ITEM 5.  OTHER EVENTS.

         TENDER OFFER; PROPOSED MERGER; SUBSEQUENT OFFER. On August 6, 1997,
CalEnergy Company, Inc. ("CalEnergy") announced that it had executed fully
underwritten financing commitments for a consensual merger (the "Proposed
Merger") with New York State Electric & Gas Corporation ("NYSEG") or for a
tender offer (the "Subsequent Offer") and related merger that may be commenced
subsequent to the pending Tender Offer (as defined below).

         On July 15, 1997, CalEnergy advised NYSEG of its intention to
commence a tender offer (the "Tender Offer") to acquire that number of shares
("NYSEG Shares") of common stock, par value $6.66 2/3 per share, of NYSEG
which, together with the NYSEG Shares beneficially owned by CalEnergy, would
represent 9.9% of the total number of NYSEG Shares outstanding. On July 18,
1997 CE Electric (NY), Inc., a wholly owned subsidiary of CalEnergy (the
"Purchaser"), commenced the Tender Offer. The $24.50 per NYSEG Share
consideration offered pursuant to the Tender Offer represents a premium of
approximately 17.4% over the closing price of the NYSEG Shares on the New York
Stock Exchange on June 30, 1997, the day an affiliate of CalEnergy commenced
purchases of NYSEG Shares in the open market. The Tender Offer is scheduled to
expire at 12:00 midnight, New York City time, on Thursday, August 14, 1997,
unless extended. The Tender Offer is not subject to any financing condition.

         CalEnergy also advised NYSEG on July 15, 1997 that it was prepared to
negotiate a consensual merger (the "Proposed Merger") in which each
outstanding NYSEG Share would be exchanged for $27.50 in cash. The $27.50 cash
price represented a premium of approximately 31.74% over the closing price of
the NYSEG Shares on June 30, 1997. CalEnergy and the Purchaser intend to
continue to attempt to seek to negotiate the Proposed Merger with NYSEG.

         If NYSEG's Board of Directors continues to refuse to negotiate with
CalEnergy and the Purchaser, CalEnergy and the Purchaser currently intend,
following consummation of the Tender Offer, to commence the Subsequent Offer
to acquire all of the outstanding NYSEG Shares it does not then own. The
alternatives being considered by CalEnergy and the Purchaser include the
Subsequent Offer for all of such NYSEG Shares. The Purchaser currently
intends, as soon as practicable following consummation of the Subsequent
Offer, to seek to have NYSEG consummate a merger or similar business
combination with the Purchaser (the "Subsequent Merger"), pursuant to which
each outstanding NYSEG Share would be converted into the right to receive cash
in the same amount as received per NYSEG Share in the Subsequent Offer, and
NYSEG would become a wholly owned subsidiary of CalEnergy. The Subsequent
Offer would be expected to be subject to a number of conditions to which the
Tender Offer is not subject, including the receipt of all required regulatory
approvals and certain other conditions.

         SOURCE AND AMOUNT OF FUNDS. The Purchaser estimates that the total
amount of funds required to purchase the NYSEG Shares in the Tender Offer will
be approximately $165 million. The Purchaser will obtain such funds through a
capital contribution by CalEnergy from available cash.


                                     -2-
<PAGE>


         The Purchaser estimates that, following consummation of the Tender
Offer, funds in an aggregate amount of approximately $1.7 billion would be
required to purchase the NYSEG Shares in the Proposed Merger at the proposed
merger price of $27.50 per NYSEG Share. This estimate is based on the number
of NYSEG Shares outstanding as reported in NYSEG's Quarterly Report on Form
10-Q for the fiscal quarter ended March 31, 1997. The Purchaser expects to
obtain such funds through various borrowings by the Purchaser from commercial
banks and through capital contributions to the Purchaser by CalEnergy.
CalEnergy presently expects that the source of funds for its capital
contributions to Purchaser will include the proceeds of the Offerings (as
defined below), various borrowings by CalEnergy and CalEnergy's corporate
funds. CalEnergy presently plans, subject to market conditions, to issue
certain equity, equity-related and debt securities in public and/or private
offerings (the "Offerings") on a prompt basis, the equity and equity-related
component of which is not currently expected to exceed approximately $550
million. On August 5, 1997, CalEnergy and certain subsidiary trusts filed a
shelf registration statement relating to common stock, preferred stock and
debt securities, which may be issued from time to time for various purposes in
amounts up to $1.5 billion in the aggregate.

         THE PURCHASER CREDIT FACILITIES. CalEnergy and the Purchaser have
entered into a senior bank financing commitment letter agreement with CSFB
(the "CSFB Commitment Agreement") providing for a binding commitment by CSFB
to provide up to $1 billion under a term loan and revolving credit facility to
the Purchaser in connection with consummating the Proposed Merger or the
Subsequent Offer and the Subsequent Merger, to provide for the payment of
transaction expenses and to provide working capital for the Purchaser and
NYSEG.

         The CSFB Commitment Agreement contemplates (i) a 5-year term loan
facility of up to $650 million (the "Term Loan Facility"); and (ii) a 5-year
revolving credit facility of up to $350 million (the "Revolving Credit
Facility" and, together with the Term Loan Facility, the "Purchaser Credit
Facilities").

         The proceeds of the Purchaser Credit Facilities shall be used to (i)
finance the acquisition of NYSEG Shares pursuant to the Proposed Merger or the
Subsequent Offer and the Subsequent Merger at a price of up to $27.50 per
NYSEG Share; (ii) refinance existing indebtedness of NYSEG after giving effect
to the Proposed Merger or the Subsequent Merger; (iii) pay related fees and
expenses in connection with the Proposed Merger or the Subsequent Offer and
the Subsequent Merger; and (iv) provide for the working capital and general
corporate needs of the Purchaser, NYSEG and their subsidiaries.

         The Purchaser Credit Facilities will be secured by (i) the capital
stock of the Purchaser; (ii) the NYSEG Shares owned by the Purchaser or any of
its affiliates; and (iii) certain other properties and assets of the
Purchaser.

         Interest on loans borrowed under the Purchaser Credit Facilities will
be payable, at the election of the borrowers, at either a Base Rate (the
higher of CSFB's announced prime commercial lending rate or the daily federal
funds rate plus 0.50%) or Eurodollar Rate (the rate for U.S. Dollar deposits
as reported by the British Bankers' Association as adjusted for applicable
reserves), plus interest margins determined according to a ratings grid based
on the Purchaser's senior unsecured debt rating.

<PAGE>



         CSFB's commitment under the Purchaser Credit Facilities will
terminate on (x) October 15, 1997 unless definitive credit documentation
mutually acceptable to the parties has been executed and delivered, and (y)
December 31, 1998, unless the initial borrowing thereunder has occurred on or
prior to such date.

         The obligations of CSFB under the CSFB Commitment Agreement are
subject, among other things, to the following conditions: (i) the preparation,
execution and delivery of mutually acceptable loan documentation; (ii) the
absence of certain material adverse changes; (iii) CSFB's reasonable
satisfaction with its due diligence with respect to the Proposed Merger or the
Subsequent Offer and the Subsequent Merger; (iv) not less than 66-2/3% of the
NYSEG Shares being owned by the Purchaser or having been tendered and not
withdrawn pursuant to the Subsequent Offer; and (v) execution of satisfactory
documentation providing for the Proposed Merger or the Subsequent Offer and
the Subsequent Merger.

