Dear Shareholder:

   The enclosed information relates to a Special Meeting of the Shareholders of
The New Canaan Company ("NCC") to be held on ____________, 1995, at the offices
of NCC, 59 Grove Street, New Canaan, Connecticut, to consider (i) a proposal to
sell substantially all the assets of NCC, including all of the capital stock of
New Canaan Water Company ("NCWC") and The Ridgefield Water Supply Company
("RWSC") owned by NCC (the "Asset Sale"), to Bridgeport Hydraulic Company
("BHC"), (ii) an amendment to NCC's Certificate of Incorporation to provide that
the liquidation preference of NCC's Class A Common Stock may be paid in cash or
in other property (the "Amendment") and (iii) a Plan of Liquidation for NCC
pursuant to Internal Revenue Code Section 368(a)(1)(C) (the "Plan of
Liquidation"). All three of the proposals must be approved by the shareholders
of NCC in order for any of the proposals to become effective. If the Asset Sale,
the Amendment and the Plan of Liquidation are all approved by the shareholders
of NCC, shares of Common Stock, no par value ($1 per share stated value)
("Aquarion Common Stock"), of Aquarion Company ("Aquarion"), the parent Company
of BHC, with a value of $3.5 million, less the amount of certain transaction
costs, including a payment to an officer of NCC (see "Interests of Certain
Persons in the Transaction") and indebtedness of NCC to be paid by BHC (as
adjusted, the "Purchase Price"), will be issued by Aquarion in connection with
the Asset Sale. The shares of Aquarion Common Stock to be issued to NCC will be
valued at the average of the daily closing prices of Aquarion Common Stock as
reported on the composite tape for New York Stock Exchange listed securities for
the thirty consecutive business days commencing with the 45th business day prior
to the date of closing of the Asset Sale. The exact number of shares to be
issued is therefore not yet determinable, although the Asset Sale is subject to
the condition that no more than 140,000 shares or less than 87,500 shares be
issued by Aquarion. In addition to the Purchase Price, BHC will also pay a
specified liability of NCC in an amount not to exceed $130,000 at the closing of
the Asset Sale. Ten percent of the shares of Aquarion Common Stock issued as
payment of the Purchase Price shall be paid to the escrow agent for the escrow
fund. Pursuant to the Plan of Liquidation and the Amendment, holders of NCC
Class A Common Stock will receive, for each share of Class A Common Stock, a
number of shares of Aquarion Common Stock with a value equal to $35.00 (on the
basis of the value determined as described in the next preceding sentence) plus
all accrued but unpaid dividends on the Class A Common Stock to the date of
liquidation, and the balance shall be paid to the holders of the Class B Common
Stock, pro rata based on each such holder's ownership interest in Class B Common
Stock immediately prior to the Liquidation. Escrow shares not applied to the
payment of indemnification obligations will be distributed to the former holders
of the Class B Common Stock in accordance with the Escrow Agreement (as
hereinafter defined) after the termination thereof.

   Whether or not you plan to attend the meeting, I urge you to read carefully
the information contained in the accompanying Prospectus of Aquarion and Proxy
Statement of NCC and to cast your proxy vote as soon as possible.

   As you review this information, I would like to direct your attention to a
number of issues we consider crucial in making a decision on this vital matter:

    .  The Board of Directors of NCC has carefully reviewed the Asset Sale, the
       Amendment and the Plan of Liquidation and the Board has approved the
       Asset Sale, the Amendment and the Plan of Liquidation.

    .  The Board has concluded that the Asset Sale, the Amendment and the Plan
       of Liquidation are in the best interests of the shareholders of NCC and
       recommends that each shareholder vote FOR the proposal.

    .  The financial condition of NCC and its two subsidiaries, NCWC and RWSC,
       is tenuous due to the lack of equity or other capital available to NCC or
       its subsidiaries. If the Asset Sale is not approved by the shareholders
       or does not occur for any reason, RWSC and NCWC will need to obtain
       additional sources of financing and/or additional rate relief from the
       Connecticut Department of Public Utility Control in order to repay their
       respective debts and perform needed capital improvements. It is uncertain
       whether RWSC or NCWC could obtain the level of financing or rate relief
       needed.
<PAGE>
 
   We appreciate the loyalty and support our shareholders have demonstrated over
the years. We hope that you will continue this support by voting FOR the
proposals now. I and all the other officers and directors of NCC, intend to vote
FOR the proposals, and recommend that all shareholders do the same.

   PLEASE SIGN AND RETURN YOUR PROXY CARD PROMPTLY. THE AFFIRMATIVE VOTE OF THE
HOLDERS OF AT LEAST TWO-THIRDS OF THE OUTSTANDING SHARES OF EACH CLASS OF COMMON
STOCK OF NCC IS REQUIRED FOR THE APPROVAL OF THE ASSET SALE AND THE AMENDMENT
AND THE VOTE OF THE HOLDERS OF AT LEAST TWO-THIRDS OF THE OUTSTANDING SHARES OF
CLASS B COMMON STOCK IS REQUIRED FOR THE APPROVAL OF THE LIQUIDATION. YOUR VOTE
IS IMPORTANT. ACCORDINGLY, EVEN IF YOU PLAN TO ATTEND THE MEETING, PLEASE DATE
AND SIGN THE ENCLOSED PROXY AND RETURN IT PROMPTLY IN THE ENCLOSED ENVELOPE.

                                         Sincerely yours,


                                         _______________________________
                                         Name:    Joseph J. McLinden
                                         Title:   President


      NOTE:  DO NOT SEND IN YOUR STOCK CERTIFICATE(S) AT THE PRESENT TIME.

IMPORTANT

          If your shares are being held for you in "street name" or in a trust,
only the registered holder can sign a proxy on your behalf, and only upon
receipt of specific instructions. Please contact the person responsible for your
account and give instructions for execution of the proxy card on your behalf. If
you require additional material or assistance in voting you may contact Derrel
M. Mason, Esq., Gregory & Adams, P.C. at (203) 762-9000.

                     For a Special Meeting of Shareholders
                        to be Held on ____________, 1995

                                  ----------

  This Prospectus of Aquarion Company and Proxy Statement of The New Canaan
Company (the "Prospectus/Proxy Statement") relates to the proposed acquisition
(the "Acquisition") by Bridgeport Hydraulic Company ("BHC"), a subsidiary of
Aquarion Company ("Aquarion"), of substantially all the assets of The New Canaan
Company ("NCC") for Aquarion Common Stock, no par value ($1 per share stated
value) (the "Aquarion Common Stock"), the approval and adoption by NCC of an
amendment to NCC's Certificate of Incorporation to provide that the liquidation
preference of NCC's Class A Common Stock may be paid in cash or in other
property (the "Amendment") and the adoption and approval by NCC of a Plan of
Liquidation, pursuant to Section 368(a)(1)(C) of the Internal Revenue Code (the
"Plan of Liquidation"). In return for substantially all the assets of NCC,
Aquarion will repay certain indebtedness of NCC in an amount not to exceed
$130,000 and will transfer to NCC shares of Aquarion Common Stock with a value
of $3,500,000, less the amount of certain of NCC's transaction costs, including
a payment to an officer of NCC (see "Interests of Certain Persons in the
Transaction") and indebtedness to be paid by BHC (as adjusted, the "Purchase
Price"). The Acquisition is being made pursuant to an Acquisition Agreement,
dated September 2, 1992, by and among Aquarion, BHC and NCC as thereafter
amended from time to time (the "Acquisition Agreement").

  Upon completion of the Acquisition and the effectiveness of the Amendment, NCC
will proceed to implement the Plan of Liquidation by distributing the Aquarion
Common Stock received as the Purchase Price to the holders of NCC common stock
(the "NCC Shareholders"), in accordance with the provisions of NCC's Certificate
of Incorporation and the Plan of Liquidation. NCC Shareholders who dissent from
the Acquisition and Plan of Liquidation have certain rights of appraisal
pursuant to Connecticut law. See "Rights of Dissenting Shareholders." The number
of shares of Aquarion Common Stock equalling the Purchase Price to be received
and distributed by NCC is dependent on the trading price of Aquarion Common
Stock on the New York Stock Exchange ("NYSE").

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION. NEITHER THE SECURITIES
AND EXCHANGE COMMISSION NOR ANY STATE SECURITIES COMMISSION HAS PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.

  Aquarion Common Stock is listed on the NYSE under the symbol "WTR". On
____________, 1995 the reported last sale price on the NYSE was $_____.

  The consummation of the Acquisition is subject to various conditions,
including the receipt of required regulatory approvals, the approval of the
Acquisition, the Amendment and the Plan of Liquidation by the shareholders of
NCC at the Special Meeting of Shareholders of NCC to be held ____________, 1995,
and the closing of the Property Exchange Agreement dated October 21, 1992, as
amended, among Second Taxing District of the City of Norwalk, Monroe
Environmental Leasing Partnership, Aquarion and NCC, which is an integral part
of the Acquisition. See "Property Exchange Agreement."

                                  The description of its contents that follows
                                  is necessarily incomplete; reference is made
                                  to the Acquisition Agreement itself for a
                                  complete description of each matter and of all
                                  of the terms and conditions of the
                                  Acquisition. 

                                  The Acquisition Agreement provides for the
                                  sale of the Assets to BHC in return for BHC's
                                  repayment of certain indebtedness of NCC in an
                                  amount not to exceed $130,000 and Aquarion
                                  Common Stock valued at $3,500,000 less the
                                  amount of certain of NCC's transaction costs
                                  and indebtedness paid by BHC in cash at the
                                  closing. It is currently estimated that at
                                  September 30, 1994 the amount of $3,500,000
                                  would have been reduced by approximately
                                  $750,000.

                                  Such $750,000 consists of (i) approximately
                                  $300,000 of legal fees, accountants' fees and
                                  other transaction related expenses for which
                                  NCC is liable, which liabilities will be
                                  assumed and paid by BHC; (ii) a payment of
                                  $105,000 agreed to be made by NCC to Mr.
                                  McLinden in respect of his role in negotiating
                                  the Acquisition, which liability will be
                                  assumed and paid by BHC; (iii) approximately
                                  $168,000 of liabilities of NCC and its
                                  subsidiaries to certain of NCC's shareholders,
                                  which will be assumed and paid by BHC at the
                                  Closing; and (iv) approximately $177,000,
                                  representing the estimated amount of certain
                                  other liabilities of NCWC and RWSC.

                                  Each share of Aquarion Common Stock will be
                                  valued at the average of the daily closing
                                  prices of Aquarion Common Stock as reported on
                                  the composite tape for NYSE listed securities
                                  for the thirty consecutive business days
                                  commencing with the 45th business day prior to
                                  the date of closing. The exact number of
                                  shares to be issued is therefore not yet
                                  determinable, although the Acquisition
                                  Agreement provides that the obligations of
                                  Aquarion and NCC to close the Acquisition are
                                  subject to the requirement that no more than
                                  140,000 or less than 87,500 shares be issued
                                  by Aquarion for the Acquisition. The value of
                                  the Aquarion Common Stock deliverable to NCC
                                  is subject to adjustment if NCC's indebtedness
                                  on a certain promissory note in the principal
                                  amount of $130,000, which indebtedness BHC
                                  will assume, is greater than that amount or if
                                  indebtedness of NCWC or RWSC has increased
                                  from the level reported on NCC's March 31,
                                  1992 balance sheet, or if certain liabilities
                                  of NCWC or RWSC have not been discharged prior
                                  to the Closing Date (as defined below). The
                                  balance payable on such $130,000 promissory
                                  note was less than $130,000 on November 30,
                                  1994. The Acquisition Agreement also provides
                                  that 10% of the Aquarion Common Stock to be
                                  issued to NCC in payment of the Purchase Price
                                  will be placed in escrow for a period not to
                                  exceed one year following the Closing Date to
                                  be applied to obligations of the shareholders
                                  of NCC to indemnify BHC and its affiliates
                                  against certain liabilities that might result
                                  from the consummation of the Acquisition.

                                  Conditions to the Acquisition. In addition to
                                  approval of the Acquisition, the Amendment and

                                  transactions agreed to in the Acquisition
                                  Agreement (the "Acquisition Closing") are
                                  subject to satisfaction or waiver of certain
                                  conditions, the most significant of which are:

                                  (ii) the binding and unconditional status of

                                  relating to the tax treatment of the
                                  Acquisition and the Plan of Liquidation; (iv)
                                  the requirement that Aquarion not be required
                                  to issue more than 140,000 nor less than
                                  87,500 shares of Aquarion Common Stock in

                                  there be no material adverse change in the

                                  Property Exchange Agreement. An integral part
                                  of the Transaction is a three-cornered
                                  property exchange pursuant to a Property
                                  Exchange Agreement, dated October 21, 1992,
                                  among MELP, STD, Aquarion and NCWC (the
                                  "Property Exchange Agreement"). The Property
                                  Exchange Agreement, which is to be consummated
                                  immediately after the Acquisition Closing,
                                  provides that MELP will transfer to NCWC a
                                  commercial building and the property on which
                                  it is situated, NCWC will in turn transfer a
                                  reservoir and related property to STD, which
                                  in turn will pay $2.2 million to MELP, which
                                  will also receive $285,000 from Aquarion,
                                  which amount will be increased by the rate of
                                  inflation to the Property Exchange Closing (as
                                  defined below).

                                  A copy of the Property Exchange Agreement and
                                  the Amendment thereto are annexed as Exhibits
                                  D and E to this Prospectus/Proxy Statement and
                                  is incorporated herein by reference. The
                                  description of its contents herein is
                                  necessarily incomplete; and reference is made
                                  to the Property Exchange Agreement itself for
                                  a complete description of each matter and of
                                  all the terms and conditions of the property
                                  exchange transaction.

                                  Consummation of the transactions agreed to in
                                  the Property Exchange Agreement (the "Property
                                  Exchange Closing") is also subject to the
                                  satisfaction or waiver of certain conditions,
                                  the most significant of which are: (i) the
                                  receipt of regulatory approvals described
                                  below under "Regulatory Approvals"; (ii) the
                                  completion of the Acquisition Closing; (iii)
                                  receipt of certain inspection reports,
                                  environmental assessments and easements; (iv)
                                  receipt of a consent of the Town of New Canaan
                                  and (v) development of a specified alternate
                                  means of water supply for customers of NCWC.
                                  It is anticipated that the conditions
                                  described in (iii), (iv) and (v) will be
                                  obtained or waived before January 31, 1995,
                                  with the exception of one easement which it is
                                  anticipated will be obtained before the
                                  Closing.

                                  Closing Date. The parties expect that the
                                  Acquisition Closing will occur on the earliest
                                  practicable date (the "Closing Date")
                                  following the approval of the Acquisition, the
                                  Amendment and the Plan of Liquidation by the
                                  requisite vote of the NCC Shareholders and the
                                  receipt of all requisite regulatory
                                  approvals.

Plan of Liquidation. . . . . .    The Plan of Liquidation provides that, upon
                                  completion of the Transaction and the filing
                                  of the Amendment, NCC will be liquidated in
                                  accordance with the CSCA and the Aquarion
                                  Common

                                  Stock then owned by NCC will be distributed to
                                  the NCC Shareholders. NCC will first transfer
                                  to the Escrow Agent 10% of the number of
                                  shares of Aquarion Common Stock received as
                                  the Purchase Price. In addition, payments will
                                  be made to any Dissenting Shareholders.
                                  Holders of Class A Common Stock will receive,
                                  for each share of Class A Common Stock, shares
                                  of Aquarion Common Stock with a value
                                  (calculated in accordance with the Acquisition
                                  Agreement) equal to $35.00, plus accrued and
                                  unpaid dividends thereon to the date of the
                                  liquidation. The remaining shares of Aquarion
                                  Common Stock will be distributed to holders of
                                  Class B Common Stock. In addition, the
                                  expenses of the administration of the escrow
                                  fund, the liquidation of NCC, the cost of
                                  liquidating shares of Aquarion Common Stock to
                                  make payments in lieu of fractional shares and
                                  payments, if any, to Dissenting Shareholders
                                  will be paid by liquidating Aquarion shares
                                  received as Purchase Price and will reduce the
                                  number of shares of Aquarion Common Stock
                                  received by holders of Class B Common Stock.
                                  Finally, NCC has agreed to pay to Joseph J.
                                  McLinden an amount equal to 3% of the Purchase
                                  Price at the Closing of the Acquisition, which
                                  amount will also reduce the distribution to
                                  holders of Class B Common Stock. Shares held
                                  in escrow not applied to the payment of
                                  indemnification obligations will be
                                  distributed to the former holders of the Class
                                  B Common Stock in accordance with the Escrow
                                  Agreement after the termination thereof. The
                                  right to receive shares of Aquarion Common
                                  Stock from the escrow account will not be
                                  transferable by the former holders of Class B
                                  Common Stock. The exact number of shares of
                                  Aquarion Common Stock a holder of Class B
                                  Common Stock will receive will be based on
                                  each holder's proportionate ownership of Class
                                  B Common Stock on the Closing Date. There will
                                  be no fractional shares of Aquarion Common
                                  Stock distributed.

The Amendment. . . . . . . . .    The Certificate of Incorporation of NCC
                                  currently provides that in the event of a
                                  voluntary liquidation or dissolution of NCC,
                                  the holders of the Class A Common Stock are
                                  entitled to receive $35.00 per share plus
                                  accrued but unpaid dividends to the date of
                                  liquidation or dissolution. After the holders
                                  of the Class A Common Stock are paid in full,
                                  the remaining assets are distributed to the
                                  holders of the Class B Common Stock, ratably
                                  in accordance with their respective ownership
                                  of such stock. NCC wishes to amend the
                                  Certificate of Incorporation to provide that
                                  the liquidation preference payable to the
                                  holders of Class A Common Stock may be paid in
                                  cash or in other property. Because the
                                  Acquisition provides for the payment of the
                                  Purchase Price in shares of Aquarion Common
                                  Stock which will then be distributed to the
                                  shareholders of NCC in the liquidation, NCC
                                  will distribute such stock, and not cash, in
                                  the liquidation. The amendment is meant to
                                  make clear that such a distribution is
                                  permitted under NCC's Certificate of
                                  Incorporation.

Recommendation of the Board of
  Directors of NCC. . . . . .     The NCC Board of Directors believes that the
                                  Acquisition, the Amendment and the Plan of
                                  Liquidation are in the best interests of, and
                                  are fair to, the shareholders of NCC and has
                                  approved the

                                  Acquisition, the Amendment and the Plan of
                                  Liquidation. The NCC Board recommends that
                                  each shareholder of NCC vote FOR the
                                  Acquisition, the Amendment and the Plan of
                                  Liquidation. In reaching their determination,
                                  the NCC Board members considered a number of
                                  factors, including the difficulties
                                  experienced by NCWC and RWSC in obtaining
                                  adequate financing and revenues to operate
                                  their businesses as required by current laws
                                  and regulations; the monetary terms of the
                                  Acquisition; the fact that NCC Shareholders
                                  will receive Aquarion Common Stock as part of
                                  the Acquisition and Plan of Liquidation, which
                                  represents shares of a larger company listed
                                  on the NYSE, with a long history of
                                  uninterrupted dividend payments; that the
                                  receipt of Aquarion Common Stock is intended
                                  to be a non-taxable transaction; and the
                                  economies of scale that should result from the
                                  Acquisition (such as reduced operating
                                  expenses and lower costs of borrowing).

Approvals of the Boards of 
  Directors of BHC and Aquarion.  The Aquarion and BHC Board each has approved
                                  the Acquisition and believes it to be in the
                                  best interests of Aquarion and BHC. Each Board
                                  believes that the Acquisition represents an
                                  opportunity for BHC to expand its public water
                                  supply business in the State of Connecticut.
                                  The service areas of both NCWC and RWSC adjoin
                                  areas where BHC is franchised to supply water,
                                  and most of NCWC's water supply is provided by
                                  BHC through a regional pipeline. NCWC is also
                                  bordered by BHC's Stamford Water Company 
                                  ("SWC") subsidiary. Therefore, the
                                  Acquisition will enable BHC, either directly
                                  or through SWC, to supervise and coordinate
                                  the operations of these companies with greater
                                  economy than could be achieved through
                                  separate ownership. The Acquisition is
                                  therefore a natural geographic fit which will
                                  expand Aquarion's core water supply business,
                                  integrate water supply planning, and maximize
                                  opportunities for shared efficiencies. The
                                  Boards believe that the receipt by NCWC, when
                                  it is an Aquarion subsidiary, of the
                                  commercial building and related land from
                                  MELP, as contemplated by the Property Exchange
                                  Agreement, together with the acquisition of
                                  the assets of NCC justify the gross
                                  consideration of $3.5 million and the
                                  assumption of $130,000 of debt to be paid for
                                  the Acquisition. With STD's participation
                                  through the Property Exchange Agreement, the
                                  Boards consider the net investment in the
                                  remaining assets of NCWC and RWSC will be
                                  profitable in the long term. The Boards
                                  further believe that the willingness of STD
                                  and MELP to participate in the Property
                                  Exchange, thereby enabling the tax liability
                                  associated with the gain on the sale of the
                                  Reservoir to be deferred, is beneficial.

