Explanatory Note

This Form 10-Q/A amends BayCorp Holdings, Ltd.'s quarterly report on Form 10-Q
for the quarter ended September 30, 2002 filed on October 28, 2002 and is being
filed to reflect amendments disclosed in the Company's Form 10-K/A for the
period ended December 31, 2001 filed January 30, 2003. The September 30, 2002
Form 10-Q is amended to (i) reflect an increase in paid in capital and an
increase in accumulated deficit of approximately $6.7 million as a result of the
change in 2000 in the value of the Company's investment in HoustonStreet
Exchange, Inc. ("HoustonStreet"); this increase in the Company's investment in
HoustonStreet increased the Company's 2000 loss by approximately $6.7 million,
(ii) reflect an increase in accumulated deficit of approximately $211,000 for a
net increase in 2001 and 2000 general and administrative expenses including
compensation costs related to repriced and accelerated options, (iii) an
increase in accumulated deficit of $225,000 based on actual taxes incurred in
2001, and (iv) reclassify decommissioning accretion and decommissioning interest
on the Consolidated Statements of Income from Other Income/Deductions to
Operating Expenses for all periods presented. These restatements are all
non-cash adjustments to the Company's financial statements. This report speaks
as of the original filing date and, except as indicated, has not been updated to
reflect events occurring subsequent to the original filing date.

                          NOTES TO FINANCIAL STATEMENTS

NOTE 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 sell wholesale electricity, Great Bay Power Corporation ("Great
Bay") and Little Bay Power Corporation ("Little Bay"), each of which is
wholly-owned as of September 30, 2002. In addition, BayCorp owns 46.4% of
HoustonStreet Exchange, Inc. ("HoustonStreet"), an Internet-based independent
crude oil and refined products trading exchange.

         Great Bay and Little Bay generate and sell wholesale electricity. 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. HoustonStreet, an equity
investment of BayCorp, developed and operates HoustonStreet.com.

         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.


                                       7
<PAGE>
                             BAYCORP HOLDINGS, LTD.

         On April 15, 2002, the Company announced that BayCorp and other selling
owners reached an agreement with FPL Group, Inc. ("FPL Group") for the sale of
approximately 88% of the Seabrook Project. The purchase price for the entire
88.2% interest is $836.6 million, subject to certain adjustments at closing.
Under the terms of the purchase and sale agreement and BayCorp's agreement with
NU, Baycorp expects to receive approximately $113 million for its 15% ownership
interest in Seabrook, nuclear fuel and inventory. This amount assumes a November
1, 2002 closing and is based upon expected balances for nuclear fuel and
inventory and other purchase price adjustments. This amount is net of the
sharing of proceeds with NU under the October 2000 agreement and also net of any
top-off amount required to fund BayCorp's share of the Seabrook decommissioning
liability. Under the terms of the agreement with FPL Group, BayCorp and the
other selling owners are required to top-off the decommissioning trust fund to
ensure that the decommissioning fund balance is sufficient to satisfy the
requirements of the New Hampshire Decommissioning Financing Committee ("NDFC")
at the time of closing. The decommissioning top off and the amount received for
nuclear fuel and inventory are subject to adjustment to reflect actual values at
the time of closing.

         In August 2002, BayCorp announced that it had reached agreement with
Unitil Power Corporation ("Unitil") to amend a long-term electric power sales
agreement between Unitil and Great Bay. The original agreement provided for the
sale of 10 megawatts of Great Bay's Seabrook entitlement to Unitil on a
unit-contingent basis at a price of $53.84 per MWh (subject to escalation if
inflation rises above 4%) through October 2010. Under the amended agreement,
Great Bay will supply Unitil with 9.06 MW of firm power (as opposed to Seabrook
unit-contingent power) at a price of $50.34 per MWh with the same escalation
provisions and term. The amendment also provides alternative security for
Unitil's benefit, to replace and discharge the mortgage on Great Bay's Seabrook
interest that currently secures Great Bay's performance of the agreement.

         The amendment received Federal Energy Regulatory Commission ("FERC")
approval in August 2002. Great Bay has notified Unitil that the amended
agreement will be effective on November 1, 2002. The amended Unitil contract
will not be sold in the asset sale, and following the closing will constitute
the only significant non-liquid asset retained by either Great Bay or Little
Bay.

