"Management  Services  Agreement"),  a power  supply  agreement  in the  form of
Exhibit B attached hereto (the "Power Supply  Agreement"),  an energy management

purchase  right  agreement  in the  form  of  Exhibit  D  attached  hereto  (the
"Generation  Purchase Right Agreement") and a guaranty  agreement in the form of
Exhibit E attached  hereto (the  "Guaranty  Agreement")  and/or (ii) receive the
assets and  properties  of Company set forth on Schedule A attached  hereto (the
"Transferred  Assets").  Parent,  upon written notice to the parties hereto, may
direct any portion of the  Transferred  Assets to be distributed to a particular
Transferee Subsidiary;  provided,  however, that the Transferee Subsidiary which
is designated  by Parent to receive the assets  contemplated  by the  Generation
Purchase Right Agreement to be subject to Company's  rights  thereunder shall be
the  Transferee  Subsidiary  that  enters  into the  Generation  Purchase  Right
Agreement.

               (b) Company shall,  reasonably  prior to the anticipated  Closing
Date,  form a new New York  corporation  to act as Parent  hereunder and to own,
directly  or  indirectly,  all of the  stock or other  equity  interests  of the
Transferee  Subsidiaries,  shall  provide  Authority  and LIPA Sub with  written
notice of such  formation  and shall cause such new  corporation  to execute and
deliver a counterpart hereof, whereupon such new corporation shall become Parent

wholly-owned subsidiary of Company its ownership interest in the Nine Mile Point
Two Nuclear Power Plant and its interest in all related nuclear fuel and nuclear
decommissioning  trust funds ("Nine Mile"),  but Company's failure to obtain any
required  consent  thereto  of any  governmental  agency  or other  owner of any
interest therein shall not constitute a breach of this Agreement.

               (d)(i)  Immediately  prior to the Effective  Time,  Company shall
transfer the Transferred Assets to the Transferee  Subsidiaries in exchange for,
and Parent shall deliver to Company,  (i) the Designated  Number (as hereinafter

preferred  stock in an aggregate  face amount and having the rights and terms to
be specified in a notice delivered by Parent to each party hereto not later than
the date on which the notices of redemption are issued  pursuant to Section 1.11
(the "New Parent Preferred Stock").  The "Designated Number" shall be the number
of shares of Parent  Common Stock  specified in a notice  delivered by Parent to
each party  hereto not later than the date on which such  notices of  redemption
are  issued  pursuant  to  Section  1.11 and  representing  Parent's  good faith
estimate of the net fair market  value of the  Transferred  Assets less the face
amount of New  Parent  Preferred  Stock  delivered  by Parent  pursuant  to this
Section 1.4(d).  Concurrently  with such delivery and  immediately  prior to the
Effective Time, Company shall sell for cash in a private placement all shares of
New Parent Preferred

Stock to one or more persons or entities which are not otherwise shareholders of
Company or BU at the Effective Time.

BUGLILCO Transactions (as defined in Section 2.1(b)) have been consummated prior
to the Effective Time, the transfer of the Transferred Assets as contemplated by
such  clause  (i) shall be made  without  the  delivery  by Parent of any Parent
Common Stock or New Parent Preferred Stock.

               Section 1.5 Description of Assets.  To the extent that Schedule A
hereto  (the  "Transferred  Asset  Schedule")  does not provide for a full legal

shall revise the  Transferred  Asset Schedule prior to the Closing in accordance
with the principles and procedures set forth on Schedule B attached hereto.

               Section 1.6 Liabilities.

               (a) At the Closing,  Parent and each  Transferee  Subsidiary will

respective  actions  set forth on  Schedule C attached  hereto to prepare for an
orderly transition under the Basic Agreements at the Effective Time.

anticipated Closing Date, Authority shall cause LIPA Sub to be duly incorporated
as a New York  corporation  and shall cause LIPA Sub to execute a counterpart of
this  Agreement.  Each  representation  and warranty set forth in Article V with
respect  to LIPA  Sub  shall be  deemed  to have  been  made on the date of such
execution.

               Section 1.10 Charter Amendment. Authority shall cause the Amended
and  Restated   Certificate  of  Incorporation  of  Company  to  be  amended  as
contemplated in the request for a ruling from the Internal  Revenue Service with
respect to Section 115 of

the Internal  Revenue Code of 1986, as amended (the "Code"),  not later than the
tenth business day after the Effective Time.

               Section 1.11 Certain Other  Preferred  Stock.  Promptly after all
conditions  to the  Closing  set forth in Article  VIII have been  satisfied  or
waived in accordance therewith (other than Section 8.1(b),  provided Company has
received  assurances   satisfactory  to  Company  that  such  condition  can  be
satisfied), Company shall issue notices of redemption for all outstanding shares
of Company Preferred Stock (as defined in Section 4.3) (other than the Series AA
Preferred Stock and the other series thereof specifically referred to in Section
2.1(c)(iii))  and shall pay all  amounts  due in respect of such  redemption  as
promptly as  practicable in accordance  with the  applicable  terms of Company's
Amended and Restated Certificate of Incorporation.

                           TREATMENT OF SHARES

               Section  2.1  Effect  of the  Merger  on  Capital  Stock.  At the
Effective  Time,  by virtue of the Merger and  without any action on the part of
any holder of any capital stock of Parent, Company or LIPA Sub:

               (a)  Cancellation  of  Certain  Stock.  (i) Each share of Company
Common Stock and each share of Company  Preferred Stock that is owned by Company
as treasury stock, and each share of Company Preferred Stock owned by any direct
or  indirect  wholly  owned  Subsidiary  (as  defined in Section  4.1) of Parent
immediately  prior to the  Effective  Time  shall,  by virtue of the  Merger and
without any action on the part of the holder  thereof,  cease to be outstanding,
be cancelled and retired without payment of any consideration therefor and cease
to exist.

               (ii) Each share of the common stock of LIPA Sub, by virtue of the
Merger  and  without  any  action on the part of the  holder  thereof,  shall be
cancelled and converted into the right to receive one fully paid and, subject to
Section 630 of the NYBCL,  non-assessable share of common stock of the Surviving
Corporation.

               (b)  Treatment  of  Company  Common  Stock.  (i) Each  issued and
outstanding share of Company Common Stock,  other than shares cancelled pursuant

shall be cancelled and converted into the right to receive (x) an amount of cash
equal to the Cash Purchase  Price (as defined in Section  2.1(d)(i))  divided by
the number of shares of Company  Common  Stock  outstanding  on the Closing Date
(the  "Common  Stock  Conversion  Amount")  and (y) a number of shares of Parent
Common Stock (the  "Transferred  Assets Stock  Portion")  equal to the number of
shares of Parent  Common  Stock  received  by Company  pursuant to clause (i) of
Section  1.4(d)  divided  by the  number  of  shares  of  Company  Common  Stock
outstanding on the Closing Date.

Each holder of any such share of Company  Common Stock shall be deemed hereby to
have appointed the Exchange Agent (as defined in Section 2.3(a)) as its agent to
subscribe  for shares of Parent  Common Stock by applying the  aggregate  Common
Stock Conversion Amount for such purchase. The number of shares of Parent Common
Stock to be purchased for the Common Stock Conversion  Amount shall be (x) 0.880
shares of Parent Common Stock less the  Transferred  Assets Stock Portion if the
transactions   contemplated   by   the   Exchange   Agreement   (the   "BUGLILCO
Transactions")  will be  consummated  contemporaneously  with  the  transactions
contemplated hereby or (y) one share of Parent Common Stock less the Transferred
Assets  Stock  Portion  if the  BUGLILCO  Transactions  will not be  consummated
contemporaneously   with  the  transactions   contemplated   hereby.  Upon  such
cancellation,  all such shares of Company Common Stock shall cease to exist, and
each holder of a certificate  formerly  representing any such shares shall cease
to have any rights  with  respect  thereto,  except the right to receive  Parent
Common Stock  purchased  pursuant to the second  sentence of this Section 2.1(b)
and  distributed  pursuant to clause (y) of the first  sentence of this  Section
2.1(b).

               (ii)  Notwithstanding  clause (i) of this Section 2.1(b),  if the
BUGLILCO  Transactions  have been consummated  prior to the Effective Time, each
issued and  outstanding  share of Company  Common Stock shall be  cancelled  and
converted  into the right to receive  only an amount of cash equal to the Common
Stock  Conversion  Amount and the  transactions  contemplated  by the second and
third sentences of such clause (i) shall not occur.

               (c)  Treatment of Company  Preferred  Stock.  (i) Each issued and
outstanding  share of Series AA  Preferred  Stock  other than  shares  cancelled
pursuant to Section 2.1(a) and Company  Dissenting Shares shall be cancelled and
converted  into the right to receive one fully paid and,  subject to Section 630
of the NYBCL,  non-assessable share of preferred stock, par value $25 per share,
of Parent ("Parent  Preferred Stock") with identical rights (including  dividend
rates) and  designations  to the Series AA  Preferred  Stock as set forth in the
Certificate of Designation  attached hereto as Exhibit H. Upon such  conversion,
each  holder of a  certificate  formerly  representing  any  shares of Series AA
Preferred Stock shall cease to have any rights with respect thereto,  except the
right to receive the shares of Parent Preferred Stock in consideration  therefor
upon the surrender of such certificate in accordance with Section 2.3.

               (ii) Each issued and outstanding share of Company Preferred Stock
that is subject to optional  redemption by Company at or before the Closing Date
(other  than  shares  cancelled   pursuant  to  Section  2.1(a)   (collectively,
"Redeemable  Preferred  Stock")  shall be called  for  redemption  by Company as
provided  in Section  1.11 and all such  shares  shall be  redeemed  for cash by
Company in accordance  with the terms  applicable to such shares.  The aggregate
amount of accrued  but  unpaid  dividends  and  redemption  premiums  payable by
Company in respect of such


                                       -6-


<PAGE>

redemptions  (the  "Aggregate  Redemption  Premium")  shall be paid by Parent to
Company  not  later  than two  business  days  prior to the date the  applicable
redemption price is payable.

               (iii) Each  issued  and  outstanding  share of Company  Preferred
Stock  (other  than  shares  cancelled  pursuant  to  Section  2.1(a),   Company
Dissenting Shares,  shares of Series AA Preferred Stock and Redeemable Preferred
Stock) (collectively,  "Non- redeemable Preferred Stock") shall be cancelled and
converted  into the right to  receive  cash in the  amount of the sum of (x) the
Make-Whole Amount (as hereinafter  defined) and (y) accrued but unpaid dividends
in respect of such share through the Closing  Date. As used herein,  "Make-Whole
Amount" with  respect to each share of  Nonredeemable  Preferred  Stock means an
amount  equal to the  present  value of (A) the face or  liquidation  preference
amount,  whichever is applicable,  of such share and (B) the remaining  dividend
payments due on such share  between the Closing  Date and the  earliest  date on
which Company may redeem such share, computed using a discount rate equal to the
applicable  Fair Market Rate  divided by 0.95.  "Fair Market Rate" is defined as
the Generic General Obligation Fair Market Yield for Baa rated Low/Medium Coupon
General  Municipal  Obligations  at the time of the  computation  as reported on
Bloomberg,  with a maturity most nearly equal to the period between cancellation
and final  redemption  of such series of  Non-redeemable  Preferred  Stock.  The
period  between  cancellation  and  redemption  refers to the period between the
Closing  Date and:  (A) August 1, 2002,  with respect to the Series CC Preferred
Stock, (B) March 1, 1999, with respect to the Series GG Preferred Stock, (C) May
1, 2001,  with  respect to the Series QQ  Preferred  Stock,  and (D) October 16,
2018,  with  respect to the Series UU Preferred  Stock.  The amount by which the
aggregate  amount payable pursuant to this Section  2.1(c)(iii)  exceeds 100% of
the aggregate face or liquidation  preference amounts,  whichever is applicable,
for all shares of  Nonredeemable  Preferred Stock shall be paid by Parent to the
Surviving Corporation at the Effective Time.

               (d) Cash  Purchase  Price;  Adjustment.  (i) The  "Cash  Purchase
Price" to be paid by Authority shall be $2,497,500,000.

               (ii) The Cash Purchase Price has been  determined  based upon the
net book  value of the  Retained  Assets  (as  defined  in  Section  4.4(b))  of
$2,500,800,000  as set  forth in the pro  forma  consolidated  balance  sheet of
Company as of December  31, 1997  prepared  by Company  (the "Pro Forma  Balance
Sheet").  The Cash Purchase  Price is based upon the  assumption  that the total
long-term  indebtedness  of  Company  on  the  Closing  Date  shall  not  exceed
$3,576,000,000  (the "Retained Debt Amount").  The Retained Debt Amount shall be
adjusted in accordance  with the  adjustment  referred to in Section  2.1(d)(vi)
(the "Adjustment").

               (iii) No later than 60 days after the Closing Date,  Parent shall
prepare  and  deliver  to  Authority,  with a copy  to  Authority's  independent
accountants, Price Waterhouse LLP ("Price


                                       -7-


<PAGE>

Waterhouse"),  the  audited  consolidated  balance  sheet of  Company  as of the
Closing  Date (the  "Closing  Date Balance  Sheet") and a  statement,  as of the
Closing Date (the  "Statement"),  setting forth the amount of the Adjustment and
the  calculations  thereof in  reasonable  detail and  showing  the  differences
between  each  account  contained  in  the  Pro  Forma  Balance  Sheet  and  the
corresponding  account in the Closing  Date  Balance  Sheet.  The  Closing  Date
Balance Sheet and the Statement  shall be prepared in accordance  with generally
accepted  accounting  principles  used  by  Company  in the  preparation  of its
financial  statements  for the year ended  December  31,  1996  ("GAAP"),  using
allocation  procedures consistent with the procedures used by Company to prepare
the Pro Forma Balance  Sheet and its audited  historical  financial  statements.
During the period required to prepare the Closing Date Balance Sheet,  Surviving
Corporation  will make available the books and records of Surviving  Corporation
to Parent, its authorized  representatives  and Parent's  independent  auditors,
Ernst & Young ("E&Y").

               (iv) During the 60-day period  following  receipt by Authority of
the Closing Date Balance Sheet and the  Statement,  Parent shall make  available
and shall direct E&Y to make available to Authority and Price Waterhouse  copies
of the working papers,  books and records used in the preparation of the Closing
Date Balance Sheet and the Statement, as reasonably requested by Authority.  The
Closing Date Balance Sheet and the Statement shall become final and binding upon
the parties at the close of  business  on the  sixtieth  day  following  receipt
thereof by Authority,  except to the extent that Authority  gives written notice
of its  disagreement  with the  Closing  Date  Balance  Sheet  or the  Statement
("Notice of Disagreement") to Parent prior to such date, or if such day is not a
business day, the next following  business day. Any Notice of Disagreement shall
specify in reasonable detail the nature of any disagreement so asserted.

               (v) During the 30-day  period  following the delivery of a Notice
of  Disagreement,  Parent and  Authority  shall seek in good faith to resolve in
writing  any  differences  which  they  may have  with  respect  to the  matters
specified  in the Notice of  Disagreement.  During such  period,  Parent and E&Y
shall  have  access  to the  working  papers  of Price  Waterhouse  prepared  in
connection  with  their  analysis  of any  matter  specified  in the  Notice  of
Disagreement,  as  reasonably  requested  by  Parent,  and  Authority  and Price
Waterhouse shall have access to the working papers of E&Y prepared in connection
with the Closing Date Balance Sheet and the Statement,  as reasonably  requested
by  Authority.  At the end of such 30-day  period,  Parent and  Authority  shall
submit to an independent  accounting firm (the "Accounting Firm") for review and
resolution  of any and all  matters  which  remain in  dispute  and  which  were
included in the Notice of  Disagreement.  The Accounting Firm shall be KPMG Peat
Marwick or, if such firm is unable or  unwilling to act,  such other  nationally
recognized  independent public accounting firm as shall be agreed upon by Parent
and Authority in writing. If


                                       -8-


<PAGE>

Parent and  Authority do not agree on the  selection of a nationally  recognized
independent  accounting  firm,  Price  Waterhouse  and E&Y shall  select a third
accounting  firm to act as the  Accounting  Firm  hereunder.  The  Adjustment as
determined  by  Parent,  as  modified  (if at all) by  resolution  of Parent and
Authority  or by the  Accounting  Firm,  is  referred  to herein  as the  "Final
Adjustment."  The  determination of the Accounting Firm as to such matters shall
be final and binding on the parties hereto,  and Parent and Authority agree that
judgment may be entered upon the  determination  of the  Accounting  Firm in any
court having  jurisdiction over the party against which such determination is to
be enforced.  The fees and expenses of the Accounting Firm incurred  pursuant to
this  Section  2.1(d)(v)  shall be borne by  Parent  and  Authority  in  inverse
proportion as they may prevail on matters resolved by the Accounting Firm, which
proportionate allocations shall also be determined by the Accounting Firm at the
time the  determination  of the Accounting Firm is rendered on the merits of the
matters submitted. The fees and disbursements of E&Y incurred in connection with
their  certification  of the Closing Date Balance  Sheet and the  Statement  and
review of any Notice of  Disagreement  shall be borne by Parent and the fees and
disbursements  of Price  Waterhouse  incurred in connection with their review of
the Closing Date Balance  Sheet,  and the Statement  shall be borne by Surviving
Corporation or Authority.

               (vi) The  Retained  Debt  Amount  shall be (A)  increased  by the
amount,  if any,  by which the net book  value of the  Retained  Assets  exceeds
$2,500,800,000  or (B)  decreased  by the amount,  if any, by which the net book
value of the Retained Assets is less than $2,500,800,000.

               (vii)  The  Transferred  Assets  shall  include  all cash held by
Company at the  Closing  except for the net  proceeds  of the sale of New Parent
Preferred Stock. The accounts payable retained by Company immediately  following
the Closing shall be $101.7 million plus or minus the New Parent Preferred Stock
Adjustment  as  hereinafter  defined.  To the extent that the amount of such net
proceeds from the sale of the New Parent  Preferred Stock is more (the "Excess")
or less than $75 million (the  "Shortfall") the accounts payable retained by the
Company immediately following the Closing shall be increased or decreased by the
amount of the Excess or  Shortfall,  respectively,  (the "New  Parent  Preferred
Stock Agreement").

               (e)  Retained  Debt.  At the Closing,  Parent  shall  execute and
deliver and shall cause each  Transferee  Subsidiary to execute and deliver,  to
Company such promissory notes as shall have an aggregate  principal amount equal
to the excess,  if any, of (i) the  indebtedness  of Company  outstanding on the
Closing Date (the "Closing Date Debt Amount") over (ii) the Retained Debt Amount
and as shall  have such rates and  maturities  (including,  without  limitation,
accelerated  maturities  resulting  from  default and  voluntary  and  mandatory
prepayments)  as  shall  correspond,  to each  portion  of debt  underlying  the
indebtedness of Company on


                                       -9-


<PAGE>

the Closing Date (the "Promissory Notes"); provided, however, that such interest
and principal  payment dates shall be adjusted to require payment by Parent,  30
days prior to the  corresponding  payment  dates on the  underlying  debt, of an
amount which,  including  amounts  assured to be earned by Authority  while such
funds are held by it, will be sufficient to make the corresponding payments. The
aggregate  excess principal amount shall be allocated to each Promissory Note on
a pro rata  basis  such  that  the  ratio of (x) the  principal  amount  of each
Promissory Note to (y) the aggregate excess principal amount shall correspond to
the ratio of (A) the principal amount of the corresponding underlying portion of
debt to (B) the Closing  Date Debt Amount.  The Closing Date Debt Amount  shall,
for the purpose of calculating the aggregate principal amount of such Promissory
Notes,  be the amount set forth in a certificate  signed by the Chief  Financial
Officer of Company and  delivered to Parent and  Authority on the Closing  Date.
Such amount shall be reviewed by E&Y in accordance with Section  2.1(d)(iii) and
the actual amount thereof shall be set forth in the Statement. The actual amount
shall  be  subject  to  review  by  Price  Waterhouse,  in  accordance  with the
procedures  set  forth  in  Section  2.1(d)(iv),  with any  disagreements  being
resolved in accordance with the procedures set forth in Section 2.1(d)(v).  Upon
the final  determination of such amount,  the Promissory Notes shall be adjusted
on a pro rata basis to reflect the principal amount so determined.

               (f) Credit Rating.  (i) If, at any time when any Promissory Notes
are  outstanding,  a Material  Decline in Parent's  Credit  Standing (as defined
below) occurs,  then within 10 days after such occurrence,  Parent shall provide
credit  enhancement  of the  Promissory  Notes  hereunder  at its sole  cost and
expense  in the  form of a  letter  of  credit  securing  the  Promissory  Notes
hereunder in a face amount equal to the  aggregate  outstanding  balances of the
Promissory Notes, issued by a financial  institution whose long-term senior debt
is or would be rated "A", or better by at least two nationally recognized rating
services.

               (ii)  For  purposes  of this  Section,  a  "Material  Decline  in
Parent's  Credit  Standing"  shall be deemed to have  occurred if (1) Parent has
long-term  senior debt  outstanding  which is rated by a  nationally  recognized
rating service and Parent's  long-term  senior debt  outstanding is not rated at
least "A" by two or more such  rating  services,  or (2) in the sole  reasonable
opinion of the  Authority,  in the event  that  Parent  does not have  long-term
senior  debt  outstanding  or such debt is not rated by at least two  nationally
recognized rating services, or the credit standing of Parent declines to a level
which is  insufficient  to support at least an "A" credit  rating by two or more
nationally  recognized  rating  services,  whether  or  not  any  such  debt  is
outstanding.  Parent  shall  immediately  notify the  Authority  of any Material
Decline in Parent's Credit Standing.

               (iii)  Upon the  occurrence  of a Material  Decline  in  Parent's
Credit Standing, Parent shall have the right to


                                      -10-


<PAGE>

economically  defease the  Promissory  Notes by  delivering  to  Authority  U.S.
treasury securities of such maturities and in such principal amounts as shall be
sufficient,  as reasonably determined by Authority, to produce cash at the times
and  in  the  amounts  required  to  pay  all  amounts  due  in  respect  of the
indebtedness underlying the Promissory Notes.

               (g) Treatment of Debt at Closing. (i) The parties shall cooperate
with each other to effect  refinancings,  repayments,  amendments  of  Company's
outstanding  indebtedness and other related  transactions  with the intention of
minimizing the aggregate principal amount of the Promissory Notes and maximizing
the amount of Company's tax-exempt indebtedness at the Effective Time.

               (ii) No party shall be required by this Section  2.1(g) to effect
any transaction that it reasonably determines to be financially adverse to it by
comparison to the transactions contemplated by Section 2.1(e).

               (h) Assumption of Certain Debt. Subject to obtaining all required
consents,  Parent will assume at Closing  (i) the 7.3%  Debentures  due July 15,
1999, with an approximate  aggregate  principal amount currently  outstanding of
$397  million  and (ii)  the  8.20%  Debentures  due  March  15,  2023,  with an
approximate  aggregate  principal amount currently  outstanding of $270 million.
Certain  other tax exempt  authority  financing  notes will be identified by the
parties and assumed by Parent (subject to obtaining all required consents and to
the parties' tax counsel's concurrence).

               (i) Accounts  Receivable and Accrued  Unbilled  Revenues.  Parent
will be  entitled  to/responsible  for any  over/undercollec-  tion in excess of
$500,000 of the  retained  customer  accounts  receivable  and accrued  unbilled
revenues on the Closing  Date  Balance  Sheet.  Prior to the Closing  Date,  the

               Section 2.2 Dissenting Shares.  Shares of Common Stock, Series AA
Preferred Stock or Nonredeemable  Preferred Stock held by any holder entitled to
relief as a dissenting  shareholder under Section 910 of the NYBCL (the "Company
Dissenting  Shares")  shall not  become the right to  receive  the Common  Stock
Conversion  Amount  in cash  (in the case of any such  share of  Company  Common
Stock),  Parent  Preferred  Stock  (in the case of any such  share of  Series AA
Preferred Stock) or any cash amount payable pursuant to Section  2.1(c)(iii) (in
the case of any such  share of  Nonredeemable  Preferred  Stock),  but  shall be
cancelled and converted  into such  consideration  as may be due with respect to
such shares pursuant to the applicable provisions of the NYBCL, unless and until
the right of such holder to receive fair cash value for such Company  Dissenting
Shares  terminates in accordance with Section 623 of the NYBCL. If such right is
terminated


                                      -11-

otherwise  than by the purchase of such shares by Company or LIPA Sub, then such
shares shall cease to be Company Dissenting Shares and shall represent the right
to receive the Common Stock  Conversion  Amount in cash (in the case of any such
share of Company Common Stock),  Parent Preferred Stock (in the case of any such
share of Series AA  Preferred  Stock) or any cash  amount  payable  pursuant  to
Section  2.1(c)(iii) (in the case of any such share of  Nonredeemable  Preferred
Stock).

               Section 2.3 Issuance of Parent Shares.

               (a) Deposit with Exchange Agent. As soon as practicable after the
Effective  Time,  Parent shall  deposit with such bank or trust company as shall
have been  mutually  agreeable to Company and  Authority  prior to the Effective
Time (the "Exchange Agent"), certificates representing Parent Shares required to
effect the issuances  referred to in Section  2.1(b) and Section  2.1(c)(i).  If
Company and Authority  shall not have agreed on the Exchange  Agent prior to the
Effective Time, the bank or trust company then serving as registrar and transfer
agent for the Series AA  Preferred  Stock  shall be  selected to act as Exchange
Agent for the  Series AA  Preferred  Stock.  The shares of Parent  Common  Stock
subscribed  for by the Exchange Agent as agent for the holders of Company Common
Stock  pursuant  to  Section  2.1(b)  and the  shares  of  Parent  Common  Stock
constituting the Transferred  Assets Stock Portion,  together with the shares of
Parent  Preferred Stock for which the shares of Series AA Preferred Stock are to
be exchanged pursuant to Section 2.1(c)(i),  are referred to herein collectively
as the "Parent Shares."

               (b)  Procedures  for  Issuance  of  Parent  Shares.  As  soon  as
practicable  after the  Effective  Time,  the Exchange  Agent shall mail to each
holder of record of a certificate or  certificates  (the  "Certificates")  which
immediately prior to the Effective Time represented outstanding shares of Series
AA Preferred  Stock or Company  Common  Stock,  as  applicable  (the  "Cancelled
Shares") that were cancelled and became  instead,  directly or  indirectly,  the
right to receive  the  applicable  Parent  Shares,  (i) a letter of  transmittal
(which shall specify that delivery shall be effected, and risk of loss and title
to the Certificates shall pass, only upon actual delivery of the Certificates to
the Exchange Agent) and (ii)  instructions for use in effecting the surrender of
the Certificates in exchange for certificates  representing  Parent Shares. Upon
surrender of a Certificate  to the Exchange Agent for  cancellation  (or to such
other  agent  or  agents  as  may be  appointed  by  agreement  of  Company  and
Authority),  together with a duly executed  letter of transmittal and such other
documents as the Exchange  Agent shall require,  the holder of such  Certificate
shall be entitled to receive a  certificate  representing  that number of Parent
Shares which such holder has the right to receive  pursuant to the provisions of
this Article II. In the event of a transfer of  ownership  of  Cancelled  Shares
which is not registered in the transfer records


                                      -12-


<PAGE>

of Company a certificate  representing the proper number of Parent Shares may be
issued to a transferee if the Certificate  representing such Cancelled Shares is
presented  to the  Exchange  Agent,  accompanied  by all  documents  required to
evidence and effect such transfer and by evidence  satisfactory  to the Exchange
Agent that any applicable stock transfer taxes have been paid. Until surrendered
as  contemplated  by this Section 2.3, each  Certificate  shall be deemed at any
time after the Effective  Time to represent  only the right to receive upon such
surrender the  certificate  representing  Parent Shares as  contemplated by this
Section 2.3.

               (c)  Distributions  with  respect  to  Unsurrendered  Shares.  No
dividends or other distributions  declared or made after the Effective Time with
respect to the Parent Shares with a record date after the  Effective  Time shall
be paid to the  holder of any  unsurrendered  Certificate  with  respect  to the
Parent Shares represented thereby until the holder of record of such Certificate
shall surrender such Certificate.  Subject to the effect of unclaimed  property,
escheat and other applicable laws,  following surrender of any such Certificate,
there shall be paid to the record holder of the certificates representing Parent
Shares issued in consideration  therefor,  without interest,  (i) at the time of
such  surrender,  the amount of dividends or other  distributions  with a record
date after the  Effective  Time  theretofore  paid with  respect to such  Parent
Shares and (ii) at the  appropriate  payment  date,  the amount of  dividends or
other  distributions  with a record date after the  Effective  Time but prior to
surrender  and a payment date  subsequent  to surrender  payable with respect to
such Parent Shares.

               (d) Closing of Transfer Books. From and after the Effective Time,
the stock  transfer  book of the Company  shall be closed and no transfer of any
capital stock of the Company shall  thereafter be made.  If, after the Effective
Time,  Certificates  are  presented to the Company,  they shall be cancelled and
exchanged for certificates representing the appropriate number of Parent Shares,
as provided in this Section 2.3.

               (e) Termination of Exchange Agent. Any certificates  representing
Parent Shares  deposited  with the Exchange Agent pursuant to Section 2.3(a) and
not exchanged  within one year after the Effective Time pursuant to this Section
2.3 shall be returned by the Exchange  Agent to Parent,  which shall  thereafter
act as Exchange Agent.  Parent shall not be liable to any person for such shares
delivered to a public official  pursuant to any applicable  abandoned  property,
escheat or similar law.

                               ARTICLE III

extent  owned,  leased and  operated  and to carry on its  business as it is now

delivered  by  Authority  and  LIPA  Sub and,  assuming  the due  authorization,
execution and delivery hereof by the other  signatories  hereto,  this Agreement

will not, result in a material  Violation  pursuant to any provisions of (i) the
certificate of  incorporation,  by-laws or similar  governing  documents of LIPA
Sub, (ii) subject to obtaining the Authority Required Statutory  Approvals,  any

in order to make such statement not misleading.

               Section 5.4 Ownership of LIPA Sub; No Prior Activities.  LIPA Sub
is a direct,  wholly owned subsidiary of Authority and was formed solely for the
purpose of engaging in the  transactions  contemplated by this Agreement.  As of

       dealings with them.  Company and the Company  Subsidiaries  may, with the
       prior approval of Authority or LIPA Sub,  engage in  transactions  out of
       the ordinary  course of business  relating to the Retained  Assets,  such
       approval not to be unreasonably withheld or delayed;  provided,  however,
       that the following will not be subject to Authority's or LIPA Sub's prior
       approval:  any transaction  involving the Transferred  Assets;  provided,
       however, that such approval will be required for (A) any transaction that

       of the Generation Purchase Right Agreement or (B) any transaction whereby
       Company  enters  into  a  capacity  or  transmission  purchase  agreement
       relating to the  purchase of more than 75 megawatts of capacity or having

       Company  Subsidiaries  shall  make any  change  in the  line of  business
       involving  the Retained  Assets in which it engages as of the date hereof
       which  involves  any  material  investment  of assets or resources or any
       material  exposure to liability or loss to the Retained Assets taken as a
       whole.

               (i) Affiliate Transactions. Except as set forth in Section 6.1(i)
       of the Parent Disclosure Schedule, neither Company nor any of the Company
       Subsidiaries  shall enter into any material agreement or arrangement with
       any  of  their  respective  affiliates  (other  than  those  wholly-owned
       subsidiaries  which will constitute  Retained Assets) on terms materially
       less  favorable to such party than could be  reasonably  expected to have
       been obtained with an unaffiliated third party on an arm's-length basis.

               (j)  Cooperation,  Notification.  Parent and Company  shall,  and
       shall  cause the  Company  Subsidiaries  to, (i) confer on a regular  and
       frequent basis with one or more  representatives of Authority or LIPA Sub
       to discuss,  subject to applicable law, material  operational matters and
       the  general  status of its  ongoing  operations;  (ii)  promptly  notify
       Authority  or  LIPA  Sub  of any  significant  changes  in its  business,
       properties, assets, condition (financial or other), results of operations
       or prospects;  (iii) advise  Authority or LIPA Sub of any change or event
       which has had or,  insofar as reasonably  can be foreseen,  is reasonably
       likely to result in a Material Adverse Effect;  and (iv) promptly provide
       Authority  or LIPA Sub with  copies  of all  filings  made by  Parent  or
       Company  or any of the  Company  Subsidiaries  with any state or  federal
       court,  administrative agency, commission or other Governmental Authority
       in connection with any Basic Agreement and the transactions  contemplated
       hereby and thereby or the Retained Assets.

               (k) Rate Matters.  Parent and Company shall,  and shall cause the
       Company  Subsidiaries  to, notify Authority or LIPA Sub of any changes in
       its or Company's rates or charges (other than  pass-through fuel rates or
       charges,  but  including,  without  limitation,  gas  rates or  charges),
       standards  of  service  or  accounting  from  those in effect on the date
       hereof.  Without  the consent of  Authority  (which  consent  will not be
       unreasonably withheld), Company shall not file or prosecute any rate case
       or other nonroutine  proceeding  before the Public Service  Commission of
       the State of New York (the "PSC") or FERC or any appeal therefrom, except
       for cases or proceedings (i) relating solely to pass-through  fuel or gas
       rates or charges,  (ii)  required to be made by order of the PSC or FERC,
       (iii)  relating  solely  to the  Transferred  Assets  or  (iv)  involving
       commercial  or  contractual  disputes  which are  required to be resolved
       through such proceedings;  provided,  however, that if Company reasonably
       believes that a matter threatens the financial  viability of Company,  it

       Company or the Company Subsidiaries.

               (r)  Permits.  Parent  and  Company  shall,  and shall  cause the

acknowledge  that  certain  information  that may be  furnished  pursuant to the
provisions of this Agreement may be confidential and proprietary to Company. The

information  upon request under applicable law. The Company shall have the right
to request  Authority in writing not to publicly  disclose any information which
Company  believes to be  confidential  or proprietary  and not subject to public
disclosure  under  applicable  law, and such request will be  accompanied  by an
explanation of its reasons for such belief. Any information which is the subject
of such a request  shall be  clearly  marked on all pages,  shall be bound,  and
shall be  physically  separate  from all  non-confidential  and  non-proprietary
information.  At Company's  request,  Authority  and its  Representatives  given

confidentiality  agreement in a mutually  acceptable form, subject to applicable
law.

harmless and defend  Authority  against all losses incurred from the withholding
from public disclosure of information  designated as confidential or proprietary
by Company or otherwise requested by Company to be withheld.

               (c)  Previously  Furnished  Information.  Company  hereby permits
Authority and its Representatives to obtain all information previously furnished
by Company to Bear, Stearns & Co. Inc. and certain other persons pursuant to the
letter  dated  October 11, 1995,  (as amended to date)  subject to the terms and
conditions  of this  Section  7.7.  Authority  agrees that all such  information
(other than information  described in clauses (1), (2) or (3) of Section 7.7(e))
shall be deemed to be  delivered  to Authority  pursuant to the  procedures  set
forth  in  Section  7.7(a)  for  the  purpose  of  identifying  confidential  or
proprietary information.

               (d)  Restriction  on Use.  Authority and LIPA Sub may not use any
confidential or proprietary  information  disclosed to either of them by Company
(other than information  described in clauses (1), (2) or (3) of Section 7.7(e))
in taking any action  described in clauses (a),  (b), (c) or (d) of Article X at
any time after the date hereof.

               (e) Permitted  Disclosures.  Notwithstanding  any confidential or
proprietary   designation  thereof  by  Company,   Authority  may  disclose  the
following:  (1) information  which is known to Authority without any restriction
as to disclosure or use at the time it is furnished, (2) information which is or
becomes generally  available to the public without breach of any agreement,  (3)
information  which  is  received  from  a  third  party  without  limitation  or
restriction on such third party or Authority at the time of  disclosure,  or (4)
following  notice  to  Company  pursuant  to  subsection  (b) of  this  Section,
information  which , in the opinion of counsel for Authority,  is required to be
disclosed   under  any  applicable  law,  an  order  of  a  court  of  competent
jurisdiction, or a lawful subpoena.

               Section 7.8 Certain Litigation.

               (a)  Class  Settlement.   After  the  date  hereof,  Company  and
Authority  shall  jointly  file an  appropriate  motion  before the court having
jurisdiction  over the Class  Settlement  (as  hereinafter  defined) to obtain a
modification  of the final order  approving  such Class  Settlement  which would
permit the payment in full at the Closing of all amounts  remaining  unpaid with
respect to such Class Settlement,  discounted to such present value as Authority
and  Company  may  agree and such  court may  approve.  As used  herein,  "Class
Settlement"  shall mean the class  settlement which became effective on June 28,
1989 and resolved a civil  lawsuit  against  Company  brought  under the federal
Racketeer Influenced and Corrupt Organizations Act.

               (b) Tax Cases. With respect to all tax cases relating to property
taxes or payments in lieu of property taxes assessable against any of the assets
and  properties  of Company as of the date hereof,  and other similar tax claims
arising  prior to the Closing Date (which  shall  constitute  Retained  Assets),
Company will enter into appropriate standstill agreements and


                                      -34-

maintain  the current  status of such cases;  provided,  however,  if any taxing
authority increases,  directly or indirectly, or purports to increase,  directly
or  indirectly,  the  assessed  value of any  Transferred  Asset  (other than in
respect of property additions or general increases in assessments), then Company
may pursue any  judicial  remedy it deems  advisable  in  connection  therewith.
Notwithstanding the foregoing, if any taxing authority, at any time prior to the
Closing,  asserts a claim for  property  taxes or  payments  in lieu of property
taxes which Company reasonably  believes is not authorized by statute or asserts
a right to value a taxable  property in a method other than in  accordance  with
applicable  New York State  rules and  regulations,  then  Company may take such
actions as it reasonably  determines to be necessary or advisable to protect its
interests,  but shall not otherwise pursue its claims pending the Closing or the
termination of this Agreement.

               (c) Phase I Rebates.  Upon the Closing,  Parent will  immediately
pay  Authority  $15  million in respect of the Phase I judgment  relating to the
Shoreham property tax case for distribution to ratepayers.

connection   with  this  Agreement  and  any  other  Basic   Agreement  and  the
transactions contemplated hereby (including, without limitation, any termination
fees and expense  reimbursements  payable by Company  pursuant  to the  Exchange
Agreement or to its officers or  directors  in respect of  severance,  change of
control  or  similar  agreements)  shall  be paid by the  party  incurring  such
expenses.  Any such cost or expense of Company not paid or otherwise  discharged
at or prior  to the  Closing  shall  be paid or  reimbursed  by  Parent  and the
Transferee Subsidiaries pursuant to the Parent Liabilities Undertaking and shall
not be included in the Closing Date Balance Sheet.

               Section 7.10 Further Assurances.  Each party will, and will cause
its  Subsidiaries  to, execute such further  documents and  instruments and take
such further  actions as may reasonably be requested by any other party in order
to consummate the transactions  contemplated hereby in accordance with the terms
hereof.

               Section  7.11  Purchase  Price  Allocation.  At or  prior  to the
Closing,  the  parties  shall  jointly  prepare and agree to an  allocation  for
federal income tax purposes pursuant to Section 1060 of the Code of the purchase
price payable by Parent in respect of the transfer of the Transferred Assets.

               Section 7.12 Receipt of Consents and Approvals. Each party agrees
to respond  promptly to any  request for any consent or approval  from any other
party  contemplated  by this  Agreement and any third party consent or statutory
approval  required  hereunder.  Each party shall designate  representatives  who
shall be authorized to address any request for any such consents or


                                      -35-


<PAGE>

approvals. Any act of any such representative with respect to such approvals and
consents shall be binding upon the party that designates such representative.

               Section 7.13 Certain Other  Matters.  The provisions set forth in
Schedules D (Tax Matters), E (Employment Matters) and F (Future Rights) attached
hereto are hereby  incorporated  by  reference  as if set forth  herein in their
entirety.

               Section 7.14 Opinions of Counsel. In addition, Parent and Company
shall deliver to Authority such opinions of counsel for Parent and Company as to
the  agreements  to  be  entered  into  in  connection  with  the   transactions
contemplated  by  the  Basic   Agreements,   in  customary  form  for  financing
transactions,  as to the matters of law covered by the representations of Parent
and Company and the Transferee  Subsidiaries  in the Basic  Agreements,  similar
matters  of law with  respect  to such  other  agreements  and as to such  other
matters of law as Authority may reasonably  request,  together with  appropriate
certified authorizing resolutions and incumbency certificates.

               Section 9.1  Termination.  This Agreement may be terminated prior

Company and the Board of Trustees of Authority;

               (b) by either  Parent and Company,  on the one hand, or Authority
and LIPA Sub, on the other hand,  if the Closing  shall not have  occurred on or

the right to terminate  the  Agreement  under this  Section  9.1(b) shall not be

Agreement  has been the cause of, or resulted  in, the failure of the  Effective
Time to occur on or before  this date;  and  provided,  further,  that if on the
Initial  Termination  Date the  conditions  to the Closing set forth in Sections
8.1(b),  8.1(d) or 8.2(e) shall not have been fulfilled but all other conditions

proper exercise of their applicable  fiduciary duties, and  notwithstanding  all
concessions  which may be offered by  Authority  in  negotiations  entered  into
pursuant to clause (ii) below,  such  fiduciary  duties  would also  require the
directors  to  reconsider  such  commitment  as a result of such tender offer or
other written offer or proposal; and (ii) prior to any such termination, Company
shall, and shall cause its respective financial and legal advisors to, negotiate
with  Authority to make such  adjustments  in the terms and  conditions  of this

aggregate,  would or would be reasonably  likely to result in a Material Adverse
Effect,  and such  breaches  shall not have been  remedied  within 20 days after
receipt by Parent and Company of notice in writing  from  Authority,  specifying
the nature of such breaches and requesting that they be remedied, (ii) Parent or
Company shall have failed to perform and comply with, in all material  respects,
its  agreements and covenants  hereunder or under any other Basic  Agreement and
such  failure to perform or comply shall not have been  remedied  within 20 days

specifying  the nature of such failure and  requesting  that it be remedied;  or
(iii)  the Board of  Directors  of Parent  or any  committee  thereof  (A) shall
withdraw or modify in any manner  adverse to  Authority or LIPA Sub its approval
or  recommendation  of this Agreement or the other Basic  Agreements,  (B) shall
fail to reaffirm such approval or recommendation  upon Authority's or LIPA Sub's
request, or (C) shall resolve to take any of the actions specified in clause (A)

of  Authority  and LIPA Sub made  herein as of the date hereof  which  breaches,
individually or in the aggregate,  would or would be reasonably likely to result
in a Material  Adverse  Effect,  and such breaches  shall not have been remedied
within 20 days after  receipt by  Authority  of notice in writing  from  Parent,
specifying  the nature of such  breaches and  requesting  that they be remedied,
(ii)  Authority  shall have failed to perform and comply  with,  in all material
respects,  its  agreements  and  covenants  hereunder  or under any other  Basic
Agreements,  and such failure to perform or comply shall not have been  remedied

               Section 11.10 Alternative Dispute Resolution.

               (a)  Any  dispute  arising  out of or  relating  to any  covenant
contained in any Schedule to this Agreement shall be resolved in accordance with
the procedures  specified in this Section 11.10, which shall constitute the sole
and exclusive  procedures  for the  resolution of such  disputes,  except to the
extent any such Schedule expressly provides another dispute resolution process.

               (b) The  parties  agree  to use  their  best  efforts  to  settle
promptly  any  disputes or claims  arising out of or relating to this  Agreement
through negotiation  conducted in good faith between executives having authority
to reach such a settlement. If either party hereto shall so request, the parties
shall  mutually  agree on the  selection  of a mediator  who shall  mediate  the
negotiations, which shall be non-binding.

               All  negotiations  and  mediation  discussions  pursuant  to this
paragraph are  confidential  and shall be treated as compromise  and  settlement
negotiations  for purposes of Federal Rule of Evidence 408 and applicable  state
rules of evidence.

               (c) Any dispute  arising out of relating to any  Schedule to this
Agreement or the breach, termination, or validity thereof, which dispute has not
been resolved by a negotiation  or mediation as provided in paragraph (b) hereof
within 60 days from the date that either  negotiations  or mediation  shall have
been first  requested,  shall be settled by  binding  arbitration  before  three
independent and impartial  arbitrators in accordance with the then current rules
of the  American  Arbitration  Association,  except to the extent such rules are
inconsistent with any provision of this Agreement,  in which case the provisions
of this Agreement shall be followed, and except that the arbitrations under this
Agreement shall not be administered by the American Arbitration Association. The
Arbitrators  shall be (i)  independent of the parties and  disinterested  in the
outcome  of  the  dispute,  (ii)  attorneys,  accountants,  investment  bankers,
commercial bankers or engineers familiar with contracts  governing the operation
of electric utility assets, and (iii) qualified in the subject area of the issue
in dispute.  For purposes of the  preceding  sentence,  residents of Long Island
shall not be  considered  interested  merely by virtue of their  residence.  The
Arbitrators  shall be  chosen  by the  parties,  with each  party  choosing  one
arbitrator and those arbitrators choosing the third arbitrator.  Judgment on the
award  rendered by the  Arbitrators  may be entered in any court in the State of
New York having jurisdiction  thereof. If either party refuses to participate in
good faith in the negotiations or mediation  proceedings  described in paragraph
(b) hereof,  the other may initiate  arbitration  at any time after such refusal
without  waiting for the expiration of the 60 day period.  Except as provided in
Paragraph (d) hereof relating to provisional  remedies,  the  Arbitrators  shall
decide all aspects of any dispute


                                      -45-


<PAGE>

brought to them including  attorney  disqualification  and the timeliness of the
making of any claim.

               (d)  Either  party may,  without  prejudice  to any  negotiation,
mediation,  or  arbitration  procedures,  proceed  in  any  court  of  competent
jurisdiction  to seek  provisional  judicial  relief  if, in such  party's  sole
discretion,  such action is necessary to avoid imminent  irreparable  harm or to
preserve  the  status quo  pending  the  conclusion  of the  dispute  procedures
specified in this Section 11.10.

               (e) The  Arbitrators  shall have no authority  to award  punitive
damages  or any other  damages  aside  from the  prevailing  party's  actual and
consequential  damages,  plus  interest  thereon at the Base  Interest  Rate (as
defined in the Management Services Agreement) accrued from the date such damages
were incurred.  The Arbitrators shall not have the authority to make any ruling,
finding,  or award  that does not  conform to the terms and  conditions  of this
Agreement.

               (f) The  Arbitrators  may award  reasonable  attorneys'  fees and
costs of the arbitration.

               (g) Any  claim  under any  Schedule  to this  Agreement  shall be
time-barred,  regardless of any statute of limitations periods provided by state
or  federal  law,  unless  negotiation  or  mediation  with  respect  thereto is
commenced  with respect to such claim within  twelve  months after the basis for
such claim has been discovered.

               (h)  The  Arbitrators  shall  have  the  discretion  to  order  a
pre-hearing  exchange  of  information  by  the  parties,   including,   without
limitation,  the production of requested documents, the exchange of summaries of
testimony of proposed  witnesses,  and the examination by deposition of parties.
Each of the  parties  agrees to  produce  all such  requested  documents  and to
deliver  to the other a  certificate,  executed  by a senior  executive  of such

                                   Schedule B

                          Principles and Procedures for
                    Finalizing the Transferred Asset Schedule

A.   Procedures

1.   Each of Company and Authority will promptly  designate the  representatives
     to form a task  force  (the  "Task  Force")  to  review  and  finalize  the
     descriptions   of  Transferred   Assets  in  order  to  provide  for  legal
     descriptions  of such  Assets.  The parties  agree to use,  and to instruct
     their  representatives  to use,  their best  efforts to provide  full legal
     descriptions  (as  hereinafter  defined)  of  the  Transferred  Assets  for
     inclusion as an appendix to this Agreement by December 31, 1997.

2.   If the Task  Force is  unable  at any  time to  agree  upon the full  legal
     description or the best feasible legal description (as hereinafter defined)
     of any  Transferred  Asset,  certain  executives  of Company and  Authority
     designated from time to time by the parties (the  "Executives")  shall meet
     to discuss and resolve any disagreements.

