ITEM 5.  OTHER EVENTS.

         On July 18, 1997, CE Electric (NY), Inc., a New York corporation (the
"Purchaser") and a wholly owned subsidiary of CalEnergy Company, Inc., a
Delaware corporation (the "Registrant"), commenced an offer (the "Offer") to
purchase 6,540,670 shares of Common Stock, par value $6.66-2/3 per share
("Shares"), of New York State Electric & Gas Corporation, a New York
corporation (the "Company"), net to the seller in cash, without interest
thereon. The 6,540,670 Shares sought pursuant to the Offer constitute,
together with the Shares currently beneficially owned by the Purchaser,
approximately 9.9% of the Company's outstanding Shares, based on the Company's
public reports. The aggregate consideration payable by the Purchaser with
respect to the Shares to be purchased in the Offer is approximately $160
million. The Offer will expire at 12:00 midnight, New York City time, on
Thursday, August 14, unless the Offer is extended.

         The Offer is not subject to any financing condition. The Offer is
conditioned upon, among other things, (1) there being validly tendered and not
withdrawn prior to the expiration of the Offer that number of Shares which,
together with Shares beneficially owned by the Purchaser and its affiliates,
represents at least 9.9% of the Shares outstanding and (2) the expiration or
termination of all waiting periods imposed by the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended, and the regulations thereunder. The
Offer is also subject to certain other terms and conditions.

         The purpose of the Offer is to enable the Purchaser to acquire the
Shares, which together with the Shares currently beneficially owned by the
Purchaser, will represent 9.9% of the total number of Shares outstanding. In
order for the Purchaser to acquire more than 9.9% of the outstanding Shares,
the Purchaser will be required to obtain certain regulatory approvals,
including approvals from the Public Service Commission of the State of New
York and the Federal Energy Regulatory Commission.

         Following completion of the Offer, the Purchaser intends to seek
regulatory approvals permitting the acquisition and ownership of 100% of the
Common Stock and thereafter to acquire all of the outstanding Shares it does
not then own. In order to make such acquisition, the Purchaser currently
intends, following completion of the Offer, to offer (the "Subsequent Offer")
to acquire all of the Common Stock it does not then own.

         The Subsequent Offer will be subject to a number of conditions to
which the Offer is not subject, including the receipt of all required
regulatory approvals, the availability of financing, the inapplicability of
certain takeover defenses and certain other conditions. As a result of the
regulatory approval requirement, the Purchaser believes that the Subsequent
Offer will not be capable of being consummated for a significant period of
time after it is commenced. The Purchaser expects that the consideration to be
paid in the Subsequent Offer will be higher than the consideration to be paid
in the Offer, but no assurance can be given that the net present value of that
consideration will be higher than the sum of the consideration to be paid in
the Offer plus the net present value of any regular dividends that may be paid
prior to the time the Subsequent Offer can be completed. The consideration to
be paid in the Subsequent Offer may be cash, securities or a combination
thereof.

         CalEnergy and the Purchaser intend to continue their efforts to seek
to negotiate an acquisition agreement with the Company. No assurance can be
given, however, that any such 


                                     -2-
<PAGE>


negotiations will be entered into or successfully completed, or as to the
terms of any agreement that may be reached. If the current Board of Directors
of the Company continues to refuse to negotiate with CalEnergy and the
Purchaser, CalEnergy and the Purchaser plan to take actions to remove and
replace the current Board of Directors either through a consent solicitation
or through a proxy contest.

         On July 18, 1997, the Purchaser filed a Statement on Schedule 14D-1
relating to the Offer with the Securities and Exchange Commission pursuant to
Rule 14d-3 under the Securities Exchange Act of 1934, a copy of which is
attached hereto as Exhibit 99.1. The foregoing description is qualified in its
entirety by reference to the Offer to Purchase, dated July 18, 1997, which
appears as Exhibit (a)(1) to the Schedule 14D-1 and is hereby incorporated by
reference herein.

TO ALL HOLDERS OF SHARES OF COMMON STOCK OF NEW YORK STATE ELECTRIC & GAS 
CORPORATION: 

                                 INTRODUCTION 

   CE Electric (NY), Inc., a New York corporation (the "Purchaser") and a 
wholly owned subsidiary of CalEnergy Company, Inc., a Delaware corporation 
("CalEnergy"), hereby offers to purchase 6,540,670 shares ("Shares") of 
common stock, par value $6.66 2/3 per share (the "Common Stock"), of New York 
State Electric & Gas Corporation, a New York corporation (the "Company"), at 
$24.50 per Share, net to the seller in cash, without interest thereon, upon 
the terms and subject to the conditions set forth in this Offer to Purchase 
and in the related Letter of Transmittal (which together constitute the 
"Offer"). Tendering holders will be entitled to retain the regular 35 cents 
cash dividend payable in August 1997. See Section 14. 

   Tendering shareholders will not be obligated to pay brokerage fees or 
commissions or, except as set forth in Instruction 6 of the Letter of 
Transmittal, stock transfer taxes on the purchase of Shares by the Purchaser 
pursuant to the Offer. The Purchaser will pay all charges and expenses of 
Lehman Brothers Inc. ("Lehman Brothers") and Credit Suisse First Boston 
Corporation ("Credit Suisse First Boston", and together with Lehman Brothers, 
the "Dealer Managers"), IBJ Schroder Bank & Trust Company (the "Depositary") 
and MacKenzie Partners, Inc. (the "Information Agent") incurred in connection 
with the Offer. 

   The $24.50 per Share consideration offered pursuant to the Offer 
represents a premium of approximately 17.4% over the closing price of the 
Common Stock on the New York Stock Exchange, Inc. (the "NYSE") on June 30, 
1997, the day an affiliate of CalEnergy commenced purchases of Common Stock 
in the open market. CalEnergy and its affiliates currently own approximately 
0.35% of the outstanding Common Stock. The Offer is not subject to any 
financing or regulatory approval condition, other than the expiration or 
termination of all waiting periods imposed by the Hart-Scott-Rodino Antitrust 
Improvements Act of 1976, as amended, and the regulations thereunder. 

   As described more fully below, on July 10, 1997, David L. Sokol, the 
Chairman and Chief Executive Officer of CalEnergy met with Wesley W. von 
Schack, the Chairman, Chief Executive Officer and President of the Company to 
discuss the possibility of a business combination between the Company and 
CalEnergy. Subsequent to that meeting, Mr. von Schack called Mr. Sokol to 
inform him that the Board of Directors of the Company, at a meeting on July 
11, 1997, had determined that discussions of this opportunity were not a 
priority and could not be conducted on the timely basis which Mr. Sokol had 
outlined in their meeting. As a result of this decision by the Company's 
Board of Directors, on July 15, 1997, CalEnergy and the Purchaser announced 
their intention to commence the Offer, and on July 18, 1997 CalEnergy and the 
Purchaser commenced the Offer. See Section 10. 

   The purpose of the Offer is to enable the Purchaser to acquire that number 
of Shares which, together with the Shares currently beneficially owned by the 
Purchaser and its affiliates, will represent 9.9% of the total number of 
Shares outstanding. In order for the Purchaser to acquire more than 9.9% of 
the outstanding Shares, the Purchaser will be required to obtain certain 
regulatory approvals, including approvals from the Public Service Commission 
of the State of New York and the Federal Energy Regulatory Commission. See 
Section 15. 

   Following completion of the Offer, the Purchaser intends to seek 
regulatory approvals permitting the acquisition and ownership of 100% of the 
Common Stock and thereafter to acquire all of the outstanding Shares it does 
not then own. See Section 15. In order to make such acquisition, the 
Purchaser currently intends, following completion of the Offer, to offer (the 
"Subsequent Offer") to acquire all of the Common Stock it does not then own. 

   The Subsequent Offer will be subject to a number of conditions to which 
the Offer is not subject, including the receipt of all required regulatory 
approvals, the availability of financing, the inapplicability of certain 
takeover defenses and certain other conditions. As a result of the regulatory 
approval requirement, the Purchaser believes that the Subsequent Offer will 
not be capable of being consummated for a significant period of time after it 
is commenced. See Section 15. The Purchaser expects that the 

<PAGE>

consideration to be paid in the Subsequent Offer will be higher than the 
consideration to be paid in the Offer, but no assurance can be given that the 
net present value of that consideration will be higher than the sum of the 
consideration to be paid in the Offer plus the net present value of any 
regular dividends that may be paid prior to the time the Subsequent Offer can 
be completed. The consideration to be paid in the Subsequent Offer may be 
cash, securities or a combination thereof. 

   CalEnergy and the Purchaser intend to continue their efforts to seek to 
negotiate an acquisition agreement with the Company. No assurance can be 
given, however, that any such negotiations will be entered into or 
successfully completed, or as to the terms of any agreement that may be 
reached. If the current Board of Directors of the Company continues to refuse 
to negotiate with CalEnergy and the Purchaser, CalEnergy and the Purchaser 
plan to take actions to remove and replace the current Board of Directors 
either through a consent solicitation or through a proxy contest. 

   Lehman Brothers and Credit Suisse First Boston have delivered to CalEnergy 
fully underwritten offers to provide the Purchaser with the full amount of 
financing for the Subsequent Offer at a price up to $27.50 per Share. 

   THE OFFER WILL EXPIRE AT 12:00 MIDNIGHT, NEW YORK CITY TIME, ON THURSDAY, 
AUGUST 14, 1997, UNLESS EXTENDED. 

   THE PURCHASER AND ITS AFFILIATES RESERVE THE RIGHT, FOLLOWING COMPLETION 
OR TERMINATION OF THE OFFER AND EITHER PRIOR OR SUBSEQUENT TO OR IN LIEU OF 
THE SUBSEQUENT OFFER, TO ACQUIRE SHARES THROUGH MARKET PURCHASES, PRIVATELY 
NEGOTIATED TRANSACTIONS, A MERGER OR OTHER BUSINESS COMBINATION OR ANY 
COMBINATION OF THE FOREGOING. 

   THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, (1) THERE BEING VALIDLY 
TENDERED AND NOT WITHDRAWN PRIOR TO THE EXPIRATION OF THE OFFER THAT NUMBER 
OF SHARES WHICH, TOGETHER WITH SHARES BENEFICIALLY OWNED BY THE PURCHASER AND 
ITS AFFILIATES, REPRESENTS AT LEAST 9.9% OF THE SHARES OUTSTANDING (THE 
"MINIMUM TENDER CONDITION") AND (2) THE EXPIRATION OR TERMINATION OF ALL 
WAITING PERIODS IMPOSED BY THE HART-SCOTT-RODINO ANTITRUST IMPROVEMENTS ACT 
OF 1976, AS AMENDED, AND THE REGULATIONS THEREUNDER (THE "HSR ACT"). CERTAIN 
OTHER CONDITIONS TO CONSUMMATION OF THE OFFER ARE DESCRIBED IN SECTION 12. 
THE PURCHASER EXPRESSLY RESERVES THE RIGHT TO WAIVE ANY ONE OR MORE OF THE 
CONDITIONS TO THE OFFER. 

   The Minimum Tender Condition. The Minimum Tender Condition requires that 
there be validly tendered and not withdrawn prior to the expiration of the 
Offer that number of Shares which, together with Shares beneficially owned by 
the Purchaser and its affiliates, represents at least 9.9% of the Shares 
outstanding. According to the Company's Quarterly Report on Form 10-Q for the 
fiscal quarter ended March 31, 1997 (the "March 10-Q"), as of April 30, 1997 
there were 68,502,727 Shares outstanding. An affiliate of the Purchaser 
beneficially owns 241,100 Shares, representing, based on information in the 
March 10-Q, approximately 0.35% of the outstanding Shares. Based on the 
foregoing and assuming no repurchases or issuances of Shares, the 6,540,670 
Shares sought pursuant to the Offer, together with the 241,100 Shares held by 
an affiliate of the Purchaser, will satisfy the Minimum Tender Condition. The 
Shares beneficially owned by the Purchaser and CalEnergy were recently 
acquired in open market purchases. See Schedule II. 

   THIS OFFER TO PURCHASE AND THE LETTER OF TRANSMITTAL CONTAIN IMPORTANT 
INFORMATION WHICH SHOULD BE READ CAREFULLY BEFORE ANY DECISION IS MADE WITH 
RESPECT TO THE OFFER.

                               THE TENDER OFFER 

   1. TERMS OF THE OFFER; EXPIRATION DATE; PRORATION. Upon the terms and 
subject to the conditions of the Offer (including, if the Offer is extended 
or amended, the terms and conditions of any extension or amendment), the 
Purchaser will accept for payment and pay for 6,540,670 Shares tendered on or 
before the Expiration Date (as defined below) and not theretofore withdrawn 
in accordance with Section 3. The term "Expiration Date" means 12:00 
Midnight, New York City time, on Thursday, August 14, 1997, unless the 
Purchaser, in its sole discretion, shall have extended the period of time for 
which the Offer is open, in which event the term "Expiration Date" shall mean 
the latest time and date at which the Offer, as so extended by the Purchaser, 
shall expire. 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. 

   If any or all of the conditions set forth in Section 12 are not satisfied 
prior to the Expiration Date, the Purchaser may elect to (i) extend the Offer 
and retain all tendered Shares until the expiration of the Offer, as 
extended, subject to the terms of the Offer (including any rights of 
tendering shareholders to withdraw their Shares), (ii) terminate the Offer 
and not accept for payment any Shares and return all tendered Shares to 
tendering shareholders or (iii) waive any or all conditions and, subject to 
complying with applicable rules and regulations of the Commission, accept for 
payment all Shares validly tendered. The Purchaser reserves the right to 
accept for payment and to pay for more than 6,540,670 Shares pursuant to the 
Offer, although it has no present intention to do so. 

   Upon the terms and subject to the conditions of the Offer, if more than 
6,540,670 Shares (or such greater number of Shares as the Purchaser elects to 
accept for payment and pay for) shall be validly tendered and not withdrawn 
prior to the Expiration Date, the Purchaser will, upon the terms and subject 
to the conditions of the Offer, purchase 6,540,670 Shares (or such greater 
number of Shares) on a pro rata basis (with adjustments to avoid purchases of 
fractional Shares) based upon the number of Shares validly tendered and not 
withdrawn prior to the Expiration Date. If fewer than 6,540,670 Shares are 
validly tendered by the Expiration Date and not withdrawn, the Purchaser may 
(i) terminate the Offer and return all tendered Shares to tendering 
shareholders or (ii) extend the Offer and retain such Shares until the 
expiration of the Offer as extended, subject to the terms of the Offer. The 
Purchaser does not presently intend to waive the condition that at least 
6,540,670 Shares be validly tendered and not withdrawn prior to the 
Expiration Date. However, the Purchaser reserves the right to waive such 
condition. 

   In the event that proration of tendered Shares is required, because of the 
difficulty of determining the precise number of Shares properly tendered and 
not withdrawn, the Purchaser may not be able to announce the final proration 
factor until approximately six NYSE trading days after the Expiration Date. 
Preliminary results of proration will be announced by press release as 
promptly as practicable after the Expiration Date. Shareholders may obtain 
such preliminary information from the Information Agent and may be able to 
obtain such information from their brokers. The Purchaser will not pay for 
any Shares accepted for payment pursuant to the Offer until the final 
proration factor is known. 

   If, as a result of repurchases of outstanding Shares by the Company or for 
any other reason, the purchase by the Purchaser of 6,540,670 Shares pursuant 
to the Offer would cause the Purchaser to own more than 9.9% of the number of 
Shares then outstanding, the number of Shares to be purchased by the 
Purchaser pursuant to the Offer will be reduced by an appropriate number of 
Shares (to be determined by the Purchaser in its sole discretion) so that the 
purchase of Shares by the Purchaser pursuant to the Offer will not cause the 
Purchaser to own more than 9.9% of the number of Shares then outstanding. 

   The Purchaser expressly reserves the right, in its sole judgment, at any 
time or from time to time, and regardless of whether any of the events set 
forth in Section 12 shall have occurred or shall have been determined by the 
Purchaser to have occurred, (i) to extend the period of time during which the 
Offer is open and thereby delay acceptance for payment of, and the payment 
for, any Shares, by giving oral or written notice of such extension to the 
Depositary and (ii) to amend the Offer in any respect by giving oral or 
written notice of such amendment to the Depositary. The rights reserved by 
the Purchaser in this paragraph are in addition to the Purchaser's rights to 
terminate the Offer pursuant to Section 12. Any such extension, amendment or 
termination will be followed as promptly as practicable by public announce- 

                                       3
<PAGE>

ment thereof, such announcement in the case of an extension to be issued not 
later than 9:00 A.M., New York City time, on the next business day after the 
previously scheduled Expiration Date. The manner in which the Purchaser will 
make such public announcement may, if appropriate, be limited to a release to 
the Dow Jones News Service. The reservation by the Purchaser of the right to 
delay acceptance for payment of or payment for any Shares is subject to the 
provisions of applicable law, which require that the Purchaser pay the 
consideration offered or return the Shares deposited by or on behalf of 
shareholders promptly after termination or withdrawal of the Offer. 

   If the Purchaser decides to increase or decrease the consideration offered 
in the Offer, or to increase or decrease the percentage of the outstanding 
number of Shares being sought (other than an increase in the number of Shares 
being sought that does not exceed 2% of the number of Shares outstanding), 
and if at the time that notice of such increase or decrease is first 
published, sent or given to holders of Shares in the manner specified above, 
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 
such notice is first so published, sent or given, the Offer will be extended 
until the expiration of such period of ten business days. If the Purchaser 
waives any material condition to the Offer, or amends the Offer in any other 
material respect, the Purchaser will extend the Offer and disseminate 
additional tender offer materials to the extent required to comply with the 
Commission's interpretation of Rules 14d-4(c) and 14d-6(d) under the Exchange 
Act. The minimum period during which an offer must remain open following 
material changes in the terms of the offer or information concerning the 
offer, other than a change in price or a change in percentage of securities 
sought, will depend upon the facts and circumstances, including the relative 
materiality of the change in terms or information. 