NOTE B - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         The unaudited financial statements included herein have been prepared
on behalf of the Company pursuant to the rules and regulations of the Securities
and Exchange Commission ("SEC") and include, in the opinion of management, all
adjustments, consisting of normal recurring adjustments, necessary for a fair
presentation of interim period results. Certain information and footnote
disclosures normally included in financial statements prepared in accordance
with generally accepted accounting principles have been omitted or condensed
pursuant to such rules and regulations. The Company believes, however, its
disclosures herein, when read in conjunction with the Company's audited
financial statements for the year ended December 31, 2001 as filed in Form
10-K/A, are adequate to make the information presented not misleading. The
Company's significant accounting policies are described in Note 1 of Notes to
Consolidated Financial Statements included in the Company's 10-K/A. The results
for the interim periods are not necessarily indicative of the results to be
expected for the full fiscal year.

         Previously, Great Bay utilized unit contingent and firm forward power
sales contracts to maximize the value of its 174 MW power supply from the
Seabrook Project. The Company follows the


                                       8

                             BAYCORP HOLDINGS, LTD.

provisions of SFAS 133 Accounting for Derivative Activities and Hedging
Activities. The Company recorded the related firm forward power sale contracts
at fair value based on the estimated contract replacement value at each balance
sheet date. The Company had no firm forward power sales contracts as of
September 30, 2002 that required mark-to-market accounting treatment. As a
result, as of September 30, 2002, the Company had no unrealized loss or gain on
the mark-to-market of firm forward power sales contracts recorded in accrued
expenses. The net change in unrealized gain/loss on firm forward power sales
contracts included in the accompanying consolidated statements of income for the
quarters ended September 30, 2002 and September 30, 2001 was $0 and a gain of
approximately $1,316,000, respectively, and for the nine months ended September
30, 2002 and September 30, 2001 was $0 and a gain of approximately $14,636,000,
respectively. The Company's amended power sale agreement with Unitil, as
discussed previously, will require mark-to-market treatment when it becomes
effective. The Company expects the agreement to become effective on or about
November 1, 2002.

         Certain amounts in prior periods have been reclassified to conform with
current period presentation. Decommissioning cost accretion and decommissioning
trust fund income are currently being presented as a component of operating
expenses.

NOTE C - COMMITMENTS AND CONTINGENCIES

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 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."

Utility Deregulation; Public Controversy Concerning Nuclear Power Plants


                                       9

                             BAYCORP HOLDINGS, LTD.

         The NHPUC and the regulatory authorities with jurisdiction over
utilities in New Hampshire and state legislatures of several other states in
which Great Bay and Little Bay sell electricity are considering or are
implementing initiatives relating to the deregulation of the electric utility
industry. Simultaneously with the deregulation initiatives occurring in each of
the New England states, the New England Power Pool ("NEPOOL") restructured to
create and maintain open, non-discriminatory, competitive, unbundled markets for
energy, capacity, and ancillary services. All of the deregulation initiatives
open electricity markets to competition in the affected states. While Great Bay
and Little Bay believe they are low-cost producers of electricity and will
benefit from the deregulation of the electric industry, it is not possible to
predict the impact of these various initiatives on the companies.

         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 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. Should the proposed transaction for the sale of Seabrook be completed,
the Company would no longer be subject to these contingent liabilities.

Decommissioning Liability

         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 at
the date Little Bay acquired its interest in Seabrook.

         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 NDFC. The current estimated cost to decommission the
Seabrook Project (based on a determination made by the NDFC in Docket 2001-1) is
approximately $555.6 million in 2001 dollars, assuming for decommissioning
purposes, a remaining 25-year life for the facility and a future cost escalation
of 5.25% per year. The Company's pro-rata share of this estimated cost of
decommissioning as of September 30, 2002 was approximately $89.2 million.

         The Staff of the 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


                                       10

                             BAYCORP HOLDINGS, LTD.

these questions, the FASB agreed to review the accounting for nuclear
decommissioning costs and, as a result, 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 initial FASB exposure draft. 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. The new statement is effective for
the Company on January 1, 2003. The Company does not expect the adoption of SFAS
143 to have a material impact on its Balance Sheet or reported results of
operations because of the pending sale of Seabrook.

