                          WESTFIELD, NEW JERSEY 07090

                   PROPOSED MERGER -- YOUR VOTE IS IMPORTANT

Dear E'town Corporation Shareholder:

     We invite you to attend a Special Meeting of Shareholders of E'town
Corporation, which will be held at The Westwood, 438 North Avenue, Garwood, New
Jersey, on Thursday, May 18, 2000 at 10:00 a.m.

     At this important meeting, we will ask you to approve an Agreement and Plan
of Merger (the "Merger Agreement") among E'town Corporation ("E'town"), Thames
Water Plc ("Thames") and Edward Acquisition Corp., a wholly-owned subsidiary of
Thames ("Merger Sub"). Merger Sub was created by Thames specially for this
transaction. Under the Merger Agreement, Merger Sub will merge with and into
E'town. In effect, E'town will become a wholly-owned subsidiary of Thames.

     If the merger is completed, each share of E'town common stock you own will
entitle you to receive $68.00 in cash.

     YOUR VOTE IS VERY IMPORTANT.  In order to complete the merger we need both
participation by shareholders sufficient to secure a quorum and the affirmative
vote of a majority of the votes cast by the holders of the shares of E'town
common stock entitled to vote on the Merger Agreement. Failure to secure a
quorum on the date set for the Special Meeting would require an adjournment that
would cause us to incur considerable additional expense. Only shareholders of
record of E'town on March 30, 2000 are entitled to attend the Special Meeting
and vote.

     Even if you plan to attend the Special Meeting, please take the time to
vote by completing the enclosed proxy card and mailing it to us. If you sign,
date and mail your proxy card without indicating how you want to vote, your
proxy will be counted in favor of the Merger Agreement. Except for shares held
through the Elizabethtown Water Company Savings and Investment Plan - 401(k),
you may also vote by telephone by calling the toll-free number on your proxy
card and you may vote by Internet by visiting the web-site listed on your proxy
card. You have the option of revoking your proxy at any time or to vote your
shares personally, on request, if you attend the meeting.

     The accompanying proxy statement includes answers to frequently asked
questions and a summary description of the merger, followed by a more detailed
discussion of the merger and other related matters. WE ENCOURAGE YOU TO READ THE
ENTIRE PROXY STATEMENT CAREFULLY.

     THE E'TOWN BOARD OF DIRECTORS HAS DETERMINED THAT THE MERGER IS IN THE BEST
INTERESTS OF E'TOWN SHAREHOLDERS AND UNANIMOUSLY RECOMMENDS THAT YOU VOTE "FOR"
THIS TRANSACTION.

                                          Sincerely,

                                          ANNEEVANSESTABROOK SIG

COMMISSION HAS APPROVED THE MERGER, OR DETERMINED THAT THIS PROXY STATEMENT IS
ACCURATE OR COMPLETE. IT IS ILLEGAL FOR ANYONE TO TELL YOU OTHERWISE.

     Thames has furnished all the information in this proxy statement concerning
Thames, and E'town has furnished all the information concerning E'town.

                     Proxy statement dated April 14, 2000.

                           TO BE HELD ON MAY 18, 2000

                                                            Date: April 14, 2000

To the Shareholders of E'town Corporation:

     The board of directors of E'town Corporation ("E'town") is pleased to
provide you with notice of, and cordially invites you to attend in person or by
proxy, a Special Meeting of Shareholders (the "Special Meeting") which will be
held at The Westwood, 438 North Avenue, Garwood, New Jersey, on Thursday, May
18, 2000 at 10:00 a.m. for the following purposes:

          1. To consider and vote upon a proposal to approve an Agreement and
     Plan of Merger, dated as of November 21, 1999 (the "Merger Agreement"),
     attached as Appendix A to the accompanying proxy statement, providing for
     the merger of Edward Acquisition Corp. with and into E'town. Edward
     Acquisition Corp. is a wholly-owned subsidiary of Thames Water Plc
     ("Thames") that was specially organized for this transaction. As a result
     of this merger, E'town will become a wholly-owned subsidiary of Thames;

          2. To transact such other business as may properly come before the
     Special Meeting or any adjournment or postponement thereof.

     Only E'town shareholders at the close of business on March 30, 2000 will be
entitled to notice of and to vote at the Special Meeting or its postponements or
adjournments. A complete list of shareholders entitled to vote at the Special
Meeting will be available at that meeting for inspection by any shareholder.
Approval of the Merger Agreement will require the affirmative vote of a majority
of the votes cast by the holders of shares of E'town common stock entitled to
vote on the Merger Agreement.

     THE E'TOWN BOARD OF DIRECTORS HAS DETERMINED THAT THE MERGER IS IN THE BEST
INTERESTS OF E'TOWN SHAREHOLDERS AND UNANIMOUSLY RECOMMENDS THAT YOU VOTE TO
APPROVE THE MERGER AGREEMENT AT THE SPECIAL MEETING.

     Please sign, date and return the accompanying proxy card in the enclosed
addressed envelope, which requires no postage if mailed in the United States.
Except for shares held through the Elizabethtown Water Company Savings and
Investment Plan - 401(k), you may also submit your vote by telephone or via the
Internet in accordance with the instructions on the accompanying proxy card. You
may revoke your proxy at any time before the vote is taken, in accordance with
the instructions set out on pages 13 to 14 of the accompanying proxy statement.

     PLEASE DO NOT SEND STOCK CERTIFICATES WITH YOUR PROXY CARD.

     Under New Jersey law, shareholders of E'town do not have appraisal rights
in the merger. Therefore, if you vote against the merger, but the merger is
eventually approved, you will receive the per share merger consideration payable
in the merger rather than an appraised value of the shares you hold.

                                          By Order of the Board of Directors,

                                          /s/ Walter M. Braswell
                                          WALTER M. BRASWELL
                                          Secretary

                     QUESTIONS AND ANSWERS ABOUT THE MERGER

Q.  WHAT WILL HAPPEN IN THE PROPOSED TRANSACTION?

A.  Edward Acquisition Corp. ("Merger Sub"), a wholly-owned subsidiary of Thames
    Water Plc, ("Thames") formed solely to complete the merger, will merge into
    E'town Corporation ("E'town"). As a result, E'town will become an indirect
    and wholly-owned subsidiary of Thames.

Q.  WHY DID E'TOWN'S BOARD DECIDE THAT THIS MERGER IS THE BEST WAY TO MAXIMIZE
    SHAREHOLDER VALUE NOW?

A.  The board believes that the timing for a sale of E'town is optimal. Market
    to book value ratios and price to earnings ratios for many water utilities,
    including E'town, are at or near all-time highs, and water utility companies
    are being acquired for attractive prices. The $68.00 per share price to be
    paid by Thames represents a premium of approximately 36% over the $49.94 per
    share average closing price for E'town common stock for the 30 calendar days
    prior to the announcement of the merger, and a 24% premium over E'town's
    all-time-high closing share price of $54.63. The price to be paid by Thames
    exceeds the level that E'town could reasonably be expected to achieve as an
    independent company. The water industry in the United States is
    consolidating rapidly and is increasingly being dominated by large
    companies. Your board of directors determined that because of E'town's size
    and limited capital resources, it could not easily take advantage of growth
    opportunities through acquisitions and, as a result, might not remain
    competitive in the industry. In addition, your board determined that E'town
    may not be able to participate in public/private partnerships that it may
    wish to pursue in the future because of the significant amounts of capital
    required to be contributed by prospective private parties such as E'town.
    Your board determined that E'town shareholders could best benefit from the
    industry consolidation through a sale of E'town to, or a business
    combination of E'town with, a larger industry leader.

    Please read the more detailed description of E'town's reasons for the merger
    on pages 18 to 20.

Q.  WHAT EFFECT WILL THE MERGER HAVE ON E'TOWN'S CUSTOMERS AND EMPLOYEES?

A.  Your board of directors believes that the merger will position E'town as an
    integral part of one of the world's premier water services companies and
    will provide strategic growth opportunities and access to cutting-edge
    technologies that will benefit both E'town's customers and employees in a
    manner that E'town could not achieve on its own.

Q.  WHAT WILL I RECEIVE IN THE MERGER?

A.  In exchange for each share of E'town common stock you own, you will have the
    right to receive $68.00 in cash.

Q.  WILL I STILL BE A SHAREHOLDER OF E'TOWN AFTER THE MERGER?

A.  No. In the merger, you will receive cash in exchange for all of your E'town
    shares. Following the merger, E'town will be a wholly-owned subsidiary of
    Thames and its shares will be delisted from the New York Stock Exchange.

Q.  HOW WILL THE MERGER AFFECT MY FUTURE DIVIDENDS?

A.  You will continue to receive regular quarterly dividends on your E'town
    shares until the closing of the merger. If the closing of the merger does
    not occur between a record date and payment date of a regular quarterly
    dividend, E'town may declare a special prorated dividend, at the then
    quarterly rate, for the period between that payment date and the closing of
    the merger. After the closing of the merger, you will not own any E'town
    shares on which to receive dividends.

Q.  WHAT ARE THE FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER TO SHAREHOLDERS?

A.  You will be taxed on your receipt of the cash given to you for your shares
    of E'town common stock to the extent that the amount of cash you receive
    exceeds your tax basis in those shares. Please read the more detailed
    description of Federal income tax consequences on page 32.

    THE TAX CONSEQUENCES OF THE MERGER TO YOU WILL DEPEND ON YOUR OWN SITUATION.
    YOU SHOULD CONSULT YOUR TAX ADVISORS FOR A FULL UNDER-

    STANDING OF THE TAX CONSEQUENCES OF THE MERGER TO YOU.

Q.  WHAT DO I NEED TO DO NOW?

A.  Please read this document carefully, and then complete, sign, date and mail
    your proxy card in the enclosed return envelope as soon as possible. That
    way, your E'town shares can be represented at the Special Meeting of
    Shareholders. Except for shares owned through the Elizabethtown Water
    Company Savings and Investment Plan -- 401(k) ("401(k) Shares"), you may
    also vote by telephone or via the Internet by calling the toll-free number
    or visiting the web-site listed on your proxy card. If you intend to vote by
    telephone or via the Internet, do not return the proxy card.

    If you own 401(k) Shares, you will receive a separate proxy card for those
    shares. You will not be able to vote these shares by telephone or via the
    Internet.

    If you own shares through participation in the E'town Corporation Dividend
    Reinvestment and Stock Purchase Plan, your proxy card covers both plan
    (uncertificated) shares and certificated shares unless the shares have been
    registered in different names. If you have registrations of shares in
    different names, you will receive a separate proxy card for each name under
    which you hold shares.

    If a broker holds your shares as nominee, you will receive a voter
    information form from your broker.

Q:  SHOULD I SEND IN MY STOCK CERTIFICATES NOW?

A.  No. Do not send in your stock certificates now. If the merger is completed,
    you will receive written instructions on how to exchange them.

Q.  WHO MUST APPROVE THE MERGER?

A.  - E'town's board of directors (already approved);

    - The board of directors of Thames (already approved);

    - The board of directors of Merger Sub (already approved); and

    - The majority of the votes cast by the holders of shares of E'town common
      stock entitled to vote on the Merger Agreement.

    We must also obtain some regulatory approvals for the merger. Please read
    the more detailed description of the regulatory approvals on pages 28 to 29.

    E'town and Thames cannot complete the merger without the approval of the
    majority of the votes cast by the holders of shares of E'town common stock
    entitled to vote on the Merger Agreement. Your vote is very important.

    THE E'TOWN BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS VOTING "FOR" APPROVAL
    OF THE MERGER AGREEMENT.

Q.  DO THE SHAREHOLDERS OF THAMES VOTE ON THE MERGER?

A.  No. Only E'town shareholders vote on the merger.

Q.  WHEN DOES E'TOWN EXPECT TO COMPLETE THE MERGER?

A.  We are working to complete all aspects of the merger as quickly as possible.
    Currently, we expect to complete the merger prior to the end of 2000.

Q.  WHAT HAPPENS IF I DO NOT INSTRUCT A BROKER HANDLING MY SHARES ON HOW TO VOTE
    ON THE MERGER?

A.  If a broker holds your E'town shares as nominee, he or she will not be able
    to vote them without instructions from you. You will receive a voter
    information form from your broker. If you do not instruct your broker on how
    to vote, you will not be voting and this will hinder the securing of a
    quorum for the Special Meeting.

Q.  WHAT HAPPENS IF I DO NOT RETURN MY PROXY?

A.  If you do not return your proxy, or do not vote by telephone or via the
    Internet, you will not be counted as a voting shareholder unless you attend
    the Special Meeting and vote. And, unless you attend the Special Meeting,
    this will hinder the securing of a quorum for that meeting. Failure to
    secure a quorum for the Special Meeting will lead to the need for an
    adjournment that would cause E'town to incur considerable additional
    expense.

    If you hold E'town shares through a stock plan such as the E'town Dividend
    Reinvestment and Stock Purchase Plan, or the Elizabethtown

    Water Company Savings and Investment Plan -- 401(k), you are allowed to vote
    the E'town shares allocated to your account to approve or disapprove the
    Merger Agreement.

    If you do not return a proxy card for your shares held through the Dividend
    Reinvestment and Stock Purchase Plan, those shares will not be voted unless
    you (or your appointed representative) vote in person at the Special
    Meeting. If you sign and return a proxy card for these shares, but do not
    provide instructions on how to vote them, these shares will be voted "FOR"
    the Merger Agreement.

    For your 401(k) Shares, if you fail to submit a proxy card, or you fail to
    provide voting instructions on your returned proxy card, the trustees of the
    401(k) Plan will direct the voting of your 401(k) Shares for you.

    Please read the more detailed description of the consequences of not voting
    these shares on page 13.

Q.  CAN I CHANGE MY VOTE AFTER I HAVE MAILED IN MY SIGNED AND DATED PROXY CARD?

A.  Yes. You may revoke your proxy at any time before your shares are voted.
    Please refer to the instructions on how to revoke your proxy set out on
    pages 13 to 14.

Q.  DO I HAVE APPRAISAL RIGHTS FOR MY SHARES IF THE MERGER IS COMPLETED?

A.  No. An appraisal right permits shareholders to receive payment for their
    shares in an amount determined by an independent appraisal rather than the
    consideration which they otherwise would receive in the transaction. Under
    New Jersey state law, E'town shareholders do not have appraisal rights in
    the merger. Therefore, if you vote against the merger but the merger is
    nonetheless approved by the requisite votes of the shareholders, you will
    still receive the $68.00 per share cash consideration rather than an
    appraised value of the shares you hold.

Q.  WHAT REGULATORY APPROVALS ARE NEEDED FOR THE MERGER?

A.  The merger must be approved by the New Jersey Board of Public Utilities and
    by the U.S. federal antitrust authorities. Certain clearances must also be
    obtained from New Jersey environmental regulators.

Q.  ON WHAT OTHER MATTERS WILL I VOTE AT THE SPECIAL MEETING?

A.  It is unlikely that you will be asked to vote on any other matters at the
    Special Meeting, except possibly procedural items relating to the conduct of
    the Special Meeting.

Q.  WHO CAN ADDRESS ANY ADDITIONAL QUESTIONS I HAVE?

A.  Donna Gregory, Director of Investor Relations of E'town Corporation, 600
    South Avenue, Westfield, New Jersey 07090.

                              CAUTIONARY STATEMENT
                      REGARDING FORWARD-LOOKING STATEMENTS

     E'town has made forward-looking statements in this document (and in
documents incorporated by reference) that are subject to risks and
uncertainties. These statements include information concerning possible or
assumed future financial condition, results of operations and businesses of
E'town. You can find many of these statements by looking for words such as
"believes," "expects," "anticipates," "estimates" or similar expressions.

     These forward-looking statements are subject to numerous assumptions, risks
and uncertainties. The following are some of the factors that may cause actual
results to differ from the results indicated in the forward-looking statements:

  - regulatory issues, including the outcome of rate cases;

  - changes in weather patterns;

  - the ability to capitalize on growth opportunities for the companies'
    regulated and unregulated businesses;

  - the impact of competition from other water services companies;

  - variations in the prices of materials used in the water services industry;

  - exposure to environmental issues and liabilities;

  - the risk that government authorities may impose unfavorable terms as a
    condition of the merger;

  - the risk of favorable customer contracts expiring or being renewed on less
    attractive terms;

  - the risks associated with the pursuit of new markets; and

  - other considerations that may be disclosed at various times in publicly
    issued documents or filings of E'town.

     The areas of risk described above should be considered in connection with
any written or oral forward-looking statements that may be made after the date
of this proxy statement by E'town or anyone acting on its behalf. Except for its
ongoing obligations to disclose material information under the federal
securities laws, E'town undertakes no obligation to release publicly any
revisions to any forward-looking statements to report events or circumstances
after the date of this proxy statement or the occurrence of unanticipated
events.

EDWARD ACQUISITION CORP. (PAGE 10)

     Edward Acquisition Corp., a New Jersey corporation ("Merger Sub"), is an
indirect, wholly-owned, special-purpose subsidiary of Thames. Merger Sub was

E'TOWN CORPORATION (PAGE 10)
600 South Avenue
Westfield, New Jersey 07090
(908) 654-1234

     E'town Corporation ("E'town") is a holding company primarily engaged in
water-related businesses. E'town provides water and wastewater services through
its regulated utilities and nonregulated contract operations. It is the parent
company of Elizabethtown Water Company ("Elizabethtown"), which, with its
subsidiary, The Mount Holly Water Company ("Mount Holly"), is the fifth-largest
investor-owned water utility in the United States based on revenues.
Elizabethtown and Mount Holly provide water service to half a million people in
54 municipalities in eight central New Jersey counties, and, on a wholesale
basis, a portion of the water requirements of seven municipal systems and three
investor-owned companies serving an additional half million people. E'town's
principal contract operations subsidiaries are Edison Water Company and Liberty
Water Company. E'town is also the parent company of Applied Water Management,
Inc. ("AWM") and Applied Wastewater Management, Inc. ("AWWM") which design,
build, own and operate water and wastewater treatment facilities. E'town's
non-regulated real estate subsidiary, E'town Properties, Inc., is in the process
of selling its undeveloped real estate properties, the proceeds from which are
then reinvested in water and wastewater projects.

THE SPECIAL MEETING
(PAGES 12 TO 14)

     The Special Meeting of E'town shareholders will be held at The Westwood,
438 North Avenue, Garwood, New Jersey, on Thursday, May 18, 2000, at 10:00 a.m.

For the merger to proceed, we must obtain the affirmative vote of a majority of

vote on the Merger Agreement.

     Only the E'town shareholders at the close of business on the record date,
March 30, 2000, will be entitled to notice of the Special Meeting and only these
shareholders may vote.

     Each share of E'town common stock carries one vote. On March 30, 2000,
8,774,898 votes were eligible to be cast at the Special Meeting.

THE MERGER
(PAGES 15 TO 33)

     Under the Merger Agreement, Merger Sub will merge with and into E'town and
E'town will continue as the surviving company. In the merger, each share of
E'town common stock will be converted into the right to receive $68.00 in cash
(sometimes referred to in this document as the "merger consideration"). The
effect of the merger is that E'town will become an indirect, wholly-owned
subsidiary of Thames.

     The Merger Agreement is attached as Appendix A to this document. We
encourage you to read it carefully. It is the legal document that governs the
merger.

SURRENDER OF CERTIFICATES AND PAYMENT FOR SHARES
(PAGES 34 TO 35)

     After the merger, you will no longer have your usual rights as an E'town
shareholder. Your sole right in any E'town shares you held immediately before
the merger will be to receive the merger consideration of $68.00 per share. We
will send you letters of transmittal for use in surrendering stock certificates
and obtaining payment for surrendered shares promptly after the merger is
completed. Do not surrender any certificates until the letter of transmittal and
instructions are received.

REASONS FOR AND BACKGROUND TO THE MERGER
(PAGES 15 TO 20)

     You should review the factors that the E'town board of directors considered
when deciding whether to approve the merger.

RECOMMENDATION TO SHAREHOLDERS
(PAGE 18)

     The E'town board of directors has determined that the merger is in the best
interests of the E'town shareholders and unanimously recommends that you vote to
approve the Merger Agreement at the Special Meeting.

OPINION OF E'TOWN'S FINANCIAL ADVISOR
(PAGES 22 TO 27)

     In connection with the merger, the E'town board received a written opinion
from Salomon Smith Barney Inc. ("Salomon Smith Barney") as to the fairness, from
a financial point of view, of the merger consideration to the holders of E'town
common stock. The full text of Salomon Smith Barney's written opinion dated
November 21, 1999 is attached to the back of this document as Appendix B. We
encourage you to read this opinion carefully in its entirety for a description
of the assumptions made, matters considered and limitations on the review
undertaken.

     SALOMON SMITH BARNEY'S OPINION IS DIRECTED TO THE E'TOWN BOARD OF DIRECTORS
AND DOES NOT CONSTITUTE A RECOMMENDATION TO ANY SHAREHOLDER WITH RESPECT TO ANY
MATTER RELATING TO THE MERGER.

CONDITIONS TO THE MERGER
(PAGES 43 TO 44)

     We will complete the merger only if we satisfy several conditions,
including the following:

  - the E'town shareholders approve the Merger Agreement;

  - no legal restraints or prohibitions exist that prevent the consummation of
    the merger; and

  - we comply with the regulatory requirements set forth below under "Regulatory
    Approvals."

REGULATORY APPROVALS
(PAGES 28 TO 29)

     To complete the merger, we must obtain approvals from various federal and
state regulatory agencies, including the New Jersey Board of Public Utilities,
and the Federal Trade Commission and the Department of Justice under the
Hart-Scott-Rodino Antitrust Improvements Act of 1976. Certain clearances must
also be obtained from the New Jersey environmental regulators.

