regulation as a provider of thermal energy under applicable state laws and/or
regulations;

       (gg) As long as each of the Projects is a Qualifying Facility, none of

obligations of the Company, NE LP, NE LLC or the Partnerships by imposing liens
on the Collateral; (C) the Trustee's or the Collateral Agent's ownership of the
Projects; or (D) any other transaction contemplated by this Agreement: (i)

holding company" or a wholly or partially-owned, direct or indirect, subsidiary
of an "electric utility" or

                                       8

from the Company, at a purchase price of 7.99% of the principal amount thereof,
plus accrued interest, if any, from February 19, 1998 to the Time of Delivery
hereunder, the Bonds.

       3. Upon the authorization by the Company of the release of the Bonds, the
Purchaser proposes to offer the Bonds for sale upon the terms and conditions set
forth in this Agreement and the Offering Circular and the Purchaser makes the
representations, warranties and agreements set forth in Annex I to this
Agreement and hereby further represents and warrants to, and agrees with the
Company, the Bond Guarantor, the Sponsor Guarantors and the Partnerships that:

       (a) It will offer and sell the Bonds only to: (i) persons who it
reasonably believes are "qualified institutional buyers" ("QIBs") within the
meaning of Rule 144A under the Securities Act ("Rule 144A") in transactions
meeting the requirements of Rule 144A or (ii) through its affiliates, in
offshore transactions in reliance on Regulation S under the Securities Act
(purchasers of Bonds pursuant to clauses (a)(i) and (a)(ii) of this Section 3
are referred to collectively as the "Eligible Purchasers");

       (b) It is an Institutional Accredited Investor within the meaning of Rule

       4. (a) The Bonds to be purchased by the Purchaser hereunder will be
represented by one or more definitive global Bonds in book-entry form which will
be deposited by or on behalf of the Company with The Depositary Trust Company
("DTC") or its designated custodian. The Company will deliver the Bonds to the
Purchaser, for its account, against payment of the purchase price therefor by
wire transfer of Federal (same day) funds, by causing DTC to credit the Bonds to
the account of Goldman, Sachs & Co. at DTC. The time and date of such delivery
and payment shall be 9:30 a.m., New York City time, on February 19, 1998 or such
other time and date as the Purchaser and the Company may agree upon in writing.
Such time and date are herein called the "Time of Delivery." The Company will
cause the definitive global Bonds to be made available to the Purchaser for
checking at least twenty-four hours prior to the Time of Delivery (as defined
below) at the office of DTC or its designated custodian (the "Designated
Office"); and

       (b) The documents to be delivered at the Time of Delivery by or on behalf
of the parties hereto pursuant to Section 7 hereof, including the cross-receipt

of Latham & Watkins at 885 Third Avenue, Suite 1000, New York, New York 10022
(the "Closing Location"), and the Bonds will be delivered at the Designated
Office, all at the Time of Delivery. A meeting will be held at the Closing
Location at 3:00 p.m., New York City time, on the New York Business Day next
preceding the Time of Delivery, at which meeting the final drafts of the
documents to be delivered pursuant to the preceding sentence will be available
for review by the parties hereto. For the purposes of this Section 4, "New York
Business Day" shall mean each Monday, Tuesday, Wednesday, Thursday and Friday
which is not a day on which banking institutions in New York are generally
authorized or obligated by law or executive order to close.

       5. Each of the Company and the Bond Guarantor, jointly and severally,

service of process in any jurisdiction;

       (c) To furnish the Purchaser with as many copies of the Offering Circular

Exchange or the expiration of nine months after the date of the Offering
Circular, any event shall have occurred as a result of which the Offering
Circular as then amended or supplemented would include an untrue statement of a
material fact or omit to state any material fact necessary in order to make the
statements therein, in the light of the circumstances under which they were made
when such Offering Circular is delivered, not misleading, or, if for any other
reason it shall be necessary or in the opinion of the Company and the Bond
Guarantor desirable during such same period to amend or supplement the Offering
Circular, to notify you and upon your request to prepare and furnish without

