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 not less than $2,600,000 (the "Purchase Price"), which
represents the amount of $3.5 million reduced by the amount of certain
transaction costs, including a payment to an officer of NCC (see "Conflicts of
Interest"), and certain indebtedness of NCC and its subsidiaries to be paid or
assumed by BHC, will be issued by Aquarion in connection with the Asset Sale.
The Purchase Price may be increased to the extent that NCC or its subsidiaries
pay certain of their respective indebtedness before the consummation of the
Asset Sale. However, it is not anticipated that such repayments will aggregate
more than approximately $60,000 in amount. (See "Proposed Acquisition--
Acquisition Agreement--Principal Provisions"). 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.    
    
  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. Ten percent of the shares of Aquarion Common Stock issued as
payment of the Purchase Price shall be paid to an escrow agent to establish
an escrow fund. Escrow shares not applied to the payment of indemnification
claims BHC may have against NCC will be distributed to the former holders of the
Class B Common Stock upon termination of the escrow. See "Proposed Acquisition--
Acquisition Agreement--Escrow Fund."      
    
  Pursuant to the Plan of Liquidation and the Amendment, NCC will be liquidated
(the "Liquidation") and 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 plus accrued but unpaid dividends on the Class A
Common Stock to the date of the liquidating distribution, 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. It is estimated that the initial liquidating distribution will be
made to shareholders of NCC approximately four months after the closing date of
the Asset Sale. See "Plan of Liquidation." The distribution to holders of Class
B Common Stock will be reduced to the extent that (i) shares of Aquarion Common
Stock must be applied to the claims of creditors or to the expenses of
liquidation or (ii) the per share payment to NCC shareholders, if any, who
exercise dissenters' rights of appraisal, exceeds the per share payment to non-
dissenting NCC shareholders. See "Plan of Liquidation."    
    
  Neither the NCC Board of Directors nor the Aquarion Board of Directors sought
an opinion of an investment bank or other outside party as to the fairness of
the transaction from a financial point of view to the shareholders of NCC or to
Aquarion. Two of the eight directors of NCC who approved the Acquisition had
certain potential conflicts of interest. See "Proposed Transaction--Background
of the Transaction," "NCC's Reasons for the Transaction; Recommendation of NCC's
Board of Directors," "Aquarion's Reasons for the Transaction," and "Conflicts of
Interest."

  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 each of the proposals.     
    
  The Asset Sale and the Liquidation present certain risks to shareholders
of NCC and each shareholder is urged to read the section entitled "Risk Factors"
contained in the Prospectus/Proxy Statement.     
    
  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 directors of NCC intend to vote FOR the
proposals in our capacity as shareholders of NCC, and recommend that all other
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. IF
YOU HOLD SHARES OF CLASS A COMMON STOCK AND CLASS B COMMON STOCK, YOU HAVE
RECEIVED A SEPARATE PROXY WITH RESPECT TO EACH CLASS OF SHARES.     

                                           Sincerely yours,

                                           _______________________________

                                           Title:   President

                                PROXY STATEMENT

                             THE NEW CANAAN COMPANY
    
                     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 wholly-owned
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, no par value (the "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 a specified
liability of NCC in an amount not to exceed $130,000 and will transfer to NCC
shares of Aquarion Common Stock with a value of not less than $2,600,000 (the
"Purchase Price"), which represents the amount of $3,500,000 reduced by the
amount of certain of NCC's transaction costs, including a payment to an officer
of NCC (see "Conflicts of Interest"), and certain indebtedness of NCC and its
subsidiaries to be paid or assumed by BHC. The Purchase Price may be increased
to the extent that NCC or its subsidiaries pay certain of their respective
indebtedness before the consummation of the Acquisition. However, it is not
anticipated that such repayment will aggregate more than approximately $60,000
in amount. Ten percent of the shares of Aquarion Common Stock issued as payment
of the Purchase Price will be paid to an escrow agent to establish an escrow
fund. Escrow shares not applied to the payment of indemnification claims BHC may
have against NCC 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. See "Proposed Acquisition--Acquisition Agreement--Principal
Provisions" and "Proposed Acquisition--Acquisition Agreement--Escrow Fund." 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 dissolving NCC (the
"Liquidation") and distributing the Aquarion Common Stock received as the
Purchase Price, after adequate provision has been made for payments to any
creditors of NCC, to the holders of NCC common stock (the "NCC Shareholders"),
in accordance with the provisions of NCC's Certificate of Incorporation, the
Plan of Liquidation and the Connecticut Stock Corporation Act. The initial
liquidating distribution will not be made by NCC until at least four months from
the date that the Certificate of Dissolution of NCC is filed with the
Connecticut Secretary of State. See "Plan of Liquidation." 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 plus accrued but unpaid dividends on
the Class A Common Stock to the date of the liquidating distribution, and the
balance will be paid to the holders of the Class B Common Stock, no par value,
of NCC (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.
The distribution to holders of Class B Common Stock will be reduced to the
extent that (i) shares of Aquarion Common Stock must be applied to the claims of
creditors or to the expenses of liquidation or (ii) the per share payment to NCC
Shareholders, if any, who exercise dissenters' rights of appraisal, exceeds the
per share payment to non-dissenting NCC Shareholders. See "Plan of
Liquidation."    
<PAGE>
 
    
  Neither the NCC Board of Directors nor the Aquarion Board of Directors sought
an opinion of an investment bank or other outside party as to the fairness of
the transaction from a financial point of view to the NCC shareholders or to
Aquarion. Two of the eight directors of NCC who voted to approve the Acquisition
had certain conflicts of interest. See "Proposed Transaction--Background of the
Transaction", "NCC's Reasons for the Transaction, Recommendation of NCC's Board
of Directors", "Aquarion Reasons for the Transaction" and "Conflicts of
Interests."    
    
  NCC Shareholders who dissent from the Acquisition and Plan of Liquidation
("Dissenting Shareholders") 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 by NCC is
dependent on the trading price of Aquarion Common Stock on the New York Stock
Exchange ("NYSE") for the 30 business days beginning with the 45th business day
prior to the closing of the Acquisition.    
    
  This Prospectus/Proxy Statement relates to the distribution of shares of
Aquarion Common Stock in the Liquidation and on termination of the Escrow
Agreement. This Prospectus/Proxy Statement also relates to sales of shares of
Aquarion Common Stock by either (i) the escrow agent in order to provide funds
for the payment of indemnification claims, if any, which BHC or its affiliates
may have for certain liabilities arising from the Acquisition or (ii) NCC to
provide funds for expenses of liquidation, claims of creditors, or payments to
Dissenting Shareholders, if any. See "Proposed Acquisition--Acquisition
Agreement--Escrow Fund", "Plan of Liquidation" and "Rights of Dissenting
Shareholders."

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.

                      PROSPECTUS/PROXY STATEMENT SUMMARY
    
  The following summary is qualified in its entirety by information, copies of
documents and statutes, and financial statements appearing elsewhere in this
Prospectus/Proxy Statement and the information incorporated herein by reference.

    
Matters to be Considered    
 at the Special Meeting....  This Prospectus/Proxy Statement relates (i) to the
                             proposed acquisition, pursuant to the Acquisition
                             Agreement, by BHC of substantially all the assets
                             of NCC in return for the repayment of certain
                             indebtedness of NCC in an amount not to exceed
                             $130,000 and the transfer to NCC of Aquarion Common
                             Stock with a value, calculated in accordance with
                             the Acquisition Agreement, equal to not less than
                             $2,600,000 (the "Purchase Price"), which represents
                             the amount of $3,500,000 reduced by certain
                             transaction costs and indebtedness of NCC and its
                             subsidiaries to be paid or assumed by BHC, (ii) the
                             adoption 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 and (iii) the
                             adoption by NCC of a Plan of Liquidation pursuant
                             to Section 368(a)(1)(C) of the Internal Revenue
                             Code. The Purchase Price may be increased to the
                             extent that NCC or its subsidiaries pay certain of
                             their respective indebtedness before the
                             consummation of the Acquisition. However, it is not
                             anticipated that such repayment will aggregate more
                             than approximately $60,000 in amount. See "Proposed
                             Acquisition--Acquisition Agreement--Principal
                             Provisions." Ten percent of the shares of Aquarion
                             Common Stock issued as payment of the Purchase
                             Price shall be paid by BHC to an escrow agent for
                             an escrow fund established pursuant to the
                             Acquisition Agreement. Upon completion of the sale
                             of substantially all of its assets, NCC will
                             proceed with the liquidation of NCC (the
                             "Liquidation"). Pursuant to the Plan of Liquidation
                             and the Amendment, upon the dissolution of NCC, (i)
                             provision will be made for all liabilities of NCC,
                             (ii) holders of Class A Common Stock will receive,
                             for each share of Class A Common Stock, shares of
                             Aquarion Common Stock with a value equal to $35.00
                             plus accrued but unpaid dividends on the Class A
                             Common Stock to the date of the liquidating
                             distribution, and (iii) the holders of Class B
                             Common Stock shall receive the balance of the
                             Purchase Price (less possible deductions described
                             below) pro rata based on each such holder's
                             ownership interest in Class B Common Stock
                             immediately prior to the Liquidation. The
                             distribution to holders of Class B Common Stock
                             will be reduced to the extent that (i) shares of
                             Aquarion Common Stock must be applied to the claims
                             of creditors or to the expenses of liquidation or
                             (ii) the per share payment to Dissenting
                             Shareholders, if any, exceeds the per share payment
                             to non-dissenting NCC Shareholders. At the present
                             time, NCC is only aware of one claim against the
                             shares held for liquidating distributions. Pursuant
                             to a Settlement Agreement with the Connecticut
                             Department of Public Utility Control (the "DPUC"),
                             NCC is obligated to pay costs and expenses
                             estimated to be approximately $30,000 incurred by
                             NCWC and an employee of NCWC in connection with a
                                 
                                       7
<PAGE>
 
    
                             proceeding by the DPUC against NCWC. See "Plan of
                             Liquidation" and "Rights of Dissenting
                             Shareholders." Escrow Shares that are not applied
                             to the payment of indemnification obligations under
                             the Acquisition Agreement 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.
                             The expenses of the administration of the Escrow
                             Fund (as hereinafter defined) will be paid by
                             Aquarion and will not further reduce the amount
                             distributable to holders of Class B Common Stock as
                             part of the liquidation.        

