Sault Ste. Marie, Michigan, and Milwaukee, Wisconsin, May 14, 1997

       ESELCO, Inc. (NASDAQ-EDSE) and Wisconsin Energy Corporation (NYSE-WEC)
announced today that they had entered into a definitive agreement regarding the
acquisition of ESELCO, Inc., by WEC.  The terms of the definitive agreement have
been approved by both companies' boards.  Upon completion of the acquisition,
ESELCO, Inc., would continue to operate from Sault Ste. Marie, Michigan.

       All outstanding shares of ESELCO, Inc., common stock would be 
converted into shares of Wisconsin Energy Corporation common stock based on a 
value of $44.50 for each share of ESELCO, Inc., common stock in a transaction 
proposed to be structured as a tax-free reorganization.  The total purchase 
price would be approximately $71 million.  The exact number of shares of 
Wisconsin Energy Corporation common stock to be issued in the transaction 
would be determined by dividing $44.50 by the average closing prices of 
Wisconsin Energy Corporation common stock during the period specified in the 
definitive agreement.  Pursuant to the definitive agreement, Wisconsin Energy 
Corporation will be paid a fee of $2 million if ESELCO, Inc., consummates, or 
enters into an agreement with respect to, a business combination with a party 
unrelated to Wisconsin Energy Corporation or ESELCO, Inc., terminates the 
definitive agreement to pursue a business combination with a party unrelated 
to Wisconsin Energy Corporation prior to the end of the period specified in 
the agreement.

       The transaction is contingent upon several conditions, including the
approval by the shareholders of ESELCO, Inc., receipt of all appropriate
regulatory approvals, and the effectiveness of a registration statement to be
filed with the Securities and Exchange Commission covering the Wisconsin Energy
Corporation shares to be issued in the transaction.  Shareholders of
ESELCO, Inc., will be provided a proxy statement describing the terms of the
transaction prior to being asked to vote on the transaction at a special meeting
of shareholders, which is


                                      2
<PAGE>
expected to take place later in 1997.  There can be no assurance that the 
conditions will be satisfied or that the transaction will be consummated.

       ESELCO, Inc., is the parent corporation of Edison Sault Electric 
Company, an electric utility which serves approximately 22,000 residential, 
commercial and industrial customers located in Michigan's Eastern Upper 
Peninsula.

       Wisconsin Energy Corporation is a holding company with 
subsidiaries in utility and nonutility businesses.  Its principal subsidiary, 
Wisconsin Electric, provides electricity, natural gas, and/or steam service 
to about 2.3 million people in southeastern Wisconsin (including the 
Milwaukee area), the Appleton area, the Prairie du Chien area, and portions 
of northeastern Wisconsin and Michigan's Upper Peninsula.

                  * * * * * * * * * * * * * * * * * * * * *

       The definitive agreement regarding the proposed acquisition is 
incorporated herein by reference and filed as an exhibit to this Form 8-K.

       (b)  As previously disclosed, the Dividend Reinvestment Plan of 
ESELCO, Inc. (the "DRIP") has been suspended pending the acquisition of 
ESELCO, Inc. by Wisconsin Energy Corporation ("WEC").  Pursuant to the 
definitive agreement, all shares of ESELCO, Inc. common stock held in the 
DRIP will continue to be recorded in book-entry form and, subject to earlier 
withdrawal in accordance with the terms of the DRIP, will be held in the DRIP 
until the consummation of the acquisition.  All shares of ESELCO, Inc. common 
stock held in the ESELCO DRIP upon the consummation of the acquisition will 
be converted into shares of WEC common stock on the same terms as the other 
shares of ESELCO common stock as provided in the definitive agreement.  
Participants in the ESELCO, Inc. DRIP may elect to have the whole and 
fractional shares of WEC common stock they receive in the acquisition 
credited to accounts established for them under WEC's dividend reinvestment 
and stock purchase plan, if WEC provides that such an election may be made.

              (b)  CONVERSION.  At the Effective Time of Merger, and without
any action on the part of the holders thereof:

                   (i)  Each share of ESELCO Common Stock issued and
outstanding at the Effective Time of Merger (other than Dissenting ESELCO Stock)
shall be 


                                     -10-
<PAGE>
converted into that number of shares of Wisconsin Energy Common Stock
as is equal to the Exchange Ratio on the terms and conditions set forth in this
Agreement; subject to the provisions of Section 2.8(e) of this Agreement
concerning cash being paid for fractional shares.

