                  SUBJECT TO COMPLETION, DATED AUGUST 16, 1999

                              [CTG RESOURCES LOGO]

Dear Shareholder:

                   PROPOSED MERGER -- YOUR VOTE IS IMPORTANT

    You are cordially invited to attend a special meeting of shareholders of CTG
Resources, Inc., scheduled to be held on Monday, October 18, 1999, at the
offices of CTG Resources, 100 Columbus Boulevard, Hartford, Connecticut,
commencing at 10:30 a.m. Your board of directors and management look forward to
greeting those shareholders able to attend. Parking will be available.

    The boards of directors of Energy East Corporation and CTG Resources have
agreed to a merger in which CTG Resources will merge into Oak Merger Co., a
wholly owned subsidiary of Energy East.

    At the meeting, you will be asked to approve this merger.

    In exchange for each share of CTG Resources common stock, CTG Resources
shareholders will have the option to receive either $41.00 in cash or a number
of shares of Energy East common stock valued at $41.00, subject to restrictions
on the maximum and minimum number of Energy East shares to be issued. The number
of Energy East shares to be exchanged for each CTG Resources share will be
between 1.3609 and 1.7320, based on the value of Energy East shares during the
20-trading-day period ending two trading days before the effective time of the
merger. CTG Resources shareholders can choose to convert some of their CTG
Resources shares into cash and others into Energy East shares.

    Under the merger agreement, 55% of the CTG Resources shares must be
exchanged for cash, and 45% must be exchanged for Energy East shares. Therefore,
if shareholders owning more than 55% of the CTG Resources shares elect to
receive cash, the number of CTG Resources shares that will be converted into
cash will be less than the number elected. Similarly, if shareholders owning
more than 45% of the CTG Resources shares elect to receive Energy East shares,
the number of CTG Resources shares that will be converted into Energy East
shares will be less than the number elected.

    Your board of directors recommends a vote "FOR" this proposal.

    PLEASE SEE THE SECTION ENTITLED "RISK FACTORS" BEGINNING ON PAGE 19 FOR A
DISCUSSION OF POTENTIAL RISKS INVOLVED IN THE MERGER.

    CTG Resources and Energy East cannot complete the merger unless CTG
Resources shareholders approve the merger agreement. We have scheduled a special
meeting of shareholders to vote on this matter.

    YOUR VOTE IS VERY IMPORTANT.  Regardless of the number of shares you own, it
is important that they be represented and voted at the meeting, whether or not
you plan to attend. Accordingly, you are requested to exercise your vote by (1)
signing, dating and mailing the enclosed proxy in the postage prepaid return
envelope provided for your convenience or (2) appointing and directing your
proxies by telephone in accordance with the instructions on the proxy card.

    Only shareholders of record of CTG Resources on August 23, 1999 are entitled
to attend and vote at the special meeting.

    This proxy statement/prospectus contains answers to frequently asked
questions; it also contains a summary description of the merger and other
related matters (beginning on page 1), followed by a more detailed discussion of
the merger and these matters. Because these answers and this summary are not, by
their nature, detailed, we urge you to read this proxy statement/prospectus in
its entirety. We encourage you to read the entire proxy statement/prospectus
carefully.

    In addition, you may obtain information about the two companies from
documents they have filed with the Securities and Exchange Commission.

    Your interest and participation in the affairs of CTG Resources are
sincerely appreciated.

REGULATOR HAS APPROVED THE MERGER OR THE ISSUANCE OF ENERGY EAST SHARES, OR

OFFENSE.

    This document is also the prospectus of Energy East for the shares that it
will issue in connection with the merger. Energy East shares are traded on the
New York Stock Exchange under the symbol "NEG." On August 13, 1999, the last
full trading day for which information was available prior to the date of this
proxy statement/prospectus, the closing sales price for Energy East shares, as
reported in THE WALL STREET JOURNAL's New York Stock Exchange Composite
Transactions Report, was $25.69 per share.

    Energy East has furnished all the information in this proxy
statement/prospectus concerning Energy East, and CTG Resources has furnished all
the information concerning CTG Resources.

                         TO BE HELD ON OCTOBER 18, 1999

To the Shareholders of CTG Resources, Inc.:

    The CTG Resources board of directors is pleased to provide you with notice
of and cordially invites you to attend in person or by proxy the special meeting
of CTG Resources shareholders, which will be held at the offices of CTG

subsidiary of Energy East.

    CTG Resources shareholders who do not vote their CTG Resources shares to
approve the merger agreement and who deliver to CTG Resources before the vote is
taken a notice of intent to exercise dissenters' rights of appraisal will be
entitled to assert these rights under Connecticut law. If the merger agreement
is approved, these shareholders will receive a cash payment representing the
fair value of the shares they currently hold, and not the consideration payable
in the merger. A copy of the sections of Connecticut law that govern this
process is attached as Appendix C to the accompanying proxy
statement/prospectus.

    Additional information about the merger may be found in the accompanying
proxy statement/ prospectus.

    Only CTG Resources shareholders as of the close of business on August 23,
1999 are entitled to notice of and to vote at the special meeting or any
postponements or adjournments thereof.

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

    Please sign, date and return the accompanying proxy in the enclosed
addressed envelope, which requires no postage if mailed in the United States. If
you prefer, you may vote by telephone in accordance with the instructions on the
proxy card. In either case, you may revoke your proxy at any time before the
vote is taken by delivering to the Secretary a written revocation or a proxy
with a later date or by oral revocation in person at the special meeting.

                                          By Order of the Board of Directors,

                     QUESTIONS AND ANSWERS ABOUT THE MERGER

Q.  WHAT WILL HAPPEN IN THE PROPOSED TRANSACTION?

A.  CTG Resources will become a direct subsidiary of Energy East by merging into
    Oak Merger Co., a wholly owned subsidiary of Energy East.

Q.  WHY HAS CTG RESOURCES DECIDED TO MERGE?

A.  The CTG Resources board of directors and management believe that the merger
    will help position the combined company to become one of the premier
    distribution companies for energy distribution and other energy-related
    services in the northeastern United States by increasing financial
    flexibility and providing strategic growth opportunities that will benefit
    the combined company and its shareholders, customers and employees in a
    manner that CTG Resources could not achieve on its own.

    Please read the more detailed description of CTG Resources's reasons for the
    merger on pages 33 to 34.

Q.  WHAT WILL CTG RESOURCES SHAREHOLDERS RECEIVE?

A.  CTG Resources shareholders will have the option to elect to receive, in
    exchange for each of their CTG Resources shares, either $41.00 in cash or a
    number of Energy East shares valued at $41.00, subject to limitations on the
    maximum and minimum number of Energy East shares to be issued. The number of
    Energy East shares to be exchanged for each CTG Resources share will be
    between 1.3609 and 1.7320, based on the value of Energy East shares during
    the 20-trading-day period ending two trading days before the effective time
    of the merger. CTG Resources shareholders can choose to convert some of
    their CTG Resources shares into cash and others into Energy East shares.

    Please read the more detailed description of the consideration to be issued
    in the merger on pages 58 to 59.

Q.  WILL I RECEIVE THE SPECIFIC AMOUNTS OF CASH AND STOCK THAT I ELECT?

A.  Due to a requirement contained in the merger agreement that 55% of the CTG
    Resources shares must be converted into cash and 45% must be converted into
    Energy East shares, the amounts of cash and stock you receive may be
    different from the amounts you elect. For example, if CTG Resources
    shareholders owning more than 55% of CTG Resources shares elect to receive
    cash, the number of CTG Resources shares converted into cash will be less
    than the number elected. Similarly, if CTG Resources shareholders owning
    more than 45% of CTG Resources shares elect to receive Energy East shares,
    the number of CTG Resources shares converted into Energy East shares will be
    less than the number elected.

    For tax reasons that are explained on page 59, Energy East might have to
    increase the number of CTG Resources shares converted into Energy East
    shares and decrease the number of CTG Resources shares converted into cash.

    Energy East will not issue any fractional shares in the merger. Instead, you
    will get cash for any fractional shares that you would otherwise receive.

    If you participate in the CTG Dividend Reinvestment Plan, cash that you
    receive in this plan in the merger will be distributed to you or reinvested
    in accordance with the terms of the plan and the merger agreement.

    Please read the more detailed description of the allocation procedures on
    page 59.

                                       1
<PAGE>
Q.  WHAT DO I NEED TO DO NOW?

A.  After you carefully read this document, please, as soon as possible, (1)
    complete, sign, date and mail your proxy card in the enclosed return
    envelope or (2) appoint and direct your proxies by telephone in accordance
    with the instructions on your proxy card. That way, your CTG Resources
    shares can be represented at the special meeting.

    If you participate in the CTG Resources Dividend Reinvestment Plan, and you
    own uncertificated shares, your proxy card covers both plan shares and
    certificated shares unless the registrations are different. If you have
    registrations in different names, you will receive a separate proxy card for
    each name registration. If a broker holds your shares as nominee, you will
    receive a voter-information form from your broker.

    CTG Resources and Energy East cannot complete the merger unless two-thirds
    of the outstanding CTG Resources shares approve the merger agreement. Your
    vote is very important.

    THE CTG RESOURCES BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS VOTING "FOR"
    APPROVAL OF THE MERGER AGREEMENT.

Q.  SHOULD I SEND IN MY STOCK CERTIFICATES NOW?

A.  No. You should continue to hold your stock certificates until we send you a
    form of election that you can use to indicate your preference as to the type
    of payment you would like to receive in the merger. You will not receive
    this notice until after the special meeting has occurred, but not less than
    30 days prior to the effective time of the merger. At that time, you will be
    given instructions for sending in your certificates. If you currently hold
    your CTG Resources shares in uncertificated form, for example, through the
    CTG Dividend Reinvestment Plan, or if a broker holds your shares as nominee,
    you do not need to request that certificates be issued. After the merger is
    completed, you will receive written information on the exchange of these
    shares.
Q.  WHO MUST APPROVE THE MERGER?

A.  In addition to approvals by the Energy East, CTG Resources and Oak Merger
    Co. boards of directors, all of which have already been obtained, the merger
    must be approved by the holders of two-thirds of the CTG Resources shares.
    We must also obtain some regulatory approvals for the merger. Please read
    the more detailed description of the regulatory approvals on pages 43 to 46.

Q.  DO ENERGY EAST SHAREHOLDERS VOTE ON THE MERGER AGREEMENT?

A.  No. Only CTG Resources shareholders vote on the merger.

Q.  WHEN DO YOU 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 in the middle of the year 2000.

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

A.  If a broker holds your CTG Resources shares as nominee, he will not be able
    to vote them without instructions from you.

    If you mark your proxy "Abstain," select the "Abstain" option when
    registering your vote by telephone or do not instruct your broker on how to
    vote, your shares will have the effect of a vote against the merger
    agreement.

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

A.  Yes. If you would like to revoke your proxy in writing, you must deliver to
    the Secretary of CTG Resources, at any time before the vote has been taken
    at the special meeting, a written revocation or a proxy bearing a later
    date. We will count only the most recently dated proxy at the special
    meeting.

    You should send these to: CTG Resources, Inc., P.O. Box 1500, 100 Columbus
    Boulevard, Hartford, Connecticut 06144-1500, Attention: Secretary.

    Alternatively, you may attend the special meeting in person and revoke your
    proxy orally before the vote takes place.

Q.  WHOM SHOULD I CALL IF I HAVE ANY ADDITIONAL QUESTIONS OR WANT TO REQUEST A
    COPY OF THIS DOCUMENT?

A.  You may call D.F. King & Co., Inc., our proxy solicitor, at (800) 755-7250
    with respect to questions regarding voting or to request a copy of this
    document.

Q.  ON WHAT OTHER MATTERS WILL CTG RESOURCES SHAREHOLDERS VOTE AT THE SPECIAL
    MEETING?

A.  CTG Resources shareholders will not vote on any other matters at the special
    meeting, except possibly procedural items relating to the conduct of the
    special meeting.

Q.  ASSUMING I RECEIVE ENERGY EAST SHARES IN THE MERGER, WILL MY RIGHTS AS A
    SHAREHOLDER CHANGE AS A RESULT OF THE MERGER?

A.  Yes. For a summary of material differences between the rights of CTG
    Resources shareholders and the rights of Energy East shareholders, see pages
    92 to 98 of this document.

Q.  I UNDERSTAND THAT ENERGY EAST IS INVOLVED IN SOME OTHER MERGERS. IS ITS
    MERGER WITH CTG RESOURCES CONTINGENT ON THOSE OTHER MERGERS BEING COMPLETED?

A.  Consistent with Energy East's strategy of selectively growing its energy
    distribution business in the northeastern United States, Energy East entered
    into a merger agreement in April 1999 with Connecticut Energy, an exempt
    public utility holding company located in Connecticut, and a merger
    agreement in June 1999 with CMP Group, an exempt public utility holding
    company located in Maine. The merger between CTG Resources and Energy East
    is not contingent upon the completion of these mergers.

    For more information on the Connecticut Energy and CMP Group mergers, please
    read the pro forma financial statements and accompanying notes on pages 72
    to 91.

Q.  WHERE CAN I FIND MORE INFORMATION ABOUT ENERGY EAST, CTG RESOURCES,
    CONNECTICUT ENERGY AND CMP GROUP?

A.  Various sources described under "Where You Can Find More Information" on
    pages 101 and 102 of this document explain how you can obtain further
    information.

           CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

    This document contains some forward-looking statements that involve risks
and uncertainties. We may make these statements about the financial condition,
results of operations and business of Energy East and CTG Resources. These
statements may be made directly in this document referring to Energy East or CTG
Resources, or may be "incorporated by reference" from other documents filed with
the Securities and Exchange Commission. This document may also include
statements relating to the period following the completion of the merger. You
can find many of these statements by looking for words such as "believes,"
"expects," "anticipates," "estimates" or similar expressions in this document or
in the documents incorporated by reference.

    These forward-looking statements are subject to numerous assumptions, risks
and uncertainties. Factors that may cause actual results to differ from those
indicated by such forward-looking statements include, among others, the
following:

    - the fact that these forward-looking statements are based on information of
      a preliminary nature which may be subject to further and continuing review
      and adjustment;

    - the risk of a significant delay in the expected completion of, and
      unexpected consequences resulting from, the merger;

    - the highly competitive nature of the electric, natural gas and energy
      marketing industries, including the speed and degree to which competition
      enters these industries and the risk that other companies will further
      expand into markets in which Energy East or CTG Resources operates;

    - the risk that fluctuating energy prices may affect revenues;

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

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

    - problems arising from the potential inability of computers to recognize
      and process properly date-sensitive information beyond January 1, 2000,
      which may result in an interruption in, or a failure of, normal business
      activities or operations;

    - the risks associated with future weather conditions;

    - the risks associated with changes in customer demographics in the service
      territories of Energy East or CTG Resources and the pursuit of new
      markets;

    - difficulties in completing Energy East's proposed mergers with Connecticut
      Energy and CMP Group and complications arising from the integration of CTG
      Resources, Connecticut Energy and CMP Group with Energy East;

    - other considerations that may be disclosed from time to time in Energy
      East's or CTG Resources's publicly disseminated documents or filings;

    - regulatory issues, including the pace of deregulation of the retail
      natural gas and electricity markets in the United States;

    - inflation; and

    - exposure to environmental issues and liabilities, as well as potential
      changes in environmental regulations.

    You should not place undue reliance on the forward-looking statements, which
speak only as of the date of this document or, in the case of a document
incorporated by reference, the date of that document.

    The cautionary statements in this section expressly qualify, in their
entirety, all subsequent forward-looking statements attributable to Energy East,
CTG Resources or any person acting on their behalf. Neither Energy East nor CTG
Resources undertakes any obligation to release publicly any revisions to the
forward-looking statements to reflect events or circumstances occurring after
the date of this document.

                                 THE COMPANIES

ENERGY EAST (SEE PAGES 22 AND 23)
Energy East Corporation
P.O. Box 1196
Stamford, Connecticut 06904-1196
(203) 325-0690

    Energy East is a holding company that was organized under the laws of the
State of New York in 1997. Energy East, through its subsidiaries, is an energy
delivery, products and services company with operations in New York,
Massachusetts, Maine, New Hampshire, Vermont and New Jersey, and offices in New
York and Connecticut. Energy East is the parent of New York State Electric & Gas
Corporation, a regulated public utility company. Energy East's nonutility
subsidiaries include XENERGY Enterprises, Inc. and Energy East Enterprises,
Inc., which invest in energy ventures and providers of energy-related and
telecommunication services.

    Energy East has adopted a strategy of selling its generation assets and
using a portion of the proceeds to grow selectively its energy distribution
business in the northeastern United States. Consistent with this strategy,
Energy East sold its coal-fired generation assets to Edison Mission Energy in
March 1999 and to The AES Corporation in May 1999. In addition, Energy East
expects to complete by early next year the sale of its 18% interest in Nine Mile
Point nuclear generating unit No. 2 to AmerGen Energy Company. The net cash
received from these sales is being used to repurchase Energy East shares and
will be used to help fund Energy East's business combinations with CTG
Resources, Connecticut Energy and CMP Group.

CTG RESOURCES (SEE PAGE 24)
CTG Resources, Inc.
P.O. Box 1500
100 Columbus Boulevard
Hartford, Connecticut 06144-1500
(860) 727-3000

    CTG Resources is a holding company whose businesses include the regulated
retail distribution of natural gas and other energy-related unregulated
activities. CTG Resources's principal subsidiary, Connecticut Natural Gas
Corporation, serves approximately 143,300 natural gas customers in Hartford,
Greenwich and 22 other cities and towns in central Connecticut. CTG Resources's
energy-related unregulated subsidiaries, including The Energy Network, Inc. and
The Hartford Steam Company, provide district heating and cooling services to
many buildings in Hartford and are involved in several cogeneration and other
ventures.

OAK MERGER CO. (SEE PAGE 24)
Oak Merger Co.
P.O. Box 1196
Stamford, Connecticut 06904-1196
(203) 325-0690

    Oak Merger Co. is a wholly owned subsidiary of Energy East, formed under the
laws of the State of Connecticut solely for the purpose of completing the merger
with CTG Resources.

                   THE SPECIAL MEETING (SEE PAGES 25 AND 26)

    The special meeting of CTG Resources shareholders will be held at the
offices of CTG Resources, 100 Columbus Boulevard, Hartford, Connecticut on
October 18, 1999, at 10:30 a.m. local time.

                                       5
<PAGE>
    At the special meeting, we will ask you to vote upon a proposal to approve
the merger agreement. Approval of the merger agreement requires the affirmative
vote of at least two-thirds of the outstanding CTG Resources shares.

    Only the CTG Resources shareholders at the close of business on the record
date, August 23, 1999, will be entitled to notice of and to vote at the special
meeting.

    Each CTG Resources share carries one vote. As of the close of business on
August 13, 1999, 8,648,029 CTG Resources shares were outstanding.

                  SHARE OWNERSHIP OF MANAGEMENT (SEE PAGE 70)

    On June 30, 1999, directors and executive officers of CTG Resources and
their affiliates beneficially owned approximately 1.5% of the outstanding CTG
Resources shares. It is expected that all of these directors and executive
officers will vote their shares FOR the approval of the merger agreement.

                                   THE MERGER

REASONS FOR AND BACKGROUND OF THE MERGER (SEE PAGES 28 TO 34)

    You should review the factors that the CTG Resources board of directors
considered when deciding whether to approve the merger.

RECOMMENDATION TO SHAREHOLDERS (SEE PAGES 34 TO 36)

    The CTG Resources board of directors has determined that the merger is in
the best interests of the CTG Resources shareholders and unanimously recommends
that CTG Resources shareholders vote to approve the merger agreement at the
special meeting.

FAIRNESS OPINION (SEE PAGES 36 TO 42)

    In deciding to approve the merger, the CTG Resources board of directors
considered, among other things, the opinion of PaineWebber Incorporated, its
financial advisor, as to the fairness, from a financial point of view, of the
consideration that CTG Resources shareholders will receive. This opinion is
attached as Appendix B to this document and is also discussed on pages 36 to 42.
We encourage you to read this opinion.

ACCOUNTING TREATMENT (SEE PAGE 43)

    The merger will be accounted for as an acquisition of CTG Resources by
Energy East under the purchase method of accounting in accordance with generally
accepted accounting principles. A portion of the purchase price will be
allocated to nonutility assets and liabilities of CTG Resources based on their
estimated fair market values at the date of acquisition. As a regulated utility,
the assets and liabilities of Connecticut Natural Gas will not be revalued. The
difference between the purchase price, representing fair value, and the recorded
amounts will be shown as goodwill on the balance sheet.

REGULATORY APPROVALS (SEE PAGES 43 TO 46)

    CTG Resources and Energy East must obtain regulatory approval from the
Connecticut Department of Public Utility Control. In addition, both companies
must file certain notification forms with the Antitrust Division of the
Department of Justice and the Federal Trade Commission. Finally, Energy East
must obtain Securities and Exchange Commission approval of the acquisition under
the Public Utility Holding Company Act and must either obtain an exemption from
registration under that Act or register with the Securities and Exchange
Commission as a holding company. Energy East expects that if it completes its
proposed merger with CMP Group, Energy East will no longer be eligible for this
exemption.

INTERESTS OF CERTAIN PERSONS IN THE MERGER (SEE PAGES 47 TO 50)

    In considering the recommendation of the CTG Resources board of directors to
approve the merger, CTG Resources shareholders should be aware that members of
the CTG Resources board of directors and CTG Resources management will receive
benefits as a result of the merger that will be in addition to or different from
the benefits that CTG Resources

                                       6
<PAGE>
shareholders receive generally. For example, Arthur C. Marquardt, current
chairman, president and chief executive officer of CTG Resources, will become
president and chief executive officer of the surviving company in the merger
(which will be a subsidiary of Energy East) and will hold officer positions in
other Energy East subsidiaries. In addition, one nonemployee director of CTG
Resources will become a director of Energy East, and members of the CTG
Resources board of directors will serve on an advisory board of the surviving
company.

    The members of the CTG Resources board of directors knew about these
additional interests and considered them when they approved the merger.

MATERIAL FEDERAL INCOME TAX CONSEQUENCES (SEE PAGES 50 TO 54)

    The U.S. federal income tax consequences of the merger to you will depend on
the form of consideration you receive in the merger. If you receive solely
Energy East shares for your CTG Resources shares, you will not recognize any
gain or loss for U.S. federal income tax purposes (except with respect to cash
received instead of fractional shares). If you receive part cash and part Energy
East shares, and your adjusted basis in your CTG Resources shares is less than
the sum of the amount of cash and the fair market value (as of the date of the
merger) of the Energy East shares you receive, you will recognize a gain. This
recognized gain will equal the lesser of (1) the sum of the amount of cash and
the fair market value, as of the date of the merger, of the Energy East shares
you receive, minus the adjusted basis of your CTG Resources shares, and (2) the
amount of cash you receive. However, if you realize a loss because your adjusted
basis in your CTG Resources shares is greater than the sum of the amount of cash
and the fair market value, as of the date of the merger, of the Energy East
shares you receive, the loss will not currently be allowed. If you receive
solely cash, gain or loss will generally be recognized by you to the extent of
the difference between the amount of cash you receive and your adjusted basis in
your CTG Resources shares.
    The consequences described above assume, as expected, that the merger will
qualify as a reorganization within the meaning of Section 368(a) of the Internal
Revenue Code.

    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.

                       DISSENTERS' RIGHTS OF APPRAISAL OF CTG
                             RESOURCES SHAREHOLDERS
                              (SEE PAGES 55 TO 57)

    Dissenters' rights of appraisal permit shareholders to receive cash in the
amount of the judicially determined fair value of their shares rather than the
consideration that they would receive in the transaction under the merger
agreement. Under Connecticut law, CTG Resources shareholders have dissenters'
rights of appraisal in the merger. Therefore, if you follow the procedures
required by Connecticut law and you dissent from the merger but the merger is
eventually approved by CTG Resources shareholders and completed, you will
receive a cash payment representing the judicially determined fair value of CTG
Resources shares you currently hold. You will not receive the consideration
payable under the merger agreement. The relevant provisions of Connecticut law
governing this process are attached as Appendix C to this document.

                              THE MERGER AGREEMENT

    The merger agreement is the legal document that governs the merger. The
merger agreement is attached as Appendix A to this document, and we encourage
you to read it carefully.

CONVERSION OF CTG RESOURCES SHARES (SEE
  PAGES 58 TO 61)

    In the merger, CTG Resources shareholders will have the option to elect to
receive either cash, Energy East shares or a combination of the two in return
for their shares, subject to limitations on the maximum and minimum number of
Energy East shares to be issued.

    Specifically, in exchange for each of their CTG Resources shares, CTG
Resources

                                       7
<PAGE>
shareholders will have the option to receive either $41.00 in cash or a number
of Energy East shares valued at $41.00, subject to restrictions on the maximum
and minimum number of Energy East shares to be issued. The number of Energy East
shares to be exchanged for each CTG Resources share will be between 1.3609 and
1.7320, based on the value of Energy East shares during the 20-trading-day
period ending two trading days before the effective time of the merger. CTG
Resources shareholders can choose to convert some of their CTG Resources shares
into cash and others into Energy East shares.

    Under the merger agreement, 55% of the CTG Resources shares must be
exchanged for cash, and 45% must be exchanged for Energy East shares. Therefore,
if CTG Resources shareholders owning more than 55% of the CTG Resources shares
elect to receive cash, the number of CTG Resources shares that will be converted
into cash will be less than the number elected. Similarly, if CTG Resources
shareholders owning more than 45% of the CTG Resources shares elect to receive
Energy East shares, the number of CTG Resources shares that will be converted
into Energy East shares will be less than the number elected.

CERTAIN COVENANTS (SEE PAGES 62 TO 64)

    CTG Resources has agreed not to solicit or encourage any proposal from any
person to acquire CTG Resources or its assets, but it may respond, in limited
circumstances, to unsolicited proposals that it receives.

CONDITIONS TO THE MERGER (SEE PAGES 67 TO 68)

    Completion of the merger depends upon satisfaction of a number of
conditions. In addition to customary conditions relating to our compliance with
the merger agreement, these conditions include the following:

    - approval of the merger agreement by CTG Resources shareholders;

    - approval of the merger by the Connecticut Department of Public Utility
      Control;

    - approval of the merger by the Securities and Exchange Commission under the
      Public Utility Holding Company Act;

    - expiration or termination of the waiting period applicable to the merger
      under U.S. federal antitrust laws and obtaining any other regulatory
      approvals;

    - absence of any injunction or legal restraint blocking the merger, or of
      any proceedings by a governmental authority to block the merger;

    - the Securities and Exchange Commission declaring effective, and the
      absence of a suspension by the Securities and Exchange Commission of the
      effectiveness of, the registration statement with respect to the Energy
      East shares to be issued in the merger;

    - the New York Stock Exchange approving for listing the Energy East shares
      to be issued in the merger; and

    - attorneys for Energy East furnishing to Energy East, and attorneys for CTG
      Resources furnishing to CTG Resources, opinions to the effect that the
      merger will be treated as a reorganization within the meaning of Section
      368(a) of the Internal Revenue Code.

    The merger will occur, and your CTG Resources shares will be converted into
the right to receive Energy East shares, cash or a combination of the two, as
soon as practicable after CTG Resources and Energy East satisfy all of the
conditions in the merger agreement.

TERMINATION (SEE PAGES 69 TO 70)

    The merger agreement may be terminated, and the merger abandoned, only in
the following circumstances:

    - if Energy East and CTG Resources mutually agree to terminate the merger
      agreement;

    - by either Energy East or CTG Resources if any law or regulation prohibits
      the merger, or if a court issues a final, non-appealable order blocking
      the merger;

    - by either Energy East or CTG Resources, if the merger is not completed by
      June 29, 2000 (or December 29, 2000, if the only barrier to closing is
      that the requisite regulatory approvals have not been obtained);

                                       8
<PAGE>
    - by either Energy East or CTG Resources, if the other party materially
      breaches the merger agreement and fails to cure the breach;

    - by Energy East, if the CTG Resources board of directors withdraws its
      approval of the merger agreement, fails to reaffirm its approval of the
      merger agreement upon Energy East's request, approves a competing
      acquisition proposal or resolves to take any of these actions; or

    - by CTG Resources, prior to its shareholders' approval of the merger
      agreement, if CTG Resources receives a third-party proposal concerning
      another merger, sale of substantial assets or other business combination,
      in response to which the CTG Resources board of directors determines,
      based on the advice of outside counsel, that failure to accept the
      proposal would likely result in a breach of its members' fiduciary duties,
      and concludes in good faith that the person making the alternative
      proposal has obtained or can obtain any necessary financing and that such
      proposal would be financially superior to the merger; provided that before
      CTG Resources can terminate the merger agreement, it must comply with
      additional conditions contained in the merger agreement discussed on page
      69.

    If either Energy East or CTG Resources materially breaches the merger
agreement and the other party consequently terminates the agreement, the
breaching party must pay the other party up to $4 million in expenses and fees.
Moreover, if the merger agreement is terminated for any of the following
reasons:

    - the CTG Resources board of directors decides to pursue an alternative
      acquisition proposal;

    - (1) CTG Resources shareholders fail to approve the merger agreement by
      June 29, 2000, (2) there is an alternative acquisition proposal
      outstanding at the time of the special meeting and (3) CTG Resources
      enters into a definitive agreement on or completes an alternative
      acquisition within two years of the termination of the merger agreement;
      or

    - (1) the CTG Resources board of directors withdraws, modifies or fails to
      affirm its approval of the merger agreement, (2) there is an alternative
      acquisition proposal outstanding at the time of the termination of the
      merger agreement and (3) CTG Resources enters into a definitive agreement
      on or completes an alternative acquisition within two years of the
      termination;

then CTG Resources must pay Energy East $14 million in addition to fees and
expenses up to $4 million. However, if the breach is willful, the merger
agreement does not limit the amount of damages, expenses and fees the
nonbreaching party may seek.

                              (SEE PAGES 92 TO 98)

    If you receive Energy East shares in the merger, your rights as an Energy
East shareholder will be governed by New York law and by Energy East's
certificate of incorporation and by-laws. These rights differ in certain
respects from your current CTG Resources shareholder rights, which are governed
by Connecticut law and CTG Resources's certificate of incorporation and by-laws.

    Energy East paid a dividend on Energy East shares of $.21 per share on
August 15, 1999, to holders of record on July 26, 1999. Energy East anticipates
that it will continue to pay quarterly cash dividends. The Energy East board of
directors, however, has discretion to decide upon the timing and

                                       10
<PAGE>
amount of any future dividends. Whether or not Energy East will pay dividends,
and, if so, how much these dividends will be, will depend on Energy East's
future earnings, financial condition, capital requirements and other factors.

    On July 27, 1999, the CTG Resources board of directors declared a dividend
on CTG Resources shares of $.26 per share, payable on September 24, 1999, to
holders of record on September 10, 1999. As part of the merger agreement, CTG
Resources has agreed that it will not make, declare or pay any dividend or
distribution on CTG Resources shares, other than regular quarterly dividends on
CTG Resources shares of $.26 per share with record and payment dates consistent
with past practice.

                 UNAUDITED PRO FORMA COMPARATIVE PER SHARE DATA

    We have summarized below information concerning earnings, cash dividends and
book value per share for:

    - each of Energy East and CTG Resources on a historical basis;

    - the combination of Energy East and CTG Resources on a pro forma basis;

    - CTG Resources on a per share equivalent pro forma basis based on the
      combination of Energy East and CTG Resources;

    - the combination of Energy East, CTG Resources, Connecticut Energy and CMP
      Group on a pro forma basis; and

    - CTG Resources on a per share equivalent pro forma basis based on the
      combination of Energy East, CTG Resources, Connecticut Energy and CMP
      Group.

    The pro forma information, in each case, takes into account Energy East's
sales of its generation assets. The pro forma information on the combination of
Energy East, CTG Resources, Connecticut Energy and CMP Group also takes into
account CMP Group's sale of its generation assets. We have derived the pro forma
combined earnings per share from the unaudited pro forma combined financial
statements presented elsewhere in this document. Book value per share for the
pro forma combined presentation is based upon outstanding Energy East shares,
adjusted to include the estimated number of Energy East shares to be issued in
the CTG Resources and Connecticut Energy mergers.

    The pro forma data are based on the assumed conversion of 45% of the CTG
Resources shares into 1.57 Energy East shares per CTG Resources share and 55%
into $41.00 in cash per CTG Resources share, and the assumed conversion of half
of the Connecticut Energy shares into 1.60 Energy East shares per Connecticut
Energy share and half into $42.00 in cash per Connecticut Energy share. We
calculated the exchange ratio for CTG Resources shares by dividing $41.00 by
$26.125, the closing price of Energy East shares on June 29, 1999. We calculated
the exchange ratio for Connecticut Energy shares by dividing $42.00 by $26.25,
the closing price of Energy East shares on April 22, 1999. The pro forma data
also reflect the fact that, in the CMP Group merger, CMP Group shareholders will
receive $29.50 in cash, and no Energy East shares, for each of their CMP Group
shares.

    You should read the information set forth below together with the audited
and unaudited financial statements of Energy East, CTG Resources, Connecticut
Energy and CMP Group incorporated by reference in this document and the
unaudited pro forma combined financial statements and related notes presented
elsewhere in this document. See "Where You Can Find More Information."

                         SELECTED FINANCIAL INFORMATION

    The following tables present (1) selected consolidated financial information
for each of Energy East, CTG Resources, Connecticut Energy and CMP Group on a
historical basis; (2) selected unaudited pro forma financial data for Energy
East reflecting the sales of its generation assets and the merger with CTG
Resources; and (3) selected unaudited pro forma financial data of Energy East
reflecting the sales of its generation assets, its mergers with CTG Resources,
Connecticut Energy and CMP Group and the sale of CMP Group's generation assets.

    We prepared the selected unaudited pro forma financial data by accounting
for the mergers with CTG Resources, Connecticut Energy and CMP Group under the
purchase method of accounting. See "The Merger -- Accounting Treatment." The CTG
Resources and Connecticut Energy twelve-month financial information is based on
a September 30 fiscal year. The selected unaudited pro forma financial data
reflect the mergers with CTG Resources, Connecticut Energy and CMP Group based
upon preliminary purchase accounting adjustments. Actual amounts may differ from
those reflected below.

    The selected historical financial data for Energy East and CMP Group as of
December 31, 1998, 1997, 1996, 1995 and 1994 and for each of the years in the
five-year period ended December 31, 1998, set forth below, have been derived
from Energy East's and CMP Group's audited financial statements. The selected
historical financial data for CTG Resources and Connecticut Energy as of
September 30, 1998, 1997, 1996, 1995 and 1994 and for each of the years in the
five-year period ended September 30, 1998, set forth below, have been derived
from CTG Resources's and Connecticut Energy's audited financial statements. The
selected historical financial data for Energy East, CTG Resources, Connecticut
Energy and CMP Group as of and for the six months ended June 30, 1999 and June
30, 1998, set forth below, have been derived from their unaudited financial
statements and, in the opinion of their managements, include all adjustments,
consisting of normal recurring adjustments, necessary for fair presentations of
the data of these periods.

    Due to the effect of seasonal fluctuations and other factors on the
operations of Energy East, CTG Resources, Connecticut Energy and CMP Group,
financial results for a period that is less than a full financial year are not
necessarily indicative of results for the full fiscal year. You should read the
information set forth below in conjunction with the respective audited and
unaudited financial statements of Energy East, CTG Resources, Connecticut Energy
and CMP Group incorporated by reference in this document and the unaudited pro
forma combined financial statements and related notes presented elsewhere in
this document. See "Where You Can Find More Information" and "Unaudited Pro
Forma Combined Condensed Financial Statements."

    The pro forma balance sheet data give effect to the sales of the generation
assets and to the mergers as if these events occurred as of the balance sheet
dates; the pro forma statement of income data give effect to the sales of the
generation assets and the mergers as if these events occurred on January 1,
1998. The pro forma financial data are not, however, necessarily indicative of
the financial position or operating results that would have occurred had the
sales of the generation assets and the mergers been completed on these dates;
nor is the information necessarily indicative of future financial position or
operating results.

                                  RISK FACTORS

    IN CONSIDERING WHETHER TO VOTE IN FAVOR OF THE MERGER AGREEMENT AND WHETHER
TO ELECT TO RECEIVE ENERGY EAST SHARES OR CASH FOR YOUR CTG RESOURCES SHARES,
YOU SHOULD CONSIDER ALL THE INFORMATION WE HAVE INCLUDED IN THIS PROXY
STATEMENT/PROSPECTUS AND ITS APPENDICES AND ALL THE INFORMATION INCLUDED IN THE
DOCUMENTS WE HAVE INCORPORATED BY REFERENCE. IN ADDITION, YOU SHOULD PAY
PARTICULAR ATTENTION TO THE FOLLOWING RISK FACTORS RELATED TO THE MERGER AND TO
ENERGY EAST. THESE FACTORS ARE IMPORTANT, AND WE HAVE NOT BEEN ABLE TO QUANTIFY
THEIR POTENTIAL EFFECTS ON THE COMBINED COMPANY THAT WILL RESULT FROM THE
MERGER.

THE AMOUNT OF CONSIDERATION SHAREHOLDERS RECEIVE MAY VARY AS A RESULT OF
  STOCK-PRICE FLUCTUATIONS PRIOR TO THE COMPLETION OF THE MERGER

    Although CTG Resources shareholders will be able to elect to exchange their
CTG Resources shares for either cash or Energy East shares (or a combination of
cash and Energy East shares), the opportunity to make that election will not
occur at the time of the shareholder vote on the merger. Instead, it will occur
shortly after the effective time of the merger (as described further in this
proxy statement/prospectus), after all necessary regulatory approvals have been
obtained. The cash price per share to be paid for CTG Resources shares is fixed
at $41.00. This price will not be adjusted based on changes in market prices.
The value of Energy East shares delivered to CTG Resources shareholders will
equal $41.00 if the average market price of an Energy East share over the
20-trading-day period ending two trading days before the effective time of the
merger is between $23.67 and $30.13. However, if the average market price of an
Energy East share over such period is more than $30.13 or less than $23.67, the
value of the Energy East shares delivered to holders of CTG Resources shares
would be more than or less than $41.00.

