SECTION 2.01.  FORM AND DATING.

         (a) General. The Bonds and the Trustee's certificate of authentication
shall be substantially in the form of Exhibit A hereto. The Bonds may have
notations, legends or endorsements required by law, stock exchange rule or
usage. Each Bond shall be dated the date of its authentication. The Bonds shall
be in denominations of $100,000 and integral multiples of $1,000 in excess
thereof.

         The terms and provisions contained in the Bonds shall constitute, and
are hereby expressly made, a part of this Indenture and the Company, the Bond
Guarantor, NE LLC and the Trustee, by their execution and delivery of this
Indenture, expressly agree to such terms and provisions and to be bound thereby.
However, to the extent any provision of any Bond conflicts with the express
provisions of this Indenture, the provisions of this Indenture shall govern and
be controlling.

         (b) Global Bonds. Bonds issued in global form shall be substantially in
the form of Exhibits A-1 or A-2 attached hereto (including the Global Bond
Legend thereon and the "Schedule of Exchanges of Interests in the Global Bond"
attached thereto). Bonds issued in definitive form shall be substantially in the
form of Exhibit A-1 attached hereto (but without the Global Bond Legend thereon
and without the "Schedule of Exchanges of Interests in the Global Bond" attached
thereto). Each Global Bond shall represent such of the outstanding Bonds as
shall be specified therein and each shall provide that it shall represent the

                                       14


aggregate principal amount of outstanding Bonds from time to time endorsed
thereon and that the aggregate principal amount of outstanding Bonds represented
thereby may from time to time be reduced or increased, as appropriate, to
reflect exchanges and redemptions. Any endorsement of a Global Bond to reflect
the amount of any increase or decrease (other than in connection with any
scheduled payment of principal) in the aggregate principal amount of outstanding
Bonds represented thereby shall be made by the Trustee or the Bond Custodian, at
the direction of the Trustee, in accordance with instructions given by the
Holder thereof as required by Section 2.06 hereof.

         (c) Temporary Global Bonds. Bonds offered and sold in reliance on
Regulation S shall be issued initially in the form of the Regulation S Temporary
Global Bond, which shall be deposited on behalf of the purchasers of the Bonds
represented thereby with the Trustee, at its New York office, as custodian for
the Depositary, and registered in the name of the Depositary or the nominee of
the Depositary for the accounts of designated agents holding on behalf of
Euroclear or Cedel Bank, duly executed by the Company and authenticated by the
Trustee as hereinafter provided. The Restricted Period shall be terminated upon
the receipt by the Trustee of (i) a written certificate from the Depositary,
together with copies of certificates from Euroclear and Cedel Bank certifying
that they have received certification of non-United States beneficial ownership
of 100% of the aggregate principal amount of the Regulation S Temporary Global
Bond (except to the extent of any beneficial owners thereof who acquired an
interest therein during the Restricted Period pursuant to another exemption from
registration under the Securities Act and who will take delivery of a beneficial
ownership interest in a 144A Global Bond bearing a Private Placement Legend, all
as contemplated by Section 2.06(a)(ii) hereof), and (ii) an Officers'
Certificate from the Company to the effect that such Restricted Period has
ended. Following the termination of the Restricted Period, beneficial interests
in the Regulation S Temporary Global Bond shall be exchanged for beneficial
interests in Regulation S Permanent Global Bonds pursuant to the Applicable
Procedures. Simultaneously with the authentication of Regulation S Permanent
Global Bonds, the Trustee shall cancel the Regulation S Temporary Global Bond.
The aggregate principal amount of the Regulation S Temporary Global Bond and the
Regulation S Permanent Global Bonds may from time to time be increased or
decreased by adjustments made on the records of the Trustee and the Depositary
or its nominee, as the case may be, in connection with transfers of interest as
hereinafter provided.

         (d) Euroclear and Cedel Procedures Applicable. Provided that neither
the Company nor the Trustee shall be required to take notice of any such
provision, the provisions of the "Operating Procedures of the Euroclear System"
and "Terms and Conditions Governing Use of Euroclear" and the "General Terms and
Conditions of Cedel Bank" and "Customer Handbook" of Cedel Bank shall be
applicable to transfers of beneficial interests in the Regulation S Temporary
Global Bond and the Regulation S Permanent Global Bonds that are held by
Participants through Euroclear or Cedel Bank.

SECTION 2.02. EXECUTION AND AUTHENTICATION. Two Officers shall sign the Bonds
for the Company by manual or facsimile signature. The Company's seal shall be
reproduced on the Bonds and may be in facsimile form.

         If one or both Officers whose signature are on a Bond no longer hold
that office at the time a Bond is authenticated, the Bond shall nevertheless be
valid.

         A Bond shall not be valid until authenticated by the manual signature
of the Trustee. The signature shall be conclusive evidence that the Bond has
been authenticated under this Indenture.

         The Trustee shall, upon (i) a written order of the Company signed by
one or both Officers (an "Authentication Order") accompanied by the documents
required pursuant to Section 13.04, (ii) the initial deposit of cash or
Acceptable Credit Support pursuant to Section 10.04, (iii) the execution and
delivery by the parties thereto of the Pledge Agreements and (iv) delivery to
the Trustee of evidence of receipt by the Collateral Agent of the Pledge
Agreements, the Pledged Shares and the Pledged Note, authenticate Bonds for
original issue up to the aggregate principal amount stated in paragraph 4 of the
Bonds. The aggregate principal amount of Bonds outstanding at any time may not
exceed such amount except as provided in Section 2.07 hereof.

         The Trustee may appoint an authenticating agent acceptable to the
Company to authenticate Bonds. An authenticating agent may authenticate Bonds
whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent. An
authenticating agent has the same rights as an Agent to deal with Holders or an
Affiliate of the Company.

SECTION 2.03. REGISTRAR AND PAYING AGENT. The Company shall maintain or cause to
be maintained an office or agency where Bonds may be presented for registration
of transfer or for exchange ("Registrar") and shall appoint an institution with
trust powers to maintain an office or agency where Bonds may be presented for
payment ("Paying Agent"). The Registrar shall keep a register of the Bonds and
of their transfer and exchange. The Company may appoint one or more
co-registrars and one or more additional paying agents. The term "Registrar"
includes any co-registrar and the term "Paying Agent" includes any additional
paying agent. The Company may change any Paying Agent or Registrar without
notice to any Holder. The Company shall notify the Trustee in writing of the
name and address of any Agent not a party to this Indenture. If the Company
fails to appoint or maintain another entity as Registrar or Paying Agent, the
Trustee shall act as such. The Company or NE LP may act as Registrar but shall
not act as Paying Agent.

         The Company initially appoints The Depository Trust Company ("DTC") to
act as Depositary with respect to the Global Bonds.

         The Company initially appoints the Trustee to act as the Registrar and
Paying Agent and to act as Bond Custodian with respect to the Global Bonds.

                                       16


SECTION 2.04. PAYING AGENT TO HOLD MONEY IN TRUST.

         The Company shall require each Paying Agent other than the Trustee to
agree in writing that the Paying Agent will hold in trust for the benefit of
Holders or the Trustee all money held by the Paying Agent for the payment of
principal, premium or Registration Default Damages, if any, or interest on the
Bonds, and will notify the Trustee of any default by the Company in making any
such payment. While any such default continues, the Trustee may require a Paying
Agent to pay all money held by it to the Trustee. The Company at any time may
require a Paying Agent to pay all money held by it to the Trustee. Upon payment
over to the Trustee, the Paying Agent shall have no further liability for the
money.

SECTION 2.05. HOLDER LISTS.

         The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
all Holders and shall otherwise comply with TIA ss. 312(a). If the Trustee is
not the Registrar, the Company shall furnish to the Trustee at least seven
Business Days before each interest payment date and at such other times as the
Trustee may request in writing, a list in such form and as of such date as the
Trustee may reasonably require of the names and addresses of the Holders of
Bonds and the Company shall otherwise comply with TIA ss. 312(a).

SECTION 2.06. TRANSFER AND EXCHANGE.

         (a) Transfer and Exchange of Global Bonds. A Global Bond may not be
transferred as a whole except by the Depositary to a nominee of the Depositary,
by a nominee of the Depositary to the Depositary or to another nominee of the
Depositary, or by the Depositary or any such nominee to a successor Depositary
or a nominee of such successor Depositary. All Global Bonds will be exchanged by
the Company for Definitive Bonds if (i) the Company or the Depositary delivers
to the Trustee notice from the Depositary that it is unwilling or unable to
continue to act as Depositary or that it is no longer a clearing agency
registered under the Exchange Act and, in either case, a successor Depositary is
not appointed by the Company within 90 days after the date of such notice from
the Depositary or (ii) the Company in its sole discretion determines that the
Global Bonds (in whole but not in part) should be exchanged for Definitive Bonds
and delivers a written notice to such effect to the Trustee; provided that in no
event shall the Regulation S Temporary Global Bond be exchanged by the Company
for Definitive Bonds prior to (x) the expiration of the Restricted Period and
(y) the receipt by the Registrar of any certificates required pursuant to Rule
903(c)(3)(ii)(B) under the Securities Act. Upon the occurrence of either of the
preceding events described in (i) or (ii) above, Definitive Bonds shall be
issued in such names as the Depositary shall instruct the Trustee. Global Bonds
also may be exchanged or replaced, in whole or in part, as provided in Sections
2.07 and 2.10 hereof. Except as otherwise provided in this Section 2.06(a) every
Bond authenticated and delivered in exchange for, or in lieu of, a Global Bond
or any portion thereof, pursuant to this Section 2.06 or Section 2.07 or 2.10
hereof, shall be authenticated and delivered in the form of, and shall be, a
Global Bond. A Global Bond may not be exchanged for another Bond other than as

                                       17


provided in this Section 2.06(a); however, beneficial interests in a Global Bond
may be transferred and exchanged as provided in Section 2.06(b),(c) or (f)
hereof.

         (b) Transfer and Exchange of Beneficial Interests in the Global Bonds.
The transfer and exchange of beneficial interests in the Global Bonds shall be
effected through the Depositary, in accordance with the provisions of this
Indenture and the Applicable Procedures. Beneficial interests in the Restricted
Global Bonds shall be subject to restrictions on transfer comparable to those
set forth herein to the extent required by the Securities Act. Transfers of
beneficial interests in the Global Bonds also shall require compliance with
either subparagraph (i) or (ii) below, as applicable, as well as one or more of
the other following subparagraphs, as applicable:

                  (i) Transfer of Beneficial Interests in the Same Global Bond.
         Beneficial interests in any Restricted Global Bond may be transferred
         to Persons who take delivery thereof in the form of a beneficial
         interest in the same Restricted Global Bond in accordance with the
         transfer restrictions set forth in the Private Placement Legend;
         provided, however, that prior to the expiration of the Restricted
         Period, transfers of beneficial interests in the Temporary Regulation S
         Global Bond may not be made to a U.S. Person or for the account or
         benefit of a U.S. Person (other than the Purchaser). Beneficial
         interests in any Unrestricted Global Bond may be transferred to Persons
         who take delivery thereof in the form of a beneficial interest in an
         Unrestricted Global Bond. No written orders or instructions shall be
         required to be delivered to the Registrar to effect the transfers
         described in this Section 2.06(b)(i).

                  (ii) All Other Transfers and Exchanges of Beneficial Interests
         in Global Bonds. In connection with all transfers and exchanges of
         beneficial interests that are not subject to Section 2.06(b)(i) above,
         the transferor of such beneficial interest must deliver to the
         Registrar either (A) (1) a written order from a Participant or an
         Indirect Participant given to the Depositary in accordance with the
         Applicable Procedures directing the Depositary to credit or cause to be
         credited a beneficial interest in another Global Bond in an amount
         equal to the beneficial interest to be transferred or exchanged and (2)
         instructions given in accordance with the Applicable Procedures
         containing information regarding the Participant account to be credited
         with such increase or (B) (1) a written order from a Participant or an
         Indirect Participant given to the Depositary in accordance with the
         Applicable Procedures directing the Depositary to cause to be issued a
         Definitive Bond in an amount equal to the beneficial interest to be
         transferred or exchanged and (2) instructions given by the Depositary
         to the Registrar containing information regarding the Person in whose
         name such Definitive Bond shall be registered to effect the transfer or
         exchange referred to in (1) above; provided that in no event shall
         Definitive Bonds be issued upon the transfer or exchange of beneficial
         interests in the Regulation S Temporary Global Bond prior to (x) the
         expiration of the Restricted Period and (y) the receipt by the
         Registrar of any certificates required pursuant to Rule 903 under the
         Securities Act. Upon consummation of an Exchange Offer by the Company
         in accordance with Section 2.06(f) hereof, the requirements of this

                                       18


         Section 2.06(b)(ii) shall be deemed to have been satisfied upon receipt
         by the Registrar of the instructions contained in the Letter of
         Transmittal delivered by the Holder of such beneficial interests in the
         Restricted Global Bonds. Upon satisfaction of all of the requirements
         for transfer or exchange of beneficial interests in Global Bonds
         contained in this Indenture and the Bonds or otherwise applicable under
         the Securities Act, the Trustee shall adjust the principal amount of
         the relevant Global Bond(s) pursuant to Section 2.06(h) hereof.

                  (iii) Transfer of Beneficial Interests to Another Restricted
         Global Bond. A beneficial interest in any Restricted Global Bond may be
         transferred to a Person who takes delivery thereof in the form of a
         beneficial interest in another Restricted Global Bond if the transfer
         complies with the requirements of Section 2.06(b)(ii) above and the
         Registrar receives the following:

                  (A) if the transferee will take delivery in the form of a
              beneficial interest in the 144A Global Bond, then the transferor
              must deliver a certificate in the form of Exhibit B hereto,
              including the certifications in item (1) thereof; and

                  (B) if the transferee will take delivery in the form of a
              beneficial interest in the Regulation S Temporary Global Bond or
              the Regulation S Global Bond, then the transferor must deliver a
              certificate in the form of Exhibit B hereto, including the
              certifications in item (2) thereof.

                  (iv) Transfer and Exchange of Beneficial Interests in a
         Restricted Global Bond for Beneficial Interests in the Unrestricted
         Global Bond. A beneficial interest in any Restricted Global Bond may be
         exchanged by any holder thereof for a beneficial interest in an
         Unrestricted Global Bond or transferred to a Person who takes delivery
         thereof in the form of a beneficial interest in an Unrestricted Global
         Bond if the exchange or transfer complies with the requirements of
         Section 2.06(b)(ii) above and:

                  (A) such exchange or transfer is effected pursuant to the
              Exchange Offer in accordance with the Registration Rights
              Agreement and the holder of the beneficial interest to be
              transferred, in the case of an exchange, or the transferee, in the
              case of a transfer, certifies in the applicable Letter of
              Transmittal that it is not (1) a broker-dealer, (2) a Person
              participating in the distribution of the Exchange Bonds or (3) a
              Person who is an affiliate (as defined in Rule 144) of the
              Company; or

                  (B) such transfer is effected pursuant to the Shelf
              Registration Statement in accordance with the Registration Rights
              Agreement; or

                  (C) such transfer is effected by a Participating Broker-Dealer
              pursuant to the Exchange Offer Registration Statement in
              accordance with the Registration Rights Agreement; or

                  (D) the Registrar receives the following:

                                       19


                      (1) if the holder of such beneficial interest in a
         Restricted Global Bond proposes to exchange such beneficial interest
         for a beneficial interest in an Unrestricted Global Bond, a certificate
         from such holder in the form of Exhibit C hereto, including the
         certifications in item (1)(a) thereof; or

                      (2) if the holder of such beneficial interest in a
         Restricted Global Bond proposes to transfer such beneficial interest to
         a Person who shall take delivery thereof in the form of a beneficial
         interest in an Unrestricted Global Bond, a certificate from such holder
         in the form of Exhibit B hereto, including the certifications in item
         (4) thereof;

         Registrar so requests or if the Applicable Procedures so require, an
         Opinion of Counsel in form reasonably acceptable to the Registrar to
         the effect that such exchange or transfer is in compliance with the
         Securities Act and that the restrictions on transfer contained herein
         and in the Private Placement Legend are no longer required in order to
         maintain compliance with the Securities Act.

         If any such transfer is effected pursuant to subparagraph (B) or (D)
above at a time when an Unrestricted Global Bond has not yet been issued, the
Company shall issue and, upon receipt of an Authentication Order in accordance
with Section 2.02 hereof, the Trustee shall authenticate one or more
Unrestricted Global Bonds in an aggregate principal amount equal to the
aggregate principal amount of beneficial interests transferred pursuant to
subparagraph (B) or (D) above.

         Beneficial interests in an Unrestricted Global Bond cannot be exchanged
for, or transferred to Persons who take delivery thereof in the form of, a
beneficial interest in a Restricted Global Bond.

         (c) Transfer or Exchange of Beneficial Interests for Definitive Bonds.

         for a Restricted Definitive Bond or to transfer such beneficial
         interest to a Person who takes delivery thereof in the form of a
         Restricted Definitive Bond, then, upon receipt by the Registrar of the

         such name or names and in such authorized denomination or denominations
         as the holder of such beneficial interest shall instruct the Registrar
         through instructions from the Depositary and the Participant or

         and in such authorized denomination or denominations as the holder of
         such beneficial interest shall instruct the Registrar through
         instructions from the Depositary and the Participant or Indirect

         Bond issued in exchange for a beneficial interest pursuant to this
         Section 2.06(c)(iii) shall not bear the Private Placement Legend.

Bond shall be reduced accordingly and an endorsement shall be made on such
Global Bond by the Trustee or by the Depositary at the direction of the Trustee
to reflect such reduction; and if the beneficial interest is being exchanged for
or transferred to a Person who will take delivery thereof in the form of a
beneficial interest in another Global Bond, such other Global Bond shall be
increased accordingly and an endorsement shall be made on such Global Bond by
the Trustee or by the Depositary at the direction of the Trustee to reflect such
increase.

         (i) General Provisions Relating to Transfers and Exchanges.

                  (i) To permit registrations of transfers and exchanges, the
         Company shall execute and the Trustee shall authenticate Global Bonds
         and Definitive Bonds upon the Company's order or at the Registrar's
         request.

                  (ii) No service charge shall be made to a holder of a
         beneficial interest in a Global Bond or to a Holder of a Definitive
         Bond for any registration of transfer or exchange, but the Company may
         require payment of a sum sufficient to cover any transfer tax or
         similar governmental charge payable in connection therewith (other than
         any such transfer taxes or similar governmental charge payable upon
         exchange or transfer pursuant to Sections 2.10, 3.06, 4.15 and 9.05
         hereof).

                  (iii) The Registrar shall not be required to register the
         transfer of or exchange any Bond selected for redemption in whole or in
         part, except the unredeemed portion of any Bond being redeemed in part.

                  (iv) All Global Bonds and Definitive Bonds issued upon any
         registration of transfer or exchange of Global Bonds or Definitive
         Bonds shall be the valid obligations of the Company, evidencing the
         same debt, and entitled to the same benefits under this Indenture, as
         the Global Bonds or Definitive Bonds surrendered upon such registration
         of transfer or exchange.

                                       29


                  (v) The Company shall not be required (A) to issue, to
         register the transfer of or to exchange any Bonds during a period
         beginning at the opening of business 15 days before the day of any
         selection of Bonds for redemption under Section 3.02 hereof and ending
         at the close of business on the day of selection, (B) to register the
         transfer of or to exchange any Bond so selected for redemption in whole
         or in part, except the unredeemed portion of any Bond being redeemed in
         part or (c) to register the transfer of or to exchange a Bond between a
         record date and the next succeeding Interest Payment Date.