                             This Prospectus/Proxy Statement also relates to
                             resales of shares of Aquarion Common Stock by

                             and conditions of the Acquisition.

                             an amount not to exceed $130,000 and Aquarion

                             assumed by BHC in cash at the closing

                             have agreed that the Deductions from the

                             in a Purchase Price of not less than $2,600,000.
                             The Purchase Price may be greater than that amount
                             to the extent that NCC or its subsidiaries pay

                             not anticipated that such repayments will
                             aggregate more than approximately $60,000

                             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 Closing Date (as
                             hereinafter defined). 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
                             Acquisition Agreement also provides that 10% of the
                             Aquarion Common Stock to be issued to NCC in
                             payment of the Purchase Price will be transferred
                             to an escrow agent (the "Escrow Agent") to
                             establish an escrow fund for a period which will
                             terminate on the earlier of the first anniversary
                             of the Closing Date and the date that audited
                             financial statements of BHC for the year ended
                             December 31, 1995 are available, which escrow fund
                             will be applied to obligations to indemnify BHC and
                             its affiliates against certain liabilities that
                             might result from the consummation of the
                             Acquisition (the "Escrow Fund").    
    
                             Hypothetical Exchange Ratios. The following table
                             sets forth the number of shares of Aquarion Common
                             Stock that a shareholder of NCC would receive for
                             each share of Class A Common Stock and Class B
                             Common Stock on the basis of different assumed
                             average market prices for Aquarion Common Stock,
                             as calculated pursuant to the Acquisition
                             Agreement. The table does not give effect to any
                             diminution of the number of shares receivable by
                             holders of Class B Common Stock in the event that
                             provision must be made for claims of creditors
                             (other than certain costs of a regulatory
                             proceeding estimated to be approximately $30,000 -
                             see "Plan of Liquidation") or for the costs and
                             expenses of the Liquidation or if the per share
                             payment to Dissenting Shareholders exceeds the per
                             share payment to non-dissenting NCC Shareholders.

                             Property Exchange Agreement. An integral part of
                             the Acquisition is a three-cornered property
                             exchange (the "Property Exchange") pursuant to a

                             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 $305,000 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
                             amendments thereto are annexed as Exhibits E, F and
                             G to this Prospectus/Proxy Statement and are
                             incorporated herein by reference. The description
                             herein of the Property Exchange Agreement 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. Certain of
                             the conditions specified in clause (iii) have been
                             satisfied or waived, and the condition specified in
                             clause (v) has been satisfied. It is anticipated
                             that the remaining conditions specified in clause
                             (iii) and the conditions specified in clause (iv)
                             will be satisfied or waived before the Closing Date
                             (as defined below).    

                             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 Acquisition 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 implement the Plan
                             of Liquidation by dissolving NCC. In order to
                             effectuate the dissolution, NCC will give notice
                             to all known creditors and will pay or make
                             adequate provision for any liabilities for which a
                             creditor makes a claim. Under Connecticut law, in
                             order to bar any potential creditors' claims, at
                             least four months must elapse between the
                             commencement of the liquidation of NCC and the
                             distribution of Aquarion Common Stock to holders of
                             Class A Common Stock and Class B Common Stock.
                             Holders of Class A Common Stock will then receive,
                             for each share of Class A Common Stock, shares of
                             Aquarion Common Stock with a value equal to $35.00
                             plus accrued and unpaid dividends thereon to the
                             date of the liquidating distribution. The number of
                             shares of Aquarion Common Stock distributable to
                             holders of Class A Common

                             Stock in respect of their liquidation preference
                             will be calculated using the value of the Aquarion
                             Common Stock as calculated pursuant to the
                             Acquisition Agreement. The remaining shares of
                             Aquarion Common Stock, after provision is made for
                             creditors, any payments to Dissenting Shareholders
                             and the expenses of the Liquidation, will be
                             distributed to holders of Class B Common Stock.
                             Expenses of the Liquidation will first be paid from
                             dividends received on the Aquarion Common Stock and
                             thereafter by selling shares of Aquarion Common
                             Stock received as Purchase Price. Payments to
                             creditors and dissenting shareholders will be made
                             by NCC selling shares of Aquarion Common stock
                             received as Purchase Price. To the extent that
                             shares of Aquarion Common Stock must be sold to pay
                             claims of creditors or the expenses of the
                             Liquidation, the number of shares of Aquarion
                             Common Stock distributable to holders of Class B
                             Common Stock will be reduced. At the present time,
                             NCC is only aware of one claim against the shares
                             held for liquidating distributions. Pursuant to a
                             Settlement Agreement with the DPUC, NCC is
                             obligated to pay costs estimated to be
                             approximately $30,000 incurred by NCWC and an
                             employee of NCWC in connection with a proceeding by
                             the DPUC against NCWC. To the extent that the per
                             share payment to Dissenting Shareholders exceeds,
                             the per share payment to non-dissenting NCC
                             Shareholders, the effect will be to reduce the
                             number of shares of Aquarion Common Stock received
                             by 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 by NCC in the liquidation or by the
                             Escrow Fund. Cash will be paid in lieu of
                             fractional shares and such cash will be obtained by
                             liquidating a sufficient number of shares of
                             Aquarion Common Stock to make such payments. 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 Fund will not
                             be transferable by the former holders of Class B
                             Common Stock.    
    
 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 the liquidating distribution.
                             After the holders of the Class A Common Stock are
                             paid in full, the remaining assets are to be
                             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 and to provide for the
                             method of valuing the shares of Aquarion Common
                             Stock to be distributed. In order for the
                             Acquisition and the Liquidation to receive the tax
                             treatment described below under the caption
                             "Federal Income Tax Consequences of the
                             Acquisition, Property Exchange and Liquidation," it
                             is necessary that shares of Aquarion Common Stock
                             be distributed in the Liquidation.    
    
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 tax-deferred
                             transaction; and the economies of scale in
                             operating NCWC and RWSC  that should result from
                             the Acquisition (such as reduced operating
                             expenses and lower costs of borrowing). The NCC
                             Board of Directors did not seek an opinion of an
                             investment bank or other outside party as to the
                             fairness of the transaction from a financial point
                             of view to the shareholders of NCC.     
    
                             Messrs. Glidden and McLinden have certain
                             interests in the transactions other than their
                             interests as directors or officers of NCC. Mr.
                             McLinden is entitled to receive a cash payment
                             that is contingent upon the Acquisition Closing
                             and Mr. Glidden will be repaid the outstanding
                             principal balance of promissory notes payable to
                             him by NCC and its subsidiaries at the Acquisition
                             Closing as required by the DPUC. Messrs. McLinden
                             and Glidden participated in the discussions of,
                             and voted in favor of the Acquisition, the
                             Amendment and the Plan of Liquidation, however,
                             the payment to Mr. McLinden was not authorized by
                             the Board of Directors of NCC until after the
                             Acquisition was approved by the Board and the
                             promissory notes held by Mr. Glidden are payable
                             on demand or on or before June 30, 1995. "See

Approvals of the Boards of   
 Directors of BHC and        
 Aquarion..................  The Aquarion and BHC Boards have approved the
                             Acquisition and believe 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
                             subsidiary, SWC. 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. The Boards of Aquarion and BHC
                             did not seek an opinion of an investment banker or
                             other outside party as to the fairness of the
                             Acquisition from a financial point of view to
                             Aquarion and BHC. See "Proposed Transaction--
                             Background of the Transaction" and "Aquarion's
                             Reasons for the Transaction."

                             will have the right to be paid the value,
                             determined as provided in the statute, of all of
                             his or her shares of NCC Common Stock upon
                             compliance with the provisions of the Dissenters'
                             Rights Statute. The written objection must be
                             in addition to and separate from any proxy or vote
                             against the Acquisition and the Plan of

                             shareholder's NCC Common Stock is not voted in
                             favor of the Acquisition and, in the case of

                             Shareholders who are affiliates of NCC at the time
                             of the Special Meeting will be able to resell
                             shares of Aquarion Common Stock in compliance with
                             the volume and manner of sale restrictions of Rule
                             144 under the Securities Act. 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 Closing Date. NCC currently
                             anticipates that the first liquidating
                             distribution of NCC's net assets will occur after
                             the expiration of such four-month period, and
                             prior to such liquidation NCC will be the
                             registered holder of all of the shares of Aquarion
                             Common Stock representing the Purchase Price (less
                             shares held in the Escrow Fund). NCC has no
                             current intention of disposing of such shares
                             other than pursuant to the Plan of Liquidation
                             in order to pay creditors, Dissenting
                             Shareholders, if any and the expenses of
                             liquidation, if necessary. At the present time,
                             NCC is only aware of one claim against the shares
                             held for liquidating distributions. Pursuant to a
                             Settlement Agreement with the DPUC, NCC is
                             obligated to pay costs estimated to be
                             approximately $30,000 incurred by NCWC and an
                             employee of NCWC in connection with a proceeding
                             by the DPUC against NCWC. Aquarion has agreed to
                             permit the Escrow Agent and NCC to sell shares of
                             Aquarion Common Stock during the initial
                             four-month period following the Closing Date to
                             satisfy, in the case of the Escrow Agent,
                             indemnification claims which BHC or its affiliates
                             might have for certain liabilities resulting from
                             the Acquisition, and, in the case of NCC, expenses
                             of the Liquidation, claims of creditors or
                             payments to Dissenting Shareholders, if any.      
    