GAAP), including a "Management's Discussion and Analysis of Financial Condition
and Results of Operations" and, with respect to the annual information only, a
report thereon by the certified independent accountants of the Company and (ii)

the Company were required to file such reports, in each case, within the time
periods specified in the Commission's rules and regulations. In addition,
following consummation of the Exchange Offer, whether or not required by the
rules and regulations of the Commission, the Company shall file a copy of all
such information and reports with the Commission for public availability within

Company is subject to the reporting requirements of Section 13 or Section 15(d)
of the Exchange Act, the Company will be required to file with the Commission

Bond Guarantor is listed; and (ii) such additional information concerning the
business and financial condition of the Company, the Bond Guarantor, the
Partnerships and their respective subsidiaries, as you may from time to time

the extent the accounts of the Company and its subsidiaries are consolidated in
reports furnished to the Holders of the Bonds generally or to the Commission);

       (j) During the period of two years after the Time of Delivery, neither
the Company nor the Bond Guarantor will, nor will it permit any of its

the Projects ceasing to be a Qualifying Facility; (ii) the Company, the Bond
Guarantor or the Partnerships becoming: (A) subject to regulation under Part II
or the Federal Power Act, except for Sections 202(c), 210, 211, 212, 213, 214

292) or (D) subject to state regulation as a provider of thermal energy under
applicable state laws and/or regulations; or (iii) the Purchaser, the Trustee or
the Collateral Agent becoming (A) "primarily engaged in the generation or sale

Holding Company Act, or (C) subject to regulation under applicable state laws

Indenture;

       provided, however that the obligations of the Company and the Bond
Guarantor to comply with clauses (m) and (n) of this Section 5 shall cease upon
the execution and delivery of the Indenture by all parties thereto and the
consummation of the transactions contemplated therein.

       6. Each of the Company and the Guarantors, jointly and severally,
covenants and agrees with the Purchaser that it will pay or cause to be paid the
following: (i) the fees, disbursements and expenses of the Company's and the

(iv) any fees charged by securities rating services for rating the Bonds; (v)
the cost of preparing the global Bonds and the Guarantees; (vi) the fees and

with the Indenture and the Bonds and the Guarantees; (viii) any cost incurred in
connection with the designation of the Bonds for trading in PORTAL and (ix) all
other costs and expenses incident to the performance of its obligations

including the fees of its counsel, transfer taxes on resale of any of the Bonds
by the Purchaser, and any advertising expenses connected with any offers it may
make.

       7. Conditions Precedent to the obligations of the Purchaser:

affecting the general affairs, management, financial position, shareholders'
equity or partners' equity interests, as applicable, or results of operations of
it and its subsidiaries, otherwise than as set forth or contemplated in the
Offering Circular, the effect of which, in any such case described in Clause (i)
or (ii), is in the judgment of the Purchaser so material and adverse as to make
it impracticable or inadvisable to proceed with the public offering or the
delivery of the Bonds on the terms and in the manner contemplated in this
Agreement and in the Offering Circular;

       (g) On or after the date hereof (A) (i) the ratings of the Bonds shall be

       (j) Each of the Company and the Guarantors shall have furnished or caused

the performance by each of the Company

                                       13


and the Guarantors of all of their respective obligations hereunder to be
performed at or prior to such Time of Delivery, as to the matters set forth in
subsections (a), (f) and (g) of this Section and as to such other matters as you
may reasonably request.

       8. (a) The Company and each of the Guarantors, collectively referred to
herein as the "Indemnifying Parties" and each individually as the "Indemnifying
Party") will, jointly and severally, indemnify and hold harmless the Purchaser
against any losses, claims, damages or liabilities, joint or several, to which
such Purchaser may become subject, under the Securities Act or otherwise,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon an untrue statement or alleged untrue
statement of a material fact contained in the Offering Circular, or any
amendment or supplement thereto, or arise out of or are based upon the omission
or alleged omission to state therein a material fact necessary to make the
statements therein not misleading, and will reimburse the Purchaser for any
legal or other expenses reasonably incurred by the Purchaser in connection with
investigating or defending any such action or claim as such expenses are
incurred; provided, however, that the Company or the Guarantors shall not be
liable in any such case to the extent that any such loss, claim, damage or
liability arises out of or is based upon an untrue statement or alleged untrue
statement or omission or alleged omission made in any Preliminary Offering
Circular or the Offering Circular or any such amendment or supplement in
reliance upon and in conformity with written information furnished to the
Company or the Guarantors by the Purchaser expressly for use therein.