                  (vi) The Trustee, any Agent and the Company may deem and treat
         the Person in whose name any Bond is registered as the absolute owner
         of such Bond for the purpose of receiving payment of principal of and
         interest on such Bonds and for all other purposes, and none of the
         Trustee, any Agent or the Company shall be affected by notice to the
         contrary.

                  (vii) The Trustee shall authenticate Global Bonds and
         Definitive Bonds in accordance with the provisions of Section 2.02
         hereof.

                  (viii) All certifications, certificates and Opinions of
         Counsel required to be submitted to the Registrar pursuant to this
         Section 2.06 to effect a registration of transfer or exchange may be
         submitted by facsimile.

SECTION 2.07.  REPLACEMENT BONDS

         If any mutilated Bond is surrendered to the Trustee or the Company and
the Trustee receives evidence to its satisfaction of the destruction, loss or
theft of any Bond, the Company shall issue and the Trustee, upon receipt of an
Authentication Order, shall authenticate a replacement Bond if the Trustee's
requirements are met. If required by the Trustee or the Company, an indemnity
bond must be supplied by the Holder that is sufficient in the judgment of the
Trustee and the Company to protect the Company, the Trustee, any Agent and any
authenticating agent from any loss that any of them may suffer if a Bond is
replaced. The Company may charge for its expenses in replacing a Bond.

         Every replacement Bond is an additional obligation of the Company and
shall be entitled to all of the benefits of this Indenture equally and
proportionately with all other Bonds duly issued hereunder.

SECTION 2.08.  OUTSTANDING BONDS.

         The Bonds outstanding at any time are all the Bonds authenticated by
the Trustee except for those canceled by it, those delivered to it for
cancellation, those reductions in the interest in a Global Bond effected by the
Trustee in accordance with the provisions hereof, and those described in this
Section as not outstanding. Except as set forth in Section 2.09 hereof, a Bond
does not cease to be outstanding because the Company or an Affiliate of the
Company holds the Bond.

                                       30



         If a Bond is replaced pursuant to Section 2.07 hereof, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Bond is held by a bona fide purchaser.

         If the principal amount of any Bond or portion thereof is considered
paid under Section 4.01 hereof, it ceases to be outstanding and interest on it
ceases to accrue.

         If the Paying Agent (other than the Company, a Subsidiary or an
Affiliate of any thereof) holds, on a redemption date or maturity date, money
sufficient to pay Bonds payable on that date, then on and after that date such
Bonds shall be deemed to be no longer outstanding and shall cease to accrue
interest.

SECTION 2.09. TREASURY BONDS.

         In determining whether the Holders of the required principal amount of
Bonds have concurred in any direction, waiver or consent, Bonds owned by the
Company, or by any Person directly or indirectly controlling or controlled by or
under direct or indirect common control with the Company, shall be considered as
though not outstanding, except that for the purposes of determining whether the
Trustee shall be protected in relying on any such direction, waiver or consent,
only Bonds that the Trustee knows are so owned shall be so disregarded.

SECTION 2.10. TEMPORARY BONDS

         Until certificates representing Bonds are ready for delivery, the
Company may prepare and the Trustee, upon receipt of an Authentication Order,
shall authenticate temporary Bonds. Temporary Bonds shall be substantially in
the form of certificated Bonds but may have variations that the Company
considers appropriate for temporary Bonds and as shall be reasonably acceptable
to the Trustee. Without unreasonable delay, the Company shall prepare and the
Trustee shall authenticate definitive Bonds in exchange for temporary Bonds.

         Holders of temporary Bonds shall be entitled to all of the benefits of
this Indenture.

SECTION 2.11. CANCELLATION.

         The Company at any time may deliver Bonds to the Trustee for
cancellation. The Registrar and Paying Agent shall forward to the Trustee any
Bonds surrendered to them for registration of transfer, exchange or payment. The
Trustee and no one else shall cancel all Bonds surrendered for registration of
transfer, exchange, payment, replacement or cancellation and shall destroy
canceled Bonds (subject to the record retention requirement of the Exchange
Act). Certification of the destruction of all canceled Bonds shall be delivered
to the Company. The Company may not issue new Bonds to replace Bonds that it has
paid or that have been delivered to the Trustee for cancellation.

                                       31


SECTION 2.12. DEFAULTED INTEREST.

         If the Company defaults in a payment of interest on the Bonds, it shall
pay the defaulted interest in any lawful manner plus, to the extent lawful,
interest payable on the defaulted interest, to the Persons who are Holders on a
subsequent special record date, in each case at the rate provided in the Bonds
and in Section 4.01 hereof. The Company shall notify the Trustee in writing of
the amount of defaulted interest proposed to be paid on each Bond and the date
of the proposed payment. The Company shall fix or cause to be fixed each such
special record date and payment date, provided that no such special record date
shall be less than 10 days prior to the related payment date for such defaulted
interest. At least 15 days before the special record date, the Company (or, upon
the written request of the Company, the Trustee in the name and at the expense
of the Company) shall mail or cause to be mailed to Holders a notice that states
the special record date, the related payment date and the amount of such
interest to be paid.

                            REDEMPTION AND PREPAYMENT

SECTION 3.01.  NOTICES TO TRUSTEE.

         If the Company elects to redeem Bonds pursuant to the optional
redemption provisions of Section 3.07 hereof, it shall furnish to the Trustee,
at least 40 days but not more than 70 days before a redemption date, an
Officers' Certificate setting forth (i) the clause of this Indenture pursuant to
which the redemption shall occur, (ii) the redemption date, (iii) the principal
amount of Bonds to be redeemed and (iv) the redemption price including
Registration Default Damages, if any.

SECTION 3.02.  SELECTION OF BONDS TO BE REDEEMED OR REPURCHASED

         Subject to the book entry system described herein, if less than all of
the Bonds are to be redeemed or purchased in an offer to purchase at any time,
the Trustee shall select the Bonds to be redeemed or purchased in compliance
with the requirements of the principal national securities exchange, if any, on
which the Bonds are listed or, if the Bonds are not so listed, on a pro rata
basis or by such other method as the Trustee considers fair and appropriate;
provided that, except in the case of an extraordinary mandatory redemption, no
Bonds will be redeemed in part if the unredeemed portion will be in an
unauthorized denomination. Subject to the book-entry system, in the event of
partial redemption by lot, the particular Bonds to be redeemed shall be
selected, unless otherwise provided herein, not less than 35 nor more than 60
days prior to the redemption date by the Trustee from the outstanding Bonds not
previously called for redemption.

         The Trustee shall promptly notify the Registrar and the Paying Agent in
writing of the Bonds selected for redemption and, in the case of any Bond
selected for partial redemption, the principal amount thereof to be redeemed.
Bonds and portions of Bonds selected shall be in amounts of $100,000 or whole
multiples of $1,000 in excess thereof; except that if all of the Bonds of a
Holder are to be redeemed, the entire outstanding amount of Bonds held by such
Holder, even if not a multiple of $100,000 or a multiple of $1,000 in excess
thereof, shall be redeemed. Except as provided in the preceding sentence,

                                       32


provisions of this Indenture that apply to Bonds called for redemption also
apply to portions of Bonds called for redemption.

SECTION 3.03.  NOTICE OF REDEMPTION

         At least 30 days but not more than 60 days before a redemption date,
the Registrar shall mail or cause to be mailed, by first class mail, a notice of
redemption to each Holder whose Bonds are to be redeemed at its registered
address.

         The notice shall identify the Bonds to be redeemed and shall state:

         (a) the redemption date;

         (b) the redemption price including any Registration Default Damages;

         (c) if any Bond is being redeemed in part, the portion of the principal
amount of such Bond to be redeemed and that, after the redemption date upon
surrender of such Bond, a new Bond or Bonds in principal amount equal to the
unredeemed portion shall be issued in the name of the Holder thereof upon
cancellation of the original Bond;

         (d) the name and address of the Paying Agent;

         (e) that Bonds called for redemption must be surrendered to the Paying
Agent to collect the redemption price;

         (f) that, unless the Company defaults in making such redemption
payment, interest on Bonds called for redemption ceases to accrue on and after
the date fixed for redemption;

         (g) the paragraph of the Bonds and/or Section of this Indenture
pursuant to which the Bonds called for redemption are being redeemed; and

         (h) the CUSIP number and that no representation is made as to the
correctness or accuracy of the CUSIP number, if any, listed in such notice or
printed on the Bonds.

         At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at its expense; provided, however, that the
Company shall have delivered to the Trustee, at least 45 days prior to the
redemption date, an Officers' Certificate requesting that the Trustee give such
notice and setting forth the information to be stated in such notice as provided
in the preceding paragraph.

SECTION 3.04.  EFFECT OF NOTICE OF REDEMPTION

         Once notice of redemption is mailed in accordance with Section 3.03
hereof, Bonds called for redemption become irrevocably due and payable on the
date fixed for redemption at the redemption price. A notice of redemption may
not be conditional.

                                       33


SECTION 3.05.   DEPOSIT OF REDEMPTION PRICE

         No later than one Business Day prior to the redemption date, the
Company shall deposit with the Trustee or with the Paying Agent money
sufficient, together with moneys then held by the Trustee, to pay the redemption
price of and accrued interest on all Bonds to be redeemed on that date. The
Trustee or the Paying Agent shall promptly return to the Company any money
deposited with the Trustee or the Paying Agent by the Company in excess of the
amounts necessary to pay the redemption price of, and accrued interest on, all
Bonds to be redeemed.

         If the Company complies with the provisions of the preceding paragraph,
on and after the date fixed for redemption, interest shall cease to accrue on
the Bonds or the portions of Bonds redeemed. If a Bond is redeemed on or after
an interest record date but on or prior to the related interest payment date,
then any accrued and unpaid interest shall be paid to the Person in whose name
such Bond was registered at the close of business on such record date. If any
Bond called for redemption shall not be so paid upon surrender for redemption
because of the failure of the Company to comply with the preceding paragraph,
interest shall be paid on the unpaid principal, from the redemption date until
such principal is paid, and to the extent lawful on any interest not paid on
such unpaid principal, in each case at the rate provided in the Bonds and in
Section 4.01 hereof.

SECTION 3.06.   BONDS REDEEMED IN PART.

         Upon surrender of a Bond that is redeemed in part, the Company shall

for the Holder at the expense of the Company a new Bond in a principal amount
equal to the unredeemed portion of the Bond surrendered.

SECTION 3.07.   OPTIONAL REDEMPTION.

upon not less than 30 nor more than 60 days' notice, at the redemption prices
(expressed as percentages of principal amount) set forth below plus accrued and

payment of the principal of the Bonds in semiannual installments to the Holders
thereof, the Company shall not be required to make mandatory redemption,
mandatory purchases or sinking fund payments with respect to the Bonds.

SECTION 3.09.   EXTRAORDINARY MANDATORY REDEMPTION.

         (a) The Bonds shall be subject to extraordinary mandatory
redemption by the Company, pro rata, at a redemption price equal to the
outstanding principal amount thereof plus accrued and unpaid interest and any
Registration Default Damages to the date fixed for redemption if (1) (a) an
event occurs which triggers the mandatory redemption or repurchase of any or all
of the Project Securities pursuant to the terms of the Project Indenture and (b)
any funds so required to be applied to such redemption or repurchase remain
after giving effect to such redemption or repurchase of Project Securities, and
such excess funds equal at least $2 million and are distributed to NE LP or NE
LLC or (2) a buyout or similar payment is made to a Partnership under any Power
Purchase Agreement and any such funds are distributed to NE LP or NE LLC in
accordance with the terms of the Project Indenture and terms of the Indenture,
provided that, in each such case, only such funds so distributed must be applied
to the extraordinary mandatory redemption.

         (b) Any redemption pursuant to this Section 3.09 shall be made
pursuant to the provisions of Section 3.01 through 3.06 hereof.

thereof, holds as of 10:00 a.m. Eastern Time on the due date money deposited by
the Company in immediately available funds and designated for and sufficient to
pay all principal, premium, if any, and interest then due. The Company shall pay
all Registration Default Damages, if any, in the same manner on the dates and in

Registrar or co-registrar) where Bonds may be surrendered for registration of
transfer or for exchange and where notices and demands to or upon the Company in
respect of the Bonds and this Indenture may be served. The Company shall give
prompt written notice to the Trustee of the location, and any change in the

fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust
Office of the Trustee.

         The Company may also from time to time designate one or more other
offices or agencies where the Bonds may be presented or surrendered for any or
all such purposes and may from time to time rescind such designations; provided,
however, that no such designation or rescission shall in any manner relieve the
Company of its obligation to appoint the Registrar to maintain an office or
agency in the Borough of Manhattan, the City of New York for such purposes. The
Company shall give prompt written notice to the Trustee of any such designation
or rescission and of any change in the location of any such other office or
agency.

         The Company hereby designates the Corporate Trust Office of the Trustee
as one such office or agency of the Registrar in accordance with Section 2.03.

written statement of the Company's independent public accountants (who shall be
a firm of established international reputation) that in making the examination
necessary for certification of such financial statements, nothing has come to
their attention that would lead them to believe that the Company has violated
any provisions of Article 4 or Article 5 hereof or, if any such violation has
occurred, specifying the nature and period of existence thereof, it being
understood that such accountants shall not be liable directly or indirectly to
any Person for any failure to obtain knowledge of any such violation.

         (c) Each of the Company, NE LP and NE LLC shall, so long as any of
the Bonds are outstanding, deliver to the Trustee, forthwith upon any Officer's

or usury law wherever enacted, now or at any time hereafter in force, that may
affect the covenants or the performance of this Indenture; and the Company, NE
LP and NE LLC each (to the extent that it may lawfully do so) hereby expressly
waives all benefit or advantage of any such law, and covenants that it shall
not, by resort to any such law, hinder, delay or impede the execution of any
power herein granted to the Trustee, but shall suffer and permit the execution
of every such power as though no such law has been enacted.

SECTION 4.07.   RESTRICTED PAYMENTS.

         The Company, NE LP and NE LLC shall make Restricted Payments only from,
and to the extent of, amounts on deposit in the Distribution Account from time
to time. "Restricted Payments" means the direct or indirect: (i) declaration or
payment of any dividend or any other payment or distribution on account of the
Company's, NE LP's or NE LLC's Equity Interests (including, without limitation,
any payment in connection with any merger or consolidation involving the
Company, NE LP or NE LLC) or to the direct or indirect holders of the Company's,
NE LP's or NE LLC's Equity Interests in any capacity (other than dividends or
distributions payable in Equity Interests (other than Disqualified Stock) of the
Company, NE LP or NE LLC or to the Company, NE LP or NE LLC); (ii) repayment of
any Indebtedness owed by NE LP or NE LLC to the Sponsors or their Affiliates,
including, without limitation, any reimbursement obligations with respect to any
letters of credit or guarantees provided by the Sponsors or their Affiliates as
Acceptable Credit Support; (iii) purchase, redemption or other acquisition or
retirement for value (including, without limitation, in connection with any
merger or consolidation involving the Company, NE LP or NE LLC) of any Equity
Interests of the Company, NE LP or NE LLC or any direct or indirect parent of
the Company, NE LP or NE LLC; or (iv) payment on or with respect to, or
purchase, redemption, defeasance or other acquisition or retirement for value of
any Indebtedness that is pari passu with or subordinated to the Bonds (other
than the Bonds), except a scheduled payment of interest or principal.

         The amount of all Restricted Payments (other than cash) shall be the
fair market value on the date of the Restricted Payment of the asset(s) or
securities proposed to be transferred or issued by the Company, NE LP or NE LLC,
pursuant to the Restricted Payment. The fair market value of any non-cash
Restricted Payment shall be determined by the Board of Directors whose
resolution with respect thereto shall be delivered to the Trustee, such
determination to be based upon, and accompanied by, an opinion or appraisal
issued by an accounting, appraisal or investment banking firm of national
standing if such fair market value exceeds $5.0 million. Not later than the date
of making any Restricted Payment, the Company shall deliver to the Trustee an
Officers' Certificate stating that such Restricted Payment is permitted and
setting forth the basis upon which the calculations required by this Section
4.07 were computed, together with a copy of any fairness opinion or appraisal
required by this Indenture.

                                       39


SECTION 4.08.   DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING SUBSIDIARIES.

         The Company, NE LP and NE LLC shall not, and shall not permit any of
its or their Subsidiaries (including NEA and NJEA), directly or indirectly, to
create or otherwise cause or suffer to exist or become effective any encumbrance
or restriction on the ability of any Subsidiary thereof to (i) (a) pay dividends
or make any other distributions to the Company, NE LP and NE LLC or any of its
or their Subsidiaries (1) on its Capital Stock or (2) with respect to any other
interest or participation in, or measured by, its profits, or (b) pay any
indebtedness owed to the Company, NE LP and NE LLC or any of its or their
Subsidiaries, (ii) make loans or advances to the Company, NE LP or NE LLC or any
of its or their Subsidiaries or (iii) transfer any of its properties or assets
to the Company, NE LP or NE LLC or any of its or their Subsidiaries. However,
the foregoing restrictions will not apply to encumbrances or restrictions under
or by reason of (a) the Project Indenture and the other Transaction Documents
(as defined in the Project Indenture as in effect on the date of the Indenture)
and, in each case, as in effect on the date of the Indenture, (b) the Indenture
and the Bonds, (c) applicable law, (d) customary non-assignment provisions in
leases entered into in the ordinary course of business and consistent with past
practices and (e) purchase money obligations for property acquired in the
ordinary course of business that impose restrictions of the nature described in
clause (iii) above on the property so acquired.

SECTION 4.09.   INCURRENCE OF INDEBTEDNESS AND ISSUANCE OF PREFERRED STOCK.

         The Company, NE LP and NE LLC shall not, directly or indirectly,
create, incur, issue, assume, guarantee, otherwise become directly or indirectly
liable, contingently or otherwise, with respect to (collectively, "incur") any
Indebtedness, other than Permitted Indebtedness, and shall not issue any
Disqualified Stock, unless (a) such Indebtedness will be pari passu with or
subordinated to the Note and the Bonds, (b) the proceeds of such incurrence or
issuance are used to make equity contributions to either or both of NEA or NJEA,
(c) the proceeds of such incurrence or issuance are used to finance the
completion of Required Improvements or capital expenditures for the Projects
other than Required Improvements, (d) if the proceeds of such Indebtedness are
used to finance the completion of Required Improvements (as defined in the
Project Indenture as in effect on the date of the Indenture), (i) the Projected
Debt Service Coverage Ratio (determined on a pro forma basis giving effect to
the incurrence and the application of the net proceeds therefrom and the
construction of the Required Improvements) measured on each remaining
semi-annual payment date in respect of the Bonds is at least 1.2 to 1 and (ii)
an independent engineer acceptable to the Trustee (which may, absent any
conflict or the objection of the Trustee, be the Independent Engineer with
respect to the Project Securities) certifies that the Improvements are Required
Improvements (as defined in the Project Indenture as in effect on the date of
the Indenture) and that there will be sufficient funds available to construct
the Required Improvements after the incurrence and (e) if the proceeds of such
Indebtedness are used to finance capital expenditures for the Projects other
than Required Improvements, (i) the Projected Debt Service Coverage Ratio

                                       40


(determined on a pro forma basis giving effect to the incurrence and the
application of the net proceeds therefrom and the proposed capital expenditures)
measured on each remaining semi-annual payment date of the Bonds is at least 2
to 1 and the average of such Projected Debt Service Coverage Ratios is at least
3 to 1 and (ii) Moody's and S&P confirm that the then current ratings of the
Bonds will not be lowered as a result of such incurrence. "Permitted
Indebtedness" means subordinated loans or reimbursement obligations owing to a
Sponsor or any Affiliate thereof (i) which can only be repaid to the extent
Restricted Payments can be made, (ii) in respect of which remedies cannot be
exercised by such Sponsor or Affiliate so long as the Bonds are outstanding,
(iii) incurred at a time when the minimum Projected Debt Service Coverage Ratio
(assuming, for purposes of such calculation, that scheduled debt service
payments in respect of Permitted Indebtedness that is subordinate in right of
payment to the Bonds, the Note and the Bond Guaranty is included in clause (ii)
of the definition of "Projected Debt Service Coverage Ratio") on each
semi-annual payment date of the Bonds is at least 1.5 to 1 (provided that the
incurrence of reimbursement obligations subordinated to the Bonds of NE LP to
the issuers of Acceptable Credit Support under the Indenture and in respect of
Guarantees issued by FPL Group Capital and/or Backup Letters of Credit and
Substitute Letters of Credit (as defined in the Project Indenture) pursuant to
the Project Indenture shall not be subject to such Projected Debt Service
Coverage Ratio test) or Moody's and S&P confirm that the then current ratings of
the Bonds will not be lowered as a result of such incurrence and (iv) the
proceeds of which are used to make equity contributions to either NEA or NJEA.