3.   If the  Executives  are unable to agree  within 14 days of the  referral to
     them of any such  dispute (or such other  period of time as the parties may
     agree),  and the parties are unable to agree upon an appropriate  mediation
     procedure  with respect to such  dispute,  any such  disagreement  shall be
     finally  settled by  arbitration.  The  arbitration  shall be  conducted in
     accordance   with  the  American   Arbitration   Association's   commercial
     arbitration rules in effect at the time of arbitration,  except as modified
     herein or by mutual  agreement of the parties.  The seat of the arbitration
     shall be Mineola or Hauppauge,  New York, provided that the arbitrators may
     hold hearings in such other  locations as the  arbitrators  determine to be
     most convenient and efficient for all the parties under the  circumstances.
     Notwithstanding  anything to the contrary in Section 11.6, the  arbitration
     shall be governed by the Federal  Arbitration Act. The arbitration shall be
     conducted  by  an  arbitration   panel  consisting  of  three   independent
     individuals  with  relevant  professional  experience in commercial or real
     estate  law or  engineering  and  shall be  designated  by the  parties  by
     September  30,  1997 or,  if no such  designation  shall  be  made,  by the
     American  Arbitration  Association.  Any award rendered by the  arbitrators
     shall be in writing and shall be final and binding  upon the  parties,  and
     may include an award of costs,  including  reasonable  attorneys'  fees and
     disbursements. Judgment upon the award rendered may be


<PAGE>

     entered in any court  having  jurisdiction  thereof or having  jurisdiction
     over the parties or their assets.  The parties shall mutually  instruct the
     arbitrators to limit the time and scope of discovery to the greatest extent
     practicable and request the arbitrators to provide a decision as rapidly as
     practicable,  in each case  consistent  with the  interests of justice,  it
     being the intention of the parties that any arbitration  under this Section
     3 be  commenced,  conducted  and  completed,  and a decision  rendered,  as
     rapidly as practicable.

4.   Each   determination  made  by  the  Task  Force,  the  Executives  or  the
     arbitrators  shall be documented  as an appendix to this  Agreement and may
     take the form of an amendment and restatement of the applicable Schedule or
     any Annex thereto.

5.   Each of Company and  Authority  may at any time upon 10 days' prior written
     notice to the other designate one or more persons to act as representatives
     on the Task Force as additions to or replacements of any person  previously
     designated  by such  party.  Each  such  party may also by  similar  notice
     designate a replacement Executive for such party.


B.   Principles

1.   For  purposes  of this  Schedule B, "full legal  description"  means,  with
     respect to any  Transferred  Asset,  a description  and  customary  related
     conveyancing documentation of the kind ordinarily used to describe property
     of the same type and to document its transfer.  The parties acknowledge and
     agree that it may not be possible to provide full legal descriptions of all
     Transferred  Assets due to factors  not within the control of any party and
     that for any such  Transferred  Asset the Task Force is directed to produce
     the best feasible legal description consistent with the requirements of the
     parties'  respective  operations  after the  Closing and  applying  prudent
     business judgment (the "best feasible legal description").

2.   In evaluating the requirements of the parties, the Task Force shall be duly
     mindful  of  any  requirements  imposed  on  Authority  by  reason  of  the
     tax-exempt  financing  required in order to fund the Cash  Purchase  Price.
     With respect to Parent, the parties acknowledge and agree that Parent shall
     bear the risk of any  deficiency in the legal  description of a Transferred
     Asset  attributable  to the state of  Company's  records and  recordkeeping
     practices prior to Closing.

3.   For each  parcel of real  property  owned in fee by Company  ("parcel")  at
     which only the gas or generating business of Company is currently conducted
     and each  Common  parcel,  the form and  content of the legal  descriptions
     thereof and


                                       B-2


<PAGE>

     conveyancing  documentation with respect thereto shall be determined by the
     Company  representatives on the Task Force,  subject to the second sentence
     of Section 2, consistent with the documentation by which title was acquired
     and local custom with respect to documenting transfers of property,  and to
     the  consent of the  Authority  representatives  on the Task  Force  (which
     consent will not be unreasonably withheld). As used herein, with respect to
     real property and fixtures on such real  property only "Common"  shall mean
     any  parcel  at  which  the gas and  generating  business  of  Company  are
     currently  conducted  in common and any other  parcel  (including,  without
     limitation,  any vacant or future use property  (except future use property
     held  primarily  for the T&D System) and  property  leased by Company to or
     from any third party) other than any parcel at which the  transmission  and
     distribution ("T&D") business of Company is currently conducted.

4.   For each  parcel at which (a) the gas,  generating  or Common  business  of
     Company and (b) the T&D  business of Company is  currently  conducted,  the
     identification  of Transferred  Assets shall be made in accordance with the
     following principles:

     a.   Fixtures  and  Structures.  The  parties  will refer to an  electrical
          one-line diagram which represents the typical  interconnection between
          (i) the T&D system (the "T&D  System")  constituting  a portion of the
          Retained  Assets  and (ii) the gas,  generating  or Common  facilities
          constituting a portion of the Transferred Assets. The division between
          (x) the T&D System and (y) the gas,  generating  or Common assets will
          be determined by applying to each parcel the  principles  reflected on
          such diagram.

     b.   Parcels.  The legal  description of the Transferred  Assets in certain
          parcels will be determined by reference to the  applicable  plot plans
          and parcel  maps for such  parcels  and the  division  between the T&D
          System and the gas, generating or Common assets set forth on such plot
          plans.  If as of the Closing  Date and as set forth in the  applicable
          parcel  maps any  parcel has been  improved  with any  Retained  Asset
          fixtures  that occupy less than 50% of such  parcel,  then such parcel
          will be presumed to be a Transferred  Asset and Authority will receive
          a perpetual  easement to use such parcel for its operations.  If as of
          the Closing  Date and as set forth in the  applicable  parcel maps any
          parcel has been improved with any Retained  Asset fixtures that occupy
          50% or more of such parcel,  then such parcel will be presumed to be a
          Retained  Asset and Company will  receive a perpetual  easement to use
          such parcel for its  operations.  Notwithstanding  the  preceding  two
          sentences, a parcel that would, pursuant


                                       B-3


<PAGE>

               to such sentences, be (i) classified as a Transferred Asset shall
               nonetheless  be classified as a Retained  Asset if an independent
               professional  engineer would reasonably conclude that the parcel,
               taken  as  a  whole,   is   significantly   more  in  the  nature
               functionally  of a T&D  asset  than a gas,  generating  or common
               asset or (ii) classified as a Retained Asset shall nonetheless be
               classified  as  a  Transferred   Asset  if  such  engineer  would
               reasonably  conclude that such parcel,  taken as a whole,  is not
               significantly more in the nature functionally of a T&D asset than
               a gas,  generating or common asset.  At  Authority's or Company's
               request,   the   parties   will   evaluate   in  good  faith  the
               practicability  of  subdividing a parcel  subject to this Section
               B.4 and, if the parties conclude that subdivision is practicable,
               will negotiate in good faith the terms and conditions of any such
               subdivision.

          c.   The parties will  negotiate in good faith to provide a reasonable
               reallocation of amounts  reflected in the Pro Forma Balance Sheet
               to reflect  any  variance  between  the  results  obtained by the
               application  of this  Schedule  B and the  corresponding  amounts
               reflected in the Pro Forma Balance Sheet.

          d.   Each  fixture  functionally  related  to the gas,  generating  or
               Common  business of Company  shall be a Transferred  Asset.  Each
               fixture functionally related to the T&D business of Company shall
               be a Retained Asset.

          e.   Company  shall  have the  right to  attach  equipment,  including
               telecommunications  equipment, to the T&D System at applicable or
               negotiated  rates on a  non-discriminatory  basis and  obtain all
               necessary  access  or  leasehold  rights  related  thereto  on  a
               non-discriminatory basis.

          f.   All legal and technical documentation primarily associated with a
               Transferred Asset (such as purchase orders,  title documentation,
               manufacturers'   and   distributors'   warranties,   governmental
               registrations,  insurance policies,  maintenance  records,  etc.)
               shall be Transferred Assets.

5.   Any easement that is primarily for the  installation and maintenance of the
     T&D System will be a Retained  Asset,  and Authority  will provide  Company
     with access rights for the  installation and maintenance of any Transferred
     Asset situated on such easement. Any easement that is not primarily for the
     installation and maintenance of the T&D system will be a Transferred Asset,
     and Company will provide  Authority with access rights for the installation
     and maintenance of any Retained Asset situated on such easement.


                                       B-4


<PAGE>

     The parties will negotiate in good faith  adjustments to the principles set
     forth in this  Section B.5 to the extent  necessary  or advisable to reduce
     costs and enhance operational efficiency.

6.   For each  parcel  referred  to in Section 4 for which no plot plan has been
     provided,  the parties will  negotiate in good faith to provide  reasonable
     rights  of  access  from  public  roads,  services  and  facilities  to the
     separated  facilities  of  Company  or  Parent,  as the case may be,  at no
     additional cost.

7.   Company shall establish such recordkeeping  practices as shall be necessary
     to properly  designate each asset it purchases or otherwise  acquires after
     the date hereof as a  Transferred  Asset or a Retained  Asset in accordance
     with  applicable Task Force,  Executive and  arbitration  decisions made in
     accordance herewith.

8.   All motor  vehicles  owned or  purchased  by Company  and all  interest  of
     Company in any leased  motor  vehicles,  including  "bucket  trucks",  used
     primarily in the T&D business shall be Retained Assets.

9.   Applicable FERC accounting  principles will be considered in evaluating the
     proper classification of any asset.

appropriate, shall undertake and complete the following responsibilities:

                  (a) Site Access.  Upon reasonable notice by Authority,  Parent
and Company shall permit Authority, its representatives,  consultants, designees

characteristics  and  limitations,  reliability,  generation  operation and cost
impacts   associated  with  changes  in  generation  plant,  load  growth,   and
transmission  facility  improvements,   additions  and  interconnections.   Such

shall  have the right to review  such Tax Return  prior to the  filing  thereof.
Authority shall notify Parent of any reasonable objections Authority may have to
any items set forth in such draft Tax Returns, and Authority and Parent agree to
consult and resolve in good faith any such  objection  and to mutually  agree to
the form and substance of such Tax Return. Such Tax Returns shall be prepared in
a manner  consistent  with prior practice of the Company with respect to Returns
concerning  the income,  properties  or  operations  of the  Company  (including
elections and accounting methods and conventions) and with this Agreement except
where a specific contrary practice is required by law or regulation or otherwise
agreed to prior to the filing  thereof.  Upon the  agreement  of  Authority  and
Parent as to the form and  substance  of any such Tax  Return,  Authority  shall
cause Company to file such Tax Return.  Parent shall pay to Authority at least 5
days prior to the due date of any such Tax Return,  all Taxes that are reflected
on such Tax Return that have not theretofore been paid to the applicable  taxing
authority or reflected in Tax Reserves on the Closing Date Balance Sheet.

         4. Tax Periods  Beginning  Before and Ending  After the  Closing  Date.
Parent shall  prepare or cause to be prepared any Tax Returns of the Company for
Tax periods  which begin before the Closing Date and end after the Closing Date.
Parent shall  provide a  preliminary  draft of any federal  income Tax Return at
least 60 days prior to the  scheduled  due date for such Tax Return (with regard
to any  extensions  in  effect  on  such  date),  and  Parent  shall  provide  a
substantially final draft of any Tax Return relating to any other Taxes at least
5 business days prior to their due date  (including any  extensions).  Authority
shall notify Parent of any reasonable objections Authority may have to any items
set forth in any such draft Tax  Returns,  and  Authority  and  Parent  agree to
consult and resolve in good faith any such  objection  and to mutually  agree to
the form and substance of such Tax Return.  Except as otherwise provided in this
Agreement,  such  Tax  Returns  shall  be  prepared  or  completed  in a  manner
consistent with prior practice of the Company with respect to Returns


                                      - 4 -

concerning  the income,  properties  or  operations  of the  Company  (including
elections and accounting methods and conventions) and with this Agreement except
where a specific contrary practice is required by law or regulation or otherwise
agreed to by  Authority  prior to the  filing  thereof.  Upon the  agreement  of
Authority  and  Parent  as to the form  and  substance  of any such Tax  Return,
Authority  shall  cause  Company to file such Tax  Return.  Parent  shall pay to
Authority  at least 5 days prior to the due dates of such returns the portion of
such Taxes which relate to the portion of such Tax period  ending on the Closing
Date  determined  as provided in this  Schedule D, to the extent such Taxes have
not theretofore been paid by Parent,  Company or any Company Subsidiary prior to
the Closing Date to the  applicable  taxing  authorities or are not reflected in
Tax Reserves on the Closing Date Balance Sheet provided,  however, any liability
which is discovered  after the Closing Date which under the rules of the PSC (at
the date hereof) is an electric  ratepayer expense which has not previously been
charged or credited to  ratepayers  shall be  considered a liability or asset of
the  Authority.  For purposes of this  Schedule,  in the case of any Tax that is
imposed on a periodic  basis and is payable for a Tax period that  includes (but
does not end on) the Closing Date,  the portion of such Tax which relates to the
portion of such Tax period  ending on the Closing  Date shall (x) in the case of
any Taxes  other  than Taxes  based  upon or  related to net or gross  income or
receipts,  be deemed to be the  amount of such  Taxes for the  entire Tax period
multiplied by a fraction the numerator of which is the number of days in the Tax
period ending on the Closing Date and the  denominator of which is the number of
days in the  entire  Tax  period,  and (y) in the case of any Tax based  upon or
related to net or gross  income or receipts be deemed  equal to the amount which
would be payable if the relevant Tax Period  ended on the Closing  Date.  Parent
shall be  responsible  for the portion of such Taxes which relate to the portion
of the Taxable  period ending on the Closing Date including  without  limitation
Taxes  reflected in Tax Reserves on the Closing Date Balance  Sheet (as adjusted
pursuant to the  proviso in the second  preceeding  sentence)  and shall pay the
amount  of such  Taxes  to  Authority  except  to the  extent  such  Taxes  have
theretofore  been paid by  Parent,  Company  or any  Company  subsidiary  to the
appropriate  tax  authority or are reflected in such Tax Reserves on the Closing
Date Balance Sheet (taking into account such  adjustments).  All  determinations
necessary to give effect to the foregoing  allocations shall be made in a manner
consistent with prior practice of the Company. Notwithstanding the foregoing and
except as provided in Schedule E, if requested to do so by Parent,  and provided
Parent has supplied the necessary funds therefore,  Company shall make a payment
or payments at such time as directed by Parent  prior to the last day of the Tax
Period that  includes  the Closing Date with respect to any expense or liability
of the  Company  which  accrues  prior to the  Closing  Date and the tax benefit
attributable  to such  payment  shall be deemed  attributable  to the Tax Period
ending on or before the Closing Date. Authority shall reimburse Parents for such
funds to the


                                      - 5 -


<PAGE>

extent and at such times as such reimbursement may be appropriate.

         5. Certain  Taxes.  Notwithstanding  any provision of this Agreement to
the  contrary,  all Taxes  incurred by Company  with  respect to the transfer to
Parent or the Transferee Subsidiaries of the Transferred Assets the distribution
of the Parent Shares,  and the sale of the New Parent  Preferred Shares shall be
deemed to relate to the portion of the  relevant  taxable  period  ending on the
Closing  Date for  purposes  of the  preceding  Section 4, and in no event shall
Parent or its  Subsidiaries be responsible for the payment or  reimbursement  to
Authority or Company of Taxes to the extent the right to recover such Taxes from
ratepayers  would have been  recordable  as an asset on the Closing Date Balance
Sheet and were not so recorded,  other than federal  income taxes arising out of
the transactions contemplated by the Acquisition Agreement.

         6. Refunds and Tax Benefits. Except to the extent that any amount would
be returnable to electric  ratepayers under PSC rules (at the date hereof),  any
refunds of taxes based on gross or net income that are  received by Authority or
its  Subsidiaries  subsequent  to the Closing  Date,  and any  amounts  credited
against any such Taxes to which Authority and its Subsidiaries  become entitled,
that relate to Tax periods or portions  thereof  ending on or before the Closing
Date shall be for the account of Parent,  and Authority shall pay over to Parent
any such refund or credit within 15 days after receipt thereof,  unless any such
refund or amount  results in a liability for such Taxes being imposed on Company
relating to Tax periods or portions  thereof  ending after the Closing  Date, in
which  case the  amount  paid to Parent  shall be  reduced by the amount of such
liability.

         7. Cooperation on Tax Matters.

                  (a) Parent shall have the right to represent  the interests of
Company in any Tax audit or administrative  or court proceeding  relating to Tax
Returns  described  in  Paragraphs  3 and 4 with  respect to which Parent may be
liable for Taxes  pursuant to this  Agreement  (including  any such  proceedings
relating to Company or any Company  Subsidiary)  and shall control such audit or
proceeding with respect to Taxes for which it is responsible  under paragraphs 3
& 4  of  this  Schedule  D  consistent  with  the  Liabilities  Undertaking  and
Indemnification  Agreement (Exhibit F); provided,  however, that Authority shall
have the right to participate in any such audit or proceeding to the extent that
any such audit or proceeding  may affect the Tax liability of Authority,  any of
its  affiliates  or Company for any period  ending after the Closing Date and to
employ  counsel  of  its  choice  at  its  own  expense  for  purposes  of  such
participation  and shall control such audit or proceeding  with respect to Taxes
for which it is responsible under paragraph 4 of this Schedule D consistent with
the  Liabilities   Undertaking  and   Indemnification   Agreement  (Exhibit  G).
Notwithstanding anything to the contrary contained or implied in this Agreement,
without  the  prior  written  approval  of  Authority,  neither  Parent  nor any
affiliate  of Parent  shall  agree or consent to  compromise  or settle,  either
administratively


                                      - 6 -


<PAGE>

or after the commencement of litigation,  any issue or claim arising in any such
audit or proceeding,  or otherwise agree or consent to any Tax liability, to the
extent that any such compromise, settlement, consent or agreement may affect the
Tax  liability  of  Authority  or Company  for any Tax Period  ending  after the
Closing Date. Except to the extent required by law, neither Authority nor any of
its  Subsidiaries  shall  take  any  position  with  respect  to  Taxes  that is
inconsistent  with any position  taken by the Company  prior to the Closing Date
and shall file no amended Tax Returns  with  respect to any Tax Period that ends
before or includes the Closing Date.  Neither Parent nor any affiliate of Parent
shall,  without the prior  written  consent of  Authority,  file, or cause to be
filed,  any amended Tax return or claim for Tax refund,  with respect to Company
to the extent that any such filing may affect the Tax  liability  of  Authority,
any of its  affiliates,  or Company for any Tax Period  ending after the Closing
Date.

                  (b) Parent,  Authority, and their Subsidiaries shall cooperate
fully,  as and to the  extent  reasonably  requested  by  the  other  party,  in
connection  with the filing of Tax  Returns  pursuant to this  Schedule  and any
audit, litigation, refund claim, or other proceeding with respect to Taxes. Such
cooperation shall include the retention and (upon the other party's request) the
provision of records and information  which are reasonably  relevant to any such
audit, litigation, refund claim, or other proceeding, making employees available
on a mutually convenient basis to provide additional information and explanation
of any material  provided  hereunder,  and executing powers of attorney to allow
Parent and its representatives to exercise the rights herein enumerated. Parent,
Authority, and their Subsidiaries agree (A) to retain all books and records with
respect to Tax matters  pertinent to the Company  relating to any taxable period
beginning  before  the  Closing  Date  until the  expiration  of the  statute of
limitations  (and,  to the extent  notified by the other party,  any  extensions
thereof) of the respective taxable periods, and to abide by all record retention
agreements  entered  into with any taxing  authority,  and (B) to give the other
party reasonable written notice prior to transferring,  destroying or discarding
any such books and records  and, if the other party so  requests,  Authority  or
Company,  or Parent or its  Subsidiaries,  as the case may be,  shall  allow the
other party to take possession and control of such books and records.

                  (c) Authority and Parent further agree,  upon request,  to use
their  best  efforts  to  obtain  any  certificate  or other  document  from any
governmental  authority  or any other  Person as may be  necessary  to mitigate,
reduce or eliminate  any Tax that could be imposed  (including,  but not limited
to, with respect to the transaction contemplated in this Agreement).

         8. Any liability arising after the Closing by reason of failure to meet
the requirements of Section 337(d) and the


                                      - 7 -


<PAGE>

regulations  thereunder  because of the action of a  regulatory  agency,  or any
mistatements made to such regulatory agency,  shall be allocated to Authority if
the  agency  is an agency  of New York  State and to Parent if the  agency is an
agency of the Federal government.

                                   Schedule E

                               Employment Matters


I.   Compensation and Benefits

     Discharge  of  Company  liability  with  respect to  employee  &  executive
     compensation and benefits.

     1.   Parent  will  become  the  successor  employer  to  Company  under the
          collective  bargaining  agreements  to which  Company is a party.  All
          employees  of  Company  will be  offered  employment  by  Parent or an
          affiliate of Parent, effective as of the Closing. Employees who do not
          accept employment with Parent or an affiliate shall be terminated.

     2.   Company will make the following  arrangements  with respect to payment
          of its  liabilities  under  its  compensation  and  benefit  plans and
          programs prior to the end of the tax year within which the date of the
          Closing falls:

          a.   With   respect   to   any   welfare    benefit   plan   providing
               post-retirement  welfare  benefits that under PSC rules in effect
               at the date  hereof is a  ratepayer  expense,  Company,  prior to
               Closing,  and  Parent,  prior to the close of the tax year  which
               includes the date of the Closing,  may fund any such liability by
               paying to the trustee of any employee benefit trust the amount of
               the projected  benefit  obligation  accrued up to the Closing for
               welfare  benefits under such plans  (whether  vested or unvested)
               which  Company  or Parent  (as the case may be) has a  reasonable
               basis to believe is deductible  for Federal  income tax purposes.
               To the extent not  otherwise  charged to Company  pursuant to the
               Basic Agreements or any other  contractual  relationship  between
               Parent,  any  affiliate  of Parent,  Authority  or  Company  (and
               otherwise without regard to any other  contractual  relationships
               between Parent, Company or Authority), Authority shall pay Parent
               an  amount  equal  to the  amount  of the  portion  of the  post-
               retirement  liability  described in this paragraph that under the
               rules of the PSC in  effect  at the date  hereof  is an  Electric
               ratepayer  expense (an estimate of which amount is reflected as a
               regulatory  asset of Company on the Pro Forma Balance  Sheet,  at
               the  same  time  and  for  the  same  amount  that  the  Electric
               ratepayers   would  have  had  the  cost   attributable  to  such
               post-retirement  


<PAGE>

               liability  included in the cost of their  service under the rules
               of the PSC in effect at the date hereof  until such  liability is
               fully amortized.

          b.   Notwithstanding  any other  provision of the Agreement,  Company,
               prior to Closing,  and Parent, prior to the close of the tax year
               which includes the date of the Closing,  shall pay or arrange for
               the funding of any employee  compensation  or benefit  previously
               accrued (or which would be accrued upon an employee's termination
               of employment  from Company) which, in the judgment of Company or
               Parent (as the case may be), is reasonable  and which under rules
               of the  PSC in  effect  at the  date  hereof  is not a  ratepayer
               expense.

          c.   With  respect to any  employee or former  employee (or his or her
               spouse,  or other dependent or  beneficiary)  who qualifies for a
               benefit under a welfare  benefit  (including  severance)  plan or
               workers'  compensation  plan  because of an illness,  accident or
               other event  (including  termination of employment) that occurred
               on or prior to the  Closing,  Authority  shall pay or provide for
               the cost of continuing coverage of any such benefit not described
               in paragraph a, b, d, or e of this Section I.2, to the extent and
               at the time the cost of such  coverage is an  Electric  ratepayer
               expense  under PSC rules in  effect at the date  hereof.  Company
               prior to Closing,  and Parent, prior to the close of the tax year
               which includes the date of the Closing, may, subject to paragraph
               h  below,  contribute  funds  to a  trust  to  provide  for  such
               benefits.

          d.   With  respect  to  any  liability   for  the  projected   benefit
               obligations  accrued up to the Closing for pension  benefits that
               under  PSC rules in  effect  at the date  hereof  is an  Electric
               ratepayer expense (including,  but not limited to, benefits under
               either  qualified or  nonqualified  plans which alone or together
               with other  benefits are non-  discriminatory),  Company prior to
               Closing,  and  Parent,  prior to the close of the tax year  which
               includes  the date of the  Closing,  may,  subject to paragraph h
               below,  fund  such  benefits  (vested  or  non-vested)  under the
               actuarial methods, factors or assumptions set forth in the latest
               actuarial  reports with respect to such plans by  contributing to
               the  appropriate  trust up to the amount which  Company or Parent
               (as the  case  may be)  has a  reasonable  basis  to  believe  is
               deductible for Federal tax purposes.


                                      -2-

          e.   Company prior to Closing,  and Parent,  prior to the close of the
               tax year which includes the date of the Closing,  may, subject to
               paragraph  h  below,  pay any  accrued  benefit  or  compensation
               including accrued vacation pay that under the rules of the PSC in
               effect at the date hereof is a ratepayer expense.

          f.   Any liabilities  Company incurs for payments by Company  referred
               to in  paragraphs  a, c, d and e of this  Section  I.2  that  are
               attributable  to  employees  who were not,  prior to the Closing,
               employed  by,  or  whose   compensation  was  not  allocable  to,
               Company's gas business  shall be assumed by Parent at the Closing
               subject to Authority's  obligations pursuant to the last sentence
               of paragraph a and pursuant to paragraph c.

          g.   Any liabilities  Company incurs for payments by Company  referred
               to  in  paragraphs  a,  c,  d  and  e of  this  Section  I.2  and
               attributable  to  employees  who,  prior  to  the  Closing,  were
               employed by, or whose compensation is allocated to, Company's gas
               business,  and any liabilities Company incurs for payments by the
               Company  referred to in paragraph b of this Section I.2, shall be
               assumed by Parent at the Closing.

          h.   In the case of  liabilities  attributable  to employees  who were
               not, prior to the Closing, employed by, or whose compensation was
               not   allocable  to,   Company's  gas  business,   prefunding  or
               prepayment of such liabilities  under paragraph c, d or e of this
               Section I.2 shall require the prior written consent of Authority,
               which shall not be unreasonably withheld.

     3.   Provision for certain employee liabilities.

          a.   Effective as of the Closing,  Parent shall assume, or shall cause
               one or more of its  affiliates  to assume,  all of the  "Employee
               Plans"  described in Section II.1 of this  Schedule E,  including
               all  liabilities and assets  thereunder,  and the Parent (or such
               affiliate)  as plan  sponsor  shall  have the sole  authority  to
               appoint the plan trustees and named fiduciaries.

          b.   Notwithstanding the foregoing, and subject to the limitations set
               forth in this Section I.3, Parent or such  affiliate(s)  shall be
               entitled  to  charge  Authority  for  the  cost  of  funding  and
               maintaining the following  Employee Plans and related trusts,  


                                      -3-


<PAGE>

               to the extent such cost is  attributable  to  employees  who have
               been  employed  by  Company  prior  to the  Closing  (other  than
               employees  employed  by or who  provided  services  solely to the
               Company gas business) or who after the Closing  provide  services
               to  Company  or  Authority  under  any Basic  Agreement  or other
               contractual relationship between Parent or an affiliate of Parent
               and Company or the Authority:

               (i)  any qualified pension plan and trust;

               (ii) any benefit plan and trust providing post- retirement health
                    or life insurance benefits; and

               (iii)any other  Employee Plan and related trust which,  under the
                    current  rules  of the PSC in  effect  at the  date  hereof,
                    provides benefits which are properly a ratepayer expense.

          c.   No cost shall be charged to Authority  pursuant to Section  I.3.b
               to the extent such cost has been or will be charged to  Authority
               pursuant to the  Ancillary  Agreements  or any other  contractual
               relationship  between  Parent  or any  affiliate  of  Parent  and
               Company or the Authority.

          d.   The cost to be charged to  Authority  pursuant  to Section  I.3.b
               shall be subject to the following:

               (i)  With respect to any liability  which depends upon  actuarial
                    methods,  factors or assumptions,  Authority shall be liable
                    for,  or be  credited  with the effect  of,  the  difference
                    between  the  amount  funded  by  Authority  and the  amount
                    actually  required to provide  the  employee  benefits  with
                    respect  to  the  services   rendered  by  the  employee  to
                    Authority  either as (A) an employee of Company or Authority
                    or (B) an  employee  of Parent or its  affiliates  providing
                    services  to Company or  Authority.  The  proportion  of the
                    total  liability which shall be funded by Authority shall be
                    the amount of the actual liability  multiplied by a fraction
                    the numerator of which is the total months of service by the
                    employee for Company or service for Parent or any  affiliate
                    which is properly  charged to Company or  Authority  and the
                    denominator  of which  is the  total  number  of  months  of
                    service of the  employee  to both  Company and Parent or its
                    affiliate.


                                      -4-


<PAGE>

               (ii) To the extent that any liability for benefits incurred after
                    the  Closing  reflects  the  amount of  compensation  of the
                    employee,  the proportion of any such liability  which shall
                    be  funded  by  Authority  shall  be the  proportion  of the
                    employee's  compensation properly charged to Authority.  For
                    example, if an employee of Parent is charged only 50 percent
                    to Authority after the Closing,  Authority's  responsibility
                    for his pension  benefit  shall be one half of the amount of
                    the liability  attributable  to the  employee's  benefit for
                    such period of service.

          e.   Parent  and its  affiliates  shall  have the  right to alter  the
               benefits provided to their employees.  However, except as Parent,
               and Authority may otherwise  agree, to the extent any such change
               in benefits result in increased  costs, the effect of such change
               shall not be charged to Authority and  Authority's  liability and
               contribution  with respect to any such  employee who continues to
               render  services to Authority shall be determined as if the plans
               and  trusts of Company  continued  without  amendment,  change or
               termination.

          f.   The amount of any payments which Authority is required to make to
               any trustee under any employee  pension benefit plan as that term
               is  defined  in  Section  3(2) of ERISA or any  employee  welfare
               benefit plan as defined in Section 3(1) of ERISA shall be paid in
               time and amount as such  amount  would be  included  in the costs
               charged to ratepayers in accordance  with the rules of the PSC at
               the date hereof, with respect to the plans of utilities regulated
               by it, but in all events shall be in compliance  with  applicable
               funding rules under ERISA, the Code or other  applicable  Federal
               law.  Any  costs  incurred  by  any  trust  with  respect  to the
               determination  of the time and amount of any payment by Authority
               to such trust shall be borne by  Authority in  proportion  to the
               Authority's  pro rata share of the total benefit  liabilities  of
               such trust (on a present value basis), and otherwise by Parent or
               an affiliate of Parent.

          g.   (i)  Parent and the affiliates of Parent maintaining the Employee
                    Plans after the Closing  shall  submit  within 30 days after
                    the end of each calendar  quarter one  consolidated  invoice
                    for the cost to be charged to Authority  pursuant to Section
                    I.3.b  for  such  quarter,  together  with  such  supporting
                    documentation  as may be reasonably  requested 


                                      -5-


<PAGE>

                    by Authority.  Authority shall have thirty days from date of
                    receipt to pay such invoice.

               (ii) Notwithstanding the foregoing,  (A) if Authority  reasonably
                    requests   additional   supporting   documentation   or   an
                    explanation for a particular  invoice,  Authority shall have
                    at least thirty days following receipt of such documentation
                    or explanation to make such payment,  and (B) in the case of
                    any   invoice   exceeding   125%  of  the  invoice  for  the
                    immediately preceding calendar quarter, Authority shall have
                    the option to pay such invoice over a period of up to twelve
                    months,  with  interest  payable  quarterly  at an effective
                    interest rate equal to Parent's effective cost of borrowing.

               (iii)If  there  is  a   dispute   with   respect   to   actuarial
                    calculations   that  cannot  be  resolved  between  Parent's
                    actuary  and  Authority's  actuary,  the  dispute  shall  be
                    referred  to  a  third   actuary   selected  by  Parent  and
                    Authority, the cost of whom shall be borne equally by Parent
                    and  Authority.  Any  costs  (including  without  limitation
                    reasonable  attorneys' fees) incurred in connection with any
                    legal action taken to collect the amount so determined to be
                    payable by Authority shall be payable by Authority.

          h.   If any Basic  Agreement is terminated  and, as a result  thereof,
               Parent or an affiliate  thereof is replaced as  service-provider,
               Authority  shall  require  that any  successor  to Parent or such
               affiliate shall assume Parent's and such  affiliate's  rights and
               obligations  under this Section I.3,  and Parent,  Authority  and
               Company  shall enter into such  agreements  as are  necessary  to
               separate the obligations for which the new service-provider  will
               be  responsible  from all other  obligations  of  Parent  and its
               affiliates.   If  any  new   service-provider  who  assumes  such
               liabilities  fails to discharge  same,  Parent and its affiliates
               shall pursue their rights against such service- provider as their
               primary  right  of  recourse  in  such  event,  but  Company  and
               Authority  shall not be relieved of their  obligations  to Parent
               and its  subsidiaries  under  this  Schedule  E with  respect  to
               liabilities not in fact discharged by such service-provider.


                                      -6-

     i.   The  obligations of Company and Authority  under this Schedule E shall
          not be limited  by, and shall  survive  the  expiration  of, any other
          contractual  relationship  between  Company or Authority and Parent or
          any of its affiliates.


II.  Employee Benefit Plans

     1.   The Employment Matters Disclosure  Schedule annexed to this Schedule E
          as  Annex  A  ("Annex  A")  lists  all  plans,   contracts  and  other
          arrangements in which Company or any Company  Subsidiary  participates
          or with respect to which Company, any Company Subsidiary, or any other
          corporation  whose  stock is being  acquired  by  Authority  under the
          Agreement or any of its Subsidiaries (collectively,  the "Employers"),
          has or may  have any  liability  or  obligation  and  which  (a) is an
          employee  benefit  plan (as  defined  in Section  3(3) of  ERISA),  or
          similar  plan  provided   with  respect  to   directors,   independent
          contractors   or   their   dependents,    (b)   provides   stock-based
          compensation,  or (c) provides any bonus,  incentive  profit  sharing,
          employee severance,  change in control, vacation, medical, sick leave,
          cafeteria,  or fringe benefit or is a deferred compensation or similar
          arrangement  (the "Employee  Plans").  True and complete copies of all
          Employee  Plans and those related  documents and records  described in
          Annex A have been made  available to Authority.  Except as required by
          the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended
          (COBRA),  or as  described  in Annex  A,  none of the  Employee  Plans
          provides  medical or life  insurance or other  welfare  benefits to or
          with respect to former  employees,  independent  contractors  or their
          dependents.  No party has failed to materially  comply with any law or
          regulation  applicable  to any Employee  Plan or with the terms of any
          Employee  Plan.  The  Employee  Plans  provide  all  compensation  and
          benefits  required  to be  provided  employees  of  Company  and their
          dependents  under  all  applicable  law.  Each of the  Employee  Plans
          intended to meet the  requirements  for  qualification  under  Section
          401(a) of the Code has been  determined by the IRS to be so qualified,
          and to the best knowledge of Company,  no circumstances exist that are
          reasonably expected by Company to result in the revocation of any such
          determination. No excise tax, or encumbrance on any of the assets with
          respect to Company has arisen or,  based on events  which have already
          occurred,  may arise with respect to any Employee Plan.  Except as set
          forth in Annex A, the transactions  contemplated by the Agreement will
          not in and of  themselves  give rise to any liability or obligation of
          Company or any other Employer, with respect to any Employee Plan. Each


                                      -7-


<PAGE>


          Employee Plan may be amended or terminated by Company or by one of the
          other  Employers  at any time on or after  the  Closing  Date  without
          violating  its terms or any law or  regulation.  Except as required by
          law,  Company has not agreed to any changes to any Employee  Plan that
          would cause an increase in benefits  under any such  Employee Plan (or
          the creation of new  benefits) or change any employee  coverage  which
          would cause an increase in the expense of  maintaining  any such plan.
          In all material  respects Company and each of the other Employers have
          made all required  contributions and paid all applicable  premiums to,
          or with  respect  to,  the  Employee  Plans as and when  due.  Neither
          Company nor any other party has made any promises or commitments  with
          respect  to  any  Employee  Plan,  other  than  in  accordance  with a
          reasonable  interpretation  of the terms of such Employee Plan. Except
          as set forth in Annex A, no suit,  action or other litigation or claim
          (excluding claims for benefits incurred in the ordinary course of plan
          activities)  has been threatened or brought against or with respect to
          any Employee Plan nor is Company  aware of any facts or  circumstances
          which might reasonably give rise thereto.

     2.   Except as set forth in Annex A, no liability  under Subtitle C or D of
          Title IV of ERISA has been or is reasonably expected to be incurred by
          Company with respect to any "single-employer plan," within the meaning
          of Section  4001(a)(15) of ERISA,  currently or formerly maintained or
          contributed to by Company ("Pension Plan") or the single-employer plan
          of any entity (an "ERISA  Affiliate")  which is or was  considered one
          employer  with the  Company  under  Section  4001 of ERISA or  Section
          414(b),  (c), (m) or (o) of the Code (an "ERISA Affiliate Plan").  The
          Pension Benefit Guaranty Corporation has not instituted proceedings to
          terminate any Pension Plan or ERISA  Affiliate  Plan, and no condition
          exists that  presents a material  risk that such  proceedings  will be
          instituted.  Company neither has nor will have any material  liability
          of any nature whatsoever  (contingent or otherwise)  arising out of or
          relating to any ERISA  Affiliate  Plan. None of the Pension Plans is a
          "multiemployer  plan"  (within  the meaning of Section  4001(a)(3)  of
          ERISA),  and neither Company nor any ERISA Affiliate  currently has an
          obligation  to  contribute  to  or  has  contributed  to  or  had  any
          obligation to contribute to a  multiemployer  plan during the six-year
          period immediately preceding the date of the Agreement. No notice of a
          "reportable  event,"  within the meaning of Section  4043 of ERISA for
          which the thirty (30)-day  reporting  requirement has not been waived,
          has been  required to be filed by Company or Parent as a result of the
          transactions  contemplated herein. No Pension Plan has an "accumulated
          funding  


                                      -8-


<PAGE>

          deficiency"  (whether or not waived) within the meaning of Section 412
          of the Code or Section 302 of ERISA and neither  Company nor any ERISA
          Affiliate has an outstanding funding waiver.  Company has not provided
          and is not required to provide, security to any Pension Plan or to any
          ERISA Affiliate Plan pursuant to Section 401(a)(29) of the Code.

     3.   All  contributions  required to be made under the terms of any Pension
          Plan have been timely made when due and have been properly reported in
          the financial statements included in the SEC Reports.

     4.   Except as  disclosed  in Annex A, under each  Pension  Plan which is a
          single-employer  plan and under each ERISA  Affiliate  Plan, as of the
          last day of the most recent plan year ended prior to the date  hereof,
          the actuarially determined present value of all "benefit liabilities",
          within the meaning of Section  4001(a)(16)  of ERISA (as determined on
          the basis of the  actuarial  assumptions  contained in the  respective
          plan's  most  recent  actuarial  valuation),  did not  exceed the then
          current  value of the  assets  of such  plan,  and  there  has been no
          material  adverse  change in the financial  condition of any such plan
          since the last day of the most  recent  plan year.  All  contributions
          with respect to each Pension Plan have been made when due.

     5.   Payments  resulting from the  transactions.  (a) The  consummation  or
          announcement of any transaction contemplated by the Agreement will not
          (either alone or upon the occurrence of any additional or further acts
          or events)  result in any (i)  payment  (whether of  severance  pay or
          otherwise)   becoming   due  from   Company  or  any  of  the  Company
          Subsidiaries  to any officer,  employee,  former  employee or director
          thereof  or  to  the  trustee  under  any  "rabbi  trust"  or  similar
          arrangement, or (ii) benefit under any Employee Plan being established
          or becoming accelerated,  vested or payable and (b) neither Company or
          any of the  Company  Subsidiaries  is a party  to (i) any  management,
          employment deferred  compensation,  severance  (including any payment,
          right or benefit  resulting from a change in control),  bonus or other
          contract for personal services with any officer, director or employee,
          (ii) any  consulting  contract  with any person who prior to  entering
          into such  contract  was a director or officer of Company or (iii) any
          plan,  agreement,  arrangement or understanding  similar to any of the
          foregoing.

     6.   Labor  Agreements.  As of the date hereof,  except as set forth in the
          Company SEC Reports filed prior to the date of the Agreement,  neither
          Company  nor  any  of  the  Company  Subsidiaries  is a  party  to any
          collective


                                      -9-


<PAGE>

          bargaining  agreement or other labor agreement with any union or labor
          organization.  To the best knowledge of Company, as of the date of the
          Agreement,  except as set forth in Annex A, there is no current  union
          representation  question involving  employees of Company or any of the
          Company  Subsidiaries,  nor  does  Company  know  of any  activity  or
          proceeding of any labor  organization (or  representative  thereof) or
          employee group to organize any such employees.  Except as disclosed in
          the Company SEC Reports filed prior to the date of the Agreement or in
          Annex  A,  (a)  there  is  no  unfair   labor   practice,   employment
          discrimination  or other material  complaint against Company or any of
          the Company Subsidiaries pending, or to the best knowledge of Company,
          threatened,  (b) there is no strike,  or lockout or material  dispute,
          slowdown  or  work  stoppage  pending,  or to the  best  knowledge  of
          Company, threatened, against or involving Company, and (c) there is no

                                   SCHEDULE F

                             Grant of Future Rights
                             ----------------------

         1.  Generating  Facility  Sites.  Effective  upon the Closing and for a
period of 99 years  thereafter,  Parent  shall (and to the extent  necessary  to
effectuate the same,  cause the Transferee  Subsidiaries  to) grant to Authority
the right (the  "Right"),  subject  to the  rights of Parent and the  Transferee
Subsidiaries  addressed in paragraph 4 herein,  to lease or purchase or to allow
its designee to lease or purchase  appropriately  sized and sited parcels at any
of the  then  existing  Generating  Facility  Sites  including  parcels  of land
included among those required to be transferred to GENCO at Closing  pursuant to
Section 2.1 of the Generation  Purchase  Right  Agreement  (and,  subject to the
provisions  of paragraph 2 herein,  to acquire  unlimited  access to  Generating
Facility Sites as well as appropriate  easements),  as reasonably  determined by
Authority's   consulting   engineer  and  confirmed  by  a  mutually   agreeable
independent  consulting  engineer for the purpose of  constructing  new electric
generating  facilities  to be  owned by  Authority  or its  designee;  provided,
however,  neither  Authority  nor its designee  shall have the right to lease or
purchase any parcels if such lease or purchase materially interferes with either
the physical operation of any Generating Facilities or the GENCO's environmental
compliance. The parties shall attempt to identify a site at a location that will
minimize any payments that may be required from Authority or its designees under
paragraph 2. Parent and the Transferee  Subsidiaries will not unreasonably limit
or restrict Authority's ability to investigate and identify such parcels.

         2. Interference Compensation.  If Authority's construction or operation
of new generating units at Generating  Facility Sites or its use of the Shoreham
Site materially  interferes with either the physical operation of the Generating
Facilities or with Parent's (or the Transferee Subsidiary's, as the case may be)
environmental compliance,  Authority shall ensure that Parent or such Transferee
Subsidiary  will be  compensated  for  the  adverse  impact  on  Parent  or such
Transferee Subsidiary of such interference.

         3. Fair  Market  Value.  The lease or  purchase  price for the  parcels
referred  to in  paragraph 1 will  include the fair market  value at the time of
lease or purchase as determined by an independent real estate appraiser  jointly
selected by the Parties. The appraisal methodology will be determined and agreed
upon by Parent and  Authority  prior to the  Closing  Date,  provided  that such
appraisal  methodology  shall  take into  account  any  decreased  value of such
parcels resulting from the requirements of paragraph 2.

         4. Right of First  Refusal.  Notwithstanding  Authority's  rights under
paragraph 1 herein,  Parent and the Transferee  Subsidiaries will have the right
to sell or lease Generating  Facility Sites, other than parcels of land included
among those


<PAGE>

required to be  transferred  to GENCO at Closing  pursuant to Section 2.1 of the
Generation  Purchase  Right  Agreement  until the  expiration of the term of the
Purchase Right (as therein  defined),  to third parties where: (i) Authority has
not already exercised its right to purchase such sites; and (ii) where such sale
or lease would not  interfere  with  Authority's  rights  under a then  existing
lease. However,  Parent's or such Transferee Subsidiary's right to sell or lease
a parcel at a Generating  Facility  Site to a third party (for  purposes of this
paragraph 4 referred to as the "property") shall be subject to Authority's right
of first refusal to purchase or lease such property as hereafter  provided.  The
terms of any such third party sale or lease shall have been negotiated by Parent
or such Transferee Subsidiary in good faith pursuant to a bonafide written offer
and shall not include terms and  conditions  that would make it  impractical  or
difficult for Authority to exercise its right of first refusal.

         (b) Parent or such Transferee Subsidiary may sell or lease the property
to a third party only after  providing  Authority  written notice (the "Transfer
Notice") of its intent to sell or lease such property. The Transfer Notice shall
include an offer to Authority to purchase or lease the property (as the case may
be) at a price equal to the Offered  Price.  For  purposes of this  paragraph 4,
"Offered  Price" shall be the price offered by the third party for the property,
and accepted by Parent or such Transferee Subsidiary,  including any non-cash or
like-kind  offer,  which  Authority  shall  have the right to match by paying an
equivalent amount in cash or bonds.

         (c) If  Authority  does not accept the offer  provided in the  Transfer
Notice at the Offered Price of the property  (for  purposes of this  paragraph 4
referred to as the "Transfer  Price") within sixty (60) days, or one hundred and
twenty (120) days if the Transfer  Price is greater than or equal to One Million
Dollars  ($1,000,000),  after  receipt of the  Transfer  Notice,  Parent or such
Transferee  Subsidiary  may proceed to sell or lease such  property to the third
party pursuant to a bonafide  written offer or agreement at a price no less than
the Transfer  Price;  provided,  however,  if such  transfer is not  consummated
within nine (9) months after  Authority's  receipt of the Transfer Notice,  that
transfer  shall again become  subject to the  provisions of this paragraph 4, to
provide a new Transfer Notice to Authority.

         5. Shoreham  Site.  Authority will acquire at the Closing Date for fair
market  value,  an  appropriately  sized  parcel,  as  reasonably  determined by
Authority's   consulting   engineer  and  confirmed  by  a  mutually   agreeable
independent  consulting engineer, at the Shoreham Site (as defined in Appendix A
attached  hereto) to serve as the  terminus  for an  undersound  cable  (nominal
rating  approximately 600 MW) and the site for up to approximately 600 MW of new
gas fired combined cycle generating  facilities and be granted  unlimited access
to the site as well as Appropriate Shoreham Easements.


                                      - 2 -


<PAGE>

"Appropriate  Shoreham  Easements"  means general  access  easements and utility
easements, as well as easements determined by LIPA or its designees to be needed
from time to time to construct, maintain and operate the facilities described in
this Section 5 and related  facilities  (the "LIPA  Facilities")  in an economic
manner, including easements for:

         o        natural gas pipelines
         o        fuel oil pipelines
         o        electric transmission facilities and rights of way
         o        electric distribution facilities and rights of way for
                  station service
         o        communication facilities
         o        construction laydown, staging and parking
         o        environmental monitoring equipment
         o        environmental buffer (which will be defined through
                  mutual agreement):

The locations of such easements to be reasonably and mutually agreed upon.

Parent or an Affiliate thereof, as the case may be, will retain all right, title
and  interest  in, to or of the  combustion  turbine  and diesel  peaking  units
located on this site, and will be granted  unlimited  access to such facilities.
Should the parties  agree that there would be  significant  economic  savings to
Authority by locating a portion of the cable terminus site or the combined cycle
generating facility site on land on the Shoreham Site beyond the fenced in area,
then Parent and/or an Affiliate thereof will sell at fair market value a portion
of the land within the Shoreham Site  Additional  Area (as defined in Appendix A
attached hereto) that is thereby required. Parent and/or such Affiliate will not
unreasonably  withhold  its or their  agreement.  Authority's  actual use of the
property  acquired  pursuant  hereto  shall not be limited to a terminus  for an
underground  cable  or a site  for a new gas  fired  combined  cycle  generating
facility,  and if so used,  such cable and  generating  facilities  shall not be
limited to 600MW.

Authority  will be  responsible  for any  and  all  transmission  reinforcements
reasonably  required to accommodate either of the foregoing,  as contemplated in
Section 4.3 of the Power Supply Agreement.