    There may be a significant time delay between the date when CTG Resources
shareholders vote on the merger agreement at the special meeting and the
deadline for CTG Resources shareholders to make their elections, which is two
days after the effective time of the merger. The market values of Energy East
shares and CTG Resources shares may fluctuate during that period. As a result,
the relative prices of Energy East shares and CTG Resources shares may vary
significantly between the date of this proxy statement/prospectus, the date of
the special meeting and the date on which CTG Resources shareholders will have
the opportunity to make their elections. These variances may be caused by
changes in the businesses, operations, results and prospects of both companies,
market expectations of the likelihood that the merger will be completed and the
timing of completion, the effect of any conditions or restrictions imposed on or
proposed with respect to the combined company by regulatory agencies, general
market and economic conditions, or other factors.

    For example, between June 29, 1998, and June 29, 1999, the closing sales
price of an Energy East share has ranged from a high of $29 to a low of $20 per
share, and the closing sales price of a CTG Resources share during the same
period has ranged from a high of $35.63 to a low of $22.38 per share. On August
13, 1999, the most recent date for which it was practicable to obtain market
price data, (1) the closing sales price of Energy East shares was $25.69, and
(2) the closing sales price of CTG Resources shares was $36.25, as reported in
THE WALL STREET JOURNAL's New York Stock Exchange Composite Transactions. We
urge you to obtain current market quotations for Energy East shares and CTG
Resources shares. In addition, the stock market generally has experienced
significant price and volume fluctuations. These market fluctuations could have
a material adverse effect on the market for, or liquidity of, Energy East shares
and CTG Resources shares.

    It is impossible to predict accurately the market price of Energy East
shares immediately after the effective time of the merger and, therefore,
impossible to predict accurately the value of the stock consideration that CTG
Resources shareholders will receive. The value of the stock consideration may be
significantly higher or lower than the value of the cash consideration. See

Pro Forma Comparative Per Share Data" and "-- Comparative Per Share Market Price
and Dividend Information."

REGULATORY AGENCIES COULD DELAY OR REFUSE TO APPROVE THE MERGER OR IMPOSE
  CONDITIONS THAT COULD HAVE AN ADVERSE EFFECT

    To complete the merger, CTG Resources and Energy East must obtain approvals
or consents from state and federal regulatory agencies, including the
Connecticut Department of Public Utility Control and the Securities and Exchange
Commission. The state or federal regulatory agencies may impose conditions that
could have an adverse effect on the business or financial position of CTG
Resources or Energy East. If these conditions would cause a material adverse
effect, either CTG Resources or Energy East could choose to terminate the merger
agreement.

    In addition to the merger agreement with CTG Resources, Energy East has
entered into merger agreements with Connecticut Energy and CMP Group. Energy
East must obtain the Connecticut Department of Public Utility Control's approval
of the Connecticut Energy merger and the Securities and Exchange Commission's
approval of the Connecticut Energy and CMP Group mergers; furthermore, the Maine
Public Utilities Commission must approve the CMP Group merger. These regulatory
authorities could delay approval of or impose burdensome conditions on the
Connecticut Energy and CMP Group mergers. Although the completion of the CTG
Resources merger is not conditioned upon obtaining regulatory approvals of the
other two mergers, any delay in obtaining the required regulatory approvals of
the other two mergers could delay and possibly prevent the realization of
benefits of the combined company that would include Energy East, CTG Resources,
Connecticut Energy and CMP Group. Furthermore, any burdensome regulatory
conditions could have an adverse effect upon the combined company and its share
performance. We cannot be certain that all of the required regulatory approvals
will be obtained, or that they will be obtained within the time frame
contemplated by the merger agreement or that they will be obtained without
burdensome conditions. For additional information on the required regulatory
approvals, see "The Merger -- Regulatory Approvals."

UNCERTAINTIES IN INTEGRATING ENERGY EAST, CTG RESOURCES, CONNECTICUT ENERGY AND
  CMP GROUP

    The mergers of Energy East with CTG Resources, Connecticut Energy and CMP
Group will require the integration of four companies that have previously
operated independently. No assurance can be given that Energy East will be able
to integrate the operations of these companies without encountering difficulties
or experiencing the loss of key employees, customers or suppliers. Energy East's
management will have to dedicate substantial time and effort to ensure that this
integration proceeds successfully.

COMPETITIVE AND REGULATORY CONDITIONS

    The mergers will combine companies that to a large extent share a common
regulatory environment and currently are affected by a number of similar
factors, including deregulation and increased competition. The utility industry
has been undergoing dramatic structural change for several years, resulting in
increasing competitive pressures faced by electric and natural gas utility
companies. Increased competition may create greater risks to the stability of
utility earnings generally and may in the future reduce Energy East's earnings
from retail electric and natural gas sales. In a deregulated environment,
formerly regulated utility companies that are not responsive to a competitive
energy marketplace may suffer erosion in market share, revenues and profits as
competitors gain access to their service territories.

YEAR-2000 READINESS DISCLOSURE STATEMENT

    CTG Resources, Energy East, Connecticut Energy and CMP Group are each
engaged in major company-wide efforts to address the year-2000 issue. This issue
relates to the inability of some computer programs and computer chips embedded
in operating equipment to recognize properly dates during and after the year
2000. This could result in system failures or miscalculations that could cause
disruptions to various business activities and operations. CTG Resources, Energy
East, Connecticut Energy and CMP Group expect to complete their efforts to
address the year-2000 issues in advance of December 31, 1999, and each is
planning to take steps to deal with possible year-2000 issues that may arise
around that date. However, factors that could cause actual results to differ
materially from those contemplated in this proxy statement/prospectus include,
among others:

    - the risk that more year-2000 issues may be found;

    - the risk that progress in addressing year-2000 issues may not proceed as
      expected;

    - the fact that despite all efforts, there can be no assurances that all
      year-2000 issues can or will be remedied;

    - the fact that there can be no assurances that all year-2000 issues will be
      totally eliminated by suppliers, customers, neighboring or interconnected
      utilities and other entities; and

    - the fact that assessments of the effects of year-2000 issues are based, in
      part, upon information received from suppliers, customers, neighboring or
      interconnected utilities and other entities, and this information may be
      inaccurate or incomplete.

                                 THE COMPANIES

ENERGY EAST

P.O. Box 1196
Stamford, CT 06904-1196
(203) 325-0690

    Energy East is a New York corporation that was formed in 1997 and became the
parent of New York State Electric & Gas Corporation ("NYSEG") on May 1, 1998.
Energy East is a holding company that is currently exempt from the registration
requirement of the Public Utility Holding Company Act. Energy East expects that
if the pending merger with CMP Group is completed, it will no longer be eligible
for this exemption, and has agreed that it will register with the Securities and
Exchange Commission as a public utility holding company. It neither owns nor
operates any physical properties. Energy East, through its subsidiaries, is an
energy delivery, products and services company with operations in New York,
Massachusetts, Maine, New Hampshire, Vermont and New Jersey, and has offices in
New York and Connecticut. Energy East's nonutility subsidiaries include XENERGY
Enterprises, Inc. and Energy East Enterprises, Inc., which invest in energy
ventures and providers of energy and telecommunication services.

    NYSEG.  NYSEG, Energy East's principal subsidiary, is a public utility
company engaged in purchasing, transmitting and distributing electricity, and
purchasing, transporting and distributing natural gas. NYSEG also generates
electricity from its 18% share of a nuclear station and its hydroelectric
stations. NYSEG has agreed to sell its share of the nuclear station; the sale is
expected to be completed by early next year. NYSEG's service territory, 99% of
which is located outside the corporate limits of cities, is in the central,
eastern and western parts of the State of New York. NYSEG's service territory
has an area of approximately 19,900 square miles and a population of 2,400,000.
The larger cities in which NYSEG serves both electricity and natural gas
customers are Binghamton, Elmira, Auburn, Geneva, Ithaca and Lockport. NYSEG
serves approximately 826,000 electric customers and 244,000 natural gas
customers. The service territory reflects a diversified economy, including
high-tech firms, light industry, colleges and universities, agriculture and
recreational facilities. No customer accounts for 5% or more of either electric
or natural gas revenues. During 1996 through 1998, approximately 84% of NYSEG's
operating revenue was derived from electric service with the balance derived
from natural gas service.

    XENERGY ENTERPRISES, INC.  XENERGY Enterprises is a nonutility subsidiary of
Energy East and invests in providers of energy and telecommunications services.
One of XENERGY's subsidiaries is XENERGY Inc., which provides energy services,
information systems and energy consulting to utilities, governmental agencies,
and end-use energy consumers, primarily commercial and industrial.

    Another one of XENERGY's subsidiaries, Energy East Solutions, Inc., markets
electricity and natural gas to end-use customers and wholesale markets in the
northeastern United States directly and through its wholly owned subsidiary,
NYSEG Solutions, Inc. In October 1998, Energy East Solutions formed a joint
venture with South Jersey Industries to market retail electricity and energy
management services in the mid-Atlantic region of the United States.

    ENERGY EAST ENTERPRISES, INC.  Energy East Enterprises, another Energy East
subsidiary, owns natural gas and propane air distribution companies outside of
the State of New York. Energy East Enterprises owns an interest in CMP Natural
Gas, L.L.C., which was formed to distribute natural gas to customers in Maine
who do not receive natural gas service and which began to provide service to
customers in May 1999. CMP Natural Gas, a Maine limited liability company, is
jointly owned by Energy East Enterprises and New England Gas Development
Corporation, a wholly owned subsidiary of CMP Group.

                                       22
<PAGE>
    New Hampshire Gas Corporation, another subsidiary of Energy East
Enterprises, established a presence in New Hampshire with the purchase of a
franchise and propane air distribution system. Long-term plans call for bringing
natural gas to this area.

    Southern Vermont Natural Gas Corporation, a third subsidiary of Energy East
Enterprises, is working with Iroquois Gas Transmission System and Vermont Energy
Park Holdings to develop a combined natural gas supply and electric generation
project that includes an extension of a pipeline from New York to Vermont, two
combined-cycle electric generating plants and natural gas distribution systems.

    SALE OF GENERATION ASSETS.  Energy East has adopted a strategy of selling
its generation assets and using a portion of the proceeds to grow selectively
its energy distribution business in the northeastern United States. Consistent
with this strategy, Energy East sold its coal-fired generation assets to Edison
Mission Energy in March 1999 and to The AES Corporation in May 1999. In
addition, Energy East expects to complete by early next year the sale of its 18%
interest in Nine Mile Point nuclear generating unit No. 2 to AmerGen Energy
Company. The net cash received from these sales is being used to repurchase
Energy East shares and will be used to help fund Energy East's business
combinations with CTG Resources, Connecticut Energy and CMP Group.

    MERGER AGREEMENT WITH CONNECTICUT ENERGY.  On April 23, 1999, Energy East
agreed to a business combination with Connecticut Energy, in which Connecticut
Energy would merge with a newly formed, wholly owned subsidiary of Energy East.
In the transaction, Connecticut Energy shareholders will have the right to
receive, for each of their Connecticut Energy shares, either $42.00 in cash or a
number of Energy East shares valued at $42.00, subject to restrictions on the
maximum and minimum number of Energy East shares to be issued. Connecticut
Energy shareholders can choose to convert some of their Connecticut Energy
shares into cash and others into Energy East shares. The total equity market
value of the transaction is approximately $436 million. Under the Connecticut
Energy merger agreement, the Energy East board of directors will increase the
number of Energy East directors by one and will elect Mr. J.R. Crespo to its
board of directors. Completion of the transaction is subject to a number of
closing conditions, including regulatory approvals and Connecticut Energy
shareholder approval.

    Connecticut Energy's wholly owned utility subsidiary, The Southern
Connecticut Gas Company, serves approximately 158,000 customers in Connecticut.
For additional information on this transaction, see "Unaudited Pro Forma
Combined Condensed Financial Statements," the Connecticut Energy merger
agreement (a copy of which Energy East filed with the SEC as an exhibit to its
Form 8-K dated April 23, 1999) and the Energy East registration statement on
Form S-4 dated July 22, 1999.

    MERGER AGREEMENT WITH CMP GROUP.  On June 14, 1999, Energy East agreed to a
business combination with CMP Group, in which CMP Group would merge with a newly
formed, wholly owned subsidiary of Energy East. In the transaction, CMP Group
shareholders will have the right to receive $29.50 in cash, without interest,
for each of their CMP Group shares. The total equity market value of the
transaction is approximately $957 million. Under the CMP Group merger agreement,
the Energy East board of directors will increase the number of Energy East
directors by three and will elect Mr. David T. Flanagan (the current president
and chief executive officer of CMP Group) and two other directors of CMP Group
mutually agreed upon by Energy East and CMP Group. Completion of the transaction
is subject to a number of closing conditions, including regulatory approvals and
CMP Group shareholder approval.

    CMP Group's wholly owned utility subsidiary, Central Maine Power Company,
serves approximately 530,000 customers in central and southern Maine. For
additional information on this transaction, see "Unaudited Pro Forma Combined
Condensed Financial Statements" and the CMP Group merger agreement, a copy of
which Energy East filed with the SEC as an exhibit to its Form 8-K dated June
14, 1999.

                              THE SPECIAL MEETING

PURPOSE, TIME AND PLACE

    The CTG Resources board of directors is soliciting proxies in the form
accompanying this proxy statement/prospectus for use at the special meeting of
CTG Resources shareholders. The special meeting will be held on October 18,
1999, at 10:30 a.m. local time, at the offices of CTG Resources, 100 Columbus
Boulevard, Hartford, Connecticut. Except as otherwise noted, when we refer in
this proxy statement/prospectus to the special meeting, we are including any
adjournments or postponements of that special meeting.

    At the special meeting, CTG Resources shareholders as of the record date
will be asked to consider and vote on a proposal to approve the merger
agreement.

RECORD DATE, VOTING POWER AND VOTE REQUIRED

    The CTG Resources board of directors has fixed the close of business (5:00
p.m. local time) on August 23, 1999 as the record date for determining the CTG
Resources shareholders entitled to notice of, and to vote at, the special
meeting. Only CTG Resources shareholders of record at the close of business on
the record date will be entitled to notice of, and to vote at, the special
meeting.

    At the close of business on August 13, 1999, 8,648,029 CTG Resources shares
were issued and outstanding. There were no shares of CTG Resources preferred
stock issued and outstanding. CTG Resources shareholders of record are entitled
to one vote per share on the merger agreement. Votes may be cast at the special
meeting in person or by proxy. See "--Voting of Proxies."

    The presence at the special meeting, either in person or by proxy, of the
holders of a majority of the outstanding CTG Resources shares entitled to vote
is necessary to constitute a quorum. If a quorum is not present at the special
meeting, CTG Resources management will adjourn or postpone the meeting in order
to solicit additional proxies.

    The affirmative vote of the holders of at least two-thirds of the
outstanding CTG Resources shares is required to approve the merger agreement.

    Abstentions and properly executed broker non-votes (that is, shares held by
brokers as nominees as to which instructions have not been received from the
beneficial owners 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 and will not be counted for the purposes of determining whether the
merger agreement has been approved. Abstentions and properly executed broker
non-votes will have the effect of a vote against the merger agreement.

SHARE OWNERSHIP OF MANAGEMENT

    At the close of business on June 30, 1999, CTG Resources's directors and
executive officers and their affiliates beneficially owned 133,731 CTG Resources
shares, which represents approximately 1.5% of the outstanding CTG Resources
shares. It is currently expected that all directors and executive officers of
CTG Resources will vote their CTG Resources shares for approval of the merger
agreement.

VOTING OF PROXIES

    CTG Resources shares represented by properly signed and dated proxies
received in time for the special meeting will be voted at the special meeting in
the manner specified by the proxies. You may also vote your shares by appointing
and directing your proxies by telephone in accordance with the instructions on
the proxy card. You should be aware that, if your proxy is properly signed and
dated but

                                       25
<PAGE>
does not contain voting instructions, your proxy will be voted FOR the approval
of the merger agreement. If you vote your CTG Resources shares by telephone,
your shares will be voted at the special meeting as instructed. Only the
approval of the merger agreement and possibly procedural items relating to the
conduct of the special meeting will be brought before the special meeting. Under
Connecticut law, the only business that may be conducted at a special meeting is
the business within the purposes described in the meeting notice.

    If you participate in the CTG Resources Dividend Reinvestment Plan, and you
own uncertificated shares, your proxy card represents both the number of CTG
Resources shares certificated in your name and the number of full CTG Resources
shares credited to your account, unless the registrations are different. If you
have CTG Resources 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 or the instructions received
by telephone. If your shares are held by a broker as nominee, you will receive a
voter information form from your broker.

    The grant of a proxy does not preclude you from voting in person.

REVOCABILITY OF PROXIES

    You may revoke a proxy at any time before its exercise by (1) notifying in
writing the Secretary of CTG Resources at CTG Resources, Inc., P.O. Box 1500,
100 Columbus Boulevard, Hartford, Connecticut 06144-1500, Attention: Secretary,
(2) completing a later-dated proxy and returning it to the Secretary of CTG
Resources or (3) appearing in person and voting at the special meeting.
Additional proxy cards are available from CTG Resources's Secretary.

    Attendance at the special meeting will not by itself constitute revocation
of a proxy. A CTG Resources shareholder of record attending the special meeting
may revoke his proxy and vote in person by informing any of the persons named on
the enclosed proxy card that he desires to revoke a previously submitted proxy.

    We do not expect to adjourn the special meeting for a period of time long
enough to require the setting of a new record date for the special meeting. If
an adjournment occurs, it will have no effect on the ability of the CTG
Resources shareholders of record as of the record date either to exercise their
voting rights or to revoke any previously granted proxies.

SOLICITATION OF PROXIES

    We will bear the costs of soliciting proxies from CTG Resources
shareholders, except that Energy East and CTG Resources intend to share equally
the costs associated with the printing and filing of this proxy
statement/prospectus. In addition to solicitation by mail, the directors,
officers and employees of CTG Resources and its subsidiaries may solicit proxies
from CTG Resources shareholders 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 solicitation
of proxies. Arrangements will also be made with brokerage houses and other
custodians, nominees and fiduciaries for the forwarding of solicitation material
to the beneficial owners of CTG Resources shares held of record by these
persons, and CTG Resources will reimburse its custodians, nominees and
fiduciaries for their reasonable out-of-pocket expenses.

    We have retained D.F. King & Co., Inc. to help solicit proxies. D.F. King &
Co. will receive a fee that we expect will not exceed $13,000 as compensation
for its basic solicitation services, plus additional charges for any telephone
solicitation services, plus reimbursement of its out-of-pocket expenses. CTG
Resources has agreed to indemnify D.F. King & Co. against certain liabilities
arising from its engagement.

    YOU SHOULD NOT SEND STOCK CERTIFICATES WITH YOUR PROXY CARDS.

                                       26
<PAGE>
                 NO VOTE REQUIRED FOR ENERGY EAST SHAREHOLDERS

    Under New York law, Energy East shareholders need not approve the merger
agreement. Thus, no one is soliciting proxies from Energy East shareholders.

                                       27
<PAGE>
                                   THE MERGER

    We are furnishing this proxy statement/prospectus to you in connection with
the proposed merger between Oak Merger Co. and CTG Resources because you are a
CTG Resources shareholder. If completed, the merger will be carried out as
provided in the merger agreement, a copy of which is attached as Appendix A to
this proxy statement/prospectus.

GENERAL DESCRIPTION OF THE MERGER

    The merger agreement provides that CTG Resources will merge into Oak Merger
Co., a wholly owned subsidiary of Energy East. Oak Merger Co. will be the
surviving company and will continue to conduct CTG Resources's businesses under
the name "CTG Resources, Inc." as a direct, wholly owned subsidiary of Energy
East. In the merger, each outstanding CTG Resources share (other than those that
are held by CTG Resources shareholders who have not voted in favor of the merger
and have properly demanded dissenters' rights) will be converted into the right
to receive cash or Energy East shares. CTG Resources shareholders can choose to
convert some of their CTG Resources shares into cash and others into Energy East
shares.

    Each CTG Resources shareholder can elect the form of consideration he would
like to receive, but (as is explained under "The Merger Agreement -- Conversion
of CTG Resources Shares") this election is subject to proration and an
adjustment driven by tax considerations. Under the merger agreement, 55% of all
issued and outstanding CTG Resources shares must be exchanged for cash, and 45%
must be exchanged for Energy East shares. If CTG Resources shareholders owning
more than 55% of CTG Resources shares elect to receive cash, the number of CTG
Resources shares converted into cash will be less than the number elected.
Similarly, if CTG Resources shareholders owning more than of 45% of CTG
Resources shares elect to receive Energy East shares, the number of CTG
Resources shares converted into stock will be less than the number elected. For
tax reasons that are explained below, Energy East may have to increase the
number of CTG Resources shares converted into Energy East shares and decrease
the number of CTG Resources shares converted into cash.

    The per share cash consideration amounts to $41.00 in cash, without
interest. The per share stock consideration is a number of Energy East shares
that will vary depending on the "AVERAGE MARKET PRICE," which is the average of
the closing prices of Energy East shares on the New York Stock Exchange during
the 20 trading days immediately preceding the second trading day prior to the
effective time of the merger. If the Average Market Price is between $23.67 per
share and $30.13 per share, then each CTG Resources share converted into stock
will be exchanged for $41.00 worth of Energy East shares. If the Average Market
Price is less than or equal to $23.67, then each CTG Resources share converted
into stock will be exchanged for 1.7320 Energy East shares, irrespective of the
value of those shares. Finally, if the Average Market Price is greater than or
equal to $30.13 per share, then each CTG Resources share will be exchanged for
1.3609 Energy East shares, again irrespective of the value of those shares.

    The total value of the consideration that CTG Resources shareholders will
receive in the merger, based on the number of CTG Resources shares outstanding
on August 13, 1999 and assuming that the Average Market Price of Energy East
shares is between $23.67 per share and $30.13 per share, is approximately $354.6
million.

BACKGROUND

    Energy East has recently taken major steps in refocusing its business on
energy distribution. It is evolving from a vertically integrated upstate New
York utility to a growing energy distribution and services company in the
northeastern United States. In 1998, it accepted offers totaling $1.85 billion
for the sale of its coal-fired generation assets. Those sales have now been
completed. In addition, Energy

                                       28
<PAGE>
East expects to complete by early next year the sale of its 18% interest in Nine
Mile Point nuclear generating unit No. 2 to AmerGen Energy Company. The net cash
received from the sales is being used to repurchase Energy East shares and will
be used to grow selectively Energy East's energy distribution business in the
northeastern United States. The merger with CTG Resources, together with the
recently announced proposed mergers with Connecticut Energy and CMP Group,
represent important steps in Energy East's overall strategy.

    CTG Resources has carefully followed recent developments in the electric and
gas utility industries that have substantially increased competition in those
industries, making it particularly difficult for the small and medium-sized
utility companies to compete as effectively as larger utilities. Over the past
several years, CTG Resources has developed strategic plans to respond to the
evolving competitive environment as it affected CTG Resources. CTG Resources's
management concluded that the company's competitive position and growth
prospects would be significantly enhanced by, among other things, increasing the
scale of its operations and the size of its customer base, as well as an
increased focus on complementary nonutility activities. As a result, from time
to time, Arthur C. Marquardt, the chairman, president and chief executive
officer of CTG Resources, had conversations with chief executive officers of
other utilities considering the strategic direction of the utility industry and
business combinations in general.

    In June 1998, CTG Resources's management conducted preliminary analyses of a
possible business combination with a neighboring company with gas utility
operations of similar size to those of CTG Resources's gas utility operations.
Although from time to time from July 1998 through September 1998 members of
senior management and the boards of directors of the two companies and the two
companies' respective financial advisors had exploratory conversations about the
possibility of a business combination, none of these conversations led to any
substantive negotiations.

    As a result of the commencement of those conversations, however, on or about
June 25, 1998, CTG Resources engaged PaineWebber to provide financial advisory
services and to act as financial advisor in connection with a possible business
combination involving CTG Resources.

    At a meeting of the CTG Resources board of directors in September 1998,
PaineWebber made a presentation to the board describing recent business
combination activity within the utility industry both regionally and nationally.
At that meeting, outside legal counsel explained the duties of the board when
considering possible business combination transactions.

    From time to time from September 1998 through February 1999, Mr. Marquardt
had exploratory conversations with executives at various other regional utility
companies about the possibility of a business combination or other strategic
transaction, but none of these conversations led to any substantive
negotiations. During this period, members of CTG Resources's senior management
and representatives of PaineWebber also had conversations with a company
operating a large electric and gas utility system in the mid-Atlantic region of
the United States about joint ventures involving gas utility and limited
nonutility operations and about a possible business combination transaction.
Although a confidentiality agreement was signed and limited information was
exchanged, none of these conversations led to any substantive negotiations.

    In November 1998, in connection with an economic development project in
Hartford, Connecticut, the Governor of the State of Connecticut announced that
he had reached agreement with the owner of the New England Patriots football
team under which the team would move to Connecticut and play its home games at a
newly built stadium in Hartford. The proposed site for the stadium was located
on the current site of CTG Resources's executive offices and a CTG Resources
steam plant. From time to time from December 1998 through February 1999, CTG
Resources had conversations with various representatives of the State of
Connecticut regarding the relocation of the executive offices and steam plant
and the appropriate level of compensation for that relocation.

                                       29
<PAGE>
    On or about February 3, 1999, Mr. Marquardt had a discussion with the
chairman, president and chief executive officer of a company operating an
electric utility system considerably larger than CTG Resources. During that
conversation, they discussed their respective companies' business strategies and
the possibility of a business combination.

    On February 23, 1999, Mr. Marquardt received a letter from the chairman of
the other company indicating that it remained interested in pursuing the
business combination transaction that Mr. Marquardt and the chairman discussed
on February 3, 1999. On February 24, 1999, Mr. Marquardt wrote a letter to the
chairman and indicated that CTG Resources was not interested in exploring the
possibility of a transaction; in the letter Mr. Marquardt cited concern with the
State of Connecticut's attempt to develop a football stadium on a site in
Hartford that includes CTG Resources's headquarters, gas operations center and
other facilities.

    On March 3, 1999, the chairman of the other company telephoned Mr. Marquardt
and reiterated his company's interest in pursuing a transaction. He stated his
belief that the two companies could reach an agreement with the State of
Connecticut with respect to the stadium project issue as part of an overall
agreement on a business combination transaction. There were no negotiations
involving price. The chairman indicated, however, that his company would be
willing to make a proposal that would provide CTG Resources shareholders with a
per share consideration in the lower part of the $30 to $40 range. Mr. Marquardt
indicated that he would discuss the expressed interest with the executive
committee of the CTG Resources board of directors at a meeting scheduled for
March 10, 1999. On March 5, 1999, Mr. Marquardt received a letter from the
chairman of the other company that confirmed the oral proposal of March 3, 1999.

    On March 9, 1999, Mr. Marquardt met with the chairman of the other company
during which they began to discuss the potential benefits of a possible business
combination. The executive committee of the CTG Resources board of directors was
advised of these discussions at a special meeting held on March 10, 1999. CTG
Resources's financial advisor and outside legal counsel were present at that
meeting. Outside legal counsel again outlined the nature of the directors'
duties in the context of a possible business combination. The executive
committee concluded that the matter should be submitted to the full CTG
Resources board of directors.

    From March 11, 1999 through March 18, 1999, there were further discussions
involving Mr. Marquardt, the chairman of the other company, members of the
boards of directors of the two companies and the two companies' financial
advisors.

    The CTG Resources board of directors was advised of these discussions at its
regularly scheduled meeting held on March 23, 1999. At that meeting, Mr.
Marquardt stated that, although the other company was a candidate to provide the
growth previously determined to be essential to shareholder value in the rapidly
changing utility industry, he did not know whether that company was willing or
able to enter into an agreement that would provide CTG Resources shareholders
with consideration comparable to that received by shareholders of other gas
distribution companies in comparable transactions. Representatives of
PaineWebber followed Mr. Marquardt's presentation with a discussion of recent
comparable transactions. Following these presentations, the CTG Resources board
of directors authorized management to continue discussions with the other
company regarding a possible business combination.

    On March 23, 1999, following the meeting of the CTG Resources board of
directors, there were further discussions involving Mr. Marquardt, the chairman
of the other company and the boards of directors of the two companies.
Representatives from the financial advisors of the two companies also
participated in the meeting. At the meeting, the other company submitted a
business combination proposal that would have provided CTG Resources
shareholders with a per share consideration in the middle of the $30 to $40
range. Mr. Marquardt indicated that he did not believe this proposal provided

                                       30
<PAGE>
adequate consideration to CTG Resources shareholders. The other company
expressed an unwillingness to increase its offer and discussions between the two
companies ceased.

    In April and May of 1999, Mr. Marquardt had exploratory discussions with
executive officers at other utility companies about the possibility of a
business combination or other strategic transaction. Mr. Marquardt's discussions
with these companies resulted in one company, which was substantially larger
than CTG Resources, entering into a confidentiality agreement with CTG
Resources. Confidential information was exchanged and the two companies
conducted business and legal due diligence. The financial advisors for both
companies also met and discussed terms of a possible transaction. The other
company submitted a business combination proposal in May 1999 that would have
provided CTG Resources shareholders with a per share consideration in the upper
part of the $30 to $40 range in the form of a combination of the other company's
stock and cash.

    On May 13, 1999, at a telephonic meeting of the CTG Resources board of
directors, CTG Resources's senior management and representatives of PaineWebber
briefed the CTG Resources board of directors with regard to this business
combination proposal. The CTG Resources board of directors authorized Mr.
Marquardt and other members of senior management to continue discussions
regarding that business combination. The CTG Resources board of directors was
briefed about the possible business combination proposal at another telephonic
meeting held on May 21, 1999. The CTG Resources board of directors again
authorized Mr. Marquardt and other members of senior management to continue
discussions regarding that business combination proposal.

    On May 25, 1999, CTG Resources management and financial advisors made
presentations to the CTG Resources board of directors relating to the
transaction. Outside legal counsel again explained the directors' duties in this
type of transaction and outlined the terms of a proposed merger agreement, which
had been sent to the board in advance of the meeting. The CTG Resources board of
directors authorized management to negotiate an acceptable transaction with the
other company. After several days of negotiations, however, CTG Resources's
management was unable to negotiate satisfactory terms, particularly relating to
regulatory approval standards, and the CTG Resources board of directors, at a
telephonic meeting held on May 31, 1999, instructed management to terminate
these discussions. The CTG Resources board of directors then authorized
management, with the assistance of PaineWebber, to explore alternative strategic
proposals to enhance the value of CTG Resources, including a possible sale. The
CTG Resources board of directors authorized PaineWebber to solicit preliminary
indications of interest from potential parties that might be interested in a
possible business combination involving CTG Resources.

    On June 1, 1999, CTG Resources issued a press release announcing that CTG
Resources had engaged the services of PaineWebber as its financial advisor to
assist CTG Resources in exploring strategic alternatives as a means for
enhancing shareholder value.

    In response to the CTG Resources board of directors' request,
representatives of PaineWebber contacted numerous potential financial and
strategic partners, including those companies with whom CTG Resources had
previously engaged in discussions. In response to these contacts, only a limited
number of entities was willing to enter into a confidentiality agreement with
CTG Resources. PaineWebber then distributed to those entities a memorandum
generally describing CTG Resources's operations and containing additional
nonpublic information about CTG Resources. Representatives of PaineWebber also
provided a letter to those entities advising them that CTG Resources reserved
its rights to terminate or revise the process and requesting that all
preliminary indications of interest be submitted in writing by July 8, 1999 to
enable CTG Resources to select a group of qualified parties to conduct more
detailed due diligence.

    Following the issuance of the June 1 press release, J.R. Crespo, the
chairman, president and chief executive officer of Connecticut Energy, contacted
Mr. Marquardt and inquired whether CTG Resources would be interested in
exploring a possible transaction with Energy East, which had recently

                                       31
<PAGE>
announced a merger transaction with Connecticut Energy. Mr. Crespo indicated
that Energy East would require that any discussions between the two companies be
conducted on an accelerated basis. Mr. Marquardt indicated that CTG Resources
would be interested in discussions with Energy East, but would be willing to
proceed with discussions on an accelerated basis only if Energy East were
willing to discuss a transaction with terms and conditions generally comparable
to recent transactions involving local gas distribution companies, including the
pending acquisition of Connecticut Energy by Energy East.

    On June 11, 1999, Mr. Marquardt met with Mr. Crespo. During that meeting,
Messrs. Crespo and Marquardt discussed Connecticut Energy's pending transaction
with Energy East, the opportunities present in the gas utility market and Energy
East's vision of establishing a premier distribution, transmission and energy
services company in the northeastern United States. Messrs. Crespo and Marquardt
began to discuss the potential benefits of a possible business combination
between CTG Resources and Energy East. Members of the CTG Resources board of
directors were advised of these discussions over the weekend of June 12 and 13,
1999.

    On June 14, 1999, Mr. Marquardt contacted Mr. Crespo about arranging a
meeting with Mr. Crespo and Wesley W. von Schack, the chairman, president and
chief executive officer of Energy East, to continue discussions regarding a
business combination between the two companies.

    On June 16, 1999, Messrs. Crespo, Marquardt and von Schack met to discuss
trends in the utility industry, strategic issues in the context of a possible
business combination between the two companies and the procedures for the
commencement of due diligence investigations and the exchange of financial
information. Following these discussions, Mr. Marquardt indicated that he would
be willing to discuss with CTG Resources's board of directors a transaction in
which CTG Resources would become a direct subsidiary of Energy East on terms and
conditions that would generally be comparable to the terms and conditions of the
Connecticut Energy-Energy East transaction and that would provide CTG Resources
shareholders with a premium to book value for their shares comparable to that
received by shareholders of other local gas distribution companies in recent
transactions. Mr. von Schack indicated that he would be willing to discuss such
a transaction with Energy East's board of directors. Following this meeting, CTG
Resources's advisors had several discussions with Energy East's advisors about
the general terms and conditions on which CTG Resources would be willing to
enter into a business combination with Energy East.

    On June 18, 1999, CTG Resources and Energy East entered into a
confidentiality agreement pursuant to which they agreed to exchange non-public
information. During the weekend of June 19 and 20, 1999, representatives of
PaineWebber and Morgan Stanley (representing Energy East) exchanged detailed
financial information and discussed due diligence matters.

    On June 21, 22 and 23, 1999, members of senior management of CTG Resources
and Energy East and their financial and legal advisors held discussions
pertaining to the terms of a proposed business combination and general business
issues, and conducted due diligence investigations. The discussions on the terms
of a transaction related to the amount and composition of the merger
consideration, a proposed corporate structure and management structure and
roles, including the terms of Mr. Marquardt's employment following the merger.
Working groups composed of employees of both companies and their independent
accountants and financial advisors were formed to examine various issues,
including financial benefits and risks of the proposed transaction, regulatory
issues relating to the proposed transaction, opportunities and disadvantages to
employees that a transaction would present, the impact on CTG Resources's
communities of a transaction, the impact of change in control and severance
arrangements and identification of possible operational benefits and
difficulties of combining the two companies.

    On June 24 and 25, 1999, phone conferences were held on the terms of the
merger agreement between the legal advisors for each company. Negotiations
involving management and their outside

                                       32
<PAGE>
financial advisors continued on the terms and pricing of the transaction,
including the exchange ratio. Follow-up due diligence issues were resolved by
legal representatives.

    During that week and over the weekend of June 26 and 27, 1999, Mr. Marquardt
contacted each member of the CTG Resources board of directors and informed them
of the status of the negotiations with Energy East.

    On June 28, 1999, the CTG Resources board of directors met in a telephonic
meeting. At this meeting, the CTG Resources board of directors was updated by
senior management regarding the proposed business combination, including
potential strategic benefits and potential risks of the transaction, the status
of negotiations on, and key terms and conditions of, the proposed merger
agreement and related employment agreement for Mr. Marquardt, the regulatory
plan for the transaction and the status of CTG Resources's due diligence review
of Energy East. James P. Bolduc, CTG Resources's executive vice president and
chief financial officer, provided the directors with an in-depth review of CTG
Resources's due diligence investigation of Energy East. Representatives of
PaineWebber presented a general overview of the financial aspects of the
transaction, including a presentation on the methodology by which PaineWebber
would conduct its fairness review. Legal counsel provided advice regarding the
CTG Resources board of directors' legal responsibilities and fiduciary duties in
considering the proposed transaction and the status of negotiations regarding
the merger agreement. Legal counsel also outlined the proposed forms of merger
agreement and employment agreement and discussed the draft disclosure schedules
to the merger agreement, which had been previously sent to the directors. At
that meeting, CTG Resources's senior management also discussed its strategic
conclusions with the board of directors. Energy East was identified as the most
likely candidate to enhance value for the CTG Resources shareholders. Following
lengthy discussions, the CTG Resources board of directors authorized senior
management to complete negotiations with Energy East and provided direction with
respect to various merger agreement issues.

    On June 29, 1999, at a special meeting, the CTG Resources board of directors
met and received updates from its senior management and financial and legal
advisors as to the terms of the merger agreement and related employment
agreement. Legal advisors and PaineWebber described various minor changes to the
merger agreement since the draft reviewed by the CTG Resources board of
directors at the previous day's meeting. Final drafts of the merger agreement,
employment agreement and disclosure schedules to the merger agreement were
reviewed at the meeting. After these presentations and a question and answer
period, PaineWebber delivered its fairness opinion to the CTG Resources board of
directors to the effect that, as of that date, the consideration to be received
in connection with the merger was fair from a financial point of view to the
holders of CTG Resources common stock. After considering and discussing the
various presentations at that meeting and at prior meetings, as well as the
recommendation of CTG Resources's senior management, the CTG Resources board of
directors approved, by a unanimous vote, the merger agreement and authorized the
execution of the merger agreement. Mr. Marquardt did not vote on those matters
relating to his employment agreement, which were unanimously approved by the
other directors.

