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

          (a) On the Closing Date, the Buyer and the Sellers shall enter into

and obligations of the Sellers, direct or indirect, known or unknown, absolute
or contingent, which arise and are attributable to the period after the Closing

Section 2.3(a), other than Excluded Liabilities, in accordance with the
respective terms and subject to the respective conditions thereof.  Without
limitation of the foregoing, the following liabilities and obligations shall be
included in the Assumed Liabilities:

              (i)  all liabilities and obligations of the Sellers, to the extent
     and only to the extent arising and attributable to the period after the
     Closing Date, under (a) the Sellers' Agreements and the real property
     leases comprising a part of the Purchased Assets in accordance with the
     terms thereof, (b) the Permits and Environmental Permits that are
     transferred to Buyer and (c) the contracts, leases and other agreements

     Purchased Assets entered into by any Seller and any local government and in
     all cases involving agreements requiring Buyer's consent under Section 7.1,
     solely such agreements entered into with the prior written consent of
     Buyer); provided that Assumed Liabilities shall not include liabilities and
     obligations to the extent such liabilities and obligations, but for a
     breach or default by either of the Sellers, would have been paid, performed
     or otherwise discharged specifically by their terms or the terms hereof on
     or prior to the Closing Date or to the extent the same arise out of any
     such breach or default;

              (ii) all liabilities and obligations in respect of Taxes for
     which the Buyer is liable pursuant to Section 7.7;

                                      14

 
               (iii)  any liabilities and obligations associated with the
     Purchased Assets for which the Buyer has indemnified the Sellers pursuant
     to Section 9.1;

               (iv)   all liabilities and obligations with respect to the
     Transferred Employees for which the Buyer is responsible pursuant to
     Section 7.9;

               (v)    any liability, obligation or responsibilities under or
     related to former, current or future Environmental Laws, Environmental
     Matters or the common law, whether such liability or obligation or
     responsibility is known or unknown, contingent or accrued, arising as a
     result of or in connection with (a) any violation or alleged violation of
     Environmental Laws with respect to the ownership or operation of the
     Purchased Assets after the Closing Date; (b) compliance with applicable
     Environmental Laws with respect to the ownership or operation of the
     Purchased Assets after the Closing Date; (c) loss of life, injury to
     persons or property or damage to natural resources caused (or allegedly
     caused) by the presence or Release of Hazardous Substances at, on, in,
     under, adjacent to, or migrating from the Purchased Assets after the
     Closing Date, including, but not limited to, Hazardous Substances contained
     in building materials at the Purchased Assets or in the soil, surface
     water, sediments, groundwater, landfill cells, or in other environmental
     media at or adjacent to the Purchased Assets; (d) loss of life, injury to
     persons or property or damage to natural resources caused (or allegedly
     caused) by the offsite disposal, storage, transportation, discharge,
     Release or recycling of Hazardous Substances in connection with the
     ownership or operation of the Purchased Assets after the Closing Date; (e)
     the investigation and/or remediation of Hazardous Substances that have been
     Released at, on, in, under, adjacent to, or migrating from the Purchased
     Assets after the Closing Date, including, but not limited to, Hazardous
     Substances contained in building materials at the Purchased Assets or in
     the soil, surface water, sediments, groundwater, landfill cells, or in
     other environmental media at the Purchased Assets; (f) the investigation
     and/or remediation of Hazardous Substances that are disposed, stored,
     transported, discharged, Released or recycled at any off-site location
     after the Closing Date in connection with the ownership or operation of the
     Purchased Assets; and (g) any violation or alleged violation of
     Environmental Law, and any loss of life, injury to persons or property or
     damage to natural resources caused (or allegedly caused) by (i) negligent
     acts or omissions by the Buyer at any of the Purchased Assets; (ii) acts or
     omissions by the Buyer at any of the Purchased Assets which cause a
     condition not in violation of Environmental Law or not in need of
     remediation under Environmental Law on or prior to the Closing Date to be
     in violation of Environmental Law or in need of remediation under
     Environmental Law (including, without limitation, the Release or
     destabilization of Hazardous Substances which are in a stable or contained
     state and are in compliance with all applicable Environmental Laws); or
     (iii) negligent acts or omissions by the Buyer at any of the Purchased
     Assets after the Closing Date that exacerbate or aggravate any condition in
     violation of Environmental Law or in need of remediation under
     Environmental Law on the Closing Date, to the extent of any such negligent
     exacerbation or aggravation; provided, that the mere discovery or failure
     to discover by the Buyer of a violation of Environmental Law or a condition
     in need of remediation under Environmental Law which violation or condition
     existed on the Closing Date, in and of itself shall not be included in this
     clause (g); provided, that 

                                      15

 
     nothing set forth in this Section 2.3(a)(v) shall require the Buyer to
     assume any liabilities that are described in Section 2.4(v) or 2.4(vi);

              (vi)   all liabilities incurred by any of the Sellers for payment
     of Maintenance Expenditures and Capital Expenditures directly related to
     the Purchased Assets to the extent not included in the Maintenance and
     Capital Expenditures Amount and agreed to be reimbursed in writing by
     Buyer; and

              (vii)  with respect to the Purchased Assets, (a) any Tax that may
     be imposed by any state or local government on the ownership, sale,
     operation, or use of the Purchased Assets with respect to the periods after
     the Closing Date, including real or personal property Taxes except as
     otherwise provided in Section 7.7, (b) any software license transfer,
     reissuance or similar costs relating to any of the Purchased Assets and (c)
     Permitted Encumbrances which are permitted by definition to survive the
     Closing Date.

          (b) All of the foregoing liabilities and obligations to be assumed by
the Buyer under Section 2.3(a) (excluding any Excluded Liabilities) are referred
to herein as the "Assumed Liabilities."  None of the liabilities and obligations
of the Sellers assumed by Buyer are intended to be expanded, increased,
broadened or enlarged as to rights or remedies of third parties against the
Buyer as compared to such rights or remedies which such parties would have had
against the Sellers had the transactions contemplated by this Agreement not
taken place.

          (c) Subject to Section 9.2(f), the parties agree and acknowledge that
after the Closing Date the Buyer shall be entitled exclusively to control any
litigation, administrative or regulatory proceeding or investigation arising out
of or related to any Assumed Liabilities and the Sellers agree to promptly
notify the Buyer of the institution or commencement of any of the foregoing and
to cooperate fully with the Buyer in connection therewith (provided that
Sellers' cooperation need not include the payment of money or any other
financial accommodation).

     2.4  Excluded Liabilities.  Except as expressly stated in this Agreement to
          --------------------
the contrary, Buyer shall not assume and shall not be responsible for, and
Sellers shall be and remain liable for, the payment, performance or discharge of
any liability or obligation of Sellers whatsoever other than the Assumed
Liabilities. Sellers covenant and agree that they will fully discharge (or
mutually settle, compromise or, as provided in Section 9.1, indemnify the Buyer
against) all their respective liabilities and obligations as to which Sellers'
failure to so discharge or settle could result in an Encumbrance against any of
the Purchased Assets or a claim against Buyer, except the Assumed Liabilities.
All such liabilities and obligations not being assumed by Buyer pursuant to
Section 2.3 are herein called the "Excluded Liabilities." Without limitation of
the foregoing, the Excluded Liabilities shall include without limitation, the
following liabilities or obligations:

              (i)    any liabilities or obligations of any of the Sellers in
     respect of any Excluded Assets or other assets of the Sellers which are not
     Purchased Assets;

              (ii)   any liabilities or obligations in respect of Taxes for
     which any of the Sellers are liable pursuant to Section 7.7;

                                      16

 
               (iii) any liabilities or obligations of the Sellers with respect
     to commitments for the purchase or sale of power or fuel, other than under
     any Sellers' Agreement;

               (iv)  Except for obligations assumed by Buyer under Section 7.9,
     any liabilities or obligations relating to the Sellers' employment of,
     termination of employment of, provision of benefits to, and compensation of
     employees employed at the Purchased Assets, including but not limited to an
     employee whose employment principally relates to any of the Purchased
     Assets (a "Purchased Assets Employee"), and any personal injury,
     discrimination, harassment, wrongful discharge or other wrongful employment
     practice, unfair labor practice, claims for benefits (including claims
     arising under ERISA or workers' compensation laws), or similar claims or
     causes of action, known or unknown, absolute or contingent, asserted or
     unasserted, of any such person arising out of acts or omissions occurring
     or otherwise attributable to the period on or before the Closing Date;

               (v)   any liabilities, obligations, or responsibilities under or
     related to former, current or future Environmental Laws, Environmental
     Matters or the common law, whether such liability or obligation or
     responsibility is known or unknown, contingent or accrued, arising as a
     result of or in connection with (a) any violation or alleged violation of
     Environmental Laws with respect to the offsite disposal, storage,
     transportation, discharge, Release or recycling of Hazardous Substances on
     or prior to the Closing Date in connection with the ownership, operation or
     maintenance of the Purchased Assets; (b) compliance with applicable
     Environmental Laws with respect to the offsite disposal, storage,
     transportation, discharge, Release or recycling of Hazardous Substances on
     or prior to the Closing Date in connection with the ownership, operation or
     maintenance of the Purchased Assets; (c) loss of life, injury to persons or
     property or damage to natural resources (whether or not such loss, injury
     or damage was made manifest before or after the Closing Date) caused (or
     allegedly caused) by the offsite disposal, storage, transportation,
     discharge, Release or recycling of Hazardous Substances on or prior to the
     Closing Date in connection with the Purchased Assets, or the ownership,
     operation or maintenance of the Purchased Assets; and (d) the investigation
     and/or remediation (whether or not such investigation or remediation
     commenced on or before the Closing Date) of Hazardous Substances that are
     disposed, stored, transported, discharged, Released or recycled, or the
     arrangement for such activities at any off-site location, on or prior to
     the Closing Date, in connection with the Purchased Assets or the ownership,
     operation or maintenance of the Purchased Assets;

               (vi)  any liabilities, obligations or responsibilities under or
     related to former, current or future Environmental Laws, Environmental
     Matters or the common law, whether such liability, obligation or
     responsibility is known or unknown, contingent or accrued, arising as a
     result of or in connection with (a) any violation or alleged violation of
     Environmental Laws with respect to the ownership or operation of the
     Purchased Assets on or prior to the Closing Date; (b) compliance with
     applicable Environmental Laws with respect to the ownership or operation of
     the Purchased Assets on or prior to the Closing Date; (c) loss of life,
     injury to persons or property or damage to natural resources (whether or
     not such loss, injury or damage was made manifest before or after the
     Closing Date) caused (or allegedly caused) by the presence or Release of
     Hazardous 

                                      17

 
     Substances at, on, in, under, adjacent to or migrating from the Purchased
     Assets on or prior to the Closing Date, including, but not limited to,
     Hazardous Substances contained in building materials at the Purchased

     landfill cells, or in other environmental media at or adjacent to the
     Purchased Assets on or prior to the Closing Date;

               (vii)  any liabilities or obligations of Sellers relating to any
     benefit plan, or to any "employee pension benefit plan" (as defined in
     Section 3(2) of ERISA) of Sellers, whether or not terminated, established,
     maintained or contributed to by any of the Sellers or any of their ERISA
     Affiliates at any time, or to which any of the Sellers or any of their

               (viii) BHE's obligations under the HQ Transmission Support

     Subject to Section 9.2(f), the parties agree and acknowledge that the
Sellers shall be entitled exclusively to control any litigation, administrative
or regulatory proceeding, investigation or inquiry of any kind or nature arising
out of or related to any Excluded Liabilities, and the Buyer agrees to promptly

                                  ARTICLE III

                                PURCHASE PRICE
                                --------------

     3.1  Purchase Price.  Subject to the express provisions of this Agreement,
          --------------
the purchase price for the Purchased Assets shall consist of the Initial Payment
and the Additional Payments 

                                      18

 
(collectively, the "Purchase Price"). The "Initial Payment" shall be an amount
equal to the sum of (i) $89,000,000 and (ii) the Adjustment Amount. The
"Additional Payments" shall consist of the payment by Buyer to BHE of $400,000
per year (or pro rata portion thereof) for the term of the HQ Transmission
Support Agreements, to be payable as provided in the HQ Transfer Agreement.

