                                                                 , 1999
 
Dear Shareholder:
 
    Enclosed is important information relating to the following two items:
 
    (i) an offer by New York State Electric & Gas Corporation (the "Company") to
    purchase all of the outstanding shares of certain series of its serial
    preferred stock; and
 
    (ii) a companion proposal of the Company to increase the amount of unsecured
    indebtedness the Company may issue.
 
    We would greatly appreciate your giving prompt attention to the enclosed
material which you are urged to read in its entirety.
 
    The Company is offering to purchase all of the outstanding shares of the
series of its serial preferred stock listed on the front cover page of the
enclosed Offer to Purchase and Consent Statement. NONE OF THE COMPANY, ITS BOARD
OF DIRECTORS, NOR ANY OF ITS OFFICERS MAKES ANY RECOMMENDATION TO ANY
SHAREHOLDER AS TO WHETHER TO TENDER SHARES. EACH SHAREHOLDER MUST MAKE HIS OR
HER OWN DECISION AS TO WHETHER TO TENDER SHARES AND, IF SO, HOW MANY SHARES TO
TENDER.
 
    The Company's Restated Certificate of Incorporation, as amended, currently
restricts the ability of the Company to issue unsecured indebtedness without the
approval of the serial preferred shareholders. This restriction limits the
Company's flexibility in planning, financing and refinancing its business
activities. As competition has intensified in the utility industry, financial
flexibility and financial cost structure has become increasingly important for
the success of the Company. The proposal, as set forth and explained in the
enclosed material, would allow the Company to issue $         of unsecured
indebtedness in excess of unsecured indebtedness presently authorized, permitted
or previously consented to. We believe that approval of the proposal will play
an important role in increasing the financial flexibility and improving the
financial cost structure of the Company.
 
    You must grant your consent to the proposal in order to tender shares. The
Company's offer is conditioned upon, among other things, the proposal being
approved by the necessary votes of the serial preferred shareholders.
 
    If you grant your consent to the proposal and do not tender your shares and
the proposal is approved by the serial preferred shareholders, you will be
entitled to receive a special cash payment in an amount equal to $   for each
share with respect to which your consent is granted and not tendered. If you
tender your shares, and the shares are accepted for payment, you will receive
the applicable purchase price per share but will not be entitled to the special
cash payment. Instructions for tendering your shares and information pertaining
to the special cash payment is included in the enclosed material.
 
    The record date for determining serial preferred shareholders entitled to
grant a consent with respect to the consent solicitation is          , 1999. It
is important that you grant your consent to the proposal, regardless of the
number of shares you own. You are requested to return your consent, which is
included within the accompanying Letter of Transmittal and Consent, by
         , 1999.
 
    YOUR BOARD OF DIRECTORS RECOMMENDS THAT YOU GRANT YOUR CONSENT TO THE
PROPOSAL.
 
    If you have any questions regarding the consent solicitation or the
Company's offer to purchase shares, please call Salomon Smith Barney, the Dealer
Manager, at (800) 558-3745, Georgeson & Company, Inc., the Information Agent, at
(800) 223-2064, or your broker, dealer, commercial bank or trust company.
 
    Thank you for your continued interest in the Company.
 
                                          Sincerely,
 
                                          Sherwood J. Rafferty
                                          Senior Vice President and

    A Preferred Shareholder whose Shares are held by a broker, dealer,

commercial bank, trust company or nominee if he or she desires to tender, or to
consent to the Proposal without tendering, Shares. Any Preferred Shareholder

and consent to the Proposal with respect to such Shares, or to consent to the
Proposal without tendering Shares, must complete and sign the applicable Letter

Shares, deliver the certificates for such Shares to the Depositary, along with
the applicable Letter of Transmittal and Consent, or tender such Shares pursuant
to the procedure for book-entry transfer set forth herein on or prior to the
Expiration Date. Although tenders of Shares via book-entry transfer will be

completed Letter of Transmittal and Consent.
 
    Preferred Shareholders who become holders of record of Shares after the

their tender an irrevocable proxy from the holder of record of such Shares as of

under "Terms of the Offer--Procedure for Tendering Shares."
 
    EACH SERIES OF PREFERRED HAS ITS OWN LETTER OF TRANSMITTAL AND CONSENT.

TRANSMITTAL AND CONSENT HAVE BEEN COLOR-CODED AS FOLLOWS:

                                           the Company the flexibility to obtain financing
                                           on terms more advantageous to the Company than
                                           would otherwise be the case. In addition, the
                                           Offer gives Preferred Shareholders the
                                           opportunity to sell their Shares at a price
                                           which the Company believes to be a premium to

                                           the Proposal but not tender Shares pursuant to

                                           applicable Letter of Transmittal and Consent
                                           with respect to the granting of the consent, in
                                           accordance with the instructions in the

                                           but should not send certificates or effect a
                                           book-entry transfer of their Shares. Preferred
                                           Shareholders who wish to tender their Shares
                                           pursuant to the Offer must grant their consent
                                           by completing the applicable Letter of
                                           Transmittal and Consent. The same Letter of
                                           Transmittal and Consent may not be used to
                                           tender Shares and to grant consent with respect
                                           to Shares which are not being tendered. A
                                           Preferred Shareholder tendering a portion of his
                                           or her Shares and granting a consent with

                                           Transmittal and Consent, one with respect to the

                                           are not tendered. See "Proposal and Consent

                                           effective, provided that a written, dated
                                           revocation which clearly identifies the consent
                                           being revoked is executed and delivered to the
                                           Depositary at the address set forth on the back
                                           cover of this document. A revocation may be in

                                           holder as of the Record Date as long as it
                                           clearly states that the consent previously given
                                           is no longer effective.
 
Solicitation Fee.........................  If the Proposal is approved, the Company will

NUMBER OF SHARES; PURCHASE PRICES
 
    Upon the terms and subject to the conditions described herein and in the

properly withdrawn in accordance with "Terms of the Offer-- Withdrawal Rights")
at the purchase price per Share listed below, net to the seller in cash:
 
                       $      per share for the 3.75% Series
                       $      per share for the 4 1/2% Series
                       $      per share for the 4.40% Series
                       $      per share for the 4.15% (1954) Series
                       $      per share for the 4.15% Series

the 4.40% Series; 35,200 shares of the 4.15% (1954) Series; and 14,000 shares of
the 4.15% Series.
 
    The Offer is conditioned upon, among other things, the approval of the
Proposal by holders of at least a majority of the votes of shares of the
Outstanding Serial Preferred Stock entitled to be cast, considered together as
one class. The Offer is subject to certain other conditions. The Offer for any
one Series of Preferred is not conditioned upon any minimum number of shares of
such Series of Preferred being tendered and is independent of the Offer for any
other Series of Preferred. See "Terms of the Offer-- Conditions of the Offer."
 
    The Offer is being sent to all persons in whose names Shares are registered
on the books of the Company as of the close of business on                   ,
1999 as well as to all persons in whose names Shares are registered on the books
of the Company as of the Record Date. No record date is fixed for determining
which persons are permitted to tender Shares. However, only the holders of
record as of the Record Date, or Preferred Shareholders who acquire an
irrevocable proxy from such record holders, are permitted to grant their consent
to the Proposal and, accordingly, only such Preferred Shareholders may validly
tender Shares pursuant to the Offer.
 
    NO ALTERNATIVE, CONDITIONAL OR CONTINGENT TENDERS WILL BE ACCEPTED AND NO
TENDERS WILL BE ACCEPTED IN RESPECT OF SHARES FOR WHICH A CONSENT TO THE
PROPOSAL HAS NOT BEEN GRANTED. SUCH CONSENT IS GRANTED BY PROPERLY COMPLETING
THE FORM OF CONSENT THAT IS A PART OF THE APPLICABLE LETTER OF TRANSMITTAL AND
CONSENT.
 
EXPIRATION DATE; EXTENSION OF TENDER PERIOD
 
    With respect to each Series of Preferred, the Expiration Date for the Offer
is the later of 12:00 midnight, New York City time, on                   , 1999,
or the latest time and date to which the Offer with respect to such Series of
Preferred is extended.
 
    The Company expressly reserves the right, in its sole discretion, and at any
time and/or from time to time, to extend the period of time during which the
Offer for any Series of Preferred is open by giving oral or written notice of
such extension to the Depositary and by making a public announcement thereof,
without extending the period of time during which the Offer for any other Series
of Preferred is open. During any such extension, all Shares of the subject
Series of Preferred previously tendered will remain subject to the Offer, except
to the extent that such Shares may be withdrawn as set forth in "Terms of the
Offer--Withdrawal Rights." There is no assurance whatsoever that the Company
will exercise its right to extend the Offer for any Series of Preferred. The
Company may decide, in its sole discretion, to
 
                                       6
<PAGE>
(i) decrease the number of Shares of any Series of Preferred being sought, (ii)
increase or decrease the consideration offered in the Offer to holders of such
Series of Preferred or (iii) increase or decrease the Soliciting Dealers' fees.
If, at the time that notice of such increase or decrease is first published,
sent or given to holders of such Series of Preferred in the manner specified
herein and the Offer for such Series of Preferred is scheduled to expire at any
time earlier than the tenth business day from the date that such notice is first
published, sent or given, then such Offer will be extended until at least the
expiration of such ten business day period. The Company may be required to
extend the Offer if certain other material changes are made. See "Terms of the
Offer--Termination; Amendments." For purposes of the Offer, a "business day"
means any day other than a Saturday, Sunday or federal holiday and consists of
the time period from 12:01 a.m. through 12:00 midnight, New York City time.
 
PROCEDURE FOR TENDERING SHARES
 
    TENDERING SHARES.  To validly tender Shares pursuant to the Offer, Preferred
Shareholders must either:
 
        (a) send to the Depositary, or arrange for the Depositary to receive,
    prior to the Expiration Date (at one of its addresses set forth on the back
    cover of this document), a properly completed and duly executed Letter of
    Transmittal and Consent together with any required signature guarantees and
    any other documents required by the Letter of Transmittal and Consent, and
    either (i) send to the Depositary, or arrange for the Depositary to receive,
    at one of such addresses, certificates for the Shares to be tendered or (ii)
    effect delivery of such Shares pursuant to the procedures for book-entry
    transfer described herein (in which case, a confirmation of such delivery
    must also be received by the Depositary); or
 
        (b) comply with the guaranteed delivery procedure described under
    "Guaranteed Delivery Procedure" below.
 
    A Preferred Shareholder who is the beneficial owner of Shares which are held
by a broker, dealer, commercial bank, trust company or nominee must contact such
broker, dealer, commercial bank, trust company or nominee to either (i) arrange
for the record transfer of Shares to such Preferred Shareholder prior to
tendering or (ii) direct such Shares be properly tendered (including granting a
consent in respect thereof) on behalf of such Preferred Shareholder.
 
    In tendering, please use the applicable Letter of Transmittal and Consent:

</TABLE>
 
    The same Letter of Transmittal and Consent may not be used to tender Shares
and to grant consent with respect to Shares which are not being tendered. A
Preferred Shareholder tendering a portion of his or her Shares and granting a
consent with respect to other Shares without tendering such Shares must submit
two separate Letters of Transmittal and Consent, one with respect to the
tendered Shares and one with respect to the Shares for which a consent is
granted but which are not tendered.
 
    SINCE A CONSENT IS NECESSARY IN ORDER TO VALIDLY TENDER SHARES PURSUANT TO
THE OFFER AND ONLY PREFERRED SHAREHOLDERS OF RECORD AS OF THE RECORD DATE ARE
ENTITLED TO GRANT CONSENTS, PREFERRED SHAREHOLDERS WHO BECOME HOLDERS OF RECORD
OF SHARES AFTER THE RECORD DATE AND WHO WISH TO TENDER SUCH SHARES MUST OBTAIN
AND SUBMIT WITH THEIR TENDER AN
 
                                       7
<PAGE>
IRREVOCABLE PROXY FROM THE HOLDER OF RECORD OF SUCH SHARES AS OF THE RECORD DATE
IN ORDER TO GRANT THEIR CONSENT TO THE PROPOSAL.
 
    The NYSE, the National Association of Securities Dealers, Inc. (the "NASD")
and DTC have issued notices, informing their members and participants that the
Shares will trade "with proxy" and that settlement of all trades occurring after
the Record Date should include an irrevocable proxy from the holder of record of
such Shares as of the Record Date.
 
    A tender of Shares made pursuant to any method of delivery set forth herein
or in the applicable Letter of Transmittal and Consent in accordance with the
terms hereof and such Letter of Transmittal and Consent will constitute a
binding agreement between the tendering holder and the Company upon the terms
and subject to the conditions of the Offer.
 
    The Depositary will establish an account with respect to the Shares at DTC
(the "Book-Entry Transfer Facility") for purposes of the Offer within two
business days after the date hereof, and any financial institution that is a
participant in the system of the Book-Entry Transfer Facility may make delivery
of Shares by causing the transfer of such Shares into the Depositary's account
in accordance with the procedures of DTC's ATOP system. ALL TENDERS OF SHARES
VIA DTC'S ATOP SYSTEM MUST BE ACCOMPANIED BY A PROPERLY COMPLETED AND DULY
EXECUTED LETTER OF TRANSMITTAL AND CONSENT (TOGETHER WITH ANY OTHER REQUIRED
DOCUMENTS) THAT MUST BE RECEIVED BY THE DEPOSITARY PRIOR TO THE EXPIRATION DATE.
Delivery of such Letter of Transmittal and Consent and any other required
documents other than to the Depositary will not constitute a valid tender.
 
