     been obligated to contribute to at any time ("ERISA Affiliate Plan");

     under Title IV of ERISA; (B) relating to a multiemployer plan; (C) with

Liabilities, and the Buyer agrees promptly to notify the Sellers of the
institution or commencement of any of the foregoing if and when Buyer obtains
knowledge thereof, and to cooperate fully, at Sellers' sole cost and expense,
with the Sellers in connection therewith; provided, that all such remediation
activities conducted after the Closing Date shall be coordinated with the
Buyer and conducted in a manner as not to interfere unreasonably with Buyer's
activities at the Purchased Assets (including, without limitation, Buyer's
operation and maintenance of the Purchased Assets).

                              PURCHASE PRICE

     3.1  Purchase Price.  The purchase price for the Purchased Assets shall
be an amount equal to the sum of (a) $37,425,000, and (b) the Adjustment
Amount (collectively, the "Purchase Price").

     3.2  Purchase Price Adjustment.

     (a)  Within ten (10) Business Days after the Closing, the Sellers 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 all fuel inventory (FERC account no. 151)
used at or in connection with the Purchased Assets except the Wyman Station
(the "Inventory Adjustment Amount"), and (ii) the Maintenance and Capital
Expenditures Amount.  The Inventory Adjustment Amount and the Maintenance and
Capital Expenditures Amount for the Closing are referred to collectively as
the "Adjustment Amount."  The Inventory Adjustment Amount will be based on a
fuel inventory survey conducted within five days prior to the Closing Date
consistent with current inventory procedures of the Sellers (the "Inventory
Survey").  The Sellers will permit an employee, or representative, of the
Buyer to observe the 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 such Adjustment Statement.  The Buyer
agrees to cooperate with the Sellers in connection with the preparation of the
Adjustment Statement and related information, and shall provide to the Sellers
such books, records and information as may be reasonably requested from time
to time.

     (b)  Within ten (10) Business Days after the Buyer's receipt of the
Adjustment Statement, the Buyer shall pay to MPS on behalf of the Sellers an
amount equal to the Adjustment Amount.

     (c)  The Purchase Price reflects Buyer's intent to use the diesel
generating facilities that are included within the Caribou Station on a
regular basis.  Nevertheless, the permit that governs the discharge of cooling
water from those diesel generating facilities includes limits that inhibit
such use during periods of low water flow and warm weather.  MPS agrees that,
unless MPS is able, prior to the Closing Date, to obtain modifications to such
permit that would allow Buyer to use such facilities without such an
inhibition, such modifications to be reasonably satisfactory to Buyer, then
the Purchase Price shall be reduced by One Hundred Thousand Dollars
($100,000).
 
     3.3  Allocation of Purchase Price and Assumed Obligations.  The Buyer and
the Sellers shall use their good faith best efforts to agree upon an

                                 ARTICLE V

               REPRESENTATIONS AND WARRANTIES OF THE SELLERS

     Each of the Sellers, for itself, represents and warrants to the Buyer as
follows, as of the date hereof and on and as of the Closing Date: 

     5.1  Organization; Qualification.  MPS is a corporation duly organized,
validly existing and in good standing under the laws of the State of Maine and
has all requisite corporate power and authority to own, lease, and operate its
properties and to carry on its business as is now being conducted.  MNB is a
corporation duly organized, validly existing and in good standing under the
laws of the Province of New Brunswick, Canada and has all requisite corporate
power and authority to own, lease, and operate its properties and to carry on
its business as is now being conducted.  MPS owns directly 100% of the issued
and outstanding capital stock of MNB.  The Sellers are duly qualified or
licensed to do business as foreign corporations and are in good standing in
each jurisdiction in which the property owned, leased or operated by them or
the nature of the business conducted by them makes such qualification
necessary, except in each case in those jurisdictions where the failure to be
so duly qualified or licensed and in good standing would not create a Material
Adverse Effect.  The states, provinces, and other jurisdictions in which the
Sellers are qualified or licensed to do business are listed in Schedule 5.1.

     5.2  Authority Relative to this Agreement.  Each of the Sellers has full
corporate power and authority to execute and deliver this Agreement and each
of the other Closing Documents to which it is a party and to consummate the
transactions contemplated hereby and thereby.  The execution and delivery by
each Seller of this Agreement and each of the other Closing Documents to which
it is a party and the consummation of the transactions contemplated hereby and
thereby have been duly and validly authorized by the Board of Directors of MPS
and by the Board of Directors of MNB and its sole shareholder, and no other
corporate proceedings on the part of either Seller are necessary to authorize
this Agreement or any of the other Closing Documents to which it is a party or
to consummate the transactions contemplated hereby or thereby.  No notice to,
meeting of, action by, or approval of the shareholders of MPS is necessary to
authorize the execution and delivery of this Agreement or any of the other
Closing Documents to which MPS is a party, or to consummate the transactions
contemplated hereby or thereby.  No preferred stock of MPS is issued and
outstanding.  Each of this Agreement and the other Closing Documents to which
either Seller is a party has been duly and validly executed and delivered by
such Seller, and assuming that each of this Agreement and such other Closing
Documents constitutes a valid and binding agreement of the Buyer, subject to
the receipt of the Sellers Required Regulatory Approvals and the Buyer
Required Regulatory Approvals, constitutes a valid and binding agreement of
such Seller enforceable against such Seller in accordance with its terms,
except that such enforceability may be limited by applicable bankruptcy,
insolvency, moratorium or other similar laws affecting or relating to
enforcement of creditors' rights generally and by general principles of
equity.

     (a)  Except as set forth in Schedule 5.3, and other than obtaining the

Approvals, neither the execution and delivery of this Agreement and the other
Closing Documents by the Sellers nor the consummation of the transactions
contemplated hereby or thereby (including, without limitation, the sale by the
Sellers of the Purchased Assets pursuant to this Agreement and the other
Closing Documents) will (i) conflict with or result in any breach of any
provision of the respective organizational documents or bylaws of the Sellers,
(ii) require any consent, approval, authorization or permit of, or filing with
or notification to, any governmental or regulatory authority, except (x) where
the failure to obtain such consent, approval, authorization or permit, or to
make such filing or notification, would not, individually or in the aggregate,
create a Material Adverse Effect or (y) for those requirements which become
applicable to the Sellers as a result of the specific regulatory status of the
Buyer (or any of its Affiliates) or as a result of any other facts that
specifically relate to the business or activities in which the Buyer (or any
of its Affiliates) is or proposes to be engaged; (iii) result in or constitute
a default (or an event which, with notice or lapse of time, or both, would
constitute a default), or give rise to any right of termination, cancellation
or acceleration, or result in the creation of any Encumbrance upon any of the
assets of the Sellers, under any of the terms, conditions or provisions of any
note, bond, mortgage, indenture, license, agreement or other instrument or
obligation to which either of the Sellers is a party or by which either of the
Sellers, or any of the Purchased Assets may be bound, except for such defaults
(or events which, with notice or lapse of time, or both, would constitute a
default), or rights of termination, cancellation or acceleration as to which
requisite waivers or consents have been obtained or which, in the aggregate,
would not, individually or in the aggregate, create a Material Adverse Effect;
or (iv) violate any order, writ, injunction, decree, statute, rule or
regulation applicable to either of the Sellers, or any of their assets, which
violation, individually or in the aggregate, would create a Material Adverse
Effect.

approvals under the Federal Power Act, (ii) (A) notice by MPS to, and an order
by, the PUC approving the transactions contemplated by this Agreement, (B) the

with respect to the inclusion within the Purchased Assets of any rights,
franchises, privileges or similar assets of the Sellers deriving from any
private and special laws or other legislative grant or charter  (the filings
and approvals referred to in clauses (i) through (v) are collectively referred
to as the "Sellers Required Regulatory Approvals"), no declaration, filing or
registration with, or notice to, or authorization, consent or approval of any
governmental or regulatory body or authority is necessary for the consummation
by the Sellers of the transactions contemplated under this Agreement and the
other Closing Documents, other than such declarations, filings, registrations,
notices, authorizations, consents or approvals which, if not obtained or made,
will not, individually or in the aggregate, create a Material Adverse Effect.

benefit of any Employee, other than in the ordinary course of business
consistent with past practice; (f) any loan or advance (other than advances to
Employees in the ordinary course of business for travel and entertainment in
accordance with past practice) to any Person including, but not limited to,