                                  to Dissenting Shareholders shall be paid by
                                  NCC and shall reduce the number of shares of
                                  Aquarion Common Stock payable to holders of
                                  Class B Common Stock. See "Rights of
                                  Dissenting Shareholders".

Resale of Aquarion Common Stock.  The shares of Aquarion Stock to be distributed
                                  to NCC shareholders pursuant to the Plan of
                                  Liquidation have been registered under the
                                  Securities Act of 1933 (the "Securities Act")
                                  and, in accordance with the provisions of Rule
                                  145 thereunder ("Rule 145"), may be freely
                                  traded by shareholders, who, at the time of
                                  the Special Meeting are not affiliates of NCC.
                                  See "Proposed Acquisition--Resale of Aquarion
                                  Common Stock". The Acquisition Agreement
                                  provides that shares of Aquarion Common Stock
                                  distributed to NCC Shareholders may not be
                                  sold for a period of four months from the
                                  Acquisition Closing Date.

Certain Federal Income Tax
  Consequences. . . . . . . . .   It is intended that the Acquisition and the
                                  Plan of Liquidation will qualify for federal
                                  income tax purposes, as a reorganization
                                  within the meaning of Section 368(a)(1)(C) of
                                  the Internal Revenue Code of 1986, as amended.
                                  Two important federal income tax consequences
                                  will result from such a qualification: (1) no
                                  taxable gain or loss will be recognized by
                                  NCC, BHC or Aquarion as a result of the
                                  Acquisition, and (2) each NCC Shareholder who
                                  receives Aquarion Common Stock in a
                                  liquidation distribution of NCC will not
                                  recognize any taxable gain or loss as a result
                                  of the Asset Sale and Plan of Liquidation.

                                  The consummation of the Acquisition Agreement
                                  is conditioned on receipt of an opinion from
                                  NCC's tax counsel concerning certain federal
                                  income tax consequences of the Acquisition and
                                  the Plan of Liquidation, including (i) that
                                  the Acquisition and the Plan of Liquidation
                                  will qualify as a reorganization under Section
                                  368 of the Code and (ii) that the shareholders
                                  of NCC will generally recognize no taxable
                                  gain or loss on the receipt of Aquarion Common
                                  Stock in the transactions.

Regulatory Approvals . . . . .    The Acquisition Closing and the Property
                                  Exchange Closing are subject to obtaining the
                                  approvals of several Connecticut regulatory
                                  agencies. The DPUC must approve the transfer
                                  to BHC of a controlling interest in the stock
                                  of NCWC and RWSC, as well as the transfer of a
                                  reservoir and certain related property from
                                  NCWC to STD. The DPUC issued such approvals on
                                  June 30, 1993, but subsequently reopened its
                                  approval proceeding to consider the ability of
                                  NCWC to repay an outstanding loan of $1.25
                                  million with the proceeds of the sale of a
                                  certain parcel of land. No final decision has
                                  yet been issued in the reopened proceeding.
                                  BHC and NCC have agreed that the Acquisition
                                  will close if the sale of land by NCWC and the
                                  retirement of NCWC debt do not take place
                                  prior to the Closing. However, the effect on
                                  the acquisition of any other terms and
                                  provisions of a DPUC approval, not
                                  contemplated by the agreement between BHC and
                                  NCC, cannot be predicted. The transfer of the
                                  reservoir to STD as a raw drinking water
                                  supply source must be approved by the DPHAS,
                                  before which a permit application is pending.
                                  It is expected that the permit will be issued
                                  upon submission of final information regarding
                                  ownership after the

                                  proposed transfer takes place of watershed and
                                  non-watershed land. A diversion permit from
                                  the DEP is required in order for STD to use
                                  water from the NCWC reservoir in STD's system.
                                  The DEP issued a diversion permit satisfactory
                                  to STD and to a group of area residents in
                                  July, 1994, but two local residents petitioned
                                  the DEP to issue a declaratory ruling to the
                                  effect that the permit should not have been
                                  issued without a public hearing. The DEP
                                  denied the petition, but it is possible that
                                  the petitioners will seek judicial review of
                                  the DEP's ruling. STD has indicated that it
                                  will proceed with the Property Exchange
                                  Closing notwithstanding the existence of
                                  judicial or regulatory challenge to the
                                  issuance by the DEP of the diversion permit.

  A recent last reported sale price for Aquarion's common stock on the NYSE
composite tape is ___________.

  On April 23, 1990, the date preceding the public announcement of the execution
of the Letter of Intent relating to the Acquisition, the closing price per share
of Aquarion Common Stock, as reported on the NYSE composite tape was 23 1/8.

                                       15
<PAGE>
 
  As of September 30, 1994, there were 6,871 holders of record of Aquarion's
common stock.

  Aquarion has declared and paid quarterly dividends on its common stock without
interruption since its organization in 1969, and prior thereto, BHC paid
dividends on its common stock each year without interruption since 1890.
Dividends, when declared, are normally paid on the 30th day of January, April,
July and October.

  The earnings of Aquarion are derived from its investments in its subsidiaries,
particularly BHC. Aquarion's future ability to pay dividends to holders of its
common stock is dependent upon the continued payment by BHC of dividends to
Aquarion. BHC's ability to pay dividends will depend upon timely and adequate
rate relief, compliance with restrictions under certain of the BHC debt
instruments and other factors. In addition, no dividends on BHC's common stock
can be paid during any period in which BHC's preferred stock dividends are in
arrears. There are no shares of BHC preferred stock outstanding.

  Dividends on common stock of Aquarion can be paid only out of net profits and
surplus of Aquarion. Aquarion's ability to pay dividends is further restricted
by the terms of Aquarion's 7.8% unsecured Senior Notes due 1997 and 5.95%
unsecured Senior Notes due 1999 (the "Aquarion Notes") and by similar terms in
Revolving Credit Agreements dated as of May 14, 1993, providing short-term
borrowing arrangements from each of five banks to Aquarion (collectively, the
"Revolving Credit Agreement"). As of September 30, 1994, the applicable
restrictions would have permitted payment of additional dividends on Aquarion's
common stock of up to $34,022,000. This amount, adjusted by results for the
remainder of 1994, will be unrestricted under the Aquarion Notes and the
Revolving Credit Agreement for payment of dividends in 1994.

  While Aquarion's Board of Directors intends to continue the practice of
declaring cash dividends on a quarterly basis, no assurance can be given as to
future dividends or dividend rates since they will be determined in light of a
number of factors, including earnings, cash flow, and Aquarion and BHC's
financial requirements. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations - Capital Resources and Liquidity." Aquarion
paid dividends in 1990 and 1991 in excess of earnings, although there can be no
assurance that it would pay dividends in excess of earnings in the future.

                                NCC COMMON STOCK

  There is no established trading market for the Class A Common Stock or the
Class B Common Stock. The holders of Class A Common Stock are entitled to
receive prior to any payment of dividends to holders of Class B common Stock,
annual dividends in the amount of $1.00 per share of Class A Common Stock, when
and as declared by the Board of Directors of NCC. Holders of Class A Common
Stock are entitled to certain voting rights if dividends on such shares are in
arrears in excess of $2.00 per share. See "Comparison of the Rights of Aquarion
and NCC Shareholders." Although there can be no assurance that NCC would
continue to pay any dividends to holders of Class A Common Stock, the policy of
the Board is to pay sufficient dividends to maintain the dividend arrearages on
such shares to equal less than $2.00 per share. NCC has paid no dividends on the
Class B Common Stock since 1983, and, to the best knowledge of officers of NCC,
no dividends were paid on the Class B Common Stock prior thereto.

  NCC's Certificate of Incorporation provides that the holders of Class A Common
Stock are entitled to receive dividends from the net profits of NCC in priority
to any dividend on the Class B Common Stock. If, for any reason, dividends are
not declared on the outstanding Class A Common Stock, no dividend can be
declared on any Class B Common Stock. Furthermore, after paying the dividends on
the outstanding Class A Common Stock, the Class A Common Stock as a class, shall
be entitled to participate equally with the Class B Common Stock in the receipt
of any further dividends during any one year to the extent that the holders of
Class A Common Stock receive not more than an additional fifty cents per share.

  At September 30, 1994, there were 92 record holders of Class A Common Stock
and 74 record holders of Class B Common Stock.

                              PROPOSED TRANSACTION

BACKGROUND OF THE TRANSACTION

   Public water supply has been the core business of BHC since it was
established in 1857 and it remains a core business of BHC's parent company,
Aquarion. While BHC was formed originally to supply water to the City of
Bridgeport, its water supply business grew in Connecticut both through the
legislative expansion of its utility franchise into areas which were previously
not served by a public water supplier and also through acquisition of water
companies which served areas in close proximity to BHC's existing service areas,
such as the Westport Water Company and the Seymour Water Company. In 1984,

                                       18
<PAGE>
 
BHC acquired Stamford Water Company and shortly thereafter completed
negotiations with public water suppliers in lower Fairfield County, including
New Canaan Water Company, to construct a regional pipeline which made BHC's
water supply available to those suppliers. Since 1989, almost all water sold by
NCWC to its customers has been provided by BHC through the regional pipeline.
BHC's strategic objectives include the growth of its public water supply
business, and the opportunity to acquire NCWC, which is bordered by the service
areas of BHC and of Stamford Water Company and can therefore be operated
economically in conjunction with BHC's existing system, will further BHC's
attainment of those objectives. The acquisition of RWSC will also serve to
extend BHC's public water supply business into a new area.

   Water quality regulation became more complex and costly as a result of
amendments to the federal Safe Drinking Water Act in 1986. Water quality
standards for public drinking water and related testing and treatment
requirements demanded more operational expertise and capital investment by water
suppliers, and the costs of compliance with water quality regulations have
caused the rates charged for water to increase. Since the changes in the
regulations became effective both NCWC and RWSC have come under increasing
regulatory pressure to comply with a myriad of orders, regulations and laws,
many of which require considerable expenditures. Given the impact on rates,
economic regulators such as the DPUC have scrutinized both operational and
capital expenditures critically over the past several years. Given the weak
financial condition and limited customer base of NCC's subsidiaries and the
problems NCC has experienced in raising additional capital, attempts to resolve
these problems have proceeded at a pace unsatisfactory to NCC and the regulatory
agencies with jurisdiction over NCWC and RWSC. By contrast, BHC, serving
territories adjacent to those of NCWC and RWSC, is the largest investor-owned
water company operating in New England, and it has considerable financial
resources and an ability to attract additional equity capital.

   Mr. William S. Warner, then the President of BHC and Aquarion (then known as
The Hydraulic Company), first submitted a conceptual proposal regarding a
possible acquisition of NCWC to NCC in the spring of 1985, which proposal BHC
officers discussed with members of NCC's Board of Directors, including Messrs.
Alexander Boyle, Will Garey and Thomas Thomas over the course of several
meetings. However, the initial acquisition concept excluded RWSC and failed to
produce agreement with respect to the value of NCWC's real property. In
addition, uncertainties regarding the regulatory future of NCWC's real property,
including approximately 173 acres of real property with a reservoir located
thereon and certain related property, including the reservoir dam and
improvements and several water supply wells and easements, owned by NCWC and
situated in the Town of New Canaan, Connecticut (collectively, the "Reservoir"),
were unresolved. Various suggestions regarding a flexible pricing mechanism
which would have established a minimum acquisition price and a sharing of
proceeds from the sale of any such land, depending upon the amount of such
proceeds, were explored without reaching agreement. Discussion continued
sporadically through early 1988.

   In the summer of 1988, STD indicated its interest in acquiring the Reservoir
in order to meet its need for additional supply. Following discussions between
BHC and STD's General Manager, Mr. John S. Hiscock, BHC and STD agreed on the
terms of a joint proposal to purchase all of the assets of NCC whereby BHC would
acquire the transmission and distribution system of NCWC and STD would acquire
the Reservoir and related watershed property. RWSC as an asset of NCC was also
in the acquisition offer. STD's participation resolved questions pertaining to
the future use of the Reservoir and related watershed property of NCWC and
provided additional consideration which BHC would not have been willing to pay.

   With the compliance and capital needs of both NCWC and RWSC intensifying and
the resources of BHC and STD in mind, representatives of the managements of NCC
and its subsidiaries and of Aquarion and its subsidiaries and representatives of
STD met several times to discuss and negotiate the acquisition proposal. In
April, 1990 NCC and BHC signed a letter of intent whereby BHC would acquire all
the stock or assets of NCC. Negotiations were then undertaken by the parties
which resulted in the preparation and execution of the Acquisition Agreement and
the formulation of a Plan of Liquidation for NCC in September of 1992 and the
Property Exchange Agreement in October 1992.

   The Acquisition Agreement and the Property Exchange Agreement, if and when
performed, will result in NCWC and RWSC's becoming subsidiaries of BHC and
NCWC's acquiring improved commercial property, currently owned by MELP, in
exchange for water supply properties that are no longer required by it, and will
transform the ownership of NCC and its subsidiaries into an ownership interest
in Aquarion.

   Since the Acquisition Agreement and the Property Exchange Agreement were
executed in December, 1992, certain actions were required of the parties by
regulatory authorities. See "Proposed Acquisition -- Regulatory Approval." In
addition it has been necessary to amend both agreements on two occasions to
extend the date on which such agreements would

                                       19
<PAGE>
 
terminate if the closing had not occurred. Currently, the closing date must
occur on or before February 28, 1994 or the transactions will terminate by their
terms. It is unclear whether the DPUC will grant a further extension of the
closing date for these agreements.

NCC'S REASONS FOR THE TRANSACTION; RECOMMENDATION OF THE NCC BOARD OF DIRECTORS

   The NCC Board of Directors believes that the Acquisition, the Amendment and
the Liquidation should be approved by the NCC Shareholders in light of the
immediate and long-term capital needs of NCWC and RWSC and the favorable
exchange of investments that will be afforded the NCC Shareholders. The
Directors believe that BHC's strategic business plan to build a profitable,
expanding water supply business is consistent with the goals of NCWC and RWSC.
The Directors of NCC and the management of NCWC and RWSC, after careful study
and evaluation of the economic, financial and legal factors involved, believe
that the Acquisition will provide BHC with an increased opportunity for
expansion of its business, which in turn should benefit the NCC Shareholders who
become shareholders of Aquarion.

   The terms of the Acquisition Agreement and the Property Exchange Agreement
were the result of arms' length negotiations over an extended period of time.
Among the positive factors considered by the NCC Board in deciding to approve
and recommend the Acquisition and Liquidation Proposal were: the monetary terms
of the Acquisition Agreement and the Property Exchange Agreement, which
management of NCC and its subsidiaries believes constitute a fair price for the
assets of NCC; the financial condition, business assets and liabilities and
management of Aquarion and its subsidiaries; the financial and business
prospects of BHC and its subsidiaries as a result of their becoming a larger
combined operating entity, including the achievement of substantial economies of
scale; and that a market exists for the Aquarion Common Stock on the NYSE,
something that is lacking for NCC Common Stock.

   The NCC Board considers the Acquisition and Liquidation particularly
advantageous to NCC shareholders in that the NCC shareholders will receive a
security which, in the opinion of the NCC Directors, represents an investment of
the same character that has a potential to achieve a greater growth and market
value and that has significantly greater market liquidity than the NCC Common
Stock. The receipt of Aquarion shares as a result of the Acquisition and the
Liquidation is also intended to be a tax-free exchange, thereby affording NCC
shareholders an equity participation in Aquarion without currently incurring
federal income tax liability. See, "Federal Income Tax Consequences."

   The NCC Board made its determination without the assistance of a financial
advisor and without a "fairness opinion." The Directors believe that they
devoted a sufficient amount of time to assessing the advantages and
disadvantages of the Acquisition and the Plan of Liquidation.

THE NCC BOARD OF DIRECTORS HAS CONCLUDED THAT THE ACQUISITION AND LIQUIDATION
ARE IN THE BEST INTERESTS OF NCC AND ITS SHAREHOLDERS AND RECOMMENDS UNANIMOUSLY
THAT NCC SHAREHOLDERS APPROVE THE ACQUISITION AND THE LIQUIDATION AT THE
MEETING.

AQUARION'S AND BHC'S REASONS FOR THE TRANSACTION

    Aquarion's and BHC's respective Boards of Directors each believes that the
Acquisition represents an opportunity for BHC, in accordance with its strategic
business plan, to expand its public water supply business in the State of
Connecticut. The service areas of both NCWC and RWSC adjoin areas where BHC is
franchised to supply water, and most of NCWC's water supply is provided by BHC
through a regional pipeline. NCWC is also bordered by BHC's Stamford Water
Company ("SWC") subsidiary, which has a watershed extending into RWSC's service
area. Therefore, the ownership of contiguous transmission and distribution
systems would be united through the Acquisition, and the proximity of service
areas will enable BHC, either directly or through SWC, to supervise and
coordinate the operations of these companies with greater economy than could be
achieved through separate ownership. The Acquisition is therefore a natural
geographic fit which will expand Aquarion's core water supply business,
integrate water supply planning, and maximize opportunities for shared
efficiencies. The Aquarion and BHC Board each believes that the Acquisition will
contribute to the long-term stability of BHC as a regional water supplier.

    The Aquarion and BHC Board each also recognizes that STD's intended purchase
of the NCWC Reservoir, as set forth in the Property Exchange Agreement, is
advantageous to both BHC and the NCC Shareholders. BHC's willingness to acquire
NCWC and RWSC for the consideration specified in the Acquisition Agreement is
dependent upon STD's purchase of the NCWC Reservoir because, the receipt by
NCWC, when it is an Aquarion subsidiary, of the commercial building and

                                       20
<PAGE>
 
related land from MELP, as contemplated by the Property Exchange Agreement,
together with the acquisition of the assets of NCC justify the gross
consideration of $3.5 million and the assumption of $130,000 of debt to be paid
for the Acquisition. With STD's participation through the Property Exchange
Agreement, the Aquarion and BHC Boards consider that the net investment in the
remaining assets of NCWC and RWSC will be profitable in the long term. The Board
further believes that the willingness of STD and MELP to participate in the
Property Exchange, thereby enabling the tax liability associated with the gain
on the sale of the Reservoir to be deferred, is beneficial.

    Aquarion has not retained an outside party to evaluate the proposed
Acquisition but has instead relied upon the knowledge of its management in
utility regulation and ratemaking in Connecticut in considering the financial
viability of the Acquisition. Appraisals obtained for regulatory purposes in
1991 valued the Reservoir property to be transferred to STD at $2,264,000 and
the MELP building at $2,000,000. The MELP appraisal placed primary emphasis on
the sales comparison method of valuation but also indicated a value in excess of
$2,400,000 using the cost approach to valuation. Neither the Aquarion Board nor
the BHC Board based their approval of the Acquisition on a comparison of
appraisals but instead have determined that the difference in appraised values
of the Reservoir and the MELP building is not material over the long term and is
justified by the overall benefit of the Acquisition to Aquarion and BHC,
including the net cost of the water supply system after the property exchange
has taken place and the benefit of the deferral of tax consequences on the
property exchange transaction.

                              PROPOSED ACQUISITION

ACQUISITION AGREEMENT - PRINCIPAL PROVISIONS

   A copy of the Acquisition Agreement is annexed as Exhibit __ to this
Prospectus/Proxy Statement and is incorporated herein by reference. The
description of the contents that follows is necessarily incomplete; and
reference is made to the exhibited Acquisition Agreement itself for a complete
description of each matter and of all of the terms and conditions of the
Acquisition.