   A request is being made to the Company pursuant to Rule 14d-5 of the 
Exchange Act for use of the Company's shareholder lists and security position 
listings for the purpose of disseminating the Offer to holders of Shares. 
This Offer to Purchase, the related Letter of Transmittal and other relevant 
materials will be mailed to record holders of Shares, and will be furnished 
to brokers, dealers, commercial banks, trust companies and similar persons 
whose names, or the names of whose nominees, appear on the shareholder lists 
or who are listed as participants in a clearing agency's security position 
listing for subsequent transmittal to beneficial owners of Shares by the 
Purchaser following receipt of such lists or listings from the Company, or by 
the Company if it so elects. 

   2. ACCEPTANCE FOR PAYMENT AND PAYMENT FOR SHARES. Upon the terms and 
subject to the conditions of the Offer (including, if the Offer is extended 
or amended, the terms and conditions of any such extension or amendment), the 
Purchaser will accept for payment, and will pay for, 6,540,670 Shares validly 
tendered before the Expiration Date and not properly withdrawn in accordance 
with Section 3 (including Shares validly tendered and not withdrawn during 
any extension of the Offer, if the Offer is extended, subject to the terms 
and conditions of such extension) as soon as practicable after the last to 
occur of (i) the Expiration Date and (ii) the expiration or termination of 
the waiting period under the HSR Act, in connection with the filings to be 
made related to the Offer. In addition, the Purchaser expressly reserves the 
right, in its sole discretion, to delay the acceptance for payment of or 
payment for Shares in order to comply, in whole or in part, with any other 
applicable law. Any such delays will be effected in compliance with Rule 
14e-1(c) under the Exchange Act (relating to the Purchaser's obligation to 
pay for or return tendered Shares promptly after the termination or 
withdrawal of the Offer). 

   The per Share consideration paid to any shareholder pursuant to the Offer 
will be the highest per Share consideration paid to any other shareholder 
pursuant to the Offer. In all cases, payment for Shares accepted for payment 
pursuant to the Offer will be made only after timely receipt by the 
Depositary of (i) certificates for such Shares (or timely confirmation (a 
"Book-Entry Confirmation") of the book-entry transfer of such Shares into the 
Depositary's account at The Depository Trust Company or Philadelphia 
Depository Trust Company (collectively, the "Book-Entry Transfer 
Facilities")), pursuant to the procedures set forth in Section 4, (ii) a 
properly completed and duly executed Letter of Transmittal (or facsimile 
thereof) with any required signature guarantees, or an Agent's Message (as 
defined below) in connection with a book-entry transfer, and (iii) any other 
documents required by the Letter of Transmittal. 

                                       4
<PAGE>

   The term "Agent's Message" means a message, transmitted by a Book-Entry 
Transfer Facility to, and received by, the Depositary and forming a part of a 
Book-Entry Confirmation, which states that such Book-Entry Transfer Facility 
has received an express acknowledgment from the participant in such 
Book-Entry Transfer Facility tendering the Shares, that such participant has 
received and agrees to be bound by the terms of the Letter of Transmittal and 
that the Purchaser may enforce such agreement against the participant. 

   Payment for Shares accepted for payment pursuant to the Offer may be 
delayed in the event of proration due to the difficulty of determining the 
number of Shares validly tendered and not withdrawn. See Section 1. 

   A Notification and Report Form with respect to the Offer was filed under 
the HSR Act on July 17, 1997, and the waiting period with respect to the 
Offer under the HSR Act will expire at 11:59 P.M., New York City time, on 
August 1, 1997. Before such time, however, either the Federal Trade 
Commission (the "FTC") or the Antitrust Division of the Department of Justice 
(the "Antitrust Division") may extend the waiting period by requesting 
additional information or material from the Purchaser. If such request is 
made, the waiting period will expire at 11:59 P.M., New York City time, on 
the tenth calendar day after the Purchaser has substantially complied with 
such request. Thereafter, the waiting period may be extended only by court 
order or with the Purchaser's consent. See Section 15. 

   For purposes of the Offer, the Purchaser will be deemed to have accepted 
for payment, and thereby purchased, Shares properly tendered to the Purchaser 
and not withdrawn, if, as and when the Purchaser gives oral or written notice 
to the Depositary of its acceptance for payment of the tenders of such 
Shares. Payment for Shares accepted for payment pursuant to the Offer will be 
made by deposit of the purchase price therefor with the Depositary, which 
will act as agent for the tendering shareholders for purposes of receiving 
payment from the Purchaser and transmitting payment to tendering 
shareholders. 

   UNDER NO CIRCUMSTANCES WILL THE PURCHASER PAY INTEREST ON THE PURCHASE 
PRICE OF THE SHARES TO BE PAID BY THE PURCHASER, REGARDLESS OF ANY DELAY IN 
MAKING SUCH PAYMENT. 

   Upon the deposit of funds with the Depositary for the purpose of making 
payments to tendering shareholders, the Purchaser's obligation to make such 
payment shall be satisfied and tendering shareholders must thereafter look 
solely to the Depositary for payment of amounts owed to them by reason of the 
acceptance for payment of Shares pursuant to the Offer. 

   If any tendered Shares are not accepted for payment pursuant to the terms 
and conditions of the Offer for any reason or are not paid for because of an 
invalid tender, or if certificates are submitted representing more Shares 
than are tendered, certificates representing unpurchased or untendered Shares 
will be returned, without expense to the tendering shareholder (or, in the 
case of Shares tendered by book-entry transfer of such Shares into the 
Depositary's account at a Book-Entry Transfer Facility as described in 
Section 4, such Shares will be credited to an account maintained within such 
Book-Entry Transfer Facility), as soon as practicable following the 
expiration, termination or withdrawal of the Offer and determination of the 
final results of proration. 

   As required by Commission rules, if the Purchaser were to vary the terms 
of the Offer by increasing the consideration to be paid per Share, the 
Purchaser will pay such increased consideration for all Shares purchased 
pursuant to the Offer, whether or not such Shares have been tendered prior to 
such increase in consideration. 

   The Purchaser reserves the right to transfer or assign, in whole or from 
time to time in part, to one or more direct or indirect subsidiaries of 
CalEnergy, the right to purchase all or any portion of the Shares tendered 
pursuant to the Offer, but any such transfer or assignment will not relieve 
the Purchaser of its obligations under the Offer and will in no way prejudice 
the rights of tendering shareholders to receive payment for Shares validly 
tendered and accepted for payment pursuant to the Offer. 

   3. WITHDRAWAL RIGHTS. Except as otherwise provided in this Section 3, 
tenders of Shares made pursuant to the Offer are irrevocable. Shares tendered 
pursuant to the Offer may be withdrawn at any time before the Expiration Date 
and, unless theretofore accepted for payment by the Purchaser as provided 
herein, may also be withdrawn at any time after September 16, 1997. 

                                       5
<PAGE>

   If, for any reason whatsoever, acceptance for payment of any Shares 
tendered pursuant to the Offer is delayed, or if the Purchaser is unable to 
accept for payment or pay for Shares tendered pursuant to the Offer, then, 
without prejudice to the Purchaser's rights set forth herein, the Depositary 
may, nevertheless, on behalf of the Purchaser and subject to Rule 14e-1(c) 
under the Exchange Act, retain tendered Shares, and such Shares may not be 
withdrawn except to the extent that the tendering shareholder is entitled to 
and duly exercises withdrawal rights as described in this Section 3. Any such 
delay will be accompanied by an extension of the Offer to the extent required 
by law. 

   In order for a withdrawal to be effective, a written, telegraphic or 
facsimile transmission notice of withdrawal must be timely received by the 
Depositary at one of its addresses set forth on the back cover of this Offer 
to Purchase. Any notice of withdrawal must specify the name of the person 
having tendered the Shares to be withdrawn, the number of Shares to be 
withdrawn and, if certificates for Shares have been tendered, the name of the 
registered holder of Shares as set forth in the tendered certificate, if 
different from that of the person who tendered such Shares. If certificates 
for Shares ("Certificates") have been delivered or otherwise identified to 
the Depositary, then, before the physical release of such Certificates, the 
serial numbers shown on such Certificates must be submitted to the Depositary 
and the signatures on the notice of withdrawal must be guaranteed by a firm 
which is a bank, broker, dealer, credit union, savings association or other 
entity which is a member in good standing of the Securities Transfer Agent's 
Medallion Program (collectively, "Eligible Institutions"), unless such Shares 
have been tendered for the account of any Eligible Institution. If Shares 
have been delivered pursuant to the procedures for book-entry delivery as set 
forth in Section 4, any notice of withdrawal must also specify the name and 
the number of the account at the appropriate Book-Entry Transfer Facility to 
be credited with the withdrawn Shares and otherwise comply with such 
Book-Entry Transfer Facility's procedures. Withdrawal of tenders of Shares 
may not be rescinded, and any Shares properly withdrawn will be deemed not to 
be validly tendered for purposes of the Offer. Withdrawn Shares may, however, 
be retendered by repeating one of the procedures described in Section 4 at 
any time before 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 Purchaser, in its sole 
discretion, whose determination shall be final and binding. None of the 
Purchaser, CalEnergy, the Dealer Managers, the Depositary, the Information 
Agent or any other person will be under any duty to give notification of any 
defects or irregularities in any notice of withdrawal or will incur any 
liability for failure to give any such notification. 

   4. PROCEDURE FOR TENDERING SHARES. To tender Shares validly pursuant to 
the Offer, a shareholder must cause a properly completed and duly executed 
Letter of Transmittal (or facsimile thereof), with any required signature 
guarantees, or an Agent's Message in connection with a book-entry delivery of 
Shares and any other required documents, to be received by the Depositary at 
one of its addresses set forth on the back cover of this Offer to Purchase 
and must either cause certificates for tendered Shares to be received by the 
Depositary at one of such addresses or cause such Shares to be delivered 
pursuant to the procedures for book-entry delivery set forth below (and a 
Book-Entry Confirmation to be received by the Depositary), in each case 
before the Expiration Date, or (in lieu of the foregoing) such shareholder 
must comply with the guaranteed delivery procedure set forth below. 

   The Depositary will establish accounts with respect to the Shares at the 
Book-Entry Transfer Facilities for purposes of the Offer within two business 
days after the date of this Offer to Purchase. Any financial institution that 
is a participant in any of the Book-Entry Transfer Facilities' systems may 
make book-entry delivery of the Shares by causing such Book-Entry Transfer 
Facility to transfer such Shares into the Depositary's account in accordance 
with such Book-Entry Transfer Facility's procedure for such transfer. 
However, although delivery of Shares may be effected through book-entry 
transfer into the Depositary's account at a Book-Entry Transfer Facility, the 
Letter of Transmittal (or facsimile thereof), properly completed and duly 
executed, with any required signature guarantees, or an Agent's Message in 
connection with a book-entry delivery of Shares, and any other required 
documents, must, in any case, be transmitted to and received by the 
Depositary at one of its addresses set forth on the back cover of this Offer 
to Purchase before the Expiration Date, or the tendering shareholder must 
comply with the guaranteed delivery procedure described below. 

                                       6
<PAGE>

   DELIVERY OF DOCUMENTS TO A BOOK-ENTRY TRANSFER FACILITY IN ACCORDANCE WITH 
SUCH BOOK-ENTRY TRANSFER FACILITY'S PROCEDURES DOES NOT CONSTITUTE DELIVERY 
TO THE DEPOSITARY. 

   Signatures on all Letters of Transmittal must be guaranteed by an Eligible 
Institution, except in cases where Shares are tendered (i) by registered 
holders of Shares (which term includes any participant in a Book-Entry 
Transfer Facility whose name appears on a security position listing as the 
owner of the Shares) who has not completed either the box entitled "Special 
Payment Instructions" or the box entitled "Special Delivery Instructions" on 
the Letter of Transmittal or (ii) for the account of an Eligible Institution. 
See Instruction 1 of the Letter of Transmittal. If the Certificates are 
registered in the name of a person other than the signer of the Letter of 
Transmittal, or if payment is to be made to a person other than the 
registered owner of the Certificates surrendered, then the Certificates must 
be endorsed or accompanied by duly executed stock powers, in either case 
signed exactly as the name or names of the registered owner or owners appear 
on the Certificates, with the signature(s) on the Certificates or stock 
powers guaranteed as aforesaid. See Instruction 5 of the Letter of 
Transmittal. 

   The method of delivery of Shares, the Letter of Transmittal and any other 
required documents, including delivery through a Book-Entry Transfer 
Facility, is at the option and risk of the tendering shareholder, and 
delivery will be deemed made only when actually received by the Depositary. 
If delivery is by mail, registered mail with return receipt requested, 
properly insured, is recommended. In all cases, sufficient time should be 
allowed to ensure timely delivery. 

   Unless an exemption applies under the applicable law and regulations 
concerning "backup withholding" of federal income tax, the Depositary will be 
required to withhold, and will withhold, 31% of the gross proceeds otherwise 
payable to a shareholder or other payee with respect to Shares purchased 
pursuant to the Offer if the shareholder does not provide his taxpayer 
identification number (social security number or employer identification 
number) and certify that such number is correct. Each tendering shareholder 
should complete and sign the main signature form and the Substitute Form W-9 
included as part of the Letter of Transmittal, so as to provide the 
information and certification necessary to avoid backup withholding, unless 
an applicable exemption exists and is proved in a manner satisfactory to the 
Purchaser and the Depositary. 

   If a shareholder desires to tender Shares pursuant to the Offer and such 
shareholder's Certificates are not immediately available or such shareholder 
cannot deliver the Certificates and all other required documents to the 
Depositary before the Expiration Date, such Shares may nevertheless be 
tendered, provided that all of the following conditions are satisfied: 

     (a) such tender is made by or through an Eligible Institution; and 

     (b) a properly completed and duly executed Notice of Guaranteed Delivery, 
    substantially in the form provided by the Purchaser, is received by the 
    Depositary, as provided below, on or before the Expiration Date; and 

     (c) the certificates for all tendered Shares, in proper form for transfer 
    (or a Book-Entry Confirmation), together with a properly completed and 
    duly executed Letter of Transmittal (or facsimile thereof) with any 
    required signature guarantees (or, in the case of a book-entry transfer, 
    an Agent's Message) and all other documents required by the Letter of 
    Transmittal are received by the Depositary within three NYSE trading days 
    after the date of execution of such Notice of Guaranteed Delivery to the 
    Depositary. 

   The Notice of Guaranteed Delivery may be delivered by hand or transmitted 
by telegram, facsimile transmission or mail to the Depositary and must 
include a guarantee by an Eligible Institution in the form set forth in the 
Notice of Guaranteed Delivery. 

   In all cases, payment for Shares tendered and accepted for payment 
pursuant to the Offer will be made only after timely receipt by the 
Depositary of (i) Certificates, or a Book-Entry Confirmation of such Shares, 
(ii) a properly completed and duly executed Letter of Transmittal (or 
facsimile thereof) (or, in the 

                                       7
<PAGE>

case of a book-entry transfer, an Agent's Message) and (iii) any other 
documents required by the Letter of Transmittal. Accordingly, payment might 
not be made to all tendering shareholders at the same time, and will depend 
upon when Certificates or Book-Entry Confirmations of such Shares are 
received by the Depositary. 

   By executing a Letter of Transmittal as set forth above, the tendering 
shareholder irrevocably appoints designees of the Purchaser, and each of 
them, as his attorneys-in-fact and proxies, in the manner set forth in the 
Letter of Transmittal, each with full power of substitution, to the full 
extent of such shareholder's rights with respect to the Shares tendered by 
such shareholder and accepted for payment by the Purchaser and with respect 
to any and all other Shares or other securities issued or issuable in respect 
of such Shares on or after the date of this Offer to Purchase. All such 
powers of attorney and proxies shall be considered irrevocable and coupled 
with an interest in the tendered Shares. Such appointment will be effective 
when, and only to the extent that, the Purchaser accepts such Shares for 
payment. Upon such appointment, all prior proxies given by such shareholder 
will be revoked, and no subsequent proxies may be given by such shareholder 
(and if given, will not be deemed effective). The Purchaser's designees will 
be empowered, among other things, to exercise all voting and other rights of 
such shareholder as they in their sole discretion may deem proper at any 
annual, special or adjourned meeting of the shareholders of the Company or 
any consent in lieu of any such meeting or otherwise. The Purchaser reserves 
the right to require that, in order for the Shares to be deemed validly 
tendered, immediately upon the Purchaser's acceptance for payment of such 
Shares, the Purchaser must be able to exercise full voting and other rights 
of a record and beneficial holder, including acting by written consent, with 
respect thereto. 

   All questions as to the validity, form, eligibility (including time of 
receipt) and acceptance for payment of any tender of Shares will be 
determined by the Purchaser, in its sole discretion, whose determination 
shall be final and binding. The Purchaser reserves the absolute right to 
reject any and all tenders determined by it not to be in proper form or the 
acceptance for payment of which may, in the opinion of its counsel, be 
unlawful. The Purchaser also reserves the absolute right to waive any of the 
conditions of the Offer or any defect or irregularity in the tender of any 
Shares of any particular shareholder whether or not similar defects or 
irregularities are waived in the case of other shareholders. None of the 
Purchaser, CalEnergy, the Depositary, the Dealer Managers, the Information 
Agent or any other person will be under any duty to give notification of any 
defects or irregularities in tenders or shall incur any liability for failure 
to give any such notification. The Purchaser's interpretation of the terms 
and conditions of the Offer (including the Letter of Transmittal and of the 
instructions thereto) will be final and binding. 

   The valid tender of Shares pursuant to one of the procedures described 
above will constitute the tendering shareholder's acceptance of the terms and 
conditions of the Offer. The Purchaser's acceptance for payment of Shares 
tendered pursuant to the Offer will constitute a binding agreement between 
the tendering shareholder and the Purchaser upon the terms and subject to the 
conditions of the Offer. 