                   (ii) Any shares of capital stock of ESELCO that are owned by
any of the ESELCO Companies at the Effective Time of Merger shall be cancelled
and retired and cease to exist and no Wisconsin Energy Common Stock or other
consideration shall be issued or delivered in exchange therefor.

              (c)  DISSENTING ESELCO STOCK.  Notwithstanding anything in this
Agreement to the contrary, shares of ESELCO Common Stock which are outstanding

Stockholders who shall have exercised their dissenter's rights in accordance
with the provisions of Sections 450.1761 through 450.1774 of the Michigan
Business Corporation Act (the "Dissenting ESELCO Stock") shall not be converted
into the right to receive the consideration specified in this Section 2.6 of
this Agreement but shall be cancelled and converted into the right to receive
such consideration as may be determined to be due to the holders of the
Dissenting ESELCO Stock pursuant to the Michigan Business Corporation Act.  If
any holder of Dissenting ESELCO Stock shall, after the Effective Time of Merger,
withdraw or otherwise lose the dissenters rights provided in the Michigan
Business Corporation Act, the Dissenting ESELCO Stock of such holder shall be
deemed to be converted, as of the Effective Time of Merger, into shares of
Wisconsin Energy Common Stock on the terms and conditions set forth in this

         2.8  EXCHANGE OF ESELCO CERTIFICATES.

              (a)  EXCHANGE AGENT.  As of the Effective Time of Merger,
Wisconsin Energy shall act as the exchange agent for, or shall deposit, or shall
cause to be deposited, with a bank or trust company designated by Wisconsin
Energy (in either case, the "Exchange Agent"), for the benefit of the holders of
shares of ESELCO Common Stock, for exchange in accordance with this Article II
of this Agreement through the Exchange Agent, certificates representing the
shares of Wisconsin Energy Common Stock (such certificates for shares of
Wisconsin Energy Common Stock, together with any dividends or distributions with
respect thereto and together with any cash for fractional share interests made

the "Exchange Fund") issuable pursuant to Section 2.6 of this Agreement in
exchange for outstanding shares of ESELCO Common Stock.


                                     -11-
<PAGE>
              (b)  EXCHANGE PROCEDURES.

                   (i)  As soon as reasonably practicable after the Effective
Time of Merger, the Exchange Agent shall mail to each holder of record of a
certificate or certificates which immediately prior to the Effective Time of
Merger represented outstanding shares of ESELCO Common Stock (the "ESELCO
Certificates"):  (A) a letter of transmittal which shall specify that delivery
shall be effected, and risk of loss and title to the ESELCO Certificates shall
pass, only upon delivery of the ESELCO Certificates to the Exchange Agent and
which shall be in such form and have such other provisions as Wisconsin Energy
may reasonably specify; and (B) instructions to effect the surrender of the
ESELCO Certificates in exchange for certificates representing shares of
Wisconsin Energy Common Stock.

                  (ii)  Upon surrender of an ESELCO Certificate for
cancellation to the Exchange Agent together with such letter of transmittal,
duly executed, and with such other documents as the Exchange Agent may
reasonably require, the holder of such ESELCO Certificate shall be entitled to
receive in exchange therefor a certificate representing that number of whole
shares of Wisconsin Energy Common Stock to which such holder is entitled in
respect of such ESELCO Certificate pursuant to the provisions of this Article II
of this Agreement plus any cash in lieu of any fractional share interest in
accordance with Section 2.8(e) of this Agreement, and the ESELCO Certificate so
surrendered shall forthwith be cancelled; provided, however, that fractional
share interests of any one holder shall be aggregated to maximize the number of
whole shares of Wisconsin Energy Common Stock to be issued and minimize the
fractional interests to be paid in cash as provided in Section 2.8(e) of this
Agreement.

                (iii)  In the event of a transfer of ownership of shares of
ESELCO Common Stock which is not registered in the transfer records of ESELCO, a
certificate representing the proper number of shares of Wisconsin Energy Common
Stock may be issued to the transferee if the ESELCO Certificate which
represented such shares of ESELCO Common Stock is presented to the Exchange
Agent, accompanied by all documents required to evidence and effect such
transfer and by evidence that any applicable stock transfer taxes have been
paid.