         The definitive documentation relating to the Purchaser Credit
Facilities will contain representations, warranties, covenants, events of
default and conditions customary for transactions of this size and type.
CalEnergy has agreed to pay certain fees to CSFB with respect to the Purchaser
Credit Facilities which, in the aggregate, are not material to the
transactions described herein.

         THE AMENDED AND RESTATED $250 MILLION CREDIT FACILITY. CalEnergy has
entered into a senior bank financing commitment letter agreement with CSFB and
Lehman Commercial Paper, Inc. ("Lehman") providing binding commitments to
amend and restate its existing $100 million revolving credit facility to
provide for an unsecured revolving loan and standby letter of credit facility
in the aggregate amount of $250 million (the "$250 Million Credit Facility").

         The term of the $250 Million Credit Facility will be three years,
extendible on the second and third anniversaries of the closing for a period
of one year, at CalEnergy's request with the consent of the lending banks.

         Loans under the $250 Million Credit Facility will bear interest, at
CalEnergy's election, at either (i) a Base Rate equal to the higher of the
rate announced from time to time by CSFB as its prime commercial lending rate
or the daily federal funds rate plus .50%, or (ii) a Eurodollar Rate (the rate
for U.S. Dollar deposits as reported by the British Bankers' Association as
adjusted for applicable reserves), plus, in each case, an interest margin
based on the credit rating of CalEnergy's senior unsecured long-term debt.

         The commitment to provide the $250 Million Credit Facility is subject
to customary conditions for a facility of this size and type, including
without limitation, (a) the preparation, execution and delivery of mutually
acceptable loan and credit documentation; and (b) the absence of any material
adverse change in the business, assets, operations, properties, prospects or
condition (financial or otherwise) of CalEnergy and its subsidiaries, taken as
a whole, since December 31, 1996. The commitment will terminate on October 15,
1997 unless definitive credit documentation mutually acceptable to the parties
has been executed and delivered.


                                     -4-
<PAGE>


         The definitive documentation relating to the $250 Million Credit
Facility will contain representations, warranties, covenants (including,
without limitation, restrictions on the use of net cash proceeds from asset
dispositions, limitations on the incurrence of debt and restrictions on
acquisitions), events of default and conditions customary for transactions of
this size and type. CalEnergy has agreed to pay certain fees to CSFB and
Lehman with respect to the $250 Million Credit Facility which, in the
aggregate, are not material to the transactions described herein.

         THE NEW $150 MILLION CREDIT FACILITY. CalEnergy has entered into a
senior bank financing commitment letter agreement with CSFB and Lehman
providing a binding commitment for an unsecured revolving credit facility in
the aggregate amount of $150 million (the "$150 Million Credit Facility").

         The term of the $150 Million Credit Facility will be three years,
extendible on the second and third anniversaries of the closing for a period
of one year, at CalEnergy's request with the consent of the lending banks.

         Interest on loans under the $150 Million Credit Facility will be
payable at spreads which vary depending on CalEnergy's senior unsecured
long-term debt ratings. The spreads vary from 0.75% to 2.25% above Eurodollar
Rate (the rate for U.S. Dollar deposits as reported by the British Bankers'
Association as adjusted for applicable reserves) or from 0.00% to 1.00% above
Base Rate (the higher of CSFB's announced prime commercial lending rate or the
daily federal funds rate plus 0.50%). CalEnergy may elect to incur loans at
either Eurodollar Rate or Base Rate.

         The commitment to provide the $150 Million Credit Facility is subject
to customary conditions for a facility of this size and type, and conditions
to be agreed upon, if applicable, including without limitation, (a) the
preparation, execution and delivery of mutually acceptable loan and credit
documentation; and (b) the absence of any material adverse change in the
business, assets, operations, properties, prospects or condition (financial or
otherwise) of CalEnergy and its subsidiaries, taken as a whole, since December
31, 1996. The commitment will terminate on August 5, 1998, unless definitive
credit documentation mutually acceptable to the parties has been executed and
delivered.

         The definitive documentation relating to the $150 Million Credit
Facility will contain representations, warranties, covenants (including,
without limitation, restrictions on the use of net cash proceeds from asset
dispositions, limitations on the incurrence of debt and restrictions on
acquisitions), events of default and conditions customary for transactions of
this size and type. CalEnergy has agreed to pay certain fees to CSFB and
Lehman with respect to the $150 Million Credit Facility which, in the
aggregate, are not material to the transactions described herein.

         THE BRIDGE FACILITY. CalEnergy presently plans, subject to market
conditions, to issue securities in the Offerings on a prompt basis. To the
extent that the net proceeds of the Offerings result in less than $500 million
of net proceeds to CalEnergy, CalEnergy would then require bridge loan
financing. In order to provide for such bridge financing, if required,
CalEnergy has entered into a fully underwritten bridge loan financing
commitment letter agreement with CSFB First Boston ("CSFB") and LB I Group
Inc. ("LBI") providing for a binding commitment by 


                                     -5-

<PAGE>

CSFB and LBI to provide an unsecured bridge loan facility for an amount of up
to $500,000,000, less the amount of net proceeds, if any, raised in the
Offerings (the "Bridge Facility").

         The commitment shall terminate 364 days after the execution of the
Bridge Facility commitment letter agreement unless the lenders shall have
extended the term in writing. Interest on the bridge loans, if any, borrowed
under the Bridge Facility would be payable at a rate per annum equal to the 3
Month Adjusted LIBOR (LIBOR plus statutory reserves) plus the "Applicable
Spread". If the Bridge Facility were to be funded, then the Applicable Spread
would initially be 600 basis points and would increase by 100 basis points at
the end of the six month period following the funding of the Bridge Facility,
if applicable, and by an additional 50 basis points at the end of each three
month period thereafter, if applicable, until maturity, subject to certain
limitations. In the event that the LIBOR rate cannot be determined or a LIBOR
rate loan may not be lawfully maintained by a lender, then interest shall
accrue at the Base Rate (the higher of CSFB's announced prime commercial
lending rate less 200 basis points and the federal funds effective rate plus
50 basis points) plus the Applicable Spread.

         If the Bridge Facility were to be funded, then the bridge loans would
mature 364 days thereafter.

         CSFB's and LBI's commitment to provide the Bridge Facility is subject
to certain customary conditions including (i) the execution of satisfactory
documentation providing for the Proposed Merger or the Subsequent Offer and
the Subsequent Merger; (ii) not less than 66-2/3% of the NYSEG Shares being
owned by the Purchaser or having been tendered and not withdrawn pursuant to
the Subsequent Offer; (iii) the absence of any material adverse change in the
business, assets, operations, properties, prospects or condition (financial or
otherwise) of CalEnergy and its subsidiaries, taken as a whole, or NYSEG and
its subsidiaries, taken as a whole, since December 31, 1996; and (iv) mutually
satisfactory definitive documentation being executed. The definitive
documentation relating to the Bridge Facility is expected to contain
representations, warranties, covenants, events of default and conditions
customary for transactions of this size and type. CalEnergy has agreed to pay
certain fees to CSFB and LBI with respect to the Bridge Facility which, in the
aggregate, are not material to the transactions described herein.