     5.8  Title to and Condition of Properties.

     (a)  Marketable Title.  Except as set forth in Schedule 5.8(a) and except

designee will receive (i) good and marketable title to all of the Real Estate,
free and clear of all Encumbrances and (ii) good and valid title to all of the

deeds for the Real Estate and upon title insurance with respect to the U.S.
Real Property, and similar third-party assurances with respect to the Canadian

assets at each station, taken as a whole (real and personal), constituting
Purchased Assets (i) are in good operating and usable condition and repair,
free from any defects (except ordinary wear and tear, in light of their
respective ages and historical usages, and except such minor defects as do not
interfere with the use thereof in the conduct of the normal operation and
maintenance of the Purchased Assets); and (ii) have been maintained consistent
with the standards generally followed in the industry.  The Buyer acknowledges
that an item is not defective merely because it breaks or

leased, used or occupied by Sellers and included in the Purchased Assets (the
"Real Estate"), including a description of all land, exhibits indicating the
location thereof, and all Encumbrances, easements or rights of way of record
(or, if not of record, of which Sellers have notice or knowledge) granted on
or appurtenant to or otherwise affecting such Real Estate, the zoning
classification thereof, and all plants, buildings or other structures located
thereon.  Except with respect to the Millinocket Facility, which has no deeded
access rights but depends upon custom and usage as described in Schedule
5.8(c), no fact or condition exists which would prohibit or adversely affect
the ordinary rights of access to and from the Real Estate from and to the
existing highways and roads and there is no pending or threatened restriction
or denial, governmental or otherwise, upon such ingress or egress.  Except as
set forth on Schedule 5.8(c), Sellers' occupation and use of the Real Estate

or prescriptive rights involving any of the Real Estate, (ii) any structure
located on any Real Estate which encroaches on or over the boundaries of
neighboring or adjacent properties or (iii) any structure of any other party
which encroaches on or over the boundaries of any of such Real Estate.  Except
as indicated in Schedule 5.8(c), none of the Real Estate is located in a flood
plain, flood hazard area, wetland or lakeshore erosion area within the meaning
of any applicable order, decree, statute, rule, or regulation.  No public
improvements have been commenced and to the knowledge of the Sellers none are
planned which in either case may result in special assessments against any of
the Real Estate or otherwise create a Material Adverse Effect.  No portion of
any of the Real Estate has been used as a landfill or for storage or landfill
of hazardous or toxic materials.  Except as set forth on Schedule 5.8(c), the
Sellers have no knowledge of any (i) planned or proposed increase in assessed
valuations of any Real Estate, (ii) order, writ, injunction, or decree
requiring repair, alteration, or correction of any existing condition
affecting any Real Estate or the systems or improvements thereat, (iii)
condition or defect which could give rise to an order of the sort referred to
in "(ii)" above, or (iv) underground storage tanks, or any structural,
mechanical, or other defects of material significance affecting any Real
Estate or the systems or improvements thereat (including, but not limited to,
inadequacy for normal use of mechanical systems or disposal or water systems
at or serving the Real Estate). 

     (d)  No Certified Survey Map Required.  No certified survey map or other
state, municipal, or other governmental approval regarding the division,
platting, or mapping of real estate is required as a prerequisite to the
conveyance by the Sellers to Buyer (or as a prerequisite to the recording of
any conveyance document) of any Real Estate pursuant to the terms hereof.

     5.9  Leases.  Schedule 5.9 lists, as of the date of this Agreement, all
real property leases under which the Sellers are a lessee or lessor and which

no existing material defaults by the Sellers or, to the Sellers' knowledge,
any other party thereunder; and no event has occurred which (whether with or
without notice, lapse of time or both) would constitute a material default by
the Sellers or, to the Sellers' knowledge, any other party thereunder, or
would cause the acceleration of any of the Sellers' obligations thereunder or
result in the creation of any Encumbrance on any of the Purchased Assets, or
would give rise to an automatic termination, or the right of discretionary
termination, thereof. 

     5.10 Insurance.  Except as set forth in Schedule 5.10, all material
policies of fire, liability, worker's compensation and other forms of
insurance owned or held by the Sellers (including self insurance) with respect

or the business of the Sellers in connection therewith, are in full force and
effect, all premiums with respect thereto covering all periods up to and

increase in a deductible (or an increase in premiums in order to maintain an
existing deductible) or nonrenewal of any such policy.  Except as described in
Schedule 5.10, the Sellers have not been refused any insurance with respect to
the Purchased Assets, the operation or maintenance of the Purchased Assets, or

employees employed at the Purchased Assets, for the operation or maintenance
of the Purchased Assets, or in connection with the business of Sellers
relating to the Purchased Assets, without regard to the coverage of any such
plan, program or arrangement by ERISA or any provision of the Code.  The
plans, programs and arrangements listed on Schedule 5.13(a) are collectively
referred to herein as the "Benefit Plans".  Accurate and complete copies of
all Benefit Plans and all material employee communications of general
application related to such Benefit Plans have been made available to the
Buyer.

     (b)  Except as set forth in Schedule 5.13(b):

               (1)  No Pension Plan and no ERISA Affiliate Plan has ever

     Regulation - Pension Benefits Act, NB Reg. 91-195, as amended;

               (2)  None of the Sellers nor any ERISA Affiliate has incurred
     any liability to the Pension Benefit Guaranty Corporation under 
     Sections 4062, 4063, 4064 or 4069 of ERISA in connection with any 
     Pension Plan that is subject to Title IV of ERISA, and none of the

     Pension Plan that is intended to be qualified determining that such plan
     is exempt from United States Federal Income Tax under Sections 401(a) and
     501(a) of the Code.  To the Sellers' knowledge, there has been no

     before the Closing Date by the Sellers to, for, or in respect of the
     Benefit Plans, the IBEW Agreements, and the Pension Benefits Act have
     been made.

     (c)  None of the Sellers nor any ERISA Affiliate has engaged in any

prohibited by Section 44 of the General Regulation - Pension Benefits Act, NB
Reg. 91-195, as amended.

     (f)  With the exception of routine claims for benefits, including
associated appeals and disputes of denied claims, arising in the ordinary
course of administration of the Benefit Plans, no material claims,
assessments, investigations, or proceedings in arbitration or litigation, or
by or before the Superintendent of Pensions of the Province of New Brunswick
or the Labour and Employment Board (New Brunswick), relating to or arising
under any Benefit Plan are pending or, to the knowledge of Sellers, threatened
against any Seller, any ERISA Affiliate, any Benefit Plan, or any trust or
other funding arrangement created under or established as part of any Benefit
Plan, or against any trustee, fiduciary, custodian, administrator, or any
other Person, and the Sellers have no basis to anticipate that any such claim
or claims exist.

provide or contribute to a post-retirement welfare benefit plan (including,
without limitation, post-retirement medical benefits for or on behalf of

     5.15 Certain Contracts and Arrangements.

     (a)  Except (i) as listed in Schedule 5.15(a) or 7.10(b), (ii) for
contracts, agreements, personal property leases, commitments, understandings
or instruments under which all rights, benefits, duties and obligations,
contingent or otherwise, of any party or beneficiary will expire on or prior
to the Closing Date, and (iii) for agreements with suppliers entered into in
the ordinary course of business that in each case (x) do not provide for
annual payments of more than $1,000 and (y) are not material to the operation
or condition (financial or otherwise) of the Purchased Assets or the business
of the Sellers in connection therewith, the Sellers are not a party to any
written contract (including, without limitation, any employment contract),
agreement, personal property lease, commitment, understanding or instrument
relating to the business or operations of the Purchased Assets.  Accurate and
complete copies of all Sellers' Agreements have been made available to Buyer. 

     (b)  Except as disclosed in Schedule 5.15(b), each Sellers' Agreement (i)
constitutes a valid and binding obligation of MPS or MNB, and to the knowledge
of the Sellers constitutes a valid and binding obligation of the other parties
thereto, (ii) is in full force and effect, and no notice of termination has
been delivered by any party thereunder, and (iii) may be transferred to the
Buyer pursuant to this Agreement and will continue in full force and effect
thereafter, in each case without breaching the terms thereof or resulting in
the forfeiture or impairment of any rights thereunder.  Without limitation of
the foregoing, (i) no consent of The Perth-Andover Electric Light Commission
is required for the valid transfer and assignment to the Buyer of the
Agreement between MNB and The Perth-Andover Electric Light Commission dated
December 7, 1993 (which became effective on January 2, 1995), and (ii) no
consent of any other Owner of the Wyman Station is required for the valid
transfer and assignment to the Buyer of MPS's right, title and interest in and
to the Wyman Agreements and such transfer and assignment will not give rise to
any right of first refusal in favor of any other such Owner under any of the
Wyman Agreements.  