       (b) The Purchaser will indemnify and hold harmless the Indemnifying
Parties against any losses, claims, damages or liabilities to which such
Indemnifying Parties may become subject, under the Securities Act or otherwise,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon an untrue statement or alleged untrue
statement of a material fact contained in any Preliminary Offering Circular or
the Offering Circular, or any amendment or supplement thereto, or arise out of
or are based upon the omission or alleged omission to state therein a material
fact or necessary to make the statements therein not misleading, in each case to
the extent, but only to the extent, that such untrue statement or alleged untrue
statement or omission or alleged omission was made in any Preliminary Offering
Circular or the Offering Circular or any such amendment or supplement in
reliance upon and in conformity with written information furnished to the
Indemnifying Parties by the Purchaser expressly for use therein; and will
reimburse the Indemnifying Parties for any legal or other expenses reasonably
incurred by such Indemnifying Parties in connection with investigating or
defending any such action or claim as such expenses are incurred.

       (c) Promptly after receipt by an indemnified party under subsection (a)
or (b) above of notice of the commencement of any action, such indemnified party
shall, if a claim in respect thereof is to be made against the indemnifying
party under such subsection, notify the indemnifying party in writing of the
commencement thereof; but the omission so to notify the indemnifying party shall
not relieve it from any liability which it may have to any indemnified party
otherwise than under such subsection. In case any such action shall be brought
against any indemnified party and it shall notify the indemnifying party of the
commencement thereof, the indemnifying party shall be entitled to participate
therein and, to the extent that it shall wish, jointly with any other
indemnifying party similarly notified, to assume the defense thereof, with
counsel satisfactory to such indemnified party (who shall not, except with the
consent of the indemnified party, be counsel to the indemnifying party), and,
after notice from the indemnifying party to such indemnified party of its
election so to assume the defense thereof, the indemnifying party shall not be
liable to such indemnified party under such subsection for any legal expenses of
other counsel or any other expenses, in each case subsequently incurred by such
indemnified party, in connection with the defense thereof other than reasonable
costs of investigation. No indemnifying party shall, without the written consent
of the indemnified party, effect the settlement or compromise of, or consent to
the entry of any judgment with respect to, any pending or threatened action or
claim in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified party is an actual or potential party
to such action or claim) unless such

                                       14


settlement, compromise or judgment (i) includes an unconditional release of the
indemnified party from all liability arising out of such action or claim and
(ii) does not include a statement as to, or an admission of, fault, culpability
or a failure to act, by or on behalf of any indemnified party.

