(1)  Assumes  that up  to 70,330,635 shares  of common stock  of Northern States
     Power Company  ("NSP")  are  converted  into  shares  of  Wisconsin  Energy
     Corporation  ("WEC") common stock at the  exchange ratio of 1.626 shares of
     WEC common stock for each share of NSP common stock pursuant to the Amended
     and Restated Agreement and Plan of Merger (the "Merger Agreement") to which
     this registration statement relates. In connection with the consummation of
     the transactions provided for in the Merger Agreement, WEC will change  its
     name to Primergy Corporation ("Primergy").
(2)  Estimated  pursuant to Rules 457(f)(l) and  457(c) under the Securities Act
     of 1933 solely for the purpose  of calculating the registration fee,  based
     on  $43.9375 per share, the  average of the high and  low sale prices for a
     share of NSP common stock on the New York Stock Exchange Composite Tape  on
     August  3,  1995. The  proposed maximum  offering price  per unit  has been
     determined by dividing the proposed maximum aggregate offering price by the
     number of shares being registered, rounded to the nearest cent.
(3)  Includes the fee of $656,138.50 paid to the Commission on June 7, 1995 upon
     filing the preliminary proxy  materials of WEC and  NSP and the  additional
     fee  of $1,453 paid on July 14, 1995 upon the filing of amended preliminary
     proxy materials. Pursuant to  Rule 457(b), the  $407,978.25 balance of  the
     registration  fee  is  being  paid  to  the  Commission  upon  filing  this
     registration statement.
(4)  To the extent that less than the maximum number of shares registered hereby
     are issued  pursuant to  the  Merger Agreement,  it  is intended  that  the
     balance  of the registered  shares will be utilized  in connection with NSP
     stock plans assumed pursuant to the Merger Agreement, by filing one or more
     post-effective amendments hereto on the appropriate registration form  with
     respect to such plans.

                                                                  August 7, 1995

Dear NSP Shareholder:

    You  are cordially invited  to attend the Annual  Meeting of Shareholders of
Northern States Power Company,  a Minnesota corporation  ("NSP"), which will  be
held  on Wednesday,  September 13, 1995,  at the  Minneapolis Convention Center,
1301 South  Second Avenue,  Minneapolis, Minnesota  55463, Exhibit  Hall I.  The
meeting will start at 10:00 a.m., local time.

    At  this important meeting, the NSP shareholders  will be asked to approve a
merger agreement  (the  "Merger  Agreement") relating  to  a  "merger-of-equals"
transaction  with Wisconsin Energy Corporation, a Wisconsin corporation ("WEC").
As a result of the mergers contemplated by the Merger Agreement (the "Mergers"),
Primergy Corporation ("Primergy") will  become the holding  company for NSP  and
the  operating subsidiaries of WEC. The headquarters of Primergy will be located
in Minneapolis. Pursuant to the Merger Agreement, each outstanding share of  NSP
common  stock  will be  cancelled  and ultimately  converted  into the  right to
receive  1.626  shares  (the  "Ratio")  of  Primergy  common  stock,  and   each
outstanding  share of NSP  preferred stock will be  cancelled and converted into
preferred stock of the successor entity to NSP, incorporated in Wisconsin,  with
identical terms (including dividend rates) and designations.

    Your  Board of Directors believes that this "merger-of-equals" will create a
combined enterprise  well  positioned  for an  increasingly  competitive  energy
industry  environment,  benefiting  not only  shareholders  but  also customers,
employees and  the  communities  served by  our  respective  utility  companies.
Meaningful  strategic advantages that Primergy  will possess include substantial
cost savings  from,  among  other  things,  decreased  fuel  costs  and  reduced
corporate  and administrative expense, and implementation of a rate reduction to
be followed  by  a  rate  freeze  through the  year  2000  for  retail  electric
customers.  Primergy will  also enjoy  increased financial  strength as  well as
greater opportunities for earnings  and dividend growth  through the pooling  of
NSP's and WEC's equity, management, human resources and technical expertise.

    Based  on the  capitalization of NSP  and WEC as  of the date  of the Merger
Agreement, the common shareholders  of NSP and  WEC would each  as a group  have
held  approximately 50% of the  shares of Primergy common  stock that would have
been outstanding if the Mergers had been consummated as of such date. Your Board
of Directors has received the opinion of its financial advisor, Goldman, Sachs &
Co., that  as of  the  date hereof  and based  on  the factors  and  assumptions
described in such opinion, the Ratio is fair to the holders of NSP common stock.

    Approval  of the Merger Agreement by shareholders of NSP and WEC entitled to
vote thereon  is  a  condition  to the  consummation  of  the  transaction.  The
transaction  will  be consummated  only after  certain regulatory  approvals are
received  and  other  conditions  are  satisfied  or  waived.  It  is  presently
anticipated that this will occur in the last quarter of 1996.
<PAGE>

    YOUR  BOARD OF DIRECTORS HAS CAREFULLY REVIEWED AND CONSIDERED THE TERMS AND
CONDITIONS OF THE MERGER AGREEMENT, BELIEVES THAT THEY ARE IN THE BEST INTERESTS
OF NSP AND ITS SHAREHOLDERS, HAS  UNANIMOUSLY APPROVED THE MERGER AGREEMENT  AND
RECOMMENDS A VOTE FOR APPROVAL OF THE MERGER AGREEMENT.

    At  the Annual Meeting,  you will also  be asked to  consider and vote upon:
certain employee plans proposed to be  implemented by Primergy; the election  of
four  directors to Class III to serve on the NSP Board of Directors for terms of
three years until their successors  are elected and qualified; the  ratification
of  the appointment of Price Waterhouse LLP as NSP's independent accountants for
1995; and  two shareholder  proposals. As  described in  the accompanying  Joint
Proxy  Statement/Prospectus, at the effective time  of the Mergers, the Primergy
Board of Directors will  consist of 12  members, six of  whom will be  directors
appointed  by  the NSP  Board of  Directors and  six of  whom will  be directors
appointed by the WEC Board of Directors.

    YOUR BOARD OF DIRECTORS ALSO RECOMMENDS A  VOTE FOR THE APPROVAL OF EACH  OF
THE  PRIMERGY  EMPLOYEE PLANS,  FOR  THE PROPOSED  SLATE  OF DIRECTORS,  FOR THE
RATIFICATION OF THE APPOINTMENT OF  INDEPENDENT ACCOUNTANTS AND AGAINST THE  TWO
SHAREHOLDER PROPOSALS AT THE ANNUAL MEETING.

    Your  vote is important no matter how many shares you hold. Even if you plan
to attend the meeting, we urge you to mark, sign and date the enclosed proxy and
return it promptly. You  have the option to  revoke it at any  time, or to  vote
your  shares personally  on request  if you attend  the meeting.  For the Merger
Agreement to be approved, it must have the support of the majority of the  votes
entitled  to  be cast  by the  outstanding shares  of NSP  common stock  and NSP
preferred stock entitled to vote, voting as a single class.

    IF YOU DO NOT RETURN THE PROXY CARD AND DO NOT VOTE AT THE MEETING, IT  WILL
HAVE THE SAME EFFECT AS IF YOU VOTED AGAINST THE MERGER AGREEMENT.

    The  accompanying  Joint Proxy  Statement/Prospectus  sets forth  the voting
rights of  holders of  NSP common  and  preferred stock  with respect  to  these
matters,  and describes  the matters  to be  acted upon  at the  Annual Meeting.
Shareholders  are  urged   to  review   carefully  the   attached  Joint   Proxy
Statement/Prospectus,  which  contains  a  detailed  description  of  the Merger
Agreement, the terms  and conditions thereof  and the transactions  contemplated
thereby.  If the  Mergers are consummated,  holders of NSP  common and preferred
stock who wish to assert such rights and have complied with the requirements  of
the  Minnesota  Business Corporation  Act will  have certain  dissenters' rights
under Minnesota law, as described in more detail in the accompanying Joint Proxy
Statement/ Prospectus.

    Promptly after the Mergers, a letter  of transmittal will be mailed to  each
holder  of record  of shares of  NSP common stock.  PLEASE DO NOT  SEND YOUR NSP
COMMON STOCK CERTIFICATES WITH THE ENCLOSED PROXY CARD OR TO THE EXCHANGE  AGENT
UNLESS  AND  UNTIL YOU  RECEIVE THE  LETTER OF  TRANSMITTAL, WHICH  WILL INCLUDE
INSTRUCTIONS AS TO THE  PROCEDURE TO BE  USED IN SENDING  YOUR NSP COMMON  STOCK
CERTIFICATES.  Holders of  NSP preferred stock  will not have  to exchange their
stock certificates as a result of the Mergers.

                                          Sincerely,

                                                         [SIG]

Dear Wisconsin Energy Corporation Stockholder:

A Special Meeting of Stockholders will be held at 9:00 A.M. on WEDNESDAY,
SEPTEMBER 13, 1995 in the Exhibition Hall of The Grand Milwaukee Hotel, 4747
South Howell Avenue, Milwaukee, Wisconsin. The purpose of this meeting is to
vote on proposals relating to the strategic business combination between your
Company and Minneapolis-based Northern States Power Company (NSP).

YOUR BOARD OF DIRECTORS HAS CAREFULLY REVIEWED AND CONSIDERED THE TERMS AND
CONDITIONS OF THE MATTERS TO BE VOTED UPON AND BELIEVES THAT THEY ARE IN THE
BEST INTERESTS OF WEC AND ITS STOCKHOLDERS AND UNANIMOUSLY RECOMMENDS THAT
STOCKHOLDERS VOTE "FOR" EACH OF THE PROPOSALS DESCRIBED IN THE ATTACHED JOINT
PROXY STATEMENT.

Your Board believes that this "merger of equals" will create a combined
enterprise that will be well-positioned for an increasingly competitive energy
environment. The combined enterprise will be called Primergy ("Prime-er-gee")
Corporation. Strategic advantages that Primergy will possess include substantial
cost savings from decreased fuel cost and reduced corporate/administrative
expense, and competitive benefits of a proposed retail electric rate reduction
to be followed by a freeze through the year 2000. Primergy will also enjoy
increased financial strength as well as greater opportunities for earnings and
dividend growth through the pooling of WEC's and NSP's equity, management, human
resources and technical expertise.

Upon completion of the merger, each share of WEC common stock you own will
represent one share of Primergy common stock. As a WEC stockholder, YOU WILL NOT
NEED TO EXCHANGE YOUR WEC STOCK CERTIFICATES. The exchange ratio has been set so
that common stockholders of WEC and NSP would each own approximately 50% of the
outstanding shares of Primergy common stock based upon the capitalization of WEC
and NSP on the date of the merger agreement. This means that NSP common
stockholders will receive 1.626 shares of Primergy common stock in exchange for
each share of NSP common stock they own. Your Board has received the opinions of
its financial advisor, Barr Devlin & Co. Incorporated, to the effect that the
exchange ratio of 1.626 is fair, from a financial point of view, to the holders
of WEC common stock.
<PAGE>
In connection with the merger, you are also being asked to approve certain
changes to the Restated Articles of Incorporation and to approve certain stock
incentive and management incentive compensation plans. The Articles changes are
necessary to effect the change of the name of your Company to Primergy
Corporation and to ensure that Primergy will have the flexibility to issue stock
when the need arises without the delay of having to obtain shareholder approval
to authorize the issuance if not otherwise required. The incentive plans are
intended to replace the comparable existing WEC and NSP plans and will provide
management with incentives directly linked to the profitability of Primergy's
businesses and increases in stockholder value.

Each of the proposals is more fully described in the accompanying Notice and
Joint Proxy Statement/Prospectus and its various attachments. I encourage you to
study these materials carefully. This is an important transaction that requires
many issues to be considered and agreed upon.

This strategic business combination is subject to your approval as well as the
approval of NSP stockholders. AS NOTED ABOVE, YOUR BOARD RECOMMENDS A VOTE "FOR"
EACH PROPOSAL PRESENTED. The combination is also subject to certain required
regulatory approvals and other conditions. If all required approvals are
received, it is presently anticipated that the transaction will be effective in
the last quarter of 1996.

YOUR VOTE IS IMPORTANT NO MATTER HOW MANY SHARES YOU HOLD. TO ENSURE YOUR SHARES
WILL BE REPRESENTED AT THE MEETING, WHETHER OR NOT YOU PLAN TO ATTEND, I URGE
YOU TO PROMPTLY COMPLETE AND MAIL YOUR PROXY IN THE ENCLOSED ENVELOPE. You may
cancel your proxy before the meeting and vote in person if you wish.

If  you  have  any  questions  about  the  meeting,  please  call  our toll-free
Stockholder Hotline at 1-800-558-9663.

Sincerely,

       [SIG]

accompanying Joint Proxy Statement/Prospectus:

        1.  A proposal to approve the Amended and Restated Agreement and Plan of
    Merger,  dated as of April 28, 1995, as  amended and restated as of July 26,
    1995 (the  "Merger Agreement"),  by  and among  WEC, Northern  States  Power
    Company,  a  Minnesota  corporation  ("NSP"),  WEC  Sub  Corp.,  a Wisconsin
    corporation and wholly-owned subsidiary of WEC, and Northern Power Wisconsin
    Corp., a Wisconsin corporation and wholly-owned subsidiary of NSP, a copy of

    Statement/Prospectus,  and the transactions  contemplated thereby including,
    among other things, the  issuance of shares  of common stock  of WEC (to  be
    renamed  Primergy  Corporation ("Primergy"))  pursuant to  the terms  of the
    Merger Agreement;

        2.  A  proposal to  approve the amendment  to and  restatement of  WEC's
    Restated  Articles  of Incorporation  so as  to  change the  name of  WEC to
    Primergy Corporation (the "Name Change  Amendment"), as provided for in  the

    authorized common  stock  of  WEC from  325,000,000  shares  to  750,000,000
    shares,  thereby increasing WEC's authorized capitalization from 340,000,000

    preferred  stock presently  authorized) (the  "Common Stock  Amendment" and,
    together with the Name Change Amendment, the "WEC Articles Amendments"),  as
    provided  for in the Restated Articles of Incorporation of Primergy attached
    as Annex H to the accompanying Joint Proxy Statement/Prospectus;

        4.  A proposal to approve the  Primergy Stock Incentive Plan, a copy  of

    Shareholders  of record at  the close of  business on July  27, 1995 will be
entitled to notice of and to vote  at the Special Meeting or at any  adjournment
or  postponement thereof. Approval  of the Merger  Agreement, the Primergy Stock
Incentive  Plan  and  the   Primergy  Management  Incentive  Compensation   Plan
(collectively,  the  "Primergy  Plans")  requires the  affirmative  vote  of the
holders of a  majority of  the shares  of WEC  common stock  represented at  the
Special  Meeting  and entitled  to  vote thereon.  Approval  of the  Name Change
Amendment and the Common  Stock Amendment requires the  affirmative vote of  the
holders  of a majority of the outstanding shares of WEC common stock entitled to
vote thereon. WEC shareholders are not entitled to dissenters' rights.

    Approval of proposals 1 through 5 are conditions to the consummation of  the
transactions  contemplated by the Merger Agreement. If approved by shareholders,
each of  the WEC  Articles Amendments  will become  effective, and  each of  the
Primergy Plans will be implemented, only if the transactions contemplated by the
Merger Agreement are consummated.

    YOUR  BOARD OF DIRECTORS HAS UNANIMOUSLY  APPROVED THE MERGER AGREEMENT, THE
NAME CHANGE AMENDMENT, THE COMMON STOCK AMENDMENT, THE PRIMERGY STOCK  INCENTIVE

  PRIMERGY CORPORATION                                               NORTHERN STATES POWER COMPANY
</TABLE>

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

    This  Joint Proxy Statement/Prospectus  relates to (i)  the proposed mergers
and certain  related  transactions  contemplated by  the  Amended  and  Restated
Agreement  and  Plan of  Merger,  dated as  of April  28,  1995, as  amended and
restated as of  July 26, 1995  (the "Merger Agreement"),  by and among  Northern
States   Power  Company,  a  Minnesota  corporation  ("NSP"),  Wisconsin  Energy
Corporation, a Wisconsin corporation ("WEC"), Northern Power Wisconsin Corp.,  a
Wisconsin  corporation and a wholly-owned subsidiary of NSP ("New NSP"), and WEC
Sub Corp., a Wisconsin  corporation and a wholly-owned  subsidiary of WEC  ("WEC
Sub")  and (ii) in the case of NSP,  the election of directors and certain other
matters. Upon consummation of the mergers provided for in the Merger  Agreement,
WEC (which will be renamed Primergy Corporation ("Primergy") at or prior to such
time)  will be the holding  company of both NSP  (which, for regulatory reasons,
will  reincorporate  in  Wisconsin)  and  the  operating  subsidiaries  of  WEC,
including  Wisconsin Electric Power Company,  a Wisconsin corporation ("WEPCO").
Primergy will be  registered under  the Public  Utility Holding  Company Act  of
1935,  as amended (the  "1935 Act"). See  "Regulatory Matters." As  used in this
Joint Proxy Statement/Prospectus, "Primergy" shall  refer to WEC from and  after
the effective time of the mergers provided for in the Merger Agreement.

    The  Merger Agreement provides for: (i) the  merger of NSP with and into New
NSP (the  "Reincorporation  Merger")  pursuant  to which  (a)  each  issued  and
outstanding  share of  common stock,  par value  $2.50 per  share, of  NSP ("NSP
Common Stock") (except shares held  by NSP shareholders who perfect  dissenters'
rights  with respect  thereto ("NSP Dissenting  Shares")) will  be cancelled and
converted into one share of common stock, par value $2.50 per share, of New  NSP
("New NSP Common Stock") and (b) each issued and outstanding share of cumulative
preferred  stock,  par value  $100  per share,  of  NSP ("NSP  Preferred Stock")
(except NSP Dissenting Shares) will be cancelled and converted into one share of
cumulative preferred  stock, par  value $100  per share,  of New  NSP ("New  NSP
Preferred  Stock") with terms (including  dividend rates) and designations under
New NSP's Articles of Incorporation (the "New NSP Articles") identical to  those
of  the cancelled  share of  NSP Preferred  Stock under  NSP's existing Restated
Articles of Incorporation (the "NSP Articles");  and (ii) the merger of WEC  Sub
with  and  into New  NSP (the  "NSP Merger";  together with  the Reincorporation
Merger, the "Mergers") pursuant to which  (a) each issued and outstanding  share
of New NSP Common Stock will be cancelled and converted into 1.626 (the "Ratio")
shares  of common stock, par value $.01 per share, of Primergy ("Primergy Common
Stock") and (b)  each issued and  outstanding share of  New NSP Preferred  Stock
will remain outstanding and shall be unchanged thereby (except for any shares of
New NSP Common Stock and New NSP Preferred Stock owned directly or indirectly by
New  NSP or  WEC, which will  be cancelled and  will not be  converted or remain
outstanding). Each issued and outstanding share of common stock, par value  $.01
per  share, of WEC  ("WEC Common Stock") will  remain outstanding, unchanged, as
one share of Primergy Common Stock. Based upon the capitalization of WEC and NSP
on April 28,  1995 and the  Ratio, holders of  WEC Common Stock  and NSP  Common
Stock  would each have held approximately 50%  of the aggregate number of shares
of Primergy Common  Stock that would  have been outstanding  if the Mergers  had
been consummated as of such date.

                  SUMMARY OF JOINT PROXY STATEMENT/PROSPECTUS

    THE  FOLLOWING IS A SUMMARY OF CERTAIN IMPORTANT TERMS AND CONDITIONS OF THE
MERGERS AND RELATED INFORMATION.  THIS SUMMARY DOES NOT  PURPORT TO BE  COMPLETE
AND  IS QUALIFIED IN ITS ENTIRETY BY  REFERENCE TO THE MORE DETAILED INFORMATION
APPEARING  IN  THIS  JOINT  PROXY  STATEMENT/PROSPECTUS,  THE  ANNEXES  AND  THE
DOCUMENTS  INCORPORATED HEREIN BY REFERENCE. SHAREHOLDERS ARE URGED TO READ THIS
JOINT PROXY STATEMENT/PROSPECTUS AND THE ANNEXES IN THEIR ENTIRETY.

THE PARTIES

    PRIMERGY.  The WEC Articles will  be amended and restated immediately  prior
to  or upon consummation of the Mergers  to, among other things, change the name
of WEC to "Primergy Corporation." Primergy  will be the holding company for  New
NSP  and the operating subsidiaries of  WEC following the Mergers. Primergy will
be a  public  utility  holding  company  registered  under  the  1935  Act.  See
"Regulatory  Matters"  and  "Primergy  Following  the  Mergers."  The  principal
executive office of Primergy will be located at 414 Nicollet Mall,  Minneapolis,
Minnesota 55401, telephone number (612) 330-2930.

    WEC.   WEC is a  holding company whose principal  subsidiaries are WEPCO, an
electric utility, and Wisconsin Natural  Gas Company, a gas utility  ("Wisconsin
Natural").  WEPCO generates, transmits, distributes and sells electric energy in
a territory of approximately 12,000 square miles with a population estimated  at
over  2,200,000 in southeastern (including the Milwaukee area), east central and
northern  Wisconsin  and  in  the  Upper  Peninsula  of  Michigan.  WEPCO   also
distributes  and sells  steam supplied  by one  of its  power plants  to certain
customers in  Milwaukee.  Wisconsin  Natural purchases,  distributes  and  sells
natural  gas  to retail  customers and  transports  customer-owned gas  in three
distinct service areas in  Wisconsin: west and south  of the City of  Milwaukee;
the  Appleton area; and  the Prairie du Chien  area. Wisconsin Natural's service
territory has an estimated  population of over 1,100,000  and is largely  within
the   electric  service  area  of  WEPCO.   WEC  also  has  certain  non-utility
subsidiaries. Prior to or upon the consummation of the Mergers, WEPCO's Restated
Articles of  Incorporation  will be  amended  to change  the  name of  WEPCO  to
"Wisconsin  Energy Company." The principal executive office of WEC and WEPCO is,
and the  principal  executive  office  of Wisconsin  Energy  Company  after  the
Effective Time (as defined herein) will be, located at 231 West Michigan Street,
P.O.  Box 2949, Milwaukee, Wisconsin 53201, telephone number (414) 221-2345. See
"Selected Information Concerning WEC and NSP  -- Business of WEC" and  "Primergy
Following the Mergers -- Operations."

    NSP.   NSP is predominantly an  operating public utility engaged, along with
its most  significant subsidiary,  Northern States  Power Company,  a  Wisconsin
corporation  ("NSP-Wisconsin"), in the generation, transmission and distribution
of electricity throughout a 49,000 square mile service area and the distribution
of natural gas  in approximately 148  communities within this  area. NSP  serves
customers  in Minnesota, North  Dakota and South  Dakota. NSP-Wisconsin provides
electric and natural gas utility service to customers in Wisconsin and the Upper
Peninsula of Michigan. Of the approximately  3,000,000 people served by NSP  and
NSP-Wisconsin,  the  majority  are  concentrated  in  the  Minneapolis-St.  Paul
metropolitan area.  NSP  has several  other  subsidiaries including  Viking  Gas
Transmission  Company, a Delaware corporation, and  NRG Energy, Inc., a Delaware
corporation ("NRG"). NRG manages many of NSP's non-utility energy  subsidiaries.
The  principal executive office of NSP is, and after the Effective Time will be,
located at 414  Nicollet Mall,  Minneapolis, Minnesota  55401, telephone  number
(612)  330-5500. See "Selected Information Concerning WEC and NSP -- Business of
NSP" and "Primergy Following the Mergers -- Operations."

    NEW NSP.  New NSP is a Wisconsin corporation which was created to effect the
Reincorporation Merger.  It  has,  and  prior  to  the  Mergers  will  have,  no
operations except as contemplated by the Merger Agreement. The audited financial
statements  of New NSP are  attached as Annex N. NSP  is the only shareholder of
New NSP. Pursuant to the Merger Agreement, immediately prior to the consummation
of  the  NSP  Merger,  New  NSP   will  acquire  certain  utility  assets   from
NSP-Wisconsin.  Following the Mergers,  it is anticipated that  New NSP will not
retain ownership of the existing subsidiaries of NSP,

                                       10
<PAGE>
as it is expected that  NSP-Wisconsin will be merged  into WEPCO (which will  be
renamed  "Wisconsin Energy Company") and the  remaining subsidiaries of NSP will
be transferred to Primergy. The New NSP Articles will be amended, effective upon
the consummation of  the Mergers, to  change the  name of New  NSP to  "Northern
States  Power Company." The principal executive office  of New NSP is located at
414  Nicollet  Mall,  Minneapolis,  Minnesota  55401,  telephone  number   (612)
330-2903.  See "The Merger Agreement -- The Mergers" and "Primergy Following the
Mergers -- Operations."

    WEC SUB.  WEC Sub is a Wisconsin corporation which was created to effect the
NSP Merger. It has, and prior to the Mergers will have, no operations except  as
contemplated  by the Merger Agreement.  WEC is the only  shareholder of WEC Sub.
The principal  executive office  of WEC  Sub  is located  at 231  West  Michigan
Street,  P.O.  Box  2949,  Milwaukee, Wisconsin  53201,  telephone  number (414)
221-2345. See "The Merger Agreement -- The Mergers."

"Shareholder  Proposals"). Pursuant to the Merger Agreement, consummation of the
Mergers is conditioned upon approval of proposals (i), (ii) and (iii) above, but
is not conditioned upon approval by the shareholders of NSP of any other of  the
above proposals. NSP and WEC retain the right to waive the approval of either or
both of the Primergy Plans (proposals (ii) and (iii) above) as conditions to the
consummation of the Mergers. If approved, the Primergy Plans will be implemented
only  if the Mergers are  consummated. See "Meetings, Voting  and Proxies -- NSP
Meeting."

    The NSP  Meeting is  scheduled to  be held  at 10:00  a.m., local  time,  on

Stock entitled to notice of and to vote at the NSP Meeting.

    The NSP Board,  by a  unanimous vote, has  approved and  adopted the  Merger
Agreement  and the transactions  contemplated thereby, and  each of the Primergy
Plans, and recommends  that NSP  shareholders vote  FOR approval  of the  Merger
Agreement  and FOR approval of each of  the Primergy Plans. In addition, the NSP
Board recommends that NSP  shareholders vote FOR the  election of the  nominated
directors,  FOR ratification of the appointment of Price Waterhouse LLP as NSP's
independent accountants for 1995, and AGAINST the Shareholder Proposals.

    WEC.  At the WEC Meeting, the holders  of WEC Common Stock will be asked  to
consider  and vote upon  proposals (i) to  approve the Merger  Agreement and the
transactions contemplated thereby, including,  among other things, the  issuance
of  shares  of  Primergy  Common  Stock pursuant  to  the  terms  of  the Merger
Agreement, (ii) to approve the amendment to and restatement of the WEC  Articles
so  as to  change the name  of WEC  to "Primergy Corporation"  (the "Name Change
Amendment"), (iii)  to approve  the  amendment to  and  restatement of  the  WEC
Articles  so  as to  increase the  amount  of authorized  WEC Common  Stock from
325,000,000  shares  to  750,000,000  shares,  thereby  increasing  WEC's  total
authorized  capitalization from 340,000,000 shares  to 765,000,000 shares (which
includes the 15,000,000 shares of preferred stock, par value $.01 per share,  of
WEC  ("WEC Preferred Stock") currently authorized) (the "Common Stock Amendment"
and, together with the  Name Change Amendment,  the "WEC Articles  Amendments"),
(iv)  to  approve the  Primergy  Stock Incentive  Plan  and (v)  to  approve the
Primergy  Management  Incentive  Compensation  Plan.  Pursuant  to  the   Merger
Agreement,  consummation  of the  Mergers is  conditioned  upon approval  by the
shareholders of WEC of each of the proposals set forth above. NSP and WEC retain
the right to waive the

                                       11
<PAGE>
approval of either or both of the Primergy Plans (proposals (iv) and (v) above),
or the  approval  of the  Common  Stock  Amendment (proposal  (iii)  above),  as
conditions  to the  consummation of  the Mergers. If  approved, each  of the WEC
Articles Amendments will become effective, and  each of the Primergy Plans  will
be  implemented, only if the Mergers  are consummated. See "Meetings, Voting and
Proxies -- WEC Meeting."

    The WEC  Meeting is  scheduled  to be  held at  9:00  a.m., local  time,  on

THE MERGERS

    The Merger Agreement provides  for (a) the  Reincorporation Merger in  which
NSP  will be  merged with  and into  New NSP  with New  NSP to  be the surviving
corporation and (b) the NSP Merger in which WEC Sub will be merged with and into
New NSP with New  NSP to be  the surviving corporation.  Pursuant to the  Merger
Agreement, (i) each issued and outstanding share of NSP Common Stock (other than
shares  owned directly or  indirectly by NSP  or WEC and  NSP Dissenting Shares)
will be  cancelled and  ultimately converted  into the  right to  receive  1.626
shares  of Primergy Common Stock; (ii) each  issued and outstanding share of NSP
Preferred Stock (other than  shares owned directly or  indirectly by NSP or  WEC
and  NSP Dissenting Shares)  will be cancelled  and converted into  the right to
receive one share  of New  NSP Preferred  Stock with  terms (including  dividend
rates)  and designations under  the New NSP  Articles identical to  those of the
cancelled share of NSP  Preferred Stock under the  NSP Articles; and (iii)  each
issued  and outstanding share of WEC Common  Stock will be unchanged as a result
of the NSP Merger and will remain outstanding thereafter as a share of  Primergy
Common  Stock, so that the common shareholders  of WEC and NSP immediately prior
to the Mergers (except  for the holders  of NSP Dissenting  Shares) will all  be
common  shareholders  of  Primergy  immediately  upon  the  consummation  of the
Mergers.

    The Reincorporation Merger will  become effective at  the time specified  in
the  articles of merger  filed by New NSP  with the Secretaries  of State of the
States of Minnesota  and Wisconsin (the  "Reincorporation Effective Time").  The
NSP Merger will become effective at the time specified in the articles of merger
filed  by New  NSP with the  office of  the Secretary of  State of  the State of
Wisconsin. The "Effective Time" shall mean the time and date that the NSP Merger
becomes effective.

    See "The Merger Agreement -- The Mergers."

EXCHANGE OF STOCK CERTIFICATES

    As soon as  practicable after the  Effective Time, the  exchange agent  will
mail  transmittal instructions to each holder of  record of shares of NSP Common
Stock at  the  Effective  Time,  advising  such  holder  of  the  procedure  for
surrendering  such holder's certificates  ("NSP Certificates") which immediately
prior to the  Reincorporation Effective  Time represented shares  of NSP  Common
Stock  that were  cancelled and became  instead the right  ultimately to receive
shares of Primergy Common Stock for certificates representing shares of Primergy
Common Stock.  Holders  of  certificates  which  prior  to  the  Effective  Time
represented  shares of  NSP Common  Stock will  not be  entitled to  receive any
payment of dividends  or other distributions  on or payment  for any  fractional
share  with respect to their NSP  Certificates until such certificates have been
surrendered for certificates representing shares of Primergy Common Stock.  Cash
will be paid to NSP shareholders in lieu of fractional shares of Primergy Common
Stock.  Holders of  shares of  NSP Common  Stock should  not submit  their stock
certificates for exchange until a form of letter of transmittal and instructions
therefor are received. See "The Merger Agreement -- The Mergers."

    Holders of  NSP Preferred  Stock  do not  need  to exchange  their  existing
certificates   representing  shares  of  NSP   Preferred  Stock  for  new  stock
certificates. Each outstanding certificate representing shares of NSP  Preferred
Stock  immediately  prior  to  the  Effective Time  shall,  from  and  after the
Effective Time, represent the same number of shares of the corresponding  series
of   New  NSP  Preferred  Stock  with   terms  (including  dividend  rates)  and
designations under the  New NSP  Articles identical  to those  of the  cancelled
shares  of NSP Preferred Stock under the NSP Articles. After the Effective Time,
new certificates reflecting  the fact that  New NSP is  a Wisconsin  corporation
will be issued as outstanding stock certificates formerly representing shares of
NSP Preferred Stock are presented for transfer.

                                       13
<PAGE>
    Shareholders  of WEC need not exchange their existing stock certificates for
new stock certificates reflecting  WEC's name change  to Primergy. However,  any
WEC  shareholders desiring new stock certificates may, after the Effective Time,
submit their existing stock certificates representing shares of WEC Common Stock
to the transfer agent of Primergy  to obtain new certificates. Each  outstanding
certificate  representing shares  of WEC Common  Stock immediately  prior to the
Effective Time shall,  from and  after the  Effective Time,  represent the  same
number  of  shares  of Primergy  Common  Stock.  After the  Effective  Time, new
certificates bearing the  name of  Primergy will  be issued  as outstanding  WEC
stock certificates are presented for transfer.

PRIMERGY PLANS

    Pursuant  to the  Merger Agreement, Primergy  will adopt  the Primergy Stock
Incentive Plan  and  the  Primergy Management  Incentive  Compensation  Plan  to
replace  the comparable plans of NSP and  WEC. The Primergy Stock Incentive Plan
is a comprehensive  stock compensation  plan providing  for the  grant of  stock
options,  stock appreciation rights, restricted stock and performance units. The
Primergy Management  Incentive  Compensation  Plan  is  a  short-term  incentive
compensation  plan  providing  for cash  awards  based upon  the  achievement of
individual, group and  corporate performance goals  during periods of  up to  12
months.  For descriptions  of the Primergy  Plans, see "The  Mergers -- Primergy
Plans" and "Approval of Primergy Plans."

STOCK OPTION AGREEMENTS

    Pursuant to (i) the NSP Stock Option  Agreement dated as of April 28,  1995,
by  and between WEC and NSP (the "NSP  Stock Option Agreement") and (ii) the WEC
Stock Option Agreement dated as  of April 28, 1995, by  and between WEC and  NSP
(the "WEC Stock Option Agreement"; together with the NSP Stock Option Agreement,
the  "Stock Option  Agreements"), NSP  has granted  to WEC  the right  (the "WEC
Option"), and WEC has granted to NSP the right (the "NSP Option"; together  with
the  WEC Option, the "Options"), to purchase, under certain circumstances, up to
a certain number of  authorized but unissued shares  of the respective  issuer's
common  stock (representing 19.9% of the outstanding common stock of such issuer
on April 28, 1995), at a price of  $44.075 per share, in the case of NSP  Common
Stock,  and $27.675 per share, in the case  of WEC Common Stock. The exercise of
the Options is subject to certain conditions described in the Merger  Agreement.
See  "The  Stock Option  Agreements  -- General"  and  "The Merger  Agreement --
Termination Fees." In  addition, the  Stock Option Agreements  provide that  the
holder  of an Option has  the right to require  the issuer thereof to repurchase
from the holder of the Option (i) all  or any portion of the Option at any  time
the  Option  is exercisable  at  a price  which  is the  difference  between the
Market/Offer Price (as defined herein) and the exercise price of the Option, and
(ii) on or at any time  prior to April 30, 1997  (which date may be extended  to
October  31, 1997 under certain circumstances) all  or any portion of any shares
purchased pursuant to the  Option. See "The Stock  Option Agreements --  Certain
Repurchases."   The  Stock  Option  Agreements  are  intended  to  increase  the
likelihood that the Mergers will be consummated in accordance with the terms  of
the  Merger Agreement and may have  the effect of discouraging competing offers.
See "The Stock Option Agreements."

    Further, the Stock Option Agreements contemplate the continuation of certain
standstill provisions and provide that any shares of the other party acquired or
otherwise beneficially owned must be voted for and against each matter submitted
to a shareholder vote in  the same proportion as  the other shareholders of  the
issuer  thereof vote for and  against such matter. See  "The Merger Agreement --
Standstill Provisions" and "The Stock Option Agreements -- Voting."

TREATMENT OF SHARES; RATIO

    Each share of NSP Common Stock  issued and outstanding immediately prior  to
the  Reincorporation  Effective Time  (other than  NSP Dissenting  Shares) will,
pursuant to the Merger Agreement, be  cancelled and converted into the right  to
receive  one share of New NSP Common Stock which, in turn, will be cancelled and
converted into the right to receive 1.626 shares of Primergy Common Stock.  Each
share  of WEC Common  Stock outstanding immediately prior  to the Effective Time
will, upon consummation of the Mergers, remain outstanding and unchanged as  one
share of Primergy Common

                                       14
<PAGE>
Stock.  Holders of  NSP Common  Stock will  receive cash  in lieu  of fractional
shares of Primergy Common Stock. Each  share of NSP Preferred Stock  outstanding
immediately  prior  to  the  Reincorporation  Effective  Time  (other  than  NSP
Dissenting Shares)  will, upon  consummation of  the Mergers,  be cancelled  and
converted  into the right to  receive one share of  New NSP Preferred Stock with
terms (including dividend  rates) and  designations under the  New NSP  Articles
identical  to those of the cancelled share  of NSP Preferred Stock under the NSP
Articles. Each share of common stock, par value $.01 per share, of WEC Sub ("WEC
Sub Common Stock")  issued and  outstanding immediately prior  to the  Effective
Time will, upon consummation of the Mergers, be cancelled and converted into one
share of New NSP Common Stock. See "The Merger Agreement -- The Mergers."

BACKGROUND

    For  a description  of the  background of the  Mergers, see  "The Mergers --
Background of the Mergers."

REASONS FOR THE MERGERS

    NSP and  WEC  believe  that  the Mergers  offer  significant  strategic  and
financial benefits to each company and to their respective shareholders, as well
as  to  their employees  and  customers and  the  communities in  which  they do
business. These benefits include, among others:

    - Maintenance of competitive  rates that  will improve ability  to meet  the
      challenges  of  the increasingly  competitive  environment in  the utility
      industry.

    - Integration of  corporate  and  administrative  functions,  including  the
      elimination  of  duplicate  positions, limiting  capital  expenditures for
      administrative facilities and  information systems, and  savings in  areas
      such as legal, audit, and consulting fees.

    - Expanded  management  resources and  ability to  select leadership  from a
      larger and more diverse management pool.

    - Centralized management, supervision, and  operation of nuclear  generating
      facilities.

    - Greater  purchasing  power  for  items  such  as  fuel  and transportation
      services, and streamlining of inventories.

    - More efficient pursuit of diversification into non-utility areas.

    - Increased geographic diversity of  service territories, reducing  exposure
      to local changes in economic, competitive, or climatic conditions.

    - Continued  ability  to  play a  strong  role in  the  economic development
      efforts of the communities NSP and WEC's utility subsidiaries now serve.

    - Cost savings  in a  variety  of categories,  estimated  to result  in  net
      savings  of approximately $2 billion over  a ten-year period following the
      Mergers.

    See "The Mergers -- Reasons for  the Mergers; Recommendations of the  Boards
of Directors."

OPINIONS OF FINANCIAL ADVISORS

    NSP.  On April  28, 1995, Goldman, Sachs  & Co. ("Goldman Sachs")  delivered
its  oral opinion to the NSP Board that,  as of that date, the Ratio pursuant to
the Merger Agreement  is fair  to the  holders of  shares of  NSP Common  Stock.
Goldman Sachs subsequently confirmed its April 28, 1995 oral opinion by delivery
of   its  written   opinion  dated   as  of  the   date  of   this  Joint  Proxy
Statement/Prospectus. The full  text of  the written opinion  of Goldman  Sachs,
dated  as of the date of this Joint Proxy Statement/Prospectus, which sets forth
assumptions made,  matters considered  and limits  of the  review undertaken  in
connection  with the opinion, is attached hereto  as Annex F and is incorporated
herein by reference. HOLDERS  OF SHARES OF  NSP COMMON STOCK  ARE URGED TO,  AND
SHOULD,  READ SUCH  OPINION IN  ITS ENTIRETY.  See "The  Mergers --  Opinions of
Financial Advisors" and Annex F.

    WEC.  Barr Devlin  & Co. Incorporated ("Barr  Devlin") delivered to the  WEC
Board its written opinions dated April 28, 1995 and the date of this Joint Proxy
Statement/Prospectus  stating that, as  of the dates of  such opinions and based
upon  the  assumptions  made,  matters  considered  and  limits  of  the  review
undertaken,  as set forth in such opinions,  the Ratio is fair, from a financial
point of view, to the  holders of the WEC Common  Stock. The written opinion  of
Barr  Devlin dated the date of this Joint Proxy Statement/Prospectus is attached
hereto as Annex G and is incorporated herein by reference. HOLDERS OF SHARES  OF
WEC  COMMON STOCK ARE URGED  TO, AND SHOULD, READ  SUCH OPINION IN ITS ENTIRETY.
The April 28, 1995  opinion is substantially identical  to the opinion  attached
hereto. See "The Mergers -- Opinions of Financial Advisors" and Annex G.

INTERESTS OF CERTAIN PERSONS IN THE MERGERS

    DIRECTORSHIPS.  The Merger Agreement provides that the Board of Directors of
Primergy  (the "Primergy Board") will, upon consummation of the Mergers, consist
of 12 persons  with six persons  designated by NSP,  including James J.  Howard,
Chairman  of the Board,  President and Chief  Executive Officer of  NSP, and six
persons designated by WEC,  including Richard A. Abdoo,  Chairman of the  Board,
President  and Chief Executive Officer of WEC.  See "The Mergers -- Interests of
Certain Persons in the Mergers -- Board of Directors."

    EMPLOYMENT AGREEMENTS.  Each of Messrs. Howard and Abdoo will enter into  an
employment  agreement with Primergy to become effective upon consummation of the
Mergers (the "Employment  Agreements"). Pursuant to  the Employment  Agreements,
Mr.  Howard will serve as Chairman and  Chief Executive Officer of Primergy from
and after the Effective Time until the  later of the date of the annual  meeting
of  the shareholders  of Primergy that  occurs in 1998  and the last  day of the
sixteenth full month following the Effective Time, and thereafter will retire as
Chief Executive Officer but will continue  to serve as Chairman until the  later
of July 1, 2000, or two years after he ceases to be Chief Executive Officer. Mr.
Abdoo  will serve  as Vice  Chairman, President  and Chief  Operating Officer of
Primergy from and after the Effective Time  until Mr. Howard ceases to be  Chief
Executive  Officer, and  thereafter will serve  as Vice  Chairman, President and
Chief Executive Officer. Mr. Abdoo will assume the position of Chairman when Mr.
Howard ceases to be Chairman. See  "The Mergers -- Interests of Certain  Persons
in the Mergers -- Employment Agreements."

    SEVERANCE  POLICIES.  Effective April 28, 1995,  the NSP and WEC Boards have
each adopted  a Senior  Executive Severance  Policy (the  "Severance  Policies")
providing  for  severance  benefits  to the  respective  NSP  and  WEC employees
designated as participants (the "Participants"). The Severance

                                       16
<PAGE>
Policies will be binding upon Primergy. A total of 25 NSP executives and 25  WEC
executives  have been designated as  Participants under the respective Severance
Policies. The  Severance Policies  provide  severance benefits  to  Participants
whose  employment is terminated  under certain circumstances  at any time before
(i)  the  second  anniversary  of  the  Effective  Time  (if  the  Mergers   are
consummated) or (ii) April 28, 2000 (if the Mergers are not consummated), unless
further  extended by the respective Boards  of Directors. If all Participants in
the  Severance  Policies  had  been  terminated   as  of  July  1,  1996   under
circumstances giving rise to an entitlement to severance benefits, the aggregate
value of the severance benefits (assuming specified increases in base salary and
specified   incentive  compensation   levels)  would   have  been  approximately
$19,000,000 for the NSP Participants  and approximately $13,000,000 for the  WEC
Participants. See "The Mergers -- Employee Plans and Severance Arrangements."

    EMPLOYEE  PLANS.  Under  certain benefit plans  and agreements maintained or
entered into by WEC, certain directors, officers and other employees of WEC will
be entitled to immediate vesting of stock options and vesting and/or payment  of
certain  retirement  and other  deferred compensation  upon consummation  of the
Mergers. WEC has agreed to use its best efforts to obtain all necessary consents
to the  waiver of  these entitlements  with  respect to  the Mergers.  See  "The
Mergers  -- Interests of  Certain Persons in  the Mergers --  Employee Plans and
Severance Arrangements."

    INDEMNIFICATION.   The parties  have  agreed in  the Merger  Agreement  that
Primergy  will indemnify, to the fullest extent permitted by applicable law, the
present and former officers, directors and  employees of each of the parties  to
the  Merger Agreement or  any of their  subsidiaries against certain liabilities
(i) arising out of actions or omissions  occurring at or prior to the  Effective
Time  that arise from  or are based on  such service as  an officer, director or
employee or  (ii)  that  are  based  on  or arise  out  of  or  pertain  to  the
transactions  contemplated by the Merger Agreement,  and to maintain policies of
directors' and officers' liability insurance for  a period of not less than  six
years after the Effective Time. To the fullest extent permitted by law, from and
after the Effective Time, all rights to indemnification existing in favor of the
employees,  agents,  directors  or officers  of  NSP, WEC  and  their respective
subsidiaries with respect  to their activities  as such prior  to the  Effective
Time,  as provided in their respective  articles of incorporation and bylaws, in
effect on  April 28,  1995, or  otherwise in  effect on  April 28,  1995,  shall
survive  the Mergers and shall continue in full force and effect for a period of
not less than six years from the  Effective Time. See "The Mergers --  Interests
of  Certain Persons in the Mergers -- Indemnification" and "The Merger Agreement
-- Indemnification."

MANAGEMENT OF PRIMERGY

    As provided in  the Merger Agreement,  at the Effective  Time, the  Primergy
Board  will consist of 12 directors, six designated by WEC and six designated by
NSP. At the Effective Time, Mr. Howard will become Chairman and Chief  Executive
Officer  of Primergy,  and Mr.  Abdoo will  become Vice  Chairman, President and
Chief Operating Officer of  Primergy. To date, NSP  and WEC have not  determined
which  individuals, in addition to Messrs.  Howard and Abdoo, will be designated
to serve as directors or officers of Primergy as of the Effective Time. See "The
Mergers --  Employment  Agreements"  and  "Primergy  Following  the  Mergers  --
Management of Primergy."

    The  obligations of  NSP, on the  one hand, and  WEC, on the  other hand, to

material third-party consents,  the receipt  of letters from  affiliates of  the

constituting more than 5% of the number of issued and outstanding shares of  NSP
Common Stock and NSP Preferred Stock, taken together as a single class. See "The
Merger  Agreement  --  Conditions  to  Each  Party's  Obligation  to  Effect the
Mergers."

RIGHTS TO TERMINATE, AMEND OR WAIVE CONDITIONS

    The  Merger  Agreement  may  be  terminated  under  certain   circumstances,
including: by mutual consent of WEC and NSP; by any party if the Mergers are not
consummated  by April 30, 1997  (which date may be  extended to October 31, 1997
under  certain  circumstances);  by  any  party  if  the  requisite  shareholder
approvals  are  not obtained  or  if any  state or  federal  law or  court order
prohibits consummation of the Mergers; by a non-breaching party if there  occurs

-- Certain Repurchases."

    The  Merger  Agreement may  be amended  by  the Boards  of Directors  of the
parties at any time before or after its approval by the shareholders of NSP  and
WEC,  but after  any such  approval, no  amendment may  be made  which alters or
changes (i) the amount or kind of shares, rights or the manner of conversion  of
such  shares, (ii)  the terms  or conditions  of the  Merger Agreement,  if such
alteration or  change, alone  or in  the aggregate,  would materially  adversely
affect the rights of the WEC shareholders or NSP shareholders, or (iii) any term
of  the form  of the  Primergy Articles (as  defined herein)  attached hereto as
Annex H, except for  alterations or changes that  could otherwise be adopted  by
the WEC Board without the further approval of such shareholders. See "The Merger
Agreement -- Amendment and Waiver."

    At  any  time  prior to  the  Effective  Time, to  the  extent  permitted by
applicable law, the conditions to NSP's  or WEC's obligations to consummate  the
Mergers may be waived by the other party. Any determination to waive a condition
would  depend upon  the facts  and circumstances  existing at  the time  of such
waiver and would be made by  the waiving party's Board of Directors,  exercising
its  fiduciary  duties  to such  party  and  its shareholders.  See  "The Merger
Agreement -- Amendment and Waiver."

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

    Each party's obligation  to effect  the Mergers  is conditioned  on (i)  the
receipt  of a  private letter ruling  from the IRS  providing certain assurances
regarding the  federal income  tax  consequences of  the  Mergers and  (ii)  the
delivery  of an opinion to NSP from  Wachtell, Lipton, Rosen & Katz, counsel for
NSP, and an opinion to WEC from Skadden, Arps, Slate, Meagher & Flom or  Quarles
&  Brady, counsel for WEC, each dated as of the Closing Date, based upon certain
customary representations

                                       18
<PAGE>
and  assumptions  set  forth  therein   and  on  such  private  letter   ruling,
substantially  to the effect that, for federal  income tax purposes, each of the
Mergers constitutes  a tax-free  reorganization within  the meaning  of  Section
368(a) of the Internal Revenue Code of 1986, as amended (the "Code").

    Provided  that such a ruling is obtained (in which case, provided that there
shall have been no adverse changes in applicable law or facts at such time, such
opinions of counsel will be delivered), in general: (i) no gain or loss will  be
recognized by NSP, New NSP, WEC or WEC Sub pursuant to the Mergers; (ii) no gain
or  loss will  be recognized by  holders of  NSP Preferred Stock  and NSP Common
Stock upon the cancellation  of their NSP Preferred  Stock and NSP Common  Stock
and  conversion thereof into New  NSP Preferred Stock and  New NSP Common Stock,
respectively, pursuant to the Reincorporation Merger; (iii) no gain or loss will
be recognized by holders of New NSP Common Stock upon the cancellation of  their
New  NSP Common Stock and conversion thereof into Primergy Common Stock pursuant
to the NSP Merger; and (iv) no  gain or loss will be recognized by  shareholders
of  WEC upon the Reincorporation  Merger or the NSP  Merger. See "The Mergers --
Certain Federal Income Tax Consequences."

    EACH SHAREHOLDER SHOULD CONSULT  HIS OR HER  OWN TAX ADVISOR  AS TO THE  TAX
CONSEQUENCES  OF THE MERGERS TO SUCH  SHAREHOLDER UNDER FEDERAL, STATE, LOCAL OR
ANY OTHER APPLICABLE LAW.

OPERATIONS AFTER THE MERGERS

    Following the Mergers, Primergy will be a registered public utility  holding
company  under the 1935 Act, and New NSP (which will be renamed "Northern States
Power Company") and  WEPCO (which  will be renamed  "Wisconsin Energy  Company")
will operate as its principal subsidiaries. The headquarters of Primergy will be
in Minneapolis, Minnesota. The headquarters of the two utility subsidiaries will
remain   in  their  current  locations,   Northern  States  Power  Company's  in
Minneapolis and  Wisconsin Energy  Company's  in Milwaukee.  Primergy's  utility
subsidiaries  will serve approximately 2,300,000  electric customers and 750,000
natural gas customers in portions  of Minnesota, Wisconsin, North Dakota,  South
Dakota  and the Upper Peninsula of Michigan. The business of Primergy will be to
operate  as  a  holding  company  for  its  utility  subsidiaries,  and  various
non-utility  subsidiaries.  It is  anticipated  that Wisconsin  Natural  will be
merged  into  WEPCO  by  January  1,  1996,  as  previously  planned,  and  that
NSP-Wisconsin  will  merge into  WEPCO following  the  Mergers. Pursuant  to the
Merger  Agreement,   New  NSP   will  acquire   certain  utility   assets   from
NSP-Wisconsin.  NSP and WEC recognize that a  divestiture mandated by the SEC of
their  existing  gas  operations  and   certain  non-utility  operations  is   a
possibility  under the registered holding company  structure, but intend to seek
approval from the SEC to maintain such businesses. See "Regulatory Matters"  and
"Primergy Following the Mergers -- Operations."

    Pursuant  to  the  Merger  Agreement,  Primergy  and  its  subsidiaries will
continue to  play a  strong role  in  the economic  development efforts  of  the
communities  NSP and  WEC now  serve. The  philanthropic and  volunteer programs
currently maintained  by the  two  companies will  be continued.  See  "Primergy
Following the Mergers -- Operations."

NSP PREFERRED STOCK

    Pursuant  to the Merger Agreement, NSP will  be merged into New NSP and each
issued and outstanding  share of NSP  Preferred Stock (other  than shares  owned
directly  or  indirectly  by NSP  or  WEC  and NSP  Dissenting  Shares)  will be
cancelled and converted into the right to receive one share of New NSP Preferred
Stock with terms (including dividend rates)  and designations under the New  NSP
Articles identical to those of the cancelled shares of NSP Preferred Stock under
the  NSP  Articles.  Currently,  earnings  from  NSP's  subsidiaries  (including
NSP-Wisconsin) are available as a source  for dividends on NSP Preferred  Stock.
It is anticipated that, following the Mergers, NSP-Wisconsin will be merged into
WEPCO  (which will be renamed "Wisconsin Energy Company") and all of NSP's other
subsidiaries will be  transferred to  Primergy. When and  if these  transactions
occur,  the  earnings  of the  current  subsidiaries  of NSP  will  cease  to be
available as a  source of dividends  on New  NSP Preferred Stock.  NSP does  not
believe  that these transfers will impair New  NSP's ability to pay dividends on
the

                                       19
<PAGE>
New NSP  Preferred Stock  during the  foreseeable future.  New NSP's  operations
would  continue  to include  the existing  electric  and gas  utility operations
conducted directly by NSP. Also,  as indicated below under "Selected  Historical
and  Pro Forma Data,"  NSP's ratio of  earnings to fixed  charges plus preferred
dividend requirements was 3.3 for the twelve months ended June 30, 1995, and New
NSP's pro  forma ratio  of earnings  to fixed  charges plus  preferred  dividend
requirements  for the twelve  months ended June  30, 1995 was  3.1, after giving
effect to the Mergers, the anticipated merger of NSP-Wisconsin into WEPCO (which
will be  renamed "Wisconsin  Energy Company")  and the  anticipated transfer  of
NSP's remaining subsidiaries to Primergy. See "Primergy Following the Mergers --
Operations."

REGULATORY MATTERS

    The  approval  of  the  SEC  under  the  1935  Act,  the  Nuclear Regulatory
Commission (the "NRC")  under the  Atomic Energy Act  of 1954,  as amended  (the
"Atomic  Energy  Act"), the  Federal Energy  Regulatory Commission  (the "FERC")
under the  Federal  Power  Act,  as  well as  the  approval  of  the  Minnesota,
Wisconsin,  North Dakota and Michigan utility commissions under applicable state
laws and the expiration  or termination of the  applicable waiting period  under
the  Hart-Scott-Rodino Antitrust Improvements Act of  1976, as amended (the "HSR
Act"), are  required  in  order  to consummate  the  Mergers.  In  addition,  an
application  for disclaimer of jurisdiction has been filed with the South Dakota
utilities commission.

    Upon consummation  of  the Mergers,  Primergy  must register  as  a  holding
company  under the 1935 Act. The 1935 Act imposes restrictions on the operations
of registered  holding  company  systems.  Among  these  are  requirements  that
securities  issuances, sales and acquisitions of utility assets or of securities
of utilities companies and  acquisitions of interests in  any other business  be
approved  by the SEC. The 1935 Act also limits the ability of registered holding
companies to engage in non-utility ventures and regulates holding company system
service companies and the rendering of services by holding company affiliates to
the system's utilities.

    The SEC may require as a condition  to its approval of the Mergers that  NSP
and  WEC divest  their gas utility  properties and  possibly certain non-utility
ventures within a reasonable time after the Mergers. In a few cases, the SEC has
allowed the retention of such properties or deferred the question of divestiture
for a substantial period of time. In those cases in which divestiture has  taken
place, the SEC has usually allowed enough time to complete the divestiture so as
to  allow the applicant to  avoid a "fire sale" of  the divested assets. NSP and
WEC believe strong policy  reasons and prior SEC  decisions exist which  support
their  retaining their existing gas utility properties and non-utility ventures,
or, alternatively, which  support deferring  the question of  divestiture for  a
substantial  period of time. Accordingly, WEC and NSP will request in their 1935
Act application that NSP  and WEC be  allowed to retain,  or in the  alternative
that  the question of divestiture  be deferred with respect  to, NSP's and WEC's
existing gas utility properties and non-utility ventures.

    Following consummation  of the  Mergers, Primergy  also will  be subject  to
regulation  by  the  Public  Service  Commission  of  Wisconsin  (the "Wisconsin
Commission") under Section 196.795, Wis. Stats. (the "Wisconsin Holding  Company
Act")  as WEC  is currently.  The Wisconsin  Holding Company  Act will regulate,
among  other  things,  the  type  and  amount  of  investments  in   non-utility
businesses.

    Under  the Merger Agreement, NSP  and WEC have agreed  to use all reasonable
efforts to  obtain all  governmental authorizations  necessary or  advisable  to
consummate  or  effect the  transactions contemplated  by the  Merger Agreement.
Various parties may seek intervention in these proceedings to oppose the Mergers
or to have conditions imposed upon the receipt of necessary approvals. While WEC
and NSP believe that  they will receive the  requisite regulatory approvals  for
the Mergers, there can be no assurance as to the timing of such approvals or the
ability  of  such parties  to  obtain such  approvals  on satisfactory  terms or
otherwise. It  is a  condition to  the consummation  of the  Mergers that  final
orders  approving the  Mergers be  obtained from  the various  federal and state
commissions described above  on terms and  conditions which would  not have,  or
would  not  be reasonably  likely  to have,  a  material adverse  effect  on the
business,  assets,   financial   condition   or   results   of   operations   of

                                       20
<PAGE>
Primergy  and its  prospective subsidiaries taken  as a whole,  or on Primergy's
prospective utility subsidiaries located  in the State of  Minnesota taken as  a
whole,  or  on its  prospective  utility subsidiaries  located  in the  State of
Wisconsin taken as a whole, or  which would be materially inconsistent with  the
agreements  of the parties  contained in the  Merger Agreement. There  can be no
assurance that any  such approvals  will not  contain terms  or conditions  that
cause  such approvals to fail  to satisfy such condition  to the consummation of
the Mergers. See "Regulatory Matters."

ACCOUNTING TREATMENT

    NSP and  WEC believe  that  the Mergers  will be  treated  as a  pooling  of
interests  for accounting purposes.  See "The Mergers  -- Accounting Treatment."
The receipt by each of WEC and NSP of a letter from their respective independent
accountants,  stating  that  the  transaction  will  qualify  as  a  pooling  of
interests,  is a  condition precedent to  consummation of the  Mergers. See "The
Merger Agreement  --  Conditions  to  Each  Party's  Obligation  to  Effect  the
Mergers."

DISSENTERS' RIGHTS

    Under Minnesota law, holders of record of NSP Common Stock and NSP Preferred
Stock  as of the  NSP Record Date who  do not wish to  accept shares of Primergy
Common Stock in the NSP Merger or New NSP Preferred Stock in the Reincorporation
Merger, as the case may be, have the  right to have the fair value of their  NSP
shares appraised by judicial determination and paid to them in cash. In order to
perfect  such dissenters' rights, holders of  NSP Common Stock and NSP Preferred
Stock must  comply with  the  procedural requirements  of the  MBCA,  including,
without  limitation, filing written notice with NSP  prior to the NSP Meeting of
such shareholder's intention to dissent and demand payment of the fair value  of
his  or her  shares, not voting  in favor of  the Merger Agreement  and making a
written demand for  payment and  depositing the  certificates representing  such
shares within 30 days after notice is given by NSP of the results of the vote at
the NSP Meeting. See "The Mergers -- Minnesota Dissenters' Rights" and Annex M.

    Under  Wisconsin law,  the holders of  WEC Common Stock  have no dissenters'
rights. See "The Mergers -- No Wisconsin Dissenters' Rights."

DIVIDENDS

    WEC AND NSP.  Pursuant  to the Merger Agreement, each  of WEC and NSP  shall
not,  and shall not permit any of its direct subsidiaries to, declare or pay any
dividends on, or  make other  distributions in respect  of, any  of its  capital
stock,  other than to such party or its wholly-owned subsidiaries and other than
dividends required to be paid on any series of NSP Preferred Stock in accordance
with the terms thereof, dividends required to be paid on any shares of preferred
stock of WEPCO ("WEPCO Preferred Stock")  in accordance with the terms  thereof,
and  regular quarterly dividends to  be paid on NSP  Common Stock and WEC Common
Stock not to exceed 106% of the dividends for the prior fiscal year.

    PRIMERGY.  It  is anticipated that  Primergy will adopt  NSP's common  share
dividend  payment level  as of  the Effective Time  adjusted for  the Ratio. NSP
currently pays  $2.70 per  share annually,  and WEC's  annual dividend  rate  is
currently  $1.47 per share. Based on the  Ratio and NSP's current dividend rate,
the pro forma dividend rate for Primergy would be $1.66 per share. The  dividend
policy  of Primergy is subject  to evaluation from time  to time by the Primergy
Board based on  Primergy's results of  operations, financial condition,  capital
requirements   and   other   relevant   considerations,   including   regulatory
considerations.  See  "Primergy  Following  the  Mergers"  and  "Description  of
Primergy Capital Stock -- Primergy Common Stock."

AMENDMENTS TO WEC ARTICLES

    Pursuant to the Merger Agreement, subject to the approval of each of the WEC
Articles  Amendments by WEC's shareholders at  the WEC Meeting, the WEC Articles
will be amended and restated  no later than the Effective  Time in the form  set
forth  in Annex H. The WEC Articles Amendments  would (i) change the name of WEC
to Primergy Corporation and  (ii) increase the amount  of authorized WEC  Common
Stock  from 325,000,000 shares  to 750,000,000 shares,  thereby increasing WEC's
authorized

                                       21
<PAGE>
capitalization from 340,000,000 shares to 765,000,000 shares (which includes the
15,000,000  shares  of  WEC  Preferred  Stock  presently  authorized).  The  WEC
Articles,  as  so  amended  and  restated,  will  be  the  Restated  Articles of
Incorporation of Primergy (the  "Primergy Articles") at  the Effective Time  and
until  thereafter amended in accordance with the WBCL and the Primergy Articles.
See "Amendments to and Restatement of WEC Restated Articles of Incorporation."

COMPARISON OF RIGHTS OF NSP SHAREHOLDERS

    As a result  of the Mergers,  holders of  NSP Common Stock  (other than  NSP
Dissenting   Shares)  will   become  shareholders   of  Primergy,   a  Wisconsin
corporation. Such shareholders  will have certain  different rights as  Primergy
shareholders  than  they  had  as  shareholders  of  NSP,  both  because  of the
differences between the NSP Articles and  the Primergy Articles, and because  of
differences  between  Wisconsin and  Minnesota corporation  law. Holders  of NSP
Preferred  Stock  (other  than  NSP  Dissenting  Shares)  will  receive  in  the
Reincorporation  Merger  shares  of  preferred stock  of  New  NSP,  a Wisconsin
corporation. Although the terms (including  dividend rates) and designations  of
the shares of New NSP Preferred Stock (as set forth in the New NSP Articles, the
form  of which is attached hereto as Annex  J) will be identical to those of the
corresponding shares of NSP Preferred Stock (as set forth in the NSP  Articles),
the  rights of holders of  New NSP Preferred Stock  will be different in certain
respects under Wisconsin law than the  rights of holders of NSP Preferred  Stock
under  Minnesota law due to differences between Minnesota and Wisconsin law. For
a comparison  of  Wisconsin  and  Minnesota  law  and  the  articles  and  bylaw
provisions of NSP and Primergy, see "Comparison of Shareholder Rights."

SELECTED UNAUDITED PRO FORMA FINANCIAL DATA

    The following selected  unaudited pro forma  financial information  combines
the  historical consolidated balance sheets and  statements of income of NSP and
WEC, including  their  respective  subsidiaries,  after  giving  effect  to  the
Mergers.  The unaudited pro forma combined  condensed balance sheet data at June
30, 1995 and December 31, 1994, 1993 and  1992 give effect to the Mergers as  if
they had occurred at the respective balance sheet dates. The unaudited pro forma
combined  condensed statements of income for each of the years in the three-year
period ended December  31, 1994, and  the 12-month period  ended June 30,  1995,
give  effect to the  Mergers as if they  had occurred at  January 1, 1992. These
statements are prepared on the basis of accounting for the Mergers as a  pooling
of  interests and are based  on the assumptions set  forth in the notes thereto.
The following  information  is  not  necessarily  indicative  of  the  financial
position  or operating  results that  would have  occurred had  the Mergers been
consummated on the  date as of  which, or at  the beginning of  the periods  for
which,  the Mergers are being  given effect nor is  it necessarily indicative of
future operating  results  or  financial  position.  See  "Unaudited  Pro  Forma
Combined Condensed Financial Information."

NOTES TO SELECTED HISTORICAL AND PRO FORMA DATA
(a)  Income/earnings   based  on   income  from   continuing  operations  before
     accounting changes and after preferred dividend requirements.
(b)  For purposes  of  computing  the  ratios  of  earnings  to  fixed  charges,
     "earnings"  consist of income from  continuing operations before accounting
     changes, plus  interest charges,  preferred dividend  requirements,  income
     taxes,   and  the  estimated  interest  component  of  rentals,  minus  the
     undistributed equity in  earnings of  unconsolidated investees.  "Earnings"
     also   include  allowance  for   borrowed  and  other   funds  used  during
     construction. "Fixed charges"  consist of interest  charges, the  estimated
     interest  component  of rentals  and the  pre-tax dividend  requirements on
     subsidiary preferred  stock.  Currently, the  NSP  Preferred Stock  is  not
     issued  by a subsidiary;  subsequent to the Mergers,  the New NSP Preferred
     Stock will be issued by a subsidiary  of Primergy. The pro forma ratios  of
     earnings  to fixed charges plus preferred  dividend requirements of New NSP
     for the years ended  December 31, 1992,  1993 and 1994  and for the  twelve
     months ended June 30, 1995 are 2.5x, 3.2x, 3.5x and 3.1x, respectively.
(c)  Includes  bank  and other  notes payable,  commercial paper  borrowings and
     current portion of long-term debt.
(d)  Income/earnings for  the fiscal  year ended  December 31,  1994 includes  a
     pre-tax  charge of $73.9  million for WEC  revitalization costs recorded in
     the first quarter of 1994.

(e)  Pro forma per common  share amounts give effect  to the conversion of  each
     share  of NSP Common Stock outstanding into 1.626 shares of Primergy Common
     Stock. See "The Merger  Agreement -- The  Mergers" and "Primergy  Following
     the  Mergers  -- Dividends."  Pro forma  per common  share amounts  do not,
     however, give effect  to the  synergies of the  transaction or  transaction
     costs.  For a description of the synergies, see "The Mergers -- Reasons for
     the Mergers; Recommendations of the Boards of Directors."
(f)  Represents the  pro forma  equivalent  of one  share  of NSP  Common  Stock
     calculated by multiplying the pro forma information by the conversion ratio
     of  1.626 shares  of Primergy  Common Stock  for each  share of  NSP Common
     Stock.
(g)  Pursuant to SEC requirements, calculated based on historical dividends paid
     by NSP and WEC combined. It  is anticipated that Primergy will adopt  NSP's
     common  share  dividend  payment level  adjusted  for the  Ratio,  and that
     therefore the holders of  shares of NSP Common  Stock immediately prior  to
     the  Mergers  will be  entitled  to an  annual  dividend on  the  shares of
     Primergy Common Stock that  they receive equal in  amount to the  dividends
     they would have received in respect of their shares of NSP Common Stock.

    On April 28, 1995, the last full trading day before the public  announcement
of the execution and delivery of the Merger Agreement, the high, low and closing
sales  prices per share of (i) NSP Common  Stock on the NYSE Composite Tape were
$44.25, $ 43.875 and $44.25, respectively, and (ii) WEC Common Stock on the NYSE
Composite Tape were $27.75, $27.50 and $27.75, respectively.

    On August 4,  1995, the most  recent date  for which it  was practicable  to
obtain    market   price   data    prior   to   printing    this   Joint   Proxy
Statement/Prospectus, the high, low  and closing sales prices  per share of  NSP
Common  Stock  on the  NYSE Composite  Tape were  $44.375, $43.875  and $43.875,
respectively, and the high, low and closing sales prices per share of WEC Common
Stock  on  the  NYSE   Composite  Tape  were   $27.375,  $27.125  and   $27.125,
respectively.  Accordingly, if  the Mergers had  been consummated  on that date,
each share of  NSP Common  Stock would  have been  converted into  the right  to
receive  1.626 shares of Primergy Common Stock  having a market value of $44.105
based upon the closing price per share of WEC Common Stock on such date.

    The market prices of NSP  Common Stock and WEC  Common Stock are subject  to
fluctuation.  NSP shareholders and WEC shareholders  are urged to obtain current
market quotations for NSP Common Stock and WEC Common Stock.

NSP MEETING

    PURPOSE  OF NSP MEETING.  The purpose of  the NSP Meeting is to consider and
vote upon: (i) a proposal to  approve the Merger Agreement and the  transactions
contemplated  thereby, (ii) a  proposal to approve  the Primergy Stock Incentive
Plan, (iii) a proposal to approve the Primergy Management Incentive Compensation
Plan, (iv) a proposal to elect four directors to Class III to serve for terms of

authorizes  the voting of shares  represented by the proxy  on all other matters
that  may  properly  come  before  the  NSP  Meeting,  and  any  adjournment  or
postponement  thereof, and it is the intention of the proxy holders to take such
action in  connection  therewith as  shall  be  in accordance  with  their  best
judgment.

    The  NSP  Board, by  a unanimous  vote, has  approved the  Merger Agreement,
authorized the execution and delivery of the Merger Agreement, and approved  the
Primergy  Plans,  and recommends  that NSP  shareholders  vote FOR  approval and
adoption of  the  Merger Agreement,  FOR  the  approval of  the  Primergy  Stock
Incentive   Plan,  FOR  the  approval   of  the  Primergy  Management  Incentive
Compensation Plan, FOR the election of the nominated directors, FOR ratification
of the appointment of Price Waterhouse LLP as NSP's independent accountants  for
1995 and AGAINST the Shareholder Proposals.

    Pursuant to the Merger Agreement, consummation of the Mergers is conditioned
upon  approval of proposals  (i), (ii) and  (iii) above, but  is not conditioned
upon approval by the shareholders  of NSP of any  other of the above  proposals.
NSP  and WEC retain  the right to  waive the approval  of either or  both of the
Primergy  Plans  (proposals  (ii)  and   (iii)  above)  as  conditions  to   the
consummation of the Mergers. If approved, the Primergy Plans will be implemented
only if the Mergers are consummated.

    DATE,  PLACE AND TIME; RECORD DATE.  The NSP Meeting is scheduled to be held
on Wednesday, September 13, 1995, at 10:00 a.m., local time, at the  Minneapolis
Convention  Center,  1301  South Second  Avenue,  Minneapolis,  Minnesota 55463,
Exhibit Hall  I.  Holders of  record  of shares  of  NSP Common  Stock  and  NSP
Preferred  Stock at the close of business on July 27, 1995, the NSP Record Date,
will be entitled to notice of  and to vote at the  NSP Meeting. At the close  of
business  on the  NSP Record  Date, 67,693,931  shares of  NSP Common  Stock and
2,400,000 shares of NSP Preferred Stock (of which 275,000 shares are of a series
which is entitled  to three  votes per share)  were issued  and outstanding  and
entitled to vote.

    VOTING  RIGHTS.  Each outstanding  share of NSP Common  Stock is entitled to
one vote and each outstanding  share of NSP Preferred  Stock is entitled to  one
vote  (other  than  NSP Preferred  Stock  of the  series  designated "Cumulative
Preferred Stock, $3.60 Series"  (the "$3.60 Series  Preferred Stock"), which  is
entitled  to  three votes  per  share) upon  each  matter presented  at  the NSP
Meeting. On  the NSP  Record Date,  there were  275,000 shares  of $3.60  Series
Preferred Stock outstanding.

    A  majority of  the voting  power of the  shares issued  and outstanding and
entitled to vote, present in person or  by proxy, shall constitute a quorum  for
the transaction of business at the NSP Meeting. Abstentions and broker non-votes
(i.e.,  proxies from brokers  or nominees indicating that  such persons have not
received instructions from the  beneficial owners or  other persons entitled  to
vote shares as to a matter with respect to which brokers or nominees do not have
discretionary power to vote) will be

                                       28
<PAGE>
considered  present for  the purpose of  establishing a  quorum. The affirmative
vote of a  majority of  the votes  entitled to  be cast  by the  holders of  the
outstanding shares of NSP Common Stock and NSP Preferred Stock entitled to vote,
voting  as a single class, is required to approve the Merger Agreement. Approval
of the Merger  Agreement is a  condition to consummation  of the Mergers.  Under
applicable  Minnesota  law,  in  determining whether  the  Merger  Agreement has
received the  requisite  number of  affirmative  votes, abstentions  and  broker
non-votes will have the same effect as votes cast against approval of the Merger
Agreement.

    Shareholders   are  entitled  to  vote  cumulatively  for  the  election  of
directors. Each shareholder is entitled to  a number of votes for such  election
equal to the number of votes entitled to be cast with respect to the shares held
by such shareholder multiplied by the number of directors to be elected, and may
cast  all votes for one nominee or  distribute the votes among the nominees. The
election of each director shall be decided  by plurality vote. As a result,  any
shares  not  voted  for a  director  (whether by  withholding  authority, broker
non-vote or otherwise) will have no  impact on the election of directors  except
to  the extent  that the failure  to vote  for an individual  results in another
individual receiving a larger number of votes.

    The affirmative vote of a majority of  the votes entitled to be cast by  the
holders of the shares of NSP Common Stock and NSP Preferred Stock represented at
the NSP Meeting and entitled to vote thereon, voting as a single class (PROVIDED
that  the total  vote cast represents  over 50% of  the voting power  of all the
shares of NSP Common Stock and NSP Preferred Stock entitled to vote thereon)  is
required  to approve the Primergy Stock  Incentive Plan, the Primergy Management
Incentive Compensation  Plan,  the  ratification of  the  appointment  of  Price
Waterhouse  LLP as  NSP's independent accountants  for 1995  and the Shareholder
Proposals. Abstentions from voting on such matters are treated as votes against,
while broker non-votes are treated as shares not entitled to vote.

    The directors and executive officers of NSP, together with their  affiliates
as  a group, own beneficially less than  1% of the issued and outstanding shares
of NSP Common Stock  and less than  1% of the issued  and outstanding shares  of
each  series of  NSP Preferred  Stock. First Trust  N.A., the  Trustee for NSP's
Employee Stock Ownership Plan (the "NSP ESOP"), holds approximately 8.41% of the
NSP Common Stock for the  benefit of NSP ESOP participants,  none of whom has  a
total   beneficial  interest  of  more  than  5%  of  NSP's  outstanding  voting
securities. No  other  person  holds of  record  or,  to the  knowledge  of  NSP
management,  owns  beneficially more  than 5%  of any  class of  the outstanding
voting securities of NSP.

    If an NSP shareholder is a participant in the NSP ESOP, the participant will
receive an NSP ESOP voting directive  for shares allocated to the  participant's
account  under the NSP ESOP. The trustee for  the NSP ESOP will vote such shares
as instructed by the participant in his  or her NSP ESOP voting directive. If  a
participant  in the NSP ESOP  does not return an  NSP ESOP voting directive, the
trustee for the NSP ESOP will vote such participant's allocated NSP ESOP shares,
along with all unallocated shares held in  the NSP ESOP, in the same  proportion
that all allocated shares in the NSP ESOP are voted.

    If  an NSP shareholder is a participant in the NSP Dividend Reinvestment and
Stock Purchase Plan (the  "NSP DRIP"), the NSP  proxy will represent the  shares
held  on behalf of  the participant under the  NSP DRIP and  such shares will be
voted in accordance with the instructions on the NSP proxy. If a participant  in
the  NSP DRIP does not return an NSP proxy, the participant's shares will not be
voted.

    PROXIES.  Holders of the NSP Common  Stock and NSP Preferred Stock may  vote
either  in person or by properly executed proxy. By completing and returning the
form of proxy, the NSP shareholder authorizes the persons named therein to  vote
all  the NSP shareholder's shares  on his or her  behalf. Issued and outstanding
shares of NSP Common  Stock and NSP  Preferred Stock, the  holders of which  are
entitled  to vote at the NSP Meeting, which are represented by properly executed
proxies, will, unless  such proxies have  been revoked, be  voted in  accordance
with  the  instructions  indicated  in  such  proxies.  If  no  instructions are
indicated,  such   shares   will  be   voted   FOR  approval   of   the   Merger

                                       29
<PAGE>
Agreement,  FOR  the approval  of  the Primergy  Stock  Incentive Plan,  FOR the
approval of  the  Primergy  Management  Incentive  Compensation  Plan,  FOR  the
election  of the  nominated directors,  FOR ratification  of the  appointment of
Price Waterhouse LLP as NSP's independent accountants for 1995 and AGAINST  each
of  the Shareholder  Proposals. With  respect to  the election  of the nominated
directors, the persons  named as  proxies reserve  the right  to cumulate  votes
represented by proxies which they receive and to distribute such votes among one
or  more of  the nominees at  their discretion.  A NSP shareholder  may revoke a
proxy at any time prior to the NSP Meeting by delivering to the Secretary of NSP
a notice of  revocation or  a duly  executed proxy bearing  a later  date or  by
attending  the NSP Meeting and  voting in person. Attendance  at the NSP Meeting
will not in itself constitute revocation of a proxy.

    NSP will bear  the cost of  soliciting proxies for  the NSP Meeting,  except
that  NSP  and WEC  shall  share equally  expenses  incurred in  connection with
printing and  filing this  Joint Proxy  Statement/ Prospectus.  See "The  Merger
Agreement  -- Expenses." In addition to soliciting proxies by mail, officers and
employees of  NSP,  without  receiving  additional  compensation  therefor,  may
solicit  proxies by telephone,  by telecopy, by  telegram or in  person. NSP has
retained D.F. King & Co.,  Inc. to aid in the  solicitation of proxies from  the
NSP shareholders. The fee for such services of such firm shall be $6,500 plus an
additional  $3.00  per  shareholder  contact  and  reimbursement  for reasonable
out-of-pocket expenses.

    The NSP Meeting may be adjourned to another date and/or place for any proper
purpose (including, without limitation, for the purpose of soliciting additional
proxies).

WEC MEETING

    PURPOSE OF WEC MEETING.  The purpose  of the WEC Meeting is to consider  and
vote  upon: (i) a proposal to approve  the Merger Agreement and the transactions
contemplated thereby (including, among other  things, the issuance of shares  of
Primergy  Common Stock pursuant  to the terms  of the Merger  Agreement); (ii) a
proposal to approve the Name Change  Amendment; (iii) a proposal to approve  the
Common  Stock Amendment; (iv) a proposal  to aprove the Primergy Stock Incentive
Plan; (v) a proposal to  approve the Primergy Management Incentive  Compensation
Plan;  and (vi) such other matters, if any,  as may properly come before the WEC
Meeting. The WEC Board  is not aware, as  of the date of  mailing of this  Joint
Proxy  Statement/Prospectus, of any other matters which may properly come before
the WEC  Meeting. The  WBCL  provides that  only  business within  the  purposes
described  in the Notice of the WEC Meeting may be conducted at the WEC Meeting.
If any other matters properly come before the WEC Meeting, or any adjournment or
postponement thereof, it is the intention of  the persons named in the proxy  to
vote such proxies in accordance with their best judgment on such matters.

    The  WEC  Board, by  unanimous  vote, has  adopted  and approved  the Merger
Agreement, each of the WEC Articles  Amendments and each of the Primergy  Plans,
and  recommends that WEC shareholders vote  FOR approval of the Merger Agreement
(including the issuance of shares of Primergy Common Stock pursuant to the terms
of the Merger Agreement),  FOR approval of each  of the WEC Articles  Amendments
and FOR approval of each of the Primergy Plans.

    Pursuant to the Merger Agreement, consummation of the Mergers is conditioned
upon  approval by the shareholders of WEC of proposals (i) through (v) set forth
above. NSP and WEC retain the right to  waive the approval of either or both  of
the Primergy Plans (proposals (iv) and (v) above), or the approval of the Common
Stock Amendment (proposal (iii) above), as conditions to the consummation of the
Mergers. If approved, each of the WEC Articles Amendments will become effective,
and  each of  the Primergy Plans  will be  implemented, only if  the Mergers are
consummated.

    DATE, PLACE AND TIME; RECORD DATE.  The WEC Meeting is scheduled to be  held
on  Wednesday, September 13, 1995,  at 9:00 a.m., local  time, in the Exhibition
Hall of  The  Grand  Milwaukee  Hotel,  4747  South  Howell  Avenue,  Milwaukee,
Wisconsin.  Holders of  record of  shares of  WEC Common  Stock at  the close of
business on July 27, 1995,  the WEC Record Date, will  be entitled to notice  of
and

                                       30
<PAGE>
to vote at the WEC Meeting. As of the WEC Record Date, 109,936,834 shares of WEC
Common  Stock  were issued  and  outstanding and  entitled  to vote.  A  list of
shareholders of record entitled to vote at the WEC Meeting will be available for
inspection by WEC shareholders  at WEC's principal business  office at 231  West
Michigan  Street, Milwaukee, Wisconsin  prior to the WEC  Meeting. The list will
also be available on the day of the WEC Meeting at the meeting site.

    VOTING RIGHTS.  Each  outstanding share of WEC  Common Stock is entitled  to
one  vote upon each matter presented at the WEC Meeting. A majority of the votes
entitled to be cast  by holders of  shares of WEC  Common Stock, represented  in
person  or by proxy, shall constitute a  quorum for each matter presented at the
WEC Meeting. Abstentions  and broker  non-votes (I.E., proxies  from brokers  or
nominees  indicating that such  persons have not  received instructions from the
beneficial owners or other persons entitled to  vote shares as to a matter  with
respect  to which brokers or  nominees do not have  discretionary power to vote)
will be considered present for the purpose of establishing a quorum.

    If a quorum is present, (i) the affirmative vote of a majority of the  votes
entitled to be cast by the holders of the shares of WEC Common Stock represented
at  the WEC Meeting and  entitled to vote thereon  (PROVIDED that the total vote
cast represents over 50% of all the shares of WEC Common Stock entitled to vote)
is required for  approval of  the Merger  Agreement (including  the issuance  of
shares  of Primergy Common Stock pursuant to  the terms of the Merger Agreement)
and the Primergy Stock Incentive Plan,  (ii) the affirmative vote of a  majority
of  the votes  entitled to  be cast  at the  WEC Meeting  by the  holders of the
outstanding shares of WEC Common Stock entitled to vote thereon is required  for

of a majority of the votes entitled to  be cast by the holders of the shares  of
WEC  Common Stock represented at the WEC Meeting and entitled to vote thereon is
required for approval of the Primergy Management Incentive Compensation Plan. As
to each proposal before shareholders at  the WEC Meeting, abstentions will  have
the same effect as votes cast against approval of the proposal. Broker non-votes
will  have the  same effect as  votes cast against  approval of each  of the WEC
Articles Amendments but will not be counted as votes entitled to be cast by  the
holders of shares of WEC Common Stock present or represented by proxy at the WEC
Meeting in determining whether holders of a majority of such votes have voted to
approve the Merger Agreement and each of the Primergy Plans. Failure to return a
WEC  proxy or vote in person  at the WEC Meeting will  have the effect of a vote
against each  of  the  WEC  Articles Amendments.  The  directors  and  executive
officers  of WEC, together with  their affiliates as a  group, are deemed to own
less than 1% of the issued and outstanding shares of WEC Common Stock.

    PROXIES.  Holders of the  WEC Common Stock may vote  either in person or  by
properly  executed proxy. By completing and returning the form of proxy, the WEC
shareholder  authorizes  the  persons  named   therein  to  vote  all  the   WEC
shareholder's  shares on his  or her behalf. All  completed WEC proxies returned
will be voted in accordance with the instructions indicated on such proxies.  If
no  instructions are given,  the WEC proxies  will be voted  FOR approval of the
Merger Agreement  (including the  issuance of  shares of  Primergy Common  Stock
pursuant  to the terms of the Merger  Agreement), FOR approvalof each of the WEC
Articles Amendments and FOR approval of each of the Primergy Plans. A WEC  proxy
may  be revoked  by voting in  person at the  WEC Meeting, by  written notice to
WEC's Corporate Secretary, or by delivery  of a later-dated proxy, in each  case
prior  to the closing of the polls for  voting at the WEC Meeting. Attendance at
the WEC Meeting will not in itself constitute revocation of a proxy.

    If a WEC shareholder  is a participant in  WEC's Stock Plus Investment  Plan
("Stock  Plus") or owns shares through investments  in the WEC Common Stock Fund
of WEPCO's Management  Employee Savings  Plan ("MESP")  or Represented  Employee
Savings  Plan ("RESP"), the WEC proxy will  serve as voting instructions for the
participant's shares  held  in  those plans,  as  well  as a  proxy  for  shares
registered  in the participant's name. Shares of plan participants will be voted
by the  administrator for  Stock  Plus and  the trustee  for  MESP and  RESP  in
accordance with such participant's proxies/voting instructions. If a participant
in Stock Plus does not return a WEC proxy, the administrator for Stock Plus will
not  vote such participant's shares held in  Stock Plus. If a participant in the

                                       31
<PAGE>
WEC Common Stock Fund of MESP (the "MESP Fund") or the WEC Common Stock Fund  of
RESP  (the "RESP Fund") does not return a  WEC proxy, the trustee for such plans
will vote such participant's shares held in  the MESP Fund or RESP Fund, as  the
case  may be, in  the same proportion that  all shares in the  MESP Fund or RESP
Fund, as the case may be, are voted.

    WEC will bear the cost of the  solicitation of proxies for the WEC  Meeting,
except that NSP and WEC shall share equally expenses incurred in connection with
printing  and  filing this  Joint  Proxy Statement/Prospectus.  See  "The Merger
Agreement --  Expenses."  Proxies  may  be solicited  by  certain  officers  and
employees  of WEC or  its subsidiaries by  mail, by telephone,  personally or by
other communications, without compensation apart from their normal salaries. WEC
has retained D.F. King & Co., Inc. to assist in the solicitation of proxies from
WEC shareholders, including  brokers' accounts, at  a fee for  such services  of
$6,500   plus  an  additional  $3.00  per  shareholder  contact  and  reasonable
out-of-pocket expenses.

    The WEC Meeting may be adjourned to another date and/or place for any proper
purpose (including, without limitation, for the purpose of soliciting additional
proxies).

                                  THE MERGERS

BACKGROUND OF THE MERGERS

    WEC  and  NSP  both  believe  that  fundamental  changes  in  the regulatory
structure of the electric utility industry are inevitable and that such  changes
will  likely occur in the near future.  Recently enacted federal laws and recent
actions by federal and state regulatory commissions are facilitating the changes
to bring more competition to various segments of the industry.

    The Energy  Policy  Act  of 1992  (the  "1992  Act") granted  the  FERC  the
authority  to order electric utilities to  provide transmission service to other
utilities and  to other  buyers  and sellers  of  electricity in  the  wholesale
market.  The  1992 Act  also  created a  new  class of  power  producers, exempt
wholesale generators ("EWGs"), which are  exempt from regulation under the  1935
Act.  The exemption from regulation under the 1935 Act of EWGs has increased the
number  of  entrants  into  the  wholesale  electric  generation  market,   thus
increasing  competition  in  the  wholesale  segment  of  the  electric  utility
industry.

    Commencing in December 1993, pursuant to  its authority under the 1992  Act,
FERC  issued a number of orders in specific cases directing utilities to provide
transmission services. Under  FERC's evolving  transmission policies,  utilities
are  being required to offer  transmission services to third  parties on a basis
comparable to services that the utilities provide themselves. On April 7,  1995,
FERC  issued  a  notice  of  proposed  rulemaking  under  which  it  proposed to
implement,  on  a  comprehensive  basis,  the  comparable  transmission  service
policies  it has  set forth in  specific cases.  FERC's actions to  date and its
transmission  rulemaking   proceeding  have   increased  the   availability   of
transmission  services, thus creating greater competition in the wholesale power
market.

    In addition, state  regulatory bodies  in certain  states, including,  among
others,  California,  Minnesota  and Wisconsin,  have  initiated  proceedings to
review the  basic  structure  of  the industry.  These  bodies  are  considering
proposals  to require some measure  of competition in the  retail portion of the
industry. The Wisconsin Commission requested comments regarding how the industry
might be  restructured  in  order  to create  a  more  competitive  environment.
Following receipt of responses, the Wisconsin Commission created a task force to
analyze  how the industry might be  restructured in Wisconsin to allow consumers
to  receive  the  benefits  of   increased  competition.  While  the   Wisconsin
Commission's  proceedings  and  the  various other  state  proceedings  have not
concluded, it  is  the  view  of  the managements  of  NSP  and  WEC  that  such
proceedings  will result in some measure  of increased competition in the retail
segment of the business.

    The changes  to  the electric  industry  that  have occurred  and  that  are
occurring  are bringing increased competition to various sectors of the business
and are putting pressure  on utilities to  lower their costs.  Both NSP and  WEC
recognized  that  a combination  with another  financially strong  utility would
enable the  combined entity  to generate  and deliver  energy more  cheaply  and
efficiently  and thereby remain a premier  supplier of energy in an increasingly
deregulated industry.

    For a description of certain preexisting business relationships between  WEC
and  NSP, see "Selected  Information Concerning WEC and  NSP -- Certain Business
Relationships Between WEC and NSP."

    Beginning in the  spring of  1994, the  management of  NSP analyzed  various
potential  strategic options that might be  available to NSP, including possible
business combinations with other  utilities. Beginning in  late summer of  1994,
management was assisted in this process by the Management Consulting Division of
Deloitte  & Touche LLP ("Deloitte  & Touche"). The NSP  Board was briefed at its
August 1994  meeting  with  respect to  the  work  that had  been  done  by  NSP
management in assessing the industry environment and analyzing various potential
merger  partners and possible legal structures.  The management of NSP looked at
substantially all of the  utilities of significant size  and with service  areas
proximate  to the main service areas of NSP. None of the other utilities offered
synergy opportunities of the magnitude that  could be realized through a  merger
with  WEC. The physical proximity of the service areas of WEC, the compatibility
of and similarity between NSP's and

                                       33
<PAGE>
WEC's operations and the excellent reputation  of WEC's management made WEC  the
natural  first choice for  a combination partner for  NSP. No alternative merger
scenarios were seriously considered at or after this time.

    In September 1994,  Mr. Edwin  Theisen, then-President  and Chief  Operating
Officer  of NSP,  raised the concept  of a combination  of NSP and  WEC with Mr.
Abdoo, Chairman, President and Chief Executive Officer of WEC, at the suggestion
of Mr. Howard, Chairman and Chief Executive Officer of NSP. That led to a series
of discussions between Messrs. Abdoo and Theisen which ultimately resulted in  a
meeting at the end of October 1994 between Messrs. Howard, Abdoo and Theisen, at
which  the  two companies'  views of  the  future of  the utility  industry were
discussed. The three men discussed in a very preliminary fashion the concept  of
a  business combination, structured as a merger  of equals, between NSP and WEC.
They also identified the issues of management succession, board composition  and
the location of the headquarters as significant points to be agreed upon.

    Shortly  after  the  October 1994  meeting,  NSP  engaged the  law  firms of
Gardner, Carton & Douglas and Wachtell, Lipton,  Rosen & Katz to advise it  with
respect to the potential transaction.

    Shortly  after the  October 1994  meeting, WEC  management reviewed possible
strategic alternatives for WEC, including  a business combination with NSP,  the
possibility  of  remaining  an  independent company  and  the  possibility  of a
combination with  another Midwestern  utility. No  alternative merger  scenarios
were  seriously  considered  by  WEC  management.  There  was  a  review  of the
consequences of WEC remaining an independent company. WEC sought advice from the
investment banking firm of Barr Devlin and the law firms of Quarles & Brady  and
Skadden, Arps, Slate, Meagher & Flom with respect to strategic alternatives. The
WEC Board was briefed at its November 1994 meeting with respect to the fact that
WEC  management was  reviewing various  strategic alternatives  mentioned above,
including a possible business  combination with NSP,  and that management  would
report back to the WEC Board.

    In late November 1994, representatives of WEC advised representatives of NSP
that WEC management was interested in exploring the possibility of a combination
of the two companies, but WEC felt that it needed to perform additional internal
analysis  of the potential benefits of the transaction before it further engaged
NSP in any substantive discussions.

    In December 1994, NSP management briefed  the NSP Board with respect to  its
analysis of the potential synergies that could be achieved by a combination with
WEC  or  other utilities  (such  as cost  savings  from economies  of  scale and
decreased  fuel  costs,  reduction  in  operational  and  maintenance  expenses,
integration  of nuclear facilities and elimination of duplicative administrative
expenditures),  and  the  legal  and  regulatory  implications  of   alternative
combination structures.

    Representatives  of WEC  contacted representatives  of NSP  in early January
1995 and  indicated  that WEC  was  interested in  proceeding  with  discussions
concerning  a possible merger of equals. Messrs. Howard and Abdoo met on January
6, 1995,  at  which meeting  Mr.  Abdoo indicated  that  WEC was  interested  in
proceeding  with the  discussions. The parties  agreed that it  was desirable to
arrange an introductory meeting of the parties' respective management teams  and
advisors  to  discuss, among  other things,  the  due diligence  and negotiation
process.

    On January 10, 1995, NSP engaged  Goldman Sachs as its financial advisor  in
connection with the possible transaction.

    An   introductory  meeting  was  held  on  January  12,  1995,  attended  by
representatives of WEC and NSP and their respective counsel, financial  advisors
and  consultants. Working groups  composed of representatives  of both companies
were formed to examine various  issues including structure, financial  modeling,
regulatory considerations, integration of employee benefit plans, communications
and an analysis of synergies.

                                       34

    Shortly  after  the meeting,  the companies  entered into  a confidentiality
agreement,  pursuant  to  which  the  parties  agreed  to  exchange   non-public
information  with a view toward exploring a possible business combination. For a
description of certain standstill  provisions contained in such  confidentiality
agreement, see "The Merger Agreement -- Standstill Provisions."

    Deloitte  & Touche was engaged  to assist the senior  managements of NSP and
WEC and  certain  employees designated  by  them (collectively,  the  "synergies
working  group") in identifying and quantifying  the potential cost savings from
synergies resulting from the proposed merger.

    On January 25, 1995, the NSP Board met with NSP's advisors.  Representatives
of  Goldman Sachs  discussed their views  on changing conditions  in the utility
industry and the financial profiles of  the two companies. Management set out  a
proposed  timetable and  legal counsel  for NSP  explained the  directors' legal
responsibilities. The NSP Board discussed the potential benefits to shareholders
of NSP (in the form of enhanced opportunities for earnings and dividend  growth)
and  customers of  NSP (in  the form of  maintenance of  competitive rates) that
could result from the proposed combination and encouraged management to  proceed
with the process.

    On  January 25, 1995, the WEC Board met with WEC's advisors. Representatives
of Barr Devlin discussed  the status of the  utility industry and the  financial
profiles  of the two companies.  Management explained the financial, structural,
regulatory and synergy  analyses being  undertaken and the  timetable for  their
completion.   Legal   counsel   for   WEC   described   the   directors'   legal
responsibilities. The  WEC  Board  discussed  the  rationale  for  the  proposed
combination and agreed that management should continue the analyses.

    During  the next several weeks, the various task forces continued their work
with respect  to  the  synergies analysis,  business  plans,  legal  structures,
regulatory  plans, due diligence and employee benefits. In addition, discussions
continued between the NSP management and Goldman Sachs on the one hand, and  WEC
management and Barr Devlin on the other hand, with respect to negotiation of the
exchange ratio, and between counsel for WEC and counsel for NSP, with respect to
the terms of the draft merger agreement and stock option agreements.

    On  February  22,  1995,  the  NSP  Board  met  and  received  updates  from
management, Goldman Sachs, legal counsel and consultants. Management reviewed in
detail the NSP five-year  plan, which sets forth  the targeted earnings  growth,
return  on equity and  capital requirements for NSP  and its subsidiaries. Legal
counsel reviewed  the  implications of  adopting  a registered  holding  company
structure  under the 1935 Act, including the possibility that divestiture of the
combined entity's gas and certain non-utility operations would be required.  The
NSP  Board again discussed the potential benefits to shareholders of NSP (in the
form of enhanced opportunities for  earnings and dividend growth) and  customers
of  NSP (in the form of maintenance of competitive rates) that would result from
the combination of NSP and WEC.

    On February 22, 1995, the WEC Board met and were updated by management, Barr
Devlin, legal counsel  and consultants.  Management reviewed  the WEC  five-year
plan  in  detail, which  was composed  of  income, balance  sheet and  cash flow
information. Barr  Devlin reviewed  the  NSP five-year  plan and  the  valuation
methodologies  that it would  apply in evaluating  whether a particular exchange
ratio would, in its opinion, be fair to WEC shareholders. Legal counsel reviewed
the due diligence process and status of discussions concerning the structure  of
any  transaction with NSP,  including the implications  of becoming a registered
holding company under the 1935 Act, and the possibility that divestiture of  the
combined  entity's gas and certain non-utility operations would be required. The
WEC Board  discussed the  potential benefits  to shareholders  (in the  form  of
enhanced  opportunities for earnings and dividend  growth) and customers (in the
form of  maintenance of  competitive rates)  of WEC  which would  result from  a
combination of WEC and NSP.

    On  March 7, 1995, the  WEC Board met and  received further updates. The WEC
Board received a  status report  on the  synergies working  group's analysis  of
potential  synergies,  which  indicated  that the  combination  could  result in
synergies,  net  of   costs  to   achieve  such   synergies,  of   approximately

                                       35
<PAGE>
$2  billion over a ten-year period. Barr Devlin gave a report concerning certain
pro forma financial information for  WEC and NSP and  provided an update on  the
valuation  methodologies that it would apply  in evaluating whether a particular
exchange ratio would, in its opinion, be fair to WEC shareholders. The WEC Board
discussed the potential  benefits to customers  (in the form  of maintenance  of
competitive  rates) and shareholders (in the  form of enhanced opportunities for
earnings and dividend growth) of WEC that would result from a combination of WEC
and NSP and the  significant issues under discussion  between management of  WEC
and NSP.

    The  NSP Board met and  received further updates on  March 10, 1995. The NSP
Board received a  status report  on the  synergies working  group's analysis  of
potential  synergies,  which  indicated  that the  combination  could  result in
synergies, net of costs to achieve  such synergies, of approximately $2  billion
over  a ten-year period.  Legal counsel reviewed generally  the structure of the
merger agreement and stock  option agreements under  discussion between the  two
parties.  The potential benefits to shareholders of NSP (in the form of enhanced
opportunities for earnings  and dividend growth)  and customers of  NSP (in  the
form of maintenance of competitive rates) were again discussed by the NSP Board.

    On  March 14, 1995, Mr. Howard met with the WEC Board and reviewed with them
his perspective on the utility industry  generally, the business of NSP and  its
subsidiaries and the proposed business combination.

    During  the next several days, discussions between management of WEC and NSP
continued regarding the exchange ratio,  the management succession plan and  the
transition  process  between  execution  of a  definitive  merger  agreement and
consummation of the transaction.  Despite repeated efforts,  the two sides  were
unable  to bridge  their differences  on these issues.  Mr. Howard  told the NSP
directors that he did not believe  that at that point an adequate  understanding
had been reached between the specific management teams which would allow for the
development  of the high level of cooperation necessary to realize the potential
synergies and that,  in his  view, the discussions  had reached  an impasse  and
should be terminated. Mr. Howard so advised Mr. Abdoo on March 20, 1995. The NSP
decision  to terminate discussions was confirmed by a letter dated the same day.
By letter dated March 27, 1995, WEC acknowledged NSP's March 20, 1995 letter.

    The WEC Board met  on March 21,  1995 and was briefed  by management on  the
breakdown of the discussions. The WEC Board discussed the issues that led to the
impasse between WEC and NSP and the potential benefits to customers (in the form
of  maintenance of competitive rates) and  shareholders (in the form of enhanced
opportunities for earnings and dividend growth)  of WEC which could result  from
the  combination.  The  WEC Board  concluded  that,  in light  of  the potential
benefits to shareholders and customers of WEC of a business combination  between
NSP  and WEC,  the WEC  Board would  be interested  in further  exploration of a
possible business combination between  NSP and WEC if  the open issues could  be
resolved on an acceptable basis.

    Representatives  of WEC  advised representatives of  NSP that  the WEC Board
remained supportive of the transaction and urged that representatives of the two
companies be authorized to meet to attempt to resolve the open issues.

    The NSP Board met  on March 24,  1995 and was briefed  by management on  the
breakdown  of discussions and the message communicated  by the WEC Board. It was
the sense of the NSP Board at that meeting that, while the business logic of the
transaction in  terms of  the  possible synergies  was quite  compelling,  those
synergies  could only be realized if the  transition to a combined company could
be effected smoothly and economically.

    Representatives of NSP  contacted representatives  of WEC  and advised  them
that  it was the view of the NSP  Board that Messrs. Howard and Abdoo themselves
should meet to see  whether the impasse reached  in negotiating the  transaction
could  be overcome. A meeting between Messrs. Abdoo and Howard was held on March
30, 1995 at which  there was discussion  of the reasons for  the impasse in  the
discussions,  the issues that led  to the impasse and  the potential benefits to
shareholders and

                                       36
<PAGE>
customers of  both  WEC  and  NSP from  the  combination,  namely  the  enhanced
opportunities  for shareholders to achieve earnings and dividend growth, and the
maintenance of competitive  rates for  customers. Messrs. Howard  and Abdoo  met
again on April 4, 1995 with other representatives of the parties to review those
issues.  Several meetings and discussions were then held between representatives
of the two  parties over  the next  two weeks on  the issues  of transition  and
management  succession. Messrs. Howard and Abdoo met again on April 17, 1995 and
at that meeting confirmed  their understandings on  those issues. Messrs.  Abdoo
and  Howard  directed their  advisors to  meet to  discuss any  remaining issues
between the parties and the proposed schedule. The lawyers and management  teams
for the two sides met on April 18, 1995 and confirmed the understandings reached
by  Messrs. Howard and Abdoo. On April 19, 1995, the WEC Board formally approved
the reopening  of  the  discussions  between  the  parties.  The  parties  later
confirmed  the reopening of discussions  as of such date  in an amendment to the
confidentiality agreement.

    The advisors for  both parties  met and spoke  several times  over the  next
week,  discussing the transaction and the related documentation, agreed upon the
proposed structure for the  transaction and negotiated the  terms of the  Merger
Agreement,  including the conditions to closing, the termination provisions, the
break-up fees, the covenants  which would govern the  operations of NSP and  WEC
prior to the Effective Time and various other matters, such as employee benefits
and  workforce matters, which would govern  the operations of Primergy after the
Effective Time.  Goldman Sachs  and Barr  Devlin held  further discussions  with
respect  to the exchange ratio and agreed  to recommend to their clients a ratio
which would result in each company's  common shareholders as a group owning  50%
of the surviving company's common equity.

    On  April 26, 1995, Mr. Abdoo met with  the NSP Board and reviewed with them
his views  on  the utility  industry  generally, the  business  of WEC  and  its
subsidiaries and the proposed business combination.

    On  April 26, 1995, the WEC Board met and received detailed advice from Barr
Devlin, legal counsel and an outside employee benefits consultant. The WEC Board
also received an updated status report on the synergies working group's analysis
of potential synergies,  including discussions  of potential  cost savings  from
economies  of scale and decreased fuel  costs, integration of nuclear facilities
and elimination  of duplicative  administrative expenses.  Barr Devlin  reviewed
financial and other information concerning NSP and WEC and the proposed exchange
ratio.  Counsel  outlined  in detail  the  terms  and conditions  of  the Merger
Agreement and Stock Option Agreements. Counsel also reviewed the succession plan
contained in the  Merger Agreement  and the  handling of  various social  issues
relating  to the transaction, such as the  composition of the Primergy Board and
the location of  the corporate  headquarters of Primergy.  The outside  employee
benefits  consultant  reviewed  the terms  of  the employment  agreements  to be
entered into  by  Primergy upon  consummation  of the  Mergers  as well  as  the
Severance  Policies covering certain  senior executives of NSP  and WEC. The WEC
Board discussed  the  significant  potential  benefits  from  a  combination  to
shareholders and customers of WEC and NSP.

    On April 28, 1995, at a meeting of the NSP Board, counsel to NSP outlined in
detail  the  terms  and conditions  of  the  Merger Agreement  and  Stock Option
Agreements. Counsel also  reviewed the  succession plan outlined  in the  Merger
Agreement  and  the  handling  of  the various  social  issues  relating  to the
transaction, such as the composition of  the Primergy Board and the location  of
the  headquarters of the combined entity. The NSP Board also received an updated
status report  on  the  synergies  working group's  analysis  of  the  potential
synergies,  and management reviewed  the regulatory plan.  An outside consultant
reviewed with the directors the terms  of the employment agreements proposed  to
be  entered into by  Primergy upon consummation  of the Mergers,  as well as the
Severance Policies covering the senior executives  of NSP and WEC. At the  April
28  meeting, Goldman Sachs delivered its oral  opinion to the NSP Board that, as
of such date and based upon and  subject to the matters discussed, the  proposed
exchange  ratio of 1.626 shares of Primergy Common Stock per share of NSP Common
Stock was fair to the holders of  NSP Common Stock. A committee composed of  all
of  the directors other than Messrs. Howard and Theisen was formed to review the
transactions and make a

                                       37
<PAGE>
recommendation with respect thereto to the entire NSP Board. Such committee  met
and  approved  the Merger  Agreement  and the  Stock  Option Agreements  and the
transactions contemplated  thereby. The  NSP Board  discussed the  presentations
they  had  received  and,  upon  conclusion,  unanimously  approved  the  Merger
Agreement and the Stock Option Agreements and authorized their execution.

    On April 28, 1995, the  WEC Board met and  received advice from Barr  Devlin
and  legal counsel. Barr Devlin reviewed various financial and other information
and rendered to the WEC Board its opinion to the effect that, as of the date  of
said  opinion and  based upon  and subject  to the  matters stated  therein, the
proposed exchange ratio of  1.626 shares of Primergy  Common Stock per share  of
NSP  Common Stock was fair  to the holders of WEC  Common Stock from a financial
point of view. Legal  counsel reviewed the final  forms of Merger Agreement  and
Stock  Option Agreements and other transaction documents with the WEC Board. The
WEC Board  discussed the  advice they  had  received at  the various  WEC  Board
meetings and the significant potential benefits to shareholders and customers of
WEC  which  would  result  from  a  combination  of  WEC  and  NSP.  After  such
discussions, the WEC  Board unanimously  approved the Merger  Agreement and  the
Stock Option Agreements and authorized their execution.

    Following  the  meetings of  the NSP  Board  and the  WEC Board,  the Merger
Agreement and the Stock Option Agreements were executed.

REASONS FOR THE MERGERS; RECOMMENDATIONS OF THE BOARDS OF DIRECTORS

    NSP and  WEC  believe  that  the Mergers  offer  the  following  significant
strategic  and  financial  benefits  to each  company  and  to  their respective
shareholders, as well as to their employees and customers and the communities in
which they do business:

        - MAINTENANCE OF COMPETITIVE  RATES -- Primergy  will be able  to
          meet the challenges of the increasingly competitive environment
          in the utility industry more effectively than either WEC or NSP
          standing  alone. The  Mergers will  create the  opportunity for
          strategic, financial and operational benefits for customers  in
          the form of lower rates over the long term and for shareholders
          in  the  form  of  greater  financial  strength  and  financial
          flexibility.

