        Section 2.01.   Conveyance of RRB Property. In consideration of the
                        --------------------------
Issuer's delivery to or upon the order of the Seller of $____________, the
Seller does hereby irrevocably sell, transfer, assign, set over and otherwise

forth herein, all right, title and interest of the Seller in and to the RRB
Property (such sale, transfer, assignment, setting over and conveyance of the

assignment of all revenues, collections, claims, payments, money or proceeds of

conveyance is hereby expressly stated to be a sale and, pursuant to RSA 369-B:6,
V, shall be treated as an absolute transfer of all of the Seller's right, title
and interest in (as in a true sale), and not as a pledge or other financing of,
the RRB Property. If such sale, transfer, assignment, setting over and

as provided in RSA 369-B:6, V, then such sale, transfer, assignment, setting
over and conveyance shall be treated as the creation of a security interest in

transferred all of its rights in the RRB Property to the Issuer, the Seller
hereby grants to the Issuer a security interest in the RRB Property (including,
to the fullest extent permitted by the Statute, all revenues, collections,
claims, payments, money or proceeds of or arising from the RRB Charge pursuant
to the Finance Order) to secure a payment obligation incurred by the Seller in
respect of the amount paid by the Issuer to the Seller pursuant to this

setting over and conveyance of the RRB Property includes the right to use the
Seller's computer software system to access and create copies of all books and
records related to the RRB Property.

classification of the Bonds as debt.

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

                       -----

Property from the Seller to the Issuer and that no interest in, or title to, the

the Seller to any Person other than the Issuer. On the Closing Date, immediately
upon the sale hereunder, the Seller has transferred, sold and conveyed the

                                      -6-

<PAGE>

RRB Property to the Issuer, free and clear of all Liens (including the Lien
of the Seller's first mortgage indenture but excluding any Lien created pursuant
to RSA 369-B:7, VIII and any Lien that may be granted under the Basic
Documents), and pursuant to RSA 369-B:6, V such transfer shall be treated as an
absolute transfer of all of the Seller's right, title and interest (as in a true
sale), and not as a pledge or other financing of, the RRB Property.

          (b)  Transfer Filings. On the Closing Date, immediately upon the sale
               ----------------
hereunder, the RRB Property has been validly transferred and sold to the Issuer,
the Issuer shall own all such RRB Property free and clear of all Liens
(including the Lien of the Seller's first mortgage indenture but excluding any
Lien created pursuant to RSA 369-B:7, VIII and any Lien that may be granted
under the Basic Documents) and all filings to be made by the Seller (including
filings with the NHPUC under the Statute) necessary in any jurisdiction to give
the Issuer a valid first priority perfected ownership interest and to grant to
the Trustee a first priority perfected security interest (subject to any Lien
created pursuant to RSA 369-B:7, VIII and any Lien that may be granted under the
Basic Documents) in the RRB Property have been made. No further action is
required to maintain the Issuer's first priority perfected ownership interest or
the Trustee's first priority perfected security interest (subject to any Lien
created pursuant to RSA 369-B:7, VIII and any Lien that may be granted under the
Basic Documents). Filings have also been made to the extent required by
applicable law in any jurisdiction to perfect the Back-Up Security Interest
granted by the Seller to the Issuer (subject to any Lien created pursuant to RSA

          (c)  Finance Order and Issuance Advice Letter; Other Approvals. On the
               ---------------------------------------------------------
Closing Date, under the laws of the State of New Hampshire and the United States
in effect on the Closing Date, (i) the Finance Order pursuant to which the RRB
Property has been created is in full force and effect; (ii) the Bondholders are
entitled to the protections of the Statute and, accordingly, the Finance Order
is not revocable by the Commission; (iii) the State of New Hampshire may neither
limit nor alter the RRB Charge, RRB Property, the Finance Order and all rights
thereunder, in a manner that would substantially impair the rights of
Bondholders, absent a demonstration that an impairment is narrowly-tailored and
is necessary to advance an important public interest, such as responding to a
"great public calamity," until the Bonds, together with accrued interest, are
fully met and discharged; provided that the State of New Hampshire is not
precluded from such limitation or alteration if and when adequate provision is
made by law for the protection of the Issuer, the Bondholders and the Trustee;
(iv) except for periodic adjustments to the RRB Charge required under the
Statute, the NHPUC does not have authority, either by rescinding, altering or
amending the Finance Order or otherwise, to revalue or revise for ratemaking
purposes the stranded costs or the costs of providing, recovering, financing or
refinancing the stranded costs, to determine that the RRB Charge is unjust or
unreasonable or in any way to reduce or impair the value of RRB Property either
directly or indirectly by taking the RRB Charge into account when setting other
rates for the Seller; nor are the amount of revenues arising with respect
thereto subject to reduction, impairment, postponement or termination; (v) the
process by which the Finance Order was adopted and approved, and the Finance
Order and Issuance Advice