    Following the meetings of their respective boards of directors, CTG
Resources and Energy East executed the merger agreement on the evening of June
29, 1999 and publicly announced the merger the next morning.

CTG RESOURCES REASONS FOR THE MERGER

    The CTG Resources board of directors believes that the merger will join two
companies with complementary operations as well as a common vision of the future
of the retail and wholesale energy markets in the northeastern region of the
United States. The CTG Resources board of directors believes that, as a result
of the increasing competitive pressures faced by natural gas utility companies
in the northeastern United States, CTG Resources would be better prepared to
succeed in such a

                                       33
<PAGE>
market if it were to combine its operations with those of a diversified energy
services provider like Energy East. The CTG Resources board of directors expects
the merger to facilitate the realization of these goals and to provide
substantial strategic and financial benefits to the CTG Resources shareholders,
as well as to employees and customers of CTG Resources and its subsidiaries. The
CTG Resources board of directors believes that these benefits include:

    - COMPETITIVE AND STRATEGIC POSITION. The merger is intended to establish a
      combined company that is able to compete more effectively in unregulated
      markets and serve customers more effectively in regulated markets. The
      combination of the companies' complementary expertise and infrastructure,
      including Energy East's diversified electric and natural gas businesses
      throughout the northeastern United States, should provide the combined
      company with the size and scope to be an effective competitor in the
      emerging and increasingly competitive markets for transporting and
      distributing energy and energy services. Moreover, Energy East's pending
      transactions with Connecticut Energy and CMP Group provide an enhanced
      opportunity for increased benefits to the shareholders of the combined
      entity.

    - NEW PRODUCTS AND SERVICES. The merger, as well as the pending CMP Group
      and Connecticut Energy mergers, will enable Energy East to provide
      customers with multiple energy products and services at lower costs than
      CTG Resources could provide alone.

    - INCREASED FINANCIAL STRENGTH AND CUSTOMER BASE. The combined company will
      be financially stronger and will have a broader customer base than CTG
      Resources as an independent entity. Based on the 1998 results for CTG
      Resources and Energy East, the total annual revenues for the combined
      company will be approximately $2.2 billion. In addition, the combined
      company will serve approximately 826,000 electric customers in New York
      and approximately 387,000 natural gas customers in New York and
      Connecticut. Moreover, after the Connecticut Energy and CMP Group mergers,
      the combined company will have $3.4 billion in total annual revenues
      (based on 1998 results) and will serve approximately 1,359,000 electric
      customers and 545,000 natural gas customers.

    - ENERGY EAST'S GROWTH STRATEGY. This combination will enhance the
      likelihood that Energy East can realize its goal of selectively growing
      its energy distribution business in the northeastern United States.

    - COMMUNITY DEVELOPMENT. The combined company will continue to play a
      leading role in the economic development of the communities served by CTG
      Resources. These communities also will benefit from increased competition
      for regulated and deregulated natural gas and electricity and energy
      related products and services.

RECOMMENDATION OF THE CTG RESOURCES BOARD OF DIRECTORS

    THE CTG RESOURCES BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT CTG
RESOURCES SHAREHOLDERS VOTE FOR THE APPROVAL OF THE MERGER AGREEMENT.

    At a special meeting held on June 29, 1999, after determining that the
merger is fair to and in the best interests of CTG Resources and its
shareholders, the CTG Resources board of directors unanimously approved and
adopted the merger agreement. In approving the merger agreement and in reaching
its recommendation, the CTG Resources board of directors consulted with and
relied upon information and reports prepared or presented by CTG Resources's
management and CTG Resources's legal and financial advisors. The following are
the material factors that the CTG Resources board of directors considered, some
of which contain both positive and negative elements:

    - the CTG Resources board of directors' understanding of the present and
      anticipated environment in the utility industry, and how possible
      consolidation within the utility industry could affect CTG Resources's
      competitive position in the industry;

                                       34
<PAGE>
    - the CTG Resources board of directors' consideration of the financial
      condition, results of operations, prospects and businesses of CTG
      Resources and Energy East, including the revenues of the companies, their
      complementary businesses, the recent stock price performance of CTG
      Resources shares and Energy East shares and the percentage of the combined
      company to be owned by CTG Resources shareholders following the merger;

    - current industry, economic and market conditions;

    - other strategic options potentially available to CTG Resources;

    - the fact that the corporate headquarters of the surviving company (which
      will be a subsidiary of Energy East) will remain in Hartford, Connecticut;

    - the fact that the nonregulated operations of Energy East will be
      headquartered in Connecticut;

    - the beneficial effect of increased competition on Connecticut Natural
      Gas's customers;

    - the beneficial effects of the merger on the municipalities served and
      other societal concerns;

    - the financial and business prospects for the combined company;

    - the CTG Resources per share consideration of $41.00, which represents an
      approximate 15.1% premium to the closing price of a CTG Resources share on
      June 29, 1999, the last full trading day prior to the public announcement
      of the merger, and an approximate 60.4% premium to the closing price of a
      CTG Resources share on May 28, 1999, the last trading day prior to CTG
      Resources's public announcement that it had retained PaineWebber to
      explore strategic alternatives to enhance shareholder value;

    - the fact that the merger agreement provides CTG Resources shareholders
      with an opportunity to receive cash for their CTG Resources shares (even
      though the amount of cash is subject to proration and an adjustment driven
      by tax considerations);

    - the anticipated level of the Energy East dividend following completion of
      the merger and its growth potential;

    - the corporate governance aspects of the merger, including the fact that
      (1) one new director, who is a non-employee director of CTG Resources and
      who will be designated by CTG Resources and reasonably acceptable to
      Energy East, will be appointed to the Energy East board of directors, (2)
      Mr. Marquardt will be the president and chief executive officer of the
      board of directors of the surviving company (which will be a subsidiary of
      Energy East) and will hold officer positions in other Energy East
      subsidiaries and (3) the surviving company will create an advisory board,
      whose members will be the same individuals who were directors of CTG
      Resources immediately before the completion of the merger;

    - the opinion of counsel expected to be delivered, as a condition to the
      merger, at the closing of the merger to the effect that the merger will be
      treated as a reorganization within the meaning of Section 368(a) of the
      Internal Revenue Code. If the merger is a reorganization, then CTG
      Resources shareholders who exchange their CTG Resources shares solely for
      Energy East shares, as well as CTG Resources, Energy East and Oak Merger
      Co., will recognize no gain or loss for U.S. federal income tax purposes
      as a result of the consummation of the merger. It is also expected that
      those CTG Resources shareholders who exchange their CTG Resources shares
      for cash will generally be eligible for capital gains treatment;

    - the interests of certain persons in the merger, including Mr. Marquardt;

    - the opinion of PaineWebber that, as of June 29, 1999, and subject to the
      considerations described therein, the consideration to be received by the
      CTG Resources shareholders was fair from a financial point of view to
      those shareholders;

                                       35
<PAGE>
    - the other advice from CTG Resources management and the CTG Resources board
      of directors' financial and legal advisors over an extended period, and
      the discussions of the CTG Resources board of directors concerning the
      proposed merger agreement;

    - the ability to obtain regulatory approvals for the merger in the current
      environment; and

    - the fact that Energy East was actively acquiring other utilities
      properties in Connecticut and Maine.

    The CTG Resources board of directors also considered (1) the risk that the
benefits sought in the merger would not be obtained, (2) the risk that the
merger would not be completed, (3) the effect of the public announcement of the
merger on CTG Resources's sales, customer, supplier and creditor relationships,
operating results and ability to retain employees and the trading price of CTG
Resources shares, (4) the substantial management time and effort that will be
required to complete the merger and integrate the operations of the two
companies, (5) the impact of the merger on CTG Resources employees, (6) the
possibility that various provisions of the merger agreement might have the
effect of discouraging other persons potentially interested in a combination
with CTG Resources from pursuing such an opportunity, (7) the risk that the
value of Energy East shares will decline and (8) other matters described under
"Risk Factors" and "Cautionary Statement Regarding Forward-Looking Statements."

    This discussion of the information and factors considered by the CTG
Resources board of directors is not intended to be exhaustive. In view of the
wide variety of factors considered, the CTG Resources board of directors did not
assign relative weights to the factors discussed above or determine that any
factor was of particular importance. Rather, the CTG Resources board of
directors based its recommendation upon the totality of the information
presented.

OPINION OF THE FINANCIAL ADVISOR TO THE CTG RESOURCES BOARD

    THE FULL TEXT OF THE PAINEWEBBER OPINION, DATED JUNE 29, 1999, WHICH SETS
FORTH THE ASSUMPTIONS MADE, PROCEDURES FOLLOWED, MATTERS CONSIDERED AND
LIMITATIONS ON THE REVIEW UNDERTAKEN, IS ATTACHED AS APPENDIX B TO THIS PROXY
STATEMENT/PROSPECTUS. CTG RESOURCES SHAREHOLDERS ARE URGED TO READ THIS OPINION
CAREFULLY AND IN ITS ENTIRETY. THE SUMMARY OF THE PAINEWEBBER OPINION SET FORTH
IN THIS PROXY STATEMENT/PROSPECTUS IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO
THE FULL TEXT OF THIS OPINION. THE PAINEWEBBER OPINION IS NOT A RECOMMENDATION
TO ANY SHAREHOLDER AS TO HOW TO VOTE ON THE MERGER.

    CTG Resources retained PaineWebber as its exclusive financial advisor in
connection with the merger. In connection with such engagement, CTG Resources
requested PaineWebber to render an opinion as to whether or not the merger
consideration is fair, from a financial point of view, to CTG Resources
shareholders.

    In connection with the CTG Resources board of directors' consideration of
the merger, PaineWebber delivered the PaineWebber opinion, to the effect that,
as of June 29, 1999, and based on its review and assumptions and subject to the
limitations summarized below, the merger consideration is fair, from a financial
point of view, to CTG Resources shareholders. The PaineWebber opinion was
prepared at the request and for the information of the CTG Resources board of
directors and does not constitute a recommendation to any CTG Resources
shareholder as to how to vote on the merger. The PaineWebber opinion does not
address the relative merits of the merger or any other transactions or business
strategies that the CTG Resources board of directors may have discussed as
alternatives to the merger or the decision of the CTG Resources board of
directors to proceed with the merger. CTG Resources did not place any
limitations upon PaineWebber with respect to the procedures followed or factors
considered in rendering the PaineWebber opinion.

                                       36
<PAGE>
    In arriving at its opinion, PaineWebber, among other things:

    - reviewed among other public information, CTG Resources's annual reports,
      Forms 10-K and related financial information for the five fiscal years
      ended September 30, 1998 and CTG Resources's Form 10-Q and the related
      unaudited financial information for the six months ended March 31, 1999;

    - reviewed among other public information, Energy East's annual reports,
      Forms 10-K and related financial information for the five fiscal years
      ended December 31, 1998 and Energy East's Form 10-Q and the related
      unaudited financial information for the three months ended March 31, 1999;

    - reviewed information, including financial forecasts, relating to the
      business, earnings, cash flow, assets and prospects of CTG Resources and
      Energy East, furnished to PaineWebber by CTG Resources and Energy East;

    - conducted discussions with members of senior management of CTG Resources
      and Energy East concerning their businesses and prospects;

    - compared the historical market prices and trading activity for CTG
      Resources shares and Energy East shares with those of certain publicly
      traded companies that PaineWebber deemed to be relevant;

    - compared the financial position and results of operations of CTG Resources
      and Energy East with those of certain publicly traded companies that
      PaineWebber deemed to be relevant;

    - compared the proposed financial terms of the merger with the financial
      terms of certain other mergers and acquisitions that PaineWebber deemed to
      be relevant;

    - considered the potential pro forma effects of the merger on Energy East;

    - reviewed a draft of the merger agreement in the form presented to CTG
      Resources's board of directors; and

    - reviewed other financial studies and analyses, performed other
      investigations and took into account other matters as PaineWebber deemed
      necessary, including PaineWebber's assessment of regulatory, general
      economic, market and monetary conditions.

    In preparing its opinion, PaineWebber relied on the accuracy and
completeness of all information that was publicly available, supplied or
otherwise communicated to PaineWebber by or on behalf of CTG Resources and
Energy East. PaineWebber has not assumed any responsibility to verify
independently this information. With respect to the financial forecasts examined
by PaineWebber, CTG Resources and Energy East have represented to it, and
PaineWebber has assumed, with CTG Resources's consent, that they were reasonably
prepared and reflect the best currently available estimates and good faith
judgments of the managements of CTG Resources and Energy East as to the future
performance of CTG Resources and Energy East. PaineWebber has also relied upon
assurances of the managements of CTG Resources and Energy East that they were
unaware of any facts that would make the information or financial forecasts
provided to PaineWebber incomplete or misleading. PaineWebber did not make an
independent evaluation or appraisal of the assets or liabilities (contingent or
otherwise) of CTG Resources or Energy East, nor was PaineWebber furnished with
any such evaluations or appraisals. PaineWebber has also assumed, based on CTG
Resources's and Energy East's representations and with CTG Resources's consent,
that any material liabilities (contingent or otherwise, known or unknown) of CTG
Resources or Energy East are as set forth in the consolidated financial
statements of CTG Resources and Energy East. The PaineWebber opinion is based
upon regulatory, general economic, market and monetary conditions existing on
the date of the opinion. PaineWebber expressed no opinion as to the price at
which CTG Resources shares or Energy East

                                       37
<PAGE>
shares may trade at any time after the date of the PaineWebber opinion. It
should be understood that, although subsequent developments may affect the
PaineWebber opinion, PaineWebber does not have any obligation to update, revise
or reaffirm its opinion.

    The preparation of a fairness opinion involves various determinations as to
the most appropriate and relevant quantitative methods of financial analyses and
the application of those methods to the particular circumstances. Therefore,
such an opinion is not readily susceptible to partial analysis or summary
description. Accordingly, PaineWebber believes that its analysis must be
considered as a whole and that considering any portion of its analysis and of
the factors considered, without considering all analyses and factors, could
create a misleading or incomplete view of the process underlying the PaineWebber
opinion. In its analyses, PaineWebber made numerous assumptions with respect to
industry performance, general business and economic conditions and other
matters, many of which are beyond the control of CTG Resources and Energy East.
Any estimates contained in these analyses are not necessarily indicative of
actual values or predictive of future results or values, which may be
significantly more or less favorable than as set forth in these analyses. In
addition, analyses relating to the value of businesses do not purport to be
appraisals or to reflect the prices at which businesses may be sold.
Accordingly, these analyses and estimates are inherently subject to substantial
uncertainty, and neither CTG Resources nor PaineWebber assume responsibility for
the accuracy of these analyses and estimates.

    The following paragraphs summarize the significant analyses performed by
PaineWebber in arriving at its opinion.

    STOCK TRADING HISTORY.  PaineWebber reviewed the history of the trading
prices for CTG Resources shares and Energy East shares, both separately and in
relation to a market index and to comparable companies. The comparable companies
were selected based on several criteria, including relative size, profitability,
total revenue, growth characteristics, business position and credit rating. The
market index used was the Standard & Poor's 40 Utilities Index. The CTG
Resources comparable companies consisted of:

EnergyNorth, Inc.
Indiana Energy, Inc.
Laclede Gas Company
New Jersey Resources Corporation
Northwest Natural Gas Company
Providence Energy Corporation
SEMCO Energy, Inc.
South Jersey Industries, Inc.

    The Energy East comparable companies consisted of:

Alliant Energy Corporation
Ameren Corporation
Constellation Energy Group, Inc.
DPL Inc.
LG&E Energy Corp.
Puget Sound Energy, Inc.
Wisconsin Energy Corporation

    SELECTED COMPARABLE PUBLIC COMPANY ANALYSIS.  Using publicly available
information, PaineWebber compared selected historical and projected financial,
operating and stock market performance data of CTG Resources and Energy East to
the corresponding data of the above-mentioned comparable companies.

    With respect to CTG Resources and its comparable companies, PaineWebber
calculated multiples of total enterprise value (market value, as hereinafter
defined, plus preferred stock and debt less cash and cash equivalents) to (1)
latest twelve months ("LTM") earnings before interest, taxes and depreciation
and amortization ("EBITDA") and (2) LTM earnings before interest and taxes
("EBIT"). PaineWebber also calculated multiples of market value (share price
multiplied by shares outstanding including in-the-money options and warrants) to
(1) LTM net income, (2) projected fiscal year 1999 earnings per share ("EPS"),
(3) projected fiscal year 2000 EPS, (4) LTM cash flow from operations (net
income plus depreciation and amortization) and (5) book value of equity. The
comparable companies' projected fiscal year 1999 and 2000 EPS results were based
on publicly available estimates from First Call Research. The CTG Resources
comparable companies analysis resulted in the following ranges of multiples as
of June 25, 1999:

    SELECTED COMPARABLE MERGERS AND ACQUISITIONS ANALYSIS.  PaineWebber reviewed
publicly available financial information for selected completed and pending
mergers and acquisitions involving companies in the gas distribution business.
The selected mergers and acquisitions PaineWebber analyzed included
(acquiror/target):

Wisconsin Energy Corporation / WICOR, Inc.
Northeast Utilities / Yankee Energy System, Inc.
Southern Union Company / Pennsylvania Enterprises, Inc.
ONEOK, Inc. / Southwest Gas Corporation

    DISCOUNTED CASH FLOW ANALYSIS.  PaineWebber analyzed CTG Resources based on
an unleveraged discounted cash flow analysis of the projected financial
performance of CTG Resources. This projected financial performance was based
upon a five-year forecast for CTG Resources provided by CTG Resources
management. The discounted cash flow analysis determined the discounted present
value of the unleveraged after-tax cash flows generated over the five-year
period and then added a terminal value based upon a range of EBITDA multiples of
6.5x to 8.5x and EBIT multiples from 10.0x to 12.0x. The unleveraged after-tax
cash flows and terminal value were discounted using a range of discount rates
that represented an estimate of the weighted average cost of capital of CTG
Resources.

    PREMIUMS PAID ANALYSIS.  PaineWebber analyzed purchase price per share
premiums paid in 105 publicly-disclosed domestic transactions, in non-financial
industries, with transaction values between $100 million and $700 million,

    PRO FORMA MERGER ANALYSIS.  PaineWebber performed an analysis of the
potential pro forma effect of the merger on Energy East's (1) EPS and (2) cash
flow from operations less dividends per share for the fiscal years 2000 through
2004. PaineWebber combined the projected operating results of CTG Resources
(provided by CTG Resources management) with the corresponding projected
operating results of Energy East (provided by Energy East management) to arrive
at the combined company projected (1) net income and (2) cash flow from
operations less dividends. PaineWebber divided the combined company projected
(1) net income and (2) cash flow from operations less dividends by the pro forma
shares outstanding to arrive at the combined company projected (1) EPS and (2)
cash flow from operations less dividends per share. PaineWebber then compared
the combined company projected (1) EPS and (2) cash flow from operations less
dividends per share to Energy East's projected stand-alone results (provided by
Energy East management) to determine the projected pro forma impact on Energy
East. This analysis suggested that, without assuming any cost savings due to the
merger, the merger would result in dilution to Energy East's EPS and accretion
to Energy East's cash flow from operations less dividends per share.

    CTG Resources selected PaineWebber to be its financial advisor in connection
with the merger because PaineWebber is a prominent investment banking and
financial advisory firm with experience in the valuation of businesses and their
securities in connection with mergers and acquisitions, negotiated
underwritings, secondary distributions of securities, private placements and
valuations for corporate purposes.

    Pursuant to an engagement letter between CTG Resources and PaineWebber dated
June 25, 1998, PaineWebber has earned a retention fee of $200,000 and a fee of
approximately $1,742,000 for the rendering of the PaineWebber opinion and the
public announcement of the merger. In addition, PaineWebber will receive a fee
of approximately $1,642,000, payable upon completion of the merger, and will be
reimbursed for certain of its related expenses. PaineWebber will not be entitled
to any additional fees or compensation in the event the merger is not approved
or otherwise completed. CTG Resources also agreed, under separate agreement, to
indemnify PaineWebber, its affiliates and each of its directors, officers,
agents and employees and each person, if any, controlling PaineWebber or any of
its affiliates against certain liabilities, including liabilities under federal
securities laws.

    In the past, PaineWebber and its affiliates have provided investment banking
and other financial services to CTG Resources and have received fees for the
rendering of these services. PaineWebber may provide financial advisory services
to, and may act as underwriter or placement agent for, the combined company in
the future. In the ordinary course of PaineWebber's business, PaineWebber may
actively trade the securities of CTG Resources and Energy East for its own
account and for the accounts of its customers and, accordingly, may at any time
hold long or short positions in such securities.

EFFECTIVE TIME OF THE MERGER

    The merger will become effective when the parties to the merger agreement
file a certificate of merger with the Secretary of the State of Connecticut in
accordance with the Connecticut Business Corporation Act, or at a later time
that Energy East and CTG Resources may specify in the certificate of merger.

    The merger will not become effective before the date of the special meeting.
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 all required regulatory approvals.

                                       42
<PAGE>
CERTIFICATE OF INCORPORATION AND BY-LAWS

    The certificate of incorporation of Oak Merger Co., in effect immediately
prior to the effective time of the merger, will become the certificate of
incorporation of the surviving company until it is amended, except that the name
of the surviving company will be "CTG Resources, Inc." The by-laws of Oak Merger
Co. in effect immediately prior to the effective time will be the by-laws of the
surviving company, until they are amended.

DIRECTORS AND OFFICERS

    DIRECTORS.  After the merger becomes effective, the board of directors of
the surviving company will consist of the current directors of Oak Merger Co.
and Mr. Marquardt. These directors will hold office until their successors are
duly elected or appointed and qualified. In addition, pursuant to the merger
agreement, Energy East will add a member to its board of directors. This seat
will be filled by one of the current directors of CTG Resources, as designated
by CTG Resources and reasonably acceptable to Energy East. The additional
director will not be an employee of the surviving company.

    OFFICERS.  Once the merger becomes effective, Mr. Marquardt will be the
president and chief executive officer of the surviving company (which will be a
subsidiary of Energy East). He will also hold officer positions in other Energy
East subsidiaries, as specified in an employment agreement that he and Energy
East have signed. The other officers of the surviving company will be the same
individuals who hold the officer positions of Oak Merger Co. immediately prior
to the time the merger becomes effective. All officers will hold their positions
until their successors are duly elected or appointed and qualified.

ACCOUNTING TREATMENT

    The merger will be accounted for as an acquisition of CTG Resources by
Energy East under the purchase method of accounting in accordance with generally
accepted accounting principles. A portion of the purchase price will be
allocated to nonutility assets and liabilities of CTG Resources based on their
estimated fair market value at the date of acquisition. As a regulated utility,
the assets and liabilities of Connecticut Natural Gas will not be revalued. The
difference between the purchase price, representing fair value, and the recorded
amounts will be shown as goodwill on the balance sheet.

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 currently believe that the necessary approvals can be obtained in the
middle of the year 2000.

    CONNECTICUT DEPARTMENT OF PUBLIC UTILITY CONTROL.  The Connecticut
Department of Public Utility Control has jurisdiction over Connecticut Natural
Gas, CTG Resources's principal operating subsidiary, as a Connecticut public
service company. Connecticut Natural Gas is a public service company under
Connecticut law because it is a gas company distributing gas for heat or power
within Connecticut. An application has been filed with the Department. The
application requests approval for Energy East to control directly CTG Resources
and to control indirectly Connecticut Natural Gas pursuant to Connecticut law.
The Department will consider the suitability and financial responsibility of
Energy East as well as the ability of Connecticut Natural Gas to provide safe,
adequate and reliable service to the public through its plant, equipment, and
manner of operation were the application to be approved.

                                       43
<PAGE>
    Within 30 business days after the filing of the application, the Department
must give notice of and begin a public hearing, which will be held at the
offices of the Department. The Department must issue a decision on the
application within 120 days after the filing date, unless the applicants agree
to an extension of time. The Department may request and receive an extension.

    Energy East and CTG Resources believe that their application to the
Department will fully comply with the requirements of Connecticut law and will
include in their application testimony intended to demonstrate compliance with
Connecticut law. Nonetheless, opposition to the application is possible. The
Connecticut Office of Consumer Counsel has the statutory authority to appear in
and participate in the proceeding, and is expected to be named as a party in the
Department hearings. The parties to the proceedings will be entitled to conduct
discovery, which will likely consist of interrogatories addressed to the
applicants by Department staff, by the Office of Consumer Counsel, and possibly
by other intervening parties, including the Connecticut Attorney General. Energy
East and CTG Resources can give no assurance that the necessary Department
approvals will be obtained in a timely manner or at all. Moreover, it is
possible that the Department approvals will include conditions that, if
accepted, would result in a material adverse effect on Energy East or CTG
Resources. If so, the parties would not be obligated to complete the merger.

    In addition, Energy East must obtain the Department's approval of Energy
East's merger with Connecticut Energy. The Department could delay approval of
either or both merger applications or impose burdensome conditions to the
completion of the mergers.

    THE PUBLIC UTILITY HOLDING COMPANY ACT.  In addition to its merger agreement
with CTG Resources, Energy East has entered into merger agreements with CMP
Group, an exempt public utility holding company located in Maine, and
Connecticut Energy, an exempt public utility holding company located in
Connecticut. Energy East expects that if it completes the pending merger with
CMP Group, it will no longer be eligible for an exemption under the Public
Utility Holding Company Act and has agreed that it will register with the SEC as
a public utility holding company under the Public Utility Holding Company Act.

    The Public Utility Holding Company Act imposes restrictions on registered
holding companies. Among these restrictions are requirements that the SEC
approve certain securities issuances, sales and acquisitions of utility assets
or securities of utility companies, and acquisitions of interests in any other
business. A registered holding company is permitted to own one integrated public
utility system, as well as additional utility systems, provided the SEC makes
the necessary findings. The Public Utility Holding Company Act also limits the
ability of registered holding companies to engage in nonutility ventures and
regulates transactions between various affiliates within a holding company
system, including the provision of services by holding company affiliates to the
system's utilities.

    In connection with the merger with CTG Resources, as well as the other
mergers described above, Energy East must obtain SEC approval under Section
9(a)(2) of the Public Utility Holding Company Act. Section 9(a)(2) of the Public
Utility Holding Company Act requires an entity owning, directly or indirectly, 5
percent or more of the outstanding voting securities of a public utility company
(as defined in the Public Utility Holding Company Act) to obtain the approval of
the SEC before acquiring a direct or indirect interest in 5 percent or more of
the voting securities of any additional public utility company. Energy East
currently holds in excess of 5 percent of the voting securities of two public
utility companies -- NYSEG and CMP Natural Gas. In the merger with CTG
Resources, Energy East will be indirectly acquiring more than 5 percent of the
voting securities of Connecticut Natural Gas, a public utility company within
the meaning of the Public Utility Holding Company Act. Energy East will also
indirectly acquire more than 5 percent of the voting securities of the public
utility subsidiaries of Connecticut Energy and CMP Group.

    Under the applicable standards of the Public Utility Holding Company Act,
the SEC may not approve a merger if it finds that (1) the merger would tend
towards detrimental interlocking relations or a detrimental concentration of
control, (2) the consideration to be paid in connection with the merger is not
reasonable, (3) the merger would unduly complicate the capital structure of the
acquiror's holding company system or would be detrimental to the proper
functioning of its holding company system or (4) the merger would violate
applicable state law. To approve the merger, the SEC must also find that the
merger would serve the public interest by tending toward the development of an
integrated public utility system. It is anticipated that Energy East's mergers
with CTG Resources, Connecticut Energy and CMP Group will comply with these
standards.

    Section 10(c)(1) of the Public Utility Holding Company Act prevents the SEC
from approving an acquisition that "would be detrimental to the carrying out of
the provisions of section 11." Section 11(b)(1) of the Public Utility Holding
Company Act generally confines the utility properties of a registered holding
company to a "single integrated public-utility system," either gas or electric.
An exception to the requirement of a "single system" is provided in section
11(b)(1)(A), (B) and (C), the so-called ABC clauses. Under the exception, a
registered holding company may control one or more additional integrated public
utility systems if (A) each of these additional systems cannot be operated as an
independent system without the loss of substantial economies of scale; (B) all
of these additional systems are located in one state, adjoining states, or a
contiguous foreign country; and (C) the continued combination of these systems
under the control of such holding company is not so large as to impair the
advantages of localized management, efficient operation, or the effectiveness of
regulation.

    Energy East believes that its gas system, Connecticut Energy's gas system,
and Connecticut Natural Gas will constitute a "single integrated public-utility
system" within the meaning of the Public Utility Holding Company Act and that
this system will be retainable under that Act. There can be no assurance,
however, that the SEC will approve the merger under the Public Utility Holding
Company Act or that the gas system will be found retainable under that Act, or
if approval is obtained, when it will be obtained or whether the terms of the
approval will ultimately be acceptable. In addition, Energy East anticipates
that the SEC will find that the merger with CMP Group complies with the
integration standards under the Public Utility Holding Company Act, although
there can be no assurance of this.

    The SEC could also require, as a condition to its approval of the merger
under the Public Utility Holding Company Act, that Energy East or CTG Resources
divest some of its investments that are unrelated to the combined company's
post-merger utility operations. In several cases, the SEC has allowed the
retention of nonutility investments or deferred the question of divesture for a
substantial period of time. In cases in which a divestiture has been ordered,
the SEC has usually allowed enough time to complete the divestiture to avoid a
"fire sale" of the divested assets. Based on existing SEC policy and precedent,
it appears likely that the SEC will permit the retention by the combined company
of nonutility investments or, alternatively, will defer the question of
divestiture for a substantial period of time.

    ANTITRUST.  Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976
and the rules promulgated thereunder by the U.S. Federal Trade Commission, we
cannot complete the merger until we have given notifications 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. Energy East and CTG Resources will file notification and report
forms under the Hart-Scott Act with the Federal Trade Commission and the
Antitrust Division. Even after the waiting period expires or is terminated, the
Federal Trade Commission and the Antitrust Division retain the authority to
challenge the merger on antitrust grounds before or after the merger is
completed. In addition, each state in which CTG Resources or Energy East
operates may also seek to review the merger. It is possible that some of these
authorities or a private party may seek to challenge the merger.

    OBLIGATIONS TO OBTAIN REGULATORY APPROVALS.  Under the merger agreement,
both Energy East and CTG Resources have agreed to use all commercially
reasonable efforts to obtain all regulatory and governmental approvals necessary
or advisable to complete the merger.

    INJUNCTIONS.  Energy East's and CTG Resources's obligation to complete the
merger is subject to the condition that there be no law, regulation or
injunction in effect that would prohibit the completion of the merger.

LISTING OF THE ENERGY EAST SHARES ON THE NEW YORK STOCK EXCHANGE

    In the merger agreement, Energy East, Oak Merger Co. and CTG Resources have
agreed to use reasonable efforts to cause Energy East shares that are to be
issued pursuant to the merger agreement to be listed for trading on the New York
Stock Exchange. Approval for listing is a condition to the obligations of Energy
East, Oak Merger Co. and CTG Resources to complete the merger.

RESALE OF THE ENERGY EAST SHARES ISSUED IN THE MERGER; CTG RESOURCES AFFILIATES

    Energy East shares to be issued to CTG Resources shareholders in connection
with the merger will be freely transferable under the Securities Act of 1933,
except for Energy East shares issued to any person deemed to be an affiliate of
CTG Resources for purposes of Rule 145 promulgated under the Securities Act at
the time of the special meeting. These affiliates may not sell their Energy East
shares acquired in connection with the merger, except pursuant to an effective
registration statement under the Securities Act covering such Energy East
shares, or in compliance with Rule 145 promulgated under the Securities Act or
another applicable exemption from the registration requirements of the
Securities Act. Pursuant to the merger agreement, CTG Resources has delivered to
Energy East a letter identifying all persons who, at the time of the special
meeting, may be deemed to be its affiliates.

MERGER FINANCING

    In the merger, Energy East expects to pay CTG Resources shareholders
approximately $195 million in cash consideration. In addition, in its merger
with Connecticut Energy, Energy East expects to pay approximately $218 million
in cash consideration to Connecticut Energy shareholders; and in its merger with
CMP Group, Energy East expects to pay approximately $957 million in cash
consideration to CMP Group shareholders. Energy East anticipates funding the
cash consideration in the mergers with a combination of the proceeds from the
sales of its generation assets, the proceeds from the issuance of long-term debt
and internally generated funds.

INTERESTS OF CERTAIN PERSONS IN THE MERGER

    In considering the recommendation of the CTG Resources board of directors
with respect to the merger agreement, CTG Resources shareholders should be aware
that certain officers and directors of CTG Resources have interests in the
merger that are in addition to, or different from, the interests of CTG
Resources shareholders generally. The CTG Resources board of directors was aware
of these interests and considered them along with other matters in recommending
that CTG Resources shareholders vote to approve the merger agreement.

    ENERGY EAST BOARD OF DIRECTORS.  As provided in the merger agreement, Energy
East will add a director to the Energy East board of directors. This seat will
be filled by one of the current non-employee directors of CTG Resources, as
designated by CTG Resources and reasonably acceptable to Energy East. See "The
Merger Agreement -- Corporate Governance Matters."

    SURVIVING COMPANY OFFICER.  The merger agreement provides that, at the
effective time of the merger, Mr. Marquardt will become the president and chief
executive officer of the surviving company (which will be a subsidiary of Energy
East) and will hold officer positions in other subsidiaries of Energy East. See
"The Merger Agreement -- Corporate Governance Matters."

    ADVISORY BOARD.  Under the merger agreement, the present directors of CTG
Resources will continue as members of an advisory board of the surviving
company. The members of the advisory board will provide advice to the board of
directors of the surviving company with respect to various matters and receive
remuneration for their services equivalent to remuneration currently provided to
non-employee directors of CTG Resources. See "The Merger Agreement -- Additional
Agreements."

    EMPLOYMENT AGREEMENT.  Energy East and CTG Resources have signed an
employment agreement with Mr. Marquardt. The agreement will become effective at
the effective time of the merger, replacing Mr. Marquardt's existing
change-in-control employment agreement with CTG Resources described below under
"-- CTG Resources Change-in-Control Arrangements."

    The term of Mr. Marquardt's new employment agreement is three years,
beginning on the effective date of the merger, and is automatically extended
each year unless either Energy East, the surviving company or Mr. Marquardt
gives written notice that the agreement will not be extended. Under the terms of
his employment agreement, Mr. Marquardt will become the president and chief
executive officer of the surviving company (which will be a subsidiary of Energy
East) and a member of its board; the president, chief operating officer and a
member of the board of directors of XENERGY; a member of the board of directors
of Connecticut Energy; and will hold other officer positions in Energy East's
subsidiaries as the board of directors of Energy East may determine. Commencing
not later than the first anniversary of the effective time of the merger, Mr.
Marquardt will also serve as chief executive officer of XENERGY, at which time
he will cease to be chief operating officer thereof unless the Energy East board
of directors decides otherwise.

    Mr. Marquardt's base salary will not be less than $425,000 per year. Mr.
Marquardt will also be entitled to receive a special bonus of $400,000 within
five days of the effective time of the merger and two additional special bonuses
of $400,000 each if he is employed with Energy East or any Energy East
subsidiary on the first and second anniversaries of the merger. Mr. Marquardt
will participate in all incentive compensation, fringe benefit and employee
benefit plans on the same basis as other executives and key management
employees, including a company car, certain club dues and financial planning
services. Under his agreement, Mr. Marquardt will also be entitled to a special
retirement benefit (the "SPECIAL RETIREMENT BENEFIT") if he retires on or after
his sixtieth birthday or if his employment is terminated (i) within three years
after the effective time of the merger either by the surviving company for
reasons other than cause or disability or by Mr. Marquardt for good reason or
(ii) thereafter for any reason. The annual amount of the Special Retirement
Benefit payable to

                                       47
<PAGE>
Mr. Marquardt, expressed as a single life annuity, will equal the excess of 75%
of his highest annual rate of base salary over the amount of pension benefits to
which he will be entitled under all qualified and nonqualified defined benefit
plans of CTG Resources, Energy East and their affiliates and all of his prior
employers. The agreement also provides for a "gross-up" payment to Mr. Marquardt
if any payment, benefit or distribution to Mr. Marquardt is subject to excise
tax under Section 4999 of the Internal Revenue Code.

    Under the employment agreement, Energy East, the surviving company or Mr.
Marquardt may terminate Mr. Marquardt's employment at any time. If Energy East
or the surviving company terminates Mr. Marquardt's employment without cause
(other than his death or disability) or Mr. Marquardt terminates his employment
for good reason, he will receive:

    - payment of base salary through the effective date of termination and all
      compensation and benefits to which he is entitled under all compensation
      and benefit plans or policies;

    - a lump sum cash payment equal to three times the sum of (i) his base
      salary at the rate in effect at the time of termination, (ii) a short-term
      incentive compensation equivalent calculated on the basis of the value of
      the higher of (A) the short-term incentive compensation paid to him in
      respect of the most recently completed fiscal year and (B) the average of
      short-term incentive compensation amounts paid for the three most recently
      completed fiscal years, and (iii) the value of any outstanding long-term
      incentive compensation awards, determined based on the projected target
      value of the awards determined at the time of grant;

    - payment of his Special Retirement Benefit as and to the extent described
      above; and

    - continuation of all employee benefits under employee benefit plans in
      which he is participating for the remainder of the term of the employment
      agreement.

