                  MERGER PROPOSED--YOUR VOTE IS VERY IMPORTANT

Dear Shareholders:

    The Board of Directors of Consolidated Edison, Inc. and the Board of
Trustees of Northeast Utilities have approved a merger that will create a new
holding company, New Con Edison, to hold what today are their independent
businesses. The Boards of both companies believe that the combined entity will
have the size, resources and large customer base that will be critical to
achieving competitive investor returns in the future.

    Upon completion of the merger, New Con Edison will own all of the assets of
Con Edison and Northeast will be a wholly owned subsidiary of New Con Edison.

    If the merger is completed, Con Edison shareholders will receive one share
of New Con Edison common stock for each Con Edison common share.

    Northeast shareholders will receive payment for each Northeast common share,
calculated from a base amount of $25.00 for each Northeast common share, in
either cash or New Con Edison common stock, depending on their election and upon
allocation and proration procedures specified in the merger agreement. As more
fully described in the joint proxy statement/prospectus, that base amount will
be adjusted upward by $1.00 per share if Northeast enters into agreements, on or
prior to December 31, 2000, to sell its interests in the Millstone nuclear
station and $.0034 per share per day for every day after August 5, 2000 through
the day prior to the closing of the merger. As is also more fully described in
the joint proxy statement/prospectus, the value of any stock consideration to be
received by Northeast shareholders may be less than or greater than $25.00
depending upon Con Edison's share price. See "Summary--General--What You Will
Receive in the Merger--Northeast Shareholders" and "Risk Factors--Fluctuation in
Trading Price of Con Edison Common Shares Could Result in Stock Consideration
That May Be Less Than or Greater Than $25.00."

    Each of us will hold a special meeting of our shareholders to consider and
vote on this proposal. Whether or not you plan to attend your company's special
meeting, please take the time to vote by following the instructions on your
proxy card.

    The places, dates and times of the special meetings are as follows:

                     QUESTIONS AND ANSWERS ABOUT THE MERGER

Q: WHEN AND WHERE ARE THE SHAREHOLDERS MEETINGS?

A: The Con Edison shareholders meeting will take place on April 14, 2000, in New
    York, New York. The Northeast shareholders meeting will take place on
    April 14, 2000, in Hartford, Connecticut. The addresses of the meetings are
    listed on pages 22 and 24, respectively.

Q: WHAT WILL HAPPEN IN THE PROPOSED TRANSACTION?

A: As a result of the merger, Con Edison will merge with and into New Con
    Edison, with New Con Edison surviving the merger. An indirect wholly owned
    subsidiary of Con Edison will merge with and into Northeast with Northeast
    surviving the merger and becoming a direct wholly owned subsidiary of New
    Con Edison.

Q: WHAT WILL I RECEIVE FOR MY SHARES?

A: As a result of the merger, each Con Edison shareholder will receive one share
    of New Con Edison common stock for each Con Edison common share that he or
    she holds.

    Northeast shareholders will receive payment for each Northeast common share,
    calculated from a base amount of $25.00, in either cash or New Con Edison
    common stock, depending on their election and upon allocation and proration
    procedures specified in the merger agreement. "Summary--General--What You
    Will Receive in the Merger--Northeast Shareholders."

Q: HOW AND WHEN CAN I MAKE MY ELECTION?

A: Shortly before the merger, written instructions will be sent to Northeast
    shareholders for making their elections for cash or New Con Edison common
    stock.

Q: WILL NORTHEAST SHAREHOLDERS RECEIVE THE SPECIFIC AMOUNT OF CASH AND STOCK
    THAT THEY ELECT TO RECEIVE?

A: Not necessarily. Elections for stock consideration or cash consideration will
    each be subject to allocation and proration procedures. See "The Merger
    Agreement--Allocation and Proration."

Q: WHAT HAPPENS TO MY FUTURE DIVIDENDS?

A: Con Edison and Northeast do not anticipate making any changes to their
    dividend policies prior to the consummation of the merger; however, the Con
    Edison and Northeast Boards will continue to evaluate their respective
    dividend policies in light of business, financial and regulatory
    considerations. The most recent quarterly dividend declared by Con Edison
    was $.545 per share payable on March 15, 2000. The most recent quarterly
    dividend declared by Northeast was $.100 per share payable on March 31,
    2000.

    We expect that, after the merger, New Con Edison will continue the existing
    dividend policy of Con Edison at the time of the merger. The payment of
    dividends by New Con Edison, however, will be subject to approval and
    declaration by the New Con Edison Board of Directors, and will depend on a
    variety of factors, including business, financial and regulatory
    considerations.

Q: WHAT ARE MY FEDERAL TAX CONSEQUENCES AS A RESULT OF THE MERGER?

A: The merger will be tax-free to holders of Con Edison common shares and
    Northeast common shares for U.S. federal income tax purposes, except for
    cash (or certain contingent rights to receive an additional $1.00 of cash
    related to the divestiture condition) received in exchange for Northeast
    common shares.

Q: WHAT DO I NEED TO DO NOW?

A: After carefully reading and considering the information contained in this
    joint proxy statement/ prospectus, please complete and sign your proxy and
    return it in the enclosed postage-paid envelope as soon as possible so that
    your shares may be represented at your special meeting. Con Edison
    shareholders also have the option to vote by telephone or computer. If
    voting by telephone

                                       1
<PAGE>
    or computer, dial the toll-free number or access the Internet address
    indicated on your proxy. You will be prompted to enter the control number
    printed on your proxy and to follow the subsequent simple directions that
    will be provided.

    If you sign, date and send your proxy and do not indicate how you want to
    vote, we will count your proxy as a vote for the approval of the proposals.

Q: WHAT DO I DO IF I WANT TO CHANGE MY VOTE?

A: Send a later-dated, signed proxy card to your company's Secretary, submit a
    later vote by telephone or computer as described above (if you are a Con
    Edison shareholder), or attend your meeting in person and vote. You may also
    revoke your proxy card by sending a notice of revocation to your company's
    Secretary at the address under "The Summary--The Companies" on page 11. You
    may change your vote by using any one of these methods regardless of the
    procedure used to cast your previous vote.

Q: IF MY BROKER HOLDS MY SHARES IN "STREET NAME," WILL MY BROKER VOTE MY SHARES?

A: If you do not provide your broker with instructions on how to vote your
    "street name" shares, your broker will not be permitted to vote them on the
    merger proposals. You should therefore be sure to provide your broker with
    instructions on how to vote your shares. Shareholders should check the
    voting form used by their brokers to see if they offer telephone or computer
    voting.

    If you do not give voting instructions to your broker, you will not be
    counted as voting for purposes of the merger vote unless you appear and vote
    in person at your special meeting. If your broker holds your shares and you
    attend the meeting, please bring a letter from your broker identifying you
    as the beneficial owner of the shares and authorizing you to vote.

Q: WHAT WILL HAPPEN IF I ABSTAIN FROM VOTING OR FAIL TO VOTE?

A: An abstention or failure to vote will have the same effect as a vote against
    the proposals.

Q: SHOULD I SEND IN MY SHARE CERTIFICATES NOW?

A: No. If the merger is completed, we will send Northeast shareholders written
    instructions for exchanging their share certificates. Con Edison
    shareholders will not be required to exchange their Con Edison share
    certificates as a result of the merger.

Q: WHAT VOTE IS REQUIRED TO APPROVE AND ADOPT THE MERGER AND THE TRUST AGREEMENT
    AMENDMENTS?

A: For Con Edison shareholders, the affirmative vote of at least a majority of
    the shares outstanding and entitled to vote as of the Con Edison record date
    is required to approve and adopt the merger agreement.

    For Northeast shareholders, the affirmative vote of at least two-thirds of
    the shares outstanding and entitled to vote as of the Northeast record date
    is required to approve the trust agreement amendments. In order to complete
    the merger, the trust agreement amendments must be approved and at least
    two-thirds of the Northeast shares outstanding and entitled to vote as of
    the Northeast record date must approve the merger.

Q: WHO ELSE MUST APPROVE THE MERGER?

A: In addition to the approval of the Con Edison and Northeast shareholders, the
    merger agreement requires that the parties obtain the approval of state and
    federal regulatory agencies before the merger can be completed. See
    "Regulatory Matters."

Q: WHEN DO YOU EXPECT TO COMPLETE THE MERGER?

A: We are working as quickly as possible and expect to complete the merger
    within 5 to 14 months from the date of this joint proxy
    statement/prospectus.

                                       2
<PAGE>
Q: DO I HAVE DISSENTERS' OR APPRAISAL RIGHTS?

A: No. Neither the holders of Con Edison common shares nor the holders of
    Northeast common shares will have dissenters' or appraisal rights under New
    York or Massachusetts law as a result of the merger.

Q: WHO CAN HELP ANSWER MY QUESTIONS?

A: If you have any questions about the merger or if you need additional copies
    of this joint proxy statement/prospectus or the enclosed proxy card, you

Q: WHERE CAN I FIND MORE INFORMATION ABOUT THE COMPANIES?

A: You can find more information about Con Edison and Northeast from various
    sources described under "Where You Can Find More Information" on page 117 of
    this joint proxy statement/ prospectus.

Q: HOW IMPORTANT IS MY VOTE?

A: SINCE THE MERGER AGREEMENT CANNOT BE CONSUMMATED WITHOUT THE AFFIRMATIVE VOTE
    OF A MAJORITY OF THE CON EDISON SHAREHOLDERS, AND SINCE THE MERGER AGREEMENT
    AND THE TRUST AGREEMENT AMENDMENTS CANNOT BE CONSUMMATED WITHOUT THE
    AFFIRMATIVE VOTE OF TWO-THIRDS OF THE NORTHEAST SHAREHOLDERS, EVERY
    SHAREHOLDER VOTE IS IMPORTANT. AN ABSTENTION OR FAILURE TO VOTE WILL HAVE
    THE SAME EFFECT AS A VOTE AGAINST THE PROPOSALS.

IMPORTANT TO YOU. TO UNDERSTAND THE MERGER FULLY AND FOR A MORE COMPLETE
DESCRIPTION OF THE LEGAL TERMS OF THE MERGER, YOU SHOULD READ CAREFULLY THIS
ENTIRE JOINT PROXY STATEMENT/PROSPECTUS AND THE OTHER DOCUMENTS TO WHICH WE HAVE
REFERRED YOU. SEE "WHERE YOU CAN FIND MORE INFORMATION" ON PAGE 117. WE HAVE

DESCRIPTION OF THE TOPICS PRESENTED IN THIS SUMMARY.

                                    GENERAL

WHAT YOU WILL RECEIVE IN THE MERGER

    CON EDISON SHAREHOLDERS (PAGE 79)

    In the merger, each Con Edison common share will automatically be converted
into one share of New Con Edison common stock. CON EDISON SHAREHOLDERS WILL NOT
BE REQUIRED TO EXCHANGE THEIR CON EDISON SHARE CERTIFICATES AS A RESULT OF THE
MERGER. ACCORDINGLY, CON EDISON SHAREHOLDERS SHOULD NOT SEND IN THEIR CON EDISON
SHARE CERTIFICATES.

    NORTHEAST SHAREHOLDERS (PAGE 79)

    In the merger, Northeast shareholders may elect to receive, for each
Northeast common share, a fraction of a share of New Con Edison common stock
equal to a numerator of $25.00 divided by the weighted average trading price of
Con Edison common shares over 20 trading days randomly selected from the 40
trading days ending five trading days prior to the closing of the merger.
However, the Con Edison share price used to calculate the fraction will not be
less than $36.00 nor greater than $46.00. Also, $1.00 will be added to the
numerator if, on or prior to the closing of the merger, Northeast's subsidiaries
enter into binding agreements to sell their interests in the Millstone nuclear
station. The sale agreements must be approved or recommended for approval by the
Connecticut utility regulatory agency (the "divestiture condition"). In
addition, $.0034 will be added to the numerator for each day after August 5,
2000 through the day prior to the closing of the merger.

    In the alternative, holders of Northeast common shares may elect to receive,
for each Northeast common share, cash consideration equal to $25.00 per
Northeast common share. An additional $1.00 per share will be payable if, on or
prior to the closing of the merger, Northeast satisfies the divestiture
condition and an additional $.0034 per share will be payable for every day after
August 5, 2000 through the day prior to the closing of the merger.

    If the merger closes on or prior to December 31, 2000, and the divestiture
condition has not been satisfied but thereafter and on or prior to December 31,
2000, Northeast satisfies the divestiture condition, then each Northeast
shareholder (whether the shareholder elected stock or cash consideration) will
be entitled to $1.00 per converted Northeast common share to be paid in cash by
New Con Edison. For example, if the merger closed on October 15, 2000 prior to
the satisfaction of the divestiture condition and thereafter on December 15,
2000 the divestiture condition was satisfied, the Northeast shareholders would
be entitled to the additional consideration. In no event where the merger closes
on or prior to December 31, 2000 will Northeast shareholders be entitled to this
additional consideration if the divestiture condition has not been satisfied on
or prior to December 31, 2000. The additional consideration will be paid where
the merger closes after December 31, 2000, and the divestiture condition is
satisfied prior to the closing.

    Elections for stock consideration or cash consideration will each be subject
to allocation and proration procedures. Pursuant to the allocation and proration
procedures, 50% of the Northeast shares eligible to receive the merger
consideration will be converted into the right to receive the cash consideration
and the remaining shares will be converted into New Con Edison common stock.

                                       4
<PAGE>
    Regardless of their election, Northeast shareholders will not necessarily
know the value of their merger consideration at the time of election because
whether the divestiture condition has been satisfied might not be known and the
timing of closing will not be known. Moreover, for those shareholders electing
stock consideration, the exchange ratio for the New Con Edison common stock will
not have been determined and, once determined, the value of New Con Edison
common stock will remain subject to fluctuation. See "Risk Factors--Fluctuations
in Trading Price of Con Edison Common Shares Could Result in Stock Consideration
That May Be Less Than or Greater Than $25.00."

    The election forms that are mailed to Northeast shareholders will provide an
update of the status of the divestiture condition and repeat for shareholders
the manner in which the merger consideration is calculated. NORTHEAST
SHAREHOLDERS SHOULD NOT SEND IN THEIR NORTHEAST SHARE CERTIFICATES UNTIL
INSTRUCTED TO DO SO.

    Also, as noted above, if the merger closes on or prior to December 31, 2000,
and the divestiture condition has not been satisfied but thereafter and on or
prior to December 31, 2000, Northeast satisfies the divestiture condition, then
each Northeast shareholder (whether the shareholder elected stock or cash
consideration) will be entitled to $1.00 per converted Northeast share to be
paid in cash by New Con Edison.

INTERESTS OF CON EDISON'S DIRECTORS AND MANAGEMENT IN THE MERGER (PAGE 61)

    Shareholders should note that some Con Edison directors and officers have
interests in the merger as directors or officers that are different from, or in
addition to, the interests of other Con Edison shareholders. As provided in the
merger agreement, at the completion of the merger, New Con Edison's Board of
Directors will include four members recommended by Northeast and reasonably
acceptable to Con Edison. The remaining New Con Edison directors will be
designated by Con Edison. The merger agreement also provides that the officers
of Con Edison will be the officers of New Con Edison, except with respect to the
President of New Con Edison.

INTERESTS OF NORTHEAST'S TRUSTEES AND MANAGEMENT IN THE MERGER (PAGE 62)

    Shareholders should note that some Northeast trustees and officers have
interests in the merger as trustees or officers that are different from, or in
addition to, the interests of other Northeast shareholders. If Con Edison and
Northeast complete the merger, four Northeast designees, reasonably acceptable
to Con Edison, will become members of the Board of Directors of New Con Edison
and Michael G. Morris will become President of New Con Edison. Eugene R.
McGrath, currently the Chairman, President and Chief Executive Officer of Con
Edison, will continue as the Chairman and Chief Executive Officer of New Con
Edison.

    In addition, each executive officer of Northeast has entered into an
employment agreement with Northeast and has rights under benefit and
compensation plans maintained by Northeast. These agreements and plans will
provide these officers with severance and other benefits if their employment
with New Con Edison is terminated under circumstances set forth in the
employment agreements after the merger and other rights in connection with the
merger.

                              THE MERGER (PAGE 79)

    THE MERGER AGREEMENT IS ATTACHED AS ANNEX A TO THIS JOINT PROXY
STATEMENT/PROSPECTUS. WE ENCOURAGE YOU TO READ THE MERGER AGREEMENT. IT IS THE
PRINCIPAL DOCUMENT GOVERNING THE MERGER.

CONDITIONS TO THE COMPLETION OF THE MERGER (PAGE 83)

    The completion of the merger depends upon meeting a number of conditions,
including the following:

    - approval by the Con Edison and Northeast shareholders, and

    - absence of any legal prohibition on completion of the merger.

    In addition, Con Edison's obligation to complete the merger is subject to,
among other things:

    - accuracy as of closing of the representations and warranties made by
      Northeast, to the extent set forth in the merger agreement,

    - receipt of an opinion of counsel that the Con Edison merger will qualify
      as a tax-free reorganization,

    - absence of a material adverse change with respect to Northeast, and

    - all regulatory approvals being obtained on terms that would not have,
      individually or in the aggregate, a material adverse effect on Con Edison,
      Northeast or New Con Edison and its prospective subsidiaries, taken as a
      whole.

    In addition, Northeast's obligation to complete the merger is subject to,
among other things:

    - accuracy as of closing of the representations and warranties made by Con
      Edison, to the extent set forth in the merger agreement,

    - receipt of a tax opinion of counsel,

    - absence of a material adverse change with respect to Con Edison, and

    - all regulatory approvals being obtained on terms that are not reasonably
      expected to result in a material adverse effect on Con Edison or New Con
      Edison and its prospective subsidiaries, taken as a whole.

<PAGE>
TERMINATION OF THE MERGER AGREEMENT (PAGE 85)

    The merger agreement may be terminated at any time prior to the completion
of the merger:

    (1) by mutual written consent of Con Edison and Northeast,

    (2) by either Con Edison or Northeast if:

       (a) the merger has not been completed by April 13, 2001--however, that
           date becomes October 13, 2001 if the closing of the merger is delayed
           only because there are legal prohibitions to the closing or because
           regulatory approvals have not been received,

       (b) Con Edison or Northeast shareholders do not give the required
           approvals,

       (c) there is a permanent legal prohibition to the merger, or

       (d) the other party breaches the merger agreement such that there would
           be a failure of a closing condition and such breach is either
           incurable or is not cured,

    (3) by Con Edison, if Northeast or any of its trustees or officers breaches
       the non-solicitation provisions of the merger agreement, or

    (4) by Northeast, if prior to obtaining its shareholder approval of the
       merger agreement, Northeast gives notice to Con Edison of the existence
       of a superior proposal, pays the termination fee described below and
       enters into an agreement in connection with the superior proposal.

    Under the merger agreement, neither Con Edison nor Northeast may terminate
the merger agreement based solely on fluctuation in the price of the other
party's shares.

TERMINATION FEES; REIMBURSEMENT OF EXPENSES (PAGE 86)

    TERMINATION FEES

    Northeast must pay to Con Edison a termination fee of $110 million if any of
the following occurs:

    (1) a takeover proposal has been made with respect to Northeast and the
       merger agreement is terminated by Con Edison or Northeast pursuant to
       paragraph (2)(a) under "--Termination of the Merger Agreement" (the
       section allowing a party to terminate if the merger has not been
       completed by a certain date) or Con Edison terminates the merger
       agreement pursuant to paragraph (3) under "--Termination of the Merger
       Agreement" (the section allowing Con Edison to terminate upon a breach by
       Northeast of the non-solicitation provisions),

    (2) a takeover proposal has been made with respect to Northeast and the
       merger agreement is terminated by either Northeast or Con Edison pursuant
       to paragraph (2)(b) under "--Termination of the Merger Agreement" (the
       section allowing a party to terminate in the absence of approval by the
       other party's shareholders), or

    (3) the merger agreement is terminated by Northeast pursuant to
       paragraph (4) under "--Termination of the Merger Agreement" (the section
       allowing Northeast to terminate in the event of a superior proposal).

    However, no termination fee will be payable to Con Edison pursuant to
clause (1) or (2) unless and until Northeast or any Northeast subsidiary has
entered into an acquisition agreement or consummated a takeover proposal within
24 months of the termination.

    REIMBURSEMENT OF EXPENSES (PAGE 87)

    NORTHEAST

    Northeast must pay to Con Edison an expense reimbursement fee of
$20 million in connection with the merger agreement, if any of the following
occur:

    - Con Edison or Northeast terminates the merger agreement pursuant to
      paragraph (2)(b) under "--Termination of the Merger Agreement" (the
      section allowing a party to terminate in the absence of approval by the
      other party's shareholders),

    - Northeast terminates the merger agreement pursuant to paragraph (4) under
      "--Termination of the Merger Agreement" (the section allowing Northeast to
      terminate in the event of a superior proposal), or

    - Con Edison terminates the merger agreement pursuant to paragraph (2)(d)
    under
     "--Termination of the Merger Agreement" (the section allowing a party to
    terminate upon a breach by the other party that would result in a failure of
    a closing condition) or (3) under "--Termination of the Merger Agreement"
    (the section allowing Con Edison to terminate upon a breach by Northeast of
    the non-solicitation provisions).

    CON EDISON

    Con Edison must pay to Northeast an expense reimbursement fee of
$20 million in connection with the merger agreement, if any of the following
occurs:

    - Northeast terminates the merger agreement pursuant to paragraph (2)(b)
      under "--Termination of the Merger Agreement," due to the failure of the
      Con Edison shareholders to approve the merger agreement, or

    - Northeast terminates the merger agreement pursuant to paragraph (2)(d)
      under "--Termination of the Merger Agreement."

REGULATORY APPROVALS (PAGE 75)

    In order to complete the merger, Con Edison and Northeast must receive
approvals from and/or make filings with various federal and state regulatory
agencies. At the federal level, these approvals include approval of the
Securities and Exchange Commission, the Nuclear Regulatory Commission and the
Federal Energy Regulatory Commission. In addition, the waiting period under the
Hart-Scott-Rodino Antitrust Improvements Act must have expired or been
terminated. At the state level, regulatory approvals will be obtained or filings
made prior to the consummation of the merger, unless Con Edison and Northeast
otherwise agree. The states are Connecticut, Maine, Massachusetts, New
Hampshire, New Jersey, New York, Pennsylvania and Vermont. We expect that, as
part of the consummation of the merger, New Con Edison will become a registered
holding company under Section 5 of the Public Utility Holding Company Act of
1935.

    Consolidated Edison, Inc., is a public utility holding company for
Consolidated Edison Company of New York, Inc. and Orange and Rockland
Utilities, Inc. and is not itself an operating company. Con Edison of New York
provides electric service to over three million customers and gas to over a
million customers in New York City and Westchester County. Con Edison of New
York also supplies steam service to customers in parts of Manhattan. Orange and
Rockland provides electric service to over 250,000 customers and gas to over
100,000 customers in southeastern New York State and adjacent sections of New
Jersey and Pennsylvania. For the year ending December 31, 1999, Con Edison had
approximately $7.5 billion in consolidated operating revenues and
$700.6 million in net consolidated income.

    Con Edison has four non-utility subsidiaries which provide electric and gas
supply services, invest in energy infrastructure projects, and develop and
manage infrastructure for a communications business.

NORTHEAST UTILITIES

    Northeast Utilities is a public utility holding company for a number of
companies comprising the Northeast Utilities system and is not itself an
operating company. Through The Connecticut Light and Power Company, Public
Service Company of New Hampshire and Western Massachusetts Electric Company
(each a wholly owned subsidiary of Northeast), Northeast provides retail
electric service to over 1.7 million customers in Connecticut, New Hampshire and
western Massachusetts. For the year ending December 31, 1999, Northeast had
approximately $4.47 billion in consolidated operating revenues and consolidated
net income equal to $34.2 million. In June 1999, Northeast entered into an
agreement to acquire Yankee Energy System, Inc. The merger is expected to become
effective as early as the first quarter of 2000. Yankee, through its wholly
owned subsidiary, Yankee Gas Services Company, is the largest natural gas
distributor in Connecticut based upon revenues and number of customers.

    Northeast has a number of unregulated subsidiaries which provide
telecommunications, energy management and marketing and other energy related
services.

    Con Edison and Northeast do not anticipate making any changes to their
dividend policies prior to the consummation of the merger; however, the Con
Edison and Northeast Boards will continue to evaluate their respective dividend
policies in light of business, financial and regulatory considerations. The most
recent quarterly dividend declared by Con Edison was $.545 per share payable on
March 15, 2000. Con Edison's current dividend is $2.18 per common share on an
annual basis. The most recent quarterly dividend declared by Northeast was $.100
per share payable on March 31, 2000.

                                       12
<PAGE>
    We expect that after the merger, New Con Edison will continue the dividend
of Con Edison at the time of the merger. As a result, based upon Con Edison's
current dividend, New Con Edison's estimated aggregate annual dividend payments
would be approximately $143.7 million greater than those of Con Edison. Although
this increase in aggregate dividend payments will impact New Con Edison's
liquidity, it is not expected to have an adverse effect on New Con Edison's
business. The payment of dividends by New Con Edison, however, will be subject
to approval and declaration by the New Con Edison Board of Directors, and will
depend on a variety of factors, including business, financial and regulatory
considerations.

<PAGE>
                      RISK FACTORS RELATING TO THE MERGER

    SHAREHOLDERS OF CON EDISON AND NORTHEAST SHOULD CONSIDER CAREFULLY ALL THE
INFORMATION CONTAINED IN THIS JOINT PROXY STATEMENT/PROSPECTUS, INCLUDING THE
FOLLOWING MATTERS:

FLUCTUATIONS IN TRADING PRICE OF CON EDISON COMMON SHARES COULD RESULT IN STOCK
  CONSIDERATION THAT MAY BE LESS THAN OR GREATER THAN $25.00

    The exchange ratio relating to the Northeast shareholders' stock election in
the merger will be determined, subject to adjustments described in "The Merger
Agreement--Merger Consideration," by dividing $25.00 by the weighted average
trading price of Con Edison common shares over 20 trading days randomly selected
from the 40 trading days ending five trading days prior to the closing. However,
the Con Edison share price used to calculate the exchange ratio will not be less
than $36.00 nor greater than $46.00. This means that it is possible that
Northeast shareholders electing to receive New Con Edison common stock will
receive merger consideration valued at less than $25.00, since the denominator
used in calculating the exchange ratio will not be less than $36.00 regardless
of what happens to the price of Con Edison common shares shortly before the
merger. Similarly, this means that Northeast shareholders so electing could also
receive New Con Edison common stock having a value greater than $25.00, since
such denominator will not be greater than $46.00. It is important to note that
the price of Con Edison common shares reflects numerous factors including
investor perception of the utility industry in general as well as
company-specific circumstances.

    In addition, the price of Con Edison common shares (and New Con Edison
shares) could very well be different from the average trading price used in
calculating the exchange ratio because of market price fluctuations. Under the
merger agreement, neither Con Edison nor Northeast may terminate the merger
agreement based solely on fluctuation in the price of Con Edison common shares.
See "The Merger Agreement--Merger Consideration."

    A chart illustrating the possible values of the merger consideration to be
received by Northeast shareholders is also contained in this joint proxy
statement/prospectus. See "Summary."

CASH AND/OR STOCK PAID IN THE MERGER MAY BE DIFFERENT THAN WHAT NORTHEAST
  SHAREHOLDERS ELECT

    Northeast shareholders making elections for cash or stock may not receive
what they elect. The aggregate number of Northeast common shares that will be
converted into the right to receive cash consideration may not exceed 50% of the
number of Northeast common shares eligible to receive the merger consideration.
In addition, the aggregate number of Northeast common shares that will be
converted into the right to receive shares of New Con Edison common stock may
not exceed 50% of the number of Northeast common shares eligible to receive the
merger consideration. If New Con Edison common stock is oversubscribed by the
Northeast shareholders, a Northeast shareholder who elected to receive New Con
Edison common stock may receive part of his or her consideration in the form of
cash. If cash is oversubscribed by the Northeast shareholders, a Northeast
shareholder who elected to receive cash may receive part of his or her
consideration in the form of New Con Edison common stock. See "The Merger
Agreement--Allocation and Proration."

DELAYS IN THE NORTHEAST NUCLEAR FACILITIES DIVESTITURE COULD RESULT IN NORTHEAST
  SHAREHOLDERS NOT RECEIVING THE ADDITIONAL $1.00 ADJUSTMENT TO THE MERGER
  CONSIDERATION

    The merger agreement provides for an adjustment of an additional $1.00 in
respect of consideration to be paid to Northeast shareholders if Northeast's
subsidiaries enter into binding agreements to sell their interests in the
Millstone nuclear station which meet conditions described in this joint proxy
statement/prospectus.

    On July 7, 1999, the Connecticut Department of Public Utility Control issued
a decision on the determination of the minimum bids to be utilized in the
auction process to dispose of the Millstone nuclear station. On December 29,
1999, the Connecticut Office of Consumer Counsel filed a motion

                                       14
<PAGE>
with the Connecticut Superior Court for a partial stay of the decision which, if
granted, would stay the fixing of the minimum bid prices for the nuclear units.
Oral argument was held on February 14, 2000, and the parties are currently
awaiting an answer on the Consumer Counsel's motion. Although Northeast believes
that it is highly unlikely that such a stay will be granted, such a stay would
delay the commencement of the auction process for the Millstone nuclear station
and adversely affect Northeast's ability to meet the nuclear divestiture
condition described above. Because of the uncertainties relating to the auction
and approval process, including the disposition of the Consumer Counsel motion,
there can be no assurance that Northeast's subsidiaries will enter into these
agreements and that the Northeast shareholders will receive the benefits of the
adjustment of an additional $1.00 in respect of the merger consideration. For
information on the status of the Millstone divestiture, see "The Merger
Agreement--Merger Consideration."

DELAY IN REGULATORY APPROVALS WILL DELAY AND POSSIBLY PREVENT THE MERGER

    The consummation of the merger is conditioned upon receiving approval from
various governmental regulatory authorities. These include:

    - approval by or filing with the relevant utility regulatory agencies in
      Connecticut, Maine, Massachusetts, New Hampshire, New Jersey, New York,
      Pennsylvania and Vermont;

    - approval by the Securities and Exchange Commission under the Public
      Utility Holding Company Act of 1935;

    - approval by the Federal Energy Regulatory Commission under the Federal
      Power Act;

    - approval by the Nuclear Regulatory Commission under the Atomic Energy Act;
      and

    - the expiration or termination of the applicable waiting period under the
      Hart-Scott-Rodino Antitrust Improvements Act.

    While the parties expect to obtain the required regulatory approvals within
5 to 14 months, Con Edison and Northeast cannot be certain that all of the
required approvals and consents will be obtained, nor can they be certain that
the approvals and consents will be obtained within the time contemplated by the
merger agreement. A delay in obtaining the required approvals and consents will
delay and possibly prevent the consummation of the merger. In addition, Con
Edison and Northeast may obtain the required approvals and consents, but with
terms or conditions that may have a material adverse effect on Con Edison,
Northeast or New Con Edison. Con Edison will not be obligated to consummate the
merger if these terms or conditions would have a material adverse effect on Con
Edison, Northeast or New Con Edison and its prospective subsidiaries. Northeast
will not be obligated to consummate the merger if these terms or conditions
would have a material adverse effect on Con Edison or New Con Edison and its
prospective subsidiaries.

    For additional information on the required regulatory approvals, see
"Regulatory Matters" on page 75.

DIFFICULTIES IN INTEGRATING THE BUSINESS OPERATIONS OF THE TWO COMPANIES MAY
  RESULT IN THE FAILURE TO SUCCESSFULLY IMPLEMENT THE MERGER, ACHIEVE CASH
  SAVINGS AND REALIZE THE OTHER ANTICIPATED BENEFITS FROM THE MERGER

    In approving the merger, the Con Edison Board of Directors and the Northeast
Board of Trustees considered the potential complementary effects of combining
the two companies' assets, personnel and operating skills. Integrating
businesses, however, involves a number of special risks, including the
possibility that management may be distracted from regular business concerns by
the need to integrate operations, unforeseen difficulties in integrating
operations and systems, problems assimilating and retaining employees and
potential adverse short-term effects on operating results. While both companies
have substantial recent experience in merging business operations, there can be
no

                                       15
<PAGE>
assurance that the merger will be successfully implemented or that the combined
company will achieve the cost savings or realize the other benefits anticipated
from the merger.

SUBSTANTIAL CHANGES AFFECTING THE ELECTRIC AND GAS UTILITY INDUSTRIES COULD
  ADVERSELY AFFECT THE COMPANIES

    The merger will combine two companies that are currently affected by recent
developments in the electric and gas utility industries, including
restructuring, deregulation and increased competition. Because Con Edison and
Northeast and their subsidiaries are regulated at the federal level and in a
number of the states, the two companies (and New Con Edison after the merger)
have been and will continue to be impacted by legislative and regulatory
developments. After the merger, New Con Edison will continue to be subject to
extensive federal regulation as well as regulation in each of the following
jurisdictions: Connecticut, Maine, Massachusetts, New Hampshire, New Jersey, New
York, Pennsylvania and Vermont. Each of these jurisdictions has implemented, is
in the process of implementing or possibly will implement changes to the
regulatory and legislative framework applicable to the electric and gas
utilities industry. The continuing effects of changes that have been
implemented, the possible effects of changes under consideration and the
possible effects of changes that may occur in the future could have a material
adverse effect on Con Edison, Northeast or New Con Edison. Moreover, increased
competition resulting from legislative changes, regulatory changes or otherwise
may create greater risks to the stability of utility earnings generally. In a
deregulated environment, formerly regulated utility companies that are not
responsive to a competitive energy marketplace could suffer erosion in market
share, revenues and profits as competitors gain access to their service
territories.

                      UNAUDITED COMPARATIVE PER SHARE DATA

    Set forth below are the earnings, cash dividends and book value per common
share data separately for Con Edison and Northeast on a historical basis, for
Northeast on a pro forma basis (to reflect the proposed acquisition by Northeast
of Yankee), for New Con Edison on a pro forma combined basis and for Northeast
on a per share equivalent pro forma basis.

    The New Con Edison unaudited pro forma combined earnings per share was
derived from the unaudited pro forma combined financial statements and related
notes thereto presented on pages 93 to 97 herein. Book value per share for the
pro forma combined presentation is based upon outstanding Con Edison shares,
adjusted to include the estimated number of New Con Edison shares to be issued
to Northeast Shareholders in the merger. In determining the number of New Con
Edison shares to be issued to Northeast shareholders, it was assumed that 50% of
the outstanding Northeast common shares were exchanged for shares of New Con
Edison common stock at an exchange ratio of .646 shares of New Con Edison common
stock per Northeast common share. It was also assumed that 50% of the
outstanding Northeast common shares were exchanged for $26.50 per Northeast
common share.

    Con Edison and Northeast have assumed .646 as an exchange ratio and $26.50
as a cash payment because those numbers reflect the satisfaction of the
divestiture condition, a closing on December 31, 2000, and, in the case of the
assumed exchange ratio, an assumed Con Edison share price of $41.00. See
"Summary--General--What You Will Receive in the Merger--Northeast Shareholders."
The satisfaction of the divestiture condition has been assumed because, although
there can be no assurance, Con Edison and Northeast believe it is more likely
than not that the condition will be satisfied. See "Risk Factors--Uncertainties
Relating to Northeast Nuclear Facilities Divestiture." A closing on
December 31, 2000, has been assumed because that date represents the approximate
midpoint as to when Con Edison and Northeast expect to complete the regulatory
approval process for the merger. A Con Edison share price of $41.00 has been
assumed because it represents the midpoint of the price collar established for
Con Edison's share price.

    The per share equivalent pro forma combined data for Northeast shares were
derived by multiplying the New Con Edison pro forma combined data by the assumed
exchange ratio of .646 shares of New Con Edison common stock per Northeast
common share.

    You should read the information below together with Con Edison's and
Northeast's historical financial statements and related notes contained in the
annual reports and other information that the companies have filed with the
Securities and Exchange Commission and incorporated herein by reference and the
unaudited pro forma combined condensed financial statements and related notes
thereto presented on pages 93 to 102 herein. See "Where You Can Find More
Information" on page 117. The unaudited pro forma combined data below is for
illustrative purposes only. The companies may have performed differently had
they always been combined. You should not rely on this information as being
indicative of the historical results that would have been achieved had the
companies always been combined or the future results that the combined company
will experience after the merger.

(a) This per share data gives effect to the proposed acquisition by Northeast of
    Yankee.

(b) The pro forma per share dividend data does not reflect the expectation that
    New Con Edison will continue the dividend of Con Edison at the time of the
    merger (currently $2.18 per common share on an annual basis). As a result,
    based upon Con Edison's current dividend, New Con Edison's estimated
    aggregate annual dividend payments would be approximately $143.7 million
    greater than those of Con Edison. Although this increase in aggregate
    dividend payments will impact New Con Edison's liquidity, it is not expected
    to have an adverse effect on New Con Edison's business. It is expected that
    New Con Edision will pay future dividends out of dividends from
    subsidiaries.

(c) Reflects basic earnings per common share. Diluted earnings per common share
    for the period were $3.13.

    The chart below illustrates the effect on earnings per share data from
changes to the assumed exchange ratio based upon different sets of assumptions
regarding variables specified in the merger agreement:

                         THE CON EDISON SPECIAL MEETING

    WE ARE FURNISHING THIS JOINT PROXY STATEMENT/PROSPECTUS TO SHAREHOLDERS OF
CON EDISON AS PART OF THE SOLICITATION OF PROXIES BY THE CON EDISON BOARD OF
DIRECTORS FOR USE AT THE CON EDISON SPECIAL MEETING.

DATE, TIME AND PLACE

    Con Edison will hold its special meeting on Friday, April 14, 2000, at
2:00 p.m., local time, at 4 Irving Place, 19th Floor, New York, New York 10003.

PURPOSE OF CON EDISON SPECIAL MEETING

    At the Con Edison special meeting, we are asking holders of record of Con
Edison common shares to consider and vote on a proposal to approve and adopt the
merger agreement among Con Edison, Northeast and New Con Edison, providing for
the merger. See "The Merger" and "The Merger Agreement."

    The Con Edison Board of Directors has approved and adopted the merger
agreement, the merger and the other transactions contemplated by the merger
agreement and has determined that the merger and the other transactions
contemplated by the merger agreement are consistent with, and in furtherance of,
the best interest of Con Edison and its shareholders.

    THE CON EDISON BOARD OF DIRECTORS RECOMMENDS THAT CON EDISON SHAREHOLDERS
VOTE FOR THE APPROVAL AND ADOPTION OF THE MERGER AGREEMENT.

CON EDISON RECORD DATE; SHARES ENTITLED TO VOTE; QUORUM

    Only holders of record of Con Edison common shares at the close of business
on February 22, 2000, the Con Edison record date, are entitled to notice of and
to vote at the Con Edison special meeting. On February 22, 2000, approximately
212,842,190 Con Edison common shares were issued and outstanding and held by
approximately 116,043 holders of record. A quorum will be present at the Con
Edison special meeting if the holders of a majority of the votes of shares
entitled to vote on the Con Edison record date are represented in person or by
proxy. If a quorum is not present at the Con Edison special meeting, we expect
that the Con Edison special meeting will be adjourned or postponed to solicit
additional proxies. Holders of record of Con Edison common shares on the Con
Edison record date are entitled to one vote per share at the Con Edison special
meeting on the proposal to approve the merger agreement.

VOTE REQUIRED

    The approval of the merger agreement by Con Edison shareholders requires the
affirmative vote of at least a majority of the shares outstanding and entitled
to vote at a special meeting of the shareholders as of the Con Edison record
date, either in person or by proxy, voting as a single class.

VOTING BY CON EDISON DIRECTORS AND EXECUTIVE OFFICERS

    At the close of business on December 31, 1999, directors and executive
officers of Con Edison owned and were entitled to vote less than 1% of the Con
Edison common shares outstanding on that date. Each Con Edison director and
executive officer has indicated his or her present intention to vote, or cause
to be voted, the Con Edison common shares owned by him or her for the approval
of the merger agreement.

VOTING OF PROXIES

    All shares represented by properly executed proxies received in time for the
Con Edison special meeting will be voted at the Con Edison special meeting in
the manner specified by the shareholders giving those proxies. Properly executed
proxies that do not contain voting instructions will be voted for the approval
of the merger agreement.

    In addition to manually executing and returning a proxy by mail, Con Edison
shareholders may vote by telephone or computer. If voting by telephone or
computer, the shareholder should dial the toll-free number or access the
Internet address, in each case as indicated in the shareholder's proxy.

                                       22
<PAGE>
The shareholders will then be prompted to enter the control number printed on
his or her proxy and to follow the subsequent instructions.

    Con Edison common shares represented at the Con Edison special meeting but
not voting, including Con Edison common shares for which proxies have been
received but for which holders of shares have abstained, will be treated as
present at the Con Edison special meeting for purposes of determining the
presence or absence of a quorum for the transaction of all business.

    Only shares affirmatively voted for the approval of the merger agreement,
including properly executed proxies that do not contain voting instructions,
will be counted as favorable votes for the proposal. AN ABSTENTION OR FAILURE TO
VOTE WILL HAVE THE SAME EFFECT AS A VOTE AGAINST APPROVAL OF THE MERGER
AGREEMENT. Also, under New York Stock Exchange rules, brokers who hold Con
Edison common shares in street name for customers who are the beneficial owners
of those shares may not give a proxy to vote those shares without specific
instructions from those customers. If a Con Edison shareholder owns shares
through a broker and attends the special meeting, the shareholder should bring a
letter from his or her broker identifying him or her as the beneficial owner of
the shares and authorizing the shareholder to vote.

    The persons named as proxies by a Con Edison shareholder may propose and
vote for one or more adjournments of the Con Edison special meeting, including
adjournments to permit further solicitations of proxies. No proxy voted against
the proposal to approve the merger agreement will be voted in favor of any
adjournment or postponement.

    Con Edison does not expect that any matter other than the proposal to
approve the merger agreement will be brought before the Con Edison special
meeting. If, however, other matters are properly presented to the meeting, the
persons named as proxies will vote in accordance with the recommendation of the
Board of Directors.

REVOCABILITY OF PROXIES

    Voting by use of a proxy on the enclosed form, telephone or computer does
not preclude a Con Edison shareholder from voting in person at the Con Edison
special meeting. A Con Edison shareholder may revoke a proxy at any time prior
to its exercise by filing with Con Edison a duly executed revocation of proxy,
by submitting a duly executed proxy, telephone or computer vote to Con Edison
with a later date or by appearing at the Con Edison special meeting and voting
in person. Con Edison shareholders may revoke a proxy by any of these methods,
regardless of the method used to cast his or her previous vote. Attendance at
the Con Edison special meeting without voting will not itself revoke a proxy.

SOLICITATION OF PROXIES

    Con Edison will bear the cost of the solicitation of proxies from its
shareholders. In addition to solicitation by mail, the directors, officers and
employees of Con Edison and its subsidiaries may solicit proxies from Con Edison
shareholders by telephone or other electronic means or in person. Arrangements
will also be made with brokerage houses and other custodians, nominees and
fiduciaries for the forwarding of solicitation materials to the beneficial
owners of shares held of record by these persons, and Con Edison will reimburse
them for their reasonable out-of-pocket expenses.

    Con Edison will mail a copy of this joint proxy statement/prospectus to each
holder of record of Con Edison common shares on the Con Edison record date.

    Con Edison has retained Morrow & Co. to assist in the solicitation of
proxies from banks, brokerage firms, nominees, insitutional holders and
individual investors for a fee of $50,000 plus reimbursement for expenses. To
date, none of such fee has paid.

    CON EDISON SHAREHOLDERS WILL NOT BE REQUIRED TO EXCHANGE THEIR CON EDISON
SHARE CERTIFICATES AS A RESULT OF THE MERGER. ACCORDINGLY, CON EDISON
SHAREHOLDERS SHOULD NOT SEND IN THEIR CON EDISON SHARE CERTIFICATES.

                         THE NORTHEAST SPECIAL MEETING

    WE ARE FURNISHING THIS JOINT PROXY STATEMENT/PROSPECTUS TO SHAREHOLDERS OF
NORTHEAST AS PART OF THE SOLICITATION OF PROXIES BY THE NORTHEAST BOARD OF
TRUSTEES FOR USE AT THE NORTHEAST SPECIAL MEETING.

DATE, TIME AND PLACE

    Northeast will hold its special meeting on Friday, April 14, 2000, at
2:00 p.m., local time, at the Hartford Civic Center, One Civic Center Plaza,
Hartford, Connecticut 06103.

PURPOSE OF NORTHEAST SPECIAL MEETING

    At the Northeast special meeting, we are asking holders of record of
Northeast common shares to consider and vote on proposals to approve the trust
agreement amendments and to approve the merger. See "The Merger" and "The Merger
Agreement."

    The Northeast Board of Trustees has approved the trust agreement amendments
and approved the merger and the other transactions contemplated by the merger
agreement and has determined that the trust agreement amendments, the merger and
the other transactions contemplated by the merger agreement are consistent with,
and in furtherance of, the best interest of Northeast and its shareholders.

    THE NORTHEAST BOARD OF TRUSTEES RECOMMENDS THAT NORTHEAST SHAREHOLDERS VOTE
FOR THE APPROVAL OF THE TRUST AGREEMENT AMENDMENTS AND THE APPROVAL OF THE
MERGER.

NORTHEAST RECORD DATE; SHARES ENTITLED TO VOTE; QUORUM

    Only holders of record of Northeast common shares at the close of business
on February 22, 2000, the Northeast record date, are entitled to notice of and
to vote at the Northeast special meeting. On February 22, 2000, approximately
137,388,633 Northeast common shares were issued and outstanding and held by
approximately 80,592 holders of record. A quorum will be present at the
Northeast special meeting if at least a majority of the Northeast common shares
issued and outstanding and entitled to vote on the Northeast record date are
represented in person or by proxy. If a quorum is not present at the Northeast
special meeting, we expect that the Northeast special meeting will be adjourned
or postponed to solicit additional proxies. Holders of record of Northeast
common shares on the Northeast record date are entitled to one vote per share at
the Northeast special meeting on the proposals to approve the trust agreement
amendments and the merger agreement.

VOTE REQUIRED

    The amendment of the trust agreement and the approval of the merger
agreement each requires the affirmative vote of the holders of at least
two-thirds of the shares outstanding and entitled to vote at a special meeting
of the shareholders as of the Northeast record date, either in person or by
proxy, voting as a single class. We cannot complete the merger without the
approval of both the trust agreement amendments and the merger agreement.

VOTING BY NORTHEAST TRUSTEES AND EXECUTIVE OFFICERS

    At the close of business on January 31, 2000, trustees and executive
officers of Northeast owned and were entitled to vote approximately 0.2% of the
Northeast common shares outstanding on that date. Each Northeast trustee and
executive officer has indicated his or her present intention to vote, or cause
to be voted, the Northeast common shares owned by him or her for the approval of
the trust agreement amendments and the approval of the merger agreement.

VOTING OF PROXIES

    All shares represented by properly executed proxies received in time for the
Northeast special meeting will be voted at the Northeast special meeting in the
manner specified by the shareholders giving those proxies. Properly executed
proxies that do not contain voting instructions will be voted for the approval
of the trust agreement amendments and the approval of the merger agreement.

    Northeast common shares represented at the Northeast special meeting but not
voting, including Northeast common shares for which proxies have been received
but for which holders of shares have abstained, will be treated as present at
the Northeast special meeting for purposes of determining the presence or
absence of a quorum for the transaction of all business.

    Only shares affirmatively voted for the approval of the merger agreement,
including properly executed proxies that do not contain voting instructions,
will be counted as favorable votes for the proposals. AN ABSTENTION OR FAILURE
TO VOTE WILL HAVE THE SAME EFFECT AS A VOTE AGAINST APPROVAL OF THE TRUST
AGREEMENT AMENDMENTS AND THE MERGER AGREEMENT. Under New York Stock Exchange
rules, brokers who hold Northeast common shares in street name for customers who
are the beneficial owners of those shares may not give a proxy to vote those
shares without specific instructions from those customers. If a Northeast
shareholder owns shares through a broker and attends the special meeting, the
shareholder should bring a letter from his or her broker identifying him or her
as the beneficial owner of the shares and authorizing the shareholder to vote.

    The persons named as proxies by a Northeast shareholder may propose and vote
for one or more adjournments of the Northeast special meeting, including
adjournments to permit further solicitations of proxies. No proxy voted against
the proposal to approve the trust agreement amendments or the proposal to
approve the merger agreement will be voted in favor of any adjournment or
postponement.

    Northeast does not expect that any matter other than the proposals to
approve the trust agreement amendments and the merger agreement will be brought
before the Northeast special meeting. If, however, other matters are properly
presented to the meeting, the persons named as proxies will vote in accordance
with the recommendation of the Board of Trustees.

REVOCABILITY OF PROXIES

    Voting by use of a proxy on the enclosed form does not preclude a Northeast
shareholder from voting in person at the Northeast special meeting. A Northeast
shareholder may revoke a proxy at any time prior to its exercise by filing with
Northeast a duly executed revocation of proxy, by submitting a duly executed
proxy to Northeast bearing a later date or by appearing at the Northeast special
meeting and voting in person. Attendance at the Northeast special meeting
without voting will not itself revoke a proxy.

SOLICITATION OF PROXIES

    Northeast will bear the cost of the solicitation of proxies from its
shareholders. In addition to solicitation by mail, the trustees, officers and
employees of Northeast and its subsidiaries may solicit proxies from Northeast
shareholders by telephone or other electronic means or in person. Arrangements
will also be made with brokerage houses and other custodians, nominees and
fiduciaries for the forwarding of solicitation materials to the beneficial
owners of shares held of record by these persons, and Northeast will reimburse
them for their reasonable out-of-pocket expenses.

    Northeast will mail a copy of this joint proxy statement/prospectus to each
holder of record of Northeast common shares on the Northeast record date.

    Northeast has retained Morrow & Co. to assist in the solicitation of proxies
from banks, brokerage firms, nominees, institutional holders and individual
investors for a fee of $60,000 plus reimbursement for expenses. To date, none of
such fee has been paid.

                                   THE MERGER

    THE DISCUSSION IN THIS JOINT PROXY STATEMENT/PROSPECTUS OF THE MERGER AND
THE PRINCIPAL TERMS OF THE MERGER AGREEMENT DATED AS OF OCTOBER 13, 1999,
AMENDED AND RESTATED AS OF JANUARY 11, 2000, AMONG CON EDISON, NORTHEAST AND NEW
CON EDISON, IS SUBJECT TO, AND IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO, THE
MERGER AGREEMENT, A COPY OF WHICH IS ATTACHED TO THIS JOINT PROXY
STATEMENT/PROSPECTUS AS ANNEX A AND IS INCORPORATED HEREIN BY REFERENCE.

GENERAL DESCRIPTION OF THE MERGER

    Under the merger agreement, Con Edison will merge into New Con Edison, with
New Con Edison being the surviving corporation, and N Acquisition LLC, a
Massachusetts limited liability company and indirect wholly owned subsidiary of
Con Edison, will merge with and into Northeast, with Northeast being the
surviving entity. Upon completion of the merger, the holders of Con Edison
common shares and Northeast common shares will together own all of New Con
Edison's outstanding shares of common stock, New Con Edison will own all of the
assets of Con Edison and Northeast will be a wholly owned subsidiary of New Con
Edison.

BACKGROUND TO THE MERGER

    GENERAL

    Prior to entering merger discussions with Con Edison, Northeast had
carefully followed recent developments in the electric and natural gas
industries in the northeastern United States that have made it difficult for
medium-sized utility companies to compete as effectively as larger utilities. In
early 1998, Northeast began to develop a strategic plan to focus its regulated
subsidiaries on electric and natural gas distribution, while focusing its
unregulated affiliates on energy marketing and generation. To effectively
compete in each of these businesses, Northeast determined that it would need to
increase its scale of operations and the size of its customer base.

    Northeast determined that possible mergers with neighboring electric and
natural gas distribution companies would help achieve its strategic goals. In
that regard, Northeast's recently announced proposed merger with Yankee, the
parent of Connecticut's largest natural gas distribution company was an
important step in achieving these goals. Over the past year, Northeast also
engaged in confidential discussions with a number of other regional gas
distribution companies of a similar size to Yankee to explore various forms of
strategic transactions, including asset sales, acquisitions and mergers. None of
these other discussions, other than those with Yankee, progressed past the stage
of preliminary discussions, and all such other discussions were terminated.
Northeast concluded that a business combination with a larger partner, such as
Con Edison, would be required to attain the size necessary to compete in the
northeast energy markets. During the past year, Northeast had preliminary
discussions with one other utility company of a comparable size to Con Edison.
These discussions were very brief and were terminated during the early part of
Northeast's discussions with Con Edison. See "--Northeast's Reasons for the
Merger."

    Con Edison has also focused on its core transmission and distribution
business. It has pursued a strategy of growing this business in its service
territory and has carefully pursued expansion in the northeast region through
mergers and acquisitions. In addition to the transmission and distribution
business, Con Edison is applying its expertise in energy supply, energy delivery
and customer service to growing its unregulated businesses by focusing on
complementary energy and infrastructure-related services in the northeast.

    Con Edison has approached its mergers and acquisitions strategy in what it
believes to be a correctly planned and disciplined fashion. The recent merger
with Orange and Rockland Utilities, completed in July 1999, was an important
initial step to this strategy. The merger with Northeast is a

                                       26
<PAGE>
further important step in this strategy. Con Edison believes that the merger
with Northeast will reinforce Con Edison's position as one of the leading
electric and gas transmission and distribution companies in the country, in
terms of number of customers.

    DISCUSSIONS--GENERAL; OTHER

    On June 30, 1999, upon his initiation, Eugene R. McGrath, the Chairman,
President and Chief Executive Officer of Con Edison, informally met with Michael
G. Morris, the Chairman, President and Chief Executive Officer of Northeast and
discussed the possibility of a transaction between Con Edison and Northeast.

    On July 9, 1999, Joan S. Freilich, the Executive Vice President and Chief
Financial Officer of Con Edison, met with John H. Forsgren, the Executive Vice
President and Chief Financial Officer of Northeast, to conduct preliminary
conceptual discussions concerning a possible transaction between Con Edison and
Northeast. The subject matter of these discussions included the financial and
strategic plans of the two companies, the status of restructuring in each of
their relevant states of operation, and the possible desirability of a
transaction between Con Edison and Northeast.

    On July 12 and 13, the Northeast Board of Trustees held meetings focused
exclusively on a review of Northeast's business strategy. Considerable
discussion took place with respect to various strategic transactions, including
the possibility of a transaction with Con Edison.

    The possibility of a transaction between Con Edison and Northeast was
presented at a meeting of the Con Edison Board of Directors held on July 27,
1999. After discussing the potential transaction in general terms, the Con
Edison Board of Directors agreed that it would be in the best interest of Con
Edison and its shareholders to pursue discussions with Northeast. Transaction
structures and valuations of Northeast were not discussed or considered by the
Con Edison Board of Directors at the meeting.

    A confidentiality agreement was entered into by Con Edison and Northeast on
July 29, 1999. The agreement established that each party would provide the other
with appropriate data and records in order to allow the other party to evaluate
fully the merits of a potential transaction. Each party agreed that the
information furnished by the other party would be kept in confidence and not
disclosed to outside parties for the duration of the agreement.

    On August 13, 1999, Con Edison and Northeast provided each other with
financial forecasts concerning their respective companies. The financial
forecasts were used to determine whether going forward with the transaction
discussions would be advisable. Con Edison and Northeast each decided that,
based on the data available and set forth in the financial information provided,
continuing discussions between the companies would be in the best interest of
each company and their respective shareholders.

    On August 24, 1999, Con Edison's senior transaction team held a meeting to
discuss and review presentations regarding potential transaction structures.
This group also discussed other matters, including the valuation of Northeast
based on publicly available information as well as financial data provided by
Northeast. The group considered other topics including communications issues,
necessary regulatory approvals, the business of Northeast, the status of
restructuring proceedings, historical events affecting Northeast and other
matters.

    Ms. Freilich and Mr. Forsgren met again on September 7, 1999, to discuss
potential structures for the proposed transaction. The discussion topics
included the composition of the potential consideration, possible merger
structures and topics relating to the transaction process. At the meeting,
Ms. Freilich and Mr. Forsgren also discussed the valuation of Northeast and the
relative valuations of Con Edison and Northeast.

    On September 10, 1999, Mr. McGrath and Mr. Morris met to review the proposed
structures and the preliminary valuations of Northeast. After discussions,
Mr. McGrath and Mr. Morris came to the conclusion that both parties should
proceed with full-scale due diligence reviews in order to determine whether
attempting to finalize a transaction between Con Edison and Northeast would be
in the best interests of the companies and their respective shareholders.