         Miscellaneous. The foregoing description of each of the Bridge
Facility commitment letter agreement, the $150 Million Credit Facility
commitment letter agreement, the $250 Million Credit Facility commitment
letter agreement and the CSFB Commitment Agreement is qualified in its
entirety by reference to the text thereof filed as an exhibit hereto.

                CALENERGY EXECUTES FULLY UNDERWRITTEN FINANCING
                     COMMITMENTS FOR PROPOSED NYSEG MERGER

         New York, New York, August 6, 1997, CalEnergy Company, Inc.
("CalEnergy") (NYSE, PSE and LSE symbol: CE) and its wholly owned subsidiary,
CE Electric (NY), Inc. ("CENY") announced today the signing of fully
underwritten binding financing commitment agreements with Credit Suisse First
Boston and Lehman Brothers to fund CalEnergy's purchase of 100% of the shares
of common stock ("Shares") of New York State Electric & Gas Corporation
("NYSEG") (as well as to fund transaction costs and working capital
requirements) pursuant to CalEnergy's proposed $27.50 per Share merger
proposal.

         Fully underwritten binding commitment agreements in an amount
totaling up to $1.9 billion have been entered into by CalEnergy and CENY as
follows:

            o  New and amended CalEnergy revolving credit facilities in the
               aggregate amount of $400 million.
            o  Up to a $500 million CalEnergy bridge financing facility, if
               required.
            o  Up to $1.0 billion of CENY credit facilities comprised of a
               $650 million five-year term loan and a $350 million five-year
               revolving credit facility.

         On August 5, 1997, CalEnergy and certain affiliated capital funding
trusts also filed with the Securities and Exchange Commission a shelf
registration statement covering up to $1.5 billion of common stock, preferred
stock and debt securities which may be sold from time to time for various
purposes. CalEnergy presently intends to effect certain equity and debt
securities offerings on a prompt basis (subject to market conditions), in
which case drawings under the bridge facility may not be required. The equity
component of such future offerings is not currently expected to exceed
approximately $550 million.

         CalEnergy's Chairman and CEO, David L. Sokol, commented, "We are
pleased to have executed binding commitments to provide the necessary
financing for our proposed merger with NYSEG at a $27.50 per common share
purchase price and to fund related transaction costs and provide working
capital for CENY and NYSEG. These binding commitments should provide us with
all the financing flexibility necessary to complete the acquisition of 100% of
the NYSEG shares on the terms we have previously proposed. We intend to
proceed in a determined fashion to pursue the NYSEG acquisition. We look
forward to the successful consummation of our pending cash tender offer for
9.9% of the NYSEG common shares as scheduled on August 14, 1997, and we very
much hope to commence merger negotiations with NYSEG's management on a
similarly prompt timetable."

         On July 18, 1997, CENY formally commenced a cash tender offer for
6,540,670 common shares of NYSEG at a price of $24.50 per share. The tender
offer is scheduled to expire at 12:00 midnight, New York City time on
Thursday, August 14, 1997, unless extended.

         CalEnergy, which manages and owns interests in over 5,000 net MW of
power generation facilities in operation, construction and development
worldwide, currently operates 20 generating facilities and also supplies and
distributes electricity to 1.5 million customers.

                  Re:      Commitment Letter

Dear Gentlemen:

                  You have advised Credit Suisse First Boston ("CSFB") that a
newly formed wholly-owned subsidiary of CalEnergy Company, Inc., a Delaware
corporation ("CE"), CE Electric (NY), Inc., a New York corporation ("Bidco"),
intends to acquire the issued and outstanding shares of common stock (the
"Shares") (calculated on a fully-diluted basis) of New York State Electric &
Gas Corporation, a New York corporation ("NYSEG") by means of a takeover bid
(the "Tender Offer") and subsequent merger pursuant to which a subsidiary of
Bidco will be merged with and into NYSEG (the "Merger") pursuant to a merger
agreement with NYSEG (the "Merger Agreement"), and as a result of the Merger,
NYSEG shall become a direct or indirect wholly-owned subsidiary of CE. The
Tender Offer and the Merger are referred to herein as the "Transactions."

                  CSFB further understands that senior bank financing (the
"Senior Financing") is required by Bidco (with respect to the Term Loan

                  CSFB also understands that the proceeds from the Credit
Facility shall be used to finance the acquisition of Shares pursuant to the
Tender Offer and Merger Agreement, to refinance existing indebtedness of NYSEG
after giving effect to the Merger, to pay consideration in connection with the
Merger, to pay related fees and expenses in connection with the Transactions
and to provide for the working capital and general corporate needs of Bidco,
NYSEG and their subsidiaries.

                  You have further advised us that in addition to the Credit
Facility Bidco will require equity proceeds in connection with the Transactions
in an amount which, when aggregated with the proceeds of the Credit Facility,
will be sufficient to enable Bidco to fund the purchase all of the Shares and
costs associated with the Transactions and for refinancing of certain
obligations, which equity proceeds will be contributed by CE through CE's cash
on hand and from the proceeds of debt and equity of CE, all as more
specifically set forth in certain letters, dated as of the date hereof, among
CSFB, other parties and CE ) (the "Debt/Equity Financing").

                  We are pleased to confirm that CSFB hereby commits to provide
the entire Credit Facility on the terms and conditions set forth herein and in
the Term Sheet and on such other terms and conditions as CSFB deems reasonably
necessary or appropriate in the context of the Senior Financing and the
proposed Transactions. All aspects of the Senior Financing and the proposed
Transactions including, without limitation, the Tender Offer, the Merger, the
Merger Agreement, and all documentation relating thereto, shall be in form and
substance reasonably satisfactory to CSFB. Please note that the terms and
conditions of CSFB's commitment and undertakings hereunder are not limited to
those set forth herein or in the Term Sheet. Those matters that are not covered
or made clear herein or in the Term Sheet are subject to mutual agreement of

matter which is inconsistent in a material manner with any information or other

sole arranger and administrative agent. You agree that no other entity shall
have any title with respect to the Senior Financing or shall be appointed in
the capacity of agent, co-agent or arranger without the mutual consent of CE

documentation for the Senior Financing, to syndicate all or part of our
commitment to one or more financial institutions or other "accredited
investors" (as defined in Regulation D of the Securities Act of 1933, as
amended) reasonably acceptable to CE, Bidco and CSFB (collectively, the
"Lenders" and each a "Lender") that will become parties to such definitive
documentation pursuant to a syndication to be managed and controlled in all
respects by CSFB (including, without limitation, as to the timing of all offers
to potential Lenders and acceptance of commitments, the amounts offered and the
compensation provided to potential Lenders) and that CSFB would act as the sole
and exclusive agent for such Lenders (in such capacity, the "Agent"). By your
acceptance hereof, you agree both before and after the closing of the Senior
Financing to actively assist us in achieving a syndication that is satisfactory
to us, which assistance shall include but not be limited to: (a) making senior
management and representatives of CE, Bidco and its controlled affiliates
available to participate in one or more meetings with potential Lenders at such
times and places as CSFB may reasonably request; (b) using all reasonable
efforts to ensure that the syndication efforts benefit from CE's and its
controlled affiliates' existing banking relationships; and (c) providing CSFB
with information reasonably requested to complete the syndication successfully,
including, without limitation, the preparation of such offering materials as
CSFB may reasonably request.