        - INTEGRATION  OF  CORPORATE  AND  ADMINISTRATIVE  FUNCTIONS   --
          Primergy  would be  able to  consolidate certain  corporate and
          administrative functions of  NSP and  WEC, thereby  eliminating
          duplicative  positions, reducing other  non-labor corporate and
          administrative  expenses  and  limiting  or  avoiding   capital
          expenditures  for  administrative  facilities  and  information
          systems. In addition, it is anticipated that a large portion of
          the corporate  and  administrative functions  of  NSP-Wisconsin
          could  be eliminated or performed  by WEPCO. A joint transition
          task force is examining  the manner in  which to best  organize
          and  manage the businesses of Primergy and identify duplicative
          positions in  the corporate  and  administrative areas.  It  is
          anticipated  that,  as a  result of  combining staff  and other
          functions, Primergy will  have fewer  employees within  several
          years than NSP and WEC currently have in the aggregate. NSP and
          WEC  are  committed  to achieve  cost  savings in  the  area of
          personnel reductions  through  attrition,  strictly  controlled
          hiring,   reassignment  and  retraining   and,  to  the  extent
          required, severance and targeted early retirement programs.  In
          addition,   some  savings  in  areas   such  as  insurance  and
          regulatory costs and legal, audit and consulting fees should be
          realized.

        - EXPANDED MANAGEMENT RESOURCES  -- In combination,  WEC and  NSP
          will  be able  to draw  on a larger  and more  diverse mid- and
          senior-level management pool to

                                       38
<PAGE>
          lead  Primergy   forward   in   an   increasingly   competitive
          environment  for the  delivery of  energy and  should be better
          able to attract  and retain the  most qualified employees.  The
          employees   of   Primergy   should   also   benefit   from  new
          opportunities in the expanded organization.

        - INTEGRATION OF NUCLEAR OPERATIONS -- The centralization of  the
          management,  supervision  and  operation of  NSP's  and WEPCO's
          separate nuclear generating facilities should avoid duplication
          and enhance effectiveness in making and implementing  decisions
          affecting   nuclear  operations   without  compromising  public
          safety.

        - PURCHASING ECONOMIES  AND STREAMLINING  OF INVENTORIES  --  The
          combination  of  the  two companies  should  result  in greater
          purchasing powers  for items  such as  fuel and  transportation
          services  and  the  reduction of  inventories  for standardized
          materials  and  supplies  for  construction,  operations,   and
          maintenance  within the  combined generation,  transmission and
          distribution systems.

        - COORDINATION OF DIVERSIFICATION  PROGRAMS -- NSP  and WEC  each
          have  significant non-utility subsidiaries,  and Primergy, as a
          stronger financial entity, should be able to manage and  pursue
          such subsidiary businesses more efficiently and effectively.

        - MORE   DIVERSE  SERVICE  TERRITORY   --  The  combined  service
          territories of NSP and  WEPCO will be  larger and more  diverse
          than  either  of the  service territories  of  NSP or  WEPCO as
          independent entities.  This  increased  geographical  diversity
          will reduce the exposure to changes in economic, competitive or
          climatic conditions in any given sector of the combined service
          territory.

        - COMMUNITY  INVOLVEMENT  --  Primergy will  continue  to  play a
          strong  role  in  the  economic  development  efforts  of   the
          communities  NSP  and  WEC  now  serve.  The  philanthropic and
          volunteer programs currently  maintained by  the two  companies
          will be continued.

    Subject  to the  qualifications expressed  below, NSP  and WEC  believe that
synergies from the Mergers will  generate substantial cost savings to  Primergy,
which  would not be  available absent the Mergers.  Preliminary estimates by the
managements of NSP and WEC indicate  that the Mergers could result in  potential
net  cost savings  (that is,  after taking  into account  the costs  incurred to
achieve such savings)  of approximately  $2 billion during  the ten-year  period
following  the Mergers. Approximately one-half of  these savings are expected to
be achieved  through personnel  reductions. Other  potentially significant  cost
savings  include  reduced corporate  and  administrative programs,  reduced fuel
costs, lower  gas supply  costs,  and other  avoided  or reduced  operation  and
maintenance  costs, such as  labor and materials. Achieved  savings in costs are
expected to  inure  to the  benefit  of  both shareholders  and  customers.  The
treatment  of  the benefits  and  cost savings  will  depend on  the  results of
regulatory proceedings in the various jurisdictions in which NSP and WEC operate
their businesses. See "Regulatory Matters."

    The analyses employed in order to develop estimates of potential savings  as
a  result of  the Mergers were  necessarily based upon  various assumptions that
involve judgments  with respect  to,  among other  things, future  national  and
regional  economic  and  competitive  conditions,  inflation  rates,  regulatory
treatment, weather  conditions,  financial market  conditions,  future  business
decisions,  and other uncertainties,  all of which are  difficult to predict and
many of which are beyond the control of NSP and WEC. Accordingly, while NSP  and
WEC believe that such assumptions are reasonable for purposes of the development
of  estimates  of  potential  savings,  there  can  be  no  assurance  that such
assumptions will  approximate actual  experience or  that such  savings will  be
realized.

    NSP.   The NSP Board believes that the terms of the Mergers are fair to, and
in the best interests of, NSP and its shareholders. Accordingly, the NSP  Board,
by a unanimous vote, has approved the

                                       39
<PAGE>
Merger Agreement and recommends its approval and adoption by NSP's shareholders.
The  NSP Board believes: that  the Mergers present a  unique opportunity for NSP
and  WEC  to  combine  as  equals;  that  NSP's  shareholders  will  benefit  by
participation  in  the combined  economic growth  of the  NSP and  WEPCO service
territories, and  from the  inherent  increase in  scale economies,  the  market
diversification  and the  resulting increased financial  stability and strength;
that the  Mergers will  result in  cost  savings from  decreased fuel  costs,  a
reduction  in operational  and maintenance  expense and  other factors discussed
above; and  that the  combined enterprise  can participate  in the  increasingly
competitive  market for the  generation of power.  All of these  factors offer a
potential increase in earnings and dividend growth and the creation of a larger,
financially stronger  company.  In  reaching  its  conclusions,  the  NSP  Board
considered  (i) the  financial performance,  condition, business  operations and
prospects of each of NSP  and WEC and that, on  a combined basis, the  companies
will  likely have greater financial stability  and strength due to participation
in the combined economic climate  and growth of both  the WEPCO and NSP  service
territories,   the   inherent   increase   in   scale   economies,   the  market
diversification resulting from the combination of customer bases and the  impact
of  the potential operating efficiencies and  other synergies which are expected
to reduce operational and maintenance  expenses, as more fully discussed  above;
(ii)   current  industry,  economic,  market  and  regulatory  conditions  which
encourage consolidation  to reduce  risk  and create  new avenues  for  earnings
growth  as discussed  under "The  Mergers --  Background of  the Mergers" above;
(iii) the  anticipated  positive  effect  of the  Mergers  on  shareholders  and
customers;  (iv) the proposed structure of the transaction as a merger of equals
between NSP and  WEC and the  terms of  the Merger Agreement,  the Stock  Option
Agreements,  the Employment  Agreements and other  documents executed  and to be
executed  in  connection   with  the  Mergers   which  provide  for   reciprocal
representations and warranties, conditions to closing and rights to termination,
balanced  rights and  obligations and  protection for  employees of  NSP and the
communities it  serves; (v)  the  management succession  plan specified  in  the
Merger  Agreement and the Employment Agreements  of Messrs. Howard and Abdoo (as
described under "-- Employment Agreements"  and "Primergy Following the  Mergers
--  Management  of Primergy")  which provides  a prudent  plan for  managing the
integration of and transition in management; (vi) the impact of regulation under
various state and federal laws (as described under "Regulatory Matters" and  "--
Background  of the Mergers"); (vii) that the  Mergers are expected to be treated
as a  tax-free reorganization  to shareholders  and  to be  accounted for  as  a
pooling-of-interests  transaction (which avoids the  reduction in earnings which
would result  from the  creation  and amortization  of goodwill  under  purchase
accounting);  and (viii) the opinion of Goldman Sachs, described below, that the
Ratio is fair to holders  of NSP Common Stock.  In determining that the  Mergers
are  fair  to and  in  the best  interests of  its  shareholders, the  NSP Board
considered the above factors as a whole and did not assign specific or  relative
weights to them.

    THE  NSP BOARD  HAS UNANIMOUSLY APPROVED  THE MERGER  AGREEMENT AND BELIEVES
THAT THE TERMS OF THE MERGERS ARE FAIR  TO, AND IN THE BEST INTERESTS OF,  NSP'S
SHAREHOLDERS,  HAS APPROVED EACH OF THE PRIMERGY PLANS, SUPPORTS THE ELECTION OF
THE NOMINATED DIRECTORS, SUPPORTS THE  RATIFICATION OF THE APPOINTMENT OF  PRICE
WATERHOUSE  LLP  AS  NSP'S INDEPENDENT  ACCOUNTANTS  FOR 1995,  AND  OPPOSES THE
SHAREHOLDER PROPOSALS.  THE NSP  BOARD RECOMMENDS  A VOTE  FOR APPROVAL  OF  THE
MERGER  AGREEMENT, FOR APPROVAL OF EACH OF  THE PRIMERGY PLANS, FOR THE ELECTION
OF  THE  NOMINATED  DIRECTORS,  FOR  THE  RATIFICATION  OF  THE  APPOINTMENT  OF
INDEPENDENT ACCOUNTANTS AND AGAINST EACH OF THE SHAREHOLDER PROPOSALS.

    WEC.   The WEC Board  has determined that the  terms of the proposed Mergers
are fair to, and in  the best interests of,  WEC's shareholders. At the  meeting
held  on April  28, 1995,  the WEC  Board unanimously  adopted and  approved the
Merger Agreement and the transactions contemplated thereby.

    The WEC Board believes  that the Mergers  represent a significant  strategic
opportunity  for WEC and should offer  WEC and its shareholders better prospects
for the future than would be available to

                                       40
<PAGE>
WEC as a stand-alone entity. In addition to the joint benefits described  above,
the  WEC  Board believes  that the  Mergers would  offer the  following distinct
benefits to WEC and its shareholders over the long term:

    - It is anticipated  that Primergy  will adopt NSP's  common share  dividend
      payment  level  as  of the  Effective  Time  adjusted for  the  Ratio. NSP
      currently pays $2.70 per share annually  and, based on the Ratio, the  pro
      forma  dividend rate for Primergy would  be $1.66 per share. WEC's current
      annual dividend rate is $1.47 per share. Thus the Primergy dividend  would
      represent  a  13%  increase in  the  dividend  per share  for  current WEC
      shareholders. While the  dividend policy actually  adopted by Primergy  is
      subject  to evaluation from  time to time  by the Primergy  Board based on
      Primergy's   results   of   operations,   financial   condition,   capital
      requirements  and other relevant considerations,  the WEC Board considered
      this possible dividend increase a distinct benefit to its shareholders.

    - The potential  for  revenues  and growth  in  the  non-utility  businesses
      currently   conducted  by  NSP's   non-utility  subsidiaries  provides  an
      opportunity  for  WEC  shareholders  to  realize  the  benefits  of  these
      diversification activities.

    In reaching its decision to approve the Merger Agreement, and in addition to
the factors described above, the WEC Board considered the following factors: (i)
the  current and historical market prices and  dividends on the WEC Common Stock
and the NSP Common Stock (as disclosed under "Selected Historical and Pro  Forma
Data  -- Comparative Market Prices  and Dividends"); (ii) information concerning
the financial performance, condition, business operations and prospects of  each
of  WEC and NSP, which  indicate the compatibility of  the two companies and the
potential synergies which could  be realized as a  result of their  combination;
(iii)  the effects of the Mergers  on WEC's existing shareholders, including the
opportunity to share in  the anticipated benefits of  ownership of the  combined
enterprise;  (iv) the expected accounting treatment  of the Mergers as a pooling
of interests (as discussed  under "-- Accounting  Treatment"), which avoids  the
reduction  in earnings which would result  from the creation and amortization of
goodwill under  the purchase  method  of accounting;  (v) the  expected  federal
income tax treatment of the Mergers as a tax-free reorganization to shareholders
(as  described under  "-- Certain  Federal Income  Tax Consequences");  (vi) the
proposed structure of  the transaction as  a "merger-of-equals," which  provides
for  balanced treatment of WEC and  NSP and their respective shareholders; (vii)
the regulatory treatment  to be  requested in  connection with  the Mergers  (as
discussed  under "Regulatory Matters");  (viii) the opinion  of Barr Devlin (see
"-- Opinions  of  Financial Advisors  --  WEC's Financial  Advisor");  (ix)  the
projected  pro forma ownership of Primergy by the shareholders of WEC implied by
the Ratio; and (x) the  terms of the Merger  Agreement (as described under  "The
Merger  Agreement"), the Stock  Option Agreements (as  decribed under "The Stock
Option Agreements") and the Employment Agreements with Messrs. Abdoo and  Howard
(as  described  under "--  Employment  Agreements" and  "Primergy  Following the
Mergers -- Management of Primergy"), which provide for an orderly integration of
and transition in management after the Effective Time. The WEC Board  considered
the above factors as a whole, and did not assign specific or relative weights to
such factors.

    THE  WEC BOARD HAS UNANIMOUSLY ADOPTED AND APPROVED THE MERGER AGREEMENT AND
BELIEVES THAT THE TERMS OF  THE MERGERS ARE FAIR TO,  AND IN THE BEST  INTERESTS
OF,  WEC'S SHAREHOLDERS AND HAS APPROVED EACH OF THE WEC ARTICLES AMENDMENTS AND
EACH OF THE PRIMERGY PLANS. THE WEC BOARD RECOMMENDS A VOTE FOR APPROVAL OF  THE
MERGER  AGREEMENT, FOR APPROVAL OF  EACH OF THE WEC  ARTICLES AMENDMENTS AND FOR
APPROVAL OF EACH OF THE PRIMERGY PLANS.

OPINIONS OF FINANCIAL ADVISORS

    NSP'S FINANCIAL ADVISOR.   On April  28, 1995, Goldman  Sachs delivered  its
oral  opinion to the NSP Board  that, as of the date  of such opinion, the Ratio
pursuant to the Merger Agreement was fair to the holders of shares of NSP Common
Stock. Goldman Sachs subsequently confirmed its  April 28, 1995 oral opinion  by
delivery of its written opinion dated as of the date hereof.

                                       41

    THE  FULL TEXT OF THE WRITTEN OPINION OF  GOLDMAN SACHS DATED AS OF THE DATE
OF THIS JOINT PROXY  STATEMENT/ PROSPECTUS, WHICH  SETS FORTH ASSUMPTIONS  MADE,
MATTERS  CONSIDERED AND LIMITS  OF THE REVIEW UNDERTAKEN  IN CONNECTION WITH THE
OPINION, IS ATTACHED HERETO AS ANNEX F AND IS INCORPORATED HEREIN BY  REFERENCE.
HOLDERS  OF  SHARES OF  NSP COMMON  STOCK ARE  URGED TO,  AND SHOULD,  READ SUCH
OPINION IN ITS ENTIRETY.

    In connection with its opinion, Goldman Sachs reviewed, among other  things,
the  Merger Agreement;  the Joint  Registration Statement,  including this Joint
Proxy Statement/Prospectus relating to the NSP and WEC Meetings; Annual  Reports
to  shareholders and  Annual Reports on  Form 10-K of  NSP and WEC  for the five
years ended  December 31,  1994;  certain interim  reports to  shareholders  and
Quarterly  Reports on Form  10-Q of NSP  and WEC; FERC  Forms 1 of  NSP and WEC;
certain other communications from NSP and WEC to their respective  shareholders;
and  certain internal financial analyses and  forecasts for NSP and WEC prepared
by their respective  managements, including  analyses and  forecasts of  certain
operating  efficiencies and  financial synergies  expected to  be achieved  as a
result of the Mergers. Goldman Sachs  also held discussions with members of  the
senior  management  of  NSP and  WEC  regarding  the past  and  current business
operations,  financial  condition  and  future  prospects  of  their  respective
companies  and  their  analyses  of  the  strategic  benefits  of  the  Mergers,
including, without  limitation, the  amount  and timing  of realization  of  the
synergies  referred to above.  In addition, Goldman  Sachs reviewed the reported
price and trading activity for the shares of NSP Common Stock and the WEC Common
Stock, compared certain financial and stock  market information for NSP and  WEC
with similar information for certain other companies the securities of which are
publicly  traded,  reviewed  the  financial  terms  of  certain  recent business
combinations  in  the  electric  utility  industry  specifically  and  in  other
industries  generally and performed  such other studies  and analyses as Goldman
Sachs considered appropriate.

    Goldman Sachs relied,  without independent verification,  upon the  accuracy
and  completeness of all of  the financial and other  information reviewed by it
for purposes of its opinion, including certain synergies expected to be achieved
in the  Mergers.  In  addition,  Goldman  Sachs  has  not  made  an  independent
evaluation  or appraisal of the  assets and liabilities of NSP  or WEC or any of
their respective subsidiaries and Goldman Sachs has not been furnished with  any
such  evaluation or appraisal.  Goldman Sachs assumed,  with NSP's consent, that
the consummation of the transactions  contemplated by the Merger Agreement  will
be  accounted for as a pooling  of interests under generally accepted accounting
principles. In arriving at its opinion,  Goldman Sachs assumed that the  Mergers
will  be reorganizations  as described  in Section 368(a)  of the  Code, and the
regulations thereunder,  and that  WEC,  NSP and  the  shareholders of  NSP  who
exchange  their shares solely  for stock of  Primergy will recognize  no gain or
loss for federal  income tax purposes  as a  result of the  consummation of  the
Mergers.

    The  following  is a  summary  of the  material  financial analyses  used by
Goldman Sachs in connection with providing its oral opinion to the NSP Board  on
April  28, 1995. Goldman Sachs utilized substantially the same type of financial
analyses in connection  with providing  the written opinion  attached hereto  as
Annex F.

        (i)   SELECTED COMPANIES ANALYSIS.   Goldman Sachs reviewed and compared
    certain actual and estimated financial  information relating to NSP and  WEC
    to  corresponding financial information, ratios  and public market multiples
    for nine  publicly traded  corporations:  American Electric  Power  Company,
    Inc.,  Baltimore Gas & Electric Company,  CINergy Corp., Duke Power Company,
    LG&E Energy Corp., PacifiCorp, Union Electric Co., Utilicorp United Inc. and
    WPL Holdings  Inc. (collectively,  the "Selected  Companies"). The  Selected
    Companies  were  chosen  because  they  are  publicly-traded  companies with
    operations that for purposes  of analysis may be  considered similar to  NSP
    and  WEC. Goldman Sachs calculated  and compared various financial multiples
    and ratios. The multiples of  NSP and WEC were  calculated using a price  of
    $44.00  per share of NSP Common Stock and a price of $27.63 per share of WEC
    Common Stock, the  respective closing  prices of  the shares  of NSP  Common
    Stock  and WEC Common Stock on the NYSE on April 20, 1995. The multiples and
    ratios for NSP and WEC and the multiples for each of the Selected  Companies
    were  based on  closing market prices  on April 20,  1995, publicly reported

                                       42
<PAGE>
    financial results  and publicly  available  information from  Goldman  Sachs
    Investment  Research Estimates.  Goldman Sachs  considered for  the Selected
    Companies estimated 1995  price/earnings ("P/E") ratios,  which ranged  from
    11.0x  to 12.9x compared to 12.6x for  NSP and 12.9x for WEC; dividend yield
    and payout percentages, which ranged  from 5.0% to 7.5%  and 62% to 83%  for
    the   Selected   Companies,  respectively,   compared   to  6.0%   and  75%,
    respectively, for NSP and 5.1% and  66%, respectively, for WEC; a  five-year
    projected  earnings per share  ("EPS") and dividend  per share growth rates,
    which were provided from Goldman Sachs Investment Research and which  ranged
    from 2.0% to 3.5% and 1.0% to 3.5% for the Selected Companies, respectively,
    compared  to  2.5%  and  2.0%,  respectively, for  NSP  and  2.5%  and 2.0%,
    respectively, for  WEC. Goldman  Sachs also  considered market  values as  a
    multiple  of book value and cash flows (which were computed by adding to net
    income after  preferred  dividends,  depreciation accruals  and  income  tax
    deferrals  and deducting any  funds used during  construction, deferred fuel
    expenses and  accrued revenues).  Goldman Sachs'  analyses of  the  Selected
    Companies indicated multiples of book value which ranged from 1.28x to 1.77x
    compared  to multiples of  1.55x for NSP  and 1.75x for  WEC. Goldman Sachs'
    analyses of the Selected  Companies also indicated  multiples of cash  flows
    which  ranged from 4.45x to  8.94x compared to multiples  of 5.98x and 6.66x
    for NSP and WEC, respectively.

        (ii)   PRO FORMA  MERGER ANALYSIS.   Goldman  Sachs prepared  pro  forma
    analyses  of the financial impact of the Mergers on holders of shares of NSP
    Common Stock. Using net  income estimates for WEC  and net income  estimates
    for  NSP prepared by their respective  managements for the years 1995, 1996,
    1997, 1998 and 1999, Goldman Sachs compared the EPS of NSP Common Stock,  on
    a  stand-alone basis, to the EPS of the Primergy Common Stock on a pro forma
    basis. Goldman Sachs performed this  analysis based on certain  assumptions,
    financial  forecasts and synergies expected to be achieved in respect of the
    Mergers. Based on such analysis, the proposed transaction would be accretive
    to NSP's shareholders on an  EPS basis in the years  1997, 1998 and 1999  at
    levels of 8.6%, 13.3% and 15.5%, respectively.

        (iii)  CONTRIBUTION ANALYSIS.  Goldman Sachs reviewed certain historical
    and  estimated future operating and  financial information (including, among
    other things, market capitalization, net income and book value) for NSP, WEC
    and Primergy resulting from  the Mergers based on  NSP and WEC  managements'
    consensus  financial  forecasts  for  each  of  NSP  and  WEC.  The analysis
    indicated that NSP would contribute 49% of the market capitalization and 52%
    of the book  value of  Primergy. Goldman  Sachs also  analyzed the  relative
    income  statement contributions of  NSP and WEC  to Primergy on  a pro forma
    basis based on  actual 1994, and  estimated years 1995  and 1996,  financial
    data  provided to  Goldman Sachs by  NSP and WEC  managements. This analysis
    indicated that on a pro forma basis  in 1994 NSP would have contributed  52%
    of  the net income of Primergy and on a pro forma basis in 1995 and 1996 NSP
    would contribute 50% and  51% of the net  income of Primergy,  respectively.
    The  analysis also indicated  a range of implied  NSP/WEC exchange ratios of
    1.59x to 2.20x.

        (iv)   HISTORICAL  EXCHANGE  RATIO.    Goldman  Sachs  reviewed  certain
    historical  trading prices for the shares of NSP Common Stock and the shares
    of WEC Common Stock over the latest four years. Such analysis demonstrated a
    range of exchange ratios (calculated by dividing the price per share of  NSP
    Common Stock by the per share price of WEC Common Stock) from 1.59x to 1.69x
    and  an exchange ratio of  1.59x as of April 20,  1995 (based on the closing
    per share prices  of $44.00 per  share of  NSP Common Stock  and $27.63  per
    share of WEC Common Stock on April 20, 1995).

        (v)   DISCOUNTED CASH FLOW ANALYSIS.  Goldman Sachs performed discounted
    cash flow analyses using NSP's  management projections and WEC's  management
    projections. Goldman Sachs calculated a net present value of free cash flows
    for NSP and WEC for the years 1995 through 1999 using discount rates ranging
    from 11% to 14%. Goldman Sachs calculated NSP's and WEC's terminal values in
    the  year 1999 based on a multiple of 12x estimated free cash flows in 1999.
    These terminal values were then  discounted to present value using  discount
    rates  from 11%  to 14%. Using  NSP's and  WEC's terminal values  based on a
    multiple of 12x their respective

                                       43
<PAGE>
    estimated free cash flows  in 1999 and discounting  such terminal values  to
    present  value using discount rates ranging from 11% to 14%, the implied per
    share values ranged from $44.62 to $50.34  for NSP and $33.06 to $37.25  for
    WEC.

        (vi)   DIVIDEND DISCOUNT VALUATION ANALYSIS.   Goldman Sachs performed a
    dividend discount valuation analysis for  NSP and WEC. Using estimated  1995
    dividends  of $2.69 per share for NSP and $1.45 per share for WEC, estimated
    dividend growth rates ranging from 2% to 7% and estimated required return on
    equity rates ranging from  9% to 13%, the  implied share values ranged  from
    $24.41 to $134.25 for NSP and $13.18 to $72.50 for WEC.

    Goldman  Sachs has  stated to NSP  that, in  its view, the  preparation of a
fairness opinion is  a complex  process and  is not  necessarily susceptible  to
partial  analysis or summary description. In addition, Goldman Sachs has advised
NSP that selecting portions of the analyses  or of the summary set forth  above,
without  considering the analyses as a whole, could create an incomplete view of
the processes underlying  Goldman Sachs'  opinion. In arriving  at its  fairness
determination,  Goldman Sachs considered the results of all such analyses, taken
as a whole. Furthermore, in arriving at its fairness opinion, Goldman Sachs  did
not  attribute any particular weight to any analysis or factor considered by it;
rather, Goldman Sachs  made its  determination as to  fairness on  the basis  of
qualitative  judgments as to the significance and relevance of the financial and
comparative analyses and factors described above,  taken as a whole. No  company
or transaction used in the above analyses as a comparison is identical to NSP or
WEC  or  the contemplated  transaction. The  analyses  were prepared  solely for
purposes of Goldman  Sachs' providing its  opinion to  the NSP Board  as to  the
fairness  of the Ratio to the  holders of shares of NSP  Common Stock and do not
purport to be appraisals or necessarily  reflect the prices at which  businesses
or  securities actually  may be  sold. Analyses  based upon  forecasts of future
results are not necessarily  indicative of actual future  results, which may  be
significantly  more or less  favorable than suggested  by such analyses. Because
such analyses are inherently subject  to uncertainty, being based upon  numerous
factors  or  events  beyond  the  control of  the  parties  or  their respective
advisors,  none  of  NSP,  WEC,  Goldman  Sachs  or  any  other  person  assumes
responsibility  if future results are  materially different from those forecast.
As described above,  Goldman Sachs' opinion  to the  NSP Board was  one of  many
factors taken into consideration by the NSP Board in making its determination to
approve  the Merger Agreement. Although Goldman  Sachs evaluated the fairness of
the Ratio to the holders of shares  of NSP Common Stock, the specific Ratio  was
determined  by  WEC  and  NSP through  arm's-length  negotiation.  The foregoing
summary does not purport to be a complete description of the analysis  performed
by Goldman Sachs and is qualified by reference to the written opinion of Goldman
Sachs set forth in Annex F hereto.

    Pursuant  to a letter  agreement dated January 10,  1995 (the "Goldman Sachs
Engagement Letter"), NSP engaged Goldman Sachs  to act as its financial  advisor
in  connection with  the Mergers.  Pursuant to  the terms  of the  Goldman Sachs
Engagement Letter, NSP has paid Goldman Sachs an initial fee of $250,000,  which
amount  will be  credited against  the Transaction  Fee (as  defined herein). In
addition, NSP has agreed to pay Goldman Sachs a transaction fee of 0.27% of  the
aggregate value of the market capitalization of WEC calculated using the average
of  the last sales prices of  WEC Common Stock on each  of the five trading days
prior to the  public announcement  of the transaction  (the "Transaction  Fee"),
which  Transaction Fee amounts to approximately $8,100,000. This Transaction Fee
is  earned  and  payable  in  three  equal  installments,  one  each  at  public
announcement,  shareholder  approval and  Closing  (as defined  below).  NSP has
agreed to indemnify Goldman Sachs against certain liabilities, including certain
liabilities under the federal  securities laws. In  addition, the Goldman  Sachs
Engagement  Letter provides that NSP will reimburse Goldman Sachs for any sales,
use or similar taxes arising in connection with the engagement.

    Goldman Sachs was selected as  NSP financial advisor because Goldman  Sachs,
as  part  of its  investment  banking business,  is  continually engaged  in the
valuation of  businesses and  their securities  in connection  with mergers  and
acquisitions,   negotiated   underwritings,   competitive   biddings,  secondary
distributions  of  listed  and  unlisted  securities,  private  placements   and
valuations  for estate, corporate and other  purposes. Goldman Sachs is familiar
with NSP having acted as its financial

                                       44
<PAGE>
advisor  in  connection  with,  and  having  participated  in  certain  of   the
negotiations  leading to, the Merger Agreement.  Goldman Sachs also has provided
certain investment banking services to NSP  from time to time, including  acting
as  managing underwriter of  certain public offerings of  debt securities of NSP
and may provide  investment banking services  to NSP in  the future. During  the
past  two years, Goldman Sachs has earned compensation of approximately $350,000
from  NSP  with   respect  to  such   investment  banking  services   (excluding
compensation with respect to its services related to the Mergers). Goldman Sachs
also  has provided certain investment banking services to WEC from time to time,
including acting as  managing underwriter  of certain public  offerings of  debt
securities  of  WEPCO, for  which it  received  customary compensation,  and may
provide investment banking services  to WEC in the  future. During the past  two
years,  Goldman Sachs has earned compensation of approximately $350,000 from WEC
with respect to such investment banking services.

    In the ordinary course  of its business, Goldman  Sachs actively trades  the
debt  and  equity securities  of NSP,  WEC  and their  subsidiaries for  its own
account and for the accounts of  customers of Goldman Sachs. Goldman Sachs  may,
therefore, at any time hold a long or short position in such securities.

    WEC'S  FINANCIAL  ADVISOR.    On  January  12,  1995,  WEC  entered  into an
engagement letter with Barr Devlin pursuant to which Barr Devlin was retained to
act  as  WEC's  financial  advisor  in  connection  with  a  potential  business
combination  with NSP. Barr Devlin has delivered its written opinions to the WEC
Board,  dated   April   28,   1995   and  the   date   of   this   Joint   Proxy
Statement/Prospectus,  to  the effect  that,  on and  as  of the  dates  of such
opinions, and based upon assumptions made, matters considered and limits of  the
review,  as  set forth  in such  opinions, the  Ratio  was and  is fair,  from a
financial point of  view, to  the holders  of WEC Common  Stock. A  COPY OF  THE
OPINION  OF BARR DEVLIN  DATED THE DATE  HEREOF IS ATTACHED  TO THIS JOINT PROXY
STATEMENT/PROSPECTUS AS ANNEX  G AND  IS INCORPORATED HEREIN  BY REFERENCE.  THE
APRIL  28,  1995  OPINION IS  SUBSTANTIALLY  IDENTICAL TO  THE  OPINION ATTACHED
HERETO. WEC SHAREHOLDERS ARE URGED TO CAREFULLY READ THE OPINION DATED THE  DATE
HEREOF  IN ITS ENTIRETY FOR ASSUMPTIONS  MADE, MATTERS CONSIDERED AND THE LIMITS
OF THE REVIEW UNDERTAKEN  BY BARR DEVLIN. THE  SUMMARY OF BARR DEVLIN'S  OPINION
SET  FORTH IN THIS JOINT PROXY STATEMENT/PROSPECTUS IS QUALIFIED IN ITS ENTIRETY
BY REFERENCE TO THE ATTACHED OPINION.

    In connection with rendering its opinion dated the date of this Joint  Proxy
Statement/Prospectus,  Barr Devlin (i)  reviewed the Annual  Reports, Form 10-Ks
and the related financial  information for the three  years in the period  ended
December  31,  1994, and  the  Form 10-Qs  and  the related  unaudited financial
information for the quarterly  periods ended March 31,  1995 and June 30,  1995,
for  WEC, WEPCO  and Wisconsin Natural;  (ii) reviewed the  Annual Reports, Form
10-Ks and the related  financial information for the  three years in the  period
ended  December 31, 1994, and the Form 10-Qs and the related unaudited financial
information for the quarterly  periods ended March 31,  1995 and June 30,  1995,
for NSP and NSP-Wisconsin; (iii) reviewed certain other filings with the SEC and
other  regulatory authorities  made by  WEC, WEPCO,  Wisconsin Natural,  NSP and
NSP-Wisconsin,  including  proxy  statements,  FERC  Form  1s,  Form  8-Ks   and
registration  statements,  during the  last three  years; (iv)  reviewed certain
internal information, including financial  forecasts, relating to the  business,
earnings,  capital expenditures, cash flow, assets  and prospects of WEC and NSP
furnished to Barr Devlin by WEC and NSP; (v) conducted discussions with  members
of  senior management  of WEC  and NSP  concerning their  respective businesses,
regulatory  environments,  prospects  and  strategic  objectives  and   possible
operating,  administrative and capital synergies which might be realized for the
benefit of Primergy following the  Effective Time; (vi) reviewed the  historical
market prices and trading activity for shares of WEC Common Stock and NSP Common
Stock,  and compared them with those of certain publicly traded companies deemed
by Barr Devlin to be relevant; (vii)  compared the results of operations of  WEC
and  NSP with those of  certain companies deemed by  Barr Devlin to be relevant;
(viii) compared the proposed financial terms  of the Mergers with the  financial
terms of certain utility industry business combinations deemed by Barr Devlin to
be  relevant; (ix)  analyzed the  respective contributions  in terms  of assets,
earnings, cash flow  and shareholders' equity  of WEC and  NSP to Primergy;  (x)
analyzed   the  valuation  of  shares  of   WEC  Common  Stock  and  NSP  Common

                                       45
<PAGE>
Stock using  various  valuation  methodologies  deemed  by  Barr  Devlin  to  be
appropriate;  (xi) considered the pro forma  effect of the Mergers on Primergy's
capitalization, earnings and cash flow; (xii)  compared the pro forma effect  of
the  Mergers on WEC's  capitalization ratios, earnings  per share, dividends per
share, book value per share,  cash flow per share,  return on equity and  payout
ratio  with  each  of their  corresponding  current  and projected  values  on a
stand-alone basis; (xiii) considered the obligation of Primergy to register as a
public utility holding company under the 1935 Act and the resulting  possibility
that  Primergy would be required to dispose of WEC's and/or NSP's gas operations
or to dispose  of certain of  WEC's and/or NSP's  non-utility businesses;  (xiv)
examined  the  possible  tax  treatment  of  alternative  ways  of  effecting  a
disposition of certain of WEC's and/or  NSP's gas operations, and a  disposition
of  WEC's and/or  NSP's non-utility  businesses should  any such  disposition be
required pursuant to the 1935 Act, for which Barr Devlin relied on the advice of
WEC's  counsel;  (xv)  reviewed  the  Merger  Agreement  and  the  Stock  Option
Agreements;  (xvi)  reviewed the  Joint  Registration Statement,  including this
Joint Proxy  Statement/Prospectus;  and  (xvii)  reviewed  such  other  studies,
conducted  such other  analyses, considered  such other  financial, economic and
market criteria, performed such other investigations and took into account  such
other matters as Barr Devlin deemed necessary or appropriate for purposes of its
opinion.

    In   preparing  its  opinions,  Barr   Devlin  relied,  without  independent
verification, on  the  accuracy and  completeness  of all  financial  and  other
information publicly available or otherwise furnished or made available to it by
WEC and NSP, and further relied upon the assurances of management of WEC and NSP
that  they  were  not  aware  of any  facts  that  would  make  such information
inaccurate or misleading. With respect to  the financial projections of WEC  and
NSP  (including,  without  limitation,  projected  cost  savings  and  operating
synergies), Barr Devlin relied upon assurances of management of WEC and NSP that
such projections  were  reasonably prepared  and  reflected the  best  currently
available  estimates and judgments  of the management  of WEC and  NSP as to the
future financial performance of WEC and NSP, as  the case may be, and as to  the
outcomes projected of legal, regulatory and other contingencies. Barr Devlin was
not  provided with and did not  undertake an independent evaluation or appraisal
of the assets or liabilities  (contingent or otherwise) of  WEC or NSP, nor  did
Barr  Devlin make any physical inspection of  the properties or assets of WEC or
NSP.

    In arriving at its  opinions, Barr Devlin assumed  that the Mergers will  be
reorganizations  as described in Section 368(a) of the Code, and the regulations
thereunder, and that  WEC, NSP and  the shareholders of  NSP who exchange  their
shares  solely for stock of Primergy will  recognize no gain or loss for federal
income tax purposes as a result of the consummation of the Mergers. In addition,
Barr Devlin has assumed that the Mergers will qualify as a pooling of  interests
for financial accounting purposes. Barr Devlin's opinions are based upon general
financial,  stock market and other conditions  and circumstances as they existed
and could be  evaluated, and the  information made  available to it,  as of  the
respective  dates of the  opinions. Barr Devlin's opinions  are directed only to
the WEC Board and the fairness of the  Ratio from a financial point of view,  do
not   address  any  other  aspect  of  the  Mergers  and  do  not  constitute  a
recommendation to any WEC shareholder as to how such shareholder should vote  at
the WEC Meeting. Although Barr Devlin evaluated the fairness of the Ratio from a
financial  point of view to the holders  of WEC Common Stock, the specific Ratio
was determined by  WEC and  NSP through  arm's-length negotiation.  WEC did  not
place  any limitations upon Barr Devlin  with respect to the procedures followed
or factors considered by Barr Devlin in rendering its opinions.

    Barr Devlin has advised WEC that, in its view, the preparation of a fairness
opinion involves various determinations as to the most appropriate and  relevant
methods  of  financial analysis  and  the application  of  those methods  to the
particular  circumstances  and,  therefore,  such  an  opinion  is  not  readily
susceptible  to summary  description. Furthermore,  in arriving  at its fairness
opinions, Barr Devlin did not attribute any particular weight to any analysis or
factor considered by it, nor  did Barr Devlin ascribe  a specific range of  fair
values  to WEC; rather, Barr Devlin made its determination as to the fairness of
the Ratio  on the  basis of  qualitative judgments  as to  the significance  and
relevance  of  each  of  the  financial  and  comparative  analyses  and factors
described below. Accordingly,  notwithstanding the  separate factors  summarized
below,   Barr  Devlin  believes   that  its  analyses   must  be  considered  as

                                       46
<PAGE>
a whole and that considering  any portions of such  analyses and of the  factors
considered,  without  considering  all  analyses  and  factors,  could  create a
misleading or incomplete view of the evaluation process underlying its  opinion.
In  its analyses,  Barr Devlin  made many  assumptions with  respect to industry
performance, general business and economic conditions and other matters, many of
which are  beyond WEC's  and NSP's  control. Any  estimates contained  in  these
analyses are not necessarily indicative of actual values or predictive of future
results or values, which may be significantly more or less favorable than as set
forth  therein. In addition, analyses relating to the value of businesses do not
purport to be appraisals or to  reflect the prices at which businesses  actually
may be sold.

    In  connection with rendering its opinions dated April 28, 1995 and the date
hereof, and preparing  its various  written and  oral presentations  to the  WEC
Board, Barr Devlin performed a variety of financial and comparative analyses and
considered  a variety of factors of which  the material analyses and factors are
summarized below. The summary set forth below does not purport to be a  complete
description  of the analyses  performed or factors considered  by Barr Devlin in
this regard.  The  results  of  the analyses  described  in  this  summary  were
discussed  with the  WEC Board  at its  meeting on  April 28,  1995. Barr Devlin
derived implied exchange ratios for WEC Common Stock and NSP Common Stock  based
upon  what  these  analyses,  when  considered  in  light  of  the  judgment and
experience of Barr Devlin, suggested about their relative values. Barr  Devlin's
opinions  are based upon its consideration of the collective results of all such
analyses, together with the other factors  referred to in its opinions.  Because
each  share of WEC Common Stock will remain outstanding, unchanged, as one share
of Primergy Common Stock, these implied  exchange ratios can be compared to  the
1.626 shares of Primergy Common Stock that each share of NSP Common Stock (other
than  NSP Dissenting Shares)  will ultimately be converted  into pursuant to the
Mergers. In concluding that the Ratio is  fair, from a financial point of  view,
to  the holders of WEC  Common Stock and in its  discussions with the WEC Board,
Barr Devlin noted that 1.626 was within or below each range of implied  exchange
ratios set forth below, which were derived from the analyses performed by it. In
connection with its opinion dated the date hereof, Barr Devlin performed certain
procedures  to update its analyses  made in connection with  the delivery of its
April 28, 1995  opinion and reviewed  with the  managements of WEC  and NSP  the
assumptions  upon which such  analyses were based. The  results of such analyses
were substantially the same as those arrived at in connection with the April 28,
1995 opinion of Barr Devlin.

    CONTRIBUTION ANALYSIS.  Barr Devlin calculated the relative contribution  of
WEC  and  NSP to  the pro  forma combined  Primergy, assuming  that WEC  and NSP
performed in accordance with  the operating and  financial projections of  their
respective  managements  for  the  period  1995  through  1999  (the "Projection
Period"), with respect  to (i)  net income, (ii)  book value  of common  equity,
(iii)  earnings before interest and  taxes ("EBIT") and (iv)  cash flow, in each
case for the year 1994 and for each year in the Projection Period.

    Although Barr  Devlin considered  each of  the above-mentioned  contribution
measures,  Barr Devlin  attributed relatively greater  weight to  three of these
measures (net  income, book  value of  common equity  and EBIT)  because of  its
judgment  that they are more appropriate  indicators of relative contribution to
shareholder value. The analysis of relative contribution of net income to common
stock yielded implied exchange ratios during the Projection Period ranging  from
1.55  to  1.67  with  a  midpoint  value  of  1.61.  The  analysis  of  relative
contribution of  book value  of common  equity yielded  implied exchange  ratios
during  the Projection Period ranging from 1.73 to 1.76 with a midpoint value of
1.74. The analysis  of relative  contribution of EBIT  yielded implied  exchange
ratios  during the Projection Period  ranging from 1.66 to  1.80 with a midpoint
value of 1.73. These contribution indices yielded implied exchange ratios during
the Projection Period ranging from 1.55 to 1.80 with a midpoint value of 1.68.

    STOCK TRADING HISTORY.   Barr  Devlin reviewed  the performance  of the  per
share  market price and trading volumes of WEC Common Stock and NSP Common Stock
and compared such per share market price  movements to movements in (i) the  Dow
Jones  Utility  Index and  (ii)  the Standard  &  Poor's 500  Index,  to provide
perspective on the current and historical stock price performance of WEC and NSP

                                       47
<PAGE>
relative  to the  Comparable Companies (as  defined herein)  and selected market
indices. Barr Devlin also calculated the  ratio of the per share weekly  closing
market  price of NSP to the per share weekly closing market price of WEC for the
period April 24, 1992  to April 21,  1995. This analysis  showed that over  this
three-year  period NSP Common Stock traded at a  price as high as 1.79 times, as
low as 1.50 times  and at an  average of 1.64 times  the then-current per  share
market  price of WEC Common Stock. For the six-month and 18-month periods ending
April 21, 1995, NSP Common Stock traded, respectively, at an average of 1.69 and
1.66 times the  then-current per share  market price of  WEC Common Stock.  This
analysis  was utilized to provide historical  background for the manner in which
the public trading market had valued WEC and NSP in absolute terms and  relative
to each other.

    PUBLICLY  TRADED  COMPARABLE  COMPANY ANALYSIS.    Using  publicly available
information, Barr  Devlin compared  selected  financial information  and  ratios
(described  below) for WEC and NSP  with the corresponding financial information
and ratios for a group of electric  and/or gas utilities operating in the  upper
midwestern  U.S. and a group of other selected electric utilities deemed by Barr
Devlin  to  be  comparable  to  WEC  and  NSP  (collectively,  the   "Comparable
Companies"). The upper midwestern U.S. Comparable Companies were selected on the
basis  of  being  companies  which  possessed  general  business,  operating and
financial characteristics representative of companies in industries in which WEC
and NSP operate and  whose principal geographic areas  of operation are  located
either:  (i)  in  states  in which  WEC  or  NSP have  electric  or  gas utility
operations, or (ii)  in states  contiguous to  those in  which WEC  or NSP  have
electric  or  gas  utility  operations.  The  other  Comparable  Companies  were
companies  which   possessed   general   business,   operating   and   financial
characteristics  representative of companies in industries  in which WEC and NSP
operate and whose principal geographic areas of operation are located outside of
the upper  midwestern  U.S.  The  upper  midwestern  U.S.  Comparable  Companies
included  Interstate Power  Company, Madison  Gas &  Electric Company, Minnesota
Power & Light Company, Otter Tail  Power Company, WICOR Inc., WPL Holdings  Inc.
and WPS Resources Corporation. The other Comparable Companies included Baltimore
Gas  & Electric Company,  Florida Progress Corporation,  NIPSCO Industries Inc.,
San Diego Gas & Electric Company, SCANA Corporation, Union Electric Company  and
Western Resources Inc.

    In  evaluating the current market  value of WEC Common  Stock and NSP Common
Stock, Barr Devlin determined ranges of multiples for selected financial  ratios
for  the Comparable  Companies, including: (i)  the market  value of outstanding
common stock as a multiple of (a)  net income available to common stock for  the
latest  12-month  period  ending  December  31,  1994  (the  "LTM  Period"), (b)
projected net income available  to common stock for  the 12-month period  ending
December  31,  1995, (c)  book  value of  common  equity for  the  most recently
available fiscal quarter ending December 31,  1994, and (d) after-tax cash  flow
from  operations for the 12-month period ending  December 31, 1995; and (ii) the
"aggregate market  value" (defined  as the  sum of  the market  value of  common
stock,  plus the liquidation  value of preferred stock,  the principal amount of
debt, capitalized lease obligations and minority interests, minus cash and  cash
equivalents)   as  a  multiple  of  (a)  earnings  before  interest,  taxes  and
depreciation ("EBITDA") for the LTM Period and (b) EBIT for the LTM Period. This
analysis produced reference values of $24.91 to $29.02 per share, in the case of
WEC, and $43.85 to $53.14  per share, in the case  of NSP. The implied range  of
exchange  ratios resulting from these  reference values was 1.51  to 2.13 with a
midpoint value of 1.82.

    Barr Devlin  also  evaluated  the  projected  market  values  of  shares  of
outstanding  WEC Common  Stock for  NSP Common Stock  on: (i)  December 31, 1995
based on  selected ranges  of multiples  for the  Comparable Companies  and  (a)
projected 1995 and 1996 net income available to common stock, (b) projected book
value  of common stock as of year-end 1995, and (c) projected dividend yields as
of year-end  1995;  and (ii)  December  31, 1996  based  on selected  ranges  of
multiples  for  the Comparable  Companies and  (a) projected  1996 and  1997 net
income available to common stock, (b) projected book value of common stock as of
year-end 1996, and (c)  projected dividend yields as  of year-end 1996. For  the
year ending December 31, 1995, this analysis produced reference values of $25.99
to  $29.47 per share, in the case of WEC, and $43.26 to $48.97 per share, in the
case of NSP. The implied range of exchange ratios resulting from these reference
values   was    1.47   to    1.88    with   a    midpoint   value    of    1.68.

                                       48
<PAGE>
For  the year ending December 31,  1996, this analysis produced reference values
of $27.27 to $30.91 per share in the case of WEC and $45.30 to $51.27 per  share
in  the case of NSP.  The implied range of  exchange ratios resulting from these
reference values was 1.47 to 1.88 with a midpoint value of 1.67.

    COMPARABLE TRANSACTION ANALYSIS.  In order to determine an implied  exchange
ratio based upon a comparable transaction analysis, Barr Devlin reviewed certain
transactions  involving mergers between regulated  electric utilities or holding
companies for regulated electric utilities (the "Comparable Transactions").  The
Comparable   Transactions  were  selected  on   the  basis  of  being  strategic
combinations of electric or electric and gas utility companies (or their holding
companies) which  resulted  in the  creation  of  a newly  formed,  newly  named
publicly  traded  corporation,  the board  of  directors of  which  consisted of
representatives from the boards  of directors of each  of the merging  companies
prior to the transaction.

    Barr  Devlin calculated  the implied  equity consideration  for each  of the
Comparable Transactions  as  a  multiple of  each  company's  respective  latest
12-month  net income available  to common stock, latest  12-month cash flow, and
book value  of common  equity for  the most  recently available  fiscal  quarter
preceding  such transaction.  In addition,  Barr Devlin  calculated the "implied
total consideration" (defined  as the  sum of the  implied equity  consideration
plus  the liquidation value of preferred stock and the principal amount of debt,
minus cash and  option proceeds) for  each of the  Comparable Transactions as  a
multiple  of  each company's  respective latest  12-month  EBITDA and  EBIT. The
Comparable Transactions included in this analysis consisted of Midwest Resources
Inc./Iowa-Illinois Gas & Electric Company, Washington Water Power Company/Sierra
Pacific Resources,  Cincinnati Gas  &  Electric Company/PSI  Resources,  Midwest
Energy Company/Iowa Resources and Cleveland Electric Illuminating Company/Toledo
Edison  Company. This analysis produced reference values of $23.53 to $32.90 per
share in the case of WEC and $42.36 to $55.00 per share in the case of NSP.  The
implied  range of exchange ratios resulting from these reference values was 1.29
to 2.34 with a midpoint value of 1.81.

    Because the reasons for and circumstances surrounding each of the Comparable
Transactions analyzed  were  diverse and  because  of the  inherent  differences
between  the operations of  WEC, NSP and  the companies engaged  in the selected
transactions,  Barr  Devlin  believed  that  a  purely  quantitative  comparable
transaction  analysis would not be particularly meaningful in the context of the
Mergers.  Barr  Devlin  believed  that  an  appropriate  use  of  a   comparable
transaction  analysis  in  this  instance  would  involve  qualitative judgments
concerning differences between the characteristics of these transactions and the
Mergers which would affect the relative values of the merged companies and WEC.

    DISCOUNTED CASH FLOW ANALYSIS.   In order to  determine an implied  exchange
ratio  based upon a discounted cash  flow ("DCF") analysis, Barr Devlin prepared
and reviewed the results of  unleveraged DCF analyses for  both WEC and NSP  for
the  Projection Period.  The purpose  of the DCF  analysis was  to determine the
present value  of each  of WEC  and NSP.  To calculate  the present  value of  a
business  using a  DCF analysis, the  projected unleveraged free  cash flows for
each year, together with the estimated value  of the business in the final  year
of  the Projection Period, are discounted  to the present. Barr Devlin estimated
terminal values for WEC and NSP  by applying multiples (described below) to  (i)
the  projected book value of WEC's and NSP's common equity as of the end of 1999
and (ii) the projected net income of WEC and NSP for 1999. The multiples applied
were based  on  analyses  of  the  corresponding  multiples  of  certain  public
companies  comparable to WEC  and NSP. For  the purposes of  these analyses, the
terminal multiple ranges used  were 1.45x-1.70x with respect  to book value  and
12.0x-13.5x  with  respect to  net income.  The cash  flow streams  and terminal
values were then discounted to present value using discount rates (based on  the
weighted  average costs  of capital  of 9.67%  for WEC  and 9.76%  for NSP) that
ranged from 9.0% to 10.0% for both WEC and NSP. This analysis produced reference
values of $22.71 to $29.80  per share in the case  of WEC, and $35.83 to  $47.58
per  share in the  case of NSP.  The implied range  of exchange ratios resulting
from these reference values was 1.20 to 2.10 with a midpoint value of 1.65.

                                       49
<PAGE>
    DISCOUNTED DIVIDEND ANALYSIS.  Barr Devlin prepared and reviewed the results
of discounted  dividend analyses  of  WEC and  NSP  based on  certain  financial
assumptions  relating  to projected  dividends per  share for  each year  in the
Projection Period  prepared by  WEC's and  NSP's managements.  To calculate  the
value  of a stock using discounted dividend analysis, the projected dividend per
share for  each  year  together with  the  estimated  share price  in  1999  are
discounted  to the  present at  an estimated cost  of equity  capital rate. Barr
Devlin estimated the 1999 share price  by dividing (x) the estimated  annualized
year-end  dividend in 1999 by (y) the estimated cost of equity capital rate less
the estimated sustainable rate of  growth in the respective company's  dividends
after 1999.

    Barr  Devlin considered cost  of equity capital rates  ranging from 10.0% to
11.0% and sustainable dividend  growth rates ranging from  5.0% to 6.0% for  WEC
and  cost of equity  capital rates ranging  from 10.0% to  11.0% and sustainable
dividend growth rates ranging from 4.0% to 5.0% for NSP. This analysis  produced
reference values of $23.36 to $33.40 per share in the case of WEC, and $36.12 to
$48.08  per  share in  the case  of NSP.  The implied  range of  exchange ratios
resulting from these reference values was 1.08 to 2.06 with a midpoint value  of
1.57.

    PRO  FORMA MERGER ANALYSIS.  Barr  Devlin analyzed certain pro forma effects
to the shareholders of WEC resulting from  the Mergers, based on the Ratio,  for
each  year  in the  Projection Period.  This analysis,  based on  the respective
forecasts of the managements of WEC and NSP and assuming retention of a  portion
of  the  synergies  forecasted (assuming  the  regulatory plan  was  approved as
contemplated) showed meaningful accretion to  WEC shareholders in dividends  per
share and moderate accretion in earnings per share.

    Barr  Devlin was selected as WEC's financial advisor because Barr Devlin and
principals of Barr Devlin have a  long history of association in the  investment
banking and electric and gas utility industries. Barr Devlin is a privately-held
investment  banking firm specializing in  strategic and merger advisory services
to the electric  and gas utility  industries, the energy  industry and  selected
other  industries. In this  capacity, Barr Devlin and  principals of Barr Devlin
have been involved as advisors in numerous transactions and advisory assignments
in the electric,  gas and energy  industries and are  constantly engaged in  the
valuation of businesses and securities within such industries.

    Pursuant  to the terms  of Barr Devlin's  engagement, WEC has  agreed to pay
Barr Devlin for  its services  in connection with  the Mergers  (i) a  financial
advisory  retainer fee of  $50,000 per quarter  (which is the  same retainer fee
required by a  1993 letter  agreement between WEC  and Barr  Devlin for  ongoing
financial  advisory  services; quarterly  payment  under such  earlier agreement
constitutes payment of the quarterly retainer  fee due for services rendered  in
connection with the Mergers); (ii) an initial financial advisory progress fee of
$1,500,000  payable upon execution of the  Merger Agreement; (iii) an additional
financial advisory  progress  fee of  $1,500,000  payable upon  WEC  shareholder
approval  of the Merger  Agreement and the  WEC Articles Amendment;  (iv) if the
Mergers are consummated, a transaction fee based on the aggregate  consideration
(I.E.,  the fair market value  at the Closing Date  of the Primergy Common Stock
issued pursuant  to the  Merger Agreement)  to be  paid in  connection with  the
Mergers,  ranging from 0.45%  of the aggregate  consideration (for a transaction
with an aggregate  consideration of  $1,000,000,000) to 0.35%  of the  aggregate
consideration   (for   a  transaction   with   an  aggregate   consideration  of
$4,000,000,000); and (v) if  WEC were to receive  a termination fee pursuant  to
the  Merger Agreement and/or the NSP Stock Option Agreement, a breakup fee in an
amount which is equal to 20% of the  excess of the aggregate amount of all  such
termination  fees  over the  direct out-of-pocket  expenses  incurred by  WEC in
connection with the Mergers. If the Merger  had been consummated as of the  date
of  this Joint Proxy  Statement/Prospectus, the transaction  fee payable to Barr
Devlin would  have been  approximately $11,600,000.  All retainer  fees  payable
during  the term of the engagement, all  financial advisory progress fees and an
additional $750,000 would  be credited  against any transaction  fee payable  to
Barr  Devlin. If  a transaction fee  is paid by  WEC, Barr Devlin  has agreed to
waive its  rights  to  the  four  subsequent  quarterly  retainer  fee  payments
otherwise  payable pursuant to the 1993 letter agreement following the date such
transaction fee becomes payable. WEC has agreed to reimburse Barr Devlin for its
out-of-pocket expenses, including fees and  expenses of legal counsel and  other
advisors engaged with the

                                       50
<PAGE>
consent  of  WEC,  and to  indemnify  Barr Devlin  against  certain liabilities,
including liabilities under the federal securities laws, relating to or  arising
out of its engagement. In connection with Barr Devlin's engagement, WEC has also
agreed  to consider  Barr Devlin as  one of  the potential candidates  to act as
WEC's financial advisor in  future transactions of a  specified nature, if  any,
for  a period  of three  years following  the date  any transaction  fee becomes
payable. If Barr Devlin were to be  so engaged, the consideration to be paid  to
Barr  Devlin for any such  successful future transaction would  be at a discount
from its normal fee scale. If WEC were to engage a financial advisor other  than
Barr Devlin for such a future transaction, the discounted fee schedule would not
apply to any subsequent engagement of Barr Devlin.

    Barr  Devlin has rendered  from time to time  various investment banking and
other financial advisory services to WEC. Since January 1, 1993, Barr Devlin has
earned compensation  from WEC  with respect  to such  services of  approximately
$700,000  (excluding compensation  with respect to  its services  related to the
Mergers).

INTERESTS OF CERTAIN PERSONS IN THE MERGERS

    In considering the recommendations of the Boards of Directors of WEC and NSP
with respect to the Mergers, shareholders  should be aware that certain  members
of  WEC's and NSP's management and Boards of Directors have certain interests in
the Mergers that are in addition to the interests of shareholders of WEC and NSP
generally. The Boards of Directors  of each of WEC and  NSP were aware of  these
interests  and considered  them, among  other matters,  in approving  the Merger
Agreement and the transactions contemplated thereby.

    EMPLOYMENT AGREEMENTS.    The Employment  Agreements  with each  of  Messrs.
Howard  and  Abdoo  will  become  effective  only  at  the  Effective  Time. The
Employment  Agreement  of  Mr.  Howard  will  replace  his  existing  employment
agreement  dated February 1, 1987,  and amended as of  April 25, 1990 and August
24, 1994, with NSP.  The Employment Agreements are  described in greater  detail
under "-- Employment Agreements" below.

    EMPLOYEE  PLANS AND  SEVERANCE ARRANGEMENTS.   Under  certain benefit plans,
severance arrangements  and other  employee  agreements maintained,  or  entered
into,  by  WEC, certain  benefits may  become vested,  and certain  payments may
become payable, in connection with the Mergers, but WEC has agreed in the Merger
Agreement to use its best efforts to obtain all necessary consents to the waiver
thereof in connection with the Mergers, as described in greater detail under "--
Primergy Plans --  Actions with Respect  to Existing Stock  Options and  Certain
Other Existing Arrangements."

    BOARD  OF DIRECTORS.  As provided in  the Merger Agreement, at the Effective
Time, the Primergy Board will consist of 12 directors, comprised of six  persons
designated  by WEC,  including Richard A.  Abdoo, and six  persons designated by
NSP,  including  James  J.  Howard.  See  "Primergy  Following  the  Mergers  --
Management of Primergy."

    INDEMNIFICATION.   Pursuant to the Merger  Agreement, to the extent, if any,
not provided  by an  existing right  of indemnification  or other  agreement  or
policy,  from and after the Effective Time, Primergy will, to the fullest extent
permitted by applicable  law, indemnify,  defend and hold  harmless each  person
who, prior to the Effective Time, was an officer, director or employee of WEC or
NSP  or any  of their subsidiaries  (including New  NSP or WEC  Sub) against all
losses, expenses  (including reasonable  attorneys'  fees), claims,  damages  or
liabilities or, subject to certain restrictions, amounts paid in settlement, (i)
arising  out of actions or omissions occurring at or prior to the Effective Time
that are in whole  or in part based  on, or arising out  of, the fact that  such
person  is or was a  director, officer or employee of  such party, or (ii) based
on, arising out of or pertaining to the transactions contemplated by the  Merger
Agreement. See "The Merger Agreement -- Indemnification."

CERTAIN ARRANGEMENTS REGARDING THE DIRECTORS AND MANAGEMENT OF PRIMERGY
FOLLOWING THE MERGERS

    In  connection with the Mergers, the  Primergy Board, at the Effective Time,
will consist of 12  persons, six of whom  will be designated by  NSP and six  of
whom  will  be  designated  by  WEC.  See  "Primergy  Following  the  Mergers --
Management  of   Primergy"   for   a   description   of   the   composition   of

                                       51
<PAGE>
the  initial Primergy  Board. To  date, NSP  and WEC  have not  determined which
individuals, in addition  to Messrs.  Howard and  Abdoo, will  be designated  to
serve as directors of Primergy as of the Effective Time. In addition, the Merger
Agreement provides that during the three year period commencing at the Effective
Time,  certain  provisions thereof  (including  provisions relating  to existing
employee agreements, workforce  matters, benefit plans,  stock option and  other
plans  and certain officer positions  of Primergy) may be  enforced on behalf of
the officers, directors and employees of WEC and NSP, as the case may be, by the
directors of  Primergy  designated  by  WEC  and  NSP,  respectively  (or  their
successors).

EMPLOYMENT AGREEMENTS

    Forms  of the Employment Agreements of Messrs. Howard and Abdoo are attached
hereto as Annexes D and E, respectively. Messrs. Howard and Abdoo are  sometimes
hereinafter   individually  referred  to  as  the  "Executive."  The  Employment
Agreements will become effective only at  the Effective Time. The provisions  of
the Employment Agreements which relate to the Executive serving as a director on
the Primergy Board assume that the Executive is elected to the Primergy Board by
the Primergy shareholders.

    Pursuant to Mr. Howard's Employment Agreement, from the Effective Time until
the  later of the  date of the  annual meeting of  shareholders of Primergy that
occurs in  1998 and  the last  day of  the sixteenth  full month  following  the
Effective  Time (the  "Initial Period"), Mr.  Howard will serve  as Chairman and
Chief Executive  Officer  of  Primergy,  and thereafter  will  retire  from  the
position  of Chief Executive Officer  but will continue to  serve as Chairman of
the Board of Primergy until the later of July 1, 2000 and the second anniversary
of the  last  day of  the  Initial Period  (the  "Secondary Period").  From  the
Effective  Time until Mr. Howard ceases to serve as Chief Executive Officer, Mr.
Abdoo will serve  as Vice  Chairman, President  and Chief  Operating Officer  of
Primergy,  and thereafter  he will serve  as Vice Chairman,  President and Chief
Executive Officer. Mr. Abdoo will assume the position of Chairman at the end  of
the  Secondary Period.  Mr. Abdoo's  Employment Agreement  expires on  the fifth
anniversary of the Effective Time  or, if later, January  31, 2002, but will  be
extended  by  successive  one-year  periods  on  the  third,  fourth  and  fifth
anniversaries of the Effective Time unless either Primergy or Mr. Abdoo notifies
the other that it shall not be so extended.

    Each Employment Agreement provides that the Executive will receive an annual
base salary, short-term  and long-term incentive  compensation (including  stock
options  and restricted stock) and supplemental retirement benefits no less than
they received before the Effective Time,  as well as life insurance providing  a
death  benefit of three times their annual  base salaries. The Executive is also
entitled to  retirement  and  welfare  benefits  on  the  same  basis  as  other
executives, and certain fringe benefits.

    CERTAIN   OBLIGATIONS   OF   PRIMERGY   UPON   TERMINATION   OF   EMPLOYMENT
AGREEMENT.  If Primergy terminates the employment of the Executive without cause
(as defined  in  the Employment  Agreements)  or the  Executive  terminates  his
employment  for good reason (as defined  in the Employment Agreements), Primergy
will continue  to  provide the  compensation  and  benefits called  for  by  the
Employment  Agreement through  the end of  the term of  the Employment Agreement
(with incentive compensation based on the maximum potential awards and any stock
compensation paid  in  cash), and  all  unvested stock  compensation  will  vest
immediately and the Executive will be deemed to retire with full retiree welfare
benefits.  If  the  Executive  dies  or  becomes  disabled,  or  terminates  his
employment without good  reason, during  the term of  the Employment  Agreement,
Primergy  will  pay  to  the  Executive  or  his  beneficiaries  or  estate  all
compensation earned through the  date of death,  disability or such  termination
(including  previously deferred compensation and pro rata incentive compensation
based upon the  maximum potential  awards). If  the Executive  is terminated  by
Primergy  for  cause, Primergy  will pay  his  base salary  through the  date of
termination plus any  previously deferred  compensation. In the  event that  any
payments    to    the   Executive    under    the   Employment    Agreement   or

                                       52
<PAGE>
otherwise are subject to the excise  tax on excess parachute payments,  Primergy
will  pay an additional amount to the  Executive, such that after payment of all
income and excise taxes  on the additional amount,  the Executive will retain  a
sufficient amount to pay the excise tax.

EMPLOYEE PLANS AND SEVERANCE ARRANGEMENTS

    Effective  April 28, 1995, the respective Boards of Directors of NSP and WEC
adopted the respective  Severance Policies providing  for severance benefits  to
employees  designated as Participants. A total of 25 NSP employees (including 12
executive officers) and  25 WEC  employees (including  four executive  officers)
have  been  designated  as  Participants. The  Severance  Policies  will provide
severance benefits to Participants whose employment is terminated under  certain
circumstances  at any  time before (i)  the second anniversary  of the Effective
Time  (if  the  Mergers  are  consummated)  or  (ii)  if  the  Mergers  are  not
consummated, April 28, 2000, unless further extended by the respective Boards of
Directors.  If all participants in the Severance Policies had been terminated as
of July 1, 1996 under circumstances  giving rise to an entitlement to  severance
benefits,  the  aggregate value  of the  severance benefits  (assuming specified
increases in base salary and specified incentive compensation levels) would have
been approximately $19,000,000 for the NSP Participants (including the following
approximate amounts for  the participating  NSP executive  officers: Douglas  D.
Antony  -- $950,000; Loren L. Taylor -- $950,000; Keith H. Wietecki -- $810,000;
Arland D. Brusven -- $660,000; Jackie A. Currier -- $680,000; Gary R. Johnson --
$950,000; Cynthia  L. Lesher  --  $760,000; Edward  J. McIntyre  --  $1,040,000;
Thomas  A.  Micheletti --  $770,000;  Roger D.  Sandeen  -- $750,000;  Robert H.
Schulte  --  $770,000  and  Edward  L.  Watzl  --  $900,000)  and  approximately
$13,000,000  for  the  WEC  Participants  (including  the  following approximate
amounts for the participating WEC executive  officers: Richard R. Grigg, Jr.  --
$950,000;  David K. Porter -- $870,000;  Francis Brzezinski -- $690,000 and Anne
K. Klisurich -- $480,000).

    The Severance Policies provide for the payment of severance benefits to  any
Participant  whose employment is terminated after  April 28, 1995 and before the
second anniversary of the Effective Time (or April 28, 2000, if the Mergers  are
not  consummated), if  the Participant's  employment is  terminated: (i)  by the
employer, other than for  cause, disability or retirement;  (ii) as a result  of
the sale of a business by the employer if the purchaser of the business does not
agree  to employ  the Participant on  the same  terms and conditions  as were in
effect before the sale, including  comparable severance protection; (iii) or  by
the  Participant  within 90  days  after a  reduction in  his  or her  salary, a
material and adverse diminishment of his  or her duties and responsibilities  or
of  the program  of incentive  compensation and  employee benefits  covering the
Participant, or a relocation of the Participant by more than 50 miles.

    The severance benefits under the Severance  Policies consist of: (i) a  cash
lump  sum payment of three years' salary and annual incentive compensation; (ii)
a cash lump sum payment of the actuarial equivalent of the additional retirement
benefits the Participant would  have earned if he  or she had remained  employed
for  three  more  years;  (iii) continued  medical,  dental  and  life insurance
coverage for three years; (iv) outplacement services at a cost of not more  than
$30,000 or the use of office space and support for up to one year; (v) financial
planning   counseling  for  two  years;  and  (vi)  transfer  of  title  of  the
Participant's company  car,  if any,  at  no cost  to  the Participant.  If  the
foregoing  benefits,  when  taken  together  with  any  other  payments  to  the
Participant, result in  the imposition  of the  excise tax  on excess  parachute
payments,  then the  severance benefits  will be  reduced only  if the reduction
results in a greater after-tax payment to the Participant.

PRIMERGY PLANS

    Pursuant to the terms of the  Merger Agreement, Primergy will implement  the
Primergy  Plans described below, subject to  shareholder approval thereof at the
NSP Meeting  and  the  WEC Meeting.  Each  of  the Primergy  Plans  will  become
effective as of the Effective Time.

    PRIMERGY  STOCK  INCENTIVE  PLAN.    This  plan  is  a  comprehensive  stock
compensation plan  designed to  provide  Primergy with  the ability  to  provide
incentives  directly linked to the profitability of its businesses and increases
in shareholder  value.  Like the  WEC  1993  Omnibus Stock  Incentive  Plan  and

                                       53
<PAGE>
the  NSP Long-Term Incentive Award Stock Plan, the Primergy Stock Incentive Plan
provides for  the grant  of  stock options,  including incentive  stock  options
("ISOs"),  nonqualified  stock  options,  stock  appreciation  rights  ("SARs"),
restricted stock and performance units. The maximum number of shares of Primergy
Common Stock available for issuance under  the plan is 12,000,000, but not  more
than  3,000,000  shares  may be  issued  as restricted  stock.  The Compensation
Committee of the  Primergy Board  (the "Primergy  Compensation Committee")  will
administer the plan and make awards thereunder, and will have broad authority to
fix  the terms and  conditions of individual  agreements with participants. This
plan is being  submitted to shareholders  of WEC  and NSP for  approval, and  is
described  in greater detail under "Approval of Primergy Plans -- Primergy Stock
Incentive Plan" elsewhere in  this Joint Proxy  Statement/Prospectus; a copy  of
the  plan is attached as Annex K. Following implementation of the Primergy Stock
Incentive Plan, no further obligations will be incurred under the NSP  Long-Term
Incentive Award Stock Plan or the WEC 1993 Omnibus Stock Incentive Plan.

    PRIMERGY  MANAGEMENT INCENTIVE COMPENSATION PLAN.  This plan is a short-term
incentive compensation plan designed to  benefit eligible employees of  Primergy
and  its  subsidiaries. Like  the WEC  Short-Term Performance  Plan and  the NSP
Executive  Incentive  Compensation  Plan,  the  Primergy  Management   Incentive
Compensation  Plan  rewards  key management  personnel  for  meeting established
individual, group and corporate  goals. Employees who  participate in this  plan
will  be granted awards  payable in cash  to the extent  predetermined goals are
attained within the performance period (which will not exceed 12 months). Awards
are based on a percentage  of a participant's annual  base salary. This plan  is
being submitted to shareholders of WEC and NSP for approval, and is described in
greater  detail  under  "Approval  of  Primergy  Plans  --  Primergy  Management
Incentive Compensation Plan" elsewhere in this Joint Proxy Statement/Prospectus;
a copy of  the plan  is attached  as Annex  L. Following  implementation of  the
Primergy  Management Incentive Compensation Plan, no further obligations will be
incurred under  the  WEC  Short-Term  Performance  Plan  or  the  NSP  Executive
Incentive Compensation Plan.

    ACTIONS  WITH RESPECT TO  EXISTING STOCK OPTIONS  AND CERTAIN OTHER EXISTING
ARRANGEMENTS.   All stock  options to  acquire NSP  Common Stock  under the  NSP
Long-Term  Incentive Award Stock Plan that are outstanding at the Effective Time
will be converted into options to buy  Primergy Common Stock, and the number  of
shares  and exercise price under such options will be adjusted so as to preserve
both the same  aggregate gain or  loss immediately after  the Effective Time  as
existed  immediately before  the Effective  Time and  the ratio  of the exercise
price per share subject  to the NSP  stock option to the  fair market value  per
underlying  share. Primergy will assume the obligation to honor such options and
any other outstanding awards under the NSP Long-Term Incentive Award Stock Plan,
and the terms and  conditions of such options  and awards will otherwise  remain
the same as before the Effective Time after giving effect to the Ratio. See "The
Merger  Agreement --  Benefit Plans."  All stock  options to  acquire WEC Common
Stock and other awards under the WEC 1993 Omnibus Stock Incentive Plan that  are
outstanding  at the Effective Time will remain outstanding on the same terms and
conditions as  before the  Effective Time  and will  relate to  Primergy  Common
Stock.

    The   WEC  Supplemental   Executive  Retirement  Plan,   the  WEC  Executive
Non-Qualified Trust,  certain supplemental  retirement benefit  agreements  with
executives  of WEC  and WEC's utility  subsidiaries, the  WEC Executive Deferred
Compensation Plan, the WEC Directors'  Deferred Compensation Plan and the  WEPCO
Directors'  Deferred  Compensation  Plan all  provide  for  accelerated vesting,
funding and/or payments  upon a change  of control. The  WEC 1993 Omnibus  Stock
Incentive  Plan also provides that all  unvested options and other benefits will
vest upon a change  of control. WEC  has agreed to amend  each of the  foregoing
arrangements  so that the change of control  provisions will not be triggered by
the Mergers. However, in the  case of all such  arrangements other than the  WEC
Executive  Non-Qualified  Trust, WEC  must obtain  the  consent of  the affected
individuals, and WEC has agreed to use best efforts to obtain such consents. Mr.
Abdoo has consented to waive  all benefits that would  otherwise be paid to  him
upon    consummation   of   the   Mergers    under   the   change   of   control

                                       54
<PAGE>
provisions of those  of the above  plans in  which he participates.  All of  the
outside directors participating in the WEC Directors' Deferred Compensation Plan
have  consented  to waive  their rights  to receive  accelerated payment  of the
balances in their respective  accounts upon consummation  of the Mergers.  Other
than  Mr.  Abdoo,  no WEC  executive  officers  who participate  in  any  of the
above-referenced plans have  been approached  to obtain such  consent. Based  on
plan  account balances at December 31, 1994, the following WEC executive officer
participants in  such  plans  would  be  entitled  to  the  approximate  amounts
indicated  if they did not  waive their rights to  receive the balances in their
respective accounts  upon  consummation  of  the Mergers:  Jerry  G.  Remmel  --
$520,000;  John H. Goetsch --  $290,000; David K. Porter  -- $70,000; Richard R.
Grigg, Jr. -- $55,000; Francis Brzezinski  -- $55,000; and Anne K. Klisurich  --
$15,000.

DIVIDEND REINVESTMENT PLAN

    WEC's  Stock Plus Investment  Plan as in  effect at the  Effective Time will
continue as  the  dividend reinvestment  and  stock purchase  plan  of  Primergy
following  the  Mergers.  Participants  in  WEC's  Stock  Plus  Investment  Plan
immediately prior to  the Effective  Time will  continue to  participate in  the
Primergy dividend reinvestment and stock purchase plan after the Effective Time.
Following  the Effective Time,  former preferred and  common shareholders of NSP
will be able  to participate  in the  Primergy dividend  reinvestment and  stock
purchase plan with respect to the shares of New NSP Preferred Stock and Primergy
Common  Stock that they receive in the Mergers, and to have their accounts under
the NSP  DRIP  transferred  to  the Primergy  dividend  reinvestment  and  stock
purchase plan.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

    GENERAL.   The  following is a  summary description of  the material federal
income tax  consequences  of  the  Mergers.  This  summary  is  not  a  complete
description  of all of the  consequences of the Mergers  and, in particular, may
not address federal income tax considerations that may affect the treatment of a
shareholder that, at the Reincorporation  Effective Time or the Effective  Time,
is not a U.S. person or is a tax-exempt entity or an individual who acquired NSP
Common  Stock pursuant to an employee  stock option. In addition, no information
is provided with respect to the  tax consequences of the Mergers under  foreign,
state  or local laws.  The discussion is based  on the Code as  in effect on the
date of  this Joint  Proxy Statement/Prospectus,  without consideration  of  the
particular  facts  or  circumstances  of  any  shareholder.  CONSEQUENTLY,  EACH
SHAREHOLDER IS ADVISED TO CONSULT HIS OR HER OWN TAX ADVISOR AS TO THE  SPECIFIC
TAX CONSEQUENCES TO HIM OR HER OF THE MERGERS.

    THE  MERGERS.  Each party's obligation  to effect the Mergers is conditioned
on (i) the receipt  of a private  letter ruling from  the IRS providing  certain
assurances regarding the federal income tax consequences of the Mergers and (ii)
the  delivery of  an opinion  to NSP  from Wachtell,  Lipton, Rosen  & Katz, its
counsel, and an  opinion to WEC  from Skadden,  Arps, Slate, Meagher  & Flom  or
Quarles  & Brady,  its counsel, each  dated as  of the Closing  Date, based upon
certain customary representations and assumptions set forth therein and on  such
private  letter ruling, substantially to the effect that, for federal income tax
purposes, each of the Mergers  constitutes a tax-free reorganization within  the
meaning of Section 368(a) of the Code.

    Provided  that such a ruling is obtained (in which case, provided that there
shall have been no adverse changes in applicable law or facts at such time, such
opinions of  counsel  will  be  delivered),  the  material  federal  income  tax
consequences of the Mergers will be:

        (i)  No gain or loss will be recognized  by NSP, New NSP, WEC or WEC Sub
    pursuant to the Mergers;

        (ii) No gain  or loss  will be recognized  by holders  of NSP  Preferred
    Stock  and NSP  Common Stock  upon the  cancellation of  their NSP Preferred
    Stock and NSP  Common Stock and  conversion thereof into  New NSP  Preferred
    Stock   and   New  NSP   Common   Stock,  respectively,   pursuant   to  the
    Reincorporation Merger, but a holder of NSP Dissenting Shares that  receives
    cash  instead of stock will  recognize gain or loss  equal to the difference
    between the cash received and the

                                       55
<PAGE>
    shareholder's tax basis in the NSP  Dissenting Shares. No gain or loss  will
    be  recognized by holders of  New NSP Common Stock  upon the cancellation of
    their New NSP Common Stock and conversion thereof into Primergy Common Stock
    pursuant to the NSP  Merger, except that  a holder of  New NSP Common  Stock
    that receives cash in lieu of a fractional share interest in Primergy Common
    Stock  will recognize gain or loss equal  to the difference between the cash
    received and the tax basis allocated  to the fractional share interest.  Any
    gain  or loss  recognized by a  shareholder will constitute  capital gain or
    loss if such shareholder's NSP Preferred Stock, NSP Common Stock or New  NSP
    Common  Stock with respect to which gain or  loss is recognized is held as a
    capital asset at the Reincorporation  Effective Time or the Effective  Time,
    as the case may be;

       (iii) The tax basis of the New NSP Preferred Stock and the New NSP Common
    Stock  received by an NSP shareholder will be the same as such shareholder's
    tax basis in the NSP Preferred Stock and NSP Common Stock that was cancelled
    pursuant to the  Mergers, and  the tax basis  of the  Primergy Common  Stock
    received  by a  holder of  New NSP  Common Stock  will be  the same  as such
    shareholder's tax  basis in  the New  NSP Common  Stock that  was  cancelled
    pursuant to the Mergers reduced by the tax basis allocable to any fractional
    share  interest in Primergy Common Stock with respect to which cash is being
    received;

       (iv) The holding period of  the New NSP Preferred  Stock and the New  NSP
    Common  Stock received by an NSP  shareholder will include the shareholder's
    holding period with respect to the  NSP Preferred Stock or NSP Common  Stock
    that was cancelled pursuant to the Mergers (PROVIDED that such NSP Preferred
    Stock  or NSP  Common Stock was  held by  such NSP shareholder  as a capital
    asset at the Reincorporation Effective Time), and the holding period of  the
    Primergy  Common Stock  received by  a holder of  New NSP  Common Stock will
    include the shareholder's holding period with respect to the New NSP  Common
    Stock that was cancelled pursuant to the Mergers (provided that such New NSP
    Common  Stock was  held by such  NSP shareholder  as a capital  asset at the
    Effective Time); and

        (v) No gain or loss will be recognized by a shareholder of WEC upon  the
    Reincorporation Merger or the NSP Merger.

ACCOUNTING TREATMENT

    The Mergers are designed to qualify as a pooling of interests for accounting
and  financial reporting purposes. Under this method of accounting, the recorded
assets  and  liabilities  of  NSP  and  WEC  will  be  carried  forward  to  the
consolidated  financial statements of Primergy at their recorded amounts; income
of Primergy will include  income of NSP  and WEC for the  entire fiscal year  in
which  the Mergers occur;  and the reported income  of the separate corporations
for prior  periods will  be combined  and restated  as income  of Primergy.  The
receipt  by each of  WEC and NSP  of a letter  from their respective independent
accountants,  stating  that  the  transaction  will  qualify  as  a  pooling  of
interests,   is  a   condition  precedent   to  consummation   of  the  Mergers.
Representatives of Price Waterhouse  LLP are expected to  be present at the  NSP
Meeting  and the WEC  Meeting and to  be available to  respond to questions, and
will have an opportunity to make a statement  if they desire to do so. See  "The
Merger Agreement -- Conditions to Each Party's Obligation to Effect the Mergers"
and "Unaudited Pro Forma Combined Condensed Financial Information."

STOCK EXCHANGE LISTING OF PRIMERGY COMMON STOCK

    Application  will  be made  for the  listing on  the NYSE  of the  shares of
Primergy Common  Stock  to  be  issued  pursuant to  the  terms  of  the  Merger
Agreement.  The  listing  on the  NYSE  of  such shares,  subject  to  notice of
issuance, is a condition precedent to  the consummation of the Mergers. So  long
as  NSP and WEC continue to meet the requirements of the NYSE, NSP Common Stock,
and WEC Common Stock, as the case may be, will continue to be listed on the NYSE
until the Effective Time. So long as  NSP continues to meet the requirements  of
the  PSE and  the CSE,  the other national  securities exchanges  which list NSP
Common Stock, NSP Common Stock will continue to be listed on the PSE and the CSE
until the Effective Time.

                                       56
<PAGE>
    With respect to the  series of NSP Preferred  Stock currently listed on  the
NYSE,  New NSP will apply for listing of  such series of New NSP Preferred Stock
on the NYSE. So long as NSP continues to meet the requirements of the NYSE,  NSP
Preferred  Stock listed on the NYSE will continue to be listed on the NYSE until
the Effective Time.

FEDERAL SECURITIES LAW CONSEQUENCES

    All shares of Primergy Common Stock and New NSP Preferred Stock received  by
NSP  shareholders in the Mergers will be freely transferable, except that shares
of Primergy Common Stock and New NSP Preferred Stock received by persons who are
deemed to be "affiliates" (as such term is defined under the Securities Act)  of
NSP,  New  NSP or  WEC  prior to  the  Mergers may  be  resold by  them  only in
transactions permitted by the  resale provisions of  Rule 145 promulgated  under
the  Securities  Act  (or Rule  144,  in the  case  of such  persons  who become
affiliates of  Primergy  or  New  NSP)  or  as  otherwise  permitted  under  the
Securities  Act. Persons who may be deemed to be affiliates of NSP, New NSP, WEC
or  Primergy  generally  include  individuals  or  entities  that  control,  are
controlled  by, or  are under  common control with,  such party  and may include
certain officers and directors of such  party as well as principal  shareholders
of  such party.  The Merger Agreement  requires each of  NSP and WEC  to use all
reasonable efforts  to  cause  each  of its  affiliates  to  execute  a  written
agreement  to the effect that such affiliate will not offer or sell or otherwise
dispose of (i) any shares of NSP, WEC or Primergy during the period beginning 30
days prior  to the  Effective Time  and continuing  until such  time as  results
covering  at least  30 days of  post-Effective Time operations  of Primergy have
been published or (ii)  any of the  shares of Primergy Common  Stock or New  NSP
Preferred  Stock  issued to  such affiliate  in  or pursuant  to the  Mergers in
violation of the Securities Act or the rules and regulations promulgated by  the
SEC thereunder.

    This  Joint Proxy  Statement/Prospectus does  not cover  resales of Primergy
Common Stock or New NSP Preferred Stock received by any person who may be deemed
to be an affiliate of NSP, New NSP, WEC or Primergy.

MINNESOTA DISSENTERS' RIGHTS

    Sections 302A.471 and 302A.473 of the MBCA entitle any holder of NSP  Common
Stock  or NSP  Preferred Stock who  objects to  the Mergers and  who follows the
procedures prescribed by Section 302A.473 of the MBCA, in lieu of receiving  the
consideration  proposed under the Merger Agreement, to receive cash equal to the
"fair value" of such shareholder's shares  of NSP Common Stock or NSP  Preferred
Stock,  as the  case may  be. Set  forth below  is a  summary of  the procedures
relating to  the exercise  of such  dissenters' rights.  This summary  does  not
purport to be a complete statement of dissenters' rights and is qualified in its
entirety  by reference to Sections 302A.471 and  302A.473 of the MBCA, which are
reproduced in full as Annex M attached to this Joint Proxy  Statement/Prospectus
and  to any amendments  to such provisions as  may be adopted  after the date of
this Joint Proxy Statement/Prospectus.

    ANY NSP SHAREHOLDER  CONTEMPLATING THE  POSSIBILITY OF  DISSENTING FROM  THE
MERGERS  SHOULD CAREFULLY REVIEW THE TEXT OF ANNEX M (PARTICULARLY THE SPECIFIED
PROCEDURAL STEPS REQUIRED TO PERFECT DISSENTERS' RIGHTS, WHICH ARE COMPLEX)  AND
SHOULD  ALSO CONSULT SUCH SHAREHOLDER'S LEGAL  COUNSEL. SUCH RIGHTS WILL BE LOST
IF THE PROCEDURAL REQUIREMENTS OF SECTION 302A.473 OF THE MBCA ARE NOT FULLY AND
PRECISELY SATISFIED.

    The MBCA provides dissenters' rights for  shareholders of NSP who object  to
the Mergers and meet the requisite statutory requirements contained in the MBCA.
Under the MBCA, any NSP shareholder who (i) files with NSP written notice of his
or her intent to demand the fair value for his or her shares of NSP Common Stock
or  NSP Preferred Stock, as the case may  be, if the Mergers are consummated and
become effective, which notice is filed with NSP before the vote is taken at the
NSP Meeting and (ii) does not vote his or her shares of NSP Common Stock or  NSP
Preferred Stock, as the case may be, at the NSP Meeting in favor of the proposal
to approve the Mergers, shall be entitled, if

                                       57
<PAGE>
the  Mergers are approved  and effected, to  receive a cash  payment of the fair
value of such shareholder's  shares of NSP Common  Stock or NSP Preferred  Stock
upon compliance with the applicable statutory procedural requirements. A failure
by  any NSP shareholder to vote against the proposal to approve the Mergers will
not in and  of itself  constitute a  waiver of  the dissenter's  rights of  such
shareholder  under the MBCA.  In addition, a NSP  shareholder's vote against the
proposal to approve the Mergers will not satisfy the notice requirement referred
to in clause (i) above.

    Any written notice of a NSP shareholder's intent to demand payment for  such
shareholder's shares of NSP Common Stock or NSP Preferred Stock, as the case may
be,  if the Mergers are consummated must be filed with NSP at 414 Nicollet Mall,
Minneapolis, Minnesota 55401, Attn:  Corporate Secretary, prior  to the vote  on
the  Mergers at the  NSP Meeting. A  shareholder who votes  for the Mergers will
have no  dissenters' rights.  A shareholder  who does  not satisfy  each of  the
requirements  of Sections 302A.471 and  302A.473 of the MBCA  is not entitled to
payment for such shareholder's shares of NSP Common Stock or NSP Preferred Stock
under the dissenters' rights  provisions of the  MBCA and will  be bound by  the
terms of the Merger Agreement.

    After  the proposed Mergers have been approved  at the NSP Meeting, NSP must
send written notice to  all shareholders who have  given written notice and  not
voted  in favor of the Mergers as  described above. The notice will contain: (i)
the address where the demand for payment  and NSP Certificates must be sent  and
the  date by which they must be received  (which date will be the 30th day after
the notice is given), (ii) any restrictions on transfer of uncertificated shares
that will apply after  the demand for  payment is received, (iii)  a form to  be
used  to certify the date  on which the shareholder,  or the beneficial owner on
whose behalf the shareholder  dissents, acquired the shares  (or an interest  in
them)  and to demand payment, and (iv) a  copy of the provisions of the MBCA set
forth in Annex M with a brief description of the procedures to be followed under
those provisions. A  NSP shareholder  who is  sent a  notice and  who wishes  to
assert  dissenters' rights must demand payment and  deposit his or her NSP stock
certificates (at the  address specified in  NSP's notice) within  30 days  after
such  notice is given. Prior to the Effective Time, a NSP shareholder exercising
dissenters' rights retains all other rights of a NSP shareholder. From and after
the Effective Time, dissenting  shareholders will no longer  be entitled to  any
rights  of a shareholder,  including, but not  limited to, the  right to receive
notice of meetings, to vote  at any meetings or  to receive dividends, and  will
only be entitled to any rights of appraisal as provided by the MBCA. If any such
holder  of NSP Common Stock or NSP  Preferred Stock shall have failed to perfect
or shall have effectively withdrawn or lost such right, his or her shares of NSP
Common Stock or  NSP Preferred Stock,  as the  case may be,  shall thereupon  be
deemed  to have been converted  into the right to  receive Primergy Common Stock
and cash for any fractional shares, or New NSP Preferred Stock, as the case  may
be, pursuant to the Merger Agreement.

    After  the Effective  Time or  upon receipt of  a valid  demand for payment,
whichever is later, New NSP (as the successor to NSP in the Mergers) must  remit
to  each dissenting shareholder  who complied with the  requirements of the MBCA
the amount New NSP estimates to be  the fair value of such shareholder's  shares
of  NSP Common Stock or  NSP Preferred Stock, as the  case may be, plus interest
accrued at a statutory rate from the  fifth day after the Effective Time to  the
date  of payment. The payment also must be accompanied by certain financial data
relating to  NSP, New  NSP's estimate  of the  fair value  of the  shares and  a
description  of  the method  used  to reach  such estimate,  and  a copy  of the
applicable provisions of the MBCA with a brief description of the procedures  to
be  followed in demanding  supplemental payment. The  dissenting shareholder may
decline to accept  the amount  remitted by  New NSP  and demand  payment for  an
amount  equal to the dissenting shareholder's estimate  of the fair value of the
NSP Common Stock or  NSP Preferred Stock,  as the case may  be. Failure to  make
such  demand  within 30  days  after the  notice is  given  by NSP  entitles the
dissenting shareholder only to the amount initially remitted by New NSP. If  New
NSP  fails to  remit payment  within 60  days of  the deposit  of the  NSP stock
certificates or  the  imposition  of  transfer  restrictions  on  uncertificated
shares,  it shall return all deposited  NSP Certificates and cancel all transfer
restrictions; however, New NSP may again give notice regarding the procedure  to
exercise  dissenters' rights and require deposit or restrict transfer at a later
time.   If    a    dissenting    shareholder   believes    that    the    amount

                                       58
<PAGE>
remitted  is less than the  fair value of the NSP  Common Stock or NSP Preferred
Stock, as  the  case may  be  (including statutory  interest),  such  dissenting
shareholder may give written notice to New NSP of his or her own estimate of the
fair  value of the shares, plus interest, within 30 days after New NSP mails its
remittance, and  demand  payment  of  the  difference.  Otherwise  a  dissenting
shareholder is entitled only to the amount remitted by New NSP.

    If  New NSP  receives a  demand from  a dissenting  shareholder to  pay such
difference, it shall, within 60 days  after receiving the demand, either pay  to
the  dissenting shareholder the  amount demanded or agreed  to by the dissenting
shareholder after discussion with New NSP or file in court a petition requesting
that the court determine the fair value of the shares of NSP Common Stock or NSP
Preferred Stock, as the case may be, plus interest.

    The court may appoint  one or more appraisers  to receive evidence and  make
recommendations  to the court on the amount of the fair value of the shares. The
court shall determine whether the  dissenting shareholder has complied with  the
requirements  of Section 302A.473 of the MBCA and shall determine the fair value
of the shares, taking into account any and all factors the court finds relevant,
computed by  any  method  or combination  of  methods  that the  court,  in  its
discretion,  sees fit to use. The fair value  of the shares as determined by the
court is binding on all dissenting shareholders  and may be less than, equal  to
or  greater  than the  market  price of  the Primergy  Common  Stock or  New NSP
Preferred Stock, as the case may be, to be issued to non-dissenting shareholders
for their shares of NSP Common Stock or NSP Preferred Stock, as the case may be,
if the Mergers are completed. If the court determines that the fair value of the
shares is in excess of the amount, if  any, remitted by New NSP, then the  court
will  enter a judgment  for cash in  favor of the  dissenting shareholders in an
amount by which the value determined  by the court, plus interest, exceeds  such
amount  previously remitted. A dissenting shareholder  will not be liable to New
NSP if the amount, if  any, originally remitted to  such shareholder by New  NSP
exceeds the fair value of the shares, as determined by the court, plus interest.

    Costs  of the court proceeding shall be determined by the court and assessed
against New NSP, except that  part or all of the  costs may be assessed  against
any dissenting shareholders whose actions in demanding supplemental payments are
found by the court to be arbitrary, vexatious or not in good faith.

    If  the  court finds  that New  NSP  did not  substantially comply  with the
relevant dissenters' provisions of the MBCA,  the court may assess the fees  and
expenses,  if any, of  attorneys or experts  as the court  deems equitable. Such
fees and expenses may also be assessed against any party if the court finds that
such party in bringing the proceeding has acted arbitrarily, vexatiously or  not
in good faith, and may be awarded to a party injured by those actions. The court
may  award,  in  its  discretion,  fees and  expenses  of  an  attorney  for the
dissenting shareholders out of the amount awarded to such shareholders, if any.

    A shareholder of record may assert  dissenters' rights as to fewer than  all
of  the shares registered in such shareholder's  name only if he or she dissents
with respect to all shares beneficially owned by any one beneficial  shareholder
and  notifies NSP  in writing of  the name and  address of each  person on whose
behalf he  or she  asserts dissenters'  rights.  The rights  of such  a  partial
dissenting  shareholder are determined  as if the  shares as to  which he or she
dissents and his or her other shares  were registered in the names of  different
shareholders.

    Under  Subdivision 4 of Section 302A.471 of  the MBCA, a NSP shareholder has
no right, at law or in equity, to set aside the approval of the Merger Agreement
or the consummation of the Mergers  except if such approval or consummation  was
fraudulent with respect to such shareholder or NSP.

NO WISCONSIN DISSENTERS' RIGHTS

    The WBCL does not give WEC shareholders the right to dissent from and obtain
payment  of the fair value of their shares  in connection with the matters to be
acted upon at the WEC Meeting.

                               REGULATORY MATTERS

    As  indicated  below, consummation  of the  Mergers  is subject  to numerous
regulatory approvals, which are presently anticipated to be received by the last
quarter of  1996.  Set forth  below  is a  summary  of the  material  regulatory
requirements affecting the Mergers.

    STATE APPROVALS AND RELATED MATTERS.  WEPCO, the electric utility subsidiary
of  WEC,  and NSP  have  included a  regulatory plan  in  their filings  for the
requisite state regulatory approvals. The companies propose that the net savings
expected to result from  the Mergers be spread  among the Primergy  shareholders
and  the retail electric customers in each of the five state jurisdictions in an
equitable manner. WEPCO and NSP have proposed, as a result of the allocation  of
these  net  savings  among each  of  the  state jurisdictions,  an  average rate
reduction of approximately  1.5% in the  retail electric rates  beginning on  or
about  January 1997 (assuming  that the Mergers  are then effective)  and a rate
freeze through the year  2000, subject to  certain exceptions regarding  matters
beyond  NSP's or WEPCO's control,  such as an increase  in the federal corporate
tax rate.

    NSP is  currently  subject  to  the jurisdiction  of  the  Minnesota  Public
Utilities  Commission  (the  "Minnesota Commission"),  the  North  Dakota Public
Service Commission (the "North Dakota  Commission") and the South Dakota  Public
Utilities Commission (the "South Dakota Commission") with respect to its utility
operations  in those states. NSP-Wisconsin, the utility subsidiary of NSP, which
provides utility service in  Wisconsin and the Upper  Peninsula of Michigan,  is
subject  to the jurisdiction of the Wisconsin Commission and the Michigan Public
Service Commission (the "Michigan Commission").

    WEPCO is  subject  to  the  jurisdiction of  the  Wisconsin  Commission  and
Michigan Commission with respect to retail utility service provided in Wisconsin
and  the  Upper Peninsula  of Michigan.  Wisconsin  Natural provides  retail gas
service in various portions of Wisconsin  and is subject to the jurisdiction  of
the  Wisconsin Commission. As a  result of its ownership  of WEPCO and Wisconsin
Natural, WEC is  a public utility  holding company under  the Wisconsin  Holding
Company Act and is subject to the jurisdiction of the Wisconsin Commission.

    Applications   for  approval  of  the   Mergers  and  related  transactions,
including, in the  case of certain  commissions, the issuance  of securities  in
connection  therewith,  were  filed in  early  August, 1995  with  the Minnesota
Commission, the  Wisconsin  Commission,  the North  Dakota  Commission  and  the
Michigan  Commission. An  application for  disclaimer of  jurisdiction was filed
with the South Dakota Commission concurrently with the other state applications.

    Assuming the requisite regulatory approvals are obtained, New NSP's  utility
operations will remain subject to regulation by the Minnesota, North Dakota, and
South  Dakota Commissions and WEPCO's utility operations (which will include the
operations of  Wisconsin  Natural  and NSP-Wisconsin)  will  remain  subject  to
regulation by the Wisconsin and Michigan Commissions. In addition, assuming such
approvals,  New NSP will become a Wisconsin utility by virtue of its acquisition
of gas utility  properties from  NSP-Wisconsin and  will become  subject to  the
jurisdiction of the Wisconsin Commission with respect to such retail gas utility
service.

    Primergy  will be  a public  utility holding  company (a  "holding company")
under the Wisconsin Holding Company Act and will be subject to the  jurisdiction
of  the Wisconsin Commission to the same extent that WEC is currently subject to
the jurisdiction of the Wisconsin Commission.  The following is a brief  summary
of  certain provisions of the Wisconsin Holding Company Act that currently apply
to WEC and will apply to Primergy.

    The Wisconsin  Holding  Company Act  prohibits  any person  from  forming  a
holding  company or acquiring or holding more than 10% of the outstanding voting
securities of  a holding  company, without  Wisconsin Commission  approval.  The
Wisconsin  Commission, if it  finds the capital of  any public utility affiliate
will be impaired by payment  of a dividend, may  order the utility affiliate  to
limit or cease payment of dividends to the holding company. Various transactions
by  a public  utility affiliate  with others in  the holding  company system are
prohibited, including lending money, guaranteeing

                                       60
<PAGE>
obligations, combined advertising, providing utility service on terms  different
from  those  for  other consumers  in  the  same class,  and,  without Wisconsin
Commission approval after establishment that the utility affiliate will be  paid
at  fair  market value,  certain sales  or leases  of real  property and  use of
services of utility employees. The  Wisconsin Holding Company Act prohibits  (i)
any  public utility affiliate from providing  any non-utility product or service
in a manner  or at  a price that  unfairly discriminates  against any  competing
provider,  (ii) any non-utility activity from being subsidized materially by the
customers of any public utility in the system, (iii) the operation of the system
in any way which  materially impairs the credit,  ability to acquire capital  on
reasonable  terms or ability to provide  safe, reasonable, reliable and adequate
utility service,  of  any public  utility  affiliate  in the  system,  (iv)  any
transfer  by  a public  utility affiliate  to  any other  system company  of any
confidential public  utility  information,  including customer  lists,  for  any
non-utility  purpose, unless the Wisconsin Commission has approved the transfer,
and (v) any termination of the  system's interest in a public utility  affiliate
without   Wisconsin  Commission  approval.   Other  statutory  provisions  which
pre-existed  the  Wisconsin  Holding   Company  Act  include  requirements   for
submission  to the  Wisconsin Commission  for approval  of certain  contracts or
other arrangements for furnishing property or services between a public  utility
and an affiliate.

    The  Wisconsin Holding Company Act  also limits non-utility diversification,
in that,  stated  generally,  the net  book  value  of the  assets  (other  than
investment  in system affiliates)  of all non-utility  affiliates may not exceed
the sum of 25% of  the net book value of  all electric utility affiliates and  a
percentage,  to be  determined by  the Wisconsin  Commission (but  not less than
25%), of the net book value of all other public utility affiliates. In order for
Primergy to be within the foregoing prescribed limits at the time NSP becomes  a
subsidiary  of Primergy, NSP must first become a Wisconsin corporation, which is
the reason  NSP will  be merged  into New  NSP pursuant  to the  Reincorporation
Merger.  Further,  the  Wisconsin  Holding Company  Act  requires  the Wisconsin
Commission to  periodically investigate  the impact  of the  operation of  every
holding  company system on every  public utility affiliate in  the system and to
determine whether each non-utility affiliate does, or can reasonably be expected
to do,  at least  one of  the following:  (a) substantially  retain, attract  or
promote  business activity or employment or provide capital to businesses within
the service territory  of any public  utility affiliate or  certain others,  (b)
increase  or promote energy  conservation or develop,  produce or sell renewable
energy products  or  equipment, (c)  conduct  a business  that  is  functionally
related to the provision of utility service or to the development or acquisition
of  energy resources, and (d) develop  or operate commercial or industrial parks
in the service territory  of any public utility  affiliate. NSP and WEC  believe
that  their  existing  non-utility  businesses  meet  the  requirements  of  the
Wisconsin Holding Company Act.  The Wisconsin Commission  also is authorized  to
order  a holding company to terminate its interest in a public utility affiliate
if the  Wisconsin  Commission  finds  that,  based  upon  clear  and  convincing
evidence,  termination of the  interest is necessary to  protect the interest of
utility investors in a financially healthy utility and the interest of consumers
in reasonably adequate utility service at a just and reasonable price.

    PUBLIC UTILITY HOLDING COMPANY ACT OF 1935.  Primergy is required to  obtain
SEC  approval  under Section  9(a)(2) of  the  1935 Act  in connection  with the
Mergers. Section 9(a)(2) of the  1935 Act provides that  it is unlawful for  any
person  to acquire  any security  of any public  utility company  if that person
owns, or by  virtue of  that transaction will  come to  own, 5% or  more of  the
voting securities of that public utility company and of any other public utility
company,  without the prior approval of the  SEC. An application for approval of
the Mergers will  be filed by  WEC and NSP  at the appropriate  time. Under  the
applicable  standards of the 1935 Act, the SEC is directed to approve a proposed
acquisition unless  it  finds  that  (1)  the  acquisition  would  tend  towards
detrimental  interlocking relations  or a detrimental  concentration of control,
(2) the  consideration to  be paid  in connection  with the  acquisition is  not
reasonable, (3) the acquisition would unduly complicate the capital structure of
the  applicant's holding  company system or  would be detrimental  to the proper
functioning of the applicant's  holding company system,  or (4) the  acquisition
would violate applicable state law. In order to

                                       61
<PAGE>
approve  a proposed  acquisition, the  SEC must  also find  that the acquisition
would tend towards the  development of an integrated  public utility system  and
would   otherwise  conform   to  the   1935  Act's   integration  and  corporate
simplification standards.

    WEC is currently exempt from the registration and other requirements of  the
1935  Act, other than from Section 9(a)(2)  thereof, pursuant to an order of the
SEC under Section  3(a)(1) of the  1935 Act.  The basis of  the exemption  under
Section   3(a)(1)  is  that   WEC  and  its   public  utility  subsidiaries  are
predominantly  intrastate   in  character   and   carry  on   their   businesses
substantially  in a single state in which they are organized (Wisconsin). NSP is
currently exempt from the registration and  other requirements of the 1935  Act,
other  than from Section 9(a)(2) thereof, pursuant  to an order of the SEC under
Section 3(a)(2)  of the  1935 Act.  The  basis of  the exemption  under  Section
3(a)(2)  is that  NSP is  predominantly a  public utility  which carries  on its
utility business  only in  the state  of its  incorporation (Minnesota)  and  in
states contiguous thereto. Neither the Section 3(a)(1) exemption under which WEC
currently  operates nor the Section 3(a)(2)  exemption under which NSP currently
operates will be available to Primergy after consummation of the Mergers.

    Accordingly, upon consummation of the  Mergers, Primergy must register as  a
holding  company under the 1935 Act.  The 1935 Act imposes numerous restrictions
on the  operations of  a registered  holding company  and its  subsidiaries  and
affiliates.  Subject to limited  exceptions, SEC approval  is required under the
1935 Act for a  registered holding company  or any of  its subsidiaries to:  (i)
issue securities, (ii) acquire utility assets from a third person, (iii) acquire
the stock of another public utility, (iv) amend its articles of incorporation or
(v)  acquire stock, extend  credit, pay dividends,  lend money or  invest in any
manner in any other  businesses. SEC approval  under the 1935  Act also will  be
required for certain proposed transactions relating to the Mergers. For example,
SEC  approval will be required for Primergy's issuance of securities pursuant to
the Primergy Stock Incentive Plan, the merger of NSP-Wisconsin into WEPCO  after
the  Mergers,  the transfer  by  NSP of  its  subsidiaries to  Primergy  and the
establishment of a  services corporation to  provide various administrative  and
support services to Primergy and certain of its subsidiaries.

    As  part of the SEC's approval process, the 1935 Act also limits the ability
of registered holding companies to engage in non-utility ventures and  regulates
holding  company  system  service companies  and  the rendering  of  services by
holding company affiliates to the system's utilities.

    The SEC may require, as a condition to its approval of the Mergers, that NSP
and WEC divest  their gas  utility properties and  possibly certain  non-utility
ventures within a reasonable time after the Mergers. In a few cases, the SEC has
allowed the retention of such properties or deferred the question of divestiture
for  a substantial period of time. In those cases in which divestiture has taken
place, the SEC has usually allowed enough time to complete the divestiture so as
to allow the applicant to  avoid a "fire sale" of  the divested assets. NSP  and
WEC  believe strong policy  reasons and prior SEC  decisions exist which support
their retaining their existing gas utility properties and non-utility  ventures,
or,  alternatively, which  support deferring the  question of  divestiture for a
substantial period of time; accordingly, WEC and NSP will request in their  1935
Act  application that NSP and WEC be  allowed to retain, or, in the alternative,
that the question of  divestiture be deferred with  respect to, NSP's and  WEC's
existing gas utility properties and non-utility ventures.

    On  June 20, 1995, the SEC issued  a series of new proposed regulations that
are designed, among other things, to ease the restrictions on and regulation  of
the  activities of  registered holding  companies. At  the same  time, the SEC's
Division  of  Investment  Management  (the   "Division")  issued  a  report   of
legislative  recommendations, including the  Division's preferred recommendation
that Congress repeal the 1935 Act, subject to the transfer of certain  authority
over  the books  and records  of registered  holding companies  to state utility
commissions and  to  the FERC.  The  report also  recommended  liberalizing  the
interpretation  of the SEC's regulations  to permit registered holding companies
to own both electric  and gas utility systems  where the affected states  agree.
There  is  no  assurance  that  the regulations  proposed  by  the  SEC  will be
implemented or that the suggestions made in the

                                       62
<PAGE>
Division's report  will be  adopted.  To the  extent that  some  or all  of  the
regulations  and recommendations  are implemented, however,  restrictions on and
regulation of Primergy's activities may  be scaled back, and Primergy's  ability
to  retain  ownership of  the gas  utility  properties and  non-utility ventures
currently operated by WEC and NSP would be enhanced.