                 (iv)  Until surrendered as contemplated by this Section 2.8 of
this Agreement, each ESELCO Certificate shall be deemed at all times after the
Effective Time of Merger to represent only the right to receive upon surrender a
certificate representing shares of Wisconsin Energy Common Stock and cash in
lieu of any fractional share interest as contemplated by Section 2.8(e) of this
Agreement.

              (c)  DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES.  No
dividends or other distributions declared or made after the Effective Time of
Merger with respect to Wisconsin Energy Common Stock with a record date after
the Effective Time of Merger shall be paid to the holder of any unsurrendered
ESELCO Certificate with respect to 


                                     -12-
<PAGE>
the shares of Wisconsin Energy Common Stock represented thereby, and no cash 
payment in lieu of a fractional share shall be paid to any such holder 
pursuant to Section 2.8(e) of this Agreement, until the holder of such ESELCO 
Certificate shall surrender such ESELCO Certificate. Subject to the effect of 
any applicable Law, following surrender of any such ESELCO Certificate, there 
shall be paid to the holder of the certificate representing whole shares of 
Wisconsin Energy Common Stock issued in exchange therefor, without interest:  
(i) promptly, the amount of any cash payable with respect to a fractional 
share interest to which such holder is entitled pursuant to Section 2.8(e) of 
this Agreement and the amount of dividends or other distributions with a 
record date after the Effective Time of Merger theretofore paid with respect 
to such whole shares of Wisconsin Energy Common Stock; and (ii) at the 
appropriate payment date, the amount of dividends or other distributions with 
a record date after the Effective Time of Merger but prior to surrender and a 
payment date occurring after surrender payable with respect to such whole 
shares of Wisconsin Energy Common Stock.

              (d)  NO FURTHER RIGHTS IN ESELCO COMMON STOCK.  All shares of
Wisconsin Energy Common Stock issued upon conversion of the ESELCO Common Stock
in accordance with the terms of this Agreement (and any cash paid pursuant to
Section 2.8(e) of this Agreement) shall be deemed to have been issued (and paid)
in full satisfaction of all rights pertaining to the ESELCO Common Stock.

              (e)  NO FRACTIONAL SHARES.  No fractional shares of Wisconsin
Energy Common Stock shall be issued in the Merger.  All fractional share
interests of a holder of more than one ESELCO Certificate at the Effective Time
of Merger shall be aggregated.  If a fractional share interest results after
such aggregation, each holder of a fractional share interest shall be paid an
amount in cash equal to the product obtained by multiplying such fractional
share interest by the Average Wisconsin Energy Price.  As soon as practicable
after the determination of the amount of cash, if any, to be paid to holders of
fractional share interests, the Exchange Agent shall notify Wisconsin Energy and
Wisconsin Energy shall make available such amounts to such holders subject to
and in accordance with the terms of Section 2.8(c) of this Agreement.

              (f)  TERMINATION OF EXCHANGE FUND.  Any portion of the Exchange
Fund which remains undistributed to the ESELCO Stockholders as of a date which
is six months after the Effective Time of Merger shall be delivered to Wisconsin
Energy, upon demand, and any ESELCO Stockholders who have not theretofore
complied with this Article II of this Agreement shall thereafter look only to
Wisconsin Energy for payment of their claim for shares of Wisconsin Energy
Common Stock, any cash in lieu of fractional share interests and any dividends
or distributions with respect to Wisconsin Energy Common Stock.

              (g)  NO LIABILITY.  Neither the Exchange Agent nor any party to
this Agreement shall be liable to any ESELCO Stockholder for any shares of
ESELCO Common Stock or Wisconsin Energy Common Stock (or dividends or
distributions with


                                     -13-
<PAGE>
respect thereto) or cash delivered to a public official pursuant to any 
abandoned property, escheat or similar Law.

              (h)  WITHHOLDING RIGHTS.  Wisconsin Energy shall be entitled to
deduct and withhold from the consideration otherwise payable pursuant to this
Agreement to any ESELCO Stockholder such amounts as Wisconsin Energy is required
to deduct and withhold with respect to the making of such payment under the
Code, or any provision of state, local or foreign tax Law.  To the extent that
amounts are so withheld by Wisconsin Energy, such withheld amounts shall be
treated for all purposes of this Agreement as having been paid to the ESELCO
Stockholder in respect of which such deduction and withholding was made by
Wisconsin Energy.