         For purposes of determining compliance with this Section 4.09, in the
event that an item of Indebtedness meets the criteria of more than one of the
categories of Permitted Indebtedness described in clauses (i) through (iv) above
or is entitled to be incurred pursuant to the first paragraph of this Section
4.09, the Company, NE LP and NE LLC shall each, in its sole discretion, classify
such item of Indebtedness in any manner that complies with this Section 4.09.
Accrual of interest shall not be deemed to be an incurrence of Indebtedness for
purposes of this Section 4.09.

SECTION 4.10.   LIMITATIONS ON PROJECT INDEBTEDNESS

         Notwithstanding the terms of the Project Indenture, NE LP and NE LLC
shall not permit ESI Tractebel Funding Corp. or the Partnerships to create,
issue, incur, assume, guarantee, otherwise become liable for or suffer to exist
any Debt (as defined in the Project Indenture as in effect on the date of the
Indenture) to finance the construction of Required Improvements unless, after
giving effect to the incurrence of such Debt and the application of the proceeds
thereof, the Projected Debt Service Coverage Ratio for the 12-month period
beginning on the date of such incurrence and for each succeeding 12-month period
thereafter through the final maturity of the Bonds is at least 1.2 to 1.

         In addition, notwithstanding the terms of the Project Indenture, NE LP
and NE LLC shall not permit ESI Tractebel Funding Corp. or the Partnerships to
create, issue, incur, assume, guarantee, otherwise become liable for or suffer
to exist any Debt (as defined in the Project Indenture as in effect on the date
of the Indenture), other than Debt to finance the construction of Required
Improvements, unless after giving effect to the incurrence of such Debt and the
application of the proceeds thereof, (i) the Projected Debt Service Coverage

                                       41


Ratio measured on each remaining semi-annual payment date of the Bonds is at
least 2 to 1 and (ii) the average of such Projected Debt Service Coverage Ratios
is at least 3 to 1.

         Finally, NE LP and NE LLC shall not permit ESI Tractebel Funding Corp.
or the Partnerships to create, incur, assume, guarantee, otherwise become liable
for or suffer to exist any Indebtedness, Guarantees or indemnity obligations
following the repayment, prepayment or defeasance of all of the Project
Securities or the termination or expiration of the Project Indenture, other than
in accordance with one of the two preceding paragraphs.

SECTION 4.11. TRANSACTIONS WITH AFFILIATES.

         The Company, NE LP and NE LLC shall not make any payment to, or sell,
lease, transfer or otherwise dispose of any of its properties or assets to, or
purchase any property or assets from, or enter into or make or amend any
transaction, contract, agreement, understanding, loan, advance or Guarantee
with, or for the benefit of, any Affiliate thereof (each of the foregoing, an
"Affiliate Transaction"), unless such Affiliate Transaction is on terms that are
no less favorable to the Company, NE LP or NE LLC (as the case may be) than
those that would have been obtained in a comparable transaction by the Company,
NE LP or NE LLC with an unrelated Person. Notwithstanding the foregoing, the
following shall not be deemed to be Affiliate Transactions: (i) transactions
between or among the Company, NE LP, NE LLC or any of their Affiliates
contemplated by any agreement entered into prior to the date of the Indenture;
(ii) payments of reasonable directors' fees to Persons who are not otherwise
Affiliates of the Company, NE LP or NE LLC; and (iii) Restricted Payments that
are permitted under Section 4.07 hereof.

SECTION 4.12. LIENS.

         The Company, NE LP and NE LLC shall not, directly or indirectly create,
incur, assume or otherwise cause or suffer to exist or become effective any Lien
on any of their assets or properties now owned or hereafter acquired, or any
income or profits therefrom, or assign or convey any right to receive income
therefrom, except for Permitted Liens.

SECTION 4.13. BUSINESS ACTIVITIES.

         (a) The Company shall not engage in any business other than the
issuance of the Bonds and the incurrence of the other Indebtedness permitted by
the Indenture to be incurred by the Company and (b) NE LP and NE LLC shall not
engage in any business other than holding, directly or indirectly, the partner
interests of NEA and NJEA, and, with respect to NE LP, acting as general partner
of NEA and NJEA, and the issuance of the Note and the Bond Guaranty and the
incurrence of the other Indebtedness permitted by the Indenture to be incurred
by NE LP and NE LLC.

                                       42


SECTION 4.14.   CORPORATE EXISTENCE.

         Subject to Article 5 hereof, the Company, NE LP and NE LLC shall each
do or cause to be done all things necessary to preserve and keep in full force
and effect (i) its corporate or partnership existence, and the corporate,
partnership or other existence of each of its Subsidiaries, in accordance with
the respective organizational documents (as the same may be amended from time to
time) of the Company, NE LP and NE LLC or any such Subsidiary and (ii) the
rights (charter and statutory), licenses and franchises of the Company and their
Subsidiaries; provided, however, that the Company, NE LP and NE LLC shall not be
required to preserve any such right, license or franchise, or the corporate,
partnership or other existence of any of its Subsidiaries, if the Board of
Directors shall determine that the preservation thereof is no longer desirable
in the conduct of the business of the Company, NE LP and NE LLC and their
respective Subsidiaries, taken as a whole, and that the loss thereof is not
adverse in any material respect to the Holders of the Bonds.

SECTION 4.15.   OFFER TO REPURCHASE UPON CHANGE OF CONTROL.

         (a) Upon the occurrence of a Change of Control (which shall not
occur if Moody's and S&P confirm that the then existing ratings of the Bonds
will not be lowered as a result of any of the events that, in the absence of
such confirmed rating, would constitute a Change of Control), the Company shall
offer to each Holder to repurchase all or any part (equal to $100,000 or an
integral multiple of $1,000 in excess thereof) of such Holder's Bonds pursuant
to the offer described below (the "Change of Control Offer") at a purchase price
in cash equal to 101% of the aggregate principal amount thereof plus accrued and
unpaid interest and Registration Default Damages thereon, if any, to the date of
purchase (the "Change of Control Payment"). Within ten days following any Change
of Control, the Company shall mail a notice to each Holder describing the
transaction or transactions that constitute the Change of Control and offering
to repurchase Bonds on the date specified in such notice, which date shall be no
earlier than 30 days and no later than 60 days from the date such notice is
mailed (the "Change of Control Payment Date"), pursuant to the procedures
required by the Indenture and described in such notice. The Company shall comply
with the requirements of Rule 14e-1 under the Exchange Act and any other
securities laws and regulations thereunder to the extent such laws and
regulations are applicable in connection with the repurchase of the Bonds as a
result of a Change of Control.

         (b) On the Change of Control Payment Date, the Company shall, to
the extent lawful, (1) accept for payment all Bonds or portions thereof properly
tendered pursuant to the Change of Control Offer, (2) deposit with the Paying
Agent an amount equal to the Change of Control Payment in respect of all Bonds
or portions thereof so tendered and (3) deliver or cause to be delivered to the
Trustee the Bonds so accepted together with an Officer's Certificate stating the
aggregate principal amount of Bonds or portions thereof purchased by the
Company. The Paying Agent shall promptly pay to each Holder that has so tendered
Bonds the Change of Control Payment for such Bonds, and the Trustee shall
promptly authenticate and mail (or cause to be transferred by book entry) to
each Holder a new Bond equal in principal amount to any unpurchased portion of
the Bonds surrendered, if any; provided that each such new Bond shall be in a

                                       43


principal amount of $100,000 or an integral multiple of $1,000 in excess
thereof. The Company shall announce publicly the results of the Change of
Control Offer on or as soon as practicable after the Change of Control Payment
Date.

          (c) Notwithstanding anything to the contrary in this Section 4.15,
the Company shall not be required to make a Change of Control Offer upon a
Change of Control if a third party makes the Change of Control Offer in the
manner, at the times and otherwise in compliance with the requirements set forth
in this Section 4.15 hereof, and purchases all Bonds validly tendered and not
withdrawn under such Change of Control Offer.

         "Change of Control" means the occurrence of any of the following: (i)
the sale, lease, transfer, conveyance or other disposition (other than by way of
merger or consolidation), in one or a series of related transactions, of all or
substantially all of the assets of NE LP, NE LLC, NEA or NJEA to any "person" or
"group" (as each such term is used in Section 13(d)(3) and 14(d)(2) of the
Exchange Act) other than the Sponsors or their Related Parties; (ii) the
adoption of a plan relating to the liquidation or dissolution of NE LP, NE LLC,
NEA or NJEA (other than as permitted by the Indenture); (iii) the consummation
of any transaction or series of related transactions (including, without
limitation, any merger or consolidation) the result of which is that any person
or group (as defined above), other than the Sponsors and their Related Parties,
becomes the "beneficial owner" (as such term is defined in Rule 13d-3 and Rule
13d-5 under the Exchange Act, except that a person or group shall be deemed to
have "beneficial ownership" of all securities that such person or group has the
right to acquire, whether such right is currently exercisable or is exercisable
only upon the occurrence of a subsequent condition), directly or indirectly, of
more than 50% of the voting power of any general partner of NE LP, NEA or NJEA
or of the voting power of the managing member of NE LLC by way of merger or
consolidation or otherwise other than a transaction involving an acquisition of
FPL Group or Tractebel S.A., (iv) the consummation of any transaction or series
of related transactions the result of which is that any person or group (as
defined above) owns, directly or indirectly, more of the economic and voting
interest of the Sponsors, NE LP, NE LLC, NEA or NJEA or of the voting power of
the managing member of NE LLC than do FPL Group and Tractebel S.A.; or (v) the
consummation of any transaction or series of related transactions the result of
which is that any person or group (as defined above) other than the Sponsors and
the Related Parties owns, directly or indirectly, more of the voting power of
any general partner of NE LP, NEA or NJEA than do the Sponsors and their Related
Parties; provided that, notwithstanding the foregoing, a Change of Control shall
not occur if Moody's and S&P confirm that the then existing ratings of the Bonds
will not be lowered as a result of any of the foregoing events.

         If any of the events described in clauses (i) through (v) of the
definition of "Change of Control" occurs, but the Company is not required to
offer to purchase the Bonds because Moody's and S&P confirm that the then
existing rating of the Bonds will not be lowered as a result of such event, then
immediately after such event, the definitions of "Sponsor" and "Related Parties"
set forth above shall be amended by supplemental indenture (without the consent
of the Holders of the Bonds) to mean the entity or entities that Moody's and S&P
relied upon, if any, in confirming the then existing ratings of the Bonds.

                                       44


SECTION 4.16.  NO SENIOR SUBORDINATED DEBT.

         Notwithstanding the provisions of Section 4.09 hereof, none of the
Company, NE LP or NE LLC shall, nor shall any such party permit any of its
Subsidiaries or Affiliates to, create, issue, incur, assume, guarantee,
otherwise become liable for or suffer to exist any Indebtedness that is
subordinated or junior in right of payment to the Project Indebtedness and
senior in any respect in right of payment to the Bonds, the Note or the Bond
Guaranty (other than Indebtedness expressly permitted to be incurred by the
Project Indenture and the Indenture).

SECTION 4.17.  AMENDMENTS TO, AND ASSIGNMENTS OF, PROJECT DOCUMENTS.

         The Company, NE LP and NE LLC shall not permit or suffer NEA or NJEA
(a) to waive a right under, or modify, terminate or amend, any material
governmental consent, any material term of any Project Document (as defined in
the Project Indenture as in effect on the date of the Indenture), other than any
Power Purchase Agreement, or any material term of the Project Indenture unless
such waiver, modification, termination or amendment could not reasonably be
expected to have a material adverse effect on the Company, NE LP, NE LLC or the
Holders of the Bonds or (b) to assign any of its rights under any of the Project
Documents (as defined in the Project Indenture as in effect on the date of the
Indenture) other than as permitted by the Indenture or the Project Indenture.
The Company, NE LP and NE LLC shall not permit or suffer NEA or NJEA to waive a
right under, or modify, terminate or amend, any material term of any Power
Purchase Agreement unless (i) NE LP delivers to the Trustee a certificate, in
form and substance reasonably satisfactory to the Trustee, of an independent
engineer acceptable to the Trustee (which may, absent any conflict or the
objection of the Trustee, be the Independent Engineer with respect to the
Project Securities), certifying that such waiver, modification, termination or
amendment could not reasonably be expected to have a material adverse effect on
the Company, NE LP, NE LLC or the Holders of the Bonds and (ii) Moody's and S&P
confirm that the then existing ratings of the Bonds will not be lowered as a
result of such waiver, modification, termination or amendment.

SECTION 4.18.  COMPLIANCE.

         Each of the Company, NE LP and NE LLC shall at all times obtain,
maintain and comply in all material respects with all material governmental
consents and all applicable laws. NE LP shall at all times, in its capacity as
general partner of NEA and NJEA, cause NEA and NJEA to comply with all material
terms and provisions of the Project Indenture (as in effect as of the date of
the Indenture), unless the failure to comply could not reasonably be expected to
have a material adverse effect on the Company, NE LP, NE LLC or the Holders of
the Bonds. Notwithstanding the expiration or termination of the Project
Indenture (whether at the stated maturity of the last to mature of the Project
Securities or otherwise) or the exercise by holders of the Project Securities of
their rights with respect to satisfaction and discharge of the Project
Indenture, legal or covenant defeasance or any other prepayment of the Project

                                       45


Securities permitted or required by the Project Indenture, NE LP shall, in its
capacity as general partner of NEA and NJEA, cause NEA and NJEA to comply with
the covenants and provisions contained in Sections 7.2, 7.3, 7.4, 7.5, 7.12,
7.13, 7.14, 7.16, 7.20, 7.21 and 7.25 of the Project Indenture, as if such
covenants and provisions were still in full force and effect (which covenants
and provisions relate to such matters as the maintenance of existence of the
Partnerships, the maintenance of rights necessary to conduct the business of the
Partnerships, the operation and maintenance of the Projects, compliance with the
formation documents of the Partnerships, the maintenance of governmental
approvals, compliance with laws, the maintenance of insurance, the payment of
taxes, the incurrence of liens and guaranties, the prohibition on certain
dispositions of assets, the nature of business conducted by the partnerships,
employee benefit plans, certain transactions with affiliates, the making of
investments and the maintenance of QF status by the Partnerships.)

SECTION 4.19.  MAINTAINING RIGHTS UNDER PROJECT DOCUMENTS.

         Subject to Sections 4.17 and 4.18 hereof, the Company, NE LP and NE LLC
shall take all actions necessary to cause NEA and NJEA to maintain and preserve
the material rights granted to NEA and NJEA pursuant to the Project Documents
and to comply therewith unless the failure to maintain and preserve such rights
could not reasonably be expected to have a material adverse effect on the
Company, NE LP, NE LLC or the Holders of the Bonds.

SECTION 4.20.  PARTNERSHIP DISTRIBUTIONS.

         NE LP shall, in its capacity as general partner of NEA and NJEA, cause
NEA and NJEA to distribute to NE LP and NE LLC all amounts released to NEA and
NJEA or permitted to be withdrawn by NEA or NJEA from the Partnership
Distribution Fund (as defined in the Project Indenture as in effect on the date
of the Indenture) or any subfund thereof in accordance with the Project
Indenture, and; following the expiration or termination of the Project
Indenture, shall in its capacity as general partner of NEA and NJEA, cause NEA
and NJEA to distribute to NE LP and NE LLC all amounts available for
distribution in accordance with the Project Indenture.

SECTION 4.21.  LIMITATION ON ISSUANCES OF GUARANTEES AND INDEMNITIES.

         The Company, NE LP and NE LLC shall not directly or indirectly, incur
or have outstanding any Guarantees or indemnities or assume any other suretyship
obligations, except, (a) the Bond Guaranty, (b) Guarantees arising in the
ordinary course of business not to exceed $250,000 in the aggregate at any one
time outstanding and (c) indemnities or reimbursement obligations with respect
to any Acceptable Credit Support or otherwise, so long as such indemnities or
reimbursement obligations are payable only to the extent Restricted Payments can
be made and the party in respect of whom such indemnities or reimbursement
obligations run in favor waives its rights to exercise remedies in respect
thereof so long as the Bonds are outstanding.

                                       46


SECTION 4.22.  LIMITATIONS ON LOANS AND ADVANCES.

cause to be paid any consideration, whether by way of interest, fee or
otherwise, to any Holder of any Bonds for or as an inducement to any consent,
waiver or amendment of any of the terms or provisions of the Indenture or the
Bonds unless such consideration is offered to be paid or is paid to all Holders
of the Bonds that consent, waive or agree to amend in the time frame set forth
in the solicitation documents relating to such consent, waiver or agreement.

SECTION 4.24.  ADDITIONAL BOND GUARANTEES.

         If the Company, NE LP, NE LLC or any of their respective Subsidiaries
shall acquire or create another Subsidiary after the date of this Indenture,

executing a Supplemental Indenture in the form attached hereto as Exhibit F and
deliver an Opinion of Counsel to the Trustee to the effect that such
Supplemental Indenture has been duly authorized, executed and delivered by such
Subsidiary and constitutes a valid and binding obligation of such Subsidiary,
enforceable against such Subsidiary in accordance with its terms (subject to
customary exceptions).

SECTION 4.25.  REGULATORY LIMITATIONS.

         Neither the Company nor NE LP shall, nor shall NE LP permit either
Partnership to, take or omit to take any action, or permit any person to take or

sales without jeopardizing either Project's Exempt Wholesale Generator status;
provided that any failure to maintain Exempt Wholesale Generator status presents

successor entity formed by such consolidation or into or with which the Company,
NE LP or NE LLC is merged or to which such sale, assignment, transfer, lease,
conveyance or other disposition is made shall succeed to, and be substituted for

or other disposition, the provisions of this Indenture referring to the
"Company," "NE LP" or "NE LLC", as the case may be, shall refer instead to the
successor entity and not to the Company, NE LP or NE LLC, as the case may be,
and may exercise every right and power of the Company, NE LP or NE LLC, as the
case may be, under this Indenture with the same effect as if such successor
Person had been named as the Company, NE LP or NE LLC, as the case may be,
herein; provided, however, that the predecessor Company shall not be relieved
from the obligation to pay the principal of and interest on the Bonds except in
the case of a sale of all of the Company's assets that meets the requirements of
Section 5.01 hereof.