                  Each of CE and Bidco hereby represents, warrants and
covenants that (x) all information (other than projections) and data concerning
CE, Bidco and their subsidiaries which has been or is hereafter furnished or
otherwise made available to CSFB by CE or Bidco or any of their representatives
in connection with the transactions contemplated hereby is and will be complete

fact or omit to state a material fact necessary in order to make the statements
contained therein not misleading in light of the circumstances under which such
statements are made (it being understood by CSFB that any representation by CE
and Bidco as to any information relating to NYSEG and its subsidiaries is made
to your best knowledge) and (y) all financial projections concerning CE, Bidco
and their subsidiaries or the Transactions which have been or are hereafter
made available to CSFB or any Lender have been or will be prepared based upon
reasonable assumptions and will constitute CE's and Bidco's good faith estimate
of the items projected. In issuing this commitment and undertaking, CSFB is
relying on the accuracy of the information furnished by CE and Bidco and on
CE's and Bidco's behalf.

                  To induce us to issue this letter, CE and Bidco, jointly and
severally, hereby agree to pay on demand, whether or not any element of the
Transactions is consummated or the Senior Financing is closed or signed, all

counsel retained to represent the Agent and all of the reasonable out-of-pocket

agree to indemnify and hold harmless CSFB, each Lender and each director,

claims, damages, liabilities (or actions or other proceedings commenced or
threatened in respect thereof) or other expenses arise out of or in any way
relate to or result from the Transactions (or any element thereof) or this
letter or the extension of the Senior Financing contemplated by this letter, or
in any way arise from any use or intended use of this letter or the proceeds of
any of the Senior Financing contemplated by this letter, and you agree to
reimburse each indemnified person for any reasonable legal or other expenses
incurred in connection with investigating, defending or participating in any

any such expenses arise), provided that you

                                   agreed upon, without premium or penalty
                                   (except, in the case of Eurodollar Rate
                                   borrowings, prepayments made on the last day
                                   of the relevant interest period).

MANDATORY PREPAYMENTS:             The Term Loan Facility is subject to
                                   mandatory repayment in the amount of
                                   proceeds of asset sales not in the ordinary
                                   course of business, in amounts to be
                                   determined.

                                   Mandatory prepayments of Term Loans may not
                                   be reborrowed.

                                   (C)  The Board of Directors of the Borrower
                                        and NYSEG shall have authorized and
                                        approved the Merger Agreement and the
                                        Lenders shall have received
                                        satisfactory evidence of the same. The
                                        Borrower and NYSEG shall have entered
                                        into the Merger Agreement and the
                                        Merger Agreement shall be in full force
                                        and effect. The terms, conditions and
                                        structure of the Tender Offer and the
                                        Merger, including any amendments
                                        thereto (and the documentation
                                        therefor) shall be in form and
                                        substance reasonably satisfactory to
                                        the Arranger and the Lenders. All
                                        Tendered Shares shall have been
                                        accepted for payment in accordance
                                        with the terms of the Tender Offer. The
                                        Borrower shall, upon consummation of
                                        the Tender Offer, own and control such
                                        number of Shares (on a fully diluted
                                        basis) as shall be necessary to approve
                                        the Merger without the affirmative vote
                                        or approval of any other securityholder
                                        or entity. The Tender Offer and the
                                        financing therefor shall be in
                                        compliance with all laws and
                                        regulations, including any state
                                        anti-takeover law regulating the Tender
                                        Offer or the Merger, or the Arranger
                                        shall have determined such to be
                                        inapplicable to the Tender Offer and
                                        the Merger. The Arranger shall have
                                        received copies, certified by Bidco, of
                                        all filings made with any governmental
                                        authority in connection with the Tender
                                        Offer, the Merger or the other
                                        Transactions.

                                   (D)  Not less than 662/3% of the Shares be
                                        owned by Bidco and/or shall have been
                                        tendered and not withdrawn pursuant to
                                        the Tender Offer and Merger Agreement.

                                   (E)  Either (i) Bidco shall have received
                                        not less than an investment grade
                                        rating with respect to its senior
                                        unsecured debt by both of Standard and

                                        rights at a nominal price, or the
                                        Arranger shall otherwise be satisfied

                                        Merger.

                                   (G)  All material terms and conditions in
                                        the Tender Offer shall have been

                                        except with the consent of the Arranger
                                        and the Lenders, to the satisfaction of
                                        the Arranger and the Lenders.

                                   (H)  All of the net proceeds of the Initial
                                        Equity Contribution shall have been

                                        by the Arranger and the Lenders) that

                  Re:      Commitment Letter

Dear Gentlemen:


                  CalEnergy Company, Inc., a Delaware corporation (the
"Company"), intends to amend and restate the Amended and Restated Credit
Agreement, dated as of July 8, 1996 (as currently in effect, the "Existing
Credit Agreement") among the Company, the banks and other financial
institutions parties thereto, Credit Suisse First Boston ("CSFB") and National
Westminster Bank PLC ("NatWest") as L/C Issuers, NatWest, as Documentation
Agent, CSFB, as Administrative Agent and CSFB and NatWest as Co-Arrangers, as
described herein. You have requested CSFB and Lehman Commercial Paper Inc
("LB") to commit to provide the entirety of such amended and restated facility
which will be in the form of a 3-year revolving loan and standby letter of
credit facility in the amount of U.S. $250 million (such amended and restated
facility, the "Credit Facility"). A summary of the terms and conditions of the
Credit Facility will be the same as those set forth in the Existing Credit
Agreement with only such changes as are set forth in the attached Summary of
Terms and Conditions (the "Term Sheet").

                  We are pleased to confirm that CSFB and LB each hereby
commits (the "Commitments") to provide one-half of the entire Credit Facility
on the terms and conditions set forth herein and in the Term Sheet. Those
matters that are not covered or made clear herein or in the Term Sheet are
subject to mutual agreement of the parties. In addition, the commitment of
CSFB and LB is subject to: (a) the preparation, execution and delivery of
mutually acceptable loan documentation, including a credit agreement
incorporating substantially the terms and conditions outlined herein and in
the Term Sheet; (b) the absence of any material adverse change in the
business, assets, operations, properties, prospects or condition (financial or
otherwise) of the Company and its subsidiaries, taken as a whole, since
December 31, 1996; (c) our not becoming aware after

CalEnergy Company, Inc.

Page 2



the date hereof of any information or other matter which is inconsistent in a
material manner with any information or other matter disclosed to us prior to
the date hereof; (d) prior to December 31, 1997, the absence of any competing
bank credit for, or debt securities of, the Company, being arranged, offered
or placed, other than the facilities described in separate letters among us,
unless the syndication has been completed as agreed among the parties prior to
such date; (e) the Co-Arrangers shall be satisfied with the financial
projections concerning the Company and its subsidiaries which have been or
will be prepared and delivered to the Co-Arrangers in connection with the
Credit Facility and (f) the other conditions set forth in the Term Sheet.