         6. Method of Exercise of the Right.  The Right may be exercised only by
giving  of  written  notice  to  Parent.  Notice  must be  accompanied  by:  (1)
certification  by the  Chairman  or  Executive  Director of  Authority  that the
exercise of the Right has been affirmatively  approved by the vote of a majority
of all members of the entire Authority Board of Trustees;  and (2) a copy of the
related resolutions of the Authority Board of Trustees  certificated as true and
correct by the Chairman or Executive Director of Authority.


                                      - 3 -


<PAGE>

         7.  Procedure.  In the case of any sale and  purchase  of any  Property
pursuant to Authority's exercise of the Right, the form and content of the legal
descriptions  thereof and conveyancing  documentation with respect thereto shall
be determined by representatives of Parent or Transferee Subsidiary, as the case
may be,  subject to the consent of the Authority,  and shall be consistent  with
the  documentation  by which title was  acquired,  local  custom with respect to
documenting transfer of property and grantor's acts.

         8.   Local   Transportation   Charge.   Effective   upon  the   Closing
interruptible  gas  transportation  to the  existing  generation  units  will be
continued on the same basis as is currently  provided.  Parent will also provide
an interruptible gas transportation  rate on the distribution system included in
the Transferred Assets and any extensions thereof to new generation  (regardless
of who owns it) above a mutually  agreeable MW threshold,  of 19 cents/dekatherm
adjusted only for any system capital  improvements  specifically  required which
will be charged on a cost-based,  return on rate base basis, using Parent's cost
of capital for its gas system.  This pricing  will be  continued  for 11.5 years
after the acquisition is completed.

         9. Business  Combinations.  Effective upon the Closing and for a period
of 99  years  thereafter,  Parent  will  not  (and to the  extent  necessary  to
effectuate the same,  prevent its  Subsidiaries  from) increase any fee, rate or
charge to the Authority on the basis of any business  combination  involving the
Parent or any of its Subsidiaries.

         10. Owernship  of/Access to Common Plant.  Parent will own common plant
(as provided in Schedules A and B) and will charge  Authority for its beneficial
use through the Management  Services  Agreement,  the Power Supply Agreement and
the Energy Management Agreement. The allocation of costs related to common plant
between gas,  generation  and  transmission  and  distribution  will be mutually
agreeable to all parties.  Such charges to Authority  will be  determined in the
same manner as common plant is charged to gas  customers  by Parent's  regulated
gas  business;  charges  to rate  payers  will not  increase  as a result of the
BUG/LILCO  merger or any future  merger or business  combination  by Parent,  or
Authority's acquisition of the Company.

         The  Authority  and Parent  will  mutually  agree upon the  appropriate
allocation  of real  property (as provided in Schedules A and B) and will select
personal  property (e.g.,  billing/customer  service hardware and software) that
Authority  shall have access to or control of as owner of the T&D System.  After
the Effective  Time and for 99 years,  Parent will give  Authority the perpetual
right to enter into leases for such  assets or  sub-contract  for such  services
which it may assign to a subsequent  management  services  contractor.  Terms of
each  such  lease  will  be fair  market  value  as  determined  by  independent
appraisers.

<PAGE>

         11. Tax Exempt  Securities.  Parent shall not, nor shall Parent  permit
any Subsidiary to take any action that would likely jeopardize the qualification
of  outstanding  revenue  bonds which  qualify on the date of the Closing  under
Section  142(a)  of  the  Code  as  "exempt  facility  bonds"  or as  tax-exempt
industrial development bonds under Section 03(b)(5) of the Internal Revenue Code
of 1954, as amended, prior to the Tax Reform Act of 1986.

         12. Access to  Properties.  Effective upon the Closing and for a period
of 99 years thereafter,  the Authority and its consultants and agents shall have
a right of unrestricted  access to the Allocated Common Facilities as more fully
described in Section 3.1(F) of the Management Services Agreement.  The Authority
and its consultants  and designees  shall have a dedicated  on-site office space
also as described more fully in Section 3.1(F).

             During the term of the Management Services Agreement, Parent, or as
appropriate,  Parent's Subsidiaries may enter upon Authority's  transmission and
distribution  system  to  perform  its  duties  thereunder,  all as  more  fully
described in Section 3.1(C) of the Management Services Agreement.

         13.  Easements.  In connection with the acquisition by Authority of any
right, title or interest to any property as contemplated herein, Authority shall
grant Parent an  irrevocable  and  perpetual  easement for the  maintenance  and
access of and to any Transferred  Assets located on or under adjoining  property
of Seller,  provided if Parent's use of such easement materially interferes with
either the physical  operation of any generating  facilities or with Authority's
environmental  compliance,  Parent shall compensate Buyer for the adverse impact
on Authority of such interference.

         14.  Customer  Billing &  Services  System.  If, at any time  after the
effective time of the Closing,  Parent shall sell, lease or otherwise market its
Customer  Billing/Customer  Services ("CBS") system, currently under development
with James Martin & Co. and others,  then Parent shall distribute 66-2/3% of its
net revenues  resulting  from such sale or marketing to Authority.  Prior to the
Closing,  expenses  and  costs  for the  development  of CBS  shall  be borne by
ratepayers to the extent  consistent with existing New York State Public Service
Commission ("NYSPSC") law and regulations.  After the Closing, such expenses and
costs shall be reflected in annual budgets to the extent agreed by Authority and
Manager.

         15. Non-Competition,  Sale to Third Parties. Effective upon the Closing
and for a period of 99 years  thereafter,  Parent  shall not (and to the  extent
necessary to effectuate the same,  shall cause its  Subsidiaries not to) compete
with  Authority,  directly  or  indirectly,  as a provider  of  transmission  or
distribution service on Long Island; provided,  however, that Parent may provide
non-retail  delivery of power on LILCO's  property to serve its existing  common
plant and generating facilities. To the


                                      - 5 -


<PAGE>

extent that Parent sells  capacity or energy in the territory  serviced by LILCO
after  the  Closing,  such  capacity  or  energy  is  to  be  delivered  through
Authority's transmission and distribution system.

             Parent further  agrees that it will not oppose any tariffs,  access
charges or fees for the use of Authority's transmission and distribution system,
whether or not such tariffs,  access  charges or fees are  established  by or on
behalf of Authority;  provided,  however,  that such tariffs,  access charges or
fees shall be non-discriminatory between Parent and other affected parties.

         16. Synergy Savings.  Parent and BUG agree that Authority will share in
the  projected   ten-year   synergy   savings   attributable  to  the  BUG/LILCO
combination.  Authority's share of synergy savings will be based upon the amount
of the projected  savings  allocated by the NYSPSC to LILCO electric rate payers
up to a maximum of 2% of LILCO's  projected  ten-year  average  annual  electric
revenues.  Eight/tenths of the aggregate projected ten-year savings so allocated
by the  NYSPSC  will be used to  reduce  the  budgeted  cost  amounts  under the
Management  Services  Agreement,  the  Power  Supply  Agreement  and the  Energy
Management  Agreement,  as appropriate,  in the following percentages in each of
the first eight years.

         Year                       Percentage

         1                            2.44%
         2                            7.20
         3                            9.68
         4                           12.18
         5                           14.64
         6                           16.93
         7                           18.08
         8                           18.85
                                    ------
                                    100.00%

Based  upon the  anticipated  synergy  savings  announced  by LILCO  and BUG and
assuming  allocation by the NYSPSC of such savings to LILCO electric  ratepayers
equal to 2% of LILCO's average annual electric  revenues,  the Authority's share
of the synergy  savings  pursuant to the schedule above will result in aggregate
net  savings  (including  consideration  of carrying  costs) to the  Authority's
electric ratepayers of approximately $413 million over the eight years following
the closing.

         17. NOx and SOx Emission  Credits.  Parent shall apply all NOx, SOx and
other  air  emission  credits  owned  by the  Transferee  Subsidiaries  for  the
continued  operation  of the  Generating  Facilities  at cost,  if any,  without
markup. Effective as of the Closing Date, 67% of the net proceeds of any sale or
other  disposition  of  emission  credits  which are  excess to the needs of the
operation of the Generating  Facilities  shall be credited to the annual charges
to the Authority under the Agreements and the


                                      - 6 -


<PAGE>

balance  shall be for Parent's  account.  Parent shall  provide  Authority  with
notice of its  intention  to sell or  otherwise  dispose of emission  credits in
order to allow Authority  sufficient time to submit a bid for such credits if it
so chooses.

         18. Omnipoint.  Effective as of the Closing Date,  66-2/3% of all lease
rentals and attachment  fees received by Company after the Closing Date from the
Omnipoint  agreements,  the  MCI  metro  agreements  and  from  other  similarly
structured and financed telecommunications  agreements entered into prior to the
Effective  Time  will be  payable  to  Authority  and the  balance  shall be for
Parent's account. In addition, to the extent that less than 66- 2/3% of all such
lease rentals and attachment  fees received by Company prior to the Closing Date
were allocated or credited by Company to electric ratepayers,  Company shall pay
to  Authority  the  difference  between  66-2/3% of such  amounts and the amount
allocated or credited to electric ratepayers.

         19. Tax Cases.  Parent and the Transferee  Subsidiaries shall not, from
and after the Closing Date,  commence or prosecute any tax case  challenging any
property tax relating to the Generating Facilities, except for claims in respect
of assessments (other than generally applicable  assessments and other than when
such  assessment  is in  conjunction  with a  property  addition),  which may be
pursued  fully by  Parent,  including,  without  limitation,  any  property  tax
assessment on the Generating  Facilities or Generating  Facility Sites, but only
if the  assessment  on any such  challenged  facilities  is increased  not in an
appropriate  proportion  to the  increase  in value  related to taxable  capital
additions  affixed to the tax parcel  between the last two tax status dates.  If
the  tax  attributable  to  the  assessment  on  the  Generating  Facilities  or
Generating  Facility Sites is not included in the costs paid by Authority or its
Affiliates (e.g., gas facility located on Generating  Facility Site) then Parent
or the Transferee Subsidiaries,  in its or their sole discretion, may pursue tax
challenges on such assessments. This provision shall expire upon the termination
of the Power Supply Agreement.

In the event the Parent or Transferee Subsidiaries challenge any tax assessments
on the  Generating  Facilities,  any tax  refunds  received  by  Parent  or such
Transferee  Subsidiary shall be shared 25%/75% between Parent or such Transferee
Subsidiary and Authority,  respectively.  Parent or the Transferee  Subsidiaries
shall be responsible for all preparatory  efforts and litigation-  related costs
pertaining  to  any  such  challenge.  This  provision  shall  expire  upon  the
termination of the Power Supply  Agreement,  except that Authority will continue
to share 75% of tax refunds  received after such  termination to the extent that
such refunds relate to property taxes for which Authority has reimbursed  Parent
or the Transferee Subsidiaries.

                                 RETAINED ASSETS

                  "Retained Assets" means all properties or assets  contemplated
hereby to be owned at the  Effective  Time (x) by Company or (y) by any  Company
Subsidiary  or Company  Joint Venture not  constituting  a Transferred  Asset as
determined pursuant to Schedule A or Schedule B, including, without limitation:

               (A)  Electric   transmission   and   distribution   system  ("T&D
                    System").  "T&D System" means the  electricity  transmission
                    and  distribution  system owned by Company at the  Effective
                    Time,  as  described  in the  paragraph  below,  and assets,
                    facilities, equipment or contractual arrangements of Company
                    used to provide the  transmission  and  distribution  of the
                    electrical  energy and  capacity  available  from the System
                    Power  Supply (as  defined in  Appendix 1 to the  Management
                    Services  Agreement)  to the  counties of Suffolk and Nassau
                    and that  portion of the County of Queens  constituting  the
                    Company's  service area as of the effective date of the Long
                    Island Power Authority Act, N.Y. Pub. Auth.  Lawss.  1020 et

         THIS  MANAGEMENT  SERVICES  AGREEMENT  is made and dated as of June 26,
1997  between  the  Long  Island   Power   Authority,   a  corporate   municipal

                                    RECITALS

         WHEREAS,  an affiliate of the Authority is expected to become the owner

for the operation and  maintenance of the T&D System and for the  performance of
the  Construction  Work (as  defined  herein)  relating  to the T&D System to be
undertaken in accordance  with the terms hereof in order to assure the continued
delivery of electric energy to the customers of the T&D System.

         WHEREAS,  as  an  essential  term  and  condition  of  the  Acquisition
Agreement, the Authority has agreed to contract with the Manager for the purpose
of  providing,  and the  Manager  has  agreed  to  provide,  the  Operation  and
Maintenance Services (as herein defined) and the Construction Work in accordance
with the terms hereof and in a manner  consistent  with policies  established by
the Authority.

         WHEREAS,  in  accordance  with the terms  hereof,  the  Authority is to
establish the System  Policies and Procedures for the T&D System and the Manager
is responsible for the implementation of those policies.

         It is, therefore, agreed as follows:

shall be charged to the  Authority at the cost  Manager paid for such  inventory
(excluding  any  inter-company  profit).  The Manager shall maintain and, at the
Authority's request,  provide Cost Substantiation for all such costs invoiced to

additional  work or costs  incurred  for  which  the  Authority  is  responsible
hereunder.

the parties  shall:  (1) promptly  meet and negotiate in good faith a substitute
for such clause,  provision,  section or Article  which  shall,  to the greatest
extent legally  permissible,  effect the intent of the parties  therein;  (2) if
necessary or desirable to accomplish item (1) above, apply to the court or other
authority,  as  applicable,  having  declared  such  invalidity  for a  judicial
construction of the invalidated portion of this Agreement;  and (3) negotiate in

provisions  of  this  Agreement  as  may  be  necessary  in  addition  to and in
conjunction  with items (1) and (2) above to effect  the  intent of the  parties
reflected in the invalid  provision.  The invalidity of such clause,  provision,
subsection,  Section or Article shall not affect any of the remaining provisions
hereof,  and this  Agreement  shall be construed and enforced as if such invalid
portion did not exist.

         (D) No Litigation. There is no action, suit or other proceeding, at law
or in equity, before or by any court or governmental  authority,  pending or, to

adversely affect the validity or  enforceability  of this Agreement or any other
agreement  or  instrument  entered  into by the Manager in  connection  with the
transactions contemplated hereby, or which would materially and adversely affect
the  performance by the Manager of its  obligations  hereunder or by the Manager

the T&D System;  (2) the Manager is familiar with local  conditions which may be
material to the Manager's  performance of its obligations  under this Agreement;
and (3) based on the  foregoing,  the T&D System is acceptable  and suitable for
the  performance  of the  Manager's  obligations  hereunder  and will permit the
Manager to safely and reliably operate and maintain the T&D System in compliance
with the terms and conditions of this Agreement.  In making such acknowledgment,

                                   ARTICLE III

              OWNERSHIP OF THE TRANSMISSION AND DISTRIBUTION SYSTEM

         SECTION 3.1. OWNERSHIP OF THE T&D SYSTEM. (A) Authority Ownership.  The
T&D  System is and shall be owned by the  Authority  (or a  subsidiary  thereof)
throughout  the Term of this  Agreement.  The Manager  shall not have any legal,
equitable,  tax,  beneficial or other ownership or leasehold interest in the T&D
System.

         (B) Engagement of Manager.  The Authority hereby engages the Manager as
an independent contractor to furnish the services described in this Agreement at
and for the compensation provided for hereunder. The Manager hereby accepts such
engagement upon the terms and conditions provided for herein.

operate the T&D System to perform the Operation and Maintenance  Services and/or
manage Construction Work for the Authority,  all in accordance herewith, and for
no other purpose unless otherwise directed or approved by the Authority.

         (D) Encumbrances.  The Manager shall not, without the Authority's prior
written  consent,  directly or indirectly,  create or permit to be created or to
remain, and will promptly discharge,  at its expense, any Encumbrance on the T&D
System,  other than (1) Encumbrances  existing as of the date hereof, or (2) any
Lien affecting the T&D System (i) resulting solely from any action or failure to
act by the  Authority  or anyone  claiming  by,  through or under the  Authority
(other than the Manager and persons  claiming by, through or under the Manager);
or (ii) created by Subcontractors that are promptly discharged or bonded against
by the Manager.  Nothing in this Agreement shall be deemed to create any Lien or
Encumbrance in favor of the Manager on any asset of the Authority, including the
T&D System, as security for the obligations of the Authority hereunder.

         (E)  Surrender of the T&D System.  At the end of the Term  hereof,  the
Manager shall peaceably leave and surrender the T&D System to the Authority in a
condition consistent with the Manager's  construction,  operation,  maintenance,
repair and  replacement  responsibilities  hereunder.  In conjunction  with such
surrender,  the Exit Test shall be  conducted  in  accordance  with  Section 8.3
hereof.

         (F)  Right of  Access.  Notwithstanding  any  other  provision  of this
Agreement, beginning on the Closing Date, the Authority, as the owner of the T&D
System,  shall have a right of unrestricted access to the T&D System for itself,
its  consultants  and  agents at such  times and for such  purposes  as it deems
necessary  or  desirable.  In  addition,  the  Authority  shall  have a right of
reasonable access to the T&D System for other visitors upon reasonable notice to
the Manager.  The  Authority  and its  consultants  and agents also shall have a
right of unrestricted  access to the Allocated Common  Facilities  during normal
business hours and, with  reasonable  notice,  outside of normal business hours.
When,  as  reasonably  determined  by the  Authority to be necessary  due to the
nature of the task performed,  access to the Common  Facilities shall be allowed
to the  Authority and its  consultants  and agents on an  unannounced  basis for
audit  and  oversight  purposes.   All  Authority  personnel,   representatives,
designees  and other  visitors  shall comply with the Manager's  on-site  safety
policies and  procedures.  The Authority and its consultants and designees shall
have a dedicated on-site office space located at the current LILCO  headquarters
building or another suitable site mutually agreed upon and a separate work space
adequate  to  enable  the  Authority  to  exercise  its  oversight   rights  and
responsibilities under this Agreement. Such work space initially shall include a
separate  lockable  room or rooms large enough for six people and shall  provide
space sufficient for computer terminals, a printer,  telephones,  a fax machine,
lockable  file cabinets and desks and other office  equipment and supplies.  The
file cabinets and desks shall be able to

commonly used supplies and facilities located on-site. In addition,  the Manager
shall make  available  such  additional  or different  office and work space and
equipment  and supplies as reasonably  requested by the  Authority  from time to
time.

Date,  who shall have at least ten (10)  years  experience  with  respect to the
management of the T&D System, a similar system or an electric utility generally,
and who shall be responsible for the day to day operation and maintenance of the
T&D System. The Manager shall inform the Authority of the identity of the person
serving from time to time as T&D System  Supervisor,  and of the  telephone  and
beeper  numbers or other means by which such person and his or her  designee may
be contacted at all times. The Manager and the Guarantor shall appoint officials
with senior supervisory  responsibility for the operation of the T&D System (the
"Senior  Executives") and shall inform the Authority of the telephone and beeper
numbers or other  means by which such  persons  may be  contacted  at all times.
Recognizing the need for an amicable working  relationship between the Authority

conditions of this Agreement and any other changes in circumstances  and deliver
to the Authority six (6) copies of an updated  Operation and Maintenance  Manual
no later than 60 days prior to the Closing  Date.  The Manager  shall review and
discuss in good faith with the  Authority any aspect of the existing and updated
Operation  and  Maintenance  Manual.  The content of the updated  Operation  and
Maintenance  Manual shall be  consistent  with the terms and  provisions of this
Agreement, shall provide for the operation and maintenance of the T&D System and
the training of employees in accordance with the Contract  Standards,  and shall
otherwise be  sufficiently  detailed to permit the T&D System to be operated and
maintained by a third party reasonably  experienced in electricity  transmission
and  distribution  operations.  Neither the review of or comment  upon,  nor the
failure of the Authority to comment upon, the Operation and  Maintenance  Manual
shall relieve the Manager of any of its  responsibilities  under this Agreement,
be deemed to constitute a representation by the Authority that operating the T&D
System  pursuant  to the  Operation  and  Maintenance  Manual will cause the T&D
System to be in compliance  with this Agreement and the Contract  Standards,  or
impose  any  liability  upon the  Authority  except  as  expressly  provided  in
subsection 4.2(E) hereof.  During the Term, the Manager shall remain responsible
for the  Operation  and  Maintenance  Manual and shall keep it current by making
necessary  updates,  supplements  or  revisions  thereto to reflect the Contract
Standards.  Manager shall  promptly  supply the Authority with six (6) copies of
any such updates, supplements or revisions thereto.


                                       12


<PAGE>

The  Authority  shall have the right to review and comment on any such  updates,
supplements  or  revisions  prior  to  their  inclusion  in  the  Operation  and
Maintenance  Manual.  Upon the  commencement of procurements for future contract
bids for the management of the T&D System, the Operation and Maintenance Manual,
with the  exception  of that  information  that the  parties  mutually  agree in
writing is proprietary,  shall be available to any qualified prospective bidder.
The Authority  shall  require such  qualified  prospective  bidders to treat the
Operation and Maintenance Manual confidentially.

         (E)  Delivery  of  Manual  on  Termination.   Upon  the  expiration  or
termination  of this  Agreement  for any reason  whatsoever,  the Manager  shall
deliver  to the  Authority  the  Operation  and  Maintenance  Manual  for use in
connection  with the  operation  and  maintenance  of the T&D System.  Any final
payments  due  at the  time  of  the  termination  of  the  Agreement  shall  be
conditional upon delivery of such Operation and Maintenance  Manual. Such manual
will be available for use by any subsequent  manager,  provided any such manager
is required by the Authority to also maintain the confidentiality of information
contained  therein and is prohibited from using any such information  other than
in connection  with the  management of the T&D System.  The Authority  will hold
Manager  harmless from any Loss and Expense solely  resulting from any claims or
Legal  Proceedings  commenced  by third  parties  based  upon use by  subsequent
managers of such manuals.

         SECTION 4.3.  MAINTENANCE  AND REPAIR OF T&D SYSTEM.  (A) General.  The
Manager  shall  maintain  the T&D  System,  the T&D  System  Site and the Common
Facilities in good working order and repair and in a neat and orderly  condition
(including  the  cleanup of litter and debris as  required),  and shall  conduct
periodic,  corrective,  and preventive  maintenance and repair of the T&D System
consistent  with the Contract  Standards for the purpose of, among other things,
mitigating and preventing  abnormal wear, tear and usage. The Manager shall also
maintain a spare parts inventory as required under the Contract  Standards.  The
Manager  shall  maintain  the  aesthetic  quality  of the T&D System and the T&D
System Site; provided,  however, that such maintenance  responsibility shall not
materially  adversely affect the reliability of the T&D System.  As used herein,
"maintenance"  means those  routine  and/or  repetitive  activities  required or
reasonably  recommended  by  the  equipment  or  facility  manufacturer,  by the
Authority or by Manager,  or customary in the industry to provide for the normal
useful life of  property,  plant,  equipment  or other  capital  items.  As used
herein, "repair" means those non-routine/non-repetitive  activities required for
operational  continuity,  safety and performance  generally due to failure or to
avert a failure  of the T&D  System  or any of its  components.  If the  Manager
chooses  to defer  any  scheduled  maintenance  or  repair  provided  for in any
maintenance or repair program or in the Annual T&D Budget that is in excess of a
per item or category  dollar  amount or a dollar  amount on a cumulative  basis,
such dollar amount to be agreed upon by the parties prior to the adoption of the
initial  Annual T&D Budget or for more than a number of months to be agreed upon
by the  parties  prior to the  adoption of the  initial  Annual T&D Budget,  the
Manager  shall so advise the Authority  and provide  satisfactory  justification
therefor,  provided that the Manager may not defer any maintenance or repairs if
such deferral could  reasonably be expected to materially  and adversely  affect
the reliability or safety of the T&D System.

         (B) Maintenance  Expenditures.  The Manager shall be authorized to make
expenditures for routine repair, maintenance, or replacement as set forth in the
Annual T&D Budget.  The  Authority  may  require  that the Annual T&D Budget set
forth,  on a project or category basis,  anticipated  repairs,  maintenance,  or
replacement  in excess of a dollar amount to be agreed upon by the parties prior
to the  adoption of the initial  Annual T&D Budget.  The Manager  shall  provide
proposals to, and obtain prior  written  authorization  from,  the Authority for
routine repair, maintenance, or replacement projects or categories not set forth
in the Annual T&D Budget if the projected cost therefor is reasonably  estimated
to exceed a dollar limit for such  projects or  categories  to be agreed upon by
the parties  prior to the adoption of the initial  Annual T&D Budget;  provided,
however, the Manager shall


                                       13


<PAGE>

respond  immediately to any emergency  situations and shall notify the Authority
immediately upon initiating such emergency response.

         (C)  Ownership of T&D System  Assets.  All  additions to the T&D System
purchased in  conjunction  or for the use with any part of the T&D System during
the Term shall be the property of the  Authority,  except those which are leased
or constitute part of the Common Facilities. Manager shall maintain, and provide
to the Authority, perpetual records of all capital items purchased, installed or
constructed (including,  without limitation,  vehicles,  fixtures and equipment)
with the Authority's funds.

         (D) Retirement of T&D System Assets.  In the event the Manager  intends
to retire from service T&D System  assets  constituting  a "unit of property" as
set forth in the  Authority's  capital  asset  policies with an original cost at
least equal to a dollar  amount that will be agreed upon by the parties prior to
the  adoption of the initial  Annual T&D Budget,  the Manager  shall  notify the
Authority either in the proposed Annual T&D Budget, or, if the Annual T&D Budget
has been adopted for the applicable Contract Year, at least 90 days prior to the
scheduled  retirement  date.  The Manager may not retire such T&D System  assets
without the prior  written  approval of the  Authority.  Any salvage or residual
value of any T&D System  assets shall be for the account of the  Authority.  All
retirements shall be conducted in accordance with the Bond Resolution.

         (E)  Insurance and Other Third Party  Payments.  To the extent that any
repair or  replacement  costs that are incurred  pursuant to this Article can be
recovered by the Manager from any insurer  providing  the Required  Construction
Work Insurance or the Required Operating Period Insurance, or from another third
party,  the Manager shall exercise with due diligence such rights as it may have
to effect such  recovery.  The Manager shall give prompt  written  notice to the
Authority  of the  receipt  of any  such  recovery  which  shall be  applied  as
appropriate to the restoration or reconstruction of the T&D System in accordance
with the Bond Resolution. The Manager shall provide the Authority with copies of
all  documentation,  and shall afford the Authority a reasonable  opportunity to
participate in and, if the Authority so determines,  to direct all  conferences,
negotiations and litigation,  regarding insurance claims which materially affect
the  Authority's  interest  under  this  Agreement.   All  applicable  insurance
recoveries   shall  be  applied  to  reducing   the  cost  of   restoration   or
reconstruction.

         SECTION 4.4.  PERFORMANCE  GUARANTEES.  (A)  Compliance  and  Remedies.
Commencing on the Closing  Date,  the Manager shall at all times comply with the
Performance   Guarantees,   except  to  the  extent  excused  by  Uncontrollable
Circumstances  or  Authority  Fault.  If the  Manager  fails to comply  with any
Performance  Guarantee,  the  Manager  shall,  without  relief  under  any other
Performance Guarantee under this Agreement, (1) promptly notify the Authority of
any such  noncompliance,  (2) promptly  provide the Authority with copies of any
notices  sent to or  received  from  any  Governmental  Body  having  regulatory
jurisdiction with respect to any violations of Applicable Law, (3) promptly make
any applicable  payments  provided for herein,  and to the extent required under
Section 6.10 hereof, any other resulting damages,  fines,  levies,  assessments,
impositions,  penalties or other charges resulting therefrom, and (4) at its own
cost and expense to the extent required under Section 6.10 hereof, promptly take
any action (including  without  limitation making all repairs,  replacements and
operating changes) necessary in order to comply with such Performance Guarantee,
continue or resume  performance  hereunder and eliminate the cause of, and avoid
or prevent recurrence of noncompliance with such Performance Guarantee.

         (B) Conditions to Performance  Guarantee  Relief.  The Manager shall be
relieved of its obligation to comply with a Performance  Guarantee to the extent
and for any period  during which the  operation of the T&D System is affected by
the occurrence of an Uncontrollable  Circumstance or Authority Fault. Should any
such  circumstances  occur, the Manager shall nonetheless (1) in accordance with
the Contract Standards,  use its best efforts to mitigate any noncompliance with
such Performance


                                       14


<PAGE>

Guarantee and restore T&D System  performance  to comply with this  Agreement as
rapidly  as   practicable,   and  (2)  promptly  advise  the  Authority  of  the
circumstances and the Manager's planned course of action.

         (r) the  right to  establish  policies  for the T&D  System  generally,
including, without limitation, policies governing wholesale or retail access;

interest in Nine Mile Point 2.

         In the event that any  obligation of Manager  hereunder  conflicts with
Applicable  Law,  Applicable  Law shall  govern  with  respect to the  Manager's
performance required hereunder.

         (B) T&D System  Policies  and  Procedures.  Not later than  thirty days
prior to the date on which  the  Manager  is  required  to submit  the  proposed
initial Annual T&D Budget,  the Authority will  establish  initial  policies and
procedures for the operation and maintenance of the T&D System,  which will take
into consideration, but not be bound by, policies and procedures in effect prior
to the  Closing  Date.  Authority  shall  promptly  notify  the  Manager  of any
subsequent changes to the System Policies and Procedures. Appendix 14 provides a
preliminary  outline  of the  topics  for which the  Authority  will  adopt such
policies and procedures.

         (C) T&D System Access  Policies and Prices.  The  Authority  intends to
establish  non-discriminatory prices and policies for access to, and use of, its
transmission facilities for its customers,  Manager or its Affiliates, and other

customers or classes of customers.

<PAGE>

Authority has authorized such  representative to act. The Authority shall advise
the  Manager as to the scope of such  authorization.  In all such  matters,  the
Authority  shall be bound,  to the extent  permitted by  Applicable  Law, by the
written communications, directions, requests and decisions made by the Authority
Representative.  The Authority  shall promptly  notify the Manager in writing of
the selection of the Authority Representative and any subsequent replacement(s).

         (E) No Acceptance,  Waiver or Release. No exercise of rights or failure
to  exercise  rights  by the  Authority  hereunder  shall  be  construed  as the
Authority's  acceptance  of any  Operation  and  Maintenance  Service  which  is
defective,  incomplete,  or otherwise not in compliance with this Agreement,  as
the Authority's release of the Manager from any obligation under this Agreement,
as an estoppel  against the Authority,  or as the Authority's  acceptance of any
claim by the Manager.  Notwithstanding  any review or approval of the  Authority
hereunder,  in no event shall the Manager be excused from the performance of its
responsibilities hereunder, except to the extent due to Authority Fault, subject
to Section 6.5, or Uncontrollable Circumstances, subject to Section 9.2.

in the  performance of their work under this  Agreement.  The Manager shall give
due  consideration  to  any  comments  of  the  Authority  with  respect  to the
performance of specific  employees.  At all times, the Manager shall comply with
Prudent  Utility  Practice  and  Applicable  Law with  respect to the  Manager's
employees and with respect to the Manager's  obligations  under this  Agreement,
including,  but not limited to, ERISA, wage withholding,  social security, equal
employment  opportunity,   age  and  disability   discrimination,   unemployment
insurance, hours of labor, wages, working conditions,  OSHA, immigration control
and other  employer-employee  related subjects. The Manager shall provide to the
Authority  copies  of the  Manager's  salary  administration  plan  and  the job
descriptions  for each of the Manager's  employees on the Closing Date and shall
thereafter provide copies of all subsequent  amendments and changes thereto. The
Manager  recognizes  that a  substantial  portion  of the work  force at the T&D
System is currently  unionized and agrees to honor existing labor  contracts and
will not rely upon mandatory  lay-offs to achieve any operational  efficiencies.
The Manager shall require that Subcontractors agree to pay prevailing wage rates
and employee  benefits in connection  with the  performance of the Operation and
Maintenance  Services and Construction Work that is performed by a Subcontractor
(other than  pursuant to existing  Subcontractor  arrangements  and renewals and
replacements  thereof)  which  would  otherwise  have  been  performed  by union
employees of the Manager.

         SECTION 4.7. SAFETY.  The Manager shall maintain a safe T&D System at a
level at least  consistent  with the Contract  Standards.  Without  limiting the
foregoing, the Manager shall: (1) take all reasonable precautions for the safety

and the  coordination  of such  activities  as shall be necessary  with federal,
State and local officials.

         SECTION  4.8.  VEHICLES  AND  EQUIPMENT.   (A)  Vehicle  and  Equipment
Identification.  The Manager's  name,  and vehicle or equipment  number shall be
visibly  displayed on both sides of its vehicles or other  equipment used by the
Manager in the operation and  maintenance  of the T&D System.  All such vehicles
and equipment  owned by the Authority and used by the Manager shall also display
the name of the Authority as owner and identify the Manager as the operator. The
size and  placement  of such  identifying  information  shall be approved by the
Authority.  No other signs or markings  shall be placed in the vehicles or other

except signs or markings  relative to use of such  equipment  including  traffic
safety signs or other safety markings.

         (B) Vehicle  Specifications,  Maintenance and Appearance.  All vehicles
used by the Manager in providing the Operation  and  Maintenance  Services or in

account  inquiry work;  customer  assistance,  credit and  collection  services;
cashiering; account connection and disconnection; and conservation advice.

         (B) Billing Services.  The Manager shall,  unless otherwise directed by
the Authority, read the meters of electric commercial,  industrial,  residential
heating and  residential  multiple rate period  customers on a monthly basis and
all  other  electric  customer  meters on a  bi-monthly  basis.  Manager  shall,
according  to the  schedule of rates,  tariffs and  policies  (the  "Schedule of
Rates") then in effect,  render bills to all T&D System customers in the name of
the Authority for electric  service  delivered on behalf of the Authority and in
the format determined by the Authority. To the extent directed by the Authority,
such bills shall also reflect electric services provided to T&D System customers
by other parties.  The Authority may implement  changes to such rates,  rules of
service,  regulations and procedures by giving written notice to the Manager not
later than sixty (60) days  prior to the  effective  date of such  change to the
extent practicable given the nature of the change.

         (C) Account  Records.  The Manager shall  maintain  customer  bills and
records as the  Authority  reasonably  requests  setting  forth in accurate  and
reasonable detail the actual and estimated meter readings, billing determinants,
charges made to the  Authority's  customers in  accordance  with the Schedule of
Rates,  and  payments  received  from each of the  Authority's  customers.  At a
minimum,  the Manager  shall  maintain the records in a manner such that data by
various customer classifications can readily be reported on a monthly basis, for
the fiscal year to date and for the most recent twelve-month period. The Manager
shall  retain any  records  that it is  required  to  maintain  pursuant to this
subparagraph  for the  term of this  Agreement  and  shall  deliver  them to the
Authority upon the Authority's request.

         (D) Collection of Monies. The Manager shall use best efforts to collect
on a timely  basis (1) all amounts  due the  Authority  for service  provided to
customers,  and for other services, in accordance with the Schedule of Rates for
the periods in which  services were  provided,  and (2) other monies owed to the
Authority  pursuant  to the  operation  of the T&D  System.  At the  Authority's
direction,  the Manager shall  investigate and implement  checking account debit
payment procedures for payment of customer bills. The Manager's responsibilities
shall also include,  consistent  with the System  Policies and  Procedures,  the
institution of legal  proceedings  in the  Authority's  name to collect  utility
billings  and other  monies owed the  Authority  related to the T&D System.  The
Manager shall provide current billing  information  concerning  customers of the
T&D System to the Authority monthly in such


                                       18


<PAGE>

form as reasonably requested by the Authority and historical billing information
as otherwise reasonably requested by the Authority.  All monies collected by the
Manager or its  Subcontractors  shall be the property of the Authority and shall
be  deposited  by the Manager  daily in the account of the  Authority  specified
pursuant  to Section  4.16.  In  collecting  such  monies,  the  Manager and any
Subcontractor  shall act solely as an agent for the  Authority and shall have no
right or claim to such  moneys  and,  without  limiting  the  generality  of the
foregoing,  shall  have no right  to  assert  a claim  of  set-off,  recoupment,
abatement,  counterclaim  or deduction  for any amounts which may be owed to the
Manager hereunder or with respect to any other matter in dispute hereunder.  The
Manager is unconditionally  and absolutely  obligated to pay or deposit all such
monies as directed by the Authority.

         It is expected that in accordance with current practice,  gas customers
of Manager's Affiliate and the T&D System electric customers will be billed in a
single statement.  In the event any electric customer who is also a gas customer
shall pay less than all of the amount due at any time under a single  statement,
the amounts collected shall be applied pro rata between the amounts owed by such
customer with respect to electric service and gas service.  To the extent moneys
are collected  for any power supply  services  provided by any unrelated  party,
amounts  collected  shall be allocated in accordance  with the directions of the
Authority.  Manager may elect to bill gas  customers  separately  provided  that
Manager shall bear all incremental costs arising by reason of any such election.

         (E) Customer Service Office  Facilities.  The Manager shall maintain at
all times during the Term hereof customer  service and/or payment offices within
Nassau  and  Suffolk   Counties  and  in  Far  Rockaway  with  specific  minimum
requirements  to be agreed upon by the parties.  The Manager  shall  establish a
local  toll  free  customer  service  number  that  shall be  identified  on all
publications, bills and correspondence.

         (F) Customer Service Office Hours.  Except as otherwise approved by the
Authority,  the Manager's  customer service office hours shall be, at a minimum,
from 8:30 a.m. to 5 p.m. daily, except Saturdays, Sundays and holidays.

         (G)  Availability of  Representatives.  Representatives  of the Manager
shall be available  during  normal  business  hours for  communication  with the
Authority or the public.

         (H) Emergency  Telephone Number. The Manager shall maintain a toll-free
emergency  telephone  number(s) for use during other than normal business hours.
The Manager shall have a representative, or an answering service to contact such
representative,  available at the  emergency  telephone  number during all hours
other than normal office hours.

         (I) New  Connections.  Manager  shall  provide new customer  connection
services, which may include electric facility design, estimation of construction
costs, new service hook-up, credit check and job scheduling.

         (J) Customer  Retention  and  Expansion  Activities.  The Manager shall
undertake,  subject to  Authority  approval,  marketing  and public  information
activities  to retain and expand the  customer  base served by the T&D System in
accordance with the System Policies and Procedures. In its sole discretion,  the
Authority may undertake its own marketing and public  information  activities or
retain  other  parties to do so. In such  event,  the Annual T&D Budget  will be
appropriately modified.

         SECTION 4.10.  SERVICE  COMPLAINTS AND DEFICIENCIES.  (A) Complaints to
Manager.  The Manager shall maintain during office hours a complaint service and
a telephone  answering system having an answering  capacity  consistent with the
System Policies and Procedures.  All service  complaints and billing  complaints
will be directed to the Manager. Copies of all complaints shall be


                                       19


<PAGE>

given to the Authority  upon request.  The Manager shall record all  complaints,
including date and time,  complainant name and address,  and nature and date and
time of  resolution  of  complaint,  in a log.  This log shall be available  for
inspection by the Authority  during the Manager's  regular office hours.  Copies
thereof shall be furnished to the Authority upon request. The Manager shall also
provide  the  Authority  with a monthly  report  summarizing  the  status of any
complaints  in such  month.  In  particular,  such  summary  shall  specify  any
complaints  for which dollar  damages in excess of a dollar  amount to be agreed
upon by the parties prior to the adoption of the initial  Annual T&D Budget have
been  asserted.  The  Manager  shall  take  such  reasonable  actions  as may be
warranted in response to customer  complaints  to retain  customers  and provide
service in accordance  with Prudent  Utility  Practice,  the System Policies and
Procedures and Applicable Law.

         SECTION 4.11. COMPLIANCE WITH APPLICABLE LAW. The Manager shall operate
and  maintain  the T&D  System  and  otherwise  perform  all of its  obligations
hereunder in accordance with Applicable Law. In the event that the Manager fails
at any time to comply with  Applicable  Law, then the Manager shall  immediately
remedy such failure and, to the extent required by Section 6.10 hereof, do so at
its cost and expense and bear all  Loss-and-Expense  of either  party  resulting
therefrom subject,  however,  to the provisions hereof regarding  Uncontrollable
Circumstances or Authority Fault and Section 6.10 hereof. Any such damage, fine,
assessment  or other charge paid by the Manager due to a violation of Applicable
Law caused by Uncontrollable Circumstances or Authority Fault or with respect to
which Manager is not  responsible  under Section 6.10 hereof shall be reimbursed
to the Manager. Notwithstanding whether a regulatory enforcement action has been
undertaken by a Governmental Body, the Authority shall have an independent right
to  require  Manager  to  comply  with all  applicable  Legal  Entitlements  and
Applicable Law.

         SECTION  4.12.  LICENSES,  PERMITS AND  APPROVALS.  The  Manager  shall
identify for the  Authority,  prepare,  and with  Authority  approval,  make and
prosecute all filings, applications and reports necessary to obtain and maintain
all permits,  licenses and approvals required to be made, obtained or maintained
by each under  Applicable  Law in order to  operate  the T&D  System.  Draft and
record copies of all such documents shall be timely given to the Authority.  The
Manager shall supply all data and  information in a timely manner,  which may be
required and which is in the Manager's knowledge or control,  and shall take all
other  action  necessary  or  desirable  in order to  assist  the  Authority  in
obtaining, maintaining,  renewing, extending and complying with the terms of all
permits,  licenses and  approvals  necessary  subsequent  to the Closing Date in
order to perform the Operation  and  Maintenance  Services and any  Construction
Work. The data and information  supplied by the Manager to the Authority and all
regulatory agencies in connection therewith shall be correct and complete in all
material  respects,  and to the extent  required  under  Section 6.10 hereof the
Manager shall be responsible  for any schedule and cost  consequences  which may
result from the  submission of materially  incorrect or incomplete  information.
Except as directed by the  Authority,  the Manager  shall not submit any data or
information  directly to the regulatory  agencies unless required to do so under
Applicable Law or by the terms of an existing license,  permit or approval.  The
Manager shall report  immediately  to the Authority all  violations of the terms
and conditions of any permit, license,  approval or Applicable Law pertaining to
the T&D System.

         SECTION 4.13.  OPERATING PERIOD INSURANCE.  Commencing with the Closing
Date and continuing throughout the remainder of the Term of this Agreement,  the
Manager shall obtain and maintain,  the Required  Operating  Period Insurance as
specified  in Appendix 4 hereto and shall comply with all  applicable  Insurance
Requirements.  The Manager shall name the Authority, its trustees,  officers and
employees as  additional  insureds or named  insureds,  as  appropriate,  on its
insurance policies, which policies shall require 30 days prior written notice to
the Authority prior to any change in or cancellation of such policies. Insurance
coverage  required  pursuant to this Section shall be maintained  with generally
recognized  financially   responsible  insurers  reasonably  acceptable  to  the
Authority and


                                       20


<PAGE>

qualified and authorized to insure risks in the State.  The cost of the Required
Operating   Period   Insurance  shall  be  paid  by  the  Manager,   subject  to
reimbursement  by the Authority  pursuant to Section 6.1 hereof as a Third Party
Cost. The Manager shall  demonstrate to the Authority,  by a bidding  process or
other acceptable  methods,  that the premiums payable for the Required Operating
Period  Insurance  constitute  a fair  and  reasonable  price  for the  coverage
provided.  The  Authority  shall  have the  right,  upon 90 days'  notice to the
Manager,   at  any  time  at  its  expense  to  cancel  or  replace  and  obtain
independently  all or any portion of the Required  Operating Period Insurance as
set forth in Appendix 4 hereto.

         SECTION 4.14.  INFORMATION.  (A) Information System. The Manager shall,
on and after the Closing Date  establish and maintain an  information  system to

Authority  review and  copying  of T&D  System  operating  data,  including  all
information necessary to verify calculations made pursuant to this Agreement.

         (B) Computer  Database.  The Manager shall maintain for the Authority a
computer  database which specifies each customer  served by the T&D System,  the
service  classification  applicable  to each  such  customer,  and  any  special
services  provided to each such  customer.  The  Authority  shall be entitled to
access such database at any time.

         (C) Ownership of Information and Documentation. The Authority will have
sole  ownership of  information  related to  customers  served by the T&D System
(except to the extent  such  information  is also owned by an  Affiliate  of the
Manager in its role as owner of the gas  utility)  and the  operation of the T&D
System  ("Authority  Customer & Operations  Data").  The Manager may not use any
Authority Customer & Operations Data for non-Authority  related purposes without
the Authority's prior written permission.  Such permission,  if granted, will be
granted on a nondiscriminatory basis. Neither the Manager nor any Affiliate will
(1) use customer information systems to extract, sort or otherwise use Authority
Customer and Operations Data  (including,  without  limitation,  name,  address,
telephone  number,  and energy usage) or (2) use mechanisms for customer  access
(including,  without limitation,  meter reading,  customers  representatives and
service call  center),  available  solely as a result of  Manager's  role as the
Manager of the T&D System, to market any services to customers served by the T&D
System  other than the services  provided  under this  Agreement.  To the extent
Authority Customer and Operations Data is available from other sources,  neither
the Manager nor its  Affiliates  shall be  precluded  from using in its business
such data obtained from other sources.

         SECTION 4.15.  MANAGER'S REPORTING  REQUIREMENTS.  (A) Monthly Reports.
The Manager shall provide the Authority and the Consulting Engineer with monthly

results of any environmental or other tests or monitoring  procedures  conducted

determine  to its  reasonable  satisfaction  the  propriety  of any  request for
payment or charge  hereunder.  The provisions of this  subsection  4.15(F) shall
survive the termination of this Agreement.

         SECTION  4.16.  FISCAL  AFFAIRS,  ACCOUNTING  AND RECORD  KEEPING.  (A)
General.   The  Manager  shall  maintain  possession  of  operating   equipment,
buildings,  materials and supplies,  maps, plans,  specifications,  and customer
billing records during the Term in accordance with Manager's customary practices
or in such manner as the Authority may reasonably require and shall duly account
to the Authority therefor.

         (B) Bank Deposits.  All cash held by the Manager for the account of the
Authority and all cash collected by the Manager for the account of the Authority
after the Closing Date shall be deposited on each  business day in bank accounts
in such bank as the Authority  may direct and upon such terms and  conditions as
may be specified by the Authority.

         (C) Record Keeping. In addition to the requirements of Section 4.15(F),
the Manager shall maintain  Authority's  fixed asset books and records for those
activities  performed  by the  Manager  in  general  conformity  with  municipal
electric  utility  accounting  standards or such other  standards as  reasonably
requested by the Authority.  When requested by the Authority,  the Manager shall
make  reasonable  changes in its standard  accounting  practices and  procedures
applied to the books and records of the T&D System.

         (D) Financial Audits.  Financial  information prepared as of the end of
each  Contract  Year,  shall be  certified  by an officer of the  Manager and an
independent  public  accountant who is  experienced  in electric  utility system
accounting  (which  accountant  shall be a  member  of a  nationally  recognized
accounting firm) and shall be delivered to the Authority within ninety (90) days
after the end of such  Contract  Year.  In addition,  the books and records upon
which the reports and statements required by this Article IV were prepared shall
be made  available by the Manager to the Authority for audit by the Authority or
the  Authority's  designated  independent  auditor  for a period  not to  exceed
twenty-four  (24)  months.  Upon  completion  of the  Authority's  audit or upon
expiration  of said  twenty-four-month  period,  the  statements,  invoices  and
records  shall be deemed to be  correct,  provided  no  written  protest  by the
Authority has been provided to the Manager. If the Authority's audit establishes
that the total of all  payments  by the  Authority  to the  Manager  exceeds the
amount  actually  due  hereunder,  then  Manager  shall  immediately  refund the
overpayment  to the  Authority  with interest at the Base Interest Rate from the
time such  overpayment  was made by the Authority to the Manager until repaid to
the  Authority.  If the  Authority's  audit  establishes  that the Authority has
underpaid the Manager,  then the Authority shall immediately pay the Manager the
underpayment,  with  interest  at the Base  Interest  Rate  from  the time  such
underpayment was due until paid by the Authority.


                                       23

         (E) Authority Bank  Accounts.  The Authority may establish and maintain
such special bank accounts as may be necessary or desirable,  including, but not
limited to, petty cash funds and local accounts  funds,  and shall establish the
rules and  procedures for access to any such accounts by the Manager and certain
of its designated employees.