          (e) the Company, NE LP or NE LLC defaults in the payment when due

          (f) a final judgment or final judgments for the payment of money
are entered by a court or courts of competent jurisdiction against the Company,
NE LP or NE LLC and such judgment or judgments remain unpaid or undischarged for
a period (during which execution shall not be effectively stayed) of 60 days,
provided that the aggregate of all such undischarged judgments exceeds $3
million;

          (g) Any of the material provisions of the Collateral Documents
shall be held in any judicial proceeding to be unenforceable or invalid or shall
cease for any reason to be in full force and effect or any lien granted thereby
or the priority thereof ceases or fails for any reason to be in full force and
effect (and such unenforceable provisions or cessation or failure of a lien is
not cured within 10 days after the Company, NE LP or NE LLC has obtained
knowledge thereof);

          (h) the Company, NE LP or NE LLC pursuant to or within the meaning
of Bankruptcy Law:

                  (i)  commences a voluntary case,

                  (ii) consents to the entry of an order for relief against it
         in an involuntary case,

                (i) is for relief against the Company, NE LP or NE LLC in an
        involuntary case;

                                       50

and in full force and effect in all material respects;

          (k) Any default by a counterparty under any of the Material
Project Agreements occurs (as defined in the Project Indenture as in effect on
the date of the Indenture) that would likely have a material adverse effect on
the Company, NE LP or NE LLC or the Holders of the Bonds and such default is not
cured within 180 days (or 360 days if the applicable Partnership has promptly
commenced and is diligently using its best efforts to cure such default);

          (l) An "Event of Default" (as defined in the Project Indenture as
in effect on the date of the Indenture) occurs other than as a result of the
breach of an immaterial covenant; and

          (m) the maturity date of the Project Securities are accelerated.

SECTION 6.02. ACCELERATION.

         If any Event of Default (other than an Event of Default specified in
clause (h) or (i) of Section 6.01 hereof with respect to the Company NE LP or NE
LLC), occurs and is continuing, the Trustee or the Holders of at least 25% in
aggregate principal amount of the then outstanding Bonds may declare by written
notice to the Company the principal amount of all the Bonds then outstanding to
be due and payable immediately. Upon any such declaration, the Bonds shall
become due and payable immediately. Notwithstanding the foregoing, if an Event
of Default specified in clause (h) or (i) of Section 6.01 hereof occurs with
respect to the Company, NE LP or NE LLC, the principal amount of all outstanding
Bonds shall be due and payable immediately without further action or notice. The
Holders of the Bonds may not enforce the Indenture or the Bonds except as
provided in the Indenture. Subject to Section 6.05 and 7.02(f), Holders of a
majority in principal amount of the then outstanding Bonds may direct the
Trustee in its exercise of any trust or power. The Holders of not less than a
majority in aggregate principal amount of the then outstanding Bonds by written
notice to the Trustee may on behalf of all of the Holders rescind an
acceleration and its consequences under the Indenture if the recission would not
conflict with any judgment or decree and if all existing Events of Default
(except a continuing Default or Event of Default in the payment of principal,
interest or premium, if any, on the Bonds that has become due solely because of
the acceleration) have been cured or waived.

         If an Event of Default occurs on or after June 30, 2008 by reason of
any willful action (or inaction) taken (or not taken) by or on behalf of the
Company with the intention of avoiding payment of the premium that the Company

                                       51


would have had to pay if the Company then had elected to redeem the Bonds
pursuant to Section 3.07 hereof, then, upon acceleration of the Bonds, an
equivalent premium shall also become and be immediately due and payable, to the
extent permitted by law, anything in this Indenture or in the Bonds to the
contrary notwithstanding. If an Event of Default occurs prior to June 30, 2008
by reason of any willful action (or inaction) taken (or not taken) by or on
behalf of the Company with the intention of avoiding the prohibition on optional
redemption of the Bonds prior to such date, then, upon acceleration of the
Bonds, the Make Whole Premium shall also become and be immediately due and
payable to the extent permitted by law.

SECTION 6.03.  OTHER REMEDIES.

         If an Event of Default occurs and is continuing, the Trustee may pursue
any available remedy to collect the payment of principal, premium, if any, and
interest on the Bonds, the Note and the Bond Guaranty or to enforce the
performance of any provision of the Bonds or this Indenture.

         The Trustee may maintain a proceeding even if it does not possess any
of the Bonds or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Holder of a Bond in exercising any right or
remedy accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. All remedies are
cumulative to the extent permitted by law.

SECTION 6.04.  WAIVER OF PAST DEFAULTS.

         Holders of not less than a majority in aggregate principal amount of
the then outstanding Bonds by written notice to the Trustee may on behalf of all
of the Holders waive an existing Default or Event of Default and its
consequences under the Indenture, except a continuing Default or Event of
Default in the payment of the principal of, premium and Registration Default
Damages, if any, or interest on, the Bonds (including in connection with an
offer to purchase); provided, however, that the Holders of not less than a
majority in aggregate principal amount of the then outstanding Bonds by written
notice to the Trustee may on behalf of all of the Holders rescind an
acceleration and its consequences under the Indenture, including any related
payment default that resulted from such acceleration. Upon any such waiver, such
Default shall cease to exist, and any Event of Default arising therefrom shall
be deemed to have been cured for every purpose of this Indenture; but no such
waiver shall extend to any subsequent or other Default or impair any right
consequent thereon or affect any rights of the Trustee to collect amounts due to
it pursuant to Section 7.07 hereof.

SECTION 6.05.  CONTROL BY MAJORITY.

         Holders of a majority in aggregate principal amount of the then
outstanding Bonds may direct the time, method and place of conducting any
proceeding for exercising any remedy available to the Trustee or exercising any
trust or power conferred on it. However, the Trustee may refuse to follow any
direction that conflicts with law or this Indenture or that the Trustee

                                       52


determines may be unduly prejudicial to the rights of other Holders of Bonds or
that may involve the Trustee in personal liability.

SECTION 6.06.  LIMITATION ON SUITS.

         A Holder of a Bond may pursue a remedy with respect to this Indenture
or the Bonds only if:

         (a) the Holder of a Bond gives to the Trustee written notice of a
continuing Event of Default;

         (b) the Holders of at least 25% in principal amount of the then
outstanding Bonds make a written request to the Trustee to pursue the remedy;

         (c) such Holder of a Bond or Holders of Bonds offer and, if requested,
provide to the Trustee indemnity satisfactory to the Trustee against any loss,
liability or expense;

         (d) the Trustee does not comply with the request within 60 days after
receipt of the request and the offer and, if requested, the provision of
indemnity; and

         (e) during such 60-day period the Holders of a majority in principal
amount of the then outstanding Bonds do not give the Trustee a direction
inconsistent with the request.

         A Holder of a Bond may not use this Indenture to prejudice the rights
of another Holder of a Bond or to obtain a preference or priority over another
Holder of a Bond.

SECTION 6.07.  RIGHTS OF HOLDERS OF BONDS TO RECEIVE PAYMENT.

         Notwithstanding any other provision of this Indenture, the right of any
Holder of a Bond to receive payment of principal, premium and Registration
Default Damages, if any, and interest on the Bond, on or after the respective
due dates expressed in the Bond (including in connection with an offer to
purchase), or to bring suit for the enforcement of any such payment on or after
such respective dates, shall not be impaired or affected without the consent of
such Holder.

SECTION 6.08.  COLLECTION SUIT BY TRUSTEE.

         If an Event of Default specified in Section 6.01(a) or (b) occurs and
is continuing, the Trustee is authorized to recover judgment in its own name and
as trustee of an express trust against the Company for the whole amount of
principal of, premium and Registration Default Damages, if any, and interest
remaining unpaid on the Bonds and the Note and interest on overdue principal
and, to the extent lawful, interest and such further amount as shall be
sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel.

                                       53


SECTION 6.09.  TRUSTEE MAY FILE PROOFS OF CLAIM.

         The Trustee is authorized to file such proofs of claim and other papers
or documents and take such other actions as it may deem necessary or advisable
to have the claims of the Trustee (including any claim for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel) and the Holders of the Bonds allowed in any judicial proceedings
relative to the Company, NE LP or NE LLC (or any other obligor upon the Bonds),
its creditors or its property and shall be entitled and empowered to collect,
receive and distribute any money or other property payable or deliverable on any
such claims, and any custodian in any such judicial proceeding is hereby
authorized by each Holder to make such payments to the Trustee, and in the event
that the Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To
the extent that the payment of any such compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel, and any other amounts due
the Trustee under Section 7.07 hereof out of the estate in any such proceeding,
shall be denied for any reason, payment of the same shall be secured by a Lien
on, and shall be paid out of, any and all distributions, dividends, money,
securities and other properties that the Holders may be entitled to receive in
such proceeding whether in liquidation or under any plan of reorganization or
arrangement or otherwise. Nothing herein contained shall be deemed to authorize
the Trustee to authorize or consent to or accept or adopt on behalf of any
Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Bonds or the rights of any Holder, or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding.

SECTION 6.10.  PRIORITIES.

         If the Trustee collects any money pursuant to this Article, it shall
pay out the money in the following order:

         First: to the Trustee, its agents and attorneys for amounts due under
Section 7.07 hereof, including payment of all compensation, expense and
liabilities incurred, and all advances made, by the Trustee and the costs and
expenses of collection;

         Second: to Holders of Bonds for amounts due and unpaid on the Bonds for
principal, premium and Registration Default Damages, if any, and interest,
ratably (based on the principal amount of Bonds deemed hereunder to be
outstanding at the time of distribution), without preference or priority of any
kind, according to the amounts due and payable on the Bonds for principal,
premium and Registration Default Damages, if any and interest, respectively;

         Third: to the ratable payment of all other Obligations under this
Indenture, until all Obligations shall have been paid in full; and

         Fourth: to or at the direction of NE LP or to such party as a court of
competent jurisdiction shall direct.

                                       54

         The Trustee may fix a record date and payment date for any payment to
Holders of Bonds pursuant to this Section 6.10.

SECTION 6.11.  UNDERTAKING FOR COSTS.

         In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as a Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in the suit, having due regard to
the merits and good faith of the claims or defenses made by the party litigant.
This Section does not apply to a suit by the Trustee, a suit by a Holder of a
Bond pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in
principal amount of the then outstanding Bonds.

                                   ARTICLE 7.
                                     TRUSTEE

SECTION 7.01.  DUTIES OF TRUSTEE.

          (a) If an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in its exercise, as a
prudent man would exercise or use under the circumstances in the conduct of his
own affairs provided that the Trustee shall be entitled to presume conclusively
that no premium or Make Whole Premium is due pursuant to the last paragraph of
Section 6.02 unless it receives evidence which in its reasonable opinion, it
believes establishes that such additional amount is due.

          (b) Except during the continuance of an Event of Default:

                  (i) the duties of the Trustee shall be determined solely by
         the express provisions of this Indenture and the Trustee need perform
         only those duties that are specifically set forth in this Indenture and
         no others, and no implied covenants or obligations shall be read into
         this Indenture against the Trustee; and

                  (ii) in the absence of bad faith on its part, the Trustee may
         conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and conforming to the requirements of
         this Indenture. However, the Trustee shall examine the certificates and
         opinions to determine whether or not they conform to the requirements
         of this Indenture.

          (c) The Trustee may not be relieved from liabilities for its own
negligent action, its own negligent failure to act, or its own willful
misconduct, except that:

                  (i) this paragraph does not limit the effect of paragraph (b)
         of this Section;

                                       55


                  (ii) the Trustee shall not be liable for any error of judgment
         made in good faith by a Responsible Officer, unless it is proved that
         the Trustee was negligent in ascertaining the pertinent facts; and

                  (iii) the Trustee shall not be liable with respect to any
         action it takes or omits to take in good faith in accordance with a
         direction received by it pursuant to Section 6.05 hereof.

provided that the Trustee shall not be deemed to know of any Default or any fact
or occurrence upon the happening of which it might be required to take action
unless one of its Responsible Officers has actual knowledge thereof or it has
received written notice thereof.

          (d) Whether or not therein expressly so provided, every provision
of this Indenture that in any way relates to the Trustee is subject to
paragraphs (a), (b), and (c) of this Section.

          (e) No provision of this Indenture shall require the Trustee to
expend or risk its own funds or incur any liability. The Trustee shall be under
no obligation to exercise any of its rights and powers under this Indenture at
the request of any Holders, unless such Holder shall have offered to the Trustee
security and indemnity satisfactory to it against any loss, liability or
expense.

          (f) The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with the Company.
Money held in trust by the Trustee need not be segregated from other funds
except to the extent required by law.

SECTION 7.02.  RIGHTS OF TRUSTEE.

          (a) The Trustee may conclusively rely upon any document believed
by it to be genuine and to have been signed or presented by the proper Person.
The Trustee need not investigate any fact or matter stated in the document.

          (b) Before the Trustee acts or refrains from acting, it may
require an Officers' Certificate or an Opinion of Counsel or both or a
certificate or opinion of an independent engineer recognized as an expert in its
field or of internationally recognized independent accountant. The Trustee shall
not be liable for any action it takes or omits to take in good faith in reliance
on such Officers' Certificate or Opinion of Counsel or such certificate or
opinion of an independent engineer or of independent accountant. With respect to
the amount of Registration Default Damages owed at any time, the Trustee may
rely upon written notification from the Purchaser. The Trustee may consult with
counsel and the written advice of such counsel or any Opinion of Counsel shall
be full and complete authorization and protection from liability in respect of
any action taken, suffered or omitted by it thereunder in good faith and in
reliance thereon.

          (c) The Trustee may act through its attorneys and agents and shall not
be responsible for the misconduct or negligence of any agent appointed with due
care.

                                       56


          (d) The Trustee shall not be liable for any action it takes or omits
to take in good faith that it believes to be authorized or within the rights or
powers conferred upon it by this Indenture.

          (e) Unless otherwise specifically provided in this Indenture, any
demand, request, direction or notice from the Company shall be sufficient if
signed by an Officer of the Company.

          (f) The Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by this Indenture at the request or direction of
any of the Holders unless such Holders shall have offered to the Trustee
reasonable security or indemnity against the costs, expenses and liabilities
that might be incurred by it in compliance with such request or direction.

          (g) The Trustee shall not be bound to make any investigation into the
facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, direction, consent, order, bond, debenture,
note, other evidence of indebtedness or other paper or document, but the
Trustee, in its discretion, may make such further inquiry or investigation into
such facts or matters as it may see fit, and, if the Trustee shall determine to
make such further inquiry or investigation, it shall be entitled to examine the
books, records and premises of the Company, personally or by agent or attorney;

          (h) any permissive right or power available to the Trustee under this
Indenture or any supplement hereto shall not be construed to be a mandatory duty
or obligation;

          (i) the Trustee shall have no liability for any inaccuracy in the
books or records of, or for any actions or omissions of, DTC, Euroclear or CEDEL
or any other Depository or Participant.

SECTION 7.03.  INDIVIDUAL RIGHTS OF TRUSTEE.

         The Trustee in its individual or any other capacity may become the
owner or pledge of Bonds and may otherwise deal with the Company or any
Affiliate of the Company with the same rights it would have if it were not
Trustee. However, in the event that, after the occurrence of an Event of
Default, the Trustee has or acquires any conflicting interest as determined in
Section 310(b) of the TIA it must eliminate such conflict within 90 days, apply
to the SEC for permission to continue as trustee or resign. Any Agent may do the
same with like rights and duties. The Trustee is also subject to Sections 7.10
and 7.11 hereof.

SECTION 7.04.  TRUSTEE'S DISCLAIMER.

         The Trustee shall not be responsible for and makes no representation as
to the validity or adequacy of this Indenture or the Bonds, it shall not be
accountable for the Company's use of the proceeds from the Bonds or any money
paid to the Company or upon the Company's direction under any provision of this
Indenture, it shall not be responsible for the use or application of any money
received by any Paying Agent other than the Trustee, and it shall not be
responsible for any statement or recital herein or any statement in the Bonds or

                                       57


any other document in connection with the sale of the Bonds or pursuant to this
Indenture other than its certificate of authentication.

SECTION 7.05.  NOTICE OF DEFAULTS.

         If a Default or Event of Default occurs and is continuing and if it is
known to the Trustee, the Trustee shall mail to Holders of Bonds a notice of the
Default or Event of Default within 90 days after it occurs. Except in the case
of a Default or Event of Default in payment of principal of, premium, if any, or
interest on any Bond, the Trustee may withhold the notice if and so long as a
committee of its Responsible Officers in good faith determines that withholding
the notice is in the interests of the Holders of the Bonds.

SECTION 7.06.  REPORTS BY TRUSTEE TO HOLDERS OF THE BONDS.

         Within 60 days after each May 15 beginning with the May 15 following
the date of this Indenture, and for so long as Bonds remain outstanding, the
Trustee shall mail to the Holders of the Bonds a brief report dated as of such
reporting date that complies with TIA ss. 313(a) (but if no event described in
TIA ss. 313(a) has occurred within the twelve months preceding the reporting
date, no report need be transmitted). The Trustee also shall comply with TIA ss.
313(b)(2). The Trustee shall also transmit by mail all reports as required by
TIA ss. 313(c).

         A copy of each report at the time of its mailing to the Holders of
Bonds shall be mailed to the Company and filed with the SEC and each stock
exchange on which the Bonds are listed in accordance with TIA ss. 313(d). The
Company shall promptly notify the Trustee when the Bonds are listed on any stock
exchange.

SECTION 7.07.  COMPENSATION AND INDEMNITY.

         The Company shall pay to the Trustee from time to time reasonable
compensation for its acceptance of this Indenture and services hereunder. The
Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust. The Company shall reimburse the Trustee promptly
upon request for all reasonable disbursements, advances and expenses incurred or
made by it in addition to the compensation for its services. Such expenses shall
include the reasonable compensation, disbursements and expenses of the Trustee's
agents and counsel.

         The Company shall indemnify the Trustee against any and all losses,
liabilities or expenses incurred by it arising out of or in connection with the
acceptance or administration of its duties under this Indenture, including the
costs and expenses of enforcing this Indenture against the Company (including
this Section 7.07) and defending itself against any claim (whether asserted by
the Company or any Holder or any other person) or liability in connection with
the exercise or performance of any of its powers or duties hereunder, except to
the extent any such loss, liability or expense may be attributable to its
negligence or bad faith. The Trustee shall notify the Company promptly of any
claim for which it may seek indemnity. Failure by the Trustee to so notify the

                                       58


Company shall not relieve the Company of its obligations hereunder. The Company
shall defend the claim and the Trustee shall cooperate in the defense. The
Trustee may have separate counsel and the Company shall pay the reasonable fees
and expenses of such counsel. The Company need not pay for any settlement made
without its consent, which consent shall not be unreasonably withheld.

         The obligations of the Company under this Section 7.07 shall survive
the satisfaction and discharge of this Indenture.

         To secure the Company's payment obligations in this Section, the
Trustee shall have a Lien prior to the Bonds on all money or property held or
collected by the Trustee, except that held in trust to pay principal and
interest on particular Bonds. Such Lien shall survive the satisfaction and
discharge of this Indenture.

         When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.01(h) or (i) hereof occurs, the expenses and the
compensation for the services (including the fees and expenses of its agents and
counsel) are intended to constitute expenses of administration under any
Bankruptcy Law.

         The Trustee shall comply with the provisions of TIA ss. 313(b)(2) to
the extent applicable.

SECTION 7.08.  REPLACEMENT OF TRUSTEE.

         A resignation or removal of the Trustee and appointment of a successor
Trustee shall become effective only upon the successor Trustee's acceptance of
appointment as provided in this Section.

         The Trustee may resign in writing at any time and be discharged from
the trust hereby created by so notifying the Company. The Holders of Bonds of a
majority in principal amount of the then outstanding Bonds may remove the
Trustee by so notifying the Trustee and the Company in writing. The Company may
remove the Trustee if:

         (a) the Trustee fails to comply with Section 7.10 hereof;

         (b) the Trustee is adjudged a bankrupt or an insolvent or an order for
relief is entered with respect to the Trustee under any Bankruptcy Law;

         (c) a Custodian or public officer takes charge of the Trustee or its
property; or

         (d) the Trustee becomes incapable of acting.