CERTAIN COVENANTS
(PAGES 36 TO 40)

     E'town has agreed not to solicit or encourage any proposal from any person
to acquire E'town or its assets, but it may respond, subject to compliance with
certain procedures, to unsolicited proposals that it may receive.

TERMINATION
(PAGES 44 TO 46)

     Under certain circumstances, the parties may terminate the Merger Agreement
prior to completing the merger. If termination occurs because E'town's board of
directors decides to pursue an alternative acquisition proposal, E'town may be
re-

                                        6
<PAGE>   13

quired to pay Thames a termination fee of $16.5 million, plus reimbursement of
expenses of up to $5 million.

MATERIAL FEDERAL INCOME TAX CONSEQUENCES
(PAGES 32 TO 33)

     Shareholders receiving cash for their shares will recognize a gain or loss
to the extent of the difference between the amount of cash they receive and
their adjusted tax basis in their E'town shares.

     THE TAX CONSEQUENCES OF THE MERGER TO YOU WILL DEPEND ON YOUR OWN
SITUATION. YOU SHOULD CONSULT YOUR TAX ADVISOR FOR A FULL UNDERSTANDING OF THE
TAX CONSEQUENCES OF THE MERGER TO YOU.

INTERESTS OF CERTAIN PERSONS IN THE MERGER
(PAGES 29 TO 32)

     When you consider the board's recommendations, you should realize that some
board members and executives will receive benefits or have interests that may be
different from yours as a shareholder. For example, Andrew M. Chapman, current
President of E'town, will be elected as a director both of the surviving company
and of Thames Water North America Inc. Mr. Chapman has also entered into a new
employment agreement with E'town which will become effective upon the completion
of the merger. Edward A. Clerico, current President of AWM and AWWM will be
elected as a director of the surviving company, and Anne Evans Estabrook will be
elected as a member of the International Supervisory Board of the international
services subsidiary of Thames.

     The members of the E'town board of directors were aware of these additional
interests and considered them when they approved the Merger Agreement.

ABSENCE OF APPRAISAL RIGHTS
(PAGE 33)

     Under New Jersey law, you do not have the right to obtain an appraised
value for your shares in place of the $68.00 per share cash payment provided in
the Merger Agreement.

E'TOWN DIVIDENDS

     The Merger Agreement does not restrict E'town's ability to declare and pay
its regular quarterly dividends prior to the completion of the merger. If the
closing of the merger has not occurred by September 30, 2000, E'town may
increase the annual rate of its regular quarterly dividends by not more than 3%.
If the merger does not become effective between a record date and payment date
of a regular quarterly dividend, E'town may declare and pay a special prorated
dividend, at the then current quarterly rate, for the period between such
payment date and the date the merger becomes effective.

                              THE SPECIAL MEETING

     The board of directors of E'town is soliciting proxies in the accompanying
form for use at the Special Meeting of E'town shareholders to be held on May 18,
2000 at 10:00 a.m. at The Westwood, 438 North Avenue, Garwood, New Jersey (and
at any adjournment or postponement of that meeting).

     The purpose of the Special Meeting is to vote upon the proposal to approve
the Merger Agreement. Under the Merger Agreement, E'town will become a
subsidiary of Thames and each E'town shareholder will receive their share of the
consideration being paid by Thames for E'town shares, i.e., $68.00 per share.

RECORD DATE; VOTING POWER; VOTE REQUIRED

     Only holders of record of E'town shares at the close of business (5:00
p.m.) on March 30, 2000 (the record date) will be entitled to notice of, and
vote at, the Special Meeting or any adjournment or postponement thereof. At the
close of business on the record date, 8,774,898 shares of E'town common stock
were issued and outstanding and entitled to vote at the Special Meeting. Each
E'town share is entitled to one vote on any matter that may properly come before
the Special Meeting. Votes may be cast at the Special Meeting in person or by
proxy. See "Voting of Proxies" below. The presence at the Special Meeting,
either in person or by proxy, of the holders of a majority of the outstanding
E'town shares entitled to vote shall constitute a quorum. If a quorum is not
present at the Special Meeting, a majority of shares that are represented, in
person or by proxy, may adjourn or postpone the meeting.

     For the Merger Agreement to be approved at the Special Meeting, the
affirmative vote of a majority of the votes cast by the holders of the shares of
E'town common stock entitled to vote on that agreement is required. Abstentions
and properly-executed broker non-votes (i.e., shares held by brokers as nominees
for shareholders who have not instructed their broker how to vote and the broker
or nominee does not have discretionary voting power on that proposal) will be
counted as present for purposes of establishing a quorum. Broker non-votes will
not be counted as affirmative votes for the purposes of determining whether the
Merger Agreement has been approved.

OWNERSHIP OF VOTING STOCK BY MANAGEMENT

     At the close of business on March 30, 2000, the record date, E'town's
directors and executive officers and their affiliates beneficially owned 576,027
shares of E'town common stock, which represents 6.56% of the shares of E'town
common stock issued and outstanding.

VOTING OF PROXIES

     Shares represented by properly signed and dated proxies received in time
for the Special Meeting will be voted in accordance with the instructions on the
proxy card. If your proxy is properly signed and dated but does not contain
voting instructions, your proxy will be voted for the approval of the Merger
Agreement. Your proxy also confers discretionary authority on the proxies to
vote on any other matter not currently known to management that may properly
come before the Special Meeting. We do not expect that any matter other than
those specifically stated in this proxy statement will be brought before the
Special Meeting.

     The persons named as proxies by an E'town shareholder may propose and vote
for one or more adjournments of the Special Meeting, including adjournments to
permit further solicitations of proxies. No proxy voted against the proposal to
approve the Merger Agreement will be voted in favor of any adjournment or
postponement.

     The grant of a proxy on the enclosed proxy card does not preclude you from
voting in person.

     If you own shares through the E'town Dividend Reinvestment and Stock
Purchase Plan but do not have certificates for them, your proxy card represents
both:

          (a) the number of shares of E'town common stock certificated in your
     name; and

          (b) the number of full shares of E'town common stock credited to your
     plan account;

                                       12
<PAGE>   19

unless the registrations are in different names. If you have shares registered
in different names, you will receive a separate proxy card for each
registration. All these shares will be voted in accordance with the instructions
on the proxy card.

     If you own shares through the E'town Dividend Reinvestment and Stock
Purchase Plan, and no instructions are indicated on a properly signed and
returned proxy card, under the terms of the plan document, all of your whole
shares held through this plan will be voted in accordance with the
recommendations of E'town's management, i.e. FOR approval of the Merger
Agreement. If, in respect of these plan shares, you do not return your proxy
card, or if you return it without signing it, none of your plan shares will be
voted unless you, or your duly appointed representative, vote in person at the
Special Meeting. If your shares are held by a broker as nominee, you will
receive a voter information form from your broker.

401(K) SHARES

     If you hold shares ("401(k) Shares") through the Elizabethtown Water
Company Savings and Investment Plan -- 401(k) (the "401(k) Plan"), you will
receive a separate proxy card for these shares. You must return this proxy card
to Corporate Election Services in order to vote your 401(k) Shares. You may not
vote 401(k) Shares by telephone or via the Internet. If you own 401(k) Shares
and either you fail to submit a proxy card or you fail to provide voting
instructions on your returned proxy card (whether signed or unsigned) for these
shares, under the terms of the 401(k) Plan document, the trustees of the 401(k)
Plan will direct the voting of all of your whole 401(k) Shares.

REVOCABILITY OF PROXIES

     If you exercise a proxy (other than in respect of 401(k) Shares or shares
held through your broker) you have the power to revoke it at any time before it
is voted:

     - by attending the Special Meeting and voting in person; or

     - by delivering a later-dated proxy to

       The Bank of New York
      E'town Corporation
      P.O. Box 11273
      New York, New York 10203-0273; or

     - by telephone, if you previously voted by telephone; or

     - via the Internet, if you previously voted via the Internet.

     Additional proxy cards (other than for 401(k) shares) are available from
The Bank of New York. Please note, however, that if you have exercised a proxy
for shares held through your broker, you can only revoke that proxy through your
broker.

     If you exercise a proxy in respect of 401(k) Shares, you have the power to
revoke it at any time before it is voted by delivering a later-dated proxy to

        Corporate Election Services
        PO Box 3230
        Pittsburgh, PA 15230-3230
        Tel. (877) 382-0000

     Additional proxy cards for 401(k) Shares are available from Corporate
Election Services.

     Merely attending the Special Meeting will not by itself revoke a proxy. If
you attend the Special Meeting you may revoke your proxy and vote in person by
informing any of the persons named on the enclosed proxy card that you wish to
revoke a previously-submitted proxy.

     We do not expect to adjourn the Special Meeting for a period long enough to
require setting a new record date for the Special Meeting. If an adjournment
occurs, it will have no effect on the ability of the E'town

                                       13
<PAGE>   20

shareholders of record as of the record date either to exercise their voting
rights or to revoke any previously-submitted proxies.

SOLICITATION OF PROXIES

     We will bear the costs of soliciting proxies from E'town shareholders and
the cost of printing and mailing this proxy statement.

     In addition to solicitation by mail, the directors, officers and employees
of E'town and its subsidiaries may solicit proxies from E'town shareholders
either by telephone or in person. These directors, officers and employees will
not receive additional compensation but may be reimbursed for out-of-pocket
expenses incurred in connection with the solicitation of proxies.

     Arrangements will also be made with banks, brokers or other custodians,
nominees and fiduciaries to forward solicitation materials to the beneficial
owners of E'town common stock held of record by these persons. E'town will
reimburse these parties for reasonable out-of-pocket expenses incurred in
forwarding the solicitation materials.

     We have retained Georgeson & Co., Inc. ("Georgeson") to help solicit
proxies. Georgeson will receive a fee that we expect will not exceed $10,000 as
compensation for its basic solicitation services, plus additional charges for
any telephone solicitation services and reimbursement of its out-of-pocket
expenses. E'town has agreed to indemnify Georgeson against certain liabilities
arising from its engagement.

     YOU SHOULD NOT SEND STOCK CERTIFICATES WITH YOUR PROXY CARDS.

     NO VOTE REQUIRED FOR THAMES SHAREHOLDERS.  The shareholders of Thames need
not approve the Merger Agreement. Thus, no one is soliciting proxies from Thames
shareholders.

                                   THE MERGER

     The discussion in this proxy statement of the merger and the principal
terms of the Merger Agreement, is qualified by reference to the Merger
Agreement, a copy of which is attached to this proxy statement as Appendix A and
is incorporated herein by reference.

GENERAL DESCRIPTION OF THE MERGER

     On November 21, 1999, E'town, Thames and Merger Sub entered into an
Agreement and Plan of Merger. This agreement is referred to in this proxy
statement as the "Merger Agreement." The Merger Agreement sets forth the terms
of a merger in which Merger Sub, a wholly-owned subsidiary of Thames, will merge
with and into E'town, with E'town as the surviving company. After the merger,
E'town will continue to conduct its businesses as an indirect, wholly-owned
subsidiary of Thames. You will cease to have any equity interest in E'town, will
not have the opportunity to participate in the earnings and growth of E'town
after the merger and will not have any right to vote on corporate matters.
Similarly, you will not face the risk of losses generated by E'town's operations
or decline in the value of E'town after the merger.

     You will receive $68.00 cash in exchange for each of your E'town shares. We
estimate that the total value of the consideration that E'town shareholders will
receive in the merger is approximately $607 million. Thames has represented in
the Merger Agreement that it will have the financial resources to complete the
merger and the arrangement of financing by Thames is not a condition to closing
the merger. Thames has advised us that it presently has sufficient cash on hand
and amounts available to it under existing credit facilities to pay the cash
consideration.

BACKGROUND TO THE MERGER

     At a meeting of E'town's board of directors held in May 1998, the board
reviewed several strategic developments that had begun to cause fundamental
changes in the U.S. water utility industry. These factors included:

     - an accelerating pace of consolidation among domestic investor-owned water
       utility companies;

     - the growth of the market for privatization contracts, whereby
       government-owned water utilities enter into long-term contracts for the
       operation and maintenance of their systems;

     - increased activity in the U.S. market by large foreign companies with
       worldwide water operations. These companies were pursuing acquisitions of
       investor-owned water companies and bidding on privatization contracts;
       and

     - increased interest by U.S. electric utility companies in the water
       sector.

     The board believed that these trends suggested that E'town needed to
explore different means to increase its size significantly so that E'town could
compete with the larger companies who were entering the U.S. market or being
formed through consolidations. These larger companies, with their greater
financial and human resources, had distinct advantages in bidding on
privatization contract opportunities, and could also attract and retain
employees who are skilled in the multiple facets of water production, delivery
and services.

     E'town's board of directors authorized management to explore opportunities
to increase E'town's size through acquiring smaller companies or merging with
companies of roughly equal size (a "merger of equals"). The board also approved
management's request to retain Salomon Smith Barney Inc. ("Salomon Smith
Barney") as a financial advisor to assist in the process, and E'town
subsequently engaged Salomon Smith Barney in July 1998.

     During the remainder of 1998 and early 1999, management made numerous
contacts with other companies in order to pursue these opportunities. During
this period, several companies expressed interest in acquiring E'town. There was
also a series of publicly-announced acquisitions of water utilities, at prices
which included attractive premiums to the book values and market prices of the
acquired companies.

                                       15
<PAGE>   22

     Given these high acquisition multiples, E'town's management concluded that
purchases of smaller companies, even if successful, would result in significant
dilution in earnings per share. The universe of similarly-sized water utilities
suitable for a merger of equals with E'town was small. Initial discussions with
a company believed by management to be the most likely candidate for a merger of
equals did not lead to serious negotiations. In light of the high prices being
paid by larger acquirors, the improved opportunities for E'town's employees
within larger companies and the competitive issues described above, in the
spring of 1999 management, with the board's approval, began to place more
emphasis on exploring a potential sale of E'town.

     In addition to the discussions referred to below, the Company had initial
meetings with two other companies and actively monitored the merger and
acquisition activity occurring in the water utility industry in order to be able
to evaluate any proposals that might be made against the increasing base of
comparable transactions data. The criteria established by the board in
evaluating a potential sale were the shareholder value offered; the commitment
of any partner to the Company's core values of environmental stewardship, high
water quality standards and strong customer service; and enhanced opportunities
for those employees who can function effectively in the increasingly competitive
environment for water companies. In 1998 and 1999, management made reports to
the board of directors of the progress of contacts and discussions with other
companies. The board authorized management to continue these activities, but
made no determination as to whether E'town should be sold.

     As part of the above-described activity, in March and May 1999, E'town
initiated discussions with two larger utility companies ("Company A" and
"Company B") and signed confidentiality and standstill agreements and exchanged
nonpublic information with both companies. These companies also conducted due
diligence investigations of E'town. Both companies also gave E'town preliminary
indications of ranges of prices they would be willing to consider to pay to
acquire E'town, assuming satisfactory completion of due diligence and
negotiation of an acceptable merger agreement. Company A indicated that it would
be prepared to offer all cash consideration or a combination of cash and stock,
subject to a "collar" mechanism to address changes in the price of its stock
prior to closing. Company B indicated that it would be prepared to offer only
its stock as consideration to E'town's shareholders, subject to a collar
mechanism.

     Company B initially suggested a purchase of E'town through a stock for
stock exchange based on 3 shares of Company B stock for 1 share of E'town stock.
For the period from June 1, 1999 through July 15, 1999, Company B's stock was
trading in the range of $22 15/16 to $24 3/8. Company B proposed that if its
stock price fell below $21 per share, Company B would have the right to deliver
the additional shares necessary to maintain the value of the offer at $63 per
share of E'town stock (3 shares of Company B stock at $21 per share) or E'town
would have the right to terminate the merger. In reviewing this proposal, the
E'town board of directors became concerned about the high price to earnings and
market to book multiples of Company B's stock relative to its water utility peer
group and Company B's prospects for sustaining those multiples given falling
interest rates and the trend of declining authorized rates of return (and
therefore, profitability) in the regulated water utility industry. In addition,
the board did not place significant value on the termination right because if
termination were to occur, E'town would likely be in a weakened negotiating
position if other acquisition offers developed.

     E'town communicated these concerns about the sustainability of the price of
Company B's stock to Company B and suggested that Company B (i) add a cash
component to its offer and/or (ii) make a fixed-value offer in stock. Company B
responded with a fixed-value offer of $68 per share in stock, subject to Company
B's right to terminate if its stock price fell below $21 per share. Company B
declined to add a cash component to its offer. E'town's financial advisor
advised the board that the small margin between the then current trading range
of Company B's stock and the floor price of $21 was insufficient cushion against
a further drop in Company B's stock price. Discussions with Company B
subsequently ended.

     In July 1999, the board authorized management to concentrate on
negotiations with Company A to determine if an acceptable agreement could be
reached for an acquisition of E'town by Company A, while continuing a dialogue
with Company B. Company A suggested a transaction whereby it would pay $65 for
each share of E'town common stock, in cash or common stock of Company A, at the
election of E'town shareholders. The fixed-value offer was subject to a collar
whereby the offer converted to a fixed exchange

                                       16
<PAGE>   23

ratio if the market price of Company A's stock exceeded $43 per share or fell
below $34 per share. During July 1999, the market price of Company A's stock
traded in the range of $38 3/8 to $42 1/16 per share. After an intensive period
of due diligence and discussions, in early August 1999 the price of Company A's
stock fell to $36-$37 per share and Company A withdrew from further negotiations
with E'town. Company A cited the decline in the trading range of Company A's
stock and the high acquisition prices being paid for water utility companies as
major reasons for breaking off discussions, and stressed that it had found
nothing in its evaluation of E'town that contributed to its decision.

     At the September 8, 1999 meeting of the corporate planning committee of the
E'town board of directors, Anne Evans Estabrook, E'town's Chairman, and Andrew
M. Chapman, E'town's President, reported on the results of an initial meeting
held in New York in August at the request of Thames Water Plc, which had earlier
expressed an interest in initiating discussions with E'town. At the invitation
of Thames, Mrs. Estabrook and Mr. Chapman visited Thames's headquarters in
London, England in early September. Mrs. Estabrook and Mr. Chapman told the
committee that they were impressed with Thames's management and operations. They
recommended that E'town enter into a confidentiality and standstill agreement
with Thames in order to provide Thames with nonpublic information regarding
E'town, with a view to continuing further discussions. The committee and the
board of directors authorized management to enter into such agreements with
Thames and any additional candidates identified by Mrs. Estabrook and Mr.
Chapman in the course of E'town's continued review of strategic alternatives.
E'town and Thames executed a confidentiality and standstill agreement on
September 9, 1999. From mid-September until mid-October 1999, Mrs. Estabrook and
Mr. Chapman had further discussions with management of Thames and with Company
B.

     At the E'town board of directors meeting on October 14, 1999, the board
received a report on the progress of these discussions. Mr. Chapman stated that
while Company B was still interested in pursuing discussions, it had been unable
to address satisfactorily the issues previously raised by the board of directors
concerning mitigation of the risk of a future reduction in its high stock market
valuation. Mrs. Estabrook reported that Thames had expressed a continuing
interest in pursuing discussions with E'town. Thames's chief executive officer
had indicated to Mrs. Estabrook and Mr. Chapman that, subject to the outcome of
an in-depth due diligence review and negotiation of a mutually acceptable merger
agreement, he would be willing to recommend to the Thames board of directors
that Thames make an all-cash offer for E'town within a price range of up to
$68.00 per share. Thames also requested a period of exclusivity to conduct those
activities.

     In response to this request, the board discussed the uncertain prospects
for reaching agreements with other potential candidates who had been tentatively
identified by management but who had not yet begun serious discussions with
E'town, including the two other companies mentioned above. The board also
reviewed the status of Company B's interest, and the absence of any momentum in
those discussions since the summer. The board of directors authorized the grant
to Thames of a 30-day exclusivity period, within which all due diligence
activities and negotiation of a definitive agreement would be substantially
completed. However, the board required that it retain the ability to consider
unsolicited offers for E'town during the exclusivity period, and to terminate
the exclusive arrangements early if E'town determined that Thames was not
prepared to use its reasonable best efforts to reach an agreement for a
combination at a price at the high end of the range previously discussed. A
letter agreement containing these terms and providing for an exclusivity period
until November 15, 1999 was signed with Thames on October 15, 1999. Thereafter,
E'town discontinued its plans to contact additional companies for exploratory
discussions during the exclusivity period. E'town did not receive any
unsolicited proposals during that period.

     From mid-October until mid-November 1999, Thames conducted due diligence,
and E'town made several management presentations to Thames and its advisors.
Counsel for E'town distributed a draft of a merger agreement to Thames and its
advisors, and the parties met to negotiate the terms of the agreement. Counsel
to Thames distributed to Mr. Chapman and his independent counsel a draft of the
employment agreement described under "Interests of Certain Persons in the
Merger," and separate negotiations occurred with respect to that agreement.

     At a regular E'town board of directors meeting held on November 18, 1999,
the board reviewed in detail the status of discussions with Thames. Counsel to
E'town distributed to the directors a substantially final draft

                                       17
<PAGE>   24

of the Merger Agreement and a summary of its principal terms. Representatives of
Salomon Smith Barney reviewed with the board the premiums and multiples to
various indices that would result from an acquisition of E'town within the price
range provided by Thames.

     The board then discussed these presentations and the advantages and
disadvantages of agreeing to a transaction where E'town's shareholders would
receive all cash as opposed to a transaction having a stock component. At the
request of the board, counsel to E'town described the nature of the board's
responsibilities in considering a transaction that would involve a change of
control, and the considerations that the board should take into account in
negotiating the amount of the termination fee described under "The Merger
Agreement -- Termination Fees."

     At the conclusion of this discussion, the board instructed the Chairman and
the President to inform Thames that the board would consider the transaction
further only after the remaining open issues, including the amount of the
proposed termination fee and completion of discussions regarding Mr. Chapman's
employment agreement, were resolved. The board also requested notification that
the Thames board of directors had approved a final offer for the acquisition of
E'town.