         (F) Maps, Plans and Specifications. At the expiration of this Agreement
or at such time that the  Authority  (or a successor  manager of the T&D System)
assumes the functions  requiring the same,  the Manager shall  transfer to or at
the direction of the Authority all maps, plans and  specifications,  and records
pertaining to the T&D System in its possession at that time. Notwithstanding the
Manager's  possession of such maps, plans and specifications,  and records,  the
Manager  acknowledges that the same remain and are the property of the Authority
provided  that,  to the extent they relate to  facilities in addition to the T&D
System, the Manager shall retain a joint-ownership interest therein.

         SECTION 4.17.  INVENTORY  CONTROL.  The Manager shall,  in consultation
with, and with approval of, the  Authority,  maintain an inventory of equipment,
spare parts,  materials and supplies  consistent with the Contract Standards and
shall  maintain and document an inventory  control  program.  The Manager  shall
comply with the inventory  policy agreed to by the Authority and the Manager and
shall purchase and store  inventory in a manner  consistent  with the Annual T&D
Budget.  Inventory shall be billed to the Authority on a cost basis as used. The
Manager  shall  complete,  on an  agreed-upon  cycle  count  basis,  a  physical
inventory of the  equipment,  spare parts,  materials and supplies and reconcile
the same with the inventory  assets carried on the balance sheet and provide the
information to the Authority.

         SECTION 4.18.  CAPITAL ASSET CONTROL.  Within 90 days after the Closing
Date,  the  Authority  and the Manager  shall  complete an  inventory of all T&D
System  assets  constituting  "Capital  Assets" as such term shall be defined in
accordance  with  directions of the Authority.  Annually,  no later than 60 days
after the end of each Contract  Year, the Manager shall provide to the Authority
a list of all additions  and  retirements  of Capital  Assets from the perpetual
records set forth in  subsection  4.17 hereof,  with such detail as requested by
the Authority for  maintenance of these records.  Within 90 days after the sixth
anniversary  of the Closing  Date,  the Manager  shall  assist the  Authority in

dispose of, scrap, trade or sell any individual Capital Asset having an original
cost of $100,000 or more without the Authority's prior written approval.  To the
extent directed by the Authority,  all vehicles and equipment shall be purchased
in the name of the Authority and title shall be so issued.  As vehicles or other
equipment  are  acquired  by the Manager for the  Authority,  the Manager  shall
forward all titles to the Authority within 30 days after such acquisitions.

         SECTION 4.19.  WARRANTIES.  The Manager shall  maintain and enforce any
warranties or guarantees on any facilities,  vehicles,  equipment or other items
owned or  leased  by the  Authority  or  purchased  or  leased  on behalf of the

warranties or guarantees without the prior approval of the Authority.

         SECTION 4.20.  TECHNICAL  ASSISTANCE.  The Manager may contract for the
services of outside consultants,  suppliers,  manufacturers, or experts pursuant

         SECTION 4.21. PURCHASE OF EQUIPMENT, MATERIALS AND SERVICES. Consistent
with each  Annual T&D  Budget,  the Manager  shall  arrange for the  purchase or
rental for the account of the  Authority of equipment,  materials,  and supplies
and services  which are not  purchased  directly by the Authority or other items
necessary to properly operate and maintain the T&D System and


                                       24


<PAGE>

to  maintain  the  records  of the  Authority,  and to make such  additions  and
extensions  to the T&D System,  all as may be required  from time to time by the
Authority.  In this  connection,  any  contracts  let by the Manager shall be in
conformity  with  competitive  bidding  laws or  regulations  applicable  to the
Manager,  and, without the prior  authorization of such specific contract by the
Authority,  no such  contract  shall be for an amount  greater than  $250,000 or
extend  for a term  greater  than one year.  Subcontractors  shall be subject to
approval by the Authority in accordance with Section 9.10.

         SECTION 4.22.  OTHER  SERVICES.  (A) Bill  Payments.  The Manager shall
timely pay all bills related to the T&D System which are proper, appropriate and
not otherwise  disputed and which it has authority to pay and shall assure that,
to the extent within the Manager's  control,  no mechanic's or similar liens are
filed against any portion of the T&D System. In the event that the Manager fails
to pay any such bill timely,  the  Authority  shall have the right,  but not the
obligation,  to pay such bill and deduct the amount of such payment  (including,
but not limited to, any penalties which may be payable in respect of such bill),
plus  interest at the Base  Interest Rate from the time such payment was made by
the Authority until repaid the Manager and an administrative fee in an amount of
$50.

         (B)  Attendance at Meetings.  The Manager shall attend  meetings of the
Authority,  with  customers of the  Authority,  suppliers of the  Authority  and
others as reasonably requested by the Authority.

         SECTION 4.23.  EMPLOYEE PLANS.  During the term of this Agreement,  the
Manager shall fully comply with all of the terms of its Plans and all Applicable
Law relating  thereto.  Any liability arising by reason of the Manager's failure
to do so shall be borne by the Manager.  The Manager shall  promptly give notice
to the  Authority  of any default  under any Plans,  or any event which with the
passage of time or giving of notice would be a default  under any Plan and shall
not permit or suffer an event by the  Manager  which with the passage of time or
giving of notice would be a default under any Plan.

         SECTION 4.24.  HAZARDOUS WASTE.  With respect to the performance of its
obligations hereunder and to the extent required by the provisions of the System
Policies  and  Procedures  relating  to unusual  events in  connection  with the
handling,  transporting or disposing of Hazardous  Waste, the Manager shall give
notice to the  Authority,  and to any other  Governmental  Body as  required  by
Applicable  Law,  of its  intention  to  handle,  transport  or  dispose of such
Hazardous  Waste.  The Manager shall cause such  Hazardous  Waste to be handled,
transported  and  disposed  of at a Disposal  Facility  in  accordance  with the
Contract  Standards.  The costs  associated  with such  handling,  transport and
disposal  shall be borne by the  Authority,  unless the  Manager is  responsible
therefor under Section 6.10 hereof.

                                    ARTICLE V

                           MAJOR CAPITAL IMPROVEMENTS

               SECTION 5.1. MAJOR CAPITAL IMPROVEMENTS GENERALLY.

         (A) Generally.  The parties acknowledge that the Major Capital Plan and
Budget  provided  for herein is intended to provide  for the  implementation  of
major repairs and replacements not constituting  routine  maintenance of the T&D
System. In addition,  the Major Capital Plan and Budget is intended to recognize
that it will be necessary or desirable  from time to time during the Term hereof
to modify, alter or improve the T&D System from its then-current condition. Such
modifications  may be appropriate,  by way of example,  in order to increase the
efficiency  or improve the  performance  of the T&D  System,  to  anticipate  or
address  the  obsolescence  of any  portion of the T&D  System,  to respond to a
Change in Law or to reduce  Power and Energy  supply  costs.  All such  projects
which  constitute  Major Capital  Improvements  shall be made in accordance with
this Article and all Major Capital Improvements shall be owned by the Authority.
Under no circumstances shall any such Major Capital Improvement be considered to
constitute routine repair,  maintenance or replacement of the T&D System, all of
which  remain the  responsibility  of the  Manager to be  performed  pursuant to
Section  4.3  hereof.  The  Manager  shall make all Major  Capital  Improvements
described in the approved  Major Capital Plan and Budget in accordance  with the
provisions  thereof.  The  Manager  shall not make a Major  Capital  Improvement
without notifying the Authority and receiving written consent from the Authority
unless such Major  Capital  Improvement  is included in the then current  annual
Major  Capital Plan and Budget.  The  Authority  shall have the right,  when the
Manager  has  materially  exceeded  the Major  Capital  Plan and Budget as of an
interim date to require the Manager to defer specific Major Capital Improvements
planned for the  remainder of the year. In no event shall the approval or denial
of a  Manager-requested  Major Capital Improvement relieve the Manager of any of
its  performance  obligations  hereunder  or  entitle  the  Manager  to  a  cost
adjustment unless the Manager is entitled to recover such costs as an Other Cost
under Section 6.3 hereof or the Authority shall have agreed to such adjustments,
and except to the extent provided in Section 7.8. The requirements of Applicable
Law relating to Authority  procurement  of  construction  services  shall govern
whether, to what extent and in what manner the Authority may exercise its rights
to  contract  with the Manager  with  respect to any Major  Capital  Improvement
pursuant to this Article.

         (B)  Insurance and Other Third Party  Payments.  To the extent that any
Major Capital  Improvement  Costs that are incurred pursuant to this Article can
be recovered by the Manager from any insurer providing the Required Construction
Work Insurance or the Required Operating Period Insurance, or from another third
party,  the Manager shall exercise with due diligence such rights as it may have
to effect such  recovery.  The Manager shall give prompt  written  notice to the
Authority  of the  receipt  of any  such  recovery  which  shall be  applied  in
accordance  with the Bond  Resolution.  The Manager  shall provide the Authority
with copies of all  documentation,  and shall afford the  Authority a reasonable
opportunity to participate in and, if the Authority so determines, to direct all
conferences,  negotiations and litigation, regarding such insurance claims which
materially affect the Authority's interest under this Agreement.  All applicable
insurance  recoveries  shall be applied to reducing the cost of  restoration  or
reconstruction.

         (C) Cost Disputes.  The Manager agrees to use its best efforts to limit
the costs  incurred in making each Major  Capital  Improvement  consistent  with
Prudent Utility  Practice.  The Authority may,  without limiting the Authority's
obligation  to make  timely  payments  of any Major  Capital  Improvement  Costs
consistent  with  the  mutually  agreeable  payment  procedures  established  in
accordance with 5.1(D) hereof,  object to any Major Capital  Improvement Cost or
to the payment of any Major  Capital  Improvement  Cost on the grounds that such
Major Capital Improvement Cost or the amount being


                                       26


<PAGE>

charged  to the  Authority  was  improperly  computed,  that the  Major  Capital
Improvement  Costs  incurred  by the  Manager  were  unreasonable  for the  work
performed, or that the work performed by the Manager in making the Major Capital
Improvement  was materially  delayed or not completed due to a circumstance  for
which the  Manager  would be  responsible  for the costs of under  Section  6.10
hereof.

         (D) Major Capital Improvement Cost Payments.  Payment for Major Capital
Improvement  Costs will be made in accordance  with mutually  agreeable  payment
procedures which shall reflect customary  construction  drawdown,  milestone and
retainage provisions for similar projects.

         SECTION  5.2.   MAJOR  CAPITAL  PLAN  AND  BUDGET.   (A)   Preparation.
Contemporaneously  with the  preparation  of the Annual T&D Budget,  the Manager
shall  prepare a proposed  annual and five year  Major  Capital  Plan and Budget
concerning planned Major Capital  Improvement  projects (the "Major Capital Plan
and  Budget").  Such Major Capital Plan and Budget shall  identify,  among other
things:

         (i) proposed Major Capital Improvements by function (e.g. transmission,
substation,  distribution,  communication,  common plant,  and public works) and
project location;

         (ii) detailed project descriptions in the case of projects the costs of
which  exceed  a dollar  limit to be  agreed  upon by the  parties  prior to the
adoption of the initial Annual T&D Budget, and general descriptions in all other
cases;

         (iii) the planned  initiation  date of each  project  and the  expected
duration of such project;

         (iv) an estimate of the amount of the Major  Capital  Improvement  Cost
for each project,  including the dollar amount of capital  expenditures per year
if the project requires more than a year to complete;

         (v) a proposed drawdown schedule for each project;

         (vi)  an   explanation  of  the   relationship   to  other  planned  or
subsequently required capital additions or improvements of which each individual
Major Capital Improvement is a component;

         (vii) the anticipated useful life of each improvement or addition;

         (viii) the economic  and  engineering  justifications  for each capital
improvement or addition,  including, where applicable,  quantification of system
performance  changes  as a  result  of such  improvement  or  addition,  and the
expected effect,  if any, of the capital  improvement or addition on the ability
of the Manager to meet the Performance Guarantees;

         (ix) an  indication of whether the  improvement  or addition is planned
for performance by Manager work force or by third party contractor; and

         (x)  such  other  information  as may be  reasonably  requested  by the
Authority.

         Such  Major  Capital  Plan and Budget  shall  include  explanation  and
justification of costs in a form acceptable to the Authority. Whether particular
costs are capital or operation and maintenance costs payable from the Annual T&D
Budget  shall  be  determined  by the  Authority  in  accordance  with  the Bond
Resolution.


                                       27


<PAGE>

         (B) Schedule  for Major  Capital  Plan and Budget  Review.  The Manager
shall file a proposed  Major  Capital Plan and Budget with the  Authority at the
same time the Annual T&D Budget  proposal is filed  pursuant to Section  6.2(B).
The Authority shall provide  preliminary  comments on the Major Capital Plan and
Budget within 60 days after receipt,  provided  additional  time for review,  if
required, may be agreed to by the parties. The Manager shall make all changes to
the Major Capital Plan and Budget  reasonably  requested by the  Authority.  Any
proposed Major Capital Plan and Budget submitted to the Authority by the Manager
may be made  available  to the public by the  Authority at such time as it shall
deem  appropriate  for public review and comment.  The annual Major Capital Plan
and Budget will be approved by the Authority  before or  contemporaneously  with
the adoption of the Annual T&D Budget,  and prior to or  contemporaneously  with
the adoption of any rate adjustment by the Authority; provided that in the event
the Major  Capital Plan and Budget has not been  adopted by the  Authority as of
the beginning of a Contract  Year,  the Manager may undertake such Major Capital
Improvements  as reasonably  approved by the  Authority on a  project-by-project
basis.

         (C) Projects in Excess of $500,000. Other than for emergency repairs or
replacements,   at  the  Authority's   request,  the  Manager  shall  prepare  a
repair-or-replace  analysis for the Authority for repairs or replacements of the
T&D System  costing more than $500,000 if the same have not been approved in the
Annual T&D Budget.  The  Authority  shall decide  whether to have such repair or
replacement implemented.

         SECTION  5.3.   COST   DETERMINATION.   (A)  Basis  for  Major  Capital
Improvement Cost Determination. Major Capital Improvements, except those awarded
to the Manager as a result of the competitive procurement procedures outlined in
subsection  5.3(C)  hereof  shall be  performed,  whether by the  Manager's  own
workforce  or by a  Subcontractor,  at the  cost  of  the  service  without  any
multiplier fee or mark-up. Construction Work management and administration costs
will either be specifically budgeted on a project-specific  outsourced basis, or
such costs will be captured within the then current Direct Cost Budget.

         (B)  Source  of  Financing  of Major  Capital  Improvements.  (1) Major
Capital Improvements other than those for which the Manager is responsible under
Section  6.10 hereof will be financed by the  Authority in  accordance  with the
construction drawdown payment procedures  established pursuant to Section 5.1(D)
hereof,  provided  that the  Authority  and the  Manager  may  agree to have the
Manager  fund,  subject  to  reimbursement,  capital  additions  in the event of
emergency  costing in the  aggregate  not more than a dollar amount to be agreed
upon by the parties prior to the adoption of the initial Annual T&D Budget.

         (2) The Authority may in its sole discretion  determine whether to fund
particular  Major  Capital  Improvements  from  current  revenue  or  from  bond
proceeds.  The Manager shall  reflect the  principal and interest  repayment for
Major Capital  Improvement  Cost financing in its projections for System Revenue
Requirements in the Major Capital Plan and Budget.

         (C) Procurement and Contracting Procedures. (1) Along with its proposed
annual Major  Capital Plan and Budget,  the Manager  shall provide the Authority
with  an   explanation  of  its  proposed   process  for  procuring   equipment,
construction,  and other  services  related to  implementing  the Major  Capital
Improvements  so as to achieve  favorable  cost  completion of the Major Capital
Improvements.  Such  procurement  process shall be performed in accordance  with
Applicable  Law  and  Appendix  8.  Decisions  as  to  outsourcing  construction
management  shall be made in accordance  with the  procedures and criteria to be
determined in accordance with Appendix 8 hereto.

         (2) Wherever a Major Capital  Improvement is to be performed under this
Agreement,  the  provisions  and procedures set forth in Appendix 8 hereto shall
apply. In order to implement such


                                       28


<PAGE>

provisions with respect to any Major Capital  Improvement costing in excess of a
dollar  amount to be agreed  upon by the  parties  prior to the  adoption of the
initial Annual T&D Budget, the costs for which the Authority is responsible, the
Manager shall submit, at the Authority's discretion, a lump sum or an individual
element price proposal for such Major Capital Improvement, which shall be broken
out by the  categories  of work to be done  and  corresponding  costs.  Any such
proposal shall be deemed the Manager's  offer to the  Authority,  binding for 60
days, to perform the Major Capital  Improvement at the price quoted. The parties
shall  promptly  proceed to  negotiate  in good faith to reach  agreement on the
price to be paid to the Manager  for the Major  Capital  Improvement  and on the
effect of such Major  Capital  Improvement  on any costs or  obligations  of the
Manager under this  Agreement.  If the  Authority  does not accept the Manager's
proposal, the Authority may conduct a procurement to contract with a third-party
to undertake such Major Capital Improvement or, alternatively, the Authority may
require the Manager to solicit at least  three  competitive  bids for such Major
Capital  Improvements on a lump-sum or individual element basis, as requested by
the  Authority.  The Manager  shall  cooperate  with and assist the Authority in
connection with any procurement undertaken by the Authority.  To the extent that
the  Manager  or any  Affiliate  participates  as a  bidder  in any  competitive
solicitation  process,  the Manager shall establish  internal controls and other
procedures  satisfactory  to the  Authority  for the  purpose  of  assuring  the
integrity of the competitive solicitation. Except as the Authority may otherwise
direct,  competitive solicitations of bids shall be conducted in accordance with
the process and procedures to be established by the Authority. The Manager shall
promptly  notify the Authority of any  reasonable  objection to the  Authority's
inclusion of a party on a list of bidders.

         (D) Advancement of Funds for Major Capital  Improvements and Additions.
Once an annual Major Capital Plan and Budget is approved,  the  Authority  shall
advance funds in accordance with an agreed upon drawdown schedule established to
the mutual  satisfaction  of the  Authority and the Manager for payment of Major
Capital  Improvement  Costs.  Such drawdown schedule shall conform to Applicable
Law, including the provisions set forth in Appendix 13 hereto.

         (E) Major Capital Improvements Cost Savings Incentive. Manager shall be
entitled to incentive  payments for cost savings and  disincentive  payments for
cost  overruns  and delays in scheduled  completion  of approved  Major  Capital
Improvements  equal to 50% of all variances from the approved Major Capital Plan
and Budget;  provided,  however, that no such incentive or disincentive shall be
payable for cost  variances in excess of 15% of the approved  Major Capital Plan
and  Budget.  Such  incentive  and  disincentive  payments  will relate to Major
Capital  Improvements  which are not  subject to  competitive  bidding and those
projects  in which  Manager  serves as  construction  manager  over third  party
contracts  and not with  respect  to Major  Capital  Improvements  in which  the
Manager  serves as the general  contractor,  except as  otherwise  agreed by the
Authority  or as set  forth  in  the  terms  and  conditions  of  the  contract.
Incentives and disincentives will be trued-up upon the closing and acceptance by
the Authority of approved capital projects.

         SECTION 5.4 PUBLIC WORKS IMPROVEMENTS. (A) Generally. The Manager shall
not  undertake a Public  Works  Improvement  without  previously  notifying  the
Authority and receiving the written  consent of the Authority which shall not be
unreasonably delayed. In such notification, the Manager shall provide a proposed
project budget for such Public Works Improvement  containing information that is
consistent  with that  required  under  Section 5.2 hereof.  The budget for each
Public Works Improvement shall be subject to Authority  approval and the Manager
shall not undertake any Public Works  Improvement  until the budget therefor has
been  adopted.  The  parties  may agree to adjust any Public  Works  Improvement
budget in the event the governmentally  requested scope of work for such project
substantially changes from the originally budgeted scope of work.

         (B) Cost Disputes.  The Manager shall use its best efforts to limit the
costs  incurred in undertaking  each Public Works  Improvement  consistent  with
Prudent Utility Practice. The Authority


                                       29


<PAGE>

may, without limiting the Authority's obligations to make timely payments of any
Public Works  Improvement  Costs under  subsection  5.4(C)  consistent  with the
mutually  agreeable  payment  procedures  established in accordance with Section
5.4(E) hereof, object to any Public Works Improvement Costs or to the payment of
any  Public  Works  Improvement  Costs on the  grounds  that such  Public  Works
Improvement  Cost or the amount being charged to the  Authority  was  improperly
computed,  that the Public Works  Improvement Costs incurred by the Manager were
unreasonable for the work performed or that the work performed by the Manager in
undertaking the Public Works Improvement was materially delayed or not completed
due to a circumstance  for which the Manager would be responsible  for the costs
of under Section 6.10 hereof.

         (C) Cost  Determination.  Public Works Improvements shall be performed,
whether by the Manager's own workforce or by a Subcontractor, at the cost of the
service  without any multiplier  fee or mark-up;  provided,  however,  that such
costs  shall be reduced by all  reimbursements  or  payments  received  from the
applicable  Governmental  Body for the planning,  engineering,  procurement  and
completion  of  the  Public  Works  Improvement.   Construction  management  and
administration costs will either be specifically  budgeted on a project-specific
outsourced  basis or such costs will be captured  within the then current Direct
Cost Budget. Decisions as to outsourcing construction management of Public Works
Improvements  shall be made in accordance  with the  procedures and criteria set
forth in Appendix 8 hereto.

         (D) Public  Works  Improvements  Cost Savings  Incentives.  The Manager
shall be entitled to incentive  payments for cost savings and  disincentives for
cost  overruns and delays in  scheduled  completion  that result in  incremental
costs for approved  Public  Works  Improvement  as follows:  (a) no incentive or
disincentives  shall be payable for all variances from the approved Public Works
Improvement  project  budget between 0% and plus or minus 2%, and (b) 50% of all
variances  (whether  positive  or  negative)  from  the  approved  Public  Works
Improvement  budget  of 2.01%  or more.  Incentives  and  disincentives  will be
payable 60 days after the project  completion and acceptance by the Authority of
approved Public Works Improvements.

         (E)  Public  Works  Improvement  Costs  Estimate.   The  Manager  shall
recommend,  and the Authority  shall adopt,  an annual  reserve level for Public
Works Improvements. Such reserve level shall be identified in each Major Capital
Plan and Budget and 5-year planning budget,  although not included  therein,  in
order to  enable  estimation  of  total  cash  flows  for the T&D  System.  Such
estimates  will also be used by the  Authority  for  determination  of financial
reserve requirements for the T&D System.

         (F) Public Works  Improvement  Cost Payments.  Payment for Public Works
Improvement  Costs will be made in accordance  with mutually  agreeable  payment
procedures which shall reflect customary  construction  drawdown,  milestone and
retainage provisions for similar projects.

         SECTION  5.5.   MAJOR  CAPITAL   IMPROVEMENTS   FOR  WHICH  MANAGER  IS
RESPONSIBLE.   If  the  T&D  System  is  damaged  or   destroyed  by  reason  of
circumstances  for which the Manager is  responsible  under Section 6.10 hereof,
the Manager shall promptly proceed to make or cause to be made all Major Capital
Improvements   reasonably  necessary  to  permit  the  Manager  to  perform  its
obligations  under this Agreement.  The Manager shall give the Authority and the
Consulting Engineer written notice of, and reasonable  opportunity to review and
comment  upon,  any such  proposed  Major  Capital  Improvement.  All such Major
Capital  Improvements for which Manager is responsible  under Section 6.10 shall
be made at the  Manager's  sole cost and expense,  and the Manager  shall not be
entitled to any compensation from the Authority as a result thereof.

                                   ARTICLE VI

                            COMPENSATION AND BUDGETS

         SECTION  6.1.  SERVICE  FEE.  (A)  Formula.  Commencing  with the first
Billing  Period and for each Billing  Period during the Term of this  Agreement,
the Authority  shall pay the Manager a Service Fee for the services  provided by
the Manager under the terms of this  Agreement in accordance  with the following
formula:

                  SF   = FDF + TPC + VP + CIF + NCPI
                                              -
                                              
         Where

                  SF   = Service Fee

                  FDF  = Fixed Direct Fee

                  TPC = Third Party Costs

                  VP  = Variable Payment

                  CIF = Cost Incentive Fee

                  NCPI = Non-cost Performance Incentives and Disincentives

Each  component  of the Service Fee shall be  computed in  accordance  with this
Article and may be adjusted from time to time as provided in this Agreement. For
illustrative  purposes,  examples of the  calculation of the Service Fee payable
hereunder  are  attached as Appendix 12 hereto.  In addition to the Service Fee,
Manager  shall be entitled to payment for cost  overruns as set forth in Section
6.1(F).

         (B) Fixed Direct Fee. The Authority will make a monthly  payment to the
Manager  equal to ninety  (90%) of the approved  annual  Direct Cost Budget (the
"Fixed Direct Fee").  The monthly  allocation of such payment will be determined
by the  parties  prior  to the  adoption  of each  Annual  T&D  Budget  based on
historical monthly trends to minimize working capital costs.

         (C) Third Party Costs. The Authority will make a monthly payment to the
Manager for the  monthly  allocation  of the  approved  annual  Third Party Cost
Budget.  Monthly  allocation  of such payments will be determined by the parties
prior to the  adoption of each  Annual T&D Budget  based on  historical  monthly
trends to minimize working capital costs.

         (D)  Variable  Payment.  The  Manager  will be  entitled  to a Variable
Payment  equal to the lesser of (a) the  difference  between  actual Total Costs
(the sum of the actual Direct Costs and the actual Third Party Costs),  less the
sum of the Fixed  Direct Fee and the lesser of actual or  budgeted  Third  Party
Costs or (b) the  difference  between the approved Total Cost Budget (the sum of
the Direct  Cost  Budget and the Third  Party Cost  Budget)  less the sum of the
Fixed  Direct Fee and the lesser of the actual or budgeted  Third  Party  Costs.
Monthly  allocation  of such payment shall be determined by the parties based on
historical  monthly trends to minimize working capital costs. For administrative
ease,  the  calculation  of the monthly  Variable  Payment shall be based on the
difference between the Total Cost budget and the sum of the amounts paid for the
Fixed Direct Fee and Third Party Costs.


                                       31


<PAGE>

         (E)  Management  Fee,  Cost  Incentive  Fee  and  Non-cost  Performance
Incentives and Disincentives. To the extent actual Total Costs are less than the
approved  Total Cost Budget for the year,  the Manager shall be paid the portion
of its  Management  Fee,  described  within the  definition  of Direct  Costs in
subsection  6.2(A)  (relating to cost savings),  in an amount equal to such cost
savings up to a maximum of $5 million. Beyond such $5 million level, the Manager
will be paid a Cost  Incentive  Fee  equal  to 50% of such  additional  savings,
provided  that no  incentive  will be paid for  savings  in excess of 15% of the
Total Cost  Budget.  All savings  above this cap shall be for the benefit of the
Authority.  The  amounts  described  in this  subsection  shall  not be  payable
monthly,  but shall instead be paid as part of the Annual  Settlement  Statement
process in  accordance  with  Section  6.8  hereof.  The  Manager  shall also be
entitled to share in any  amounts  recovered  in  accordance  with  Section 4 of
Appendix 7 hereto.

         (F) Cost  Overruns.  To the extent  actual Total Costs,  excluding  the
Management  Fee,  are  greater  than the Total Cost  Budget,  excluding  the net
Management  Fee, for the applicable  Contract Year, the Manager shall absorb the
first  dollars of such  overruns,  up to a maximum  total of $15 million in each
Contract Year. For cost overruns in excess of this amount,  the Manager shall be
entitled  to a payment  through  the Annual  Settlement  Statement  equal to the
amount of such excess overruns (the "Overrun Payment").

         (G)  Limitations.  To the  extent  required  by the terms of the letter
ruling  obtained  from the  Internal  Revenue  Service  in  connection  with the
Agreement,  the  ratio  of (1) the sum of the  Variable  Payment  plus  the Cost
Incentive  Fee  plus  the  sum  of  the  Non-cost  Performance   Incentives  and
Disincentives (described in Section 6.4) plus the Overrun Payment divided by (2)
the sum of (a) the amounts  described  in (1) above and (b) the Fixed Direct Fee
shall not be greater than twenty percent (20%) in any Contract Year.

         (H) Carrying  Costs.  Interest  rates and charges due from one party to
the other for carrying costs for the timing of  reimbursements  for balances due
for  differences  between  the  lesser of  actual  Total  Costs or the  approved
budgeted Total Costs and the monthly payments for such costs shall be determined
as set forth in Section  6.8  hereof in  connection  with the Annual  Settlement
Statement.

         SECTION 6.2.  ANNUAL T&D BUDGET AND FIVE YEAR PLANNING  BUDGET PROCESS.
(A) General.  The Annual T&D Budget and the  Five-Year  Planning  Budget will be
established  in  accordance  with  subsection  6.2(B) and will  provide  for the
determination  and payment of the Manager's  costs of operating and  maintaining
the T&D System and performing its obligations hereunder,  inclusive of fees paid
to the Manager. The Annual T&D Budget and the Five-Year Planning Budget shall be
comprised of two broad categories:  Direct Costs (the "Direct Costs Budget") and
Third Party Costs (the "Third Party Costs  Budget").  These  categories of costs
shall  exclude  Incremental  Internal  Costs and  additional  Third  Party Costs
relating to Major Capital  Improvements,  Public Works  Improvements,  and Other
Costs.

         (1) Direct Cost Budget.  In establishing the Direct Cost Budget for the
initial  Annual T&D Budget  hereunder,  the Direct Cost Budget shall include (1)
amounts to compensate the Manager for Operation and  Maintenance  Services costs
anticipated to be reasonably predictable and incurred by the Manager through the
utilization of either its work force,  or its owned assets,  in carrying out its
responsibilities  under the Agreement (the "Direct Costs") and (2) the Manager's
fee ("Management  Fee"). Costs related to the Manager's work force shall include
compensation  paid  to  employees  of the  Manager  as  well  as an  appropriate
allocation of such costs of employees of the  Manager's  parent or affiliates to
the extent  such  employees  provide  service to the  Authority  pursuant to the
Agreement.  Costs  related  to the  Manager's  owned  assets  shall  include  an
appropriate  allocation of depreciation and return on the undepreciated  balance
and shall  include an  appropriate  allocation  for  projects in progress at the
Closing Date. The determination of depreciation and return to be allocated shall
be based upon historical costs


                                       32


<PAGE>

and an agreed upon  capital  structure.  The  Management  Fee shall be an annual
fixed amount of $15 million.  Of this  amount,  however,  $5 million must result
from cost  savings.  As a result,  the Direct  Cost  Budget  will  include a net
Management Fee of $10 million.

         (2) Third Party Cost Budget.  The Third Party Cost Budget shall include
amounts  for  reimbursement  of, on a dollar for  dollar  basis,  all  recurring
capital  or  operating  costs  incurred  by the  Manager  in  carrying  out  its
responsibilities under the Agreement and paid to parties other than Manager, its
parent or affiliates, and any of their employees (the "Third Party Costs"). Such
costs shall  include,  for example,  costs  incurred in respect of  professional
fees,  postage,  materials  and supplies,  third party  contract  labor,  rents,
property taxes on the Common Facilities, telecommunications, insurance, dues and
fees,  advertising,  and mutual assistance agreements with non-Affiliates of the
Manager.

         (3) Cost Incentive  Fees. The Manager shall be entitled to receive Cost
Incentive Fees, as provided in subsection 6.1(E) hereof,  for costs savings from
the amounts  included  for Direct  Costs and Third  Party Costs in the  approved
Annual T&D Budget.

         (B)  Annual  T&D  Budget  Preparation.   (1)  Generally.  On  the  date
determined in accordance with Schedule C to the Acquisition  Agreement to be the
date six months  preceding  the projected  Closing Date and  thereafter no later
than six months prior to the end of each Contract Year, the Manager will prepare
a recommended annual budget for the operation and maintenance, including routine
capital  projects not  constituting  Major Capital  Improvements or Public Works
Improvements,  of the T&D  System  and a  recommended  annual  budget  for total
revenue  requirements,  inclusive of the Authority's  own costs,  with the costs
that will be paid by the Authority to Manager under this Agreement  specifically
and separately identified (together,  the "Annual T&D Budget").  The recommended
Annual T&D Budget shall be accompanied  by a five year T&D planning  budget (the
"Five-Year  Planning  Budget").  The Authority will hold at least one hearing to
solicit public input on the initial budgets. The Annual T&D Budget and Five-Year
Planning  Budget  shall be divided  into a Direct  Cost Budget and a Third Party
Cost Budget in accordance  with the budget  categories  set forth in Appendix 10
hereto,  consistent  with the  general  definition  of such costs in  subsection
6.2(A) hereof. The initial Direct Cost Budget,  once established and approved by
the Authority,  will be indexed for each subsequent year during the Term of this
Agreement as described in Appendix 5. The Third Party Cost Budget,  as contained
in the Annual T&D Budget and the Five Year Planning  Budget,  will be determined
and approved annually. Each Annual T&D Budget and Five-Year Planning Budget will
be composed of the indexed  Direct Cost Budget and the annually  determined  and
approved  Third  Party Cost  Budget.  Direct  Costs and Third Party Costs in the
adopted  Annual T&D Budget  shall be  calculated  and included in such budget at
cost without mark-up.

         (2) Initial Budgets.  The Manager shall propose and the Authority shall
review, amend as appropriate and approve the Annual T&D Budget and the Five-Year
Planning  Budget for the first  Contract  Year prior to the Closing  Date.  Such
initial  Annual  T&D Budget  and  Five-Year  Planning  Budget  shall  reflect an
agreed-upon  estimate  of  adjustments  in  T&D  System  costs  attributable  to
productivity improvements to be undertaken by the Manager and in accordance with
the  Acquisition  Agreement,  estimated  synergy savings from the combination of
Long Island Lighting  Company and The Brooklyn Union Gas Company pursuant to the
BUGLILCO Agreement.

         (3) Direct Cost Budget  Preparation.  The amounts  included  for Direct
Costs in the  initial  Annual  T&D Budget  shall be based  upon the agreed  upon
disaggregated  T&D System costs portion of the proposed 1997 rate year budget in
the  LILCO  1996  rate  case  filing  with the  NYSPSC,  adjusted  to 1999  (the
anticipated  first  full  calendar  year  of  operation  under  the  Agreement).
Adjustments  to the 1997 base  budget  shall  include,  but not be  limited  to,
adjustment  of union labor costs in  accordance  with the  existing  union labor
contract, non-union labor costs in accordance with the Direct Cost Budget


                                       33


<PAGE>

Indices,  other  indices as used in the 1996 rate case filing to adjust from the
1997 rate year to the 1999 revenue  requirements  estimate,  addition of the net
Management Fee of $10 million and known changes in facts and circumstances. Such
Direct Cost Budget  shall also  consider  actual  historical  results  from 1996
through  the date of adoption  of the  initial  Annual T&D Budget  prepared on a
comparable  disaggregated  basis.  Payment  of any  bonus  or  incentive  pay to
officers  of the  Parent  shall not be part of the  Direct  Cost  Budget  unless
mutually agreed to in writing by the parties.

         Subsequent  annual Direct Cost Budgets  shall be calculated  based upon
the  initial  Direct Cost  Budget,  subject to  adjustments  for the Direct Cost
Budget Indices described in Appendix 5 hereto and as follows:

         (i) The union  labor  portion of the Direct  Costs will be  adjusted in
accordance with existing union contracts through February 13, 2001.  Thereafter,
the cost of union  labor and  benefits  will be  adjusted  based on Direct  Cost
Budget  Indices.  At the  Authority's  option,  Manager  will  consult  with the
Authority on all future  renegotiations  of union labor contracts prior to final
agreement and will keep the  Authority  apprised of labor  negotiations  as they
progress;

         (ii) All other portions of the Direct Cost budget,  including non-union
labor, will be adjusted for the appropriate Direct Cost Budget Indices set forth
in Appendix 5.

         (4) Third Party Costs Budget Preparation. If in any proposed Annual T&D
Budget or Five-Year  Planning Budget the Manager  proposes changes in components
of Third Party  Costs  (e.g.  rates for  professional  services,  unit costs for
materials and supplies,  postage rates, insurance premiums, etc.) from the prior
budgets due to claims by the Manager of changes in costs significantly different
from  previously  applicable  rates used in the  previously  adopted Third Party
Costs  Budget,  the  Manager  must  provide  documentation  of the basis of such
changes.  The Authority may require that the Manager  demonstrate  justification
for increases in components of Third Party Costs through  competitively  bidding
for contracts or services,  or through other means. If the Annual T&D Budget has
not been adopted by the Authority prior to the beginning of a Contract Year, the
Manager,  to the extent necessary to maintain T&D System reliability and safety,
shall be  authorized  to expend,  amounts up to the actual Third Party Costs for
the first three months of the prior Contract Year.

         (5) Rate  Recommendations  and Budget Review. The Annual T&D Budget and
Five-Year Planning Budget prepared by the Manager and submitted to the Authority
for review and approval  shall be accompanied  by any  Manager-recommended  rate
adjustments  for the  upcoming  year and shall be  submitted at least six months
before the anticipated  Closing Date and six months before the beginning of each
subsequent  Contract  Year.  The  Authority  shall  have 60 days to  review  the
proposed  Annual  T&D  Budget  and  Five-Year   Planning  Budget  and  any  rate
adjustments and to propose  modifications as it deems appropriate.  The parties'
objective  is to have the Annual T&D Budget and the  Five-Year  Planning  Budget
adopted at least two months before the  beginning of the next Contract  Year. If
there is a rate  adjustment,  the Manager,  at the  Authority's  request,  shall
expedite its preparation and discussions  with the Authority so as to enable the
public review process for a rate adjustment to begin sufficiently early to allow
approximately  four (4) months of public  review,  comment,  and adoption by the
Authority before the new rate year begins. All rate proposals will be subject to
public hearings prior to approval by the Authority.

         (6) Five-Year  Planning  Budget.  The Five-Year  Planning  Budget shall
include a projection  of the Direct Cost Budget based on the load  forecast most
recently  approved by the Authority and a projection of the applicable  indices.
The Manager acknowledges that the Authority's acceptance of the year 2 through 5
planning  budgets as contained  in the  Five-Year  Planning  Budget shall not be
deemed to  constitute  approval  of such  budgets,  although  these  later  year
planning budgets will be used


                                       34


<PAGE>

as guidance for the  reasonableness  of any  adjustments  to  subsequent  annual
budgets to be adopted by the Authority.

         (7) Budget Format.  The Annual T&D Budget and Five-Year Planning Budget
shall be in a form  acceptable  to the  Authority,  with the initial  Annual T&D
Budget and Five-Year Planning Budget to be prepared with the same categories and
levels of detail for  historical  costs and documented in a manner which enables
comparison to actual expenditures.  The Annual T&D Budget and Five-Year Planning
Budget  shall  include the type and format of  information  shown in Appendix 10
hereto.

         (8)  Accelerated  Budget  Preparation.  If,  in  the  Authority's  sole
opinion, trends in the cost of service, customer loads or other factors indicate
a need to  consider  changes in rates,  cost  allocation,  or rate  design,  the
Authority may request a revised budget and rate  recommendation from the Manager
or preparation of the budget on an accelerated schedule, with reasonable notice.
The Authority and the Manager shall agree on any  reasonable  incremental  costs
which may be subject to reimbursement for such accelerated budget preparation.

         (9) Manager  Availability at Forums.  At the  Authority's  request upon
reasonable notice,  the Manager shall provide,  in any public or private forums,
explanation  and support for the  Manager's  T&D System  management  activities,
including, without limitation,  activities relating to the Annual T&D Budget and
Five-Year  Planning  Budget,  the Major Capital Plan and Budget,  rates and rate
design.

         SECTION 6.3 OTHER COSTS. (A) "Other Costs" Definition.  (1) Other Costs
are those costs which cannot  reasonably be anticipated  and shall include those
costs the Manager and the  Authority  agree are not  included in the Direct Cost
Budget,  Third  Party  Cost  Budget or Major  Capital  Plan and  Budget  ("Other
Costs"). Other Costs include the Incremental Internal Costs and additional Third
Party Costs  incurred by the  Manager as a result of events  (including  but not
limited to major  storms and extreme  weather)  that  Manager and the  Authority
agree have caused costs to be incurred by the Manager to respond to  significant
(i) damage to or adverse affects on the T&D System, (ii) changes in the level of
required  maintenance  or operation of the T&D System,  or (iii) tasks which are
necessary for safety reasons. In addition,  Manager will be reimbursed for Other
Costs resulting from or as a consequence of:

          (i)  changes in work scope and  projects  agreed to by the Manager and
          the Authority;

          (ii) a Change in Law;

          (iii)  determinations  made by the  Authority  pursuant to Section 4.5
          resulting in changes in System Policies and Procedures; or

          (iv) the Authority's  assumption "of the day-to-day  direction" of the
          Manager pursuant to Section 7.4(B)(2).

None of the following  shall  constitute an event which can cause Other Costs to
arise:

          (i) general  economic  conditions,  interest or  inflation  rates,  or
          currency fluctuations or exchange rates,

          (ii) the  financial  condition  of the  Authority,  the  Manager,  the
          Guarantor, any of their Affiliates or any Subcontractor,


                                       35


<PAGE>

          (iii) the consequences of a failure by the Manager, the Guarantor, any
          Subcontractor,  any of their  Affiliates or any other person to adhere
          to the Contract Standards in the performance of any work hereunder;

          (iv) the  failure of the  Manager to secure  patents or licenses to be
          owned or possessed  by the Manager and its  Affiliates  in  connection
          with the technology necessary to perform their obligations hereunder;

          (v) union work rules, requirements or demands which have the effect of
          increasing  the  number  of  employees  employed  at the  T&D  System,
          reducing  the  operating  flexibility  of  the  Manager  or  otherwise
          increase the cost to the Manager of operating and  maintaining the T&D
          System, or

          (vi) the failure of any  Subcontractor  or supplier to furnish  labor,
          materials, services or equipment for any reason.

         (2)  "Incremental  Internal  Costs"  shall  include  those  incremental
internal  costs incurred by the Manager and approved by the Authority to provide
for Major  Capital  Improvements,  Public  Works  Improvements,  and Other Costs
pursuant to the Agreement to the extent such costs are not otherwise included as
a Direct Cost or a Third Party Cost.  Such costs  shall  include,  for  example,
unbudgeted  overtime wages for employees of the Manager or its Affiliates  whose
salaries are included,  directly or indirectly,  in the Direct Cost Budget,  and
wages and benefits for any additional  employees  hired to perform the task or a
task  contemplated  in the Direct  Cost Budget not able to be  performed  by the
Manager's  employees due to their  deployment as a result of such event, and any
incremental  allocation of costs related to employees of the Manager's parent or
affiliates.

         (3) The Authority and the Manager shall agree upon the occurrence of an
event that  qualifies as one that has or is  anticipated to lead to Other Costs.
The  Authority's  approval  of the  reimbursement  of Other  Costs  shall not be
unreasonably  withheld.  Other Costs will not be taken into consideration in any
determination of incentives or disincentives as contemplated in this Agreement.

         (B) Other  Costs  Reserve  Estimate.  Although  Other Costs will not be
budgeted, the Manager shall recommend,  and the Authority shall adopt, an annual
reserve level for Other Costs for each Annual T&D Budget and Five-Year  Planning
Budget to enable estimation of total System Revenue Requirements.  Such estimate
will  also be used by the  Authority  for  determination  of  financial  reserve
requirements for the T&D System.

         (C) Other Costs  Reimbursement.  The  Manager  will be  reimbursed  for
reasonably  incurred Other Costs.  Payment for such costs will be made as needed
from reserves  retained by the Authority.  Approved costs in excess of available
reserves will be reimbursed in a manner which minimizes working capital costs to
the Authority.  Other Costs shall be billed as incurred, but not more frequently
than on a monthly basis.  The Authority shall pay such invoice within 30 days of
receipt,  subject to a 10%  retention by the  Authority  pending  completion  of
review of such invoice.  The Authority shall have 60 days to review such invoice
and supporting  documentation after which time it shall pay the Manager the full
amount thereof,  unless the Authority  disputes any aspect of such invoice.  Any
amounts  determined  to be owing by one party to the other  through such dispute
resolution shall be paid, along with interest at the Base Interest Rate from the
date the  Authority  made its payment  under this  subsection  until the date of
payment of the disputed or retained amounts.

         SECTION 6.4. NON-COST  PERFORMANCE  INCENTIVES AND  DISINCENTIVES.  (A)
Generally. In addition to the cost saving incentives provided for in


                                       36


<PAGE>

Section 6.2, the Manager will be eligible for incentives for  performance  above
certain threshold target levels of performance standards ("Non-cost  Performance
Incentives")  and subject to disincentives  for performance  below certain other
threshold   minimum   performance   standard   levels   ("Non-cost   Performance
Disincentives"),  with an  intermediate  band of  performance  in which  neither
incentives nor disincentives  shall apply, for reliability,  worker safety,  and
customer service, all as described in Appendix 7 hereto.

         (B)  Adjustments  to Threshold  Levels.  The threshold  levels to which
Manager's  performance  is measured  for  purposes of  determining  the Non-cost
Performance  Incentives and Non-Cost  Performance  Disincentives as described in
Appendix 7, may be increased or decreased by the mutual agreement of the Parties
to reflect  material  effects,  if any, of (1)  increases in  Authority-approved
Annual  T&D  Budgets;  (2)  determinations  by  the  Authority  not  to  approve
maintenance or capital improvement projects as originally recommended by Manager
and not  otherwise  reflected in the annual T&D  Budgets;  (3) changes in System
Policies and Procedures;  or (4) changes in the scope of Manager's services from
that which is contemplated in this Agreement.

         (C) Limits on Incentives and Disincentives.  In any Contract Year in no
event  shall  the  total  of the  Non-cost  Performance  Incentives,  net of any
applicable Non-cost  Performance  Disincentives,  together with the System Power
Supply  Incentive/Disincentive   payable  under  Section  5.3.2  of  the  Energy
Management Agreement,  be greater than $7.5 million, nor will the total Non-cost
Performance Disincentives, net of any applicable Non-cost Performance Incentives
together  with the System  Power  Supply  Incentive/Disincentive  payable  under
Section 5.3.2 of the Energy Management Agreement be greater than $7.5 million.

         SECTION 6.5. AUTHORITY NON-PERFORMANCE.  (A) Costs of Construction Work
and of Operation and Maintenance.  If subsequent to the Closing Date,  caused by
an event the costs of which the Authority is responsible  for under Section 6.10
hereof, there shall be an increase in the Manager's cost of Construction Work or
Operation and  Maintenance  Services,  the amount of any such  incremental  cost
increase  shall  be borne  by the  Authority  to the  extent  it is  responsible
therefor  under Section 6.10 hereof and shall not be considered  for purposes of
calculating any incentive or disincentive hereunder.  The Manager shall give the
Authority and the Consulting Engineer prompt written notice of the occurrence of
any such  event,  including  in such  notice  as and to the  extent  known (1) a
description in reasonable detail of the reasons why such increase is due to such
an event,  (2) the  projected  amount of any increase in the  Manager's  cost of
Construction  Work  or  Operation  and  Maintenance  Services,   including  Cost
Substantiation therefor and any impact on the scheduled completion date, and (3)
the resulting  adjustment in the compensation  due hereunder.  The Authority may
object to any  adjustment  to the  compensation  due  hereunder  due to any such
increase in the Manager's cost of operation and maintenance for any reason under
this  Agreement,  including  the grounds  that such  adjustment  was  improperly
computed,  that such costs are  unreasonable  for the work performed,  that such
costs or the  manner  in which  the work was  carried  out was not a  reasonable
response to the event,  or that the event is something  for which the Manager is
responsible under Section 6.10 hereof has occurred.  Notification and resolution
of any such dispute shall be made in accordance  with the  provisions of Section
7.8 hereof.

         (B) Major Capital Improvements to Repair Damage Caused by Authority. If
at any time the T&D System is damaged or destroyed due to an event for which the
Authority is responsible under Section 6.10 hereof,  the Authority shall pay, in

(A) hereof, all Major Capital  Improvement Costs and adjustments as are required
to be made by the Authority pursuant to Article V hereof.

         SECTION 6.6.  MANAGER  NON-PERFORMANCE.  If  subsequent  to the Closing

<PAGE>

Authority's costs associated with performing obligations  hereunder,  the amount
of any such  incremental  cost  increase  shall be borne by the  Manager  to the
extent it is responsible  therefor under Section 6.10 hereof. If at any time the
T&D  System is  damaged or  destroyed  due to an event for which the  Manager is
responsible under Section 6.10 hereof, the Manager shall pay, in addition to and
not  in  substitution  for  the  payments  required  above,  all  Major  Capital
Improvement Costs and adjustments resulting therefrom.