              (i)  BOOK ENTRY.  Notwithstanding any other provision of this
Agreement, the letter of transmittal referred to in Section 2.8(b) of this
Agreement may, at the option of Wisconsin Energy, provide for the ability of a
holder of one or more ESELCO Certificates to elect that Wisconsin Energy Common
Stock to be received in exchange for the ESELCO Common Stock formerly
represented by such surrendered ESELCO Certificates be issued in uncertificated
form or to elect that such Wisconsin Energy Common Stock be credited to an
account established under the dividend reinvestment and stock purchase plan of
Wisconsin Energy.

         2.9  STOCK TRANSFER BOOKS.  At the Effective Time of Merger, the stock
transfer books of ESELCO shall be closed and there shall be no further
registration of transfers of shares of ESELCO Common Stock thereafter on the
records of ESELCO.  From and after the Effective Time of Merger, the holders of
ESELCO Certificates outstanding immediately prior to the Effective Time of
Merger shall cease to have any rights with respect to such shares of ESELCO
Common Stock except as otherwise provided in this Agreement or by Law.

         2.10 REORGANIZATION; POOLING.  The parties intend that this Agreement
be a plan of reorganization within the meaning of Section 368(a) of the Code and
that the Merger be a tax free reorganization under Section 368(a) of the Code
and that the Merger qualify for pooling of interests accounting treatment.

         2.11 PRIMERGY AGREEMENT.

              (a)  PRIMERGY AGREEMENT.  Wisconsin Energy is a party to the
Primergy Agreement and has delivered to ESELCO a copy of the Primergy Agreement
as in effect on the date of this Agreement, without the Disclosure Schedules and
Exhibits thereto.  Upon the closing of the transactions described in the
Primergy Agreement, Wisconsin Energy shall enter into a business combination
with Northern States Power Company, Wisconsin Energy's name will be changed to
Primergy Corporation and Primergy Corporation will continue to be bound by the
terms of this Agreement.  Except as set forth in Section 2.11(b)


                                     -14-
<PAGE>
 of this Agreement, the closing of the transactions described in the Primergy 
Agreement is not a condition to the Closing of the Merger as described in 
this Agreement.

              (b)  TERMINATION.  Wisconsin Energy may, by notice to ESELCO at
any time prior to the Effective Time of Merger (the "Section 2.11 Notice"),
terminate this Agreement if Wisconsin Energy reasonably concludes in good faith
that this Agreement, the Merger, the Closing of the Merger or the ownership of
the ESELCO Companies by Wisconsin Energy after the Closing of the Merger may
provide a substantial impediment to obtaining, on a timely basis, the regulatory
approvals necessary to close the transactions described in the Primergy
Agreement.

              (c)  TERMINATION FEE.  In order to induce ESELCO to enter into
this Agreement and to compensate ESELCO for the time and expenses incurred in
connection with this Agreement and the Merger and the losses suffered by ESELCO
from foregone opportunities, Wisconsin Energy shall pay the Section 2.11
Termination Fee to ESELCO within five (5) business days after the termination of
this Agreement by Wisconsin Energy pursuant to Section 2.11(b) of this
Agreement.  As used in this Agreement, the "Section 2.11 Termination Fee" shall
be:  (i) if the Section 2.11 Notice is given by Wisconsin Energy after the date
of this Agreement and prior to September 1, 1997, the amount of $3,000,000; 
(ii) if the Section 2.11 Notice is given by Wisconsin Energy on or after
September 1, 1997 and prior to November 1, 1997, the amount of $4,000,000;

(iv) if the Section 2.11 Notice is given by Wisconsin Energy on or after 
January 1, 1998, the amount of $7,500,000.