     The E'town board of directors met in special session at 5 p.m. the next
day, November 19, 1999. The Chairman reported that the major open issues in the
discussions with Thames had been resolved, and that the Thames board of
directors had approved the proposal to acquire E'town on the terms described in
this proxy statement. Representatives of Salomon Smith Barney made a financial
presentation to the board and delivered to the board its oral opinion (which
opinion was confirmed by delivery of a written opinion dated the date of
execution of the Merger Agreement) to the effect that, as of the date of the
opinion and based on and subject to the matters described in the opinion, the
merger consideration was fair, from a financial point of view, to holders of
E'town common stock.

     After further discussion and consideration, the board of directors
unanimously voted to approve the Merger Agreement and determined that the merger
is in the best interests of E'town's shareholders.

     In a separate vote, with Mr. Chapman abstaining, the board unanimously
approved Mr. Chapman's employment agreement and established the success fee for
Mr. Chapman described under "Interests of Certain Persons in the Merger". The
success fee of $375,000 was established by the board by reference to Mr.
Chapman's cash compensation for 1999 of $320,000 (a base salary of $250,000 plus
a performance-related bonus of $70,000, excluding an additional bonus awarded
for efforts in connection with the Company's response to Hurricane Floyd). Mr.
Chapman's proposed employment contract with Thames provides for a separate
"retention" fee of 20% of Mr. Chapman's 1999 base salary, or $50,000. Since the
bonus payable under the Thames employment contract must be subtracted from the
success fee, the resulting sum is approximately the same as Mr. Chapman's 1999
base salary plus bonus, which is the benchmark used by the board.

     Over the weekend of November 20-21, 1999, the parties finished preparation
of the Merger Agreement and Mr. Chapman's employment agreement and executed and
delivered them. On November 22, 1999, both parties issued press releases
announcing the transaction.

E'TOWN'S REASONS FOR THE MERGER

     For the reasons set out below, your board of directors believes that the
consideration to be paid to you in the merger exceeds the value that E'town
would be able to achieve for its shareholders in the foreseeable future if
E'town were to remain an independent company. Your board of directors has
unanimously approved the Merger Agreement and has determined that the merger is
in the best interests of E'town shareholders. The E'town board unanimously
recommends that you vote FOR approval of the Merger Agreement.

     In determining that the merger is in the best interests of E'town
shareholders, your board consulted with the company's legal and financial
advisors and considered a number of factors, including the following.

          1. The board believes that the current environment of utility
     consolidations in the U.S., including in particular water utility
     acquisitions occurring at attractive prices, provides an optimal time to
     realize value

                                       18
<PAGE>   25

     for E'town shareholders. Market to book value ratios and price to earnings
     ratios for many water utilities, including E'town, are at or near all-time
     highs.

          2. The price of $68.00 per share of common stock being paid by Thames
     represents a premium of approximately 36% over the $49.94 per share average
     closing price of E'town common stock for the 30 calendar days immediately
     preceding the announcement of the merger on November 22, 1999. This price
     also represents a 24% premium over E'town's all-time high closing share
     price of $54.63.

          3. The price of $68.00 in cash per share of common stock being paid by
     Thames exceeds the indicative price discussed with Company A and the value
     believed by the board to be represented by Company B's all-stock offer
     during E'town's previous discussions with these companies.

          4. The E'town board determined that E'town would not be able to
     achieve shareholder value equal to the merger consideration being paid by
     Thames through its current operations, through acquisitions of smaller
     water companies, or through a merger or other business combination with a
     similarly-sized water company. The board believes that E'town requires a
     substantially larger platform in order to compete with the larger companies
     that are aggressively targeting the U.S. market for water services. The
     board does not believe that a long-term strategy of pursuing acquisitions,
     even if successful, would be likely to achieve a platform comparable to
     that provided by Thames, or result in a stock price that exceeds the price
     which can be achieved now through sale of the company to Thames.

          5. The board considered the financial presentation of Salomon Smith
     Barney, including its written opinion dated November 21, 1999, as to the
     fairness, from a financial point of view, of the merger consideration to
     the holders of E'town common stock, as described below under the caption
     "Opinion of E'town's Financial Advisor".

          6. The board determined that Thames is financially capable of
     completing the merger.

          7. The board took into account the terms and conditions of the Merger
     Agreement, including those relating to the ability of the E'town board to
     consider unsolicited offers from third parties prior to approval of the
     Merger Agreement by E'town shareholders.

          8. The Merger Agreement requires the affirmative vote of a majority of
     the votes cast by the holders of shares of E'town common stock entitled to
     vote on that agreement, which, following the distribution of this proxy
     statement, allows for an informed vote of E'town's public shareholders on
     the transaction.

     As part of its evaluation process, the board considered the advantages and
disadvantages of a transaction with a foreign acquiror instead of a domestic
one. The board analyzed this issue by reference to E'town's three primary
constituencies: shareholders; customers and communities served; and employees.

     With regard to shareholders, the board of directors considered (i) the
likely willingness of regulators to approve an acquisition by a foreign buyer
and (ii) the type of consideration that could be offered by foreign and domestic
buyers and the related federal tax consequences. While the board realized that
there could be some initial concern among regulators about foreign ownership of
the Company, it determined that the purchaser's expertise in the water utility
field and commitment to community and customer issues would ultimately outweigh
these concerns. At the time the board was considering the Thames offer, another
U.S. water utility was in the process of being acquired by an offshore
purchaser, and substantial interests in two other U.S. water companies were (and
are) owned by French companies. Furthermore, the board of directors determined
that regulators would recognize that Thames would need to maintain the
operations of E'town at a high level to achieve its own business expansion goals
in the U.S.

     Thames was not prepared to offer any consideration other than cash, and the
board believed that it was not appropriate for E'town's primarily retail and
income-oriented shareholders to be required to take stock in a company traded
overseas and subject to different accounting and disclosure rules. While the
board recognized the tax advantages to its shareholders of a stock-for-stock
exchange, it also realized that even after conducting substantial due diligence
on any company offering stock, any stock-for-stock exchange would expose holders
of E'town common stock to the risks of the future, combined operation.
Accordingly, the board determined that the cash consideration offered by Thames
was in the best interests of E'town shareholders.

                                       19
<PAGE>   26

     With regard to customer and community concerns, the board determined that
any purchaser must have demonstrated, through its existing operations,
commitment to water quality (if in the potable water business), environmental
quality, and customer service. The board believed that the level of a
purchaser's commitment was better assessed by evaluating its business activities
and investments in each of these areas than by making judgments based on where
its operations are based. The board believed that any concerns among community
and political leaders about a non-U.S. purchaser could be adequately addressed
by focusing on the purchaser's commitments to these values and on its overall
expertise as a water utility.

     With regard to employees, the board believed that affiliation with a
company with substantial expertise in water utility operations worldwide would
provide those E'town employees willing to embrace change with expanded career
opportunities and the opportunities to learn new operating skills and management
techniques.

     The E'town board of directors has also considered (1) the risk that the
merger would not be consummated, (2) the effect of the public announcement of
the merger on E'town's ability to retain employees, and on the trading price of
E'town common stock, (3) the substantial time and effort that will be required
of management to complete the merger, (4) the possible impact of the merger on
E'town employees, and (5) the possibility that certain provisions of the Merger
Agreement might have the effect of discouraging other persons potentially
interested in a combination with E'town from pursuing such an opportunity (e.g.
E'town's potential obligation to pay to Thames a substantial termination fee and
the provision whereby E'town is prohibited from discussing such opportunities
once E'town's shareholders have voted to approve the Merger Agreement). The
E'town board of directors has concluded that the potential benefits of the
merger outweigh these considerations.

     In view of the wide variety of factors considered in connection with its
evaluation of the proposed merger, the board of directors did not find it
practicable to, and did not, quantify, rank or otherwise attempt to assign
relative weights to the foregoing factors. The board of directors viewed its
position and recommendation as being based on the totality of the information
presented to and considered by it. While the foregoing discussion of the
information and factors considered by the board of directors is not intended to
be all-inclusive, it does constitute a summary of all material information
considered by the board of directors in determining to recommend approval of the
Merger Agreement.

     E'town does not, as a matter of course, make public its forecasts or
projections as to the future sales, earnings or other income statement data,
cash flows or balance sheet and financial position information. The above
summary of these projections is included in this proxy statement solely because
the projections were made available to Thames. The projections do not reflect
any of the effects of the merger or other future adjustments that may be
appropriate concerning E'town and its assets, business, operations, properties,
policies, corporate structure, capitalization and management in light of the
circumstances then existing.

     The most significant assumptions used by E'town in developing the financial
projections were:

     Regulated Utilities

     - Annual revenue growth of 1.5% from customer growth (assumes average
       weather conditions).

     - Annual expense increases of 4% in labor costs and 2% in other expenses
       except power and purchased water.

     - $14 million of rate increases effective in the period June 1999 - January
       2002.

                                       21
<PAGE>   28

     - Capital expenditures of $215 million in the projection period.

     - $30 million of new long-term debt at interest rates of 5.5% - 7%.

     Contract Operations

     - Rate increases for Liberty and Edison per contract.

     - Capital expenditures of $9 million in the projection period.

     Other

     - AWM revenues of $13 million - $15 million annually in the projection
       period.

     - Gains on sales of land by Properties of $9 million in the projection
       period.

     - Proceeds of $52 million from issuances of equity and $20 million (6.5%
       interest rate) from issuance of debt by E'town.

     During the period when Thames conducted due diligence on E'town, E'town
provided Thames with revised projections with regard to one unregulated
subsidiary which had the effect of reducing earnings per share and consolidated
net income by approximately 1.5% in each of the years forecast.

     Other than as described above, E'town has not updated the projections to
reflect changes that have occurred since their preparation. E'town believes the
assumptions made were reasonable at the time the projections were prepared,
given the information known by its management at such time.

     E'town did not prepare the projections with a view toward public disclosure
or compliance with published guidelines of the Securities and Exchange
Commission or the American Institute of Certified Public Accountants regarding
forward-looking information or generally accepted accounting principles.
E'town's independent auditors have not, and other independent accountants have
not, compiled, examined or performed any procedure with respect to the
prospective financial information contained in the projections, and they have
not expressed any opinion or given any form of assurance on the projections or
their achievability, and assume no responsibility for and disclaim any
association with, such prospective information. Furthermore the projections
necessarily make numerous assumptions, many of which are beyond the control of
E'town and may not prove to have been and may no longer be accurate.
Additionally, this information does not reflect revised prospects for E'town's
businesses, changes in the general business and economic conditions, or any
other transaction or event that has occurred or that may occur and that was not
anticipated at the time the projections were prepared. Accordingly, the
projections are not necessarily indicative of current value or future
performance, which may be significantly more favorable or less favorable than
described below, and should not be regarded as a representation that they will
be achieved.

     THE PROJECTIONS ARE NOT GUARANTEES OF PERFORMANCE. THEY INVOLVE RISKS,
UNCERTAINTIES AND ASSUMPTIONS. THE FUTURE RESULTS OF E'TOWN AND E'TOWN'S VALUE
MAY MATERIALLY DIFFER FROM THE PROJECTIONS. MANY OF THE FACTORS THAT WILL
DETERMINE THESE RESULTS AND VALUES ARE BEYOND E'TOWN'S ABILITY TO CONTROL OR
PREDICT. HOLDERS OF E'TOWN'S COMMON STOCK ARE CAUTIONED NOT TO PLACE UNDUE
RELIANCE ON THE PROJECTIONS. THERE CAN BE NO ASSURANCE THAT THE PROJECTIONS WILL
BE REALIZED OR THAT E'TOWN'S FUTURE FINANCIAL RESULTS WILL NOT MATERIALLY VARY
FROM THE PROJECTIONS. E'TOWN DOES NOT INTEND TO UPDATE OR REVISE THE
PROJECTIONS.

OPINION OF E'TOWN'S FINANCIAL ADVISOR

     E'town retained Salomon Smith Barney to act as its financial advisor in
connection with the proposed merger. In connection with its engagement, E'town
requested that Salomon Smith Barney evaluate the fairness, from a financial
point of view, of the consideration to be received in the merger by holders of
E'town common stock. On November 19, 1999, at a meeting of the E'town board held
to evaluate the proposed merger, Salomon Smith Barney delivered to the E'town
board an oral opinion (which opinion was confirmed by delivery of a written
opinion dated November 21, 1999, the date of execution of the Merger Agreement)
to

                                       22
<PAGE>   29

the effect that, as of the date of the opinion and based on and subject to the
matters described in the opinion, the merger consideration was fair, from a
financial point of view, to the holders of E'town common stock.

     In arriving at its opinion, Salomon Smith Barney:

     - reviewed the Merger Agreement and related documents;

     - held discussions with senior officers, directors and other
       representatives and advisors of E'town and with senior officers and other
       representatives and advisors of Thames concerning the business,
       operations and prospects of E'town;

     - examined publicly available business and financial information relating
       to E'town;

     - examined financial forecasts and other information and data for E'town
       which were provided to or otherwise discussed with Salomon Smith Barney
       by the management of E'town;

     - reviewed the financial terms of the merger as described in the Merger
       Agreement in relation to, among other things, current and historical
       market prices and trading volumes of E'town common stock, the historical
       and projected earnings and other operating data of E'town, and the
       capitalization and financial condition of E'town;

     - considered, to the extent publicly available, the financial terms of
       other transactions recently effected which Salomon Smith Barney
       considered relevant in evaluating the merger;

     - analyzed financial, stock market and other publicly available information
       relating to the businesses of other companies whose operations Salomon
       Smith Barney considered relevant in evaluating those of E'town; and

     - conducted other analyses and examinations and considered other financial,
       economic and market criteria as Salomon Smith Barney deemed appropriate
       in arriving at its opinion.

     In rendering its opinion, Salomon Smith Barney assumed and relied, without
independent verification, on the accuracy and completeness of all financial and
other information and data that it reviewed or considered. With respect to these
financial forecasts and other information and data, the management of E'town
advised Salomon Smith Barney that they were reasonably prepared on bases
reflecting the best currently available estimates and judgments of the
management of E'town as to the future financial performance of E'town.

     Salomon Smith Barney assumed, with E'town's consent, that in the course of
obtaining the necessary regulatory approvals for the merger, no limitations,
restrictions or conditions would be imposed that would have a material adverse
effect on the contemplated benefits of the merger to E'town. Salomon Smith
Barney did not make and was not provided with an independent evaluation or
appraisal of the assets or liabilities, contingent or otherwise, of E'town, and
did not make any physical inspection of the properties or assets of E'town.

     Salomon Smith Barney was not requested to, and did not, solicit third party
proposals for the possible acquisition of all or a part of E'town. Salomon Smith
Barney expressed no view as to, and its opinion does not address, the relative
merits of the merger as compared to any alternative business strategies that
might exist for E'town or the effect of any other transaction in which E'town
might engage. Salomon Smith Barney's opinion was necessarily based on
information available, and financial, stock market and other conditions and
circumstances existing and disclosed to Salomon Smith Barney, as of the date of
its opinion. Although Salomon Smith Barney evaluated the merger consideration
from a financial point of view, Salomon Smith Barney was not asked to and did
not recommend the specific consideration payable in the merger, which was
determined through negotiation between E'town and Thames. No other instructions
or limitations were imposed by E'town on Salomon Smith Barney with respect to
the investigations made or procedures followed by Salomon Smith Barney in
rendering its opinion.

     THE FULL TEXT OF SALOMON SMITH BARNEY'S WRITTEN OPINION DATED NOVEMBER 21,
1999, WHICH DESCRIBES THE ASSUMPTIONS MADE, MATTERS CONSIDERED AND LIMITATIONS
ON THE REVIEW UNDERTAKEN, IS ATTACHED TO THIS DOCUMENT AS APPENDIX B AND IS
INCORPORATED INTO THIS DOCUMENT BY REFERENCE. SALOMON SMITH BARNEY'S

                                       23
<PAGE>   30

OPINION IS DIRECTED TO THE E'TOWN BOARD AND RELATES ONLY TO THE FAIRNESS OF THE
MERGER CONSIDERATION FROM A FINANCIAL POINT OF VIEW, DOES NOT ADDRESS ANY OTHER
ASPECT OF THE MERGER OR ANY RELATED TRANSACTION AND DOES NOT CONSTITUTE A
RECOMMENDATION TO ANY SHAREHOLDER WITH RESPECT TO ANY MATTER RELATING TO THE
PROPOSED MERGER.

     In preparing its opinion, Salomon Smith Barney performed a variety of
financial and comparative analyses, including those described below. The summary
of these analyses is not a complete description of the analyses underlying
Salomon Smith Barney's opinion. The preparation of a fairness opinion is a
complex analytical process involving various determinations as to the most
appropriate and relevant methods of financial analysis and the application of
those methods to the particular circumstances and, therefore, a fairness opinion
is not readily susceptible to summary description. Accordingly, Salomon Smith
Barney believes that its analyses must be considered as a whole and that
selecting portions of its analyses and factors, without considering all analyses
and factors, could create a misleading or incomplete view of the processes
underlying its analyses and opinion.

     In its analyses, Salomon Smith Barney considered industry performance,
general business, economic, market and financial conditions and other matters
existing as of the date of its opinion, many of which are beyond the control of
E'town. No company, transaction or business used in those analyses as a
comparison is identical to E'town or the proposed merger, and an evaluation of
those analyses is not entirely mathematical. Rather, the analyses involve
complex considerations and judgments concerning financial and operating
characteristics and other factors that could affect the acquisition, public
trading or other values of the companies, business segments or transactions
analyzed.

     The estimates contained in Salomon Smith Barney's analyses and the
valuation ranges resulting from any particular analysis are not necessarily
indicative of actual values or predictive of future results or values, which may
be significantly more or less favorable than those suggested by its analyses. In
addition, analyses relating to the value of businesses or securities do not
necessarily purport to be appraisals or to reflect the prices at which
businesses or securities actually may be sold. Accordingly, Salomon Smith
Barney's analyses and estimates are inherently subject to substantial
uncertainty.

     Salomon Smith Barney's opinion and analyses were only one of many factors
considered by the E'town board in its evaluation of the merger and should not be
viewed as determinative of the views of the E'town board or management with
respect to the merger consideration or the proposed merger.

     The following is a summary of the material financial analyses performed by
Salomon Smith Barney in connection with the rendering of its opinion dated
November 21, 1999:

  Selected Companies Analysis.

     Using publicly available information, Salomon Smith Barney also analyzed
the market values and trading multiples of the following six selected publicly
traded companies in the water utilities industry (collectively, the "Selected
Water Utilities"):

    - American Water Works Company, Inc.
     - Philadelphia Suburban Corporation
     - California Water Service Group
     - American States Water Company
     - Middlesex Water Company
     - Connecticut Water Services, Inc.

     All multiples were based on closing stock prices on November 18, 1999.
Estimated financial data for the Selected Water Utility Companies were based on
research analysts' estimates, and estimated financial data for E'town were based
on internal estimates of the management of E'town. Salomon Smith Barney
compared, among other things, market values as multiples of latest 12 months and
estimated calendar years 1999 and 2000 earnings per share and latest 12 months
book value as of September 30, 1999. Salomon Smith Barney then applied a range
of selected multiples derived from the Selected Water Utility Companies of 19.0x
to 22.0x latest 12 months earnings per share, 19.0x to 21.0x estimated 1999
earnings per share, 18.0x to 21.0x
                                       24
<PAGE>   31

estimated 2000 earnings per share and 1.90x to 2.25x latest 12 months book value
to corresponding financial data for E'town. Based on approximately the average
of the implied equity values derived from that financial data, this analysis
resulted in an equity reference range for E'town of approximately $47.00 to
$55.00 per share, as compared to the merger consideration of $68.00 per share.

     Salomon Smith Barney also reviewed the trading multiples of selected gas
distribution utilities and integrated or distribution oriented electric
utilities. These utilities industries are similarly regulated as to equity rates
of return and have growth characteristics similar to those of the water
utilities industry. Using publicly available information, Salomon Smith Barney
analyzed the market values and trading multiples of the following 23 selected
publicly traded gas distribution and electric utilities (collectively, the
"Selected Gas and Electric Utilities"):

</TABLE>

     All multiples were based on closing stock prices on November 18, 1999.
Estimated financial data for the Selected Gas and Electric Utilities were based
on research analysts' estimates, and estimated financial data for E'town were
based on internal estimates of the management of E'town. Salomon Smith Barney
compared, among other things, equity market values as multiples of latest 12
months and estimated calendar years 1999 and 2000 earnings per share and latest
12 months book value as of June 30, 1999. Salomon Smith Barney then applied a
range of selected multiples, based on approximately the median multiples derived
from the Selected Gas and Electric Utilities, of 12.5x to 16.5x latest 12 months
earnings per share, 12.0x to 16.0x estimated 1999 earnings per share, 11.0x to
14.0x estimated 2000 earnings per share and 1.60x to 1.80x latest 12 months book
value to corresponding financial data for E'town. Based on approximately the
average of the implied equity values derived from that financial data, this
analysis resulted in an equity reference range for E'town of approximately
$35.00 to $41.00 per share, as compared to the merger consideration of $68.00
per share.

  Precedent Transactions Analysis.

     Using publicly available information, Salomon Smith Barney reviewed the
purchase prices and implied transaction value multiples paid or proposed to be
paid in the following eight selected transactions in the water utilities
industry (the "Selected Transactions"):

</TABLE>

     Salomon Smith Barney compared purchase prices in the Selected Transactions
as multiples of latest 12 months, forward to year-end and the forward year
thereafter net income and latest 12 months book value. All multiples were based
on publicly available financial information for the relevant transaction.
Salomon Smith Barney then applied a range of selected multiples derived from the
Selected Transactions of 22.0x to 30.0x latest 12 months net income, 22.0x to
28.0x forward to year-end net income, 21.0x to 26.0x forward year thereafter net
income and 2.50x to 3.00x latest 12 months book value to E'town's latest 12
months and estimated calendar years 1999 and 2000 earnings per share and latest
12 months book value as of September 30, 1999, respectively. Based on
approximately the average of the implied equity values derived from that
financial data, this analysis resulted in an implied equity reference range for
E'town of approximately $57.00 to $72.50 per share, as compared to the merger
consideration of $68.00 per share.