         Great Bay and Little Bay, consistent with industry practice, 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
September 30, 2002, 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 5.25%, over the funding
period, to September 30, 2002, represented a liability of approximately $89
million reflected in the accompanying balance sheet. 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 $1,231,000 and $816,000 for the three months ended September 30, 2002
and September 30, 2001, respectively and $3,694,000 and $2,446,000 for the nine
months ended September 30, 2002 and September 30, 2001, respectively. The change
in the accretion between years reflects adjustments to the estimated cost of
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 trusts are recorded as investments 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 loss of approximately $778,000 as of September 30, 2002.


                                       11

                             BAYCORP HOLDINGS, LTD.

         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. Under the terms of the proposed sale of
Seabrook, the Company would no longer be subject to this obligation.

         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 would
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, and as such,
periodic payments have not been required. 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
decommissioning expenses. As of September 30, 2002 the fair market value of the
Little Bay decommissioning account was approximately $13.6 million.

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

         Pursuant to New Hampshire law and the purchase and sale agreement for
the sale of the Company's Seabrook interest, Great Bay and Little Bay are
required to "top off" their decommissioning trust funds so that the fund balance
meets the funding requirements established by the NDFC in Docket 2001-01. The
balance of the Great Bay and Little Bay decommissioning trusts, which are
aggregated for this purpose, was approximately $32.3 million as of June 30, 2002
and as of that date was projected to be approximately $33 million at November
15, 2002, the then anticipated closing date of the asset sale, based upon the
anticipated required contributions to the fund between July 1, 2002 and November
15, 2002. The fund balance will fluctuate due to the market performance of the
fund, and the decommissioning top off and net proceeds will accordingly increase
or decrease. Based on that estimate, the Company estimates that its top off
payment will be approximately $7 million assuming a closing date for the sale of
Seabrook of November 1, 2002.

NOTE D - INVESTMENT IN HOUSTONSTREET

         As of December 31, 1999, the Company owned 100% of HoustonStreet.
During 2000, HoustonStreet raised additional equity from outside investors and
as a result the Company's ownership

fell below 50%. Subsequently, the Company wrote its investment in HoustonStreet
down to zero and suspended recognition of additional HoustonStreet losses. Prior
to the sale of a portion of its investment in HoustonStreet, 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:

         As of September 30, 2002, the Company had no investments or receivables
from HoustonStreet recognized on the accompanying balance sheet. The Company
suspended recognition of equity losses beginning in 2000 after its investment in
and receivables from HoustonStreet were written down to zero. The Company has no
obligations to further fund HoustonStreet.

NOTE E - EQUITY

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

         In March 2002, in connection with the exercise of stock options, the
Company received limited recourse promissory notes and stock pledge agreements
from its President, Frank Getman, and a director, John Tillinghast. Mr. Getman
was given two separate loans dated March 27, 2002, one for $167,502 and one for
$108,123. On March 7, 2002, Mr. Tillinghast was given a loan for $461,502. The
loans are secured by stock pledge agreements between the individuals and the
Company. The notes, which were approved by the Company's full board of
directors, bear interest at 5%. The notes and agreements were executed in order
to allow for the exercise of certain stock options before they expired. The
notes were given in lieu of cash payments for the exercise price of the options.
The total exercise price of these options was $737,127. Mr. Getman has pledged
56,250 shares under his agreements and Mr. Tillinghast has pledged 94,184 shares
under his agreement. The notes are due on the earlier of (i) December 31, 2003
or (ii) 30 days after the payment to Great Bay, Little Bay and BayCorp or its
common shareholders, as the case may be, of the proceeds of the sale of (a)
Great Bay's and Little Bay's interests in the Seabrook Project or (b) BayCorp
shares of capital stock of Great Bay and Little Bay or (c) the outstanding
shares of capital stock of BayCorp by merger, share exchange or otherwise. The
security agreements provide that the borrowers must maintain at least two times
the principal loan value in the

event of partial repayments. The Company has no agreements, formal or informal,
to forgive the loans or change the terms on the loans

         Upon maturity, the outstanding balance, and all accrued but unpaid
interest, shall be due and payable in full. The Company's current expectation is
that the Company's sale of its Seabrook asset will take place on November 1,
2002, with proceeds transferred at that time. The promissory notes issued to Mr.
Getman and Mr. Tillinghast will be repaid within 30 days of this closing, or on
or before December 1, 2002. The loans have been reflected in the accompanying
balance sheet as a reduction in equity as required by generally accepted
accounting principles. Compensation expense related to the exercise of these
stock options is measured based on the current market price of the Company's
common stock and the number of options exercised.