   5. CERTAIN FEDERAL INCOME TAX CONSEQUENCES. The following summary is a 
general discussion of the material federal income tax consequences to 
shareholders of the Company who tender their Shares pursuant to the Offer. 
The discussion is based upon the Internal Revenue Code of 1986, as amended 
(the "Code"), applicable Treasury regulations thereunder, administrative 
procedures, rulings and decisions in effect on the date hereof, all of which 
are subject to change (possibly with retroactive effect) by legislation, 
administrative action or judicial decision. No ruling has or will be 
requested from the Internal Revenue Service (the "Service") regarding the 
anticipated tax consequences described herein. The discussion set forth below 
does not discuss all aspects of federal income taxation that may be relevant 
to a particular shareholder in light of his personal investment circumstances 
or to certain types of shareholders subject to special treatment under the 
federal income tax laws (for example, tax-exempt organizations, foreign 
corporations and individuals who have received Shares as compensation or who 
are not citizens or residents of the United States) and does not discuss any 
aspect of state, local or foreign taxation. The discussion is limited to 
those shareholders who hold the Shares as capital assets (generally, property 
held for investment) within the meaning of Section 1221 of the Code. 

   SHAREHOLDERS SHOULD CONSULT THEIR INDIVIDUAL TAX ADVISORS CONCERNING THE 
SPECIFIC TAX CONSEQUENCES OF THE OFFER, INCLUDING THE APPLICATION AND EFFECT 
OF STATE, LOCAL, FOREIGN AND OTHER TAX LAWS. 

                                       8
<PAGE>

   Exchange of Shares for Cash. The exchange of Shares by tendering 
shareholders will be a taxable event for federal income tax purposes, and may 
also be a taxable transaction under applicable state, local and foreign tax 
laws. A tendering shareholder will generally recognize gain or loss equal to 
the difference between the amount of cash received by the shareholder 
pursuant to the Offer and the aggregate tax basis in the Shares tendered by 
the shareholder and purchased pursuant to the Offer. Gain or loss will be 
calculated separately for each block of Shares tendered by the shareholder 
and purchased pursuant to the Offer. 

   Gain or loss recognized by a tendering shareholder will be capital gain or 
loss if the Shares are held as capital assets. Such capital gain or loss will 
be classified as a long-term capital gain or loss to the extent that the 
tendered Shares have a holding period of more than one year at the time of 
their purchase pursuant to the Offer. Long-term capital gains recognized by a 
tendering individual shareholder will be subject to tax at a maximum marginal 
federal rate of 28%. Short-term capital gains recognized by a tendering 
individual shareholder will be subject to tax at a maximum marginal federal 
rate of 39.6%. Net capital gains recognized by a tendering corporate 
shareholder will be subject to tax at a maximum marginal federal rate of 35%. 

   Backup Withholding. To prevent "backup withholding" of federal income tax 
on payments of cash to a shareholder of the Company who exchanges Shares for 
cash in the Offer, a shareholder of the Company must, unless an exception 
applies under the applicable law and regulations, provide the payor of such 
cash with such shareholder's correct taxpayer identification number ("TIN") 
on a Substitute Form W-9 and certify under penalties of perjury that such 
number is correct and that such shareholder is not subject to backup 
withholding. A Substitute Form W-9 is included in the Letter of Transmittal. 
If the correct TIN and certifications are not provided, a $50 penalty may be 
imposed on a shareholder of the Company by the Service, and cash received by 
such shareholder in exchange for Shares in the Offer may be subject to backup 
withholding at the rate of 31%. Amounts paid as backup withholding do not 
constitute an additional tax and would be allowable as a credit against the 
shareholder's federal income tax liability. 

   6. PRICE RANGE OF SHARES; DIVIDENDS. The Shares are quoted on the NYSE. 
The following table sets forth, for the periods indicated, the reported high 
and low sales prices per Share, and the amount of cash dividends paid per 
Share for each such period. The information for the fiscal years ended 
December 31, 1994, December 31, 1995 and December 31, 1996 is derived from 
the Company's Annual Reports on Form 10-K for the fiscal years ended December 
31, 1995 and December 31, 1996. The information for subsequent periods is 
derived from information reported in published financial sources.

   On July 14, 1997, the last full trading day prior to CalEnergy's issuance 
of the press release announcing its intention to commence the Offer, the 
reported closing sale price per Share on the NYSE was $21.38. The Offer 
represents a 14.6% premium over the reported closing sale price per Share on 
July 14, 1997. 

   SHAREHOLDERS ARE URGED TO OBTAIN A CURRENT MARKET QUOTATION FOR THE 
SHARES. 

   7. EFFECT OF THE OFFER ON THE MARKET FOR THE SHARES AND EXCHANGE ACT 
REGISTRATION. Although the purchase of the Shares pursuant to the Offer will 
reduce the number of Shares that might otherwise trade publicly and may 
reduce the number of holders of Shares, the Purchaser does not believe that 
the purchase of the Shares will significantly affect the liquidity and market 
value of the remaining Shares held by persons other than the Purchaser and 
its affiliates. 

   8. CERTAIN INFORMATION CONCERNING THE COMPANY. According to the Company's 
Annual Report on Form 10-K for the fiscal year ended December 31, 1996 (the 
"1996 10-K"), the Company is a New York corporation with its principal 
executive offices located at Dryden Road, P.O. Box 3287, Ithaca, New York 
14852-3287. According to the 1996 10-K, the Company is primarily engaged in 
generating, purchasing, transmitting and distributing electricity and 
purchasing, transporting and distributing natural gas. 

   Set forth below is certain summary consolidated financial information with 
respect to the Company derived from the information contained in the 1996 
10-K and the March 10-Q. More comprehensive financial information is included 
in reports and other documents filed with the Commission, and the following

   9. CERTAIN INFORMATION CONCERNING THE PURCHASER AND CALENERGY. CalEnergy, 
together with its subsidiaries, is a United States-based global power company 
which generates, distributes and supplies electricity to utilities, 
government entities, retail customers and other customers located throughout 
the world. CalEnergy, through its subsidiaries, is primarily engaged in the 
development, ownership and operation of environmentally responsible 
independent power production facilities worldwide utilizing geothermal 
resources, natural gas and hydroelectric or other energy sources, such as oil 
and coal. In addition, through its U.K. subsidiary, Northern Electric plc 
("Northern"), a regional U.K. electric utility, CalEnergy is engaged in the 
distribution and supply of electricity in an area in northeast England that 
covers approximately 14,400 square kilometers with a population of 
approximately 3.2 million people as well as the generation and supply of 
electricity (together with other related business activities) in other 
regions in England and Wales. CalEnergy believes that its experience in 
operating a regional U.K. utility in the deregulated U.K. marketplace will 
strengthen its ability to compete successfully in the United States, where 
CalEnergy believes that the impending deregulation of the power markets will 
reflect many aspects of the United Kingdom model for competitive generation, 
transmission, distribution and supply of energy. For the year ended December 
31, 1996 and the three months ended March 31, 1997, CalEnergy had total 
revenues of $576.2 million and $566.0 million, respectively, and net income 
of $92.5 million and $27.4 million, respectively. As of March 31, 1997, 
CalEnergy had cash and short-term investments of $335.3 million (not 
including restricted cash and joint venture cash and investments). 

   The principal executive offices of the Purchaser and CalEnergy are located 
at 302 South 36th Street, Suite 400, Omaha, Nebraska 68131 and their 
telephone number is (402) 341-4500. The Purchaser is a wholly owned 
subsidiary of CalEnergy and has not conducted any business except in 
connection with the Offer. The Purchaser was incorporated in 1997 under the 
laws of the State of New York.

   10. BACKGROUND OF THE OFFER; CONTACTS WITH THE COMPANY. On July 10, 1997, 
David L. Sokol, the Chairman and Chief Executive Officer of CalEnergy met 
with Wesley W. von Schack, the Chairman, Chief Executive Officer and 
President of the Company to discuss the possibility of a business combination 
between the Company and CalEnergy. At the meeting, Messrs. Sokol and von 
Schack discussed their views on the electric and gas utility industry in the 
State of New York and elsewhere and the present and future federal and New 
York State regulatory environment. Mr. Sokol indicated that CalEnergy was 
interested in acquiring the Company, and the two explored in general terms 
the feasability of such a transaction, the possibility of a merger of equals 
between the two companies and the benefits to the two companies and their 
shareholders of a business combination. Although no offers to buy or sell 
were made, Messrs. Sokol and von Schack discussed generally the consideration 
that might be paid in a transaction, if such a transaction were to be 
mutually agreeable. Mr. von Schack indicated in this conceptual discussion 

                                       12
<PAGE>

that in his view up to a 25% premium for the Company's shares might be 
appropriate in the context of a stock for stock merger of the Company and 
CalEnergy. Mr. Sokol indicated that if CalEnergy were to acquire the Company 
in a "friendly" transaction, and if certain assumptions regarding the 
Company's business were confirmed (including the assumption that certain 
pending regulatory matters could be resolved favorably), CalEnergy might 
consider making a cash offer of up to $28 per share of Common Stock (and Mr. 
Sokol further indicated that he believed any price near the top end of that 
range would be fully priced). Mr. von Schack indicated to Mr. Sokol that the 
Company's Board of Directors was scheduled to meet the next day, that he 
would bring this discussion to the attention of the Board and that he would 
advise Mr. Sokol as to the Board's reaction. 

   On July 12, 1997, Mr. von Schack called Mr. Sokol to inform him that the 
Board of Directors of the Company, at a meeting on July 11, 1997, had 
determined that discussions concerning a business combination with CalEnergy 
were not a priority and could not be conducted on the timely basis which Mr. 
Sokol had outlined in their meeting. 

   On July 15, 1997, Mr. Sokol delivered to Mr. von Schack and the Company's 
Board the following letter and announced the same by press release: 

     July 15, 1997 

     BY HAND AND VIA FAX 

     Mr. Wesley W. von Schack 
     Chairman, President & Chief Executive Officer 
     New York State Electric & Gas Corporation 
     Binghamton, New York 13902-3607 
     Fax: 607-729-3318 

     Dear Wes: 

     I was disappointed to learn from you in our telephone call on Saturday, 
     July 12th of your Board's decision that pursuing discussions with us 
     concerning the advantages of a possible combination of New York State 
     Electric & Gas Corporation ("NYSEG") and CalEnergy Company, Inc. 
     ("CalEnergy") was not a priority and could not be conducted on the 
     timely basis which I outlined to you in our meeting last week, on 
     Thursday, July 10th. I might add that your Board's reaction does not 
     appear to be consistent with the clear impression you gave me in our 
     meeting last Thursday to the effect that a sale of NYSEG in the price 
     range we conceptually discussed was an alternative that you would 
     seriously and promptly consider and that you agreed it was in the best 
     interests of your shareholders that you do so. 

     Accordingly, after considered review of the publicly available 
     information concerning NYSEG, the CalEnergy Board has concluded that the 
     potential strategic and financial benefits to our companies' 
     shareholders and other concerned constituencies are compelling and 
     should be pursued on an immediate and serious basis. Our strong 
     preference would be to work together with you and the NYSEG Board to 
     complete a negotiated transaction. However, in light of the confusing 
     messages we have received from you and your Board, CalEnergy is today 
     approaching your shareholders directly and announcing a cash tender 
     offer to acquire for $24.50 per share that number of shares of NYSEG 
     common stock which, together with the shares of NYSEG common stock which 
     CalEnergy presently owns, will represent 9.9% of the total number of 
     shares of NYSEG common stock outstanding. Holders tendering their shares 
     will also be entitled to retain the regular 35 cents dividend payable in 
     August. This tender offer is the first step in the intended acquisition 
     of 100% of NYSEG's common shares by CalEnergy. 

     As previously noted, we would much prefer to work together with you and 
     your Board to achieve a negotiated transaction. Accordingly, this letter 
     sets forth a specific proposal for consideration by you and your Board, 
     together with a brief reiteration of the merger rationale which I shared 
     with you at our meeting last week. 

                                       13
<PAGE>

     Our specific merger proposal is to commence negotiations immediately to 
     enter into a consensual merger in which each outstanding share of NYSEG 
     common stock would be exchanged for $27.50 in cash. This cash price 
     represents a premium of 31.74% above the NYSEG $20 7/8 per share NYSE 
     closing price on June 30, 1997 (the day immediately preceding the day on 
     which we first commenced our open market purchases of NYSEG Common 
     Stock). I would also note that the cash merger price which we propose 
     exceeds the up to 25% premium for NYSEG Common Stock which you 
     indicated, in our conceptual discussion during our meeting last 
     Thursday, might be appropriate in the context of a stock for stock 
     merger of NYSEG and CalEnergy. 

     As I informed you in our meeting last week, we have reviewed the 
     regulatory issues in detail and have fully underwritten financing offers 
     in an amount sufficient to complete the acquisition of 100% of NYSEG's 
     common stock at the price set forth above. The difference between our 
     proposed consensual merger price and our partial tender offer price 
     reflects the shorter time interval and increased certainty associated 
     with the purchase of 9.9% of NYSEG's common shares. The partial tender 
     offer requires no regulatory approvals other than expiration of the 
     expected 15-day Hart-Scott-Rodino waiting period, as compared to the 
     estimated nine to twelve months for the regulatory approvals required to 
     complete the acquisition of 100% of NYSEG's common stock. 

     While NYSEG clearly possesses many strengths, you have publicly 
     acknowledged that both New York's energy industry generally and NYSEG 
     specifically face a number of serious, complex and immediate challenges. 
     These include: 

     o  The New York Public Service Commission's restructuring proceedings 
     with respect to, among other things, (i) the lowering of the rates 
     chargeable by NYSEG and other New York utilities, (ii) the potential 
     divestiture of generation assets and (iii) the introduction of broadened 
     competition; 

     o  Litigation by NYSEG concerning the unimplemented rate increases 
     approved in NYSEG's last rate case (August 1995); 

     o  NYSEG's potentially strandable above-market costs (which you have 
     publicly stated are more than twice the national average); 

     o  NYSEG's flat revenues over the last two years; and 

     o  The consistent underperformance of NYSEG's common stock since NYSEG 
     cut its dividend in October 1994. 

     CalEnergy welcomes the deregulation of the New York electric market and 
     views increased competition as positive and beneficial to ratepayers and 
     the larger New York community alike. We would expect to bring a helpful 
     competitive focus to NYSEG's transition to such an environment and in 
     meeting the competitive challenges which it faces. 

     CalEnergy, which has (according to analysts' consensus estimates) 
     expected 1997 revenues in excess of $2 billion, traces its roots to the 
     introduction of the competitive electric generation industry within the 
     United States and has expanded and thrived in the competitive 
     marketplace, both within the U.S. and internationally. 

     As I described to you, CalEnergy's U.K. utility subsidiary, Northern 
     Electric plc (which is engaged in the distribution and supply of 
     electricity to approximately 1.5 million customers, primarily in 
     Northeast England), brings us direct experience, systems and skills 
     acquired in the deregulated and competitive U.K. electric and gas 
     markets. We anticipate using these skills and working closely with the 
     New York Public Service Commission to provide rate reductions for all 
     NYSEG customers following the proposed merger, while maintaining the 
     safe and reliable service to which they are accustomed. 

     Consistent with CalEnergy's decentralized regional organization, we 
     would intend to maintain NYSEG as a separate operating business unit 
     with its existing corporate headquarters. We would also plan to 
     reincorporate CalEnergy in New York and grow NYSEG's business by 
     participating aggressively in the increasingly competitive New York 
     electric market. This would ultimately make a significant contri- 

                                       14
<PAGE>

     bution to the local region's long-term ability to retain jobs and 
     attract new jobs and businesses. CalEnergy is a high growth company 
     which has increased its number of employees tenfold over the past 5 
     years and provides worldwide opportunities in its numerous locations. 

     As I have previously detailed, we believe that our cash merger proposal, 
     which reflects a substantial premium over NYSEG's current market value, 
     represents a full and fair price for your shareholders. Moreover, our 
     proposal would permit your shareholders to realize this substantial cash 
     value notwithstanding the significant uncertainties facing NYSEG and its 
     business today. To the extent that you believe that your shareholders 
     would view favorably an option to receive CalEnergy shares or other 
     forms of consideration in lieu of the cash price we have proposed, we 
     would be willing to consider that in the context of a negotiated 
     transaction. 

     Although we have found it necessary to go directly to your shareholders 
     with our partial tender offer and advise them of our merger proposal, my 
     continuing preference is to pursue this opportunity on a consensual 
     basis with you and NYSEG's board. We are available to meet with you 
     immediately to discuss the terms of this proposal. However, if you 
     choose not to enter into discussions with us, we believe, and we hope 
     you will agree, that NYSEG's Board ought to permit NYSEG's shareholders 
     to freely decide for themselves on the merits of our offer rather than 
     taking any action which would hinder the shareholders' ability to 
     express their views. 

     I look forward to hearing from you soon. 

     Sincerely, 

     /s/David L. Sokol 
     David L. Sokol 
     Chairman & Chief Executive Officer 

     cc: Board of Directors of NYSEG 
         c/o Mr. Wesley W. von Schack 

   On July 15, 1997, CalEnergy and the Purchaser announced their intention to 
commence the Offer, and on July 18, 1997, CalEnergy and the Purchaser 
commenced the Offer. 

   11. PURPOSE OF THE OFFER. 

   General. The purpose of the Offer is to enable the Purchaser to acquire 
the Shares, which together with the Shares currently beneficially owned by 
the Purchaser, will represent 9.9% of the total number of Shares outstanding. 
In order for the Purchaser to acquire more than 9.9% of the outstanding 
Shares of the Company, the Purchaser will be required to obtain certain 
regulatory approvals, including approvals from the PSC and the FERC. See 
Section 15. 

   Following completion of the Offer, the Purchaser intends to seek 
regulatory approvals permitting the acquisition and ownership of 100% of the 
Common Stock and thereafter to acquire all of the outstanding Shares it does 
not then own. See Section 15. In order to make such acquisition, the 
Purchaser currently intends, following completion of the Offer, to make the 
Subsequent Offer to acquire all of the Common Stock it does not then own. 