     3.2  Purchase Price Adjustment.
          ------------------------- 

          (a) No later than five (5) Business Days before the Closing Date, BHE
shall notify the Buyer in writing of the Estimated Adjustment Amount, which
shall be payable by the Buyer to BHE as provided in Section 4.2.

          (b) Within thirty (30) days after the Closing, BHE shall prepare and
deliver to the Buyer a statement (the "Adjustment Statement") which reflects (i)
the net book value, as reflected on the books of the Sellers as of the Closing
Date, of BHE's interest under the Wyman Agreements in the fuel inventory at
Wyman Station (the "Inventory Adjustment Amount") and (ii) the Maintenance and
Capital Expenditures Amount applicable to the Purchased Assets.  The Inventory
Adjustment Amount and the Maintenance and Capital Expenditures Amount are
referred to collectively as the "Adjustment Amount."  The Inventory Adjustment
Amount will be based on an inventory survey conducted within five (5) Business
Days prior to the Closing Date consistent with Sellers' current inventory
procedures, and  Buyer will be entitled to have a Buyer Representative observe
such inventory survey.  The Adjustment Statement shall be prepared using the
same generally accepted accounting principles, policies and methods as the
Sellers have historically used in connection with the calculation of the items
reflected on the Adjustment Statement.  The Buyer agrees to cooperate with BHE
in connection with the preparation of the Adjustment Statement and related
information and shall provide to BHE such books, records and information as may
be reasonably requested from time to time.

          (c) The Buyer may dispute the Inventory Adjustment Amount or the
Maintenance and Capital Expenditures Amount; provided, however, that the Buyer
shall notify BHE in writing of the disputed amount, and the basis of such
dispute, within ten (10) Business Days of the Buyer's receipt of the Adjustment
Statement.  In the event of a dispute with respect to any part of an Adjustment
Amount, the Buyer and BHE shall attempt to reconcile their differences and any
resolution by them as to any disputed amounts shall be final, binding and
conclusive on the parties.  If the Buyer and BHE are unable to reach a
resolution of such differences within thirty (30) days of receipt by BHE of the
Buyer's written notice of dispute, the Buyer and BHE shall submit the amounts
remaining in dispute for determination and resolution to the Independent
Accounting Firm, which shall be instructed to determine and report to the
parties, within thirty (30) days after such submission, upon such remaining
disputed amounts, and such report shall be final, binding and conclusive on the
parties hereto with respect to the amounts disputed.  The fees and disbursements
of the Independent Accounting Firm shall be shared equally.

          (d) Within ten (10) Business Days after the Buyer's receipt of the
Adjustment Statement, if the Adjustment Amount is less than the Estimated
Adjustment Amount, the Sellers shall refund the difference to the Buyer, and if
the Adjustment Amount is greater than the Estimated Adjustment Amount, the Buyer
shall pay the difference to BHE on behalf of the 

                                      19

 
Sellers; provided, that if there is a dispute with respect to any amount on the
Adjustment Statement, the Buyer shall immediately pay to BHE on behalf of the
Sellers any undisputed amounts (to the extent not previously paid). Within five
(5) Business Days after the final determination of any amounts on the Adjustment
Statement, the Buyer shall pay to BHE on behalf of the Sellers an amount equal
to (x) the Adjustment Amount as finally determined to be payable with respect to
the Adjustment Statement less (y) the sum of the Estimated Adjustment Amount and
any additional undisputed amount theretofore paid by the Buyer to the Sellers;
provided, however, that if such amount shall be less than zero, then the Sellers
will pay to the Buyer the amount by which such amount is less than zero. Any
amount paid or refunded under this Section 3.2(d) shall be paid or refunded with
interest for the period commencing on the Closing Date through the date of
payment, calculated at the "prime rate" for domestic banks as published in The
Wall Street Journal (Northeast Edition) in the "Money Rates" section on the
Closing Date, in cash by Federal or other wire transfer of immediately available
funds.

     3.3  Allocation of Purchase Price. Each of the Buyer and the Sellers agree
          ---------------------------- 
to allocate the Purchase Price among the Purchased Assets in accordance with
Schedule 3.3. Each of the Buyer and the Sellers agree to file Internal Revenue
Service Form 8594 with their Federal Income Tax Returns for the taxable year
that includes the Closing Date, and to file all Federal, state, local and
foreign Tax Returns, each in accordance with the allocation of the Purchase
Price among the tax categories of the Purchased Assets set forth above. Each of
the Buyer and the Sellers shall report the transactions contemplated by this
Agreement for Federal Income Tax and all other Tax purposes in a manner
consistent with such allocation. Each of the Buyer and the Sellers agree to
provide the others promptly with any other information and cooperation required
to complete Form 8594. Each of the Buyer and the Sellers shall notify and
provide the others with reasonable assistance in the event of an examination,
audit or other proceeding regarding the agreed-upon allocation of the Purchase
Price.

     3.4  Proration.
          --------- 

          (a)  The Buyer and the Sellers agree that all of the items normally
prorated, including those listed below, relating to the business and operation
of the Purchased Assets will be prorated as of the Closing Date, with the
Sellers liable with respect to Purchased Assets being sold by them to the extent
such items relate to any time period through the Closing Date, and the Buyer
liable to the extent such items relate to periods subsequent to the Closing Date
with, to the extent practicable, a cash settlement on the Closing Date:

               (i)    personal property and real estate taxes, assessments and
     other charges, if any, by the municipality, on the basis of the
     municipality's fiscal year, on or with respect to the business and
     operation of the Purchased Assets;

               (ii)   rent, Taxes and other items payable by or to a Seller
     under any of the Sellers' Agreements assigned to and assumed by the Buyer
     hereunder which are associated with the Purchased Assets;

               (iii)  any permit, license, registration, compliance assurance
     fees or other fees with respect to any Permit and Environmental Permit
     associated with the Purchased Assets;

                                      20

 
              (iv) sewer rents and charges for water, telephone, electricity
     and other utilities; and

              (v)  fixed monthly charges to the NEPOOL.

          (b) In connection with the prorations referred to in (a) above, in the
event that actual figures are not available at the Closing Date, the proration
shall be based upon the actual Taxes or fees for the preceding year (or
appropriate period) for which actual Taxes or fees are available and such Taxes
or fees shall be reprorated upon request of the affected Sellers, on the one
hand, or the Buyer, on the other hand, made within sixty (60) days after the
date that the actual amounts become available.  The Sellers and the Buyer agree
to furnish each other with such documents and other records as may be reasonably
requested in order to confirm all adjustment and proration calculations made
pursuant to this Section 3.4.

          (c) To the extent required by any approval of the transfer of the FERC
project licenses related to the Hydroelectric Assets, Sellers agree to pay all
annual charges accrued under such licenses as of the Closing Date.

     3.5  Exclusion of Purchased Assets from Closing.

          (a) In the event (i) any Purchased Asset cannot be conveyed on the
Closing Date due to the failure on the part of Sellers to satisfy any condition
in Article VIII (other than Section 8.1(c)) required on their part to be
satisfied or (ii) the condition set forth in Section 8.1(c) is not satisfied
(without regard to any qualifications with respect to Material Adverse Effect
contained therein), then:

          (1) if the aggregate value of the Purchased Asset or group of
Purchased Assets that are so affected equals 10% or more of the Purchase Price
or if the exclusion of such asset(s) materially impairs the use of another
Purchased Asset or a group of Purchased Assets as historically used the
aggregate value of which equals 10% or more of the Purchase Price, then at
Buyer's option, Buyer may (i) terminate this Agreement pursuant to Section
10.1(d) (provided that Buyer shall not be entitled to terminate this Agreement
if the sole affected Purchased Asset is the Veazie Hydro Project), or (ii)
proceed with the Closing and the Purchase Price shall be decreased by an amount
equal to the aggregate value of such Purchased Asset or group of Purchased
Assets so affected; or

          (2) if the aggregate value of the Purchased Asset or group of
Purchased Assets that are so affected equals less than 10% of the Purchase Price
or if the exclusion of such asset(s) materially impairs the use of another
Purchased Asset or a group of Purchased Assets as historically used the
aggregate value of which equals 10% or less of the Purchase Price, the Closing
shall proceed and the Purchase Price shall be decreased by an amount equal to
the aggregate value of the Purchased Asset or group of Purchased Assets so
affected.

          (b) For purposes of this Section 3.5, the "value" of any asset shall
be determined in accordance with the allocation of the Purchase Price as set
forth on Schedule 3.3.  In the case of such an adjustment to the Purchase Price,
the Maintenance and Capital Expenditure Amount shall be reduced by the amounts
thereof attributable to such assets.

                                      21

 
          (c) Notwithstanding Section 3.5(a)(1) above, Buyer agrees that in the
event BHE is unable to convey its interest in Bangor-Pacific to Buyer at Closing
for any reason, Buyer shall nevertheless proceed with the Closing and the
Purchase Price shall be reduced by the amount allocated to BHE's interest in
Bangor-Pacific as set forth on Schedule 3.3.

                                  ARTICLE IV

provisions of any note, bond, mortgage, indenture, license, agreement or other
instrument or obligation to which any Seller is a party or by which any Seller
or any of the Purchased Assets may be bound, except for such defaults (or rights

                                      37

 
     discretion, if the aggregate payment under such commitment and all other

     expected to exceed $1 million;

               (iv)   sell, lease (as lessor), transfer or otherwise dispose of

               (vii)  make or approve any increase in the compensation payable
     by Sellers to any of the Employees (including, without limitation, salary,
     bonuses and benefits) except for increases consistent with past practices
     as heretofore disclosed to the Buyer; provided, however, that the foregoing
     shall not restrict the granting by the Sellers of voluntary early
     retirement and severance packages in accordance with the Employee
     Transition Plan solely at the Sellers' expense;

               (viii) enter into any oral or written contracts, agreements,

     with respect to the Purchased Assets, in excess of $500,000 which have a
     term in excess of six (6) months, unless it is terminable by the Sellers
     and their assignee without penalty or premium upon not more than 30 days'
     notice, or (C) outside the ordinary course of business.