         Unrealized gains (losses) on securities held by the Company in its
decommissioning trust fund and short-term investment accounts are recorded as
Accumulated Other Comprehensive Income (Loss) in the Company's balance sheet.
Accumulated other comprehensive income (loss) and the current period charge are

NOTE F - NEW ACCOUNTING PRONOUNCEMENTS

         In August 2001, the FASB issued Statement of Financial Accounting
Standards No. 143, Accounting for Asset Retirement Obligations ("SFAS 143"),
effective for the Company's 2003 fiscal year, which provides guidance on
accounting for nuclear plant decommissioning costs. SFAS 143 prescribes fair
value accounting for asset retirement liabilities, including nuclear
decommissioning obligations, and requires recognition of such liabilities at the
time incurred. The sales agreement with NU established a minimum expected value
for the Company's investment in the Seabrook plant and the expected deal with
FPL Group established a fair value. 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. 143.

         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 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 was
effective beginning January 1, 2002. The initial adoption of SFAS No. 144 did
not have an impact on the Company's financial position or results of operations.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS.

                             BAYCORP HOLDINGS, LTD.

Overview

         BayCorp derives substantially all of its revenue through its energy
sales activities and its 100% equity interest in Great Bay and Little Bay. Great
Bay and Little Bay are electric generating companies whose principal asset is a
combined 15% joint ownership interest in the Seabrook Project.

         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: Third Quarter of 2002 Compared to the Third Quarter of
2001

Operating Revenues

         BayCorp's operating revenues decreased by approximately $6,800,000, or
30.4%, to $15,559,000 in the third quarter of 2002 as compared to $22,359,000 in
the third quarter of 2001. The decrease in operating revenues was primarily
attributable to lower sales volume from the resale of purchased power in the
third quarter of 2002 as compared to the sales volume from the resale of
purchased power in the third quarter of 2001. During the third quarter of 2001
the Company was obligated to sell power on a firm basis. Great Bay purchased
power for resale pursuant to a purchase power agreement to support its firm
power sale obligation. There were no significant purchases of power for resale
made during the third quarter of 2002. The Seabrook capacity factor for the
third quarter of 2002 was 100% as compared to 99.2% for the third quarter of
2001.

         During the three months ended September 30, 2002, Great Bay's average
selling price decreased 8.2%, to 4.05 cents per kilowatt hour ("kWh") as
compared to an average selling price of 4.41 cents per kWh for the same period
in 2001. Sales of electricity decreased by approximately 24.3% to 384,091,000
kWhs during the third quarter of 2002 as compared to approximately 507,549,000
kWhs in the third quarter of 2001. The decrease in kWhs sold was primarily
attributable to the lower sales volume from the resale of purchased power in the
third quarter of 2002 as compared to the same period in 2001.

Expenses

         Production and transmission expenses decreased approximately $870,000,
or 14%, to $5,336,000 in the third quarter of 2002 as compared to $6,206,000 in
the third quarter of 2001. This decrease was primarily attributable to accrued
outage costs recorded in the third quarter of 2001. There were no accrued outage
costs recorded in the third quarter of 2002. Purchased power costs decreased
approximately $5,591,000, from $5,604,000 in the third quarter of 2001 to
$13,000 in the third quarter of 2002. During the third quarter of 2001, Great
Bay purchased power for resale pursuant to a Purchase Power Agreement with
Select Energy. There were no significant power purchases made during the third
quarter of 2002. Administrative and general expenses increased approximately
$1,180,000, or 69.2%, to $2,884,000 in the third quarter of 2002 as compared to
$1,704,000 in the third quarter of 2001. In the third quarter of 2002, the
Company recorded approximately $81,700 in non-cash compensation costs for
employee stock option costs relating to options that were repriced in 1998. The
Company also recorded non-cash compensation costs of approximately $480,400 for
certain options exercised in 2002. See Note E - Equity. Depreciation expense
decreased approximately $57,000, or 5.7%, and taxes other than


                                       15

                             BAYCORP HOLDINGS, LTD.

income decreased approximately $79,000, or 8.6%, during the third quarter of
2002 as compared to the same period in 2001.