   The Subsequent Offer will be subject to a number of conditions to which 
the Offer is not subject, including the receipt of all required regulatory 
approvals, the availability of financing, the inapplicability of certain 
takeover defenses and certain other conditions. As a result of the regulatory 
approval requirement, the Purchaser believes that the Subsequent Offer will 
not be capable of being consummated for a significant period of time after it 
is commenced. See Section 15. The Purchaser expects that the consideration to 
be paid in the Subsequent Offer will be higher than the consideration to be 
paid in the Offer, but no assurance can be given that the net present value 
of that consideration will be higher than the sum of the consideration to be 
paid in the Offer plus the net present value of any regular dividends that 
may be paid prior to the time the Subsequent Offer can be completed. The 
consideration to be paid in the Subsequent Offer may be cash, securities or a 
combination thereof. The Purchaser and its affiliates 

                                       15

reserve the right, following completion or termination of the Offer and 
either prior or subsequent to or in lieu of the Subsequent Offer, to acquire 
Shares through market purchases, privately negotiated transactions, a merger 
or other business combination or any combination of the foregoing. 

   CalEnergy and the Purchaser intend to continue their efforts to seek to 
negotiate an acquisition agreement with the Company. If the current Board of 
Directors of the Company continues to refuse to negotiate with CalEnergy and 
the Purchaser, CalEnergy and the Purchaser plan to take actions to remove and 
replace the current Board of Directors either through a consent solicitation 
or through a proxy contest. 

   Lehman Brothers and Credit Suisse First Boston have delivered to CalEnergy 
fully underwritten offers to provide the Purchaser with the full amount of 
financing for the Subsequent Offer at a price up to $27.50 per Share. 

   In the event that following consummation of the Offer the Purchaser does 
not obtain the regulatory approvals permitting the acquisition and ownership 
of 100% of the Common Stock, the Purchaser may seek to sell Shares owned by 
it through market sales or privately negotiated transactions. A sale by the 
Purchaser of a substantial portion of its Shares following consummation of 
the Offer could adversely affect the market value of the Common Stock. 

   Except as indicated in this Offer to Purchase, the Purchaser has no 
present plans or proposals which relate to or would result in an 
extraordinary corporate transaction, such as a merger, reorganization, 
liquidation, relocation of operations, or sale or transfer of assets, 
involving the Company or any of its subsidiaries, or any material changes in 
the Company's corporate structure or business or the composition of the 
Company's Board or the Company's management or personnel. 

   12. CERTAIN CONDITIONS OF THE OFFER. Notwithstanding any other provision 
of the Offer, and in addition to, and not in limitation of, the Purchaser's 
rights to amend the Offer in any respect at any time in its sole discretion, 
the Purchaser shall not be required to accept for payment or pay for, or may 
delay the acceptance for payment of or payment for, tendered Shares (subject 
to Rule 14e-1(c) under the Exchange Act), or may, in the sole discretion of 
the Purchaser, terminate the Offer as to any Shares not then paid for if (i) 
at or before the Expiration Date the Minimum Tender Condition shall not have 
been satisfied or (ii) on or after the date of this Offer to Purchase, and at 
or before the time of payment for any of such Shares, any of the following 
events shall occur or shall be determined by CalEnergy or the Purchaser to

    or seeking to make illegal, to delay or otherwise directly or indirectly 
    to restrain or prohibit the making of the Offer, the acceptance for

    any other affiliates of CalEnergy of a merger or other business 
    combination with the Company, seeking to obtain material damages or 
    otherwise directly or indirectly relating to the transactions contemplated 
    by the Offer or any such merger or business combination, (ii) seeking to 
    prohibit the ownership or operation by CalEnergy, the Purchaser or any 
    other affiliates of CalEnergy of all or any portion of the business or 
    assets of the Company and its subsidiaries or of the Purchaser, or to 
    compel CalEnergy, the Purchaser or any other affiliates of CalEnergy to 
    dispose of or hold separately all or any portion of the business or assets 
    of the Purchaser or the Company or any of its subsidiaries or seeking to 
    impose any limitation on the ability of CalEnergy, the Purchaser or any 
    other affiliates of CalEnergy to conduct their business or own such 
    assets, (iii) seeking to impose or confirm limitations on the ability of 
    CalEnergy, the Purchaser or any other affiliates of CalEnergy effectively 
    to exercise full rights of ownership of the Shares, including, without 
    limitation, the right to vote any Shares acquired by any such person on 
    all matters properly presented to the Company's shareholders, (iv) seeking 
    to require divestiture by CalEnergy, the Purchaser or any other affiliates 
    of CalEnergy of any Shares, (v) otherwise directly or indirectly relating 
    to the Offer or which otherwise, in the sole judgment of the Purchaser, 
    might materially adversely affect CalEnergy, the Purchaser or any other 
    affiliates of 

                                       16
<PAGE>

    CalEnergy or the value of the Shares, or (vi) in the sole judgment of the 
    Purchaser, materially adversely affecting the business, properties, 
    assets, liabilities, capitalization, shareholders' equity, condition 
    (financial or other), operations, licenses or franchises, results of 
    operations or prospects of the Company or any of its subsidiaries, joint 
    ventures or partnerships; provided that the condition specified in this 
    paragraph (a) shall not be deemed to exist by reason of any court 
    proceeding pending on the date hereof and known to the Purchaser, unless 
    in the sole judgment of the Purchaser there is any adverse development in 
    any such proceeding after the date hereof, or before the date hereof if 
    not known to the Purchaser on the date hereof, which might, directly or 
    indirectly, result in any of the consequences referred to in clauses (i) 
    through (vi) above; 

     (b) there shall be any action taken, or any statute, rule, regulation, 
    interpretation, judgment, order or injunction proposed, enacted, enforced, 
    promulgated, amended, issued or deemed applicable (i) to the Purchaser, 
    CalEnergy or any affiliate of CalEnergy or (ii) to the Offer or any 
    business combination by the Purchaser or any affiliate of CalEnergy with 
    the Company, by any court, government or governmental, administrative or 
    regulatory authority or agency, domestic or foreign, other than the 
    routine application of the waiting period provisions of the HSR Act to the 
    Offer or to any business combination, which, in the sole judgment of the 
    Purchaser, might, directly or indirectly, result in any of the 
    consequences referred to in clauses (i) through (vi) of paragraph (a) 
    above; 

     (c) any change (or any condition, event or development involving a 
    prospective change) shall have occurred or been threatened in the 
    business, properties, assets, liabilities, capitalization, shareholders' 
    equity, condition (financial or other), operations, licenses, franchises, 
    permits, permit applications, results of operations or prospects of the 
    Company or any of its subsidiaries which, in the sole judgment of the 
    Purchaser, is or may be materially adverse, or the Purchaser shall have 
    become aware of any fact which, in the sole judgment of the Purchaser, has 
    or may have material adverse significance with respect to either the value 
    of the Company or any of its subsidiaries or the value of the Shares to 
    the Purchaser; 

     (d) there shall have occurred (i) any general suspension of trading in,

    exchange or in the over-the-counter market, or any material adverse change 
    in prices generally of shares on the NYSE or the Nasdaq Stock Market, (ii) 
    a declaration of a banking moratorium or any suspension of payments in 
    respect of banks by federal or state authorities in the United States, 
    (iii) any limitation (whether or not mandatory) by any governmental

    national or international calamity directly or indirectly involving the 
    United States, (v) a material change in United States or any other 
    currency exchange rates or a suspension of, or limitation on, the markets 
    therefor, or (vi) in the case of any of the foregoing existing at the time 
    of the commencement of the Offer, a material acceleration or worsening 
    thereof; 

     (e) the Company or any of its subsidiaries, joint ventures or 
    partnerships or other affiliates shall have (i) split, combined or 
    otherwise changed, or authorized or proposed the split, combination or 
    other change of the Shares or its capitalization, (ii) acquired or 
    otherwise caused a reduction in the number of, or authorized or proposed 
    the acquisition or other reduction in the number of, any presently 
    outstanding Shares or other securities or other equity interests, (iii) 
    issued, distributed or sold, or authorized or proposed the issuance, 
    distribution or sale of, additional Shares, other than Shares issued or

    thereof) of employee stock options outstanding on the date of this Offer 
    to Purchase, shares of any other class of capital stock or other equity

    covenants or security provisions, (vii) authorized, recommended, proposed

    business, (viii) authorized, recommended, proposed or entered into, or 
    announced its intention to authorize, recommend, propose or enter into, 
    any agreement or arrangement with any person or group that in the 
    Purchaser's sole opinion could adversely affect either the value of the 
    Company or any of its subsidiaries, joint ventures or partnerships or the 
    value of the Shares to the Purchaser, (ix) entered into any employment, 
    change in control, severance, executive compensation or similar agreement, 
    arrangement or plan with or for one or more of its employees, consultants

    pursuant to, any agreements, arrangements or plans so as to provide for 
    increased benefits to one or more employees, consultants or directors, or 
    taken any action to fund, secure or accelerate the funding of compensation 
    or benefits provided for one or more employees, consultants or directors, 
    whether or not as a result of or in connection with the transactions 
    contemplated by the Offer, (x) except as may be required by law, taken any 
    action to terminate or amend any employee benefit plan (as defined in 
    Section 3(3) of the Employee Retirement Income Security Act of 1974, as 
    amended) of the Company or any of its subsidiaries, or the Purchaser shall 
    have become aware of any such action which was not previously disclosed in 
    publicly available filings, or (xi) amended or authorized or proposed any 
    amendment to its certificate of incorporation or Bylaws or similar 
    organizational documents, or the Purchaser shall become aware that the 
    Company or any of its subsidiaries shall have proposed or adopted any such 
    amendment which shall not have been previously disclosed; 

     (f) a tender or exchange offer for any Shares shall have been made or 
    publicly proposed to be made by any other person (including the Company or 
    any of its subsidiaries or affiliates), or it shall have been publicly 
    disclosed or the Purchaser shall have otherwise learned that (i) any 
    person, entity (including the Company or any of its subsidiaries) or 
    "group" (within the meaning of Section 13(d)(3) of the Exchange Act) shall 
    have acquired or proposed to acquire beneficial ownership of more than 5% 
    of any class or series of capital stock of the Company (including the 
    Shares), through the acquisition of stock, the formation of a group or 
    otherwise, or shall have been granted any right, option or warrant, 
    conditional or otherwise, to acquire beneficial ownership of more than 5% 
    or any class or series of capital stock of the Company (including the 
    Shares) other than acquisitions for bona fide arbitrage purposes only and 
    except as disclosed in a Schedule 13D or 13G on file with the Commission 
    on the date of this Offer to Purchase, (ii) any such person, entity or 
    group which before the date of this Offer to Purchase had filed such a 
    Schedule with the Commission has acquired or proposes to acquire, through 
    the acquisition of stock, the formation of a group or otherwise, 
    beneficial ownership of 1% or more of any class or series of capital stock 
    of the Company (including the Shares), or shall have been granted any 
    right, option or warrant, conditional or otherwise, to acquire beneficial 
    ownership of 1% or more of any class or series of capital stock of the 
    Company (including the Shares), (iii) any person or group shall have 
    entered into a definitive agreement or an agreement in principle or made a 
    proposal with respect to a tender offer or exchange offer or a merger, 
    consolidation or other business combination with or involving the Company, 
    or (iv) any person shall have filed a Notification and Report Form under 
    the HSR Act or made a public announcement reflecting an intent to acquire 
    the Company or any assets or securities of the Company; 

     (g) the Purchaser shall have reached an agreement or understanding with 
    the Company providing for termination of the Offer, or the Purchaser or 
    any of its affiliates shall have entered into a definitive agreement or 
    announced an agreement in principle with the Company providing for a 
    merger or other business combination with the Company or the purchase of 
    stock or assets of the Company; 

     (h) the Purchaser shall become aware (i) that any material contractual 
    right of the Company or any of its subsidiaries or affiliates shall be 
    impaired or otherwise adversely affected or that any material amount of 
    indebtedness of the Company or any of its subsidiaries, joint ventures or 

                                       18
<PAGE>

    partnerships shall become accelerated or otherwise become due before its 
    stated due date, in either case with or without notice or the lapse of 
    time or both, as a result of the transactions contemplated by the Offer or 
    (ii) of any covenant, term or condition in any of the Company's or any of 
    its subsidiaries', joint ventures' or partnerships' instruments or 
    agreements that is or may be materially adverse to the value of the Shares 
    in the hands of the Purchaser (including, but not limited to, any event of 
    default that may ensue as a result of the consummation of the Offer or the 
    acquisition of control of the Company); or 

     (i) CalEnergy or the Purchaser shall not have obtained any waiver, 
    consent, extension, approval, action or non-action from any governmental 
    authority or agency which is necessary to consummate the Offer, including 
    without limitation, the expiration or termination of the waiting period 
    under the HSR Act; 

which, in the sole judgment of the Purchaser in any such case, and regardless 
of the circumstances (including any action or inaction by the Purchaser or 
any of its affiliates) giving rise to any such condition, makes it 
inadvisable to proceed with the Offer and/or with such acceptance for payment 
or payment. 

   The foregoing conditions are for the sole benefit of the Purchaser and may 
be asserted by the Purchaser regardless of the circumstances giving rise to 
such condition or may be waived by the Purchaser in whole or in part at any 
time and from time to time in the sole discretion of the Purchaser. Any 
determination by the Purchaser concerning any event described in this Section 
12 shall be final and binding upon all parties. 

   13. SOURCE AND AMOUNT OF FUNDS. The Purchaser estimates that the total 
amount of funds required to purchase the Shares in the Offer will be 
approximately $160 million. The Purchaser will obtain such funds through a 
capital contribution by CalEnergy from available cash on hand. 

   14. DIVIDENDS AND DISTRIBUTIONS. If, on or after the date of this Offer to 
Purchase, the Company should split, combine or otherwise change the Shares or 
its capitalization, or shall disclose that it has taken any such action, 
then, subject to the provisions of Section 12, the Purchaser may, in its sole 
judgment, make such adjustments as it deems appropriate to reflect such 
split, combination or other change in the purchase price and the other terms 
of the Offer (including, without limitation, the number and type of 
securities offered to be purchased, the amounts payable therefor and the fees 
payable hereunder). 

   If, on or after the date of this Offer to Purchase, the Company should 
declare or pay any cash or stock dividend or other distribution on or issue 
any rights with respect to the Shares, payable or distributable to 
shareholders of record on a date before the transfer to the name of the 
Purchaser or its nominee or transferee on the Company's stock transfer 
records of the Shares accepted for payment pursuant to the Offer, then, 
subject to the provisions of Section 12, (i) the purchase price per Share 
payable by the Purchaser pursuant to the Offer will be reduced by the amount 
of any such cash dividend (other than the regular quarterly cash dividend of 
$.35 per Share payable on August 15, 1997 to holders of record as of the 
close of business on July 25, 1997) or cash distribution and (ii) the whole 
of any such non-cash dividend, distribution or right will be received and 
held by the tendering shareholder for the account of the Purchaser and shall 
be required to be promptly remitted and transferred by each tendering 
shareholder to the Depositary for the account of the Purchaser, accompanied 
by appropriate documentation of transfer. Pending such remittance, the 
Purchaser will be entitled to all rights and privileges as owner of any such 
non-cash dividend, distribution or right and may withhold the entire purchase 
price or deduct from the purchase price the amount or value thereof, as 
determined by the Purchaser in its sole discretion. 

   15. CERTAIN LEGAL MATTERS. Except as otherwise disclosed herein, on the 
basis of an examination of publicly available filings with respect to the 
Company, the Purchaser is not aware of any licenses or other regulatory 
permits which appear to be material to the business of the Company and which 
might be adversely affected by the acquisition of Shares by the Purchaser 
pursuant to the Offer or of any approval or other action by any governmental, 
administrative or regulatory agency or authority which would be required for 
the acquisition or ownership of Shares by the Purchaser as contemplated 
herein. Should any such approval or other action be required, it is currently 
contemplated that such approval or action would 

                                       19
<PAGE>

be sought. The Purchaser is unable to predict whether it may determine that 
it is required to delay the acceptance for payment of Shares pursuant to the 
Offer pending such approval or other action. There cannot be any assurance 
that any such approval or other action, if needed, would be obtained without 
substantial conditions or that adverse consequences might not result to the 
Company's business or that certain parts of the Company's business might not 
have to be disposed of if such approvals were not obtained or such other 
actions were not taken, any of which could cause the Purchaser to elect to 
terminate the Offer pursuant to Section 12. 

   State Takeover Laws. A number of states (including New York) have adopted 
laws and regulations containing restrictions that apply to offers to acquire 
securities of corporations which are incorporated and/or have assets, 
shareholders and/or conduct business therein. In 1982, the United States 
Supreme Court in Edgar v. Mite Corp. invalidated on constitutional grounds 
the Illinois Business Takeovers Statute which, as a matter of state 
securities law, imposed procedural requirements of additional filings, a 
waiting period and a fairness hearing on tender offers, on the ground that 
the requirements imposed by the state takeover statute which made takeovers 
of corporations meeting certain requirements more difficult, conflicted with 
federal law. The reasoning in that decision is likely to apply to other state 
takeover statutes that purport to impose similar requirements on the Offer. 

   In 1987, the United States Supreme Court in CTS Corp. v. Dynamics Corp. of 
America held that the State of Indiana could, as a matter of corporate law 
and, in particular, those aspects of corporate law concerning corporate 
governance, constitutionally disqualify a potential acquiror from voting on 
the affairs of a target corporation, without the prior approval of a majority 
vote of those shareholders of the corporation who had no interest in the 
acquisition and who were neither officers nor directors and employees of the 
corporation, provided that such laws were applicable only to Indiana 
corporations. Subsequently, certain United States District Courts have ruled 
that state takeover statutes, even of the type upheld in CTS Corp., are 
unconstitutional insofar as they apply to corporations incorporated outside 
that state. In TLX Acquisition Corp. v. Telex Corp., a United States District 
Court in Oklahoma ruled that Oklahoma takeover statutes were unconstitutional 
insofar as they applied to corporations incorporated outside Oklahoma in that 
they would subject such corporations to inconsistent regulations. Similarly 
in Tyson Foods, Inc. v. McReynolds, a United States District Court in 
Tennessee ruled that four Tennessee takeover statutes were unconstitutional 
as they applied to corporations incorporated outside Tennessee. This decision 
was affirmed by the United States Court of Appeals for the Sixth Circuit. The 
reasoning of these cases may indicate that application of the takeover 
statutes of states other than New York to the Offer could be 
unconstitutional. 