                  In connection with the Credit Facility, CSFB shall act as
sole administrative agent, CSFB and LB shall act as co-arrangers and LB shall
act as documentation agent. You agree that no other entity shall have any
title with respect to the Credit Facility or shall be appointed in the
capacity of agent, co-agent or arranger without the consent of the Company,
CSFB and LB. We reserve the right, prior to or after execution of the
definitive documentation for the Credit Facility, to syndicate all or part of
our commitment to one or more financial institutions or other "accredited
investors" (as defined in Regulation D of the Securities Act of 1933, as
amended) reasonably acceptable to the Company, CSFB and LB (collectively, the
"Lenders" and each a "Lender") that will become parties to such definitive
documentation pursuant to a syndication to be managed and controlled in all
respects by CSFB and LB (including, without limitation, as to the timing of
all offers to potential Lenders and acceptance of commitments, the amounts
offered and the compensation provided to potential Lenders) and that CSFB
would act as the sole and exclusive administrative agent for such Lenders (in
such capacity, the "Agent"). By your acceptance hereof, you agree both before
and after the closing of the Credit Facility to actively assist us in
achieving a syndication that is satisfactory to us, which assistance shall
include but not be limited to: (a) making senior management and
representatives of the Company and its affiliates available to participate in
one or more meetings with potential Lenders at such times and places as CSFB
and LB may reasonably request; (b) using all reasonable efforts to ensure that
the syndication efforts benefit from the Company's and its affiliates'
existing banking relationships; and (c) providing CSFB and LB with information
reasonably deemed necessary to complete the syndication successfully,
including, without limitation, the preparation of such offering materials as
CSFB and LB may reasonably request.

                  The Company hereby represents, warrants and covenants that
(x) all information (other than projections) and data concerning the Company
and its subsidiaries which has been or is hereafter furnished or otherwise
made available to CSFB and LB by the Company or any of its representatives in
connection with the transactions contemplated hereby is and will be complete
and correct in all material respects and does not and will

not contain any untrue statement of a material fact or omit to state a
material fact necessary in order to make the statements contained therein not
misleading in light of the circumstances under which such statements are made
and (y) all financial projections concerning the Company and its subsidiaries
which have been or are hereafter made available to CSFB and LB or any Lender
have been or will be prepared based upon reasonable assumptions and will
constitute the Company's good faith estimate of the items projected. In
issuing this commitment and undertaking, CSFB and LB relying on the accuracy
of the information furnished by the Company and on the Company's behalf.

reasonable costs and expenses (including the reasonable fees and expenses of
Skadden, Arps, Slate, Meagher & Flom LLP as counsel to the Agent, any local
counsel retained to represent the Agent and all of the out-of-pocket expenses
of CSFB, LB and their respective affiliates) incurred by CSFB and LB in
connection with the preparation, execution and delivery of this letter and the
definitive financing agreements for the Credit Facility (and our due diligence
and syndication efforts in connection therewith). In addition, you hereby
agree to pay when and as due the fees described in the Fee Letter referred to
below. You further agree to indemnify and hold harmless CSFB, LB, each Lender
and each director, officer, employee and affiliate thereof (each an
"indemnified person") in connection with any losses, claims, damages,
liabilities or other expenses to which any such indemnified person may become
subject, insofar as such losses, claims, damages, liabilities (or actions or
other proceedings commenced or threatened in respect thereof) or other
expenses arise out of or in any way relate to or result from this letter (or
any element thereof) or the extension of the Credit Facility contemplated by
this letter, or in any way arise from any use or intended use of this letter
or the proceeds of any of the Credit Facility contemplated by this letter, and
you agree to reimburse each indemnified person for any reasonable legal or
other expenses incurred in connection with investigating, defending or
participating in any such loss, claim, damage, liability or action or other
proceeding (whether or not such indemnified person is a party to any action or
proceeding out of which any such expenses arise), provided that you shall have
no obligation hereunder to indemnify any indemnified person for any loss,
claim, damage, liability or expense to the extent it is determined by final
judgment of a court of competent jurisdiction to have resulted from the gross
negligence or willful misconduct of such indemnified person. This letter is
furnished for your benefit, and may not be relied upon by any other person or
entity. Neither CSFB, LB, any Lender nor any of their respective affiliates
shall be responsible or liable to you or any other person for consequential
damages which may be alleged as a result of this letter.

of their respective affiliates in providing the services contemplated by this
letter and to allocate,

such manner as CSFB and LB and their respective affiliates may agree in their
sole discretion. You acknowledge that CSFB and LB may share with any of their
respective affiliates, and such affiliates may share with CSFB and LB, any
information relating to the Company and its respective subsidiaries and
affiliates (including, without limitation, any non-public information
regarding the Company and its subsidiaries and affiliates), subject to CSFB's
and LB's maintaining the confidential treatment of such confidential
information.

shall survive any termination of this letter.

and you are not authorized to show or disclose this letter or the contents
thereof in any public filing or announcement or to any other person or entity
(other than your legal and financial advisors in connection with your

                  Re:      Commitment Letter

Dear Gentlemen:

                  You have advised Credit Suisse First Boston ("CSFB") and
Lehman Commercial Paper Inc. ("LB" and, together with CSFB, sometimes referred
to as "us" or "we"), that senior bank financing is required by the CalEnergy
Company, Inc., a Delaware corporation (the "Company"), and that such financing
will be in the form of a 3-year revolving credit facility in the amount of
U.S. $150 million (the "Credit Facility"). The Credit Facility will be
evidenced by a credit agreement substantially in the form of the Amended and
Restated Credit Agreement, dated as of July 8, 1996 (as currently in effect,
the "Existing Credit Agreement") among the Company, the banks and other
financial institutions parties thereto, CSFB and National Westminster Bank PLC
("NatWest"), as L/C Issuers, NatWest, as Documentation Agent, CSFB, as
Administrative Agent and CSFB and NatWest, as Co-Arrangers. The terms and
conditions of the Credit Facility will be the same as the Existing Credit
Facility with only such changes as are set forth in the attached Summary of
Certain Terms and Conditions (the "Term Sheet").

                  We are pleased to confirm that CSFB and LB each hereby
commits (the "Commitments") to provide one-half of the entire Credit Facility
on the terms and conditions set forth herein and in the Term Sheet. Those
matters that are not covered or made clear herein or in the Term Sheet are
subject to mutual agreement of the parties. In addition, the commitment of
CSFB and LB is subject to: (a) the preparation, execution and delivery of
mutually acceptable loan documentation, including a credit agreement
incorporating substantially the terms and conditions outlined herein and in
the Term Sheet; (b) the absence of any material adverse change in the
business, 


<PAGE>
assets, operations, properties, prospects or condition (financial or
otherwise) of the Company and its subsidiaries, taken as a whole, since
December 31, 1996; (c) our not becoming aware after the date hereof of any
information or other matter which is inconsistent in a material manner with
any information or other matter disclosed to us prior to the date hereof; (d)
prior to December 31, 1997, the absence of any competing bank credit for, or
debt securities of, the Company being arranged, offered or placed, other than
the facilities described in separate letters among us, unless the syndication
has been completed as agreed among CSFB, LB and the Company prior to such
date, (e) the Co-Arrangers shall be satisfied with the financial projections
concerning the Company and its subsidiaries in connection with the Credit
Facility, and (f) the other conditions set forth in the Term Sheet (including,
without limitation, additional conditions precedent which, although not set
forth expressly in the Term Sheet, shall be agreed to among the Company, CSFB,
LB and the Lenders (as hereinafter defined), which additional conditions may,
depending on the facts and circumstances existing at the time such Credit
Facility is to be drawn, be similar to those listed as conditions precedent to
the $250 million revolving credit facility as set forth in that separate
commitment letter, dated as of the date hereof, among the Company, CSFB and LB
(including those set forth in the Term Sheet referred to therein) and/or those
conditions precedent to the $500 million bridge loan facility as set forth in
the commitment letter, dated the date hereof, among the Company, CSFB and LB
relating to such bridge loan facility and/or other mutually agreed
conditions).