    If Shares are registered in the name of a person other than the signatory on
the applicable Letter of Transmittal and Consent, or if not all Shares
represented by a certificate are tendered in the Offer and the unpurchased
Shares are to be issued to a person other than the registered holder(s), the
certificates must be endorsed or accompanied by appropriate stock powers, in
either case signed exactly as the name or names of the registered holder(s)
appear on the Shares with the signature(s) on the Shares or stock powers
guaranteed as described below. See Instructions 4, 6 and 7 to the Letter of
Transmittal and Consent.
 
    THE METHOD OF DELIVERY OF SHARES AND ALL OTHER REQUIRED DOCUMENTS IS AT THE
OPTION AND RISK OF THE PREFERRED SHAREHOLDER. IF DELIVERY IS BY MAIL, REGISTERED
MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS RECOMMENDED. BECAUSE IT
IS THE TIME OF RECEIPT, NOT THE TIME OF MAILING, WHICH DETERMINES WHETHER A
TENDER HAS BEEN MADE PRIOR TO THE EXPIRATION DATE, SUFFICIENT TIME SHOULD BE
ALLOWED TO ASSURE TIMELY DELIVERY.
 
    All questions as to the form of documents and the validity, eligibility
(including the time of receipt) and acceptance for payment of any tender of
Shares will be determined by the Company in its sole discretion, and its
determination will be final and binding. The Company reserves the absolute right
to reject any and all tenders of Shares that (i) it determines are not in proper
form or (ii) the acceptance for payment of or payment for which may, in the
opinion of the Company, be unlawful. The Company also reserves the absolute
right to waive any defect or irregularity in any tender of Shares. None of the
Company, the Dealer Manager, the Depositary, the Information Agent nor any other
person will be under any duty to give notice of any defect or irregularity in
tenders, nor shall any of them incur any liability for failure to give any such
notice.
 
    FOR FURTHER INFORMATION IN TENDERING SHARES, CALL THE INFORMATION AGENT OR
THE DEALER MANAGER OR CONSULT YOUR BROKER FOR ASSISTANCE.
 
    SIGNATURE GUARANTEES.  In general, all signatures on a Letter of Transmittal
and Consent must be guaranteed by a firm that is a member of a registered
national securities exchange or the NASD, or by a commercial bank or trust
company having an office or correspondent in the United States that is a
participant in an approved Signature Guarantee Medallion Program (each of the
foregoing being referred
 
                                       8
<PAGE>
to as an "Eligible Institution"). However, signatures on a Letter of Transmittal
and Consent need not be guaranteed if (a) the Letter of Transmittal and Consent
is signed by the registered owner of the Shares tendered therewith and such
owner has not completed the box entitled "Special Payment Instructions" or the
box entitled "Special Delivery Instructions" on the Letter of Transmittal and
Consent, (b) such Shares are tendered for the account of an Eligible Institution
or (c) the Letter of Transmittal and Consent is being used solely for the
purpose of voting with respect to Shares which are not being tendered pursuant
to the Offer. See Instructions 1 and 5 of the Letter of Transmittal and Consent.
 
    GUARANTEED DELIVERY PROCEDURE.  If a Preferred Shareholder desires to tender
Shares pursuant to the Offer and such Preferred Shareholder's certificates are
not immediately available or the procedures for book-entry transfer cannot be
completed on a timely basis or time will not permit all required documents to
reach the Depositary prior to the Expiration Date, such Shares may nevertheless
be tendered if all of the following guaranteed delivery procedures are complied
with:
 
        (i) such tender is made by or through an Eligible Institution;
 
        (ii) a properly completed and duly executed Notice of Guaranteed
    Delivery and Consent, substantially in the form provided by the Company
    herewith, is received (with any required signatures or signature guarantees)
    by the Depositary on or prior to the Expiration Date; and
 
        (iii) the certificates for all tendered Shares in proper form for
    transfer or a book-entry confirmation with respect to all tendered Shares,
    together with a properly completed and duly executed Letter of Transmittal
    and Consent and any other documents required by the Letter of Transmittal
    and Consent, are received by the Depositary no later than 5:00 p.m., New
    York City time, within three business days after the date of delivery of
    such Notice of Guaranteed Delivery and Consent.
 
    THE NOTICE OF GUARANTEED DELIVERY AND CONSENT MAY BE DELIVERED BY HAND OR
MAILED TO THE DEPOSITARY AND MUST INCLUDE AN ENDORSEMENT BY AN ELIGIBLE
INSTITUTION IN THE FORM SET FORTH IN SUCH NOTICE OF GUARANTEED DELIVERY AND
CONSENT.
 
    In all cases, Shares shall not be deemed validly tendered unless a properly
completed and duly executed Letter of Transmittal and Consent is received by the
Depositary within the applicable time limits, and the consent of the record
holder to the Proposal has been granted with respect to such Shares.
 
    AVOIDING BACKUP WITHHOLDING TAX WHEN TENDERING.  To avoid federal income tax
backup withholding equal to 31% of the gross payment made pursuant to the Offer
or, alternatively, the Special Cash Payment, each tendering Preferred
Shareholder and each non-tendering Preferred Shareholder who grants his or her
consent to the Proposal must notify the Depositary of such Preferred
Shareholder's correct taxpayer identification number and provide certain other
information by properly completing and executing the Substitute Form W-9
included in the Letter of Transmittal and Consent (or, in the case of a foreign
preferred shareholder, must complete and execute Form W-8 obtainable from the
Depositary). See "Certain Federal Income Tax Considerations--Backup
Withholding."
 
    EACH PREFERRED SHAREHOLDER IS URGED TO CONSULT WITH HIS OR HER OWN TAX
ADVISOR REGARDING THE TAX CONSEQUENCES OF THE OFFER.
 
WITHDRAWAL RIGHTS
 
    Tenders of Shares made pursuant to the Offer may be withdrawn at any time
prior to the Expiration Date. Thereafter, such tenders are irrevocable, except
that they may be withdrawn after                   , 1999, unless previously
accepted for payment as provided herein.
 
    The consent accompanying any tendered Shares that are withdrawn will not be
considered revoked unless the Preferred Shareholder specifically revokes such
consent as described below under "Proposal and Consent Solicitation--Revocation
of Consents."
 
                                       9
<PAGE>
    To be effective, a written notice of withdrawal must be timely received by
the Depositary (at one of its
addresses set forth on the back cover hereof) and must specify the name of the
person who tendered the Shares to be withdrawn and the number of Shares to be
withdrawn. If the Shares to be withdrawn have been delivered to the Depositary,
a signed notice of withdrawal with signatures guaranteed by an Eligible
Institution (except in the case of Shares tendered by an Eligible Institution)
must be submitted prior to the release of such Shares. In addition, such notice
must specify, in the case of Shares tendered by delivery of certificates, the
name of the registered owner (if different from that of the tendering Preferred
Shareholder) and the serial numbers shown on the particular certificates
evidencing the Shares to be withdrawn or, in the case of Shares tendered by
book-entry transfer, the name and number of the account at the Book-Entry
Transfer Facility to be credited with the withdrawn Shares and the name of the
registered holder (if different from the name of such account). Withdrawals may
not be rescinded, and Shares withdrawn will thereafter be deemed not validly
tendered for purposes of the Offer. However, withdrawn Shares may be re-tendered
by again following the procedures described in "Terms of the Offer--Procedure
for Tendering Shares" at any time prior to the Expiration Date.
 
    All questions as to the form and validity (including time of receipt) of any
notice of withdrawal will be determined by the Company, in its sole discretion,
and its determination will be final and binding. None of the Company, the Dealer
Manager, the Depositary, the Information Agent nor any other person will be
under any duty to give notification of any defect or irregularity in any notice
of withdrawal or will incur any liability for failure to give any such
notification.
 
ACCEPTANCE OF SHARES FOR PAYMENT AND PAYMENT OF PURCHASE PRICE
 
    Upon the terms and subject to the conditions of the Offer, and as promptly
as practicable after the Expiration Date, the Company will accept for payment
(and thereby purchase) and pay for Shares validly tendered and not withdrawn as
permitted in "Terms of the Offer--Withdrawal Rights." Thereafter, payment for
all Shares accepted pursuant to the Offer will be made by the Depositary by
check as promptly as practicable after the Expiration Date. Notwithstanding any
other provision hereof, in all cases, payment for Shares accepted for payment
pursuant to the Offer will be made promptly but only after timely receipt by the
Depositary of certificates for, or a confirmation of a book-entry transfer with
respect to, such Shares, a properly completed and duly executed Letter of
Transmittal and Consent with any required signature guarantees and any other
required documents. Accordingly, tendering Preferred Shareholders may be paid at
different times depending upon when certificates for Shares or confirmations of
book-entry transfers are actually received by the Depositary.
 
    The Company will be deemed to have accepted for payment (and thereby have
purchased) Shares that are validly tendered and not withdrawn as, if and when it
gives oral and written notice to the Depositary of its acceptance for payment of
such Shares. The Company will pay for Shares that it has purchased pursuant to
the Offer by depositing the purchase price therefor with the Depositary, which
will act as agent for tendering Preferred Shareholders for the purpose of
receiving payment from the Company and transmitting payment to such Preferred
Shareholders. UNDER NO CIRCUMSTANCES WILL INTEREST ACCRUE OR BE PAID ON AMOUNTS
TO BE PAID BY THE COMPANY TO TENDERING PREFERRED SHAREHOLDERS, REGARDLESS OF ANY
EXTENSION OF THE OFFER OR DELAY IN MAKING SUCH PAYMENT. Certificates for all
Shares not validly tendered or accepted for payment will be returned or, in the
case of Shares tendered by book-entry transfer, such Shares will be credited to
an account maintained with the Book-Entry Transfer Facility, as promptly as
practicable, without expense to the tendering Preferred Shareholder.
 
    If the conditions to the Offer are not satisfied (or waived by the Company),
the Company will not be obligated to purchase Shares pursuant to the Offer. See
"Terms of the Offer--Conditions of the Offer."
 
    The Company will pay or cause to be paid any stock transfer taxes with
respect to the sale and transfer of any Shares to it or its order pursuant to
the Offer. If, however, payment of the purchase price is to be
 
                                       10
<PAGE>
made to, or if not all Shares represented by a certificate are tendered in the
Offer and the unpurchased Shares are to be registered in the name of, any person
other than the registered owner of the Shares, or if tendered Shares are
registered in the name of any person other than the person signing the Letter of
Transmittal and Consent, the amount of any stock transfer taxes (whether imposed
on the registered owner, such other person or otherwise) payable on account of
the transfer to such person will be deducted from the purchase price unless
satisfactory evidence of the payment of such taxes, or exemption therefrom, is
submitted. Each Preferred Shareholder will be responsible for paying any income
or gross receipts taxes imposed by any jurisdiction by reason of the sale of the
Shares and/or the Special Cash Payment. See Instruction 6 to the Letter of
Transmittal and Consent; see also "Proposal and Consent Solicitation-- Special
Cash Payments" and "Certain Federal Income Tax Considerations."
 
CONDITIONS OF THE OFFER
 
    THE COMPANY WILL NOT BE REQUIRED TO ACCEPT FOR PAYMENT OR PAY FOR ANY SHARES
TENDERED IF THE PROPOSAL IS NOT APPROVED BY HOLDERS OF AT LEAST A MAJORITY OF
THE VOTES OF SHARES OF THE OUTSTANDING SERIAL PREFERRED STOCK ENTITLED TO BE
CAST, CONSIDERED TOGETHER AS ONE CLASS. SEE "PROPOSAL AND CONSENT
SOLICITATION--RECORD DATE; VOTING SECURITIES; REQUIRED VOTE."
 
    In addition, notwithstanding any other provision of the Offer, the Company
will not be required to accept for payment or pay for any tendered Shares of any
Series of Preferred, and may terminate or amend the Offer with respect to such
Series of Preferred (by oral or written notice to the Depositary and timely
public announcement) or may postpone (subject to the requirements of the
Securities Exchange Act of 1934, as amended (the "Exchange Act") for prompt
payment for or return of Shares) the acceptance for payment of, or payment for,
Shares of such Series of Preferred that are tendered, if at any time on or after
                  , 1999, and on or before the Expiration Date, any of the
following shall have occurred:
 
        (a) there shall have been threatened, instituted or pending any action
    or proceeding by any government or governmental, regulatory or
    administrative agency, authority or tribunal or any other person, domestic
    or foreign, or before any court, authority, agency or tribunal that (i)
    challenges the acquisition of Shares pursuant to the Offer or otherwise in
    any manner relates to or affects the Offer or (ii) in the reasonable
    judgment of the Company, would or might materially and adversely affect the
    business, condition (financial or otherwise), income, operations or
    prospects of the Company, or of EEC and its subsidiaries taken as a whole,
    or otherwise materially impair in any way the contemplated future conduct of
    the business of EEC or any of its subsidiaries or materially impair the
    Offer's contemplated benefits to the Company;
 
        (b) there shall have been any action threatened, pending or taken, or
    approval withheld, or any statute, rule, regulation, judgment, order or
    injunction threatened, proposed, sought, promulgated, enacted, entered,
    amended, enforced or deemed to be applicable to the Offer or EEC or any of
    its subsidiaries, by any legislative body, court, authority, agency or
    tribunal that, in the Company's reasonable judgment, would or might directly
    or indirectly (i) make the acceptance for payment of, or payment for, some
    or all of the Shares illegal or otherwise restrict or prohibit consummation
    of the Offer; (ii) delay or restrict the ability of the Company, or render
    the Company unable to accept for payment or pay for some or all of the
    Shares; (iii) materially impair the contemplated benefits of the Offer to
    the Company (including materially increasing the effective interest cost of
    certain types of unsecured debt); or (iv) materially affect the business,
    condition (financial or otherwise), income, operations or prospects of the
    Company, or of EEC and its subsidiaries taken as a whole, or otherwise
    materially impair in any way the contemplated future conduct of the business
    of EEC or any of its subsidiaries;
 