   Various states, including New York, also have enacted business combination 
statutes that regulate the circumstances under which a corporation may merge 
or enter into other business combinations with an acquiror of certain 
percentages of their outstanding stock. In Amanda Acquisition Corp. v. 
Universal Foods Corp., the United States Court of Appeals for the Seventh 
Circuit held that the state of Wisconsin could, as a matter of state law, 
prohibit for a period of three years, a Wisconsin corporation from entering 
into certain business combinations, including a merger, with a holder of 10% 
or more of the outstanding stock of the corporation, unless the corporation's 
Board of Directors had approved the transaction prior to the time the 
acquiror purchased its 10% interest in the corporation. Certiorari to the 
United States Supreme Court was denied. 

   The Company and certain of its subsidiaries conduct business in a number 
of states throughout the United States, some of which have enacted takeover 
statutes. The Purchaser does not know whether any or all of these statutes 
will by their terms apply to the Offer. To the extent that state takeover 
statutes and regulations purport to apply to the Offer, and contain 
provisions that impose requirements that conflict with the United States 
Constitution or conflict with the federal securities laws applicable to the 
Offer, the Purchaser believes that such statutes and regulations are 
unconstitutional and/or preempted by federal law. Should the Company, any 
government agency or official or any other person seek to apply any such 
statute to the Offer, the Purchaser will take such action as then appears 
desirable and may contest the validity of such statutes and the application 
of such statutes to the Offer in appropriate judicial or administrative 
proceedings. If it is asserted that one or more state takeover laws is 
applicable to the Offer and an appropriate court does not determine that it 
is inapplicable or invalid as applied to the Offer, the 

                                       20
<PAGE>

Purchaser may be required to file certain information with, or receive 
approvals from, the relevant state authorities, and, if enjoined, the 
Purchaser may be unable to purchase Shares tendered pursuant to the Offer or 
may be delayed in consummating the Offer. In the circumstances described 
above, the Purchaser may not be obliged to purchase any Shares tendered. See 
Section 12. Without conceding the constitutionality or applicability of 
Article 16 of the New York Business Corporation Law or otherwise prejudicing 
its rights to challenge the constitutionality or applicability of such 
Article, CalEnergy and the Purchaser have filed a registration statement 
pursuant to such Article with the New York Attorney General and have included 
in Schedule III to this Offer to Purchase certain additional information 
concerning CalEnergy and the Purchaser in compliance with such Article. 

   Antitrust. Under the HSR Act, certain acquisition transactions may not be 
consummated unless certain information has been furnished to the FTC and the 
Antitrust Division and certain waiting period requirements have been 
satisfied. The Offer is subject to these requirements. See Section 2. 

   Under the provisions of the HSR Act applicable to the purchase of Shares 
pursuant to the Offer, purchases cannot be made until the expiration of a 
15-day waiting period after July 17, 1997, the date on which certain required 
information and documentary material was furnished by the Purchaser to the 
FTC and the Antitrust Division with respect to the Offer, unless both the FTC 
and the Antitrust Division terminate the waiting period with respect thereto. 
If, within such 15-day waiting period, either the FTC or the Antitrust 
Division requests additional information or documentary material relevant to 
the Offer, the waiting period will be extended for an additional period of 
ten days following the date of substantial compliance with such requests. 
Accordingly, the required waiting period will expire at 11:59 P.M., New York 
City time, on August 1, 1997, unless a request for additional information or 
documentary material is received before then. Thereafter, the waiting period 
could be extended only by court order or with the Purchaser's consent. The 
Purchaser will not accept for payment Shares tendered pursuant to the Offer 
unless and until the waiting period requirement imposed by the HSR Act has 
been satisfied. 

   The Antitrust Division, the FTC and state authorities frequently 
scrutinize the legality under the antitrust laws of transactions such as the 
acquisition of Shares pursuant to the Offer. At any time before or after the 
consummation of any of such transactions, the Antitrust Division, the FTC or 
state authorities could take such action under the antitrust laws as it deems 
necessary or desirable in the public interest, including seeking to enjoin 
the purchase of Shares pursuant to the Offer or otherwise, or seeking the 
divestiture of Shares acquired by the Purchaser or the divestiture of 
substantial assets of the Company. Private parties may also seek to take 
action under the antitrust laws. The Purchaser believes that the acquisition 
of Shares pursuant to the Offer will not violate the antitrust laws. However, 
there can not be any assurance that a challenge to the Offer on antitrust 
grounds will not be made, or if such a challenge is made, what the result 
will be. See Section 12 for certain conditions of the Offer, including 
conditions with respect to injunctions and certain governmental actions. 

   Subsequent Regulatory Approvals in Connection with Future Share 
Acquisitions or Merger. 

   Following completion of the Offer, the Purchaser intends to seek 
regulatory approvals permitting the acquisition and ownership of 100% of the 
Common Stock and, after receiving such approvals, to acquire all of the 
outstanding Shares it does not then own. See Section 11. The regulatory 
approvals that would be needed in order to permit the Purchaser to acquire 
all of the outstanding Shares are described below. 

   State Regulatory Approvals. Approval of the Public Service Commission of 
New York ("PSC") will be required for the acquisition of the remaining 
outstanding shares of the Common Stock. The PSC considers whether the 
acquisition would be in the public interest, taking into account such factors 
as the impact of the merger on consumers, on rates, and on quality of 
service. The PSC also would have to approve any issuance of securities of the 
Company made in connection with the Purchaser's acquisition. The PSC approval 
process typically takes from six to twelve months, depending upon the issues 
involved. The Purchaser does not believe approval from any other state 
commissions are also required. However, if required, the Purchaser believes 
any such approvals should be obtainable in the same time frame as the PSC 
approval. 

   Federal Power Act. The Federal Energy Regulatory Commission ("FERC") has 
determined that its approval is required under Section 203 of the Federal 
Power Act (the "FPA") before any person can 

                                       21
<PAGE>

acquire a controlling interest in a public utility. Therefore FERC's approval 
will be required before the Purchaser can acquire the remaining outstanding 
shares of the Common Stock of the Company. Under Section 203 of the FPA, FERC 
must approve a proposed disposition of facilities if it finds that the 
disposition will be consistent with the public interest. The FERC approval 
process is expected to take anywhere from six to twelve months, depending 
upon the complexity of the issues involved. 

   Atomic Energy Act. The Company has an 18% ownership interest in the Nine 
Mile Nuclear Generating Unit # 2 ("Nine Mile Unit # 2"). The remaining 
ownership interests are held by Niagara Mohawk Power Corp., which is the 
operator, and by Long Island Lighting Company, Rochester Gas & Electric Corp. 
and Central Hudson Gas & Electric Corp. As an owner, the Company holds a 
possession-only license issued by the Nuclear Regulatory Commission ("NRC") 
under the Atomic Energy Act for Nine Mile Unit # 2. The purchase of the 
remaining outstanding shares of the Common Stock of the Company will be 
considered an indirect change of control of the license, and will require the 
prior approval of the NRC. The Purchaser believes such approval should be 
obtainable in the same time frame as the FERC approval. 

   Others. Based on an examination of publicly available information with 
respect to the Company, the Purchaser is not aware of any other regulatory 
approval that would be required prior to the acquisition of the remaining 
outstanding shares of the Common Stock. However, there may be a requirement 
to obtain approvals of the transfer of licenses, franchises or other permits; 
such approvals should be granted in the ordinary course of business. The 
Purchaser presently intends to take such actions with respect to any 
additional approvals that may be needed as will enable it to acquire the 
remaining outstanding shares of the Common Stock subsequent to the completion 
of the Offer. In addition, certain partial dispositions may be required in 
order to maintain the qualifying facility status (under the Public Utility 
Regulatory Policies Act of 1978) of certain of CalEnergy's independent 
generating facilities following its acquisition of more than 9.9% of the 
Company. 

   16. FEES AND EXPENSES. Lehman Brothers and Credit Suisse First Boston are

consummation by CalEnergy of an acquisition of a majority of the Common Stock

the Purchaser for customary mailing and handling expenses incurred by them in

   17. MISCELLANEOUS. The Offer is being made to all holders of Shares. The 
Purchaser is not aware of any state where the making of the Offer is

3. POTENTIAL IMPACT ON THE NEW YORK RESIDENTS OF CALENERGY'S PLANS AND 
PROPOSALS 

   CalEnergy believes that its proposed business combination would yield many 
benefits for the Company's customers and employees and the State of New York. 
CalEnergy welcomes the various initiatives of the Governor's office, the New 
York legislature and the New York Public Service Commission to introduce full 
competition to New York's energy market. CalEnergy fully expects that it will 
be able to work closely with the New York Public Service Commission to 
implement rate reductions for all the Company's customers, while providing 
them with the same safe and reliable energy service to which they are 
accustomed. Lower rates would give the Company an advantage in meeting the 
competitive challenges of the deregulating energy market while contributing 
to New York's economic vitality and ability to attract and retain jobs. 
CalEnergy intends to reincorporate CalEnergy in New York and maintain the 
Company as a distinct operating unit with its existing corporate headquarters 
and grow the Company's business by participating aggressively in the 
increasingly competitive New York electric market. CalEnergy is a growth 
company that has increased its number of employees tenfold in the last five 
years. 

4. PENSION PLANS, PROFIT-SHARING PLANS AND OTHER MATTERS 

   CalEnergy maintains a full range of employee health and benefit and 
insurance plans and provides a matching 401(k) retirement savings plan for 
all employees, as well as employee bonus plans, employee stock purchase and 
employee stock option plans. 

   (i) CalEnergy Company, Inc. 401(k) Savings Plan. This plan permits 
employees to defer up to 15 percent of their compensation (as defined in the 
plan) annually on a pre-tax basis, subject to legally imposed limitations. 
CalEnergy also automatically makes matching contributions to the plan, in the 
amount determined by CalEnergy, to be allocated based on the amounts of the 
employees' contributions. The employees are always vested in 100 percent of 
their contributions and CalEnergy's matching contributions. The investment 
options under the plan consist of mutual funds and a CalEnergy stock fund. 

                                      S-8
<PAGE>

    (ii) CalEnergy Company, Inc. Employee Stock Option Plan. CalEnergy 
maintains the Employee Stock Option Plan, which provides for grants of 
incentive and nonqualified stock options to directors, employees, consultants 
and independent contractors of CalEnergy. The exercise price of an incentive 
stock option granted under the plan generally must be not less than the fair 
market value of CalEnergy Common Stock at the date of grant; the exercise 
price of a nonqualified option is determined by the committee administering 
the plan and cannot be less than 85% of the fair market value at the time of 
grant. CalEnergy has reserved 3,739,165 shares of CalEnergy Common Stock for 
issuance under the Plan. 

   (iii) CalEnergy Company, Inc. Employee Stock Purchase Plan. This plan 
permits participating employees to purchase CalEnergy Common Stock at a price 
below its market value and to pay for the purchases through payroll 
deductions. The purchase price is set at a discount of 15% from the lower of 
the market value of CalEnergy Common Stock on the last trading day before a 
six-month participation period starts or on the last trading day in the 
participation period. The aggregate fair market value of the shares of 
CalEnergy Common Stock that may be purchased under the plan by any 
participant in any calendar year may not exceed $25,000. 

   (iv) Insurance. CalEnergy provides term life and other accidental death 
and disability insurance coverage to its employees at no cost. 

5. PENDING LEGAL PROCEEDINGS 

   CalEnergy is not a party to any material pending legal proceedings. 

6. LABOR AND EMPLOYEE RELATIONS 

   As of March 31, 1997, CalEnergy and its subsidiaries had approximately 
4,500 employees. CalEnergy's labor and employment relations with its 
employees are excellent. There have been no violations by CalEnergy of the 
Federal National Labor Relations Act, Occupational Safety and Health Act of 
1970, Fair Labor Standards Act or Employee Retirement and Income Security 
Act, as amended, finally adjudicated or settled within five years of the 
commencement of the Offer. 

7. EDUCATIONAL OPPORTUNITIES 

   CalEnergy provides special job training programs and, in certain 
circumstances, educational assistance to eligible employees who pursue 
programs of study that are related to the employees' field of work. 

8. RELOCATION ADJUSTMENTS 

   CalEnergy reimburses job applicants, new employees and current employees 
for certain travel and relocation expenses. 

9. CHARITABLE AND CIVIC ACTIVITIES 

   Consistent with CalEnergy's commitment to responsible community 
involvement, CalEnergy supports the arts and a variety of charitable 
foundations, particularly in communities in which CalEnergy operates 
facilities or has offices. Additionally, CalEnergy is active in community 
safety programs, environmental activities and educational organizations by 
making contributions and matching gifts to certain accredited institutions of 
higher education, college associations and other educational organizations.

                    NOTE: SIGNATURES MUST BE PROVIDED BELOW.

              PLEASE READ CAREFULLY THE ACCOMPANYING INSTRUCTIONS.

Ladies and Gentlemen: 

   The undersigned hereby tenders to CE Electric (NY), Inc., a New York 
corporation (the "Purchaser") and a wholly owned subsidiary of CalEnergy 
Company, Inc., a Delaware corporation ("CalEnergy"), the above described 
shares of common stock, par value $6.66 2/3 per share (the "Shares"), of New 
York State Electric & Gas Corporation, a New York corporation (the 
"Company"), pursuant to the Purchaser's offer to purchase 6,540,670 Shares, 
at $24.50 per Share, net to the seller in cash, without interest thereon, 
upon the terms and subject to the conditions set forth in the Offer to 
Purchase dated July 18, 1997 (the "Offer to Purchase") receipt of which is 
hereby acknowledged, and in this Letter of Transmittal (which, together with 
the Offer to Purchase, constitutes the "Offer"). The undersigned understands 
that the Purchaser reserves the right to transfer or assign, in whole and 
from time to time in part, to one or more direct or indirect subsidiaries of 
CalEnergy, the right to purchase Shares tendered pursuant to the Offer, but 
any such transfer or assignment will not relieve the Purchaser of its 
obligations under the Offer or prejudice the rights of tendering shareholders 
to receive payment for Shares validly tendered and accepted for payment 
pursuant to the Offer. 

   Subject to, and effective upon, acceptance for payment of the Shares 
tendered herewith in accordance with the terms and subject to the conditions 
of the Offer, the undersigned hereby sells, assigns and transfers to, or upon 
the order of, the Purchaser all right, title and interest in and to all the 
Shares that are being tendered hereby and that are being accepted for 
purchase pursuant to the Offer (and any and all dividends, distributions, 
stock splits, other Shares, rights or other securities issued or issuable in 
respect of the Shares on or after July 18, 1997, other than the regular 
quarterly cash dividend of $.35 per Share payable on August 15, 1997 to 
holders of record as of the close of business on July 25, 1997) which are 
payable or distributable to shareholders of record on a date prior to the 
transfer into the name of the Purchaser or its nominees or transferees on the 
Company's stock transfer records of the Shares purchased pursuant to the 
Offer (a "Distribution"), and irrevocably constitutes and appoints the 
Depositary the true and lawful attorney-in-fact and proxy of the undersigned 
with respect to such Shares (and any dividends, distributions, other Shares, 
rights or securities, including Distributions) with full power of 
substitution and resubstitution (such power of attorney being deemed to be an 
irrevocable power coupled with an interest), to (a) deliver certificates for 
such Shares (and any such dividends, distributions, other Shares, rights or 
securities, including Distributions), or transfer ownership of such Shares on 
the account books maintained by a Book-Entry Transfer Facility, together in 
either such case with all accompanying evidences of transfer and 
authenticity, to or upon the order of the Purchaser upon receipt by the 
Depositary, as the undersigned's agent, of the purchase price (adjusted, if 
appropriate, as provided in the Offer to Purchase), (b) present such Shares 
(and any dividends, distributions, other Shares, rights or securities, 
including Distributions) for transfer on the books of the Company and (c) 
receive all benefits and otherwise exercise all rights of beneficial 
ownership of such Shares (and any such dividends, distributions, other 
Shares, rights or securities, including Distributions), all in accordance 
with the terms of the Offer. 

   The undersigned hereby irrevocably appoints David L. Sokol and Steven A. 
McArthur and each of them, or any other designees of the Purchaser, the 
attorneys-in-fact and proxies of the undersigned, each with full power of 
substitution and resubstitution (such power of attorney being deemed to be an 
irrevocable power coupled with an interest), to vote or act by 

                                       3
<PAGE>

written consent in such manner as each such attorney and proxy or his 
substitute shall in his sole discretion deem proper, and otherwise to act 
with respect to all the Shares tendered hereby that have been accepted for 
payment by the Purchaser prior to the time of such vote or action (and any 
and all non-cash dividends, distributions, other Shares, rights or securities 
issued or issuable in respect thereof on or after July 18, 1997), at any 
meeting of shareholders (whether regular or special and whether or not an 
adjourned or postponed meeting) of the Company, or consent in lieu of any 
such meeting, or otherwise. All such powers of attorney and proxies are 
irrevocable and coupled with an interest in the tendered Shares and are 
granted in consideration of, and are effective when, and only to the extent 
that, the Purchaser accepts such Shares for payment. Such acceptance for 
payment shall revoke any other proxies granted by the undersigned at any time 
with respect to such Shares (and any such non-cash dividends, distributions, 
other Shares, rights or other securities, including Distributions) and no 
subsequent proxies or written consents will be given (and if given will be 
deemed not to be effective) with respect thereto by the undersigned. The 
Purchaser reserves the right to require that in order for Shares to be 
validly tendered, immediately upon the Purchaser's acceptance of such Shares 
for purchase, the Purchaser is able to exercise full voting and other rights 
of a record and beneficial holder, including the right to act by written 
consent, with respect to such Shares (and any Distributions). 

   The undersigned hereby represents and warrants that the undersigned has 
full power and authority to tender, sell, assign and transfer the Shares 
tendered hereby (and any and all dividends, distributions, other Shares, 
rights or other securities issued or issuable in respect thereof, including 
Distributions, on or after July 18, 1997, other than the regular quarterly 
cash dividend of $.35 per Share payable on August 15, 1997 to holders of 
record as of the close of business on July 25, 1997) ) and that, when the 
same are accepted for payment by the Purchaser, the Purchaser will acquire 
good and unencumbered title thereto, free and clear of all pledges, liens, 
restrictions, charges, proxies and encumbrances and the same will not be 
subject to any adverse claim. 