   NCC, Aquarion and BHC entered into the Acquisition Agreement on September 2,
1992. It and its subsequent amendments provide (i) for the sale by NCC of all of
its assets, which consist of all of the outstanding Common Stock, $25 par value,
of NCWC and 97.2% of the outstanding Common Stock, $25 par value, of RWSC to BHC
for (a) an assumption of NCC's obligation to repay borrowings from Charles
Perkins in an amount not to exceed $130,000 plus (b) $3,500,000, subject to
reduction for the payment of certain other indebtedness of NCC and certain
transaction costs (as adjusted, the Purchase Price), (ii) for payment of the
Purchase Price by delivery to NCC of newly-issued Aquarion Common Stock having
an aggregate value, calculated in accordance with the Acquisition Agreement,
equal to the Purchase Price, (iii) that the value of a share of Aquarion Common
Stock will be deemed to be the average of the daily closing prices of Aquarion's
Common Stock, as reported on the composite tape for NYSE listed securities, for
the 30 consecutive business days commencing with the 45th business day prior to
the closing date of the transaction, and (iv) for the deposit of 10% of the
shares of Aquarion Common Stock issued and delivered in payment of the Purchase
Price into an escrow account (described below) to be applied to satisfy
obligations of NCC to indemnify BHC for losses arising out of breaches of the
Acquisition Agreement terms and provisions and/or undisclosed liabilities of
NCC. The amount of $3,500,000 will be reduced by (i) any amount by which NCC's
obligation to Mr. Perkins exceeds $130,000, (ii) any liability of NCWC to NCC or
Ms. Anne Romo for borrowed money, (iii) any unsecured liability of NCWC to
CityTrust for borrowed money, (iv) any liability of RWSC to NCC for borrowed
money, all determined as of the Closing Date. The DPUC in its decision approving
the Acquisition Agreement and the Property Exchange Agreement modified the terms
and conditions of the Acquisition Agreement. Pursuant to the DPUC decision, NCC
or its subsidiaries must repay certain obligations, which at the time of the
DPUC decision equalled approximately $308,000 to suppliers, shareholders and
lending institutions and if they are unable to do so prior to the Closing Date,
BHC shall pay the balance of such obligations on behalf of NCC and the amount of
$3,500,000 shall be reduced accordingly.

   It is currently estimated that at September 30, 1994 the $3,500,000 would
have been reduced by approximately $750,000. Such $750,000 consists of (i)
approximately $300,000 of legal fees, accountants' fees and other transaction
related expenses for which NCC is liable, which liabilities will be assumed and
paid by BHC; (ii) a payment of $105,000 agreed to be made by NCC to Mr. McLinden
in respect of his role in negotiating the Acquisition, which liability will be
assumed and paid by BHC; (iii) approximately $168,000 of liabilities of NCC and
its subsidiaries to certain of NCC's shareholders, which will be assumed and
paid by BHC at the Closing; and (iv) approximately $177,000, representing the
estimated amount of certain other liabilities of NCWC and RWSC. In addition, the
expenses of the administration of the escrow fund, the liquidation of NCC and
payments, if any, to Dissenting Shareholders will be paid by liquidating
Aquarion shares received

                                       21
<PAGE>
 
as Purchase Price and will reduce the number of shares of Aquarion Common Stock
received by holders of Class B Common Stock in the Liquidation.

   The Closing Date will be the earliest practicable date following approval of
the Acquisition, the Amendment and the Liquidation by the requisite votes of the
holders of NCC Common Stock and the receipt of all requisite regulatory
approvals of the Acquisition Agreement and the Property Exchange Agreement.
Unless extended by BHC and NCC, the Acquisition Agreement will automatically
terminate if the Closing Date has not occurred on or before February 28, 1995.

OTHER ACQUISITION AGREEMENT PROVISIONS

   In the Acquisition Agreement, NCC has represented and warranted that it is a
duly organized and validly existing corporation in good standing, with all
requisite power and authority to own its assets and carry on its business; that
NCWC and RWSC have rights to use the water they are using for water supply; that
the descriptions of the facilities of NCWC and RWSC given to BHC are accurate in
all material respects; that neither NCWC nor RWSC are charging more for sales of
water than the rates approved by the DPUC; that, except for requisite regulatory

   In the Acquisition Agreement, NCC and BHC have covenanted with one another to
exchange information relative to their respective representations and
warranties; to take all actions necessary to satisfy the conditions to, and
consummate, the Acquisition to take no action inconsistent with their respective
obligations under the Acquisition Agreement; and to establish the escrow account
(described below). In addition, NCC has covenanted that, pending the Acquisition
Closing, neither NCWC nor RWSC will make any capital expenditure in excess of
$1,000, or any expenditures aggregating more than $25,000 without BHC's
approval.

   BHC has covenanted, in the Acquisition Agreement, to indemnify and hold
harmless NCC and its affiliates, and its and their respective employees,
representatives, officers, directors and agents from any losses resulting from
any misrepresentation by BHC in the Acquisition Agreement, any breach by BHC of
any provision of the Acquisition Agreement and any claims, legal actions or
proceedings related to actions taken by BHC relative to the Acquisition
Agreement. Aquarion has agreed to indemnify and hold harmless NCC and each
person controlling NCC against any losses experienced by it or such person
arising out of any claim based on an allegation that Aquarion's Registration
Statement, including this Prospectus/Proxy Statement, contains an untrue
statement of any material fact or omits to state a material fact, except insofar
as any such claim is based on written information furnished to Aquarion by NCC,
NCWC or RWSC or the failure of NCC to have furnished to Aquarion and BHC a true
and accurate list of NCC shareholders with valid and current addresses of such
shareholders.

   NCC has agreed, in the Acquisition Agreement, on behalf of itself and the NCC
shareholders, that NCC and, after its liquidation pursuant to the Plan of
Liquidation, the NCC shareholders, will indemnify and hold harmless BHC and its
affiliates, and its and their respective employees, representatives, officers,
directors and agents from any losses resulting from any misrepresentation by NCC
in the Acquisition Agreement, any breach by NCC of any provision of the
Acquisition Agreement, any claims, legal actions or proceedings related to
actions taken by NCC, NCWC or RWSC relative to the Acquisition Agreement, any
liability or obligation not assumed by BHC under the Acquisition Agreement
related to any

                                       22
<PAGE>
 
transaction or time period prior to the Acquisition Closing, or any
misinformation furnished to, or failure to furnish information to, Aquarion for
use in the preparation of its Registration Statement. The liability of each NCC
Shareholder pursuant to this indemnification commitment made on his, her or its
behalf in the Acquisition Agreement is limited to the amount of the assets of
NCC (which will consist of shares of Aquarion Common Stock) received by such
shareholder under the Plan of Liquidation.

ACQUISITION AGREEMENT - ESCROW ACCOUNT

   An escrow account will be established at the Acquisition Closing, into which
NCC will deposit 10% (the "Escrow Shares") of the shares of Aquarion Common
Stock received by NCC in payment of the Purchase Price. This Escrow Account will
be used to pay indemnification obligations of NCC described in the preceding
paragraph that become payable within one year after the Closing Date; and the
balance remaining in the escrow account on the first anniversary of the Closing
Date will be paid over to NCC for distribution to the holders of the Class B
Common Stock under the Plan of Liquidation, except that a number of shares of
Aquarion Common Stock with an aggregate value sufficient to satisfy any unpaid
judgment or settlement and any outstanding or unsatisfied claims against the
Escrow Account will be retained therein until all such judgments, settlements
and claims have been satisfied and discharged and thereafter Escrow Shares not
utilized for the foregoing purposes will be distributed to the former holders of
the Class B Common Stock. The right to receive shares of Acquiror Common Stock
from the escrow account will not be transferable by the former holders of Class
B Common Stock.

CONDITIONS TO CLOSING ON THE ACQUISITION AGREEMENT TRANSACTIONS

   In addition to approval of the Acquisition, the Amendment and the Liquidation
by the NCC shareholders at the Special Meeting, and to the regulatory approvals
(see "Regulatory Approvals"), the respective obligations of NCC, Aquarion and
BHC to consummate the Acquisition Closing are subject to the satisfaction or
waiver of other conditions, including: (i) the accuracy in all material respects
of the representations and warranties made by the parties in the Acquisition
Agreement; (ii) the performance by the parties of their respective obligations
under the Acquisition Agreement prior to the Closing Date; (iii) the absence of
any material adverse change in the business, operations, properties, condition
(financial or otherwise) or prospects of NCC, NCWC or RWSC; (iv) the binding and
unconditional status of the obligations of the parties to and under the Property
Exchange Agreement (which requires satisfaction of the conditions described
below under "Conditions to Closing on the Property Exchange Agreement"); (v)
receipt of an environmental assessment satisfactory to BHC of the businesses of
NCC, NCWC and RWSC; (vi) the effectiveness of the Aquarion Registration
Statement under the Securities Act with respect to the shares of the Aquarion
Common Stock to be issued pursuant to the Acquisition Agreement; (vii) the
absence of any action or proceeding enjoining the Acquisition Agreement
transactions; (viii) the absence of any action or proceeding by any governmental
agency that might result in substantial damages in respect of said transactions
or enjoining the consummation of said transactions; (ix) a requirement that no
more than 140,000 or less than 87,500 shares of Aquarion Common Stock be issued
to NCC; (x) the receipt of an opinion satisfactory to NCC from tax counsel
relating to the Plan of Liquidation; and (xi) the satisfaction of the Board of
Directors of BHC and the Board of Directors of NCC with the regulatory treatment
afforded the transactions by the DPUC.

TERMINATION OR AMENDMENT OF THE ACQUISITION AGREEMENT

   The Acquisition Agreement may be terminated or amended by mutual agreement of
the Boards of Directors of NCC and BHC, or terminated by the Board of Directors
of NCC or BHC in the event that the Acquisition Closing does not occur on or
before February 28, 1995. The Acquisition Agreement can be amended only by
agreement among the Boards of Directors of NCC, BHC and Aquarion.

PROPERTY EXCHANGE AGREEMENT--PRINCIPAL PROVISIONS

   A copy of the Property Exchange Agreement and the Amendment thereto are
annexed as Exhibits D and E to this Prospectus/Proxy Statement and is
incorporated herein by reference. The description of its contents that follows
is necessarily incomplete; and reference is made to the exhibited Property
Exchange Agreement itself for a complete description of each matter and of all
of the terms and conditions of the Property Exchange.

   NCWC, Aquarion, MELP and STD entered into the Property Exchange Agreement on
October 21, 1992. In it, the parties agree to a three-cornered property exchange
(the "Property Exchange") whereby (i) MELP will transfer to NCWC a three-acre

                                       23
<PAGE>
 
parcel of real property and a commercial building thereon situated in the Town
of Monroe, Connecticut (the "Building Property"), (ii) NCWC will transfer to STD
title to the Reservoir, (iii) STD will pay $2,200,000 to MELP, and (iv) Aquarion
will pay $285,000 to MELP ($72,000 of which was deposited by Aquarion with MELP
at the time of execution of the Property Exchange Agreement). The amount of
$285,000 will be increased by the rate of inflation to the Property Exchange
Closing. The Property Exchange Closing will occur after the Acquisition Closing,
and the latter is conditioned on the Property Exchange Agreement's being
unconditionally binding on the parties thereto. At the Property Exchange
Closing, taxes, water and sewage use charges and other costs, charges and
expenses associated with the Building Property and the Reservoir will be
apportioned among MELP, NCWC and STD on the customary chronological basis, the
transferring entities (MELP and NCWC) will be responsible for the payment of
conveyance taxes on the property each is transferring, and the transferee
entities (NCWC and STD) will bear the costs of title examination and title
insurance on the property each will receive.

   In the Property Exchange Agreement, NCWC has represented that it is a duly
organized and validly existing public service company in good standing, with all
requisite power and authority to own and convey the Reservoir and to carry on
its business; that it has rights to use the water it is using for water supply;
that the descriptions of its facilities given to the other parties are accurate
in all material respects; that, except for requisite regulatory approvals, no
third-party approvals or consents are required for the performance of its
obligations under the Property Exchange Agreement; that no pending or threatened
litigation or other legal proceeding exists that would impair the performance by
it of its obligations under the Property Exchange Agreement; that it has
operated the Reservoir in accordance with all applicable environmental and other
laws and regulations; and that it has good, marketable and insurable title to
the Reservoir.

   MELP has represented, in the Property Exchange Agreement, that it is a duly
organized and validly existing general partnership with all requisite power to
own and convey the Building Property and to carry on its business; that no
third-party approvals or consents are required for the performance by it of its
obligations under the Property Exchange Agreement; that no pending or threatened
litigation or other legal proceeding exists that would impair its ability to
perform its obligations under the Property Exchange Agreement; that it has
operated the Building Property in compliance with all environmental, zoning and
other governmental laws and regulations; that it has good, marketable and fully
insurable title to the Building Property; and that neither MELP nor any of its
partners has any knowledge of any proposed, pending or threatened event that
would adversely affect the use or value of the Building Property.

   STD has represented and warranted, in the Property Exchange Agreement, that
it is a municipal corporation duly organized and validly existing in good
standing, with all requisite power and authority to own its assets and carry on
its business; that except for requisite regulatory approvals, no third-party
approvals or consents are required for the performance by it of its obligations
under the Property Exchange Agreement; and that no pending or threatened
litigation or other legal proceeding exists that would impair its ability to
perform its obligations under the Property Exchange Agreement.

   The parties to the Property Exchange Agreement have covenanted with one
another to exchange information relative to their respective representations and
warranties, to permit inspection of the properties to be transferred, and to
take all actions necessary to satisfy the conditions to, and consummate, the
Property Exchange Closing. In addition, MELP and NCWC have covenanted to
maintain and manage the Building Property and the Reservoir, respectively, in
accordance with good business practice and all applicable laws and regulations;
and Aquarion and STD have covenanted to inspect the Building Property and the
Reservoir, respectively.

CONDITIONS TO CLOSING ON THE PROPERTY EXCHANGE AGREEMENT TRANSACTIONS

   In addition to the regulatory approvals described below at "Regulatory
Approvals," the respective obligations of NCWC, Aquarion, MELP and STD to
consummate the Property Exchange Closing are subject to the satisfaction or
waiver of several conditions, including: (i) the accuracy in all material
respects of the representations and warranties made by the parties in the
Property Exchange Agreement; (ii) the performance by the parties of their
respective obligations under the Property Exchange Agreement prior to the
Closing Date; (iii) the absence of any action or proceeding enjoining the
Property Exchange; and (iv) the absence of any action or proceeding by any
governmental agency that might result in substantial damages in respect of the
Property Exchange or enjoining the consummation of the Property Exchange. In
addition, the obligations of NCWC and Aquarion are subject to: (v) the receipt
of an environmental assessment of the Building Property indicating that no
material change in the condition of the building has occurred since tests
conducted in 1990; (vi) receipt of permission from the Town of New Canaan to
extend a water supply pipeline, for and on behalf of and at the expense of STD,
from the NCWC water supply transmission system to the boundary between the Towns
of New Canaan and Wilton, Connecticut; (vii) development, at the expense of STD,
of an alternate means of supplying water to all existing customers of NCWC on a
water supply main 

                                       24
<PAGE>
 
that will be used by STD as a raw water supply main subsequent to the Property
Exchange Closing; (viii) completion of the Acquisition Closing; and (ix) DPUC
treatment, for rate-making purposes, of the assets and related expenses of NCWC
and RWSC after the Acquisition Closing and the Property Exchange Closing
satisfactory to NCWC and BHC. In addition, the obligations of STD are subject
to: (x) receipt of a satisfactory environmental assessment of the Reservoir;
(xi) receipt of an inspection report indicating that the condition of the dam at
the Reservoir is as specified in a report prepared in 1985; (xii) receipt of
easements required for the installation of a gravity water supply main from the
Reservoir that will avoid a topographic elevation in the Town of New Canaan; and
(xiii) receipt of easements for an emergency spillway at and from the Reservoir
across property owned by NCWC to the Five Mile River, which spillway, together
with other estimated costs of river channel improvements, will not exceed
$200,000. It is anticipated that the conditions described in (v) through (xii)
will either be obtained or waived by January 31, 1995 and the condition in
(xiii) will be satisfied by the Closing Date.

TERMINATION OR AMENDMENT OF THE PROPERTY EXCHANGE AGREEMENT

   The Property Exchange Agreement may be terminated if the Acquisition
Agreement is terminated, if the Acquisition Closing does not occur, if the
Property Exchange Closing does not occur on or before February 28, 1995 or by
mutual written consent of MELP, STD, NCWC and Aquarion. The Property Exchange
Agreement can be amended only by agreement among MELP, STD, NCWC and Aquarion.

EXPENSES AND LIABILITY FOR TERMINATION OF THE ACQUISITION AGREEMENT AND THE
PROPERTY EXCHANGE AGREEMENT

   All of the parties to each of the Acquisition Agreement and the Property
Exchange Agreement have agreed to pay their own respective costs and expenses
(including all professional and other fees) relating to such agreement, the
negotiations therefor and the transactions contemplated thereby. All of the
parties to each of said agreements have also agreed that, in the event of the
termination of such agreement, all obligations of all of the parties will
terminate and no party will have any obligation or liability to any of the other
parties with respect to any breach of such agreement, regardless of whether such
breach is outstanding or curable at the date of termination of the agreement.

REGULATORY APPROVALS

   In addition to approval of the Acquisition and Plan of Liquidation by the
Shareholders of NCC, and to the satisfaction of the conditions described above
to the Acquisition Closing and Property Exchange Closing, the consummation of
the Acquisition is subject to obtaining the approvals of several state
regulatory agencies. The DPUC must approve the transfer to BHC of a controlling
interest in the stock of NCWC and RWSC, as well as the transfer of the Reservoir
from NCWC to STD. By application to the DPUC filed on June 27, 1991 and by
Supplement to Application filed on September 19, 1991, NCWC, RWSC, NCC,
Aquarion, STD and MELP requested that the DPUC approve the Acquisition
Agreement, the Property Exchange Agreement, and certain other related matters.
On or about the same time STD filed an application with the DEP for approval of
a diversion permit relating to the transfer of the Reservoir from NCWC to STD
pursuant to the Property Exchange Agreement. STD, NCWC and BHC also applied to
the DPHAS to formally approve the transfer of such reservoir.

   After several hearings and submission of requested and required documents,
the DPUC, on June 17, 1993, issued its preliminary decision, and on June 30,
1993 the DPUC issued its final decision approving the Acquisition Agreement and
Property Exchange Agreement (the "DPUC Decision"). The DPUC Decision placed
certain conditions on the Acquisition which differed from the terms and
conditions of the Acquisition Agreement and Property Exchange Agreement.
Specifically, the DPUC ordered NCC or its subsidiaries to repay $308,000 in
amounts owed to suppliers, shareholders or lending institutions prior to the
Closing. If NCC is unable to do so, BHC is to pay the amounts owed at Closing
and reduce the Purchase Price by a corresponding amount. As of September 30,
1994, $287,000 of such $308,000 had been paid by NCC's subsidiaries.

   The DPUC subsequently reopened its approval proceeding to consider the
potential impact of a proposed NCWC land sale on NCWC's ability to retire an
existing $1.25 million loan from Village Bank & Trust Company and appropriate
regulatory treatment of any shortfall between the net proceeds from such a sale
and the amount of the debt and to consider certain anticipated costs associated
with reregistration of RWSC supply sources. No final decision has yet been
issued in the reopened proceeding. BHC and NCC have agreed that the Acquisition
will close whether or not the sale of land by NCWC and the retirement of NCWC
debt takes place. However, the effect on the acquisition of any other terms and
provisions of a DPUC approval, not contemplated by the agreement between BHC and
NCC, cannot be predicted.

                                       25
<PAGE>
 
   The transfer of the Reservoir to STD as a raw drinking water supply source
must be approved by the DPHAS, before which a permit application is pending. It
is expected that the permit will be issued upon submission of final information
regarding ownership of watershed and non-watershed land after the proposed
transfer takes place. A diversion permit from the DEP is required in order for
STD to use water from the NCWC Reservoir in STD's system. The DEP issued a
diversion permit satisfactory to STD and to a group of area residents in July,
1994, but two local residents petitioned the DEP to issue a declaratory ruling
to the effect that the permit should not have been issued without a public
hearing. The DEP denied the petition, but it is possible that the petitioners
will seek judicial review of the DEP's ruling. STD has indicated that it will
proceed with the Property Exchange Closing notwithstanding the existence of
judicial or regulatory challenge to the issuance by the DEP of the diversion
permit.

