because of the short-term maturity of the investments.

     All other short-term investments with a maturity of greater than three
months are classified as available for sale and reflected as a current asset at
market value. Changes in the market value of such securities are reflected in
equity. There were no short-term investments as of December 31, 2001. The
unrealized holding loss on short-term investments was $20,100 as of December 31,
2000.

L.  SEABROOK UNIT 2

     Since the Seabrook Project was originally designed to consist of two
generating units, Great Bay and Little Bay also own a combined 15% joint
ownership interest in Seabrook Unit 2. Great Bay and Little Bay assigned no
value to Seabrook Unit 2 because on November 6, 1986, the joint owners of the
Seabrook Project voted to dispose of Unit 2. Thereafter, Great Bay wrote off its
investment in Unit 2. Little Bay has no investment in Unit 2. Certain assets of
Seabrook Unit 2 have been sold from time to time to third parties. However,
there have been no material sales of Unit 2 assets since July 1996.

     Because Seabrook Unit 2 was never completed or operated, costs associated
with its disposition are not included in the amounts collected for the
decommissioning of Unit 1 and the common facilities. Great Bay and Little Bay
currently pay their share of monthly expenses required to preserve and protect
the value of the Seabrook Unit 2 components. Any sales of Unit 2 property or
inventory are reflected in other income as gains on the sale or transfer of
assets. Transfers of Unit 2 items to Unit 1 were done at the historical basis of
Unit 2 property or components. Seabrook Unit 2 will be sold as part of the
expected sale of the Seabrook Project in 2002. The Participants in Seabrook Unit
1 and Unit 2 have agreed to contribute their pro-rata share of $2 million to an
escrow account for the development and performance of a plan to mitigate the
visual impact of Unit 2. The contribution to the escrow account is scheduled to
occur within 60 days of the closing of the sale of Seabrook.

M.  SEABROOK OUTAGE COSTS

     The Company's operating results and the comparability of these results on
an interim and annual basis are directly impacted by the operations of the
Seabrook Project, including the cyclical refueling outages (generally 18 months
apart) as well as unscheduled outages. During outage periods at the Seabrook
Project, Great Bay and Little Bay have no electricity for resale from the
Seabrook Project and consequently no related revenues. Therefore the impact of
outages on the Company's and Great Bay's and Little Bay's results of operations
and financial position are materially adverse.

     Great Bay and Little Bay accrue for the incremental costs of the Seabrook
Project's scheduled outages over the periods between those outages. However,
Great Bay and Little Bay continue to expense the normal Seabrook operating and
maintenance expenses as incurred. Therefore, the Company will incur losses
during scheduled outage periods as a result of the combination of the lack of
revenue and the recognition of normal recurring operation and maintenance costs
as well as the continuing depreciation of the utility plant. At the Seabrook
Project, a scheduled refueling outage began on October 21, 2000. Seabrook
resumed full operating capacity on February 1, 2001. Seabrook Project management
have scheduled the next outage to begin in May 2002. The 2002 outage has an
estimated incremental operations and maintenance cost of $32 million. The
Company's share is approximately $4.8 million. The estimate is based on a number
of assumptions. Changes in assumptions for such things as labor and contractor
costs, required repairs and days to perform the outage and plant operations in
the interim, could cause this estimate to change.

N.  ACQUISITIONS

     On November 19, 1999, BayCorp's wholly-owned subsidiary, Little Bay,
purchased an additional 2.9% interest in the Seabrook Nuclear Power Project from
Montaup, a subsidiary of EUA. The purchase price was $3.2 million plus
approximately $1.9 million for certain prepaid items, primarily nuclear fuel and
capital expenditures. The purchase price was funded with existing cash. Little
Bay allocated the purchase price based on the estimated fair value of the assets
acquired and liabilities assumed. A summary of the components of the purchase
price and the purchase price allocation is as follows:

<Table>

</Table>

     In addition, Montaup prefunded the decommissioning liability associated
with Little Bay's 2.9% share of Seabrook by transferring approximately $12.4
million into Little Bay's decommissioning account, an irrevocable trust
earmarked for Little Bay's share of the Seabrook Project decommissioning
expenses. Little Bay recorded an asset, Decommissioning Trust Fund, for $12.4
million and a corresponding liability for the same amount. The purchase
agreement required that a restricted cash-escrow account be established to cover
Little Bay's share of budgeted cash requirements for a six-month period. This
fund is used to pay Little Bay's share of Seabrook costs of operations and
capital expenditures during periods of Seabrook shutdowns.

     Little Bay sells its power solely to Great Bay under an intercompany
agreement at cost. Great Bay then sells the power purchased from Little Bay in
the wholesale electricity market. The accompanying consolidated financial
statements include the results of the acquisition since November 19, 1999.
Intercompany amounts between Little Bay and Great Bay have been eliminated in
consolidation.

O.  SEGMENT INFORMATION

     The Company has adopted SFAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information." SFAS No. 131 establishes standards for the
reporting of information about operating segments in annual and interim
financial statements and requires restatement of prior year information.
Operating segments are defined as components of an enterprise for which separate
financial information is available that is evaluated regularly by the chief
operating decision maker(s) in deciding how to allocate resources and in
assessing performance. SFAS No. 131 also requires disclosures about products and
services, geographic areas and major customers. The Company currently operates
only in the electric generating segment in the Northeast United States.