    We estimate that, if the merger occurred on July 1, 2000 and Mr. Marquardt's
employment were immediately terminated for one of the reasons noted above, he
would receive cash severance payments and gross-up payments pursuant to his new
employment agreement of approximately $4,693,600, not including the Special
Retirement Benefit.

    CTG RESOURCES CHANGE-IN-CONTROL ARRANGEMENTS.  Mr. Marquardt and eight other
executive officers have change-in-control employment agreements that provide
severance benefits if in certain circumstances they are either terminated after
a change in control or in anticipation thereof. The completion of the merger
would constitute a change in control as defined in these agreements. Mr.
Marquardt's new employment agreement will replace his current change-in-control
employment agreement at the effective time of the merger. Thus, Mr. Marquardt
will not be entitled to the change-in-control severance benefits provided for in
his current agreement if the merger is completed and his employment is
terminated thereafter. Under the other eight agreements, the following severance
benefits are provided if the executive's employment is terminated, within three
years following the merger, by the surviving company for any reason other than
death, disability or cause or by the executive for good reason:

    - payment of base salary through the effective date of termination, a
      prorated annual bonus based on the higher of the highest annual bonus for
      the last three fiscal years prior to the merger or the bonus payable for
      the most recently completed fiscal year prior to termination ("HIGHEST
      ANNUAL BONUS"), compensation previously deferred by the executive and
      earnings thereon and accrued vacation pay and all benefits and awards to
      which the executive is entitled under any benefit plan or policy;

                                       48
<PAGE>
    - a cash payment equal to two times (or three times for three executive
      officers), the sum of the executive's base salary in effect on the date of
      termination and his or her Highest Annual Bonus;

    - a cash payment equal to the actuarial equivalent of the additional
      retirement benefits that the executive would have received under the
      Connecticut Natural Gas qualified pension plan and officers' retirement
      plan had he or she remained employed under the terms of the employment
      agreement for up to an additional two (or three, where applicable) years;

    - continued welfare benefits (E.G., medical insurance, life insurance, etc.)
      for not less than two (or three, where applicable) years on terms no less
      favorable than the most favorable terms in effect during the 120-day
      period prior to the merger; and

    - payment of expenses for outplacement services in an amount not to exceed
      10% of base salary.

    Additionally, the agreements provide that, if any payment, benefit, or
distribution to the executive is subject to excise tax under Section 4999 of the
Internal Revenue Code, he or she will receive a tax "gross-up" payment.

    CTG Resources has also entered into an agreement with Jean McCarthy, vice
president of human resources services, that provides for a supplemental
retirement benefit payment if in certain circumstances she is terminated either
after a change in control or in anticipation thereof. The completion of the
merger would constitute a change in control as defined in her agreement. The
agreement provides that if Ms. McCarthy's employment is terminated within three
years following the merger by the surviving company for any reason other than
death, disability or cause or by Ms. McCarthy for good reason, she would be
entitled to a cash lump sum payment equal to the actuarial equivalent of the
additional retirement benefit she would have received under the Connecticut
Natural Gas qualified pension plan and officers' retirement plan if the benefits
were determined without regard to the provision in the officers' retirement plan
providing for a pro rata reduction if the executive has less than 15 years of
service at termination. However, the agreement further provides that the right
to such payment will be reduced to the extent such payment when added to other
payments or distributions to be received by Ms. McCarthy would give rise to an
excise tax under Section 4999 of the Internal Revenue Code but such reduction
shall only be made if the reduction would result in an increase in the aggregate
benefits and payments to the executive on an after-tax basis.

    The annual incentive plan, executive restricted stock plan grants, 1999
stock option plan, officers' retirement plan, executive life insurance plan and
deferred compensation plan maintained by CTG Resources or its subsidiaries
contain provisions relating to change in control. Under the annual incentive
plan, after a change of control, employees, including executive officers,
participating in the plan, whether or not the employees are terminated, will
have a right to an immediate cash payment of their annual awards, on a prorated
basis, based on the annual rate of their base salary immediately prior to the
change in control and on the assumption that established targets at the 100%
performance level for the year had been met. Any such payment will reduce the
amount of prorated bonus paid to the participant in the year in which the change
in control occurs under his or her change-in-control employment agreement
described above. Under the executive restricted stock plan, outstanding
restricted stock grants will become immediately vested on the occurrence of a
change in control, except that for participants who do not have a
change-in-control employment agreement described above, the right to restricted
shares will be forfeited to the extent the value of full vesting would give rise
to an excise tax under Section 4999 of the Internal Revenue Code and such
forfeiture results in an increase in the aggregate benefits and payments to the
participant on an after-tax basis. Under the 1999 stock option plan, outstanding
options which are not vested and exercisable will become immediately exercisable
and vested in full on the occurrence of a change in control, and all outstanding
options will be canceled at the time of change in control in exchange for a cash
payment of the excess of the fair

                                       49
<PAGE>
market value of the stock (which in the case of the merger would be $41.00 per
share) over the exercise price. Under the officers' retirement plan, the accrued
benefit of each individual participating therein will become fully vested on the
occurrence of a change in control. Under the deferred compensation plan,
following a change in control a participant may elect to have his or her
elective deferrals invested at the 30-Year Treasury Bond rate in lieu of other
deemed investment alternatives and to have his or her employer matching
contributions credits invested at the 30-Year Treasury Bond rate or in
accordance with other investment alternatives in lieu of a deemed investment in
employer stock. Under the executive life insurance plan, after a change in
control, coverage provided thereunder will continue in effect if a participant
terminates his or her employment prior to age 62 until the participant attains
age 62 or his or her earlier death or, in certain cases, for the balance of 10
years from the inception of the program. The completion of the merger will
constitute a "change in control" under all the plans and grants described above.

    We estimate that if the merger were to occur on July 1, 2000 and all
participants, including executive officers, covered by the plans and agreements
described above were terminated immediately thereafter, based on currently
effective compensation levels, valuation factors, interest rates and a CTG
Resources share price of $41.00, the aggregate after-tax cost of the additional
benefits payable to participants under the above plans and agreements (other
than the change-in-control employment agreement applicable to Mr. Marquardt) as
a result of the merger and subsequent termination would be approximately
$10,481,500.

    INDEMNIFICATION.  Pursuant to the merger agreement, from and after the
effective time of the merger, Energy East and the surviving company will, to the
fullest extent permitted by applicable law, indemnify, defend and hold harmless
each individual who, prior to the effective time of the merger, was an officer,
director or employee of CTG Resources or any of its subsidiaries against all
losses, expenses (including reasonable attorneys' fees and expenses), claims,
damages or liabilities or, subject to various restrictions, amounts paid in
settlement, arising out of actions or omissions occurring at or prior to the
effective time of the merger that are at least in part (1) based on the fact
that that individual has ever been a director, officer or employee of such
entity or (2) based on the transactions contemplated by the merger agreement.

    In addition, for six years after the effective time, Energy East will either
(1) maintain policies of liability insurance for the benefit of those persons
who currently are covered by CTG Resources's existing directors' and officers'
liability insurance policies or (2) provide tail coverage for those persons. In
either case, the terms of the coverage will be at least as favorable as the
terms of the current insurance coverage. Energy East will not, however, be
required to expend in any year more than 200% of the annual aggregate premiums
that CTG Resources currently pays.

MATERIAL FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

    The following discussion is a summary description of the material U.S.
federal income tax consequences of the merger applicable to CTG Resources
shareholders. This discussion is for general information only and does not
purport to consider all aspects of U.S. federal income taxation that may be
relevant to a CTG Resources shareholder. For example, this discussion does not
address the effect, if any, of the Foreign Investment in Real Property Tax Act
on non-U.S. persons who hold CTG Resources shares. This discussion is based upon
the provisions of the Internal Revenue Code, existing regulations, and
administrative and judicial interpretations of the Internal Revenue Code, all as
in effect as of the date hereof and all of which are subject to change (possibly
with retroactive effect). This discussion applies only to CTG Resources
shareholders who hold their CTG Resources shares as

                                       50
<PAGE>
capital assets within the meaning of Section 1221 of the Internal Revenue Code
and does not apply to the following:

    - shareholders who received their CTG Resources shares pursuant to the
      exercise of employee stock options or similar securities or otherwise as
      compensation;

    - shareholders who hold their CTG Resources shares as part of a "straddle,"
      "hedge," "conversion transaction," "synthetic security" or other
      integrated investment;

    - shareholders who exercise dissenters' rights of appraisal;

    - shareholders (including, without limitation, financial institutions,
      insurance companies, tax-exempt organizations, dealers or traders in
      securities and shareholders subject to the alternative minimum tax) who
      may be subject to special rules;

    - shareholders whose functional currency is not the U.S. dollar; or

    - shareholders who, for U.S. federal income tax purposes, are non-resident
      alien individuals, foreign corporations, foreign partnerships, or foreign
      estates or trusts.

    This discussion also does not consider the effect of any foreign, state or
local laws or any U.S. federal laws other than those pertaining to the income
tax.

    THE INDIVIDUAL CIRCUMSTANCES OF EACH CTG RESOURCES SHAREHOLDER MAY AFFECT
THE TAX CONSEQUENCES OF THE MERGER TO SUCH CTG RESOURCES SHAREHOLDER. THE
PARTICULAR FACTS OR CIRCUMSTANCES OF A CTG RESOURCES SHAREHOLDER THAT MAY SO
AFFECT THE CONSEQUENCES ARE NOT DISCUSSED HERE. ACCORDINGLY, YOU SHOULD CONSULT
YOUR TAX ADVISOR TO DETERMINE THE TAX EFFECT TO YOU OF THE MERGER, INCLUDING THE
APPLICATION AND EFFECT OF FOREIGN, OR U.S. FEDERAL, STATE, LOCAL OR OTHER TAX
LAWS. NON-U.S. SHAREHOLDERS, IF ANY, WHO HOLD OR HAVE HELD (DIRECTLY,
CONSTRUCTIVELY, OR BY ATTRIBUTION) MORE THAN 5% OF THE OUTSTANDING CTG RESOURCES
SHARES SHOULD CONSULT THEIR TAX ADVISORS REGARDING THE CONSEQUENCES TO THEM OF
THE MERGER UNDER THE FOREIGN INVESTMENT IN REAL PROPERTY TAX ACT, INCLUDING ANY
TAX FILING REQUIREMENTS THAT MAY APPLY.

    The completion of the merger is contingent upon the receipt by:

    - Energy East of an opinion from its attorneys to the effect that the merger
      will be treated as a reorganization within the meaning of Section 368(a)
      of the Internal Revenue Code; and

    - CTG Resources of an opinion from its attorneys to the effect that the
      merger will be treated as a reorganization within the meaning of Section
      368(a) of the Internal Revenue Code.

    The opinions will be based upon certain customary assumptions and
representations of fact, including representations of fact contained in
certificates of officers of Energy East, CTG Resources and others. No ruling has
been or will be sought from the Internal Revenue Service as to the U.S. federal
income tax consequences of the merger, and the opinions of counsel are not
binding upon the Internal Revenue Service or any court. Accordingly, there can
be no assurances that the Internal Revenue Service will not contest the
conclusions expressed in the opinions or that a court will not sustain such
contest.

    The following discussion of U.S. federal income tax consequences of the
merger to CTG Resources shareholders assumes that the merger will qualify as a
"reorganization" within the meaning of Section 368(a) of the Internal Revenue
Code. As discussed below, the U.S. federal income tax consequences of the merger
to a CTG Resources shareholder depend on the form of consideration received by
the shareholder.

                                       51
<PAGE>
    SHAREHOLDERS WHO RECEIVE SOLELY ENERGY EAST COMMON STOCK. A CTG Resources
shareholder who exchanges CTG Resources shares solely for Energy East shares
will not recognize any gain or loss on that exchange, except to the extent the
shareholder receives cash in lieu of fractional shares of Energy East (as
discussed below). The aggregate adjusted tax basis of Energy East shares
received will equal the CTG Resources shareholder's aggregate adjusted tax basis
in the CTG Resources shares surrendered (reduced by the tax basis allocable to
any fractional shares of Energy East received in the merger). The holding period
of the Energy East shares received pursuant to the merger will include the
holding period of the CTG Resources shares surrendered.

    SHAREHOLDERS WHO RECEIVE CASH AND ENERGY EAST COMMON STOCK.  If the
consideration received in the merger by a CTG Resources shareholder consists of
part cash and part Energy East shares and the shareholder's adjusted basis in
the CTG Resources shares surrendered in the transaction is less than the sum of
the fair market value, as of the date of the merger, of the Energy East shares
and the amount of cash received by the shareholder, then the shareholder will
recognize a gain. This recognized gain will equal the lesser of (1) the sum of
the amount of cash and the fair market value, as of the date of the merger, of
the Energy East shares received, minus the adjusted basis of the CTG Resources
shares surrendered in exchange therefor, and (2) the amount of cash received by
the shareholder in the exchange. However, if a CTG Resources shareholder's
adjusted basis in the CTG Resources shares surrendered in the transaction is
greater than the sum of the amount of cash and the fair market value of the
Energy East shares received, the CTG Resources shareholder's loss will not be
currently allowed or recognized for U.S. federal income tax purposes.

    In the case of a CTG Resources shareholder who recognizes gain on the
exchange, if the exchange sufficiently reduces the shareholder's proportionate
stock interest (as discussed below), the gain will be characterized as a capital
gain. If the exchange does not sufficiently reduce the shareholder's
proportionate stock interest, such gain will be taxable as a dividend to the
extent of the shareholder's ratable share of available earnings and profits (and
the remainder, if any, of such recognized gain will be capital gain).

    The determination of whether the exchange sufficiently reduces a CTG
Resources shareholder's proportionate stock interest will be made in accordance
with Section 302 of the Internal Revenue Code, taking into account the stock
ownership attribution rules of Section 318 of the Internal Revenue Code. Under
those rules, for purposes of determining whether the exchange sufficiently
reduces a shareholder's proportionate stock interest, a CTG Resources
shareholder is treated as if (1) all such shareholder's CTG Resources shares
were first exchanged in the merger for Energy East shares and (2) a portion of
those Energy East shares were then redeemed for the cash actually received in
the merger. The CTG Resources shareholder's hypothetical stock interest in
Energy East (both actual and constructive) after hypothetical step (2) is
compared to such CTG Resources shareholder's hypothetical stock interest in
Energy East (both actual and constructive) after hypothetical step (1). Dividend
treatment will apply unless either the shareholder's stock interest in Energy
East has been completely terminated, there has been a "substantially
disproportionate" reduction in the shareholder's stock interest in Energy East
(I.E., such interest after hypothetical step (2) is less than 80% of the
interest after hypothetical step (1)), or the exchange is not "essentially
equivalent to a dividend." While the determination is based on a CTG Resources
shareholder's particular facts and circumstances, the Internal Revenue Service
has indicated in published rulings that a distribution is not "essentially
equivalent to a dividend" and will therefore result in capital gain treatment if
the distribution results in any actual reduction in the stock interest of an
extremely small minority shareholder in a publicly held corporation and the
shareholder exercises no control with respect to corporate affairs.

                                       52
<PAGE>
    BECAUSE THE DETERMINATION OF WHETHER A PAYMENT WILL BE TREATED AS HAVING THE
EFFECT OF THE DISTRIBUTION OF A DIVIDEND GENERALLY WILL DEPEND UPON THE FACTS
AND CIRCUMSTANCES OF EACH CTG RESOURCES SHAREHOLDER, CTG RESOURCES SHAREHOLDERS
ARE STRONGLY ADVISED TO CONSULT THEIR OWN TAX ADVISORS REGARDING THE TAX
TREATMENT OF CASH RECEIVED IN THE MERGER, INCLUDING THE APPLICATION OF THE
CONSTRUCTIVE OWNERSHIP RULES OF THE INTERNAL REVENUE CODE AND THE EFFECT OF ANY
TRANSACTIONS IN ENERGY EAST SHARES OR CTG RESOURCES SHARES BY THE CTG RESOURCES
SHAREHOLDER.

    The basis of a CTG Resources shareholder who receives cash and Energy East
shares in the merger in the Energy East shares received will equal such
shareholder's adjusted basis in the shareholder's CTG Resources shares increased
by any gain recognized as a result of the merger and reduced by the amount of
cash received in the merger. The holding period of the Energy East shares
received will include the holding period of the CTG Resources shares
surrendered.

    SHAREHOLDERS WHO RECEIVE SOLELY CASH.  The exchange of CTG Resources shares
solely for cash generally will result in recognition of gain or loss by the
shareholder in an amount equal to the difference between the amount of cash
received and the shareholder's adjusted tax basis in the CTG Resources shares
surrendered. The gain or loss recognized will be long-term capital gain or loss
if the shareholder's holding period for the CTG Resources shares surrendered
exceeds one year. There are limitations on the extent to which shareholders may
deduct capital losses from ordinary income.

    If a CTG Resources shareholder who receives only cash in exchange for all
such shareholder's CTG Resources shares constructively owns CTG Resources shares
before the merger or actually or constructively owns Energy East shares after
the merger (as the result of constructive ownership of CTG Resources shares that
are exchanged for Energy East shares in the merger, prior actual or constructive
ownership of Energy East shares or otherwise), all or a portion of the cash
received by the shareholder may, in certain circumstances, be taxed as a
dividend, and such shareholders should consult their tax advisors to determine
the amount and character of the income recognized in connection with the merger.

    DISSENTING CTG RESOURCES SHAREHOLDERS.  CTG Resources shareholders who elect
to exercise their right to dissent from the merger pursuant to the Connecticut
Business Corporation Act with respect to all of their CTG Resources shares and
to be paid the fair value of those shares will recognize gain or loss. The
amount of this gain or loss will generally be equal to the difference between
the amount of cash received and the shareholder's adjusted tax basis in the CTG
Resources shares transferred pursuant to the exercise of dissenters' rights.
Whether this gain is treated as capital gain or as dividend income and whether
any gain subject to capital treatment is long term or short term will generally
be based on principles similar to the principles described in the section above
applicable to CTG Resources shareholders who participate in the merger and
receive solely cash in exchange for their surrendered CTG Resources shares. See
"-- Shareholders Who Receive Solely Cash." CTG Resources shareholders who elect
to exercise their right to dissent from the merger should consult their tax
advisors as to the tax consequences to them of the merger and the exercise of
dissenters' rights, including the timing of gain or loss recognition and the
treatment of any interest that may be awarded pursuant to an appraisal
proceeding.

    CASH RECEIVED IN LIEU OF FRACTIONAL SHARES.  A CTG Resources shareholder who
receives cash in lieu of a fractional Energy East share will be treated as
having first received such fractional Energy East share in the merger and then
as having received cash in exchange for the fractional share interest. Thus,
such a CTG Resources shareholder generally will recognize gain or loss in an
amount equal to the difference between the amount of cash received in lieu of
the fractional Energy East share and the portion of the basis in the CTG
Resources shares allocable to that fractional interest.

                                       53
<PAGE>
    SPECIAL RULES FOR SHAREHOLDERS THAT ARE CORPORATIONS.  To the extent that
cash received in exchange for CTG Resources shares is taxable as a dividend (as
described above) to a CTG Resources shareholder that is a corporation, that
shareholder will be (1) eligible for a dividends received deduction (subject to
applicable limitations) and (2) generally subject to the "extraordinary
dividend" provisions of the Internal Revenue Code. Under recently enacted
legislation, any such cash that is taxable as a dividend to a corporate
shareholder will constitute an extraordinary dividend. Consequently, the
nontaxed portion of any such dividend will reduce the adjusted tax basis of a
CTG Resources shareholder that is a corporation in the Energy East shares
received in the merger, but not below zero, and will thereafter be taxable as
capital gain.

    INCOME TAX RATES.  Capital gain recognized in the merger by individuals and
certain other noncorporate CTG Resources shareholders who have held their CTG
Resources shares for more than one year generally will be subject to a maximum
U.S. federal income tax rate of 20%. Gain or dividend income otherwise
recognized by CTG Resources shareholders generally will be subject to a (1)
maximum 39.6% U.S. federal income tax rate for individuals and certain other
noncorporate shareholders, or (2) maximum 35% U.S. federal income tax rate for
corporations.

    MATERIAL FEDERAL INCOME TAX CONSEQUENCES TO ENERGY EAST, CTG RESOURCES AND
OAK MERGER CO. Assuming that the merger is treated as a reorganization, none of
Energy East, CTG Resources or Oak Merger Co. will recognize gain or loss as a
result of the merger.

    BACKUP WITHHOLDING.  Payments in connection with the merger may be subject
to "backup withholding" at a rate of 31%, unless a CTG Resources shareholder (1)
provides a correct taxpayer identification number (which, for an individual
shareholder, is the shareholder's social security number) and any other required
information to the paying agent, or (2) is a corporation or comes within certain
exempt categories and, when required, demonstrates that fact and otherwise
complies with applicable requirements of the backup withholding rules. A CTG
Resources shareholder who does not provide a correct taxpayer identification
number may be subject to penalties imposed by the Internal Revenue Service. Any
amount paid as backup withholding does not constitute an additional tax and will
be creditable against the shareholder's U.S. federal income tax liability. Each
CTG Resources shareholder should consult with his own tax advisor as to his
qualification for exemption from backup withholding and the procedure for
obtaining such exemption. CTG RESOURCES SHAREHOLDERS MAY PREVENT BACKUP
WITHHOLDING BY COMPLETING A SUBSTITUTE FORM W-9 AND SUBMITTING IT TO THE PAYING
AGENT FOR THE MERGER WHEN THEY SUBMIT THEIR CTG RESOURCES SHARE CERTIFICATES.

CTG RESOURCES DIVIDEND REINVESTMENT PLAN

    Some CTG Resources shareholders hold all or part of their CTG Resources
shares under CTG Resources's Dividend Reinvestment Plan. The CTG Resources
Dividend Reinvestment Plan will be terminated upon the completion of the merger.
CTG Resources shareholders who hold CTG Resources shares under this plan will
have the option to receive cash or Energy East shares in exchange for their CTG
Resources shares held under the plan.

         DISSENTERS' RIGHTS OF APPRAISAL OF CTG RESOURCES SHAREHOLDERS

    If you hold CTG Resources shares and do not wish to accept the merger
consideration, then Sections 33-855 through 33-872 of the Connecticut Business
Corporation Act provide you with an alternative. Under these sections, you have
a right to dissent from the merger, and can choose to be paid the fair value of
your CTG Resources shares once the merger is completed, provided you follow the
procedures outlined in the statute. The complete text of these sections is
included in Appendix C to this proxy statement/prospectus.

    If you wish to exercise your dissenters' rights of appraisal or to preserve
the right to do so, you should carefully review Appendix C and seek the advice
of counsel. If you do not comply with the deadlines and procedures specified in
the Connecticut Business Corporation Act, you may lose your dissenters' rights
of appraisal. To exercise these rights, you must satisfy each of the following
conditions:

    - you must not vote in favor of the merger agreement; and

    - you must deliver to the Secretary of CTG Resources, before the vote on the
      merger at the special meeting, a written notice of your intent to demand
      payment of the fair value of your shares.

    You must deliver the notice of intent even if you submit a proxy or vote
against the merger. MERELY VOTING AGAINST, ABSTAINING FROM VOTING OR FAILING TO
VOTE IN FAVOR OF ADOPTION OF THE MERGER WILL NOT CONSTITUTE A NOTICE OF INTENT
TO EXERCISE DISSENTERS' RIGHTS OF APPRAISAL UNDER THE CONNECTICUT BUSINESS
CORPORATION ACT.

    If CTG Resources shareholders approve the merger at the special meeting and
you meet the requirements above, then CTG Resources will send you, within ten
days of the approval of the merger, a written dissenters' notice to be used to
demand payment for your shares. The dissenters' notice will:

    - state where the payment demand must be sent and when and where
      certificates for certificated shares must be deposited;

    - inform holders of uncertificated shares to what extent transfer of the
      shares will be restricted after the payment demand is received;

    - supply a form for demanding payment that includes the date of the first
      announcement to the news media or to shareholders of the terms of the
      merger agreement and require that each shareholder asserting dissenters'
      rights certify whether or not he acquired beneficial ownership of the
      shares before that date;

    - set a date by which CTG Resources must receive the payment demand, which
      may not be fewer than 30 nor more than 60 days after the written
      dissenters' notice is delivered by CTG Resources; and

    - be accompanied by a copy of Sections 33-855 through 33-872 of the
      Connecticut Business Corporation Act (these are the sections that discuss
      dissenters' rights).

    Under Section 33-863(a) of the Connecticut Business Corporation Act, if you
receive a dissenters' notice and wish to exercise your dissenters' rights of
appraisal, you must:

    - demand payment for your shares;

    - certify that you acquired beneficial ownership of your shares (generally,
      the right to vote or enter into an arrangement or agreement for the
      purpose of voting your shares, the right to acquire shares and the right
      to dispose of shares) before the date of the first announcement to the
      news media or to the shareholders of the terms of the merger agreement as
      set forth in the dissenters' notice; and

                                       55
<PAGE>
    - deposit the certificate or certificates representing your shares in
      accordance with the terms of the dissenters' notice.

    IF YOU ARE CONSIDERING SEEKING DISSENTERS' RIGHTS OF APPRAISAL, YOU SHOULD
BE AWARE THAT THE FAIR VALUE OF YOUR SHARES AS DETERMINED UNDER THE APPLICABLE
PROVISIONS OF THE CONNECTICUT BUSINESS CORPORATION ACT COULD BE GREATER THAN,
THE SAME AS OR LESS THAN THE MERGER CONSIDERATION.

    After CTG Resources receives a valid, timely and complete payment demand, or
upon completion of the merger, CTG Resources will pay to each dissenting
shareholder the amount it estimates to be the fair value of the dissenting
shareholder's shares, plus accrued interest, as provided in Section 33-865(a) of
the Connecticut Business Corporation Act. That payment will be accompanied by:

    - CTG Resources's balance sheet as of the end of a fiscal year ending not
      more than 16 months before the date of payment, an income statement for
      that year, a statement of changes in shareholders' equity for that year
      and the latest available interim financial statements, if any;

    - a statement of CTG Resources's estimate of the fair value of the shares;

    - an explanation of how the accrued interest was calculated;

    - a statement of the shareholders' right to demand payment under Section
      33-868 of the Connecticut Business Corporation Act; and

    - a copy of Sections 33-855 through 33-872 of the Connecticut Business
      Corporation Act.

    If the merger does not take place within 60 days after the date set for
demanding payment and depositing certificates representing dissenting
shareholders' shares, CTG Resources will return the deposited certificates and
release any transfer restrictions that may have been imposed on uncertificated
shares. If the merger is completed after the return of the deposited shares and
the release of transfer restrictions, CTG Resources will send a new dissenters'
notice and repeat the payment-demand procedure.

    Under Section 33-868 of the Connecticut Business Corporation Act, you may
send to CTG Resources your own estimate of the fair value of your shares and the
amount of any interest due, and demand payment of the difference between your
estimate and the amount paid, if any, by CTG Resources in the following cases:

    - if you believe that the amount paid by CTG Resources is less than the fair
      value of your shares or that the interest due is incorrectly calculated;

    - if CTG Resources fails to make payment within 60 days after the date set
      in the dissenters' notice for demanding payment (except if the payment is
      withheld to holders of shares who acquired the shares after the
      announcement of the merger); or

    - if the merger is not completed, and CTG Resources does not return the
      deposited certificates or release any transfer restrictions imposed on
      uncertificated shares within 60 days after the date set in the dissenters'
      notice for demanding payment.

    If you do not demand payment of the difference between your estimate of the
fair value of your shares, plus interest, and the amount paid by CTG Resources
within 30 days after CTG Resources made or offered to make that payment, you
will lose your right to demand payment of any such difference.

    Under Sections 33-871(a) and (b) of the Connecticut Business Corporation
Act, if your demand for payment of your estimate remains unsettled, CTG
Resources will commence a proceeding within 60 days after receipt of your demand
for payment and petition the superior court for the judicial district where CTG
Resources's principal office is located to determine the fair value of your
shares

                                       56
<PAGE>
and accrued interest. If CTG Resources does not timely commence this proceeding,
CTG Resources must pay you the unsettled amount that you demanded.

    If this proceeding takes place, CTG Resources will make all dissenting
shareholders whose demands remain unsettled (even if they are not residents of
Connecticut) parties to the proceeding, and all parties will be served with a
copy of the petition. The court may appoint appraisers who will receive evidence
and recommend a decision on the question of fair value. If the court finds that
the amount CTG Resources paid is less than the fair value of a dissenting
shareholder's shares, plus accrued interest, the court will order CTG Resources
to pay the difference to the dissenting shareholder.

    The court will determine all costs of the proceeding, including the
reasonable compensation and expenses of court-appointed appraisers. CTG
Resources generally will pay these costs, but the court may order the dissenting
shareholders to pay some of them, in amounts the court finds equitable, if the
court finds that the shareholders acted arbitrarily, vexatiously or not in good
faith in demanding payment.

    If you give notice of your intent to demand dissenters' rights for your
shares under the applicable provisions of the Connecticut Business Corporation
Act but fail to return the dissenters' notice or withdraw or lose your right to
demand payment, your shares will be converted into the right to receive the cash
consideration in the merger. See "The Merger Agreement -- Conversion of CTG
Resources Shares."

    The foregoing is only a summary of the applicable provisions of the
Connecticut Business Corporation Act and is qualified in its entirety by
reference to the full text of such provisions, which is included in Appendix C.

                              THE MERGER AGREEMENT

    THE FOLLOWING DESCRIPTION OF THE MERGER AGREEMENT IS ONLY A SUMMARY. WE URGE
YOU TO READ THE ACTUAL MERGER AGREEMENT, A COPY OF WHICH IS ATTACHED AS APPENDIX
A TO THIS PROXY STATEMENT/PROSPECTUS.

GENERAL

    The merger agreement provides that CTG Resources will merge with and into
Oak Merger Co., a wholly owned subsidiary of Energy East. Oak Merger Co. will
survive the merger as a wholly owned subsidiary of Energy East and will be
renamed "CTG Resources, Inc."

    The closing of the merger will occur on the second business day immediately
following the date upon which all conditions to the merger have been satisfied
or waived, or at such other time as the parties agree. At the closing of the
merger, the parties will deliver a certificate of merger to the Secretary of the
State of Connecticut for filing. The merger will become effective upon the
filing of this certificate or at such later time as may be set forth in the
certificate. We currently expect that the closing of the merger will take place
in the middle of the year 2000.

CORPORATE GOVERNANCE MATTERS

    DIRECTORS.  After the merger becomes effective, the board of directors of
the surviving company will consist of the current directors of Oak Merger Co.
and Mr. Marquardt. These directors will hold office until their successors are
duly elected or appointed and qualified. In addition, pursuant to the merger
agreement, Energy East will add a member to its board of directors. This seat
will be filled by one of the current directors of CTG Resources, as designated
by CTG Resources and reasonably acceptable to Energy East. The additional
director will not be an employee of the surviving company.

    OFFICERS.  Once the merger becomes effective, Mr. Marquardt will be the
president and chief executive officer of the surviving company (which will be a
subsidiary of Energy East). He will also hold officer positions in other Energy
East subsidiaries, as specified in an employment agreement that he and Energy
East have executed. The other officers of the surviving company will be the same
individuals who hold the officer positions of Oak Merger Co. immediately prior
to the effective time of the merger. All officers will hold their positions
until their successors are duly elected or appointed and qualified.

CONVERSION OF CTG RESOURCES SHARES

    MERGER CONSIDERATION.  At the effective time of the merger, all outstanding
CTG Resources shares (other than those that are held by CTG Resources
shareholders who have not voted in favor of the merger agreement and have
properly demanded dissenters' rights) will be converted into the right to
receive the merger consideration. Each CTG Resources shareholder has a right to
make an election as to the form in which he would like to receive the merger
consideration, which may be subject to proration or adjustment based on tax
considerations as explained below. CTG Resources shareholders can elect to
receive cash, Energy East shares, or a combination of cash and Energy East
shares. The cash consideration amounts to $41.00 in cash, without interest, per
share. The stock consideration is a number of Energy East shares for each CTG
Resources share that will vary depending on the Average Market Price. If the
Average Market Price is equal to or more than $23.67 per share and equal to or
less than $30.13 per share, then a CTG Resources share will be exchanged for
$41.00 worth of Energy East shares. If the Average Market Price is less than
$23.67, then a CTG Resources share will be exchanged for 1.7320 Energy East
shares, irrespective of the value of those shares. Finally, if the Average
Market Price is greater than $30.13 per share, then a CTG Resources share will
be exchanged for 1.3609 Energy East shares, again irrespective of the value of
those shares. If a CTG Resources shareholder wants a combination of cash and
Energy East shares, he must designate how many of his

                                       58
<PAGE>
CTG Resources shares he would like to convert into the $41.00 in cash and how
many he would like to convert into Energy East shares.

    As of the effective time of the merger, no CTG Resources shares will be
outstanding; they will all be automatically canceled and retired. Each CTG
Resources shareholder will cease to have any shareholder rights, except either
the right to receive the merger consideration -- cash, Energy East shares or a
combination of the two -- or the right to dissent. CTG Resources shareholders
who have properly demanded dissenters' rights will have those rights that are
granted by Connecticut law.

    OVERSUBSCRIPTION OF CASH OR STOCK.  Subject to an adjustment for tax reasons
(as described below), 55% of all outstanding CTG Resources shares will be
converted into cash, and 45% will be converted into Energy East shares.

    CTG Resources shareholders, as a group, may submit elections to convert more
than 55% of the outstanding CTG Resources shares into cash or more than 45% into
Energy East shares. If either cash or Energy East shares is oversubscribed, then
an equitable PRO RATA adjustment will be made to ensure that 55% of the
outstanding CTG Resources shares are converted into cash and 45% are converted
into Energy East shares. For example, if cash is oversubscribed, each CTG
Resources share as to which an election was submitted to be converted into the
$41.00 in cash will, instead, be converted into an amount of cash that is less
than $41.00 and a number of Energy East shares to make up the difference.
Similarly, if Energy East shares are oversubscribed, each CTG Resources share as
to which an election was submitted to be converted into a certain number of
Energy East shares will, instead, be converted into fewer Energy East shares and
an amount of cash to cover the difference.

    NO FRACTIONAL SHARES.  No fractional Energy East shares will be issued in
the merger. CTG Resources shareholders will receive a cash payment in lieu of
fractional Energy East shares. This cash will come from an exchange agent's
open-market sales of the aggregate fractional Energy East shares.

    ADJUSTMENT TO PER SHARE ENERGY EAST STOCK AMOUNT.  If, prior to the
effective time of the merger, Energy East pays an extraordinary dividend, enters
into a merger or consolidation, or changes the number of outstanding Energy East
shares through a stock split, stock dividend or similar transaction, then the
calculation of the number of Energy East shares to be received in the merger
will be adjusted to reflect this transaction.

    TAX ADJUSTMENT.  Energy East and CTG Resources intend for the merger to be a
"reorganization" within the meaning of the Internal Revenue Code and, therefore,
tax free for those shareholders who receive only Energy East shares in the
transaction. Under the Internal Revenue Code, however, the merger might not be a
reorganization if, on the closing date of the merger, the total value of the
Energy East shares that CTG Resources shareholders receive is less than 45% of
the value of the total consideration -- including Energy East shares, cash and
any other amounts treated as consideration in connection with the merger for
purposes of the Internal Revenue Code -- that CTG Resources shareholders
(including shareholders who exercise dissenters' rights) receive in connection
with the merger. To prevent this from happening, if the value of the Energy East
shares received would otherwise be less than 45% of the value of the total
consideration, the number of CTG Resources shares that will be converted into
Energy East shares will be increased, and the number of CTG Resources shares
converted into cash will be correspondingly decreased.

    EXCHANGE AGENT.  Energy East will deposit with an exchange agent
certificates evidencing the Energy East shares issuable and cash payable in
exchange for outstanding CTG Resources shares.

    ELECTION PROCEDURE; EXCHANGE OF CERTIFICATES.  Copies of the form of
election will be mailed to record holders of CTG Resources shares not less than
30 days prior to the effective time of the merger and made available to persons
who become record holders after this mailing but not later than seven business
days prior to the effective time of the merger. To be effective, a form of
election must be:

                                       59
<PAGE>
    - properly completed, signed and submitted to the exchange agent;

    - accompanied by the CTG Resources share certificates as to which the
      election is being made (or an appropriate guarantee of delivery of such
      certificates as provided in the merger agreement); and

    - received by the exchange agent before the election deadline, which is 5:00
      p.m., New York City Time, on the second day after the effective time of
      the merger.

    Energy East has the right to determine whether a CTG Resources shareholder
has properly completed, signed, and submitted (or revoked) a form of election
and to disregard immaterial defects in the form of election. Energy East may
delegate this right to the exchange agent. Neither Energy East nor the exchange
agent is under any obligation to notify any person of any defect in a form of
election submitted to the exchange agent. The exchange agent will also make all
computations that the merger agreement requires, and all such computations will
be conclusive and binding on CTG Resources shareholders. Any form of election
may be revoked prior to the deadline for submitting elections.

    A CTG Resources shareholder who submits an untimely or improper form of
election will be deemed not to have made an election. CTG Resources may treat
that shareholder's shares as shares that the shareholder elected to exchange for
cash or Energy East shares, at CTG Resources's discretion.

    DISSENTERS' SHARES.  CTG Resources shareholders who decide to pursue their
rights to dissent under Connecticut law will lose their right to receive the
merger consideration; they will have only those rights that are granted by
applicable Connecticut law. If, however, after the effective time of the merger,
a holder withdraws or loses his right to dissent, his CTG Resources shares will
be treated as if he had elected to receive $41.00 in cash per CTG Resources
share. CTG Resources will promptly notify Energy East if it receives any written
demands for payment of the fair value of outstanding CTG Resources shares and
withdrawals of such demands. The surviving company will make all these payments.