         SECTION 6.7.  BILLING OF MAJOR  CAPITAL;  PUBLIC  WORKS.  Major Capital

         SECTION 6.8. ANNUAL SETTLEMENT. (A) Annual Settlement Statement. Within
60 days after the end of each  Contract  Year,  the Manager shall deliver to the
Authority an annual settlement statement (the "Annual Settlement  Statement") in
a mutually  agreed upon form,  certified as to accuracy and  completeness by the
Manager,  setting forth the actual aggregate Service Fee payable with respect to
such Contract Year and a reconciliation of such amount with the amounts actually
paid by the Authority  pursuant to the Billing  Statements  with respect to such
Contract Year, including, without limitation, all adjustments to the Service Fee
made  pursuant  to Article V hereof and this  Article VI, all  adjustments  made
pursuant to  subsection  6.8(B)  hereof.  If any amount is then in dispute,  the
Annual  Settlement  Statement  shall set forth the  Manager's  estimate  of such
amount and a final  reconciliation  of such amount  shall be made in the Billing
Statement for the Billing  Period  immediately  following the resolution of such
dispute. The Annual Settlement Statement shall also include an accounting of any
incentives or  disincentives  accrued during the applicable  Contract Year along
with  appropriate  supporting   documentation.   The  Authority  shall  have  an
opportunity to review such accounting  prior to payment and shall have access to
the  Manager's  books and records in order to confirm such  accounting  prior to
payment.  Such review will be performed  within 90 days of receipt of the Annual
Settlement Statement.

         (B) Payment of Amounts Owed.  During the first quarter of the following
Contract Year, the monthly  payments made to the Manager by the Authority  shall
be (i) reduced by any  overpayment  by the Authority  resulting  from the sum of
actual  Direct  Costs and actual  Third Party Costs being less than the payments
made by the  Authority to the Manager for such costs during the previous year or
(ii)  increased  to reflect any  Non-Cost  Performance  Incentive  earned by the
Manager  during the previous  year and/or any Overrun  Payment Due. In the final
Contract Year, such adjustments shall be made in the last month of such year for
the first nine months of the year, and a final adjustment will be made within 90
days after the end of the year.

         (C) Carrying  Costs.  Any amounts  determined in the Annual  Settlement
Statement to be owing by one party to the other, other than Non-Cost Performance
Incentives or Non-Cost Performance  Disincentives shall be paid with interest at
the Base Interest  Rate  calculated  from July 1 of the preceding  Contract Year
until the date of the Annual Settlement Statement.

         SECTION 6.9. AUTHORITY'S PAYMENT OBLIGATIONS. (A) Source of Payments by
Authority.  Amounts payable to Manager  hereunder are to be paid from T&D System
revenues  and  other  funds of the  Authority  available  for such  purposes  in
accordance with the terms of the Bond Resolution.

         (B)  Disputes.  If the  Authority  disputes  any  amount  billed by the
Manager in any Billing  Statement,  the Authority  shall pay that portion of the
billed amount which is not in dispute and shall provide the Manager with written
objection within 45 days of the receipt of such Billing Statement indicating the
portion of the billed  amount that is being  disputed and  providing all reasons
then known to the  Authority  for its  objection  to or  disagreement  with such
amount.  If the  Authority  and the Manager are not able to resolve such dispute
within 30 days  after the  Authority's  objection,  either  party may refer such
dispute for resolution in accordance with Section 7.8 hereof. If any such amount
is adjusted in the


                                       38


<PAGE>

Manager's  favor  pursuant to agreement,  mediation or otherwise,  the Authority
shall pay the amount of such adjustment to the Manager, with interest thereon at
the Base Interest Rate from the date such disputed amount was due the Manager to
the date of payment in full of such amount. Nothing contained in this subsection
shall limit the  authority  of any  authorized  officer of the  Authority or any
other  governmental  agency  pursuant  to  Applicable  Law to  raise  a  further
objection to any amount billed by the Manager  pursuant to an audit conducted by
the  Authority  or such  governmental  agency.  No  payment  of  amounts  by the
Authority  hereunder  shall be construed as or shall  constitute a waiver by the
Authority  of its rights to dispute  such  amounts,  to conduct a final audit or
reconciliation, or otherwise review the appropriateness of such amounts.

         SECTION  6.10.  ALLOCATION  OF RISK OF CERTAIN  COSTS AND  LIABILITIES.
Except to the extent due to  Authority  Fault (as  determined  by either a final
non-appealable order or judgment of a court of competent jurisdiction (including
administrative   tribunals)  or  a  final  non-appealable   binding  arbitration
decision), the Manager shall be responsible and liable to the Authority for, and
shall  not  be   entitled  to   reimbursement   from  the   Authority   for  any
Loss-and-Expense incurred by the Manager or the Authority,

               (a) due to any gross  negligence  or  willful  misconduct  by the
          Manager  during the period  commencing six months prior to the Closing
          Date to the  extent  LILCO  knew or should  have  known of such  gross
          negligence or willful  misconduct  and during the Term in carrying out
          its obligations hereunder,

               (b)  due  to any  violation  of or  failure  of  compliance  with
          Applicable  Law by the Manager  (except as provided  below) during the
          period  commencing  six months prior to the Closing Date to the extent
          LILCO  knew or should  have  known of such  violation  or  failure  of
          compliance and during the Term which materially and adversely affects

                    (i) the condition or operations of the T&D System,

                    (ii) the financial condition of the Authority,

                    (iii) the  performance  or ability of the Manager to perform
               its obligations under this Agreement, or

                    (iv) the cost of providing electric service to the customers
               of the T&D System,  provided,  however, that Manager shall not be
               responsible  and liable to the  Authority  under this  clause (b)
               with respect to any violation of, failure of compliance  with, or
               liability   under,   Environmental   Laws  (as   defined  in  the
               Acquisition Agreement) for which the Authority or the Manager may
               be strictly liable provided that Manager (or for actions prior to
               the  Closing  Date,  LILCO)  acted  in a manner  consistent  with
               Prudent Utility Practice.  Notwithstanding the foregoing, Manager
               shall in all events be liable for any fine or penalty  arising by
               reason  of  any  violation  of  or  failure  of  compliance  with
               Applicable   Law  for  acts  or  omissions  of  the  Manager  not
               consistent with Prudent Utility Practice,

               (c)  due to  any  criminal  violation  of  Applicable  Law by the
          Manager (or for actions prior to the Closing Date, LILCO), or

               (d) due to an event  which  gives rise to a cost not  included in
          the Direct Cost  Budget or Third Party Cost Budget or a cost  incurred
          with respect to Major Capital Improvements or


                                       39

          Public  Works  Improvements,  that is incurred by reason of actions or
          omissions of the Manager not consistent with Prudent Utility Practice.

         Any action or  omission  identified  in (a),  (b),  (c) or (d) shall be
determined  by either a final  non-appealable  order or  judgment  of a court of
competent  jurisdiction   (including   administrative   tribunals)  or  a  final
non-appealable  binding  arbitration  decision and shall be  attributable to the
Manager for purposes of the preceding sentence whether it is attributable to the
Manager or to any officer,  member,  agent,  employee or  representative  of the
Manager or any  Affiliate  and any  contractor,  Subcontractor  of any tier,  or
independent  contractor  selected to perform any work  hereunder not  previously
objected  to by the Manager to the extent  permitted  by Section 5.3 and related
dispute resolution provisions.

          no longer being contested by the Manager,  the Parent or the Guarantor
          nor until the order of the  adjudication  shall be  regarded  as final
          unless and until the same is no longer being  contested by the Manager

          and the Manager  shall agree that such failure is not capable of being
          cured  within the three year period,  then such  failure  shall not be
          deemed an Event of  Default  hereunder  if and so long as the  Manager
          shall  provide   assurances   satisfactory   to  the  Authority   that
          appropriate  steps have been and are being  taken to effect a cure and

          with any of its material  obligations  under the Guaranty  unless such
          failure or refusal is  excused by an  Uncontrollable  Circumstance  or
          Authority Fault;  except that no such failure or refusal  specified in
          clause (b) or (c) of this Section  7.2(A)(2) shall constitute an Event
          of Default  giving the Authority the right to terminate this Agreement
          for cause under this subsection unless:

                    (i) The  Authority  has given  prior  written  notice to the
               Manager or the Guarantor, as applicable, stating that a specified
               failure  or  refusal  to  perform   exists  which  will,   unless

               reasonable  period  of  time,  but not more  than 60  days,  from
               receipt  of the  notice  given  pursuant  to  clause  (i) of this
               subsection  (but  if the  Manager  or the  Guarantor  shall  have
               diligently   taken  steps  to  correct  such  default   within  a
               reasonable period of time, the same shall not constitute an Event

               continuing to take such steps to correct such default).

          the Authority to perform any material  obligation under this Agreement
          unless  such  failure  or  refusal  is  excused  by an  Uncontrollable
          Circumstance or Manager Fault;  except that no such failure or refusal
          to pay or perform  shall  constitute  an Event of  Default  giving the

          Section unless:

                    (a) The  Manager  has  given  prior  written  notice  to the
               Authority  stating that a specified failure or refusal to perform
               exists which will, unless corrected, constitute a material breach
               of this Agreement on the part of the Authority and which will, in
               its opinion, give the Manager a right to terminate this Agreement
               for cause under this  Section  unless such  default is  corrected
               within a reasonable period of time, and

                    (b) The Authority has neither  challenged in an  appropriate
               forum the  Manager's  conclusion  that such failure or refusal to

               default  within a reasonable  period of time but not more than 60
               days from the date of the notice given  pursuant to clause (a) of
               this subsection (but if the Authority shall have diligently taken
               steps to correct such default within a reasonable period of time,
               the same shall not  constitute an Event of Default for as long as
               the  Authority is  continuing  to take such steps to correct such
               default).

               (3)  Change of  Control  of LILCO.  A change of  control of LILCO

          authority, political subdivision or other instrumentality of the State
          or any political subdivision thereof.

         SECTION 7.4.  PROCEDURE FOR TERMINATION FOR CAUSE. (A) Two-Year Notice.
If any party shall have a right of termination for cause in accordance with this
Article VII, the same may be  exercised  by notice of  termination  given to the

insolvency default or a Change of Control,  simultaneously with, or, in the case
of an Event of Default  specified in clause (f) or (g) of  subsection  7.2(A)(1)
hereof,  six  months)  the date of  termination  specified  in such  notice (the
"Termination Date").

         (B)  Termination  by  Authority.  (1) Access.  In the event an Event of
Default of the Manager  occurs and the  Authority  issues a  termination  notice
described in subsection  (A) hereof,  from the date of such  issuance  until the
Termination Date, the Authority shall have unrestricted  access to all areas of,
and  all  information,  data  and  records  concerning,  the T&D  System  and to
Manager's  personnel  necessary to monitor the performance of the Manager and to
ensure that the Manager  complies with the provisions of this  Agreement  during
such time period (the "Termination Notice Period").

         (2) Assumption of Responsibilities. At the Authority's sole option, the
Authority may elect at any time during the  Termination  Notice Period to direct

the Authority shall  reimburse the Manager for its resulting Cost  Substantiated
incremental  costs  incurred,  and the  Manager  shall no longer be  eligible to
receive  any  performance   incentives   otherwise   payable  hereunder  nor  be
responsible for the payment of any performance  disincentives  otherwise payable
under this Agreement; provided that the Manager shall be entitled to receive any
performance  incentives otherwise payable hereunder and shall be responsible for
any  performance  disincentives  otherwise  payable  hereunder  for  the  period
preceding such assumption of day-to-day operations.

         SECTION 7.5.  CERTAIN  OBLIGATIONS  OF THE MANAGER UPON  TERMINATION OR
EXPIRATION. (A) Obligations on Termination or Expiration.  Upon a termination of
the Manager's  right to perform this  Agreement  under Section 7.2 hereof or the
expiration of this  Agreement in accordance  with the terms hereof,  the Manager
shall  cooperate  in the  smooth  transition  to the new  manager  and,  without
limiting  the  generality  of the  foregoing,  in addition  to those  rights and
obligations under Schedule F to the Acquisition Agreement shall:

          System;

          termination of this Agreement,  promptly under each policy of Required
          Construction  Work Insurance and Required  Operation  Period Insurance
          (with a copy of each such  notice to the  Authority),  but  permit the
          Authority to continue  and/or assign such  policies  thereafter at its
          own expense, if possible; and

               (16) take such other actions,  and execute such other  documents,
          as may be necessary to effectuate  and confirm the foregoing  matters,
          or as  may  be  otherwise  necessary  or  desirable  to  minimize  the
          Authority's  costs,  and take no action which will increase any amount
          payable to the Authority under this Agreement.

         (B) Additional  Obligations.  The Manager shall also provide, and shall
use its  best  reasonable  efforts  to  cause  its  Subcontractors  to  provide,

reimburse the Manager  within 60 days of the date of the  Manager's  invoice all
mutually  agreeable  costs incurred by the Manager in satisfying the requirement
of subsections (A) and (B) hereof, subject to Cost Substantiation.

         SECTION 7.6. NO WAIVERS. No action of the Authority or Manager pursuant
to this Agreement (including, but not limited to, any investigation or payment),
and no failure to act,  shall  constitute  a waiver by either party of the other
party's  compliance with any term or provision of this  Agreement.  No course of
dealing or delay by the Authority or Manager in exercising  any right,  power or
remedy  under this  Agreement  shall  operate as a waiver  thereof or  otherwise
prejudice  such  party's  rights,  powers  and  remedies.  No single or  partial
exercise of (or failure to exercise) any right, power or remedy of the Authority
or Manager under this  Agreement  shall  preclude any other or further  exercise
thereof or the exercise of any other right, power or remedy.

         SECTION 7.7. FORUM FOR DISPUTE RESOLUTION. Subject to the provisions of
Section 7.8, it is the express  intention of the parties that all legal  actions
and proceedings  related to this Agreement or to the T&D System or to any rights
or any  relationship  between the parties arising  therefrom shall be solely and
exclusively  initiated and  maintained in courts of the State of New York having
appropriate  jurisdiction;  provided,  however,  that  except  in the  case of a
termination due to a change in control or bankruptcy or insolvency, either party
may refer a challenge to the  termination  of this  Agreement to an  independent
arbitrator,  following the use of expedited  limited  mediation  provided for in
Section 7.8 hereof.  During such arbitration process, the two-year notice period
provided  for in Section 7.4 hereof  shall  continue  to run and this  Agreement
shall terminate at the end of such period,  unless a final,  binding ruling that
the  termination  of  this  Agreement  was  improper  has  been  issued  by such
arbitrator.

         SECTION 7.8. NON-BINDING MEDIATION; ARBITRATION.

         (A) Dispute Resolution.  Any dispute arising out of or relating to this
Agreement shall be resolved in accordance with the procedures  specified in this
Section,  which  shall  constitute  the sole and  exclusive  procedures  for the
resolution of such disputes.

         (B)  Negotiation and  Non-Binding  Mediation.  The parties agree to use
their best efforts to settle  promptly any disputes or claims  arising out of or
relating to this Agreement through  negotiation  conducted in good faith between
executives having authority to reach such a settlement. Either party hereto may,
by written notice to the other party, refer any such dispute or claim for advice
or  resolution by mediation by an  Independent  Engineer,  financial  advisor or
other  suitable  mediator.  The parties shall mutually agree on the selection of
such  mediator.  If the  parties  are unable to agree,  the  parties  shall each
designate a qualified mediator who, together,  shall choose the mediator for the
particular  dispute or claim. If the mediator is unable,  within 30 days of such
referral,  to reach a determination  as to the dispute that is acceptable to the
parties hereto, the matter shall be referred to applicable Legal Proceedings.

         All negotiations and mediation  discussions  pursuant to this paragraph
shall  be  confidential  subject  to  Applicable  Law and  shall be  treated  as
compromise and settlement  negotiations for purposes of Federal Rule of Evidence
408 and applicable state rules of evidence.

         (C)  Arbitration.  Any  dispute  arising  out of or  relating  to  this
Agreement  or  the  breach,  termination,  or  validity  thereof,  except  for a
termination due to a Change in Control or due to a bankruptcy or insolvency or a
failure to provide,  renew, reinstate or replace the credit enhancement required
pursuant to Section 9.1 which dispute has not been resolved by a negotiation  or
mediation as


                                       46


<PAGE>

provided in  subsection  7.8(B)  hereof within 30 days from the date that either
negotiations or mediation shall have been first  requested,  shall be settled by
arbitration   before  three   independent   and   impartial   arbitrators   (the
"Arbitrators")  in  accordance  with the  then  current  rules  of the  American
Arbitration  Association,  except to the extent such rules are inconsistent with
any provision of this Agreement,  in which case the provisions of this Agreement
shall be followed,  and except that the arbitrations  under this Agreement shall
not be administered  by the American  Arbitration  Association.  The Arbitrators
shall be (a) independent of the parties and  disinterested in the outcome of the
dispute,  provided  that  residents  of Long  Island  shall  not be deemed to be
interested  merely by virtue of their  residence on Long Island,  (b) attorneys,
accountants,  investment bankers,  commercial bankers or engineers familiar with
contracts  governing the operation of electric utility assets, and (c) qualified
in the subject area of the issue in dispute.  The Arbitrators shall be chosen by
the parties,  with each party  choosing  one  arbitrator  and those  arbitrators
choosing the third Arbitrator. Judgment on the award rendered by the Arbitrators
may be  entered  in any  court  in the  State of New  York  having  jurisdiction
thereof.   If  either  party  refused  to  participate  in  good  faith  in  the
negotiations or mediation proceedings described in subsection 7.8(B)hereof,  the
other may initiate  arbitration at any time after such refusal  without  waiting
for the  expiration  of the  applicable  time  period.  Except  as  provided  in
subsection 7.8(D) hereof relating to provisional remedies, the Arbitrators shall
decide  all  aspects  of  any  dispute   brought  to  them  including   attorney
disqualification and the timeliness of the making of any claim.

         (D)  Provisional  Relief.  Either party may,  without  prejudice to any
negotiation,  mediation,  or  arbitration  procedures,  proceed  in any court to
obtain provisional judicial relief if, in the such party's sole discretion, such
action is necessary to avoid imminent irreparable harm, to provide uninterrupted
electrical  and other  services,  or to  preserve  the  status quo  pending  the
conclusion of the dispute procedures specified in this Section.

         (E)  Obligation to Repair.  It is the intention of the parties that the
Manager's operation and maintenance  obligations  hereunder shall be implemented
by the Manager in accordance with this Agreement,  notwithstanding the existence
of any dispute hereunder,  including without limitation,  responsibility for the
costs  therefor.  Such  actions by the Manager  shall in no case  prejudice  its
rights thereafter to dispute its responsibility for the costs therefor.

         (F) Awards.  The Arbitrators  shall have no authority to award punitive
damages  or any other  damages  aside  from the  prevailing  party's  actual and
consequential damages plus interest at the Base Interest Rate from the date such
damages were incurred.  The Arbitrators shall not have the authority to make any
ruling,  finding,  or award that does not conform to the terms and conditions of
this Agreement.  The Arbitrators may award reasonable  attorneys' fees and costs
of the  arbitration.  The  Arbitrator's  award shall be in writing and shall set
forth the factual and legal bases for the award.

         (G) Information Exchange.  The Arbitrators shall have the discretion to
order a pre-hearing exchange of information by the parties,  including,  without
limitation,  the production of requested documents, the exchange of summaries of
testimony of proposed witnesses,  and the examination by disposition of parties.
The  parties  hereby  agree to produce  all such  information  as ordered by the
Arbitrators and shall certify that they have provided all applicable information
and that such information is true, accurate and complete.

         (H) Site of Arbitration.  The site of any Arbitration  brought pursuant
to this Agreement shall be either Mineola, New York or Hauppauge, New York.

         SECTION 7.9.  AUTHORITY  EMERGENCY POWERS.  Should the Manager,  due to
Uncontrollable  Circumstances or any other reason whatsoever, fail, refuse or be
unable to provide any or all Operation and Maintenance Services and Construction
Work  contemplated  hereby and the Authority or any Governmental Body finds that
such failure endangers or menaces the public health, safety or welfare, then, in
any of those events and to the extent of such failure,  the Authority shall have
the right, upon notice to the Manager,  during the period of such emergency,  to
take  possession  of and use any or all of the  Operating  Assets  necessary  to
transmit and  distribute  Power and Energy which the Manager would  otherwise be
obligated to transmit and  distribute.  The Manager agrees that in such event it
will fully  cooperate with the Authority to effect such a temporary  transfer of
possession of the Operating  Assets for Authority's use of the same. The Manager
agrees that, in such event,  the Authority may take possession of and use any or
all of the Operating Assets for the above-mentioned  purposes without paying the
Manager or any other person any additional  charges or  compensation  whatsoever
for such possession and use; provided, however, that if such emergency is due to
Uncontrollable Circumstances,  the Authority shall reimburse the Manager for its
Cost-Substantiated  costs  incurred  due to  such a  transfer  of the  Operating
Assets. The parties acknowledge that if the Authority takes emergency possession
of the  Operating  Assets,  any  applicable  cure  period  provided  for in this
Agreement  for the  Manager's  benefit  shall be tolled  until  such time as the
Manager resumes  possession of the Operating  Assets.  The Authority may operate
the Operating Assets with Authority employees,  or cause the Operating Assets to
be  operated  by  subcontractors  to the  Authority  or  through  the use of the
Manager's employees, and the Manager shall make its employees available for such
purposes.  It is  further  agreed  that the  Authority  may at any time,  at its
discretion,  relinquish  possession of any or all of the Operating Assets to the
Manager and thereupon  demand that the Manager resume the operations as provided
in the Agreement.  It is specifically understood and agreed that the Authority's
exercise of its rights under this Section:  (1) does not  constitute a taking of
private  property  for which  payment  must be made other  than as  specifically
provided for in this Section;  (2) shall not create any liability on the part of
the  Authority  to the Manager;  and (3) that the  indemnity  provisions  of the
Agreement of Section 9.3 hereof covering the Authority and the Manager are meant
to include  circumstances  arising under this Section.  The Authority's right to
retain temporary  emergency  possession of the Operating Assets,  and to operate
the T&D  System  shall  terminate  at the  earlier  of:  (1) the time  when such
services can, in the judgment of the  Authority,  be resumed by the Manager,  or
(if earlier) (2) the time when the Authority no longer reasonably  requires such
Operating Assets, as determined by the Authority.

         SECTION 7.10. WAIVER OF CERTAIN DEFENSES. The Manager acknowledges that
it is responsible for the day-to-day operation and maintenance of the T&D System
and  the  design,  construction,  startup  and  testing  of  the  Major  Capital
Improvements  and Public Works  Improvements  and agrees that,  unless otherwise
permitted  pursuant to the  provisions  of this  Agreement  with  respect to the
occurrence  of   Uncontrollable   Circumstances,   and  without   limiting  such
provisions,  it shall  not  assert  (i)  impossibility  or  impracticability  of
performance,  (ii) lack of fitness for use or operation of the T&D System, (iii)
the existence,  non-existence,  occurrence or  non-occurrence of any foreseen or
unforeseen  fact,  event or  contingency  that may be a basic  assumption of the
Manager, (iv) commercial frustration of purposes or (v) contract of adhesion, as
a defense against any claim by the Authority against the Manager.

                                  ARTICLE VIII

                                      TERM

         SECTION 8.1. TERM OF AGREEMENT.  This Agreement shall become  effective
on the  Contract  Date,  and shall  continue  in effect  until the eighth  (8th)
anniversary  of the Closing Date (the  "Term"),  unless  earlier  terminated  in
accordance  with its  terms,  in which  event  the Term  shall be deemed to have
expired  as of the  date  of  such  termination.  All  rights,  obligations  and
liabilities of the parties hereto shall commence on the Closing Date, subject to
the terms and conditions  hereof. The Authority shall have no obligation to make
Service  Fee  payments   hereunder  until  the  Closing  Date.  The  rights  and
obligations of the parties hereto pursuant to Sections 3.1(E),  4.2(D),  4.2(E),
4.3(E),  4.14(C),  4.15(F),  4.16(D),  4.16(F), 4.24, 6.3, 6.10, 7.1, 7.4(B)(2),
7.5, 7.7, 7.8, 7.10, 8.3, 9.1(C), 9.2, 9.3, 9.4 and 9.5 hereof shall survive the
termination  or  expiration  of  this  Agreement,  and no  such  termination  or
expiration  of this  Agreement  shall limit or otherwise  affect the  respective
rights and  obligations  of the parties hereto accrued prior to the date of such
termination or expiration.  At the end of the Term of this Agreement,  all other
obligations of the parties hereunder shall terminate unless extended.

         SECTION 8.2. MANDATORY  COMPETITIVE  SELECTION OF FUTURE MANAGERS.  The
Manager  hereby  acknowledges  that the  Authority  will  commence and conduct a
competitive  procurement for T&D System management  services following the fifth
anniversary  of the  Closing  Date.  The  Manager  shall  have  the  right or be
ineligible,  as the case may be, to submit a bid in such procurement on the same
basis as other bidders;  provided that if this Agreement is terminated due to an
Event of Default of the Manager,  the Manager shall not have the right to submit
a bid in such procurement. The Manager shall cooperate with the Authority during
such procurement process,  including,  by way of example,  providing information
and  documents  requested  by the  Authority  for  dissemination  to bidders and
providing access to the T&D System for such bidders.

         SECTION  8.3.  EXIT  TEST.  An exit  test  (the  "Exit  Test")  will be
commenced six months prior to the expiration or termination of this Agreement to
confirm (1) that the Manager has  performed  the  maintenance  and Major Capital
Improvement and Public Work Improvements  activities which were budgeted for the
final  year  of  the  Agreement  or as  otherwise  previously  approved  by  the
Authority,  in such  final  year and (2)  that the  Manager  has  completed  any
remedial   activities  to  cure   maintenance   deficiencies  or  Major  Capital
Improvements and Public Works Improvements  which were previously  determined to
be incomplete as noted by the Authority  pursuant to the most recently conducted
review of the  condition  of the T&D  System  which  review  shall be  conducted
annually.  The Exit Test shall be carried out in accordance  with the provisions
of Appendix 6 hereto. If, as a result of such Exit Test, an independent engineer
selected by the Authority and agreed to by the Manager,  finds that maintenance,
Major  Capital  Improvement  and  Public  Works  Improvements,  replacement,  or
remedial  activities  described in (1) and (2) above have not been  performed in
accordance with this Agreement and that the Authority has provided the funds for
such  activities  as part of the payments  made during such final year or in the
case of items noted as  deficiencies  or incomplete  items pursuant to (2) above
were funded by the Authority in a previous year,  then the Manager shall, in its
discretion,   either  perform  such   incomplete   maintenance,   Major  Capital
Improvement,  Public Works  Improvements,  replacement,  or remedial  activities
without  further  compensation  from the  Authority,  or  within  90 days  after
termination of the Agreement,  the Manager shall reimburse the Authority for the
cost to complete such work.

                                     GENERAL

         SECTION  9.1.  MANAGER  TO  REMAIN   AFFILIATE  OF  GUARANTOR;   CREDIT
ENHANCEMENT IN CERTAIN CIRCUMSTANCES.  (A) Limitations.  The Manager agrees that
it will remain an Affiliate of the Guarantor.

         (B) Material Decline in the Guarantor's  Credit Standing.  For purposes
of this Section,  a "Material Decline in the Guarantor's  Credit Standing" shall
be deemed to have  occurred if (1) in the event that the Guarantor has long-term
senior debt  outstanding  which has a credit  rating by a Rating  Service,  such
rating by a Rating Service is established or is reduced below  investment  grade
level or (2) in the event the  Guarantor  does not have  long-term  senior  debt
outstanding  which has a credit rating by a Rating Service and the Guarantor has
a credit  rating by a Rating  Service,  such  credit  rating is  established  or
reduced below investment grade level, or (3) in the event the Guarantor does not
have  long-term  senior debt  outstanding  which has a credit rating by a Rating
Service and the Guarantor does not have a credit rating by a Rating Service,  in
which event the  Guarantor  shall seek a credit  rating for the Guaranty  from a
Rating Service,  such rating is established or is reduced below investment grade
level or if no rating is established.  The Manager  immediately shall notify the
Authority of any Material Decline in the Guarantor's Credit Standing.

         (C)  Credit  Enhancement.  If, at any time  during the Term  hereof,  a
Material Decline in the Guarantor's  Credit Standing  occurs,  the Manager shall
immediately  notify  the  Authority  thereof  and,  within  30 days  after  such
occurrence,  shall provide  credit  enhancement  of its  obligations  hereunder,
GENCO's  obligations  under the Power Supply  Agreement and the Energy Manager's
obligations under the Energy  Management  Agreement at its sole cost and expense

the Energy Manager's  obligations under the Energy Management Agreement provided
by a corporation  or financial  institution  whose  long-term  senior debt is or
would be rated investment grade by a Rating Service or (2) an irrevocable letter
of credit in form and  substance  satisfactory  to the  Authority  securing  the
Manager's  obligations  hereunder,  GENCO's  obligations  under the Power Supply
Agreement  and the Energy  Manager's  obligations  under the  Energy  Management
Agreement in a face amount of  $60,000,000  provided by a financial  institution
whose  long-term  senior  debt is rated  investment  grade by a Rating  Service;
provided  that if any such letter of credit is drawn upon in the aggregate in an
amount  equal to 50% of the face  value of such  letter of credit,  the  Manager
shall,  within 30 days  thereafter,  supplement or replace such letter of credit
with an additional letter of credit such that the total amount of such letter of
credit then  available  equals $60 MILLION.  The amount of such letter of credit
shall  be  reduced  by  $30  million  if the  Energy  Management  Agreement  has
theretofore  been or is  thereafter  terminated  and by $4  million if the Power
Supply  Agreement  has  theretofore  been  or  is  thereafter  terminated,  such
obligation to continue until the  expiration or  termination of this  Agreement,

the  Authority  nor the Manager  shall be liable to the other for any failure or
delay in  performance of any  obligation  under this  Agreement  (other than any
payment at the time due and owing) to the  extent  due to the  occurrence  of an
Uncontrollable Circumstance.

         (B)  Notice,  Mitigation.  The  party  experiencing  an  Uncontrollable
Circumstance  shall  notify the other  party by  hardcopy  telecommunication  or

if any,  by which  Other  Costs  may  arise as a result  of such  Uncontrollable
Circumstance,  (4) its estimated  impact on the other  obligations of such party
under this Agreement and (5) potential  mitigating  actions which might be taken

approximate  amount of such cost  reductions.  Each party shall  provide  prompt
written notice of the cessation of such  Uncontrollable  Circumstance.  Whenever
such act,  event or condition  shall occur,  the party  claiming to be adversely
affected  thereby  shall,  as  promptly  as  reasonably  possible,  use its best
reasonable  efforts to  eliminate  the cause  therefor,  reduce costs and resume
performance  under this  Agreement.  While the delay  continues,  the Manager or
Authority  shall give  notice to the other  party with a copy to the  Consulting
Engineer,   before  the  first  day  of  each  succeeding  month,  updating  the
information previously submitted.  The Manager shall furnish promptly (if and to
the  extent  available  to  the  Manager)  any  additional  documents  or  other
information relating to the Uncontrollable  Circumstance reasonably requested by
the Consulting Engineer or the Authority.

         (C) Conditions to Relief on Account of Uncontrollable Circumstances. If
and to the extent that  Uncontrollable  Circumstances  interfere with,  delay or
increase  the cost of the  Manager's  performing  any  Construction  Work or the
Operation and Maintenance Services in accordance  herewith,  and the Manager has
given timely notice as required by subsection  9.2(B) hereof,  the Manager shall
be entitled to an increase or  extension  in the Service Fee or the schedule for
performance  equal to the  amount  of the  increased  cost or the time lost as a
result  thereof.  In the event that the Manager  believes it is entitled to with
respect  to  compensation  or any  other  relief  hereunder  on  account  of any
Uncontrollable  Circumstance,  it shall furnish the Authority  written notice of
the specific  relief  requested and detailing the event giving rise to the claim
within 45 days  after the  giving of notice  delivered  pursuant  to  subsection
9.2(B) hereof. Within 45 days after receipt of such a timely submission from the
Manager, the Authority shall issue a written  determination as to the extent, if
any, it concurs with the Manager's claim for relief, and the reasons therefor.

         (D) Acceptance of Relief Constitutes  Release. The Manager's acceptance
of  compensation  or schedule  relief under this Section shall be construed as a
release of the Authority by the Manager (and all persons  claiming by,  through,
or under  the  Manager)  for any and all  Loss-and-Expense  resulting  from,  or
otherwise attributable to, the event giving rise to the relief claimed.

         SECTION 9.3.  INDEMNIFICATION.  (A) Indemnification by the Manager. The
Manager  agrees that to the extent  permitted by law it will protect,  indemnify
and hold harmless the Authority and its  respective  representatives,  trustees,
officers,  employees and  subcontractors  (as applicable in the  circumstances),
(the "Authority  Indemnified Parties") from and against (and pay the full amount
of) any  Loss-and-Expense  and will defend the Authority  Indemnified Parties in
any suit, including appeals, for personal injury to, or death of, any person, or
loss or damage to  property  arising  out of any matter for which the Manager is
responsible  under  Section  6.10 hereof.  The Manager  shall not,  however,  be
required to reimburse  or  indemnify  any  Authority  Indemnified  Party for any
Loss-and-Expense  to the  extent  any  such  Loss-and-Expense  is due to (a) any
matter for which the Authority is responsible under Section 6.10 hereof, (b) the
negligence or other wrongful conduct of any Authority Indemnified Party, (c) any
Uncontrollable   Circumstance,   (d)  any  act  or  omission  of  any  Authority
Indemnified Party judicially determined to be responsible for or contributing to
the Loss-and-Expense, or (e) any matter for which the risk has been specifically
allocated  to the  Authority  hereunder.  An Authority  Indemnified  Party shall
promptly  notify the Manager of the  assertion of any claim against it for which
it is  entitled  to  be  indemnified  hereunder,  shall  give  the  Manager  the
opportunity to defend such claim, and shall not settle


                                       51


<PAGE>

the claim without the approval of the Manager.  The Manager shall be entitled to
control  the  handling of any such claim and to defend or settle any such claim,
in its sole  discretion,  with  counsel of its own choosing  that is  reasonably
acceptable to the Authority Indemnified Parties; provided, however, that, in the
case of any such  settlement,  the Manager shall obtain  written  release of all
liability of the Authority Indemnified Parties, in form and substance reasonably
acceptable to the Authority Indemnified Parties.  Notwithstanding the foregoing,
each Authority Indemnified Party shall have the right to employ its own separate
counsel in  connection  with,  and to  participate  in (but,  except as provided
below,  not  control)  the defense of, such claim,  but the fees and expenses of
such  counsel  incurred  after  notice to the Manager of its  assumption  of the
defense  thereof  shall be at the expense of such  Authority  Indemnified  Party
unless:

          (i)  the employment of counsel by such Authority Indemnified Party has
               been authorized by the Manager;


          (ii) counsel to such Authority Indemnified Party shall have reasonably
               concluded that there may be a conflict on any  significant  issue
               between the Manager and such Authority  Indemnified  Party in the
               conduct of the defense of such claim; or

          (iii)the Manager  shall not in fact have employed  counsel  reasonably
               acceptable  to the  Authority  Indemnified  Party to  assume  the
               defense of such  claim  within  twenty  (20) days  following  the
               receipt  by  the  Manager  of  the  notice  from  the   Authority
               Indemnified  Party  regarding  the  assertion  of the  applicable
               claim,

in each of which  cases the fees and  expenses  of  counsel  for such  Authority
Indemnified  Party shall be at the expense of the  Manager;  provided,  however,
that, with respect to clauses (ii) and (iii) of this sentence, the Manager shall
not be obligated  to pay the fees and  expenses of more than one law firm,  plus
local counsel if necessary in each relevant jurisdiction, for all such Authority
Indemnified Parties with respect to any claims arising out of the same events or
facts or the same series of events or facts.  The Manager shall not be entitled,
without the consent of such Authority  Indemnified  Party,  to assume or control
the defense of any claim as to which counsel to such Authority Indemnified Party
shall have  reasonably  made the conclusion  that there may be a conflict on any
significant  issue between the Manager and such Authority  Indemnified  Party in
the  conduct of the  defense of such  claim as set forth in clause  (ii)  above,
provided  that the foregoing  limitation  shall apply only with respect to those
issues for which there may be such a conflict. These indemnification  provisions
are for the protection of the Authority  Indemnified  Parties only and shall not
establish, of themselves, any liability to third parties. The provisions of this
subsection 9.3(A) shall survive termination of this Agreement.

         (B) Indemnification by the Authority.  The Authority agrees that to the
extent  permitted  by law, it will  protect,  indemnify  and hold  harmless  the
Manager  and  its  Affiliates   and  their   respective   officers,   directors,
Subcontractors  (as applicable in the circumstances) and employees (the "Manager
Indemnified  Parties")  from  and  against  (and  pay the  full  amount  of) any
Loss-and-Expense,  and will defend the Manager  Indemnified Parties in any suit,
including  appeals,  for personal injury to, or death of, any person, or loss or
damage  to  property  arising  out of any  matter  for which  the  Authority  is
responsible  under Section 6.10 hereof.  The Authority  shall not,  however,  be
required  to  reimburse  or  indemnify  any  Manager  Indemnified  Party for any
Loss-and-Expense  to the  extent  any  such  Loss-and-Expense  is due to (a) any
matter for which the Manager is responsible  under Section 6.10 hereof,  (b) the
negligence or other wrongful conduct of any Manager  Indemnified  Party, (c) any
Uncontrollable Circumstance,  (d) any act or omission of any Manager Indemnified
Party  judicially  determined  to be  responsible  for  or  contributing  to the
Loss-and-Expense,  (e) any  matter  for  which  the risk  has been  specifically
allocated to the Manager hereunder.  A Manager  Indemnified Party shall promptly
notify the


                                       52


<PAGE>

Authority of the  assertion of any claim  against it for which it is entitled to
be  indemnified  hereunder,  shall give the Authority the  opportunity to defend
such  claim,  and shall  not  settle  the  claim  without  the  approval  of the
Authority.  The Authority  shall be entitled to control the handling of any such
claim and to  defend or settle  any such  claim,  in its sole  discretion,  with
counsel  of its  own  choosing  that is  reasonably  acceptable  to the  Manager
Indemnified Party; provided,  however, that, in the case of any such settlement,
the  Authority  shall  obtain  written  release of all  liability of the Manager
Indemnified  Party, in form and substance  reasonably  acceptable to the Manager
Indemnified Party. Notwithstanding the foregoing, each Manager Indemnified Party
shall have the right to employ its own separate  counsel in connection with, and
to participate in (but,  except as provided below,  not control) the defense of,
such claim,  but the fees and expenses of such counsel  incurred after notice to
the Authority of its  assumption of the defense  thereof shall be at the expense
of such Manager Indemnified Party unless:


          (i)  the employment of counsel by such Manager  Indemnified  Party has
               been authorized by the Authority;

          (ii) counsel to such Manager  Indemnified  Party shall have reasonably
               concluded that there may be a conflict on any  significant  issue
               between the Authority and such Manager  Indemnified  Party in the
               conduct of the defense of such claim; or

          (iii)the Authority shall not in fact have employed counsel  reasonably
               acceptable  to the  Authority  Indemnified  Party to  assume  the
               defense of such  claim  within  twenty  (20) days  following  the
               receipt  by  the   Authority  of  the  notice  from  the  Manager
               Indemnified  Party  regarding  the  assertion  of the  applicable
               claim,

in each of which  cases  the fees  and  expenses  of  counsel  for such  Manager
Indemnified Party shall be at the expense of the Authority;  provided,  however,
that,  with respect to clauses (ii) and (iii) of this  sentence,  the  Authority
shall not be  obligated  to pay the fees and expenses of more than one law firm,
plus local  counsel if necessary  in each  relevant  jurisdiction,  for all such
Manager  Indemnified  Parties with respect to any claims arising out of the same
events or facts or the same series of events or facts.  The Authority  shall not
be entitled, without the consent of such Manager Indemnified Party, to assume or
control the defense of any claim as to which counsel to such Manager Indemnified
Party shall have  reasonably made the conclusion that there may be a conflict on
any significant  issue between the Authority and such Manager  Indemnified Party
in the  conduct of the  defense of such claim as set forth in clause (ii) above,
provided  that the foregoing  limitation  shall apply only with respect to those
issues for which there may be such a conflict. These indemnification  provisions
are for the  protection  of the Manager  Indemnified  Parties only and shall not
establish, of themselves, any liability to third parties. The provisions of this
Section 9.3(B) shall survive termination of this Agreement.

         SECTION  9.4.  PROPERTY  RIGHTS.  The  Manager  shall  pay,  subject to
Authority   reimbursement   as  a  Third   Party   Cost,   all   royalties   and
non-governmental  license fees relating to the operation and  maintenance of the
T&D  System  and the  design,  construction  and  testing  of any Major  Capital
Improvements.  The  Manager  agrees  that it will  protect,  indemnify  and hold
harmless the  Authority and any of the  Authority  Indemnified  Parties from and
against all Loss-and-Expenses, and will defend the Authority Indemnified Parties
in any suit,  including  appeals,  arising out of or related to  infringement of
such patent,  trademark or copyright relating to, or for the unauthorized use of
trade  secrets by reason of, the operation or  maintenance  of the T&D System or
the design, construction or testing of any Major Capital Improvements, or at its
option,  will acquire the rights of use under  infringed  patents,  or modify or
replace infringing equipment with equipment equivalent in quality,  performance,
useful life and technical characteristics and development so that such equipment
does not so infringe.  The Manager shall not, however,  be required to reimburse
or indemnify any person for any Loss-and-Expense


                                       53

<PAGE>

due to the negligence or wrongful conduct of such person. The provisions of this
Section 9.4 shall survive  termination of this Agreement,  but only for a period
of time equal to the unexpired  statute of  limitations  applicable to any claim
for which indemnification might be required.

         SECTION 9.5. PROPRIETARY INFORMATION.  (A) Manager Request. The parties
hereto hereby acknowledge that the Manager has a proprietary interest in certain
information that may be furnished  pursuant to the provisions of this Agreement.
The  Manager  acknowledges  that  the  Authority  may be  required  to  disclose
information  upon request under Applicable Law. The Manager shall have the right
to request the  Authority in writing not to publicly  disclose  any  information
which  the  Manager  believes  to be  proprietary  and  not  subject  to  public
disclosure  under  Applicable  Law,  any such  request to be  accompanied  by an
explanation of its reasons for such belief. Any information which is the subject
of such a request  shall be  clearly  marked on all pages,  shall be bound,  and
shall be  physically  separate  from  all  non-proprietary  information.  At the
Manager's  request,  the  Authority  and its agents,  consultants  and employees
(including  the  Consulting  Engineer)  given access to such  information  shall
execute and comply with the terms of a  confidentiality  agreement in a mutually
acceptable form, subject to Applicable Law.

         (B) Authority  Non-Disclosure.  In the event the  Authority  receives a
request from the public for the  disclosure  of any  information  designated  as
proprietary  by the Manager  pursuant to  subsection  (A) of this  Section,  the
Authority (1) shall use reasonable  efforts,  consistent with Applicable Law, to
provide  notice to the Manager of the request prior to any  disclosure,  and (2)
shall  use  reasonable  efforts,  consistent  with  Applicable  Law,  to keep in
confidence  and not  disclose  such  information  unless it is entitled to do so
pursuant to the provisions of subsection (C) of this Section.  The Manager shall
indemnify,  hold harmless and defend the Authority against all  Loss-and-Expense
incurred from the withholding from public  disclosure of information  designated
as  proprietary  by the  Manager or  otherwise  requested  by the  Manager to be
withheld.

         (C)  Permitted   Disclosures.   Notwithstanding   any  confidential  or
proprietary  designation thereof by the Manager,  the Authority may disclose the
following:  (1)  information  which  is  known  to  the  Authority  without  any
restriction as to disclosure or use at the time it is furnished, (2) information
which is or becomes  generally  available  to the public  without  breach of any
agreement,  (3)  information  which  is  received  from a  third  party  without
limitation  or  restriction  on such third party or the Authority at the time of
disclosure, or (4) following notice to the Manager pursuant to subsection (B) of
this Section, information which, in the opinion of counsel for the Authority, is
required to be or may be disclosed under any Applicable Law, an order of a court
of competent jurisdiction, or a lawful subpoena.

         SECTION 9.6. RELATIONSHIP OF THE PARTIES. Except as otherwise expressly
provided herein,  neither party to this Agreement shall have any  responsibility
whatsoever with respect to services provided or contractual  obligations assumed
by the other  party  hereto,  and nothing in this  Agreement  shall be deemed to
constitute  either party a partner,  agent or legal  representative of the other
party or to create any fiduciary relationship between the parties.

         SECTION 9.7. ASSIGNMENT AND TRANSFER. This Agreement may be assigned by
either  party  hereto only with the prior  written  consent of the other  party,
except that  without the consent of the other party (1) the  Authority  may make
such  assignments,  create such security  interests in its rights  hereunder and
pledge such monies  receivable  hereunder as may be required in connection  with
issuance of Revenue Bonds; (2) the Authority may assign its rights,  obligations
and interests hereunder, or transfer such rights and obligations by operation of
law,  to any other  governmental  entity  or to a  subsidiary  of the  Authority
provided that the successor  entity gives  reasonable  assurances to the Manager
that it will be able to fulfill the Authority's  obligations hereunder;  and (3)
the Manager may


                                       54


<PAGE>

assign its rights,  obligations  and  interests  hereunder  to the Parent or any
Affiliate  thereof;   provided,   however,  that  with  respect  to  clause  (3)
immediately  above,  the Manager may not,  without the consent of the Authority,
make  any  assignment  or  other  transfer  to  any  person  of its  rights  and
obligations  under this  Agreement  unless the  Guaranty  is and remains in full
force and effect and unless the Guarantor or a majority-owned direct or indirect
subsidiary of the  Guarantor  shall have control of and  responsibility  for the
Operation and Maintenance Services and any Construction Work. Effective upon the
Closing Date,  the Authority  may assign its rights,  obligations  and interests
hereunder to Long Island  Lighting  Company and the Manager  shall assign all of
its rights,  obligations and interests  hereunder to the Parent or any Affiliate
thereof pursuant to clause 3 above.

         SECTION  9.8.  INTEREST  ON OVERDUE  OBLIGATIONS.  Except as  otherwise
provided herein, all amounts due hereunder, whether as damages, credits, revenue
or  reimbursements,  that are not paid when due shall bear  interest at the Base
Interest  Rate on the amount  outstanding  from time to time,  on the basis of a
365-day year, counting the actual number of days elapsed,  and all such interest
accrued at any time shall,  to the extent  permitted  by law, be deemed added to
the amount due, as accrued.  The parties  agree that the Base Interest Rate will
apply to  payments  under  this  Agreement  as  specified  herein in lieu of any
different  rate that would  otherwise  apply  generally to late  payments by the
Authority.

         SECTION 9.9. NO DISCRIMINATION.  The Manager shall not discriminate nor
permit   discrimination   by  any  of  its  officers,   employees,   agents  and
representatives  against  any person  because  of age,  race,  color,  religion,
national  origin,  sex or,  with  respect to  otherwise  qualified  individuals,
handicap.  The Manager will take all actions reasonably necessary to ensure that
applicants  are  employed,  and that  employees are treated  during  employment,
without regard to their age, race,  color,  religion,  sex,  national origin or,
with respect to otherwise  qualified  individuals,  handicap.  Such action shall
include, without limitation,  recruitment and recruitment advertising; layoff or
termination;  upgrading,  demotion,  transfer,  rates  of pay or  other  form of
compensation; and selection for training, including apprenticeship.  The Manager
shall impose the  non-discrimination  provisions of this Section 9.9 by contract
on all Subcontractors  hired to perform work related to the T&D System and shall
take all reasonable  actions  necessary to enforce such provisions.  The Manager
will post in  conspicuous  places,  available to employees  and  applicants  for
employment,  notices  setting  forth the  provisions  of this  nondiscrimination
clause.