        (c) there shall have occurred (i) any significant decrease in the market
    price of the Shares of such Series of Preferred; (ii) any change in the
    general political, market, economic or financial conditions in the United
    States or abroad that, in the reasonable judgment of the Company, would or
    might have
 
                                       11
<PAGE>
    a material adverse effect on the Company's business, operations, prospects
    or ability to obtain financing generally or the trading in the Shares or
    other equity securities of the Company or EEC; (iii) the declaration of a
    banking moratorium or any suspension of payments in respect of banks in the
    United States or any limitation on, or any event that, in the Company's
    reasonable judgment, would or might affect the extension of credit by
    lending institutions in the United States; (iv) the commencement of war,
    armed hostilities or other international or national calamity directly or
    indirectly involving the United States; (v) any general suspension of
    trading in, or limitation on prices for securities on any national
    securities exchange or in the OTC; (vi) in the case of any of the foregoing
    existing at the time of the commencement of the Offer, in the Company's
    reasonable judgment, a material acceleration or worsening thereof; (vii) any
    decline in either the Dow Jones Industrial Average or the Standard & Poor's
    Composite 500 Stock Index by an amount in excess of 15% measured from the
    close of business on                   , 1999; or (viii) a decline in the
    ratings accorded any of the Company's securities by Standard & Poor's Rating
    Services ("S&P"), Moody's Investors Service, Inc. ("Moody's") or Duff &
    Phelps, Inc. ("D&P") during the period beginning on the close of business on
                      , 1999, or an announcement by S&P, Moody's or D&P that it
    has placed any such rating under surveillance or review with negative
    implications;
 
        (d) any tender or exchange offer with respect to some or all of the
    Outstanding Serial Preferred Stock of the Company (other than the Offer) or
    other equity securities of the Company or EEC, or a merger, acquisition or
    other business combination proposal for the Company or EEC, shall have been
    proposed, announced or made by any person or entity; or
 
        (e) there shall have occurred any event or events that have resulted, or
    in the Company's reasonable judgment may result, in an actual or threatened
    change in the business, condition (financial or otherwise), income,
    operations, stock ownership or prospects of the Company, or of EEC and its
    subsidiaries taken as a whole; and, in the sole judgment of the Company,
    such event or events make it undesirable or inadvisable to proceed with the
    Offer or with such acceptance for payment or payment.
 
    The foregoing conditions (including the condition that the Proposal be
approved) are for the sole benefit of the Company and may be asserted by the
Company regardless of the circumstances (including any action or inaction by the
Company) giving rise to the failure of any such condition to be satisfied, and
any such condition may be waived by the Company, in whole or in part, at any
time and from time to time in its sole discretion. A decision by the Company to
terminate or otherwise amend the Offer, following the occurrence of any of the
foregoing or the failure of any condition to be satisfied, with respect to one
Series of Preferred will not create an obligation on behalf of the Company to
terminate or otherwise amend in a similar manner the Offer with respect to any
other Series of Preferred. The failure by the Company at any time to exercise
any of the foregoing rights shall not be deemed a waiver of any such right and
each such right shall be deemed an ongoing right which may be asserted at any
time and from time to time. Any determination by the Company concerning the
events described above will be final and binding on all parties.
 
TERMINATION; AMENDMENTS
 
    The Company expressly reserves the right, in its sole discretion, to, among
other things, terminate the Offer and not accept for payment or pay for any
Shares tendered (subject to Rule 13e-4(f)(5) under the Exchange Act, which
requires the Company either to pay the consideration offered or to return the
Shares tendered promptly after the termination or withdrawal of the Offer), upon
the occurrence of any of the conditions specified in "Terms of the
Offer--Conditions of the Offer" (by giving oral or written notice of such
termination to the Depositary, and making a public announcement thereof).
 
    Subject to compliance with applicable law, the Company further reserves the
right, in its sole discretion, to amend the Offer in any respect. Amendments to
the Offer may be made at any time or from
 
                                       12
<PAGE>
time to time effected by public announcement thereof, such announcement, in the
case of an extension, to be issued no later than 9:00 a.m., New York City time,
on the next business day after the previously scheduled Expiration Date. Any
public announcement made pursuant to the Offer will be disseminated promptly to
Preferred Shareholders affected thereby in a manner reasonably calculated to
inform such Preferred Shareholders of such change. Without limiting the manner
in which the Company may choose to make a public announcement, except as
required by applicable law, the Company shall have no obligation to publish,
advertise or otherwise communicate any such public announcement other than by
making a release to the Dow Jones News Service.
 
    If the Company materially changes the terms of the Offer or the information
concerning the Offer, or if it waives a material condition of the Offer, the
Company will disclose promptly such change and extend the Offer to the extent
required by Rules 13e-4(d)(2) and 13e-4(e)(2) under the Exchange Act. Those
rules require that the minimum period during which the Offer must remain open
following material changes in the terms of the Offer or information concerning
the Offer (other than a change in price, a change in percentage of securities
sought or a change in the dealer's solicitation fee) will depend on the facts
and circumstances, including the relative materiality of such terms of
information. The Securities and Exchange Commission (the "Commission") has
stated that, in its view, an offer should remain open for a minimum of five
business days from the date that a notice of such a material change is first
published, sent or given. Pursuant to Rule 13e-4(f)(1), if the Offer is
scheduled to expire at any time earlier than the expiration of a period ending
on the tenth business day from, and including, the date that the Company
publishes, sends or gives to Preferred Shareholders a notice that it will (i)
increase or decrease the price it will pay for Shares, (ii) decrease the
percentage of Shares it seeks, or (iii) increase or decrease the soliciting
dealers' fees, the Offer will be extended until the expiration of such ten
business day period.
 
    THE OFFER FOR ANY ONE SERIES OF PREFERRED IS INDEPENDENT OF THE OFFER FOR
ANY OTHER SERIES OF PREFERRED. IF THE COMPANY EXTENDS OR AMENDS ANY OFFER WITH
RESPECT TO ANY ONE SERIES OF PREFERRED FOR ANY REASON, THE COMPANY WILL HAVE NO
OBLIGATION TO EXTEND OR AMEND THE OFFER FOR ANY OTHER SERIES OF PREFERRED.

                       PROPOSAL AND CONSENT SOLICITATION
 
INTRODUCTION
 
    In addition to the Offer, this document relates to the solicitation of
consents by the Board of Directors of the Company with respect to the Proposal.
A separate Consent Statement is being mailed to the holders of the Company's
6.30% Series, since the 6.30% Series is not included in the Offer.
 
    Under the Company's Charter, the Company cannot, without the consent,
granted in writing without a meeting, or by a vote at a meeting, of the holders
of at least a majority of the votes entitled to be cast by the holders of the
aggregate number of shares of the Outstanding Serial Preferred Stock, considered
together as one class, issue or assume any unsecured notes, debentures or other
securities representing unsecured indebtedness, other than for the refunding of
outstanding debt securities theretofore issued or assumed by the Company or for
the redemption or retirement of all the shares of the Outstanding Serial
Preferred Stock, if, immediately after such issue or assumption, the total
principal amount of all unsecured notes, debentures or other securities
representing unsecured indebtedness then outstanding would exceed: (a) 10% of
the sum of (i) the total principal amount of all bonds or other securities
representing secured indebtedness issued or assumed by the Company and then to
be outstanding and (ii) the capital and surplus of the Company as then stated on
its books; plus (b) $10,000,000 (which additional amount was approved by the
holders of the Company's serial preferred stock in 1957); in addition, unsecured
indebtedness that the Company issues in connection with financing pollution
control facilities is specifically excluded from the calculation of unsecured
indebtedness pursuant to the consent of the holders of the Company's serial
preferred stock given in 1975 (collectively the "Present Limitation"). At
present, this would entitle the Company to have outstanding approximately $200
million in unsecured indebtedness, of which approximately $  million is
presently outstanding, in addition to unsecured indebtedness issued or to be
issued in connection with financing pollution control facilities. The Company is
seeking the consent of the holders of the Outstanding Serial Preferred Stock to
the issuance by the Company of up to $  of unsecured indebtedness in excess of
the Present Limitation. The Company believes that the ability to issue
additional unsecured indebtedness will provide the Company the flexibility to
obtain financing on terms more advantageous to the Company than would otherwise
be the case.
 
    Preferred Shareholders who wish to tender their Shares pursuant to the Offer
must grant their consent to the Proposal. However, Preferred Shareholders need
not tender their Shares in order to consent to the Proposal. Only holders of
record of the Company's Outstanding Serial Preferred Stock as of the Record Date
or persons obtaining an irrevocable proxy from such holders will be entitled to
grant consents.
 
SPECIAL CASH PAYMENTS
 
    Subject to the terms and conditions set forth in this document, if, but only
if, a Preferred Shareholder consents to the Proposal with respect to Shares but
does not tender those Shares and the Proposal is approved, the Company will make
the Special Cash Payment to such Preferred Shareholder in an amount equal to
$      for each such Share.
 
    PREFERRED SHAREHOLDERS WHO TENDER THEIR SHARES WILL NOT BE ENTITLED TO THE
SPECIAL CASH PAYMENT. RATHER, SUCH PREFERRED SHAREHOLDERS WILL BE ENTITLED TO
ONLY THE PURCHASE PRICE PER SHARE LISTED ON THE FRONT COVER OF THIS DOCUMENT.
 
    IF A HOLDER OF THE COMPANY'S OUTSTANDING SERIAL PREFERRED STOCK DOES NOT
GRANT HIS OR HER CONSENT TO THE PROPOSAL OR ABSTAINS, SUCH HOLDER SHALL NOT BE
ENTITLED TO THE SPECIAL CASH PAYMENT (REGARDLESS OF WHETHER THE PROPOSAL IS
APPROVED).

RECORD DATE; VOTING SECURITIES; REQUIRED VOTE
 
    The Record Date for determining those holders of the Company's Outstanding
Serial Preferred Stock entitled to grant consents to the Proposal will be
            , 1999. The Company has six series of Outstanding Serial Preferred
Stock and the record holders of all shares of the Company's Outstanding Serial
Preferred Stock will be considered together as one class with respect to the
Proposal. Each share of Outstanding Serial Preferred Stock is entitled to one
vote per share with respect to the Proposal. The shares of Outstanding Serial
Preferred Stock on             , 1999, are as follows:

</TABLE>
 
    The consent of the holders of record as of the Record Date of at least a
majority of the votes of shares of the Outstanding Serial Preferred Stock
entitled to be cast, considered together as one class, is required to approve
the Proposal. Thus, in order for the Proposal to be approved, the Company must
receive the consents of the holders representing at least 272,201 votes of
shares of the Outstanding Series Preferred Stock.
 
    PLEASE NOTE THAT THE FOLLOWING ACTIONS WILL HAVE THE SAME EFFECT AS
WITHHOLDING CONSENT TO THE PROPOSAL: (A) FAILING TO PROPERLY EXECUTE, DATE AND
RETURN A LETTER OF TRANSMITTAL AND CONSENT OR (B) EXECUTING, DATING AND
RETURNING A CONSENT FORM MARKED "WITHHOLD CONSENT" OR "ABSTAIN" AS TO THE
PROPOSAL. IF RETURNED CONSENT FORMS ARE EXECUTED AND DATED BUT NOT MARKED WITH
RESPECT TO THE PROPOSAL, THE SHAREHOLDER WILL BE DEEMED TO HAVE CONSENTED TO THE
PROPOSAL.
 
    The approval of the holders of the Company's common stock is not required
for the Proposal to be approved, and no consent is being solicited from such
holders.
 
CONSENTS
 
    The Company is a New York corporation and is, therefore, subject to the New
York Business Corporation Law (the "BCL"). The BCL permits action without a
meeting by less than unanimous written consent of shareholders where any
provision in a certificate of incorporation so provides. The Company's Charter
provides that so long as any shares of the Company's serial preferred stock are
outstanding, a majority of the votes entitled to be cast by the holders of the
aggregate number of shares of serial preferred stock then outstanding may
consent in writing without a meeting to the Company's issuance of unsecured
indebtedness in excess of the Present Limitation.
 
    The Proposal will become effective when duly completed, valid and unrevoked
consents to the Proposal, signed by the holders of record as of the Record Date
of at least a majority of the votes of shares of the Company's Outstanding
Serial Preferred Stock entitled to be cast, are delivered to the Company.
Consents accompanying tendered Shares will not be deemed delivered to the
Company unless and until the tendered Shares are accepted for payment. Preferred
Shareholders are requested to return their consents by the return date of
            , 1999.
 
                                       15
<PAGE>
    THE ENCLOSED CONSENT FORM, WHICH IS CONTAINED WITHIN THE APPLICABLE LETTER
OF TRANSMITTAL AND CONSENT (AND THE NOTICE OF GUARANTEED DELIVERY AND CONSENT),
IS BEING SOLICITED BY THE COMPANY'S BOARD, WHICH RECOMMENDS THAT YOU GRANT YOUR
CONSENT TO THE PROPOSAL.
 
PROCEDURAL INSTRUCTIONS
 
    Only holders of record of the Company's Outstanding Serial Preferred Stock
as of the Record Date or persons obtaining an irrevocable proxy from such
holders will be entitled to grant their consents.
 