         If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, the Company shall promptly appoint a successor
Trustee. Within one year after the successor Trustee takes office, the Holders
of a majority in principal amount of the then outstanding Bonds may appoint a
successor Trustee to replace the successor Trustee appointed by the Company.

                                       59


         If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company, or
the Holders of Bonds of at least 10% in principal amount of the then outstanding
Bonds may petition any court of competent jurisdiction for the appointment of a
successor Trustee.

         If the Trustee, after written request by any Holder of a Bond who has
been a Holder of a Bond for at least six months, fails to comply with Section
7.10, such Holder of a Bond may petition any court of competent jurisdiction for
the removal of the Trustee and the appointment of a successor Trustee.

         A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon, the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to Holders of the Bonds. The retiring Trustee shall promptly transfer
all property held by it as Trustee to the successor Trustee, provided all sums
owing to the Trustee hereunder have been paid and subject to the Lien provided
for in Section 7.07 hereof. Notwithstanding replacement of the Trustee pursuant
to this Section 7.08, the Company's obligations under Section 7.07 hereof shall
continue for the benefit of the retiring Trustee.

SECTION 7.09.  SUCCESSOR TRUSTEE BY MERGER, ETC.

         If the Trustee consolidates, merges or converts into, or transfers all
or substantially all of its corporate trust business to, another corporation,
the successor corporation without any further act shall be the successor
Trustee.

SECTION 7.10.  ELIGIBILITY; DISQUALIFICATION.

         There shall at all times be a Trustee hereunder that is a corporation
organized and doing business under the laws of the United States of America or
of any state thereof that is authorized under such laws to exercise corporate
trustee power, that is subject to supervision or examination by federal or state
authorities and that has a combined capital and surplus of at least $100 million
as set forth in its most recent published annual report of condition.

         This Indenture shall always have a Trustee who satisfies the
requirements of TIA ss. 310(a)(1), (2) and (5). The Trustee is subject to TIA
ss. 310(b).

SECTION 7.11.  PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

         The Trustee is subject to TIA ss. 311(a), excluding any creditor
relationship listed in TIA ss. 311(b). A Trustee who has resigned or been
removed shall be subject to TIA ss. 311(a) to the extent indicated therein.

                                       60


SECTION 7.12.  RIGHTS AND INDEMNITIES OF COLLATERAL AGENT.

         The rights, protections and indemnities provided to the Trustee herein
shall also be provided, and apply, to State Street Bank and Trust Company, as
Collateral Agent.

                                   ARTICLE 8.
                    LEGAL DEFEASANCE AND COVENANT DEFEASANCE

SECTION 8.01.  OPTION TO EFFECT LEGAL DEFEASANCE OR COVENANT DEFEASANCE.

         The Company may, at the option of its Board of Directors evidenced by a
resolution set forth in an Officers' Certificate, at any time, elect to have
either Section 8.02 or 8.03 hereof be applied to all outstanding Bonds upon
compliance with the conditions set forth below in this Article Eight.

SECTION 8.02.   LEGAL DEFEASANCE AND DISCHARGE.

         Upon the Company's exercise under Section 8.01 hereof of the option
applicable to this Section 8.02, the Company shall, subject to the satisfaction
of the conditions set forth in Section 8.04 hereof, be deemed to have been
discharged from its obligations with respect to all outstanding Bonds on the
date the conditions set forth below are satisfied (hereinafter, "Legal
Defeasance"). For this purpose, Legal Defeasance means that the Company shall be
deemed to have paid and discharged the entire Indebtedness represented by the
outstanding Bonds, which shall thereafter be deemed to be "outstanding" only for
the purposes of Section 8.05 hereof and the other Sections of this Indenture
referred to in (a) and (b) below, and to have satisfied all its other
obligations under such Bonds and this Indenture (and the Trustee, on demand of
and at the expense of the Company, shall execute proper instruments
acknowledging the same), except for the following provisions which shall survive
until otherwise terminated or discharged hereunder: (a) the rights of Holders of
outstanding Bonds to receive solely from the trust fund described in Section
8.04 hereof, and as more fully set forth in such Section, payments in respect of
the principal of, premium, if any, and interest on and Registration Default
Damages, if any, with respect to such Bonds when such payments are due, (b) the
Company's obligations with respect to such Bonds under Article 2 and Section
4.02 hereof, (c) the rights, powers, trusts, duties and immunities of the
Trustee hereunder and the Company's obligations in connection therewith and (d)
this Article Eight. Subject to compliance with this Article Eight, the Company
may exercise its option under this Section 8.02 notwithstanding the prior
exercise of its option under Section 8.03 hereof.

SECTION 8.03.   COVENANT DEFEASANCE.

         Upon the Company's exercise under Section 8.01 hereof of the option
applicable to this Section 8.03, the Company shall, subject to the satisfaction
of the conditions set forth in Section 8.04 hereof, be released from its
obligations under the covenants contained in Sections 4.07, 4.10, 4.08, 4.09,
4.10, 4.11, 4.12, 4.13, 4.15, 4.16, 4.17, 4.18, 4.19, 4.20, 4.21, 4.22, 4.23,
4.24, 4.25, 4.26, 4.27, and 4.28 hereof with respect to the outstanding Bonds on

                                       61


and after the date the conditions set forth in Section 8.04 are satisfied
(hereinafter, "Covenant Defeasance"), and the Bonds shall thereafter be deemed
not "outstanding" for the purposes of any direction, waiver, consent or
declaration or act of Holders (and the consequences of any thereof) in
connection with such covenants, but shall continue to be deemed "outstanding"
for all other purposes hereunder (it being understood that such Bonds shall not
be deemed outstanding for accounting purposes). For this purpose, Covenant
Defeasance means that, with respect to the outstanding Bonds, the Company may
omit to comply with and shall have no liability in respect of any term,
condition or limitation set forth in any such covenant, whether directly or
indirectly, by reason of any reference elsewhere herein to any such covenant or
by reason of any reference in any such covenant to any other provision herein or
in any other document and such omission to comply shall not constitute a Default
or an Event of Default under Section 6.01 hereof, but, except as specified
above, the remainder of this Indenture and such Bonds shall be unaffected
thereby. In addition, upon the Company's exercise under Section 8.01 hereof of
the option applicable to this Section 8.03 hereof, subject to the satisfaction
of the conditions set forth in Section 8.04 hereof, Sections 6.01(c) through
6.01(f) hereof shall not constitute Events of Default.

SECTION 8.04.  CONDITIONS TO LEGAL OR COVENANT DEFEASANCE.

         The following shall be the conditions to the application of either
Section 8.02 or 8.03 hereof to the outstanding Bonds:

In order to exercise either Legal Defeasance or Covenant Defeasance:

         (a) the Company must irrevocably deposit with the Trustee, in trust,
for the benefit of the Holders, cash in United States dollars, non-callable
Government Securities, or a combination thereof, in such amounts as will be
sufficient, in the opinion of a nationally recognized firm of independent public
accountants, to pay the principal of, premium and Registration Default Damages,
if any, and interest on the outstanding Bonds on the stated maturity date for
payment thereof or on the applicable redemption date, as the case may be;

         (b) in the case of an election under Section 8.02 hereof, the Company
shall have delivered to the Trustee an Opinion of Counsel in the United States
reasonably acceptable to the Trustee confirming that (A) the Company has
received from, or there has been published by, the Internal Revenue Service a
ruling or (B) since the date of this Indenture, there has been a change in the
applicable federal income tax law, in either case to the effect that, and based
thereon such Opinion of Counsel shall confirm that, the Holders of the
outstanding Bonds will not recognize income, gain or loss for federal income tax
purposes as a result of such Legal Defeasance and will be subject to federal
income tax on the same amounts, in the same manner and at the same times as
would have been the case if such Legal Defeasance had not occurred;

         (c) in the case of an election under Section 8.03 hereof, the Company
shall have delivered to the Trustee an Opinion of Counsel in the United States
reasonably acceptable to the Trustee confirming that the Holders of the
outstanding Bonds will not recognize income, gain or loss for federal income tax
purposes as a result of such Covenant Defeasance and will be subject to federal

                                       62


income tax on the same amounts, in the same manner and at the same times as
would have been the case if such Covenant Defeasance had not occurred;

          (d) no Default or Event of Default shall have occurred and be
continuing on the date of such deposit (other than a Default or Event of Default
resulting from the incurrence of Indebtedness all or a portion of the proceeds
of which will be used to defease the Bonds pursuant to this Article Eight
concurrently with such incurrence) or insofar as Sections 6.01(h) or 6.01(i)
hereof is concerned, at any time in the period ending on the 91st day after the
date of deposit;

          (e) such Legal Defeasance or Covenant Defeasance shall not result
in a breach or violation of, or constitute a default under, any material
agreement or instrument (other than this Indenture) to which the Company or any
of its Subsidiaries is a party or by which the Company or any of its
Subsidiaries is bound;

          (f) the Company shall have delivered to the Trustee an Opinion of
Counsel (which may be subject to customary exceptions) to the effect that on the
91st day following the deposit, the trust funds will not be subject to the
effect of any applicable bankruptcy, insolvency, reorganization or similar laws
affecting creditors' rights generally;

          (g) the Company shall have delivered to the Trustee an Officers'
Certificate stating that the deposit was not made by the Company with the intent
of preferring the Holders over any other creditors of the Company or with the
intent of defeating, hindering, delaying or defrauding any other creditors of
the Company; and

          (h) the Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent provided for or relating to the Legal Defeasance or the Covenant
Defeasance have been complied with.

SECTION 8.05.  DEPOSITED MONEY AND GOVERNMENT  SECURITIES TO BE HELD IN TRUST; 
OTHER  MISCELLANEOUS PROVISIONS.

         Subject to Section 8.06 hereof, all money and non-callable Government
Securities (including the proceeds thereof) deposited with the Trustee (or other
qualifying trustee, collectively for purposes of this Section 8.05, the
"Trustee") pursuant to Section 8.04 hereof in respect of the outstanding Bonds
shall be held in trust and applied by the Trustee, in accordance with the
provisions of such Bonds and this Indenture, to the payment, either directly or
through any Paying Agent (including the Company acting as Paying Agent) as the
Trustee may determine, to the Holders of such Bonds of all sums due and to
become due thereon in respect of principal, premium, if any, and interest, but
such money need not be segregated from other funds except to the extent required
by law or by Section 2.04 and Article X hereof.

         The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the cash or non-callable Government
Securities deposited pursuant to Section 8.04 hereof or the principal and

                                       63


interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the Holders of the outstanding Bonds.

         Anything in this Article Eight to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon the request
of the Company any money or non-callable Government Securities held by it as
provided in Section 8.04 hereof which, in the opinion of a nationally recognized
firm of independent public accountants expressed in a written certification
thereof delivered to the Trustee (which may be the opinion delivered under
Section 8.04(a) hereof), are in excess of the amount thereof that would then be
required to be deposited to effect an equivalent Legal Defeasance or Covenant
Defeasance.

SECTION 8.06.  REPAYMENT TO COMPANY.

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of, premium, if any,
or interest on any Bond and remaining unclaimed for two years after such
principal, and premium, if any, or interest has become due and payable shall be
paid to the Company on its written request or (if then held by the Company)
shall be discharged from such trust; and the Holder of such Bond shall
thereafter, as a secured creditor, look only to the Company for payment thereof,
and all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being
required to make any such repayment, may at the expense of the Company cause to
be published once, in the New York Times and The Wall Street Journal (national
edition), notice that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30 days from the date of such
notification or publication, any unclaimed balance of such money then remaining
will be repaid to the Company.

SECTION 8.07.  REINSTATEMENT.

         If the Trustee or Paying Agent is unable to apply any United States
dollars or non-callable Government Securities in accordance with Section 8.02 or
8.03 hereof, as the case may be, by reason of any order or judgment of any court
or governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Company's obligations under this Indenture and the Bonds
shall be revived and reinstated as though no deposit had occurred pursuant to
Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is
permitted to apply all such money in accordance with Section 8.02 or 8.03
hereof, as the case may be; provided, however, that, if the Company makes any
payment of principal of, premium, if any, or interest on any Bond following the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of such Bonds to receive such payment from the money held by the
Trustee or Paying Agent.

                                       64


                                   ARTICLE 9.
                        AMENDMENT, SUPPLEMENT AND WAIVER

SECTION 9.01.  WITHOUT CONSENT OF HOLDERS OF BONDS.

         Notwithstanding Section 9.02 of this Indenture, the Company, NE LP, NE
LLC and the Trustee may amend or supplement this Indenture and the other
Financing Agreements (other than the Pledge Agreements, which may be amended by
the parties thereto for the purposes that follow) or the Bonds without the
consent of any Holder of a Bond:

         (a) to cure any ambiguity, defect or inconsistency;

         (b) to provide for uncertificated Bonds in addition to or in place
of certificated Bonds or to alter the provisions of Article 2 hereof (including
the related definitions) in a manner that does not materially adversely affect
any Holder;

         (c) to provide for the assumption of the Company's obligations to the
Holders of the Bonds by a successor to the Company pursuant to Article 5 hereof;

         (d) to make any change that would provide any additional rights or
benefits to the Holders of the Bonds or that does not adversely affect the legal
rights hereunder of any Holder of the Bond; or

         (e) to comply with requirements of the SEC in order to effect or
maintain the qualification of this Indenture under the TIA;

         Upon the request of the Company accompanied by a resolution of its
Board of Directors authorizing the execution of any such amended or supplemental
Indenture, and upon receipt by the Trustee of the documents described in Section
7.02 hereof, the Trustee shall join with the Company, NE LP and NE LLC in the
execution of any amended or supplemental Indenture authorized or permitted by
the terms of this Indenture and to make any further appropriate agreements and
stipulations that may be therein contained, but the Trustee shall not be
obligated to enter into such amended or supplemental Indenture that affects its
own rights, duties or immunities under this Indenture or otherwise.

SECTION 9.02.  WITH CONSENT OF HOLDERS OF BONDS.

         Except as provided below in this Section 9.02, the Company and the
Trustee may amend or supplement this Indenture (including Section 4.15 hereof),
and the other Financing Agreements and the Bonds may be amended or supplemented,
and with the consent of the Holders of at least a majority in principal amount
of the Bonds then outstanding voting as a single class (including consents
obtained in connection with a tender offer or exchange offer for, or purchase
of, the Bonds), and, subject to Sections 6.04 and 6.07 hereof, any existing
Default or Event of Default (other than a Default or Event of Default in the
payment of the principal of, premium, if any, or interest on or Registration
Default Damages with respect to the Bonds, except a payment default resulting
from an acceleration that has been rescinded) or compliance with any provision
of this Indenture, the other Financing Agreements or the Bonds may be waived

                                       65


with the consent of the Holders of a majority in principal amount of the then
outstanding Bonds voting as a single class (including consents obtained in
connection with a tender offer or exchange offer for, or purchase of, the
Bonds).

         Upon the request of the Company accompanied by a resolution of its
Board of Directors authorizing the execution of any such amended or supplemental
Indenture, and upon the filing with the Trustee of evidence satisfactory to the
Trustee of the consent of the Holders of Bonds as aforesaid, and upon receipt by
the Trustee of the documents described in Section 7.02 hereof, the Trustee shall
join with the Company in the execution of such amended or supplemental Indenture
unless such amended or supplemental Indenture directly affects the Trustee's own
rights, duties or immunities under this Indenture or otherwise, in which case
the Trustee may in its discretion, but shall not be obligated to, enter into
such amended or supplemental Indenture.

         It shall not be necessary for the consent of the Holders of Bonds under
this Section 9.02 to approve the particular form of any proposed amendment or
waiver, but it shall be sufficient if such consent approves the substance
thereof.

         After an amendment, supplement or waiver under this Section becomes
effective, the Company shall mail to the Holders of Bonds affected thereby a
notice briefly describing the amendment, supplement or waiver. Any failure of
the Company to mail such notice, or any defect therein, shall not, however, in
any way impair or affect the validity of any such amended or supplemental
Indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a
majority in aggregate principal amount of the Bonds then outstanding voting as a
single class may waive compliance in a particular instance by the Company with
any provision of this Indenture or the Bonds. However, without the consent of
each Holder affected, an amendment or waiver under this Section 9.02 may not
(with respect to any Bonds held by a non-consenting Holder):

         (a) reduce the principal amount of Bonds whose Holders must consent to
an amendment, supplement or waiver;

         (b) reduce the principal of or change the fixed maturity of any Bond or
alter or waive any of the provisions with respect to extraordinary or optional
redemption of the Bonds except as provided above with respect to Sections 4.15
hereof;

         (c) reduce the rate of or change the time for payment of interest,
including default interest, on any Bond;

         (d) waive a Default or Event of Default in the payment of principal of
or premium, if any, or interest or Registration Default Damages, if any, on the
Bonds (except a rescission of acceleration of the Bonds by the Holders of at
least a majority in aggregate principal amount of the then outstanding Bonds and
a waiver of the payment default that resulted from such acceleration);

                                       66


         (e) make any Bond payable in money other than that stated in the Bonds;

         (f) make any change in the provisions of this Indenture relating to
waivers of past Defaults or the rights of Holders of Bonds to receive payments
of principal of or premium, if any, or interest or Registration Default Damages,
if any or Registration Default Damages, if any, on the Bonds;

         (g) waive a redemption payment with respect to any Bond (other than a
payment required by Section 4.15 hereof;

         (h) make a change in or waive the security provisions of any of the
Financing Agreements;

         (i) make change in or waive the applicability of the Bond Guaranty; and

         (j) make any change in Section 6.04 or 6.07 hereof or in the foregoing
amendment and waiver provisions.

SECTION 9.03.  COMPLIANCE WITH TRUST INDENTURE ACT.

         Every amendment or supplement to this Indenture or the Bonds shall be
set forth in a amended or supplemental Indenture that complies with the TIA as
then in effect.

SECTION 9.04.  REVOCATION AND EFFECT OF CONSENTS.

         Until an amendment, supplement or waiver becomes effective, a consent
to it by a Holder of a Bond is a continuing consent by the Holder of a Bond and
every subsequent Holder of a Bond or portion of a Bond that evidences the same
debt as the consenting Holder's Bond, even if notation of the consent is not
made on any Bond. However, any such Holder of a Bond or subsequent Holder of a
Bond may revoke the consent as to its Bond if the Trustee receives written
notice of revocation before the date the waiver, supplement or amendment becomes
effective. An amendment, supplement or waiver becomes effective in accordance
with its terms and thereafter binds every Holder.

SECTION 9.05.  NOTATION ON OR EXCHANGE OF BONDS.

         The Trustee may place an appropriate notation about an amendment,
supplement or waiver on any Bond thereafter authenticated. The Company in
exchange for all Bonds may issue and the Trustee shall, upon receipt of an
Authentication Order, authenticate new Bonds that reflect the amendment,
supplement or waiver.

         Failure to make the appropriate notation or issue a new Bond shall not
affect the validity and effect of such amendment, supplement or waiver.


                                       67


SECTION 9.06.  TRUSTEE TO SIGN AMENDMENTS, ETC.

         The Trustee shall sign any amended or supplemental Indenture authorized
pursuant to this Article Nine if the amendment or supplement does not adversely
affect the rights, duties, liabilities or immunities of the Trustee. The Company
may not sign an amendment or supplemental Indenture until the Board of Directors
approves it. In executing any amended or supplemental indenture, the Trustee
shall be entitled to receive and (subject to Section 7.01 hereof) shall be fully
protected in relying upon, in addition to the documents required by Section
13.04 hereof, an Officer's Certificate and an Opinion of Counsel stating that
the execution of such amended or supplemental indenture is authorized or
permitted by this Indenture.