    EXCHANGE AND PAYMENT PROCEDURES.  Promptly after the effective time of the
merger, the exchange agent will mail to each record holder of a certificate
representing CTG Resources shares that have been converted into the right to
receive merger consideration:

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

    - instructions explaining what the shareholders must do to effect the
      surrender of the CTG Resources stock certificates and receive the merger
      consideration.

    After a shareholder submits his stock certificates, a letter of transmittal
and other documents that may be required, the shareholder will have the right to
receive cash, a certificate representing Energy East shares, or both. The merger
consideration may be delivered to someone who is not listed in CTG Resources's
transfer records if he presents a CTG Resources share certificate to the
exchange agent along with all documents required to evidence that a transfer of
the certificate has been made to him and any applicable stock transfer taxes
have been paid. Until surrender, each certificate (other than those that are
held by CTG Resources shareholders who have not voted in favor of the merger and
have properly demanded dissenters' rights) will be deemed at any time after the
effective time of the merger to represent only the right to receive the merger
consideration upon surrender.

    PAYMENTS FOLLOWING SURRENDER.  Until they have surrendered their
certificates, holders of certificates who elect to receive Energy East shares
will not receive:

                                       60
<PAGE>
    - dividends and other distributions with respect to Energy East shares that
      they are entitled to pursuant to the merger and that are declared or made
      with a record date after the effective time; or

    - cash payment in place of fractional Energy East shares.

    At the time of surrender, CTG Resources shareholders will receive the cash
payable in place of fractional Energy East shares to which the CTG Resources
shareholders are entitled under the merger agreement and the dividends or other
distributions that have been paid to Energy East shareholders if such
distributions had a record date after the effective time. These shareholders
will also be paid on the appropriate payment date the amount of dividends or
other distributions with a record date after the effective time (but prior to
surrender) and a payment date subsequent to surrender.

    SHAREHOLDERS SHOULD NOT FORWARD CERTIFICATES TO THE EXCHANGE AGENT, ENERGY
EAST OR CTG RESOURCES UNTIL THEY HAVE RECEIVED A FORM OF ELECTION. SHAREHOLDERS
SHOULD NOT RETURN CERTIFICATES WITH THE ENCLOSED PROXY. A FORM OF ELECTION AND
COMPLETE INSTRUCTIONS FOR PROPERLY MAKING AN ELECTION TO RECEIVE CASH, ENERGY
EAST SHARES OR A COMBINATION OF CASH AND ENERGY EAST SHARES WILL BE MAILED TO
SHAREHOLDERS UNDER SEPARATE COVER BEFORE THE ANTICIPATED DAY OF THE CLOSING OF
THE MERGER, WHICH IS CURRENTLY EXPECTED TO BE IN THE MIDDLE OF THE YEAR 2000.

    The representations and warranties made by the parties to the merger
agreement will not survive the merger, but they form the basis of conditions to
the obligations of Energy East and CTG Resources.

COVENANTS

    MUTUAL COVENANTS.  Under the merger agreement, the parties agreed that,
during the period from the date of the merger agreement until the effective time
of the merger, except as otherwise permitted in the merger agreement or by
written consent of the parties, they will comply with the following covenants:

    - they will coordinate dividend policies prior to the closing date of the
      merger, so that differences in the timing of record, declaration or
      payment dates will not adversely affect either Energy East shareholders or
      CTG Resources shareholders;

    - they and their subsidiaries will not amend their certificates of
      incorporation, by-laws or other organizational documents, or take or fail
      to take any other action, in such a way that would reasonably be expected
      to prevent, materially impede or interfere with the merger;

    - they will not take any actions that would be reasonably likely to affect
      adversely the status of the merger as a reorganization within the meaning
      of Section 368(a) of the Internal Revenue Code; in fact, each party agreed
      to use all reasonable efforts to obtain this status;

    - they will confer on a regular and frequent basis with representatives of
      the other party to discuss, subject to applicable law, material
      operational matters and the general status of their ongoing operations;
      promptly notify the other party of any significant changes in their
      business, properties, assets, condition, results of operations or
      prospects; advise the other party of any change or event that has had or
      is reasonably likely to result in a material adverse effect on

                                       62
<PAGE>
      them; and promptly provide the other party with copies of all filings with
      governmental authorities in connection with the merger agreement;

    - they and their subsidiaries will use commercially reasonable efforts to
      obtain all necessary consents to complete the merger, promptly notify the
      other party of any failure or prospective failure to obtain these
      consents, and, if requested by the other party, will provide copies of all
      the consents that have been obtained;

    - they and their subsidiaries will not willfully take any action that is
      reasonably likely to result in a material breach of the merger agreement
      or in any of their representations and warranties being untrue on and as
      of the closing date of the merger; and

    - they will take all necessary steps within their control to exempt the
      merger from, or, if necessary, challenge the validity or applicability of,
      any applicable takeover law.

    COVENANTS OF ENERGY EAST.  Except as provided in the disclosure schedules to
the merger agreement, Energy East agreed that neither it nor any of its
subsidiaries will enter into a transaction that would require a governmental
filing or consent that would reasonably be expected to prevent or delay
materially the effective time of the merger beyond December 29, 2000.

    COVENANTS OF CTG RESOURCES.  CTG Resources agreed that, until the effective
time of the merger or the termination of the merger agreement (except as
disclosed in the schedules to the merger agreement), CTG Resources and its
subsidiaries will:

    - carry on their businesses in the ordinary course;

    - preserve intact their business organizations and relationships with
      customers, suppliers and others having business dealings with them, keep
      available the services of their present officers and employees as a group
      (subject to prudent management of workforce needs and ongoing programs
      currently in force), maintain properties and assets in good repair, and
      maintain supplies and inventories in quantities consistent with past
      practice;

    - abide by certain customary restrictions on the conduct of their businesses
      regarding: (1) dividends, (2) stock splits and issuances of CTG Resources
      shares, (3) redemptions of CTG Resources shares, (4) substantial equity
      and asset acquisitions and dispositions, (5) capital expenditures, (6)
      indebtedness, (7) employee benefit plans and other employment
      arrangements, (8) tax and accounting matters, (9) discharge of
      liabilities, (10) amending, terminating and renewing material contracts
      and (11) insurance;

    - not engage in any activities that would cause a change in their status
      under the Public Utility Holding Company Act;

    - use reasonable efforts to maintain in effect all existing governmental
      permits pursuant to which they operate; and

    - ensure that the merger will not result in the grant of any rights to any
      person under any material agreement (other than the employment agreements
      disclosed in the schedules to the merger agreement) or in the exercise of
      any rights under the CTG Resources rights agreement or otherwise.

    NO SOLICITATION OF ALTERNATIVE PROPOSALS.  CTG Resources also agreed to
certain restrictions concerning "ALTERNATIVE PROPOSALS," which are defined in
the merger agreement as mergers, consolidations or similar transactions between
third parties and CTG Resources or its subsidiaries, or any third-party
proposals or offers to acquire in any manner, directly or indirectly, a
substantial equity

                                       63
<PAGE>
interest in or a substantial portion of the assets of CTG Resources or any of
its subsidiaries. Specifically, CTG Resources agreed that:

    - neither it nor CTG Resources's subsidiaries will encourage, initiate,
      solicit or take any other action to facilitate knowingly any inquiries,
      proposals or offers that constitute or may reasonably be expected to lead
      to an Alternative Proposal from any person;

    - neither it nor CTG Resources's subsidiaries will engage in any discussion
      or negotiations concerning, or provide any nonpublic information or data
      to make or implement, an Alternative Proposal;

    - it will immediately cease and cause to be terminated any existing
      solicitation, initiation, encouragement, activity, discussions or
      negotiations with any parties conducted with a view of formulating an
      Alternative Proposal; and

    - it will notify Energy East of any of these inquiries, offers or proposals
      within one business day of their receipt, it will keep Energy East
      informed of their status, and it will give Energy East 48 hours' advance
      notice of its intent to enter into any agreement or to commence providing
      information to any person making the inquiry, offer or proposal.

    Nonetheless, CTG Resources may take the following steps:

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

     - the CTG Resources board of directors concludes that the third party has
       made an Alternative Proposal that is financially superior to the merger
       and has demonstrated that any necessary financing has been obtained or,
       in the reasonable judgment of CTG Resources's financial advisor, is
       obtainable, and the CTG Resources board of directors concludes in good
       faith, after consultation with its financial advisor and based upon the
       advice of outside counsel and other relevant matters, that failure to
       take the above-mentioned steps would likely result in a breach of its
       fiduciary duties under applicable law; and

     - before CTG Resources provides information to, or enters into discussions
       or negotiations with, the third party, CTG Resources (1) promptly
       notifies Energy East that it intends to furnish information to, or
       intends to enter into discussions with, that third party; (2) provides
       Energy East a reasonable opportunity to respond to the Alternative
       Proposal; and (3) receives from the third party an executed
       confidentiality agreement;

     - CTG Resources may comply with Rule 14e-2 under the Securities Exchange
       Act of 1934 regulating tender or exchange offers; or

     - CTG Resources may accept an Alternative Proposal from a third party,
       provided that it first terminates the merger agreement with Energy East.

ADDITIONAL AGREEMENTS

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

    ACCESS TO INFORMATION.  Upon reasonable notice and during normal business
hours until the effective time of the merger, each party will provide the other
side reasonable access to all of its properties, books, contracts, commitments
and records. In addition, the parties will provide to each other (1) access to
all reports, schedules and other documents that they or their subsidiaries filed
or received under federal or state securities laws or filed with or sent to the
SEC, the Federal Energy

                                       64
<PAGE>
Regulatory Commission, the Antitrust Division of the Department of Justice, the
Federal Trade Commission, or any other U.S. federal or state regulatory agency
or commission, and (2) access to all information concerning themselves, their
subsidiaries, directors, officers and shareholders, and other matters that the
other party may reasonably request in connection with any filings, applications,
or approvals required under the merger agreement. Each party will hold in strict
confidence all information furnished to it in connection with the merger.

    REGULATORY MATTERS.  CTG Resources and Energy East will cooperate with each
other and use their best efforts to prepare and file promptly all necessary
documentation, to effect all necessary applications, notices, petitions, filings
and other documents, and to use all commercially reasonable efforts to obtain
required governmental consents by December 29, 2000.

    SHAREHOLDER APPROVAL.  CTG Resources will take all steps necessary to hold
the special meeting to obtain the necessary two-thirds vote to approve the
merger. Subject to their fiduciary duties, the CTG Resources board of directors
will recommend to the shareholders the approval of the merger agreement.

    INDEMNIFICATION OF DIRECTORS AND OFFICERS.  To the extent these individuals
are not otherwise indemnified, Energy East and the surviving company have agreed
to indemnify, after the effective time of the merger, each individual who has
ever been an officer, director or employee of CTG Resources or any of its
subsidiaries. This indemnification will cover all losses, expenses (including
reasonable attorneys' fees and expenses), claims, damages, liabilities or
amounts paid in settlement (if Energy East provided written consent to the
settlement) arising out of actions or omissions occurring at or before the
effective time of the merger that are at least in part (1) based on the fact
that such individual served as a director, officer or employee of CTG Resources
or one of its subsidiaries or (2) based on the transactions contemplated by the
merger agreement. Energy East will advance to the indemnified party, upon
request, reimbursement of documented expenses reasonably incurred. Independent
counsel mutually acceptable to Energy East and the indemnified individual will
make all necessary determinations to decide whether an indemnified individual's
conduct complies with the standards for indemnification established by
Connecticut law and the governing certificate of incorporation and by-laws.
These rights to indemnification will continue for at least six years after the
effective time of the merger.

    INSURANCE.  For six years after the effective time of the merger, Energy
East will either (1) maintain liability insurance policies for the benefit of
those directors and officers of CTG Resources and its subsidiaries who are
currently covered or (2) provide tail coverage for those directors and officers.
In either case, the terms of the coverage will be at least as favorable as the
terms of the current insurance coverage. Energy East will not, however, be
required to expend in any year more than 200% of the annual aggregate premiums
that CTG Resources currently pays.

    PUBLIC ANNOUNCEMENTS.  Subject to their legal obligations to disclose
information, CTG Resources and Energy East 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 without the consent of the other
party (the consent cannot be withheld unreasonably).

    EMPLOYEE AGREEMENTS.  Except as provided below, Energy East and its
subsidiaries will honor, without modification, all existing contracts,
agreements and commitments of CTG Resources that were entered into before June
29, 1999, and apply to current or former employees and directors of CTG
Resources.

                                       65
<PAGE>
    Energy East and CTG Resources intend to continue their present strategy of
achieving workforce reductions through attrition, instead of through involuntary
layoffs. If any reductions in workforce become necessary in the future, they
will be made on a fair and equitable basis, giving consideration to previous
work history, job experience, qualifications and business needs without regard
to whether employment before the merger was with CTG Resources or its
subsidiaries or Energy East or its subsidiaries. Any employees whose employment
is terminated or whose jobs are eliminated will have a right to participate, on
a fair and equitable basis, in the job opportunity and employment placement
programs offered by Energy East, the surviving company or any of its
subsidiaries. Any workforce reductions carried out after the effective time of
the merger will be done in accordance with all applicable collective bargaining
agreements and all relevant laws and regulations, including the Worker
Adjustment and Retraining Notification Act and any similar U.S. federal, state
or local law.

    EMPLOYEE BENEFIT PLANS.  For at least 18 months after the merger becomes
effective, Energy East must provide all employees of CTG Resources and its
subsidiaries who are covered by benefit plans and who are not covered by
collective bargaining agreements with benefits that are at least as favorable as
the benefits they receive immediately before the merger. Further, all employees
of CTG Resources and its subsidiaries who are covered by benefit plans and who
are not covered by collective bargaining agreements will receive credit, for all
purposes other than benefit accrual, for their service with CTG Resources or any
of its subsidiaries. Finally, after the merger becomes effective, those
employees who are participants in the Connecticut Natural Gas's officers'
retirement plan immediately before the merger will continue to accrue benefits
under terms at least as favorable as the terms currently in effect.

    CTG RESOURCES'S STOCK PLANS.  With respect to CTG Resources's stock plans,
both companies will take all necessary actions to:

    - provide for the issuance or purchase in the open market of Energy East
      shares rather than CTG Resources shares under those plans, and to make
      other changes in the CTG Resources stock plans to reflect the merger
      agreement;

    - obtain CTG Resources shareholder approval with respect to the CTG
      Resources stock plans to the extent this approval is required to comply
      with the Exchange Act (and the rules and regulations promulgated
      thereunder), the Internal Revenue Code or other applicable law;

    - reserve for issuance under the CTG Resources stock plans or otherwise
      provide a sufficient number of Energy East shares for delivery upon
      payment of benefits, grant of awards, or exercise of options under these
      plans;

    - file all required registration statements and amendments that are
      necessary to register the Energy East shares that are subject to the CTG
      Resources stock plans; and

    - cancel each outstanding option to purchase CTG Resources shares, whether
      or not the option has vested, in exchange for a cash payment equal to (1)
      the excess of $41.00 over the exercise price of the option, multiplied by
      (2) the number of shares covered by the option, less applicable tax and
      withholding.

    In addition, restricted shares granted under the Connecticut Natural Gas's
executive restricted stock plan will become fully vested, and owners of these
shares will have the opportunity, along with other shareholders, to receive
either cash or Energy East shares in exchange for their shares. Employees who
are participants in CTG Resources's annual incentive plan but who have not
entered into an employment agreement with CTG Resources, the benefits of which
are triggered by a change of control, will be entitled to participate on a pro
rata basis in an Energy East annual incentive plan for the remainder of the
fiscal year of Energy East in which the merger occurs.

                                       66
<PAGE>
    EXPENSES.  Except for those expenses incurred in connection with the
printing and filing of this proxy statement/prospectus (which expenses are being
shared equally by CTG Resources and Energy East) and except as described under
"-- Termination, Amendment and Waiver," both parties will pay their own costs
and expenses incurred in connection with the merger.

    FURTHER ASSURANCES.  Each party and its subsidiaries will execute all
additional documents and instruments and take all other actions that the other
party may reasonably request in order to complete the merger.

    CORPORATE OFFICES.  After the effective time of the merger, the corporate
headquarters of the surviving company will be located in Hartford, Connecticut.
At and subsequent to the effective time of the merger, the corporate
headquarters of XENERGY Enterprises, a wholly owned subsidiary of Energy East,
will also be located in Connecticut.

    COMMUNITY INVOLVEMENT.  After the effective time of the merger, Energy East
or the surviving company will make annual charitable contributions of at least
$500,000 to the communities that the surviving company serves, and otherwise
maintain a substantial level of involvement in community activities in the State
of Connecticut that is at least as high as the level of community development
and related activities currently carried on by CTG Resources.

    ADVISORY BOARD.  The surviving company will set up an advisory board
comprised of the individuals who were directors of CTG Resources immediately
before the effective time of the merger. The advisory board will meet at least
quarterly and will provide advice to the surviving company board of directors as
requested. The members of the advisory board, who will serve at the discretion
of the surviving company, will receive remuneration for their services
equivalent to that currently provided to non-officer directors of CTG Resources.

CONDITIONS

    MUTUAL CONDITIONS.  The obligations of CTG Resources, Energy East and Oak
Merger Co. to complete the merger are subject to satisfaction of the following
conditions:

    - CTG Resources shareholders must have approved the merger agreement and the
      merger.

    - No U.S. federal or state court may have issued a temporary restraining
      order or injunction that prevents completion of the merger, and there is
      no U.S. federal or state law or regulation prohibiting the merger.

    - The SEC must have declared effective the registration statement pertaining
      to the Energy East shares to be issued in connection with the merger.

    - The New York Stock Exchange must have approved for listing the Energy East
      shares to be issued in the merger.

    - CTG Resources and Energy East must have obtained the requisite
      governmental approvals by the effective time of the merger and all
      applicable waiting periods must have expired. In addition, no governmental
      authority may have imposed terms or conditions that would have a material
      adverse effect on either CTG Resources or Energy East. The parties have
      agreed that, although a requirement that Energy East become a registered
      holding company under the Public Utility Holding Company Act would not
      constitute a term or condition having a material adverse effect on either
      CTG Resources or Energy East, a requirement that Energy East divest its
      ownership of NYSEG would constitute a term or condition having a material
      adverse effect.

    CONDITIONS TO OBLIGATIONS OF ENERGY EAST.  The obligations of Energy East to
complete the merger are contingent on the satisfaction of, or waiver by Energy
East of, the following conditions:

                                       67

      and covenants required by the merger agreement.

    - The representations and warranties of CTG Resources contained in the
      merger agreement must be true and correct on the date of the merger
      agreement and on the closing date of the merger (except for
      representations and warranties made as of a specified date, the accuracy
      of which will be determined as of the specified date), unless any
      inaccuracy of the representations and warranties would not reasonably be
      expected to have a material adverse effect on CTG Resources.

    - CTG Resources must have provided Energy East with a certificate, dated the
      closing date of the merger, signed by CTG Resources's chief financial
      officer regarding satisfaction of the two preceding conditions.

    - CTG Resources has not suffered a material adverse effect, and there is no
      fact or circumstance, unless it was disclosed in the schedules to the
      merger agreement or in CTG Resources's public documents prior to June 29,
      1999, that is reasonably likely to have a material adverse effect on CTG
      Resources.

    - CTG Resources must have obtained the requisite third-party consents,
      unless the failure to obtain those consents would not have a material
      adverse effect on CTG Resources.

    - Each affiliate of CTG Resources must have signed an agreement stating that
      the affiliate will not sell the Energy East shares that it receives in the
      merger, except in accordance with Rule 145 promulgated under the
      Securities Act.

    - Attorneys for Energy East must have furnished to Energy East an opinion to
      the effect that the merger will be treated as a reorganization within the
      meaning of Section 368(a) of the Internal Revenue Code.

    CONDITIONS TO OBLIGATIONS OF CTG RESOURCES.  The obligations of CTG
Resources to complete the merger agreement and the merger are contingent on the
satisfaction of, or waiver by CTG Resources of, the following conditions:

    - Energy East must have performed in all material respects the agreements
      and covenants required by the merger agreement.

    - The representations and warranties of Energy East contained in the merger
      agreement must be true and correct on the date of the merger agreement and
      on the closing date of the merger (except for representations and
      warranties made as of a specified date, the accuracy of which will be
      determined as of the specified date), unless any inaccuracy of the
      representations and warranties would not reasonably be expected to have a
      material adverse effect on Energy East.

    - Energy East must have provided CTG Resources with a certificate, dated the
      closing date of the merger, signed by Energy East's executive vice
      president and general counsel regarding satisfaction of the two preceding
      conditions.

    - Energy East has not suffered a material adverse effect, and there is no
      fact or circumstance, unless it was disclosed in Energy East's public
      documents prior to June 29, 1999, that is reasonably likely to have a
      material adverse effect on Energy East.

    - Energy East must have obtained the requisite third-party consents, unless
      the failure to obtain those consents would not have a material adverse
      effect on Energy East.

    - Attorneys for CTG Resources must have furnished to CTG Resources an
      opinion to the effect that the merger will be treated as a reorganization
      within the meaning of Section 368(a) of the Internal Revenue Code.

                                       68
<PAGE>
TERMINATION, AMENDMENT AND WAIVER

    TERMINATION.  The merger agreement may be terminated at any time before the
effective time of the merger, even after the CTG Resources shareholders have
already approved it (unless otherwise noted below):

    - by mutual written consent of the CTG Resources board of directors and the
      Energy East board of directors;

    - by either CTG Resources or Energy East if they have not completed the
      merger by June 29, 2000 (or December 29, 2000, if the only barrier to the
      closing of the merger is the inability to obtain the requisite
      governmental approvals), so long as the delay has not been caused by a
      failure of the party seeking termination to fulfill its obligations under
      the merger agreement;

    - by either CTG Resources or Energy East if any state or federal law
      prohibits the merger (this determination must be supported by the written
      opinion of outside counsel) or if any state or federal court of competent
      jurisdiction issues a final and nonappealable decision that permanently
      enjoins the merger;

    - by CTG Resources, before its shareholders approve the merger agreement, if
      CTG Resources is not in breach of the merger agreement and, as a result of
      an Alternative Proposal, the CTG Resources board of directors determines
      in good faith that

       - the Alternative Proposal is financially superior to the merger and the
         third party making the Alternative Proposal has obtained or, in the
         reasonable judgment of CTG Resources's financial advisor, can obtain
         the necessary financing; and

       - after consultation with its financial advisor and based upon the advice
         of outside counsel and other relevant matters, that failure to do so
         would likely result in a breach of its fiduciary duties under
         applicable law; provided that before CTG Resources may terminate the
         merger agreement:

           (1) CTG Resources must give Energy East five days' prior notice of
               its intent to accept the alternative acquisition proposal; and

           (2) CTG Resources and its financial and legal advisors must give
               Energy East a reasonable opportunity during this five-day period
               to make any adjustments in the terms of the merger agreement that
               would allow CTG Resources to proceed with the merger, and must
               negotiate with Energy East towards adjusting the merger agreement
               so as to enable the merger to proceed;

    - by CTG Resources if:

       - Energy East has breached any of its representations, warranties or
         covenants in the merger agreement, the breach would be reasonably
         likely to result in a material adverse effect on Energy East, and
         Energy East does not cure the breach within 20 days of receiving
         written notice of the breach from CTG Resources; or

    - by Energy East if:

       - CTG Resources has breached any of its representations, warranties or
         covenants in the merger agreement, the breach would be reasonably
         likely to result in a material adverse effect on CTG Resources, and CTG
         Resources does not cure the breach within 20 days of receiving written
         notice of the breach from Energy East; or

       - the CTG Resources board of directors or any committee thereof (1)
         withdraws or modifies in any manner adverse to Energy East its approval
         or recommendation of the merger agreement or the merger, (2) fails to
         reaffirm its approval or recommendation upon Energy

                                       69
<PAGE>
         East's request within two days of that request, (3) approves or
         recommends any acquisition of CTG Resources or a material portion of
         its assets or any tender offer for the shares of capital stock of CTG
         Resources by someone other than Energy East or any of its affiliates,
         or (4) resolves to take any of these actions.

    EFFECT OF TERMINATION.  CTG Resources and Energy East have agreed that, if
either of them terminates the merger agreement for any reason outlined above,
the merger agreement -- except for the provisions concerning expenses,
termination fees, confidentiality of information subject to the terms of a
confidentiality agreement, waiver of a jury trial and certain damages and
enforcement of the agreement -- will become void and have no effect, without any
liability on the part of any party, their officers or their directors.
Nonetheless, if either party materially breaches any provision of the merger
agreement and the other party consequently terminates the agreement, then the
breaching party will have to give the other party an amount in cash equal to all
documented out-of-pocket expenses and fees incurred by the other party not in
excess of $4 million. However, if the breach is willful, the merger agreement
does not limit the amount of damages that the nonbreaching party may seek.

    CTG Resources must pay Energy East a termination fee of $14 million plus
fees and expenses up to $4 million if the merger agreement is terminated for any
of the following reasons:

    - the CTG Resources board of directors decides to pursue an Alternative
      Proposal;

    - CTG Resources shareholders fail to approve the merger by June 29, 2000,
      but only if there was an Alternative Proposal outstanding at the time of
      the special meeting and if, within two years of such termination, CTG
      Resources enters into a definitive agreement to complete or actually does
      complete an Alternative Proposal; or

    - the CTG Resources board of directors withdraws, modifies, or fails to
      affirm its approval or recommendation to CTG Resources shareholders, but
      only if there was an Alternative Proposal outstanding at the time of the
      termination and if, within two years of such termination, CTG Resources
      enters into a definitive agreement to complete or actually does complete
      an Alternative Proposal.

    AMENDMENT.  The parties' boards of directors may amend the merger agreement
at any time before the effective time of the merger, whether or not the CTG
Resources shareholders have already approved the agreement. After CTG Resources
shareholder approval, however, no such amendment can (1) alter the merger
consideration or the mechanics of the share exchange or (2) change any of the
terms and conditions of the merger agreement if any of the changes would
materially adversely affect the rights of CTG Resources shareholders (except for
changes that could otherwise be adopted by the CTG Resources board of directors
without the further approval of the CTG Resources shareholders).

    WAIVER.  At any time before the effective time of the merger, to the extent
permitted by applicable law, the parties may extend the time for the performance
of any of the obligations or other acts required by the merger agreement, waive
any inaccuracies in the representations and warranties contained in the merger
agreement, and waive compliance with any of the agreements or conditions
contained in the merger agreement. Any agreement on the part of a party to any
such extension or waiver shall be valid if set forth in an instrument in writing
signed on behalf of such party.

                              UNAUDITED PRO FORMA
                    COMBINED CONDENSED FINANCIAL STATEMENTS

    The following unaudited pro forma combined condensed financial statements
have been prepared to reflect the sales of Energy East's generation assets, the
CTG Resources merger, the Connecticut Energy merger, the sale of CMP Group's
generation assets and the CMP Group merger. The unaudited pro forma combined
condensed financial statements are organized as follows: first, statements are
presented to reflect the sales of Energy East's generation assets and the CTG
Resources merger; second, statements are presented to reflect the sales of
Energy East's generation assets, the CTG Resources merger and the Connecticut
Energy merger; and finally, statements are presented to reflect the sales of
Energy East's generation assets, the CTG Resources merger, the Connecticut
Energy merger, the sale of CMP Group's generation assets and the CMP Group
merger.

    All three mergers will be accounted for as purchases. The nonutility assets
and liabilities of CTG Resources, Connecticut Energy and CMP Group will be
recorded in Energy East's consolidated financial statements at their estimated
fair values at the respective closing dates. The assets and liabilities of the
regulated utilities will not be revalued. See "The Merger -- Accounting
Treatment."

    The unaudited pro forma combined condensed financial statements reflect
preliminary purchase accounting adjustments in compliance with generally
accepted accounting principles. Estimates relating to the fair value of some
assets, liabilities and other events have been made as more fully described in
the notes to the financial statements. Actual adjustments will be made on the
basis of actual assets, liabilities and other items as of the closing dates of
the CTG Resources merger, the Connecticut Energy merger and the CMP Group merger
on the basis of appraisals and evaluations. Therefore, actual amounts may differ
from those reflected below.

    The unaudited pro forma combined condensed balance sheets assume that the
mergers and the sale of Energy East's nuclear generation assets occurred on June
30, 1999; the actual balance sheet data for June 30, 1999 already include the
sale of Energy East's coal-fired generation assets and the sale of CMP Group's
steam and hydro generation assets, which occurred prior to that date. The
unaudited pro forma combined condensed statements of income for the six months
ended June 30, 1999 and the unaudited pro forma combined condensed statements of
income for the year ended December 31, 1998 assume that each of the mergers and
all of the sales of the generation assets were completed on January 1, 1998. For
purposes of pro forma presentation for the year ended December 31, 1998, CTG
Resources's and Connecticut Energy's consolidated statements of income for their
September 30, 1998 fiscal year are used.

    The following pro forma financial statements should be read in conjunction
with the consolidated historical financial statements and the related notes of
Energy East, CTG Resources, Connecticut Energy and CMP Group, which are
incorporated by reference. See "Where You Can Find More Information."

    The following pro forma financial statements are for illustrative purposes
only. They are not necessarily indicative of the financial position or operating
results that would have occurred had the sales and the mergers been completed on
January 1, 1998 or June 30, 1999, as assumed above; nor is the information
necessarily indicative of future financial position or operating results.

    Fifty-five percent of the CTG Resources shares outstanding immediately prior
to the effective time of the CTG Resources merger will be converted into the
right to receive $41.00 per share in cash, and 45% will be converted into, on a
per share basis, a number of Energy East shares valued at $41.00, subject to
restrictions on the maximum and minimum number of Energy East shares to be
issued. The number of Energy East shares to be exchanged for each CTG Resources
share will be between 1.3609 and 1.7320, based on the closing prices of Energy
East shares on the New York Stock Exchange during

                                       72
<PAGE>
the 20-trading-day period ending two trading days before the effective time of
the CTG Resources merger.

    Half of the Connecticut Energy shares outstanding immediately prior to the
effective time of the merger will be converted into the right to receive $42.00
per share in cash, and half will be converted into, on a per share basis, a
number of Energy East shares valued at $42.00, subject to restrictions on the
maximum and minimum number of Energy East shares to be issued. The number of
Energy East shares to be exchanged for each Connecticut Energy share will be
between 1.43 and 1.82, based on the closing prices of Energy East shares on the
New York Stock Exchange during the 20-trading-day period ending two trading days
before the effective time of the merger.

    Each CMP Group share outstanding immediately prior to the effective time of
the CMP Group merger will be converted into the right to receive $29.50 in cash.

    Energy East expects to issue long-term debt, the proceeds of which, along
with the proceeds from the sales of its generation assets and internally
generated funds, will be used to help fund the cash portion of the consideration
in the CTG Resources merger, the Connecticut Energy merger and the CMP Group
merger, and to help fund Energy East's ongoing share repurchase program. The
unaudited pro forma financial statements, for illustrative purposes, reflect the
issuance of the long-term debt and the use of all of the proceeds to help fund
the consideration paid to CMP Group shareholders.

  NOTES TO UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS GIVING
             EFFECT TO THE SALES OF ENERGY EAST'S GENERATION ASSETS
                          AND THE CTG RESOURCES MERGER

NOTE 1. UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS.

    The unaudited pro forma combined condensed balance sheet as of June 30,
1999, has been adjusted to give effect to the sale of Energy East's 18% interest
in the Nine Mile Point nuclear generating unit No. 2 to AmerGen Energy Company,
which it expects to complete early next year, and the CTG Resources merger. The
actual balance sheet for June 30, 1999, includes the sales of Energy East's
coal-fired generation assets that were completed this year prior to June 30,
1999. The unaudited pro forma combined condensed statements of income for the
six months ended June 30, 1999, and the twelve months ended December 31, 1998,
give effect to all of the sales of Energy East's generation assets and the CTG
Resources merger as if those events occurred on January 1, 1998.

    The generation adjustments on the pro forma balance sheet represent the
amount of utility plant and fuel sold. Cash received, regulatory assets affected
and liabilities incurred related to the sale, such as income taxes and estimated
transaction costs, are also reflected in the adjustments.

    The generation adjustments on the pro forma income statements, which were
based upon certain assumptions, do not reflect nonrecurring charges and credits
related to the sale of the plants. Operating expense and maintenance expense
include all amounts directly related to the operation and maintenance of
generation plus corporate administrative and general costs allocated based on
net revenues.

NOTE 2. ACCOUNTING METHOD.

    The CTG Resources merger will be accounted for as an acquisition of CTG
Resources by Energy East under the purchase method of accounting in accordance
with generally accepted accounting principles. A portion of the purchase price
will be allocated to nonutility assets and liabilities of CTG Resources based on
their estimated fair market values at the date of acquisition. As a regulated
utility, the assets and liabilities of Connecticut Natural Gas will not be
revalued. The difference between the purchase price, representing fair value,
and the recorded amounts will be shown as goodwill on the balance sheet.

NOTE 3. MERGER.

    The historical consolidated financial statements of Energy East and CTG
Resources for the years ended December 31, 1998, and September 30, 1998, and as
of and for the six months ended June 30, 1999, have been adjusted to give effect
to the CTG Resources merger.

NOTE 4. EARNINGS PER SHARE AND AVERAGE SHARES OUTSTANDING.

    The pro forma earnings per share and number of average shares outstanding
have been restated to reflect Energy East's two-for-one common stock split,
effective April 1, 1999, and the average number of shares that would have been
outstanding if the merger occurred at the beginning of the periods presented
assuming a conversion of 45% of the CTG Resources shares into 1.57 Energy East
shares per CTG Resources share. The following table presents the range of shares
that could be issued based on various potential conversion ratios under the
merger agreement:

<PAGE>
NOTE 5. CASH CONSIDERATION.

    Reflects the cash consideration paid to CTG Resources shareholders based on
a purchase price per share of $41.00 for 55% of the shares outstanding.

NOTE 6. OTHER ASSETS.

    Reflects the recognition of an other asset and reduction of goodwill for the
estimated difference between CTG Resources's pension and other postretirement
benefit obligations and the fair value of the respective plan assets.

NOTE 7. GOODWILL.

    Reflects the recognition of an amount of goodwill equal to the excess of the
estimated purchase price of $355 million over the estimated net fair value of
the assets and liabilities of CTG Resources acquired of $134 million, plus
estimated transaction costs of $3.5 million related to the merger, reduced by
the estimated difference between CTG Resources's pension and other
postretirement obligations and the fair value of the respective plan assets.

NOTE 8. MERGER-RELATED COSTS.

    Energy East and CTG Resources will incur direct expenses related to the
merger, including accounting and consulting fees. The pro forma adjustments
include an estimate for Energy East's merger-related costs of $3.5 million,
which is included in goodwill. CTG Resources expects to incur approximately $5.5
million of merger-related costs, which it will expense as incurred. The actual
amount of merger-related costs may differ from the amounts reflected in the
unaudited pro forma combined condensed financial statements.

NOTE 9. COMMON STOCK.

    Reflects the Energy East shares to be issued to CTG Resources shareholders
in exchange for 45% of their CTG Resources shares, assuming a conversion ratio
of 1.57 Energy East shares per CTG Resources share, and the purchase of 55% of
their CTG Resources shares for cash.

NOTE 10. INCOME TAXES.

    Income taxes on the pro forma income statements have been based on the
statutory rate and adjusted for goodwill, which is not tax deductible.

NOTE 11. AMORTIZATION OF GOODWILL.

    Represents the amortization of goodwill, for financial accounting purposes,
over a 40-year period. The goodwill is not amortizable for tax purposes.

NOTE 12. ENERGY EAST SHARES ISSUED.

    Reflects the number of Energy East shares to be issued in the merger
assuming a conversion of 45% of the CTG Resources shares into 1.57 Energy East
shares per CTG Resources share.

NOTE 13. NET INCOME FOR THREE MONTHS ENDED DECEMBER 31, 1998.

    CTG Resources's revenues for the three months ended December 31, 1998, were
$81.7 million, and net income for the same period was $5.7 million or 65 cents
per share, diluted.

      NOTES TO UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS
         GIVING EFFECT TO THE SALES OF ENERGY EAST'S GENERATION ASSETS,
           THE CTG RESOURCES MERGER AND THE CONNECTICUT ENERGY MERGER

NOTE 1. UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS.

    The unaudited pro forma combined condensed balance sheet as of June 30, 1999
has been adjusted to give effect to the disposition of Energy East's 18%
interest in the Nine Mile Point Nuclear generating unit No. 2 to AmerGen Energy
Company, which it expects to complete early next year, the CTG Resources merger
and the Connecticut Energy merger. The actual balance sheet for June 30, 1999,
includes the sales of Energy East's coal-fired generation assets that were
completed this year prior to June 30, 1999. The unaudited pro forma combined
condensed statements of income for the six months ended June 30, 1999, and the
twelve months ended December 31, 1998, give effect to all of the sales of Energy
East's generation assets, the CTG Resources merger and the Connecticut Energy
merger as if these events occurred on January 1, 1998.

NOTE 2. ACCOUNTING METHOD.

    The Connecticut Energy merger will be accounted for as an acquisition of
Connecticut Energy by Energy East under the purchase method of accounting in
accordance with generally accepted accounting principles. A portion of the
purchase price will be allocated to nonutility assets and liabilities of
Connecticut Energy based on their estimated fair market values at the date of
acquisition. As a regulated utility, the assets and liabilities of The Southern
Connecticut Gas Company will not be revalued. The difference between the
purchase price, representing fair value, and the recorded amounts will be shown
as goodwill on the balance sheet.

NOTE 3. MERGER.

    The historical consolidated financial statements of Energy East, CTG
Resources and Connecticut Energy for the year ended December 31, 1998, and
September 30, 1998, and as of and for the six months ended June 30, 1999, have
been adjusted to give effect to the CTG Resources merger and the Connecticut
Energy merger.

NOTE 4. EARNINGS PER SHARE AND AVERAGE SHARES OUTSTANDING.