Certain Federal Income Tax   It is intended that the Acquisition and the Plan
 Consequences..............  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      

                                       17

                             result of the Asset Sale, and (2) each NCC
                             Shareholder who receives Aquarion Common Stock in a
                             liquidating 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 (collectively, the "Reservoir") from NCWC
                             to STD. The DPUC issued such approvals on June 30,
                             1993, but subsequently reopened its approval
                             proceeding in order to address, among other
                             matters, 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 that abuts
                             the Reservoir (the "Land Sale") and NCWC's request
                             for clarification of the responsibility of NCC to
                             repay said loan in light of the Acquisition
                             Agreement. No final decision has yet been issued in
                             the reopened proceeding and the Acquisition can not
                             take place until such a decision is issued. Such a
                             final decision is currently expected to be rendered
                             on April 19, 1995. The parties anticipate that the
                             Land Sale will not be consummated prior to the
                             Closing of the Acquisition. BHC and NCC have agreed
                             that the Acquisition will close whether or not the
                             Land Sale and the retirement of NCWC debt take
                             place prior to the Closing. However, the effect on
                             the Acquisition of any other terms and provisions
                             of the DPUC's final decision, not contemplated by
                             the agreement between BHC and NCC, such as a ruling
                             that NCC make provision for the repayment of the
                             loan or reduce the Purchase Price in the amount of
                             the shortfall, cannot be predicted. In addition,
                             the Closing Date as set forth in the Acquisition
                             Agreement and Property Exchange Agreement has only
                             been extended by the DPUC to June 30, 1994. The
                             parties have requested that the Closing Date be
                             extended by the final DPUC decision to correspond
                             to the June 30, 1995 Closing Date currently agreed
                             to by the parties.    
    
                             The transfer of the reservoir to STD as a raw
                             drinking water supply source must be approved by
                             the Connecticut Department of Public Health and
                             Addiction Services ("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
                             Reservoir transfer takes place, of watershed and
                             non-watershed land. In the event that DPHAS does
                             not issue the permit, STD would not be able to
                             purchase the Reservoir and it is unlikely that the
                             Acquisition would occur. A diversion permit from

                             the Connecticut Department of Environmental
                             Protection ("DEP") is required in order for STD to
                             use water from the 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 the
                             petitioners have filed an appeal from the DEP
                             ruling in Connecticut State Superior Court. 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 unless the matter
                             is returned to DEP jurisdiction prior to the
                             Property Exchange Closing. See "Proposed
                             Acquisition--Regulatory Approvals."

                               RISK FACTORS     
             
    
  NCC Shareholders should consider carefully, in addition to the other
information contained in this Prospectus/Proxy Statement, the following risk
factors relating to the Acquisition and the Liquidation.      

    
PRICING PERIOD      
    
  The aggregate number of shares of Aquarion Common Stock which will constitute
the Purchase Price will be determined by valuing the shares 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 30 consecutive
business days commencing on the 45th business day prior to the date of the
Closing of the Acquisition (the "Pricing Period"). The exact number of shares to
be issued is therefore not yet determinable, although the Acquisition is subject
to the condition that no more than 140,000 shares or less than 87,500 shares be
issued by Aquarion as payment of the Purchase Price. In addition, the parties
intend to close the Acquisition on the date of the Special Meeting or as soon
thereafter as possible. However, if the Closing is delayed, the pricing period
for the Aquarion Common Stock would also be deferred which could change the
number of shares as payment of the Purchase Price issuable from the number which
would be issuable if the Acquisition Closing occurred on the date of the Special
Meeting.      

    
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 the Reservoir from NCWC to STD. The DPUC
issued such approvals on June 30, 1993, but subsequently reopened its approval
proceeding in order to address, among other matters, the ability of NCWC to
repay an outstanding loan of $1.25 million with the proceeds of the Land Sale
and NCWC's request for clarification of the responsibility of NCC to repay said
loan in light of the Acquisition Agreement. No final decision has yet been
issued in the reopened proceeding and the Acquisition can not take place until
such a decision is issued. Such a decision is currently expected to be rendered
on April 19, 1995. The parties anticipate that the Land Sale will not be
consummated prior to the Closing of the Acquisition. BHC and NCC have agreed
that the Acquisition will close whether or not the Land Sale and the retirement
of NCWC debt take place prior to the Closing. However, the effect on the
Acquisition of any other terms and provisions of the DPUC's decision, not
contemplated by the agreement between BHC and NCC, such as a ruling that NCC
make provision for the repayment of the loan or reduce the Purchase Price in the
amount of the shortfall, 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 Reservoir transfer takes place, of watershed and non-watershed land. In
the event that DPHAS does not issue the permit, STD would not be able to
purchase the Reservoir and it is unlikely that the Acquisition would occur. A
diversion permit from the DEP is required in order for STD to use water from the
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 the petitioners have filed an appeal from the DEP ruling in
Connecticut State Superior Court. 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 unless
the matter is returned to DEP jurisdiction prior to the Property Exchange
Closing. See "Proposed Acquisition--Regulatory Approvals."      

    
CREDITORS' CLAIMS; DISSENTERS' SHARES      
    
  In order to effect the Liquidation, NCC will give notice to all known
creditors and will pay or make adequate provision for any liabilities for which
a creditor makes a claim. To the extent that shares of Aquarion Common Stock
must be used to pay claims of creditors, the number of shares of Aquarion Common
Stock distributable to holders of Class B Common Stock will be reduced. At the
present time, NCC is only aware of one claim against the shares of Aquarion
Common Stock that will be held for liquidating distributions. Pursuant to a
Settlement Agreement with the DPUC, NCC is obligated to pay costs estimated to
be approximately $30,000 incurred by NCWC and an employee of NCWC in connection
with a proceeding brought by the DPUC against NCWC. In addition, NCC
Shareholders who dissent from the Acquisition and Plan of      

                                       20

Liquidation have certain rights of appraisal pursuant to Connecticut law. See,
"Rights of Dissenting Shareholders." Payments to Dissenting Shareholders will be
made by liquidating shares of Aquarion Common Stock received as Purchase Price.
To the extent that the per share payment to Dissenting Shareholders exceeds the
per share payment receivable by non-dissenting shareholders, the effect will be
to reduce the number of shares of Aquarion Common Stock received by holders of
Class B Common Stock in the Liquidation.      
    
LIQUIDATION PROCEDURE      
    
  Under Connecticut law, in order to bar any potential creditors' claims, at
least four months  must elapse between the commencement of the liquidation of
NCC and the distribution of Aquarion Common Stock to holders of Class A Common
Stock and Class B Common Stock. During this period, the market price of Aquarion
Common Stock will fluctuate. The number of shares of Aquarion Common Stock to be
received by each holder of Class A Common Stock in respect of the liquidation
preference will be calculated using the value of the Aquarion Common Stock over
the Pricing Period as calculated pursuant to the Acquisition Agreement. Holders
of Class A Common Stock will receive shares of Aquarion Common Stock with a
value, calculated over the Pricing Period in accordance with the Acquisition
Agreement, equal to $35.00 per share of Class A Common Stock, plus all accrued
but unpaid dividends on such shares to the date of the liquidating distribution.
As a result, the value of the shares of Aquarion Common Stock received for each
share of Class A Common Stock could be less than, equal to or greater than the
market value of the Aquarion Common Stock on the date of the liquidating
distribution.

  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.
    
 As of December 31, 1994, there were 7,207 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.

                                       24
<PAGE>
 
  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 December 31, 1994, the applicable
restrictions would have permitted payment of additional dividends on Aquarion's
common stock of up to $35,000,000. This amount, adjusted by results for 1995,
will be unrestricted under the Aquarion Notes and the Revolving Credit Agreement
for payment of dividends in 1995.    

  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. 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 on each 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. The Board of Directors of NCC
declared a dividend equal to $1.00 per share of Class A Common Stock on December
15, 1994. Such dividend was paid on February 15, 1995. The Board of Directors of
NCC declared a dividend equal to $.25 per share of Class A Common Stock on March
21, 1995, which has not yet been paid. 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 shares of Class B Common Stock. Furthermore, after
paying the dividends on the outstanding Class A Common Stock, the Class A Common
Stock as a class is 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 March 31, 1995, 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, BHC acquired Stamford
Water Company ("SWC") and shortly thereafter completed negotiations with public
water suppliers in lower Fairfield County, including  NCWC, to construct a
regional pipeline (the "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 SWC 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 

                                       27
<PAGE>
 
    
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.     
    
 In June 1983, Mr. A. Leland Glidden, then President of NCWC, asked BHC to
submit a proposal to construct a regional pipeline which would make BHC's water
supply available to NCWC, whose reservoir was not in compliance with applicable
water quality standards. Mr. Glidden also invited BHC to submit a proposal for
the acquisition of NCWC's operating assets. After BHC completed negotiations    
with NCWC and other public water suppliers in lower Fairfield County in 1984 for
the construction of the Regional Pipeline, BHC's then President, Mr. William S.
Warner, and its then Senior Vice President and General Counsel, Mr. Anthony M.
Macleod, met with Mr. Glidden and NCC Board members Alex R.M. Boyle and Germaine
Glidden to ascertain the extent of NCC's interest in disposing of NCWC and to
identify basic issues. Mr. Warner submitted BHC's first conceptual proposal to
NCC for the acquisition of NCWC in the spring of 1985. The proposal entailed
BHC's purchase of all assets other than NCWC's reservoir and related property
consisting of approximately 173 acres of watershed land, a dam, wells and
easements (collectively, the "Reservoir") for a cash payment to NCC of
$1,030,000, BHC's assumption of liabilities for customer advances and
contributions-in-aid-of-construction amounting to $616,813 and an equal sharing
of the net proceeds from the sale of surplus Class III land among NCWC's
shareholders, NCWC's ratepayers and BHC, with NCWC's shareholders guaranteed a
minimum of $400,000 of such proceeds.    
    