                  In connection with the Credit Facility, CSFB shall act as
sole administrative agent, CSFB and LB shall act as co-arrangers and LB shall
act as documentation agent. You agree that no other entity shall have any
title with respect to the Credit Facility, or shall be appointed in the
capacity of agent, co-agent or arranger without the consent of the Company,
CSFB and LB. We reserve the right, prior to or after execution of the
definitive documentation for the Credit Facility, to syndicate all or part of
our commitment to one or more financial institutions or other "accredited
investors" (as defined in Regulation D of the Securities Act) reasonably
acceptable to the Company, CSFB and LB (collectively, the "Lenders" and each a
"Lender") that will become parties to such definitive documentation pursuant
to a syndication to be managed and controlled in all respects by CSFB and LB
(including, without limitation, as to the timing of all offers to potential
Lenders and acceptance of commitments, the amounts offered and the
compensation provided to potential Lenders) and that CSFB would act as the
sole and exclusive administrative agent for such Lenders (in such capacity,
the "Agent"). By your acceptance hereof, you agree both before and after the
closing of the Credit Facility to actively assist us in achieving a
syndica-

tion that is satisfactory to us, which assistance shall include but not be
limited to: (a) making senior management and representatives of the Company
and its affiliates available to participate in one or more meetings with
potential Lenders at such times and places as CSFB and LB may reasonably
request; (b) using all reasonable efforts to ensure that the syndication
efforts benefit from the Company's and its affiliates' existing banking
relationships; and (c) providing CSFB and LB with information reasonably
deemed necessary to complete the syndication successfully, including, without
limitation, the preparation of such offering materials as CSFB and LB may
reasonably request.

                  The Company hereby represents, warrants and covenants that
(x) all information (other than projections) and data concerning the Company
and its subsidiaries which has been or is hereafter furnished or otherwise
made available to CSFB and LB by the Company or any of its representatives in
connection with the transactions contemplated hereby is and will be complete
and correct in all material respects and does not and will not contain any
untrue statement of a material fact or omit to state a material fact necessary
in order to make the statements contained therein not misleading in light of
the circumstances under which such statements are made and (y) all financial
projections concerning the Company and its subsidiaries which have been or are
hereafter made available to CSFB and LB or any Lender have been or will be
prepared based upon reasonable assumptions and will constitute the Company's
and Bidco's good faith estimate of the items projected. In issuing this
commitment and undertaking, CSFB and LB relying on the accuracy of the
information furnished by the Company and Bidco and on the Company's and
Bidco's behalf.

                  To induce us to issue this letter, the Company hereby agrees
to pay on demand, whether or not the Credit Facility is closed or signed, all
reasonable costs and expenses (including the reasonable fees and expenses of
Skadden, Arps, Slate, Meagher & Flom LLP as counsel to the Agent, any local
counsel retained to represent the Agent and all of the out-of-pocket expenses
of CSFB, LB and their respective affiliates) incurred by CSFB and LB in
connection with the preparation, execution and delivery of this letter and the
definitive financing agreements for the Credit Facility (and our due diligence
and syndication efforts in connection therewith). In addition, you hereby
agree to pay when and as due the fees described in the Fee Letter referred to
below. You further agree to indemnify and hold harmless CSFB, LB, each Lender
and each director,

connection with any losses, claims, damages, liabilities or other expenses to
which any such indemnified person may become subject, insofar as such losses,
claims, damages, liabilities (or actions or other proceedings commenced or
threatened in respect thereof) or other expenses arise out of or in any way
relate to or result from this letter (or any element thereof) or the extension
of the Credit Facility contemplated by this letter, or in any way arise from

(including, if no senior unsecured long-term debt securities of Borrower are
outstanding, any such ratings that Moody's or S&P has explicitly stated may be
implied from the ratings it has assigned to Borrower's outstanding
subordinated unsecured long-term debt securities) without third-party credit
enhancement, and any rating assigned to any other debt security of Borrower
shall be disregarded. The rating in effect at any date is that in effect at
the close of business on such date.

                         Bridge Loan Commitment Letter


Ladies and Gentlemen:

                  CalEnergy Company, Inc., a Delaware corporation ("you" or
"CE") have advised Credit Suisse First Boston ("CSFB") and LB I Group Inc.
("LB" and, together with CSFB, sometimes referred to as "we", "us" or the
"Bridge Lenders") that your wholly owned subsidiary, CE Electric (NY), Inc., a
New York corporation ("Bidco"), intends to acquire (the "Acquisition") all of
the issued and outstanding shares (the "Shares") of New York State Electric &
Gas Corporation, a New York corporation ("NYSEG") by means of a takeover bid
(the "Tender Offer") and subsequent merger, as a result of which a subsidiary
of Bidco will be merged with and into NYSEG (the "Merger") pursuant to a merger
agreement with NYSEG (the "Merger Agreement"), and NYSEG will become an
indirect wholly owned subsidiary of CE. The Tender Offer, Acquisition and the
Merger are referred to herein as the "Transactions."

                  You have further advised us that, in connection with the
Transactions, you propose to issue a combination of debt securities (the "Debt
Offering") in a registered public offering, a Rule 144A offering or other
offering exempt from the registration requirements of the Securities Act of
1933, as amended (the "Securities Act"), and common stock, $.0675 par value of
CE ("CE Common Stock") (or securities convertible into or exercisable or ex-



<PAGE>


CalEnergy Company, Inc.

Page 2


changeable for common stock) in a registered public offering or in an offering
exempt from the registration requirements of the Securities Act (the "Equity
Offering" and, together with the Debt Offering, the "Offerings"). To the extent
that the Offerings result in less than $500 million of net proceeds to CE, CE
will require a bridge loan facility of up to $500 million (the "Bridge Loan
Facility").

                  You have requested that the Bridge Lenders commit, subject to
the fulfillment of certain conditions set forth herein, to provide the Bridge
Loan Facility to you in an aggregate amount of up to $500 million, less the
amount of net proceeds, if any, raised in the Offerings (the "Bridge Loan").

                  The intention and the expectation of CE and the Bridge
Lenders is to consummate both the Equity Offering and the Debt Offering
promptly and to borrow the Bridge Loan only to the extent the Offerings fail to
yield net proceeds of at least $500 million.

                  Accordingly, subject to the terms and conditions set forth
below, the Bridge Lenders hereby agree with you as follows:

                  1. Commitment. Each of CSFB and LB severally hereby commit
(the "Commitment") to provide one half of the Bridge Loan on the terms set
forth on the Summary of Principal Terms and Conditions attached as Exhibit A
hereto (the "Term Sheet"), subject to the completion of reasonable and
customary due diligence satisfactory to us and the additional closing
conditions to be set forth in the definitive documentation relating to the
Bridge Loan (the "Bridge Loan Documents"), including without limitation those
conditions set forth in Annex III to the Term Sheet (or, in the event of the
Escrowed Funding referred to below, those conditions set forth in Annex II to
the Term Sheet).