  Discounted Cash Flow Analysis.

     Salomon Smith Barney performed a discounted cash flow analysis of E'town's
projected free cash flows during fiscal years 1999 through 2003 based on
internal estimates of E'town's management, both before and after giving effect
to hypothetical synergies which E'town's management indicated might be possible
in a merger of E'town with another water utility with major operations in New
Jersey. Salomon Smith Barney derived an implied equity reference range for
E'town at the end of the five-year period by applying to E'town's 2003 net
income a range of selected terminal value multiples of 12.5x to 16.5x (based on
the Selected Gas and Electric Utilities) and 19.0x to 23.0x (based on the
Selected Water Utilities). The cash flows and terminal values of E'town were
then discounted to present value using selected discount rates ranging from
6.75% to 8.75% to derive an implied equity reference range for E'town. Applying
a terminal value multiple range of 12.5x to 16.5x, this analysis resulted in an
implied equity reference range for E'town of approximately $39.00 to $47.50 per
share (before taking into account hypothetical synergies) and approximately
$42.00 to $50.00 per share (after taking into account hypothetical synergies),
as compared to the merger consideration of $68.00 per share. Applying a terminal
value multiple range of 19.0x to 23.0x, this analysis resulted in an equity
reference range for E'town of approximately $56.00 to $64.50 per share (before
taking into account hypothetical synergies) and approximately $58.50 to $67.00
per share (after taking into account hypothetical synergies), as compared to the
merger consideration of $68.00 per share.

  Other Factors.

     In rendering its opinion, Salomon Smith Barney also reviewed and
considered, among other things:

     - historical and projected financial data for E'town;

     - research analysts' reports for E'town, including earnings and growth rate
       estimates of those analysts;

     - a comparison of the trading multiples, historical market prices, growth
       statistics and trading volumes of selected water, gas and electric
       utility companies and the relationship between movements in E'town

                                       26
<PAGE>   33

       common stock and movements in the common stock of selected water, gas and
       electric utility companies;

     - the average earnings yield of selected water utility companies relative
       to the yield of 10-year treasury bonds over the period April 1990 to
       November 1999; and

     - a business, financial and shareholder profile of Thames.

  Miscellaneous.

     Under the terms of its engagement, E'town has agreed to pay Salomon Smith
Barney for its financial advisory services upon completion of the merger an
aggregate fee based on a percentage of the total consideration, including
liabilities assumed, payable in the merger. The fee payable to Salomon Smith
Barney is currently estimated to be approximately $4.5 million. E'town also has
agreed to reimburse Salomon Smith Barney for reasonable travel and other
out-of-pocket expenses incurred by Salomon Smith Barney in performing its
services, including the reasonable fees and expenses of its legal counsel, and
to indemnify Salomon Smith Barney and related persons against liabilities,
including liabilities under the federal securities laws, arising out of its
engagement.

     In the ordinary course of business, Salomon Smith Barney and its affiliates
may actively trade or hold the securities of E'town and Thames for their own
account or for the account of customers and, accordingly, may at any time hold a
long or short position in those securities. Salomon Smith Barney has provided
investment banking services to E'town unrelated to the proposed merger by way of
acting as re-marketing agent for E'town's $25,000,000 New Jersey Development
Economic Authority Water Facility Bonds (Elizabethtown Water Company
Project -- 1997, Series B), for which services Salomon Smith Barney receives
compensation in the amount of $25,000 per year. In addition, Salomon Smith
Barney and its affiliates, including Citigroup Inc. and its affiliates, may
maintain relationships with E'town, Thames and their respective affiliates.

     Salomon Smith Barney is an internationally recognized investment banking
firm and was selected by E'town based on its experience and expertise in merger
and acquisition transactions generally and in the utility industry in
particular. Salomon Smith Barney regularly engages in the valuation of
businesses and their securities in connection with mergers and acquisitions,
negotiated underwritings, competitive bids, secondary distributions of listed
and unlisted securities, private placements and valuations for estate, corporate
and other purposes.

EFFECTIVE TIME

     The merger will become effective when the parties to the Merger Agreement
file a certificate of merger in the office of the Secretary of the State of New
Jersey in accordance with the New Jersey Business Corporation Act, or at a later
time that Thames and E'town may specify in the certificate of merger (the
"Effective Time").

     The merger can not become effective before the date of the Special Meeting
of E'town shareholders. If the Merger Agreement is approved at the Special
Meeting, the Effective Time will occur as promptly as possible after
satisfaction or waiver of the remaining conditions to the merger contained in
the Merger Agreement, including the receipt of regulatory approvals.

CERTIFICATE OF INCORPORATION AND BY-LAWS

     The certificate of incorporation of E'town in effect immediately prior to
the Effective Time will become the certificate of incorporation of the surviving
company until it is amended. The by-laws of E'town in effect immediately prior
to the Effective Time will be the by-laws of the surviving company until they
are amended.

DIRECTORS AND OFFICERS

REGULATORY APPROVALS

     The parties must comply with federal and state regulatory requirements
before they can complete the merger. Although there can be no guarantee that the
parties will obtain the requisite consents or approvals on a timely basis, or at
all, we believe that the necessary approvals can be obtained before the fourth
quarter of 2000. A discussion of the principal regulatory requirements follows.

  New Jersey Board of Public Utilities.

     E'town's public utility subsidiaries are subject to the jurisdiction of The
New Jersey Board of Public Utilities (the "BPU"). E'town and Thames have filed a
joint petition with the BPU requesting approval for Thames to acquire control of
E'town. The BPU will consider whether Thames is financially, technologically and
managerially suitable to control E'town and its subsidiaries as well as the
ability of E'town to continue to provide safe, adequate and reliable service to
the public through its plant, equipment, and manner of operation were the
application to be approved.

     E'town believes that the joint petition to the BPU fully demonstrates that
the merger will meet the requirements of New Jersey law. Nonetheless, opposition
to the application is possible. It is expected that the New Jersey Office of
Ratepayer Advocate will appear in and participate in the BPU's merger approval
review process. During the course of the BPU's review of the petition, it is
expected that the parties will be allowed to conduct discovery, which will
likely consist of interrogatories addressed to E'town and Thames by BPU staff
and other intervening parties. Also, it is expected that the parties and the
public will have an opportunity to comment on whether the petition should be
approved.

     E'town can give no assurance that the necessary BPU approvals will be
obtained in a timely manner or at all. Moreover, we cannot guarantee that the
BPU approvals will not include conditions that, if accepted, would result in a
material adverse effect on the surviving company. If so, Thames will not be
obligated to complete the merger.

  Antitrust.

     Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended
(the "Hart-Scott Act"), and the rules promulgated under it by the U.S. Federal
Trade Commission, we cannot complete the merger until we have notified and
furnished certain information to the Federal Trade Commission and the Antitrust
Division of the U.S. Department of Justice, and satisfied specified waiting
period requirements. Thames and E'town will file notification and report forms
under the Hart-Scott Act with the Federal Trade Commission and the Antitrust
Division of the U.S. Department of Justice. Even after the waiting period
expires or is terminated, the Federal Trade Commission and the Antitrust
Division of the U.S. Department of Justice may still challenge the merger on
antitrust grounds, either before or after the merger is completed. There can be
no assurance that such a challenge, if made, would not be successful. E'town and
Thames believe, however, that the merger would not violate federal antitrust
laws.

  Industrial Site Recovery Act.

     The New Jersey Industrial Site Recovery Act ("ISRA") imposes certain filing
and clearance requirements in respect of the closing, sale or transfer of most
industrial sites in New Jersey falling within specific Standard Industrial
Classification codes, including a code covering the operations of E'town.
However, regulations of the New Jersey Department of Environmental Protection
(the "NJDEP"), which administers ISRA, specifically exempt water supply and
sewage treatment operations from the terms of ISRA and its implementing
regulations. E'town has requested from the NJDEP a Letter of Non-Applicability
for the merger with respect to ISRA, and has been advised by outside counsel
that it should receive such a letter in due course.

                                       28
<PAGE>   35

  Obligations to Obtain Regulatory Approvals.

     Under the Merger Agreement, both Thames and E'town have agreed to use all
commercially reasonable efforts to obtain all regulatory and governmental
approvals necessary or advisable to complete the merger.

INJUNCTIONS

     The obligations of each of Thames and E'town to complete the merger is
subject to the condition that there is no law, regulation or injunction in
effect that would prohibit the completion of the merger.

INTERESTS OF CERTAIN PERSONS IN THE MERGER

     When you consider the recommendations of the board of directors, you should
realize that some board members and officers of E'town have interests that may
conflict with your own interests as a shareholder. The board of directors was
aware of these interests and considered them along with other matters in
recommending that you vote to approve the Merger Agreement.

  Surviving Company Directors and Officers.

     Certain officers of E'town will hold positions within the surviving company
after the merger. See "The Merger Agreement -- Corporate Governance Matters" at
page 34.

  Employment Agreement.

     E'town has entered into an employment agreement with its current President
and President of Elizabethtown, Andrew M. Chapman, which, following the merger,
will replace Mr. Chapman's existing change in control agreement with E'town.

     Under the terms of the new employment agreement, Mr. Chapman will be
employed as President and Chief Executive Officer of both E'town and
Elizabethtown after the merger on terms which include the following:

     - employment for a term of at least three years with subsequent automatic
       one-year renewal terms;

     - a seat on the boards of E'town, Thames Water North America, Inc. and
       Elizabethtown, and, if Thames establishes a board of directors for its
       businesses in the Americas, a seat on that board;

     - annual base salary of $270,000 (compared to $250,000 under Mr. Chapman's
       current employment arrangement with E'town), which, unless the employment
       agreement has been terminated, may be increased by the compensation
       committee of the E'town board of directors, on the first anniversary of
       the employment agreement and on every anniversary thereafter, by such
       amount as the compensation committee may, in its sole discretion,
       determine;

     - an annual bonus consisting of the following:

        - a performance bonus in the form of an annual cash bonus equal to 10%
          of Mr. Chapman's then salary, if Mr. Chapman achieves a specified
          performance target of which 90% will be based on net profits before
          taxes based on an agreed annual budget, and 10% will be based on
          measurable customer service/water quality targets as determined by the
          compensation committee. Such performance bonus will be increased by 5%
          of Mr. Chapman's then salary for each 5% increment over the
          performance target achieved up to a maximum of 50% of such salary;

        - a customer bonus in the form of an annual cash bonus equal to 12 1/2%
          of Mr. Chapman's then salary for each net increase of 7,500 customer
          metered connections to E'town's base customer level in the prior year.
          Wholesale customer metered connections will be credited at a rate of
          50% of retail customer metered connections;

        - subject to the terms of Thames's equity-based compensation plan, an
          annual grant of restricted shares of the stock of Thames of up to 20%
          of Mr. Chapman's then salary. Each grant will vest

                                       29
<PAGE>   36

          over a four-year period upon the attainment of performance goals
          specified in accordance with the plan or attainment of age 65 by Mr.
          Chapman;

       Under E'town's current arrangement with Mr. Chapman, Mr. Chapman has an
       annual bonus target of 30% of base salary, payments under which are based
       on rates of return on equity realized by Elizabethtown and other goals
       set by the E'town board.

     - a special retention bonus, payable at the commencement of the employment
       agreement, equal to 20% of Mr. Chapman's salary in effect immediately
       prior to the commencement of the employment agreement in consideration
       for remaining with E'town as its President and Chief Executive Officer;

     - entitlement to participate in all benefit, pension, savings, welfare,
       perquisite and other plans or arrangements that E'town may make available
       for its senior executive officers, which plans or arrangements shall be
       no less favorable to Mr. Chapman than those provided to him prior to the
       merger;

     - insurance and indemnification by E'town against expenses and liabilities
       incurred by Mr. Chapman in connection with proceedings instituted against
       him by reason of his officership with the company;

     - for the period during which he receives payments from E'town under the
       employment agreement, an agreement by Mr. Chapman not to take certain
       actions regarding entities which compete with the company; and

     - customary conditions regarding the use of confidential information.

     Under the new employment agreement, Mr. Chapman's severance package depends
on the reason for his termination of employment. Mr. Chapman may voluntarily
terminate his employment within a six-month period commencing on the earlier of
(i) the date of the first BPU rate order received by Elizabethtown after the
merger, or (ii) the date that is 18 months after the merger and receive
continued salary and benefits for a period of 24 months.

     If, during the agreement's initial term of three years, Mr. Chapman
terminates his employment under circumstances constituting good reason (as
defined in the employment agreement) or E'town terminates his employment other
than for death, disability or cause (as defined in the employment agreement):

     - Mr. Chapman will receive continued salary, incentive compensation and
       benefits for a period of 30 months;

     - any of Mr. Chapman's unvested restricted stock and stock options will
       immediately vest and all restrictions on any restricted stock or stock
       options held by him will be voided; and

     - he will obtain full vesting of retirement benefits under E'town's
       Supplemental Executive Retirement Plan (the "SERP"), and, if he has not
       attained the age of 65, he will be bridged to that age for purposes of
       vesting of the normal retirement provisions of the SERP, and will be
       granted an additional 15 years of service for purposes of the benefit
       accrual under the SERP. In addition, he will become entitled to make an
       early payout election under the SERP if he has completed 25 years of
       service with the company (which includes the 15 additional years referred
       to above).

     If the amounts payable by E'town to Mr. Chapman under the agreement are
subject to the excise tax applicable to "parachute payments" under Sections 280G
and 4999 of the Internal Revenue Code, E'town will pay Mr. Chapman an additional
amount so that, after payment of such excise tax, he receives a sum equal to the
original pre-tax severance payment.

  Success Fee.

     The E'town board of directors has resolved that, in recognition of the
substantial additional efforts that will be necessary to consummate the merger
and the benefits accruing to the shareholders if the merger occurs, Mr. Chapman
will be awarded a success fee for bringing the merger to completion in the
amount of $375,000 (less any similar bonus or fee payable under the employment
agreement mentioned above).

                                       30
<PAGE>   37

  Change in Control Agreements.

     E'town has previously entered into Change in Control Agreements with Gail
P. Brady, Walter M. Braswell, James E. Cowley, Dennis W. Doll, Anne Evans
Estabrook, Beth Gates, Robert W. Kean, III, Edward D. Mullen, Henry S.
Patterson, III, Joseph E. Stroin, Jr., Norbert Wagner (the "Officers") and
Andrew M. Chapman. The intent of these agreements is to ensure continuity in the
management of E'town's operations in the event of a change in control (as
defined in the agreements). Following the merger, Mr. Chapman's change in
control agreement will be replaced by the employment agreement described above,
and Mr. Chapman will not be entitled to any payments under his change in control
agreement as a result of the merger. The payments described below, therefore,
will not apply to Mr. Chapman as a result of the merger.

     The merger qualifies as a change in control under these agreements. They
provide that the Officer is entitled to a severance payment if their employment
is terminated:

          (i) within three years of a change in control, by E'town for reasons
     other than for death or cause or disability; or

          (ii) within three years of a change in control, by the Officer due to
     an assignment of materially different duties, significantly more travel,
     diminution in status, position or responsibilities, reduction in
     compensation and benefits, assignment to a location more than 100 miles
     (or, in the case of Anne Evans Estabrook, 50 miles) from the Officer's
     place of employment prior to the change in control, or outside the State of
     New Jersey.

     If their employment is terminated under these circumstances, the Officer's
severance package includes:

     - continued salary, incentive compensation and benefits for a period of 18
       (or, in the case of Anne Evans Estabrook, 30) months;

     - payment on the date of termination of an amount equal to the greater of
       (i) all incentive compensation due prior to the change in control but not
       yet paid and (ii) all incentive compensation due prior to termination of
       employment and not yet paid (or, in the case of Anne Evans Estabrook, the
       sum of such incentive compensation amounts);

     - immediate vesting of any unvested restricted stock and stock options
       granted to the Officer and the voiding of all restrictions on any
       restricted stock or stock options awarded to the Officer which the
       Officer then holds (subject, in the case of all Officers other than Anne
       Evans Estabrook, to the right of the board to amend the terms of such
       benefits); and

     - in the case of all Officers other than Anne Evans Estabrook, full vesting
       of retirement benefits under the SERP and, if the Officer has not
       attained the age of 65, he or she will be bridged to that age for
       purposes of vesting of the normal retirement provisions of the SERP, and
       will be granted an additional 10 years of service for purposes of the
       benefit accrual under the SERP. In addition, the Officers (other than
       Anne Evans Estabrook) are entitled to make an early payout election under
       the SERP if they have completed 25 years of service with the company
       (which includes the 10 additional years referred to above).

     In the case of Anne Evans Estabrook, if the amounts payable by E'town will
be subject to excise tax applicable to "parachute payments" under the federal
tax laws, E'town will pay Mrs. Estabrook an additional amount so that, after
payment of such excise tax, she receives a sum equal to the original pre-tax
severance payment. For all other Officers, the amounts payable will be reduced,
if desired by the Officer, to avoid excise tax applicable to "parachute
payments" under the federal tax laws. Otherwise, the Officer is liable for such
tax.

  Acceleration of Vesting.

     Shares of common stock held by officers and directors of E'town will be
converted into the right to receive the same merger consideration as shares of
common stock held by other shareholders. See "Share Ownership of Management and
Certain Beneficial Owners."

     Stock options held by the officers and directors of E'town will be treated
in the same manner as stock options held by other employees of E'town. At the
Effective Time, all holders of options to purchase E'town common stock (whether
vested or unvested) will receive in exchange for the cancellation of their
options a cash payment per share equal to the excess of $68.00 over the
applicable exercise price, and less any amounts which must be withheld under
applicable tax laws. In addition, each outstanding share of restricted common
stock issued under restricted stock plans will become fully vested at the
Effective Time and will be simultaneously converted into the right to receive a
cash payment of $68.00 per share. As of the record date for the Special Meeting,
the total benefit officers and directors are expected to receive, as a group,
from accelerated vesting of options and restricted common stock under stock
option and restricted stock plans is $1,555,748. In addition, one director of
E'town is expected to receive a sum of $4,340,304 in merger consideration in
exchange for restricted stock of E'town which that director received in
connection with E'town's acquisition of AWM and AWWM. See "The Merger
Agreement -- Additional Agreements -- Stock Options and Restricted Stock."

  Indemnification.

     From the Effective Time onwards, Thames and E'town (as the surviving
company) will ensure that those individuals who were officers, directors or
employees of E'town or any of its subsidiaries at any time before the Effective
Time are indemnified, defended and held harmless (to the fullest extent
permitted by applicable law) for the following:

          (i) all losses, expenses (including reasonable attorney's fees and
     expenses), claims, damages, liabilities or amounts paid in settlement (if
     Thames provided written consent to the settlement) arising out of events
     that occurred at or before the Effective Time and are (at least in part)
     based on the fact that the individual served as a director, officer or
     employee of E'town or one of its subsidiaries; and

          (ii) those losses in (i) above to the extent they are based on or
     pertain to the merger transactions.

     In addition, for six years after the Effective Time, Thames will either:

          (i) maintain policies of liability insurance for the benefit of those
     directors and officers of E'town or its subsidiaries who are currently
     covered; or

          (ii) provide tail coverage (to cover claims received after the policy
     period) for those officers and directors.

     In either case, the terms of the coverage will be at least as favorable as
the terms of the insurance coverage currently provided by E'town. In any year,
however, Thames will not be required to pay more than twice the annual aggregate
premiums that E'town currently pays.

MATERIAL FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

     We have set out below a summary of the material U.S. federal income tax
consequences of the merger to E'town shareholders. It does not purport to
consider all aspects of U.S. federal income taxation that may be relevant to
you. This discussion is based upon the provisions of the Internal Revenue Code,
existing and proposed regulations thereunder, and administrative and judicial
interpretations of the Internal Revenue Code in effect at the date of this
document. Please remember that these are subject to change, possibly with
retroactive effect.

     This discussion does not address the tax consequences of the merger to
shareholders subject to special tax treatment (including insurance companies,
tax-exempt organizations, financial institutions, broker-dealers, foreign
persons, shareholders who hold their E'town shares as part of a hedge,
appreciated financial position,

                                       32

straddle or conversion transaction and shareholders who have acquired their
E'town shares upon the exercise of employee options or otherwise as
compensation), nor does it consider the effect of any foreign, state or local
laws or any U.S. federal laws other than those pertaining to income tax.

     Your receipt of cash upon the exchange of your E'town shares pursuant to
the merger will be a taxable transaction for U.S. federal income tax purposes
and may also be a taxable transaction under applicable state, local, foreign and
other tax laws. Generally you will recognize gain or loss equal to the
difference between the amount of cash received and your adjusted tax basis in
the E'town shares surrendered. If you hold the E'town shares as a capital asset,
the gain or loss recognized will constitute capital gain or loss. Such gain or
loss will be long-term capital gain or loss if your holding period for the
E'town shares surrendered exceeds one year. Long-term capital gains recognized
by individuals and certain other non-corporate E'town shareholders are taxable
at a preferential rate for U.S. federal income tax purposes. There are
limitations on the extent to which you may deduct capital losses from ordinary
income.