              (d)  TERMINATION OF SECTION 3.8.  If Wisconsin Energy terminates
this Agreement pursuant to Section 2.11(b) of this Agreement, all obligations of
ESELCO under Section 3.8 of this Agreement shall immediately and completely
terminate as of the date of such termination.

deemed by Wisconsin Energy to be unduly burdensome.  Each party to this 
Agreement will furnish to the other parties all information concerning itself

Disclosure Schedule made by ESELCO which, in the reasonable judgment of

terminate this Agreement.  If Wisconsin Energy does not terminate this Agreement
pursuant to this Section 3.4(b) of this Agreement, the relevant Disclosure

Wisconsin Energy shall no longer have any right to terminate this Agreement
based on such Disclosure Schedule Changes except to the extent otherwise

Effective Time of Merger.  Such indemnification shall be in accordance with, and
substantially equivalent to, the indemnification provided from time to time by
Subsidiaries of Wisconsin Energy to employees, agents, directors and officer of
Subsidiaries of Wisconsin Energy.

              (b)  INSURANCE.  For at least three (3) years from and after the

         3.15 EMPLOYMENT MATTERS.

              (a)  EDISON SAULT MANAGEMENT PENSION PLAN.  Within a reasonable
period of time after the Effective Time of Merger, Wisconsin Energy shall cause
the Pension Plan for Management Employees of Edison Sault (the "Edison Sault
Management Plan") to be merged into the Wisconsin Electric Power Company
Retirement Account Plan (the 


                                     -22-
<PAGE>
"Retirement Account Plan") and the Retirement Account Plan to be amended to 
provide that employees of Edison Sault who were covered under the Edison 
Sault Management Plan and who became covered under the Retirement Account 
Plan by reason of such merger and who subsequently terminate on or prior to 
December 31, 2010 with a 100% fully vested interest shall be entitled to an 
accrued pension benefit not less than what they would have received had the 
provisions of the Edison Sault Management Plan as in existence as of the 
Effective Time of Merger continued to apply to them (except that Wisconsin 
Energy reserves the right to provide all or part of such accrued pensions 
benefits by means of a non-qualified pension plan to the extent necessary to 
maintain, in the reasonable judgment of Wisconsin Energy, the tax qualified 
status of the Retirement Account Plan).

              (b)  EDISON SAULT EMPLOYEE INCENTIVE INVESTMENT AND STOCK
OWNERSHIP PLAN.  Within a reasonable period of time after the Effective Time of
Merger, Wisconsin Energy shall cause the Employee Incentive Investment and Stock
Ownership Plan of Edison Sault to be merged into the Wisconsin Electric Power
Company Employees Savings Plan and shall extend such Savings Plan to the
employees of the ESELCO Companies.

              (c)  SPECIAL EARLY RETIREMENT WINDOW PROGRAM.  Prior to or after
the Effective Time of Merger, but prior to the merger of any defined benefit
pension plan of Edison Sault which is used in connection with a special
voluntary early window program, Edison Sault may proceed with a special
voluntary early retirement window program in accordance with the program
described in the Disclosure Schedule.

              (d)  SEVERANCE AGREEMENTS.  After the Effective Time of Merger,
Wisconsin Energy shall cause Edison Sault to honor all obligations which may be
incurred by Edison Sault under the nine Executive Severance Agreements
identified on the Disclosure Schedule, subject to the terms thereof, which would
cause such obligations to expire regarding any individual who elected a special
early retirement benefit under the program described in Section 3.15(c) of this
Agreement.

              (e)  COMPANY CARS.  After the Effective Time of Merger, Wisconsin
Energy will cause the ESELCO Companies to continue a company car policy with
respect to those employees who are determined from time-to-time to have an
operational need therefor and regarding the other individuals who are currently
provided with company cars as of the Effective Time of Merger, to allow them to
either continue to use the same until the end of the useful life thereof, with
an option at the end of such useful life to buy the same at the lower of book or
market value, or to elect to discontinue use of the same and receive such
increase in compensation as is determined to be appropriate in the sole
discretion of the employer.

              (f)  RETIREE HEALTH CARE PLAN.  After the Effective Time of
Merger, Wisconsin Energy will cause the retiree health care program then in
effect at the ESELCO Companies (the "ESELCO Retiree Health Plan") to be
continued, subject to and in 