     (c)  Except as set forth in Schedule 5.15(c), there is not, under any of
the Sellers' Agreements, any default or event which, with notice or lapse of
time or both, would (i) constitute a default on the part of any of the parties
thereto, except such events of default and other events as to which requisite
waivers or consents have been obtained or which would not, individually or in
the aggregate, create a Material Adverse Effect, (ii) would give rise to an
automatic termination, or the right of discretionary termination, thereof, or
(iii) would cause the acceleration of any of the Sellers' obligations or
result in the creation of any Encumbrance on any of the Purchased Assets.

     5.16 Legal Proceedings, etc.  Except as set forth in Schedule 5.16 or in
any public filing made by MPS pursuant to the Securities Act or the Exchange
Act, there are no claims, actions, proceedings or investigations pending or,
to the knowledge of Sellers, threatened against or relating to the Sellers
before any court, governmental or regulatory authority or body acting in an
adjudicative capacity, which, if adversely determined, individually or in the
aggregate, would create a Material Adverse Effect.  Except as set forth in
Schedule 5.16 or in any public filing made by MPS pursuant to the Securities
Act or the Exchange Act, the Sellers are not subject to any outstanding
judgment, rule, order, writ, injunction or decree of any court, governmental
or 


                                   -32-

regulatory authority which, individually or in the aggregate, would create a
Material Adverse Effect.

     5.17 Permits.  All permits, licenses, franchises and other governmental
authorizations, consents and approvals, other than the Environmental Permits,
necessary to own or otherwise utilize, operate or maintain, or engage in the
business of the Sellers in connection with, the Purchased Assets as presently
conducted, are identified in Schedule 5.17 (collectively, the "Required
Permits").  Except as set forth in Schedule 5.17, the Sellers have not
received any written notification that they are, or in the future may be
considered to be, in violation of any of the Required Permits, or any law,
statute, order, rule, regulation, ordinance or judgment of any governmental or
regulatory body or authority applicable to any Required Permits, except for
notifications of violations which would not, individually or in the aggregate,
create a Material Adverse Effect.  The Sellers are in compliance with all
Required Permits, laws, statutes, orders, rules, regulations, ordinances, or
judgments of any governmental or regulatory body or authority applicable to
it, except for violations which, individually or in the aggregate, do not
create a Material Adverse Effect.

     5.18 Regulation as a Utility.  MPS is an exempt public utility holding
company within the meaning of the Holding Company Act.  MPS is subject to
regulation in the United States as a public utility or public service company
(or similar designation other than as an Exempt Wholesale Generator within the
meaning of the Holding Company Act) only by FERC and the PUC; MPS is not
subject to regulation in Canada.  MNB is subject to regulation in Canada as a
public utility only by the New Brunswick Board of Commissioners of Public
Utilities, and is subject to regulation by the National Energy Board with
respect to the international export of electricity and the construction and
operation of international power transmission lines and infrastructure; MNB is
not subject to regulation in the United States. 

     5.19 Taxes.  With respect to the Purchased Assets and the business of the
Sellers associated with the Purchased Assets, (i) all Tax Returns required to
be filed other than those Tax Returns the failure of which to file would not
create a Material Adverse Effect have been filed and, in each case when filed,
were true, complete and correct in all material respects, and (ii) all
material Taxes shown to be due on such Tax Returns have been paid in full. 
Except as set forth in Schedule 5.19, no notice of deficiency or assessment
has been received from any taxing authority with respect to liabilities for
Taxes of the Sellers in respect of the Purchased Assets (nor to the knowledge
of Sellers has any such taxing authority threatened to issue such notice or
assessment), which have not been fully paid or finally settled, and any such
deficiency shown in such Schedule 5.19 is being contested in good faith
through appropriate proceedings.  Except as set forth in Schedule 5.19, there
are no outstanding agreements or waivers extending the applicable statutory
periods of limitation for Taxes associated with the Purchased Assets for any
period.  Schedule 5.19 sets forth the taxing jurisdictions in which the
Sellers own assets or conduct business that require a notification to a taxing
authority of the transactions contemplated by this Agreement, if the failure
to make such notification, or obtain Tax clearances in connection therewith,
would either require the Buyer to withhold any portion of the Purchase Price
or would subject Buyer to any liability for any Taxes of the Sellers.

the Purchased Assets do not include any material assets that are not Year 2000
compliant.

hereunder, as if they had set it forth on a schedule hereto, any facts and
circumstances known to Buyer as of the date of this Agreement, whether known

     be disclosed on Schedule 5.9 or 5.15(a), or waive any material default
     by, or release, settle or compromise any material claim against, any
     other party thereto;

               (5)  enter into, terminate, extend or otherwise amend any real

     businesses, (x) amend in a material, adverse way, or cancel any liability
     or casualty insurance policies related thereto, (y) compromise, settle,
     withdraw, release or abate any material claims made or accruing

     (b)  Notwithstanding anything in Section 7.1(a) to the contrary, the
Sellers may, in their sole discretion, make (i) Maintenance Expenditures and
Capital Expenditures (provided that the Buyer shall not be liable for any such
expenditures in excess of the Maintenance and Capital Expenditures Amount),
and (ii) at the Sellers' expense, such other maintenance and capital
expenditures as the Sellers deem necessary. 

     (c)  A committee comprised of one Person designated by the Sellers and
one Person designated by the Buyer, and such additional Persons as may be
appointed by the Persons originally appointed to such committee (the
"Transition Committee") will be established as soon after execution of this
Agreement as is practicable to examine the business issues affecting the
Purchased Assets and related businesses of the Sellers after the date hereof,
giving emphasis to cooperation between the Buyer and the Sellers after the
execution of this Agreement.  From time to time, the Transition Committee
shall report its findings to the senior management of each of MPS and the
Buyer.

     (d)  Between the date of this Agreement and the Closing Date, in the
interest of cooperation between the Sellers and the Buyer and to permit
informed action by the Buyer

regarding its rights pursuant to Section 7.1(a) to grant, consent or to waive
prohibitions or limitations under Section 7.1(a), the parties agree as
follows.  At the sole responsibility and expense of the Buyer, the Sellers
will permit designated employees ("Observers") of the Buyer to observe all
operations of the Sellers that relate to the Purchased Assets and related
businesses, and to observe discussions with third parties relating solely to
the Purchased Assets (not including discussions with legal counsel or
accountants), and such observation will be permitted on a cooperative basis in
the presence of personnel of the Sellers but not restricted to the normal
business hours of the Sellers; provided, however, that such Observers and
their actions shall not unreasonably interfere with the operation of the
Sellers' business.  The Buyer's Observers may recommend or suggest actions be
taken or not be taken by the Sellers; provided, however, that the Sellers will
be under no obligation to follow any such recommendations or suggestions and
the Sellers shall be entitled, subject to this Agreement, to conduct their
business in accordance with their own judgment and discretion.  The Buyer's
Observers shall have no authority to bind or make agreements on behalf of the
Sellers; to conduct discussions with or make representations to third parties
on behalf of the Sellers; or to issue instructions to or direct or exercise
authority over the Sellers or any of the Sellers' officers, employees,
advisors or agents.

     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 relating to the Assumed Obligations to which the Buyer is not denied
access by law; (ii) permit the Buyer 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 or the Assumed Obligations as the Buyer may from time to time
reasonably request; (iv) furnish the Buyer a copy of each material report,
schedule or other document filed or received by them with respect to the
Purchased Assets or the Assumed Obligations with the SEC, PUC, DEP, FERC, the
National Energy Board, the Board of Commissioners of Public Utilities of the
Province of New Brunswick, or the Superintendent of Pensions of the Province
of New Brunswick; 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 are under a legal obligation not to supply.  Notwithstanding anything
in this Section 7.2 to the contrary, (i) the Sellers will only furnish or
provide such access to Transferring Employee Records and personnel and medical
records as is permitted or required by law, legal process or subpoena and (ii)
the Buyer shall not have the right to perform or conduct any environmental
sampling or testing at, in, on, or underneath the Purchased Assets, except as
set forth on Schedule 7.2 hereof.