RESALE OF AQUARION COMMON STOCK

   The Aquarion Common Stock to be issued pursuant to the Acquisition will be
freely transferable after four months, except that shares issued to any NCC
shareholder who may be deemed to be an "affiliate" (as defined under the
Securities Act of 1933, as amended (the "Securities Act") of NCC for purposes of
Rule 145 under the Securities Act shall not be transferable except in compliance
with the Securities Act. This Joint Proxy Statement/Prospectus does not cover
resales of Aquarion Common Stock received by any person who may be deemed to be
an affiliate of NCC. The Acquisition Agreement provides that shares of Aquarion
Common Stock distributed to NCC shareholders may not be sold for a period of
four months from the Acquisition Closing Date.

ACCOUNTING TREATMENT OF THE TRANSACTION

   The Acquisition is expected to qualify as a "pooling of interests" for
accounting and financial reporting purposes. Under this method of accounting,
the recorded assets and liabilities of NCC will be carried forward to Aquarion
at their recorded amounts and income of Aquarion will include income of NCC for
the entire fiscal year in which the Acquisition occurs.

CERTAIN TRANSACTIONS BETWEEN AQUARION AND NCC

    In addition to the Acquisition Agreement and the Property Exchange
Agreement, and amendments thereto which increased the gross consideration for
the Acquisition from $3.25 million to $3.5 million and extended the closing
deadline for the transactions contemplated thereby, BHC, NCWC and RWSC have,
pursuant to DPUC order, submitted a proposed Management Consulting Agreement
(the "Management Agreement") to the DPUC and await the DPUC's formal approval
before executing it. The Management Agreement, which the DPUC representatives
have stated should be considered effective as of November 1, 1994, provides that
certain management services be available to NCWC and RWSC from a BHC affiliate,
Aquarion Management Services Company ("AMS"). NCWC and RWSC have been directed
by the DPUC not to make certain operational decisions or financial commitments
without consulting with AMS. The Management Agreement expires upon the earlier
of the date of the Acquisition or on March 31, 1995. Consideration payable to
AMS under the Management Agreement is based on hourly rates plus expenses for
AMS personnel which have been submitted to the DPUC.

    NCWC and BHC are parties to an agreement which enables NCWC to purchase one
million gallons of treated water a day from BHC through a regional pipeline
which connects NCWC's distribution system with BHC's water supply. NCWC obtains
most of the water it distributes and sells to its customers from BHC pursuant to
this agreement, to which other water utilities in southwestern Fairfield County
are also parties. The price paid by utilities for water from the pipeline is
based on a formula which reflects BHC's costs in providing the water. The
agreement first became effective in 1984 and is subject to negotiation of price
terms and water allocations every five years and a related DEP water diversion
permit from the Connecticut Department of Environmental Protection is subject to
renewal in 1995.

                              PLAN OF LIQUIDATION

PROVISIONS OF PLAN OF LIQUIDATION

   A copy of the Plan of Liquidation is annexed as Exhibit F to this
Prospectus/Proxy Statement and is incorporated herein by reference. The Plan of
Liquidation provides that, upon consummation of the Acquisition and the filing
of the Amendment with the Secretary of State of the State of Connecticut, NCC
will be dissolved pursuant to the provisions of the CSCA. Following the
procedures prescribed in the CSCA, the NCC Board will file with the Secretary of
the State of Connecticut 

                                       26
<PAGE>
 
a Certificate of Dissolution, thereby terminating the corporate existence of
NCC. The NCC Board will, however, continue to function with authority to wind up
NCC's affairs, pay, satisfy and discharge its liabilities and obligations,
obtain all required clearances from governmental tax and other authorities, and
distribute to the NCC shareholders all of its remaining assets. It is
anticipated that these assets will consist solely of shares of Aquarion Common
Stock, the number of which will be determined as described at "Proposed
Acquisition - Acquisition Agreement - Principal Provisions" above and cannot be
predicted accurately at this time. Although the Certificate of Incorporation of
NCC provides that, on liquidation, the holders of NCC Class A Common Stock will
receive cash in the amount of $35 per share plus accrued but unpaid dividends,
the Amendment would amend NCC's Certificate of Incorporation to provide that the
amount payable to holders of Class A Common Stock may be paid in cash or in
other property. Pursuant to the terms of the Plan of Liquidation and the
Amendment, holders of Class A Common Stock will receive, for each share of Class
A Common Stock, shares of Aquarion Common stock with a value (determined in
accordance with the terms of the Acquisition Agreement) on the Closing Date
equal to $35.00 plus all accrued but unpaid dividends on the Class A Common
Stock to the date of liquidation. Ten percent of the shares of Aquarion Common
Stock issued as payment of the Purchase Price shall be paid by NCC to the escrow
agent for the Escrow Fund, which shares will be withheld from the distribution
payable to the holders of Class B Common Stock. All of the directors who are
shareholders of NCC have indicated that they intend to vote for the Plan of
Liquidation in their capacity as shareholders. The balance of the shares shall
be paid to the holders of the Class B Common Stock, pro rata based on each such
holders ownership interest in such shares immediately prior to the Liquidation.
In addition, the expenses of the administration of the escrow fund, and the
liquidation of NCC and payments, if any, to Dissenting Shareholders will be paid
by liquidating Aquarion shares received as Purchase Price and will reduce the
number of shares of Aquarion Common Stock received by holders of Class B Common
Stock. Escrow Shares not applied to indemnification obligations will be
distributed to the former holders of the Class B Common Stock in accordance with
the Escrow Agreement after the termination thereof.

FRACTIONAL SHARES

   If the foregoing distribution calculation does not result in a shareholder of
NCC being entitled to a whole number of shares of Aquarion Common Stock, the NCC
shareholder will receive a cash payment in lieu of any entitlement to a
fractional share of Aquarion Common Stock from the proceeds of a sale on the
NYSE by NCC of a sufficient number of shares of Aquarion Common Stock to settle
the aggregate amount of fractional share distribution entitlements of all
similarly situated shareholders of NCC. As a result, no fractional shares of
Aquarion Common Stock will be distributed under the Plan of Liquidation.

RECEIPT OF AQUARION SHARES

   It is anticipated that the shares of Aquarion Common Stock remaining
available for NCC's liquidation distribution after payment, satisfaction and
discharge of all of NCC's liabilities and obligations, and the costs of
liquidation, will be distributed to the shareholders of NCC in an initial
distribution. Although this initial distribution will be made on the earliest
practicable date following the Acquisition Closing and the dissolution of NCC,
the amount of time that will be required to wind up NCC's affairs, pay, satisfy
and discharge or make adequate provisions for all of its liabilities and
obligations and obtain all required governmental clearances cannot be predicted
accurately. It is presently estimated that the initial liquidation distribution
will occur on or about four months following the Acquisition Closing and
dissolution of NCC. The remaining Aquarion Shares will be distributed as soon as
practicable after the initial distribution.

   As described above at "Proposed Acquisition - Acquisition Agreement - Escrow
Account," 10% of the shares of Aquarion Common Stock received by NCC at the
Acquisition Closing as the Purchase Price will be deposited in an Escrow Account
for the satisfaction of certain NCC indemnification obligations. On the closing
of this Escrow Account, which will occur no later than the first anniversary of
the Acquisition Closing Date, any shares of Aquarion Common Stock remaining in
the Escrow Account will be distributed by the NCC Board in a final liquidating
distribution to the former holders of NCC Class B Common Stock in the
proportional manner described above.

                AMENDMENT TO NCC'S CERTIFICATE OF INCORPORATION

   The Certificate of Incorporation of NCC currently provides that in the event
of a voluntary liquidation or dissolution of NCC, the holders of the Class A
Common Stock are entitled to receive $35.00 per share plus accrued but unpaid
dividends to the date of liquidation or dissolution. After the holders of the
Class A Common Stock are paid in full, the remaining assets shall be paid to the
holders of the Class B Common Stock, ratably in accordance with their respective
shareholdings.

   NCC wishes to amend the Certificate of Incorporation to provide that the
liquidation preference payable to the holders of Class A Common Stock may be
paid in cash or in other property. Because the Acquisition provides for the
payment of the Purchase Price in shares of Aquarion Common Stock which will then
be distributed to the shareholders of NCC in the liquidation, NCC will
distribute stock and not cash in the liquidation. The amendment is meant to make
clear that such a distribution is permitted under NCC's charter.

   The text of the Amendment is attached hereto as Exhibit G, and reference is
made thereto for the actual text to be included in the Certificate of
Incorporation. The Board of Directors of NCC approved the Amendment at a meeting
of the Board of Directors held on December 17, 1994. All of the directors who
are also shareholders have indicated that they intend to vote for the Amendment
in their capacity as shareholders of NCC.

              FEDERAL INCOME TAX CONSEQUENCES OF THE ACQUISITION,
                       PROPERTY EXCHANGE AND LIQUIDATION

   The following description summarizes the principal federal income tax
consequences that may be expected to result from the Acquisition, Property
Exchange and Liquidation.

   NCC will be excused from performing its obligations under the Acquisition
Agreement unless it has received an opinion of Haythe & Curley, of New York, New
York, its tax counsel, to the effect that the transaction will constitute a
reorganization within the meaning of Section 368(a)(1)(C) of the Internal
Revenue Code of 1986 (the "Code"). This opinion will be based on certain
assumptions and representations of the parties to the transaction, including
that: (i) NCC will transfer to BHC at least 90% of the fair market value of
NCC's net assets, and at least 70% of the fair market value of NCC's gross
assets, determined immediately prior to the Acquisition Closing; (ii) NCC will
distribute the Aquarion Common Stock received in payment of the Acquisition
Price to NCC's Shareholders (and any creditors) in complete liquidation of NCC
within a reasonable period of time following the Acquisition Closing; (iii) on
the Closing Date, NCC's Shareholders will have no present intention to sell or
dispose of the Aquarion Common Stock received in liquidation of NCC such that,
in the aggregate, the NCC shareholders' ownership of Aquarion Common Stock will
be reduced to a number of shares having a value of less than 50% of the value of
the outstanding NCC Common Stock as of the Closing Date; (iv) the fair market
value of the Aquarion Common Stock received by each NCC Shareholder will be
approximately equal to the fair market value of such shareholder's NCC Common
Stock surrendered in liquidation; (v) the fair market value of the NCC assets
transferred to BHC in the Acquisition will exceed the sum of all liabilities
assumed by BHC under the Acquisition Agreement; (vi) the only consideration
received by NCC under the Acquisition Agreement will consist of shares of
Aquarion Common Stock, cash in lieu of any fractional share of such stock and
the assumption by BHC of certain liabilities of NCC; (vii) on the Closing Date,
BHC will have no present intention of selling or disposing of any of the assets
of NCC purchased at the Acquisition Closing, other than in the ordinary course
of business; and (viii) following the Acquisition Closing, BHC will continue the
historic businesses of NCWC and RWSC which are the regulated utility business of
public water supply.

   If the transaction is treated as a reorganization under Section 368(a)(1)(C)
of the Code, generally, no gain or loss will be recognized for federal income
tax purposes by NCC, BHC or Aquarion as a result of the transaction. To the
extent, if any, that NCC is deemed to be in receipt of non-qualified
consideration by reason of the payment of its costs or otherwise, NCC may be
required to recognize a portion of its gain on the transaction. The federal
income tax basis of the stock of NCWC and the stock of RWSC in the hands of BHC
immediately after the consummation of the transaction will be the same as the
basis of those assets in NCC's hands immediately prior to the consummation of
the transaction; and the holding period of these stock assets in BHC's hands
immediately after the consummation of the transaction will include the holding
period of such stock in NCC's hands immediately prior to the consummation of the
transaction.

   If the transaction is treated as a reorganization under Section 368(a)(1)(C)
of the Code, each NCC shareholder who, pursuant to the Plan of Liquidation,
receives a distribution of Aquarion Common Stock in liquidation of NCC will not
recognize any federal income tax gain or loss on such distribution. The federal
income tax basis of the Aquarion Common Stock received by such NCC Shareholder
in the liquidation distribution from NCC will be equal to the tax basis of the

                                       28
<PAGE>
 
shareholder's NCC Common Stock surrendered by the shareholder in NCC's
liquidation; and, if the shares of NCC Common Stock have been held by the
shareholder as capital assets, the federal income tax holding period of the
Aquarion Common Stock received by the shareholder in the NCC liquidation will
include the holding period of the surrendered NCC Common Stock in the
shareholder's hands.

   Any cash received by an NCC shareholder in lieu of a fractional share of
Aquarion Common Stock in liquidation of such shareholder's stock ownership in
NCC will be treated as a distribution in full payment for a proportional
fractional interest of the shareholder's NCC Common Stock ownership prior to the
NCC liquidation; and federal income tax gain or loss will be recognized by the
shareholder, measured by the difference between the amount of cash received and
the shareholder's adjusted basis for the proportional fractional NCC Common
Stock ownership.

   Any NCC shareholder who exercises his, her or its right to dissent from the
Transaction and to receive from NCC the fair market value of such shareholder's
NCC Common Stock in cash will be treated for federal income tax purposes as
receiving the cash in full payment for the liquidation of the shareholder's NCC
Common Stock holding. The shareholder will recognize gain or loss for federal
income tax purposes, upon receipt of the cash payment, measured by the
difference between the amount of cash received and the shareholder's adjusted
basis in the NCC Common Stock surrendered in the NCC liquidation. If the NCC
Common Stock surrendered in the NCC liquidation was held as a capital asset by
the shareholder, the gain or loss will be a capital gain or loss for federal
income tax purposes.

   The Property Exchange under the Property Exchange Agreement is intended to
qualify, for federal income tax purposes, as a tax-free like-kind exchange under
Section 1031 of the Code. A ruling from the Internal Revenue Service concerning
the tax consequences of the Property Exchange has not been requested, nor will
an opinion of tax counsel be obtained by any party to the Property Exchange
Agreement. Section 1031(a)(1) of the Code provides that no gain or loss for
federal income tax purposes will be recognized on the exchange of property held
for productive use in a trade or business or for investment if the property is
exchanged solely for property of a like kind which is to be held after the
exchange either for productive use in a trade or business or for investment.
Real property is generally considered to be of a like kind to all other real
property, whether or not the property is improved or unimproved. It is
anticipated that the Building Property and the Reservoir will be treated as
like-kind property and that the Property Exchange will qualify for non-
recognition of gain or loss under Section 1031 of the Code. If the Property
Exchange so qualifies, no gain or loss for federal income tax purposes will be
recognized by NCWC as a result of its acquisition of the Building Property in
exchange for the Reservoir; and the tax basis of the Building Property in NCWC's
hands will be the same as its tax basis for the Reservoir, increased by the
amount of $200,000 cash paid to MELP by Aquarion as a part of the Property
Exchange transaction. The holding period of the Building Property in NCWC's
hands for federal income tax purposes will include the holding period of the
Reservoir in its hands prior to the Property Exchange Closing.

   If the Internal Revenue Service were to challenge successfully the
qualification of the Property Exchange for non-recognition of gain under Section
1031 of the Code, the Property Exchange would result in the recognition of gain
by NCWC to the extent of the difference between the fair market value of the
Reservoir on the date of the Property Exchange and NCWC's adjusted basis in the
Reservoir. In such event, NCWC's tax basis in the Building Property would be
equal to the fair market value of the Reservoir on the date of the Property
Exchange Closing, plus the $200,000 paid by Aquarion to MELP as a part of the
Property Exchange.

THE FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED FOR GENERAL
INFORMATION ONLY. EACH NCC SHAREHOLDER IS URGED TO CONSULT HIS, HER OR ITS OWN
TAX ADVISOR AS TO SPECIFIC FEDERAL AND OTHER TAX CONSEQUENCES OF THE TRANSACTION
TO SUCH SHAREHOLDER.

                       RIGHTS OF DISSENTING SHAREHOLDERS

   The applicable CSCA provisions (the "Dissenters' Rights Statute") provide
that NCC Shareholders ("Dissenting Shareholders") who object to the Acquisition
described in this Prospectus/Proxy Statement have the right to be paid the value
of all their shares upon compliance with the provisions of the Dissenters'
Rights Statute. Specifically, Section 33-373(d) of the CSCA provides that if a
corporation sells all or substantially all of its assets primarily in
consideration of securities of another corporation, and such transaction is part
of a general plan of liquidation and dissolution, substantially equivalent to a
merger any shareholder objecting to such sale shall have the right to be paid
the value (calculated as provided in the statute) of the shares of stock of such
corporation owned by him.

                                       29
<PAGE>
 
   The following summary of the Dissenters' Rights Statute is necessarily
incomplete; and reference to the full text of the Dissenters' Rights Statutes
that is annexed as Exhibit H to this Prospectus/Proxy Statement.

   Dissenting Shareholders electing to exercise their statutory rights must
satisfy all of the following requirements: (1) deliver to NCC written notice of
objection to the transaction prior to the Meeting, or at the Meeting prior to
the vote on the Acquisition; (2) not vote any of their shares in favor of the
Acquisition and Liquidation Proposal; (3) deliver to NCC, within ten (10) days
after the vote on the Acquisition, a written demand to purchase the shares; and
(4) deliver to NCC, within twenty (20) days after the demand, their share
certificates for notation thereon that such demand has been made. Failure to
deliver the share certificates will, at the option of the NCC and in the absence
of a court decision to the contrary, terminate a shareholder's rights under the
Dissenters' Rights Statute.

   The notice and demand required by the Dissenters' Rights Statute should be
delivered to The New Canaan Company, 59 Grove Street, New Canaan, Connecticut
06840, Attention: Secretary. The demand must state the number and classes of
shares owned by the Dissenting Shareholder. Any shareholder making such demand
shall thereafter be entitled only to payment for the shares, and shall not be
entitled to vote, receive dividends or exercise any other shareholder rights.
Failure to make the demand required by the statute will bind a shareholder to
the terms of the Acquisition. The demand may not be withdrawn without the
consent of NCC.

   At any time after receipt of the statutory notice, but not later than ten
(10) days after receipt of a demand to purchase shares or ten (10) days after
the Acquisition is consummated, whichever is later, NCC is obliged to make a
written offer to purchase the shares. The Dissenters' Rights Statute requires
that the price specified in the offer be the fair value of the shares (i)
determined as of the day prior to the date on which NCC mailed this
Prospectus/Proxy Statement and (ii) exclusive of any element of value arising
from the expectation of consummating the Transaction.

   If the Dissenting Shareholder accepts NCC's offered price, NCC must make
payment upon surrender of the share certificates. If NCC defaults or refuses to
pay the price specified in its offer, the Dissenting Shareholder may file a
petition for such amount in the Superior Court for the Judicial District of
Stamford-Norwalk.

   If NCC and any shareholder satisfying the Dissenters' Rights Statute's
requirements fail to agree in writing on a price for the shares within sixty
(60) days after NCC was required by the statute to make an offer to purchase,
either party may file suit in the Connecticut Superior Court for the Judicial
District of Stamford-Norwalk, requesting the court to determine the fair value
of the shares. All shareholders who have made proper demand and have not
accepted NCC's offered price must be made parties to this lawsuit. The court may
appoint one or more appraisers to determine the fair value of the shares. The
costs and expenses of such a proceeding will be assessed against NCC unless the
court finds that the refusal of all or some of the Dissenting Shareholders to
agree to the price offered by NCC was arbitrary, vexatious or not in good faith.
In such a case, the court may assess costs and expenses, including the
appraisers' reasonable compensation and reasonable expenses, against such
shareholders.

   A shareholder's rights under the Dissenters' Rights Statute will terminate
and his, her or its status as a shareholder will be restored upon the occurrence
of any one of the following events: (1) the shareholder's demand is withdrawn
with the consent of NCC; (2) NCC abandons or rescinds the Transaction; (3) the
approving vote at the Meeting is revoked; (4) a demand or petition for
determination of fair value is not made within the statutory time period; or (5)
a court of competent jurisdiction determines that the shareholder is not
entitled to the relief requested.