          (b)  Without limiting the generality of the first sentence of Section
7.1, prior to the Closing Date, except with the prior written consent of the
Buyer, the Sellers will, with respect to the Purchased Assets:

               (i)    consult with the Buyer as to the making of any material
     decisions or the taking of any material actions in matters other than in

               (iv)   keep in force at not less than their present limits all
     policies of insurance to the extent reasonably practicable in light of the
     prevailing market conditions in the insurance industry and promptly notify
     Buyer of the cancellation of any such policy or any material modification
     thereto; and

                                      38

 
               (v) maintain their customary business relationships with any
     lessor, licensor, customer or supplier of any Seller, and maintain their

contrary, the Sellers may, in their sole discretion (i) make Maintenance
Expenditures and Capital Expenditures up to but not to exceed the Maintenance
and Capital Expenditures Amount, (ii) make, at the Sellers' expense, such other
maintenance and capital expenditures as the Sellers deem necessary, and (iii)
take any action in respect of the Purchased Assets (not otherwise described in
(a) or (b)) that does not adversely affect the Purchased Assets or the Assumed
Liabilities.

     7.2  Access to Information.
          --------------------- 

          (a)  Between the date of this Agreement and the Closing Date, the
Sellers will, during ordinary business hours and upon reasonable notice (i) give
the Buyer and the Buyer Representatives reasonable access to all books, records,
plants, offices and other facilities and properties constituting the Purchased
Assets or related to the Business or the Assumed Liabilities unless such access
would violate applicable law; (ii) permit the Buyer and its representatives to
make such reasonable inspections thereof as the Buyer may reasonably request;
(iii) furnish the Buyer with such financial and operating data and other
information with respect to the Purchased Assets, the related Business and the
Assumed Liabilities as the Buyer may from time to time reasonably request; and
(iv) furnish the Buyer a copy of each report, Schedule or other document filed
or received by them with respect to the Purchased Assets or the related Business
with the SEC, MPUC, MDEP, FERC, DOE, EPA or other relevant regulatory agency;
provided, however, that (A) any such investigation shall be conducted in such a
manner as not to interfere unreasonably with the operation of the Purchased
Assets, (B) the Sellers shall not be required to take any action which would
constitute a waiver of the attorney-client privilege and (C) the Sellers need
not supply the Buyer with any information which the Sellers, in their reasonable
judgment, are under a legal obligation not to supply, provided that Sellers
describe, to the extent permissible, the nature of the information withheld.
Notwithstanding anything in this Section 7.2 to the contrary, (i) the Sellers
will only furnish or provide such access to personnel and medical records as is
required by law, and (ii) the Buyer shall not have the right to perform or
conduct any environmental sampling or testing at, in, on, or underneath or
adjacent to the Purchased Assets.

          (b)  All information furnished to or obtained by the Buyer and the
Buyer Representatives pursuant to this Section 7.2 shall be "Information" for
purposes of Section 7.11 hereof.

          (c)  Subject to the last two sentences of this paragraph (c), for a
period of ten years after the Closing Date, the Sellers and their
representatives shall have reasonable access to all of the books and records of
the Purchased Assets transferred to the Buyer hereunder to the extent that such
access may reasonably be required by the Sellers in connection with matters
relating to or affected by the operation of the Purchased Assets prior to the
Closing Date.  Such access shall be afforded by the Buyer upon receipt of
reasonable advance notice and during normal business hours.  The Sellers shall
be solely responsible for any costs or expenses incurred 

                                      39

 
by them pursuant to this Section 7.2(c). If the Buyer shall desire to dispose of
any such books and records prior to the expiration of such ten-year period, the
Buyer shall, prior to such disposition, give the Sellers a reasonable
opportunity, at the Sellers' expense, to segregate and remove such books and
records as the Sellers may select.

          (d) Subject to the last two sentences of this paragraph (d), for a
period of ten years after the Closing Date, the Buyer and Buyer Representatives
shall have reasonable access to all of the books and records of the Purchased
Assets retained by the Sellers to the extent that such access may reasonably be
required by the Buyer in connection with matters relating to or affected by the
operation of the Purchased Assets subsequent to the Closing Date; provided,
however, that Sellers shall not be required to provide access to personnel or
medical records except as required by law.  Such access shall be afforded by the
Sellers upon receipt of reasonable advance notice and during normal business
hours.  In addition, the Sellers will cooperate in the defense of any action
brought against the Buyer by a former employee of the Sellers.  The Buyer shall
be solely responsible for any costs or expenses incurred by it pursuant to this
Section 7.2(d).  If any Seller shall desire to dispose of any such books and
records prior to the expiration of such ten-year period, such Seller shall,
prior to such disposition, give the Buyer a reasonable opportunity at the
Buyer's expense, to segregate and remove such books and records as the Buyer may
select; provided, however, that the Sellers will use best efforts to preserve
all employment and medical records of those employees who are hired by the Buyer
as of the Closing Date, for a period of not less than ten (10) years from the
Closing Date.

          (e) If within ten years after the Closing Date the MPUC shall commence
an investigation of the reasonableness of any term or condition of this
Agreement, Buyer shall fully cooperate with the Sellers in providing any
information or testimony which may be helpful to Sellers in establishing the
reasonableness of the terms and conditions of the Agreement.  Sellers shall be
responsible for any costs or expenses incurred by Buyer pursuant to this Section
7.2(e).

     7.3  Expenses.  Except to the extent specifically provided herein, whether
          -------- 
or not the transactions contemplated hereby are consummated, all costs and
expenses incurred in connection with this Agreement and the transactions
contemplated hereby shall be borne by the party incurring such costs and
expenses, including, without limitation, any expenses associated with litigation
arising out of this Agreement or any of the transactions contemplated hereunder.
Notwithstanding anything to the contrary herein, the Buyer will be responsible
for (a) all costs and expenses associated with the obtaining of any title
insurance policy and all endorsements thereto that the Buyer elects to obtain,
and (b) all filing fees of Buyer as an acquiring person under the HSR Act.
Sellers and Buyer each represent and warrant to the other, respectively, that,
except for Reed Consulting Group, Inc., which is acting for and at the expense
of the Sellers, no broker, finder or other person is entitled to any brokerage
fees, commissions or finder's fees in connection with the transactions
contemplated hereby by reason of any action taken by the party making such
representation. The Sellers and Buyer will pay to the other, or otherwise
discharge, and will indemnify and hold the other harmless from and against, any
and all claims or liabilities for all brokerage fees, commissions, and finders'
fees (other than as described above) incurred by reason of any action taken by
the indemnifying party.

                                      40

 
     7.4  Further Assurances.
          ------------------ 

          (a) Each of the parties hereto will use its reasonable best efforts to
take, or cause to be taken, all actions, and to do, or cause to be done, all
things necessary, proper or advisable under applicable laws and regulations to
consummate and make effective the sale of the Purchased Assets pursuant to this
Agreement.  From time to time after the Closing Date, without further
consideration, the Sellers will reasonably cooperate with the Buyer in its
efforts to maximize any tax benefits associated with the Purchased Assets with
respect to periods following the Closing Date and to minimize the tax costs
associated with the transactions contemplated hereby, and will, at their own
expense, execute and deliver such documents to the Buyer as the Buyer may
reasonably request in order to more effectively vest in the Buyer the Sellers'
title to the Purchased Assets.  From time to time after the Closing Date, the
Buyer will reasonably cooperate with the Sellers in their efforts to maximize
any tax benefits associated with the Purchased Assets with respect to periods
prior to the Closing Date and to minimize the tax costs associated with the
transactions contemplated hereby, and will, at its own expense, execute and
deliver such documents to the Sellers as the Sellers may reasonably request in
order to more effectively consummate the sale of the Purchased Assets pursuant
to this Agreement.

          (b) Subject to Section 3.5, in the event that any Purchased Asset
shall not have been conveyed to the Buyer at the Closing, the Sellers shall,
subject to Section 7.4(c), use their best efforts to convey such asset to the
Buyer as promptly as is practicable after the Closing.  In the event that any
Easement shall not have been retained by a Seller after the Closing, the Buyer
shall use its best efforts to grant such Easement to such Seller as promptly as
is practicable after the Closing.  Nothing contained herein shall require the
Sellers or the Buyer to institute any litigation or to pay or agree to pay any
sum of money to convey such asset or grant such easement.

          (c) To the extent that the Sellers' rights under any Sellers'
Agreement may not be assigned without the consent of another Person which
consent has not been obtained, this Agreement shall not constitute an agreement
to assign the same if an attempted assignment would constitute a breach thereof
or be unlawful, and the Sellers, at their expense, shall use their best efforts
to obtain any such required consent(s) as promptly as possible.  The Sellers and
the Buyer agree that if any consent to an assignment of any Sellers' Agreement
shall not be obtained or if any attempted assignment would be ineffective or
would impair the Buyer's rights and obligations under the Sellers' Agreement in
question so that the Buyer would not in effect acquire the benefit of all such
rights and obligations, the Sellers, to the maximum extent permitted by law and
such Sellers' Agreement, shall with respect to any such Sellers' Agreement,
appoint the Buyer to be the Sellers' agent with respect to such Sellers'
Agreement, and enter into such reasonable arrangements with the Buyer as are
necessary to provide the Buyer with the benefits and obligations of such
Sellers' Agreement.  Schedule 1.1(a)(53) identifies those agreements that will
be assigned to the Buyer and those agreements which will be governed by the
preceding sentence.

          (d) Sellers and Buyer covenant and agree to negotiate and enter into
in good faith such further agreements as may be necessary for operating the
Purchased Assets after the Closing Date.

                                      41

 
          (e) The parties agree and acknowledge that certain of the Permits
issued by the FERC include assets included in the Purchased Assets as well as
other assets of the Sellers which are not to be conveyed to the Buyer pursuant
to this Agreement.  In connection with the parties' performance of their
obligations under Section 7.4(a) hereof, the parties agree to take all action
necessary in order that any such Permit, when transferred to the Buyer, will be
modified appropriately to reflect the retention by the Sellers of the assets to
be retained by them and the retention by the Sellers of any necessary Permit
with respect to such retained assets.

          (f) BHE agrees to consult with Buyer in connection with any matter on
which the participants in NEPOOL are entitled to vote or give consent or approve
and which could affect the Purchased Assets in any material respect.