     Payments of cash to shareholders will generally be subject to information
reporting requirements. "Backup" withholding at a rate of 31% will apply to your
payments, unless you furnish your taxpayer identification number (which, for a
shareholder who is an individual, is the shareholder's social security number)
in the manner prescribed in the applicable U.S. Treasury regulations, certify
that such number is correct, certify as to no loss of exemption from backup
withholding and meet certain other conditions or are otherwise exempt from
backup withholding. Any amounts withheld under the backup withholding rules will
be allowed as a refund or credit against your U.S. federal income tax liability,
provided that you furnish the required information to the Internal Revenue
Service. Such backup withholding can be avoided if you properly and timely
complete the letter of transmittal that the exchange agent will mail to you (in
connection with the merger) and you include in that letter your correct taxpayer
identification number. See "The Merger Agreement -- Exchange of Stock for Cash."

     YOUR INDIVIDUAL CIRCUMSTANCES MAY AFFECT THE TAX CONSEQUENCES TO YOU OF THE
MERGER. THE PARTICULAR FACTS OR CIRCUMSTANCES THAT MAY AFFECT THE CONSEQUENCES
TO YOU ARE NOT DISCUSSED HERE. ACCORDINGLY, YOU SHOULD CONSULT YOUR TAX ADVISORS
TO DETERMINE THE TAX EFFECT TO YOU OF THE MERGER, INCLUDING THE APPLICATION AND
EFFECT OF FOREIGN, U.S. FEDERAL, STATE, LOCAL OR OTHER TAX LAWS.

ABSENCE OF APPRAISAL RIGHTS

     An appraisal right permits shareholders to receive payment for their shares
in an amount determined by an independent appraisal rather than the
consideration which they otherwise would receive in the transaction. Under New
Jersey state law, E'town shareholders do not have appraisal rights in the
merger. Therefore, if you vote against the merger but the merger is nonetheless
approved by the requisite votes of the shareholders, you will still receive the
$68.00 per share cash consideration rather than an appraised value of the shares
you hold.

                              THE MERGER AGREEMENT

     The following summary of the Merger Agreement is qualified by reference to
the Merger Agreement, which is incorporated by reference and attached as
Appendix A.

GENERAL

     The Merger Agreement provides that Merger Sub will merge with and into
E'town. E'town will be the surviving company, and will continue to conduct its
businesses as an indirect, wholly-owned subsidiary of Thames.

     The closing of the merger will occur on the second business day after the
date upon which all conditions to the merger have been satisfied or waived, or
at such other time as E'town and Thames agree (the "Closing Date"). On the
Closing Date, E'town and Thames will deliver a certificate of merger to the
Secretary of the State of New Jersey for filing. The merger will become
effective upon filing this certificate or at a later time specified in the
certificate (the "Effective Time"). We expect that the Closing Date will occur
prior to the end of 2000.

CORPORATE GOVERNANCE MATTERS

  Directors.

     The directors of Merger Sub immediately prior to the Effective Time, plus
Andrew M. Chapman and Edward A. Clerico, shall be the board of directors of the
surviving company. These directors will hold office until the next annual
shareholders meeting of the surviving company and until their successors are
duly elected or appointed and qualified. Andrew M. Chapman will also be elected
as a director of the subsidiary of Thames which acts as its holding company for
the Thames businesses in North America. Anne Evans Estabrook will be elected as
a member of the international supervisory board of Thames Water International
Services Ltd.

  Officers.

     The officers of E'town immediately prior to the Effective Time will be the
initial officers, holding the same positions, of the surviving company. All
officers will hold their positions until their successors are duly elected or
appointed and qualified.

  Merger Consideration.

     The merger is an "all-cash" transaction in which each issued and
outstanding share of E'town common stock (other than shares owned (i) by E'town
as treasury stock, or (ii) by Thames) will automatically be canceled and cease
to exist and will be converted into the right to receive $68.00 in cash, without
interest. Shares owned by E'town as treasury shares and those owned by Thames
will be canceled without cash or any other consideration being delivered in
exchange for them.

EXCHANGE OF STOCK FOR CASH.

  Paying Agent.

     Prior to the Effective Time, Thames or Merger Sub will designate a bank or
trust company reasonably acceptable to E'town as the paying agent for the
merger. Thames will deposit with the paying agent the amount of cash required to
convert the E'town shares into the merger consideration.

                                       34
<PAGE>   41

  Exchange and Payment Procedures.

     Promptly after the Effective Time, the paying agent will mail to each
record holder of a certificate or certificates representing E'town shares that
have been converted into the right to receive the merger consideration:

          - a letter of transmittal for use in submitting stock certificates to
            the paying agent; and

          - instructions explaining what the shareholder must do to effect the
            surrender of the E'town stock certificates in exchange for the
            merger consideration.

     After you submit your stock certificates, a letter of transmittal and other
documents that may be required, you will have the right to receive the merger
consideration represented by the surrendered shares.

     The merger consideration may be delivered to someone who is not listed in
E'town's transfer records if they present an E'town share certificate to the
paying agent along with all documents required to prove that the certificate has
been transferred to them and any applicable stock transfer taxes have been paid.

     Until surrendered, each certificate (other than those representing those
shares to be canceled which are held by E'town as treasury stock or by Thames)
will be deemed at any time after the Effective Time to represent only the right
to receive the merger consideration upon surrender. No interest will be paid on
any cash payable to those surrendering certificates.

     From and after the Effective Time, E'town's stock transfer books will be
closed and there will be no further registration of transfers of E'town shares
which were outstanding immediately prior to the Effective Time. Certificates
presented, for any reason, to Thames after the Effective Time will be canceled
and exchanged for the per share merger consideration.

  Lost, Stolen or Destroyed Certificates.

     If you are the registered holder of a certificate representing E'town
shares and the certificate has been lost, stolen or destroyed, you can receive
the merger consideration payable in exchange for those shares by delivering to
the paying agent an affidavit stating that the certificate has been lost, stolen
or destroyed. Before releasing the merger consideration, Thames may require you
to post a bond in a customary amount as indemnity against any claim that may be
made against Thames, E'town or the surviving company with respect to the missing
certificate.

  Withholding Rights.

     Thames and the surviving company are entitled to withhold from payments of
the merger consideration to you such amounts as are required to be deducted and
withheld by federal, state, local and foreign tax laws, including the tax laws
of the United Kingdom. If this withholding may be eliminated or reduced by the
delivery of any certificate or other documentation, Thames and the surviving
company will afford you a reasonable opportunity to provide that documentation.
For purposes of the Merger Agreement and the payment of the merger
consideration, any amounts withheld for these reasons will be treated as having
been paid to you.

     DO NOT FORWARD CERTIFICATES TO THE PAYING AGENT, THAMES OR E'TOWN UNTIL YOU
HAVE RECEIVED THE LETTER OF TRANSMITTAL. DO NOT RETURN CERTIFICATES WITH THE
ENCLOSED PROXY. THE LETTER OF TRANSMITTAL WILL BE MAILED TO YOU UNDER SEPARATE
COVER BEFORE THE CLOSING DATE, WHICH IS CURRENTLY EXPECTED TO OCCUR BEFORE THE
FOURTH QUARTER OF 2000.

       the following:

           (D) if the Effective Time does not occur between a record date and
               payment date of a regular quarterly dividend, E'town may declare
               and pay a special dividend, at the then current quarterly rate,

          stock);

        - adopt a plan of partial or complete liquidation or resolutions
          authorizing liquidation, dissolution, merger, consolidation,

          and practice;

     - maintain customary insurance;

     - not issue, deliver, sell, pledge, dispose of or otherwise encumber any

        - issuances by a subsidiary to E'town or to another subsidiary;

     - advise Thames of any change or event which has occurred which has had or
       could reasonably be expected to have a material adverse effect on E'town;

     - use commercially reasonable efforts to obtain all necessary consents to
       complete the merger, promptly notify Thames of any failure or likely

     - inform Thames in advance of making filings to implement any changes in

       base rates after that date only on certain conditions;

     - use reasonable efforts to maintain in effect all existing governmental
       permits under which they operate, except for those permits which, if they
       were lost, would not have a material adverse effect on the company;

  Covenants of Thames.

     Thames has agreed that it will cause Merger Sub not to do anything
inconsistent with the Merger Agreement. It has also agreed not to acquire any
other company or a substantial portion of its assets with material regulated
utility operations in the State of New Jersey if doing so would be likely to
endanger or delay the completion of the merger.

  No Solicitation of Alternative Proposals.

     E'town also agreed to certain restrictions concerning "Alternative
Proposals." An Alternative Proposal is defined in the Merger Agreement as a
merger, acquisition, consolidation, reorganization, share exchange,

                                       38
<PAGE>   45

tender offer, exchange offer or similar transaction involving E'town, or any
proposal or offer to acquire in any manner, directly or indirectly:

     - 50% or more of E'town common stock;

     - 50% or more of the outstanding common stock of Elizabethtown Water
       Company; or

     - all or substantially all of the assets of E'town and its subsidiaries
       taken as a whole.

  Specifically, E'town agreed that:

     - neither it nor its subsidiaries will encourage, initiate or solicit any
       inquiries, proposals or offers that constitute, or may reasonably be
       expected to lead to, an Alternative Proposal from any person or engage in
       any discussion or negotiations concerning, or provide any non-public
       information or data to make or implement an Alternative Proposal (and
       E'town will also prevent its officers, directors, employees, agents and
       representatives, as well as those of its subsidiaries, from doing any of
       those things);

     - it would immediately put an end to any solicitation, initiation,
       encouragement, activity, discussions or negotiations with any parties
       existing at the date of the Merger Agreement and conducted with a view of
       formulating an Alternative Proposal; and

     - it will immediately notify Thames if it receives any such inquiries,
       offers or proposals and it will keep Thames informed of their status, the
       identity of the person or group making it, and the material terms
       thereof.

     Nonetheless, E'town may take the following steps:

     - at any time before the E'town shareholders vote to approve the Merger
       Agreement, E'town may engage in discussions or negotiations with a third
       party that seeks to initiate such discussions or negotiations, and may
       furnish such third party with information concerning E'town and its
       business, properties and assets, but only if it complies with the
       following requirements:

          (i) the E'town board of directors:

           - concludes in good faith that the third party has made an
             Alternative Proposal that is reasonably likely to be a "Superior
             Proposal," i.e., an Alternative Proposal on terms which E'town's
             board of directors determines in good faith, based on the advice of
             its financial advisor, to be more favorable to the company's
             shareholders than the merger and for which adequate financing has
             been demonstrated to be available; and

           - concludes in good faith, based upon the advice of outside counsel
             and other relevant matters, that engaging in these discussions or
             negotiations with the third party is necessary for the E'town board
             of directors to act in a manner consistent with its fiduciary
             duties to shareholders under applicable law; and

          (ii) before E'town provides information to, or enters into discussions
     or negotiations with, the third party, E'town:

           - promptly notifies Thames that it intends to furnish information to,
             or intends to enter into discussions or negotiations with, that
             third party;

           - identifies the person or group making the Alternative Proposal and
             its material terms; and

           - receives from the third party an executed confidentiality agreement
             in reasonably customary form except that the confidentiality
             agreement with the third party shall not prohibit the third party
             from making an unsolicited Alternative Proposal to the board of
             directors of E'town;

     - E'town may state its position to its shareholders in respect of a tender
       or exchange offer in order to comply with Rule 14e-2 under the Securities
       Exchange Act of 1934, as amended, (the "Exchange Act"); or

                                       39
<PAGE>   46

     - E'town may accept an Alternative Proposal from a third party, provided
       that E'town's board of directors determines in good faith, after
       receiving advice from its financial advisor, that such Alternative
       Proposal is a Superior Proposal and provided also that it first
       terminates the Merger Agreement in accordance with its terms, including
       the payment of the termination fee described below.

ADDITIONAL AGREEMENTS

     In addition to the covenants above, the parties have also agreed on the
following matters:

  Access to Information.

     Until the Effective Time, upon reasonable notice and during normal business
hours, E'town will afford Thames reasonable access to all of its properties,
books, contracts, commitments and records. E'town will afford this access:

     - to the extent it is legally allowed to do so;

     - to the extent this access does not constitute a waiver of the
       attorney-client privilege;

     - to the extent it does not unreasonably interfere with E'town's business
       and operations; and

     - provided such right of access shall not include environmental inspections
       or testing with respect to the properties of E'town or its subsidiaries.

     In addition, E'town will provide to Thames:

     - a copy of each material report, schedule and other document that E'town
       or its subsidiaries filed or received under federal or state securities
       laws or filed with or sent to any regulatory agency or commission; and

     - access to all information concerning E'town and its subsidiaries as may
       be reasonably requested by Thames in connection with any filings,
       applications or approvals required under the Merger Agreement.

     Each party will hold in strict confidence, and will cause their
subsidiaries and representatives to hold in strict confidence, all information
furnished to it in connection with the merger.

  Regulatory Matters.

     E'town, Thames and Merger Sub will cooperate with each other and use their
best efforts to promptly prepare and file all necessary documentation, to effect
all necessary applications, notices, petitions, filings and other documents, and
to use all commercially reasonable efforts to obtain the required governmental
consents no later than August 21, 2000.

  Indemnification of Directors and Officers; Insurance

     See "The Merger -- Interests of Certain Persons in the
Merger -- Indemnification," at page 32.

  Public Announcements.

     Subject to their legal obligations to disclose information, E'town and
Thames will cooperate with each other in the development and distribution of all
news releases and other public information disclosures about the Merger
Agreement and the merger. In addition, they will not issue any public
announcement or statement concerning the merger without the consent (which
cannot be unreasonably withheld) of the other party.

  E'town Rights Agreement.

     E'town agreed to amend its Rights Agreement dated as of February 4, 1991
with the Bank of New York, as Rights Agent, so that (i) E'town can proceed to
consummate the merger without triggering the provisions of that agreement, and
(ii) the rights under that agreement expire immediately prior to the Effective
Time.
                                       40
<PAGE>   47

  Employee Agreements.

     Except as provided below, Thames and the surviving company and its
subsidiaries will honor, assume and perform, without modification, all existing
contracts, agreements, collective bargaining agreements and commitments of
E'town and its subsidiaries that were entered into before November 21, 1999 (or
entered into after that date and before the Effective Time, to the extent
permitted by the Merger Agreement), and apply to current or former employees and
directors of E'town and its subsidiaries.

     Thames or the surviving company may also enforce such employment agreements
in accordance with their terms, including any reserved rights of amendment,
modification, suspension, revocation or termination. The objective of Thames is
to create a working environment within the surviving company which will satisfy
the objectives of all the stakeholders of the surviving company.

  Employee Benefit Plans.

     Thames must, directly or indirectly, provide the following employee
benefits to those employees of E'town or its subsidiaries, who continue to be
employees of the surviving company, Thames or their respective subsidiaries:

     - for the 12 months immediately after the Closing Date, compensation,
       benefits and coverage that are no less favorable in the aggregate than
       those benefits provided immediately before the Closing Date (it being
       understood that, after the Closing Date, E'town common stock, or options
       to buy E'town stock, need not be issued under any employee benefit plans
       or arrangements);

     - the honoring of any employee benefit plan or arrangement which provided
       as of November 21, 1999 for a continuation period of longer than 12
       months;

     - for the 12 months immediately after the Closing Date, no termination of
       employment (other than voluntary retirement or voluntary termination by
       the employee) other than for cause;

     - full credit for years of service with E'town or its subsidiaries for the
       purposes of eligibility, vesting, benefit accrual and determination of
       the level of benefits under any pension plans of the surviving company in
       effect as of the Closing Date to the same extent recognized by E'town or
       its subsidiaries immediately prior to the Closing Date, provided that
       such credit does not result in duplication of benefits;

     - waiver of all limitations as to preexisting conditions, exclusions and
       waiting periods with respect to participation and coverage requirements
       under any welfare benefit plan established to replace any E'town welfare
       benefit plans after the Closing Date, other than limitations or waiting
       periods that are already in effect and that have not been satisfied by
       the Closing Date;

     - credit for any co-payments and deductibles paid prior to the Closing Date
       in satisfying any applicable deductible or out-of-pocket requirements
       under any welfare plans that are participated in after the Closing Date;
       and

     - for a period of not less than 12 months immediately after the Closing
       Date, retiree medical plan coverage not less favorable than provided by
       E'town as of November 21, 1999 (i) to former employees (as of that date)
       receiving such benefits as of that date, and (ii) to those persons
       employed as of November 21, 1999 who retire prior to the Closing Date.

  Expenses.

     Except as described under "Termination, Amendment, and Waiver" below,
E'town and Thames will pay their own costs and expenses incurred in connection
with the merger.

                                       41
<PAGE>   48

  Further Assurances.

     Each party and its subsidiaries will execute additional documents if
necessary, and do everything that another party may reasonably request in order
to complete the merger in accordance with the Merger Agreement.

  Community Involvement.

     Thames will cause the surviving company to make charitable contributions to
the communities served by it and otherwise maintain a level of involvement in
community activities in New Jersey consistent with the level of community
activities customarily carried on by Thames's other regulated utility
subsidiaries.

  Transition Planning.

     E'town and Thames will set up a committee responsible for coordinating
transition planning and implementation relating to the merger. The initial
members of the committee will be Michael Carmedy and Debbie Wrench (from Thames)
and Andrew M. Chapman and Edward A. Clerico (from E'town). Prior to the
Effective Time, Thames may locate up to two representatives at the offices of
E'town (who shall not interfere with, or have any authority over, the business
and operations of E'town or its subsidiaries) and at least one E'town
representative will be designated to consult with these Thames representatives
to discuss the general status of E'town's business.

  Compliance with ISRA.

     Prior to the Closing Date, E'town will take all actions necessary to
complete the merger in compliance with ISRA. E'town will not, however, be
required to execute a Remediation Agreement (as defined in ISRA) with the NJDEP
which, in E'town's reasonable judgment, could be expected to have a material
adverse effect on the company, unless that Remediation Agreement would be
binding on E'town only if the merger is completed.

  E'town Convertible Subordinated Debentures.

     At the written request of Thames after (i) the approval of the BPU for the
merger has been obtained, (ii) compliance with ISRA has been achieved and (iii)
the statutory approvals required to complete the merger have been obtained on
terms which would not, in the reasonable judgment of Thames, be expected to have
a material adverse effect on the surviving company and its subsidiaries taken as
a whole if the merger were completed, E'town will call for redemption, at the
earliest permitted time, all of its convertible subordinated debentures which
are then outstanding. If redemption has not occurred prior to the Effective
Time, Thames will assume the obligation to deliver, after the Effective Time,
the merger consideration upon conversion of the convertible subordinated
debentures then outstanding. This will not affect the price per share of E'town
common stock to be paid to E'town shareholders in connection with the merger. If
the convertible subordinated debentures have not been redeemed by the Effective
Time, the merger will not, of itself, trigger their conversion.

  Stock Options and Restricted Stock.

     At the Effective Time, the options under E'town's 1987 and 1998 Stock
Option Plans which are vested and outstanding immediately before the Effective
Time will be canceled. The optionholders will have the right to receive (x)
$68.00 for each share they would have received had they exercised all their
options immediately before the Effective Time, less (y) the aggregate exercise
price for those shares and any required withholding taxes. Prior to the
Effective Time, E'town is permitted to take action to cause the vesting of
unvested options under these plans. This will not affect the price per share of
E'town common stock to be paid to E'town shareholders in connection with the
merger.

     Before the Closing Date, E'town may take all actions necessary to cancel
and eliminate all restrictions and vesting provisions applicable to the
restricted stock awards granted prior to November 21, 1999 under

                                       42
<PAGE>   49

E'town's 1990 Performance Stock Program, Management Incentive Plan and 1998
Directors' Stock Plan, so that the holders of that restricted stock may exchange
it for the merger consideration. This will not affect the price per share of
E'town common stock to be paid to E'town shareholders in connection with the
merger.

     E'town will not permit any additional options to purchase E'town common
stock or grants of restricted E'town common stock to be issued or granted under
E'town's stock option plans, performance stock plans, management incentive
plans, directors' stock plans or otherwise.

CONDITIONS

  Mutual Conditions.

     Before either E'town or Thames will be obliged to complete the merger, the
following conditions must have been met or waived:

     - E'town shareholders must have approved the Merger Agreement;

     - Any waiting period applicable to the merger under the Hart-Scott Act must
       have expired or been terminated;

     - No federal or state law or regulation, and no restraints issued by any
       federal or state court, remain in effect which would prohibit completion
       of the merger;

     - E'town and Thames must have obtained the necessary governmental approvals
       (including the approval of the New Jersey Board of Public Utilities) by
       the Effective Time and all applicable waiting periods must have expired;

     - Compliance of the merger with ISRA shall have been achieved.

  Conditions to Obligations of Thames.

     Before Thames and Merger Sub will be obliged to complete the merger, the
following conditions must have been met, or waived by Thames:

     - E'town must have performed in all material respects the agreements and
       covenants required by the Merger Agreement;

     - The representations and warranties of E'town in the Merger Agreement must
       be true on the Closing Date, unless the representation and warranty
       speaks of a specified date. In that case, the representation and warranty
       must be true on the date specified. The representations and warranties
       may contain inaccuracies if they would not reasonably be expected to have
       a material adverse effect on E'town;

       Date and signed by E'town's President stating that the above two

       disclosed in the schedules to the Merger Agreement or in E'town's filings
       with the Securities and Exchange Commission (the "SEC") filed before

       disclosed in those schedules and those SEC filings, that is reasonably
       likely to have a material adverse effect on E'town;

     - The statutory approvals required to complete the merger shall not impose
       terms which, in the reasonable judgment of Thames, could be expected to
       have a material adverse effect on the business, properties, financial
       condition or results of operations of the surviving corporation and its
       subsidiaries taken as a whole, if the merger were completed; and

     - E'town must have obtained the necessary third party consents, unless the
       failure to obtain those consents would not have a material adverse effect
       on E'town.

                                       43

  Conditions to Obligations of E'town.