    The Northeast Board of Trustees held a meeting on September 14, at which
topics discussed included the status and results of work that was ongoing with
respect to an evaluation of a potential transaction with Con Edison, a
preliminary updated valuation of Northeast by its investment bankers and a range
of potential merger consideration in a transaction with Con Edison. After
discussion, the Northeast Board encouraged management to continue its evaluation
of the potential transaction.

    The Con Edison Board of Directors held a meeting on September 28, 1999, at
which topics discussed included the strategic rationale for the transaction, the
results of the due diligence review of Northeast and the composition and range
of the potential merger consideration. After careful consideration of the
information provided, the Con Edison Board of Directors concluded that it would
be in the best interest of Con Edison and its shareholders to conduct
negotiations to finalize the terms of the proposed transaction.

    On September 29, 1999, John D. McMahon, Senior Vice President and General
Counsel of Con Edison, Cheryl W. Grise, Senior Vice President, Secretary and
General Counsel of Northeast, and counsel to Con Edison and Northeast met to
discuss the possible legal structures for the potential transaction, necessary
regulatory approvals, tax matters and other issues, including a timetable for
providing a draft merger agreement.

    From October 5, 1999 through October 12, 1999, Con Edison and Northeast and
their representatives held discussions and negotiations concerning material
terms of the potential transaction and concerning the documentation that would
ultimately govern any relationship between the parties. Also, previously and
during this period, Con Edison employees and representatives and Northeast
employees and representatives met both as groups and individually to discuss
various issues associated with the potential transaction, including issues
associated with due diligence, communications, regulatory approvals, the
businesses of Con Edison and Northeast and other matters.

    On October 7, 1999, at a special meeting of the Executive Committee of the
Northeast Board of Trustees, Mr. Morris discussed with the committee the
material terms of a potential transaction with Con Edison that were emerging and
the preliminary results of management's due diligence investigation of Con
Edison.

    The Con Edison Board of Directors held a special meeting on October 11,
1999, to review the terms of the transaction that had been negotiated between
Con Edison and Northeast. The material open issues outstanding between the
parties were also discussed and considered at this meeting.

    The Northeast Board of Trustees held a special meeting on October 11, 1999,
to review the terms of the transaction that had been negotiated between Con
Edison and Northeast. The material open issues outstanding between the parties
were also discussed and considered at this meeting.

    During the day and early evening of October 12, 1999, Con Edison and
Northeast and their representatives held discussions during which the final open
issues with respect to the definitive terms of the transaction were resolved.

    The Con Edison Board of Directors held another special meeting on
October 12, 1999 to review the terms of the merger agreement, the results of Con
Edison's due diligence investigation of Northeast and the impact of the merger
on employment agreements between Northeast and its employees and the effect of
the proposed transactions on Con Edison, its shareholders and other
constituencies. Also, at this meeting, representatives from Salomon Smith
Barney Inc. made presentations to the Con Edison

                                       28
<PAGE>
Board concerning the transaction and rendered an oral opinion, which was
subsequently confirmed in writing, to the effect that, as of such date, the
merger consideration was fair from a financial point of view to the Con Edison
shareholders. At this special meeting, the Con Edison Board of Directors
unanimously approved the merger and all related transactions and the merger
agreement. See "--Con Edison's Reasons for the Merger and the Con Edison Board
of Directors Recommendation."

    The Northeast Board of Trustees held a meeting on October 12, 1999 to review
the terms of the merger agreement, the results of Northeast's due diligence
investigation of Con Edison and the effect of the proposed transactions on
Northeast, its shareholders and other constituencies. Also, at this meeting,
representatives from Morgan Stanley & Co. Incorporated and SG Barr Devlin made
presentations to the Northeast Board concerning the transaction and each
rendered an opinion to the effect that, as of such date, the merger
consideration was fair from a financial point of view to the Northeast
shareholders. At this meeting, the Northeast Board of Trustees unanimously
approved the merger and all related transactions and the merger agreement. See
"--Northeast's Reasons for the Merger" and "--Recommendation of the Northeast
Board of Trustees."

    On the morning of October 13, 1999, the parties entered into the merger
agreement. The merger agreement was later amended and restated by the parties as
of January 11, 2000.

    DISCUSSIONS--MERGER CONSIDERATION

    Con Edison and Northeast discussed the premium to be paid for Northeast
common shares throughout much of the period of negotiations and discussions
leading up to the execution of the merger agreement on October 13, 1999.
Although possible valuations were discussed during this period and thus possible
prices, Con Edison made its first specific and detailed offer on October 8, 1999
proposing a base price of $25 for each Northeast common share with additional
consideration to be paid upon satisfaction of the divestiture condition and if
the closing of the transaction occurred after a specific date. At this time, Con
Edison also proposed a 50-50% allocation of the form of merger consideration
between stock and cash, subject to election and proration procedures. From
October 8 and thereafter the parties discussed and finally agreed upon the terms
of the divestiture condition and the amount payable if the merger closed after
an agreed upon date. On October 11, 1999, the parties formally discussed the
inclusion of a price collar mechanism in the transaction that would apply to the
exchange ratio in the merger consideration. This term was introduced by the
parties in order to address concerns about the effects of possibly changing
interest rates on share prices of utility companies, the potential for other
market price fluctuations and the desire of the parties to fix, within a range,
the number of shares issuable in the merger. From October 11 and thereafter the
parties discussed and finally agreed upon the terms of the price collar
mechanism.

    Although Con Edison is an experienced nuclear operator and believes nuclear
power to have meaningful commercial value, ownership of nuclear assets is not a
primary component of Con Edison's strategy. In that regard, Con Edison remains
concerned about the risks that can be associated with nuclear operations and
market perceptions of them. The additional consideration payable upon
satisfaction of the divestiture condition relating to the sale of Northeast's
Millstone nuclear facilities reflects Con Edison's higher valuation of Northeast
without the Millstone facilities due to concerns about nuclear operations, the
adverse effect that nuclear operations have had on Northeast and the risks
related to, and the potential adverse effect that those operations could have
on, New Con Edison's and Northeast's results of operations. The divestiture
condition and the additional consideration payable upon satisfaction of the
condition also provides increased value to Northeast's shareholders.

CON EDISON'S REASONS FOR THE MERGER AND THE CON EDISON BOARD OF DIRECTORS
  RECOMMENDATION

    At its meeting on October 12, 1999, after due consideration, the Con Edison
Board of Directors:

    - determined that the merger and the other transactions contemplated by the
      merger agreement are consistent with, and in furtherance of, the best
      interest of Con Edison and its shareholders;

    - approved and adopted the merger agreement, the merger and the other
      transactions contemplated by the merger agreement; and

    - recommended that Con Edison shareholders vote for the approval and
      adoption of the merger agreement.

    The Con Edison Board of Directors believes that the common vision of Con
Edison and Northeast and their complementary strategies, in combination with
their management, personnel, technical expertise and financial strength, will
create a company with capabilities and resources better positioned to succeed
and grow in the new competitive energy marketplace.

    Con Edison believes the merger joins two well-managed companies, providing
substantial strategic and financial benefits to Con Edison shareholders,
employees and customers. The combination of Con Edison and Northeast is expected
to provide New Con Edison with the size, resources and large customer base
necessary for achieving competitive investor returns in the rapidly changing
electricity and natural gas industries.

    Con Edison and Northeast anticipate estimated net merger savings in their
regulated businesses approximately equal to $1.3 billion over ten years and in
their unregulated businesses approximately equal to $180 million over ten years.
The cost savings estimates do not account for any sharing of cost savings with
customers that may be necessitated as part of the regulatory approval process
relating to the merger. The major components of the anticipated $1.3 billion of
regulated business net cost savings relate to labor, corporate and
administrative programs, potential purchasing economies and gas supply. Labor
accounts for approximately $952 million of gross cost savings and principally
represents headcount reductions of corporate and field personnel. Corporate and
administrative programs account for approximately $578 million of gross cost
savings, and principally represent a reduction in expenses associated with
administrative and general overhead, advertising, benefits, information services
and professional services. Purchasing economies account for approximately $157
million of gross cost savings and principally represent a reduction in
procurement and inventory expenses. Gas supply accounts for approximately $63
million of gross cost savings and principally represents a reduction in expenses
associated with purchasing and maintaining gas supply. The $1.3 billion of
estimated regulated business cost savings are net of estimated costs to achieve
such savings equal to approximately $356 million and savings relating to certain
initiatives unrelated to the merger (and thus not properly included) equal to
approximately $84 million. The costs to achieve the cost savings generally
represent approximately $98 million of expenses associated with severance, $166
million of expenses associated with integration efforts, $49 million of
transaction fees, $12 million of expenses associated with the regulatory process
and $31 million of various other costs. These estimates of cost savings, cost
savings components, costs to achieve and initiatives unrelated to the merger are
inherently uncertain and there can be no assurances as to the accuracy of any
such estimates.

    The cost savings estimates are based on a number of assumptions, including
that New Con Edison will be able to implement necessary cost savings mechanisms
such as headcount reductions, consolidation of geographically proximate
facilities and elimination of duplicative administrative programs within a
defined period. In addition, the cost savings estimates assume that New Con
Edison will be able to realize merger efficiencies such as purchasing economies
resulting from the increased size of the company. As mentioned above, the cost
savings estimates do not account for any sharing of cost savings with customers.

                                       30
<PAGE>
    In approving the merger and making these determinations and recommendations,
the Con Edison Board of Directors consulted with Con Edison management as well
as its outside legal counsel and financial advisors, and considered a number of
factors, including the following factors:

    - the benefits of the merger described above;

    - the review and analysis of each of Con Edison's and Northeast's business,
      financial condition, earnings, risks and prospects;

    - historical market prices and trading information with respect to the Con
      Edison common shares and Northeast common shares;

    - comparisons of historical financial measures for Con Edison and Northeast,
      including earnings, return on capital and cash flow, and comparisons of
      historical operational measures for Con Edison and Northeast;

    - the expectation that, assuming a closing prior to January 1, 2001, the
      merger would be dilutive to Con Edison shareholders in 2001 and accretive
      to Con Edison shareholders in 2002 and 2003;

    - the effect of the merger on the capital structure and financial ratios of
      Con Edison;

    - the possibility that the merger could result in a lower investment grade
      credit rating for Con Edison;

    - current industry, economic and market conditions and the prospects of
      further restructuring and consolidation in the electric and gas utility
      industries;

    - the risks of Northeast's nuclear generating facilities, including the
      continued incurrence of stranded costs in connection with the
      decommissioning of these facilities and general operating risks, and the
      steps Northeast was taking to divest the facilities;

    - the ability to complete the merger as a tax-free transaction for U.S.
      federal income tax purposes and to have the conversion of Con Edison
      common shares be tax-free to shareholders;

    - the expectation of synergies from the transaction resulting in cost
      savings and other benefits over time based in part upon an analysis that
      was jointly prepared by the managements of Con Edison and Northeast with
      the assistance of an outside consultant;

    - the possibility that varying levels of cost savings in respect of the
      regulated businesses achievable from the merger over time would be shared
      with customers of the regulated businesses of New Con Edison;

    - the terms and conditions of the merger agreement, including the conditions
      to closing, the potential termination fees payable, and the form and the
      amount of the merger consideration, including the payment of a portion of
      the merger consideration in cash;

    - the proposed composition of senior management and the Board of Directors
      of New Con Edison;

    - the analyses, presentations and opinion of Salomon Smith Barney Inc. to
      the effect that, as of October 12, 1999, and based upon and subject to the
      various assumptions and limitations set forth therein, the exchange ratio
      applicable to Con Edison shareholders in the merger was fair, from a
      financial point of view, to the holders of Con Edison common shares (the
      written opinion of Salomon Smith Barney Inc. is attached as Annex B to
      this joint proxy statement/ prospectus);

    - the benefits to Con Edison's shareholders, customers and employees
      resulting from the fact that New Con Edison's corporate headquarters will
      be located in New York City and that Con

                                       31
<PAGE>
      Edison's subsidiaries will maintain offices for utility operations in New
      York, New Jersey and Pennsylvania;

    - the potential benefits to Con Edison's employees from the expanded
      opportunities available as part of a larger organization;

    - the benefits to Con Edison's customers from the potential synergies
      resulting from the merger while the operations from Con Edison's utility
      subsidiaries remain substantially unchanged;

    - that while the merger is likely to be completed, there are risks
      associated with obtaining necessary regulatory approvals, and as a result
      of this and other conditions to the completion of the merger, it is
      possible that the merger may not be completed even if approved by
      shareholders;

    - the impact of regulations under various state and federal laws, including
      the additional regulatory oversight that would result from the addition of
      public utility operations in Connecticut, New Hampshire and Massachusetts,
      and the issues involved in the regulation of New Con Edison and Northeast
      as registered holding companies under the Public Utility Holding Company
      Act;

    - the problems inherent in merging the operations of two large companies,
      including the possibility that management may be distracted from regular
      business concerns by the need to integrate operations, unforeseen
      difficulties in integrating operations and systems, problems assimilating
      and retaining employees and potential adverse short-term effects on
      operating results of the combined company;

    - the interests that certain executive officers and directors of Con Edison
      may have with respect to the merger in addition to their interests as
      shareholders of Con Edison; and

    - the interests that certain executive officers of Northeast may have with
      respect to the merger in addition to their interests as shareholders of
      Northeast.

    The Con Edison Board of Directors believed that, overall, the potential
benefits of the merger to Con Edison and its shareholders outweighed the risks.

    This discussion of the information and factors considered by the Con Edison
Board of Directors in making its decision is not intended to be exhaustive but
is believed to include all material factors considered by the Con Edison Board
of Directors. In view of the wide variety of factors considered in connection
with its evaluation of the merger and the complexity of these matters, the Con
Edison Board of Directors did not find it useful to and did not attempt to
quantify, rank or otherwise assign relative weights to these factors. The Con
Edison Board of Directors relied on the experience and expertise of Salomon
Smith Barney Inc., its financial advisor, for quantitative analysis of the
financial terms of the merger. In addition, the Con Edison Board of Directors
did not undertake to make any specific determination as to whether any
particular factor, or any aspect of any particular factor, was favorable or
unfavorable to its ultimate determination, but rather the Con Edison Board of
Directors conducted an overall analysis of the factors described above,
including through discussions with and questioning of Con Edison's management
and legal, financial and accounting advisors. In addition, individual members of
the Con Edison Board of Directors may have given different weight to different
factors.

THE BOARD OF DIRECTORS OF CON EDISON RECOMMENDS THAT THE HOLDERS OF CON EDISON
COMMON SHARES VOTE FOR THE APPROVAL AND ADOPTION OF THE MERGER AGREEMENT.

OPINION OF CON EDISON'S FINANCIAL ADVISOR

    Salomon Smith Barney Inc. was retained to act as financial advisor to Con
Edison in connection with the merger. Pursuant to Salomon Smith Barney's
engagement letter, Salomon Smith Barney rendered an opinion to the Con Edison
Board of Directors on October 12, 1999 to the effect that, based upon and
subject to the considerations set forth in the opinion, Salomon Smith Barney's
experience as investment bankers, its work described below and other factors it
deemed relevant, as of that date, the exchange ratio of one share of New Con
Edison common stock for each Con Edison common share in the Con Edison merger
was fair, from a financial point of view, to the holders of Con Edison common
shares. Salomon Smith Barney took into account the related acquisition of
Northeast and the consideration to be paid in connection with the Northeast
merger in its analysis of this exchange ratio. Salomon Smith Barney's October
12, 1999 opinion will not be reconfirmed.

    The full text of Salomon Smith Barney's opinion, which sets forth the
assumptions made, general procedures followed, matters considered and limits on
the review undertaken, is included as Annex B to this document. The summary of
Salomon Smith Barney's opinion set forth below is qualified in its entirety by
reference to the full text of the opinion. STOCKHOLDERS ARE URGED TO READ
SALOMON SMITH BARNEY'S OPINION CAREFULLY AND IN ITS ENTIRETY.

    In arriving at its opinion, Salomon Smith Barney reviewed a draft of the
merger agreement and held discussions with senior officers, directors and other
representatives and advisors of Con Edison and senior officers and other
representatives and advisors of Northeast concerning the businesses, operations
and prospects of Con Edison and Northeast. Salomon Smith Barney examined
publicly available business and financial information relating to Con Edison and
Northeast (including Yankee) as well as financial forecasts and other
information and data for Con Edison and Northeast which were provided to or
otherwise discussed with Salomon Smith Barney by the managements of Con Edison
and Northeast, including information relating to strategic implications and
operational benefits anticipated to result from the merger. Salomon Smith Barney
reviewed and discussed with senior officers of Con Edison and Northeast the
financial terms of the merger as set forth in the merger agreement in relation
to, among other things:

    - current and historical market prices and trading volumes of the common
      stock of each of Con Edison and Northeast (including, specifically, recent
      prices and volumes);

    - the historical and projected earnings and other operating data of Con
      Edison and Northeast; and

    - the capitalization and financial condition of Con Edison and Northeast.

    Salomon Smith Barney considered, to the extent publicly available, the
financial terms of other similar transactions recently effected that Salomon
Smith Barney considered relevant in evaluating the merger and analyzed
financial, stock market and other publicly available information relating to the
businesses of other companies whose operations Salomon Smith Barney considered
relevant in evaluating those of Con Edison and Northeast. Salomon Smith Barney
also evaluated the pro forma financial impact of the merger on Con Edison. In
addition, Salomon Smith Barney conducted other analyses and examinations and
considered other information and financial, economic and market criteria as it
deemed appropriate in arriving at its opinion.

    In rendering its opinion, Salomon Smith Barney assumed and relied, without
independent verification, upon the accuracy and completeness of all financial
and other information and data publicly available or furnished to or otherwise
reviewed by or discussed with Salomon Smith Barney and further relied on the
assurances of management of Con Edison and Northeast that they were not aware of
any facts that would make any of that information inaccurate or misleading. With
respect to

                                       33
<PAGE>
financial forecasts and other information and data provided to or otherwise
reviewed by or discussed with it, Salomon Smith Barney was advised by the
managements of Con Edison and Northeast that the forecasts and other information
and data had been reasonably prepared on bases reflecting the best currently
available estimates and judgments of the respective managements of Con Edison
and Northeast as to the future financial performance of Con Edison and Northeast
and the strategic implications and operational benefits anticipated to result
from the merger. Salomon Smith Barney expressed no view with respect to the
forecasts and other information and data or the assumptions on which they were
based. Salomon Smith Barney assumed that the merger will be treated as tax-free
for federal income tax purposes. Salomon Smith Barney has not made or been
provided with an independent evaluation or appraisal of the assets or
liabilities, contingent or otherwise, of Con Edison or Northeast nor did Salomon
Smith Barney make any physical inspection of the properties or assets of Con
Edison or Northeast. Representatives of Con Edison advised Salomon Smith Barney,
and it assumed, that the final terms of the merger agreement would not vary
materially from those set forth in the draft reviewed by Salomon Smith Barney.
Salomon Smith Barney further assumed that the merger will be consummated in
accordance with the terms of the merger agreement, without waiver of any of the
conditions to the merger contained in the merger agreement.

    Salomon Smith Barney did not express any opinion as to what the value of the
New Con Edison common stock actually will be when issued in the merger or the
price at which the New Con Edison common stock will trade subsequent to the
merger. Salomon Smith Barney was not asked to consider, and its opinion does not
address, the relative merits of the merger as compared to any alternative
business strategies that might exist for Con Edison or the effect of any other
transaction in which Con Edison might engage. Salomon Smith Barney's opinion
necessarily was based on information available to it, and financial, stock
market and other conditions and circumstances existing and disclosed to Salomon
Smith Barney as of the date of the opinion.

    SALOMON SMITH BARNEY'S ADVISORY SERVICES AND OPINION WERE PROVIDED FOR THE
INFORMATION OF CON EDISON'S BOARD OF DIRECTORS IN ITS EVALUATION OF THE PROPOSED
MERGER AND DID NOT CONSTITUTE A RECOMMENDATION OF THE MERGER TO CON EDISON OR A
RECOMMENDATION TO ANY STOCKHOLDER AS TO HOW THAT STOCKHOLDER SHOULD VOTE ON ANY
MATTERS RELATING TO THE PROPOSED MERGER.

    In connection with rendering its opinion, Salomon Smith Barney made a
presentation to the Con Edison Board of Directors on October 12, 1999, with
respect to the material analyses performed by Salomon Smith Barney in evaluating
the fairness of the exchange ratio in the Con Edison merger. The following is a
summary of this presentation. The summary includes information presented in
tabular format. IN ORDER TO UNDERSTAND FULLY THE FINANCIAL ANALYSES USED BY
SALOMON SMITH BARNEY, THESE TABLES MUST BE READ TOGETHER WITH THE TEXT OF EACH
SUMMARY. THE TABLES ALONE DO NOT CONSTITUTE A COMPLETE DESCRIPTION OF THE
FINANCIAL ANALYSES. The following quantitative information, to the extent it is
based on market data, is, except as otherwise indicated, based on market data as
it existed at or prior to October 12, 1999 and is not necessarily indicative of
current or future market conditions.

    OVERVIEW AND VALUATION OF NORTHEAST

    Salomon Smith Barney included in its presentation to the Con Edison Board of
Directors an overview of Northeast, including historical financial and
historical trading price information concerning Northeast. Salomon Smith Barney
noted the $18.56 trading price of Northeast common shares on October 6, 1999,
the last full trading day prior to the time public reports appeared speculating
about discussions between Con Edison and Northeast.

    Salomon Smith Barney also performed, and summarized, analyses of the value
of Northeast common shares using three methodologies: a comparable public
companies analysis; a comparable transaction analysis; and discounted cash flow
analyses. Salomon Smith Barney performed discounted cash flow analyses both on a
consolidated basis, using data for all of Northeast, and on a sum-of-the-parts
basis, in which it applied the methodology separately to data for each component

                                       34
<PAGE>
business of Northeast, and, in each case, using both estimated cash flows based
on a regulated maximum return-on-equity, sometimes referred to as ROE, at
Northeast's subsidiary, The Connecticut Light and Power Company, of 10.3% and of
11.3%. Each of these analyses was used to generate a reference range for the
value of Northeast as of an assumed closing date of December 31, 2000.

    COMPARABLE PUBLIC COMPANIES ANALYSIS

    As part of its analysis, Salomon Smith Barney compared publicly available
financial, operating and stock market information and publicly available
consensus estimates of future earnings per share, sometimes referred to as EPS,
of Northeast with those of the following eleven publicly-traded electric utility
companies:

    - Allegheny Energy, Inc.

    - Conectiv

    - DQE, Inc.

    - FPL Group, Inc.

    - Energy East Corporation

    - NSTAR

    - PG&E Corporation

    - Potomac Electric Power Company

    - Sempra Energy

    - TECO Energy, Inc.

    - Wisconsin Energy Corporation

    Salomon Smith Barney considered these companies to be reasonably similar to
Northeast insofar as they participate in business segments similar to
Northeast's principal business segment, but noted that none of these companies
has the same management, makeup, size and combination of businesses as
Northeast.

    For Northeast and each of the comparable companies, Salomon Smith Barney
calculated and compared, among other things:

    - the ratio of the closing share price on October 8, 1999, the last full
      trading day prior to the preparation of the presentation, to:

       - 1999 earnings per share estimates and

       - 2000 earnings per share estimates; and

    - the ratio of equity value to book value as of June 30, 1999.

    The following table sets forth the results of these calculations.

</TABLE>

    Salomon Smith Barney applied qualitative judgments to these ranges to derive
an implied value per Northeast common share as of the date of its analysis
ranging from $18.50 to $22.25. Salomon Smith Barney then calculated an estimated
range of value per share as of December 31, 2000, the assumed closing date for
purposes of its analysis, by accruing the range of implied value as of the date
of its analysis at a rate of 6.4% per year. The rate of 6.4% was selected based
on Northeast's estimated cost of equity of 8.6% less Northeast's current
dividend yield of 2.2%. This resulted in an implied value per Northeast common
share as of December 31, 2000 ranging from $20.50 to $24.50.

    COMPARABLE TRANSACTIONS ANALYSIS

    Salomon Smith Barney analyzed publicly available financial, operating and
stock market information for twelve selected merger and acquisition transactions
in the electric utility industry announced since early 1998. The precedent
transactions reviewed were:

</TABLE>

    Salomon Smith Barney considered the precedent transactions to be reasonably
similar to the merger, but none of these transactions is identical to the
merger.

    For each of the precedent transactions, Salomon Smith Barney derived, among
other things:

    - the premium of the transaction consideration to:

       - closing price of the acquired stock one day prior to announcement of
         the transaction,

       - closing price of the acquired stock 5 trading days prior to
         announcement of the transaction and

       - closing price of the acquired stock one month prior to announcement of
         the transaction;

    - the ratio of the implied equity value to:

       - estimated earnings per share for the fiscal year following announcement
         of the transaction and

       - estimated earnings per share for the second fiscal year following
         announcement of the transaction; and

    - the ratio of equity value to book value.

    The following table sets forth the results of these calculations.

</TABLE>

    Salomon Smith Barney applied qualitative judgments to these ranges to derive
an implied value per Northeast common share as of the date of its analysis
ranging from $22.75 to $26.50. Salomon Smith Barney then calculated an estimated
range of value per share as of December 31, 2000, the

                                       36
<PAGE>
assumed closing date for purposes of its analysis, by accruing the range of
implied value as of the date of its analysis at a rate of 6.4% per year. The
rate of 6.4% was selected based on Northeast's estimated cost of equity of 8.6%
less Northeast's current dividend yield of 2.2%. This resulted in an implied
value per Northeast common share as of December 31, 2000 ranging from $24.75 to
$28.75.

    DISCOUNTED CASH FLOW ANALYSIS--CONSOLIDATED

    Salomon Smith Barney also performed a discounted cash flow analysis of
Northeast using Northeast management projections for the years 2001 through
2005, as adjusted by Con Edison management. Salomon Smith Barney calculated the
estimated present value of Northeast's projected unlevered free cash flows for
the years 2001 through 2005, in one analysis with The Connecticut Light and
Power Company's return on equity capped at 10.3% and in another with it capped
at 11.3%. Salomon Smith Barney added to that the present value of the estimated
market value as of the end of 2005 of Northeast's capitalization. This estimated
market value as of the end of 2005 was calculated by multiplying Northeast's
projected 2005 net income by a range of 13.0x to 14.0x, which range was based on
the comparable companies analysis described above, and adding to that product
the book value of the other elements of Northeast's capitalization as of the end
of 2005. The cash flows for 2001 through 2005 and the estimated market value as
of the end of 2005 were both discounted at rates ranging from 6.6% to 6.8%,
which was Salomon Smith Barney's estimate of the weighted average cost of
capital of Northeast and the comparable companies listed under the comparable
companies analysis above. This analysis assumed that the merger would close on
December 31, 2000 and provided an estimate of value as of that date. From this
analysis, Salomon Smith Barney derived a range of implied equity value per
Northeast common share of $27.00 to $29.00, with a 10.3% cap on The Connecticut
Light and Power Company's return on equity, and $28.00 to $30.25, with an 11.3%
cap on that return on equity.

    DISCOUNTED CASH FLOW ANALYSIS--SUM-OF-THE-PARTS

    Salomon Smith Barney also performed a sum-of-the-parts discounted cash flow
analysis of Northeast using Northeast management projections for each of the
component businesses for the years 2001 through 2005, as adjusted by Con Edison
management. Salomon Smith Barney calculated the estimated present value of the
projected unlevered free cash flows of each business for the years 2001 through
2005, in one analysis with The Connecticut Light and Power Company's return on
equity capped at 10.3% and in another with it capped at 11.3%, and the estimated
present value of the projected market value of the capitalization attributable
to each business at the end of the year 2005. For purposes of this analysis,
Salomon Smith Barney calculated the estimated market value as of the end of 2005
(2003 in the case of Select Energy, Inc.) of the capitalization of each of
Northeast's businesses, using ranges of ratios that Salomon Smith Barney
believed were appropriate for each business. These estimated values, and the
relevant projected cash flows for each of Northeast's businesses, were then
discounted at rates that Salomon Smith Barney believed were appropriate for each
business. Northeast's regulated businesses analyzed included Northeast's
transmission and distribution business, encompassing The Connecticut Light and
Power Company, Western Massachusetts Electric Company and Public Service Company
of New Hampshire. The regulated businesses also included Yankee and Northeast's
other regulated businesses, encompassing Northeast/ parent, North Atlantic
Energy Corp., Holyoke Water Power Co., Northeast Nuclear Energy Co., Northeast
Utilities Service Co. and Rocky River Realty Co. For these businesses, other
than Yankee, Salomon Smith Barney used the same ratios for calculating estimated
market value of capitalization as of the end of 2005 and the same discount rates
as those used in the consolidated discounted cash flow analysis described above.
For Yankee, Salomon Smith Barney used ratios of price to projected year 2005 net
income attributable to Yankee ranging from 16.3x to 17.8x, which range was based
on Salomon Smith Barney's review of publicly available financial, operating and
stock market information and publicly available consensus estimates of future
earnings per share of four comparable publicly-traded gas distribution companies
in the Northeast, to which Salomon Smith Barney added the book value of the
other components of Yankee's capitalization to arrive at the estimated market
value as of

                                       37
<PAGE>
the end of 2005 of the capitalization of Yankee. Salomon Smith Barney then
discounted this estimated market value and the relevant projected cash flows at
rates ranging from 7.4% to 7.6%, which was Salomon Smith Barney's estimate of
the weighted average cost of capital of the four gas distribution companies in
the Northeast. Salomon Smith Barney calculated the estimated value as of the end
of 2005 attributable to Northeast's generation and service businesses by
multiplying the projected earnings before interest, taxes, depreciation and
amortization, sometimes referred to as EBITDA, in 2005 attributable to those
businesses by a range of 7.25x to 7.75x, which range was based on Salomon Smith
Barney's review of publicly available financial, operating and stock market
information and publicly available consensus estimates of future earnings per
share of four publicly-traded electric generation companies, as adjusted by
Salomon Smith Barney to reflect its judgment of the anticipated lack of
comparability of Northeast's generation and service business in 2005 to those
companies. Salomon Smith Barney then discounted this estimated value and the
relevant projected cash flows at rates ranging from 7.1% to 7.4%, which was
Salomon Smith Barney's estimate of the weighted average cost of capital of the
four electric generation companies. Salomon Smith Barney calculated the
estimated value as of the end of 2005 attributable to Select Energy and HEC,
Inc., two of Northeast's unregulated businesses, by multiplying the projected
EBITDA in 2005 (2003 in the case of Select Energy) attributable to those
businesses by a range of 8.0x to 8.5x. Salomon Smith Barney then discounted this
estimated value and the relevant cash flows at rates ranging from 10.5% to
11.5%. The ranges for this multiplication and discounting were selected by
Salomon Smith Barney using its qualitative judgment, based on its experience
generally, in light of the lack of sufficiently comparable companies for this
analysis. The following table sets forth the results of these analyses.

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

* The Connecticut Light and Power Company's return on equity varied from 10.3%
    in one analysis to 11.3% in the other.

    This analysis assumed that the merger would close on December 31, 2000 and
provided an estimate of value as of that date. Salomon Smith Barney also reduced
these estimated implied per share values by approximately $0.50 per share to
account for adjustments anticipated by Con Edison management. Based on this
analysis, Salomon Smith Barney derived a range of implied equity value per
Northeast common share ranging from $22.00 to $24.00, with The Connecticut
Light and Power Company's return on equity capped at 10.3%, and $23.25 to
$25.25, with it capped at 11.3%.

    SYNERGIES

    Salomon Smith Barney reviewed estimates of revenue and cost synergies.
Salomon Smith Barney then estimated the present value as of an assumed closing
date of December 31, 2000 of the projected streams of after-tax cash flows
generated by those synergies, net of estimated implementation costs for
synergies for the regulated businesses and unregulated businesses. For the
regulated businesses, Salomon Smith Barney discounted the after-tax cash flows
from the projected synergies at rates reflecting the weighted average cost of
capital for Northeast and its comparable companies listed under the comparable
companies analysis above, which ranged from 6.6% to 6.8%. While there is no way
to predict the outcome of the regulatory approval process, Salomon Smith Barney
conservatively assumed for purposes of its analysis that as much as 50% of the
benefits of the projected synergies in the

                                       38
<PAGE>
regulated businesses for the first five years after the merger would be shared
with customers of New Con Edison and thereafter as much as 100% of those
benefits would be retained by the customers of New Con Edison. For the
unregulated businesses, and solely for purposes of this analysis, Salomon Smith
Barney discounted the after-tax cash flows from the projected synergies at
higher rates, which ranged from 10.5% to 11.5%. Salomon Smith Barney assumed for
purposes of its analysis that 100% of the benefits of the projected synergies in
the unregulated businesses would be retained by New Con Edison. Based on this
analysis, Salomon Smith Barney derived a range of incremental values per
Northeast common share from the estimated synergies ranging from approximately
$1.75 to $2.00.

    OVERVIEW AND VALUATION OF CON EDISON

    Salomon Smith Barney included in its presentation to the Con Edison Board of
Directors an overview of Con Edison, including historical financial information
and historical trading price information on Con Edison. Salomon Smith Barney
noted the $41.81 trading price of Con Edison common shares on October 6, 1999,
the last full trading day prior to the time public reports appeared speculating
about discussions between Con Edison and Northeast.

    Salomon Smith Barney also performed, and summarized, analyses of the value
of Con Edison common shares using two methodologies: a comparable public
companies analysis and a discounted cash flow analysis, which, in the case of
the valuation of Con Edison, was done only on a consolidated basis, using data
for all of Con Edison. Each of these analyses was used to generate a reference
range for the value of Con Edison common shares as of an assumed closing date of
December 31, 2000.

    COMPARABLE PUBLIC COMPANIES ANALYSIS

    Salomon Smith Barney compared publicly available financial, operating and
stock market information and publicly available consensus estimates of future
earnings per share of Con Edison with those of the same eleven publicly-traded
electric utility companies as described above for the Comparable Public
Companies analysis of Northeast.

    Salomon Smith Barney considered these companies to be reasonably similar to
Con Edison insofar as they participate in business segments similar to Con
Edison's principal business segment, but noted that none of these companies has
the same management, makeup, size and combination of businesses as Con Edison.

    For each of the comparable companies, Salomon Smith Barney calculated and
compared, among other things:

    - the ratio of the closing stock price on October 8, 1999, the last full
      trading day prior to the preparation of the presentation, to:

       - 1999 earnings per share estimates and

       - 2000 earnings per share estimates; and

    - the ratio of equity value to book value as of June 30, 1999.

    The following table sets forth the results of these calculations.

</TABLE>

    Salomon Smith Barney applied qualitative judgments to these ranges to derive
an implied value per Con Edison common share as of the date of its analysis
ranging from $38.75 to $45.25. Salomon Smith Barney then calculated an estimated
range of value per share as of December 31, 2000, the

                                       39
<PAGE>
assumed closing date, by accruing the range of implied value as of the date of
its analysis at a rate of 3.5% per year. The rate of 3.5% was selected based on
Con Edison's estimated cost of equity of 8.6% less Con Edison's current dividend
yield of 5.1%. This resulted in an implied value per Con Edison common share as
of December 31, 2000 ranging from $40.50 to $47.00.

    DISCOUNTED CASH FLOW ANALYSIS

    Salomon Smith Barney also performed a discounted cash flow analysis of Con
Edison. Salomon Smith Barney calculated the estimated present value of Con
Edison's projected unlevered free cash flows for the years 2001 through 2005.
Salomon Smith Barney added to that the present value of the estimated market
value as of the end of 2005 of Con Edison's capitalization. This estimated
market value as of the end of 2005 was calculated by multiplying Con Edison's
projected 2005 net income by a range of 13.0x to 14.0x, which range was based on
the comparable companies analysis described above, and adding to that product
the book value of the other elements of Con Edison's capitalization as of the
end of 2005. The cash flows for 2001 through 2005 and the estimated market value
as of the end of 2005 were both discounted at rates ranging from 6.6% to 6.8%,
which was Salomon Smith Barney's estimate of the weighted average cost of
capital of Con Edison and the comparable companies used for the comparable
companies analysis described above. This analysis assumed that the merger would
close on December 31, 2000 and provided an estimate of value as of that date.
From this analysis, Salomon Smith Barney derived a reference range of implied
value per Con Edison common share of approximately $40.00 to $42.75.

    PRO FORMA COMBINATION ANALYSIS

    Salomon Smith Barney reviewed the pro forma impact of the merger on Con
Edison's earnings per share and other financial ratios for the fiscal years
ended 2001 through 2003. In performing this analysis, Salomon Smith Barney
utilized Northeast management projections, as adjusted by Con Edison management,
for Northeast and Con Edison management projections for Con Edison and assumed
the merger would close on December 31, 2000 for $26.50 per Northeast share,
payable 50% in cash and 50% in stock. Salomon Smith Barney also assumed that the
estimated revenue and cost synergies provided by Con Edison and Northeast
managements would be achieved, subject to the sharing assumption set forth above
under "--Synergies." The analysis was performed assuming different closing
prices for Con Edison's shares at the consummation of the merger to provide a
sensitivity analysis reflecting the impact of the potentially differing number
of shares to be issued in the merger. Based upon this analysis, the merger would
be dilutive to earnings in 2001, with dilution ranging from $0.35 per share to
$0.19 per share; modestly dilutive or accretive to earnings in 2002, ranging
from dilution of $0.12 per share to accretion of $0.06 per share; and accretive
to earnings in 2003, with accretion ranging from $0.06 per share to $0.25 per
share. Based upon this analysis, Salomon Smith Barney also noted that the merger
would have a limited impact on certain of Con Edison's financial ratios. Salomon
Smith Barney determined that the merger would result in a limited increase in
the ratio of total debt to total capitalization in each of 2001, 2002 and 2003;
a limited decrease in the ratio of funds from operations to total debt in each
of 2001 and 2002 and a limited increase in the ratio of funds from operations to
total debt in 2003; a limited decrease in the ratio of EBITDA to net interest in
each of 2001, 2002 and 2003; and a limited decrease in the ratio of funds from
operations to net interest in each of 2001 and 2002 and a limited increase in
the ratio of funds from operations to net interest in 2003. Salomon Smith Barney
also performed an analysis of the potential impact of the merger on Con Edison's
credit rating. The analysis concluded that, although Con Edison's credit rating
would remain investment grade, the merger could have a negative impact.

    The preceding discussion is a summary of the material financial analyses
furnished by Salomon Smith Barney to the Con Edison Board of Directors but it
does not purport to be a complete description of the analyses performed by
Salomon Smith Barney or of its presentations to the Con Edison Board of
Directors. The preparation of financial analyses and fairness opinions is a
complex

                                       40
<PAGE>
process involving subjective judgments and is not necessarily susceptible to
partial analysis or summary description. Salomon Smith Barney made no attempt to
assign specific weights to particular analyses or factors considered, but rather
made qualitative judgments as to the significance and relevance of all the
analyses and factors considered and determined to give its fairness opinion as
described above. Accordingly, Salomon Smith Barney believes that its analyses,
and the summary set forth above, must be considered as a whole, and that
selecting portions of the analyses and of the factors considered by Salomon
Smith Barney, without considering all of the analyses and factors, could create
a misleading or incomplete view of the processes underlying the analyses
conducted by Salomon Smith Barney and its opinion. With regard to the comparable
companies analyses summarized above, Salomon Smith Barney selected comparable
public companies on the basis of various factors, including the size of the
public company and similarity of the line of business; however, no public
company used as a comparison in these analyses, and no transaction used as a
comparison in the comparable transaction analysis summarized above, is identical
to Con Edison or Northeast, any business segment of Northeast or the merger. As
a result, these analyses are not purely mathematical, but also take into account
differences in financial and operating characteristics of the comparable
companies and other factors that could affect the transaction or public trading
value of the comparable companies and transactions to which Con Edison and
Northeast, the business segments of Northeast and the merger are being compared.

    In its analyses, Salomon Smith Barney made numerous assumptions and
considered a number of factors with respect to Con Edison, Northeast (including
Northeast's planned acquisition of Yankee and the planned divestiture of
Northeast's nuclear assets), industry performance, general business, economic,
market and financial conditions and other matters, many of which are beyond the
control of Con Edison and Northeast. Any estimates contained in Salomon Smith
Barney's analyses are not necessarily indicative of actual values or predictive
of future results or values, which may be significantly more or less favorable
than those suggested by these analyses. Estimates of values of companies do not
purport to be appraisals or necessarily to reflect the prices at which companies
may actually be sold. Because these estimates are inherently subject to
uncertainty, none of Con Edison, Northeast, the Con Edison Board of Directors,
Salomon Smith Barney or any other person assumes responsibility if future
results or actual values differ materially from the estimates.

    Salomon Smith Barney's analyses were prepared solely as part of Salomon
Smith Barney's analysis of the fairness of the exchange ratio in the Con Edison
merger and were provided to the Con Edison Board of Directors in that
connection. The exchange ratio and the other terms of the merger agreement were
determined through arm's-length negotiations between Con Edison and Northeast
and were approved by Con Edison's Board. Salomon Smith Barney provided advice to
Con Edison during the course of those negotiations, but Salomon Smith Barney did
not determine the exchange ratio or recommend any specific exchange ratio to Con
Edison. The opinion of Salomon Smith Barney was only one of the factors taken
into consideration by the Con Edison Board of Directors in making its
determination to approve the merger agreement and the merger. See "The
Merger--Con Edison's Reasons for the Merger and the Con Edison Board of
Directors Recommendation" on page 30.

    Salomon Smith Barney is an internationally recognized investment banking
firm engaged, among other things, in the valuation of businesses and their
securities in connection with mergers and acquisitions, restructurings,
leveraged buyouts, negotiated underwritings, competitive biddings, secondary
distributions of listed and unlisted securities, private placements and
valuations for estate, corporate and other purposes. Con Edison selected Salomon
Smith Barney to act as its financial advisor on the basis of Salomon Smith
Barney's international reputation. Salomon Smith Barney and its predecessors and
affiliates had previously rendered investment banking services to Con Edison and
Northeast unrelated to the merger, for which Salomon Smith Barney has received
customary compensation. In the ordinary course of its business, Salomon Smith
Barney and its affiliates may actively trade or hold the securities of both Con
Edison and Northeast for their own account and for the account of customers and,
accordingly, may at any time hold a long or short position in these

                                       41

securities. Salomon Smith Barney and its affiliates, including Citigroup Inc.
and its affiliates, may maintain other business relationships with Con Edison
and Northeast and their respective affiliates.

    Pursuant to Salomon Smith Barney's engagement letter, Con Edison has agreed
to pay Salomon Smith Barney for its services rendered in connection with the
merger, fees based on the total amount of cash and the fair market value of all
other consideration paid or payable to Northeast's shareholders in connection
with the merger. The aggregate amount of the fees is estimated to be between
$10.9 million and $11.4 million. Of the fees payable to Salomon Smith Barney in
connection with the merger, $250,000 became payable when Con Edison and
Northeast commenced substantive negotiations relating to the merger, $2,250,000
became payable upon execution of the merger agreement, $2,500,000 will become
payable upon approval of the merger by the shareholders of Con Edison and
Northeast and the remainder will become payable upon closing. In addition, if
Con Edison receives any termination fee under the terms of the merger agreement,
one-half of such fee, net of Con Edison's out-of-pocket expenses in connection
with the proposed merger, will be payable to Salomon Smith Barney up to a
maximum of one-half of the amount of the aggregate fees payable to Salomon Smith
Barney for a completed merger, as described above. Con Edison has also agreed to
reimburse Salomon Smith Barney for its reasonable travel and other out-of-pocket
expenses incurred in connection with its engagement, including the reasonable
fees and disbursements of its counsel, and to indemnify Salomon Smith Barney
against specific liabilities and expenses relating to or arising out of its
engagement, including liabilities under the federal securities laws.

NORTHEAST'S REASONS FOR THE MERGER

    The Northeast Board of Trustees believes that the merger will join two
well-managed companies with complementary and contiguous operations as well as a
shared vision of the future of the energy markets in the Northeast. The
Northeast Board of Trustees has concluded that the merger will allow it to
achieve its strategic goals discussed in "--Background to the Merger" to focus
its regulated subsidiaries on energy distribution and its unregulated
subsidiaries on energy marketing and generation by giving the combined company
the increased scale of operations and customer base necessary to compete in
those markets. Based on the prospects of utility deregulation and the increasing
competitive pressure faced by electric and gas utility companies, the Northeast
Board of Trustees believes that, in order to succeed in such a market, Northeast
must have a larger customer base with increased economies of scale to be an
efficient, low cost supplier of energy and related services. For the reasons
stated above and in "--Background to the Merger," the Northeast Board of
Trustees has concluded that a merger with a larger partner like Con Edison is
superior to remaining an independent company and growing solely through
acquisitions. In that regard, the Northeast Board of Trustees believes that the
merger will result in the greatest overall value to its shareholders as well as
to employees and customers of Northeast and its subsidiaries, while creating the
size and scale necessary to be successful in a restructured energy market. The
Northeast Board of Trustees believes that benefits resulting from the merger
include:

    - IMPROVED STRATEGIC POSITION AND INCREASED DISTRIBUTION ASSETS AND CUSTOMER
      BASE:  The merger will create one of the leading electric and gas
      transmission and distribution companies, in terms of number of customers,
      in the country and provide a strong regional foundation with the expanded
      scale and scope necessary to be an effective participant in the emerging
      and increasingly competitive energy markets. The combined company will be
      the nation's largest

                                       42
<PAGE>
      electric distribution utility with over 5,000,000 electric customers and
      over 1.4 million natural gas customers.

    - INCREASED FINANCIAL STRENGTH:  The combined company will be substantially
      stronger financially than Northeast, with revenues on a pro forma basis of
      approximately $11 billion dollars and a total enterprise value of $19
      billion dollars. This financial strength will provide significant benefits
      to Northeast's regulated and unregulated businesses.

    - POTENTIAL EXPANSION OPPORTUNITIES:  The combined company's larger customer
      base and distribution channels will allow it to offer additional products
      and services. The merger will create a company that will be able to offer
      integrated energy products and services and telecommunications products
      and services.

    - POTENTIAL SYNERGIES:  Neighboring service territories, including the
      largest customer base in both the New York and New England power pools,
      will allow the combined company to take advantage of operating
      efficiencies, economies of scale and cross-selling opportunities resulting
      in the possibility of merger savings (net of the costs to achieve such
      savings) in regulated businesses approximately equal to $1.3 billion over
      ten years. In addition, by integrating management, the larger company will
      be able to draw on a larger and more diverse pool of talent while allowing
      for the elimination of duplicate corporate and administrative functions.
      The Board's conclusion that the merger will result in potential synergies
      was based in part upon an analysis of potential synergies resulting from a
      merger of Northeast and Con Edison that was jointly prepared by the
      managements of Northeast and Con Edison with the assistance of an outside
      consultant retained by the two companies. For a more detailed description
      of the synergies analysis, see "--Con Edison's Reasons for the Merger and
      the Con Edison Board of Directors Recommendation."

    - PREMIUM OVER MARKET PRICE:  Northeast shareholders will receive
      approximately $25 in value per Northeast share, subject to adjustment, to
      be paid either in cash, shares of New Con Edison stock or a combination of
      the two, which represents an approximate 36% premium over the October 6,
      1999 closing price of Northeast common shares, the last full trading day
      prior to the time public reports appeared speculating about discussions
      between Con Edison and Northeast (or a 44% premium if Northeast satisfies
      the divestiture condition and the closing occurs on December 31, 2000). In
      addition, Northeast shareholders who receive new Con Edison shares will
      receive an increase in their quarterly dividend, based on Con Edison's and
      Northeast's respective current dividend policies. See "The
      Merger--Dividends."

    In approving the merger, the Northeast Board of Trustees consulted with
Northeast management as well as its outside legal counsel and financial
advisors, and considered a number of factors, including the following factors:

    - the risks associated with continuing to execute Northeast's strategic plan
      as an independent entity and the potential rewards associated with the
      merger. These risks include, among others, the risks associated with
      remaining independent amidst industry-wide restructuring and
      consolidation, and the rewards include, among others, the substantial
      value to be paid or delivered in the merger to the Northeast shareholders
      and the ability of existing Northeast shareholders to partake in the
      potential future growth and profitability of New Con Edison;

    - Northeast's consideration of possible acquisitions of or business
      combinations or joint ventures with entities other than Con Edison and the
      conclusion of the Northeast Board of Trustees, based on such
      considerations, that the merger with Con Edison is more feasible and is
      expected to yield greater benefits to Northeast shareholders, customers
      and employees, than the alternatives previously considered by Northeast;

    - the value to be received by holders of Northeast common shares provided
      for in the merger agreement, which represents a 44% premium over the
      closing market price of Northeast

                                       43
<PAGE>
      common shares as of October 6, 1999, the last full trading day prior to
      the time public reports appeared speculating about discussions between Con
      Edison and Northeast, including the additional value to be received if
      Northeast satisfies the divestiture condition and the additional value to
      be received if the closing occurs on December 31, 2000, relative to the
      stock price premiums paid in similar mergers in the electric utility
      industry, and that Northeast's shareholders would hold approximately 18%
      (subject to adjustment) of the outstanding stock of New Con Edison after
      the merger;

    - the review and analysis of each of Con Edison's and Northeast's business,
      financial condition, earnings, risks and prospects;

    - historical market prices and trading information with respect to the Con
      Edison common shares and Northeast common shares;

    - comparisons of historical financial measures for Northeast and Con Edison,
      including earnings, return on capital and cash flow, and comparisons of
      historical operational measures for Northeast and Con Edison;

    - current industry, economic and market conditions and the prospects of
      further restructuring and consolidation in the electric and gas utility
      industries;

    - the ability to complete the merger as a tax-free transaction for U.S.
      federal income tax purposes and to have the conversion of Northeast common
      shares be tax-free to shareholders to the extent their shares are
      converted into New Con Edison common stock;

    - the expectation of synergies from the transaction resulting in cost
      savings and other benefits over time based in part upon an analysis that
      was jointly prepared by the managements of Northeast and Con Edison with
      the assistance of an outside consultant;

    - the possibility that varying levels of cost savings in respect of the
      regulated businesses achievable from the merger over time would be shared
      with customers of the regulated businesses of New Con Edison;

    - the terms and conditions of the merger agreement, one of which provides
      the Board of Trustees of Northeast the right to terminate the merger
      agreement prior to its approval by Northeast shareholders in the exercise
      of its fiduciary duty in connection with a superior proposal, and the
      potential termination and expense reimbursement fees payable by Northeast;

    - the proposed composition of senior management and the Board of Directors
      of New Con Edison;

    - the analyses, presentations and opinions of Morgan Stanley & Co.
      Incorporated and SG Barr Devlin, to the effect that, as of October 12,
      1999, and based upon and subject to the various assumptions and
      limitations set forth in their respective opinions, the consideration
      proposed to be received by Northeast shareholders pursuant to the merger
      agreement was fair, from a financial point of view, to the Northeast
      shareholders (the written opinions of Morgan Stanley & Co. Incorporated
      and SG Barr Devlin dated as of the date of this joint proxy statement/
      prospectus reconfirming the opinions dated October 12, 1999 are attached
      as Annexes C and D to this joint proxy statement/prospectus);

    - the benefits to Northeast's shareholders, customers and employees
      resulting from the fact that, although New Con Edison's corporate
      headquarters will be located in New York City, the headquarters for the
      operations in New England of the service company and for New Con Edison's
      unregulated businesses will be in Connecticut and that Northeast's
      subsidiaries will continue to maintain offices for utility operations in
      Connecticut, Massachusetts and New Hampshire;

    - the potential benefit to Northeast's employees from the expanded
      opportunities available as part of a much larger organization;

                                       44
<PAGE>
    - that Northeast's customers should benefit from the operations of
      Northeast's utility subsidiaries remaining substantially unchanged while
      having available to them the increased financial strength and potential
      synergies resulting from the merger;

    - that while the merger is likely to be completed, there are risks
      associated with obtaining necessary regulatory approvals, and as a result
      of other conditions to the completion of the merger, it is possible that
      the merger may not be completed even if approved by shareholders;

    - that the residents of the states and municipalities served by Northeast's
      utility subsidiaries will benefit from the shared commitment of Con Edison
      and Northeast to environmental concerns;

    - the impact of regulations under various state and federal laws, including
      the additional regulatory oversight that would result from the addition of
      public utility operations in New Jersey, Pennsylvania and New York, and
      the issues involved in the registration of New Con Edison as a holding
      company under the Public Utility Holding Company Act;

    - restrictions on the conduct of business by Northeast during the period
      before the completion of the merger;

    - the problems inherent in merging the operations of two large companies,
      including the possibility that management may be distracted from regular
      business concerns by the need to integrate operations, unforeseen
      difficulties in integrating operations and systems, problems assimilating
      and retaining employees and potential adverse short-term effects on
      operating results of the combined company; and

    - the interests that certain executive officers and trustees of Northeast
      may have with respect to the merger in addition to their interests as
      shareholders of Northeast generally.

    The Northeast Board of Trustees believed that, overall, the potential
benefits of the merger to Northeast and its shareholders outweighed the risks.

    This discussion of the information and factors considered by the Northeast
Board of Trustees in making its decision is not intended to be exhaustive but is
believed to include all material factors considered by the Northeast Board of
Trustees. In view of the wide variety of factors considered in connection with
its evaluation of the merger and the complexity of these matters, the Northeast
Board of Trustees did not find it useful to and did not attempt to quantify,
rank or otherwise assign relative weights to these factors. The Northeast Board
of Trustees relied on the experience and expertise of its financial advisors,
Morgan Stanley and SG Barr Devlin, for quantitative analyses of the financial
terms of the merger. In addition, the Northeast Board of Trustees did not
undertake to make any specific determination as to whether any particular
factor, or any aspect of any particular factor, was favorable or unfavorable to
its ultimate determination, but rather the Northeast Board of Trustees conducted
an overall analysis of the factors described above, including through
discussions with and questioning of Northeast's management and legal, financial
and accounting advisors. In addition, individual members of the Northeast Board
of Trustees may have given different weight to different factors.

OPINIONS OF NORTHEAST'S FINANCIAL ADVISORS

    MORGAN STANLEY

    Pursuant to letter agreements dated as of September 15, 1998 and
September 14, 1999, Morgan Stanley was engaged to provide financial advisory
services and a financial fairness opinion in connection with the merger. Morgan
Stanley was selected by Northeast's Board of Trustees to act as Northeast's
financial advisor based on Morgan Stanley's qualifications, expertise,
reputation and its knowledge of the business and affairs of the electric utility
industry generally. At a meeting of Northeast's Board of Trustees on
October 12, 1999, Morgan Stanley rendered its oral opinion, subsequently
confirmed in writing, and delivered its written opinion dated as of the date of
this joint proxy statement/prospectus, that as of the dates of such opinions,
and based upon and subject to the various considerations noted in the opinions,
the consideration to be received by the holders of Northeast common shares
pursuant to the merger agreement was fair from a financial point of view to such
holders.

    THE FULL TEXT OF THE WRITTEN OPINION OF MORGAN STANLEY DATED THE DATE OF
THIS JOINT PROXY STATEMENT/PROSPECTUS, WHICH SETS FORTH, AMONG OTHER THINGS, THE
ASSUMPTIONS MADE, PROCEDURES FOLLOWED, MATTERS CONSIDERED AND LIMITATIONS ON THE
SCOPE OF REVIEW UNDERTAKEN BY MORGAN STANLEY IN RENDERING ITS OPINION IS
ATTACHED AS ANNEX C TO THIS JOINT PROXY STATEMENT/PROSPECTUS. NORTHEAST
SHAREHOLDERS ARE URGED TO, AND SHOULD, READ THE OPINION CAREFULLY AND IN ITS
ENTIRETY. MORGAN STANLEY'S OPINION IS DIRECTED TO NORTHEAST'S BOARD OF TRUSTEES
AND ADDRESSES ONLY THE FAIRNESS FROM A FINANCIAL POINT OF VIEW OF THE
CONSIDERATION TO BE RECEIVED BY THE HOLDERS OF NORTHEAST COMMON SHARES PURSUANT
TO THE MERGER AGREEMENT, AS OF THE DATE OF THE OPINION. MORGAN STANLEY'S OPINION
DOES NOT ADDRESS ANY OTHER ASPECT OF THE MERGER AND DOES NOT CONSTITUTE A
RECOMMENDATION TO ANY HOLDER OF NORTHEAST COMMON SHARES AS TO HOW TO VOTE AT THE
NORTHEAST SPECIAL MEETING. THE SUMMARY OF THE OPINION OF MORGAN STANLEY SET
FORTH IN THIS JOINT PROXY STATEMENT/PROSPECTUS IS QUALIFIED IN ITS ENTIRETY BY
REFERENCE TO THE FULL TEXT OF SUCH OPINION.