    The pro forma earnings per share and number of average shares outstanding
have been restated to reflect Energy East's two-for-one common stock split,
effective April 1, 1999, and the average number of shares that would have been
outstanding if the merger occurred at the beginning of the periods presented
assuming a conversion of half of the Connecticut Energy shares into 1.60 Energy
East shares per Connecticut Energy share. The following table presents the range
of shares that could be issued based on various potential conversion ratios
provided for by the merger agreement:

<TABLE>
<S>                                                              <C>        <C>        <C>
Conversion ratio...............................................       1.43       1.60       1.82
Number of shares (thousands)...................................      7,427      8,310      9,453
</TABLE>

NOTE 5. CASH CONSIDERATION.

    Reflects the cash consideration paid to Connecticut Energy shareholders
based on a purchase price per share of $42.00 for half of the shares
outstanding.

                                       84
<PAGE>
NOTE 6. OTHER ASSETS.

    Reflects the recognition of an other asset and reduction of goodwill for the
estimated difference between Connecticut Energy's pension and other
postretirement benefit obligations and the fair value of the respective plan
assets.

NOTE 7. GOODWILL.

    Reflects the recognition of goodwill equal to the excess of the estimated
purchase price of $436.3 million over the estimated net fair value of the assets
and liabilities of Connecticut Energy acquired of $191.4 million, plus estimated
transaction costs of $4.5 million related to the merger, reduced by the
estimated difference between Connecticut Energy's pension and other
postretirement benefit obligations and the fair value of the respective plan
assets.

NOTE 8. MERGER-RELATED COSTS.

    Energy East and Connecticut Energy will incur direct expenses related to the
merger, including accounting and consulting fees. The pro forma adjustments
include an estimate for Energy East's merger-related costs of $4.5 million,
which is included in goodwill. Connecticut Energy expects to incur approximately
$6.9 million of merger-related costs, which it will expense as incurred. The
actual amount of merger-related costs may differ from the amounts reflected in
the unaudited pro forma combined condensed financial statements.

NOTE 9. INCOME TAXES.

    Income taxes on the pro forma income statements have been based on the
statutory rate and adjusted for goodwill, which is not tax deductible, and such
items as depreciation that are accounted for differently for tax purposes.

NOTE 10. COMMON STOCK.

    Reflects the Energy East shares issued to Connecticut Energy shareholders in
exchange for half of their Connecticut Energy shares, assuming a conversion
ratio of 1.60 Energy East shares per Connecticut Energy share, and the purchase
of half of their Connecticut Energy shares for cash.

NOTE 11. AMORTIZATION OF GOODWILL.

    Represents the amortization of goodwill, for financial accounting purposes,
over a 40-year period. The goodwill is not amortizable for tax purposes.

NOTE 12. ENERGY EAST SHARES ISSUED.

    Reflects the number of Energy East shares to be issued in the merger
assuming a conversion of half of the Connecticut Energy shares into 1.60 Energy
East shares per Connecticut Energy share.

NOTE 13. NET INCOME FOR THREE MONTHS ENDED DECEMBER 31, 1998.

    Connecticut Energy's revenues for the three months ended December 31, 1998,
were $61.6 million, and net income for the same period was $6.1 million or 59
cents per share, diluted.

      THE CTG RESOURCES MERGER, THE CONNECTICUT ENERGY MERGER, THE SALE OF
             CMP GROUP'S GENERATION ASSETS AND THE CMP GROUP MERGER

NOTE 1. UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS.

    The unaudited pro forma combined condensed balance sheet as of June 30,
1999, has been adjusted to give effect to the disposition of Energy East's 18%
interest in the Nine Mile Point nuclear generating unit No. 2 to AmerGen Energy
Company, which it expects to complete early next year, the CTG Resources merger,
the Connecticut Energy merger, the sale of CMP Group's generation assets and the
CMP Group merger. The actual balance sheet for June 30, 1999, includes the sales
of Energy East's coal-fired generation assets and the sale of CMP Group's steam
and hydro generation assets that were completed this year prior to June 30,
1999. The unaudited pro forma combined condensed statements of income for the
six months ended June 30, 1999, and the twelve months ended December 31, 1998,
give effect to all of the sales of Energy East's generation assets, the CTG
Resources merger, the Connecticut Energy merger, the sale of CMP Group's
generation assets and the CMP Group merger.

NOTE 2. ACCOUNTING METHOD.

    The CMP Group merger will be accounted for as an acquisition of CMP Group by
Energy East under the purchase method of accounting in accordance with generally
accepted accounting principles. A portion of the purchase price will be
allocated to nonutility assets and liabilities of CMP Group based on their
estimated fair market values at the date of acquisition. As a regulated utility,
the assets and liabilities of Central Maine Power Company will not be revalued.
The difference between the purchase price, representing fair value, and the
recorded amounts will be shown as goodwill on the balance sheet.

NOTE 3. MERGER.

    The historical consolidated financial statements of Energy East, Connecticut
Energy, and CMP Group for the 12 months ended December 31, 1998, and September
30, 1998, and as of and for the six months ended June 30, 1999, have been
adjusted to give effect to the Connecticut Energy merger and the CMP Group
merger.

purchase price of $29.50 per share for all of the CMP Group shares outstanding.

NOTE 5. NOTES PAYABLE.

    Reflects the issuance of $500 million principal amount of notes payable with
an assumed interest rate of 7.5%, the proceeds of which may be used to fund the
consideration paid to CMP Group shareholders.

NOTE 6. MERGER-RELATED COSTS.

    Energy East and CMP Group will incur direct expenses related to the merger,
including accounting and consulting fees. The pro forma adjustments include an
estimate for Energy East's merger-related costs of $6.5 million, which is
included in goodwill. CMP Group expects to incur approximately $7.5 million of
merger-related costs, which it will expense as incurred. The actual

                                       90
<PAGE>
amount of merger-related costs may differ from the amounts reflected in the
unaudited pro forma combined condensed financial statements.

NOTE 7. GOODWILL.

    Reflects the recognition of an amount of goodwill equal to the excess of the
estimated purchase price of $957 million over the estimated net fair value of
the assets and liabilities of CMP Group acquired of $541.5 million, plus
estimated transaction costs of $6.5 million related to the merger, increased by
the estimated difference between CMP Group's pension and other postretirement
benefit obligations and the fair value of the respective plan assets.

NOTE 8. INCOME TAXES.

    Income taxes on the pro forma financial statements have been based on the
statutory rate and adjusted for goodwill, which is not tax deductible.

NOTE 9. AMORTIZATION OF GOODWILL.

    Represents the amortization of goodwill, for financial accounting purposes,
over a 40-year period. The goodwill is not amortizable for tax purposes.

secretary of CTG Resources at CTG Resources's principal office in Hartford,
Connecticut no later than August 19, 1999 to be included in CTG Resources's
proxy, notice of meeting and proxy statement relating to that meeting. Any
shareholder intending to propose any matter at the CTG Resources 2000 annual
meeting of shareholders but not intending CTG Resources to include the matter in
its proxy, notice of meeting and proxy statement relating to that meeting must
notify CTG Resources by December 15, 1999 of that intention. If CTG Resources
does not receive the notice by that date, the notice will be considered
untimely. CTG Resources's proxy for its 2000 annual meeting of shareholders will

by and among CTG Resources, Inc., a Connecticut corporation (the "Company"),

a Connecticut corporation and a wholly owned subsidiary of Parent ("Merger
Sub").

    WHEREAS, the Company and Parent have determined to engage in a business
combination transaction on the terms stated herein;

    WHEREAS, the respective Boards of Directors of the Company, Parent and
Merger Sub have approved and deemed it advisable and in the best interests of
their respective shareholders to consummate the transactions contemplated herein
under which the businesses of the Company and Parent would be combined by means
of the merger of the Company with and into Merger Sub; and

    WHEREAS, it is intended that the Merger (as defined below) shall constitute
a "reorganization" within the meaning of Section 368(a) of the Internal Revenue
Code of 1986, as amended (the "Code") and that this Agreement shall constitute a
plan of reorganization;

    NOW THEREFORE, in consideration of the premises and the representations,
warranties, covenants and agreements contained herein, the parties hereto,
intending to be legally bound hereby, agree as follows:

                                   ARTICLE I
                                   THE MERGER

    Section 1.1  THE MERGER.  Upon the terms and subject to the conditions of
this Agreement:

    At the Effective Time (as defined in Section 1.3), the Company shall be
merged with and into Merger Sub (the "Merger") in accordance with the laws of
the State of Connecticut. Merger Sub shall be the surviving corporation in the
Merger and shall continue its corporate existence under the laws of the State of
Connecticut. The effects and the consequences of the Merger shall be as set
forth in Section 1.2. Throughout this Agreement, the term "Merger Sub" shall
refer to Merger Sub prior to the Merger and the term "Surviving Corporation"
shall refer to Merger Sub in its capacity as the surviving corporation in the
Merger.

    Section 1.2  EFFECTS OF THE MERGER.  At the Effective Time, (i) the
certificate of incorporation of Merger Sub, as in effect immediately prior to
the Effective Time, shall be the certificate of incorporation of the Surviving
Corporation until thereafter amended as provided by law and such certificate of
incorporation, except that the name of the Surviving Corporation shall be "CTG
Resources, Inc.," and (ii) the by-laws of Merger Sub, as in effect immediately
prior to the Effective Time, shall be the by-laws of the Surviving Corporation
until thereafter amended as provided by law, the certificate of incorporation of
the Surviving Corporation and such by-laws. Subject to the foregoing, the
additional effects of the Merger shall be as provided in Section 33-820 of the
Connecticut Business Corporation Act (the "CBCA").

    Section 1.3  EFFECTIVE TIME OF THE MERGER.  On the Closing Date (as defined
in Section 3.1), with respect to the Merger, a certificate of merger complying
with Section 33-819 of the CBCA (the "Certificate of Merger") shall be delivered
to the Secretary of the State of Connecticut for filing. The

                                      A-1
<PAGE>
Merger shall become effective upon the filing of the Certificate of Merger, or
at such later date and time as may be set forth in the Certificate of Merger
(the "Effective Time").

    Section 1.4  DIRECTORS.  The directors of Merger Sub immediately prior to
the Effective Time and Mr. Arthur C. Marquardt shall be the directors of the
Surviving Corporation and shall hold office from the Effective Time until their
respective successors are duly elected or appointed and qualified in the manner
provided in the certificate of incorporation and by-laws of the Surviving
Corporation, or as otherwise provided by the CBCA.

    Section 1.5  OFFICERS.  Commencing at the Effective Time, and continuing
until his successor is duly elected or appointed and qualified in the manner
provided in the by-laws of the Surviving Corporation, Mr. Marquardt shall be
President and Chief Executive Officer of the Surviving Corporation and shall
hold other positions in other subsidiary corporations of Parent as specified in
his Employment Agreement (as defined in Section 6.3 hereof) subject to the terms
and conditions therein contained. The officers of Merger Sub immediately prior
to the Effective Time shall be the initial officers of the Surviving Corporation
(except that Mr. Marquardt shall be the President and Chief Executive Officer of
the Surviving Corporation) and shall hold office from the Effective Time until
their respective successors are duly elected or appointed and qualified in the
manner provided in the certificate of incorporation and by-laws of the Surviving
Corporation, or as otherwise provided by the CBCA.

                                   ARTICLE II
                              TREATMENT OF SHARES

    Section 2.1  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 Merger Sub:

        (a)  SHARES OF MERGER SUB STOCK.  Each share of common stock, without
par value, of Merger Sub (the "Merger Sub Common Stock") that is issued and
outstanding immediately prior to the Effective Time shall remain outstanding
unchanged by reason of the Merger as 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, without par value, of the Company, together with each associated
preferred share purchase right (a "Company Right") under the Rights Agreement,
dated as of December 1, 1998 (the "Company Rights Agreement"), between the
Company and ChaseMellon Shareholder Services, L.L.C., as Rights Agent (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 shall be canceled and
shall cease to exist, and no stock of Parent or other consideration shall be
delivered in exchange therefor.

        (c)  CONVERSION OF COMPANY COMMON STOCK.  Subject to the provisions of
this Section 2.1, each share of Company Common Stock, other than Dissenting
Shares (as defined in Section 2.1(n)) and shares canceled pursuant to Section
2.1(b), issued and outstanding immediately prior to the Effective Time shall by
virtue of the Merger and without any action on the part of the holder thereof,
be converted into the right to receive (i) $41.00 in cash (the "Cash
Consideration") or (ii) a number of validly issued, fully paid and nonassessable
shares of Common Stock, par value $.01 per share, of Parent ("Parent Common
Stock") equal to the Exchange Ratio (as defined below) (the "Stock
Consideration") or (iii) the right to receive a combination of cash and shares
of Parent Common Stock determined in accordance with this Section (the "Mixed
Consideration"). The "Exchange Ratio" shall

                                      A-2
<PAGE>
be equal to the Cash Consideration divided by either (i) the Parent Share Price
(as defined below) if the Parent Share Price is equal to or less than $30.13 and
equal to or more than $23.67, (ii) $30.13 if the Parent Share Price is greater
than $30.13, in which case the Exchange Ratio shall equal 1.3609, or (iii)
$23.67 if the Parent Share Price is less than $23.67, in which case the Exchange
Ratio shall equal 1.7320. The "Parent Share Price" shall be equal to the average
of the closing prices of the shares of Parent Common Stock on the New York Stock
Exchange ("NYSE") Composite Transactions Reporting System, as reported in The
Wall Street Journal, for the 20 trading days immediately preceding the second
trading day prior to the Effective Time.

        (d)  CASH ELECTION.  Subject to the immediately following sentence, each
record holder of shares of Company Common Stock immediately prior to the
Effective Time shall be entitled to elect to receive cash for all or any part of
such holder's shares of Company Common Stock (a "Cash Election").
Notwithstanding the foregoing and subject to Section 2.1(l), the aggregate
number of shares of Company Common Stock that may be converted into the right to
receive cash in the Merger (the "Cash Election Number") plus any Dissenting
Shares shall be 55% of the total number of shares of Company Common Stock issued
and outstanding as of the Effective Time. Cash Elections shall be made on a form
designed for that purpose (a "Form of Election"). A holder of record of shares
of Company Common Stock who holds such shares as nominee, trustee or in another
representative capacity (a "Representative") may submit multiple Forms of
Election, provided that such Representative certifies that each such Form of
Election covers all the shares of Company Common Stock held by such
Representative for a particular beneficial owner.

        (e)  CASH ELECTION SHARES.  If the aggregate number of shares of Company
Common Stock covered by Cash Elections (the "Cash Election Shares") exceeds the
Cash Election Number, each Cash Election Share shall be converted into (i) the
right to receive an amount in cash, without interest, equal to the product of
(A) the Cash Consideration and (B) a fraction (the "Cash Fraction"), the
numerator of which shall be the Cash Election Number and the denominator of
which shall be the total number of Cash Election Shares, and (ii) a number of
shares of Parent Common Stock equal to the product of (A) the Exchange Ratio and
(B) a fraction equal to one minus the Cash Fraction.

        (f)  STOCK ELECTION.  Subject to the immediately following sentence,
each record holder of shares of Company Common Stock immediately prior to the
Effective Time shall be entitled to elect to receive shares of Parent Common
Stock for all or any part of such holder's shares of Company Common Stock (a
"Stock Election"). Notwithstanding the foregoing and subject to Section 2.1(l),
the aggregate number of shares of Company Common Stock that may be converted
into the right to receive shares of Parent Common Stock in the Merger (the
"Stock Election Number") shall be 45% of the total number of shares of Company
Common Stock issued and outstanding as of the close of business on the third
trading day prior to the Effective Time. Stock Elections shall be made on a Form
of Election. A Representative may submit multiple Forms of Election, provided
that such Representative certifies that each such Form of Election covers all
the shares of Company Common Stock held by such Representative for a particular
beneficial owner.

        (g)  STOCK ELECTION SHARES.  If the aggregate number of shares of
Company Common Stock covered by Stock Elections (the "Stock Election Shares")
exceeds the Stock Election Number, each Stock Election Share shall be converted
into (i) the right to receive a number of shares of Parent Common Stock, equal
to the product of (A) the Exchange Ratio and (B) a fraction (the "Stock
Fraction"), the numerator of which shall be the Stock Election Number and the
denominator of which shall be the total number of Stock Election Shares, and
(ii) an amount in cash, without interest, equal to the product of (A) the Cash
Consideration and (B) a fraction equal to one minus the Stock Fraction.

                                      A-3
<PAGE>
        (h)  MIXED ELECTION.  Subject to the immediately following sentence,
each record holder of shares of Company Common Stock immediately prior to the
Effective Time shall be entitled to elect to receive shares of Parent Common
Stock for part of such holder's shares of Company Common Stock and cash for the
remaining part of such holder's shares of Company Common Stock (the "Mixed
Election" and, collectively with Stock Election and Cash Election, the
"Election"). Notwithstanding the foregoing and subject to Section 2.1(l), the
aggregate number of shares of Company Common Stock that may be converted into
the right to receive the Cash Consideration plus Dissenting Shares shall be 55%,
and the number of shares of Company Common Stock converted into the right to
receive the Stock Election Number shall be 45%, in each case, of the total
number of shares of Company Common Stock issued and outstanding as of the
Effective Time. Mixed Elections shall be made on a Form of Election. A
Representative may submit multiple Forms of Election, provided that such
Representative certifies that each such Form of Election covers all the shares
of Company Common Stock held by such Representative for a particular beneficial
owner. With respect to each holder of Company Common Stock who makes a Mixed
Election, the shares of Company Common Stock such holder elects to be converted
into the right to receive Cash Consideration shall be treated as Cash Election
Shares for purposes of the provisions contained in Sections 2.1(d), (e) and (l),
and the shares such holder elects to be converted into the right to receive
shares of Parent Common Stock shall be treated as Stock Election Shares for
purposes of the provisions contained in Sections 2.1(f), (g) and (l).

        (i)  FORM OF ELECTION.  To be effective, a Form of Election must be
properly completed, signed and submitted to Parent's transfer agent and
registrar, as paying agent (the "Paying Agent"), and accompanied by the
certificates representing the shares of Company Common Stock ("Company
Certificates") as to which the election is being made (or by an appropriate
guarantee of delivery of such Company Certificate signed by a firm that is a
member of any registered national securities exchange or a member of the
National Association of Securities Dealers, Inc. or a bank, broker, dealer,
credit union, savings association or other entity that is a member in good
standing of the Securities Transfer Agent's Medallion Program, the New York
Stock Exchange Medallion Signature Guarantee Program or the Stock Exchange
Medallion Program). Parent shall have the discretion, which it may delegate in
whole or in part to the Paying Agent, to determine whether Forms of Election
have been properly completed, signed and submitted or revoked and to disregard
immaterial defects in Forms of Election. The decision of Parent (or the Paying
Agent) in such matters shall be conclusive and binding. Neither Parent nor the
Paying Agent shall be under any obligation to notify any person of any defect in
a Form of Election submitted to the Paying Agent. The Paying Agent shall also
make all computations contemplated by this Section 2.1, and all such
computations shall be conclusive and binding on the holders of shares of Company
Common Stock.

        (j)  DEEMED NON-ELECTION.  For the purposes hereof, a holder of shares
of Company Common Stock who does not submit a Form of Election that is received
by the Paying Agent prior to the Election Deadline (as defined in Section
2.1(k)) (the "No Election Shares") shall be deemed not to have made a Cash
Election, Stock Election or Mixed Election. If Parent or the Paying Agent shall
determine that any purported Election was not properly made, the shares subject
to such improperly made Election shall be treated as No Election Shares. No
Election Shares may be treated by the Company as Cash Election Shares or Stock
Election Shares.

        (k)  ELECTION DEADLINE.  Parent and the Company shall each use its best
efforts to cause copies of the Form of Election to be mailed to the record
holders of the Company Shares not less than thirty days prior to the Effective
Time and to make the Form of Election available to all persons who become record
holders of Company Shares subsequent to the date of such mailing and no later
than the close of business on the seventh business day prior to the Effective
Time. A Form of Election must be received by the Paying Agent by 5:00 p.m., New
York City time, on the second day after the

                                      A-4
<PAGE>
Effective Time (the "Election Deadline") in order to be effective. All elections
may be revoked until the Election Deadline in writing by the record holders
submitting Forms of Election.

        (l)  ADJUSTMENT PER TAX OPINION.  Notwithstanding anything in this
Article II to the contrary (other than the last sentence of Section 2.1(m)), the
number of shares of Company Common Stock to be converted into the right to
receive the Stock Consideration in the Merger shall be not less than that number
which would cause the ratio of (i) the closing price per share of Parent Common
Stock on the Closing Date times the aggregate number of shares of Parent Common
Stock to be paid as Stock Consideration pursuant to Section 2.1(c), to (ii) the
sum of (A) the amount set forth in the preceding clause (i) plus (B) the
aggregate Cash Consideration to be issued pursuant to Section 2.1(c) plus (C)
the number of Dissenting Shares times the per share Cash Consideration plus (D)
any other amounts paid by Parent or the Company (or any affiliate thereof) to,
or on behalf of, any Company shareholder in connection with the sale, redemption
or other disposition of any Company stock in connection with the Merger for
purposes of Treasury Regulation Sections 1.368-1(e) and 1.368-1T(e) plus (E) any
extraordinary dividend distributed by the Company prior to and in connection
with the Merger for purposes of Treasury Regulation Sections 1.368-1(e) and
1.368-1T(e), to be 45%. To the extent the application of this Section 2.1(l)
results in the number of shares of Company Common Stock to be converted into the
right to receive the Stock Consideration in the Merger being increased, the
number of such shares to be converted into the right to receive the Cash
Consideration will be reduced.

        (m)  ANTI-DILUTION PROVISIONS.  In the event Parent (i) changes (or
establishes a record date for changing) the number of shares of Parent Common
Stock issued and outstanding prior to the Effective Time as a result of a stock
split, stock dividend, stock combination, recapitalization, reclassification,
reorganization or similar transaction with respect to the outstanding Parent
Common Stock or (ii) pays or makes an extraordinary dividend or distribution in
respect of Parent Common Stock (other than a distribution referred to in clause
(i) of this sentence) and, in either case, the record date therefor shall be
prior to the Effective Time, the Merger Consideration (as defined in Section
2.2(b)) shall be proportionately adjusted. Regular quarterly cash dividends and
increases thereon shall not be considered extraordinary for purposes of the
preceding sentence. If, between the date hereof and the Effective Time, Parent
shall merge or consolidate with or into any other corporation (a "Business
Combination") and the terms thereof shall provide that Parent Common Stock shall
be converted into or exchanged for the shares of any other corporation or
entity, then provision shall be made so that shareholders of the Company who
would be entitled to receive shares of Parent Common Stock pursuant to this
Agreement shall be entitled to receive, in lieu of each share of Parent Common
Stock issuable to such shareholders as provided herein, the same kind and amount
of securities or assets as shall be distributable upon such Business Combination
with respect to one share of Parent Common Stock and the parties hereto shall
agree on an appropriate restructuring of the transactions contemplated herein.

        (n)  DISSENTING SHARES.  Each outstanding share of Company Common Stock
the holder of which has perfected his right to dissent under applicable law and
has not effectively withdrawn or lost such right as of the Effective Time (the
"Dissenting Shares") shall not be converted into or represent a right to receive
the Merger Consideration, and the holder thereof shall be entitled only to such
rights as are granted by applicable law; provided, however, that any Dissenting
Share held by a person at the Effective Time who shall, after the Effective
Time, withdraw the demand for payment for shares or lose the right to payment
for shares, in either case pursuant to the CBCA, shall be deemed to be converted
into, as of the Effective Time, the right to receive cash pursuant to Section
2.1(c) in the same manner as if such shares were Cash Election Shares. The
Company shall give Parent prompt notice upon receipt by the Company of any such
written demands for payment of the fair value of such shares of

                                      A-5
<PAGE>
Company Common Stock and of withdrawals of such notice and any other instruments
provided pursuant to applicable law. Any payments made in respect of Dissenting
Shares shall be made by the Surviving Corporation.

    Section 2.2  EXCHANGE OF CERTIFICATES.

        (a)  DEPOSIT WITH EXCHANGE AGENT.  As soon as practicable after the
Effective Time, the Surviving Corporation shall deposit with a bank or trust
company mutually agreeable to Parent and the Company (the "Exchange Agent"),
pursuant to an agreement in form and substance reasonably acceptable to Parent
and the Company, an amount of cash and certificates representing shares of
Parent Common Stock required to effect the conversion of Company Common Stock
into Parent Common Stock and cash in accordance with Section 2.1(c).

        (b)  EXCHANGE AND PAYMENT PROCEDURES.  As soon as practicable after the
Effective Time, Parent shall cause the Paying Agent to mail to each holder of
record as of the Effective Time of a Certificate or Certificates that have been
converted pursuant to Section 2.1: (i) a letter of transmittal (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 and receiving the Merger Consideration (as defined below) to which
such holder shall be entitled therefor pursuant to Section 2.1. Upon surrender
of a Certificate to the Paying Agent for cancellation, together with a duly
executed letter of transmittal and such other documents as the Paying Agent may
require, the holder of such Certificate shall be entitled to receive in exchange
therefor (i) a certificate representing that number of shares of Parent Common
Stock (the "Parent Shares") into which the shares of Company Common Stock
previously represented by such Certificate are converted in accordance with
Section 2.1(c), (ii) the cash to which such holder is entitled in accordance
with Section 2.1(c), and (iii) the cash in lieu of fractional Parent Shares to
which such holder has the right to receive pursuant to Section 2.2(d) (the
shares of Parent Common Stock and cash described in clauses (i), (ii) and (iii)
above being referred to collectively as the "Merger Consideration"). In the
event the Merger Consideration is to be delivered to any person who is not the
person in whose name the Certificate surrendered in exchange therefor is
registered in the transfer records of Company, the Merger Consideration may be
delivered to a transferee if the Certificate 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. Until surrendered as contemplated by this Section 2.2,
each Certificate (other than a certificate representing shares of Company Common
Stock to be canceled in accordance with Section 2.1(b)) shall be deemed at any
time after the Effective Time to represent only the right to receive upon such
surrender the Merger Consideration contemplated by this Section 2.2. No interest
will be paid or will accrue on any cash payable to holders of Certificates
pursuant to provisions of this Article II.

        (c)  DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES.  No dividends or
other distributions declared or made after the Effective Time with respect to
Parent Shares with a record date after the Effective Time shall be paid to the
holder of any unsurrendered Certificate with respect to the Parent Shares
represented thereby and no cash payment in lieu of fractional shares shall be
paid to any such holder pursuant to Section 2.2(d) until the holder of record of
such Certificate shall surrender such Certificate. Subject to the effect of
unclaimed property, escheat and other applicable laws, following surrender of
any such Certificate, there shall be paid to the record holder of the
certificates representing whole Parent Shares issued in exchange therefor,
without interest, (i) at the time of such surrender, the amount of any cash
payable in lieu of a fractional share of Parent Common Stock to which such
holder is entitled pursuant to Section 2.2(d) and the amount of dividends or
other

                                      A-6
<PAGE>
distributions with a record date after the Effective Time theretofore paid with
respect to such whole Parent Shares and (ii) at the appropriate payment date,
the amount of dividends or other distributions with a record date after the
Effective Time but prior to surrender and a payment date subsequent to surrender
payable with respect to such whole Parent Shares.

        (d)  NO FRACTIONAL SECURITIES.  In lieu of any such fractional
securities, each holder of Company Common Stock who would otherwise have been
entitled to a fraction of a share of Parent Common Stock upon surrender of
Certificates for exchange pursuant to this Article II will be paid an amount in
cash (without interest) equal to such holder's proportionate interest in the net
proceeds from the sale or sales in the open market by the Exchange Agent, on
behalf of all such holders, of the aggregate fractional shares of Parent Common
Stock issued pursuant to this Article II. As soon as practicable following the
Effective Time, the Exchange Agent shall determine the excess of (i) the number
of full shares of Parent Common Stock delivered to the Exchange Agent by Parent
over (ii) the aggregate number of full shares of Parent Common Stock to be
distributed to holders of Company Common Stock (such excess being herein called
the "Excess Parent Common Shares"). The Exchange Agent, as agent for the former
holders of Company Common Stock, shall sell the Excess Parent Common Shares at
the prevailing prices on the NYSE. The sales of the Excess Parent Common Shares
by the Exchange Agent shall be executed on the NYSE through one or more member
firms of the NYSE and shall be executed in round lots to the extent practicable.
Parent shall pay all commissions, transfer taxes and other out-of-pocket
transaction costs, including the expenses and compensation of the Exchange
Agent, incurred in connection with such sale of Excess Parent Common Shares.
Until the net proceeds of such sale have been distributed to the former holders
of Company Common Stock, the Exchange Agent will hold such proceeds in trust for
such former holders. As soon as practicable after the determination of the
amount of cash to be paid to former holders of Company Common Stock in lieu of
any fractional interests, the Exchange Agent shall make available in accordance
with this Agreement such amounts to such former holders.

        (e)  CLOSING OF TRANSFER BOOKS.  If, after the Effective Time,
Certificates are presented to the Surviving Corporation, they shall be canceled
and exchanged for certificates representing the appropriate number of Parent
Shares and the appropriate amount of cash as provided in Section 2.1 and in this
Section 2.2.

        (f)  TERMINATION OF EXCHANGE AGENT.  Any certificates representing
Parent Shares deposited with the Exchange Agent pursuant to Section 2.2(a) and
not exchanged within six months after the Effective Time pursuant to this
Section 2.2 shall be returned by the Exchange Agent to Parent, which shall
thereafter act as Exchange Agent. All funds held by the Exchange Agent for
payment to the holders of unsurrendered Certificates and unclaimed at the end of
one year from the Effective Time shall be returned to the Surviving Corporation,
after which time any holder of unsurrendered Certificates shall look as a
general creditor only to Parent for payment of such funds to which such holder
may be due, subject to applicable law.

        (g)  ESCHEAT.  The Company shall not be liable to any person for such
shares or funds delivered to a public official pursuant to any applicable
abandoned property, escheat or similar law.

           (iv) A "Plan" means any Employee Benefit Plan other than a
       Multiemployer Plan.

           (v) A "Multiemployer Plan" means any "multiemployer plan" within the
       meaning of Section 4001(a)(3) of ERISA.

           (vi) "Withdrawal Liability" means liability to a Multiemployer Plan
       as a result of a complete or partial withdrawal from such Multiemployer
       Plan, as those terms are defined in Part I of Subtitle E of Title IV of
       ERISA.

        (b) Section 4.10(b) of the Company Disclosure Schedule includes a
    complete list of all material Employee Benefit Plans and, with respect to
    executive welfare benefit plans and nonqualified pension, savings and
    deferred compensation plans, states the number of employees participating in
    or covered by such plans.

        (c) With respect to each Plan, the Company has delivered to Parent a
    true, correct and complete copy of: (i) each writing constituting a part of
    such Plan, including without limitation all material plan documents, trust
    agreements, and insurance contracts and other funding vehicles; (ii) the
    most recent Annual Report (Form 5500 Series) and accompanying schedules, if
    any; (iii) the current summary plan description and any material
    modifications thereto, if required to be furnished under ERISA; (iv) the
    most recent annual financial report, if any; (v) the most recent actuarial
    report, if any; and (vi) the most recent determination letter from the
    Internal Revenue Service (the "IRS"), if any. Except as specifically
    provided in the foregoing documents delivered to Parent, there are no
    amendments to any Plan that have been adopted or approved nor has the
    Company or any of its subsidiaries undertaken to make any such amendments or
    to adopt or approve any new Plan.

        (d) Section 4.10(b) of the Company Disclosure Schedule identifies each
    Plan that is intended to be a "qualified plan" within the meaning of Section
    401(a) of the Code ("Qualified Plans"). The IRS has issued a favorable
    determination letter with respect to each Qualified Plan and the related
    trust that has not been revoked, and except as would not have a Company
    Material Adverse Effect, there are no existing circumstances nor any events
    that have occurred that could adversely affect the qualified status of any
    Qualified Plan or the related trust. Section 4.10(b) of the Company
    Disclosure Schedule identifies each Plan or related trust which is intended
    to meet the requirements of Code Section 501(c)(9) (a "VEBA"), and except as
    would not have a Company Material Adverse Effect, each such VEBA meets such
    requirements and provides no disqualified benefits (as such term is defined
    in Code Section 4976(b)).

        (e) All material contributions required to be made to any Plan by
    applicable law or regulation or by any Plan document or other contractual
    undertaking, and all material premiums due or payable with respect to
    insurance policies funding any Plan, for any period through the date hereof
    have been timely made or paid in full or, to the extent not required to be
    made or paid on or before the date hereof, have been fully reflected on the
    Company Financial Statements. Each Plan that is an employee welfare benefit
    plan under Section 3(1) of ERISA (i) is funded through an insurance company
    contract or a contract with a health maintenance organization, (ii) is, or
    is funded through, a VEBA identified as such in Section 4.10(b) of the
    Company Disclosure Schedule, or (iii) is unfunded.

        (f) Except as would not have a Company Material Adverse Effect, with
    respect to each Employee Benefit Plan, the Company and its subsidiaries have
    complied, and are now in compliance, with all provisions of ERISA, the Code
    and all laws and regulations applicable to such Employee Benefit Plans and
    each Plan has been administered in all material respects in accordance with
    its terms. There is not now, nor do any circumstances exist that could
    reasonably be expected to give rise to, any requirement for the posting of
    security with respect to a Plan or the imposition of any lien on the assets
    of the Company or any of its subsidiaries under ERISA or

                                      A-14
<PAGE>
    the Code. To the knowledge of the Company, no non-exempt prohibited
    transaction (as defined in Section 406 of ERISA or Section 4975 of the Code)
    has occurred with respect to any Plan.

        (g) With respect to each Plan that is subject to Title IV of ERISA, the
    minimum funding requirements of Section 302 of ERISA or Section 412 of the
    Code, or Section 4971 of the Code: (i) there does not exist any accumulated
    funding deficiency within the meaning of Section 412 of the Code or Section
    302 of ERISA, whether or not waived, in respect of any plan year ended prior
    to the date hereof and for which the time for making contributions in order
    to avoid occurring an accumulated funding deficiency for such year has
    expired; (ii) the fair market value of the assets of each such Plan that is
    a defined benefit plan equals or exceeds the actuarial present value of the
    accumulated benefit obligation (as of the date of the most recent actuarial
    report prepared for such Plan) under such Plan (whether or not vested),
    based upon the actuarial assumptions set forth in the most recent actuarial
    report for such Plan; (iii) no reportable event within the meaning of
    Section 4043(c) of ERISA for which the 30-day notice requirement has not
    been waived has occurred since December 31, 1993 in respect of any such Plan
    which is a defined benefit Plan; (iv) all material premiums to the Pension
    Benefit Guaranty Corporation ("PBGC") have been timely paid in full; (v) no
    material liability (other than for premiums to the PBGC and for the payment
    of benefits and contributions in the ordinary course) under Title IV of
    ERISA has been or could reasonably be expected to be incurred by the Company
    or any of its subsidiaries; and (vi) to the knowledge of the Company, the
    PBGC has not instituted proceedings to terminate any such Plan and no
    condition exists that presents a material risk that such proceedings will be
    instituted or which would constitute grounds under Section 4042 of ERISA for
    the termination of, or the appointment of a trustee to administer, any such
    Plan.

        (h) No Employee Benefit Plan is a Multiemployer Plan or a plan that has
    two or more contributing sponsors at least two of which are not under common
    control, within the meaning of Section 4063 of ERISA (a "Multiple Employer
    Plan"). None of the Company and its subsidiaries nor any of their respective
    ERISA Affiliates has, at any time during the last six years, contributed to
    or been obligated to contribute to any Multiemployer Plan or Multiple
    Employer Plan. None of the Company and its subsidiaries nor any ERISA
    Affiliates has incurred any Withdrawal Liability that has not been satisfied
    in full.

        (i) There does not now exist, nor do any circumstances exist that could
    reasonably be expected to result in, any Controlled Group Liability that
    would have a Company Material Adverse Effect following the Closing. Without
    limiting the generality of the foregoing, neither the Company nor any of its
    subsidiaries, nor any of their respective ERISA Affiliates, has engaged in
    any transaction described in Section 4069 or Section 4204 or 4212 of ERISA
    since December 31, 1993.

        (j) Except for health continuation coverage as required by Section 4980B
    of the Code or Part 6 of Title I of ERISA or applicable state law, the
    Company and its subsidiaries have no material liability for life, health,
    medical or other welfare benefits to former employees or beneficiaries or
    dependents of former employees.

        (k) Neither the execution and delivery of this Agreement nor the
    consummation of any of the transactions contemplated hereby will (either
    alone or in conjunction with any other event) result in, cause the
    accelerated funding, vesting or delivery of, or increase the amount or value
    of, any material payment or benefit to any employee, officer or director of
    the Company or any of its subsidiaries. Section 4.10(k) of the Company
    Disclosure Schedule sets forth the estimated amount that will be required to
    be contributed to each trust listed thereon as a result of the consummation
    of the transactions contemplated hereby.

        (l) 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

                                      A-15
<PAGE>
    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. There are no organizing activities, strikes, work stoppages,
    slowdowns, lockouts, material arbitrations or material grievances, or other
    material labor disputes pending or, to the knowledge of the Company,
    threatened against or involving the Company or any of its subsidiaries. Each
    of the Company and its subsidiaries is in compliance in all material
    respects with all applicable laws and collective bargaining agreements
    respecting employment and employment practices, terms and conditions of
    employment, wages and hours and occupational safety and health.

        (m) There are no pending or, to the knowledge of the Company, threatened
    claims (other than claims for benefits in the ordinary course), lawsuits or
    arbitrations which have been asserted or instituted, and there is no set of
    circumstances which may reasonably give rise to a claim or lawsuit, against
    the Plans, any fiduciaries thereof with respect to their duties to the Plans
    or the assets of any of the trusts under any of the Plans which could
    reasonably be expected to result in a Company Material Adverse Effect.