P.  EARNINGS PER SHARE

     Basic earnings (loss) per share is computed by dividing net earnings by the
weighted number of common shares outstanding for all periods presented. Diluted
earnings (loss) per share reflects the dilutive effect of shares under option
plans. Potentially dilutive shares outstanding during 2000 and 1999 have been
excluded from dilutive earnings (loss) per share because their effect would be
antidilutive.

     Based on an average market price of common stock of $9.11 per share for the
year ended December 31, 2001 and $11.35 per share for the year ended December
31, 2000, the following table reconciles the weighted

Q.  ACCUMULATED OTHER COMPREHENSIVE INCOME

     Effective January 1, 1998, the Company adopted SFAS No. 130, "Reporting
Comprehensive Income" which requires the Company to report the changes in
shareholders' equity from all sources during the period other than those
resulting from investments by shareholders (i.e., issuance or repurchase of
common shares and dividends.) Although adoption of this standard has not
resulted in any change to the historic basis of determination of earnings or
shareholders' equity, the other comprehensive income components recorded under
generally accepted accounting principles and previously included under the
category "retained earnings" are displayed as "accumulated other comprehensive
income" within the balance sheet. The composition of other comprehensive income
is as follows:

R.  RECLASSIFICATIONS

     Certain reclassifications have been made in prior years' financial
statements to conform to classifications and presentation used in the current
year.

S.  PRINCIPLES OF CONSOLIDATION

     The Consolidated Financial Statements include the accounts of the Company
and all its majority-owned and controlled subsidiaries. The Company applies the
equity method of accounting for investments between 20% and 50%. All significant
intercompany transactions have been eliminated. At December 31, 1999, BayCorp
owned 100% of HoustonStreet. As of December 31, 2000 and as of December 31,
2001, the Company owned 45.9% of HoustonStreet. Therefore, during 2000, the

administrative services to HoustonStreet for the periods April 1999 to December
2001 and for the calendar year 2002. Income related to such services was
$165,000 for the period ending December 31, 2001.

T.  LONG-LIVED ASSETS AND LONG-LIVED ASSETS TO BE DISPOSED OF.

     SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to Be Disposed Of," requires that long-lived assets held and
used by an entity be reviewed for impairment whenever events or changes in
circumstances indicate that the carrying amount of an asset may not be
recoverable. In performing the review of the recoverability, the entity should
estimate the future cash flows expected to result from the use of the asset and
its eventual disposition. If the sum of the expected future cash flows
(undiscounted and without interest charges) is less than the carrying amount of
the asset, an impairment loss is recognized. Otherwise, an impairment loss is
not recognized. This statement requires that long-lived assets and certain
identifiable intangibles to be disposed of be reported at the lower of carrying
amount or fair value less cost to sell. The sales agreement with NU established
a minimum expected value for the Company's investment in the Seabrook plant. The
Company estimates that the current carrying amount for the respective investment
is the lower of the carrying amount or fair value less cost to sell in
accordance with SFAS No. 121. In October 2001, the FASB issued SFAS No. 144,
"Accounting for the Impairment or Disposal of Long-lived Assets," which replaces
SFAS No. 121. This new statement addresses financial accounting and reporting
for the impairment or disposal of long-lived assets. Although SFAS No. 144
supersedes SFAS No. 121, it retains the fundamental provisions of SFAS No. 121
regarding recognition/measurement of impairment of long-lived assets to be held
and used and measurement of long-lived assets to be disposed of by sale. Under
SFAS No. 144, asset write-downs from discontinuing a business segment will be
treated the same as other assets held for sale. The new statement also broadens
the financial statement presentation of discontinued operations to include the
disposal of an asset group (rather than a segment of a business segment). SFAS
No. 144 is effective beginning January 1, 2002 and, generally is to be applied
prospectively. Although the Company is studying the potential impacts of
adopting this new statement, the Company does not expect it will have a
significant impact on its financial position or results of operations.

2.  NUCLEAR ISSUES

     Like other nuclear generating facilities, the Seabrook Project is subject
to extensive regulation by the NRC. The NRC is empowered to authorize the
siting, construction and operation of nuclear reactors after consideration of
public health, safety, environmental and antitrust matters.

     The NRC has promulgated numerous requirements affecting safety systems,
fire protection, emergency response planning and notification systems and other
aspects of nuclear plant construction, equipment and operation. Great Bay and
Little Bay have been, and may be, affected to the extent of their proportionate
shares by the cost of any such modifications to Seabrook Unit 1.

     Nuclear units in the United States have been subject to widespread
criticism and opposition. Some nuclear projects have been canceled following
substantial construction delays and cost overruns as the result of licensing
problems, unanticipated construction defects and other difficulties. Various
groups have by litigation, legislation and participation in administrative
proceedings sought to prohibit the completion and operation of nuclear units and
the disposal of nuclear waste. In the event of a shutdown of any unit, NRC
regulations require that it be completely decontaminated of any residual
radioactivity. The cost of such decommissioning, depending on the circumstances,
could substantially exceed the owners' investment at the time of cancellation.

     Public controversy concerning nuclear power could adversely affect the
operating license of Seabrook Unit 1. While the Company cannot predict the
ultimate effect of such controversy, it is possible that it could result in a
premature shutdown of the unit.