    In connection with rendering its opinions, Morgan Stanley, among other
things:

    - reviewed publicly available financial statements and other information of
      Northeast and Con Edison;

    - reviewed internal financial statements and other financial and operating
      data concerning Northeast and Con Edison prepared by the management of
      Northeast and Con Edison, respectively;

    - reviewed financial projections prepared by the management of Northeast and
      Con Edison;

    - discussed the past and current operations and financial condition and the
      prospects of Northeast and Con Edison, including the strategic rationale
      for the merger and information relating to strategic, financial and
      operational benefits anticipated from the merger with senior executives of
      Northeast and Con Edison, respectively;

    - reviewed the pro forma impact of the merger on Con Edison's earnings per
      share;

    - reviewed the reported prices and trading activity for the Northeast common
      shares and the common stock of Con Edison;

    - analyzed the effects on Northeast of its proposed acquisition of Yankee;

    - analyzed the effects on Northeast of the potential divestiture of two of
      its nuclear powered generation units, Millstone Units 2 and 3;

                                       46
<PAGE>
    - compared the financial performance of Northeast and Con Edison and the
      prices and trading activity of the Northeast common shares and the common
      stock of Con Edison with that of other comparable publicly-traded
      companies and their securities;

    - reviewed the financial terms, to the extent publicly available, of
      comparable acquisition transactions;

    - participated in discussions and negotiations among representatives of
      Northeast and Con Edison and their financial and legal advisors;

    - reviewed the merger agreement and related documents; and

    - performed such other analyses and considered such other factors as Morgan
      Stanley has deemed appropriate.

    In rendering its opinions, Morgan Stanley assumed and relied upon without
independent verification the accuracy and completeness of the information
reviewed by it for the purposes of its opinions. With respect to the financial
projections, and information relating to strategic, financial and operational
benefits anticipated from the merger, Morgan Stanley assumed that they were
reasonably prepared on bases reflecting the best currently available estimates
and judgments of the future financial performance of Northeast and Con Edison.
In addition, Morgan Stanley has assumed that the merger will be consummated in
accordance with the terms set forth in the merger agreement. Morgan Stanley has
not made any independent valuation or appraisal of the assets or liabilities of
Northeast, nor has it been furnished with any such appraisals. Morgan Stanley's
opinions were necessarily based on financial, economic, market and other
conditions as in effect on, and the information made available to it as of the
dates of its opinions. Morgan Stanley noted that it is not a legal or regulatory
expert and has relied upon, without independent verification, the assessment of
Northeast's legal and regulatory advisors with respect to the legal and
regulatory matters related to the merger.

    The following is a brief summary of analyses performed by Morgan Stanley in
the preparation of its oral opinion and the preparation of its opinion dated
October 12, 1999 and reviewed with the Northeast Board of Trustees on
October 12, 1999. Some of these summaries of financial analyses include
information presented in a tabular format. In order fully to understand the
financial analyses used by Morgan Stanley, the tables must be read together with
the text of each summary. The tables alone do not constitute a complete
description of the financial analyses.

    COMPARATIVE STOCK PRICE PERFORMANCE

    Morgan Stanley reviewed the recent stock price performance of Northeast and
Con Edison and compared such performance with that of the following indices:

    - Standard & Poor's Electric Utility Index

    - 30-year U.S. Treasury Bond yield

The Standard & Poor's Electric Utility Index represents the stock price
performance of a group of companies in the electric utility industry and is a
benchmark against which the stock price performance of Con Edison and Northeast
may be compared. Companies in the electric utility industry tend to have higher
than average leverage ratios and the common stock of these companies tends to
exhibit relatively high dividend yields. The stock price performance of these
companies may therefore be influenced to a high degree by movements in U.S.
Treasury yields. The purpose of the comparative stock price performance analysis
is to isolate the stock price performance of Con Edison and Northeast from
general stock market movements.

    The following table presents the change in value for these indices, as
compared to the change in the share prices of Northeast common shares and Con
Edison common shares over the period from

noted that October 6, 1999 was the last full trading day prior to the time
public reports appeared speculating about discussions between Con Edison and
Northeast. All subsequent analysis is based on stock trading activity on or
prior to October 6, 1999.

    COMPARABLE PUBLIC COMPANY ANALYSIS

    As part of its analysis, Morgan Stanley compared financial information of
Northeast with that of a group of publicly-traded regulated electric companies.
The comparable companies selected for Northeast were as follows:

</TABLE>

    No company utilized in the comparable public company analysis as a
comparison is identical to Northeast or Con Edison. In evaluating the companies,
Morgan Stanley made judgments and assumptions with regard to industry
performance, general business, economic, market and financial conditions and
other matters, many of which are beyond the control of Northeast and Con Edison,
such as the impact of competition on the businesses of Northeast and Con Edison
and the industry generally, industry growth and the absence of any material
adverse change in the financial condition and prospects of Northeast, Con Edison
or the industry or in the financial markets in general. Mathematical analysis,
such as determining an average or a median, is not in itself a meaningful method
of using comparable public company data.

    Based on this analysis, Morgan Stanley calculated per share trading values
for Northeast common stock ranging from $17.00 to $20.00. This range was also
multiplied by a 25% to 40% premium, including the value of acquiring control of
Northeast, to determine a transaction valuation range. This

                                       49
<PAGE>
control premium range was based on an analysis of control premiums in twelve
announced or completed transactions in the regulated electric utility industry
comparable in certain respects to the merger. See "--Analysis of Selected
Precedent Transactions." Based on this premium range, Morgan Stanley calculated
per share equity transaction values for Northeast ranging from $21.25-$28.00.
Morgan Stanley noted that the unaffected closing per share price of Northeast
common shares on October 6, 1999 was $18.44. Applying a 25% to 40% control
premium range to the unaffected price results in per share equity transaction
values for Northeast ranging from $23.05-$25.81. Similarly, Morgan Stanley
calculated per share trading values for Con Edison common stock ranging from
$41.00 to $47.00.

    DISCOUNTED CASH FLOW ANALYSIS

    Morgan Stanley performed a discounted cash flow analysis of Northeast and
Con Edison. Morgan Stanley's discounted cash flow analysis was based on
financial projections provided by the management of Northeast and Con Edison for
the period 1999 through 2005. Unlevered free cash flow was calculated as net
income available to common shareholders plus the aggregate of preferred stock
dividends, depreciation and amortization, deferred taxes, and other noncash
expenses and after-tax net interest expense less the sum of capital expenditures
and investment in noncash working capital. Morgan Stanley calculated the value
of Northeast and Con Edison as of the end of the period for which projections
were provided by the management of Northeast and Con Edison, also referred to as
the terminal value, by applying a range of EBITDA multiples to the forecasted
EBITDA as of the last year for which projections were provided by the management
of Northeast and Con Edison, also referred to as the exit EBITDA, and the
cash-flow streams and terminal values were then discounted to the present using
a range of discount rates representing an estimated range of the weighted
average cost of capital for each company. The range of discount rates utilized
for the valuation was 6.50%-7.50%. Morgan Stanley determined this range of
discount rates for Northeast and Con Edison by analyzing the weighted average
cost of capital for the Northeast Comparable Companies and the Con Edison
Comparable Companies, respectively. The range of exit EBITDA multiples applied
for this analysis was 6.5x to 7.5x, which is based upon trading multiples of the
Northeast Comparable Companies and the Con Edison Comparable Companies.

    Based on these analyses, Morgan Stanley calculated per share trading values
for Northeast ranging from $18.25 to $23.50 and per share trading values for Con
Edison ranging from $38.00 to $45.00.

    Morgan Stanley performed a discounted cash flow analysis of Northeast
including the value of potential synergy benefits which may result from the
merger. Morgan Stanley's discounted cash flow analysis was based on assumptions
regarding the amount of synergies associated with the regulated and unregulated
operations of Northeast as well as the degree of sharing of regulated synergy
benefits between customers and shareholders.

    Based on these analyses, Morgan Stanley calculated per share transaction
values for Northeast ranging from $20.75 to $26.00.

    ANALYSIS OF SELECTED PRECEDENT TRANSACTIONS

    Using publicly available information, Morgan Stanley considered 12 announced
or completed transactions in the regulated electric utility industry comparable
in certain respects to the merger. These transactions included:

    - Carolina Power & Light Company's acquisition of Florida Progress
      Corporation

    - Energy East Corporation's acquisition of CMP Group, Inc.

    - The National Grid Group plc's acquisition of New England Electric System

    - ScottishPower plc's acquisition of PacifiCorp

    - The AES Corporation's acquisition of CILCORP Inc.

                                       50

    Morgan Stanley compared publicly available financial and market statistics
of the Precedent Transactions to the merger. The table below presents, as of
October 12, 1999, the representative range for each of the ratios of price paid
in the Precedent Transactions to the estimated earnings for the first and second
fiscal years after the announcement of the transactions, the price paid in the
Precedent Transactions to latest reported book value, the price paid in the
Precedent Transactions to LTM operating cash flow, and the aggregate value paid
in the Precedent Transactions to LTM EBITDA.

    Based on an analysis of the corresponding earnings estimates, book value,
LTM operating cash flow and EBITDA for Northeast, Morgan Stanley calculated per
share transaction values for Northeast ranging from $23.00 to $28.00.

    No transaction utilized as a comparison in the analysis of selected
precedent transactions is identical to the merger, and, accordingly, an analysis
of the results of the foregoing necessarily involves complex considerations and
judgments concerning differences in financial and operating characteristics of
Northeast and other factors that would affect the acquisition value of the
companies to which it is being compared. In evaluating the precedent
transactions, Morgan Stanley made judgments and assumptions with regard to
industry performance, general business, economic, market and financial
conditions and other matters, many of which are beyond the control of Northeast,
such as the impact of competition on Northeast and the industry generally,
industry growth and the absence of any adverse material change in the financial
conditions and prospects of Northeast or the industry or in the financial
markets in general. Mathematical analysis, such as determining the mean or
median, is not, in itself, a meaningful method of using precedent transactions
data.

    SUM OF PARTS ANALYSIS

    Given the increasingly complex nature and multitude of businesses in which
Northeast participates, Morgan Stanley performed a variety of analyses to
estimate the value of the individual businesses of Northeast, including the
regulated utility subsidiaries, Northeast's energy marketing business,
Northeast's unregulated generation business, Northeast's energy services
businesses and Northeast's investment in the telecommunications business. Morgan
Stanley conducted a valuation of Northeast's regulated utility subsidiaries, in
a manner consistent with Morgan Stanley's valuation of Northeast as a whole,
based upon, among other things, (i) a comparison of publicly available financial
and market statistics of the Precedent Transactions to the performance of
Northeast's regulated utility subsidiaries, (ii) a comparison of financial
information of Northeast's regulated utility subsidiaries with that of the
Northeast Comparable Companies, multiplied by a 25% to 40% premium to include
the value of acquiring control of Northeast's regulated utility subsidiaries and
(iii) a discounted cash flow analysis of Northeast's regulated utility
businesses provided by the management of Northeast for the period 1999 through
2005. Based on these analyses, Morgan Stanley calculated per share trading
values for

                                       51
<PAGE>
Northeast's regulated utility subsidiaries ranging from $12.00 to $15.00 and per
share transaction values for Northeast's regulated utility subsidiaries ranging
from $16.00 to $19.00.

    Morgan Stanley also performed a variety of analyses to estimate the value of
the remainder of the individual businesses of Northeast. Morgan Stanley included
the market value of the shares of NorthEast Optic Network, Inc. held by
Northeast, valued at a then current trading value of $1.37 per Northeast share.
Morgan Stanley also included the equity value paid by Northeast Generation
Company, an unregulated affiliate of Northeast formed to own and manage
generation facilities, to the Connecticut Light & Power Company and Western
Massachusetts Electric Company for certain hydroelectric generation facilities,
including the Northfield Mountain hydroelectric generation facility, totaling
approximately $3.00 per Northeast share. Morgan Stanley calculated per share
trading values for Northeast's Select Energy business ranging from $.75 to $1.25
and per share transaction values ranging from $1.50 to $2.25. Morgan Stanley
also calculated per share trading values for Northeast's HEC Energy Company and
Northeast Generation Services businesses totaling from $.30 to $.40 and per
share transaction values totaling from $.50 to $.60. Based on these analyses,
Morgan Stanley calculated per share trading values for the remainder of the
individual businesses of Northeast ranging from approximately $5.50 to $6.00 and
per share transaction values ranging from approximately $6.25 to $7.25. Morgan
Stanley also included the value of excess cash projected to be accumulated by
Northeast before the close of the merger between Northeast and Con Edison,
totaling approximately $2.50 per Northeast share.

    Based on these analyses, Morgan Stanley calculated per share trading values
for Northeast ranging from approximately $20.00 to $23.50 and per share
transaction values for Northeast ranging from approximately $24.75 to $28.75.

    PRO FORMA ANALYSIS OF THE MERGER

    Morgan Stanley reviewed the pro forma impact of the merger on Con Edison's
earnings per share ("EPS") for the fiscal years ended 2001 through 2003. The
analysis was performed assuming completion of the merger at the beginning of
this period, utilizing publicly available consensus earnings estimates for the
fiscal years ended 2001 through 2003 for Northeast and Con Edison. The analysis
included assumptions regarding the effects of potential retained synergies.
Based on such analysis, on an EPS basis the merger would be dilutive by 1.6% to
Con Edison in 2001, accretive by 0.4% in 2002 and accretive by 1.7% in 2003.

    In connection with its written opinion dated as of the date of this joint
proxy statement/prospectus, Morgan Stanley reviewed the analyses used to render
its October 12, 1999 opinion by performing procedures to update such analyses
and by reviewing the assumptions upon which such analyses were based and the
factors considered in connection therewith.

    In connection with the review of the merger by Northeast's Board of
Trustees, Morgan Stanley performed a variety of financial and comparative
analyses and considered a number of factors, including Northeast's planned
acquisition of Yankee and the planned divestiture of Northeast's nuclear assets,
for purposes of delivering its opinions. The preparation of a fairness opinion
is a complex process and is not necessarily susceptible to partial analysis or
summary description. In arriving at its opinions, Morgan Stanley considered the
results of all of its analyses as a whole and did not attribute any particular
weight to any analysis or factor considered by it. Furthermore, Morgan Stanley
believes that selecting any portion of its analyses, without considering all
analyses would create an incomplete view of the process underlying its opinions.
In addition, Morgan Stanley may have given various analyses and factors more or
less weight than other analyses and factors, and may have deemed various
assumptions more or less probable than other assumptions, so that the ranges of
valuations resulting from any particular analysis described above should not be
taken to be Morgan Stanley's view of the actual value of Northeast or Con
Edison.

                                       52
<PAGE>
    In performing its analyses, Morgan Stanley made numerous assumptions with
respect to industry performance, general business and economic conditions and
other matters, many of which are beyond the control of Northeast and Con Edison.
Any estimates contained in Morgan Stanley's analysis are not necessarily
indicative of future results or actual values, which may be significantly more
or less favorable than those suggested by such estimates. The analyses performed
were performed solely as part of Morgan Stanley's analysis of the fairness from
a financial point of view of the consideration to be received by the holders of
Northeast common shares pursuant to the merger agreement and were conducted in
connection with the delivery of the Morgan Stanley opinions to Northeast's Board
of Trustees. The analyses do not purport to be appraisals or to reflect the
prices at which Northeast common stock might actually trade. The consideration
pursuant to the merger agreement and other terms of the merger agreement were
determined through arm's length negotiations between Northeast and Con Edison
and were approved by Northeast's Board of Trustees. Morgan Stanley provided
advice to Northeast during such negotiations; however, Morgan Stanley did not
recommend any specific consideration to Northeast or that any specific
consideration constituted the only appropriate consideration for the merger. In
arriving at its opinions, Morgan Stanley was not authorized to solicit, and did
not solicit, interest from any party with respect to an acquisition, business
combination or other extraordinary transaction involving Northeast. Morgan
Stanley's October 12, 1999 opinion was one of many factors taken into
consideration by Northeast's Board of Trustees in making its decision to approve
the merger agreement and the transactions contemplated thereby. Consequently,
the Morgan Stanley analyses as described above should not be viewed as
determinative of the opinion of Northeast's Board of Trustees with respect to
the value of Northeast or whether the Northeast Board of Trustees would have
been willing to agree to a different consideration.

    Northeast's Board of Trustees retained Morgan Stanley based upon Morgan
Stanley's qualifications, experience and expertise. Morgan Stanley is an
internationally recognized investment banking and advisory firm. Morgan Stanley,
as part of its investment banking and financial advisory business, is
continuously involved in the valuation of business and securities in connection
with mergers and acquisitions, negotiated underwritings, competitive biddings,
secondary distributions of listed and unlisted securities, private placements
and valuations for corporate and other purposes. In the ordinary course of
Morgan Stanley's trading and brokerage activities, Morgan Stanley or its
affiliates may at any time hold long or short positions or may trade or
otherwise effect transactions, for its own account or for the account of
customers, in the equity or debt securities or senior loans of Northeast or Con
Edison.

    Morgan Stanley has been retained by Northeast to act as financial advisor to
Northeast with respect to the merger. Pursuant to the letter agreements dated as
of September 15, 1998 and September 14, 1999 between Northeast and Morgan
Stanley, Morgan Stanley is entitled to (i) an advisory fee of approximately
$200,000 to $350,000 which is payable in the event the transaction is not
consummated and (ii) a transaction fee of approximately $9,000,000, which is
payable as follows: one-third upon announcement of the transaction, one-third
upon approval of the transaction by Northeast's shareholders and one-third upon
closing of the transaction. Any amounts paid or payable to Morgan Stanley as
advisory or announcement fees will be credited against the transaction fee.
Northeast has also agreed to reimburse Morgan Stanley for expenses incurred by
Morgan Stanley in performing its services. In addition, Northeast has agreed to
indemnify Morgan Stanley and its affiliates, their respective directors,
officers, agents and each person, if any, controlling Morgan Stanley or any of
its affiliates against certain liabilities and expenses, including certain
liabilities under the federal securities laws, related to or arising out of
Morgan Stanley's engagement and any related transactions. In the past, Morgan
Stanley & Co. Incorporated and its affiliates have provided financial advisory
and financing services for Northeast and for Con Edison and have received fees
for the rendering of these services.

    Morgan Stanley has consented to the inclusion of its opinion dated as of the
date of this joint proxy statement/prospectus and to the inclusion of this
summary of its opinions and its related analyses

                                       53

in this document. In giving this consent, Morgan Stanley did not concede that it
comes within the category of persons whose consent is required under Section 7
of the Securities Act or the rules and regulations of the Securities and
Exchange Commission, nor did it concede that it is an expert with respect to any
part of the registration statement of which this document is a part within the
meaning of the term "experts" as used in the Securities Act or the rules and
regulations of the Securities and Exchange Commission.

    SG BARR DEVLIN

    On July 1, 1998, Northeast engaged SG Barr Devlin to act as Northeast's
financial and strategic advisor in developing and implementing future strategic
and financial courses of action, including a potential business combination. SG
Barr Devlin has delivered written opinions to the Northeast Board of Trustees,
dated October 12, 1999 and the date of this joint proxy statement/prospectus,
which state that, as of such dates and based upon the matters set forth in the
opinions, the merger consideration is fair, from a financial point of view, to
the holders of Northeast common shares.

    A copy of the opinion of SG Barr Devlin, dated the date of this joint proxy
statement/prospectus, is attached as Annex D to this document and incorporated
herein by reference. The October 12, 1999 opinion is substantially identical to
the opinion dated the date of this joint proxy statement/prospectus. In
connection with its opinion dated the date hereof, SG Barr Devlin performed
procedures deemed appropriate by it to update the analysis performed for its
October 12, 1999 opinion and reviewed with the management of Northeast and Con
Edison the assumptions underlying such analysis. These procedures included
taking into consideration current market valuations for the common stock of Con
Edison, Northeast, Northeast Optic Networks, Inc. and the comparable companies
referred to in the discussion below. The results of these analyses provided the
basis upon which SG Barr Devlin confirmed, as of the date hereof, the conclusion
originally set forth in its October 12, 1999 opinion that the merger
consideration is fair, from a financial point of view, to holders of Northeast
common shares. Holders of Northeast common shares should read the attached
opinion carefully and in its entirety.

    In connection with rendering its opinion dated the date of this joint proxy
statement/prospectus, SG Barr Devlin reviewed and relied upon:

    - the annual reports, Forms 10-K and selected other public filings of
      Northeast for the three years ended December 31, 1998 and the Forms 10-Q
      and related unaudited financial information for the quarterly periods
      ended March 31, 1999, June 30, 1999 and September 30, 1999;

    - the annual reports, Forms 10-K, and selected other public filings of Con
      Edison for the three years ended December 31, 1998 and the Form 10-Q and
      related unaudited financial information for the quarterly periods ended
      March 31, 1999, June 30, 1999 and September 30, 1999;

    - internal financial information, including forecasts and related schedules
      provided by Northeast and Con Edison;

    - the merger agreement;

    - this joint proxy statement/prospectus; and

    - other materials deemed by SG Barr Devlin to be necessary or appropriate.

    SG Barr Devlin also:

    - conducted discussions with members of senior management of Northeast and
      Con Edison about their businesses, regulatory environments, prospects and
      strategic objectives;

    - reviewed the historical market prices and trading activity for Northeast
      common shares and Con Edison common shares;

    - compared financial and operational information for Northeast and Con
      Edison with similar information for certain other companies;

                                       54
<PAGE>
    - compared the proposed financial terms of the merger with similar
      information from similar utility industry business combinations and
      adjusted those terms to reflect changes in the utility industry market
      environment;

    - analyzed the valuation of Northeast common shares and Con Edison common
      shares using a variety of valuation methodologies; and

    - performed other studies and analyses as it deemed appropriate.

    SG Barr Devlin relied upon the accuracy and completeness of all financial
and other information provided to it by Northeast and Con Edison, and upon the
assurances of management of Northeast and Con Edison that they were not aware of
any facts that would make such information inaccurate or misleading. SG Barr
Devlin also relied upon the assurances of management of Northeast and Con Edison
that all financial projections were reasonably prepared and reflected the best
currently available estimates and judgments regarding future financial
performance and the projected outcomes of legal, regulatory and other
contingencies. These projections and estimates do not necessarily indicate
actual values or predict future results or values, which may be significantly
more or less favorable than projected or estimated. SG Barr Devlin was not
provided with and did not undertake an independent evaluation or appraisal of
the assets or liabilities of Northeast or Con Edison, nor did SG Barr Devlin
make any physical inspection of the properties or assets of Northeast or Con
Edison.

    SG Barr Devlin assumed that the merger would be a reorganization within the
meaning of Section 351 of the Internal Revenue Code of 1986, as amended, and
that holders of Northeast common Shares who exchange their shares for Con Edison
common shares would recognize no gain or loss for federal income tax purposes as
a result of the consummation of the merger. SG Barr Devlin assumed that the
merger would be accounted for by the purchase method of accounting. SG Barr
Devlin's opinions are necessarily based upon general financial, stock market and
other conditions and circumstances as they existed and could be evaluated, and
the information made available to it as of the dates of the opinions.

    SG Barr Devlin's opinions are directed to the Northeast Board of Trustees
and the fairness, from a financial point of view, of the merger consideration
taken as a whole (and not to the fairness of the cash consideration, the stock
consideration or any combination thereof individually, as to which SG Barr
Devlin is expressing no opinion). They do not address any other aspect of the
merger and do not constitute a recommendation to any holder of Northeast common
shares as to how such holder should act with respect to the merger. The merger
consideration itself was determined by Northeast and Con Edison through
arm's-length negotiations. Northeast did not place any limitations upon SG Barr
Devlin regarding the procedures followed or factors considered by SG Barr Devlin
in rendering its opinions.

    In rendering its fairness opinions dated October 12, 1999 and the date of
this joint proxy statement/prospectus and making its presentations to the
Northeast Board of Trustees, SG Barr Devlin performed a variety of financial and
comparative analyses and considered a variety of factors, including Northeast's
planned acquisition of Yankee and the planned divestiture of Northeast's nuclear
assets. While other material analyses and factors are summarized below, this
summary is not a complete description. Furthermore, SG Barr Devlin did not
attribute any particular weight to any analysis or factor; rather, SG Barr
Devlin made its determination on the basis of qualitative judgments regarding
the significance and relevance of each analysis and factor. Accordingly, SG Barr
Devlin believes that its analyses must be considered as a whole, and that only
considering portions of these analyses and factors could create a misleading or
incomplete view of the evaluation process underlying its opinions. The results
of these analyses, in connection with SG Barr Devlin's opinion dated
October 12, 1999, were discussed with Northeast's Board of Trustees at its
meeting on October 12, 1999.

    STOCK TRADING HISTORY

    SG Barr Devlin reviewed the historical prices and trading activity of
Northeast common shares and Con Edison common shares and compared them to the
Standard and Poor's Utility Index. This index

                                       55
<PAGE>
was selected because it is composed of companies with business characteristics
similar to Northeast and Con Edison. This comparison provided perspective on the
current and historical stock price performance of Northeast and Con Edison
relative to one another and to the selected indices. This analysis was utilized
to provide historical background regarding the manner in which the public
trading market had valued Northeast and Con Edison in absolute terms and
relative to each other.

    The following table presents the change in value from the Standard and
Poor's Utility Index, as compared to the change in the share prices of Northeast
common shares and Con Edison common shares over the period from January 4, 1999
to October 8, 1999, the last full trading day prior to the preparation of SG
Barr Devlin's presentation to Northeast's Board of Trustees:

Northeast and Con Edison with the corresponding financial information and ratios
for a group of publicly traded electric utilities (or their holding companies)
deemed by SG Barr Devlin to be comparable to Northeast and Con Edison. These
comparable companies were selected on the basis of being companies that
possessed general business, operating and financial characteristics
representative of companies in the industry in which Northeast operates. The
following table lists the comparable companies that were used:

    SG Barr Devlin determined ranges of multiples for the comparable companies
based on the following financial ratios for Northeast:

    - common share market value as a multiple of:

       - projected net income for the 12-month period ended December 31, 2000;

       - projected net income for the 12-month period ended December 31, 2001;

    - aggregate market value (defined as the sum of the common share market
      value, plus any preferred shares, debt, capitalized lease obligations and
      minority interests, minus cash and cash equivalents) as a multiple of:

       - projected earnings before interest, taxes, depreciation and
         amortization for the 12-month period ended December 31, 2000.

    Applying such multiples to the corresponding data for Northeast, this
analysis produced a value range of $19.00 to $20.25 per Northeast common share,
including the value of a 29% interest in common stock of publicly traded
Northeast Optic Network, Inc. valued at the then current trading value of $1.37
per Northeast common share. The weighted average value of this range was $19.63.

    SG Barr Devlin determined ranges of multiples for the comparable companies
based on the following financial ratios for Con Edison:

    - common share market value as a multiple of:

       - net income for the 12-month period ended June 30, 1999;

       - projected net income for the 12-month period ended December 31, 1999;

       - projected net income for the 12-month period ended December 31, 2000;

       - book value for the period ended June 30, 1999;

    - aggregate market value (defined as the sum of the common share market
      value, plus any preferred shares, debt, capitalized lease obligations and
      minority interests, minus cash and cash equivalents) as a multiple of:

       - earnings before interest and taxes for the 12-month period ended
         June 30, 1999;

       - earnings before interest, taxes, depreciation and amortization for the
         12-month period ended June 30, 1999.

</TABLE>

    Applying such multiples to the corresponding data for Con Edison, this
analysis produced a value range of $38.00 to $44.50 per Con Edison common share
with a weighted average value of $41.25.

    Because of the inherent differences between the operations of Northeast and
Con Edison and the comparable companies, SG Barr Devlin believes that a purely
quantitative analysis is not particularly meaningful in the context of the
merger. In this instance, SG Barr Devlin believes that an appropriate use of the
comparable company analysis also involves qualitative judgments concerning
differences between the characteristics of the comparable companies and
Northeast and Con Edison. Moreover, SG Barr Devlin believes that the comparable
company analysis by itself does not reflect the potential incremental value to
Con Edison of a controlling interest in Northeast.

    DISCOUNTED CASH FLOW ANALYSIS

    SG Barr Devlin prepared and reviewed the results of unleveraged discounted
cash flow analyses for both Northeast and Con Edison, assuming that Northeast
and Con Edison performed according to the operating and financial projections
provided by their management for the period 1999 through 2005 for Northeast and
the period 1999 through 2003 for Con Edison, as revised by SG Barr Devlin to
reflect adjustments it deemed appropriate, primarily to the projected earnings
growth for each company's non-regulated businesses. Such adjustments reflect the
historical performance of the companies' non-regulated businesses as well as the
level of risk for such businesses. The purpose of the discounted cash flow
analysis was to estimate a range of values for the stock of Northeast and Con
Edison.

    For Northeast, the value calculated represents a composite value of
Northeast's regulated and non-regulated businesses. Values for Northeast's
non-regulated businesses reflect the blended values of a discounted cash flow
analysis with the sum of the value of the then current equity trading value of a
29% interest in the common stock of publicly traded Northeast Optical
Network, Inc., equity purchase price for assets under purchase agreement, and
comparable multiples applied to corresponding Northeast 2001 earnings statistics
for the remainder of non-regulated operations.

    The projected cash flows for Northeast's regulated and non-regulated
businesses from January 1, 2001 through December 31, 2005, together with the
estimated value of Northeast's regulated and non-regulated businesses at the end
of 2005, were discounted to January 1, 2001 using discount rates that ranged
from 6.25% to 7.25% for Northeast's regulated businesses and 10%-12% for
Northeast's non-regulated businesses. These discount rates are based on SG Barr
Devlin's estimates of the weighted average cost of capital for Northeast's
respective businesses. Equity values at January 1, 2001 were discounted to the
present using a discount rate of 9% for Northeast's regulated businesses and
16.5% for Northeast's non-regulated businesses, which represent SG Barr Devlin's
estimate of the cost of equity for Northeast's respective businesses.

<PAGE>
    SG Barr Devlin estimated values at the end of 2005 for Northeast's regulated
and non-regulated businesses by applying the following multiples set forth in
the table below that were derived from those of certain comparable public
companies. These comparable public companies were selected on the basis of being
companies that possessed general business, operating and financial
characteristics representative of companies in the industry in which Northeast
operates. These comparable public companies are the same companies listed under
the subheading "Publicly Traded Comparable Company Analysis."

<TABLE>
<S>                                                           <C>
Earnings before interest and taxes..........................         9.0x--10.0x
Earnings before interest, taxes, depreciation and
  amortization..............................................          6.5x--7.5x
Net income..................................................        12.5x--13.5x
</TABLE>

    This analysis produced a value range for Northeast's regulated businesses of
$13.75 to $17.00 per Northeast common share with a weighted average of $15.38
and a value range for Northeast's non-regulated businesses of $5.25 to $6.25 per
Northeast common share with a weighted average of $5.75. Combining the per share
value of Northeast's regulated and nonregulated businesses produces a combined
value range of $19.00 to $23.25, with a weighted average of $21.13.

    To calculate an estimated range of values for the shares of Con Edison, Con
Edison's projected cash flows during each year of the projections, together with
the estimated value of Con Edison at the end of 2003, were discounted to the
present using discount rates that ranged from 6.50% to 7.50%, which represent SG
Barr Devlin's estimate of the weighted average cost of capital for Con Edison.
SG Barr Devlin estimated values at the end of 2003 for Con Edison by applying
the following multiples that were derived from those of certain comparable
public companies:

<TABLE>
<S>                                                           <C>
Earnings before interest and taxes..........................         9.0x--10.5x
Earnings before interest, taxes, depreciation and
  amortization..............................................          6.5x--7.5x
Book value..................................................        1.45x--1.80x
Net income..................................................        12.5x--14.0x
</TABLE>

    This analysis produced a value range for Con Edison of $38.25 to $47.00 per
Con Edison common share with a weighted average of $42.63.

    COMPARABLE TRANSACTION ANALYSIS

    SG Barr Devlin compared selected financial information and ratios for the
regulated businesses of Northeast with the corresponding financial information
and ratios for certain comparable transactions involving acquisitions of
electric utilities (or their holding companies). These comparable transactions
were selected because they were strategic combinations of companies that
possessed general business, operating and financial characteristics
representative of companies in the industry in which Northeast operates. The
comparable transactions included:

    - Carolina Power & Light Company/Florida Progress Corporation;

    - Energy East Corporation/CMP Group, Inc.;

    - Private Investor Group/TNP Enterprises, Inc.

    - Utilicorp United Inc./Empire District Electric Company;

    - Utilicorp United Inc./St. Joseph Light & Power Company;

    - New England Electric System/Eastern Utilities Associates;

    - The National Grid Group plc/New England Electric System;

    - ScottishPower plc/PacifiCorp;

                                       59
<PAGE>
    - The AES Corporation/CILCORP Inc.;

    - CalEnergy Company, Inc./MidAmerican Energy Holdings Company; and

    - Con Edison/Orange & Rockland Utilities, Inc.

    SG Barr Devlin determined implied ranges of multiples from the comparable
transactions based on the following financial ratios:

    - implied consideration to be received by the smaller company's shareholders
      as a multiple of its projected net income for the next fiscal year; and

    - implied percentage premium to the smaller company's shareholders by
      dividing the offer price over the one-day and one-month unaffected stock
      market prices for their shares.

    The following table sets forth the results of these calculations:

</TABLE>

    These multiples were applied to the corresponding data for Northeast's
regulated businesses excluding the pending acquisition of Yankee. Taken together
with the equity purchase price of pending acquisitions and the estimated ranges
of values for the remaining businesses of Northeast produced by a variety of
analytic methods, this analysis produced a value range of $23.50 to $27.00 per
Northeast common share with a weighted average of $25.25.

    Because the reasons for and circumstances surrounding each of the comparable
transactions were diverse and because of the inherent differences between the
operations of Northeast and the companies in the selected transactions, SG Barr
Devlin believes that a purely quantitative analysis is not particularly
meaningful in the context of the merger. In this instance, SG Barr Devlin
believes that an appropriate use of the comparable transaction analysis also
involves qualitative judgments concerning differences between the
characteristics of these transactions and the merger that would affect the value
of Northeast.

    PRO FORMA MERGER ANALYSIS

    SG Barr Devlin analyzed certain pro forma effects of the merger to holders
of Northeast common shares for the period 2001 through 2003. This analysis was
based upon publicly available consensus earnings estimates for Northeast and Con
Edison as of October 8, 1999, and giving effect to possible benefits which might
be realized following the merger. For holders of Northeast common shares
receiving the stock consideration, the analysis showed substantial improvement
in earnings per share, with an even greater percentage improvement in dividends
per share. See "The Merger--Dividends."

    SG Barr Devlin was selected as Northeast's financial advisor because SG Barr
Devlin and principals of SG Barr Devlin have significant experience in the
investment banking and electric and gas utility industries. SG Barr Devlin is a
division of SG Cowen Securities Corporation specializing in strategic and merger
advisory services to the electric and gas utility industries, the energy
industry and selected other industries. In this capacity, SG Barr Devlin and
principals of SG Barr Devlin have been involved as advisors in numerous
transactions and advisory assignments in the electric, gas and energy industries
and are constantly engaged in the valuation of businesses and securities in
these industries.

    Pursuant to the engagement letter dated as of July 1, 1998, Northeast has
agreed to pay SG Barr Devlin a transaction fee for services related to the
merger. This transaction fee is based on the aggregate value to be received by
Northeast shareholders at the time of the closing of the merger. The transaction
fee, which is currently estimated to be $9,000,000, is payable in three
installments: one-third upon execution of the merger agreement, one-third upon
approval of the merger agreement by Northeast shareholders and one-third at the
time of closing.

    Northeast has agreed to reimburse SG Barr Devlin for its out-of-pocket
expenses, including fees and expenses of legal counsel and other advisors
engaged with the consent of Northeast, and to indemnify SG Barr Devlin against
some liabilities, including liabilities under the federal securities laws,
relating to or arising out of its engagement.

    SG Barr Devlin has consented to the inclusion of its opinion dated the date
of this joint proxy statement/prospectus and to the inclusion of this summary of
its opinions and their related analyses in this document. In giving this
consent, SG Barr Devlin did not concede that it comes within the category of
persons whose consent is required under Section 7 of the Securities Act or the
rules and regulations of the Securities and Exchange Commission, nor did it
concede that it is an expert with respect to any part of the registration
statement of which this document is a part within the meaning of the term
"experts" as used in the Securities Act or the rules and regulations of the
Securities and Exchange Commission.

INTERESTS OF CON EDISON'S DIRECTORS AND MANAGEMENT IN THE MERGER

    CONTINUING BOARD AND MANAGEMENT POSITIONS

    As provided in the merger agreement, at the completion of the merger, New
Con Edison's Board of Directors will consist of members designated by Con Edison
plus four members recommended by Northeast and reasonably acceptable to Con
Edison. The merger agreement also provides that the officers of Con Edison will
be the officers of New Con Edison, except with respect to the President of New
Con Edison. Eugene R. McGrath, currently the Chairman, President and Chief
Executive Officer of Con Edison, will continue as Chairman and Chief Executive
Officer of New Con Edison.

INTERESTS OF NORTHEAST'S TRUSTEES AND MANAGEMENT IN THE MERGER

    CONTINUING BOARD AND MANAGEMENT POSITIONS

    As provided in the merger agreement, at the completion of the merger, New
Con Edison's Board of Directors will include four members recommended by
Northeast and reasonably acceptable to Con Edison. The merger agreement also
provides that Michael G. Morris will be President of New Con Edison at the
completion of the merger.

    OUTSTANDING STOCK-BASED GRANTS UNDER NORTHEAST INCENTIVE PLAN

    Northeast's executive officers participate in an incentive compensation plan
that contains change of control provisions. The consummation of the merger will
constitute a "change of control" for purposes of the plan. Upon a change of
control,

    - all outstanding options and stock appreciation rights become fully
      exercisable, and

    - the restrictions and conditions on all restricted shares lapse and cash
      payments in respect of outstanding performance units are triggered.

All of Northeast's executive officers' currently outstanding stock appreciation
rights are currently fully exercisable and the performance periods for all
currently outstanding performance units ended in accordance with their terms in
December 1999, with payment occurring in the first half of 2000 and,
accordingly, should not be affected by the merger. The merger agreement
contemplates that all options and stock appreciation rights outstanding at the
effective time of the merger will be assumed or replaced by New Con Edison with
comparable options and rights.

    EMPLOYMENT AGREEMENTS AND SEVERANCE ARRANGEMENTS

    Each of Northeast's executive officers is a party to an employment agreement
or a participant in a special severance program. Upon any "termination upon a
change of control," as defined, of employment of any of these officers during
the period beginning at Northeast shareholder approval of the merger and ending
two years following consummation of the merger or at the date, if any, on which
Northeast's Board of Trustees abandons the merger, if the officer signs a
release of all claims against Northeast the officer will be entitled to payments
including a multiple, not to exceed three, of annual base salary, together with
annual incentive payments, specified employee welfare and pension benefits,
vesting of stock appreciation rights, options and restricted shares and cash
payments in respect of outstanding performance units. The term "termination upon
a change of control" includes termination by Northeast or, following the merger,
by New Con Edison, and, in circumstances specified in the employment agreement
or special severance program, termination by the officer due to a failure of
Northeast or New Con Edison to comply with the terms of the employment agreement
or special severance program including, among other things, a significant
reduction by Northeast or New Con Edison of the officer's authority, duties or
responsibilities. Four Northeast officers' agreements (Messrs. Morris, Kenyon
and Forsgren and Mrs. Grise) provide that a change in the scope of their
authority, such that their responsibilities relate primarily to a company whose
common equity is not publicly held, would be considered a significant reduction
by Northeast or New Con Edison of such officer's authority, duties or
responsibilities. In addition, some of the officers' employment agreements
provide an additional payment to make the officers whole for any excess
parachute payment excise taxes they might incur.

    The following is an estimate of:

    - amounts that would be paid and the value of other supplemental retirement
      and other benefits that would be provided if the chief executive officer
      and the next four highest paid executive officers of Northeast were to be
      "terminated upon a change of control," assuming a termination date of July
      1, 2000,

    In addition, upon a qualifying termination of employment, compensation
previously deferred under Northeast's executive deferred compensation plan will
be paid to the participants in such plan.

    Officers who do not sign release agreements would not be entitled to the
severance benefits provided under their respective employment agreements and
special severance program, but may be entitled to the benefits provided under
Northeast's regular severance program. Such program provides for two weeks' pay
per year of service, to a maximum of one year's pay, plus payment of six months'
medical insurance premiums and three months of outplacement assistance. No
estimate of amounts reasonably expected to be paid to participants under the
severance programs can be made because the numbers of terminations that would be
covered by the program cannot be determined at this time.

INDEMNIFICATION AND INSURANCE

    Under the merger agreement, New Con Edison has agreed to assume the same
obligations with respect to indemnification of current and former directors,
trustees and officers of Con Edison or Northeast as were contained in the
governing documents of Con Edison or Northeast at the date of signing the merger
agreement. In addition, after the completion of the merger, the directors,
trustees and officers of Con Edison or Northeast who become directors or
officers of New Con Edison will be entitled to the indemnity rights and
protections afforded to directors and officers of New Con Edison. Finally, New
Con Edison will maintain the directors', trustees' and officers' liability
insurance policies currently maintained by Con Edison or Northeast, or
substantially comparable policies as in effect upon the completion of the
merger, for a period of six years following the completion of the merger.

                                       63
<PAGE>
LISTING OF NEW CON EDISON CAPITAL STOCK

    It is a condition to the completion of the merger that New Con Edison common
stock issuable to Con Edison and Northeast shareholders pursuant to the merger
agreement be approved for listing on the New York Stock Exchange, subject to
official notice of issuance.

DIVIDENDS

    Con Edison and Northeast do not anticipate making any changes to their
dividend policies prior to the consummation of the merger; however, the Con
Edison and Northeast Boards will continue to evaluate their respective dividend
policies in light of business, financial and regulatory considerations. The most
recent quarterly dividend declared by Con Edison was $.545 per share payable on
March 15, 2000. Con Edison's current dividend is $2.18 per common share on an
annual basis. The most recent quarterly dividend declared by Northeast was $.100
per share payable on March 31, 2000.

    We expect that, after the merger, New Con Edison will continue the dividend
of Con Edison at the time of the merger. As a result, based upon Con Edison's
current dividend, New Con Edison's estimated aggregate annual dividend payments
would be approximately $143.7 million greater than those of Con Edison. Although
this increase in aggregate dividend payments will impact New Con Edison's
liquidity, it is not expected to have an adverse effect on New Con Edison's
business. The payment of dividends by New Con Edison, however, will be subject
to approval and declaration by the New Con Edison Board of Directors, and will
depend on a variety of factors, including business, financial and regulatory
considerations. It is expected that New Con Edison will pay future dividends out
of dividends from subsidiaries.

MERGER CONSIDERATION FINANCING

    Con Edison has not entered into any agreements or made any arrangements with
respect to financing the cash portion of the merger consideration. Con Edison
expects to finance the cash portion of the merger consideration with cash on
hand, the incurrence of long-term or short-term indebtedness or a combination of
the foregoing. Con Edison does not expect to experience any difficulty in
obtaining the requisite financing.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

    The following summary discusses the material U.S. federal income tax
consequences of the merger to Con Edison and Northeast shareholders. This
discussion is based upon the United States Internal Revenue Code of 1986,
Treasury regulations, administrative rulings and judicial decisions currently in
effect. All of the foregoing are subject to change, possibly with retroactive
effect, and any such change could affect the continuing validity of the
following summary.

    The discussion is limited in the following ways. The discussion assumes that
shareholders hold their Con Edison common shares, Northeast common shares and
New Con Edison common stock as a capital asset within the meaning of
Section 1221 of the Internal Revenue Code, because that will be true of most
shareholders who are not broker-dealers. The discussion does not address all
aspects of U.S. federal income taxation that may be relevant to a particular
shareholder in light of that shareholder's personal investment circumstances.
The discussion does not apply to shareholders subject to special treatment under
the U.S. federal income tax laws, such as insurance companies, tax-exempt
organizations, financial institutions, broker-dealers, persons that hold Con
Edison common shares or Northeast common shares as part of a straddle or
conversion transaction or persons who acquired Con Edison common shares or
Northeast common shares through the exercise of employee stock options or
otherwise as compensation. Furthermore, the discussion does not consider the
potential effects of any state, local or foreign tax laws.

    None of New Con Edison, Con Edison or Northeast has requested a ruling from
the United States Internal Revenue Service with respect to any of the U.S.
federal income tax consequences of the merger. As a result, there can be no
assurance that the Internal Revenue Service will agree with any of the
conclusions described below.

                                       64
<PAGE>
    HOLDERS OF CON EDISON COMMON SHARES AND NORTHEAST COMMON SHARES SHOULD
CONSULT THEIR OWN TAX ADVISORS REGARDING THE SPECIFIC TAX CONSEQUENCES TO THEM
OF THE MERGER, INCLUDING THE APPLICABILITY AND EFFECT OF FEDERAL, STATE, LOCAL
AND FOREIGN INCOME AND OTHER TAX LAWS IN THEIR PARTICULAR CIRCUMSTANCES.

    For purposes of this discussion, "U.S. Holder" means:

    (1) a citizen or resident of the United States,

    (2) a corporation or other entity taxable as a corporation created or
       organized under the laws of the United States or any of its political
       subdivisions, or

    (3) an estate or trust that is subject to U.S. federal income tax on its
       income regardless of its source.

    Cravath, Swaine & Moore, counsel to Con Edison, has delivered its opinion to
Con Edison to the effect that (i) the Con Edison merger will be treated for U.S.
federal income tax purposes as a reorganization within the meaning of
Section 368(a) of the Internal Revenue Code and that Con Edison and New Con
Edison will each be a party to that reorganization within the meaning of
Section 368(b) of the Internal Revenue Code and (ii) the statements made under
the heading "The Merger--Material U.S. Federal Income Tax Consequences of the
Merger," to the extent they constitute statements of law or legal conclusions
and subject to the limitations contained therein, are correct and describe the
material U.S. federal income tax consequences of the merger to Con Edison and
Northeast shareholders. LeBoeuf, Lamb, Greene & MacRae, L.L.P., counsel to
Northeast, has delivered its opinion to Northeast to the effect that (i) the
Northeast merger, taken together with the Con Edison merger, will be treated for
U.S. federal income tax purposes as a transaction described in Section 351 of
the Internal Revenue Code and (ii) the statements made under the heading "The
Merger--Material U.S. Federal Income Tax Consequences of the Merger," to the
extent they constitute statements of law or legal conclusions and subject to the
limitations contained therein, are correct and describe the material U.S.
federal income tax consequences of the merger to Con Edison and Northeast
shareholders. The tax opinions are subject to qualifications and are based on
currently applicable law, factual representations made by Con Edison, Northeast
and New Con Edison in their representation letters, forms of which are attached
as Exhibits E, F and G, respectively, to Annex A, and various assumptions.

    The material factual representations made by Con Edison, Northeast and New
Con Edison in their respective letters concern (i) any planned stock repurchases
or other distributions by any party to the merger, (ii) any planned disposition
of any property of any of the parties to the merger, and (iii) New Con Edison's
intended use of any property received in the merger. The material assumptions
are that (i) the merger will be consummated as contemplated by the registration
statement and in accordance with the provisions set forth in the merger
agreement, (ii) any statements concerning the merger set forth in the merger
agreement or the registration statement are true, correct and complete and
(iii) any factual representations made by Con Edison, Northeast or New Con
Edison concerning the merger are true, correct and complete, and any of those
factual representations that are made "to the best knowledge of" or similarly
qualified are true, correct and complete without such qualification. Moreover,
the tax opinions are in no way binding on the Internal Revenue Service or any
courts. Any change in currently applicable law, which may or may not be
retroactive, or failure of any of such factual representations or assumptions to
be true, correct and complete in all material respects, could affect the
continuing validity of the tax opinions. The tax opinions are exhibits to the
registration statement, on Form S-4, filed with the Securities and Exchange
Commission, which includes this joint proxy statement/prospectus. See "Where You
Can Find More Information" on page 117.

    The statements set forth in the remaining discussion under this heading "The
Merger--Material U.S. Federal Income Tax Consequences of the Merger," to the
extent they constitute statements of law

                                       65
<PAGE>
or legal conclusions and subject to the limitations contained herein and the
limitations described in the above tax opinions, represent the opinions of
Cravath, Swaine & Moore and LeBoeuf, Lamb, Greene & MacRae, L.L.P.

    U.S. HOLDERS OF CON EDISON COMMON SHARES

    No gain or loss will be recognized by U.S. Holders who exchange their Con
Edison common shares solely for New Con Edison common stock. The aggregate
adjusted tax basis of the New Con Edison common stock will be the same as the
aggregate adjusted tax basis of those Con Edison common shares. The holding
period of New Con Edison common stock will include the holding period of those
Con Edison common shares.

    U.S. HOLDERS OF NORTHEAST COMMON SHARES

        U.S. HOLDERS OF NORTHEAST COMMON SHARES WHO RECEIVE SOLELY NEW CON
     EDISON COMMON STOCK

    No gain or loss will be recognized by U.S. Holders of Northeast common
shares who exchange their Northeast common shares, together with the shareholder
rights pursant to the Northeast rights agreement, solely for New Con Edison
common stock except with respect to any cash received instead of a fractional
share. The aggregate adjusted tax basis of the New Con Edison common stock
received by each such U.S. Holder will be the same as the aggregate adjusted tax
basis of those Northeast common shares and the shareholder rights pursant to the
Northeast rights agreement. The holding period of New Con Edison common stock
will include the holding period of those Northeast common shares.

    If the Northeast merger closes prior to December 31, 2000, U.S. Holders may
realize additional income in connection with the receipt of a right to
potentially receive after the Northeast merger closes an additional $1.00 per
Northeast common share converted in the Northeast merger (the "divestiture
right"). See "Possibility of Receiving $1.00 per Northeast Common Share After
the Merger" for a discussion of the tax consequences to U.S. Holders who receive
the divestiture right.

        U.S. HOLDERS OF NORTHEAST COMMON SHARES WHO RECEIVE SOLELY CASH

    A U.S. Holder of Northeast common shares who exchanges those Northeast
common shares, together with the shareholder rights pursant to the Northeast
rights agreement, solely for cash pursuant to the Northeast merger will
generally recognize capital gain or loss in an amount equal to the difference
between the amount of cash received and the U.S. Holder's adjusted tax basis in
the Northeast common shares and the shareholder rights pursant to the Northeast
rights agreement. The capital gain or loss recognized will be long-term capital
gain or loss if the U.S. Holder's holding period for the Northeast common shares
exceeds one year. Some non-corporate U.S. Holders will be eligible for a maximum
U.S. federal income tax rate of 20% on long-term capital gain.

    If the Northeast merger closes prior to December 31, 2000, U.S. Holders may
realize additional income in connection with the receipt of the divestiture
right. See "Possibility of Receiving $1.00 per Northeast Common Share After the
Merger" for a discussion of the tax consequences to U.S. Holders who receive the
divestiture right.

        U.S. HOLDERS OF NORTHEAST COMMON SHARES WHO RECEIVE NEW CON EDISON
    COMMON STOCK AND CASH

    A U.S. Holder of Northeast common shares who exchanges those Northeast
common shares, together with the shareholder rights pursuant to the Northeast
rights agreement, for both cash

                                       66
<PAGE>
consideration and New Con Edison common stock pursuant to the Northeast merger
generally will realize gain or loss in an amount equal to the difference
between:

    (i) the sum of the cash and the fair market value of the New Con Edison
        common stock received, and

    (ii) the U.S. Holder's adjusted tax basis in the Northeast common shares and
         the shareholder rights pursuant to the Northeast rights agreement.

    The U.S. Holder's gain, if any, will be recognized, however, only to the
extent of the amount of cash received. Any loss will not be recognized. Any gain
recognized by the U.S. Holder generally will be treated as capital gain. Some
non-corporate U.S. Holders will be eligible for a maximum U.S. federal income
tax rate of 20% on long-term capital gain.

    A U.S. Holder of Northeast common shares who exchanges those Northeast
common shares, together with the shareholder rights pursuant to the Northeast
rights agreement, for both cash and New Con Edison common stock, will have an
aggregate adjusted tax basis in the New Con Edison common stock received in the
Northeast merger equal to the aggregate adjusted tax basis of the Northeast
common shares and the shareholder rights pursuant to the Northeast rights
agreement, increased by the amount of gain, if any, recognized by such U.S.
Holder and decreased by the amount of cash received. The holding period of the
New Con Edison common stock received will include the holding period of those
Northeast common shares. Adjustments for cash received instead of fractional
shares are described below.

    If the Northeast merger closes prior to December 31, 2000, U.S. Holders may
realize additional income in connection with the receipt of the divestiture
right. See "Possibility of Receiving $1.00 per Northeast Common Share After the
Merger" for a discussion of the tax consequences to U.S. Holders who receive the
divestiture right.

        U.S. HOLDERS OF NORTHEAST COMMON SHARES WHO RECEIVE CASH INSTEAD OF
    FRACTIONAL SHARES

    A U.S. Holder of Northeast common shares who receives cash instead of a
fractional share of New Con Edison common stock should be treated as having
received the fractional share in the Northeast merger and then having exchanged
the fractional share for cash in a redemption by New Con Edison. In that case,
the preceding discussion of gain, loss and tax basis would apply as if the U.S.
Holder had actually received fractional shares of New Con Edison common stock.
In addition, the U.S. Holder would generally recognize capital gain or loss
equal to the difference between the amount of cash received and that U.S.
Holder's adjusted tax basis in the New Con Edison common stock that is allocable
to the fractional share. Some non-corporate U.S. Holders will be eligible for a
maximum U.S. federal income tax rate of 20% on long-term capital gain. It is
possible, however, that the cash received instead of a fractional share of New
Con Edison common stock would instead be treated in the same manner as other
cash received in the Northeast merger. See "U.S. Holders of Northeast Common
Shares Who Receive New Con Edison Common Stock and Cash."

        POSSIBILITY OF RECEIVING $1.00 PER NORTHEAST COMMON SHARE AFTER THE
    MERGER

    If the Northeast merger closes prior to December 31, 2000 and specified
conditions relating to the divestiture of some of Northeast's nuclear assets are
not satisfied on such closing date, each Northeast shareholder will receive the
divestiture right. If the divestiture condition is met on or prior to
December 31, 2000, each holder of a divestiture right will receive a $1.00
payment in respect of that right. The discussion under this heading assumes the
U.S. Holder is an individual or another cash basis taxpayer. The tax
consequences to a U.S. Holder who is not a cash basis taxpayer may differ.

    The receipt by a U.S. Holder in the Northeast merger of the divestiture
right should generally be taxable to the extent of the fair market value of such
right on the date the Northeast merger closes as if such U.S. Holder had
received cash in an amount equal to such fair market value. See "U.S. Holders

                                       67
<PAGE>
of Northeast Common Shares Who Receive Solely Cash" or "U.S. Holders of
Northeast Common Shares Who Receive New Con Edison Common Stock and Cash," as
applicable. The receipt by a U.S. Holder of a $1.00 payment in respect of the
divestiture right should generally be taxable to the extent the $1.00 payment
exceeds the fair market value of the divestiture right on the day the Northeast
merger closes. If no $1.00 payment is received, a U.S. Holder of Northeast
common shares should recognize a loss, in the tax year that includes
December 31, 2000, equal to the income or gain recognized in connection with the
receipt of the divestiture right.

    Because the tax consequences of the receipt of a contingent right to receive
additional cash in connection with a tax free transaction described in
Section 351 of the Internal Revenue Code is uncertain, U.S. Holders of Northeast
common shares are urged to consult their own tax advisors concerning the
specific tax consequences (including the timing, amount and character of any
income or loss recognized) to them of the receipt of the divestiture right.

        BACKUP WITHHOLDING

    Some non-corporate Northeast shareholders may be subject to backup
withholding at a 31% rate on cash payments received in connection with the
Northeast merger (including cash paid instead of fractional shares of New Con
Edison common stock and the $1.00 per Northeast share payments that may be
received after the closing of the merger). Backup withholding will not apply,
however, to a Northeast shareholder who (1) furnishes a correct taxpayer
identification number and certifies as to not being subject to backup
withholding on the substitute Form W-9 or successor form which will be included
in the letter of transmittal to be delivered to Northeast shareholders prior to
the closing of the merger, (2) provides a certification of foreign status on
Form W-8 or successor form or (3) is otherwise exempt from backup withholding.