    If a Preferred Shareholder is a record holder of shares of Outstanding
Serial Preferred Stock as of the close of business on the Record Date, such
Preferred Shareholder may consent to, withhold consent to or abstain with
respect to the Proposal by marking the "CONSENT," "WITHHOLD CONSENT" or
"ABSTAIN" box, as applicable, within the applicable Letter of Transmittal and
Consent (and the Notice of Guaranteed Delivery and Consent) and signing, dating
and returning it promptly in the enclosed postage-paid envelope. PREFERRED
SHAREHOLDERS GRANTING THEIR CONSENT TO THE PROPOSAL MUST USE THE CONSENT FORM
THAT IS A PART OF THE APPLICABLE LETTER OF TRANSMITTAL AND CONSENT WHETHER OR
NOT SHARES ARE BEING TENDERED PURSUANT TO THE OFFER.
 
    A Preferred Shareholder may grant a consent to the Proposal but not tender
Shares pursuant to the Offer. In such case, the Preferred Shareholder should
complete the consent form in the applicable Letter of Transmittal and Consent
but should not send certificates or effect a book-entry transfer of his or her
Shares. The same Letter of Transmittal and Consent may not be used to tender
Shares and to grant consent with respect to Shares which are not being tendered.
A Preferred Shareholder tendering a portion of his or her Shares and granting a
consent with respect to other Shares without tendering such Shares must submit
two separate Letters of Transmittal and Consent, one with respect to the
tendered Shares and one with respect to the Shares for which a consent is
granted but which are not tendered.
 
    If a Preferred Shareholder withholds consent or abstains, any purported
tender by such Preferred Shareholder will not be valid, and such Preferred
Shareholder will not be entitled to receive either the purchase price per Share
listed on the front cover of this document or the Special Cash Payment in
respect of his or her Shares. Any beneficial owner of Shares who is not the
registered holder of such Shares as of the Record Date (as would be the case for
any beneficial owner whose Shares are registered in the name of such owner's
broker, dealer, commercial bank, trust company or other nominees) must arrange
with the record holder to execute and deliver a consent form on such beneficial
owner's behalf.
 
    SINCE A CONSENT IS NECESSARY IN ORDER TO VALIDLY TENDER SHARES PURSUANT TO
THE OFFER AND ONLY PREFERRED SHAREHOLDERS OF RECORD AS OF THE RECORD DATE ARE
ENTITLED TO GRANT CONSENTS, PREFERRED SHAREHOLDERS WHO BECOME HOLDERS OF RECORD
OF SHARES AFTER THE RECORD DATE AND WHO WISH TO TENDER SUCH SHARES MUST OBTAIN
AND SUBMIT WITH THEIR TENDER AN IRREVOCABLE PROXY FROM THE HOLDER OF RECORD OF
SUCH SHARES AS OF THE RECORD DATE IN ORDER TO GRANT THEIR CONSENT TO THE
PROPOSAL. AFTER THE RECORD DATE, THE SHARES OF EACH SERIES OF PREFERRED WILL
TRADE "WITH PROXY." SETTLEMENT OF ALL TRADES AFTER THE RECORD DATE SHOULD
INCLUDE AN IRREVOCABLE PROXY FROM THE HOLDER OF RECORD OF SUCH SHARES AS OF THE
RECORD DATE.
 
    All questions as to the form and the validity (including the time of
receipt) of consents and the eligibility for the Special Cash Payment will be
determined by the Company in its sole discretion, and its determination will be
final and binding. The Company reserves the absolute right to reject any and all
consents that (i) it determines are not in proper form or (ii) the acceptance of
or the payment of the Special Cash Payment with respect to which may, in the
opinion of the Company's counsel, be unlawful. The Company also reserves the
absolute right to waive any defect or irregularity in any consent. None of
 
                                       16
<PAGE>
the Company, the Dealer Manager, the Depositary, the Information Agent nor any
other person will be under any duty to give notice of any defect or irregularity
in a consent, nor shall any of them incur any liability for failure to give any
such notice.
 
REVOCATION OF CONSENTS
 
    Executed consents may be revoked at any time prior to the time that the
Proposal becomes effective, provided that a written, dated revocation which
clearly identifies the consent being revoked is executed and delivered to the
Depositary at the address set forth on the back cover of this document. A
revocation may be in any written form validly signed by the record holder as of
the Record Date as long as it clearly states that the consent previously given
is no longer effective.
 
    Withdrawal of Shares tendered pursuant to the Offer will not itself revoke a
properly executed consent. Preferred Shareholders who wish to tender Shares
pursuant to the Offer must grant their consent to the Proposal with respect to
all such Shares. If a consent is withdrawn, the related Shares will not be
deemed to have been validly tendered.
 
    All questions as to the form and validity (including time of receipt) of any
notice of revocation will be determined by the Company, in its sole discretion,
and its determination will be final and binding. None of the Company, the Dealer
Manager, the Depositary, the Information Agent nor any other person will be
under any duty to give notification of any defect or irregularity in any notice
of revocation or will incur any liability for failure to give any such
notification.
 
APPRAISAL RIGHTS
 
    No appraisal rights under the BCL are available in connection with the
Proposal.
 
COST OF SOLICITATION
 
    The Company will bear the cost of the solicitation of consents by the Board.
Consents will be solicited by mail or by telephone. In addition, officers and
employees of the Company and its affiliates may also solicit consents personally
or by telephone; such persons will receive no additional compensation for these
services. The Company has engaged Georgeson & Company, Inc. to act as
Information Agent in connection with the Offer and the solicitation of consents
for a fee of $15,000, and reasonable out-of-pocket expenses. The Information
Agent has not been retained to make, and will not make, solicitations or
recommendations, other than conveying information related to the recommendations
of the Board, in connection with the Proposal.
 
    In connection with Salomon Smith Barney's engagement as Dealer Manager in
connection with the Offer, employees of Salomon Smith Barney will communicate in
person, by telephone or otherwise with Preferred Shareholders for the purpose of
assisting in the solicitation of consents in connection with the Proposal. If
the Proposal is approved, Salomon Smith Barney will receive a fee of $.50 per
Share for Shares not tendered but in respect of which a valid consent is
received. In addition, in connection with the solicitation of consents with
respect to the 6.30% Series, if the Proposal is approved, Salomon Smith Barney
will receive a fee of $.50 per share of the 6.30% Series in respect of which a
valid consent is received. In connection with the Offer, Salomon Smith Barney
may receive certain additional fees as described below under "Fees and
Expenses."
 
    If the Proposal is approved, Soliciting Dealers who solicit consents will
receive certain fees as described below under "Fees and Expenses."
 
    The Company has requested that brokerage houses and other custodians,
nominees and fiduciaries forward solicitation materials to the beneficial owners
of shares of the Company's Outstanding Serial Preferred Stock held of record by
such persons, and the Company will reimburse such brokers and other fiduciaries
for their reasonable out-of-pocket expenses incurred in connection therewith.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT
 
    The Company's Outstanding Serial Preferred Stock are the only securities of
the Company whose consent is required with respect to the Proposal. There were
approximately             holders of record of shares of the Company's
Outstanding Serial Preferred Stock as of             , 1999.
 
    Generally, under Section 13(d) of the Exchange Act, a beneficial owner of a
security is any person who directly or indirectly has or shares voting or
investment power over such security. No person or group is known by management
of the Company to be the beneficial owner of more than 5% of the shares of the
Company's Outstanding Serial Preferred Stock as of             , 1999 and none
of the Company's directors or executive officers own any shares of the Company's
Outstanding Serial Preferred Stock.
 
REASONS FOR THE PROPOSAL; CERTAIN EFFECTS OF THE PROPOSAL
 
    The Company believes that the approval of the Proposal would provide the
Company with greater flexibility to obtain financing on terms more advantageous
to the Company than would otherwise be the case. It would enable the Company to
issue unsecured debt to meet future financing requirements and for other
corporate purposes. Given that the utility industry is extremely capital
intensive, controlling and minimizing financing costs are essential ingredients
to operating efficiently in the new competitive environment. As competition has
intensified in the utility industry, financial flexibility and financial cost
structure has become increasingly important for the success of the Company.
 
    The Company believes that approval of the Proposal will play an important
role in increasing the financial flexibility and improving the financial cost
structure of the Company. Historically, the Company's long-term debt financing
has been accomplished through the issuance of first mortgage bonds. The issuance
of first mortgage bonds is generally more costly to the Company than unsecured
indebtedness because of the added expense of the New York mortgage recording
tax, which is generally approximately 0.8% of the principal amount of bonds
being issued. The Company anticipates changing the mix of debt securities toward
more issuances on an unsecured basis.
 
    At present, the Company cannot have outstanding more than approximately $200
million of unsecured indebtedness (in addition to unsecured indebtedness issued
or to be issued to finance pollution control facilities) without the required
consent of the Company's Outstanding Serial Preferred Stock but can incur
secured indebtedness without such consent. Accordingly, to the extent the
Proposal allows the Company to incur a greater amount of total indebtedness, and
such indebtedness increases the credit risks of the Company, the market price
and credit rating of the Outstanding Serial Preferred Stock could decline.
 
                        PRICE RANGE OF SHARES; DIVIDENDS
 
    The 3.75% Series is traded on the NYSE, under the symbol "      ," while the
4 1/2% Series, 4.40% Series, 4.15% (1954) Series, and 4.15% Series are traded in
the OTC under the symbols "            ," "            ," "            ," and
"            ," respectively. On       , 1999 the last reported sale price on
the NYSE for the 3.75% Series was $            , and the last reported bid
quotation as reported by the National Quotation Bureau, LLC was $            for
the 4 1/2% Series, $      for the 4.40% Series, $            for the 4.15%
(1954) Series and $      for the 4.15% Series. However, Preferred Shareholders
should be aware that the Shares of each Series of Preferred trade only
sporadically and on a limited basis and, therefore, the last reported sales
price may not necessarily reflect the then-current market value of the Shares.
 
    PREFERRED SHAREHOLDERS ARE URGED TO OBTAIN CURRENT MARKET QUOTATIONS, IF
AVAILABLE, FOR THE SHARES.

    The holders of the Company's Outstanding Serial Preferred Stock are entitled
to receive, if, when and as declared by the Board, cash dividends at the annual
rate specified for such preferred stock, and no more, cumulative and payable
quarterly on each January 1, April 1, July 1 and October 1. To date, the Company
has timely made all quarterly dividend payments on the Company's Outstanding
Serial Preferred Stock.
 
    The April 1999 dividend has been declared on the Company's Outstanding
Serial Preferred Stock, payable on April 1, 1999 to holders of record on March
10, 1999. A tender and purchase of Shares pursuant to the Offer will not deprive
a Preferred Shareholder of his or her right to receive the April 1999 dividend
on Shares held of record on March 10, 1999, regardless of whether such
Shareholder tenders his or her Shares in the Offer prior to that date. Tendering
Preferred Shareholders will not be entitled to any dividends in respect of any
later dividend periods (or any portion thereof).

<PAGE>
               PURPOSE OF THE OFFER; CERTAIN EFFECTS OF THE OFFER
 
    The Company believes that the purchase of the Shares and approval of the
Proposal at this time will provide the Company the flexibility to obtain
financing on terms more advantageous to the Company than would otherwise be the
case. In addition, the Offer gives Preferred Shareholders the opportunity to
sell their Shares at a price which the Company believes to be a premium to
generally prevailing market prices
on the date of the announcement of the Offer without the usual transaction costs
associated with a market sale. The Company expects to cancel any Shares
purchased pursuant to the Offer and restore such Shares to the status of
authorized but unissued shares.
 
    TRADING AND LIQUIDITY.  Any purchase of Shares of any Series of Preferred by
the Company in the Offer will reduce the number of Shares of that Series of
Preferred that might otherwise trade publicly or become available for purchase
and/or sale and will likely reduce the number of owners of Shares of that Series
of Preferred, which could adversely affect the liquidity and market value and
increase the price volatility of the Shares of that Series of Preferred not
purchased in the Offer.
 
    Equity securities which are less liquid because of a smaller outstanding
market value available for trading (the "float") may command a lower price than
would comparable equity securities with a greater float. Therefore, the market
price for Shares of a Series of Preferred that are not tendered and purchased in
the Offer may be affected adversely to the extent that the amount of Shares of
that Series of Preferred purchased pursuant to the Offer reduces the float. The
reduced float of a Series of Preferred may also make the trading price of the
Shares of that Series of Preferred that are not tendered and accepted for
payment more volatile. If the Offer is completed with respect to any Series of
Preferred, there can be no assurance that any trading market will exist for such
Series of Preferred following consummation of the Offer. To the extent a market
continues to exist for the Shares following consummation of the Offer for a
Series of Preferred, Shares of that Series of Preferred may trade at a discount
compared to current trading, depending on the market for shares with similar
features, the performance of the Company and other factors. There is no
assurance that an active market in the Shares will exist and no assurance as to
the prices at which the Shares may trade following the Offer.
 
    The Shares are currently registered under Section 12(g) of the Exchange Act,
except the 3.75% Series, which is registered under Section 12(b) of the Exchange
Act. If the Shares currently registered under Section 12(g) of the Exchange Act
are no longer held by 300 or more owners of record, the Company may apply to the
Commission for termination of such registration. In addition, the Company may
apply to delist and deregister the 3.75% Series. Such actions may substantially
reduce the information required to be furnished by the Company to holders of the
Shares and could make certain provisions of the Exchange Act no longer
applicable to the Company.
 
    As of             , 1999, there were       registered holders of the 3.75%
Series,       registered holders of the 4 1/2% Series,       registered holders
of the 4.40% Series,   registered holders of the 4.15% (1954) Series, and
registered holders of the 4.15% Series.
 