                   NOTES TO FINANCIAL STATEMENTS -- CONTINUED

     With continued uncertainty about the possibility of additional terrorist
activities in the United States, the Nation's nuclear power plants, including
the Seabrook Project, remain at a high level of security. On February 25, 2002,
the NRC issued an order to all nuclear plant licensees, requiring them to take
certain additional interim compensatory measures to address the generalized
high-level threat environment. These additional compensatory requirements will
provide the NRC with reasonable assurance that public health and safety and the
common defense and security continue to be adequately protected in the current
generalized high-level threat environment. These requirements will remain in
effect pending notification from the NRC that a significant change in the threat
environment occurs, or until the NRC determines that other changes are needed
following a more comprehensive reevaluation of current safeguards and security
programs. Seabrook remains at a high level of security and will take actions
necessary to comply with the NRC order setting out the requirements for interim
compensatory measures. Compliance with these requirements will result in
additional incremental operating and capital costs. Should additional security
measures be required by the NRC, additional operating or capital costs could be
incurred at the Seabrook Project.

A.  NUCLEAR FUEL

     The Seabrook Project's managing agent has made, or expects to make, various
arrangements for the acquisition of uranium concentrate, the conversion,
enrichment, fabrication and utilization of nuclear fuel and the disposition of
that fuel after use. Many of these arrangements are pursuant to multi-year
contracts with concentrate and service providers. Based on the Seabrook
Project's existing contractual arrangements, Great Bay and Little Bay believe
that the Seabrook Project has available, or under supply contracts, sufficient
nuclear fuel for operations through approximately 2004. Uranium concentrate and
conversion, enrichment and fabrication services currently are available from a
variety of sources. The cost of such concentrate and such services varies based
upon market forces.

     Costs associated with nuclear plant operations include amounts for nuclear
waste disposal, including spent fuel, as well as for the ultimate
decommissioning of the plants. The Nuclear Waste Policy Act of 1982 (the "NWPA")
requires the DOE, subject to various contingencies, to design, license,
construct and operate a permanent repository for high-level radioactive waste
and spent nuclear fuel, which are collectively referred to as "high-level
waste."

     The joint owners of the Seabrook Project, through their managing agent
NAESCO, entered into contracts with the DOE for high-level waste disposal in
accordance with the NWPA. Under these contracts and the NWPA, the DOE was
required to take title to and dispose of the Seabrook Project's high-level waste
beginning no later than January 31, 1998. The DOE has not met its contractual
and statutory requirements under the NWPA calling for the DOE to begin accepting
spent fuel from the industry by January 1998. The DOE announced that its first
high-level waste repository will not be in operation until 2010 at the earliest.

     As a result of this delay, many states and nuclear plant operators,
including NAESCO, sued the DOE for injunctive relief and monetary damages. Two
U.S. Courts of Appeals ordered the DOE to proceed with its high-level waste
disposal obligations and ruled that plant operators are entitled to monetary
damages from DOE. However, there can be no assurance that the Seabrook Project
will collect damages from the DOE because, among other things, NAESCO's case
against the DOE is still pending. Until the DOE begins receiving nuclear waste
materials in accordance with the NWPA and its contracts, nuclear plants such as
Seabrook must retain high-level waste on-site or make other storage provisions.
NAESCO has advised the Company that the Seabrook Project has adequate on-site
storage capacity for high-level waste until approximately 2008

     In May 2001, the DOE issued a supplement to the 1999 draft Environmental
Impact Statement of Yucca Mountain in Nevada, and public hearings on this
document were held in the May-June 2001 period. On February 14, 2002, the DOE
recommended to President Bush that Yucca Mountain in Nevada be developed as the
nation's first long-term geologic repository for the disposal of spent nuclear
fuel and high-level nuclear

waste. On February 15, 2002 the President notified Congress that he considers
Yucca Mountain qualified for a construction permit application, taking the next
step in a series of steps required for approving the site as a nuclear materials
repository.

     The Low-Level Radioactive Waste Policy Act of 1980 requires each state to
provide disposal facilities for low-level waste ("LLW") generated within the
state, either by constructing and operating facilities or by joining regional
compacts with other states to jointly fulfill their responsibilities. However,
the Low-Level Radioactive Waste Policy Amendments Act of 1985 permits each state
in which a currently operating disposal facility is located (South Carolina,
Nevada and Washington) to impose volume limits and a surcharge on shipments of
LLW from states that are not members of their regional compact.

     The Seabrook Project ships certain LLW to privately owned facilities in
South Carolina and Utah. Since 1999, the Project has been shipping LLW to a
processing facility in Tennessee where the material is subjected to separation
and volume reduction methods to minimize the final volume to be disposed at a
burial site. All LLW generated by the Seabrook Project that exceeds the maximum
radioactivity level of LLW accepted by these facilities is currently stored
on-site at the Seabrook facility. LLW from normal Seabrook Project operations
will continue to be generated at a slow rate as a result of aggressive efforts
at the Seabrook Project to minimize this material. NAESCO has advised the
Company that the Seabrook Project's capacity for on-site storage of LLW is
expected to be sufficient to meet the project's storage requirements through
2006.

B.  FEDERAL DEPARTMENT OF ENERGY DECONTAMINATION AND DECOMMISSIONING ASSESSMENT

     Title XI of the Energy Policy Act of 1992 (the "Policy Act") provides for
decontaminating and decommissioning of the Federal DOE's enrichment facilities
to be partially funded by a special assessment against domestic utilities. Each
utility's share of the assessment is to be based on its cumulative consumption
of DOE enrichment services. As of December 31, 2001, the Company had accrued its
pro rata estimated obligation of $482,000 related to the project's prior years'
usage to be paid over the 15-year period beginning October 1, 1992.