  Following a meeting on June 14, 1985 among Messrs. Boyle and W. Wilson
Garey (another NCC Board member), and Messrs. Warner, Macleod, Jack E. McGregor,
and James S. McInerney, Jr., the then President of SWC, NCWC proposed that the
cash payment initially proposed as $1,030,000 be increased to $1,500,000, that
BHC assume the cost of improvements related to the Regional Pipeline, and that
land sale proceeds be shared equally between NCWC's shareholder and customers of
the entire Bridgeport system. On August 1, 1985, BHC offered to increase the
cash payment to $1,400,000, plus the assumption of the costs of improvements to
the Regional Pipeline, and to share land sale proceeds up to $2,400,000 in a
manner which would provide 50% to customers and which, based on NCWC's 1984
appraisals, would provide NCWC's shareholders with a further $550,000 to
$1,000,000, with no guaranteed minimum share. On November 15, 1985, BHC modified
the proposal for sharing land sale proceeds to provide that NCWC would receive
25% of the first $1,600,000 of land sale proceeds, 50% of the next $1,600,000
and 25% of all net proceeds in excess of $3,200,000. NCC deferred a response,
indicating that NCWC had determined it should further investigate land issues.
         
  In May, 1986, Mr. Boyle called Mr. Warner to state NCWC's interest in resuming
negotiations. Mr. Warner suggested that BHC would purchase operating assets
only, with no premium over net book value, leaving land and the resolution of
any land-related issues to NCWC.     
    
  In the spring of 1987, as NCWC pursued its investigation of land issues, and
as it became doubtful that the Connecticut Department of Health Services (now
known as DPHAS) would permit abandonment of the Reservoir and the resulting
development of adjacent land, Messrs. Boyle and Macleod held several discussions
which addressed the difference between NCWC's expectations based on the
development value of its land and BHC's reluctance, due to utility ratemaking
considerations, to pay more than the net book value of NCWC's utility assets,
plus a modest premium. The concept of a sale of all of NCC's assets emerged as a
means of extending the premium to a larger asset base, thereby creating a
larger, non-taxable transaction involving RWSC and NCWC, including NCWC's land.
Even with a larger transaction including RWSC, however, BHC and NCC could not
agree upon a transaction price that was both satisfactory to BHC as a fair
measure of the value of NCWC and RWSC as utility operations and also acceptable
to NCC as fairly reflecting NCWC's landholdings.     
    
  In 1988, the Board of Directors of NCC appointed a special committee
consisting of Mr. Garey and Mr. Boyle to explore alternative possibilities for
the sale of NCC or its two subsidiaries. In addition to the prior discussions
with BHC, the committee entered into discussions with other potential acquirors
during 1988 and 1989.     
    
  In June of 1988, Mr. John M. Hiscock, the General Manager of the Second Taxing
District of the City of Norwalk, Connecticut ("STD"), a municipal water
supplier, indicated STD's interest in acquiring the Reservoir in order to meet
STD's       

                                       28
<PAGE>
 
    
need for additional water supply. Following discussions among Messrs. McInerney,
Macleod, Hiscock and Michael Lyons, then STD's attorney, BHC and STD agreed to
submit a joint proposal to purchase all of the assets of NCC whereby BHC would
acquire the transmission and distribution system of NCWC and RWSC, and STD would
acquire the Reservoir. STD's participation resolved questions relating to the
future use of the Reservoir and provided additional consideration which BHC
would not have been willing to pay.      
    
  On June 24, 1988, Messrs. McInerney and Macleod met with Messrs. Boyle and
Garey, who suggested that all assets of NCC could be sold to BHC for a price
between $7,000,000 and $8,000,000. The details and conditions of the joint offer
by BHC and STD to purchase the assets of NCC were discussed at a meeting among
Messrs. McInerney, Macleod, Hiscock and Lyons on September 13, 1988. By letter
dated December 14, 1988, BHC and STD offered to purchase the assets of NCWC,
excluding certain real property designated by the Department of Health Services
as Class III land, and the assets of RWSC for total consideration of $7,700,000,
consisting of both cash and the assumption of NCWC's tax-exempt Connecticut
Development Authority bonds in the principal amount of $1,400,000, subject to
several conditions pertaining in large part to STD's ability to utilize the
Reservoir as a water supply source having a safe yield of 600,000 gallons per
day. It was not the intention of BHC or STD to assume liabilities of NCC or its
subsidiaries, amounting to approximately $5,000,000.     
    
  By letter from Mr. Garey dated January 24, 1989, NCC responded that it was
agreeable to a net price in the range of $7,000,000 to $8,000,000 after
assumption by BHC and STD of all liabilities of NCC and its subsidiaries,
noting its belief that BHC's proposal did not adequately compensate NCC for the
replacement value of its assets and the value of its watershed land. NCC
refrained from making a specific counter offer until its year end 1988 audited
statements were available and it received the results of a land use study for
its Class III land. NCC also observed that the cash purchase of assets would
have disadvantageous tax consequences. BHC indicated that it would not pay such
a price and also assume liabilities. By letter dated May 9, 1989, Mr. Garey, on
behalf of NCC, further responded that NCC would accept consideration of
$3,725,000 in Aquarion stock for all assets of NCC, except for the Class III
land and development rights associated with Class I and II land. Half of the net
proceeds from the sale of the retained land would be remitted to BHC for rate
base reductions or rebates to NCWC ratepayers. The parties did not reach
agreement on this counter offer.     
    
  By letter dated September 12, 1989, NCC requested the submission of proposals
to purchase NCC. In addition to BHC, there were in September 1989 three other
serious bidders interested in acquiring the assets of NCC and each was asked to
submit their most favorable proposal in writing to NCC not later than October 1,
1989. Proposals were received from (1) BHC, (2) Ansonia-Derby Water Company, (3)
General Waterworks Corporation and (4) Dudley C. Philips - Municipal Entity. A
special meeting of the Board of Directors of NCC was called for October 21, 1989
for the purpose of considering these proposals.     
    
  BHC's proposal was submitted to Mr. Garey by letter dated September 30, 1989.
BHC offered NCC either (a) a cash price of $3,125,000 for a taxable acquisition
of shares of NCC or shares of NCWC and RWSC or (b) shares of Aquarion valued at
$2,925,000 in a tax deferred acquisition. BHC's offer was conditioned, among
other things, on a binding agreement between BHC and STD for STD's purchase of
the Reservoir from BHC for $2,000,000 and on various regulatory approvals,
including the grant of a diversion permit from the DEP allowing STD to take up
to 600,000 gallons of water per day from the Reservoir.     
    
  At the NCC Board meeting, Mr. Garey summarized the terms and conditions of
each proposal, written copies of which had been distributed to the Board. Mr.
Boyle had prepared, and he distributed at the meeting, a worksheet which
attempted to quantify and compare the financial aspects of each of the proposals
and their value to the shareholders of NCC. This worksheet also attempted to
compare certain non-financial considerations associated with each proposal.
Messrs. Garey and Boyle had come to the conclusion that, considering all the
factors, including price, the proposal made by BHC was the most promising
proposal and that of Dudley C. Philips the least promising. Mr. Garey explained
his reasons for reaching this conclusion and stated that he was concerned that
the DPUC might attempt to allocate a portion of the proceeds of the sale to
ratepayers, thereby reducing the portion of the purchase price to be received by
NCC. In connection with this concern, he also stated that since the total
consideration being offered by BHC for the operating water companies and the
Reservoir was far below the appraised value of the Reservoir alone, and that
since the BHC proposal provided that the Reservoir remain part of the public
water supply system, the shareholders of NCC should not suffer any further
diminution of value by virtue of such an allocation.     
    
  The Board then discussed the various proposals, with particular attention to
the BHC proposal. The Board also discussed how to enhance the prospects of
obtaining DPUC approval of the transaction on a basis that would be acceptable
to the Board      

                                       29
<PAGE>
 
    
and the shareholders. At the conclusion of these discussions, the
Board authorized Mr. Garey to proceed with negotiations with BHC for a potential
sale of the company.     
    
  On November 20, 1989, NCC elected the tax deferred option offered by BHC but
indicated that $2,925,000 was too low a price. BHC responded on January 11,
1990, increasing its offer to $3,250,000, subject to a reduction equal to the
amount of any allocation of proceeds from the transfer of the Reservoir made for
the benefit of ratepayers. This offer was not acceptable to NCC, and BHC revised
its offer by conditioning the transaction on regulatory treatment satisfactory
to both parties. On April 23, 1990, NCC returned a signed letter of intent to
BHC with respect to the proposed acquisition by BHC of all assets of NCC for
$3,250,000, to be paid in shares of Aquarion common stock, subject to conditions
that Aquarion would not be required to deliver more than 130,000 shares, nor
would NCC be required to accept fewer than 108,250 shares. STD would essentially
reimburse BHC for that portion of the price attributable to the Reservoir
through STD's payment of $2,000,000 for the Reservoir. Accordingly, the letter
of intent was conditioned upon STD's purchase of the Reservoir, the granting of
the Diversion Permit by DEP, the obtaining of construction and spillage
easements relating to the use of the Reservoir, various approvals from
governmental agencies, including satisfactory regulatory treatment of the
proceeds from the sale of the Reservoir, and due diligence reviews.    
    
  In order to defer the tax impact of the sale of the Reservoir, the parties
subsequently agreed that the Reservoir would be transferred to STD as part of a
non-taxable property exchange in which STD would pay $2,000,000 to the owners of
a commercial building (the "MELP Building") in Monroe, Connecticut, and the
owners would transfer the MELP Building to NCWC.    
    
  In Connecticut, utility companies are permitted to earn a return only on the
original cost, less depreciation, of assets used to provide utility service. The
appropriate rate of return is determined by the DPUC, and the earnings potential
of utility assets is based on their net book value. In determining the
consideration that could reasonably be paid for NCWC and RWSC as operating
utilities, BHC considered the net book value of the utility assets of NCWC and
RWSC based on 1989 financial statements, the water rates established for NCWC
and RWSC by the DPUC and the return that would be paid as dividends on shares of
common stock issued for the acquisition. These considerations limited the amount
BHC could pay to acquire NCWC and RWSC. However, STD's participation in the
transaction enabled BHC to increase the amount to be paid to $3,250,000. This
$2,000,000 increase reflected the estimated fair market value of the Reservoir
as a water supply source. Because STD is not regulated by the DPUC, it is not
obligated to carry the Reservoir at its historical original cost, and the
purchase of the Reservoir was less expensive than other alternative solutions to
STD's need for additional water supply.     
    