         SECTION 9.10. APPROVAL OF SUBCONTRACTORS.  The Authority shall have the
right to approve all  Subcontractors  engaged to perform any work related to the
T&D System,  or any portion of the Construction Work or Operation and Management
Services.  For  contracts  in  which  at  least  $250,000  would  be  paid  to a
Subcontractor  in a Contract Year the Authority  shall have the right to approve
such Subcontractors on a  contract-by-contract  basis. Prior to the beginning of
each Contract Year Manager shall propose a list of  pre-approved  Subcontractors
for the  Authority's  review and  approval,  which shall  specify  the  proposed
categories  of  potential  work  under  contracts  pursuant  to which  less than
$250,000 would be paid for each such  Subcontractors for such Contract Year. The
Manager  also shall  furnish  the  Authority,  along  with such  list,  with all
information requested by the Authority to the extent reasonably available to the
Manager pertaining to the proposed Subcontractors and categories of subcontracts
in the following  areas:  (1) the  qualification  and experience of the proposed
subcontractors for the services to be performed or for the supplies or equipment
to be  furnished,  (2) any  conflicts  of  interest,  (3) any  record  of felony
criminal  convictions or pending felony criminal  investigations,  (4) any final
judicial  or  administrative  finding  or  adjudication  of  illegal  employment
discrimination,  and (5) any known final judicial or  administrative  finding or
adjudication of non-performance in contracts with the Authority or the State. In
its sole discretion,  Authority may approve any proposed  Subcontractor for such
Contract Year or for a designated shorter period or for a specific  subcontract.
If a  Subcontractor  is approved  for a Contract  Year or shorter  period,  such
Subcontractor shall be deemed to be approved for


                                       55


<PAGE>

the  specified  categories  of potential  work for the duration of such Contract
Year or shorter period unless the Authority otherwise notifies the Manager.  The
approval or withholding  thereof by the Authority of any proposed  Subcontractor
shall  not  create  any  liability  of  the  Authority  to  the  Manager,   such
Subcontractor, third parties or otherwise.

         SECTION 9.11.  ACTIONS OF THE AUTHORITY IN ITS  GOVERNMENTAL  CAPACITY.
Nothing  in this  Agreement  shall be  interpreted  as  limiting  the rights and
obligations of the Authority in its governmental or regulatory  capacity,  or as
limiting  the  right of the  Manager  to bring  any  legal  action  against  the
Authority,  not based on this  Agreement,  arising out of any act or omission of
the Authority in its governmental or regulatory capacity.

         SECTION 9.12.  BINDING EFFECT.  This Agreement shall become binding and
effective on the Closing Date and shall thereafter bind and inure to the benefit
of the  parties  hereto and any  successor  or  assignee  acquiring  an interest
hereunder in compliance with the provisions of Section 9.7 hereof.

         SECTION  9.13.  AMENDMENTS.  Neither this  Agreement  nor any provision
hereof may be changed,  modified,  amended or waived except by written agreement
duly executed by all parties.

         SECTION  9.14.  NOTICES.  Any  notices or  communications  required  or

reasonably  requested  by the  other  in  order  to  give  full  effect  to this
Agreement.  The Authority and the Manager, in order to carry out this Agreement,
each shall use all reasonable efforts to provide such information,  execute such
further  instruments  and  documents  and take such actions as may be reasonably
requested  by the  other  and  not  inconsistent  with  the  provisions  of this
Agreement  and not  involving  the  assumption  of  obligations  or  liabilities
different  from or in excess of or in addition to those  expressly  provided for
herein.

         SECTION 9.16. NO THIRD PARTY  BENEFICIARIES.  Unless  specifically  set

hereby deemed incorporated in this Agreement at this place. To the extent of any
conflict between any other provision of this Agreement and Appendix 13, Appendix

the Term of this Agreement.

         2001,  union labor and benefit costs included in the Direct Cost Budget
         shall be  escalated  annually at the  beginning of each  contract  year
         using the U.S. Labor Department's Bureau of Labor Statistics Employment
         Cost Index (ECI) for union  workers in service-  producing  industries.
         Prior to  February  14,  2001,  escalations  in union labor and benefit
         costs  will be based on the  percent  wage  increases  outlined  in the
         provisions of the existing  labor  contracts.  The initial  Direct Cost
         Budget shall be adjusted each year based on the difference  between the
         1997 base year index and the current year index.

                         NON-COST PERFORMANCE INCENTIVES
                        AND DISINCENTIVES; PILOT PAYMENTS

         The following are the formulas for non-cost performance  incentives and
disincentives  in accordance  with Section  6.4(A) of the  Agreement  related to
reliability, worker safety, and customer service.

1.       OPERATING AREA RELIABILITY

         The Manager will earn an incentive or incur a disincentive  computed in
accordance  with a formula  based on specific  minimum,  midpoint and  objective
System  Average  Annual  Interruption  Frequency  Index  ("SAIFI")  and Customer
Average  Interruption  Duration  Index  ("CAIDI")  levels  for  each of the four
divisions as set forth  below.  For  purposes of this  incentive,  interruptions
during  major  storms are excluded  from the SAIFI and CAIDI  statistics.  Major
storms,  as  currently  defined by the NYSPSC,  are  periods of adverse  weather
during which service  interruptions  affect at least 10 percent of the customers
in an operating area and/or result in customers being without  electric  service
for a duration of at least 24 hours.

at or below the  minimum  level for each  division,  the  Manager  shall incur a
disincentive of $800,000 for SAIFI and $200,000 for CAIDI. For performance at or
in excess of the objective level for each division, the Manager shall receive an
incentive of $800,000 for SAIFI and $300,000 for CAIDI.  For  performance at the
midpoint  levels and below the  objective  levels,  the  Manager  shall  receive
one-half of the full incentive payment.  For performance between the minimum and
midpoint   levels  (the  "dead  band"),   the  Manager  shall  neither  incur  a
disincentive  nor receive an incentive  payment.  The total  possible  incentive
payment can be earned by  equaling or  exceeding  the  objective  level for each
measure  in  each  division.   The  maximum  total   reliability   incentive  or
disincentive shall be $4,000,000.

2.       WORKER SAFETY

         The Authority shall provide an annual incentive  payment to the Manager
of $100,000 per Chargeable  Accident less than 75 rated on a three-year  rolling
average.  The  Manager  shall  neither  earn an  incentive  payment  nor incur a
disincentive  payment  obligation  for periods in which the number of chargeable
accidents  falls between 75 and 80,  inclusive  (the "dead  band").  The Manager
shall incur a penalty of $100,000 per Chargeable Accident for years in which the


                                       7-2


<PAGE>

three-year  rolling  average number of Chargeable  Accidents is greater than the
80. Data from years prior to the Commencement  Date shall be used to compute the
three-year averages in the first and second years. The upper and lower limits of
the dead band shall be adjusted  annually in  proportion to the changes in total
workforce  (full time  equivalents)  for the departments to which this incentive
plan applies: Electric Design & Construction,  Electric Service, Electric System
Operations,  and Meter Readers. The total annual incentive or disincentive shall
not exceed $1,000,000.

         A Chargeable  Accident,  for  incentive  purposes,  are those which are
charged to the involved  employee's  department in accordance with LILCO General
Operating Procedure 10103,  Exhibit 9.9. It is any injury or illness suffered by
an employee,  while at work, that requires offsite  treatment  administered by a
physician  or  registered  professional  under  the  direction  of a  physician,
(whether the treatment is received at a clinic,  doctor's office,  hospital,  or
other  medical  facility)  with  the  exception  of  injuries  in the  following
categories:

         (1)      company sanctioned sports activities
         (2)      assaults by customers
         (3)      insect bites
         (4)      animal bites
         (5)      injuries   resulting  from  running   to  safety  while  being
                  threatened with attack by customer, animal or insect
         (6)      medical conditions not related to work (diabetic shock, etc.)
         (7)      certain  occupational  illnesses  that  occur  due to  chronic
                  exposure  in  the  work  place  specifically:   Carpal  Tunnel
                  Syndrome, respiratory illnesses (such as Asbestosis),


                                       7-3


<PAGE>

                  chronic  hearing  loss,  or other  medical  conditions  due to
                  exposure to  substances  in work place  (rashes  from  unknown
                  substances, etc.)
         (8)      Motor Vehicle accidents in which the employee is not at fault.

For the purpose of Section 7.2, the Minimum  Worker Safety  Standard shall be 95
Chargeable Accidents on a three-year rolling average basis.

3.       CUSTOMER SERVICE

         (A)      Call Answering

         The Manager shall earn an incentive or incur a discentive  for customer
call answering  performance on a basis that shall be mutually agreed to prior to
the beginning of the second Contract Year.
 
         (B)      Meter Reading

         For purposes of the meter reading  incentive,  "Estimated  Meter Reads"
are  defined as those  scheduled  meter reads  which were not  performed.  These
exclude  "management  estimates"  due to sustained  periods of abnormal  weather
conditions or abnormal  weather events such as hurricanes,  nor'easters,  winter
storms,  heavy snow cover,  "black ice",  flooding,  and ice storms.  When these
conditions  occur,  and it is the opinion of the Manager of Customer Offices and
the Senior Vice President of Customer Relations that meter reading effectiveness
is  diminished  by slow  travel  or  increased  safety  hazards,  the  resulting
estimates will be excluded. The Manager will record specific data concerning the
excluded estimated meter reads and the reasons for their exclusion.
 
        Management  estimates due to meter reading  personnel being assigned to
storm response efforts are also excluded.


                                       7-4


<PAGE>

         The meter reads  considered  by this  mechanism  currently are for both
electric and gas meters,  until such time as the meter reading  performance  for
electric and gas meters can be separately determined.

         The  percentage of Estimated  Meter Reads shall be calculated  for each
month by dividing the number of scheduled meter readings that are not completed,
by the total number of scheduled  meter reads.  The  Authority  shall provide an
incentive  payment  of  $200,000  to the  Manager  for each  month in which  the
percentage of Estimated Meter Reads is equal to or less than 10.9%.  The Manager
shall  neither earn an incentive  payment nor incur a  disincentive  payment for
months  during  which  Estimated  Meter  Reads  fall  between  10.9% and  11.1%,
exclusive  (the "dead band").  In months during which the Estimated  Meter Reads
are at or above 11.1 percent,  the Manager shall incur a disincentive payment of
$200,000.

         For the purpose of Section 7.2, the Minimum  Customer  Service Standard
shall be  Estimated  Meter  Reads not in excess of 11.6% in more than six months
during a year.

         (C)      Accounts Receivable

          The  Manager  shall  earn an  incentive  or incur a  disincentive  for
accounts  receivable  performance  on a basis that shall be  mutually  agreed to
prior to the beginning of the second Contract Year.

4.       PILOT PAYMENTS

                  The Authority has the sole discretion for determining  whether
to challenge  any payment in lieu of tax (PILOT)  payments  made on any Retained
Asset.  At the  Authority's  request,  the Manager shall assist the Authority in
evaluating whether to challenge any PILOT payment and with its concurrence shall
represent the Authority in any litigation challenging such


                                       7-5


<PAGE>

PILOT payment.  In the event the Manager  challenges any excessive PILOT payment
in court, any PILOT refunds received shall be shared 25%/75% between the Manager
and the  Authority,  respectively.  The  Manager  shall be  responsible  for all
litigation-related costs pertaining to such challenge,  provided,  however, that
if such litigation is terminated solely at the Authority's  request,  or if this
Agreement  expires  or is  terminated  by either  party,  the  Manager  shall be
reimbursed for all of its costs related to litigations brought at the request of
the  Authority  plus interest at the Base Interest Rate to the extent such costs
are not included in the Annual T&D Budget.

CONSTRUCTION STANDARDS
- ----------------------

         The Manager and its Subcontractors  shall perform all Construction Work
in a timely,  safe and efficient manner  consistent with the Contract  Standards
and the Major Capital Plan and Budget,  unless otherwise  directed in writing by
the Authority. In developing any design and engineering specifications,  whether
for bid documents or for its own use, the Manager shall utilize good engineering
practices and shall consult with and implement the reasonable recommendations of
the  Authority.  The Authority  shall have access to all  construction  sites in
accordance  with  Section  3.1(F)  and  shall  have  the  right  to  review  all
Construction Work on an on-going basis for, among other things,  compliance with
milestone schedules,  performance testing,  final completion and other customary
construction contract provisions. The Authority and the Manager shall also agree
to additional  procedures  or standards to be followed on a project-by-  project
basis prior to the adoption of each Major Capital Plan and Budget.

PROCUREMENT REQUIREMENTS
- ------------------------

         In conducting  any  procurements  for all or a portion of  Construction
Work,  the  Manager  shall  comply  with  Applicable  Law and shall use its best
efforts to obtain such  services or materials on a least cost basis,  subject to
the Contract  Standards.  The parties shall agree on additional  guidelines  for
such  procurements  prior to the adoption of the initial  Major Capital Plan and
Budget and from time to time  during the Term.  Any  decision  by the Manager to
perform  Construction  Work  with  its  own  workforce  rather  than by use of a
Subcontractor  shall be made with due consideration of the goal of utilizing the
lowest cost responsible party to perform such work, unless otherwise directed by
the  Authority or warranted  due to the cost,  size,  scope or  complexity  of a
particular  Major Capital  Improvement or Public Works  Improvement,  as well as
additional  provisions  to be agreed to by the parties  prior to the adoption of
the Major Capital Plan and Budget.

sufficient  to allow the Authority to verify the amounts set forth in the Annual
Settlement Statement, information concerning the performance of the Manager with
its maintenance and Construction Work  responsibilities,  any fines or penalties
incurrent to a  Governmental  Body,  and known  violations of Applicable Law and
such other matters to enable the  Authority to oversee the Manager's  compliance
with the terms of this Agreement.

         Utilizing  the FERC Uniform  System of Accounts  (USoA) as a framework,
the Manager shall prepare  proper,  accurate and complete  Direct Cost and Third
Party Costs Budgets. The Manager may establish subaccounts within the USoA prime
accounts to provide greater  detailed  descriptions of cost  activities.  Detail
shall be  sufficient  enough  to  enable  the  Authority  to  prepare  pro forma
financial  statements and financial  ratios  regarding the operations of the T&D
System.  Underlying  accounting  data shall be  maintained  to provide  adequate
support for the respective budgets.

The  format of the Direct  Cost  Budget and Third  Party  Cost  Budget  shall be
mutually  agreed to by the  Authority  and the  Manager no later than six months
prior to the anticipated Closing Date.

                           COST ALLOCATION METHODOLOGY


         The cost  allocation  methodology  described  herein shall be developed
jointly  by a team  composed  of  representatives  from  the  Authority  and the
Manager.  This team  will  recommend  a plan to  establish  the cost  allocation
procedures  to be  followed  by the  Manager in  performing  its  Operation  and
Maintenance Services and Construction Work.

         The  initial  task of this  joint  project  team  will be to  obtain  a
detailed  understanding of the nature of (1) the restructured  operations of the
Parent to determine an  appropriate  definition of the segments or recipients of
activity and related costs, (2) costs directly  incurred and (3) costs which are
or could be charged to residual overhead pools for subsequent  allocation to the
segments or recipients of activity. Upon completing this task, the joint project
team will  recommend  appropriate  allocation  methodologies  and  procedures to
charge  its  direct  costs  and  allocate  its  indirect  costs to its  internal
constituents.  Such  procedures  and  methods  will be based  on cost  causation
principles  consistent  with  generally  accepted  cost  accounting  principles.
Allocations  shall be based on cost without mark-up.  The parties recognize that
in establishing cost allocation methodologies, appropriate consideration must be
given to the NYSPSC accepted allocation methodology for the gas business and the
FERC accepted allocation methodology for the generation business.

         The objectives of the joint team will be to: (i) review LILCO's current
allocation  practices  with  regard  to costs  charged  to O&M T&D costs and T&D
capital   projects,   identify   changes  to  existing   processes   related  to
restructuring  and  develop  alternatives   appropriate  to  the  new  corporate
organization, considering prospective changes to the way the Manager will charge
its costs to the  Authority  in the  future;  (ii)  review  LILCO's  current and
proposed cost accounting systems and develop appropriate analysis techniques and
cost tracking framework; and (iii) develop budgeting and monitoring techniques.

         The joint team will  determine  the number of cost pools to be used and
prepare  a  schedule  of  cost  elements  for  the  Annual  T&D  Budget  year by
responsibility  area, FERC prime account and general ledger posting source.  For
each cost pool, the joint teams will establish an allocation  methodology.  Some
typical methodology examples used include:

services or any other activity that is unrelated, separate or distinct from this
Agreement, as expressed by its terms.

         (1) The  Manager  shall  search  for,  assess the  capabilities  of and

         responsive manner,  allowing them the opportunity to participate in the
         Contract Scope of Work.

         (2) The Manager  will  designate,  and make known to the  Authority  an
         M/WBE  Officer who will have the  responsibility  for and  authority to
         effectively administer the M/WBE Program.

         (3) The Manager shall submit its Preliminary  Subcontracting  Plan on a
         preliminary   subcontracting   plan  form,  which  shall  identify  the
         Certified  Businesses it will utilize to meet its M/WBE Contract Goals.
         Approval of any such firm is solely within the


                                      13-6


<PAGE>

         discretion of the  Authority.  The Manager will also designate an M/WBE
         Officer  who will  have  the  responsibility  for,  and  authority  to,
         effectively administer these procedures. If the Manager believes it may
         be unable to meet the Goals,  the reasons shall be submitted in writing
         with the form.

         (4) The Manager  may  inspect the current New York State  Certification

         of Minority and Women's Business Development.

         (5) Firms certified as both MBE and WBE may count toward either the MBE
         or WBE Goal on a single contract,  but not both,  regardless of whether
         either Goal is thus exceeded. The Manager must choose the Goal to which
         the   participation   value  is  to  be  applied  in  the   preliminary
         Subcontracting Plan.

         (6) Within 10 days  following  the  adoption of the initial  Annual T&D
         Budget and in any event no later than 60 days prior to the  anticipated
         Closing  Date,  the Manager shall submit a complete  Utilization  Plan,
         which  shall  include  identification  of the M/WBEs  which the Manager
         intends to use; the dollar amount of business with each such M/WBE; the

         such M/WBEs;  and the commencement  and end dates of such  performance.
         The Authority will review the plan and,  within 20 days of its receipt,
         issue a written  acceptance of the plan or comments on  deficiencies in
         the plan.

         (7) The  Authority  shall  consider a partial  or total  waiver of Goal
         requirements only upon the submission of a written request for a waiver
         following the Manager's  unsuccessful good faith efforts at compliance.
         Such waiver request may be made  simultaneously  with the submission of
         the Utilization Plan.

         (8) The Manager  shall  include in each  Subcontract,  in such a manner
         that the provisions will be binding upon each subcontractor, all of the
         provisions  herein including those requiring  subcontractors  to make a
         good faith effort to solicit participation by M/WBEs.

         (9) The Manager shall keep records,  canceled  checks and documents for
         at least one (1) year  following  completion of this  Agreement.  These
         records, and canceled checks,  documents or copies thereof will be made
         available at reasonable  times upon written request by the Authority or
         any other authorized governmental entity.

         (10) The Manager shall submit monthly  compliance reports regarding its
         M/WBE  utilization  activity on a Compliance  Report -orm acceptable to
         the Authority. Reports


                                      13-7   


<PAGE>

         are due on the first  business  day of each  month,  beginning  30 days
         after the Closing Date.

         (11) The Authority will conduct compliance reviews for determination of
         the Manager's  performance relative to meeting the specified M/WBE Goal
         which may include review and inspection of documents  pertaining to the
         Manager's efforts towards meeting the Goals and on-site interviews with
         personnel  of Manager and its  subcontractors.  The Manager  will fully
         cooperate to assist the Authority in this endeavor.

         (12) The  Manager  shall not use the  requirements  of this  section to
         discriminate against any qualified company or group of companies.

         (d) CONDITIONS FOR SATISFYING M/WBE GOALS. M/WBE  participation will be
         counted  toward the total Contract M/WBE Goals subject to the following
         conditions:

         (1) If  the  Manager  is  unable  to  meet  the  Goals  with  Certified
         Businesses by making all of the good faith efforts defined herein,  the
         Manager shall actively solicit uncertified M/WBEs to satisfy the Goals.
         Uncertified  firms  will be  required  to  submit  an  application  for
         certification   (to  the  Office  of  Minority  and  Women's   Business
         Development)  and will be counted as contributing  towards the contract
         Goals only after they have been certified.

         (2) The  Manager  must keep  records of  efforts  to utilize  certified
         M/WBE's including

                  (i)   The firm's name, address and telephone number.

                  (ii)  A description of the information provided to the M/WBE.

                  (iii) A written explanation of why an agreement with the M/WBE
                  was not obtained.

         (3) Price alone will not be an  acceptable  basis for  rejecting  M/WBE
         bids if any of the bids are reasonable.

         (4)  Geographical  limitation  in the M/WBE search is not an acceptable
         reason  for not  meeting  the M/WBE goal when  traditionally  non-local
         firms have been generally utilized.

         (5) the  Authority  reserves  the right to reject any firm as  counting
         toward  meeting  the  Manager's  M/WBE  goal if, in the  opinion of the
         Authority,   the  facts  as  to  that  firm's  business  and  technical
         organization and practices justify the rejection.


                                      13-8


<PAGE>

         (e) MANAGER'S  GOOD-FAITH  EFFORTS.  To satisfy the M/WBE participation
         requirements,  the  Manager  agrees  to make the  following  good-faith
         efforts in a timely manner:

         (1) Submission of a completed, acceptable Utilization Plan as described
         herein.

         (2) Advertising in appropriate general circulation,  trade and minority
         and women-oriented publications.

         and women- owned business enterprises listed in the Directory.

         (4)  Attendance at meetings,  if any,  scheduled by the Authority  with
         certified M/WBEs capable of performing the Contract Scope of Work.

         (5) Written notification to M/WBE trade associations located within the
         region where the Contract Scope of Work will be performed.

         (6)   Structuring   the   Contract   Scope  of  Work  for  purposes  of
         subcontracting with certified M/WBEs.

         (7) Where certified M/WBEs have expressed an interest to the Manager in
         performing work that the Manager normally performs with its own sources
         and the  Contract  Scope  of Work  has not been  fully  performed,  the
         Manager shall  consider  subcontracting  such work or portions of it to
         meet the M/WBE Goals.

1.9.  COMMENCEMENT OF ACTIONS ON STATE PUBLIC WORKS CONTRACTS.  The
time  within  which an action on this  Agreement  against  the  Manager  must be
commenced  shall be computed from the date of  completion of the physical  work.
The Manager may notify the  Authority in writing,  that such  physical  work has
been completed by specifying a completion date, which date shall be no more than
thirty days  previous to the date of such notice,  in which case the  completion
date set forth in such notice  shall be deemed to be the date of  completion  of
the physical  work unless the  Authority,  within thirty days of receipt of such
notice,  notifies the Manager in writing of its disagreement.  In the event that
the  Manager  fails to send the  notice  provided  for  herein or the  Authority
disagrees in the manner provided herein,  the date of completion of the physical
work shall be determined in any other manner provided by law.

                            ARTICLE 2 - POWER SUPPLY

2.1.     DELIVERY  OF  POWER.  During  the  Term of this  Agreement,  except  as
         otherwise provided herein, GENCO agrees to sell and Deliver to LIPA and
         LIPA agrees to purchase and accept Delivery from GENCO, as follows:

2.1.1.   CAPACITY.  GENCO will sell and  Deliver to LIPA all the  capacity  (MW)
         from the Generating Facilities in accordance with this Agreement.

         2.1.2. ENERGY. GENCO will sell and Deliver to LIPA all the energy (MWh)
it produces from the Generating  Facilities,  in accordance with this Agreement,
that LIPA  requests  to meet the  Electricity  requirements  of its  Electricity
Customers and for making Off System Sales.

2.1.3.   ANCILLARY  SERVICES.  GENCO will provide the various Ancillary Services
         as  required  by LIPA.  LIPA  will pay  GENCO in  accordance  with this
         Agreement,  for any cost  associated  with any  Ancillary  Services not

2.3.  DISPATCH OF GENERATING FACILITIES.

         (a)  LIPA  shall  have  the  responsibility  for  the  Dispatch  of the
Generating  Facilities for both real (MW) and reactive (Mvar) power requirements
for providing  Electricity to LIPA. LIPA shall also have the  responsibility for
the  Dispatch  of  Ancillary  Services  at the  Generating  Facilities  for  its
Electricity  Customers.  It is  anticipated  that  Dispatch  of  the  Generating
Facilities will be  accomplished  by LIPA through the use of existing  automatic
generator  control  equipment at the  Generating  Facilities.  If the  automatic
generator control equipment is not currently  installed at a Generating Facility
or  becomes   inoperable,   GENCO  shall  manually   implement  LIPA's  Dispatch
requirements.   Internal  combustion  units  are  not  equipped  with  automatic
generation control equipment and, therefore,  LIPA's Dispatch requirements shall
be implemented manually by GENCO.

         (b) GENCO may, in its sole  discretion  consistent with Prudent Utility
Practice,  override the automatic generation,  reactive power and load frequency
control  equipment  to  preserve  the safety  and  integrity  of its  Generating
Facilities and to react to System Emergencies and System Pre-Emergencies.

         (c) When Dispatching the Generating  Facilities,  LIPA will comply with
the  limitations  of  Dispatch as set forth in  Appendix  E,  including  but not
limited to, minimum  loadings,  ramp rates,  scheduled shut down time,  internal
combustion loadings and start-up times on the Generating Facilities.  GENCO will
inform LIPA when Prudent Utility Practice requires changes to those limitations,
either on a short term or long term basis.  Such  changes may be required due to
conditions  such as  equipment  problems  (e.g.  crack in  turbine,  build up in
precipitators),  opacity and voltage  regulation.  GENCO will  provide LIPA with
revised  limitations of Dispatch  reflecting  such changes as required,  but not
less than once per year.

         (d) LIPA will provide GENCO with a preliminary schedule of the expected
operation of the Generating  Facilities (steam units only) on a week ahead and a
day  ahead  basis.  For next  day and next  seven  (7)  days of  operation,  the
preliminary  schedule  must be provided to GENCO by 11 AM on the  previous  day.
Schedules  for  Friday and  Saturday  must be  provided  on  Thursday  by 11 AM.
Schedules  for  Sunday and Monday  must be  provided  on Friday by 11 AM. In the
event of a Legal Holiday the schedules must be provided on the last Business Day
prior to the Legal Holiday. The above scheduling requirements may be modified in
accordance  with  the  NYPP/ISO  requirements.  LIPA  will  not be bound by such
preliminary schedule and will be permitted to Dispatch the Generating Facilities
on a real time basis  consistent  with the  limitations set forth in Section 2.3
(c).

         (e) GENCO will normally  operate the  Generating  Facilities at a power
factor between 0.90 and 1.0 (lead or lag Mvar) at the Delivery  Points,  subject
to the limitations  defined in Section 2.3 (b).  Notwithstanding  the foregoing,
during a System  Emergency  or  System  Pre-Emergency,  GENCO  may  operate  the
Generating Facilities below a 0.90 power factor but not below a 0.85


                                      - 9 -


<PAGE>

power  factor  (lead  or lag  Mvar) at the  Delivery  Point(s),  subject  to the
limitations defined in Section 2.3 (b).

2.4. MAINTENANCE  SCHEDULING.  The Generating  Facilities' five year maintenance
outage  schedule  will be  provided  by  GENCO  ninety  (90)  days  prior to the
commencement  of each Contract Year.  GENCO will not schedule major  maintenance
outages in the  months of June,  July and  August,  except in the case of System
Emergency or by mutual  agreement,  or in response to unusual  circumstances  in
accordance with Prudent  Utility  Practice.  The Parties  recognize that certain
non-scheduled  routine  maintenance  will be conducted  throughout  the year, as
required,  for the purpose of inspection,  cleaning and/or repair of power plant
equipment.  GENCO will attempt to schedule and implement such outages in the off
peak periods. GENCO will inform LIPA when such maintenance is required.

2.5.  DEPENDABLE  MAXIMUM NET  CAPABILITY  (DMNC)  TESTING.  GENCO will  perform
capacity  tests on its  Generating  Facilities  to  determine  the DMNC  rating,
consistent  with the "NYPP Methods and  Procedure 2 - Uniform  Method for Rating
Generating  Capability,"  as it may be revised or replaced.  If the NYPP Methods
and Procedure -2 is revised or replaced,  the target level in the DMNC incentive
will be modified as required to reflect these  changes.  GENCO will provide LIPA
with  sufficient  advance notice of the capacity test dates and provide LIPA the
opportunity  to witness such tests.  GENCO will also provide to LIPA the results
of the DMNC tests for each individual generating unit.

2.6. DMNC TARGET.  GENCO will use reasonable efforts, in accordance with Prudent
Utility  Practice to maintain a DMNC level of 3975 MW (to be revised to be equal
to the average of annual DMNC values for the last five-year  period prior to the
Closing Date as described in Appendix F) during the Summer Operating  Period. It
is the intent of the  Parties  that the  expense  and  capital  budgets  will be
sufficient to provide GENCO a reasonable opportunity to maintain the DMNC target
level.  If LIPA should not approve an adequate  budget it is recognized that the
DMNC  target may not be  achieved.  In such  event,  the  incentive/disincentive
provisions  of the  DMNC  performance  incentive  shall  equitably  be  adjusted
consistent with Section 9.2. In addition,  this value will be reduced to reflect
any  Generating  Facility  that  has  been  Ramped  Down,  mothballed,  retired,
significantly derated, removed from service or incurs a long term outage, except
that for a  significant  derating,  removal from service or long term outage the
reduction  in the DMNC target  will apply only to the extent  that these  events
were not attributable to GENCO's failure to follow Prudent Utility Practice.

2.7. T&D SYSTEM  ACCESS.  LIPA will provide open access  service to GENCO on its
T&D System for Off System  Sales to the extent that the required T&D capacity is
available,  priced at applicable FERC tariffs or other  non-discriminatory terms
and prices.

                     ARTICLE 8 - PURCHASE PRICE AND PAYMENT
                     --------------------------------------

8.1.  PRICE  COMPONENTS.  Except  as  otherwise  specifically  provided  in this
Agreement,  the prices LIPA will pay to GENCO for Electricity delivered pursuant
to this Agreement will be those prices calculated as set forth in Appendix A and
Appendix B. During the Term of this Agreement,  LIPA will make monthly  payments
to GENCO consisting of an amount equal to: (i) the Monthly Capacity Charge, (ii)
the Monthly Variable Charge,  (iii) the Monthly Ancillary  Service Charge,  (iv)
the Monthly  Capacity  Payment  Adjustment  Charge and (v) the Monthly  Variable
Adjustment Charge.

         8.1.1.  MONTHLY CAPACITY CHARGE. The Monthly Capacity Charge is 1/12 of
the annual  Capacity  Charge as set forth in  Appendix  A. The  annual  Capacity
Charge will compensate GENCO for its fixed costs of generating  Electricity from
the Generating  Facilities  (including  associated common costs) including:  (a)
return  on  investment,  and  depreciation  for  the  undepreciated  cost of the
Generating  Facilities,  (b) completed capital additions  approved in accordance
with Article 9 including  Allowance for Funds Used During  Construction  (AFUDC)
(c) insurance,  (d) income taxes  (federal,  state,  local,  net or gross),  (e)
property  and all other  taxes,  (f) fixed  operations  and  maintenance  costs,
including an allowance  for  scheduled  major  maintenance  and  overhauls,  (g)
research and development costs and (h) administration costs.  Generation charges
will not be increased as a result of any step-up in the book or tax basis of the
assets. In establishing the depreciation  schedule for the recovery of the costs
of existing plant


                                     - 13 -


<PAGE>

and  approved  capital  additions  thereto,   the  Parties  will  commission  an
engineering and economic  depreciation study which reflects the age,  condition,
and market  circumstances  which  influence the remaining  economic lives of the
Generating Facilities. The results of such depreciation study will be taken into
account  in  determining   the  proper   depreciation   schedule  and  resulting
depreciation charges to be included in the filing of the FERC regulated Capacity
Charge  component  of the formula  rate  described in this Article 8. The annual
Capacity Charge will exclude demolition costs,  environmental  remediation costs
related to demolition and site restoration  costs in excess of amounts recovered
in GENCO's  retail rates  applicable  as of March 1997 and  recovered as part of
GENCO's  depreciation  charge, and charges for starts,  fired hours of operation
and fuel swaps as  defined in  Appendix B after  meeting  the  threshold  levels
established in Appendix B.

         8.1.2.  MONTHLY  VARIABLE  CHARGE.  The Monthly Variable Charge will be
based on the variable  operation and maintenance  costs as set forth in Appendix
A, multiplied by the actual MWh of operation of the Generating  Facilities.  The
variable  operation and maintenance costs include those materials,  supplies and
maintenance costs, environmental fees or charges, and labor costs, if any, which
vary  directly  with the  amount of energy  generated.  Variable  operation  and
maintenance  costs do not include  charges for fixed  operation and  maintenance
costs nor charges for starts, fired hours of operation and fuel swaps defined in
Appendix B after  meeting  threshold  levels  established  in  Appendix  B. Fuel
required  to operate the  Generating  Facilities  for the  purpose of  providing
energy  will be  provided  in  accordance  with  the  provisions  of the  Energy
Management Agreement and, accordingly, there will be no charge for fuel.

         8.1.3.  MONTHLY ANCILLARY  SERVICE CHARGE.  LIPA will pay for any costs
incurred by GENCO in providing  Ancillary Services to LIPA, if any such services
are  required by LIPA which are not  otherwise  compensated  by LIPA through the
Monthly Capacity Charge or the Monthly Variable Charge or otherwise, such charge
defined as the "Monthly  Ancillary  Service  Charge." Fuel, if any,  required to
operate  the  Generating  Facilities  for the  purpose  of  providing  Ancillary
Services  will be  provided  in  accordance  with the  provisions  of the Energy
Management Agreement and, accordingly, there will be no charge for fuel.

         8.1.4. MONTHLY CAPACITY PAYMENT ADJUSTMENT CHARGE. The Monthly Capacity
Payment  Adjustment  Charge  will  provide  for the  payment by LIPA to GENCO of
non-variable related expenses net of insurance proceeds, that can not be planned
for  with  any  certainty  and are  outside  the  control  of  GENCO,  including
extraordinary  uninsured damage from storms and other acts of God,  catastrophic
failure  of one or  more  units  of a  Generating  Facility,  and  environmental
compliance  (for events  that were not planned for and not of a type  covered by
any   contingency  in  the  applicable   budget),   provided  that  all  capital
expenditures  are  subject to  approval  by LIPA as  provided  in  Article  9.4.
Incremental  costs associated with the retirement of a Generating  Facility,  as
set forth in Section  8.3, or through a Ramp-Down  of a  Generating  Facility in
accordance with Article 11 of this Agreement may also be included in the Monthly
Capacity Payment Adjustment Clause.

<PAGE>

         8.1.5. MONTHLY VARIABLE PAYMENT ADJUSTMENT CHARGE. The Monthly Variable
Payment Adjustment Charge will provide for the payment of starts, fired hours of
operation,  and fuel swaps  defined in Appendix B after  meeting  the  threshold
levels  established in Appendix B. Charges  incurred for starts,  fired hours of
operation and swaps after  meeting the threshold  levels will be billed in total
to LIPA by GENCO  immediately  following the month  incurred in accordance  with
Section 8.5.

         8.1.6.  NOX  AND  SOX  EMISSION  CREDITS.  GENCO  shall  apply  to  the
Generating Facilities all NOx, SOx and other air emission credits owned by GENCO
or attributable to the Generating Facilities, the cost of which to LIPA shall be
included at cost  without  markup in the Monthly  Capacity  Charge to the extent
such costs are fixed costs and in the Monthly Variable Charge to the extent such
costs vary with levels of generation.  Sixty-seven  percent (67%) of any sale or
other  disposition  of  emission  credits  which are  excess to the needs of the
operation of the Generating  Facilities  shall be credited to the annual charges
to LIPA under the Agreements.  GENCO will receive  thirty-three percent (33%) of
the net proceeds of any such sale or  disposition  of emission  credits.  Parent
shall provide LIPA with notice of its intention to sell or otherwise  dispose of
emission credits in order to allow LIPA sufficient time to submit a bid for such
credit, if it so chooses.

8.2.  POWER PLANT  ELECTRIC USE. It is recognized and agreed that the Generating
Facilities require electricity for operating auxiliary systems. This electricity
shall be provided by the specific  generating  units located at the  appropriate
Generating  Facilities  and/or from LIPA's T&D System.  Any charges from LIPA to
GENCO for this auxiliary power from LIPA's T&D System,  will be charged to GENCO
at non-discriminatory  rates, and such charges will be added, without any markup
thereto, to the Monthly Variable Charge.

8.3.  GENERATING  FACILITY MAJOR  FAILURE.  LIPA and GENCO may mutually agree to
cease  operating  any  Generating  Facility,  due to a  major  failure  of  such
Generating  Facility  that the Parties  mutually  agree is uneconomic to repair.
Upon mutual agreement, the Parties may elect to either mothball or retire such a
Generating Facility.

In the event the Parties mutually agree to mothball such a Generating  Facility,
with or without  preserving the  operability of such Generating  Facility,  LIPA
will continue to pay the associated  Capacity  Charge which will reflect any net
cost reduction achieved from the mothballing of such Generating Facility.

In the event the Parties  mutually  agree that a Generating  Facility  should be
retired and  decommissioned,  LIPA will pay GENCO the remaining  unrecovered net
plant cost of such  Generating  Facility,  including any  unreimbursed  approved
capital  expenditures  that have been made and  reasonably  incurred  demolition
costs,  site restoration costs and any other costs associated with retiring such
Generating  Facility net of site  restoration  costs recovered in rates together
with  accumulated  interest on reserves  carried by Long Island Lighting Company
for such  site  restoration  costs,  if any,  over  the life of such  Generating
Facility. LIPA will have the option


                                     - 15 -


<PAGE>

to make such payment to GENCO immediately  following the decision to retire such
Generating  Facility or agree to a payment  schedule over the remaining  term of
the Agreement,  including interest through an adjustment to the Monthly Capacity
Payment Adjustment Clause.

8.4. INCENTIVES/DISINCENTIVES.  The incentive/disincentive payments contemplated
by Appendix F in this Agreement will be calculated  and billed  separately  from
the charges established in Appendix A and B no less frequently than annually.

8.5.  PAYMENT.  GENCO  will  submit a monthly  invoice  to LIPA for the  Monthly
Capacity  Charge  by the first  (1st)  Business  Day of the  month for  capacity
provided during the month,  consistent with the provisions in Section 8.1. GENCO
will also submit monthly invoices to LIPA for the Monthly  Variable Charge,  and
any other charges that may be required,  consistent  with this Article 8, by the
fifth (5th)  Business Day  following the month of service,  consistent  with the
provisions  in this Article.  Payment of the Monthly  Capacity  Charge  invoiced
amounts  shall  be due and  payable  by LIPA on the  later of the  tenth  (10th)
Business Day of the month or ten (10) Business Days after LIPA's  receipt of the
monthly invoice. Payment of the Monthly Variable Charge invoiced amounts and any
other  invoices  shall be due and  payable  by LIPA on the  later  of the  first
Business Day following the  nineteenth  (19th) of the month or ten (10) Business
Days of LIPA's receipt of such invoices.

All such payments  shall be made in the form of immediately  available  funds by
wire transfer to a bank or financial  institution  specified by GENCO or in such
other form as may be  reasonably  requested  by GENCO.  The wired  funds will be
deemed  timely  paid if  received  by the close of business on or before the due
date of such payment.

8.6 LATE PAYMENT. Any invoiced amount not paid by LIPA by the due date will bear
interest at the Base Interest Rate.


                               ARTICLE 9 - BUDGETS
                               -------------------

9.1.  BUDGET PREPARATION.

         9.1.1.  INITIAL  CAPACITY AND VARIABLE CHARGE  DETERMINATION.  Not less
than a mutually agreed upon number of days prior to (a) the Closing Date and (b)
the commencement of each successive five year period  thereafter during the Term
of this  Agreement,  GENCO  shall  prepare  and  submit to LIPA for  review  and
approval a proposed Five Year Budget Plan,  which shall  provide  details on the
fixed and variable costs of operating the GENCO  Generating  Facilities,  as set
forth in Sections  8.1.1 and 8.1.2 and as  described  by Appendix A. The initial
such budget,  upon approval by LIPA, shall establish the Monthly Capacity Charge
and Monthly  Variable  Charge for the first year of the five year period,  which
forms the basis for adjustment  for  subsequent  Contract Years in the five year
period in  accordance  with  Appendix A. The budget plan for the first  Contract
Year of the first Five Year Budget Plan will be based upon the agreed


                                     - 16 -


<PAGE>

upon   disaggregated   generation  cost  elements  relating  to  the  Generating
Facilities  (including  associated  common  costs) and contained in the proposed
1997 rate year budget in the GENCO 1996 rate case filing with the New York State
Public Service Commission, updated for known changes in facts and circumstances,
adjusted to the First  Contract Year and as set forth in Appendix A. Such budget
shall  also  consider  actual  historical   results  prepared  on  a  comparable
disaggregated  basis for 1996 and  thereafter up to the date of adoption of such
budget.  For subsequent  Contract Years the Monthly  Capacity Charge and Monthly
Variable  Charge will be based upon the previous  year as adjusted in accordance
with indices and approved capital  improvement  budgets as set forth in Appendix
A.

         9.1.2.  FIVE YEAR CAPITAL  IMPROVEMENT  BUDGETS.  GENCO shall  annually
prepare and submit to LIPA a rolling  Five Year Capital  Improvement  Budget for
incremental  capital  expenditures  and associated  rate  adjustments for LIPA's
review and approval. Each Five Year Budget Plan shall consist of five individual
Contract Year Budget Plans.

9.2.  BUDGET  REVIEW.  Not more  than a  mutually  agreed  upon  number  of days
subsequent  to LIPA's  receipt of the  proposed  Five Year  Budget  Plan  and/or
rolling  Five Year Capital  Improvement  Budget from GENCO,  LIPA shall  provide
GENCO with any requested changes,  additions,  deletions or revisions. The GENCO
Representative and LIPA  Representative  will employ reasonable efforts to agree
upon a final Five Year  Capital  Improvement  Budget by a mutually  agreed  upon
number of days  before the  commencement  of the  initial  Contract  Year and to
approve the first year of the rolling  Five Year  Capital  Improvement  Budget a
mutually  agreed upon number of days prior to the  commencement of each Contract
Year.  Such  approved  budget for the initial  Contract  Year (a "Contract  Year
Budget")  shall  be  effective   throughout   the  Contract  Year,   subject  to
modifications  as provided in Section  9.4. It is the intent of the Parties that
the amounts  provided in the Five Year Budget Plan and rolling Five Year Capital
Improvement Plan for operation and maintenance expenses and capital expenditures
will be sufficient to provide  GENCO (or its  affiliate,  as the case may be) no
less of an opportunity to maintain the DMNC,  Availability  and Heat Rate target
levels  (as  defined in  Appendix  F) than  GENCO has at the  execution  of this
Agreement,  and to otherwise maintain the Generating  Facilities in good working
order, consistent with Prudent Utility Practices,  provided that LIPA shall have
the final right to determine  whether GENCO should proceed with specific capital
projects.  In the event that LIPA does not  approve  amounts for  operating  and
maintenance  expenses  and  capital  expenditures  that  provide  GENCO  (or its
affiliate,  as the case may be) with the same  opportunity to maintain the DMNC,
Availability and Heat Rate target levels (as defined in Appendix F) as GENCO has
at the  execution  of this  Agreement,  such target  levels  shall be  equitably
adjusted.

9.3 FAILURE TO ADOPT  CONTRACT  YEAR BUDGET.  If the Parties are unable to reach
agreement  concerning  all or any  portion of the  Contract  Year Budget for the
initial  Contract  Year of a Contract  Year Budget Plan or the first year of the
Five Year Capital  Improvement  Budget as  contemplated  in Section  9.2,  those
portions of the Contract  Year Budget that are in dispute for such Contract Year
shall be  resolved  in a  proceeding  before  the FERC.  Those  portions  of the
Contract Year Budget not in dispute shall become effective.

9.4. CAPITAL  IMPROVEMENT BUDGET  PERFORMANCE.  GENCO will provide to LIPA, on a
quarterly basis, a report of actual total capital  improvement  costs versus the
approved capital expenditures in the Five Year Capital Improvement Budget. GENCO
will prepare a detailed  explanation  outlining variations of more than ten (10)
percent  and one  million  dollars  ($1,000,000)  from  the  Five  Year  Capital
Improvement Budget.  GENCO will promptly notify LIPA when an event occurs, or is
anticipated  to occur,  which would  result in any required  unbudgeted  capital
expenditures.  As soon as  practical,  GENCO  will  provide an  explanation  and
estimate  of such  unforeseen  incremental  costs,  as well  as a  proposal  for
modification  of the applicable  Monthly  Capacity Charge to recover such costs.
LIPA  will  review  and  respond  to  such   explanation   and  Capacity  Charge
modification  proposal within thirty (30) days after receipt. If the parties are
unable  to reach  agreement,  this  dispute  shall be  resolved  by a final  and
non-appealable order of FERC in a proceeding under the Federal Power Act.


                      ARTICLE 10 - INCENTIVES/DISINCENTIVES
                      -------------------------------------

10.1.  INCENTIVES/DISINCENTIVES.  Four performance  incentives/disincentives are
established under this Agreement:  DMNC,  Availability,  Heat Rate, and Property
Taxes.  Each of  these  incentives/disincentives  mechanisms  are set  forth  in
Appendix F.


                         ARTICLE 11 - CAPACITY RAMP DOWN
                         -------------------------------

11.1. CAPACITY RAMP DOWN OPTION.  Beginning in Year Seven, LIPA may determine to
reduce ("Ramp  Down") the amount of capacity  purchased  from GENCO.  In such an
event,  LIPA shall  immediately  reimburse GENCO for the Capacity Charges in the
amount  set forth  below  which  would  have been  recovered  from LIPA over the
remaining portion of the original term of this Agreement.

The Ramp Down will be an aggregate potential reduction amount of no greater than
1500 MW. The Ramp Down schedule is as follows:

If economic  conditions  change during the term of this Agreement,  the order of
the above  Ramp Down  schedule  may be changed if  mutually  agreed  upon by the
Parties.  The Ramp Down amount  shall be for the full amount of the  capacity in
each agreed upon capacity block as set forth above.

If LIPA exercises this option in years 7 through 10 of this Agreement, LIPA will
immediately  pay GENCO 100  percent of the present  value,  at the time the Ramp
Down option is exercised,  of all the related  Capacity  Charges,  that it would
have  otherwise  received for that  capacity  block of unit(s)  which was ramped
down, for the remainder of the term of this Agreement,  adjusted for the removal
of net salvage as used in the depreciation  calculation.  GENCO will be entitled
to  these  payments  regardless  of the  future  disposition  of the  Generating
Facilities.  GENCO will have the  responsibility  for all costs for  demolition,
environmental remediation and site restoration.


If LIPA exercises this option in subsequent years, the recovery  percentage will
be  reduced  for  such  capacity  block(s)  through  the end of the term of this
Agreement as follows:

If LIPA exercises this option,  GENCO will be entitled to the fixed cost reduced
by the above  percentages  regardless of the future  disposition of any released
capacity.  The present value will be determined  using GENCO's  weighted cost of
capital used in the Capacity Charge to LIPA.

GENCO may use any capacity  released  pursuant to this option to bid on new LIPA
capacity  requirements or on LIPA's capacity  requirements to replace other Ramp
Down capacity. If GENCO wins such bid, it will be paid its bid price.

If GENCO  continues to operate the ramped down unit,  GENCO will use  reasonable
efforts to market the released  capacity.  Allocation of profits from Off System

The profits for any capacity sales from such Ramp Down capacity will be based on
all costs  required for such sale that have not been  recovered  by GENCO.  Such
recovery is understood to include any prepayment by LIPA of fixed O&M costs.  If
LIPA's  exercise  of  this  option  results  in  operational  inefficiencies  at
Northport,  the Capacity Charges will be adjusted to reflect  demonstrable  cost
increases due to such inefficiencies.


                        ARTICLE 12 - TERM AND TERMINATION
                        ---------------------------------

12.1.  TERM. The Term of this Agreement  shall commence on the Closing Date and,
except as provided in Article 4 and as otherwise  provided herein,  shall remain
in full force and effect  for an  initial  term of fifteen  (15) years from such
Closing  Date.  At the end of the Term of this  Agreement,  LIPA may renew  this
Agreement,  for all  capacity  upon  which it has not  exercised  its Ramp  Down
option,  under  substantially the same terms and conditions as set forth herein,
including  but not  limited  to the  continuation  of a Ramp Down  option.  This
Agreement  (other  than  Article 4) shall  terminate  upon the  purchase  of the
Generating  Facilities by LIPA under the  Generation  Purchase  Right  Agreement
attached as Exhibit D to the Merger Agreement.