                                      -7-

(vi) the Issuance Advice Letter has been filed in accordance with the Finance
Order; (vii) no other approval, authorization, consent, order or other action
of, or filing with, any court, Federal or state regulatory body, administrative
agency or other governmental instrumentality is required in connection with the
creation or sale of the RRB Property, except those that have been obtained or
made and post closing filings required in connection therewith and those that
the Seller, in its capacity as Servicer under the Servicing Agreement, is
required to make in the future pursuant to the Servicing Agreement; and (viii)
the State of New Hampshire, in the exercise of its executive or legislative
powers, may not repeal or amend the Statute or the Finance Order, or take any
action in contravention of the pledge by the State of New Hampshire in RSA
369-B:6, II, without paying just compensation to the Bondholders, as determined
by a court of competent jurisdiction, if this action would constitute a
permanent appropriation of a substantial property interest of Bondholders in the
RRB Property and deprive the Bondholders of their reasonable expectations
arising from their investments in the Bonds.


          (d)  Assumptions. On the Closing Date, based upon the information
               -----------
available to the Seller on the Closing Date, the assumptions used in calculating
the initial RRB Charge are reasonable and are made in good faith.
Notwithstanding the foregoing, the Seller makes no representation or warranty
that the assumptions used in calculating such RRB Charge will in fact be
realized.

          (e)  Creation of RRB Property. Upon the effectiveness of the Finance
               ------------------------
Order and the Issuance Advice Letter: (i) all of the RRB Property constitutes an
existing property right; (ii) the RRB Property includes the right, title and
interest in and to all revenues, collections, claims, payments, money, or
proceeds of or arising from the RRB Charge, as adjusted from time to time
pursuant to the Finance Order, and all rights to obtain adjustments to the RRB
Charge pursuant to the Finance Order; and (iii) subject to the cap on the
Seller's "stranded cost recovery charge" set forth in the Statute and the
Finance Order, the owner of the RRB Property is legally entitled to collect
payments in respect of the RRB Charge in the aggregate sufficient to pay the
interest on and principal of the Bonds, to pay the fees and expenses of
servicing the Bonds, to replenish the Capital Subaccount to the Required Capital
Level and to fund the Overcollateralization Subaccount to the Required
Overcollateralization Level, to fund the Interest Reserve Subaccount to the
Required Interest Reserve Level and to enforce all other material rights
conferred in the Finance Order and the Statute until the earlier of the eighth
anniversary of the issuance of the Bonds and the date on which the Bonds are
paid in full. Notwithstanding the foregoing, the Seller makes no representation
or warranty that any amounts actually collected in respect of the RRB Charge
will in fact be sufficient to meet payment obligations with respect to the Bonds
(other than as provided in the Finance Order with respect to other components of
the "stranded cost recovery charge" (as defined in the Statute)).

          (f)  Prospectus. As of the date hereof, the information describing the
               ----------

Notwithstanding any other provisions of this Agreement, the Seller will not be
in breach of any representation or warranty as a result of a change in law by
means of a legislative enactment or constitutional amendment or (if such means

representation or warranty that any amounts actually collected in respect of the

fact be realized nor shall the Seller be obligated to reduce, or accept a
reduction of, any rates or charges to which it would otherwise be entitled in
respect of services rendered or to be rendered to customers in order to permit
the payment of the RRB Charge (other than as provided in the Finance Order with
respect to other components of the "stranded cost recovery charge" (as defined
in the Statute)).

rights and franchises as a corporation under the laws of the jurisdiction of its
organization and (b) will obtain and preserve its qualification to do business,
in each case to the extent that in each such jurisdiction such existence or

other Basic Documents to which the Seller is

                                      -9-

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

                 (a)    So long as any of the Bonds are outstanding, the Seller
shall treat the Bonds as debt of the Issuer and not of the Seller, except for
financial accounting or tax reporting purposes.