  While BHC would have preferred that STD buy the Reservoir directly from NCWC
for $2,000,000 and that BHC purchase the remaining NCWC operating assets and
RWSC from NCC for $l,250,000, that alternative would have created immediate tax
consequences and was therefore unacceptable to NCC. In order for the proposed
transaction to qualify for tax deferred treatment, the parties agreed that
Aquarion Common Stock would be used as consideration for the purchase. The
parties did not consider it appropriate to incur the expense of obtaining an
outside financial advisor given the relatively small size of the transaction and
given the special internal expertise each company possessed regarding utility
regulation in Connecticut.     
    
  The parties did not structure the transaction as a merger because NCC could
accomplish its tax-deferred transaction objective without a merger and a merger
would have exposed BHC's assets to the satisfaction of contingent or unknown
liabilities of NCC or its utility subsidiaries before BHC had gained sufficient
familiarity with NCC and the operations of its utility subsidiaries.     
    
  On May 15, 1990, Messrs. Garey, McLinden, McInerney and Macleod met with
Connecticut Assistant Attorney General Robert Golden and Eugene Koss of the
Office of Consumer Counsel ("OCC"), which represents the interests of ratepayers
in regulatory proceedings, in order to determine what regulatory concerns the
OCC might have and to determine whether the DPUC's regulatory approval could be
obtained in a simplified proceeding through a stipulation between the parties
and the OCC. It was subsequently determined that the parties would have to file
a complete application and initiate approval proceedings before a stipulation
could be considered.     
    
  In the summer of 1990, BHC determined that a property exchange would be
preferable to a cash sale of the Reservoir to STD. As STD had no property that
would be appropriate for an exchange, a search for suitable property for such an
exchange commenced. BHC decided that the MELP Building was appropriate and
commenced negotiations with the owners for a three way property exchange during
December of 1990.     

                                       30
<PAGE>
 
    
  In December, 1990, NCWC asked the DPUC for permission to extend the term of a
$1,250,000 loan from Citytrust Bank. In granting an extension, the DPUC stated
its expectation that NCWC would attempt to sell its surplus Class III land
consisting of approximately 44 acres and that NCWC would use the proceeds from
such sale to retire the loan. NCWC indicated that it would attempt to do so. The
loan subsequently was refinanced by the Village Bank & Trust Company ("Village
Bank") and the loan's maturity date has been extended several times in
anticipation of the Land Sale or the Acquisition Closing.     
    
  After identification of the MELP Building and the extension of the loan, the
parties began to negotiate and prepare the terms of definitive agreements for
the proposed acquisition and the property exchange. The negotiation of the
definitive agreements did not change any material terms of the letter of intent,
but instead generally added customary detail to the parties' understandings.
Such detail included closing formalities and documents, representations and
warranties by the parties, mutual indemnifications for breach of warranty or
misrepresentation, an escrow account, and closing conditions. See "Proposed
Acquisition." The concept of a property exchange rather than a cash sale of the
Reservoir was introduced after the letter of intent and is reflected in the
definitive agreements, together with the understanding regarding NCC's
liabilities reached by the parties during the regulatory approval proceedings.
         
  In June, 1991 an application for approval of the Acquisition and the
Property Exchange was filed with the DPUC, together with agreements in draft
form that had been negotiated by the parties. During the course of the
proceedings, NCWC was questioned extensively by DPUC staff regarding repayment
of its indebtedness, and BHC and NCC reached agreement on the repayment or
assumption of liabilities of NCC and its utility subsidiaries, including BHC's
assumption of NCC indebtedness of up to $130,000, which agreement was
incorporated into the Acquisition Agreement. BHC also indicated that if NCWC
could not sell its surplus Class III land prior to the closing of the
Acquisition, BHC would continue efforts to sell such land and would apply any
proceeds therefrom toward retirement of the $1,250,000 loan now held by Village
Bank. The foregoing agreements were reflected in the Acquisition Agreement,
dated as of September 2, 1992.     
    
  Because necessary regulatory approvals were not obtained prior to the
stated expiration date of December 31, 1992 in the Acquisition Agreement and
the Property Exchange Agreement, it was necessary to extend those agreements
while regulatory decisions were awaited. In March 1993, NCC stated that it would
not extend the agreements beyond May 1, 1993 without adjusting the purchase
price to reflect an improvement in its retained earnings since 1988. At such
time, the Closing Dates were extended to June 15, 1993 by the DPUC. Mr.
McInerney and Mrs. Janet M. Hansen, Senior Vice President and Chief Financial
Officer of Aquarion, subsequently met with Mr. McLinden and NCC's accountants,
Price Waterhouse, to review current financial statements and capital
improvements made by NCWC and RWSC since 1989. BHC later agreed to increase the
gross purchase price from $3,250,000 to $3,500,000 which increase was reflected
in an amendment to the Acquisition Agreement which also extended the Closing
Date until March 31, 1994.     
    
  The Acquisition Agreement, the Property Exchange Agreement and the
Liquidation, 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 NCWC, 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, certain actions were required of the parties by regulatory
authorities. See "Proposed Acquisition--Regulatory Approvals." In
addition, it has been necessary to amend both agreements to extend the date
on which such agreements would terminate if the Acquisition Closing or the
Property Exchange Closing had not occurred. Currently, the Closing Date must
occur on or before March 31, 1995 or the transactions may be
terminated. The parties have agreed to extend the termination date until June
30, 1995. The DPUC decision in effect only extended the Closing Date until June
30, 1994, however, the DPUC has been asked to further extend the deadline to
June 30, 1995. 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
material factors on which the Board based its determination, which are all of
the material factors which the Board deemed relevant, are described below. 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     

                                       31
<PAGE>
 
    
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,
which are described below, 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, and considers the exchange of investments to
be favorable, 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 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 Board
did not perform any quantifiable analysis in concluding that the exchange of
investments was favorable. The Board did, however, attempt to determine the
total number of shares of Acquisition Common Stock that would be received by NCC
Shareholders and determined that NCC would want the ability to terminate the
Acquisition Agreement if NCC would receive less than 87,500 shares of Aquarion
Common Stock as payment of the Purchase Price.     
    
  The NCC Board considered economic, financial and legal factors in reaching its
conclusion to approve and recommend the transactions. The economic factors
included the difficulties NCWC and RWSC were encountering in attempting to
operate their respective businesses profitably while attempting to comply with
an increasing number of laws and regulations affecting such businesses. This
included economic regulation by the DPUC, environmental regulation and health-
related regulation (including maintaining compliance with the Federal Safe
Drinking Water Act and its amendments). The costs of maintaining compliance with
such laws and regulations was becoming less and less economically feasible when
applied to revenues generated by companies the size of NCWC and RWSC. It was
also becoming apparent to the Board of NCC that small local water companies were
being acquired by larger water companies whose larger revenues allowed them more
effectively to absorb the costs of regulatory compliance.     
    
  The financial factors considered primarily related to whether the aggregate
purchase price to be received by NCC was fair. In addition, the NCC Board
considered the facts that the transaction would not have immediate tax
consequences for the NCC Shareholders, the NCC Shareholders would receive
securities with a more active trading market and that Aquarion had a record of
paying uninterrupted dividends on its capital stock. The legal factors
considered included the structure and form of the transactions and the effect
thereof on NCC Shareholders. The latter analysis included the fact that
different consideration would be paid to holders of Class A Common Stock and
Class B Common Stock in the Liquidation, and that the holders of Class A Common
Stock would receive the liquidation preference provided in NCC's Certificate of
Incorporation and no additional consideration.     
    
  The Board of NCC agreed to the request by BHC to include in the Acquisition
Agreement a covenant that NCC Shareholders would not sell their shares on the
market for a period of four months after the closing of the Acquisition. Given
the belief that most NCC Shareholders would hold the Aquarion Common Stock for a
longer period in order to take advantage of the tax-deferred nature of the
transaction, the dividend history of the Aquarion Common Stock and the fact that
the NCC Common Stock effectively has no trading market, the Board did not
consider the four-month holding period to be a major impediment in the structure
of the Acquisition.     
    
  The NCC Board made its determination without the assistance of a financial
advisor and without a "fairness opinion." NCC is in the regulated business of
public water supply within the State of Connecticut and is experienced in
regulation by the DPUC, which determines the rates water companies may charge
for water service and which must approve the economic aspects of the
transaction. The NCC Board believed that it could rely on the regulatory and
financial experience     

                                       32
<PAGE>
 
    
of its management in evaluating the transaction, without
incurring the expense of a fairness opinion, in addition to the fact that NCC
solicited and considered other proposals relating to the sale of its
subsidiaries.     

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 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 
concerning the business of public water supply in Connecticut (and in
particular the business of NCC), and utility regulation and ratemaking in
Connecticut, in considering the financial viability of the Acquisition. The
relatively small size of the transaction was also a factor in not retaining an
outside financial advisor. 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 and its amendments are annexed as 
Exhibits A, B, C and D to this Prospectus/Proxy Statement and are
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 

                                       33
<PAGE>
 
    
of NCCs obligation to repay borrowings from Charles Perkins in an amount not to
exceed $130,000 plus (b) an amount not less than $2,600,000 which represents the
amount of $3,500,000, reduced by certain indebtedness of NCC and its
subsidiaries and certain transaction costs (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, and (iv) for the deposit of 10% of the
shares of Aquarion Common Stock issued and delivered in payment of the Purchase
Price into the Escrow Fund (more fully 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. 2.8% of the outstanding Common
Stock of RWSC is not owned by NCC and is not being purchased as part of the
Acquisition. The Purchase Price may be greater than the minimum amount stated
above to the extent that NCC or its subsidiaries pay certain of their respective
indebtedness before the Acquisition Closing. However, it is not anticipated that
such repayments will aggregate more than approximately $60,000 in amount.     
    