     7.5  Public Statements.  Between the date of this Agreement and the Closing
          ----------------- 
Date, the Sellers and the Buyer agree that they will consult with each other in
advance of making any public announcement or press release, or otherwise
disclosing any information, relating to the execution of this Agreement or any
transactions contemplated hereby, or otherwise relating to the Purchased Assets,
and will negotiate in good faith with respect to the form, content and timing
thereof and shall not issue any such release without the prior approval of the
other party; provided, however, that each party reserves the right to make such
statements to regulatory authorities in the ordinary course of business or as
are required, in the opinion of its counsel, by applicable law.

     7.6  Consents and Approvals. 
          ---------------------- 

          (a) The Sellers and the Buyer shall each file or cause to be filed
with the Federal Trade Commission and the United States Department of Justice
any notifications required to be filed under the HSR Act and the rules and
regulations promulgated thereunder with respect to the transactions contemplated
hereby.  The parties shall consult with each other as to the appropriate time of
filing such notifications and shall use their best efforts to make such filings
at the agreed upon time, to respond promptly to any requests for additional
information made by either of such agencies, and to cause the waiting periods
under the HSR Act to terminate or expire at the earliest possible date after the
date of filing.  Buyer will pay all filing fees of Buyer as an acquiring person
under the HSR Act in accordance with Section 7.3, and each of the parties shall
bear its own costs of the preparation of any filing.

          (b) The Sellers and the Buyer shall cooperate with each other and (i)
promptly prepare and file all necessary documents, (ii) effect all necessary
applications, notices, petitions and filings and execute all agreements and
documents, (iii) use their respective best efforts to obtain the transfer or
reissuance to the Buyer of all necessary Permits, Environmental Permits,
consents, approvals and authorizations of all governmental bodies, including
without limitation Permits related to the 345 Line, and (iv) use their
respective best efforts to obtain all necessary consents, approvals and
authorizations of all other parties, in the case of each of the foregoing
clauses (i), (ii), (iii) and (iv), necessary or advisable to consummate the
transactions contemplated by this Agreement (including, without limitation, the
Seller Required Regulatory Approvals, the Seller Required Consents and the Buyer
Required Regulatory Approvals) or for the Buyer to own, operate or maintain, on
and after the Closing Date, the Purchased Assets substantially as such assets
have been historically owned, operated and maintained by the Sellers 

                                      42

 
prior to the date of this Agreement, or required by the terms of any note, bond,
mortgage, indenture, deed of trust, license, franchise, permit, concession,
contract, lease or other instrument to which any Seller or the Buyer is a party
or by which either of them is bound. Each of the Sellers and the Buyer shall
have the right to review in advance all characterizations of the information
relating to the transactions contemplated by this Agreement which appear in any
filing made in connection with the transactions contemplated hereby.

          (c) The Sellers shall use their best efforts prior to and, if
necessary, after the Closing Date to obtain the Seller Required Consents, and
the Buyer shall use its best efforts prior to and, if necessary, after the
Closing Date to obtain the Buyer Required Regulatory Approvals. If any such
consent or approval is not obtained, the Sellers and the Buyer agree to
cooperate in any reasonable arrangements (which may include, in the case of
leased property, a sublease thereof) designed to provide for the Buyer all of
the benefits (and to assure that the Sellers will be effectively relieved from
related liabilities) under such contract, agreement, lease, commitment or right,
including enforcement for the benefit of the Buyer, at the Sellers' expense, of
any and all rights of the Sellers against the other party or parties thereto.
Nothing in this Agreement shall be construed as an attempt or agreement to
assign (i) any contract which is nonassignable without the consent of the other
party or parties thereto unless such consent shall have been given, or (ii) any
contract or claim as to which all the remedies for the enforcement thereof would
not pass to the Buyer as an incident of the assignments provided for by this
Agreement.

          (d) Each of Buyer and the Sellers mutually agree for the benefit of
the other that, between the date of this Agreement and the Closing Date, neither
Buyer, Sellers nor any of their respective controlled Affiliates will enter into
any agreement, commitment or undertaking which would reasonably be expected to
impair the ability of Buyer and Sellers to complete the purchase and sale of the
Purchased Assets at the earliest time that the conditions set forth in Article
VIII are satisfied.

     7.7  Tax Matters.
          ----------- 

          (a) All transfer and sales or use taxes incurred in connection with
this Agreement and the transactions contemplated hereby shall be borne by the
Buyer, whether imposed on the Buyer or the Sellers, and the Buyer, at its own
expense, will file, to the extent required by applicable law, all necessary Tax
Returns and other documentation with respect to all such transfer or sales
taxes, and, if required by applicable law, the Sellers will join in the
execution of any such Tax Returns or other documentation and will take such
positions therein as are reasonably requested by the Buyer.  Sellers shall be
responsible for the payment of all their respective Taxes payable with respect
to any period or portion thereof prior to the Closing Date.

          (b) With respect to Taxes to be prorated in accordance with Section
3.4 of this Agreement only, the Buyer shall prepare and timely file all Tax
Returns required to be filed with respect to the Purchased Assets, if any, and
shall duly and timely pay all such Taxes, whether imposed on the Buyer or the
Sellers, shown to be due on such Tax Returns.  The Buyer's preparation of any
such Tax Returns shall be subject to the Sellers' approval, which approval shall
not be unreasonably withheld.  The Buyer shall make such Tax Returns available
for the Sellers' review and approval no later than fifteen (15) Business Days
prior to the due date for 

                                      43

 
filing such Tax Return. Within ten (10) Business Days after receipt of such Tax
Return, the Sellers shall pay to the Buyer the Sellers' proportionate share of
the amount shown as due on such Tax Returns determined in accordance with
Section 3.4 of this Agreement to the extent Sellers are liable therefor pursuant
thereto and to the extent not already paid or accrued as a liability on Sellers'
balance sheets as of June 30, 1998.

          (c) After the Closing Date, Buyer and Sellers shall provide each other

reasonably may request in (A) filing any Tax Return, amended Tax Return or claim
for Tax refund, (B) determining any Tax liability or a right to refund of Taxes,
(C) conducting or defending any audit or other proceeding in respect of Taxes or
(D) effectuating the terms of this Agreement.  The parties shall retain all Tax
Returns, schedules and work papers, and all material records and other documents
relating thereto, until the expiration of the statute of limitation (and, to the
extent notified by any party, any extensions thereof) of the taxable years to
which such returns and other documents relate and, unless such Tax returns and
other documents are offered and delivered to Sellers or Buyer, as applicable,
until the final determination of any Tax in respect of such years.  Any
information obtained under this Section 7.7(c) shall be kept confidential,
except as may be otherwise necessary in connection with filing any Tax Return,
amended Tax Return, or claim for Tax refund, determining any Tax liability or
right to refund of Taxes, or in conducting or defending any audit or other
proceeding in respect of Taxes.  Notwithstanding the foregoing, neither Seller
nor Buyer, nor any of their Affiliates, shall be required unreasonably to
prepare any document, or determine any information not then in its possession,
in response to a request under this Section 7.7(c).

          (d) (i) Sellers shall use reasonable efforts to cause to be prepared
and filed all Tax Returns of Bangor-Pacific for all taxable periods ending on or
prior to the Closing Date and cause to be paid all Taxes relating to such Tax
Returns.

          Upon request of Buyer, PHC shall cooperate with Buyer in making a Code
Section 754 election by Bangor-Pacific with respect to obtaining an adjustment
to the basis of Bangor-Pacific's assets under Code Section 743.  For purposes of
the allocations pursuant to Code Sections 755 and 1060 with respect to the Code
Section 754 elections, Buyer and PHC mutually agree that property, plant and
equipment may be assigned a value equal to fair market value and receivables may
be assigned a value equal to the face amount thereof net of any bad debts for
purposes of any such election.  If a Code Section 754 election is to be made,
Buyer shall prepare and submit within one hundred eighty (180) days after the
Closing Date an allocation consistent with the allocation described above to
Sellers for their review and approval, which shall not be unreasonably withheld.
Provided that the other partners in Bangor-Pacific have agreed to cooperate with
Buyer in causing Bangor-Pacific to make a Code Section 754 election, at the
election of Buyer, Buyer and PHC shall timely complete and file the statement
required by Treasury Regulation 1.743-1 and IRS Form 8594 consistent with such
allocation, shall provide a copy of such form to the other party hereto and
shall file a copy of such form with its federal income tax return for the period
that includes the Closing Date.  Sellers agree not to take any action to rescind
any such Code Section 754 election now or hereafter in effect with respect to
the assets of Bangor-Pacific.

                                      44

 
               (ii)   Sellers shall have the right, at Sellers' sole expense, to
     represent the interests of Bangor-Pacific in any Tax audit or
     administrative or court proceeding relating to Tax Returns described in
     Section 7.7(d)(i) with respect to which any Seller may be liable for Taxes
     (including any such proceedings relating to Bangor-Pacific); provided,
                                                                  -------- 
     however, that Buyer shall have the right to participate in any such audit
     -------                                                                  
     or proceeding to the extent that any such audit or proceeding may affect
     the Tax liability of Buyer, any of its Affiliates, or Bangor-Pacific for
     any period ending after the Closing Date (with the right to consent to any
     settlement which may affect the Tax liability of Buyer, which consent shall
     not be unreasonably withheld) and to employ counsel of its choice at its
     own expense for purposes of such participation.

               (iii)  Buyer shall notify Sellers in writing, as promptly as
     practicable, upon receipt by Buyer, any Affiliate of Buyer, or Bangor-
     Pacific of notice of any pending or threatened Tax audits or assessments
     relating to the income, properties or operations of any Seller or Bangor-
     Pacific, in each case for Pre-Closing Periods only, so long as Pre-Closing
     Periods remain open; provided, however, that failure by Buyer to comply
                          --------  -------                                 
     with this Section 7.7(d)(iii) shall not affect Buyer's right to
     indemnification relating to Taxes if such failure does not prejudice the
     rights of Sellers. Sellers shall notify Buyer in writing as promptly as
     practicable upon receipt by Sellers or any Affiliate of Sellers of notice
     of any pending or threatened Tax audits or assessments relating to the
     income, properties or operations of Bangor-Pacific.

          (e)  The obligations of the Buyer and Sellers under this Section 7.7
shall survive the Closing and shall continue until the expiration of the
applicable statute of limitations.

     7.8  Supplements to Schedules. Prior to the Closing Date, the Sellers shall
          ------------------------
supplement or amend the Schedules required by this Agreement with respect to any
matter relating to the Purchased Assets hereafter arising which, if existing or
occurring at the date of this Agreement, would have been required to be set
forth or described in such Schedules. No supplement or amendment of any Schedule
made pursuant to this Section shall be deemed to cure any breach of any
representation or warranty made in this Agreement unless the parties agree
thereto in writing.