   Upon request, the undersigned will execute and deliver any additional 
documents deemed by the Depositary or the Purchaser to be necessary or 
desirable to complete the sale, assignment and transfer of the Shares 
tendered hereby (and any and all dividends, distributions, such other Shares, 
rights or other securities, including Distributions, other than the regular 
quarterly cash dividend of $.35 per Share payable on August 15, 1997 to 
holders of record as of the close of business on July 25, 1997) ). In 
addition, the undersigned shall promptly remit and transfer to the Depositary 
for the account of the Purchaser any and all other Shares or other 
securities, including Distributions, issued to the undersigned on or after 
July 18, 1997 in respect of Shares tendered hereby, accompanied by 
appropriate documentation of transfer, and, pending such remittance or 
appropriate assurance thereof, the Purchaser shall be entitled to all rights 
and privileges as owner of any such other Shares or other securities and may 
withhold the entire consideration or deduct from the consideration the amount 
or value thereof, as determined by the Purchaser in its sole discretion. 

   All authority herein conferred or agreed to be conferred in this Letter of 
Transmittal shall not be affected by, and shall survive, the death or 
incapacity of the undersigned and any obligation of the undersigned hereunder 
shall be binding upon the successors, assigns, heirs, executors, 
administrators and legal and personal representatives of the undersigned. 
Except as sted in the Offer to Purchase and this Letter of Transmittal, this 
tender is irrevocable. 

   The undersigned understands that tenders of Shares pursuant to any one of 
the procedures described in the Offer to Purchase and in the instructions 
hereto will constitute a binding agreement between the undersigned and the 
Purchaser upon the terms and subject to the conditions of the Offer. 

   Unless otherwise indicated herein under "Special Payment Instructions," 
please issue the check for the purchase price and/or return any certificates 
for Shares not tendered or accepted for payment in the name(s) of the 
registered holder(s) appearing under "Description of Shares Tendered." 
Similarly, unless otherwise indicated under "Special Delivery Instructions," 
please mail the check for the purchase price and/or return any certificates 
for Shares not tendered or accepted for payment (and accompanying documents, 
as appropriate) to the registered holder(s) appearing under "Description of 
Shares Tendered" at the address shown below the undersigned's signature. If 
both the Special Delivery Instructions and the Special Payment Instructions 
are completed, please issue the check for the purchase price, and/or return 
any certificates for Shares not tendered or accepted for payment in the name 
of, and deliver said certificates and check and return such certificates to, 
the person or persons so indicated. Shareholders delivering Shares by 
book-entry transfer may request that any Shares not accepted for payment be 
returned by crediting such account maintained at a Book-Entry Transfer 
Facility as such shareholder may designate by making an appropriate entry 
under "Special Payment Instructions." The undersigned recognizes that the 
Purchaser has no obligation pursuant to the Special Payment Instructions to 
transfer any Shares from the name of the registered holder thereof if the 
Purchaser does not accept for payment any of the Shares so tendered.

             FORMING PART OF THE TERMS AND CONDITIONS OF THE OFFER

   1. GUARANTEE OF SIGNATURES. No signature guarantee on this Letter of 
Transmittal is required (i) if this Letter of Transmittal is signed by the 
registered holder of the Shares (which term, for the purposes of this 
document, shall include any participant in a Book-Entry Transfer Facility 
whose name appears on a security position listing as the owner of Shares) 
tendered herewith, unless such holder has completed either the box entitled 
"Special Payment Instructions" or the box entitled "Special Delivery 
Instructions" on the reverse hereof or (ii) if such Shares are to be tendered 
for the account of a bank, broker, dealer, credit union, savings association 
or other entity which is a member in good standing of the Securities Transfer 
Agent's Medallion Program (collectively, "Eligible Institutions"). In all 
other cases, all signatures on the Letter of Transmittal must be guaranteed 
by an Eligible Institution. If the Certificates are registered in the name of 
a person other than the signer of this Letter of Transmittal, or payment of 
the purchase price is to be made or certificates for unpurchased Shares are 
to be issued or returned to a person other than the registered owner, then 
the tendered Certificates must be endorsed or accompanied by duly executed 
stock powers, in either case signed exactly as the name or names of the 
registered owner or owners appear on the Certificates, with the signature(s) 
on the Certificates or stock powers guaranteed by an Eligible Institution. 
See Instruction 5. 

   2. DELIVERY OF LETTER OF TRANSMITTAL AND CERTIFICATES. This Letter of 
Transmittal is to be completed by shareholders either if certificates are to 
be forwarded herewith or if tenders of Shares are to be made pursuant to the 
procedures for delivery by book-entry transfer set forth in the Offer to 
Purchase. Certificates for all physically tendered Shares, or timely 
confirmation of any book-entry transfer into the Depositary's accounts at DTC 
or PHDTC or Shares tendered by book-entry transfer, as the case may be, as 
well as a properly completed and duly executed Letter of Transmittal (or 
facsimile thereof) with any required signature guarantees, or an Agent's 
Message in the case of a book-entry delivery, and any other documents 
required by this Letter of Transmittal, must be received by the Depositary at 
one of its addresses set forth herein on or prior to the Expiration Date (as 
defined in the Offer to Purchase), or who cannot deliver their certificates 
and all other required documents to the Depositary on or prior to the 
Expiration Date or who cannot complete the procedures for delivery by 
book-entry transfer on a timely basis may tender their Shares by properly 
completing and duly executing the Notice of Guaranteed Delivery pursuant to 
the guaranteed delivery procedure set forth in the Offer to Purchase. 
Pursuant to such procedure: (i) such tender must be made by or through an 
Eligible Institution, (ii) a properly completed and duly executed Notice of 
Guaranteed Delivery, substantially in the form provided by the Purchaser, 
must be received by the Depositary on or before the Expiration Date and (iii) 
the certificates for all tendered Shares or confirmation of any book-entry 
transfer into the Depositary's account at DTC or PHDTC of Shares tendered by 
book-entry transfer, as the case may be, together with a properly completed 
and duly executed Letter of Transmittal (or facsimile thereof) with any 
required signature guarantees (or, in the case of a book-entry transfer, an 
Agent's Message (as defined in the Offer to Purchase)), and all other 
documents required by this Letter of Transmittal, must be received by the 
Depositary within three New York Stock Exchange trading days after the date 
of execution of such Notice of Guaranteed Delivery to the Depositary. If 
Certificates are forwarded separately to the Depositary, a properly completed 
and duly executed Letter of Transmittal (or a facsimile thereof) must 
accompany each such delivery. 

   THE METHOD OF DELIVERY OF SHARES, THIS LETTER OF TRANSMITTAL AND ANY OTHER 
REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH A BOOK-ENTRY TRANSFER 
FACILITY, IS AT THE OPTION AND RISK OF THE TENDERING SHAREHOLDER AND, EXCEPT 
AS OTHERWISE PROVIDED IN THIS INSTRUCTION 2, THE DELIVERY WILL BE DEEMED MADE 
ONLY WHEN ACTUALLY RECEIVED BY THE DEPOSITARY. IF DELIVERY IS BY MAIL, 
REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS 
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY 
DELIVERY. 

   No alternative, conditional or contingent tenders will be accepted and no 
fractional Shares will be purchased. All tendering shareholders, by execution 
of this Letter of Transmittal (or facsimile thereof), waive any right to 
receive any notice of the acceptance of their Shares for payment. 

   3. INADEQUATE SPACE. If the space provided herein is inadequate, the 
certificate numbers and/or the number of Shares should be listed on a 
separate signed schedule attached hereto. 

   4. PARTIAL TENDERS (NOT APPLICABLE TO SHAREHOLDERS WHO TENDER BY 
BOOK-ENTRY TRANSFER). If fewer than all the Shares evidenced by any 
certificate submitted are to be tendered, fill in the number of Shares which 
are to be tendered in the box 

                                       7
<PAGE>

entitled "Number of Shares Tendered". In such case, new certificate(s) for 
the remainder of the Shares that were evidenced by old certificate(s) will be 
sent to the registered holder, unless otherwise provided in the boxes 
entitled "Special Payment Instructions" or "Special Delivery Instructions" on 
this Letter of Transmittal, as soon as practicable after the Expiration Date. 
All Shares represented by certificates delivered to the Depositary will be 
deemed to have been tendered unless otherwise indicated. 

   5. SIGNATURES ON LETTER OF TRANSMITTAL, STOCK POWERS AND ENDORSEMENTS. (a) 
If this Letter of Transmittal is signed by the registered holder(s) of the 
Shares tendered hereby, the signature(s) must correspond exactly with the 
name(s) as written on the face of the certificate(s) without alteration, 
enlargement or any change whatsoever. 

   (b) If any of the Shares tendered hereby are owned of record by two or 
more joint owners, all such owners must sign this Letter of Transmittal. 

   (c) If any tendered Shares are registered in different names on several 
certificates, it will be necessary to complete, sign and submit as many 
separate Letters of Transmittal as there are different registrations of 
certificates. 

   (d) If this Letter of Transmittal or any certificates or stock powers are 
signed by a trustee, executor, administrator, guardian, attorney-in-fact, 
officer of a corporation or other person acting in a fiduciary or 
representative capacity, such person should so indicate when signing, and 
proper evidence satisfactory to the Purchaser of such person's authority so 
to act must be submitted. 

   (e) When this Letter of Transmittal is signed by the registered holder(s) 
of the Shares listed and transmitted hereby, no endorsements of certificates 
or separate stock powers are required unless payment is to be made to, or 
certificates for Shares not tendered or purchased are to be issued in the 
name of, a person other than the registered holder(s). Signatures on such 
certificates or stock powers must be guaranteed by an Eligible Institution 
(unless signed by an Eligible Institution). 

   (f) If this Letter of Transmittal is signed by a person other than the 
registered holder(s) of the Shares listed, 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 certificates. 
Signatures on such certificates or stock powers must be guaranteed by an 
Eligible Institution (unless signed by an Eligible Institution). 

   6. STOCK TRANSFER TAXES. Except as set forth in this Instruction 6, the 
Purchaser will pay or cause to be paid any stock transfer taxes with respect 
to the transfer and sale of purchased Shares to it or its order pursuant to 
the Offer. If payment of the purchase price is to be made to, or if 
certificates for Shares not tendered or purchased are to be registered in the 
name of, any person other than the registered holder, or if tendered 
certificates are registered in the name of any person other than the 
person(s) signing this Letter of Transmittal, the amount of any stock 
transfer taxes (whether imposed on the registered holder or such other 
person) 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. 

   Except as provided in this Instruction 6, it will not be necessary for 
transfer tax stamps to be affixed to the certificates listed in this Letter 
of Transmittal. 

   7. SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS. If a check is to be issued 
in the name of, and/or certificates for unpurchased Shares are to be returned 
to, a person other than the signer of this Letter of Transmittal or if a 
check is to be sent and/or certificates for unpurchased Shares are to be 
returned to someone other than the signer of this Letter of Transmittal or to 
an address other than that shown above, the appropriate boxes on this Letter 
of Transmittal should be completed. Shareholders tendering Shares by 
book-entry transfer may request that the Shares not purchased be credited to 
such account maintained at a Book-Entry Transfer Facility as such shareholder 
may designate hereon. If no such instructions are given, such Shares not 
purchased will be returned by crediting the account at a Book-Entry Transfer 
Facility designated above. See Instruction 1. 

   8. REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES. Requests for assistance 
may be directed to, or additional copies of the Offer to Purchase and this 
Letter of Transmittal may be obtained from, either the Information Agent or 
the Dealer Managers at their respective addresses set forth below or from 
your broker, dealer, commercial bank or trust company. 

   9. IRREGULARITIES. All questions as to the validity (including time of 
receipt) and acceptance for payment of any tender of Shares will be 
determined by the Purchaser, in its sole discretion, whose determination 
shall be final and binding. The Purchaser reserves the absolute right to 
reject any and all tenders determined by it not to be in the appropriate form 
or the acceptance for purchase of which may, in the opinion of its counsel, 
be unlawful. As set forth in the Offer to Purchase, the 

                                       8
<PAGE>

Purchaser also reserves the absolute right to waive any of the conditions of 
the Offer or any defect or irregularity in the tender of any Shares of any 
particular shareholder whether or not similar defects or irregularities are 
waived in the case of other shareholders. The Purchaser's interpretations of 
the terms and conditions of the Offer (including these instructions) will be 
final and binding. Unless waived, any defects or irregularities must be cured 
within such time as the Purchaser shall determine. None of the Purchaser, the 
Dealer Managers, the Depositary, the Information Agent or any other person 
will be under any duty to give notice of any defects or irregularities in 
tenders or shall incur any liability for failure to give any such 
notification. Tenders shall not be deemed to have been made until all defects 
and irregularities have been cured or waived. 

   10. 31% BACKUP WITHHOLDING; SUBSTITUTE FORM W-9. Under federal income tax 
laws, a shareholder whose tendered Shares are accepted for payment is 
required to provide the Depositary with such shareholder's correct taxpayer 
identification number ("TIN") on Substitute Form W-9 below and certify under 
penalties of perjury that such number is correct and that such shareholder is 
not subject to backup withholding. If the Depositary is not provided with the 
correct TIN and certifications are not provided, the Internal Revenue Service 
may subject the shareholder or other payee to a $50 penalty. In addition, 
payments that are made to such shareholder or other payee with respect to 
Shares purchased pursuant to the Offer may be subject to 31% backup 
withholding. 

   Certain shareholders (including, among others, all corporations and 
certain foreign individuals) are not subject to these backup withholding and 
reporting requirements. In order for a foreign individual to qualify as an 
exempt recipient, the shareholder must submit a Form W-8, signed under 
penalties of perjury, attesting to that individual'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 
more instructions. 

   If backup withholding applies, the Depositary is required to withhold 31% 
of any such payments made to the shareholder or other payee. Backup 
withholding is not an additional tax. Rather, the tax liability of persons 
subject to backup withholding will be reduced by the amount of tax withheld. 
If withholding results in an overpayment of taxes, a refund may be obtained 
from the Internal Revenue Service. 

   The box in Part 3 of the Substitute Form W-9 may be checked if the 
tendering shareholder has not been issued a TIN and has applied for a TIN or 
intends to apply for a TIN in the near future. If the box in Part 3 is 
checked, the shareholder or other payee must also complete the Certificate of 
Awaiting Taxpayer Identification Number below in order to avoid backup 
withholding. Notwithstanding that the box in Part 3 is checked and the 
Certificate of Awaiting Taxpayer Identification Number is completed, the 
Depositary will withhold 31% of all payments made prior to the time a 
properly certified TIN is provided to the Depositary. 

   The shareholder is required to give the Depositary the TIN (e.g., social 
security number or employer identification number) of the record owner of the 
Shares or of the last transferee appearing on the transfers attached to, or 
endorsed on, the Shares. If the Shares are in more than one name or are not 
in the name of the actual owner, consult the enclosed "Guidelines for 
Certification of Taxpayer Identification Number on Substitute Form W-9" for 
additional guidance on which number to report. 

   11. LOST, DESTROYED OR STOLEN CERTIFICATES. If any certificate(s) 
representing Shares has been lost, destroyed or stolen, the shareholder 
should promptly notify the Information Agent. The shareholder will then be 
instructed as to the steps that must be taken in order to replace the 
certificate(s). This Letter of Transmittal and related documents cannot be 
processed until the procedures for replacing lost or destroyed certificates 
have been followed. 

IMPORTANT: THIS LETTER OF TRANSMITTAL (OR A FACSIMILE HEREOF) OR AN AGENT'S 
MESSAGE, TOGETHER WITH CERTIFICATES OR CONFIRMATION OF BOOK-ENTRY TRANSFER 
AND ALL OTHER REQUIRED DOCUMENTS, MUST BE RECEIVED BY THE DEPOSITARY, OR THE 
NOTICE OF GUARANTEED DELIVERY MUST BE RECEIVED BY THE DEPOSITARY, ON OR PRIOR 
TO THE EXPIRATION DATE.

AND SUBJECT TO THE CONDITIONS SET FORTH IN THE OFFER. 

   Please note the following: 

   1. The Purchaser is offering to purchase 6,540,670 Shares at $24.50 per 
Share, net to the seller in cash, without interest thereon, upon the terms

commissions or, except as set forth in Instruction 6 of the Letter of 
Transmittal, stock transfer taxes on the purchase of Shares pursuant to the

   5. Payment for Shares accepted for payment pursuant to the Offer will be

Section 4 of the Offer to Purchase) in connection with a book-entry transfer, 
and (iii) any other documents required by the Letter of Transmittal.

prohibited by administrative or judicial action pursuant to state statute. If 
the Purchaser becomes aware of any state where the making of the Offer is so 
prohibited, the Purchaser will make a good faith effort to comply with any 
such statute or seek to have such statute declared inapplicable to the Offer.

applicable statute, the Offer will not be made to (nor will tenders be 
accepted from or on behalf of) the holders of Shares in such states. In those 
jurisdictions where the laws require the Offer to be made by a licensed 
broker or dealer, the Offer is being made on behalf of the Purchaser by

registered brokers or dealers that are licensed under the laws of such 
jurisdiction.

Exempt payees described above nevertheless should file Form W-9 to avoid 
possible erroneous backup withholding. 
FILE THIS FORM WITH THE PAYER, FURNISH YOUR TIN, WRITE "EXEMPT" ON THE FACE 
OF THE FORM, AND RETURN IT TO THE PAYER. IF THE PAYMENTS ARE INTEREST, 
DIVIDENDS, OR PATRONAGE DIVIDENDS, ALSO SIGN AND DATE THE FORM. 

   Certain payments other than interest, dividends, and patronage dividends 
that are not subject to information reporting are also not subject to backup 
withholding. For details, see the Treasury regulations under sections 6041, 
6041A(a), 6045, 6050A. (All "section" references herein are 
to the Internal Revenue Code of 1986) 

PRIVACY ACT NOTICE--Section 6109 requires you to furnish your correct TIN to 
persons who must file information returns with the IRS to report interest, 
dividends, and certain other income paid to you, mortgage interest you paid, 
the acquisition or abandonment of secured property, or contributions you made 
to an IRA. The IRS uses the numbers for identification purposes and to help 
verify the accuracy of your tax return. Payers must generally withhold 31% of 
taxable interest, dividend, and certain other payments to a payee who does 
not furnish a TIN to a payer. Certain penalties may also apply. 