         In the third quarter of 2001, Great Bay recorded unrealized gains on
firm forward power sales contracts of $1,316,000. The unrealized gain in the
third quarter of 2001 was due in part to Great Bay committing to sell less power
under firm forward contracts as of September 30, 2001 as compared to June 30,
2001. Sales for the quarter ended September 30, 2002 were made on a unit
contingent basis as opposed to firm sales and the Company had no firm forward
power contracts as of September 30, 2002 that required mark-to-market accounting
treatment.

         Decommissioning cost accretion increased $415,000, or 50.9%, to
$1,231,000 in the third quarter of 2002 as compared to $816,000 in the third
quarter of 2001. 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 period during which the Seabrook Project is
licensed to operate. The change in accretion between periods reflects
adjustments to the estimated decommissioning cost by the NDFC.

         Other income increased approximately $156,000, to $175,000 in the third
quarter of 2002 as compared to $19,000 in other income in the third quarter of
2001. The increase was primarily attributable to interest income earned on
higher average cash balances.

Net Income

         As a result of the above factors, during the third quarter of 2002, the
Company recorded net income of approximately $4,831,000, or approximately $0.58
per share (basic), as compared to net income of approximately $7,871,000, or
approximately $0.94 per share (basic), during the third quarter of 2001.

Results of Operations: First Nine Months of 2002 Compared to the First Nine
Months of 2001

Operating Revenues

         BayCorp's operating revenues decreased by approximately $20,043,000, or
32.8%, to $41,053,000 in the first nine months of 2002 as compared to
$61,096,000 in the first nine months of 2001. The decrease in operating revenues
was primarily attributable to lower sales volume from the resale of purchased
power in the nine months ended September 30, 2002 as compared to the sales
volume from the resale of purchased power in the nine months ended September 30,
2001. During the nine months ended September 30, 2001 the Company was obligated
to sell power on a firm basis. Great Bay purchased power for resale pursuant to
a purchase power agreement to support its firm power sale obligation. There were
no significant purchases of power for resale made during the same period in
2002.

         Sales of electricity decreased by approximately 26.3% to 1,016,800,000
kWhs in the first nine months of 2002 as compared to approximately 1,379,979,000
kWhs in the first nine months of 2001. The Seabrook capacity factor for the
first nine months of 2002 was 88.9% as compared to 83.2% for the first nine
months of 2001. Though Seabrook generation was lower in the first nine months of
2001, due to unscheduled outages for maintenance and repairs, the Company
purchased a significant amount of power for resale during the first nine months
of 2001 as compared to the same period in 2002. During the nine

months ended September 30, 2002, Great Bay's average selling price decreased
9.2%, to 4.04 cents per kWh as compared to an average selling price of 4.43
cents per kWh for the same period in 2001.

Expenses

         Production and transmission expenses increased approximately
$1,614,000, or 9.1%, to $19,293,000 in the first nine months of 2002 as compared
to $17,679,000 in the first nine months of 2001. This increase was primarily
attributable to costs associated with the 2002 refueling outage. Purchased power
costs decreased approximately $22,655,000, from $22,931,000 in the nine months
ended September 30, 2001 to $276,000 in the nine months ended September 30,
2002. During the nine months ended September 30, 2001, Great Bay purchased power
for resale to cover firm sales contracts during unscheduled outages in addition
to purchasing power for resale pursuant to a Purchase Power Agreement with
Select Energy. There were no firm power sales contracts and there were no
significant power purchases made during the nine months ended September 30,
2002. Administrative and general expenses increased approximately $2,255,000, or
46.2%, to $7,137,000 in the first nine months of 2002 as compared to $4,882,000
in the first nine months of 2001. This increase was attributable in part to
higher administrative and general expenses for early retirement and other
employee benefit related costs at Seabrook during the first nine months of 2002
as compared to the first nine months of 2001. In addition, during the nine
months ended September 30, 2002, the Company recorded approximately $322,000 in
non-cash compensation costs for employee stock option costs relating to options
that were repriced in 1998. In addition, the Company recorded non-cash
compensation costs of approximately $803,000 for certain options exercised
during the nine-month period. See Note E - Equity. Depreciation expense
decreased approximately $172,000, or 5.7%, and taxes other than income decreased
approximately $183,000, or 6.5%, during the first nine months of 2002 as
compared to the same period in 2001.