    FUTURE PURCHASES.  After the consummation of the Offer, the Company may
purchase additional Shares on the open market, in privately negotiated
transactions, through one or more tender offers, or otherwise. However, there
can be no assurance the Company will effect any such purchase. Any such purchase
may be on the same terms as, or on terms which are more or less favorable to
holders of Shares than, the terms of the Offer. However, Rule 13e-4(f)(6) under
the Exchange Act prohibits the Company and its affiliates from purchasing any
Shares of a Series of Preferred, other than pursuant to the Offer, until at
least ten business days after the Expiration Date with respect to that Series of
Preferred. Any future purchases of Shares by the Company would depend on many
factors, including the market price of the Shares, the Company's business and
financial position, and legal restrictions on the Company's ability to purchase
Shares, as well as general economic and market conditions.
 
                                       20
<PAGE>
    REDEMPTION OF SHARES; TERMS OF PREFERRED.  Preferred Shareholders are not
under any obligation to tender Shares pursuant to the Offer. The Offer does not
constitute a notice of redemption of any Series of Preferred pursuant to the
Company's Charter, nor does the Company intend to effect any such redemption by
making the Offer. Further, the Offer does not constitute a waiver by the Company
of any option it has to redeem Shares.
 
    Shares which are not tendered will continue to be subject to their current
redemption and liquidation provisions. The Series of Preferred are redeemable at
the option of the Company in whole or in part upon not less than thirty days and
not more than ninety days notice at the applicable redemption prices plus
accrued and unpaid dividends up to the date fixed for redemption. The 3.75%
Series is redeemable at a price equal to $104.00 per share, the 4 1/2% Series is
redeemable at a price equal to $103.75 per share, the 4.40% Series is redeemable
at a price equal to $102.00 per share, the 4.15% (1954) Series is redeemable at
a price equal to $102.00 per share and the 4.15% Series is redeemable at a price
equal to $101.00 per share. The holders of the Series of Preferred have no
preemptive or conversion rights.
 
    The amount or amounts per share payable in cash to the holders of a Series
of Preferred on any voluntary or involuntary liquidation, dissolution or
winding-up of the Company will be the amount or amounts (not less than the par
value thereof plus all dividends accumulated and unpaid thereon) fixed for such
Series of Preferred, and no more, before any amount may be paid to, or assets
distributed among, holders of stock ranking junior to such Series of Preferred.
The amount per share payable on a Series of Preferred in the event of any
voluntary liquidation, dissolution or winding-up of the Company shall be the
amount per share at which such Shares could be redeemed (other than through a
sinking fund, if any) as set forth above, and the amount per share payable on
the Series of Preferred in the event of any involuntary liquidation, dissolution
or winding-up shall be the par value thereof, together in each case with an
amount equal to accrued unpaid dividends to the date of such liquidation,
dissolution or winding-up.
 
    FUTURE CORPORATE ACTION.  Following the consummation of the Offer, the
Company expects that the business and operations of the Company will be
continued substantially as they are currently being conducted. Except as
disclosed herein and in the documents incorporated by reference, the Company has
no plans or proposals that would relate to or result in (a) the acquisition by
any person or entity of additional securities of the Company or the disposition
of securities of the Company, other than in the ordinary course of business; (b)
an extraordinary corporate transaction, such as a merger, reorganization, or
liquidation, involving the Company; (c) a sale or transfer of a material amount
of assets of the Company; (d) any change in the present Board or management of
the Company; (e) any material change in the present dividend rate or policy, or
indebtedness or capitalization of the Company; (f) any other material change in
the Company's corporate structure or business; (g) any change in the Charter or
any actions that may impede the acquisition of control of the Company by any
person; (h) a class of equity securities of the Company being delisted from a
national securities exchange; (i) a class of equity securities of the Company
becoming eligible for termination of registration pursuant to Section 12(g)(4)
of the Exchange Act; or (j) the suspension of the Company's obligation to file
reports pursuant to Section 15(d) of the Exchange Act.
 
    However, in order to adapt to the increasingly competitive environment in
which EEC and the Company operate, they will evaluate and consider a wide array
of potential business strategies. These may include business combinations or
acquisitions involving other utility or non-utility businesses or properties,
and internal restructurings or reorganizations involving EEC and/or the Company.
Furthermore, the Company and its affiliates may engage in other new business
ventures. Pursuit of any of the above strategies, or any combination thereof,
may significantly affect the business operations and financial condition of the
Company and its affiliates.
 
    NONE OF THE COMPANY, THE BOARD, NOR ANY OF THE COMPANY'S OFFICERS MAKES ANY
RECOMMENDATION TO ANY PREFERRED SHAREHOLDER AS TO WHETHER TO TENDER SHARES IN
THE OFFER. EACH PREFERRED SHAREHOLDER MUST MAKE HIS OR HER OWN DECISION AS TO
WHETHER TO TENDER SHARES AND, IF SO, HOW MANY SHARES TO TENDER.

                                RATING AGENCIES
 
    Moody's and S&P (the "Rating Agencies") have been advised of the Proposal.
The Rating Agencies have advised the Company that the adoption of the Proposal,
in and of itself, will not result in a reduction of the Outstanding Serial
Preferred Stock's current ratings.
 
    Ratings are not recommendations to purchase, hold or sell shares of the
Outstanding Serial Preferred Stock inasmuch as the ratings do not comment as to
market price or suitability for a particular investor. The ratings are based on
current information furnished to the Rating Agencies by the Company and obtained
from other sources. The ratings may be changed, suspended or withdrawn as a
result of changes in, or the unavailability of, such information.
 
                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
    The following summary describes certain United States federal income tax
considerations with respect to the sale of Shares pursuant to the Offer and the
receipt of Special Cash Payments in connection with the approval of the
Proposal. This summary is based on the Internal Revenue Code of 1986, as amended
to the date hereof (the "Code"), administrative pronouncements, judicial
decisions and existing and proposed Treasury Regulations, changes to any of
which subsequent to the date of this document may adversely affect the tax
consequences described herein, possibly on a retroactive basis. This summary is
addressed to Preferred Shareholders who hold Shares as capital assets within the
meaning of Section 1221 of the Code. This summary does not discuss all of the
tax consequences that may be relevant to a Preferred Shareholder in light of
such Preferred Shareholder's particular circumstances or to Preferred
Shareholders subject to special rules (including certain financial institutions,
tax-exempt organizations, insurance companies, dealers in securities or
currencies, or Preferred Shareholders who acquired their Shares as part of a
hedge or hedging transaction or as a position in a straddle for tax purposes).
PREFERRED SHAREHOLDERS SHOULD CONSULT THEIR TAX ADVISORS WITH REGARD TO THE
APPLICATION OF THE UNITED STATES FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR
SITUATIONS AS WELL AS ANY TAX CONSEQUENCES ARISING UNDER THE LAWS OF ANY STATE,
LOCAL OR FOREIGN TAXING JURISDICTION.
 
    As used herein, the term "United States Preferred Shareholder" means (i) a
citizen or resident of the United States for United States federal income tax
purposes; (ii) a corporation or partnership created or organized in or under the
laws of the United States or of any political subdivision thereof; (iii) an
estate the income of which is subject to United States federal income taxation
regardless of its source; or (iv) a trust if a court within the United States is
able to exercise primary supervision over the administration of such trust and
one or more United States persons have the authority to control all substantial
decisions of such trust. A "Non-United States Preferred Shareholder" is a
Preferred Shareholder that is not a United States Preferred Shareholder.
 
TAX CONSIDERATIONS FOR TENDERING PREFERRED SHAREHOLDERS
 
    UNITED STATES PREFERRED SHAREHOLDERS.  A United States Preferred Shareholder
will recognize a gain or loss equal to the difference between the tax basis of
such Preferred Shareholder's Shares and the amount of cash received in exchange
therefor. A United States Preferred Shareholder's gain or loss will be a capital
gain or loss. Capital gains of individuals derived in respect to capital assets
held for more than one year are eligible for reduced rates of taxation. The
deductibility of capital losses is subject to limitations.
 
                                       22
<PAGE>
    NON-UNITED STATES PREFERRED SHAREHOLDERS.  Any capital gain realized upon
the sale of Shares by a Non-United States Preferred Shareholder pursuant to the
Offer generally will not be subject to United States federal income tax unless
(i) such gain is effectively connected with the conduct of a trade or business
in the United States of the Non-United States Preferred Shareholder, or (ii) in
the case of a Non-United States Preferred Shareholder who is an individual, such
individual is present in the United States for 183 days or more in the taxable
year of such sale or exchange and certain other conditions are met. A Non-United
States Preferred Shareholder described in clause (i) above will be taxed on the
net capital gain derived from the sale at applicable graduated individual or
corporate rates. Any such effectively connected income received by a foreign
corporation may be subject to an additional "branch profits tax" at a 30% rate
(or such lower rate as may be specified by an applicable income tax treaty).
Unless an applicable tax treaty provides otherwise, an individual Non-United
States Preferred Shareholder described in clause (ii) above will be subject to a
flat 30% tax on the gain derived from the sale, which may be offset by United
States losses (notwithstanding the fact that the individual is not considered a
resident of the United States).
 
TAX CONSIDERATIONS FOR NON-TENDERING PREFERRED SHAREHOLDERS
 
    UNITED STATES PREFERRED SHAREHOLDERS.  There is no direct authority
concerning the federal income tax consequences of the receipt of Special Cash
Payments. The Company will, for information reporting purposes, treat Special
Cash Payments as ordinary non-dividend income to recipient United States
Preferred Shareholders.
 
    NON-UNITED STATES PREFERRED SHAREHOLDERS.  The Company will treat Special
Cash Payments paid to a Non-United States Preferred Shareholder as subject to
withholding of United States federal income tax at a 30% rate. However, Special
Cash Payments that are effectively connected with the conduct of a trade or
business by the Non-United States Preferred Shareholder within the United States
are not subject to the withholding tax (provided such Non-United States
Preferred Shareholder provides two originals of IRS Form 4224 stating that such
Special Cash Payments are so effectively connected), but instead are subject to
United States federal income tax on a net income basis at applicable graduated
individual or corporate rates. Any such effectively connected Special Cash
Payments received by a foreign corporation may be subject to an additional
"branch profits tax" at a 30% rate (or such lower rates as may be specified by
an applicable income tax treaty).
 
    A Non-United States Preferred Shareholder eligible for a reduced rate of
United States withholding tax pursuant to an income tax treaty may obtain a
refund of any excess amounts withheld by filing an appropriate claim for refund
with the Internal Revenue Service.
 
BACKUP WITHHOLDING
 
    ANY UNITED STATES PREFERRED SHAREHOLDER WHO FAILS TO COMPLETE AND SIGN THE
SUBSTITUTE FORM W-9 THAT IS INCLUDED IN THE APPLICABLE LETTER OF TRANSMITTAL AND
CONSENT (OR, IN THE CASE OF A NON-UNITED STATES PREFERRED SHAREHOLDER, FORM W-8,
OBTAINABLE FROM THE DEPOSITARY) MAY BE SUBJECT TO REQUIRED FEDERAL INCOME TAX
BACKUP WITHHOLDING OF 31% OF THE GROSS PROCEEDS PAYABLE TO SUCH PREFERRED
SHAREHOLDER PURSUANT TO THE OFFER OR, ALTERNATIVELY, THE SPECIAL CASH PAYMENT.
To prevent backup withholding, a United States Preferred Shareholder must
provide the Depositary with the Preferred Shareholder's correct taxpayer
identification number and certify that the Preferred Shareholder is not subject
to backup withholding of federal income tax by completing the Substitute Form
W-9 included in the applicable Letter of Transmittal and Consent. Certain
Preferred Shareholders (including, among others, all corporations and certain
foreign shareholders) are exempt from backup withholding. For a corporate United
States Preferred Shareholder to qualify for such exemption, such Preferred
Shareholder must provide the Depositary with a properly completed and executed
Substitute Form W-9 attesting to its exempt status. In
 
                                       23
<PAGE>
order for a Non-United States Preferred Shareholder to qualify as an exempt
recipient, the Non-United States Preferred Shareholder must submit a Form W-8,
Certificate of Foreign Status, signed under penalties of perjury, attesting to
that Preferred Shareholder's exempt status. A copy of Form W-8 may be obtained
from the Depositary. Any amount paid to Non-United States Preferred Shareholders
that is subject to the 31% backup withholding will not be subject to the 30%
withholding tax discussed above under "Tax Considerations for Non-Tendering
Preferred Shareholders--Non-United States Preferred Shareholders."
 
    The amount of any backup withholding from a payment to a Preferred
Shareholder will be allowed as a credit against such Preferred Shareholder's
United States federal income tax liability and may entitle such Preferred
Shareholder to a refund, provided that the required information is furnished to
the Internal Revenue Service.
 
                           SOURCE AND AMOUNT OF FUNDS
 
    Assuming that the Company purchases all outstanding Shares pursuant to the
Offer, the total amount required by the Company to purchase such Shares will be
approximately $         million, including fees and other expenses. The Company
intends to fund the Offer through the issuance of commercial paper.
 
               TRANSACTIONS AND AGREEMENTS CONCERNING THE SHARES
 
    Based upon the Company's records and upon information provided to the
Company by its directors and executive officers, neither the Company nor any of
its affiliates, directors or executive officers, or associates of the foregoing,
has engaged in any transactions involving Shares during the 40 business days
preceding the date hereof. Neither the Company nor, to the knowledge of the

    DEALER MANAGER FEES.  Salomon Smith Barney Inc. will act as Dealer Manager
for the Company in connection with the Offer. The Company has agreed to pay the
Dealer Manager a fee of an amount equal to $.50 per Share for any Shares
tendered, accepted for payment and paid for pursuant to the Offer and $.50 per
Share for any Shares with respect to which a consent is granted but not tendered
pursuant to the Offer. The Dealer Manager will also be reimbursed by the Company
for its reasonable out-of-pocket expenses and will be indemnified against
certain liabilities, including certain liabilities under the federal securities
laws, in connection with the Offer and the Consent Solicitation. The Dealer
Manager has rendered, is currently rendering and is expected to continue to

has received, and will continue to receive, customary compensation from the
Company for such services.
 