                  (i)      Revenues Account;

                  (ii)     Debt Service Account;

                  (iii)    Debt Service Reserve Account; and

                  (iv)     Distribution Account.

         (b) All Accounts are hereby pledged to the Trustee for its benefit, the
benefit of the Collateral Agent and the ratable benefit of the Holders of the
Bonds and shall be under the exclusive dominion and control of the Trustee and,
except as expressly provided herein, none of the Company, NE LP or NE LLC shall
have any right to withdraw funds from any Account. Each of NE LP and NE LLC
hereby irrevocably authorizes the Trustee to receive and deposit all Revenues
into an account designated the "Revenues Account" and to withdraw and transfer
funds from the Revenues Account on a monthly basis on the first Business Day of
each month (the "Transfer Date") in the order of priority set forth in Sections
10.02 hereof, in accordance with the terms of this Indenture.

SECTION 10.02. REVENUES ACCOUNT.

         (a) Without limitation of any other amounts required under this
Indenture to be deposited in the Revenues Account, NE LP and NE LLC shall
deposit and/or cause to be deposited all Revenues with the Trustee in the
Revenues Account and in furtherance thereof NE LP, NE LLC and, if applicable,
the Company, shall instruct each Person from whom it receives or is entitled to
receive Revenues to pay such Revenues (identifying them as such) directly to the
Trustee for deposit in the Revenues Account, and the Trustee shall be entitled
to receive directly all Revenues from the Persons owing the same but except in

                                       68


its capacity as trustee under the Project Indenture shall have no obligation
otherwise with respect to the collection thereof. In the event that any Revenues
are remitted directly to, or otherwise received by, any of NE LP, NE LLC or the
Company, as the case may be, such Person shall hold such Revenues in trust for
the Trustee and shall promptly remit such Revenues, in the form received (with
any necessary endorsement) to the Trustee for deposit in the Revenues Account.

         (b) On each Transfer Date, the Trustee shall make the following
transfers from funds then on deposit in the Revenues Account (after giving
effect to all transfers to be made to the Revenues Account on such date) in the
respective amounts, and in the order of priority, set forth below:

                  (i) first, to an account designated the "Debt Service
         Account", into which shall be deposited an amount equal to the
         difference between (i) the amount then on deposit therein and (ii) the
         aggregate amount of principal, premium, if any, interest on and
         Registration Default Damages, if any, scheduled to be paid in respect
         of the Bonds on the next semi-annual payment date and any trustee,
         registration or other administrative expenses, as certified by the
         Company to the Trustee and not exceeding $10,000 in any semi-annual
         period, due during the next six months. The Trustee shall apply the
         funds on deposit in the Debt Service Account to make payments on the
         Bonds when due and to pay up to $10,000 of trustee, registration or
         other administrative expenses with respect to the Bonds when due.

                  (ii) second, to an account designated the "Debt Service
         Reserve Account," into which shall be deposited an amount equal to the
         difference between (i) the sum of the amount then on deposit therein
         and the undrawn amount of any Acceptable Credit Support credited
         thereto and (ii) the aggregate principal, premium, if any, interest on
         and Registration Default Damages, if any, scheduled to be paid with
         respect of the Bonds on the next semi-annual payment date (the
         "Required DSRA Balance"). The Trustee shall apply the funds on deposit
         in the Debt Service Reserve Account (including any amounts available to
         be drawn under Acceptable Credit Support credited thereto after cash
         then on deposit therein has been exhausted) to pay amounts due and
         payable in respect of the Bonds to the extent that on a semi annual
         payment date there are insufficient funds in the Debt Service Account
         to do so; and

                  (iii) finally, any amount remaining in the Revenues Account
         will be transferred to an account designated the "Distribution Account"
         if and only if, at the time of and after giving effect to such transfer
         and the deemed removal of funds from the Distribution Account pursuant
         to Section 4.07:

                           (x) the Debt Service Account and Debt Service Reserve
                  Account are funded to their then required levels;

                           (y) no Default or Event of Default under the
                  Indenture has occurred and is continuing or would occur as a
                  consequence thereof; and

                                       69


                           (z) the Debt Service Coverage Ratio and the Projected
                  Debt Service Coverage Ratio equal or exceed 1.4 to 1, provided
                  that, in calculating the Debt Service Coverage Ratio for
                  purposes of this clause (c) at any time prior to December 30,
                  1998, the Operating Revenues received and scheduled debt
                  service payment referred to in clauses (i) and (ii) of the
                  definition thereof shall be measured for the period of months
                  that has elapsed from the date of the Acquisitions to the date
                  of such calculations.

         Notwithstanding the foregoing, no funds shall be permitted to be
transferred to the Distribution Account prior to June 30, 1998. Thereafter, on
any Transfer Date, promptly upon receipt by the Trustee of an Officer
Certificate and other documents required pursuant to Section 4.07, the Trustee
shall be authorized and directed to release moneys in the Distribution Account
to or at the direction of NE LP.

SECTION 10.03. ACCEPTABLE CREDIT SUPPORT.

         (a) Provided that no Default or Event of Default has occurred and
is continuing and subject to clauses (b) and (c) below, the Company may in
writing, accompanied by the documents required by Section 13.04, request payment
to it of all or a portion of the cash deposited or required to be deposited in
the Debt Service Reserve Account upon the deposit of Acceptable Credit Support
in an equal amount. Upon such Deposit of Acceptable Credit Support and receipt
by the Trustee of such written request, the Trustee shall be authorized and
directed to release such replaced cash to or at the direction of NE LP.

         (b) The Trustee shall be the beneficiary under any letter of
credit and under any Guarantee constituting Acceptable Credit Support, and any
Acceptable Credit Support shall allow drawings by the Trustee and the Trustee
shall draw upon such Acceptable Credit Support if it is not renewed at least 30
days prior to its expiration date or if the ratings of any guarantor or letter
of credit issuer fall below the required levels and alternative Acceptable
Credit Support or cash is not provided to the Trustee within 15 days thereafter.
If at any semi-annual interest payment date, the funds then on deposit in the
Debt Service Account are insufficient to cover the payments set forth in Section
10.02(b)(i) hereof, the Trustee shall apply the funds then on deposit in the
Revenues Account and, if still insufficient, the funds then on deposit in the
Debt Service Reserve Account as provided in Section 10.02(b)(ii) hereof and/or
if on any semi-annual interest payment date, the funds then on deposit in the
Debt Service Reserve Account are insufficient to cover the Required DSRA Balance
pursuant to Section 10.02(b)(ii) hereof, the Trustee is hereby authorized to
transfer the funds on deposit in the Revenues Account and, if still
insufficient, to draw upon such Acceptable Credit Support pro rata (if more than
one) or otherwise in accordance with the terms of such Acceptable Credit Support
(after cash then on deposit therein has been exhausted).

         (c) The issuer of or account party to any letter of credit or
Guarantee shall have rights of subrogation against the Company, NE LP or NE LLC
so long as (a) the Obligations of the Company, NE LP and NE LLC in respect
thereof are subordinated to the repayment of the Bond Loan and the Bonds and are
payable only to the extent Restricted Payments can be made and (b) such issuer

                                       70


or account party waives its rights to exercise remedies in respect of such
Obligations so long as the Bonds are outstanding.

SECTION 10.04. INITIAL DEPOSIT OF CASH OR ACCEPTABLE CREDIT SUPPORT.

Article 10 into the Debt Service Reserve Account.

         (a) NE LP and NE LLC each hereby pledges and grants to the Trustee
as Collateral Agent for its benefit (as Trustee and Collateral Agent) and for
the ratable benefit of the Holders of Bonds, a continuing first priority
security interest in all of its right, title and interest in the Accounts and in

NE LLC under the Indenture and (iii) NE LP under the Note and the Bond Guaranty.
The Trustee is hereby authorized to invest the funds on deposit in the Accounts

Agent may (but shall be under no obligation to) exercise any and all rights and
remedies granted to a "secured party" under the Uniform Commercial Code of the
State of New York.

Partnership, second priority) Lien in and on all the Pledged Collateral in favor
of the Collateral Agent for its benefit, the benefit of the Trustee and the
ratable benefit of the Holders of the Bonds, superior to and prior to the rights

Collateral (including power to institute and maintain suits or proceedings to
restrain the enforcement of or compliance with any legislative or other

                                   ARTICLE 12.
                                  BOND GUARANTY

SECTION 12.01. BOND GUARANTY.

         Subject to this Article 12, NE LP hereby unconditionally guarantees to
each Holder of a Bond authenticated and delivered by the Trustee and to the
Trustee and its successors and assigns, irrespective of the validity and
enforceability of this Indenture, the Bonds or the obligations of the Company
hereunder or thereunder, that: (a) the principal of, premium, if any, and
interest on and Registration Default Damages, if any, with respect to the Bonds
will be promptly paid in full when due, whether at maturity, by acceleration,
redemption or otherwise, and interest on the overdue principal of and interest
on the Bonds, if any, if lawful, and all other obligations of the Company to the
Holders or the Trustee hereunder or thereunder will be promptly paid in full or
performed, all in accordance with the terms hereof and thereof; and (b) in case
of any extension of time of payment or renewal of any Bonds or any of such other
obligations, that same will be promptly paid in full when due or performed in
accordance with the terms of the extension or renewal, whether at stated
maturity, by acceleration or otherwise. Failing payment when due of any amount
so guaranteed or any performance so guaranteed for whatever reason, NE LP shall
be obligated to pay the same immediately. NE LP agrees that this is a guarantee
of payment and not a guarantee of collection.

         NE LP hereby agrees that its obligations hereunder shall be
unconditional, irrespective of the validity, regularity or enforceability of the
Bonds or this Indenture, the absence of any action to enforce the same, any
waiver or consent by any Holder of the Bonds with respect to any provisions
hereof or thereof, the recovery of any judgment against the Company, any action
to enforce the same or any other circumstance which might otherwise constitute a
legal or equitable discharge or defense of a guarantor. NE LP hereby waives
diligence, presentment, demand of payment, filing of claims with a court in the
event of insolvency or bankruptcy of the Company, any right to require a
proceeding first against the Company, protest, notice and all demands whatsoever
and covenant that this Bond Guaranty shall not be discharged except by complete
performance of the obligations contained in the Bonds and this Indenture.

         If any Holder or the Trustee is required by any court or otherwise to
return to the Company, NE LP, NE LLC or any custodian, trustee, liquidator or
other similar official acting in relation to either the Company, NE LP or NE

                                       75


LLC, any amount paid by either to the Trustee or such Holder, this Bond
Guaranty, to the extent theretofore discharged, shall be reinstated in full
force and effect.

         NE LP agrees that it shall not be entitled to any right of subrogation
in relation to the Holders in respect of any obligations guaranteed hereby until
payment in full of all obligations guaranteed hereby. NE LP further agrees that,
as between NE LP, on the one hand, and the Holders and the Trustee, on the other
hand, (x) the maturity of the obligations guaranteed hereby may be accelerated
as provided in Article 6 hereof for the purposes of this Bond Guaranty,
notwithstanding any stay, injunction or other prohibition preventing such
acceleration in respect of the obligations guaranteed hereby, and (y) in the
event of any declaration of acceleration of such obligations as provided in
Article 6 hereof, such obligations (whether or not due and payable) shall
forthwith become due and payable by NE LP for the purpose of this Bond Guaranty.

SECTION 12.02. LIMITATION ON GUARANTOR LIABILITY.

         NE LP, and by its acceptance of Bonds, each Holder, hereby confirms
that it is the intention of all such parties that the Bond Guaranty of NE LP not
constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law,
the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or
any similar federal or state law to the extent applicable to any Bond Guaranty.
To effectuate the foregoing intention, the Trustee, the Holders and NE LP hereby
irrevocably agree that the obligations of NE LP under its Bond Guaranty and this
Article 12 shall be limited to the maximum amount as will, after giving effect
to such maximum amount and all other contingent and fixed liabilities of NE LP
that are relevant under such laws, and after giving effect to any collections
from, rights to receive contribution from or payments made by or on behalf of
any other Guarantor, if any, in respect of the obligations of such other
Guarantor, if any, under this Article 12, result in the obligations of NE LP
under its Bond Guaranty not constituting a fraudulent transfer or conveyance.

SECTION 12.03. EXECUTION AND DELIVERY OF BOND GUARANTY.

         To evidence its Bond Guaranty set forth in Section 12.01, NE LP hereby
agrees that a notation of such Bond Guaranty substantially in the form included
in Exhibit E shall be endorsed by an Officer of NE LP on each Bond authenticated
and delivered by the Trustee and that this Indenture shall be executed on behalf
of NE LP by its President or one of its Vice Presidents.

         NE LP hereby agrees that its Bond Guaranty set forth in Section 12.01
shall remain in full force and effect notwithstanding any failure to endorse on
each Bond a notation of such Bond Guaranty.

         If an Officer whose signature is on this Indenture or on the Bond
Guaranty no longer holds that office at the time the Trustee authenticates the
Bond on which a Bond Guaranty is endorsed, the Bond Guaranty shall be valid
nevertheless.

                                       76


         The delivery of any Bond by the Trustee, after the authentication
thereof hereunder, shall constitute due delivery of the Bond Guaranty set forth
in this Indenture on behalf of the NE LP.

         In the event that the Company, NE LP or NE LLC creates or acquires any
new Subsidiaries subsequent to the date of this Indenture, if required by
Section 4.24 hereof, the Company, NE LP and NE LLC shall cause such Subsidiaries
to execute supplemental indentures to this Indenture and Bond Guaranty in
accordance with Section 4.24 hereof and this Article 12, to the extent
applicable.

SECTION 12.04. GUARANTOR'S MERGER, CONSOLIDATION, ETC.

         NE LP may not, nor may any other future Guarantor, if any, consolidate
with or merge with or into (whether or not NE LP or such Guarantor is the
surviving Person) another Person whether or not affiliated with such Guarantor
except as expressly permitted under and subject to conditions set forth in
Section 5.01 hereof.

         In case of any such consolidation, merger, sale or conveyance and upon
the assumption by the successor Person, by supplemental indenture, executed and
delivered to the Trustee and satisfactory in form to the Trustee, of the Bond
Guaranty endorsed upon the Bonds and the due and punctual performance of all of
the covenants and conditions of this Indenture to be performed by NE LP and any
other future Guarantor, if any, such successor Person shall succeed to and be
substituted for NE LP and any other future Guarantor, if any, the with the same
effect as if it had been named herein as a Guarantor. Such successor Person
thereupon may cause to be signed any or all of the Bond Guarantees to be
endorsed upon all of the Bonds issuable hereunder which theretofore shall not
have been signed by the Company and delivered to the Trustee. All the Bond
Guarantees so issued shall in all respects have the same legal rank and benefit
under this Indenture as the Bond Guarantees theretofore and thereafter issued in

                                      A1-2



         1. INTEREST. ESI Tractebel Acquisition Corp., a Delaware corporation
(the "Company"), promises to pay interest on the principal amount of this Bond
at 7.99% per annum from the date of issuance until maturity and shall pay the
Registration Default Damages, if any, payable pursuant to Section 5 of the
Registration Rights Agreement referred to below. The Company will pay interest
and Registration Default Damages semi-annually on June 30 and December 30 of
each year, or if any such day is not a Business Day, on the next succeeding
Business Day (each an "Interest Payment Date"). Interest on the Bonds will
accrue from the most recent date to which interest has been paid or, if no
interest has been paid, from the date of issuance; provided that if there is no
existing Default in the payment of interest, and if this Bond is authenticated
between a record date referred to on the face hereof and the next succeeding
Interest Payment Date, interest shall accrue from such next succeeding Interest
Payment Date; provided, further, that the first Interest Payment Date shall be
June 30, 1998. The Company shall pay interest (including post-petition interest
in any proceeding under any Bankruptcy Law) on overdue principal and premium, if
any, from time to time on demand at a rate that is 1% per annum in excess of the
rate then in effect; it shall pay interest (including post-petition interest in
any proceeding under any Bankruptcy Law) on overdue installments of interest and
Registration Default Damages (without regard to any applicable grace periods)
from time to time on demand at the same rate to the extent lawful. Interest will
be computed on the basis of a 360-day year of twelve 30-day months.

         2. METHOD OF PAYMENT. The Company will pay interest on the Bonds
(except defaulted interest) and Registration Default Damages to the Persons who
are registered Holders of Bonds at the close of business on the June 15 or
December 15 next preceding the Interest Payment Date, even if such Bonds are
canceled after such record date and on or before such Interest Payment Date,
except as provided in Section 2.12 of the Indenture with respect to defaulted
interest. The Bonds will be payable as to principal, premium and Registration
Default Damages, if any, and interest at the office or agency of the Paying
Agent maintained for such purpose within or without the City and State of New
York, or, at the option of the Company, payment of interest and Registration
Default Damages may be made by check mailed to the Holders at their addresses
set forth in the register of Holders, and provided that payment by wire transfer
of immediately available funds will be required with respect to principal of and
interest, premium and Registration Default Damages on, all Global Bonds and all
other Bonds the Holders of which shall have provided wire transfer instructions
to the Company or the Paying Agent. Such payment shall be in such coin or
currency of the United States of America as at the time of payment is legal
tender for payment of public and private debts.

         3. PAYING AGENT AND REGISTRAR. Initially, State Street Bank and Trust
Company, the Trustee under the Indenture, will act as Paying Agent and
Registrar. The Company may change any Paying Agent or Registrar without notice
to any Holder. The Company or NE LP may act as Registrar but shall not act as
Paying Agent.

         4. INDENTURE AND PLEDGE AGREEMENTS. The Company issued the Bonds under
an Indenture dated as of February 19, 1998 ("Indenture") among the Company, NE
LP and NE LLC and the Trustee. The terms of the Bonds include those stated in

Indenture shall govern and be controlling. The Bonds are secured obligations of
the Company limited to $220 million in aggregate principal amount, plus amounts,
if any, issued to pay Registration Default Damages on outstanding Bonds as set
forth in Paragraph 2 hereof. The Bonds are secured by a pledge of (a) the
perfected, first priority pledge by NE LP to the Trustee, for the benefit of the
Trustee and the Holders of the Bonds, (i) NE LP's 100% member interest in NE LLC
and (ii) NE LP's 98% limited partner interest in each of NEA and NJEA; (b) the
second priority pledge by NE LP to the Trustee, for the benefit of the Trustee
and the Holders of the Bond, of NE LP's one percent general partner interest in
each of NEA and NJEA; (c) the perfected, first priority pledge by NE LLC to the
Trustee, for the benefit of the Trustee and the Holders of the Bond, of NE LLC's
one percent limited partner interest in each of NEA and NJEA; (d) the perfected,
first priority pledge by the Company to the Trustee, for the benefit of the
Trustee and the Holders of the Bonds, of the Note evidencing the Bond Loan. In
addition, the Bonds are secured by a perfected, first priority lien on the
Accounts and all funds deposited therein and all Permitted Investments credited
thereto granted to the Trustee and the Collateral Agent, for the benefit of the
Trustee, the Collateral Agent and the Holders of the Bonds, by NE LP and NE LLC
pursuant to the Indenture. The Bonds are also secured by (a) the perfected,
first priority pledge by each of ESI Northeast Energy GP, Inc., ESI Northeast
Energy LP, Inc., Tractebel Associates Northeast LP, Inc. and Tractebel Northeast
Generation GP, Inc. (collectively, the "Sponsor Affiliates") to the Trustee, as
collateral agent (in such capacity, the Collateral Agent") for the benefit of
the Collateral Agent, the Trustee and the Holders of the Bonds, of all of such
Sponsor Affiliate's partner interests in NE LP and (b) a perfected, first
priority pledge by each owner of the Company to the Collateral Agent, for the
benefit of the Collateral Agent, the Trustee and the Holders of the Bonds, of
all of the outstanding Capital Stock of the Company pursuant to the Sponsor
Pledge Agreement referred to in the Indenture (together with the Company and
Partner Pledge Agreement, the "Pledge Agreement"). The Pledge Agreements will
secure the payment and performance when due of all of the Obligations of the
Company under the Indenture and the Bonds, and of NE LP's obligations under the
Note and the Bond Guaranty, as provided in the Indenture and the Pledge
Agreements.