     (b)  All information furnished to or obtained by the Buyer and the
Buyer's Representatives pursuant to this Section 7.2 shall be subject to the
provisions of the Confidentiality Agreement and shall be treated as
"Proprietary Information" (as defined in the Confidentiality Agreement).

<PAGE>

     (c)  For a period of six years after the Closing Date, each party and
their representatives shall have reasonable access to all of the books and
records of the Purchased Assets, including all Transferring Employee Records
or other personnel and medical records permitted or required by law, legal
process or subpoena, in the possession of the other party or parties to the
extent that such access may reasonably be required by such party in connection
with the Assumed Obligations or the Excluded Liabilities, or other matters
relating to or affected by the operation of the Purchased Assets.  Such access
shall be afforded by the party or parties in possession of such books and
records upon receipt of reasonable advance notice and during normal business
hours.  The party or parties exercising this right of access shall be solely
responsible for any costs or expenses incurred by it or them pursuant to this
Section 7.2(c).  If the party or parties in possession of such books and
records shall desire to dispose of any such books and records upon or prior to
the expiration of such six-year period, such party or parties shall, prior to
such disposition, give the other party or parties a reasonable opportunity at
such other party's or parties' expense, to segregate and remove such books and
records as such other party or parties may select.

     (d)  Notwithstanding the terms of the Confidentiality Agreement and
Section 7.2(b) above, the parties agree that prior to the Closing the Buyer
may reveal or disclose Proprietary Information to any other Persons in
connection with financing, and risk management if reasonably necessary, of or
with respect to the Purchased Assets, and to such Persons with whom the Buyer
expects it may have business dealings regarding the Purchased Assets from and
after the Closing Date, and, to the extent that the Sellers consent (which
consent shall not be unreasonably withheld) to existing and potential
customers and suppliers, in each case only so long as such other parties enter
into confidentiality agreements in favor of MPS on terms satisfactory to MPS.

     (e)  Except as required by law, unless otherwise agreed to in writing by
the Buyer, for a period commencing on the Closing Date and terminating three
years after such date the Sellers shall keep (i) all Proprietary Information
confidential and not disclose or reveal any Proprietary Information to any
Person other than Sellers' Representatives who are actively and directly
participating in the transactions contemplated hereby or who otherwise need to
know the Proprietary Information for such purpose and to cause those Persons
to observe the terms of this Section 7.2(e) and (ii) not to use Proprietary
Information for any purpose other than consistent with the terms of this
Agreement and the other Closing Documents.  The Sellers shall continue to hold
all Proprietary Information according to the same internal security procedures
and with the same degree of care regarding its secrecy and confidentiality as
currently applicable thereto.  The Sellers shall notify the Buyer of any
unauthorized disclosure to third parties that it discovers, and shall endeavor
to prevent any further such disclosures. The Sellers shall be responsible for
any breach of the terms of this Section 7.2(e) by the Sellers or the Sellers'
Representatives.  

     After the Closing Date, in the event that the Sellers are requested
pursuant to, or required by, applicable law or regulation or by legal process
to disclose any Proprietary Information, or any other information concerning
the Purchased Assets, or the transactions contemplated hereby, the Sellers
shall provide the Buyer with prompt notice of such request or requirement in
order to enable the Buyer to seek an appropriate protective order or other
remedy, to consult with the Sellers with respect to taking steps to resist or
narrow the scope of such request or legal process, or to waive compliance, in
whole or in  

                                   -39-

                                       -179-

<PAGE>

part, with the terms of this Section 7.2(e).  The Sellers agree not to oppose
any action by the Buyer to obtain a protective order or other appropriate
remedy after the Closing Date.  In the event that no such protective order or
other remedy is obtained, or that the Buyer waives compliance with the terms
of this Section 7.2(e), the Sellers shall furnish only that portion of the
Proprietary Information which the Sellers are advised by counsel is legally
required.  In any such event the Sellers shall use their reasonable best
efforts to ensure that all Proprietary Information and other information that
is so disclosed will be accorded confidential treatment. 

     (f)  The parties agree that the Confidentiality Agreement will terminate,
without further act or evidence by the parties, upon consummation of the
Closing. 

     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.

     7.4  Further Assurances.

     (a)  Subject to the terms and conditions of this Agreement, each of the
parties hereto will use its best efforts to take, or cause to be taken, all
action, 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,
including without limitation using its best efforts to ensure satisfaction of
the conditions precedent to each party's obligations hereunder. 
Notwithstanding anything in the previous sentence to the contrary, the Sellers
and the Buyer shall use their commercially reasonable efforts to obtain all
Permits and Environmental Permits necessary for the Buyer to own, operate and
maintain the Purchased Assets and to deliver the output thereof to MPS's
transmission system at the respective interconnection points specified in the
Interconnection Agreements.  Neither of the parties hereto will, without prior
written consent of the other party, take or fail to take any action, which
would reasonably be expected to prevent or materially impede, interfere with
or delay the transactions contemplated by this Agreement.  From time to time
after the date hereof, without further consideration, the Sellers will, at
their own expense, execute and deliver such documents to the Buyer or its
designee as the Buyer may reasonably request in order to more effectively vest
in the Buyer the Sellers' title to the Purchased Assets subject only to
Permitted Encumbrances.  Without limiting the foregoing, the Sellers shall
cooperate with the Buyer in the Buyer's efforts to cure or remove any defects
or Encumbrances existing with respect to the Real Estate that the Buyer
reasonably deems objectionable; provided, however, that in connection
therewith the Sellers shall not be under any obligation to initiate legal
action or to incur expense other than reasonable administrative and
out-of-pocket expenses.  From time to time after the date hereof, the Buyer
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)  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 

                                   -40-

                                       -180-

<PAGE>

constitute a breach thereof or be unlawful, and the Sellers, at their expense,
shall use their commercially reasonable efforts to obtain any such required
consents 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 or
its designee's rights and obligations under the Sellers' Agreement in question
so that the Buyer or its designee 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 after the Closing (assuming that the
Buyer, in its sole and absolute discretion, waives in writing the condition
precedent to Closing set forth in Section 8.2(k)), appoint the Buyer or its
designee to be the Sellers' representative and agent with respect to such
Sellers' Agreement, and the Sellers shall, to the maximum extent permitted by
law and such Sellers' Agreement, enter into such reasonable arrangements with
the Buyer or its designee as are necessary to provide the Buyer or its
designee with the benefits and obligations of such Sellers' Agreement.  The
Sellers and the Buyer shall cooperate and shall each use their commercially
reasonable efforts after the Closing to obtain an assignment of such Sellers'
Agreement to the Buyer or its designee.

     7.5  Public Statements.  The parties shall consult with each other prior
to issuing any public announcement, statement or other disclosure with respect
to this Agreement or the transactions contemplated hereby and shall not issue
any such public announcement, statement or other disclosure prior to such
consultation, except as may be required by law and except that the parties may
make public announcements, statements or other disclosures with respect to
this Agreement and the transactions contemplated hereby to the extent and
under the circumstances in which the parties are expressly permitted by the
Confidentiality Agreement to make disclosures of "Proprietary Information" (as
defined in the Confidentiality Agreement).

     7.6  Consents and Approvals; Financing.

     (a)  The Sellers and the Buyer agree that there is no need to file with
the Federal Trade Commission or the United States Department of Justice any
notifications under the HSR Act and the rules and regulations promulgated
thereunder with respect to the transactions contemplated hereby.

     (b)  The Sellers and the Buyer shall cooperate with each other and (i)
promptly prepare and file all necessary documentation, (ii) effect all
necessary applications, notices, petitions and filings and execute all
agreements and documents, (iii) use all commercially reasonable efforts to
obtain the transfer or reissuance to the Buyer of all necessary Transferable
Permits, consents, approvals and authorizations of all governmental bodies and
(iv) use all commercially reasonable 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 Sellers Required Regulatory Approvals and the Buyer Required
Regulatory Approvals) 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 the Sellers or the Buyer is a party or by
which any 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 

                                   -41-

                                       -181-

<PAGE>

Agreement which appear in any filing made in connection with the transactions
contemplated hereby. 

     (c)  The Sellers and the Buyer shall cooperate with each other and
promptly prepare and file notifications with, and request Tax clearances from,
state, provincial and local taxing authorities in jurisdictions in which a
portion of the Purchase Price may be required to be withheld or in which the
Buyer would otherwise be liable for any Tax liabilities of the Sellers
pursuant to such state and local Tax law. 