       (d) If the indemnification provided for in this Section 8 is unavailable
to or insufficient to hold harmless an indemnified party under subsection (a) or
(b) above in respect of any losses, claims, damages or liabilities (or actions
in respect thereof) referred to therein, then each indemnifying party shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages or liabilities (or actions in respect thereof)
in such proportion as is appropriate to reflect the relative benefits received
by the Indemnifying Parties on the one hand and the Purchaser on the other from
the offering of the Bonds. If, however, the allocation provided by the
immediately preceding sentence is not permitted by applicable law or if the
indemnified party failed to give the notice required under subsection (c) above,
then each indemnifying party shall contribute to such amount paid or payable by
such indemnified party in such proportion as is appropriate to reflect not only
such relative benefits but also the relative fault of the Indemnifying Parties
on the one hand and the Purchaser on the other in connection with the statements
or omissions which resulted in such losses, claims, damages or liabilities (or
actions in respect thereof), as well as any other relevant equitable
considerations. The relative benefits received by the Indemnifying Parties on
the one hand and the Purchaser on the other shall be deemed to be in the same
proportion as the total net proceeds from the offering (before deducting
expenses) received by the Indemnifying Parties bear to the total underwriting
discounts and commissions received by the Purchaser, in each case as set forth
in the Offering Circular. The relative fault shall be determined by reference
to, among other things, whether the untrue or alleged untrue statement of a
material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Indemnifying Parties on the one hand or
the Purchaser on the other and the parties' relative intent, knowledge, access
to information and opportunity to correct or prevent such statement or omission.
The Indemnifying Parties and the Purchaser agree that it would not be just and
equitable if contribution pursuant to this subsection (d) were determined by pro
rata allocation or by any other method of allocation which does not take account
of the equitable considerations referred to above in this subsection (d). The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages or liabilities (or actions in respect thereof) referred to above
in this subsection (d) shall be deemed to include any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim. Notwithstanding the provisions of this
subsection (d), the Purchaser shall not be required to contribute any amount in
excess of the amount by which the total price at which the Bonds were offered to
investors exceeds the amount of any damages which the Purchaser has otherwise
been required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission.

       (e) The obligations of the Indemnifying Parties under this Section 8
shall be in addition to any liability which the Indemnifying Parties may
otherwise have and shall extend, upon the same terms and conditions, to each
person, if any, who controls the Purchaser within the meaning of the Securities
Act; and the obligations of the Purchaser under this Section 8 shall be in
addition to any liability which the Purchaser may otherwise have and shall
extend, upon the same terms and conditions, to each officer and director of the
Indemnifying Parties and to each person, if any, who controls any Indemnifying
Parties within the meaning of the Securities Act.

       9. The respective indemnities, agreements, representations, warranties
and other statements of the Company, the Guarantors and the Purchaser, as set
forth in this Agreement or made by them, respectively, pursuant to this
Agreement, shall remain in full force and effect, regardless of any
investigation (or any statement as to the results thereof) made by the Purchaser
or any controlling person of the Purchaser, or any of the Company or the
Guarantors, or any officer or director or controlling person thereof, and shall
survive delivery of and payment for the Bonds.

                                       15


       10. If for any other reason, the Bonds are not delivered by or on behalf
of the Company as provided herein, the Company and each of the Guarantors,
jointly and severally, will reimburse you for all out-of-pocket expenses
approved in writing by you, including fees and disbursements of counsel,
reasonably incurred by you in making preparations for the purchase, sale and

         Representations and Warranties of the Purchaser referred to in
Section 3:

         (1) The Bonds have not been and will not be, other than as provided in
the Registration Rights Agreement, registered under the Securities Act and may
not be offered or sold within the United States or to, or for the account or
benefit of, U.S. persons except in accordance with Regulation S under the
Securities Act or pursuant to an exemption from the registration requirements of
the Securities Act. The Purchaser represents that it has offered and sold the
Bonds and will offer and sell the Bonds (i) as part of its distribution at any
time and (ii) otherwise until 40 days after the later of the commencement of the
offering and the Time of Delivery, only in accordance with Rule 903 of
Regulation S or the Rule 144A under the Securities Act. Accordingly, the
Purchaser agrees that neither it, its affiliates nor any persons acting on its
behalf has engaged or will engage in any directed selling efforts with respect
to the Bonds, and it and they have complied and will comply with the offering
restrictions requirement of Regulation S. The Purchaser agrees that, at or prior
to confirmation of sale of Bonds (other than a sale pursuant to Rule 144A) it
will have sent to each distributor, dealer or person receiving a selling
concession, fee or other remuneration that purchases Bonds from it during the
restricted period a confirmation or notice to substantially the following
effect:

                 "The Bonds covered hereby have not been registered under the
         U.S. Securities Act of 1933 (the "Securities Act") and may not be
         offered and sold within the United States or to, or for the account or
         benefit of, U.S. persons (i) as part of their distribution at any time
         or (ii) otherwise until 40 days after the later of the commencement of
         the offering and the closing date, except in either case in accordance
         with Regulation S (or Rule 144A if available) under the Securities Act.
         Terms used above have the meaning given to them by Regulation S."