     Before E'town is obliged to complete the merger, the following conditions
must have been met, or waived by E'town:

     - Thames must have performed in all material respects the agreements and
       covenants required by the Merger Agreement;

     - The representations and warranties of Thames in the Merger Agreement must
       be true on the Closing Date, unless the representation and warranty
       speaks of a specified date. In that case, the representation and warranty
       must be true on the date specified. The representations and warranties
       may contain inaccuracies if they would not reasonably be expected to have
       a material adverse effect on Thames; and

     - Thames must have provided E'town with a certificate, dated the Closing
       Date and signed by the Chief Executive Officer of Thames stating that the
       above two conditions have been satisfied.

TERMINATION, AMENDMENT AND WAIVER

  Termination.

     The Merger Agreement may be terminated and the other transactions
contemplated in the Merger Agreement may be abandoned at any time before the
Effective Time, regardless of approval by the shareholders of E'town:

     - by mutual written consent of the boards of directors of E'town and
       Thames;

     - by either E'town or Thames, if the Effective Time has not occurred on or
       before August 21, 2000 (the "Initial Termination Date") so long as the
       party seeking termination has not caused the delay by failing to fulfill
       its obligations under the Merger Agreement. However, if certain
       governmental, regulatory and other consents and approvals have not yet
       been obtained by the Initial Termination Date, but all other conditions
       to the closing of the merger were fulfilled by then, the Initial
       Termination Date shall be extended to November 21, 2000 (the "Extended
       Termination Date"). If on the Extended Termination Date, the periods
       prescribed by law for appeal or rehearing of these consents or approvals
       have not expired, the Extended Termination Date will be extended to the
       date on which these periods expire;

     - by either E'town or Thames, if the E'town shareholders have not approved
       the Merger Agreement at the Special Meeting or any adjournments of the
       Special Meeting;

     - by either E'town or Thames, if any law prohibits the merger (this
       determination must be supported by the written opinion of outside
       counsel) or if any court of competent jurisdiction issues a final and
       nonappealable decision that permanently prohibits the merger from being
       completed. E'town or Thames may not seek termination, however, if they
       have not defended the lawsuit or proceeding which prohibits the merger;

     - by E'town, if:

        - its board of directors determines in good faith, based on the advice
          of outside counsel, that termination of the Merger Agreement is
          necessary for it to act in a manner consistent with its fiduciary
          duties to shareholders under applicable law in order to enter into an
          agreement with respect to, or to consummate a transaction
          constituting, a Superior Proposal (see page 39, above, for the
          definition of "Superior Proposal");

        - it first gives notice to Thames of its receipt of the Superior
          Proposal, the material terms of that proposal (including the identity
          of the third party), and its intention to terminate the Merger
          Agreement;

        - either (A) Thames has not revised its proposal for the merger within
          10 days or (B) Thames has revised its proposal but E'town's board,
          after receiving advice from its financial advisor,

                                       44
<PAGE>   51

          determines in good faith that the third party's proposal is superior
          to the revised proposal from Thames; and

        - it pays the termination fees described below;

     - by either party, if there has been any material breach of any
       representation or warranty, covenant or agreement of the other party, and
       this breach has not been remedied within 20 days of receiving written
       notice of the breach;

     - by Thames, if the E'town board of directors:

        - withdraws or modifies its approval or recommendation of the merger in
          any manner adverse to Thames or Merger Sub;

        - approves or recommends an Alternative Proposal; or

        - resolves to take any of these actions.

  Effect of Termination.

     E'town and Thames have agreed that, if either of them terminates the Merger
Agreement for any reason outlined above, the Merger Agreement will become null
and void, without any liability on the part of Thames or E'town or their
officers or directors. Even in this case, however, the provisions in the Merger
Agreement concerning expenses, termination fees, the confidentiality agreement
between E'town and Thames, submission to jurisdiction, waiver of jury trial and
enforcement of the Merger Agreement will remain in effect.

  Termination Fees.

     If the Merger Agreement is terminated because of a material breach by
Thames or E'town of their representations, warranties, agreements or covenants,
the breaching party will pay up to $5 million cash to the other party for
reimbursement of all documented out-of-pocket expenses and fees incurred by the
other party. This amount is not a limit on the right of either party to sue for
additional damages in the event of a willful breach.

     E'town will pay Thames a termination fee of $16.5 million plus up to $5
million for reimbursement of documented out-of-pocket expenses:

     - if E'town's board of directors determines in good faith based upon the
       advice of outside counsel that it is necessary, in order to act
       consistently with its fiduciary duties to shareholders, to terminate the
       Merger Agreement in order to pursue a third party Superior Proposal;

     - if at a time when an Alternative Proposal is pending, the Merger
       Agreement is terminated:

        (i)  by Thames or E'town because E'town's shareholders approval is not
obtained;

        (ii)  by Thames because the E'town board of directors withdrew or
              modified its approval or recommendation of the Merger Agreement or
              approved or recommended an Alternative Proposal; or

        (iii) by E'town because the Effective Time did not occur by the Initial
              Termination Date (August 21, 2000) or, if applicable, the Extended
              Termination Date (November 21, 2000, or until the expiration of
              certain prescribed waiting periods);

             and, in the case of (i), (ii) and (iii) above, E'town enters into a
             definitive agreement with the party making the Alternative Proposal
             within one year of termination of the Merger Agreement.

  Amendment.

     The Merger Agreement may be amended at any time before or after E'town's
shareholders have voted to approve it and prior to the Effective Time.
Amendments made after such shareholder approval can only be
                                       45
<PAGE>   52

made to the extent permitted by applicable law. Amendments to the Merger
Agreement must be in writing signed by each of the parties.

  Waiver.

     At any time before the Effective Time, the parties may, to the extent
permitted by law:

     - extend the time for the performance of any of the obligations under the
       Merger Agreement;

     - waive any inaccuracies in the representations and warranties; and

     - waive compliance with any of the agreements or conditions in the Merger
       Agreement.

     The agreement of a party to any such extension or waiver is only valid if
it is in writing and is signed on behalf of that party.

     To the extent required by New Jersey law, E'town would resolicit
shareholder votes, including by circulation of a revised proxy statement (or
supplement to the proxy statement), in the event of a material amendment to the
Merger Agreement prior to or after shareholder approval or in the event that a
material condition to the merger was waived prior to or after shareholder
approval.

          SHARE OWNERSHIP OF MANAGEMENT AND CERTAIN BENEFICIAL OWNERS

     As of March 30, 2000, there were outstanding 8,774,898 shares of E'town's
common stock, the only capital stock entitled to vote at the Special Meeting.
Each share of common stock is entitled to one vote. As stated in the Notice of
Special Meeting, only holders of record of the common stock at the close of
business on that date will be entitled to vote at the meeting or any adjournment
thereof.

     Under current rules of the SEC, a person who directly or indirectly has or
shares voting power and/or investment power with respect to a security is
considered a beneficial owner of the security. Voting power is the power to vote
or direct the vote of shares, and investment power is the power to dispose of or
direct the disposition of shares.

     The following information pertains to the common stock of E'town that, to
the knowledge of the company, is beneficially owned, directly or indirectly,
individually and as a group, by all directors (including nominees) and executive
officers of E'town and its subsidiary, Elizabethtown Water Company, as of March
30, 2000, on which date there were 8,774,898 shares of common stock outstanding.
No shareholder has reported beneficial ownership of 5% or more of the
outstanding common stock.

shareholders in attendance.

                                 OTHER MATTERS

     Pursuant to New Jersey law, the business that may be conducted at the
Special Meeting is confined to the purpose described in the Notice of Special
Meeting of Shareholders that accompanies this proxy statement.

                             SHAREHOLDER PROPOSALS

     If the annual meeting of E'town's shareholders for the Year 2000 (the "Year
2000 Annual Meeting") is to be held prior to the consummation of the merger, any
proposal that you intend to present at the Year 2000 Annual Meeting must be
received by the Secretary of E'town (at 600 South Avenue, Westfield, New Jersey
07090) by no later than October 1, 2000 in order to be included in the proxy
statement and form of proxy relating to that meeting. Under the rules of the
SEC, in order to be eligible to submit a proposal, you must have continuously
held at least $2,000 in market value, or 1%, of E'town's common stock for at
least one year by the date you submit the proposal, and you must continue to
hold such common stock through the date of the meeting.

                     CERTAIN VOTING AND PROXY CARD MATTERS

     If you participate in the E'town Dividend Reinvestment and Stock Purchase
Plan, your proxy card represents both the number of E'town shares registered in
your name and the number of shares credited to your account, unless the
registrations are in different names. If you have shares registered in different
names you will receive a separate proxy card for each registration. If you hold
shares under the 401(k) Plan, you will receive a separate proxy card for those
shares. If your shares are held by a broker as nominee, you will receive a voter
information form from your broker. All these shares will be voted in accordance
with the instructions you submit on your proxy card.

     Votes submitted via the Internet or by telephone must be received by 6:00
p.m. (New York City time), on May 17, 2000. Submitting your proxy via the
Internet or by telephone will not affect your right to vote in person should you
decide to attend the Special Meeting. (Remember, however, that you may not vote
shares held through the 401(k) Plan either by telephone or via the Internet. You
must return the separate proxy card issued in respect of these shares to
Corporate Election Services by no later than May 16, 2000.)

     The telephone and Internet voting procedures are designed to authenticate
your identity, to allow you to give your voting instructions and to confirm that
your instructions have been recorded properly. If you are voting via the
Internet you should understand that there may be costs associated with
electronic access, such as usage charges from Internet access providers and
telephone companies, that must be borne by you.

                                   ARTICLE II

                              TREATMENT OF SHARES

     Section 2.01 Effect of the Merger on Capital Stock.  At the Effective Time,
by virtue of the Merger and without any action on the part of any holder of any
capital stock of the Company or Parent:

          (a) Shares of Merger Sub Stock.  Each share of common stock, no par
     value, of Merger Sub (the "Merger Sub Common Stock") that is issued and
     outstanding immediately prior to the Effective Time shall be converted into
     one fully paid and nonassessable share of common stock, without par value,
     of the Surviving Corporation.

          (b) Cancellation of Certain Company Common Stock.  Each share of
     common stock, no par value, of the Company (the "Company Common Stock")
     that is owned by the Company as treasury stock and all shares of Company
     Common Stock that are owned by Parent (if any) shall be canceled and shall
     cease to exist, and no cash or other consideration shall be delivered in
     exchange therefor.

          (c) Conversion of Company Common Stock.  Each share of Company Common
     Stock issued and outstanding immediately prior to the Effective Time (other
     than shares to be canceled in accordance with Section 2.01(b)) shall be
     canceled and converted in accordance with the provisions of this Section
     2.01 into the right to receive cash in U.S. dollars in the amount of $68.00
     (the "Merger Consideration"), payable, without interest, to the holder of
     such share of Company Common Stock, upon surrender, in the manner provided
     in Section 2.02 hereof, of the certificate formerly evidencing such share.

     Section 2.02 Surrender of Shares.  (a) Deposit with Paying Agent.  Prior to
the Effective Time, Parent or Merger Sub shall designate a bank or trust company
reasonably acceptable to the Company to act as agent (the "Paying Agent") for
the benefit of the holders of Company Common Stock to receive the funds to which
holders of Company Common Stock shall become entitled pursuant to Section
2.01(c) (the "Exchange Fund"). From time to time at, immediately prior to or
after the Effective Time, Parent shall make or cause to be made available to the
Paying Agent immediately available funds in amounts and at the times necessary
for the payment of the Merger Consideration upon surrender of Certificates (as
defined in Section 2.02(b)) in accordance with Section 2.02(b), it being
understood that any and all interest or other income earned on funds made
available to the Paying Agent pursuant to this Section 2.02(a) shall belong to
and shall be paid (at the time provided for in Section 2.02(e)) as directed by
Parent or Merger Sub. Any such funds deposited with the Paying Agent by Parent
shall be invested by the Paying Agent as directed by Parent or Merger Sub.

     (b) Exchange Procedure.  As soon as practicable after the Effective Time,
the Paying Agent shall mail to each holder of record of a certificate or
certificates (the "Certificates") which immediately prior to the Effective Time
represented outstanding Company Common Stock (the "Canceled Shares") that were
canceled and became instead the right to receive the Merger Consideration
pursuant to Section 2.01(c): (i) a letter of transmittal in such form as Parent
and the Company may reasonably agree (which shall specify that delivery shall be
effected, and risk of loss and title to the Certificates shall pass, only upon
actual delivery of the Certificates to the Paying Agent) and (ii) instructions
for effecting the surrender of the Certificates in exchange for the Merger
Consideration. Upon surrender of a Certificate or Certificates to the Paying
Agent for cancellation (or to such other agent or agents as may be appointed by
Parent and are reasonably acceptable to the Company), together with a duly
executed letter of transmittal and such other documents as the Paying Agent
shall require, the holder of such Certificate shall be entitled to receive the
Merger Consideration in exchange for each share of Company Common Stock formerly
evidenced by such Certificate which such holder has the right to receive
pursuant to Section 2.01(c). In the event of a transfer of ownership of Canceled

                                        2
<PAGE>   65

Shares which is not registered in the transfer records of the Company, the
Merger Consideration in respect of such Canceled Shares may be given to the
transferee thereof if the Certificate or Certificates representing such Canceled
Shares is presented to the Paying Agent, accompanied by all documents required
to evidence and effect such transfer and by evidence satisfactory to the Paying
Agent that any applicable stock transfer taxes have been paid. At any time after
the Effective Time, each Certificate shall be deemed to represent only the right
to receive the Merger Consideration subject to and upon the surrender of such
Certificate as contemplated by this Section 2.02. No interest shall be paid or
will accrue on the Merger Consideration payable to holders of Certificates
pursuant to Section 2.01(c).

     (c) No Further Ownership Rights in Company Common Stock.  The Merger
Consideration paid upon the surrender of Certificates in accordance with the
terms of Section 2.01(c) shall be deemed to have been paid at the Effective Time
in full satisfaction of all rights pertaining to the shares of Company Common
Stock represented thereby. From and after the Effective Time, the share transfer
books of the Company shall be closed and there shall be no further registration
of transfers thereon of the shares of Company Common Stock which were
outstanding immediately prior to the Effective Time. If, after the Effective
Time, Certificates are presented to Parent for any reason, they shall be
canceled and exchanged as provided in this Section 2.02.

     (d) Lost, Stolen or Destroyed Certificates.  In the event any owner of any
Certificate shall claim that such Certificate shall have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the owner of such
Certificate and delivery of that affidavit to the Paying Agent and, if required
by Parent, the posting by such person of a bond in customary amount as indemnity
against any claim that may be made against Parent, the Company or the Surviving
Corporation with respect to such Certificate, the Paying Agent will issue in
exchange for such lost, stolen or destroyed Certificate the Merger Consideration
payable upon due surrender of, and deliverable pursuant to this Section 2.02 in
respect of, the shares of Company Common Stock to which such Certificate
relates.

     (e) Termination of Exchange Fund.  Any portion of the Exchange Fund which
remains undistributed to the shareholders of the Company for one year after the
Effective Time shall be delivered to the Surviving Corporation upon demand, and
any shareholders of the Company who have not theretofore complied with this
Article II shall thereafter look only to the Surviving Corporation (subject to
abandoned property, escheat and other similar laws) as general creditors for
payment of their claim for the Merger Consideration payable upon due surrender
of the Certificates held by them. Neither Parent nor the Surviving Corporation
shall be liable to any former holder of shares of Company Common Stock for the
Merger Consideration delivered to a public official pursuant to any applicable
abandoned property, escheat or similar law.

     Section 2.03 Withholding Rights.  Each of the Surviving Corporation and
Parent shall be entitled to deduct and withhold from the consideration otherwise
payable pursuant to this Agreement to any holder of Company Common Stock, such
amounts as it is required to deduct and withhold with respect to the making of
such payment under the Internal Revenue Code of 1986, as amended (the "Code"),
or any provision of state, local or foreign tax law, including the tax laws of
the United Kingdom; provided, however, that if such withholding may be
eliminated or reduced through the delivery of any certificate or other
documentation, each of the Surviving Corporation and the Parent shall provide
each holder of Company Common Stock with a reasonable opportunity to deliver
such certificate or other documentation. To the extent that amounts are so
withheld by the Surviving Corporation or Parent, as the case may be, such
withheld amounts shall be treated for all purposes of this Agreement as having
been paid to the holder of Company Common Stock in respect of which such
deduction and withholding was made by the Surviving Corporation or Parent, as
the case may be.

                                  ARTICLE III

following the date on which the last of the conditions set forth in Article VIII

                                        3
<PAGE>   66

performed on the Closing Date, but subject to satisfaction of such conditions),
or at such other time and date and place as the Company and Parent shall
mutually agree (the "Closing Date").

adverse effect being hereafter referred to as a "Company Material Adverse
Effect"). As used in this Agreement, the term "subsidiary" of a person shall

free and clear of any liens, claims, encumbrances, security interests, equities,
charges and options of any nature whatsoever, and there are no outstanding
subscriptions, options, calls, contracts, voting trusts, proxies, rights or
warrants, including any right of conversion or exchange under any outstanding
security, instrument or other agreement, obligating any such subsidiary to

shares of its capital stock or obligating it to grant, extend or enter into any
such agreement or commitment.

Material Adverse Effect (the "Company Required Statutory Approvals").

written agreement relating to employment or fringe benefits for employees,
leased employees, former employees, officers or directors of the Company or any

date hereof to Company Personnel or pursuant to which the Company or any of its
subsidiaries has or could reasonably be expected to have any liability
(collectively, the "Company Employee Benefit Plans") is listed in Schedule
4.10(a) of the Company Disclosure Schedule. Each Company Employee Benefit Plan
is in material compliance with applicable law, and has been administered and
operated in all material respects in accordance with its terms. Each Company
Employee Benefit Plan which is intended to be qualified within the meaning of
Section 401(a) of the Code has received a favorable determination letter from
the IRS as to such qualification and, to the knowledge of the Company, no event
has occurred and no condition exists which could reasonably be expected to
result in the revocation of any such determination.

     (b) Complete and correct copies of the following documents have been made
available to Parent as of the date of this Agreement: (i) all Company Employee
Benefit Plans (or in each case of an unwritten plan, a written description
thereof) and any related trust agreements or insurance contracts, (ii) the most

Schedule, none of the Company, any of its subsidiaries or any other entity
required to be aggregated with the Company or any of its subsidiaries under
Section 4.14(b) or (c) of the Code (the "Controlled Group") has, within the
five-year period preceding the date of this Agreement, at any time contributed
to any "multiemployer plan," as that term is defined in Section 4001 of ERISA.

     (d) Except as disclosed on Section 4.10(d) of the Company Disclosure

Plan. No event has

                                        8
<PAGE>   71

occurred, and to the knowledge of the Company there exists no condition or set
of circumstances in connection with any Company Employee Benefit Plan, under
which the Company or any subsidiary, directly or indirectly (through any
indemnification agreement or otherwise), could be subject to any liability under

Effect.

Controlled Group has incurred any liability to the Pension Benefit Guaranty
Corporation (the "PBGC") or otherwise under Title IV of ERISA (other than the
payment of premiums none of which are overdue) that has not been satisfied in
full and no event or condition exists or has existed which could reasonably be
expected to result in any such material liability. As of the date of this
Agreement, no "reportable event" within the meaning of Section 4043 of ERISA has
occurred with respect to any Company Employee Benefit Plan that is a defined
benefit plan under Section 3(35) of ERISA.

     (f) Full payment has been made of all material amounts which the Company or
any affiliate thereof was required under the terms of Company Employee Benefit
Plans to have paid as contributions to such plans with respect to periods prior
to the date hereof (excluding any amounts not yet due) or there has been an
accrual on the books and records of the Company with respect to any such amounts
and none of the Company, any of its subsidiaries or any member of the Controlled
Group (including for this purpose any entities required to be aggregated under
Section 414(m) or (o) of the Code) has incurred or reasonably expects to incur
any "accumulated funding deficiency" within the meaning of Section 302 of ERISA

Benefit Plans (or their trusts), the Company, any of its subsidiaries or any
other person who the Company or any of its subsidiaries has an obligation to
indemnify, to any material tax or penalty imposed under Section 4975 of the Code
or Section 502 of ERISA.

pay, unemployment compensation, or other similar payments under any Company
Employee Benefit Plan, (x) accelerate the time of payment or vesting or increase
the amount of benefits due under any Company Employee Benefit Plan or
compensation to any Company Personnel, (y) result in any payments (including

unions to which the Company or any of its subsidiaries is a party are described

such Section 4.10(j), no labor organization or group of employees of the Company
or any of its subsidiaries has made a pending demand for recognition or
certification, and there are no representation or certification proceedings or
petitions seeking a representation proceeding presently pending or, to the
knowledge of the Company, threatened to be brought or filed, with the National
Labor Relations Board or any other labor relations tribunal or authority. Except
as set forth in Schedule 4.10(j) of the Company Disclosure Schedule, there are
no organizing activities, strikes, work stoppages, slowdowns, lockouts,
arbitrations or grievances, or other labor disputes pending or, to the knowledge
of the Company, threatened against or involving the Company or any of its
subsidiaries which could reasonably be expected to have a Company Material
Adverse Effect. Each of the Company and its subsidiaries is in compliance with
all applicable laws and collective bargaining agreements respecting employment
and employment practices, terms and conditions

                                        9

     and all such Environmental Permits are in good standing or, where
     applicable and as described in Section 4.11(b) of the Company Disclosure
     Schedule, a renewal application has been timely filed and is pending agency
     approval, and the Company and its subsidiaries are in compliance with all
     terms and conditions of the Environmental Permits, except where the failure

     in Section 4.11(g)(i)) pending (i) against the Company or any of its
     subsidiaries, or (ii) against any real or personal property or operations

     Claim pending or threatened, or of any Release of Hazardous Materials that
     would be reasonably likely to form the basis of any Environmental Claim, in
     each case against any person or entity (including, without limitation, any
     predecessor of the Company or any of its subsidiaries) whose liability the
     Company or any of its subsidiaries has or may have retained or assumed
     either contractually or by operation of law, except for Releases of

2000 (the operations of clauses (i), (ii) and (iii) together, "Millennium

Millennium Functionality.

interest in any such property is subject to any mortgage, pledge, lien, option,
conditional sale agreement, encumbrance, security interest, title exception or
restriction or claim or charge of any kind (collectively, "Liens"), except for
such Liens that would not, individually or in the aggregate, reasonably be
expected to have a Company Material Adverse Effect. Except as set forth on
Section 4.18(a) of the Company Disclosure Schedule, all such property is in good
condition and repair and is suitable in all material respects for the purposes
for which it is now being used in the conduct of the businesses of the Company
and its subsidiaries, except to the extent that the poor condition or
unsuitability of any such property would not, individually or in the aggregate,
reasonably be expected to have a Company Material Adverse Effect.