C.  PRICE ANDERSON ACT

     In accordance with the Price Anderson Act, the limit of liability for a
nuclear-related accident is approximately $9.5 billion, effective November 18,
1994. The primary layer of insurance for this liability is $200 million of
coverage provided by the commercial insurance market. The secondary coverage is
approximately $9.3 billion, based on the 106 nuclear units (103 operating units
and three units that still handle used fuel) in the United States. The secondary
layer is based on a retrospective premium assessment of $88.1 million per
nuclear accident per licensed reactor, payable at a rate not exceeding $10
million per year per reactor. In addition, the retrospective premium is subject
to inflation based indexing at five year intervals and, if the sum of all public
liability claims and legal costs arising from any nuclear accident exceeds the
maximum amount of financial protection available, then each licensee can be
assessed an additional 5% ($4.4 million) of the maximum retrospective
assessment. With respect to the Seabrook Project, Great Bay and Little Bay would
be obligated to pay their ownership share of any assessment resulting from a
nuclear incident at any United States nuclear generating facility. Great Bay and
Little Bay estimate their maximum liability per incident currently would be an
aggregate amount of approximately $13.2 million per accident, with a maximum
annual assessment of about $1.5 million per incident, per year.

     The Seabrook Joint Owners are subject to retroactive assessments if losses
under those policies exceed the accumulated funds available to the insurer. The
maximum potential assessments against the Joint Owners with respect to losses
arising during the current policy year for the primary property insurance
program and the excess property damage policies are approximately $8.2 million
and $10.2 million, respectively. The Company's combined 15% share is $1.2
million and $1.5 million, respectively.

D.  NUCLEAR INSURANCE

     Insurance has been purchased by the Seabrook Project from Nuclear Electric
Insurance Limited ("NEIL") to cover the costs of property damage,
decontamination or premature decommissioning resulting from a nuclear incident
and American Nuclear Insurance/Mutual Atomic Energy Liability Underwriters
("ANI") to cover workers' claims. All companies insured with NEIL and ANI are
subject to retroactive assessments, if losses exceed the accumulated funds
available to NEIL and ANI, respectively. The maximum potential assessment
against the Seabrook Project with respect to losses arising during the current
policy years are $10.9 million. The Company's liability for the retrospective
premium adjustment for any policy year ceases six years after the end of that
policy year unless prior demand has been made.

     Great Bay and Little Bay also independently purchase business interruption
insurance from Nuclear Electric Insurance Limited ("NEIL"). The current policy
is in effect from April 1, 2001 until April 1, 2002 and a renewal policy has
been signed which will be in effect from April 1, 2002 until April 1, 2003. The
policy provides for the payment of a fixed weekly loss amount of $600,000 in the
event of an outage at the Seabrook Project of more than 23 weeks resulting from
property damage occurring from a "sudden fortuitous event, which happens by
chance, is unexpected and unforeseeable." The maximum amount payable to Great
Bay and Little Bay is a total of $81.1 million. Under the terms of the policy,
Great Bay and Little Bay are subject to a potential retrospective premium
adjustment of up to approximately $789,000 should NEIL's board of directors deem
that additional funds are necessary to preserve the financial integrity of NEIL.
Since NEIL was founded in 1980, there has been no retrospective premium
adjustment; however, there can be no assurance that NEIL will not make
retrospective adjustments in the future. The liability for this retrospective
premium adjustment ceases six years after the end of the policy unless prior
demand has been made.

     The board and management of NEIL has announced, that in light of the events
of September 11, 2001, the current coverage for terrorism will remain available
under all the NEIL policies, but with the addition of a provision regarding the
maximum recoveries available for multiple terrorism occurrences. The NEIL board
approved the following changes to the NEIL policy forms to respond to the
increased potential of multiple terrorism losses at insured sites: (1) increase
the multiple for the maximum retrospective premium adjustments from five to ten;
and (2) provide specifically for the use of NEIL resources for multiple losses
resulting from terrorism within one year. Under this provision, all losses
occurring within 12 months from the date of the first loss would share a single
recovery of $3.24 billion plus any amounts NEIL recovers from reinsurers or the
government, with priority for the property claims over accidental outage claims.

     Valuation allowances have been provided against any deferred tax assets,
net due to the limitations on the use of carryforwards, discussed below, and the
uncertainty associated with future taxable income. The valuation allowance of
$56,086,000 as of December 31, 1994, if subsequently recognized, will be
allocated directly to paid in capital.

     For federal income tax purposes, as of December 31, 2001, the Company had
net operating loss carry forwards ("NOLs") of approximately $208 million, which
are scheduled to expire between 2004 and 2019. Because the Company has
experienced one or more ownership changes, within the meaning of Section 382 of
the Internal Revenue Code of 1986, as amended, an annual limitation is imposed
on the ability of the Company to use $115 million of these carryforwards. The
Company's best estimate at this time is that the annual limitation on the use of
$115 million of the Company's NOLs is approximately $5.5 million per year. Any
unused portion of the $5.5 million annual limitation applicable to the Company's
restricted NOLs is available for use in future years until such NOLs are
scheduled to expire. The Company's other $93 million of NOLs are not currently
subject to such limitations.

4.  CAPITAL EXPENDITURES

     The Company's cash capital expenditures, including nuclear fuel, are
estimated to be approximately $5.3 million in 2002.