 The $900,000 reduction in the original amount of $3,500,000 to arrive at
the Purchase Price consists of (i) approximately $371,000 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) $130,000 of liabilities of NCC and its subsidiaries to A. Leland
Glidden, a shareholder and director of NCC, which will be assumed and paid by
BHC at the Closing; (iv) approximately $199,000, representing the
estimated amount of  water bills in arrears owed to BHC by NCWC for purchased
water and (v) approximately $95,000 representing two demand notes which the DPUC
has required to be deducted from the consideration being paid for NCC's assets.
         
  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. 
Currently, pursuant to the terms of the Acquisition Agreement, the Acquisition
Agreement  may be terminated if the Closing Date has not occurred on or
before June 30, 1995.  However, the approval currently granted by decision
of the DPUC has extended the Closing Date only to June 30, 1994. The parties
have requested the DPUC to extend the Closing Date to June 30, 1995.

                                       34

  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 transaction or time period prior to the Closing Date, 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. Nothing contained in the Acquisition
Agreement shall be deemed to constitute a waiver of any rights that an NCC
Shareholder may have against NCC, Aquarion or BHC under the Securities Act of
1933 or other applicable federal law.     
    
ACQUISITION AGREEMENT - ESCROW FUND     
    
 At the Acquisition Closing, BHC, NCC and an escrow agent to be
determined (the "Escrow Agent") will enter into an escrow agreement (the "Escrow
Agreement") for the establishment of the Escrow Fund. BHC will deposit 10% of
the shares of Aquarion Common Stock (the "Escrow Shares") to be received by NCC
in payment of the Purchase Price into the Escrow Fund. BHC will have the right
to assert claims for indemnification obligations of NCC described in the
preceding paragraph during the term of the Escrow Agreement. The Escrow
Agreement will terminate on the earlier to occur of (i) the first anniversary of
the Closing Date and (ii) the date on which the audited financial statements
of BHC for the year ended December 31, 1995 are available (the "Termination
Date"). On the Termination Date, the Escrow Agent will distribute any shares of
Aquarion Common Stock then remaining in the Escrow Fund to the holders of
Class B Common Stock (or former holders, if the Liquidation is then otherwise
completed) (the "Escrow Participants") in proportion to their respective
ownership of Class B Common Stock immediately prior to the closing of the
Acquisition. Any dividends paid on the Escrow Shares during the term of the
Escrow Agreement will be distributed to the Escrow Participants as received by
the Escrow Agent in accordance with their respective ownership of shares of
Class B Common Stock.    
    
 Such dividends will not be made part of the Escrow Fund and will not be
available for the payment of indemnification obligations under the Acquisition
Agreement. The holders of the Class B Common Stock will be the beneficial
owners of the Escrow Fund, and will have proportionate voting power with respect
to the Escrow Shares during the term of the Escrow Agreement.     
    
  The expenses of the maintenance of the Escrow Fund, including the fees and
expenses of the Escrow Agent, shall be paid by Aquarion. NCC and BHC will pay
any additional expenses incurred by either of them in connection with the Escrow
Fund, including, but not limited to, the costs related to the dispute of
indemnification claims made against the Escrow Fund.     

                                       35
<PAGE>
 
    
  As stated above, in the Acquisition Agreement NCC agreed, for itself and its
shareholders, to indemnify BHC for losses incurred in connection with any breach
of representations and warranties by NCC. After the termination of the Escrow
Fund and the consummation of the Liquidation of NCC, BHC will be required to sue
the individual NCC Shareholders for any such claims. NCC does not currently
believe that there will be any material breaches of representations or
warranties under the Acquisition Agreement at the Acquisition Closing which will
give rise to indemnification obligations of NCC under the Acquisition Agreement.
If indemnification claims are asserted in amounts that exceed the amount of the
Escrow Fund, BHC will have to seek to recover such claims from the NCC
Shareholders.     

CONDITIONS TO CLOSING ON THE ACQUISITION AGREEMENT TRANSACTIONS
    
  In addition to approval of the Acquisition, the Amendment and the  Plan of
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  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 Acquisition Agreement and
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
    
 Currently, pursuant to the terms of the Acquisition Agreement, the
Acquisition Agreement may be terminated  if the Closing Date has not occurred
on or before June 30, 1995.  However, the approval currently granted by decision
of the DPUC has extended the Closing Date only to June 30, 1994. The parties
have requested the DPUC to extend the Closing Date to June 30, 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  Amendments thereto are
annexed as Exhibits  E, F and G to this Prospectus/Proxy Statement and 
are 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  exchange of properties
contemplated thereby.     
    
  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
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  $305,000 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
 $305,000 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 Agreements 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      

                                       36
<PAGE>
 
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 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 

                                       37
<PAGE>
 
    
of river channel improvements, will not exceed $200,000. The conditions
described in (v), (vii), (xi), (xii) and (xiii) have been satisfied or waived,
and it is anticipated that the conditions set forth in (vi), (viii) and (x) will
be satisfied or waived, on or before the Closing Date. The condition set forth
in (ix) is dependent upon the DPUC's decision in the reopened acquisition
approval proceeding, which decision is expected to be issued on approximately
April 19, 1995.     

TERMINATION OR AMENDMENT OF THE PROPERTY EXCHANGE AGREEMENT
    
  The Property Exchange Agreement may be terminated  in the event that (i)
the Acquisition Agreement is terminated, (ii) the Acquisition Closing does
not occur, (iii) the Property Exchange Closing does not occur on or before 
June 30, 1995 or (iv) by mutual written consent of MELP, STD, NCWC and
Aquarion. However, the approval currently granted by decision of the DPUC has
extended the Closing Date only to June 30, 1994. The parties have requested the
DPUC to extend the Closing Date to June 30, 1995. 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  and Property Exchange, the Acquisition Closing and the
Property Exchange Closing are 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.
In approximately November, 1992 STD filed an application with the DEP for
approval of a diversion permit relating to the  use of water from the
Reservoir in STD's water supply system. STD, NCWC and BHC also applied to the
DPHAS to formally approve the transfer of such  Reservoir from NCWC to STD.     
    
  After several hearings and the submission of requested  documents, the DPUC
 on June 30, 1993  issued its  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
amounts owed to suppliers, shareholders or lending institutions prior to the
Acquisition Closing. If NCC is unable to do so, BHC is to pay the amounts owed
at Acquisition Closing and reduce the Purchase Price by a corresponding amount.
These amounts have been included in the $900,000 deduction in arriving at the
Purchase Price.    
    
  The DPUC subsequently reopened its approval proceeding  in order to
address, among other matters, 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 that
abuts the Reservoir (the "Land Sale") and NCWC's request for clarification of
the responsibility of NCC to repay said loan in light of the Acquisition
Agreement. No final decision has yet been issued in the reopened proceeding and
the Acquisition can not take place until such a decision is issued. Such a
decision is currently expected to be rendered on April 19, 1995. The parties
anticipate that the Land Sale will not be consummated prior to the Closing of
the Acquisition. BHC and NCC have agreed that the Acquisition will close whether
or not the Land Sale and the retirement of NCWC debt take place prior to the
Closing. However, the effect on the Acquisition of any other terms and
provisions of the DPUC's decision, not contemplated by the agreement between BHC
and NCC, such as a ruling that NCC make provision for the repayment of the loan
or reduce the Purchase Price in the amount of the shortfall, cannot be
predicted.    
                                       38
<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, after the proposed Reservoir transfer takes place, of
watershed and non-watershed land. In the event that DPHAS does not issue the
permit, STD would not be able to purchase the Reservoir and it is unlikely that
the Acquisition would occur. A diversion permit from the DEP is required in
order for STD to use water from the 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 the petitioners have filed an
appeal from the DEP ruling in Connecticut State Superior Court. 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 unless the matter is returned to
DEP jurisdiction prior to the Property Exchange Closing. See "Proposed
Acquisition--Regulatory Approvals."      
 
RESALE OF AQUARION COMMON STOCK
   

  The shares of Aquarion Common 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. NCC Shareholders who
are affiliates of NCC at the time of the Special Meeting will be able to resell
shares of Aquarion Common Stock in compliance with the volume and manner of
sale restrictions of Rule 144 under the Securities Act. This Joint Proxy
Statement/Prospectus does not cover resales of Aquarion Common Stock received by
any person, other than NCC or the Escrow Agent, 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. NCC has no current intention of
disposing of shares of Aquarion Common Stock other than pursuant to the Plan of
Liquidation in order to pay creditors, if any, and Dissenting Shareholders, if
any.  Aquarion has agreed to permit the Escrow Agent and NCC to sell shares of
Aquarion Common Stock during the initial four-month period following the Closing
Date to satisfy, in the case of the Escrow Agent, indemnification claims which
BHC or its affiliates might have for certain liabilities resulting from the
Acquisition, and, in the case of NCC, expenses of the Liquidation, claims of
creditors or payments to Dissenting Shareholders.      
 
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 amount to be paid for the
Acquisition from $3.25 million to $3.5 million (plus in each case the assumption
of a specified debt) 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 Closing or on June 30, 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 the 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      

                                       39
<PAGE>
 
    
Connecticut Department of Environmental Protection is subject to renewal in
1995. As of December 31, 1994, NCWC owed BHC $199,000 for payments under this
contract. It is estimated that the amount owed by NCWC at the Closing will equal
approximately $199,000 and will reduce the Purchase Price to that extent. This
amount has been reflected in arriving at the Purchase Price.     

                           
                           PLAN OF LIQUIDATION 


PROVISIONS OF PLAN OF LIQUIDATION
   
  A copy of the Plan of Liquidation is annexed as Exhibit H 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 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 with certainty at this time. Although
the Certificate of Incorporation of NCC provides that, on liquidation, the
holders of NCC Class A Common Stock will receive $35.00 per share plus accrued
but unpaid dividends to the date of the liquidation distribution, 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 and that the value of the Aquarion Common Stock for purposes of
calculating the distribution payable to holders of Class A Common Stock in the
Liquidation will be the value as calculated over the Pricing Period pursuant to
the Acquisition Agreement.     