                                     -23-
<PAGE>
accordance with its terms (including any reserved right to amend or terminate 
the same), with respect to individuals who were already retired at such time 
and with respect to those who retire or otherwise terminate from the service 
of the ESELCO Companies in such manner as to entitle them to benefit from 
such program, until at least one year from the Effective Time of Merger (the 
"Changeover Date"), with such individuals (both those already retired and 
those who subsequently retire) to pay forty-five percent (45%) of the cost 
thereof, except for the classes of individuals identified in the Disclosure 
Schedule who will only be obligated to pay forty percent (40%). From the 
Changeover Date until December 31, 2004 (the "Extended Period"), Wisconsin 
Energy will cause the ESELCO Companies to continue the same program of 
benefits and, at least for purposes of measuring retiree contributions, at 
the same total premium costs, with both such benefits and costs to be subject 
to change from time to time as would occur pursuant to the underlying health 
insurance contracts in effect immediately prior to the Changeover Date 
(whether or not those insurance contracts are actually continued in force), 
and retiree contributions shall be fifty percent (50%) of such costs.  During 
the Extended Period, Wisconsin Energy may in its discretion cause the ESELCO 
Companies to provide such benefits either by a continuation of the health 
insurance contracts in effect immediately prior to the Changeover Date under 
the ESELCO Retiree Health Plan, use of a self-insured arrangement, or 
otherwise.

              (g)  OTHER BENEFITS.  Within a reasonable period of time after
the Effective Time of Merger and subject to the collective bargaining
obligations of Edison Sault, Wisconsin Energy shall cause other benefit plans
and programs substantially similar to those in effect at Wisconsin Electric
Power Company for employees generally (including severance benefits) to be
extended to employees of the ESELCO Companies and shall extend past service
credit for purposes of eligibility to participate, vesting and benefit accruals
under such benefit plans and programs for service with the ESELCO Companies
before the Effective Time of Merger, provided that such crediting of service
shall not operate to duplicate any benefit or the funding of any benefit, and
provided further that any vacation entitlements in existence at the Effective
Time of Merger under any policy of the ESELCO Companies with respect to officers
shall not be decreased after the Effective Time of Merger.  

              (h)  RELOCATION EXPENSES FOR TRANSFERRED MANAGEMENT EMPLOYEES. 
Wisconsin Energy will cause the ESELCO Companies to establish a special
relocation expense reimbursement plan for such of the management employees of
Edison Sault as are requested to relocate as a result of the transactions
described in this Agreement substantially similar to such program as may then be
in effect at Wisconsin Electric Power Company. 

              (i)  SERP.  Edison Sault shall take all necessary actions to
terminate the Supplemental Executive Retirement Plan of Edison Sault Electric
Company (the "SERP"), as of the Effective Time of Merger and shall continue to
remain obligated to pay benefits in the amount earned under the SERP as of the
termination date to those participants who would be eligible to receive benefits
if their employment had been then terminated.  Edison Sault shall obtain the
consent of each other current participant who may have earned 


                                     -24-
<PAGE>
benefits under the SERP but who would not be eligible to receive such 
benefits if his employment had terminated on the date of termination of the 
SERP to receipt of an immediate single lump sum distribution of reasonably 
equivalent actuarial value in lieu of and in complete satisfaction of any 
other obligation to such individual under the SERP (with such lump sum to be 
increased to take into account the tax impact thereof, assuming the maximum 
combined federal, Michigan and employee Medicare tax rates in effect as of 
the Effective Time of Merger, net of the federal income tax benefit of the 
state tax, the intent of such increase being to leave each such individual 
with an amount which, after payment of such taxes under the assumption above, 
would be equal to such single lump sum distribution.

              (j)  DIRECTOR'S RETIREMENT PLAN.  ESELCO shall take all necessary
actions to terminate the ESELCO, Inc. Director's Retirement Plan (the "ESELCO
Director Plan") as of the Effective Time of Merger.  After the Effective Time of
Merger, Wisconsin Energy shall cause ESELCO to continue to honor all obligations
under the ESELCO Director Plan as in effect at such termination.

              (k)  DIRECTOR'S FEE DEFERRAL PLANS.  (i)  With respect to the
Edison Sault Electric Company Director's Fee Deferral Plan effective as of
October 1, 1989 (the "1989 Fee Deferral Plan"), ESELCO shall cause Edison Sault
to take all necessary actions to discontinue recognizing further fee deferrals
and to amend such Plan as of the Effective Time of Merger as follows:

    (A)  to provide that all future earnings on the deferred fee account
         balances will be identical to the interest rates or other methods
         allowed to participants under the Wisconsin Energy Directors' Deferred
         Compensation Plan (the "Wisconsin Energy Directors' Plan") from time
         to time;

    (B)  to eliminate Section B(17) of Article I and Section B(3) of
         Article III; and

    (C)  to make the methods of payment identical to the methods allowed to
         participants and beneficiaries under the Wisconsin Energy Directors'
         Plan.