    If you do not provide a correct taxpayer identification number, you 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 your U.S. federal income tax liability. You should consult with your own
tax advisors as to your qualification for exemption from backup withholding and
the procedure for obtaining the exemption.

    YOU MAY PREVENT BACKUP WITHHOLDING BY COMPLETING A SUBSTITUTE FORM W-9 OR
SUBSTITUTE FORM W-8, AS APPLICABLE, AND SUBMITTING IT TO THE PAYING AGENT FOR
THE MERGER WHEN YOU SUBMIT YOUR NORTHEAST COMMON SHARE CERTIFICATES.

    DISCLOSURE REQUIREMENTS

    The former holders of Con Edison common shares and Northeast common shares
will be required to attach to their income tax returns for the taxable year in
which the closing of the merger occurs, and maintain a permanent record of, a
complete statement of all the facts relating to the exchange of shares in
connection with the merger. The facts to be disclosed by a former holder include
the former holder's basis in the Con Edison common shares or in the Northeast
common shares and the shareholder rights pursuant to the Northeast rights
agreement, as the case may be, transferred to New Con Edison and the number of
shares of New Con Edison common stock received in the merger.

    CONSEQUENCES TO CON EDISON, NEW CON EDISON AND NORTHEAST

    No gain or loss will be recognized by New Con Edison, Con Edison or
Northeast as a result of the merger.

ACCOUNTING TREATMENT

    The merger will be accounted for as an acquisition of Northeast by New Con
Edison, and will therefore be recorded using purchase accounting.

                                       68
<PAGE>
    Under the purchase method of accounting, New Con Edison will add Northeast's
assets to its own at their fair market value, and any premium paid over and
above the fair market value of Northeast's assets will be reflected as goodwill
on New Con Edison's balance sheet and must be written off against New Con
Edison's future earnings.

DISSENTERS' OR APPRAISAL RIGHTS

    CON EDISON

    Under New York law, because Con Edison common shares are listed on the New
York Stock Exchange, holders of Con Edison common shares will not have any
appraisal or dissenters' rights as a result of the merger.

    NORTHEAST

    Under Massachusetts law and the Northeast declaration of trust, Northeast
shareholders will not have any appraisal or dissenters' rights as a result of
the merger.

WORKFORCE AND EMPLOYEE BENEFIT MATTERS

    CONTINUATION OF AGREEMENTS

    After the completion of the merger, New Con Edison and its subsidiaries will
honor and perform all obligations of the employer under any employment
contracts, agreements, collective bargaining agreements and commitments of Con
Edison and Northeast and their respective subsidiaries existing as of the date
of the merger agreement, provided that New Con Edison will not be prevented from
enforcing such contracts, agreements, collective bargaining agreements or
commitments in accordance with their terms.

    WORKFORCE REDUCTIONS

    Subject to obligations under applicable law and applicable collective
bargaining agreements, for a period of three years following the completion of
the merger, any reductions in the employee workforce of the ongoing operations
of New Con Edison and its subsidiaries will be made on a fair and equitable
basis. New Con Edison will give consideration to previous work history, job
experience and qualifications, without regard to whether employment prior to the
completion of the merger was with Con Edison or its subsidiaries or with
Northeast or its subsidiaries.

    Any employee whose employment is terminated or whose job is eliminated will
be entitled to participate on a fair and equitable basis, as determined by New
Con Edison and its subsidiaries, in the job opportunity and placement programs
offered by New Con Edison or its subsidiaries.

    EMPLOYEE BENEFIT PLANS

    Subject to applicable law and applicable collective bargaining agreements,
New Con Edison and its subsidiaries will give credit under all employee benefit
plans, programs and arrangements to employees for all service prior to the
merger with Con Edison or Northeast or their respective subsidiaries, or any
predecessor employer (to the extent that such credit was given by Northeast or
Con Edison or any of their respective subsidiaries) for all purposes for which
such service was taken into account or recognized by Con Edison or Northeast or
their respective subsidiaries, but not to the extent crediting such service
would result in duplication of benefits (including for benefit accrual purposes
under defined benefit pension plans).

    Subject to applicable law and obligations under applicable collective
bargaining agreements, New Con Edison and its subsidiaries will maintain, for a
period of at least one year after the completion of

                                       69
<PAGE>
the merger, employee compensation, welfare and benefit plans, programs, policies
and fringe benefits as will, in the aggregate, provide to all employees of Con
Edison and Northeast and their respective subsidiaries, who were employees
immediately prior to the completion of the merger, benefits that are no less
favorable than the benefits provided by Con Edison and Northeast and their
subsidiaries to their employees as of the date of the merger agreement.

EFFECT ON AWARDS OUTSTANDING UNDER STOCK PLANS

    CON EDISON

    Under the merger agreement, upon completion of the merger, New Con Edison
will assume each Con Edison employee stock option plan and each outstanding Con
Edison employee stock option. Under the merger agreement, prior to the merger,
Con Edison will adjust the terms of all outstanding Con Edison employee stock
options to provide that the options will constitute options to acquire shares of
New Con Edison common stock, on the same terms and conditions as apply to the
Con Edison employee stock options. As of December 31, 1999, employee stock
options covering 3,451,370 Con Edison common shares were issued and outstanding.

    NORTHEAST

    Under the merger agreement, upon completion of the merger, New Con Edison
will assume each Northeast employee stock option plan and each outstanding
Northeast employee stock option. Under the merger agreement, prior to the
merger, Northeast will adjust the terms of all outstanding Northeast employee
stock options to provide that the options will constitute options to acquire, on
the same terms and conditions as apply to the Northeast employee stock options,
the same number of shares of New Con Edison common stock (rounded down to the
nearest whole share) as the holder of the option would have received in the
merger had the holder exercised the option in full immediately prior to the
merger. The amount of the exercise price per share of New Con Edison common
stock (rounded up to the nearest cent) under any option will be equal to the
aggregate amount of the exercise price for the common shares subject to the
Northeast option divided by the total number of shares of New Con Edison common
stock to be subject to the option. As of December 31, 1999, the number of
Northeast common shares reserved for issuance under such plans was 4,461,838.
See "The Merger--Interests of Northeast's Trustees and Management in the
Merger."

RESALE OF NEW CON EDISON COMMON STOCK

    New Con Edison common stock issued in the merger will not be subject to any
restrictions on transfer arising under the Securities Act of 1933, except for
shares issued to any Con Edison or Northeast shareholder who is, or is expected
to be, an "affiliate" of Con Edison or Northeast, as applicable, for purposes of
Rule 145 under the Securities Act. It is expected that these shareholders will
agree not to transfer any New Con Edison common stock received in the merger
except pursuant to an effective registration statement under the Securities Act
or in a transaction not required to be registered under the Securities Act. The
merger agreement requires each of Con Edison and Northeast to use reasonable
efforts to cause its shareholders who are, or are expected to be, affiliates to
enter into these agreements. This joint proxy statement/prospectus does not
cover resales of New Con Edison common stock received by any person upon
completion of the merger, and no person is authorized to make any use of this
joint proxy statement/prospectus in connection with any resale.

LEGAL PROCEEDINGS RELATED TO THE MERGER

    Two virtually identical Northeast shareholder class action complaints have
been filed in New York Supreme Court for the County of New York on October 13,
1999 and October 19, 1999, respectively.

                                       70
<PAGE>
The complaints name Northeast and the ten members of the Northeast Board of
Trustees as defendants.

    The complaints allege that the members of the Northeast Board of Trustees
breached their fiduciary duties to Northeast's shareholders by agreeing to be
acquired by Con Edison without fully considering other possible offers for
Northeast. The plaintiffs seek equitable relief, including, in each case, an
order that Northeast consider other offers for Northeast. The plaintiffs also
seek to recover costs and attorneys' fees incurred in their class actions.
Northeast believes that the lawsuits are without merit and intends to defend
vigorously against them.

    Both cases have been removed to the U.S. District Court for the Southern
District of New York, where they are now pending. On January 3, 2000, the
defendants moved to dismiss both complaints on various grounds.

    Neither Con Edison nor Northeast believes that the proceedings will have an
adverse effect on Northeast's ability to consummate the merger or any adverse
effect on its business or operations.

                               REGULATORY MATTERS

GENERAL

    A summary of the material regulatory matters affecting approval of the
proposed merger are set forth below. The parties to the merger agreement have
agreed to use their reasonable best efforts to obtain all governmental approvals
and clearances necessary to consummate the merger.

    While we believe that we will receive the regulatory approvals and
clearances for the merger that are summarized below, there can be no assurances
as to the timing of these approvals and clearances or our ability to obtain
these approvals and clearances on satisfactory terms or otherwise. Consummation
of the merger is conditioned upon receipt of final orders from the various
federal and state commissions described below and that the final orders satisfy
conditions described below in "The Merger Agreement--Conditions to the
Completion of the Merger." There can be no assurance that any of these approvals
or clearances will be obtained or, if obtained, will satisfy the conditions
described in such section.

STATE APPROVALS OR FILINGS

    State regulatory approvals and filings will be obtained and made, as
applicable, prior to the consummation of the merger, unless Con Edison and
Northeast otherwise determine, including as follows:

    - The Connecticut Department of Public Utility Control has jurisdiction over
      Northeast's subsidiary, The Connecticut Light and Power Company. Con
      Edison and Northeast filed an application with the Department on January
      12, 2000. The application requests approval for New Con Edison to directly
      control Connecticut Light and Power. The Department will consider whether
      New Con Edison is financially, technologically and managerially suitable
      to control Connecticut Light and Power as well as the ability of
      Connecticut Light and Power to continue to provide safe, adequate and
      reliable service to the public through its plant, equipment, and manner of
      operation were the application to be approved. On February 10, 2000, the
      Department issued a Notice of Hearing and time schedule providing for a
      final decision on May 10, 2000.

    - The Maine Public Utilities Commission has jurisdiction over the indirect
      transfer of control pursuant to the merger of Northeast's subsidiary,
      Public Service Company of New Hampshire, which is regulated as a public
      utility in Maine. On January 19, 2000, Public Service Company filed an
      application with the Commission requesting an order exempting the merger
      under Maine law since Public Service Company has no utility customers in
      Maine.

    - Although the formal approval of the Massachusetts Department of
      Telcommunications and Energy is not required, on January 13, 2000, Con
      Edison and Northeast made an informational filing with the Department
      requesting that the Department confirm that it has no jurisdiction.

    - The New Hampshire Public Utilities Commission has jurisdiction over Public
      Service Company of New Hampshire and two other Northeast subsidiaries, and
      the authority to approve the merger. On January 18, 2000, Con Edison,
      Northeast and the three Northeast subsidiaries propose to file an
      application with the Commission for approval. The Commission must find
      that the merger will not adversely affect the rates, terms, service, or
      operations of the utility subsidiaries and that the merger is lawful,
      proper and in the public interest.

    - Although the formal approval of the New Jersey Board of Public Utilities
      is not required, on January 13, 2000, Con Edison and Northeast made an
      informational filing with the Board.

    - Con Edison and Northeast do not believe that the New York Public Service
      Commission has jurisdiction over the merger but Con Edison and Northeast
      are asking the Commission to

                                       75
<PAGE>
      support the merger and to grant any approvals necessitated by the merger
      such as for changes in accounting and affiliate rules. The standard for
      granting the approvals is that they be in the public interest and that any
      rate changes be just and reasonable. On January 12, 2000 the companies
      filed a petition with the New York Public Service Commission.

    - The Pennsylvania Public Utility Commission has jurisdiction over Con
      Edison's subsidiary, Pike County Light & Power Company, and the
      Commission's approval will be required to consummate the merger. The
      Commission will approve the merger if it finds that the approval is
      necessary or proper for the service, accommodation, convenience or safety
      of the public. On January 20, 2000 an application was filed with the
      Pennsylvania Public Utility Commission.

    - The Vermont Public Service Board has jurisdiction over Public Service
      Company of New Hampshire which is regulated as a public utility in the
      state of Vermont. As a result, the Board must approve the merger. Con
      Edison, Northeast and Public Service Company intend to file an application
      for approval with the Board. Vermont law provides that the Board may grant
      such approval only after notice and opportunity for hearing and upon a
      finding that such an acquisition will promote the public good. The
      companies filed an application with the Vermont Public Serivce Board on
      January 19, 2000.

PUBLIC UTILITY HOLDING COMPANY ACT OF 1935

    Con Edison is currently a holding company exempt from most provisions of the
Public Utility Holding Company Act under Section 3(a)(1) pursuant to Rule 2 of
the Act. Northeast is currently a holding company regulated by and registered
under the Public Utility Holding Company Act. Con Edison and Northeast are
required to obtain Securities and Exchange Commission approval under
Section 9(a)(2) of the Public Utility Holding Company Act in connection with the
merger. Section 9(a)(2) requires an entity owning, directly or indirectly, 5% 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
Securities and Exchange Commission prior to acquiring a direct or indirect
interest in 5% or more of the voting securities of any additional public utility
company. As a result of the merger, Con Edison, a holding company, which
currently holds in excess of 5% of the voting securities of a public utility
within the meaning of the Public Utility Holding Company Act, will be deemed to
have indirectly acquired through New Con Edison all of the common shares of the
subsidiaries of Northeast that are public utility companies within the meaning
of the Public Utility Holding Company Act. Therefore, the approval of the merger
by the Securities and Exchange Commission is required. The companies filed an
application with the Securities and Exchange Commission on January 20, 2000.

    Under the applicable standards of the Public Utility Holding Company Act,
the Securities and Exchange Commission is directed to approve the merger, unless
it finds that:

    - the merger would tend towards detrimental interlocking relations or a
      detrimental concentration of control (creating an overly large and complex
      system, rather than one that affords the opportunity to achieve economies
      of scale and efficiencies and the realization of operating synergies that
      benefit investors and consumers);

    - the consideration to be paid in connection with the merger is not
      reasonable;

    - the merger would unduly complicate the capital structure of New Con
      Edison's holding company system or would be detrimental to the proper
      functioning of New Con Edison's holding company system; or

    - the merger would violate applicable state law.

                                       76
<PAGE>
    To approve the merger, the Securities and Exchange Commission must also find
that the merger would tend towards the development of an integrated public
utility. An integrated public utility is one where, in respect of electric
utility assets:

    - the utility assets are physically interconnected or capable of physical
      interconnection;

    - the utility assets, under normal conditions, may be economically operated
      as a single interconnected and coordinated system;

    - the system must be confined in its operation to a single area or region;
      and

    - the system must not be so large as to impair (considering the state of the
      art and the area or region affected) the advantages of localized
      management, efficient operations, and the effectiveness or regulation.

    New Con Edison will be required to be registered under Section 5 of the
Public Utility Holding Company Act at the effective time of the merger. In that
event, New Con Edison will become subject to the restrictions that the Public
Utility Holding Company Act imposes on registered holding company systems. Among
these are the requirements that certain securities issuances as well as sales
and acquisitions of utility assets or of securities of utility companies and
acquisitions of interests of any other business be approved or authorized by the
Securities and Exchange Commission. The Public Utility Holding Company Act also
limits the ability of registered holding companies to engage in nonutility
ventures and regulates any holding company system service company and the
rendering of services by holding company affiliates to the system's utilities.
The Public Utility Holding Company Act restrictions are not expected to have a
material adverse impact on New Con Edison due to the fact that Northeast is
already regulated by and registered under the Public Utility Holding Company Act
and that Con Edison expects that its current and planned non-utility investments
and transactions will be permitted under the Act. Although the Securities and
Exchange Commission may, pursuant to the Public Utility Holding Company Act,
require the divestiture of any business of the combined company that is not
functionally related as a condition to approval of the merger, Con Edison and
Northeast believe that all of their non-utility activities after completion of
the merger will meet the requirements for retention by a registered holding
company. In conjunction with the registration of New Con Edison as a holding
company under the Public Utility Holding Company Act, the Securities and
Exchange Commission may review the question of whether the system can retain
both gas and electric utility operations. Based on recent orders issued by the
Securities and Exchange Commission under the Public Utility Holding Company Act,
Con Edison and Northeast believe they will be permitted to retain all of their
utility operations.

FEDERAL ENERGY REGULATORY COMMISSION

    Section 203 of the Federal Power Act provides that no public utility may
sell or otherwise dispose of its jurisdictional facilities, directly or
indirectly merge or consolidate its facilities with those of any other person,
or acquire any security of any other public utility without first having
obtained authorization from the Federal Energy Regulatory Commission. Because
Con Edison and Northeast own "jurisdictional facilities" under the Federal Power
Act, the Federal Energy Regulatory Commission's approval under Section 203 is
required before Con Edison and Northeast may consummate the merger. Section 203
provides that the Federal Energy Regulatory Commission is required to grant its
approval if the merger is found to be "consistent with the public interest."

    The Federal Energy Regulatory Commission stated in its 1996 Utility Merger
Policy Statement that, in analyzing a merger under Section 203, it will evaluate
the following criteria:

    - the effect of the merger on competition in wholesale electric power
      markets, utilizing an initial screening approach derived from the
      Department of Justice/Federal Trade Commission Horizontal Merger
      Guidelines to determine if a merger will result in an increase in an
      applicant's market power;

                                       77
<PAGE>
    - the effect of the merger on the applicant's Federal Energy Regulatory
      Commission jurisdictional ratepayers; and

    - the effect of the merger on state and federal regulation of the
      applicants.

    The Federal Energy Regulatory Commission will review these factors to
determine whether the merger is consistent with the public interest. If the
Federal Energy Regulatory Commission finds that the merger would adversely
affect competition, wholesale rates, or regulation, it may, pursuant to the
Federal Power Act, deny approval of the merger or impose remedial conditions
intended to mitigate such effects. Based on recent Federal Energy Regulatory
Commission decisions, Con Edison and Northeast believe that the merger proposal
satisfies all of the Federal Energy Regulatory Commission's criteria for
ensuring that the merger will not have any adverse competitive effects.
Moreover, Con Edison and Northeast have committed in their application to hold
wholesale customers harmless for a period of five years from any merger-related
costs in excess of savings and have committed to follow certain Federal Energy
Regulatory Commission cost allocation policies in order to ensure that the
merger will not impair regulation. The companies filed their application under
Section 203 on January 14, 2000.

NUCLEAR REGULATORY COMMISSION

    The Atomic Energy Act provides that a Nuclear Regulatory Commission license
for nuclear generating facilities may not be transferred or in any manner
disposed of, directly or indirectly, through transfer of control, unless the
Nuclear Regulatory Commission finds that the transfer complies with the Atomic
Energy Act and consents to the transfer. Subsidiaries and affiliates of Con
Edison and Northeast hold licenses for their nuclear generating facilities. On
January 13, Con Edison and Northeast sought approval from the Nuclear Regulatory
Commission of the transfer of control resulting from the merger.

UNITED STATES ANTITRUST LAW

    The Hart-Scott-Rodino Antitrust Improvements Act and the related rules and
regulations prohibit Con Edison and Northeast from completing the merger until
they submit required information to the Antitrust Division of the Department of
Justice and the Federal Trade Commission and until applicable waiting period
requirements have been satisfied. Even after the Hart-Scott-Rodino waiting
period expires or terminates, the Antitrust Division or the Federal Trade
Commission may later challenge the merger on antitrust grounds. Con Edison and
Northeast do not believe that the merger will violate federal antitrust laws. If
the merger is not completed within 12 months after the expiration or earlier
termination of the initial Hart-Scott-Rodino waiting period, Con Edison and
Northeast would be required to submit new information to the Antitrust Division
and the Federal Trade Commission, and a new Hart-Scott-Rodino waiting period
would begin. After the initial pre-merger notification filing with the Antitrust
Division of the Department of Justice and the Federal Trade Commission, Con
Edison received a request for additional information from the Department of
Justice. Con Edison intends to comply with this request and does not expect that
it will have any adverse effect upon the consummation of the merger.

                              THE MERGER AGREEMENT

    THE FOLLOWING SUMMARY OF THE MERGER AGREEMENT IS QUALIFIED BY REFERENCE TO
THE COMPLETE TEXT OF THE MERGER AGREEMENT, WHICH IS INCORPORATED BY REFERENCE
AND ATTACHED AS ANNEX A.

THE MERGER

    Under the merger agreement, Con Edison will merge into New Con Edison, with
New Con Edison being the surviving corporation, and N Acquisition LLC, a
Massachusetts limited liability company and indirect wholly owned subsidiary of
Con Edison, will merge with and into Northeast, with Northeast being the
surviving entity. Upon completion of the merger, the holders of Con Edison
common shares and Northeast common shares will together own all of New Con
Edison's outstanding shares of common stock, New Con Edison will own all of the
assets of Con Edison and Northeast will be a wholly owned subsidiary of New Con
Edison.

TIMING OF CLOSING

    The closing will occur within two business days after the day on which the
last of the conditions set forth in the merger agreement has been satisfied or
waived, unless Con Edison and Northeast agree to a different date or time. We
plan to file certificates of merger with the Department of State of the State of
New York, the Secretary of State of the State of Delaware and the Secretary of
State of the Commonwealth of Massachusetts immediately upon the closing, at
which time the merger will be effective.

MERGER CONSIDERATION

    The merger agreement provides that each Con Edison common share outstanding
immediately prior to the closing of the merger will, at closing, be converted
into one share of New Con Edison common stock. Any Con Edison common shares held
by Con Edison as treasury shares or owned by New Con Edison will be canceled
without any payment for those shares.

    The merger agreement provides that Northeast shareholders may elect to
receive a fraction (the "Exchange Ratio") of a share of New Con Edison common
stock equal to a numerator of $25.00 divided by the weighted average trading
price of a Con Edison common share over 20 trading days randomly selected from
the 40 trading days ending five trading days prior to the closing. However, the
Con Edison share price used to calculate the fraction will not be less than
$36.00 nor greater than $46.00. Also, $1.00 will be added to the numerator if,
on or prior to the closing of the merger, Northeast's subsidiaries enter into
binding agreements to sell to one or more non-affiliated third parties
Northeast's interests in the Millstone Station Unit 2 and Millstone Station Unit
3 nuclear power plant assets, which may or may not include any interest owned by
Public Service Company of New Hampshire, in accordance, in all material
respects, with applicable law and the rules and regulations of the Connecticut
Department of Public Utility Control ("DPUC") for approval of such agreements
and (x) the Utility Operations and Management Unit ("UOMA") of the DPUC has
submitted a formal written recommendation to the DPUC for approval of the
agreements or (y) the DPUC has issued a final order approving the agreements
(the "divestiture condition"). In addition, $.0034 will be added to the
numerator for each day after August 5, 2000 through the day prior to the closing
of the merger.

    In the alternative, holders of Northeast common shares may elect to receive
cash consideration equal to $25.00 per Northeast common share, provided that an
additional $1.00 per share will be payable if, on or prior to the closing of the
merger, Northeast satisfies the divestiture condition and an additional $.0034
per share will be payable for every day after August 5, 2000 through the day
prior to the closing of the merger.

                                       79
<PAGE>
    If the merger closes on or prior to December 31, 2000, and the divestiture
condition has not been satisfied but thereafter and on or prior to December 31,
2000, Northeast satisfies the divestiture condition, then each Northeast
shareholder (whether the shareholder elected stock or cash consideration) will
be entitled to $1.00 per converted Northeast common share to be paid in cash by
New Con Edison. In no event where the merger closes on or prior to December 31,
2000 will Northeast shareholders be entitled to this additional consideration if
the divestiture condition is not satisfied on or prior to December 31, 2000. The
additional consideration will be paid where the merger closes after
December 31, 2000, and the divestiture condition is satisfied prior to the
closing.

    Elections for stock consideration or cash consideration will each be subject
to the allocation and proration procedures described below. Any Northeast common
shares owned by Northeast or New Con Edison will be canceled without any payment
for those shares or rights.

    The auction process with respect to the Millstone Station nuclear power
plant assets began with the filing, in November 1999, of a divestiture plan with
the DPUC. Northeast presently expects to enter into binding agreements for the
sale of the assets in the second or third quarter of 2000, but, due to a pending
motion filed by the Connecticut Office of Consumer Counsel to stay an earlier
DPUC decision relating to the auction process and various other uncertainties,
Northeast is unable to predict the schedule for the required regulatory
approvals or the success of the proposed divestiture. See "Risk Factors--Delays
in the Northeast Nuclear Facilities Divestiture Could Result in Northeast
Shareholders Not Receiving the Additional $1.00 Adjustment to the Merger
Consideration."

ALLOCATION AND PRORATION

    If greater than 50% of the outstanding Northeast common shares eligible to
be converted into merger consideration (the "Maximum Stock Election Number")
elect or are deemed to elect stock consideration, then all holders that elected
or were deemed to have elected to receive stock (the "Requested Stock Amount")
will receive, with respect to each Northeast share for which an election has
been made or deemed made:

    - a number of shares equal to the product of the Exchange Ratio and a
      fraction (the "Stock Proration Factor"), the numerator of which is the
      Maximum Stock Election Number and the denominator of which is the
      Requested Stock Amount; and

    - cash in an amount equal to the product of one minus the Stock Proration
      Factor and $25.00.

    If greater than 50% of the outstanding Northeast common shares eligible to
be converted into merger consideration (the "Maximum Cash Election Number")
elect or are deemed to elect cash consideration, then all holders that elected
or were deemed to have elected to receive cash (the "Requested Cash Amount")
will receive, with respect to each Northeast share for which an election has
been made or deemed made:

    - cash in an amount equal to the product of $25.00 and a fraction (the "Cash
      Proration Factor"), the numerator of which is the Maximum Cash Election
      Number and the denominator of which is the Requested Cash Amount; and

    - a number of shares equal to the product of one minus the Cash Proration
      Factor and the Exchange Ratio.

    As a result of the above-mentioned allocation and proration, the amount of
New Con Edison common stock and cash received by holders of shares of Northeast
may differ from their actual election. If New Con Edison common stock is
over-subscribed by holders of shares of Northeast, those holders who elected to
receive New Con Edison common stock may instead receive part of his or her
consideration in the form of cash. If cash is over-subscribed by holders of
shares of Northeast, those

                                       80
<PAGE>
holders who elected to receive cash may instead receive part of his or her
consideration in the form of shares.

PROCEDURES FOR ELECTION AND EXCHANGE OF NORTHEAST CERTIFICATES; FRACTIONAL
  SHARES

    NORTHEAST SHAREHOLDERS SHOULD NOT RETURN SHARE CERTIFICATES WITH THE
ENCLOSED JOINT PROXY STATEMENT/PROSPECTUS. CON EDISON SHAREHOLDERS WILL NOT BE
REQUIRED TO EXCHANGE THEIR CON EDISON SHARE CERTIFICATES AS A RESULT OF THE
MERGER.

    At least 15 but no more than 60 days prior to the closing of the merger, New
Con Edison, Con Edison and Northeast will mail a form of election to the record
holders of Northeast common shares as of a record date five business days prior
to the mailing. Northeast will use its reasonable best efforts to make the form
of election available to all persons who become record holders of Northeast
common shares during the period between the record date and the closing of the
merger. To be effective, a form of election must be:

    - properly completed;

    - accompanied by the certificates for the Northeast common shares for which
      the election is being made (endorsed in blank or otherwise acceptable for
      transfer on the books of Northeast or by an appropriate guarantee of
      delivery); and

    - received by the exchange and paying agent by 5:00 p.m. New York City time,
      on the fifth business day immediately preceding the closing of the merger.

    If no form of election is received with respect to Northeast common shares,
or if New Con Edison determines that an election was not properly made then:

    - in the event that the Requested Stock Amount exceeds the Maximum Stock
      Election Number, an election for cash will be deemed to have been made;

    - in the event that the Requested Cash Amount exceeds the Maximum Cash
      Election Number, an election for stock will be deemed to have been made;
      and

    - in the event that neither the Maximum Stock Election Number has been
      exceeded by the Requested Stock Amount nor the Maximum Cash Election
      Number has been exceeded by the Requested Cash Amount, an election for
      cash will be deemed to have been made until the point where the Requested
      Cash Amount would exceed the Maximum Cash Election Number, following which
      an election for stock will be deemed to have been made.

    If a deemed election requires elections for both stock and cash, New Con
Edison will to the extent possible allocate the deemed election pro rata among
the Northeast common shares subject to the deemed elections.

    Holders may revoke their elections by filing a written revocation with the
exchange and paying agent before the deadline for submitting elections. All
elections will be automatically revoked if the exchange and paying agent
receives written notice from Con Edison that either the Con Edison merger or the
Northeast merger has been abandoned. Upon revocation, the certificates (or
guarantees of delivery) covered by the elections will be promptly returned.
Revoked elections can only be replaced by a new form of election properly
completed and accompanied by the applicable certificates (endorsed in blank or
otherwise acceptable for transfer on the books of Northeast) that is received by
the exchange and paying agent by the deadline for submitting elections. In the
case of multiple forms of elections received by the exchange and paying agent in
respect of the same Northeast common shares the last dated (or if not dated, the
last received) will govern.

                                       81
<PAGE>
    As soon as reasonably practicable after the completion of the merger, the
exchange and paying agent will mail the following materials to each holder of
record of Northeast common shares whose shares were converted into the right to
receive the consideration to be issued in the merger:

    - a letter of transmittal for use in submitting these shares to the exchange
      and paying agent for exchange; and

    - instructions explaining what the holders must do to effect the surrender
      of Northeast certificates in exchange for the consideration to be issued
      in the merger.

Appropriate adjustments to the foregoing exchange procedures will be made to
account for holders who have previously submitted certificates with their form
of election.

    Northeast holders should complete and sign the letter of transmittal and
return it to the exchange and paying agent together with his or her certificates
in accordance with the instructions.

    After the merger, each certificate that previously represented Northeast
common shares will represent only the right to receive the merger consideration,
including cash for any fractional shares of New Con Edison common stock.

    Holders of certificates previously representing Northeast common shares will
not be paid dividends or distributions on the New Con Edison common stock into
which their shares have been converted with a record date after the merger, and
will not be paid cash for any fractional shares of New Con Edison common stock,
until their certificates are surrendered to the exchange and paying agent for
exchange. When their certificates are surrendered, any unpaid dividends and any
cash instead of fractional shares will be paid without interest.

    In the event of a transfer of ownership of Northeast common shares which is
not registered in the records of the transfer agent of Con Edison or Northeast,
a certificate representing the proper number of shares of New Con Edison common
stock may be issued to a person other than the person in whose name the
surrendered certificate is registered if:

    - the certificate is properly endorsed or otherwise is in proper form for
      transfer, and

    - the person requesting payment and issuance either:

       - pays any transfer or other taxes resulting from the issuance of shares
         of New Con Edison common stock to a person other than the registered
         holder of the certificate, or

       - establishes to the satisfaction of New Con Edison that any taxes have
         been paid or are not applicable.

    All cash paid and shares of New Con Edison common stock issued upon
surrender of certificates representing Northeast common shares, including any
cash paid instead of any fractional shares of New Con Edison common stock, will
be deemed to have been issued and paid in full satisfaction of all rights
relating to those Northeast common shares, as the case may be. Northeast will
remain obligated, however, to pay any dividends or make any other distributions
declared or made by Northeast on Northeast common shares with a record date
before the completion of the merger and which remain unpaid at the completion of
the merger. If Northeast certificates are presented to New Con Edison or the
exchange and paying agent after the completion of the merger, they will be
canceled and exchanged as described above.

    No fractional shares of New Con Edison common stock will be issued upon the
conversion of Northeast common shares.

    As promptly as practicable after the completion of the merger, the exchange
and paying agent will sell on the New York Stock Exchange the excess of the
number of whole shares of New Con Edison common stock delivered to the exchange
and paying agent for exchanges in connection with the merger over the aggregate
number of whole shares of New Con Edison common stock to be distributed to

                                       82
<PAGE>
former Northeast shareholders. The exchange and paying agent will pay to each
former Northeast shareholder a pro rata share of the sale proceeds based upon
the ratio of each shareholder's fractional share interest to the aggregate
amount of fractional share interests to which all former Northeast shareholders
are entitled. Notwithstanding the foregoing, New Con Edison may in the
alternative, at its option, elect to pay to each former Northeast shareholder an
amount in cash equal to the product of each shareholder's fractional share
interest and the closing price for a share of Con Edison common shares as
reported on the New York Stock Exchange Composite Transaction Tape on the
business day immediately prior to the closing of the merger.

<PAGE>
    - receipt of an opinion of counsel that the Northeast merger, taken together
      with the Con Edison merger, will qualify as a transaction described in
      Section 351 of the Internal Revenue Code,

    - absence of a material adverse change with respect to Con Edison (including
      the discovery of, any deterioration in, or any worsening of, any change,

      October 13, 1999) during the period from and after October 13, 1999 until
      closing,

    - all regulatory approvals for the merger being obtained on terms that are

      satisfaction of closing conditions.

    The merger agreement provides that a "material adverse change" or "material

change or effect on

    - the business, assets, properties, condition (financial or otherwise),
      results of operations or prospects of that person and its subsidiaries,
      taken as a whole, or

    - the ability of that person to perform its material obligations under the
      merger agreement or the ability of that person to consummate the merger
      and the other transactions contemplated by the merger agreement.

NO SOLICITATION BY NORTHEAST

    Northeast has agreed that it and its subsidiaries and their trustees,
directors, officers, employees, advisors or other representatives will not,
directly or indirectly:

    - solicit, initiate or encourage (including by way of furnishing
      information), any inquiries or the making of any takeover proposal, as
      described below, involving it, or

    - participate in any discussions or negotiations regarding any takeover
      proposal involving it.

    The merger agreement provides that the term "takeover proposal" means any
inquiry, proposal or offer relating to any acquisition of a business that
constitutes 15% or more of the net revenues, net income or assets of Northeast
and its subsidiaries, taken as a whole, or 15% or more of any class of equity
securities of Northeast or any Northeast subsidiary owning, operating or
controlling a material Northeast business, any tender offer or exchange offer
that would result in any person owning 15% or more of any class of equity
securities of Northeast or any such Northeast subsidiary, or any merger,
consolidation, business combination, recapitalization, liquidation or
dissolution involving Northeast or any such Northeast subsidiary, other than
transactions contemplated by the merger agreement.

    Notwithstanding the foregoing, Northeast may, subject to providing written
notice to Con Edison, for a period of 20 business days following delivery of the
notice, request that a person making a takeover proposal provide information
about itself and its proposal, provided that:

    - the proposal was not solicited by Northeast or otherwise in breach of the
      terms of this covenant, and

    - it is determined in good faith by Northeast's Board of Trustees after
      consultation with its outside counsel and financial advisors:

       - that there is a reasonable possibility that the proposal constitutes a
         superior proposal, and

       - that failing to take such action could reasonably be expected to be a
         breach of its fiduciary duties.

                                       84
<PAGE>
    To the extent that, at any time prior to the expiration of the 20-day period
referred to above, the Northeast Board of Trustees determines that the takeover
proposal constitutes a superior proposal, subject to providing written notice to
Con Edison, Northeast may:

    - furnish information with respect to Northeast and its subsidiaries to the
      person making the proposal pursuant to a confidentiality agreement no less
      favorable to Northeast than the confidentiality agreement between
      Northeast and Con Edison in connection with the merger, and

    - participate in discussions or negotiations regarding the proposal.

    Except as expressly permitted by the merger agreement, neither the Board of
Trustees of Northeast nor any committee thereof will:

    - withdraw or modify in a manner adverse to Con Edison, or propose publicly
      to withdraw or modify in a manner adverse to Con Edison, its approval or
      recommendation of the merger and the merger agreement,

    - approve or recommend, or propose publicly to approve or recommend, any
      takeover proposal, or

    - cause or permit Northeast to enter into any letters of intent, agreement
      in principle, acquisition agreement or other similar agreement related to
      any takeover proposal and Northeast will not enter into any such
      agreement.

    However, the merger agreement provides that, in the event that, prior to
Northeast receiving the approval of its shareholders of the merger agreement,
the Board of Trustees of Northeast determines in good faith that a takeover
proposal constitutes a superior proposal and after consultation with its outside
counsel, that the failure to do so could reasonably be expected to be a breach
of its fiduciary duties, the Board of Trustees of Northeast may terminate the
merger agreement. Any such termination must be prior to the receipt of Northeast
shareholder approval for the merger and at least five business days after
written notice to Con Edison stating that the Northeast Board of Trustees plans
to accept the superior proposal, specifying the terms and conditions of the
proposal and identifying the person making the proposal, provided that,
concurrently with the termination, Northeast will enter into an acquisition
agreement with respect to the superior proposal and pay to Con Edison the
applicable termination fees and the fees and expenses incurred by Con Edison in
connection with the merger. See "--Termination Fees; Reimbursement of Expenses."

    The merger agreement provides that the term "superior proposal" means any
bona fide proposal to acquire, directly or indirectly, for consideration
consisting of cash and/or securities, more than 50% of the voting power of
Northeast's outstanding shares or all or substantially all of Northeast's
assets, and which in the good faith judgment of Northeast's Board of Trustees is
reasonably capable of being completed and is more favorable from a financial
point of view than the transactions contemplated by the merger agreement (taking
into account changes to the merger agreement proposed by Con Edison).

    The merger agreement also provides that Northeast will immediately advise
Con Edison of the receipt of any request for information or of any takeover
proposal, the material terms and conditions of the request or proposal and the
identity of the person making the request or proposal. Under the merger
agreement, Northeast is required to keep Con Edison reasonably informed of the
status and details of any such request or proposal.

TERMINATION

    The merger agreement may be terminated at any time prior to the completion
of the merger:

    (1) by mutual written consent of Con Edison and Northeast,

                                       85
<PAGE>
    (2) by either Con Edison or Northeast if:

       (a) the merger has not been completed by April 13, 2001, unless the
           failure is the result of a breach by the party seeking to terminate;
           provided, however, that date becomes October 13, 2001 if the closing
           of the merger is delayed only because there are legal prohibitions to
           the closing or because regulatory approvals have not been received,

       (b) Con Edison or Northeast shareholders do not approve the merger
           agreement,

       (c) there is a permanent legal prohibition to the merger, provided that
           the party seeking to terminate has used its reasonable best efforts
           to prevent the entry of and to remove the prohibition, or

       (d) the other party breaches the merger agreement in any material respect
           and the breach would result in the failure of a closing condition
           relating to representations or warranties or the performance of
           obligations and has not been or cannot be cured within a reasonable
           period of time, or

    (3) by Con Edison, if Northeast or any of its trustees or officers breaches
       the provisions described in "--No Solicitation by Northeast," or

    (4) by Northeast, if prior to obtaining its shareholder approval of the
       merger agreement:

       - Northeast received an unsolicited takeover proposal satisfying the
         conditions described in "--No Solicitation by Northeast,"

       - the Board of Trustees of Northeast determines in good faith after
         consultation with its outside counsel and financial advisors that there
         is a reasonable possibility that the takeover proposal constitutes a
         superior proposal and that failure to consider the takeover proposal
         could reasonably be expected to be a breach of its fiduciary duties,

       - the Board of Trustees of Northeast determines in good faith that the
         takeover proposal constitutes a superior proposal and, after
         consultation with outside counsel, that failure to terminate the merger
         agreement and accept the superior proposal could reasonably be expected
         to be a breach of its fiduciary duties,

       - Northeast has complied with its other covenants described in "--No
         Solicitation by Northeast," including providing required notices to Con
         Edison,

       - Northeast has paid the required termination and expense reimbursement
         fees described in "--Termination Fees; Reimbursement of Expenses"
         below, and

       - Northeast enters into an acquisition agreement in connection with the
         superior proposal.

    The provisions of the merger agreement relating to brokers fees, the
confidentiality agreement entered into by Con Edison and Northeast and fees and
expenses, including termination fees, will continue in effect notwithstanding
the termination of the merger agreement. However, if the merger agreement is
validly terminated, the agreement will become void without any liability on the
part of any party, unless such party is in willful breach thereof.

    Under the merger agreement, neither Con Edison nor Northeast may terminate
the merger agreement based solely on fluctuation in the price of the other
party's shares.

TERMINATION FEES; REIMBURSEMENT OF EXPENSES

    TERMINATION FEES

    Northeast must pay to Con Edison a termination fee of $110 million, if any
of the following occur:

    (1) a takeover proposal has been made known to Northeast or its subsidiaries
       or has been made directly to the Northeast shareholders or any person has
       publicly announced an intention to

                                       86

                     UNAUDITED PRO FORMA COMBINED CONDENSED
                      FINANCIAL STATEMENTS--NEW CON EDISON

    The unaudited pro forma combined condensed balance sheet as of December 31,
1999 and the unaudited pro forma combined condensed income statement for the
year ended December 31, 1999 combine the historical information of Con Edison
and the pro forma information of Northeast, including Yankee, to give effect to
the merger. The unaudited pro forma combined condensed financial statements have
been prepared to reflect the merger under the purchase method of accounting
where New Con Edison is deemed to have acquired Northeast. Under the purchase
method of accounting, tangible and identifiable intangible assets acquired and
liabilities assumed are recorded at their estimated fair values. The excess of
the purchase price, including estimated fees and expenses related to the merger,
over the net assets acquired is classified as goodwill on the accompanying
unaudited pro forma combined condensed balance sheet. The estimated fair values
and useful lives of assets acquired and liabilities assumed, which were utilized
in the calculation of goodwill, are based on reported balance sheet data and are
subject to final valuation adjustments in accordance with generally accepted
accounting principles.

    The unaudited pro forma financial statements do not reflect the anticipated
cost savings that New Con Edison is able to retain from the elimination of
duplicate corporate and administrative programs in connection with the merger or
operating efficiencies that may result from the merger. The Con Edison and
Northeast pro forma adjustments and the merger are reflected in the unaudited
combined condensed pro forma balance sheet as if they occurred on December 31,
1999. The unaudited pro forma combined condensed statement of income for the
year ended December 31, 1999 assumes that these transactions were completed on
January 1, 1999.

    The unaudited pro forma combined condensed financial statements assume that
50% of the outstanding Northeast common shares were exchanged for cash
consideration of $26.50 and 50% of the outstanding Northeast common shares were
exchanged for .646 shares of New Con Edison common stock. The merger
consideration was determined assuming that the merger would be consummated on
December 31, 2000, the divestiture condition relating to the Millstone nuclear
facilities would be satisfied and that the average price of Con Edison common
shares over the specified period would be $41.00.

    The following unaudited pro forma financial statements should be read in
conjunction with the consolidated historical financial statements and related
notes of Con Edison and Northeast, which are included in the Con Edison and
Northeast Current Reports on Form 8-K filed on February 29, 2000. Con Edison has
provided all the information included below regarding Con Edison and its
subsidiaries. Northeast has provided all the information included below
regarding Northeast and its subsidiaries, as well as regarding Yankee.

    The following unaudited 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 these transactions been completed
on January 1, 1999 or December 31, 1999, as assumed above, nor is the
information necessarily indicative of future financial position or operating
results. Results of operations and financial position in the first year after
consummation could differ significantly from the unaudited pro forma combined
condensed financial statements, which are based on past operations. Future
operations will be affected by various factors including operating performance,
energy market developments and other matters.

    The December 31, 1999 historical financial statements of Con Edison and the
pro forma financial statements of Northeast, including Yankee, were derived from
audited financial statements but do not include all disclosures required by

NOTE D. MERGER CONSIDERATION

    The unaudited pro forma combined condensed financial statements assume that
50% of the outstanding Northeast common shares were exchanged for cash
consideration of $26.50 and 50% of the outstanding Northeast common shares were
exchanged for .646 shares of New Con Edison common stock. We have assumed that
the cash payment to Northeast shareholders will be financed through the issuance
of long-term debt. The merger consideration was determined assuming that the
merger would be consummated on December 31, 2000, the divestiture condition
relating to the Millstore nuclear facilities would be satisfied, the average
trading price of Con Edison common shares over the specified period would be
$41.00 and the value of the fraction of a share of New Con Edison common stock
delivered to Northeast shareholders would remain at $26.50 at the time of
delivery. A closing at December 31, 2000 has been assumed because the date
represents the approximate midpoint as to when Con Edison and Northeast expect
to complete the regulatory approval process for the merger. The satisfaction of
the divestiture condition has been assumed because, although there can be no
assurance, Con Edison and Northeast believe it is more likely than not that the
condition will be satisfied. See "Risk Factors--Uncertainties Relating to
Northeast Nuclear Facilities Divestiture." A Con

Edison share price of $41.00 has been assumed because it represents the midpoint
of the price collar established for Con Edison's share price.

</TABLE>

    If the merger were to close on or before August 5, 2000, the divestiture
condition were not to be satisfied, and the average trading price of Con Edison
common shares was $41.00, the cash payment would be $25.00 per share for 50% of
the Northeast common shares and the exchange ratio would be .610 shares of New
Con Edison common stock per Northeast common share for the other 50% of the
Northeast common shares. In this event, the pro forma earnings per share for the
year ended December 31, 1999 would be $2.25. For additional information on the
effects on pro forma earnings per share from changes to the assumed exchange
ratio based upon different sets of assumptions regarding variables specified in
the merger agreement, see "Unaudited Comparative Per Share Data."

     UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS--NORTHEAST

    The following unaudited pro forma condensed balance sheet as of
December 31, 1999 and the unaudited pro forma combined condensed income
statement for the year ended December 31, 1999 combine the historical
information of Northeast and Yankee to give the effect of the proposed
acquisition of Yankee by Northeast, which is expected to close as early as the
first quarter of 2000. The proposed acquisition is accounted for using the
purchase method of accounting where Northeast is deemed to have acquired Yankee.
Under the purchase method of accounting, tangible and identifiable intangible
assets acquired and liabilities assumed are recorded at their estimated fair
values. The excess of the purchase price, including estimated fees and expenses
related to the merger, over the net assets acquired is classified as goodwill on
the accompanying unaudited pro forma combined condensed balance sheet. The
estimated fair values and useful lives of assets acquired and liabilities
assumed, which were utilized in the calculation of goodwill, are based on
reported balance sheet data and are subject to final valuation adjustments in
accordance with generally accepted accounting principles.

    The unaudited pro forma financial statements do not reflect the anticipated
synergies arising from the acquisition, which are expected to occur after the
acquisition date. For purposes of reflecting the pro forma amounts, the balance
sheet has given effect to the acquisition as if it had occurred at December 31,
1999 and the income statement has given effect to the acquisition as if it had
occurred on January 1, 1999.

    The unaudited pro forma combined condensed financial statements assume that
the total merger consideration paid to Yankee shareholders will be equal to
$479.0 million with 55% of the outstanding Yankee shares each being exchanged
for cash consideration of $45.00 per share and 45% of the outstanding Yankee
shares each being exchanged for a number of Northeast common shares with a value
equal to $45.00. The merger consideration was determined assuming that the
merger would be consummated within six months of Yankee shareholder approval of
the merger agreement. If the closing of the merger has not occurred by the end
of such six-month period, the cash consideration equal to $45.00 per share will
be adjusted upwards by $.005 for each day after such six-month period through
the day prior to the earlier of the closing date or a final termination date
after which there will be no further adjustments. The per share stock
consideration is a number of Northeast shares equal to the cash consideration
divided by the average trading price of Northeast shares over a specified period
prior to the closing of the merger.

    The following unaudited pro forma financial statements should be read in
conjunction with the consolidated historical financial statements and related
notes of Northeast, which are included in the Northeast Current Report on Form
8-K filed on February 29, 2000. Northeast has provided all the information
included below regarding Northeast, Yankee and their respective subsidiaries.

    The following unaudited pro forma combined condensed financial statements
are for illustrative purposes only. They are not necessary indicative of the
financial position or operating results that would have occurred had these
transactions been completed on those dates, as assumed above, nor is the
information necessarily indicative of future financial position or operating
results. Results of operations and financial position in the first year after
consummation could differ significantly from the unaudited pro forma combined
condensed financial statements, which are based on past operations. Future
operations will be affected by various factors including operating performance,
energy market developments and other matters.

    The December 31, 1999 historical financial statements of Northeast and
Yankee were derived from audited financial statements but do not include all
disclosures required by GAAP.

NOTE A. CASH CONSIDERATION

    Cash consideration to be paid to Yankee shareholders will be paid from
proceeds from a Northeast short-term debt offering. Northeast has reflected pro
forma adjustments for the issuance of debt for the full amount payable in cash
(See Note C).

NOTE B. GOODWILL

    Reflects the recognition of the excess amount of the purchase price over the
net assets acquired, calculated as follows:

</TABLE>

NOTE C. SHORT-TERM DEBT

    Reflects the issuance of $263.8 million principal amount of 8% amortizing
notes payable, the proceeds of which may be used to fund the cash consideration
paid to Yankee shareholders.

    An estimate of $2.3 million of debt issuance costs has also been reflected
as a pro forma adjustment related to this debt issuance. As the debt has a
one-year term, the debt issuance costs have been fully amortized in the income
statement.

NOTE D. COMMON SHAREHOLDERS' EQUITY

    Based on the assumption that 55% of the outstanding Yankee shares are each
exchanged for cash consideration of $45.00 per share and 45% of the outstanding
Yankee shares are each exchanged for a number of Northeast common shares with a
value equal to $45.00. The merger consideration was determined assuming that the
merger would be consummated within six months of Yankee shareholder approval of
the merger agreement. If the closing of the merger has not occurred by the end
of such six-month period, the cash consideration equal to $45.00 per share will
be adjusted upwards by $.005 for each day after such six-month period through
the day prior to the earlier of the closing date or a final termination date.
The per share stock consideration is a number of Northeast shares equal to the
cash consideration divided by the average trading price of Northeast shares over
a specified period prior to the closing of the merger.

    Reflects the issuance of 10,496,160 Northeast common shares at an assumed
issuance cost of $20.5625 per share, net of the elimination of Yankee common
shareholders equity.

    In late 1999, Northeast entered into forward share purchase agreements with
two financial institutions. Pursuant to these agreements, the institutions have
purchased in the market and hold approximately 10.0 million Northeast common
shares with an aggregate purchase price equal to $215.0 million. Northeast is
obligated to repurchase these shares from the institutions by December 31, 2000
for the aggregate purchase price of $215.0 million and expects to close the
transactions during the

second half of 2000. If Northeast repurchases the shares with cash prior to the
closing of the merger, then Northeast's common shares outstanding would be
approximately 10.0 million shares less than is reflected in the pro forma
combined condensed financial statements.

NOTE E. MERGER RELATED COSTS

    Northeast and Yankee will incur direct expenses related to the merger,
including accounting and consulting fees. The pro forma adjustments include an
estimate for Northeast's merger-related costs of $8.0 million, which is included
in goodwill. Yankee expects to incur approximately $5.0 million of
merger-related costs, which it will expense as incurred.

NOTE F. AMORTIZATION OF GOODWILL

    Represents the amortization of goodwill, which is not tax deductible, over a
40-year period.

NOTE G: INTEREST EXPENSE, NET

    Represents the interest expense related to the issuance of $263.8 million
principal amount of 8.0% notes payable and the amortization of deferred debt
financing costs over one year.

NOTE H. INCOME TAXES

    Income taxes on the pro forma income statements have been based on a rate of
40%. A tax benefit has not been provided for goodwill, since it is not tax
deductible.

NOTE I. COMMON SHARES OUTSTANDING

    Reflects the issuance of 10,496,160 Northeast common shares at an assumed
issuance cost of $20.5625 at December 31, 1999, net of the elimination of the
Yankee shares outstanding. Does not reflect the expected repurchase in the
second half of 2000 by Northeast of approximately 10.0 million Northeast common
shares pursuant to forward share purchase agreements. For more detail, see
Note D.

and the New Con Edison certificate of incorporation to be in effect on the
effective date of the merger. See "Comparison of Shareholder Rights" on
page 104 and "Where You Can Find More Information" on page 117.

GENERAL

    The total number of authorized shares of capital stock of New Con Edison
consists of 500 million shares of common stock, $.10 par value, and 10 million
shares of preferred stock, $.01 par value.

COMMON STOCK

    Subject to the rights of any holders of preferred stock of New Con Edison,
if any, each holder of common stock will be entitled to cast one vote for each
share held of record on all matters submitted to a vote of the shareholders,
including the election of directors. Holders of common stock will be entitled to
receive dividends or other distributions as declared by the New Con Edison Board
of Directors at its own discretion. The right of the New Con Edison Board of
Directors to declare dividends, however, will be subject to the rights of any
holders of preferred stock, if any, of New Con Edison and certain requirements
of Delaware law.

PREFERRED STOCK

    The New Con Edison Board of Directors has the full authority permitted by
law to issue the preferred stock in one or more classes or series and, with
respect to each class or series, to determine the voting powers, if any, and the
preferences and relative, participating, optional or other special rights, if
any, and any qualifications, limitations or restrictions thereof, of the shares
of any class or series of preferred stock, except that holders of preferred
stock will not be entitled to more than one vote for each share of preferred
stock held. The powers, preferences and relative, participating, optional and
other special rights of each class or series of preferred stock and the
qualifications, limitations or restrictions, if any, thereof may differ from
those of any other classes or series at any time outstanding. Except as
otherwise required by law, as provided in the certificate of incorporation or as
determined by the New Con Edison Board of Directors, holders of preferred stock
will not have any voting rights and will not be entitled to any notice of
shareholder meetings.

                        COMPARISON OF SHAREHOLDER RIGHTS

    Upon completion of the merger, the Con Edison shareholders will receive
shares of common stock of New Con Edison in exchange for their Con Edison common
shares. Upon completion of the merger, the Northeast shareholders will elect
whether to receive either cash or shares of common stock of New Con Edison in
exchange for their Northeast common shares. The following is a summary of the
material differences with respect to the rights of holders of Con Edison common
shares, Northeast common shares and New Con Edison common stock. These
differences arise in part, in the case of Con Edison shareholders, from the
differences between various provisions of New York and Delaware law, and, in the
case of Northeast shareholders, from the differences between various provisions
of Massachusetts and Delaware law, as well as, in each case, differences between
the governing instruments of Con Edison, Northeast and New Con Edison.

    The following description summarizes the material differences which may
affect the rights of Con Edison shareholders and Northeast shareholders, but
does not purport to be a complete statement of all of the differences or a
complete description of the specific provisions referred to in this summary. The
identification of specific differences is not intended to indicate that other
equal or more significant differences do not exist.

    It should be noted that Northeast is a Massachusetts business trust. For
most purposes except those explicitly set forth below, a Massachusetts business
trust is a common law entity governed solely by the company's declaration of
trust, which constitutes a contract among the trustees and shareholders or
beneficiaries of the trust.

CORPORATE GOVERNANCE

    CON EDISON:  The rights of Con Edison shareholders are currently governed by
New York law and the certificate of incorporation and by-laws of Con Edison.
Upon completion of the merger, the rights of Con Edison shareholders who become
New Con Edison shareholders will be governed by Delaware law, the New Con Edison
certificate of incorporation and the New Con Edison by-laws.

    NORTHEAST:  The rights of Northeast shareholders are currently governed by
Massachusetts law and the declaration of trust of Northeast. Upon completion of
the merger, the rights of Northeast shareholders who become New Con Edison
shareholders will be governed by Delaware law, the New Con Edison certificate of
incorporation and the New Con Edison by-laws.

    NEW CON EDISON:  The rights of New Con Edison shareholders will be governed
by Delaware law and the certificate of incorporation and by-laws of New Con
Edison.

AUTHORIZED CAPITAL STOCK

    CON EDISON:  The authorized capital stock of Con Edison consists of
500 million common shares and 6 million preferred shares.

    NORTHEAST:  The authorized capital stock of Northeast consists of 3 million
initial common shares in addition to an unlimited number of common shares
authorized by the affirmative vote of at least a majority in interest of all
shares previously issued and then outstanding of the class or classes of shares
with general voting power. In addition, the authorized capital stock consists of
an unlimited number of preferred shares authorized by the affirmative vote of at
least two-thirds in interest of all shares having general voting power and also
by the vote or consent of the holders of each class of preferred shares
previously issued and then outstanding as may be required by the rights,
privileges, and preferences of each previously established class of preferred
shares.

    NEW CON EDISON:  The authorized capital stock of New Con Edison consists of
500 million shares of common stock and 10 million shares of preferred stock.

NUMBER OF DIRECTORS OR TRUSTEES

    CON EDISON:  Under New York law, a corporation may have one or more
directors on its board of directors. The certificate of incorporation, by-laws
or an action by the shareholders, or an action of the board under the specific
provisions of a by-law adopted by the shareholders, may fix the number of
directors.

    The certificate of incorporation of Con Edison provides that the number of
directors may not be more than sixteen.

    NORTHEAST:  The declaration of trust of Northeast provides that the number
of trustees for each ensuing year will be fixed at each annual meeting of the
shareholders by a majority vote. Ten trustees were authorized at the last annual
meeting of Northeast shareholders.