   Shareholders intending to exercise their rights under the Dissenters' Rights
Statute are advised to consult with counsel, as failure to comply strictly with
the statutory provisions may deprive such shareholders of their rights.

                 INTEREST OF CERTAIN PERSONS IN THE TRANSACTION

   Joseph J. McLinden has served and is serving as the President, a Director and
a member of the Executive Committee of the Board of Directors of each of NCC,
NCWC and RWSC; and he has been the principal representative of NCC in
negotiating the terms of the Acquisition since March, 1990. He owns 20 shares of
NCC Class B Common Stock. On March 6, 1993, the NCC Board adopted a resolution
awarding Mr. McLinden the amount of $105,000 which represents 3% of the purchase
price before reductions and excluding the assumption of debt.

   Prior to his retirement on May 31, 1991, Nicholas Negria served as the Senior
Vice President, a Director and a member of the Board of Directors of NCWC; and
he participated in the negotiations of the terms of the Transaction. On
September 15, 

                                       30
<PAGE>
 
1990, the NCC Board adopted a resolution awarding Mr. Negria the amount of
$50,000 which represents to 2 1/2% of the Purchase Price. On May 16, 1991, Mr.
Negria and NCWC agreed on a retirement benefits package for Mr. Negria whereby:
(1) Mr. Negria is being paid $75,000 over a ten-year period that commenced July
1, 1991, in monthly installments of $625, provided that if the Acquisition is
consummated any unpaid balance will be paid within 30 days after the Closing
Date; (2) Mr. Negria was paid one month's salary in lieu of his accrued vacation
and unused sick time pay on the date of his retirement; (3) NCWC is providing
NCWC's group medical and hospital insurance coverage to Mr. Negria and his wife
for his lifetime; (4) Mr. Negria received the cash value of his vested interest
in the RWSC Pension Plan (in which NCWC employees also participate); and (5) Mr.
Negria was afforded the right to remain in possession of a residence on NCWC
property until June 30, 1991. The 1991 agreement superseded and replaced the
1990 resolution awarding Mr. Negria an amount equal to 2 1/2% of the Purchase
Price.

   As of September 30, 1994, NCC owed an aggregate amount of $68,000 to Mr. A. 
Glidden, a director of NCC and the owner of 23.1% of the Class A Common Stock 
and 51.5% of the Class B Common Stock, and members of his family.  At September 
30, 1994, NCWC and RWSC owed an aggregate of $100,000 to A. Glidden.  The 
indebtedness described in this paragraph will be paid by BHC and will reduce 
the amount of $3,500,000 in calculating the Purchase Price.

DESCRIPTION OF THE BUSINESS OF NCC'S SUBSIDIARIES

NEW CANAAN WATER COMPANY

   NCWC was incorporated by Special Act of the Connecticut legislature in 1889.
It collects, treats, purchases and distributes water to residential and
commercial customers in New Canaan and to the Town of New Canaan, and to a small
portion of the adjacent town of Stamford, Connecticut. NCWC provides water
directly to approximately 3,300 customers. NCWC management does not anticipate
significant growth in residential consumption in the foreseeable future, and
expects stability or small growth in commercial water use. NCWC's water supply
is available from both company-owned and non-owned subsurface sources and from
the Regional Pipeline. During 1993, approximately 93% of the water supplied by
NCWC to its customers was obtained from the Regional Pipeline and non-owned
subsurface sources.

   NCWC distributes its water by taking water from the Regional Pipeline at the
Little Brook Pump Station and pumping it into the system through 54 miles of
water mains. A booster pumping station increases the pressure for the higher
elevations at the northern end of the serviced area. A two million gallon tank
helps maintain pressure for the system and provides water storage for peak
demand times as well as for fire protection.

   As a regulated utility with an assigned service area, NCWC can not attract
new business or raise or lower its rates without regulatory approval. With the
town of New Canaan showing no population growth over the past several years, the
company does not anticipate increased revenues from expansion of its customer
base. Most of the growth is occurring with respect to commercial construction.
NCWC does not anticipate any difficulty in meeting any growing demand from this
segment of its customer base.

   In 1986, NCWC switched from the New Canaan Reservoir to the Regional Pipeline
for its main source of water supply. This was a result of the company's
determination that it would be less costly to participate in the construction of
the pipeline and pay for actual water usage than to install and maintain a
filtration plant at the reservoir to meet newly enacted water quality
legislation. The company purchases the water from the pipeline under an
agreement with BHC. See "Proposed Acquisition--Certain Transactions Between
Aquarion and NCC."

   On May 3, 1994, NCWC filed with the DPUC an application seeking approval of
the sale of approximately forty (40) acres of unimproved land (the "Property")
currently classified as "Class III" by DPUC and the DPHAS. No part of this Class
III land has frontage on or access to a public highway, and this land abuts
Class I and Class II land of NCWC that surrounds and comprises its property
known as the New Canaan Reservoir. The terms and conditions of the sale and
purchase were set forth in the proposed contract of sale dated of March 24,
1994, as amended by an Addendum dated as of June 6, 1994. This application of
NCWC is pending before the DPUC. The purchasers will not purchase the Property
unless it has access to a public highway, the nearest of which is Michigan Road
in New Canaan. In order to provide the Property with access to Michigan Road,
either NCWC or the purchasers must acquire from owners of an adjacent parcel of
land, a strip of land at least 50 feet in width (the "Parcel") which would
provide the NCWC Class III land with access to Michigan Road by linking the
Parcel to other Class II land of NCWC which abuts its Class III land.

   This access involving the Parcel and Class II land requires approval of the
DPHAS. NCWC has filed applications with DPHAS for approval to use NCWC's Class
II land to provide a 50 foot wide access strip linking NCWC's Class III land and
the Parcel. The DPHAS has not responded as yet to the NCWC application for
approval to create the 50 foot wide access strip on the Class II land. On
November 30, 1994, the purchasers and the owners of the land executed a letter
of intent with respect to the sale of the Parcel directly to the purchasers.

   NCWC intends to use the proceeds from the sale of the Property to pay the
principal of a loan from the Village Bank and Trust Company to NCWC in the
amount of $1,250,000. That loan is secured by the Property, and must be paid in
order to obtain a release of the mortgage at the closing of the land sale. If
the closing of the sale of the Property does not occur prior to the Closing
Date, BHC will assume this debt and will acquire the Property by virtue of the
Acquisition. See

"Management's Discussion and Analysis of Financial Condition and Results of
Operations of New Canaan Company--Financial Condition and Liquidity."

RIDGEFIELD WATER SUPPLY COMPANY

   RWSC was incorporated by Special Act of the Connecticut Legislature in 1893.
It collects, treats and distributes water to residential and commercial
customers, and to the Town of Ridgefield, in Ridgefield, Connecticut. RWSC
provides water directly to approximately 2,200 customers. Fire protection is
also provided through 307 public and private fire hydrants in
the service area. Its service area is primarily residential in nature. RWSC
management does not anticipate significant growth in residential consumption,
and expects small growth in commercial water consumption in the foreseeable
future.

   The Company's sources of supply are the Round Pond Reservoir, the Oscaleta
Well Field, the North Street Well Field and the Beechwood Well Field, all of
which are located in Ridgefield. The total output of these sources is
approximately 1.1 million gallons per day which, together with the 488,000
gallon capacity of the Standpipe located at Peaceable Ridge Road in Ridgefield,
is more than adequate to meet the average daily demand of 825,000 gallons per
day. Water is pumped from Round Pond Reservoir and the Oscaleta Well Field
through two separate transmission lines into the distribution system and into
the Standpipe. When the demand exceeds the volume being pumped, water is gravity
fed to the system from the Standpipe. Water from the other two well fields is
pumped directly into distribution mains.

   If a prolonged dry spell occurs during the summer months, daily demand can
equal 1.1 million gallons per day. If that happens, RWSC places a ban on
watering lawns in the serviced area during the period of the shortage. (Because
of this potential shortfall, RWSC is now operating under a moratorium for all
new service connections other than single unit residences. An additional source
of supply consisting of two wells located on the Titicus River near Hessian
Drive is capable of producing approximately 300,000 gallons per day. It is
expected to be placed in service in 1995 and will allow the company to lift the
moratorium on new service connections.

   RWSC's offices are located in Ridgefield, and the maintenance and supply
facility adjoins the pump house at the Round Pond Reservoir. The company has
five full time employees and two part time employees. The Company also pays a
portion of the salaries of three of its officers, who are employees of NCWC.
Four of the five full time employees are involved in the pumping, maintenance
and distribution operations of RWSC and the fifth employee performs office and
clerical work. The part time employees perform clerical and bookkeeping tasks.

SEASONALITY OF DEMAND

   The businesses of both NCWC and RWSC are subject to seasonal fluctuations and
weather variations. The demand for water during the warmer months is greater
than during the cooler months, due primarily to additional water requirements of
customer cooling systems and various private and public outdoor uses, such as
lawn sprinkling. From year to year and season to season demand will vary with
rainfall and temperature levels. During dry summers when demand for water is
high, RWSC can experience water shortages as described above.

OPERATING AUTHORITY

   Both NCWC and RWSC are incorporated under and operate as public water
utilities by virtue of authority granted by Special Acts adopted by the
Connecticut legislature (Acts). These Acts afford franchises, unlimited in
duration, to provide public water supply to private and public customers in
designated municipalities and adjacent areas. The Acts also authorize NCWC and
RWSC to lay their mains and conduits in public streets, highways and public
grounds, and to exercise the power of eminent domain in connection with lands,
springs, streams or ponds and any rights or interests therein which are
expedient to or necessary for furnishing public water supply. In the event of
the exercise of any condemnation powers, appropriate compensation must be paid
to those injuriously affected by the taking.

REGULATION

   Both NCWC and RWSC are subject to regulation by the DPUC, which has
jurisdiction with respect to rates, service, accounting procedures, issuance of
securities, dispositions of utility property and other related economic matters.
Customer rates are subject to approval by the DPUC. Each of NCWC and RWSC has
its own rate structure and is separately regulated 

                                       34
<PAGE>
 
for ratemaking and other purposes by the DPUC. The following table sets forth
information regarding rate increase requests by NCWC and RWSC, and increases
granted by the DPUC, in their respective last three rate proceedings.

- ---------

(1)  The original application actually requested an increase of 38.9%. The
     request was lowered to 26.0% in the aggregate by amendments dated July 25,
     1988, October 6, 1988 and October 27, 1988.
(2)  The original application actually requested an increase of 31.1%. The
     request was subsequently revised to 26.2% and then to 25.33% on May 1,
     1989.
(3)  Indicates that the number was calculated and not given in the decision.
(4)  The decision asserts that "[t]he approved revenues result in an overall
     increase in revenues of 8.58%. The increase in rates charged to water
     service customers is approximately 8.61%.

   When RWSC applied to the DPUC for rate relief in 1988, the application
included the estimated costs of installing and operating the two new Beechwood
Wells. When it became clear that the wells would not be completed before the
rate case was decided, the company removed these costs from its application with
the belief that it would include the costs in a limited reopening of the rate
case when the project was completed. Due to the protracted process of attempting
to obtain a diversion permit for the wells from the DEP, the project was not
completed until the summer of 1993, when it was too late to reopen the 1988 rate
case to add these costs. This caused the RWSC to incur substantial expenses
which were financed from deferring account payables and from short term
borrowings.

   In January, 1994, RWSC applied for a 42.9% rate increase. On July 19, 1994
the DPUC granted a 33% increase in annual revenue.

   On June 25, 1993, RWSC entered into a Consent Order with the Connecticut
Department of Health and Addiction Services regarding the installation of a
filtration system at the company's Round Pond Reservoir. The Public Health Code
required such installation to be completed by June 29, 1993, but the Company was
unable to meet this deadline. Under the terms of the Consent Order, voluntarily
entered into by RWSC, the compliance date was extended to June 29, 1997. Three
pilot studies on a new filtration method have been performed at the Round Pond
reservoir and design work on a system employing this method should be completed
before the January 1, 1995 deadline stipulated in the Consent Order for this
stage of the project.

   In 1994, the Connecticut Department of Environmental Protection cited RWSC
for non-compliance with certain regulations and orders of that Department. The
alleged violations included failure to register sources of supply that were in
use prior to adoption of the department's Diversion Permit regulations, failure
to renew permits for two other sources of supply, and violation of certain
provisions of the Diversion Permit issued in 1992 for the company's Beechwood
Wells. The Department proposed to issue and RWSC agreed to accept a Consent
Order calling for the correction of certain violations and the payment of
$20,000, of which $15,000 represented fees that were not paid and $5,000
represented a penalty. RWSC has received a draft of the proposed Consent Order,
which is under review by the company and its counsel. RWSC 's principal defense
in the matter was that the inordinate delay in obtaining the Beechwood Wells
Diversion Permit and the 

                                       35
<PAGE>
 
consequent delay in receiving rate relief deprived the Company of the funds that
were required to perform the action that the DEP required.

   NCWC and RWSC are also subject to regulation by the DPHAS with respect to
water quality matters, use of water from surface and subsurface sources, the
location, construction and operation of water supply facilities and the sale of
certain properties. Plans for new water supply systems or enlargement of
existing water supply systems also must be submitted to the DPHAS for approval.
DPHAS has primary enforcement responsibility for regulations promulgated by the
federal Environmental Protection Agency under the Safe Drinking Water Act of
1974, and by the DPHAS itself, establishing minimum water quality standards and
water treatment requirements for all public drinking water.

   The DEP is authorized to regulate the operations of NCWC and RWSC with
respect to water pollution abatement, diversion of water from surface and
subsurface sources, and the location, construction, alteration and operation of
dams and other water obstructions and facilities that affect, or discharge
effluents into state or interstate waters. Aquifer protection legislation in
Connecticut requires each water utility to conduct extensive groundwater data
collection and groundwater mapping of critical wellfield areas. The DEP is also
proposing land use regulations within these critical areas. The Aquifer
protection legislation also mandates that each municipality designate an Aquifer
protection agency to regulate land use in these areas.

   Developments with respect to the identification and measurement of various
elements in water supplies and concern about the effect of such elements on
public health, together with possible contamination of water sources, may in the
future require NCWC and/or RWSC to modify all or portions of their respective
water supplies, to develop replacement supplies or to implement new treatment
techniques. Any such developments would significantly increase the affected
utility's operating costs and capital requirements.

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
              AND RESULTS OF OPERATIONS OF THE NEW CANAAN COMPANY

CONSOLIDATED RESULTS OF OPERATIONS

YEAR ENDED DECEMBER 31, 1993 ("1993") COMPARED WITH YEAR ENDED DECEMBER 31, 1992
("1992").

   Operating Revenues. Revenues of $2,875,772 in 1993 were $207,776 higher than
1992 revenues of $2,667,996, principally due to the increased demand for water
during the extremely hot summer of 1993. This increase represented a 7.8%
increase in revenues for 1993 compared with 1992.

   Operating expenses and other expenses. Operating expenses for 1993 were
$1,704,724 compared with $1,608,075 in 1992. This increase of $96,649, or 6.0%,
was due primarily to higher costs of meeting the increased demand for water in
1993. Maintenance expense increased from $138,814 in 1992 to $152,539 in 1993,
an increase of $13,725 or 9.9% for the same reason. Depreciation expense for
1993 was $247,390, an increase of $16,345 over 1992. This increase was due to
the disposal by NCWC of certain vehicles that were not fully depreciated at the
time of sale.

   Interest expense and taxes. Interest expense in 1993 was $264,036, compared
with 1992 interest expense of $267,576. Tax expense other than income tax
expense was $266,580 for 1993, compared with $252,014 for 1992. This increase of
5.8% was due primarily to increased payroll taxes and property taxes. Federal
and state income tax expense for 1993 totalled $135,545, an increase of $43,145
or 46.7% over combined federal and state income tax expense of $92,400 for 1992.
The increase in 1993 was due to increased income based on the increased revenues
and the timing of the recognition of income in NCC.

   Operating income. NCC's operating income for 1993 was $349,554, compared with
$328,716 for 1992. This increase of $20,838, or 6.3%, resulted from NCC's higher
revenues in 1993, offset by higher taxes and operating expenses. NCC's net
income for 1993 was $142,967 compared with net income for 1992 of $104,654. This
increase was due to slightly higher operating income in 1993 and an increase of
$20,718 in the allowance for funds used during construction ("AFUDC") from
$34,620 in 1992 to $55,338 in 1993. These AFUDCs were primarily a result of the
work on the Beechwood Well project.

<PAGE>
 
YEAR ENDED DECEMBER 31, 1992 ("1992") COMPARED WITH YEAR ENDED DECEMBER 31, 1991
("1991").

   Operating Revenues. Revenues of $2,667,996 in 1992 were $33,577 less than
1991 revenues of $2,701,573, a 1.2% decrease in revenues for 1992. Revenues were
fairly constant due to flat demand and rates.

   Operating expenses and other expenses. Operating expenses for 1992 were
$1,608,075 compared with $1,796,971 in 1991, representing a decrease of
$188,896, or 10.5%. This difference relates to a one time write off of deferred
land sale costs amounting to approximately $200,000 which were considered no
longer appropriate to carry on the balance sheet.
Maintenance expense increased from $86,435 in 1991 to $138,814 in 1992, an
increase of $52,379 or 60.6% This increase resulted from an increase in the
number of water main breaks in 1992. Depreciation expense for 1992 was $231,045,
an increase of $6,396 over 1992.

   Interest expense and taxes. Interest expense in 1992 was $267,576, compared
with interest expense in 1991 of $312,830. This decrease of $45,254, or 14.5%,
was due to lower interest rates. Tax expense other than federal and state income
tax expense was $252,014 for 1992, compared with $245,809 in 1991. Federal and
state income tax expense for 1992 totalled $92,400, an increase of $70,029 or
313% over combined federal and state income tax expense of $22,371 for 1991.

   Operating income and net income. NCC's operating income for 1992 was
$328,716, compared with $305,654 for 1991. This increase of $23,062, or 7.5%,
resulted from the company's lower operating expenses in 1992, offset by lower
revenues. NCC's net income for 1992 was $104,654 compared with net income for
1991 of $17,719. This increase was due to slightly higher operating income in
1992 and an allowance for funds used during construction of $34,620 in 1992.
This item, together with the $45,254 reduction in interest expense, contributed
directly to the improved net income in 1992.

NINE MONTHS ENDED SEPTEMBER 30, 1994 COMPARED WITH NINE MONTHS ENDED SEPTEMBER
30, 1993

   Operating Revenues. Revenues for the nine months ended September 30, 1994
were $2,209,510 compared with $2,256,665 for the nine months ended September 30,
1993, a decrease of $47,155 or 2.1%. This decrease is insignificant. The RWSC
rate increase did not take effect until July 19, 1994, and therefore such
increase did not significantly impact revenues for the period.

   Operating Expenses and Operating Income. Operating expenses increased from
$1,213,954 for the nine months ended September 30, 1993, to $1,337,586 for the
corresponding period in 1994, representing an increase of 10.2%. This increase
together with the higher tax expense resulted in the decrease in operating
income from $373,079 for the nine months ended September 30, 1993 to $296,941
for the corresponding period in 1994.

   Depreciation and Interest Expense. Depreciation expense for the nine month
period in 1993 was $179,747, compared with $185,856 for the corresponding period
in 1994, an increase of 3.3%. Interest expense increased from $188,933 for the
period ended September 30, 1993, compared with $234,213 for the corresponding
period in 1994.

   Taxes. Tax expense other than income tax expense decreased by $29,334, from
$202,237 for the period ended September 30, 1993 to $172,903 for the
corresponding period in 1994. Federal income tax expense decreased, from
$142,926 for the nine months ended September 30, 1993, to $47,252 for the
corresponding period in 1994. State income tax expense decreased by $13,115,
from $38,882 for the period ended September 30, 1993 to $25,767 for the
corresponding period in 1994.

FINANCIAL CONDITION AND LIQUIDITY.