                  2. Bridge Facility. (a) In the event that, within 364 days
after the execution of this letter (such



<PAGE>


CalEnergy Company, Inc.
August 6, 1997
Page 3


364 day period, the "Bridge Loan Availability Period"), the net proceeds
received by CE from the Offerings are less than $500 million in the aggregate
(such deficiency, the "Deficiency Amount"), CE shall have the right (subject to
the conditions contained herein) until the end of the Bridge Loan Availability
Period, to draw down on the Bridge Loan in an amount up to the Deficiency
Amount by giving a notice (the "Borrowing Notice") to CSFB and LB at least 10
days prior to the date of borrowing (which Borrowing Notice shall also set
forth the amount, not to exceed the Deficiency Amount, requested to be
borrowed).

                  (b) If the Bridge Loans are not drawn by the end of the
Bridge Loan Availability Period, then, at the option of the Bridge Lenders in
their sole discretion, the Bridge Lenders may, provided that the Merger
Agreement has been executed and is in full force and effect and will not
terminate by its terms during the Extension Period (as defined below) either
(i) waive the conditions precedent to funding requiring that all conditions to
consummation of the Merger set forth in the Merger Agreement (the "Merger
Agreement Conditions") be satisfied or (ii) extend the Bridge Loan Availability
Period for an additional 30 day period after the end of the initial Bridge Loan
Availability Period (such extended 30 day period, the "Extension Period"). In
the event the Bridge Lenders waive the conditions precedent to funding referred
to in clause (i) above, CE may, subject to satisfaction of the conditions
precedent set forth in Annex II to the Term Sheet, borrow the Bridge Loans,
provided that the proceeds thereof are deposited with an escrow agent (the
"Escrow Agent") selected by CSFB and LB to be held by the Escrow Agent in
escrow (the "Escrowed Proceeds"; the funding of the Bridge Loan made pursuant
to this paragraph (b) referred to as the "Escrowed Funding"), to be released
only upon satisfaction of the conditions precedent set forth in Annex III to
the Term Sheet. In the event that (x) the Merger is not consummated within 365
days of an Escrowed Funding or (y) if the Merger Agreement is terminated or
ceases to be in full force and effect, whichever is sooner, the Escrowed
Proceeds shall

be released to CSFB and LB to be applied to the mandatory
repayment of the outstanding Bridge Loans.

                  3. Obligations of CE. You agree to fully cooperate with the
Bridge Lenders and to provide the Bridge Lenders with all information required
by the Bridge Lenders in connection with the Offerings. CE shall, without
limitation and in addition to all of its other obligations herein:

                           (a)      in order to facilitate the Offerings,
prepare and file with the SEC as expeditiously as possible but in no event
later than 30 days after the date of this letter a "universal" or "generic"
shelf registration statement on Form S-3 (the "Registration Statement")
relating to the issuance and sale by CE of debt securities, CE Common Stock,
preferred stock or any other equity securities or securities that are
exchangeable or exer-cisable for or convertible into CE Common Stock on a
delayed or continuous basis pursuant to Rule 415 (or any successor rule to
similar effect) promulgated under the Securities Act.

                           (b) use its best efforts to cause the
Registration Statement to become effective as soon as
practicable;

                           (c)      prepare and file with the SEC such
amendments and supplements to the Registration Statement and the prospectus
used in connection therewith as may be necessary to effectuate the Offerings
contemplated thereby, including filing any and all necessary periodic reports
on a timely basis (including Forms 8-K relating to the Transactions);

                           (d)      before filing the Registration State-
ment or prospectus or any amendments or supplements thereto, other than any
documents incorporated by reference therein, CE shall (i) promptly furnish to
the Bridge Lenders copies of all such documents proposed to be filed, which
documents shall be subject to the review by the Bridge Lenders, and (ii) notify
the Bridge Lenders of

any stop order issued or threatened by the SEC and take all reasonable actions
required to prevent the entry of such stop order or to remove it if entered;

                           (e) in the event the Bridge Lenders advise
CE to consummate either of the Offerings in a transaction exempt from
registration under the Securities Act, CE will comply with the applicable
provisions of this Section 3 and will (i) promptly prepare an offering
memorandum, containing such disclosures as may be required by the Securities
Act and other applicable laws and other disclosures as are customary and
appropriate for such a document, in form and substance reasonably satisfactory
to the Bridge Lenders, and (ii) execute, in customary form, a purchase
agreement and registration rights agreement, in form and substance reasonably
satisfactory to the Bridge Lenders and perform its obligations thereunder;

                           (f)      promptly issue securities in the
Offerings at such prices and with such terms, including interest rates,
dividend rates and conversion rates, as the Bridge Lenders consider appropriate
(after consultation with you) in light of market conditions at the time of
sale;

                           (g)      make available for inspection by the
Bridge Lenders, any underwriter participating in any distribution pursuant to
the Registration Statement, and any attorney, accountant or other agent
retained by such persons (collectively, the "Inspectors"), all financial and
other records, pertinent corporate documents and properties (collectively,
"Information") of CE, NYSEG and their respective subsidiaries, as shall be
reasonably necessary to enable them to conduct a customary due diligence
investigation, and cause its and its subsidiaries' officers, directors and
employees to supply all information and respond to all inquiries reasonably
requested by any such Inspector in connection with such due diligence
investigation, provided that, with respect to the requirements set forth in
this subsection (g) as it relates to NYSEG and its subsidiaries, such
obligation



<PAGE>


CalEnergy Company, Inc.

Page 6


shall, to the extent such Information is not otherwise in CE's possession or
within CE's control, be to use CE's best efforts to make such Information of
NYSEG and its Subsidiaries so available;

                           (h)      make available senior management per-
sonnel to participate in, and cause them to cooperate with the underwriters,
initial purchasers or placement agents in connection with, "road show" and
other customary marketing activities, including "one-on-one" meetings with
prospective purchasers of the securities to be sold in the Offerings to the
same extent as if CE was engaged in a primary registered offering of CE Common
Stock;

                           (i) in connection with a registered public
Offering, execute underwriting agreements in customary form reasonably
satisfactory in form and substance to the Bridge Lenders and perform its
obligations thereunder;

                           (j) deliver to the Bridge Lenders legal
opinions in form and substance reasonably satisfactory to
the Bridge Lenders;

                           (k) cause its certified public accountants
to deliver to the Bridge Lenders "comfort letters" in
customary form and substance; and

                           (l)      otherwise cooperate with the Bridge
Lenders in connection with the Offerings.

                  Certain additional matters with respect to the Offerings are
governed by the Engagement Letter (as defined below).

         4. Syndication Rights. Each of CSFB and LB reserves the right to and
may, prior to or after the execution of the Bridge Loan Documents, to syndicate
all or a portion of its Commitment to one or more financial institutions (such
financial institutions, together with CSFB and LB, the "Lenders") reasonably
satisfactory to you, CSFB and LB that will become parties to the Bridge Loan



<PAGE>


CalEnergy Company, Inc.