     (b) Personal Property.  Except as otherwise disclosed in the Company SEC
Reports or Section 4.18(b) of the Company Disclosure Schedule, all personal
property that is owned by the Company or any of its subsidiaries and used by any
of them in the conduct of their respective businesses is owned free and clear of
any Liens, except for such Liens that would not, individually or in the
aggregate, reasonably be expected to have a Company Material Adverse Effect.
Except as set forth on Section 4.18(b) of the Company Disclosure Schedule, all
such property is in good working condition, subject to normal wear and tear, and
is suitable in all material respects for the purposes for which it is now being

property would not, individually or in the aggregate, reasonably be expected to
have a Company Material Adverse Effect.

business in each jurisdiction in which the nature of its business or the
ownership or leasing of its assets and properties makes such qualification
necessary, other than in such jurisdictions where the failure to be so qualified
and in good standing would not, when taken together with all other such
failures, reasonably be expected to have a material adverse effect on the
business, properties, financial condition or results of operations of Parent and
its subsidiaries taken as a whole or on the ability of Parent and Merger Sub to
consummate this Agreement (any such material adverse effect being hereafter
referred to as a "Parent Material Adverse Effect"). Parent has previously

Parent and Merger Sub and, assuming the due authorization, execution and
delivery by the Company, constitutes a valid and binding obligation of each of
Parent and Merger Sub enforceable against each of them in accordance with its
terms.

     (b) Non-Contravention.  The execution and delivery of this Agreement by
Parent do not, and the consummation of the transactions contemplated hereby will
not, result in a Violation pursuant to any provisions of (i) the memorandum and
articles of association or other comparable charter documents of Parent or any
of its subsidiaries that would be considered "significant subsidiaries" as
defined in Rule 1-02(w) of Regulation S-X under the Exchange Act ("Parent
Subsidiaries"), (ii) subject to obtaining the Parent Required Statutory
Approval, any statute, law, ordinance, rule, regulation, judgment, decree,

franchise, permit, concession, contract, lease or other instrument, obligation
or agreement of any kind to which Parent or any Parent Subsidiaries is a party
or by which it or any of its properties or assets may be bound or affected,
excluding from the foregoing clauses (i), (ii) and (iii) such Violations as
would not reasonably be expected to have, in the aggregate, a Parent Material
Adverse Effect.

     (c) Statutory Approval.  Except for Hart-Scott-Rodino Anitrust Improvements
Act clearance (the "Parent Required Statutory Approval"), and, to the extent
required, filings or notices by Parent in respect of the application for
approval of the Merger by the New Jersey Board of Public Utilities, no
declaration, filing or registration with, or notice to or authorization, consent
or approval of, any Governmental Authority is necessary for the execution and
delivery of this Agreement by Parent and Merger Sub or the consummation by
Parent and Merger Sub of the transactions contemplated hereby, the failure to
obtain, make or give which would reasonably be expected to have, in the
aggregate, a Parent Material Adverse Effect.

     (d) Compliance.  Neither Parent nor any Parent Subsidiaries is in violation
of, or has been given notice of any purported violation of, any law, statute, or
order, rule, regulation or judgment (including, without limitation, any
applicable Environmental Law) of any Governmental Authority, except for

Material Adverse Effect. Parent and the Parent Subsidiaries have all permits,
licenses, franchises and other governmental authorizations, consents and
approvals necessary to conduct their respective businesses as currently

the aggregate, not reasonably be expected to have a Parent Material Adverse
Effect. Parent and the Parent Subsidiaries are not in breach or violation of or
in default in the performance or observance of any term or provision of, and no
event has occurred which, with lapse of time or action by a third party, could
result in a default under (i) its memorandum and articles of association or

agreement, indenture, mortgage, loan agreement, note, lease, bond, license,
approval or other instrument to which it is a party or by which it is bound or

defaults that, in the aggregate, are not reasonably expected to have a Parent

     or be subject to or bound by any obligation or undertaking, which is
     inconsistent with this Agreement.

          (u) Certain Mergers and Other Actions by Parent.  Parent shall not,
     and shall not permit any of its subsidiaries to, acquire or agree to
     acquire by merging or consolidating with, or by purchasing a substantial
     portion of the assets of or equity in, any business or any corporation,
     partnership or other business organization with material regulated utility
     operations in the State of New Jersey, if the entering into of a definitive
     agreement relating to or the consummation of such acquisition, merger or
     consolidation could reasonably be expected to (i) impose any material delay
     in the obtaining of, or significantly increase the risk of not obtaining,
     any authorizations, consents, orders, declarations or approvals of any
     Governmental Authority necessary to consummate the Merger or the expiration
     or termination of any applicable waiting period, (ii) significantly
     increase the risk of any Governmental Authority entering an order
     prohibiting the consummation of the Merger, (iii) significantly increase

     or (iv) materially delay the consummation of the Merger.

     Section 6.02 Covenant of the Company; Alternative Proposals.  (a) From and
after the date hereof, the Company agrees (i) that it and its subsidiaries will
not, and it will cause its and its subsidiaries' officers, directors, employees,
agents and representatives (including, without limitation, any investment
banker, attorney or accountant retained by it or any of its subsidiaries) not
to, directly or indirectly, encourage, initiate or solicit (including by way of
furnishing information) any inquiries or the making of any proposal or offer
(including, without limitation, any proposal or offer to its shareholders) which
constitutes or may reasonably be expected to lead to an Alternative Proposal (as
defined below) from any person or engage in any discussion or negotiations
concerning, or provide any non-public information or data to make or implement
an Alternative Proposal; (ii) that it will immediately cease and cause to be
terminated any existing solicitation, initiation, encouragement, activity,
discussions or negotiations with any parties conducted heretofore with a view of
formulating an Alternative Proposal; and (iii) that it will immediately notify
Parent orally and in writing of the receipt of any such inquiry, offer or
proposals, and that it shall keep Parent informed of the status of any such
inquiry, offer or proposal, the identity of the person or group making it, and
the material terms thereof.

     (b) Notwithstanding any other provision hereof, the Company may at any time
prior to the time the Company shareholders shall have voted to approve this
Agreement (i) engage in discussions or negotiations with a third party who,
without solicitation in violation of the terms hereof, seeks to initiate such
discussions or negotiations and may furnish such third party information
concerning the Company and its business, properties and assets if, and only to
the extent that, (A)(x) the third party has first made an Alternative Proposal
that, in the good faith judgment of the Company's Board of Directors, is
reasonably likely to result in a Superior Proposal (as defined below) and (y)
the Company's Board of Directors shall conclude in good

                                       18
<PAGE>   81

faith, based upon the advice of outside counsel and such other matters as the
Company's Board of Directors deems relevant, that such actions are necessary for
the Company's Board of Directors to act in a manner consistent with its
fiduciary duties to shareholders under applicable law, and (B) prior to
furnishing such information to, or entering into discussions or negotiations
with, such person or entity, the Company (x) provides prompt written notice to
Parent to the effect that it intends to furnish information to, or intends to
enter into discussions or negotiations with, such person or entity, and of the
identity of the person or group making the Alternative Proposal and the material
terms thereof and (y) receives from such person an executed confidentiality
agreement in reasonably customary form except that such confidentiality
agreement shall not prohibit such person from making an unsolicited Alternative
Proposal, (ii) comply with Rule 14e-2 promulgated under the Exchange Act with
regard to a tender or exchange offer and/or (iii) accept an Alternative Proposal
from a third party, provided that the Company's Board of Directors determines in
good faith, after receiving advice from its financial advisor, that such
Alternative Proposal is a Superior Proposal and provided further that the
Company has complied with the conditions for the termination of this Agreement
set forth in Section 9.01(e). "Alternative Proposal" shall mean any merger,
acquisition, consolidation, reorganization, share exchange, tender offer,
exchange offer or similar transaction involving the Company or any proposal or
offer to acquire in any manner, directly or indirectly (x) 50% or more of the
outstanding Company Common Stock, (y) 50% or more of the outstanding common
stock of Elizabethtown Water Company, or (z) all or substantially all of the
assets of the Company and its subsidiaries taken as a whole. Nothing herein
shall prohibit a disposition permitted by Section 6.01(g) hereof. "Superior
Proposal" shall mean an Alternative Proposal on terms which the Company's Board
of Directors determines in good faith, based on advice of its financial advisor,
to be more favorable to the Company's shareholders than the Merger and for which
adequate financing, to the extent required, has been reasonably demonstrated to
be available.

     Section 6.03 Control of Other Party's Business.  Nothing contained in this
Agreement shall give Parent or Merger Sub, directly or indirectly, the right to
control or direct the Company's operations prior to the Effective Time. Nothing
contained in this Agreement shall give the Company, directly or indirectly, the
right to control or direct Parent's or Merger Sub's operations prior to the
Effective Time. Prior to the Effective Time, each of the Company and Parent
shall exercise, consistent with the terms and conditions of this Agreement,
complete control and supervision over its respective operations.

to the Effective Time, to all of its properties, books, contracts, commitments
and records to the extent that the Company or any of its subsidiaries is not
under a legal obligation not to provide access or to the extent that such access
would not constitute a waiver of the attorney-client privilege and does not
unreasonably interfere with the business and operations of the Company; provided
that such right of access shall not include environmental inspections or testing
with respect to the properties of the Company's subsidiaries. During such
period, the Company shall, and shall cause its subsidiaries to, furnish promptly
to Parent (i) a copy of each material report, schedule and other document filed
or received by it or any of its subsidiaries pursuant to the requirements of
securities laws or filed with or sent to any regulatory agency or commission,

contemplated by this Agreement in accordance with the Confidentiality and
Standstill Agreement, dated as of September 9, 1999, between the Company and
Parent, as it may be amended from time to time (the "Confidentiality

(including reasonable attorney's fees and expenses), claims, damages or
liabilities or, subject to the last sentence of this Section 7.04(a), amounts
paid in settlement, arising out of actions or omissions occurring at or prior to
the Effective Time (and whether asserted or claimed prior to, at or after the
Effective Time) that are, in whole or in part, based on or arising out of the
fact that such person is or was a director, officer or employee of the Company
or a subsidiary of the Company (the "Indemnified Liabilities") and (ii) all
Indemnified Liabilities to the extent they are based on or arise out of or
pertain to the transactions contemplated by this Agreement. In the event of any
such loss, expense, claim, damage or liability (whether or not arising before
the Effective Time), Parent shall pay or cause to be paid the reasonable fees
and expenses of counsel selected by the Indemnified Parties, which counsel shall
be reasonably satisfactory to Parent, promptly after statements therefor are
received and otherwise advance to such Indemnified Party upon request
reimbursement of documented expenses reasonably incurred. Any determination
required to be made with respect to whether an Indemnified Party's conduct
complies with the standards set forth in Section 14A:3-5 of the NJBCA and the
Certificate of Incorporation or by-laws of the Company shall be made by
independent counsel mutually acceptable to Parent and the Indemnified Party.
Parent shall not be liable for any settlement effected without its written
consent (which consent shall not be unreasonably withheld or delayed).

     (b) Insurance.  For a period of six years after the Effective Time, Parent
shall (i) cause to be maintained in effect policies of directors' and officers'
liability insurance for the benefit of those persons who are currently covered
by such policies of the Company on terms no less favorable than the terms of
such current insurance coverage or (ii) provide tail coverage for such persons
which provides coverage for a period

                                       20
<PAGE>   83

of six years for acts prior to the Effective Time on terms no less favorable
than the terms of such current insurance coverage, in each case so long as the
annual premium therefor would not be in excess of 200% of the last annual
premium paid prior to the date of this Agreement; provided that if the annual
premium therefore would exceed such amount, Parent shall purchase as much
coverage as is available for such amount.

     (c) Successors.  In the event Parent or any of its successors or assigns
(i) consolidates with or merges into any other person and shall not be the
continuing or surviving corporation or entity of such consolidation or merger or
(ii) transfers all or substantially all of its properties and assets to any
person, then, and in either such case, proper provisions shall be made so that
the successors and assigns of Parent shall assume the obligations set forth in
this Section 7.04.

     (d) Survival of Indemnification.  To the fullest extent permitted by law,
from and after the Effective Time, all rights to indemnification as of the date
hereof in favor of the employees, agents, directors and officers of the Company
and its subsidiaries with respect to their activities as such prior to the
Effective Time, as provided in its respective articles of incorporation and
by-laws in effect on the date hereof, or otherwise in effect on the date hereof,
shall survive the Merger and shall continue in full force and effect for a
period of not less than six years from the Effective Time.

     (e) Benefit.  The provisions of this Section 7.04 are intended to be for
the benefit of, and shall be enforceable by, each Indemnified Party, his or her
heirs and his or her representatives.

     Section 7.05 Company Disclosure Schedule.  On the date hereof, the Company
has delivered to Parent a schedule (the "Company Disclosure Schedule"),
accompanied by a certificate signed by its Treasurer stating that the Company
Disclosure Schedule is being delivered pursuant to this Section 7.05. The
Company Disclosure Schedule constitutes an integral part of this Agreement and
modifies the respective representations, warranties, covenants or agreements of
the Company contained herein to the extent that such representations,
warranties, covenants or agreements expressly refer to the Company Disclosure
Schedule. Anything to the contrary contained herein or in the Company Disclosure
Schedule notwithstanding, any and all statements, representations, warranties or
disclosures set forth in the Company Disclosure Schedule shall be deemed to have
been made on and as of the date hereof.

     Section 7.06 Public Announcements.  Subject to each party's disclosure
obligations imposed by law or the rules of any applicable securities exchange or
Governmental Authority, the Company and Parent will cooperate with each other in
the development and distribution of all news releases and other public
information disclosures with respect to this Agreement or any of the
transactions contemplated hereby and shall not issue any public announcement or
statement with respect hereto without the consent of the other party (which
consent shall not be unreasonably withheld).

     Section 7.07 Rights Agreement.  Within five business days following the
execution of this Agreement, the Company shall take all action required to
render the rights (the "Company Rights") under the Company Rights Agreement
inapplicable to the Merger and shall amend the Company Rights Agreement so that
(i) Parent and Merger Sub will not become an "Acquiring Person" as a result of
the Merger, (ii) no "Distribution Date" or "Shares Acquisition Date" (as each
such term is defined in the Company Rights Agreement) will occur as a result of
the Merger, and (iii) all Company Rights issued and outstanding under the
Company Rights Agreement will expire immediately prior to the Effective Time.
Except as approved in writing by Parent, the Company shall not (i) amend the
Company Rights Agreement, (ii) redeem the Company Rights or (iii) take any
action with respect to, or make any determination under, the Company Rights
Agreement. If any "Distribution Date" or "Shares Acquisition Date" (as each such
term is defined in the Company Rights Agreement) or any event described in
Section 11(a)(ii) of the Company Rights Agreement occurs under the Company
Rights Agreement at any time during the period from the date of this Agreement
to the Effective Time, Parent and the Company shall make such adjustments to
this Agreement, if any, as Parent and the Company shall mutually agree so as to
preserve the economic benefits that Parent and the Company each reasonably
expected on the date of this Agreement to receive as a result of the
consummation of the Merger and the other transactions contemplated by the
Agreement.

     Section 7.08 Certain Employee Agreements and Arrangements.  Subject to
Section 7.09, Parent and the Surviving Corporation and its subsidiaries shall
honor, assume and perform, without modification, all contracts, agreements
(including without limitation the change in control agreements set forth in
Section 4.10(h) of the Company Disclosure Schedule), collective bargaining
agreements and commitments of the Company and its subsidiaries entered into
prior to the date hereof (or entered into by the Company or its subsidiaries
after the date hereof and prior to the Effective Time, to the extent permitted
by this Agreement) which apply to any current or former employee or current or
former director of the Company and its subsidiaries; provided, however, that the
foregoing shall not prevent Parent or the Surviving Corporation from enforcing
such contracts, agreements, collective bargaining agreements and commitments in
accordance with their terms, including, without limitation, any reserved right
to amend, modify, suspend, revoke or terminate any such contract, agreement,
collective bargaining agreement or commitment. Parent's goal is to create a
working environment within the Surviving Corporation which will satisfy the
objectives of all of the stakeholders of the Surviving Corporation.

     Section 7.09 Employee Benefit Plans.  (a) Subject to applicable law and
obligations under collective bargaining agreements, for a period of not less
than twelve months immediately following the Closing Date, the compensation,
benefits and coverage provided to those individuals who continue to be employees
of the Surviving Corporation, Parent or their respective subsidiaries (the
"Continuing Company Employees") pursuant to employee benefit plans or
arrangements maintained by Parent, the Surviving Corporation or their respective
subsidiaries shall be not less favorable than those provided to such employees
immediately prior to the Closing Date (it being understood that, after the
Closing Date, Company Common Stock, or options to purchase Company Common Stock,
need not be issued under any employee benefit plans or arrangements).
Notwithstanding the foregoing (but subject to Section 7.08), any such employee
benefit plan or arrangement that provides as of the date hereof for a
continuation period longer than twelve months shall be honored by Parent or the
Surviving Corporation. None of Parent, the Surviving Corporation or their
respective subsidiaries shall terminate any Continuing Company Employee during
the twelve-month period immediately following the Closing Date other than for
cause; provided that termination by Parent, the Surviving Corporation or their
respective subsidiaries shall not include voluntary retirement or voluntary
termination by a Continuing Company Employee.

     (b) Subject to applicable law and obligations under collective bargaining
agreements, Parent shall, or shall cause the Surviving Corporation to, give the
Continuing Company Employees full credit for purposes of eligibility, vesting,
benefit accrual and determination of the level of benefits under any pension
plans maintained by the Surviving Corporation in effect as of the Closing Date
for such Continuing Company Employees' service with the Company or any
subsidiary of the Company (or any prior employer) to the same extent recognized
by the Company or such subsidiary immediately prior to the Closing Date,
provided that such credit shall not be required to be given to the extent
crediting such service would result in duplication of benefits under such
pension plans.

     (c) Subject to applicable law and obligations under collective bargaining
agreements, Parent shall, or shall cause the Surviving Corporation to, (i) waive
all limitations as to preexisting conditions, exclusions and waiting periods
with respect to participation and coverage requirements applicable to the
Continuing Company Employees under any welfare benefit plan established to
replace any Company welfare benefit plans in which such Continuing Company
Employees may be eligible to participate after the Closing Date, other than
limitations or waiting periods that are already in effect with respect to such
Continuing Company Employees and that have not been satisfied as of the Closing
Date under any Company welfare plan maintained for the Continuing Company
Employees immediately prior to the Closing Date and (ii) provide each Continuing
Company Employee with credit for any co-payments and deductibles paid prior to
the Closing Date for the plan year in which the Closing Date occurs in
satisfying any applicable deductible or out-of-pocket requirements under any
welfare plans that such Continuing Company Employees are eligible to participate
in after the Closing Date.

     (d) Subject to applicable law and obligations under collective bargaining
agreements, Parent shall, or shall cause the Surviving Corporation to, provide,
for a period of not less than twelve months immediately following the Closing
Date, retiree medical plan coverage which shall be not less favorable than the
coverage

                                       22
<PAGE>   85

under the Company retiree medical policy as of the date hereof to any former
employee of the Company (and his or her eligible dependents) who is currently
receiving such benefits thereunder and to any current employee who retires prior
to the Closing Date (and his or her eligible dependents).

     Section 7.10 Expenses.  Subject to Section 9.03, all costs and expenses
incurred in connection with this Agreement and the transactions contemplated
hereby shall be paid by the party incurring such expenses.

     Section 7.11 Further Assurances.  Each party will, and will cause its
subsidiaries to, execute such further documents and instruments and take such
further actions as may reasonably be requested by any other party in order to
consummate the Merger in accordance with the terms hereof.

     Section 7.12 Community Involvement.  After the Effective Time, Parent will
or will cause the Surviving Corporation to make charitable contributions to the
communities served by the Surviving Corporation and otherwise maintain a level
of involvement in community activities in the State of New Jersey consistent
with the level of community development and related activities customarily
carried on by Parent's regulated utility subsidiaries.

     Section 7.13 Transition Planning.  (a) The Company and Parent shall each
appoint two persons to serve from time to time as their respective
representatives on a committee that will be responsible for coordinating
transition planning and implementation relating to the Merger. The initial
representatives of the Company shall be Michael Carmedy and Debbie Wrench. The
initial representatives of Parent shall be Andrew M. Chapman and Edward A.
Clerico.

     (b) Between the date of this Agreement and the Effective Time, Parent at
its discretion and expense may locate up to two of its representatives at the
offices of the Company (it being understood that such representatives shall not
interfere with the business and operations of the Company or its subsidiaries
and shall have no authority whatsoever with respect to the operation of the
business of the Company or any of its subsidiaries). During such period the
Company shall cause one or more of its designated representatives to consult as
reasonably requested by Parent with such representatives of Parent and to
discuss the general status of the business of the Company and its subsidiaries
consistent with Sections 6.03 and 7.01 hereof.