   Neither of NCC's subsidiaries is able to obtain financing from banks or other
lending institutions due to the fact that the DPUC, the economic regulatory body
that has jurisdiction over these entities, places certain restrictions on the
debt to equity ratios of regulated utilities. Borrowing additional funds would
place the subsidiaries' ratios above those permitted by DPUC, and therefore that
body would not permit such additional borrowing. In addition, NCC has been
unable to attract new equity capital due to the fact that the Company's dividend
policy is below average for that of a regulated utility and the balance sheet of
RWSC is weak. For these reasons, the operating subsidiaries of NCC must use cash
flow from operations for all of its capital improvement requirements. Net cash
from operating activities decreased from $228,727 for the nine months ended
September 30, 1993, to $210,186 for the corresponding period in 1994. In
addition, net cash provided from financing activities was $552,410 at September
30, 1993 due to borrowings of $670,222, for that period, from The Village Bank &
Trust Company. In contrast, net cash used from financing activities for the nine
months ended September 30, 1994 

                                       37
<PAGE>
 
was $128,886. Cash on hand at September 30, 1994 was $55,675, a decrease of
$144,827 from the $200,502 on hand at the end of the nine months ended September
30, 1993.

   As of September 30, 1994, neither NCWC nor RWSC had any commitments for
capital expenditures. The companies do, however, have five year capital
improvement plans. These various improvements must be financed from the
operating proceeds of the companies, to the extent they are available for such
purposes.

   On September 30, 1994, NCWC had outstanding long-term debt of $2,850,166, of
which $1,303,169 was due and payable within one year. This consisted principally
of a loan to NCWC from the Village Bank & Trust Company ("VBT") which is due on
February 28, 1995. If the acquisition does not occur, NCWC will have to
renegotiate this loan or attempt to refinance such loan with new borrowings.
This loan is due upon the sale by NCC of 25% or more of the capital stock of
NCWC. NCWC intends to repay this loan with the proceeds of the sale of certain
land located in New Canaan, which is more fully described in "Business of NCC."
If such sale does not occur and the Acquisition is consummated, BHC will assume
the obligation to VBT. BHC has indicated that it will refinance such loan upon
the consummation of the Acquisition. If such sale does not occur, NCWC will have
to attempt to renegotiate such loan and will continue to market such land in
order to retire such debt as soon as practicable.

   RWSC had outstanding long term debt of $322,901 on September 30, 1994,
consisting of a note payable to VBT in the principal amount of $200,000 and a
secured loan from the CDA in the principal amount of $200,000. The loan from VBT
matures in five years.

   In addition, RWSC has an outstanding loan of $525,000 from VBT, which is due
and payable on February 28, 1995. This loan will be refinanced by BHC if the
Acquisition is consummated. If the Acquisition is not consummated, RWSC has
obtained a commitment from the Connecticut Development Authority, which
commitment expires on April 7, 1995, to refinance this loan from VBT.

   Minimum principal payments due on long term debt for both of NCC's
subsidiaries for 1995 total $45,170. Of the $74,945 of principal payments due in
1994, $47,135 was paid as of September 30, 1994.

                     DESCRIPTION OF AQUARION CAPITAL STOCK

   The Aquarion Common Stock that will be delivered to NCC at the Acquisition
Closing and distribution in liquidation of NCC to NCC'S Common Stock
Shareholders, will be newly issued from the authorized but unissued shares of
Aquarion's Common Stock. These shares, when delivered pursuant to the
Acquisition Agreement, will be duly authorized, validly issued, fully paid and
non-assessable. Aquarion is authorized to issue up to 16,000,000 shares of
Common Stock, no par value (stated value $1), of which 6,570,130 were
outstanding on September 30, 1994, and 2,500,000 shares, in one or more series,
of Preferred Stock, no par value, in an aggregate stated value not in excess of
$25,000,000, of which no shares have been issued. Other significant provisions
of Aquarion's capital stock, including provisions relating to corporate
governance, are described under the caption "Comparison of Shareholder Rights."
The description herein and under the caption "Comparison of Shareholder Rights"
include brief summaries of certain provisions relating to the Aquarion Common
Stock and Aquarion's Preferred Stock contained in its Certificate of
Incorporation and do not purport to be complete.

COMMON STOCK

   Holders of Aquarion Common Stock are entitled to cast one vote per share on
each matter submitted to a vote of stockholders of Aquarion. Holders of Aquarion
Common Stock do not have any cumulative voting rights, which means that the
holders of more than 50% of the outstanding Common Stock voting in the election
of directors can elect all of the directors if they so choose and, in such
event, the holders of the remaining shares will not be able to elect any
director.

   Each of the outstanding shares of Aquarion Common Stock will share equally in
respect to all dividends paid on such Common Stock. The Certificate of
Incorporation empowers Aquarion's Board of Directors to issue Preferred Stock
with such preferences and other rights as the Board of Directors may provide in
the resolutions providing for the issuance of such Preferred Stock. Such
preferences and other rights may restrict or otherwise limit the rights of
holders of Aquarion Common Stock to receive dividends. For a description of the
Company debt and subsidiary debt and preferred stock provisions which could
limit payment of Common Stock dividends directly or indirectly, see "Aquarion
Stock Price Ranges and Dividends."

   In the event of any liquidation, dissolution or winding up of the affairs of
Aquarion, whether voluntary or involuntary, all assets available for
distribution to its stockholders, after the payment to the holders of Preferred
Stock, if any, at the time outstanding of the full amounts to which they shall
be entitled, shall be divided and distributed pro rata among the holders of
Aquarion Common Stock.

   The outstanding Aquarion Common Stock is fully paid and nonassessable, and
all of the shares of Common Stock offered hereby, when issued, will be fully
paid and nonassessable. The shares are listed on the NYSE.

   All holders of record of Aquarion Common Stock are eligible to participate in
Aquarion's Dividend Reinvestment and Common Stock Purchase Plan. The holders of
Common Stock have no preemptive rights.

   The Transfer Agent and Registrar of Aquarion Common Stock is Mellon Financial
Services, 85 Challenger Road, Ridgefield, New Jersey 07660.

PREFERRED STOCK

   Aquarion's Board of Directors is empowered to issue up to 2,500,000 shares of
Preferred Stock in one or more series with such voting powers, full or limited,
or no voting powers, and such designations, preferences and relative,
participating, optional or other special rights and qualifications, limitations
and restrictions thereof as the Board of Directors may specify in the
resolutions providing for the issuance of such Preferred Stock. The Board of
Directors, without shareholder approval, can issue Preferred Stock with voting
and conversion rights which could limit the voting rights of holders of Aquarion
Common Stock.

   The issuance of Preferred Stock may have the effect of delaying, deferring or
preventing a change in control of Aquarion. While Aquarion's Board of Directors
has no present plans to issue any Preferred Stock, it has designated a series of
Preferred Stock, which is issuable in certain circumstances, and issued rights
to purchase such Preferred Stock to holders of Common Stock. The preferred stock
purchase rights are exercisable only in the event of certain threatened changes
in control described more fully below under the caption "Comparison of
Shareholder Rights--Preferred Stock Purchase Rights."

                       COMPARISON OF SHAREHOLDER RIGHTS

   Upon the consummation of the Acquisition and the Liquidation, stockholders of
NCC, a Connecticut corporation, will become shareholders of Aquarion, a Delaware
corporation. Differences between the laws of Connecticut and those of Delaware,
and between NCC's Certificate of Incorporation, as amended ("NCC's Certificate
of Incorporation"), and by-laws and Aquarion's Certificate of Incorporation, as
amended ("Aquarion's Certificate of Incorporation") and by-laws will result in
several changes in the rights of stockholders of NCC when the Acquisition and
the Liquidation are effected. A summary of the more significant changes is set
forth below.

POWERS OF DIRECTORS IN ISSUANCE OF SHARES

   Both the CSCA and the DGCL provide that, subject to the limitations contained
in the certificate of incorporation of a corporation, the Board of Directors of
a corporation shall have the authority to issue additional shares of the
corporation's capital stock up to the amount authorized in its Certificate of
Incorporation, and dispose of or receive subscriptions for the corporation's
shares.

   NCC's Certificate of Incorporation provides that the Board of Directors may
issue and sell all or any part of the shares of stock of any class of the
corporation, from time to time, without further action by stockholders.

   Aquarion's Certificate of Incorporation empowers the Board of Directors to
issue and dispose of both Preferred Stock and Common Stock with such voting
powers, full or limited, or no voting powers, and such designations, preferences
and relative, participating, optional or other special rights, and
qualifications, limitations and restrictions thereof as the Board may decide.
The Aquarion Board of Directors, without shareholder approval, can issue
Preferred Stock with voting and conversion rights which could limit the voting
rights of holders of Aquarion Common Stock. The issuance of Preferred Stock may
have the effect of delaying, deferring or preventing a change in control of
Aquarion. Aquarion's Board of Directors has designated two series of Preferred
Stock; $5.50 Convertible Preferred Stock ("Convertible Preferred Stock") and
Series A Junior Participating Preferred Stock ("Series A Preferred Stock"). No
shares of either series are outstanding. However, the Series A Preferred Stock
is issuable in certain circumstances, and Aquarion has issued rights to purchase
such Preferred Stock to holders of Common Stock. The preferred stock purchase
rights are exercisable only in the event of certain threatened changes in
control described more fully below.

VOTING RIGHTS

   Both the CSCA and the DGCL provide that every stockholder shall be entitled
to one vote for each share of capital stock held by such stockholder unless
otherwise specified in the Certificate of Incorporation. Both the DGCC and the
CSCA also provide that the holders of outstanding shares of any class of stock
shall, regardless of any limitations or restrictions in the Certificate of
Incorporation, be entitled to vote as a class upon any proposed amendment to the
Certificate of Incorporation submitted to shareholder vote which would have
certain specified effects on their rights.

   NCC's Certificate of Incorporation provides that holders of Class A Common
Stock are not entitled to vote or receive notice of any stockholders meetings
unless the corporation is in default on dividends payable to such holders.

      (1) If the amount in arrears reaches $2.00 or more, the holders of the
   Class A Common Stock entitled to one vote per share, notice of all
   shareholder meetings, and the right as a class to elect all directors in
   excess of a majority of members of the Board of Directors until such time as
   the corporation shall have paid all dividends in arrears.

      (2) If the dividends in arrears amount to $4.00 or more, the holders of
   the Class A Common Stock are entitled to one vote per share, notice of all
   shareholder meetings, and the right as a class to elect a majority of members
   of the Board of Directors until such time as the corporation shall have
   reduced the amount of dividends in arrears to less than $4.00.

   Subject to the rights of the Class A Common Stock set forth in NCC's
Certificate of Incorporation and the CSCA, the holders of Class B Common Stock
shall have exclusive voting power.

                                       40
<PAGE>
 
   Holders of Aquarion Common Stock are entitled to cast one vote per share on
each matter submitted to a vote of stockholders of Aquarion. If issued, each
share of Convertible Preferred Stock would have [four] votes, representing the
number of shares of Common Stock into which a share of Convertible Preferred
Stock is convertible. If issued, each share of Series A Preferred Stock would
have 150 votes per share.

PREEMPTIVE RIGHTS

   NCC's and Aquarion's Certificate of Incorporation each eliminates preemptive
rights to subscribe to any future issues of shares of Common Stock.

DISSENTERS' RIGHTS OF APPRAISAL

   The CSCA grants dissenters' rights to shareholders (i.e. the right to cash
payment of the fair value of one's shares determined by judicial appraisal) in
the case of a merger or consolidation, a sale of all or substantially all of the
corporation's assets, and certain other corporate transactions. The CSCA also
grants appraisal rights to holders of preferred shares, in the case of certain
amendments to a corporation's certificate of incorporation.

   The DGCL grants appraisal rights to any stockholder opposing a merger or
consolidation. Both the CSCA and the DGCL restrict the appraisal rights of
shareholders of the merging domestic corporation which is to be the surviving
corporation. The DGCL eliminates appraisal rights for such shareholders if the
merger did not require for its approval the vote of the holders of the surviving
corporation. Similarly, the CSCA grants such shareholders appraisal rights only
if the merger effects an amendment to the certificate of incorporation of the
surviving corporation which would entitle the shareholder to such a vote, or if
the merger provides for the distribution to shareholders of any form of property
in exchange for the shares of the surviving corporation.

   Both the CSCA and the DGCL define the concept of "fair value" in payment for
shares upon exercise of dissenters' rights as being exclusive of any element of
value arising from the expectation or accomplishment of such corporate
transaction.

DIVIDENDS AND DISTRIBUTIONS

   Each of the outstanding shares of Aquarion Common Stock will share equally in
respect to all dividends paid on such Common Stock but only after all dividends
have been paid on the Convertible Preferred Stock and the Series A Preferred
Stock.

   Holders of Aquarion's Series A Preferred Stock, if issued, would be entitled
to receive dividend, voting and liquidation rights which are at least 150 times
the equivalent rights of one share of Aquarion Common Stock. The rights would
become exercisable only if a person or group acquires 20% or more of the
outstanding Aquarion Common Stock, or if a person or group announces or
commences a tender or exchange offer for 30% or more of Aquarion's Common Stock.

   In the event of any liquidation, dissolution or winding up of the affairs of
Aquarion, whether voluntary or involuntary, all assets available for
distribution to its stockholders, after the payment to the holders of Preferred
Stock, shall be divided and distributed pro rata among the holders of Aquarion
Common Stock.

   NCC's Certificate of Incorporation provides that the holders of Class A
Common Stock are entitled to receive dividends from the net profits of NCC in
priority to any dividend on the Class B Common Stock. If, for any reason,
dividends are not declared on the outstanding Class A Common Stock, no dividend
can be declared upon any Class B Common Stock. Furthermore, after paying the
dividends on the outstanding Class A Common Stock, the Class A Common Stock as a
class, shall be entitled to participate equally with the Class B Common Stock in
the receipt of any further dividends during any one year to the extent that the
holders of Class A Common Stock receive not more than an additional fifty cents
per share of Class A Common Stock.

   In the event of any dissolution or liquidation of the Corporation, whether
voluntary or involuntary, after payment to the holders of Class A Common Stock
and before any distribution is made with respect to the Class B Common Stock,
the remaining assets shall be divided among the holders of the Class B Common
Stock, ratably in accordance with their ownership of Class B Common Stock.

                                       41
<PAGE>
 
FILLING DIRECTOR VACANCIES

   Aquarion's Certificate of Incorporation and By-Laws provide that any newly
created or vacated directorship may be filled only by a majority vote of the
directors then in office, although less than a quorum. However, if an applicable
provision of the DGCL expressly confers the right to fill the vacancy on the
stockholders, then such directorship may be filled only by the affirmative vote
of at least 80 percent of the combined voting stock.

   NCC's By-Laws provide that, upon the occurrence of a vacancy of any director
or directors, a majority of the remaining directors, although less than quorum,
shall choose a successor or successors.

REMOVAL OF DIRECTORS

   Aquarion's By-Laws and Certificate of Incorporation provide that, subject to
the rights of preferred stockholders, any director, or the entire Board of
Directors, may be removed from office at any time, but only for cause and only
by the affirmative vote of the holders of at least 80 percent of the combined
voting power of all of the then-outstanding shares of the voting stock, voting
together as a class. Such director, however, shall have an opportunity, at the
expense of the corporation, to present his defense to the stockholders.

   The CSCA leaves the prerequisite conditions for removal of directors up to
the corporation to develop in its By-Laws. The CSCA provides that a director
shall cease to be in office upon his removal from office in accordance with the
By-Laws adopted by shareholders or upon any other lawful removal from office.

   NCC's By-Laws provides that a vacancy on the board can occur by a director's
removal from office, but does not prescribe how removal is to be effected.

AMENDMENTS TO CERTIFICATE OF INCORPORATION

   Under the CSCA, amendments to the Certificate of Incorporation for a
corporation with at least one hundred recordholders requires the affirmative
vote of the majority of the voting power of the shares entitled to vote thereon,
and if any class of shares is entitled to vote thereon as a class, by the
affirmative vote of the holders of the shares of each class of shares entitled
to vote thereon as a class.

   The CSCA requires the affirmative vote of at least two-thirds of the voting
power of the shares of each class of stock outstanding and entitled to vote
thereon for corporations with less than one hundred recordholders.

   Under the DGCL and the CSCA, the holders of the outstanding shares of any
class, regardless of any limitations or restrictions in the Certificate of
Incorporation, shall be entitled to vote as a class upon any proposed amendment
to the Certificate of Incorporation submitted to shareholder vote which would
affect their rights in certain specified ways.

   NCC's Amended Certificate of Incorporation requires the affirmative vote of
two-thirds of outstanding shares of Class A Common Stock to adopt an amendment
(i) increasing the authorized number of shares of Class A Common Stock or
authorizing any other shares ranking equally with the Class A Common Stock, (ii)
adversely affecting the Class A Common Stock or (iii) amending the purposes of
the corporation.

   Under the DGCL, a majority of the stockholders entitled to vote on amendments
to the Certificate of Incorporation is necessary to effectuate adoption of such
amendment.

   Aquarion's Certificate of Incorporation requires a supermajority vote of 80%
of the combined voting power of all of the then-outstanding shares of the voting
stock to alter, amend or repeal the provisions in the Certificate of
Incorporation described under "Filling Director Vacancies," "Removal of
Directors," "Business Combinations with Interested Stockholders,"
"Classification of Board of Directors" and "Shareholder Meetings."

AMENDMENTS TO BYLAWS

   NCC's By-Laws provide that the bylaws may be amended or repealed by the
affirmative vote of a majority of the holders of the Class B Common Stock issued
and outstanding and entitled to vote; or may be altered or amended by the
affirmative vote of a majority of the Board of Directors at any regular or
special meeting of the Board.

                                       42
<PAGE>
 
   Both Aquarion's certificate of incorporation and by-laws provide that
Aquarion's by-laws may be amended by the Board of Directors with the exception
that amendment of certain provisions requires the affirmative vote of 80% of the
outstanding shares entitled to vote. Those by-law provisions are those relating
to membership and classification of the Board, filling of Board vacancies,
removal of directors, shareholder action, calling of special meeting of
shareholders, quorum at Board meetings, business combinations with certain
stockholders or their affiliates and amendment of the foregoing voting
requirements.

BUSINESS COMBINATIONS WITH INTERESTED STOCKHOLDERS

   Aquarion's Certificate of Incorporation requires the approval by the holders
of 80% of the voting power of Aquarion's securities as a condition for certain
Business Combinations of Aquarion with any holder of more than 10% of such
voting power unless certain minimum price and procedural requirements or certain
other conditions are met. The term Business Combination is defined to include
certain mergers, dispositions of assets, issuances of securities and similar
transactions.

   NCC's Certificate of Incorporation does not have a comparable provision.

BUSINESS COMBINATION STATUTES

   The DGCL Business Combination Statute generally prohibits a corporation from
engaging in any business combination with any interested stockholder for a
period of three years following the date that such stockholder became an
interested stockholder, unless:

   (1) prior to such date the board of directors of the corporation approved
       either the business combination or the transaction which resulted in the
       stockholder becoming an interested stockholder, or

   (2) upon consummation of the transaction which resulted in the stockholder
       becoming an interested stockholder, the interested stockholder owned at
       least 85% of the voting stock of the corporation, or

   (3) on or subsequent to such date the business combination is approved by the
       board of directors and authorized at an annual or special meeting of
       stockholders, and not by written consent, by the affirmative vote of at
       least two-thirds of the outstanding voting stock which is not owned by
       the interested stockholder.

   In general, "interested stockholder" is defined as the holder of 15% of the
outstanding voting stock of the corporation.

   The CSCA Business Combination Statute does not apply to NCC because it is a
private corporation and its certificate of incorporation does not opt-in to the
CSCA Business Combination Statute.

CLASSIFICATION OF THE BOARD OF DIRECTORS

   Aquarion's Certificate of Incorporation provides that directors (other than
directors who may be elected by preferred stockholders) are to be classified
into three classes, which are to hold office in staggered three-year terms.

   NCC's Board of Directors is not classified into classes.

SHAREHOLDER MEETINGS

   Aquarion's Certificate of Incorporation provides that shareholder action may
only be taken at an annual or special meeting of stockholders and not by written
consent. Special meetings of stockholders may be called only by the Board of
Directors and otherwise by shareholders as expressly permitted by applicable
statute.