     (d)  Notwithstanding anything herein to the contrary, the Sellers shall
use all commercially reasonable efforts to assist Buyer in obtaining all third
party consents (including, without limitation, consents to the collateral
assignment in favor of the Buyer's lenders of contracts or agreements included
in the Purchased Assets), agreements, certificates, opinions, and other
documents or instruments reasonably requested by the Buyer's lenders in
connection with the financing, on a non- or limited recourse basis or
otherwise, of Buyer's acquisition of the Purchased Assets hereunder, all of
which shall be at Buyer's sole cost and expense to the extent that any such
items are not otherwise required of Sellers hereunder or under any of the
Closing Documents.  From time to time after the date hereof, without further
consideration, the Sellers will, at their own expense, execute and/or deliver
such consents (including, without limitation, consents to the collateral
assignment in favor of the Buyer's lenders of the Closing Documents),
agreements, certificates, opinions, and other documents or instruments to the
Buyer's lenders as the Buyer's lenders may reasonably request in connection
with the financing, on a non- or limited recourse basis or otherwise, of
Buyer's acquisition of the Purchased Assets hereunder.  Sellers acknowledge
that Buyer intends to obtain financing, on a non- or limited recourse basis or
otherwise and on terms and conditions acceptable to Buyer, of Buyer's
acquisition of the Purchased Assets hereunder and Buyer confirms that
obtaining such financing is not a condition precedent to its obligations
hereunder.

     7.7  Fees and Commissions.  The Sellers and the Buyer each represent and
warrant to the other that no broker, finder or other Person is entitled to any
brokerage fees, commissions or finder's fees in connection with the
transaction contemplated hereby by reason of any action taken by the party
making such representation.  The Sellers and the 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 finder's fees incurred by reason of any action taken by such
party. 

     7.8  Tax Matters.

     (a)  All transfer and sales taxes incurred in connection with this
Agreement and the transactions contemplated hereby shall be borne by the
Sellers, other than Maine real estate transfer taxes which shall be paid
equally by Buyer and MPS, and MPS, 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 Buyer will join in the execution of any such
Tax Returns or other documentation.  Prior to the Closing Date, MPS will
provide to the Buyer, to the extent possible, an appropriate certificate of no
Tax 

                                   -42-

                                       -182-

<PAGE>

incurred in connection with this Agreement and the transactions contemplated
hereby, from each applicable taxing authority.

     (b)  With respect to Taxes to be prorated in accordance with Section 3.5
of this Agreement only, the Buyer shall prepare and timely file all Tax
Returns required to be filed after the Closing with respect to the Purchased
Assets, if any, for the period in which such Taxes must be reported, and shall
duly and timely pay all such Taxes 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 filing such Tax
Return.  Within ten (10) Business Days after receipt of such Tax Return, the
Sellers shall pay to the Buyer their proportionate share of the amount shown
as due on such Tax Return determined in accordance with Section 3.5 of this
Agreement.

     (c)  Each of the Buyer and the Sellers shall provide the other with such
assistance as may reasonably be requested by the other party in connection
with the preparation of any Tax Return, any audit or other examination by any
taxing authority, or any judicial or administrative proceedings relating to
liability for Taxes, and each will retain and provide the requesting party
with any records or information which may be relevant to such return, audit or
examination, proceedings or determination.  Any information obtained pursuant
to this Section 7.8(c) or pursuant to any other Section hereof providing for
the sharing of information or review of any Tax Return or other schedule
relating to Taxes shall be kept confidential by the parties hereto.

     7.9  Supplements to Schedules.  Prior to the Closing Date, the Sellers
and the Buyer shall supplement or amend the Schedules referenced in this
Agreement with respect to any matter relating to the subject matter thereof
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, or expand or limit the scope
of, or otherwise modify or affect any representation or warranty made in this
Agreement unless the parties agree thereto in writing.

     7.10 Employees.

     (a)  During the period beginning on the date of this Agreement and ending
on the Closing Date (the "Buyer's Window"), the Buyer or its designee may
offer employment, effective as of the Closing Date, to employees of the
Sellers who are presently employed principally in connection with the
ownership, operation, or maintenance of the Purchased Assets, and who are
assigned to the departments listed in Schedule 7.10(a) and listed individually
in such Schedule 7.10(a) (all such employees hereinafter referred to
individually as an "Employee" and collectively as "Employees"); provided,
however, that if any such individual ceases to be employed by either of the
Sellers after the date hereof, Buyer or its designee may offer employment
during the Buyer's Window, effective as of the Closing Date, to any individual
or individuals who, in general, performs the functions and duties of such
departed individual (and any such replacement individual or individuals, as
the case may be, shall be deemed an "Employee" for the purposes of this
Section 7.10). 

                                   -43-

                                       -183-

<PAGE>

     All such offers of employment shall be made (i) in accordance with all
applicable laws and regulations, and (ii) for Employees represented by the
International Brotherhood of Electrical Workers ("IBEW"), in accordance with
the applicable IBEW Agreements (or any replacement or extension thereof as in
effect at such time).  (Each person who becomes employed by the Buyer or its
designee as of the Closing Date pursuant to this Section 7.10 shall be
referred to herein as a "Transferred Employee.")

     During the Buyer's Window, the Sellers will refrain from offering
post-Closing employment to any of the Employees without the prior consent of
the Buyer, other than those Employees who the Buyer indicates in writing it
does not intend to hire.  Buyer shall in good faith notify Seller as soon as
possible regarding those employees who the Buyer does not intend to offer
employment.  The Buyer shall not solicit, directly or indirectly, for
employment any employees of the Sellers 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 the provisions set forth below, the Sellers shall not, at any
time beginning at the end of the Buyer's Window and ending on the second
anniversary of the Closing Date, solicit, directly or indirectly, for
employment any Employee who accepted a position with the Buyer or its designee
within the Buyer's Window.  In the event the Buyer or its designee decides to
terminate the employment of one or more of the Transferred Employees on or
before 12 months following the Closing Date, Buyer or its designee shall
provide Sellers with at least seventy-five (75) days advance written notice,
following which Sellers shall have the right to offer employment to any such
affected Transferred Employee, such employment to commence no sooner than the
effective date of the Transferred Employee's employment termination with Buyer
or its designee, as the case may be.  

     With respect to any Employee who does not receive an offer of employment
from the Buyer or its designee, the Sellers shall be responsible for providing
such Employees with any benefits under the Sellers' Employee Transition Plan,
which such Employees may be entitled to receive under the terms of said Plan. 
If, for any reason, any Employee has received severance benefits under the
Sellers' Employee Transition Plan and is subsequently employed by Buyer at any
time on or before the one (1) year anniversary of the Closing Date, Buyer
shall reimburse the Sellers for the cost of any such severance benefits,
whether such severance benefits are provided in cash or in kind. 

     (b)  Schedule 7.10(b) sets forth all of the collective bargaining
agreements, and amendments thereto, to which the Sellers are a party with the
IBEW in connection with the Purchased Assets (the "IBEW Agreements").  With
respect to Transferred Employees who are included in the collective bargaining
units covered by the IBEW Agreements (the "Transferred IBEW Employees"), as of
the Closing Date the Buyer or its designee will assume the IBEW Agreements as
they relate to Transferred IBEW Employees. The Buyer or its designee shall
comply with all applicable obligations under the IBEW Agreements and will
accept and fulfill all obligations under the IBEW Agreements, together with
any revisions and/or extensions thereto, including, but not limited to, the
obligation of Buyer or its designee to recognize the IBEW as the collective
bargaining agent for the Transferred IBEW Employees.  Transferred IBEW
Employees

                                       -184-

<PAGE>

shall be given credit for prior service with the Sellers for all purposes
under the IBEW Agreements.

     (c)  For the period commencing on the Closing Date and ending 
December 31, 2001, the Buyer or its designee shall provide all Transferred
Employees who remain in its employ and who are not IBEW Employees
("Transferred Non-Union Employees") with total salary, benefits and
opportunities for bonuses which is, in the aggregate, comparable to the total
salary, benefits and opportunities for bonuses provided to such Employees by
the Sellers immediately prior to the Closing Date.  Nothing herein shall be
deemed to guarantee a Transferred Employee continued employment with the Buyer
or its designee for any definite period of time.