         In the nine months ended September 30, 2001, Great Bay recorded
unrealized gains on firm forward power sales contracts of $14,636,000. The
unrealized gain in the first nine months of 2001 was due in part to Great Bay
committing to sell less power under firm forward power sales contracts as of
September 30, 2001 as compared to December 31, 2000. Sales for the nine months
ended September 30, 2002 were made on a unit contingent basis as opposed to firm
sales and the Company had no firm forward power sales contracts as of September
30, 2002 that required mark-to-market accounting treatment.

         Decommissioning cost accretion increased $1,248,000, or 51.0%, to
$3,694,000 in the nine months ended September 30, 2002 as compared to $2,446,000
in the nine months ended September 30, 2001. 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 period during which the
Seabrook Project is licensed to operate. The change in accretion between periods
reflects adjustments to the estimated decommissioning cost by the NDFC.

         BayCorp made no investments in HoustonStreet in the first nine months
of 2002. BayCorp contributed $450,000 to HoustonStreet in the first nine months
of 2001 and recorded this contribution as an equity loss in HoustonStreet
investment.

                             BAYCORP HOLDINGS, LTD.

         As a result of the above factors, the Company recorded net income of
approximately $6,752,000, or approximately $0.81 per share (basic), for the
first nine months of 2002 as compared to net income of approximately
$22,987,000, or approximately $2.76 per share (basic), for the first nine months
of 2001.

Liquidity and Capital Resources

         As of September 30, 2002, BayCorp had approximately $25,456,000 in cash
and cash equivalents, restricted cash and short-term investments. Approximately
$13,011,000 of the total cash was in short term investments at September 30,
2002. BayCorp's cash receipts for the nine months ended September 30, 2002 was
sufficient to cover the ongoing cash requirements of the Company during that
period. The Company believes that its current cash, together with the
anticipated proceeds from the sale of electricity by Great Bay and Little Bay,
will be sufficient to enable the Company to meet its anticipated cash
requirements.

         The Company had net income of approximately $6,752,000 during the nine
months ended September 30, 2002. Cash expenditures during the first nine months
of 2002 included approximately $1,413,000 for capital additions, $146,000 for
nuclear fuel additions and $1,045,000 in decommissioning trust fund payments.
Additional cash expenditures included an increase in prepaids, deferred debits
and other assets of approximately $1,117,000 primarily for state income tax
payments and a decrease in accounts payable and accrued expenses of
approximately $1,617,000, primarily attributable to payments made in the first
quarter of 2002 for purchased power that was included in the December 31, 2001
accounts payable balance. A decrease of approximately $3,145,000 in
miscellaneous and other liabilities in the first nine months of 2002 was
primarily attributable to costs associated with the Seabrook refueling outage
that were partially accrued for and included in other liabilities. In the first
nine months of 2002, the Company repurchased 110,629 shares of its stock for
approximately $1,240,000.

         Offsetting these cash expenditures were non-cash charges to income of
approximately $2,821,000 for depreciation and amortization, $3,105,000 for
nuclear fuel amortization and $2,547,000 for net decommissioning accretion and
decommissioning trust fund interest and other charges. In addition, there was a
decrease in accounts and other receivables of approximately $1,616,000 in the
first nine months of 2002 due to higher revenues in the month of December 2001
as compared to revenues in the month of September 2002.

         During the first nine months of 2002, the Company recorded a non-cash
compensation charge of approximately $321,700 for employee stock option costs
relating to repriced options. Certain employee stock options were repriced in
December 1998 based on the current market value of the stock at that time. In
accordance with generally accepted accounting principles, these options are
accounted for as a variable plan which gives rise to compensation expense for
subsequent increases in the market price of the stock. Also during the first
nine months of 2002, the Company recorded a non-cash compensation charge of
approximately $803,000 for certain options exercised during the period as
required by generally accepted accounting principles. See Note E - Equity.

         In the first nine months of 2002, cash received from stock option
exercise transactions was approximately $153,000.