        (n) The Company, its subsidiaries and each member of their respective
    business enterprise has complied with the Worker Adjustment and Retraining
    Notification Act.

    all terms and conditions of the Environmental Permits, and the Company
    reasonably believes that any transfer, renewal or reapplication for any
    Environmental Permit required as a result of the Merger can be accomplished

    be in such compliance would not, in the aggregate, have a Company Material
    Adverse Effect.

        (c)  ENVIRONMENTAL CLAIMS.  There are no Environmental Claims (as
    defined in Section 4.11(f)(i)) pending (i) against the Company or any of its
    subsidiaries or joint ventures, or (ii) against any real or personal
    property or operations that the Company or any of its subsidiaries owns,
    leases or manages, in whole or in part that, if adversely determined, would
    have, in the aggregate, a Company Material Adverse Effect.

        (d)  RELEASES.  Except for Releases of Hazardous Materials the liability

    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

Adverse Effect (the "Parent Required Statutory Approvals"), it being understood
that references in this Agreement to "obtaining" such Parent Required Statutory
Approvals shall mean making such declarations, filings or registrations; giving
such notices; obtaining such authorizations, consents or approvals; and having
such waiting periods expire as are necessary to avoid a violation of law.

        (d)  COMPLIANCE.  Except as set forth in Section 5.4(d) or Section 5.11

expertise through the use of specialized employment and benefit plans designed
for that specific purpose; PROVIDED, HOWEVER, that the result of the use of such
specialized employment or benefit plans shall not, in the aggregate, result in
payments in excess of $600,000.

advisor and based upon the advice of outside counsel and such other matters as
the Board of Directors of the Company deems relevant, that failure to do so
would likely result in a breach of its fiduciary duties under applicable law,
and (B) prior to furnishing such information to, or entering into discussions or

to, or intends to enter into discussions or negotiations with, such person or
entity, (y) provides the Parent a reasonable opportunity to respond to the

will not permit any subsidiary to, and will use reasonable best efforts to cause

registration with, or notice to or authorization, consent or approval of, any
Governmental Authority in connection with the consummation by Parent, Merger Sub
or the Company of the transactions contemplated by this Agreement, other than
those set forth in Section 5.4(c) of the Parent Disclosure Schedule or Section

federal or state securities laws or filed with or sent to the SEC, the FERC, the
Department of Justice, the Federal Trade Commission or any other federal or
state regulatory agency or commission, and (b) access to all information
concerning themselves, their subsidiaries, directors, officers and shareholders
and such other matters as may be reasonably requested by the other party in
connection with any filings, applications or approvals required or contemplated
by this Agreement. Each party shall, and shall cause its subsidiaries and
Representatives to, hold in strict confidence all Proprietary Information (as
defined in the Confidentiality Agreement) concerning the other parties furnished
to it in connection with the transactions contemplated by this Agreement in
accordance with the Confidentiality Agreement, dated as of June 18, 1999,
between the Company and Parent, as it may be amended from time to time (the
"Confidentiality Agreement").

    Section 7.2  PROXY STATEMENT AND REGISTRATION STATEMENT.

        (a)  PREPARATION AND FILING.  The parties will prepare and file with the
SEC as soon as reasonably practicable after the date hereof the Registration
Statement and the Proxy Statement (together, the "Proxy/Registration
Statement"). The parties hereto shall each use reasonable efforts to cause the
Registration Statement to be declared effective under the Securities Act as
promptly as practicable after such filing. Each party hereto shall also take
such action as may be reasonably required to cause the shares of Parent Common
Stock issuable in connection with the Merger to be registered or to obtain an
exemption from registration under applicable state "blue sky" or securities
laws; provided, however, that no party shall be required to register or qualify
as a foreign corporation or to take other action which would subject it to
service of process in any jurisdiction where it will not be, following the
Merger, so subject. Each of the parties hereto shall furnish all information
concerning itself which is required or customary for inclusion in the
Proxy/Registration Statement. The parties shall use reasonable efforts to cause
the shares of Parent Common Stock issuable in the Merger to be approved for
listing on the NYSE upon official notice of issuance. The information provided
by any party hereto for use in the Proxy/Registration Statement shall be true
and correct in all material respects without omission of any material fact which
is required to make such information not false or misleading. No representation,
covenant or agreement is made by or on behalf of any party hereto with respect
to information supplied by any other party for inclusion in the Proxy
Statement/Registration Statement.

        (b)  LETTER OF THE COMPANY'S ACCOUNTANT.  Following receipt by Arthur
Andersen LLP, the Company's independent auditor, of an appropriate request from
the Company pursuant to SAS No. 72, the Company shall use its best efforts to
cause to be delivered to Parent a letter of Arthur Andersen LLP dated a date
within two business days before the date of the Proxy/Registration Statement,
and addressed to Parent, in form and substance reasonably satisfactory to Parent
and customary in scope and substance for "cold comfort" letters delivered by
independent public accountants in connection with registration statements
similar to the Proxy/Registration Statement.

        (c)  LETTER OF PARENT'S ACCOUNTANT.  Following receipt by
PricewaterhouseCoopers LLP, Parent's independent auditor, of an appropriate
request from Parent pursuant to SAS No. 72, Parent shall use its best efforts to
cause to be delivered to the Company a letter of PricewaterhouseCoopers

                                      A-28
<PAGE>
LLP, dated a date within two business days before the date of the
Proxy/Registration Statement, and addressed to the Company, in form and
substance reasonably satisfactory to the Company and customary in scope and
substance for "cold comfort" letters delivered by independent public accountants
in connection with registration statements similar to the Proxy/Registration
Statement.

    Section 7.3  REGULATORY MATTERS.  Each party hereto shall cooperate and use
its 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 no later
than the Initial Termination Date, as such date may be extended pursuant to
Section 9.1(b), all necessary permits, consents, approvals and authorizations of
all Governmental Authorities necessary or advisable to consummate the
transactions contemplated by this Agreement, including, without limitation, the
Company Required Statutory Approvals and the Parent Required Statutory
Approvals.

    Section 7.4  COMPANY SHAREHOLDERS' APPROVAL.

        (a)  COMPANY SPECIAL MEETING.  Subject to the provisions of Section
7.4(b), the Company shall, as soon as reasonably practicable after the date
hereof (i) take all steps necessary to duly call, give notice of, convene and
hold a meeting of its shareholders (the "Company Special Meeting") for the
purpose of securing the Company Shareholders' Approval, (ii) distribute to its
shareholders the Proxy Statement in accordance with applicable federal and state
law and with its certificate of incorporation and by-laws, (iii) subject to the
fiduciary duties of its Board of Directors, recommend to its shareholders the
approval of this Agreement and the transactions contemplated hereby and (iv)
cooperate and consult with Parent with respect to each of the foregoing matters.

        (b)  MEETING DATE.  The Company Special Meeting for the purpose of
securing the Company Shareholders' Approval shall be held on such date as the
Company and Parent shall mutually determine.

    Section 7.5  DIRECTORS' AND OFFICERS' INDEMNIFICATION.

        (a)  INDEMNIFICATION.  To the extent, if any, not provided by an
existing right of indemnification or other agreement or policy, from and after
the Effective Time, Parent and the Surviving Corporation shall, to the fullest
extent permitted by applicable law, indemnify, defend and hold harmless each
person who is now, or has been at any time prior to the date hereof, or who
becomes prior to the Effective Time, an officer, director or employee of the
Company or any of its subsidiaries (each an "Indemnified Party" and
collectively, the "Indemnified Parties") against (i) all losses, expenses
(including reasonable attorney's fees and expenses), claims, damages or
liabilities or, subject to the proviso of the next succeeding sentence, 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), (i) Parent shall pay 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, (ii) any determination required to be
made with respect to whether an Indemnified Party's conduct complies with the
standards set forth in Section 33-756, 33-757 and 33-765 of the CBCA, and the
certificate of incorporation or by-laws shall be made by independent counsel
mutually acceptable to Parent and the Indemnified Party; provided, however, that
Parent shall not be liable for any settlement effected without its written
consent (which consent shall not be unreasonably withheld). The Indemnified
Parties as a group may retain only one law firm with respect to each related
matter except to the extent there is, in the opinion of counsel to an
Indemnified Party, under

                                      A-29
<PAGE>
applicable standards of professional conduct, a conflict on any significant
issue between positions of such Indemnified Party and any other Indemnified
Party or Indemnified Parties.

        (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 of six years for acts prior to the
Effective Time on terms no less favorable than the terms of such current
insurance coverage; provided, however, that Parent shall not be required to
expend in any year an amount in excess of 200% of the annual aggregate premiums
currently paid by the Company, for such insurance; and provided, further, that
if the annual premiums of such insurance coverage exceed such amount, Parent
shall be obligated to obtain a policy with the best coverage available, in the
reasonable judgment of the Board of Directors of Parent, for a cost not
exceeding 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 7.5.

        (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 organization 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 7.5 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 7.6  DISCLOSURE SCHEDULES.  On the date hereof, (a) Parent has
delivered to the Company a schedule (the "Parent Disclosure Schedule"),
accompanied by a certificate signed by the Executive Vice President and General
Counsel of Parent stating the Parent Disclosure Schedule is being delivered
pursuant to this Section 7.6(a), and (b) the Company has delivered to Parent a
schedule (the "Company Disclosure Schedule"), accompanied by a certificate
signed by the Vice President, General Counsel and Secretary of the Company
stating the Company Disclosure Schedule is being delivered pursuant to this
Section 7.6(b). The Company Disclosure Schedule and the Parent Disclosure
Schedule are collectively referred to herein as the "Disclosure Schedules." The
Disclosure Schedules constitute an integral part of this Agreement and modify
the respective representations, warranties, covenants or agreements of the
parties hereto contained herein to the extent that such representations,
warranties, covenants or agreements expressly refer to the Disclosure Schedules.
Anything to the contrary contained herein or in the Disclosure Schedules
notwithstanding, any and all statements, representations, warranties or
disclosures set forth in the Disclosure Schedules shall be deemed to have been
made on and as of the date hereof.

    Section 7.7  PUBLIC ANNOUNCEMENTS.  Subject to each party's disclosure
obligations imposed by law, 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).

                                      A-30
<PAGE>
    Section 7.8  RULE 145 AFFILIATES.  Within 30 days after the date of this
Agreement, the Company shall identify in a letter to Parent all persons who are,
and to such person's best knowledge who will be at the Closing Date,
"affiliates" of the Company, as such term is used in Rule 145 under the
Securities Act. The Company shall use all reasonable efforts to cause its
affiliates (including any person who may be deemed to have become an affiliate
after the date of the letter referred to in the prior sentence) to deliver to
Parent on or prior to the Closing Date a written agreement substantially in the
form attached as Exhibit 7.8 (each, an "Affiliate Agreement").

    Section 7.9  CERTAIN EMPLOYEE AGREEMENTS.  Subject to Section 7.10, Parent
and the Surviving Corporation and its subsidiaries shall honor, without
modification, all contracts, agreements, collective bargaining agreements and
commitments of the parties which apply to any current or former employee or
current or former director of the parties hereto; 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. It is the present intention of
Parent and the Company that following the Effective Time, there will be no
involuntary reductions in force at the Surviving Corporation or its
subsidiaries, but that Parent, the Surviving Corporation and their respective
subsidiaries will continue Parent's and the Company's present strategy of
achieving workforce reductions through attrition; however, if any reductions in
workforce in respect of employees of Parent and its subsidiaries, including the
Surviving Corporation and its subsidiaries, become necessary, they shall be made
on a fair and equitable basis, in light of the circumstances and the objectives
to be achieved, giving consideration to previous work history, job experience,
qualifications, and business needs without regard to whether employment prior to
the Effective Time was with the Company or its subsidiaries or Parent or its
subsidiaries, and any employees whose employment is terminated or jobs are
eliminated by Parent, the Surviving Corporation or any of their respective
subsidiaries shall be entitled to participate on a fair and equitable basis in
the job opportunity and employment placement programs offered by Parent, the
Surviving Corporation or any of their respective subsidiaries. Any workforce
reductions carried out following the Effective Time by Parent or the Surviving
Corporation and their respective subsidiaries shall be done in accordance with
all applicable collective bargaining agreements, and all laws and regulations
governing the employment relationship and termination thereof including, without
limitation, the Worker Adjustment and Retraining Notification Act and
regulations promulgated thereunder, and any comparable state or local law.

    Section 7.10  EMPLOYEE BENEFIT PLANS.

        (a) Except as may be required by applicable law and except as provided
    in Section 7.11(b) with respect to the Stock Option Plan and Restricted
    Stock Plan, each Plan in effect on the date hereof (or as amended or
    established in accordance with or as permitted by this Agreement) shall be
    maintained in effect with respect to the employees, former employees,
    directors or former directors of the Company and any of its subsidiaries who
    are covered by such plans, programs, agreements or arrangements immediately
    prior to the Effective Time until Parent determines otherwise on or after
    the Effective Time, and Parent shall assume or cause the Surviving
    Corporation to assume as of the Effective Time each Plan maintained by the
    Company immediately prior to the Effective Time and perform such plan,
    program, agreement or arrangement in the same manner and to the same extent
    that the Company would be required to perform thereunder; PROVIDED, HOWEVER,
    that nothing herein contained shall limit any reserved right contained in
    any such Plan to amend, modify, suspend, revoke or terminate any such plan,
    program, agreement or arrangement; PROVIDED, FURTHER, that Parent or its
    subsidiaries shall provide to each employee of the Company and any of its
    subsidiaries who was covered by Plans immediately prior to the Effective
    Time and who is not covered by a collective bargaining agreement (a "Covered
    Company Employee") for a period of no less than 18 months following the

                                      A-31
<PAGE>
    Effective Time, employer-provided benefits under Qualified Plans,
    supplemental retirement benefit and deferred compensation plans which are
    not Qualified Plans and welfare plans that are no less favorable in the
    aggregate than those provided to the employee immediately prior to the
    Effective Time. Without limiting the foregoing, each Covered Company
    Employee who is a participant in any Plan shall receive credit for purposes
    of eligibility to participate, vesting and eligibility to receive benefits
    (but specifically excluding for benefit accrual purposes) under any
    replacement benefit plan of Parent or any of its subsidiaries or affiliates
    in which such employee becomes a participant for service credited for the
    corresponding purpose under any such Plan; PROVIDED, HOWEVER, that such
    crediting of service shall not operate to cause any such plan or agreement
    to fail to comply with the applicable provisions of the Code and ERISA. No
    provision contained in this Section 7.10 shall be deemed to constitute an
    employment contract between Parent or any of its subsidiaries and any
    individual, or a waiver of Parent's or any of its subsidiaries' right to
    discharge any employee at any time, with or without cause. Notwithstanding
    the foregoing, but subject to Section 7.10(b), Parent acknowledges that each
    Covered Company Employee who is a participant in the Connecticut Natural Gas
    Corporation Officers' Retirement Plan (the "SERP") as of the date hereof
    shall continue to accrue benefits after the Effective Time under terms at
    least as favorable as the terms of the SERP in effect on the date of this
    Agreement, taking into account service and compensation earned while
    employed by Parent and its subsidiaries after the Effective Time.

        (b) The Company shall take all necessary actions so that, effective no
    later than immediately before the Effective Time, (i) each of the SERP, the
    Connecticut Natural Gas Corporation Officers Deferred Compensation Plan, the
    Connecticut Natural Gas Corporation Executive Life Insurance Plan and all
    other executive benefit plans and programs of the Company and its
    subsidiaries shall be amended to the extent necessary so that any provisions
    therein that prohibit or limit the amendment or termination thereof
    following a change of control do not apply to individuals who are not
    participants therein as of the date of this Agreement and (ii) subject to
    applicable law and the provisions of any applicable collective bargaining
    agreement, each Qualified Plan shall be amended to the extent necessary so
    that any provisions therein that call for the waiver or elimination of
    vesting requirements upon or following a change in control shall apply only
    to individuals who are participants therein immediately before the Effective
    Time.

    Section 7.11  COMPANY STOCK AND OTHER PLANS.

        (a) With respect to each Plan that provides for benefits in the form of
    Company Common Stock ("Company Stock Plans"), the Company and Parent shall
    take all corporate action necessary or appropriate to (i) provide for the
    issuance or purchase in the open market of Parent Common Stock rather than
    Company Common Stock, pursuant thereto, and otherwise to amend such Company
    Stock Plans to reflect this Agreement and the Merger, (ii) obtain
    shareholder or board of director approval with respect to such Company Stock
    Plans to the extent such approval is required for purposes of the Code or
    other applicable law, or to enable such Company Stock Plans to comply with
    Rule 16b-3 promulgated under the Exchange Act, (iii) reserve for issuance
    under such Company Stock Plans or otherwise provide a sufficient number of
    shares of Parent Common Stock for delivery upon payment of benefits, grant
    of awards or exercise of options under such Company Stock Plans and (iv) as
    soon as practicable after the Effective Time, file registration statements
    on Form S-8 or amendments on such forms to the Form S-4 Registration
    Statement, as the case may be (or any successor or other appropriate forms),
    with respect to the shares of Parent Common Stock subject to such Company
    Stock Plans to the extent such registration statement is required under
    applicable law, and Parent shall use its best efforts to maintain the
    effectiveness of such registration statements (and maintain the current
    status of the prospectuses contained therein) for so long as such benefits
    and grants remain payable and such options remain outstanding. With respect
    to those individuals who subsequent to the Merger will be subject to the

                                      A-32
<PAGE>
    reporting requirements under Section 16(a) of the Exchange Act, the Company
    shall administer the Company Stock Plans, where applicable, in a manner that
    complies with Rule 16b-3 promulgated under the Exchange Act.

        (b) The Company and its subsidiaries and the Parent and its
    subsidiaries, including the Surviving Corporation and its subsidiaries,
    shall take all actions necessary to provide that upon the Effective Time (i)
    each outstanding option to purchase Company Common Stock granted under the
    Company's 1999 Stock Option Plan (the "Stock Option Plan"), whether or not
    then vested and exercisable, shall be canceled in exchange for a cash
    payment equal to (A) the excess of $41.00 over the exercise price thereof
    times (B) the number of shares of Company Common Stock subject thereto, less
    applicable tax withholding, and (ii) each outstanding restricted share of
    Company Common Stock granted under the Connecticut Natural Gas Corporation
    Executive Restricted Stock Plan (the "Restricted Stock Plan") shall become
    fully vested as provided in and subject to the terms of the award agreements
    relating thereto and simultaneously converted for Cash Consideration or
    Stock Consideration payable to the holder thereof as provided in Section 2.1
    hereof. The Company and its subsidiaries shall take all actions needed to
    terminate the Stock Option Plan and Restricted Stock Plan as of the
    Effective Time, subject, however, to the payments required under the
    preceding sentence.

        (c) Each employee of the Company who is a participant in the Company's
    Annual Incentive Plan and who is not a party to a Change of Control
    Employment Agreement with the Company is listed on Schedule 7.11(c) hereto
    (such employees, the "Schedule 7.11(c) Employees"). Following the Effective
    Time, each Schedule 7.11(c) Employee shall be entitled to participate in an
    annual incentive plan of Parent or any of its subsidiaries for the portion
    of the fiscal year of Parent or the applicable subsidiary in which the
    Effective Time occurs that follows the Effective Time (the "Post-Merger
    Period"), under which (i) the Schedule 7.11(c) Employee's award opportunity
    for the Post-Merger Period shall equal the percentage of the Schedule
    7.11(c) Employee's base salary set forth opposite the Schedule 7.11(c)
    Employee's name on Schedule 7.11(c), and (ii) the amount of such award
    opportunity that is earned shall be pro-rated based upon the number of days
    occurring in such fiscal year that occur during the Post-Merger Period.

    Section 7.12  EXPENSES.  Subject to Section 9.3, all costs and expenses
incurred in connection with this Agreement and the transactions contemplated
hereby shall be paid by the party incurring such expenses, except that those
expenses incurred in connection with printing the Proxy/Registration Statement,
as well as the filing fee relating thereto, shall be shared equally by the
Company and Parent.

    Section 7.13  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 7.14  CORPORATE OFFICES.  At and subsequent to the Effective Time,
the corporate headquarters of the Surviving Corporation shall be located in
Hartford, Connecticut. At and subsequent to the Effective Time, the corporate
headquarters of XENERGY Enterprises, Inc. shall be located in Connecticut.

                                      A-33
<PAGE>
    Section 7.15  PARENT BOARD OF DIRECTORS.  At the Effective Time, the Board
of Directors of Parent shall increase by one the number of directors on the
Board of Directors of Parent and shall thereupon elect as a director a
non-employee director of the Company designated by the Company and reasonably
acceptable to Parent.

    Section 7.16  COMMUNITY INVOLVEMENT.  After the Effective Time, Parent will,
or will cause the Surviving Corporation to make at least $500,000 per year in
charitable contributions to the communities served by the Surviving Corporation
and otherwise maintain a substantial level of involvement in community
activities in the State of Connecticut that is similar to, or greater than, the
level of community development and related activities carried on by the Company.

    Section 7.17  ADVISORY BOARD.  At the Effective Time, there shall be
established an advisory board to the Surviving Corporation ("Advisory Board"),
which shall be comprised of the persons who were directors of the Company
immediately prior to the Effective Time. The Advisory Board shall meet no less
frequently than quarterly and shall provide advice to the board of directors of
the Surviving Corporation with respect to such issues as the board of directors
of the Surviving Corporation may from time to time request, including but not
limited to community relations, customer service, economic development, employee
development and relations and such other matters of community interest as may be
appropriate. The members of the Advisory Board, who shall serve at the
discretion of the Surviving Corporation, shall receive remuneration for their
services equivalent to the remuneration currently provided to non-employee
directors of the Company.

    Section 7.18  TAX-FREE STATUS.  No party shall, nor shall any party permit
any of its subsidiaries to, take any actions which would, or would be reasonably
likely to, adversely affect the status of the Merger as a reorganization within
the meaning of Section 368(a) of the Code, and each party hereto shall use all
reasonable efforts to achieve such result.

                                  ARTICLE VIII
                                   CONDITIONS

    Section 8.1  CONDITIONS TO EACH PARTY'S OBLIGATION TO EFFECT THE
MERGER.  The respective obligations of each party to effect the Merger shall be
subject to the satisfaction on or prior to the Closing Date of the following
conditions, except, to the extent permitted by applicable law, that such
conditions may be waived in writing pursuant to Section 9.5 by the joint action
of the parties hereto:

        (a)  SHAREHOLDER APPROVAL.  The Company Shareholders' Approval shall
have been obtained.

        (b)  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.

        (c)  REGISTRATION STATEMENT.  The Registration Statement shall have
become effective in accordance with the provisions of the Securities Act, and no
stop order suspending such effectiveness shall have been issued and remain in
effect.

the Merger pursuant to Article II shall have been approved for listing on the
NYSE upon official notice of issuance.

                                      A-34
<PAGE>
        (e)  STATUTORY APPROVALS.  The Company Required Statutory Approvals and
the Parent Required Statutory Approvals shall have been obtained at or prior to
the Effective Time, such approvals shall have become Final Orders (as defined
below) and such Final Orders shall not impose terms or conditions which, in the
aggregate, would have, or insofar as reasonably can be foreseen, could have, a
Company Material Adverse Effect or a Parent Material Adverse Effect; provided,
however, that a requirement that Parent become a registered holding company
pursuant to Section 5 of the 1935 Act as a result of the Merger shall not
constitute a term or condition which could have a "material adverse effect"
within the meaning of this Section 8.1(e) of the Agreement. In addition, the
inclusion of a condition or requirement of the Securities and Exchange
Commission's approval of the Merger under the 1935 Act that Parent divest its
ownership of New York State Electric & Gas Corporation, a New York corporation
and wholly owned subsidiary of Parent, shall constitute a term or condition
which could have a "material adverse effect" within the meaning of this Section
8.1(e) of the Agreement. A "Final Order" means action by the relevant regulatory
authority which has not been reversed, stayed, enjoined, set aside, annulled or
suspended, 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.

    Section 8.2  CONDITIONS TO OBLIGATION OF PARENT TO EFFECT THE MERGER.  The
obligation of Parent to effect the Merger shall be further subject to the
satisfaction, on or prior to the Closing Date, of the following conditions,
except as may be waived by Parent in writing pursuant to Section 9.5:

        (a)  PERFORMANCE OF OBLIGATIONS OF THE COMPANY.  The Company (and its
appropriate subsidiaries) shall have performed in all material respects its
agreements and covenants contained in Sections 6.1 and 6.2 and shall have
performed in all material respects its other agreements and covenants contained
in or contemplated by this Agreement to be performed by it at or prior to the
Effective Time.

        (b)  REPRESENTATIONS AND WARRANTIES.  The representations and warranties
of the Company set forth in this Agreement shall be true and correct (i) on and
as of the date hereof and (ii) 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 in
each of cases (i) and (ii) 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 be reasonably
likely to result in a Company Material Adverse Effect.

        (c)  CLOSING CERTIFICATES.  Parent shall have received a certificate
signed by the chief financial officer of the Company, dated the Closing Date, to
the effect that, to the best of such officer's knowledge, the conditions set
forth in Section 8.2(a) and Section 8.2(b) have been satisfied.

        (d)  NO COMPANY MATERIAL ADVERSE EFFECT.  No Company Material Adverse
Effect shall have occurred, and there shall exist no fact or circumstance other
than facts and circumstances described in Section 8.2(d) of the Company
Disclosure Schedule or the Company SEC Reports filed prior to the date hereof
which is reasonably likely to have a Company Material Adverse Effect.

        (e)  COMPANY REQUIRED CONSENTS.  The Company Required Consents the

each of cases (i) and (ii) 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 be reasonably
likely to result in a Parent Material Adverse Effect.

certificate signed by the Executive Vice President and General Counsel of
Parent, dated the Closing Date, to the effect that, to the best of such

of which to obtain would have a Parent Material Adverse Effect shall have been

                       TERMINATION, AMENDMENT AND WAIVER

    Section 9.1  TERMINATION.  This Agreement may be terminated at any time
prior to the Closing Date, 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 any party hereto, by written notice to the other parties, if the
    Effective Time shall not have occurred on or before the date that is 12
    months from the date hereof (the "Initial Termination Date"); provided,
    however, that if on the Initial Termination Date the conditions to the
    Closing set forth in Section 8.1(e) shall not have been fulfilled but all
    other conditions to the Closing shall be fulfilled or shall be capable of
    being fulfilled, then the Initial Termination Date shall be extended to the
    18-month anniversary of the date hereof; and provided, further, that the
    right to terminate this Agreement under this Section 9.1(b) shall not be
    available to any party whose failure to fulfill any obligation under this
    Agreement or whose breach of any agreement or covenant has been the cause
    of, or resulted directly or indirectly in, the failure of the Effective Time
    to occur on or before the Initial Termination Date or as it may be so
    extended.

        (c) by any party hereto, 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 by the Initial
    Termination Date;

        (d) by any party hereto, if any state or federal law, order, rule or
    regulation 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 by any party hereto 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;

        (e) by the Company prior to the time at which the Company Shareholders'
    Approval shall have been obtained, upon five days' prior notice to Parent,
    if the Company is not in breach of this Agreement and, as a result of an
    Alternative Proposal, the Board of Directors of the Company determines in
    good faith, that (i) the Alternative Proposal is financially superior to the
    Merger and the third party making the Alternative Proposal has demonstrated
    that any necessary financing has been obtained, or in the reasonable
    judgment of the Company's financial advisor such financing is obtainable,
    and (ii) after consultation with its financial advisor and based upon the
    advice of outside counsel and such other matters as the Board of Directors
    of the Company deems relevant, after considering applicable provisions of
    state law and after giving effect to all concessions which may be offered by
    the other party pursuant to the proviso below, that failure to do so would
    likely result in a breach of its fiduciary duties under applicable law;
    provided, however, that prior to any such termination, the Company shall,
    and shall cause its respective financial and legal advisors to, negotiate
    with Parent to make such adjustments in the terms and conditions of this
    Agreement as would enable the Company to proceed with the transactions
    contemplated herein;

        (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 or
    would be reasonably likely to result in a Parent Material Adverse Effect,
    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) Parent (or its
    appropriate subsidiaries) shall have failed to perform and comply with, in
    all material respects, its agreements and covenants hereunder, and such
    failure to perform or comply shall not have been remedied within 20 days
    after receipt by

                                      A-37
<PAGE>
    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
    material breaches of the representations and warranties of the Company made
    herein as of the date hereof which breaches, individually or in the
    aggregate, would or would be reasonably likely to result in a Company
    Material Adverse Effect, 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) the Company (or its appropriate subsidiaries) shall not have
    performed and complied with its agreements and covenants contained in
    Sections 6.1(b) and 6.1(c) or shall have failed to perform and comply with,
    in all material respects, its other agreements and covenants hereunder, and
    such failure to perform or comply 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 of the Company or any committee thereof (A)
    shall withdraw or modify in any manner adverse to Parent its approval or
    recommendation of this Agreement or the transactions contemplated herein,
    (B) shall fail to reaffirm such approval or recommendation upon Parent's
    request within two days of such request, (C) shall approve or recommend any
    acquisition of the Company or a material portion of its assets or any tender
    offer for the shares of capital stock of the Company, in each case by a
    party other than Parent or any of its affiliates or (D) shall resolve to
    take any of the actions specified in clause (A), (B) or (C).

    Section 9.2  EFFECT OF TERMINATION.  Subject to Section 10.1(b), in the
event of termination of this Agreement by either the Company or Parent pursuant
to Section 9.1, there shall be no liability on the part of either the Company or
Parent or their respective officers or directors hereunder, except that Section
7.12, Section 9.3, the agreement contained in the last sentence of Section 7.1,
Section 10.8 and Section 10.9 shall survive the termination.

    Section 9.3  TERMINATION FEE; EXPENSES.

        (a)  TERMINATION FEE UPON BREACH OR WITHDRAWAL OF APPROVAL.  If this
Agreement is terminated at such time that this Agreement is terminable pursuant
to one (but not both) of (x) Section 9.1(f)(i) or (ii) or (y) Section 9.1(g)(i)
or (ii), then: (i) the breaching party shall promptly (but not later than five
business days after receipt of notice from the non-breaching party) pay to the
non-breaching party in cash an amount equal to all documented out-of-pocket
expenses and fees incurred by the non-breaching party (including, without
limitation, fees and expenses payable to all legal, accounting, financial,
public relations and other professional advisors arising out of, in connection
with or related to the Merger or the transactions contemplated by this
Agreement) not in excess of $4 million ("Expenses"); provided, however, that, if
this Agreement is terminated by a party as a result of a willful breach by the
other party, the non-breaching party may pursue any remedies available to it at
law or in equity and shall, in addition to its out-of-pocket expenses (which
shall be paid as specified above and shall not be limited to $4 million), be
entitled to retain such additional amounts as such non-breaching party may be
entitled to receive at law or in equity.

        (b) The Company shall pay Parent a fee of $14 million ("Termination
Fee") plus Expenses, upon the termination of this Agreement by Parent or the
Company pursuant to Section 9.1(c) or the Company pursuant to Section 9.1(e) or
by Parent pursuant to Section 9.1(g)(iii); provided, however, that in the event
of termination under either Section 9.1(c) or Section 9.1(g)(iii), no payment of
the Termination Fee or Expenses shall be required unless and until within two
years of such termination the Company enters into a definitive agreement to
consummate or consummates an Alternative Proposal, and, in the case of a
termination pursuant to Section 9.1(c), there shall have been made and not
withdrawn at the time of the Company Special Meeting an Alternative Proposal

        (c)  LIQUIDATED DAMAGES; PROMPT PAYMENT.  The parties agree that the
agreements contained in this Section 9.3 are an integral part of the
transactions contemplated by the Agreement and constitute liquidated damages and
not a penalty. If one party fails to pay promptly to the other any fee or
expenses due hereunder, 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

rate of Chase Manhattan Bank, N.A., from the date such fee was required to be
paid.

Directors of the parties hereto, at any time before or after approval hereof by

approvals, no such amendment shall (a) alter or change the amount or kind of
shares, rights or any of the proceedings of the treatment of shares under
Article II, or (b) alter or change any of the terms and conditions of this
Agreement if any of the alterations or changes, alone or in the aggregate, would
materially adversely affect the rights of holders of Company capital stock,
except for alterations or changes that could otherwise be adopted by the Board
of Directors of the Company, without the further approval of such shareholders.

behalf of each of the parties hereto.

other acts of the other parties hereto, (b) waive any inaccuracies in the

                                                   June 29, 1999

CONFIDENTIAL

Board of Directors
CTG Resources, Inc.
100 Columbus Boulevard
Hartford, CT 06103

Ladies and Gentlemen:

    Energy East Corporation ("Parent"), CTG Resources, Inc. (the "Company"), and
Oak Merger Co., a wholly-owned subsidiary of Parent ("Merger Sub"), propose to
enter into an Agreement and Plan of Merger (the "Agreement") which provides for
the merger of the Company with and into Merger Sub, with Merger Sub as the
surviving corporation (the "Merger"). Capitalized terms used herein without
definition have the meanings assigned to them in the Agreement. At the Effective
Time of the Merger, each issued and outstanding share of common stock, without
par value, of the Company ("Company Common Stock") will be converted into the
right to receive (i) $41.00 in cash (the "Cash Consideration") or (ii) a number
of validly issued, fully paid and nonassessable shares of common stock, par
value $.01 per share, of Parent ("Parent Common Stock") equal to the Exchange
Ratio (as defined below) (the "Stock Consideration") or (iii) the right to
receive a combination of cash and shares of Parent Common Stock determined in
accordance with the Agreement (the "Mixed Consideration"). The "Exchange Ratio"
shall be equal to the Cash Consideration divided by either (i) the Parent Share
Price (as defined below) if the Parent Share Price is equal to or less than
$30.13 and equal to or more than $23.67, (ii) $30.13 if the Parent Share Price
is greater than $30.13, in which case the Exchange Ratio shall equal 1.3609, or
(iii) $23.67 if the Parent Share Price is less than $23.67, in which case the
Exchange Ratio shall equal 1.7320. The "Parent Share Price" shall be equal to
the average of the closing prices of the shares of Parent Common Stock on the
New York Stock Exchange Composite Transactions Reporting System, as reported in
the Wall Street Journal, for the 20 days immediately preceding the second
trading day prior to the Effective Time. The Cash Consideration, the Stock
Consideration and the Mixed Consideration are collectively defined herein as the
"Merger Consideration."

    You have asked us whether or not, in our opinion, the Merger Consideration
is fair, from a financial point of view, to the holders of Company Common Stock.

    In arriving at the opinion set forth below, we have, among other things:

(1) Reviewed the Company's Annual Reports, Forms 10-K and related financial
    information for the five fiscal years ended September 30, 1998 and the
    Company's Form 10-Q and the related unaudited financial information for the
    six months ended March 31, 1999;

    and monetary conditions.

(11) In preparing our opinion, we have relied on the accuracy and completeness
    of all information supplied or otherwise made available to us by the Company
    and Parent, and we have not assumed any responsibility to independently
    verify such information. With respect to the financial forecasts examined by
    us, we have assumed that they were reasonably prepared and reflect the best
    currently available estimates and good faith judgments of the managements of
    the Company and Parent, as to the future performance of the Company and
    Parent, respectively. We have also relied upon assurances of the managements
    of the Company and Parent that they are unaware of any facts that would make
    the information or financial forecasts provided to us incomplete or
    misleading. We have not made any independent evaluation or appraisal of the
    assets or liabilities (contingent or otherwise) of the Company or Parent nor
    have we been furnished with any such evaluations or appraisals. We have also
    assumed with your consent, that (i) the Merger will be accounted for under
    the purchase method of accounting, (ii) the Merger will be a tax free
    reorganization and (iii) any material liabilities (contingent or otherwise,
    known or unknown) of the Company or Parent are as set forth in the
    consolidated financial statements of the Company and Parent, respectively.
    No opinion is expressed herein as to the price at which Company Common Stock
    or Parent Common Stock may trade at any time. Our opinion is based on
    regulatory, general economic, market and monetary conditions existing on the
    date hereof.

(12) This opinion is directed only to the Board of Directors of the Company and
    does not constitute a recommendation to any holder of Company Common Stock
    as to how any such holder should vote on the Merger. This opinion does not
    address the relative merits of the Merger and any other transactions or
    business strategies discussed by the Board of Directors of the Company as
    alternatives to the Merger or the decision of the Board of Directors of the
    Company to proceed with the Merger.

    In the ordinary course of business, PaineWebber Incorporated may trade in
the securities of the Company and Parent for our own account and for the
accounts of our customers and, accordingly, may at any time hold long or short
positions in such securities.

    PaineWebber Incorporated is currently acting as financial advisor to the
Company in connection with the Merger and will be receiving a fee in connection
with the rendering of this opinion and upon consummation of the Merger. In the
past, PaineWebber Incorporated and its affiliates have provided investment

rendering these services.

    On the basis of, and subject to the foregoing, we are of the opinion that
the Merger Consideration is fair, from a financial point of view, to the holders
of Company Common Stock.

action against their shares and all parties must be served with a copy of the
petition. Nonresidents may be served by registered or certified mail or by

    (e) Each dissenter made a party to the proceeding is entitled to judgment
(1) for the amount, if any, by which the court finds the fair value of his
shares, plus interest, exceeds the amount paid by the

                                      C-4
<PAGE>
corporation, or (2) for the fair value, plus accrued interest, of his
after-acquired shares for which the corporation elected to withhold payment
under section 33-867.

    33-872 COURT COSTS AND COUNSEL FEES -- (a) The court in an appraisal
proceeding commenced under section 33-871 shall determine all costs of the
proceeding, including the reasonable compensation and expenses of appraisers
appointed by the court. The court shall assess the costs against the
corporation, except that the court may assess costs against all or some of the
dissenters, in amounts the court finds equitable, to the extent the court finds
the dissenters acted arbitrarily, vexatiously or not in good faith in demanding
payment under section 33-868.