    
  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 equal to $35.00 plus all accrued but unpaid
dividends on the Class A Common Stock to the date of the liquidating
distribution. It is the current intention of the Board of Directors of NCC to
declare a dividend equal to $0.25 on each share of Class A Common Stock on March
31, 1995 and to continue to do so on a quarterly basis until such shares are no
longer outstanding pursuant to the Plan of Liquidation in order to maintain
dividend arrearages of less than $2.00 per share of Class A Common Stock.
Therefore, NCC has estimated the per share distribution to be made to holders of
Class A Common Stock in the Liquidation to consist of a number of shares of
Aquarion Common Stock with a value as calculated over the Pricing Period
pursuant to the terms of the Acquisition Agreement, equal to $37.00 per share.
     
    
  All of the directors and officers of NCC who are also shareholders of NCC have
indicated that they intend to vote for the Plan of Liquidation in their capacity
as shareholders. In order to effectuate the Plan of Liquidation, NCC will give
notice to all known creditors and will pay or make adequate provision for any
liabilities for which a creditor makes a claim. Under Connecticut law, in order
to bar any potential creditors' claims, at least four months must elapse between
the commencement of the liquidation of NCC and the distribution of Aquarion
Common Stock to holders of Class A Common Stock and Class B Common Stock. To the
extent that shares of Aquarion Common Stock must be used to pay claims of
creditors, the number of shares of Aquarion Common Stock distributable to
holders of Class B Common Stock will be reduced. In addition, payments, if
any, to Dissenting Shareholders will be paid by liquidating Aquarion shares
received as Purchase Price and, to the extent that the payment to Dissenting
Shareholders exceeds on a per share basis the value of the shares of Aquarion
Common Stock receivable per share of Class B Common Stock held by non-dissenting
shareholders, the effect will be to reduce the number of shares of Aquarion
Common Stock received by holders of Class B Common Stock.      
    
  NCC estimates that the expenses of the Liquidation will be approximately
$20,000, consisting of filing fees, the costs of notifying creditors, preparing
final tax returns and fees of professionals. NCC will also have available to it,
for the payment of such expenses, dividends which may be received on the
Aquarion Common Stock from the Closing Date to the date of the liquidating
distribution. The costs of liquidation to the extent they exceed available
dividends will be paid by liquidating shares of Aquarion Common Stock received
as Purchase Price and will reduce the number of shares of Aquarion Common Stock
received by holders of Class B Common Stock.

FRACTIONAL SHARES
   

  If any of the foregoing distributions 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 or, if available, from cash held by NCC
to pay liquidation expenses. 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 NCC Shareholders in an initial liquidating distribution.
Although this initial liquidating 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 liquidating distribution
will occur on or about four months following the Acquisition Closing and
dissolution of NCC. Any remaining assets of NCC will be distributed as soon as
practicable after the initial liquidating distribution.      
    
  As described above at "Proposed Acquisition - Acquisition Agreement - Escrow 
Fund," 10% of the shares of Aquarion Common Stock received by NCC at the
Acquisition Closing as the Purchase Price will be deposited in the Escrow Fund
for the satisfaction of certain NCC indemnification obligations. On the
Termination Date of the Escrow Fund, any shares of Aquarion Common Stock
remaining in the Escrow Fund will be distributed to the former holders of 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 the liquidating distribution. 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 such stock and not cash in the liquidation. The amendment is meant
to make clear that such a distribution is permitted under NCC's charter and that
the number of shares of Aquarion Common Stock distributable to holders of Class
A Common Stock in respect of their liquidation preference will be calculated
using the value of the Aquarion Common Stock as calculated over the Pricing
Period pursuant to the Acquisition Agreement.      
    
  The text of the Amendment is attached hereto as Exhibit I, 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.      


                 
                CERTAIN 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 Agreement,
Property Exchange Agreement and Plan of Liquidation.      
    
  It is a condition to the performance by NCC of its obligations under the
Acquisition Agreement that NCC have 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     
                                       41
<PAGE>
 
    
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 other than as contemplated by the Property Exchange Agreement
and the Land Sale; 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 such stock in NCC's hands immediately prior to the consummation of the
transaction; and the holding period of those 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
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

                                       42
<PAGE>
 
    
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 $305,000 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.
    
 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 who object to the Acquisition or the Plan Liquidation
("Dissenting Shareholders") 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.      
    
  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 J 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 and the Plan of Liquidation; (2) not vote any of
their shares of NCC Common Stock in favor of the Acquisition or the Plan of
Liquidation; (3) deliver to NCC, within ten (10) days after the vote on the
Acquisition and the Plan of Liquidation, 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 an NCC Shareholder's
rights under the Dissenters' Rights Statute.      
    
   The written objection must be in addition to and separate from any proxy or
vote against the Acquisition and the Plan of Liquidation. ANY SHAREHOLDER WHO
ELECTS TO EXERCISE DISSENTERS' RIGHTS MUST NOT VOTE IN FAVOR OF THE ACQUISITION
OR, IN THE CASE OF HOLDERS OF CLASS B COMMON STOCK, THE PLAN OF LIQUIDATION.
Because a proxy card left blank will, unless revoked, be voted FOR the
Acquisition and the Plan of Liquidation, in order to be assured that such
shareholder's NCC Common Stock is not voted in favor of the Acquisition and, in
the case of holders of Class B Common Stock, the Plan of Liquidation, a
shareholder electing to exercise dissenters' rights who votes by proxy must not
leave the proxy card blank but must (i) vote AGAINST the Acquisition and, in the
case of holders of Class B Common Stock, the Plan of Liquidation (ii) ABSTAIN
from voting for or against the Acquisition and, in the case of holders of Class
B Common Stock, the Plan of Liquidation. Neither a vote against the Acquisition
or the Plan of Liquidation nor a proxy card directing such vote nor an
abstention will satisfy the requirement that a written objection to the
Acquisition or the Plan of Liquidation be delivered to NCC before the vote upon
the Acquisition and the Plan of Liquidation.      

  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

                                       43
<PAGE>
 
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 Acquisition.      

  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 requirements of the Dissenters'
Rights Statute 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 NCC 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 transactions; (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.      
    
  NCC 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.      

                              
                          CONFLICTS OF INTEREST      

  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, 1990, the NCC Board adopted a resolution awarding Mr. Negria the
amount of $50,000 which represents 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. BHC has agreed to pay the amount owed to Mr.
Negria within 30 days of the Closing Date and that such amount will not be
deducted in determining the Purchase Price.      

                                       44
<PAGE>
 
    
  As of December 31, 1994, NCC and its subsidiaries owed an aggregate amount
of $130,000 to Mr. A. Leland 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,
pursuant to promissory notes payable either on demand or on or before June 30,
1995. The indebtedness described in this paragraph will be paid by BHC at the
Closing and will reduce the amount of $3,500,000 in calculating the Purchase
Price. "See Proposed Acquisition--Acquisition Agreement--Principal Provisions."
        
  Mr. McLinden and Mr. Glidden have certain interests in the transactions other
than their interests as directors or officers. Specifically, Mr. McLinden is
entitled to receive a payment that is contingent on the closing of the
Acquisition. It should be noted that the Board did not award this amount to Mr.
McLinden until after the Acquisition Agreement was approved by the Board of
Directors and executed by NCC. Neither the Board nor Mr. McLinden believes that
this potential conflict affects his view of the transactions or his
recommendation. Because this potential conflict did not arise until March 1993,
Mr. McLinden did not abstain from the initial vote of the directors approving
the Acquisition Agreement, although he did abstain from the vote taken at the
meeting of the Board on January 28, 1995 at which the Board ratified its
approval of the transactions described in this Proxy Statement.      
    
  Mr. Glidden participated in the initial vote of the directors approving of the
Acquisition. Mr. Glidden does not believe the repayment of the notes creates a
conflict of interest in the transaction because such notes are payable either on
demand or on a short term basis. Mr. Glidden does recognize that the likelihood
of repayment is enhanced by the consummation of the Acquisition, but as the
majority shareholder of NCC, Mr. Glidden believes his interests in the
transactions are in accord with those of the remaining shareholders of NCC. The
negotiation of the transaction as a tax free reorganization and liquidation of
NCC, and the receipt of Aquarion Shares as consideration for the sale of the
assets of NCC, will benefit Mr. Glidden as well as the other shareholders of NCC
whose tax basis in their shares of NCC is low.      

                 INFORMATION CONCERNING AQUARION COMPANY 

  Aquarion is a holding company whose subsidiaries are engaged both in the
regulated utility business of public water supply and in various nonutility

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 water 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 New Canaan Reservoir to meet      

                                       47

newly enacted water quality legislation. The company purchases the water from
the Regional 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 "Class III" land and a 50 foot wide strip of its Class II land
(the "Class II Strip") (collectively, the "Property"). No part of this Class III
land has frontage on or access to a public highway, and this land abuts the
Class I and Class II land of NCWC that comprises the Reservoir. The
terms and conditions of the sale and purchase were set forth in a proposed
contract of sale dated as of March 24, 1994, as amended. 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 "Access Parcel") which
would provide the NCWC Class III land with access to Michigan Road by linking
the Access Parcel to the Class II Strip. The purchasers and the owners of the
Access Parcel have entered into a contract for the sale of the Access Parcel to
the purchasers.     
    
      The sale of the Class II Strip requires approval of the DPHAS. NCWC
has filed an application with DPHAS for such approval.      
    
  NCWC intends to use the proceeds from the sale of the Property to pay the
principal of the $1,250,000 loan from the Village Bank. The loan is
secured by the Reservoir and Class III land, 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 the loan 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.
    
  RWSC'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.

<PAGE>
 
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 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 

                                       49
<PAGE>
 
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, 1996 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 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.

                                       50
<PAGE>
 
  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.      

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

  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
NLC's dividend policy is below average for that of a regulated utility and
the balance sheet of RWSC is weak. NCC has made requests to the majority and
other significant shareholders of NCC to make additional capital contributions
over the years, but such shareholders have declined such requests.  The only
additional financing from shareholders has been made in the form of loans from
A. Leland Glidden and other members of his family, which financing was made in
the form of short-term loans.      
    