    FEDERAL POWER ACT.  Section  203 of the Federal  Power Act provides that  no
public  utility shall sell or otherwise dispose of its jurisdictional facilities
or, directly or indirectly, merge or  consolidate such facilities with those  of
any  other person or  acquire any security  of any other  public utility without
first having obtained authorization from the  FERC. The approval of the FERC  is
required  in order to consummate  the Mergers. Under Section  203 of the Federal
Power Act, the FERC  will approve a  merger if it  finds the merger  "consistent
with  the public interest." In reviewing a merger, the FERC generally evaluates:
(i) whether  the merger  will  adversely affect  competition, (ii)  whether  the
merger will adversely affect operating costs and rates, (iii) whether the merger
will  impair the effectiveness of regulation, (iv) whether the purchase price is
reasonable, (v) whether the merger is  the result of coercion, and (vi)  whether
the  accounting treatment is reasonable.  On July 10, 1995,  NSP and WEC filed a
combined application with the FERC requesting that the FERC approve the  Mergers
under  Section  203 of  the Federal  Power Act  (the "NSP/WEC  Application"). In
connection with the NSP/  WEC Application, NSP and  WEC also filed a  comparable
transmission  service tariff and  an interchange agreement  under Section 205 of
the Federal Power Act, to become effective upon consummation of the Mergers.

    In addition,  NSP  and  NSP-Wisconsin  hold  certain  hydroelectric  project
licenses,  as well  as certificates  of public  convenience and  necessity under
Section 7  of the  Natural  Gas Act.  The merger  of  NSP into  New NSP  and  of
NSP-Wisconsin  into Wisconsin  Energy Company  will constitute  transfers of the
hydroelectric project licenses  and the certificates  of public convenience  and
necessity, requiring approval from the FERC.

    Furthermore,  prior to the mergers of NSP  into New NSP and of NSP-Wisconsin
into Wisconsin Energy Company, the approval of the FERC under Section 204 of the
Federal Power Act is required for New NSP and Wisconsin Energy Company to assume
the debt of NSP and NSP-Wisconsin, respectively.

    ANTITRUST CONSIDERATIONS.    The  HSR  Act and  the  rules  and  regulations
promulgated thereunder provide that certain transactions (including the Mergers)
may  not  be consummated  until certain  information has  been submitted  to the
Antitrust Division of the Department  of Justice (the "Antitrust Division")  and
the  Federal Trade Commission  (the "FTC") and specified  HSR Act waiting period
requirements have been satisfied. The  expiration or earlier termination of  the
HSR Act waiting period would not preclude the Antitrust Division or the FTC from
challenging  the Mergers on antitrust grounds. Neither WEC nor NSP believes that
the Mergers  will  violate  federal  antitrust laws.  If  the  Mergers  are  not
consummated  within 12 months after the expiration or earlier termination of the
initial HSR Act  waiting period, NSP  and WEC  would be required  to submit  new
information  to the Antitrust  Division and the  FTC, and a  new HSR Act waiting
period would have to expire or be earlier terminated before the Mergers could be
consummated. NSP and WEC intend  to file their premerger notifications  pursuant
to  the HSR Act  at such time as  they believe will result  in the expiration or
termination of  the  waiting  period  thereunder within  12  months  before  the
anticipated consummation of the Mergers.

    ATOMIC  ENERGY ACT.  NSP holds NRC operating licenses in connection with its
ownership and operation of the Prairie Island and Monticello nuclear  generating
facilities.  The  operating  licenses  authorize  NSP  to  own  and  operate the
facilities. The Atomic  Energy Act provides  that such a  license or any  rights
thereunder  may not  be transferred  or in any  manner disposed  of, directly or
indirectly, to any person through transfer of control unless the NRC finds  that
such  transfer is in accordance  with the Atomic Energy  Act and consents to the
transfer. Pursuant to the Atomic Energy Act, NSP and WEC will seek approval from
the NRC to reflect the fact that after the Mergers, New NSP, although continuing
to own and operate the Prairie Island and Monticello facilities, will become  an
operating company subsidiary of Primergy.

                                       63
<PAGE>
    OTHER.   NSP  possesses municipal  franchises and  environmental permits and
licenses that may need to be renewed or replaced as a result of the Mergers. NSP
does not  anticipate any  difficulties at  the present  time in  obtaining  such
renewals or replacements.

    GENERAL.   Under the  Merger Agreement, NSP  and WEC have  agreed to use all
reasonable  efforts  to  obtain   all  necessary  material  permits,   licenses,
franchises  and  other  governmental authorizations  necessary  or  advisable to
consummate or  effect the  transactions contemplated  by the  Merger  Agreement.
Various parties may seek intervention in these proceedings to oppose the Mergers
or to have conditions imposed upon the receipt of necessary approvals. While NSP
and  WEC believe that  they will receive the  requisite regulatory approvals for
the Mergers, there can be no assurance as to the timing of such approvals or the
ability of  such parties  to  obtain such  approvals  on satisfactory  terms  or
otherwise.  It is  a condition  to the  consummation of  the Mergers  that final
orders approving the  Mergers be  obtained from  the various  federal and  state
commissions  described above  on terms and  conditions which would  not have, or
would not  be  reasonably likely  to  have, a  material  adverse effect  on  the
business,  assets, financial condition or results  of operations of Primergy and
its prospective  subsidiaries taken  as a  whole, or  on Primergy's  prospective
utility  subsidiaries located in the State of  Minnesota taken as a whole, or on
its prospective utility subsidiaries located in the State of Wisconsin taken  as
a  whole, or which would  be materially inconsistent with  the agreements of the
parties contained in the  Merger Agreement. There can  be no assurance that  any
such approvals will not contain terms or conditions that cause such approvals to
fail to satisfy such condition to the consummation of the Mergers.

                              THE MERGER AGREEMENT

    The  following  is  a brief  summary  of  certain provisions  of  the Merger
Agreement, which is attached as Annex A and is incorporated herein by reference.
Such summary is qualified in its entirety by reference to the Merger Agreement.

THE MERGERS

    The Merger Agreement  provides that,  following the approval  of the  Merger
Agreement  by the shareholders of NSP and WEC, and the satisfaction or waiver of
the  other  conditions  to  the  Mergers,  including  obtaining  the   requisite
regulatory  approvals,  NSP  will  be  merged  with  and  into  New  NSP  in the
Reincorporation Merger and, immediately thereafter, WEC Sub will be merged  with
and into New NSP in the NSP Merger.

    If  the Merger Agreement is approved by the shareholders of NSP and WEC, and
the other conditions to the Mergers are satisfied or waived, the closing of  the
Mergers  (the "Closing") will take place  on the second business day immediately
following the date on which the last  of the conditions referred to below  under
"The  Merger Agreement  -- Conditions to  Each Party's Obligation  to Effect the
Mergers" is fulfilled or waived, or at such  other time and date as NSP and  WEC
shall mutually agree (the "Closing Date"). On or after the Closing Date, (i) the
Reincorporation  Merger will  become effective at  the Reincorporation Effective
Time, as specified in the articles of merger filed by New NSP with the Secretary
of State of  each of  the States  of Wisconsin and  Minnesota and  (ii) the  NSP
Merger will become effective at the Effective Time, as specified in the articles
of  merger  filed  by New  NSP  with the  Secretary  of  State of  the  State of
Wisconsin, which will be subsequent to the Reincorporation Effective Time.

    Subject to the condition that the opinions of Goldman Sachs and Barr  Devlin
as  to the  fairness of the  Ratio to  the holders of  NSP Common  Stock and WEC
Common Stock, respectively, shall not have been withdrawn, WEC and NSP agreed in
the Merger Agreement  to call, give  notice of,  convene and hold  a meeting  of
their  respective shareholders as soon as reasonably practicable for the purpose
of securing their approval to the Mergers.

    CONSUMMATION OF THE MERGERS.   Upon the consummation of the  Reincorporation
Merger, pursuant to the Merger Agreement:

    - Each issued and outstanding share of New NSP Common Stock that is owned by
      NSP will be cancelled and will cease to exist.

    - Each  issued and  outstanding share  of NSP  Common Stock,  other than NSP
      Dissenting Shares,  will be  cancelled  and converted  into the  right  to
      receive one share of New NSP Common Stock.

    - Each  issued and outstanding share of  NSP Preferred Stock, other than NSP
      Dissenting Shares,  will be  cancelled  and converted  into the  right  to
      receive  one  share  of New  NSP  Preferred Stock,  with  terms (including
      dividend rates) and designations under  the New NSP Articles identical  to
      those  of  the  cancelled  share  of NSP  Preferred  Stock  under  the NSP
      Articles.

    Upon consummation of the NSP Merger:

    - Each share of New  NSP Common Stock  and each share  of New NSP  Preferred
      Stock  that is owned by New NSP  as treasury stock, by subsidiaries of New
      NSP or by WEC or any of  its subsidiaries, will be cancelled and cease  to
      exist.

    - Each  issued and  outstanding share  of New  NSP Common  Stock (other than
      shares that are cancelled  as described above  and NSP Dissenting  Shares)
      will  be cancelled and converted into the right to receive 1.626 shares of
      Primergy Common Stock.

    - Each issued and outstanding share of  New NSP Preferred Stock (other  than
      shares  of New NSP Preferred Stock  that are cancelled as described above)
      will be  unchanged  as  a  result  of  the  NSP  Merger  and  will  remain
      outstanding thereafter.

                                       65
<PAGE>
    - Each  issued  and  outstanding  share  of WEC  Sub  Common  Stock  will be
      cancelled and converted into one share of New NSP Common Stock; the number
      of shares of WEC Sub Common Stock which shall be so outstanding, cancelled
      and converted will  be equal to  the number  of shares of  New NSP  Common
      Stock issued and outstanding immediately prior to the Effective Time.

    - Each  issued  and  outstanding  share  of  WEC  Common  Stock  will remain
      outstanding, unchanged, as one share of Primergy Common Stock.

    - NSP Dissenting Shares will not be  cancelled and converted into the  right
      to  receive New NSP Common  Stock or New NSP  Preferred Stock, as the case
      may be, in the Reincorporation Merger or, in the case of NSP Common Stock,
      into the right  to receive Primergy  Common Stock in  the NSP Merger,  but
      will be cancelled and converted into such consideration as may be due with
      respect  to such shares pursuant to the applicable provisions of the MBCA,
      unless and until the right of such  holder to receive fair value for  such
      NSP  Dissenting Shares  terminates in accordance  with the  MBCA, in which
      case such shares will cease to be NSP Dissenting Shares and will represent
      the right to receive Primergy Common Stock, or New NSP Preferred Stock, as
      the case may be, pursuant to the Merger Agreement.

    Based upon the  capitalization of NSP  and WEC  on April 28,  1995, and  the
Ratio  of 1.626 shares of  Primergy Common Stock per  share of NSP Common Stock,
holders of NSP Common Stock, as a group, and WEC Common Stock, as a group, would
each have held approximately 50% of  the aggregate number of shares of  Primergy
Common  Stock  that  would  have  been  outstanding  if  the  Mergers  had  been
consummated as of such date.

    If any holder of NSP Common Stock  would be entitled to receive a number  of
shares  of Primergy  Common Stock that  includes a  fraction, then in  lieu of a
fractional share, such holder will be entitled  to receive a cash payment in  an
amount determined by multiplying the fractional share interest by the average of
the last reported sales price, regular way, per share of WEC Common Stock on the
NYSE  Composite Tape for the  ten business days prior  to and including the last
business day on  which NSP  Common Stock  was traded  on the  NYSE, without  any
interest thereon.

    As  soon  as  practicable  after  the  Effective  Time,  a  company mutually
agreeable to WEC  and NSP (the  "Exchange Agent")  will mail to  each holder  of
record  of  a NSP  Certificate which  immediately  prior to  the Reincorporation
Effective Time  represented outstanding  shares of  NSP Common  Stock that  were
cancelled  and became  instead the  right to  receive shares  of Primergy Common
Stock, a  letter  of transmittal  and  instructions  for use  in  effecting  the
surrender  of  the  NSP  Certificates for  certificates  representing  shares of
Primergy Common Stock. Upon surrender of a NSP Certificate to the Exchange Agent
for cancellation, together with a duly  executed letter of transmittal and  such
other documents, if any, as the Exchange Agent shall require, the holder of such
NSP  Certificate will  be entitled  to receive  a certificate  representing that
number of  whole  shares of  Primergy  Common Stock  and  any cash  in  lieu  of
fractional  shares of Primergy Common  Stock which such holder  has the right to
receive pursuant to the provisions  of the Merger Agreement. Until  surrendered,
each  NSP Certificate  will be deemed  at any  time after the  Effective Time to
represent only  the  right  to  receive  upon  such  surrender  the  certificate
representing  shares of Primergy Common Stock and cash in lieu of any fractional
share of Primergy Common Stock.

    The letter of transmittal  may, at the option  of Primergy, provide for  the
ability  of a holder of one or more NSP Certificates to elect that the shares of
Primergy Common Stock to be  received in exchange for  the shares of NSP  Common
Stock  formerly represented  by such surrendered  NSP Certificates  be issued in
uncertificated form  or to  elect that  such shares  be credited  to an  account
established  for such  holder under  Primergy's dividend  reinvestment and stock
purchase plan.

    No dividends or  other distributions  declared or made  after the  Effective
Time  with respect to shares  of Primergy Common Stock  with a record date after
the Effective  Time  will  be  paid  to the  holder  of  any  unsurrendered  NSP
Certificate   and  no  cash  payment  in  lieu  of  fractional  shares  will  be

                                       66
<PAGE>
paid to any such holder until  such NSP Certificate shall be surrendered.  After
such  surrender, subject to applicable  law, there will be  paid to such holder,
without interest, the unpaid dividends  and distributions, and any cash  payment
in lieu of a fractional share, to which such holder is entitled.

    HOLDERS  OF NSP COMMON STOCK SHOULD NOT SEND IN THEIR NSP CERTIFICATES UNTIL
THEY RECEIVE  A  TRANSMITTAL  FORM.  SHAREHOLDERS OF  WEC  AND  HOLDERS  OF  NSP
PREFERRED STOCK NEED NOT EXCHANGE THEIR CERTIFICATES.

DIRECT SUBSIDIARIES AND UNRESTRICTED SUBSIDIARIES

    The  Merger Agreement designates the direct wholly-owned subsidiaries of WEC
and NSP, respectively, as "WEC  Subsidiaries" and "NSP Subsidiaries" (which  are

"Unrestricted  Subsidiaries." The representations and  warranties of WEC and NSP
in the Merger Agreement apply only to, and  the covenants of WEC and NSP in  the

amount of  additional investments  in,  or loans  or capital  contributions,  or
guarantees  or  obligations  that  each  can  allocate  to,  their  Unrestricted
Subsidiaries between the date of the Merger Agreement and the Effective Time.

                                       68
<PAGE>
Subsidiary in  excess of  $350,000,000 (inclusive  of the  amounts budgeted  for
capital  expenditures and acquisitions and  the $50,000,000 basket referenced in
the Merger Agreement), and WEC agreed that it will not make, and will not permit

Reincorporation Effective Time, NSP-Wisconsin will sell and transfer to New  NSP
certain  utility assets located in  the State of Wisconsin  such that, upon such
transfer, New NSP will be a Wisconsin utility.

    The parties also agreed in the Merger Agreement that, prior to the  Closing,
(a)  WEC will take  all actions necessary  so that the  Primergy Articles become
effective no later than the Effective Time;  and (b) NSP will cause the New  NSP
Articles to become effective no later than the Effective Time.

    The  Merger Agreement provides that if the  parties are unable to obtain the
necessary tax ruling  or any of  the statutory approvals  and other  third-party
consents  which are necessary to effect the strategic combination of NSP and WEC
in the  form  contemplated by  the  Merger Agreement,  and  the adoption  of  an
alternative  structure (that otherwise  substantially preserves for  NSP and WEC
the economic benefits  of the  Mergers) would  result in  such conditions  being
satisfied or waived, then the parties shall use their respective best efforts to
effect  a business  combination among themselves  by means of  a mutually agreed
upon structure other than the Mergers that so preserves such benefits.

NO SOLICITATION OF TRANSACTIONS

    The Merger Agreement  provides that  no party  thereto will,  and each  such
party  will cause its Direct  Subsidiaries not to, and  each such party will not
permit  any  of  its  officers,  directors,  employees,  accountants,   counsel,
investment  bankers, financial advisors and other representatives (collectively,
"Representatives") or subsidiaries that are not Direct Subsidiaries to, and each
such party will use its best efforts  to cause such persons not to, directly  or
indirectly: initiate, solicit or encourage, or take any action to facilitate the
making  of any offer  or proposal which  constitutes or is  reasonably likely to
lead to, any Business Combination Proposal (as defined herein), or, in the event
of an unsolicited Business Combination  Proposal, except to the extent  required
by  their  fiduciary duties  under applicable  law  if so  advised in  a written
opinion of outside counsel, engage in negotiations or provide any information or
data to any person relating to any Business Combination Proposal. As used above,
"Business Combination  Proposal"  shall  mean  any  tender  or  exchange  offer,
proposal for a merger, consolidation or other business combination involving any
party  to  the Merger  Agreement or  any  of its  material subsidiaries,  or any
proposal or offer (in each  case, whether or not in  writing and whether or  not
delivered  to the shareholders of  a party generally) to  acquire in any manner,
directly or  indirectly,  a substantial  equity  interest in  or  a  substantial
portion  of  the assets  of any  party to  the  Merger Agreement  or any  of its
material subsidiaries, other than pursuant  to the transactions contemplated  by
the Merger Agreement.

PRIMERGY BOARD OF DIRECTORS

    The  Merger Agreement  provides that  NSP's and  WEC's respective  Boards of
Directors will take  such action  as may  be necessary  to cause  the number  of
directors  comprising the  full Primergy  Board at the  Effective Time  to be 12
persons, six of whom shall be designated by NSP prior to the Effective Time  and
six  of whom shall be designated by WEC prior to the Effective Time. The initial
designation of such  directors among  the three  classes of  the Primergy  Board
shall  be agreed to  by NSP and WEC,  the designees of each  party to be divided
equally among  such  classes. If,  prior  to the  Effective  Time, any  of  such
designees  shall decline or be unable to  serve, the party which designated such
person shall designate another person to serve in such person's stead. To  date,
NSP  and WEC have not decided who, in addition to Messrs. Howard and Abdoo, will
be designated to serve on the Primergy Board after the Effective Time. NSP's and
WEC's respective  Boards of  Directors will  also  take such  action as  may  be
necessary to cause each of the committees of the Primergy Board at the Effective
Time  to consist of two members designated  by NSP and two members designated by
WEC. WEC will select the

                                       69
<PAGE>
chairs of  the  Nominating Committee,  the  Finance Committee  and  the  Nuclear
Oversight  Committee. NSP will select the chairs of the Executive Committee, the
Compensation Committee and the Audit Committee.

INDEMNIFICATION

    The Merger Agreement provides that, to  the extent, if any, not provided  by
an  existing right  of indemnification  or other  agreement or  policy, from and
after the Effective  Time, Primergy shall,  to the fullest  extent permitted  by
applicable  law, indemnify, defend and hold harmless  each person who was at, or
who had been at any time prior to,  April 28, 1995, or who becomes prior to  the
Effective  Time, an officer, director or employee  of any of the parties thereto
or any  subsidiary  (the "Indemnified  Parties")  against all  losses,  expenses
(including   reasonable  attorney's  fees  and  expenses),  claims,  damages  or
liabilities or,  subject  to the  provision  of the  next  succeeding  sentence,
amounts  paid in settlement, arising out of actions or omissions occurring at or
prior to the Effective  Time (and whether  asserted or claimed  prior to, at  or
after the Effective Time) that are, in whole or in part, based on or arising out
of  the fact that such person is or  was a director, officer or employee of such
party, and all such indemnified liabilities to  the extent they are based on  or
arise  out  of  or  pertain  to  the  transactions  contemplated  by  the Merger
Agreement. In the event  of any such loss,  expense, claim, damage or  liability
(whether  or not arising before the Effective  Time), (i) Primergy shall pay the
reasonable fees and  expenses of  counsel selected by  the Indemnified  Parties,
which  counsel  shall  be  reasonably satisfactory  to  Primergy,  and otherwise
advance to  such  Indemnified Party  upon  request reimbursement  of  documented
expenses reasonably incurred, in either case to the extent not prohibited by law
and  upon  receipt of  any  affirmation and  undertaking  required by  law, (ii)
Primergy will  cooperate  in  the defense  of  any  such matter  and  (iii)  any
determination required to be made with respect to whether an Indemnified Party's
conduct  complies  with the  standards  set forth  under  Wisconsin law  and the
Primergy Articles or the  Primergy Bylaws shall be  made by independent  counsel
mutually  acceptable to Primergy  and the Indemnified  Party; PROVIDED, HOWEVER,
that Primergy  shall not  be  liable for  any  settlement effected  without  its
written  consent (which consent shall not  be unreasonably withheld). The Merger
Agreement further provides that  the Indemnified Parties as  a group may  retain
only one law firm with respect to each related matter except to the extent there
is,  in  the  opinion  of  counsel to  an  Indemnified  Party,  under applicable
standards of professional conduct, a  conflict on any significant issue  between
positions  of  such  Indemnified  Party  and  any  other  Indemnified  Party  or
Indemnified Parties.

    In addition, the Merger  Agreement requires that for  a period of six  years
after  the  Effective Time,  Primergy  shall cause  to  be maintained  in effect
policies of directors' and officers'  liability insurance maintained by NSP  and
WEC  for the benefit of those persons who were covered by such policies at April
28, 1995, on terms no less favorable than the terms of such insurance  coverage,
PROVIDED  that Primergy shall not be required to expend in any year an amount in
excess of 200% of the  annual aggregate premiums currently  paid by NSP and  WEC
for such insurance and, if the annual premiums of such insurance coverage exceed
such  amount,  Primergy shall  be obligated  to  obtain a  policy with  the best
coverage available, in the reasonable judgment of the Primergy Board, for a cost
not exceeding  such amount.  Also, the  Merger Agreement  provides that  to  the
fullest  extent not prohibited  by law, from  and after the  Effective Time, all
rights to indemnification existing in favor of the employees, agents,  directors
and officers of NSP, WEC and their respective subsidiaries with respect to their
activities  as such prior to the Effective Time, as provided in their respective
articles of incorporation and bylaws in  effect on April 28, 1995, or  otherwise
in  effect on April  28, 1995, shall  survive the Mergers  and shall continue in
full force and effect for a period of not less than six years from the Effective
Time.

the obligation of NSP to hold the NSP Meeting that the opinion of Goldman  Sachs
attached  hereto as  Annex F shall  not have been  withdrawn, and it  shall be a
condition to the obligation of WEC to  hold the WEC Meeting that the opinion  of
Barr Devlin attached hereto as Annex G shall not have been withdrawn.

    At  any  time  prior to  the  Effective  Time, to  the  extent  permitted by
applicable law, the conditions to NSP's  or WEC's obligations to consummate  the
Mergers may be waived by the other party. Any determination to waive a condition
would  depend upon  the facts  and circumstances  existing at  the time  of such
waiver and would be made by  the waiving party's Board of Directors,  exercising
its  fiduciary duties to such party and  its shareholders. See "-- Amendment and
Waiver."

BENEFIT PLANS

    Except for  the  benefit plans  referred  to in  the  immediately  following
paragraph,  each of the benefit plans of NSP and WEC in effect as of the date of
the Merger Agreement will be continued for the employees or former employees  of
NSP  and WEC and any of their Direct  Subsidiaries who are covered by such plans
immediately prior to the Closing Date, until Primergy otherwise determines after
the Effective Time (subject to any reserved right contained in any such  benefit
plan  to amend, modify, suspend,  revoke or terminate such  plan). To the extent
such benefit plans are not continued,  Primergy or its subsidiaries have  agreed
to  provide, for at least one year  following the Effective Time, benefits which
are no less favorable in the aggregate than the benefits provided under the  NSP
or  WEC benefit plans. Any  employee first hired after  the Closing Date will be
eligible to participate in  any benefit plan maintained,  or contributed to,  by
the  subsidiary, division  or operation employing  such person, so  long as such
person meets the eligibility requirements of such plan.

    Following  the   implementation  of   the  Primergy   Management   Incentive
Compensation  Plan, no additional  awards will be made  under the WEC Short-Term
Performance Plan or the NSP Executive

                                       71
<PAGE>
Incentive Compensation Plan. Subject to shareholder approval thereof at the  NSP
Meeting and the WEC Meeting, the Primergy Management Incentive Compensation Plan
will  go into  effect at the  Effective Time. The  Primergy Management Incentive
Compensation Plan provides for annual cash bonuses, based on percentages of base
salaries, to  be  awarded  based  upon  the  achievement  of  performance  goals
determined  in advance by  the Primergy Compensation  Committee. With respect to
those participants in  the new plan  who are, or  who the Primergy  Compensation
Committee  determines are likely to be, "covered individuals" within the meaning
of Section  162(m)  of the  Code,  the performance  goals  are to  be  objective
standards  that are approved by shareholders in accordance with the requirements
for exclusion from the limits of Section 162(m) of the Code as performance-based
compensation. See "Approval of Primergy  Plans -- Primergy Management  Incentive
Compensation Plan" and Annex L.

    Following  the  implementation  of  the Primergy  Stock  Incentive  Plan, no
additional awards will  be made under  the NSP Long-Term  Incentive Award  Stock
Plan  or  the WEC  1993  Omnibus Stock  Incentive  Plan. Subject  to shareholder
approval thereof at  the NSP  Meeting and the  WEC Meeting,  the Primergy  Stock
Incentive  Plan will go  into effect at  the Effective Time.  The Primergy Stock
Incentive Plan provides for the grant  of stock options, SARs, restricted  stock
and  such  other  awards  based  upon  Primergy  Common  Stock  as  the Primergy
Compensation Committee may  determine, subject  to shareholder  approval of  the
Primergy  Stock Incentive Plan. Primergy intends to reserve 12,000,000 shares of
Primergy Common Stock for  issuance under this  plan. Accordingly, the  Primergy
Stock  Incentive  Plan  is being  submitted  to shareholders  for  approval. See
"Approval of Primergy Plans -- Primergy Stock Incentive Plan" and Annex K.

    At the Effective Time, (i) each outstanding option to purchase shares of NSP
Common Stock under the  NSP Long-Term Incentive Award  Stock Plan (each an  "NSP
Stock  Option") will  constitute an  option to  acquire, on  the same  terms and
conditions (subject to the adjustments necessary to give effect to the Mergers),
shares of Primergy Common Stock based on  the same number of shares of  Primergy
Common  Stock as the holder of such NSP Stock Option would have been entitled to
receive pursuant to the  Mergers had such holder  exercised such option in  full
immediately  prior to the  Effective Time and (ii)  each other outstanding award
under the NSP Long-Term Incentive Award  Stock Plan (each an "NSP Stock  Award")
will constitute an award based upon the same number of shares of Primergy Common
Stock  as the holder of such NSP Stock Award would have been entitled to receive
pursuant to the NSP  Merger had such holder  been the owner, immediately  before
the  Effective Time, of the  shares of NSP Common Stock  on which such NSP Stock
Award is based, and otherwise on the same terms and conditions as governed  such
NSP Stock Award immediately before the Effective Time.

TERMINATION

    The  Merger Agreement  may be  terminated at any  time prior  to the Closing
Date, whether before or after approval by  the shareholders of WEC and NSP:  (a)
by  mutual written consent of the NSP Board  and the WEC Board; (b) by any party
thereto, if the Effective Time  shall not have occurred  on or before April  30,
1997 (which date shall be extended to October 31, 1997 if the required statutory
approvals  and consents have not been obtained  by April 30, 1997, but all other
conditions to  Closing shall  be,  or shall  be  capable of  being,  fulfilled);
PROVIDED, HOWEVER, that such right to terminate the Merger Agreement will not be
available  to any party whose failure to fulfill any obligation under the Merger
Agreement has been the cause  of, or resulted in,  the failure of the  Effective
Time  to occur on or before that date;  (c) by any party thereto if any required
shareholder approval shall  not have  been obtained at  a duly  held meeting  of
shareholders  or at any  adjournment thereof; (d)  by any party  thereto, if any
state or federal law, order, rule or regulation is adopted or issued, which  has
the effect of prohibiting the NSP Merger, or any court of competent jurisdiction
in  the  U.S.  or any  state  shall have  issued  an order,  judgment  or decree
permanently restraining, enjoining or otherwise prohibiting the NSP Merger,  and
such  order, judgement or decree shall  have become final and nonappealable; (e)
by either WEC or NSP, upon two-days' prior  notice to the other party, if, as  a
result  of a tender  offer by a  person other than  WEC or NSP,  or any of their
affiliates,   or    any    written    offer    or    proposal    with    respect

                                       72
<PAGE>
to  a merger of such party, sale of a material portion of such party's assets or
other business combination involving such party (each, a "Business Combination")
by a person  other than WEC  or NSP, or  any of their  affiliates, the Board  of
Directors  of such party determines in good faith that its fiduciary obligations
under applicable law require  that such tender offer  or other written offer  or
proposal be accepted; provided, however, that (i) the Board of Directors of such
party shall have been advised in writing by outside counsel that notwithstanding
a  binding commitment  to consummate  an agreement of  the nature  of the Merger
Agreement entered  into in  the proper  exercise of  their applicable  fiduciary
duties  and notwithstanding  all concessions which  may be offered  by the other
party, such fiduciary duties would also require the directors to reconsider such
commitment as a result of such tender offer or other written offer or  proposal;
and  (ii) prior to any  such termination, such party  shall, and shall cause its
respective financial and legal  advisors to, negotiate with  the other party  to
make  such adjustments in  the terms and  conditions of the  Merger Agreement as
would enable such party to proceed with the transactions contemplated thereby on
such adjusted terms; or (f) by either WEC on the one hand, or NSP, on the  other
hand,  by  written notice  to  the other,  if (i)  there  exist breaches  of the
representations and  warranties on  the part  of the  other made  in the  Merger
Agreement  as  of  the  date  thereof which  breaches,  individually  or  in the
aggregate, would or would be reasonably  likely to result in a material  adverse
effect  on the business,  assets, financial condition,  results of operations or
prospects of the other  party and its  subsidiaries taken as  a whole, and  such
breaches  shall  not have  been remedied  within  20 days  after receipt  by the
breaching party of notice  in writing from  the non-breaching party,  specifying
the nature of such breaches and requesting that they be remedied, (ii) the other
party  (and/or  its  appropriate  subsidiaries)  shall  not  have  performed and
complied in all respects with certain  agreements and covenants relating to  the
absence  of changes  in capitalization or  issuance of securities  or shall have
failed to  perform  and  comply,  in  all  material  respects,  with  its  other
agreements  and  covenants under  the Merger  Agreement or  under the  WEC Stock
Option Agreement or the NSP Stock Option Agreement, as the case may be, and such
failure to perform or comply shall not  have been remedied within 20 days  after
receipt  by  the breaching  party of  notice in  writing from  the non-breaching
party, specifying the nature of such failure and requesting that it be remedied,
or (iii) the Board of Directors of the other party or any committee thereof  (A)
shall  withdraw or modify  in any manner  adverse to such  party its approval or
recommendation of the  Merger Agreement  or the NSP  Merger, (B)  shall fail  to
reaffirm  such approval or  recommendation upon such  party's request, (C) shall
approve or recommend any acquisition of the other party or a material portion of
its assets or any tender offer for the other party's common stock, in each  case
by  a party other than such party or  any of its affiliates or (D) shall resolve
to take any of the actions specified in clause (A), (B) or (C).

    In the event of termination of the Merger Agreement by either WEC or NSP  as
provided  above, there shall be no liability or obligation on the part of either
WEC or NSP or their respective  officers or directors thereunder other than:  to
hold  in strict  confidence all documents  furnished to the  other in accordance
with the Confidentiality Agreement, dated January 17, 1995, as amended on  April
26,  1995 (the  "Confidentiality Agreement"); to  pay certain  fees and expenses
pursuant to certain specified provisions of the Merger Agreement described below
under "-- Termination Fees" and " -- Expenses"; and to comply with certain other
specified provisions of the Merger Agreement.

TERMINATION FEES

    The Merger Agreement provides that if the Merger Agreement is terminated  at
such  time as  it is  terminable by  either (but  not both)  of NSP  and WEC for
breaches of any representations or warranties contained in the Merger  Agreement
as  of the date thereof, or of  agreements and covenants contained in the Merger
Agreement or the WEC  Stock Option Agreement or  NSP Stock Option Agreement,  as
the case may be, pursuant to the provisions of the Merger Agreement described in
clauses (f)(i) and (f)(ii) under "-- Termination" above, then, if such breach is
not  willful,  the  non-breaching  party is  entitled  to  reimbursement  of its
documented out-of-pocket expenses, not to exceed $10,000,000. In the event of  a
termination  pursuant to such  provisions as a  result of a  willful breach, the
non-breaching party will be entitled to its out-of-pocket expenses (which  shall
not be limited to $10,000,000) and any remedies it may have at law or in equity,
PROVIDED that, if at the time of the

                                       73
<PAGE>
breaching  party's willful  breach, there shall  have been  a third-party tender
offer or proposal with respect to a Business Combination involving the breaching
party or one of its affiliates which  at the time of termination shall not  have
been  rejected by  the breaching  party and  withdrawn by  the third  party, and
within two and one-half years of any termination by the non-breaching party, the
breaching party  accepts  an  offer  to consummate  or  consummates  a  Business
Combination  with such third party, then  such breaching party, upon the signing
of a definitive  agreement relating to  such a Business  Combination, or, if  no
such  agreement is signed then at the closing of such Business Combination, will
pay to  the non-breaching  party an  additional fee  equal to  $75,000,000.  The
Merger  Agreement also requires payment of a termination fee of $75,000,000 (and
reimbursement of out-of-pocket expenses)  by one party to  the other in  certain
circumstances,  if (i) the Merger Agreement is terminated (A) as a result of the
acceptance by such party of a third-party tender offer or proposal with  respect
to  a Business  Combination pursuant to  the provisions of  the Merger Agreement
described in clause (e) under "-- Termination" above, (B) following a failure of
the shareholders of such party to grant their approval to the Mergers or (C)  as
a  result of  such party's  material failure  to convene  a shareholder meeting,
distribute proxy materials  and, subject  to its Board  of Directors'  fiduciary
duties, recommend the Merger Agreement and the Mergers to its shareholders; (ii)
at  the  time  of such  termination  or prior  to  the meeting  of  such party's
shareholders there shall have been a  third-party tender offer or proposal  with
respect  to a Business Combination involving such party or any of its affiliates
which shall not  have been rejected  by such  party and withdrawn  by the  third
party; and (iii) within two and one-half years of any such termination described
in clause (i) above, such party or such affiliate accepts an offer to consummate
or consummates a Business Combination with the third party. Such termination fee
and  out-of-pocket expenses referred  to in the previous  sentence shall be paid
upon the signing  of a  definitive agreement between  such party  and the  third
party,  or,  if  no  such agreement  is  signed,  then at  the  closing  of such
third-party Business Combination.

    In  the  event   that  the   Merger  Agreement   becomes  terminable   under
circumstances  in which  a $75,000,000 termination  fee could be  payable by one
party (the "Payor") pursuant to the immediately preceding paragraph, such  event
will also constitute a "Trigger Event" under the Stock Option Agreement pursuant
to  which the Payor  issued an Option to  the other party, so  as to entitle the
other party to require the Payor to repurchase such Option or the Option  Shares
(as  defined herein) issued upon exercise  thereof. The aggregate amount payable
by WEC or NSP, as the case may  be, pursuant to the provisions described in  the
immediately  preceding paragraph and upon a  required repurchase of an Option or
Option Shares pursuant to the WEC Stock Option Agreement or the NSP Stock Option
Agreement,  as  the  case  may  be,  may  not  exceed  $125,000,000   (including
reimbursement of fees and expenses). See "The Stock Option Agreements."

    The  Merger Agreement further provides  that all termination fees constitute
liquidated damages and not a  penalty and, if one party  should fail to pay  any
termination  fee due, the  defaulting party shall  pay the cost  and expenses in
connection with any action taken to  collect payment, together with interest  on
the amount of any unpaid termination fee.

EXPENSES

    Except  as set  forth above, all  costs and expenses  incurred in connection
with the Merger  Agreement and  the transactions contemplated  thereby shall  be
paid by the party incurring such expense, except that those expenses incurred in
connection  with printing  and filing  of this  Joint Proxy Statement/Prospectus
shall be shared equally by WEC and NSP.

AMENDMENT AND WAIVER

    The Merger Agreement may be amended by the directors of the parties thereto,
at any time before or after approval thereof by the shareholders of WEC and  NSP
and  prior to  the Effective  Time, but after  such approvals  no such amendment
shall alter  or  change the  amount  or kind  of  shares, rights  or  manner  of
conversion  of such shares, alter  or change any of  the terms and conditions of
the Merger Agreement  if any  of the  alterations or  changes, alone  or in  the
aggregate, would materially adversely affect the rights of holders of NSP Common
Stock    or    WEC   Common    Stock,   or    alter    or   change    any   term

                                       74
<PAGE>
of the Primergy  Articles as  approved by the  shareholders of  WEC, except  for
alterations  or changes  that could otherwise  be adopted by  the Primergy Board
without the further  approval of such  shareholders. The parties  to the  Merger
Agreement  may extend the time for the  performance of any of the obligations or
other acts  of  the  other  parties  thereto,  waive  any  inaccuracies  in  the
representations  and warranties contained  therein or in  any document delivered
pursuant thereto, and waive compliance with any of the agreements or  conditions
contained in the Merger Agreement to the extent permitted by law.

STANDSTILL PROVISIONS

    Pursuant  to the  Confidentiality Agreement,  NSP and  WEC have  each agreed
(other than as contemplated in the Merger Agreement or Stock Option Agreements),
that they  will not,  until the  second anniversary  of any  termination of  the
Merger  Agreement, (i) acquire any material  portion of the other party's assets
or businesses or in excess of 1% of any class of securities issued by the  other
party;  (ii) seek or propose a business  combination with the other party or any
of its  subsidiaries;  (iii)  seek  or  propose  to  influence  or  control  the
management  or policies of  the other party;  or (iv) enter  into or propose any
discussions, negotiations, arrangements or  understandings with any third  party
with respect to any of the foregoing.

                          THE STOCK OPTION AGREEMENTS

    The  following  is  a  brief  summary  of  the  terms  of  the  Stock Option
Agreements, copies of which are  attached as Annex B and  Annex C and which  are
incorporated  herein by reference. Such summary  is qualified in its entirety by
reference to  the  Stock Option  Agreements.  The Stock  Option  Agreements  are
intended  to increase  the likelihood  that the  Mergers will  be consummated in
accordance with the terms of the Merger Agreement. Consequently, certain aspects
of the Stock Option Agreements may  have the effect of discouraging persons  who
might  now or prior to the Effective Time be interested in acquiring all of or a
significant interest in, or otherwise effecting a business combination with, NSP
or WEC from considering  or proposing such a  transaction, even if such  persons
were  prepared to offer to  pay consideration to shareholders  of NSP or WEC, as
the case may be,  which had a  higher value than the  shares of Primergy  Common
Stock  to be received per share of NSP Common Stock or to be retained by holders
of WEC Common Stock, as the case may be, pursuant to the Merger Agreement.

GENERAL

    Pursuant to mutual  Stock Option Agreements  entered into concurrently  with
the Merger Agreement, WEC has granted to NSP the NSP Option, and NSP has granted
to WEC the WEC Option. As holders of such Options (the "Option Holder"), NSP and
WEC  have the right, under certain  circumstances, to purchase, respectively, up
to (i) with respect to  the NSP Option, 21,773,726  shares of WEC Common  Stock,
and  (ii) with respect to the WEC  Option, 13,387,772 shares of NSP Common Stock
(shares of common stock  purchasable by the  NSP Option and  the WEC Option  are
collectively referred to as the "Option Shares") at a price of $27.675 per share
for  WEC Common Stock and at a price  of $44.075 per share for NSP Common Stock,
such prices being equal to the average of the daily closing sale prices for such
shares on the  NYSE during the  ten NYSE trading  days prior to  the fifth  NYSE
trading  day preceding the date  of the Merger Agreement.  The exercise price is
payable, at the  Option Holder's  option, in cash  or, subject  to any  required
governmental approvals, shares of common stock of the Option Holder.

    The  Options may be exercised by the Option  Holder, in whole or in part, at
any time or from time to time  after the Merger Agreement becomes terminable  by
such Option Holder under circumstances which could entitle such Option Holder to
termination  fees as a result of a Trigger Event (as defined in the Stock Option
Agreements and  described  above  under "The  Merger  Agreement  --  Termination
Fees"),  regardless of  whether the Merger  Agreement is  actually terminated or
whether there occurs  a closing of  any Business Combination.  The Options  will
terminate  upon the earlier of  (i) the Effective Time,  (ii) the termination of
the Merger Agreement  pursuant to its  terms (other than  a termination upon  or
during  the continuance  of a  Trigger Event), or  (iii) 180  days following any
termination of the Merger Agreement upon or during the continuance of a  Trigger
Event  (or, if  at the expiration  of such  180-day period the  Option cannot be
exercised  by  reason  of  any  applicable  judgment,  decree,  order,  law   or
regulation,  ten business days after such impediment to exercise shall have been
removed or shall have become  final and not subject to  appeal, but in no  event
under this clause (iii) later than October 31, 1997).

    Notwithstanding  the foregoing, no Option may be exercised (a) if the Option
Holder is  in  material  breach  of  any  of  its  material  representations  or
warranties,  or  in  material  breach  of any  of  its  covenants  or agreements
contained in the applicable Stock Option  Agreement or in the Merger  Agreement,
or  (b)  until all  necessary regulatory  approvals have  been obtained  for the
acquisition of shares pursuant to such Option.

CERTAIN REPURCHASES

    Under the terms of the Stock Option Agreements, at any time during which the
Option is exercisable (the "Repurchase Period"), the Option Holder has the right
to require the issuer of the Option (the "Issuer") to repurchase from the Option
Holder all or any portion of the Option or, at any time prior to April 30,  1997
(PROVIDED  that  such date  shall  be extended  to  October 31,  1997  under the
circumstances where the date after which  either party may terminate the  Merger
Agreement  has been  extended to October  31, 1997),  all or any  portion of the
Option Shares purchased pursuant to the

                                       76
<PAGE>
exercise of the Option. The amount that the Issuer will pay to the Option Holder
to repurchase the Option  is the difference between  the Market/Offer Price  for
shares  of Issuer common stock as of the  date the Option Holder gives notice of
its intent  to  exercise its  repurchase  rights  (the "Notice  Date")  and  the
exercise  price  for  the Option,  multiplied  by  the number  of  Option Shares
purchasable pursuant to the Option, or the portion thereof to be so repurchased,
but only if  the Market/Offer  Price is greater  than such  exercise price.  The
amount  that the Issuer will  pay to the Option  Holder to repurchase the Option
Shares is the exercise  price paid by  the Option Holder  for the Option  Shares
plus  the difference between the Market/Offer  Price and the exercise price paid
by the Option Holder for the Option  Shares (but only if the Market/Offer  Price
is  greater than such exercise price), multiplied by the number of Option Shares
to be so repurchased. The Stock Option Agreements define "Market/Offer Price" as
the higher of  (A) the price  per share (the  "Offer Price") offered  as of  the
Notice  Date  pursuant  to  any  tender  or  exchange  offer  or  other business
combination offer which was made prior to the Notice Date and not terminated  or
withdrawn as of such date or (B) the Fair Market Value of Issuer common stock as
of  the Notice  Date (which  is defined  in the  Stock Option  Agreements as the
average of the daily closing sale price  for such shares on the NYSE during  the
ten  NYSE trading days prior to the fifth NYSE trading day preceding such date).
The Offer Price for the repurchase by  the Issuer of Option Shares purchased  by
the  Option Holder pursuant to the Option is the highest price per share offered
pursuant to a tender or exchange offer or other business combination offer which
was made during  the Repurchase Period  prior to  the Notice Date.  At any  time
prior  to April 30, 1997  (which date may be extended  to October 31, 1997 under
the circumstances  described above),  the  Option Holder  may also  require  the
Issuer  to sell to  the Option Holder  any shares of  the Option Holder's common
stock delivered by the Option Holder to  the Issuer in payment for the  exercise
price  of the Option,  at the price  attributed to such  shares for such purpose
plus interest at the rate  of 6.5% PER ANNUM (from  the date of the delivery  of
such  shares through  the date  of such repurchase)  less any  dividends paid or
declared and payable thereon.

VOTING

    Each party has  agreed to  vote, until  April 28,  2000, any  shares of  the
capital  stock  of  the  other  party  acquired  pursuant  to  the  Stock Option
Agreements or  otherwise  beneficially  owned  by  such  party  on  each  matter
submitted  to a vote  of shareholders of  such other party  for and against such
matter in the  same proportion as  the vote  of all other  shareholders of  such
other party is voted for and against such matter.

RESTRICTIONS ON TRANSFER

    The  Stock Option  Agreements provide  that, until  April 28,  2000, neither
party may sell, assign, pledge or otherwise dispose of or transfer the shares it
acquires pursuant to the Stock Option Agreements (collectively, the  "Restricted
Shares")  except as specifically provided for in the Stock Option Agreements. In
addition  to  the   repurchase  rights   described  above   under  "--   Certain
Repurchases," subsequent to the termination of the Merger Agreement, the parties
have  the right  to have  such shares  of the  other party  registered under the
Securities Act for sale in a  public offering. The Stock Option Agreements  also
provide  that, following the  termination of the  Merger Agreement, either party
may sell any Restricted Shares pursuant  to a tender or exchange offer  approved
or  recommended, or otherwise determined to be fair and in the best interests of
such other party's shareholders, by a majority of the Board of Directors of such
other party.

                      AMENDMENTS TO AND RESTATEMENT OF WEC
                       RESTATED ARTICLES OF INCORPORATION

    THE INFORMATION  CONTAINED IN  THIS  JOINT PROXY  STATEMENT/PROSPECTUS  WITH
RESPECT  TO THE PROPOSED  AMENDMENTS TO AND  RESTATEMENT OF THE  WEC ARTICLES IS
QUALIFIED IN ITS  ENTIRETY BY  REFERENCE TO THE  TEXT OF  THE PROPOSED  PRIMERGY
ARTICLES ATTACHED HERETO AS ANNEX H AND INCORPORATED HEREIN BY REFERENCE.

    Pursuant  to the terms  of the Merger Agreement,  WEC shareholders are being
asked to consider and approve each  of the WEC Articles Amendments, which  would
amend  and restate the  WEC Articles to (i)  change the name  of WEC to Primergy
Corporation and (ii)  increase the amount  of authorized WEC  Common Stock  from
325,000,000  shares to  750,000,000 shares, thereby  increasing WEC's authorized
capitalization from 340,000,000 shares to 765,000,000 shares (which includes the
15,000,000 shares of WEC Preferred Stock presently authorized). The WEC Articles
as so amended and  restated, attached hereto  as Annex H,  will be the  Primergy
Articles  at the Effective Time and  until thereafter amended in accordance with
the WBCL and the Primergy Articles.

    THE WEC BOARD UNANIMOUSLY RECOMMENDS A VOTE FOR APPROVAL OF EACH OF THE  WEC
ARTICLES  AMENDMENTS.  Approval of  each  of the  WEC  Articles Amendments  is a
condition to consummation of the Mergers. NSP and WEC retain the right to  waive
the approval of the Common Stock Amendment as a condition to the consummation of
the  Mergers.  If approved  by WEC  shareholders,  it is  intended that  the WEC
Articles Amendments  will not  become effective  until immediately  prior to  or
concurrent  with the Effective Time. If,  after WEC shareholder approval of each
of the WEC Articles  Amendments, the Mergers are  not consummated, WEC will  not
file  the WEC Articles Amendments with the  Wisconsin Secretary of State and the
WEC Articles Amendments will therefore not become effective.

NAME CHANGE AMENDMENT

    In the Merger Agreement, WEC agreed to change its name to a name agreed upon
by WEC and NSP. WEC and NSP have agreed upon the name "Primergy Corporation"  as
the  new name for WEC effective at the  Effective Time. Changing the name of WEC
is deemed desirable by WEC  and NSP in order to  properly reflect the nature  of
the   transaction  as  a  "merger-of-equals."   Changing  WEC's  name  does  not
substantively or otherwise alter any of the rights of WEC shareholders.

    The affirmative vote of a majority of  the votes entitled to be cast at  the
WEC  Meeting  by the  holders  of the  outstanding  shares of  WEC  Common Stock
entitled to vote thereon is required for approval of the Name Change Amendment.

COMMON STOCK AMENDMENT

    As of the WEC  Record Date, of  the 325,000,000 shares  of WEC Common  Stock
presently  authorized,  109,936,834  shares  were  issued  and  outstanding, and
approximately 13,091,000 shares of WEC  Common Stock were reserved for  issuance
for  a specific  purpose, as  follows: 4,000,000  shares under  the 1993 Omnibus
Stock Incentive Plan, 6,694,000 shares under Stock Plus, 1,083,000 shares  under
MESP  and 1,314,000 shares under RESP.  An additional 21,773,726 shares (subject
to adjustment as provided  in the WEC Stock  Option Agreement) are reserved  for
issuance  under the WEC Stock Option Agreement,  but the option to purchase such
shares granted to NSP thereunder will terminate at the Effective Time. See  "The
Stock  Option Agreements."  If the  Mergers are  consummated, up  to 114,357,613
additional shares of Primergy Common Stock would be issued to former holders  of
NSP Common Stock pursuant to the Merger Agreement. Additional shares of Primergy
Common  Stock would be issuable to holders of employee stock options to purchase
NSP Common  Stock  that are  outstanding  at the  Effective  Time, and  will  be
converted into options to acquire shares of Primergy Common Stock, upon exercise
of  such  options. Primergy  is  also obligated  under  the Merger  Agreement to
reserve 12,000,000  shares  of Primergy  Common  Stock for  issuance  under  the
Primergy Stock Incentive Plan. See "Approval of Primergy Plans -- Primergy Stock
Incentive Plan."

    The additional 425,000,000 authorized shares of Primergy Common Stock may be
issued  for any proper corporate purpose approved by the Primergy Board. Without
the Common Stock  Amendment, WEC would  have a sufficient  number of  authorized
shares to complete the NSP Merger. However, the

                                       78
<PAGE>
availability  of additional authorized shares will  enable the Primergy Board to
act with flexibility when and as the  need arises to issue additional shares  in
the  future without  the delays necessitated  by having to  obtain a shareholder
vote. Among  the reasons  for issuing  additional shares  would be  to  increase
Primergy's  capital through sales  of Primergy Common Stock,  to engage in other
types of  capital  transactions,  to  undertake  acquisitions,  and  to  satisfy
contractual commitments, including employee stock options and other stock awards
that  may be granted under the Primergy  Stock Incentive Plan. The WEC Board has
not proposed the increase in the amount of authorized WEC Common Stock with  the
intention  of  discouraging  tender  offers or  takeover  attempts  of Primergy.
However, the availability  of additional  authorized shares  for issuance  could
render  more difficult  or discourage a  merger, tender offer,  proxy contest or
other attempt to  obtain control  of Primergy,  which may  adversely affect  the
ability  of  Primergy  shareholders to  obtain  a  premium for  their  shares of
Primergy Common Stock and, accordingly, have  a negative effect on the price  of
Primergy Common Stock.

    WEC management regularly reviews a range of possible financing transactions,
including  the issuance of WEC Common Stock.  Except for (i) shares to be issued
in connection with  the Mergers and  (ii) shares issued  in connection with  the
plans  mentioned above, WEC has  no present intention of  issuing or selling WEC
Common Stock for  any purpose,  but may  do so  if market  and other  conditions
should  indicate that such a  course of action were  advisable. Under the Merger
Agreement, WEC has  agreed, from the  date of the  Merger Agreement through  the
Effective Time or earlier termination of the Merger Agreement, to issue, without
the consent of NSP, no more than 1,600,000 additional shares of WEC Common Stock
for   general  corporate  purposes,  including   issuances  in  connection  with
acquisitions and financings and pursuant to employee benefit plans, stock option
and other incentive compensation  plans, director plans  and stock purchase  and
dividend reinvestment plans.

    If  the  Common  Stock  Amendment  is  approved,  while  the  Primergy Board
generally may issue such additional  authorized shares of Primergy Common  Stock
without  further shareholder approval, such issuances will generally require the
approval of the SEC under the 1935  Act as presently in effect. See  "Regulatory
Matters." In some instances, shareholder approval for the issuance of additional
shares  may be required by law or by  the requirements of the NYSE, on which the
Primergy Common Stock will be listed, or the obtaining of such approvals may  be
otherwise  necessary or desirable.  Except in such cases,  it is not anticipated
that further shareholder authorization will be solicited. Holders of WEC  Common
Stock  are not entitled  to preemptive rights  to subscribe for  or purchase any
part of  any  new  or  additional  issue  of  WEC  Common  Stock  or  securities
convertible into WEC Common Stock.

    The  affirmative vote of a majority of the  votes entitled to be cast at the
WEC Meeting  by  the holders  of  the outstanding  shares  of WEC  Common  Stock
entitled to vote thereon is required for approval of the Common Stock Amendment.

                     DESCRIPTION OF PRIMERGY CAPITAL STOCK

GENERAL

    Pursuant  to the Merger Agreement, no later than the Effective Time, the WEC
Articles will be amended and  restated in the form  attached hereto as Annex  H,
subject  to shareholder approval of  each of the WEC  Articles Amendments at the
WEC Meeting, and,  as so amended  and restated, shall  be the Primergy  Articles
until  thereafter amended in accordance with the WBCL and the Primergy Articles.
See "Amendments to and Restatement  of WEC Restated Articles of  Incorporation."
The authorized capital stock of Primergy, as of the Effective Time, will consist
of  750,000,000  shares  of  Primergy Common  Stock,  and  15,000,000  shares of
preferred stock,  par value  $.01 per  share ("Primergy  Preferred Stock").  The
description  of Primergy capital stock  set forth herein does  not purport to be
complete and is qualified in its entirety by reference to the Primergy  Articles
and the Bylaws of Primergy (the "Primergy Bylaws"), attached hereto as Annexes H
and I, respectively, as well as applicable statutory or other law.

                                       79

PRIMERGY PREFERRED STOCK

    Under the Primergy Articles, subject to any approval of the SEC which may be
required under the 1935 Act, the Primergy Board will be authorized to divide the
Primergy  Preferred Stock into series,  to issue shares of  any such series and,
within the limitations set forth in the Primergy Articles or prescribed by  law,
to  fix and determine the  relative rights and preferences  of the shares of any
series so established, including the dividend rate, redemption price and  terms,
amount  payable upon  liquidation, and  any sinking  fund provisions, conversion
privileges and voting rights. There are  no present plans to issue any  Primergy
Preferred Stock.

PRIMERGY COMMON STOCK

    The  holders  of Primergy  Common  Stock will  be  entitled to  receive such
dividends as the Primergy Board  may from time to  time declare, subject to  any
rights  of holders of Primergy Preferred Stock, if any is issued. Each holder of
Primergy Common Stock  will be entitled  to one  vote per share  on each  matter
submitted to a vote at a meeting of shareholders, subject to any class or series
voting  rights  of  holders of  any  Primergy  Preferred Stock.  The  holders of
Primergy Common Stock will not be entitled to cumulate votes for the election of
directors. In  the  event of  any  liquidation,  dissolution or  winding  up  of
Primergy,  the holders of  Primergy Common Stock,  subject to any  rights of the
holders of  any  Primergy Preferred  Stock,  will  be entitled  to  receive  the
remainder,  if  any,  of the  assets  of  Primergy after  the  discharge  of its
liabilities. Holders of Primergy Common Stock will not be entitled to preemptive
rights to subscribe for or purchase any  part of any new or additional issue  of
stock  or securities convertible into stock.  The Primergy Common Stock does not
contain any redemption provisions or conversion rights.

    The shares of  Primergy Common  Stock to be  issued pursuant  to the  Merger
Agreement,  when so  issued, will  be fully  paid and  nonassessable. However, a
Wisconsin statute imposes on the shareholders  of a corporation a liability  "to
an  amount equal to the par value of shares owned by them respectively . . . for
all debts owing to employees of the corporation for services performed for  such
corporation,  but not exceeding  6 months' service  in any one  case." In a case
involving shares in a privately held corporation, the Wisconsin Supreme Court by
an evenly divided vote affirmed a lower court decision that "par value," as used
in that provision in  a substantially identical  predecessor statute, means  the
subscription price for the shares.

    Primergy's  ability to pay dividends will  depend primarily upon the ability
of its subsidiaries to pay dividends or otherwise transfer funds to it.  Various
financing  arrangements,  charter  provisions and  regulatory  requirements will
impose  certain  restrictions  on  the  ability  of  Primergy's  public  utility
subsidiaries  to transfer funds to Primergy in the form of cash dividends, loans
or advances.

    So long as any of WEPCO's First Mortgage Bonds, 5 1/8% Series due  September
15,  1998 are outstanding, the most recent series of First Mortgage Bonds issued
under WEPCO's Mortgage and Deed of Trust dated October 28, 1938, as amended  and
supplemented,  WEPCO may not declare any dividend on its common stock, par value
$10.00 per share ("WEPCO  Common Stock"), other than  in WEPCO Common Stock,  or
make any other distribution on, or acquire for value any shares of, WEPCO Common
Stock  (except  in exchange  for  WEPCO Common  Stock)  if, after  giving effect
thereto, the  aggregate of  all such  dividends, distributions  or  acquisitions
between  July 1, 1993 and the last day of the third month preceding the month in
which any such dividend, distribution or acquisition is paid or made exceeds the
sum of $860,062,914 and the net income of WEPCO during such period applicable to
the WEPCO Common Stock. WEPCO's outstanding First Mortgage Bonds of other series
contain similar dividend restrictions.

    So long as any  of Wisconsin Natural's First  Mortgage Bonds, 6 5/8%  Series
due  January 15, 1997 are  outstanding, the only series  of First Mortgage Bonds
outstanding under Wisconsin Natural's Mortgage and  Deed of Trust dated June  1,
1950,  as  amended  and  supplemented, Wisconsin  Natural  may  not  declare any
dividend on its  common stock,  par value  $1.00 per  share ("Wisconsin  Natural
Common  Stock"), other than in Wisconsin Natural Common Stock, or make any other
distribution on,

                                       80
<PAGE>
or acquire for value  any shares of, Wisconsin  Natural Common Stock (except  in
exchange  for Wisconsin Natural  Common Stock), if  after giving effect thereto,
the aggregate  of  all such  dividends,  distributions or  acquisitions  between
December  1, 1991  and the last  day of the  third month preceding  the month in
which any such dividend, distribution or acquisition is paid or made exceeds the
sum of $33,519,275 and  the net income of  Wisconsin Natural during such  period
applicable to the Wisconsin Natural Common Stock.

    No  dividends  on WEPCO  Common  Stock may  be paid  by  WEPCO if  there are
dividends in arrears on WEPCO Preferred Stock.

    The dividend restrictions referred to above  are not expected to impair  the
ability  of WEPCO or Wisconsin Natural to make dividend payments consistent with
past practice.

    See "Description of  New NSP Preferred  Stock -- Limitations  on Payment  of
Dividends  on and  Acquisitions of  NSP Common Stock"  for a  description of the
limitations on  New  NSP's ability  to  pay dividends  on  its common  stock  to
Primergy.

    In  addition,  under the  Wisconsin Holding  Company Act,  Primergy's public
utility affiliates will  be prohibited  from loaning funds,  either directly  or
indirectly,  to  Primergy. Furthermore,  the SEC,  under the  1935 Act,  and the
Wisconsin Commission, under  the Wisconsin  Holding Company Act,  will have  the
power  to preclude the  payment of dividends  by New NSP  and WEPCO to Primergy.
Under the 1935 Act, the SEC will also have the power to preclude the payment  of
dividends by Primergy. See "Regulatory Matters."

    It  is a condition to  consummation of the Mergers  that the Primergy Common
Stock be approved for  listing on the NYSE  subject to official notification  of
issuance.

CERTAIN ANTI-TAKEOVER PROVISIONS

    The  Primergy Articles and Primergy Bylaws  will contain provisions that may
have the effect of discouraging persons from acquiring large blocks of  Primergy
stock  or delaying or preventing  a change in control  of Primergy. The material
provisions which may  have such an  effect are (i)  an anti-greenmail  provision
prohibiting  the purchase of shares of Primergy Common Stock from any person who
the Primergy Board  believes to be  a beneficial owner  of more than  5% of  the
outstanding  shares of  Primergy Common  Stock at  a market  premium unless such
holder owned the shares for at least two years, such purchase was approved by  a
majority  of the combined voting  power of the shareholders,  or the purchase is
pursuant to a tender offer to all  holders of Primergy Common Stock on the  same
terms (which may diminish a person's incentive to acquire a significant block of
Primergy  Common Stock if such person concluded  that it could not be cashed out
at a premium); (ii) classification of the Primergy Board into three classes with
the term of  only one  class expiring each  year; (iii)  a provision  permitting
removal  of a director without  cause only by at  least an 80% shareholder vote;
(iv) authorization for the  Primergy Board (subject  to any required  regulatory
approval)  to issue  Primergy Preferred  Stock in series  and to  fix rights and
preferences of the series (including, among  other things, whether, and to  what
extent,  the shares of any series will have  voting rights and the extent of the
preferences of the  shares of  any series with  respect to  dividends and  other
matters); (v) advance notice procedures with respect to nominations of directors
or proposals other than those adopted or recommended by the Primergy Board; (vi)
and  provisions permitting amendment of certain  of these and related provisions
only by at least  an 80% shareholder  vote at a meeting.  In addition, the  WBCL
contains  supermajority voting/"fair price"  provisions and business combination
provisions that would be applicable to certain mergers, share exchanges or sales
of substantially all assets involving Primergy or a subsidiary and a significant
shareholder and which could have the effect of substantially increasing the cost
to the acquiror  and thus discourage  any such transaction.  See "Comparison  of
Shareholder Rights -- Comparison of Minnesota and Wisconsin Law -- Anti-Takeover
Statutes."

    The  WBCL  permits shareholders  to adopt  an amendment  to the  articles of
incorporation opting out of the supermajority voting/"fair price" provisions but
not the business combination provisions. The Primergy Articles do not opt out of
the supermajority voting/"fair price" provisions and require

                                       81
<PAGE>
an 80%  shareholder  vote  to do  so,  but  do  opt out  of  the  control  share
acquisition  provision of  the WBCL.  See "Comparison  of Shareholder  Rights --
Comparison of Minnesota and Wisconsin Law -- Anti-Takeover Statutes."

    The Wisconsin Statutes also contain provisions specifying that the  approval
of  the Wisconsin Commission is necessary for any acquisition or holding of more
than 10%  of  the  outstanding  voting shares  of  Primergy.  Moreover,  certain
acquisitions  of  outstanding  voting  shares  of  Primergy  would  also require
approval of the SEC under the 1935 Act. See "Regulatory Matters" and "Comparison
of Shareholder Rights."

                     DESCRIPTION OF NEW NSP PREFERRED STOCK

    Pursuant to the  Merger Agreement,  prior to  the Reincorporation  Effective
Time,  the articles of incorporation of New  NSP will be amended and restated in
the form attached hereto as Annex J, and as so amended and restated shall be the
New NSP Articles until  thereafter amended in accordance  with the terms of  the
WBCL  and the  New NSP  Articles. The  express terms  of the  shares of  New NSP
Preferred Stock, as  set forth in  the New  NSP Articles, are  identical to  the
terms  of the corresponding shares  of NSP Preferred Stock,  as set forth in the
NSP Articles. The bylaws of New NSP,  which are attached hereto as Annex O,  are
substantially  the same as  the NSP Bylaws,  except for changes  required by the
WBCL. At the Reincorporation  Effective Time, NSP will  merge with and into  New
NSP, with New NSP being the surviving corporation of the Reincorporation Merger.
The  purpose  of the  Reincorporation  Merger is  to  comply with  the Wisconsin
Holding Company  Act. See  "Regulatory Matters  -- State  Approvals and  Related
Matters."  Each share of NSP Preferred  Stock issued and outstanding immediately
prior to the Reincorporation Effective  Time (other than NSP Dissenting  Shares)
will  be cancelled and converted into the right  to receive one share of New NSP
Preferred Stock with terms (including dividend rates) and designations under the
New NSP Articles  identical to  those of the  cancelled share  of NSP  Preferred
Stock  under the NSP Articles; accordingly, the only differences between a share
of NSP Preferred Stock and a corresponding share of New NSP Preferred Stock  are
those  arising from the differences in the  laws of Minnesota and Wisconsin. See
"Comparison of Shareholder Rights -- Comparison of Minnesota and Wisconsin Law."

    The following is  a description of  both (i)  the NSP Common  Stock and  NSP
Preferred   Stock  as   they  exist  under   the  NSP  Articles   prior  to  the
Reincorporation Merger, and (ii) the New NSP Common Stock and New NSP  Preferred
Stock   as  they   will  exist  under   the  New  NSP   Articles  following  the
Reincorporation Effective Time. As used  in the following description, the  term
"NSP"  refers to  NSP with  respect to any  period prior  to the Reincorporation
Effective  Time  and  to  New  NSP   with  respect  to  any  period  after   the
Reincorporation  Effective Time.  Except as  otherwise indicated,  the following
summary describes  certain  provisions of  the  NSP  Articles and  the  New  NSP
Articles  (a copy of which is attached hereto as Annex J and incorporated herein
by reference), and is qualified in its entirety by reference to the NSP Articles
and the New NSP Articles.

GENERAL

    The capital  stock  of  NSP  consists  of  two  classes:  NSP  Common  Stock
(160,000,000  shares authorized, of which  67,693,931 shares were outstanding as
of July 27,  1995); and  NSP Preferred  Stock (7,000,000  shares authorized,  of
which the following series were outstanding as of July 27, 1995: $3.60 Series --
275,000  shares; $4.08 Series -- 150,000 shares; $4.10 Series -- 175,000 shares;
$4.11 Series -- 200,000 shares; $4.16 Series -- 100,000 shares; $4.56 Series  --
150,000  shares; $6.80 Series -- 200,000 shares; $7.00 Series -- 200,000 shares;
Variable Rate Series A -- 300,000 shares; and Variable Rate Series B --  650,000
shares).  The NSP Board is  authorized to provide for  the issuance from time to
time of  NSP Preferred  Stock in  series  and, as  to each  series, to  fix  the
designation,   dividend  rates  and  time  of  payment,  redemption  price,  and
liquidation price or preference as to assets

                                       82
<PAGE>
in  voluntary  liquidation.  Cumulative  dividends,  redemption  provisions  and
sinking  fund requirements, to the extent that some or all of these features are
or may be  present when NSP  Preferred Stock  is issued, could  have an  adverse
effect  on the availability of  earnings for distribution to  the holders of the
NSP Common Stock or for other corporate purposes.

DIVIDEND RIGHTS

    Before any dividends may  be paid on  the NSP Common  Stock, the holders  of
each  series of NSP Preferred Stock are  entitled to receive all accumulated and
unpaid dividends for past dividend periods at the respective rates provided  for
the shares of the respective series.

LIMITATIONS ON PAYMENT OF DIVIDENDS ON AND ACQUISITIONS OF NSP COMMON STOCK

    So  long as  any shares  of NSP  Preferred Stock  are outstanding, dividends
(other than  dividends payable  in NSP  Common Stock)  or distributions  on,  or
acquisitions for value of, NSP Common Stock (i) may not exceed 50% of net income
of  NSP for the preceding 12-month period, after deducting dividends accruing on
any NSP Preferred Stock during the period, if the sum of the capital represented
by the NSP Common  Stock, premiums on capital  stock (restricted to premiums  on
NSP  Common Stock only by orders of the  SEC), and surplus accounts is less than
20% of the sum of the total capital, premiums on capital stock, surplus accounts
and debt maturing more than  one year after date of  issue, (ii) may not  exceed
75%  of net  income for  such preceding  12-month period,  as adjusted,  if such
capitalization ratio  is 20%  or  more but  less than  25%,  and (iii)  if  such
capitalization  ratio exceeds 25%, such dividends, distributions or acquisitions
may not reduce such  ratio to less  than 25% except to  the extent permitted  by
clauses (i) and (ii) above.

    In  NSP's First Mortgage Indenture,  NSP has covenanted that  the sum of (i)
all dividends and distributions on the NSP Common Stock after September 30, 1954
(other than in NSP Common Stock), and (ii) the cost of all shares of NSP  Common
Stock  acquired by it after that date shall not exceed the sum of (a) the earned
surplus of NSP and certain of its former subsidiary companies, consolidated,  at
September 30, 1954, and (b) an amount equal to the net income of NSP and certain
of  its former  subsidiary companies,  consolidated, earned  after September 30,
1954, after making provisions for all dividends accruing after that date on  NSP
Preferred  Stock  and after  taking into  consideration  all proper  charges and
credits to earned surplus made after that date. In computing net income for  the
purpose of this covenant, there will be deducted an amount, if any, by which 15%
of  the consolidated gross  operating revenues of such  companies, as defined in
the First Mortgage Indenture, after certain deductions, exceeds the aggregate of
the amounts expended for maintenance and provided for depreciation. None of  the
foregoing  provisions are expected  to impair NSP's ability  to pay dividends in
the foreseeable future.

    NSP's Supplemental  and Restated  Trust  Indenture dated  May 1,  1988  (the
"Restated  Indenture")  amends and  restates the  First Mortgage  Indenture. The
Restated Indenture  will not  become  effective and  operative until  all  First
Mortgage Bonds of each series issued under the First Mortgage Indenture prior to
July  1989 shall have been retired through  payment or redemption or, subject to
certain limitations, until the holders of the requisite principal amount of such
First Mortgage Bonds  shall have consented  to the amendments  contained in  the
Restated Indenture (the "Indenture Effective Date"). The Restated Indenture will
replace  the dividend restriction described in  the preceding paragraph with the
requirement that (a)  the sum  of: (i) all  dividends and  distributions on  NSP
Common Stock after the Indenture Effective Date (other than in NSP Common Stock)
and  (ii) the amount,  if any, by which  the consideration given  by NSP for the
purchase or other acquisition of NSP Common Stock after the Indenture  Effective
Date exceeds the consideration received by it after the Indenture Effective Date
from  the sale of  NSP Common Stock,  shall not exceed  (b) the sum  of: (i) the
retained earnings of  NSP at the  Indenture Effective Date,  and (ii) an  amount
equal  to the net income of NSP earned after the Indenture Effective Date, after
deducting all  dividends accruing  after  the Indenture  Effective Date  on  all
classes  and series  of NSP  Preferred Stock.  In computing  net income  for the
purpose of this amended covenant, there will be deducted the amount, if any,  by
which, after the date commencing 365 days prior to the Indenture Effective Date,
the actual expenditures or

                                       83
<PAGE>
charges  for  ordinary repairs  and maintenance  and  the charges  for reserves,
renewals, replacements, retirements,  depreciation and depletion  are less  than
2.50%  of  NSP's  completed depreciable  property  (as defined  in  the Restated
Indenture).

VOTING RIGHTS

    The holders  of  shares of  NSP  Preferred Stock  of  the $3.60  Series  are
entitled  to three votes for  each share held, and the  holders of shares of NSP
Common Stock and shares of NSP Preferred Stock of all other series are  entitled
to  one vote for  each share held, on  all matters submitted to  a vote of NSP's
stockholders; PROVIDED that holders of NSP Common Stock and NSP Preferred  Stock
have cumulative voting rights with respect to election of directors and provided
further  that when dividends  payable on the  NSP Preferred Stock  of any series
outstanding are in default in an amount equivalent to the amount payable thereon
during the immediately preceding 12-month  period, and until such default  shall
have  been remedied, the holders  of shares of NSP  Preferred Stock, voting as a
class and without regard to series, are entitled to elect the smallest number of
directors necessary to constitute a majority of the NSP Board and the holders of
shares of  NSP Common  Stock,  voting as  a class,  are  entitled to  elect  the
remaining directors of NSP.

    The  affirmative  vote  or  consent  of  the  holders  of  various specified
percentages of  NSP Preferred  Stock  is required  to: increase  the  authorized
amount  or prejudicially change the terms  of the NSP Preferred Stock; authorize
stock senior to or  on a parity  with the NSP Preferred  Stock; issue or  assume
unsecured  indebtedness under specified conditions; merge or consolidate with or
into any other corporation, unless such merger or consolidation shall have  been
ordered,  approved or permitted by the SEC under the provisions of the 1935 Act;
or issue additional NSP  Preferred Stock unless certain  net income and  capital
ratio  requirements are met, including a requirement that net income (as defined
in the NSP Articles) for a specified 12-month period shall be not less than  one
and one-half times the sum of the interest requirements for one year on all debt
outstanding  at the date of the proposed issue and the dividend requirements for
one year on all shares of NSP Preferred Stock, including the NSP Preferred Stock
then proposed to be issued but excluding debt or stock to be retired therewith.

REDEMPTION PROVISIONS

    NSP, at its option, may at any time redeem the whole or any part of the  NSP
Preferred  Stock of any series  or of all series upon  at least 30 days' written
notice.

    The orders  of  the  SEC,  in  Files No.  70-3221  and  70-3279,  under  the
provisions  of  the  1935  Act,  permitting  the  Declarations  relating  to NSP
Preferred Stock, $4.08 Series, and NSP Preferred Stock, $4.11 Series, to  become
effective,  contain conditions effective  so long as any  shares of these series
are outstanding that,  in effect,  prohibit NSP from  redeeming or  repurchasing
(through  a sinking  fund or  otherwise) less than  all shares  of NSP Preferred
Stock while there  is any  arrearage in payment  of dividends  on NSP  Preferred
Stock.

CHANGE OF CONTROL

    The NSP Bylaws and the MBCA contain provisions that could discourage or make
more  difficult  a  change of  control  of NSP,  including  provisions requiring
advance notice of  the introduction  by shareholders  of business  at annual  or
special meetings of shareholders of NSP. Following the Reincorporation Effective
Time,  the  rights  of holders  of  New  NSP Preferred  Stock,  including rights
relating to a potential change  of control of New NSP,  will be governed by  the
WBCL. For a discussion of the differences between such provisions under the MBCA
and  the WBCL, see "Comparison of  Shareholder Rights -- Comparison of Minnesota
and Wisconsin Law." Because Primergy will own  all of the New NSP Common  Stock,
and  such New NSP  Common Stock will constitute  in excess of  90% of the voting
power of New NSP, the power to make determinations relating to change of control
matters as they relate to New NSP will belong to Primergy.

LIQUIDATION RIGHTS

    In the  event  of  liquidation, after  the  holders  of all  series  of  NSP
Preferred  Stock  have  received  $100  per share  in  the  case  of involuntary
liquidation, and the then applicable redemption prices in the case of  voluntary
liquidation, plus, in either case, an amount equal to all accumulated and unpaid
dividends,  the holders of  the NSP Common  Stock are entitled  to the remaining
assets. If upon any such liquidation the assets distributable among the  holders
of  the NSP Preferred Stock  of all series shall be  insufficient to pay in full
the amounts to which such holders are entitled, the amount distributable to  the
holders  of all shares of NSP Preferred Stock of all series shall be apportioned
among them ratably in proportion to  the amounts to which they are  respectively
then entitled.

PREEMPTIVE AND SUBSCRIPTION RIGHTS

    No  holder of  NSP Common  Stock or NSP  Preferred Stock  has the preemptive
right to purchase or subscribe for any additional capital stock of NSP.

                        COMPARISON OF SHAREHOLDER RIGHTS

    If the Mergers are consummated, the  persons who were holders of WEC  Common
Stock  immediately  prior  to the  Mergers  will remain  common  shareholders of
Primergy immediately after consummation of the Mergers and their rights will  be
governed  by the Primergy  Articles, the Primergy  Bylaws and the  WBCL. The WEC
Articles, as amended  and restated  by the  WEC Articles  Amendments, which  are
being  submitted  for  shareholder approval  at  the  WEC Meeting,  will  be the
Primergy Articles at the Effective Time.  See "Amendments to and Restatement  of
WEC  Restated Articles  of Incorporation." The  Primergy Bylaws will  be the WEC
Bylaws  as  in  effect  at  the  Effective  Time,  which  are  expected  to   be
substantially in the form of the WEC Bylaws as in effect on the date hereof.

    The  holders of the NSP Common Stock, upon consummation of the Mergers, will
become holders of Primergy Common Stock and their rights will be governed by the
Primergy Articles  and  the Primergy  Bylaws,  and  by the  WBCL.  The  Primergy
Articles  and the Primergy Bylaws are different in certain respects from the NSP
Articles and the NSP Bylaws. In addition, certain differences exist between  the
WBCL and MBCA with respect to shareholders' rights. While it is impracticable to
compare  all  these differences,  material  significant differences  between the
Primergy Articles and the Primergy Bylaws, on the one hand, and the NSP Articles
and the NSP Bylaws, on the other hand, are summarized below under "-- Comparison
of Primergy  Articles and  Bylaws  to NSP  Articles  and Bylaws,"  and  material
similarities  and  differences between  the WBCL  and the  MBCA with  respect to
shareholders' rights are summarized below under "-- Comparison of Minnesota  and
Wisconsin Law."

    The  following discussion is not intended to be complete and is qualified in
its entirety by reference to the Primergy Articles and the Primergy Bylaws which
are attached  to this  Joint Proxy  Statement/ Prospectus  as Annexes  H and  I,
respectively,  the WBCL and  MBCA and the  NSP Articles and  NSP Bylaws. The NSP
Articles and the  NSP Bylaws  are filed as  exhibits to  the Joint  Registration
Statement  of which this  Joint Proxy Statement/Prospectus forms  a part and are
incorporated herein by reference.

COMPARISON OF PRIMERGY ARTICLES AND BYLAWS TO NSP ARTICLES AND BYLAWS

    BOARD OF DIRECTORS

    The NSP Articles  provide that the  NSP Board shall  be composed of  between
three  and seventeen members, as fixed in the NSP Bylaws. The NSP Bylaws provide
that the NSP Board will consist of  twelve directors, but that the NSP Board  or
shareholders may increase such number to not more than fifteen. If the NSP Board
fails  to determine the number  of directors, such number  will be determined by
the shareholders at any annual or special meeting of shareholders. The NSP Board
currently consists of 13 directors. The Primergy Articles will provide that  the
number  of directors will be  fixed by the Primergy  Bylaws. The Primergy Bylaws
provide that the  number of directors  will be fixed  from time to  time by  the
Primergy  Board, but  will not be  less than  three. At the  Effective Time, the
number

                                       85
<PAGE>
of directors  on the  Primergy  Board will  be set  at  12, with  six  directors
designated  by NSP and six directors designated by WEC. The Primergy Board, like
the NSP Board, will be classified into three classes.

    CERTAIN SHARE ACQUISITIONS AND BUSINESS COMBINATIONS

    Certain provisions of the MBCA have the effect of discouraging persons  from
acquiring  large  blocks of  NSP stock  or  delaying or  preventing a  change of
control of NSP.  Under certain  circumstances, these provisions  could have  the
effect  of, among other things, (i) reducing the voting power of shares acquired
by a 20%  shareholder, (ii)  prohibiting a 10%  shareholder from  engaging in  a
business  combination with NSP for four  years following the date of acquisition
of such 10% interest, (iii) prohibiting a potential tender offeror from engaging
in an unequal two-tier tender offer and (iv) prohibiting the payment of a market
premium (i.e., greenmail) to a 5% shareholder who has held such shares for  less
than  two years. See "-- Comparison of  Minnesota and Wisconsin Law" below for a
more complete discussion of such  provisions, including the circumstances  under
which such provisions are triggered.

    The  WBCL  contains  somewhat  similar  provisions.  See  "--  Comparison of
Minnesota and Wisconsin  Law." Under  the Primergy  Articles, however,  Primergy
will opt out of the voting power reduction provision. Although the WBCL contains
an  anti-greenmail  provision, the  Primergy  Articles also  contain  a somewhat
different anti-greenmail provision that  will prohibit Primergy from  purchasing
shares  of Primergy Common  Stock from a  5% holder at  a market premium, unless
such holder has  owned the  shares for  at least  two years,  such purchase  was
approved  by a majority of the combined  voting power of the shareholders or the
purchase is pursuant to a tender offer to all holders on the same terms.

    REMOVAL OF DIRECTORS

    The NSP Articles  and Bylaws  are silent as  to the  procedure for  removing
directors. The MBCA provides that the shareholders may vote to remove any one or
all  directors at any time, with or  without cause, provided that if the company
has cumulative  voting, unless  the entire  board is  removed simultaneously,  a
director  may  not be  removed from  the board  if the  votes cast  against such
removal would have been sufficient to elect  the director at an election of  the
entire board under cumulative voting. The Primergy Bylaws provide that directors
may  be removed for cause by a majority vote of the combined voting power of the
shareholders. Removal without  cause will require  an 80% vote  of the  combined
voting power of the shareholders.

    VACANCIES ON THE BOARD OF DIRECTORS

    The NSP Articles provide that vacancies caused by an increase in the size of
the  board, or by death, resignation, disqualification  or other cause are to be
filled by the remaining directors or by the shareholders. The NSP Bylaws further
provide that the remaining directors, even  though less than a quorum, may  fill
vacancies on the NSP Board.

    The  Primergy  Bylaws  provide  that  all vacancies  may  be  filled  by the
shareholders or the  remaining directors.  If the remaining  directors are  less
than  a quorum, vacancies may be filled by the affirmative vote of a majority of
all directors remaining in office.

    Both the  NSP Bylaws  and  Primergy Bylaws  provide  that any  new  director
elected  to fill a vacancy will serve for the remainder of the then present term
of the class of directors in which the vacancy is being filled.

    AMENDMENTS TO ARTICLES OF INCORPORATION

    The MBCA generally requires that, unless a greater proportion is required by
the articles, amendments to  the articles of incorporation  must be approved  by
the  affirmative vote  of the holders  of the greater  of (i) a  majority of the
voting power  of  the shares  present  and entitled  to  vote on  that  item  of
business, or (ii) a majority of the voting power of the minimum number of shares
entitled  to vote  that would constitute  a quorum. In  certain circumstances, a
vote by class or series is required. Except

                                       86
<PAGE>
for a requirement of  majority approval by the  Preferred Stock to increase  the
authorized amount of Preferred Stock or the authorized number of shares of stock
ranking  on a  parity with such  Preferred Stock  as to assets  or dividends and
except for a requirement of two-thirds approval of the Preferred Stock to change
the  express  terms  and  provisions  of  the  Preferred  Stock  in  any  manner
substantially prejudicial to the holders thereof or to authorize any stock which
is  preferred  as to  assets or  dividends  over such  Preferred Stock,  the NSP
Articles are silent as to amendment procedures.

    The WBCL generally provides that amendments to the articles of incorporation
must be approved by  a majority of  the votes cast, unless  a greater or  lesser
proportion  is  required  by  the  articles  or  bylaws.  The  Primergy Articles
generally  provide  that  amendments  to  the  Primergy  Articles  require   the
affirmative  vote of a majority of the  votes entitled to be cast; provided that
amendments to  certain  sections  (including  those  sections  relating  to  the
preferred  stock provisions, restrictions on  greenmail, the voting requirements
for amending  the Articles  and any  provision  that would  have the  effect  of
rendering    inapplicable   to   Primergy   the   supermajority/fair-price   and
anti-greenmail provisions of the WBCL) require an 80% vote of the shareholders.

    AMENDMENTS TO BYLAWS

    The NSP Articles provide that  the NSP Board has  the authority to make  and
alter  the Bylaws, subject to the power  of the shareholders to change or repeal
such Bylaws. The Primergy Board will have  the power to adopt, amend and  repeal
the  Bylaws, provided that such Bylaws generally may be amended or repealed by a
majority of  the votes  cast at  a shareholders  meeting at  which a  quorum  is
present.  Certain provisions of the  Primergy Bylaws, including those provisions
(i) authorizing shareholder action by unanimous consent, (ii) fixing the  number
of  directors,  (iii)  providing  for  a  classified  board  of  directors, (iv)
establishing procedures for  removing directors, (v)  requiring notice of  board
meetings,  (vi) providing indemnification rights  for officers and directors and
(vii) setting forth the vote required for certain amendments, may not be amended
or repealed without the approval of holders of 80% of the outstanding shares  of
Primergy.

    VOTING/CUMULATIVE VOTING

    The  NSP Articles provide that each share of NSP Common Stock and each share
of NSP Preferred Stock (other than the $3.60 Series Preferred Stock) is entitled
to one vote on each  matter submitted to a vote  of shareholders. Each share  of
the  $3.60 Series Preferred Stock is entitled  to three votes per share. The NSP
Articles also provide for cumulative voting  in connection with the election  of
directors.  The NSP Preferred  Stock has certain special  rights with respect to
the election of directors upon  specified arrearages of dividends. The  Primergy
Articles  provide that each  share of Primergy  Common Stock is  entitled to one
vote on each matter submitted  to a vote of  shareholders. The voting rights  of
Primergy  Preferred Stock, if any,  will be determined by  the Primergy Board at
the time such Primergy Preferred Stock  is issued. The Primergy Articles do  not
provide for cumulative voting in the election of directors.

    SPECIAL MEETINGS OF SHAREHOLDERS; SHAREHOLDER ACTION BY WRITTEN CONSENT

    The  NSP Bylaws provide that special  meetings of shareholders may be called
and held as provided  by the MBCA.  The MBCA provides  that special meetings  of
shareholders  may be called by the  chief executive officer, the chief financial
officer, two or more directors, a person authorized in the articles or bylaws or
a shareholder or shareholders  holding 10% or  more of the  voting power of  the
shares entitled to vote, except that 25% or more of the voting power is required
to  call a special  meeting to consider  any action to,  directly or indirectly,
facilitate or effect a  business combination. The  Primergy Bylaws provide  that
the  Chairman, President or majority of the  Board may call a special meeting of
the shareholders. In addition,  the Primergy Bylaws provide  that if and to  the
extent  required by  the WBCL,  shareholders holding at  least 10%  of the votes
entitled to be cast on an issue may demand that a special meeting be called.

    The NSP Bylaws  are silent  as to whether  shareholders may  take action  by
unanimous  written consent without  a meeting. The  MBCA permits shareholders to
take action by unanimous written consent without a meeting.

                                       87
<PAGE>
    The Primergy Bylaws provide that the shareholders may take action without  a
meeting only by unanimous written consent.

    NOTICE OF SHAREHOLDER PROPOSALS/NOMINATIONS

    The NSP Bylaws require advance notice of the introduction by shareholders of
business at annual or special meetings of shareholders. For any such proposal to
be  properly brought  before an  annual or  special meeting,  a shareholder must
comply with the shareholder proposal requirements under the federal proxy  rules
or  deliver a written notice to  the Secretary of NSP not  less than 20 days nor
more than 90 days prior to the scheduled annual or special meeting, as the  case
may  be; provided that if the date of  such meeting is not disclosed at least 30
days in  advance  of the  meeting  date, a  shareholder  notice will  be  timely
delivered  if received by the  close of business on  the tenth day following the
earlier of the  day on which  notice of the  date of the  scheduled meeting  was
mailed  or the day on which public  disclosure of the meeting date occurred. The
required notice  from  a shareholder  must  contain  (i) a  description  of  the
proposed  business and the  reasons for conducting such  business, (ii) the name
and address of each shareholder supporting  the proposal as it appears on  NSP's
books,  (iii) the class and number of shares owned by each such shareholder, and
(iv) a description of any financial  or other interest of each such  shareholder
in the proposal.

    Primergy's  Bylaws require advance notice of the nomination by a shareholder
of a person for election  as a director or  the introduction by shareholders  of
business  at annual  or special  meetings of  shareholders. For  a nomination or
proposal not included in  the proxy statement to  be properly brought before  an
annual  or special meeting  by shareholders the Secretary  of Primergy must have
received written notice thereof not less than 70 days nor more than 100 days, in
the case of an annual meeting, and a reasonable period of time, in the case of a
special meeting, prior to the meeting. The notice must contain (i) the name  and
address   of  the  shareholder  who  intends   to  make  the  proposal;  (ii)  a
representation that the shareholder  is a holder of  record entitled to vote  at
the  meeting (including  the number  of shares  the shareholder  owns as  of the
record date and the  length of time  the shares have been  held) and intends  to
appear in person or by proxy to make the proposal specified in the notice; (iii)
the  proposal and a brief  supporting statement of such  proposal; and (iv) such
other information regarding the proposal as would be required to be included  in
a proxy statement filed pursuant to the proxy rules of the SEC.

    INDEMNIFICATION/LIMITATION OF LIABILITY

    The  NSP  Bylaws  provide  that  NSP  shall  indemnify  any  person  made or
threatened to be made a party to a proceeding by reason of the former or present
official capacity of the person acting for NSP or acting in an official capacity
with another entity at the direction or  request of NSP, according to the  terms
and  under the procedures provided in the  MBCA. See "-- Comparison of Minnesota
and Wisconsin  Law  --  Indemnification  of Directors  and  Officers."  The  NSP
Articles also limit the personal liability of directors for monetary damages for
breach  of  their  fiduciary  duties,  except  to  the  extent  provided  for by
applicable law for or relating to (i)  breaches of their duty of loyalty to  NSP
or  its shareholders,  (ii) acts  or omissions  not in  good faith  or involving
intentional misconduct or  a knowing  violation of the  law, (iii)  transactions
from  which the directors receive improper  personal benefits or (iv) payment of
an improper dividend, an improper repurchase of NSP stock or an unlawful sale of
securities. The  Primergy Articles  do  not contain  such a  provision  limiting
director  liability, but a comparable limitation  is statutorily mandated by the
WBCL. See "-- Comparison of Minnesota and Wisconsin Law -- Limited Liability  of
Directors."

    The  Primergy Bylaws  provide that Primergy  shall indemnify  to the fullest
extent permitted by law  any person who is  or was a party  or threatened to  be
made  a party to any legal proceeding by  reason of the fact that such person is
or was a director or officer of Primergy, or is or was serving at the request of
Primergy as  a  director or  officer  of another  enterprise,  against  expenses
(including  attorneys  fees), judgments,  fines and  amounts paid  in settlement
actually and  reasonably  incurred  by  such person.  This  right  of  indemnity
includes  the advancement  of expenses upon  receipt of an  undertaking to repay
upon specified conditions. The  Primergy Bylaws also  provide that directors  or
officers who

                                       88
<PAGE>
have been successful on the merits or otherwise in the defense of any proceeding
shall  receive indemnification  within 20  days of  their request.  The right to
indemnification (except in the event of a successful defense, in which case such
indemnification is  automatic) will  be determined  at the  indemnified  party's
election  by  (i) majority  vote of  a quorum  of disinterested  directors, (ii)
independent legal counsel,  (iii) a  panel of three  arbitrators, (iv)  majority
vote  of the shareholders, (v) a court or (vi) such other method provided for in
any additional right to indemnification.

COMPARISON OF MINNESOTA AND WISCONSIN LAW

    In general, as described below, the  MBCA and the WBCL provide  shareholders
with  similar rights and protections. A  comparison of certain provisions of the
MBCA as it applies to NSP  and the WBCL as it  applies to Primergy is set  forth
below:

    CLASSIFIED  BOARD OF DIRECTORS;  REMOVAL OF DIRECTORS;  VACANCIES.  Both the
MBCA and the WBCL allow the Board of Directors to be divided into classes. Under
both  the  MBCA  and  the  WBCL,  absent  a  provision  to  the  contrary  in  a
corporation's  articles of  incorporation or bylaws,  a director  can be removed
with or without cause by the affirmative  vote of the holders of the  proportion
of  the  voting power  of  the shares  of the  classes  or series  such director
represents sufficient to elect such director. Under both the MBCA and the  WBCL,
in  a corporation having  cumulative voting a  director is not  removed from the
board if  there  are cast  against  removal of  such  director the  votes  of  a
proportion  of the voting power sufficient to elect such director at an election
of the entire board under  cumulative voting (unless, in  the case of the  MBCA,
the entire board is removed simultaneously).

    Under  both the MBCA and the WBCL,  absent provisions to the contrary in the
articles of incorporation, vacancies may be filled by the affirmative vote of  a
majority  of the  directors, even  though less  than a  quorum. Under  the WBCL,
vacancies may also be filled by the shareholders.

    INTERESTED DIRECTOR  TRANSACTIONS.    Under  both the  MBCA  and  the  WBCL,
contracts  or transactions in  which one or more  of the corporation's directors
has an interest  are not void  or voidable  solely because of  such interest  or
because  such director  was present at  the directors'  or shareholders' meeting
where such contract or transaction was approved, if certain conditions are  met.
Under  both the WBCL and the MBCA, if  the material facts of the transaction and
the director's interest are fully disclosed and  a vote is taken in good  faith,
such  contracts  or transactions  may  be approved  by  a majority  vote  of the
disinterested directors or by the requisite vote of disinterested  shareholders,
which  under the  WBCL is a  majority and under  the MBCA is  two-thirds. If the
contracts or  transactions  are  shown to  be  fair  and reasonable  as  to  the
corporation  at the time they are authorized, approved or ratified by the board,
separate disinterested  shareholder or  disinterested director  approval is  not
required.

    INDEMNIFICATION  OF DIRECTORS AND OFFICERS.  The WBCL provides for mandatory
indemnification of  a  director  or  officer  against  certain  liabilities  and
expenses  if the director or officer was a  party to a proceeding because of his
or her status as such: (a) to the extent such director or officer is  successful
on  the  merits  or otherwise  in  the defense  of  the proceeding;  and  (b) in
proceedings in which the  director or officer is  not successful in the  defense
thereof,  unless it  is determined that  the liability was  incurred because the
director or officer breached or failed to perform a duty that he or she owes  to
the  corporation and the breach or failure to perform constitutes: (i) a willful
failure to deal fairly  with the corporation or  its shareholders in  connection
with  a  matter in  which the  director or  officer has  a material  conflict of
interest; (ii) a violation of criminal  law, unless the director or officer  had
reasonable  cause to believe that his or her conduct was lawful or no reasonable
cause to believe that his or her conduct was unlawful; (iii) a transaction  from
which  the  director or  officer derived  an improper  personal profit;  or (iv)
willful misconduct.  Indemnification  under the  WBCL  is not  required  if  the
director  or officer  has previously  received indemnification  from any person,
including the  corporation, in  connection with  the same  proceeding. The  WBCL
provides  that a  corporation's articles may  limit its  obligation to indemnify
directors and  officers. The  WBCL specifically  states that  it is  the  public
policy  of Wisconsin to  require or permit indemnification  in connection with a
proceeding involving securities regulation, as described therein, to the  extent
otherwise required or permitted under the WBCL.

                                       89
<PAGE>
    The   MBCA  contains  comparable  provisions.   The  MBCA  provides  that  a
corporation shall indemnify a director or officer, made a party to a  proceeding
because  of  his or  her status  as  such, against  certain liabilities  if such
director or officer  (a) has  not been  indemnified by  another organization  or
employee benefit plan for the same liabilities; (b) has acted in good faith; (c)
has  received  no improper  personal  benefit (and  if  the section  relating to
director's conflicts  of  interest  is  applicable,  its  conditions  have  been
satisfied); (d) in the case of a criminal proceeding, had no reasonable cause to
believe the conduct was unlawful; and (e) reasonably believed his or her conduct
was  in (or,  in certain cases,  was not opposed  to) the best  interests of the
corporation. Under the MBCA, the articles or bylaws may prohibit indemnification
or advances  of  expenses  otherwise required  by  the  indemnification  section
described   above  or  may  impose   additional  conditions  on  indemnification
including, without limitation, monetary limits on indemnification or advances of
expenses, if  the conditions  apply equally  to all  persons or  to all  persons
within a given class.

    LIMITED  LIABILITY OF DIRECTORS.  Both the MBCA and the WBCL provide for the
limitation or elimination of the personal liability of a company's directors  to
the  company  or  its  shareholders  for monetary  damages  for  a  breach  of a
director's fiduciary duty. This immunity  is automatic under Wisconsin law,  but
must  be provided for in  the articles of incorporation  under Minnesota law. In
either state, directors cannot be immunized in certain instances, including: (i)
breach of  the duty  of loyalty;  (ii)  violations of  criminal law;  and  (iii)
willful misconduct. Other limitations specific to each state also exist.

    AMENDMENT  OF  ARTICLES.   The  MBCA  and  WBCL provide  that  the  board of
directors may propose amendments to  a corporation's articles of  incorporation.
The  MBCA  also contains  provisions  permitting a  shareholder  or shareholders
holding 3% or more of the voting power of the shares entitled to vote to propose
amendments. Under  the  MBCA,  proposed  amendments  must  be  approved  by  the
affirmative  vote of the holders of the greater  of (1) a majority of the voting
power of the  shares present and  entitled to vote  on the amendment,  or (2)  a
majority  of the voting power  of the minimum number  of shares entitled to vote
that would constitute a quorum for  the transaction of business at the  meeting,
except where the MBCA or the articles require a larger proportion or number.

    Under  the  WBCL and  unless the  articles,  bylaws adopted  under authority
granted in the articles, the board (if the board is proposing the amendment)  or
the  WBCL requires a greater vote or vote by voting groups, a proposed amendment
is adopted if approved  by a majority  of the votes cast  by every voting  group
entitled  to vote on the amendment. In  addition, both the MBCA and WBCL require
that certain amendments must be approved by a separate vote of a class or series
of stock if, among other things,  the amendment would make a prejudicial  change
to  the rights or  preferences of such  shares. The Primergy  Articles require a
shareholder vote  of  a  majority  of  the  outstanding  shares  to  amend  most
provisions  therein  and an  80% shareholder  vote  to amend  certain provisions
thereof. See "-- Comparison of Primergy Articles and Bylaws to NSP Articles  and
Bylaws -- Amendments to Articles of Incorporation."

    AMENDMENT  OF  BYLAWS.   Under the  MBCA  and WBCL,  unless reserved  by the
articles to the shareholders, the power to adopt, amend or repeal the bylaws  is
generally  vested in  the board,  subject to  the power  of the  shareholders to
adopt, amend, or repeal  bylaws adopted, amended or  repealed by the board.  The
MBCA  also contains provisions permitting  a shareholder or shareholders holding
3% or more  of the  voting power of  the shares  entitled to vote  to propose  a
resolution for action by the shareholders to adopt, amend, or repeal bylaws.

    VOTE  REQUIRED FOR CERTAIN REORGANIZATIONS OR  CONSOLIDATIONS.  The WBCL and
the MBCA both provide for a shareholder vote (except as indicated below and  for
certain  mergers between a parent company and  its 90% owned subsidiary) of: (i)
each corporation that is party to a  plan of merger; (ii) the corporation  whose
shares  will be acquired  in a statutory  share exchange; and  (iii) the selling
corporation for the sale by the  corporation of substantially all of its  assets
if  not in the usual and regular course  of business. The WBCL and the MBCA also
provide for a shareholder vote to approve the dissolution of a corporation.

                                       90
<PAGE>
    Under the MBCA and the WBCL,  unless a higher voting requirement is  imposed
by  the articles  of incorporation or,  in the case  of the WBCL,  by the bylaws
adopted under authority granted by the articles, the vote required to approve  a
plan  of merger, statutory share exchange,  sale of substantially all assets not
in the ordinary course of  business or dissolution is  a majority of the  voting
power of all shares entitled to vote of each corporation whose shareholders have
a  right to vote; approval of a plan  of merger or statutory share exchange (and
in the case of the WBCL, a sale of substantially all assets or dissolution) also
may require the affirmative vote of one or more classes or series of stock.

    Neither the MBCA nor  the WBCL requires  the vote of  the shareholders of  a
surviving  corporation  in  a  merger  if  (i)  the  corporation's  articles  of
incorporation will  not be  amended in  the transaction  (except for  amendments
permitted  to be made by  the board without a  shareholder vote under the WBCL),
(ii) shareholders of the  corporation immediately before  the effective date  of
the  transaction  will hold  the  same number  of  shares with  identical rights
immediately after the  effective date, (iii)  the number of  shares entitled  to
vote immediately after the merger (plus shares issuable upon certain conversions
or  pursuant to certain rights)  does not exceed by more  than 20% the number of
shares entitled to vote immediately before  the transaction (the MBCA refers  to
the  voting power  of the shares  rather than  the number of  shares entitled to
vote);  and  (iv)  the  number  of  participating  shares  of  the   corporation
(outstanding   shares  of  the   corporation  that  entitle   their  holders  to
participate,  without   limitation,  in   distributions  by   the   corporation)
immediately  after the  merger, plus the  number of participating  shares of the
corporation issuable  on the  conversion of,  or on  the exercise  of rights  to
purchase, securities issued in the transaction, will not exceed by more than 20%
the  number of  participating shares of  the corporation  immediately before the
transaction.

    CLASS VOTE FOR CERTAIN REORGANIZATIONS.  Both the MBCA and the WBCL provide,
with certain exceptions, that a  class or series of  shares of a corporation  is
entitled  to vote on a plan of merger  or statutory share exchange as a class or
series if any provision of the plan would, if contained in a proposed  amendment
to  the articles of incorporation, entitle the class or series of shares to vote
as a class or series and, in the case of an exchange, if the class or series  is
included  in  the  plan of  exchange.  In  addition to  the  voting requirements
discussed  above,  anti-takeover  legislation  adopted  in  both  Wisconsin  and
Minnesota   imposes  additional  restrictions  on  mergers  and  other  business
combinations  between  certain  shareholders   and  the  corporation.  See   "--
Anti-Takeover Statutes."

    SHAREHOLDER  ACTION  BY  CONSENT.    Both  the  WBCL  and  the  MBCA  permit
shareholders to  take action  without a  meeting by  unanimous written  consent.
However, Wisconsin also allows a corporation, if it so elects in its articles of
incorporation, to take such action by less than unanimous written consent.

    STATUTORY  SHAREHOLDER LIABILITY.   The  WBCL provides  that shareholders of
Wisconsin domestic  corporations are  personally liable  for all  debts owed  to
employees  for services performed, but not  exceeding six months' service in any
one case. While the  WBCL specifies that  such liability is  limited to the  par
value  of the shares,  this has been  interpreted by a  Wisconsin trial court to
mean the  consideration paid  to a  corporation for  shares. This  decision  was
affirmed  by a split decision of the Wisconsin Supreme Court without any written
opinion and with one justice abstaining.

    DISTRIBUTIONS.  Both  the MBCA and  the WBCL  are the same  in all  material
respects  with  regard  to  distributions. Under  both  statutes,  the  board of
directors may authorize and the corporation may make, subject to any restriction
by  the  articles,   distributions  to  its   shareholders  unless  after   such
distribution  the corporation would not be able  to pay its debts as they become
due or its total assets after the distribution would be less than the sum of its
total liabilities, plus the amount that would be needed, if the corporation were
to be dissolved  at the time  of the distribution,  to satisfy the  preferential
rights  upon dissolution of shareholders  whose preferential rights are superior
to those  receiving the  distribution.  The MBCA  provides  that if  the  amount
available  for  distribution is  insufficient  to satisfy  all  preferences, the
distribution must be made  PRO RATA according  to the order  of priority of  the
preferences by classes and by series within those classes.

                                       91
<PAGE>
    SPECIAL  MEETINGS OF  SHAREHOLDERS.   Under the  WBCL, a  special meeting of
shareholders may be called by the board of directors or by any person authorized
by the  articles  of incorporation  or  bylaws to  call  a special  meeting,  or
pursuant  to a written demand of  the holders of not less  than 10% of the votes
entitled to be cast at such a meeting.

    Under the MBCA, special meetings of  the shareholders may be called for  any
purpose  or purposes at any time, by:  (i) the chief executive officer; (ii) the
chief financial officer; (iii) two or  more directors; (iv) a person  authorized
in  the articles  or bylaws to  call special  meetings; or (v)  a shareholder or
shareholders holding 10% or more of the  voting power of all shares entitled  to
vote, except that a special meeting for the purpose of considering any action to
directly  or indirectly facilitate  or effect a  business combination, including
any action to change or otherwise affect  the composition of the board for  that
purpose,  must  be called  by 25%  or more  of  the voting  power of  all shares
entitled to vote.

    DISSENTERS' RIGHTS.   Both  the  MBCA and  WBCL  entitle shareholders  of  a
corporation  to dissent from and obtain fair value for their shares in the event
of certain corporate  actions. Subject  to certain  exceptions, limitations  and
conditions,  shareholders in both states may dissent  from (1) a plan of merger,
(2) a plan of share exchange, and (3) a sale of all or substantially all of  the
assets  of the  corporation. Under the  MBCA, shareholders are  also entitled to
dissenters' rights in the event of any amendment to the articles that materially
and adversely affects the rights or preferences of the shares of the  dissenting
shareholder  in certain specified  ways. The WBCL provides  that the articles of
incorporation may give this  right to the shareholders.  Both the MBCA and  WBCL
allow  corporations  to  create  additional  dissenters'  rights  by affirmative
provision in the articles or bylaws  or by board resolution. However, under  the
WBCL,  except in a  "Section 180.1130 Business  Combination" (as described below
under "Anti-Takeover Statutes") or unless the articles of incorporation  provide
otherwise,  dissenters' rights are not available to holders of shares registered
on a national securities exchange or quoted  on NASDAQ on the record date for  a
meeting  of shareholders at  which action on  the proposed transaction otherwise
subject to  dissenters'  rights  is to  be  taken.  As a  result,  assuming  the
continued  listing of  the Primergy  Common Stock on  the NYSE,  under the WBCL,
shareholders will not  be entitled  to dissenters'  rights with  respect to  any
future merger, plan of share exchange or sale of all or substantially all of the
assets   of  Primergy  which  might  occur  following  the  Mergers  (unless  it
constitutes a Section 180.1130 Business Combination). There are no current plans
for any such transaction.

    DIRECTOR AND OFFICER DISCRETION.  The WBCL provides that, in discharging his
or her duties to the corporation and  in determining what he or she believes  to
be  in the  best interests  of the  corporation, a  director or  officer may, in
addition to considering the effects of any action on shareholders, consider  (i)
the  effects  of  the  action  on  employees,  suppliers  and  customers  of the
corporation, (ii) the  effects of  the action on  the communities  in which  the
corporation  operates and (iii)  any other factors that  the director or officer
considers pertinent. The MBCA contains comparable provisions. The MBCA  provides
that,  in discharging the duties of the position of director, a director may, in
considering the best interests of the corporation, consider the interests of the
corporation's employees, customers, suppliers, and creditors, the economy of the
state and nation, community  and societal considerations,  and the long-term  as
well  as short-term interests of the  corporation and its shareholders including
the possibility  that  these interests  may  be  best served  by  the  continued
independence of the corporation.

    ANTI-TAKEOVER STATUTES.

    1.   BUSINESS  COMBINATION STATUTES.   The MBCA  and the  WBCL both restrict
corporations from  engaging in  certain enumerated  "business combinations"  (as
defined  therein to  include, generally, a  merger or  statutory share exchange;
sale, lease, exchange, mortgage, pledge, transfer or other disposition of assets
equal to at least 10% (5% under the WBCL) or more of the aggregate market  value
of  all the assets or at least 10% (5% under WBCL) of the aggregate market value
of the outstanding stock  or at least  10% of the earning  power or income;  the
issuance  or transfer of stock with  a market value equal to  at least 5% of the
outstanding stock; adoption of a plan or proposal of liquidation or dissolution,
and certain other  transactions involving an  "interested shareholder"  (defined
generally

                                       92
<PAGE>
as  a shareholder who beneficially  owns at least 10%  of the outstanding voting
power or, under the WBCL,  who is an affiliate  or associate of the  corporation
and  beneficially owned 10% of  the voting power of  the then outstanding voting
stock within the preceding three years)) for a period of four years (three years
under the  WBCL)  following  the  date that  the  person  became  an  interested
shareholder ("share acquisition date"). Under the MBCA, this restriction applies
unless  the business combination or the  acquisition of shares by the interested
shareholder is approved by a committee  of disinterested directors prior to  the
share  acquisition date. A director is deemed disinterested if he or she has not
been an officer or employee of the corporation within the preceding five years.