                 (b)    So long as any of the Bonds are outstanding, the Seller
shall indicate in its financial statements that it is not the owner of the RRB
Property and that the assets of the Issuer are not available to pay creditors of
the Seller or any of its Affiliates (other than the Issuer).

                 (c)    So long as any of the Bonds are outstanding, the Seller
shall disclose the effects of all transactions between the Seller and the Issuer
in accordance with generally accepted accounting principles.

                 (d)    So long as any of the Bonds are outstanding, the Seller
shall not own or purchase any Bonds.

                 (e)    The Seller agrees that, upon the sale by the Seller of
the RRB Property to the Issuer pursuant to this Agreement, (i) to the fullest
extent permitted by law, including the Statute and applicable NHPUC Regulations,
the Issuer shall have all of the rights originally held by the Seller with
respect to the RRB Property, including the right (subject to the terms of the
Servicing Agreement) to exercise any and all rights and remedies to collect any
amounts payable by any customer or third party supplier in respect of the RRB
Property, notwithstanding any objection or direction to the contrary by the
Seller and (ii) any payment by any customer or third party supplier to the
Issuer shall discharge such customer's or third party supplier's obligations in
respect of the RRB Property to the extent of such payment, notwithstanding any
objection or direction to the contrary by the Seller.

                 (f)    So long as any of the Bonds are outstanding, (i)(A) the
Seller shall affirmatively certify and confirm that it has sold the RRB Property
to the Issuer (other than for financial accounting or tax reporting purposes),
and (B) the Seller shall not make any statement or reference in respect of the
RRB Property that is inconsistent with the ownership thereof by the Issuer
(other than for financial accounting or tax reporting purposes), and (ii) the
Seller shall not take any action in respect of the RRB Property except solely in
its capacity as the Servicer thereof pursuant to the Servicing Agreement or as
otherwise contemplated by the Basic Documents.

         Section 4.07.  Protection of Title. The Seller shall execute and file
                        -------------------
such filings, including filings with the NHPUC pursuant to the Statute and
Uniform Commercial Code filings, and cause to be executed and filed such
filings, all in such manner and in such places as may be required by law fully
to preserve, maintain and protect the ownership or security interest of the
Issuer and the Trustee in the RRB Property and the Back-Up Security Interest,
including all filings required under the Statute and the applicable Uniform
Commercial Code relating to the transfer of the ownership or security interest
in the RRB Property by the Seller to the Issuer and the granting of a security
interest in the RRB Property by the Issuer to the Trustee and the Back-Up
Security Interest and the

                                      -10-

<PAGE>

continued perfection of such ownership or security interest. The Seller shall
deliver (or cause to be delivered) to the Issuer and the Trustee file-stamped
copies of, or filing receipts for, any document filed as provided above, as soon
as available following such filing. The Seller shall institute any action or
proceeding necessary to compel performance by the NHPUC or the State of New
Hampshire of any of their obligations or duties under the Statute or the Finance
Order, and the Seller agrees to take such legal or administrative actions,
including defending against or instituting and pursuing legal actions and
appearing or testifying at hearings or similar proceedings, as may be reasonably
necessary (i) to protect the Issuer, the Bondholders, the Trustee, the State of
New Hampshire, the State Treasurer, agencies of the State of New Hampshire and
any of their respective affiliates, officials, officers, directors, employees,
consultants, counsel and agents from claims, state actions or other actions or
proceedings of third parties which, if successfully pursued, would result in a
breach of any representation set forth in Article III or (ii) to block or
overturn any attempts to cause a repeal of, modification of or supplement to the
Statute, the Finance Order, any Advice Letter (as defined in the Indenture), the
Settlement Agreement (as defined in the Finance Order) (to the extent it
adversely affects the rights of Bondholders or the validity or value of the RRB
Property) or the rights of Bondholders by executive action, legislative
enactment or constitutional amendment that would be adverse to the Issuer, the
Trustee or the Bondholders. If the Servicer performs its obligations under
Section 5.02(d) of the Servicing Agreement in all respects, such performance
shall be deemed to constitute performance of the Seller's obligations pursuant
to clause (ii) of the immediately preceding sentence. In such event, the Seller
agrees to assist the Servicer as reasonably necessary to perform its obligations
under Section 5.02(d) of the Servicing Agreement in all respects. The costs of
any such actions or proceedings shall be payable from RRB Charge Collections as
an Operating Expense in accordance with the priorities set forth in Section
8.02(d) of the Indenture. The Seller's obligations pursuant to this Section 4.07
shall survive and continue notwithstanding the fact that the payment of
Operating Expenses pursuant to Section 8.02(d) of the Indenture may be delayed
(it being understood that the Seller may be required to advance its own funds to
satisfy its obligations hereunder).