  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 was $128,886. Cash flow from investing
activities decreased from $669,692 for the nine month period in 1993 to $83,958
for the period in 1994. 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.     
    
  Neither RWSC or NCWC will be permitted by DPUC regulation to borrow any
additional funds on a long term basis given the companies' respective debt to
equity ratios as calculated pursuant to such regulations. Both companies are
also under orders of the DPUC to repay principal on certain outstanding debt
obligations. For these reasons, NCWC and RWSC will have to meet its liquidity
and cash needs with cash flow from operations, as it is anticipated to have
negative cash flow from investing activities and financing activities in 1995.
     
    
  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. Neither RWSC nor NCWC has available any short-term credit facilities
from which it can finance its cash flow needs.      

  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

                                       52
<PAGE>
 
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.     
 
   
  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 the Reservoir from NCWC to STD. The DPUC
issued such approvals on June 30, 1993, but subsequently reopened its approval
proceeding in order to address, among other matters, the ability of NCWC to
repay an outstanding loan of $1.25 million with the proceeds of the Land Sale
and NCWC's request for clarification of the responsibility of NCC to repay said
loan in light of the Acquisition Agreement. No final decision has yet been
issued in the reopened proceeding and the Acquisition can not take place until
such a decision is issued. Such a decision is currently expected to be rendered
on April 19, 1995. The parties anticipate that the Land Sale will not be
consummated prior to the Closing of the Acquisition. BHC and NCC have agreed
that the Acquisition will close whether or not the Land Sale and the retirement
of NCWC debt take place prior to the Closing. However, the effect on the
Acquisition of any other terms and provisions of the DPUC's decision, not
contemplated by the agreement between BHC and NCC, such as a ruling that NCC
make provision for the repayment of the loan or reduce the Purchase Price in the
amount of the shortfall, 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 Reservoir transfer takes place, of watershed and non-watershed land. In
the event that DPHAS does not issue the permit, STD would not be able to
purchase the Reservoir and it is unlikely that the Acquisition would occur. A
diversion permit from the DEP is required in order for STD to use water from the
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 the petitioners have filed an appeal from the DEP ruling in
Connecticut State Superior Court. 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 unless
the matter is returned to DEP jurisdiction prior to the Property Exchange
Closing. See "Proposed Acquisition--Regulatory Approvals."

                  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 
nonassessable. Aquarion is authorized to issue up to 16,000,000 shares of Common
Stock, no par value (stated value $1), of which 6,605,021 were outstanding
on December 31, 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 are outstanding. 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 Aquarions 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 the Series A
Junior Participating Preferred Stock ("Series A Preferred Stock"). No shares of 
this 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 DGCL 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 are 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.      
    
   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 Series A Preferred Stock would have 150 votes per share.      

                                       55
<PAGE>
 
PREEMPTIVE RIGHTS
    
  The Certificate of Incorporation of each of NCC and Aquarion 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.

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.      

                                       56
<PAGE>
 
    
  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  
    
  Aquarions 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 BY-LAWS  
    
  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.     
    
  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.      

                                       57
<PAGE>
 
 
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 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. 

  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.

                            THE NEW CANAAN COMPANY
                            ----------------------

                  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 ranging from 7 to 75 years. 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:

demand to employees and others, bearing interest of 8.0% to 10.5%. These notes

   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

claim, damage or liability of Seller results from the fact that Seller
distributed Aquarion Common Stock to a person to whom there was not sent or
given, at or prior to the stockholders' meeting, a copy of the preliminary
prospectus (or of the Prospectus as then amended or supplemented)

          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
<PAGE>
 
                                                                              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
<PAGE>
 
                                                                              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.

for NCWC and MELP to exchange the Reservoir for the Building and immediately
thereafter for STD to acquire the Reservoir from MELP.

          II.  VALUE OF PROPERTY.
               ----------------- 

          (a)  NCWC, STD and MELP agree that the Reservoir is valued at

Statistics, United States Department of Labor.

          (c)  upon the execution of this Agreement Aquarion shall pay MELP a
deposit of $72,000 which equals three percent (3%) of the Building purchase

disapproves of the transaction as a result of a failure of a condition contained
in Paragraphs VIII(f), VIII(k), VIII(l) or VIII(n) to be satisfied.

                          Plan of Complete Liquidation


      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 2, 1992 (the "Acquisition Agreement"), as amended and (iii) the
amendment of the Corporation's certificate of incorporation to provide that the
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"), after provision is made for the payment of the
Corporation's debts and other obligations as described herein, 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.
          ------ 

          10% of the Aquarion Shares paid to the Corporation as the Purchase
Price (the "Escrow Shares") will be deposited with an escrow agent to establish
an escrow (the "Escrow") pursuant to an escrow agreement substantially in the
form attached hereto (the "Escrow Agreement").  Upon termination of the Escrow,
the

Escrow Shares remaining in the Escrow shall be distributed to the holders of
Class B Common Stock, no par value ("Class B Common Stock"), of the Corporation
in accordance with the Escrow Agreement and such holders' relative holdings of
Class B Common Stock on the Closing Date (as defined in the Acquisition
Agreement).      
    
      3.  Initial Distribution.      
          -------------------- 
    
          (a) After the Escrow described in the previous paragraph has been
established, and provision has been made for the Corporation shall make an
initial distribution of Aquarion Shares (the "Initial Distribution Shares")
directly to the stockholders of the Corporation in accordance with subparagraph
(b) hereof, provided that (i) all creditors of the Corporation shall first be
paid in full for the amount of their claims, including payments to shareholders
who exercise dissenters' rights of appraisal in connection with the acquisition
(ii) possession of the Escrow Shares will remain with the escrow agent pursuant
to the terms of the Escrow Agreement, (iii) no fractional shares of Aquarion
common stock will be distributed, but, rather, cash will be distributed in an
amount equal to the value of any such fractional shares on the date of such
distribution and (iv) the value of an Aquarion Share will be calculated on or
immediately prior to the date of each distribution made pursuant to the
Liquidation.      
    
          (b)  The distribution of the Initial Distribution Shares shall be as
follows:      
<PAGE>

for each share of Class A Common Stock, Aquarion Shares with a value, determined
in accordance with the valuation of the Aquarion Common Stock as provided in the
Acquisition Agreement, equal to $35.00 plus all accrued but unpaid dividends to
the date of such liquidating distribution.  Holders of Class A Common Stock
shall not be entitled to any further distribution with respect to such shares.
         
          (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.
         
      4.  Final Distribution.      
          ------------------ 
    
          To the extent that the Corporation has any cash or other assets on the
date that it is entitled to make a final distribution of assets, such assets
will be distributed pro-rata to the holders of the Class B Common Stock in
accordance with their respective holdings of such shares on the Closing Date,
provided that holders of Class A Common Stock have received full payment in
respect of their shares of Class A Common Stock.      

          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

upon receipt of the final distribution herein authorized.
    
      5.  Dissolution and Complete Liquidation.

          The officers and the Board of Directors of the Corporation shall
proceed with the voluntary dissolution and complete liquidation of the
Corporation under the laws of the State of Connecticut as promptly as
practicable, but in any event within twelve months from the date of adoption of
this plan.
    
      6.  Authorization to Execute and File Documents.

          The officers of the Corporation are authorized, empowered and directed
to execute and file all documents which they deem necessary or advisable to

                                                                  EXHIBIT J     

                   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.

                    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.

Aquarion Company
835 Main Street
Bridgeport, Connecticut  06601-2353


Ladies and Gentlemen:


        We have acted as your counsel with respect to the registration statement
on Form S-4 (the "Registration Statement") (File No. 33-57013) under the
Securities Act of 1933, as amended (the "Act"), as filed by Aquarion Company
("Aquarion" or the "Company") with the Securities and Exchange Commission (the
"Commission") relating to the issuance of up to 140,000 shares of the Company's
Common Stock, without par value (the "Common Stock"), in connection with the
proposed acquisition (the "Acquisition") by Bridgeport Hydraulic Company
("BHC"), a subsidiary of the Company, of all of the assets of The New Canaan
Company ("NCC"), pursuant to an Acquisition Agreement, dated as of September 2,
1992, by and among NCC, Aquarion and BHC as thereafter amended from time to
time.

        We have examined the Registration Statement and the related
Prospectus/Proxy Statement (the "Prospectus").  We have also examined documents
and records, and have made such examination of law as we deemed relevant and
necessary in order to give this opinion.  In our examination, we have assumed
the genuineness of all signatures, the legal capacity of natural persons, the
authenticity of the documents submitted to us as originals, the conformity to
original documents of all documents submitted to us as certified or photostatic
copies and the authenticity of the originals of such latter documents.  As to
any facts material to this opinion which we did not independently establish or
verify, we have relied upon statements and representations of officers and other
representatives of Aquarion and BHC.  We

Aquarion Company                      -2-                       January 27, 1995



have assumed without verification the accuracy of the representations as to
factual matters set forth in the Prospectus.

        The opinions set forth herein are based upon the federal laws of the
United States and the laws of the States of Connecticut and of Delaware, and no
opinion is expressed as to the laws of any other jurisdiction.

        Based upon and subject to the foregoing, we are of the opinion that:

        1.   The Company is a corporation duly organized, validly existing and
             in good standing under the laws of the State of Delaware, has
             16,000,000 shares of authorized Common Stock and has the power and
             authority to issue up to said 140,000 shares of Common Stock.

        2.   Said up to 140,000 shares of Common Stock have been duly authorized
             and at such time as certificates representing said up to 140,000
             shares of Common Stock have been duly delivered and paid for in
             accordance with the terms and conditions described in the
             Registration Statement, said up to 140,000 shares of Common Stock
             will be validly issued, fully paid and nonassessable shares of
             Common Stock.

        We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to any references to us in the Registration
Statement.

                                       Very truly yours,

                                       DAY, BERRY & HOWARD

                       CONSENT OF INDEPENDENT ACCOUNTANTS