    Under the WBCL, this restriction applies for three years unless the business
combination or  the  acquisition of  shares  by the  interested  shareholder  is
approved  by  the  board  of  directors prior  to  the  share  acquisition date.
Following such three-year  period, such business  combinations are permitted  if
(i)  the acquisition of shares  was approved by the  board of directors prior to
the share  acquisition date,  (ii) the  business combination  is approved  by  a
majority   of  the  voting  stock  not  beneficially  owned  by  the  interested
shareholder or  (iii) the  consideration  to be  received by  the  corporation's
shareholders satisfies certain "fair price" provisions.

    2.   CONTROL SHARE ACQUISITION STATUTES.  The MBCA reduces the voting rights
of any person acquiring one-fifth, one-third  or a majority of the voting  power
of  the corporation, absent  shareholder approval of  such acquisition. The WBCL
contains similar provisions, except that  the WBCL applies only to  acquisitions
of  more than one-fifth of  the voting power of  the corporation. Under both the
MBCA and  WBCL,  the  person  whose  voting rights  are  reduced  may  demand  a
shareholders  meeting at  which the  shareholders shall  vote on  resolutions to
restore full voting  rights to such  person's shares. If  the shareholders  vote
against  restoring  full  voting  rights, the  MBCA,  unless  expressly provided
otherwise in the articles of incorporation or bylaws, permits the corporation to
redeem a portion of the person's shares at market value.

    The MBCA  and  WBCL  permit  a  corporation to  opt  out  of  the  foregoing
provisions  on control share acquisitions. The  Primergy Articles opt out of the
WBCL control share acquisition provisions.

    3.   ANTI-GREENMAIL STATUTES.   The  MBCA and  WBCL also  contain  so-called
"anti-greenmail"  provisions  which, absent  shareholder approval,  restrict the
ability of publicly held companies to  repurchase voting shares at above  market
value  (as defined in  the MBCA and  the WBCL) from  certain large shareholders,
unless an identical or better  offer to purchase is made  to all owners of  such
shares.  Under the MBCA,  these provisions apply  to purchases from  a person or
group who owns more than 5% of the  voting power of the corporation and who  has
owned  such shares for less than two years. Under the WBCL, the provisions apply
to purchases  during a  take-over offer  of more  than 5%  of the  corporation's
shares  from a  person or  group that  holds more  than 3%  of the corporation's
voting shares and has held the shares for less than two years. These  provisions
may  have the effect  of deterring a shareholder  from acquiring a corporation's
shares with the goal of seeking  to have the corporation repurchase such  shares
at a premium over market value.

    The  WBCL also provides  that shareholder approval is  also required for the
corporation during a take-over offer to sell or option assets of the corporation
which amount to at least 10% of the market value of the corporation, unless  the
corporation  has at  least three  independent directors  (directors who  are not
officers or employees) and a majority  of the independent directors vote not  to
have this provision apply to the corporation.

    4.   FAIR PRICE PROVISIONS.   The MBCA generally  provides that a person who
makes or in any way participates in making a takeover offer (as defined therein)
may not acquire shares of a publicly held corporation within two years following
the last  purchase  of shares  pursuant  to  such takeover  offer,  unless  such
acquisition  is approved by a committee  of disinterested directors prior to any
acquisition by  the  offeror  pursuant  to the  takeover  offer  or  unless  the
shareholders  are permitted a reasonable opportunity  to dispose of their shares
to the  offeror  upon substantially  the  same terms  as  those of  the  earlier
takeover offer.

                                       93
<PAGE>
    The  WBCL  provides that  in addition  to  any approval  otherwise required,
certain  mergers,  share  exchanges  or   sales,  leases,  exchanges  or   other
dispositions involving a public corporation and a 10% holder or affiliate of the
public  corporation who was  a 10% holder  at any time  within the preceding two
years (a  "significant shareholder")  are  subject to  a supermajority  vote  of
shareholders,  unless certain fair price  standards have been met. Specifically,
approval of (i) 80%  of the total  voting power of the  corporation and (ii)  at
least  66 2/3%  of the  voting power not  beneficially owned  by the significant
shareholder  or  its   affiliates  or   associates  is   required,  unless   the
consideration  is in  cash (or  the form  of consideration  used to  acquire the
largest number of shares) and such aggregate per share consideration is equal to
the greater of (a) the highest price paid by such significant shareholder within
the prior two-year period,  (b) the market  value of the shares  on the date  of
commencement  of  a tender  offer by  such significant  shareholder, or  (c) the
highest liquidation or dissolution distribution to which the shareholders  would
be entitled. The Primergy Articles require an 80% shareholder vote to opt out of
the WBCL "fair price" provisions.

                           APPROVAL OF PRIMERGY PLANS

PRIMERGY STOCK INCENTIVE PLAN

    Pursuant  to the Merger Agreement, it was agreed that Primergy would adopt a
stock compensation plan to replace the NSP Long-Term Incentive Award Stock  Plan
and  the  WEC  1993  Omnibus  Stock  Incentive  Plan  (except  with  respect  to
obligations incurred or attributable to employment prior to the Effective  Time)
subject  to approval by shareholders.  Accordingly, the Primergy Stock Incentive
Plan is submitted to the shareholders of NSP and WEC for approval, as more fully
described below. The Primergy Stock Incentive Plan will become effective only if
approved by  shareholders as  described below,  in which  event it  will  become
effective at the Effective Time and will terminate ten years thereafter.

    The  purpose of the Primergy Stock Incentive  Plan is to enable Primergy and
its subsidiaries  and  other  Affiliates  (as  defined  in  the  Primergy  Stock
Incentive  Plan) to attract,  retain and motivate officers  and employees and to
provide Primergy  and its  affiliates  with the  ability to  provide  incentives
directly  linked to the profitability of  Primergy's businesses and increases in
shareholder value and the enhancement of performance relating to customers.

    The Primergy Stock Incentive  Plan has been designed  to comply with  recent
tax  law changes which impose limits on the ability of a public company to claim
tax deductions for compensation paid  to certain highly compensated  executives.
Section 162(m) of the Code generally denies a corporate tax deduction for annual
compensation  exceeding $1,000,000 paid  to the chief  executive officer and the
four other most highly compensated officers  of a public company. Certain  types
of   compensation,  including  performance-based   compensation,  are  generally
excluded from this  deduction limit. In  an effort to  ensure that stock  awards
under  the  Primergy  Stock  Incentive Plan  will  qualify  as performance-based
compensation, which is generally deductible,  the Primergy Stock Incentive  Plan
is  being  submitted to  shareholders of  NSP and  WEC for  approval at  the NSP
Meeting  and  the  WEC  Meeting,   respectively.  While  NSP  and  WEC   believe
compensation  payable  pursuant to  the Primergy  Stock  Incentive Plan  will be
deductible for  federal  income tax  purposes  under most  circumstances,  final
regulations  have not yet been promulgated under  Section 162(m) of the Code and
there can be no assurance in this regard. Moreover, under certain  circumstances
such  as death, disability and change in control (all as defined in the Primergy
Stock Incentive Plan), compensation  not qualified under  Section 162(m) of  the
Code  may  be  payable. By  approving  the  Primergy Stock  Incentive  Plan, the
shareholders will be  approving, among other  things, the performance  measures,
eligibility  requirements and limits on  various stock awards contained therein.
The affirmative vote  of a  majority of  the votes entitled  to be  cast by  the
holders  of the shares  of NSP stock  (NSP Common Stock  and NSP Preferred Stock
voting as a  single class) and  by the holders  of shares of  WEC Common  Stock,
respectively,  represented at the NSP Meeting and the WEC Meeting, respectively,
and entitled to vote thereon (PROVIDED that,  in each case, the total vote  cast
represents  over 50% of the voting power of  all the shares entitled to vote) is
required  to  approve  the  Primergy  Stock  Incentive  Plan  with  respect   to

                                       94
<PAGE>
Section 162(m) of the Code. Such vote will also satisfy the shareholder approval
requirements  of Section 422 of  the Code with respect to  the grant of ISOs and
Rule 16b-3 under  the Exchange Act  ("Rule 16b-3"). THE  BOARDS OF DIRECTORS  OF
EACH  OF NSP AND WEC  UNANIMOUSLY RECOMMEND A VOTE  FOR APPROVAL OF THE PRIMERGY
STOCK INCENTIVE PLAN.

    Set forth below is a summary  of certain important features of the  Primergy
Stock Incentive Plan, which summary is qualified in its entirety by reference to
the actual plan attached as Annex K to this Joint Proxy Statement/Prospectus:

    ADMINISTRATION.   The Primergy Stock Incentive  Plan will be administered by
the Primergy  Compensation Committee  or such  other committee  of the  Primergy
Board  as the  Primergy Board  may from  time to  time designate,  which will be
composed solely of  not less than  two "disinterested persons"  for purposes  of
Rule  16b-3  who also  qualify as  "outside directors"  for purposes  of Section
162(m) of the Code. Among other things, the Primergy Compensation Committee will
have the authority, subject to the  terms of the Primergy Stock Incentive  Plan,
to select officers and employees to whom awards may be granted, to determine the
type  of award as  well as the number  of shares of Primergy  Common Stock to be
covered by each award,  and to determine  the terms and  conditions of any  such
awards.  The Primergy  Compensation Committee  also will  have the  authority to
adopt, alter  and repeal  such administrative  rules, guidelines  and  practices
governing  the  Primergy Stock  Incentive Plan  as it  shall deem  advisable, to
interpret the terms and provisions of the Primergy Stock Incentive Plan and  any
awards  issued thereunder and  to otherwise supervise  the administration of the
Primergy Stock Incentive Plan. All  decisions made by the Primergy  Compensation
Committee  pursuant  to the  Primergy  Stock Incentive  Plan  will be  final and
binding.

    ELIGIBILITY.  Officers and salaried employees of Primergy and its Affiliates
designated by the  Primergy Compensation  Committee who are  responsible for  or
contribute  to the management, growth and profitability of Primergy are eligible
to be granted awards under the Primergy  Stock Incentive Plan. No grant will  be
made under the Primergy Stock Incentive Plan to a director who is not an officer
or  a  salaried  employee.  The initial  determination  of  persons  eligible to
participate in the Primergy  Stock Incentive Plan will  not be made until  after
the  Effective Time by the Primergy  Compensation Committee as then constituted.
Accordingly, it is not possible to estimate  at this time the number of  persons
who will be eligible to participate in the Primergy Stock Incentive Plan.

    PLAN FEATURES.  The Primergy Stock Incentive Plan authorizes the issuance of
up  to  12,000,000 shares  of Primergy  Common  Stock pursuant  to the  grant or
exercise of stock  options, including  ISOs, nonqualified  stock options,  SARs,
restricted  stock and performance units, but  not more than 3,000,000 shares may
be issued  as restricted  stock. No  single participant  may be  granted  awards
pursuant  to the  Primergy Stock  Incentive Plan  covering in  excess of 100,000
shares of Primergy Common Stock in any one calendar year and no participant  may
be  granted performance  units in any  one calendar  year payable in  cash in an
amount that would exceed $1,000,000. Subject to the foregoing limits, the shares
available under  the Primergy  Stock Incentive  Plan can  be divided  among  the
various  types of awards and among the participants as the Primergy Compensation
Committee sees  fit.  The shares  subject  to  grant under  the  Primergy  Stock
Incentive  Plan are to be made available  from authorized but unissued shares or
from treasury shares  as determined  from time to  time by  the Primergy  Board.
Awards  may be granted for such terms as the Primergy Compensation Committee may
determine, except that the term of an ISO may not exceed ten years from its date
of grant. No awards  outstanding on the termination  date of the Primergy  Stock
Incentive  Plan shall be  affected or impaired by  such termination. Awards will
not be transferable,  except by will  and the laws  of descent and  distribution
and,  in the case of nonqualified stock options  and any related SARs, as a gift
to an optionee's children. The  Primergy Compensation Committee will have  broad
authority  to  fix  the  terms  and  conditions  of  individual  agreements with
participants.

                                       95
<PAGE>
    As indicated above, several types of stock-related grants can be made  under
the Primergy Stock Incentive Plan. A summary of these grants is set forth below:

    STOCK  OPTIONS.  The  Primergy Stock Incentive  Plan authorizes the Primergy
Compensation Committee to grant options to purchase Primergy Common Stock at  an
exercise  price (the "option price") which cannot  be less than 100% of the fair
market value of such stock  on the date of  grant. The Primergy Stock  Incentive
Plan   permits  optionees,  with  the  approval  of  the  Primergy  Compensation
Committee, to pay the exercise  price of options in  cash, stock (valued at  its
fair  market value on the  date of exercise) or  a combination thereof. As noted
above, options  may be  granted  either as  ISOs  or nonqualified  options.  The
principal  difference  between  ISOs  and  nonqualified  options  is  their  tax
treatment. See "-- Federal Income Tax Consequences."

    SARS.    The   Primergy  Stock  Incentive   Plan  authorizes  the   Primergy
Compensation  Committee to  grant SARs  in conjunction with  all or  part of any
stock option granted under  the Primergy Stock Incentive  Plan. An SAR  entitles
the  holder to receive  upon exercise the excess  of the fair  market value of a
specified number of shares of Primergy Common Stock at the time of exercise over
the option price per  share specified in the  related stock option. Such  amount
will  be paid to  the holder in shares  of Primergy Common  Stock (valued at its
fair market value on the  date of exercise), cash  or a combination thereof,  as
the  Primergy Compensation  Committee may  determine. An  SAR may  be granted in
conjunction  with  a   contemporaneously  granted   ISO  or   a  previously   or
contemporaneously  granted nonqualified option. Since the  exercise of an SAR is
an alternative to the exercise of an option, the option will be cancelled to the
extent that the SAR is exercised and the SAR will be cancelled to the extent the
option is exercised.

    RESTRICTED STOCK.  The Primergy Stock Incentive Plan authorizes the Primergy
Compensation Committee  to  grant  restricted stock  to  individuals  with  such
restriction  periods as the  Primergy Compensation Committee  may designate. The
Primergy Compensation  Committee may,  prior to  granting shares  of  restricted
stock,  designate certain  participants as "Covered  Employees" upon determining
that such participants are or are expected to be "covered employees" within  the
meaning of Section 162(m)(3) of the Code, and will provide that restricted stock
awards  to  these Covered  Employees cannot  vest unless  applicable performance
goals established by the Primergy Compensation Committee within the time  period
prescribed  by Section 162(m) of the Code are satisfied. These performance goals
must be  based on  the attainment  of specified  levels of  earnings per  share,
market  share,  stock  price, sales,  costs,  net operating  income,  cash flow,
retained earnings, return on equity,  results of customer satisfaction  surveys,
aggregate product price and other product price measures, safety record, service
reliability,   demand-side   management   (including   conservation   and   load
management),  operating  and  maintenance  cost  management,  energy  production
availability,  and individual performance measures.  Such performance goals also
may be based  on the attainment  of specified levels  of Primergy's  performance
under one or more of the measures described above relative to the performance of
other  corporations.  Performance  goals  based  on  the  foregoing  factors are
hereinafter  referred  to  as  "Performance  Goals."  With  respect  to  Covered
Employees,  all Performance Goals must be objective performance goals satisfying
the requirements  for "performance-based  compensation"  within the  meaning  of
Section  162(m)(4) of  the Code.  The Primergy  Compensation Committee  also may
condition the vesting  of restricted stock  awards to participants  who are  not
Covered Employees upon the satisfaction of these or other applicable performance
goals.  The  provisions of  restricted  stock awards  (including  any applicable
Performance Goals) need not be the same with respect to each participant. During
the restriction period, the Primergy Compensation Committee may require that the
stock certificates evidencing restricted shares be held by Primergy.  Restricted
stock  may not be sold, assigned,  transferred, pledged or otherwise encumbered.
Other than  these  restrictions  on  transfer and  any  other  restrictions  the
Primergy  Compensation Committee may  impose, the participant  will have all the
rights of a holder  of stock holding the  class or series of  stock that is  the
subject of the restricted stock award.

    PERFORMANCE  UNITS.    The  Primergy  Stock  Incentive  Plan  authorizes the
Primergy Compensation Committee  to grant performance  units. Performance  units
may be denominated in shares of Primergy

                                       96
<PAGE>
Common Stock or cash, or may represent the right to receive dividend equivalents
with  respect to shares of Primergy Common  Stock, as determined by the Primergy
Compensation Committee. Performance units will be  payable in cash or shares  of
Primergy  Common Stock if applicable Performance Goals  (based on one or more of
the measures  described in  the section  entitled "--  Restricted Stock"  above)
determined  by such committee are achieved during an award cycle. An award cycle
will consist  of  a period  of  consecutive  fiscal years  or  portions  thereof
designated  by the Primergy Compensation  Committee over which performance units
are to be earned. At  the conclusion of a  particular award cycle, the  Primergy
Compensation Committee will determine the number of performance units granted to
a participant which have been earned in view of applicable Performance Goals and
shall  deliver to such participant  (i) the number of  shares of Primergy Common
Stock equal  to  the value  of  performance  units determined  by  the  Primergy
Compensation  Committee to have been earned and/or  (ii) cash equal to the value
of such earned performance  units. The Primergy  Compensation Committee may,  in
its discretion, permit participants to defer the receipt of performance units on
terms and conditions established by the Primergy Compensation Committee.

    The Primergy Compensation Committee will have the authority to determine the
officers  and employees to whom and the time or times at which performance units
shall be  awarded,  the  number  of  performance units  to  be  awarded  to  any
participant,  the duration of the award cycle and any other terms and conditions
of an  award. In  the event  that a  participant's employment  is  involuntarily
terminated  or  in  the  event of  the  participant's  retirement,  the Primergy
Compensation Committee will have the discretion to waive in whole or in part any
or all remaining payment limitations,  PROVIDED, HOWEVER, that the  satisfaction
of  applicable  Performance Goals  by a  designated  Covered Employee  cannot be
waived unless  such  Covered  Employee's  employment  is  terminated  by  death,
disability or change of control.

    AMENDMENT  AND DISCONTINUANCE.   The  Primergy Stock  Incentive Plan  may be
amended, altered  or  discontinued by  the  Primergy Board,  but  no  amendment,
alteration or discontinuance may be made which would (i) impair the rights of an
optionee  under an option  or a recipient  of an SAR,  restricted stock award or
performance unit award previously granted without the optionee's or  recipient's
consent,  except such an amendment made  to qualify the Primergy Stock Incentive
Plan for the exemption  provided by Rule 16b-3  or (ii) disqualify the  Primergy
Stock  Incentive  Plan from  the  exemption provided  by  Rule 16b-3.  Except as
expressly provided  in the  Primergy Stock  Incentive Plan,  the Primergy  Stock
Incentive  Plan may  not be amended  without shareholder approval  to the extent
such approval is required by law or agreement.

    CHANGES IN CAPITALIZATION; CHANGE IN CONTROL.  The Primergy Stock  Incentive
Plan provides that, in the event of any change in corporate capitalization, such
as a stock split, or a corporate transaction, such as any merger, consolidation,
share  exchange, separation, spin-off or other distribution of stock or property
of Primergy,  or  any  reorganization  or partial  or  complete  liquidation  of
Primergy,  the Primergy  Compensation Committee or  the Primergy  Board may make
such substitutions or  adjustments in the  aggregate number and  kind of  shares
reserved  for issuance under  the Primergy Stock Incentive  Plan, in the number,
kind and option price of shares  subject to outstanding stock options and  SARs,
and in the number and kind of shares subject to other outstanding awards granted
under  the Primergy Stock Incentive Plan as  may be determined to be appropriate
by the  Primergy Compensation  Committee  or the  Primergy  Board, in  its  sole
discretion. The Primergy Stock Incentive Plan also provides that in the event of
a  change in control (as  defined in the Primergy  Stock Incentive Plan which is
attached hereto  as  Annex  K)  of  Primergy (i)  any  SARs  and  stock  options
outstanding  as  of  the  date of  the  change  of control  which  are  not then
exercisable and  vested  will become  fully  exercisable and  vested,  (ii)  the
restrictions applicable to restricted stock will lapse and such restricted stock
shall become free of all restrictions and fully vested and (iii) all performance
units  will be considered to be earned  and payable in full and any restrictions
will lapse and such  performance units will  be settled in  cash as promptly  as
practicable.  The holders of  options (other than options  of holders subject to
Section 16(b) of the  Exchange Act that  were granted not  more than six  months
before the change in control) will have the right, for a period of 60 days after
such date, to

                                       97
<PAGE>
surrender  such options in  exchange for a  cash payment based  on the change in
control price (as  defined in the  Primergy Stock Incentive  Plan). However,  if
settlement  in  cash would  disqualify  a transaction  from pooling-of-interests
accounting treatment, the Primergy Compensation Committee may substitute stock.

    FEDERAL INCOME TAX CONSEQUENCES.  The following discussion is intended  only
as  a brief summary of  the federal income tax  rules relevant to stock options,
SARs, restricted stock and performance units. The laws governing the tax aspects
of awards are highly technical and such laws are subject to change.

    - NONQUALIFIED OPTIONS AND  SARS. Upon  the grant of  a nonqualified  option
      (with  or without  an SAR),  the optionee  will not  recognize any taxable
      income and Primergy will not be entitled to a deduction. Upon the exercise
      of such an option or  an SAR, the excess of  the fair market value of  the
      shares  acquired on the exercise of the  option over the option price (the
      "spread"), or the consideration paid to the optionee upon exercise of  the
      SAR,  will  constitute compensation  taxable to  the optionee  as ordinary
      income. In  determining  the  amount  of  the  spread  or  the  amount  of
      consideration  paid to the optionee, the fair market value of the stock on
      the date of  exercise is  used, except  that in  the case  of an  optionee
      subject to the six month short-swing profit recovery provisions of Section
      16(b)  of the Exchange Act (generally officers and directors of Primergy),
      the fair market  value will  be determined six  months after  the date  on
      which  the option  was granted  (if such date  is later  than the exercise
      date) unless such  optionee elects to  be taxed based  on the fair  market
      value  at  the  date of  exercise.  Any  such election  (a  "Section 83(b)
      election") must  be made  and filed  with  the IRS  within 30  days  after
      exercise  in accordance  with the regulations  under Section  83(b) of the
      Code. Primergy, in  computing its  federal income tax,  will generally  be
      entitled  to a deduction in an amount equal to the compensation taxable to
      the optionee.

    - ISOS. An  optionee will  not  recognize taxable  income  on the  grant  or
      exercise  of an  ISO. However, the  spread at exercise  will constitute an
      item includible in  alternative minimum  taxable income,  and thereby  may
      subject  the  optionee to  the alternative  minimum tax.  Such alternative
      minimum tax may be payable even though the optionee receives no cash  upon
      the exercise of his ISO with which to pay such tax.

      Upon  the disposition of shares of stock acquired pursuant to the exercise
      of an ISO after the later of (i)  two years from the date of grant of  the
      ISO or (ii) one year after the transfer of the shares to the optionee (the
      "ISO  Holding Period"), the optionee will recognize long-term capital gain
      or loss,  as the  case may  be,  measured by  the difference  between  the
      stock's  selling price and the exercise price. Primergy is not entitled to
      any tax deduction  by reason of  the grant or  exercise of an  ISO, or  by
      reason  of a disposition of stock received  upon exercise of an ISO if the
      ISO Holding Period  is satisfied.  Different rules apply  if the  optionee
      disposes  of the shares of  stock acquired pursuant to  the exercise of an
      ISO before the expiration of the ISO Holding Period.

    - RESTRICTED STOCK. A participant who is granted restricted stock may make a
      Section 83(b) election to have the  grant taxed as compensation income  at
      the  date of  receipt, with  the result  that any  future appreciation (or
      depreciation) in the value of the  shares of stock granted shall be  taxed
      as  capital gain (or loss) upon a  subsequent sale of the shares. However,
      if the participant does not make a Section 83(b) election, then the  grant
      will  be taxed as compensation income at the full fair market value on the
      date that  the  restrictions  imposed  on  the  shares  expire.  Unless  a
      participant  makes a Section  83(b) election, any  dividends paid on stock
      subject to the restrictions are compensation income to the participant and
      compensation expense to  Primergy. Primergy  is generally  entitled to  an
      income tax deduction for any compensation income taxed to the participant,
      subject to the provisions of Section 162(m) of the Code.

    - PERFORMANCE  UNITS. A participant who has  been granted a performance unit
      award will not  realize taxable  income until the  applicable award  cycle
      expires and the participant is in receipt

                                       98
<PAGE>
      of  the stock distributed in payment of  the award or an equivalent amount
      of cash, at which time such participant will realize ordinary income equal
      to the full fair  market value of  the shares delivered  or the amount  of
      cash   paid.  At  that   time,  Primergy  generally   will  be  allowed  a
      corresponding tax deduction equal to the compensation taxable to the award
      recipient, subject to the provisions of Section 162(m) of the Code.

    NEW PLAN BENEFITS.  It  cannot be determined at  this time what benefits  or
amounts,  if any,  will be received  by or allocated  to any person  or group of
persons under the Primergy Stock Incentive Plan if the Incentive Plan is adopted
or what benefits  or amounts would  have been  received by or  allocated to  any
person  or group of persons  for the last fiscal year  if the Incentive Plan had
been in effect. These determinations will  be made by the Primergy  Compensation
Committee.

PRIMERGY MANAGEMENT INCENTIVE COMPENSATION PLAN

    Pursuant  to the Merger Agreement, it  was agreed that Primergy would adopt,
subject to shareholder  approval, an annual  incentive plan to  replace the  WEC
Short-Term  Performance Plan and  the NSP Executive  Incentive Compensation Plan
(except with respect to obligations incurred or attributable to employment prior
to the  Effective  Time), effective  as  of  the Effective  Time.  The  Primergy
Management  Incentive  Compensation  Plan  (the  "MIC  Plan")  will  not  become
effective with respect to individuals who  are subject to Section 162(m) of  the
Code unless the shareholder approval described below is obtained.

    The  purpose  of the  MIC  Plan is  to  provide a  significant  and flexible
economic opportunity to selected officers and salaried employees of Primergy and
its subsidiaries and other Affiliates (as defined in the MIC Plan) in an  effort
to  reward  their individual  and group  contributions to  Primergy and  to more
closely link the financial interests of management, shareholders and customers.

    The MIC Plan is designed  to take into account  Section 162(m) of the  Code,
which  generally  denies  a  corporate  tax  deduction  for  annual compensation
exceeding $1,000,000 paid to the chief executive officer and the four other most
highly compensated officers of a public company. Certain types of  compensation,
including  performance-based  compensation,  are  excluded  from  this deduction
limit. In an effort to  ensure that compensation payable  under the MIC Plan  to
certain  executives  will  qualify  as  performance-based  compensation  that is
generally tax-deductible, the MIC Plan is being submitted to shareholders of NSP
and WEC for approval at the NSP Meeting and the WEC Meeting, respectively. While
Primergy believes  compensation  payable  pursuant  to  the  MIC  Plan  will  be
deductible  for  federal income  tax  purposes under  most  circumstances, final
regulations have not yet been promulgated  under Section 162(m) of the Code  and
there  can be no assurance in this regard. Moreover, under certain circumstances
such as death,  disability and  change in  control (all  as defined  in the  MIC
Plan),  compensation  not qualified  under  Section 162(m)  of  the Code  may be
payable. By approving the  MIC Plan, the shareholders  will be approving,  among
other  things,  the performance  measures,  eligibility requirements  and annual
incentive award limits contained therein. The affirmative vote of a majority  of
the  votes entitled to be cast by the  holders of the shares of NSP Common Stock
and NSP Preferred Stock,  on the one  hand, and WEC Common  Stock, on the  other
hand,  represented at  the NSP  Meeting and  the WEC  Meeting, respectively, and
entitled to vote thereon (PROVIDED THAT, in the case of the vote required at the
NSP Meeting, the total vote cast represents over 50% of the voting power of  all
the shares of NSP Common Stock and NSP Preferred Stock entitled to vote thereon)
is required to approve the MIC Plan. THE BOARDS OF DIRECTORS OF NSP AND WEC EACH
UNANIMOUSLY RECOMMEND A VOTE FOR APPROVAL OF THE MIC PLAN.

    Set  forth below is a summary of certain important features of the MIC Plan,
which summary  is qualified  in its  entirety by  reference to  the actual  plan
attached as Annex L to this Joint Proxy Statement/Prospectus:

        ADMINISTRATION.    The MIC  Plan will  be  administered by  the Primergy
    Compensation Committee, or such other committee of the Primergy Board as the
    Primergy Board may from time to  time designate, which, unless the  Primergy
    Board determines otherwise, will be composed solely

                                       99
<PAGE>
    of  not  less  than  two "disinterested  persons"  who  qualify  as "outside
    directors" for  purposes  of  Section  162(m)  of  the  Code.  The  Primergy
    Compensation   Committee  will  have  sole   authority  to  make  rules  and
    regulations relating  to  the  administration  of  the  MIC  Plan,  and  any
    interpretations  and decisions  of the Primergy  Compensation Committee with
    respect to the MIC Plan will be final and binding.

        ELIGIBILITY.   The Primergy  Compensation Committee  will, in  its  sole
    discretion,  determine those officers and salaried employees of Primergy who
    shall be eligible to participate  in the MIC Plan for  a given period of  12
    months  or less (an "Incentive Period"). These participants will be selected
    based upon  their opportunity  to have  a substantial  impact on  Primergy's
    results.  Participation  in the  MIC Plan  by a  participant during  a given
    Incentive  Period  does   not  require  continued   participation  by   such
    participant in any subsequent Incentive Period. The initial determination of
    persons eligible to participate in the MIC Plan will not be made until after
    the   Effective  Time  by  the   Primergy  Compensation  Committee  as  then
    constituted. Accordingly, it is  not possible to estimate  at this time  the
    number of persons who will be eligible to participate in the MIC Plan.

        PLAN  FEATURES.  The MIC Plan provides for the payment of cash incentive
    awards to participants  designated by the  Primergy Compensation  Committee,
    which  payments may  be conditioned  upon the  attainment of pre-established
    performance goals or  upon such other  factors or criteria  as the  Primergy
    Compensation  Committee  shall  determine.  Such  performance  goals  may be
    different for each participant. Bonus amounts are determined by  multiplying
    a  participant's  "Target  Incentive  Award" by  a  percentage  which varies
    depending on the extent to which  the performance goals or other factors  or
    criteria  are satisfied. A participant's Target Incentive Award, in turn, is
    determined by multiplying such participant's base salary as of the last  day
    of  the  applicable  Incentive  Period by  a  percentage  designated  by the
    Primergy Compensation Committee,  in its sole  discretion, which  percentage
    need  not be the same for each  participant (and which may exceed 100%). The
    Primergy Compensation Committee  may, in  its sole  discretion, increase  or
    decrease  the amount  of any incentive  awards payable to  a participant and
    may, in recognition of special  circumstances, pay incentive awards even  if
    not  earned,  PROVIDED  that  the  Primergy  Compensation  Committee  cannot
    increase the amount of  any incentive awards  payable to certain  designated
    "Covered  Employees." Incentive awards payable under the MIC Plan to certain
    designated "Covered Employees" are subject to special restrictions described
    in the following section.

        DESIGNATED COVERED EMPLOYEES.  The Primergy Compensation Committee  will
    have   the  authority,  in   its  sole  discretion,   to  designate  certain
    participants as "Covered  Employees" for a  specified Incentive Period  upon
    determining  that  such  participants are  or  are expected  to  be "covered
    employees" within  the  meaning of  Section  162(m)  of the  Code  for  such
    Incentive Period. Not more than 90 days after the beginning of the Incentive
    Period,  and, in any event,  before 25% or more  of the Incentive Period has
    elapsed, the Primergy Compensation Committee will establish the  performance
    goals  for the  bonus award opportunities  of these  Covered Employees. Such
    performance goals  are to  be comprised  of  one or  more of  the  following
    measures:  earnings per share, market share,  stock price, sales, costs, net
    operating income, cash flow, retained earnings, return on equity, results of
    customer satisfaction  surveys, aggregate  product price  and other  product
    price  measures, safety record,  service reliability, demand-side management
    (including conservation and load management), operating and maintenance cost
    management,  energy  production  availability,  and  individual  performance
    measures.  Such performance  goals also  may be  based on  the attainment of
    specified levels  of  performance by  Primergy  under  one or  more  of  the
    measures  described above relative to the performance of other corporations.
    With respect to Covered Employees,  all Performance Goals must be  objective
    performance   goals  satisfying  the   requirements  for  "performance-based
    compensation" within the meaning  of Section 162(m)  of the Code.  Incentive
    awards  payable to Covered Employees are to be calculated in the same manner
    described in the "--  Plan Features" section  above, except that  subjective
    individual

                                      100
<PAGE>
    performance  ratings  cannot be  used to  increase  the amount  of incentive
    awards payable to  Covered Employees. No  incentive awards will  be paid  to
    Covered  Employees  if  the minimum  applicable  pre-established Performance
    Goals are  not  satisfied,  unless  the  Covered  Employee's  employment  is
    terminated because of death, disability or a change of control. Furthermore,
    the Primergy Compensation Committee will have the authority to decrease, but
    not to increase, the amount of incentive awards otherwise payable to Covered
    Employees   pursuant  to  pre-established   performance  goals  and  payment
    formulas. The maximum amount payable to any Covered Employee for any  fiscal
    year of Primergy will be $1,000,000.

        AMENDMENT AND DISCONTINUANCE.  The Primergy Board will have the right to
    amend,  alter, discontinue  or otherwise  modify the  MIC Plan  from time to
    time, but  no  amendment  will,  without  the  consent  of  the  participant
    affected,  impair  any  award  made  prior  to  the  effective  date  of the
    modification.

        NEW PLAN BENEFITS.  It cannot  be determined at this time what  benefits
    or  amounts, if any, will be received by or allocated to any person or group
    of persons under the MIC Plan if the MIC Plan is adopted or what benefits or
    amounts would have been received by or  allocated to any person or group  of
    persons for the last fiscal year if the MIC Plan had been in effect.

          UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL INFORMATION

    The  following  unaudited  pro  forma  financial  information  combines  the
historical consolidated balance sheets and statements of income of NSP and  WEC,
including their respective subsidiaries, after giving effect to the Mergers. The
unaudited  pro forma  combined condensed  balance sheet  at June  30, 1995 gives
effect to the Mergers as  if they had occurred at  June 30, 1995. The  unaudited
pro forma combined condensed statements of income for each of the three years in
the  period ended December 31,  1994, the six-month periods  ended June 30, 1995
and 1994,  and the  12-month period  ended June  30, 1995,  give effect  to  the
Mergers  as  if they  had  occurred at  January  1, 1992.  These  statements are
prepared on the basis of  accounting for the Mergers  as a pooling of  interests
and are based on the assumptions set forth in the notes thereto.

    The  WEC income statements for the six-month  period ended June 30, 1994 and
the fiscal year ended  December 31, 1994 include  a significant one-time  pretax
charge  of $73,900,000 for revitalization costs recorded in the first quarter of
1994. To  provide  a  more representative  recent  12-month  period  summarizing
combined  operating results, a pro forma  combined condensed statement of income
for the 12-month period ended June 30, 1995 is also presented.

    The following pro forma  financial information has  been prepared from,  and
should  be  read  in  conjunction with,  the  historical  consolidated financial
statements and related notes thereto of  NSP and WEC, incorporated by  reference
herein. The following information is not necessarily indicative of the financial
position  or operating  results that  would have  occurred had  the Mergers been
consummated on the  date, or  at the  beginning of  the periods,  for which  the
Mergers  are  being given  effect  nor is  it  necessarily indicative  of future
operating results or financial position.

      NOTES TO UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS

1.  The pro forma combined condensed financial statements reflect the conversion
    of  each share of NSP Common Stock  ($2.50 par value) outstanding into 1.626
    shares of Primergy  Common Stock ($.01  par value) and  the continuation  of
    each  share of WEC Common Stock ($.01 par value) outstanding as one share of
    Primergy Common Stock, as  provided in the Merger  Agreement. The pro  forma
    combined  condensed financial statements  are presented as  if the companies
    were combined during all periods included therein.

2.  The allocation between NSP and WEC and their customers of the estimated cost
    savings resulting from  the Mergers, net  of the costs  incurred to  achieve
    such savings, will be subject to regulatory review and approval. Transaction
    costs  are currently  estimated to  be approximately  $30,000,000 (including
    fees for financial  advisors, attorneys,  accountants, consultants,  filings
    and  printing). None of  these estimated cost savings,  the costs to achieve
    such savings, or  transaction costs  have been  reflected in  the pro  forma
    combined condensed financial statements.

3.     Intercompany  transactions  (including   purchased  and  exchanged  power
    transactions) between  NSP and  WEC during  the periods  presented were  not
    material  and, accordingly, no pro forma  adjustments were made to eliminate
    such transactions.

4.   A  pro forma  adjustment  has been  made  to conform  the  presentation  of
    noncurrent deferred income taxes in the pro forma combined condensed balance
    sheet  into one net  amount. All other  financial statement presentation and
    accounting policy differences are immaterial  and have not been adjusted  in
    the pro forma combined condensed financial statements.

                  SELECTED INFORMATION CONCERNING WEC AND NSP

BUSINESS OF WEC

    WEC,  headquartered  in Milwaukee,  Wisconsin,  is a  holding  company whose
principal subsidiaries are  WEPCO and  Wisconsin Natural. WEC  also has  certain
non-utility  subsidiaries.  WEPCO  generates, transmits,  distributes  and sells
electric energy  in a  territory of  approximately 12,000  square miles  with  a
population  estimated at over 2,200,000 in southeastern (including the Milwaukee
area), east  central  and northern  Wisconsin  and  in the  Upper  Peninsula  of
Michigan. WEPCO also distributes and sells steam to space heating and processing
customers  in downtown and near south side Milwaukee, Wisconsin. At December 31,
1994,  WEPCO  had  approximately  945,000  electric  customers  and  470   steam
customers.  Wisconsin Natural  purchases, distributes  and sells  natural gas to
retail customers and  transports customer-owned  gas in  three distinct  service
areas  in Wisconsin: west and south of the City of Milwaukee; the Appleton area;
and the Prairie du Chien area. Wisconsin Natural's gas service territory has  an
estimated  population  of  over 1,100,000  and  is largely  within  the electric
service area  of  WEPCO.  At  December  31,  1994,  Wisconsin  Natural  serviced
approximately  350,000  customers.  WEC's non-utility  subsidiaries  are devoted
primarily to stimulating economic growth  in the utilities' service  territories
and   to   capitalizing  on   diversified   investment  opportunities   for  WEC
shareholders. Additional  information concerning  WEC  and its  subsidiaries  is
included  in the  WEC documents  filed with  the SEC  which are  incorporated by
reference herein. See "Incorporation by Reference."

    Information regarding the names,  ages, positions, and business  backgrounds
of  the  executive  officers  and  directors  of  WEC,  as  well  as  additional
information, including  executive compensation,  security ownership  of  certain
beneficial   owners  and  management  and   certain  relationships  and  related
transactions, is incorporated by reference to Items  10, 11, 12 and 13 of  WEC's
Annual  Report  on  Form  10-K  for the  year  ended  December  31,  1994 (which
incorporates portions of WEC's definitive Proxy Statement for its Annual Meeting
of Stockholders held on May 17, 1995). In connection with the submission of  the
Primergy  Plans  for shareholder  approval,  certain information  concerning the
compensation of  executive officers  and  directors of  WEC is  included  herein
immediately below.

WEC EXECUTIVE COMPENSATION

    COMPENSATION OF THE WEC BOARD OF DIRECTORS

    During  1994, each nonemployee  director of WEC  received a monthly retainer
fee of $1,500 plus $1,000 for each  WEC Board or committee meeting attended.  In
addition,  a PER DIEM fee  of $1,000 for travel on  company business is paid for
each day on which a WEC Board or committee meeting is not also held. Nonemployee
directors are also paid $300 for each signed, written unanimous consent in  lieu
of  a meeting. Effective with  the date of the  1994 Annual Meeting, nonemployee
chairs of the committees of the  WEC Board received a quarterly committee  chair
retainer  of $1,250. Although certain WEC  directors also serve on WEPCO's Board
of Directors and compensation committee, only single fees are paid for  meetings
held  by both  boards or committees  on the same  day. In these  cases, fees are
allocated  between  WEC  and  WEPCO  based  on  services  rendered.  Nonemployee
directors  may defer fees so long as they serve on the Board of Directors of WEC
and/or its subsidiaries pursuant to  an established plan which accrues  interest
semiannually  at the prime  rate on the  amounts which have  been deferred. Such
deferral amounts  are credited  to an  unsecured  account in  the name  of  each
participating  director  on the  books  of WEC  and  are payable  only following
termination of the director's service to WEC and its subsidiaries. Such  amounts
will  be paid out of the general corporate assets or the grantor trust described
under "-- Retirement Plans." Employee directors receive no directors' fees.

(1)  Consists of incentive and non-qualified stock options to purchase shares of
     WEC  Common Stock granted pursuant to the 1993 Omnibus Stock Incentive Plan
     (the "OSIP") on December 14, 1994. These options were granted with an equal
     number of contingent dividend  awards (as described  in the table  entitled
     "Long-Term  Incentive Plans -- Awards in  Last Fiscal Year"), have exercise
     prices equal to  the fair market  value of the  WEC shares on  the date  of
     grant and first become exercisable on December 14, 1998, at which time they
     become  fully exercisable. Upon a "change in control" of WEC (as defined in
     the OSIP; see " -- Mergers  Not Intended to Constitute Change In  Control")
     or  upon  retirement, permanent  total disability  or  death of  the option
     holder, these options shall  become immediately exercisable. These  options
     were  granted for  a term  of 10 years,  subject to  earlier termination in
     certain events related to termination  of employment. In the discretion  of
     the  Compensation Committee of the WEC Board (the "WEC Compensation Commit-
     tee"), the exercise price may be  paid by delivery of already owned  shares
     and  tax withholding  obligations related to  exercise may  be satisfied by
     withholding shares otherwise deliverable upon exercise, subject to  certain
     conditions.  Subject to the  limitations of the  OSIP, the WEC Compensation
     Committee has the power with the  participant's consent to modify or  waive
     the restrictions on vesting of these options, to amend these options and to
     grant extensions or to accelerate these options.

(2)  The  dollar amounts in these columns are  the result of calculations at the
     5% and 10% stock  appreciation rates set  by the SEC  and therefore do  not
     forecast possible future appreciation, if any, of WEC's Common Stock price.
     At  the December 13, 2004  expiration date of the  options granted in 1994,
     the price of  a share of  WEC Common Stock  would be $43.68  at an  assumed
     annual appreciation rate of 5% and $69.55 at an assumed annual appreciation
     rate  of 10%. Gains to all shareholders of record at year-end 1994 at those
     assumed annual appreciation rates would  be approximately $1.8 billion  and
     $4.7  billion, respectively. The total "Potential Realizable Value" for the
     named executive officers would represent approximately .03% of such gains.
</TABLE>

No stock options other than those granted pursuant to the OSIP were  outstanding
in  the last fiscal year. Since the earliest date outstanding options previously
granted under the OSIP become exercisable is December 15, 1997, no options  were
exercisable  in 1994. The following table sets forth the number of options which
were not exercisable  and the value  of such options  based upon the  difference
between  the exercise price and the market  price of the underlying shares as of
December 31, 1994.

     stock  options (as  described in the  table entitled  "Option/SAR Grants in
     Last Fiscal  Year").  These performance  units,  entirely in  the  form  of
     contingent   dividends,   will  be   paid   if  total   shareholder  return
     (appreciation in the value of  WEC Common Stock plus reinvested  dividends)
     over  a four-year  period ending  December 13,  1998 equals  or exceeds the
     median return earned by the companies  included in the Peer Group Index  in
     the "Performance Graph" section of WEC's definitive Proxy Statement for its
     Annual Meeting of Stockholders held on May 17, 1995, except that there will
     be  no payout if WEC's total shareholder return is negative over the course
     of such period. If payable, each participant shall receive an amount  equal
     to the actual dividends paid on WEC Common Stock for the period of December
     14,  1994 through December 13, 1998 multiplied by the number of performance
     units awarded to such  participant. Upon a "change  in control" of WEC,  as
     defined  in  the  OSIP,  this  benefit  shall  immediately  vest  with  all
     performance goals deemed fully achieved.

    RETIREMENT PLANS

    WEC's utility subsidiaries maintain separate retirement plans for management
employees,  including executive officers. WEC  executive officers participate in
the WEPCO  management employee  retirement plan.  The plans  provide  retirement
income   based  upon  years  of  credited   service  and  final  average  annual
compensation for the 36  highest consecutive months.  The following table  shows
the  estimated annual  pension benefits  payable upon  retirement to  persons in
various compensation  and  years-of-service classifications  (including  amounts
attributable   to  the  Supplemental  Executive  Retirement  Plan  (the  "SERP")
described below that would  otherwise be payable  under the management  employee
retirement  plan if the  pension benefits were calculated  without regard to any
Code limitation on pension benefits or covered compensation):

    The  compensation  for   the  individuals  listed   in  the  above   Summary
Compensation  Table  in the  columns labeled  "Salary",  "Bonus" and  "All Other
Compensation"  is  virtually  equivalent  to  the  compensation  considered  for
purposes  of the  retirement plans and  the various  supplemental plans. Messrs.
Abdoo, Boston, Remmel, Porter and Brzezinski currently have 19, 12, 39, 25 and 5
credited years of  service, respectively.  Credited years of  service under  the
retirement plans for certain individuals may be fewer than years of service with
the  companies  as reported  in the  annual  report to  stockholders. Retirement
benefits are not subject  to any deduction for  Social Security or other  offset
since  they  are computed  using  a step-rate  formula  which provides  a Social
Security integrated  benefit  based  upon  percentages of  the  average  of  the
participant's  highest 36 consecutive months of  compensation for up to 30 years
of credited  service  with additional  (lower)  percentages of  compensation  in
excess  of 30  years up  to a maximum  of 10  years. The  SERP (described below)
provides designated participants a "make whole" benefit equal to any decrease in
pension which may have resulted when the retirement plans adopted the  step-rate
formula.  Such "make whole" benefit will be  paid as a pension supplement out of
the general corporate assets or the grantor trust described below.

    Designated elected officers of WEC and the utility subsidiaries  participate
in  the  SERP.  The  SERP  provides  monthly  supplemental  pension  benefits to
participants, which will be  paid out of corporate  assets or the grantor  trust
described  below as follows: (a)  an amount equal to  the difference between the
actual pension benefit payable under the management employee retirement plan and
what such  pension  benefit  would  be  if  calculated  without  regard  to  any
limitation  imposed by the Code on pension benefits or covered compensation, (b)
an amount calculated so as to provide participants with a supplemental  lifetime
annuity, estimated to amount to between 8% and 10% of final average compensation
depending  on which pension  payment option is  selected, and (c)  an amount for
certain participants equal to the difference between the actual pension  benefit
payable  under the  management employee  retirement plan  and what  such pension
benefit would be if calculated under the prior

benefit formula in effect on December 31, 1988. Except for a "change in control"
of WEC (as  defined in the  SERP; see "  -- Mergers Not  Intended to  Constitute
Change  In Control")  no such  payments are made  until after  the retirement or
death of the participant.

    WEC has entered into agreements with Mr. Abdoo and Mr. Boston, each of  whom
could  not accumulate by  normal retirement age  the maximum number  of years of
credited service under  the management employee  retirement plans. According  to
these   agreements,  Messrs.  Abdoo  and   Boston  at  retirement  will  receive
supplemental retirement payments which will make their total retirement benefits
at age 58, in the case of Mr. Abdoo,  and at age 60, in the case of Mr.  Boston,
or  older substantially the  same as those  payable to employees  who are in the
same compensation bracket and who became plan participants at the age of 25. Mr.
Boston retired from all positions held as an officer and director of WEC and its
subsidiaries,  effective  July  1,  1995,  at  age  62.  On  October  27,  1993,
resolutions  were adopted authorizing  amendments to these  agreements, the SERP
and the Executive Deferred Compensation Plan  to provide for establishment of  a
grantor trust to fund such agreements and plans and to provide for optional lump
sum  payments and, in  the instance of  a change in  control, mandatory lump sum
payouts without regard to whether the executive's employment has terminated.  In
each  case, the  interest rate  benchmark formula  for calculating  the lump sum
amount is the five-year U.S. Treasury Note yield as of the last business day  of
the  month prior to the  date of payment. The  WEC Executive Non-Qualified Trust
has been established and funded for this purpose.

    MERGERS NOT INTENDED TO CONSTITUTE CHANGE IN CONTROL

    See "The Mergers -- Primergy Plans -- Actions with Respect to Existing Stock
Options and  Certain Other  Existing Arrangements"  for a  description of  WEC's
agreement  to amend each of the  WEC compensation arrangements containing change
in control  provisions so  that such  provisions will  not be  triggered by  the
Mergers.  For purposes  of these provisions,  "change in control"  is defined to
mean the  occurrence  of  any of  the  following  events, as  a  result  of  one
transaction  or a series of transactions: (a) any "person" (as such term is used
in Sections  13(d)  and  14(d) of  the  Exchange  Act, but  excluding  WEC,  its
affiliates  and any  qualified or  non-qualified plan  maintained by  WEC or its
affiliates) becomes the "beneficial owner" (as defined in Rule 13d-3 promulgated

    WEC COMPENSATION COMMITTEE

    The directors who served as members of the WEC Compensation Committee during
the  fiscal year ended  December 31, 1994  were Morris W.  Reid (chair), John F.
Ahearne, John F. Bergstrom, Robert A. Cornog, Geneva B. Johnson, John L. Murray,
Frederick P. Stratton, Jr. and Jon G. Udell.

BUSINESS OF NSP

    NSP is predominantly an operating public utility engaged in the  generation,
transmission  and distribution of electricity  and the transportation of natural
gas in  Minnesota,  North  Dakota  and  South  Dakota.  NSP's  most  significant
subsidiary,  NSP-Wisconsin,  also  is  an operating  public  utility  and serves
customers in Wisconsin and  the Upper Peninsula of  Michigan. Together, NSP  and
NSP-Wisconsin  serve  a  49,000  square  mile  service  area  with  a population
estimated at approximately 3,000,000, of which the majority are concentrated  in
the  Minneapolis-St. Paul metropolitan  area. At December 31,  1994, NSP and its
subsidiaries   served   approximately    1,380,000   electric   customers    and

                                      117
<PAGE>
400,000  gas customers. For the year  ended December 31, 1994, approximately 83%
of NSP and NSP-Wisconsin's  gross utility operating  revenues were derived  from
electricity  and  17%  from gas.  NSP's  other  utility business  is  Viking Gas
Transmission Company, which owns and operates a 500-mile interstate natural  gas
pipeline serving portions of Minnesota, Wisconsin and North Dakota.

    In addition to its utility businesses, NSP, through various subsidiaries, is
engaged  in  non-utility  businesses.  NRG, a  wholly-owned  subsidiary  of NSP,
builds, acquires,  owns and  operates, either  directly or  indirectly,  through
subsidiaries,  certain energy-related businesses. Among these businesses are the
ownership of a 33% interest in the coal mining, power generation and  associated
operations of Mitteldeutsche Braunkohlengesellschaft mbH (MIBRAG), located south
of Leipzig, Germany and the ownership of a 37.5% interest in the Gladstone Power
Station,  a 1680 Mw coal-fired plant  in Gladstone, Queensland, Australia, which
NRG's Australian subsidiary also operates.

    NSP's other non-utility  subsidiaries include Cenergy,  Inc., a natural  gas
marketing  company that  also has  recently received  approval from  the FERC to
market electricity, and  Eloigne Company,  which invests  in affordable  housing
projects that qualify for low-income housing tax credits under federal tax law.

    NSP  is an exempt holding company by  order of the SEC under Section 3(a)(2)
of the 1935 Act and, accordingly, is exempt from the provisions of the 1935 Act,
other than  with respect  to  certain acquisitions  of  securities of  a  public
utility.

    Additional information concerning NSP is included in the NSP documents filed
with  the SEC which are incorporated  by reference herein. See "Incorporation by
Reference."

    For NSP shareholders, information regarding  the names, ages, positions  and
business  backgrounds of the executive officers and directors of NSP, as well as
additional information, including executive compensation, security ownership  of
certain  beneficial owners and management  and certain relationships and related
transactions, is incorporated by reference to Items 10, 11, 12 and 13 of the NSP
Annual Report on Form 10-K for the year ended December 31, 1994. Certain of such
information is also  set forth below  under "Election of  NSP Directors",  which
section  is included only in the  Joint Proxy Statement/Prospectus being sent to
NSP shareholders.

CERTAIN BUSINESS RELATIONSHIPS BETWEEN WEC AND NSP

    In the normal course of business, NSP and WEPCO buy and sell electric  power
from  and  to each  other in  arm's-length transactions  pursuant to  filed rate
schedules. From time to time over the last several years, executive officers  of
WEPCO  and NSP have discussed possible business relationships. Most recently, in
September 1993, NSP, WEPCO  and Wisconsin Public  Service Corporation, a  public
utility  headquartered in Green Bay,  Wisconsin ("WPSC"), agreed to collectively
evaluate the feasibility  of, and  potential savings  in, forming  a company  to
provide  operating  services to  WEPCO's,  NSP's and  WPSC's  nuclear generating
plants. This evaluation identified and assessed the economies of scale and other
operational synergies that  could be obtained  as a result  of such venture.  By
late  summer 1994, it was  apparent that such an  operating company would not be
feasible  because  of  considerations   concerning  ownership,  governance   and
licensing.

                         PRIMERGY FOLLOWING THE MERGERS

    No  later than the  Effective Time, subject  to approval of  the Name Change
Amendment  at  the  WEC  Meeting,  WEC   will  change  its  name  to   "Primergy
Corporation."  Primergy will  be the  parent of both  New NSP  and the operating
subsidiaries of  WEC.  The headquarters  of  Primergy will  be  in  Minneapolis,
Minnesota.  The  utility  subsidiaries  of  Primergy  will  serve  approximately
2,300,000 electric customers and 750,000 natural gas customers, and its  service
territory  will include  portions of  Minnesota, Wisconsin,  North Dakota, South
Dakota and  the Upper  Peninsula  of Michigan.  The  business of  Primergy  will
consist  of owning utilities  and various non-utility  subsidiaries. NSP and WEC
recognize that  the divestiture  of their  existing gas  operations and  certain
non-utility operations is a possibility under the new registered holding company
structure,  but are seeking  approval from the SEC  to maintain such businesses.
See "Regulatory Matters."

                                      118
<PAGE>
MANAGEMENT OF PRIMERGY

    Pursuant to the Merger Agreement, at the Effective Time, the Primergy  Board
will  consist of 12 members, six members of  which will be designated by WEC and
six members  of  which  will  be  designated by  NSP.  It  is  anticipated  that
simultaneously with the Mergers, all but six of the WEC directors then in office
will  resign  and the  remaining WEC  directors  will increase  the size  of the
Primergy Board to 12 and appoint the six persons designated by the NSP Board  to
fill the six resulting vacancies. To date, NSP and WEC have not determined which
individuals,  in addition  to Messrs.  Howard and  Abdoo, will  be designated to
serve as directors of Primergy as of the Effective Time. The initial designation
of such directors among the three classes of the Primergy Board shall be  agreed
to  by NSP and WEC, the designees of each party to be divided equally among such
classes. Each designee shall serve for a term equal to the remaining balance  of
the  three-year term  of the  class of  directors in  which such  designee shall
serve. At each annual shareholders' meeting after the Effective Time, the number
of directors equal to the number of the class whose term expires at the time  of
the  meeting  shall  be elected  for  a term  of  three years.  See  "The Merger
Agreement -- Primergy Board of Directors."

    Mr. Howard will be Chairman and Chief Executive Officer of Primergy and  Mr.
Abdoo  will be Vice Chairman, President and Chief Operating Officer of Primergy.
Each of Mr. Howard and Mr. Abdoo will have an employment agreement with Primergy
following the Mergers. See "The Mergers -- Employment Agreements."

OPERATIONS

    After the Mergers,  New NSP (which  will be renamed  "Northern States  Power
Company")  and WEPCO  (which will  be renamed  "Wisconsin Energy  Company") will
continue to operate as the principal subsidiaries of Primergy. It is anticipated
that Wisconsin  Natural  will  be merged  into  WEPCO  by January  1,  1996,  as
previously  planned, and  following the  Mergers, NSP-Wisconsin  will merge into
Wisconsin Energy Company. The headquarters of  the two utilities will remain  in
their  current  locations, Northern  States Power  Company's in  Minneapolis and
Wisconsin Energy Company's in Milwaukee.

    Upon receipt of the  necessary approval from  the FERC and  on or after  the
Effective  Time, Wisconsin Energy Company  and New NSP will  become parties to a
Coordination Agreement, whereby  costs of generating  capacity and  transmission
are  shared in a  manner similar to the  existing coordination agreement between
NSP and NSP-Wisconsin. The integration of  the Wisconsin Energy Company and  New
NSP  generating capacity should increase the  ability of these companies to meet
demands  for  electricity  within  the  territories  each  serves.  It  is  also
anticipated  that a single administrative and support system will be established
following the Mergers.

    The non-utility  operations  of WEC  are  presently conducted  through  five
wholly-owned  subsidiaries.  The  non-utility operations  of  NSP  are conducted
primarily through NRG, Cenergy, Inc. and Eloigne Company. Following the Mergers,
it is  anticipated  that  New  NSP  will  transfer  its  non-utility  businesses
(including   Viking  Gas  Transmission  Company)   to  Primergy  and  that  such
non-utility businesses of New NSP, along with the non-utility businesses of WEC,
will be conducted  through one  or more subsidiaries  of Primergy  that are  not
subsidiaries  of New NSP or Wisconsin Energy Company. If, as is anticipated, all
of such  subsidiaries are  transferred, New  NSP will  consist of  the  existing
electric  and gas utility operations conducted directly by NSP, as a stand-alone
entity. Reference is made to  the NSP Form 10-Q for  the quarter ended June  30,
1995,  as  amended, and  the NSP  Form 8-K  dated June  27, 1995,  which present
certain pro forma financial  information of New NSP  after giving effect to  the
Mergers,  the anticipated merger of  NSP-Wisconsin into Wisconsin Energy Company
and the  anticipated  transfer by  New  NSP  of its  non-utility  businesses  to
Primergy.

    Pursuant  to  the  Merger  Agreement,  Primergy  shall  continue  to provide
charitable contributions and community support  within the service areas of  WEC
(including  the former  service area  of NSP-Wisconsin)  and NSP,  at comparable
levels to those provided by such parties within the two-year period prior to the
Effective Time.

                                      119
<PAGE>
DIVIDENDS

    It is  anticipated that  Primergy  will adopt  NSP's common  share  dividend
payment  level  adjusted  for the  Ratio.  NSP  currently pays  $2.70  per share
annually, and WEC's annual dividend rate is currently $1.47 per share. Based  on
the  Ratio and  NSP's current  dividend rate,  the pro  forma dividend  rate for
Primergy would be $1.66 per share. However, no assurance can be given that  such
dividend  rate will be in effect or will remain unchanged, and Primergy reserves
the right to  increase or decrease  its dividend as  may be required  by law  or
contract or as may be determined by the Primergy Board, in its discretion, to be
advisable.  Declaration and timing of dividends on Primergy Common Stock will be
a business decision to  be made by  the Primergy Board from  time to time  based
upon  the  results of  operations and  financial condition  of Primergy  and its
subsidiaries and  such  other  business considerations  as  the  Primergy  Board
considers  relevant in  accordance with  applicable laws.  For a  description of
certain restrictions  on Primergy's  ability to  pay dividends  on the  Primergy
Common Stock, see "Description of Primergy Capital Stock."

meeting in 1996  will be mailed  on or about  April 24, 1996.  Therefore, to  be
included  in the proxy statement for the  1996 annual meeting of shareholders of
NSP, a proposal by a shareholder for the NSP annual shareholder meeting in  1996
must  be received  by the  Secretary of NSP  at 414  Nicollet Mall, Minneapolis,

<PAGE>
    Any proposal by a shareholder for the WEC annual shareholder meeting in 1996

the proposals are proper for consideration at an annual meeting and are required
for  inclusion in the proxy statement by, and  conform to, the rules of the SEC.
For a proposal not included in the proxy statement to be properly brought before
an annual meeting by a shareholder,  the WEC Bylaws provide that written  notice
of  such proposal must be delivered personally  or sent by certified mail to the
Secretary of WEC  not less  than 70 days  nor more  than 100 days  prior to  the
meeting. The notice must contain (i) the name and address of the shareholder who
intends  to make the proposal;  (ii) a representation that  the shareholder is a
holder of record of the stock of the corporation entitled to vote at the meeting

rules  are applicable). The WEC Bylaws state that such a notice of a shareholder
proposal must be provided to  WEC a reasonable period  of time before a  special

                           ELECTION OF NSP DIRECTORS

GENERAL INFORMATION

    NSP's Bylaws provide that the NSP Board shall consist of at least 12, but no
more than 15 directors, as determined by the NSP Board. The NSP Board is divided
into three classes as nearly equal in number as possible with staggered terms of
office so that one class of directors will be elected at each annual meeting for
a term of three years.

    At  the NSP Meeting of NSP  Shareholders, the following four individuals are
the nominees to be elected to the NSP Board to serve in Class III until the 1998
Annual Meeting of Shareholders and until  their successors are elected and  have
qualified:  H.  Lyman  Bretting, David  A.  Christensen, Allen  F.  Jacobson and
Margaret R. Preska.  Each of these  individuals is currently  a director of  NSP
whose term is scheduled to expire at the NSP Meeting.

    All  of  the nominees  have  indicated a  willingness  to serve  if elected.
However, should any of the nominees  named above become unavailable, your  proxy
will  be voted  for such person  or persons as  shall be recommended  by a proxy
committee appointed by the NSP Board.

    Shareholders  are  entitled  to  vote  cumulatively  for  the  election   of
directors.  Each shareholder is entitled to a  number of votes for such election
equal to the number of shares held by such shareholder multiplied by the  number
of directors to be elected, and may cast all votes for one nominee or distribute
the votes among the nominees.

    The  election of  each director  shall be  decided by  plurality vote.  As a
result, any shares not voted for  a director (whether by withholding  authority,
broker non-vote or otherwise) have no impact on the election of directors except
to  the  extent  the  failure  to vote  for  an  individual  results  in another
individual receiving a larger number of votes.

    THE NSP BOARD UNANIMOUSLY RECOMMENDS THAT  YOU VOTE FOR ALL OF THE  NOMINEES
NAMED BELOW.

    The following information is furnished with respect to each nominee:

     the performance period ending September 30, 1994. As of December 31,  1994,
     the  named executives held  the following as  a result of  grants under the
     LTIP: Mr.  Howard  held  3,097  restricted shares  at  a  market  value  of
     $136,268;  Mr. McIntyre  held 854  restricted shares  at a  market value of
     $37,576; Mr.  Antony  held 413  restricted  shares  at a  market  value  of
     $18,172;  Mr.  Taylor  held 454  restricted  shares  at a  market  value of
     $19,976, Mr.  Johnson held  680  restricted shares  at  a market  value  of
     $29,957  and Mr. Theisen did not hold any restricted shares. The restricted
     stock awards vest one year after the  date of grant with respect to 50%  of
     the  shares and  two years  after such date  with respect  to the remaining
     shares, conditioned upon  the continued  employment of  the recipient  with
     NSP. Non-preferential dividends are paid on the restricted shares.

     Mr.  Antony received an additional 2,200  shares of restricted stock during
     1994, which as of December 31, 1994,  had a market value of $96,800.  These
     additional  shares vest with respect to 50% of the shares if Mr. Antony has
     been continually employed by  NSP on October 26,  1996 and with respect  to
     the remainder of the shares if he has been continually employed with NSP on
     October 26, 1998.

     The  total number of restricted shares  awarded during the years 1992, 1993
     and 1994 are as follows: 7,191 shares for Mr. Howard, 1,910 shares for  Mr.
     McIntyre,  2,594 shares  for Mr. Antony,  982 shares for  Mr. Taylor, 1,473
     shares for Mr. Johnson and 3,671 for Mr. Theisen.

(7)  NSP had no LTIP payouts  in 1994 due to  the replacement, by the  Corporate
     Management  Committee  of  the  NSP  Board,  of  dividend  equivalent stock
     appreciation rights ("DESARs") formerly awarded under NSP's LTIP, in  favor
     of increased stock options and restricted stock levels.

(8)  This  column consists of  the following: $4,031 was  contributed by NSP for
     the ESOP  for Messrs.  Howard  and Theisen,  respectively, $3,807  for  Mr.
     McIntyre,  $2,297 for Messrs. Johnson  and Taylor, respectively, and $2,642
     for Mr. Antony;  (NSP's contribution  on behalf of  all ESOP  participants,
     including  the named executive officers, was equal to 1.3% of their covered
     compensation.); the  value to  each  named executive  of the  remainder  of
     insurance  premiums paid  under the Officer  Survivor Benefit  Plan by NSP:
     $2,320 for Mr. Howard, $227 for Mr. McIntyre, $476 for Mr. Johnson, $0  for
     Mr.  Taylor, $837 for Mr. Antony and $1,418 for Mr. Theisen; imputed income
     as a  result  of  life insurance  paid  by  NSP on  behalf  of  each  named
     executive:  $2,205  for Mr.  Howard, $341  for Mr.  McIntyre, $399  for Mr.
     Johnson, $369  for Mr.  Taylor, $440  for  Mr. Antony  and $1,826  for  Mr.
     Theisen;  NSP  matching  401(k) plan  contribution  of $500  to  each named
     executive; and, earnings accrued under  the NSP Deferred Compensation  Plan
     to  the  extent such  earnings  exceeded the  market  rate of  interest (as
     prescribed pursuant to the  SEC rules), which was  $1,563 for Mr.  McIntyre
     and none for all other named executives.

                     CORPORATE MANAGEMENT COMMITTEE REPORT
                           ON EXECUTIVE COMPENSATION

    CORPORATE MANAGEMENT  COMMITTEE.    The Corporate  Management  Committee  is
composed  entirely of outside directors of  NSP and makes recommendations to the
NSP Board  concerning total  compensation  for executive  officers of  NSP.  The
Corporate Management Committee is the sole administrator of the executive annual
and long-term incentive plans with full authority to establish and interpret the
terms of the plans and to make payment of the awards.

    COMPENSATION  STRATEGY.  NSP's  executive compensation goals  for 1994 were:
(i) to provide a  competitive compensation package that  enables NSP to  attract
and retain key executives and (ii) to align the executive's interests with those
of NSP's stockholders and with NSP's performance. The 1994 compensation of NSP's
executives  was comprised primarily of base  salary, annual incentive awards and
long-term incentive awards.

    To achieve the  compensation goal  of providing  a competitive  compensation
package,  the Corporate  Management Committee seeks  to set base  salary and the
target amounts of the annual  and long-term awards at  the median of a  combined
group  of major utilities and industrial companies (the "Peer Group"). For 1994,
the Peer Group consists of  ten industrial companies, with local  representation
and  average revenues of $2.6  billion, and ten utilities,  all of which operate
nuclear facilities,  with  average  revenues  of  $2.6  billion.  The  utilities
included  in  this group  are also  part  of the  Edison Electric  Institute 100
utilities index used in  the Total Shareholder Return  Comparison in this  proxy
statement,  but all of the companies in such  index are not included in the Peer
Group for purposes  of compensation  review. The  twenty companies  in the  Peer
Group  were selected primarily because they  are viewed as representative of the
types of companies with which NSP competes in attracting and retaining executive
officers.

    The annual  and  long-term  portions  of  an  executive's  compensation  are
intended  to achieve NSP's goal of  aligning an executive's interests with NSP's
shareholders  and  with  NSP  performance.  These  portions  of  an  executive's
compensation  are  placed  at risk  and  are  limited to  the  accomplishment of
specific results that are designed to  benefit NSP's stockholders and NSP,  both
in  the long and short term. As a result, during years of excellent performance,
executives  are  provided  the  opportunity  to  earn  a  competitive  level  of
compensation  and,  conversely,  in years  of  below-average  performance, their
compensation  would  be  below  competitive  levels.  Generally,  higher   level
executive officers have a greater level of compensation placed at risk.

    In  1993, a new federal tax law was passed which limits the deductibility of
executive compensation in  excess of  $1,000,000 unless  certain exceptions  are
met.  Under transition rules adopted by the IRS, this new law is not expected to
impact NSP with respect to executive compensation paid in 1995. The Committee is
reviewing the new law  and associated regulations, as  well as the structure  of
its  salary and various compensation programs, and its present intent is to take
appropriate steps  to  ensure  the  continued  deductibility  of  its  executive
compensation.

    BASE  PAY.  The level of base pay is not directly related to NSP's financial
performance. Instead,  target  levels for  base  pay are  established  for  each
executive  officer based on the  median base pay level  for that position within
the Peer Group. The target level of base pay is subject to some adjustment  (15%
either  way)  to reflect  individual  performance. Each  January,  the Corporate
Management Committee reviews officer  goals that describe achievements  expected
to  be  completed  during the  year  and subsequently  evaluates  each officer's
performance of his or her goals. Because 1993 salary levels were within targeted
pay levels of the Peer Group, there were no general base pay increases for 1994,
despite solid  individual  performances  of executive  officers,  including  Mr.
Howard.

    ANNUAL  INCENTIVE.  Annual  incentive awards for  the executive officers are
made in  accordance  with  NSP's  Executive  Incentive  Compensation  Plan  (the
"Plan").  Under the  Plan, annual incentive  awards are  established with target
awards (expressed  as  a  percentage  of  base  pay)  commensurate  with  annual
incentive awards for the position at the median level within the Peer Group. For
1994, target

                                      131
<PAGE>
                   [ALTERNATE PAGE FOR NSP SHAREHOLDERS ONLY]
awards  for  executive  officers ranged  from  20%  to 40%  of  their  base pay.
Individuals can realize from 0% to 188% of their target awards dependent on  the
performance  of  NSP,  the  individual and  the  individual's  group  in certain
pre-determined areas. These areas are NSP financial performance (based on  EPS),
customer  satisfaction,  service  reliability,  price  of  product,  safety  and
individual performance.  The awards  given  to the  CEO,  the President  --  NSP
Generation  and the Vice-President  -- Nuclear Generation  also are dependent on
performance specifically with  respect to  nuclear safety.  The weight  accorded
particular   performance  areas   varies  by   executive.  Generally,  financial
performance accounts for 20%-30% of  an executive's target incentive award.  All
of the other areas account for between 10% and 25% of the target awards. Because
of  NSP and individual performance, executives received from 21% to 62% of their
base pay for 1994. The  annual awards paid for 1994  are reflected in the  bonus
column of the Summary Compensation Table.

    Mr.  Howard's annual incentive award payout  for 1994 was $317,800, as shown
in the Summary Compensation Table. The determination of this amount was based on
the criteria set forth  above for the other  executive officers. In  particular,
Mr. Howard's target incentive award was 40% of his base pay and was based 25% on
financial  performance, 10%  on safety, 10%  on nuclear safety,  15% on customer
satisfaction, 15% on price of product, 15% on reliability and 10% on  individual
performance.

    LONG-TERM  INCENTIVE.  Long-term incentive awards for executive officers are
determined in accordance with  the LTIP and are  generally set at target  levels
commensurate  with the median level for the respective positions within the Peer
Group. The  LTIP  permits  the  granting  of  non-qualified  stock  options  and
restricted  common stock to  key employees. One of  the goals of  the LTIP is to
align key  employee's  long-term  interests with  those  of  NSP's  shareholders
through the use of stock ownership and long-term financial performance goals.

    The  Corporate Management Committee  made one grant  of stock options during
1994 to each of the named executive officers. Option grants are positioned at  a
level  which generally equates to the average grant levels awarded to executives
in comparable  positions in  the Peer  Group. The  number of  shares subject  to
option  was not  affected by  the number  of shares  previously awarded  to such
executives. These options were not exercisable until one year after their grant,
and will remain exercisable  for nine years. Stock  options are granted with  an
exercise  price of 100%  of the fair  market value of  the stock of  the date of
grant to ensure  that executives can  only be rewarded  for appreciation in  the
price of NSP's stock when NSP's stockholders are similarly benefited.

    Target awards of restricted stock (measured as a percentage of base pay) are
established  for  each executive  at levels  consistent  with median  levels for
comparable positions within the Peer Group.  In 1994, target awards ranged  from
25%  to 55% of the  executive's base pay. Restricted  stock is actually granted,
however, only  if NSP  achieves a  certain level  of financial  performance,  as
measured by NSP's return on common equity ("ROE") for the three year period then
ending,  as  compared to  the  three year  average  ROE of  the  Edison Electric
Institute 100 utilities ("EEI 100") index  (the same index used for purposes  of
comparing  shareholder return.) No restricted stock awards are made unless NSP's
three year average ROE  is at least equal  to the median of  the EEI 100  index,
thereby  prohibiting  restricted  stock  awards when  NSP  performance  does not
surpass the median performance of utilities in the Index. If NSP's ROE is .5% or
more above the index median, 100% of the target will be granted. Partial  payout
of  restricted stock  will be  made for  ROE levels  between the  median and .5%
above. In 1994, NSP's ROE was at the median, resulting in a payout of 75% of the
target. The stock awards are restricted so that 50% of the shares awarded become
available one year following the grant  and the remaining 50% becomes  available
after  two years. The  restricted stock awards reinforce  the tie to shareholder
returns, and the restrictions encourage the retention of qualified executives.

    In 1994, Mr.  Howard received  an option for  15,150 shares.  For 1994,  Mr.
Howard  also received 5,197  shares of restricted  stock (47% of  his base pay).
These amounts were determined as  described above for other executive  officers.
The  terms  of  the options  and  restricted stock  are  the same  as  for other
executive officers.

    In an effort to retain top  quality employees with expertise in the  nuclear
field, Mr. Antony received an additional 2,200 shares of restricted stock during
1994  pursuant to a restricted stock agreement outside the LTIP. Under the terms
of the Agreement, these  shares vest with  respect to 50% of  the shares if  Mr.
Antony  has been  continually employed  with NSP on  October 26,  1996, and with
respect to  the remainder  of the  shares  if Mr.  Antony has  been  continually
employed  with NSP on October 26, 1998. All restricted shares held by Mr. Antony
are reflected on the Summary Compensation Table.

    OTHER BENEFITS.   Other benefits  provided to executives  generally are  not
tied  to  NSP's  financial  performance. Rather,  these  benefits  are primarily
designed to attract and retain executives. Among the benefits provided by NSP to
its executives are contributions to the  Employee Stock Ownership Plan (at  1.3%
of  the individual's covered compensation -- the  same rate applied to all other
ESOP participants), NSP paid life insurance in  an amount equal to 2 times  base
pay  and benefits provided under the NSP  Deferred Compensation Plan and the NSP
Excess Benefit Plan that make up for pension benefits that can not be paid under
NSP's qualified defined  benefit pension plan  due to Code  limitations and  the
exclusion of certain elements of pay from pension-covered earnings. The level of
retirement benefits provided by these plans in the aggregate is reflected in the
Pension Plan Table.

    CONCLUSION.     The  Corporate  Management  Committee  believes  that  NSP's
executive compensation package effectively serves  the interests of NSP and  its
shareholders.  The  balance of  base pay,  and  annual and  long-term incentives
provides increased motivation to executives to contribute to and participate  in
NSP's  long-term  success. The  Corporate Management  Committee is  dedicated to
ensuring that NSP's total  compensation package continues to  meet the needs  of
NSP and shall monitor and revise compensation policies as necessary.

(1)  NSP  has selected  the EEI  100 index  for this  comparison because  of its
     timely production of index data and its similarity to the index used in the
     1994 proxy  statement. Except  for  MDU Resources  Group, Inc.  (which  was
     represented  in last  year's index, but  is not  in the EEI  100 index) and
     ESELCO (which is represented in  the EEI 100 index,  but was not in  1994's
     index),  the  utility  companies  represented  in  the  EEI  100  index are
     identical to those represented in 1994. The Kidder Peabody Electric Utility

</TABLE>

    After an employee has reached 30  years of service, no additional years  are
used  in determining pension benefits. The annual compensation used to calculate
the average compensation shown in this table is based on the participant's  base
salary  for the year (as shown on  the Summary Compensation Table at column (c))
and bonus  compensation  paid  in  that  same year  (as  shown  on  the  Summary
Compensation  Table  at column  (d);  see figure  for  prior year).  The benefit
amounts shown are amounts computed in  the form of a straight-life annuity.  The
amounts  are not subject to  offset for social security  or otherwise, except as
provided in the employment agreement with Mr. Howard, as described below. At the
end of 1994, each  of the executive officers  named in the Summary  Compensation
Table  had the following  credited service: Mr. Howard,  7.92 years, Mr. Antony,
25.5 years, Mr.  Johnson, 16.08 years,  Mr. McIntyre, 21.83  years, Mr.  Taylor,
21.58 years and Mr. Theisen, 40 years.

    An  employment  agreement  with  Mr.  Howard  provides  that,  if employment
terminates prior to  age 60,  he will receive  payments from  NSP equivalent  to
benefits  he would have earned under the  Pension Plan without regard to service
and  compensation  limitations  in  a  minimum  annual  amount  of  $22,535.  If
employment  continues past age 60, he and  his spouse, if she survives him, will
receive combined benefits from the Pension Plan and supplemental NSP payments as
though he had completed  30 years of service,  less the pension benefits  earned
from a former employer.

                                SEVERANCE PLANS

    NSP's  Severance  Plan covers  the full-time  regular-benefit, nonbargaining
employees  of   NSP,  including   the   named  executives,   and   participating
subsidiaries.   The  Severance  Plan  provides  severance  benefits  to  covered
employees whose  termination  of  employment is  involuntary  and  unrelated  to
unsatisfactory  performance. Subject to a maximum of 24 months of pay, a covered
employee is eligible to receive monthly payments of two months of base pay  plus
the  greater of two weeks  of base pay for  each year of service  or one week of
base pay  for each  $2,000 of  base annual  salary. Covered  employees are  also

                                      135
<PAGE>
                   [ALTERNATE PAGE FOR NSP SHAREHOLDERS ONLY]
eligible  to receive  incentive pay,  group insurance  benefits and  service and
compensation credit under the Pension Plan  for the period they receive  monthly
severance benefits. Outplacement services are also provided under the Plan.

    NSP  also recently  adopted another  severance plan  in connection  with its
entering into the Merger Agreement with WEC. For a description of the  employees
covered  by such plan and the terms  thereof, see "The Mergers -- Employee Plans
and Severance Arrangements."

             RATIFICATION OF APPOINTMENT OF INDEPENDENT ACCOUNTANTS

    During 1994, NSP solicited proposals from six independent public  accounting
firms  to provide auditing  services to NSP. After  reviewing and evaluating the
qualifications of the firms,  the services proposed,  and the associated  costs,
the  Audit  Committee  of the  NSP  Board  recommended a  change  of independent
accountants. On December 14, 1994, the NSP Board approved the Audit  Committee's
recommendation  that  Price  Waterhouse  LLP  be  appointed  as  the independent
accountants  to  certify  NSP's  financial  statements  for  1995,  subject   to
ratification  by the shareholders. Deloitte &  Touche LLP has been informed that
their firm would no longer be engaged as independent accountants for NSP and its
subsidiaries after  the completion  of  audit work  for  the fiscal  year  ended
December  31, 1994. Deloitte & Touche LLP has been NSP's independent accountants
since 1947.

    During the two most  recent fiscal years ended  December 31, 1993 and  1994,
and  during subsequent interim periods through the date of this proxy statement,
there were  no  disagreements  with Deloitte  &  Touche  LLP on  any  matter  of
accounting principles or practices, financial statement disclosures, or auditing
scope  or procedures,  which if not  resolved to their  satisfaction, would have
caused Deloitte & Touche LLP to make reference thereto in connection with  their
reports.  Deloitte & Touche LLP's reports  on NSP's financial statements for the
two most  recent fiscal  years ended  December 31,  1993 and  1994 contained  no
adverse  opinion or disclaimer of opinion and  were not qualified or modified as
to uncertainty or audit  scope. Such reports included  a fourth paragraph  which
referred  to a change  in NSP's method of  accounting for post-retirement health
care costs in 1993.

    If the shareholders do not ratify the selection of Price Waterhouse LLP, the
NSP Board will  consider the  appointment of other  independent accountants  for
1995, as recommended by the Audit Committee.

    Representatives from Deloitte & Touche LLP are expected to be present at the
NSP  Meeting  to  answer  questions regarding  their  audit  of  NSP's financial
statements for  1994  and  to  make  a  statement  if  they  desire  to  do  so.
Representatives  from Price Waterhouse LLP are expected to be present at the NSP
Meeting to  answer  questions  on their  appointment  for  1995 and  to  make  a
statement if they desire to do so.

    THE  NSP BOARD UNANIMOUSLY RECOMMENDS THAT  YOU VOTE FOR RATIFICATION OF THE
APPOINTMENT OF ACCOUNTANTS.

                             SHAREHOLDER PROPOSALS

    Yvonne Ford, 6308 Barrie Road, Edina, MN 55435, beneficial owner of  238.942
shares  of NSP  Common Stock, and  John W. Harmon,  1221 39th Avenue  NE Ste. 2,
Columbia Heights, MN 55421, beneficial owner of 0.248 shares of NSP Common Stock
have given notice that they intend to present for action at the NSP Meeting  the
following resolution:

                     Shareholder Resolution on Public Image

    Whereas: Radiation, a byproduct of nuclear power, is a known carcinogen;

   Whereas:  A recent  study by  Doctors Ernest  R. Sternglass  and J.  M. Gould
   suggest that since  NSP's nuclear  plants were  built women  living near  the
   reactors  have experienced large increases in deaths from breast cancer while
   deaths among those living elsewhere have decreased.

                                      136
<PAGE>
                   [ALTERNATE PAGE FOR NSP SHAREHOLDERS ONLY]

   Whereas: In our opinion, radioactive and toxic waste from the production  and
   use of nuclear fuel is more often than not stored near black, Indian and poor
   communities.  As a result these communities bear an unfair share of risks and
   threats. In our opinion,  the burden on  these communities is  "environmental
   racism" which is a vital moral issue;

   Whereas: These health effects and this environmental racism reflect poorly on
   NSP's public image and can cause undesirable effects on shareholder equity;

   Therefore  be it  resolved that  the shareholders  recommend to  the Board of
   Directors that NSP stop producing radioactive waste.

    THE NSP BOARD  RECOMMENDS A  VOTE AGAINST  THIS PROPOSAL  FOR THE  FOLLOWING
REASONS:

    The  foregoing statement and resolution were included herein by NSP in order
to comply with the  rules of the SEC.  The NSP Board believes  that many of  the
assertions  and the  implications put forward  by this  shareholder proposal are
incorrect. There  is  absolutely  no scientifically  verifiable  evidence  which
suggests  any  correlation  whatsoever  between breast  cancer  and  living near
nuclear power plants in  the United States. The  Minnesota Department of  Health
(the  "MDH") recently submitted a report to the Minnesota Legislature concerning
this issue. In its conclusion, the MDH stated:

      The major purpose of this analysis  was to respond to the allegation  that
      breast  cancer mortality rates in counties surrounding Minnesota's nuclear
      power plants  had shown  large  and dramatic  increases during  the  1980s
      compared    to    the    early   1980s    and    the   1950s    .    .   .
       THIS ANALYSIS PROVIDES A CLEAR AND UNAMBIGUOUS CONCLUSION: BREAST  CANCER
      MORTALITY  TRENDS  OVER  THE PERIOD  1950-1992  IN THE  TEN  COUNTIES NEAR
      NUCLEAR POWER PLANTS SHOW NO DISCERNIBLE DIFFERENCE FROM STATEWIDE TRENDS.
      THERE WERE ALSO NO DIFFERENCES FOUND IN THE RATE OF NEWLY-DIAGNOSED BREAST
      CANCER  DURING   THE  PERIOD   1988-1992  FOR   WHICH  [MINNESOTA   CANCER
      SURVEILLANCE SYSTEM] DATA ARE AVAILABLE.

This  MDH  report was  consistent with  a  prior report  of the  National Cancer
Institute which  "found no  suggestion  that nuclear  facilities may  be  linked
causally  with excess deaths from leukemia  or from other cancers in populations
living nearby."

    In addition,  implementation  of  the  proposal would  cause  NSP  to  cease
entirely  the production of nuclear power and to close NSP's nuclear facilities.
NSP estimates that the present value of the costs of complying with the proposal
and shutting down NSP's nuclear facilities would exceed $2.5 billion. While  NSP
would seek to recover these costs from customers, there is no guarantee that all
such  costs  would  be  recovered.  Even  if  these  costs  were  recovered, the
unnecessary imposition of an estimated $2.5 billion in costs on ratepayers would
likely cause NSP to lose its position as a low-cost supplier of electricity  and
could seriously impair NSP's ability to compete against other electric suppliers
in  the years ahead, substantially lessening shareholder value. ACCORDINGLY, THE
NSP BOARD  AND  MANAGEMENT UNANIMOUSLY  RECOMMEND  THAT YOU  VOTE  AGAINST  THIS
PROPOSAL.

notice  that they intend to present for  action at the NSP Meeting the following
resolution:

<PAGE>
                   [ALTERNATE PAGE FOR NSP SHAREHOLDERS ONLY]

                  SHAREHOLDER RESOLUTION ON REGULATORY REFORM

   WHEREAS, our  company must  eventually eliminate  the costs  and  liabilities
   attached  to  our use  of  nuclear and  fossil  fuels for  providing electric
   utility services,  and  shift  to  the  efficient  use  of  renewable  energy
   resources. At issue is the timing and speed of this transition.

   Fission wastes from the nuclear fuel chain threaten public health and safety;
   the  potential  for  human  error and  technology  failure  at  NSP's nuclear
   facilities threatens public health and  safety as well as shareholder  equity
   and  earnings; and combustion  wastes from NSP's coal  fired power plants are
   major contributors to wholesale ecological and public health degradation  due
   to mercury contamination, acidification, and global warming.

   Furthermore,   Minnesotans  miss  vital  economic  opportunities  because  we
   annually export  many hundred  million  dollars to  import NSP's  fossil  and
   nuclear fuels that degrade our environment.

   These  environmental and economic problems are  the result of two fundamental
   problems with electric utility regulation. The demand-side problem is related
   to how consumers purchase electric utility services. The supply-side  problem
   is  related to how electricity is produced. The demand-side problem increases
   NSP's  earnings  as  energy  sales  increase,  while  the  efficient  use  of
   electricity  tends to erode  earnings. In other  words, NSP shareholders make
   more money as NSP produces more radioactive waste and fossil fuel  pollution.
   Regulations should be changed so that shareholders earnings depend instead on
   the  efficient  use of  electricity. The  supply-side problem  protects NSP's
   nuclear and  fossil fuel  facilities from  fair market  competition based  on
   actual  energy production  costs. This  prevents energy  consumers from using
   renewable energy resources  and technologies that  are better from  society's
   perspective.

   THEREFORE BE IT RESOLVED that shareholders recommend that the board:

          1.  Propose and support electric utility regulatory reform so that NSP
          earnings  increase only as a function  of NSP's ability to demonstrate
          that  its  demand-side   investments  cause  its   consumers  to   use
          electricity more efficiently;

          2.   Propose and  support regulatory reform  so that independent power
          producers can compete in NSP's  energy market, with competition  based
          on  energy pricing that includes fair value for presently externalized
          capital, environmental and societal costs and benefits appropriate for
          each energy resource.

    THE NSP BOARD  RECOMMENDS A  VOTE AGAINST  THIS PROPOSAL  FOR THE  FOLLOWING
REASONS:

    The  NSP Board believes  adoption of this proposal  would depress the future
earnings of NSP and its shareholders, reduce  the total equity value of NSP  and
unnecessarily restrict NSP's competitive options.

    The  proposal would limit increases in  NSP's and its shareholders' earnings
to one factor (I.E.,  demand-side investment), which the  NSP Board believes  is
totally  inappropriate. The earnings of NSP and its shareholders are affected by
numerous factors,  many  of  which  are not  tied  to  demand-side  investments.
Limiting  increases in earnings to one factor as requested by the proposal would
be detrimental  to NSP's  earning  power and,  in  turn, to  shareholder  value.
Moreover,  Minnesota law already requires NSP to support conservation efforts by
applying a  percentage  of  its  annual  revenues  to  Minnesota  regulators  to
determine the maximum level of conservation NSP can economically and efficiently
provide  to its customers.  NSP currently offers  over 40 demand-side management
programs to its  customers. In 1994  alone, NSP spent  more than $50,000,000  on
demand-side  management matters, which helped  NSP's customers conserve the need
for 350,000 megawatt hours of energy and 130 megawatts of peak demand.

    The  proposal  also  addresses  competition.  NSP  is  already   undertaking
regulatory  initiatives  to promote  competition in  the energy  markets. Recent
actions by NSP include: (i) proposing to the Minnesota Commission a  competitive
bidding  process for all  future generation needs;  (ii) filing with  the FERC a
revised transmission tariff that is designed to supply service to the  potential
transmission  users, including independent power producers,  in a manner that is
comparable to NSP's own use of its transmission system; and (iii) supporting  in
a proceeding before the Wisconsin Commission changes in the regulatory structure
that  would allow,  among other  elements, competition  at the  retail level. In
addition, under Minnesota law, NSP is mandated to consider the environmental and
socioeconomic impact  of  various supply  options  when selecting  a  generation
resource.  For these reasons, the  NSP Board also believes  that the proposal is
unnecessary and would impair NSP's flexibility to respond to competitive changes
in the electric industry.

    ACCORDINGLY, THE NSP  BOARD AND  MANAGEMENT UNANIMOUSLY  RECOMMEND THAT  YOU
VOTE AGAINST THIS PROPOSAL.

                                   ARTICLE II
                              TREATMENT OF SHARES

    subject  to Section 180.0622(2)(b)  of the WBCL,  as judicially interpreted,
    non-assessable share of NSP Common  Stock. Upon such cancellation, all  such
    shares  of Old NSP Common  Stock shall cease to exist,  and each holder of a
    certificate formerly representing any  such shares of  Old NSP Common  Stock
    shall  cease to have  any rights with  respect thereto, except  the right to
    receive the  shares  of NSP  Common  Stock  to be  issued  in  consideration
    therefor  and, following the NSP Merger, the  right to receive the shares of
    Company Common Stock  (as defined  in SECTION  2.1(B)(II)) to  be issued  in
    consideration  therefor upon the surrender of such certificate in accordance
    with SECTION 2.3.

    share  of Cumulative  Preferred Stock, par  value $100.00 per  share, of NSP

    dividend    rates)   and   designations   to    the   cancelled   share   of

                                      A-9
<PAGE>
    Old NSP Preferred Stock. Upon such cancellation, all such shares of Old  NSP
    Preferred  Stock  shall cease  to exist,  and each  holder of  a certificate
    formerly representing any such shares of Old NSP Preferred Stock shall cease
    to have any  rights with respect  thereto, except the  right to receive  the
    shares  of NSP Preferred Stock to be issued in consideration therefor, which
    shares of  NSP Preferred  Stock  shall be  represented by  the  certificates
    formerly representing shares of Old NSP Preferred Stock.

    (b)  At the NSP Effective Time, by virtue  of the NSP Merger and without any
action on the part of any holder of any capital stock of New NSP or WEC Sub:

        (i)  CANCELLATION OF CERTAIN NSP STOCK.  Each share of NSP Common  Stock

        (ii)  TREATMENT OF NSP COMMON STOCK.  Each issued and outstanding  share
    of  NSP  Common  Stock  (other than  shares  cancelled  pursuant  to SECTION

    of Common Stock, par value  $.01 per share, of  WEC (the "WEC COMMON  STOCK"
    and,  with  respect to  any period  after the  Effective Time,  the "COMPANY
    COMMON STOCK"). Upon such cancellation, all such Shares of NSP Common  Stock
    shall cease to exist, and each holder of a certificate formerly representing
    any  such shares shall cease to have any rights with respect thereto, except
    the right to  receive the shares  of Company  Common Stock to  be issued  in
    consideration  therefor upon the surrender of such certificate in accordance
    with SECTION 2.3.

        (iii)  NO CHANGE  IN NSP PREFERRED STOCK.   Each issued and  outstanding

    converted  into one fully paid and, subject to Section 180.0622(2)(b) of the
    WBCL, as judicially interpreted, non-assessable share of NSP Common Stock.

    Section 2.2  DISSENTING SHARES.  Shares of Old NSP Common Stock and Old  NSP
Preferred  Stock  held  by  any  holder  entitled  to  relief  as  a  dissenting
shareholder under Section  302A.471 of  the MBCA (the  "NSP DISSENTING  SHARES")
shall  not become the right to receive  NSP Common Stock or NSP Preferred Stock,
as the case may  be, in the Reincorporation  Merger or, in the  case of Old  NSP
Common  Stock, into the right to receive Company Common Stock in the NSP Merger,
but shall be cancelled and converted into such consideration as may be due  with
respect to such shares pursuant to the applicable provisions of the MBCA, unless
and  until the  right of  such holder to  receive fair  cash value  for such NSP
Dissenting Shares terminates in accordance with Section 302A.473 of the MBCA. If
such right is terminated otherwise than by  the purchase of such shares by  NSP,
then such shares shall cease to be NSP Dissenting Shares and shall represent the
right  to receive Company  Common Stock, as  provided in SECTION  2.1(B), or NSP
Preferred Stock, as provided in SECTION 2.1(A).

    Section 2.3  ISSUANCE OF NEW CERTIFICATES.

    (a)   DEPOSIT  WITH  EXCHANGE AGENT.    As  soon as  practicable  after  the
Effective  Time,  the Company  shall  deposit with  such  bank or  trust company
mutually  agreeable  to  WEC  and  NSP  (the  "EXCHANGE  AGENT"),   certificates
representing  shares of  Company Common  Stock required  to effect  the issuance
referred to in SECTION 2.1, together with cash payable in respect of  fractional
shares pursuant to SECTION 2.3(D).

    (b)   ISSUANCE PROCEDURES.  As soon as practicable after the Effective Time,
the Exchange Agent shall mail (x) to  each holder of record of a certificate  or
certificates (the "CERTIFICATES") which immediately prior to the Reincorporation
Effective Time represented outstanding shares of Old NSP

                                      A-10
<PAGE>
Common  Stock (the  "CANCELLED COMMON  SHARES") that  were cancelled  and became
instead the  right to  receive  shares of  Company  Common Stock  (the  "COMPANY
SHARES")  pursuant  to SECTION  2.1, (i)  a letter  of transmittal  (which shall
specify that delivery  shall be  effected, and  risk of  loss and  title to  the
Certificates  shall pass, only  upon actual delivery of  the Certificates to the
Exchange Agent) and (ii) instructions for use in effecting the surrender of  the
Certificates  in  exchange for  certificates  representing Company  Shares. Upon
surrender of a Certificate  to the Exchange Agent  for cancellation (or to  such
other agent or agents as may be appointed by agreement of NSP and WEC), together
with  a duly  executed letter  of transmittal  and such  other documents  as the
Exchange Agent shall require, the holder  of such Certificate shall be  entitled
to  receive a certificate representing that number of whole Company Shares which
such holder has the right to receive pursuant to the provisions of this  ARTICLE
II.  In the event of a transfer of ownership of Cancelled Common Shares which is
not registered in the  transfer records of NSP,  a certificate representing  the
proper number of Company Shares may be issued to a transferee if the Certificate
representing  such Cancelled Common  Shares is presented  to the Exchange Agent,
accompanied by all documents required to  evidence and effect such transfer  and
by  evidence  satisfactory  to  the Exchange  Agent  that  any  applicable stock
transfer taxes have been paid. Until surrendered as contemplated by this SECTION
2.3, each Certificate shall be  deemed at any time  after the Effective Time  to
represent  only  the  right  to  receive  upon  such  surrender  the certificate
representing Company Shares and cash in lieu of any fractional shares of Company
Common Stock as contemplated by this SECTION 2.3.

    (c)  DISTRIBUTIONS WITH  RESPECT TO UNSURRENDERED SHARES.   No dividends  or
other  distributions declared or  made after the Effective  Time with respect to
Company Shares with a record date after the Effective Time shall be paid to  the
holder  of  any unsurrendered  Certificate with  respect  to the  Company Shares
represented thereby and no  cash payment in lieu  of fractional shares shall  be
paid to any such holder pursuant to SECTION 2.3(d) until the holder of record of
such  Certificate shall  surrender such  Certificate. Subject  to the  effect of
unclaimed property, escheat  and other applicable  laws, following surrender  of
any  such  Certificate,  there  shall  be  paid  to  the  record  holder  of the
certificates representing whole Company Shares issued in consideration therefor,
without interest, (i)  at the time  of such  surrender, the amount  of any  cash
payable  in lieu  of a fractional  share of  Company Common Stock  to which such
holder is entitled  pursuant to SECTION  2.3(d) and the  amount of dividends  or
other distributions with a record date after the Effective Time theretofore paid
with  respect to such whole  Company Shares and (ii)  at the appropriate payment
date, the amount of  dividends or other distributions  with a record date  after
the  Effective Time  but prior  to surrender  and a  payment date  subsequent to
surrender payable with respect to such whole Company Shares.

    (d)  NO FRACTIONAL SECURITIES.  Notwithstanding any other provision of  this
Agreement,  no certificates or  scrip representing fractional  shares of Company
Common Stock shall be issued upon the surrender for exchange of Certificates and
such fractional shares shall  not entitle the  owner thereof to  vote or to  any
other  rights of a holder of Company Common  Stock. A holder of NSP Common Stock
who would otherwise have been entitled  to a fractional share of Company  Common
Stock  shall be entitled  to receive a  cash payment in  lieu of such fractional
share in an  amount equal  to the  product of  such fraction  multiplied by  the
average  of the last reported sales price,  regular way, per share of WEC Common
Stock on  the  New York  Stock  Exchange ("NYSE")  Composite  Tape for  the  ten
business  days prior  to and including  the last  business day on  which Old NSP
Common Stock was traded on the NYSE, without any interest thereon.

    (e)  BOOK ENTRY.  Notwithstanding any other provision of this Agreement, the
letter of transmittal referred to  in SECTION 2.3(b) may,  at the option of  the
Company,  provide for  the ability of  a holder  of one or  more Certificates to
elect that  the Company  Shares to  be received  in exchange  for the  Cancelled
Common Shares formerly represented by such surrendered Certificates be issued in
uncertificated  form or  to elect  that such  Company Shares  be credited  to an
account established for  the holder  under the dividend  reinvestment and  stock
purchase plan of the Company.

                                      A-11
<PAGE>
    (f)   CLOSING OF TRANSFER BOOKS.  From  and after the NSP Effective Time the
stock transfer books of NSP shall be closed and no transfer of any capital stock
of NSP shall thereafter be made. If, after the Effective Time, Certificates  are
presented to the Company, they shall be cancelled and exchanged for certificates
representing  the  appropriate number  of Company  Shares,  as provided  in this
SECTION 2.3.

    (g)  TERMINATION OF EXCHANGE  AGENT.  Any certificates representing  Company
Shares  deposited with  the Exchange  Agent pursuant  to SECTION  2.3(a) and not
exchanged within one year after the Effective Time pursuant to this SECTION  2.3
shall  be returned by the Exchange Agent  to the Company, which shall thereafter
act as Exchange Agent. All funds held  by the Exchange Agent for payment to  the
holders  of unsurrendered Certificates and unclaimed at the end of one year from
the Effective Time shall be returned to the Company, after which time any holder
of unsurrendered  Certificates shall  look as  a general  creditor only  to  the
Company  for payment of such  funds to which such holder  may be due, subject to
applicable law. The Company shall not be liable to any person for such shares or
funds delivered  to  a public  official  pursuant to  any  applicable  abandoned
property, escheat or similar law.

                                  ARTICLE III
                                  THE CLOSING

    announcement of  any transaction  contemplated by  this Agreement  will  not
    (either  alone or upon the  occurrence of any additional  or further acts or
    events) result in any  (A) payment (whether of  severance pay or  otherwise)
    becoming  due  from NSP  or  any of  the  NSP Subsidiaries  to  any officer,
    employee, former employee or  director thereof or to  the trustee under  any

    in  respect  of services  provided to  any such  entity, including,  but not
    limited to, any employee benefit plans within the meaning of Section 3(3) of
    ERISA and any severance  or change in  control agreement (collectively,  the

    arising  under  the  Code, ERISA  or  any other  applicable  law (including,
    without limitation, any liability  to any such plan  or the PBGC), or  under

    announcement of  any transaction  contemplated by  this Agreement  will  not
    (either  alone or upon the  occurrence of any additional  or further acts or
    events) result in any  (A) payment (whether of  severance pay or  otherwise)
    becoming  due  from WEC  or  any of  the  WEC Subsidiaries  to  any officer,
    employee, former employee or  director thereof or to  the trustee under  any
    "rabbi  trust" or similar arrangement, or  (B) benefit under any WEC Benefit
    Plan being established or becoming  accelerated, vested or payable and  (ii)
    neither  WEC  nor  any  of  the  WEC Subsidiaries  is  a  party  to  (A) any

    to  the best knowledge of WEC, threatened, in respect of which any director,
    officer, employee or agent of WEC or  any of the WEC Subsidiaries is or  may
    be  entitled  to  claim  indemnification from  WEC  or  such  WEC Subsidiary
    pursuant to  their respective  articles of  incorporation or  by-laws or  as

    whole.

        (b)   DIVIDENDS.  No party shall, nor  shall any party permit any of its

    accordance with the respective terms thereof, regular quarterly dividends on

    year,  in excess  of 106%  of the  dividends for  the prior  fiscal year and

    Common Stock or Old NSP Common Stock, as the case may be, shall be the  same
    date  and  shall  be  prior  to  the  Effective  Time.  Notwithstanding  the

    exemption  pursuant  to  its  order  under  Section  3(a)(1)  of  the   1935

                                      A-31

        (m)   POOLING.   No party shall, nor  shall any party  permit any of its

    pursuant to this Agreement as a pooling of interests in accordance with GAAP
    and applicable  SEC  regulations,  and  each  party  hereto  shall  use  all
    reasonable  efforts to achieve such result (including taking such actions as

    obtained with an unaffiliated third party on an arm's-length basis.

        (p)  COOPERATION, NOTIFICATION.  Each  party shall, and shall cause  its
    Direct  Subsidiaries to, (i) confer on a regular and frequent basis with one

    the other party with copies of all filings made by such party or any of  its
    Direct  Subsidiaries with any state or federal court, administrative agency,

        (q)  RATE  MATTERS.   Each of  NSP and WEC  shall, and  shall cause  its
    Direct  Subsidiaries to, discuss  with the other  any changes in  its or its
    Direct Subsidiaries' rates or charges (other than pass-through fuel and  gas
    rates  or charges), standards of service  or accounting from those in effect
    on the date hereof and consult with the other prior to making any filing (or
    any amendment thereto), or effecting any agreement, commitment,  arrangement
    or consent with governmental

                                      A-32
<PAGE>
    regulators,  whether  written  or  oral, formal  or  informal,  with respect
    thereto, and no party will make any filing to change its rates on file  with
    the  FERC  that  would  have  a  material  adverse  effect  on  the benefits
    associated with the business combination provided for herein.

        (r)   THIRD-PARTY CONSENTS.    NSP shall,  and  shall cause  its  Direct
    Subsidiaries  to, use all commercially reasonable  efforts to obtain all NSP
    Required  Consents.  NSP  shall  promptly  notify  WEC  of  any  failure  or

    reasonably likely to result  in a material breach  of any provision of  this
    Agreement, the NSP Stock Option Agreement or the WEC Stock Option Agreement,
    as  the case  may be, or  in any  of its representations  and warranties set
    forth in this Agreement,  the NSP Stock Option  Agreement, or the WEC  Stock
    Option  Agreement, as the case may be, being untrue on and as of the Closing
    Date.

        (t)  TAX-EXEMPT STATUS.  No party shall, nor shall any party permit  any
    Direct  Subsidiary  to, take  any action  that  would likely  jeopardize the
    qualification of NSP's or WEPCO's outstanding revenue bonds which qualify on
    the date hereof under Section 142(a) of the Code as "exempt facility  bonds"
    or as tax-exempt industrial development bonds under Section 103(b)(4) of the
    Internal  Revenue Code of 1954,  as amended, prior to  the Tax Reform Act of
    1986.

    compromise  any  material  claim,  action,  suit,  litigation,   proceeding,
    arbitration,  investigation,  audit  or controversy  relating  to  taxes, or
    change any of  its methods  of reporting  income or  deductions for  federal
    income  tax purposes from  those employed in the  preparation of its federal
    income tax return for the taxable  year ending December 31, 1993, except  as
    may be required by applicable law.

        (w)  DISCHARGE OF LIABILITIES.  No party shall pay, discharge or satisfy
    any material claims, liabilities or obligations (absolute, accrued, asserted
    or  unasserted, contingent or otherwise),  other than the payment, discharge
    or satisfaction, in  the ordinary  course of business  consistent with  past
    practice (which includes the payment of final and unappealable judgments) or
    in accordance with their terms, of liabilities reflected or reserved against
    in,  or contemplated by,  the most recent  consolidated financial statements
    (or the notes thereto) of such party included in such party's reports  filed
    with the SEC, or incurred in the ordinary course of business consistent with
    past practice.

        (x)    CONTRACTS.   No party  shall,  except in  the ordinary  course of

STATEMENT").  The parties hereto shall each  use reasonable efforts to cause the
Registration Statement  to be  declared effective  under the  Securities Act  as
promptly  as practicable  after such filing.  Each party hereto  shall also take
such action as may be reasonably required to cause the shares of Company  Common

service  of process  in any  jurisdiction where  it will  not be,  following the
Mergers, so subject. Each  of the parties hereto  shall furnish all  information
concerning  itself which  is required  or customary  for inclusion  in the Joint
Proxy/Registration Statement. The parties shall use reasonable efforts to  cause
the  shares of Company Common  Stock issuable in the  Mergers to be approved for
listing on the NYSE upon official  notice of issuance. The information  provided
by  any party hereto for use in  the Joint Proxy/Registration Statement shall be
true and correct in all material respects without omission of any material  fact
which  is  required  to  make  such  information  not  false  or  misleading. No
representation, covenant or agreement is made  by any party hereto with  respect
to  information supplied  by any  other party for  inclusion in  the Joint Proxy
Statement/Registration Statement.

    (b)  LETTER OF NSP'S ACCOUNTANTS.  NSP shall use best efforts to cause to be

Form S-4.

    (d)  FAIRNESS OPINIONS.  It shall be a condition to the mailing of the Joint
Proxy/Registration Statement to  the shareholders of  NSP and WEC  that (i)  NSP

    Section 7.5  DIRECTORS' AND OFFICERS' INDEMNIFICATION.