5.  ENERGY MARKETING

     The Company utilized unit contingent and firm forward sales contracts to
maximize the value of its 174 MW power supply from the Seabrook Project. The
Company had not entered into any forward firm energy trading contracts as of
December 31, 2001, nor does it expect to in 2002, in light of its expected sale
of its ownership interest in the Seabrook Project in 2002. As a result, as of
December 31, 2001, the Company had no unrealized loss or gain on the
mark-to-market of forward firm energy trading contracts recorded in accrued
expenses. The net change in unrealized gain on trading activities for the year
ended December 31, 2001 was $12,879,000 and is included in the accompanying
consolidated statement of income for 2001. As of December 31, 2000, the Company
had a net unrealized loss of approximately $12,879,000 recorded in accrued
expenses. The net change in unrealized loss on trading activities for the year
ended December 31, 2000 was $12,232,000 and is included in the accompanying
consolidated statement of income for 2000.

6.  PURCHASED POWER AGREEMENTS

     Great Bay is party to a purchased power agreement, dated as of April 1,
1993 (the "UNITIL Purchased Power Agreement"), with UNITIL Power Corporation
("UNITIL") that provides for Great Bay to sell to UNITIL 0.8696% of the energy
and capacity of Seabrook, approximately 10 MW. The UNITIL Purchased Power
Agreement commenced on May 1, 1993 and runs through October 31, 2010. The
current price of power under the UNITIL Purchased Power Agreement is 5.38 cents
per kilowatt-hour ("kWh"). The price is subject to increase in accordance with a
formula that provides for adjustments at less than the actual rate of inflation.
UNITIL has an option to extend the UNITIL Purchased Power Agreement for an
additional 12 years until 2022.

     The UNITIL Purchased Power Agreement was front-end loaded whereby UNITIL
paid higher prices, on an inflation-adjusted basis, in the early years of the
Agreement and lower prices in later years. The amount of the excess paid by
UNITIL in the early years of the UNITIL Purchased Power Agreement was quantified
in a "Balance Account" which increased annually to a total of $4.1 million in
July 1998, and then decreased annually, reaching zero in July 2001. If the
UNITIL Purchased Power Agreement had terminated prior to its scheduled
termination, and if at that time there was a positive amount in the Balance
Account, Great Bay would have been obligated to refund that amount to UNITIL
Power. To secure the obligation of Great Bay to repay UNITIL the amount in the
Balance Account, the UNITIL Purchased Power Agreement granted UNITIL a "Second
Mortgage" on Great Bay's interest in the Seabrook Project. As a result of the
Balance Account reaching zero in July 2001, the Second Mortgage was discharged
by UNITIL in August 2001.

     To secure the obligation of Great Bay under the UNITIL Purchased Power
Agreement to pay damages in the event of a default by Great Bay, the UNITIL
Purchased Power Agreement grants UNITIL a "Third Mortgage" on Great Bay's
interest in the Seabrook Project. The Third Mortgage is subject and subordinate
to (i) senior mortgages and security agreements securing Great Bay's
indebtedness to lenders in an aggregate amount not to exceed $80,000,000 and
(ii) other mortgages that may be granted by Great Bay to other purchasers of
power from Great Bay to secure a Balance Account or similar obligation. The
UNITIL Purchased Power Agreement further provides that UNITIL's Third Mortgage
will rank pari passu with other mortgages that may be granted by Great Bay to
other purchasers of power from Great Bay to secure potential payment of damages
or similar obligations.

     Great Bay originally entered into a power sales agreement, dated as of
November 19, 1999, with Little Bay. Great Bay and Little Bay renewed this
agreement on November 19, 2001 for a one-year term ending

                                       F-20

November 19, 2002. Under the terms of the agreement, Little Bay sells at cost,
and Great Bay purchases, all of the output of the portion of Seabrook owned by
Little Bay. This agreement is a unit power sale agreement. Accordingly, when all
or part of Little Bay's interest in Seabrook is not producing, the obligation of
Little Bay to sell (and of Great Bay to purchase) is proportionately eliminated.
The agreement can be terminated at any time by mutual consent of the parties,
after any notice required by law.

     In February 2001, Great Bay executed a Purchase Power Agreement with Select
Energy ("Select") whereby Great Bay sold 50 MWs of energy associated with the
Seabrook Project to Select in exchange for 25 MWs of energy associated with
Millstone Unit 2 and 25 MWs of energy associated with Millstone Unit 3.
Millstone is a nuclear power plant located in Connecticut. The term of this
agreement was April 1, 2001 through December 31, 2001. Delivery of power from
either company was contingent on each of the units operating at a certain
capacity.

     As part of the agreement, Select made a prepayment of $3.7 million to Great
Bay in February 2001 and a second prepayment of $3.3 million in March 2001.
Great Bay compensated Select for the prepayments by (i) paying 12% annual
interest for the period from February 6, 2001 through March 31, 2001 and (ii)
giving Select a price differential for the power being exchanged until such time
as the Select prepayment had been repaid. In order to collateralize the
transaction, Great Bay and Little Bay each provided Select with a mortgage lien
and security interest in their respective interests in the Seabrook Project.
Great Bay repaid Select in 2001 and the mortgage liens and security interests
were released as of July 2001 and there was no price differential in exchanging
power throughout the remaining term of the agreement.

