                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)

      BIW Limited (BIW or the Company) is the parent company of (i) Birmingham
Utilities, Inc. and its wholly-owned subsidiary Eastern Connecticut Regional
Water Company, Inc. (Eastern Division), (collectively BUI or Birmingham
Utilities), a regulated public water service company that provides water service
to customers in various cities and towns in Connecticut and (ii) Birmingham H2O
Services, Inc. (BHS or H2O Services), which provides non-regulated water-related
services to other water utilities, municipalities, contractors and individuals
throughout Connecticut.

     Birmingham Utilities is subject to the jurisdiction of the Connecticut
Department of Public Utility Control (DPUC) as to accounting, financing,
ratemaking, disposal of property, the issuance of long-term securities and other
matters affecting its operations. The Connecticut Department of Public Health
(the Health Department or DPH) has regulatory powers over BUI under state law
with respect to water quality, sources of supply, and the use of watershed land.
The Connecticut Department of Environmental Protection (DEP) is authorized to
regulate BUI's operations with regard to water pollution abatement, diversion of
water from streams and rivers, safety of dams and the location, construction and
alteration of certain water facilities. BUI's activities are also subject to
regulation with regard to environmental and other operational matters by
federal, state and local authorities, including, without limitation, zoning
authorities.

     In addition, Birmingham Utilities is subject to regulation of its water
quality under the Federal Safe Drinking Water Act (SDWA). The United States
Environmental Protection Agency has granted to the Health Department the primary
enforcement responsibility in Connecticut under the SDWA. The Health Department
has established regulations containing maximum limits on contaminants, which
have or may have an adverse effect on health.

NOTE 1 - QUARTERLY FINANCIAL DATA

     The accompanying consolidated financial statements of BIW Limited have been
prepared in accordance with accounting principles generally accepted in the
United States of America, without audit, except for the Balance Sheet for the
year ended December 31, 2006, which has been audited. The interim financial
information conforms to the instructions to Form 10-Q and Rule 10-01 of
Regulation S-X and, as applied in the case of rate-regulated public utilities,
complies with the Uniform System of Accounts and ratemaking practices prescribed
by the DPUC. In management's opinion, these consolidated financial statements
include all adjustments (consisting only of normal recurring adjustments)
necessary for a fair presentation of the results of operations for the interim
periods presented. Certain information and footnote disclosures required by
accounting principles generally accepted in the United States of America have
been

                                        5
<PAGE>

omitted, pursuant to such rules and regulations; although the Company believes
that the disclosures are adequate to make the information presented not
misleading.

     In the first quarter of 2006, the Company adopted Statement of Financial
Accounting Standards No. 123R, "Share-Based Payment" (SFAS 123R) using the
modified prospective method. Under the modified prospective method, compensation
cost is recognized for all share-based payments granted after the adoption of
SFAS 123R and for all awards granted to employees prior to the adoption date of
SFAS 123R that were unvested on the adoption date. Accordingly, no restatements
were made to prior periods. Prior to the adoption of SFAS 123R, the Company
applied Statement of Financial Accounting Standards No. 123, "Accounting for
Stock Based Compensation" (SFAS 123) to account for its stock option plans. As
permitted by SFAS 123, the Company had chosen to apply Accounting Principles
Board Opinion No. 25, "Accounting for Stock Issued to Employees" in accounting
for its employee stock compensation plans. Accordingly, no compensation expense
was recognized for its employee stock option issuances, as stock options were
issued with an exercise price at least equal to the closing price at the date of
grant.

     In September 2006, the FASB issued SFAS No. 158, "Employers' Accounting for
Defined Benefit Pension and Other Postretirement Plans, an Amendment of FASB
Statements No. 87, 88, 106, and 132(R)" (SFAS 158). SFAS 158 requires companies
to recognize the overfunded or underfunded status of a defined benefit
postretirement plan as an asset or liability in its balance sheet and to
recognize changes in the funded status in the year in which the changes occur
through comprehensive income. SFAS 158 also requires the funded status of a plan
to be measured as of the balance sheet date. The Company adopted the provisions
of SFAS 158 effective December 31, 2006. The adoption of SFAS 158 did not have a
material impact on the Company's financial statements.