12.2.  TERMINATION  FOR CAUSE BY GENCO.  GENCO shall have the right to terminate
this Agreement for cause after an Event of Default determined in accordance with
the provisions of this Section 12.2 shall have occurred.

<PAGE>

         12.2.1  EVENTS OF LIPA DEFAULT  DEFINED.  Each of the  following  shall
constitute  an Event of  Default  on the part of the LIPA for  which  GENCO  may
terminate this Agreement upon compliance with the notice and cure provisions set
forth below:

                  (1)  Failure to Pay.  The  failure  of LIPA to pay  undisputed
         amounts  owed to GENCO  under  this  Agreement  within  90 days of such
         amounts having become due.

                  (2) Failure to Comply with  Agreement.  The failure or refusal
         by LIPA  substantially  to perform any material  obligation  under this
         Agreement  unless such  failure or refusal is excused by Force  Majeure
         except that no such failure or refusal to pay or perform in clauses (1)
         and (2) of this Section  12.2(A)  shall  constitute an Event of Default
         giving GENCO the right to terminate this Agreement for cause under this
         Section unless:

                           (a)  GENCO  has given  prior  written  notice to LIPA
                  stating that a specified  failure or refusal to perform exists
                  which will, unless corrected,  constitute a material breach of
                  this  Agreement  on the part of LIPA and  which  will,  in its
                  opinion,  give GENCO a right to terminate  this  Agreement for
                  cause  under this  Section  unless such  default is  corrected
                  within a reasonable period of time, and

                           (b) LIPA has  neither  challenged  in an  appropriate
                  forum  GENCO's  conclusion  that such  failure  or  refusal to
                  perform has occurred or constitutes a material  breach of this
                  Agreement nor  corrected or diligently  taken steps to correct
                  such default  within a reasonable  period of time but not more
                  than 60 days from the date of the  notice  given  pursuant  to
                  clause  (a)  of  this  subsection  (but  if  LIPA  shall  have
                  diligently  taken  steps  to  correct  such  default  within a
                  reasonable  period of time,  the same shall not  constitute an
                  Event of  Default  for as long as LIPA is  continuing  to take
                  such steps to correct such default).

12.3. TERMINATION FOR CAUSE BY LIPA. LIPA shall have the right to terminate this
Agreement for cause after an Event of Default  determined in accordance with the
provisions of this Section 12.3 shall have occurred.

         12.3.1  EVENTS OF GENCO  DEFAULT  DEFINED.  (1) Events of  Default  Not
Requiring  Cure  Opportunity  for  Termination.  Each  of  the  following  shall
constitute an Event of Default on the part of GENCO for which LIPA may terminate
this Agreement without any requirement of cure opportunity:

                  (a) Change of Control of GENCO.  Change of Control of GENCO or
         the Guarantor has occurred;  provided,  however,  that the  combination
         effectuated under the Merger Agreement shall not constitute a Change of
         Control of GENCO for purposes of this provision.

                  (b) Voluntary  Bankruptcy.  The written  admission by GENCO or
         the  Guarantor  that it is  bankrupt,  or the  filing  by  GENCO or the
         Guarantor of a voluntary petition under the Federal Bankruptcy Code, or
         the consent by GENCO or the Guarantor to the  appointment by a court of
         a receiver or trustee for all or a substantial  portion of its property
         or business, or the making by GENCO or the Guarantor of any arrangement
         with or for the benefit to its  creditors  involving an assignment to a
         trustee,  receiver or similar fiduciary,  regardless of how designated,
         of all or a substantial portion of GENCO's or the Guarantor's  property
         or business.

                  (c) Involuntary Bankruptcy. The final adjudication of GENCO or
         the Guarantor as bankrupt after the filing of an  involuntary  petition
         under the Federal  Bankruptcy Code, but no such  adjudication  shall be
         regarded  as  final  unless  and  until  the  same is no  longer  being
         contested  by  GENCO  or the  Guarantor  nor  until  the  order  of the
         adjudication shall be regarded as final unless and until the same is no
         longer being contested by GENCO or the Guarantor nor until the order of
         the adjudication is no longer appealable.

                  (d) Credit Enhancement.  Failure of GENCO to supply, maintain,
         renew, extend or replace the credit enhancement  required under Article
         18 hereof in the event there is a Material  Decline in the  Guarantor's

without  waiting for the  expiration of the  applicable  time period.  Except as
provided in subsection  12.5(D)  hereof  relating to provisional  remedies,  the
Arbitrators  shall decide all aspects of any dispute  brought to them  including
attorney disqualification and the timeliness of the making of any claim.

         (d)  Provisional  Relief.  Either party may,  without  prejudice to any
negotiation,  mediation,  or  arbitration  procedures,  proceed  in any court to
obtain provisional judicial relief if, in the such party's sole discretion, such
action is necessary to avoid imminent irreparable harm, to provide uninterrupted
electrical  and other  services,  or to  preserve  the  status quo  pending  the
conclusion of the dispute procedures specified in this Section.

         (e) Awards.  The Arbitrators  shall have no authority to award punitive
damages  or any other  damages  aside  from the  prevailing  party's  actual and
consequential damages plus interest at the Base Interest Rate from the date such
damages were incurred.  The Arbitrators shall not have the authority to make any
ruling,  finding,  or award that does not conform to the terms and conditions of
this Agreement. The Arbitrators may award reasonble attorneys' fees and costs of
the  arbitration.  The  Arbitrator's  award shall be in writing and shall be set
forth the factual and legal bases for the award.

                  (b) If LIPA's Metering Equipment has not been installed, or if
it is found to be inaccurate, then the Parties shall jointly prepare an estimate
of the correct  reading on the basis of  available  information,  including  the
assumption that if the duration of the metering inaccuracy cannot be determined,
such duration  shall be deemed to have  persisted for fifty percent (50%) of the
time between the last meter reading and the discovery of the inaccuracy.

14.3. OIL FUEL MEASUREMENT.  GENCO will perform monthly Fuel oil tank gauging to
determine  the amount of No. 6 Fuel oil,  No. 2 Fuel oil and kerosene in storage
at each Generating  Facility.  The gauging will occur on a  pre-determined  date
prior to the end of the  month.  Usage  from the  gauging  date  until  the last
calendar day of the month will be calculated  based on the average  monthly Heat
Rate at each Generating  Facility and the actual generation  between the gauging
date and the end of such month.  This calculated  amount will be subtracted from
the oil in storage on the  gauging  day to  determine  the oil in storage on the
last day of the month. Fuel oil deliveries during each month will be measured at
the time of delivery. The difference between the oil in storage at the beginning
and end of the month  will be added to the oil  deliveries  received  during the
month to calculate the net oil consumed for the month,  in  accordance  with the
current  methodology of calculating  Generating  Facility Fuel oil  consumption.
Changes in unit operation may necessitate  mutually agreed to  modifications  to
this procedure.

Standing"  shall  be  deemed  to have  occurred  if (1) in the  event  that  the
Guarantor has long-term senior debt  outstanding  which has a credit rating by a
Rating  Service,  such rating by a Rating  Service is  established or is reduced
below  investment  grade level or (2) in the event the  Guarantor  does not have
long-term senior debt outstanding which has a credit rating by a Rating Service,
and the Guarantor has a credit rating by a Rating Service, such credit rating is
established  or reduced below  investment  grade level,  or (3) in the event the
Guarantor does not have  long-term  senior debt  outstanding  which has a credit
rating by a Rating  Service and the Guarantor does not have a credit rating by a
Rating Service,  in which event the Guarantor shall seek a credit rating for the
Guaranty from a Rating  Service,  such rating is established or is reduced below
investment grade level or if no rating is established.  GENCO  immediately shall
notify LIPA of any Material Decline in the Guarantor's Credit Standing.

         18.1.3.  CREDIT ENHANCEMENT.  If, at any time during the Term hereof, a
Material  Decline  in  the  Guarantor's  Credit  Standing  occurs,  GENCO  shall
immediately notify LIPA's Representative  thereof and, within 30 days after such
occurrence, shall provide credit enhancement of its obligations hereunder at its
sole cost and expense in the form either of (1) an  unconditional  guarantee  of
all of  GENCO's  obligations  hereunder,  the  Manager's  obligations  under the
Management  Services Agreement,  and the Energy Manager's  obligations under the
Energy Management  Agreement provided by a corporation or financial  institution
whose long-term  senior debt is or would be rated  investment  grade by a Rating
Service or (2) an  irrevocable  letter of credit  securing  GENCO's  obligations
hereunder,  the Manager's  obligations under the Management  Services Agreement,
and the Energy Manager's  obligations under the Energy Management Agreement in a
face amount of $60,000,000  provided by a financial  institution whose long-term
senior debt is rated  investment grade by a Rating Service;  provided,  however,
that if any such  letter of credit is drawn upon in the  aggregate  in an amount
equal to 50% of the face value of such letter of credit,  GENCO shall, within 30
days thereafter,  supplement or replace such letter of credit with an additional
letter of  credit  such that the  total  amount  of such  letter of credit  then
available  equals  $60  million.  The amount of such  letter of credit  shall be
reduced by $30 million if the Energy  Management  Agreement has theretofore been
or is  thereafter  terminated  and by $26  million  if the  Management  Services
Agreement has theretofore been or is thereafter  terminated,  such obligation to
continue until the expiration or termination of this  Agreement,  the Management
Services Agreement and the Energy Management Agreement.

                                    the customers of the T&D System,

                           provided,   however,   that   GENCO   shall   not  be
                           responsible  and liable to LIPA under this  clause b)

                  (d)      due to an event which would otherwise permit recovery
                           of a  cost  under  Section  8.1.4  (Monthly  Capacity
                           Payment  Adjustment  Charge)  of  an  excess  capital

other Party  during  negotiations  with any  Financing  Party and will  promptly
execute any reasonable  amendment or addition to this Agreement  required by any

in any respect.

21.5.  FORCE MAJEURE.

         21.5.1.  EVENTS  CONSTITUTING FORCE MAJEURE. As used in this Agreement,
Force Majeure means any act, event, or condition that causes delay in or failure
of performance of obligations under this Agreement,  or otherwise materially and
adversely affects a party's ability to perform,  if such act, event or condition
(i) is beyond the reasonable  control of the party relying thereon,  (ii) is not
the result of the willful misconduct or negligent act or omission of such party,
and (iii) is not an act,  event or condition,  the risk or  consequence of which
such party expressly assumed under this Agreement, including but not limited to:

                  (1) acts of God, accident,  flood,  sabotage,  fire, epidemic,

people, civil disturbance or similar occurrence;

                  (2) entry of an injunctive or restraining order or judgment of
any Governmental  Authority,  if such order or judgment is not the result of the
act, or failure to act, of a party or its subcontractors or suppliers; or

                  (3) suspension,  termination,  interruption  of, or failure to
obtain any permit  required or  necessary  for the  construction,  operation  or
maintenance of the Generating Facilities, provided such suspension, termination,
interruption  or failure is not the result of the action or  inaction of a party
relying thereon or its subcontractors or suppliers.

         Notwithstanding  the foregoing,  neither the failure of a subcontractor
or supplier to perform its  obligations  to LIPA or GENCO,  which failure is not
itself  caused by a Force Majeure  event with respect to such  subcontractor  or
supplier,   nor  financial   difficulty   suffered  by  LIPA  or  GENCO  or  any
subcontractor, supplier or vendor in performing its obligations, shall be deemed
a Force Majeure event.

         21.5.2.  EVENT OF FORCE MAJEURE.  Except for the  obligations of either
party to make payments of amounts due to the other party,  either party shall be
excused from performance and shall not be considered to be in default in respect
of any  obligation  under  this  Agreement  to the  extent  that  a  failure  of
performance of such obligation shall be due to Force Majeure.  If either party's
ability to perform its  obligations  under this Agreement is affected by a Force
Majeure,  the party claiming such inability shall: (i) promptly notify the other
party of such Force Majeure and its cause and confirm the same in writing within
five Business Days of discovery of the event


                                     - 34 -

available  information  about the event or circumstances  constituting the Force
Majeure and the cause thereof as is reasonably requested by the other party; and
(iii)  immediately  initiate  removal of the cause of the Force  Majeure  or, if
immediate removal is not possible, to mitigate the effect thereof.

         21.5.3.  SCOPE.  The suspension of  performance  due to a Force Majeure
shall  be of no  greater  scope  and no  longer  duration  than  that  which  is
necessary. The excused party shall use its reasonable best efforts to remedy its
inability to perform.

21.6.  AMENDMENTS.  No amendments or  modifications  of this Agreement  shall be
valid unless evidenced in writing and signed by duly authorized  representatives
of both Parties.

21.7. NO WAIVER. It is understood and agreed that any delay,  waiver or omission
by GENCO or LIPA to  exercise  any right  arising  from any breach or default by
GENCO or LIPA with respect to any of the terms, provisions, or covenants of this
Agreement  shall not be construed  to be a waiver by GENCO or LIPA,  as the case
may be,  of any  subsequent  breach  or  default  of the  same or  other  terms,
provisions or covenants on the part of the other party.

21.8. NOTICES.  Any written notice under this Agreement shall be deemed properly

21.13.  NON-RECOURSE.  Except as otherwise agreed,  neither party shall have any
recourse  against any parent,  affiliate,  or constituent of the other party, or
the   successors   and  assigns  of  such  parent,   affiliate  or   constituent
(collectively, "Party Affiliates") and each party expressly waives its rights of
recourse  against,  and  releases  from  liability,   the  other  party's  Party
Affiliates.  Each party  shall look  solely to the other  party,  and the assets
thereof, to effect recovery of such party's claims against the other party.

21.14. SEVERABILITY. The invalidity or unenforceability of any provision of this
Agreement shall be determined only by a court of competent jurisdiction, and the
Parties  hereby agree to negotiate  an  equitable  adjustment  to the invalid or
unenforceable  provisions  with a view  toward  effecting  the  purposes of this
Agreement;  the  validity  or  enforceability  of the  remaining  provisions  or
portions or applications thereof, shall not be affected thereby.

21.15. RULES OF INTERPRETATION. The terms and provisions of this Agreement shall
be interpreted and construed as follows: (a) words of the masculine gender shall
include  corresponding  words of the feminine or neuter  genders and vice versa;
(b) the plural shall include the singular and vice versa; (c) unless the context
indicates otherwise,  all references herein to Articles,  Sections,  paragraphs,
exhibits,  schedules, and Appendices shall refer, respectively, to the Articles,
Sections, paragraphs,  exhibits, schedules and Appendices of this Agreement; (d)
the words "includes" or "including" mean "including, but not limited to" and are
not  limiting;  (e) any  reference  to an  agreement,  a  contract  or any other
document means the same as it may be amended, modified, supplemented or replaced
from time to time,  unless  otherwise  noted;  and (f) any reference to a Person
includes such Person's successors and assigns.

21.16.  PROPERTY TAXES.  After the Contract Date, GENCO, in its sole discretion,
may  challenge  any property tax  assessment  on its  Generating  Facilities  or
Generating  Facility  Sites  only  if  the  assessment  on any  such  challenged
facilities  is increased  not in an  appropriate  proportion  to the increase in
value related to taxable capital additions affixed to the tax parcel between the
last two tax status  dates.  If the tax  attributable  to the  assessment on the
Generating  Facilities  or  Generating  Facilities  Sites is not included in the
costs paid by LIPA or its Affiliates  (e.g.,  gas facility located on Generating
Facility Site) then GENCO, in its sole discretion,  may pursue tax challenges on
such  assessments.  This  provision  shall expire upon the  termination  of this
Agreement.

In the event GENCO challenges any tax assessments on its Generating  Facilities,
any tax  refunds  received by GENCO shall be shared  25%/75%  between  GENCO and
LIPA,  respectively.  GENCO shall be responsible for all preparatory efforts and
litigation-related  costs pertaining to any such challenge, and such costs shall
not be included in any charge under Article 8 or otherwise under this Agreement.
This provision shall expire upon the termination of this Agreement,  except that
LIPA will continue to share 75% of tax refunds  received after such  termination
to the extent  that such  refunds  relate to  property  taxes for which LIPA has
reimbursed GENCO under Section 8.1.1.

compliance with the provisions of Section 21.3 hereof.

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


I.  DMNC INCENTIVE/DISINCENTIVES

GENCO  will use its best  efforts to  maintain  its  generating  units such that
during the six month Summer  Operating  Period (May  through  October) the total
dependable  maximum net  capability  ("Annual  DMNC") as defined by the New York
Power  Pool  (NYPP)  Methods &  Procedures  - 2  (MP-2),  meets or  exceeds  the
predetermined level ("Target DMNC").  GENCO shall determine the Annual DMNC each
year in  accordance  with the New York Power Pool  Methods  and  Procedures  - 2
("MP-2").  The MP-2 test will be conducted once between June 1 through September
15 for each unit.  LIPA shall have the right to witness such tests and/or review
the test data and results. If the MP-2 is revised by the NYPP, the Parties agree
to revise or replace  this  incentive/disincentive  mechanism  in a manner  that
reflects the intended purpose.

The Annual DMNC and the Target DMNC  ratings  shall be  considered  only for the
total  system (the sum of all steam and  internal  combustion  generating  units
under contract to LIPA).

The Target  DMNC shall be  computed  as the  simple  average of the Annual  DMNC
values (as  adjusted for the average  temperature  for the last five year period
prior to the Closing  Date) for the last  five-year  period prior to the Closing
Date. The Target DMNC is based upon all of the existing GENCO steam and internal
combustion units in service.  The Target DMNC shall remain fixed unless (a) LIPA
exercises its option to ramp down its GENCO capacity purchases, or (b) any GENCO
unit is mothballed,  retired,  significantly derated, incurs a long-term outage,
or is otherwise  removed from service in whole,  or in part,  or (c) any capital
improvement  approved  by  LIPA  that  materially  increases  the  DMNC  of  the
Generating  Facilities.  Under  these  conditions,  the  Target  DMNC  shall  be
equitably   adjusted  based  on  the  generating  unit  data  for  the  original
computation period with appropriate  adjustments for the new conditions,  except
that for a  significant  derating,  removal from service or long term outage the
reduction  in the DMNC target  will apply only to the extent  that these  events
were not attributable to GENCO's failure to follow Prudent Utility Practice.

Should  the  Annual  DMNC be in excess of the  Target  DMNC,  LIPA  shall make a
payment to GENCO  equal to $30,000  per MW above that  Target  DMNC.  Should the
Annual DMNC be less than 99% of the Target  DMNC,  GENCO shall make a payment to
LIPA equal to $30,000 for each MW deficiency below 99% of the Target DMNC. There
shall not be any  incentives or  disincentives  payments for a year in which the
Annual  DMNC  is  between  99%  and  100%  of  the  Target  DMNC.   The  maximum
incentive/disincentives will be $1 million annually.

In the event that LIPA does not approve  amounts for operating  and  maintenance
expenses and capital  expenditure,  that provide GENCO with the same opportunity
to  maintain  the DMNC  target  levels  as GENCO  has at the  execution  of this
Agreement, such target levels shall be equitably adjusted.




                                      F - 1

Any DMNC  incentive/disincentive  payments will be determined  after October 31,
the end of the Summer  Operating  Period for each year and will be  reflected in
the first monthly invoice following the end of such Summer Operating Period.

II.  AVAILABILITY INCENTIVE/DISINCENTIVE

GENCO  will use its best  efforts to  maintain  its  generating  units such that
during the three month summer peak period (June through August) the availability
of its steam and internal  combustion  units meets or exceeds the  predetermined
level ("Target  Availability") as measured by the National Electric  Reliability
Council (NERC) - Generating  Availability Data System (GADS) Availability Factor
formula set forth as follows:

                                                AF= AH/PH

where:
         AH =  Available  Hours  are the sum of  in-service  hours  and  reserve
         shutdown  hours in the  period.  In-service  hours are defined as those
         hours where the unit is in service and  electrically  connected  to the
         system.  Reserve  shutdown  hours are those hours  whenever the unit is
         available to generate but is not  electrically  connected due to a lack
         of demand or the availability of lower cost power.

         PH = Period Hours are the total number of hours in the period.

Unit  availability is tracked and calculated by GENCO for submittal to NERC. All
data  collection,  reporting  and  calculations  are  defined  in the GADS  Data
Reporting Instructions.

The average  generation  availability for the GENCO system (for the June through
August period) shall be calculated annually ("Availability") as a weighted total
of each  units'  availability.  The  weighting  is based  on the Net  Dependable
Capacity (NDC), as submitted to NERC.

The  Availability  Target for each summer period (June through  August) shall be
97.5  percent of the simple  average of the annual  Availability  values for the
last five year period prior to the Closing Date.




                                      F - 2

<PAGE>



         5 Year  Average  Availability  = 96.5 percent (to be revised to reflect
         last five year period prior to the Closing Date)

         Target  Availability = 97.5 percent of 5 Year Average  Availability (to
         be revised to reflect last five year period prior to the Closing Date)

                         .975 * 96.5% = 94.1% (Target Availability)

As noted,  the above  target is based upon all of the  existing  GENCO steam and
internal combustion units in service. The Target Availability shall remain fixed
unless (a) LIPA exercises its option to Ramp Down GENCO's Generating Facilities,
or  (b)  any  of  GENCO's   Generating   Facilities  is   mothballed,   retired,
significantly  derated,  removed from service,  or incurs a long term outage for
unforeseen   reasons.   In  the  event  any  changes  are  required  the  Target
Availability will be adjusted appropriately.

For each year the Availability shall be compared with the Target Availability to
determine  the amount of  incentive  or  disincentive.  Should the  Availability
exceed the Target  Availability by 0.5 percent,  LIPA shall provide an incentive
payment to GENCO of $100,000.  Such incentive payment shall increase by $100,000
for each 0.1 percent  increase in the  Availability.  Should the Availability be
less  than  the  Target  Availability  by  0.5  percent,   GENCO  will  incur  a
disincentive of $100,000.  Such disincentive  shall increase by $100,00 for each
0.1 percent  decrease in the  Availability.  The maximum  incentive/disincentive
shall be $2 million annually.

In the event that LIPA does not approve  amounts for operating  and  maintenance
expenses and capital  expenditure,  that provide GENCO with the same opportunity
to  maintain  the  Availability  levels  as GENCO has at the  execution  of this
Agreement, such target levels shall be equitably adjusted.

Any Availability incentive/disincentive payments will be determined after August
30 for each year and will be reflected in the first  monthly  invoice  following
August 30.

IV. HEAT RATE INCENTIVE/DISINCENTIVE

GENCO will use its best efforts to maintain  the  efficiency  of its  generating
units in order to reduce the fuel  consumption for production of electric energy
for LIPA. An incentive or  disincentive  shall be determined  monthly based on a
measure of the overall  efficiency of GENCO's steam generating units,  including
steam  units  at the  Northport,  Barrett,  Glenwood,  Port  Jefferson,  and Far
Rockaway  power  stations,  in  comparison  with  a  predetermined  standard  as
described herein.

For  purposes  of this  incentive  plan,  LIPA  and  GENCO  have  established  a
functional  relationship  between monthly net generation (MWhN) and monthly fuel
burned,  expressed  in terms of millions  of British  thermal  units  ("MMBtu"),
considering  (i) the  relationship  between total net MWhN generated and average
efficiency  of the  generating  units;  and  (ii)  the  relative  efficiency  of
generating  units when burning natural gas or oil. This  relationship  (the "Btu
Curve") is expressed by the following equation:


     MMBtu = 10.7106* MWhN + 173,252
     Where:       MMBtu = Target Btu
                  MWhN = Steam Unit Net Generation

The Btu Curve represents the average amount of fuel required to generate a given
amount of monthly  electricity  (the "Target Btu") from GENCO's steam generating
units.

Each month the total net generation shall be used to establish the corresponding
Target  Btu based on the Btu Curve.  Actual  fuel used for  generation  shall be
expressed in Gas Equivalent MMBtu by multiplying the MMBtu of oil consumption by
1.04 (the "Gas  Conversion  Factor") to account for  differences  in the average
Unit Heat Rates when  burning  oil versus  natural  gas.  Deviations  in the Gas
Equivalent  MMBtu for the month in  comparison to the Target Btu shall be shared
as follows: (a) LIPA shall absorb the cost of fuel used for Gas Equivalent MMBtu
between  100% and 101% of the Target  Btu;  (b) LIPA shall  receive  the savings
resulting in the cost of fuel used for Gas Equivalent MMBtu between 99% and 100%
of the Target Btu; (c) LIPA and GENCO shall share equally in the cost or savings
resulting  from Gas  Equivalent  MMBtu in excess  of 101% or less  than 99%.  No
payments are contemplated under items (a) and (b) above.

There shall be no incentive or disincentive in any month when the net generation
from the GENCO steam Generating Facilities is less than 475,000 MWhN.

For purposes of computing  the  incentives  or  disincentives,  the cost of fuel
shall be stated in dollars  per Gas  Equivalent  MMBtu based on the cost of fuel
actually burned for generation in each month (i.e. that month's weighted average
fuel cost)  including  fuel cost  incentive or  disincentives  as defined in the
Energy  Management  Agreement,  and adjustment  for the Gas  Conversion  Factor,
applicable to the fuel oil burned.  The annual maximum incentive or disincentive
shall be $1 million.


                                      F - 5

The above BTU Curve equation is based upon all of the existing GENCO steam units
in service.  The BTU Curve shall  remain  fixed  unless (a) LIPA  exercises  its
options  to Ramp  Down  GENCO's  Generating  Facilities,  or (b) any of  GENCO's
Generating Facilities is mothballed,  retired,  significantly  derated,  removed
form  service,  or  incurs a long  term  outage  for  unforeseen  reasons.  If a
significant  change in the  operation of GENCO's  steam units occurs the Parties
shall mutually agree on modifications to the incentive/disincentive mechanism.

In the event that LIPA does not approve  amounts for operating  and  maintenance
expenses and capital  expenditure,  that provide GENCO with the same opportunity
to maintain  the Heat Rate target  levels as GENCO has at the  execution of this
Agreement, such target levels shall be equitably adjusted.

Any  incentive/disincentive  payments will be  determined  after the end of each
month and will be reflected in the first  monthly  invoice  following the end of
each month.

Manager  shall receive 33 percent of the revenue net of  incremental  costs from
Off-System  Sales of Electricity  from the System Power Supply and the Authority
shall  receive 67 percent of the  revenue  net of  incremental  costs from these
Off-System  Sales of Electricity  from the System Power Supply.  The incremental
costs for such  Off-System  Sales  will be based  upon the  incremental  cost of
energy  for  such  Electricity  sales  including  any  other  costs  or  charges
(including  applicable  taxes)  incurred to produce and deliver the  Electricity
and/or  Ancillary  Services for sale by Energy Manager.  The  incremental  costs
associated  with capacity sales shall include the cost of  replacement  capacity
incurred as a result of the sale, if any, and any other costs or charges related
to the sale, including startup, no-load operation,  transmission, and applicable
taxes.

         Amounts due to Energy  Manager  under this Article 4 shall be billed by
Energy Manager and shall be paid by the Authority in accordance with the billing
and payment provisions of Section 5.4.

         Notwithstanding  any of the above, the Energy Manager will only attempt
to sell  excess  Electricity  to the  extent  that,  in GENCO's  judgment,  such
Electricity  sales do not jeopardize any of GENCO's  tax-exempt  debt and to the
extent  that,  in  the  Authority's  judgment,  such  Electricity  sales  do not
jeopardize  the tax-exempt  status of any of the  Authority's  debt.  Each party
shall furnish the other an appropriately detailed description of the constraints
imposed  on  such  sales  prior  to the  Closing  Date  and  shall  update  such
description  from  time to time to  reflect  any  applicable  changes  in law or
regulation.

          Proceedings   against  the  Energy   Manager  by  any   contractor  or
          subcontractor  relating  to the  termination  of the Fuel  and  Energy
          Supply Services (or any Subcontracts);

               (8) take such other actions, and execute such other documents, as
          may be necessary to effectuate and confirm the foregoing  matters,  or
          as may be otherwise necessary or desirable to minimize the Authority's
          costs,  and take no action which will  increase any amount  payable to
          the Authority under this Agreement.

          7.5.2.  Authority  Payment of Certain  Transition Costs. The Authority
     shall reimburse the Energy Manager within 60 days of the date of the Energy
     Manager's  invoice for all mutually  agreeable costs incurred by the Energy
     Manager in satisfying the  requirements  of Section 7.5.1,  subject to Cost
     Substantiation.

         7.6. NO WAIVERS.  No action of the Authority or Energy Manager pursuant
to this Agreement (including, but not limited to, any investigation or payment),
and no failure to act,  shall  constitute  a waiver by either party of the other
party's  compliance with any term or provision of this  Agreement.  No course of
dealing or delay by the  Authority or Energy  Manager in  exercising  any right,
power or remedy  under  this  Agreement  shall  operate  as a waiver  thereof or
otherwise  prejudice  such party's  rights,  powers and  remedies.  No single or
partial  exercise of (or failure to exercise) any right,  power or remedy of the
Authority or Energy  Manager under this  Agreement  shall  preclude any other or
further exercise thereof or the exercise of any other right, power or remedy.

         7.7.  AUTHORITY  EMERGENCY  ASSUMPTION  OF FUEL AND SYSTEM POWER SUPPLY
MANAGEMENT   SERVICES.   Should  the  Energy  Manager,   due  to  Uncontrollable
Circumstances  or any  other  reason  whatsoever,  fail,  refuse or be unable to
provide any or all Fuel and System Power Supply Services contemplated hereby and
the  Authority or any  Governmental  Body finds that such  failure  endangers or
menaces the public health,  safety or welfare,  then, in any of those events and
to the extent of such failure,  the Authority shall have the right,  upon notice
to the  Energy  Manager,  during the period of such  emergency,  to perform  the
services  which the Energy  Manager  would  otherwise  be  obligated  to perform
hereunder.  The Energy Manager agrees that in such event it will fully cooperate
with the  Authority to effect such a temporary  assumption.  The Energy  Manager
agrees that,  in such event,  the  Authority  may take and use any or all of the
operating  assets  of the  Energy  Manager  necessary  for  the  above-mentioned
purposes  without  paying the Energy  Manager or any other person any additional
charges  or  compensation  whatsoever  for such  possession  and use;  provided,
however,  that if such  emergency is due to  Uncontrollable  Circumstances,  the
Authority  shall reimburse the Energy Manager for its  Cost-Substantiated  costs
incurred due to such a transfer of the operating assets. The parties acknowledge
that if the  Authority  assumes  the Fuel and System  Power  Supply  services in
accordance  with this Section 7.7, any  applicable  cure period  provided for in
this Agreement for the Energy Manager's  benefit shall be tolled until such time
as the Energy Manager  resumes  performance of its  obligations  hereunder.  The
Authority may use the Energy  Manager's  employees and the Energy  Manager shall
make its employees  available for such  purposes.  It is further agreed that the
Authority may at any time, at its discretion,  relinquish its performance of the
Fuel Services and System Power Supply Services  thereupon demand that the Energy
Manager  resume such services as provided in the Agreement.  It is  specifically
understood  and agreed that the  Authority's  exercise of its rights  under this
Section:  (1) does not constitute a taking of private property for which payment
must be made other than as specifically  provided for in this Section; (2) shall
not create any liability on the part of the Authority to the Energy Manager; and
(3) that the indemnity  provisions  of Article 11 hereof  covering the Authority
and the Energy Manager are meant to include


                                     - 29 -

circumstances  arising under this Section.  The Authority's right to perform the
services  anticipated  to be performed  by the Energy  Manager  hereunder  shall
terminate at the time when such services can, in the judgment of the  Authority,
be resumed by the Energy Manager.

         7.8. WAIVER OF CERTAIN DEFENSES.  The Energy Manager  acknowledges that
it is solely  responsible  for the  day-to-day  management  of Fuel Services and
System  Power  Supply  Services  and agrees  that,  unless  otherwise  permitted
pursuant to the  provisions of this  Agreement with respect to the occurrence of
Uncontrollable Circumstances, and without limiting such provisions, it shall not
assert (i) impossibility or impracticability of performance, (ii) the existence,
non-existence,  occurrence or non-occurrence of any foreseen or unforeseen fact,
event or contingency that may be a basic assumption of the Energy Manager,  (ii)
commercial  frustration of purposes or (iii) contract of adhesion,  as a defense
against any claim by the Authority against the Energy Manager.

                          ARTICLE 11 - INDEMNIFICATION


         11.1.  INDEMNIFICATION.  (A) Indemnification by the Energy Manager. The
Energy  Manager  agrees that,  to the extent  permitted by law, it will protect,
indemnify and hold harmless the  Authority and its  respective  representatives,
trustees,   officers,   employees  and  subcontractors  (as  applicable  in  the
circumstances),  (the "Authority Indemnified Parties") from and against (and pay
the  full  amount  of) any  Loss-and-Expense,  and  will  defend  the  Authority
Indemnified Parties in any suit,  including appeals,  for personal injury to, or
death of, any person,  or loss or damage to  property  arising out of any matter
for which Energy  Manager is  responsible  under Section 6.8. The Energy Manager
shall not,  however,  be  required  to  reimburse  or  indemnify  any  Authority
Indemnified   Party   for  any   Loss-and-Expense   to  the   extent   any  such
Loss-and-Expense  is  due  to  (a)  any  matter  for  which  the  Authority  has
responsibility  under Section 6.8 hereof,  (b) the  negligence or other wrongful
conduct of any Authority Indemnified Party, (c) any Uncontrollable Circumstance,
(d) any act or omission of any Authority Indemnified Party judicially determined
to be responsible for or contributing to the Loss-and-Expense, or (e) any matter
for which the risk has been specifically  allocated to the Authority  hereunder.
An Authority  Indemnified  Party shall promptly notify the Energy Manager of the
assertion  of any claim  against it for which it is entitled  to be  indemnified
hereunder,  shall give the Energy Manager the  opportunity to defend such claim,
and shall not settle the claim without the approval of the Energy  Manager.  The
Energy  Manager  shall be entitled to control the handling of any such claim and
to defend or settle any such claim, in its sole discretion,  with counsel of its
own choosing that is reasonably acceptable to the Authority Indemnified Parties;
provided,  however, that, in the case of any such settlement, the Energy Manager
shall  obtain  written  release of all  liability of the  Authority  Indemnified
Parties,  in  form  and  substance   reasonably   acceptable  to  the  Authority
Indemnified Parties.  Notwithstanding the foregoing,  each Authority Indemnified
Party  shall have the right to employ  its own  separate  counsel in  connection
with,  and to participate in (but,  except as provided  below,  not control) the
defense of, such claim, but the fees and expenses of such counsel incurred after
notice to the Energy Manager of its  assumption of the defense  thereof shall be
at the expense of such Authority Indemnified Party unless:

          (i)  the employment of counsel by such Authority Indemnified Party has
               been authorized by the Energy Manager;

          (ii) counsel to such Authority Indemnified Party shall have reasonably
               concluded that there may be a conflict on any  significant  issue
               between the Energy Manager and such Authority  Indemnified  Party
               in the conduct of the defense of such claim; or

          (iii)the  Energy  Manager  shall  not in fact  have  employed  counsel
               reasonably  acceptable  to the  Authority  Indemnified  Party  to
               assume  the  defense  of  such  claim  within  twenty  (20)  days
               following the receipt by the Energy

<PAGE>

               Manager  of the  notice  from  the  Authority  Indemnified  Party
               regarding the assertion of the applicable claim,

in each of which  cases the fees and  expenses  of  counsel  for such  Authority
Indemnified  Party  shall be at the  expense  of the Energy  Manager;  provided,
however,  that,  with  respect to clauses (ii) and (iii) of this  sentence,  the
Energy  Manager shall not be obligated to pay the fees and expenses of more than
one law firm, plus local counsel if necessary in each relevant jurisdiction, for
all such Authority Indemnified Parties with respect to any claims arising out of
the same  events or facts or the same  series of  events  or facts.  The  Energy
Manager shall not be entitled, without the consent of such Authority Indemnified
Party, to assume or control the defense of any claim as to which counsel to such
Authority Indemnified Party shall have reasonably made the conclusion that there
may be a conflict on any  significant  issue between the Energy Manager and such
Authority  Indemnified  Party in the conduct of the defense of such claim as set
forth in clause (ii) above,  provided that the foregoing  limitation shall apply
only with respect to those issues for which there may be such a conflict.  These
indemnification  provisions are for the protection of the Authority  Indemnified
Parties only and shall not  establish,  of  themselves,  any  liability to third
parties.  The provisions of this subsection 11.1(A) shall survive termination of
this Agreement.

         (B) Indemnification by the Authority.  The Authority agrees that to the
extent permitted by law, it will protect, indemnify and hold harmless the Energy
Manager  and  its  Affiliates   and  their   respective   officers,   directors,
Subcontractors  (as applicable in the  circumstances) and employees (the "Energy
Manager Indemnified  Parties") from and against (and pay the full amount of) all
Loss-and-Expense,  and will defend the Energy Manager Indemnified Parties in any
suit,  including  appeals,  for personal injury to, or death of, any person,  or
loss or damage to property  arising out of any matter for which the Authority is
responsible  under Section 6.8 hereof.  The  Authority  shall not,  however,  be
required to reimburse or indemnify any Energy Manager  Indemnified Party for any
Loss-and-Expense  to the  extent  any  such  Loss-and-Expense  is due to (a) any
matter for which the Energy Manager is responsible under Section 6.8 hereof, (b)
the  negligence  or other  wrongful  conduct of any Energy  Manager  Indemnified
Party,  (c) any  Uncontrollable  Circumstance,  (d) any act or  omission  of any
Energy Manager Indemnified Party judicially  determined to be responsible for or
contributing to the Loss-and-Expense, (e) any matter for which the risk has been
specifically  allocated  to the  Energy  Manager  hereunder.  A  Energy  Manager
Indemnified  Party shall  promptly  notify the Authority of the assertion of any
claim  against it for which it is entitled to be  indemnified  hereunder,  shall
give the Authority the  opportunity  to defend such claim,  and shall not settle
the claim without the approval of the Authority. The Authority shall be entitled
to  control  the  handling  of any such  claim and to defend or settle  any such
claim,  in its  sole  discretion,  with  counsel  of its  own  choosing  that is
reasonably  acceptable  to  the  Energy  Manager  Indemnified  Party;  provided,
however,  that, in the case of any such  settlement,  the Authority shall obtain
written  release of all liability of the Energy Manager  Indemnified  Party,  in
form and  substance  reasonably  acceptable  to the Energy  Manager  Indemnified
Party.  Notwithstanding the foregoing, each Manager Indemnified Party shall have
the right to employ its own separate


                                     - 35 -


<PAGE>

counsel in  connection  with,  and to  participate  in (but,  except as provided
below,  not  control)  the defense of, such claim,  but the fees and expenses of
such counsel  incurred  after notice to the  Authority of its  assumption of the
defense thereof shall be at the expense of such Energy Manager Indemnified Party
unless:

          (i)  the  employment  of counsel by such  Energy  Manager  Indemnified
               Party has been authorized by the Authority;

          (ii) counsel  to such  Energy  Manager  Indemnified  Party  shall have
               reasonably  concluded  that  there  may  be  a  conflict  on  any
               significant  issue between the Authority and such Energy  Manager
               Indemnified Party in the conduct of the defense of such claim; or

          (iii)the Authority shall not in fact have employed counsel  reasonably
               acceptable  to the  Authority  Indemnified  Party to  assume  the
               defense of such  claim  within  twenty  (20) days  following  the
               receipt by the  Authority  of the notice from the Energy  Manager
               Indemnified  Party  regarding  the  assertion  of the  applicable
               claim,

in each of which cases the fees and expenses of counsel for such Energy  Manager
Indemnified Party shall be at the expense of the Authority;  provided,  however,
that,  with respect to clauses (ii) and (iii) of this  sentence,  the  Authority
shall not be  obligated  to pay the fees and expenses of more than one law firm,
plus local  counsel if necessary  in each  relevant  jurisdiction,  for all such
Energy Manager Indemnified Parties with respect to any claims arising out of the
same events or facts or the same series of events or facts.  The Authority shall
not be entitled,  without the consent of such Energy Manager  Indemnified Party,
to assume or control the defense of any claim as to which counsel to such Energy
Manager  Indemnified  Party shall have reasonably made the conclusion that there
may be a conflict  on any  significant  issue  between  the  Authority  and such
Manager  Indemnified  Party in the  conduct of the  defense of such claim as set
forth in clause (ii) above,  provided that the foregoing  limitation shall apply
only with respect to those issues for which there may be such a conflict.  These
indemnification  provisions  are  for  the  protection  of  the  Energy  Manager
Indemnified Parties only and shall not establish,  of themselves,  any liability
to  third  parties.  The  provisions  of  this  Section  11.1(B)  shall  survive
termination of this Agreement.

the Authority (1) shall use reasonable efforts,  consistent with Applicable Law,
to provide notice to the Energy Manager of the request prior to any  disclosure,
and (2) shall use reasonable efforts, consistent with Applicable Law, to keep in

Loss-and-Expense  incurred  from  the  withholding  from  public  disclosure  of
information  designated  as  proprietary  by the  Energy  Manager  or  otherwise

     negotiation,  mediation, or arbitration procedures, proceed in any court to
     obtain  provisional  judicial  relief if, in such party's sole  discretion,

     information as ordered by the  Arbitrators and shall certify that they have

                                   APPENDIX A

                FUEL PURCHASE PERFORMANCE, INCENTIVE/DISINCENTIVE


The  Authority  and the  Energy  Manager  shall  share in  savings  realized  or
additional costs incurred when comparing the actual costs of monthly natural gas
and oil purchases for generation with the respective  natural gas and oil target
indices  described  herein.  The amount of  incentive  or  disincentive  will be
determined monthly on a transaction by transaction basis. The maximum net annual
incentive or  disincentive  shall be limited to the provisions of Section 3.3 of
the  Energy  Management  Agreement.  All  units of fuel  shall be  converted  to
millions  of  British  thermal  units - dry  ("MMBtu")  for  purposes  of  these
calculations.


1.       NATURAL GAS PURCHASES


         1.1      Benchmark Gas Index Price

An index  shall be  computed  and  expressed  in dollars  per MMBtu (the  "Index
Price")  for each  monthly  purchase  arrangement  for the three  categories  as
described  below.  The three  categories  are  intended to  incorporate  all gas
purchases  for  generation  without  exception.  There shall be no allowance for
losses and  unaccounted-for  gas between the City Gate and the billing meters at
each  generating  station.  For this purpose,  the term "Bid Week" is defined to
mean for the week in the prior month during which gas prices are established for
the current month.


a.   The Index  Price for gas  purchases  made after Bid Week for a duration  of
     less than one month ("Swing Gas Purchases")  shall be based on the delivery
     area and pipeline  specific Daily Midpoint index published by Gas Daily for
     the first business day of gas flow under the transaction  (e.g.,  "Others -
     Transco, Zone 6" index).


b.   The Index Price for gas purchases  made prior to or during  Bid-Week with a
     duration of one month or less  ("Monthly Gas  Purchases")  shall be derived
     separately for each pipeline source as the equally  weighted average of (i)
     the Gas Daily  Price  Guide  Monthly  Contract  Index or City  Gate  Prices
     Average of the high and low Bid Week  posting for a specific  pipeline  and
     region,  as  appropriate;  and (ii) the price for a specific  pipeline  and
     region,  as  appropriate,  published in Inside FERC Gas Market Report as of
     the first day of the month.


<PAGE>

c.   The  Index  Price  for gas  purchases  with a term  greater  than one month
     ("Long-Term Gas Purchases")  shall be determined for each such contract for
     Long-Term  Gas Purchases as the index for Swing Gas Purchase or Monthly Gas
     Purchases,  as described  above plus an  adjustment  to reflect the premium
     paid for  long-term  supply (the  "Long-Term  Adjustment").  The  Long-Term
     Adjustment  shall  be  computed  annually  as the  difference  between  the
     weighted  average  cost per MMBtu of Long-Term  Purchases  and the weighted
     average cost of all other  supplies.  If the historical  data for Long-Term
     Gas Purchases for electric generation is inadequate,  average costs for all
     other   long-term   purchase   contracts  by  the  Energy  Manager  may  be
     substituted.  Appropriate  transportation costs will be added to each index
     so determined.


         1.2      Calculation of Incentive/Disincentive for Gas Purchases


A  benchmark  price  shall  be  computed  for  each  purchase  (the  "Gas  Index
Benchmark")  equal to 102% of the Index Price  determined in Section 1.1 of this
Appendix.  The "Actual Gas Cost" shall be computed for each purchase transaction
as the average cost per MMBtu of all costs  associated  with such  transactions,
including  commodity and demand  charges,  and excluding any penalties and fines
incurred  by Energy  Manager.  Should  the  Actual Gas Cost be less than the Gas
Index  Benchmark the  Authority  and the Energy  Manager shall share the savings
equally. Should the Actual Gas Cost exceed the Gas Index Benchmark the Authority
and the Energy Manager shall share such excess cost equally.  For each month the
amount of incentive or disincentive  associated  with each purchase  transaction
shall be computed as the product of the resulting incentive or disincentive cost
per unit and the actual volume of gas purchased.


2.       OIL PURCHASES


The target  price for oil  purchases  expressed  as dollars  per MMBtu (the "Oil
Index Benchmark") shall be computed each month for each type of oil purchase for
each purchase transaction.


         2.1      Residual Oil Purchases


The Oil Index  Benchmark  for  residual oil  purchases  shall be computed as the
weighted  average of applicable  residual oil spot postings as described  below,
and shall be determined  separately for (nominal)  1.0% sulfur,  0.7% sulfur and
0.3% sulfur No. 6 residual fuel oil ("Residual Oil Purchase") depending on which
type of oil is  delivered  for each  delivery  based  on the date on which  each
delivery  commences (the  "Commencement of Discharge Date). All index prices for
each  delivery  shall be computed as the  average of the spot  postings  for the
Commencement of


                                        2


<PAGE>

Discharge Date, the two days prior to such date, and the two days following such
date (the "Residual Oil Index Period").


a.   Forty  percent of the  International  Heavy Fuel Oil Prices,  Delivered New
     York Spot,  Cargoes  1.0% sulphur LP, or 0.7% sulphur LP, or 0.3% HP, price
     as posted in Bloomberg Petroflash!  at 5:00 PM Eastern Time for each day of
     the Residual Oil Index Period.


b.   Forty  percent of the average of Cargoes,  DEL NYH 1.0% sulphur LP. or 0.7%
     sulphur  LP,  or 0.3%  sulphur  HP  low/high  prices  as posted in Argus US
     Products  in  Houston,  at 5:00 PM  Central  Time,  for  each of day of the
     Residual Oil Index Period.


c.   Twenty percent of the average New York Cargo,  No. 6 1% sulphur LP, or 0.7%
     sulphur LP. or 0.3% sulphur HP low/high prices as posted in Platt's Oilgram
     U.S.  Marketscan  price  report at 5:00 PM Eastern Time for each day of the
     Residual Oil Index Period.


In  computing  the Oil Index  Benchmark  the above  indices will be increased to
include the actual  transportation  charge to each GENCO Generating  Facility as
appropriate.


         2.2     No. 2 Oil - Barge Delivery


For No. 2 oil purchases,  the Oil Index  Benchmark shall be equal to the average
of the three spot  postings,  as defined  below,  for each of the following days
(the "Daily Averages"):  the Commencement of Discharge Date; the day before such
date,  and the day after such date (the "No.  2 Oil Barge  Index  Period").  The
following  postings for spot barge No. 2 oil ("Spot  Postings")  will be used to
determine the daily average for each of the referenced days:


a.   The low "New York Barge No. 2" price as published  in Platt's  Oilgram U.S.
     Marketscan  price  report at 5:00 PM Eastern Time for each day of the No. 2
     Oil Index Period.


b.   The  "New  York  Heating/Gas  Oil:  0.2%  Sulphur"  price as  published  in
     Bloomberg Petroflash! At 5:00 PM Eastern Time for each day of the No. 2 Oil
     Index Period.


                                        3


<PAGE>

C.   The low "DEL NYH No. 2" price as posted in Argus US Products in Houston, at
     5:00 PM Central Time, for each of day of the No. 2 Oil Index Period.


In  computing  the Oil Index  Benchmark  the above  indices will be increased to
include appropriate handling, terminalling,  storage, and transportation charges
to each GENCO Generating Facility.