Page 7


Documents. It is agreed that CSFB will act as agent and syndication coordinator
of the Bridge Loan, and LB will act as documentation agent of the Bridge Loan.
No additional agents or co-agents will be appointed without the prior written
consent of CSFB and LB. Completion of the syndication of the Bridge Loan is not
a condition to CSFB's or LB's funding the Bridge Loan.

                  You agree to assist CSFB and LB in forming any such syndicate
and to provide the Lenders, promptly upon request of CSFB and LB, with all
information reasonably requested by CSFB and LB to complete successfully the
syndication, including but not limited to (a) an information package for
delivery to potential Lenders and participants and (b) all information and
projections prepared by you or your advisers relating to the transactions
described herein. You also agree to use your best efforts to ensure that CSFB's
and LB's syndication efforts benefit from your existing lending relationships.
You further agree to make your senior officers and representatives, and those
of Bidco, available to participate in informational meetings for potential
Lenders and participants at such times and places as CSFB and LB may reasonably
request. In connection with the syndication of the Bridge Loan, CSFB and LB
may, in their discretion, allocate to other Lenders portions of any fees
payable to CSFB and LB in connection with the Bridge Loan. You agree that no
Lender will receive any compensation of any kind for its participation in the
Bridge Loan except as expressly provided for in this letter or in the Fee
Letter referred to below.

                  5. Representations and Warranties. You represent and warrant
and covenant that:

                  (a) all information (other than projections) which has been
         or is hereafter furnished to CSFB or LB by you or any of your
         representatives in connection with the Transactions and the Offerings
         is and will be complete and correct in all material respects as of the
         time furnished and does not and will not as of the time furnished
         contain any untrue



<PAGE>


CalEnergy Company, Inc.

Page 8


         statement of a material fact or omit to state a material fact
         necessary in order to make the statements contained therein not
         misleading in light of the circumstances under which such statements
         were made; and

                  (b) all financial projections that have been or are hereafter
         prepared by you or on your behalf and made available to CSFB and LB
         have been or will be prepared in good faith based upon reasonable
         assumptions.

                  You agree to supplement the information and projections
referred to in clauses (a) and (b) above from time to time until completion of
the syndication so that the representations and warranties in the preceding
sentence remain correct without regard to when such information and projections
were furnished. All information with respect to NYSEG referred to in clause (a)
above shall, prior to the initial funding of the Bridge Loan, be given to the
best knowledge of CE and all information with respect to NYSEG which is
hereafter furnished by CE or any of its representatives shall be deemed to
supplement the information previously given by CE or its representatives to the
extent it relates to NYSEG. In arranging and syndicating the Bridge Loan, CSFB
and LB will be entitled to use and rely on such information and projections
without independent verification thereof.

                  6. Fees and Expenses. You agree to reimburse CSFB, LB and
their affiliates, upon request, for their reasonable fees and expenses incurred
in connection with the preparation, execution and delivery of this letter, the
Term Sheet and the Bridge Loan Documents and the activities thereunder or
contemplated thereby, including syndication expenses (other than fees allocated
in accordance with Section 4 hereof) including, without limitation, the
reimbursement of CSFB, LB and their respective affiliates, upon request, for
the reasonable fees and expenses of their counsel (including the fees and
expenses of Skadden, Arps, Slate, Meagher & Flom LLP), whether or not the
Transactions, the Offerings or the Bridge

be disclosed by you to any person other than (i) accountants, attorneys and
advisors for you or any of your affiliates, (ii) rating agencies, (iii) to the
extent approved by CSFB and LB, other advisors in connection with the
Transactions, and then only on a confidential basis, and (iv) as required by

supplemented as set forth in a separate fee letter (the "Fee Letter") and

Engagement Letter. By executing this letter, you acknowledge that this letter,
the Term Sheet and the Fee Letter are the only agreements between you and the
Bridge Lenders (or any of their affiliates) with respect to the Bridge Loan and
set forth the entire understanding of the parties with respect thereto. None of

reference herein and constitute a part hereof, shall apply to actions hereunder

unless (i) the Bridge Lenders and CE have extended the term hereof in writing,
or (ii) the Bridge Lenders extended the term hereof pursuant to Section 2
hereof; provided, however, that the Commitment shall also terminate if (i) you
have not accepted this letter by 5:00 p.m. (New York time) on August 6, 1997,
or (ii) the acquisition proposal by CE (or any of its affiliates) is terminated
or abandoned, or the Merger Agreement, in the event it is entered into, is
terminated or ceases to be effective. No termination shall affect the
obligations set forth in Sections 6, 7, 8 and 9, which shall survive any such

Interest Rates:                             Prior to the Bridge Maturity
                                            Date, the Bridge Loans will
                                            accrue interest at a rate per
                                            annum equal to 3 month Adjusted

                                            The "Applicable Spread" on the
                                            Bridge Loans will initially be 600
                                            basis points and will increase by
                                            100 basis points at the end of the
                                            six month period following the
                                            Closing Date and by an additional
                                            50 basis points at the end of each
                                            three-month period thereafter until
                                            the Bridge Maturity Date; provided,

                                            Bridge Loans in effect at any time
                                            prior to the Bridge Maturity Date
                                            shall not exceed 17% per annum; to
                                            the extent that the interest

                                            a rate of 15% per annum, Borrower
                                            may, at its option, cause such
                                            excess interest to be paid in the
                                            form of additional bridge notes.

                                            Adjusted LIBOR will at all times
                                            include any applicable statutory
                                            reserves.

                                            In the event that Adjusted LIBOR
                                            cannot be determined, or any Lender

                                            will accrue interest until the

                                            Following the Bridge Maturity Date,
                                            all outstanding Bridge Loans will

         in connection with the Transactions will not exceed an amount to be
         agreed upon between the Borrower, CSFB and LB.

                  (x) Each of the Transactions shall have been consummated in
         all material respects in accordance with the terms hereof and the
         terms of documentation therefor (without the waiver of any material
         condition unless consented to by CSFB and LB and the Lenders) that are
         in form and substance reasonably satisfactory to CSFB, LB and the
         Lenders.

                  (xi) All requisite third parties and governmental authorities
         shall have approved or consented to the Transactions and the other
         transactions contemplated hereby (without the imposition of any
         materially burdensome or adverse conditions) and all such approvals
         and consents shall be in full force and effect (or there shall be a
         plan reasonably satisfactory to the CSFB and LB for the obtaining
         thereof), including, without limitation, the approval of the New York
         Public Service Commission (the "New York PSC"), the Nuclear Regulatory
         Commission (the "NRC") and the Federal Energy Regulatory Commission
         ("FERC"). All applicable waiting periods shall have expired without
         any action being taken by any competent authority which restrains,
         prevents, or imposes materially adverse conditions upon the
         Transactions.

                  (xii) CSFB, LB and the Lenders shall be satisfied (in their
         reasonable judgment) with the proposed and actual capitalization and
         corporate and organizational structure of Borrower, Bidco, NYSEG and
         their respective subsidiaries (after giving effect to the
         Transactions), including as to direct and indirect ownership and as to
         the terms of the indebtedness and capital stock of Bidco, NYSEG and
         their respective subsidiaries.

                  (xiii) All conditions precedent under all documentation
         relating to the Transactions or the financing or refinancing thereof
         as the case may be shall have been satisfied (except to the extent
         such conditions have been waived with the prior consent of CSFB, LB
         and the Lenders).