    (a)  INDEMNIFICATION.  To  the extent, if any,  not provided by an  existing
right  of  indemnification or  other  agreement or  policy,  from and  after the
Effective Time, the Company shall, to the fullest extent permitted by applicable
law, indemnify, defend and hold harmless each person who is now, or has been  at
any  time prior to the date hereof, or  who becomes prior to the Effective Time,
an officer, director or employee of any of the parties hereto or any  subsidiary
(each  an  "INDEMNIFIED  PARTY"  and  collectively,  the  "INDEMNIFIED PARTIES")
against (i)  all  losses, expenses  (including  reasonable attorney's  fees  and
expenses), claims, damages or liabilities or, subject to the proviso of the next
succeeding  sentence,  amounts paid  in settlement,  arising  out of  actions or
omissions occurring at or prior to  the Effective Time (and whether asserted  or
claimed prior to, at or after the Effective Time) that are, in whole or in part,
based  on or  arising out of  the fact  that such person  is or  was a director,
officer or employee of such party (the "INDEMNIFIED LIABILITIES"), and (ii)  all
Indemnified  Liabilities to  the extent  they are  based on  or arise  out of or
pertain to the transactions contemplated by this Agreement. In the event of  any
such  loss, expense, claim,  damage or liability (whether  or not arising before
the Effective Time), (i) the Company shall pay the reasonable fees and  expenses
of  counsel  selected  by  the  Indemnified  Parties,  which  counsel  shall  be
reasonably satisfactory to the Company, promptly after

                                      A-36
<PAGE>
statements therefor are received and otherwise advance to such Indemnified Party
upon request reimbursement of documented expenses reasonably incurred, in either
case  to  the  extent  not  prohibited  by the  WBCL  and  upon  receipt  of any
affirmation and undertaking required by Section  180.0853 of the WBCL, (ii)  the
Company  will  cooperate  in  the  defense of  any  such  matter  and  (iii) any
determination required to be made with respect to whether an Indemnified Party's
conduct complies  with the  standards  set forth  under  Wisconsin law  and  the
Restated  Articles of  Incorporation (including  the WEC  Article Amendments) or
By-laws of the Company (as the same  shall be amended pursuant to SECTION  7.20)
shall  be made by independent counsel mutually acceptable to the Company and the
Indemnified Party; PROVIDED, HOWEVER, that the  Company shall not be liable  for
any  settlement effected without its written consent (which consent shall not be
unreasonably withheld). The Indemnified Parties as  a group may retain only  one
law  firm with respect to each related matter  except to the extent there is, in
the opinion of counsel  to an Indemnified Party,  under applicable standards  of
professional  conduct, a conflict on any  significant issue between positions of
such Indemnified Party and any other Indemnified Party or Indemnified Parties.

    (b)  INSURANCE.   For a period  of six years after  the Effective Time,  the
Company  shall  cause to  be  maintained in  effect  policies of  directors' and
officers' liability insurance maintained by NSP and WEC for the benefit of those
persons who are currently  covered by such policies  on terms no less  favorable
than  the terms of such current  insurance coverage; PROVIDED, HOWEVER, that the
Company shall not be required to expend in any year an amount in excess of  200%
of  the  annual  aggregate premiums  currently  paid  by NSP  and  WEC  for such
insurance; and PROVIDED, FURTHER, that if the annual premiums of such  insurance
coverage  exceed such amount, the Company shall  be obligated to obtain a policy
with the best  coverage available, in  the reasonable judgment  of the Board  of
Directors of the Company, for a cost not exceeding such amount.

    (c)   SUCCESSORS.   In  the event the  Company or  any of  its successors or
assigns (i) consolidates with or merges into  any other person and shall not  be
the  continuing  or surviving  corporation or  entity  of such  consolidation or
merger or (ii) transfers all or  substantially all of its properties and  assets
to  any person, then and in either such case, proper provisions shall be made so
that the successors and assigns of the Company shall assume the obligations  set
forth in this SECTION 7.5.

    (d)   SURVIVAL OF INDEMNIFICATION.  To  the fullest extent permitted by law,
from and after the Effective Time, all rights to indemnification as of the  date
hereof in favor of the employees, agents, directors and officers of NSP, WEC and
their  respective subsidiaries with respect to their activities as such prior to
the Effective Time, as  provided in their  respective articles of  incorporation
and  by-laws in effect  on the date hereof,  or otherwise in  effect on the date
hereof, shall survive the  Mergers and shall continue  in full force and  effect
for a period of not less than six years from the Effective Time.

    (e)  BENEFIT.  The provisions of this SECTION 7.5 are intended to be for the
benefit  of, and  shall be  enforceable by, each  Indemnified Party,  his or her
heirs and his or her representatives.

delivered  to NSP a  schedule (the "WEC DISCLOSURE  SCHEDULE"), accompanied by a
certificate signed  by  the chief  financial  officer  of WEC  stating  the  WEC
Disclosure  Schedule is being delivered pursuant to this SECTION 7.6(i) and (ii)
NSP has delivered to WEC a schedule (the "NSP DISCLOSURE SCHEDULE"), accompanied
by a certificate signed by  the chief financial officer  of NSP stating the  NSP
Disclosure Schedule is being delivered pursuant to this SECTION 7.6(II). The NSP
Disclosure Schedule and the WEC Disclosure Schedule are collectively referred to
herein  as the  "DISCLOSURE SCHEDULES".  The Disclosure  Schedules constitute an
integral part  of  this Agreement  and  modify the  respective  representations,
warranties,  covenants or agreements  of the parties  hereto contained herein to
the extent  that  such  representations,  warranties,  covenants  or  agreements
expressly  refer to the Disclosure Schedules. Anything to the contrary contained
herein or in the Disclosure  Schedules notwithstanding, any and all  statements,
representations, warranties or disclosures set forth in the Disclosure Schedules
shall be deemed to have been made on and as of the date hereof.

    Section  7.7   PUBLIC  ANNOUNCEMENTS.   Subject  to each  party's disclosure
obligations imposed by law, NSP  and WEC will cooperate  with each other in  the
development  and distribution of all news  releases and other public information
disclosures  with  respect  to  this  Agreement  or  any  of  the   transactions
contemplated  hereby and  shall not issue  any public  announcement or statement
with respect hereto  or thereto without  the consent of  the other party  (which
consent shall not be unreasonably withheld).

    Section  7.8  RULE  145 AFFILIATES.  Within  30 days after  the date of this
Agreement, NSP shall identify in  a letter to WEC, and  WEC shall identify in  a
letter to NSP, all persons who are, and to such person's best knowledge who will
be  at the Closing Date, "affiliates" of NSP and WEC, respectively, as such term
is used in Rule 145 under the Securities Act (or otherwise under applicable  SEC
accounting  releases with respect to pooling-of-interests accounting treatment).
Each of NSP and WEC shall use  all reasonable efforts to cause their  respective
affiliates  (including any person who may be  deemed to have become an affiliate
after the date of the  letter referred to in the  prior sentence) to deliver  to
each  other on or prior to the Closing Date a written agreement substantially in
the form attached as EXHIBIT 7.8 (each, an "AFFILIATE AGREEMENT").

    Section 7.9  EMPLOYEE AGREEMENTS AND WORKFORCE MATTERS.

    (a)  CERTAIN EMPLOYEE AGREEMENTS.  Subject to SECTION 7.10, SECTION 7.14 and
SECTION  7.15,  the   Company  and   its  subsidiaries   shall  honor,   without
modification,  all contracts,  agreements, collective  bargaining agreements and
commitments of the parties prior to the  date hereof which apply to any  current
or  former  employee  or  current  or former  director  of  the  parties hereto;
PROVIDED, HOWEVER, that this undertaking is not intended to prevent the  Company
from  enforcing such contracts, agreements, collective bargaining agreements and
commitments in accordance with their  terms, including, without limitation,  any
reserved right to amend, modify, suspend, revoke or terminate any such contract,
agreement, collective bargaining agreement or commitment.

    (b)    WORKFORCE  MATTERS.    Subject  to  applicable  collective bargaining
agreements, for  a period  of  three years  following  the Effective  Time,  any
reductions  in workforce in respect of employees of the Company shall be made on
a fair and equitable basis, in light of the circumstances and the objectives  to
be  achieved, giving consideration to previous work history, job experience, and
qualifications, without  regard  to  whether  employment was  with  NSP  or  its
subsidiaries  or WEC or its subsidiaries,  and any employees whose employment is
terminated or jobs  are eliminated  by the Company  or any  of its  subsidiaries
during  such period  shall be  entitled to participate  on a  fair and equitable
basis in the job  opportunity and employment placement  programs offered by  the
Company  or  any  of  its subsidiaries.  Any  workforce  reductions  carried out
following the Effective Time by the  Company and its subsidiaries shall be  done
in accordance with all applicable collective bargaining agreements, and all laws
and  regulations governing  the employment relationship  and termination thereof
including, without limitation, the Worker Adjustment and Retraining Notification
Act and regulations promulgated  thereunder, and any  comparable state or  local
law.

    Section 7.10  EMPLOYEE BENEFIT PLANS.

    (a)   MAINTENANCE OF NSP AND WEC BENEFIT PLANS.  Subject to SECTION 7.10(b),
Section 7.10(c)  and SECTION  6.1(i), each  of  the NSP  Benefit Plans  and  WEC
Benefit  Plans in effect at  the date hereof shall  be maintained in effect with
respect to  the employees  or former  employees of  NSP and  any of  its  Direct
Subsidiaries, on the one hand, and of WEC and any of its Direct Subsidiaries, on
the  other  hand,  respectively,  who  are  covered  by  any  such  benefit plan
immediately prior to  the Closing  Date (the "AFFILIATED  EMPLOYEES") until  the
Company  otherwise determines after the  Effective Time; PROVIDED, HOWEVER, that
nothing herein contained shall  limit any reserved right  contained in any  such
NSP  Benefit  Plan or  WEC Benefit  Plan  to amend,  modify, suspend,  revoke or
terminate any such  plan; PROVIDED, FURTHER,  HOWEVER, that the  Company or  its
subsidiaries  shall provide to the Affiliated Employees for a period of not less
than one year following the Effective Time benefits, other than with respect  to
plans  referred  to in  SECTION  7.10(b) and  SECTION  7.11, which  are  no less
favorable in the aggregate  than those provided under  the NSP Benefit Plans  or
the WEC Benefit Plans, as the case

                                      A-38
<PAGE>
may  be. Without limitation of  the foregoing, each participant  of any such NSP
Benefit  Plan  or  WEC  Benefit  Plan  shall  receive  credit  for  purposes  of
eligibility  to participate, vesting, benefit accrual and eligibility to receive
benefits under any benefit  plan of the  Company or any  of its subsidiaries  or
affiliates for service credited for the corresponding purpose under such benefit
plan;  PROVIDED, HOWEVER,  that such crediting  of service shall  not operate to
duplicate any  benefit to  any such  participant  or the  funding for  any  such
benefit.  Any person hired by  the Company or any  of its subsidiaries after the
Closing Date  who was  not employed  by  any party  hereto or  its  subsidiaries
immediately  prior to the Closing Date shall  be eligible to participate in such
benefit plans  maintained, or  contributed to,  by the  subsidiary, division  or
operation  by which such person is employed, PROVIDED that such person meets the
eligibility requirements of the applicable plan.

    (b)   ADOPTION  OF COMPANY  REPLACEMENT  PLANS.   With  respect to  the  WEC
Short-Term  Performance  Plan  (the  "WEC INCENTIVE  PLAN"),  the  NSP Executive
Incentive Compensation  Plan  (the  "NSP INCENTIVE  PLAN"),  the  NSP  Long-Term
Incentive Award Stock Plan (the "NSP STOCK PLAN") and the WEC 1993 Omnibus Stock
Incentive  Plan (the "WEC  STOCK PLAN"), the Company  and its subsidiaries shall
adopt replacement plans as set forth in this SECTION 7.10(b) (collectively,  the
"COMPANY REPLACEMENT PLANS"). Subject to shareholder approval thereof by the NSP
shareholders  and the  WEC shareholders, the  Company Replacement  Plans will go
into effect at  the Effective  Time. Upon the  consummation of  the Mergers,  no
additional  obligations shall be incurred under  the NSP Incentive Plan, the WEC
Incentive Plan, the WEC Stock Plan or  the NSP Stock Plan, except to the  extent
such  obligations are attributable to employment prior to the Effective Time and
are consistent with past practice under  the applicable plan. The WEC  Incentive
Plan  and  the NSP  Incentive Plan  shall  be replaced  (except with  respect to
obligations incurred or attributable to employment prior to the Effective  Time)
by  a new annual  bonus plan under  which cash bonuses,  based on percentages of
base salaries,  are awarded  based  upon the  achievement of  performance  goals
determined in advance by the Compensation Committee of the Board of Directors of
the  Company (the  "COMMITTEE"). With respect  to those participants  in the new
plan who  are,  or who  the  Committee determines  are  likely to  be,  "covered
individuals"  within the meaning of Section  162(m) of the Code, the performance
goals shall  be  objective  standards  that  are  approved  by  shareholders  in
accordance with the requirements for exclusion from the limits of Section 162(m)
of  the Code as performance-based  compensation. The NSP Stock  Plan and the WEC
Stock Plan shall  be replaced (except  with respect to  obligations incurred  or
attributable  to employment prior to the Effective Time) by a stock compensation
plan (the "COMPANY STOCK PLAN") providing for the grant of stock options,  stock
appreciation  rights,  restricted stock  and such  other  awards based  upon the
Company Common  Stock as  the Committee  may determine,  subject to  shareholder
approval  of the Company Stock Plan. The Company shall reserve 12 million shares
for issuance under the Company Stock Plan.

    (c)  NSP AND WEC  ACTION.  With respect to  each of the Company  Replacement
Plans,  each  of  NSP and  WEC  shall  take all  corporate  action  necessary or
appropriate to obtain the approval  of the respective shareholders with  respect
to  such plan prior to the Effective  Time. Before the Effective Time, WEC shall
take all steps necessary to amend (i) the WEC Supplemental Executive  Retirement
Plan, (ii) the WEC Executive Non-Qualified Trust, (iii) each of the Supplemental
Retirement Benefit Agreements set forth in Section 5.10(g) of the WEC Disclosure
Schedule,  (iv)  the  WEC  Executive Deferred  Compensation  Plan,  (v)  the WEC
Directors' Deferred Compensation  Plan, and (vi)  the WEPCO Directors'  Deferred
Compensation  Plan,  so  that  none of  the  transactions  contemplated  by this
Agreement  shall  constitute  a   Change  of  Control   for  purposes  of   said
arrangements,  PROVIDED that with respect to items (iii) through (vi), WEC shall
use its best efforts to obtain the  consent of the other parties thereto.  Prior
to  or as soon as practicable  after the date hereof, each  of NSP and WEC shall
adopt severance plans  substantially in  the forms attached  hereto as  EXHIBITS
7.10(a) and 7.10(b), respectively.

    Section 7.11  STOCK OPTION AND OTHER STOCK PLANS.

    (a)    AMENDMENT OF  NSP STOCK  PLAN AND  AGREEMENTS.   Effective as  of the
Effective Time, NSP  shall amend the  NSP Stock Plan  and each underlying  award
agreement to provide that (i) each

                                      A-39
<PAGE>
outstanding  option to  purchase shares  of Old NSP  Common Stock  (each, a "NSP
STOCK OPTION"), along with any tandem stock appreciation right, shall constitute
an option to  acquire shares  of Company  Common Stock,  on the  same terms  and
conditions  as were applicable  under such NSP  Stock Option, based  on the same
number of shares of  the Company Common  Stock as the holder  of such NSP  Stock
Option  would  have been  entitled  to receive  pursuant  to the  NSP  Merger in
accordance with  ARTICLE  II had  such  holder  exercised such  option  in  full
immediately  prior to the  Effective Time; PROVIDED, that  the number of shares,
the option price, and the terms and conditions of exercise of such option, shall
be determined in a manner that preserves  both (A) the aggregate gain (or  loss)
on  the NSP  Stock Option immediately  prior to  the Effective Time  and (B) the
ratio of the exercise  price per share  subject to the NSP  Stock Option to  the
fair market value (determined immediately prior to the Effective Time) per share
subject to such option; and PROVIDED, FURTHER, that in the case of any option to
which  Section 421 of the Code applies  by reason of its qualification under any
of Sections  422-424  of  the Code,  the  option  price, the  number  of  shares
purchasable  pursuant to such option and the terms and conditions of exercise of
such option shall be determined  in order to comply  with Section 424(a) of  the
Code; and (ii) each other outstanding award under the NSP Stock Plan ("NSP STOCK
AWARDS")  shall constitute  an award  based upon  the same  number of  shares of
Company Common Stock  as the  holder of  such NSP  Stock Award  would have  been
entitled to receive pursuant to the NSP Merger in accordance with ARTICLE II had
such  holder been the absolute owner,  immediately before the Effective Time, of
the shares of  NSP Common  Stock on  which such NSP  Stock Award  is based,  and
otherwise  on the  same terms  and conditions as  governed such  NSP Stock Award
immediately before the Effective Time. At the Effective Time, the Company  shall
assume  each  stock award  agreement relating  to  the NSP  Stock Plan,  each as
amended as previously provided. As soon as practicable after the Effective Time,
the Company shall  deliver to the  holders of  NSP Stock Options  and NSP  Stock
Awards  appropriate notices setting  forth such holders'  rights pursuant to the
Company Stock Plan and each underlying stock award agreement, each as assumed by
the Company.

    (b)   AMENDMENT OF  WEC STOCK  PLAN AND  AGREEMENTS.   Effective as  of  the
Effective  Time, WEC shall amend the WEC Stock  Plan and use its best efforts to
amend each  underlying  stock  award  agreement to  provide  that  none  of  the
transactions contemplated by this Agreement shall constitute a Change in Control
for purposes of the WEC Stock Plan.

    (c)   COMPANY ACTION.  With  respect to each of the  NSP Stock Plan, the WEC
Stock Plan, the  NSP Employee  Stock Ownership Plan  and any  other plans  under
which  the delivery of Old NSP Common  Stock, WEC Common Stock or Company Common
Stock is  required upon  payment of  benefits, grant  of awards  or exercise  of
options  (the  "STOCK  PLANS"),  the Company  shall  take  all  corporate action
necessary or appropriate to (i) obtain shareholder approval with respect to such
Stock Plan to the extent such approval  is required for purposes of the Code  or
other  applicable law, or  to enable such  Stock Plan to  comply with Rule 16b-3
promulgated under the Exchange Act, (ii) reserve for issuance under such plan or
otherwise provide a  sufficient number  of shares  of Company  Common Stock  for
delivery  upon payment of benefits, grant of awards or exercise of options under
such Stock Plan and (iii) as soon as practicable after the Effective Time,  file
registration  statements on  Form S-3 or  Form S-8, as  the case may  be (or any
successor or other  appropriate forms), with  respect to the  shares of  Company
Common  Stock  subject  to  such  Stock Plan  to  the  extent  such registration
statement is required under applicable law,  and the Company shall use its  best
efforts  to  maintain the  effectiveness  of such  registration  statements (and
maintain the current status of the  prospectuses contained therein) for so  long
as  such benefits and grants remain payable and such options remain outstanding.
With respect to those individuals who subsequent to the Mergers will be  subject
to  the  reporting requirements  under Section  16(a) of  the Exchange  Act, the
Company shall administer  the Stock Plans,  where applicable, in  a manner  that
complies with Rule 16b-3 promulgated under the Exchange Act.

    Section  7.12  NO SOLICITATIONS.  No party hereto shall, and each such party
shall cause  its  Direct  Subsidiaries not  to,  shall  not permit  any  of  its
Representatives  or subsidiaries that are not  Direct Subsidiaries to, and shall
use its  best efforts  to cause  such persons  not to,  directly or  indirectly:

                                      A-40
<PAGE>
initiate,  solicit or encourage, or take any  action to facilitate the making of
any offer or proposal which constitutes or is reasonably likely to lead to,  any
Business  Combination  Proposal  (as defined  below),  or,  in the  event  of an
unsolicited Business  Combination Proposal,  except to  the extent  required  by
their  fiduciary duties under applicable law if  so advised in a written opinion
of outside counsel, engage in negotiations or provide any information or data to
any person  relating to  any Business  Combination Proposal.  Each party  hereto
shall notify the other party orally and in writing of any such inquiries, offers
or  proposals (including,  without limitation, the  terms and  conditions of any
such proposal and the identity of the person making it), within 24 hours of  the
receipt  thereof, shall keep the other party  informed of the status and details
of any such  inquiry, offer or  proposal, and  shall give the  other party  five
days' advance notice of any agreement to be entered into with or any information
to  be supplied to any person making such inquiry, offer or proposal. Each party
hereto  shall  immediately  cease  and  cause  to  be  terminated  all  existing
discussions and negotiations, if any, with any parties conducted heretofore with
respect  to any  Business Combination  Proposal. As  used in  this SECTION 7.12,

to consummate  the Mergers  in accordance  with the  terms hereof.  The  parties
expressly  acknowledge and agree that, although it is their current intention to
effect a business combination among themselves in the form contemplated by  this

SECTION  8.1(e),  SECTION 8.2(e),  SECTION 8.2(f),  SECTION 8.3(e),  and SECTION

or more of  the NSP  Required Consents,  NSP Required  Statutory Approvals,  WEC
Required Consents, WEC Required Statutory Approvals or the ruling referred to in
SECTIONS  8.2(e) and 8.3(e), and the  adoption of an alternative structure (that
otherwise substantially preserves for NSP and  WEC the economic benefits of  the
Merger)  would result  in such  conditions being  satisfied or  waived, then the
parties shall use their respective best efforts to effect a business combination
among themselves by  means of a  mutually agreed upon  structure other than  the
Mergers  that so  preserves such benefits;  PROVIDED that, prior  to closing any
such  restructured  transaction,  all  material  third  party  and  Governmental
Authority   declarations,   filings,  registrations,   notices,  authorizations,
consents or  approvals  necessary  for  the  effectuation  of  such  alternative
business  combination shall have  been obtained and all  other conditions to the
parties' obligations to consummate the  Mergers, as applied to such  alternative
business combination, shall have been satisfied or waived.

<PAGE>
offeror or a subsidiary  of an affiliate  of such offeror  or accepts a  written
offer  to consummate or consummates a  Business Combination with such offeror or
an affiliate thereof, then such breaching party (jointly and severally with  its

third  party, and (iii)  within two and  one-half years of  any such termination
described in clause (i) above, the party  or its affiliate which is the  subject

(the "TARGET PARTY") becomes a subsidiary of such offeror or a subsidiary of  an
affiliate  of  such  offeror  or  accepts  a  written  offer  to  consummate  or
consummates a Business Combination with such offeror or affiliate thereof,  then
such  Target Party (jointly and severally with its affiliates), upon the signing
of a definitive  agreement relating to  such a Business  Combination, or, if  no
such  agreement  is signed,  then  at the  closing (and  as  a condition  to the
closing) of such  Target Party becoming  such a subsidiary  or of such  Business
Combination,  will pay to the other party a termination fee equal to $75 million
in cash plus the out-of-pocket fees  and expenses incurred by the  non-breaching
party  (including, without limitation,  fees and expenses  payable to all legal,
accounting, financial, public relations and other professional advisors  arising

SECTION  9.3  are  an integral  part  of  the transactions  contemplated  by the
Agreement and constitute  liquidated damages  and not  a penalty.  If one  party
fails  to promptly pay to the other  any fee due hereunder, the defaulting party

purposes of this SECTION 9.3(d), the amount payable pursuant to the terms of the
WEC Stock Option Agreement or  the NSP Stock Option  Agreement, as the case  may
be, shall be the amount paid pursuant to Section 7(a)(i) and 7(a)(ii) thereof.

Directors of the parties hereto, at any time before or after approval hereof  by
the  shareholders of NSP and WEC and prior to the Effective Time, but after such

effect to its conflicts of law, rules or principles and except to the extent the

shall be deemed to be followed by the words "without limitation".

    Section  10.6  COUNTERPARTS; EFFECT.  This  Agreement may be executed in one
or more counterparts, each of which shall  be deemed to be an original, but  all
of which shall constitute one and the same agreement.

    Section 10.7  PARTIES IN INTEREST.  This Agreement shall be binding upon and
inure  solely to  the benefit of  each party  hereto, and, except  for rights of
Indemnified Parties as  set forth  in SECTION  7.5, nothing  in this  Agreement,
express  or implied, is intended  to confer upon any  other person any rights or
remedies of  any  nature  whatsoever  under or  by  reason  of  this  Agreement.
Notwithstanding  the foregoing and any other provision of this Agreement, and in
addition to any other required action of  the Board of Directors of the  Company
(a)  a majority of the  directors (or their successors)  serving on the Board of
Directors of the  Company who  are designated by  WEC pursuant  to SECTION  7.13

(the "THREE YEAR  PERIOD") to  enforce the  provisions of  SECTION 7.9,  SECTION
7.10, SECTION 7.11 and SECTION 7.14 on behalf of the WEC officers, directors and
employees,  as the case  may be, and (b)  a majority of  the directors (or their

SECTION 7.14 on behalf of the NSP officers, directors and employees, as the case
may  be. Such  directors' rights and  remedies under the  preceding sentence are
cumulative and are in addition to any other rights and remedies they may have at
law or in equity, but  in no event shall this  SECTION 10.7 be deemed to  impose
any  additional duties on any such directors. The Company shall pay, at the time
they are incurred, all  costs, fees and expenses  of such directors incurred  in
connection  with the assertion of any rights  on behalf of the persons set forth
above pursuant to this SECTION 10.7.

    Section 10.8  WAIVER OF JURY TRIAL AND CERTAIN DAMAGES.  Each party to  this
Agreement  waives, to  the fullest extent  permitted by applicable  law, (i) any
right it  may  have to  a  trial by  jury  in respect  of  any action,  suit  or
proceeding  arising  out  of or  relating  to  this Agreement  and  (ii) without
limitation to SECTION 9.3,  any right it  may have to  receive damages from  any
other  party  based  on  any  theory of  liability  for  any  special, indirect,
consequential (including lost profits) or punitive damages.

    Section 10.9  ENFORCEMENT.  The parties agree that irreparable damage  would
occur  in  the event  that  any of  the provisions  of  this Agreement  were not
performed in accordance with their specific terms or were otherwise breached. It
is accordingly agreed  that the parties  shall be entitled  to an injunction  or
injunctions  to prevent breaches  of this Agreement  and to enforce specifically
the terms and provisions  of this Agreement  in any court  of the United  States
located  in the  State of New  York or  in New York  state court,  this being in
addition to any other remedy to which they are entitled at law or in equity.  In
addition,  each  of the  parties hereto  (a)  consents to  submit itself  to the
personal jurisdiction of any federal court located  in the State of New York  or
any  New York state court in the event  any dispute arises out of this Agreement
or any of the  transactions contemplated by this  Agreement, (b) agrees that  it
will  not attempt to deny such personal  jurisdiction by motion or other request
for leave from any such court and (c)  agrees that it will not bring any  action
relating  to  this Agreement  or any  of the  transactions contemplated  by this
Agreement in any court other than a federal or state court sitting in the  State

                          FORM OF AFFILIATE AGREEMENT

GENTLEMEN:

    [The undersigned is a holder of shares of [Common Stock, par value $2.50 per
share  ("NSP  COMMON  STOCK"), of  Northern  States Power  Company,  a Minnesota
corporation ("NSP")]  [Common  Stock, par  value  $.01 per  share  ("WEC  COMMON
STOCK")  of  Wisconsin  Energy  Corporation,  a  Wisconsin  corporation ("WEC")]
[Cumulative Preferred Stock, par value $100 per share ("NSP PREFERRED STOCK") of
Northern States  Power  Company,  a Minnesota  corporation  ("NSP")]  [Preferred
Stock,  par value $100 per share ("WEPCO PREFERRED STOCK") of Wisconsin Electric
Power Company, a Wisconsin corporation ("WEPCO")]]. [The undersigned is entitled
to receive in connection with  the merger (the "MERGER")  of [NSP], after it  is
reincorporated  in Wisconsin, with a subsidiary of [WEC], securities of WEC (the
"Securities").] [This  letter relates  to the  merger (the  "Merger") of  [NSP],
after  it is reincorporated in  Wisconsin, with a subsidiary  of [WEC], in which
holders  of   securities  of   NSP  shall   receive  securities   of  WEC   (the
"Securities").]

    The   undersigned  acknowledges  that  the  undersigned  may  be  deemed  an
"affiliate" of  [NSP]  [WEC]  within  the  meaning  of  Rule  145  ("RULE  145")
promulgated  under the Securities Act of 1933, as amended (the "ACT"), and/or as
such term is used in and for purposes of Accounting Series Releases 130 and 135,
as amended,  of  the  Securities and  Exchange  Commission  (the  "Commission"),
although  nothing contained  herein shall be  construed as an  admission of such
status.

    If in fact the undersigned were an  affiliate of [NSP] [WEC] under the  Act,
the  undersigned's ability to sell, assign  or transfer any Securities [received
by the undersigned in exchange  for any shares of  NSP Common Stock pursuant  to
the  Merger] may be  restricted unless such transaction  is registered under the
Act or  an  exemption  from  such registration  is  available.  The  undersigned
understands  that such exemptions  are limited and  the undersigned has obtained
advice of counsel as to the nature and conditions of such exemptions,  including
information  with respect to the applicability to the sale of such securities of
Rules 144 and 145(d) promulgated under the Act.

    The undersigned hereby represents to and covenants with [WEC] [NSP] that  it
will not sell, assign or transfer any Securities [received by the undersigned in
exchange  for shares  of NSP  Common Stock  pursuant to  the Merger]  except (i)
pursuant to an effective  registration statement under the  Act, (ii) by a  sale
made  in  conformity with  the volume  and  other limitations  of Rule  145 (and
otherwise in accordance with  Rule 144 under  the Act if  the undersigned is  an
affiliate  of WEC  and if  so required at  the time)  or (iii)  in a transaction
which, in the opinion of independent  counsel reasonably satisfactory to WEC  or
as  described in  a "no-action"  or interpretive  letter from  the Staff  of the
Commission, is not required to be registered under the Act.

    The undersigned understands that WEC is under no obligation to register  the
sale,  transfer or other disposition of the  Securities by the undersigned or on
behalf of the undersigned under the Act or to take any other action necessary in
order to  make compliance  with an  exemption from  such registration  available
solely as a result of the Merger.

    In  the event of a sale of  Securities pursuant to Rule 145, the undersigned
will supply WEC  with evidence  of compliance  with such  Rule, in  the form  of
customary  seller's and broker's  Rule 145 representation letters  or as WEC may
otherwise reasonably request. The undersigned understands that WEC may  instruct
its transfer agent to withhold the transfer of any Securities disposed of by the
undersigned in a manner inconsistent with this letter.

    The  undersigned acknowledges  and agrees  that appropriate  legends will be
placed on certificates  representing Securities received  by the undersigned  in
the Merger or held by a transferee thereof, which legends will be removed (i) by
delivery  of  substitute certificates  upon receipt  of an  opinion in  form and
substance reasonably satisfactory to WEC to the effect that such legends are  no
longer

required  for  the purposes  of the  Act and  the rules  and regulations  of the
Commission promulgated  thereunder  or  (ii) in  the  event  of a  sale  of  the
Securities  which has been registered  under the Act or  made in conformity with
the provisions of Rule 145.

    The undersigned  further represents  to,  and covenants  with WEC  that  the
undersigned  will not,  during the 30  days prior  to the effective  time of the
Merger sell, transfer or otherwise dispose  of, or reduce any risk relative  to,
any securities of WEPCO, NSP or WEC, and the undersigned will not sell, transfer
or otherwise dispose of, or reduce any risk relative to, the Securities received
by the undersigned in the Merger or any other shares of the capital stock of WEC
until  after such time as results covering at least 30 days of operations of WEC
(including the combined operations of NSP and WEC) have been published by WEC in
the form of  a quarterly  earnings report, an  effective registration  statement
filed  with the Commission,  a report to  the Commission on  Form 10-K, 10-Q, or
8-K, or any other public filing  or announcement which includes such results  of
operations.

    The  undersigned acknowledges that it has carefully reviewed this letter and
understands the  requirements  hereof  and  the  limitations  imposed  upon  the
distribution, sale, transfer or other disposition of Securities.

                                          Very truly yours,
                                          ______________________________________

    As  an inducement to the above individual to deliver this letter, WEC agrees
that for so long  as and to  the extent necessary to  permit such individual  to
sell the Securities pursuant to Rule 145 and, to the extent applicable, Rule 144
under  the Act, WEC shall use all reasonable efforts to file, on a timely basis,
all reports and data required to be filed by it with the Commission pursuant  to
Section 13 of the Securities Exchange Act of 1934.

                     NSP SENIOR EXECUTIVE SEVERANCE POLICY
                                  INTRODUCTION

    Northern States Power Company, a Minnesota corporation ("NSP") and Wisconsin
Energy  Corporation,  a  Wisconsin  corporation  ("WEC")  have  entered  into an
Agreement  and  Plan  of  Merger  dated  as  of  April  28,  1995  (the  "Merger
Agreement"),   whereby  the  NSP   and  WEC  organizations   will  engage  in  a
merger-of-equals transaction (the "Combination"). The Board of Directors of  NSP
recognizes  that the pendency of the Combination, and the inevitable adjustments
that will  occur during  the transition  period following  the Combination,  may
result  in  the loss  or distraction  of  employees of  the Corporation  and its
Subsidiaries to the detriment of the Corporation and its shareholders.

    The Board  considers  the avoidance  of  such  loss and  distraction  to  be
essential  to protecting and enhancing the best interests of the Corporation and
its shareholders.  The Board  also  believes that  during  the pendency  of  the
Combination  and the transition  period thereafter, the Board  should be able to
receive and rely on  disinterested service from  employees without concern  that
employees might be distracted or concerned by personal uncertainties and risks.

    In addition, the Board believes that it is consistent with the Corporation's
employment  practices and policies and in  the best interests of the Corporation
and its shareholders to treat  fairly its employees whose employment  terminates
in connection with or following the Combination.

    Accordingly, the Board has determined that appropriate steps should be taken
to  assure  the  Corporation  of  the  continued  employment  and  attention and
dedication to duty of its  employees and to seek  to ensure the availability  of
their continued service, notwithstanding the Combination.

    Therefore,  in order to  fulfill the above purposes,  the following plan has
been developed and is hereby adopted.

                                   ARTICLE I

    4.2  TERMINATION OF EMPLOYMENT.

    (a)    TERMINATIONS  WHICH  GIVE  RISE  TO  SEPARATION  BENEFITS  UNDER THIS
PLAN.  Except  as set  forth in  subsection (b)  below, a  Participant shall  be
entitled to Separation Benefits if, at any time before the second anniversary of
the Date of the Combination:

        (i)  the Participant ceases to be an  Employee by action of the Employer
    or any of its affiliates (excluding any transfer to another Employer);

        (ii) the Participant's Annual Salary is reduced below the higher of  (x)
    the  amount in effect  on the Effective  Date and (y)  the highest amount in
    effect at any time thereafter, and the Participant ceases to be an  Employee
    by  his  or her  own  action within  90 days  after  the occurrence  of such
    reduction;

       (iii) the Participant's  duties and  responsibilities or  the program  of
    incentive  compensation and retirement  and welfare benefits  offered to the
    Participant are materially  and adversely  diminished in  comparison to  the
    duties  and  responsibilities  or the  program  of benefits  enjoyed  by the
    Participant on  the Effective  Date, and  the Participant  ceases to  be  an
    Employee  by his or her own action within 90 days after the occurrence after
    such reduction;

       (iv) the Participant is required to be  based at a location more than  50
    miles  from  the  location where  the  Participant was  based  and performed
    services on the Effective Date, and the Participant ceases to be an Employee
    by his or her own action within 90 days after such relocation;

        (v) an  Employer or  any affiliate  of an  Employer sells  or  otherwise
    distributes  or disposes of the subsidiary, branch or other business unit in
    which the  Participant  was  employed  before  such  sale,  distribution  or
    disposition  and the requirements of subsection  (b)(iv) of this Section 4.2
    are not met, and the Participant ceases to be an Employee upon or within  90
    days after such sale, distribution or disposition.

    (b)   TERMINATIONS WHICH DO NOT GIVE  RISE TO SEPARATION BENEFITS UNDER THIS
PLAN.   If  a Participant's  employment  is terminated  for  Cause,  disability,
retirement,  or a qualified sale of business (as those terms are defined below),
or voluntarily  by the  Participant in  the  absence of  an event  described  in
subsection (a)(ii), (iii) or (iv) of this Section 4.2, the Participant shall not
be entitled to Separation Benefits under the Plan.

        (i) A termination for disability shall have occurred where a Participant
    is  terminated because illness  or injury has  prevented him from performing
    his duties (as they existed immediately prior to the illness or injury) on a
    full time basis for 180 consecutive business days.

        (ii)  A  termination   by  retirement  shall   have  occurred  where   a
    Participant's  termination is  due to  his voluntary  late, normal  or early
    retirement under a pension plan sponsored by his Employer or its affiliates,
    as defined in such plan.

       (iii) A termination for Cause shall have occurred where a Participant  is
    terminated because of:

           (A)  the willful and continued failure  of the Participant to perform
       substantially the Participant's duties with the Corporation or one of its
       affiliates (other than any such failure resulting from incapacity due  to
       physical  or  mental illness),  after  a written  demand  for substantial
       performance is delivered to  the Participant by the  Board or an  elected
       officer of

                                      A-59
<PAGE>
       the  Corporation which  specifically identifies  the manner  in which the
       Board or  the  elected officer  believes  that the  Participant  has  not
       substantially performed the Participant's duties, or

           (B)  the willful  engaging by the  Participant in  illegal conduct or
       gross misconduct which  is materially and  demonstrably injurious to  the
       Corporation.

    For purposes of this provision, no act or failure to act, on the part of the
    Participant,  shall be considered "willful" unless it is done, or omitted to
    be done, by the Participant in  bad faith or without reasonable belief  that
    the  Participant's  action or  omission  was in  the  best interests  of the
    Corporation. Any act, or failure to act, based upon authority given pursuant
    to a resolution duly adopted by the Board, or upon the advice of counsel for
    the Corporation, shall be conclusively presumed to be done, or omitted to be
    done, by the  Participant in good  faith and  in the best  interests of  the
    Corporation.

       (iv)  A  termination  due to  a  qualified  sale of  business  shall have
    occurred where  an  Employer  or  an affiliate  of  an  Employer  has  sold,
    distributed  or  otherwise  disposed  of  the  subsidiary,  branch  or other
    business unit  in  which the  Participant  was employed  before  such  sale,
    distribution  or disposition and the Participant has been offered employment
    with the purchaser of such subsidiary, branch or other business unit or  the
    corporation  or other entity which is the owner thereof on substantially the
    same terms and conditions under which he worked for the Employer (including,
    without limitation,  base salary,  duties and  responsibilities, program  of
    benefits  and location  where based). Such  terms and  conditions shall also
    include, without limitation,  a legally binding  agreement or plan  covering
    such  Participant, providing that upon a  termination of employment with the
    subsidiary, branch  or business  unit (or  the corporation  or other  entity
    which  is the owner thereof) or any  successor thereto of the kind described
    in Article VI of this Plan, at any time before the second anniversary of the
    Date of the Combination,  the Participant's employer  or any successor  will
    pay  to  each such  former  Participant an  amount  equal to  the separation
    benefit and other benefits that such former Participant would have  received
    under  the Plan had he  been a Participant at  the time of such termination.
    For purposes of  this subsection, the  new employer plan  or agreement  must
    treat service with any Employer (irrespective of whether the Employer was an
    affiliate  of the Corporation or the Employee  was a Participant at the time
    of such service) and the new employer as continuous service for purposes  of
    calculating separation benefits.

    4.3  SEPARATION BENEFITS.

    (a)  If a Participant's employment  is terminated in circumstances entitling
him to a  separation benefit as  provided in Section  4.2(a), the  Participant's
Employer shall pay such Participant, within ten days of the Date of Termination,
a  cash lump sum as set forth in subsection (b) below and the continued benefits
set forth in subsection (c) below. For purposes of determining the benefits  set
forth  in  subsections (b)  and  (c), if  the  termination of  the Participant's
employment is  based upon  a reduction  of the  Participant's Annual  Salary  or
benefits as described in subsection (ii) or (iii) of Section 4.2, such reduction
shall be ignored.

    (b)  The  cash  lump sum  referred  to  in Section  4.3(a)  shall  equal the
aggregate of the following amounts:

        (i) the sum of (1) the  Participant's Annual Salary through the Date  of
    Termination  to the extent not theretofore paid,  (2) the product of (x) the
    Target Incentive and (y) a fraction, the numerator of which is the number of
    days in such year  through the Date of  Termination, and the denominator  of
    which   is  365,  and  (3)  any  compensation  previously  deferred  by  the
    Participant (together with any accrued interest or earnings thereon) and any
    accrued vacation pay, in each case to the extent not theretofore paid and in
    full satisfaction of the rights of the Participant thereto;

                                      A-60
<PAGE>
        (ii) an amount equal to the product of (1) three and (2) the sum of  (x)
    the  Participant's Annual  Salary and  (y) the  higher of  the Target Annual
    Incentive or the Annual Incentive Award; and

       (iii) an  amount  equal  to  the difference  between  (a)  the  actuarial
    equivalent  of the benefit under the Corporation's qualified defined benefit
    retirement plan  (the  "Retirement Plan")  and  any excess  or  supplemental
    retirement  plans  in  which  the  Participant  participates  (together, the
    "SERP") which  the  Participant  would  receive if  his  or  her  employment
    continued  during  the Separation  Period,  assuming that  the Participant's
    compensation during the Separation  Period would have been  equal to his  or
    her  compensation as  in effect  immediately before  the termination  or, if
    higher, on  the Effective  Date, and  (b) the  actuarial equivalent  of  the
    Participant's actual benefit (paid or payable), if any, under the Retirement
    Plan  and the SERP as of the  Date of Termination. The actuarial assumptions
    used for  purposes of  determining actuarial  equivalence shall  be no  less
    favorable  to the  Participant than  the most  favorable of  those in effect
    under the Retirement Plan and  the SERP on the  Date of Termination and  the
    Effective Date.

    (c) The continued benefits referred to above shall be as follows.

        (i)  During the Separation Period, the  Participant and his family shall
    be provided  with medical,  dental and  life insurance  benefits as  if  the
    Participant's employment had not been terminated; provided, however, that if
    the  Participant becomes reemployed with another employer and is eligible to
    receive medical or  other welfare benefits  under another  employer-provided
    plan,  the  medical and  other welfare  benefits  described herein  shall be
    secondary to those  provided under  such other plan  during such  applicable
    period  of eligibility. For purposes of determining eligibility (but not the
    time of commencement of  benefits) of the  Participant for retiree  medical,
    dental and life insurance benefits under the Corporation's plans, practices,
    programs  and policies, the Participant shall be considered to have remained
    employed during the Separation Period and to have retired on the last day of
    such period;

        (ii) The Corporation shall, at its sole expense as incurred, provide the
    Participant with outplacement services the scope and provider of which shall
    be selected by the Participant in his or her sole discretion (but at a  cost
    to  the  Corporation of  not  more than  $30,000)  or, at  the Participant's
    option,  the  use  of  office  space,  office  supplies  and  equipment  and
    secretarial services for a period not to exceed one year;

       (iii)  The  Corporation shall  continue to  provide the  Participant with
    financial planning counselling  benefits through the  second anniversary  of
    the  Date of Termination, on the same terms and conditions as were in effect
    immediately before the termination or,  if more favorable, on the  Effective
    Date; and

       (iv) The Corporation shall transfer to the Participant, at no cost to the
    Participant,  the title to the company car  being used by the Participant as
    of the Date of Termination.

To the extent any benefits described  in this Section 4.3(c) cannot be  provided
pursuant  to  the  appropriate plan  or  program maintained  for  Employees, the
Employer shall  provide  such  benefits  outside such  plan  or  program  at  no
additional cost (including without limitation tax cost) to the Participant.

    4.4   OTHER  BENEFITS PAYABLE.   The cash  lump sum  and continuing benefits
described in Section 4.3 above shall be payable in addition to, and not in  lieu
of,  all other  accrued or vested  or earned but  deferred compensation, rights,
options or other benefits which may be  owed to a Participant upon or  following
termination,  including but not limited to accrued vacation or sick pay, amounts
or benefits payable under  any bonus or other  compensation plans, stock  option
plan,  stock ownership  plan, stock purchase  plan, life  insurance plan, health
plan, disability plan or similar or successor plan, but excluding any  severance
pay  or pay  in lieu  of notice required  to be  paid to  such Participant under
applicable law.

    4.5  CERTAIN REDUCTION OF PAYMENTS BY THE CORPORATION.

    (a) For purposes of this Section 4.5,  (i) a Payment shall mean any  payment
or  distribution  in the  nature  of compensation  to or  for  the benefit  of a
Participant, whether paid or  payable pursuant to this  Plan or otherwise;  (ii)
Separation  Payment shall mean a  Payment paid or payable  pursuant to this Plan
(disregarding this Section); (iii) Net After Tax Receipt shall mean the  Present
Value  of  a Payment  net of  all taxes  imposed on  a Participant  with respect
thereto under Sections  1 and  4999 of  the Internal  Revenue Code  of 1986,  as
amended  (the "Code"),  determined by applying  the highest  marginal rate under
Section 1 of the Code which applied to the Participant's taxable income for  the
immediately  preceding taxable year; (iv) "Present  Value" shall mean such value
determined in accordance with Section 280G(d)(4)  of the Code; and (v)  "Reduced
Amount"  shall mean the  greatest aggregate amount  of Separation Payments which
(a) is less than the sum of all Separation Payments and (b) results in aggregate
Net After Tax  Receipts which are  equal to or  greater than the  Net After  Tax
Receipts  which  would  result if  the  Participant  were paid  the  sum  of all
Separation Payments.

    (b) Anything in this Agreement to the contrary notwithstanding, in the event
Price Waterhouse or such  other certified public  accounting firm designated  by
the  Participant (the  "Accounting Firm")  shall determine  that receipt  of all
Payments would subject the Participant to tax under Section 4999 of the Code, it
shall determine  whether  some amount  of  Separation Payments  would  meet  the
definition  of a "Reduced Amount." If  the Accounting Firm determines that there
is a Reduced Amount, the aggregate Separation Payments shall be reduced to  such
Reduced  Amount. All fees payable to the Accounting Firm shall be paid solely by
the Corporation.

    (c) If the  Accounting Firm  determines that  aggregate Separation  Payments
should be reduced to the Reduced Amount, the Corporation shall promptly give the
Participant  notice  to  that effect  and  a  copy of  the  detailed calculation
thereof, and the Participant may then  elect, in his sole discretion, which  and
how  much of the Separation Payments shall  be eliminated or reduced (as long as
after such  election the  present  value of  the aggregate  Separation  Payments
equals  the Reduced Amount), and shall advise  the Corporation in writing of his
election within ten days of his receipt  of notice. If no such election is  made
by  the Participant within such ten-day  period, the Corporation may elect which
of such Separation  Payments shall be  eliminated or reduced  (as long as  after
such  election the present value of the aggregate Separation Payments equals the
Reduced Amount) and shall notify the Participant promptly of such election.  All
determinations  made by the Accounting Firm  under this Section shall be binding
upon the Corporation and the Participant and  shall be made within 60 days of  a
termination  of  employment  of  the  Participant.  As  promptly  as practicable
following such determination, the Corporation shall pay to or distribute for the
benefit of  the Participant  such Separation  Payments as  are then  due to  the
Participant  under this  Plan and  shall promptly pay  to or  distribute for the
benefit of the Participant in the future such Separation Payments as become  due
to the Participant under this Plan.

    (d)  While it  is the  intention of  the Corporation  to reduce  the amounts
payable or distributable to the Participants hereunder only if the aggregate Net
After Tax Receipts to a Participant would  thereby be increased, as a result  of
the  uncertainty in the application  of Section 4999 of the  Code at the time of
the initial determination by the Accounting Firm hereunder, it is possible  that
amounts  will have  been paid or  distributed by  the Corporation to  or for the
benefit of a Participant  pursuant to this  Plan which should  not have been  so
paid  or distributed ("Overpayment") or that  additional amounts which will have
not been paid  or distributed  by the  Corporation to or  for the  benefit of  a
Participant  pursuant  to  this Plan  could  have  been so  paid  or distributed
("Underpayment"), in each case, consistent  with the calculation of the  Reduced
Amount  hereunder.  In  the  event  that the  Accounting  Firm,  based  upon the
assertion of a  deficiency by the  Internal Revenue Service  against either  the
Corporation  or the  Participant which the  Accounting Firm believes  has a high
probability of success determines  that an Overpayment has  been made, any  such
Overpayment  paid or distributed by  the Corporation to or  for the benefit of a
Participant shall be treated for all purposes as a loan to the Participant which
the Participant shall  repay to the  Corporation together with  interest at  the
applicable  federal  rate  provided  for  in  Section  7872(f)(2)  of  the Code;
provided, however, that no such loan

                                      A-62
<PAGE>
shall be  deemed  to  have been  made  and  no  amount shall  be  payable  by  a
Participant to the Corporation if and to the extent such deemed loan and payment
would  not either reduce the  amount on which the  Participant is subject to tax
under Section 1 and Section 4999 of the Code or generate a refund of such taxes.
In the  event that  the Accounting  Firm, based  upon controlling  precedent  or
substantial  authority, determines that  an Underpayment has  occurred, any such
Underpayment shall be promptly paid by the Corporation to or for the benefit  of
the  Participant together with interest at  the applicable federal rate provided
for in Section 7872(f)(2) of the Code.

    4.6  PAYMENT OBLIGATIONS ABSOLUTE.  Subject to Section 4.5, the  obligations
of the Corporation and the Employers to pay the separation benefits described in
Section 4.3 shall be absolute and unconditional and shall not be affected by any
circumstances,   including,  without  limitation,   any  set-off,  counterclaim,
recoupment, defense  or  other  right  which  the  Corporation  or  any  of  its
Subsidiaries  may have against any Participant.  In no event shall a Participant
be obligated  to seek  other  employment or  take any  other  action by  way  of
mitigation  of the amounts payable to a  Participant under any of the provisions
of this Plan, nor shall  the amount of any payment  hereunder be reduced by  any
compensation  earned  by a  Participant  as a  result  of employment  by another
employer, except as specifically provided in Section 4.3(c)(i).

                                   ARTICLE V
                            PARTICIPATING EMPLOYERS

    This Plan may  be adopted by  any Subsidiary of  the Corporation. Upon  such
adoption,  the Subsidiary shall become an  Employer hereunder and the provisions
of the Plan shall be  fully applicable to the  Employees of that Subsidiary  who
are Participants pursuant to Section 3.1.

                                   ARTICLE VI
                            SUCCESSOR TO CORPORATION

    This  Plan shall bind  any successor of  the Corporation, its  assets or its
businesses (whether direct  or indirect, by  purchase, merger, consolidation  or
otherwise),  including without limitation Northern Power Wisconsin Corp., in the
same manner and to the same extent that the Corporation would be obligated under
this Plan if no succession had taken place.

    In the  case of  any  transaction in  which a  successor  would not  by  the
foregoing  provision  or  by  operation  of  law  be  bound  by  this  Plan, the
Corporation shall require such successor expressly and unconditionally to assume
and agree to perform the Corporation's obligations under this Plan, in the  same
manner  and to the same extent that the Corporation would be required to perform
if no such succession had taken place.  The term "Corporation," as used in  this
Plan,  shall mean the  Corporation as hereinbefore defined  and any successor or
assignee to the business or assets which by reason hereof becomes bound by  this
Plan.

                                  ARTICLE VII
                      DURATION, AMENDMENT AND TERMINATION

    7.1   DURATION.  If the Combination has not occurred, this Plan shall expire
five years from the Effective Date, unless extended for an additional period  or
periods by resolution adopted by the Board.

    If the Combination occurs, this Plan shall continue in full force and effect
and  shall  not terminate  or  expire until  after  all Participants  who become
entitled to any payments hereunder shall have received such payments in full and
all adjustments required to be made pursuant to Section 4.5 have been made.

                                      A-63
<PAGE>
    7.2  AMENDMENT.  Except  as provided in Section 7.1,  the Plan shall not  be
subject  to amendment, change, substitution, deletion, revocation or termination
in any respect which adversely affects the rights of Participants.

    7.3  FORM OF AMENDMENT.   The form of any amendment  of the Plan shall be  a
written  instrument  signed by  a  duly authorized  officer  or officers  of the
Corporation, certifying that the amendment has been approved by the Board.

                                  ARTICLE VIII
                                 MISCELLANEOUS

    8.1   INDEMNIFICATION.   If a  Participant institutes  any legal  action  in
seeking  to obtain or enforce, or is required  to defend in any legal action the
validity or enforceability of, any right  or benefit provided by this Plan,  the
Corporation  or the  Employer will  pay for all  actual legal  fees and expenses
incurred (as incurred) by  such Participant, regardless of  the outcome of  such
action.

    8.2    EMPLOYMENT STATUS.    This Plan  does  not constitute  a  contract of
employment or  impose  on the  Participant  or the  Participant's  Employer  any
obligation to retain the Participant as an Employee, to change the status of the
Participant's  employment, or to  change the Corporation's  policies or those of
its Subsidiaries regarding termination of employment.

    8.3  CLAIM PROCEDURE.   If an  Employee or former  Employee makes a  written
request alleging a right to receive benefits under this Plan or alleging a right
to  receive an adjustment in benefits being paid under the Plan, the Corporation
shall treat it as  a claim for  benefit. All claims for  benefit under the  Plan
shall  be sent to the Human Resources  Department of the Corporation and must be
received within  30 days  after termination  of employment.  If the  Corporation
determines  that any individual who has claimed  a right to receive benefits, or
different benefits, under the Plan is not entitled to receive all or any part of
the  benefits  claimed,  it  will  inform   the  claimant  in  writing  of   its
determination  and the reasons therefor in  terms calculated to be understood by
the claimant. The notice  will be sent  within 90 days of  the claim unless  the
Corporation  determines additional time,  not exceeding 90  days, is needed. The
notice shall make specific reference to  the pertinent Plan provisions on  which
the denial is based, and describe any additional material or information that is
necessary.  Such notice shall,  in addition, inform  the claimant what procedure
the claimant should follow to take advantage of the review procedures set  forth
below  in the event the claimant desires to contest the denial of the claim. The
claimant may within 90  days thereafter submit in  writing to the Corporation  a
notice  that  the  claimant contests  the  denial of  his  or her  claim  by the
Corporation and desires a further review.  The Corporation shall within 60  days
thereafter  review the claim and authorize the claimant to appear personally and
review pertinent documents and submit issues and comments relating to the  claim
to  the  persons  responsible for  making  the  determination on  behalf  of the
Corporation. The  Corporation  will  render its  final  decision  with  specific
reasons  therefor in writing and will transmit it to the claimant within 60 days
of the written request for review, unless the Corporation determines  additional
time,  not exceeding 60 days, is needed, and so notifies the Participant. If the
Corporation fails to respond to a  claim filed in accordance with the  foregoing
within  60 days or any such extended  period, the Corporation shall be deemed to
have denied the claim.

    8.4  VALIDITY AND SEVERABILITY.   The invalidity or unenforceability of  any
provision  of the Plan  shall not affect  the validity or  enforceability of any
other provision of the Plan,  which shall remain in  full force and effect,  and
any  prohibition or unenforceability in any jurisdiction shall not invalidate or
render unenforceable such provision in any other jurisdiction.

    8.5    GOVERNING  LAW.    The  validity,  interpretation,  construction  and
performance  of  the Plan  shall  in all  respects be  governed  by the  laws of
Minnesota, without reference  to principles of  conflict of law,  except to  the
extent pre-empted by federal law.

                                             EXHIBIT 7.10(b) TO MERGER AGREEMENT

                                      WEC
                       SENIOR EXECUTIVE SEVERANCE POLICY
                                  INTRODUCTION

    Northern States Power Company, a Minnesota corporation ("NSP") and Wisconsin
Energy  Corporation,  a  Wisconsin  corporation  ("WEC")  have  entered  into an
Agreement  and  Plan  of  Merger  dated  as  of  April  28,  1995  (the  "Merger
Agreement"),  whereby the NSP and  WEC organizations will merge  with WEC as the
surviving parent (the "Combination"). The  Board of Directors of WEC  recognizes
that  the pendency of the Combination,  and the inevitable adjustments that will
occur during the transition period following the Combination, may result in  the
loss or distraction of employees of WEC and its Subsidiaries to the detriment of
WEC and its shareholders.

    The  Board  considers  the avoidance  of  such  loss and  distraction  to be
essential to  protecting  and  enhancing  the best  interests  of  WEC  and  its
shareholders.   The  Board  also  believes  that  during  the  pendency  of  the
Combination and the transition  period thereafter, the Board  should be able  to
receive  and rely on  disinterested service from  employees without concern that
employees might be distracted or concerned by personal uncertainties and risks.

    In addition, the Board believes that it is consistent with WEC's  employment
practices  and policies and in the best interests of WEC and its shareholders to
treat fairly its  employees whose  employment terminates in  connection with  or
following the Combination.

    Accordingly, the Board has determined that appropriate steps should be taken
to  assure WEC of the continued employment  and attention and dedication to duty
of its  employees and  to seek  to ensure  the availability  of their  continued
service, notwithstanding the Combination.

    Therefore,  in order to  fulfill the above purposes,  the following plan has
been developed and is hereby adopted.

                                   ARTICLE I

maintained  by  the  Corporation  or  deferred pursuant  to  a  written  plan or

is  entitled to payment of a Separation Benefit as provided in the Plan or there
has been an event or occurrence  described in Section 4.2(a) which would  enable
the  Participant to terminate his employment and receive a Separation Benefit. A
Participant entitled to  payment of a  Separation Benefit or  any other  amounts
under  the Plan shall remain a Participant in  the Plan until the full amount of
the Separation Benefit and  any other amounts payable  under the Plan have  been

                                   ARTICLE IV
                              SEPARATION BENEFITS

    4.1    RIGHT TO  SEPARATION BENEFIT.    A Participant  shall be  entitled to
receive Separation Benefits in  accordance with Section  4.3 if the  Participant
ceases to be an Employee for any reason specified in Section 4.2(a).

    4.2  TERMINATION OF EMPLOYMENT.

    (a)    TERMINATIONS  WHICH  GIVE  RISE  TO  SEPARATION  BENEFITS  UNDER THIS
PLAN.  Except  as set  forth in  subsection (b)  below, a  Participant shall  be
entitled  to Separation Benefits if at any time before the second anniversary of
the Date of the Combination:

        (i) the Participant ceases to be  an Employee by action of the  Employer
    or any of its affiliates (excluding any transfer to another Employer);

        (ii)  the Participant's Annual Salary is reduced below the higher of (x)
    the amount in effect  on the Effective  Date and (y)  the highest amount  in
    effect  at any time thereafter, and the Participant ceases to be an Employee
    by his  or her  own  action within  90 days  after  the occurrence  of  such
    reduction;

       (iii)  the Participant's  duties and  responsibilities or  the program of
    incentive compensation and  retirement and welfare  benefits offered to  the
    Participant  are materially  and adversely  diminished in  comparison to the
    duties and  responsibilities  or the  program  of benefits  enjoyed  by  the
    Participant  on  the Effective  Date, and  the Participant  ceases to  be an
    Employee by his or her own action within 90 days after the occurrence  after
    such reduction;

       (iv)  the Participant is required to be  based at a location more than 50
    miles from  the  location where  the  Participant was  based  and  performed
    services on the Effective Date, and the Participant ceases to be an Employee
    by his or her own action within 90 days after such relocation;

        (v)  an  Employer or  any affiliate  of an  Employer sells  or otherwise
    distributes or disposes of the subsidiary, branch or other business unit  in
    which  the  Participant  was  employed  before  such  sale,  distribution or
    disposition and the requirements of  subsection (b)(iv) of this Section  4.2
    are  not met, and the Participant ceases to be an Employee upon or within 90
    days after such sale, distribution or disposition.

    (b)  TERMINATIONS WHICH DO NOT  GIVE RISE TO SEPARATION BENEFITS UNDER  THIS
PLAN.    If  a Participant's  employment  is terminated  for  Cause, disability,
retirement, or a qualified sale of business (as those terms are defined  below),
or  voluntarily  by the  Participant in  the  absence of  an event  described in
subsection (a)(ii), (iii) or (iv) of this Section 4.2, the Participant shall not
be entitled to Separation Benefits under the Plan.

        (i) A termination for disability shall have occurred where a Participant
    is terminated because illness  or injury has  prevented him from  performing
    his duties (as they existed immediately prior to the illness or injury) on a
    full time basis for 180 consecutive business days.

        (ii)   A  termination  by   retirement  shall  have   occurred  where  a
    Participant's termination  is due  to his  voluntary late,  normal or  early
    retirement under a pension plan sponsored by his Employer or its affiliates,
    as defined in such plan.

       (iii)  A termination for Cause shall have occurred where a Participant is
    terminated because of:

           (A) the willful and continued  failure of the Participant to  perform
       substantially the Participant's duties with the Corporation or one of its
       affiliates  (other than any such failure resulting from incapacity due to
       physical or  mental  illness), after  a  written demand  for  substantial
       performance  is delivered to  the Participant by the  Board or an elected
       officer of

                                      A-67
<PAGE>
       the Corporation which  specifically identifies  the manner  in which  the
       Board  or  the  elected officer  believes  that the  Participant  has not
       substantially performed the Participant's duties, or

           (B) the willful  engaging by  the Participant in  illegal conduct  or
       gross  misconduct which is  materially and demonstrably  injurious to the
       Corporation.

    For purposes of this provision, no act or failure to act, on the part of the
    Participant, shall be considered "willful" unless it is done, or omitted  to
    be  done, by the Participant in bad  faith or without reasonable belief that
    the Participant's  action or  omission  was in  the  best interests  of  the
    Corporation. Any act, or failure to act, based upon authority given pursuant
    to  a resolution duly adopted by the Board or upon the advice of counsel for
    the Corporation, shall be conclusively presumed to be done, or omitted to be
    done, by the  Participant in good  faith and  in the best  interests of  the
    Corporation.

       (iv)  A  termination  due to  a  qualified  sale of  business  shall have
    occurred where  an  Employer  or  an affiliate  of  an  Employer  has  sold,
    distributed  or  otherwise  disposed  of  the  subsidiary,  branch  or other
    business unit  in  which the  Participant  was employed  before  such  sale,
    distribution  or disposition and the Participant has been offered employment
    with the purchaser of such subsidiary, branch or other business unit or  the
    corporation  or other entity which is the owner thereof on substantially the
    same terms and conditions under which he worked for the Employer (including,
    without limitation,  base salary,  duties and  responsibilities, program  of
    benefits  and location  where based). Such  terms and  conditions shall also
    include, without limitation,  a legally binding  agreement or plan  covering
    such  Participant, providing that upon a  termination of employment with the
    subsidiary, branch  or business  unit (or  the corporation  or other  entity
    which  is the owner thereof) or any  successor thereto of the kind described
    in Article VI of this Plan, at any time before the second anniversary of the
    Date of the Combination,  the Participant's employer  or any successor  will
    pay  to  each such  former  Participant an  amount  equal to  the separation
    benefit and other benefits that such former Participant would have  received
    under  the Plan had he  been a Participant at  the time of such termination.
    For purposes of  this subsection, the  new employer plan  or agreement  must
    treat service with any Employer (irrespective of whether the Employer was an
    affiliate  of the Corporation or the Employee  was a Participant at the time
    of such service) and the new employer as continuous service for purposes  of
    calculating separation benefits.

    4.3  SEPARATION BENEFITS.

    (a)  If a Participant's employment  is terminated in circumstances entitling
him to a  separation benefit as  provided in Section  4.2(a), the  Participant's
Employer shall pay such Participant, within ten days of the Date of Termination,
a  cash lump sum as set forth in subsection (b) below and the continued benefits
set forth in subsection (c) below. For purposes of determining the benefits  set
forth  in  subsections (b)  and  (c), if  the  termination of  the Participant's
employment is  based upon  a reduction  of the  Participant's Annual  Salary  or
benefits as described in subsection (ii) or (iii) of Section 4.2, such reduction
shall be ignored.

    (b)  The  cash  lump sum  referred  to  in Section  4.3(a)  shall  equal the
aggregate of the following amounts:

        (i) the sum of (1) the  Participant's Annual Salary through the Date  of
    Termination  to the extent not theretofore paid,  (2) the product of (x) the
    Target Incentive and (y) a fraction, the numerator of which is the number of
    days in such year  through the Date of  Termination, and the denominator  of
    which   is  365,  and  (3)  any  compensation  previously  deferred  by  the
    Participant (together with any accrued interest or earnings thereon) and any
    accrued vacation pay, in each case to the extent not theretofore paid and in
    full satisfaction of the rights of the Participant thereto;

                                      A-68
<PAGE>
        (ii) an amount equal to the product of (1) three, and (2) the sum of (x)
    the Participant's Annual  Salary and  (y) the  higher of  the Target  Annual
    Incentive or the Annual Incentive Award; and

       (iii)  an  amount  equal  to the  difference  between  (a)  the actuarial
    equivalent of the benefit under the Corporation's qualified defined  benefit
    retirement  plan  (the "Retirement  Plan")  and any  excess  or supplemental
    retirement plans  in  which  the  Participant  participates  (together,  the
    "SERP")  which  the  Participant  would receive  if  his  or  her employment
    continued during  the Separation  Period,  assuming that  the  Participant's
    compensation  during the Separation  Period would have been  equal to his or
    her compensation  as in  effect immediately  before the  termination or,  if
    higher,  on  the Effective  Date, and  (b) the  actuarial equivalent  of the
    Participant's actual benefit (paid or payable), if any, under the Retirement
    Plan and the SERP as of  the Date of Termination. The actuarial  assumptions
    used  for purposes  of determining  actuarial equivalence  shall be  no less
    favorable to the  Participant than  the most  favorable of  those in  effect
    under  the Retirement Plan and  the SERP on the  Date of Termination and the
    Effective Date.

    (c) The continued benefits referred to above shall be as follows:

        (i) During the Separation Period,  the Participant and his family  shall
    be  provided  with medical,  dental and  life insurance  benefits as  if the
    Participant's employment had not been terminated; provided, however, that if
    the Participant becomes reemployed with another employer and is eligible  to
    receive  medical or  other welfare benefits  under another employer-provided
    plan, the  medical and  other  welfare benefits  described herein  shall  be
    secondary  to those  provided under such  other plan  during such applicable
    period of eligibility. For purposes of determining eligibility (but not  the
    time  of commencement of  benefits) of the  Participant for retiree medical,
    dental and life insurance benefits under the Corporation's plans, practices,
    programs and policies, the Participant shall be considered to have  remained
    employed during the Separation Period and to have retired on the last day of
    such period;

        (ii) The Corporation shall, at its sole expense as incurred, provide the
    Participant with outplacement services the scope and provider of which shall
    be  selected by the Participant in his or her sole discretion (but at a cost
    to the  Corporation of  not  more than  $30,000)  or, at  the  Participant's
    option,  the  use  of  office  space,  office  supplies  and  equipment  and
    secretarial services for a period not to exceed one year;

       (iii) The  Corporation shall  continue to  provide the  Participant  with
    financial planning counseling benefits through the second anniversary of the
    Date  of Termination,  on the  same terms and  conditions as  were in effect
    immediately before the termination or,  if more favorable, on the  Effective
    Date; and

       (iv) The Corporation shall transfer to the Participant, at no cost to the
    Participant,  the title to the company car  being used by the Participant as
    of the Date of Termination.

To the extent any benefits described  in this Section 4.3(c) cannot be  provided
pursuant  to  the  appropriate plan  or  program maintained  for  Employees, the
Employer shall  provide  such  benefits  outside such  plan  or  program  at  no
additional cost (including without limitation tax cost) to the Participant.

    4.4   OTHER  BENEFITS PAYABLE.   The cash  lump sum  and continuing benefits
described in Section 4.3 above shall be payable in addition to, and not in  lieu
of,  all other  accrued or vested  or earned but  deferred compensation, rights,
options or other benefits which may be  owed to a Participant upon or  following
termination,  including but not limited to accrued vacation or sick pay, amounts
or benefits payable under  any bonus or other  compensation plans, stock  option
plan,  stock ownership  plan, stock purchase  plan, life  insurance plan, health
plan, disability plan or similar or  successor plan but excluding any  severance
pay  or pay  in lieu  of notice required  to be  paid to  such Participant under
applicable law.

    4.5  CERTAIN REDUCTION OF PAYMENTS BY THE CORPORATION.

    (a)  For purposes of this Section 4.5,  (i) a Payment shall mean any payment
or distribution  in the  nature  of compensation  to or  for  the benefit  of  a
Participant,  whether paid or  payable pursuant to this  Plan or otherwise; (ii)
Separation Payment shall mean  a Payment paid or  payable pursuant to this  Plan
(disregarding  this Section); (iii) Net After Tax Receipt shall mean the Present
Value of  a Payment  net of  all taxes  imposed on  a Participant  with  respect
thereto  under Sections  1 and  4999 of  the Internal  Revenue Code  of 1986, as
amended (the "Code"),  determined by  applying the highest  marginal rate  under
Section  1 of the Code which applied to the Participant's taxable income for the
immediately preceding taxable year; (iv)  "Present Value" shall mean such  value
determined  in accordance with Section 280G(d)(4)  of the Code; and (v) "Reduced
Amount" shall mean the  greatest aggregate amount  of Separation Payments  which
(a) is less than the sum of all Separation Payments and (b) results in aggregate
Net  After Tax  Receipts which are  equal to or  greater than the  Net After Tax
Receipts which  would  result  if the  Participant  were  paid the  sum  of  all
Separation Payments.

    (b) Anything in this Agreement to the contrary notwithstanding, in the event
Price  Waterhouse or such  other certified public  accounting firm designated by
the Participant  (the "Accounting  Firm") shall  determine that  receipt of  all
Payments would subject the Participant to tax under Section 4999 of the Code, it
shall  determine  whether  some amount  of  Separation Payments  would  meet the
definition of a "Reduced Amount." If  the Accounting Firm determines that  there
is  a Reduced Amount, the aggregate Separation Payments shall be reduced to such
Reduced Amount. All fees payable to the Accounting Firm shall be paid solely  by
the Corporation.

    (c)  If the  Accounting Firm  determines that  aggregate Separation Payments
should be reduced to the Reduced Amount, the Corporation shall promptly give the
Participant notice  to  that effect  and  a  copy of  the  detailed  calculation
thereof,  and the Participant may then elect,  in his sole discretion, which and
how much of the Separation Payments shall  be eliminated or reduced (as long  as
after  such  election the  present value  of  the aggregate  Separation Payments
equals the Reduced Amount), and shall  advise the Corporation in writing of  his
election  within ten days of his receipt of  notice. If no such election is made
by the Participant within such ten-day  period, the Corporation may elect  which
of  such Separation Payments  shall be eliminated  or reduced (as  long as after
such election the present value of the aggregate Separation Payments equals  the
Reduced  Amount) and shall notify the Participant promptly of such election. All
determinations made by the Accounting Firm  under this Section shall be  binding
upon  the Corporation and the Participant and shall  be made within 60 days of a
termination of  employment  of  the  Participant.  As  promptly  as  practicable
following such determination, the Corporation shall pay to or distribute for the
benefit  of the  Participant such  Separation Payments  as are  then due  to the
Participant under this  Plan and  shall promptly pay  to or  distribute for  the
benefit  of the Participant in the future such Separation Payments as become due
to the Participant under this Plan.

    (d) While  it is  the intention  of the  Corporation to  reduce the  amounts
payable or distributable to the Participants hereunder only if the aggregate Net
After  Tax Receipts to a Participant would  thereby be increased, as a result of
the uncertainty in the application  of Section 4999 of the  Code at the time  of
the  initial determination by the Accounting Firm hereunder, it is possible that
amounts will have  been paid or  distributed by  the Corporation to  or for  the
benefit  of a Participant  pursuant to this  Plan which should  not have been so
paid or distributed ("Overpayment") or  that additional amounts which will  have
not  been paid  or distributed  by the Corporation  to or  for the  benefit of a
Participant pursuant  to  this Plan  could  have  been so  paid  or  distributed
("Underpayment"),  in each case, consistent with  the calculation of the Reduced
Amount hereunder.  In  the event  that  the  Accounting Firm,  either  upon  the
assertion  of a  deficiency by the  Internal Revenue Service  against either the
Corporation or the  Participant which the  Accounting Firm believes  has a  high
probability  of success determines  that an Overpayment has  been made, any such
Overpayment paid or distributed by  the Corporation to or  for the benefit of  a
Participant shall be treated for all purposes as a loan to the Participant which
the  Participant shall  repay to the  Corporation together with  interest at the
applicable federal  rate  provided  for  in  Section  7872(f)(2)  of  the  Code;
provided, however, that no such loan

                                      A-70
<PAGE>
shall  be  deemed  to  have been  made  and  no  amount shall  be  payable  by a
Participant to the Corporation if and to the extent such deemed loan and payment
would not either reduce the  amount on which the  Participant is subject to  tax
under Section 1 and Section 4999 of the Code or generate a refund of such taxes.
In  the  event that  the Accounting  Firm, based  upon controlling  precedent or
substantial authority, determines  that an Underpayment  has occurred, any  such
Underpayment  shall be promptly paid by the Corporation to or for the benefit of
the Participant together with interest  at the applicable federal rate  provided
for in Section 7872(f)(2) of the Code.

    4.6   PAYMENT OBLIGATIONS ABSOLUTE.  Subject to Section 4.5, the obligations
of the Corporation and the Employers to pay the separation benefits described in
Section 4.3 shall be absolute and unconditional and shall not be affected by any
circumstances,  including,  without   limitation,  any  set-off,   counterclaim,
recoupment,  defense  or  other  right  which  the  Corporation  or  any  of its
Subsidiaries may have against any Participant.  In no event shall a  Participant
be  obligated  to seek  other  employment or  take any  other  action by  way of
mitigation of the amounts payable to  a Participant under any of the  provisions
of  this Plan, nor shall  the amount of any payment  hereunder be reduced by any
compensation earned  by a  Participant  as a  result  of employment  by  another
employer, except as specifically provided in Section 4.3(c)(i).

                                   ARTICLE V
                            PARTICIPATING EMPLOYERS

    This  Plan may be  adopted by any  Subsidiary of the  Corporation. Upon such
adoption, the Subsidiary shall become  an Employer hereunder and the  provisions
of  the Plan shall be  fully applicable to the  Employees of that Subsidiary who
are Participants pursuant to Section 3.1.

                                   ARTICLE VI
                            SUCCESSOR TO CORPORATION

    This Plan shall  bind any successor  of the Corporation,  its assets or  its
businesses  (whether direct or  indirect, by purchase,  merger, consolidation or
otherwise) in the same manner and to the same extent that the Corporation  would
be obligated under this Plan if no succession had taken place.

    In  the  case of  any  transaction in  which a  successor  would not  by the
foregoing provision  or  by  operation  of  law  be  bound  by  this  Plan,  the
Corporation shall require such successor expressly and unconditionally to assume
and  agree to perform the Corporation's obligations under this Plan, in the same
manner and to the same extent that the Corporation would be required to  perform
if  no such succession had taken place.  The term "Corporation," as used in this
Plan, shall mean the  Corporation as hereinbefore defined  and any successor  or
assignee  to the business or assets which by reason hereof becomes bound by this
Plan.

                                  ARTICLE VII
                      DURATION, AMENDMENT AND TERMINATION

    7.1  DURATION.  If the Combination has not occurred, this Plan shall  expire
five  years from the Effective Date, unless extended for an additional period or
periods by resolution adopted by the Board.

    If the Combination occurs, this Plan shall continue in full force and effect
and shall  not terminate  or  expire until  after  all Participants  who  become
entitled to any payments hereunder shall have received such payments in full and
all adjustments required to be made pursuant to Section 4.5 have been made.

    7.2   AMENDMENT.  Except  as provided in Section 7.1,  the Plan shall not be
subject to amendment, change, substitution, deletion, revocation or  termination
in any respect which adversely affects the rights of Participants.

                                      A-71
<PAGE>
    7.3   FORM OF AMENDMENT.   The form of any amendment  of the Plan shall be a
written instrument  signed by  a  duly authorized  officer  or officers  of  the
Corporation, certifying that the amendment has been approved by the Board.

                                  ARTICLE VIII
                                 MISCELLANEOUS

    8.1    INDEMNIFICATION.   If a  Participant institutes  any legal  action in
seeking to obtain or enforce, or is  required to defend in any legal action  the
validity  or enforceability of, any right or  benefit provided by this Plan, the
Corporation or the  Employer will  pay for all  actual legal  fees and  expenses
incurred  (as incurred) by  such Participant, regardless of  the outcome of such
action.

    8.2   EMPLOYMENT  STATUS.   This  Plan does  not  constitute a  contract  of
employment  or  impose  on the  Participant  or the  Participant's  Employer any
obligation to retain the Participant as an Employee, to change the status of the
Participant's employment, or to  change the Corporation's  policies or those  of
its Subsidiaries regarding termination of employment.

    8.3   CLAIM PROCEDURE.   If an  Employee or former  Employee makes a written
request alleging a right to receive benefits under this Plan or alleging a right
to receive an adjustment in benefits being paid under the Plan, the  Corporation
shall  treat it as  a claim for benefit.  All claims for  benefit under the Plan
shall be sent to the Human Resources  Department of the Corporation and must  be
received  within 30  days after  termination of  employment. If  the Corporation
determines that any individual who has  claimed a right to receive benefits,  or
different benefits, under the Plan is not entitled to receive all or any part of
the   benefits  claimed,  it  will  inform   the  claimant  in  writing  of  its
determination and the reasons therefor in  terms calculated to be understood  by
the  claimant. The notice  will be sent within  90 days of  the claim unless the
Corporation determines additional time,  not exceeding 90  days, is needed.  The
notice  shall make specific reference to  the pertinent Plan provisions on which
the denial is based, and describe any additional material or information that is
necessary. Such notice shall,  in addition, inform  the claimant what  procedure
the  claimant should follow to take advantage of the review procedures set forth
below in the event the claimant desires to contest the denial of the claim.  The
claimant  may within 90 days  thereafter submit in writing  to the Corporation a
notice that  the  claimant contests  the  denial of  his  or her  claim  by  the
Corporation  and desires a further review.  The Corporation shall within 60 days
thereafter review the claim and authorize the claimant to appear personally  and
review  pertinent documents and submit issues and comments relating to the claim
to the  persons  responsible for  making  the  determination on  behalf  of  the
Corporation.  The  Corporation  will  render its  final  decision  with specific
reasons therefor in writing and will transmit it to the claimant within 60  days
of  the written request for review, unless the Corporation determines additional
time, not exceeding 60 days, is needed, and so notifies the Participant. If  the
Corporation  fails to respond to a claim  filed in accordance with the foregoing
within 60 days or any such extended  period, the Corporation shall be deemed  to
have denied the claim.

    8.4   VALIDITY AND SEVERABILITY.   The invalidity or unenforceability of any
provision of the  Plan shall not  affect the validity  or enforceability of  any
other  provision of the Plan,  which shall remain in  full force and effect, and
any prohibition or unenforceability in any jurisdiction shall not invalidate  or
render unenforceable such provision in any other jurisdiction.

    8.5    GOVERNING  LAW.    The  validity,  interpretation,  construction  and
performance of  the Plan  shall  in all  respects be  governed  by the  laws  of
Wisconsin,  without reference  to principles of  conflict of law,  except to the
extent pre-empted by federal law.

                           NSP STOCK OPTION AGREEMENT

    STOCK  OPTION AGREEMENT, dated as  of April 28, 1995  by and among Wisconsin
Energy Corporation, a Wisconsin corporation  ("WEC"), and Northern States  Power
Company, a Minnesota corporation (the "COMPANY").

    WHEREAS, concurrently with the execution and delivery of this Agreement, (i)
the  Company, WEC, Northern Power Wisconsin Corp., a Wisconsin corporation ("NEW
NSP") and WEC Sub Corp., a  Wisconsin corporation ("SUB"), are entering into  an
Agreement  and  Plan  of  Merger,  dated as  of  the  date  hereof  (the "MERGER
AGREEMENT"), which provides, among other things,  upon the terms and subject  to
the  conditions thereof, for the merger of the Company with and into New NSP and
the merger of Sub with  and into New NSP (the  "MERGERS"), and (ii) WEC and  the
Company  are entering into a certain stock option agreement dated as of the date
hereof whereby  WEC grants  to the  Company an  option with  respect to  certain
shares  of WEC's  common stock on  the terms  and subject to  the conditions set
forth therein (the "WEC STOCK OPTION AGREEMENT"); and

    WHEREAS, as  a condition  to  WEC's willingness  to  enter into  the  Merger
Agreement,  WEC has  requested that  the Company agree,  and the  Company has so
agreed, to  grant  to WEC  an  option with  respect  to certain  shares  of  the
Company's  common stock, on  the terms and  subject to the  conditions set forth
herein.

    NOW, THEREFORE, to  induce WEC to  enter into the  Merger Agreement, and  in
consideration of the mutual covenants and agreements set forth herein and in the
Merger Agreement, the parties hereto agree as follows:

        1.   GRANT  OF OPTION.   The  Company hereby  grants WEC  an irrevocable
    option (the "COMPANY OPTION") to  purchase up to 13,387,772 shares,  subject
    to  adjustment  as provided  in SECTION  11 (such  shares being  referred to
    herein as the "COMPANY SHARES") of common stock, par value $2.50 per  share,
    of  the Company (the "COMPANY  COMMON STOCK") (being 19.9%  of the number of
    shares of Company Common Stock outstanding on the date hereof) in the manner
    set forth  below at  a price  (the "EXERCISE  PRICE") per  Company Share  of
    $44.075  (which is equal  to the Fair  Market Value (as  defined below) of a
    Company Share on the date hereof) payable,  at WEC's option, (a) in cash  or
    (b)   subject  to  the  Company's  having  obtained  the  approvals  of  any
    Governmental Authority required for  the Company to  acquire the WEC  Shares
    (as  defined below)  from WEC,  which approvals  the Company  shall use best
    efforts to obtain, in shares of common  stock, par value $.01 per share,  of
    WEC  ("WEC  SHARES") in  either case  in accordance  with Section  4 hereof.
    Notwithstanding the  foregoing, in  no  event shall  the number  of  Company
    Shares  for  which the  Company Option  is exercisable  exceed 19.9%  of the
    number of issued  and outstanding shares  of Company Common  Stock. As  used
    herein,  the "FAIR MARKET  VALUE" of any  share shall be  the average of the
    daily closing sales price for such share on the New York Stock Exchange (the
    "NYSE") during the 10 NYSE trading days prior to the fifth NYSE trading  day
    preceding  the date such Fair Market  Value is to be determined. Capitalized
    terms used herein but not defined  herein shall have the meanings set  forth
    in the Merger Agreement.

        2.   EXERCISE OF OPTION.  The Company Option may be exercised by WEC, in
    whole or  in part,  at  any time  or  from time  to  time after  the  Merger
    Agreement  becomes terminable by WEC under circumstances which could entitle
    WEC to termination fees under either Section 9.3(a) of the Merger  Agreement
    (provided  that the events specified in  Section 9.3(a)(ii)(x) of the Merger
    Agreement shall  have occurred,  although the  events specified  in  Section
    9.3(a)(ii)(y)  thereof  need not  have occurred)  or  Section 9.3(b)  of the
    Merger Agreement (regardless  of whether  the Merger  Agreement is  actually
    terminated  or whether  there occurs a  closing of  any Business Combination
    involving a Target  Party or a  closing by  which a Target  Party becomes  a
    subsidiary),  any  such  event  by which  the  Merger  Agreement  becomes so
    terminable by WEC being referred to herein as a "TRIGGER EVENT." The Company
    shall  notify   WEC  promptly   in  writing   of  the   occurrence  of   any

                                      B-1
<PAGE>
    Trigger  Event, it being  understood that the  giving of such  notice by the
    Company shall not be a condition to the right of WEC to exercise the Company
    Option. In the event  WEC wishes to exercise  the Company Option, WEC  shall
    deliver  to the Company  a written notice  (an "EXERCISE NOTICE") specifying
    the total number of Company Shares it wishes to purchase. Each closing of  a
    purchase  of Company Shares (a "CLOSING") shall  occur at a place, on a date
    and at a time designated by WEC in an Exercise Notice delivered at least two
    business days prior  to the date  of the Closing.  The Company Option  shall
    terminate  upon the earlier of: (i) the Effective Time; (ii) the termination
    of the Merger Agreement pursuant to Section 9.1 thereof (other than upon  or
    during  the continuance of a Trigger Event); or (iii) 180 days following any
    termination of the  Merger Agreement  upon or  during the  continuance of  a
    Trigger  Event (or if, at the expiration  of such 180 day period the Company
    Option cannot be  exercised by  reason of any  applicable judgment,  decree,
    order, law or regulation, 10 business days after such impediment to exercise
    shall  have  been removed  or shall  have  become final  and not  subject to
    appeal, but  in no  event under  this clause  (iii) later  than October  31,
    1997).  Notwithstanding  the  foregoing,  the  Company  Option  may  not  be
    exercised  if  WEC   is  in  material   breach  of  any   of  its   material
    representations or warranties, or in material breach of any of its covenants
    or  agreements, contained in this Agreement or in the Merger Agreement. Upon
    the giving by WEC to  the Company of the Exercise  Notice and the tender  of
    the  applicable  aggregate Exercise  Price, WEC  shall be  deemed to  be the
    holder of  record  of  the  Company  Shares  issuable  upon  such  exercise,
    notwithstanding  that the stock transfer books  of the Company shall then be
    closed or that certificates representing such Company Shares shall not  then
    be actually delivered to WEC.

        3.   CONDITIONS TO CLOSING.  The  obligation of the Company to issue the
    Company Shares to WEC hereunder is  subject to the conditions, which  (other
    than  the conditions described in clauses (i),  (iii) and (iv) below) may be
    waived by the Company in its sole discretion, that (i) all waiting  periods,
    if  any, under the HSR Act, applicable to the issuance of the Company Shares
    hereunder shall  have expired  or  have been  terminated; (ii)  the  Company
    Shares,  and any  WEC Shares  which are  issued in  payment of  the Exercise
    Price, shall have been approved for listing on the NYSE upon official notice
    of issuance; (iii) all consents, approvals, orders or authorizations of,  or
    registrations,  declarations or  filings with,  any federal,  state or local
    administrative  agency  or  commission  or  other  federal  state  or  local
    Governmental  Authority, if any, required in connection with the issuance of
    the Company Shares hereunder shall have  been obtained or made, as the  case
    may be, including, without limitation, the approval of the SEC under Section
    10  of the 1935 Act of the acquisition  of the Company Shares by WEC and, if
    applicable, the acquisition by  the Company of  the WEC Shares  constituting
    the   Exercise  Price  hereunder;  and  (iv)  no  preliminary  or  permanent
    injunction or other order by any court of competent jurisdiction prohibiting
    or otherwise restraining such issuance shall be in effect.

        4.  CLOSING.  At any Closing, (a) the Company will deliver to WEC or its
    designee a single certificate in definitive form representing the number  of
    the   Company  Shares  designated  by  WEC  in  its  Exercise  Notice,  such
    certificate to be registered in the name  of WEC and to bear the legend  set
    forth  in SECTION 12, and (b) WEC  will deliver to the Company the aggregate
    price for the Company Shares so  designated and being purchased by (i)  wire
    transfer  of immediately available funds or certified check or bank check or
    (ii) subject to the condition in Section 1(b), a certificate or certificates
    representing the number of WEC Shares  being issued by WEC in  consideration
    thereof,  as the case may be. For the purposes of this Agreement, the number
    of WEC Shares to be delivered to the Company shall be equal to the  quotient
    obtained  by dividing (i)  the product of  (x) the number  of Company Shares
    with respect to  which the  Company Option is  being exercised  and (y)  the
    Exercise  Price by (ii) the Fair Market Value  of the WEC Shares on the date
    immediately preceding  the date  the  Exercise Notice  is delivered  to  the
    Company.  The Company shall pay all expenses,  and any and all United States
    federal, state and  local taxes  and other charges  that may  be payable  in
    connection  with the preparation,  issue and delivery  of stock certificates
    under this Section 4 in the name of WEC or its designee.

        7.  CERTAIN REPURCHASES.

        (a)   WEC  PUT.  At  the request  of WEC by  written notice  at any time
    during which the Company  Option is exercisable pursuant  to SECTION 2  (the
    "REPURCHASE  PERIOD"), the Company  (or any successor  entity thereof) shall
    repurchase from WEC all or any portion  of the Company Option, at the  price
    set  forth in subparagraph (i)  below, or, at the  request of WEC by written
    notice at any time prior to April 30, 1997 (provided that such date shall be
    extended to October 31,  1997 under the circumstances  where the date  after
    which  either party may  terminate the Merger  Agreement pursuant to Section
    9.1(b)  of  the  Merger   Agreement  has  been   extended  to  October   31,

                                      B-4
<PAGE>
    1997),  the Company (or any successor  entity thereof) shall repurchase from
    WEC all or any portion  of the Company Shares  purchased by WEC pursuant  to
    the Company Option, at the price set forth in subparagraph (ii) below:

           (i)  the difference  between the  "MARKET/OFFER PRICE"  for shares of
       Company Common Stock as  of the date  WEC gives notice  of its intent  to
       exercise  its rights under this  SECTION 7 (defined as  the higher of (A)
       the price per share  offered as of  such date pursuant  to any tender  or
       exchange  offer or  other offer  with respect  to a  Business Combination
       which was made prior to such date  and not terminated or withdrawn as  of
       such  date (the "OFFER PRICE")  and (B) the Fair  Market Value of Company
       Common Stock  as of  such date  (the "MARKET  PRICE")) and  the  Exercise
       Price, multiplied by the number of Company Shares purchasable pursuant to
       the  Company  Option (or  portion thereof  with respect  to which  WEC is
       exercising its rights under this SECTION 7), but only if the Market/Offer
       Price is greater than the Exercise Price;

           (ii) the product of (x) the sum of (A) the Exercise Price paid by WEC
       per Company Share  acquired pursuant to  the Company Option  and (B)  the
       difference  between the  Market/Offer Price  and the  Exercise Price, but
       only if the Market/Offer  Price is greater than  the Exercise Price,  and
       (y)  the number of Company  Shares so to be  repurchased pursuant to this
       SECTION 7. For purposes of this clause (ii), the Offer Price shall be the
       highest price per share offered pursuant to a tender or exchange offer or
       other Business Combination  offer during the  Repurchase Period prior  to
       the delivery by WEC of a notice of repurchase.

        (b)   REDELIVERY  OF WEC  SHARES.   If WEC  elected to  purchase Company
    Shares pursuant to the  exercise of the Company  Option by the issuance  and
    delivery  of WEC Shares, then the Company  shall, if so requested by WEC, in
    fulfillment of its obligation pursuant to clause (A) of SECTION  7(A)(II)(X)
    (that  is, with respect to the Exercise Price only and without limitation to
    its obligation to pay additional  consideration under clause (B) of  SECTION
    7(A)(II)(X)), redeliver the certificate for such WEC Shares to WEC, free and
    clear of all liens, claims, damages, charges and encumbrances of any kind or
    nature  whatsoever; PROVIDED, HOWEVER, that if  less than all of the Company
    Shares purchased by WEC pursuant to the Company Option are to be repurchased
    pursuant to  this SECTION  7, then  WEC shall  issue to  the Company  a  new
    certificate   representing  those  WEC  Shares  which  are  not  due  to  be
    redelivered to WEC pursuant to this SECTION 7 as they constituted payment of
    the Exercise Price for the Company Shares not being repurchased.

        (c)  PAYMENT AND REDELIVERY OF COMPANY  OPTION OR SHARES.  In the  event
    WEC  exercises its rights under this SECTION 7, the Company shall, within 10
    business days  thereafter, pay  the required  amount to  WEC in  immediately
    available funds and WEC shall surrender to the Company the Company Option or
    the  certificates evidencing  the Company  Shares purchased  by WEC pursuant
    thereto, and  WEC shall  warrant that  it owns  the Company  Option or  such
    shares and that the Company Option or such shares are then free and clear of
    all  liens, claims, damages, charges and  encumbrances of any kind or nature
    whatsoever.

        (d)  WEC CALL.  If WEC  has elected to purchase Company Shares  pursuant
    to  the exercise of the  Company Option by the  issuance and delivery of WEC
    Shares, notwithstanding that WEC may no longer hold any such Company  Shares
    or  that WEC elects not  to exercise its other  rights under this SECTION 7,
    WEC may require, at any  time or from time to  time prior to April 30,  1997
    (provided  that such date  shall be extended  to October 31,  1997 under the
    circumstances where  the date  after which  either party  may terminate  the
    Merger Agreement pursuant to Section 9.1(b) of the Merger Agreement has been
    extended  to October  31, 1997),  the Company  to sell  to WEC  any such WEC
    Shares at the price attributed to such WEC Shares pursuant to SECTION 4 plus
    interest at the rate of 6.5% per annum on such amount from the Closing  Date
    relating  to the exchange  of such WEC  Shares pursuant to  SECTION 4 to the
    closing date under this SECTION 7(D)  less any dividends on such WEC  Shares
    paid during such period or declared and payable to stockholders of record on
    a date during such period.

                                      B-5
<PAGE>
        (e)    REPURCHASE PRICE  REDUCED  AT WEC'S  OPTION.   In  the  event the
    repurchase price specified in SECTION  7(A) would subject the repurchase  of
    the  Company Option or the  Company Shares purchased by  WEC pursuant to the
    Company Option to  a vote  of the shareholders  of the  Company pursuant  to
    Section 302A.553, Subd. 3 of the MBCA, then WEC may, at its election, reduce
    the repurchase price to an amount which would permit such repurchase without
    the necessity for such a shareholder vote.

        8.   VOTING OF SHARES.  Following the date hereof and prior to the fifth
    anniversary of the  date hereof  (the "EXPIRATION DATE"),  each party  shall
    vote  any shares of capital stock of  the other party acquired by such party
    pursuant to  this Agreement,  including any  WEC Shares  issued pursuant  to
    SECTION  1(B) ("RESTRICTED SHARES") or  otherwise beneficially owned (within
    the meaning of Rule 13d-3 promulgated  under the Securities Exchange Act  of
    1934,  as  amended  (the  "EXCHANGE  ACT")) by  such  party  on  each matter
    submitted to a vote of shareholders of such other party for and against such
    matter in the same proportion as the vote of all other shareholders of  such
    other  party are voted (whether by proxy  or otherwise) for and against such
    matter.

        9.  RESTRICTIONS ON TRANSFER.

        (a)  RESTRICTIONS ON  TRANSFER.  Prior to  the Expiration Date,  neither
    party shall, directly or indirectly, by operation of law or otherwise, sell,
    assign,  pledge, or otherwise  dispose of or  transfer any Restricted Shares
    beneficially owned by such party, other  than (i) pursuant to SECTION 7,  or
    (ii) in accordance with SECTION 9(B) or SECTION 10.

        (b)    PERMITTED  SALES.    Following  the  termination  of  the  Merger
    Agreement, a  party  shall  be  permitted  to  sell  any  Restricted  Shares
    beneficially  owned  by it  if such  sale is  made pursuant  to a  tender or
    exchange  offer  that  has  been  approved  or  recommended,  or   otherwise
    determined  to be fair to  and in the best  interests of the shareholders of
    the other party, by a majority of  the members of the Board of Directors  of
    such  other party which  majority shall include a  majority of directors who
    were directors prior to the announcement of such tender or exchange offer.

        10.   REGISTRATION RIGHTS.    Following the  termination of  the  Merger
    Agreement,  each party hereto (a "DESIGNATED  HOLDER") may by written notice
    (the "REGISTRATION NOTICE")  to the other  party (the "REGISTRANT")  request
    the  Registrant to register under the Securities  Act all or any part of the
    Restricted  Shares  beneficially  owned  by  such  Designated  Holder   (the
    "REGISTRABLE   SECURITIES")  pursuant   to  a  bona   fide  firm  commitment
    underwritten  public  offering  in  which  the  Designated  Holder  and  the
    underwriters  shall  effect  as  wide  a  distribution  of  such Registrable
    Securities as is reasonably practicable and shall use their best efforts  to
    prevent  any person (including  any Group (as  used in Rule  13d-5 under the
    Exchange Act))  and its  affiliates from  purchasing through  such  offering
    Restricted  Shares representing  more than 1%  of the  outstanding shares of
    common stock  of the  Registrant  on a  fully  diluted basis  (a  "PERMITTED
    OFFERING").  The Registration Notice shall include a certificate executed by
    the  Designated  Holder  and   its  proposed  managing  underwriter,   which
    underwriter  shall be  an investment  banking firm  of nationally recognized
    standing (the "MANAGER"), stating that (i) they have a good faith  intention
    to commence promptly a Permitted Offering and (ii) the Manager in good faith
    believes  that, based on  the then prevailing market  conditions, it will be
    able to sell the  Registrable Securities at  a per share  price equal to  at
    least  80% of  the then  Fair Market  Value of  such shares.  The Registrant
    (and/or any person designated  by the Registrant)  shall thereupon have  the
    option  exercisable  by written  notice delivered  to the  Designated Holder
    within 10  business  days after  the  receipt of  the  Registration  Notice,
    irrevocably  to  agree  to  purchase  all or  any  part  of  the Registrable
    Securities proposed to be so sold for  cash at a price (the "OPTION  PRICE")
    equal  to the product of  (i) the number of  Registrable Securities to be so
    purchased by the  Registrant and  (ii) the then  Fair Market  Value of  such
    shares.  Any such purchase  of Registrable Securities  by the Registrant (or
    its designee) hereunder  shall take place  at a  closing to be  held at  the
    principal  executive  offices of  the Registrant  or at  the offices  of its
    counsel   at   any   reasonable   date   and   time   designated   by    the

                                      B-6
<PAGE>
    Registrant and/or such designee in such notice within 20 business days after
    delivery of such notice. Any payment for the shares to be purchased shall be
    made  by  delivery  at the  time  of such  closing  of the  Option  Price in
    immediately available funds.

        If the Registrant does not elect to exercise its option pursuant to this
    SECTION 10 with respect to all Registrable Securities, it shall use its best
    efforts to effect, as  promptly as practicable,  the registration under  the
    Securities  Act of the unpurchased Registrable  Securities proposed to be so
    sold; PROVIDED, HOWEVER, that  (i) neither party shall  be entitled to  more
    than  an aggregate  of two  effective registration  statements hereunder and
    (ii) the  Registrant will  not be  required to  file any  such  registration
    statement  during  any period  of time  (not  to exceed  40 days  after such
    request in the case of  clause (A) below or 90  days in the case of  clauses
    (B)  and (C)  below) when  (A) the Registrant  is in  possession of material
    non-public information which it reasonably believes would be detrimental  to
    be  disclosed at such time and, in the opinion of counsel to the Registrant,
    such information would have to be disclosed if a registration statement were
    filed at that time; (B) the Registrant is required under the Securities  Act
    to  include audited financial statements for any period in such registration
    statement and such financial statements are not yet available for  inclusion
    in  such registration  statement; or (C)  the Registrant  determines, in its
    reasonable  judgment,  that  such  registration  would  interfere  with  any
    financing,   acquisition  or   other  material   transaction  involving  the
    Registrant or any of its affiliates. The Registrant shall use its reasonable
    best efforts to cause any Registrable Securities registered pursuant to this
    SECTION 10 to be qualified for sale under the securities or Blue-Sky laws of
    such jurisdictions as the Designated Holder may reasonably request and shall
    continue such registration or qualification in effect in such  jurisdiction;
    PROVIDED,  HOWEVER, that the Registrant shall  not be required to qualify to
    do  business  in,  or  consent  to  general  service  of  process  in,   any
    jurisdiction by reason of this provision.

        The  registration rights set forth in this SECTION 10 are subject to the
    condition that the Designated Holder shall provide the Registrant with  such
    information  with respect to such holder's Registrable Securities, the plans
    for the distribution  thereof, and  such other information  with respect  to
    such holder as, in the reasonable judgment of counsel for the Registrant, is
    necessary to enable the Registrant to include in such registration statement
    all  material facts required to be  disclosed with respect to a registration
    thereunder.

        A registration effected under this SECTION  10 shall be effected at  the
    Registrant's  expense, except for underwriting discounts and commissions and
    the fees  and the  expenses of  counsel to  the Designated  Holder, and  the
    Registrant  shall provide to the  underwriters such documentation (including
    certificates, opinions of  counsel and "comfort"  letters from auditors)  as
    are  customary  in connection  with  underwritten public  offerings  as such
    underwriters  may   reasonably  require.   In  connection   with  any   such
    registration,  the  parties  agree  (i)  to  indemnify  each  other  and the
    underwriters in the  customary manner,  (ii) to enter  into an  underwriting
    agreement in form and substance customary for transactions of such type with
    the  Manager and the  other underwriters participating  in such offering and
    (iii) to take  all further actions  which shall be  reasonably necessary  to
    effect  such  registration  and sale  (including,  if the  Manager  deems it
    necessary, participating in road-show presentations).

        The Registrant shall be entitled to include (at its expense)  additional
    shares  of  its common  stock in  a registration  effected pursuant  to this
    SECTION 10  only if  and to  the  extent the  Manager determines  that  such
    inclusion  will  not  adversely affect  the  prospects for  success  of such
    offering.

        11.  ADJUSTMENT UPON CHANGES  IN CAPITALIZATION.  Without limitation  to
    any  restriction on the Company contained in this Agreement or in the Merger
    Agreement, in the event of any change  in Company Common Stock by reason  of
    stock    dividends,   splitups,   mergers    (other   than   the   Mergers),
    recapitalizations, combinations, exchange  of shares or  the like, the  type
    and  number of shares or  securities subject to the  Company Option, and the
    purchase  price  per  share  provided  in  SECTION  1,  shall  be   adjusted
    appropriately to restore to WEC its rights hereunder,

                                      B-7
<PAGE>
    including  the right to purchase from the Company (or its successors) shares
    of Company Common Stock representing 19.9% of the outstanding Company Common
    Stock for the  aggregate Exercise Price  calculated as of  the date of  this
    Agreement as provided in SECTION 1.

        12.    RESTRICTIVE LEGENDS.    Each certificate  representing  shares of
    Company Common  Stock issued  to  WEC hereunder,  and  WEC Shares,  if  any,
    delivered   to  the  Company  at  a  Closing,  shall  include  a  legend  in
    substantially the following form:

           THE  SECURITIES  REPRESENTED  BY  THIS  CERTIFICATE  HAVE  NOT   BEEN
       REGISTERED  UNDER  THE SECURITIES  ACT OF  1933, AS  AMENDED, AND  MAY BE
       REOFFERED OR SOLD  ONLY IF  SO REGISTERED OR  IF AN  EXEMPTION FROM  SUCH
       REGISTRATION IS AVAILABLE. SUCH SECURITIES ARE ALSO SUBJECT TO ADDITIONAL
       RESTRICTIONS  ON TRANSFER  AS SET  FORTH IN  THE STOCK  OPTION AGREEMENT,
       DATED AS OF  APRIL 28, 1995,  A COPY OF  WHICH MAY BE  OBTAINED FROM  THE
       ISSUER UPON REQUEST.

    It  is  understood  and  agreed  that:  (i)  the  reference  to  the  resale
    restrictions of the Securities Act in  the above legend shall be removed  by
    delivery  of substitute certificate(s) without such  reference if WEC or the
    Company, as the case may be, shall have delivered to the other party a  copy
    of  a letter from the staff of the Securities and Exchange Commission, or an
    opinion of counsel, in form and  substance satisfactory to the other  party,
    to  the  effect  that  such  legend is  not  required  for  purposes  of the
    Securities Act; (ii) the  reference to the provisions  to this Agreement  in
    the  above legend shall be removed  by delivery of substitute certificate(s)
    without such  reference if  the  shares have  been  sold or  transferred  in
    compliance  with the  provisions of  this Agreement  and under circumstances
    that do not require  the retention of such  reference; and (iii) the  legend
    shall  be removed in its entirety if the conditions in the preceding clauses
    (i) and (ii) are both satisfied.  In addition, such certificates shall  bear
    any other legend as may be required by law. Certificates representing shares
    sold  in a registered  public offering pursuant  to SECTION 10  shall not be
    required to bear the legend set forth in this SECTION 12.

        13.  BINDING EFFECT; NO ASSIGNMENT; NO THIRD PARTY BENEFICIARIES.   This
    Agreement  shall be  binding upon  and inure to  the benefit  of the parties
    hereto and  their respective  successors and  permitted assigns.  Except  as
    expressly  provided for  in this Agreement,  neither this  Agreement nor the
    rights or the obligations of either  party hereto are assignable, except  by
    operation  of law, or with  the written consent of  the other party. Nothing
    contained in this Agreement, express or implied, is intended to confer  upon
    any  person other  than the  parties hereto  and their  respective permitted
    assigns any rights or  remedies of any nature  whatsoever by reason of  this
    Agreement.  Any Restricted  Shares sold  by a  party in  compliance with the
    provisions of SECTION 10 shall, upon  consummation of such sale, be free  of
    the  restrictions imposed  with respect  to such  shares by  this Agreement,
    unless and  until  such  party  shall repurchase  or  otherwise  become  the
    beneficial owner of such shares, and any transferee of such shares shall not
    be entitled to the registration rights of such party.

        14.   SPECIFIC PERFORMANCE.  The parties recognize and agree that if for
    any reason any  of the  provisions of this  Agreement are  not performed  in
    accordance  with their specific  terms or are  otherwise breached, immediate
    and irreparable harm or injury would be caused for which money damages would
    not be an adequate remedy. Accordingly, each party agrees that, in  addition
    to  other  remedies, the  other  party shall  be  entitled to  an injunction
    restraining any violation or threatened violation of the provisions of  this
    Agreement.  In the  event that  any action  should be  brought in  equity to
    enforce the provisions of the Agreement, neither party will allege, and each
    party hereby waives the defense, that there is adequate remedy at law.

        15.  ENTIRE AGREEMENT.  This Agreement, the WEC Stock Option  Agreement,
    the  Confidentiality  Agreement  and  the  Merger  Agreement  (including the
    exhibits and schedules thereto)

                                      B-8
<PAGE>
    constitute the  entire  agreement among  the  parties with  respect  to  the
    subject  matter hereof and thereof and  supersede all other prior agreements
    and understandings, both written and oral, among the parties or any of  them
    with respect to the subject matter hereof and thereof.

        16.   FURTHER ASSURANCES.  Each party  will execute and deliver all such
    further documents and instruments and take all such further action as may be
    necessary in order to consummate the transactions contemplated hereby.

        17.  VALIDITY.  The invalidity  or unenforceability of any provision  of
    this  Agreement shall not affect the validity or enforceability of the other
    provisions of this Agreement, which shall  remain in full force and  effect.
    In  the event any court or other competent authority holds any provisions of
    this Agreement to be null, void  or unenforceable, the parties hereto  shall
    negotiate  in good faith the execution and  delivery of an amendment to this
    Agreement in order,  as nearly  as possible,  to effectuate,  to the  extent
    permitted  by law,  the intent  of the parties  hereto with  respect to such
    provision and the economic effects thereof. If for any reason any such court
    or regulatory agency determines that WEC is not permitted to acquire, or the
    Company is  not permitted  to repurchase  pursuant to  SECTION 7,  the  full
    number  of shares of Company  Common Stock provided in  SECTION 1 hereof (as
    the same may be  adjusted), it is  the express intention  of the Company  to
    allow  WEC to acquire  or to require  the Company to  repurchase such lesser
    number  of  shares  as  may   be  permissible,  without  any  amendment   or
    modification  hereof.  Each party  agrees that,  should  any court  or other
    competent authority hold any provision of  this Agreement or part hereof  to
    be  null,  void or  unenforceable, or  order  any party  to take  any action
    inconsistent herewith, or  not take  any action required  herein, the  other
    party  shall not  be entitled to  specific performance of  such provision or
    part hereof  or to  any other  remedy, including  but not  limited to  money
    damages,  for breach hereof or  of any other provision  of this Agreement or
    part hereof as the result of such holding or order.