PENALTIES 

(1) PENALTY FOR FAILURE TO FURNISH TIN--If you fail to furnish your TIN to a 
payer, you are subject to a penalty of $50 for each such failure unless your 
failure is due to reasonable cause and not to willful neglect. 

(2) CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING--If you 
make a false statement with no reasonable basis which results in no 
imposition of backup withholding, you are subject to a penalty of $500. 

(3) CRIMINAL PENALTY FOR FALSIFYING INFORMATION--Willfully falsifying 
certifications or affirmations may subject you to criminal penalties 
including fines and/or imprisonment. 

FOR ADDITIONAL INFORMATION CONTACT YOUR TAX CONSULTANT OR THE IRS.

This announcement is neither an offer to purchase nor a solicitation of an
offer to sell shares. The Offer is made solely by the Offer to Purchase dated
July 18, 1997 and the related Letter of Transmittal and is not being made to
(nor will tenders be accepted from or on behalf of) holders of Shares in any
jurisdiction in which the making of the Offer or the acceptance thereof would
not be in compliance with the laws of such jurisdiction. In those jurisdictions
where securities, blue sky or other laws require the Offer to be made by a
licensed broker or dealer, the Offer shall be deemed to be made on behalf of CE
Electric (NY), Inc. by Lehman Brothers Inc., Credit Suisse First Boston
Corporation or one or more registered brokers or dealers licensed under the
laws of such jurisdiction.
Notice of Offer to Purchase for Cash
6,540,670 Shares of Common Stock
of
New York State Electric & Gas Corporation
at
$24.50 Net Per Share
by
CE Electric (NY), Inc.
a wholly owned subsidiary of CalEnergy Company, Inc. CE Electric (NY), Inc.
(the "Purchaser"), a New York corporation and a wholly owned subsidiary of
CalEnergy Company, Inc., a Delaware corporation ("CalEnergy"), is offering to
purchase 6,540,670 shares of common stock, par value $6.662_3 per share
("Shares"), of New York State Electric & Gas Corporation, a New York
corporation ("NYSEG"), at a price of $24.50 per Share, net to the seller in
cash, without interest thereon, upon the terms and subject to the conditions
set forth in the Offer to Purchase dated July 18, 1997 (the "Offer to
Purchase") and in the related Letter of Transmittal (which, as amended from
time to time, together constitute the "Offer"). THE OFFER, THE PRORATION PERIOD
AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00
MIDNIGHT, 
NEW YORK CITY TIME, ON THURSDAY, AUGUST 14, 1997, UNLESS THE OFFER IS EXTENDED.
The Offer is not conditioned upon the Purchaser obtaining financing. The Offer
is conditioned upon, among other things, (1) there being validly tendered and
not withdrawn prior to the expiration of the Offer that number of Shares which,
together with Shares beneficially owned by the Purchaser and its affiliates,
represents at least 9.9% of the Shares outstanding and (2) the expiration or
termination of all waiting periods imposed by the Hart-Scott-Rodino Antitrust
Improvements Act of 1976 and the regulations thereunder. The Offer is also
subject to certain other terms and conditions contained in the Offer to
Purchase. The purpose of the Offer is to enable the Purchaser to acquire that
number of Shares which, together with the Shares currently beneficially owned
by the Purchaser and its affiliates, will represent 9.9% of the total number of
Shares outstanding as the first step in its intended acquisition of 100% of the
outstanding Shares. In order for the

                                      -1-
<PAGE>

Purchaser to acquire more than 9.9% of the outstanding Shares, the Purchaser
will be required to obtain certain regulatory approvals, including approvals
from the Public Service Commission of the State of New York and the Federal
Energy Regulatory Commission.

If, as a result of repurchases of outstanding Shares by NYSEG or for any other
reason, the purchase by the Purchaser of 6,540,670 Shares pursuant to the Offer
would cause the Purchaser to own more than 9.9% of the number of Shares then
outstanding, the number of Shares to be purchased by the Purchaser pursuant to
the Offer will be reduced by an appropriate number of Shares (to be determined
by the Purchaser in its sole discretion) so that the purchase of Shares by the
Purchaser pursuant to the Offer will not cause the Purchaser to own more than
9.9% of the number of Shares then outstanding.

In addition to the Purchaser's rights to terminate the Offer pursuant to
Section 12 of the Offer to Purchase, the Purchaser expressly reserves the
right, in its sole judgment, at any time or from time to time, and regardless
of whether any of the events set forth in Section 12 of the Offer to Purchase
shall have occurred or shall have been determined by the Purchaser to have
occurred, (i) to extend the period of time during which the Offer is open and
thereby delay acceptance for payment of, and the payment for, any Shares, by
giving oral or written notice of such extension to the Depositary (as defined
in the Offer to Purchase) and (ii) to amend the Offer in any respect by giving
oral or written notice of such amendment to the Depositary. Any such extension,
amendment or termination will be followed as promptly as practicable by public
announcement thereof, such announcement in the case of an extension to be
issued not later than 9:00 A.M., New York City time, on the next business day
after the previously scheduled Expiration Date (as defined in the Offer to
Purchase).

Upon the terms and subject to the conditions of the Offer, the Purchaser will
purchase the Shares validly tendered and not withdrawn prior to the Expiration
Date in accordance with Section 4 of the Offer to Purchase, on a pro rata basis
(with adjustments to avoid purchase of fractional shares) based upon the number
of Shares validly tendered and not withdrawn prior to the Expiration Date. For
purposes of the Offer, the Purchaser will be deemed to have accepted for
payment, and thereby purchased, Shares properly tendered to the Purchaser and
not withdrawn, if, as and when the Purchaser gives oral or written notice to
the Depositary of its acceptance for payment of such Shares. Payment for Shares
accepted for payment pursuant to the Offer will be made by deposit of the
purchase price therefor with the Depositary, which will act as agent for
tendering shareholders for purposes of receiving payment from the Purchaser and
transmitting payment to tendering shareholders. Under no circumstances will
interest on the offer price for Shares be paid by the Purchaser by reason of
any delay in making such payment. Upon the deposit of funds with the Depositary
for the purpose of making payments to tendering shareholders, the Purchaser's
obligation to make such payment shall be satisfied and tendering

                                      -2-
<PAGE>

shareholders must thereafter look solely to the Depositary for payment of
amounts owed to them by reason of the acceptance for payment of Shares pursuant
to the Offer. In all cases, payment for Shares tendered and accepted for
payment pursuant to the Offer will be made only after timely receipt by the
Depositary of (a) certificates evidencing such Shares (or timely confirmation
of the book-entry transfer of such Shares into the Depositary's account at a
Book-Entry Transfer Facility (as defined in the Offer to Purchase)), pursuant
to the procedures set forth in Section 4 of the Offer to Purchase, (b) a
properly completed and duly executed Letter of Transmittal (or facsimile
thereof) with any required signature guarantees, or an Agent's Message (as
defined in the Offer to Purchase) in connection with a book-entry transfer, and
(c) any other documents required by the Letter of Transmittal.

The purchase price per Share payable to the Purchaser pursuant to the Offer
will not be reduced by the amount of the regular cash dividend of $.35 per
Share payable on August 15, 1997 to holders of record as of July 25, 1997. 

If, for any reason whatsoever, acceptance for payment of or payment for any
Shares tendered pursuant to the Offer is delayed, or the Purchaser is unable to
accept for payment or pay for Shares tendered pursuant to the Offer, then,
without prejudice to the Purchaser's rights set forth herein, the Depositary
may, nevertheless, on behalf of the Purchaser and subject to Rule 14e-1(c)
under the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
retain tendered Shares, and such Shares may not be withdrawn except to the
extent that the tendering shareholder is entitled to and duly exercises
withdrawal rights as described in Section 3 of the Offer to Purchase. Any such
delay will be accompanied by an extension of the Offer to the extent required
by law. The Purchaser will pay any stock transfer taxes incident to the
transfer to it of validly tendered Shares, except as otherwise provided in
Instruction 6 of the Letter of Transmittal, as well as any charges and expenses
of the Depositary and the Information Agent. If any tendered Shares are not
accepted for payment pursuant to the terms and conditions of the Offer for any
reason or are not paid for because of invalid tender, or if certificates are
submitted representing more Shares than are tendered, certificates representing
unpurchased or untendered Shares will be returned, without expense to the
tendering shareholder (or, in the case of Shares tendered by book-entry
transfer of such Shares into the Depositary's account at a Book-Entry Transfer
Facility as described in Section 4 of the Offer to Purchase, such Shares will
be credited to an account maintained within such Book-Entry Transfer Facility),
as soon as practicable following the expiration, termination or withdrawal of
the Offer and determination of the final results of proration. Except as
otherwise provided in Section 3 of the Offer to Purchase, tenders of Shares
made pursuant to the Offer are irrevocable. Shares tendered pursuant to the
Offer may be withdrawn at any time before the Expiration Date and, unless
theretofore accepted for payment by the Purchaser pursuant to the Offer, may
also be withdrawn at any time after September 16, 1997.

In order for a withdrawal to be effective, a written, telegraphic or facsimile
transmission notice of withdrawal must be timely received by the Depositary at
one

                                      -3-
<PAGE>

of its addresses set forth on the back cover of the Offer to Purchase. Any
notice of withdrawal must specify the name of the person having tendered the
Shares to be withdrawn, the number of Shares to be withdrawn and, if
certificates for Shares have been tendered, the name of the registered holder
of Shares as set forth in the tendered certificate, if different from that of
the person who tendered such Shares. If certificates for Shares
("Certificates") have been delivered or otherwise identified to the Depositary,
then, before the physical release of such Certificates, the serial numbers
shown on such Certificates must be submitted to the Depositary and the
signatures on the notice of withdrawal must be guaranteed by a firm which is a
bank, broker, dealer, credit union, savings association or other entity which
is a member in good standing of the Securities Transfer Agent's Medallion
Program (collectively, "Eligible Institutions"), unless such Shares have been
tendered for the account of any Eligible Institution. If Shares have been
delivered pursuant to the procedures for book-entry delivery as set forth in
Section 4 of the Offer to Purchase, any notice of withdrawal must also specify
the name and the number of the account at the appropriate Book-Entry Transfer
Facility to be credited with the withdrawn Shares and otherwise comply with
such Book-Entry Transfer Facility's procedures. Withdrawal of tenders of Shares
may not be rescinded, and any Shares properly withdrawn will be deemed not to
be validly tendered for purposes of the Offer. Withdrawn Shares may, however,
be retendered by repeating one of the procedures described in Section 4 of the
Offer to Purchase at any time before the Expiration Date. If the Purchaser
waives any material condition to the Offer, or amends the Offer in any other
material respect, the Purchaser will extend the Offer and disseminate
additional tender offer materials to the extent required to comply with the
Securities and Exchange Commission's interpretation of Rules 14d-4(c) and
14d-6(d) under the Exchange Act. The minimum period during which an offer must
remain open following material changes in the terms of the offer or information
concerning the offer, other than a change in price or a change in percentage of
securities sought, will depend upon the facts and circumstances, including the
relative materiality of the change in terms or information.

A request is being made to NYSEG pursuant to Rule 14d-5 of the Exchange Act for
use of NYSEG's shareholder lists and security position listings for the purpose
of disseminating the Offer to holders of Shares. The Offer to Purchase, the
related Letter of Transmittal and other relevant materials will be mailed to
record holders of Shares, and will be furnished to brokers, dealers, commercial
banks, trust companies and similar persons whose names, or the names of whose
nominees, appear on the shareholder lists or who are listed as participants in
a clearing agency's security position listing for subsequent transmittal to
beneficial owners of Shares by the Purchaser following receipt of such lists or
listings from NYSEG, or by NYSEG if it so elects.

The Offer to Purchase and the Letter of Transmittal, which will be mailed to
shareholders, contain important information which should be read carefully
before any decision is made with respect to the Offer.

         CALENERGY ANNOUNCES TENDER OFFER FOR 6,540,670 SHARES OF NYSEG
                        COMMON STOCK AT $24.50 PER SHARE

         OMAHA, Neb., July 15, 1997, CalEnergy Company, Inc. ("CalEnergy")
(NYSE, PSE AND LSE symbol: CE) announced today that its wholly owned subsidiary
CE Electric (NY), Inc. intends to commence a cash tender offer for 6,540,670
shares of the Common Stock of New York State Electric & Gas Corporation
("NYSEG")(NYSE symbol: NGE) at a price of $24.50 per share. Holders tendering
their shares will also be entitled to retain the regular 35(cent) dividend
payable in August.

         The purpose of the tender offer is to acquire shares which, together
with the shares of Common Stock currently owned by CalEnergy and its
affiliates, will represent 9.9% of the outstanding Common Stock of NYSEG, the
maximum percentage that can be acquired without certain federal and state
regulatory approvals. The tender offer is CalEnergy's first step toward the
intended acquisition of 100% of NYSEG's outstanding Common Stock.

         The tender offer is not subject to any financing condition. It is,
however, conditioned upon, among other things (i) at least 6,540,670 shares of
Common Stock being validly tendered and not withdrawn and (ii) the expiration
or termination of all waiting periods imposed by the Hart-Scott-Rodino
Antitrust Improvements Act.

         On July 10, 1997, David L. Sokol, the Chairman, Chief Executive
Officer and President of CalEnergy met with Wesley W. von Schack, the Chairman,
Chief Executive Officer and President of NYSEG to discuss the possibility of a
business combination between NYSEG and CalEnergy. Subsequent to that meeting,
Mr. von Schack called Mr. Sokol to inform him that the Board of Directors of
NYSEG, at a meeting on July 11, 1997, had determined that discussions of this
opportunity were not a priority and could not be conducted on the timely basis
which Mr. Sokol had outlined in their meeting.

         Accordingly, today Mr. Sokol sent the following letter to the Board of
Directors of NYSEG:

New York State Electric & Gas Corporation

Fax:  607-729-3318

Dear Wes:

I was disappointed to learn from you in our telephone call on Saturday, July
12th of your Board's decision that pursuing discussions with us concerning the
advantages of a possible combination of New York State Electric & Gas
Corporation ("NYSEG") and CalEnergy Company, Inc. ("CalEnergy") was not a
priority and could not be conducted on the timely basis which I outlined to you
in our meeting last week, on Thursday, July 10th. I might add that your Board's
reaction does not appear to be consistent with the clear impression you gave me
in our meeting last Thursday to the effect that a sale of NYSEG in the price
range we conceptually discussed was an alternative that you would seriously and
promptly consider and that you agreed it was in the best interests of your
shareholders that you do so.

Accordingly, after considered review of the publicly available information
concerning NYSEG, the CalEnergy Board has concluded that the potential
strategic and financial benefits to our companies' shareholders and other
concerned constituencies are compelling and should be pursued on an immediate
and serious basis. Our strong preference would be to work together with you and
the NYSEG Board to complete a negotiated transaction. However, in light of the
confusing messages we have received from you and your Board, CalEnergy is today
approaching your shareholders directly and announcing a cash tender offer to
acquire for $24.50 per share that number of shares of NYSEG common stock which,
together with the shares of NYSEG common stock which CalEnergy presently owns,
will represent 9.9% of the total number of shares of NYSEG common stock
outstanding. Holders tendering their shares will also be entitled to retain the
regular 35(cent) dividend payable in August. This tender offer is the first
step in the intended acquisition of 100% of NYSEG's common shares by CalEnergy.

As previously noted, we would much prefer to work together with you and your
Board to achieve a negotiated transaction. Accordingly, this letter sets forth
a specific proposal for consideration by you and your Board, together with a
brief 

<PAGE>

reiteration of the merger rationale which I shared with you at our meeting last
week.

Our specific merger proposal is to commence negotiations immediately to enter
into a consensual merger in which each outstanding share of NYSEG common stock
would be exchanged for $27.50 in cash. This cash price represents a premium of
31.74% above the NYSEG $20 7/8 per share NYSE closing price on June 30, 1997
(the day immediately preceding the day on which we first commenced our open
market purchases of NYSEG Common Stock). I would also note that the cash merger
price which we propose exceeds the up to 25% premium for NYSEG Common Stock
which you indicated, in our conceptual discussion during our meeting last
Thursday, might be appropriate in the context of a stock for stock merger of
NYSEG and CalEnergy.

As I informed you in our meeting last week, we have reviewed the regulatory
issues in detail and have fully underwritten financing offers in an amount
sufficient to complete the acquisition of 100% of NYSEG's common stock at the
price set forth above. The difference between our proposed consensual merger
price and our partial tender offer price reflects the shorter time interval and
increased certainty associated with the purchase of 9.9% of NYSEG's common
shares. The partial tender offer requires no regulatory approvals other than
expiration of the expected 15-day Hart-Scott-Rodino waiting period, as compared
to the estimated nine to twelve months for the regulatory approvals required to
complete the acquisition of 100% of NYSEG's common stock.

While NYSEG clearly possesses many strengths, you have publicly acknowledged
that both New York's energy industry generally and NYSEG specifically face a
number of serious, complex and immediate challenges. These include:

         o The New York Public Service Commission's restructuring proceedings
with respect to, among other things, (i) the lowering of the rates chargeable
by NYSEG and other New York utilities, (ii) the potential divestiture of
generation assets and (iii) the introduction of broadened competition;

         o Litigation by NYSEG concerning the unimplemented rate increases
approved in NYSEG's last rate case (August 1995);

         o NYSEG's potentially strandable above-market costs (which you have
publicly stated are more than twice the national average);

         o NYSEG's flat revenues over the last two years; and

         o The consistent underperformance of NYSEG's common stock since NYSEG
cut its dividend in October 1994.

                                      -2-
<PAGE>

CalEnergy welcomes the deregulation of the New York electric market and views
increased competition as positive and beneficial to ratepayers and the larger
New York community alike. We would expect to bring a helpful competitive focus
to NYSEG's transition to such an environment and in meeting the competitive
challenges which it faces.