   Under the CSCA, any action which may be taken at a meeting of shareholders
may be taken without a meeting by unanimous written consent or, if so provided
by the Certificate of Incorporation, by the written consent of a majority of the
voting power of shares. The CSCA also provides that special meetings of the
shareholders may be called only by the board of directors, or by such person or
persons as may be authorized by the certificate of incorporation or the bylaws.
However, the president is required to call a special shareholders' meeting upon
the written request of the holders of not less than 1/10 

                                       43
<PAGE>
 
of the voting power of all shares entitled to vote at the meeting. If the
president fails to call such meeting within 15 days after the receipt of such
shareholders' request, the shareholders may call the meeting.

PREFERRED STOCK PURCHASE RIGHTS

   Aquarion has reserved 80,000 shares of Preferred Stock for issuance under its
Preferred Stock Purchase Rights Plan. Each share of Aquarion Common Stock,
including the shares offered hereby, is entitled to one right to buy, under
certain circumstances, 1/150th of a share of Series A Preferred Stock at $83.33
per 1/150th of a share.

   Each share of Series A Preferred Stock, if issued, would have dividend,
voting and liquidation rights which are at least 150 times the equivalent rights
of one share of Common Stock. The rights would become exercisable only if a
person or group acquires 20% or more of Aquarion's outstanding Common Stock, or
if a person or group announces or commences a tender or exchange offer for 30%
or more of Aquarion's Common Stock. Were Aquarion to be acquired in a merger or
other business combination transaction ,each right would entitle its holder to
receive, upon payment of the exercise price, that number of shares of the
acquiring company having a market value equal to twice the exercise price. If,
under certain circumstances, a 20% or greater stockholder acquires Aquarion
through a transaction in which Aquarion and its Common Stock survive or such
stockholder engages in certain self-dealing transactions with Aquarion, each
right holder (other than a 20% or greater stockholder) would be entitled to
receive, upon payment of the exercise price, the greater of (a) the number of
shares of Series A Preferred Stock for which such right was exercisable
immediately prior to such self-dealing transaction or (b) that number of shares
of Series A Preferred Stock having a market value equal to twice the exercise
price.

   Aquarion may redeem the rights at $.033 per right any time until the 10th day
after a 20% position has been acquired or a 30% tender offer has been commenced.
The redemption period is subject to extension by Aquarion's Board of Directors.
Until such time as these rights become exercisable, they will have no dilutive
effect on Aquarion's earnings and are tied to Aquarion's Common Stock and may
not be separately assigned. The rights will expire on December 3, 1996, unless
earlier redeemed.

INDEMNIFICATION OF DIRECTORS AND OFFICERS

   The DGCL provides that a corporation may indemnify officers and directors for
proceedings arising by reason of the fact that such person served as an officer
or director if such person acted in good faith and in a manner he reasonably
believed "not opposed to" the best interests of the corporation. However, in the
case of a proceeding brought by or in the right of the corporation, if such
person is adjudged to be liable to the corporation, the DGCL requires that a
court determine whether, despite the adjudication of liability, such person is
fairly and reasonably entitled to indemnity for such expenses.

   The CSCA provides that a corporation shall indemnify any person in any
proceeding, by reason of the fact that such person is or was a director or
officer of the corporation if:

   (1) such person is successful on the merits in defense of such proceeding; or

   (2) the corporation concludes that such person acted in good faith and in a
       manner he reasonably believed to be in the best interests of the
       corporation; or

   (3) the court, upon application, shall have determined that such person is
       fairly and reasonably entitled to indemnification.

   In the case of an action by or in the right of a corporation, the CSCA
provides that the corporation shall indemnify an officer or director if the
individual is adjudged not to have breached his duty to the corporation or if a
court shall determine that the individual is fairly and reasonably entitled to
be indemnified. An officer or director may not be indemnified for amounts paid
in settlement of such an action without court approval.

   Whereas the CSCA indemnification provision is made the exclusive remedy and
prohibits any indemnity to an extent greater or less than that authorized by the
statute (except that the corporation may procure insurance to provide greater
indemnity and may share the premium cost with a person indemnified), the DGCL
indemnification provision is non-exclusive of other rights to which prospective
indemnitees may be entitled under any by-law, agreement, vote of stockholders or
otherwise.

   Aquarion's by-laws reflect the statutory provisions described above.

                                       44
<PAGE>
 
   NCC's Certificate of Incorporation provides that directors and officers shall
be indemnified for expenses incurred in defending any action brought against
them by reason of their being a director or officer, unless such director or
officer is judged to be liable for negligence or misconduct in the performance
of duty. The CSCA provision is also applicable by reason of its being an
exclusive remedy.

   Aquarion's By-Laws also provide that the Corporation, through action by its
Board of Directors, may purchase indemnity insurance for directors, officers,
employees or agents of the Corporation.

                                    EXPERTS

                             ----------------------

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                   ------------------------------------------

                                   UNAUDITED
                                   ---------

NOTE 1 - GENERAL
- ----------------

The New Canaan Company (the "Company" or "NCC") is engaged predominantly in the
collection, purification and distribution of water for domestic, commercial,
industrial and fire protection services through its utility subsidiaries, The
New Canaan Water Company ("NCWC") and The Ridgefield Water Supply Company
("RWSC"). The Company's utility subsidiaries are subject to regulation by the
Connecticut Department of Public Utility Control ("DPUC") with respect to their
rates for service and the maintenance of their accounting records.

The financial statements include the accounts of NCC, NCWC and RWSC.  Minority
interest in subsidiary represents the minority shareholders' proportionate share
of the equity of The Ridgefield Water Supply Company. All intercompany items
have been eliminated in consolidation.

NOTE 2 - BASIS OF PRESENTATION
- ------------------------------

The accompanying consolidated financial statements of the Company have been
prepared in accordance with generally accepted accounting principles for interim
financial information and, as applied in the case of rate-regulated public
utilities, comply with the Uniform System of Accounts and rate making practices
prescribed by the DPUC. Accordingly, they do not include all of the information
and footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of management, all adjustments (consisting
of normal recurring accruals) considered necessary for a fair presentation have
been included. The results of operations are not necessarily indicative of the
results of operations for the calendar year. Water consumption is less in the
first and fourth quarters of the year than during the warmer months. For further
information, refer to the consolidated financial statements and  accompanying
footnotes included in the Company's financial statements for the year ended
December 31, 1993.

NOTE 3 - DEBT
- -------------

On March 31, 1994, NCWC refinanced its mortgage loan. The new mortgage loan
bears interest at the lenders pricing rate plus 2%. Interest payments are due
quarterly on the unpaid principal balance. The loan will be amortized over
twenty years with the balance in five years. The loan is secured by a mortgage
deed and assignment of rents on certain real property and a guaranty by NCC.

This loan was entered into pending DPUC approval. During 1994 the DPUC denied
approval of this mortgage loan. The Company has subsequently revised its
agreement with the bank requiring the Company to pay the loan in full during the
first quarter of 1995. This revised mortgage loan agreement is pending approval
of the DPUC.

                       REPORT OF INDEPENDENT ACCOUNTANTS



To the Board of Directors and Shareholders of
The New Canaan Company

   In our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of income and retained earnings and of cash flows
present fairly, in all material respects, the financial position of The New
Canaan Company and its subsidiaries at December 31, 1993, and the results of
their operations and their cash flows for each of the two years in the period
ended December 31, 1993 in conformity with generally accepted accounting
principles. 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 of these statements in
accordance with generally accepted auditing standards which require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for the opinion expressed
above.

   As discussed in Note 1 and Note 7 to the financial statements, the Company
changed its method of accounting for income taxes.

                             THE NEW CANAAN COMPANY
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

  The New Canaan Company (the "Company" or "NCC") is engaged predominantly in
the collection, purification and distribution of water for domestic, commercial,
industrial and fire protection services through its utility subsidiaries, The
New Canaan Water Company ("NCWC") and The Ridgefield Water Supply Company
("RWSC"). The company's utility subsidiaries are subject to regulation by the
Connecticut Department of Public Utility Control ("DPUC") with respect to their
rates for service and the maintenance of their accounting records. The company's
accounting policies conform to generally accepted accounting principles and, as
applied in the case of regulated public utilities, comply with the accounting
requirements and ratemaking practices of the DPUC. A description of the
company's principal accounting policies follows.

PRINCIPLES OF CONSOLIDATION:

  The financial statements include the accounts of The New Canaan Company
("NCC"), The New Canaan Water Company ("NCWC") and The Ridgefield Water Supply
Company ("RWSC"). Minority interest in subsidiary represents the minority
shareholders' proportionate share of the equity of The Ridgefield Water Supply
Company. All intercompany items have been eliminated in consolidation.

UTILITY PLANT:

  Utility plant is stated at cost. The costs of additions to and replacements of
retired units of utility property are capitalized. Cost includes direct
material, labor, services and charges for such indirect costs as engineering,
supervision, payroll taxes, pension benefits, etc. The company also capitalizes
an allowance for funds used during construction equivalent to the cost of funds
devoted to plant under construction. Renewals and betterments of units of
property are charged to utility plant accounts, and expenditures for maintenance
and repairs are charged against income as incurred.

  At the time that depreciable utility property is retired or otherwise disposed
of, the book cost together with cost of removal, less salvage, is charged to the
reserve for depreciation. This procedure is in accordance with the requirements
of the Uniform System of Accounts prescribed by the DPUC. At the time
depreciable non-utility property is retired or otherwise disposed of, the
accumulated depreciation together with any amounts realized on disposal are
offset against the cost of the applicable assets, and the resulting profit or
loss is recognized in the consolidated statement of income and retained
earnings.

DEPRECIATION:

  For financial reporting purposes, all companies provide depreciation
principally by use of the composite straight-line method based on estimated
service lives. For federal income tax purposes, all Companies use accelerated
depreciation methods for eligible property, plant and equipment. From January 1,
1985 to December 31, 1986, the Accelerated Cost Recovery System (ACRS) had been
used for all utility property, plant and equipment. As a result of the Tax
Reform Act of 1986, all plant additions subsequent to December 31, 1986 are
depreciated in accordance with the Modified Accelerated Cost Recovery System.

ALLOWANCE FOR FUNDS USED DURING CONSTRUCTION:

  An allowance for funds used during construction (AFUDC) is made by applying
the last allowed rate of return on rate base granted by the DPUC to construction
projects exceeding $10,000 and requiring more than one month to complete. AFUDC,
as defined in the DPUC's Uniform System of Accounts, includes the net cost, for
the period of construction, of borrowed funds used for construction purposes and
a reasonable rate on other funds when so used. AFUDC, thus, represents a noncash
credit to income. Utility plant under construction is not recognized as part of
the utility subsidiaries' rate base for ratemaking purposes until facilities are
placed into service and, accordingly, the utility subsidiaries charge AFUDC to
the construction cost of utility plant until it is completed. Capitalized AFUDC
is recovered through rates over the service lives of the facilities.

                                      F-10

REVENUE RECOGNITION:

  The Company follows the practice of recognizing revenue when the bills are
rendered to customers, and accruing revenue for the estimated amount of water
sold but not billed at the end of each period.

MATERIALS AND SUPPLIES:

  Materials and supplies are valued at the lower of cost or market, with cost
being determined using the weighted average cost of goods purchased during the
year.

INCOME TAXES:

  Except for accelerated depreciation since 1981 (federal only) and the tax
effect of post-1986 contributions in aid of construction, for which deferred
income taxes have been provided, the Company's policy, prior to 1993, was to
reflect as income tax expense the amount of tax currently payable. This method,
known as the flow-through method of accounting, was consistent with the
ratemaking policies of the DPUC, and was based on the expectation that tax
expense payments in future years will be allowed for ratemaking purposes.

  Effective January 1, 1993, the company adopted Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes" (SFAS 109),
prospectively. The adoption of SFAS 109 changes the Company's method of
accounting for income taxes from the deferred method (in accordance with
Accounting Principles Board No. 11) to an asset and liability approach. In
accordance with SFAS 109, the deferred tax provision was determined under the
liability method. Deferred tax assets and liabilities were recognized based on
differences between the book and tax bases of assets and liabilities using
presently enacted tax rates. The provision for income taxes is the sum of the
amount of income tax paid or payable as determined by applying the provisions of
enacted tax laws to the taxable income for that year and the net change during
the year in the Company's deferred tax assets and liabilities.

  In addition, SFAS 109 required the Company to record an additional deferred
liability for temporary differences not previously recognized. This additional
deferred tax liability totalled $331,582 at December 31, 1993, primarily
relating to depreciation, investment tax credits and contributions in aid of
construction. Management believes that these deferred taxes will be recovered
through the ratemaking process. Accordingly, the Company has recorded an
offsetting regulatory asset and liability.

ADVANCES FOR CONSTRUCTION/CONTRIBUTIONS IN AID OF CONSTRUCTION:

  Most construction contracts with real estate developers provide that the
developer advance to the utility subsidiaries an amount equal to the estimated
cost of new main installations. The utility subsidiaries refund a portion of
such advances, without interest, based upon several formulas, over periods not
exceeding ten years. After expiration of the contract the remaining balance of
the advance is transferred to "Contributions in aid of construction" and are no
longer refundable.

STATEMENT OF CASH FLOWS:

  For purposes of reporting cash flows, the Company defines cash equivalents as
cash and short-term investments that are readily convertible to cash with
original maturities of three months or less. Interest paid in cash was $282,798
and $265,389 in 1993 and 1992, respectively. Income taxes paid in cash were
$33,000 and $34,500 in 1993 and 1992, respectively. Additions to utility plant
are shown net of donations.

NOTE 2 - NOTES PAYABLE TO BANK:

    In December 1992, The Ridgefield Water Supply Company executed an agreement
which provides for financing totaling $525,000. The note bears interest at the
prime rate plus 2%. This note is due and payable in full on September 1, 1994.
At December 31, 1993, borrowings of $525,000 were outstanding. This note is
guaranteed by The New Canaan Company. The Company has received a commitment from
a lending institution to finance this note over a twenty year period pending
approval of the rate application filed with the DPUC. See Note 9.

NOTE 3 - NOTES PAYABLE, OTHER:

  Notes payable, other, include six-month to one-year term notes payable on
demand to employees and others, bearing interest of 8.0% to 10.5%. These notes
are unsecured.

  Notes payable by NCWC and RWSC to shareholders totaling $140,000 are due on
demand and bear interest rates of 9.0% to 10.0%.

  Notes payable by NCC to shareholders totaling $68,000 are non-interest
bearing.

  The Connecticut Development Authority (CDA) loan is secured by all real and
personal property except for subordination of interests in certain real property
to the mortgage loan described below.

  On March 31, 1994, NCWC refinanced its mortgage loan. The loan bears interest
at the lenders pricing rate plus 2%. Interest payments are due quarterly on the
unpaid principal balance. The loan will be amortized over twenty years with the
balance in five years. The loan is secured by a mortgage deed and assignment of
rents on certain real property and a guaranty by NCC. The agreement requires
that if the NCC transfers more than 25% of the capital stock of NCWC, the entire
principal sum becomes due and payable on demand.

  The master line of credit bears an annual interest rate of 9% and is payable
in equal installments, including interest, over an 18 month term ending January
1994.

  In 1986, RWSC entered into a thirty-year first mortgage loan agreement with
the CDA. The loan is secured by all of RWSC's real and personal property.

  Minimum principal payments due on long-term debt for the next five years are
as follows:

          Section 7.3 Judgment.  Any claim based upon a final judgment after
                      --------                                              
right to appeal has expired, decree or award of a court of competent
jurisdiction requiring the payment of money by the party claiming the right to
indemnification, or any of its officers, directors, employees, agents,
investment advisors or controlling persons ("Claimant"), shall be conclusive as
to the amount of such claim, provided a certified copy of such judgment, decree
or award accompanies the notice relating to such claim and provided further that
Claimant shall have complied with Section 7.4 of this Agreement.

          Section 7.4 Procedure.  In the event that any action, investigation or
                      ---------                                                 
legal proceeding shall be instituted, or any claim or demand shall be asserted,
by any third party in respect of which indemnity may be sought pursuant to the
provisions of this Article VII, Claimant shall, with reasonable promptness after
obtaining knowledge of such action, investigation, proceeding, claim or demand,
give written notice thereof to the indemnifying party or parties ("Indemnitor"),
who shall then have the right, at its option and at its own expense, to be
represented by counsel of its choice in connection with such matter, which
counsel shall be reasonably satisfactory to Claimant (counsel representing each
party in this transaction shall be deemed satisfactory), and to defend against,
negotiate, settle or otherwise deal with any such proceeding, claim or

                                                                              65

demand; provided, that without the prior written consent of Claimant, Indemnitor
        --------                                                                
shall not consent to the entry of any judgment in or agree to any settlement of
any such matters.  Should Indemnitor desire to settle any proceeding and
Claimant desire to continue the proceeding, Indemnitor shall have the option of
paying Claimant the amount of the proposed settlement and Claimant, at its own
expense, will take over defense of the proceeding and will be responsible for
any judgment or settlement amount.  Claimant may retain counsel to represent it
and participate in connection with any such proceeding or claim or demand, at
its own expense, unless (i) the Indemnitor and the Claimant shall have mutually
agreed to the retention of such counsel or (ii) the named parties to any such
proceeding (including any impleaded parties) include both the Indemnitor and the
Claimant and representation of both parties by the same counsel would be
inappropriate due to actual or potential differing interests between them.
Failure to notify or delay in notifying Indemnitor will not relieve it from any
liability which it may have to such Claimant under this Article VII except to
the extent it or they have been prejudiced in any material respect to such
failure or from any liability which it or they may have to an indemnified party
or parties otherwise than under this Agreement.  Failure by Indemnitor to notify
Claimant of Indemnitor's election to defend any action, proceeding, claim or
demand with respect to which indemnity is sought within twenty (20) business
days after notice thereof shall have been received by Indemnitor, shall be
deemed a waiver by Indemnitor of its

                                                                              66

right to defend against any such matter.  If Indemnitor assumes defense of any
such proceeding, claim or demand, it shall take or cause to be taken all steps
necessary in connection with such defense, and Claimant shall in all events be
entitled to indemnity with respect to such matter, as provided in this Article
VII.  In the event that Indemnitor does not elect to defend any Proceeding,
claim or demand with respect to which indemnity is sought, Claimant may defend
against, settle or otherwise deal with any such action, proceeding, claim or
demand in such manner as it may in its good faith discretion deem appropriate
and Indemnitor shall be liable for indemnification with respect to such matter,
including without limitation the reasonable costs of such defense, as provided
in this Article VII.  In the event of any proceeding, claim or demand by a third
party with respect to which a claim for indemnification is made hereunder, the
parties hereto agree that they will cooperate fully with each other in
connection with the defense or settlement of such matter.

          Section 7.5 Limitations on Indemnity.
                      ------------------------ 

          (a)  Seller's, the Seller's former stockholders' and Buyer's
obligations for indemnification shall be limited to claims for indemnification
for which notification in writing or for which claim is made within forty-eight
(48) months of the Closing Date.

          (b)  Overall Limit; Basket.  The indemnification obligations of either
               ---------------------

Section 1.2 above.  The indemnification obligations of each formal stockholder
of Seller hereunder is limited as follows: (i) each former stockholder's
liability will be limited in the aggregate to the amount of distribution such
stockholder actually received from Seller, and (ii) each former stockholder's
liability for any individual indemnification claim will be limited to the
greater of $100,000 or such former stockholder's pro rata portion of such claim,
determined by dividing the amount of distribution to such stockholder by the
total amount distributed to all stockholders.  No indemnification amount shall
be payable hereunder by a party unless and until the aggregate indemnification
liability of such party hereunder shall exceed $32,500, and after exceeding such
account, such indemnification liability shall not include such $32,500.

          (c)  Officers and Directors.  No provision of this agreement is
               ----------------------                                    
intended to alter the liability of officers and directors of Buyer or Seller in
circumstances in which such officers and directors would have personal
liability.

          (d)  The Seller shall use its best efforts to obtain from each of its
stockholders prior to closing written consent for the designation of one agent
to receive service of process on behalf of each such stockholder for any action
or proceeding brought by the Buyer to enforce the indemnification obligation
imposed by this Article VII on any former stockholder of Seller.  The Seller
need not seek such consent from any stockholder who receives liquidating
distributions totalling less than $4,000.

Buyer shall pay all expenses in connection with the administration of such
agent's duties, if any.