    (b) The court may also assess the fees and expenses of counsel and experts
for the respective parties, in amounts the court finds equitable: (1) Against
the corporation and in favor of any or all dissenters if the court finds the
corporation did not substantially comply with the requirements of sections
33-860 to 33-868, inclusive; or (2) against either the corporation or a
dissenter, in favor of any other party, if the court finds that the party
against whom the fees and expenses are assessed acted arbitrarily, vexatiously
or not in good faith with respect to the rights provided by sections 33-855 to
33-872, inclusive.

    (c) If the court finds that the services of counsel for any dissenter were
of substantial benefit to other dissenters similarly situated, and that the fees
for those services should not be assessed against the corporation, the court may
award to these counsel reasonable fees to be paid out of the amounts awarded the
dissenters who were benefited.

                   INFORMATION NOT REQUIRED IN THE PROSPECTUS

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS

    The Business Corporation Law of the State of New York ("BCL") provides that
if a derivative action is brought against a director or officer, the Registrant
may indemnify him against amounts paid in settlement and reasonable expenses,
including attorneys' fees, incurred by him in connection with the defense or
settlement of such action, if such director or officer acted in good faith for a
purpose which he reasonably believed to be in the best interests of the
Registrant, except that no indemnification shall be made without court approval
in respect of a threatened action, or a pending action settled or otherwise
disposed of, or in respect of any matter as to which such director or officer
has been found liable to the Registrant. In a nonderivative action or threatened
action, the BCL provides that the Registrant may indemnify a director or officer
against judgments, fines, amounts paid in settlement and reasonable expenses,
including attorneys' fees incurred by him in defending such action if such
director or officer acted in good faith for a purpose which he reasonably
believed to be in the best interests of the Registrant.

    Under the BCL, a director or officer who is successful, either in a
derivative or nonderivative action, is entitled to indemnification as outlined
above. Under any other circumstances, such director or officer may be
indemnified only if certain conditions specified in the BCL are met. The
indemnification provisions of the BCL are not exclusive of any other rights to
which a director or officer seeking indemnification may be entitled pursuant to
the provisions of the certificate of incorporation or the by-laws of a
corporation or, whether authorized by such certificate of incorporation or
by-laws, pursuant to a shareholders' resolution, a directors' resolution or an
agreement providing for such indemnification.

    The above is a general summary of certain provisions of the BCL and is
subject, in all cases, to the specific and detailed provisions of Sections
721-725 of the BCL.

    The By-Laws of the Registrant provide that to the extent not prohibited by
law, the Registrant shall indemnify each person made, or threatened to be made,
a party to any civil or criminal action or proceeding by reason of the fact that
he, or his testator or intestate, (i) is or was a director or officer of the
Registrant or (ii) is or was serving any other corporation of any type or kind,
domestic or foreign, or any partnership, joint venture, trust, employee benefit
plan or other enterprise, in any capacity at the request of the Registrant.

    The By-Laws of the Registrant also provide, among other things, that:

    (1) no indemnification shall be made to or on behalf of any director or
officer, if a judgment or other final adjudication adverse to the director or
officer establishes that his acts were committed in bad faith or were the result
of active and deliberate dishonesty and were material to the cause of action so
adjudicated, or that he personally gained in fact a financial profit or other
advantage to which he was not legally entitled;

    (2) the rights to indemnification and advancement of defense expenses
granted by or pursuant to the By-Laws shall not limit or exclude, but shall be
in addition to, any other rights which may be granted by or pursuant to any
statute, certificate of incorporation, by-law, resolution or agreement; and

    (3) the Registrant may, with the approval of the Board of Directors, enter
into an agreement with any person who is, or is about to become, a director or
officer of the Registrant, or who is serving, or is about to serve, at the
request of the Registrant, as a director, officer, or in any other capacity, any
other corporation of any type or kind, domestic or foreign, or any partnership,
joint venture, trust, employee benefit plan or other enterprise, which agreement
may provide for indemnification of such

                                      II-1
<PAGE>
person and advancement of defense expenses to such person upon such terms, and
to the extent, not prohibited by law.

    The Registrant has insurance policies indemnifying its directors and
officers against certain obligations that may be incurred by them, subject to
certain retention and co-insurance provisions.

    See Exhibit Index.

ITEM 22. UNDERTAKINGS

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

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

    (c) The undersigned Registrant hereby undertakes as follows: that prior to
any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this Registration Statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other items of the applicable form.

    (d) The Registrant undertakes that every prospectus: (i) that is filed
pursuant to paragraph (c) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Act and is used in connection with
an offering of securities subject to Rule 415, will be filed as a part of an
amendment to the Registration Statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offering
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

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

                                      II-2

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

    (g) The undersigned Registrant hereby undertakes:

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

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

       (ii) To reflect in the prospectus any facts or events arising after the
           effective date of the Registration Statement (or the most recent
           post-effective amendment thereof) which, individually or in the
           aggregate, represent a fundamental change in the information set
           forth in the Registration Statement. Notwithstanding the foregoing,
           any increase or decrease in volume of securities offered (if the
           total dollar value of securities offered would not exceed that which
           was registered) and any deviation from the low or high end of the
           estimated maximum offering range may be reflected in the form of
           prospectus filed with the Commission pursuant to Rule 424(b) if, in
           the aggregate, the changes in volume and price represent no more than
           20 percent change in the maximum aggregate offering price set forth
           in the "Calculation of Registration Fee" table in the effective
           Registration Statement;

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

PROVIDED, HOWEVER, that paragraphs (g)(1)(i) and (g)(1)(ii) do not apply if the
Registration Statement is on Form S-3, Form S-8 or Form F-3, and the information
required to be included in a post-effective amendment by those paragraphs is
contained in periodic reports filed with or furnished to the Commission by the
Registrant pursuant to Section 13 or 15(d) of the Securities Exchange Act of
1934 that are incorporated by reference in the Registration Statement.

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

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

    (4) If the Registrant is a foreign private issuer, to file a post-effective
       amendment to the Registration Statement to include any financial
       statements required by Rule 3-19 of this chapter at the start of any
       delayed offering or throughout a continuous offering. Financial
       statements and information otherwise required by Section 10(a)(3) of the
       Act need not be furnished, PROVIDED, that the Registrant includes in the
       prospectus, by means of a post-effective amendment, financial statements
       required pursuant to this paragraph (g)(4) and other information
       necessary to ensure that all other information in the prospectus is at
       least as current as the date of those financial statements.
       Notwithstanding the foregoing, with respect to registration statements on
       Form F-3, a post-effective amendment need not be filed to include
       financial statements and information required by Section 10(a)(3) of the
       Act or Rule 3-19 of this chapter if such financial statements and
       information are contained in periodic reports filed with or furnished to
       the Commission by the Registrant pursuant to Section 13 or Section 15(d)
       of the Securities Exchange Act of 1934 that are incorporated by reference
       in the Form F-3.

         Re: REGISTRATION STATEMENT ON FORM S-4

Ladies and Gentlemen:

         We have acted as counsel for Energy East Corporation (the "Company")
in connection with a Registration Statement on Form S-4 (the "Registration
Statement") being filed with the Securities and Exchange Commission for the
purpose of registering under the Securities Act of 1933, as amended, shares
of the Company's Common Stock, with a par value of One Cent ($.01) per share
(the "Common Stock"), to be issued in connection with the merger of CTG
Resources, Inc., a Connecticut corporation, into the Company's wholly owned
subsidiary, Oak Merger Co., a Connecticut corporation (the "Merger") pursuant
to the Agreement and Plan of Merger (the "Merger Agreement") by and among CTG
Resources, Inc., the Company and Oak Merger Co. dated as of June 29, 1999,
filed as Appendix A to the Proxy Statement/Prospectus which forms a part of
the Registration Statement. All capitalized terms not otherwise defined
herein have the same meanings as defined in the Registration Statement.

         As counsel to the Company, we are generally familiar with its corporate
proceedings and have examined the Registration Statement and the Merger
Agreement and such other documents as we have deemed relevant and necessary as a
basis for the opinion hereinafter set forth. In addition, we have made such
other and further investigations as we have deemed relevant and necessary as a
basis for the opinion hereinafter set forth.

         In such examination, we have assumed the genuineness of all signatures,
the legal capacity of natural persons, the authenticity of all documents
submitted to us as originals, the conformity to original documents of all
documents submitted to us as certified or photostatic copies, and the
authenticity of the originals of such latter documents.

         Based on the foregoing and upon such further examination of corporate
records and documents and matters of law as we have considered necessary or
desirable for the purposes of this opinion, it is our opinion that the Common
Stock, when issued in accordance with the terms of the Merger Agreement, will be
validly issued, fully paid and non-assessable shares of Common Stock of the
Company.

         The opinion expressed herein is limited to the laws of the State of New
York and to applicable United States federal law and we express no opinion as to
the laws of any other jurisdiction.

         We hereby consent to the making of the statements with reference to our
firm under the heading "Legal Matters" in the Registration Statement and to the
filing of this opinion as Exhibit 5.1 to the Registration Statement.

                                             Very truly yours,

                  Among CTG Resources, Inc. (the "Company"), Energy East
                  Corporation ("Parent") and Oak Merger Co., a wholly owned
                  subsidiary of Patent ("Merger Sub"), Dated as of June 29, 1999
                  (the "Merger")

Ladies and Gentlemen:

         You have requested our opinion relating to certain federal income tax
consequences arising out of the transactions described in the Merger Agreement.
Capitalized terms used but not defined in this letter have the meaning given
them in the Merger Agreement.

         Our conclusions are based upon the facts and representations set forth
in the Proxy Statement/Prospectus of the Company and Parent (the "Proxy
Statement/Prospectus") included in the Registration Statement of Parent on Form
S-4 and accompanying exhibits to be filed in connection with the Merger (the
"Registration Statement"). We have made no independent investigation with regard
to the facts and representations set forth in the Proxy Statement/Prospectus and
the Registration Statement. In rendering our opinion we have assumed, with your
consent, that the preceding facts or representations are true, complete and
accurate as of the date hereof and will be true, complete and accurate as of the
Effective Time.

         In rendering our opinion, we have considered the applicable provisions
of the Code, Treasury Regulations promulgated thereunder, pertinent judicial
authorities, interpretive rulings of the Internal Revenue Service (the "IRS")
and such other authorities that we have considered relevant. It should be noted
that statutes, regulations, judicial decisions and administrative
interpretations are subject to change at any time and in certain circumstances
with retroactive effect.

         Based upon and subject to the assumptions and limitations described
above, it is our opinion that the statements made under the caption
"SUMMARY--Material Federal Income Tax Consequences" and "THE MERGER--Material
Federal Income Tax Consequences" in the Proxy Statement/Prospectus, to the
extent they constitute matters of law or legal conclusions, are accurate in
all material respects.

         If any fact, representation or assumption described above or contained
in the Merger Agreement, the Proxy Statement/Prospectus or the Registration
Statement is neither true, correct, nor complete, or in the event of a change in
law after the date hereof adversely affecting the

<PAGE>

conclusions reached in this letter, our opinion shall be void and of no force
or effect. You should be aware that although this letter represents our
opinion concerning the matters specifically discussed, it is not binding on
the courts or on any administrative agency, including the IRS, and a court or
agency may act or hold to the contrary. Our opinion is provided to you as a
legal opinion only, and not as a guaranty or warranty, and is limited to the
specific transactions, documents and matters described above. No opinion may
be implied or inferred beyond that which is expressly stated in this letter.

         We hereby consent to the filing of this opinion as an exhibit to
the Registration Statement and to the references to us therein and in the Proxy
Statement/Prospectus. In giving such consent, we do not hereby admit that we are
in the category of persons whose consent is required under Section 7 of the
Securities Act of 1933, as amended. We are furnishing this opinion in
connection with the filing of the Registration Statement with the SEC, and
this opinion is not to be used, circulated, quoted or otherwise referred to
for any other purpose without our express consent.


                                         Very truly yours,

Ladies and Gentlemen:

         Reference is made to the Registration Statement on Form S-4 (the

("ENERGY EAST"), relating to the merger (the "MERGER") of CTG Resources,
Inc., a Connecticut corporation, with and into Oak Merger Co., a Connecticut

XENERGY, and at that time he shall cease serving as its Chief Operating Officer
unless otherwise notified in writing by the Board. During the Term, the
Executive shall also be a member of the Board of Directors of Connecticut Energy
Corporation. The Executive shall devote substantially all his working time and
efforts to the business and affairs of Parent, the Company and their
subsidiaries and affiliates; PROVIDED, HOWEVER, that the Executive may also
serve on the boards of directors or trustees of other non-affiliated companies
and organizations, as long as such service does not substantially interfere with
the performance of his duties hereunder or violate his obligations under Section
10 hereof.

         5.   COMPENSATION AND RELATED MATTERS.

              5.1.      BASE SALARY. The Company shall pay, or cause to be paid,
to the Executive an annual base salary ("Base Salary") during the period of the
Executive's employment hereunder, which shall be at an initial rate of not less
than $425,000 per year. The Base Salary shall be paid in substantially equal
bi-weekly installments, in arrears. During the period of the Executive's
employment hereunder, the Board shall make an annual review of the Executive's
compensation for possible increase, as the Board deems appropriate in its
business judgment (and, as so increased, shall thereafter constitute "Base
Salary" hereunder). The Base Salary in effect from time to time shall not be
decreased during the Term.

         Compensation of the Executive by Base Salary payments shall not be
deemed exclusive and shall not prevent the Executive from participating in any
other compensation or benefit plan of Parent, XENERGY or the Company. The Base
Salary payments (including any increased Base Salary payments) shall not in any
way limit or reduce any other obligation of Parent or the Company hereunder, and
no other compensation, benefit or payment hereunder shall in any way limit or
reduce the obligation of the Company to pay the Executive's Base Salary.

              5.2.      BENEFIT PLANS. The Executive shall be entitled to
participate in or receive benefits under any "employee benefit plan" (as defined
in section 3(3) of the Employee Retirement Income Security Act of 1974, as
amended from time to time ("ERISA")) or employee benefit arrangement made
available by Parent, XENERGY or the Company during the period of the Executive's
employment hereunder to their executives and key management employees, subject
to and on a basis consistent with the terms, conditions and overall
administration of such plans and arrangements. The Executive's participation in
such employee benefit plans and arrangements shall be on an appropriate level,
but no less favorable than the level of other peer executives of Parent, XENERGY
and the Company, as determined by the Board.

              5.3.      INCENTIVE COMPENSATION. The Executive shall be entitled
to participate in or receive benefits under any short or long-term incentive
compensation plan made available by Parent during the period of the Executive's
employment hereunder to their executives and key


                                      -2-

<PAGE>


management employees at a level appropriate for the Executive's position as
determined by the Board, but no less favorable than the level of other peer
executives of Parent, XENERGY and the Company, subject to and on a basis
consistent with the terms, conditions and overall administration of such plans
and arrangements; PROVIDED, HOWEVER, that the Executive shall not be eligible to
receive benefits from any long-term incentive compensation plan, policy or
arrangement of Parent to the extent the Executive is receiving a similar benefit
pursuant to an incentive compensation plan, policy or arrangement of the Company
or any of its subsidiaries.

              5.4.      FRINGE BENEFITS. The Executive shall be entitled to
receive any fringe benefits which are made available by Parent, XENERGY or the
Company during the period of the Executive's employment hereunder to their
executives and key management employees; provided, however, if not otherwise
included, Executive shall receive: (a) an automobile provided at the expense of
the Parent or a subsidiary thereof, (b) payment for luncheon club dues at a
level not less than that which the Executive was entitled to receive immediately
prior to the Effective Time, and (c) financial and tax planning services and
computer allowance of $3,500 per year.

              5.5.      EXPENSES. Upon presentation of reasonably adequate
documentation to Parent, the Executive shall receive prompt reimbursement from
Parent or a subsidiary thereof for all reasonable and customary business
expenses incurred by the Executive in accordance with Parent's policy in
performing services hereunder.

              5.6.      VACATION. The Executive shall be entitled to five (5)
weeks of vacation during each year of this Agreement, or such greater period as
the Board shall approve, without reduction in salary or other benefits.

              5.7.      COMPLETION BONUSES. Parent shall pay, or cause to be
paid, to the Executive in cash a bonus of $400,000 within five (5) days of the
Effective Time. Parent shall pay, or cause to be paid, to the Executive the
following completion bonuses (the "Completion Bonuses") upon completion of the
specified periods of his employment: (i) $400,000 if Executive is employed with
Parent or any subsidiary or affiliate thereof on the one (1) year anniversary of
the Effective Time; and (ii) $400,000 if Executive is employed with Parent or
any subsidiary or affiliate thereof on the two (2) year anniversary of the
Effective Time. Each Completion Bonus shall be paid within five (5) days after
the respective anniversary of the Effective Time.

              5.8.      SPECIAL RETIREMENT BENEFIT. If the Executive retires on
or after his 60th birthday ("Retirement"), or if the Executive's employment
hereunder is terminated within three years after the Effective Time by the
Company without Cause (other than Disability) or by the Executive for Good
Reason ("Wrongful Termination"), or for any reason (including, without
limitation, the Executive's death) thereafter during the Term, the Executive (or
in the event of his death at any time during the Term, his surviving spouse)
shall be entitled to a supplemental retirement benefit (the "Special Retirement
Benefit") as set forth herein, which shall be in addition to his pension
benefits under all qualified and nonqualified defined benefit retirement plans
of the Company and Parent and their affiliates and all of his prior employers
(the "Basic Plans"). The Special Retirement Benefit shall be payable in the form
of a monthly single life


                                      -3-

<PAGE>


annuity, or, if the Executive is married at the commencement of the Special
Retirement Benefit or at the time of his death during the Term, in the form of
an actuarially equivalent joint and 66 2/3% survivor benefit with the surviving
spouse to whom he was married at the time of the commencement of the Special
Retirement Benefit or date of death, if earlier (the amount of which actuarially
equivalent benefit shall be determined based on assumptions no less favorable to
the Executive than the applicable assumptions in the Connecticut National Gas
Corporation Officers' Retirement Plan immediately prior to the Effective Time).
The Special Retirement Benefit shall be payable beginning as of (i) in the case
of the Executive's Retirement, the date of the Executive's Retirement, (ii) in
the case of the Executive's Wrongful Termination, the third anniversary of the
Date of Termination, (iii) in the case of the Executive's death during the Term,
the date of his death, and (iv) in all other cases, the later of the date of the
Executive's termination of employment or the Executive's 60th birthday. The
amount of the Special Retirement Benefit shall be such that for each month, the
aggregate of the monthly payments payable to the Executive pursuant to the
Special Retirement Benefit and the Basic Plans equals 75% of the highest annual
rate of the Executive's Base Salary in effect at any time during the Term,
divided by twelve; provided, that in determining the amounts payable pursuant to
the Basic Plans, it shall be assumed that the benefits thereunder are payable in
the same form as the Special Retirement Benefit, beginning on the earliest date
permitted by the terms of the applicable Basic Plan. If the Executive (or in the
case of the Executive's death during the Term, his surviving spouse) becomes
entitled to receive the Special Retirement Benefit, he or his surviving spouse,
as applicable, shall supply Parent and the Company with such information as they
may reasonably request relating to his benefits from retirement plans of prior
employers in order to determine the amount of the Special Retirement Benefit.

         6.   COMPENSATION RELATED TO DISABILITY. During the Term of this
Agreement, during any period that the Executive fails to perform the Executive's
full-time duties hereunder as a result of incapacity due to physical or mental
illness, Parent shall pay, or cause to be paid, to the Executive his Base Salary
at the rate in effect at the commencement of any such period, together with all
compensation and benefits payable to the Executive under the terms of any
compensation or benefit plan, program or arrangement maintained by Parent,
XENERGY or the Company during such period, until the Executive's employment is
terminated by Parent for Disability; PROVIDED, HOWEVER, that such payments shall
be reduced by the sum of the amounts, if any, payable to the Executive at or
prior to the time of any such payment under disability benefit plans of Parent
or the Company or under the Social Security disability insurance program, which
amounts were not previously applied to reduce any such payment.

         7.   TERMINATION COMPENSATION AND BENEFITS.

              7.1.      If the Executive's employment shall be terminated for
any reason during the Term of this Agreement, the Company shall pay the
Executive's Base Salary (to the Executive or in accordance with Section 11.2 if
the Executive's employment is terminated by his death) through the Date of
Termination at the rate in effect immediately prior to the time the Notice of
Termination is given, together with all compensation and benefits (other than
severance compensation and benefits) payable to the Executive through the Date
of Termination or thereafter under the terms of any compensation or benefit
plan, program or arrangement maintained by Parent, XENERGY or the Company during
such period, and any unreimbursed


                                      -4-

<PAGE>


expenses payable pursuant to Section 5.5 of the Agreement that were incurred
before the Date of Termination.

              7.2.      In the event the Executive's employment is terminated
prior to the expiration of the Term of the Agreement by the Executive for Good
Reason or by Parent or the Company for reasons other than Cause (other than the
death or Disability of the Executive), the Executive shall receive, in addition
to amounts payable under Section 7.1 and 7.3, (i) a lump sum cash payment to be
made within five (5) days of the Date of Termination equal to three times the
sum of the Base Salary and incentive compensation (as described below), (ii)
continuation of the benefits provided for in Section 5.2 of this Agreement for
the remainder of the Term, and (iii) the Special Retirement Benefit (to the
extent provided for in Section 5.8 hereof). For purposes of determining
equivalent value of incentive compensation, the value of short-term incentive
compensation shall be the higher of (i) the amount of short-term compensation
payable to the Executive with respect to the fiscal year ended immediately prior
to the Date of Termination and (ii) the average of the amounts of short-term
compensation payable to the Executive with respect to each of the three most
recently completed fiscal years ended immediately prior to the Date of
Termination, and the value of long-term incentive compensation shall be the
value of long-term incentive compensation awards outstanding on the Date of
Termination for performance periods ending after the Date of Termination, such
value being determined based upon the projected target value of the applicable
long-term incentive compensation award as determined by the Company in
connection with the grant thereof.

              7.3.      If the Executive's employment shall be terminated for
any reason during the Term of this Agreement, the Company shall pay (i) the
Executive's normal post-termination compensation and benefits (other than
severance compensation and benefits) to the Executive as such payments become
due, and (ii) the Special Retirement Benefit as and to the extent provided for
in Section 5.8. Such normal post-termination compensation and benefits (other
than severance compensation and benefits) shall be determined under, and paid in
accordance with, Parent's or the Company's retirement, insurance and other
compensation or benefit plans, programs and arrangements (other than this
Agreement), as applicable.

              7.4.      (a) Anything in this Agreement to the contrary
notwithstanding, in the event it shall be determined that any payment, benefit,
or distribution by Parent, the Company or their affiliates to or for the benefit
of the Executive, whether paid or payable or distributed or distributable
pursuant to the terms of this Agreement or otherwise (a "Payment"), would be
subject to the excise tax imposed by Section 4999 of the Code, or any interest
or penalties with respect to such excise tax (such excise tax, together with any
such interest and penalties, are hereinafter collectively referred to as the
"Excise Tax"), then the Executive shall be entitled to receive an additional
payment ("Gross-Up Payment") in an amount such that after payment by the
Executive of all taxes (including any interest or penalties imposed with respect
to such taxes), including, without limitation, any income taxes and Excise Tax
imposed upon the Gross-Up Payment, the Executive retains an amount of the
Gross-Up Payment equal to the Excise Tax imposed upon the Payments.

                        (b)  Subject to the provisions of Section 7.4(c) hereof,
all determinations required to be made under this Section 7.4, including whether
a Gross-Up


                                      -5-

<PAGE>


Payment is required and the amount of such Gross-Up Payment and the assumptions
to be used in arriving at such determinations, shall be made by Parent's
principal outside accounting firm (the "Accounting Firm") which shall provide
detailed supporting calculations both to the Board and the Executive within
fifteen (15) business days of the Date of Termination and/or such earlier
date(s) as may be requested by Parent or the Executive (each such date and the
Date of Termination shall be referred to as a "Determination Date" for purposes
of this Section 7.4(b) and Section 7.5 hereof). All fees and expenses of the
Accounting Firm shall be borne solely by the Company. The initial Gross-Up
Payment, if any, as determined pursuant to this Section 7.4(b), shall be paid by
the Company to the Executive within five (5) days of the receipt of the
Accounting Firm's determination. If the Accounting Firm determines that no
Excise Tax is payable by the Executive, it shall furnish the Executive with a
written opinion that failure to report the Excise Tax on the Executive's
applicable federal income tax return would not result in the imposition of a
negligence or similar penalty. Any determination by the Accounting Firm under
this Section 7.4(b) shall be binding upon Parent, the Company and the Executive.
As a result of the uncertainty in the application of Section 4999 of the Code at
the time of the initial determination by the Accounting Firm hereunder, it is
possible that Gross-Up Payments which will not have been made by the Company
should have been made ("Underpayment") consistent with the calculations required
to be made hereunder. In the event that Parent exhausts its remedies pursuant to
Section 7.4(c) and the Executive thereafter is required to make a payment of any
Excise Tax, the Accounting Firm shall determine the amount of the Underpayment
that has occurred and any such Underpayment shall be promptly paid by the
Company to or for the benefit of the Executive.

                        (c)  The Executive shall notify Parent in writing of any
claim by the Internal Revenue Service that, if successful, would require the
payment by the Company of an Underpayment. Such notification shall be given as
soon as practicable but no later than ten (10) business days after the Executive
is informed in writing of such claim and shall apprise Parent of the nature of
such claim and the date on which such claim is requested to be paid. The
Executive shall not pay such claim prior to the expiration of the thirty (30)
day period following the date on which he gives such notice to Parent (or such
shorter period ending on the date that any payment of taxes with respect to such
claim is due). If Parent notifies the Executive in writing prior to the
expiration of such period that it desires to contest such claim, the Executive
shall:

                             (i)       give Parent any information reasonably
                                       requested by Parent relating to such
                                       claim;

                             (ii)      take such action in connection with
                                       contesting such claim as Parent shall
                                       reasonably request in writing from time
                                       to time, including, without limitation,
                                       accepting legal representation with
                                       respect to such claim by an attorney
                                       reasonably selected by Parent;

                             (iii)     cooperate with Parent in good faith in
                                       order to effectively contest such claim;
                                       and


                                      -6-

<PAGE>


                             (iv)      permit Parent to participate in any
                                       proceeding relating to such claim;

PROVIDED, HOWEVER, that Parent shall bear and pay directly all costs and
expenses (including additional interest and penalties) incurred in connection
with such contest and shall indemnify and hold the Executive harmless, on an
after-tax basis, for any Excise Tax or income tax, including interest and
penalties with respect thereto, imposed as a result of such representation and
payment of costs and expenses. Without limitation on the foregoing provisions of
this Section 7.4(c), Parent shall control all proceedings taken in connection
with such contest and, at its sole option, may pursue or forgo any and all
administrative appeals, proceedings, hearings and conferences with the taxing
authority in respect of such claim and may, at its sole option, either direct
the Executive to pay the tax claimed and sue for a refund or contest the claim
in any permissible manner, and the Executive agrees to prosecute such contest to
a determination before any administrative tribunal, in a court of initial
jurisdiction and in one or more appellate courts, as Parent shall determine;
PROVIDED, HOWEVER, that if Parent directs the Executive to pay such claim and
sue for a refund, the Company shall advance the amount of such payment to the
Executive on an interest-free basis and shall indemnify and hold the Executive
harmless, on an after-tax basis, from any Excise Tax or income tax, including
interest or penalties with respect thereto, imposed with respect to such advance
or with respect to any imputed income with respect to such advance; and
PROVIDED, FURTHER that any extension of the statute of limitations relating to
payment of taxes for the taxable year of the Executive with respect to which
such contested amount is claimed to be due is limited solely to such contested
amount. Furthermore, Parent's control of the contest shall be limited to issues
with respect to which a Gross-Up Payment would be payable hereunder and the
Executive shall be entitled to settle or contest, as the case may be, any other
issue raised by the Internal Revenue Service or any other taxing authority.

                        (d)  If, after the receipt by the Executive of an amount
advanced by the Company pursuant to Section 7.4(c) hereof, the Executive becomes
entitled to receive any refund with respect to such claim, the Executive shall
(subject to Parent's and the Company's complying with the requirements of
Section 7.4(c) hereof) promptly pay to the Company the amount of such refund
(together with any interest paid or credited thereon after taxes applicable
thereto). If, after the receipt by the Executive of an amount advanced by the
Company pursuant to Section 7.4(c) hereof, a determination is made that the
Executive shall not be entitled to any refund with respect to such claim and
Parent does not notify the Executive in writing of its intent to contest such
denial of refund prior to the expiration of thirty (30) days after such
determination, then such advance shall be forgiven and shall not be required to
be repaid.

              7.5.      The payments provided for in Section 7.4 hereof (other
than Section 7.4(c) and (d)) shall be made not later than the fifth (5th) day
following each Determination Date; PROVIDED, HOWEVER, that if the amounts of
such payments cannot be finally determined on or before such day, the Company
shall pay to the Executive on such day an estimate, as determined by the
Executive, of the minimum amount of such payments to which the Executive is
clearly entitled and shall pay the remainder of such payments (together with
interest at the rate provided in Section 1274(b)(2)(B) of the Code) as soon as
the amount thereof can be determined but in no event later than the thirtieth
(30th) day after each Determination Date. In the event that the


                                      -7-

<PAGE>


amount of the estimated payments exceeds the amount subsequently determined to
have been due, such excess shall constitute a loan by the Company to the
Executive, payable on the fifth (5th) business day after demand by the Company
(together with interest at the rate provided in Section 1274(b)(2)(B) of the
Code).

              7.6.      The Company also shall pay to the Executive all
reasonable legal fees and expenses incurred by the Executive as a result of a
termination which entitles the Executive to the Severance Payments (including
all such fees and expenses, if any, incurred in disputing any termination or in
seeking in good faith to obtain or enforce any benefit or right provided by this
Agreement or in connection with any tax audit or proceeding to the extent
attributable to the application of Section 4999 of the Code to any payment or
benefit provided hereunder); PROVIDED, HOWEVER, the Company shall not be
required to pay to the Executive legal fees and expenses to the extent such
legal fees and expenses were incurred in connection with a contest controlled by
Parent pursuant to Section 7.4(c) hereof in connection with which Parent
complied with its obligations under said Section 7.4(d). Such payments shall be
made within five (5) business days after delivery of the Executive's written
request for payment accompanied with such evidence of fees and expenses incurred
as Parent reasonably may require.

        8.    TERMINATION PROCEDURES.

              8.1.      NOTICE OF TERMINATION. During the Term of this
Agreement, any purported termination of the Executive's employment (other than
by reason of death) shall be communicated by written Notice of Termination from
one party hereto to the other party hereto in accordance with Section 12 hereof.
For purposes of this Agreement, a "Notice of Termination" shall mean a notice
which shall indicate the specific termination provision in this Agreement relied
upon and, in the case of a termination by the Company for Cause or by the
Executive for Good Reason, shall set forth in reasonable detail the facts and
circumstances claimed to provide a basis for termination of the Executive's
employment under the provision so indicated. Further, a Notice of Termination
for Cause is required to include a copy of a resolution duly adopted by the
affirmative vote of not less than three-quarters (3/4) of the entire membership
of the Board at a meeting of the Board which was called and held for the purpose
of considering such termination (after reasonable notice to the Executive and an
opportunity for the Executive, together with the Executive's counsel, to be
heard before the Board) finding that, in the good faith opinion of the Board,
the Executive was guilty of conduct set forth in clause (i) or (ii) of the
definition of Cause herein, and specifying the particulars thereof in detail.

              8.2.      DATE OF TERMINATION. "Date of Termination", with respect
to any purported termination of the Executive's employment during the Term of
this Agreement, shall mean (i) if the Executive's employment is terminated by
his death, the date of his death, (ii) if the Executive's employment is
terminated for Disability, thirty (30) days after Notice of Termination is
given (provided that the Executive shall not have returned to the full time
performance of the Executive's duties during such thirty (30) day period),
and (iii) if the Executive's employment is terminated for any other reason,
the date specified in the Notice of Termination (which, in the case of a
termination by Parent, shall not be less than thirty (30) days (except in the
case of a termination for Cause) and, in the case of a termination by the
Executive, shall not be less than

                                      -8-

<PAGE>


fifteen (15) days nor more than sixty (60) days, respectively, from the date
such Notice of Termination is given).

         9.   NO MITIGATION. Parent and the Company agree that, if the
Executive's employment hereunder is terminated during the Term, the Executive is
not required to seek other employment or to attempt in any way to reduce any
amounts payable to the Executive by Parent or the Company hereunder. Further,
the amount of any payment or benefit provided for hereunder (other than pursuant
to Section 7.4(d) hereof) shall not be reduced by any compensation earned by the
Executive as the result of employment by another employer, by retirement
benefits, by offset against any amount claimed to be owed by the Executive to
Parent or the Company, or otherwise.

         10.  CONFIDENTIALITY AND NONCOMPETITION.

              10.1.     The Executive will not, during or after the Term,
without the prior written consent of the Parent or as may otherwise be required
by law or legal process, disclose to any entity or person any information which
is treated as confidential by Parent or the Company or any of their subsidiaries
or affiliates (each, an "EE Entity"), and not generally known or available in
the marketplace, and to which the Executive gains access by reason of his
position as an employee or director of any EE Entity.

              10.2.     Except as permitted by Parent or the Company upon its
prior written consent, the Executive shall not, during the Executive's
employment with the EE Entities and for the period ending one year after the
Executive's employment with the EE Entities terminates for any reason enter,
directly or indirectly, into the employ of or render or engage in, directly or
indirectly, any services to any person, firm or corporation within the
"Restricted Territory," which is a major competitor of any EE Entity with
respect to products which any EE Entity is then producing or services which any
EE Entity is then providing (a "Competitor"). However, it shall not be a
violation of the immediately preceding sentence for the Executive to be employed
by, or render services to, a Competitor, if the Executive renders those services
only in lines of business of the Competitor which are not directly competitive
with a primary line of business of any EE Entity or are outside of the
Restricted Territory. For purposes of this Section 10.2, the "Restricted
Territory" shall be the states and/or commonwealths of Connecticut, Vermont,
Massachusetts, New Hampshire, Maine and Rhode Island.

         11.  SUCCESSORS; BINDING AGREEMENT.

              11.1.     In addition to any obligations imposed by law upon any
successor to Parent or the Company, Parent and the Company will require any
successor (whether direct or indirect, by purchase, merger, consolidation or
otherwise) to all or substantially all of the business and/or assets of Parent
or the Company, as the case may be, to expressly assume and agree to perform
this Agreement in the same manner and to the same extent that Parent and the
Company would be required to perform it if no such succession had taken place.
Failure of Parent or the Company to obtain such assumption and agreement prior
to the effectiveness of any such succession shall be a breach of this Agreement
and shall entitle the Executive to compensation from Parent or the Company in
the same amount and on the same terms as the Executive would be entitled to
hereunder if the Executive were to terminate the Executive's


                                      -9-

<PAGE>


employment for Good Reason, except that, for purposes of implementing the
foregoing, the date on which any such succession becomes effective shall be
deemed the Date of Termination.

              11.2.     This Agreement shall inure to the benefit of and be
enforceable by the Executive's personal or legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees. If the
Executive shall die while any amount would still be payable to the Executive
hereunder (other than amounts which, by their terms, terminate upon the death of
the Executive) if the Executive had continued to live, all such amounts, unless
otherwise provided herein, shall be paid in accordance with the terms of this
Agreement to the executors, personal representatives or administrators of the
Executive's estate.

              11.3.     Except as provided herein, at the Effective Time, the
Prior Agreement shall be terminated and no longer in effect; and the Executive

provision of this Agreement to be performed by such other party shall be deemed

prior or subsequent time. No agreements or representations, oral or otherwise,
express or implied, with respect to the subject matter hereof have been made by
any party which are not expressly set forth in this Agreement. This Agreement

successors, heirs, distributees, devisees or legatees for all payment
obligations under this Agreement.

for benefits under this Agreement shall be directed to and initially determined

of this Agreement relied upon. The Board shall afford a reasonable opportunity
to the Executive for a review of the decision denying a claim and shall further
allow the Executive to appeal to the Board a decision of the Board within sixty
(60) days after notification by the Board that the Executive's claim has been
denied. To the extent permitted by applicable law, any further dispute or
controversy arising under or in connection with this Agreement shall be settled
exclusively by arbitration in New York, New York in accordance with the
Commercial Arbitration Rules of the American Arbitration Association then in
effect. Judgment may be entered on the arbitrator's award in any court having

                             (i)       the assignment to the Executive of any
                                       duties inconsistent with the Executive's
                                       status as an executive officer of the
                                       Company and XENERGY or a substantial
                                       alteration in the nature or status of the
                                       Executive's responsibilities consistent

                                       not within the 25-mile radius of
                                       Hartford, Connecticut or Parent or the
                                       Company's requiring the Executive to be
                                       based anywhere other than the Company's
                                       principal executive offices except for
                                       required travel on the business of Parent
                                       or the Company or its affiliates; or

                             (iv)      any purported termination of the
                                       Executive's employment which is not
                                       effected pursuant to a Notice of
                                       Termination satisfying the requirements
                                       of Section 8.1; for purposes of this
                                       Agreement, no such purported termination
                                       shall be effective.

         The Executive's right to terminate the Executive's employment for Good
Reason shall not be affected by the Executive's incapacity due to physical or
mental illness. The Executive's continued employment shall not constitute
consent to, or a waiver of rights with respect to, any act or failure to act
constituting Good Reason hereunder.

                        (k)  "Gross-Up Payment" shall have the meaning stated in