         Section 4.08.  Nonpetition Covenants.  Notwithstanding any prior
                        ---------------------
termination of this Agreement or the Indenture, but subject to the NHPUC's right
to order the sequestration and payment of revenues arising with respect to the
RRB Property notwithstanding any bankruptcy, reorganization or other insolvency
proceedings with respect to the Seller pursuant to RSA 369-B:7, V or RSA
369-B:7, VIII, the Seller shall not, prior to the date which is one year and one
day after the termination of the Indenture, petition or otherwise invoke or
cause the Issuer to invoke the process of any court or government authority for
the purpose of commencing or sustaining a case against the Issuer under any
Federal or state bankruptcy, insolvency or similar law, appointing a receiver,
liquidator, assignee, trustee, custodian, sequestrator or other similar official
of the Issuer or any substantial part of the property of the Issuer, or ordering
the winding up or liquidation of the affairs of the Issuer.

         Section 4.09.  Taxes.
                        -----

                 (a) So long as any of the Bonds are outstanding, the Seller
shall, and shall cause each of its subsidiaries to, pay all material taxes,
assessments and

                                      -11-

<PAGE>

governmental charges imposed upon it or any of its properties or assets or with
respect to any of its franchises, business, income or property before any
penalty accrues thereon if the failure to pay any such taxes, assessments and
governmental charges would, after any applicable grace periods, notices or other
similar requirements, result in a lien on the RRB Property; provided that no
such tax need be paid if the Seller or one of its subsidiaries is contesting the
same in good faith by appropriate proceedings promptly instituted and diligently
conducted and if the Seller or such subsidiary has established appropriate
reserves as shall be required in conformity with generally accepted accounting
principles.

                 (b)    The Seller represents, warrants and covenants that any
New Hampshire income taxes, including without limitation the New Hampshire
Business Profits Tax imposed under the provisions of New Hampshire RSA Chapter
77-A (taking into account credits in respect of the New Hampshire Business
Enterprise Tax imposed under RSA Chapter 77-E), associated with the Issuer will
be allocated to, and paid by, the Seller in accordance with the Amended and
Restated NU Tax Allocation Agreement, dated as of January 1, 1990, as amended
(the "NU Tax Sharing Agreement"), and that the applicable provisions of the NU
Tax Sharing Agreement, which currently provide for such treatment by their
reliance on federal income tax principles in allocating state income tax
liabilities, shall not be amended or modified by the Seller in contravention of
this Section 4.09(b) for so long as the Bonds are outstanding.

         Section 4.10.  Additional Sales of RRB Property. So long as any of the
                        --------------------------------
Bonds are outstanding, the Seller shall not sell any RRB property (as defined in
the Statute) to secure another issuance of rate reduction bonds (as defined in
the Statute) if it would cause the then existing ratings on any class of Bonds
from the Rating Agencies to be withdrawn or downgraded.

         Section 4.11.  Issuance Advice Letter. The Seller hereby agrees not to
                        ----------------------
withdraw the filing of the Issuance Advice Letter with the NHPUC.

         Section 4.12.  Maintenance of Working Papers. So long as any of the
                        -----------------------------
Bonds are outstanding, the Seller shall keep and maintain any and all working
papers, reports and other documents used by the firm of Independent certified
public accountants in the preparation of its letters delivered on the Issuance
Date pursuant to Section 2.10(g) of the Indenture and Section 6(h) of the
Underwriting Agreement.

                                   Article 5

                                   THE SELLER
                                   ----------

         Section 5.01.  Liability of Seller; Indemnities.
                        --------------------------------

                 (a)    The Seller shall be liable in accordance herewith only
to the extent of the obligations specifically undertaken by the Seller under
this Agreement.