    NEW CON EDISON:  Under Delaware law, a corporation may have one or more
directors on its board. The number of directors will be fixed by, or in the
manner described in, the by-laws, unless the certificate of incorporation fixes
the number.

    The certificate of incorporation of New Con Edison will specify the initial
number of directors. Under the New Con Edison certificate of incorporation, the
Board of Directors may increase or decrease the number of directors by a
resolution adopted by a majority of the Board of Directors. However, no such
decrease in the number of directors may shorten the term of any incumbent
director. Pursuant to the merger agreement, four of the initial directors of New
Con Edison will be persons who are recommended by Northeast and reasonably
acceptable to Con Edison. The remaining initial directors will be designated by
Con Edison.

CUMULATIVE VOTING

    CON EDISON:  Under New York law, shareholders do not have cumulative voting
rights for the election of directors, unless the corporation's certificate of
incorporation provides for it.

    The certificate of incorporation of Con Edison does not provide for
cumulative voting by shareholders.

    NORTHEAST:  The declaration of trust of Northeast does not provide for
cumulative voting by shareholders.

    NEW CON EDISON:  Under Delaware law, a corporation's certificate of
incorporation may provide for cumulative voting rights for the election of
directors.

    The certificate of incorporation of New Con Edison does not provide for
cumulative voting by shareholders.

VACANCIES ON THE BOARD

    CON EDISON:  Under New York law, the board of directors may fill
newly-created directorships and vacancies, except those resulting from removal
without cause, occurring on the board by a majority vote of the directors then
in office. The certificate of incorporation or by-laws may provide that newly-
created directorships or vacancies will be filled by vote of the shareholders.

    The by-laws of Con Edison only provide that any vacancies in the Board of
Directors may be filled by the majority vote of the remaining directors in
office.

                                      105
<PAGE>
    NORTHEAST:  The declaration of trust of Northeast provides that any
vacancies on the Board of Trustees, resulting from a failure to elect a full
board at a shareholder meeting or from the death, resignation or failure of any
trustee to qualify, may be filled by the majority vote of the remaining trustees
at that time.

    NEW CON EDISON:  Under Delaware law, any vacancy occurring in any office of
the corporation by death, resignation, removal or otherwise will be filled as
set forth in the by-laws. In the absence of a provision in the by-laws
specifying how vacancies will be filled, vacancies and newly-created
directorships may be filled by a majority of the directors then in office. Any
director chosen pursuant to this provision will hold office until the next
election of the class for which the director is chosen to fill a vacancy, and
until his or her successor is elected and qualified.

    The certificate of incorporation of New Con Edison provides that, except as
otherwise set forth in the certificate of incorporation with respect to the
rights of the holders of preferred shares, any vacancy on the Board of Directors
and any newly created directorship resulting from any increase in the authorized
number of directors will be filled only by the majority vote of the directors
then in office. A director chosen to fill a vacancy will hold office until a
successor is duly elected and qualified, or until his or her earlier death,
incapacity, resignation or removal from office.

REMOVAL OF DIRECTORS OR TRUSTEES

    CON EDISON:  Under New York law, shareholders may remove directors for cause
and the certificate of incorporation or a by-law adopted by the shareholders may
provide for such removal by the board of directors, provided, however, that when
the certificate of incorporation provides that the holders of a class or series
of stock, voting as a class, are entitled to elect one or more directors, any
director elected by the holders of that class or series of stock may be removed
only by the vote of the holders of that class or series of stock. If the
certificate of incorporation or by-laws so provide, shareholders may remove a
director without cause.

    The certificate of incorporation of Con Edison provides that a director may
be removed from office only for cause. However, any director elected by the
holders of a series of preferred shares may be removed upon the terms
established by the Board of Directors in connection with the creation of that
particular series of preferred shares.

    NORTHEAST:  The declaration of trust of Northeast does not address the
removal of trustees.

    NEW CON EDISON:  Under Delaware law, any director may be removed, with or
without cause, by the holders of a majority of the shares entitled to vote at an
election of the directors. However, unless the certificate of incorporation
provides otherwise, in the case of a corporation whose board of directors is
classified, shareholders may remove directors only for cause.

    The certificate of incorporation of New Con Edison is silent with respect to
the removal of directors.

VOTE REQUIRED FOR SHAREHOLDER ACTIONS

    CON EDISON:  Under New York law, directors of a corporation will be elected
by a plurality of the votes cast at a shareholder meeting by the holders of
shares entitled to vote in the election, unless otherwise set forth in the
certificate of incorporation. Except as otherwise set forth under New York law,
all other matters brought before a shareholder meeting require the authorization
of a majority of the votes cast in favor or against those matters by the holders
of shares entitled to vote at that meeting.

                                      106
<PAGE>
    The certificate of incorporation and by-laws of Con Edison do not contain
any contrary voting requirements, except as described under "--Business
Combinations" on page 112 of this joint proxy statement/prospectus.

    NORTHEAST:  The declaration of trust of Northeast provides that all matters
properly brought before a shareholder meeting at which a quorum is present will
be decided by the majority vote of the shares present or represented by proxy at
the meeting, except as otherwise set forth in the declaration of trust and the
provisions of any class or classes of preferred shares that may be authorized.
The declaration of trust of Northeast provides that the trustees may only be
elected with the affirmative vote of the holders of a majority of the
outstanding shares with general voting power. As noted below under "--
Amendments to Governing Documents" on page 108 and "--Business Combinations" on
page 112, a vote of two-thirds of all shares outstanding and having voting power
may be required to take certain actions.

    NEW CON EDISON:  Under Delaware law, directors of a corporation will be
elected by a plurality of the votes of the shares present in person or
represented by proxy at a shareholder meeting and entitled to vote in the
election, unless otherwise set forth in the certificate of incorporation or the
by-laws. Except as otherwise required by Delaware law or by the certificate of
incorporation or by-laws, all other matters brought before a shareholder meeting
require the affirmative vote of the majority of shares present in person or
represented by proxy at a shareholder meeting and entitled to vote at that
meeting.

    The by-laws of New Con Edison provide that, except as otherwise required by
the certificate of incorporation or applicable law, the directors of New Con
Edison will be elected by a plurality vote and that all other questions will be
decided by a majority vote of the shareholders. The certificate of incorporation
of New Con Edison and Delaware law do not require a vote other than a plurarity
vote for the election of directors and a majority vote for all other questions
decided by the shareholders.

SHAREHOLDER ACTION BY WRITTEN CONSENT

    CON EDISON:  Under New York law, shareholders may act without a meeting on
any action requiring a vote of shareholders if they have the written consent of
the holders of all shares entitled to vote on the matter or, if the certificate
of incorporation allows, if they have the consent of the holders of outstanding
shares having not less than the minimum number of votes that would be necessary
to authorize or take the action at a meeting at which all shares entitled to
vote were present and voted.

    The certificate of incorporation and the by-laws of Con Edison are silent on
shareholder action by written consent.

    NORTHEAST:  The declaration of trust of Northeast does not address
shareholder action by written consent except with respect to approval of
amendments to the Northeast declaration of trust as described under
"--Amendments to Governing Documents" on page 108.

    NEW CON EDISON:  Under Delaware law, unless otherwise set forth in a
corporation's certificate of incorporation, holders of shares, representing the
minimum number of votes that would be necessary to authorize or take such action
at a meeting at which all shares having a right to vote thereon were present and
voted, may act by written consent.

    The certificate of incorporation of New Con Edison provides that any action
taken by the shareholders must be effected at a duly called annual or special
meeting of the shareholders and may not be effected by the written consent of
the shareholders.

                                      107
<PAGE>
SPECIAL MEETINGS OF SHAREHOLDERS

    CON EDISON:  Under New York law, the board of directors or any other person
authorized by the certificate of incorporation or by-laws of the corporation may
call a special meeting of shareholders.

    The by-laws of Con Edison provide that a shareholder meeting may be held at
any time designated by:

    - the Board of Directors, or

    - shareholders holding one-fourth of the outstanding shares entitled to vote
      at a shareholder meeting.

    NORTHEAST:  The declaration of trust of Northeast provides that special
meetings of the shareholders may be held whenever ordered by:

    - the trustees;

    - the chairman of the Board of Trustees;

    - the president; or

    - whenever requested by the holders of one-tenth in interest of all the
      outstanding shares having the general right to vote at a shareholder
      meeting.

    NEW CON EDISON:  Under Delaware law, special meetings may be called by the
board of directors or by those persons authorized to call a special meeting by
the certificate of incorporation or by-laws of the corporation.

    The by-laws of New Con Edison provide in pertinent part that, except as
otherwise expressly required by the certificate of incorporation or by
applicable law, a special meeting may be called for any purpose by a majority
vote of the entire Board of Directors or by the vote of one-fourth of the
outstanding shares entitled to vote at such meeting. The New Con Edison
certificate of incorporation does not address special meetings of shareholders.

AMENDMENTS TO GOVERNING DOCUMENTS

    CON EDISON:  Under New York law, a corporation may amend its certificate of
incorporation if the amendment contains only provisions that could be lawfully
contained in an original certificate of incorporation filed at the time of the
amendment. Under New York law, an amendment to the certificate of incorporation
must be authorized by a vote of the board of directors, followed by a vote of
the holders of a majority of all outstanding shares entitled to vote at a
shareholder meeting or as otherwise specified in the certificate of
incorporation. New York law also provides that the shareholders may, by a
majority vote, amend, repeal or adopt by-laws, except as otherwise set forth in
the certificate of incorporation. The board of directors may also amend, repeal
or adopt by-laws when permitted by the certificate of incorporation or a
shareholder-adopted by-law.

    The certificate of incorporation of Con Edison provides that the by-laws may
be adopted, amended or repealed by the affirmative vote of a majority of the Con
Edison directors then in office. The certificate of incorporation and by-laws of
Con Edison are otherwise silent with respect to amendments to the certificate of
incorporation and by-laws.

    NORTHEAST:  The declaration of trust of Northeast provides that the trust
may be altered, amended, added to or rescinded by the affirmative vote of at
least two-thirds of the trustees, provided that any such alteration, amendment,
addition or rescission must be approved by the affirmative vote or the written
consent of the holders of at least two-thirds of all shares issued and
outstanding and having

                                      108
<PAGE>
general voting power. However, no alteration, amendment, addition or rescission
adversely affecting the preferences or priorities of any preferred shares will
be effective without the affirmative vote or written consent of the holders of
at least two-thirds of the affected preferred shares.

    NEW CON EDISON:  Under Delaware law, unless the certificate of incorporation
otherwise provides, the certificate of incorporation of a corporation may be
amended upon the vote of the board of directors and the affirmative vote of a
majority of the outstanding stock entitled to vote thereon and a majority of the
outstanding stock of each class entitled to vote thereon as a separate class
(e.g., if the proposed amendment would adversely affect the preferences or
priorities of that class). Also, unless the certificate of incorporation
otherwise provides, the by-laws of a corporation may be amended by the vote of a
majority of the shares entitled to vote thereon that are present in person or by
proxy at a shareholders meeting. The board of directors of a corporation is
authorized to alter, amend, repeal or adopt the by-laws by a majority vote of
the board of directors if so provided in the certificate of incorporation.

    New Con Edison's certificate of incorporation reserves the right to
supplement, amend or repeal any provision of the certificate of incorporation in
the manner prescribed by Delaware law and the certificate of incorporation. The
certificate of incorporation and the by-laws of New Con Edison provide that the
Board of Directors is authorized to alter, amend, repeal or adopt the by-laws by
a majority vote of the entire Board of Directors.

PREEMPTIVE RIGHTS

    CON EDISON:  Under New York law, for corporations created prior to
February 23, 1998, shareholders will have the preemptive right to subscribe to
an additional issue of stock, unless otherwise provided for in the certificate
of incorporation.

    The certificate of incorporation of Con Edison provides that no holders of
shares of any class will have any preemptive rights.

    NORTHEAST:  The declaration of trust of Northeast provides that the holders
of common shares and convertible securities will have preemptive rights with
respect to offerings for cash of common shares or securities convertible into
common shares, except with respect to:

    - common shares, or the grant of rights or options on such shares, to
      trustees, directors, officers, or employees of Northeast or of a
      subsidiary of Northeast, if the issue or grant is approved by the holders
      of common shares at a meeting duly held for such purpose or is authorized
      by and consistent with a plan previously so approved by the holders of
      common shares;

    - common shares issued on the conversion of convertible securities if the
      convertible securities were offered or issued to holders of common shares
      in satisfaction of their preemptive rights or were not subject to
      preemptive rights;

    - common shares and convertible securities offered to shareholders in
      satisfaction of their preemptive rights and not purchased by those
      shareholders;

    - common shares or convertible securities issued pursuant to a plan
      adjusting any rights to fractional shares or fractional interests in order
      to prevent the issue of fractional shares or fractional interests in these
      shares;

    - common shares or convertible securities issued in connection with a merger
      or consolidation or pursuant to an order of a court, unless such order
      provides otherwise;

    - common shares or convertible securities issued in a public offering or
      through an underwriting;

                                      109
<PAGE>
    - common shares or convertible securities released from preemptive rights
      through the affirmative vote or written consent of the holders of at least
      two-thirds of the common shares then outstanding; or

    - common shares or convertible securities held in Northeast's treasury.

    NEW CON EDISON:  Under Delaware law, absent an express provision in a
corporation's certificate of incorporation, a shareholder does not possess
preemptive rights to subscribe to an additional issue of stock.

    The certificate of incorporation of New Con Edison provides that
shareholders will not have any preemptive rights.

INDEMNIFICATION OF DIRECTORS, TRUSTEES AND OFFICERS

    CON EDISON:  Under New York law, a corporation may indemnify any person
made, or threatened to be made, a party to any action by reason of the fact that
he or she was a director or officer of the corporation if the director or
officer acted in good faith for a purpose which he or she reasonably believed to
be in the best interests of the corporation and, in criminal proceedings, if he
or she had no reasonable cause to believe his or her conduct was unlawful.
Indemnification may be provided against judgments, fines, amounts paid in
settlement and reasonable expenses, including attorneys' fees actually and
necessarily incurred as a result of the action.

    In the case of derivative suits, a corporation may not indemnify a director
or officer in the case of:

    - a threatened action, or a pending action which is settled or otherwise
      disposed of, or

    - any claim as to which the person is liable to the corporation, unless and
      only to the extent that the court in which the action was brought, or, if
      no action was brought, any court of competent jurisdiction, determines
      upon application that the person is fairly and reasonably entitled to
      indemnification for a portion of the settlement amount and expenses as the
      court deems proper.

    Indemnification provided under New York law is not exclusive of other
indemnification rights to which a director or officer may be entitled, provided
that no indemnification may 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 or her acts were committed in bad faith or were the result
of active and deliberate dishonesty and were material to the cause of action or
that he or she personally gained a financial profit or other advantage to which
he or she was not legally entitled.

    Any person who has been successful on the merits or otherwise in the defense
of a civil or criminal action or proceeding will be entitled to indemnification.
Except as set forth in the preceding sentence, unless ordered by a court
pursuant to New York law, any indemnification under New York law may be made
only if authorized in the specific case and after a finding that the director or
officer met the requisite standard of conduct:

    - by the disinterested directors if a quorum is available, or

    - if a quorum of disinterested directors is not available, by either the
      board of directors upon the written opinion of independent legal counsel,
      or the shareholders.

    The certificate of incorporation and by-laws of Con Edison provide that,
except to the extent indemnification is not permitted by law, Con Edison will
fully indemnify its directors and officers.

    NORTHEAST:  The declaration of trust of Northeast provides that Northeast
will indemnify each of its present and former trustees and officers against any
loss, liability or expense incurred in proceedings in

                                      110
<PAGE>
which such person may be involved by reason of being or having been an officer
or trustee, except with respect to any matter as to which such person shall have
been finally adjudicated in such proceeding not to have acted in good faith in
the reasonable belief that such person's action was in the best interests of
Northeast. If any such proceeding is disposed of by a compromise payment by any
such trustee or officer, no indemnification payment will be provided unless a
determination is made that such officer or trustee acted in good faith in the
reasonable belief that such person's action was in the best interests of
Northeast. Such determination must be made by either the Board of Trustees by
majority vote of the quorum consisting of trustees who were not parties to such
proceeding, by independent legal counsel to Northeast in a written opinion, or
by the shareholders.

    NEW CON EDISON:  Under Delaware law, a corporation may indemnify its
officers, directors, employees and agents against liabilities and expenses
incurred in proceedings if the person acted in good faith and in a manner he or
she reasonably believed to be in, or not opposed to, the best interests of the
corporation and, with respect to any criminal action, had no reasonable cause to
believe that the person's conduct was unlawful. In the case of derivative
actions, indemnification is limited to expenses and no indemnification may be
made in respect of any claim as to which the person is adjudged liable to the
corporation except as otherwise authorized by a court.

    The by-laws of New Con Edison provide that, except to the extent
indemnification is not permitted by law, New Con Edison will fully indemnify its
directors and officers and provide for the advancement of expenses in connection
with any proceeding. However, New Con Edison will not indemnify a director or
officer who commences any proceeding, unless the commencement of that proceeding
is approved by a majority vote of the disinterested directors.

LIMITATION ON DIRECTOR OR TRUSTEE LIABILITY

    CON EDISON:  Under New York law, a corporation's certificate of
incorporation may contain a provision eliminating or limiting the personal
liability of directors to the corporation or its shareholders for any breach of
duty. However, no provision can eliminate or limit:

    - the liability of any director if a judgment or other final adjudication
      adverse to the director establishes that the director acted in bad faith
      or engaged in intentional misconduct, personally gained a financial profit
      to which he was not legally entitled, or violated certain provisions of
      New York law; or

    - the liability of any director for any act or omission prior to the
      adoption of such provision in the certificate of incorporation.

    The certificate of incorporation and by-laws of Con Edison provide that,
except to the extent limitation of liability is not permitted by law, a director
or officer of Con Edison will not be liable to Con Edison or its shareholders
for damages due to any breach of duty.

    NORTHEAST:  The declaration of trust of Northeast provides that a trustee of
Northeast will not be liable to Northeast or its shareholders for monetary
damages due to any breach of fiduciary duty, except for:

    - breaches of such person's duty of loyalty to Northeast or its
      shareholders;

    - acts or omissions not in good faith or which involve intentional
      misconduct or a knowing violation of law; or

    - any transaction from which such person derived an improper personal
      benefit.

                                      111
<PAGE>
    NEW CON EDISON:  Under Delaware law, a corporation may include in its
certificate of incorporation a provision eliminating the liability of a director
to the corporation or its shareholders for monetary damages for a breach of the
director's fiduciary duties, except liability for any breach of the director's
duty of loyalty to the corporation's shareholders, for acts or omissions not in
good faith or that involve intentional misconduct or knowing violation of law,
under Section 174 of the Delaware Law (which deals generally with unlawful
payments of dividends, stock repurchases and redemptions), and for any
transaction from which the director derived an improper personal benefit.

    The certificate of incorporation of New Con Edison provides that, except to
the extent limitation of liability is not permitted by law, the directors of New
Con Edison will not be personally liable to New Con Edison or its shareholders
for monetary damages due to any breach of fiduciary duty.

BUSINESS COMBINATIONS

    CON EDISON:  Under New York law, a merger, consolidation, disposition of all
or substantially all the assets of a corporation or share exchange requires the
approval of holders of a majority of the outstanding shares entitled to vote,
unless the corporation was in existence on or prior to February 23, 1998 and the
corporation's certificate of incorporation does not expressly provide for the
approval of these transactions by a majority vote, in which case these
transactions must be approved by holders of two-thirds of the outstanding shares
entitled to vote.

    The certificate of incorporation of Con Edison expressly provides that the
approval of the Board of Directors followed by the affirmative vote of a
majority of all outstanding shares of Con Edison entitled to vote will be
required for:

    - a merger or consolidation to which Con Edison is a party, other than a
      merger between Con Edison and a subsidiary of Con Edison for which
      authorization by the shareholders of Con Edison is not required by
      applicable law;

    - the sale, lease, exchange or other disposition of all or substantially all
      the assets of Con Edison; or

    - a binding share exchange to which Con Edison is a party.

    NORTHEAST:  Chapter 182 of the General Laws of Massachusetts provides that a
business trust may merge or consolidate with or into any Massachusetts limited
liability company. The declaration of trust of Northeast does not address
mergers or consolidations. In connection with the merger, Northeast is seeking
approval of certain amendments to the declaration of trust of Northeast
specifically authorizing Northeast to consummate a merger with one or more
Massachusetts limited liability companies in accordance with Chapter 182 upon
the affirmative vote of two-thirds of the shares of Northeast outstanding and
entitled to vote at a meeting of the Northeast shareholders.

    NEW CON EDISON:  Under Delaware law, a merger or consolidation of a
corporation or the sale of all or substantially all of the assets of a
corporation requires authorization by a resolution adopted by the holders of a
majority of the outstanding stock of the corporation entitled to vote, unless
the certificate of incorporation requires a greater vote.

    The certificate of incorporation and by-laws of New Con Edison do not
address business combinations.

DISSENTERS' OR APPRAISAL RIGHTS

    CON EDISON:  Under New York law, a shareholder may dissent from, and receive
payment for the fair value of its shares in the event of, certain mergers,
consolidations, share exchanges and asset transfers. However, in the case of a
merger or consolidation, dissenters' rights are not available:

                                      112
<PAGE>
    - for shares listed on a national securities exchange;

    - for shares designated as a national market system security on an
      interdealer quotation system by the NASD; or

    - to shareholders of the surviving corporation in a merger.

    Because the Con Edison common shares are listed on the New York Stock
Exchange, Con Edison shareholders do not have any appraisal rights.

    NORTHEAST:  The declaration of trust of Northeast does not contain
provisions providing for dissenters' rights. Furthermore, there is no statute in
Massachusetts applicable to common law business trusts that provides for
appraisal rights comparable to the statutory appraisal rights that the
Massachusetts General Laws provides to stockholders of Massachusetts business
corporations who dissent from certain stockholder-approved corporate actions,
including mergers, sale of substantially all corporate property, and any charter
amendment which adversely affects the rights of the dissenting stockholder.

    Until 1991, it was widely believed that there were no common law dissenters'
appraisal rights in Massachusetts. In 1991, however, the Supreme Judicial Court
of Massachusetts held that common law appraisal rights similar to those provided
in the Massachusetts General Laws for Massachusetts business corporation
stockholders were available to dissenting minority stockholders of a
Massachusetts trust company (as opposed to a Massachusetts business trust) in a
case in which an 85% controlling stockholder approved a 1-for-2,500 reverse
stock split that converted all minority share interests into an amount of cash
that the trial court determined was not fair and reasonable. The Court noted
that the Massachusetts trust company statutes do provide statutory appraisal
rights for stockholders of a trust company as to mergers and consolidations, but
not as to the reduction of capital stock. In contrast, the Massachusetts
business trust statute is silent as to appraisal rights in all circumstances.
The Court also distinguished its decision in a 1975 case in which it had held
that there was no common law appraisal right for dissenting stockholders of a
not-for profit golf club corporation that had sold all of its property. In that
decision, the Court had stated that it is "very dubious whether such a right
ever existed in the absence of a statute even with respect to business
corporations."

    Accordingly, it is not clear under what conditions or with respect to what
possible transactions, if any, common law appraisal rights in Massachusetts
might apply to a common law business trust such as Northeast. However, counsel
for Northeast has advised us that the Northeast shareholders would not have
appraisal rights as a result of the merger.

    NEW CON EDISON:  Under Delaware law, a shareholder may dissent from, and
receive payment in cash for the fair value of its shares in the event of,
certain mergers and consolidations. However, under Delaware law and subject to
the following paragraph, appraisal rights are generally not available:

    - for shares listed on a national securities exchange;

    - for shares designated as a national market system security on an
      interdealer quotation system by the NASD;

    - for shares which are held of record by more than 2,000 shareholders; or

    - to shareholders of the surviving corporation if the merger did not require
      for its approval the vote of the shareholders of the surviving
      corporation.

    Notwithstanding the foregoing, appraisal rights are available if
shareholders are required by the terms of the merger agreement to accept for
their shares anything other than:

    - shares of stock of the surviving corporation;

                                      113
<PAGE>
    - shares of stock of another corporation that are listed on a national
      securities exchange, designated as a national market system security as
      described above, or held of record by more than 2,000 shareholders;

    - cash instead of fractional shares of stock; or

    - any combination of the above.

    Appraisal rights are also available under Delaware law in certain other
circumstances including:

    - in certain parent-subsidiary corporation mergers, and

    - in certain circumstances where the certificate of incorporation so
      provides.

    The certificate of incorporation of New Con Edison does not grant additional
appraisal rights.

ANTITAKEOVER STATUTES

    CON EDISON:  Under New York law, a corporation may engage in a business
combination with a 20% shareholder within a five-year period after such
shareholder's stock purchase if:

    - the 20% shareholder's stock purchase was approved by the corporation's
      board of directors before the purchase; or

    - the business combination was approved by the corporation's board of
      directors before the 20% shareholder's stock acquisition date.

    After the expiration of the five-year period, the business combination will
be permitted if:

    - the combination was approved by the affirmative vote of the holders of a
      majority of the outstanding voting stock beneficially owned by
      disinterested shareholders at a meeting called no earlier than five years
      after the 20% shareholder's stock acquisition date; or

    - the price paid to all shareholders meets statutory criteria establishing a
      formula price.

    NORTHEAST: A Massachusetts anti-takeover statute, Chapter 110F of the
Massachusetts General Laws, prohibits any business combination with an
interested shareholder, generally a person who owns or has recently owned at
least 5% of the company's outstanding voting shares, for three years after the
person becomes an interested shareholder unless:

    - prior to the 5% purchase, the board of trustees approves either the 5%
      purchase or the proposed business combination;

    - the interested shareholder owned approximately 90% of the company's voting
      shares after making the 5% purchase which rendered him an interested
      shareholder; or

    - the board of trustees and holders of two-thirds of the non-interested
      shares approve the business combination after the acquiror has become an
      interested stockholder.

    Another Massachusetts anti-takeover statute, Chapter 110D of the
Massachusetts General Laws, regulates the acquisition of control shares. A
control share acquisition occurs when an individual aggregates a number of
shares which, when added to shares already owned, would allow the acquiring
person to vote at least 20% of the company's shares. Under Chapter 110D, shares
acquired in this type of a transaction would have no voting rights unless a
majority of non-interested shareholders specifically voted to grant the
acquiring person voting rights for these shares. In general, the acquiring
person as well as officers and employee-trustees of Northeast are not permitted
to vote on whether these voting rights should be granted.

    The declaration of trust of Northeast does not address antitakeover
regulations or protections.

                                      114
<PAGE>
    NEW CON EDISON:  Under Delaware law, a Delaware corporation is prohibited
from engaging in mergers, dispositions of 10% or more of its assets, and
issuances of stock to and other transactions ("business combinations") with a
person or group that owns 15% or more of the voting stock of the corporation (an
"interested shareholder"), for a period of three years after the interested
shareholder crosses the 15% threshold. These restrictions do not apply in
certain circumstances, including when:

    - prior to the person or group becoming an interested shareholder, the board
      of directors approved the business combination in question or the
      transaction that resulted in the person or group becoming an interested
      shareholder;

    - the interested shareholder acquired at least 85% of the voting stock of
      the corporation (other than stock owned by inside directors and certain
      employee stock plans) in the transaction in which the interested
      shareholder crossed the 15% threshold; or

    - after the person or group became an interested shareholder, the board of
      directors and at least 66 2/3% of the voting stock other than stock owned
      by the interested shareholder approved the business combination.

CONSTITUENCIES STATUTES

    CEI:  Under New York law, in taking action, including any action, without
limitation, which may involve or relate to a change or potential change in the
control of the corporation, directors may consider a number of factors,
including both the short-term and the long-term interests of the corporation and
its shareholders, and the effects that the corporation's actions may have in the
short-term or in the long-term upon:

    - the prospects for potential growth, development, productivity and
      profitability of the corporation;

    - current employees;

    - retired employees and other beneficiaries receiving or entitled to receive
      retirement, welfare or similar benefits under any plan sponsored by, or
      any agreement entered into by, the corporation;

    - customers and creditors; and

    - the ability of the corporation to provide, as a going concern, goods,
      services, employment opportunities and employment benefits and otherwise
      to contribute to the communities in which it does business.

    NORTHEAST:  The declaration of trust of Northeast does not address which
additional factors the Board of Trustees may consider when taking action.

    NEW CON EDISON:  The Delaware General Corporation Law does not include a
provision like the constituencies statute under New York law.

        (i) CANCELATION OF CERTAIN CEI COMMON STOCK. Each share of CEI Common
    Stock that is owned by CEI or the Company shall automatically be canceled

        (ii) CONVERSION OF CEI COMMON STOCK. Subject to Section 2.01(a)(i), each

    nonassessable share of Company Common Stock.

        (iii) CANCELATION OF CEI COMMON STOCK. As of the CEI Effective Time, all
    shares of CEI Common Stock shall no longer be outstanding and shall
    automatically be canceled and retired and shall cease to exist, and each

    (b) At the NU Effective Time, by virtue of the NU Merger and without any

    together with each associated right (each, a "NU RIGHT") under the NU Rights
    Agreement (as defined in

                                       4
<PAGE>
    Section 3.01(x)) that is owned by NU or the Company shall no longer be

        (ii) CONVERSION OF NU COMMON SHARES. Subject to (x) Sections
    2.01(b)(i) and 2.04(e), (y) the allocation and proration provisions set
    forth in 2.03 and (z) adjustment in accordance with Section 2.05(a), each
    issued and outstanding NU Common Share together with each associated NU
    Right shall be converted into the right to receive, at the election of the
    holder thereof, one of the following:

           (A) for each NU Common Share and associated NU Right with respect to
       which an election to receive Company Common Stock ("STOCK CONSIDERATION")
       has been effectively made, and not revoked or lost, or deemed to have
       been made, pursuant to Section 2.02 (a "STOCK ELECTION"), the right to
       receive a number of shares of Company Common Stock equal to the Exchange
       Ratio. If the Closing Date occurs on or prior to August 5, 2000 (the
       "ADJUSTMENT DATE"), the "EXCHANGE RATIO" shall be equal to the quotient
       (rounded to the nearest thousandth, or if there shall not be a nearest
       thousandth, the next higher thousandth) of $25 (the "BASE NUMERATOR")
       divided by the Market Price (as defined below) of CEI Common Stock (the
       "DENOMINATOR"); PROVIDED, HOWEVER, that if (I) the Market Price is less
       than $36, the Denominator shall be $36 and (II) the Market Price is
       greater than $46, the Denominator shall be $46. If the Closing Date is
       after the Adjustment Date, the Exchange Ratio shall be equal to the
       quotient (rounded to the nearest thousandth, or if there shall not be a
       nearest thousandth, the next higher thousandth) of the Adjusted Numerator
       (as defined below) divided by the Denominator. The "ADJUSTED NUMERATOR"
       shall be equal to the Base Numerator increased, for each day after the
       Adjustment Date up to and including the day which is one day prior to the
       Closing Date, by an amount equal to $0.0034 (the Base Numerator and the
       Adjusted Numerator are herein collectively referred to as the
       "NUMERATOR"). The "MARKET PRICE" of CEI Common Stock means the average
       (rounded to the nearest thousandth, or if there shall not be a nearest
       thousandth, the next higher thousandth) of the volume weighted averages
       (rounded to the nearest thousandth, or if there shall not be a nearest
       thousandth, the next higher thousandth) of the trading prices of CEI
       Common Stock on the NYSE (as defined in Section 2.04(e)(ii)), as reported
       by Bloomberg Financial Markets (or such other source as the parties shall
       agree in writing), for the 20 trading days randomly selected by lot by
       CEI and NU together from the 40 consecutive trading days ending on the
       fifth trading day immediately preceding the Closing Date (excluding the
       Closing Date).

           (B) for each such NU Common Share and associated NU Right with
       respect to which an election to receive cash consideration (the "CASH
       CONSIDERATION") has been effectively made, and not revoked or lost, or
       deemed to have been made, pursuant to Section 2.02 (a "CASH ELECTION"),
       the right to receive cash, in an amount equal to $25. If the Closing Date
       is after the Adjustment Date, the Cash Consideration shall be increased,
       for each day after the Adjustment Date up to and including the day which
       is one day prior to the Closing Date, by an amount equal to $0.0034.

        (iii) CANCELATION OF NU COMMON SHARES. As of the NU Effective Time, all
    NU Common Shares together with the associated NU Rights shall no longer be
    outstanding and shall automatically be canceled and retired and shall cease
    to exist, and each holder of a certificate representing any NU Common Shares
    and associated NU Rights shall cease to have any rights with respect
    thereto, except the right to receive the Merger Consideration upon surrender
    of such certificate in accordance with Section 2.04, without interest.

        (iv) CONVERSION OF MERGER LLC EQUITY INTERESTS. All of the equity
    interests in Merger LLC issued and outstanding immediately prior to the NU
    Effective Time (the only holders of which are

                                       5
<PAGE>
    the Company and LLC Holding Sub) shall (A) with respect to such interests
    held by LLC Holding Sub, be automatically canceled and retired and cease to
    exist and (B) with respect to such interests held by the Company, be
    converted into 1,000 duly authorized and issued and fully paid common shares
    of beneficial interest, par value $5.00 per share, of NU.

    (c) The shares of Company Common Stock to be issued pursuant to
Section 2.01(a)(ii) in the case of the CEI Shareholders, and the Stock
Consideration or the Cash Consideration to be issued and paid pursuant to
Section 2.01(b)(ii) in the case of the NU Shareholders, in each case, shall be
referred to, as applicable, as the "MERGER CONSIDERATION".

    (d) At the Effective Time, by virtue of the Mergers and without any action
on the part of any holder of any capital stock of CEI or the Company or any
equity interest of NU, each share of Company Common Stock issued and outstanding
immediately prior to the Effective Time shall be canceled, and no consideration
shall be delivered in exchange therefor.

    SECTION 2.02.  NU SHAREHOLDER ELECTIONS.  (a) Each person who, on or prior
to the Election Date referred to in (b) below, is a record holder of NU Common
Shares and associated NU Rights shall be entitled, with respect to all or any
portion of such shares, to make a Stock Election or a Cash Election on or prior
to such Election Date, on the basis hereinafter set forth.

    (b) The Company, CEI and NU shall prepare and mail, at least 15 but no more
than 60 days prior to the Closing Date, a form of election (the "FORM OF
ELECTION") to the record holders of NU Common Shares and associated NU Rights as
of a record date five business days prior to such mailing, which Form of
Election shall be used by each record holder of NU Common Shares and associated
NU Rights who wishes to elect to receive the Stock Consideration or the Cash
Consideration for any or all of the NU Common Shares and associated NU Rights
held by such holder. NU will use its reasonable best efforts to make the Form of
Election available to all persons who become record holders of NU Common Shares
and associated NU Rights during the period between such record date and the
Closing Date. Any such holder's election to receive the Stock Consideration or
Cash Consideration shall have been properly made only if the Exchange and Paying
Agent (as defined in Section 2.04(a)) shall have received at its designated
office, by 5:00 p.m., New York City time, on the fifth business day immediately
preceding the Closing Date or such other date as may be agreed to by CEI and NU
(the "ELECTION TIME"), a Form of Election properly completed and accompanied by
the Certificates (as defined in Section 2.04(b)) for the NU Common Shares and
associated NU Rights to which such Form of Election relates, duly endorsed in
blank or otherwise in form acceptable for transfer on the books of NU (or by an
appropriate guarantee of delivery), as set forth in such Form of Election.

    (c) Any Form of Election may be revoked by the NU Shareholder who submitted
such Form of Election to the Exchange and Paying Agent only by written notice
received by the Exchange and Paying Agent prior to the Election Time. In
addition, all Forms of Election shall automatically be revoked if the Exchange
and Paying Agent is notified in writing by CEI that either of the Mergers has
been abandoned. If a Form of Election is effectively revoked, the Certificate or
Certificates (or guarantees of delivery, as appropriate) for the NU Common
Shares and associated NU Rights to which such Form of Election relates shall be
promptly returned to the NU Shareholder submitting the same to the Exchange and
Paying Agent. A revoked election cannot be reinstated without valid
resubmission, by the Election Time of a valid Election Form, and a revocation
will not constitute an election for any other consideration. Once a Form of
Election is effectively revoked by a NU Shareholder, such NU Shareholder may
make an effective election to receive the Stock Consideration or the Cash
Consideration only if such NU Shareholder delivers a new Form of Election to the
Exchange and Paying Agent at its designated office, by the Election Time,
together with all other documents required by, and in compliance with the
procedures set forth in or contemplated by, Section 2.02(b). In the case of
multiple Forms of Election received by the Exchange Agent in respect of the same
NU Common Shares and associated NU Rights, the last dated (or, if not dated, the
last received) will govern.

                                       6

    (d) The good faith determination of the Company whether or not elections to
receive the Stock Consideration or Cash Consideration has been properly made or
revoked pursuant to this Section 2.02 with respect to NU Common Shares and
associated NU Rights and when elections and revocations were received by the
Exchange and Paying Agent shall be binding. If no Form of Election is received
with respect to NU Common Shares and associated NU Rights, or if the Company
determines that any election to receive the Stock Consideration or Cash
Consideration was not properly made with respect to NU Common Shares and
associated NU Rights, (i) in the event that Oversubscribed Consideration (as
defined in Section 2.03(a)) exists, an election for the Undersubscribed
Consideration (as defined in Section 2.03(a)) shall be deemed to have been made
with respect to such NU Common Shares and associated NU Rights and such NU
Common Shares and associated NU Rights shall be exchanged in the NU Merger for
the Undersubscribed Consideration pursuant to Section 2.01(b)(ii)(A) or
Section 2.01(b)(ii)(B), as the case may be, and (ii) in the event that no
Oversubscribed Consideration exists, an election for Cash Consideration shall be
deemed to have been made with respect to such Shares and such Shares shall be
exchanged in the NU Merger for Cash Consideration pursuant to
Section 2.01(b)(ii)(B), until the point where such an exchange would make the
Cash Consideration an Oversubscribed Consideration, following which any such NU
Common Shares and associated NU Rights that have not been so exchanged for Cash
Consideration shall be exchanged for Stock Consideration in accordance with
Section 2.01(b)(ii)(A). With respect to any situation in which deemed elections
pursuant to the immediately preceding two sentences require elections for both
Cash Consideration and Stock Consideration to be deemed made, the Company shall
to the extent possible allocate such deemed elections pro rata among such NU
Common Shares and associated NU Rights.

    (e) The Company shall make all computations as to the allocation and the
proration contemplated by Section 2.03 and any such computation shall be
conclusive and binding on the NU Shareholders. CEI and NU may mutually agree to
make such rules as are consistent with this Section 2.02 for the implementation
of the elections provided for herein as shall be necessary or desirable fully to
effect such elections.

    SECTION 2.03.  ALLOCATION AND PRORATION OF CASH AND COMPANY COMMON STOCK.
(a) Notwithstanding anything in this Agreement to the contrary, the number of NU
Common Shares and associated NU Rights to be converted into the right to receive
(i) the Stock Consideration at the Effective Time (the "MAXIMUM STOCK ELECTION
NUMBER") shall not exceed 50% of the NU Outstanding Shares (as defined below)
and (ii) the Cash Consideration at the Effective Time (the "MAXIMUM CASH
ELECTION NUMBER") shall not exceed 50% of the NU Outstanding Shares. If the
aggregate number of NU Common Shares and associated NU Rights in respect of
which elections have been made or deemed made pursuant to Section 2.02 exceeds
the Maximum Stock Election Number or the Maximum Cash Election Number, as the
case may be, the consideration for which such elections have been made or deemed
made shall be referred to herein as the "OVERSUBSCRIBED CONSIDERATION". In the
event that an Oversubscribed Consideration exists, the form of consideration
that is not the Oversubscribed Consideration shall be referred to herein as the
"UNDERSUBSCRIBED CONSIDERATION". "NU OUTSTANDING SHARES" shall mean the NU
Common Shares and associated NU Rights outstanding immediately prior to the NU
Effective Time minus NU Common Shares and associated NU Rights that will be
canceled pursuant to Section 2.01(b)(i).

    (b) If the aggregate number of NU Common Shares and associated NU Rights in
respect of which Stock Elections have been made or deemed made, in each case in
accordance with Section 2.02 (the "REQUESTED STOCK AMOUNT") exceeds the Maximum
Stock Election Number, each holder making or deemed to be making such a Stock
Election shall receive, with respect to each NU Common Share and associated NU
Right for which such a Stock Election has been made or deemed made, (x) such
number of shares of Company Common Stock (together with cash in lieu of
fractional shares determined pursuant to Section 2.04(e)) equal to the product
of (A) the Exchange Ratio and (B) the Stock Proration Factor (as defined below)
and (y) cash in an amount equal to the product of (A) one

                                       7
<PAGE>
minus the Stock Proration Factor and (B) the Cash Consideration. The "STOCK
PRORATION FACTOR" shall be equal to a fraction (expressed as a decimal) the
numerator of which is the Maximum Stock Election Number and the denominator of
which is the Requested Stock Amount.

    (c) If the aggregate number of NU Common Shares and associated NU Rights in
respect of which Cash Elections have been made or deemed made, in each case in
accordance with Section 2.02 (the "REQUESTED CASH AMOUNT"), exceeds the Maximum
Cash Election Number, each holder making or deemed to be making such a Cash
Election shall receive, with respect to each NU Common Share and associated NU
Right for which such a Cash Election has been made or deemed made, (x) cash in
an amount equal to the product of (A) the Cash Consideration and (B) the Cash
Proration Factor (as defined below) and (y) such number of shares of Company
Common Stock (together with cash in lieu of fractional shares determined
pursuant to Section 2.04(e)) equal to the product of (A) one minus the Cash
Proration Factor and (B) the Exchange Ratio. The "CASH PRORATION FACTOR" shall
be equal to a fraction (expressed as a decimal) the numerator of which is the
Maximum Cash Election Number and the denominator of which is the Requested Cash
Amount.

    SECTION 2.04.  EXCHANGE OF CERTIFICATES.  (a) EXCHANGE AND PAYING AGENT.
Promptly following the Effective Time, the Company shall deposit with such bank
or trust company as may be designated by the Company (the "EXCHANGE AND PAYING
AGENT"), for the benefit of the NU Shareholders, for exchange in accordance with
this Article II, through the Exchange and Paying Agent, certificates
representing the shares of Company Common Stock and immediately available funds
in amounts and at the times necessary to pay the Merger Consideration (such
shares of Company Common Stock and funds, together with any dividends or
distributions with respect thereto with a record date after the Effective Time,
being hereinafter referred to as the "EXCHANGE FUND") in exchange for
outstanding NU Common Shares together with the associated NU Rights.

    (b) EXCHANGE PROCEDURES. As soon as reasonably practicable after the
Effective Time, the Exchange and Paying Agent shall mail to each holder of
record of a certificate or certificates which immediately prior to the Effective
Time represented outstanding NU Common Shares together with the associated NU
Rights (the "CERTIFICATES") whose shares were converted into the right to
receive the Merger Consideration pursuant to this Article II, (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 delivery of the
Certificates to the Exchange and Paying Agent and shall be in such form and have
such other provisions as CEI and NU may reasonably specify) and
(ii) instructions for use in surrendering the Certificates in exchange for the
Merger Consideration. Appropriate adjustments to the exchange procedures set
forth in this Section 2.04(b) will be made to account for NU Shareholders who
have previously submitted Certificates pursuant to Section 2.02(b). Upon
surrender of a Certificate for cancelation to the Exchange and Paying Agent,
together with such letter of transmittal, duly executed, and such other
documents as may reasonably be required by the Exchange and Paying Agent, the
holder of such Certificate shall be entitled to receive and the Exchange and
Paying Agent shall deliver, as the case may be, in exchange therefor (i) a
certificate representing that number of whole shares of Company Common Stock
(together with certain dividends or other distributions in accordance with
Section 2.04(c), cash in lieu of fractional shares in accordance with
Section 2.04(e) and any cash payable pursuant to Section 2.03) that such holder
has the right to receive or (ii) the amount of cash that such holder is entitled
to receive, in each case pursuant to the provisions of this Article II, and the
Certificate so surrendered shall forthwith be canceled. In the event of a
transfer of ownership of NU Common Shares and the associated NU Rights that is
not registered in the transfer records of NU, a certificate representing the
proper number of shares of Company Common Stock may be issued to a person other
than the person in whose name the Certificate so surrendered is registered if
such Certificate shall be properly endorsed or otherwise be in proper form for
transfer and the person requesting such issuance shall pay any transfer or other
taxes required by reason of the issuance of shares of Company Common Stock to a
person other than the registered holder of such Certificate or

                                       8
<PAGE>
establish to the satisfaction of the Company that such tax has been paid or is
not applicable. Until surrendered as contemplated by this Section 2.04, each
Certificate shall be deemed at any time after the Effective Time to represent
only the right to receive upon such surrender the Merger Consideration, which
the holder thereof has the right to receive in respect of such Certificate
pursuant to the provisions of this Article II, certain dividends or other
distributions in accordance with Section 2.04(c) and cash in lieu of any
fractional shares of Company Common Stock in accordance with Section 2.04(e). No
interest shall be paid or will accrue on the Merger Consideration or any cash
payable to holders of Certificates pursuant to the provisions of this
Article II.

    (c) DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES. No dividends or other
distributions with respect to Company Common Stock with a record date after the
Effective Time shall be paid to the holder of any unsurrendered Certificate with
respect to the shares of Company Common Stock issuable hereunder in respect
thereof and no cash payment in lieu of fractional shares shall be paid to any
such holder pursuant to Section 2.04(e), and all such dividends, other
distributions and cash in lieu of fractional shares of Company Common Stock
shall be paid by the Company to the Exchange and Paying Agent and shall be
included in the Exchange Fund, in each case until the surrender of such
Certificate in accordance with this Article II. Subject to the effect of
applicable escheat or similar laws, following surrender of any such Certificate
there shall be paid to the holder of the certificate representing whole shares
of Company Common Stock issued in exchange therefor, without interest, (i) as
soon as practicable after such surrender, the amount of dividends or other
distributions with a record date after the Effective Time theretofore paid with
respect to such whole shares of Company Common Stock and the amount of any cash
payable in lieu of a fractional share of Company Common Stock to which such
holder is entitled pursuant to Section 2.04(e) 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 such surrender and with a payment date
subsequent to such surrender payable with respect to such whole shares of
Company Common Stock.

    (d) NO FURTHER OWNERSHIP RIGHTS IN CEI COMMON STOCK OR NU COMMON SHARES. All
certificates which immediately prior to the Effective Time represented
outstanding shares of CEI Common Stock shall thereafter represent a like number
of shares of Company Common Stock and, notwithstanding anything noted thereon,
no holder thereof shall have any rights pertaining to shares of CEI Common
Stock, SUBJECT, HOWEVER, to CEI's obligation to pay any dividends or make any
other distributions with a record date prior to the Effective Time that may have
been declared or made by CEI on such shares and which remain unpaid at the
Effective Time, and all shares of Company Common Stock issued upon the surrender
for exchange of Certificates in accordance with the terms of this Article II
(including any cash paid pursuant to this Article II) shall be deemed to have
been issued (and paid) in full satisfaction of all rights pertaining to the NU
Common Shares and the associated NU Rights theretofore represented by such
Certificates, SUBJECT, HOWEVER, to NU's obligation to pay any dividends or make
any other distributions with a record date prior to the Effective Time that may
have been declared or made by NU on such shares and which remain unpaid at the
Effective Time, and there shall be no further registration of transfers on the
stock transfer books of CEI or NU of the shares of CEI Common Stock or the NU
Common Shares and the associated NU Rights, respectively, that were outstanding
immediately prior to the Effective Time. If, after the Effective Time,
Certificates are presented to the Company, CEI, NU or the Exchange and Paying
Agent for any reason, they shall be canceled and exchanged as provided in this
Article II, except as otherwise provided by Applicable Law.

    (e) NO FRACTIONAL SHARES. (i) No certificates or scrip representing
fractional shares of Company Common Stock shall be issued upon the surrender for
exchange of Certificates, no dividend or distribution of the Company shall
relate to such fractional share interests and such fractional share interests
will not entitle the owner thereof to vote or to any rights of a shareholder of
the Company.

                                       9

    (ii) As promptly as practicable following the Effective Time, the Exchange
and Paying Agent shall determine the excess of (A) the number of shares of
Company Common Stock delivered to the Exchange and Paying Agent by the Company
pursuant to Section 2.04(a) over (B) the aggregate number of whole shares of
Company Common Stock to be distributed to former NU Shareholders pursuant to
this Article II (such excess being herein called the "EXCESS SHARES"). Following
the Effective Time, the Exchange and Paying Agent shall, on behalf of former NU
Shareholders, sell the Excess Shares at then-prevailing prices on the New York
Stock Exchange, Inc. (the "NYSE"), all in the manner provided in
Section 2.04(e)(iii).

    (iii) The sale of the Excess Shares by the Exchange and Paying Agent shall
be executed on the NYSE through one or more member firms thereof and shall be
executed in round lots to the extent practicable. The Exchange and Paying Agent
shall use reasonable best efforts to complete the sale of the Excess Shares as
promptly following the Effective Time as, in the Exchange and Paying Agent's
sole judgment, is practicable consistent with obtaining the best execution of
such sales in light of prevailing market conditions. Until the net proceeds of
such sale or sales have been distributed to the holders of Certificates formerly
representing NU Common Shares and the associated NU Rights the Exchange and
Paying Agent shall hold such proceeds in trust for such holders (the "COMMON
SHARES TRUST"). The Company shall pay all commissions, transfer taxes and other
out-of-pocket transaction costs, including the expenses and compensation of the
Exchange and Paying Agent incurred in connection with such sale of the Excess
Shares. The Exchange and Paying Agent shall determine the portion of the Common
Shares Trust to which each former NU Shareholder is entitled, if any, by
multiplying the amount of the aggregate net proceeds composing the Common Shares
Trust by a fraction, the numerator of which is the amount of the fractional
share interest to which such former NU Shareholder is entitled and the
denominator of which is the aggregate amount of fractional share interests to
which all former NU Shareholders are entitled.

    (iv) Notwithstanding the provisions of Section 2.04(e)(ii) and (iii), the
Company may elect at its option, exercised prior to the Effective Time, in lieu
of the issuance and sale of Excess Shares and the making of the payments
hereinabove contemplated, to pay each former NU Shareholder an amount in cash
equal to the product obtained by multiplying (A) the fractional share interest
to which such former NU Shareholder would otherwise be entitled by (B) the
closing price for a share of CEI Common Stock as reported on the NYSE Composite
Transaction Tape (as reported by Bloomberg Financial Markets, or, if not
reported thereby, any other authoritative source) on the business day
immediately prior to the Closing Date, and, in such case, all references herein
to the cash proceeds of the sale of the Excess Shares and similar references
shall be deemed to mean and refer to the payments calculated as set forth in
this Section 2.04(e)(iv).

    (v) As soon as practicable after the determination of the amount of cash, if
any, to be paid to holders of Certificates formerly representing NU Common
Shares and the associated NU Rights with respect to any fractional share
interests, the Exchange and Paying Agent shall make available such amounts to
such holders of Certificates formerly representing NU Common Shares and the
associated NU Rights subject to and in accordance with the terms of
Section 2.04(c).

    (f) TERMINATION OF EXCHANGE FUND. Any portion of the Exchange Fund which
remains undistributed to the holders of the Certificates for six months after
the Effective Time shall be delivered to the Company, upon demand, and any
holders of the Certificates who have not theretofore complied with this
Article II shall thereafter look only to the Company for payment of their claim
for Merger Consideration, any dividends or distributions with respect to Company
Common Stock, and any cash in lieu of fractional shares of Company Common Stock.

    (g) NO LIABILITY. None of CEI, NU, the Company, Merger LLC or the Exchange
and Paying Agent shall be liable to any person in respect of any shares of
Company Common Stock, any dividends or distributions with respect thereto, any
cash in lieu of fractional shares of Company Common Stock or

                                       10
<PAGE>
any cash from the Exchange Fund, in each case delivered to a public official
pursuant to any applicable abandoned property, escheat or similar law. If any
Certificate shall not have been surrendered prior to two years after the
Effective Time (or immediately prior to such earlier date on which any Merger
Consideration, any dividends or distributions payable to the holder of such
Certificate or any cash payable to the holder of such Certificate formerly
representing NU Common Shares and the associated NU Rights pursuant to this
Article II, would otherwise escheat to or become the property of any
Governmental Entity (as defined in Section 3.01(d)), any such Merger
Consideration, dividends or distributions in respect of such Certificate or such
cash shall, to the extent permitted by Applicable Law, become the property of
the Company, free and clear of all claims or interest of any person previously
entitled thereto.

    (h) INVESTMENT OF EXCHANGE FUND AND COMMON SHARES TRUST. The Exchange and
Paying Agent shall invest any cash included in the Exchange Fund and Common
Shares Trust, as directed by the Company, on a daily basis. Any interest and
other income resulting from such investments shall be paid to the Company.

    (i) LOST CERTIFICATES. If any Certificate shall have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the person claiming
such Certificate to be lost, stolen or destroyed and, if required by the
Company, the posting by such person of a bond in such reasonable amount as the
Company may direct as indemnity against any claim that may be made against it
with respect to such Certificate, the Exchange and Paying Agent shall issue in
exchange for such lost, stolen or destroyed Certificate, the Merger
Consideration and, if applicable, any unpaid dividends and distributions on
shares of Company Common Stock deliverable in respect thereof and any cash in
lieu of fractional shares, in each case pursuant to this Agreement.

    (j) WITHHOLDING RIGHTS. The Company shall be entitled to deduct and withhold
from the consideration otherwise payable to any CEI Shareholder or any NU
Shareholder, as the case may be, pursuant to this Agreement such amounts as may
be required to be deducted and withheld with respect to the making of such
payment under the Code, or under any provision of state, local or foreign tax
law. To the extent that amounts are so withheld and paid over to the appropriate
taxing authority, the Company will be treated as though it withheld an
appropriate amount of the type of consideration otherwise payable pursuant to
this Agreement to any CEI Shareholder or any NU Shareholder, as the case may be,
and if such consideration is not cash, sold such consideration for an amount of
cash equal to the fair market value of such consideration at the time of such
deemed sale, and paid such cash consideration or proceeds to the appropriate
taxing authority.

    SECTION 2.05.  ADJUSTMENTS FOR SALE OF CERTAIN NU NUCLEAR
FACILITIES.  (a) CERTAIN ADJUSTMENTS TO THE STOCK CONSIDERATION AND THE CASH
CONSIDERATION. If after the date of this Agreement and on or prior to the
Closing Date, (i) the relevant NU Subsidiaries have entered into one or more
legally binding agreements providing for the sale to one or more third parties
which are not Affiliates of NU of both Millstone Station 2 and Millstone Station
3, which agreements need not include any interest therein owned by Public
Service Company of New Hampshire ("PSNH"), in accordance, in all material
respects, with applicable legislation and the rules, regulations and policies of
DPUC (existing as of, or established after, the date of this Agreement) for
approval of such agreements (the "NU NUCLEAR FACILITIES SALES AGREEMENTS") and
(ii) the Utility Operations and Management Unit ("UOMA") of DPUC (as defined in
Section 3.01(d)(iii)) has submitted a formal written recommendation to DPUC for
approval of the NU Nuclear Facilities Sales Agreement, or the DPUC shall have
issued a Final Order (as defined in Section 6.02(e)) approving such NU Nuclear
Facilities Sales Agreements, then (A) in the case of each NU Common Share and
associated NU Right with respect to which a Stock Election has been effectively
made, and not revoked or lost, or deemed to have been made, pursuant to
Section 2.02, the Numerator shall be increased by an amount equal to $1.00 and
(B) in the case of each NU Common Share and associated NU Right with respect to
which a Cash Election has been

                                       11
<PAGE>
effectively made, and not revoked or lost, or deemed to have been made, pursuant
to Section 2.02, the Cash Consideration shall be increased by an amount equal to
$1.00.

    (b) CERTAIN CONTINGENT VALUE RIGHTS. If the relevant NU Subsidiaries have
not entered into the NU Nuclear Facilities Sales Agreements on or prior to the
Closing Date, and the Closing Date occurs on or prior to December 31, 2000, each
NU Shareholder shall receive (in addition to the Stock Consideration or Cash
Consideration otherwise received by such NU Shareholder in the NU Merger) for
each NU Common Share and associated NU Right, one non-transferable contingent
value right issued by the Company (each, a "CVR") entitling the holder thereof
to payment of $1.00 in cash if, on or prior to December 31, 2000, (i) the
relevant NU Subsidiaries have entered into the NU Nuclear Facilities Sales
Agreements and (ii) UOMA has submitted a formal written recommendation to DPUC
for approval of such NU Nuclear Facilities Sales Agreements or the DPUC shall
have issued a Final Order approving such NU Nuclear Facilities Sales Agreements.
If any CVRs are issued and as of 11:59 p.m. Eastern Standard Time on
December 31, 2000 (i) the relevant NU Subsidiaries have not entered into the NU
Nuclear Facilities Sales Agreements or (ii) UOMA has not submitted a formal
written recommendation to DPUC for approval of such NU Nuclear Facilities Sales
Agreements and the DPUC shall not have issued a Final Order approving such NU
Nuclear Facilities Sales Agreements, then the CVRs shall expire. In the event
that the Company is required to issue any CVRs, CEI and NU shall negotiate in
good faith the other terms and conditions of such CVRs.