         The Company anticipates that its share of the Seabrook Project's
capital expenditures for the 2002 fiscal year will total approximately $5.8
million for nuclear fuel and various capital projects.

Should the proposed transaction for the sale of Seabrook be completed before
year-end, the Company's share of the Seabrook Project's capital expenditures for
2002 may differ from this amount.

         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 revenue 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 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. During the second quarter of 2002, Seabrook conducted a
twenty-eight day refueling outage from May 4 to May 31. The Company's portion of
refueling outage and maintenance expenses for the 2002 refueling outage were
approximately $5,306,000.

         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 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, a proportionate share 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 October 11, 2002 the Company mailed a proxy statement to
shareholders for a special meeting of shareholders to be held on October 29,
2002. At the special meeting, BayCorp shareholders will be asked to consider and
vote upon the proposal to approve the sale of substantially all of the assets
and the assignment of certain liabilities of Great Bay and Little Bay to FPL
Energy Seabrook, LLC ("FPL Energy"), a subsidiary of FPL Group. If the sale is
completed, Great Bay and Little Bay will sell substantially all of their
respective non-cash assets to FPL Energy for their respective proportionate
shares of the purchase price. Because the Company is a holding company having
Great Bay and Little Bay as its primary operating subsidiaries, the sale of
substantially all of the assets of Great Bay and Little Bay may constitute, in
effect, a sale of substantially all of the assets of the Company. As the sole
stockholder of Great Bay and Little Bay, BayCorp has approved the purchase and
sale agreement. As part of the sale, BayCorp will transfer to FPL Energy nearly
all of its liabilities associated with Seabrook, including the decommissioning
liability. BayCorp will retain all of its cash and certain other assets in


                                       19

                             BAYCORP HOLDINGS, LTD.

addition to the sale proceeds. Assuming the exercise of all stock options
currently outstanding, BayCorp would have approximately 9.4 million shares
outstanding.

         While it is the stated desire of all parties to conduct a single
closing, the purchase and sale agreement provides that multiple closings may
occur on a coordinated basis under stated terms and conditions so long as at
least fifty-one percent or more of the ownership interest shares (which must
include Northeast Utilities' ownership share) participate in the initial
closing. Each closing is scheduled to take place 10 days following the date on
which all applicable conditions to the closing have either been satisfied or
waived by the party for whose benefit the condition exists. The current target
date for the initial closing is November 1, 2002, although it is not certain
that the initial closing will occur on that date.

         The Board of Directors has not yet determined what its strategic
direction will be following the consummation of the asset sale and is
considering at least three possible general alternatives. Immediately after the
asset sale closing, on a consolidated basis, BayCorp's material assets will
consist of cash, its interest in HoustonStreet, its Unitil power sales contract
and expected net operating loss carryforwards of approximately $70 million. It
will have no material liabilities other than ordinary course payables and an
obligation to sell power to Unitil under the amended Unitil agreement.
Currently, the Company anticipates pursuing one of the following three
directions: liquidation and dissolution, retention of the proceeds and
acquisition, investment in, or development of new lines of business, or a
partial distribution of cash and acquisition, investment in, or development of
new lines of business. The Company has not yet determined which option it will
pursue. Furthermore, the Company may not choose any of the options described
above and instead may pursue one or more other options the Company has not yet
considered. Although the Board may explore opportunities to acquire, invest in,
or develop new lines of business, to date the Board has not adopted a new
strategic direction for the Company and can not predict what, if any, businesses
it may enter or strategies it may adopt. Therefore, the Board can offer no
indication of what risks and opportunities might arise in the context of such a
new direction or directions.

Commodity Price Risk

         The price of electricity is subject to fluctuation resulting from
changes in supply and demand. Great Bay tracks its market exposure for any firm
forward power sales contracts in a mark-to-market model that is updated daily
with current market prices and any mark-to-market value is reflected in the
company's balance sheet. The positive, or negative, value of Great Bay's
portfolio of firm power commitments represents an estimation of the gain, or
loss, that Great Bay would have experienced if open firm commitments were
covered at then-current market prices. As of December 31, 2001 and as of
September 30, 2002, Great Bay had no firm forward, fixed price power sales
contracts that required mark-to-market accounting treatment.