    The Company has retained ChaseMellon Shareholder Services, L.L.C., as
Depositary, and Georgeson & Company, Inc., as Information Agent, in connection
with the Offer and the Consent Solicitation. The Depositary and Information
Agent will receive reasonable and customary compensation for their services and
will also be reimbursed for reasonable out-of-pocket expenses, including
attorney fees. Neither the Depositary nor the Information Agent has been
retained to make solicitations or recommendations in connection with the Offer
and the Consent Solicitation.
 
    SOLICITED TENDER FEES.  The Company will pay a solicitation fee to
Soliciting Dealers of an amount equal to $1.50 per Share for Shares that are
tendered, accepted for payment and paid for pursuant to the Offer (except that
for transactions for beneficial owners whose ownership equals or exceeds 2,500
Shares, the Company will pay a solicitation fee equal to $1.00 per Share). If
the Proposal is approved, the Company will pay a solicitation fee to Soliciting
Dealers of $.50 per Share for Shares that are not tendered pursuant to the Offer
but in respect of which a consent to the Proposal is granted. With respect to
fees
 
                                       24
<PAGE>
payable pursuant to this paragraph involving transactions for beneficial owners
whose ownership is less than 2,500 Shares, any fees payable hereunder shall be
paid in full to the Dealer Manager unless a Soliciting Dealer is designated (as
herein described), in which case such fee shall be payable in full to such
designated Soliciting Dealer (which designated Soliciting Dealer may be the
Dealer Manager). With respect to fees payable pursuant to this paragraph
involving transactions for beneficial owners whose ownership equals or exceeds
2,500 Shares, any fees payable hereunder shall be paid in full to the Dealer
Manager unless a Soliciting Dealer is designated, in which case 80% of such fee
shall be paid to the Dealer Manager and 20% of such fee shall be paid to the
designated Soliciting Dealer (which designated Soliciting Dealer may be the
Dealer Manager).
 
    A designated Soliciting Dealer is an entity obtaining the tender and/or
consent, if the applicable Letter of Transmittal and Consent shall include its
name under the heading "Solicited Tenders and/or Consents," and it is (a) any
broker or dealer in securities, including the Dealer Manager in its capacity as
a dealer or broker, which is a member of any national securities exchange or of
the NASD, (b) any foreign broker or dealer not eligible for membership in the
NASD which agrees to conform to the NASD's Rules of Fair Practice in soliciting
tenders outside the United States to the same extent as though it were an NASD
member, or (c) any bank or trust company.
 
    No such solicitation fee shall be payable to a Soliciting Dealer with
respect to the tender and/or consent of Shares by a holder unless the Letter of
Transmittal and Consent accompanying such tender and/ or consent designates such
Soliciting Dealer. No such fee shall be paid to a Soliciting Dealer with respect
to Shares tendered or for which a consent has been granted for such Soliciting
Dealer's own account. If tendered Shares or Shares for which a consent has been
granted are registered in the name of such Soliciting Dealer, no such fee shall
be payable unless such Shares are held by such Soliciting Dealer as nominee and
such Shares are being tendered, and/or a consent is being granted for the
benefit of one or more beneficial owners identified on the applicable Letter of
Transmittal and Consent and such beneficial owner has designated such Soliciting
Dealer. Beneficial owners should complete the "Solicited Tenders and/or
Consents" box in the accompanying Letter of Transmittal and Consent to designate
a Soliciting Dealer. No such fee shall be payable to a Soliciting Dealer if such
Soliciting Dealer is required for any reason to transfer the amount of such fee
to a depositing holder (other than itself). No broker, dealer, bank, trust
company or fiduciary shall be deemed to be the agent of the Company, the
Depositary, the Information Agent or the Dealer Manager for purposes of the
Offer and Consent Solicitation.
 
    Soliciting Dealers will include any of the organizations described in
clauses (a), (b) and (c) above even when the activities of such organizations in
connection with the Offer and Consent Solicitation consist solely of forwarding
to clients materials relating to the Offer and Consent Solicitation, including
the applicable Letter of Transmittal and Consent, and tendering Shares or
granting consents as directed by beneficial owners thereof. No Soliciting Dealer
is required to make any recommendation to holders of Shares as to whether to
tender or refrain from tendering in the Offer or whether to grant or refrain
from granting a consent. No assumption is made, in making payment to any
Soliciting Dealer, that its activities in connection with the Offer included any
activities other than those described above, and for all purposes noted in all
materials relating to the Offer, the term "solicit" shall be deemed to mean no
more than "processing shares tendered or consents" or "forwarding to customers
materials regarding the Offer and Consent Solicitation."
 
    By accepting any solicitation fee, a person shall be deemed to have
represented that: (i) it has complied with the applicable requirements of the
Securities Exchange Act of 1934, as amended, and the applicable rules and
regulations thereunder, in connection with such solicitation; (ii) it is
entitled to such compensation for such solicitation under the terms and
conditions of the Offer; (iii) in soliciting tenders of Shares, it has used no
soliciting materials other than those furnished by the Company; and (iv) if it
is a foreign broker or dealer not eligible for membership in the NASD, it has
agreed to conform to the NASD's Rules of Fair Practice in making solicitations.
 
    STOCK TRANSFER TAXES.  The Company will pay all stock transfer taxes, if
any, payable on account of the acquisition of Shares by the Company pursuant to
the Offer, except in certain circumstances where special payment or delivery
procedures are utilized pursuant to Instruction 6 of the accompanying Letter of
Transmittal and Consent.

Shares but who cannot deliver their Shares and all other required documents to
the Depositary on or prior to the Expiration Date must tender their Shares
pursuant to the guaranteed delivery procedure set forth under the heading "Terms
of the Offer--Procedure for Tendering Shares" in the Offer to Purchase and
Consent Statement. A separate Notice of Guaranteed Delivery and Consent form has
been provided in order to comply with the guaranteed delivery procedure.
 
    A Preferred Shareholder who is the beneficial owner of shares which are held
by a broker, dealer, commercial bank, trust company or nominee must contact such
broker, dealer, commercial bank, trust company or nominee to either (i) arrange
for the record transfer of Shares to such Preferred Shareholder prior to
tendering or (ii) direct such Shares be properly tendered (including granting a
consent in respect thereof) on behalf of such Preferred Shareholder.
 
    THE METHOD OF DELIVERY OF SHARES AND ALL OTHER REQUIRED DOCUMENTS IS AT THE
OPTION AND RISK OF THE PREFERRED SHAREHOLDER. IF DELIVERY IS BY MAIL, REGISTERED
MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS RECOMMENDED. BECAUSE IT
IS THE TIME OF RECEIPT, NOT THE TIME OF MAILING, WHICH DETERMINES WHETHER A
TENDER HAS BEEN MADE PRIOR TO THE EXPIRATION DATE, SUFFICIENT TIME SHOULD BE
ALLOWED TO ASSURE TIMELY DELIVERY.
 
    No alternative, conditional or contingent tenders will be accepted. See
"Terms of the Offer--Number of Shares; Purchase Prices" in the Offer to Purchase
and Consent Statement. By executing this Letter of Transmittal and Consent, the
tendering shareholder waives any right to receive any notice of the acceptance
for payment of the Shares.
 
    3.  VOTING.  PREFERRED SHAREHOLDERS WHO WISH TO TENDER THEIR SHARES PURSUANT
TO THE OFFER MUST SUBMIT A DULY COMPLETED, VALID AND UNREVOKED CONSENT TO THE
PROPOSAL. HOWEVER, IT IS NOT NECESSARY TO TENDER SHARES IN ORDER TO CONSENT TO
THE PROPOSAL. By executing a Notice of Guaranteed Delivery and
 
                                       10
<PAGE>
Consent, a Preferred Shareholder is deemed to have tendered the Shares described
in such Notice of Guaranteed Delivery and Consent and to have granted consent to
the Proposal in accordance with the consent contained therein. IF CONSENT FORMS
CONTAINED WITHIN THIS LETTER OF TRANSMITTAL AND CONSENT (OR WITHIN A NOTICE OF
GUARANTEED DELIVERY AND CONSENT) ARE EXECUTED AND DATED BUT NOT MARKED WITH
RESPECT TO THE PROPOSAL, THE SHAREHOLDER WILL BE DEEMED TO HAVE CONSENTED TO THE
PROPOSAL. The Offer is being sent to all persons in whose names Shares are
registered on the books of the Company as of the close of business on
            , 1999, as well as to all persons in whose name Shares are
registered on the books of the Company as of the Record Date. Preferred
Shareholders who become holders of record of Shares after the Record Date and
who wish to tender such Shares must obtain and submit with their tender an
irrevocable proxy from the holder of record as of the Record Date in order to
grant their consent to the Proposal. Any holder of Shares held of record as of
the Record Date in the name of another must establish to the satisfaction of the
Company his or her entitlement to exercise or transfer such consent. This will
ordinarily require an irrevocable proxy by such record holder to and from each
successive transferee, including the holder, with each signature guaranteed by
an Eligible Institution. See Instruction 5. A form that may be used to obtain
such irrevocable proxy is included in the materials you received.
 
    4.  PARTIAL TENDER (NOT APPLICABLE TO SHAREHOLDERS WHO TENDER BY BOOK-ENTRY
TRANSFER).  If fewer than all the Shares represented by any certificate
delivered to the Depositary are to be tendered, fill in the number of Shares
that are to be tendered in the box above under the heading "Description of
Shares Tendered." In such case, a new certificate for the remainder of the
Shares represented by the old certificate will be sent to the person(s) signing
this Letter of Transmittal and Consent, unless otherwise provided in the box
above under the heading "Special Payment Instructions" or "Special Delivery
Instructions," as promptly as practicable following the expiration or
termination of the Offer. All Shares represented by certificates delivered to
the Depositary will be deemed to have been tendered unless otherwise indicated.
 
    5.  SIGNATURES ON THIS LETTER OF TRANSMITTAL AND CONSENT AND/OR NOTICE OF
GUARANTEED DELIVERY AND CONSENT; STOCK POWERS AND ENDORSEMENTS.  If either this
Letter of Transmittal and Consent or the Notice of Guaranteed Delivery and
Consent (together, the "Tender and Consent Documents") is signed by the
registered holder(s) of the Shares tendered hereby, the signature(s) must
correspond with the name(s) as written on the face of the certificates without
alteration, enlargement or any change whatsoever.
 
    If any of the Shares tendered or voted under either Tender and Consent
Document are held of record by two or more persons, all such persons must sign
such Tender and Consent Document.
 
    If any of the Shares tendered or voted under either Tender and Consent
Document are registered in different names or different certificates, it will be
necessary to complete, sign and submit as many separate applicable Tender and
Consent Documents as there are different registrations or certificates.
 
    If either Tender and Consent Document is signed by the registered holder(s)
of the Shares tendered hereby, no endorsements of certificates or separate stock
powers are required unless payment of the purchase price is to be made to, or
Shares not tendered or not purchased are to be registered in the name of, any
person other than the registered holder(s). Signatures on any certificates or
stock powers must be guaranteed by an Eligible Institution. See Instruction 1.
 
    If this Letter of Transmittal and Consent is signed by a person other than
the registered holder(s) of the Shares tendered hereby, certificates must be
endorsed or accompanied by appropriate stock powers, in either case, signed
exactly as the name(s) of the registered holder(s) appear(s) on the certificates
for such Shares. Signature(s) on any such certificate or stock powers must be
guaranteed by an Eligible Institution. See Instruction 1.
 
    If either Tender and Consent Document or any certificate or stock power is
signed by a trustee, executor, administrator, guardian, attorney-in-fact,
officer of a corporation or other person acting in a
 
                                       11
<PAGE>
fiduciary or representative capacity, such person should so indicate when
signing, and proper evidence satisfactory to the Company of the authority of
such persons to act must be submitted.
 
    6.  STOCK TRANSFER TAXES.  Except as set forth in this Instruction 6, the
Company will pay all stock transfer taxes, if any, payable on account of the
acquisition of Shares by the Company pursuant to the Offer. If, however, payment
of the purchase price is to be made to, or Shares not tendered or not purchased
are to be registered in the name of, any person other than the registered owner,
or if tendered Shares are registered in the name of any person other than the
person signing this Letter of Transmittal and Consent, the amount of any stock
transfer taxes (whether imposed on the registered owner, such other person or
otherwise) payable on account of the transfer to such person will be deducted
from the purchase price unless satisfactory evidence of the payment of such
taxes, or exemption therefrom, is submitted. See "Terms of the Offer--Acceptance
of Shares for Payment and Payment of Purchase Price" in the Offer to Purchase
and Consent Statement. EXCEPT AS PROVIDED IN THIS INSTRUCTION 6, IT WILL NOT BE
NECESSARY TO AFFIX TRANSFER TAX STAMPS TO THE CERTIFICATES REPRESENTING SHARES
TENDERED HEREBY.
 
    7.  SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS.  If the check for the
purchase price of any Shares purchased is to be issued in the name of, any
Shares not tendered or not purchased are to be returned to or the check for the
Special Cash Payment is to be issued in the name of, a person other than the
person(s) signing this Letter of Transmittal and Consent or if the check and/or
any certificate for Shares not tendered or not purchased are to be mailed to
someone other than the person(s) signing this Letter of Transmittal and Consent
or to an address other than that shown in the box above under the heading
"Name(s) and Address(es) of Registered Holder(s)," then the "Special Payment
Instructions" and/or "Special Delivery Instructions" on this Letter of
Transmittal and Consent must be completed. Preferred Shareholders tendering
Shares by book-entry transfer will have any Shares not accepted for payment
returned by crediting the account maintained by such Preferred Shareholders at
the Book-Entry Transfer Facility.
 