        18.  NOTICES.  All notices  and other communications hereunder shall  be

    by and  construed in  accordance with  the laws  of the  State of  New  York
    applicable to agreements made and to be performed entirely within such State
    and  without regard  to its  choice of law  principles. Each  of the parties
    hereto (a) consents  to submit itself  to the personal  jurisdiction of  any
    federal  court located in the State of New  York or any New York state court
    in the  event  any dispute  arises  out of  this  Agreement or  any  of  the
    transactions  contemplated by  this Agreement, (b)  agrees that  it will not
    attempt to deny  or defeat  such personal  jurisdiction by  motion or  other
    request  for leave from any such court and (c) agrees that it will not bring
    any  action  relating  to  this   Agreement  or  any  of  the   transactions
    contemplated  by  this Agreement  in any  court other  than a  federal court
    sitting in the State of New York or a New York state court.

        20.  INTERPRETATION.  When  a reference is made  in this Agreement to  a
    Section  such  reference shall  be  to a  Section  of this  Agreement unless

    are used in this Agreement, they shall be deemed to be followed by the words
    "without limitation".  The  descriptive  headings herein  are  inserted  for
    convenience  of reference  only and  are not  intended to  be part  of or to
    affect the meaning or interpretation of this Agreement.

        21.  COUNTERPARTS.  This Agreement may be executed in two  counterparts,

    Exchange Act by reason of such exercise.

        25.  REPLACEMENT  OF COMPANY  OPTION.  Upon  receipt by  the Company  of
    evidence  reasonably satisfactory to  it of the  loss, theft, destruction or
    mutilation  of  this  Agreement,  and  (in  the  case  of  loss,  theft   or
    destruction)  of reasonably satisfactory indemnification, and upon surrender
    and cancellation of this Agreement,  if mutilated, the Company will  execute
    and deliver a new Agreement of like tenor and date.

    IN  WITNESS WHEREOF,  the parties  hereto have  caused this  Agreement to be
executed by their respective duly authorized officers as of the date first above
written.

                           WEC STOCK OPTION AGREEMENT

    STOCK  OPTION AGREEMENT, dated  as of April  28, 1995 by  and among Northern
States Power  Company, a  Minnesota corporation  ("NSP"), and  Wisconsin  Energy
Corporation, a Wisconsin corporation (the "COMPANY").

    WHEREAS, concurrently with the execution and delivery of this Agreement, (i)
NSP,  the Company, Northern Power Wisconsin Corp., a Wisconsin corporation ("NEW
NSP") and WEC Sub Corp., a Wisconsin corporation ("WEC SUB"), are entering  into
an  Agreement  and Plan  of Merger,  dated as  of the  date hereof  (the "MERGER
AGREEMENT"), which provides, among other things,  upon the terms and subject  to
the  conditions thereof,  for the merger  of NSP with  and into New  NSP and the
merger of WEC Sub with  and into New NSP (the  "MERGERS"), and (ii) the  Company
and  NSP are entering into a certain stock option agreement dated as of the date
hereof whereby  NSP grants  to the  Company an  option with  respect to  certain
shares  of NSP's  common stock on  the terms  and subject to  the conditions set
forth therein (the "NSP STOCK OPTION AGREEMENT"); and

    WHEREAS, as  a condition  to  NSP's willingness  to  enter into  the  Merger
Agreement,  NSP has  requested that  the Company agree,  and the  Company has so
agreed, to  grant  to NSP  an  option with  respect  to certain  shares  of  the
Company's  common stock, on  the terms and  subject to the  conditions set forth
herein.

    NOW, THEREFORE, to  induce NSP to  enter into the  Merger Agreement, and  in
consideration of the mutual covenants and agreements set forth herein and in the
Merger Agreement, the parties hereto agree as follows:

        1.   GRANT  OF OPTION.   The  Company hereby  grants NSP  an irrevocable
    option (the "COMPANY OPTION") to  purchase up to 21,773,726 shares,  subject
    to  adjustment  as provided  in SECTION  11 (such  shares being  referred to
    herein as the "COMPANY SHARES") of  common stock, par value $.01 per  share,
    of  the Company (the "COMPANY  COMMON STOCK") (being 19.9%  of the number of
    shares of Company Common Stock outstanding on the date hereof) in the manner
    set forth  below at  a price  (the "EXERCISE  PRICE") per  Company Share  of
    $27.675  (which is equal  to the Fair  Market Value (as  defined below) of a
    Company Share on the date hereof) payable,  at NSP's option, (a) in cash  or
    (b)   subject  to  the  Company's  having  obtained  the  approvals  of  any
    Governmental Authority required for  the Company to  acquire the NSP  Shares
    (as  defined below)  from NSP,  which approvals  the Company  shall use best
    efforts to obtain, in shares of common stock, par value $2.50 per share,  of
    NSP  ("NSP  SHARES") in  either case  in accordance  with Section  4 hereof.
    Notwithstanding the  foregoing, in  no  event shall  the number  of  Company
    Shares  for  which the  Company Option  is exercisable  exceed 19.9%  of the
    number of issued  and outstanding shares  of Company Common  Stock. As  used
    herein,  the "FAIR MARKET  VALUE" of any  share shall be  the average of the
    daily closing sales price for such share on the New York Stock Exchange (the
    "NYSE") during the 10 NYSE trading days prior to the fifth NYSE trading  day
    preceding  the date such Fair Market  Value is to be determined. Capitalized
    terms used herein but not defined  herein shall have the meanings set  forth
    in the Merger Agreement.

        2.   EXERCISE OF OPTION.  The Company Option may be exercised by NSP, in
    whole or  in part,  at  any time  or  from time  to  time after  the  Merger
    Agreement  becomes terminable by NSP under circumstances which could entitle
    NSP to termination fees under either Section 9.3(a) of the Merger  Agreement
    (provided  that the events specified in  Section 9.3(a)(ii)(x) of the Merger
    Agreement shall  have occurred,  although the  events specified  in  Section
    9.3(a)(ii)(y)  thereof  need not  have occurred)  or  Section 9.3(b)  of the
    Merger Agreement (regardless  of whether  the Merger  Agreement is  actually
    terminated  or whether  there occurs a  closing of  any Business Combination
    involving a Target  Party or a  closing by  which a Target  Party becomes  a
    subsidiary),  any  such  event  by which  the  Merger  Agreement  becomes so
    terminable by NSP being referred to herein as a "TRIGGER EVENT." The Company
    shall  notify   NSP  promptly   in  writing   of  the   occurrence  of   any

                                      C-1
<PAGE>
    Trigger  Event, it being  understood that the  giving of such  notice by the
    Company shall not be a condition to the right of NSP to exercise the Company
    Option. In the event  NSP wishes to exercise  the Company Option, NSP  shall
    deliver  to the Company  a written notice  (an "EXERCISE NOTICE") specifying
    the total number of Company Shares it wishes to purchase. Each closing of  a
    purchase  of Company Shares (a "CLOSING") shall  occur at a place, on a date
    and at a time designated by NSP in an Exercise Notice delivered at least two
    business days prior  to the date  of the Closing.  The Company Option  shall
    terminate  upon the earlier of: (i) the Effective Time; (ii) the termination
    of the Merger Agreement pursuant to Section 9.1 thereof (other than upon  or
    during  the continuance of a Trigger Event); or (iii) 180 days following any
    termination of the  Merger Agreement  upon or  during the  continuance of  a
    Trigger  Event (or if, at the expiration  of such 180 day period the Company
    Option cannot be  exercised by  reason of any  applicable judgment,  decree,
    order, law or regulation, 10 business days after such impediment to exercise
    shall  have  been removed  or shall  have  become final  and not  subject to
    appeal, but  in no  event under  this clause  (iii) later  than October  31,
    1997).  Notwithstanding  the  foregoing,  the  Company  Option  may  not  be
    exercised  if  NSP   is  in  material   breach  of  any   of  its   material
    representations or warranties, or in material breach of any of its covenants
    or  agreements, contained in this Agreement or in the Merger Agreement. Upon
    the giving by NSP to  the Company of the Exercise  Notice and the tender  of
    the  applicable  aggregate Exercise  Price, NSP  shall be  deemed to  be the
    holder of  record  of  the  Company  Shares  issuable  upon  such  exercise,
    notwithstanding  that the stock transfer books  of the Company shall then be
    closed or that certificates representing such Company Shares shall not  then
    be actually delivered to NSP.

        3.   CONDITIONS TO CLOSING.  The  obligation of the Company to issue the
    Company Shares to NSP hereunder is  subject to the conditions, which  (other
    than  the conditions described in clauses (i),  (iii) and (iv) below) may be
    waived by the Company in its sole discretion, that (i) all waiting  periods,
    if  any, under the HSR Act, applicable to the issuance of the Company Shares
    hereunder shall  have expired  or  have been  terminated; (ii)  the  Company
    Shares,  and any  NSP Shares  which are  issued in  payment of  the Exercise
    Price, shall have been approved for listing on the NYSE upon official notice
    of issuance; (iii) all consents, approvals, orders or authorizations of,  or
    registrations,  declarations or  filings with,  any federal,  state or local
    administrative  agency  or  commission  or  other  federal  state  or  local
    Governmental  Authority, if any, required in connection with the issuance of
    the Company Shares hereunder shall have  been obtained or made, as the  case
    may be, including, without limitation, the approval of the SEC under Section
    10  of the 1935 Act of the acquisition  of the Company Shares by NSP and, if
    applicable, the acquisition by  the Company of  the NSP Shares  constituting
    the   Exercise  Price  hereunder;  and  (iv)  no  preliminary  or  permanent
    injunction or other order by any court of competent jurisdiction prohibiting
    or otherwise restraining such issuance shall be in effect.

        4.  CLOSING.  At any Closing, (a) the Company will deliver to NSP or its
    designee a single certificate in definitive form representing the number  of
    the   Company  Shares  designated  by  NSP  in  its  Exercise  Notice,  such
    certificate to be registered in the name  of NSP and to bear the legend  set
    forth  in SECTION 12, and (b) NSP  will deliver to the Company the aggregate
    price for the Company Shares so  designated and being purchased by (i)  wire
    transfer  of immediately available funds or certified check or bank check or
    (ii) subject to the condition in SECTION 1(B), a certificate or certificates
    representing the number of NSP Shares  being issued by NSP in  consideration
    thereof,  as the case may be. For the purposes of this Agreement, the number
    of NSP Shares to be delivered to the Company shall be equal to the  quotient
    obtained  by dividing (i)  the product of  (x) the number  of Company Shares
    with respect to  which the  Company Option is  being exercised  and (y)  the
    Exercise  Price by (ii) the Fair Market Value  of the NSP Shares on the date
    immediately preceding  the date  the  Exercise Notice  is delivered  to  the
    Company.  The Company shall pay all expenses,  and any and all United States
    federal, state and  local taxes  and other charges  that may  be payable  in
    connection  with the preparation,  issue and delivery  of stock certificates
    under this Section 4 in the name of NSP or its designee.

        7.  CERTAIN REPURCHASES.

        (a)   NSP  PUT.  At  the request  of NSP by  written notice  at any time
    during which the Company  Option is exercisable pursuant  to SECTION 2  (the
    "REPURCHASE  PERIOD"), the Company  (or any successor  entity thereof) shall
    repurchase from NSP all or any portion  of the Company Option, at the  price
    set  forth in subparagraph (i)  below, or, at the  request of NSP by written
    notice at any time prior to April 30, 1997 (provided that such date shall be
    extended to October 31,  1997 under the circumstances  where the date  after
    which  either party may  terminate the Merger  Agreement pursuant to Section
    9.1(b)  of  the  Merger   Agreement  has  been   extended  to  October   31,

                                      C-4
<PAGE>
    1997),  the Company (or any successor  entity thereof) shall repurchase from
    NSP all or any portion  of the Company Shares  purchased by NSP pursuant  to
    the Company Option, at the price set forth in subparagraph (ii) below:

           (i)  the difference  between the  "MARKET/OFFER PRICE"  for shares of
       Company Common Stock as  of the date  NSP gives notice  of its intent  to
       exercise  its rights under this  SECTION 7 (defined as  the higher of (A)
       the price per share  offered as of  such date pursuant  to any tender  or
       exchange  offer or  other offer  with respect  to a  Business Combination
       which was made prior to such date  and not terminated or withdrawn as  of
       such  date (the "OFFER PRICE")  and (B) the Fair  Market Value of Company
       Common Stock  as of  such date  (the "MARKET  PRICE")) and  the  Exercise
       Price, multiplied by the number of Company Shares purchasable pursuant to
       the  Company  Option (or  portion thereof  with respect  to which  NSP is
       exercising its rights under this SECTION 7), but only if the Market/Offer
       Price is greater than the Exercise Price;

           (ii) the product of (x) the sum of (A) the Exercise Price paid by NSP
       per Company Share  acquired pursuant to  the Company Option  and (B)  the
       difference  between the  Market/Offer Price  and the  Exercise Price, but
       only if the Market/Offer  Price is greater than  the Exercise Price,  and
       (y)  the number of Company  Shares so to be  repurchased pursuant to this
       SECTION 7. For purposes of this clause (ii), the Offer Price shall be the
       highest price per share offered pursuant to a tender or exchange offer or
       other Business Combination  offer during the  Repurchase Period prior  to
       the delivery by NSP of a notice of repurchase.

        (b)   REDELIVERY  OF NSP  SHARES.   If NSP  elected to  purchase Company
    Shares pursuant to the  exercise of the Company  Option by the issuance  and
    delivery  of NSP Shares, then the Company  shall, if so requested by NSP, in
    fulfillment of its obligation pursuant to clause (A) of SECTION  7(A)(II)(X)
    (that  is, with respect to the Exercise Price only and without limitation to
    its obligation to pay additional  consideration under clause (B) of  SECTION
    7(A)(II)(X)), redeliver the certificate for such NSP Shares to NSP, free and
    clear of all liens, claims, damages, charges and encumbrances of any kind or
    nature  whatsoever; PROVIDED, HOWEVER, that if  less than all of the Company
    Shares purchased by NSP pursuant to the Company Option are to be repurchased
    pursuant to  this SECTION  7, then  NSP shall  issue to  the Company  a  new
    certificate   representing  those  NSP  Shares  which  are  not  due  to  be
    redelivered to NSP pursuant to this SECTION 7 as they constituted payment of
    the Exercise Price for the Company Shares not being repurchased.

        (c)  PAYMENT AND REDELIVERY OF COMPANY  OPTION OR SHARES.  In the  event
    NSP  exercises its rights under this SECTION 7, the Company shall, within 10
    business days  thereafter, pay  the required  amount to  NSP in  immediately
    available funds and NSP shall surrender to the Company the Company Option or
    the  certificates evidencing  the Company  Shares purchased  by NSP pursuant
    thereto, and  NSP shall  warrant that  it owns  the Company  Option or  such
    shares and that the Company Option or such shares are then free and clear of
    all  liens, claims, damages, charges and  encumbrances of any kind or nature
    whatsoever.

        (d)  NSP CALL.  If NSP  has elected to purchase Company Shares  pursuant
    to  the exercise of the  Company Option by the  issuance and delivery of NSP
    Shares, notwithstanding that NSP may no longer hold any such Company  Shares
    or  that NSP elects not  to exercise its other  rights under this SECTION 7,
    NSP may require, at any  time or from time to  time prior to April 30,  1997
    (provided  that such date  shall be extended  to October 31,  1997 under the
    circumstances where  the date  after which  either party  may terminate  the
    Merger Agreement pursuant to Section 9.1(b) of the Merger Agreement has been
    extended  to October  31, 1997),  the Company  to sell  to NSP  any such NSP
    Shares at the price attributed to such NSP Shares pursuant to SECTION 4 plus
    interest at the rate of 6.5% per annum on such amount from the Closing  Date
    relating  to the exchange  of such NSP  Shares pursuant to  SECTION 4 to the
    closing date under this SECTION 7(D)  less any dividends on such NSP  Shares
    paid during such period or declared and payable to stockholders of record on
    a date during such period.

        (e)    REPURCHASE PRICE  REDUCED AT  NSP'S OPTION.     In the  event the
    repurchase price specified in SECTION 7(A) would subject the purchase of the
    Company Option or the Company Shares

                                      C-5
<PAGE>
    purchased  by  NSP  pursuant  to  the  Company  Option  to  a  vote  of  the
    shareholders  of the  Company pursuant  to Section  180.1134 of  the WBCL or
    Section  D(1)  of  Article  III  of  the  Company's  Restated  Articles   of
    Incorporation, then NSP may, at its election, reduce the repurchase price to
    an  amount which would permit such repurchase without the necessity for such
    a shareholder vote.

        8.  VOTING OF SHARES.  Following the date hereof and prior to the  fifth
    anniversary  of the  date hereof (the  "EXPIRATION DATE"),  each party shall
    vote any shares of capital stock of  the other party acquired by such  party
    pursuant  to this  Agreement, including  any NSP  Shares issued  pursuant to
    SECTION 1(B) ("RESTRICTED SHARES")  or otherwise beneficially owned  (within
    the  meaning of Rule 13d-3 promulgated  under the Securities Exchange Act of
    1934, as  amended  (the  "EXCHANGE  ACT")) by  such  party  on  each  matter
    submitted to a vote of shareholders of such other party for and against such
    matter  in the same proportion as the vote of all other shareholders of such
    other party are voted (whether by  proxy or otherwise) for and against  such
    matter.

        9.  RESTRICTIONS ON TRANSFER.

        (a)   RESTRICTIONS ON  TRANSFER.  Prior to  the Expiration Date, neither
    party shall, directly or indirectly, by operation of law or otherwise, sell,
    assign, pledge, or otherwise  dispose of or  transfer any Restricted  Shares
    beneficially  owned by such party, other than  (i) pursuant to SECTION 7, or
    (ii) in accordance with SECTION 9(B) or SECTION 10.

        (b)    PERMITTED  SALES.    Following  the  termination  of  the  Merger
    Agreement,  a  party  shall  be  permitted  to  sell  any  Restricted Shares
    beneficially owned  by it  if such  sale is  made pursuant  to a  tender  or
    exchange   offer  that  has  been  approved  or  recommended,  or  otherwise
    determined to be fair to  and in the best  interests of the shareholders  of
    the  other party, by a majority of the  members of the Board of Directors of
    such other party which  majority shall include a  majority of directors  who
    were directors prior to the announcement of such tender or exchange offer.

        10.    REGISTRATION RIGHTS.   Following  the  termination of  the Merger
    Agreement, each party hereto (a  "DESIGNATED HOLDER") may by written  notice
    (the  "REGISTRATION NOTICE") to  the other party  (the "REGISTRANT") request
    the Registrant to register under the Securities  Act all or any part of  the
    Restricted   Shares  beneficially  owned  by  such  Designated  Holder  (the
    "REGISTRABLE  SECURITIES")  pursuant   to  a  bona   fide  firm   commitment
    underwritten  public  offering  in  which  the  Designated  Holder  and  the
    underwriters shall  effect  as  wide  a  distribution  of  such  Registrable
    Securities  as is reasonably practicable and shall use their best efforts to
    prevent any person  (including any Group  (as used in  Rule 13d-5 under  the
    Exchange  Act))  and its  affiliates from  purchasing through  such offering
    Restricted Shares representing  more than  1% of the  outstanding shares  of
    common  stock  of the  Registrant  on a  fully  diluted basis  (a "PERMITTED
    OFFERING"). The Registration Notice shall include a certificate executed  by
    the   Designated  Holder  and  its   proposed  managing  underwriter,  which
    underwriter shall be  an investment  banking firm  of nationally  recognized
    standing  (the "MANAGER"), stating that (i) they have a good faith intention
    to commence promptly a Permitted Offering and (ii) the Manager in good faith
    believes that, based on  the then prevailing market  conditions, it will  be
    able  to sell the  Registrable Securities at  a per share  price equal to at
    least 80%  of the  then Fair  Market Value  of such  shares. The  Registrant
    (and/or  any person designated  by the Registrant)  shall thereupon have the
    option exercisable  by written  notice delivered  to the  Designated  Holder
    within  10  business  days after  the  receipt of  the  Registration Notice,
    irrevocably to  agree  to  purchase  all or  any  part  of  the  Registrable
    Securities  proposed to be so sold for  cash at a price (the "OPTION PRICE")
    equal to the product of  (i) the number of  Registrable Securities to be  so
    purchased  by the  Registrant and  (ii) the then  Fair Market  Value of such
    shares. Any such purchase  of Registrable Securities  by the Registrant  (or
    its  designee) hereunder  shall take place  at a  closing to be  held at the
    principal executive  offices of  the Registrant  or at  the offices  of  its
    counsel    at   any   reasonable   date   and   time   designated   by   the

                                      C-6
<PAGE>
    Registrant and/or such designee in such notice within 20 business days after
    delivery of such notice. Any payment for the shares to be purchased shall be
    made by  delivery  at the  time  of such  closing  of the  Option  Price  in
    immediately available funds.

        If the Registrant does not elect to exercise its option pursuant to this
    SECTION 10 with respect to all Registrable Securities, it shall use its best
    efforts  to effect, as  promptly as practicable,  the registration under the
    Securities Act of the unpurchased  Registrable Securities proposed to be  so
    sold;  PROVIDED, HOWEVER, that  (i) neither party shall  be entitled to more
    than an aggregate  of two  effective registration  statements hereunder  and
    (ii)  the  Registrant will  not be  required to  file any  such registration
    statement during  any period  of time  (not  to exceed  40 days  after  such
    request  in the case of clause  (A) below or 90 days  in the case of clauses
    (B) and (C)  below) when  (A) the Registrant  is in  possession of  material
    non-public  information which it reasonably believes would be detrimental to
    be disclosed at such time and, in the opinion of counsel to the  Registrant,
    such information would have to be disclosed if a registration statement were
    filed  at that time; (B) the Registrant is required under the Securities Act
    to include audited financial statements for any period in such  registration
    statement  and such financial statements are not yet available for inclusion
    in such registration  statement; or  (C) the Registrant  determines, in  its
    reasonable  judgment,  that  such  registration  would  interfere  with  any
    financing,  acquisition  or   other  material   transaction  involving   the
    Registrant or any of its affiliates. The Registrant shall use its reasonable
    best efforts to cause any Registrable Securities registered pursuant to this
    SECTION 10 to be qualified for sale under the securities or Blue-Sky laws of
    such jurisdictions as the Designated Holder may reasonably request and shall
    continue  such registration or qualification in effect in such jurisdiction;
    PROVIDED, HOWEVER, that the Registrant shall  not be required to qualify  to
    do   business  in,  or  consent  to  general  service  of  process  in,  any
    jurisdiction by reason of this provision.

        The registration rights set forth in this SECTION 10 are subject to  the
    condition  that the Designated Holder shall provide the Registrant with such
    information with respect to such holder's Registrable Securities, the  plans
    for  the distribution  thereof, and such  other information  with respect to
    such holder as, in the reasonable judgment of counsel for the Registrant, is
    necessary to enable the Registrant to include in such registration statement
    all material facts required to be  disclosed with respect to a  registration
    thereunder.

        A  registration effected under this SECTION  10 shall be effected at the
    Registrant's expense, except for underwriting discounts and commissions  and
    the  fees and  the expenses  of counsel  to the  Designated Holder,  and the
    Registrant shall provide to  the underwriters such documentation  (including
    certificates,  opinions of counsel  and "comfort" letters  from auditors) as
    are customary  in  connection with  underwritten  public offerings  as  such
    underwriters   may  reasonably   require.  In   connection  with   any  such
    registration, the  parties  agree  (i)  to  indemnify  each  other  and  the
    underwriters  in the  customary manner, (ii)  to enter  into an underwriting
    agreement in form and substance customary for transactions of such type with
    the Manager and the  other underwriters participating  in such offering  and
    (iii)  to take  all further actions  which shall be  reasonably necessary to
    effect such  registration  and sale  (including,  if the  Manager  deems  it
    necessary, participating in road-show presentations).

        The  Registrant shall be entitled to include (at its expense) additional
    shares of  its common  stock in  a registration  effected pursuant  to  this
    SECTION  10  only if  and to  the  extent the  Manager determines  that such
    inclusion will  not  adversely affect  the  prospects for  success  of  such
    offering.

        11.   ADJUSTMENT UPON CHANGES IN  CAPITALIZATION.  Without limitation to
    any restriction on the Company contained in this Agreement or in the  Merger
    Agreement,  in the event of any change  in Company Common Stock by reason of
    stock   dividends,   splitups,   mergers    (other   than   the    Mergers),
    recapitalizations,  combinations, exchange of  shares or the  like, the type
    and number of shares  or securities subject to  the Company Option, and  the
    purchase   price  per  share  provided  in  SECTION  1,  shall  be  adjusted
    appropriately to restore to NSP its rights hereunder,

                                      C-7
<PAGE>
    including the right to purchase from the Company (or its successors)  shares
    of Company Common Stock representing 19.9% of the outstanding Company Common
    Stock  for the aggregate  Exercise Price calculated  as of the  date of this
    Agreement as provided in SECTION 1.

        12.   RESTRICTIVE  LEGENDS.   Each  certificate representing  shares  of
    Company  Common  Stock issued  to  NSP hereunder,  and  NSP Shares,  if any,
    delivered  to  the  Company  at  a  Closing,  shall  include  a  legend   in
    substantially the following form:

           THE   SECURITIES  REPRESENTED  BY  THIS  CERTIFICATE  HAVE  NOT  BEEN
       REGISTERED UNDER  THE SECURITIES  ACT OF  1933, AS  AMENDED, AND  MAY  BE
       REOFFERED  OR SOLD  ONLY IF  SO REGISTERED OR  IF AN  EXEMPTION FROM SUCH
       REGISTRATION IS AVAILABLE. SUCH SECURITIES ARE ALSO SUBJECT TO ADDITIONAL
       RESTRICTIONS ON  TRANSFER AS  SET FORTH  IN THE  STOCK OPTION  AGREEMENT,
       DATED  AS OF  APRIL 28, 1995,  A COPY OF  WHICH MAY BE  OBTAINED FROM THE
       ISSUER UPON REQUEST.

    It  is  understood  and  agreed  that:  (i)  the  reference  to  the  resale
    restrictions  of the Securities Act in the  above legend shall be removed by
    delivery of substitute certificate(s) without  such reference if NSP or  the
    Company,  as the case may be, shall have delivered to the other party a copy
    of a letter from the staff of the Securities and Exchange Commission, or  an
    opinion  of counsel, in form and  substance satisfactory to the other party,
    to the  effect  that  such  legend  is not  required  for  purposes  of  the
    Securities  Act; (ii) the  reference to the provisions  to this Agreement in
    the above legend shall be  removed by delivery of substitute  certificate(s)
    without  such  reference if  the  shares have  been  sold or  transferred in
    compliance with the  provisions of  this Agreement  and under  circumstances
    that  do not require the  retention of such reference;  and (iii) the legend
    shall be removed in its entirety if the conditions in the preceding  clauses
    (i)  and (ii) are both satisfied.  In addition, such certificates shall bear
    any other legend as may be required by law. Certificates representing shares
    sold in a  registered public offering  pursuant to SECTION  10 shall not  be
    required to bear the legend set forth in this SECTION 12.

        13.   BINDING EFFECT; NO ASSIGNMENT; NO THIRD PARTY BENEFICIARIES.  This
    Agreement shall be  binding upon  and inure to  the benefit  of the  parties
    hereto  and  their respective  successors and  permitted assigns.  Except as
    expressly provided for  in this  Agreement, neither this  Agreement nor  the
    rights  or the obligations of either  party hereto are assignable, except by
    operation of law, or  with the written consent  of the other party.  Nothing
    contained  in this Agreement, express or implied, is intended to confer upon
    any person  other than  the parties  hereto and  their respective  permitted
    assigns  any rights or remedies  of any nature whatsoever  by reason of this
    Agreement. Any Restricted  Shares sold  by a  party in  compliance with  the
    provisions  of SECTION 10 shall, upon consummation  of such sale, be free of
    the restrictions  imposed with  respect to  such shares  by this  Agreement,
    unless  and  until  such  party shall  repurchase  or  otherwise  become the
    beneficial owner of such shares, and any transferee of such shares shall not
    be entitled to the registration rights of such party.

        14.  SPECIFIC PERFORMANCE.  The parties recognize and agree that if  for
    any  reason any  of the  provisions of this  Agreement are  not performed in
    accordance with their  specific terms or  are otherwise breached,  immediate
    and irreparable harm or injury would be caused for which money damages would
    not  be an adequate remedy. Accordingly, each party agrees that, in addition
    to other  remedies, the  other  party shall  be  entitled to  an  injunction
    restraining  any violation or threatened violation of the provisions of this
    Agreement. In  the event  that any  action should  be brought  in equity  to
    enforce the provisions of the Agreement, neither party will allege, and each
    party hereby waives the defense, that there is adequate remedy at law.

        15.   ENTIRE AGREEMENT.  This Agreement, the NSP Stock Option Agreement,
    the Confidentiality  Agreement  and  the  Merger  Agreement  (including  the
    exhibits and schedules thereto)

                                      C-8
<PAGE>
    constitute  the  entire  agreement among  the  parties with  respect  to the
    subject matter hereof and thereof  and supersede all other prior  agreements
    and  understandings, both written and oral, among the parties or any of them
    with respect to the subject matter hereof and thereof.

        16.  FURTHER ASSURANCES.  Each  party will execute and deliver all  such
    further documents and instruments and take all such further action as may be
    necessary in order to consummate the transactions contemplated hereby.

        17.   VALIDITY.  The invalidity  or unenforceability of any provision of
    this Agreement shall not affect the validity or enforceability of the  other
    provisions  of this Agreement, which shall  remain in full force and effect.
    In the event any court or other competent authority holds any provisions  of
    this  Agreement to be null, void  or unenforceable, the parties hereto shall
    negotiate in good faith the execution  and delivery of an amendment to  this
    Agreement  in order,  as nearly  as possible,  to effectuate,  to the extent
    permitted by law,  the intent  of the parties  hereto with  respect to  such
    provision and the economic effects thereof. If for any reason any such court
    or regulatory agency determines that NSP is not permitted to acquire, or the
    Company  is  not permitted  to repurchase  pursuant to  SECTION 7,  the full
    number of shares of  Company Common Stock provided  in SECTION 1 hereof  (as
    the  same may be  adjusted), it is  the express intention  of the Company to
    allow NSP to  acquire or to  require the Company  to repurchase such  lesser
    number   of  shares  as  may  be   permissible,  without  any  amendment  or
    modification hereof.  Each party  agrees  that, should  any court  or  other
    competent  authority hold any provision of  this Agreement or part hereof to
    be null,  void or  unenforceable, or  order  any party  to take  any  action
    inconsistent  herewith, or  not take any  action required  herein, the other
    party shall not  be entitled to  specific performance of  such provision  or
    part  hereof or  to any  other remedy,  including but  not limited  to money
    damages, for breach hereof  or of any other  provision of this Agreement  or
    part hereof as the result of such holding or order.

        18.   NOTICES.  All notices  and other communications hereunder shall be

    by  and  construed in  accordance with  the laws  of the  State of  New York
    applicable to agreements made and to be performed entirely within such State

    federal court located in the State of  New York or any New York state  court
    in  the  event  any dispute  arises  out of  this  Agreement or  any  of the
    transactions contemplated by  this Agreement,  (b) agrees that  it will  not
    attempt  to deny  or defeat  such personal  jurisdiction by  motion or other
    request for leave from any such court and (c) agrees that it will not  bring
    any   action  relating  to  this  Agreement   or  any  of  the  transactions
    contemplated by  this Agreement  in any  court other  than a  federal  court
    sitting in the State of New York or a New York state court.

    "without  limitation".  The  descriptive headings  herein  are  inserted for

        21.   COUNTERPARTS.  This Agreement may be executed in two counterparts,

    evidence reasonably satisfactory to  it of the  loss, theft, destruction  or
    mutilation   of  this  Agreement,  and  (in  the  case  of  loss,  theft  or
    destruction) of reasonably satisfactory indemnification, and upon  surrender
    and  cancellation of this Agreement, if  mutilated, the Company will execute
    and deliver a new Agreement of like tenor and date.

    IN WITNESS WHEREOF,  the parties  hereto have  caused this  Agreement to  be
executed by their respective duly authorized officers as of the date first above

(the "Company"),  and  James  J.  Howard (the  "Executive"),  dated  as  of  the
      day of             , 199 .

                          W I T N E S S E T H  T H A T

    WHEREAS,  Northern States Power Company, a Minnesota corporation ("NSP") and
Wisconsin Energy Corporation, a Wisconsin corporation ("WEC") have entered  into
an  Amended and  Restated Agreement and  Plan of  Merger, dated as  of April 28,
1995, as amended  and restated  as of July  26, 1995  (the "Merger  Agreement"),
whereby  the  NSP and  WEC organizations  will  merge, with  the Company  as the
surviving parent; and

    WHEREAS, NSP  and  WEC  wish  to  provide  for  the  orderly  succession  of
management of the Company following the Effective Time (as defined in the Merger
Agreement); and

    WHEREAS,  NSP and  WEC further  wish to  provide for  the employment  by the
Company of the Executive, and the Executive wishes to serve the Company, in  the
capacities and on the terms and conditions set forth in this Agreement;

    NOW, THEREFORE, it is hereby agreed as follows:

        1.   EMPLOYMENT PERIOD.  The Company shall employ the Executive, and the
    Executive shall serve the Company, on the terms and conditions set forth  in
    this  Agreement, for an initial period  (the "Initial Period") and a further
    period (the "Secondary Period") (the Initial Period and the Secondary Period
    are hereinafter referred to  in the aggregate  as the "Employment  Period").
    The  Initial Period  shall begin  at the Effective  Time (as  defined in the
    Merger Agreement),  and end  on the  later of  (i) the  date of  the  annual
    meeting  of shareholders of  the Company that  occurs in 1998,  and (ii) the
    last day  of the  sixteenth full  month following  the Effective  Time.  The
    Secondary Period shall begin at the end of the Initial Period and end on the
    later  of July  1, 2000 and  the second anniversary  of the last  day of the
    Initial Period.

        2.  POSITION AND DUTIES.  (a)  During the Initial Period, the  Executive
    shall  serve  as Chairman  of the  Board  of Directors  of the  Company (the
    "Board") and  Chief  Executive  Officer  of  the  Company,  and  during  the
    Secondary  Period, the  Executive shall serve  as Chairman of  the Board, in
    each  case  as  an  employee  of  the  Company  and  with  such  duties  and
    responsibilities  as are  customarily assigned  to such  positions, and such
    other duties and  responsibilities not  inconsistent therewith  as may  from
    time  to time  be assigned  to him by  the Board.  The Executive  shall be a
    member of the Board on the first day of the Employment Period, and the Board
    shall propose  the Executive  for re-election  to the  Board throughout  the
    Employment Period.

        (b)  During the Initial Period: (i) as is customary, the Chief Operating
    Officer of the  Company shall  report to the  Executive in  his capacity  as
    Chief  Executive Officer; (ii)  the subsidiary of  the Company that provides
    administrative  and  other  services   to  the  Company's  utility   company
    subsidiaries  (the "Service Company"),  as well as  the Company's subsidiary
    NRG Energy, Inc.  ("NRG"), and  their respective  chief executive  officers,
    shall  report to  the Executive; and  (iii) the subsidiaries  of the Company
    (other than the Service Company and  NRG) that are operating companies,  and
    their  respective  chief  executive  officers,  shall  report  to  the Chief
    Operating Officer of the Company.

        (c) During the Employment Period, and excluding any periods of  vacation
    and  sick  leave to  which the  Executive is  entitled, the  Executive shall
    devote reasonable attention  and time  during normal business  hours to  the
    business  and  affairs  of  the  Company and,  to  the  extent  necessary to
    discharge  the  responsibilities  assigned  to  the  Executive  under   this
    Agreement,  use the  Executive's reasonable best  efforts to  carry out such
    responsibilities faithfully and efficiently. It shall

                                      D-1
<PAGE>
    not be considered a violation of the foregoing for the Executive to serve on
    corporate, industry, civic or  charitable boards or  committees, so long  as
    such  activities do not significantly interfere  with the performance of the
    Executive's responsibilities as  an employee  of the  Company in  accordance
    with this Agreement.

        (d)  The  Executive's  services  shall  be  performed  primarily  at the
    Company's headquarters in Minneapolis, Minnesota.

        3.   COMPENSATION.   (a)   BASE SALARY.   The  Executive's  compensation
    during  the  Employment Period  shall be  determined by  the Board  upon the
    recommendation of the Compensation  Committee of the  Board, subject to  the
    next  sentence and Section 3(b). During the Employment Period, the Executive
    shall receive an annual base salary ("Annual Base Salary") of not less  than
    his  annual  base  salary  from  NSP as  in  effect  immediately  before the
    Effective Time. The Annual Base Salary  shall be payable in accordance  with
    the  Company's regular  payroll practice  for its  senior executives,  as in
    effect from time  to time.  During the  Employment Period,  the Annual  Base
    Salary  shall  be  reviewed for  possible  increase at  least  annually. Any
    increase in  the Annual  Base Salary  shall not  limit or  reduce any  other
    obligation of the Company under this Agreement. The Annual Base Salary shall
    not  be reduced after any  such increase, and the  term "Annual Base Salary"
    shall thereafter refer to the Annual Base Salary as so increased.

        (b)    INCENTIVE  COMPENSATION.    During  the  Employment  Period,  the
    Executive  shall participate in short-term  incentive compensation plans and
    long-term incentive  compensation  plans (the  latter  to consist  of  plans
    offering  stock  options,  restricted stock  and  other  long-term incentive
    compensation) providing him with the opportunity to earn, on a  year-by-year
    basis,  short-term  and  long-term  incentive  compensation  (the "Incentive
    Compensation") at least equal to the amounts that he had the opportunity  to
    earn  under the comparable plans of NSP  as in effect immediately before the
    Effective Time.

        (c)    OTHER   BENEFITS.    (i)     SUPPLEMENTAL  EXECUTIVE   RETIREMENT
    PLAN.   During the  Employment Period, the Executive  shall participate in a
    supplemental executive  retirement plan  ("SERP")  such that  the  aggregate
    value  of the retirement benefits that he and his spouse will receive at the
    end of the Employment Period under all defined benefit plans of the  Company
    and  its affiliates  (whether qualified  or not) will  be not  less than the
    aggregate value of  the benefits he  would have received  had he  continued,
    through  the  end  of  the Employment  Period,  to  accrue  the supplemental
    retirement benefits provided by the  terms of his employment agreement  with
    NSP  as in effect immediately before  the Effective Time, and to participate
    in the NSP Deferred Compensation Plan, the NSP Excess Benefit Plan, and  the
    NSP  Pension Plan, all  as in effect immediately  before the Effective Time;
    PROVIDED, that  notwithstanding the  terms of  the foregoing  agreement  and
    plans,  in determining  benefits under  the SERP,  benefits pursuant  to the
    foregoing plans shall be computed as if they were based upon the Executive's
    average  compensation  for  the  three   consecutive  years  in  which   his
    compensation  was  the  highest.  In  addition,  the  SERP  shall  offer the
    Executive the option to receive his benefits thereunder in a single lump sum
    payment on terms and conditions no less favorable than those in effect  with
    respect to the supplemental retirement benefits of Richard A. Abdoo pursuant
    to  the  letter agreement  dated  November 21,  1994  regarding supplemental
    benefits from WEC to Richard A. Abdoo or otherwise, as in effect immediately
    before the Effective Time; provided, that such lump sum payment option shall
    be subject to the consent of the  Board in its sole discretion. Finally,  if
    the  Executive dies while  employed, or deemed pursuant  to paragraph (a) of
    Section 5 to be employed,  by the Company, his  surviving spouse (or, if  he
    has  no surviving spouse,  his estate) shall  be entitled to  receive a SERP
    benefit equal in  value to the  SERP benefit that  the Executive would  have
    received  under the SERP if he had retired (rather than died) on the date of
    his death and received a lump sum  SERP benefit; PROVIDED, that in the  case
    where  the Executive has  no surviving spouse, the  benefit pursuant to this
    sentence shall be paid  in a lump  sum; and PROVIDED,  further, that in  the
    case  where the  Executive has a  surviving spouse, the  benefit pursuant to
    this sentence shall be  paid in the  form of a single  life annuity for  her
    life   unless   she   elects   a   single   lump   sum   payment   and   the

                                      D-2
<PAGE>
    Board, in its sole discretion, consents to the lump sum payment. The Company
    shall maintain and fund one or  more grantor trusts (the "Trusts"), or  such
    other funding mechanism as may be satisfactory to the Executive, which shall
    comply  with the following sentence and which shall at all times be adequate
    to provide for the payment of all  benefits under the SERP to the  Executive
    and  his spouse, as well as any elective deferrals of Annual Cash Incentives
    by the  Executive (with  such adequacy  being determined  by an  independent
    consulting firm acceptable to the Executive, whose fees shall be paid by the
    Company).  The assets of the Trusts (if  any) shall be subject to the claims
    of the  Company's creditors,  and the  Trusts (if  any) shall  in all  other
    respects  be designed  to prevent  the Executive  and his  spouse from being
    taxed on the assets  or income thereof,  except as and  when such assets  or
    income are paid to them.

           (ii)  During  the Employment  Period, the  Company shall  provide the
       Executive with life  insurance coverage (the  "Life Insurance  Coverage")
       providing  a death  benefit to such  beneficiary or  beneficiaries as the
       Executive may designate  of not  less than  three times  his Annual  Base
       Salary.  Following the Employment  Period, the Company  shall provide the
       Executive with a  life insurance benefit  at least equal  to the  benefit
       that  would  have been  provided to  the  Executive after  termination of
       employment under  the  Northern  States Power  Company  Officer  Survivor
       Benefit Plan as in effect immediately before the Effective Time.

          (iii)  In  addition,  and  without  limiting  the  generality  of  the
       foregoing, during the Employment Period and thereafter: (A) the Executive
       shall be entitled to participate in all applicable incentive, savings and
       retirement plans, practices, policies and programs of the Company to  the
       same  extent as  other senior  executives (or,  where applicable, retired
       senior executives)  of the  Company;  and (B)  the Executive  and/or  the
       Executive's   family,  as  the  case  may   be,  shall  be  eligible  for
       participation in, and  shall receive all  benefits under, all  applicable
       welfare  benefit plans, practices, policies  and programs provided by the
       Company, other than severance plans, practices, policies and programs but
       including, without limitation, medical, prescription, dental, disability,
       salary  continuance,  employee  life  insurance,  group  life  insurance,
       accidental death and travel accident insurance plans and programs, to the
       same  extent as  other senior  executives (or,  where applicable, retired
       senior executives) of the Company.

        (d)  FRINGE BENEFITS.  During the Employment Period, the Executive shall
    be entitled to receive fringe benefits  on the same terms and conditions  as
    he  received such fringe benefits from  NSP immediately before the Effective
    Time or, if more  favorable, the terms and  conditions that fringe  benefits
    were available to Richard A. Abdoo from WEC immediately before the Effective
    Time.

        4.    TERMINATION  OF  EMPLOYMENT.   (a)    DEATH  OR  DISABILITY.   The
    Executive's employment shall  terminate automatically  upon the  Executive's
    death  during  the  Employment  Period. The  Company  shall  be  entitled to
    terminate the Executive's employment  because of the Executive's  Disability
    during  the Employment Period. "Disability" means that (i) the Executive has
    been unable, for a period of  180 consecutive business days, to perform  the
    Executive's  duties under this Agreement, as  a result of physical or mental
    illness or  injury, and  (ii) a  physician selected  by the  Company or  its
    insurers,   and  acceptable  to  the  Executive  or  the  Executive's  legal
    representative, has determined that the Executive's incapacity is total  and
    permanent.  A termination of  the Executive's employment  by the Company for
    Disability shall be  communicated to  the Executive by  written notice,  and
    shall  be effective  on the  30th day  after receipt  of such  notice by the
    Executive (the "Disability Effective Date"), unless the Executive returns to
    full-time performance  of  the  Executive's  duties  before  the  Disability
    Effective Date.

        (b)   BY THE  COMPANY.  (i)   The Company  may terminate the Executive's
    employment during the Employment Period for Cause or without Cause.  "Cause"
    means:

               A.     the  willful  and   continued  failure  of  the  Executive
           substantially to perform the Executive's duties under this  Agreement
           (other  than as  a result of  physical or mental  illness or injury),
           after the Board of  the Company delivers to  the Executive a  written

                                      D-3
<PAGE>
           demand  for substantial performance  that specifically identifies the
           manner in  which  the  Board  believes that  the  Executive  has  not
           substantially performed the Executive's duties; or

               B.   illegal  conduct or  gross misconduct  by the  Executive, in
           either case that is willful and results in material and  demonstrable
           damage to the business or reputation of the Company.

    No  act or failure to  act on the part of  the Executive shall be considered
    "willful" unless it is done, or omitted to be done, by the Executive in  bad
    faith  or without reasonable belief that  the Executive's action or omission
    was in the best interests of the Company. Any act or failure to act that  is
    based  upon authority  given pursuant  to a  resolution duly  adopted by the
    Board, or  the advice  of counsel  for the  Company, shall  be  conclusively
    presumed  to be done, or omitted to be  done, by the Executive in good faith
    and in the best interests of the Company.

           (ii) A termination of the  Executive's employment for Cause shall  be
       effected  in accordance with the  following procedures. The Company shall
       give the Executive written notice ("Notice of Termination for Cause")  of
       its  intention to terminate the Executive's employment for Cause, setting
       forth in reasonable detail the specific conduct of the Executive that  it
       considers  to  constitute Cause  and  the specific  provision(s)  of this
       Agreement on which it relies, and stating the date, time and place of the
       Special Board Meeting for  Cause. The "Special  Board Meeting for  Cause"
       means a meeting of the Board called and held specifically for the purpose
       of  considering the Executive's  termination for Cause,  that takes place
       not less  than ten  and not  more  than twenty  business days  after  the
       Executive  receives the  Notice of  Termination for  Cause. The Executive
       shall be given an opportunity, together with counsel, to be heard at  the
       Special  Board Meeting for  Cause. The Executive's  termination for Cause
       shall be  effective when  and if  a  resolution is  duly adopted  at  the
       Special  Board Meeting for Cause by affirmative vote of a majority of the
       entire membership  of the  Board, excluding  employee directors,  stating
       that  in the good faith opinion of  the Board, the Executive is guilty of
       the conduct described in  the Notice of Termination  for Cause, and  that
       conduct constitutes Cause under this Agreement.

          (iii)  A termination of the Executive's employment without Cause shall
       be effected  in accordance  with the  following procedures.  The  Company
       shall  give the Executive written  notice ("Notice of Termination without
       Cause") of its intention to terminate the Executive's employment  without
       Cause,  stating the  date, time  and place  of the  Special Board Meeting
       without Cause. The "Special Board Meeting without Cause" means a  meeting
       of  the Board called and held specifically for the purpose of considering
       the Executive's termination without Cause, that takes place not less than
       ten and not more than twenty  business days after the Executive  receives
       the  Notice of Termination without Cause. The Executive shall be given an
       opportunity, together  with counsel,  to be  heard at  the Special  Board
       Meeting without Cause. The Executive's termination without Cause shall be
       effective  when and if a resolution is  duly adopted at the Special Board
       Meeting without Cause  by affirmative vote  of a majority  of the  entire
       membership  of the Board, excluding  employee directors, stating that the
       Executive is terminated without Cause.

        (c)  GOOD REASON.  (i)  The Executive may terminate employment for  Good
    Reason or without Good Reason. "Good Reason" means:

               A.  the assignment to the Executive of any duties inconsistent in
           any respect with paragraph (a) of Section 2 of this Agreement, or any
           other  action  by the  Company that  results in  a diminution  in the
           Executive's position,  authority, duties  or responsibilities,  other
           than  an isolated, insubstantial  and inadvertent action  that is not
           taken in bad  faith and  is remedied  by the  Company promptly  after
           receipt of notice thereof from the Executive;

                                      D-4
<PAGE>
               B.   any failure by  the Company to comply  with any provision of
           Section 3 of  this Agreement, other  than an isolated,  insubstantial
           and  inadvertent  failure  that is  not  taken  in bad  faith  and is
           remedied by the Company promptly after receipt of notice thereof from
           the Executive;

               C.  any requirement by the Company that the Executive's  services
           be  rendered primarily  at a  location or  locations other  than that
           provided for in paragraph (d) of Section 2 of this Agreement;

               D.  any  purported termination of  the Executive's employment  by
           the  Company for a reason  or in a manner  not expressly permitted by
           this Agreement;

               E.  any failure  by the Company to  comply with paragraph (c)  of
           Section 11 of this Agreement; or

               F.  any other substantial breach of this Agreement by the Company
           that  either is  not taken in  good faith  or is not  remedied by the
           Company promptly after receipt of notice thereof from the Executive.

           (ii) A termination  of employment  by the Executive  for Good  Reason
       shall  be effectuated  by giving the  Company written  notice ("Notice of
       Termination for  Good  Reason")  of the  termination,  setting  forth  in
       reasonable  detail the specific  conduct of the  Company that constitutes
       Good Reason and the specific provision(s) of this Agreement on which  the
       Executive  relies. A termination of employment  by the Executive for Good
       Reason shall be effective  on the fifth business  day following the  date
       when  the  Notice of  Termination for  Good Reason  is given,  unless the
       notice sets forth a  later date (which  date shall in  no event be  later
       than 30 days after the notice is given).

          (iii)  A termination  of the  Executive's employment  by the Executive
       without Good  Reason shall  be  effected by  giving the  Company  written
       notice of the termination.

        (d)   NO WAIVER.  The failure to set forth any fact or circumstance in a
    Notice of Termination for Cause, a Notice of Termination without Cause or  a
    Notice  of Termination for Good Reason shall  not constitute a waiver of the
    right to  assert,  and shall  not  preclude  the party  giving  notice  from
    asserting,  such fact  or circumstance  in an  attempt to  enforce any right
    under or provision of this Agreement.

        (e)  DATE OF TERMINATION.  The  "Date of Termination" means the date  of
    the  Executive's death, the Disability Effective Date, the date on which the
    termination of  the  Executive's employment  by  the Company  for  Cause  or
    without  Cause or by the Executive for Good Reason is effective, or the date
    on which  the  Executive  gives  the Company  notice  of  a  termination  of
    employment without Good Reason, as the case may be.

        5.  OBLIGATIONS OF THE COMPANY UPON TERMINATION.

        (a)  BY THE COMPANY OTHER THAN FOR CAUSE OR DISABILITY; BY THE EXECUTIVE
    FOR  GOOD REASON. If,  during the Employment  Period, the Company terminates
    the Executive's  employment, other  than  for Cause  or Disability,  or  the
    Executive  terminates employment for Good Reason, the Company shall continue
    to provide the  Executive with the  compensation and benefits  set forth  in
    paragraphs  (a), (b) and (c) of Section 3  as if he had remained employed by
    the Company pursuant  to this Agreement  through the end  of the  Employment
    Period and then retire (at which time he will be treated as eligible for all
    retiree  welfare  benefits and  other  benefits provided  to  retired senior
    executives, as set forth in Section 3(c)(ii) and (iii)); PROVIDED, that  the
    Incentive  Compensation  for  such  period shall  be  equal  to  the maximum
    Incentive Compensation that the Executive  would have been eligible to  earn
    for  such  period;  PROVIDED,  further,  that  in  lieu  of  stock  options,
    restricted stock and other stock-based  awards, the Executive shall be  paid
    cash  equal to the fair market value (without regard to any restrictions) of
    the stock options, restricted stock and other stock-based awards that  would
    otherwise   have  been  granted;  PROVIDED,  further,  that  to  the  extent

                                      D-5
<PAGE>
    any benefits described  in paragraph  (c) of  Section 3  cannot be  provided
    pursuant  to  the  plan  or  program  maintained  by  the  Company  for  its
    executives, the Company  shall provide  such benefits outside  such plan  or
    program at no additional cost (including without limitation tax cost) to the
    Executive and his family; and PROVIDED, finally, that during any period when
    the  Executive  is eligible  to receive  benefits of  the type  described in
    clause  (B)   of   paragraph   (c)(iii)   of   Section   3   under   another
    employer-provided  plan,  the benefits  provided by  the Company  under this
    paragraph (a) of  Section 5 may  be made secondary  to those provided  under
    such  other  plan.  In  addition  to  the  foregoing,  any  restricted stock
    outstanding on the Date of Termination shall be fully vested as of the  Date
    of  Termination and all options outstanding on the Date of Termination shall
    be fully vested and exercisable and  shall remain in effect and  exercisable
    through the end of their respective terms, without regard to the termination
    of  the Executive's employment. The  payments and benefits provided pursuant
    to this paragraph (a) of Section 5 are intended as liquidated damages for  a
    termination  of the  Executive's employment  by the  Company other  than for
    Cause or  Disability  or  for  the  actions of  the  Company  leading  to  a
    termination  of the Executive's employment by the Executive for Good Reason,
    and shall be the sole and exclusive remedy therefor.

        (b)  DEATH OR DISABILITY.   If the Executive's employment is  terminated
    by  reason  of the  Executive's death  or  Disability during  the Employment
    Period, the  Company shall  pay to  the Executive  or, in  the case  of  the
    Executive's death, to the Executive's designated beneficiaries (or, if there
    is  no such beneficiary, to the Executive's estate or legal representative),
    in a lump sum in cash within 30 days after the Date of Termination, the  sum
    of the following amounts (the "Accrued Obligations"): (1) any portion of the
    Executive's  Annual Base Salary through the Date of Termination that has not
    yet been paid; (2) an amount representing the Incentive Compensation for the
    period that includes the Date of Termination, computed by assuming that  the
    amount  of all  such Incentive  Compensation would  be equal  to the maximum
    amount of such  Incentive Compensation  that the Executive  would have  been
    eligible to earn for such period, and multiplying that amount by a fraction,
    the numerator of which is the number of days in such period through the Date
    of  Termination, and the denominator of which is the total number of days in
    the relevant  period;  (3)  any  compensation  previously  deferred  by  the
    Executive  (together with any accrued interest or earnings thereon) that has
    not yet been paid; and (4) any accrued but unpaid Incentive Compensation and
    vacation pay; and the Company shall  have no further obligations under  this
    Agreement, except as specified in Section 6 below.

        (c)   BY  THE COMPANY FOR  CAUSE; BY  THE EXECUTIVE OTHER  THAN FOR GOOD
    REASON.  If  the Executive's  employment is  terminated by  the Company  for
    Cause  during the Employment Period, the Company shall pay the Executive the
    Annual Base Salary  through the Date  of Termination and  the amount of  any
    compensation previously deferred by the Executive (together with any accrued
    interest  or earnings thereon), in each case to the extent not yet paid, and
    the Company shall have no  further obligations under this Agreement,  except
    as  specified in  Section 6 below.  If the  Executive voluntarily terminates
    employment during the  Employment Period,  other than for  Good Reason,  the
    Company  shall pay the Accrued Obligations to the Executive in a lump sum in
    cash within 30 days of the Date  of Termination, and the Company shall  have
    no  further obligations under this Agreement, except as specified in Section
    6 below.

        6.  NON-EXCLUSIVITY OF RIGHTS.  Nothing in this Agreement shall  prevent
    or  limit the  Executive's continuing or  future participation  in any plan,
    program, policy or practice provided by the Company or any of its affiliated
    companies for which the Executive may qualify, nor, subject to paragraph (f)
    of Section 12, shall  anything in this Agreement  limit or otherwise  affect
    such  rights as the Executive may have  under any contract or agreement with
    the Company or any  of its affiliated companies.  Vested benefits and  other
    amounts  that  the  Executive is  otherwise  entitled to  receive  under the
    Incentive Compensation, the SERP, the Life Insurance Coverage, or any  other
    plan, policy, practice or program of, or any contract or agreement with, the
    Company or any

                                      D-6
<PAGE>
    of  its affiliated companies  on or after  the Date of  Termination shall be
    payable in accordance with  the terms of each  such plan, policy,  practice,
    program,  contract or  agreement, as the  case may be,  except as explicitly
    modified by this Agreement.

        7.  FULL  SETTLEMENT.   The Company's  obligation to  make the  payments
    provided  for  in,  and otherwise  to  perform its  obligations  under, this
    Agreement shall not  be affected by  any set-off, counterclaim,  recoupment,
    defense  or other claim, right  or action that the  Company may have against
    the Executive or  others. In no  event shall the  Executive be obligated  to
    seek  other employment or take any other  action by way of mitigation of the
    amounts payable  to  the Executive  under  any  of the  provisions  of  this
    Agreement and, except as specifically provided in paragraph (a) of Section 5
    with  respect to benefits  described in clause (B)  of paragraph (c)(iii) of
    Section 3, such  amounts shall  not be  reduced, regardless  of whether  the
    Executive obtains other employment.

        8.   CONFIDENTIAL INFORMATION.  The  Executive shall hold in a fiduciary
    capacity  for  the  benefit  of  the  Company  all  secret  or  confidential
    information,  knowledge  or  data relating  to  the  Company or  any  of its
    affiliated companies  and their  respective  businesses that  the  Executive
    obtains  during  the Executive's  employment by  the Company  or any  of its
    affiliated companies  and that  is not  public knowledge  (other than  as  a
    result  of  the  Executive's  violation of  this  Section  8) ("Confidential
    Information"). The Executive shall  not communicate, divulge or  disseminate
    Confidential  Information  at  any  time  during  or  after  the Executive's
    employment with the Company,  except with the prior  written consent of  the
    Company  or as otherwise required by law or legal process. In no event shall
    any asserted violation  of the  provisions of  this Section  8 constitute  a
    basis  for deferring  or withholding  any amounts  otherwise payable  to the
    Executive under this Agreement.

        9.  CERTAIN ADDITIONAL PAYMENTS BY THE  COMPANY.  (a)  Anything in  this
    Agreement  to  the  contrary  notwithstanding,  in  the  event  it  shall be
    determined that any  payment or distribution  by the Company  to or for  the
    benefit  of  the  Executive  (whether  paid  or  payable  or  distributed or
    distributable pursuant  to the  terms of  this Agreement  or otherwise,  but
    determined  without regard  to any  additional payments  required under this
    Section 9)  (a "Payment")  would be  subject to  the excise  tax imposed  by
    Section  4999 of the Internal Revenue Code  of 1986, as amended (the "Code")
    or any interest or penalties are  incurred by the Executive with respect  to
    such  excise  tax (such  excise  tax, together  with  any such  interest and
    penalties, are hereinafter  collectively referred to  as the "Excise  Tax"),
    then  the Executive  shall be entitled  to receive an  additional payment (a
    "Gross-Up Payment") in an amount such that after payment by the Executive of
    all taxes (including any interest or penalties imposed with respect to  such
    taxes),  including, without limitation,  any income taxes  (and any interest
    and penalties imposed with respect thereto) and Excise Tax imposed upon  the
    Gross-Up  Payment, the Executive  retains an amount  of the Gross-Up Payment
    equal to the Excise Tax imposed upon the Payments.

        (b) Subject to the  provisions of paragraph (c)  of this Section 9,  all
    determinations  required to be made under  this Section 9, including whether
    and when a  Gross-Up Payment  is required and  the amount  of such  Gross-Up
    Payment   and  the   assumptions  to  be   utilized  in   arriving  at  such
    determination,  shall  be  made  by  a  certified  public  accounting   firm
    designated  by the  Executive (the  "Accounting Firm"),  which shall provide
    detailed supporting  calculations  both to  the  Company and  the  Executive
    within  15 business days  of the receipt  of notice from  the Executive that
    there has  been a  Payment, or  such earlier  time as  is requested  by  the
    Company.  In the event that the Accounting  Firm is serving as accountant or
    auditor for the individual, entity or group effecting the change of control,
    the Executive shall appoint another nationally recognized accounting firm to
    make the determinations required hereunder (which accounting firm shall then
    be referred to as the Accounting  Firm hereunder). All fees and expenses  of
    the  Accounting  Firm shall  be borne  solely by  the Company.  Any Gross-Up
    Payment, as determined  pursuant to  this Section 9,  shall be  paid by  the
    Company  to the Executive within five days  of the receipt of the Accounting
    Firm's determination.  Any determination  by the  Accounting Firm  shall  be
    binding

                                      D-7
<PAGE>
    upon  the Company and the  Executive. As a result  of the uncertainty in the
    application of  Section  4999  of  the  Code at  the  time  of  the  initial
    determination by the Accounting Firm hereunder, it is possible that Gross-Up
    Payments  which will not have been made by the Company should have been made
    ("Underpayment"), consistent  with  the  calculations required  to  be  made
    hereunder.  In the event that the  Company exhausts its remedies pursuant to
    paragraph (c) of this Section 9 and the Executive thereafter is required  to
    make  a payment of any  Excise Tax, the Accounting  Firm shall determine the
    amount of the Underpayment that has occurred and any such Underpayment shall
    be promptly paid by the Company to or for the benefit of the Executive.

        (c) The Executive shall  notify the Company in  writing of any claim  by
    the  Internal Revenue Service that, if successful, would require the payment
    by the Company of the Gross-Up Payment. Such notification shall be given  as
    soon  as practicable but no later than ten business days after the Executive
    is informed in writing of  such claim and shall  apprise the Company of  the
    nature  of such claim  and the date on  which such claim  is requested to be
    paid. The Executive shall not pay such claim prior to the expiration of  the
    30-day  period  following the  date on  which  it gives  such notice  to the
    Company (or such shorter period ending on the date that any payment of taxes
    with respect to such claim is due). If the Company notifies the Executive in
    writing prior to the  expiration of such period  that it desires to  contest
    such claim, the Executive shall:

           (i)  give  the Company  any information  reasonably requested  by the
       Company relating to such claim,

           (ii) take such action in connection with contesting such claim as the
       Company shall reasonably request in writing from time to time, including,
       without limitation, accepting legal  representation with respect to  such
       claim by an attorney reasonably selected by the Company,

          (iii) cooperate with the Company in good faith in order effectively to
       contest such claim, and

          (iv)  permit the Company to participate in any proceedings relating to
       such claim;

    PROVIDED, however, that the  Company shall bear and  pay directly all  costs
    and  expenses  (including  additional interest  and  penalties)  incurred in
    connection with  such contest  and shall  indemnify and  hold the  Executive
    harmless, on an after-tax basis, for any Excise Tax or income tax (including
    interest  and penalties  with respect thereto)  imposed as a  result of such
    representation and payment of costs and expenses. Without limitation on  the
    foregoing  provisions of this paragraph (c)  of Section 9, the Company shall
    control all proceedings taken  in connection with such  contest and, at  its
    sole  option,  may  pursue or  forego  any and  all  administrative appeals,
    proceedings, hearings and conferences with  the taxing authority in  respect
    of  such claim and may,  at its sole option,  either direct the Executive to
    pay the  tax claimed  and sue  for  a refund  or contest  the claim  in  any
    permissible  manner, and the Executive agrees to prosecute such contest to a
    determination before  any administrative  tribunal, in  a court  of  initial
    jurisdiction  and  in one  or more  appellate courts,  as the  Company shall
    determine; PROVIDED, however, that if  the Company directs the Executive  to
    pay such claim and sue for a refund, the Company shall advance the amount of
    such payment to the Executive, on an interest-free basis and shall indemnify
    and  hold the Executive harmless, on an after-tax basis, from any Excise Tax
    or income tax (including interest or penalties with respect thereto) imposed
    with respect to  such advance  or with respect  to any  imputed income  with
    respect  to such advance;  and PROVIDED, further, that  any extension of the
    statute of limitations relating to payment of taxes for the taxable year  of
    the  Executive with respect to which such  contested amount is claimed to be
    due is limited solely to  such contested amount. Furthermore, the  Company's
    control  of the contest shall  be limited to issues  with respect to which a
    Gross-Up Payment  would be  payable  hereunder and  the Executive  shall  be
    entitled to settle or contest, as the case may be, any other issue raised by
    the Internal Revenue Service or any other taxing authority.

                                      D-8
<PAGE>
        (d)  If, after the receipt by the Executive of an amount advanced by the
    Company pursuant to paragraph (c) of  this Section 9, the Executive  becomes
    entitled  to receive  any refund with  respect to such  claim, the Executive
    shall (subject to the Company's complying with the requirements of paragraph
    (c) of this Section 9) promptly pay to the Company the amount of such refund
    (together with any interest paid or credited thereon after taxes  applicable
    thereto).  If, after the receipt  by the Executive of  an amount advanced by
    the Company pursuant to paragraph (c) of this Section 9, a determination  is
    made  that the Executive shall not be entitled to any refund with respect to
    such claim and the Company does not  notify the Executive in writing of  its
    intent  to contest such denial of refund  prior to the expiration of 30 days
    after such determination, then such advance shall be forgiven and shall  not
    be required to be repaid and the amount of such advance shall offset, to the
    extent thereof, the amount of Gross-Up Payment required to be paid.

        10.   ATTORNEYS' FEES.   The Company agrees to  pay, as incurred, to the
    fullest extent  permitted by  law,  all legal  fees  and expenses  that  the
    Executive may reasonably incur as a result of any contest (regardless of the
    outcome)  by  the  Company,  the  Executive or  others  of  the  validity or
    enforceability of or liability under, or otherwise involving, any  provision
    of  this Agreement,  together with  interest on  any delayed  payment at the
    applicable federal rate provided for in Section 7872(f)(2)(A) of the Code.

        11.  SUCCESSORS.  (a)  This Agreement is personal to the Executive  and,
    without the prior written consent of the Company, shall not be assignable by
    the   Executive  otherwise  than  by  will   or  the  laws  of  descent  and
    distribution.  This  Agreement  shall  inure  to  the  benefit  of  and   be
    enforceable by the Executive's legal representatives.

        (b) This Agreement shall inure to the benefit of and be binding upon the
    Company and its successors and assigns.

        (c) The Company shall require any successor (whether direct or indirect,
    by purchase, merger, consolidation or otherwise) to all or substantially all
    of  the business and/or assets of the  Company expressly to assume and agree
    to perform this Agreement in the same manner and to the same extent that the
    Company would have  been required to  perform it if  no such succession  had
    taken  place.  As used  in  this Agreement,  "Company"  shall mean  both the
    Company as defined above and any  such successor that assumes and agrees  to
    perform this Agreement, by operation of law or otherwise.

        12.   MISCELLANEOUS.   (a)   This  Agreement shall  be governed  by, and
    construed in accordance with,  the laws of the  State of Minnesota,  without
    reference  to principles of conflict of laws. The captions of this Agreement
    are not part of  the provisions hereof  and shall have  no force or  effect.
    This  Agreement may not be amended or modified except by a written agreement
    executed by  the parties  hereto or  their respective  successors and  legal
    representatives.

        (b)  All notices and other communications  under this Agreement shall be
    in writing and  shall be given  by hand delivery  to the other  party or  by
    registered  or certified  mail, return  receipt requested,  postage prepaid,
    addressed as follows:

                If to the Executive:

                If to the Company:

                    Attention: General Counsel

                                      D-9
<PAGE>
    or to such other address as either  party furnishes to the other in  writing
    in   accordance  with  this  paragraph  (b)   of  Section  12.  Notices  and
    communications shall be effective when actually received by the addressee.

        (c)  The  invalidity  or  unenforceability  of  any  provision  of  this
    Agreement  shall  not affect  the validity  or  enforceability of  any other
    provision of this  Agreement. If any  provision of this  Agreement shall  be
    held  invalid  or  unenforceable  in part,  the  remaining  portion  of such
    provision, together  with  all other  provisions  of this  Agreement,  shall
    remain  valid and enforceable and  continue in full force  and effect to the
    fullest extent consistent with law.

        (d) Notwithstanding any other provision  of this Agreement, the  Company
    may  withhold from amounts payable under  this Agreement all federal, state,
    local and foreign taxes that are required to be withheld by applicable  laws
    or regulations.

        (e)  The  Executive's or  the Company's  failure  to insist  upon strict
    compliance with  any  provision of,  or  to  assert any  right  under,  this
    Agreement  (including,  without limitation,  the right  of the  Executive to
    terminate employment for Good Reason pursuant to paragraph (c) of Section  4
    of  this Agreement) shall not be deemed to  be a waiver of such provision or
    right or of any other provision of or right under this Agreement.

        (f) The  Executive  and  the Company  acknowledge  that  this  Agreement
    supersedes  any other agreement  between them concerning  the subject matter
    hereof.

        (g) The rights and  benefits of the Executive  under this Agreement  may
    not   be  anticipated,   assigned,  alienated  or   subject  to  attachment,
    garnishment, levy, execution or other  legal or equitable process except  as
    required  by  law. Any  attempt by  the  Executive to  anticipate, alienate,
    assign, sell, transfer, pledge, encumber or  charge the same shall be  void.
    Payments  hereunder shall not  be considered assets of  the Executive in the
    event of insolvency or bankruptcy.

        (h) This  Agreement may  be executed  in several  counterparts, each  of
    which  shall be deemed  an original, and  said counterparts shall constitute
    but one and the same instrument.

    IN WITNESS WHEREOF, the Executive has hereunto set the Executive's hand and,
pursuant to the authorization of its Board of Directors, the Company has  caused
this  Agreement to be executed in its name on  its behalf, all as of the day and
year first above written.

                              EMPLOYMENT AGREEMENT

    THIS  AGREEMENT by and between Primergy Corporation, a Wisconsin corporation
(the "Company"), and Richard A. Abdoo (the "Executive"), dated as of the     day
of          , 199 .

                          W I T N E S S E T H  T H A T

    WHEREAS, Northern States Power Company, a Minnesota corporation ("NSP")  and
Wisconsin  Energy Corporation, a Wisconsin corporation ("WEC") have entered into
an Amended and Restated Agreement and Plan of Merger dated as of April 28, 1995,
as amended and restated  as of July 26,  1995 (the "Merger Agreement"),  whereby
the  NSP and  WEC organizations  will merge, with  the Company  as the surviving
parent; and

    WHEREAS, NSP  and  WEC  wish  to  provide  for  the  orderly  succession  of
management of the Company following the Effective Time (as defined in the Merger
Agreement); and

    WHEREAS,  NSP and  WEC further  wish to  provide for  the employment  by the
Company of the Executive, and the Executive wishes to serve the Company, in  the
capacities and on the terms and conditions set forth in this Agreement;

    NOW, THEREFORE, it is hereby agreed as follows:

        1.   EMPLOYMENT PERIOD.  The Company shall employ the Executive, and the
    Executive shall serve the Company, on the terms and conditions set forth  in
    this  Agreement, for an initial period  (the "Initial Period") and a further
    period (the "Secondary Period") (the Initial Period and the Secondary Period
    are hereinafter referred to  in the aggregate  as the "Employment  Period").
    The  Initial Period  shall begin  at the Effective  Time (as  defined in the
    Merger Agreement), and  end on the  earlier of:  (i) such date  as James  J.
    Howard  ceases to be Chief Executive Officer  of the Company for any reason;
    or (ii) the later of (a) the  date of the annual meeting of shareholders  of
    the  Company that occurs in 1998, and (b) the last day of the sixteenth full
    month following the Effective Time. The Secondary Period shall begin at  the
    end  of the Initial Period and  end on that date which  is the later of: (x)
    January 31, 2002; or (y) five (5)  years after the first day of the  Initial
    Period;  except that  on the  third, fourth  and fifth  anniversaries of the
    first day of the Employment Period,  the Secondary Period shall be  extended
    by  one year unless either party gives written notice to the other, at least
    60 days before the Secondary Period would otherwise be so extended, that the
    Secondary Period shall not be so extended.

        2.  POSITION AND DUTIES.  (a)  During the Initial Period, the  Executive
    shall  serve as Vice Chairman of the  Board of Directors of the Company (the
    "Board"), President and Chief Operating  Officer of the Company; during  the
    Secondary  Period, the Executive shall serve  as Vice Chairman of the Board,
    President and Chief Executive Officer of  the Company; and on and after  any
    date  during the Employment Period as of  which James J. Howard ceases to be
    Chairman of the  Board, the  Executive shall serve  as the  Chairman of  the
    Board; in each case with such duties and responsibilities as are customarily
    assigned  to such positions, and such  other duties and responsibilities not
    inconsistent therewith as may from  time to time be  assigned to him by  the
    Board.  The Executive shall be a member of the Board on the first day of the
    Employment Period, and the Board shall propose the Executive for re-election
    to the Board throughout the Employment Period.

        (b) During the Initial Period: (i) as is customary, the Executive  shall
    report to the Chief Executive Officer of the Company; (ii) the subsidiary of
    the Company that provides administrative and other services to the Company's
    utility  company  subsidiaries  (the  "Service  Company"),  as  well  as the
    Company's subsidiary NRG  Energy Inc.  ("NRG"), and  their respective  chief
    executive  officers,  shall report  to the  Chief  Executive Officer  of the
    Company; and (iii)  all other subsidiaries  of the Company  (other than  the
    Service  Company and  NRG), and  their respective  chief executive officers,
    shall report to the Executive.

                                      E-1
<PAGE>
        (c) During the Employment Period, and excluding any periods of  vacation
    and  sick  leave to  which the  Executive is  entitled, the  Executive shall
    devote reasonable attention  and time  during normal business  hours to  the
    business  and  affairs  of  the  Company and,  to  the  extent  necessary to
    discharge  the  responsibilities  assigned  to  the  Executive  under   this
    Agreement,  use the  Executive's reasonable best  efforts to  carry out such
    responsibilities faithfully and  efficiently. It shall  not be considered  a
    violation  of  the  foregoing  for  the  Executive  to  serve  on corporate,
    industry, civic  or  charitable  boards  or  committees,  so  long  as  such
    activities  do  not  significantly  interfere with  the  performance  of the
    Executive's responsibilities as  an employee  of the  Company in  accordance
    with this Agreement.

        (d)   The  Company's  headquarters  shall  be  located  in  Minneapolis,
    Minnesota and the  Executive shall reside  in the general  area of the  Twin
    Cities of Minneapolis and St. Paul, Minnesota. The Company shall assure that
    the Executive suffers no financial loss on the sale of Executive's Milwaukee
    residence  (including the value of loss of  tax deferrals which may occur if
    Executive does  not  reinvest  all of  the  proceeds  of the  sale  of  such
    residence  in accordance with the provisions of Section 1034 of the Internal
    Revenue Code of 1986, as amended  and a gross-up payment for the  additional
    income  taxes payable  by the  Executive as a  result of  such payment). The
    Company shall  reimburse  the  Executive  for all  of  his  moving  expenses
    incurred in relocating Executive's residence to the Twin Cities area. During
    the  period from the first day of  the Employment Period through the earlier
    of the  end  of the  last  day  of the  sixth  full calendar  month  of  the
    Employment Period and the date of such relocation, the Company shall provide
    the  Executive with an apartment  in the Twin Cities  area and reimburse him
    for reasonable expenses while in the Twin Cities area and travel between the
    Twin Cities area and his principal residence, provided in each case that the
    Executive complies  with  the  policies, practices  and  procedures  of  the
    Company   for   submission  of   expense   reports,  receipts,   or  similar
    documentation of such expenses.

        3.   COMPENSATION.   (a)   BASE SALARY.   The  Executive's  compensation
    during  the  Employment Period  shall be  determined by  the Board  upon the
    recommendation of the Compensation  Committee of the  Board, subject to  the
    next  sentence and Section 3(b). During the Employment Period, the Executive
    shall receive an annual base salary ("Annual Base Salary") of not less  than
    his  annual  base  salary  from  WEC as  in  effect  immediately  before the
    Effective Time. The Annual Base Salary  shall be payable in accordance  with
    the  Company's regular  payroll practice  for its  senior executives,  as in
    effect from time  to time.  During the  Employment Period,  the Annual  Base
    Salary  shall  be  reviewed for  possible  increase at  least  annually. Any
    increase in  the Annual  Base Salary  shall not  limit or  reduce any  other
    obligation of the Company under this Agreement. The Annual Base Salary shall
    not  be reduced after any  such increase, and the  term "Annual Base Salary"
    shall thereafter refer to the Annual Base Salary as so increased.

        (b) INCENTIVE COMPENSATION.  During the Employment Period, the Executive
    shall participate in short-term  incentive compensation plans and  long-term
    incentive  compensation plans (the latter to consist of plans offering stock
    options,  restricted  stock  and  other  long-term  incentive  compensation)
    providing  him  with  the  opportunity to  earn,  on  a  year-by-year basis,
    short-term   and   long-term   incentive   compensation   (the    "Incentive
    Compensation")  at least equal to the amounts that he had the opportunity to
    earn under the comparable plans of  WEC as in effect immediately before  the
    Effective Time.

        (c)   OTHER   BENEFITS.     (i)     SUPPLEMENTAL   EXECUTIVE  RETIREMENT
    PLAN.  During the  Employment Period, the Executive  shall participate in  a
    supplemental  executive  retirement plan  ("SERP")  such that  the aggregate
    value of the retirement benefits that he and his spouse will receive at  the
    end  of the Employment Period under all defined benefit plans of the Company
    and its affiliates  (whether qualified  or not) will  be not  less than  the
    benefits  he would have  received had he  continued, through the  end of the
    Employment Period, to participate in  the WEC Defined Benefit Pension  Plan,
    Supplemental  Executive Retirement Plan A, Supplemental Executive Retirement
    Plan B, the special supplemental benefits letter dated November 21, 1994  as
    amended  on  April 26,  1995 between  WEC and  the Executive,  and Executive
    Deferred Compensation Plan

                                      E-2
<PAGE>
    (collectively, the  "WEC  Plans"),  as  in  effect  immediately  before  the
    Effective  Time. The  Company shall  maintain and  fund one  or more grantor
    trusts (the "Trusts"), the assets of which shall at all times be adequate to
    provide for the payment of all benefits under the SERP to the Executive  and
    his  spouse, as well as any  elective deferrals of Incentive Compensation by
    the Executive  (with  such  adequacy  being  determined  by  an  independent
    consulting firm acceptable to the Executive, whose fees shall be paid by the
    Company).  The assets of  the Trusts shall  be subject to  the claims of the
    Company's creditors, and the Trusts shall in all other respects be  designed
    to  prevent the Executive and  his spouse from being  taxed on the assets or
    income thereof, except as and when such assets or income are paid to them.

           (ii) During  the Employment  Period, the  Company shall  provide  the
       Executive  with life  insurance coverage (the  "Life Insurance Coverage")
       providing a death  benefit to  such beneficiary or  beneficiaries as  the
       Executive  may designate  of not  less than  three times  his Annual Base
       Salary.

          (iii)  In  addition,  and  without  limiting  the  generality  of  the
       foregoing, during the Employment Period and thereafter: (A) the Executive
       shall be entitled to participate in all applicable incentive, savings and
       retirement  plans, practices, policies and programs of the Company to the
       same extent as  other senior  executives (or,  where applicable,  retired
       senior  executives)  of the  Company, and  (B)  the Executive  and/or the
       Executive's  family,  as  the  case   may  be,  shall  be  eligible   for
       participation  in, and shall  receive all benefits  under, all applicable
       welfare benefit plans, practices, policies  and programs provided by  the
       Company, other than severance plans, practices, policies and programs but
       including, without limitation, medical, prescription, dental, disability,
       salary  continuance,  employee  life  insurance,  group  life  insurance,
       accidental death and travel accident insurance plans and programs, to the
       same extent as  other senior  executives (or,  where applicable,  retired
       senior executives) of the Company.

        (d)  FRINGE BENEFITS.  During the Employment Period, the Executive shall
    be entitled to receive fringe benefits  on the same terms and conditions  as
    he  received such fringe benefits from  WEC immediately before the Effective
    Time.

        4.   TERMINATION  OF  EMPLOYMENT.    (a)   DEATH  OR  DISABILITY.    The
    Executive's  employment shall  terminate automatically  upon the Executive's
    death during  the  Employment  Period.  The Company  shall  be  entitled  to
    terminate  the Executive's employment because  of the Executive's Disability
    during the Employment Period. "Disability" means that (i) the Executive  has
    been  unable, for a period of 180  consecutive business days, to perform the
    Executive's duties under this Agreement, as  a result of physical or  mental
    illness  or injury,  and (ii)  a physician  selected by  the Company  or its
    insurers,  and  acceptable  to  the  Executive  or  the  Executive's   legal
    representative,  has determined that the Executive's incapacity is total and
    permanent. A termination of  the Executive's employment  by the Company  for
    Disability  shall be  communicated to the  Executive by  written notice, and
    shall be effective  on the  30th day  after receipt  of such  notice by  the
    Executive (the "Disability Effective Date"), unless the Executive returns to
    full-time  performance  of  the  Executive's  duties  before  the Disability
    Effective Date.

        (b) BY THE  COMPANY.   (i)  The  Company may  terminate the  Executive's
    employment  during the Employment Period for Cause or without Cause. "Cause"
    means:

               A.  the willful and continued failure of Executive  substantially
           to perform the Executive's duties under this Agreement (other than as
           a result of physical or mental illness or injury), after the Board of
           the   Company  delivers  to  the   Executive  a  written  demand  for
           substantial performance that  specifically identifies  the manner  in
           which  the Board  believes that  the Executive  has not substantially
           performed the Executive's duties; or

                                      E-3
<PAGE>
               B.   illegal conduct  or gross  misconduct by  the Executive,  in
           either  case that is willful and results in material and demonstrable
           damage to the business or reputation of the Company.

    No act or failure to  act on the part of  the Executive shall be  considered
    "willful"  unless it is done, or omitted to be done, by the Executive in bad
    faith or without reasonable belief  that the Executive's action or  omission
    was  in the best interests of the Company. Any act or failure to act that is
    based upon authority  given pursuant  to a  resolution duly  adopted by  the
    Board,  or  the advice  of counsel  for the  Company, shall  be conclusively
    presumed to be done, or omitted to  be done, by the Executive in good  faith
    and in the best interests of the Company.

           (ii)  A termination of the Executive's  employment for Cause shall be
       effected in accordance with the  following procedures. The Company  shall
       give  the Executive written notice ("Notice of Termination for Cause") of
       its intention to terminate the Executive's employment for Cause,  setting
       forth  in reasonable detail the specific conduct of the Executive that it
       considers to  constitute  Cause and  the  specific provision(s)  of  this
       Agreement on which it relies, and stating the date, time and place of the
       Special  Board Meeting for  Cause. The "Special  Board Meeting for Cause"
       means a meeting of the Board called and held specifically for the purpose
       of considering the  Executive's termination for  Cause, that takes  place
       not  less  than ten  and not  more  than twenty  business days  after the
       Executive receives the  Notice of  Termination for  Cause. The  Executive
       shall  be given an opportunity, together with counsel, to be heard at the
       Special Board Meeting  for Cause. The  Executive's termination for  Cause
       shall  be  effective when  and if  a  resolution is  duly adopted  at the
       Special Board Meeting for Cause by affirmative vote of a majority of  the
       entire  membership of  the Board,  excluding employee  directors, stating
       that in the good faith opinion of  the Board, the Executive is guilty  of
       the  conduct described in  the Notice of Termination  for Cause, and that
       conduct constitutes Cause under this Agreement.

          (iii) A termination of the Executive's employment without Cause  shall
       be  effected  in accordance  with the  following procedures.  The Company
       shall give the Executive written  notice ("Notice of Termination  without
       Cause")  of its intention to terminate the Executive's employment without
       Cause, stating the  date, time  and place  of the  Special Board  Meeting
       without  Cause. The "Special Board Meeting without Cause" means a meeting
       of the Board called and held specifically for the purpose of  considering
       the Executive's termination without Cause, that takes place not less than
       ten  and not more than twenty  business days after the Executive receives
       the Notice of Termination without Cause. The Executive shall be given  an
       opportunity,  together with  counsel, to  be heard  at the  Special Board
       Meeting without Cause. The Executive's termination without Cause shall be
       effective when and if a resolution  is duly adopted at the Special  Board
       Meeting  without Cause  by affirmative vote  of a majority  of the entire
       membership of the Board, excluding  employee directors, stating that  the
       Executive is terminated without Cause.

        (c)  GOOD REASON.  (i)  The  Executive may terminate employment for Good
    Reason or without Good Reason. "Good Reason" means:

               A.  the assignment to the Executive of any duties inconsistent in
           any respect with paragraph (a) of Section 2 of this Agreement, or any
           other action  by the  Company that  results in  a diminution  in  the
           Executive's  position, authority,  duties or  responsibilities, other
           than an isolated,  insubstantial and inadvertent  action that is  not
           taken  in bad  faith and  is remedied  by the  Company promptly after
           receipt of notice thereof from the Executive;

               B.  any failure  by the Company to  comply with any provision  of
           Section  3 of this  Agreement, other than  an isolated, insubstantial
           and inadvertent  failure  that is  not  taken  in bad  faith  and  is
           remedied by the Company promptly after receipt of notice thereof from
           the Executive;

                                      E-4
<PAGE>
               C.   any requirement by the Company that the Executive's services
           be rendered  primarily at  a location  or locations  other than  that
           provided for in paragraph (d) of Section 2 of this Agreement;

               D.   any purported  termination of the  Executive's employment by
           the Company for a  reason or in a  manner not expressly permitted  by
           this Agreement;

               E.   any failure by  the Company to comply  with paragraph (c) of
           Section 11 of this Agreement; or

               F.  any other substantial breach of this Agreement by the Company
           that either is  not taken in  good faith  or is not  remedied by  the
           Company promptly after receipt of notice thereof from the Executive.

           (ii)  A termination  of employment by  the Executive  for Good Reason
       shall be effectuated  by giving  the Company written  notice ("Notice  of
       Termination  for  Good  Reason")  of the  termination,  setting  forth in
       reasonable detail the  specific conduct of  the Company that  constitutes
       Good  Reason and the specific provision(s) of this Agreement on which the
       Executive relies. A termination of  employment by the Executive for  Good
       Reason  shall be effective  on the fifth business  day following the date
       when the  Notice of  Termination for  Good Reason  is given,  unless  the
       notice  sets forth a  later date (which  date shall in  no event be later
       than 30 days after the notice is given).

          (iii) A termination  of the  Executive's employment  by the  Executive
       without  Good  Reason shall  be effected  by  giving the  Company written
       notice of the termination.

        (d) NO WAIVER.  The failure to  set forth any fact or circumstance in  a
    Notice  of Termination for Cause, a Notice of Termination without Cause or a
    Notice of Termination for Good Reason  shall not constitute a waiver of  the
    right  to  assert,  and shall  not  preclude  the party  giving  notice from
    asserting, such fact  or circumstance  in an  attempt to  enforce any  right
    under or provision of this Agreement.

        (e)  DATE OF TERMINATION.   The "Date of Termination"  means the date of
    the Executive's death, the Disability Effective Date, the date on which  the
    termination  of  the  Executive's employment  by  the Company  for  Cause or
    without Cause or by the Executive for Good Reason is effective, or the  date
    on  which  the  Executive  gives  the Company  notice  of  a  termination of
    employment without Good Reason, as the case may be.

        5.  OBLIGATIONS  OF THE COMPANY  UPON TERMINATION.   (a) OTHER THAN  FOR
    CAUSE,  DEATH OR DISABILITY; GOOD REASON.  If, during the Employment Period,
    the Company terminates the Executive's  employment, other than for Cause  or
    Disability,  or  the Executive  terminates employment  for Good  Reason, the
    Company shall continue to  provide the Executive  with the compensation  and
    benefits  set forth in paragraphs (a), (b) and (c) of Section 3 as if he had
    remained employed by the Company pursuant to this Agreement through the  end
    of  the Employment Period and then retired [at which time he will be treated
    as eligible for all retiree welfare benefits and other benefits provided  to
    retired  senior executives,  as set  forth in  Section 3(c)(iii)]; provided,
    that the  Incentive Compensation  for  such period  shall  be equal  to  the
    maximum  Incentive Compensation that the  Executive would have been eligible
    to earn for such  period; provided, further that  in lieu of stock  options,
    restricted  stock and other stock-based awards,  the Executive shall be paid
    cash equal to the fair market value (without regard to any restrictions)  of
    the  stock options, restricted stock and other stock-based awards that would
    otherwise have been granted; and provided,  further, that to the extent  any
    benefits described in paragraph (c) of Section 3 cannot be provided pursuant
    to  the plan or  program maintained by  the Company for  its executives, the
    Company shall  provide such  benefits outside  such plan  or program  at  no
    additional cost (including without limitation tax cost) to the Executive and
    his family; and provided, finally, that during any period when the Executive
    is  eligible to  receive benefits  of the  type described  in clause  (B) of
    paragraph (c)(iii) of  Section 3 under  another employer-provided plan,  the
    benefits provided by the Company

                                      E-5
<PAGE>
    under  this  paragraph (a)  of  Section 5  may  be made  secondary  to those
    provided under such other plan. In addition to the foregoing, any restricted
    stock outstanding on the Date of Termination shall be fully vested as of the
    Date of Termination and all options  outstanding on the Date of  Termination
    shall  be  fully  vested and  exercisable  and  shall remain  in  effect and
    exercisable through the end of their respective terms, without regard to the
    termination  of  the  Executive's  employment.  The  payments  and  benefits
    provided  pursuant  to  this paragraph  (a)  of  Section 5  are  intended as
    liquidated damages for a  termination of the  Executive's employment by  the
    Company other than for Cause or Disability or for the actions of the Company
    leading  to a termination of the Executive's employment by the Executive for
    Good Reason, and shall be the sole and exclusive remedy therefor.

        (b) DEATH AND DISABILITY.   If the Executive's employment is  terminated
    by  reason  of the  Executive's death  or  Disability during  the Employment
    Period, the  Company shall  pay to  the Executive  or, in  the case  of  the
    Executive's death, to the Executive's designated beneficiaries (or, if there
    is  no such beneficiary, to the Executive's estate or legal representative),
    in a lump sum in cash within 30 days after the Date of Termination, the  sum
    of the following amounts (the "Accrued Obligations"): (1) any portion of the
    Executive's  Annual Base Salary through the Date of Termination that has not
    yet been paid; (2) an amount representing the Incentive Compensation for the
    period that includes the Date of Termination, computed by assuming that  the
    amount  of all  such Incentive  Compensation would  be equal  to the maximum
    amount of such  Incentive Compensation  that the Executive  would have  been
    eligible to earn for such period, and multiplying that amount by a fraction,
    the numerator of which is the number of days in such period through the Date
    of  Termination, and the denominator of which is the total number of days in
    the relevant  period;  (3)  any  compensation  previously  deferred  by  the
    Executive  (together with any accrued interest or earnings thereon) that has
    not yet been paid; and (4) any accrued but unpaid Incentive Compensation and
    vacation pay; and the Company shall  have no further obligations under  this
    Agreement, except as specified in Section 6 below.

        (c)  BY THE  COMPANY FOR  CAUSE; BY  THE EXECUTIVE  OTHER THAN  FOR GOOD
    REASON.  If  the Executive's  employment is  terminated by  the Company  for
    Cause  during the Employment Period, the Company shall pay the Executive the
    Annual Base Salary  through the Date  of Termination and  the amount of  any
    compensation previously deferred by the Executive (together with any accrued
    interest  or earnings thereon), in each case to the extent not yet paid, and
    the Company shall have no  further obligations under this Agreement,  except
    as  specified in  Section 6 below.  If the  Executive voluntarily terminates
    employment during the  Employment Period,  other than for  Good Reason,  the
    Company  shall pay the Accrued Obligations to the Executive in a lump sum in
    cash within 30 days of the Date  of Termination, and the Company shall  have
    no  further obligations under this Agreement, except as specified in Section
    6 below.

        6.  NON-EXCLUSIVITY OF RIGHTS.  Nothing in this Agreement shall  prevent
    or  limit the  Executive's continuing or  future participation  in any plan,
    program, policy or practice provided by the Company or any of its affiliated
    companies for which the Executive may qualify, nor, subject to paragraph (f)
    of Section 12, shall  anything in this Agreement  limit or otherwise  affect
    such  rights as the Executive may have  under any contract or agreement with
    the Company or any  of its affiliated companies.  Vested benefits and  other
    amounts  that  the  Executive is  otherwise  entitled to  receive  under the
    Incentive Compensation, the SERP, the Life Insurance Coverage, or any  other
    plan, policy, practice or program of, or any contract or agreement with, the
    Company  or  any  of  its  affiliated companies  on  or  after  the  Date of
    Termination shall be payable in accordance with the terms of each such plan,
    policy, practice, program, contract or agreement, as the case may be, except
    as explicitly modified by this Agreement.

        7.  FULL  SETTLEMENT.   The Company's  obligation to  make the  payments
    provided  for  in,  and otherwise  to  perform its  obligations  under, this
    Agreement shall not  be affected by  any set-off, counterclaim,  recoupment,
    defense  or other claim, right  or action that the  Company may have against
    the Executive or  others. In no  event shall the  Executive be obligated  to
    seek other

                                      E-6
<PAGE>
    employment  or take  any other  action by way  of mitigation  of the amounts
    payable to the Executive under any of the provisions of this Agreement  and,
    except  as specifically provided in paragraph  (a) of Section 5 with respect
    to benefits described in clause (B) of paragraph (c)(iii) of Section 3, such
    amounts shall not be  reduced, regardless of  whether the Executive  obtains
    other employment.

        8.   CONFIDENTIAL INFORMATION.  The  Executive shall hold in a fiduciary
    capacity  for  the  benefit  of  the  Company  all  secret  or  confidential
    information,  knowledge  or  data relating  to  the  Company or  any  of its
    affiliated companies  and their  respective  businesses that  the  Executive
    obtains  during  the Executive's  employment by  the Company  or any  of its
    affiliated companies  and that  is not  public knowledge  (other than  as  a
    result  of  the  Executive's  violation of  this  Section  8) ("Confidential
    Information"). The Executive shall  not communicate, divulge or  disseminate
    Confidential  Information  at  any  time  during  or  after  the Executive's
    employment with the Company,  except with the prior  written consent of  the
    Company  or as otherwise required by law or legal process. In no event shall
    any asserted violation  of the  provisions of  this Section  8 constitute  a
    basis  for deferring  or withholding  any amounts  otherwise payable  to the
    Executive under this Agreement.

        9.  CERTAIN ADDITIONAL  PAYMENTS BY THE COMPANY.   (a) Anything in  this
    Agreement  to  the  contrary  notwithstanding,  in  the  event  it  shall be
    determined that any  payment or distribution  by the Company  to or for  the
    benefit  of  the  Executive  (whether  paid  or  payable  or  distributed or
    distributable pursuant  to the  terms of  this Agreement  or otherwise,  but
    determined  without regard  to any  additional payments  required under this
    Section 9)  (a "Payment")  would be  subject to  the excise  tax imposed  by
    Section  4999 of the Internal Revenue Code  of 1986, as amended (the "Code")
    or any interest or penalties are  incurred by the Executive with respect  to
    such  excise  tax (such  excise  tax, together  with  any such  interest and
    penalties, are hereinafter  collectively referred to  as the "Excise  Tax"),
    then  the Executive  shall be entitled  to receive an  additional payment (a
    "Gross-Up Payment") in an amount such that after payment by the Executive of
    all taxes (including any interest or penalties imposed with respect to  such
    taxes),  including, without limitation,  any income taxes  (and any interest
    and penalties imposed with respect thereto) and Excise Tax imposed upon  the
    Gross-Up  Payment, the Executive  retains an amount  of the Gross-Up Payment
    equal to the Excise Tax imposed upon the Payments.

        (b) Subject to the  provisions of paragraph (c)  of this Section 9,  all
    determinations  required to be made under  this Section 9, including whether
    and when a  Gross-Up Payment  is required and  the amount  of such  Gross-Up
    Payment   and  the   assumptions  to  be   utilized  in   arriving  at  such
    determination,  shall  be  made  by  a  certified  public  accounting   firm
    designated  by the  Executive (the  "Accounting Firm"),  which shall provide
    detailed supporting  calculations  both to  the  Company and  the  Executive
    within  15 business days  of the receipt  of notice from  the Executive that
    there has  been a  Payment, or  such earlier  time as  is requested  by  the
    Company.  In the event that the Accounting  Firm is serving as accountant or
    auditor for the individual, entity or group effecting the change of control,
    the Executive shall appoint another nationally recognized accounting firm to
    make the determinations required hereunder (which accounting firm shall then
    be referred to as the Accounting  Firm hereunder). All fees and expenses  of
    the  Accounting  Firm shall  be borne  solely by  the Company.  Any Gross-Up
    Payment, as determined  pursuant to  this Section 9,  shall be  paid by  the
    Company  to the Executive within five days  of the receipt of the Accounting
    Firm's determination.  Any determination  by the  Accounting Firm  shall  be
    binding  upon the Company and the Executive.  As a result of the uncertainty
    in the application of Section  4999 of the Code at  the time of the  initial
    determination by the Accounting Firm hereunder, it is possible that Gross-Up
    Payments  which will not have been made by the Company should have been made
    ("Underpayment"), consistent  with  the  calculations required  to  be  made
    hereunder.  In the event that the  Company exhausts its remedies pursuant to
    paragraph (c) of this

                                      E-7
<PAGE>
    Section 9 and the Executive thereafter is required to make a payment of  any
    Excise   Tax,  the  Accounting  Firm  shall  determine  the  amount  of  the
    Underpayment that has occurred and  any such Underpayment shall be  promptly
    paid by the Company to or for the benefit of the Executive.

        (c)  The Executive shall notify  the Company in writing  of any claim by
    the Internal Revenue Service that, if successful, would require the  payment
    by  the Company of the Gross-Up Payment. Such notification shall be given as
    soon as practicable but no later than ten business days after the  Executive
    is  informed in writing of  such claim and shall  apprise the Company of the
    nature of such claim  and the date  on which such claim  is requested to  be
    paid.  The Executive shall not pay such claim prior to the expiration of the
    30-day period  following the  date on  which  it gives  such notice  to  the
    Company (or such shorter period ending on the date that any payment of taxes
    with respect to such claim is due). If the Company notifies the Executive in
    writing  prior to the expiration  of such period that  it desires to contest
    such claim, the Executive shall:

           (i) give  the Company  any information  reasonably requested  by  the
       Company relating to such claim,

           (ii) take such action in connection with contesting such claim as the
       Company shall reasonably request in writing from time to time, including,
       without  limitation, accepting legal representation  with respect to such
       claim by an attorney reasonably selected by the Company,

          (iii) cooperate with the Company in good faith in order effectively to
       contest such claim, and

          (iv) permit the Company to participate in any proceedings relating  to
       such claim;

    PROVIDED,  however, that the  Company shall bear and  pay directly all costs
    and expenses  (including  additional  interest and  penalties)  incurred  in
    connection  with such  contest and  shall indemnify  and hold  the Executive
    harmless, on an after-tax basis, for any Excise Tax or income tax (including
    interest and penalties  with respect thereto)  imposed as a  result of  such
    representation  and payment of costs and expenses. Without limitation on the
    foregoing provisions of this paragraph (c)  of Section 9, the Company  shall
    control  all proceedings taken  in connection with such  contest and, at its
    sole option,  may  pursue or  forego  any and  all  administrative  appeals,
    proceedings,  hearings and conferences with  the taxing authority in respect
    of such claim and may,  at its sole option,  either direct the Executive  to
    pay  the  tax claimed  and sue  for a  refund  or contest  the claim  in any
    permissible manner, and the Executive agrees to prosecute such contest to  a
    determination  before  any administrative  tribunal, in  a court  of initial
    jurisdiction and  in one  or more  appellate courts,  as the  Company  shall
    determine;  PROVIDED, however, that if the  Company directs the Executive to
    pay such claim and sue for a refund, the Company shall advance the amount of
    such payment to the Executive, on an interest-free basis and shall indemnify
    and hold the Executive harmless, on an after-tax basis, from any Excise  Tax
    or income tax (including interest or penalties with respect thereto) imposed
    with  respect to  such advance  or with respect  to any  imputed income with
    respect to such advance;  and PROVIDED, further, that  any extension of  the
    statute  of limitations relating to payment of taxes for the taxable year of
    the Executive with respect to which  such contested amount is claimed to  be
    due  is limited solely to such  contested amount. Furthermore, the Company's
    control of the contest shall  be limited to issues  with respect to which  a
    Gross-Up  Payment  would be  payable hereunder  and  the Executive  shall be
    entitled to settle or contest, as the case may be, any other issue raised by
    the Internal Revenue Service or any other taxing authority.

        (d) If, after the receipt by the Executive of an amount advanced by  the
    Company  pursuant to paragraph (c) of  this Section 9, the Executive becomes
    entitled to receive  any refund with  respect to such  claim, the  Executive
    shall (subject to the Company's complying with the requirements of paragraph
    (c) of this Section 9) promptly pay to the Company the amount of such refund
    (together  with any interest paid or credited thereon after taxes applicable
    thereto). If after the receipt by

                                      E-8
<PAGE>
    the Executive of an amount advanced by the Company pursuant to paragraph (c)
    of this Section 9, a determination is  made that the Executive shall not  be
    entitled  to any refund with respect to  such claim and the Company does not
    notify the Executive  in writing  of its intent  to contest  such denial  of
    refund  prior to  the expiration of  30 days after  such determination, then
    such advance shall be forgiven  and shall not be  required to be repaid  and
    the  amount of such advance shall offset,  to the extent thereof, the amount
    of Gross-Up Payment required to be paid.

        10.  ATTORNEYS' FEES.   The Company agrees to  pay, as incurred, to  the
    fullest  extent  permitted by  law,  all legal  fees  and expenses  that the
    Executive may reasonably incur as a result of any contest (regardless of the
    outcome) by  the  Company,  the  Executive or  others  of  the  validity  or
    enforceability  of or liability under, or otherwise involving, any provision
    of this Agreement,  together with  interest on  any delayed  payment at  the
    applicable federal rate provided for in Section 7872(f)(2)(A) of the Code.

        11.   SUCCESSORS.  (a)  This Agreement is personal to the Executive and,
    without the prior written consent of the Company, shall not be assignable by
    the  Executive  otherwise  than  by  will   or  the  laws  of  descent   and
    distribution.   This  Agreement  shall  inure  to  the  benefit  of  and  be
    enforceable by the Executive's legal representatives.

        (b) This Agreement shall inure to the benefit of and be binding upon the
    Company and its successors and assigns.

        (c) The Company shall require any successor (whether direct or indirect,
    by purchase, merger, consolidation or otherwise) to all or substantially all
    of the business and/or assets of  the Company expressly to assume and  agree
    to perform this Agreement in the same manner and to the same extent that the
    Company  would have been  required to perform  it if no  such succession had
    taken place.  As used  in  this Agreement,  "Company"  shall mean  both  the
    Company  as defined above and any such  successor that assumes and agrees to
    perform this Agreement, by operation of law or otherwise.

        12.   MISCELLANEOUS.   (a)  This Agreement  shall  be governed  by,  and
    construed  in accordance with,  the laws of the  State of Minnesota, without
    reference to principles of conflict of laws. The captions of this  Agreement
    are  not part of  the provisions hereof  and shall have  no force or effect.
    This Agreement may not be amended or modified except by a written  agreement
    executed  by the  parties hereto  or their  respective successors  and legal
    representatives.

        (b) All notices and other  communications under this Agreement shall  be
    in  writing and  shall be given  by hand delivery  to the other  party or by
    registered or  certified mail,  return receipt  requested, postage  prepaid,
    addressed as follows:

                If to the Executive:

                If to the Company:

    or  to such other address as either  party furnishes to the other in writing
    in  accordance  with  this  paragraph   (b)  of  Section  12.  Notices   and
    communications shall be effective when actually received by the addressee.

        (c)  The  invalidity  or  unenforceability  of  any  provision  of  this
    Agreement shall  not affect  the  validity or  enforceability of  any  other
    provision  of this  Agreement. If any  provision of this  Agreement shall be
    held invalid  or  unenforceable  in  part, the  remaining  portion  of  such
    provision,  together  with all  other  provisions of  this  Agreement, shall
    remain valid and enforceable  and continue in full  force and effect to  the
    fullest extent consistent with law.

    Agreement (including,  without limitation,  the right  of the  Executive  to
    terminate  employment for Good Reason pursuant to paragraph (c) of Section 4

    right or of any other provision of or right under this Agreement.

        (f)  The  Executive  and  the Company  acknowledge  that  this Agreement
    supersedes any other  agreement between them  concerning the subject  matter
    hereof.

        (g)  The rights and  benefits of the Executive  under this Agreement may
    not  be  anticipated,   assigned,  alienated  or   subject  to   attachment,
    garnishment,  levy, execution or other legal  or equitable process except as
    required by  law. Any  attempt  by the  Executive to  anticipate,  alienate,
    assign,  sell, transfer, pledge, encumber or  charge the same shall be void.
    Payments hereunder shall not  be considered assets of  the Executive in  the
    event of insolvency or bankruptcy.

        (h)  This Agreement  may be  executed in  several counterparts,  each of
    which shall be deemed  an original, and  said counterparts shall  constitute
    but one and the same instrument.

pursuant  to the authorization of its Board of Directors, the Company has caused
this Agreement to be executed in its name  on its behalf, all as of the day  and
year first above written.

Board of Directors
Northern States Power Company
414 Nicollet Mall
Minneapolis, MN 55401

Gentlemen and Mesdames:

    You  have requested  our opinion as  to the  fairness to the  holders of the
outstanding shares of Common Stock, par value $2.50 per share (the "Shares"), of
Northern States Power  Company (the "Company")  of the exchange  ratio of  1.626
shares  of Common Stock, par value $.01  per share, of Primergy Corporation (the
"Primergy Common Stock") to  be received for each  Share (the "Exchange  Ratio")
pursuant  to the Amended and Restated Agreement  and Plan of Merger, dated as of
April 28, 1995, as amended  and restated as of July  26, 1995, by and among  the
Company,  Wisconsin  Energy  Corporation  ("Wisconsin  Energy"),  Northern Power
Wisconsin Corp., a wholly owned subsidiary of the Company, and WEC Sub Corp.,  a
wholly owned subsidiary of Wisconsin Energy (the "Agreement"). Capitalized terms
used  herein but not defined  shall have the meanings  ascribed to such terms in
the Agreement.

    Goldman, Sachs & Co.  ("Goldman Sachs"), as part  of its investment  banking
business,  is  continually  engaged in  the  valuation of  businesses  and their
securities   in   connection   with   mergers   and   acquisitions,   negotiated
underwritings,  competitive  biddings,  secondary  distributions  of  listed and
unlisted securities, private placements and valuations for estate, corporate and
other purposes.  We  are  familiar  with the  Company  having  provided  certain
investment  banking services to the Company  from time to time, including acting
as managing underwriter of  certain public offerings of  debt securities of  the
Company,  and  having acted  as its  financial advisor  in connection  with, and
having participated in certain of the negotiations leading to, the Agreement. We
also have provided certain investment banking services to Wisconsin Energy  from
time  to  time,  including  acting as  managing  underwriter  of  certain public
offerings of debt securities of Wisconsin Electric Power Company, a wholly owned
subsidiary of Wisconsin Energy, and  may provide investment banking services  to
Wisconsin Energy in the future.

                                      F-1

    In  the ordinary course of the trading activities of Goldman Sachs, the Firm
actively trades the  debt and  equity securities  of the  Company and  Wisconsin
Energy  for its own account  and for the accounts  of customers of Goldman Sachs
and may,  therefore,  at  any  time  hold a  long  or  short  position  in  such
securities.