     For further information, refer to the financial statements and accompanying
footnotes included in the Company's Annual Report on Form 10-K for the year
ended December 31, 2006.

     Birmingham Utilities' business of selling water is to a certain extent
seasonal because water consumption normally increases during the warmer summer
months. Another factor affecting the comparability of various accounting periods
includes the timing of rate increases. In addition, H2O Services' business
activities slow in the winter months. Accordingly, annualization of the results
of operations for the three months ended March 31, 2007 and 2006 would not
necessarily accurately forecast the annual results of each year.

NOTE 2 - PRINCIPLES OF CONSOLIDATION

     The consolidated financial statements include the accounts of BIW Limited
and its wholly owned subsidiaries Birmingham Utilities, Inc. and Birmingham H2O
Services, Inc. All significant intercompany balances and transactions have been
eliminated in consolidation.

NOTE 3 - WATER SERVICE RATE INCREASE

                                        6
<PAGE>

     On November 27, 2006, the DPUC granted Birmingham Utilities a 16.2 percent
water service rate increase designed to provide a $1,172,148 annual increase in
revenues and a 10.2 percent ratemaking cost of common equity. The rate order
allowed BUI to combine its Ansonia and Eastern divisions for ratemaking
purposes.

     In October 2005, the Ansonia division of Birmingham Utilities filed an
application with the DPUC for a 4.4%, $258,655 water service rate increase to
account specifically for increases in purchased water costs and property taxes.
This limited rate filing is allowed under Section 16-32c of the Connecticut
General Statutes. The DPUC granted BUI's request in its entirety in January
2006.

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

     Management's Discussion and Analysis of the Financial Condition and Results
of Operations contained in the Company's Annual Report on Form 10K for the year
ended December 31, 2006 should be read in conjunction with the comments below.

     Birmingham Utilities, a regulated public water service company, collects
and distributes water for domestic, commercial and industrial uses and fire
protection in the Naugatuck Valley towns of Ansonia, Derby and small parts of
Seymour, Connecticut. The Company refers to this operation as its Ansonia
Division. Water service is also provided for domestic and commercial use in 33
satellite water operations in 16 towns in eastern Connecticut, which form BUI's
Eastern Division. This division, which was acquired in 2003, was the former
Eastern Connecticut Regional Water Company, Inc.

     H2O Services, the Company's non-regulated subsidiary, offers a consumer
protection program for residential service lines and provides water related
services to other water utilities, municipalities, contractors and individuals
throughout Connecticut. H2O Services operates from both the Ansonia and Eastern
Divisions as well as from another location in Guilford, CT. Non-regulated
operations from the Ansonia Division principally relate to construction
activities including the installation of water mains, services and other water
related infrastructure. Non-regulated operations at the Eastern Division
principally relate to the operation of other water systems not owned by the
Company through contract operations. Non-regulated operations from our Guilford,
CT location relate to Rhodes Pump Service, a residential pump and filter
services business.


CAPITAL RESOURCES AND LIQUIDITY

     Completion of Birmingham Utilities' Long Term Capital Improvement Program
will be funded from the internal generation of funds, including rate relief, as
well as BUI's ability to raise capital from external sources. For the three
months ended March 31, 2007 and 2006, BUI's additions to utility plant, net of
customer advances, were $839,941 and $633,823 respectively (See Statement of
Cash Flows).

     Birmingham Utilities has outstanding a series of first mortgage bonds in
the amount of $9,000,000 due on April 15, 2011, issued under its Mortgage
Indenture. The bonds carry an interest rate of 5.21%. The terms of the indenture
provide, among other things, limitations on (a) payment of cash dividends; and
(b) incurrence of additional bonded indebtedness. Interest is payable
semi-annually on the 15th day of April and October.