                 (b)    (i)  In the event of a breach by the Seller of any
representation and warranty specified in Sections 3.08(c) or 3.08(e) that has a
material adverse effect on the Bondholders, the Seller shall repurchase the RRB
Property from the Issuer at a purchase price equal to the then outstanding
principal amount of the Bonds and all

                                      -12-

<PAGE>

accrued and unpaid interest thereon, excluding any premium or penalty of any
kind (the "Repurchase Price"), as of the Repurchase Date; provided, however,
           ----------------
that the Seller shall not be obligated to repurchase the RRB Property if (A)
within 90 days after the Date of Breach such breach is cured or the Seller takes
remedial action such that there is not and will not be a material adverse effect
on the Bondholders as a result of such breach and (B) either (1) if the Seller
had, immediately prior to the Date of Breach, a long term debt rating of at
least "A3" by Moody's and "BBB" or the equivalent by S&P or Fitch, and the
Seller enters into a binding agreement with the Issuer to pay any amounts
necessary so that all interest payments due on the Bonds during such 90-day
period will be paid in full, or (2) if the Seller does not have such long term
debt ratings, the Seller deposits, within two Business Days after the Date of
Breach, an amount in escrow with the Trustee sufficient, taking into account
amounts on deposit in the Collection Account which will be available for such
purpose, to pay all interest payments which will become due on the Bonds during
such 90-day period.


         (ii)  In the event of a breach by the Seller of any representation and
warranty specified in Sections 3.01, 3.03, 3.04, 3.05, 3.06, 3.08(a) or 3.08(b)
that has a material adverse effect on the Bondholders, if within 90 days after
the Date of Breach such breach has not been cured or the Seller has not taken
remedial action such that there is not and will not be a material adverse effect
on the Bondholders as a result of such breach, then the Seller shall repurchase
the RRB Property from the Issuer for the Repurchase Price on the Repurchase
Date.

         (iii) Notwithstanding any other provision of this Agreement, upon the
payment by the Seller of the Repurchase Price pursuant to this Section 5.01(b),
neither the Issuer nor any other Person shall have any other claims, rights or
remedies against the Seller under, arising from or with respect to this
Agreement, except as set forth in Section 5.01(h).


     (c) Subject to Section 5.01(i), the Seller shall indemnify the Issuer, the
Trustee, the State of New Hampshire, the State Treasurer, agencies of the State
of New Hampshire and the Bondholders (each an "Indemnified Person" for purposes
                                               ------------------
of this Section 5.01(c) and Section 5.01(i)) for, and defend and hold harmless
each such Indemnified Person from and against, any and all taxes (other than
taxes imposed on Bondholders solely as a result of their ownership of Bonds)
that may at any time be imposed on or asserted against any such Person under
existing law as of the Closing Date as a result of the sale of the RRB Property
to the Issuer, including any sales, gross receipts, general corporation,
tangible personal property, privilege or license taxes; provided, however, that
the Bondholders shall be entitled to enforce their rights against the Seller
under this Section 5.01(c) solely through a cause of action brought for their
benefit by the Trustee.

     (d) Subject to Section 5.01(i), the Seller shall indemnify the Issuer, the
Trustee, the State of New Hampshire, the State Treasurer, agencies of the State
of New Hampshire and the Bondholders (each an "Indemnified Person" for purposes
                                               ------------------
of this Section 5.01(d) and Section 5.01(i)) for, and defend and hold harmless
each such Indemnified Person from and against, any and all taxes that may be
imposed on or asserted against any such Indemnified Person under existing law as
of the Closing Date

                                      -13-

<PAGE>

as a result of the issuance and sale by the Issuer of the Bonds, or the other
transactions contemplated herein, including any sales, gross receipts, general
corporation, tangible personal property, privilege or license taxes; provided,
however, that the Bondholders shall be entitled to enforce their rights against
the Seller under this Section 5.01(d) solely through a cause of action brought
for their benefit by the Trustee. The Seller shall be reimbursed for any
payments under this Section 5.01(d) from RRB Charge Collections as an Operating
Expense in accordance with the priorities set forth in Section 8.02(d) of the
Indenture.