    8.  SUBSTITUTE FORM W-9 AND FORM W-8.  A tendering Preferred Shareholder and
a Preferred Shareholder granting consent to the Proposal (but not tendering) are
required to provide the Depositary with (i) in the case of a United States
Preferred Shareholder, a correct Taxpayer Identification Number ("Taxpayer
Identification Number" or "TIN") and a certification that the Internal Revenue
Service has not notified such shareholder that he or she is subject to backup
withholding on the Substitute Form W-9 contained herein, or (ii) in the case of
a foreign Preferred Shareholder, a properly completed Form W-8, as hereinafter
discussed under "Important Tax Information." Failure to provide the information
on either Substitute Form W-9 or Form W-8 may subject the holder to a $50
penalty imposed by the Internal Revenue Service and to 31% federal income tax
backup withholding on the gross amount payable. The box in Part 2 of Substitute
Form W-9 may be checked if the holder has not been issued a TIN and has applied
for a number or intends to apply for a number in the near future. If the box in
Part 2 is checked and the Depositary is not provided with a TIN by the time of
payment, the Depositary will withhold 31% of the gross amount otherwise payable
thereafter until a TIN is provided to the Depositary.
 
    9.  REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.  Any questions or requests
for assistance or additional copies of the Offer and consent materials should be
directed to the Information Agent or the Dealer Manager at their respective
telephone numbers and addresses listed on the back cover of the Offer to
Purchase and Consent Statement. Preferred Shareholders may also contact their
local broker, dealer, commercial bank or trust company for assistance concerning
the Offer.
 
    10.  IRREGULARITIES.  All questions as to the form of documents and the
validity, eligibility (including the time of receipt) and acceptance for payment
of any tender of Shares and the form and validity (including time of receipt) of
consents and the eligibility for the Special Cash Payment will be determined by
the Company in its sole discretion, and its determination will be final and
binding. The Company reserves the absolute right to reject any and all tenders
and/or consents that it determines are
 
                                       12
<PAGE>
not in proper form or the acceptance of or payment for which may, in the opinion
of the Company, be unlawful. The Company also reserves the absolute right to
waive any defect or irregularity in any tender of Shares. None of the Company,
the Dealer Manager, the Depositary, the Information Agent nor any other person
will be under any duty to give notice of any defect or irregularity in tenders,
nor shall any of them incur any liability for failure to give any such notice.
 
    11.  LOST, DESTROYED OR STOLEN CERTIFICATES.  If any of your certificate(s)
for Shares have been lost, stolen or destroyed, please call the Depositary at
(800) 777-3674 (toll free). You may need to complete an Affidavit of Loss with
respect to the lost certificate(s) (which will be provided by the Depositary)
and payment of an indemnity bond premium fee may be required. The tender of
Shares pursuant to this Letter of Transmittal and Consent will not be valid
unless prior to the Expiration Date: (a) such procedures have been completed and
a replacement certificate for the Shares has been delivered to the Depositary or
(b) a Notice of Guaranteed Delivery and Consent has been delivered to the
Depositary. See Instruction 2.
 
                                       13
<PAGE>
                           IMPORTANT TAX INFORMATION
 
    Under federal income tax law, a Preferred Shareholder whose tendered Shares
are accepted for payment or who will receive a Special Cash Payment as a result
of granting consent to the Proposal is required to provide the Depositary (as
payer) with either such Preferred Shareholder's correct TIN on Substitute Form
W-9 below or a properly completed Internal Revenue Service Form W-8 (a "Form
W-8"). If such Preferred Shareholder is an individual, the TIN is his or her
social security number. For businesses and other entities, the number is the
federal employer identification number. If the Depositary is not provided with
the correct TIN or properly completed Form W-8, the Preferred Shareholder may be
subject to a $50 penalty imposed by the Internal Revenue Code. In addition,
payments that are made to such Preferred Shareholder with respect to Shares
purchased pursuant to the Offer may be subject to 31% backup withholding.
 
    Certain Preferred Shareholders (including, among others, all corporations
and certain foreign individuals) are exempt from backup withholding. For a
corporate United States Preferred Shareholder to qualify for such exemption,
such Preferred Shareholder must provide the Depositary with a properly completed
and executed Substitute Form W-9 attesting to its exempt status. In order for a
foreign Preferred Shareholder to qualify as an exempt recipient, such Preferred
Shareholder must submit to the Depositary a properly completed Form W-8, signed
under penalties of perjury, attesting to that Preferred Shareholder's exempt
status. A Form W-8 can be obtained from the Depositary. See the enclosed
Guidelines for Certification of Taxpayer Identification Number on Substitute
Form W-9 for additional instructions.
 
    If federal income tax backup withholding applies, the Depositary is required
to withhold 31% of any payments made to the Preferred Shareholder. Backup
withholding is not an additional tax. Rather, the federal income tax liability
of persons subject to backup withholding will be reduced by the amount of the
tax withheld. If withholding results in an overpayment of taxes, a refund may be
obtained from the Internal Revenue Service.
 
PURPOSE OF SUBSTITUTE FORM W-9 AND FORM W-8
 
    To avoid backup withholding on a Special Cash Payment(s) or payments made to
a Preferred Shareholder with respect to Shares purchased pursuant to the Offer,
the Preferred Shareholder is required to notify the Depositary of his or her
correct TIN by completing the Substitute Form W-9 attached hereto certifying
that the TIN provided on Substitute Form W-9 is correct and that (a) the
Preferred Shareholder has not been notified by the Internal Revenue Service that
he or she is subject to federal income tax backup withholding as a result of
failure to report all interest or dividends or (b) the Internal Revenue Service
has notified the Preferred Shareholder that he or she is no longer subject to
federal income tax backup withholding. Foreign Preferred Shareholders must
submit a properly completed form W-8 in order to avoid the applicable backup
withholding; provided, however, that backup withholding will not apply to
foreign Preferred Shareholders subject to withholding under other provisions of
the Code or the Special Cash Payment or on gross payments received pursuant to
the Offer. Foreign Preferred Shareholders that submit a properly completed Form
W-8 may nevertheless be subject to withholding under other provisions of the
Code on the payments received by them.

    The undersigned hereby tenders to the Company, upon the terms and subject to
the conditions set forth in the Offer to Purchase and Consent Statement, dated

acknowledged, the number of Shares listed below, pursuant to the guaranteed

Shares" in the Offer to Purchase and Consent Statement.
 
    Preferred Shareholders who wish to tender their Shares pursuant to the Offer
must submit a duly completed, valid and unrevoked consent to the Proposal.
However, it is not necessary to tender Shares in order to consent to the
Proposal. Included in this Notice of Guaranteed Delivery is a form for granting
such consent.
 
    In order to validly tender Shares pursuant to the Offer, Preferred
Shareholders who become holders of record of Shares after
                                , 1999 (the "Record Date") and who wish to
tender such Shares must obtain and submit with their tender an irrevocable proxy
from the holder of record of such Shares as of the Record Date in order to grant
their consent to the Proposal. Included in the materials you received is a form
that may be used to obtain such irrevocable proxy.
 
    If, but only if, a Preferred Shareholder consents to the Proposal with
respect to Shares but does not tender those Shares and the Proposal is approved,
the Company will make a special cash payment to such Preferred Shareholder in an
amount equal to $         for each such Share (the "Special Cash Payment").
Those Preferred Shareholders who validly tender their Shares will be entitled
only to the purchase price per Share listed above and will not be entitled to
the Special Cash Payment.
 
    NOTE: THE FOLLOWING ACTIONS WILL HAVE THE SAME EFFECT AS WITHHOLDING CONSENT
TO THE PROPOSAL: (A) FAILING TO EXECUTE, DATE AND RETURN A CONSENT FORM OR (B)
EXECUTING, DATING AND RETURNING A CONSENT MARKED "WITHHOLD CONSENT" OR "ABSTAIN"
AS TO THE PROPOSAL. IF RETURNED CONSENT FORMS ARE EXECUTED AND DATED BUT NOT
MARKED WITH RESPECT TO THE PROPOSAL, THE SHAREHOLDER WILL BE DEEMED TO HAVE
CONSENTED TO THE PROPOSAL.

To Brokers, Dealers, Commercial Banks,
  Trust Companies and Other Nominees:
 
    In our capacity as Dealer Manager, we are enclosing the materials listed
below relating to the invitation of New York State Electric & Gas Corporation
(the "Company"), a New York corporation, to the holders of each series of serial
preferred stock of the Company listed above (each a "Series of Preferred," and
the holder thereof, a "Preferred Shareholder") to tender any and all of their
shares (the "Shares") for purchase at the purchase price per Share listed above,
net to the seller in cash, upon the terms and subject to the conditions set
forth in the Offer to Purchase and Consent Statement, dated            , 1999
and in the applicable Letter of Transmittal and Consent (which together
constitute the "Offer"). The Company will purchase any and all Shares validly
tendered and not withdrawn, upon the terms and subject to the conditions set
forth in the Offer. In conjunction with the Offer, the Company is soliciting
consents from holders of each Series of Preferred with respect to a proposal to
permit the issuance by the Company of additional unsecured indebtedness in
excess of all other unsecured indebtedness presently authorized, permitted or
previously consented to, as described in the Offer (the "Proposal").
 
    If, but only if, a Preferred Shareholder consents to the Proposal with
respect to Shares but does not tender those Shares and the Proposal is approved,
the Company will make a special cash payment to such Preferred Shareholder in an
amount equal to $    for each such Share (the "Special Cash Payment"). Those
Preferred Shareholders who validly tender their Shares will be entitled only to
the purchase price per Share listed above and will not be entitled to the
Special Cash Payment.
 
    The Offer is conditioned upon, among other things, the approval of the
Proposal by holders of at least a majority of the votes of shares of the
Company's outstanding serial preferred stock entitled to be cast (which includes
each Series of Preferred and the Company's 6.30% Serial Preferred Stock
(Cumulative, $100 Par Value) which is not subject to the Offer), considered
together as one class. The Offer for any one Series of Preferred is not
conditioned upon any minimum number of Shares of such Series of Preferred being
tendered and is independent of the Offer for any other Series of Preferred.
 
    PREFERRED SHAREHOLDERS WHO WISH TO TENDER THEIR SHARES PURSUANT TO THE OFFER
MUST SUBMIT A DULY COMPLETED, VALID AND UNREVOKED CONSENT TO THE PROPOSAL, WHICH
IS CONTAINED IN THE APPLICABLE LETTER OF TRANSMITTAL AND CONSENT. HOWEVER, IT IS
NOT NECESSARY TO TENDER SHARES IN ORDER TO CONSENT TO THE PROPOSAL.
<PAGE>
    In order to validly tender Shares pursuant to the Offer, Preferred
Shareholders who become holders of record of Shares after               , 1999
(the "Record Date") and who wish to tender such Shares must obtain and submit
with their tender an irrevocable proxy from the holder of record of such Shares
as of the Record Date in order to grant their consent to the Proposal. In order
to facilitate receipt of consents, the Shares of each Series of Preferred will
trade "with proxy" in the over-the-counter market and on the New York Stock
Exchange, as applicable.
 
    The New York Stock Exchange (the "NYSE"), the National Association of
Securities Dealers, Inc. (the "NASD") and The Depository Trust Company (the
"DTC") have issued notices informing their members and participants that the
Shares will trade "with proxy" and that settlement of all trades after the
Record Date should include an irrevocable proxy from the holder of record of
such Shares as of the Record Date.
 
    We are asking you to contact your clients for whom you hold Shares
registered in your name (or in the name of your nominee) or for whom you hold
Shares registered in their own names. Please bring the Offer to their attention
as promptly as possible.
 
    For your information and for forwarding to your clients, we are enclosing
the following documents:
 
        1. The Offer to Purchase and Consent Statement, dated             ,
    1999.
 
        2. A separate Letter of Transmittal and Consent for each Series of
    Preferred.
 
        3. A letter to Preferred Shareholders from the Company.
 
        4. A Notice of Guaranteed Delivery and Consent.
 
        5. A form of letter which may be sent to your clients for obtaining such
    clients' instructions with regard to the Offer and the consent solicitation.
 
        6. A form of irrevocable proxy that may be used to obtain the proxy of
    holders of record of Shares as of the Record Date.
 
        7. Guidelines for Certification of Taxpayer Identification Number on
    Substitute Form W-9, providing information relating to backup federal income
    tax withholding.
 
        8. A return envelope addressed to ChaseMellon Shareholder Services,
    L.L.C., the Depositary.
 
    EACH SERIES OF PREFERRED HAS ITS OWN LETTER OF TRANSMITTAL AND CONSENT, AND
ONLY THE APPLICABLE LETTER OF TRANSMITTAL AND CONSENT FOR A PARTICULAR SERIES
MAY BE USED FOR SUCH SERIES OF PREFERRED.
 
SOLICITATION FEES AND EXPENSES
 
    The Company will pay a solicitation fee of an amount equal to $1.50 per
Share for Shares that are tendered, accepted for payment and paid for pursuant
to the Offer (except that for transactions for beneficial owners whose ownership
equals or exceeds 2,500 Shares, the Company will pay a solicitation fee equal to
$1.00 per Share). If the Proposal is approved, the Company will pay a
solicitation fee to Soliciting Dealers of $.50 per Share for Shares that are not
tendered pursuant to the Offer but in respect of which a consent to the Proposal
is granted. With respect to fees payable pursuant to this paragraph involving
transactions for beneficial owners whose ownership is less than 2,500 Shares,
any fees payable hereunder shall be paid in full to the Dealer Manager unless a
Soliciting Dealer is designated (as herein described), in which case such fee
shall be payable in full to such designated Soliciting Dealer (which designated
Soliciting Dealer may be the Dealer Manager). With respect to fees payable
pursuant to this paragraph involving transactions for beneficial owners whose
ownership equals or exceeds 2,500 Shares, any fees payable hereunder shall be
paid in full to the Dealer Manager unless a Soliciting Dealer is designated, in
 
                                       2
<PAGE>
which case 80% of such fee shall be paid to the Dealer Manager and 20% of such
fee shall be paid to the designated Soliciting Dealer (which designated
Soliciting Dealer may be the Dealer Manager).
 