     Note Payable consists of a $9,000,000 unsecured line of credit, which will
expire in September 2007. During the revolving period, Birmingham Utilities can
choose

                                        8
<PAGE>

between variable rate options of 30, 60, 90 or 180-day LIBOR plus 100 basis
points or prime. BUI is required to pay only interest during the revolving
period. The principal is payable in full at maturity. The line of credit
requires the maintenance of certain financial ratios and net worth of
$7,500,000. BUI was in compliance with all covenants as of March 31, 2007. The
Company believes that it will be able to extend or replace the existing line of
credit upon its expiration.

Results of Operations for the Three Months Ended March 31, 2007 and 2006
------------------------------------------------------------------------

Operating Revenues
------------------

     Operating revenues of $2,304,891 for the first three months of 2007 are
$264,794 or 13% higher than the comparable 2006 period. The increase is
primarily due to the 16.2% rate increase granted to Birmingham Utilities, which
became effective on November 27, 2006. The increase is partially offset by a 3%
decline in H2O Services due to less demand for its services in the winter
months.

Operating and Maintenance Expenses
----------------------------------

     Operating and maintenance expenses for the first three months of 2007 of
$1,454,885 are $4,345 lower than comparable costs for the first three months of
2006. Increased purchased water costs and power costs in the regulated
operations were offset by decreased salary expense due to a smaller workforce
achieved through a combining of positions in the two divisions. Operating
expenses for H2O Services decreased due to less construction activity.

Depreciation
------------

     Depreciation for the first three months of 2007 of $273,750 is $4,999
higher than the comparable 2006 period, due to plant additions and improvements
made over the last two years.

Taxes Other Than Income Taxes
-----------------------------

     Taxes other than income taxes for the three month period ended March 31,
2007 is $6,513 higher than the comparable 2006 period. Increased municipal
property taxes as a result of plant additions and improvements accounts for this
increase.

Other Income
------------

     Other income for the first three months of 2007 of $36,745 is $10,277
higher than the comparable three month period in 2006. Increased AFUDC for
capital projects accounts for the difference.

Interest Expense
----------------

                                        9
<PAGE>

     Interest expense of $262,572 recorded in the first three months of 2007 is
$61,044 higher than the comparable 2006 period. The increase in short term
borrowings as well as higher interest rates account for the additional expense.


ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

            The Company has certain exposures to market risk related to changes
in interest rates. There have been no material changes in market risk since the
filing of the Company's Annual Report on Form 10-K for the fiscal year ended
December 31, 2006.


ITEM 4T. CONTROLS AND PROCEDURES

     The Company maintains disclosure controls and procedures that are designed
to ensure that information required to be disclosed in the Company's Exchange
Act reports is recorded, processed, summarized and reported within the time
periods specified in the SEC's rules and forms, and that such information is
accumulated and communicated to the Company's management, including its Chief
Executive Officer and Chief Financial Officer, as appropriate, to allow timely
decisions regarding required disclosure based on the definition of "disclosure
controls and procedures" in Rule 13a-15(e). In designing and evaluating the
disclosure controls and procedures, management recognized that any controls and
procedures, no matter how well designed and operated, can provide only
reasonable assurance of achieving the desired control objectives, and management
necessarily was required to apply its judgment in evaluating the cost-benefit
relationship of possible controls and procedures.

     As of March 31, 2007, the Company carried out an evaluation, under the
supervision and with the participation of the Company's management, including
the Company's Chief Executive Officer and the Company's Chief Financial Officer,
of the effectiveness of the design and operation of the Company's disclosure
controls and procedures. Based on the foregoing, the Company's Chief Executive
Officer and Chief Financial Officer concluded that the Company's disclosure
controls and procedures were effective as of March 31, 2007.

     There have been no changes in the Company's internal control over financial
reporting during the quarter ended March 31, 2007 that have materially affected,
or are reasonably likely to materially affect the Company internal control over
financial reporting.