Terms used in this paragraph have the meanings given to them by Regulation S.

         The Purchaser further agrees that it has not entered and will not enter
into any contractual arrangement with respect to the distribution or delivery of
the Bonds except with its affiliates or with the prior written consent of the
Company.

         In addition,

                 (A) except to the extent permitted under U.S. Treas. Reg. ss.
         1.163-5(C)(2)(i)(D) (the "D Rules"), (i) the Purchaser agrees that it
         has not offered or sold, and during the restricted period will not
         offer or sell, Bonds in bearer form to a person who is within the
         United States or its possessions or to a U.S. person, and (ii) it has
         not delivered and will not deliver within the United States or its
         possessions definitive Bonds in bearer form that are sold during the
         restricted period;

                 (B) the Purchaser represents and agrees that it has, and
         throughout the restricted period will have, in effect procedures
         reasonably designed to ensure that its employees or agents who are
         directly engaged in selling Bonds in bearer form are aware that such
         Bonds may not be offered or sold during the restricted period to a
         person who is within the United States or its possessions or to a
         United States person, except as permitted by the D Rules;

                 (C) if it is a United States person, the Purchaser represents
         that it is acquiring the Bonds in bearer form for purposes of resale in
         connection with their original issuance and if it retains Bonds in

                                      A-4


         bearer form for its own account, it will only do so in accordance with
         the requirements of U.S. Treas. Reg. ss. 1.163-5(c)(2)(i)(D)(6); and

                 (D) with respect to each affiliate that acquires from it Bonds
         in bearer form for the purpose of offering or selling such Bonds during
         the restricted period, the Purchaser either (i) repeats and confirms
         the representations and agreements contained in clauses (A), (B) and
         (C) on its behalf or (ii) agrees that it will obtain from such
         affiliate for the Company's benefit the representations and agreements
         contained in clauses (A), (B) and (C).

Terms used in this paragraph have the meanings given to them by the United
States Internal Revenue Code and regulations thereunder, including the D Rules.

         (2) Notwithstanding the foregoing, Bonds in registered form may be
offered, sold and delivered by the Purchaser in the United States and to U.S.
persons pursuant to Section 3 of this Agreement without delivery of the written
statement required by paragraph (1) above.

         (3) The Purchaser further represents and agrees, on behalf of itself
and its affiliates, that (i) it has not offered or sold and prior to the date
six months after the date of issue of the Bonds will not offer or sell any Bonds
to persons in the United Kingdom except to persons whose ordinary activities
involve them in acquiring, holding, managing or disposing of investments (as
principal or agent) for the purposes of their businesses or otherwise in
circumstances which have not resulted and will not result in an offer to the
public in the United Kingdom within the meaning of the Public Offers of
Securities Regulations 1995, (b) it has complied, and will comply, with all
applicable provisions of the Financial Services Act of 1986 of Great Britain
with respect to anything done by it in relation to the Bonds in, from or
otherwise involving the United Kingdom, and (C) it has only issued or passed on
and will only issue or pass on in the United Kingdom any document received by it
in connection with the issuance of the Bonds to a person who is of a kind
described in Article 11(3) of the Financial Services Act 1986 (Investment
Advertisements) (Exemptions) Order 1996 of Great Britain or is a person to whom
the document may otherwise lawfully be issued or passed on.

         (4) The Purchaser agrees that it will not offer, sell or deliver any of
the Bonds in any jurisdiction outside the United States except under
circumstances that will result in compliance with the applicable laws thereof,
and that it will take at its own expense whatever action is required to permit
its purchase and resale of the Bonds in such jurisdictions. The Purchaser
understands that no action has been taken to permit a public offering in any
jurisdiction outside the United States where action would be required for such
purpose. The Purchaser agrees not to cause any advertisement of the Bonds to be
published in any newspaper or periodical or posted in any public place and not
to issue any circular relating to the Bonds, except in any such case with
Goldman, Sachs & Co.'s express written consent and then only at its own risk and
expense.