         2.3     No. 2 Oil  - Truck Delivery


For No. 2 oil  purchases the target index shall be equal to the average of "low"
or "average"  price, as appropriate,  for each supplier of fuel oil, for Newark,
NJ **OPIS/Tape Gross Distillate Prices*" Hi Sul No. 2" as published in Oil Price
Information Service at the close of business Eastern Time on the Commencement of
Discharge  Date, the day before such date and the date after such date (the "No.
2 Oil Truck Index Period").


The above  target  index  will be  modified  to  include  appropriate  handling,
terminalling,  storage,  and  transportation  charges to each  GENCO  Generating
Facility.


         2.4      Kerosene - Barge Delivery


For  kerosene  purchases,  the target index shall be equal to the average of the
New York Barge LS Jet Low Price as published in Platt's Oilgram U.S.  Marketgram
price report at 5:00 PM Eastern Time effective for the Commencement of Discharge
Date, the day before such date, and the day after such date (the "Kerosene Index
Period").


In  computing  the Oil Index  Benchmark  the above  indices  will be modified to
include appropriate handling, terminalling,  storage, and transportation charges
to each GENCO Generating Facility.


         2.5      Calculation of Incentive/Disincentive for Oil Purchases


The "Actual Oil Cost" shall be computed  for each  purchase  transaction  as the
average cost per MMBtu of all costs associated with such transaction. Should the
Actual Oil Cost be less than the corresponding Oil Index Benchmark, LIPA and the
Energy  Manager  shall  share the  savings  equally.  Should the Actual Oil Cost
exceed the Oil Index Benchmark, the Authority and the Energy Manager shall share
such excess cost equally. For each month the amount of incentive


                                        4


<PAGE>

or disincentive  associated with each purchase  transaction shall be computed as
the product of the  resulting  incentive or  disincentive  cost per unit and the
actual volume of oil purchased.


The net amount of incentive or  disincentive  payment will not exceed $5 million
on an annual basis.


3.     SUBSTITUTION OF INDICES


In the  event  that any of the  posted  indices  referenced  herein  cease to be
published,  their  basis  of  determination  materially  changes  or  new,  more
appropriate  indices  are  published,  the  parties  may agree to  substitute  a
mutually agreeable index.

                                   APPENDIX B
             SYSTEM POWER SUPPLY PERFORMANCE INCENTIVE/DISINCENTIVE


Recognizing that incentives for favorable fuel prices, and GENCO generating unit
efficiencies are provided as part of this or other agreements,  the power supply
cost  incentive/disincentive  shall be based on the  actual  cost of  off-system
power purchases,  excluding purchases under long-term contracts in effect on the
Closing Date, in comparison to an indexed cost as described herein.


Each month, an indexed cost of purchased power shall be computed for on-peak and
off-peak purchases for each week during the month in the amount equal to the sum
of (i) the  product  of the  quantities  for each week in the  month of  on-peak
purchases  and the  corresponding  Prices of Spot  Electricity  - East New York,
Weekly Index (on-peak)  published weekly in Power Markets Week; (ii) the product
of the  quantities  for each week in the  month of  off-peak  purchases  and the
corresponding Prices of Spot Electricity - East New York, midpoint of the Weekly
Range (off-peak),  published weekly in Power Markets Week; and (iii) the product
of total on-peak and off-peak purchases and a Basis Differential  computed for a
12-month period prior to the Commencement Date (the "Target Purchase Cost"). The
Basis  Differential  shall be computed as the  difference  between the  weighted
average per cost MWh of purchase indexed as described above, excluding the Basis
Differential  component,  and the actual cost of purchases  per MWh. The parties
agree that in the event  that any index  ceases to be  published,  or there is a
substantial  change in the  manner in which  the index is  established,  another
mutually  agreeable  index shall be substituted,  and/or the  Basis/Differential
shall be recomputed, as appropriate.


For each month,  if the Actual  Purchase  Cost is less than the Target  Purchase
Cost,  the  Authority  shall pay Energy  Manager 33% of the savings.  Should the
Actual  Purchase Cost exceed 101% of the Target  Purchase  Cost,  Energy Manager
shall incur a penalty equal to 33% of such excess cost. In any other event,  the
Authority  shall  reimburse  Energy Manager for the Actual Purchase Cost with no
adjustment  for  incentive  or penalty  amounts.  The net amount of incentive or
penalty will not exceed $2 million on an annual basis.

          and generally deal with potential M/WBE  subcontractors  in a fair and
          responsive manner, allowing them the opportunity to participate in the
          Contract Scope of Work.

          (2) The Energy Manager will designate, and make known to the Authority
          an M/WBE Officer who will have the responsibility for and authority to
          effectively administer the M/WBE Program.

          (3) The Energy  Manager  shall submit its  Preliminary  Subcontracting
          Plan on a preliminary  subcontracting  plan form, which shall identify
          the Certified  Businesses  it will utilize to meet its M/WBE  Contract
          Goals.  Approval of any such firm is solely  within the  discretion of
          the Authority. The Energy Manager will also designate an M/WBE Officer
          who will have the  responsibility  for, and authority to,  effectively
          administer these procedures.  If the Energy Manager believes it may be
          unable to meet the Goals,  the reasons  shall be  submitted in writing
          with the form.


                                        6


<PAGE>

          (4) The  Energy  Manager  may  inspect  the  current  New  York  State
          Certification  Directory  of  Minority  and  Women  Owned  Businesses,
          prepared for use by state  agencies and  contractors in complying with
          Executive Law Article 15-A, (the Directory) at the Authority's office.
          In addition,  printed or  electronic  copies of the  Directory  may be
          purchased   from  the  Office  of  Minority   and   Women's   Business
          Development.

          (5) Firms  certified as both MBE and WBE may count  toward  either the
          MBE or WBE Goal on a single  contract,  but not  both,  regardless  of
          whether either Goal is thus  exceeded.  The Energy Manager must choose
          the Goal to which  the  participation  value is to be  applied  in the
          preliminary Subcontracting Plan.

          (6) Within 10 days  following  the adoption of the initial  Annual T&D
          Budget and in any event no later than 60 days prior to the anticipated
          Closing Date, the Energy  Manager shall submit a complete  Utilization
          Plan,  which  shall  include  identification  of the M/WBEs  which the
          Energy Manager intends to use; the dollar amount of business with each
          such  M/WBE;  the  Contract  Scope of Work  which the  Energy  Manager
          intends to have performed by such M/WBEs; and the commencement and end
          dates of such  performance.  The  Authority  will review the plan and,
          within 20 days of its receipt,  issue a written acceptance of the plan
          or comments on deficiencies in the plan.

          (7) The  Authority  shall  consider a partial or total  waiver of Goal
          requirements  only  upon the  submission  of a written  request  for a
          waiver following the Energy Manager's  unsuccessful good faith efforts
          at compliance. Such waiver request may be made simultaneously with the
          submission of the Utilization Plan.

          (8) The Energy  Manager shall include in each  Subcontract,  in such a
          manner that the  provisions  will be binding upon each  subcontractor,
          all of the provisions herein including those requiring  subcontractors
          to make a good faith effort to solicit participation by M/WBEs.

          (9) The  Energy  Manager  shall  keep  records,  canceled  checks  and
          documents  for at least  one (1)  year  following  completion  of this
          Agreement.  These records,  and canceled  checks,  documents or copies
          thereof  will be made  available  at  reasonable  times  upon  written
          request by the Authority or any other authorized governmental entity.

          (10) The  Energy  Manager  shall  submit  monthly  compliance  reports
          regarding its M/WBE  utilization  activity on a Compliance Report Form

          of each month, beginning 30 days after the Closing Date.

          (11) The Authority will conduct  compliance  reviews for determination
          of the Energy Manager's  performance relative to meeting the specified
          M/WBE  Goal  which may  include  review and  inspection  of  documents
          pertaining to the Energy Manager's efforts


                                        7


<PAGE>

          towards  meeting the Goals and on-site  interviews  with  personnel of
          Energy Manager and its  subcontractors.  The Energy Manager will fully
          cooperate to assist the Authority in this endeavor.

          (12) The Energy Manager shall not use the requirements of this section
          to discriminate against any qualified company or group of companies.

          (d) CONDITIONS FOR SATISFYING M/WBE GOALS. M/WBE participation will be
          counted toward the total Contract M/WBE Goals subject to the following
          conditions:

         (1) If the Energy  Manager  is unable to meet the Goals with  Certified
         Businesses by making all of the good faith efforts defined herein,  the
         Energy Manager shall actively solicit uncertified M/WBEs to satisfy the
         Goals.  Uncertified firms will be required to submit an application for
         certification   (to  the  Office  of  Minority  and  Women's   Business
         Development)  and will be counted as contributing  towards the contract
         Goals only after they have been certified.

          (2) The  Energy  Manager  must keep  records  of  efforts  to  utilize
          certified M/WBE's including

               (i) The firm's name, address and telephone number.

               (ii) A description of the information provided to the M/WBE.

               (iii) A written  explanation  of why an agreement  with the M/WBE
               was not obtained.

          (3) Price alone will not be an acceptable  basis for  rejecting  M/WBE
          bids if any of the bids are reasonable.

          (4)  Geographical  limitation in the M/WBE search is not an acceptable
          reason for not  meeting  the M/WBE goal when  traditionally  non-local
          firms have been generally utilized.

          (5) the  Authority  reserves  the right to reject any firm as counting
          toward meeting the Energy  Manager's  M/WBE goal if, in the opinion of
          the  Authority,  the facts as to that firm's  business  and  technical
          organization and practices justify the rejection.

          (e)  ENERGY  MANAGER'S   GOOD-FAITH  EFFORTS.  To  satisfy  the  M/WBE
          participation  requirements,  the  Energy  Manager  agrees to make the
          following good-faith efforts in a timely manner:

          (1)  Submission  of  a  completed,   acceptable  Utilization  Plan  as
          described herein.


                                        8


<PAGE>

          (2) Advertising in appropriate general circulation, trade and minority
          and women-oriented publications.

          (3)  Written  solicitations  made  in a  timely  manner  of  certified
          minority  and  women-  owned  business   enterprises   listed  in  the
          Directory.

          (4)  Attendance at meetings,  if any,  scheduled by the Authority with
          certified M/WBEs capable of performing the Contract Scope of Work.

          (5) Written  notification to M/WBE trade  associations  located within
          the region where the Contract Scope of Work will be performed.

          (6)   Structuring   the  Contract   Scope  of  Work  for  purposes  of
          subcontracting with certified M/WBEs.

          (7) Where  certified  M/WBEs have  expressed an interest to the Energy
          Manager in performing work that the Energy Manager  normally  performs
          with its own sources and the Contract Scope of Work has not been fully
          performed,  the Energy Manager shall consider subcontracting such work
          or portions of it to meet the M/WBE Goals.

1.9.  COMMENCEMENT OF ACTIONS ON STATE PUBLIC WORKS  CONTRACTS.  The time within
which an action on this  Agreement  against the Energy Manager must be commenced
shall be computed from the date of completion of the physical  work.  The Energy
Manager may notify the  Authority in writing,  that such  physical work has been
completed  by  specifying a  completion  date,  which date shall be no more than
thirty days  previous to the date of such notice,  in which case the  completion
date set forth in such notice  shall be deemed to be the date of  completion  of
the physical  work unless the  Authority,  within thirty days of receipt of such
notice, notifies the Energy Manager in writing of its disagreement. In the event
that the  Energy  Manager  fails to send the notice  provided  for herein or the
Authority disagrees in the manner provided herein, the date of completion of the
physical work shall be determined in any other manner provided by law.

                  (a) Upon receipt of the Notice, Buyer shall be legally
         bound to purchase,  and Seller shall be legally  bound to sell,

Seller shall  deliver to Buyer  documents  sufficient to cause the entire right,
title and  interest in and to all  outstanding  Interests to be  transferred  of
record to Buyer and in consideration thereof Buyer shall pay to Seller an amount
in cash equal to the Purchase Price.  All such payments and deliveries  shall be
deemed to occur  simultaneously  as a single  transaction and no such payment or
delivery shall be effective  unless all such payments and  deliveries  have been
made.

            Section 2.9 Provision of Corporate Records.  Seller shall arrange as
soon as practicable  following the Closing Date for transportation,  at Seller's
cost, to Buyer of the records in Seller's  possession  relating to the assets of

transferred  hereunder  shall be made on an "as-is"  basis  without  recourse to

implied,  except in each case as expressly set forth in this  Agreement.  Seller
makes  no  representation  and  takes  no  responsibility  with  respect  to the

                               THE PURCHASE PRICE

            Section 3.1 Purchase  Price.  The purchase  price for the  Interests
("Purchase  Price")  shall be the Fair  Market  Value  of the  Interests,  to be
determined  as of the Exercise  Date by two  independent  nationally  recognized
investment  banking firms  experienced in the valuation of comparable  property,
one of which shall be appointed by each of Buyer and Seller  (collectively,  the
"Investment  Bankers")  to  negotiate  and agree  upon  Fair  Market  Value.  In
determining the Fair Market Value, the Investment  Bankers shall consider all of
the terms of the Power Supply Agreement for the term of such agreement.

            Section 3.2 Arbitration.  If the Investment  Bankers are not able to
agree on the Fair Market Value or such appropriate interest rate, then Buyer and
Seller  will  select a  mutually  agreeable  independent  nationally  recognized
investment banking firm experienced in the valuation of comparable properties to
provide  its  determination  of the Fair  Market  Value,  which  will be used to
determine the Purchase Price and will be conclusive and binding on the parties.

            Section 3.3 Disclosure of Third Party Offers.  If at any time within
six months of the Exercise Date and prior to the Closing Date Buyer has received
any binding or serious  offers  from any third party to purchase  some or all of
the assets of Genco, Buyer shall disclose the terms and existence of such offers
to Seller and to the Investment Bankers. If Buyer agrees to any such third-party
offers and consummates such transaction  within 3 months after the Closing Date,
Seller will pay to Buyer 50% of Buyer's reasonable  incremental  financing costs
(excluding  interest or other costs of carry), if any, and including legal fees,
underwriter's compensation and other costs of issuance,  specifically related to
such financing, if any, up to $2 million.

                         REPRESENTATIONS AND WARRANTIES

            Section  4.1  Representations  and  Warranties  of Seller and Genco.
Except for the  representation  and warranty  contained in Section  4.1(a),  the
following representations and warranties are furnished solely for the purpose of
facilitating  the  determination of Fair Market Value and shall not preclude the
Investment  Bankers from  pursuing such due diligence as they require to perform
their obligations hereunder. Seller and Genco, jointly and severally,  represent
and warrant to the Buyer at the Closing and on the Closing Date that,  except as
disclosed  to Buyer in writing on the date  hereof and as updated in writing not
later than the date the Audited  Balance Sheet is delivered and further  updated
in  writing  by Seller  prior to the  determination  of Fair  Market  Value (the
"Schedule"):

                  (a)  Ownership  of  Interests.  On the  Closing  Date,
         Seller will own and hold, beneficially, the entire right, title
         and interest in and to all of the then existing  Interests free
         and clear of all Liens.  As of the Closing Date,  there will be
         no outstanding subscriptions, options, calls, contracts, voting
         trusts,   proxies   or   other   commitments,   understandings,
         restrictions,  arrangements,  rights or warrants, including any
         right of conversion or exchange under any outstanding security,
         instrument  or other  agreement,  obligating  Genco  to  issue,
         deliver  or sell,  or cause to be  issued,  delivered  or sold,
         additional  Interests,  or obligating Genco to grant, extend or
         enter into any such agreement or commitment.

                  (b) Execution and Enforceability. Seller has and Genco
         will have as of the Closing all  requisite  power and authority
         to execute and deliver  this  Agreement  and to perform each of
         their obligations hereunder.  Seller has and Genco will have as
         of the Closing  duly  authorized  the  execution,  delivery and
         performance  of this  Agreement.  This  Agreement is the legal,
         valid and binding  obligation  of Seller and will be the legal,
         valid and binding  obligation  of Genco as of the Closing,  and
         (assuming  that  this  Agreement  has  been  duly   authorized,
         executed and delivered by Buyer) is enforceable  against Seller
         and Genco in accordance with its terms.

                  (c)  Organization  and  Qualification of Genco. On the
         Closing  Date,  Genco  is  a  limited  liability  company  duly
         organized, validly existing and in good standing under the laws
         of the State of New York and will have all requisite  power and

         and lease its properties and assets. On the Closing Date, Genco
         will be qualified to do business


                                      - 8 -

         and  in  good  standing  in  each  jurisdiction  in  which  the
         ownership of its  property or the conduct of its business  then
         requires such qualification.

                  (d) No Violations or Conflicts.  Neither the execution
         and  delivery  of this  Agreement  by  Seller  or Genco nor the
         consummation of the transactions contemplated by this Agreement
         (i)  results  in a  violation  or breach of, or  constitutes  a
         default  or an  event  of  default  under,  any  bond or  other
         material  Contract,  Permit,  instrument or other obligation to
         which  Seller or Genco is a party,  or (ii)  violates any Laws,
         writ, judgment, injunction or court decree.

         Person is required to be made or obtained by Genco or Seller in
         connection with the execution, delivery and performance of this
         Agreement by Genco or Seller.  On the Closing Date, all notices
         or other actions required to be made or taken, if any, pursuant
         to any applicable  Laws to permit the closing of this Agreement
         will have been made and taken.

                  (f) Compliance with Laws; Permits.  The operations and
         activities of Genco are in compliance with all Laws and neither
         Seller or Genco has received any notice to the contrary.  Genco
         has  all  material  Permits  required  for  it to  conduct  the
         Business  and no  material  violations  have been  recorded  in
         respect of any Permits and no  proceeding is pending or, to the
         knowledge of Seller,  threatened with respect to the limitation
         or revocation of any Permit.

                  (g) Audited  Balance Sheet.  The Audited Balance Sheet
         will, as of and for the periods ended on the  applicable  date,
         fairly  present,  in  all  material  respects,   the  financial
         position and results of operations of Genco as of the dates and
         for the  periods  presented  therein in  accordance  with GAAP,
         applied on a  consistent  basis  during the periods  concerned,
         except as otherwise noted therein.

                  (h)      Records.  The books of account and records of
         Genco fairly reflect, in all material respects, all of the
         properties, assets, liabilities and transactions of Genco.

                  (i)      Assets.  On the Closing Date, Genco will have 
         good and marketable title (except to the extent that such assets


                                      - 9 -

         Genco to  deliver to Buyer  copies of all deeds,  endorsements,
         assignments  and  other  good  and  sufficient  instruments  to
         evidence  Genco's  right,  title and interest in and to any and
         all of the  Generating  Facilities,  as  Buyer  may  reasonably

         properties  that are owned by Genco,  and such  properties  are
         free  and  clear  of  all  debts,   Taxes,   claims,   options,

                             that alleges that Genco is not in such

                             formerly leased or managed, in whole or in part.

                  (iv)       Releases.  Genco has no knowledge of any
                             material Releases (as defined in Section
                             4.1(j)(vii)(D)) of any Hazardous Material (as
                             defined in Section 4.1(j)(vii)(C)), that would
                             be reasonably likely to form the basis of any
                             material Environmental Claim against Genco, or
                             against any person or entity whose liability for

                             may have retained or assumed either
                             contractually or by operation of law.

                  (v)        Predecessors.  Seller  and  Genco  have  no
                             knowledge,  with respect to any predecessor
                             of Genco's,  of any material  Environmental
                             Claim  pending  or  threatened,  or of  any
                             Release of Hazardous  Materials  that would
                             be  reasonably  likely to form the basis of
                             any material Environmental Claim.

                  (vi)       Disclosure.  Seller and Genco have disclosed to
                             Buyer all material facts which they reasonably
                             believe form the basis of a material
                             Environmental Claim arising from (A) the cost of
                             Genco pollution control equipment currently
                             required or known to be required in the future

                             be required in the future with respect to the
                             Generating Facilities; or (C) any other
                             environmental matter affecting Genco with
                             respect to the Generating Facilities.

         all  commercially  reasonable  efforts to obtain  all  required
         consents  for the exercise of the Right.  Genco shall  promptly
         notify  Buyer of any failure or  prospective  failure to obtain
         any such  consents  and, if requested by Buyer,  shall  provide

         result in a material  breach of any provision of this Agreement

         this Agreement, being untrue on and as of the Closing Date.

                  (l) Tax-Exempt Status. Genco shall not take any action
         that  would  likely  jeopardize  the  qualification  of Genco's
         outstanding  revenue  bonds  which  qualify on the date  hereof
         under Section 142(a) of the Code as "exempt  facility bonds" or
         as  tax-exempt  industrial   development  bonds  under  Section
         103(b)(4)  of the Internal  Revenue  Code of 1954,  as amended,
         prior to the Tax Reform Act of 1986.

         commercially   reasonable   efforts  to  obtain  all   required
         third-party  consents.  Buyer shall promptly  notify Seller and
         Genco of any failure or prospective  failure to obtain any such
         consents  and, if requested by Seller or Genco,  shall  provide
         copies of all such consents obtained to Seller and Genco.

                  (b) No Breach, Etc. Buyer shall not willfully take any
         action  that  would or is  reasonably  likely  to  result  in a

         being untrue on and as of the Closing Date.

                  (c)  Buyer  Actions.   Buyer  shall  take  only  those
         actions,  from the date hereof until the Closing Date, that are
         required or  contemplated  by this  Agreement to be so taken by
         Buyer, including,  without limitation, the declaration,  filing
         or registration with, or notice to or authorization, consent or
         approval of, any Governmental Authority.

            Section 5.3 Additional Agreements.

                  (a) Notification of Certain Matters. Commencing on the
         third anniversary  hereof,  each party hereto shall give prompt
         notice to the other  parties  hereto of (i) the  occurrence  or
         failure  to occur of any  event,  which  occurrence  or failure
         would be  reasonably  likely  to cause  any  representation  or
         warranty  of  such  party  contained  herein  to be  untrue  or
         inaccurate  in any  material  respect  at any  time,  (ii)  any
         material  failure of such party to comply  with or satisfy  any
         covenant,  condition  or  agreement  to  be  complied  with  or
         satisfied by it hereunder,  and (iii) any newly discovered fact
         or  circumstance  that might  reasonably  be expected to have a
         material  effect  on  the  accuracy  of any  representation  or
         warranty of such party contained herein.

                  (b) No Layoffs or Salary Cuts.  For a period of two
         years following the Closing Date, Buyer shall not cause or
         permit to occur any layoffs or salary cuts to any non-union
         Genco personnel.

                  (c)  Management  Contract.  If  Buyer  elects  in  the
         Exercise  Notice to retain  Seller or an Affiliate of Seller to
         operate the Generating  Facilities,  the parties will negotiate
         in good faith the terms and conditions of a mutually acceptable
         agreement therefor.

                  (d)  Easements.  Prior to the Closing Date,  Genco may
         grant  Seller an  irrevocable  and  perpetual  easement for the
         installation,  maintenance  and  access of and to any assets of
         Seller or its  affiliates or  subsidiaries  located on or under
         such  property,  provided  if  Seller's  use of  such  easement
         materially interferes with either the physical operation of any
         generating facilities or with Buyer's environmental compliance,
         Seller shall  compensate  Buyer for the adverse impact on Buyer
         of such interference.

resolution of such disputes.

      (b) The parties  agree to use their best  efforts to settle  promptly  any
disputes  or  claims  arising  out of or  relating  to  this  Agreement  through
negotiation conducted in good faith between executives having authority to reach
such a  settlement.  If either party hereto shall so request,  the parties shall
mutually agree on the selection of a mediator who shall mediate the negotiations
which shall be non-binding.

         All  negotiations  and mediation  discussions  pursuant to this
paragraph  are  confidential  and shall be  treated  as  compromise  and
settlement negotiations for purposes of Federal Rule of Evidence 408 and
applicable state rules of evidence.

requested,  shall be settled by binding arbitration before three independent and

<PAGE>

Agreement, in which case the provisions of this Agreement shall be followed, and
except that the  arbitrations  under this Agreement shall not be administered by
the American Arbitration  Association.  The Arbitrators shall be (i) independent
of the parties and disinterested in the outcome of the dispute,  (ii) attorneys,
accountants,  investment bankers,  commercial bankers or engineers familiar with
contracts  governing  the  operation  of  electric  utility  assets,  and  (iii)
qualified  in the  subject  area of the issue in  dispute.  For  purposes of the
preceding sentence,  residents of Long Island shall not be considered interested
merely by  virtue of their  residence.  The  Arbitrators  shall be chosen by the
parties,  with each party choosing one arbitrator and those arbitrators choosing
the third  arbitrator.  Judgment on the award rendered by the Arbitrators may be
entered in any court in the State of New York having  jurisdiction  thereof.  If
either  party  refuses  to  participate  in good  faith in the  negotiations  or
mediation  proceedings described in paragraph (b) hereof, the other may initiate
arbitration at any time after such refusal without waiting for the expiration of
the 60 day  period.  Except  as  provided  in  Paragraph  D hereof  relating  to
provisional  remedies,  the Arbitrators  shall decide all aspects of any dispute
brought to them including  attorney  disqualification  and the timeliness of the
making of any claim.

      (d) Either party may, without prejudice to any negotiation,  mediation, or
arbitration procedures, proceed in any court to seek provisional judicial relief
if, in such party's sole discretion,  such action is necessary to avoid imminent
irreparable harm, to provide uninterrupted  electrical and other services, or to
preserve  the  status quo  pending  the  conclusion  of the  dispute  procedures
specified in this Section.

      (e) The Arbitrators  shall have no authority to award punitive  damages or
any other damages aside from the  prevailing  party's  actual and  consequential
damages,  plus  interest  thereon at the Best  Interest  Rate (as defined in the
Management  Services  Agreement),  accrued  from  the  date  such  damages  were
incurred.  The  Arbitrators  shall not have the  authority  to make any  ruling,
finding,  or award  that does not  conform to the terms and  conditions  of this
Agreement.

      (f) The Arbitrators may award reasonable  attorneys' fees and costs of the
arbitration.

      (g) Any claim under this  Agreement  shall be time- barred,  regardless of
any statute of  limitations  periods  provided by state or federal  law,  unless
negotiation or mediation with respect  thereto is commenced with respect to such
claim within twelve months after the basis for such claim has been discovered.

      (h) The  Arbitrators  shall  have the  discretion  to order a  pre-hearing
exchange of information by the parties,


                                     - 23 -


<PAGE>

including,  without  limitation,  the  production  of requested  documents,  the
exchange of summaries of testimony of proposed witnesses, and the examination by
deposition of parties.  Each of the parties agrees to produce all such requested
documents  and to  deliver  to the  other a  certificate,  executed  by a senior
executive of such party, stating that all such documents have been so produced.

      (i) The site of any Arbitration  brought  pursuant to this Agreement shall
be Mineola or Hauppauge, New York.

      (j) The  Arbitrator's  award  shall be in writing  and shall set forth the
factual and legal bases for the award.

                               GUARANTY AGREEMENT


         THIS  GUARANTY  AGREEMENT  is made and dated  _______,  199__,  from BL
HOLDING CORP., a corporation  organized and existing under the laws of the State
of New York (together with any permitted  successors and assigns hereunder,  the
"Guarantor"), to Long Island Power Authority (together with its subsidiaries and
other   permitted   assignees  of  the  Agreements  (as  defined   below),   the
"Authority").

                                    RECITALS

         The  Authority  and various  affiliates  of the  Guarantor,  a New York
corporation,  have entered into a series of  agreements,  including a Management
Services  Agreement  dated  as  of  June  26,  1997  (the  "Management  Services
Agreement")  whereby Long Island  Lighting  Company,  as Manager,  has agreed to
operate,  maintain  and  manage the  Authority's  electricity  transmission  and
distribution  system (the "T&D System"),  a Power Supply  Agreement  dated as of
June 26, 1997 (the "Power Supply  Agreement"),  whereby GENCO has agreed to sell
capacity and energy to the Authority,  and an Energy Management  Agreement dated
as of June 26,  1997 (the  "Energy  Management  Agreement")  whereby  the Energy
Manager has agreed to manage the System Power  Supply and purchase  Fuel for use
in the  operation  of the  generating  facilities  of GENCO  (collectively,  the
"Agreements"), all as more particularly described therein.

         Each of the Manager,  the Energy Manager and GENCO (the "Subsidiaries")
is a subsidiary of the Guarantor.

         The  Authority  will enter into the  Agreements  only if the  Guarantor
guarantees  the  performance  by  the  Manager  of  all  of  the   Subsidiaries'
responsibilities  and  obligations  under  the  Agreements  as set forth in this
Guaranty Agreement ("the Guaranty").

         In order to induce the execution and delivery of the  Agreements by the
Authority and in consideration thereof, the Guarantor agrees as follows:

                                   ARTICLE II


                 REPRESENTATIONS AND WARRANTIES OF THE GUARANTOR


         SECTION 2.1.  REPRESENTATIONS  AND  WARRANTIES  OF THE  GUARANTOR.  The
Guarantor hereby represents and warrants that:

         (1) Existence and Powers.  The Guarantor is duly  organized and validly
existing  as a  corporation  under the laws of the State of New York,  with full
legal right, power and authority to enter into and perform its obligations under
this Guaranty.

         (2) Due  Authorization and Binding  Obligation.  The Guarantor has duly
authorized  the execution and delivery of this  Guaranty,  and this Guaranty has
been duly executed and delivered by the  Guarantor  and  constitutes  the legal,
valid and binding obligation of the Guarantor, enforceable against the Guarantor
in accordance with its terms except insofar as such  enforcement may be affected
by  bankruptcy,   insolvency,   moratorium  and  other  similar  laws  affecting
creditors' rights generally.

         (3) No Conflict.  Neither the execution or delivery by the Guarantor of
this Guaranty nor the performance by the Guarantor of its obligations  hereunder
(a) to the Guarantor's knowledge conflicts with, violates or results in a breach
of any law or governmental regulation applicable to the Guarantor, (b) conflicts
with,  violates or results in a material  breach of any term or condition of the
Guarantor's corporate charter or by-laws or any judgment,  decree,  agreement or
instrument to which the Guarantor is a party or by which the Guarantor or any of
its  properties  or assets are bound,  or  constitutes  a default under any such
judgment,  decree, agreement or instrument or (c) will result in the creation or
imposition of any material  encumbrance of any nature whatsoever upon any of the
properties  or assets of the  Guarantor  except  as  permitted  hereby or by any
Transaction Agreement.

         (4) No  Governmental  Approval  Required.  No approval,  authorization,
order  or  consent  of,  or  declaration,   registration  or  filing  with,  any
governmental  authority is required for the valid  execution and delivery by the
Guarantor  of this  Guaranty,  except  such as shall have been duly  obtained or
made.

         (5) No Litigation.  Except as disclosed in the Guarantor's filings with
the  Securities  and Exchange  Commission  pursuant to the  requirements  of the
Securities  Exchange Act of 1934, as amended,  there is no action, suit or other
proceeding,  at  law  or in  equity,  before  or by any  court  or  governmental
authority,  pending or, to the  Guarantor's  knowledge,  threatened  against the
Guarantor which has a likelihood of an unfavorable  decision,  ruling or finding
that would  materially and adversely  affect the validity or  enforceability  of
this Guaranty.


                                        4


<PAGE>

         (6)  No  Legal  Prohibition.  The  Guarantor  has no  knowledge  of any
Applicable  Law in effect on the date as of which this  representation  is being
made which would prohibit the performance by the Guarantor of this Guaranty.

         (7) Consent to Agreements. The Guarantor is fully aware of and consents
to the terms and conditions of the Agreements.

         (8) Consideration. This Guaranty is made in furtherance of the purposes
for which the Guarantor has been organized,  and the assumption by the Guarantor
of its obligations hereunder will result in a material benefit to the Guarantor.

                                   ARTICLE III


                               GUARANTY COVENANTS


         SECTION  3.1.   GUARANTY  TO  THE  AUTHORITY.   The  Guarantor   hereby
absolutely,   presently,  irrevocably  and  unconditionally  guarantees  to  the
Authority for the benefit of the Authority (1) the full and prompt  payment when
due of each and all of the  payments  required to be credited or made by each of
the Subsidiaries under the Agreements  (including all amendments and supplements
thereto) to, or for the account of, the  Authority,  and (2) the full and prompt
performance and observance of each and all of the  Obligations.  Notwithstanding
the unconditional nature of the Guarantor's obligations as set forth herein, the
Guarantor  shall have the right to assert the  defenses  provided in Section 3.4
hereof against claims made under this Guaranty.

         SECTION  3.2.  RIGHT OF AUTHORITY TO PROCEED  AGAINST  GUARANTOR.  This
Guaranty shall  constitute a guaranty of payment and of  performance  and not of
collection, and the Guarantor specifically agrees that in the event of a failure
by any Subsidiary to pay or perform any  Obligation  guaranteed  hereunder,  the
Authority  shall  have the right to  proceed  first  and  directly  against  the
Guarantor under this Guaranty and without  proceeding against such Subsidiary or
exhausting any other remedies  against such  Subsidiary  which the Authority may
have. Without limiting the foregoing,  the Guarantor agrees that it shall not be
necessary,  and that the  Guarantor  shall  not be  entitled  to  require,  as a
condition  of  enforcing  the  liability of the  Guarantor  hereunder,  that the
Authority  (1) file suit or proceed to obtain a personal  judgment  against  any
Subsidiary,  (2) make any other effort to obtain  payment or  performance of the
Obligations  from the Subsidiary  other than  providing the Subsidiary  with any
notice of such  payment or  performance  as may be  required by the terms of the
Agreements or required to be given to the Subsidiary  under  Applicable Law, (3)
foreclose  against or seek to realize upon any security for the Obligations,  or
(4)  exercise  any other  right or remedy  to which the  Authority  is or may be
entitled in  connection  with the  Obligations  or any security  therefor or any
other  guarantee  thereof,  except to the extent that any such  exercise of such
other right or remedy may be a condition to the Obligations of the  Subsidiaries
or to the  enforcement  of remedies  under the  Agreements.  Upon any  unexcused
failure by any  Subsidiary in the payment or  performance  of any Obligation and
the  giving of such  notice or demand,  if any,  to the  Subsidiaries  as may be
required in  connection  with such  Obligation,  the  liability of the Guarantor
shall be effective and shall  immediately be paid or performed.  Notwithstanding
the Authority's  right to proceed directly against the Guarantor,  the Authority
(or any successor)  shall not be entitled to more than a single full performance
of the obligations in regard to any breach or non-performance thereof.

         SECTION 3.3. GUARANTY ABSOLUTE AND  UNCONDITIONAL.  Except as set forth
in Section 3.4 hereof, the obligations of the Guarantor  hereunder are absolute,
present,


                                        6


<PAGE>

irrevocable  and  unconditional  and shall remain in full force and effect until
the Subsidiaries  shall have fully discharged the Obligations in accordance with
their respective terms, and except as provided in Section 3.4 hereof,  shall not
be subject to any counterclaim,  set-off,  deduction or defense (other than full
and strict  compliance  with,  or release,  discharge or  satisfaction  of, such
Obligations)  based  on any  claim  that the  Guarantor  may  have  against  the
Subsidiaries, the Authority or any other person. Without limiting the foregoing,
the obligations of the Guarantor hereunder shall not be released,  discharged or
in any way modified by reason of any of the  following  (whether with or without
notice to, knowledge by or further consent of the Guarantor):

               (1) the extension or renewal of this  Guaranty or the  Agreements
          in accordance with the terms of each Agreement;

               (2) any exercise or failure,  omission or delay by the  Authority
          in the  exercise  of any  right,  power  or  remedy  conferred  on the
          Authority  with respect to this Guaranty or the  Agreements  except to
          the extent such failure, omission or delay gives rise to an applicable
          statute of limitations defense with respect to a specific claim;

               (3) any permitted transfer or assignment of rights or obligations
          under the Agreements or under any other  Transaction  Agreement by any
          party  thereto  or  any  permitted  assignment,  conveyance  or  other
          transfer of any of their respective  interests in the GENCO Generating
          Facilities or the T&D System or in, to or under any of the Transaction
          Agreements;

               (4) any  permitted  assignment  for the  purpose  of  creating  a
          security  interest or  mortgage  of all or any part of the  respective
          interests  of the  Authority  or any other  person in any  Transaction
          Agreement or in the GENCO Generating Facilities or the T&D System;

               (5) any renewal,  amendment, change or modification in respect of
          any of the  Obligations  or terms  or  conditions  of any  Transaction
          Agreement;

               (6) any  failure of title with  respect to all or any part of the
          respective interests of any person in the GENCO Generating  Facilities
          or the T&D System;

               (7) the voluntary or involuntary liquidation,  dissolution,  sale
          or  other   disposition  of  all  or  substantially  all  the  assets,
          marshalling  of  assets  and  liabilities,  receivership,  insolvency,
          bankruptcy,  assignment for the benefit of creditors,  reorganization,
          moratorium,  arrangement,  composition  with creditors or readjustment
          of, or other  similar  proceedings  against  the  Subsidiaries  or the
          Guarantor, or any of the property of either of them, or any allegation
          or contest of the validity of this  Guaranty or any other  Transaction
          Agreement  in any  such  proceeding  (it is  specifically  understood,
          consented  and agreed to that,  to the extent  permitted by law,  this
          Guaranty  shall remain and continue in full force and effect and shall
          be enforceable against the Guarantor to the


                                        7


<PAGE>

          same  extent  and  with  the  same  force  and  effect  as if any such
          proceeding  had not  been  instituted  and as if no  rejection,  stay,
          termination,  assumption  or  modification  has  occurred  as a result
          thereof,  it being the intent and  purpose of this  Guaranty  that the
          Guarantor  shall and does hereby waive all rights and  benefits  which
          might accrue to it by reason of any such proceeding);

               (8) except as permitted  by Sections 4.1 or 4.2 hereof,  any sale
          or other  transfer by the  Guarantor  or any  Affiliate  of any of the
          capital  stock or other  interest of the Guarantor or any Affiliate in
          the Subsidiaries now or hereafter  owned,  directly or indirectly,  by
          the Guarantor or any  Affiliate,  or any change in  composition of the
          interests in the Subsidiaries;

               (9) any failure on the part of the Subsidiaries for any reason to
          perform or comply with any agreement with the Guarantor;

               (10) the  failure on the part of the  Authority  to  provide  any
          notice  to the  Guarantor  which  is not  required  to be given to the
          Subsidiaries as a condition to the enforcement of Obligations pursuant
          to the Agreements;

               (11) any failure of any party to the  Transaction  Agreements  to
          mitigate damages resulting from any default by the Subsidiaries or the
          Guarantor under any Transaction Agreement;

               (12) the merger or  consolidation of any party to the Transaction
          Agreements  into  or  with  any  other  person,  or any  sale,  lease,
          transfer,  abandonment  or  other  disposition  of  any  or all of the
          property of any of the foregoing to any person;

               (13) any  legal  disability  or  incapacity  of any  party to the
          Transaction Agreements; or

               (14) the fact that entering into any Transaction Agreement by the
          Subsidiaries  or the  Guarantor was invalid or in excess of the powers
          of such party.

Should any money due or owing under this  Guaranty not be  recoverable  from the
Guarantor due to any of the matters  specified in subparagraphs (1) through (14)
above, then, in any such case, such money, together with all additional sums due
hereunder,  shall  nevertheless be recoverable  from the Guarantor as though the
Guarantor were principal  obligor in place of the  Subsidiaries  pursuant to the
terms of the  Agreements  and not  merely a  guarantor  and shall be paid by the
Guarantor forthwith.  Notwithstanding anything to the contrary expressed in this
Guaranty,  nothing in this Guaranty shall be deemed to amend,  modify,  clarify,
expand or reduce the  Subsidiaries's  rights,  benefits,  duties or  obligations
under  the  Agreements.  To the  extent  that any of the  matters  specified  in
subparagraphs (1) through (6) and (8) through (14) would provide


                                        8


<PAGE>

a  defense  to,  release,  discharge  or  otherwise  affect  the  Subsidiaries's
Obligations,  the Guarantor's  obligations  under this Guaranty shall be treated
the same.

         SECTION 3.4. DEFENSES, SET-OFFS AND COUNTERCLAIMS.  Notwithstanding any
provision  contained herein to the contrary,  the Guarantor shall be entitled to
exercise or assert any and all legal or equitable  rights or defenses  which the
Subsidiaries  may have under the Agreements or under  Applicable Law (other than
bankruptcy or insolvency  of the  Subsidiaries  and other than any defense which
the Subsidiaries has expressly waived in the Agreements), and the obligations of
the  Guarantor  hereunder  are  subject  to  such  counterclaims,   set-offs  or
deductions  which  the  Subsidiaries  is  permitted  to assert  pursuant  to the
Agreements if any. The Guarantor  reserves the right to bring independent claims
against the Authority not arising from the  Agreements,  provided  however,  any
such  claims  shall not be used to set-off or deduct  from any claims  which the
Authority may have against the Guarantor arising from this Guaranty.

         SECTION  3.5.   WAIVERS  BY  THE   GUARANTOR.   The  Guarantor   hereby
unconditionally and irrevocably waives:

               (1) notice from the Authority of its acceptance of this Guaranty;

               (2) notice of any of the events referred to in Section 3.3 hereof
          except  to the  extent  that  notice  is  required  to be  given  as a
          condition to the enforcement of Obligations;

               (3) to the fullest extent  lawfully  possible,  all notices which
          may be  required  by  statute,  rule of law or  otherwise  to preserve
          intact  any rights  against  the  Guarantor,  except any notice to the
          Subsidiaries  required pursuant to the Agreements or Applicable Law as
          a condition to the performance of any Obligation;

               (4) to the  fullest  extent  lawfully  possible,  any  statute of
          limitations defense based on a statute of limitations period which may
          be  applicable  to  guarantors  (or parties in similar  relationships)
          which  would be shorter  than the  applicable  statute of  limitations
          period for the underlying claim;

               (5)  any  right  to  require  a  proceeding   first  against  the
          Subsidiaries;

               (6) any right to require a proceeding first against any person or
          the security provided by or under any Transaction  Agreement except to
          the  extent  such  Transaction   Agreement   specifically  requires  a
          proceeding  first  against  any person  (except the  Subsidiaries)  or

          other   formalities  the  omission  of  any  of  which,  or  delay  in
          performance  of which,  might,  but for the provisions of this Section
          3.5, by rule of law or otherwise,  constitute grounds for relieving or
          discharging  the  Guarantor  in  whole or in part  from its  absolute,
          present,   irrevocable,   unconditional  and  continuing   obligations
          hereunder.

         SECTION 3.6. PAYMENT OF COSTS AND EXPENSES. The Guarantor agrees to pay

agreements  and  obligations  contained in this Guaranty  against the Guarantor,

obligations of the Guarantor from its other obligations under this Guaranty, (2)
give rise to separate and independent causes of action against the Guarantor and
(3)  apply  irrespective  of any  indulgence  granted  from  time to time by the
Authority.  The  Guarantor  agrees  that this  Guaranty  shall be  automatically
reinstated  if and to the extent that for any reason any payment by or on behalf
of the Subsidiaries is rescinded or must be otherwise restored by the Authority,
whether as a result of any proceedings in bankruptcy,  reorganization or similar
proceeding,  unless such  rescission or  restoration is pursuant to the terms of
the Agreements,  or any applicable  Transaction  Agreement or the Subsidiaries's
enforcement of such terms under Applicable Law.

         SECTION 3.9. TERM.  This Guaranty shall remain in full force and effect
from the date of execution and delivery  hereof until all of the  Obligations of

                                GENERAL COVENANTS


         SECTION 4.1.  MAINTENANCE OF CORPORATE  EXISTENCE.  (A)  Consolidation,
Merger,  Sale or Transfer.  The Guarantor covenants that during the term of this
Guaranty  it will  maintain  its  corporate  existence,  will  not  dissolve  or
otherwise  dispose  of all or  substantially  all of its  assets  and  will  not
consolidate  with or merge  into  another  entity  or permit  one or more  other
entities  to  consolidate  with or merge  into it unless  the  successor  is the
Guarantor  and the  conditions  contained  in clause  (2)  below are  satisfied;
provided, however, that the Guarantor may consolidate with or merge into another
entity,  or permit one or more other entities to consolidate  with or merge into
it, or sell or otherwise  transfer to another entity all or substantially all of
its assets as an entirety and  thereafter  dissolve if (1) the successor  entity
(if other than the Guarantor) (a) assumes in writing all the  obligations of the
Guarantor hereunder and, if required by law, is duly qualified to do business in
the State, and (b) delivers to the Authority an opinion of counsel to the effect
that  its  obligations  under  this  Guaranty  are  legal,  valid,  binding  and
enforceable   subject  to  applicable   bankruptcy  and  similar  insolvency  or
moratorium  laws,  and (2) any such  transaction  does not  result in a Material
Decline in Credit  Standing of the  Guarantor,  as defined in Section 9.1 of the
Management  Services  Agreement  or if such  transaction  results  in a Material
Decline in Credit  Standing of the  Guarantor,  as defined in Section 9.1 of the

consolidation,  merger  or sale or  other  transfer  shall  be  made  except  in
compliance  with the  provisions  of this  Section  4.1. No such  consolidation,
merger or sale or other  transfer shall have the effect of releasing the initial
Guarantor  from its liability  hereunder  unless a successor  entity has assumed
responsibility  for this  Guaranty as provided in this  Section 4.1. and if such
transaction results in a Material Decline in Credit Standing of the Guarantor as
defined in Section  9.1 of the  Management  Services  Agreement,  the  Successor
Guarantor  shall provide  credit  enhancement  as required by Section 9.1 of the
Management Services Agreement.

successors and assigns.

be waived,  except with the prior  written  consent of the  Authority and of the
Guarantor.

         SECTION 4.7. LIABILITY. It is understood and agreed to by the Authority
that nothing contained herein shall create any obligation of or right to look to
any  director,  officer,  employee  or  stockholder  of the  Guarantor  (or  any
affiliate  thereof) for the  satisfaction of any obligations  hereunder,  and no
judgment, order or execution with respect to or in connection with this Guaranty

entitled to control  the  handling of any such claim and to defend or settle any
such claim,  in its or their sole  discretion,  with counsel of its own choosing
that is reasonably acceptable to the Indemnified Party; provided, however, that,
in the case of any such settlement,  the Indemnifying Party shall obtain written
release  of all  liability  of the  Indemnified  Party,  in form  and  substance
reasonably  acceptable to the Indemnified Party.  Notwithstanding the foregoing,
each  Indemnified  Party shall have the right to employ its own separate counsel
in connection  with, and to participate in (but,  except as provided below,  not
control)  the defense of, such claim,  but the fees and expenses of such counsel
incurred  after  notice from the  Indemnifying  Party of its  assumption  of the
defense thereof shall be at the expense of such Indemnified Party unless:

          (i)  the  employment  of  counsel by such  Indemnified  Party has been
               authorized by the Indemnifying Party;

          (ii) counsel to such Indemnified Party shall have reasonably concluded
               that there may be a conflict on any significant issue between the
               Indemnifying  Party and such Indemnified  Party in the conduct of
               the defense of such claim; or

          (iii) the Indemnifying  Party shall not in fact have employed  counsel
               reasonably  acceptable  to the  Indemnified  Party to assume  the
               defense of such  claim  within  twenty  (20) days  following  the
               receipt by the Indemnifying  Party of the notice specified in the
               first  sentence of this Section  6(b), in each of which cases the
               fees and expenses of counsel for such Indemnified  Party shall be
               at the expense of the Indemnifying Party;

provided,  however,  that,  with  respect  to  clauses  (ii)  and  (iii) of this
sentence,  the  Indemnifying  Party shall not be  obligated  to pay the fees and
expenses  of more than one law firm,  plus local  counsel if  necessary  in each
relevant  jurisdiction,  for all such  Indemnified  Parties  with respect to any
claims  arising  out of the same events or facts or the same series of events or
facts. The Indemnifying Party shall not be entitled, without the consent of such
Indemnified  Party,  to assume or control  the  defense of any claim as to which
counsel to such Indemnified Party shall have reasonably made the conclusion that
there may be a conflict on any significant issue between the Indemnifying  Party
and such  Indemnified  Party in the  conduct of the defense of such claim as set
forth in clause (ii) above,  provided that the foregoing  limitation shall apply
only with respect to those issues for which there may be such a conflict.

         7. This  Undertaking  shall be governed by the laws of the State of New
York. Any dispute with respect to the interpretation or enforcement hereof shall
be submitted to an alternative dispute resolution  procedure to be agreed by the