ESELCO shall also cause Edison Sault to take all necessary actions,
simultaneously with the foregoing amendments, to terminate the 1989 Fee Deferral
Plan as of the Effective Time of Merger.  After the Effective Time of Merger,
Wisconsin Energy shall cause Edison Sault to continue to honor all obligations
under the 1989 Fee Deferral Plan, as so amended and as in effect at such
termination.  

         (ii)  With respect to the Edison Sault Electric Company ESELCO
Director's Fee Deferral Plan as of January 1, 1986 (the "1986 Fee Deferral
Plan"), ESELCO shall cause Edison Sault to take all necessary actions to
discontinue recognizing further fee deferrals and to amend such Plan as of the
Effective Time of Merger to eliminate Section B(17) of Article I and 
Section B(3) of Article III.  ESELCO shall also cause Edison Sault to take all
necessary actions, simultaneously with the foregoing amendments, to terminate
the


                                     -25-
<PAGE>
1986 Fee Deferral Plan, as of the Effective Time of Merger.  After the 
Effective Time of Merger, Wisconsin Energy shall cause Edison Sault to 
continue to honor all obligations under the 1986 Fee Deferral Plan, as so 
amended and as in effect at such termination.

              (l)  LABOR AGREEMENTS.  Prior to and after the Effective Time of
Merger, Edison Sault shall, and after the Effective Time of Merger, Wisconsin
Energy shall cause Edison Sault to, continue to honor all collective bargaining
agreements to which it is a party, subject to the terms thereof, it being
acknowledged that the current collective bargaining agreements in effect as of
the date of execution of this Agreement expire on October 21, 1998.

         9.9  COUNTERPARTS; HEADINGS.  This Agreement may be executed in 
several counterparts, each of which shall be deemed an original, but such 
counterparts shall together constitute but one and the same Agreement.  The 
Table of Contents and Article and Section headings in this Agreement are 
inserted for convenience of reference only and shall not constitute a part 
hereof.

         9.10 INTERPRETATION.  Unless the context requires otherwise, all

include the plural, all words in the plural number shall extend to and 
include the singular, and all words in any gender shall

extend to and include all genders.  The language used in this Agreement shall 
be deemed to be language chosen by the parties to this Agreement to express 
their mutual intent.  In the event an ambiguity or question of intent or 
interpretation arises concerning the language of this Agreement, this 
Agreement shall be construed as if drafted jointly by the parties to this 
Agreement and no presumption or burden of proof will arise favoring or 
disfavoring any party to this Agreement by virtue of the authorship of any of 
the provisions of this Agreement.

         9.11 SEVERABILITY.  If any provision, clause, or part of this 
Agreement, or the application thereof under certain circumstances, is held 
invalid, the remainder of this Agreement, or the application of such

to consummate the transactions contemplated by this Agreement.

         9.12 SPECIFIC PERFORMANCE.  The parties agree that the assets and
business of the ESELCO Companies as a going concern constitute unique property. 
There is no adequate remedy at Law for the damage which any party might sustain
for failure of the other parties to consummate the Merger and the transactions
contemplated by this Agreement, and accordingly, each party shall be entitled,
at its option, to the remedy of specific performance to enforce the Merger
pursuant to this Agreement.

         9.13 NO RELIANCE.  Except for the parties to this Agreement and any 
assignees permitted by Section 9.7 of this Agreement: (a) no Person is

warranties and agreements of the parties contained in this Agreement.

the necessity of specific repetition or cross-reference.  All capitalized 
terms used in any Exhibit to this Agreement or in the Disclosure Schedule 
shall have the definitions specified in this Agreement.

         9.15 FURTHER ASSURANCES.  If, at any time after the Effective Time 
of Merger, any further action is necessary or desirable to carry out the 
purposes of this Agreement and to vest the Surviving Corporation with full 
right, title and possession to all assets, properties, rights, privileges, 
powers and franchises of either Acquisition or ESELCO, the officers of the 
Surviving Corporation are fully authorized to take any such action in the 
name of Acquisition or ESELCO.