    In  connection with this opinion, we  have reviewed, among other things, the
Agreement; the Registration  Statement on  Form S-4, including  the Joint  Proxy
Statement/Prospectus  relating  to the  Annual  Meeting of  Shareholders  of the
Company and Special Meeting of Shareholders of Wisconsin Energy; Annual  Reports
to  shareholders and Annual  Reports on Form  10-K of the  Company and Wisconsin
Energy for the five  years ended December 31,  1994; certain interim reports  to
shareholders  and Quarterly  Reports on Form  10-Q of the  Company and Wisconsin
Energy; FERC  Forms  1  of  the Company  and  Wisconsin  Energy;  certain  other
communications  from  the  Company  and  Wisconsin  Energy  to  their respective
shareholders; and  certain internal  financial analyses  and forecasts  for  the
Company and Wisconsin Energy prepared by their respective managements, including
analyses and forecasts of certain operating efficiencies and financial synergies
(the  "Synergies") expected to be  achieved as a result  of the Mergers. We also
have held discussions with members of  the senior management of the Company  and
Wisconsin  Energy regarding the past  and current business operations, financial
condition and future prospects of their respective companies and their  analyses
of  the strategic  benefits of the  Mergers, including,  without limitation, the
amount and timing of realization of the Synergies. In addition, we have reviewed
the reported price and trading activity for the Shares and the Wisconsin  Energy
Common  Stock, compared certain  financial and stock  market information for the
Company  and  Wisconsin  Energy  with  similar  information  for  certain  other
companies  the securities of  which are publicly  traded, reviewed the financial
terms of certain recent business  combinations in the electric utility  industry
specifically  and in other industries generally and performed such other studies
and analyses as we considered appropriate.

    We have  relied  without  independent verification  upon  the  accuracy  and
completeness  of all of the  financial and other information  reviewed by us for
purposes of this opinion.  In that regard, we  have assumed, with your  consent,
that  the Synergies have been reasonably prepared on a basis reflecting the best
currently available judgments and estimates of the Company and Wisconsin  Energy
and  that  such Synergies  will  be realized  in the  amounts  and at  the times
contemplated thereby. In addition, we have not made an independent evaluation or
appraisal of the assets  and liabilities of the  Company or Wisconsin Energy  or
any  of  their  subsidiaries  and  we have  not  been  furnished  with  any such
evaluation  or  appraisal.  We  have  assumed,  with  your  consent,  that   the
consummation  of the transactions contemplated by the Agreement will be recorded
as a pooling of interests under generally accepted accounting principles. We are
not expressing any opinion herein as to the prices at which the Primergy  Common
Stock may trade if and when it is issued.

    Based upon and subject to the foregoing and based upon such other matters as
we  consider relevant, it is our opinion that as of the date hereof the Exchange
Ratio pursuant to the Agreement is fair to the holders of the Shares.

Very truly yours,

GOLDMAN, SACHS & CO.

                                                                  August 7, 1995

The Board of Directors
Wisconsin Energy Corporation
231 West Michigan Street
Milwaukee, WI 53203

Dear Members of the Board:

    We  understand that  Wisconsin Energy  Corporation, a  Wisconsin corporation
("WEC"), and Northern  States Power  Company, a  Minnesota corporation  ("NSP"),
have determined to engage in a business combination as peer firms in a merger of
equals.  In  order to  effect that  combination, NSP  has formed  Northern Power
Wisconsin Corp. ("New NSP"), a Wisconsin corporation; and WEC has formed WEC Sub
Corp. ("WEC Sub"),  a Wisconsin  corporation. The  terms and  conditions of  the
business combination are set forth in an Amended and Restated Agreement and Plan
of  Merger, dated as of April  28, 1995, as amended and  restated as of July 26,
1995 (the  "Agreement"), among  NSP, WEC,  New NSP  and WEC  Sub. The  Agreement
provides  for,  among other  things  (i) the  merger of  NSP  into New  NSP (the
"Reincorporation Merger") and  (ii) the  merger of  WEC Sub  into the  surviving
corporation  in the Reincorporation  Merger (the "NSP  Merger"). Pursuant to the
Reincorporation and NSP Mergers (i) each issued and outstanding share of  Common
Stock,  $2.50  par  value, of  NSP  (the  "NSP Common  Stock")  (other  than NSP
Dissenting Shares  and shares  cancelled pursuant  to Section  2.1(b)(i) of  the
Agreement)  shall be  converted into the  right to receive  1.626 (the "Exchange
Ratio") fully paid and nonassessable shares of Common Stock, $0.01, of WEC ("WEC
Common Stock"), and  (ii) each  issued and  outstanding share  of Common  Stock,
$0.01  par  value,  of  WEC Sub  shall  be  converted into  one  fully  paid and
nonassessable  share  of  Common  Stock,  $2.50  par  value,  of  the  surviving
corporation  in the  NSP Merger  (collectively, the  "Proposed Transaction"). In
connection with the Proposed Transaction, WEC  will change its name to  Primergy
Corporation  ("Primergy"). The terms and  conditions of the Proposed Transaction
are set forth  in more detail  in the Agreement.  Capitalized terms used  herein
without  definition have the  respective meanings assigned to  such terms in the
Agreement. In addition,  in the remainder  of this letter,  references to  "WEC"
shall  be  deemed to  include WEC's  subsidiaries (including  Wisconsin Electric
Power Company and Wisconsin Natural  Gas Company, each a Wisconsin  corporation)
and references to "NSP" shall be deemed to include NSP's subsidiaries (including
Northern States Power Company, a Wisconsin corporation).

    We  have been  requested by WEC  to render  our opinion with  respect to the
fairness, from a financial point of view, to holders of WEC Common Stock of  the
Exchange Ratio to be offered in the Proposed Transaction.

    In arriving at our opinion, we have, among other things:

    (1) Reviewed  the  Annual  Reports,  Form 10-Ks  and  the  related financial
        information for the three years in  the period ended December 31,  1994,
        and  the Form 10-Qs and the  related unaudited financial information for
        the quarterly  periods ended  March  31, 1995  and  June 30,  1995,  for
        Wisconsin  Energy  Corporation,  Wisconsin  Electric  Power  Company and
        Wisconsin Natural Gas Company;

    (2) Reviewed the  Annual  Reports,  Form 10-Ks  and  the  related  financial
        information  for the three years in  the period ended December 31, 1994,
        and the Form 10-Qs and the related unaudited

                                      G-1
<PAGE>
        financial information for the quarterly periods ended March 31, 1995 and
        June 30,  1995,  for  Northern  States  Power  Company  (Minnesota)  and
        Northern States Power Company (Wisconsin);

    (3) Reviewed   certain  other  filings  with  the  Securities  and  Exchange
        Commission and  other regulatory  authorities made  by Wisconsin  Energy
        Corporation,  Wisconsin  Electric Power  Company, Wisconsin  Natural Gas
        Company, Northern States Power  Company (Minnesota) and Northern  States
        Power  Company (Wisconsin),  including proxy  statements, FERC  Form 1s,
        Form 8Ks and registration statements, during the last three years;

    (4) Reviewed certain  internal information,  including financial  forecasts,
        relating  to the  business, earnings,  capital expenditures,  cash flow,
        assets and prospects of WEC and NSP furnished to us by WEC and NSP;

    (5) Conducted discussions with members of  senior management of WEC and  NSP
        concerning   their   respective  businesses,   regulatory  environments,
        prospects   and   strategic    objectives   and   possible    operating,
        administrative  and capital  synergies which  might be  realized for the
        benefit of WEC following the Proposed Transaction;

    (6) Reviewed the historical market prices and trading activity for shares of
        WEC Common Stock and NSP Common  Stock, and compared them with those  of
        certain publicly traded companies which we deemed to be relevant;

    (7) Compared  the results of operations of WEC and NSP with those of certain
        companies which we deemed to be relevant;

    (8) Compared the proposed financial terms  of the Proposed Transaction  with
        the  financial terms  of certain utility  industry business combinations
        which we deemed to be relevant;

    (9) Analyzed the respective contributions in terms of assets, earnings, cash
        flow and shareholders' equity of WEC and NSP;

   (10) Analyzed the valuation  of shares  of WEC  Common Stock  and NSP  Common
        Stock  using  various  valuation  methodologies which  we  deemed  to be
        appropriate;

   (11) Considered the pro  forma effect  of the Proposed  Transaction on  WEC's
        capitalization, earnings and cash flow;

   (12) Compared  the  pro forma  effect of  the  Proposed Transaction  on WEC's
        capitalization ratios,  earnings per  share, dividends  per share,  book
        value  per share, cash flow per share, return on equity and payout ratio
        with each  of their  corresponding  current and  projected values  on  a
        stand-alone basis;

   (13) Considered  the obligation of  Primergy to register  as a public utility
        holding company under  the Public  Utility Holding Company  Act of  1935
        (the  "1935 Act") and  the resulting possibility  that Primergy would be
        required to dispose of WEC's and/or  NSP's gas operations or to  dispose
        of certain of WEC's and/or NSP's non-utility businesses;

   (14) Examined  the possible tax treatment of  alternative ways of effecting a
        disposition of WEC's and/or NSP's  gas operations, and a disposition  of
        certain  of WEC's  and/or NSP's  non-utility businesses  should any such
        disposition be required  pursuant to  the 1935  Act, for  which we  have
        relied on the advice of WEC's counsel;

   (15) Reviewed the Agreement, the WEC Stock Option Agreement and the NSP Stock
        Option Agreement;

   (16) Reviewed  the Joint Registration Statement of WEC and New NSP, including
        the Joint Proxy Statement/Prospectus of NSP,  WEC and New NSP dated  the
        date hereof; and

                                      G-2
<PAGE>
   (17) Reviewed  such other studies, conducted  such other analyses, considered
        such other financial, economic and market criteria, performed such other
        investigations and taken into  account such other  matters as we  deemed
        necessary or appropriate for purposes of this opinion.

    In  rendering our opinion,  we have assumed  and relied, without independent
verification, upon  the accuracy  and completeness  of all  financial and  other
information publicly available or otherwise furnished or made available to us by
WEC and NSP and have further relied upon the assurances of management of WEC and
NSP  that  they are  not aware  of any  facts that  would make  such information
inaccurate or misleading. With respect to  the financial projections of WEC  and
NSP  (including,  without  limitation,  projected  cost  savings  and  operating
synergies), we have relied upon the assurances of management of WEC and NSP that
such projections have been  reasonably prepared and  reflect the best  currently
available  estimates and judgments  of the management  of WEC and  NSP as to the
future financial performance of WEC and NSP, as  the case may be, and as to  the
outcomes  projected of legal, regulatory and other contingencies. In arriving at
our opinion, we have not made or been provided with an independent evaluation or
appraisal of the assets or liabilities (contingent or otherwise) of WEC or  NSP,
nor  have we made any physical inspection of  the properties or assets of WEC or
NSP. We have assumed that the  Proposed Transaction will be a reorganization  as
described  in Section 368(a) of  the Internal Revenue Code  of 1986, as amended,
and the regulations thereunder,  and that WEC, NSP  and the shareholders of  NSP
who  exchange their shares solely for WEC Common Stock will recognize no gain or
loss for federal  income tax purposes  as a  result of the  consummation of  the
Proposed  Transaction. We have  also assumed that  the Proposed Transaction will
qualify as a pooling  of interests for financial  accounting purposes. You  have
not  authorized us  to solicit,  and we have  not solicited,  any indications of
interest from any third party with respect to  the purchase of all or a part  of
WEC.  Our opinion herein  is necessarily based upon  financial, stock market and
other conditions and circumstances existing and  disclosed to us as of the  date
hereof.

    We  have acted as financial  advisor to WEC in  connection with the Proposed
Transaction and will  receive certain  fees for  our services.  In addition,  we

time to time for which we receive customary compensation.

    Our advisory services and the  opinion expressed herein are provided  solely

Except for its  publication in  the Joint Proxy  Statement/Prospectus dated  the
date  hereof which is being  distributed to holders of  WEC Common Stock and NSP
Common Stock  in  connection with  approval  of the  Proposed  Transaction,  our
opinion  may not be published or otherwise used or referred to without our prior
written consent. This opinion is  not intended to be  and does not constitute  a

bankers  and other factors we  deem relevant, we are of  the opinion that, as of
the date  hereof,  the Exchange  Ratio  to be  offered  in connection  with  the
Proposed  Transaction is fair, from a financial point of view, to the holders of
WEC Common Stock.

    Stock") and Fifteen Million  (15,000,000) shares of  Preferred Stock of  the
    par  value of One  Cent ($.01) per share  (hereinafter called the "Preferred

       (payable  in cash, stock or otherwise) as  may be determined by the Board
       of Directors may be declared  and paid on the  Common Stock from time  to
       time from any funds, property or shares legally available therefor.

<PAGE>
    (4)  NO PREEMPTIVE RIGHTS

       No  holder of  Common Stock  shall be  entitled as  such, as  a matter of
       right, to subscribe for  or purchase or  receive any part  of any new  or
       additional  issue of stock, or securities  convertible into stock, of any
       class whatever, whether  now or hereafter  authorized, or whether  issued
       for  cash, property or services,  by way of dividend,  or in exchange for
       the stock of another corporation.

C.  PREFERRED STOCK PROVISIONS

    The Board of Directors  shall have authority to  divide the Preferred  Stock
    into  series, to issue shares of any such series and, within the limitations
    set forth in these  Articles of Incorporation or  prescribed by law, to  fix
    and  determine  the relative  rights and  preferences of  the shares  of any
    series so  established.  Each such  series  shall  be so  designated  as  to
    distinguish  the  shares thereof  from the  shares of  all other  series and
    classes. All shares of Preferred Stock  shall be identical except as to  the
    following  relative  rights  and  preferences,  as  to  which  there  may be
    variations between different series:

           (1) The rate of dividend;

           (2) The price at and the terms and conditions on which shares may  be
       redeemed;

           (3)  The  amount payable  upon shares  in the  event of  voluntary or
       involuntary liquidation of the corporation;

           (4) Sinking fund provisions for the redemption or purchase of shares;

           (5) The terms  and conditions on  which shares may  be converted,  if
       shares are issued with the privilege of conversion;

           (6) Voting rights, if any; and

           (7) Any other rights or preferences as to which the laws of the State
       of  Wisconsin, as  in effect  at the  time of  the determination thereof,
       permit variations between different series of Preferred Stock.

    Shares of  Preferred Stock  shall  have only  such  voting rights,  if  any,
    preemptive  rights, if any, and other rights  as are fixed and determined by
    the Board of Directors in accordance with the foregoing provisions or as may
    be required by law.

D.  CERTAIN OTHER PROVISIONS AFFECTING STOCKHOLDERS

    (1)  RESTRICTION ON CERTAIN PURCHASES OF COMMON STOCK AT MARKET PREMIUM

        (a) The corporation shall not purchase  any shares of Common Stock  from
    any  person or  other entity if  more than  5% of the  outstanding shares of
    Common Stock are believed by the Board of Directors to be Beneficially Owned
    by such person or other entity at the time the purchase is authorized by the
    Board, at a  price exceeding significantly  (as determined by  the Board  of
    Directors)  the then current  market price. This  provision shall not apply,
    however, to (i) any purchase  of shares believed by  the Board to have  been
    Beneficially  Owned by the seller, or by  the seller and any of the seller's
    Affiliates consecutively, for at least  the two-year period ending with  the
    date  of purchase; (ii)  any purchase of  shares which has  been approved by
    affirmative vote by a  majority of the aggregate  number of votes which  the
    holders  of the then outstanding shares  of Common Stock and Preferred Stock
    are entitled  to  cast, voting  together  as a  class,  in the  election  of
    directors;  or (iii) any purchase pursuant to  a tender offer to all holders
    of Common Stock on the same terms.

                                      H-2
<PAGE>
        (b) As used in this Subsection (1):

           (i) "Affiliate", with respect  to any person  or other entity,  means
       any other person or other entity that directly, or indirectly through one
       or  more intermediary,  controls, is  controlled by,  or is  under common
       control with, such former person or other entity;

           (ii) "Beneficially Owned", as of  any time, means Beneficially  Owned
       within  the meaning  of Rule 13d-3  under the Securities  Exchange Act of
       1934, as in effect on June 1, 1986.

    (2)  SHARES NOT SUBJECT TO STATUTORY VOTE REDUCTION PROVISIONS

       The voting power of shares of Common Stock and Preferred Stock shall  not
       at  any time be subject to Section  180.1150 of the Wisconsin Statutes or
       any successor provision.

    (3)  BYLAW PROVISIONS FIXING GREATER VOTING REQUIREMENTS

       The Bylaws may require a greater stockholder vote than would otherwise be
       required by law or by these Articles of Incorporation for: (i) removal of
       a director  from  office;  or  (ii) amending  provisions  of  the  Bylaws
       relating  to or in connection with taking action by the unanimous consent
       of stockholders  without  a  meeting; the  number,  term,  qualification,
       classification  and election of directors; the removal of a director from
       office; notice  for  Board  of Directors'  meetings;  indemnification  of
       officers,  directors  and  other  persons by  the  corporation;  or Bylaw
       amendments. For  purposes of  Sections 180.1021  and 180.1706(4)  of  the
       Wisconsin  Statutes, each section of  the Bylaws shall be  deemed to be a
       separate bylaw.

                                  ARTICLE IV.
                              NUMBER OF DIRECTORS

    The Board of Directors shall consist of such number of directors as shall be
fixed from time to time  by or in the manner  provided in the Bylaws, which  may
provide  that the directors shall be  divided into three classes as contemplated
in Section 180.0806 of the Wisconsin Statutes or any successor provision.

                                   ARTICLE V.
                              EMERGENCY PROVISIONS

    The business and affairs of the corporation shall be managed by its Board of
Directors, except as otherwise provided in  this Article V after the  occurrence
and during the continuance of any Emergency. During any Emergency the provisions
of  this Article V shall apply to  the maximum extent permitted by the Wisconsin
Business Corporation Law, particularly  Sections 180.0207 and 180.0303  thereof,
or  any successor provisions, as  at the time in  effect. The provisions of this
Article V  shall  control during  any  Emergency, notwithstanding  any  contrary
provisions of these Articles of Incorporation or the Bylaws of the corporation.

    As  used  in this  Article V,  "Emergency" means  a catastrophic  event that
prevents a quorum of the Board of Directors from being readily assembled.

    During any Emergency, the business and  affairs of the corporation shall  be
managed  by an interim Board of Directors consisting of so many of the incumbent
directors, if any, as are known to be alive and not incapacitated, and whom  the
corporation  is able to contact by  normal means of communication, together with
provisional directors  selected as  hereinafter provided.  The total  number  of
directors  on such interim Board of Directors  shall be the lesser of the number
determined in or pursuant to the Bylaws,  or the number of eligible persons  who
are known to be alive, are not incapacitated and can be readily contacted by the
usual means of communication. The Board of Directors by resolution may from time
to  time designate a list of provisional  directors and the order of priority in
which such persons  shall become interim  directors in the  event of  Emergency,
which  designation  shall  continue in  effect  until such  resolution  has been
subsequently amended or rescinded

                                      H-3
<PAGE>
or has  by its  terms  ceased to  have effect.  Interim  directors need  not  be
stockholders  of the  corporation. In addition  to the exercise,  on a temporary
basis, of all of the powers of the regular Board of Directors, the interim Board
of Directors shall have the authority  to declare vacancies in any positions  of
the  regular  Board  of  Directors  in cases  where  any  incumbent  director is
incapacitated or missing or otherwise unable to be contacted within a reasonable
time, and to  fill such vacancies,  as well  as any vacancy  resulting from  the
death  of a director, by electing replacements to the regular Board of Directors
to serve until the next succeeding annual meeting of stockholders.

    When an Emergency has occurred,  any director or provisional director  named
in  any aforementioned resolution  is empowered on behalf  of the corporation to
declare the provisions of this Article V to be in effect, and to call a  meeting
of either the regular or an interim Board of Directors on such notice, which may
be  shorter than the notice  provided for in the  Bylaws for special meetings of
the Board of Directors,  as such person  may determine to  be advisable. In  the
case of a meeting of the interim Board of Directors, reasonable efforts shall be
made  to give such notice to all persons who  are or may be eligible to serve as
interim directors. At the first meeting of any interim Board of Directors, three
or more interim directors may act, notwithstanding any other quorum  requirement
provided  by these Articles  of Incorporation or the  Bylaws of the corporation,
and notwithstanding any failure of other interim directors to receive notice  of
the  meeting. Prior  to any  initial meeting of  the interim  Board of Directors
three or  more interim  directors,  and thereafter  a  majority of  the  interim
directors  who are deemed to be serving as such, may take action as the Board of
Directors  by  telephone  meeting,  written  instrument  or  other  means  which
reasonably  evidences the assent to  the action of a  majority of such number of
interim directors, in lieu of action at a meeting.

                                  ARTICLE VI.
                           ACQUISITION OF OWN SHARES

    Subject to the provisions of Section  D(1) of Article III of these  Articles
of  Incorporation, the corporation  is authorized to  purchase, take, receive or
otherwise acquire shares of Common Stock or Preferred Stock of the  corporation,
with the approval of the Board of Directors, with or without any vote or consent
of stockholders.

                                  ARTICLE VII.
                           AMENDMENTS TO THE ARTICLES

    Any  lawful  amendment of  these Articles  of Incorporation  may be  made by
affirmative vote by  at least the  proportion specified below  of the  aggregate
number of votes which the holders of the then outstanding shares of Common Stock
and  Preferred Stock are entitled to cast on the amendment and, if the shares of
one or more classes or series are entitled under these Articles of Incorporation
or otherwise by law  to vote thereon  as a class, affirmative  vote by the  same
proportion  of  the aggregate  number of  votes  which the  holders of  the then
outstanding shares of such one or more classes or series are entitled to cast on
the amendment. The proportion referred to above in this Article VII shall be 80%
in the case of any amendment of the provisions set forth in Sections C and  D(1)
of  Article III of these Articles of Incorporation, and in this Article VII, and
any amendment  rendering  inapplicable  to  the  corporation  Sections  180.1130
through  180.1134 of  the Wisconsin  Business Corporation  Law or  any successor
provisions, and shall be a majority in all other cases.

                                 ARTICLE VIII.
                               EFFECT OF HEADINGS

    The descriptive headings in these Articles of Incorporation were formulated,
used and inserted herein for convenience only and shall not be deemed to  affect
the meaning or construction of any of the provisions hereof.

                                  STOCKHOLDERS

    1.01.    ANNUAL MEETING.   The  annual  meeting of  the stockholders  of the
corporation shall be held  each year on  the first business day  of June, or  on
such  earlier or later date and at the time designated by or under the authority
of the Board  of Directors,  the Chairman  of the  Board, the  President or  the
Secretary, for the purpose of electing directors and for the transaction of such
other business as may properly come before the meeting.

    1.02.   SPECIAL  MEETINGS.   Special meetings  of the  stockholders, for any
purpose or  purposes,  unless otherwise  prescribed  by the  Wisconsin  Business
Corporation  Law, may be called by the Chairman of the Board, the President or a
majority of the Board of Directors. If and as required by the Wisconsin Business
Corporation  Law,  a  special  meeting  shall  be  called  upon  written  demand
describing  one or more purposes for which it is to be held by holders of shares
with at least 10% of the votes entitled  to be cast on any issue proposed to  be
considered  at the  meeting. The  time and  purpose or  purposes of  any special
meeting shall  be described  in the  notice required  by Section  1.04 of  these
Bylaws and only business within the purpose(s) described in such notice shall be
conducted at such meeting.

    1.03.   PLACE  OF MEETINGS;  POSTPONEMENTS AND  ADJOURNMENTS.   The Board of
Directors, the  Chairman  of the  Board,  the  President or  the  Secretary  may
designate  any place, either  within or without  the State of  Wisconsin, as the
place of meeting for  any annual meeting or  any special meeting, including  any
adjourned  meeting.  The Board  of  Directors, the  Chairman  of the  Board, the
President or the Secretary may postpone any previously scheduled annual  meeting
or  special meeting by giving public notice of the postponed meeting date at any
time prior to the scheduled meeting date.  If no designation is made, the  place
of  meeting shall be the principal office of the corporation. Any meeting may be
adjourned from  time  to time,  whether  or not  a  quorum is  present,  by  the
chairperson  of the meeting or by vote of a majority of the votes entitled to be
cast by the shares represented thereat.

    1.04.  NOTICES TO STOCKHOLDERS.

    (a)  REQUIRED NOTICE.  Notice may be communicated by mail, private  carrier,
or  any other means permissible under  Wisconsin law. Written notice stating the
scheduled place, day and hour of the meeting and, in case of a special  meeting,
the  purpose or purposes for which the  meeting is called, shall be communicated
or sent not less than ten (10) days,  unless a longer period is required by  the
Wisconsin  Business Corporation Law  or the Articles  of Incorporation, nor more
than ninety (90) days, unless a longer  period is permitted or a shorter  period
is  required by the Wisconsin  Business Corporation Law, before  the date of the
meeting, by or at the direction of  the Chairman of the Board, the President  or
the  Secretary, to each stockholder  of record entitled to  vote at such meeting
or, for  the fundamental  transactions described  in subsections  (b)(1) to  (4)
below,  for which the Wisconsin Business Corporation Law requires that notice be
given to stockholders not  entitled to vote, to  all stockholders of record.  At
least  twenty (20) days' notice shall be provided  if the purpose, or one of the
purposes, of the meeting is to consider  a plan of merger or share exchange  for
which  stockholder approval is required by law,  or the sale, lease, exchange or
other disposition of  all or  substantially all of  the corporation's  property,
with  or without good  will, otherwise than  in the usual  and regular course of
business. A stockholder  may waive  notice in  accordance with  Section 1.10  of
these Bylaws.

    (b)   FUNDAMENTAL TRANSACTIONS.  If a  purpose of any stockholder meeting is
to consider either: (1)  a proposed amendment to  the Articles of  Incorporation
(including  any restated articles); (2)  a plan of merger  or share exchange for
which stockholder approval is required by law; (3) the sale, lease, exchange  or
other  disposition of  all or substantially  all of  the corporation's property,
with or without good  will, otherwise than  in the usual  and regular course  of
business;  (4)  the dissolution  of the  corporation;  or (5)  the removal  of a
director, the notice must so state and in  cases (1), (2) and (3) above must  be
accompanied by, respectively, a copy or summary of the: (1) proposed articles of
amendment  or a copy of  the restated articles that  identifies any amendment or
other change; (2) proposed plan of

                                      I-4
<PAGE>
merger or share exchange; or (3) proposed transaction for disposition of all  or
substantially  all  of the  corporation's  property. If  the  proposed corporate
action creates dissenters' rights, the  notice must state that stockholders  and
beneficial stockholders are or may be entitled to assert dissenters' rights, and
must  be accompanied by  a copy of  Sections 180.1301 to  180.1331 (or successor
provisions) of the Wisconsin Business Corporation Law.

    1.05.   FIXING OF  RECORD DATE.   The  Board of  Directors, or  any  officer
authorized  by the Board of  Directors, may fix in advance  a date as the record
date for  one  or more  voting  groups  for any  determination  of  stockholders
entitled  to notice of a stockholders' meeting,  to demand a special meeting, to
vote, or to take  any other action, such  date in any case  to be not more  than
seventy  (70) days and, in case of  a meeting of stockholders, dividend or stock
split, not less than ten (10) days prior to the meeting or action requiring such
determination of  stockholders, and  may  fix the  record date  for  determining
stockholders entitled to a share dividend or distribution. If within thirty (30)
days  after the corporation receives  one or more written  demands for a special
stockholder  meeting  that  purport  to  satisfy  the  requirements  of  Section
180.0702(1)(b)  of  the Wisconsin  Business  Corporation Law  (or  any successor
provision) no record date has been fixed pursuant to the first sentence of  this
Section  1.05 for  the determination of  stockholders entitled to  demand such a
stockholder meeting, the  record date for  determining stockholders entitled  to
demand  such meeting  shall be  the date that  the first  stockholder signed the
demand. If no record date has been fixed pursuant to the first sentence of  this
Section  1.05 for the determination of stockholders entitled (A) to notice of or
to vote  at a  meeting of  stockholders prior  to the  time that  notice of  the
meeting  is mailed or otherwise delivered to  stockholders, or (B) to consent to
action without a meeting within thirty (30) days after the corporation  receives
the first written consent to stockholder action without a meeting, (a) the close
of  business on  the day  before the first  notice of  the meeting  is mailed or
otherwise delivered to stockholders or (b)  the date that the first  stockholder
signed  the  first  written consent  to  stockholder action  without  a meeting,
respectively,  shall  be  the  record   date  for  the  determination  of   such
stockholders.  When  a determination  of stockholders  entitled  to vote  at any
meeting of  stockholders  has  been  made as  provided  in  this  section,  such
determination shall be applied to any postponement or adjournment thereof unless
the  Board of Directors fixes a new record date and except as otherwise required
by law. A new record date must be set if a meeting is postponed or adjourned  to
a date more than 120 days after the date fixed for the original meeting.

    1.06.   QUORUM AND VOTING REQUIREMENTS.  Except as otherwise provided in the
Articles of  Incorporation  or in  the  Wisconsin Business  Corporation  Law,  a
majority  of the  votes entitled  to be  cast by  shares entitled  to vote  as a
separate voting group  on a  matter, represented in  person or  by proxy,  shall
constitute  a quorum of that voting group for action on that matter at a meeting
of stockholders. If a quorum exists, action on a matter, other than the election
of directors, by a voting group is approved if the votes cast within the  voting
group  favoring the action  exceed the votes  cast opposing the  action unless a
greater number  of  affirmative votes  is  required by  the  Wisconsin  Business
Corporation  Law, the Articles of Incorporation, or any other provision of these
Bylaws. If the Articles of  Incorporation or the Wisconsin Business  Corporation
Law  provide for voting by two (2) or more classes or voting groups on a matter,
action on that  matter is taken  only when voted  upon by each  of those  voting
groups counted separately.

    1.07.  CONDUCT OF MEETINGS.  The Chairman of the Board, or in his absence or
at  his  request,  the Vice  Chairman  of the  Board,  and in  his  absence, the
President, and  in the  President's  absence, a  Vice  President, and  in  their
absence, any person chosen by the stockholders present shall call the meeting of
the  stockholders to order and shall act  as chairperson of the meeting, and the
Secretary shall act as  secretary of all meetings  of the stockholders, but,  in
the  absence of the  Secretary, the chairperson  of the meeting  may appoint any
other person to act as secretary of the meeting.

    1.08.  PROXIES; BALLOTING  AND INSPECTORS OF ELECTION.   At all meetings  of
stockholders,  a stockholder  entitled to  vote may vote  in person  or by proxy
appointed in  writing  by the  stockholder  or by  his  or her  duly  authorized
attorney-in-fact.  Voting at  meetings of  stockholders need  not be  by written
ballot unless  so determined  by the  Board of  Directors, the  Chairman of  the
Board, the President or the

                                      I-5
<PAGE>
Secretary.  Voting at meetings of stockholders shall be conducted by one or more
inspectors of election appointed by the Board of Directors, the Chairman of  the
Board,  the President or the Secretary. However,  no director or person who is a
candidate for the office of director  shall be appointed as such inspector.  The
inspectors,  or  persons  representing  the inspector  if  the  inspector  is an
institution, before entering upon the discharge of their duties, shall take  and
subscribe  an oath faithfully to execute the duties of inspector at such meeting
with strict impartiality and according to the best of their ability.

    1.09.  STOCKHOLDER UNANIMOUS CONSENT WITHOUT A MEETING.  Any action required
by the Articles of Incorporation, Bylaws or any provision of law to be taken  at
a  meeting of  stockholders or  any other action  which may  be taken  at such a
meeting may be taken without a meeting  if consent in writing setting forth  the
action so taken shall be signed by all of the stockholders entitled to vote with
respect to the subject matter thereof and such consent shall have the same force
and effect as a unanimous vote.

    1.10.   STOCKHOLDER WAIVER  OF NOTICE.   A stockholder may  waive any notice
required  by  the   Wisconsin  Business   Corporation  Law,   the  Articles   of
Incorporation  or these Bylaws before  or after the date  and time stated in the
notice. The waiver shall be in writing and signed by the stockholder entitled to
the notice, shall contain the same information that would have been required  in
the notice under the Wisconsin Business Corporation Law except that the time and
place  of meeting need not be stated,  and shall be delivered to the corporation
for inclusion in the corporate records. A stockholder's attendance at a meeting,
in person or by proxy, waives objection to both of the following:

        (a) Lack  of notice  or  defective notice  of  the meeting,  unless  the
    stockholder at the beginning of the meeting or promptly upon arrival objects
    to holding the meeting or transacting business at the meeting.

        (b)  Consideration of  a particular  matter at  the meeting  that is not
    within the purpose described in  the meeting notice, unless the  stockholder
    objects to considering the matter when it is presented.

    1.11.   NOTICE OF STOCKHOLDER NOMINATION(S) AND/OR PROPOSAL(S).  Except with
respect to nomination(s) or proposal(s) adopted  or recommended by the Board  of
Directors  for inclusion  in the  corporation's proxy  statement for  its annual
meeting, a stockholder entitled to  vote at a meeting  may nominate a person  or
persons  for  election as  director(s) or  propose  action(s) to  be taken  at a
meeting  only  if  written  notice  of  any  stockholder  nomination(s)   and/or
proposal(s)  to be considered for a vote at an annual meeting of stockholders is
delivered personally or  mailed by  Certified Mail-Return  Receipt Requested  at
least  seventy (70)  days and not  more than  one hundred (100)  days before the
scheduled date  of such  meeting to  the  Secretary of  the corporation  at  the
principal  business  office  of  the corporation.  With  respect  to stockholder
nomination(s) for the election  of directors each such  notice shall set  forth:
(a)   the  name  and  address  of  the  stockholder  who  intends  to  make  the
nomination(s), of any beneficial owner of shares on whose behalf such nomination
is being made and of the person or persons to be nominated; (b) a representation
that the stockholder is a holder of record of stock of the corporation  entitled
to  vote at such meeting (including the number of shares the stockholder owns as
of the record date (or as of the most recent practicable date if no record  date
has  been set) and the length of time  the shares have been held) and intends to
appear in person or by  proxy at the meeting to  nominate the person or  persons
specified   in  the   notice;  (c)  a   description  of   all  arrangements  and
understandings between the stockholder or any beneficial holder on whose  behalf
it  holds such shares, and their respective affiliates, and each nominee and any
other person or persons  (naming such person or  persons) pursuant to which  the
nomination  or nominations  are to  be made by  the stockholder;  (d) such other
information regarding each nominee  proposed by such  stockholder as would  have
been  required to be included  in a proxy statement  filed pursuant to the proxy
rules of the Securities and Exchange  Commission (whether or not such rules  are
applicable) had each nominee been nominated, or intended to be nominated, by the
Board  of Directors; and (e) the consent of  each nominee to serve as a director
of the corporation if  so elected. With respect  to stockholder proposal(s)  for
action(s) to be

                                      I-6
<PAGE>
taken  at an annual meeting of stockholders, the notice shall clearly set forth:
(a) the name and address of the stockholder who intends to make the proposal(s);
(b) a representation that the stockholder is a holder of record of the stock  of
the  corporation entitled to vote at the meeting (including the number of shares
the stockholder owns as of the record date (or as of the most recent practicable
date if no record date has been set) and the length of time the shares have been
held) and  intends to  appear in  person or  by proxy  to make  the  proposal(s)
specified in the notice; (c) the proposal(s) and a brief supporting statement of
such  proposal(s); and (d)  such other information  regarding the proposal(s) as
would have been required to be included  in a proxy statement filed pursuant  to
the  proxy rules of the Securities and  Exchange Commission (whether or not such
rules are applicable).

    Except with respect to nomination(s)  or proposal(s) adopted or  recommended
by  the Board  of Directors for  inclusion in  the notice to  stockholders for a
special meeting of  stockholders, a stockholder  entitled to vote  at a  special
meeting  may nominate  a person  or persons  for election  as director(s) and/or
propose action(s)  to be  taken  at a  meeting only  if  written notice  of  any
stockholder  nomination(s) and/or proposal(s)  to be considered for  a vote at a
special meeting  is  delivered personally  or  mailed by  Certified  Mail-Return
Receipt  Requested to the Secretary of the corporation at the principal business
office of the corporation so that it is received in a reasonable period of  time
before  such special meeting and  only if such nomination  or proposal is within
the purposes described in the notice to stockholders of the special meeting. All
other notice requirements regarding stockholder nomination(s) and/or proposal(s)
applicable to annual meetings also apply to nomination(s) and/or proposal(s) for
special meetings.

    The chairperson of the meeting  may refuse to acknowledge the  nomination(s)
and/or  proposal(s) of  any person  made without  compliance with  the foregoing
procedures.  This  section  shall  not   affect  the  corporation's  rights   or
responsibilities with respect to its proxies or proxy statement for any meeting.

                                  ARTICLE II.
                               BOARD OF DIRECTORS

    2.01.   NUMBER.   The  number of directors  constituting the  whole Board of
Directors shall  be such  number as  shall be  fixed from  time to  time by  the
affirmative  vote of the  whole Board but in  no event shall  the number be less
than three. Until so fixed at a different number, the number shall be nine.* The
number of  directors at  any time  constituting  the whole  Board shall  not  be
reduced  so as  to shorten the  term of  any director then  in office. Directors
shall be stockholders of the corporation.

    The  directors  shall  hold  office   until  the  next  annual  meeting   of
stockholders  at which their  respective terms of office  shall expire and until
their respective successors are duly elected and qualified.

    2.02.  CLASSIFICATION.  The directors shall be divided into three classes as
nearly equal in number as  possible, the term of  one class expiring each  year.
Except for any director elected pursuant to Section 2.05 of these Bylaws and any
director  elected by the stockholders  to fill a vacancy  for the remainder of a
three year term, whose terms of office  may be less than three years,  directors
shall  be elected for three year terms. However, at any time when there shall be
a complete vacancy of the  Board, the directors of Class  I shall be elected  to
hold  office  until  the next  succeeding  annual meeting  of  stockholders; the
directors  of  Class  II   until  the  second   succeeding  annual  meeting   of
stockholders;  and the directors of Class  III until the third succeeding annual
meeting of  stockholders, and  in each  foregoing case,  until their  respective
successors  are duly elected and qualified.  If, at any meeting of stockholders,
directors of more than one class are to be elected, whether due to a vacancy  or
vacancies on the Board of Directors, or otherwise, each class of directors to be
elected at the meeting shall be nominated and voted for in a separate election.

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

*   Effective July 1, 1995, the Board of Directors fixed the number of directors
    at eight.

                                      I-7
<PAGE>
    2.03.   ELECTION AND TENURE.  Unless action is taken without a meeting under
these Bylaws, directors shall be elected by a plurality of the votes cast by the
shares entitled to vote  in the election  at a stockholders  meeting at which  a
quorum  is  present. Each  director  shall hold  office  until the  end  of such
director's term and until such director's  successor has been elected, or  until
such  director's prior death,  resignation or removal. A  director may resign at
any time by filing a written resignation with the Secretary of the corporation.

    2.04.  REMOVAL.  A director may  be removed from office only by  affirmative
vote  by a  majority if  for cause,  or at  least 80%  if without  cause, of the
aggregate number of votes  which the holders of  the then outstanding shares  of
Common  Stock and  Preferred Stock  are entitled to  cast, voting  together as a
class, in the election of directors.

    2.05.   VACANCIES.    Any  vacancy occurring  in  the  Board  of  Directors,
including  a vacancy created by  an increase in the  number of directors, may be
filled by the stockholders or the Board of Directors. If the directors remaining
in office constitute fewer than a quorum of the Board, the directors may fill  a
vacancy  by the  affirmative vote  of a majority  of all  directors remaining in
office. The director filling  the vacancy shall  serve for a  term equal to  the
remaining  term of the directors in the  class of directors in which the vacancy
occurred or in which the new director position was created.

    2.06.  REGULAR MEETINGS.  Regular meetings of the Board of Directors and any
committee thereof shall be held at such time and place, either within or without
the State of Wisconsin, as may from time  to time be fixed by the Board or  such
committee  without other notice  than the schedule prepared  by the Secretary or
the resolution or other action of  the Board or committee establishing the  time
and place of such regular meetings.

    2.07.   SPECIAL MEETINGS.  Special meetings of the Board of Directors may be
called by or at the request of the Board of Directors, the Executive  Committee,
the  Chairman of the Board, the President, any committee designated by the Board
with specific authority to do such or any two (2) directors. Special meetings of
any committee may be called by or at the request of the foregoing persons or the
chairman of the committee. The persons calling any special meeting of the  Board
of  Directors or committee may fix any place, either within or without the State
of Wisconsin, as the place for holding  any special meeting called by them,  and
if  no other place is fixed the place of meeting shall be the principal business
office of the corporation.

    2.08.  MEETINGS BY TELEPHONE OR OTHER COMMUNICATION TECHNOLOGY.  (a) Any  or
all  directors may participate in  a regular or special  meeting of the Board of
Directors or in a committee meeting by,  or conduct the meeting through the  use
of,  telephone or  any other  means of  communication by  which either:  (i) all
participating directors may simultaneously hear each other during the meeting or
(ii) all communication  during the  meeting is immediately  transmitted to  each
participating  director, and each participating  director is able to immediately
send messages to all other participating directors.

    (b) If a meeting will be conducted through the use of any means described in
paragraph (a), all participating directors shall  be informed that a meeting  is
taking   place  at  which  official  business  may  be  transacted.  A  director
participating in a meeting by any means described in paragraph (a) is deemed  to
be present in person at the meeting.

    2.09.  NOTICE OF MEETINGS.  Notice of each meeting of the Board of Directors
(unless otherwise provided in or pursuant to Section 2.06 of these Bylaws) shall
be  given by written notice delivered personally or mailed or given by telephone
or telegram to each director at his business address or at such other address as
such director shall have designated in writing filed with the Secretary, in each
case not less than 6 hours prior thereto. If mailed, such notice shall be deemed
to be delivered  when deposited  in the United  States mail  so addressed,  with
postage  thereon prepaid. If notice  be given by telegram,  such notice shall be
deemed to be delivered when the telegram is delivered to the telegraph  company;
if by telephone, at the time the call is completed. Whenever any notice whatever
is required to be given to any director of the corporation under the Articles of
Incorporation,  Bylaws or  any provision  of law,  a waiver  thereof in writing,
signed   at    any   time,    whether   before    or   after    the   time    of

                                      I-8
<PAGE>
meeting,  by the director entitled to such notice, shall be deemed equivalent to
the giving of  such notice.  The attendance  of a  director at  a meeting  shall
constitute a waiver of notice of such meeting, except where a director attends a
meeting  and  objects thereat  to the  transaction of  any business  because the
meeting is  not  lawfully  called  or  convened.  Neither  the  business  to  be
transacted  at, nor the purpose of, any  regular or special meeting of the Board
need be specified in the notice or waiver of notice of such meeting.

    2.10.   QUORUM.   Except as  otherwise provided  by the  Wisconsin  Business
Corporation  Law  or these  Bylaws, a  majority  of the  number of  directors as
provided in or pursuant to Section 2.01  shall constitute a quorum of the  Board
of  Directors, and a majority of the number of directors appointed to serve on a
committee shall constitute a quorum of the  committee. If at any meeting of  the
Board  of Directors or any  committee thereof there shall  be less than a quorum
present, a majority of the directors  present may adjourn the meeting from  time
to  time, without notice other than announcement  at the meeting, until a quorum
shall have been obtained, when any  business may be transacted which might  have
been transacted at the meeting as first convened had there been a quorum.

    2.11.    MANNER  OF ACTING.    The affirmative  vote  of a  majority  of the
directors present at a meeting at which a quorum is present shall be the act  of
the Board of Directors or any committee thereof unless the affirmative vote of a
greater  number is otherwise required by the Wisconsin Business Corporation Law,
the Articles of Incorporation, the Bylaws or any provision of law.

    2.12.  COMMITTEES.   The Board  of Directors, by  resolution adopted by  the
affirmative  vote of a majority of all  the directors then in office, may create
one or more committees, each committee to  consist of two (2) or more  directors
appointed  by the Board of Directors to serve as members of the committee, which
to the extent provided in the resolution as initially adopted, and as thereafter
supplemented or  amended by  further  resolution adopted  by  a like  vote,  may
exercise the authority of the Board of Directors. Notwithstanding the foregoing,
no  committee  may:  (a)  authorize distributions;  (b)  approve  or  propose to
stockholders action  that the  Wisconsin Business  Corporation Law  requires  be
approved by stockholders; (c) fill vacancies on the Board of Directors or any of
its  committees, except  that the Board  of Directors may  provide by resolution
that any vacancies on a committee shall  be filled by the affirmative vote of  a
majority  of  the  remaining  committee  members;  (d)  amend  the  Articles  of
Incorporation; (e) adopt, amend or repeal  Bylaws; (f) approve a plan of  merger
not  requiring stockholder approval;  (g) authorize or  approve reacquisition of
shares, except  according to  a formula  or method  prescribed by  the Board  of
Directors; or (h) authorize or approve the issuance or sale or contract for sale
of  shares, or  determine the designation  and relative  rights, preferences and
limitations of a class or series  of shares, except within limits prescribed  by
the Board of Directors.

    Unless  otherwise  provided  by  the  Board  of  Directors,  members  of any
committee shall serve at the  pleasure of the Board  of Directors. The Board  of
Directors  may elect one or more of its members as alternate members of any such
committee who may take the place of any absent member or members at any  meeting
of  such committee, upon request by the Chairman of the Board or upon request by
the chairperson of  such meeting. Each  such committee shall  fix its own  rules
(consistent  with  the  Wisconsin  Business  Corporation  Law,  the  Articles of
Incorporation and  these Bylaws)  governing the  conduct of  its activities  and
shall make such reports to the Board of Directors of its activities as the Board
of Directors may request. Unless otherwise provided by the Board of Directors in
creating  a committee,  a committee  may employ  counsel, accountants  and other
consultants to assist it in the exercise of authority.

    The provisions of  Section 2.09  shall also apply  to notice  and waiver  of
notice of meetings of any committee of the Board of Directors.

    2.13.   COMPENSATION.   The  Board of  Directors, by  affirmative vote  of a
majority of  the directors  then in  office, and  irrespective of  any  personal
interest of any of its members, may (a) establish reasonable compensation of all
directors  for services to the corporation  as directors, officers or otherwise,
and the  manner  and  time  and payment  thereof,  (b)  provide  for  reasonable
pensions,  disability  or death  benefits, and  other  benefits or  payments, to
directors, officers and employees and to

                                      I-9
<PAGE>
their estates,  families,  dependents  or  beneficiaries  on  account  of  prior
services  rendered by such directors, officers and employees to the corporation,
and (c)  provide  for  reimbursement  of reasonable  expenses  incurred  in  the
performance of directors' duties.

    2.14.  PRESUMPTION OF ASSENT.  A director who is present and is announced as
present  at a meeting of the Board of  Directors or a committee thereof at which
action on any corporate matter  is taken shall be  presumed to have assented  to
the action taken unless (a) the director objects at the beginning of the meeting
or  promptly  upon his  or her  arrival  to holding  the meeting  or transacting
business at the meeting,  or (b) the director's  dissent or abstention from  the
action  taken is  entered in  the minutes  of the  meeting, or  (c) the director
delivers his or  her written notice  of dissent or  abstention to the  presiding
officer  of the  meeting before  the adjournment  thereof or  to the corporation
immediately after the adjournment of the  meeting, or (d) the director  dissents
or  abstains from an action taken, minutes of the meeting are prepared that fail
to show the director's  dissent or abstention and  the director delivers to  the
corporation  a  written  notice of  that  failure promptly  after  receiving the
minutes. Such right  to dissent or  abstain shall  not apply to  a director  who
voted in favor of an action.

    2.15.  DIRECTOR UNANIMOUS CONSENT WITHOUT A MEETING.  Any action required or
permitted by the Articles of Incorporation, these Bylaws or any provision of law
to  be taken at a  Board of Directors meeting or  committee meeting may be taken
without a  meeting if  the  action is  taken  by all  members  of the  Board  or
committee.  The  action  shall be  evidenced  by  one or  more  written consents
describing the  action  taken, signed  by  each  director and  retained  by  the
corporation.  Action taken hereunder  is effective when  the last director signs
the consent, unless the consent specifies a different effective date. A  consent
signed  hereunder has the effect of a unanimous vote taken at a meeting at which
all directors or committee members were present, and may be described as such in
any document.

                                  ARTICLE III.
                                    OFFICERS

    3.01.  POSITIONS.  The officers of the corporation shall include a  Chairman
of  the Board,  a Vice Chairman  of the Board,  a President, the  number of Vice
Presidents provided for by the Board of Directors, a Treasurer, and a Secretary,
each of  whom  shall be  appointed  by the  Board  of Directors.  The  Board  of
Directors  shall also  designate a  Chief Executive  Officer, a  Chief Operating
Officer and  a  Chief  Financial  Officer. Such  other  officers  and  assistant
officers  as may be deemed necessary may be appointed by the Board of Directors.
Any two or more offices may be held by the same person.

    3.02.  RESIGNATION AND REMOVAL.   An officer shall  hold office until he  or
she  resigns, dies, is removed hereunder, or  a different person is appointed to
the office.  An officer  may resign  at any  time by  delivering an  appropriate
written  notice to the corporation. The resignation is effective when the notice
is delivered,  unless  the notice  specifies  a  later effective  date  and  the
corporation  accepts the later  effective date. Any officer  may be removed from
office by the affirmative vote of a majority of the whole Board of Directors  at
any time, with or without cause and notwithstanding the contract rights, if any,
of  the  person  removed. Except  as  provided  in the  preceding  sentence, the
resignation or  removal is  subject to  any remedies  provided by  any  contract
between   the  officer  and  the  corporation  or  otherwise  provided  by  law.
Appointment shall not of itself create contract rights.

    3.03.  VACANCIES.   A vacancy in any  office because of death,  resignation,
removal  or otherwise, shall be  filled by the Board  of Directors. The Board of
Directors may, from time to time, omit to elect one or more officers or may omit
to fill a  vacancy, and in  such case,  the designated duties  of such  officer,
unless  otherwise provided  in these  Bylaws, shall  be discharged  by the Chief
Executive Officer or such other officers as he or she may designate.

    3.04.  POWERS  AND DUTIES.   Subject  to such  limitations as  the Board  of
Directors may from time to time prescribe, the officers of the corporation shall
each  have  such powers  and  duties as  generally  pertain to  their respective
offices, as  well  as such  powers  and  duties as  from  time to  time  may  be

                                      I-10
<PAGE>
conferred  by  the  Chief  Executive  Officer or  the  Board  of  Directors. The
Treasurer and the  Assistant Treasurers  may be required  to give  bond for  the
faithful  discharge of their  duties, in such  sum and of  such character as the
Board of Directors may from time to time prescribe.

                                  ARTICLE IV.
                   CERTIFICATES FOR SHARES AND THEIR TRANSFER

    4.01.  STOCK CERTIFICATES  AND FACSIMILE SIGNATURES.   The certificates  for
shares  of  stock of  the  corporation shall  be  signed either  manually  or by
facsimile signature by  the Chief  Executive Officer,  the President  or a  Vice
President, and by the Secretary or an Assistant Secretary of the corporation, or
any other officer or officers that the Board of Directors designates, and may be
sealed with the seal of the corporation.

    The  certificates for  shares shall  be countersigned  and registered either
manually or by  facsimile signature  in such  manner, if  any, as  the Board  of
Directors  may from time to time prescribe. The transfer agent and the registrar
may, but  need  not be,  the  same  person or  agency.  In the  event  that  the
corporation  or its agent is  acting in the dual  capacity of transfer agent and
registrar, a single manual or facsimile signature may be used.

    In case any such person acting  as an officer, transfer agent or  registrar,
who  has  signed,  or  whose  facsimile  signature  has  been  placed  upon such
certificate, shall have ceased to be such officer, transfer agent or  registrar,
before  such certificate is issued,  it may be used  by the corporation with the
same effect as  if such person  had not  ceased to be  such at the  date of  its
issue.

    4.02.   TRANSFER OF STOCK.  The shares  of stock of the corporation shall be
transferable on the books of the corporation upon request by the holders thereof
or by duly authorized attorney, upon surrender and cancellation of  certificates
for  a like number  of shares of the  same class and series  of stock, with duly
executed assignment and power of transfer endorsed thereon or attached  thereto,
and  with such proof of the authenticity  of the signature as the corporation or
its agents may reasonably require.

    Prior to due  presentment of a  certificate for shares  for registration  of
transfer  the corporation may treat  the registered owner of  such shares as the
person exclusively entitled to vote,  to receive notifications and otherwise  to
have and exercise all the rights and powers of an owner. Where a certificate for
shares  is presented to the corporation with a request to register for transfer,
the corporation shall not be liable to  the owner or any other person  suffering
loss  as a result of such registration of  transfer if (a) there were on or with
the certificate the necessary endorsements, and (b) the corporation had no  duty
to  inquire into adverse claims or has discharged any such duty. The corporation
may  require  reasonable  assurance  that  said  endorsements  are  genuine  and
effective  and in compliance with such other regulations as may be prescribed by
or under the authority of the Board of Directors.

    4.03.  LOST, DESTROYED OR STOLEN CERTIFICATES.  Where the owner claims  that
his  certificate for shares has been lost,  destroyed or wrongfully taken, a new
certificate shall be issued in place thereof if the owner (a) so requests before
the corporation has notice that  such shares have been  acquired by a bona  fide
purchaser,  (b) files with  the corporation a sufficient  indemnity bond and (c)
satisfies such other reasonable  requirements as may be  prescribed by or  under
the authority of the Board of Directors.

    4.04.   SHARES WITHOUT  CERTIFICATES.  The Board  of Directors may authorize
the issuance of any shares of any of its classes or series without certificates.
The authorization does  not affect  shares already  represented by  certificates
until  the certificates are surrendered to  the corporation. Within a reasonable
time after  the  issuance  or  transfer  of  shares  without  certificates,  the
corporation shall send the stockholder a written statement that includes (1) all
of  the  information  required  on  share  certificates  and  (2)  any  transfer
restrictions applicable to the shares.

                                   ARTICLE V.
                                INDEMNIFICATION

    5.01.  MANDATORY INDEMNIFICATION.   The corporation  shall indemnify to  the
fullest  extent permitted by law any person who  is or was a party or threatened
to be made  a party  to any legal  proceeding by  reason of the  fact that  such
person  is or was a director or officer of the corporation, or is or was serving
at the  request  of  the  corporation  as  a  director  or  officer  of  another
enterprise,  against expenses  (including attorney  fees), judgments,  fines and
amounts paid in  settlement actually and  reasonably incurred by  the person  in
connection with such legal proceeding.

    5.02.   CERTAIN  DEFINITIONS.   As used in  this Article  V, (a) "indemnify"
includes the advancement  of expenses upon  receipt of an  undertaking to  repay
upon  specified  conditions, (b)  "fullest extent  permitted  by law"  means the
fullest extent to which  indemnity may lawfully be  provided by, pursuant to  or
consistently with, the provisions of subsections (1) and (2) of Section 180.05**
of the Wisconsin Statutes (or any successor provision), a bylaw under subsection
(6)  of that Section** (or any successor provision) or any other applicable law,
whether statutory  or  otherwise,  (c) "person"  includes  the  person's  heirs,
executors  and  administrators,  (d) "legal  proceeding"  means  any threatened,
pending or completed action, suit or proceeding,  whether or not by or in  right

partnership, joint venture,  trust, dividend reinvestment  plan, stock  purchase
plan,  employee benefit  plan or  other plan  or entity,  (f) "expenses" include
expenses in the  enforcement of  rights under this  Bylaw and  any excise  taxes
assessed  with respect to an employee benefit plan  and (g) in respect of any of
such plans, (i)  "serving at the  request of  the corporation as  a director  or
officer" includes serving at the request of the corporation in any capacity that
involves  services or  duties with  respect to the  plan or  its participants or
beneficiaries and (ii) action reasonably believed to be in the interest of  such
participants  or beneficiaries shall be deemed  reasonably believed to be in, or
not opposed to, the best interests of the corporation.

    5.03.  LEGAL ENFORCEABILITY.  The rights provided to any person by the terms
of this Article V shall be  legally enforceable against the corporation by  such
person, who shall be presumed to have relied on the provisions of this Article V
in  undertaking or continuing any of the positions with the corporation or other
enterprise referred to in Section 5.01.

    5.04.   LIMITATION  ON MODIFICATION  OR  TERMINATION.   No  modification  or
termination  of this Article V  shall be effected which  would impair any rights
hereunder arising at any time out of events occurring prior to such modification
or termination.

    5.05.  NON-EXCLUSIVE BYLAW.  This Article V is not intended be to  exclusive
and  accordingly shall not  be construed as  impairing in any  way the power and
authority of the corporation, to  the extent legally permissible without  regard
to  this Article V, in its discretion to  indemnify or agree to indemnify, or to
purchase insurance indemnifying, any employee, agent or other person.

                                  ARTICLE VI.
                        OTHER INDEMNIFICATION PROVISIONS

    6.01.   INDEMNIFICATION FOR  SUCCESSFUL DEFENSE.   Within  twenty (20)  days
after  receipt of  a written request  pursuant to Section  6.03, the corporation
shall indemnify  a  director or  officer,  to the  extent  he or  she  has  been
successful  on the merits or  otherwise in the defense  of a proceeding, for all
reasonable expenses incurred in the proceeding if the director or officer was  a
party because he or she is a director or officer of the corporation.

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

**  The currently applicable statutory provisions are Sections 180.0850 to
    180.0859 of the Wisconsin Business Corporation Law.

<PAGE>
    6.02.  OTHER INDEMNIFICATION.  (a) In cases not included under Section 6.01,
the  corporation shall indemnify  a director or  officer against all liabilities
and expenses incurred by the  director or officer in  a proceeding to which  the
director  or officer was a party  because he or she is  a director or officer of
the corporation, unless liability was  incurred because the director or  officer
breached  or failed to perform a duty he  or she owes to the corporation and the
breach or failure to perform constitutes any of the following:

        (1) A  willful  failure to  deal  fairly  with the  corporation  or  its
    stockholders  in connection with  a matter in which  the director or officer
    has a material conflict of interest.

        (2) A violation  of criminal  law, unless  the director  or officer  had
    reasonable  cause  to believe  that  his or  her  conduct was  lawful  or no
    reasonable cause to believe that his or her conduct was unlawful.

        (3) A transaction from which the director or officer derived an improper
    personal profit.

        (4) Willful misconduct.

    (b) Determination of whether indemnification is required under this  Section
or Article V shall be made pursuant to Section 6.05.

    (c)  The  termination  of a  proceeding  by judgment,  order,  settlement or
conviction, or upon a  plea of no  contest or an equivalent  plea, does not,  by
itself,  create a presumption that indemnification of the director or officer is
not required under this Section.

    6.03.  WRITTEN  REQUEST.  A  director or officer  who seeks  indemnification
under  Article V or  Sections 6.01 or 6.02  shall make a  written request to the
corporation.

    6.04.  NONDUPLICATION.   The corporation shall not  indemnify a director  or
officer  under Sections 6.01 or  6.02 if the director  or officer has previously
received indemnification or allowance of expenses from any person, including the
corporation, in connection with  the same proceeding.  However, the director  or
officer has no duty to look to any other person for indemnification.

    6.05.   DETERMINATION  OF RIGHT  TO INDEMNIFICATION.   (a)  Unless otherwise
provided by the Articles  of Incorporation or by  written agreement between  the
director  or  officer  and  the corporation,  the  director  or  officer seeking
indemnification under  Article  V  or  Section 6.02  shall  select  one  of  the
following means for determining his or her right to indemnification:

        (1)  By a majority vote of a quorum of the Board of Directors consisting
    of directors not at the time parties to the same or related proceedings.  If
    a  quorum of disinterested directors cannot be obtained, by majority vote of
    a committee duly appointed by the  Board of Directors and consisting  solely
    of  two (2) or more directors who are not at the time parties to the same or
    related proceedings.  Directors  who are  parties  to the  same  or  related
    proceedings may participate in the designation of members of the committee.

        (2)  By independent legal counsel  selected by a quorum  of the Board of
    Directors or  its committee  in the  manner prescribed  in sub.  (1) or,  if
    unable  to obtain such a quorum or committee, by a majority vote of the full
    Board of  Directors, including  directors who  are parties  to the  same  or
    related proceedings.

        (3)  By a  panel of three  (3) arbitrators consisting  of one arbitrator
    selected by those directors  entitled under sub.  (2) to select  independent
    legal  counsel, one arbitrator  selected by the  director or officer seeking
    indemnification and  one  arbitrator selected  by  the two  (2)  arbitrators
    previously selected.

        (4)  By  an  affirmative vote  of  shares  represented at  a  meeting of
    stockholders at which a quorum of the voting group entitled to vote  thereon
    is  present. Shares owned by, or voted under the control of, persons who are
    at the  time  parties  to  the  same  or  related  proceedings,  whether  as
    plaintiffs  or defendants  or in  any other  capacity, may  not be  voted in
    making the determination.

                                      I-13
<PAGE>
        (5) By a court under Section 6.08.

        (6) By  any  other  method  provided for  in  any  additional  right  to
    indemnification.

    (b)  In  any  determination  under  (a),  the  burden  of  proof  is  on the
corporation to prove by clear and convincing evidence that indemnification under
Article V or Section 6.02 should not be allowed.

    (c) A written determination as to a director's or officer's  indemnification
under  Article V or Section 6.02 shall  be submitted to both the corporation and
the director or officer within 60 days of the selection made under (a).

    (d) If it is determined that indemnification is required under Article V  or
Section  6.02,  the  corporation  shall pay  all  liabilities  and  expenses not
prohibited by Section  6.04 within ten  (10) days after  receipt of the  written
determination under (c). The corporation shall also pay all expenses incurred by
the director or officer in the determination process under (a).

    6.06.  ADVANCE OF EXPENSES.  Within ten (10) days after receipt of a written
request by a director or officer who is a party to a proceeding, the corporation
shall  pay  or reimburse  his  or her  reasonable  expenses as  incurred  if the
director or officer provides the corporation with all of the following:

        (1) A written affirmation of his or her good faith belief that he or she
    has not breached or failed to perform his or her duties to the corporation.

        (2) A written undertaking, executed personally or on his or her  behalf,
    to  repay the allowance to the extent that it is ultimately determined under
    Section 6.05 that  indemnification under Article  V or Section  6.02 is  not
    required  and that indemnification  is not ordered by  a court under Section
    6.08(b)(2). The  undertaking under  this subsection  shall be  an  unlimited
    general  obligation of the  director or officer and  may be accepted without
    reference to his or her ability to repay the allowance. The undertaking  may
    be secured or unsecured.

    6.07.   LIMITATIONS ON INDEMNIFICATION.   (a) Regardless of the existence or
rights under these  Bylaws and  additional rights to  indemnification under  any
agreement  with the corporation, the corporation  shall not indemnify a director
or officer, or permit a director or officer to retain any allowance of expenses,
unless it is determined by or on behalf of the corporation that the director  or
officer  did  not breach  or  fail to  perform  a duty  he  or she  owes  to the
corporation which constitutes conduct under Section 6.02(a)(1), (2), (3) or (4).
A director or  officer who is  a party to  the same or  related proceedings  for
which  indemnification or an allowance of expenses is sought may not participate
in a determination under this subsection.

    (b) Sections 6.01 to 6.12  do not affect the  corporation's power to pay  or
reimburse  expenses incurred by  a director or  officer in any  of the following
circumstances.

        (1) As a witness in a proceeding to which he or she is not a party.

        (2) As a plaintiff or petitioner in a proceeding because he or she is or
    was an employee, agent, director or officer of the corporation.

    6.08.  COURT-ORDERED INDEMNIFICATION.   (a) Except as provided otherwise  by
written  agreement  between  the  director or  officer  and  the  corporation, a
director or officer who is a party to a proceeding may apply for indemnification
to the  court  conducting  the  proceeding or  to  another  court  of  competent
jurisdiction.  Application shall  be made  for an  initial determination  by the
court under  Section  6.05(a)(5)  or for  review  by  the court  of  an  adverse
determination  under Section 6.05(a) (1), (2), (3), (4) or (6). After receipt of
an application, the court shall give any notice it considers necessary.

    (b) The  court shall  order  indemnification if  it  determines any  of  the
following:

        (1)  That the director  or officer is  entitled to indemnification under
    Article V or Sections 6.01 or 6.02.

                                      I-14
<PAGE>
        (2) That the director  or officer is fairly  and reasonably entitled  to
    indemnification  in view  of all  the relevant  circumstances, regardless of
    whether indemnification is required under Article V or Section 6.02.

    (c) If  the court  determines under  (b)  that the  director or  officer  is
entitled  to  indemnification,  the  corporation  shall  pay  the  director's or
officer's expenses incurred to obtain the court-ordered indemnification.

    6.09.    INDEMNIFICATION  AND  ALLOWANCE   OF  EXPENSES  OF  EMPLOYEES   AND
AGENTS.   The corporation shall indemnify an  employee of the corporation who is
not a director or officer of the corporation,  to the extent that he or she  has
been  successful on the merits or otherwise  in defense of a proceeding, for all
reasonable expenses  incurred in  the proceeding  if the  employee was  a  party
because  he  or  she  was  an employee  of  the  corporation.  In  addition, the
corporation may indemnify and allow reasonable expenses of an employee or  agent
who  is not a director  or officer of the corporation  to the extent provided by
the Articles of Incorporation or these Bylaws, by general or specific action  of
the Board of Directors or by contract.

    6.10.   INSURANCE.   The corporation may purchase  and maintain insurance on
behalf of an individual who  is an employee, agent,  director or officer of  the
corporation  against liability asserted against or incurred by the individual in
his or her capacity  as an employee, agent,  director or officer, regardless  of
whether the corporation is required or authorized to indemnify or allow expenses
to  the individual against the same liability  under Article V or Sections 6.01,
6.02, 6.06, 6.07 and 6.09.

    6.11.  SECURITIES  LAW CLAIMS.   (a) Pursuant  to the public  policy of  the
State  of Wisconsin, the corporation shall provide indemnification and allowance
of expenses  and may  insure for  any liability  incurred in  connection with  a
proceeding  involving securities  regulation described  under (b)  to the extent
required or permitted under Article V or Sections 6.01 to 6.10.

    (b) Article V and Sections 6.01 to  6.10 apply, to the extent applicable  to
any  other proceeding, to  any proceeding involving a  federal or state statute,
rule or  regulation  regulating  the  offer, sale  or  purchase  of  securities,
securities brokers or dealers, or investment companies or investment advisers.

    6.12.   LIBERAL CONSTRUCTION.   In order  for the corporation  to obtain and
retain qualified  directors, officers  and employees,  the foregoing  provisions
shall  be liberally administered  in order to  afford maximum indemnification of
directors, officers and, where Section 6.09 of these Bylaws applies,  employees.
The  indemnification above provided for shall be granted in all applicable cases
unless to do so  would clearly contravene law,  controlling precedent or  public
policy.

                                  ARTICLE VII.
                     CONTRACTS, CHECKS, NOTES, BONDS, ETC.

    7.01.   CONTRACTS.   The  Board of  Directors may  authorize any  officer or
officers, agent or agents, to enter into any contract or execute or deliver  any
document  or instrument, whether of conveyance or  otherwise, in the name of and
on behalf of the corporation, and such authorization may be general or  confined
to specific instances.

    7.02.  CHECKS, DRAFTS, ETC.  All checks and drafts on the corporation's bank
accounts  and all bills  of exchange and promissory  notes, and all acceptances,
obligations and other instruments for the payment of money, shall be signed  or,
in  the case of wire transfers, shall be authorized by such officer or officers,
employee or employees or agent or  agents as shall be thereunto authorized  from
time  to  time by  the Board  of Directors;  provided that  checks drawn  on the
corporation's bank accounts may bear the facsimile signature of such officer  or
officers,  employee or employees, or  agent or agents as  the Board of Directors
shall authorize;  and provided  further that  in  the case  of notes,  bonds  or
debentures issued under a trust instrument of the corporation and required to be
signed  by two officers of the corporation,  the signatures of either or both of
such officers may be in facsimile if specifically authorized and directed by the
Board of Directors  of the corporation  and if such  notes, bonds or  debentures

                                      I-15
<PAGE>
are  required to be authenticated by a corporate trustee which is a party to the
trust instrument. In  case any such  officer who has  signed or whose  facsimile
signature  has been  placed upon  such instrument shall  have ceased  to be such
officer before such instrument  is issued, it may  be issued by the  corporation
with the same effect as if such officer had not ceased to be such at the date of
its issue.

                                 ARTICLE VIII.
                                  FISCAL YEAR

                               EFFECT OF HEADINGS

    The  descriptive headings and  references to Articles  and Sections in these
Bylaws were formulated, used and inserted herein for convenience only and  shall
not  be deemed to  affect the meaning  or construction of  any of the provisions
hereof.

                                  ARTICLE XI.
                                   AMENDMENTS

    11.01.  BY STOCKHOLDERS.   These Bylaws may be  amended or repealed and  new
Bylaws  may be adopted by the stockholders  by the vote provided in Section 1.06
of these Bylaws  except as  specifically provided below  or in  the Articles  of
Incorporation.  If authorized by the Articles of Incorporation, the stockholders
may adopt or amend a Bylaw that fixes a greater or lower quorum requirement or a
greater voting requirement  for stockholders  or voting  groups of  stockholders
than  otherwise  is  provided in  the  Wisconsin Business  Corporation  Law. The
adoption or amendment  of a Bylaw  that adds,  changes or deletes  a greater  or
lower  quorum requirement or a greater  voting requirement for stockholders must
meet the same  quorum requirement and  be adopted  by the same  vote and  voting
groups  required to take action under the  quorum and voting requirement then in
effect.

    11.02.  BY DIRECTORS.  Except as the Articles of Incorporation may otherwise
provide, these Bylaws  may also be  amended or  repealed and new  Bylaws may  be
adopted  by the  Board of Directors  by the  vote provided in  Sections 2.10 and
2.11, but (a) no Bylaw adopted by the stockholders shall be amended, repealed or
readopted by the Board of  Directors if such Bylaw provides  that it may not  be
amended, repealed or readopted by the Board of Directors and (b) a Bylaw adopted
or  amended by the stockholders that fixes a greater or lower quorum requirement
or a greater  voting requirement for  the Board of  Directors than otherwise  is
provided  in  the  Wisconsin Business  Corporation  Law  may not  be  amended or
repealed by the Board of Directors  unless the Bylaw expressly provides that  it
may be amended or repealed by a specified vote of the Board of Directors. Action
by  the Board of Directors to adopt or  amend a Bylaw that changes the quorum or
voting requirement  for  the  Board  of Directors  must  meet  the  same  quorum
requirement  and be adopted by  the same vote required  to take action under the
quorum and  voting  requirement  then  in  effect,  unless  a  different  voting
requirement  is specified  as provided by  the preceding sentence.  A Bylaw that
fixes a greater or lower quorum requirement or a greater voting requirement  for
stockholders  or voting groups of stockholders than otherwise is provided in the
Wisconsin Business Corporation Law  may not be adopted,  amended or repealed  by
the Board of Directors.

    11.03.    IMPLIED  AMENDMENTS.    Any  action  taken  or  authorized  by the
stockholders or by the Board of Directors, which would be inconsistent with  the
Bylaws  then  in effect  but is  taken or  authorized  by a  vote that  would be
sufficient to amend the Bylaws so that the Bylaws would be consistent with  such
action, shall be given the same effect as though the Bylaws had been temporarily
amended  or suspended  so far, but  only so far,  as is necessary  to permit the
specific action so taken or authorized.

    11.04.  VOTE REQUIRED FOR  CERTAIN AMENDMENTS.  Notwithstanding anything  in
these  Bylaws to  the contrary, the  provisions of Section  1.09, Sections 2.01,
2.02, 2.04, and 2.09, Article V and  this Section 11.04***, may be amended  only
by  the affirmative vote of at least 80%  of the aggregate number of votes which
the holders of the then outstanding shares of Common Stock and Preferred  Stock,
voting together as a class, are entitled to cast in an election of directors.

    1.  BOARD OF DIRECTORS.  The management of this Corporation shall be  vested
in  a Board of Directors composed  of not less than three  (3) and not more than
seventeen (17)  members,  who  shall  be elected  by  the  stockholders  of  the
Corporation  in the manner  provided by the  Bylaws, which may  provide that the
directors shall  be  divided  into  three classes  as  contemplated  in  Section
180.0806  of the Wisconsin Statutes or any  successor provision. It shall not be
necessary that  directors be  stockholders  in the  Corporation. The  number  of
directors shall be fixed from time to time by the Bylaws, and such number may be
increased or decreased within the above limits in such manner as may be provided
by  the Bylaws. Vacancies  in the Board caused  by an increase  in the number of
directors or by  death, resignation,  disqualification, or other  cause, may  be
filled by the remaining directors or by the stockholders at an annual or special
meeting, as may be provided by the Bylaws.

                                   ARTICLE V
                          DESCRIPTION OF CAPITAL STOCK

    The  total authorized number of shares that may be issued by the Corporation
and that the Corporation  will henceforth be authorized  to have is one  hundred
sixty-seven  million (167,000,000)  of the par  value per  share hereinafter set
forth.

                                      J-1
<PAGE>
    A description of  the classes of  shares and  a statement of  the number  of
shares  in each  class and  the relative  rights, voting  power, and preferences
granted to  and  restrictions imposed  upon  the shares  of  each class  are  as
follows:

    1.   AUTHORIZED NUMBER AND CLASSES OF  SHARES.  Such shares shall be divided
into two  classes to  be designated,  respectively, Preferred  Stock and  Common
Stock. The total authorized number of shares of Preferred Stock is seven million
(7,000,000)  having a par value of one hundred dollars ($100) per share, and the
total authorized number of shares of  Common Stock is one hundred sixty  million
(160,000,000)  having a  par value  of two dollars  and fifty  cents ($2.50) per
share.

    2.  ISSUANCE  AND TERMS  OF PREFERRED  STOCK.   The Preferred  Stock may  be
issued  in series, each of which  series shall have such distinctive designation
as may be fixed by the Board of Directors prior to the issuance or allotment  of
any  share of  such series,  provided that such  designation shall  in each case
include  the  words  "Preferred  Stock".  The  Board  of  Directors  is   hereby
authorized,  within  the  limitations and  restrictions  hereinafter  stated and
within the limits of the WBCL, to fix from time to time, in respect of shares of
Preferred Stock at the time unallotted, the dividend rates and times of payment,
the redemption  price, and  liquidation  price or  preference  as to  assets  in
voluntary liquidation of the shares of any series of Preferred Stock (except the
series  designated  "Cumulative Preferred  Stock, $3.60  Series," in  respect of
which such  provisions are  hereinafter  set forth)  and  the number  of  shares
constituting any series of Preferred Stock.

    3.  PREFERENCES OF PREFERRED STOCK.

    a.   DIVIDENDS.  The  holders of shares of  Preferred Stock, irrespective of
the series thereof,  shall be entitled  to receive in  preference to the  Common
Stock, when and as declared by the Board of Directors of the Corporation, out of
its  net earnings or  surplus, cumulative dividends  at such rate  as shall have
been fixed for the series of which such shares are a part, and no more,  payable
to  shareholders of record on such dates  and for such dividend periods as shall
be fixed by the Board of Directors of the Corporation. So long as dividends  are
in  default in whole  or in part  on a series  of Preferred Stock  for any prior
dividend period  for  such series  of  Preferred  Stock, any  dividends  on  the
Preferred Stock shall be divided among the outstanding series of Preferred Stock
for  which dividends  are accumulated and  unpaid for any  prior dividend period
applicable thereto in  proportion to the  aggregate amounts that  then would  be
distributable  to the  holders of  Preferred Stock  of each  such series  if all
dividends  accumulated  thereon  and  unpaid  for  all  prior  dividend  periods
applicable  thereto were paid  and declared thereon. Dividends  on each share of
Preferred Stock shall begin to  accrue on the first  day of the dividend  period
during  which the original  issue of a  certificate for such  share shall occur;
provided, however, that, in the case of any series of Preferred Stock issued  in
exchange  for a series of preferred stock, par value $2.50 per share of Northern
States Power Company, a  Minnesota corporation, which was  created after May  6,
1970,  the Board of Directors,  in its discretion, may  fix the date of original
issue of  the shares  of such  series as  the date  from which  dividends  shall
accrue.

    b.  LIQUIDATION AND DISSOLUTION.  In the event of any distribution of assets
of the Corporation other than by dividends from net earnings or surplus, whether
upon  voluntary liquidation  or dissolution  or upon  involuntary liquidation or
dissolution of the  Corporation, the holders  of the shares  of Preferred  Stock
shall  be entitled, in  preference to the  Common Stock, to  one hundred dollars
($100) per share in  the case of involuntary  liquidation or dissolution and  to
such amount per share in the case of voluntary liquidation or dissolution (which
may differ from that payable in involuntary liquidation or dissolution) as shall
have  been fixed by the Board of Directors for the shares of the series of which
they are a part, plus in each case an amount equal to all dividends  accumulated
and unpaid thereon, and no more. The consolidation or merger of this Corporation
with  or into any  other corporation or  corporations shall not  be deemed to be
distribution of assets or liquidation  or dissolution of the Corporation  within
the meaning of any provisions hereof.

    If  upon  any such  distribution  of assets  of  the Corporation  the assets
distributable among the holders  of the Preferred Stock  of all series shall  be
insufficient  to pay in full the amounts to which the holders of Preferred Stock
of  all  series  are  entitled  under  the  foregoing  provisions,  the   amount

                                      J-2
<PAGE>
distributable  to the  holders of  all shares of  Preferred Stock  of all series
shall be apportioned among  them ratably in proportion  to the amounts to  which
they are, respectively, entitled in accordance with such foregoing provisions.

    c.   DIVIDEND ARREARAGES.  Dividends may  be paid upon the Common Stock only
when dividends have been paid, or declared and set apart for payment in full, on
the Preferred Stock of all series from the date on which dividends thereon began
to accrue to  the beginning of  the current dividend  periods, but whenever  all
such  dividends have been paid, or declared  and funds set apart for the payment
thereof in full, upon the Preferred Stock of all series then dividends upon  the
Common Stock may be declared, payable then or thereafter out of any net earnings
or  surplus then remaining. The holders of Preferred Stock shall not be entitled
to receive any amounts  upon any distribution of  the assets of the  Corporation
other  than by dividends from net earnings or surplus in excess of the amount to
which  they  are,  respectively,  entitled  in  accordance  with  the  foregoing
provisions  hereof, but after the payment of such amounts in accordance with the
provisions hereinabove set forth,  the holders of Common  Stock, subject to  the
rights  of  holders of  stock  of any  other  class hereafter  authorized, shall
receive all further amounts in distribution of such assets of the Corporation.

    4.  REDEMPTION OF PREFERRED STOCK.   The Corporation, at its option, may  at
any  time and from  time to time redeem  the whole or any  part of the Preferred
Stock of any series or all series, upon at least thirty days' previous notice by
mail or publication given to the holders of record of the shares to be  redeemed
or  upon such other period and form of notice  as shall be fixed by the Board of
Directors in the resolution establishing such  series, by paying for each  share
to  be redeemed  the redemption  price which  shall have  been fixed,  as herein
provided, for the shares of the series of  which it is a part plus in each  case
an  amount equal to the dividends upon such shares so to be redeemed at the rate
or rates fixed  with respect  to such  shares from the  date or  dates on  which
dividends  on such shares began  to accrue to the  date fixed for the redemption
thereof less the amount of dividends  theretofore paid thereon, such payment  to
be  made only on presentation and  surrender for cancellation of the certificate
or certificates  representing  the share  or  shares so  called  for  redemption
properly  endorsed or assigned by the owner  of record thereof. If less than all
the outstanding shares of the Preferred Stock are to be redeemed, the shares  to
be  redeemed shall be determined  by the Board of  Directors of the Corporation,
either by lot, or by redemption pro rata, as the Board of Directors see fit.  If
the  notice  of redemption  hereinabove provided  for shall  have been  given as
hereinabove provided and if on or  before the redemption date specified in  such
notice  funds necessary for the redemption of the share or shares to be redeemed
shall have been set apart, as a trust fund, so as to be available therefor, then
notwithstanding that any certificate for the shares of Preferred Stock so to  be
redeemed   shall  not  have  been   surrendered  for  cancellation,  the  shares
represented thereby from and after the date of redemption so specified shall  no
longer  be deemed outstanding  and the right to  receive dividends thereon shall
cease to accrue and all  rights of the holders of  the shares to be redeemed  as
shareholders  of the  Corporation, except  the right  to receive  the redemption
price without interest upon  endorsement and surrender  of the certificates  for
said shares so redeemed, shall cease and terminate.

    5.  VOTING RIGHTS.

    a.    NUMBER OF  VOTES.   The  holders of  the  Preferred Stock  (other than
Preferred Stock  of the  series designated  "Cumulative Preferred  Stock,  $3.60
Series")  shall be entitled to one vote for each share thereof held by them, the
holders of  Preferred  Stock  heretofore  or  hereafter  issued  of  the  series
designated "Cumulative Preferred Stock, $3.60 Series" shall be entitled to three
votes  for each share thereof held by them,  and the holders of the Common Stock
shall be entitled to  one vote for  each share thereof  held by them;  provided,
however, that:

        (i)  If and when dividends payable on  the Preferred Stock of any series
    at the time outstanding are in default in an amount equivalent to the amount
    payable thereon during  the immediately preceding  twelve month period,  and
    until  such default  shall have been  remedied as  hereinafter provided, the
    preferred shareholders,  voting as  a class  and without  regard to  series,
    shall  be entitled  to elect the  smallest number of  directors necessary to
    constitute a majority of the full

                                      J-3
<PAGE>
    Board of  Directors, and  the common  shareholders, voting  separately as  a
    class,   shall  be  entitled  to  elect   the  remaining  directors  of  the
    Corporation. Upon accrual of  such special right of  the Preferred Stock,  a
    meeting  of the  preferred and the  common shareholders for  the election of
    directors shall be held upon notice promptly given as provided in the Bylaws
    for a special meeting by the President or the Secretary of the  Corporation.
    If  within  fifteen days  after the  accrual  of such  special right  of the
    Preferred Stock the  President and  the Secretary of  the Corporation  shall
    fail  to call such meeting, then such  meeting shall be held upon notice, as
    provided in the Bylaws for  a special meeting, given  by the holders of  not
    less  than  1,000  shares  of  the Preferred  Stock  after  filing  with the
    Corporation of notice of their  intention to do so.  The terms of office  of
    all  persons  who may  be directors  of  the Corporation  at the  time shall
    terminate upon the election of a majority  of the Board of Directors by  the
    preferred  shareholders, whether or not the common shareholders shall at the
    time of  such  termination  have  elected the  remaining  directors  of  the
    Corporation;  thereafter during the continuance of such special right of the
    Preferred Stock to elect a majority  of the Board of Directors, the  holders
    of  such stock, voting as a class, shall  be entitled to elect a majority of
    the Board  of  Directors  and  the  holders  of  the  Common  Stock,  voting
    separately as a class, shall be entitled to elect the remaining directors of
    the  corporation;  and all  directors so  elected,  whether at  such special
    meeting or any adjournment thereof, or at any subsequent annual meeting  for
    the  election  of directors,  held during  the  continuance of  such special
    right, shall hold office until the next succeeding annual election and until
    their respective successors, elected  by the preferred shareholders,  voting
    as  a class, and the common shareholders, voting as a class, are elected and
    qualified, unless  their  terms of  office  shall be  sooner  terminated  as
    hereinafter  provided. However, if and when all dividends then in default on
    the Preferred Stock shall  thereafter be paid (and  such dividends shall  be
    declared  and paid out  of any funds  legally available therefor  as soon as
    reasonably practicable), the Preferred Stock shall thereupon be divested  of
    such  special right herein provided for to  elect a majority of the Board of
    Directors, but subject always to the same provisions for the vesting of such
    special right in such  stock in the  case of any  similar future default  or
    defaults,  and  the  election  of  directors  by  the  preferred  and common
    shareholders, voting without regard to class,  shall take place at the  next
    succeeding  annual  meeting  for  the  election  of  directors,  or  at  any
    adjournment thereof. The terms of office of all persons who may be directors
    of the Corporation at the time  of such divestment shall terminate upon  the
    election of the directors at such annual meeting or adjournment thereof.

    b.   FIRST MEETING FOR ELECTION OF DIRECTORS.   At the first meeting for the
election of directors after  any accrual of the  special right of the  preferred
shareholders  to elect a majority of the  Board of Directors, as provided above,
and at any subsequent annual meeting  for the election of directors held  during
the continuance of such special right, the presence in person or by proxy of the
holders  of record of  a majority of  the outstanding shares  of Preferred Stock
without regard  to series  shall be  necessary to  constitute a  quorum for  the
election of the directors whom the preferred shareholders are entitled to elect,
and the presence in person or by proxy of the holders of record of a majority of
the outstanding shares of Common Stock shall be necessary to constitute a quorum
for  the election of the directors whom  the common shareholders are entitled to
elect. If at any such meeting there shall not be such a quorum of the  preferred
shareholders,  the meeting shall  be adjourned from time  to time without notice
other than  announcement  at the  meeting  until  such quorum  shall  have  been
obtained;  provided that,  if such  quorum shall  not have  been obtained within
ninety (90) days from the date of such meeting as originally called (or, in  the
case  of any annual meeting  held during the continuance  of such special right,
from the date fixed for such annual meeting), the presence in person or by proxy
of the holders of record of one-third of the outstanding shares of the Preferred
Stock, without regard to series, shall then be sufficient to constitute a quorum
for the election of  the directors whom such  shareholders are then entitled  to
elect.  The absence of a  quorum of the preferred shareholders  as a class or of
the common shareholders  as a class  shall not, except  as hereinafter  provided
for,  prevent or invalidate the  election by the other  class of shareholders of
the directors  whom they  are entitled  to  elect, if  the necessary  quorum  of
shareholders of such other class is present in person or represented by proxy at
any  such meeting or any adjournment thereof.  However, at the first meeting for
the

                                      J-4
<PAGE>
election of directors after  any accrual of the  special right of the  preferred
shareholders  to elect a  majority of the  Board of Directors,  the absence of a
quorum of the preferred shareholders shall prevent the election of directors  by
the  common shareholders, until a quorum  of the preferred shareholders shall be
obtained.

    c.  CUMULATIVE VOTING.  The holders of shares of stock of any class entitled
to vote at  a meeting  for the  election of directors  shall have  the right  to
cumulate their votes at such election in the manner provided by the WBCL.

    6.  SPECIAL VOTING RIGHTS OF PREFERRED STOCK.

    a.   ACT REQUIRING MAJORITY VOTE OF PREFERRED  STOCK.  So long as any of the
Preferred Stock is outstanding, the  Corporation shall not, without the  consent
(given  in  writing or  by vote  at a  meeting  duly called  for the  purpose in
accordance with the provisions of  the Bylaws) of the  holders of a majority  of
the  total number of shares of such  stock, without regard to series, present or
represented by proxy at such meeting,  at which meeting a quorum as  hereinafter
provided shall be present or represented by proxy;

        (i)   issue  any  unsecured  notes,   debentures,  or  other  securities
    representing  unsecured   indebtedness,  or   assume  any   such   unsecured
    securities,  for purposes other than  the refunding of outstanding unsecured
    securities  theretofore  issued  or  assumed  by  the  Corporation  or   the
    redemption  or other retirement of outstanding  shares of one or more series
    of the Preferred Stock, if, immediately after such issue or assumption,  the
    total  principal  amount  of  all  unsecured  notes,  debentures,  or  other
    securities representing  unsecured indebtedness  issued  or assumed  by  the
    Corporation  and then outstanding (including unsecured securities then to be
    issued or assumed) would exceed twenty percent (20%) of the aggregate of (a)
    the total principal  amount of  all bonds or  other securities  representing
    secured  indebtedness issued  or assumed by  the Corporation and  then to be
    outstanding, and (b) the capital  and surplus of the Corporation  (including
    all  earned surplus, paid-in  surplus, capital surplus,  or other surplus of
    the Corporation)  as then  to  be stated  on the  books  of account  of  the
    Corporation; or

        (ii)  merge  or  consolidate  with  or  into  any  other  corporation or
    corporations, unless  such  merger  or consolidation,  or  the  issuance  of
    assumption  of all securities to be issued or assumed in connection with any
    such  merger  or  consolidation,  shall  have  been  ordered,  approved,  or
    permitted  by the Securities and Exchange Commission under the provisions of
    the Public  Utility  Holding  Company  Act  of  1935  or  by  any  successor
    commission  or regulatory authority  of the United  States of America having
    jurisdiction in the premises;  provided that the  provisions of this  clause
    (ii)  shall not apply to a purchase  or other acquisition by the Corporation
    of the franchises or other assets of another corporation, or otherwise apply
    in any matter which does not involve a merger or consolidation.

    b.  QUORUM OF PREFERRED  STOCKHOLDERS.  For the  purpose of this Section  6,
the presence in person or by proxy of the holders or record of a majority of the
outstanding  shares  of  Preferred Stock,  without  regard to  series,  shall be
necessary to constitute a quorum; provided,  that if such quorum shall not  have
been  obtained at such meeting or at  any adjournment thereof within thirty (30)
days from the date of such meeting as originally called, the presence in  person
or  by proxy  of the  holders of  record of  one-third (1/3)  of the outstanding
shares of such  stock, without  regard to series,  shall then  be sufficient  to
constitute  a quorum; and provided further that in the absence of a quorum, such
meeting or any adjournment  thereof may be  adjourned from time  to time by  the
officer or officers of the Corporation who shall have called the meeting (but at
intervals  of  not  less than  seven  days  unless all  shareholders  present or
represented by proxy  shall agree to  a shorter interval)  without notice  other
than  announcement at  the meeting  until a  quorum as  above provided  shall be
obtained.

                                      J-5
<PAGE>
    c.  ACTS WHICH INCLUDE REDEMPTION OF PREFERRED STOCK.  No vote or consent of
the holders of any series of the Preferred Stock shall be required, however, if,
at or  prior  to  the  issue  of  any  such  securities  representing  unsecured
indebtedness,  or such consolidation, merger, or sale, provision is made for the
redemption or other retirement of all shares of such series then outstanding.

    d.  ADDITIONAL TO  OTHER VOTING REQUIREMENTS.   The provisions set forth  in
this  Section 6 are in  addition to any other vote  required by any provision of
the Articles  of Incorporation  of the  Corporation, as  amended, or  applicable
statute, and shall be so construed.

    7.   ISSUANCE IN AMOUNT OF PREFERRED STOCK.  So long as any of the Preferred
Stock is outstanding, the Corporation shall  not, without the consent (given  by
vote  at a meeting duly called for the purpose in accordance with the provisions
of the Bylaws) of  the holders of a  majority of the total  number of shares  of
such  stock  then outstanding,  without regard  to class  or series,  present or
represented by proxy at  such meeting, increase the  total authorized amount  of
Preferred  Stock (other than as  authorized by this Article  V) or authorize any
other preferred stock ranking on a parity with the Preferred Stock as to  assets
or  dividends (other  than through the  reclassification of  then authorized but
unissued shares of Preferred Stock into shares of such other preferred stock).

    8.  ISSUANCE OF STOCK PREFERRED OVER PREFERRED STOCK.  So long as any of the
Preferred Stock is outstanding, the  Corporation shall not, without the  consent
(given  by vote at a meeting duly called  for the purpose in accordance with the
provisions of the Bylaws)  of the holders of  at least sixty-six and  two-thirds
per  cent (66- 2/3%) of  the total number of  shares of Preferred Stock, without
regard to series,  then outstanding,  present or  represented by  proxy at  such
meeting,  authorize any class of stock which  shall be preferred as to assets or
dividends over the Preferred Stock; or, without the consent of the holders of at
least sixty-six and two-thirds per cent (66- 2/3%) of the total number of shares
of Preferred Stock then outstanding, given as above provided in this Section  8,
amend  the Articles of Incorporation, to change the express terms and provisions
of the Preferred Stock  in any manner substantially  prejudicial to the  holders
thereof.

    9.  EFFECTING AND VALIDATING ADDITIONAL STOCK OR SECURITIES CONVERTIBLE INTO
STOCK.  So long as any shares of Preferred Stock are outstanding, the consent of
the  holders of  at least two-thirds  (2/3) of  the Preferred Stock  at the time
outstanding, voting as a class and without regard to series, given in person  or
by  proxy, either in writing  or by vote at any  meeting called for the purpose,
shall be  necessary for  effecting or  validating the  issue of  any  additional
shares  of Preferred Stock (other  than and not exceeding  275,000 shares of the
Cumulative Preferred Stock,  $3.60 Series), or  any shares of  stock, or of  any
security  convertible into  stock, of  any class  ranking on  a parity  with the
Preferred Stock, unless

        (i) the  net  income  of  the  Corporation  (determined  as  hereinafter
    provided)  for  any twelve  consecutive calendar  months within  the fifteen
    calendar months immediately preceding the month within which the issuance of
    such additional  shares is  authorized  by the  Board  of Directors  of  the
    Corporation  shall have been in the aggregate not less than one and one-half
    times the  sum of  the interest  requirements for  one year  on all  of  the
    indebtedness  of  the Corporation  to  be outstanding  at  the date  of such
    proposed issue and the full dividend requirements for one year on all shares
    of Preferred Stock, and all  other stock, if any, ranking  prior to or on  a
    parity  with the  Preferred Stock,  to be  outstanding at  the date  of such
    proposed issue,  including  the  shares  then  proposed  to  be  issued  but
    excluding  any such indebtedness and any  such shares proposed to be retired
    in connection  with such  proposed issue.  For purposes  of calculating  the
    dividend  requirements for  one year applicable  to any  series of Preferred
    Stock proposed to be issued  which will have dividends determined  according
    to an adjustable, floating or variable rate, the dividend rate used shall be
    the  higher of (A) the dividend rate  applicable to such series of Preferred
    Stock on the  date of  such calculation, or  (B) the  average dividend  rate
    payable on all series of Preferred Stock outstanding during the twelve month
    period  immediately preceding the date of  such calculation. For purposes of
    calculating the dividend or interest requirements for one year applicable to
    any series of  Preferred Stock or  indebtedness outstanding at  the date  of
    such proposed issue and

                                      J-6
<PAGE>
    having dividends or interest determined according to an adjustable, floating
    or  variable rate, the dividend or interest  rate used shall be: (A) if such
    series of Preferred Stock or indebtedness has been outstanding for at  least
    twelve months, the actual amount of dividends or interest paid on account of
    such  series of Preferred Stock or  indebtedness for the twelve month period
    immediately preceding the date of such calculation, or (B) if such series of
    Preferred Stock or indebtedness  has been outstanding  for less than  twelve
    months,  the higher of (1) the dividend  or interest rate applicable to such
    series of Preferred Stock or indebtedness on the date of such calculation or
    (2) the average dividend or interest rate payable on all series of Preferred
    Stock or indebtedness outstanding during the twelve month period immediately
    preceding the date of such calculation. "Net income" for any period for  the
    purpose  of this Section 9 shall be computed  by adding to the net income of
    the Corporation for  said period,  determined in  accordance with  generally
    accepted  accounting  practices,  as  adjusted by  action  of  the  Board of
    Directors of the  Corporation as hereinafter  provided, the amount  deducted
    for  interest  before  arriving  at  such  net  income  (adjusted  as  above
    provided). In determining  such net income  for any period,  there shall  be
    deducted  the provisions for depreciation and  depletion as recorded on such
    books or the minimum  amount required therefor under  the provisions of  any
    then  existing trust  indenture or  supplements thereto  of the Corporation,
    whichever is larger. In the determination  of such net income, the Board  of
    Directors  of the Corporation  may, in the exercise  of due discretion, make
    adjustments by way of increase or decrease in such net income to give effect
    to changes therein resulting  from any acquisition of  properties or to  any
    redemption,  acquisition, purchase, sale,  or exchange of  securities by the
    Corporation either prior to the issuance  of any shares of Preferred  Stock,
    or  stock,  or  securities  convertible  into  stock,  ranking  on  a parity
    therewith then to be issued or in connection therewith; and

        (ii) the aggregate of the capital  of the Corporation applicable to  all
    stock  of any class ranking junior to  the Preferred Stock, plus the surplus
    of the Corporation, shall be not less than the aggregate amount payable upon
    involuntary liquidation, dissolution, or  winding up of  the affairs of  the
    Corporation  to the  holders of  all shares  of Preferred  Stock and  of any
    shares of stock of any class ranking on a parity therewith to be outstanding
    immediately after such proposed issue,  excluding from such computation  all
    indebtedness and stock to be retired through such proposed issue. No portion
    of  the  surplus  of  the  Corporation  utilized  to  satisfy  the foregoing
    requirements shall be available for dividends (other than dividends  payable
    in  stock  of any  class ranking  junior  to the  Preferred Stock)  or other
    distributions upon or in  respect of shares of  stock of the Corporation  of
    any  class ranking junior to the Preferred  Stock for the purchase of shares
    of such junior  stock until such  number of additional  shares of  Preferred
    Stock or of stock, or securities convertible into stock, ranking on a parity
    with  the Preferred Stocks are  retired or until and  to the extent that the
    capital applicable to such junior stock shall have been increased.

    10.  DIVIDENDS  ON COMMON STOCK.   So long  as any shares  of the  Preferred
Stock are outstanding, the Corporation shall not pay any dividends on its Common
Stock (other than dividends payable in Common Stock) or make any distribution on
or  purchase or otherwise acquire  for value any of  its Common Stock (each such
payment, distribution, purchase and/or acquisition being herein referred to as a
"Common Stock  dividend"),  except to  the  extent permitted  by  the  following
provisions of this Section 10.

    a.   No Common Stock dividend shall be  declared or paid in an amount which,
together with all other  Common Stock dividends declared  in the year ending  on
(and including) the date of the declaration of such Common Stock dividend, would
in  the  aggregate  exceed  fifty  per  cent (50%)  of  the  net  income  of the
Corporation for the period consisting of the twelve consecutive calendar  months
ending  on  the  last  day  of the  second  calendar  month  next  preceding the
declaration of such Common Stock dividend after deducting from such net  income,
dividends accruing on any preferred stock of the Corporation during such period,
if   at  the  end  of  such  period   the  ratio  (herein  referred  to  as  the
"capitalization ratio") of the sum of (1) the capital represented by the  Common
Stock (including

                                      J-7
<PAGE>
premiums  on capital stock) and (2) the surplus accounts, of the Corporation, to
the sum  of  (1)  the  total  capital and  (2)  the  surplus  accounts,  of  the
Corporation (after adjustment of the surplus accounts to reflect payment of such
Common Stock dividend) would be less than twenty per cent (20%).

    b.   If such  capitalization ratio, determined as  aforesaid shall be twenty
per cent (20%) or more, but less than twenty-five per cent (25%) no Common Stock
dividend shall be declared or paid in  an amount which, together with all  other
Common  Stock dividends declared in the year  ending on [and including] the date
of the declaration of such Common Stock dividend, would in the aggregate  exceed
seventy-five  per cent (75%) of the net income of the Corporation for the period
consisting of the twelve consecutive calendar  months ending on the last day  of
the  second calendar month  next preceding the declaration  of such Common Stock
dividend after  deducting  from  such  net income,  dividends  accruing  on  any
preferred stock of the Corporation during such period; and

    c.    If such  capitalization ratio,  determined as  aforesaid, shall  be in
excess of twenty-five per cent (25%), no Common Stock dividend shall be declared
or paid which would  reduce such capitalization ratio  to less than  twenty-five
per  cent (25%) except to the extent  permitted by the next preceding paragraphs
(a) and (b) hereof. For the purpose of this condition:

        (i) The total capital of the  Corporation shall be deemed to consist  of
    the aggregate of (1) the principal amount of all outstanding indebtedness of
    the  Corporation maturing more than one year after the date of issue thereof
    and (2) the par value of or the stated capital applicable to all outstanding
    capital stock (including premiums  on capital stock) of  all classes of  the
    Corporation.  All indebtedness  and capital  stock owned  by the Corporation
    shall be excluded in  determining total capital.  Surplus accounts shall  be
    deemed  to include all earned surplus,  paid-in surplus, capital surplus, or
    any other surplus of the Corporation.

        (ii) Such surplus accounts upon which capitalization ratios are computed
    shall be adjusted to eliminate (1) the amount, if any, by which fifteen  per
    cent (15%) of the gross operating revenues of the Corporation (calculated in
    the  manner provided  in the covenants  relating to payment  of Common Stock
    dividends embodied in  the indentures and  supplemental indentures  securing
    the  mortgage bonds of the  Corporation) for the entire  period from July 1,
    1946, to the end of the second calendar month immediately preceding the date
    of the proposed payment of Common  Stock dividends exceeds the total  amount
    expended  by the Corporation during such  period for maintenance and repairs
    and the  total provision  made by  the Corporation  during such  period  for
    depreciation,  all as  shown by  the books of  the Corporation,  and (2) any
    amounts on the books of the Corporation known or estimated, if not known, to
    represent the excess, if any, of  recorded value over original cost of  used
    and  useful utility plant and other property,  and any item set forth on the
    asset side of the balance sheet of the Corporation as a result of accounting
    convention, such as  unamortized debt  discount and  expense, capital  stock
    discount  and  expense, and  the  excess, if  any,  of the  aggregate amount
    payable on  involuntary  dissolution,  liquidation, or  winding  up  of  the
    Corporation  upon all  outstanding shares of  preferred stock  of all series
    over the  aggregate stated  or par  value of  such shares,  unless any  such
    amount  or item, as the case may be, is being amortized or is being provided
    for by a reserve; and

       (iii) In computing net income of the Corporation applicable to the Common
    Stock of the Corporation for any  particular twelve (12) months' period  for
    the  purposes  of this  condition, operating  expenses, among  other things,
    shall include the  greater of (1)  the provision for  depreciation for  such
    period  as recorded  on the books  of the  Corporation or (2)  the amount by
    which  fifteen  percent  (15%)  of  the  gross  operating  revenues  of  the
    Corporation  for such period (calculated in the manner provided in the above
    mentioned covenants relating to payment  of Common Stock dividends)  exceeds
    the  total  amount  expended  by the  Corporation  during  such  periods for
    maintenance and repairs as shown by the books of the Corporation.

    11.    ACCEPTANCE  OF  SHARES.    In  consideration  of  the  issue  by  the
Corporation, and the acceptance by the holders thereof, of shares of the capital
stock  of the Corporation, each and every present and future holder of shares of
the Preferred Stock, the Common Stock  and of any stock hereafter authorized  of
the  Corporation  shall be  conclusively deemed,  by  acquiring or  holding such
shares, to have

expressly consented to all and singular the terms and provisions of this Article
V and to have agreed that the voting rights of such holder and the  restrictions
and qualifications thereof shall be as set forth in this Article.

    12.   OUTSTANDING STOCK OR  EVIDENCE OF INDEBTEDNESS.   No share of stock or
evidence of indebtedness shall  be deemed to be  "outstanding," as that term  is
used in this Article V, if, prior to or concurrently with the event in reference
to which a determination as to the amount thereof outstanding is to be made, the
requisite  funds for the redemption thereof shall be deposited in trust for that
purpose and the requisite  notice for the redemption  thereof shall be given  or
the  depositary of  such funds shall  be irrevocably authorized  and directed to
give or complete such notice of redemption.

    13.  RIGHT OF UNISSUED STOCK OR OTHER SECURITIES.  No holder of any stock of
the Corporation shall be entitled, as of right, to purchase or subscribe for any
part of any unissued shares  of stock of the  Corporation or for any  additional
shares  of stock,  of any  class or  series, which  may at  any time  be issued,
whether now or hereafter authorized, or for any rights, options, or warrants  to
purchase  or  receive  shares  of  stock  or  for  any  bonds,  certificates  of
indebtedness, debentures, or other securities convertible into shares of  stock,
or  any class  or series  thereof; but any  such unissued  or additional shares,
rights, options, or warrants or  convertible securities of the Corporation  may,
from  time to time, be issued and disposed  of by the Board of Directors to such
persons, firms, corporations, or associations, and upon such terms, as the Board
of Directors  may,  in its  discretion,  determine, without  offering  any  part
thereof  to any  shareholders of  any class  or series  then of  record; and any
shares, rights, options or warrants or convertible securities which the Board of
Directors may at any  time determine to offer  to shareholders for  subscription
may be offered to holders of shares of any class or series at the time existing,
to  the exclusion of holders of shares of  any or all other classes or series at
the time  existing,  in  each  case  as the  Board  of  Directors  may,  in  its
discretion, determine.

    i.  CUMULATIVE PREFERRED STOCK, ADJUSTABLE RATE SERIES A.

        (i) There  be  and there  hereby  is  created from  the  authorized  and
    unallocated  shares  of Cumulative  Preferred Stock  of  the Company,  a new
    series of  Cumulative  Preferred  Stock  of  the  Company  which  is  hereby
    designated  "Cumulative Preferred Stock,  Adjustable Rate Series  A" and the
    number of shares  constituting said new  series is hereby  fixed at  300,000
    shares.

        (ii)  The dividend rate of  the shares of said  new series of Cumulative
    Preferred Stock is  hereby fixed  at: (A) 6.15%  per annum  for the  initial
    dividend  period from  and including the  date of  original issuance through
    June 30, 1986 and (B) the Applicable Rate, as hereinafter defined, from time
    to time in effect,  for each subsequent dividend  period; dividends on  said
    shares,  when and as declared by the Board of Directors, shall be payable on
    the 15th day  of January,  April, July  and October  for the  quarter-yearly
    period  ending with  the last  day of the  preceding month;  except that the
    dividend period for the first such dividend shall begin with and include the
    date of  original issuance;  the dividends  payable on  said new  series  of
    Cumulative  Preferred Stock  for the period  from and including  the date of
    original issuance of said  new series of Cumulative  Preferred Stock to  and
    including  June  30, 1986  and for  any  period less  than a  full quarterly
    dividend period shall be computed on the  basis of a 360-day year of  twelve
    30-day  months and the actual number of days elapsed in the period for which
    the dividends are  payable; the  dividends payable for  each full  quarterly
    dividend period commencing after June 30, 1986 shall be computed by dividing
    the Applicable Rate for such dividend period by four (rounded to the nearest
    one-hundredth  of a percent) and applying such computed rate against the par
    value per share of said new series of Cumulative Preferred Stock.

    The Applicable Rate with respect to each dividend period will be  calculated
as  promptly as practicable  by the Company according  to the appropriate method
described herein. The Company  will cause notice of  such Applicable Rate to  be
enclosed  with, or  mailed concurrently with,  the dividend  payment checks next
mailed to  the holders  of shares  of said  new series  of Cumulative  Preferred
Stock.

    APPLICABLE   RATE.    Except  as  provided  below  in  this  paragraph,  the
"Applicable Rate" for any dividend  period will be equal  to 76% of the  highest
of:  (A) the Treasury Bill Rate, (B) the Ten Year Constant Maturity Rate and (C)
the  Thirty  Year   Constant  Maturity  Rate   (each  as  hereinafter   defined)

                                      J-13
<PAGE>
for such dividend period. If the Company determines, in good faith, that for any
reason  one or  more of (A)  the Treasury Bill  Rate, (B) the  Ten Year Constant
Maturity Rate,  and  (C)  the  Thirty Year  Constant  Maturity  Rate  cannot  be
determined  for any dividend period, then  the Applicable Rate for such dividend
period shall  be  based  on  the  higher of  whichever  such  rates  can  be  so
determined.  If  the Company  determines, in  good faith,  that neither  (A) the
Treasury Bill Rate, (B) the Ten Year  Constant Maturity Rate nor (C) the  Thirty
Year  Constant Maturity Rate can be determined for any dividend period, then the
Applicable Rate in effect for the  preceding dividend period shall be  continued
for  such dividend period. Notwithstanding anything  to the contrary herein, the
Applicable Rate for  any dividend  shall not  be less  than 5.50%  per annum  or
greater than 10.25% per annum.