    A designated Soliciting Dealer shall be named under the heading "Solicited
Tenders and/or Consents" in the applicable Letter of Transmittal and Consent and
shall have solicited and obtained the tender and/or consent, and shall also be
(a) any broker or dealer in securities, including the Dealer Manager in its
capacity as a dealer or broker, which is a member of any national securities
exchange or of the NASD, (b) any foreign broker or dealer not eligible for
membership in the NASD which agrees to conform to the NASD's Rules of Fair
Practice in soliciting tenders outside the United States to the same extent as
though it were an NASD member, or (c) any bank or trust company (each of which
is referred to herein as a "Soliciting Dealer").
 
    No such solicitation fee shall be payable to a Soliciting Dealer with
respect to the tender and/or consent of Shares by a holder unless the applicable
Letter of Transmittal and Consent accompanying such tender and/or consent
designates such Soliciting Dealer. No such fee shall be paid to a Soliciting
Dealer with respect to Shares tendered or Shares for which a consent has been
granted for such Soliciting Dealer's own account. If tendered Shares or Shares
for which a consent has been granted are registered in the name of such
Soliciting Dealer, no such fee shall be payable unless such Shares are held by
such Soliciting Dealer as nominee and such Shares are being tendered and/or a
consent is being granted for the benefit of one or more beneficial owners
identified on the applicable Letter of Transmittal and Consent and such
beneficial owner has designated such Soliciting Dealer. Beneficial owners should
complete the "Solicited Tenders and/or Consents" box in the accompanying Letter
of Transmittal and Consent to designate a Soliciting Dealer. No such fee shall
be payable to a Soliciting Dealer if such Soliciting Dealer is required for any
reason to transfer the amount of such fee to a beneficial owner. No broker,
dealer, bank, trust company or fiduciary shall be deemed to be the agent of the
Company, the Depositary, the Information Agent or the Dealer Manager for
purposes of the Offer and Consent Solicitation.
 
    Soliciting Dealers will include any of the organizations described in
clauses (a), (b) and (c) above even when the activities of such organizations in
connection with the Offer and Consent Solicitation consist solely of forwarding
to clients materials relating to the Offer and Consent Solicitation, including
the applicable Letter of Transmittal and Consent, and tendering Shares or
granting consents as directed by beneficial owners thereof. No Soliciting Dealer
is required to make any recommendation to holders of Shares as to whether to
tender or refrain from tendering in the Offer or whether to grant or refrain
from granting a consent. No assumption is made, in making payment to any
Soliciting Dealer, that its activities in connection with the Offer included any
activities other than those described above, and for all purposes noted in all
materials relating to the Offer, the term "solicit" shall be deemed to mean no
more than "processing shares tendered or consents" or "forwarding to customers
materials regarding the Offer and Consent Solicitation."
 
    By accepting any solicitation fee, a person shall be deemed to have
represented that: (i) it has complied with the applicable requirements of the
Securities Exchange Act of 1934, as amended, and the applicable rules and
regulations thereunder, in connection with such solicitation; (ii) it is
entitled to such compensation for such solicitation under the terms and
conditions of the Offer; (iii) in soliciting tenders and/or consent, it has used
no soliciting materials other than those furnished by the Company; and (iv) if
it is a foreign broker or dealer not eligible for membership in the NASD, it has
agreed to conform to the NASD's Rules of Fair Practice in making solicitations.
 
    The Company will, upon request, reimburse you for reasonable and customary
handling and mailing expenses incurred by them in forwarding materials relating
to the Offer to their customers. The Company will pay all stock transfer taxes

    IN ORDER FOR A SOLICITING DEALER TO RECEIVE A SOLICITATION FEE, SUCH
SOLICITING DEALER MUST BE DESIGNATED AS SUCH ON THE APPLICABLE LETTER OF
TRANSMITTAL AND CONSENT.
 
    All questions as to the validity, form and eligibility (including time of
receipt) of any designation of a Soliciting Dealer will be determined by the
Company, in its sole discretion, which determination will be final and binding.
Neither the Company nor any other person will be under any duty to give
notification of any defects or irregularities in any designation of a Soliciting
Dealer or incur any liability for failure to give such notification.
 
    THE SAME LETTER OF TRANSMITTAL AND CONSENT MAY NOT BE USED TO TENDER SHARES
AND TO GRANT CONSENT WITH RESPECT TO SHARES WHICH ARE NOT BEING TENDERED. A
PREFERRED SHAREHOLDER TENDERING A PORTION OF HIS OR HER SHARES AND GRANTING A
CONSENT WITH RESPECT TO OTHER SHARES WITHOUT TENDERING SUCH SHARES MUST SUBMIT
TWO SEPARATE LETTERS OF TRANSMITTAL AND CONSENT, ONE WITH RESPECT TO THE
TENDERED SHARES AND ONE WITH RESPECT TO THE SHARES FOR WHICH A CONSENT IS
GRANTED BUT WHICH ARE NOT TENDERED.

USED FOR EACH DELIVERY BY BOOK ENTRY TRANSFER.

                                                                          , 1999
 
    To Our Clients:
 
    Enclosed for your consideration are the Offer to Purchase and Consent
Statement, dated            , 1999, and a separate Letter of Transmittal and
Consent for each series of serial preferred stock listed above (each a "Series
of Preferred," and the holder thereof, a "Preferred Shareholder") of New York
State Electric & Gas Corporation (the "Company"), a New York corporation, of
which you own shares. The Company invites the holders of shares (the "Shares")
of the Series of Preferred listed above to tender any and all of their Shares
for purchase at the purchase price per Share listed above, net to the seller in
cash, upon the terms and subject to the conditions set forth in the Offer to
Purchase and Consent Statement and in the applicable Letter of Transmittal and
Consent (which together constitute the "Offer"). The Company will purchase any
and all Shares validly tendered and not withdrawn, upon the terms and subject to
the conditions set forth in the Offer. In conjunction with the Offer, the
Company is soliciting consents from holders of each Series of Preferred with
respect to a proposal to permit the issuance by the Company of additional
unsecured indebtedness in excess of all other unsecured indebtedness presently
authorized, permitted or previously consented to, as described in the Offer (the
"Proposal").
 
    If, but only if, a Preferred Shareholder consents to the Proposal with
respect to Shares but does not tender those Shares and the Proposal is approved,
the Company will make a special cash payment to such Preferred Shareholder in an
amount equal to $      for each such Share (the "Special Cash Payment"). Those
Preferred Shareholders who validly tender their Shares will be entitled only to
the purchase price per Share listed above and will not be entitled to the
Special Cash Payment.
 
    The Offer is conditioned upon, among other things, the approval of the
Proposal by holders of at least a majority of the votes of shares of the
Company's outstanding serial preferred stock entitled to be cast (which includes
each Series of Preferred and the Company's 6.30% Serial Preferred Stock
(Cumulative, $100 Par Value) which is not subject to the Offer), considered
together as one class. The Offer for any one Series of Preferred is not
conditioned upon any minimum number of Shares of such Series of Preferred being
tendered and is independent of the Offer for any other Series of Preferred.
 
    PREFERRED SHAREHOLDERS WHO WISH TO TENDER THEIR SHARES PURSUANT TO THE OFFER
MUST SUBMIT A DULY COMPLETED, VALID AND UNREVOKED CONSENT TO THE PROPOSAL, WHICH
IS CONTAINED IN THE APPLICABLE LETTER OF TRANSMITTAL AND CONSENT. HOWEVER, IT IS
NOT NECESSARY TO TENDER SHARES IN ORDER TO CONSENT TO THE PROPOSAL.
 
    In order to validly tender Shares pursuant to the Offer, Preferred
Shareholders who become holders of record of Shares after            , 1999 (the
"Record Date") and who wish to tender such Shares
<PAGE>
must obtain and submit with their tender an irrevocable proxy from the holder of
record of such Shares as of the Record Date in order to grant their consent to
the Proposal. In order to facilitate receipt of consents, the Shares of each
Series of Preferred will trade "with proxy" in the over-the-counter market and
on the New York Stock Exchange, as applicable.
 
    The New York Stock Exchange (the "NYSE"), the National Association of
Securities Dealers, Inc. (the "NASD") and The Depository Trust Company (the
"DTC") have issued notices informing their members and participants that the
Shares will trade "with proxy" and that settlement of all trades after the
Record Date should include an irrevocable proxy from the holder of record of
such Shares as of the Record Date.
 
    WE ARE THE HOLDER OF RECORD OF SHARES HELD FOR YOUR ACCOUNT BUT NOT
REGISTERED IN YOUR NAME. A TENDER OF SUCH SHARES OR CONSENT WITH RESPECT TO SUCH
SHARES TO THE PROPOSAL CAN BE MADE ONLY BY US AS THE HOLDER OF RECORD AND
PURSUANT TO YOUR INSTRUCTIONS. ANY LETTER OF TRANSMITTAL AND CONSENT FURNISHED
TO YOU IS SOLELY FOR YOUR INFORMATION AND CANNOT BE USED BY YOU TO TENDER OR
GRANT CONSENT WITH RESPECT TO SHARES HELD BY US FOR YOUR ACCOUNT.
 
    We request instructions as to whether you wish us to tender and/or grant
consent to the Proposal with respect to any or all of the Shares held by us for
your account, upon the terms and subject to the conditions set forth in the
Offer.
 
    PLEASE READ THE FOLLOWING INFORMATION CAREFULLY:
 
    (1)  The Offer is for any and all Shares outstanding as of            ,
1999. The Offer is conditioned upon, among other things, approval of the
Proposal. The Offer for any one Series of Preferred is not conditioned upon a
minimum number of Shares of such Series of Preferred being tendered and is
independent of the Offer for any other Series of Preferred.
 
    (2)  The Offer and withdrawal rights will expire at 12:00 midnight, New York
City time, on            , 1999 unless the Offer is extended with respect to a
Series of Preferred. Your instructions should be forwarded to us in ample time
to permit us to submit a tender and/or consent on your behalf by the Expiration
Date. If you would like to withdraw your Shares that we have tendered or
withdraw a consent that was given, you can withdraw them so long as the Offer
remains open, or at any time after the expiration of forty business days from
the commencement of the Offer, and if such tendered Shares have not been
accepted for payment and with respect to consents, until the Proposal has become
effective.
 
    (3)  Preferred Shareholders who wish to tender their Shares pursuant to the
Offer must submit a duly completed, valid and unrevoked consent to the Proposal.
However, while you must grant a consent to tender Shares, it is not necessary to
tender Shares in order to consent to the Proposal.
 
    (4)  Preferred Shareholders who are the holders of record as of the Record
Date with respect to such Shares and Preferred Shareholders who have obtained an
irrevocable proxy from such holders have the right to grant their consent to the
Proposal regardless of whether they tender their Shares. If, but only if, a
Preferred Shareholder consents to the Proposal with respect to Shares but does
not tender those Shares and the Proposal is approved, the Company will make the
Special Cash Payment to such Preferred Shareholder in an amount equal to $
for each such Share.
 
    (5)  The Company will pay all stock transfer taxes applicable to its
purchase of Shares pursuant to the Offer, subject to Instruction 6 of the Letter
of Transmittal and Consent.
 
    NONE OF THE COMPANY, ITS BOARD OF DIRECTORS NOR ANY OF ITS OFFICERS MAKES
ANY RECOMMENDATION TO ANY PREFERRED SHAREHOLDER AS TO WHETHER TO TENDER SHARES.
EACH PREFERRED SHAREHOLDER MUST MAKE HIS OR HER OWN
 
                                       2

DECISION AS TO WHETHER TO TENDER SHARES AND, IF SO, HOW MANY SHARES TO TENDER.
 
    If you wish to have us tender and/or grant a consent with respect to any or
all of your Shares held by us for your account upon the terms and subject to the
conditions set forth in the Offer, please so instruct us by completing,
executing, detaching and returning to us the instruction form on the detachable
part hereof. An envelope to return your instructions to us is enclosed. If you
authorize tender of your Shares, all such Shares will be tendered unless
otherwise specified on the detachable part hereof. If you authorize consent to
the Proposal with respect to your Shares, consent to the Proposal will be
granted with respect to all such Shares unless otherwise specified. Your
instructions should be forwarded to us in ample time to permit us to submit a
tender and/or grant a consent to the Proposal on your behalf by the Expiration
Date.
 
    The Offer is not being made to, nor will the Company accept tenders from,
owners of Shares in any jurisdiction in which the Offer or its acceptance would
not be in compliance with the laws of such jurisdiction. The Company is not
aware of any jurisdiction where the making of the Offer or the tender of Shares
would not be in compliance with applicable law. If the Company becomes aware of
any jurisdiction where the making of the Offer or if the tender of Shares is not
in compliance with any applicable law, the Company will make a good faith effort
to comply with such law. If, after such good faith effort, the Company cannot
comply with such law, the Offer will not be made to (nor will tenders be
accepted from or on behalf of) the owners of Shares residing in such
jurisdiction. In any jurisdiction in which the securities, blue sky or other
laws require the Offer to be made by a licensed broker or dealer, the Offer will
be deemed to be made on the Company's behalf by one or more registered brokers
or dealers licensed under the laws of such jurisdiction.