         6. MANDATORY REDEMPTION; EXTRAORDINARY MANDATORY REDEMPTION

         Except as set forth in this paragraph and in paragraph 7 below and
except for the payment of the principal of the Bonds in semiannual installments
to the Holders thereof, the Company shall not be required to make mandatory
redemption or sinking fund payments with respect to the Bonds. The Company shall
be required to redeem the Bonds, pro rata, at a redemption price equal to the
outstanding principal amount thereof plus accrued and unpaid interest and any
Registration Default Damages to the date fixed for redemption if (1) (a) an
event occurs which triggers the mandatory redemption or repurchase of any or all
of the Project Securities pursuant to the terms of the Project Indenture and (b)
any funds so required to be applied to such redemption or repurchase remain
after giving effect to such redemption or repurchase of Project Securities, and
such excess funds equal at least $2 million and are distributed to NE LP or NE
LLC or (2) a buyout or similar payment is made to a Partnership under any Power
Purchase Agreement and any such funds are distributed to NE LP or NE LLC in
accordance with the terms of the Project Indenture and terms of the Indenture,
provided that, in each such case, only such funds so distributed must be applied
to the extraordinary mandatory redemption.

         7. REPURCHASE AT OPTION OF HOLDER.

         Upon the occurrence of a Change of Control (which shall not occur if
Moody's and S&P confirm that the then existing ratings of the Bonds will not be
lowered as a result of any of the events that, in the absence of such confirmed
rating, would constitute a Change of Control), the Company shall offer to each
Holder to repurchase all or any part (equal to $100,000 or an integral multiple
of $1,000 in excess thereof) of such Holder's Bonds pursuant to the offer
described below (the "Change of Control Offer") at a purchase price in cash
equal to 101% of the aggregate principal amount thereof plus accrued and unpaid
interest and Registration Default Damages thereon, if any, to the date of
purchase (the "Change of Control Payment"). Within ten days following any Change
of Control, the Company shall mail a notice to each Holder describing the
transaction or transactions that constitute the Change of Control and offering
to repurchase Bonds on the date specified in such notice, which date shall be no
earlier than 30 days and no later than 60 days from the date such notice is
mailed (the "Change of Control Payment Date"), pursuant to the procedures
required by the Indenture and described in such notice. The Company shall comply
with the requirements of Rule 14e-1 under the Exchange Act and any other
securities laws and regulations thereunder to the extent such laws and
regulations are applicable in connection with the repurchase of the Bonds as a
result of a Change of Control.

                                      A1-5


         8. NOTICE OF REDEMPTION. Subject to the book entry system
described in the Indenture, if less than all of the Bonds are to be redeemed or
purchased in an offer to purchase at any time, the Trustee shall select the
Bonds to be redeemed or purchased among the Holders of the Bonds in compliance
with the requirements of the principal national securities exchange, if any, on
which the Bonds are listed or, if the Bonds are not so listed, on a pro rata
basis, by lot or in accordance with any other method the Trustee considers fair
and appropriate; provided that, except in the case of an extraordinary mandatory
redemption, no Bonds will be redeemed or purchased in part if the unredeemed
portion will be in an unauthorized denomination. In the event of partial
redemption by lot, the particular Bonds to be redeemed shall be selected, unless
otherwise provided herein, not less than 30 nor more than 60 days prior to the
redemption date by the Trustee from the outstanding Bonds not previously called
for redemption.

         The Trustee shall promptly notify the Company in writing of the Bonds
selected for redemption and, in the case of any Bond selected for partial
redemption, the principal amount thereof to be redeemed. Bonds and portions of
Bonds selected shall be in amounts of $100,000 or whole multiples of $1,000 in
excess thereof; except that if all of the Bonds of a Holder are to be redeemed,
the entire outstanding amount of Bonds held by such Holder, even if not a
multiple of $100,000 or a multiple of $1,000 in excess thereof, shall be
redeemed. Except as provided in the preceding sentence, provisions of this
Indenture that apply to Bonds called for redemption also apply to portions of
Bonds called for redemption.

         9. DENOMINATIONS, TRANSFER, EXCHANGE. The Bonds are in registered
form without coupons in denominations of $100,000 and integral multiples of
$1,000 in excess thereof. The transfer of Bonds may be registered and Bonds may
be exchanged as provided in the Indenture. The Registrar and the Trustee may
require a Holder, among other things, to furnish appropriate endorsements and
transfer documents and the Company may require a Holder to pay any taxes and
fees required by law or permitted by the Indenture. The Company need not
exchange or register the transfer of any Bond or portion of a Bond selected for
redemption, except for the unredeemed portion of any Bond being redeemed in
part. Also, the Company need not exchange or register the transfer of any Bonds
for a period of 15 days before a selection of Bonds to be redeemed or during the
period between a record date and the corresponding Interest Payment Date.

         10. PERSONS DEEMED OWNERS. The registered Holder of a Bond may be
treated as its owner for all purposes.

         11. AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions,
the Indenture, the Bond Guaranty, the other Financing Agreements or the Bonds
may be amended or supplemented with the consent of the Holders of at least a
majority in principal amount of the then outstanding Bonds voting as a single
class, and any existing default (other than a Default or Event of Default in the
payment of the principal of, premium, if any, or interest on or Registration
Default Damages with respect to the Bonds, except a payment default resulting
from acceleration that has been rescinded) or compliance with any provision of
the Indenture, the Bond Guaranty, the other Financing Agreements or the Bonds
may be waived with the consent of the Holders of a majority in principal amount
of the then outstanding Bonds voting as a single class. Without the consent of
any Holder of a Bond, the Indenture, the Bond Guaranty, the other Financing

                                      A1-6


Agreements or the Bonds may be amended or supplemented to cure any ambiguity,
defect or inconsistency; to provide for uncertificated Bonds in addition to or
in place of certificated Bonds or to alter the provisions of Article 2 of the
Indenture (including the related definitions) in a manner that does not
materially adversely affect any Holder; to provide for the assumption of the
Company's obligations to Holders of the Bonds in case of a merger or
consolidation; to make any change that would provide any additional rights or
benefits to the Holders of the Bonds or that does not adversely affect the legal
rights under the Indenture of any such Holder; or to comply with the
requirements of the SEC in order to effect or maintain the qualification of the
Indenture under the Trust Indenture Act.

         12. DEFAULTS AND REMEDIES. Events of Default shall occur, if among
other things: (i) the Company or NE LP, as applicable, defaults in the payment
when due of principal of or premium, if any, on the Bonds or the Note when the
same becomes due and payable at maturity, upon redemption (including in
connection with an offer to purchase) or otherwise and such default continues
for a period of 15 days; (ii) the Company or NE LP, as applicable, defaults in
the payment when due of interest on or Registration Default Damages, if any,
with respect to the Bonds or the Note and such default continues for a period of
15 days; (iii) the Company, NE LP or NE LLC fails to comply with any of the
provisions of Section 4.07, 4.09, 4.15 or 5.01 hereof; (iv) the Company, NE LP
or NE LLC fails to observe or perform any other covenant, representation,
warranty or other agreement in this Indenture, the Bonds or any of the
Collateral Documents to which it is a party for 60 days after notice to the
Company by the Trustee or the Holders of at least 25% in aggregate principal
amount of the Bonds then outstanding voting as a single class; (v) the Company,
NE LP or NE LLC defaults in the payment when due (after giving effect to any
applicable grace periods) of any principal of or premium, if any, or interest on
any Indebtedness (other than the Bonds or the Note) the principal amount of
which exceeds $3 million in the aggregate; (vi) a final judgment or final
judgments for the payment of money are entered by a court or courts of competent
jurisdiction against the Company, NE LP or NE LLC and such judgment or judgments
remain unpaid or, undischarged for a period (during which execution shall not be
effectively stayed) of 60 days, provided that the aggregate of all such
undischarged judgments exceeds $3 million; (vii) Any of the material provisions
of the Collateral Documents shall be held in any judicial proceeding to be
unenforceable or invalid or shall cease for any reason to be in full force and
effect or any lien granted thereby or the priority thereof ceases or fails for
any reason to be in full force and effect (and such unenforceable provisions or
cessation or failure of a lien is not cured within 10 days after the Company, NE
LP or NE LLC has obtained knowledge thereof); (viii) certain events of
bankruptcy or insolvency with respect to the Company, NE LP or NE LLC occurs;
(ix) any limited partnership or limited liability company agreement of NE LP or
NE LLC as amended from time to time ceases to be valid and binding and in full
force and effect in all material respects; (x) any default by a counterparty
under any of the Material Project Agreements occurs (as defined in the Project
Indenture as in effect on the date of the Indenture) that would likely have a
material adverse effect on the Company, NE LP or NE LLC or the Holders of the
Bonds and such default is not cured within 180 days (or 360 days if the
applicable partnership has promptly commenced and is diligently using its best
efforts to cure such default); (xi) an "Event of Default" occurs defined in the
Project Indenture as in effect on the date of the Indenture) other than as a
result of the breach of an immaterial covenant; and (xii) Project Securities are
accelerated. If any Event of Default (other than bankruptcy or insolvency events

                                      A1-7


at default) occurs and is continuing, the Trustee or the Holders of at least 25%
in principal amount of the then outstanding Bonds may declare by written notice
all the Bonds to be due and payable immediately.

         Notwithstanding the foregoing, in the case of an Event of Default
arising from certain events of bankruptcy or insolvency, all outstanding Bonds
will become due and payable without further action or notice. Holders may not
enforce the Indenture or the Bonds except as provided in the Indenture. Subject
to certain limitations, Holders of a majority in principal amount of the then
outstanding Bonds may direct the Trustee in its exercise of any trust or power.
The Trustee may withhold from Holders of the Bonds notice of any continuing
Default or Event of Default (except a Default or Event of Default relating to
the payment of principal or interest) if it determines that withholding notice
is in their interest. The Holders of a majority in aggregate principal amount of
the Bonds then outstanding by written notice to the Trustee may on behalf of the
Holders of all of the Bonds waive any existing Default or Event of Default and
its consequences under the Indenture except a continuing Default or Event of
Default in the payment of interest on, or the principal of, the Bonds. The
Company is required to deliver to the Trustee annually a statement regarding
compliance with the Indenture, and the Company is required upon becoming aware
of any Default or Event of Default, to deliver to the Trustee a statement
specifying such Default or Event of Default.

         13.  TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its individual
or any other capacity, may make loans to, accept deposits from, and perform
services for the Company or its Affiliates, and may otherwise deal with the
Company or its Affiliates, as if it were not the Trustee.

         14. NO RECOURSE AGAINST OTHERS. No director, officer, employee,
incorporator, partner, member or stockholder of the Company, NE LP or NE LLC as
such shall have any liability for any Obligations of the Company under the Bonds
or the indenture or NE LP under the Note or the Bond Guaranty for any claim
based on, in respect of, or by reason of, such Obligations or their creation.
Each Holder by accepting a Bond waives and releases all such liability The
waiver and release are part of the consideration for issuance of the Bonds.

         15. AUTHENTICATION. This Bond shall not be valid until authenticated by
the manual signature of the Trustee or an authenticating agent.

         16. ABBREVIATIONS. Customary abbreviations may be used in the name of a

to Minors Act).

RESTRICTED DEFINITIVE BONDS. In addition to the rights provided to Holders of
Bonds under the Indenture, Holders of Restricted Global Bonds and Restricted
Definitive Bonds shall have all the rights set forth in the A/B Exchange
Registration Rights Agreement dated as of the date of the Indenture, between the
Company and the parties named on the signature pages thereof (the "Registration

Committee on Uniform Security Identification Procedures, the Company has caused
CUSIP numbers to be printed on the Bonds and the Trustee may use CUSIP numbers
in notices of redemption as a convenience to Holders. No representation is made
as to the accuracy of such numbers either as printed on the Bonds or as
contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

         Capitalized terms used herein shall have the meanings assigned to them
in the Indenture referred to below unless otherwise indicated.

         1. INTEREST. ESI Tractebel Acquisition Corp., a Delaware corporation
(the "Company"), promises to pay interest on the principal amount of this Bond
at 7.99% per annum from the date of issuance until maturity and shall pay the
Registration Default Damages, if any, payable pursuant to Section 5 of the
Registration Rights Agreement referred to below. The Company will pay interest
and Registration Default Damages semi-annually on June 30 and December 30 of
each year, or if any such day is not a Business Day, on the next succeeding
Business Day (each an "Interest Payment Date"). Interest on the Bonds will
accrue from the most recent date to which interest has been paid or, if no
interest has been paid, from the date of issuance; provided that if there is no
existing Default in the payment of interest, and if this Bond is authenticated
between a record date referred to on the face hereof and the next succeeding
Interest Payment Date, interest shall accrue from such next succeeding Interest
Payment Date; provided, further, that the first Interest Payment Date shall be
June 30, 1998. The Company shall pay interest (including post-petition interest
in any proceeding under any Bankruptcy Law) on overdue principal and premium, if
any, from time to time on demand at a rate that is 1% per annum in excess of the
rate then in effect; it shall pay interest (including post-petition interest in
any proceeding under any Bankruptcy Law) on overdue installments of interest and
Registration Default Damages (without regard to any applicable grace periods)
from time to time on demand at the same rate to the extent lawful. Interest will
be computed on the basis of a 360-day year of twelve 30-day months.

         Until this Regulation S Temporary Global Bond is exchanged for one or
more Regulation S Permanent Global Bonds, the Holder hereof shall not be
entitled to receive payments of interest hereon; until so exchanged in full,
this Regulation S Temporary Global Bond shall in all other respects be entitled
to the same benefits as other Bonds under the Indenture.

         2. METHOD OF PAYMENT. The Company will pay interest on the Bonds
(except defaulted interest) and Registration Default Damages to the Persons who
are registered Holders of Bonds at the close of business on the June 15 or
December 15 next preceding the Interest Payment Date, even if such Bonds are
canceled after such record date and on or before such Interest Payment Date,
except as provided in Section 2.12 of the Indenture with respect to defaulted
interest. The Bonds will be payable as to principal, premium and Registration
Default Damages, if any, and interest at the office or agency of the Paying
Agent maintained for such purpose within or without the City and State of New
York, or, at the option of the Company, payment of interest and Registration
Default Damages may be made by check mailed to the Holders at their addresses
set forth in the register of Holders, and provided that payment by wire transfer
of immediately available funds will be required with respect to principal of and
interest, premium and Registration Default Damages on, all Global Bonds and all
other Bonds the Holders of which shall have provided wire transfer instructions
to the Company or the Paying Agent. Such payment shall be in such coin or
currency of the United States of America as at the time of payment is legal
tender for payment of public and private debts.


                                      A2-3


         3. PAYING AGENT AND REGISTRAR. Initially, State Street Bank and Trust
Company, the Trustee under the Indenture, will act as Paying Agent and
Registrar. The Company may change any Paying Agent or Registrar without notice
to any Holder. The Company or NE LP may act as Registrar but shall not act as
Paying Agent.

         4. INDENTURE AND PLEDGE AGREEMENTS. The Company issued the Bonds under
an Indenture dated as of February 19, 1998 ("Indenture") among the Company, NE
LP and NE LLC and the Trustee. The terms of the Bonds include those stated in
the Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939, as amended (15 U.S. Code ss.ss. 77aaa-77bbbb). The Bonds
are subject to all such terms, and Holders are referred to the Indenture and
such Act for a statement of such terms. To the extent any provision of this Bond
conflicts with the express provisions of the Indenture, the provisions of the
Indenture shall govern and be controlling. The Bonds are secured obligations of
the Company limited to $220 million in aggregate principal amount, plus amounts,
if any, issued to pay Registration Default Damages on outstanding Bonds as set
forth in Paragraph 2 hereof. The Bonds are secured by a pledge of (a) the
perfected, first priority pledge by NE LP to the Trustee, for the benefit of the
Trustee and the Holders of the Bonds, (i) NE LP's 100% member interest in NE LLC
and (ii) NE LP's 98% limited partner interest in each of NEA and NJEA; (b) the
second priority pledge by NE LP to the Trustee, for the benefit of the Trustee
and the Holders of the Bond, of NE LP's one percent general partner interest in
each of NEA and NJEA; (c) the perfected, first priority pledge by NE LLC to the
Trustee, for the benefit of the Trustee and the Holders of the Bond, of NE LLC's
one percent limited partner interest in each of NEA and NJEA; (d) the perfected,
first priority pledge by the Company to the Trustee, for the benefit of the
Trustee and the Holders of the Bonds, of the Note evidencing the Bond Loan; and
(e) a perfected, first priority lien on the Accounts and all funds deposited
therein and all Permitted Investments credited thereto granted to the Collateral
Agent, for the benefit of the Collateral Agent, the Trustee and the Holders of
the Bonds, by NE LP and NE LLC pursuant to the Indenture. The Bonds are also
secured by (a) the perfected, first priority pledge by each of ESI Northeast
Energy GP, Inc., ESI Northeast Energy LP, Inc., Tractebel Associates Northeast
LP, Inc. and Tractebel Northeast Generation GP, Inc. (collectively, the "Sponsor
Affiliates") to the Trustee, as collateral agent (in such capacity, the
Collateral Agent") for the benefit of the Collateral Agent, the Trustee and the
Holders of the Bonds, of all of such Sponsor Affiliate's partner interests in NE
LP and (b) a perfected, first priority pledge by each owner of the Company to
the Collateral Agent, for the benefit of the Collateral Agent, the Trustee and
the Holders of the Bonds, of all of the outstanding Capital Stock of the Company
pursuant to the Sponsor Pledge Agreement referred to in the Indenture (together
with the Company and Partner Pledge Agreement, the "Pledge Agreement"). The
Pledge Agreements will secure the payment and performance when due of all of the
Obligations of the Company under the Indenture and the Bonds, and of NE LP's
obligations under the Note and the Bond Guaranty, as provided in the Indenture
and the Pledge Agreements.


                                      A2-4


         5. OPTIONAL REDEMPTION.

         The Company shall not have the option to redeem the Bonds prior to June
30, 2008. Thereafter, the Company at the direction of NE LP shall have the
option to redeem the Bonds, in whole or in part, upon not less than 30 nor more
than 60 days' notice, at the redemption prices (expressed as percentages of
principal amount) set forth below plus accrued and unpaid interest and
Registration Default Damages thereon to the date fixed for redemption, if
redeemed during the twelve-month period beginning on June 30 of the years
indicated below:

            Year                                                 Percentage
            ----                                                 ----------
            2008................................................ 101.844%
            2009................................................ 101.229%
            2010................................................ 100.615%
            2011 and thereafter................................. 100.000%

         6. MANDATORY REDEMPTION; EXTRAORDINARY MANDATORY REDEMPTION

         Except as set forth in this paragraph and in paragraph 7 below and
except for the payment of the principal of the Bonds in semiannual installments
to the Holders thereof, the Company shall not be required to make mandatory
redemption or sinking fund payments with respect to the Bonds. The Company shall
be required to redeem the Bonds, pro rata, at a redemption price equal to the
outstanding principal amount thereof plus accrued and unpaid interest and any
Registration Default Damages to the date fixed for redemption if (1) (a) an
event occurs which triggers the mandatory redemption or repurchase of any or all
of the Project Securities pursuant to the terms of the Project Indenture and (b)
any funds so required to be applied to such redemption or repurchase remain
after giving effect to such redemption or repurchase of Project Securities, and
such excess funds equal at least $2 million and are distributed to NE LP or NE
LLC or (2) a buyout or similar payment is made to a Partnership under any Power
Purchase Agreement and any such funds are distributed to NE LP or NE LLC in
accordance with the terms of the Project Indenture and terms of the Indenture,
provided that, in each such case, only such funds so distributed must be applied
to the extraordinary mandatory redemption.