     (e) Subject to Section 5.01(i), the Seller shall indemnify the Issuer and
the Bondholders (each an "Indemnified Person" for purposes of this Section
                          ------------------
5.01(e) and Section 5.01(i)) for, and defend and hold harmless each such Person
from and against, any and all liabilities, obligations, losses, actions, suits,
claims, damages, payments, costs or expenses of any kind whatsoever
(collectively, "Losses") that may be imposed on, incurred by or asserted against
                ------
each such Indemnified Person as a result of (i) the Seller's willful misconduct
or negligence in the performance of its duties or observance of its covenants
under this Agreement, or (ii) the Seller's breach in any material respect of any
of its representations and warranties contained in this Agreement (other than
the representations and warranties specified in Sections 3.01, 3.03, 3.04, 3.05,
3.06, 3.08(a), 3.08(b), 3.08(c) or 3.08(e), the breach of which are subject to
the repurchase obligation set forth in Section 5.01(b)), except in the case of
both clauses (i) and (ii) to the extent of Losses either resulting from the
willful misconduct or gross negligence of such Indemnified Person or resulting
from a breach of a representation and warranty made by such Indemnified Person
in any of the Basic Documents that gives rise to the Seller's breach; provided,
however, that the Bondholders shall be entitled to enforce their rights against
the Seller under this indemnification solely through a cause of action brought
for their benefit by the Trustee; provided, further, that the Seller may, at its
election and in full satisfaction of its obligations under this Section 5.01(e),
repurchase the RRB Property at the Repurchase Price, in which case neither the
Issuer nor any other Person shall have any other claims, rights or remedies
against the Seller under, arising from or with respect to this Agreement, except
as set forth in Section 5.01(h).

     (f) Indemnification under Sections 5.01(c), 5.01(d), 5.01(e) and 5.01(h)
shall survive the resignation or removal of the Trustee and the termination of
this Agreement and shall include reasonable fees and out-of-pocket expenses of
investigation and litigation (including reasonable attorneys' fees and
expenses), except as otherwise provided in this Agreement.

     (g) Without prejudice to any of the other rights of the parties, the Seller
will not be in breach of any representation or warranty as a result of a change
in law by means of a legislative enactment or constitutional amendment or (if
such means become available in the future) referendum or initiative petition.
Notwithstanding anything to the contrary in this Agreement, the Seller makes no
representation or warranty that any amounts actually collected in respect of the
RRB Charge will in fact be sufficient to meet payment obligations with respect
to the Bonds or that the assumptions used in calculating the RRB Charge will in
fact be realized nor shall the Seller be obligated to reduce, or accept a
reduction of, any rates or charges to which it would otherwise be entitled in
respect of services rendered or to be rendered to customers in

                                      -14-

<PAGE>

order to permit the payment of the RRB Charge (other than as provided in the
Finance Order with respect to other components of the "stranded cost recovery
charge" (as defined in the Statute)).

     (h) Subject to Section 5.01(i), the Seller shall indemnify and hold
harmless the Trustee, the State of New Hampshire, the State Treasurer, agencies
of the State of New Hampshire and any of their respective affiliates, officials,
officers, directors, employees, consultants, counsel and agents (each an
"Indemnified Person" for purposes of this Section 5.01(h) and Section 5.01(i))
 ------------------
against any and all Losses incurred by any of such Indemnified Persons as a
result of (i) the Seller's willful misconduct or negligence in the performance
of its duties or observance of its covenants under this Agreement or (ii) the
Seller's breach in any material respect of any of its representations and
warranties contained in this Agreement, except in the case of both clauses (i)
and (ii) to the extent of Losses either resulting from the willful misconduct or
gross negligence of such Indemnified Person or resulting from a breach of a
representation or warranty made by such Indemnified Person in any of the Basic
Documents that gives rise to the Seller's breach.

     (i) The Seller shall not be required to indemnify any Indemnified Person
under Sections 5.01(c), 5.01(d), 5.01(e) or 5.01(h) for any amount paid or
payable by such Indemnified Person in the settlement of any action, proceeding
or investigation without the written consent of the Seller, which consent shall
not be unreasonably withheld. Promptly after receipt by an Indemnified Person of
notice of its involvement in any action, proceeding or investigation, such
Indemnified Person shall, if a claim for indemnification in respect thereof is
to be made against the Seller under this Section 5.01, notify the Seller in
writing of such involvement. Failure by an Indemnified Person to so notify the
Seller shall relieve the Seller from the obligation to indemnify and hold
harmless such Indemnified Person under this Section 5.01 only to the extent that
the Seller suffers actual prejudice as a result of such failure. With respect to
any action, proceeding or investigation brought by a third party for which
indemnification may be sought under this Section 5.01, the Seller shall be
entitled to assume the defense of any such action, proceeding or investigation.
Upon assumption by the Seller of the defense of any such action, proceeding or
investigation, the Indemnified Person shall have the right to participate in
such action or proceeding and to retain its own counsel. The Seller shall be
entitled to appoint counsel of the Seller's choice at the Seller's expense to
represent the Indemnified Person in any action, proceeding or investigation for
which a claim of indemnification is made against the Seller under this Section
5.01 (in which case the Seller shall not thereafter be responsible for the fees
and expenses of any separate counsel retained by the Indemnified Person except
as set forth below); provided, however, that such counsel shall be reasonably
satisfactory to the Indemnified Person. Notwithstanding the Seller's election to
appoint counsel to represent the Indemnified Person in an action, proceeding or
investigation, the Indemnified Person shall have the right to employ separate
counsel (including local counsel), and the Seller shall bear the reasonable
fees, costs and expenses of such separate counsel if (i) the use of counsel
chosen by the Seller to represent the Indemnified Person would present such
counsel with a conflict of interest, (ii) the actual or potential defendants in,
or targets of, any such action include both the Indemnified Person and the
Seller and the Indemnified Person shall have