     7.9  Employees.
          --------- 

          (a)  During the period beginning on the date of this Agreement and
ending on the Window Expiration Date ("Buyer's Window"), the Buyer may offer
employment, effective as of the Closing Date, to employees of BHE who are
presently employed principally in connection with the ownership and operation of
the Purchased Assets and whose names and titles are listed individually in a
list previously provided by BHE to the Buyer (all such employees hereinafter
referred to as "Employees"). Notwithstanding the foregoing, any such individual
who, following the date hereof, changes job position of his/her own volition
pursuant to BHE's existing internal job posting procedures and, as a result of
such change, ceases to be employed principally in connection with the ownership
and operation of the Purchased Assets shall not be considered an Employee for
purposes of this Section 7.9, provided, that Buyer may offer employment during
the Buyer's Window to replacement individuals who in general perform the
functions and duties of such departed individual, in which case the Buyer's
Window will extend for an additional 30

                                      45

 
days in respect of such replacement individual (and any such replacement
individual shall be considered an Employee for the purposes of this Section
7.9). To the extent permitted by law, BHE will provide reasonable access to
information (excepting personnel and medical records) and individuals reasonably
necessary to the Buyer in connection with Buyer's consideration of such offers.

          All such offers of employment shall be made in accordance with all
applicable laws and regulations. Each person who becomes employed by the Buyer
pursuant to this Section 7.9 shall be referred to herein as a "Transferred
Employee." Any changes in the terms and conditions of employment of any
Transferred Employee shall be made in accordance with the applicable provisions
of Chapter 32 of Title 35-A ("An Act to Restructure the State's Electric
Industry") (the "Maine Restructuring Law") including 35-A M.R.S.A. (S)3216 and
any rules adopted by the MPUC implementing those statutory requirements,
including Chapter 303.

          Subject to any and all applicable provisions of the Collective
Bargaining Agreement, during the Buyer's Window, Sellers will refrain from
offering post-Closing employment to any of the Employees without the prior
consent of the Buyer, other than those Employees whom the Buyer indicates in
writing it does not intend to hire. Without the prior written consent of BHE,
the Buyer shall not solicit, directly or indirectly, for employment any
employees of BHE or any of its Affiliates at any time beginning on the date
hereof and up to and including the second anniversary of the Closing Date, other
than offers to Employees made during the Buyer's Window.

          Subject to any and all applicable provisions of the Collective
Bargaining Agreement, Sellers shall not, without the prior written consent of
the Buyer, solicit for employment any Employee to whom the Buyer makes an offer
within the Buyer's Window and who becomes a Transferred Employee, at any time
beginning at the end of the Buyer's Window and ending on the second anniversary
of the Closing Date.

          With respect to any Employee who does not become a Transferred
Employee, Sellers shall be responsible for providing such Employee with any
benefits to which such Employee shall become entitled under the Sellers'
Employee Transition Plan, as well as any other termination or severance benefits
to which such Employee may be entitled.

          (b)  The Buyer acknowledges that the Collective Bargaining Agreement
expires on December 31, 1998, and that BHE is obligated to bargain in good faith
with Local 1837 with respect to a replacement or extension of such Agreement,
and Buyer hereby agrees to assume BHE's obligations under the Collective
Bargaining Agreement with respect to any union Transferred Employees as now in
effect and as it may be amended by such replacement or extension. BHE agrees to
keep the Buyer regularly informed of the progress of negotiations with Local
1837 with respect to the amendment or extension of the Collective Bargaining
Agreement. To the extent consistent with its obligation to bargain in good
faith, BHE will use its best efforts to limit the extension of the term of the
Collective Bargaining Agreement as it may apply to Employees in the bargaining
unit to a date not later than December 1, 1999, unless Buyer consents to a later
date, and to limit changes in the Collective Bargaining Agreement that are
applicable to Employees and are adverse to the employer.

                                      46

 
          (c)  For the period commencing on the Closing Date and ending December
31, 2001, the Buyer shall provide all Transferred Employees with total
compensation (including, without limitation, base salary and overtime, bonuses,
and benefits contained in the employee benefit plans, programs and fringe
benefit arrangements of Buyer) which the Buyer in good faith believes is, in the
aggregate, substantially equivalent in value to the total compensation provided
to such employees by BHE immediately prior to the Closing Date (except that
Buyer shall not be required to provide compensation to such employees
corresponding to any bonuses or other incentive compensation paid by BHE).
Nothing herein shall be deemed to guarantee a Transferred Employee continued
employment with the Buyer for any definite period of time.

          (d)  As of the Closing Date, all Transferred Employees shall cease to
participate in the employee welfare benefit plans (as such term is defined in
ERISA) maintained or sponsored by BHE (the "Prior Welfare Plans") and shall, if
applicable, commence to participate in welfare benefit plans of the Buyer or its
Affiliates (the "Replacement Welfare Plans"). The Buyer shall (i) waive all
limitations as to pre-existing condition exclusions and waiting periods with
respect to Transferred Employees under the Replacement Welfare Plans, other
than, but only to the extent of, limitations or waiting periods that were in
effect with respect to such employees under the Prior Welfare Plans and that
have not been satisfied as of the Closing Date, and (ii) provide each
Transferred Employee with credit for any co-payments and deductibles paid prior
to the Closing Date in satisfying any deductible or out-of-pocket requirements
under the Replacement Welfare Plans (on a pro-rata basis in the event of a
difference in plan years).

          (e)  The Buyer shall take any and all necessary action to cause the
trustee of a tax-qualified defined contribution plan of the Buyer or one of its
Affiliates, if requested to do so by a Transferred Employee, to accept a direct
"rollover" of all or a portion of said employee's distribution from any defined
contribution retirement plan of BHE.

          (f)  Buyer shall pay to each Transferred Employee whose employment is
involuntarily terminated by the Buyer or any of its Affiliates subsequent to the
Closing Date and prior to December 31, 2001, except where such employment is
terminated for cause, unless such cause is beyond the control of the Transferred
Employee as in the case of a layoff for lack of work, the "Benefits Required By
Legislative Mandate" (as defined in the Employee Transition Plan of BHE prepared
pursuant to the Maine Restructuring Law (the "Employee Transition Plan")) that
would have been provided to such individual upon such termination by BHE under
the Employee Transition Plan, had such employee remained continuously employed
by BHE and had such individual been eligible under, and covered by, such plan on
the date of such termination; provided however, that no such benefit shall be
required to be paid by the Buyer to any such employee who either received the
Benefits Required By Legislative Mandate or elected to receive the "Enhanced &
Unreduced Accrued Benefit Option" from BHE under (and as defined in) the
Employee Transition Plan.

          (g)  Sellers agree to timely perform and discharge all requirements
under the WARN Act, if any, and under applicable state and local laws and
regulations for the notification of their employees arising from the sale of the
Purchased Assets to the Buyer. After the Closing Date, the Buyer shall be
responsible for performing and discharging all requirements under the WARN Act,
if any, and under applicable state and local laws and regulations for the
notification of its employees with respect to the Purchased Assets.

                                      47

 
          (h)  Subject to the other provisions of this Section 7.9, and except
as specifically provided to the contrary in this Agreement:

               (1)  The Sellers, and not the Buyer, shall be responsible and
          shall assume any and all liability for all compensation, benefits, and
          perquisites of any kind due any Transferred Employee on account of
          employment by the Sellers before the Closing Date, or the termination
          of employment by the Sellers, including, but not limited to,
          continuation of health care coverage pursuant to the health
          continuation coverage provisions of the Consolidated Omnibus Budget
          Reconciliation Act of 1986, as amended ("COBRA") and compliance with
          the Health Insurance Portability and Accountability Act of 1996, as
          amended ("HIPAA"); and

               (2)  The Buyer, and not the Sellers, shall be responsible and
          shall assume any and all liability for all compensation, benefits, and
          perquisites of any kind due any Transferred Employee on account of
          employment by the Buyer on and after the Closing Date, or the
          termination of employment by the Buyer, including, but not limited to,
          continuation of health care coverage pursuant to COBRA and compliance
          with HIPAA.

     7.10 Risk of Loss.
          ------------ 

          (a)  From the date hereof through the Closing Date, all risk of loss
or damage to the property included in the Purchased Assets shall be borne by the
Sellers.

          (b)  If, before the Closing Date, all or any portion of the Purchased
Assets is taken by eminent domain (or is the subject of a pending or (to the
Knowledge of the Sellers) contemplated taking which has not been consummated),
the Sellers shall notify the Buyer promptly in writing of such fact, and Buyer
shall have the option to elect (A) to eliminate the affected Purchased Asset or
group of Purchased Assets and proceed with the Closing with the Purchase Price
being decreased by an amount equal to the aggregate value of the eliminated
Purchased Asset or group of Purchased Assets, (B) to retain the affected
Purchased Asset or group of Purchased Assets and negotiate an adjustment to the
Purchase Price, in which event the Buyer and the Sellers shall negotiate in good
faith to settle the loss resulting from such taking (including, without
limitation, by making a fair and equitable adjustment to the Purchase Price)
and, upon such settlement, proceed with the Closing pursuant to the terms of
this Agreement, or (C) if the aggregate value of the Purchased Asset or group of
Purchased Assets taken by eminent domain exceeds 10% or more of the Purchase
Price, to terminate this Agreement pursuant to Section 10.1(d); provided,
however, that, subject to Section 3.5, Buyer shall not be entitled to terminate
this Agreement if the affected Purchased Asset is solely (1) the Veazie Hydro
Project, or (2) the Bangor-Pacific Interest.

          (c)  If, before the Closing Date, all or any portion of the Purchased
Assets is damaged or destroyed by fire or other casualty, the Sellers shall
notify the Buyer promptly in writing of such fact and, if the Sellers have not
notified the Buyer within thirty (30) days after the occurrence of such damage,
destruction or loss of their intention to cure such damage, destruction or loss
prior to Closing Date (and unless such cure is so effected prior to the Closing

                                      48

 
Date), Buyer shall have the option to elect (A) to eliminate the affected
Purchased Asset or group of Purchased Assets and proceed with the Closing with
the Purchase Price being decreased by an amount equal to the aggregate value of
the eliminated Purchased Asset or group of Purchased Assets, (B) to retain the
affected Purchased Asset or group of Purchased Assets and negotiate an
adjustment to the Purchase Price, in which event the Buyer and the Sellers shall
negotiate in good faith to settle the loss resulting therefrom (including,
without limitation, by making a fair and equitable adjustment to the Purchase
Price), and, upon such settlement, proceed with the Closing pursuant to the
terms of this Agreement, or (C) if the aggregate value of the Purchased Asset or
group of Purchased Assets damaged or destroyed exceeds 10% or more of the
Purchase Price, to terminate this Agreement pursuant to Section 10.1(d);
provided, however, that, subject to Section 3.5, Buyer shall not be entitled to
terminate this Agreement if the affected Purchased Asset is solely (1) the
Veazie Hydro Project, or (2) the Bangor-Pacific Interest.

           (d)  In the case of an adjustment to the Purchase Price pursuant to
paragraph (b) or (c) hereof due to the taking of or damage to a Purchased Asset,
the Maintenance and Capital Expenditure Amount shall be reduced by the amounts
thereof attributable to such assets.