     (d)  As of the Closing Date, all Transferred Employees shall, except as
otherwise provided in this Section 7.10 or required by applicable law, cease
to participate in the Welfare Plans and shall commence to participate in the
employee welfare benefit plans, programs, and arrangements of the Buyer and
its Affiliates, without regard to the coverage of any such plan, program, or
arrangement by ERISA or any provision of the Code (the "Replacement Welfare
Plans") on at least the same terms and conditions as similarly situated
employees of the Buyer.  The Buyer shall (i) waive or cause to be waived,
except to the extent that such waiver is precluded by applicable law, any
waiting period, probationary period, pre-existing condition exclusion,
evidence of insurability requirement, or similar condition with respect to
Transferred Employees under the Replacement Welfare Plans, other than, but
only to the extent of, any waiting period, probationary period, pre-existing
condition exclusion, evidence of insurability requirement, or similar
condition that was in effect with respect to any such Transferred Employee
under a Welfare Plan of the Seller and that had not been satisfied by such
individual as of the Closing Date, and (ii) provide each such Transferred
Employee with credit for satisfaction of any deductible, co-payment, or
similar out-of-pocket payment requirement under the Replacement Welfare Plans
to the extent of the deductible, co-payments, and similar out-of- pocket
payments paid prior to the Closing Date under the Sellers' Welfare Plans (on a
pro-rata basis in the event of a difference in plan years).

     (e)  The Buyer shall credit the service of each Transferred Non-Union
Employee with the Sellers and their Affiliates, including, without limitation,
accrued vacation and sick time, for purposes of eligibility, participation,
vesting, and accrual of or entitlement to benefits under all employee benefit
plans, programs, and arrangements of the Buyer and its Affiliates, without
regard to the coverage of any such plan, program, or arrangement by ERISA or
any provision of the Code ("Buyer Benefit Plans") in which they become
participants to the same extent as if such service had been performed for the
Buyer or its designee; provided that the benefits provided under the Buyer
Benefit Plans may be offset by the nonforfeitable benefits previously provided
by the Sellers or the Sellers' Benefit Plans with respect to the same period
of service.

     (f)  Each Transferred Non-Union Employee who is eligible to participate
in the Maine Public Service Company Non-Union Retirement Savings Plan
("Sellers' Non-Union 401(k) Plan") immediately before the Closing Date shall
be eligible to participate in Wisconsin Public Service Corporation
Administrative Employees' Savings Plan, a tax-qualified defined contribution
plan including a cash-or-deferred arrangement of the Buyer or one of its
Affiliates ("Buyer's 401(k) Plan") as of the Closing Date. The Buyer shall
take any and all necessary action to cause the

                                       -185-

<PAGE>

trustee of a tax-qualified defined contribution plan of the Buyer or one of
its Affiliates, if requested to do so by a Transferred Non-Union Employee, to
accept a direct "rollover" of all or a portion of said employee's distribution
from the Sellers' Non-Union 401(k) Plan.

     (g)  The Buyer shall make (or cause to be made) any and all amendments to
its employee benefit plans, programs, and arrangements necessary to give
effect to its obligations under this Agreement, which amendments shall be
effective as of the Closing Date and delivered to the Sellers within a
reasonable time after the Closing Date.

     (h)  Provided Buyer has given Sellers at least seventy-five (75) days
advance written notice and Sellers have not extended an offer of comparable
employment, the Buyer shall pay to each Transferred Employee whose employment
is involuntarily terminated by the Buyer or its designee within 12 months
after the Closing Date, (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 severance benefits that would have
been provided to such individual upon such termination by the Sellers under
the Sellers' Employee Transition Plan to the extent identified as to nature
and amount in the Sellers' Employee Transition Plan, had such individual
remained continuously employed by the Sellers and had been eligible under, and
covered by, such plan on the date of such termination; the Seller will
reimburse Buyer for the cost of such severance benefits.  With respect to each
Transferred Employee whose employment is involuntarily terminated by the Buyer
or its designee on or after 12 months following the Closing Date but on or
before 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), Buyer or its designees shall pay
the severance benefits that would have been provided to such individual upon
such termination by the Sellers under the Sellers' Employee Transition Plan to
the extent identified as to nature and amount in the Sellers' Employee
Transition Plan, had such individual remained continuously employed by the
Sellers and had been eligible under, and covered by, such plan on the date of
such termination.

     (i)  Subject to the other provisions of this Section 7.10, and except as
specifically provided to the contrary in this Agreement:

          (1)  The Sellers, and not the Buyer or its designee, shall be
responsible and shall assume any and all liability for (A) 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 COBRA and compliance with HIPAA; and (B) all
notices, payments, fines, taxes or assessments due to any governmental
authority pursuant to any applicable foreign, federal, state, provincial or
local law, common law, statute, rule or regulation with respect to the
employment, discharge or layoff of employees employed at the Purchased Assets,
including, but not limited to, the WARN Act, the Employment Standards Act (New
Brunswick), and any rules or regulations that have been issued in connection
with any of the foregoing. 

          (2)  The Buyer, and not the Sellers, shall be responsible and shall
assume any and all liability for (A) all compensation, benefits, and
perquisites of any kind due any Transferred Employee on account of employment
by the Buyer or its designee on and after the Closing Date, 

                                   -46-

                                       -186-

<PAGE>

or the termination of employment by the Buyer or its designee, including, but
not limited to, continuation of health care coverage pursuant to COBRA and
compliance with HIPAA; and (B)  all notices, payments, fines, taxes or
assessments due to any governmental authority pursuant to any applicable
foreign, federal, state, provincial or local law, common law, statute, rule or
regulation with respect to the employment, discharge or layoff of Transferred
Employees by the Buyer or its designee, including, but not limited to, the
WARN Act, the Employment Standards Act (New Brunswick), and any rules or
regulations that have been issued in connection with any of the foregoing.
 
     (j)  The Sellers acknowledge that the benefits identified in the Sellers'
Employee Transition Plan are intended to cover all benefits that the
Transferred Employees are entitled to by law and the IBEW Agreements.  In the
event that any Transferred Employee successfully claims in a court of
competent jurisdiction that, under applicable law or the IBEW Agreements,
severance benefits are due to such Transferred Employee in addition to those
benefits identified as to nature and amount in the Sellers' Employee
Transition Plan, then the Sellers shall pay directly or reimburse the Buyer
for costs and expenses related to any additional benefits actually paid to
such Transferred Employee (as well as costs and expenses associated with
defending such action brought by such Transferred Employee) by the Buyer or
its Affiliates; provided however, that the Sellers shall only be required to
make any such payment or reimbursement if such benefits (A) arise out of such
Transferred Employee's employment with the Sellers, and (B) are not due to
some act or omission by the Buyer or any of its Affiliates.  The Buyer and the
Sellers agree that the terms of Section 9.2 hereof shall apply to this Section
7.10(j) as if set forth herein.

     7.11 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 are taken by eminent domain or expropriation or become 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.  If such taking would create a Material Adverse Effect, 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,
consummate the transaction contemplated by this Agreement pursuant to the
terms of this Agreement.  If no such settlement is reached within sixty (60)
days after the Sellers have notified the Buyer of such taking, then the Buyer
or the Sellers may terminate this Agreement pursuant to Section 10.1(f).

     (c)  If, before the Closing Date all or any material portion of the
Purchased Assets are damaged or destroyed by fire or other casualty, the
Sellers shall notify the Buyer promptly in writing of such fact.  If such
damage or destruction would create a Material Adverse Effect and the Sellers
have not notified Buyer of their intention to cure such damage or destruction
within fifteen (15) days after its occurrence, the Buyer and the Sellers shall
negotiate in good faith to settle the loss resulting from such casualty
(including, without limitation, by making a fair and equitable adjustment to
the Purchase Price) and, upon such settlement, consummate the 

                                   -47-

                                       -187-

<PAGE>

transactions contemplated by this Agreement pursuant to the terms of this
Agreement.  If (i) no such settlement is reached within sixty (60) days after
the Sellers have notified the Buyer of such casualty, or (ii) Sellers have
notified Buyer of their intention to cure in accordance with the preceding
sentence, but (x) Sellers have not proceeded diligently and in good faith to
promptly cure such damage or destruction, or (y) such cure is not completed to
Buyer's reasonable satisfaction not less than 60 days prior to the Termination
Date, then the Buyer or the Sellers may terminate this Agreement pursuant to
Section 10.1(f).

     7.12 Real Estate Title; Title Insurance; Surveys.

     (a)  Buyer is currently in the process of obtaining title insurance
commitments, and Sellers are currently in the process of obtaining surveys,
for the Real Estate.  Both parties shall diligently pursue the completion of
such matters and each agrees to cooperate with the other toward the goal of
providing a complete set of surveys and title insurance commitments for the
Real Estate meeting the requirements of this Section 7.12 as soon as is
practicable but in any event within sixty (60) days after the date hereof. 
The date on which such materials are completed shall be referred to as the
"Initial Title Review Date".