    SECTION 2.06.  CERTAIN ADJUSTMENTS.  If after the date hereof and on or
prior to the Closing Date, the outstanding shares of CEI Common Stock (and CEI
Common Stock held by CECONY) shall be changed into a different number of shares
by reason of any reclassification, recapitalization, split-up, combination or
exchange of shares, or any dividend payable in stock or other securities is
declared thereon with a record date within such period, or any similar event
shall occur, the Merger Consideration will be adjusted accordingly to provide to
the holders of CEI Common Stock (including CECONY) and NU Common Shares and the
associated NU Rights, respectively, the same economic effect as contemplated by
this Agreement prior to such reclassification, recapitalization, split-up,
combination, exchange or dividend or similar event.

                                  ARTICLE III
                         REPRESENTATIONS AND WARRANTIES

    SECTION 3.01.  REPRESENTATIONS AND WARRANTIES OF NU.  Except as set forth on
the Disclosure Schedule delivered by NU to CEI prior to the execution of this
Agreement (the "NU DISCLOSURE SCHEDULE") and making reference to the particular
subsection of this Agreement to which exception is being taken, NU represents
and warrants to CEI as follows:

    (a) ORGANIZATION, STANDING AND CORPORATE POWER. NU is a voluntary
association duly organized, validly existing and in good standing under the laws
of the Commonwealth of Massachusetts, each subsidiary of NU (each a "NU
SUBSIDIARY") is a corporation or other legal entity duly organized, validly
existing and in good standing under the laws of the jurisdiction in which it is
organized and each of NU and the NU Subsidiaries has the requisite corporate or
other power, as the case may be, and authority to carry on its business as now
being conducted, except, as to the NU Subsidiaries, for those jurisdictions
where the failure to be so organized, existing or in good standing would not
have, individually or in the aggregate, a Material Adverse Effect (as defined in
Section 8.03) on NU. The respective articles of incorporation and by-laws or
other organizational documents of each NU Subsidiary, in each case as amended
through the date of this Agreement, do not contain any provision limiting or
otherwise restricting the ability of NU to control each such NU Subsidiary.

    (b) SUBSIDIARIES. Section 3.01(b) of the NU Disclosure Schedule sets forth,
as of the date of this Agreement, a complete list of (i) the NU Subsidiaries and
specifies each of NU's Subsidiaries that is a "public-utility company", a
"holding company", a "subsidiary company", an "affiliate" of any public-

                                       12

utility company, an "exempt wholesale generator" or a "foreign utility company"
within the meaning of Section 2(a)(5), 2(a)(7), 2(a)(8), 2(a)(11), 32(a)(1) or
33(a)(3) of the Public Utility Holding Company Act of 1935, as amended
("PUHCA"), respectively, or a "public utility" within the meaning of
Section 201(e) of the Federal Power Act (the "POWER ACT") and (ii) all other
entities in which NU has an aggregate equity investment in excess of
$5 million.

    (c) CAPITAL STRUCTURE. NU is authorized to issue up to 225,000,000 NU Common
Shares and no shares with a preference as to dividends or in liquidation or
otherwise over the NU Common Shares have been authorized or issued. At the close
of business on October 12, 1999, 137,237,564 NU Common Shares were issued and
outstanding, including 3,746 NU Common Shares were held by NU in its treasury.
During the period from October 12, 1999 through the date of this Agreement, NU
has not issued any NU Common Shares or placed any NU Common Shares in its
treasury (except, in each case, as required by the NU Stock Plans (as defined
below)). As of the date of this Agreement, (i) other than pursuant to the NU
Stock Plans (as defined below) and the NU Rights Plan, no securities of NU
convertible into or exchangeable or exercisable for shares of equity interest of
NU were outstanding; (ii) other than pursuant to the NU Stock Plans and the NU
Rights Plan, no warrants, calls, options or other rights to acquire from NU or
any NU Subsidiary, and no obligation of NU or any NU Subsidiary to issue, any
shares of equity interest of NU were outstanding; and (iii) no bonds,
debentures, notes or other indebtedness of NU or any NU Subsidiary having the
right to vote on matters presented to shareholders of NU or such NU Subsidiary
(or convertible into securities of NU or any NU Subsidiary having the right to
vote on matters presented to shareholders of NU or such NU Subsidiary) ("NU
VOTING DEBT") were outstanding. Section 3.01(c) of the NU Disclosure Schedule
sets forth a list and description of each plan or program of NU or any NU
Subsidiary pursuant to which securities or options to purchase securities of NU
or any NU Subsidiary may be issued or delivered (collectively, the "NU STOCK
PLANS"). Section 3.01(c) of the NU Disclosure Schedule sets forth a complete and
correct list, as of the date of this Agreement, of the number of NU Common
Shares subject to employee stock options to purchase or receive NU Common Shares
and the exercise prices thereof and a list of NU Common Shares reserved for
issuance relating to other rights to purchase or receive NU Common Shares
granted under the NU Stock Plans (collectively with such employee stock options,
the "NU STOCK OPTIONS"). All the outstanding shares of equity interest of NU and
all the outstanding shares of capital stock of, or other equity interests in,
each of the NU Subsidiaries have been validly issued and are fully paid and
nonassessable and (except for any series of preferred stock of any NU Subsidiary
held by public shareholders) all the outstanding shares of capital stock of, or
other equity interests in, each of the NU Subsidiaries are, as of the date of
this Agreement, owned directly or indirectly by NU, free and clear of all
pledges, claims, liens, charges, encumbrances and security interests of any kind
or nature whatsoever (collectively, "LIENS") and free of any other restriction
(including any restriction on the right to vote, sell or otherwise dispose of
such capital stock or other ownership interests) and there are no outstanding
subscriptions, options, calls, contracts, voting trusts, proxies or other
commitments, understandings, restrictions, arrangements, rights or warrants,
including any right of conversion or exchange under any outstanding security,
instrument or other agreement, obligating any such NU Subsidiary to issue,
deliver or sell, or cause to be issued, delivered or sold, additional shares of
its equity interest or obligating it to grant, extend or enter into any such
agreement or commitment.

    (d) AUTHORITY; NONCONTRAVENTION; STATUTORY APPROVALS. (i) AUTHORITY. NU has
all requisite power and authority to enter into this Agreement and, subject to
the NU Shareholder Approval (as defined in Section 3.01(o)) and the applicable
NU Statutory Approvals (as defined in Section 3.01(d)(iii)), to consummate the
transactions contemplated by this Agreement. The execution and delivery of this
Agreement by NU and the consummation by NU of the transactions contemplated by
this Agreement have been duly authorized by all necessary action on the part of
NU, subject, in the case of the NU Merger and the Trust Agreement Amendments, to

by each of the other parties hereto, constitutes the legal, valid and binding
obligation of NU, enforceable against NU in accordance with its terms.

    (ii) NONCONTRAVENTION. The execution and delivery of this Agreement by NU do
not, and the consummation of the transactions contemplated by this Agreement and
compliance with the provisions of this Agreement will not, conflict with, or
result in any violation of, or constitute a breach or default (with or without
notice or lapse of time, or both) under, or result in the termination of, or
give rise to a right of termination, cancelation, modification or acceleration
of, any obligation or loss of a benefit under, or result in the creation of any
Lien upon any of the properties or assets of NU or any NU Subsidiary under (any
such conflict, violation, breach, default, termination, right of termination,
modification, cancelation or acceleration, loss or creation is referred to

filings, including with respect to communications systems, zoning, name change,
occupancy and similar routine regulatory approvals).

    (iii) STATUTORY APPROVALS. No consent, approval, order, permit or

    (e) REPORTS AND FINANCIAL STATEMENTS. The filings (other than immaterial
filings) required to be made by NU and the NU Subsidiaries under the Securities
Act of 1933, as amended (the "SECURITIES ACT"), the Exchange Act, PUHCA, the
Power Act, the Atomic Energy Act or applicable state public utility laws and
regulations have been filed with the SEC, FERC, the NRC or the appropriate state
public utilities commission, as the case may be, including all forms,
statements, reports, tariffs, contracts, agreements (oral or written) and all
documents, exhibits, amendments and supplements appertaining thereto required to
be filed with such commission. As of their respective dates, the reports,
schedules, forms, statements and other documents (including exhibits and all
other information incorporated therein) required to be filed by NU or any NU
Subsidiary with the SEC since January 1, 1997 (the "NU SEC DOCUMENTS") complied
in all material respects with the requirements of the Securities Act, the
Exchange Act or PUHCA, as the case may be, and the rules and regulations of the
SEC promulgated thereunder applicable to such NU SEC Documents, and none of the
NU SEC Documents when filed contained any untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they were made, not misleading. The financial statements of NU included in the
NU SEC Documents (the "NU FINANCIAL STATEMENTS") comply as to form, as of their
respective dates of filing with the SEC, in all material respects with
applicable accounting requirements and the published rules and regulations of
the SEC with respect thereto, have been prepared in accordance with United
States generally accepted accounting principles ("GAAP") (except, in the case of
unaudited statements, as permitted by Form 10-Q of the SEC) applied on a
consistent basis during the periods involved (except as may be indicated in the
notes thereto) and fairly present in all material respects the consolidated
financial position of NU and its consolidated subsidiaries as of the dates
thereof and the consolidated results of their operations and cash flows for the
periods then ended (subject, in the case of unaudited statements, to normal
recurring year-end audit adjustments).

    (f) ASSETS AND PROPERTIES. NU and the NU Subsidiaries have good and
sufficient title to all properties and assets reflected on the consolidated
balance sheet of NU and its consolidated subsidiaries included in the NU
Financial Statements or thereafter acquired (except as sold or otherwise
disposed of since the date of such balance sheet (A) with respect to any such
sale or disposition prior to the date of this Agreement or (B) with respect to
any such sale or disposition from and after the date of this Agreement, in
compliance with clause (e) of Section 4.01) in each case free

                                       15
<PAGE>
and clear of all Liens (other than Liens under any mortgage indenture of any NU
Subsidiary applicable to the assets of such NU Subsidiary), except where the
failure to have good title free and clear of all Liens to any such properties or
assets would not have, individually or in the aggregate, a Material Adverse
Effect on NU. The tangible assets of NU and the NU Subsidiaries are in an
adequate state of maintenance and repair (except for ordinary wear and tear),
except where their failure to be in such state of maintenance and repair would
not have, individually or in the aggregate, a Material Adverse Effect on NU.

    (g) FRANCHISES. NU and the NU Subsidiaries own or have sufficient rights and
consents to locate and use under existing franchises, permits, easements,
leases, and license agreements (the "NU PERMITS") all properties, rights and
assets necessary for the conduct of their business and operations as currently
conducted, except where the failure to own or have sufficient rights to such
properties, rights and assets would not have, individually or in the aggregate,
a Material Adverse Effect on NU. To the knowledge (as defined in Section 8.03)
of NU, no other private corporation has as of the date of this Agreement
commenced, or, without obtaining a certificate of public convenience and
necessity from the applicable state utility commission, can commence, operations
distributing electricity to the general public along and across public streets
and ways in any part of the territories now served by NU or any NU Subsidiary.

    (h) INFORMATION SUPPLIED. None of the information supplied by or on behalf
of, or to be supplied by or on behalf of, NU specifically for inclusion or
incorporation by reference in (i) the Form S-4 will, at the time the Form S-4 is
filed or becomes effective under the Securities Act, contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances in which they are made, not misleading or (ii) the Joint Proxy
Statement will, at the date it is first mailed to the NU Shareholders or at the
time of the NU Shareholders Meeting, contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary in order to make the statements therein, in light of the circumstances
under which they are made, not misleading. The Form S-4 and the Joint Proxy
Statement, insofar as they relate to NU, will comply as to form in all material
respects with the requirements of the Securities Act and the Exchange Act,
respectively, and the respective rules and regulations thereunder.

    (i) ABSENCE OF CERTAIN CHANGES OR EVENTS. Except as disclosed in the NU SEC
Documents filed pursuant to the Securities Act or the Exchange Act and publicly
available prior to the date of this Agreement (the "PREVIOUSLY FILED NU SEC
DOCUMENTS"), since December 31, 1998, to the date of this Agreement, (i) NU and
each of the NU Subsidiaries have conducted their respective businesses only in
the ordinary course of business consistent with past practice and (ii) there has
not been, and no fact or condition exists which, individually or in the
aggregate, would have a Material Adverse Effect on NU. Except as disclosed in
the Previously Filed NU SEC Documents, from December 31, 1998 through the date
of this Agreement, there has not been (i) any declaration, setting aside or
payment of any dividend or other distribution (whether in cash, stock or
property) with respect to any equity interest of NU, (ii) any split, combination
or reclassification of any equity interest of NU or any issuance or the
authorization of any issuance of any equity interest of NU or NU Voting Debt or
any other securities in respect of, in lieu of or in substitution for any equity
interest of NU, except for issuances of NU Common Shares under the NU Stock
Plans in accordance with their present terms or upon exercise of outstanding NU
Stock Options, or (iii) except as may have been required by a change in GAAP,
any change in accounting methods, principles or practices by NU or any NU
Subsidiary materially affecting their respective assets, liabilities or
business. As of the date of this Agreement, none of (i) the Agreement and Plan
of Merger (the "YANKEE MERGER AGREEMENT") dated as of June 14, 1999 among Yankee
Energy System, Inc. ("YANKEE") and NU, (ii) the Purchase and Sale Agreement (the
"CL&P/ NGC SALE AGREEMENT") dated July 2, 1999 between The Connecticut Light and
Power Company ("CL&P") and Northeast Generation Company ("NGC"), (iii) the
Purchase and Sale Agreement (the

                                       16
<PAGE>
"NRG SALE AGREEMENT") dated July 1, 1999, between CL&P and NRG, Inc. (the "NRG
SALE AGREEMENT") or (iv) the Purchase and Sale Agreement (the "WMECO/NGC SALE
AGREEMENT") dated July 2, 1999, between Western Massachusetts Electric Company
("WMECO") and NGC has been amended, modified or supplemented.

    (j) COMPLIANCE WITH APPLICABLE LAWS; LITIGATION. Except as disclosed in the
Previously Filed NU SEC Documents, NU and the NU Subsidiaries are in compliance
with the terms of the NU Permits and all Applicable Laws, except where the
failure so to comply would not have, individually or in the aggregate, a
Material Adverse Effect on NU. Except as disclosed in the Previously Filed NU
SEC Documents, no action, demand, requirement or investigation by any
Governmental Entity and no suit, action or proceeding by any person, in each
case with respect to NU or any NU Subsidiary or any of their respective
properties is pending or, to the knowledge of NU, threatened, other than, in
each case, those the outcome of which, individually or in the aggregate, would
not have a Material Adverse Effect on NU. All utility rates charged by NU and
the applicable NU Subsidiaries have been and continue to be made pursuant to
lawfully filed tariffs and contracts. This provision shall not apply to
environmental or to health and safety matters, which are exclusively the subject
of Section 3.01(t).

    (k) ABSENCE OF CHANGES IN BENEFIT PLANS. Since the date of the most recent
audited financial statements included in the Previously Filed NU SEC Documents,
there has not been any adoption or amendment in any material respect by NU or
any NU Subsidiary of any collective bargaining agreement or any material bonus,
pension, profit sharing, savings, deferred compensation, incentive compensation,
stock ownership, stock purchase, stock option, phantom stock, retirement,
vacation, severance, disability, death benefit, hospitalization, medical or
other plan, arrangement or understanding providing benefits to any current or
former trustee, director, officer or employee of NU or any NU Subsidiary
(collectively, the "NU BENEFIT PLANS"), or any material change in any actuarial
or other assumption used to calculate funding obligations with respect to any NU
pension or post-retirement benefit plans or arrangements, or any material change
in the manner in which contributions to any NU pension or post-retirement
benefit plans or arrangements are made or the basis on which such contributions
are determined.

    (l) EMPLOYEE MATTERS; ERISA. (i) Except for employment agreements providing
benefits (other than material severance benefits) but no employment term other
than at will, Section 3.01(l)(i) of the NU Disclosure Schedule contains a true
and complete list of each (A) written or material oral deferred compensation,
bonus or other incentive compensation, stock purchase, stock option, restricted
stock and other equity compensation or ownership plan, program, agreement or
arrangement; (B) written or material oral severance or termination pay, medical,
surgical, hospitalization, life insurance and other "welfare" plan, fund or
program (within the meaning of Section 3(l) of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA")); (C) profit-sharing, stock bonus or
other "pension" plan, fund or program (within the meaning of Section 3(2) of
ERISA); (D) written or material oral employment, retention, consulting,
termination or severance agreement; and (E) other written or material oral
employee benefit plan, fund, program, agreement or arrangement, in each case,
that is sponsored, maintained or contributed to or required to be contributed to
by NU or by any trade or business, whether or not incorporated (an "ERISA
AFFILIATE"), that together with NU would be deemed a "single employer" within
the meaning of Section 4001(b) of ERISA, or to which NU or an ERISA Affiliate is
party, for the benefit of any employee or former employee of NU or any NU
Subsidiary (the foregoing plans, funds, programs, agreements and arrangements in
this Section 3.01(l)(i) being referred to collectively as the "NU PLANS").

        (ii) With respect to each NU Plan (except for NU Plans that are
    "multiemployer plans" as that term is defined in Section 3(37) of ERISA), NU
    has heretofore delivered or made available to CEI true and complete copies
    of each of the following documents:

           (A) a copy of each written NU Plan and any amendments thereto;

                                       17
<PAGE>
           (B) a copy of the two most recent annual reports on Internal Revenue
       Service Form 5500 and actuarial reports, if required under ERISA, and the
       most recent report prepared with respect thereto in accordance with
       Statement of Financial Accounting Standards Nos. 87 and 106;

           (C) a copy of the most recent Summary Plan Description (including
       supplements) required under ERISA with respect thereto;

           (D) if the NU Plan is funded through a trust or any third party
       funding vehicle, a copy of the trust or other funding agreement and the
       latest financial statements thereof and all related agreements; and

           (E) the most recent determination letter or pending determination
       letter received from the Internal Revenue Service with respect to each NU
       Plan intended to qualify under Section 401 or 501(c)(9) of the Code.

        (iii) No liability under Title IV or Section 302 of ERISA has been
    incurred by NU or any ERISA Affiliate that has not been satisfied in full,
    and no condition exists that presents a risk to NU or any ERISA Affiliate of
    incurring any such liability, other than liability for premiums due the
    Pension Benefit Guaranty Corporation ("PBGC") (which premiums have been paid
    when due) in each case except where such occurrence, individually or in the
    aggregate, would not have a Material Adverse Effect on NU. No NU Plan has,
    to the knowledge of NU, engaged in a "prohibited transaction" (as defined in
    Section 4975 of the Code or Section 406 of ERISA) not exempted under or
    pursuant to Section 4975 of the Code or Section 408 of ERISA, no NU Plan
    subject to Title IV of ERISA (a "TITLE IV NU PLAN") has been terminated by
    the PBGC or has been the subject of a "reportable event" (as defined in
    Section 4043 of ERISA and the regulations thereunder) for which the 30-day
    notice requirement has not been waived and NU has not received any notice of
    intent by PBGC to terminate any such Plan in each case except where such
    occurrence, individually or in the aggregate, would not have a Material
    Adverse Effect on NU. Schedule 3.01(l)(iii) of the NU Disclosure Schedule
    sets forth, in respect of each of the last two completed plan years,
    (x) the amount of contributions made by NU and its Affiliates to each Title
    IV NU Plan and (y) the amount of insurance premiums required to be paid by
    NU and its Affiliates to the PBGC.

        (iv) With respect to each Title IV NU Plan, the present value of accrued
    benefits under such Plan, based upon the actuarial assumptions used for
    funding purposes in the most recent actuarial report prepared by such Plan's
    actuary with respect to such Plan did not exceed, as of its latest valuation
    date, the then current value of the assets of such Plan allocable to such
    accrued benefits.

        (v) No Title IV NU Plan or any trust established thereunder has incurred
    any "accumulated funding deficiency" (as defined in Section 302 of ERISA and
    Section 412 of the Code), whether or not waived, as of the last day of the
    most recent fiscal year of each Title IV NU Plan ended prior to the date of
    this Agreement nor has there been any application for waiver of the minimum
    funding standards imposed by Section 412 of the Code. All contributions
    required to be made with respect to any NU Plan on or prior to the Closing
    Date have been or will have been timely made or are reflected on the balance
    sheet except where such failure to make any such contributions, individually
    or in the aggregate, would not have a Material Adverse Effect on NU.

    (vi) No Title IV NU Plan is a "multiemployer plan", as defined in
Section 3(37) of ERISA, nor is any Title IV NU Plan a plan described in
Section 4063(a) of ERISA.

    (vii) Each NU Plan has been operated and administered in accordance with its
terms and Applicable Law, including but not limited to ERISA and the Code, the
rules and regulations thereunder, except where such noncompliance, individually
or in the aggregate, would not have a Material Adverse Effect on NU. Each NU
Plan intended to be "qualified" under Section 401(a) or

                                       18
<PAGE>
501(c)(9) of the Code is so qualified and its trusts maintained thereunder are
exempt from taxation under Section 501(a) of the Code. To the knowledge of NU,
there is no fact, condition or set of circumstances existing that could
adversely affect such favorable determination. To NU's knowledge, there are no
investigations pending in respect of any NU Plan by any Governmental Entity.

    (viii) No NU Plan provides medical, surgical, hospitalization, death or
similar benefits (whether or not insured) for employees or former employees (or
their beneficiaries) of NU or any NU Subsidiary for periods extending beyond
their respective dates of retirement or other termination of service, other than
(A) coverage mandated by Applicable Law, (B) death benefits under any "pension
plan", or (C) benefits the full cost of which is borne by the current or former
employee (or his beneficiary).

    (ix) To the knowledge of NU, no amounts payable under the NU Plans will fail
to be deductible for Federal income tax purposes by virtue of either
Section 280G or 162(m) of the Code.

        (x) The consummation of the transactions contemplated by this Agreement
    will not, either alone or in combination with another event, (A) entitle any
    current or former trustee, director, officer or employee of NU or any ERISA
    Affiliate to severance pay, unemployment compensation or any other payment,
    (B) accelerate the time of payment or vesting, or increase the amount of
    compensation due any such trustee, director, officer or employee or
    (C) require the immediate funding or financing of any compensation or
    benefits. Schedule 3.01(l)(x) of the NU Disclosure Schedule sets forth
    estimates prepared by NU of the amounts reasonably expected to be paid to
    participants in any NU Plan (or by which any of their benefits may be
    increased or accelerated) as a result of (A) the execution of this
    Agreement, (B) the obtaining of the NU Shareholders Approval,
    (C) consummation of the Mergers and (D) termination or constructive
    termination of any trustee, director, officer or employee's employment with
    NU or any NU Subsidiary. For purposes of the preceding sentence, the
    determination of the amounts set forth in Schedule 3.01(l)(x) is based upon
    each employee's current compensation, outstanding awards and benefits
    accrued (as applicable) and on such other factors as NU, taking into account
    Applicable Law, deems reasonable and appropriate.

        (xi) To the knowledge of NU, there are no pending, threatened or
    anticipated claims by or on behalf of any NU Plan, by any employee or
    beneficiary covered under any such NU Plan, or otherwise involving any such
    NU Plan (other than routine claims for benefits) except to the extent that
    such claims, individually or in the aggregate, would not have a Material
    Adverse Effect on NU.

    (m) LABOR AND EMPLOYEE RELATIONS. (i) Except as disclosed in the Previously
Filed NU SEC Documents, as of the date of this Agreement, (A) except for the
existing collective bargaining agreements with the unions set forth on
Section 3.01(m) of the NU Disclosure Schedule, in each case as in effect on the
date of this Agreement (copies of which have been delivered to CEI), neither NU
nor any of the NU Subsidiaries is a party to any collective bargaining agreement
or other labor agreement with any union or labor organization and (B) to the
knowledge of NU, there is no current union representation question involving
employees of NU or any of the NU Subsidiaries, nor does NU have knowledge of any

acquiring, holding, voting or disposing of, in each case, shares of capital
stock of CEI or other securities convertible into shares of capital stock of

    any NU Subsidiary has received any communication (written or oral)
    reasonably grounded in fact, from any person or Governmental Entity that
    alleges that NU or any of the NU Subsidiaries is not in such compliance with
    applicable Environmental Laws. Compliance with all applicable Environmental

    costs of pollution control equipment

                                       21
<PAGE>
    that are known or anticipated to be required in the future, beyond those

    Effect on NU.

        (B) ENVIRONMENTAL PERMITS. (I) NU and each of the NU Subsidiaries has
    obtained or has applied for all environmental, health and safety permits and
    governmental authorizations (collectively, the "ENVIRONMENTAL PERMITS")

    operations, except where the failure to so obtain, individually or in the
    aggregate, would not have a Material Adverse Effect on NU, (II) all such
    Environmental Permits are in good standing or, where applicable, a renewal
    application has been timely filed and is pending agency approval, except
    where the failure of such Environmental Permits to be in good standing or to
    have filed a renewal application on a timely basis would not, individually
    or in the aggregate, have a Material Adverse Effect on NU, (III) NU and, to
    the knowledge of NU, the NU Subsidiaries are in material compliance with all
    terms and conditions of the Environmental Permits, except where failure to
    so comply, individually or in the aggregate, would not have a Material
    Adverse Effect on NU and (IV) neither NU nor, to the knowledge of NU, any of
    the NU Subsidiaries has been advised by any Governmental Entity of any
    potential change in the terms and conditions of the Environmental Permits
    either prior to or upon their renewal, except for such potential changes as
    would not, individually or in the aggregate, have a Material Adverse Effect
    on NU.

        (C) ENVIRONMENTAL CLAIMS. There are no Environmental Claims (as defined
    in Section 3.01(t)(ii)) that would, individually or in the aggregate, have a
    Material Adverse Effect on NU, pending or, to the knowledge of NU,
    threatened, (1) against NU or any of the NU Subsidiaries, (2) to the
    knowledge of NU, against any person or entity whose liability for any

        (D) RELEASES. There have been no Releases (as defined in
    Section 3.01(t)(ii)) of any Hazardous Material (as defined in
    Section 3.01(t)(ii)) that would be reasonably likely to form the basis of
    any Environmental Claim against NU or, to the knowledge of NU, any of the NU
    Subsidiaries, or against any person or entity whose liability for any
    Environmental Claim NU or any of the NU Subsidiaries has or may have
    retained or assumed either contractually or by operation of law, except for
    any Environmental Claim which, individually or in the aggregate, would not
    have a Material Adverse Effect on NU.

        (E) ASSUMED AND RETAINED LIABILITIES. Neither NU nor, to the knowledge
    of NU, any of the NU Subsidiaries has retained or assumed either
    contractually or by operation of law any liabilities or obligations that
    would be reasonably likely to form the basis for any Environmental Claim,
    which would, individually or in the aggregate, have a Material Adverse
    Effect on NU.

        (F) PREDECESSORS. NU has no knowledge with respect to any predecessor of
    NU or any of the NU Subsidiaries, of any Environmental Claim that,

    SECTION 3.02.  REPRESENTATIONS AND WARRANTIES OF CEI.  Except as set forth
on the Disclosure Schedule delivered by CEI to NU prior to the execution of this

duly organized, validly existing and in good standing under the laws of the
jurisdiction in which it is organized and has the requisite corporate or other
power, as the case may be, and authority to carry on its business as now being
conducted, except, as to CEI Subsidiaries, for those jurisdictions where the
failure to be so organized, existing or in good standing would not have,
individually or in the aggregate, a Material Adverse Effect on CEI. The
respective articles of incorporation and by-laws or other organizational
documents of each CEI Subsidiary, in each case as amended through the date of
this Agreement, do not contain any provision limiting or otherwise restricting
the ability of CEI to control each such CEI Subsidiary.

"holding company", a "subsidiary company", an "affiliate" of any public-utility
company, an "exempt wholesale generator" or a "foreign utility company" within

through the date of this Agreement, CEI has not issued any shares of CEI Common
Stock or placed any shares of CEI Common Stock in its treasury (except, in each

Subsidiary having the right to vote on matters presented to shareholders of CEI
or such CEI Subsidiary (or convertible into securities of CEI or any CEI
Subsidiary having the right to vote on matters presented to shareholders of CEI
or such CEI Subsidiary) ("CEI VOTING DEBT") were outstanding. Section 3.02(c) of
the CEI Disclosure Schedule sets forth a complete and correct list, as of the
date of this Agreement, of the number of shares of CEI Common Stock subject to
employee stock options to purchase or receive CEI Common Stock and the exercise
prices thereof and a list of shares reserved for issuance relating to other
rights to purchase or receive CEI Common Stock granted under the CEI Stock Plans

nonassessable and (except for any series of preferred stock of any CEI
Subsidiary held by public shareholders) all the outstanding shares of capital
stock of, or other equity interests in, each of the CEI Subsidiaries are, as of

conversion or exchange under any outstanding security, instrument or other
agreement, obligating any such CEI Subsidiary to issue, deliver or sell, or

Agreement by CEI and the consummation by CEI of the transactions contemplated by
this Agreement have been duly authorized by all necessary action on the part of
CEI, subject to the CEI Shareholder Approval. This Agreement has been duly
executed and delivered by CEI and, assuming the due authorization, execution and
delivery by each of the other parties hereto, constitutes the legal, valid and
binding obligation of CEI, enforceable against CEI in accordance with its terms.

    STATUTORY APPROVALS").

    (e) REPORTS AND FINANCIAL STATEMENTS. The filings (other than immaterial
filings) required to be made by CEI and the CEI Subsidiaries under the
Securities Act, the Exchange Act, PUHCA, the Power Act, the Atomic Energy Act or
applicable state public utility laws and regulations have been filed with the
SEC, FERC, the NRC or the appropriate state public utilities commission, as the
case may be, including all forms, statements, reports, tariffs, contracts,
agreements (oral or written) and all documents, exhibits, amendments and
supplements appertaining thereto required to be filed with such commission. As
of their respective dates, the reports, schedules, forms, statements and other
documents (including exhibits and all other information incorporated therein)
required to be filed by CEI or any CEI Subsidiary with the SEC since January 1,
1997 (the "CEI SEC DOCUMENTS") complied in all material respects with the
requirements of the Securities Act or the Exchange Act, as the case may be, and
the rules and regulations of the SEC promulgated thereunder applicable to such
CEI SEC Documents, and none of the CEI SEC Documents when filed contained any
untrue statement of a material fact or omitted to state a material fact required
to be stated therein or necessary in order to make the statements therein, in
light of the circumstances under which they were made, not misleading. The
financial statements of CEI included in the CEI SEC Documents (the "CEI
FINANCIAL STATEMENTS") comply as to form, as of their respective dates of filing
with the SEC, in all material respects with applicable accounting requirements
and the published rules and regulations of the SEC with respect thereto, have
been prepared in accordance with GAAP (except, in the case of unaudited
statements, as permitted by Form 10-Q of the SEC) applied on a consistent basis
during the periods involved (except as may be indicated in the notes thereto)
and fairly present in all material respects the consolidated financial position
of CEI and its consolidated subsidiaries as of the dates thereof and the
consolidated

                                       26
<PAGE>
results of their operations and cash flows for the periods then ended (subject,
in the case of unaudited statements, to normal recurring year-end audit
adjustments).

    (f) ASSETS AND PROPERTIES. CEI and the CEI Subsidiaries have good and
sufficient title to all properties and assets reflected on the consolidated
balance sheet of CEI and its consolidated subsidiaries included in the CEI
Financial Statements or thereafter acquired (except as sold or otherwise
disposed of since the date of such balance sheet) in each case free and clear of
all Liens, except where the failure to have good title free and clear of all
Liens to any such properties or assets would not have, individually or in the
aggregate, a Material Adverse Effect on CEI. The tangible assets of CEI and the
CEI Subsidiaries are in an adequate state of maintenance and repair (except for
ordinary wear and tear), except where their failure to be in such state of
maintenance and repair would not have, individually or in the aggregate, a
Material Adverse Effect on CEI.

    (g) FRANCHISES. CEI and the CEI Subsidiaries own or have sufficient rights
and consents to locate and use under existing franchises, permits, easements,
leases, and license agreements (the "CEI PERMITS") all properties, rights and
assets necessary for the conduct of their business and operations as currently
conducted, except where the failure to own or have sufficient rights to such
properties, rights and assets would not have, individually or in the aggregate,
a Material Adverse Effect on CEI. To the knowledge of CEI, no other private
corporation has of the date of this Agreement commenced or, without obtaining a
certificate of public convenience and necessity from the applicable state
utility commission, can commence operations distributing electricity to the
general public along and across public streets and ways in any part of the
territories now served by CEI or any CEI Subsidiary.

    (h) INFORMATION SUPPLIED. None of the information supplied by or on behalf
of, or to be supplied by or on behalf of, CEI specifically for inclusion or
incorporation by reference in (i) the Form S-4 will, at the time the Form S-4 is
filed or becomes effective under the Securities Act, contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances in which they are made, not misleading or (ii) the Joint Proxy
Statement will, at the date it is first mailed to the CEI Shareholders or at the
time of the CEI Shareholders Meeting, contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary in order to make the statements therein, in light of the circumstances
under which they are made, not misleading. The Form S-4 and the Joint Proxy
Statement insofar as they relate to CEI will comply as to form in all material
respects with the requirements of the Securities Act and the Exchange Act,
respectively, and the respective rules and regulations thereunder.

    (i) ABSENCE OF CERTAIN CHANGES OR EVENTS. Except as disclosed in the CEI SEC
Documents filed pursuant to the Securities Act or the Exchange Act and publicly
available prior to the date of this Agreement (the "PREVIOUSLY FILED CEI SEC
DOCUMENTS"), since December 31, 1998, to the date of this Agreement, (i) CEI and
each of the CEI Subsidiaries have conducted their respective businesses only in
the ordinary course of business consistent with past practice and (ii) there has
not been, and no fact or condition exists which, individually or in the
aggregate, would have a Material Adverse Effect on CEI. Except as disclosed in
the Previously Filed CEI SEC Documents, from December 31, 1998 through the date
of this Agreement, there has not been (i) any declaration, setting aside or
payment of any dividend or other distribution (whether in cash, stock or
property) with respect to any capital stock of CEI (other than regular quarterly
cash dividends), (ii) any split, combination or reclassification of any capital
stock of CEI or any issuance or the authorization of any issuance of any capital

shares of CEI Common Stock under the CEI Stock Plans in accordance with their
present terms or upon exercise of outstanding CEI Stock Options, or
(iii) except as may have been required by a change in GAAP, any change in
accounting methods, principles or practices by CEI or any CEI Subsidiary
materially affecting their respective assets, liabilities or business.

Previously Filed CEI SEC Documents, CEI and the CEI Subsidiaries are in
compliance with the terms of the CEI Permits and all Applicable Laws, except
where the failure so to comply would not have, individually or in the aggregate,
a Material Adverse Effect on CEI. Except as disclosed in the Previously Filed
CEI SEC Documents, no action, demand, requirement or investigation by any
Governmental Entity and no suit, action or proceeding by any person, in each
case with respect to CEI or any CEI Subsidiary or any of their respective
properties is pending or, to the knowledge of CEI, threatened, other than, in
each case, those the outcome of which, individually or in the aggregate, would
not have a Material Adverse Effect on CEI. All utility rates charged by CEI and
the applicable CEI Subsidiaries have been and continue to be made pursuant to

environmental or to health and safety matters, which are exclusively the subject
of Section 3.02(r).

employee of CEI or any CEI Subsidiary (collectively, the "CEI BENEFIT PLANS")
has been administered in accordance with its terms, except for any failures so
to administer that, individually or in the aggregate, would not have a Material
Adverse Effect on CEI. CEI, the CEI Subsidiaries and all the CEI Benefit Plans
are in compliance with the applicable provisions of ERISA, the Code and all
other applicable laws and the terms of all applicable collective bargaining
agreements, except for any failures to be in such compliance that, individually
or in the aggregate, would not have a Material Adverse Effect on CEI.

    (l) TAXES. (i) Except as to any items that would not, individually or in the
aggregate, have a Material Adverse Effect on CEI:

       state, local and foreign income and other Tax returns or reports
       (including declarations of estimated tax) required to be filed by it, and
       all such returns are complete and accurate, (II) paid all Taxes of any
       nature whatsoever (together with any related penalties and interest) that
       are shown on such Tax returns as due and payable on or before the date of
       this Agreement, and (III) paid on behalf of itself or others all Taxes
       otherwise required to be paid on or before the date of this Agreement.

           (B) There are no claims or assessments pending against CEI or any of
       the CEI Subsidiaries for any alleged deficiency in Tax, and, to the
       knowledge of CEI, there is not any threatened Tax claims or assessments

           (C) CEI and each of the CEI Subsidiaries has established adequate
       reserves for current Taxes and for any liability for deferred Taxes in

       with respect to CEI and each of the CEI Subsidiaries have been timely
       withheld, collected or deposited, as the case may be, and, to the extent
       required, have been paid to the relevant taxing authority.

           (E) There are no Liens for Taxes (other than for current Taxes not
       yet due and payable) on the assets of the CEI or any CEI Subsidiary.

           (F) The Federal income Tax returns of the consolidated group for
       which CEI is the common parent either have been examined and settled with
       the Internal Revenue Service or closed by virtue of the expiration of the
       applicable statute of limitations for all years through 1991.

                                       28
<PAGE>
           (G) None of CEI or any CEI Subsidiary shall be required to include in
       a taxable period ending after the Effective Time an amount of taxable
       income attributable to income that accrued in a prior taxable period but
       was not recognized in any prior taxable period as a result of the
       installment method of accounting, the completed contract method of
       accounting, the long-term contract method of accounting, the cash method
       of accounting or Section 481 of the Code or comparable provisions of
       state, local or foreign Tax law.

           (H) Neither CEI nor any CEI Subsidiary has, within the five preceding
       taxable years, deferred gain recognition for Federal income tax purposes

       disclosure on a Tax return pursuant to Section 6662(d)(2)(B)(ii) of the
       Code.

           (K) Neither CEI nor any CEI Subsidiary has constituted either a
       "distributing corporation" or a "controlled corporation" (within the
       meaning of Section 355(a)(1)(A) of the Code) in a distribution of stock
       qualifying for tax-free treatment under Section 355 of the Code (I) in
       the two years prior to the date of this Agreement or (II) in a
       distribution which could otherwise constitute part of a "plan" or "series
       of related transactions" (within the meaning of Section 355(e) of the
       Code) in conjunction with the Mergers.

        (ii) Neither CEI nor any CEI Subsidiary has taken any action, or failed
    to take any action, or has knowledge of any fact, agreement, plan or other
    circumstance that is reasonably likely to prevent (A) the Mergers from
    constituting a transaction described in Section 351 of the Code or (B) the
    CEI Merger from constituting a transaction described in Section 368(a) of
    the Code.

    (m) VOTING REQUIREMENTS. The affirmative vote of a majority of the shares of
CEI Common Stock (excluding any shares of CEI Common Stock held by CECONY)

the only vote of the holders of any class or series of capital stock of CEI or
any CEI Subsidiary necessary to approve and adopt this Agreement and the
transactions contemplated hereby.

    (n) STATE ANTI-TAKEOVER STATUTES. Assuming the accuracy of the
representation of NU set forth in Section 3.01(s), Section 912 of the NYBCL is
not applicable to the transactions contemplated by this Agreement. To the
knowledge of CEI, no other anti-takeover or similar statute or regulation
applies or purports to apply to the transactions contemplated by this Agreement.

    (o) BROKERS. No broker, investment banker, financial advisor or other
person, other than Salomon Smith Barney, the fees and expenses of which will be
paid by CEI, is entitled to any broker's, finder's, financial advisor's or other
similar fee or commission in connection with the transactions contemplated by
this Agreement based upon arrangements made by or on behalf of CEI.

    (p) OPINION OF FINANCIAL ADVISOR. CEI has received the opinion of Salomon
Smith Barney, dated as of October 12, 1999, to the effect that, as of such date,
the Merger Consideration is fair from a financial point of view to the CEI
Shareholders.

                                       29
<PAGE>

equity interest of NU or other securities convertible into shares of equity
interest of NU, except for such shares as may be held by trustees of pension,
employee benefit, nuclear decommissioning, spent fuel or similar trusts, the
investment management of which is carried out by non-affiliates under contract
with affiliates of CEI.

    (r) ENVIRONMENTAL PROTECTION. Except as set forth in the Previously Filed
CEI SEC Documents:

        (i) COMPLIANCE. CEI and, to the knowledge of CEI, each of the CEI
    Subsidiaries are, and have been, in compliance with all applicable
    Environmental Laws, except where the failure to so comply, individually or
    in the aggregate, would not have a Material Adverse Effect on CEI, and
    neither CEI nor any CEI Subsidiary has received any communication (written
    or oral) reasonably grounded in fact, from any person or Governmental Entity
    that alleges that CEI or any of the CEI Subsidiaries is not in such
    compliance with applicable Environmental Laws. Compliance with all
    applicable Environmental Laws will not require CEI or, to the knowledge of
    CEI, any CEI Subsidiary to incur costs, including the costs of pollution
    control equipment that are known or anticipated to be required in the
    future, beyond those currently budgeted for the three CEI fiscal years
    beginning with January 1, 1999, that, individually or in the aggregate,
    would have a Material Adverse Effect on CEI.

        (ii) ENVIRONMENTAL PERMITS. (A) CEI and each of the CEI Subsidiaries has
    obtained or has applied for all Environmental Permits necessary for the
    construction of their facilities or the conduct of their operations, except
    where the failure to so obtain, individually or in the aggregate, would not
    have a Material Adverse Effect on CEI, (B) all such Environmental Permits
    are in good standing or, where applicable, a renewal application has been
    timely filed and is pending agency approval, except where the failure of
    such Environmental Permits to be in good standing or to have filed a renewal
    application on a timely basis would not, individually or in the aggregate,
    have a Material Adverse Effect on CEI, (C) CEI and, to the knowledge of CEI,
    the CEI Subsidiaries are in material compliance with all terms and
    conditions of the Environmental Permits, except where failure to so comply,
    individually or in the aggregate, would not have a Material Adverse Effect
    on CEI and (D) neither CEI nor, to the knowledge of CEI, any of the CEI
    Subsidiaries has been advised by any Governmental Entity of any potential
    change in the terms and conditions of the Environmental Permits either prior
    to or upon their renewal, except for such potential changes as would not,
    individually or in the aggregate, have a Material Adverse Effect on CEI.

        (iii) ENVIRONMENTAL CLAIMS. There are no Environmental Claims that
    would, individually or in the aggregate, have a Material Adverse Effect on
    CEI, pending or, to the knowledge of CEI, threatened, (A) against CEI or any
    of the CEI Subsidiaries, (B) to the knowledge of the CEI, against any person
    or entity whose liability for any Environmental Claim CEI or any of the CEI
    Subsidiaries has or may have retained or assumed either contractually or by
    operation of law, or (C) against any currently owned, leased or managed, in
    whole or in part, real or personal property or operations of CEI or any of
    the CEI Subsidiaries or, to the knowledge of the CEI, against any formerly
    owned, leased or managed, in whole or in part, real or personal property or
    operations of CEI or any of the CEI Subsidiaries.

        (iv) RELEASES. There have been no Releases of any Hazardous Material
    that would be reasonably likely to form the basis of any Environmental Claim
    against CEI or, to the knowledge of CEI, any of the CEI Subsidiaries, or
    against any person or entity whose liability for any Environmental Claim CEI
    or any of the CEI Subsidiaries has or may have retained or assumed either
    contractually or by operation of law, except for any Environmental Claim
    which, individually or in the aggregate, would not have a Material Adverse
    Effect on CEI.

                                       30
<PAGE>
        (v) ASSUMED AND RETAINED LIABILITIES. Neither CEI nor, to the knowledge
    of CEI, any of the CEI Subsidiaries has retained or assumed either
    contractually or by operation of law any liabilities or obligations that
    would be reasonably likely to form the basis for any Environmental Claim,
    which would, individually or in the aggregate, have a Material Adverse
    Effect on CEI.

        (vi) PREDECESSORS. CEI has no knowledge, with respect to any predecessor
    of CEI or any of the CEI Subsidiaries, of any Environmental Claim that,
    individually or in the aggregate, would have a Material Adverse Effect on
    CEI.

    (s) REGULATION AS A UTILITY. Section 3.02(s) of the CEI Disclosure Schedule
lists each CEI Subsidiary that, as of the date of this Agreement, is regulated
as a public utility and each jurisdiction imposing such regulation. Neither CEI
nor any "subsidiary company" or "affiliate" of CEI is, as of the date of this
Agreement, subject to regulation as a public utility or public service company
(or similar designation) by any other state in the United States or any foreign
country.

    (t) OPERATIONS OF NUCLEAR POWER PLANTS. The operations of the nuclear
generation stations (collectively, the "CEI NUCLEAR FACILITIES") currently or
formerly owned by CEI or any of its affiliates are and have been conducted in
compliance with all Applicable Laws, including Environmental Laws, except for
such failures to comply as would not have, individually or in the aggregate, a
Material Adverse Effect on CEI. Each of the CEI Nuclear Facilities maintains,
and is in material compliance with, emergency plans designed to respond to an
unplanned Release therefrom of radioactive materials and the NRC has determined
that such plans are in material compliance with its requirements. As of the date
of this Agreement, the plans for the current or future decommissioning of each
of the CEI Nuclear Facilities and for the storage of spent nuclear fuel conform
with the requirements of Applicable Law and are funded consistent with
Applicable Law.

    (u) INSURANCE. CEI and each of the CEI Subsidiaries is, and has been
continuously since January 1, 1997, insured with financially responsible
insurers in such amounts and against such risks and losses as are customary in
all material respects for companies conducting business as conducted by CEI and
the CEI Subsidiaries during such time period. Neither CEI nor any CEI
Subsidiaries has received any notice of cancelation or termination with respect
to any material insurance policy of CEI or any CEI Subsidiaries, except to the
extent any such cancelation or termination that would not have, individually or
in the aggregate, a Material Adverse Effect on CEI.

    (v) FINANCING. CEI will have, or cause the Company to have, available, at or
prior to the Effective Time, sufficient cash in immediately available funds to
pay the Cash Consideration and to consummate the NU Merger and the other
transactions contemplated hereby.

                                   ARTICLE IV
                            CERTAIN COVENANTS OF NU

ordinary course consistent with past practice and in compliance in all material
respects with all Applicable Laws and use all reasonable best efforts to
preserve intact their respective current business organizations, preserve the
goodwill and relationships with Governmental Entities, customers, suppliers and
others having business dealings with them and, subject to prudent management of
workforce needs and ongoing programs currently in force, keep available the
services of their respective present officers and employees. Without limiting
the generality of the foregoing, except as set forth in Section 4.01 of the NU
Disclosure Schedule (and making reference, as

                                       31
<PAGE>
appropriate, to the particular subsection of this Section 4.01 to which

    prior to the date on which the Effective Time occurs, which does not exceed
    an amount equal to the product of (I) a fraction the (x) numerator of which
    is equal to the number of days between the last payment date of a regular
    quarterly dividend and the record date of such special dividend (excluding
    such last payment date but including the record date of such special
    dividend) and (y) the denominator of which is equal to the number of days
    between the last payment date of a regular quarterly dividend and the same
    calendar day in the third month after the month in which such last payment
    date occurred (excluding such last payment date but including such same
    calendar day), multiplied by (II) (x) if the record date for such special
    dividend is on or prior December 31, 2000, $.10 per share or (y) if the

    Section 4.01(k)) or pursuant to the terms of any restructuring legislation
    or order of the SEC, DPUC, NHPUC or MDTE applicable to such NU Subsidiary,
    PROVIDED that such purchase, redemption or other acquisition is funded
    solely out of the proceeds of one or more asset sales (to the extent
    permitted by Section 4.01(e)) or NU Securitizations (as defined in
    Section 4.01(e)) by such NU Subsidiary and on terms reasonably acceptable to
    CEI, (B) any NU Common Shares repurchased solely for purpose of delivering
    such NU Common Shares to the holders of the common stock, par value $5.00

    date of this Agreement and (C) repurchases by any wholly owned NU Subsidiary

    business consistent with past practice (so long as such additional amount of
    NU Common Shares subject to NU Stock Options or issued

                                       32

    aggregate, unless CEI shall consent in writing to any greater number, such
    consent not to be unreasonably withheld), (ii) the issuance by any wholly

    SECTION 4.02.  NO SOLICITATION.  (a) NU shall not, nor shall it permit any
of the NU Subsidiaries to, nor shall it authorize, permit or direct any of its
trustees, directors, officers or employees or any investment banker, financial
advisor, attorney, accountant or other representative of NU or any of the NU
Subsidiaries to, directly or indirectly through another person, (i) solicit,
initiate or encourage (including by way of furnishing information), or take any
other action designed to facilitate, any inquiries or the making of any proposal
which constitutes or which may be reasonably expected to lead to any NU Takeover
Proposal (as defined below) or (ii) participate in any discussions or
negotiations regarding any NU Takeover Proposal; PROVIDED, HOWEVER, that, at any
time prior to the receipt of the NU Shareholder Approval (the "NU Applicable
Period"), NU may, (A) in response to a NU Takeover Proposal (1) that was not
solicited by it or which did not otherwise result from a breach of this
Section 4.02(a) and (2) with respect to which the Board of Trustees of NU
determines in its good faith judgment after consultation with its outside
counsel and financial advisors, (x) that there is a reasonable possibility that
such NU Takeover Proposal may constitute a NU Superior Proposal (as defined in
Section 4.02(b)) and (y) that failing to take such action could reasonably be
expected to be a breach of its fiduciary duties to the NU Shareholders, and
subject to providing prior written notice of its decision to take such action to
CEI (the "NU NEGOTIATION NOTICE") and compliance with Section 4.02(c), for a
period of twenty business days following delivery of the NU Negotiation Notice
(the "NU NEGOTIATION PERIOD"), request that the person making such NU Takeover
Proposal provide information with regard to itself and such NU Takeover Proposal
for purposes of permitting the Board of Trustees of NU to determine whether such
NU Takeover Proposal constitutes a NU Superior Proposal and (B) to the extent
that, at any time prior to expiration of the NU Negotiation Period, the Board of
Trustees of NU shall determine that such NU Takeover Proposal constitutes a NU
Superior Proposal and subject to providing prior written notice of its decision
to take such action to CEI and compliance with Section 4.02(c), during the NU
Negotiation Period (x) furnish information with respect to NU and the NU
Subsidiaries to any person making a NU Superior Proposal pursuant to a customary
confidentiality agreement containing terms no less favorable to NU than those
set forth in the Confidentiality Agreement (the "CONFIDENTIALITY AGREEMENT")
dated July 29, 1999 between CEI and NU (provided that such confidentiality
agreement shall not in any way restrict NU from complying with its disclosure
obligations under this Agreement, including with respect to such NU Superior
Proposal) and (y) participate in discussions or negotiations regarding such NU
Superior Proposal. NU shall be permitted to deliver only one NU Negotiation
Notice with respect to each person making a NU Superior Proposal, which notice
shall not be revised or supplemented. NU shall immediately cease and terminate
any existing solicitation, initiation, encouragement, activity, discussion or
negotiation with any persons conducted heretofore by it or its representatives.
For purposes of this Agreement, "NU TAKEOVER PROPOSAL" means any inquiry,
proposal or offer from any person relating to any direct or indirect acquisition
or purchase of a business (a "NU MATERIAL BUSINESS") that constitutes 15% or
more of the net revenues, net income or the assets (including equity securities)
of NU and the NU Subsidiaries, taken as a whole, or 15% or more of any class of
equity securities of NU or any NU Subsidiary owning, controlling or operating a
NU Material Business, any tender offer or exchange offer that if consummated
would result in any person beneficially owning 15% or more of any class of
equity securities of NU or any such NU Subsidiary, or any merger, consolidation,
business combination, recapitalization, liquidation, dissolution or similar
transaction involving NU or any such NU Subsidiary, other than the transactions
contemplated by this Agreement; PROVIDED, HOWEVER, that no transaction permitted
pursuant to Section 4.01(e) shall be deemed a NU Takeover Proposal for any
purpose.

    (b) Except as expressly permitted by this Section 4.02, (i) neither the
Board of Trustees of NU nor any committee thereof shall (A) withdraw or modify
in a manner adverse to CEI, or propose publicly to withdraw or modify in a
manner adverse to CEI, the approval or recommendation by such Board of Trustees
or such committee of this Agreement or the NU Merger, (B) approve or recommend,
or propose publicly to approve or recommend, any NU Takeover Proposal, or
(C) cause or permit NU to enter into any letter of intent, agreement in
principle, acquisition agreement or other similar agreement

<PAGE>
(each, a "NU ACQUISITION AGREEMENT") related to any NU Takeover Proposal and
(ii) NU shall not enter into any NU Acquisition Agreement with respect to any NU
Takeover Proposal; PROVIDED, HOWEVER, that in order to comply with its fiduciary
duties to the NU Shareholders the Board of Trustees of NU may terminate this
Agreement in accordance with the following sentence and, following such
termination and payment of the Termination Fee (as defined in Section 5.09(b)),
withdraw or modify its approval or recommendation of this Agreement and the NU
Merger. In the event that during the NU Applicable Period the Board of Trustees
of NU determines in good faith (x) that a NU Takeover Proposal constitutes a NU
Superior Proposal and (y) after consultation with its outside legal counsel,
that the failure to terminate this Agreement and accept such NU Superior
Proposal could reasonably be expected to be a breach of its fiduciary duties to
the NU Shareholders, the Board of Trustees of NU may terminate this Agreement,
but only at a time that is during the NU Applicable Period and is after the
fifth business day following CEI's receipt of written notice advising CEI that
the Board of Trustees of NU is prepared to accept a NU Superior Proposal,
specifying the material terms and conditions of such NU Superior Proposal and
identifying the person making such NU Superior Proposal; PROVIDED that,
concurrently with such termination, the Board of Trustees of NU shall cause NU
to enter into a NU Acquisition Agreement with respect to such NU Superior
Proposal and shall cause NU to pay to CEI the Termination Fee and the fees and
expenses incurred by CEI in connection with the transactions contemplated by
this Agreement pursuant to Section 5.09(b) and 5.09(c), respectively. For
purposes of this Agreement, a "NU SUPERIOR PROPOSAL" means any bona fide
proposal made by a third party to acquire, directly or indirectly, including
pursuant to a tender offer, exchange offer, merger, consolidation, business
combination, recapitalization, liquidation, dissolution or similar transaction,
for consideration consisting of cash and/or securities, more than 50% of the
combined voting power of the NU Common Shares then outstanding or all or
substantially all the assets of NU which the Board of Trustees of NU determines
in its good faith judgment (based, in the case of any determination made by the
NU Board of Trustees for purposes of this Section 4.02(b), on the written
opinion, with only customary qualifications, of an independent financial advisor
of nationally recognized reputation that the value of the consideration provided
for in such proposal exceeds the value of the consideration provided for in the
NU Merger) to be (x) reasonably capable of being completed, taking into account
all legal, financial (including the ability to obtain financing), regulatory and
other aspects of the proposal and the third party making such proposal, and
(y) more favorable to the NU Shareholders from a financial point of view than
the NU Merger and the other transactions contemplated by this Agreement (taking
into account any changes to the terms of this Agreement proposed by CEI in
response to such proposal or otherwise).

    (c) In addition to the obligations of NU set forth in paragraphs (a) and
(b) of this Section 4.02, NU shall immediately advise CEI orally and in writing
of any request for information or of any NU Takeover Proposal, the material
terms and conditions of such request or NU Takeover Proposal and the identity of
the person making such request or NU Takeover Proposal. NU shall keep CEI
reasonably informed of the status and details (including amendments or proposed
amendments) of any such request or NU Takeover Proposal.

    (d) Nothing contained in this Section 4.02 shall prohibit NU from taking and
disclosing to the NU Shareholders a position contemplated by Rule 14e-2(a)
promulgated under the Exchange Act or from making any disclosure to the NU
Shareholders if, in the good faith judgment of the Board of Trustees of NU,
after consultation with outside counsel, failure so to disclose would be
inconsistent with its obligations under Applicable Law.