     7.11  Confidential Information.
           ------------------------ 

           (a) All oral and written information (collectively "Information")
disclosed by any party or its representatives, whether before or after the date
hereof, in connection with the transactions contemplated by or the discussions
and negotiations preceding this Agreement, to any other party or its directors,
officers and employees and representatives of its advisors (the persons to whom
such disclosure is permissible being collectively called "Representatives"),
shall (i) be kept confidential by other party and its Representatives, and shall
not be disclosed by such other party and its Representatives except as otherwise
provided in this Agreement, (ii) not be used by any such other persons except as
contemplated by this Agreement, and (iii) be treated with the same degree of
care used in protecting its own confidential and proprietary information.

           (b) Each party hereto will inform its Representatives of the
confidential nature of the other party's Information and will be responsible for
any breach of this Section 7.11 by its Representatives.

           (c) If any party is requested or required (by the terms of a
subpoena, order, civil investigative demand or other similar process or other
written request issued by a court of competent jurisdiction or by a Federal,
state or local governmental body or agency) to disclose any Information of the
other party (or any of the terms, conditions or other facts with respect to the
transactions contemplated by this Agreement), the obligated party shall (i)
provide the other party with prompt notice of such request(s) and the documents
requested so that the other party may seek an appropriate protective order
and/or waive the obligated party's compliance with the provisions of this
Section 7.11, and (ii) take such legally available steps as the other party may
reasonably request, to resist or narrow such request. If, in the absence of a
protective order or the receipt of a waiver hereunder the obligated party is
nonetheless, in the reasonable opinion of its legal counsel, compelled to
disclose Information of the other party pursuant to any regulatory or judicial
proceeding, the obligated party may disclose such Information to such tribunal
without liability hereunder; provided, however, that the obligated party shall
give the other party written notice of Information to be so disclosed as far in
advance of its disclosure as is

                                      49

 
practicable, shall furnish only that portion of the Information which is legally
required, and shall request an order or other reliable assurance that
confidential treatment will be accorded to such portions of the Information
required to be disclosed as the affected party designates.

           (d) The term "Information" does not include any information which (i)
becomes generally available to and known by the public (other than as a result
of a unilateral disclosure directly or indirectly made by the recipient party or
its Representatives), (ii) becomes available to the recipient party on a non-
confidential basis from a source other than the disclosing party or its
Representatives, provided that such source is not and was not bound by a
confidentiality agreement with or other obligation of secrecy to the disclosing
party, or (iii) which in the opinion of counsel to the disclosing party is
required to be disclosed by federal securities laws, provided that the
disclosing party shall consult with the other parties hereto as to the content
of any such disclosure prior to its occurrence.

           (e) From the date hereof through the Closing Date, Buyer shall have
the right to disclose Information of Sellers with respect to the Purchased
Assets to financing parties and their respective representatives in connection
with financing the transactions contemplated by this Agreement and to third
parties in connection with planning for operations of the Purchased Assets
following the Closing Date, provided that any such disclosure is made pursuant
to confidentiality obligations equivalent to those provided in this Section
7.11. The Buyer shall be responsible for any breach of this Section 7.11(e) by
any such third party.

           (f) If this Agreement is terminated in accordance with its terms, the
recipient party will return promptly to the disclosing party all copies,
extracts or other reproductions in whole or in part of the disclosing party's
Information in the recipient party's possession or in the possession of its
Representatives, and the recipient party will destroy all copies of any
memoranda, notes, analyses, compilations, studies or other documents prepared by
the recipient party or for the recipient party's use based on, containing or
reflecting any Information. Such destruction shall, if requested, be certified
in writing to the disclosing party by an authorized officer of the recipient
party supervising such destruction.

           (g) The parties agree that each shall be entitled to equitable
relief, including injunction and specific performance, in the event of any
breach of the provisions of this Section 7.11, in addition to all other remedies
available to such party at law or in equity.

           (h) This Section 7.11 supersedes the correlative provisions of the
Confidentiality Agreement, which agreement is of no further force and effect,
provided that Information disclosed by one party to the other party hereto prior
to the date hereof shall be Information for all purposes of this Section 7.11.

     7.12  Observation, Inspection and Participation.
           ----------------------------------------- 

           (a) Between the date of this Agreement and the Closing Date, the
Buyer shall be entitled to have a reasonable number of representatives, all of
whom shall be employees of the Buyer or its Affiliates unless otherwise agreed
by BHE in each instance ("Site Representatives") at any of the Purchased Assets,
on a full or part time basis (whether on site or off site), as determined by the
Buyer; provided, however, that (A) the presence and activities of the Site

                                      50

 
Representatives shall be conducted in a manner as not to interfere unreasonably
with the operation of the Purchased Assets, or with the activities of the
Sellers not related to the Purchased Assets and (B) the Site Representatives
shall not have access to any information that is unavailable pursuant to Section
7.2. Reasonable office space and facilities shall be made available by the
Sellers to such Site Representatives. Each Site Representative shall have the
right to review budgets and expenditures, audit records (except for personnel
and medical records unless required by law), inspect equipment, advise on
repairs required for equipment, review permits, review the progress of outages,
review maintenance and operating practices and otherwise observe all activities
at the above mentioned facilities in each case to the extent related to the
Purchased Assets or the conduct of the Business and subject to the limitations
contained in Section 7.12(b).

           (b) Between the date of this Agreement and the Closing Date, the
Sellers shall exercise their reasonable best efforts to invite Site
Representatives to attend meetings (whether internal or with third parties) in
which the Sellers participate and which relate specifically to the physical
operation or maintenance of the Purchased Assets or the conduct of the Business;
provided, however, that such obligation shall not extend to (i) meetings of the
boards of directors, or any committees thereof, of any of the Sellers or their
Affiliates, (ii) meetings with governmental or regulatory authorities which are
not open to the public, provided that promptly following each such a meeting
Sellers shall inform the Buyer of the discussions at such meeting as they relate
to the Purchased Assets, (iii) meetings as to which any participant not
affiliated with any of the Sellers (or any of their Affiliates), at its own
initiative, requests that Site Representatives not attend, provided that
promptly following each such meeting Sellers shall inform the Buyer of the
discussions at such meeting as they relate to the Purchased Assets, (iv)
meetings of employees of the Sellers relating to the preparation of the
Separation Document, (v) meetings with counsel, or (vi) meetings the subject
matter of which, in the Sellers' reasonable judgment, if disclosed to the Buyer,
would likely be detrimental to the Sellers (including, without limitation,
information relating to the Sellers' proposed business activities following the
Closing Date or to contractual or other matters as to which the interests of the
Sellers and the Buyer may diverge). Site Representatives shall also be entitled
to consult with the Sellers and make recommendations as to all activities
relating to the management, operation, maintenance, construction, renewal,
addition, replacement, modification and disposal of the Purchased Assets or the
conduct of the Business, including, without limitation, applications for
authorizations, permits and licenses, and fuel procurement and transportation.

           (c) The Buyer shall exercise its reasonable best efforts to invite
designated representatives of the Sellers to attend all meetings between the
date of this Agreement and the Closing Date with third parties in which the
Buyer participates and which relate specifically to any proceedings before the
FERC with respect to this Agreement, the Interconnection Agreement or the
Transitional Power Sales Agreement or the transactions contemplated hereby or
thereby.

     7.13  Delivery of Books and Records, etc.; Removal of Property. On or prior
           --------------------------------------------------------
to the Closing Date, Sellers will deliver or make available to Buyer at the
locations of the Purchased Assets all of the books and records and other such
assets constituting a part of the Purchased Assets as are in Sellers' possession
at other locations and, if at any time after the Closing Date, Sellers discover
in their possession or under their control any other such books and records,

                                      51

 
Sellers will promptly delivery such books and records to the Buyer. Within a
reasonable time after the Closing Date and subject to the Easements and except
as contemplated by the Separation Document, Sellers shall remove all assets not
being sold to the Buyer pursuant to this Agreement from the Real Estate. Such
removal shall be at the sole cost and risk of Sellers, including risk of loss
and damage to such assets and to the Purchased Assets conveyed to the Buyer
pursuant to this Agreement.

     7.14  Millenium Compliance. Sellers shall use their best efforts to assure
           -------------------- 
that no later than October 1, 1999, all proprietary technology and third party
proprietary technology which comprise a part of the Purchased Assets (technology
so utilized is collectively referred to as "Technology") is made "Century Date
Compliant." Any such Technology is deemed to be Century Date Compliant if:

           (a) the functions, calculations, and other computing processes of the
Technology (collectively "Processes") perform in a consistent manner and
correctly track and account for dates and passage of time, regardless of the
date in time on which the Processes are actually performed and regardless of the
date on which data was input into the product, whether before, on, or after
January 1, 2000  and whether or not the dates are affected by leap years;

           (b) the Technology accepts, calculates, compares, sorts, extracts,
sequences, and otherwise processes date inputs and date values, and returns and
displays date values in a consistent manner and correctly tracks and accounts
for dates and the passage of time, regardless of the dates used, whether before,
on or after January 1, 2000;

           (c) the Technology functions without interruptions caused by the date
in time on which the Processes are actually performed or by the date input to
the system, whether before, on or after January 1, 2000;

           (d) the Technology accepts and responds to year input in a manner
that resolves any ambiguities as to century in a defined and predetermined and
appropriate manner; and

           (e) the Technology stores and displays date information in ways that
are unambiguous as to the determination of the century.

     If, after October 1, 1999, any such Technology is discovered not to be
Century Date Compliant, Sellers shall reimburse Buyer for all reasonable costs
associated with making the Technology Century Date Compliant and shall indemnify

          or other jurisdiction in which it is qualified to do business as a
          foreign corporation by virtue of owning the Purchased Assets or

          binding obligations of the Sellers, enforceable against the Sellers in
          accordance with their terms, except (A) that such enforcement may be
          subject to bankruptcy, insolvency, reorganization, moratorium or other

          defenses and to the discretion of the court before which any
          proceeding therefor may be brought;

              (3) the execution, delivery and performance of this Agreement and
          the Ancillary Agreements by the Sellers will not constitute a
          violation of the Articles of Incorporation or Bylaws, as currently in
          effect, of any Seller;

              (4) the Bill of Sale and other documents described in Section 4.3

     affect the benefits to the Sellers under this Agreement or the transactions
     contemplated hereby;

          (e) All corporate and other proceedings to be taken by the Buyer in

however, that, in the case of any Indemnifiable Loss arising under clause (i) or
- -------

Indemnifiable Losses exceed ten percent (10%) of the Purchase Price, and (Z) the
foregoing limitations on Sellers' indemnity shall not apply to the extent the
Certain Indemnifiable Loss results from any successor liability of Buyer arising
out of a failure of Bangor-Pacific to file any Tax Return required to be filed
by it prior to the Closing, or the failure of Sellers to file any Tax Return or
pay any Tax required to be filed or paid by them under this Agreement, and
provided, further, that in the case of any Indemnifiable Loss relating to the
- --------  -------                                                            
Excluded Liabilities of Sellers described in Section 2.4(vi) (hereinafter,
"Seller Indemnified Environmental Losses"), (1) such indemnification shall be

Sellers no later than the third anniversary of the Closing Date, (2) no amounts
shall be due and payable to the extent that the sum of such Seller Indemnified
Environmental Losses plus the Certain Indemnifiable Losses is equal to $500,000
or less and (3) in no event shall the aggregate amount of all payments made by
the Sellers with respect to such Seller Indemnified Environmental Losses exceed
$20 million.