     (b)  Within sixty (60) days after the Initial Title Review Date, the
Buyer shall notify the Sellers in writing of any defects in title that would
make the Sellers unable to convey good and marketable title to the Real Estate
free of Encumbrances other than Permitted Encumbrances, whether such defects
are disclosed herein or in the surveys and title commitments referred to above
(any of which is called herein a "Defect of Title").  The Buyer shall be
deemed to have waived any objection to any Defect of Title that existed as of
the effective date of the title insurance commitments that are provided on the
Initial Title Review Date if the Buyer fails to notify the Sellers of such
Defect of Title within such sixty-day period.  If Sellers notify Buyer that
they are, despite reasonable efforts, unable to cure a Defect of Title
(including obtaining affirmative coverage through Buyer's title insurance
company) then Buyer shall elect, within thirty (30) days after receipt of
Seller's notice, either (i) to accept title to the Real Estate subject to the
uncured Defects of Title, or (ii) if such uncured Defect of Title constitutes
a Material Adverse Effect, to terminate this Agreement in accordance with
Section 10.1(e); Buyer's failure to so elect within such time period shall
constitute an election to accept title subject to such uncured Defect of
Title.  With respect to any Defect of Title that does not exist on the
effective date of the title insurance commitments that are provided on the
Initial Title Review Date, but which arises prior to Closing, the Buyer shall
notify the Sellers in writing of any such Defect of Title on or prior to the
Closing.  The Sellers shall have, at their option, a period of not more than
90 days after receipt of any such notice within which to remedy or cure any
such Defect of Title to the reasonable satisfaction of the Buyer.  If the
Sellers elect to remedy or cure such Defect of Title, then the Closing shall
be extended, if necessary, to a date that is not more than five (5) business
days after the expiration of such 90-day period.  If such Defect of Title is
not corrected or remedied to the reasonable satisfaction of the Buyer within
such 90-day period, the Buyer shall elect, by written notice to the Sellers
within ten (10) days after the expiration of such 90-day period, either (i) to
accept title to the Real Estate subject to the uncured Defects of Title, or
(ii) if such uncured Defect of Title constitutes a Material Adverse Effect, to
terminate this Agreement in accordance with Section 10.1(e); Buyer's failure
to so elect within such time period shall constitute an election to accept
title subject to such uncured Defect of Title.  Sellers shall have the option
to 

                                   -48-

                                       -188-

provide affirmative title insurance coverage over (which Buyer, at Sellers'
expense, shall assist in attempting to obtain and provided that Sellers are
responsible for any increase in cost attributable to such coverage), or to
indemnify Buyer pursuant to Section 9.1 against, one or more uncured Defects
of Title.  Any such  indemnification shall be subject to the limitations of
Section 9.1(g)(2) and (3), but shall not be subject to the time limitations of
Section 9.1 (g)(1).  Notwithstanding the prior two sentences, Buyer shall not
be required to accept an indemnity from Sellers with respect to any Defects of
Title. 

     (c)  The title insurance commitments referred to herein shall be issued
by a title insurance company or companies reasonably satisfactory to Buyer,
agreeing to issue to Buyer or its designee standard form owner's policies of
title insurance with respect to all Real Estate, together with a copy of each
document to which reference is made in such commitments.  To the extent that
title insurance is not available for the Canadian Real Estate, then Buyer
shall obtain the equivalent thereof commonly used for commercial transactions
in New Brunswick, Canada.  Such policies shall be standard ALTA form 1992
owner's policies (or the Canadian equivalent in respect of the Canadian Real
Estate) in the full amount of the fair value of the Real Estate allocated
respectively to each subject parcel of Real Estate under Section 3.3 hereof,
insuring good and marketable title thereto (expressly including all easements
and other appurtenances).  All policies shall insure title in full accordance
with the representations and warranties set forth herein and shall be subject
only to such conditions and exceptions as shall be reasonably acceptable to
Buyer and shall contain such endorsements as Buyer shall reasonably request.

     (d)  The surveys of the Real Estate shall be prepared in accordance with
ALTA/ACSM 1997 standards, or the Canadian equivalent in respect of the
Canadian Real Estate, each detailing the legal description, the perimeter
boundaries, all improvements located thereon, all easements and encroachments
affecting each such parcel of Real Estate and such other matters as may be
reasonably requested by Buyer or the title insurance companies, each
containing a surveyor certificate reasonably acceptable to Buyer and the title
insurance companies, and each prepared by a registered land surveyor in the
jurisdiction where the Real Estate is located reasonably satisfactory to
Buyer. 

     (e)  Sellers and Buyer agree to use the descriptions set forth in the
surveys referred to above, once they have been accepted by Buyer, as the deed
descriptions for the Real Estate. 

     (f)  Sellers and Buyer agree that the aggregate out-of-pocket cost of
obtaining the title insurance commitments and final policy coverage (and the
Canadian equivalent), and the surveys referred to in this Section 7.12 shall
be paid half by the Sellers and half by the Buyer and that Sellers and Buyer
intend to rely upon such surveys for all matters relating to real property
descriptions and the status of title, except as otherwise provided in Section
7.12(b), and that such surveys shall run to the benefit of Sellers and Buyer. 
Furthermore, Buyer agrees that it shall not pursue the Sellers under their
deeds to the Real Estate until it has first obtained whatever it may be owed
under its owner's title insurance policies with respect to such claims.

     7.13 Wyman Agreements.  MPS agrees that it shall deliver any notices to
the Owners (as defined in the Wyman Agreements) required under the Wyman
Agreements as a result of the proposed transfer to Buyer or its designee of
MPS's interest thereunder.

                              INDEMNIFICATION

     9.1  Indemnification.

     (a)  The Sellers will jointly and severally indemnify, defend and hold
harmless the Buyer from and against any and all claims, demands or suits (by
any Person), losses, liabilities, damages (including consequential or special
damages), obligations, payments, costs and expenses (including, without
limitation, the costs and expenses of any and all actions, suits, proceedings,
assessments, judgments, settlements and compromises relating thereto and
reasonable attorneys' fees and reasonable disbursements in connection
therewith) (each, an "Indemnifiable Loss"), asserted against or suffered by
the Buyer relating to, resulting from or arising out of (i) any breach by the
Sellers of any covenant or agreement of the Sellers contained in this
Agreement or in any of the Closing Documents or the inaccuracy or breach as of
the date hereof or thereof, as the case may be, or on the Closing Date of any
representation or warranty of the Sellers in this Agreement or in any of the
Closing Documents, or (ii) the Excluded Liabilities.  Notwithstanding the
foregoing, the Sellers shall have no liability hereunder after the Closing
Date with respect to the condition of title of the Real Estate, except as set
forth in the deeds to the Real Estate delivered to the Buyer at the Closing. 
Furthermore, Buyer agrees that it shall pursue Sellers under their deeds for
the Real Estate only after it has obtained whatever it may be owed under its
owner's title insurance policies with respect to such claims. 

     (b)  The Buyer will indemnify, defend and hold harmless the Sellers from
and against any and all Indemnifiable Losses asserted against or suffered by
the Sellers relating to, resulting from or arising out of (i) any breach by
the Buyer or its designee of any covenant or agreement of the Buyer or its
designee contained in this Agreement or in any of the Closing Documents or the
inaccuracy or breach as of the date hereof or thereof, as the case may be, or
on the Closing Date of any representation or warranty of the Buyer in this
Agreement or in any of the Closing Documents, (ii) the Assumed Obligations
(including those that are assumed by Buyer's designee), or (iii) any actions
of the Observers.

     (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 by any amounts actually and irrevocably
recovered by the Indemnitee with respect to such claim or the underlying facts
under insurance policies, (i) net of any increase that will occur, or is
reasonably likely to occur, in insurance premiums payable by the Indemnitee,
whether by retrospective premium adjustments or any other premium increase
under the policy or policies under which the claim is made or any other
policy,

where the increase results directly from filing the insurance claim and (ii)
less, dollar for dollar, the amount by which the insurance claim when filed or
at any time during the applicable policy period, either singly or in the
aggregate with all other claims made under the applicable policy or policies,
exceeds the policy coverage limit; provided, however, that this subsection
shall apply only if this provision does not constitute an improper waiver of
the insurer's rights of subrogation against the Indemnifying Party.  Nothing
contained in this Section 9.1(c) shall be deemed to create an obligation of
any party hereto to maintain any form or level of insurance after the Closing,
to name any other party as an additional insured or to obtain approval for any
waiver of rights of subrogation. 