          XII.  DELAY, TERMINATION AND ABANDONMENT.
                ---------------------------------- 

          (a)  Termination Events:  This Agreement may be  terminated  and
               -------------------                                        
abandoned at any time prior to the Closing:

          (1)  by mutual written consent of all the parties;

          (2)  by any party in the event the Closing does not occur before
     December 31, 1992 through no fault of the terminating party, provided,
                                                                  --------

     Closing for 365 days, provided, further, that any extension of the Closing
                           --------  -------                                   
     Date pursuant hereto shall not be construed to effect the Closing Date, or
     any extension thereof, set forth in the Acquisition Agreement;

          (3)  if the transaction contemplated by the Acquisition Agreement does
     not occur or the Acquisition Agreement is terminated.

          (b)  Delay.  If all of the contingencies provided in Articles IV
               -----                                                      
through VI have been satisfied, waived or otherwise removed, and on the Closing
Date, either MELP or NCWC shall be unable to convey the title to its property in
accordance with the terms of this Agreement, free and clear of encumbrances,
liens or exceptions to title other than those set forth herein, then, and in
that event, Closing shall be delayed until the affected party shall have a
further period of thirty (30) days within which to clear title, and the Closing
Date shall be extended for such period, if necessary.  If, at the end of said
thirty (30) day period, the Transferor is still unable to convey title to the
affected property free and clear of all encumbrances, liens or exceptions to
title, except as aforesaid, then the Transferee shall either (1) elect to accept
such title as can be conveyed, or (2) as the Transferee's sole and exclusive
remedy, shall reject the deed proposing to convey such title on that ground.
Upon such rejection, this Agreement shall terminate and became null and void.
Nothing shall constitute an encumbrance, lien or exception to title for the
purposes of this Agreement if the Standard of Title of the Connecticut Bar
                                  -----------------                       
Association recommends that no corrective or curative action is necessary in
circumstances substantially similar to those presented by such encumbrance, lien
or exception to title.

               ------------------------------                                 
or the Reservoir or any part thereof is damaged or destroyed by fire or other
casualty, or in the event condemnation or eminent domain proceedings (or private
purchase in lieu

                                                                              35

thereof) shall be commenced by any public or quasi-public authority having
jurisdiction against all or any part of the property, then the Transferor shall
promptly notify the other parties.  The Transferee may, at its option, by giving
written notice the Transferor within thirty (30) days after receipt of notice of
such casualty or condemnation proceedings, terminate this Agreement.  In the
event the Transferee does not elect to terminate this Agreement, then all
insurance proceeds and/or any awards in condemnation, as the case may be, will
be assigned to the Transferee at the time of settlement hereunder, or, if paid
to the Transferor prior thereto, shall be paid over to the Transferee.  The
Transferor shall not adjust or settle any insurance claims or condemnation
awards whatsoever without the prior written approval of the Transferee; further,
the Transferee and its counsel shall have the right (prior to settlement) to
participate in all negotiations relating to any such insurance claims or
condemnation awards.

          (d) Effect Of Termination.  If any party has the right to terminate
              ---------------------                                          
this Agreement pursuant to this Article XII and such party shall terminate this
Agreement pursuant to this Article XII, all obligations for the parties
hereunder (other than those set forth in Article XIII(a) hereof shall terminate
and no party shall have any obligation or liability to any of the other parties
with respect to any breach of any of its obligations hereunder regardless of
whether such breach is outstanding or curable at the date of such termination;
provided,

abandoned, changed or modified in any manner, except by an instrument in writing
signed on behalf of each of the parties hereto.  The failure of any party hereto
to enforce at any time any of the provisions of this Agreement shall in no way
be construed to be a waiver of such provisions, nor in any way to affect the
validity of this Agreement or any part thereof or the right of any party
thereafter to enforce each and every such provision.  No waiver of any breach of
this Agreement shall be held as a waiver of any other or subsequent breach.

          1. Plan of Liquidation.
             ------------------- 

          After (i) the adoption of this Plan, (ii) the consummation of the
transactions contemplated in that certain Acquisition Agreement, dated as of
September __, 1992 (the "Acquisition Agreement"), as amended and (iii) the
amendment of the Corporation's certificate of incorporation to provide that
liquidation preference of the Corporation's Class A common stock, can be paid in
cash or in other property, THE NEW CANAAN COMPANY, a Connecticut corporation
(the "Corporation"), will distribute to its shareholders its properties and
assets of every description, which at that time will consist entirely of common
stock of Aquarion Company, a Connecticut corporation ("Aquarion"), together with
dividends paid thereon, received by the Corporation as the Purchase Price (as
defined in the Acquisition Agreement) for the assets of the Corporation pursuant
to the terms of the Acquisition Agreement (the "Aquarion Shares").

          2. Escrow.
             ------ 

          Initially, the Corporation shall retain 10% of the Aquarion Shares
(the "Escrow Shares") from the distribution that would otherwise be made to
holders of shares of Class B Common Stock of the Corporation.  The Escrow Shares
shall then be transferred by the Corporation to the escrow agent pursuant to
such escrow.

Upon termination of the escrow, the Escrow Shares shall be distributed to the
Class B Shareholders of the Corporation in accordance with the escrow agreement
and such holders' relative holdings of Class B Common Stock on the Closing Date.
The number of shares of Aquarion common stock arrived at by subtracting the

          (a) After the escrow described in the previous paragraph has been

for the amount of their claims, (ii) possession of the Escrow Shares will remain
with the escrow agent pursuant to the terms of the escrow agreement, and (iii)
no partial shares of Aquarion stock will be distributed, but, rather, cash will
be distributed in an amount equal to the value of any such partial shares on the
date of such distribution.

          (b) The distribution of the Initial Distribution Shares shall be as
follows:

          (i)   Holders of Class A Common Stock shall be entitled to receive,

unpaid dividends to the date of distribution.

          (ii)  The remainder of the Aquarion Shares available as part of the
Initial Distribution Shares will be distributed to the Holders of the Class B
Common Stock based on their relative holdings of such stock on the Closing Date.

          (iii) Dividends paid or payable with respect to the Initial
Distribution Shares will be distributed pro-rata to the holders of the Class A
Common Stock and the Class B Common Stock together with the distribution of the
Initial Distribution Shares.

          (iv) Dividends paid or payable in cash with respect to the Escrow
Shares will be distributed [as received] [upon termination of the escrow] to the
holders of the Class B Common Stock in accordance with their respective holdings
of such shares.

          The foregoing distributions in complete liquidation shall be in
exchange solely for, and in complete redemption and cancellation of, and in
payment for, all of the outstanding shares of Class A Common Stock and Class B
Common Stock of the Corporation, and the shareholders shall, if the Board of
Directors so determines, surrender their certificates for such shares for
recording thereon receipt of distributions prior to the final distribution, and
shall surrender such certificates for cancellation upon receipt of the final
distribution herein authorized.

          The officers and the Board of Directors of the Corporation shall

the Corporation for any action under this Plan taken in good faith, and any

                   TEST OF SECTIONS 33-373 AND 33-374 OF THE
                      CONNECTICUT GENERAL CORPORATION LAW

   33-373 RIGHTS OF OBJECTING SHAREHOLDERS.--(a) Any objecting holder of
preferred shares shall have the right to be paid the value of all shares of such
class owned by him in accordance with the provisions of section 33-374 if an
amendment to the certificate of incorporation is effected which would: (1)
Cancel or otherwise affect the right to accrued dividends or other arrearages in
respect of such class of shares; (2) reduce the dividend preference thereof; (3)
make noncumulative, in whole or in part, dividends thereof, which had
theretofore been cumulative; (4) reduce the redemption price thereof or make
such shares subject to redemption when not otherwise redeemable; (5) reduce any
preferential amount payable thereon upon voluntary or involuntary liquidation.

   (b) If an offer is made by the corporation to holders of its shares of any
class having accrued dividends or other arrearages to exchange such shares for
other securities of the corporation which would be entitled to preference in the
receipt of any periodical payment or dividend over such shares, and if the offer
is accepted by, and such exchange is effected with, any holder of such shares,
then any other holder of such shares who objects to the terms of the offer shall
have the right to be paid the value of all shares of such class owned by him in
accordance with the provisions of section 33-374.

   (c) Any shareholder of a merging or consolidating domestic corporation who
objects to the merger or consolidation shall have the right to be paid the value
of all shares of such corporation owned by him in accordance with the provisions
of section 33-374, except that a shareholder of a merging domestic corporation
which is to be the surviving corporation shall have such right only: (1) if and
to the extent that the plan of merger will effect an amendment to the
certificate of incorporation of the surviving corporation which would entitle
the shareholder to such right pursuant to the provisions of subsection (a) of
this section, or (2) if the plan of merger provides for the distribution to
shareholders of the surviving corporation of cash, securities or other property
in lieu of or in exchange for or upon conversion of outstanding shares of the
surviving corporation.

   (d) If a corporation sells all or substantially all its assets primarily in
consideration for securities of another corporation, domestic or foreign, and
such transaction is part of a general plan of liquidation and distribution
substantially equivalent to a merger, any shareholder of such corporation
objecting to such sale shall have the right to be paid the value of all shares
of such corporation owned by him in accordance with the provisions of section
33-374.

   (e) If a distribution to shareholders, by dividend, liquidating distribution
or otherwise, is effected by transfer of assets in kind to shareholders
collectively as co-owners, any objecting shareholder who would otherwise receive
such distribution shall have the right to be paid the value of all shares of
such corporation owned by him in accordance with the provisions of section 33-
374.
   (f) Where the right to be paid the value of shares is made available to a
shareholder by this section, such remedy shall be his exclusive remedy as holder
of such shares against the corporate transactions described in this section,
whether or not he proceeds as provided in section 33-374.

   33-374 PROCEDURE FOR OBJECTING SHAREHOLDER.--(a) As used in this section, the
term (1) "corporation" includes, if the context so indicates, the successor,
surviving or new corporation which acquires the property of a predecessor
corporation upon a sale of assets for securities, merger or consolidation; (2)
"the date on which the exchange was effective" means the date on which the
corporation first actually consummated an exchange of shares or, if it reserved
the right to postpone the operation or effectiveness of all acceptances of its
offer of exchange, the date on which it declared the acceptance operative or
effective; (3) "sale of assets for securities" means a sale of assets entitling
objecting shareholders to be paid the value of shares pursuant to subsection (d)
of section 33-373; (4) "shares" of a shareholder means those shares owned by him
as to which he is entitled to be paid the value pursuant to the provisions of
section 33-373.

   (b) Any shareholder designated in section 33-373 as having the right to be
paid the value of shares as provided in this section may elect to exercise such
right by giving notice to the corporation, in writing, objecting to the proposed
corporate transaction giving rise to such right. (1) In the case of a
shareholder so designated in subsections (a), (c) and (d) of section 33-373 such
notice shall be delivered to the corporation prior to the meeting of
shareholders called for the purpose of voting on such transactions, or at such
meeting prior to voting on such transaction, or prior to the time action taken
by consents as

                                       1
<PAGE>
 
provided in section 33-330 shall become effective. If such transaction is
approved, any such shareholder so notifying the corporation, provided none of
his shares shall have been voted in favor thereof, may require the corporation
to purchase his shares at fair value by delivering to the corporation a demand
to that effect in writing, within ten days after the date on which the vote was
taken or action taken by consents as provided in section 33-330 became
effective. (2) In the case of a shareholder so designated in subsection (b) of
section 33-373, such notice shall be delivered to the corporation within fifteen
days after the date of mailing the offer. If an exchange is effected with any
shareholder, any such shareholder so notifying the corporation, provided none of
his shares shall have been so exchanged, may require the corporation to purchase
his shares at fair value by delivering to the corporation a demand to that
effect in writing, within ten days after the date on which the exchange was
effective if the corporation shall give notice of such date to such shareholder
or within sixty days after delivering the written notice to the corporation,
whichever is the earlier. (3) A shareholder so designated in subsection (e) of
section 33-373 may require the corporation to purchase his shares at fair value
by delivering such notice to the corporation within fifteen days after the date
of mailing the distribution or any notice thereof from the corporation,
whichever is earlier, accompanied by a demand to that effect in writing,
provided such shareholder shall not have accepted such distribution. (4) In the
case of a shareholder so designated in subsection (c) of section 33-373, where a
merger has been effected as provided in section 33-370, such notice shall be
delivered to the corporation within fifteen days after the date of mailing the
plan of merger and be accompanied by a demand in writing that the corporation
purchase his shares at fair value.

   (c) Any demand to purchase shares under subsection (b) of this section shall
state the number and classes of shares of the shareholder making the demand.
Except as provided in subsection (i) of this section, any shareholder making
such demand shall thereafter be entitled only to payment as in this section
provided and shall not be entitled to vote, to receive dividends or to exercise
any other rights of a shareholder in respect of such shares. No such demand may
be withdrawn unless the corporation consents thereto. Any shareholder failing to
make demand as provided in subsection (b) shall be bound by the corporate
transaction involved in accordance with its terms.

   (d) At any time after the receipt of a notice by a shareholder objecting to
the proposed corporate transaction giving rise to rights under this section, but
not later than ten days after receipt of a demand to purchase shares or ten days
after the corporate transaction is effective, whichever is later, the
corporation shall make a written offer, to each shareholder who makes demand as
provided in this section, to pay for his shares at a specified price deemed by
such corporation to be the fair value thereof as of the day prior to the date on
which notice of the proposed corporate transaction was mailed, exclusive of any
element of value arising from the expectation or accomplishment of such
corporate transaction.

   (e) Within twenty days after demanding the purchase of his shares, each
shareholder so demanding shall submit the certificate or certificates
representing his shares to the corporation for notation thereon that such demand
has been made. His failure to do so shall, at the option of the corporation,
terminate his rights under this section unless a court of competent
jurisdiction, for good and sufficient cause shown, otherwise directs. If shares
represented by a certificate on which notation has been so made are transferred,
each new certificate issued therefor shall bear similar notation, together with
the name of the shareholder of such shares who made such demand, and a
transferee of such shares shall acquire by such transfer no rights in the
corporation other than those which such shareholder had after making such
demand.

   (f) If the corporation and any shareholder making a demand to purchase shares
under subsection (b) of this section agree in writing as to the value of the
shares, the corporation shall pay such shareholder such value upon and
concurrently with the surrender to the corporation of the certificate or
certificates representing such shares duly endorsed for transfer. If the
corporation defaults in or refuses to make such payment, such shareholder may
file a petition in the superior court for the judicial district where the
principal office of the corporation is located, praying that judgment be entered
for such amount, and such shareholder shall be entitled to judgment for such
amount. If any such shareholder should be a party to a proceeding under
subsection (g) of this section, the court in such proceeding shall upon motion
of either the corporation or such shareholder dismiss the proceeding with
respect to such shareholder.

   (g) At any time during the period of sixty days after the date the
corporation is obliged to make an offer under subsection (d) of this section,
the corporation, or any shareholder who has made a demand to purchase shares
under subsection (b) of this section and who has not accepted the offer made by
the corporation and acting in the name of the corporation, may file a petition
in the superior court for the judicial district where its principal office is
located, or before any judge thereof, praying that the value of the shares of
such shareholders be found and determined. All shareholders making demand under
subsection (b) of this section who have not accepted the offer made by the
corporation, wherever residing, shall be made parties to the proceeding as an
action against their shares quasi in rem. A copy of the petition shall be served
on each such shareholder who is a resident of this state and shall be served by
registered or certified mail on each such shareholder who

                                       2
<PAGE>
 
is an nonresident. Service on nonresidents shall also be made by publication as
provided by law. The jurisdiction of the court shall be plenary and exclusive.
All shareholders who are parties to the proceeding shall be entitled to judgment
against the corporation for the amount of the fair value of their shares as of
the day prior to the date on which notice of the proposed corporate transaction
was mailed, exclusive of any element of value arising from the expectation or
accomplishment of such corporate transaction. The court may, if it so elects,
appoint one or more persons as appraisers to receive evidence and recommend a
decision on the question of fair value. The appraisers shall have such power and
authority as shall be specified in the order of their appointment or an
amendment thereof. The court shall by its judgment determine the fair value of
the shares of the shareholders entitled to payment therefor and shall direct the
payment of such value, together with interest, if any, as hereinafter provided,
to the shareholders entitled thereto. The judgment may include an allowance for
interest at such rate as the court may find to be fair and equitable in all the
circumstances, from the date notice of the proposed corporate transaction was
mailed to the date of payment. The costs and expenses of any such proceeding
shall be determined by the court and shall be assessed against the corporation,
but all or any part of such costs and expenses may be apportioned and assessed
as the court may deem equitable against any or all shareholders who are parties
to the proceeding to whom the corporation has made an offer to pay for the
shares if the court finds that the action of such shareholders in failing to
accept such offer was arbitrary or vexatious or not in good faith. Such expenses
shall include reasonable compensation for and reasonable expenses of the
appraisers, but shall exclude the fees and expenses of counsel for and experts
employed by any party; but if the fair value of the shares as determined
materially exceeds the amount which the corporation offered to pay therefor, or
if no offer was made, the court in its discretion may award to any shareholder
who is a party to the proceeding such sum as the court may determine to be
reasonable compensation to any expert or experts employed by the shareholder in
the proceeding.

   (h) Any judgment entered under subsection (f) or (g) of this section shall be
enforceable as other decrees of the superior court may be enforced and shall be
payable only upon and concurrently with the surrender to the corporation of the
certificate or certificates representing the shares for which payment is due,
duly endorsed for transfer. Upon payment of any such judgment, the shareholder
shall cease to have any interest in such shares. The liability to pay for shares
or to pay damages imposed by this section on a corporation extends to the
successor corporation which acquires the assets of the predecessor, whether by
merger, consolidation or sale of assets for securities. Shares acquired by a
corporation pursuant to payment of the agreed value therefor or to payment of
the judgment entered therefor, as in this section provided, may be held and
disposed of by such corporation as in the case of other treasury shares, unless
in the case of a merger or consolidation the plan of merger or consolidation
otherwise provides.

   (i) If a demand to purchase shares under subsection (b) of this section is
withdrawn upon consent, or if the proposed corporate action is abandoned or
rescinded or the shareholders revoke the authority to effect such action, or if
no demand or petition for the determination of fair value by a court has been
made or filed within the time provided in this section, or if a court of
competent jurisdiction determines that such shareholder is not entitled to the
relief provided by this section, then the right of such shareholder to be paid
the fair value of his shares shall cease and his status as a shareholder shall
thereupon be restored.

                                    PART II
                    INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.  INDEMNIFICATION OF OFFICERS AND DIRECTORS.

   Section 145 of the DGCL allows the corporation's Board of Directors to
indemnify officers and directors for certain liabilities arising from their
position as officer or director of the corporation if such person acted in good
faith and in a manner he reasonably believed "not opposed to" the best interests
of the corporation. The DGCL requires indemnification by the corporation in any
such action in which the officer or director has been successful on the merits.
The DGCL indemnification provision is non-exclusive of other rights to which
prospective indemnitees may be entitled under any by-law, agreement, vote of
stockholders or otherwise.

   Article VIII of Aquarion's by-laws provides for indemnification of its
officers, directors, employees and other agents to the maximum extent permitted
by Delaware law.

   The Company has also purchased directors' and officers' liability insurance
covering certain liabilities incurred by such persons in connection with the
performance of their duties.

ITEM 22.  UNDERTAKINGS.

  (a) The undersigned registrant hereby undertakes:

  (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:

   (i) To include any prospectus required by section 10(a)(3) of the Securities
       Act of 1933;

   (ii) To reflect in the prospectus any facts or events arising after the
        effective date of the registration statement (or the most recent post-
        effective amendment thereof) which, individually or in the aggregate,
        represent a fundamental change in the information set forth in the
        registration statement;

   (iii) To include any material information with respect to the plan of
         distribution not previously disclosed in the registration statement or
         any material change to such information in the registration statement;

  (2) That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

  (3) To remove from registration by means of a post-effective amendment any of
the securities being registered which remain unsold at the termination of the
offering.

  (b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

  (c) Insofar as indemnification of liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

  (d) The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the Prospectus pursuant to
Items 4, 10(b), 11 or 13 of this Form, within one business day of receipt of
such requests, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the Registration Statement through the
date of the responding to the request.

  (e) The undersigned Registrant hereby undertakes to supply by means of a post-
effective amendment all information concerning a transaction, and the company
being acquired involved therein, that was not the subject of and included in the
Registration Statement when it became effective.