                             ADDITIONAL AGREEMENTS

    SECTION 5.01.  PREPARATION OF THE FORM S-4 AND THE JOINT PROXY STATEMENT;
SHAREHOLDERS MEETINGS. (a) As soon as practicable following the date of this
Agreement, CEI and NU shall prepare and file with the SEC the Joint Proxy
Statement and CEI, NU and the Company shall prepare and file with the SEC the
Form S-4, in which the Joint Proxy Statement will be included as a prospectus.
Each of CEI, NU and the Company shall use its reasonable best efforts to have
the Form S-4 declared effective under the Securities Act as promptly as
practicable after such filing. NU will use all reasonable best efforts to cause
the Joint Proxy Statement to be mailed to the NU Shareholders, and CEI will use
all reasonable best efforts to cause the Joint Proxy Statement to be mailed to
the CEI Shareholders, in each case as promptly as practicable after the
Form S-4 is declared effective under the Securities Act. Each party hereto shall
also take any action (other than qualifying to do business in any jurisdiction
in which such party is not already so qualified) required to be taken under any
applicable state or provincial securities laws in connection with the issuance
of Company Common Stock in the Mergers and each party shall furnish all
information concerning itself and its shareholders as may be reasonably
requested in connection with any such action. No filing of, or amendment or
supplement to, the Form S-4 or the Joint Proxy Statement will be made without
the approval of all parties hereto. Each party will advise the other parties,
promptly after it receives notice thereof, of the time when the Form S-4 has
become effective or any supplement or amendment has been filed, the issuance of
any stop order, the suspension of the qualification of the Company Common Stock
issuable in connection with the Mergers for offering or sale in any
jurisdiction, or any request by the SEC for amendment of the Joint Proxy
Statement or the Form S-4 or comments thereon and responses thereto or requests
by the SEC for additional information. If at any time prior to the Effective
Time any information relating to NU or CEI, or any of their respective
affiliates, trustees, directors or officers, is discovered that should be set
forth in an amendment or supplement to any of the Form S-4 or the Joint Proxy
Statement, so that any of such documents would not include any misstatement of a
material fact or omit to state any material fact necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading, the party that discovers such information shall promptly notify
the other parties hereto and an appropriate amendment or supplement describing
such information shall be promptly filed with the SEC and, to the extent
required by Applicable Law, disseminated to the NU Shareholders and the CEI
Shareholders.

    (b) NU shall, as soon as practicable following the date of this Agreement,
duly call, give notice of, convene and hold a meeting of the NU Shareholders
(the "NU SHAREHOLDERS MEETING"), for the purpose of obtaining the NU Shareholder
Approval and shall, through its Board of Trustees, subject to the right of the
Board of Trustees to terminate this Agreement in accordance with
Section 4.02(b) in order to comply with its fiduciary duties to the NU
Shareholders, recommend to the NU Shareholders the approval and adoption of the
Trust Agreement Amendments, this Agreement, the NU Merger and the other
transactions contemplated hereby. Without limiting the generality of the
foregoing but subject to its rights to terminate this Agreement pursuant to
Section 4.02(b), NU agrees that its obligations pursuant to the first sentence
of this Section 5.01(b) shall not be affected by the commencement, public
proposal, public disclosure or direct or indirect communication to NU of any NU
Takeover Proposal.

    (c) CEI shall, as soon as practicable following the date of this Agreement,
duly call, give notice of, convene and hold a meeting of the CEI Shareholders
(the "CEI SHAREHOLDERS MEETING"), for the purpose of obtaining the CEI
Shareholder Approval and shall, through its Board of Directors, recommend to the
CEI Shareholders the approval and adoption of this Agreement, the CEI Merger and
the other transactions contemplated hereby.

                                       38
<PAGE>
    (d) CEI and NU will use reasonable best efforts to hold the CEI Shareholders
Meeting and the NU Shareholders Meeting on the same date and as soon as
practicable after the date of this Agreement.

    SECTION 5.02.  LETTERS OF NU'S ACCOUNTANTS.  NU shall use its reasonable
best efforts to cause to be delivered to CEI two letters from NU's independent
accountants, one dated a date within two business days before the date on which
the Form S-4 shall become effective and one dated a date within two business
days before the Closing Date, each addressed to CEI, in form and substance
reasonably satisfactory to CEI and customary in scope and substance for comfort
letters delivered by independent public accountants in connection with
registration statements similar to the Form S-4.

    SECTION 5.03.  LETTERS OF CEI'S ACCOUNTANTS.  CEI shall use its reasonable
best efforts to cause to be delivered to NU two letters from CEI's independent
accountants, one dated a date within two business days before the date on which
the Form S-4 shall become effective and one dated a date within two business
days before the Closing Date, each addressed to NU, in form and substance
reasonably satisfactory to NU and customary in scope and substance for comfort
letters delivered by independent public accountants in connection with
registration statements similar to the Form S-4.

    SECTION 5.04.  ACCESS TO INFORMATION; CONFIDENTIALITY; ADVICE OF
CHANGES.  (a) NU shall, and shall cause each NU Subsidiary to, afford to CEI and
to its officers, employees, accountants, counsel, financial advisors and other
representatives, reasonable access during normal business hours during the
period prior to the Effective Time (to the extent that NU or any NU Subsidiary
is not prohibited under Applicable Law or any confidentiality agreement entered
into prior to the date of this Agreement from providing access and to the extent
that such access would not constitute a waiver of the attorney client privilege
(unless such privilege has previously been waived)) to all its properties,
books, contracts, commitments, personnel and records and, during such period,
each of CEI and NU shall, and shall cause its subsidiaries to, (i) confer on a
reasonably regular and frequent basis with one or more representatives of the
other party to discuss material operational and regulatory matters and the
general status of its ongoing operations, including the investigation of
environmental, health and safety issues and, in the case of NU, with respect to
the NH Settlement Agreement and the sale of the NU Nuclear Facilities,
(ii) reasonably promptly notify the other party of its results of operations and
(iii) furnish reasonably promptly to the other party upon request any
information concerning its business, properties and personnel, in each case as
the other party may reasonably request. NU shall consult with CEI prior to
proposing or making any material amendment or modification to the NH Settlement
Agreement and with respect to all material matters relating to the sale of the
NU Nuclear Facilities, including consulting with CEI prior to filing any
divestiture or restructuring plan relating to such sale with any Applicable PUC
or Federal Governmental Entity. Each of NU and CEI shall, and shall cause its
subsidiaries to, furnish to the other reasonably promptly upon request a copy of
each report, schedule and other document filed or received by any of them
pursuant to the requirements of FERC, the SEC, Department of Justice, the
Federal Trade Commission, the NRC, any Applicable PUC, or any other Federal,
state or local regulatory agency or commission relating to the Mergers or the
other transactions contemplated hereby. Subject to obtaining customary
indemnities, each of NU and CEI shall promptly furnish to the other such
information as may be reasonably requested, including audited financial
statements and other financial information, and take such other action as may be
reasonably necessary and otherwise fully cooperate with each other in the
preparation of any registration statement under the Securities Act and other
documents necessary in connection with the issuance of securities or financings
(subject to Section 4.01 in the case of NU or any NU Subsidiary), including in
respect of the Mergers. Each party shall, and shall cause its subsidiaries and
representatives to, hold in strict confidence all documents and information
concerning the other furnished to it in connection with the transactions
contemplated by this Agreement in accordance with the Confidentiality Agreement.
No review pursuant to this Section 5.04 shall have an effect for the

                                       39
<PAGE>
purpose of determining the accuracy of any representation or warranty given by
any of the parties hereto to any of the other parties hereto.

    (b) NU and CEI shall promptly advise the other party orally and in writing
to the extent it has knowledge of (i) any representation or warranty made by it
contained in this Agreement that is qualified as to materiality becoming untrue
or inaccurate in any respect or any such representation or warranty that is not
so qualified becoming untrue or inaccurate in any material respect, (ii) the
failure by it to comply in any material respect with or satisfy in any material
respect any covenant, condition or agreement to be complied with or satisfied by
it under this Agreement and (iii) any change or event, individually or in the
aggregate, having, or which would have, a Material Adverse Effect on such party

make one or more filings with any Governmental Entity in connection with the

CEI Statutory Approvals and the NU Statutory Approvals, each of CEI and NU agree

opportunity to review and comment upon each such filing prior to making any such
filing and to coordinate the submission of such filings to the relevant
Governmental Entity. In addition, CEI shall have the right to review and approve
in advance all characterizations of the information relating to CEI, on the one
hand, and NU shall have the right to review and approve in advance all
characterizations of the information relating to NU, on the other hand, in
either case, which appear in any filing made in connection with the Mergers or
the other transactions contemplated by this Agreement. CEI and NU agree that
they will consult with each other with respect to (x) the obtaining of all such

necessary to ensure that no state anti-takeover statute or similar statute or
regulation, the effect of which would be to impede the Mergers, is or becomes
applicable to the Mergers, this Agreement or any of the other transactions
contemplated by this Agreement and (ii) if any state anti-takeover statute or
similar statute or regulation, the effect of which would be to impede the
Mergers, is or becomes applicable to the Mergers, this Agreement or any other
transaction contemplated by this Agreement, take all action necessary to ensure
that the Mergers and the other transactions contemplated by this Agreement may
be consummated as promptly

                                       40

as practicable on the terms contemplated by this Agreement and otherwise to
minimize the effect of such statute or regulation on the Mergers and the other
transactions contemplated by this Agreement.

    (d) SALE AND OPERATION OF NU NUCLEAR FACILITIES. NU shall, and shall cause
the relevant NU Subsidiaries, to use reasonable best efforts to sell and
transfer, as promptly as practicable after the date of this Agreement, their

the NU Subsidiaries shall, operate the NU Nuclear Facilities in material
compliance with Applicable Law and good industry practice.

    Stock Option divided by (B) the aggregate number of shares of Company Common

obligations of the employer under any contracts, agreements, collective
bargaining agreements and commitments of CEI and NU and their respective
subsidiaries entered into prior to the date of this Agreement (or as established
or amended in accordance with or permitted by this Agreement), which apply to
any current or former employee, or current or former trustee, director or
officer of any of the parties hereto or any of their subsidiaries; PROVIDED,
HOWEVER, that this undertaking is not intended to prevent the Company (or any
subsidiary of the Company after the Effective Time succeeding to such
obligations by operation of law) from enforcing such contracts, agreements,
collective bargaining agreements and commitments in accordance with their terms,
including any reserved right to amend, modify, suspend, revoke or terminate any
such contract, agreement, collective bargaining agreement or commitment or
portion thereof.

applicable collective bargaining agreements, for a period of three years
following the Effective Time, (i) any reductions in the employee workforce of
the then ongoing operations of the Company and its subsidiaries shall be made on
a fair and equitable basis (as determined by the Company and its subsidiaries),
in light of the circumstances and the objectives to be achieved, giving
consideration to previous work history, job experience and qualifications,
without regard to whether employment prior to the Effective Time was with CEI
and the CEI Subsidiaries or NU and the NU Subsidiaries, and any employees whose

                                       42
<PAGE>
employment is terminated or jobs are eliminated by the Company or any of its
subsidiaries during such period shall be entitled to participate on a fair and
equitable basis (as determined by the Company and its subsidiaries) in the job
opportunity and employment placement programs offered by the Company or any of
its subsidiaries for which they are eligible and (ii) employees shall be
entitled to participate in all job training, career development and educational
programs of the Company and its subsidiaries for which they are eligible, and

applicable collective bargaining agreements, the Company and its subsidiaries
shall give credit under each of their respective employee benefit plans,
programs and arrangements to employees for all service prior to the Effective
Time with CEI or NU or their respective subsidiaries, as applicable, or any
predecessor employer (to the extent that such credit was given by NU or CEI or
any of their respective subsidiaries, as applicable) for all purposes for which
such service was taken into account or recognized by CEI or NU or their
respective subsidiaries, as the case may be, but not to the extent crediting
such service would result in duplication of benefits (including for benefit
accrual purposes under defined benefit pension plans).

    (d) CONTINUATION OF BENEFITS. Subject to Applicable Law and obligations
under applicable collective bargaining agreements, the Company shall maintain
for a period of at least one year after the Closing Date, without interruption,

maintained by the Company, or established to replace any CEI or NU welfare
plans, funds or programs, in which such CEI or NU employees may be eligible to
participate after the Closing Date, other than limitations or waiting periods
that are already in effect with respect to such employees and that have not been
satisfied as of the Closing Date and (ii) provide each CEI and NU employee with
credit for any co-payments and deductibles paid by such employee prior to the

Time which rights are now existing in favor of the current or former trustees,
directors or officers of CEI and the CEI Subsidiaries or NU and the NU
Subsidiaries, as the case may be, as provided in their respective certificates
of incorporation or by-laws (or comparable organizational documents) shall
survive the Mergers and shall continue in full force and effect in accordance
with their terms (PROVIDED that in any event all such rights shall continue for
a period of at least six years after the Effective Time). In addition, from and
after the Effective Time, trustees, directors and officers of CEI or NU or their
respective subsidiaries who become directors or officers of the Company will be

                                       43
<PAGE>
    (b) For six years after the Effective Time, the Company shall maintain in
effect the trustees', directors' and officers' liability (and fiduciary)
insurance policies currently maintained by NU and CEI covering acts or omissions
occurring prior to the Effective Time with respect to those persons who are
currently covered by CEI's and NU's respective trustees', directors' and
officers' liability insurance policies on terms with respect to such coverage
and amount no less favorable than those of the relevant policy in effect on the
date of this Agreement. If such insurance coverage cannot be obtained at all,
the Company shall maintain the most advantageous policies of trustees',
directors' and officers' insurance obtainable.

    (c) In the event the Company 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

the successors and assigns of the Company shall assume the obligations set forth
in this Section 5.08.

    (d) The provisions of Section 5.08(a) (i) are intended to be for the benefit
of, and will be enforceable by, each indemnified party, his or her heirs and his
or her representatives and (ii) are in addition to, and not in substitution for,
any other rights to indemnification or contribution that any such person may

laws of the applicable State, a conflict of interest in representing any
particular indemnified party.

Company and with each other in the filing of such returns, including supplying
in a timely manner a complete list of all real property interests held by CEI or

to NU or any of the NU Subsidiaries or has been made directly to the NU
Shareholders generally or any person shall have publicly announced an intention
(whether or not conditional and whether or not such NU Takeover Proposal shall
have been rejected or shall have been withdrawn or terminated prior to the NU
Shareholders Meeting or any termination of this Agreement) to make a NU Takeover
Proposal and thereafter this Agreement is terminated by either CEI or NU
pursuant to Section 7.01(b)(i) or by CEI pursuant to Section 7.01(d),
(ii) prior to or during the NU Shareholders Meeting (or any subsequent meeting
of the NU Shareholders at which it is proposed that the NU Merger be approved),

                                       44
<PAGE>
CEI a fee equal to $110 million (the "TERMINATION FEE"), payable by wire
transfer of same day funds; PROVIDED, HOWEVER, that no Termination Fee shall be
payable to CEI pursuant to clauses (i) or (ii) of this paragraph (b) unless and
until within 24 months of such termination NU or any NU Subsidiary (x) enters
into any NU Acquisition Agreement or (y) consummates any NU Takeover Proposal
(for the purposes of the foregoing proviso the terms "NU ACQUISITION AGREEMENT"
and "NU TAKEOVER PROPOSAL" shall have the meanings assigned to such terms in
Section 4.02 except that the references to "15%" in the definition of "NU
Takeover Proposal" in Section 4.02(a) shall be deemed to be references to
"35%"), in which event the Termination Fee shall be immediately payable upon the
first to occur of such events set forth in the preceding clauses (x) and (y).

    (c) If this Agreement is terminated by CEI or NU pursuant to
Section 7.01(b)(ii), by NU pursuant to Section 7.01(f), by CEI pursuant to
Section 7.01(c) or by CEI pursuant to Section 7.01(d) or if NU is otherwise

transfer of same day funds, an expense reimbursement fee of $20 million for fees
and expenses incurred, or paid by or on behalf of, CEI in connection with the
Mergers or the transactions contemplated by this Agreement. The payment of such
expense reimbursement fee shall not affect the extent to which, or the amount
of, the Termination Fee which NU may separately be required to pay to CEI
pursuant to Section 5.09(b).

    (d) If this Agreement is terminated by NU pursuant to
Section 7.01(b)(iii) or by NU pursuant to Section 7.01(e), CEI shall immediately
pay to NU, by wire transfer of same day funds, an expense reimbursement fee of
$20 million for fees and expenses incurred, or paid by or on behalf of, NU in
connection with the Mergers or the transactions contemplated by this Agreement.

    (e) NU acknowledges that the agreements contained in Sections 5.09(b) and
5.09(c) are an integral part of the transactions contemplated by this Agreement,
and that, without these agreements, CEI would not enter into this Agreement;
accordingly, if NU fails promptly to pay the amount due pursuant to
Section 5.09(b) and 5.09(c), and, in order to obtain such payment, CEI commences
a suit that results in a judgment against NU for any of the amounts set forth in
Section 5.09(b) or 5.09(c), as the case may be, NU shall pay to CEI its costs
and expenses (including attorneys' fees and expenses) in connection with such
suit, together with interest on such amounts at the prime rate of The Chase
Manhattan Bank in effect on the date such payment was required to be made.

    SECTION 5.10.  PUBLIC ANNOUNCEMENTS.  CEI and NU will consult with each
other before issuing, and provide each other the opportunity to review, comment
upon and concur with, any press release or other public statements with respect
to the transactions contemplated by this Agreement, including the Mergers, and
shall not issue any such press release or make any such public statement prior

parties agree that the initial press release to be issued with respect to the
transactions contemplated by this Agreement shall be in the form heretofore
agreed to by the parties.

Agreement, NU shall deliver to CEI, and CEI shall deliver to NU, a letter
identifying all persons who are, at the time this Agreement is submitted for
adoption by the respective shareholders of CEI and NU, "affiliates" of CEI or
NU, as the case may be, for purposes of Rule 145 under the Securities Act. CEI
and NU shall use their respective reasonable best efforts to cause each such
person to deliver to the Company as of the Closing Date, a written agreement
substantially in the form attached hereto as Exhibit D-1 in the case of NU and
Exhibit D-2 in the case of CEI.

    SECTION 5.12.  NYSE LISTING.  The Company shall use its reasonable best

to participate in the defense of any shareholder litigation against NU or any of
its trustees or officers relating to the transactions contemplated by this
Agreement.

their respective subsidiaries to, (i) timely file with the relevant taxing
authority all material Tax returns and reports required to be filed by it, on a
basis consistent with the elections, accounting methods, conventions and
principles of taxation used for the most recent taxable periods for which Tax
returns involving similar Tax items have been filed, and in a manner that does
not unreasonably accelerate deductions or defer income, (ii) timely pay all
Taxes due and payable, or establish proper reserves therefor in its books and
records in accordance with GAAP, (iii) make adequate provision on its books and
records, to the extent required in accordance with GAAP, for all Taxes due and

action, suit, proceeding, claim or audit pending against or with respect to it
or any of its subsidiaries in respect of any material Taxes.

    (b) Each of CEI and NU shall not, and shall not permit any of their
respective subsidiaries to, take any action, or fail to take any action, that
would, or could reasonably be expected to, prevent (i) the Mergers from
constituting a transaction described in Section 351 of the Code, (ii) the CEI
Merger from constituting a transaction described in Section 368(a) of the Code
or (iii) CEI or NU from obtaining the opinions of counsel referred to in
Sections 6.02(c) and 6.03(c).

    SECTION 5.15.  STANDSTILL AGREEMENTS; CONFIDENTIALITY AGREEMENTS.  During
the period from the date of this Agreement through the Effective Time, NU shall
not terminate, amend, modify or waive any provision of any confidentiality or
standstill agreement to which it or any of its respective subsidiaries is a
party, PROVIDED that NU may terminate, amend, modify or waive any provision of,
any confidentiality agreement relating solely to the sale of the NU
Subsidiaries' generation assets, including any NU Nuclear Facilities, other than
any standstill provisions contained in any such confidentiality agreement.
During such period, NU shall enforce, to the fullest extent permitted under
Applicable Law, the provisions of any such agreement, including by seeking to
obtain injunctions to prevent any breaches of such agreements and to enforce
specifically the terms and provisions thereof in any court of the United States
of America or of any state having jurisdiction.

    SECTION 5.16.  RIGHTS AGREEMENT.  NU shall take all action requested in
writing by CEI in order to render the NU Rights under the NU Rights Agreement
inapplicable to the Mergers and the other transactions contemplated by the
Agreement. Except as approved in writing by CEI, NU shall not (i) amend the NU
Rights Agreement, (ii) redeem the NU Rights or (iii) take any action with
respect to, or make any determination under, the NU Rights Agreement. If any
"Distribution Date", "Shares Acquisition Date" or "Section 11(a)(ii) Event" (as
each such term is defined in the NU Rights Agreement) occurs under the Rights
Agreement at any time during the period from the date of this Agreement to the
Effective Time, CEI and NU shall make such adjustments as CEI and NU shall
mutually agree so as to preserve the economic benefits that CEI and NU each
reasonably expected on the date of this Agreement to receive as a result of the
consummation of the Mergers and the other transactions contemplated by the
Agreement.

    (e) STATUTORY APPROVALS. The CEI Statutory Approvals and the NU Statutory
Approvals shall have been obtained at or prior to the Effective Time, such

(C) a Material Adverse Effect on the Company and its prospective subsidiaries
taken as a whole. A "FINAL ORDER" means action by the relevant Governmental

Shareholders under the NU Rights Agreement, including a "Distribution Date", a

defined in the NU Rights Agreement) or a "flip-in" or "flip-over" event as
commonly described in

following conditions:

    (a) REPRESENTATIONS AND WARRANTIES. The representations and warranties of
CEI set forth herein shall be true and correct both when made and at and as of

expressly made as of an earlier date, in which case as of such date), except
where the failure of such representations and warranties to be so true and
correct (without giving effect to any limitation as to "materiality" or
"Material Adverse Effect" set forth therein) would not have, individually or in
the aggregate, a Material Adverse Effect on CEI.

    (b) PERFORMANCE OF OBLIGATIONS OF CEI. CEI shall have performed in all
material respects all obligations required to be performed by it under this
Agreement at or prior to the Closing Date.

entitled to rely upon customary representations of the parties hereto,
substantially in the form of Exhibits E, F and G hereto.

    (d) NO MATERIAL ADVERSE CHANGE. From and after the date of this Agreement,
no Material Adverse Change with respect to CEI (including the discovery of, any
deterioration in, or any worsening of, any change, effect, event, occurrence or

occurred.

    (e) STATUTORY APPROVALS. The CEI Statutory Approvals and the NU Statutory
Approvals shall have been obtained at or prior to the Effective Time, such
approvals shall have become Final Orders and neither such Final Orders nor any
order, law or regulation of any Governmental Entity shall impose terms or
conditions that would have, individually or in the aggregate, (A) a Material
Adverse Effect on CEI or (B) a Material Adverse Effect on the Company and its
prospective subsidiaries taken as a whole.

    (f) CLOSING CERTIFICATES. NU shall have received a certificate signed by an
executive officer of CEI, dated the Closing Date, to the effect that, to the

    terminate this Agreement pursuant to this Section 7.01(b)(i) shall not be
    available to any party whose failure to perform any of its obligations under

    Merger and the NU Merger set forth in Sections 6.01(b) and

    pursuant to this Section 7.01(b)(iv) shall have used its reasonable best
    efforts to prevent the entry of and to remove such Restraint;

    (c) by CEI, if NU shall have breached or failed to perform in any material
respect any of its representations, warranties, covenants or other agreements
contained in this Agreement (other than Section 4.02), which breach or failure
to perform (A) would give rise to the failure of a condition set forth in
Section 6.02(a) or (b), and (B) is incapable of being cured by NU or is not
cured by NU within a reasonable period of time following receipt of written
notice from CEI of such breach or failure to perform;

    (d) by CEI, if NU or any of its trustees or officers breaches or fails to
perform in any material respect any of its covenants or agreements contained in
Section 4.02;

    (e) by NU, if CEI shall have breached or failed to perform in any material
respect any of its representations, warranties, covenants or other agreements
contained in this Agreement, which breach or failure to perform (A) would give
rise to the failure of a condition set forth in Section 6.03(a) or (b), and

payment of the Termination Fee, of Section 5.09.

    SECTION 7.02.  EFFECT OF TERMINATION.  In the event of termination of this
Agreement by either NU or CEI as provided in Section 7.01, this Agreement shall
forthwith become null and void and have no effect, without any liability or
obligation on the part of CEI or NU, other than the provisions of
Section 3.01(q), Section 3.02(o), the penultimate sentence of Section 5.04(a),
Section 5.09, this Section 7.02 and Article VIII, which provisions shall survive
such termination, and except to the extent that such termination results from
the willful and material breach by a party of any of its representations,
warranties, covenants or agreements set forth in this Agreement, in which case
such termination shall not relieve any party of any liability or damages
resulting from its willful and material breach of this Agreement (including any
such case in which a Termination Fee or any expense reimbursement fee is payable
pursuant to Section 5.09), to the extent any such liability or damage suffered
by the party entitled to such payment exceeds the amount of such payment
(including, in the case of CEI, the amount of the Termination Fee (to the extent
payable) and any expense reimbursement fee payable to CEI pursuant to
Section 5.09).

    SECTION 7.03.  AMENDMENT.  This Agreement may be amended by the parties at
any time before or after the NU Shareholder Approval or the CEI Shareholder
Approval; PROVIDED, HOWEVER, that after any such approval, there shall not be

representations and warranties of the other parties contained in this Agreement
or in any document delivered pursuant to this Agreement or (c) subject to the
proviso of Section 7.03, waive compliance by the other parties with any of the
agreements or conditions contained in this Agreement. Any agreement on the part
of a party to any such extension or waiver shall be valid only if set forth in
an instrument in writing signed on behalf of such party. The failure of any
party to this Agreement to assert any of its rights under this Agreement or
otherwise shall not constitute a waiver of such rights.

    SECTION 7.05.  PROCEDURE FOR TERMINATION, AMENDMENT, EXTENSION OR WAIVER.  A
termination of this Agreement pursuant to Section 7.01, an amendment of this
Agreement pursuant to Section 7.03 or an extension or waiver pursuant to

by its Board of Trustees or the duly authorized committee or designee of its
Board of Trustees to the extent permitted by law and the Trust Agreement and, in
the case of CEI, action by its Board of Directors or the duly authorized

contemplates performance after the Effective Time.

counterparts, all of which shall be considered one and the same agreement and

Agreement (including the documents and instruments referred to herein) and the
Confidentiality Agreement (except for paragraph 9 thereof) (i) constitutes the
entire agreement, and supersedes all prior agreements and understandings, both

extent that the laws of the State of Delaware govern the CEI Merger or the laws
of the Commonwealth of Massachusetts govern the NU Merger regardless, in each
case, of the laws that might otherwise govern under applicable principles of
conflict of laws.

    SECTION 8.08.  ASSIGNMENT.  Neither this Agreement nor any of the rights,
interests or obligations under this Agreement shall be assigned, in whole or in
part, by operation of law or otherwise by any of the parties hereto without the
prior written consent of the other party. Any attempted or purported assignment
in violation of the preceding sentence shall be null and void and of no effect
whatsoever. Subject to the preceding two sentences, this Agreement shall be
binding upon, inure to the benefit of, and be enforceable by, the parties and
their respective successors and assigns.

    SECTION 8.09.  ENFORCEMENT.  The parties agree that irreparable damage would
occur and that the parties would not have any adequate remedy at law in the
event that any of the provisions of this Agreement were not performed in
accordance with their specific terms or were otherwise breached. It is
accordingly agreed that the parties shall be entitled to an injunction or
injunctions to prevent breaches of this Agreement and to enforce specifically
the terms and provisions of this Agreement in the Federal court located in the
Borough of Manhattan in The City of New York or if such court does

                                       52
<PAGE>
not have jurisdiction, in any Federal court having jurisdiction, or if no
Federal court has jurisdiction, in any state court having jurisdiction, this
being in addition to any other remedy to which they are entitled at law or in
equity. In addition, each of the parties hereto (a) consents to submit itself to
the personal jurisdiction of the Federal court located in the Borough of
Manhattan in The City of New York or if such court does not have jurisdiction,
in any Federal court having jurisdiction, or if no Federal court has
jurisdiction, in any state court having jurisdiction in the event any dispute
arises out of this Agreement or any of the transactions contemplated by this
Agreement, (b) agrees that it will not attempt to deny or defeat such personal
jurisdiction by motion or other request for leave from any such court, and
(c) agrees that it will not bring any action relating to this Agreement or any
of the transactions contemplated by this Agreement in any court other than a
Federal court sitting in the Borough of Manhattan in The City of New York or if
such court does not have jurisdiction, in any Federal court having jurisdiction,
or if no Federal court has jurisdiction, in any state court having jurisdiction.

    SECTION 8.10.  SEVERABILITY.  If any term or other provision of this
Agreement is invalid, illegal or incapable of being enforced by any rule of law
or public policy, all other conditions and provisions of this Agreement shall
nevertheless remain in full force and effect. Upon such determination that any
term or other provision is invalid, illegal or incapable of being enforced, the
parties hereto shall negotiate in good faith to modify this Agreement so as to
effect the original intent of the parties as closely as possible to the fullest
extent permitted by Applicable Law in an acceptable manner to the end that the
transactions contemplated hereby are fulfilled to the extent possible.

    SECTION 8.11.  TRUSTEE AND SHAREHOLDER LIABILITY.  No trustee or NU
Shareholder shall be held to any liability whatsoever for any obligation under
this Agreement, and this Agreement shall not be enforceable against any such
trustee or NU Shareholder in their or his or her individual capacities or
capacity. This Agreement shall be enforceable against the trustees of NU only as
such, and every person, firm, association, trust or corporation having any claim
or demand arising under this Agreement and relating to NU, the NU Shareholders
or trustees shall look solely to the trust estate of NU for the payment or
satisfaction thereof.

State of Delaware and by the unanimous written consent of the stockholders of
the Corporation, restates and integrates and further amends the provisions of

    The purpose of the Corporation is to engage in any lawful act or activity
for which corporations may be organized under the General Corporation Law of the
State of Delaware.

                                 ARTICLE FOURTH

to each such class or series, to determine by resolution or resolutions the

class or series, the voting powers, if any, of the shares of such class or
series, and the preferences and relative, participating, optional or other
special rights, if any, and any qualifications, limitations or restrictions

                                                                               2

    (c) The powers, preferences and relative, participating, optional and other
special rights of each class or series of Preferred Stock and the
qualifications, limitations or restrictions thereof, if any, may differ from
those of any and all other classes or series at any time outstanding.

    (d) Subject to applicable law and the rights, if any, of the holders of any
class or series of Preferred Stock or any class or series of stock having a
preference over or the right to participate with the Common Stock with respect
to the payment of dividends, dividends may be declared and paid on the Common
Stock at such times and in such amounts as the Board of Directors of the
Corporation in its discretion shall determine. Nothing in this ARTICLE FOURTH
shall limit the power of the Board of Directors to create a class or series of
Preferred Stock with dividends the rate of which is calculated by reference to,
and the payment of which is concurrent with, dividends on shares of Common
Stock.

    (e) In the event of the voluntary or involuntary liquidation, dissolution or
winding up of the Corporation, subject to the rights of the holders of any class
or series of the Preferred Stock, the net assets of the Corporation available
for distribution to stockholders of the Corporation shall be distributed PRO
RATA to the holders of the Common Stock in accordance with their respective
rights and interests. If the assets of the Corporation are not sufficient to pay
the amounts, if any, owing to holders of shares of Preferred Stock in full,
holders of all shares of Preferred Stock will participate in the distribution of
assets ratably in proportion to the full amounts to which they are entitled or
in such order or priority, if any, as will have been fixed in the resolution or
resolutions providing for the issue of the class or series of Preferred Stock.
Neither the merger or consolidation of the Corporation into or with any other
corporation, nor a sale, transfer or lease of all or part of its assets, will be
deemed a liquidation, dissolution or winding up of the Corporation within the
meaning of this paragraph except to the extent specifically provided for herein.
Nothing in this ARTICLE FOURTH shall limit the power of the Board of Directors
to create a class or series of Preferred Stock for which the amount to be
distributed upon any liquidation, dissolution or winding up of the Corporation
is calculated by reference to, and the payment of which is concurrent with, the
amount to be distributed to the holders of shares of Common Stock.

    (f) Except as otherwise required by law, as otherwise provided herein or as
otherwise determined by the Board of Directors as to the shares of any class or
series of Preferred Stock prior to the issuance of any such shares, the holders
of Preferred Stock shall have no voting rights and shall not be entitled to any
notice of meetings of stockholders.

    (g) Except as otherwise required by law and subject to the rights of the
holders of any class or series of Preferred Stock, with respect to all matters
upon which stockholders are entitled to vote or to which stockholders are
entitled to give consent, the holders of any outstanding shares of Common Stock
shall vote together as a class, and every holder of Common Stock shall be
entitled to cast thereon one vote in person or by proxy for each share of Common
Stock standing in such holder's name on the books of the Corporation; PROVIDED,
HOWEVER, that, except as otherwise required by law, holders of Common Stock, as
such, shall not be entitled to vote on any amendment to this Certificate of
Incorporation (including any certificate of designations relating to any class
or series of Preferred Stock) that relates solely to the terms of one or more
outstanding class or series of Preferred Stock if the holders of such affected
class or series are entitled, either separately or together with the holders of
one or more other such class or series, to vote thereon pursuant to this
Certificate of Incorporation (including any certificate of designations relating
to any class or series of Preferred Stock) or pursuant to applicable law.
Subject to the rights of the holders of any class or series of Preferred Stock,
stockholders of the Corporation shall not have any preemptive rights to
subscribe for additional issues of stock of the Corporation and no stockholder
will be permitted to cumulate votes at any election of directors.

directors pursuant to the provisions of this ARTICLE FIFTH, the Board of
Directors shall consist of   -  directors (as so adjusted, the "entire Board of
Directors"). The Board of Directors may increase or decrease the number of
directors by resolution adopted by a majority of the entire Board of Directors;
PROVIDED, HOWEVER, that no decrease in the number of directors so made by the
Board of Directors shall shorten the term of any incumbent director. Except as
otherwise provided by or pursuant to the provisions of ARTICLE FOURTH of this
Certificate of Incorporation with respect to any directors elected by the
holders of any class or series of Preferred Stock pursuant to the terms of this
Certificate of Incorporation, at each annual meeting of the stockholders of the
Corporation, the date of which shall be fixed by or pursuant to the By-laws of
the Corporation, directors shall be elected and each director shall hold office
until the next annual meeting of stockholders and until his or her successor is
duly elected and qualified, or until his or her earlier death, incapacity,
resignation or removal from office in accordance with applicable law or pursuant
to an order of a court of competent jurisdiction. The election of directors need
not be by written ballot.

    (b) Except as otherwise provided for or fixed by or pursuant to the
provisions of ARTICLE FOURTH of this Certificate of Incorporation relating to
the rights of the holders of any class or series of Preferred Stock, any vacancy
on the Board of Directors of the Corporation resulting from death, incapacity,
resignation, removal or other cause and any newly created directorship resulting
from any increase in the authorized number of directors between annual meetings
of stockholders shall be filled only by the vote of a majority of the directors
then in office, even though less than a quorum, and any director so chosen shall
hold office until the next annual meeting of stockholders and until his or her
successor is duly elected and qualified or his or her earlier death, incapacity,
resignation or removal from office in accordance with applicable law or pursuant
to an order of a court of competent jurisdiction.

                                 ARTICLE SIXTH

    (a) Subject to the rights of the holders of any class or series of Preferred
Stock, any action required or permitted to be taken by the stockholders of the
Corporation must be effected at a duly called annual or special meeting of
stockholders of the Corporation and may not be effected by any consent in
writing by such stockholders. Subject to the rights of the holders of any class
or series of Preferred Stock and except as expressly set forth in the By-laws of
the Corporation, special meetings of stockholders of the Corporation may be
called only by the Board of Directors pursuant to a resolution approved by a
majority of the entire Board of Directors.

    (b) Notwithstanding the foregoing, whenever the holders of any one or more
class or series of Preferred Stock issued by the Corporation, if any, shall have
the right, voting separately by class or series, as applicable, to elect
directors at an annual or special meeting of stockholders, the calling of
special meetings of the holders of such class or series shall be governed by the
terms of the applicable resolution or resolutions of the Board of Directors
adopted pursuant to ARTICLE FOURTH of this Certificate of Incorporation.

                                ARTICLE SEVENTH

    In furtherance and not in limitation of the powers conferred upon it by law,
the Board of Directors of the Corporation is expressly authorized to adopt,
repeal, alter or amend the By-laws of the Corporation by the vote of a majority
of the entire Board of Directors.

                                 ARTICLE EIGHTH

    Except to the extent elimination or limitation of liability is not permitted
by applicable law, no director of the Corporation shall be personally liable to
the Corporation or its stockholders for monetary damages for any breach of
fiduciary duty in such capacity. Any repeal or modification of this ARTICLE
EIGHTH by the stockholders of the Corporation shall not adversely affect any
right or protection of a director of the Corporation existing at the time of
such repeal or modification with respect to acts or omissions occurring prior to
such repeal or modification.

                           CONSOLIDATED EDISON, INC.
            (A CORPORATION ORGANIZED UNDER THE LAWS OF THE STATE OF
                          DELAWARE, THE "CORPORATION")
                            (EFFECTIVE AS OF   -  )

1. STOCKHOLDERS.

    1.1  PLACE OF STOCKHOLDERS' MEETINGS.  All meetings of the stockholders of
the Corporation shall be held at such place or places, within or outside the
State of Delaware, as may be fixed by the Corporation's Board of Directors (the
"Board", and each member thereof a "Director") from time to time or as shall be
specified in the respective notices thereof.

    1.2  DAY AND TIME OF ANNUAL MEETINGS OF STOCKHOLDERS.  An annual meeting of
stockholders shall be held at such place (within or outside the State of
Delaware), date and hour as shall be determined by the Board and designated in
the notice thereof. Any previously scheduled annual meeting of stockholders may
be postponed by action of the Board taken prior to the time previously scheduled
for such annual meeting of stockholders.

    1.3  PURPOSES OF ANNUAL MEETINGS.  (a) Subject to the rights of the holders
of any class or series of Preferred Stock of the Corporation, at each annual
meeting, the stockholders shall elect the Directors. At any such annual meeting
any business properly brought before the meeting may be transacted.

    (b) To be properly brought before an annual meeting, business must be
(i) specified in the notice of the meeting (or any supplement thereto) given by
or at the direction of the Board, (ii) otherwise properly brought before the
meeting by or at the direction of the Board or (iii) otherwise properly brought
before the meeting by a stockholder who is a holder of record at the time of the
giving of notice provided for in this Section 1.3(b), who is entitled to vote at
the meeting and who complies with the procedures set forth in this
Section 1.3(b). For business to be properly brought before an annual meeting by
a stockholder, the stockholder must have given written notice thereof, either by
personal delivery or by United States mail, postage prepaid, to the Secretary of
the Corporation (the "Secretary") at the principal executive offices of the
Corporation, not less than 90 days nor more than 120 days prior to the
anniversary date of the immediately preceding annual meeting (PROVIDED, that the
first such anniversary date occurring after the effective date of these By-laws
shall be deemed to be   -  ). Any such notice shall set forth as to each matter
the stockholder proposes to bring before the annual meeting (i) a brief
description of the business desired to be brought before the annual meeting and
the reasons for conducting such business at the annual meeting, and, in the
event that such business includes a proposal to amend either the Restated
Certificate of Incorporation of the Corporation (the "Certificate") or these
By-laws, the text of the proposed amendment; (ii) the name and address, as they
appear on the Corporation's books, of the stockholder proposing such business;
(iii) the class and number of shares of the Corporation which are beneficially
owned by the stockholder; (iv) any material interest of the stockholder in such
business; and (v) if the stockholder intends to solicit proxies in support of
such stockholder's proposal, a representation to that effect. The foregoing
notice requirements shall be deemed satisfied by a stockholder if the
stockholder has notified the Corporation of his or her intention to present a
proposal at an annual meeting and such stockholder's proposal has been included
in a proxy statement that has been prepared by management of the Corporation to
solicit proxies for such annual meeting; PROVIDED, HOWEVER, that if such
stockholder does not appear or send a qualified representative to present such
proposal at such annual meeting, the Corporation need not present such proposal
for a vote at such meeting, notwithstanding that proxies in respect of such vote
may have been received by the Corporation. No business shall be conducted at an
annual meeting of stockholders except in accordance with this Section 1.3(b),
and the presiding officer of any annual meeting of stockholders may refuse to
permit any business to be brought before an annual meeting without compliance
with the foregoing procedures or if the

stockholder solicits proxies in support of such stockholder's proposal without
such stockholder having made the representation required by clause (v) of the
second preceding sentence.

    1.4  SPECIAL MEETINGS OF STOCKHOLDERS.  (a) Except as otherwise expressly
required by the Certificate or by applicable law and subject to the rights of
the holders of any class or series of Preferred Stock of the Corporation,
special meetings of the stockholders or of any class or series entitled to vote
may be called for any purpose or purposes by a majority vote of the entire Board
of Directors, as defined in the Certificate (the "entire Board"), or, subject to
the procedures set forth in this Section 1.4(a), by stockholders representing
25% or more of the voting power of all outstanding shares of stock of the
Corporation entitled to vote generally in the election of Directors. At any such
special meeting any business properly brought before the meeting may be
transacted. Upon request in writing sent by registered mail to the Chairman of
the Board by any stockholder or stockholders entitled to call a special meeting
of stockholders pursuant to this Section 1.4(a), the Board shall determine a
place (within or outside the State of Delaware) and time for such meeting after
the receipt and determination of the validity of such request, and a record date
for the determination of stockholders entitled to vote at such meeting in the
manner set forth in Section 1.12 hereof. Following such receipt and
determination, the Secretary shall cause notice to be given to the stockholders
entitled to vote at such meeting, in the manner set forth in Section 1.5 hereof,
that such meeting will be held at the place and time so determined.

    (b) To be properly brought before a special meeting, business must be
(i) specified in the notice of the meeting (or any supplement thereto) given by
or at the direction of the Board, (ii) otherwise properly brought before the
meeting by or at the direction of the Board or (iii) otherwise properly brought
before the meeting by a stockholder who is a holder of record at the time of the
giving of notice provided for in this Section 1.4(b), who is entitled to vote at
the meeting and who complies with the procedures set forth in this
Section 1.4(b). For business to be properly brought before a special meeting by
a stockholder, the stockholder must have given written notice thereof, either by
personal delivery or by United States mail, postage prepaid, to the Secretary at
the principal executive offices of the Corporation, not earlier than the 90th
day prior to such special meeting and not later than the close of business on
the later of the 60th day prior to such special meeting or the tenth day
following the day on which public announcement of the date of the special
meeting is first made. Any such notice shall set forth as to each matter the
stockholder proposes to bring before the special meeting (i) a brief description
of the business desired to be brought before the special meeting and the reasons
for conducting such business at the special meeting, and, in the event that such
business includes a proposal to amend either the Certificate or these By-laws,
the text of the proposed amendment; (ii) the name and address, as they appear on
the Corporation's books, of the stockholder proposing such business; (iii) the
class and number of shares of the Corporation which are beneficially owned by
the stockholder; (iv) any material interest of the stockholder in such business;
and (v) if the stockholder intends to solicit proxies in support of such
stockholder's proposal, a representation to that effect. The foregoing notice
requirements shall be deemed satisfied by a stockholder if the stockholder has
notified the Corporation of his or her intention to present a proposal at a
special meeting and such stockholder's proposal has been included in a proxy
statement that has been prepared by management of the Corporation to solicit
proxies for such special meeting; PROVIDED, HOWEVER, that if such stockholder
does not appear or send a qualified representative to present such proposal at
such special meeting, the Corporation need not present such proposal for a vote
at such meeting, notwithstanding that proxies in respect of such vote may have
been received by the Corporation. No business shall be conducted at a special
meeting of stockholders except in accordance with this Section 1.4(b), and the
presiding officer of any special meeting of stockholders may refuse to permit
any business to be brought before a special meeting without compliance with the
foregoing procedures or if the stockholder solicits proxies in support of such
stockholder's proposal without such stockholder having made the representation
required by clause (v) of the second preceding sentence.

required or permitted by the Certificate or by applicable law, not less than ten

presence in person or by proxy of stockholders entitled to cast a majority of
votes thereat shall constitute a quorum for the entire meeting, notwithstanding
the withdrawal of stockholders entitled to cast a sufficient number of votes in
person or by proxy to reduce the number of votes represented at the meeting
below a quorum. Shares of the Corporation's stock belonging to the Corporation
or to another corporation, if a majority of the shares entitled to vote in an
election of the directors of such other corporation is held by the Corporation,
shall neither be counted for the purpose of determining the presence of a quorum

not a quorum is present, the officer presiding thereat shall have power to

than announcement at the meeting at which an adjournment is taken shall not be
required to be given, except as provided in Section 1.6(d) below and except
where expressly required by applicable law.

as originally noticed shall be entitled to vote at any adjournment or
adjournments thereof unless a new record date is fixed by the Board.

    (d) If an adjournment is for more than 30 days, or if after the adjournment
a new record date is fixed for the adjourned meeting, a notice of the adjourned
meeting shall be given in the manner specified in Section 1.5 to each
stockholder of record entitled to vote at the adjourned meeting.

    1.7  CHAIRMAN OF THE BOARD AND SECRETARY OF MEETING.  The Chairman of the
Board or, in his or her absence, another officer of the Corporation designated
by the Chairman of the Board, shall preside at meetings of the stockholders. The

Secretary, an Assistant Secretary of the Corporation shall so act, or if neither
is present, then the presiding officer may appoint a person to act as secretary
of the meeting.

    1.8  VOTING BY STOCKHOLDERS.  (a) Except as otherwise expressly required by
the Certificate or by applicable law, at every meeting of the stockholders each
stockholder of record shall be entitled to the number of votes specified in the

applicable certificate of designations providing for the creation of such
series), in person or by proxy, for each share of stock standing in his or her
name on the books of the Corporation on the date fixed pursuant to the
provisions of Section 1.12 of these By-laws as the record date for the
determination of the stockholders who shall be entitled to receive notice of and
to vote at such meeting.

    (b) When a quorum is present at any meeting of the stockholders, all
questions shall be decided by the vote of a majority in voting power of the
stockholders present in person or by proxy and entitled to vote at such meeting,
unless the question is one upon which by express provision of law, the rules or
regulations of any stock exchange or governmental or regulatory body applicable
to the Corporation, the Certificate or these By-laws, a different vote is
required, in which case such express provision shall govern and control the
decision of such question.

entities to assist the inspectors in the performance of the duties of the
inspectors.

    (c) If there are three or more inspectors, the act of a majority of the
inspectors shall govern. On request of the officer presiding at such meeting,
the inspectors shall make a report of any challenge, question or matter
determined by them and execute a certificate of any fact found by them. Any
report or certificate made by them shall be prima facie evidence of the facts
therein stated and of the vote as certified by them, and such report or
certificate shall be filed with the minutes of such meeting.

    1.11  LIST OF STOCKHOLDERS.  (a) At least ten days before every meeting of
stockholders, the officer who has charge of the stock ledger of the Corporation

principal executive offices of the Corporation, not later than (i) with respect
to an election to be held at an annual meeting of stockholders, not less than 90

serve as a Director if so elected; and (f) if the stockholder intends to solicit
proxies in support of such stockholder's nominee(s), a representation to that
effect. The presiding officer of any meeting of stockholders to elect Directors

officer of the Corporation and who was or is involved in any manner (including,
without limitation, as a party or a witness) or is threatened to be made so
involved in any threatened, pending or completed investigation, claim, action,
suit or proceeding, whether civil, criminal, administrative or investigative
(including, without limitation, any action, suit or proceeding by or in the
right of the Corporation to procure a judgment in its favor) (each, a
"Proceeding"), by reason of the fact that such person was or is a Director or
officer of the Corporation or, while a Director or officer of the Corporation,
was or is serving at the request of the Corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise (including, without limitation, any employee benefit plan) (a
"Covered Entity"), against all expenses (including attorneys' fees), judgments,
fines and amounts paid in
<PAGE>
                                                                               8
settlement and actually and reasonably incurred by such person in connection
with such Proceeding. Any such former or present Director or officer of the
Corporation finally determined to be entitled to indemnification as provided in
this Article 4 is hereinafter called an "Indemnitee". Until such final
determination is made, such former or present Director or officer shall be a
"Potential Indemnitee" for purposes of this Article 4. Notwithstanding the
foregoing provisions of this Section 4.1(a), but subject to
Section 4.5(c)(iv) hereof, the Corporation shall not indemnify an Indemnitee
with respect to any Proceeding commenced by such Indemnitee unless the
commencement of such Proceeding by such Indemnitee has been approved by a
majority vote of the Disinterested Directors (as defined in Section 4.5(d));
PROVIDED, HOWEVER, that such approval of a majority of the Disinterested
Directors shall not be required with respect to any Proceeding commenced by such
Indemnitee after a Change in Control (as defined in Section 4.5(d)) has
occurred.

    (b) Neither the amendment or repeal of, nor the adoption of a provision
inconsistent with, any provision of this Article 4 (including, without
limitation, this Section 4.1(b)) shall adversely affect the rights of any
Director or officer under this Article 4 (i) with respect to any Proceeding
commenced or threatened prior to such amendment, repeal or adoption of an
inconsistent provision or (ii) after the occurrence of a Change in Control, with
respect to any Proceeding arising out of any action or omission occurring prior
to such amendment, repeal or adoption of an inconsistent provision, in either
case without the written consent of such Director or officer.

    4.2  INSURANCE, CONTRACTS AND FUNDING.  The Corporation may purchase and
maintain insurance to protect itself and any Director, officer, employee or
agent of the Corporation or of any Covered Entity against any expenses,
judgments, fines and amounts paid in settlement as specified in Section 4.1(a)
or Section 4.6 of this Article 4 or incurred by any such Director, officer,
employee or agent in connection with any Proceeding referred to in such
Sections, to the fullest extent permitted by applicable law. The Corporation may
enter into contracts with any Director, officer, employee or agent of the
Corporation or of any Covered Entity in furtherance of the provisions of this
Article 4 and may create a trust fund, grant a security interest or use other
means (including, without limitation, a letter of credit) to ensure the payment
of such amounts as may be necessary to effect indemnification as provided in
this Article 4.

    4.3  INDEMNIFICATION; NOT EXCLUSIVE RIGHT.  The right of indemnification
provided in this Article 4 shall not be exclusive of any other rights to which
an Indemnitee or Potential Indemnitee may otherwise be entitled, and the
provisions of this Article 4 shall inure to the benefit of the heirs and legal
representatives of any Indemnitee or Potential Indemnitee under this Article 4
and shall be applicable to Proceedings commenced or continuing after the
adoption of this Article 4, whether arising from acts or omissions occurring
before or after such adoption.

    4.4  ADVANCEMENT OF EXPENSES.  All reasonable expenses (including attorneys'
fees) incurred by or on behalf of any Potential Indemnitee in connection with
any Proceeding shall be advanced to such Potential Indemnitee by the Corporation
within 20 days after the receipt by the Corporation of a statement or statements
from such Potential Indemnitee requesting such advance or advances from time to
time, whether prior to or after final disposition of such Proceeding. Such
statement or statements shall reasonably evidence the expenses incurred by such
Potential Indemnitee and, if required by law at the time of such advance, shall
include or be accompanied by an undertaking by or on behalf of such Potential
Indemnitee to repay the amounts advanced if ultimately it should be determined
that such Potential Indemnitee is not entitled to be indemnified against such
expenses pursuant to this Article 4. Notwithstanding the foregoing provisions of
this Section 4.4, the Corporation shall not advance expenses to a Potential
Indemnitee with respect to any Proceeding commenced by such Potential Indemnitee
unless the commencement of such Proceeding by such Potential Indemnitee has been
approved by a majority vote of the Disinterested Directors; PROVIDED, HOWEVER,
that such approval of a majority of the Disinterested Directors shall not be
required with respect to any Proceeding commenced by such Potential Indemnitee
after a Change in Control has occurred.

PROCEEDINGS; REMEDIES; DEFINITIONS.  In furtherance, but not in limitation, of
the foregoing provisions of this Article 4, the

obtain indemnification under this Article 4, a Potential Indemnitee shall submit
to the Secretary a written request, including such documentation and information
as is reasonably available to the Potential Indemnitee and reasonably necessary
to determine whether and to what extent the Potential Indemnitee is entitled to
indemnification (the "Supporting Documentation"). The determination of the
Potential Indemnitee's entitlement to indemnification shall be made not later
than 60 days after the later of (A) the receipt by the Corporation of the
written request for indemnification together with the Supporting Documentation
and (B) the receipt by the Corporation of written notice of final disposition of
the Proceeding in respect of which indemnification is sought. The Secretary
shall, promptly upon receipt of such a request for indemnification, advise the
Board in writing that the Potential Indemnitee has requested indemnification.

    (ii) The Potential Indemnitee's entitlement to indemnification under this
Article 4 shall be determined in one of the following ways: (A) by a majority
vote of the Disinterested Directors, whether or not they constitute a quorum of
the Board; (B) by a committee of the Disinterested Directors designated by a
majority vote of the Disinterested Directors, whether or not they constitute a
quorum of the Board; (C) by a written opinion of Independent Counsel (as defined
in Section 4.5(d)) if (x) a Change in Control shall have occurred and the
Potential Indemnitee so requests or (y) there are no Disinterested Directors or
a majority of such Disinterested Directors so directs; (D) by the stockholders
of the Corporation; or (E) as provided in Section 4.5(b) of this Article 4.

    (iii) In the event the determination of entitlement to indemnification is to
be made by Independent Counsel pursuant to Section 4.5(a)(ii), a majority of the
Disinterested Directors (or, if there are no Disinterested Directors, the
General Counsel of the Corporation or, if the General Counsel is or was a party
to the Proceeding in respect of which indemnification is sought, the highest
ranking officer of the Corporation who is not and was not a party to such
Proceeding) shall select the Independent Counsel, but only an Independent
Counsel to which the Potential Indemnitee does not reasonably object; PROVIDED,
HOWEVER, that if a Change in Control shall have occurred, the Potential
Indemnitee shall select such Independent Counsel, but only an Independent
Counsel to which a majority of the Disinterested Directors does not reasonably
object.

    (b) PRESUMPTIONS AND EFFECT OF CERTAIN PROCEEDINGS. Except as otherwise
expressly provided in this Article 4, if a Change in Control shall have
occurred, the Potential Indemnitee shall be presumed to be entitled to
indemnification under this Article 4 (with respect to actions or omissions
occurring prior to such Change in Control) upon submission of a request for
indemnification together with the Supporting Documentation in accordance with
Section 4.5(a)(i) of this Article 4, and thereafter the Corporation shall have
the burden of proof to overcome that presumption in reaching a contrary
determination. In any event, if the person or persons empowered under
Section 4.5(a) of this Article 4 to determine entitlement to indemnification
shall not have been appointed or shall not have made a determination within
60 days after the later of (x) the receipt by the Corporation of the written
request for indemnification together with the Supporting Documentation and
(y) final disposition of the Proceeding in respect of which indemnification is
sought, the Potential Indemnitee shall be deemed to be, and shall be, entitled
to indemnification. The termination of any Proceeding, or of any claim, issue or
matter therein, by judgment, order, settlement or conviction, or upon a plea of
NOLO CONTENDERE or its equivalent, shall not, of itself, adversely affect the
right of the Potential Indemnitee to indemnification or create a presumption
that the Potential Indemnitee did not act in good faith and in a manner which
the Potential Indemnitee reasonably believed to be in or not opposed to the best
interests of the Corporation or, with respect to any criminal Proceeding, that
the Potential Indemnitee had reasonable cause to believe that his or her conduct
was unlawful.

    (c) REMEDIES. (i) In the event that a determination is made pursuant to
Section 4.5(a) of this Article 4 that the Potential Indemnitee is not entitled
to indemnification under this Article 4, (A) the Potential Indemnitee shall be
entitled to seek an adjudication of his or her entitlement to such
<PAGE>
                                                                              10
indemnification either, at the Potential Indemnitee's sole option, in (x) an
appropriate court of the State of Delaware or any other court of competent
jurisdiction or (y) an arbitration to be conducted by a single arbitrator
pursuant to the rules of the American Arbitration Association; (B) any such
judicial proceeding or arbitration shall be DE NOVO and the Potential Indemnitee
shall not be prejudiced by reason of such adverse determination; and (C) if a
Change in Control shall have occurred, in any such judicial proceeding or
arbitration, the Corporation shall have the burden of proving that the Potential
Indemnitee is not entitled to indemnification under this Article 4 (with respect
to actions or omissions occurring prior to such Change in Control).