     (d)  The expiration, termination or extinguishment of any representation,
warranty, covenant or agreement, or the time within which to make a claim
hereunder with respect thereto, 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)  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
covenant or agreement or representation or warranty set forth in this
Agreement or (ii) the Assumed Obligations or the Excluded Liabilities, as the
case may be, provided, however, that the foregoing limitation shall not apply
to the parties' respective obligations after the Closing Date under the
Buy-Back Agreement, the Continuing Site Agreement, the Interconnection
Agreements or the Instruments of Assumption.

     (f)  Buyer and Sellers each agree that notwithstanding any provisions in
this Agreement to the contrary, all parties to this Agreement retain their
remedies at law or in equity with respect to willful, knowing or intentional
breaches of this Agreement, including a failure to consummate the Closing
hereunder when and if required to do so.

     (g)  Except for any willful, knowing or intentional breach or 
misrepresentation, as to which claims may be brought without limitation as to
time or amount: 

          (1)  Any claim or action shall be brought under this Article IX for
     breach of a representation or warranty within two (2) years after the
     Closing Date.  Regardless of the foregoing, however, or any other
     provision of this Agreement:  (A) there shall be no time limitation
     hereunder on claims or actions brought for breach of any representation
     or warranty made in or pursuant to Sections 5.1, 5.2, 5.3, 6.1, 6.2 or
     6.3; (B) a claim or action brought for breach of any representation or
     warranty made in or pursuant to Section 5.11 hereof must be brought
     within five (5) years after the Closing Date; (C) any claim or action
     brought for breach of any representation or warranty made in or pursuant
     to Section 5.19 may be brought at any time until the underlying tax
     obligation is barred by the applicable period of limitation under
     federal, state and foreign laws relating thereto (as such period may be
     extended by waiver) and (D) there shall be no time limitation

     hereunder for claims against Sellers under the deeds to the Real Estate
     or with respect to any indemnity given by the Sellers to cure a Title
     Defect pursuant to Section 7.12; 

          (2)  An Indemnitee shall not be entitled to indemnification under
     this Article IX for breach of a representation or warranty unless the
     aggregate of the Indemnifying Party's indemnification obligations to the
     Indemnitee pursuant to this Article IX (but for this Section 9.1(g)(2))
     exceeds $100,000; but in such event, the Indemnified Party shall be
     entitled to indemnification for amounts in excess thereof; and 

          (3)  An Indemnifying Party's aggregate indemnification
     obligations under this Article IX for breach of a representation or
     warranty shall not exceed $3,000,000.

     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 reasonably prompt written notice thereof, but in any event
not later than sixty (60) days after receipt of notice thereof.  Such notice
shall specify this Section of this Agreement, describe the nature of the Third
Party Claim in reasonable detail 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 to participate in
or, by giving written notice to the Indemnitee, 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, and the Indemnitee will cooperate in good
faith in such defense.

     (b)  If within thirty (30) days after an Indemnitee provides written
notice to the Indemnifying Party of any Third Party Claim the Indemnitee
receives written notice from the Indemnifying Party that such Indemnifying
Party has elected to assume the defense of such Third Party Claim as provided
in the last sentence of Section 9.2(a), the Indemnifying Party will not be
liable for any legal expenses subsequently incurred by the Indemnitee in
connection with the defense thereof.  If the Indemnifying Party fails to
defend a Third Party Claim actively and in good faith within a reasonable
period of time after receipt of written notice from the Indemnitee to such
effect, specifying that the Indemnitee intends to invoke its rights under this
Section, the Indemnitee may assume the defense of such claim, or compromise or
settle such claim, for the account and risk of the Indemnifying Party, and the
Indemnifying Party will be bound by all such actions of the Indemnitee and
liable for all reasonable expenses thereof.  Without the prior written consent
of the Indemnitee, 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 is
not entitled to indemnification hereunder.  If a firm offer is made to settle
a Third Party Claim without leading to liability or the creation of a
financial or other obligation on the part of the Indemnitee for which the
Indemnitee is not entitled to indemnification hereunder and the Indemnifying
Party desires to accept and agree to such offer, the Indemnifying Party will
give written notice to the Indemnitee to that effect.  If the Indemnitee fails
to consent to such firm offer within ten (10) days after its receipt of such
notice,  

                                   -55-

                                       -195-

<PAGE>

the Indemnitee may continue to contest or defend such Third Party Claim and,
in such event, the maximum liability of the Indemnifying Party as to such
Third Party Claim will be the amount of such settlement offer, plus reasonable
costs and expenses paid or incurred by the Indemnitee up to the date of
such notice.

     (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 reasonably prompt written notice thereof, but
in any event not later than sixty (60) days after the Indemnitee becomes aware
of such claim, stating the nature of such claim in reasonable detail,
specifying this Section of this Agreement and indicating the estimated amount,
if practicable, and the Indemnifying Party will have a period of thirty (30)
days within which to respond to such Direct Claim.  If the 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 rejects
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 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, and otherwise cooperate
in the prosecution of such claims at the direction of the Indemnifying Party. 
Nothing in this Section 9.2(d) shall be construed to require any party hereto
to obtain or maintain any insurance coverage.

     (e)  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.

     (a)  This Agreement may be terminated at any time prior to the Closing
Date by mutual written consent of the Sellers and the Buyer.

     (b)  This Agreement may be terminated by the Sellers or the Buyer if the
Closing contemplated hereby shall have not occurred on or before the first
anniversary of the date of this Agreement (the "Termination Date"); provided
that the right to terminate this Agreement under this Section 10.1(b) shall
not be available to any party whose failure to fulfill any obligation under
this Agreement has been the cause of, or resulted in, the failure of the
Closing to occur on or before such date; and provided, further, that if on the
first anniversary of the date of this Agreement the conditions to the Closing
set forth in Section 8.1(c) shall not have been fulfilled but all other
conditions to the Closing shall be fulfilled or shall be capable of being
fulfilled, then the Termination Date shall be the day which is eighteen months
from the date of this Agreement. 

     (c)  This Agreement may be terminated by either the Sellers or the Buyer
if (i) any governmental or regulatory body, the consent of which is a
condition to the obligations of the Sellers and the Buyer to consummate the
Closing, shall have determined not to grant its or their consent and all
appeals of such determination shall have been taken and have been
unsuccessful, (ii) one or more courts of competent jurisdiction in the United
States or Canada or any state or province shall have issued an order, judgment
or decree permanently restraining, 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 province or federal government or governmental agency in the
United States or Canada which prohibits the consummation of the Closing.

     (d)  This Agreement may be terminated by the Sellers if there has been a
material violation or breach by the Buyer of any agreement, representation or
warranty contained in this Agreement which has rendered the satisfaction of
any condition to the obligations of the Sellers to effect the Closing
impossible and such violation or breach has not been waived by the Sellers. 

     (e)  This Agreement may be terminated by the Buyer if there has been a
material violation or breach by either Seller of any agreement, representation
or warranty contained in this Agreement or in any of the other Closing
Documents which has rendered the satisfaction of any condition to the

or breach has not been waived by the Buyer in writing. 

     (f)  This Agreement may be terminated by either of the Sellers or the
Buyer in accordance with the provisions of Section 7.11(b) or (c).

parties pursuant to Section 10.1, written notice thereof shall forthwith be
given by the terminating party to the other party and this Agreement shall
terminate and the transactions contemplated hereby shall be abandoned, without
further action by any of the parties hereto.  If this Agreement is terminated
as provided herein:

     (a)  Said termination shall be the sole remedy of the parties hereto with
respect to breaches of any agreement, representation or warranty contained in
this Agreement and none of the parties hereto nor any of their respective
trustees, directors, officers or Affiliates, as the case may be, shall have
any liability or further obligation to the other party or any of their
respective trustees, directors, officers or Affiliates, as the case may be,
pursuant to this Agreement, except in each case as stated in this Section 10.2
and in Sections 7.2(b), 7.3 and 7.7; and

     (b)  All filings, applications and other submissions made pursuant to

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 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.

writing and shall be deemed given and received if delivered personally or by
facsimile transmission or mailed by overnight courier or by registered or