7.  STOCK OPTION PLAN

     On April 24, 1995, the Board of Directors of the Company established the
1995 Stock Option Plan (the "1996 Plan"), which received shareholder approval at
the Company's annual meeting on April 16, 1996. On May 2, 2001 the Board of
Directors of the Company established the 2001 Non-Statutory Stock Option Plan
(the "2001 Plan"). The 2001 Plan will be presented for shareholder approval at
the Company's annual meeting on April 24, 2002. The purpose of these plans is to
secure for the Company and its shareholders the benefits arising from capital
stock ownership by employees, officers and directors of, and consultants or
advisors to, the Company who are expected to contribute to the Company's future
growth and success. Options granted pursuant to the 1996 Plan may be either
incentive stock options meeting the requirements of Section 422 of the Internal
Revenue Code or nonstatutory options, which are not intended to meet the
requirements of Section 422. Options granted pursuant to the 2001 plan will be
non-statutory options that are not intended to meet the requirements of Section
422 of the Internal Revenue Code. The 1996 Plan and the 2001 Plan are
administered by the Board of Directors of the Company and may be modified or
amended by the Board in any respect, subject to shareholder approval in certain
instances.

     The Company accounts for the plans under APB Opinion No. 25, and as such no
compensation cost has been recognized as the options are granted at Fair Market
Value.

     On December 3, 1998, the Board of Directors of the Company voted to reprice
all of the outstanding options of the Company, at that date, as the then
outstanding options were "out of the money." The Board of Directors determined
that the then outstanding options no longer had the desired motivational effect
or compensatory benefit for the employees. The repricing of the options was
based on the current market value of the stock as of December 18, 1998.
Simultaneously with the repricing, 139,583 existing options were forfeited.

     FASB Interpretation No. 44, Accounting for Certain Transactions involving
Stock Compensation("FIN 44"), effective July 1, 2000 and applied prospectively,
(except for direct or indirect option repricings and the definition of an
employee in which case the effective date is December 15, 1998), addresses
compensation issues regarding the definition of an employee, modifications to
plan awards, changes in grantee status, business combinations and share
repurchase features. For transactions subject to the December 15, 1998

                                       F-21
<PAGE>

effective date, no compensation expense is recognized for the period between
December 15, 1998 and July 1, 2000. FIN 44 requires variable accounting when
direct or indirect reductions of the exercise price occur. During 2000, the
Board of Directors of the Company accelerated the vesting period of the options
held by certain employees of the Company. In accordance with FIN 44, the Company
recorded the expense related to the repriced and the accelerated options with
the total credit of $105,000 being recorded in equity. No additional
compensation expense was required during 2001 for these options.

     Had compensation cost for these Plans been determined consistent with SFAS
No. 123, Accounting for Stock Based Compensation, the Company's net income and
earnings per share would have been reduced to the following pro forma amounts.

9.  NEW ACCOUNTING PRONOUNCEMENTS

     In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." SFAS No. 133 establishes accounting and
reporting standards requiring that every derivative instrument (including
certain derivative instruments embedded in other contracts) be recorded on the
balance sheet as either an asset or liability measured at its fair value. SFAS
No. 133 requires that changes in the derivative's fair value be recognized
currently in earnings unless specific hedge accounting criteria are met. Special
accounting for qualifying hedges allows a derivative's gains and losses to
offset related results on the hedged item in the income statement, and requires
that a company must formally document, designate and assess the effectiveness of
transactions that receive hedge accounting.

     SFAS No. 133, as amended by SFAS No. 137, was effective for all fiscal
quarters of all fiscal years beginning after June 15, 2000. SFAS No. 133 must be
applied to (a) derivative instruments and (b) certain derivative instruments
embedded in hybrid contracts that were issued, acquired or substantively
modified after December 31, 1997 (and, at the company's election, before January
1, 1998).

     The Company completed its review and implementation of SFAS No. 133,
effective January 1, 2001. The Company has taken an inventory of its contracts
and identified the forward sale and purchase contracts that were marked to
market in accordance with EITF 98-10, as derivatives under SFAS No. 133. The
Company did not identify any other contracts to be derivatives under SFAS No.
133. The Company will continue to mark to market its forward sale and purchase
contracts in accordance with EITF 98-10 and EITF 00-17 and thus the adoption of
SFAS No.133 did not have an impact on the Company's financial position or
results of operations.

     Additional new Statements of Financial Accounting Standards were approved
and issued by the FASB in 2001. These statements are described in Footnotes 1(H)
and 1(T) of the financial statements.

10.  PROPERTY TAXES

     For each of the tax years 1994, 1995, 1996, 1997 and 1998, Great Bay filed
property tax abatement applications with the towns of Hampton and Hampton Falls.
The abatement requests were denied. Great Bay filed appeals for each of those
years with the New Hampshire Board of Tax and Land Appeals (the "BTLA"). On
November 11, 1999, Great Bay reached agreements settling the property tax
litigation. As a result of the settlement agreement, Great Bay received $146,450
from the Town of Hampton and $21,967 from the Town of Hampton Falls. With regard
to Hampton Falls, the settlement established an assessed valuation of $7,000,000
for 1999 and $2,500,000 for 2000. With regard to the Town of Hampton, the
settlement established an assessed valuation of $20,000,000 for 1999 and
$15,000,000 for 2000. On November 19, 2001, Great Bay approved an Addendum to
the Settlement Agreement dated November 11, 1999. This addendum extended the
property tax settlement agreements through December 2002. With regard to Hampton
Falls, the addendum established an assessed valuation of $3,000,000 for 2001 and
$2,500,000 for 2002. With regard to the Town of Hampton, the settlement
established an assessed valuation of $17,000,000 for 2001 and $16,000,000 for
2002.