                                      -15-

<PAGE>

reasonably concluded that there may be legal defenses available to it that
are different from or additional to those available to the Seller, (iii) the
Seller shall not have employed counsel reasonably satisfactory to the
Indemnified Person to represent the Indemnified Person within a reasonable time
after notice of the institution of such action or (iv) the Seller shall
authorize the Indemnified Person to employ separate counsel at the expense of
the Seller. Notwithstanding the foregoing, the Seller shall not be obligated to
pay for the fees, costs and expenses of more than one separate counsel for the
Indemnified Persons (in addition to local counsel). The Seller will not, without
the prior written consent of the Indemnified Person, settle or compromise or
consent to the entry of any judgment with respect to any pending or threatened
claim, action, suit or proceeding in respect of which indemnification may be
sought under this Section 5.01 (whether or not the Indemnified Person is an
actual or potential party to such claim or action) unless such settlement,
compromise or consent includes an unconditional release of the Indemnified
Person from all liability arising out of such claim, action, suit or proceeding.

          (j) The remedies of the Issuer and the Bondholders provided in this
Agreement are each such Person's sole and exclusive remedies against the Seller
for breach of its representations and warranties in this Agreement.

of, Seller. Any Person (a) into which the Seller may be merged or consolidated,
----------
(b) that may result from any merger or consolidation to which the Seller shall
be a party or (c) that may succeed to the properties and assets of the Seller
substantially as a whole, which Person in the case described in the foregoing
clause (c) executes an agreement of assumption to perform every obligation of
the Seller hereunder, shall be the successor to the Seller under this Agreement
without further act on the part of any of the parties to this Agreement;
provided, however, that (i) if the Seller is the Servicer, no Servicer Default,
and no event which, after notice or lapse of time, or both, would become a
Servicer Default shall have occurred and be continuing, (ii) the Seller shall
have delivered to the Issuer and the Trustee an Officer's Certificate stating
that such consolidation, merger or succession and such agreement of assumption
comply with this Section and that all conditions precedent, if any, provided for
in this Agreement relating to such transaction have been complied with, (iii)
the Seller shall have delivered to the Issuer and the Trustee an Opinion of
Counsel stating that, in the opinion of such counsel (A) such consolidation,
merger or succession and such agreement of assumption comply with this Section
and that all conditions precedent provided for in this Agreement relating to
such transaction have been complied with and (B) either (1) all filings to be
made by the Seller, including filings with the NHPUC pursuant to the Statute and
filings under the applicable Uniform Commercial Code, have been executed and
filed that are necessary to preserve and protect fully the interests of the
Issuer and the Trustee in the RRB Property and reciting the details of such

the Issuer, with ten Business Days' prior written notice given to the Rating
Agencies and the prior written consent of the Trustee, but without the consent
of any of the Bondholders, to cure any ambiguity, to correct or supplement any
provisions in this Agreement or for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions in this Agreement or
of modifying in any manner the rights of the Bondholders; provided, however,
that such action shall not, as evidenced by an Officer's Certificate delivered
to the Issuer and the Trustee, adversely affect in any material respect the
interests of any Bondholder.

Issuer, with ten Business Days' prior written notice given to the Rating
Agencies and the prior written consent of the Trustee and the prior written

it shall be sufficient if such consent shall approve the substance thereof.

     Prior to the execution of any amendment to this Agreement, the Trustee
shall be entitled to receive and rely upon an Opinion of Counsel stating that
the execution of such amendment is authorized or permitted by this Agreement.
The Trustee may, but shall not be obligated to, enter into any such amendment