     Section 7.14 Company Convertible Subordinated Debentures.  At the written
request of Parent made after (i) receipt of the approval of the New Jersey Board
of Public Utilities referred to in Section 4.04(c) of the Company Disclosure
Schedule (which shall not be subject to any petition for appeal or rehearing),
(ii) satisfaction of the condition referred to in Section 8.01(e) hereof, and
(iii) satisfaction of the condition referred to in Section 8.02(e) hereof, the
Company shall forthwith call for redemption all convertible subordinated
debentures of the Company outstanding under the Indenture dated as of January 1,
1987, between the Company and The Bank of New York, as successor Trustee (the
"Indenture"), such redemption to occur at the earliest time permitted by the
terms of the Indenture. If the above-mentioned redemption has not occurred,
Parent shall, prior to the Effective Time, join in the execution and delivery by
the Company of a supplemental indenture described in Section 6.01(2) of the
Indenture, whereby, pursuant to Section 11.12 of the Indenture, Parent obligates
itself, after the Effective Time, to deliver the Merger Consideration upon
conversion of the convertible subordinated debentures of the Company outstanding
under such Indenture.

     Section 7.15 Compliance With ISRA.  Prior to the Closing Date, the Company
will undertake, at its own cost and expense, all activities necessary to
consummate the Merger in compliance with the Industrial Site Recovery Act,
N.J.S.A. 13:1K-6 et seq. ("ISRA"). For purposes of this Section 7.15, compliance
with ISRA shall be deemed to have been achieved upon receipt by the Company of
one of the following: (i) a "Letter of Non-Applicability" issued by the New
Jersey Department of Environmental Protection ("NJDEP") with respect to the
Merger, (ii) approval of a "Negative Declaration" by the NJDEP, (iii) a "no
further action letter" issued by the NJDEP, or (iv) an executed "Remediation
Agreement" with the NJDEP (as each such term is defined pursuant to ISRA);
provided, however, that in no event shall the Company be required to execute a
Remediation Agreement with the NJDEP which, in the Company's reasonable

                                       23
<PAGE>   86

judgment, could be expected to have a Company Material Adverse Effect, unless
such Remediation Agreement by its terms would be binding on the Company only if
the Merger is consummated.

     Section 7.16 Stock Options and Restricted Stock.  (a) At the Effective
Time, each option under the Company's 1987 Company Stock Option Plan and the
1998 Company Stock Option Plan (the "Company Options") which is vested and
outstanding immediately prior thereto shall be cancelled, and in exchange
therefor, each holder shall have the right to receive (i) the Merger
Consideration into which the share or shares of Company Common Stock issuable
upon exercise of such Company Option would have been converted if such Company
Option had been exercised immediately prior to the Effective Time, reduced by
(ii) (A) the aggregate exercise price for the shares of Company Common Stock
then issuable upon exercise of such Company Option and (B) the amount of any
withholding taxes which may be required thereon. The Company or the Company's
Board of Directors may give any notice or take any other action prior to the
Effective Time that is permitted by the terms of any Company Option in order to
cause the vesting thereof.

     (b) Between the date of this Agreement and the Closing Date, the Company or
the Company's Board of Directors may take all actions as may be necessary or
desirable in order that all restrictions and vesting provisions applicable to
the restricted stock awards heretofore granted under the Company 1990
Performance Stock Program, the Company Management Incentive Plan and the Company
1998 Directors Stock Plan are cancelled and eliminated as of the Effective Time,
so that the holders of such restricted stock may receive in accordance with
Section 2.02 the Merger Consideration applicable to such restricted stock (in
return for customary releases).

     (c) From and after the date of this Agreement, the Company shall not permit
any additional options to purchase shares of Company Common Stock or grants of
restricted Company Common Stock to be issued or granted under the Company's
stock option plans, performance stock plans, management incentive plans,
directors stock plans or otherwise.

                                  ARTICLE VIII

                                   CONDITIONS

     Section 8.01 Conditions to Each Party's Obligation to Effect the

the following conditions:

          (a) Company Shareholder Approvals.  The Company Shareholders' Approval
     shall have been obtained.

          (b) HSR Act.  Any waiting period (and any extension thereof)
     applicable to the consummation of the Merger under the Hart-Scott-Rodino
     Antitrust Improvements Act of 1976, as amended, shall have expired or been
     terminated.

          (c) No Injunction.  No temporary restraining order or preliminary or
     permanent injunction or other order by any federal or state court
     preventing consummation of the Merger shall have been issued and be
     continuing in effect, and the Merger and the other transactions
     contemplated hereby shall not have been prohibited under any applicable
     federal or state law or regulation.

          (d) Statutory Approvals.  The Company Required Statutory Approvals and
     Parent Required Statutory Approval shall have been obtained at or prior to
     the Effective Time; and such approvals shall have become Final Orders. A
     "Final Order" means action by the relevant regulatory authority (i) which
     has not been reversed, stayed, enjoined, set aside, annulled or suspended,
     (ii) with respect to which any waiting period prescribed by law before the
     transactions contemplated hereby may be consummated has expired, and as to
     which all conditions to the consummation of such transactions prescribed by
     law, regulation or order have been satisfied, and (iii) as to which all
     periods prescribed by law during which petitions for appeal or rehearing

     achieved as set forth in Section 7.15.

     performed in all material respects each of its agreements and covenants
     required by this Agreement to be so performed by the Company at or prior to
     the Closing.

          (b) Representations and Warranties.  The representations and
     warranties of the Company set forth in this Agreement shall be true and
     correct on and as of the Closing Date with the same effect as though such
     representations and warranties had been made on and as of the Closing Date
     (except for representations and warranties that expressly speak only as of
     a specific date or time other than the date hereof or the Closing Date,
     which need only be true and correct as of such date or time) except for
     such failures of representations or warranties to be true and correct
     (without regard to any materiality qualifications contained therein) which,
     individually and in the aggregate, would not reasonably be expected to
     result in a Company Material Adverse Effect.

          (c) Closing Certificates.  Parent shall have received a certificate
     signed by the President of the Company, dated the Closing Date, to the
     effect that, to the best of such officer's knowledge, the conditions set

     and circumstances described in Section 4.06 of the Company Disclosure
     Schedule or the Company SEC Reports filed prior to the date hereof which
     could reasonably be expected to have a Company Material Adverse Effect.

          (e) Company Required Statutory Approvals.  The Company Required
     Statutory Approvals shall not impose terms or conditions specifically in
     relation to the Merger which, in the reasonable judgment of Parent, could
     be expected to have a material adverse effect on the business, properties,
     financial condition or results of operations of the Surviving Corporation
     and its subsidiaries taken as a whole if the Merger were consummated.

          (f) Company Required Consents.  The Company Required Consents the
     failure of which to obtain would reasonably be expected to have a Company
     Material Adverse Effect shall have been obtained.

     Section 8.03 Conditions to Obligation of the Company to Effect the
Merger.  The obligation of the Company to effect the Merger shall be further
subject to the satisfaction (or waiver by the Company), on or prior to the
Closing Date, of each of the following conditions:

     (except for representations and warranties that expressly speak only as of
     a specific date or time other than the date hereof or the Closing Date,
     which need only be true and correct as of such date or time) except for
     such failures of representations or warranties to be true and correct
     (without regard to any materiality qualifications contained therein) which,
     individually and in the aggregate, would not reasonably be expected to
     result in a Parent Material Adverse Effect.

                                       25
<PAGE>   88

          (c) Closing Certificates.  The Company shall have received a
     certificate signed by the Chief Executive Officer of Parent, dated the
     Closing Date, to the effect that, to the best of such officer's knowledge,
     the conditions set forth in Section 8.03(a) and Section 8.03(b) have been
     satisfied.

                                   ARTICLE IX

                       TERMINATION, AMENDMENT AND WAIVER

     Section 9.01 Termination.  This Agreement may be terminated, and the Merger
and other transactions contemplated hereby may be abandoned, at any time prior
to the Effective Time, whether before or after approval by the shareholders of
the respective parties hereto contemplated by this Agreement:

          (a) by mutual written consent of the Boards of Directors of the
     Company and Parent;

          (b) by Parent or the Company, by written notice to the other parties,
     if the Effective Time shall not have occurred on or before the date which
     is nine months from the date hereof (the "Initial Termination Date");
     provided, however, that (i) the right to terminate the Agreement under this
     Section 9.01(b) shall not be available to any party whose failure to
     fulfill any obligation under this Agreement has been the cause of, or
     resulted directly or indirectly in, the failure of the Effective Time to
     occur on or before such date; (ii) if on the Initial Termination Date the
     condition to the Closing set forth in Section 8.01(d) shall not have been
     fulfilled but all other conditions to the Closing shall be fulfilled or
     shall be capable of being fulfilled on such date, then the Initial
     Termination Date shall be extended to the date which is twelve months from
     the date hereof (the "Extended Termination Date"); and (iii) if on the
     Extended Termination Date the condition to the Closing set forth in Section
     8.01(d) shall not have been fulfilled solely because the periods described
     in clause (iii) of such Section 8.01(d) shall not have expired, the
     Extended Termination Date shall be extended to the date of expiration of
     such periods;

          (c) by Parent or the Company, by written notice to the other parties,
     if the Company Shareholders' Approval shall not have been obtained at a
     duly held Company Special Meeting, including any adjournments thereof;

          (d) by Parent or the Company, if any law, order, rule or regulation
     binding upon either of them is adopted or issued, which has the effect, as
     supported by the written opinion of outside counsel for such party, of
     prohibiting the Merger, or if any court of competent jurisdiction in the
     United States or any State shall have issued an order, judgment or decree
     permanently restraining, enjoining or otherwise prohibiting the Merger, and
     such order, judgment or decree shall have become final and nonappealable;
     (provided that the right to terminate this Agreement under this Section
     9.01(d) shall not be available to any party that has not defended such
     lawsuit or other legal proceeding (including seeking to have any stay or
     temporary restraining order entered by any court or other Governmental
     Authority vacated or reversed));

          (e) by the Company if (i) the Company's Board of Directors shall have
     determined in good faith, based on the advice of outside counsel, that it
     is necessary, in order to act consistently with its fiduciary duties to the
     Company's shareholders under applicable law, to terminate this Agreement in
     order to enter into an agreement with respect to, or to consummate a
     transaction constituting, a Superior Proposal, (ii) the Company shall have
     given notice to Parent advising Parent that the Company has received a
     Superior Proposal from a third party, specifying the material terms and
     conditions (including the identity of the third party), and that the
     Company intends to terminate this Agreement in accordance with this Section
     9.01(e), (iii) either (A) Parent shall not have revised its proposal for
     the Merger within 10 days from the time on which such notice is deemed to
     have been given to Parent or (B) if Parent within such period shall have
     delivered to the Company's Board of Directors a firm revised proposal for
     the Merger, the Company's Board of Directors, after receiving advice from
     the Company's financial advisor, shall have determined in its good faith
     judgment that notwithstanding a binding commitment to consummate this
     Agreement and concessions that may be offered by Parent's revised proposal,
     the third party's Alternative Proposal is superior to Parent's revised
     proposal for the Merger, and (iv) the Company, at the time of such
     termination, pays the expenses and the termination fee in accordance with
     Section 9.03(b);

                                       26
<PAGE>   89

          (f) by the Company, by written notice to Parent, if (i) there exist
     breaches of the representations and warranties of Parent made herein as of
     the date hereof which breaches, individually or in the aggregate, would
     reasonably be expected to give rise to the failure of the condition set
     forth in 8.03(b), and such breaches shall not have been remedied within 20
     days after receipt by Parent of notice in writing from the Company,
     specifying the nature of such breaches and requesting that they be
     remedied, or (ii) there shall have been a material breach of any agreement
     or covenant of Parent hereunder, which breach would reasonably be expected
     to give rise to the failure of the condition set forth in Section 8.03(a),
     and such breach shall not have been remedied within 20 days after receipt
     by Parent of notice in writing from the Company, specifying the nature of
     such failure and requesting that it be remedied; or

          (g) by Parent, by written notice to the Company, if (i) there exist
     breaches of the representations and warranties of the Company made herein
     as of the date hereof which breaches, individually or in the aggregate,
     would reasonably be expected to give rise to the failure of the condition
     set forth in Section 8.02(b), and such breaches shall not have been
     remedied within 20 days after receipt by the Company of notice in writing
     from Parent, specifying the nature of such breaches and requesting that
     they be remedied, (ii) there shall have been a material breach of any
     agreement or covenant of the Company hereunder, which breach would
     reasonably be expected to give rise to the failure of the condition set
     forth in Section 8.02(a), and such breach shall not have been remedied
     within 20 days after receipt by the Company of notice in writing from
     Parent, specifying the nature of such failure and requesting that it be
     remedied, or (iii) the Board of Directors takes any action to withdraw or
     modify in a manner adverse to Parent or Merger Sub its approvals or
     recommendation of the Merger or this Agreement or to recommend any
     Alternative Proposal or shall resolve to do any of the foregoing.

     Section 9.02 Effect of Termination.  In the event of a valid termination of
this Agreement by either the Company or Parent pursuant to Section 9.01, this
Agreement shall forthwith become null and void and there shall be no liability
on the part of either the Company or Parent or their respective officers or
directors hereunder, except that Section 7.10, Section 9.03, the agreement
contained in the last sentence of Section 7.01, and Sections 10.08, 10.09 and
10.10 shall survive the termination.

     Section 9.03 Termination Fees; Expenses.  (a) If this Agreement is
terminated by Parent pursuant to Section 9.01(g)(i) or (ii), then the Company
shall promptly (but not later than five business days after receiving notice of
termination) pay to Parent in cash an amount equal to all documented
out-of-pocket expenses and fees incurred by Parent (including, without
limitation, fees and expenses payable to all legal, accounting, financial, and
other professionals arising out of, in connection with or related to the
transactions contemplated by this Agreement) not in excess of $5 million. If
this Agreement is terminated by the Company pursuant to Section 9.01(f), then
Parent shall promptly (but not later than five business days after receiving

documented out-of-pocket expenses and fees incurred by the Company (including,
without limitation, fees and expenses payable to all legal, accounting,
financial, and other professionals arising out of, in connection with or related
to the transactions contemplated by this Agreement) not in excess of $5 million.

     (b) In the event that (i) this Agreement is terminated by the Company
pursuant to Section 9.01(e) or (ii) any person or group shall have made an
Alternative Proposal that has not been withdrawn and this Agreement is
terminated by (A) Parent or the Company pursuant to Section 9.01(c) because the
Company Shareholders' Approval is not obtained, (B) Parent pursuant to Section
9.01(g)(iii), or (C) by the Company pursuant to Section 9.01(b), then the

termination fee of $16.5 million plus an amount equal to all documented
out-of-pocket expenses and fees incurred by Parent arising out of, or in
connection with or related to, the transactions contemplated by this Agreement,
not in excess of $5 million in the aggregate; provided, however, that if this

     (c) Nature of Fees.  The parties agree that the agreements contained in
this Section 9.03 are an integral part of the Merger and the other transactions
contemplated hereby and constitute liquidated damages and not a penalty. The
parties further agree that if any party is or becomes obligated to pay a
termination fee or expenses pursuant to Sections 9.03(a) or 9.03(b), the right
to receive such termination fee or expenses shall be the sole remedy of the
other party with respect to the facts and circumstances giving rise to such
payment obligation. If this Agreement is terminated by a party as a result of a
willful breach of a representation, warranty, covenant or agreement by the other
party, the non-breaching party may pursue any remedies available to it at law or
in equity and shall be entitled to recover any additional amounts thereunder.
Notwithstanding anything to the contrary contained in this Section 9.03, if one
party fails to promptly pay to the other any fee or expense due under this
Section 9.03, in addition to any amounts paid or payable pursuant to Section,
the defaulting party shall pay the costs and expenses (including legal fees and
expenses) in connection with any action, including the filing of any lawsuit or
other legal action, taken to collect payment, together with interest on the
amount of any unpaid fee at the publicly announced prime rate of The Bank of New
York from the date such fee was required to be paid.

     Section 9.04 Amendment.  This Agreement may be amended at any time before
or after approval hereof by the shareholders of the Company and prior to the
Effective Time, but after such approval only to the extent permitted by
applicable law. This Agreement may not be amended except by an instrument in
writing signed on behalf of each of the parties hereto.

     Section 9.05 Extension or Waiver.  At any time prior to the Effective Time,
the Parent or the Company may (a) extend the time for the performance of any of
the obligations or other acts of the other parties hereto, (b) waive any
inaccuracies in the representations and warranties contained herein or in any
document delivered pursuant hereto and (c) waive compliance with any of the
agreements or conditions contained herein, to the extent permitted by applicable
law. Any agreement on the part of a party hereto to any such extension or waiver
shall be valid if set forth in an instrument in writing signed on behalf of such
party. No waiver by any party of any term or condition of this Agreement, in any
one or more instances, shall be deemed to be or construed as a waiver of the
same or any other term or condition of this Agreement on any future occasion.

     Section 9.06 Procedure for Termination, Amendment, Extension or Waiver.  A
termination of this Agreement pursuant to Section 9.01, an amendment of this
Agreement pursuant to Section 9.04 or an extension or waiver pursuant to Section
9.05 shall, in order to be effective, require, in the case of the Company,
action by its Board of Directors or the duly authorized committee or designee of
its Board of Directors to the extent permitted by law and its Certificate of
Incorporation and, in the case of Parent and Merger Sub, action by its Board of
Directors or the duly authorized committee or designee of its Board of Directors
to the extent permitted by law and its charter or governing documents.

[SALOMON SMITH BARNEY LETTERHEAD]

November 21, 1999

The Board of Directors
E'town Corporation
600 South Avenue
Westfield, New Jersey 07091

Members of the Board:

     You have requested our opinion as to the fairness, from a financial point
of view, to the holders of the common stock of E'town Corporation ("E'town") of
the Merger Consideration (defined below) provided for in the Agreement and Plan
of Merger, dated as of November 21, 1999 (the "Merger Agreement"), among E'town,
Thames Water Pic ("Thames") and Edward Acquisition Corp., an indirectly wholly
owned subsidiary of Thames ("Merger Sub"). As more fully described in the Merger
Agreement, (i) Merger Sub will be merged with and into E'town (the "Merger") and
(ii) each outstanding share of the common stock, no par value, of E'town (the
"E'town Common Stock") will be converted into the right to receive $68.00 in
cash (the "Merger Consideration").

     In arriving at our opinion, we reviewed the Merger Agreement and held
discussions with certain senior officers, directors and other representatives
and advisors of E'town and certain senior officers and other representatives and
advisors of Thames concerning the business, operations and prospects of E'town.
We examined certain publicly available business and financial information
relating to E'town as well as certain financial forecasts for E'town and other
information and data for E'town which were provided to or otherwise discussed
with us by the management of E'town. We reviewed the financial terms of the
Merger as set forth in the Merger Agreement in relation to, among other things:
current and historical market prices and trading volumes of the E'town Common
Stock; the historical and projected earnings and other operating data of E'town;
and the capitalization and financial condition of E'town. We considered, to the
extent publicly available, the financial terms of other transactions recently
effected which we considered relevant in evaluating the Merger and analyzed
certain financial, stock market and other publicly available information
relating to the businesses of other companies whose operations we considered
relevant in evaluating those of E'town. In addition to the foregoing, we
conducted such other analyses and examinations and considered such other
financial, economic and market criteria as we deemed appropriate in arriving at
our opinion.

     In rendering our opinion, we have assumed and relied, without independent
verification, upon the accuracy and completeness of all financial and other
information and data publicly available or furnished to or otherwise reviewed by
or discussed with us. With respect to financial forecasts and other information
and data provided to or otherwise reviewed by or discussed with us, we have been
advised by the management of E'town that such forecasts and other information
and data were reasonably prepared on bases reflecting the best currently
available estimates and judgments of the management of E'town as to the future
financial performance of E'town. We have assumed, with your consent, that in the
course of obtaining the necessary regulatory approvals for the Merger, no
limitations, restrictions or conditions will be imposed that would have a
material adverse effect on the contemplated benefits of the Merger to E'town. We
have not made or been provided with an independent evaluation or appraisal of
the assets or liabilities (contingent or otherwise) of E'town nor have we made
any physical inspection of the properties or assets of E'town. In connection
with our engagement, we were not requested to, and we did not, solicit third
party proposals for the possible acquisition of all or a part of E'town. We
express no view as to, and our opinion does not address, the relative merits of
the Merger as compared to any alternative business strategies that might exist
for E'town or the effect of any other transaction in which E'town might engage.
Our opinion is necessarily based upon information available to us, and
financial, stock market and other conditions and circumstances existing and
disclosed to us, as of the date hereof.

     Salomon Smith Barney Inc. has acted as financial advisor to E'town in
connection with the proposed Merger and will receive a fee for such services, a
significant portion of which is contingent upon the consummation of the Merger.
We and our affiliates have in the past provided investment banking services to

<PAGE>   96
The Board of Directors
E'town Corporation

Page 2

E'town unrelated to the proposed Merger, for which services we have received
compensation. In the ordinary course of our business, we and our affiliates may
actively trade or hold the securities of E'town and Thames for our own account
or for the account of our customers and, accordingly, may at any time hold a
long or short position in such securities. In addition, we and our affiliates
(including Citigroup Inc. and its affiliates) may maintain relationships with
E'town, Thames and their respective affiliates.

     Our advisory services and the opinion expressed herein are provided for the
information of the Board of Directors of E'town in its evaluation of the
proposed Merger, and our opinion is not intended to be and does not constitute a
recommendation to any shareholder as to how such shareholder should vote on the
proposed Merger.

     Based upon and subject to the foregoing, our experience as investment
bankers, our work as described above and other factors we deemed relevant, we
are of the opinion that, as of the date hereof, the Merger Consideration is
fair, from a financial point of view, to the holders of E'town Common Stock.

Very truly yours,