          (b) The Buyer will indemnify, defend and hold harmless the Sellers and
their affiliates and their respective directors, officers, employees, agents and
representatives ("Sellers Group") from and against any and all Indemnifiable
Losses asserted against or suffered by the Sellers Group relating to, resulting
from or arising out of (i) any breach of any representation or warranty of the

agreement of the Buyer set forth in Sections 7.5, 7.6(a), 7.6(d), 7.10 or 7.12,
(iii) any breach of any other covenant or agreement of the Buyer contained in
this Agreement, any schedule hereto, or any certificate delivered by or on
behalf of Buyer in connection herewith, or (iv) the Assumed Liabilities,
provided, however, that in the case of any Indemnifiable Loss arising under
- --------  -------

amount 

                                      58

 
of all payments made by the Buyer with respect to such Indemnifiable Losses
exceed ten percent (10%) of the Purchase Price.

          (c) Any Person entitled to receive indemnification under this
Agreement (an "Indemnitee") having a claim under these indemnification
provisions shall make a good faith effort to recover all losses, damages, costs
and expenses from insurers of such Indemnitee under applicable insurance
policies so as to reduce the amount of any Indemnifiable Loss hereunder. The
amount of any Indemnifiable Loss shall be reduced (i) to the extent that the
Indemnitee receives any insurance proceeds with respect to an Indemnifiable Loss
and (ii) to take into account any net Tax benefit recognized by the Indemnitee
arising from the recognition of the Indemnifiable Loss and any payment actually
received with respect to an Indemnifiable Loss.

          (d) The expiration, termination or extinguishment of any
representation, warranty, covenant or agreement shall not affect the parties'
obligations under this Section 9.1 if the Indemnitee provided the person
required to provide indemnification under this Agreement (the "Indemnifying
Party") with proper notice of the claim or event for which indemnification is
sought prior to such expiration, termination or extinguishment.

          (e) Other than as provided in Section 10.2 hereof, the rights and
remedies of the Sellers and the Buyer under this Article IX are exclusive and in
lieu of any and all other rights and remedies which the Sellers and the Buyer
may have under this Agreement or otherwise for monetary relief with respect to
(i) any breach or failure to perform any representation, warranty, covenant or
agreement set forth in this Agreement, any schedule hereto, or any certificate
delivered by or on behalf of Sellers or Buyer in connection herewith or (ii) the
Assumed Liabilities or the Excluded Liabilities, as the case may be.

          The rights and obligations of indemnification under this Section 9.1
shall not be limited or subject to set-off based on any violation or alleged
violation of any obligation under this Agreement or otherwise, including but not
limited to breach or alleged breach by the Indemnitee of any representation,
warranty, covenant or agreement contained in this Agreement.

     9.2  Defense of Claims.
          ----------------- 

          (a) If any Indemnitee receives notice of the assertion of any claim or
of the commencement of any claim, action, or proceeding made or brought by any
Person who is not a party to this Agreement or any Affiliate of a party to this
Agreement (a "Third Party Claim") with respect to which indemnification is to be
sought from an Indemnifying Party, the Indemnitee will give such Indemnifying
Party prompt written notice thereof, but in any event not later than twenty (20)
days after the Indemnitee's receipt of notice of such Third Party Claim.  Such
notice shall describe the nature of the Third Party Claim in reasonable detail
(including a copy of the Third Party Claim if made in writing) and will indicate
the estimated amount, if practicable, of the Indemnifiable Loss that has been or
may be sustained by the Indemnitee.  The Indemnifying Party will have the right,
by giving written notice to the Indemnitee as provided below, to elect to assume
the defense of any Third Party Claim at such Indemnifying Party's own expense
and by such Indemnifying Party's own counsel, by all appropriate proceedings,
which proceedings will be diligently prosecuted, and the Indemnitee will upon
request of an Indemnifying Party cooperate in good faith in such defense at the
Indemnifying Party's expense.  

                                      59

 
If the Indemnifying Party assumes the defense of any Third Party Claim, the
Indemnified Party is hereby authorized (but not obligated), at the expense of
the Indemnified Party, to file any motion, answer or other pleading and to take
any other action which the Indemnified Party deems necessary or appropriate to
protect the Indemnified Party's interests, provided that such action is not
prejudicial to the Indemnifying Party's defense in any material respect.
Notwithstanding the assumption of defense by the Indemnifying Party, the
Indemnitee may take over the control of the defense or settlement of a Third
Party Claim at any time if it irrevocably waives its right to indemnity with
respect to such Third Party Claim.

          (b) The Indemnifying Party will have a period of fifteen (15) days
after an Indemnitee provides written notice to the Indemnifying Party of any
Third Party Claim within which to notify the Indemnitee in writing that (i) the
Indemnifying Party disputes liability to the Indemnitee hereunder with respect
to the Third Party Claim and, if so, the basis for the dispute, and (ii) if the
Indemnifying Party does not dispute liability, whether or not the Indemnifying
Party has elected to assume the defense of such Third Party Claim as provided in
the last sentence of Section 9.2(a).  If the Indemnifying Party has assumed the
defense, it will not be liable for any legal expenses subsequently incurred by
the Indemnitee in connection with the defense thereof.  Without the prior
written consent of the Indemnitee in its sole discretion, the Indemnifying Party
will not enter into any settlement of any Third Party Claim which would lead to
liability or create any financial or other obligation on the part of the
Indemnitee for which the Indemnitee does not simultaneously receive full
indemnification or which would fail to result in the Indemnitee receiving a
release of the Indemnitee reasonably satisfactory to it.  If the Indemnifying
Party fails to assume the defense, assumes the defense but fails to diligently
prosecute it, or fails to give any notice when required hereunder, then the
Indemnitee will have the right to defend against such Third Party Claim, at the
sole cost and expense of the Indemnifying Party, and, if requested by the
Indemnitee, the Indemnifying Party will at the sole cost and expense of the
Indemnifying Party, cooperate with the Indemnitee and its counsel in such
defense.  If the Indemnifying Party disputes its liability for any portion of
such Third Party Claim, the Indemnitee will be free to seek enforcement of its
rights, if any, to indemnification under this Agreement.

          (c) Any claim by an Indemnitee on account of an Indemnifiable Loss
which does not result from a Third Party Claim (a "Direct Claim") will be
asserted by giving the Indemnifying Party written notice thereof prior to the
expiration of the indemnification notice period, stating the nature of such
claim in reasonable detail and indicating the estimated amount, if practicable,
but in any event not later than twenty (20) days after the Indemnitee becomes
aware of such Direct Claim, and the Indemnifying Party will have a period of
thirty (30) days within which to respond to such Direct Claim, specifying the
portion of the Direct Claim that is disputed and the basis for such position.
If Indemnifying Party does not respond within such thirty (30) day period the
Indemnifying Party will be deemed to have accepted such claim.  If the
Indemnifying Party responds within such thirty (30) day period, the Indemnifying
Party will be deemed to have accepted and be liable for payment of the
undisputed portion of such claim, if any, on demand.  If the Indemnifying Party
rejects any portion of such claim, the Indemnitee will be free to seek
enforcement of its rights to indemnification under this Agreement.

          (d) If the amount of any Indemnifiable Loss, at any time subsequent to
the making of an indemnity payment in respect thereof, is reduced by recovery,
settlement or 

                                      60

 
otherwise under or pursuant to any insurance coverage, or pursuant to any claim,
recovery, settlement or payment by or against any other entity, the amount of
such reduction, less any costs, expenses or premiums incurred in connection
therewith, will promptly be repaid by the Indemnitee to the Indemnifying Party.
Upon making any indemnity payment, the Indemnifying Party will, to the extent of
such indemnity payment, be subrogated to all rights of the Indemnitee against
any third party in respect of the Indemnifiable Loss to which the indemnity
payment relates; provided, however, that (i) the Indemnifying Party will then be
in compliance with its obligations under this Agreement in respect of such
Indemnifiable Loss and (ii) until the Indemnitee recovers full payment of its
Indemnifiable Loss, any and all claims of the Indemnifying Party against any
such third party on account of said indemnity payment is hereby made expressly
subordinated and subjected in right of payment to the Indemnitee's rights
against such third party. Without limiting the generality or effect of any other
provision hereof, each such Indemnitee and Indemnifying Party will duly execute
upon request all instruments reasonably necessary to evidence and perfect the
above-described subrogation and subordination rights. Nothing in this Section
9.2(d) shall be construed to require any party hereto to obtain or maintain any
insurance coverage. The rights contained herein shall not be duplicative of any
reductions effected pursuant to Section 9.1(c) hereof.

          (e) Subject to clauses (X) and (1) of the provisos to Section 9.1(a)
and clause (X) of the proviso to Section 9.1(b) hereof, a failure to give timely
notice as provided in this Section 9.2 will not affect the rights or obligations
of any party hereunder except if, and only to the extent that, as a result of
such failure, the party which was entitled to receive such notice was actually
prejudiced as a result of such failure.

          (f) During the three-year period following the Closing Date, if the
Buyer acquires Knowledge of an event, condition or circumstance described in
Sections 2.3(a)(v), 2.4(v) or 2.4(vi) of this Agreement, including, without
limitation, any event, act, omission, loss, circumstance, injury, damage,
Release or occurrence (an "Environmental Condition"), the Buyer shall give
prompt written notice to BHE of such Environmental Condition regardless of
whether it is a matter for which Buyer is indemnified by Sellers under this
Agreement (provided that subsection (e) of this Section shall apply to such
notice).  Excluded from this notice requirement are Environmental Conditions
existing as of the date of this Agreement that have been disclosed to the Buyer
by the Sellers.  Such notice shall describe the Environmental Condition in
reasonable detail and include a copy of any written documentation in Buyer's (or
its agents') possession regarding the Environmental Condition.  Until Sellers
shall no longer have any indemnification obligations with respect to Seller
Indemnified Environmental Losses under Section 9.1(a) hereof, if either (i) the
notice states that such Environmental Condition is a matter with respect to
which Buyer or any member of the Buyer Group is seeking or may seek
indemnification from Sellers hereunder, or (ii) BHE otherwise reasonably
concludes that the existence of or the potential remediation of such
Environmental Condition could result in a Seller Indemnified Environmental Loss,
then, in addition to the rights set forth elsewhere in this Section 9.2, BHE
shall have the right, at its sole cost and expense, to conduct and control any
investigation and/or remediation ("Remediation") relating to or arising out of
the Environmental Condition.