11.  COMMITMENTS AND CONTINGENCIES

     BayCorp and its wholly owned subsidiaries currently lease office space
under noncancelable operating leases. Rental expense under operating lease
agreements for the years ended December 31, 2001 and 2000 was $101,325 and
$78,747, respectively.

12.  INVESTMENTS IN UNCONSOLIDATED AFFILIATES

     As of December 31, 1999, the Company owned 100% of HoustonStreet.
HoustonStreet raised additional equity in 2000 from outside investors and as a
result, as of December 4, 2000, the Company's ownership fell below 50%, to
45.9%. Subsequently, the Company deconsolidated HoustonStreet as of December 4,
2000, started accounting for this investment on the equity method and suspended
recognition of additional HoustonStreet losses as of that date. Prior year
financial statements are presented in conformance with the equity method of
accounting. Prior to the deconsolidation, the Company recognized its share of
the losses of HoustonStreet in the consolidated financial statements. Summarized
financial information for the Company's investment in HoustonStreet, as
accounted for by the equity method, is as follows:

                             LETTER TO SHAREHOLDERS

     This past year was a volatile time for the nation and it seemed especially
so for companies in the energy business. From the sudden collapse of Enron to
increased security at nuclear plants resulting from the tragic events of
September 11th, BayCorp was directly affected by the turmoil in the energy
sector. This volatility carried over to the stock prices of many energy
companies. While a number of energy company stocks, particularly those of
independent power producers and energy trading companies, were down 30% to 50%
or more, BayCorp's stock price held up well. BayCorp's stock price finished the
year at $9.40 per share, up 42% for the year. This represents a solid
performance in a difficult environment, particularly when compared to the
overall stock market and other independent power producer and energy stocks.

     BayCorp started 2001 in a tenuous cash position. Seabrook was in the middle
of what was ultimately to be a 100 day refueling outage, extended by nearly 70
days due to damage to one of the plant's emergency diesel generators. Due to the
extended shutdown, BayCorp needed to secure bridge financing to meet its
Seabrook payment obligations for the months of February and March 2001. Once
Seabrook returned to service, however, BayCorp was able to replenish its
depleted cash reserves, repay the bridge financing in its entirety and
significantly improve the Company's financial position. To show just how
dramatic the improvement was, on December 31, 2000 BayCorp had working capital
(current assets less current liabilities) of $283,000 and a current ratio of
1.0, whereas on December 31, 2001 the Company's working capital had increased to
$22,636,000 and its current ratio was 4.3.

SEABROOK OPERATIONS

     As I have explained in previous shareholder letters, since most of the
Seabrook costs are fixed, the economics of the Seabrook plant are driven largely
by two factors: (1) capacity factor and (2) New England wholesale power prices.
Capacity factor is the actual plant output divided by the output that would be
achieved if the plant operated at its maximum capacity throughout the period.
Since no refueling outage had been planned for 2001, we had expected a high
capacity factor. Due to the extended refueling outage, however, Seabrook did not
return to operation until February 1, 2001. For the full year, Seabrook operated
at a capacity factor of 85.8%. From February 1 through the remainder of 2001,
Seabrook operated at a very respectable 93.3% capacity factor.

     The tragic events of September 11th have resulted in changes to the way
Seabrook and other nuclear plants are being protected. Already some of the most
secure industrial facilities in the country, nuclear plants have made a number
of changes in response to the new threats that face our nation. While the NRC
continues to examine the issue, we do know that securing Seabrook against this
threat will result in increased operating and capital costs for the foreseeable
future.

     Wholesale power prices steadily declined throughout 2001. For example, the
average NEPOOL energy clearing price for the month of January 2001 was $62.57
per megawatt hour. In December 2001, however, the average clearing price had
fallen to $27.18 per megawatt hour. Fortunately, Great Bay sold a fair amount of
its 2001 Seabrook entitlement forward during a period of higher power prices to
hedge against price volatility and thus achieved a 12% increase in its average
sales price for energy and capacity in 2001. Great Bay's average sales price in
2001 was $42.85 per megawatt hour as compared to $38.74 per megawatt hour in
2000. Great Bay's short-term sales price was 5% higher than the NEPOOL energy
clearing price in 2001 during times of Seabrook operation, resulting in
additional net income to shareholders of $2.4 million, or approximately $0.28
per share in 2001. This strategy of actively managing our Seabrook entitlement
created value for shareholders as compared to a strategy of simply taking the
market clearing price from NEPOOL.

     As discussed below, the Seabrook auction process is now well underway. It
appears likely that BayCorp will sell its interest in Seabrook later this year.
In a continued effort to hedge against price volatility, we decided to sell
forward all of our Seabrook entitlement through September 2002. We were able to
make these sales at an average price of $40.59 per megawatt hour and on a unit
contingent basis (as opposed to a firm
<PAGE>

sale), so we do not assume any replacement power risk in the event of a
scheduled or unscheduled outage at Seabrook. After we made our forward sales,
wholesale power prices continued to decline such that this average sales price
through September 2002 is well above current market prices and secures positive
cash flow of approximately $5.3 million through September, assuming a 40 day
refueling outage and a 92% capacity factor during non-refueling periods at
Seabrook. Seabrook's next refueling is scheduled to start on May 4, 2002.