         7. REPURCHASE AT OPTION OF HOLDER.

         Upon the occurrence of a Change of Control (which shall not occur if
Moody's and S&P confirm that the then existing ratings of the Bonds will not be
lowered as a result of any of the events that, in the absence of such confirmed
rating, would constitute a Change of Control), the Company shall offer to each
Holder to repurchase all or any part (equal to $100,000 or an integral multiple
of $1,000 in excess thereof) of such Holder's Bonds pursuant to the offer
described below (the "Change of Control Offer") at a purchase price in cash
equal to 101% of the aggregate principal amount thereof plus accrued and unpaid
interest and Registration Default Damages thereon, if any, to the date of
purchase (the "Change of Control Payment"). Within ten days following any Change
of Control, the Company shall mail a notice to each Holder describing the
transaction or transactions that constitute the Change of Control and offering
to repurchase Bonds on the date specified in such notice, which date shall be no
earlier than 30 days and no later than 60 days from the date such notice is
mailed (the "Change of Control Payment Date"), pursuant to the procedures
required by the Indenture and described in such notice. The Company shall comply
with the requirements of Rule 14e-1 under the Exchange Act and any other
securities laws and regulations thereunder to the extent such laws and
regulations are applicable in connection with the repurchase of the Bonds as a
result of a Change of Control.


                                      A2-5


         8. NOTICE OF REDEMPTION. Subject to the book entry system described in
the Indenture, if less than all of the Bonds are to be redeemed or purchased in
an offer to purchase at any time, the Trustee shall select the Bonds to be
redeemed or purchased among the Holders of the Bonds in compliance with the
requirements of the principal national securities exchange, if any, on which the
Bonds are listed or, if the Bonds are not so listed, on a pro rata basis, by lot
or in accordance with any other method the Trustee considers fair and
appropriate; provided that, except in the case of an extraordinary mandatory
redemption, no Bonds will be redeemed or purchased in part if the unredeemed
portion will be in an unauthorized denomination. In the event of partial
redemption by lot, the particular Bonds to be redeemed shall be selected, unless
otherwise provided herein, not less than 30 nor more than 60 days prior to the
redemption date by the Trustee from the outstanding Bonds not previously called
for redemption.

         The Trustee shall promptly notify the Company in writing of the Bonds
selected for redemption and, in the case of any Bond selected for partial
redemption, the principal amount thereof to be redeemed. Bonds and portions of
Bonds selected shall be in amounts of $100,000 or whole multiples of $1,000 in
excess thereof; except that if all of the Bonds of a Holder are to be redeemed,
the entire outstanding amount of Bonds held by such Holder, even if not a
multiple of $100,000 or a multiple of $1,000 in excess thereof, shall be
redeemed. Except as provided in the preceding sentence, provisions of this
Indenture that apply to Bonds called for redemption also apply to portions of
Bonds called for redemption.

         9. DENOMINATIONS, TRANSFER, EXCHANGE. The Bonds are in registered form
without coupons in denominations of $100,000 and integral multiples of $1,000 in
excess thereof. The transfer of Bonds may be registered and Bonds may be
exchanged as provided in the Indenture. The Registrar and the Trustee may
require a Holder, among other things, to furnish appropriate endorsements and
transfer documents and the Company may require a Holder to pay any taxes and
fees required by law or permitted by the Indenture. The Company need not
exchange or register the transfer of any Bond or portion of a Bond selected for
redemption, except for the unredeemed portion of any Bond being redeemed in
part. Also, the Company need not exchange or register the transfer of any Bonds
for a period of 15 days before a selection of Bonds to be redeemed or during the
period between a record date and the corresponding Interest Payment Date.

         This Regulation S Temporary Global Bond is exchangeable in whole or in
part for one or more Global Bonds only (i) on or after the termination of the
40-day restricted period (as defined in Regulation S) and (ii) upon presentation
of certificates (accompanied by an Opinion of Counsel, if applicable) required
by Article 2 of the Indenture. Upon exchange of this Regulation S Temporary
Global Bond for one or more Global Bonds, the Trustee shall cancel this
Regulation S Temporary Global Bond.

         10. PERSONS DEEMED OWNERS. The registered Holder of a Bond may be
treated as its owner for all purposes.

         11. AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions,
the Indenture, the Bond Guaranty, the other Financing Agreements or the Bonds
may be amended or supplemented with the consent of the Holders of at least a
majority in principal amount of the then outstanding Bonds voting as a single
class, and any existing default (other than a Default or Event of Default in the
payment of the principal of, premium, if any, or interest on or Registration
Default Damages with respect to the Bonds, except a payment default resulting
from acceleration that has been rescinded) or compliance with any provision of
the Indenture, the Bond Guaranty, the other Financing Agreements or the Bonds
may be waived with the consent of the Holders of a majority in principal amount
of the then outstanding Bonds voting as a single class. Without the consent of
any Holder of a Bond, the Indenture, the Bond Guaranty, the other Financing
Agreements or the Bonds may be amended or supplemented to cure any ambiguity,
defect or inconsistency; to provide for uncertificated Bonds in addition to or
in place of certificated Bonds or to alter the provisions of Article 2 of the
Indenture (including the related definitions) in a manner that does not
materially adversely affect any Holder; to provide for the assumption of the
Company's obligations to Holders of the Bonds in case of a merger or
consolidation; to make any change that would provide any additional rights or
benefits to the Holders of the Bonds or that does not adversely affect the legal
rights under the Indenture of any such Holder; or to comply with the
requirements of the SEC in order to effect or maintain the qualification of the
Indenture under the Trust Indenture Act.

         12. DEFAULTS AND REMEDIES. Events of Default shall occur, if among
other things: (i) the Company or NE LP as applicable, defaults in the payment
when due of principal of or premium, if any, on the Bonds or the Note when the
same becomes due and payable at maturity, upon redemption (including in
connection with an offer to purchase) or otherwise and such default continues
for a period of 15 days; (ii) the Company or NE LP as applicable, defaults in
the payment when due of interest on or Registration Default Damages, if any,
with respect to the Bonds or the Note and such default continues for a period of
15 days; (iii) the Company, NE LP or NE LLC fails to comply with any of the
provisions of Section 4.07, 4.09, 4.15 or 5.01 hereof; (iv) the Company, NE LP
or NE LLC fails to observe or perform any other covenant, representation,
warranty or other agreement in this Indenture, the Bonds or any of the
Collateral Documents to which it is a party for 60 days after notice to the
Company by the Trustee or the Holders of at least 25% in aggregate principal
amount of the Bonds then outstanding voting as a single class; (v) the Company,
NE LP or NE LLC defaults in the payment when due (after giving effect to any
applicable grace periods) of any principal of or premium, if any, or interest on
any Indebtedness (other than the Bonds or the Note) the principal amount of
which exceeds $3 million in the aggregate; (vi) a final judgment or final
judgments for the payment of money are entered by a court or courts of competent

undischarged judgments exceeds $3 million; (vii) Any of the material provisions


                                      A2-7


of the Collateral Documents shall be held in any judicial proceeding to be
unenforceable or invalid or shall cease for any reason to be in full force and
effect or any lien granted thereby or the priority thereof ceases or fails for
any reason to be in full force and effect (and such unenforceable provisions or
cessation or failure of a lien is not cured within 10 days after the Company, NE
LP or NE LLC has obtained knowledge thereof); (viii) certain events of
bankruptcy or insolvency with respect to the Company, NE LP or NE LLC occurs;
(ix) any limited partnership or limited liability company agreement of NE LP or
NE LLC as amended from time to time ceases to be valid and binding and in full
force and effect in all material respects; (x) any default by a counterparty
under any of the Material Project Agreements occurs (as defined in the Project
Indenture as in effect on the date of the Indenture) that would likely have a
material adverse effect on the Company, NE LP or NE LLC or the Holders of the
Bonds and such default is not cured within 180 days (or 360 days if the
applicable partnership has promptly commenced and is diligently using its best
efforts to cure such default); (xi) an "Event of Default" occurs defined in the
Project Indenture as in effect on the date of the Indenture) other than as a
result of the breach of an immaterial covenant; and (xii) Project Securities are
accelerated.. If any Event of Default (other than bankruptcy or insolvency
events at default) occurs and is continuing, the Trustee or the Holders of at
least 25% in principal amount of the then outstanding Bonds may declare by
written notice all the Bonds to be due and payable immediately. Notwithstanding
the foregoing, in the case of an Event of Default arising from certain events of
bankruptcy or insolvency, all outstanding Bonds will become due and payable
without further action or notice. Holders may not enforce the Indenture or the
Bonds except as provided in the Indenture. Subject to certain limitations,
Holders of a majority in principal amount of the then outstanding Bonds may
direct the Trustee in its exercise of any trust or power. The Trustee may
withhold from Holders of the Bonds notice of any continuing Default or Event of
Default (except a Default or Event of Default relating to the payment of
principal or interest) if it determines that withholding notice is in their
interest. The Holders of a majority in aggregate principal amount of the Bonds
then outstanding by written notice to the Trustee may on behalf of the Holders
of all of the Bonds waive any existing Default or Event of Default and its
consequences under the Indenture except a continuing Default or Event of Default
in the payment of interest on, or the principal of, the Bonds. The Company is
required to deliver to the Trustee annually a statement regarding compliance
with the Indenture, and the Company is required upon becoming aware of any
Default or Event of Default, to deliver to the Trustee a statement specifying
such Default or Event of Default.

         13. TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its individual or
any other capacity, may make loans to, accept deposits from, and perform
services for the Company or its Affiliates, and may otherwise deal with the
Company or its Affiliates, as if it were not the Trustee.

         14. NO RECOURSE AGAINST OTHERS. No director, officer, employee,
incorporator, partner, member or stockholder of the Company, NE LP or NE LLC as
such shall have any liability for any Obligations of the Company under the Bonds
or the indenture or NE LP under the Note or the Bond Guaranty for any claim
based on, in respect of, or by reason of, such Obligations or their creation.
Each Holder by accepting a Bond waives and releases all such liability The
waiver and release are part of the consideration for issuance of the Bonds.


                                      A2-8


         15. AUTHENTICATION. This Bond shall not be valid until authenticated by
the manual signature of the Trustee or an authenticating agent.

in notices of redemption as a convenience to Holders. No representation is made
as to the accuracy of such numbers either as printed on the Bonds or as

                               W I T N E S S E T H

         WHEREAS, the Company has heretofore executed and delivered to the
Trustee an indenture (the "Indenture"), dated as of February 19, 1998 providing
for the issuance of an aggregate principal amount of up to $220,000,000 of 7.99%
Bonds due 2011 (the "Bonds");

         WHEREAS, the Indenture provides that under certain circumstances the
Guaranteeing Entity shall execute and deliver to the Trustee a supplemental
indenture pursuant to which the Guaranteeing Entity shall unconditionally
guarantee all of the Company's Obligations under the Bonds and the Indenture on
the terms and conditions set forth herein (the "Bond Guarantee"); and

         WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee is
authorized to execute and deliver this Supplemental Indenture.

         NOW THEREFORE, in consideration of the foregoing and for other good and
valuable consideration, the receipt of which is hereby acknowledged, the
Guaranteeing Entity and the Trustee mutually covenant and agree for the equal
and ratable benefit of the Holders of the Bonds as follows:

         1. Capitalized Terms. Capitalized terms used herein without definition
shall have the meanings assigned to them in the Indenture.

         2. Agreement to Guarantee. The Guaranteeing Entity hereby agrees as
follows:

            (a) Along with the Bond Guarantor named in the Indenture, to jointly
                and severally Guarantee to each Holder of a Bond authenticated
                and delivered by the Trustee and to the Trustee and its
                successors and assigns, irrespective of the validity and
                enforceability of the Indenture, the Bonds or the obligations of
                the Company hereunder or thereunder, that:

                 (i) the principal of and interest on the Bonds will be promptly
                     paid in full when due, whether at maturity, by
                     acceleration, redemption or otherwise, and interest on the
                     overdue principal of and interest on the Bonds, if any, if
                     lawful, and all other obligations of the Company to the
                     Holders or the Trustee hereunder or thereunder will be
                     promptly paid in full or performed, all in accordance with
                     the terms hereof and thereof; and


                                      F-1


                 (ii) in case of any extension of time of payment or renewal of
                     any Bonds or any of such other obligations, that same will
                     be promptly paid in full when due or performed in
                     accordance with the terms of the extension or renewal,
                     whether at stated maturity, by acceleration or otherwise.
                     Failing payment when due of any amount so guaranteed or any
                     performance so guaranteed for whatever reason, the
                     Guarantors shall be jointly and severally obligated to pay
                     the same immediately.

            (b) The obligations hereunder shall be unconditional, irrespective
                of the validity, regularity or enforceability of the Bonds or
                the Indenture, the absence of any action to enforce the same,
                any waiver or consent by any Holder of the Bonds with respect to
                any provisions hereof or thereof, the recovery of any judgment
                against the Company, any action to enforce the same or any other
                circumstance which might otherwise constitute a legal or
                equitable discharge or defense of a guarantor.

            (c) The following is hereby waived: diligence presentment, demand of
                payment, filing of claims with a court in the event of
                insolvency or bankruptcy of the Company, any right to require a
                proceeding first against the Company, protest, notice and all
                demands whatsoever.

            (d) This Bond Guaranty shall not be discharged except by complete
                performance of the obligations contained in the Bonds and the
                Indenture.

            (e) If any Holder or the Trustee is required by any court or
                otherwise to return to the Company, the Guarantors, or any
                Custodian, Trustee, liquidator or other similar official acting
                in relation to either the Company or the Guarantors, any amount
                paid by either to the Trustee or such Holder, this Bond
                Guarantee, to the extent theretofore discharged, shall be
                reinstated in full force and effect.

            (f) The Guaranteeing Entity shall not be entitled to any right of
                subrogation in relation to the Holders in respect of any
                obligations guaranteed hereby until payment in full of all
                obligations guaranteed hereby.

            (g) As between the Guarantors, on the one hand, and the Holders and
                the Trustee, on the other hand, (x) the maturity of the
                obligations guaranteed hereby may be accelerated as provided in
                Article 6 of the Indenture for the purposes of this Bond
                Guaranty, notwithstanding any stay, injunction or other
                prohibition preventing such acceleration in respect of the
                obligations guaranteed hereby, and (y) in the event of any
                declaration of acceleration of such obligations as provided in
                Article 6 of the Indenture, such obligations (whether or not due
                and payable) shall forthwith become due and payable by the
                Guarantors for the purpose of this Bond Guaranty.


                                      F-2


                  (h)      The Guarantors shall have the right to seek
                           contribution from any non-paying Guarantor so long as
                           the exercise of such right does not impair the rights
                           of the Holders under the Guarantee.


                  (i)      Pursuant to Section 12.02 of the Indenture, after
                           giving effect to any maximum amount and any other
                           contingent and fixed liabilities that are relevant
                           under any applicable Bankruptcy or fraudulent
                           conveyance laws, and after giving effect to any
                           collections from, rights to receive contribution from
                           or payments made by or on behalf of any other
                           Guarantor in respect of the obligations of such other
                           Guarantor under Article 12 of the Indenture shall
                           result in the obligations of such Guarantor under its
                           Bond Guaranty not constituting a fraudulent transfer
                           or conveyance.

         3. EXECUTION AND DELIVERY. Each Guaranteeing Entity agrees that the
Bond Guaranty shall remain in full force and effect notwithstanding any failure
to endorse on each Bond a notation of such Bond Guaranty.

         4. Guaranteeing Entity May Consolidate, Etc. on Certain Terms.

             (a) The Guaranteeing Entity may not consolidate with or merge with
                 or into (whether or not such Guarantor is the surviving Person)
                 another corporation, Person or entity whether or not affiliated
                 with such Guarantor unless:

                 (i)  subject to Section 12.05 of the Indenture, the Person
                      formed by or surviving any such consolidation or merger
                      (if other than a Guarantor or the Company) unconditionally
                      assumes all the obligations of such Guarantor, pursuant to
                      a supplemental indenture in form and substance reasonably
                      satisfactory to the Trustee, under the Bonds, the
                      Indenture and the Bond Guaranty on the terms set forth
                      herein or therein; and

                 (ii) immediately after giving effect to such transaction, no
                      Default or Event of Default exists.

             (b) In case of any such consolidation, merger, sale or conveyance
                 and upon the assumption by the successor corporation, by
                 supplemental indenture, executed and delivered to the Trustee
                 and satisfactory in form to the Trustee, of the Bond Guaranty
                 endorsed upon the Bonds and the due and punctual performance of
                 all of the covenants and conditions of the Indenture to be
                 performed by the Guarantor, such successor corporation shall
                 succeed to and be substituted for the Guarantor with the same
                 effect as if it had been named herein as a Guarantor. Such
                 successor corporation thereupon may cause to be signed any or
                 all of the Bond Guarantees to be endorsed upon all of the Bonds
                 issuable hereunder which theretofore shall not have been signed
                 by the Company and delivered to the Trustee. All the Bond
                 Guarantees so issued shall in all respects have the same legal
                 rank and benefit under the Indenture as the Bond Guarantees
                 theretofore and thereafter issued in accordance with the terms
                 of the Indenture as though all of such Bond Guarantees had been
                 issued at the date of the execution hereof.


                                      F-3


             (c) Except as set forth in Articles 4 and 5 of the Indenture, and
                 notwithstanding clauses (a) and (b) above, nothing contained in
                 the Indenture or in any of the Bonds shall prevent any
                 consolidation or merger of a Guarantor with or into the Company
                 or another Guarantor, or shall prevent any sale or conveyance
                 of the property of a Guarantor as an entirety or substantially
                 as an entirety to the Company or another Guarantor.

         5. NO RECOURSE AGAINST OTHERS. No past, present or future director,
officer, employee, incorporator, stockholder or agent of the Guaranteeing
Entity, as such, shall have any liability for any obligations of the Company or
any Guaranteeing Entity under the Bonds, any Bond Guarantees, the Indenture or
this Supplemental Indenture or for any claim based on, in respect of, or by
reason of, such obligations or their creation. Each Holder of the Bonds by
accepting a Bond waives and releases all such liability. The waiver and release
are part of the consideration for issuance of the Bonds. Such waiver may not be
effective to waive liabilities under the federal securities laws and it is the
view of the Commission that such a waiver is against public policy.

         6. NEW YORK LAW TO GOVERN. THE INTERNAL LAW OF THE STATE OF NEW YORK
SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE BUT WITHOUT
GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT
THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

         7. COUNTERPARTS The parties may sign any number of copies of this
Supplemental Indenture. Each signed copy shall be an original, but all of them
together represent the same agreement.

         8. EFFECT OF HEADINGS. The Section headings herein are for convenience
only and shall not affect the construction hereof.

         9. THE TRUSTEE. The Trustee shall not be responsible in any manner
whatsoever for or in respect of the validity or sufficiency of this Supplemental
Indenture or for or in respect of the recitals contained herein, all of which
recitals are made solely by the Guaranteeing Entity and the Company.




                                      F-4




         IN WITNESS WHEREOF, the parties hereto have caused this Supplemental
Indenture to be duly executed and attested, all as of the date first above
written.