          If Sellers conduct the Remediation,

                                      61

 
          (1) Buyer shall have the right to participate in the planning and
     design of any such Remediation and the right to participate in any meetings
     with, hearings before or other sessions with any governmental body
     regarding the Remediation;

          (2) Sellers will coordinate the schedule of the Remediation with Buyer
     so that disruptions of operation of the affected facilities will be
     minimized;

          (3) Buyer will cooperate with Sellers to enable them to conduct the
     Remediation in a reasonably timely manner, including without limitation
     affording Sellers and their agents reasonable access to the property to be
     remediated, provided that such cooperation need not include the payment of
     money or any other financial accommodation;

          (4) in case clause (ii) of this subsection (f) is applicable, Sellers
     will obtain the prior written approval of the Buyer, which consent will not
     be withheld unreasonably, for any consultant or contract or retained by
     Sellers to design or implement the Remediation;

          (5) Sellers will conduct the Remediation in compliance with all
     applicable Environmental Laws;

          (6) Sellers will use their reasonable efforts to complete such
     Remediation in a timely and professional manner;

          (7) in case clause (ii) of this subsection (f) is applicable, Sellers
     will not agree to or select any Remediation plan without the consent of
     Buyer to such plan, which shall not be withheld unreasonably or delayed;

          (8) Sellers will not agree to or select any Remediation plan that
     imposes any additional obligations on Buyer, including the obligation to
     sign manifests or obtain permits, without the prior written consent of the
     Buyer.  If Buyer agrees in writing to a Remediation that imposes additional
     obligations on Buyer, and Sellers then fail, in the reasonable opinion of
     Buyer after notice from Buyer, to implement the Remediation in a manner
     which will complete the Remediation in a reasonably timely manner and in
     accordance with Environmental Laws, the Buyer may give written notice of
     such failure to the Sellers and, if after giving such notice, Sellers shall
     not have addressed Buyer's concerns in a satisfactory manner within thirty
     (30) days, Buyer may assume control of the Remediation and implement and
     complete such Remediation at the expense of the Sellers (subject to the
     ultimate determination under this Article IX of responsibility for such
     expenses).  Sellers shall provide the Buyer copies of any study, plan or
     report associated with the Remediation at least thirty (30) days before it
     is submitted to any governmental body and shall provide Buyer copies of all
     reports, plans and correspondence submitted to a governmental body.  In
     addition, Sellers shall provide Buyer seven days' notice (or shall provide
     Buyer notice as soon as practical if seven days' notice is not practical)
     of any meetings with, hearings before or other sessions with any
     governmental body with respect to the Remediation; and

          (9) Sellers shall be responsible for any violation or alleged
     violation of Environmental Law, and any loss of life, injury to persons or
     property or damage to natural resources caused (or allegedly caused), by
     (i) negligent acts or omissions by the 

                                      62

 
     Sellers in connection with Remediation conducted by Sellers at any of the
     Purchased Assets; (ii) acts or omissions by the Sellers at any of the
     Purchased Assets in connection with Remediation conducted by Sellers which
     cause a condition not in violation of Environmental Law or not in need of
     remediation under Environmental Law to be in violation of Environmental Law
     or in need of remediation under Environmental Law (including, without
     limitation, the Release or destabilization of Hazardous Substances which
     are in a stable or contained state and are in compliance with all
     applicable Environmental Laws) in connection with Remediation conducted by
     Sellers; or (iii) negligent acts or omissions by the Sellers in connection
     with Remediation conducted by Sellers at any of the Purchased Assets that
     exacerbate or aggravate any condition in violation of Environmental Law or
     in need of remediation under Environmental Law, to the extent of any such
     negligent exacerbation or aggravation; provided, that the mere discovery or
     failure to discover in connection with Remediation conducted by Sellers by
     the Sellers of a violation of Environmental Law or a condition in need of
     remediation under Environmental Law shall not in and of itself subject
     Sellers to liability under this subsection (9).

          Buyer acknowledges that BHE has requested that the MDEP review the
Milford Project pursuant to the Voluntary Response Action Program ("VRAP"), 38
M.R.S.A. (S)343-E and agrees that BHE shall have the right to continue to
prosecute such VRAP application after the Closing.  BHE agrees to indemnify and
hold harmless Buyer from any costs, expenses or liabilities which may arise from
the completion of the VRAP process.

                                                   --------

               --------  -------                                              
Agreement the conditions to the Closing set forth in Section 8.1(c) shall not

or shall be capable of being fulfilled, then the date referred to above shall be

           (c) This Agreement may be terminated by either the Sellers or the

enjoining or otherwise prohibiting the Closing, and such order, judgment or
decree shall have become final and nonappealable or (iii) any statute, rule or
regulation shall have been enacted by any state or Federal government or
governmental agency in the United States which prohibits the consummation of the
Closing.

           (d) This Agreement may be terminated by the Buyer in accordance with
Section 3.5 or Section 7.10.

     10.2  Procedure and Effect of Termination.  In the event of termination of
           -----------------------------------

or both of the parties pursuant to Section 10.1, written notice thereof shall

this Agreement, to the extent practicable, shall be withdrawn from the agency or
other person to which they were made.

     Notwithstanding any other term or provision of this Agreement or the other
documents delivered pursuant to this Agreement, each of the parties hereby
agrees that no officers, directors, employees, agents or attorneys of such party

special, indirect, punitive or incidental damages that may be incurred by any

                           MISCELLANEOUS PROVISIONS
                           ------------------------

     11.1  Amendment and Modification.  Subject to applicable law, this
           -------------------------- 
Agreement may be amended, modified or supplemented only by written agreement of
the Sellers and the Buyer.

     11.2  Waiver of Compliance; Consents.  Except as otherwise provided in this
           ------------------------------ 
Agreement, any failure of any of the parties to comply with any obligation,
covenant, agreement or condition herein may be waived by the party entitled to
the benefits thereof only by a written instrument signed by the party granting
such waiver, but such waiver or failure to insist upon

                                      64

 
strict compliance with such obligation, covenant, agreement or condition shall
not operate as a waiver of, or estoppel with respect to, any subsequent or other
failure.

           -----------

     11.5  Assignment.  This Agreement and all of the provisions hereof shall be
           ---------- 
binding upon and inure to the benefit of the parties hereto and their respective
successors and permitted assigns, but neither this Agreement nor any of the
rights, interests or obligations hereunder shall be assigned by any party
hereto, including by operation of law, without the prior written consent of the
other party, nor is this Agreement intended to confer upon any other Person
except the parties hereto any rights or remedies hereunder; provided, however,
that the Buyer may assign, with the Sellers' consent, which shall not be
unreasonably withheld, any or all of its rights, interests and obligations
hereunder to one or more of its Affiliates or, without any consent by Sellers,
to one or more of the direct or indirect wholly-owned Subsidiaries of PP&L
Global, Inc. (in either which case the Buyer shall nonetheless remain jointly
and severally responsible for the performance of all such obligations) so long

consummation of the sale of the Purchased Assets and so long as the Parent's
obligations under the Equity Contribution Agreement extend directly to such
Affiliate or wholly-owned subsidiary. Notwithstanding the foregoing, the rights
and obligations of the Sellers (or any of them) pursuant to this Agreement may,
with the Buyer's consent, which shall not be unreasonably withheld, delayed or
conditioned, be assigned to, and assumed by, such entity or entities to which

might otherwise govern under applicable Maine principles of conflicts of law) as
to all matters, including but not limited to matters of validity, construction,
effect, performance and remedies. Any and all disputes arising out of or in
connection with this Agreement shall be adjudicated in the Federal or state
courts located in the State of Maine, to whose jurisdiction the parties hereby
irrevocably submit for such purposes. The parties agree to perform their duties
pursuant to this Agreement and the Ancillary Agreements in good faith and in a
commercially reasonable manner.

     11.7  Counterparts.  This Agreement may be executed in two or more
           ------------ 
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

     11.8  Interpretation.  The Article and Section headings contained in this
           -------------- 
Agreement are solely for the purpose of reference, are not part of the agreement
of the parties and shall not in any way affect the meaning or interpretation of
this Agreement. Neither party shall be deemed to have been the drafter of this
Agreement, which is the product of detailed, arm's length negotiations between
the parties and their respective counsel.

                                      66

 
     11.9  Schedules and Exhibits.  All Exhibits and Schedules referred to
           ---------------------- 
herein are intended to be and hereby are specifically made a part of this
Agreement. Any matters described or referred to in any Schedule shall be deemed
included in any other relevant Schedule, irrespective of whether any express
incorporation by reference is made therein to the extent it is readily apparent
that the matter to be disclosed should be included in the other schedule.

     11.10  Entire Agreement.  This Agreement including the Exhibits, Schedules,
            ---------------- 
documents, certificates and instruments referred to herein, embodies the entire
agreement and understanding of the parties hereto in respect of the transactions
contemplated by this Agreement and supersedes any and all prior oral or written
expressions, understandings or agreements between or among the parties with
respect thereto. There are no restrictions, promises, representations,
warranties, covenants or undertakings, other than those expressly set forth or
referred to herein or therein. It is expressly acknowledged and agreed that,
other than as expressly set forth in this Agreement, there are no restrictions,
promises, representations, warranties, covenants or undertakings contained in
any material made available to the Buyer pursuant to the terms of Section 7.11
(including without limitation the Offering Memorandum, dated April 1998, the
reference manuals relating to the Purchased Assets, any other supplemental
information or responses to data requests, or materials received from or
reviewed at the Sellers' document center, in each case made available to the
Buyer by the Sellers or Reed Consulting Group, Inc.).

     11.11  No Punitive or Consequential Damages.  Notwithstanding anything to
            ------------------------------------ 
the contrary contained in this Agreement in Article IX or otherwise, except to
the extent provided in Section 9.1(a) or (b) with respect to Indemnifiable
Losses consisting of claims of third parties, no party or its Affiliates shall
seek or be liable for any punitive or consequential damages, including, but not
limited to, loss of revenue or income, or loss of business reputation or
opportunity relating to any breach or alleged breach of this Agreement.

     11.12  Parties' Knowledge of Others' Breach.  Buyer shall not be entitled
            ------------------------------------ 
to assert that the condition to Buyer's obligation set forth in Section
8.2(b)(i) of this Agreement is not satisfied due to a breach by Sellers of any
of their representation and warranties of which Buyer solely has Knowledge.
Sellers shall not be entitled to assert that the condition to Sellers'
obligations set forth in Section 8.3(b)(i) of this Agreement is not satisfied
due to a breach by Buyer of any of its representation and warranties of which
Sellers solely have Knowledge.

                                      67

 
     IN WITNESS WHEREOF, the Sellers and the Buyer have caused this agreement to
be signed by their respective duly authorized officers as of the date first
above written.