     It is impossible to reflect on the energy sector in 2001 without mentioning
Enron. Unfortunately, BayCorp was not immune from the effects of Enron's
collapse. In January, we announced that Enron terminated its power purchase
contracts with Great Bay which provided for purchases of power by Enron through
December 31, 2001. Fortunately, we have no contracts with Enron for periods
beyond December 31, 2001. Enron owes approximately $1.1 million to Great Bay for
power delivered prior to Enron's Chapter 11 bankruptcy filing on December 2,
2001. Great Bay also had an administrative claim of approximately $684,000 for
power delivered after Enron's bankruptcy filing and prior to the termination of
the contracts, which Enron paid in February 2002. We took a charge to earnings
in the fourth quarter of 2001 of approximately $1.1 million, or $0.13 cents per
share, to establish a reserve for doubtful accounts due to the current
uncertainty of collecting the remaining amounts owed by Enron to Great Bay. Any
recovery on our claim as part of Enron's Chapter 11 case would represent a
one-time non-recurring gain for BayCorp.

SEABROOK AUCTION

     As part of deregulation legislation in Connecticut and New Hampshire,
Northeast Utilities ("NU"), the operator and largest owner of Seabrook, is
required to sell its ownership interests in Seabrook by December 31, 2003. In
October 2000, BayCorp announced that it had reached an agreement with NU to join
with NU in the sale of BayCorp's 15% ownership interest in Seabrook. By
combining to sell our share with NU and several other owners, the ultimate
purchaser will be able to acquire an 88% ownership interest in the plant. We
believe this will result in the best possible price for BayCorp's share of
Seabrook. The auction process began in earnest in September 2001 with the
selection of J.P. Morgan as the sale manager for the auction. We anticipate the
selection of the winning bidder in the second quarter of 2002 and expect the
closing to occur by the end of the year.

     Under the terms of our agreement with NU, BayCorp will receive the sales
price established by the auction process. In the event that the sale yields
proceeds for BayCorp of more than $87.2 million, BayCorp and NU will share the
excess proceeds. Should BayCorp's sales proceeds be less than $87.2 million, NU
will make up the difference below that amount on a dollar for dollar basis up to
a maximum of $17.4 million. Under the agreement, BayCorp will be paid separately
for nuclear fuel and inventory, which we expect will yield between $10 million
and $14 million in cash to BayCorp. The agreement also limits any top-off amount
required to be funded by BayCorp for decommissioning as part of the sale process
at the amount required by Nuclear Regulatory Commission regulations. As part of
the sale, we anticipate that BayCorp will transfer virtually all of its
liabilities, including the decommissioning liability, and retain all of its cash
in addition to the proceeds from the auction.

HOUSTONSTREET

     HoustonStreet was right in the middle of the dotcom boom and bust. Just as
investors uncritically bid up the values of anything remotely Internet-related,
they were equally indiscriminate on the way down. Many of HoustonStreet's
competitors did not survive this shakeout. We continue to believe that
HoustonStreet represents a business model that makes sense and leverages the
strengths of the Internet - bringing a network of individuals from disparate
geographic locations together to conduct business and exchange information at a
very low cost. In order to survive, however, HoustonStreet was forced to
undertake a painful restructuring and cost-cutting effort. HoustonStreet ceased
its power, natural gas and European operations and focused exclusively on its
platforms for trading domestic crude oil and refined products, such as gasoline,
heating oil and jet fuel.

     HoustonStreet was betting a large part of its future growth on its
strategic agreement with EnronOnline, whereby North American electricity and
natural gas prices posted on EnronOnline would have been automatically posted on
HoustonStreet. HoustonStreet believes it satisfied its obligations under its
agreement with Enron, but Enron elected to terminate the agreement in May 2001.
HoustonStreet invoked the
<PAGE>

arbitration clause for settling disputes in its contract with Enron, but that
claim has been stayed by Enron's Chapter 11 filing and any recovery is highly
uncertain.

     The good news is that HoustonStreet has stabilized operations and is
steadily gaining new customers and marketshare. HoustonStreet is a recognized
leader in online trading of crude oil and refined products, with an estimated
10-15% share of the overall domestic physical OTC market for these products. It
is back-to-basics for HoustonStreet, with a zealous focus on its customers and
costs. While it is impossible to predict how this market will unfold,
HoustonStreet remains focused on those things within its ability to influence
and control in its effort to build a profitable, sustainable business.

CONCLUSION

     As I mentioned in last year's Letter to Shareholders, since it now appears
likely that we will sell our Seabrook asset later this year, an important
question for shareholders remains, "what will you do with the cash?" The answer
is simple - management and the Board of Directors are examining all of our
options and will do whatever we believe provides the greatest return to
shareholders. We are continuing to look for attractive energy-related
investments, but if no such investments can be identified, we will return cash
to shareholders in the most tax-efficient manner possible. We operate under the
principle that if we can't find opportunities to invest your money that provide
attractive returns, we will return it to you. I expect the Board to make a final
decision later this year after the winning bidder for Seabrook has been
announced and all reasonable alternatives have been fully explored. We will
communicate to shareholders the Company's plan as soon as that decision has been
made.

     Thank you for your continued support of BayCorp. I also want to thank the
dedicated employees of BayCorp, HoustonStreet and Great Bay. As our business and
the energy industry continue to evolve and change, it is the dedication,
perseverance and creativity exhibited by our employees that remains constant. It
is something for which we should all be proud and thankful.