    (ii) If a determination shall have been made or deemed to have been made,
pursuant to Section 4.5(a) or (b) of this Article 4, that the Potential
Indemnitee is entitled to indemnification, the Corporation shall be obligated to
pay the amounts constituting such indemnification within five days after such
determination has been made or deemed to have been made and shall be
conclusively bound by such determination unless (A) the Indemnitee
misrepresented or failed to disclose a material fact in making the request for
indemnification or in the Supporting Documentation or (B) such indemnification
is prohibited by applicable law. In the event that payment of indemnification is
not made within five days after a determination of entitlement to
indemnification has been made or deemed to have been made pursuant to
Section 4.5(a) or (b) of this Article 4, the Indemnitee shall be entitled to
seek judicial enforcement of the Corporation's obligation to pay to the
Indemnitee such indemnification. Notwithstanding the foregoing, the Corporation
may bring an action, in an appropriate court in the State of Delaware or any
other court of competent jurisdiction, contesting the right of the Indemnitee to
receive indemnification hereunder due to the occurrence of an event described in
clause (A) or (B) of this subsection (each, a "Disqualifying Event"); PROVIDED,
HOWEVER, that in any such action the Corporation shall have the burden of
proving the occurrence of such Disqualifying Event.

    (iii) The Corporation shall be precluded from asserting in any judicial
proceeding or arbitration commenced pursuant to this Section 4.5(c) that the
procedures and presumptions of this Article 4 are not valid, binding and
enforceable and shall stipulate in any such court or before any such arbitrator
that the Corporation is bound by all the provisions of this Article 4.

    (iv) In the event that the Indemnitee or Potential Indemnitee, pursuant to
this Section 4.5(c), seeks a judicial adjudication of or an award in arbitration
to enforce his or her rights under, or to recover damages for breach of, this
Article 4, such person shall be entitled to recover from the Corporation, and
shall be indemnified by the Corporation against, any expenses actually and
reasonably incurred by such person in connection with such judicial adjudication
or arbitration if such person prevails in such judicial adjudication or
arbitration. If it shall be determined in such judicial adjudication or
arbitration that such person is entitled to receive part but not all of the
indemnification or advancement of expenses sought, the expenses incurred by such
person in connection with such judicial adjudication or arbitration shall be
prorated accordingly.

    (d) DEFINITIONS. For purposes of this Article 4:

    (i) "Change in Control" means a change in control of the Corporation of a
nature that would be required to be reported in response to Item 6(e) (or any
successor provision) of Schedule 14A of Regulation 14A (or any amendment or
successor provision thereto) promulgated under the Securities Exchange Act of
1934, as amended (the "Act"), whether or not the Corporation is then subject to
such reporting requirement; PROVIDED that, without limitation, such a change in
control shall be deemed to have occurred if (A) any "person" (as such term is
used in Sections 13(d) and 14(d) of the Act) is or becomes the "beneficial
owner" (as defined in Rule 13d-3 under the Act), directly or indirectly, of
securities of the Corporation representing 15% or more of the voting power of
all outstanding shares of stock of the Corporation entitled to vote generally in
an election of Directors without the prior approval of at least two-thirds of
the members of the Board in office immediately prior to such acquisition;
(B) the Corporation is a party to any merger, consolidation or share exchange
(or other comparable transaction) in which the Corporation is not the continuing
or surviving corporation or pursuant to which shares of the Corporation's Common
Stock would be converted into cash, securities or other property, other than a
merger or share exchange in which the holders of the Corporation's
<PAGE>
                                                                              11
Common Stock immediately prior to the merger have the same proportionate
ownership of common stock of the surviving corporation immediately after the
merger; (C) there is a sale, lease, exchange or other transfer (in one
transaction or a series of related transactions) of all, or substantially all,
of the assets of the Corporation, or liquidation or dissolution of the
Corporation; (D) the Corporation is a party to a merger, consolidation, sale of
assets or other reorganization, or a proxy contest, as a consequence of which
members of the Board in office immediately prior to such transaction or event
constitute less than a majority of the Board thereafter; or (E) during any
period of two consecutive years, individuals who at the beginning of such period
constituted the Board (including for this purpose any new Director whose
election or nomination for election by the stockholders was approved by a vote
of at least two-thirds of the Directors then still in office who were Directors
at the beginning of such period) cease for any reason to constitute at least a
majority of the Board.

    (ii) "Disinterested Director" means a Director who is not and was not a
party to the Proceeding in respect of which indemnification is sought by the
Indemnitee or Potential Indemnitee.

    (iii) "Independent Counsel" means a law firm or a member of a law firm that
neither presently is, nor in the past five years has been, retained to
represent: (a) the Corporation or the Indemnitee or Potential Indemnitee in any
matter material to either such party or (b) any other party to the Proceeding
giving rise to a claim for indemnification under this Article 4. Notwithstanding
the foregoing, the term "Independent Counsel" shall not include any person who,
under applicable standards of professional conduct then prevailing under the law
of the State of Delaware, would have a conflict of interest in representing
either the Corporation or the Indemnitee or Potential Indemnitee in an action to
determine the Indemnitee's or Potential Indemnitee's rights under this
Article 4.

    4.6  INDEMNIFICATION OF EMPLOYEES AND AGENTS.  Notwithstanding any other
provision of this Article 4, the Corporation, to the fullest extent permitted by
applicable law, may indemnify any person other than a Director or officer of the
Corporation who is or was an employee or agent of the Corporation and who is or
was involved in any manner (including, without limitation, as a party or a
witness) or is threatened to be made so involved in any threatened, pending or
completed Proceeding, by reason of the fact that such person was or is an
employee or agent of the Corporation or was or is serving at the request of the
Corporation as a director, officer, employee or agent of a Covered Entity,
against all expenses (including attorneys' fees), judgments, fines and amounts
paid in settlement actually and reasonably incurred by such person in connection
with such Proceeding. The Corporation may also advance expenses incurred by such
employee or agent in connection with any such Proceeding, consistent with the
provisions of applicable law. If made or advanced, such indemnification shall be
made and such reasonable expenses shall be advanced pursuant to procedures to be
established from time to time by the Board.

    4.7  SEVERABILITY.  If any provision or provisions of this Article 4 shall
be held to be invalid, illegal or unenforceable for any reason whatsoever:
(i) the validity, legality and enforceability of the remaining provisions of
this Article 4 (including, without limitation, all portions of any Section of
this Article 4 containing any such provision held to be invalid, illegal or
unenforceable, that are not themselves invalid, illegal or unenforceable) shall
not in any way be affected or impaired thereby; and (ii) to the fullest extent
possible, the provisions of this Article 4 (including, without limitation, all
portions of any Section of this Article 4 containing any such provision held to
be invalid, illegal or unenforceable, that are not themselves invalid, illegal
or unenforceable) shall be construed, to the fullest extent possible, so as to
give effect to the intent manifested by the provision held invalid, illegal or
unenforceable.

corporation and address of such holder of each certificate, the number of shares
represented thereby and the date of issue thereof shall be made on the
Corporation's books. The Corporation shall be entitled to treat the holder of
record of any share of stock as the holder in fact thereof, and accordingly
shall not be bound to recognize any equitable or other claim to or interest in
any share on the part of any person, whether or not it shall have express or
other notice thereof, except as required by applicable law.

    5.3  TRANSFER OF RECORD OWNERSHIP.  Transfers of stock shall be made on the
books of the Corporation only by direction of the person named in the
certificate or such person's attorney, lawfully constituted in writing, and only
upon the surrender of the certificate therefor and a written assignment of the
shares evidenced thereby. Whenever any transfer of stock shall be made for
collateral security, and not absolutely, it shall be so expressed in the entry
of the transfer if, when the certificates are presented to the Corporation for
transfer, both the transferor and transferee request the Corporation to do so.

    5.4  TRANSFER AGENT; REGISTRAR; RULES RESPECTING CERTIFICATES.  The
Corporation shall maintain one or more transfer offices or agencies (which may
include the Corporation) where stock of the Corporation shall be transferable.

                                                         TO THE MERGER AGREEMENT

                           TRUST AGREEMENT AMENDMENTS

    The following amendments to the Trust Agreement (such term and each other
capitalized term used but not defined in this Exhibit C shall have the meaning
ascribed to such terms in the Merger Agreement, as amended and restated, to
which this Exhibit C is attached) have been approved by the affirmative vote of
two-thirds of the Trustees of Northeast Utilities ("NU") and will become
effective in accordance with Articles (39) and (40) of the Trust Agreement when
the Trust Agreement Amendments have been approved by the affirmative vote of the
holders of two-thirds of the NU Common Shares outstanding as of the date of the
NU Shareholders Meeting:

    1. Article (2) of the Trust Agreement is amended in its entirety to read:

        "(2). The number of the Trustees hereunder for each ensuing year shall
    be such as may be fixed at each annual meeting of the shareholders by a vote
    of at least a majority of the number of shares then outstanding hereunder of
    such class or classes as then have general voting power, except that if at
    any annual meeting no such number shall be so fixed then the number for the
    ensuing year shall be the same as for the year preceding. Notwithstanding
    the foregoing sentence, if a merger of the association has been approved
    pursuant to Article (11A) hereof, the number of Trustees from and after the
    effective time of such merger may be fixed by the agreement providing for
    such merger (in which case such number shall not be required to be fixed for
    any ensuing year at any annual meeting of the shareholders), including,
    without limitation, pursuant to that certain Agreement and Plan of Merger
    (the "Merger Agreement") dated as of October 13, 1999, as amended and
    restated as of January 11, 2000, among Consolidated Edison, Inc., a New York
    corporation, the association, Consolidated Edison, Inc., originally
    incorporated as CWB Holdings, Inc., a Delaware corporation and N Acquisition
    LLC, a Massachusetts limited liability company."

    2. The following new Article (11A) is added to the Trust Agreement:

        "(11A). The Trustees are authorized to take or cause to be taken all
    actions which they deem necessary or appropriate to implement and to
    effectuate a merger of the association with or into one or more domestic
    limited liability companies in accordance with Chapter 182 (Voluntary
    Associations and Certain Trusts) of the Massachusetts General Laws, if the
    same has been authorized by the affirmative vote, at a meeting (which
    meeting may have preceded the effectiveness of this Article 11A) duly called
    for such purpose, of two-thirds of all shares previously issued and
    outstanding as of the date of such meeting of such class or classes as have
    general voting power, including, without limitation, the series of
    transactions provided for in the Merger Agreement. Upon the effectiveness of
    any such merger, the rights of the holders of each class of shares of the
    association shall be governed by the terms of the agreement effecting such
    merger, including the Merger Agreement in the case of the series of
    transactions provided for therein."

Dear Sirs:

    The undersigned refers to the Agreement and Plan of Merger dated as of
October 13, 1999, as amended and restated as of January 11, 2000 (the "MERGER
AGREEMENT"), among Consolidated Edison, Inc., a New York corporation ("CEI"),
Northeast Utilities, a Massachusetts business trust ("NU"), Consolidated
Edison, Inc., originally incorporated as CWB Holdings, Inc., a Delaware
corporation ("NEW CEI"), and N Acquisition LLC, a Massachusetts limited
liability company ("MERGER LLC"). Capitalized terms used but not defined in this
letter have the meanings given such terms in the Merger Agreement.

    The undersigned, a holder of shares of NU Common Shares, is entitled to
receive in connection with the NU Merger shares of Company Common Stock. The
undersigned acknowledges that the undersigned may be deemed an "affiliate" of NU
within the meaning of Rule 145 ("RULE 145") promulgated under the Securities
Act, although nothing contained herein should be construed as an admission of
such fact.

    If in fact the undersigned were an affiliate under the Securities Act, the
undersigned's ability to sell, assign or transfer the Company Common Stock
received by the undersigned in exchange for any shares of NU Common Shares
pursuant to the NU Merger may be restricted unless such transaction is
registered under the Securities Act or an exemption from such registration is
available. The undersigned (i) understands that such exemptions are limited and
that the Company is not under any obligation to effect any such registration and
(ii) has obtained advice of counsel as to the nature and conditions of such
exemptions, including information with respect to the applicability to the sale
of such securities of Rules 144 and 145(d) promulgated under the Securities Act.

    The undersigned hereby represents to and covenants with CEI and the Company
that the undersigned will not sell, assign or transfer any of the Company Common
Stock received by the undersigned in exchange for shares of NU Common Shares
pursuant to the NU Merger except (i) pursuant to an effective registration
statement under the Securities Act or (ii) in a transaction that, in the opinion
of counsel reasonably satisfactory to the Company or as described in a
"no-action" or interpretive letter from the Staff of the SEC, is not required to
be registered under the Securities Act.

    In the event of a sale or other disposition by the undersigned pursuant to
Rule 145, of Company Common Stock received by the undersigned in the NU Merger,
the undersigned will supply the Company with evidence of compliance with such
Rule, in the form of a letter in the form of Annex I hereto and the opinion of
counsel or no-action letter referred to above. The undersigned understands that
the Company may instruct its transfer agent to withhold the transfer of any
Company Common Stock disposed of by the undersigned, but that upon receipt of
such evidence of compliance the transfer agent shall effectuate the transfer of
the Company Common Stock sold as indicated in the letter.

    The undersigned acknowledges and agrees that (i) the Company Common Stock
issued to the undersigned will all be in certificated form and (ii) appropriate
legends will be placed on certificates representing Company Common Stock
received by the undersigned in the NU Merger or held by a transferee thereof,
which legends will be removed by delivery of substitute certificates upon
receipt of an opinion in form and substance reasonably satisfactory to the
Company from counsel reasonably satisfactory to the Company to the effect that
such legends are no longer required for purposes of the Securities Act.

    The undersigned acknowledges that (i) the undersigned has carefully read
this letter and understands the requirements hereof and the limitations imposed
upon the distribution, sale, transfer or other disposition of Company Common
Stock and (ii) the receipt by CEI and the Company of this letter is an
inducement to CEI's and the Company's consummation of the Mergers.

                                 Very truly yours,

Edison, Inc. ("THE COMPANY") described below in the space provided for that
purpose (the "SECURITIES"). The Securities were received by the undersigned in
connection with the merger of MERGER LLC with and into NU.

                          FORM OF CEI AFFILIATE LETTER

Dear Sirs:

    The undersigned refers to the Agreement and Plan of Merger dated as of
October 13, 1999, as amended and restated as of January 11, 2000 (the "MERGER
AGREEMENT"), among Consolidated Edison, Inc., a New York corporation ("CEI"),
Northeast Utilities, a Massachusetts business trust ("NU"), Consolidated
Edison, Inc., originally incorporated as CWB Holdings, Inc., a Delaware
corporation ("NEW CEI"), and N Acquisition LLC, a Massachusetts limited
liability company ("MERGER LLC"). Capitalized terms used but not defined in this
letter have the meanings given such terms in the Merger Agreement.

    The undersigned, a holder of shares of CEI Common Stock, is entitled to
receive in connection with the CEI Merger shares of Company Common Stock. The
undersigned acknowledges that the undersigned may be deemed an "affiliate" of
CEI within the meaning of Rule 145 ("RULE 145") promulgated under the Securities

such fact.

    If in fact the undersigned were an affiliate under the Securities Act, the
undersigned's ability to sell, assign or transfer the Company Common Stock
received by the undersigned in exchange for any shares of CEI Common Stock
pursuant to the CEI Merger may be restricted unless such transaction is
registered under the Securities Act or an exemption from such registration is
available. The undersigned (i) understands that such exemptions are limited and

Ladies and Gentlemen:

    In connection with the opinions to be delivered pursuant to Sections 6.02(c)
and 6.03(c) of the Agreement and Plan of Merger dated as of October 13, 1999, as
amended and restated as of January 11, 2000 (the "Merger Agreement"), among
Consolidated Edison, Inc., a New York corporation ("CEI"), Northeast Utilities,
a Massachusetts business trust ("NU"), Consolidated Edison, Inc., originally
incorporated as CWB Holdings, Inc., a Delaware corporation and a wholly owned
subsidiary of CEI (the "Company") and N Acquisition LLC, a Massachusetts limited
liability company ("Merger LLC"), 99% of which is owned by the Company and 1% of
which is owned by X Holding LLC, a Massachusetts limited liability company, 99%
of which is owned by the Company and 1% of which is owned by N Acquisition LLC,
and in connection with the filing with the Securities and Exchange Commission
(the "SEC") of the registration statement on Form S-4 (the "Registration
Statement"), which includes the proxy statement/prospectus of CEI and NU, each
as amended and supplemented through the date hereof, the undersigned certifies
and represents on behalf of CEI and as to CEI, after due inquiry and
investigation, as follows (any capitalized term used but not defined herein
having the meaning given to such term in the Merger Agreement):

    1. The Mergers will be consummated in accordance with the Merger Agreement
and as described in the Registration Statement. The facts relating to the
Mergers as described in the Registration Statement and the documents referenced
in the Registration Statement are, insofar as such facts relate to CEI, true,
correct and complete in all material respects.

    2. The formula set forth in the Merger Agreement pursuant to which each
issued and outstanding share of common stock, par value $.10 per share, of CEI
(the "CEI Common Stock") and each share of CEI Common Stock held by Consolidated
Edison Company of New York, Inc. will be converted into common shares, par value
$.01 per share, of the Company (the "Company Common Stock") is the result of
arm's length bargaining. The aggregate fair market value of the Company Common
Stock to be received by each holder of CEI Common Stock in the CEI Merger will
be approximately equal to the fair market value of CEI Common Stock surrendered
in exchange therefor.

    3. (i) Except to the extent specifically contemplated under the Merger
Agreement, neither CEI nor any corporation related to CEI has acquired or has
any present plan or intention to acquire any CEI Common Stock in contemplation
of the Mergers, or otherwise as part of a plan of which the Mergers are a part.

      (ii) For purposes of this representation letter, a corporation shall be
treated as related to CEI if such corporation is related to CEI within the
meaning of Treasury Regulation Section 1.368-1(e)(3).

    4. CEI has not made and does not have any present plan or intention to make
any distributions (other than dividends made in the ordinary course of business)
to holders of CEI Common Stock prior to, in contemplation of, or otherwise in
connection with, the Mergers.

    5. Except to the extent specifically contemplated under the Merger
Agreement, the Company, CEI and holders of CEI Common Stock will each pay their
respective expenses, if any, incurred in
<PAGE>
                                                                               2
connection with the CEI Merger. Except to the extent specifically contemplated
under the Merger Agreement, CEI has not agreed to assume, nor will it directly
or indirectly assume, any expense or other liability, whether fixed or
contingent, of any holder of CEI Common Stock. Further, no liabilities of any of
the holders of CEI Common Stock will be assumed by the Company, nor will any of
the CEI Common Stock acquired by the Company in connection with the CEI Merger
be subject to any liabilities.

    6. Any liabilities of CEI that will be assumed by the Company pursuant to
the Mergers, and any liabilities to which the assets of CEI that will be
transferred to the Company pursuant to the Mergers are subject, were incurred in
the ordinary course of business and are associated with the assets of CEI.

    7. At the CEI Effective Time, the value of the Company Common Stock issued
to the holders of CEI Common Stock in the CEI Merger will represent at least 50%
of the value of the total consideration issued to such holders in the CEI Merger
in exchange for their shares of CEI Common Stock.

    8. CEI is not an investment company as defined in
Section 368(a)(2)(F)(iii) and (iv) of the Internal Revenue Code of 1986, as
amended (the "Code"), Section 351(e)(1) of the Code or Treasury Regulation
Section 1.351-1(c)(1)(ii).

    9. CEI will not take, and to the best knowledge of the management of CEI
there is no present plan or intention by any holders of CEI Common Stock to
take, any position on any Federal, state or local income or franchise tax
return, or to take any other tax reporting position, that is inconsistent
(i) with the treatment of the Mergers as a transaction described in Section 351
of the Code or (ii) with the treatment of the CEI Merger as a reorganization
within the meaning of Section 368(a) of the Code, in each case unless otherwise
required by a "determination" (as defined in Section 1313(a)(1) of the Code) or
by applicable state or local tax law (and then only to the extent required by
such applicable state or local tax law).

    10. None of the compensation received by any stockholder-employee of CEI in
respect of periods ending at or prior to the CEI Effective Time represents
separate consideration for any of his or her CEI Common Stock. None of the
Company Common Stock that will be received by any stockholder-employee of CEI in
the CEI Merger represents separately bargained for consideration which is
allocable to any employment agreement or arrangement. The compensation paid to
any stockholder-employees will be for services actually rendered and will be
determined by bargaining at arm's-length.

    11. There is no intercorporate indebtedness existing between the Company and
CEI.

    12. CEI is not under the jurisdiction of a court in a Title 11 or similar
case within the meaning of Section 368(a)(3)(A) of the Code.

    13. No assets of CEI have been sold, transferred or otherwise disposed of
which would prevent the Company or the Company's "qualified group" of
corporations (as defined in Treasury Regulation Section 1.368-1(d)(4)(ii)) from
continuing the "historic business" of CEI or from using a significant portion of
the "historic business assets" of CEI in a business following the Mergers (as
such terms are defined in Treasury Regulation Section 1.368-1(d)).

    14. At the CEI Effective Time, the fair market value of the assets of CEI
transferred to the Company pursuant to the CEI Merger will exceed the sum of its
liabilities assumed by the Company pursuant to the CEI Merger, plus the amount
of liabilities, if any, to which such assets are subject.

    15. To the best knowledge of the management of CEI, there is no present plan
or intention on the part of the holders of CEI Common Stock to sell, exchange or
otherwise dispose of, or to enter into any contract or other arrangement with
respect to, any interest in the shares of Company Common Stock received in the
CEI Merger in exchange for such CEI Common Stock such that the former holders of
CEI Common Stock and the former holders of NU Common Shares, in the aggregate,
would not own (i) Company Common Stock having at least 80% of the total combined
voting power of all classes of Company stock entitled to vote and (ii) at least
80% of the total number of shares of each other class of Company stock.
<PAGE>
                                                                               3

    16. CEI will not retain any rights in the CEI assets transferred to the
Company pursuant to the CEI Merger.

    17. None of the stock of any CEI Subsidiary being transferred in the CEI
Merger is Section 306 stock within the meaning of Section 306(c) of the Code.

    18. To the best knowledge of the management of CEI and taking into account
any issuance of additional shares of Company Common Stock, any issuance of
Company Common Stock for services, the exercise of any Company stock rights,
options, warrants or subscriptions, any public offerings of Company stock, and
the sale, exchange, transfer by gift or other disposition of any Company Common
Stock received by holders of CEI Common Stock in the CEI Merger, the holders of
CEI Common Stock and NU Common Shares will collectively be in "control" of the
Company immediately after the Mergers. For purposes of this representation
letter, "control" shall mean the ownership of (i) stock possessing at least 80%
of the total combined voting power of all classes of Company stock entitled to
vote and (ii) at least 80% of the total number of shares of each other class of
Company stock.

    19. The Company Common Stock issued in the Mergers will constitute all of
the Company's outstanding stock immediately after the Mergers. Except as
specifically set forth in the Merger Agreement, the Company will not issue any
Company Common Stock in connection with the Mergers in consideration for
services rendered to or for the benefit of the Company or any of its affiliates,
or in consideration for the transfer of any property other than NU Common Shares
and the associated NU Rights or CEI assets.

    20. The NU Merger, the CEI Merger and the simultaneous exchange of NU Common
Shares and CEI Common Stock for Company Common Stock and cash are all part of a
single integrated transaction and no one part of the transaction will be carried
out without the entire transaction being consummated in its entirety. All
exchanges will occur on approximately the same date.

the Mergers, prior to the Effective Time, Merger LLC will have no material
assets or liabilities and will carry on no business.

    22. To the best knowledge of the management of CEI, no foreign person owns

Common Stock during the applicable period specified in

    23. To the best knowledge of the management of CEI, the Company will remain
in existence and hold the CEI assets transferred to it for use in its trade or
business.

    24. Throughout the period of time that the Yankee Merger Agreement was

nor CEI had any plan or intention to engage, directly or indirectly, in the
transactions contemplated by the Merger Agreement.

Agreement did not occur prior to [      ].

have the Company acquire for cash the NU Common Shares issued to them in the
acquisition of Yankee pursuant to the Yankee Merger Agreement.

    27. The Company's obligation under the Merger Agreement to acquire NU Common
Shares for cash was not undertaken at the request of Yankee or any Yankee
Shareholder.

    28. The signing of the Merger Agreement was not dependent upon the Yankee
Shareholders' approval of the acquisition of Yankee pursuant to the Yankee
Merger Agreement.

    29. The consummation of the transactions contemplated by the Merger
Agreement are not dependent on the closing of the acquisition of Yankee pursuant
to the Yankee Merger Agreement.

of NU and for other good and valid business purposes of NU.

described in the Registration Statement represent the entire understanding of NU
and Merger LLC with respect to the Mergers.

Ladies and Gentlemen:

    In connection with the opinions to be delivered pursuant to Sections 6.02(c)
and 6.03(c) of the Agreement and Plan of Merger dated as of October 13, 1999, as
amended and restated as of January 11, 2000 (the "Merger Agreement"), among
Consolidated Edison, Inc., a New York corporation ("CEI"), Northeast Utilities,
a Massachusetts business trust ("NU"), Consolidated Edison, Inc., originally
incorporated as CWB Holdings, Inc., a Delaware corporation and a wholly owned
subsidiary of CEI (the "Company") and N Acquisition LLC, a Massachusetts limited
liability company ("Merger LLC"), 99% of which is owned by the Company and 1% of
which is owned by X Holding LLC, a Massachusetts limited liability company, 99%
of which is owned by the Company and 1% of which is owned by N Acquisition LLC,
and in connection with the filing with the Securities and Exchange Commission
(the "SEC") of the registration statement on Form S-4 (the "Registration
Statement"), which includes the proxy statement/prospectus of CEI and NU, each
as amended and supplemented through the date hereof, the undersigned certifies
and represents on behalf of the Company and as to the Company, after due inquiry
and investigation, as follows (any capitalized term used but not defined herein
having the meaning given to such term in the Merger Agreement):

    1. The Mergers will be consummated in accordance with the Merger Agreement
and as described in the Registration Statement. The facts relating to the
Mergers as described in the Registration Statement and the documents referenced
in the Registration Statement are, insofar as such facts relate to the Company,
true, correct and complete in all material respects.

    2. The formulae set forth in the Merger Agreement pursuant to which each
issued and outstanding share of common stock, par value $.10 per share, of CEI
(the "CEI Common Stock") and each share of CEI Common Stock held by Consolidated
Edison Company of New York, Inc. will be converted into common shares, par value
$.01 per share, of the Company (the "Company Common Stock") and each issued and
outstanding common share of beneficial interest, par value $5.00 per share, of
NU (the "NU Common Shares"), together with the associated NU Rights, will be
converted into Company Common Stock or cash are the result of arm's length
bargaining. The aggregate fair market value of the Company Common Stock to be
received by holders of CEI Common Stock in the CEI Merger will be approximately
equal to the fair market value of the CEI Common Stock surrendered in exchange
therefor. The aggregate fair market value of the Company Common Stock and/or
cash to be received by holders of NU Common Shares and associated NU Rights in
the NU Merger will be approximately equal to the fair market value of the NU
Common Shares and associated NU Rights surrendered in exchange therefor.

    3. (i) The Company has no present plan or intention, following the Mergers,
to reacquire, or to cause any corporation that is related to the Company to
acquire, any Company Common Stock issued in the Mergers, except for repurchases
of Company Common Stock by the Company in connection with a repurchase program
meeting the requirements of Section 4.05(1)(b) of Revenue Procedure 96-30. No
corporation that is related to the Company has a plan or intention to purchase
any of the Company Common Stock issued in the Mergers.
<PAGE>
                                                                               2

        (ii) For purposes of this representation letter, a corporation shall be
treated as related to the Company if such corporation is related to the Company
within the meaning of Treasury Regulation Section 1.368-1(e)(3).

    4. The Company has not acquired, nor, except as a result of the CEI Merger
will it acquire, nor has it owned in the past five years, any CEI Common Stock.
The Company has not acquired, nor, except as a result of the NU Merger will it
acquire, nor has it owned in the past five years, any NU Common Shares.

    5. The Company has no present plan or intention to make any distributions
after the Mergers to holders of Company Common Stock (other than dividends made
in the ordinary course of business).

    6. At the CEI Effective Time, the value of the Company Common Stock to be
issued to holders of CEI Common Stock in the CEI Merger will represent at least
50% of the value of the total consideration to be issued to such holders in the
CEI Merger in exchange for their shares of CEI Common Stock. Further, no
liabilities of NU or any of the holders of NU Common Shares and no liabilities
of any of the holders of CEI Common Stock, whether fixed or contingent, incurred
or to be incurred, will be assumed by the Company, nor will any of the NU Common
Shares or CEI Common Stock acquired by the Company in connection with the
Mergers be subject to any such liabilities.

    7. Except to the extent specifically contemplated under the Merger
Agreement, CEI, NU, Merger LLC, the Company and holders of CEI Common Stock and
NU Common Shares will each pay their respective expenses, if any, incurred in
connection with the Mergers. Except with respect to Transfer Taxes, the Company
has not paid, directly or indirectly, nor has it agreed to assume any expense or
other liability, whether fixed or contingent, incurred or to be incurred by NU,
any holder of NU Common Shares or any holder of CEI Common Stock in connection
with or as part of the Mergers or any related transactions.

    8. Following the CEI Merger, the Company or the Company's "qualified group"
of corporations (as defined in Treasury Regulation Section 1.368-1(d)(4)(ii))
will continue the "historic business" of CEI or use a significant portion of
CEI's "historic business assets" in a business (as such terms are defined in
Treasury Regulation Section 1.368-1(d)). Following the NU Merger, the Company
will cause NU to continue its historic business or to use a significant portion
of its historic business assets in a trade or business.

    9. The Company is not an investment company as defined in
Section 368(a)(2)(F)(iii) and (iv) of the Code, Section 351(e)(1) of the Code or
Treasury Regulation Section 1.351-1(c)(1)(ii).

    10. The Company will not take any position on any Federal, state or local
income or franchise tax return, or take any other tax reporting position, that
is inconsistent (i) with the treatment of the Mergers as a transaction described
in Section 351 of the Code or (ii) with the treatment of the CEI Merger as a
reorganization within the meaning of Section 368(a) of the Code, in each case
unless otherwise required by a "determination" (as defined in
Section 1313(a)(1) of the Code) or by applicable state or local tax law (and
then only to the extent required by such applicable state or local tax law).

    11. None of the compensation received by any stockholder-employee of CEI in
respect of periods ending at or prior to the CEI Effective Time represents
separate consideration for any of his or her CEI Common Stock. None of the
compensation received by any stockholder-employee of NU in respect of periods
ending at or prior to the NU Effective Time represents separate consideration
for any of his or her NU Common Shares or associated NU Rights. None of the
Company Common Stock that will be received by any stockholder-employee of CEI or
NU in the Mergers represents separately bargained for consideration which is
allocable to any employment agreement or arrangement. The compensation paid to
any stockholder-employees will be for services actually rendered and will be
determined by bargaining at arm's-length.

    12. There is no intercorporate indebtedness existing between (i) the Company
and CEI or (ii) the Company and NU.

                                                                               3

    13. The Company is not under the jurisdiction of a court in a Title 11 or
similar case within the meaning of Section 368(a)(3)(A) of the Code.

    14. To the best knowledge of the management of the Company and taking into
account any issuance of additional shares of Company Common Stock, any issuance
of Company Common Stock for services, the exercise of any Company stock rights,
options, warrants or subscriptions, any public offerings of Company stock, and
the sale, exchange, transfer by gift or other disposition of any Company Common
Stock received in the Mergers, the holders of CEI Common Stock and NU Common
Shares will collectively be in "control" of the Company immediately after the
Mergers. For purposes of this representation letter, "control" shall mean the
ownership of (i) stock possessing at least 80% of the total combined voting
power of all classes of Company stock entitled to vote and (ii) at least 80% of
the total number of shares of each other class of Company stock.

    15. The Company has no present plan or intention to, or to cause any of its
affiliates to, (i) liquidate the Company or NU, (ii) merge (other than in
connection with the CEI Merger), liquidate or consolidate the Company or NU with
or into any other entity (including, without limitation, any affiliate),
(iii) sell, transfer, distribute or otherwise dispose of the NU Common Shares or
associated NU Rights or interests in any of its material affiliates or
(iv) sell, transfer, distribute or otherwise dispose of any of the material
assets of CEI, NU or their affiliates acquired in the Mergers (other than in the
ordinary course of business or transfers described in Section 368(a)(2)(C) of
the Code or Treasury Regulation Section 1.368-2(k) that also qualify as
transactions described in Section 351 of the Code).

    16. The Company Common Stock issued in the Mergers will constitute all of
the Company's outstanding stock immediately after the Mergers. Except as
specifically set forth in the Merger Agreement, the Company will not issue any
Company Common Stock in connection with the Mergers in consideration for
services rendered to or for the benefit of the Company or any of its affiliates,
or in consideration for the transfer of any property other than NU Common Shares
and the associated NU Rights or CEI assets.

    17. None of the holders of NU Common Shares will retain any rights in the NU
Common Shares or associated NU Rights transferred to the Company pursuant to the
NU Merger. CEI will not retain any rights in the CEI assets transferred to the
Company pursuant to the CEI Merger.

    18. The NU Merger, the CEI Merger and the simultaneous exchange of NU Common
Shares and CEI Common Stock for Company Common Stock and cash are all part of a
single integrated transaction and no one part of the transaction will be carried
out without the entire transaction being consummated in its entirety. All
exchanges will occur on approximately the same date.

    19. Except for the activities required to accomplish the actions to effect
the Mergers, prior to the Effective Time, Merger LLC will have no material
assets or liabilities and will carry on no business.

    20. To the best knowledge of the management of the Company, no foreign
person owns or has owned beneficially more than 5% of the total fair market
value of (i) the NU Common Shares or (ii) the CEI Common Stock, in each case,
during the applicable period specified in Section 897(c)(1)(A)(ii) of the Code.

    21. The Company will remain in existence and hold the NU Common Shares and
CEI assets transferred to it for use in its trade or business.

    22. Throughout the period of time that the Yankee Merger Agreement was
negotiated and at the time the Yankee Merger Agreement was signed, neither NU
nor CEI had any plan or intention to engage, directly or indirectly, in the
transactions contemplated by the Merger Agreement.

    23. Discussion concerning the transactions contemplated by the Merger
Agreement did not occur prior to [      ].

    24. To the best knowledge of the management of the Company, there is no plan
or intention on the part of the Yankee Shareholders to utilize the NU Merger to
have the Company acquire for cash

the NU Common Shares issued to them in the acquisition of Yankee pursuant to the

    25. The Company's obligation under the Merger Agreement to acquire NU Common

to the Yankee Merger Agreement.

<PAGE>
                                                                         ANNEX B

October 12, 1999

Board of Directors
Consolidated Edison, Inc.
4 Irving Place
New York, New York 10003

Ladies and Gentlemen:

    You have requested our opinion as to the fairness, from a financial point of
view, to the holders of shares of the common stock of Consolidated Edison, Inc.
(the "Company") of the Exchange Ratio (as defined below) in connection with the
Mergers (as defined below) contemplated by the Agreement and Plan of Merger (the
"Agreement") to be entered into among the Company, Northeast Utilities (the
"Subject Company"), CWB Holdings, Inc. ("Newco") and N Acquisition LLC ("Merger
LLC"), 99% of which is owned by Newco and 1% of which is owned by X Holding LLC,
99% of which is owned by Newco and 1% of which is owned by Merger LLC.

    As more specifically set forth in the Agreement, and subject to the terms
and conditions thereof, (i) the Company will merge with and into Newco (the
"Company Merger") and each issued and outstanding share of the common stock, par
value $.10 per share, of the Company (the "Company Common Stock"), other than
shares owned by the Company or Newco, which shall be canceled, shall be
converted into the right to receive one share of common stock, par value $.10
per share, of Newco (the "Newco Common Stock") and (ii) Merger LLC will merge
with and into the Subject Company (the "Subject Company Merger" and, together
with the Company Merger, the "Mergers") and each common share of beneficial
interest, par value $5.00 per share, of the Subject Company (the "Subject
Company Common Stock"), other than shares owned by the Subject Company or Newco,
which shall be canceled, shall be converted into the right to receive, at the
election of the holder of such share, either (x) an amount in cash equal to
$25.00 plus, if the closing of the Mergers shall not have occurred on or prior
to August 5, 2000, $.0034 per day for each day in the period from August 6, 2000
until the day that is one day prior to the closing of the Mergers (the "Per
Share Cash Amount"), or (y) a number of shares of Newco Common Stock equal to
the per share Cash Amount divided by the Market Price (as defined in the
Agreement) of Company Common Stock; provided, however, that if the Market Price
of Company Common Stock is less than $36, the denominator in such calculation
shall be $36 and if the Market Price of Company Common Stock is greater than
$46, the denominator in such calculation shall be $46. The Agreement provides
that 50% of the outstanding Subject Company Common Stock will be converted into
the right to receive Newco Common Stock and 50% of the outstanding Subject
Company Common Stock will be converted into the right to receive cash. The
holders of Subject Company Common Stock will have the right to receive an
additional $1.00 in value, by adjustment to the cash or stock received in the
Mergers or pursuant to nontransferable contingent value rights to be distributed
in the Mergers, if a definitive agreement is reached to sell the Subject
Company's interests in both of its operating Millstone nuclear facilities and
such agreement is approved by the Connecticut Department of Public Utility
Control, or such approval is recommended by its Utility Operations and
Management Unit, in each case on or prior to the later of December 31, 2000 and
the closing of the Mergers. As used herein, the term "Exchange Ratio" means the
conversion of shares of Company Common Stock into Newco Common Stock on a
one-for-one basis, taking into account the acquisition of the Subject Company
and the consideration paid in connection with the Subject Company Merger.

    In arriving at our opinion, we reviewed a draft of the Agreement, dated
October 12, 1999, and held discussions with certain senior officers, directors
and other representatives and advisors of the Company and certain senior
officers and other representatives and advisors of the Subject Company
concerning the businesses, operations and prospects of the Company and the
Subject Company. We examined certain publicly available business and financial
information relating to the Company and the Subject Company (including Yankee
Energy System, the acquisition of which by the Subject Company
<PAGE>
                                                                               2
is pending) as well as certain financial forecasts and other information and
data for the Company and the Subject Company which were provided to or otherwise
discussed with us by the managements of the Company and the Subject Company,
including information relating to certain strategic implications and operational
benefits anticipated to result from the Mergers. We reviewed and discussed with
senior officers of the Company and the Subject Company the financial terms of
the Mergers as set forth in the Agreement in relation to, among other things:
current and historical market prices and trading volumes of Company Common Stock
and Subject Company Common Stock (including, specifically, recent prices and
volumes); the historical and projected earnings and other operating data of the
Company and the Subject Company; and the capitalization and financial condition
of the Company and the Subject Company. We considered, to the extent publicly
available, the financial terms of certain other similar transactions recently
effected that we considered relevant in evaluating the Mergers and analyzed
certain financial, stock market and other publicly available information
relating to the businesses of other companies whose operations we considered
relevant in evaluating those of the Company and the Subject Company. We also
evaluated the pro forma financial impact of the Mergers on the Company. In
addition to the foregoing, we conducted such other analyses and examinations and
considered such other information and financial, economic and market criteria as
we deemed appropriate in arriving at our opinion.

    In rendering our opinion, we have assumed and relied, without independent
verification, upon the accuracy and completeness of all financial and other
information and data publicly available or furnished to or otherwise reviewed by
or discussed with us and have further relied upon the assurances of management
of the Company and the Subject Company that they are not aware of any facts that
would make any of such information inaccurate or misleading. With respect to
financial forecasts and other information and data provided to or otherwise
reviewed by or discussed with us, we have been advised by the managements of the
Company and the Subject Company that such forecasts and other information and
data were reasonably prepared on bases reflecting the best currently available
estimates and judgments of the respective managements of the Company and the
Subject Company as to the future financial performance of the Company and the
Subject Company and the strategic implications and operational benefits
anticipated to result from the Mergers. We express no view with respect to such
forecasts and other information and data or the assumptions on which they were
based. We have assumed, with your consent, that the Mergers will be treated as
tax-free for federal income tax purposes. We have not made or been provided with
an independent evaluation or appraisal of the assets or liabilities (contingent
or otherwise) of the Company or the Subject Company nor have we made any
physical inspection of the properties or assets of the Company or the Subject
Company. Representatives of the Company have advised us, and we have assumed,
that the final terms of the Agreement will not vary materially from those set
forth in the draft reviewed by us. We have further assumed that the Mergers will
be consummated in accordance with the terms of the Agreement, without waiver of
any of the conditions precedent to the Mergers contained in the Agreement.

    Our opinion, as set forth herein, relates to the relative values of the
Company and the Subject Company. We are not expressing any opinion as to what
the value of the Newco Common Stock actually will be when issued in the Mergers
or the price at which the Newco Common Stock will trade subsequent to the
Mergers. We were not requested to consider, and our opinion does not address,
the relative merits of the Mergers as compared to any alternative business
strategies that might exist for the Company or the effect of any other
transaction in which the Company might engage. Our opinion necessarily is based
upon information available to us and financial, stock market and other
conditions and circumstances existing and disclosed to us as of the date hereof.

    Salomon Smith Barney Inc. Is acting as financial advisor to the Company in
connection with the Mergers and will receive a fee for our services, a portion
of which is payable upon the execution of the Agreement, another portion of
which is payable upon approval of the Mergers by the holders of Company Common
Stock and Subject Company Common Stock and the remainder of which is contingent
upon consummation of the Mergers. We have in the past provided investment
banking services to the Company and the Subject Company unrelated to the
Mergers, for which we have received compensation. In the ordinary course of our
business, we and our affiliates may actively trade

                                                                               3
or hold the securities of the Company and the Subject Company for our own
account or for the account of our customers and, accordingly, may at any time
hold a long or short position in such securities. Salomon Smith Barney Inc. and
its affiliates (including Citigroup Inc. and its affiliates) may maintain
relationships with the Company and the Subject Company and their respective
affiliates.

    Our advisory services and the opinion expressed herein are provided for the
information of the Board of Directors of the Company in its evaluation of the
Mergers and our opinion is not intended to be and does not constitute a
recommendation of the Mergers to the Company or a recommendation to any
stockholder as to how such stockholder should vote on any matters relating to
the proposed Mergers.

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

                                          Very truly yours,

    We understand that Northeast Utilities (the "Company"), Consolidated
Edison, Inc. ("ConEd"), Consolidated Edison, Inc., originally incorporated as
CWB Holdings, Inc., a Delaware corporation and a wholly owned subsidiary of
ConEd ("CWB Holdings"), and N Acquisition LLC, a Massachusetts limited liability
company ("Merger LLC"), 99% of which is owned by CWB Holdings and 1% of which is
owned by X Holding LLC, a Massachusetts limited liability company, 99% of which
is owned by CWB Holdings and 1% of which is owned by Merger LLC, have entered
into an Agreement and Plan of Merger dated October 12, 1999, amended and
restated as of January 11, 2000 (the "Merger Agreement"), which provides, among
other things, for the simultaneous mergers of ConEd with and into Holding Sub
and CWB Holdings and Merger LLC with and into the Company (collectively, the
"Mergers"). Pursuant to the Mergers, the Company will become a wholly owned
subsidiary of CWB Holdings and each outstanding common share of beneficial
interest, par value $5.00 per share (collectively, the "NU Common Shares") of
the Company and associated rights to purchase NU Common Shares, other than
shares held in treasury or held by ConEd, will be converted into the right to
receive (i) a certain number of shares of common stock, par value $0.10 per
share ("CWB Holdings Common Stock"), of CWB Holdings determined pursuant to a
certain formula set forth in the Merger Agreement (ii) $25.00 in cash, subject
to adjustment in certain circumstances or (iii) a combination thereof
(collectively, the "Consideration"), each as determined pursuant to the terms
and conditions of the Merger Agreement. The value of the Consideration is
subject to adjustment based upon the timing of the consummation of the Mergers
and certain asset dispositions. The terms and conditions of the Mergers are more
fully set forth in the Merger Agreement.

    You have asked for our opinion as to whether the Consideration to be
received by the holders of NU Common Shares pursuant to the Merger Agreement is
fair from a financial point of view to such holders.

    For purposes of the opinion set forth herein, we have:

    (i) reviewed certain publicly available financial statements and other
        information of the Company and ConEd;

    (ii) reviewed certain internal financial statements and other financial and
         operating data concerning the Company and ConEd prepared by the
         management of the Company and ConEd, respectively;

   (iii) reviewed certain financial projections prepared by the management of
         the Company and ConEd;

    (iv) discussed the past and current operations and financial condition and
         the prospects of the Company and ConEd, including the strategic
         rationale for the Mergers and information relating to certain
         strategic, financial and operational benefits anticipated from the
         Mergers with senior executives of the Company and ConEd, respectively;

    (v) reviewed the pro forma impact of the Mergers on ConEd's earnings per
        share;

    (vi) reviewed the reported prices and trading activity for the NU Common
         Shares and the common stock of ConEd;

   (vii) analyzed the effects on the Company of the acquisition of Yankee Energy
         System, Inc., by the Company;

  (viii) analyzed the effects on the Company of the potential divestiture of two
         of its nuclear powered generation units, Millstone Units 2 and 3;

    (ix) compared the financial performance of the Company and ConEd and the
         prices and trading activity of the NU Common Shares and the common
         stock of ConEd with that of certain other comparable publicly-traded
         companies and their securities;

    (x) reviewed the financial terms, to the extent publicly available, of
        certain comparable acquisition transactions;

    (xi) participated in discussions and negotiations among representatives of
         the Company and ConEd and their financial and legal advisors;

   (xii) reviewed the draft Merger Agreement and certain related documents; and

  (xiii) performed such other analyses and considered such factors as we have
         deemed appropriate.

    We have assumed and relied upon without independent verification the
accuracy and completeness of the information reviewed by us for the purposes of
this opinion. With respect to the financial projections, and information
relating to certain strategic, financial and operational benefits anticipated
from the Mergers, we have assumed that they have been reasonably prepared on
bases reflecting the best currently available estimates and judgments of the
future financial performance of the Company and ConEd. In addition, we have
assumed that the Mergers will be consummated in accordance with the terms set
forth in the Merger Agreement, including, among other things, that the Mergers
will be treated as a tax-free reorganization and/or exchange, each pursuant to
the Internal Revenue Code of 1986. We have not made any independent valuation or
appraisal of the assets or liabilities of the Company, nor have we been
furnished with any such appraisals. Our opinion is necessarily based on
financial, economic, market and other conditions as in effect on, and the
information made available to us as of, the date hereof.

    We note that we are not legal or regulatory experts and have relied upon,
without independent verification, the assessment of the Company's legal and
regulatory advisors with respect to the legal and regulatory matters related to
the Mergers.

    In arriving at our opinion, we were not authorized to solicit, and did not
solicit, interest from any party with respect to an acquisition, business
combination or other extraordinary transaction involving the Company.

    We have acted as financial advisor to the Board of Trustees of the Company
in connection with this transaction and will receive a fee for our services. In
the past, Morgan Stanley & Co. Incorporated and its affiliates have provided
financial advisory and financing services for the Company and ConEd and have
received fees for the rendering of these services.

    It is understood that this letter is for the information of the Board of
Trustees of the Company, except that this opinion may be included in its
entirety in any filing made by the Company in respect of the transaction with
the Securities and Exchange Commission. In addition, this opinion does not in
any manner address the prices at which the CWB Holdings Common Stock will trade
following consummation of the Mergers and Morgan Stanley expresses no opinion or
recommendation as to how the shareholders of the Company should vote at the
shareholders meeting held in connection with the Mergers.

    Based upon and subject to the foregoing, we are of the opinion on the date
hereof that the Consideration to be received by the holders of NU Common Shares

holders.

The Board of Trustees
Northeast Utilities
174 Brush Hill Avenue
West Springfield, MA 01090

Dear Members of the Board:

    We understand that Northeast Utilities, a Massachusetts business trust
("NU") and Consolidated Edison, Inc., a New York Corporation ("Con Ed"), have
determined to engage in a business combination transaction, the terms and
conditions of which are set forth in the Agreement and Plan of Merger, dated as
of October 13, 1999, amended and restated as of January 11, 2000 (the
"Agreement"). The Agreement provides for, among other things, the merger (the
"CEI Merger") of Con Ed with and into Consolidated Edison, Inc., a Delaware
corporation originally incorporated as CWB Holdings, Inc., a Delaware
corporation, 60% of whose outstanding capital stock is to be owned by Con Ed and
40% of whose outstanding capital stock is to be owned by NU (the "Company"),
whereby each issued and outstanding share of Con Ed common stock, par value
$0.10 per share ("Con Ed Common Stock") (other than Dissenting Shares and shares
canceled pursuant to Section 2.01(a) of the Agreement), shall be converted into
the right to receive one share of common stock, par value $0.10 of the Company
(the "Company Common Stock"). The Agreement also provides for the merger (the
"NU Merger") of N Acquisition LLC, a Massachusetts limited liability company,
99% of which is owned by the Company and 1% of which is owned by N Acquisition
Holding Corp., a Delaware corporation and wholly-owned subsidiary of the
Company, with and into NU. The Agreement provides that at the effective time of
the NU Merger, each common share of beneficial interest, par value $5.00 per
share, of NU ("NU Common Shares") (other than Dissenting Shares and shares
canceled pursuant to Section 2.01(b) of the Agreement), shall be converted into
either (i) the right to receive $25.00 in cash (as such amount may be adjusted
in accordance with Section 2.01(b) and/or Section 2.05 of the Agreement, the
"Cash Consideration"), or (ii) the right to receive a number of validly issued,
fully paid and nonassessable shares of Company Common Stock, equal to the Cash
Consideration divided by the average (but in no event less than $36.00 or more
than $46.00) of the volume weighted averages of the trading prices of the shares
of Con Ed Common Stock on the NYSE for the 20 trading days randomly selected by
lot from the 40 consecutive NYSE trading days ending with the fifth trading day
prior to the Closing Date (as such number of shares may be adjusted in
accordance with Section 2.04(e) of the Agreement, the "Stock Consideration").
Notwithstanding the foregoing and subject to Section 2.03 of the Agreement, the
number of NU Common Shares to be converted into the right to receive (i) Stock
Consideration at the Effective Time shall not exceed 50% of the NU Outstanding
Shares and (ii) Cash Consideration at the Effective Time shall not exceed 50% of
the NU Outstanding Shares. The terms and conditions of the Mergers are set forth
in more detail in the Agreement. Capitalized terms used herein without
definition have the respective meanings assigned to such terms in the Agreement.

    We have been requested by NU to render our opinion with respect to the
fairness, from a financial point of view, to holders of NU Common Stock of the
Cash Consideration and Stock Consideration (collectively the "Merger
Consideration") to be offered pursuant to the Agreement.

    In arriving at our opinion, we have, among other things:

    (1) Reviewed the Annual Reports, Forms 10-K and the related financial
       information for the three-year period ended December 31, 1998, and the
       Forms 10-Q and the related unaudited financial information for the
       periods ended March 31, 1999, June 30, 1999 and September 30, 1999 for
       NU;

    (2) Reviewed the Annual Reports, Forms 10-K and the related financial
       information for the three-year period ended December 31, 1998 and the
       Forms 10-Q and the related unaudited

       financial information for the periods ended March 31, 1999, June 30, 1999
       and September 30, 1999 for Con Ed;

    (3) Reviewed certain other filings with the Securities and Exchange
       Commission and other regulatory authorities made by NU and Con Ed during
       the last three years, including proxy statements, FERC Forms 1 and 2,
       Forms 8-K and registration statements;

    (4) Reviewed certain internal information, including financial forecasts,
       relating to the business, earnings, capital expenditures, cash flow,
       assets and prospects of NU and Con Ed furnished to us by NU and Con Ed;

    (5) Conducted discussions with members of senior management of NU and Con Ed
       concerning their respective businesses, regulatory environments,
       prospects, strategic objectives and possible operating and administrative
       synergies and other benefits which might be realized for the benefit of
       the combined company following the Mergers;

    (6) Reviewed the historical market prices and trading activity for shares of
       NU Common Stock and Con Ed Common Stock and compared them with those of
       certain publicly traded companies which we deemed to be relevant;

    (7) Compared the results of operations of NU and Con Ed with those of
       certain companies which we deemed to be relevant;

    (8) Compared the proposed financial terms of the Mergers with the financial
       terms of certain utility industry business combinations which we deemed
       to be relevant and adjusted these terms to reflect changes in the market
       environment as we deemed to be appropriate;

    (9) Analyzed the valuation of shares of NU Common Stock and Con Ed Common
       Stock using various valuation methodologies which we deemed to be
       appropriate;

    (10) Considered the market value of shares of Northeast Optic Network, Inc.
       common stock using various methodologies which we deemed to be
       appropriate;

    (11) Considered the pro forma capitalization, earnings and cash flow of the
       combined company;

    (12) Compared the pro forma earnings per share and dividends per share of
       the combined company with each of the corresponding current and projected
       values for NU and Con Ed on a stand-alone basis;

    (13) Reviewed the Agreement;

    (14) Reviewed the Proxy/Registration Statement of NU and Con Ed dated the
       date hereof; and

    (15) Reviewed such other studies, conducted such other analyses, considered
       such other financial, economic and market criteria, performed such other
       investigations and taken into account such other matters as we deemed
       necessary or appropriate for purposes of this opinion.

    In rendering our opinion, we have relied, without independent verification,
upon the accuracy and completeness of all financial and other information
publicly available or otherwise furnished or made available to us by NU and Con
Ed and have further relied upon the assurances of management of NU and Con Ed
that they are not aware of any facts that would make such information inaccurate
or misleading. With respect to the financial projections of NU and Con Ed, we
have relied upon the assurances of management of NU and Con Ed that such
projections have been reasonably prepared and reflect the best currently
available estimates and judgments of the respective managements of NU and Con Ed
as to the future financial performance of NU and Con Ed, as the case may be, and
as to the projected outcomes of legal, regulatory and other contingencies. In
arriving at our opinion, we have not made or been provided with an independent
evaluation or appraisal of the assets or liabilities

(contingent or otherwise) of NU or Con Ed, nor have we made any physical
inspection of the properties or assets of NU or Con Ed. We have assumed that the
Mergers will constitute a transaction described in Section 351 of the Internal
Revenue Code of 1986, as amended (the "Code"), that the CEI Merger will
constitute a transaction described in Section 368(a) of the Code and that
holders of NU Common Stock and Con Ed Common Stock who exchange their shares
solely for the stock of the combined company will recognize no gain or loss for
federal income tax purposes as a result of the consummation of the Mergers. We
have also assumed that the combination will be accounted for by the purchase
method of accounting. Our opinion herein is necessarily based upon financial,
stock market and other conditions and circumstances existing and disclosed to us
as of the date thereof. Although we evaluated the fairness of the Merger
Consideration, from a financial point of view, to the holders of NU Common
Stock, the specific terms thereof were determined by NU and Con Ed through
arm's-length negotiations.

    The SG Barr Devlin division of SG Cowen Securities Corporation ("SG Barr
Devlin") has acted as financial advisor to NU in connection with the Mergers and
will receive certain fees for our services. In addition, we have in the past
rendered certain investment banking and financial advisory services to NU for
which we received customary compensation.

    Our advisory services and the opinion expressed herein are for the
information of NU's Board of Trustees in evaluating the Mergers. Except for its
publication in the Proxy/Registration Statement which will be distributed to
holders of NU Common Stock and Con Ed Common Stock in connection with approval
of the Mergers, our opinion may not be published or otherwise used or referred
to without our prior written consent. This opinion is not intended to be, and
does not constitute, a recommendation to any stockholder as to how such
stockholder should act with respect to the Mergers. This opinion is directed to
the fairness, from a financial point of view, to the holders of NU Common Stock
of the Merger Consideration taken as a whole, and not to the fairness of the
Cash Consideration, the Stock Consideration or the combination thereof to be
received by any particular holder of NU Common Stock, as to which we are
expressing no opinion.

    Based upon and subject to the foregoing, our experience as investment
bankers and other factors we deem relevant, we are of the opinion that, as of
the date hereof, the Merger Consideration to be offered pursuant to the
Agreement is fair, from a financial point of view, to the holders of NU Common
Stock.

                                          Very truly yours,
                                          /s/ SG Barr Devlin