CalEnergy, which has (according to analysts' consensus estimates) expected 1997
revenues in excess of $2 billion, traces its roots to the introduction of the
competitive electric generation industry within the United States and has
expanded and thrived in the competitive marketplace, both within the U.S. and
internationally.

As I described to you, CalEnergy's U.K. utility subsidiary, Northern Electric
plc (which is engaged in the distribution and supply of electricity to
approximately 1.5 million customers, primarily in Northeast England), brings us
direct experience, systems and skills acquired in the deregulated and
competitive U.K. electric and gas markets. We anticipate using these skills and
working closely with the New York Public Service Commission to provide rate
reductions for all NYSEG customers following the proposed merger, while
maintaining the safe and reliable service to which they are accustomed.

Consistent with CalEnergy's decentralized regional organization, we would
intend to maintain NYSEG as a separate operating business unit with its
existing corporate headquarters. We would also plan to reincorporate CalEnergy
in New York and grow NYSEG's business by participating aggressively in the
increasingly competitive New York electric market. This would ultimately make a
significant contribution to the local region's long-term ability to retain jobs
and attract new jobs and businesses. CalEnergy is a high growth company which
has increased its number of employees tenfold over the past 5 years and
provides worldwide opportunities in its numerous locations.

As I have previously detailed, we believe that our cash merger proposal, which
reflects a substantial premium over NYSEG's current market value, represents a
full and fair price for your shareholders. Moreover, our proposal would permit
your shareholders to realize this substantial cash value notwithstanding the
significant uncertainties facing NYSEG and its business today. To the extent
that you believe that your shareholders would view favorably an option to
receive CalEnergy shares or other forms of consideration in lieu of the cash
price we have proposed, we would be willing to consider that in the context of
a negotiated transaction.

Although we have found it necessary to go directly to your shareholders with
our partial tender offer and advise them of our merger proposal, my continuing
preference is to pursue this opportunity on a consensual basis with you and
NYSEG's board. We are available to meet with you immediately to discuss the
terms 

                                      -3-
<PAGE>

of this proposal. However, if you choose not to enter into discussions with us,
we believe, and we hope you will agree, that NYSEG's Board ought to permit
NYSEG's shareholders to freely decide for themselves on the merits of our offer
rather than taking any action which would hinder the shareholders' ability to
express their views.

I look forward to hearing from you soon.

Sincerely,


David L. Sokol
Chairman & Chief Executive Officer

cc:      Board of Directors of NYSEG Corp.
         c/o Mr. Wesley W. von Schack"

         Mr. Sokol added, "Our proposed business combination would yield many
benefits for NYSEG's customers and employees and the State of New York. We
welcome the various initiatives of the Governor's office, the legislature and
the New York Public Service Commission to introduce full competition to New
York's energy market. We fully expect that CalEnergy will be able to work
closely with the New York Public Service Commission to implement rate
reductions for all NYSEG customers, while providing them with the same safe and
reliable energy service to which they are accustomed. Lower rates would give
NYSEG an advantage in meeting the competitive challenges of the deregulating
energy market while contributing to New York's economic vitality and ability to
attract and retain jobs. We intend to reincorporate CalEnergy in New York and
maintain NYSEG as a distinct operating unit with its existing corporate
headquarters. CalEnergy is a growth company that has increased its number of
employees tenfold in the last five years."

CalEnergy Company, Inc.
302 South 36th St., Suite 400
Omaha, Nebraska 68131


Dear Sirs:

This letter confirms our understanding that CalEnergy Company, Inc.
("CalEnergy" or the "Company") has engaged Lehman Brothers Inc. ("Lehman
Brothers") and Credit Suisse First Boston Corporation ("CSFB") and their
relevant affiliates to act as its financial advisors with respect to the
proposed acquisition (the "Acquisition") by CE Electric (NY), Inc., a
subsidiary of CalEnergy, or by any other subsidiary or controlled affiliate of
CalEnergy, of all or a majority of the outstanding common stock or assets of
New York State Electric & Gas Corporation (the "Target").

In connection with this engagement, Lehman Brothers and CSFB will, at
CalEnergy's request:

(a)      undertake, in consultation with CalEnergy, a comprehensive review and
         financial analysis of the business, operations and prospects of the
         Target and provide advice to CalEnergy with respect to pricing,
         valuation, terms and conditions and structure of the Acquisition;

(b)      develop, in consultation with CalEnergy, a strategy to complete the
         Acquisition, including advising on structural and tactical aspects of
         the Acquisition, advising on strategic alternatives during the course
         of the Acquisition and providing advice on financing alternatives for
         the Acquisition;

(c)      be available at your request to meet with your Board of Directors to
         review the Acquisition and its financial implications and, if
         requested, render opinions as to

<PAGE>

CalEnergy Company, Inc.
July 14, 1997
Page 2


         the fairness to CalEnergy, from a financial point of view, of the
         consideration to be paid by CalEnergy in the Acquisition;

(d)      assist in the negotiations and communications with the various
         constituencies to the transaction including the Target's management,
         Board of Directors, legal and financial advisors and major
         shareholders, as well as relevant regulatory authorities; and

(e)      assist in the closing of the Acquisition.

In connection with this engagement, the Company will furnish Lehman Brothers
and CSFB with all information concerning the Company and, to the extent
available to the Company, the Target, which Lehman Brothers or CSFB reasonably
requests, and will provide Lehman Brothers and CSFB with reasonable access to
the Company and its officers, directors, accountants and counsel, it being
understood that Lehman Brothers and CSFB will rely solely upon such information
provided by the Company and the Target and their officers, directors,
accountants and counsel without assuming any responsibility for independent
investigation or verification thereof; in each case consistent with providing
assistance in the comprehensive due diligence review described above.

Where in the course of this assignment the Company provides Lehman Brothers or
CSFB with confidential information, except as otherwise required by applicable
law, rule, regulation or legal process, Lehman Brothers or CSFB, as the case
may be, undertakes to keep such information confidential and make reasonable
efforts to ensure that its relevant employees and advisors shall agree to
comply with the terms specified herein. Lehman Brothers and CSFB each shall be
responsible for any breach of the terms hereof by itself and its employees.
Prior to making any required disclosure, to the extent practicable and
permitted by law, Lehman Brothers or CSFB, as applicable, shall provide the
Company with prompt written notice of any such requirement so that the Company
may seek a protective order or other appropriate remedy. For the purpose of
these undertakings, information shall not be deemed to be confidential if (a)
it is freely available to the public (other than by breach of this agreement)
or (b) it has been made available to Lehman Brothers or CSFB from a source
other than the Company or the Company's agents acting on the Company's
instructions, unless such information was obtained in breach of a
confidentiality agreement. Lehman Brothers and CSFB will use such information
only for the purposes of its engagement in connection with the Acquisition.

As compensation for our services hereunder, the Company agrees to pay Lehman
Brothers and CSFB an aggregate transaction fee of $8,500,000 (the "Transaction
Fee"), of which (i) $250,000 is payable upon the filing of a pre-merger
notification under the

<PAGE>

CalEnergy Company, Inc.
July 14, 1997
Page 3


Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, in connection
with the Acquisition, (ii) $750,000 is payable upon the earlier to occur of (x)
the execution of a merger or similar agreement between the Target and CalEnergy
or a subsidiary or affiliate of CalEnergy providing for a merger or other
business combination or strategic partnership with the Target or the purchase
of a majority of the common stock or assets of the Target in connection with
the Acquisition and (y) the delivery by Lehman Brothers or CSFB of an opinion
pursuant to this engagement letter, and (iii) $7,500,000 is payable upon the
closing of the Acquisition. If discussions regarding the Acquisition of the
Target are terminated or such Acquisition of the Target does not occur for any
reason whatsoever, then the Company shall pay to Lehman Brothers and CSFB an
additional fee equivalent to 10% of any profits earned by the Company or any of
its affiliates in connection with any sales or dispositions of securities of
the Target, after recovery of all costs related to the purchase and sale of
such securities. Each portion of the Transaction Fee or other fee which becomes
payable pursuant to this engagement letter shall be allocated 60% to Lehman
Brothers and 40% to CSFB; provided, however, that in the event that either (but
not both) of Lehman Brothers or CSFB elects to terminate this engagement
letter, then 100% of any portion of the Transaction Fee and any other fee which
thereafter becomes payable shall be payable to CSFB or Lehman Brothers,
respectively; provided, further, however, that in the event that either (but
not both) of Lehman or CSFB elects to terminate this engagement letter and the
Company engages another financial advisor with respect to the Acquisition, then
the Company and the non- terminating financial advisor shall agree on an
equitable allocation of the Transaction Fee and any other fee which thereafter
becomes payable between the non-terminating financial advisor and such other
financial advisor.

In addition, Lehman Brothers and CSFB will be reimbursed for their respective
reasonable out-of-pocket expenses incurred in connection with their roles
hereunder, including the reasonable fees and expenses of their legal counsel,
technical consultants and any other advisors retained by Lehman Brothers or
CSFB with the prior approval of the Company, which approval shall not be
unreasonably withheld. The Company acknowledges that Lehman Brothers and CSFB
have retained Skadden, Arps, Slate, Meagher & Flom LLP ("Skadden Arps") to act
as legal counsel in connection with this engagement. Lehman Brothers and CSFB
acknowledge that Skadden Arps is also acting as legal counsel to the Company
with respect to certain regulatory matters in connection with the Acquisition.

If either Lehman Brothers or CSFB is requested to render opinions, the nature
and scope of any analyses as well as the form and substance of the opinions
shall be such as Lehman Brothers or CSFB, as the case may be, deems appropriate
and as is customary

for transactions of this type. If requested by you, the opinions shall be
delivered in writing.

No advice or opinion rendered by either of Lehman Brothers or CSFB, whether
formal or informal, may be disclosed, in whole or in part, or summarized,
excerpted from or otherwise referred to without its prior written consent,
which consent shall not be unreasonably withheld. In addition, neither Lehman
Brothers nor CSFB may otherwise be referred to without its prior written
consent, which consent shall not be unreasonably withheld. If requested by
Lehman Brothers or CSFB, the Company shall include a mutually acceptable
reference to Lehman Brothers or CSFB, as the case may be, in any press release
or other public announcement made by the Company regarding the matters
described in this letter.

Since Lehman Brothers and CSFB will be acting on behalf of the Company in
connection with their engagement hereunder, it is a condition of such
engagement that the Company enter into a separate indemnification agreement in
the form attached hereto, providing for the indemnification by the Company of
Lehman Brothers, CSFB and certain related persons and entities. Such
indemnification agreement is an integral part of this letter and shall remain
in full force and effect regardless of any completion, modification or
termination of Lehman Brothers' or CSFB's engagement hereunder.

The Company further understands that if Lehman Brothers or CSFB or any of their
respective affiliates agrees to arrange the financing for the Acquisition or to
act for the Company as an underwriter or placement agent in connection with the
issuance of securities by the Company or in any other formal additional
capacity (including as dealer-manager in any tender offer), then the terms of
any such additional engagements shall be embodied in one or more separate
written agreements, containing such provisions and terms as shall be finally
agreed upon by the parties thereto at such time. This agreement does not
constitute a commitment by Lehman Brothers or CSFB to arrange financing for the
Acquisition or to act as underwriter or placement agent or in any other formal
additional capacity. Such a commitment will arise only under a separate written
agreement, it being understood that, except as otherwise mutually agreed by the
parties hereto, any engagement to provide services to the Company under such a
separate written agreement need not be apportioned between Lehman Brothers and
CSFB.

Each of Lehman Brothers' and CSFB's engagement hereunder may be terminated at
any time, with or without cause, by Lehman Brothers or CSFB, respectively, or
by the Company, in each case upon written notice thereof to the other parties;
provided, however, that in the event of any termination of Lehman Brothers' or
CSFB's engagement hereunder (except as a result of Lehman Brothers' or CSFB's
gross negligence or

material breach of contract), Lehman Brothers or CSFB, as the case may be, will
continue to be entitled to its share of the full Transaction Fee provided for
herein in the event that at any time prior to the expiration of two years after
such termination the Company or any controlled affiliate consummates the
Acquisition of the Target and Lehman Brothers and CSFB shall continue to be
entitled to the full amount of any other fee provided for herein in the event
that at any time prior to the expiration of two years after such termination
the circumstances giving rise to such fee shall occur; provided, further, that
any termination of Lehman Brothers' and/or CSFB's engagement hereunder shall
not affect the Company's obligation to pay the accrued and unpaid fees and
expenses to the extent provided for herein and to indemnify Lehman Brothers,
CSFB and certain related persons and entities as provided in the separate
letter agreement referred to above.

This letter and the indemnification agreement may not be amended or modified
except in writing. This agreement has been made solely for the benefit of the
Company, Lehman Brothers and CSFB and the Indemnified Persons referred to in
the attached indemnification agreement and their respective heirs, successors
and assigns, and no other person or entity shall acquire or have any rights
under or by virtue of this agreement.

In connection with this engagement, Lehman Brothers and CSFB are acting as
independent contractors and not in any other capacity, with duties owing solely
to the Company. All aspects of the relationship created by this agreement shall
be governed by and construed in accordance with the laws of the State of New
York, without regard to conflicts of law principles thereof. The rights and
obligations of each of Lehman Brothers and CSFB set forth herein are several
and not joint.

CALENERGY COMPANY, INC.


By: /s/ Steven A. McArthur
   -------------------------------
   Name: Steven A. McArthur
   Title: Senior Vice President

<PAGE>

To:      Lehman Brothers Inc.                                     July 14, 1997
         Three World Financial Center

         Credit Suisse First Boston Corporation
         Eleven Madison Avenue
         New York, New York 10010


         In connection with your engagement (the "engagement") to advise and
assist CalEnergy Company, Inc. (the "Company" or "we") with the proposed
acquisition of New York State Electric & Gas Corporation, we agree to indemnify
and hold harmless Lehman Brothers Inc. ("Lehman Brothers") and its affiliates,
Credit Suisse First Boston Corporation ("CSFB") and its affiliates (each of
Lehman Brothers and CSFB is referred to herein individually as an "Advisor"
and, collectively, as the "Advisors"), the respective directors, officers,
partners, agents and employees of Lehman Brothers, CSFB and their affiliates,
and each other person, if any, controlling Lehman Brothers, CSFB or any of
their affiliates (collectively, "Indemnified Persons"), from and against, and
we agree that no Indemnified Person shall have any liability to the Company
for, any losses, claims, damages or liabilities (including actions or
proceedings in respect thereof) (collectively "Losses") related to or arising
out of the engagement or your performance thereof, except that this clause
shall not apply to any Losses suffered by any Advisor (or its related
Indemnified Persons) to the extent that they are finally judicially determined
or agreed to have resulted from the bad faith, willful misconduct, or gross
negligence of such Advisor. If such indemnification is for any reason not
available to any Indemnified Person or is insufficient to hold such Indemnified
Person harmless, we agree to contribute to the Losses involved in such
proportion as is appropriate to reflect the relative benefits received (or
anticipated to be received) by us and by such Indemnified Person (or its
related Advisor) with respect to the engagement or, if such allocation is
judicially determined unavailable, in such proportion as is appropriate to
reflect other equitable considerations such as the relative fault of us on the
one hand and of such Indemnified Person (or its related Advisor) on the other
hand, provided, however, that, to the extent permitted by applicable law, no
Indemnified Person (together with its related Indemnified Persons and related
Advisor) shall be responsible for amounts which in the aggregate are in excess
of the amount of all fees actually received by such Indemnified Person (or its
related Advisor) and its affiliates from us and our affiliates in connection
with the engagement. Relative benefits to us, on the one hand, and any
Indemnified Person, on the other hand, with respect to the engagement shall be
deemed to be in the same proportion as (i) the total value paid or proposed to
be paid or received or proposed to be received by us or our affiliates or our
security holders, as the case may be, pursuant to the transaction(s), whether
or not consummated, contemplated by the engagement bears to (ii) all fees paid
or proposed to be paid to such Indemnified Person (or its related Advisor) and
its affiliates by us and our affiliates in connection with the engagement.

<PAGE>

         We will reimburse each Indemnified Person for all reasonable expenses
(including without limitation reasonable fees and disbursements of counsel and
expenses incurred in connection with preparing for and responding to third
party subpoenas) as they are incurred by such Indemnified Person in connection
with investigating, preparing for or defending any action, claim or proceeding
("Action") referred to above (or enforcing this agreement or any related
engagement agreement), whether or not in connection with pending or threatened
litigation in which any Indemnified Person is a party. Lehman Brothers or CSFB
will promptly notify us of any Actions or potentially indemnifiable events
hereunder, but the failure so to notify shall not relieve us of any liability
hereunder except to the extent we have been materially prejudiced thereby. In
addition, Lehman Brothers and CSFB will cause all Indemnified Persons to comply
with all reasonable instructions given by us, and to provide us with reasonable
assistance in resolving any Action. We further agree that we will not, without
your prior written consent, settle or compromise or consent to the entry of any
judgment in any pending or threatened Action in respect of which
indemnification may be sought hereunder (whether or not an Indemnified Person
is a party therein) without the consent of each Indemnified Person, such
consent not to be unreasonably withheld.

         Our obligations hereunder shall be in addition to any rights that any
Indemnified Person may have at common law or otherwise. We acknowledge that in
connection with the engagement you are acting as an independent contractor with
duties owing solely to us. YOU HEREBY AGREE, AND WE HEREBY AGREE ON OUR OWN
BEHALF AND, TO THE EXTENT PERMITTED BY APPLICABLE LAW, ON BEHALF OF OUR
SECURITY HOLDERS, TO WAIVE ANY RIGHT TO TRIAL BY JURY WITH RESPECT TO ANY
CLAIM, COUNTER-CLAIM OR ACTION ARISING OUT OF THE ENGAGEMENT, YOUR PERFORMANCE
THEREOF OR THIS AGREEMENT.

<PAGE>

         The provisions of this agreement shall apply to the engagement
(including related activities prior to the date hereof) and any modification
thereof and shall remain in full force and effect regardless of the completion
or termination of the engagement. This agreement and any other agreements
relating to the engagement shall be governed by and construed in accordance
with the laws of the State of New York, without regard to conflicts of law
principles.


                                            Very truly yours,