    TREASURY  BILL  RATE.   Except  as  provided  below in  this  paragraph, the
"Treasury Bill Rate" for each dividend period will be the arithmetic average  of
the  two most recently weekly per annum market discount rates (or the one weekly
per annum market discount rate, if only one such rate shall be published  during
the  relevant Calendar Period,  as defined below)  for three-month U.S. Treasury
Bills, published by the  Board of Governors of  the Federal Reserve System  (the
"Federal  Reserve Board")  during the Calendar  Period immediately  prior to the
last ten calendar days of the June, September, December or March, next preceding
the dividend period for which the dividend rate on the shares of the new  series
of  Cumulative Preferred Stock is being determined. If the Federal Reserve Board
does not  publish such  a weekly  per  annum market  discount rate  during  such
Calendar  Period, then the Treasury Bill Rate  for such dividend period shall be
the arithmetic average of the two  most recent weekly per annum market  discount
rates  (or the one weekly per annum market  discount rate, if only one such rate
shall be published during  such Calendar Period)  for three-month U.S.  Treasury
Bills,  published during such Calendar Period by  any Federal Reserve Bank or by
any U.S. Government department or agency selected by the Company. If a per annum
market discount rate for three-month U.S. Treasury Bills shall not be  published
by  the Federal  Reserve Board  or by any  Federal Reserve  Bank or  by any U.S.
Government department or agency during  such Calendar Period, then the  Treasury
Bill  Rate for such dividend  period shall be the  arithmetic average of the two
most recent weekly per annum market discount rates (or the one weekly per  annum
market  discount rate,  if only  one such  rate shall  be published  during such
Calendar Period) for all  of the U.S. Treasury  Bills then having maturities  of
not  less than 80  days nor more  than 100 days,  published during such Calendar
Period by the Federal Reserve Board or,  if the Federal Reserve Board shall  not
publish  such  rates, by  any Federal  Reserve  Bank or  by any  U.S. Government
department or agency selected by the Company. If the Company determines, in good
faith, that no  such U.S. Treasury  Bill rates are  published as provided  above
during  such  Calendar Period,  then the  Treasury Bill  Rate for  such dividend
period shall be the  arithmetic average of the  per annum market discount  rates
based  upon the closing bids during such  Calendar Period for each of the issues
of marketable non-interest bearing U.S.  Treasury securities with a maturity  of
not  less  than 80  days nor  more  than 100  days from  the  date of  each such
quotation, as chosen and quoted  daily, for each business  day in New York  City
(or  less frequently if  daily quotations shall not  be generally available), to
the Company by at least three  recognized dealers in U.S. Government  securities
selected  by the Company. If the Company determines, in good faith, that for any
reason the Company  cannot determine  the Treasury  Bill Rate  for any  dividend
period as provided above in this paragraph, then the Treasury Bill Rate for such
dividend period shall be the arithmetic average of the per annum market discount
rates  based upon the closing  bids during such Calendar  Period for each of the
issues of marketable interest-bearing U.S.  Treasury securities with a  maturity
of  not less  than 80 days  nor more than  100 days  from the date  of each such
quotation, as chosen and quoted daily for each business day in New York City (or
less frequently if  daily quotations shall  not be generally  available) to  the
Company  by  at least  three recognized  dealers  in U.S.  Government securities
selected by the Company.  The weekly per annum  market discount rate for  three-
month U.S. Treasury Bills shall be the secondary market rate.

    TEN  YEAR  CONSTANT  MATURITY  RATE.    Except  as  provided  below  in this
paragraph, the "Ten Year Constant Maturity Rate" for each dividend period  shall
be  the arithmetic  average of  the two  most recent  weekly per  annum Ten Year
Average Yields as  hereinafter defined  (or the one  weekly per  annum Ten  Year
Average  Yield, if only  one such Yield  shall be published  during the relevant
Calendar

                                      J-14
<PAGE>
Period as defined  below), published  by the  Federal Reserve  Board during  the
Calendar  Period immediately prior  to the last  ten calendar days  of the June,
September, December or March, next preceding  the dividend period for which  the
dividend  rate on the shares of the  new series of Cumulative Preferred Stock is
being determined. If the  Federal Reserve Board does  not publish such a  weekly
per  annum Ten Year Average Yield during such Calendar Period, then the Ten Year
Constant Maturity Rate for such dividend period shall be the arithmetic  average
of  the two  most recent weekly  per annum Ten  Year Average Yields  (or the one
weekly per  annum Ten  Year  Average Yield,  if only  one  such Yield  shall  be
published during such Calendar Period), published during such Calendar Period by
any Federal Reserve Bank or by any U.S. Government department or agency selected
by  the Company. If a per annum Ten Year Average Yield shall not be published by
the Federal  Reserve  Board or  by  any Federal  Reserve  Bank or  by  any  U.S.
Government  department or agency during such  Calendar Period, then the Ten Year
Constant Maturity Rate for such dividend period shall be the arithmetic  average
of  the two most recent weekly per annum  average yields to maturity (or the one
weekly per annum  average yield to  maturity, if  only one such  yield shall  be
published during such Calendar Period) for all of the actively traded marketable
U.S.  Treasury fixed interest rate securities (other than Special Securities, as
defined below) then having maturities of not less than eight years nor more than
twelve years, published during such Calendar Period by the Federal Reserve Board
or, if the Federal Reserve Board shall  not publish such yields, by any  Federal
Reserve  Bank or  by any  U.S. Government department  or agency  selected by the
Company. If the Company determines in good faith that for any reason the Company
cannot determine the Ten Year Constant Maturity Rate for any dividend period  as
provided  above in this paragraph, then the  Ten Year Constant Maturity Rate for
such dividend period shall  be the arithmetic average  of the per annum  average
yields  to maturity based upon the closing  bids during such Calendar Period for
each of the issues  of actively traded marketable  U.S. Treasury fixed  interest
rate  securities (other than Special Securities)  with a final maturity date not
less than eight  years nor more  than twelve years  from the date  of each  such
quotation, as chosen and quoted daily for each business day in New York City (or
less  frequently if  daily quotations shall  not be generally  available) to the
Company by  at least  three  recognized dealers  in U.S.  Government  securities
selected by the Company.

    THIRTY  YEAR  CONSTANT MATURITY  RATE.   Except  as  provided below  in this
paragraph, the "Thirty  Year Constant  Maturity Rate" for  each dividend  period
shall  be the arithmetic average of the  two most recent weekly per annum Thirty
Year Average Yields as hereinafter defined  (or the one weekly per annum  Thirty
Year  Average  Yield, if  only  one such  Yield  shall be  published  during the
relevant Calendar Period  as defined  below), published by  the Federal  Reserve
Board during the Calendar Period immediately prior to the last ten calendar days
of  the June, September,  December or March, next  preceding the dividend period
for which  the dividend  rate on  the shares  of the  new series  of  Cumulative
Preferred  Stock  is being  determined. If  the Federal  Reserve Board  does not
publish such a weekly per annum  Thirty Year Average Yield during such  Calendar
Period,  then the  Thirty Year Constant  Maturity Rate for  such dividend period
shall be the arithmetic average of the  two most recent weekly per annum  Thirty
Year  Average Yields (or the one weekly  per annum Thirty Year Average Yield, if
only one such Yield shall be  published during such Calendar Period),  published
during  such  Calendar  Period  by  any Federal  Reserve  Bank  or  by  any U.S.
Government department or agency selected by  the Company. If a per annum  Thirty
Year Average Yield shall not be published by the Federal Reserve Board or by any
Federal  Reserve Bank or by any U.S. Government department or agency during such
Calendar Period, then the Thirty Year  Constant Maturity Rate for such  dividend
period  shall be the arithmetic average of  the two most recent weekly per annum
average yields  to  maturity (or  the  one weekly  per  annum average  yield  to
maturity, if only one such Yield shall be published during such Calendar Period)
for  all of  the actively  traded marketable  U.S. Treasury  fixed interest rate
securities (other than Special  Securities) than having  maturities of not  less
than  twenty-eight nor  more than thirty  years, published  during such Calendar
Period by the Federal Reserve Board or,  if the Federal Reserve Board shall  not
publish  such yields,  by any  Federal Reserve  Bank or  by any  U.S. Government
department or agency selected by the Company. If the Company determines in  good
faith  that for any reason the Company cannot determine the Thirty Year Constant
Maturity Rate for

                                      J-15
<PAGE>
any dividend period as  provided above in this  paragraph, then the Thirty  Year
Constant  Maturity Rate for such dividend period shall be the arithmetic average
of the per annum average yields to  maturity based upon the closing bids  during
such  Calendar Period for each of the  issues of actively traded marketable U.S.
Treasury fixed interest rate securities  (other than Special Securities) with  a
final  maturity date not less than twenty-eight years nor more than thirty years
from the  date of  each such  quotation, as  chosen and  quoted daily  for  each
business  day in New York City (or less frequently if daily quotations shall not
be generally available) to the Company  by at least three recognized dealers  in
U.S. Government securities selected by the Company.

Preferred Stock are hereby fixed at (A) $106.15 per share in case of  redemption
on  or prior  to June  30, 1991;  (B) $103.00  per share  in case  of redemption

series of Cumulative Preferred Stock to be redeemed began to accrue to the  date
fixed  for redemption  thereof, less  the amount  of dividends  theretofore paid
thereon; provided, however,  that the shares  of said new  series of  Cumulative
Preferred  Stock shall not be redeemable,  directly or indirectly, prior to July
1, 1991 with  the proceeds  from borrowed  funds, or  from the  issuance of  any
preferred  stock ranking  prior to or  on a parity  with the shares  of said new
series of Cumulative Preferred Stock as  to dividends or on liquidation,  having
an effective cost to the Company, computed in accordance with generally accepted
financial practice, of less than 6.15% per annum.

   (iv)  The amount which the shares of  said new series of Cumulative Preferred
Stock are  entitled  to receive  in  preference to  the  Common Stock  upon  any
distribution  of assets, other  than by dividends from  net earnings or surplus,
upon voluntary liquidation or dissolution of the Company is hereby fixed as  the
then  redemption price,  plus an amount  equal to all  dividends accumulated and
unpaid thereon.

    j.  CUMULATIVE PREFERRED STOCK, ADJUSTABLE RATE SERIES B.

    (i) There be and there hereby is created from the authorized and  unallotted
shares  of Cumulative Preferred Stock of the Company, a new series of Cumulative
Preferred Stock of the Company which is hereby designated "Cumulative  Preferred
Stock, Adjustable Rate Series B" and the number
of shares constituting said new series is hereby fixed at 650,000 shares.

    (ii)  The  dividend rate  of the  shares  of said  new series  of Cumulative
Preferred Stock is hereby fixed at: (A) 6.80% per annum for the initial dividend
period from and including  the date of original  issuance through June 30,  1987
and  (B)  the Applicable  Rate, as  hereinafter  defined, from  time to  time in
effect, for each subsequent dividend period; dividends on said shares, when  and
as  declared by  the Board  of Directors, shall  be payable  on the  15th day of
January, April, July and  October of each year  for the quarterly period  ending
with  the last day of  the preceding month; except  that the dividend period for
the first  such dividend  shall begin  with  and include  the date  of  original
issuance; the dividends payable on said new series of Cumulative Preferred Stock
for  the period  from and including  the date  of original issuance  of said new
series of Cumulative Preferred Stock to and including June 30, 1987 and for  any
period less than a full quarterly dividend period shall be computed on the basis
of  a 360-day year of twelve 30-day months and the actual number of days elapsed
in the period

                                      J-16
<PAGE>
for which  the  dividends are  payable;  the  dividends payable  for  each  full
quarterly  dividend period commencing  after June 30, 1987  shall be computed by
dividing the Applicable Rate  for such dividend period  by four (rounded to  the
nearest  one-hundredth of a percent) and applying such computed rate against the
par value per share of said new series of Cumulative Preferred Stock.

    The Applicable Rate with respect to each dividend period will be  calculated
as  promptly as practicable  by the Company according  to the appropriate method
described herein. The Company  will cause notice of  such Applicable Rate to  be
enclosed  with, or  mailed concurrently with,  the dividend  payment checks next
mailed to  the holders  of shares  of said  new series  of Cumulative  Preferred
Stock.

    APPLICABLE   RATE.    Except  as  provided  below  in  this  paragraph,  the
"Applicable Rate" for any dividend  period will be equal  to 78% of the  highest
of:  (A) the Treasury Bill Rate, (B) the Ten Year Constant Maturity Rate and (C)
the Thirty Year Constant  Maturity Rate (each as  hereinafter defined) for  such
dividend  period. If the Company determines, in  good faith, that for any reason
one or more of (A)  the Treasury Bill Rate, (B)  the Ten Year Constant  Maturity
Rate,  and (C) the Thirty  Year Constant Maturity Rate  cannot be determined for
any dividend period, then the Applicable Rate for such dividend period shall  be
based on the higher of whichever such rates can be so determined. If the Company
determines,  in good faith, that neither (A) the Treasury Bill Rate, (B) the Ten
Year Constant Maturity Rate nor (C)  the Thirty Year Constant Maturity Rate  can
be  determined for any dividend  period, then the Applicable  Rate in effect for
the preceding  dividend period  shall  be continued  for such  dividend  period.
Notwithstanding  anything to  the contrary herein,  the Applicable  Rate for any
dividend period shall not be  less than 5.50% per  annum or greater than  11.00%
per annum.

    TREASURY  BILL  RATE.   Except  as  provided  below in  this  paragraph, the
"Treasury Bill Rate" for each dividend period will be the arithmetic average  of
the  two most recent weekly  per annum market discount  rates (or the one weekly
per annum market discount rate, if only one such rate shall be published  during
the  relevant Calendar Period,  as defined below)  for three-month U.S. Treasury
Bills, published by the  Board of Governors of  the Federal Reserve System  (the
"Federal  Reserve Board")  during the Calendar  Period immediately  prior to the
last ten calendar days of the June, September, December or March, next preceding
the dividend period for which the dividend rate on the shares of the new  series
of  Cumulative Preferred Stock is being determined. If the Federal Reserve Board
does not  publish such  a weekly  per  annum market  discount rate  during  such
Calendar  Period, then the Treasury Bill Rate  for such dividend period shall be
the arithmetic average of the two  most recent weekly per annum market  discount
rates  (or the one weekly per annum market  discount rate, if only one such rate
shall be published during  such Calendar Period)  for three-month U.S.  Treasury
Bills,  published during such Calendar Period by  any Federal Reserve Bank or by
any U.S. Government department or agency selected by the Company. If a per annum
market discount rate for three-month U.S. Treasury Bills shall not be  published
by  the Federal  Reserve Board  or by any  Federal Reserve  Bank or  by any U.S.
Government department or agency during  such Calendar Period, then the  Treasury
Bill  Rate for such dividend  period shall be the  arithmetic average of the two
most recent weekly per annum market discount rates (or the one weekly per  annum
market  discount rate,  if only  one such  rate shall  be published  during such
Calendar Period) for all  of the U.S. Treasury  Bills then having maturities  of
not  less than 80  days nor more  than 100 days,  published during such Calendar
Period by the Federal Reserve Board or,  if the Federal Reserve Board shall  not
publish  such  rates, by  any Federal  Reserve  Bank or  by any  U.S. Government
department or agency selected by the Company. If the Company determines, in good
faith, that no  such U.S. Treasury  Bill rates are  published as provided  above
during  such  Calendar Period,  then the  Treasury Bill  Rate for  such dividend
period shall be the  arithmetic average of the  per annum market discount  rates
based  upon the closing bids during such  Calendar Period for each of the issues
of marketable non-interest bearing U.S.  Treasury securities with a maturity  of
not  less  than 80  days nor  more  than 100  days from  the  date of  each such
quotation, as chosen and quoted  daily, for each business  day in New York  City
(or  less frequently if  daily quotations shall not  be generally available), to
the Company by at least three  recognized dealers in U.S. Government  securities

                                      J-17

provided  above in this paragraph, then the Treasury Bill Rate for such dividend
period shall be the  arithmetic average of the  per annum market discount  rates
based  upon the closing bids during such  Calendar Period for each of the issues
of marketable interest-bearing U.S. Treasury  securities with a maturity of  not
less  than 80 days nor more than 100  days from the date of each such quotation,
as chosen and  quoted daily  for each  business day in  New York  City (or  less
frequently  if daily quotations shall not be generally available) to the Company
by at least three recognized dealers  in U.S. Government securities selected  by
the  Company. The  weekly per  annum market  discount rate  for three-month U.S.
Treasury Bills shall be the secondary market rate.

    TEN YEAR  CONSTANT  MATURITY  RATE.    Except  as  provided  below  in  this
paragraph,  the "Ten Year Constant Maturity Rate" for each dividend period shall
be the arithmetic  average of  the two  most recent  weekly per  annum Ten  Year
Average  Yields as  hereinafter defined  (or the one  weekly per  annum Ten Year
Average Yield, if  only one such  Yield shall be  published during the  relevant
Calendar Period as defined below), published by the Federal Reserve Board during
the Calendar Period immediately prior to the last ten calendar days of the June,
September,  December or March  next preceding the dividend  period for which the
dividend rate on the shares of the  new series of Cumulative Preferred Stock  is
being  determined. If the Federal  Reserve Board does not  publish such a weekly
per annum Ten Year Average Yield during such Calendar Period, then the Ten  Year
Constant  Maturity Rate for such dividend period shall be the arithmetic average
of the two  most recent weekly  per annum Ten  Year Average Yields  (or the  one
weekly  per  annum Ten  Year  Average Yield,  if only  one  such Yield  shall be
published during such Calendar Period), published during such Calendar Period by
any Federal Reserve Bank or by any U.S. Government department or agency selected
by the Company. If a per annum Ten Year Average Yield shall not be published  by
the  Federal  Reserve  Board or  by  any Federal  Reserve  Bank or  by  any U.S.
Government department or agency during such  Calendar Period, then the Ten  Year
Constant  Maturity Rate for such dividend period shall be the arithmetic average
of the two most recent weekly per  annum average yields to maturity (or the  one
weekly  per annum  average yield to  maturity, if  only one such  yield shall be
published during such Calendar Period) for all of the actively traded marketable
U.S. Treasury fixed interest rate securities (other than Special Securities,  as
defined below) then having maturities of not less than eight years nor more than
twelve years, published during such Calendar Period by the Federal Reserve Board
or,  if the Federal Reserve Board shall  not publish such yields, by any Federal
Reserve Bank or  by any  U.S. Government department  or agency  selected by  the
Company. If the Company determines in good faith that for any reason the Company
cannot  determine the Ten Year Constant Maturity Rate for any dividend period as
provided above in this paragraph, then  the Ten Year Constant Maturity Rate  for
such  dividend period shall be  the arithmetic average of  the per annum average
yields to maturity based upon the  closing bids during such Calendar Period  for
each  of the issues  of actively traded marketable  U.S. Treasury fixed interest
rate securities (other than Special Securities)  with a final maturity date  not
less  than eight  years nor more  than twelve years  from the date  of each such
quotation, as chosen and quoted daily for each business day in New York City (or
less frequently if  daily quotations shall  not be generally  available) to  the
Company  by  at least  three recognized  dealers  in U.S.  Government securities
selected by the Company.

    THIRTY YEAR  CONSTANT MATURITY  RATE.   Except  as  provided below  in  this
paragraph,  the "Thirty  Year Constant Maturity  Rate" for  each dividend period
shall be the arithmetic average of the  two most recent weekly per annum  Thirty
Year  Average Yields as hereinafter defined (or  the one weekly per annum Thirty
Year Average  Yield,  if only  one  such Yield  shall  be published  during  the
relevant  Calendar Period  as defined below),  published by  the Federal Reserve
Board during the Calendar Period immediately prior to the last ten calendar days
of the June, September, December or March next preceding the dividend period for
which the dividend rate on the shares of the new series of Cumulative  Preferred
Stock  is being determined. If the Federal Reserve Board does not publish such a
weekly per annum Thirty Year Average Yield during such Calendar Period, then the
Thirty Year  Constant  Maturity Rate  for  such  dividend period  shall  be  the
arithmetic  average of the two most recent  weekly per annum Thirty Year Average
Yields (or the one weekly per annum Thirty Year Average Yield, if only one  such
Yield   shall   be   published   during   such   Calendar   Period),   published

                                      J-18
<PAGE>
during such  Calendar  Period  by  any  Federal Reserve  Bank  or  by  any  U.S.
Government  department or agency selected by the  Company. If a per annum Thirty
Year Average Yield shall not be published by the Federal Reserve Board or by any
Federal Reserve Bank or by any U.S. Government department or agency during  such
Calendar  Period, then the Thirty Year  Constant Maturity Rate for such dividend
period shall be the arithmetic average of  the two most recent weekly per  annum
average  yields  to maturity  (or  the one  weekly  per annum  average  yield to
maturity, if only one such Yield shall be published during such Calendar Period)
for all of  the actively  traded marketable  U.S. Treasury  fixed interest  rate
securities  (other than Special  Securities) then having  maturities of not less
than twenty-eight nor  more than  thirty years, published  during such  Calendar
Period  by the Federal Reserve Board or,  if the Federal Reserve Board shall not
publish such  yields, by  any Federal  Reserve Bank  or by  any U.S.  Government
department  or agency selected by the Company. If the Company determines in good
faith that for any reason the Company cannot determine the Thirty Year  Constant
Maturity  Rate for any dividend period as provided above in this paragraph, then
the Thirty Year  Constant Maturity Rate  for such dividend  period shall be  the
arithmetic  average of the per  annum average yields to  maturity based upon the
closing bids during  such Calendar  Period for each  of the  issues of  actively
traded  marketable  U.S. Treasury  fixed  interest rate  securities  (other than
Special Securities) with a final maturity date not less than twenty-eight  years
nor  more than thirty years from the date  of each such quotation, as chosen and
quoted daily for each business day in New York City (or less frequently if daily
quotations shall not be  generally available) to the  Company by at least  three
recognized dealers in U.S. Government securities selected by the Company.

and employees  of  the Company  and  its  Affiliates. Among  other  things,  the

        (c)   to determine the number of shares of Common Stock to be covered by
    each Award granted hereunder;

        (d)   to  determine  the  terms and  conditions  of  any  Award  granted
    hereunder  (including,  but not  limited to,  the  option price  (subject to
    Section 5(a)), any vesting condition,  restriction or limitation (which  may
    be  related  to  the performance  of  the  participant, the  Company  or any
    Affiliate) and any vesting acceleration  or forfeiture waiver regarding  any
    Award and the shares of Common Stock relating thereto, based on such factors
    as the Committee shall determine;

        (e)   to modify, amend or adjust  the terms and conditions of any Award,
    at any time or from time to  time, including but not limited to  Performance

    amount payable to a designated Covered Employee with respect to a particular
    award upon the satisfaction of applicable Performance Goals;

        (f)  to  determine to what  extent and under  what circumstances  Common

    and

        (g)  to determine  under what circumstances an  Award may be settled  in
    cash or Common Stock under Sections 5(j) and 8(b)(i).

    The  Committee  shall have  the authority  to adopt,  alter and  repeal such
administrative rules, guidelines and  practices governing the  Plan as it  shall
from  time to time deem advisable, to  interpret the terms and provisions of the
Plan and any Award  issued under the Plan  (and any agreement relating  thereto)
and to otherwise supervise the administration of the Plan.

    The  Committee may  act only by  a majority  of its members  then in office,
except that the members thereof  may (i) delegate to  an officer of the  Company
the  authority to make decisions  pursuant to paragraphs (c),  (f), (g), (h) and

any officer of the  Company to execute  and deliver documents  on behalf of  the

binding on  all persons,  including  the Company  and  its Affiliates  and  Plan
participants.

    Section 3.  COMMON STOCK SUBJECT TO PLAN; OTHER LIMITATIONS.

    The  total  number of  shares  of Common  Stock  reserved and  available for
issuance under the  Plan shall  be 12,000,000; PROVIDED,  that not  more than  3
million  of such shares shall be issued  as Restricted Stock. No participant may
be granted  Awards  covering  in  excess  of  100,000  shares  of  Common  Stock

                                      K-3
<PAGE>
in  any one  calendar year.  Shares subject to  an Award  under the  Plan may be
authorized and unissued shares or may be treasury shares. No participant may  be
granted  Performance Units in any one calendar year payable in cash in an amount
that would exceed $1,000,000.

    Subject to Section 7(c)(iv), if any shares of Restricted Stock are forfeited
for which the  participant did not  receive any benefits  of ownership (as  such
phrase is construed by the Commission or its staff), or if any Stock Option (and
related Stock Appreciation Right, if any) terminates without being exercised, or
if  any Stock Appreciation Right  is exercised for cash,  shares subject to such
Awards shall again be available for distribution in connection with Awards under
the Plan.

    In the event  of any  change in corporate  capitalization, such  as a  stock
split,   or  a  corporate  transaction,   such  as  any  merger,  consolidation,
separation, including a spin-off, or other distribution of stock or property  of
the Company, any reorganization (whether or not such reorganization comes within
the  definition of  such term  in Section  368 of  the Code)  or any  partial or
complete liquidation  of the  Company,  the Committee  or  Board may  make  such
substitution  or adjustments in the aggregate number and kind of shares reserved
for issuance under  the Plan, in  the number,  kind and option  price of  shares
subject  to  outstanding Stock  Options and  Stock  Appreciation Rights,  in the
number and kind of shares subject to other outstanding Awards granted under  the
Plan and/or such other equitable substitution or adjustments as it may determine
to  be appropriate in its sole discretion; PROVIDED, HOWEVER, that the number of
shares subject to any Award shall always be a whole number. Such adjusted option
price shall also be used to determine the amount payable by the Company upon the
exercise of any Stock Appreciation Right associated with any Stock Option.

    Section 4.  ELIGIBILITY.

    Officers and employees of the Company and its Affiliates who are responsible
for or contribute to the management, growth and profitability of the business of
the Company and its Affiliates are eligible to be granted Awards under the Plan.
No grant shall be made under this Plan to a director who is not an officer or  a
salaried employee.

    Section 5.  STOCK OPTIONS.

    Stock  Options may be granted  alone or in addition  to other Awards granted
under the Plan and may be of two types: Incentive Stock Options and Nonqualified
Stock Options. Any Stock Option granted under the Plan shall be in such form  as
the Committee may from time to time approve.

    The Committee shall have the authority to grant any optionee Incentive Stock
Options, Nonqualified Stock Options or both types of Stock Options (in each case
with  or  without Stock  Appreciation  Rights); PROVIDED,  HOWEVER,  that grants
hereunder  are  subject  to  the   aggregate  limit  on  grants  to   individual
participants set forth in Section 3. Incentive Stock Options may be granted only
to  employees of the Company and its subsidiaries (within the meaning of Section
424(f) of the Code). To the extent that any Stock Option is not designated as an
Incentive Stock Option or even if so designated does not qualify as an Incentive
Stock Option, it shall constitute a Nonqualified Stock Option.

    Stock Options  shall  be  evidenced  by option  agreements,  the  terms  and
provisions  of which may differ. An option  agreement shall indicate on its face
whether it is intended  to be an  agreement for an Incentive  Stock Option or  a
Nonqualified  Stock Option. The grant of a  Stock Option shall occur on the date
the Committee by  resolution selects an  individual to be  a participant in  any
grant  of a Stock Option, determines the number  of shares of Common Stock to be
subject to such Stock Option to be granted to such individual and specifies  the
terms and provisions of the Stock Option. The Company shall notify a participant
of  any grant of  a Stock Option,  and a written  option agreement or agreements
shall be duly  executed and delivered  by the Company  to the participant.  Such
agreement or agreements shall become effective upon execution by the Company and
the participant.

    Anything  in the Plan to  the contrary notwithstanding, no  term of the Plan
relating to Incentive Stock Options shall be interpreted, amended or altered nor
shall any discretion or authority granted under  the Plan be exercised so as  to
disqualify the Plan under Section 422 of the Code or, without the consent of the
optionee  affected, to disqualify any Incentive  Stock Option under such Section
422.

                                      K-4
<PAGE>
    Stock Options granted under the Plan shall be subject to the following terms
and conditions and  shall contain such  additional terms and  conditions as  the
Committee shall deem desirable:

        (a)    OPTION  PRICE.    The option  price  per  share  of  Common Stock
    purchasable under a Stock  Option shall be determined  by the Committee  and
    set  forth in  the option  agreement, and  shall not  be less  than the Fair
    Market Value of the Common Stock subject to the Stock Option on the date  of
    grant.

        (b)   OPTION TERM.  The term of  each Stock Option shall be fixed by the
    Committee, but no Incentive Stock Option  shall be exercisable more than  10
    years after the date the Stock Option is granted.

        (c)  EXERCISABILITY.  Except as otherwise provided herein, Stock Options
    shall  be exercisable at  such time or  times and subject  to such terms and
    conditions as  shall  be  determined  by the  Committee.  If  the  Committee
    provides  that any  Stock Option  is exercisable  only in  installments, the
    Committee may at  any time  waive such installment  exercise provisions,  in
    whole  or in part, based on such  factors as the Committee may determine. In
    addition, the Committee may at any time accelerate the exercisability of any
    Stock Option.

        (d)  METHOD OF EXERCISE.  Subject  to the provisions of this Section  5,
    Stock  Options may be exercised, in whole or in part, at any time during the
    option term by giving written notice  of exercise to the Company  specifying
    the  number of  shares of  Common Stock  subject to  the Stock  Option to be
    purchased.

    Such notice shall be accompanied by payment in full of the purchase price by
certified or bank check or such other  instrument as the Company may accept.  If
approved  by the Committee, payment in  full or in part may  also be made in the
form of unrestricted  Common Stock  already owned by  the optionee  of the  same
class  as the Common Stock subject  to the Stock Option and,  in the case of the
exercise of a Nonqualified  Stock Option, Restricted Stock  subject to an  Award
hereunder  which is of the  same class as the Common  Stock subject to the Stock
Option (based, in each case, on the Fair Market Value of the Common Stock on the
date the Stock Option is exercised); PROVIDED, HOWEVER, that, in the case of  an
Incentive Stock Option, the right to make a payment in the form of already owned
shares  of Common  Stock of the  same class as  the Common Stock  subject to the
Stock Option may be authorized only at the time the Stock Option is granted.

    If payment of the  option exercise price of  a Nonqualified Stock Option  is
made  in whole or in part in the  form of Restricted Stock, the number of shares
of Common Stock to be received upon such exercise equal to the number of  shares
of  Restricted Stock  used for  payment of  the option  exercise price  shall be
subject to the same forfeiture restrictions  to which such Restricted Stock  was
subject, unless otherwise determined by the Committee.

    In  the discretion  of the  Committee, payment for  any shares  subject to a
Stock Option may also be made by delivering a properly executed exercise  notice
to  the Company, together with a copy of irrevocable instructions to a broker to
deliver promptly to the Company the amount  of sale or loan proceeds to pay  the
purchase  price, and, if  requested by the  Company, the amount  of any federal,
state, local  or foreign  withholding taxes.  To facilitate  the foregoing,  the
Company  may enter into  agreements for coordinated procedures  with one or more
brokerage firms.

    No shares of Common  Stock shall be issued  until full payment therefor  has
been  made. Subject  to any  forfeiture restrictions that  may apply  if a Stock
Option is exercised using  Restricted Stock, an optionee  shall have all of  the
rights  of a shareholder  of the Company  holding the class  or series of Common
Stock that is subject to such Stock Option (including, if applicable, the  right
to  vote the shares and  the right to receive  dividends), when the optionee has
given written notice  of exercise,  has paid  in full  for such  shares and,  if
requested, has given the representation described in Section 13(a).

        (e)   NONTRANSFERABILITY  OF STOCK  OPTIONS.   No Stock  Option shall be
    transferable by  the optionee  other than  (i) by  will or  by the  laws  of
    descent and distribution or (ii) in the case of a

                                      K-5
<PAGE>
    Nonqualified  Stock Option, pursuant to a  gift to such optionee's children,
    whether directly or  indirectly or  by means of  a trust  or partnership  or
    otherwise, if expressly permitted under the applicable option agreement. All
    Stock  Options shall be exercisable, during the optionee's lifetime, only by
    the optionee or by the guardian or legal representative of the optionee,  it
    being understood that the terms "holder" and "optionee" include the guardian
    and  legal representative of the optionee  named in the option agreement and
    any person to whom an option is  transferred by will or the laws of  descent
    and  distribution or,  in the  case of a  Nonqualified Stock  Option, a gift
    permitted under the applicable option agreement.

        (f)    TERMINATION  BY  DEATH.    Unless  otherwise  determined  by  the
    Committee,  if an optionee's  employment terminates by  reason of death, any
    Stock Option  held by  such optionee  may thereafter  be exercised,  to  the
    extent  then exercisable, or on such  accelerated basis as the Committee may
    determine, for a period of one year  (or such other period as the  Committee
    may  specify in the option  agreement) from the date  of such death or until
    the expiration of the stated term of such Stock Option, whichever period  is
    the shorter.

        (g)   TERMINATION BY REASON OF  DISABILITY.  Unless otherwise determined
    by the  Committee,  if an  optionee's  employment terminates  by  reason  of
    Disability,  any  Stock  Option  held by  such  optionee  may  thereafter be
    exercised by the optionee, to the extent  it was exercisable at the time  of
    termination,  or on such  accelerated basis as  the Committee may determine,
    for a period of  three years (or  such shorter period  as the Committee  may
    specify  in  the option  agreement)  from the  date  of such  termination of
    employment or until the expiration of the stated term of such Stock  Option,
    whichever  period is  the shorter; PROVIDED,  HOWEVER, that  if the optionee
    dies within such three-year period (or such shorter period), any unexercised
    Stock Option held by such optionee shall, notwithstanding the expiration  of
    such  three-year (or such shorter) period, continue to be exercisable to the
    extent to which it was exercisable at the  time of death for a period of  12
    months  from the date  of such death  or until the  expiration of the stated
    term of such Stock Option, whichever period is the shorter. In the event  of
    termination  of employment  by reason of  Disability, if  an Incentive Stock
    Option is exercised after the expiration of the exercise periods that  apply
    for  purposes of Section 422 of the  Code, such Stock Option will thereafter
    be treated as a Nonqualified Stock Option.

        (h)  TERMINATION BY REASON  OF RETIREMENT.  Unless otherwise  determined
    by  the  Committee,  if an  optionee's  employment terminates  by  reason of
    Retirement, any  Stock  Option  held  by such  optionee  may  thereafter  be
    exercised  by the optionee, to the extent  it was exercisable at the time of
    such  Retirement,  or  on  such  accelerated  basis  as  the  Committee  may
    determine,  for  a period  of three  years  (or such  shorter period  as the
    Committee may  specify  in the  option  agreement)  from the  date  of  such
    termination of employment or until the expiration of the stated term of such
    Stock  Option, whichever period  is the shorter;  PROVIDED, HOWEVER, that if
    the optionee  dies  within such  three-year  (or such  shorter)  period  any
    unexercised  Stock Option held  by such optionee  shall, notwithstanding the
    expiration of  such three-year  (or  such shorter)  period, continue  to  be
    exercisable  to the extent to which it  was exercisable at the time of death
    for a  period  of 12  months  from  the date  of  such death  or  until  the
    expiration  of the stated term of such Stock Option, whichever period is the
    shorter. In the event of termination of employment by reason of  Retirement,
    if  an  Incentive Stock  Option  is exercised  after  the expiration  of the
    exercise periods that apply  for purposes of Section  422 of the Code,  such
    Stock Option will thereafter be treated as a Nonqualified Stock Option.

        (i)   OTHER TERMINATION.  Unless  otherwise determined by the Committee,
    if an optionee incurs a Termination of Employment for any reason other  than
    death,  Disability or  Retirement, any  Stock Option  held by  such optionee
    shall thereupon terminate, except that such Stock Option, to the extent then
    exercisable, or on such  accelerated basis as  the Committee may  determine,
    may  be  exercised for  the lesser  of three  months from  the date  of such
    Termination of Employment or the balance of such Stock Option's stated  term
    if  such Termination of Employment of the optionee is involuntary; PROVIDED,
    HOWEVER,   that    if    the    optionee    dies    within    such    three-

                                      K-6
<PAGE>
    month  period, any  unexercised Stock  Option held  by such  optionee shall,
    notwithstanding the expiration  of such three-month  period, continue to  be
    exercisable  to the extent to which it  was exercisable at the time of death
    for a  period  of 12  months  from  the date  of  such death  or  until  the
    expiration  of the stated term of such Stock Option, whichever period is the
    shorter. Notwithstanding the foregoing, if an optionee incurs a  Termination
    of  Employment at or after a Change in Control (as defined in Section 9(b)),
    other than by reason  of death, Disability or  Retirement, any Stock  Option
    held  by such optionee shall be exercisable for the lesser of (1) six months
    and one day from  the date of  such Termination of  Employment, and (2)  the
    balance  of such Stock Option's stated term.  In the event of Termination of
    Employment, if an Incentive Stock  Option is exercised after the  expiration
    of  the exercise periods that apply for purposes of Section 422 of the Code,
    such Stock Option will thereafter be treated as a Nonqualified Stock Option.

        (j)  CASHING  OUT OF  STOCK OPTION.   On  receipt of  written notice  of
    exercise,  the Committee may elect to cash out all or part of the portion of
    the shares of Common Stock  for which a Stock  Option is being exercised  by
    paying  the optionee an amount, in cash or Common Stock, equal to the excess
    of the Fair Market Value of the Common Stock over the option price times the
    number of shares of Common Stock for which the Option is being exercised  on
    the effective date of such cash-out.

        Cash-outs  pursuant to  this Section  5(j) relating  to Options  held by
    optionees who are actually  or potentially subject to  Section 16(b) of  the
    Exchange Act shall comply with the "window period" provisions of Rule 16b-3,
    to  the extent  applicable, and, in  the case of  cash-outs of Non-Qualified
    Stock Options  held by  such  optionees, the  Committee may  determine  Fair
    Market Value under the pricing rule set forth in Section 6(b)(ii)(2).

        (k)  CHANGE IN CONTROL CASH-OUT.  Notwithstanding any other provision of
    the  Plan, during the 60-day period from  and after a Change in Control (the
    "Exercise Period"), unless  the Committee shall  determine otherwise at  the
    time  of grant, an optionee  shall have the right,  whether or not the Stock
    Option is fully exercisable and in lieu of the payment of the exercise price
    for the shares of Common Stock being purchased under the Stock Option and by
    giving notice  to the  Company, to  elect (within  the Exercise  Period)  to
    surrender  all or  part of the  Stock Option  to the Company  and to receive
    cash, within 30 days  of such notice,  in an amount equal  to the amount  by
    which  the Change in Control Price per share  of Common Stock on the date of
    such election shall  exceed the  exercise price  per share  of Common  Stock
    under  the Stock Option (the "Spread") multiplied by the number of shares of
    Common Stock granted under  the Stock Option as  to which the right  granted
    under  this Section 5(k) shall have  been exercised; PROVIDED, HOWEVER, that
    if the Change  in Control is  within six months  of the date  of grant of  a
    particular Stock Option held by an optionee who is an officer or director of
    the  Company and  is subject to  Section 16(b)  of the Exchange  Act no such
    election shall be made  by such optionee with  respect to such Stock  Option
    prior  to six  months from the  date of grant.  However, if the  end of such
    60-day period from and after a Change in Control is within six months of the
    date of grant of  a Stock Option held  by an optionee who  is an officer  or
    director of the Company and is subject to Section 16(b) of the Exchange Act,
    such  Stock Option shall be cancelled in  exchange for a cash payment to the
    optionee, effected on the day which is six months and one day after the date
    of grant of such  Option, equal to  the Spread multiplied  by the number  of
    shares of Common Stock granted under the Stock Option.

    Section 6.  STOCK APPRECIATION RIGHTS.

    (a)    GRANT AND  EXERCISE.   Stock  Appreciation Rights  may be  granted in
conjunction with all or part of any Stock Option granted under the Plan. In  the
case  of a Nonqualified  Stock Option, such  rights may be  granted either at or
after the time of grant of such Stock Option. In the case of an Incentive  Stock
Option,  such rights  may be  granted only at  the time  of grant  of such Stock
Option. A Stock Appreciation Right shall terminate and no longer be  exercisable
upon the termination or exercise of the related Stock Option.

                                      K-7
<PAGE>
    A  Stock Appreciation  Right may be  exercised by an  optionee in accordance
with Section 6(b) by  surrendering the applicable portion  of the related  Stock
Option  in accordance  with procedures established  by the  Committee. Upon such
exercise and surrender,  the optionee  shall be  entitled to  receive an  amount
determined  in the manner  prescribed in Section 6(b).  Stock Options which have
been so surrendered  shall no longer  be exercisable to  the extent the  related
Stock Appreciation Rights have been exercised.

    (b)   TERMS AND CONDITIONS.   Stock Appreciation Rights  shall be subject to
such terms and conditions as shall be determined by the Committee, including the
following:

        (i) Stock Appreciation Rights shall be exercisable only at such time  or
    times  and to  the extent that  the Stock  Options to which  they relate are
    exercisable in accordance with the provisions of Section 5 and this  Section
    6;  PROVIDED,  HOWEVER,  that  a  Stock  Appreciation  Right  shall  not  be
    exercisable during the first six  months of its term  by an optionee who  is
    actually or potentially subject to Section 16(b) of the Exchange Act, except
    that  this limitation shall not apply in the event of death or Disability of
    the optionee prior to the expiration of the six-month period.

        (ii) Upon the exercise of a Stock Appreciation Right, an optionee  shall
    be  entitled to receive  an amount in  cash, shares of  Common Stock or both
    equal in value to the excess of the Fair Market Value of one share of Common
    Stock over the option price per share specified in the related Stock  Option
    multiplied   by  the  number  of  shares  in  respect  of  which  the  Stock
    Appreciation Right shall have been exercised, with the Committee having  the
    right to determine the form of payment.

        In  the case of Stock Appreciation Rights relating to Stock Options held
    by optionees who are actually or potentially subject to Section 16(b) of the
    Exchange Act, the Committee:

           (1) may require that such Stock Appreciation Rights be exercised  for
       cash only in accordance with the applicable "window period" provisions of
       Rule 16b-3; and

           (2) in the case of Stock Appreciation Rights relating to Nonqualified
       Stock  Options,  may provide  that the  amount  to be  paid in  cash upon
       exercise of such Stock  Appreciation Rights during  a Rule 16b-3  "window
       period"  shall be  based on  the highest of  the daily  means between the
       highest and lowest reported sales prices  of the Common Stock on the  New
       York  Stock Exchange or  other national securities  exchange on which the
       shares are listed  or on NASDAQ,  as applicable, on  any day during  such
       "window period."

       (iii)  Stock Appreciation Rights shall  be transferable only to permitted
    transferees of the underlying Stock Option in accordance with Section 5(e).

       (iv) Upon the exercise of a Stock Appreciation Right, the Stock Option or
    part thereof to  which such  Stock Appreciation  Right is  related shall  be
    deemed to have been exercised for the purpose of the limitation set forth in
    Section  3 on the  number of shares of  Common Stock to  be issued under the
    Plan, but only to the extent of the  number of shares as to which the  Stock
    Appreciation Right is exercised at the time of exercise.

    Section 7.  RESTRICTED STOCK.

    (a)  ADMINISTRATION.  Shares of Restricted Stock may be awarded either alone
or  in addition  to other  Awards granted  under the  Plan. The  Committee shall
determine the officers  and employees to  whom and  the time or  times at  which
grants  of Restricted Stock will be awarded,  the number of shares to be awarded
to any  participant (subject  to the  aggregate limit  on grants  to  individual
participants  set forth in Section  3), the conditions for  vesting, the time or
times within which such Awards may be subject to forfeiture and any other  terms
and conditions of the Awards, in addition to those contained in Section 7(c).

    The Committee shall in the case of Covered Employees, and may in the case of
other   Participants,  condition  the  vesting  of  Restricted  Stock  upon  the
attainment of Performance Goals established

                                      K-8
<PAGE>
before or at  the time of  grant. The  Committee may, in  addition to  requiring
satisfaction  of any applicable  Performance Goals, also  condition vesting upon
the continued service  of the  participant. The provisions  of Restricted  Stock
Awards  (including the applicable  Performance Goals) need not  be the same with
respect to each recipient.

    (b)  AWARDS AND CERTIFICATES.  Shares of Restricted Stock shall be evidenced
in such  manner as  the  Committee may  deem appropriate,  including  book-entry
registration  or issuance  of one  or more  stock certificates.  Any certificate
issued in respect of shares of Restricted Stock shall be registered in the  name
of such participant and shall bear an appropriate legend referring to the terms,
conditions,  and  restrictions applicable  to such  Award, substantially  in the
following form:

        "The transferability  of  this  certificate  and  the  shares  of  stock
    represented  hereby  are  subject  to the  terms  and  conditions (including
    forfeiture) of  the Primergy  Stock Incentive  Plan and  a Restricted  Stock
    Agreement.  Copies of such Plan and Agreement  are on file at the offices of
    Primergy Corporation at                                     ."

The Committee may require that the  certificates evidencing such shares be  held
in  custody by the Company until the  restrictions thereon shall have lapsed and
that, as a  condition of any  Award of Restricted  Stock, the participant  shall
have  delivered a stock power,  endorsed in blank, relating  to the Common Stock
covered by such Award.

    (c)  TERMS AND CONDITIONS.  Shares  of Restricted Stock shall be subject  to
the following terms and conditions:

        (i)  Subject to the provisions of  the Plan (including Section 5(d)) and
    the Restricted Stock Agreement referred  to in Section 7(c)(vi), during  the
    period, if any, set by the Committee, commencing with the date of such Award
    for which such participant's continued service is required (the "Restriction
    Period"),  and  until the  later of  (i) the  expiration of  the Restriction
    Period and  (ii) the  date the  applicable Performance  Goals (if  any)  are
    satisfied, the participant shall not be permitted to sell, assign, transfer,
    pledge  or  otherwise  encumber  shares of  Restricted  Stock.  Within these
    limits, the Committee may provide for  the lapse of restrictions based  upon
    period  of service in installments or otherwise and may accelerate or waive,
    in whole  or in  part, restrictions  based upon  period of  service or  upon
    performance;  PROVIDED, HOWEVER, that  in the case  of Restricted Stock with
    respect to  which  a  participant  is a  Covered  Employee,  any  applicable
    Performance Goals have been satisfied.

        (ii)  Except as provided in this  paragraph (ii) and Section 7(c)(i) and
    the Restricted Stock Agreement, the participant shall have, with respect  to
    the  shares of Restricted Stock,  all of the rights  of a shareholder of the
    Company holding the class or series of  Common Stock that is the subject  of
    the Restricted Stock, including, if applicable, the right to vote the shares
    and  the  right to  receive  any cash  dividends.  If so  determined  by the
    Committee in  the  applicable  Restricted Stock  Agreement  and  subject  to
    Section  13(f) of  the Plan, (1)  cash dividends  on the class  or series of
    Common Stock that  is the  subject of the  Restricted Stock  Award shall  be
    automatically  deferred and reinvested in  additional Restricted Stock, held
    subject to the vesting of the  underlying Restricted Stock, or held  subject
    to meeting Performance Goals applicable only to dividends, and (2) dividends
    payable in Common Stock shall be paid in the form of Restricted Stock of the
    same  class as  the Common  Stock with  which such  dividend was  paid, held
    subject to the vesting of the  underlying Restricted Stock, or held  subject
    to meeting Performance Goals applicable only to dividends.

       (iii)   Except  to  the  extent  otherwise  provided  in  the  applicable
    Restricted Stock Agreement, any applicable employment agreement and Sections
    7(c)(i),  7(c)(iv)  and  9(a)(ii),  upon  a  participant's  Termination   of
    Employment  for  any  reason during  the  Restriction Period  or  before the
    applicable Performance  Goals are  satisfied, all  shares still  subject  to
    restriction shall be forfeited by the participant.

                                      K-9
<PAGE>
       (iv)  Except to the extent otherwise provided in Section 9(a)(ii), in the
    event that  a  participant  retires  or  such  participant's  employment  is
    involuntarily  terminated, the Committee shall  have the discretion to waive
    in whole or in part  any or all remaining  restrictions (other than, in  the
    case  of Restricted Stock with  respect to which a  participant is a Covered
    Employee, satisfaction  of  the  applicable  Performance  Goals  unless  the
    participant's  employment is  terminated by  reason of  death or Disability)
    with respect to any or all of such participant's shares of Restricted Stock.

        (v) If and when the applicable  Performance Goals are satisfied and  the
    Restriction  Period  expires without  a prior  forfeiture of  the Restricted
    Stock, unlegended certificates  for such  shares shall be  delivered to  the
    participant upon surrender of the legended certificates.

       (vi)  Each Award shall be confirmed by, and be subject to the terms of, a
    Restricted Stock Agreement.

    Section 8.  PERFORMANCE UNITS.

    (a)  ADMINISTRATION.   Performance Units may be  awarded either alone or  in
addition  to  other Awards  granted  under the  Plan.  Performance Units  may be
denominated in shares of  Common Stock or  cash, or may  represent the right  to
receive  dividend equivalents  with respect  to shares  of Common  Stock, as the
Committee shall  determine.  The  Committee shall  determine  the  officers  and
employees  to whom  and the time  or times  at which Performance  Units shall be
awarded, the  form  and  number  of  Performance Units  to  be  awarded  to  any
participant (subject to the aggregate limit on grants to individual participants
set forth in Section 3), the duration of the Award Cycle and any other terms and
conditions of the Award, in addition to those contained in Section 8(b).

    The  Committee shall condition the settlement  of Performance Units upon the
attainment of Performance Goals.  The provisions of  such Awards (including  the
applicable  Performance  Goals)  need  not  be the  same  with  respect  to each
recipient.

    (b)  TERMS AND CONDITIONS.  Performance Units Awards shall be subject to the
following terms and conditions:

        (i) Subject  to the  provisions of  the Plan  and the  Performance  Unit
    Agreement  referred to  in Section  8(b)(vi), Performance  Units may  not be
    sold, assigned,  transferred, pledged  or  otherwise encumbered  during  the
    Award  Cycle.  At the  expiration of  the Award  Cycle, the  Committee shall
    evaluate actual performance in light of the Performance Goals for such Award
    and  shall  determine  the  number  of  Performance  Units  granted  to  the
    participant  which  have been  earned and  the Committee  may then  elect to
    deliver  cash,  shares  of  Common  Stock,  or  a  combination  thereof,  in
    settlement  of the  earned Performance Units,  in accordance  with the terms
    thereof.

        (ii)  Except  to  the  extent  otherwise  provided  in  the   applicable
    Performance  Unit  Agreement and  Sections 8(b)(iii)  and 9(a)(iii),  upon a
    participant's Termination  of Employment  for any  reason during  the  Award
    Cycle  or before the applicable Performance  Goals are satisfied, the rights
    to the  shares  still  covered  by the  Performance  Units  Award  shall  be
    forfeited by the participant.

       (iii)  Except to the  extent otherwise provided  in Section 9(a)(iii), in
    the event that a participant's  employment is involuntarily terminated,  the
    Committee  shall have the discretion to waive in whole or in part any or all
    remaining payment limitations (other than, in the case of Performance  Units
    with  respect to which a participant  is a Covered Employee, satisfaction of
    the applicable  Performance Goals  unless  the participant's  employment  is
    terminated  by reason of death or Disability)  with respect to any or all of
    such participant's Performance Units.

       (iv) A participant may elect to further defer receipt of the  Performance
    Units payable under an Award (or an installment of an Award) for a specified
    period  or until a specified event, subject  in each case to the Committee's
    approval and to such terms as are determined by the Committee (the "Elective
    Deferral Period"). Subject to any exceptions adopted by the Committee,  such
    election must generally be made prior to commencement of the Award Cycle for
    the Award (or for such installment of an Award).

        (v)  If and when the applicable  Performance Goals are satisfied and the
    Elective  Deferral  Period  expires  without  a  prior  forfeiture  of   the
    Performance  Units, payment in accordance  with Section 8(b)(i) hereof shall
    be made to the participant.

       (vi) Each Award shall be confirmed by, and be subject to the terms of,  a
    Performance Unit Agreement.

    Section 9.  CHANGE IN CONTROL PROVISIONS.

    (a)   IMPACT OF EVENT.   Notwithstanding any other  provision of the Plan to
the contrary, in the event of a Change in Control:

    exercisable and vested shall become fully exercisable and vested to the full
    extent of the original grant.

        (ii) The restrictions  applicable to any  Restricted Stock shall  lapse,
    and  such Restricted Stock shall become  free of all restrictions and become

    beneficial ownership (within the meaning of Rule 13d-3 promulgated under the
    Exchange Act) of 20% or  more of either (1)  the then outstanding shares  of
    common  stock of the Company (the "Outstanding Company Common Stock") or (2)
    the combined voting power of the  then outstanding voting securities of  the
    Company  entitled  to  vote  generally in  the  election  of  directors (the
    "Outstanding Company Voting Securities"); excluding, however, the following:
    (1) any acquisition directly from the Company, other than an acquisition  by
    virtue  of the exercise of a  conversion privilege unless the security being
    so converted  was  itself  acquired  directly  from  the  Company,  (2)  any
    acquisition by the Company, (3) any acquisition by any employee benefit plan
    (or related trust) sponsored or maintained by the Company or any corporation
    controlled by the Company or (4) any acquisition by any corporation pursuant
    to  a transaction which complies with clauses (1), (2) and (3) of subsection

        (ii) A change in the composition of the Board such that the  individuals
    who,  as of the Effective Time, constitute the Board, after giving effect to
    the reconstitution  of the  Board in  accordance with  the Merger  Agreement
    (such Board shall be hereinafter referred to as the "Incumbent Board") cease
    for  any reason to  constitute at least  a majority of  the Board; PROVIDED,
    HOWEVER, for purposes of this Section 9(b), that any individual who  becomes
    a  member of the Board subsequent to  the Effective Time, whose election, or
    nomination for election  by the  Company's shareholders, was  approved by  a
    vote  of at  least a majority  of those  individuals who are  members of the
    Board and who were also members of the Incumbent Board (or deemed to be such
    pursuant to this proviso) shall be considered as though such individual were
    a member  of the  Incumbent  Board; but,  PROVIDED  FURTHER, that  any  such
    individual  whose initial assumption of office  occurs as a result of either
    an actual or  threatened election contest  (as such terms  are used in  Rule
    14a-11 of Regulation 14A promulgated under the Exchange Act) or other actual
    or  threatened solicitation  of proxies  or consents  by or  on behalf  of a
    Person other than the Board  shall not be so considered  as a member of  the
    Incumbent Board; or

                                      K-11
<PAGE>
       (iii)   The  approval   by  the   shareholders  of   the  Company   of  a
    reorganization, merger,  consolidation,  share  exchange or  sale  or  other
    disposition  of  all  or substantially  all  of  the assets  of  the Company
    ("Corporate Transaction") or, if consummation of such Corporate  Transaction
    is  subject, at the time of such approval by shareholders, to the consent of
    any government or governmental agency, the obtaining of such consent (either
    explicitly or  implicitly  by  consummation);  excluding,  however,  such  a
    Corporate  Transaction pursuant to which (1) all or substantially all of the
    individuals and entities who are the beneficial owners, respectively, of the
    Outstanding Company Common Stock  and Outstanding Company Voting  Securities
    immediately  prior  to  such Corporate  Transaction  will  beneficially own,
    directly or  indirectly, more  than 60%  of, respectively,  the  outstanding
    shares  of  common  stock,  and  the  combined  voting  power  of  the  then
    outstanding voting securities entitled to vote generally in the election  of
    directors,  as  the case  may  be, of  the  corporation resulting  from such
    Corporate Transaction (including, without limitation, a corporation which as
    a result of such transaction owns the Company or all or substantially all of
    the Company's assets either directly or through one or more subsidiaries) in
    substantially the same proportions as their ownership, immediately prior  to
    such  Corporate  Transaction, of  the Outstanding  Company Common  Stock and
    Outstanding Company Voting  Securities, as the  case may be,  (2) no  Person
    (other than the Company, any employee benefit plan (or related trust) of the
    Company  or such corporation resulting from such Corporate Transaction) will
    beneficially own, directly or indirectly, 20% or more of, respectively,  the
    outstanding  shares of common  stock of the  corporation resulting from such
    Corporate Transaction or the combined voting power of the outstanding voting
    securities of such corporation entitled to vote generally in the election of
    directors except to  the extent  that such  ownership existed  prior to  the
    Corporate  Transaction and (3) individuals who were members of the Incumbent
    Board will constitute at  least a majority  of the members  of the board  of
    directors of the corporation resulting from such Corporate Transaction; or

       (iv)  The  approval by  the  shareholders of  the  Company of  a complete
    liquidation or dissolution of the Company.

    (c)  CHANGE IN CONTROL PRICE.  For purposes of the Plan, "Change in  Control
Price" means the higher of (i) the highest reported sales price, regular way, of
a  share  of Common  Stock in  any transaction  reported on  the New  York Stock
Exchange Composite Tape  or other  national exchange  on which  such shares  are
listed  or on NASDAQ during the 60-day period prior to and including the date of
a Change in Control or (ii) if the  Change in Control is the result of a  tender
or  exchange offer or  a Corporate Transaction,  the highest price  per share of
Common Stock paid  in such tender  or exchange offer  or Corporate  Transaction;
PROVIDED,  HOWEVER, that (x) in the case of  a Stock Option which (A) is held by
an optionee who  is an  officer or  director of the  Company and  is subject  to
Section  16(b) of the  Exchange Act and (B)  was granted within  240 days of the
Change in Control, then the Change in Control Price for such Stock Option  shall
be  the Fair Market Value of  the Common Stock on the  date such Stock Option is
exercised or deemed exercised and (y) in the case of Incentive Stock Options and
Stock Appreciation Rights  relating to  Incentive Stock Options,  the Change  in
Control Price shall be in all cases the Fair Market Value of the Common Stock on
the  date such Incentive Stock Option  or Stock Appreciation Right is exercised.
To the extent  that the  consideration paid  in any  such transaction  described
above consists all or in part of securities or other non-cash consideration, the
value  of such securities or other non-cash consideration shall be determined in
the sole discretion of the Board.

    Section 10.  LOANS.

    The Company  may make  loans  to a  participant  in connection  with  Awards
subject  to  the  following  terms  and  conditions  and  such  other  terms and
conditions not inconsistent  with the Plan  as the Committee  shall impose  from
time  to time, including  without limitation the  rate of interest,  if any, and
whether such loan shall be recourse or non-recourse.

                                      K-12
<PAGE>
    No loan made under the Plan shall exceed the sum of (i) the aggregate  price
payable  with respect to the  Award in relation to which  the loan is made, plus
(ii) the amount  of the  reasonably estimated  combined amounts  of Federal  and
state income taxes payable by the participant.

    No  loan shall have an initial term  exceeding ten (10) years; PROVIDED that
the loans under the Plan shall be renewable at the discretion of the  Committee;
and  PROVIDED, FURTHER, that  the indebtedness under each  loan shall become due
and payable, as the  case may be,  on a date  no later than  (i) one year  after
Termination  of Employment due  to death, Retirement or  Disability, or (ii) the
day of Termination of Employment for any reason other than death, Retirement  or
Disability.

    Loans  under the Plan may be satisfied  by the participant, as determined by
the Committee, in cash  or, with the  consent of the Committee,  in whole or  in
part  in the form of unrestricted Common  Stock already owned by the participant
where such Common Stock shall be valued at Fair Market Value on the date of such
payment.

    When a loan shall have been made,  Common Stock with a Fair Market Value  on
the  date of such loan equivalent to the  amount of the loan shall be pledged by
the participant to the Company as security for payment of the unpaid balance  of
the  loan.  Any portions  of such  Common Stock  may, in  the discretion  of the
Committee, be  released from  time to  time  as it  deems not  to be  needed  as
security.

    The making of any loan is subject to satisfying all applicable laws, as well
as  any  regulations  and rules  of  the  Federal Reserve  Board  and  any other
governmental agency having jurisdiction.

    Section 11.  TERM, AMENDMENT AND TERMINATION.

    The Plan will terminate 10 years after the effective date of the Plan. Under
the Plan, Awards outstanding as of such  date shall not be affected or  impaired
by the termination of the Plan.

    The  Board  may amend,  alter, or  discontinue the  Plan, but  no amendment,
alteration or discontinuation shall be made which would (i) impair the rights of
an optionee under a Stock Option or  a recipient of a Stock Appreciation  Right,
Restricted Stock Award or Performance Unit Award theretofore granted without the
optionee's  or recipient's consent,  except such an amendment  made to cause the
Plan to qualify for the exemption provided by Rule 16b-3, or (ii) disqualify the
Plan from the exemption provided by  Rule 16b-3. In addition, no such  amendment
shall  be made without the approval of  the Company's shareholders to the extent
such approval is required by law or agreement.

    The Committee  may  amend the  terms  of any  Stock  Option or  other  Award
theretofore granted, prospectively or retroactively, but no such amendment shall
impair  the rights  of any  holder without the  holder's consent  except such an
amendment made to cause the Plan or Award to qualify for the exemption  provided
by Rule 16b-3.

    Subject to the above provisions, the Board shall have authority to amend the
Plan  to take into account changes in law  and tax and accounting rules, as well
as other developments and to grant Awards which qualify for beneficial treatment
under such rules without shareholder approval.

    Section 12.  UNFUNDED STATUS OF PLAN.

    It is presently  intended that the  Plan constitute an  "unfunded" plan  for
incentive and deferred compensation. The Committee may authorize the creation of
trusts  or other arrangements to meet the  obligations created under the Plan to
deliver Common  Stock or  make  payments; PROVIDED,  HOWEVER, that,  unless  the
Committee   otherwise  determines,  the  existence   of  such  trusts  or  other
arrangements is consistent with the "unfunded" status of the Plan.

    Section 13.  GENERAL PROVISIONS.

    (a) The Committee  may require  each person purchasing  or receiving  shares
pursuant  to an Award to represent to and agree with the Company in writing that
such person is acquiring the shares without a view to the distribution  thereof.
The  certificates for  such shares  may include  any legend  which the Committee
deems appropriate to reflect any restrictions on transfer.

                                      K-13
<PAGE>
    Notwithstanding any other provision of the Plan or agreements made  pursuant
thereto,  the Company shall not be required  to issue or deliver any certificate
or certificates for shares of Common  Stock under the Plan prior to  fulfillment
of all of the following conditions:

        (1) The listing or approval for listing upon notice of issuance, of such
    shares  on  the New  York  Stock Exchange,  Inc.,  or such  other securities
    exchange as may at the time be the principal market for the Common Stock;

        (2) Any  registration  or other  qualification  of such  shares  of  the
    Company  under any state or Federal law or regulation, or the maintaining in
    effect of any such registration  or other qualification which the  Committee
    shall, in its absolute discretion upon the advice of counsel, deem necessary
    or advisable; and

        (3)  The obtaining  of any other  consent, approval, or  permit from any
    state or  Federal governmental  agency  which the  Committee shall,  in  its
    absolute  discretion after receiving the advice  of counsel, determine to be
    necessary or advisable.

    (b) Nothing contained in the Plan shall prevent the Company or any Affiliate
from adopting other or additional compensation arrangements for its employees.

    (c) The adoption of the Plan shall not confer upon any employee any right to
continued employment nor shall  it interfere in  any way with  the right of  the
Company  or any  Affiliate to  terminate the employment  of any  employee at any
time.

    (d) No later than the date as of which an amount first becomes includible in
the gross income of the participant for Federal income tax purposes with respect
to any Award under the Plan, the  participant shall pay to the Company, or  make
arrangements  satisfactory to the Company regarding the payment of, any Federal,
state, local or foreign taxes  of any kind required by  law to be withheld  with
respect  to such amount. Unless otherwise determined by the Company, withholding
obligations may be  settled with Common  Stock, including Common  Stock that  is
part  of  the  Award  that  gives rise  to  the  with  holding  requirement. The
obligations of the Company under the  Plan shall be conditional on such  payment
or  arrangements,  and  the Company  and  its  Affiliates shall,  to  the extent
permitted by law,  have the  right to  deduct any  such taxes  from any  payment
otherwise due to the participant. The Committee may establish such procedures as
it  deems appropriate,  including the making  of irrevocable  elections, for the
settlement of withholding obligations with Common Stock.

    (e) At the time of grant, the  Committee may provide in connection with  any
grant  made under the Plan that the shares  of Common Stock received as a result
of such grant shall be subject to a right of first refusal pursuant to which the
participant shall  be required  to offer  to  the Company  any shares  that  the
participant  wishes to sell at  the then Fair Market  Value of the Common Stock,
subject to such other terms and conditions  as the Committee may specify at  the
time of grant.

    (f) The reinvestment of dividends in additional Restricted Stock at the time
of any dividend payment shall only be permissible if sufficient shares of Common
Stock  are available under Section 3  for such reinvestment (taking into account
then outstanding Stock Options and other Awards).

    (g) The Committee shall  establish such procedures  as it deems  appropriate
for  a participant to designate a beneficiary to whom any amounts payable in the
event of the participant's  death are to be  paid or by whom  any rights of  the
participant, after the participant's death, may be exercised.

    (h)  In the case of a grant of an Award to any employee of an Affiliate, the
Company may, if the Committee so directs, issue or transfer the shares of Common
Stock, if  any,  covered  by  the  Award  to  the  Affiliate,  for  such  lawful
consideration  as the Committee may specify, upon the condition or understanding
that the Affiliate will transfer the shares  of Common Stock to the employee  in
accordance  with the terms of  the Award specified by  the Committee pursuant to
the provisions of the Plan.

    (i) Notwithstanding any other  provision of the Plan,  if any right  granted
pursuant  to this Plan would make a Change in Control transaction ineligible for
pooling of interests accounting under

                                      K-14
<PAGE>
APB No. 16 that but for the nature of such grant would otherwise be eligible for
such accounting treatment, the  Committee shall have  the ability to  substitute
for the cash payable pursuant to such grant Common Stock (or the common stock of
the  issuer for  which the  Common Stock  is being  exchanged in  such Change in
Control transaction)  with a  Fair Market  Value equal  to the  cash that  would
otherwise be payable hereunder.

    (j)   The  Plan and all  Awards made  and actions taken  thereunder shall be
governed by and construed in accordance with the laws of the State of Wisconsin,
without reference to principles of conflict of laws.

    Section 14.  EFFECTIVE DATE OF PLAN.

    The Plan  shall be  effective  at the  Effective Time,  but  only if  it  is
previously  approved by the affirmative vote of a majority of the votes entitled
to be cast  by the holders  of the shares  of common stock  of Wisconsin  Energy
Corporation  represented at  a meeting and  entitled to  vote thereon (PROVIDED,
that the total vote cast represents over  50% of all the shares of common  stock
of Wisconsin Energy Corporation entitled to vote) and by the affirmative vote of
a  majority of the  votes entitled to  be cast by  the holders of  the shares of

                                 ADMINISTRATION

    The Plan shall be administered by the Committee. In administering the  Plan,
the Committee may at its option employ compensation consultants, accountants and
counsel  (who  may be  the  compensation consultants,  independent  auditors and
outside counsel of the Company or an  Affiliate) and other persons to assist  or
render advice to the Committee, all at the expense of the Company. The Committee
shall  have  sole  authority  to  make rules  and  regulations  relating  to the
administration of  the  Plan,  and  any interpretations  and  decisions  of  the
Committee with respect to the Plan shall be final and binding.

                                       IV
                                  ELIGIBILITY

    The  Committee shall, in  its sole discretion,  determine for each Incentive
Period those officers and salaried employees  of the Company and its  Affiliates
who  shall be eligible to participate in  the Plan (the "Participants") for such
Incentive Period based upon such Participants' opportunity to have a substantial
impact on  the  operating  results  of the  Company  or  an  Affiliate.  Nothing
contained  in the Plan shall  be construed as or be  evidence of any contract of
employment with any Participant for a term of any length nor shall participation
in the  Plan  in any  Incentive  Period  by any  Participant  require  continued
participation by such Participant in any subsequent Incentive Period.

                                       V
                       DETERMINATION OF INCENTIVE AWARDS

    Subject  to Article IX hereof, the amount  and terms of each Incentive Award
to a Participant shall be determined by and in the discretion of the  Committee.
The  Committee  may  condition  the  earning  of  an  Incentive  Award  upon the
attainment of  specified performance  goals, measured  over a  period ending  no
later  than the end  of the applicable Incentive  Period. Such performance goals
may relate to  the Participant  or the Company,  or any  Affiliate, division  or
department  of  the Company  for or  within which  the Participant  is primarily
employed, or  upon  such  other  factors or  criteria  as  the  Committee  shall
determine,  and may be different for  each Participant. Incentive Awards payable
under the Plan  will consist  of a  cash award from  the Company,  based upon  a
percentage  (which  may  exceed 100%)  of  the  Target Incentive  Award  and, if
applicable, the  degree  of achievement  of  such performance  goals.  Incentive
Awards  under this Plan for Covered Employees shall be subject to preestablished
Performance Goals in accordance with Article  IX hereof. Except with respect  to
Covered Employees, the

                                      L-3
<PAGE>
Committee  may, in its sole  discretion, increase or decrease  the amount of any
Incentive Award  payable to  a Participant  and, in  recognition of  changed  or
special  circumstances, may award  Incentive Awards to  Participants even though
the Incentive  Awards  are not  earned.  Incentive Awards  earned  or  otherwise
awarded  will  be paid  as soon  as  administratively feasible  on or  after the
Payment Date.

                                       VI
                           TERMINATION OF EMPLOYMENT

    In the  event that  a  Participant's employment  with  the Company  and  its
Affiliates terminates for any reason during the Incentive Period with respect to
any Incentive Awards, the balance of any Incentive Award which remains unpaid at
the  time of such termination shall be  payable to the Participant, or forfeited
by the Participant, in  accordance with the  terms of the  award granted by  the
Committee;  PROVIDED, HOWEVER, that in the case of a Covered Employee, no amount
shall be payable pursuant to the Plan unless the Performance Goals are satisfied
or the termination  of employment of  the Covered  Employee is due  to death  or
disability.  A Participant who remains employed through the Incentive Period but
is terminated  prior  to the  Payment  Date shall  be  entitled to  receive  any
Incentive  Award  payable to  such Participant  with  respect to  such Incentive
Period.

                                      VII
                          AMENDMENT AND DISCONTINUANCE

    The Board shall  have the right  to amend, alter,  discontinue or  otherwise
modify  the Plan from time  to time but no  such modification shall, without the
consent of  the  Participant  affected,  impair any  award  made  prior  to  the
effective date of the modification.

                                      VIII
                                 MISCELLANEOUS

    It  is presently  intended that the  Plan constitute an  "unfunded" plan for
incentive and deferred compensation. The Committee may authorize the creation of
trusts or other arrangements to meet  the payment obligations created under  the
Plan;  PROVIDED, HOWEVER, that,  unless the Committee  otherwise determines, the
existence of such trusts or other arrangements is consistent with the "unfunded"
status of the Plan. The  Plan shall be governed  by and construed in  accordance
with  the laws of  the State of  Wisconsin, without regard  to its principles of
conflict of laws.

                                       IX
                 PROCEDURES FOR CERTAIN DESIGNATED PARTICIPANTS

    Incentive Awards under the  Plan to Participants  who are Covered  Employees
shall  be  subject  to preestablished  Performance  Goals as  set  forth herein.
Notwithstanding Article V  hereof, the  Committee shall not  have discretion  to
modify the terms of awards to such Participants except as specifically set forth
in this Article IX.

    (a)   TARGET BONUS.  On or before the 90th day of each Incentive Period, and
in any  event before  25%  or more  of the  Incentive  Period has  elapsed,  the
Committee  shall  establish  in  writing  specific  Performance  Goals  for  the
Incentive Period, upon the attainment of  which will be conditioned the  payment
of Incentive Awards ("Special Incentive Awards") to such of the Participants who
may  be Covered  Employees. A  Special Incentive Award  shall consist  of a cash
award from the Company to be based upon a percentage (which may exceed 100%)  of
a Target Incentive Award. The extent, if any, to which a Special Incentive Award
will  be payable will be based upon  the degree of achievement of preestablished
Performance Goals over a specified Incentive Period; PROVIDED, HOWEVER, that the
Committee may, in its sole discretion,  reduce the amount which would  otherwise
be payable with respect to an Incentive Period.

                                      L-4
<PAGE>
    (b)   INCENTIVE  PERIOD.   The Incentive Period  will be  a period  of up to
twelve months, unless a shorter period is otherwise selected and established  in
writing  by the Committee at the time the Performance Goals are established with
respect to such Incentive Period.

    (c)  PERFORMANCE GOALS.  The Performance Goals established by the  Committee
at the time a Special Incentive Award is granted will be based on one or more of
the  following: earnings per share, market share, stock price, sales, costs, net
operating income, cash  flow, retained  earnings, return on  equity, results  of
customer  satisfaction surveys, aggregate product  price and other product price
measures, safety record, service reliability, demand-side management  (including
conservation  and load  management), operating and  maintenance cost management,
energy production availability, and  individual performance measures;  provided,
that  all Performance Goals shall be  objective performance goals satisfying the
requirements for "performance-based compensation" within the meaning of  Section
162(m)(4)  of  the  Code.  Such  Performance Goals  also  may  be  based  on the
attainment of  specified  levels  of  performance  of  the  Company  and/or  any
Affiliates  under one or  more of the  measures described above  relative to the
performance of other corporations.

    (d)  PAYMENT OF AN INCENTIVE AWARD.  At the time the Special Incentive Award
is granted, the Committee shall prescribe a formula to determine the  percentage
of  the Target  Incentive Award which  may be  payable based upon  the degree of
attainment of the Performance Goals during the Incentive Period. If the  minimum
Performance  Goals established by the Committee are  not met, no payment will be
made to a Participant who is a Covered Employee. To the extent that the  minimum
Performance  Goals are satisfied or surpassed, and upon written certification by
the Committee that  the Performance Goals  have been satisfied  to a  particular
extent  and any  other material  terms and  conditions of  the Special Incentive
Awards have  been  satisfied, payment  shall  be made  on  the Payment  Date  in
accordance  with the  prescribed formula based  upon a percentage  of the Target
Incentive Award  unless the  Committee determines,  in its  sole discretion,  to
reduce the payment to be made.

    (e)   MAXIMUM  PAYABLE.   The maximum amount  payable to  a Covered Employee
under this Plan for any fiscal year  of the Company pursuant to this Plan  shall
be $1,000,000.

                                       X
                               CHANGE IN CONTROL

    Notwithstanding  any  other provision  of this  Plan, (i)  upon a  Change in
Control, each  Participant  who is  employed  by  the Company  or  an  Affiliate
immediately  before the Change in Control shall be entitled to receive a payment
equal to  his  or her  Target  Incentive Award  for  the Incentive  Period  that
includes  the date of the  Change in Control, and  (ii) any additional Incentive
Award that becomes payable to such a Participant for that Incentive Period shall
be reduced  (but not  below zero)  by the  amount of  the payment  made to  such
Participant pursuant to clause (i) of this Article X.

                                       XI
                               DEFERRAL ELECTIONS

    The  Committee  may at  its option  establish  procedures pursuant  to which
Participants are  permitted to  defer the  receipt of  Incentive Awards  payable
hereunder.

                                      XII
                              SHAREHOLDER APPROVAL

    This  Plan shall  not become effective  with respect to  individuals who are
Covered Employees unless it shall have been approved by the affirmative vote  of
a  majority of the  votes entitled to  be cast by  the holders of  the shares of
common stock  of  Wisconsin Energy  Corporation  represented at  a  meeting  and
entitled  to vote thereon and by the affirmative vote of a majority of the total
voting power  of the  shares of  common stock  and preferred  stock of  Northern
States Power Company present in person or by proxy and entitled to vote thereon.

                      DISSENTERS' RIGHTS PROVISIONS OF THE
                       MINNESOTA BUSINESS CORPORATION ACT

    302A.471    RIGHTS OF  DISSENTING  SHAREHOLDERS.--   Subdivision  1. Actions
creating rights. A  shareholder of a  corporation may dissent  from, and  obtain
payment  for the fair value of the shareholder's  shares in the event of, any of
the following corporate actions:

        (a) An amendment of the  articles that materially and adversely  affects
    the  rights or  preferences of the  shares of the  dissenting shareholder in
    that it:

           (1) alters or abolishes a preferential right of the shares;

           (2)  creates,  alters,  or  abolishes  a  right  in  respect  of  the
       redemption of the shares, including a provision respecting a sinking fund
       for the redemption or repurchase of the shares;

           (3)  alters  or abolishes  a preemptive  right of  the holder  of the
       shares to  acquire shares,  securities other  than shares,  or rights  to
       purchase shares or securities other than shares;

           (4)  excludes  or limits  the right  of  a shareholder  to vote  on a
       matter, or to  cumulate votes,  except as the  right may  be excluded  or
       limited  through  the  authorization  or  issuance  of  securities  of an
       existing or new class or series with similar or different voting  rights;
       except that an amendment to the articles of an issuing public corporation
       that  provides that  section 302A.671 does  not apply to  a control share
       acquisition does not give rise to the right to obtain payment under  this
       section;

        (b)   A  sale,  lease,   transfer,  or  other   disposition  of  all  or
    substantially all of  the property and  assets of the  corporation, but  not
    including  a transaction  permitted without shareholder  approval in section
    302A.661, subdivision  1,  or  a disposition  in  dissolution  described  in
    section  302A.725, subdivision 2, or a disposition pursuant to an order of a
    court,  or  a  disposition  for  cash   on  terms  requiring  that  all   or
    substantially  all of the net proceeds  of disposition be distributed to the
    shareholders in accordance with their  respective interests within one  year
    after the date of disposition;

        (c)  A plan of merger, whether under this chapter or under chapter 322B,
    to which the corporation is a party, except as provided in subdivision 3;

        (d) A plan  of exchange,  whether under  this chapter  or under  chapter
    322B,  to which the corporation  is a party as  the corporation whose shares
    will be  acquired  by  the  acquiring corporation,  if  the  shares  of  the
    shareholder are entitled to be voted on the plan; or

        (e) Any other corporate action taken pursuant to a shareholder vote with
    respect  to which the articles, the bylaws,  or a resolution approved by the
    board directs  that dissenting  shareholders may  obtain payment  for  their
    shares.

    Subd.  2.    Beneficial  owners.    (a)    A  shareholder  shall  not assert
dissenters' rights as to less than all  of the shares registered in the name  of
the  shareholder, unless the shareholder dissents with respect to all the shares
that are beneficially owned by another person but registered in the name of  the
shareholder and discloses the name and address of each beneficial owner on whose
behalf  the shareholder  dissents. In  that event,  the rights  of the dissenter
shall be determined as if the shares  as to which the shareholder has  dissented
and the other shares were registered in the names of different shareholders.

                                      M-1
<PAGE>
    (b)  A beneficial  owner of  shares who  is not  the shareholder  may assert
dissenters' rights  with respect  to shares  held on  behalf of  the  beneficial
owner,  and shall be treated as a dissenting shareholder under the terms of this
section and section 302A.473, if the beneficial owner submits to the corporation
at the time of or  before the assertion of the  rights a written consent of  the
shareholder.

    Subd.  3.   Rights not  to apply.   Unless  the articles,  the bylaws,  or a
resolution approved by the board otherwise provide, the right to obtain  payment
under  this section does not apply to a shareholder of the surviving corporation
in a merger, if the  shares of the shareholder are  not entitled to be voted  on
the merger.

    Subd.  4.  Other rights.  The shareholders of a corporation who have a right
under this section to obtain payment for their shares do not have a right at law
or in equity to have a corporate action described in subdivision 1 set aside  or
rescinded,  except when  the corporate action  is fraudulent with  regard to the
complaining shareholder or the  corporation. (Last amended by  Ch. 417, L.  '94,
eff. 8-1-94.)

    302A.473   PROCEDURES  FOR ASSERTING  DISSENTERS' RIGHTS.--   Subdivision 1.
Definitions: (a)  For  purposes of  this  section,  the terms  defined  in  this
subdivision have the meanings given them.

    (b)  "Corporation" means the issuer of the shares held by a dissenter before
the corporate  action referred  to in  section 302A.471,  subdivision 1  or  the
successor by merger of that issuer.

    (c)  "Fair  value  of  the  shares"  means the  value  of  the  shares  of a
corporation immediately  before  the  effective date  of  the  corporate  action
referred to in section 302A.471, subdivision 1.

    (d)  "Interest" means interest commencing five days after the effective date
of the corporate action referred to in section 302A.471, subdivision 1 up to and
including the date of payment, calculated at the rate provided in section 549.09
for interest on verdicts and judgments.

    Subd. 2.  Notice of action.  If a corporation calls a shareholder meeting at
which any action  described in section  302A.471, subdivision 1  is to be  voted
upon,  the notice of the  meeting shall inform each  shareholder of the right to
dissent and shall  include a copy  of section  302A.471 and this  section and  a
brief description of the procedure to be followed under these sections.

    Subd.  3.  Notice of dissent.  If  a proposed action must be approved by the
shareholders, a shareholder who wishes to exercise dissenters' rights must  file
with  the corporation before the vote on the proposed action a written notice of
intent to demand the fair value of the shares owned by the shareholder and  must
not vote the shares in favor of the proposed action.

    Subd.  4.  Notice of  procedure; deposit of shares.   (a) After the proposed
action has been approved by the  board and, if necessary, the shareholders,  the
corporation  shall send to all shareholders who have complied with subdivision 3
and to all shareholders entitled to dissent if no shareholder vote was required,
a notice that contains:

        (1) The  address to  which  a demand  for  payment and  certificates  of
    certificated  shares must be sent in order to obtain payment and the date by
    which they must be received;

        (2) Any  restrictions on  transfer of  uncertificated shares  that  will
    apply after the demand for payment is received;

        (3)  A form to be used to certify  the date on which the shareholder, or
    the beneficial owner on whose behalf the shareholder dissents, acquired  the
    shares or an interest in them and to demand payment; and

        (4)  A copy of section 302A.471 and this section and a brief description
    of the procedures to be followed under these sections.

                                      M-2
<PAGE>
    (b) In  order  to  receive  the  fair value  of  the  shares,  a  dissenting
shareholder  must demand payment and deposit  certificated shares or comply with
any restrictions on transfer of uncertificated  shares within 30 days after  the
notice  was given, but the  dissenter retains all other  rights of a shareholder
until the proposed action takes effect.

    Subd. 5.  Payment; return of shares.   (a) After the corporate action  takes
effect,  or after the corporation receives a valid demand for payment, whichever
is later, the  corporation shall remit  to each dissenting  shareholder who  has
complied  with subdivisions 3 and  4 the amount the  corporation estimates to be
the fair value of the shares, plus interest, accompanied by:

        (1) the corporation's closing balance sheet and statement of income  for
    a  fiscal year ending not  more than 16 months  before the effective date of
    the corporate action, together with  the latest available interim  financial
    statements;

        (2) an estimate by the corporation of the fair value of the shares and a
    brief description of the method used to reach the estimate; and

        (3) a copy of section 302A.471 and this section, and a brief description
    of the procedure to be followed in demanding supplemental payment.

    (b)  The corporation may withhold the  remittance described in paragraph (a)
from a person who was  not a shareholder on the  date the action dissented  from
was first announced to the public or who is dissenting on behalf of a person who
was  not a  beneficial owner on  that date.  If the dissenter  has complied with
subdivisions 3  and  4, the  corporation  shall  forward to  the  dissenter  the
materials  described in paragraph (a), a statement of the reason for withholding
the remittance, and an offer  to pay to the dissenter  the amount listed in  the
materials if the dissenter agrees to accept that amount in full satisfaction.

    The  dissenter may decline the offer and demand payment under subdivision 6.
Failure to do  so entitles  the dissenter  only to  the amount  offered. If  the
dissenter makes demand, subdivisions 7 and 8 apply.

    (c)  If the corporation fails to remit payment within 60 days of the deposit
of certificates or  the imposition  of transfer  restrictions on  uncertificated
shares,  it  shall return  all deposited  certificates  and cancel  all transfer
restrictions. However, the corporation may again give notice under subdivision 4
and require deposit or restrict transfer at a later time.

    Subd. 6.  Supplemental  payment; demand.  If  a dissenter believes that  the
amount  remitted under subdivision 5  is less than the  fair value of the shares
plus interest, the dissenter may give  written notice to the corporation of  the
dissenter's  own estimate of the fair value of the shares, plus interest, within
30 days after  the corporation  mails the  remittance under  subdivision 5,  and
demand payment of the difference. Otherwise, a dissenter is entitled only to the
amount remitted by the corporation.

    Subd.  7.   Petition; determination.   If the corporation  receives a demand
under subdivision 6, it shall, within 60 days after receiving the demand, either
pay to the dissenter  the amount demanded  or agreed to  by the dissenter  after
discussion  with the corporation or file in court a petition requesting that the
court determine the fair value of the shares, plus interest. The petition  shall
be  filed in  the county in  which the  registered office of  the corporation is
located, except  that a  surviving foreign  corporation that  receives a  demand
relating  to the  shares of  a constituent  domestic corporation  shall file the
petition in the county in this state in which the last registered office of  the
constituent  corporation was  located. The  petition shall  name as  parties all
dissenters who  have demanded  payment  under subdivision  6  and who  have  not
reached  agreement with the corporation. THE CORPORATION SHALL, AFTER FILING THE
PETITION, SERVE ALL PARTIES WITH  A SUMMONS AND COPY  OF THE PETITION UNDER  THE
RULES OF CIVIL PROCEDURE. NONRESIDENTS OF THIS STATE MAY BE SERVED BY REGISTERED
OR  CERTIFIED MAIL  OR BY  PUBLICATION AS PROVIDED  BY LAW.  EXCEPT AS OTHERWISE
PROVIDED,  THE  RULES  OF  CIVIL   PROCEDURE  APPLY  TO  THIS  PROCEEDING.   The
jurisdiction  of  the court  is  plenary and  exclusive.  The court  may appoint
appraisers,

                                      M-3
<PAGE>
with powers and authorities the court  deems proper, to receive evidence on  and
recommend  the amount of the fair value of the shares. The court shall determine
whether the shareholder or shareholders in question have fully complied with the
requirements of this section, and shall determine the fair value of the  shares,
taking  into account any and  all factors the court  finds relevant, computed by
any method or combination of methods that the court, in its discretion, sees fit
to use, whether or not used by the corporation or by a dissenter. The fair value
of the  shares  as determined  by  the court  is  binding on  all  shareholders,
wherever  located. A dissenter is entitled to judgment IN CASH for the amount by
which the fair value of  the shares as determined  by the court, plus  interest,
exceeds  the amount,  if any,  remitted under  subdivision 5,  but shall  not be
liable to the corporation for the amount,  if any, by which the amount, if  any,
remitted  to the  dissenter under  subdivision 5 exceeds  the fair  value of the
shares as determined by the court, plus interest.

    Subd. 8.  Costs; fees;  expenses.  (a) The  court shall determine the  costs
and  expenses  of a  proceeding under  subdivision  7, including  the reasonable
expenses and compensation of  any appraisers appointed by  the court, and  shall
assess  those costs and expenses against  the corporation, except that the court
may assess part or  all of those  costs and expenses  against a dissenter  whose
action  in  demanding payment  under  subdivision 6  is  found to  be arbitrary,
vexatious, or not in good faith.

    (b)  If  the  court  finds  that  the  corporation  has  failed  to   comply
substantially  with this section, the court may  assess all fees and expenses of
any experts or attorneys as the  court deems equitable. These fees and  expenses
may also be assessed against a person who has acted arbitrarily, vexatiously, or
not  in good  faith in bringing  the proceeding, and  may be awarded  to a party
injured by those actions.

    (c) The court may award, in its discretion, fees and expenses to an attorney
for the dissenters out of  the amount awarded to  the dissenters, if any.  (Last
amendment by Ch. 17, L. '93, eff. 8-1-93.)

    In  our  opinion, the  accompanying balance  sheet  presents fairly,  in all
material respects, the financial position  of Northern Power Wisconsin Corp.  (a
wholly-owned  subsidiary of Northern States Power  Company) at August 4, 1995 in
conformity  with  generally  accepted  accounting  principles.  This   financial
statement  is the responsibility of the Company's management; our responsibility
is to express  an opinion on  this financial  statement based on  our audit.  We
conducted  our audit  in accordance  with generally  accepted auditing standards
which require that we plan and perform the audit to obtain reasonable  assurance
about  whether the  financial statements are  free of  material misstatement. An

disclosures  in the  financial statements,  assessing the  accounting principles
used and significant estimates  made by management,  and evaluating the  overall
financial   statement  presentation.  We  believe  that  our  audit  provides  a
reasonable basis for the opinion expressed above.

                             NOTE TO BALANCE SHEET

ORGANIZATION OF NORTHERN POWER WISCONSIN CORP.

    Northern  Power Wisconsin  Corp., a  Wisconsin corporation  ("New NSP"), was
formed on  April  27, 1995  for  purposes  of facilitating  the  merger  between
Northern  States Power  Company, a  Minnesota corporation  ("NSP") and Wisconsin
Energy Corporation, a Wisconsin corporation ("WEC").  New NSP has, and prior  to
the  mergers described below will have, no operations, except as contemplated by
the Amended and  Restated Agreement and  Plan of  Merger dated as  of April  28,
1995,  by and among NSP, WEC, New NSP and WEC Sub Corp., as amended and restated
as of July 26, 1995 (the "Merger Agreement"). NSP is the only shareholder of New
NSP. Pursuant to the Merger Agreement,  during the merger process, New NSP  will
acquire  certain utility  assets currently owned  by NSP  and NSP-Wisconsin. The
Articles of  Incorporation  of New  NSP  will  be amended,  effective  upon  the
consummation  of the mergers, to change the  name of New NSP to "Northern States
Power Company." The  principal executive  office of New  NSP is  located at  414
Nicollet Mall, Minneapolis, Minnesota 55401.

    The  Merger  Agreement  provides  that  NSP  shall  cause  the  Articles  of
Incorporation of New NSP to be amended and restated prior to the consummation of
the mergers to increase the par value of New NSP common stock to $2.50, and that
of New NSP preferred stock to $100, and to increase the authorized shares of New
NSP common  stock  to  160,000,000  and  that of  New  NSP  preferred  stock  to
7,000,000.  The Merger Agreement  provides for: (i)  the merger of  NSP with and
into New NSP pursuant to which (a)  each issued and outstanding share of  common
stock,  par value $2.50  per share, of  NSP ("NSP Common  Stock") (except shares
held by NSP  shareholders who  perfect dissenters' rights  with respect  thereto
("NSP  Dissenting Shares"))  will be cancelled  and converted into  one share of
common stock, par value $2.50 per share, of New NSP ("New NSP Common Stock") and
(b) each issued and outstanding share  of cumulative preferred stock, par  value
$100  per share, of  NSP ("NSP Preferred Stock")  (except NSP Dissenting Shares)
will be cancelled and  converted into one share  of cumulative preferred  stock,
par  value $100  per share, of  New NSP  ("New NSP Preferred  Stock") with terms
(including  dividend  rates)  and  designations  under  New  NSP's  Articles  of
Incorporation  identical to those of the  cancelled share of NSP Preferred Stock
under NSP's existing Restated Articles of Incorporation; and (ii) the merger  of
WEC  Sub Corp.  with and  into New  NSP pursuant  to which  (a) each  issued and
outstanding share of New NSP Common  Stock will be cancelled and converted  into
1.626  shares of common stock, par value $.01 per share, of Primergy Corporation
and (b) each issued and outstanding share of New NSP Preferred Stock will remain
outstanding and shall  be unchanged thereby  (except for any  shares of New  NSP
Common Stock and New NSP Preferred Stock owned directly or indirectly by New NSP
and  WEC,  which  will  be  cancelled  and  will  not  be  converted  or  remain
outstanding).

                                       OF
                         NORTHERN POWER WISCONSIN CORP.
                           (A WISCONSIN CORPORATION)

                                   ARTICLE 1.
                  NAME, REGISTERED OFFICE, AND CORPORATE SEAL

    SECTION 1.  The name of the Company is NORTHERN POWER WISCONSIN CORP.

    SECTION 2.  The location and post office address of its registered office is
44 East Mifflin Street, Madison, Wisconsin 53703.

    SECTION  3.  The Company may establish  and maintain an office or offices at
such other places  within or  without the  State of  Wisconsin as  the Board  of
Directors may from time to time determine.

    SECTION  4.  The corporate seal of  the Company shall have inscribed thereon
the name of the Company and the words "Corporate Seal - Wisconsin 1995". In lieu
of causing the corporate  seal to be impressed  upon any bond, debenture,  note,
contract,  or other instrument required or authorized to bear the corporate seal
of the Company, the Board of Directors may authorize a facsimile of said seal to
be engraved or printed thereon, and such facsimile, when so engraved or printed,
shall be and constitute the corporate seal of the Company for such purpose.

                                   ARTICLE 2.
                               BOARD OF DIRECTORS

    SECTION 1.  The business  and property of the  Company shall be managed  and
controlled  by a  Board composed of  from three (3)  to fifteen (15),  as may be
determined by the Board of Directors  or by shareholders in accordance with  the
provisions  of this Article. The number of  directors shall be determined by the
Board of Directors, and if the Board fails to make such determination, then  the
number may be determined by the shareholders at any annual or special meeting of
shareholders.

    SECTION  2.  A director  shall hold office until  the next annual meeting of
the shareholders and until his successor is elected and qualifies. At the annual
meeting of shareholders in 1996, the Board of Directors of the Company shall  be
divided  into three classes as nearly equal in number as possible, with the term
of office of one class expiring each year. Directors in Class I shall be elected
to hold office until the next  succeeding annual meeting; directors in Class  II
shall  be elected to hold office until the second succeeding annual meeting; and
directors in  Class  III  shall  be  elected to  hold  office  until  the  third
succeeding  annual meeting,  and, in  each of  the foregoing  cases, until their
respective successors are duly  elected and qualify.  At each subsequent  annual
meeting  of shareholders,  the successors to  the class of  directors whose term
shall then expire shall be elected by the shareholders to hold office until  the
third  succeeding annual meeting, and until their respective successors are duly
elected and qualify.  If, at any  meeting of shareholders,  commencing with  the
annual  meeting of shareholders in 1996, due to the initiation of the classified
method of electing directors or  due to a vacancy or  vacancies on the Board  of
Directors,  or otherwise, directors  of more than  one class are  to be elected,
each class of  directors to be  elected at  the meeting shall  be nominated  and
voted for in a separate election.

    SECTION  3.   During  the intervals  between annual  meetings the  number of
directors may be increased, and may be decreased by the number of vacancies then
existing, by the Board of Directors, within the limitations of Section 1 of this
Article, and in case of  any such increase the Board  may fill the vacancies  so
created.  No  decrease in  the Board  shall  shorten the  term of  any incumbent
director.

                                      O-1
<PAGE>
    SECTION 4.   Vacancies  in  the Board  of Directors  may  be filled  by  the
remaining members of the Board though less than a quorum. Each person so elected
to  fill a vacancy shall remain a director  for the unexpired term in respect of
which such vacancy occurred and until his successor is elected and qualifies.

    SECTION 5.  In addition to the powers and authority expressly conferred upon
them by these Bylaws, the Board of Directors may exercise all such powers and do
all such  acts and  things as  may  be exercised  or done  by the  Company,  but
subject,   nevertheless,  to  the   provisions  of  statute,   the  Articles  of
Incorporation, and these Bylaws.

    SECTION 6.  Without  limiting the general powers  conferred by Section 5  of
this  Article,  and  other  powers  conferred by  statute,  by  the  Articles of
Incorporation, and by  these Bylaws, it  is hereby expressly  declared that  the
Board of Directors shall have the following powers, that is to say:

        (a)  To  purchase or  otherwise acquire  for  the Company  any property,
    rights, or privileges which the Company  is authorized to acquire, for  such
    consideration and on such terms and conditions as it deems proper.

        (b)  At its discretion to pay for any property or rights acquired by the
    Company either wholly or partly in money or in stock, bonds, debentures,  or
    other securities or property of the Company.

        (c) To appoint any person or persons to accept and hold in trust for the
    Company any property belonging to the Company, or in which it is interested,
    and to do and execute all such things as may be requisite in relation to any
    such trust.

        (d)  To in  any manner  aid, facilitate,  and assist,  in behalf  of the
    Company,   in   the   construction,   extension,   improvement,   equipment,
    maintenance,  and  operation of  any  electric light  plant  or distribution
    system, electric transmission or distribution lines, steam plant for heating
    and power or  distribution system, natural,  manufactured, mixed, or  liquid
    petroleum  gas plant  or distribution system,  gas or oil  pipe lines, barge
    lines, coal mines, water  power or water plants,  or telephone systems,  and
    all  property and things appurtenant to or used in connection therewith, and
    for that purpose to  use the cash  or capital stock  or other securities  or
    obligations  of the Company  to buy, refund,  guarantee, or otherwise secure
    the indebtedness  against  any  such properties  and  guarantee  the  bonds,
    debentures,  indebtedness,  dividends,  contracts, or  other  obligations of
    firms or other corporations.

        (e) To authorize  one or  more officers, on  behalf of  the Company,  to
    borrow   money,  make  and  issue  notes,  bonds,  and  other  evidences  or
    indebtedness, execute  mortgages,  deeds  of trust,  trust  agreements,  and
    instruments  of pledge or hypothecation, and  do all other acts necessary to
    effectuate the same.

        (f) To designate  the persons  authorized, on the  Company's behalf,  to
    make and sign notes, receipts, acceptances, endorsements, drafts, checks, or
    other  orders  for  the payment  of  money, releases,  contracts,  and other
    instruments, and,  when  appropriate,  to  make provision  for  the  use  of
    facsimile signatures thereon.

        (g)  To designate  the persons authorized,  on the  Company's behalf, to
    vote upon or to  assign and transfer  any shares of  stock, bonds, or  other
    securities of other corporations held by the Company.

    SECTION  7.    Meetings of  the  Board of  Directors  shall be  held  at the
registered office of the Company, but the chairman of the Board, the  President,
or  a majority  of the Board  may from time  to time designate  some other place
within or without the State of Wisconsin for the holding of any such meeting  or
meetings.

    SECTION  8.  Regular meetings of the Board of Directors may be held, without
notice, at such times as shall be determined from time to time by resolution  of
the Board.

    SECTION  9.   Special  meetings  of the  Board  of Directors  shall  be held
whenever called by the Chairman of the Board, by the President, or by a majority
of the Board.

    SECTION 10.  The  Secretary shall give  notice of a  special meeting of  the
Board  of Directors to each  director, either by mail  or by telegraph, at least
two days before  said meeting.  Any director may  in writing,  either before  or
after  the meeting, waive  notice thereof; and, without  notice, any director by
his attendance at any meeting shall be deemed to have waived notice.

    SECTION 11.  Unless otherwise indicated  in the notice thereof, any and  all
business may be transacted at a special meeting.

    SECTION  12.  At the  first regular meeting following  the annual meeting of
the shareholders,  the  Board of  Directors  shall  elect the  officers  of  the
Company,  who shall  hold office  for one  year and  until their  successors are
elected. Any office not filled at such  meeting may be filled at any  subsequent
meeting of the Board.

    SECTION  13.  A majority of the Board of Directors shall constitute a quorum
for the  transaction of  business, and  the acts  of majority  of the  directors
present at a meeting at which a quorum is present shall be the acts of the Board
of  Directors, except as  may be otherwise specifically  provided by statute, by
the Articles of Incorporation, or by these Bylaws. At any meeting at which there
is less than  a quorum  present, the director  or directors  present shall  have
power by a majority vote to adjourn the meeting from time to time without notice
other  than announcement  at the  meeting. At any  adjourned meeting  at which a
quorum is  present  any  business  may  be  transacted  which  might  have  been
transacted by a quorum of the directors at the meeting as originally convened.

    SECTION  14.  Any action which  might be taken at a  meeting of the Board of
Directors may be taken without a meeting if done in writing signed by all of the
directors.

    SECTION 15.  Inasmuch  as the directors  of the Company  may have large  and
diversified  business  interests  and  are likely  to  be  connected  with other
corporations with which  this Company may  have business dealings  from time  to
time,  no  contract or  other  transaction between  this  Company and  any other
corporation shall be  affected by the  fact that directors  of this Company  are
interested  in, or are directors or officers of, such other corporation, and any
director individually may be a party to or may be interested in any contract  or
transaction  of this  Company, provided  that any  such contract  or transaction
referred to in this section shall be approved or be ratified by the  affirmative
vote of a majority of the members of the Board not so interested.

    SECTION  16.   The Board of  Directors may  provide for the  payment to each
director of a fixed annual  fee, a fixed fee for  attendance at each meeting  of
the  Board or of any committee thereof,  or a combination of the foregoing fees,
and the expenses of each director for attendance at each meeting of the Board or
of any committee thereof; provided, however, that no part of any such fee  shall
be  paid to any director during any year when there is in effect a prior written
request from such director  that all or a  portion of said fees  not be paid  to
him. Nothing herein shall be construed to preclude any director from serving the
Company  in  any  other  capacity  as  an  officer  or  otherwise  and receiving
compensation therefor.

                                   ARTICLE 3.

offices,  except those of President and Vice  President, may be held by the same

    (b) At its discretion,  the Board of Directors  at any time, by  resolution,
may  recognize  the outstanding  services  of an  individual  to the  Company by
conferring upon him the honorary title of "Honorary Chairman of the Board", such
title to  be held  for such  limited period  of time,  or for  life, as  may  be
determined  by the  Board. Except when  used in  Article 4 of  these Bylaws, the
words "director", "directors",  "Board of  Directors", "members  of the  Board",

of "Chairman Emeritus", such title to be  held for such limited period of  time,
or  for life,  as may be  determined by  the Board. The  action of  the Board of
Directors in  conferring the  honorary title  of "Chairman  Emeritus" upon  such

corporation.  The President shall report to the  Board all matters within his or

may  be required; and shall perform all  such duties as are properly required by

    SECTION 4.   The Vice Presidents  shall be  vested with all  the powers  and
shall  perform all the  duties of the  President in the  order designated by the

required by statute, by  the Articles of Incorporation,  or by these Bylaws.  He

of Directors and shall record the proceedings  of all such meetings in the  book

    SECTION 1.   Every  certificate of  shares shall  be numbered  and shall  be
entered  on the books of the Company as it  is issued. It shall be signed by the
Chairman of the Board, President or a Vice President and by the Secretary or  an
Assistant Secretary and shall bear the corporate seal, but when a certificate is

satisfactory to the Treasurer.

    SECTION  4.  The Company shall be entitled  to treat the holder of record of
any share or  shares as the  holder in fact  thereof and shall  not be bound  to

thereof, save as expressly provided by statute.

    SECTION  5.  The Board  of Directors shall have  authority to appoint one or
more registrars or  transfer agents  for any  or all  classes of  shares of  the
Company,  to make such rules and regulations as it may deem expedient concerning
the issuance, registration,  and transfer  of such  shares, and  to remove  such
registrars  or transfer agents, or any of them, and appoint another or others in
its or their stead. A certificate of shares  of any class for which one or  more
registrars  or transfers  agents shall  have been  appointed shall  not be valid
until countersigned by a registrar or a transfer agent, or both, as the case may
be.

                                  SHAREHOLDERS

    SECTION 1.  The annual and special meetings of shareholders shall be held at
the registered office of the Company,  but the Board of Directors may  designate
some other place within or without the State of Wisconsin for the holding of any
such  meeting  or meetings.  Written notice  of  each meeting,  of shareholders,
stating the time  and place, and,  in case  of a special  meeting, the  purpose,
shall  be given by  the Secretary to  each shareholder entitled  to vote at such
meeting, not less than ten days prior to the date of such meeting.

    SECTION 2.  The Chairman of the  Board shall preside at all meetings of  the
shareholders,  and in his absence or disability  or at his request the President
shall preside, and in  the absence or  disability of both  said officers a  Vice
President shall preside.

    SECTION  3.   The  Board of  Directors  may, within  the limitations  of the
statute, fix a  record date for  the determination of  shareholders entitled  to
receive  notice of and to vote at any meeting of shareholders, and a record date
for the  determination  of shareholders  entitled  to receive  payments  of  any
dividend  or  distribution or  allotment of  rights or  to exercise  rights with
respect to any  change, conversion,  or exchange of  shares, and  may close  the
books of the Company against the transfer of shares during the whole or any part
of the period so fixed.

    SECTION 4.  The annual meeting of shareholders shall be held on the date and
time and at the location designated by the Board of Directors.

                                      O-6
<PAGE>
    SECTION  5.  Special meetings of the  shareholders may be called and held as
provided by Wisconsin Statutes.

    SECTION 6.   The holders of  a majority of  the voting power  of the  shares
issued  and outstanding  and entitled  to vote, present  in person  or by proxy,
shall constitute a quorum at all meetings of shareholders for the transaction of
business,  except  as  otherwise  provided  by  statute,  by  the  Articles   of
Incorporation,  or by these Bylaws. In the  absence of a quorum, any meeting may
be adjourned from time  to time. The  shareholders present at  a duly called  or
held  meeting at  which a  quorum is present  may continue  to transact business
until adjournment,  notwithstanding the  withdrawal  of enough  shareholders  to
leave less than a quorum.

    SECTION  7.  At each meeting of shareholders every shareholder of record, or
his legal representatives, at the date fixed  by the Board of Directors for  the
determination  of the persons entitled to vote at a meeting of shareholders, or,
if no date has been so fixed, then  at the close of the thirtieth day  preceding
the  date of the meeting, shall be entitled at such meeting to one vote for each
share standing in his name on the books of the Company and such additional votes
for such shares  as may  be provided  for by  the Articles  of Incorporation.  A
shareholder  may cast his vote in person or by proxy. The appointment of a proxy
shall be in writing filed with the Secretary at or before the meeting. The  vote
for  directors,  and, upon  the demand  of  any shareholder,  the vote  upon any
question before the meeting, shall be by ballot. All elections shall be had  and
all questions decided by a plurality vote.

    SECTION  8.  In advance of any  meeting of shareholders, the Chairman of the
Board shall  appoint three  or more  inspectors  of election,  who need  not  be
shareholders,  as to the matters to be submitted  to a vote at any such meeting,
or any adjournment thereof. The inspectors  of election when so appointed  shall
take  charge of all proxies and ballots and shall determine the number of shares
outstanding, the voting power  of each, the shares  represented at the  meeting,
and  the existence of a  quorum. They shall determine  all questions relating to
the qualifications of voters, the authenticity, validity, and effect of proxies,
and the acceptance or rejection of  votes, challenges, and questions arising  in
any  way in connection with the right to vote and the counting and tabulation of
such votes. They shall determine the number of votes cast for any office or  for
or  against any  proposal, and  shall determine  and report  the results  to the
meeting. The inspectors shall take an  oath that they will perform their  duties
impartially,   in  good  faith,  and  to  the  best  of  their  ability  and  as
expeditiously as  is practical.  If,  for any  reason, an  inspector  previously
appointed  shall fail  to attend or  refuse or  be unable to  serve, the vacancy
shall be  filled by  the  Chairman of  the Board  in  advance of  convening  the
meeting,  or at the meeting by the person acting as Chairman. Each report of the
inspectors shall be in  writing and signed  by the inspectors.  The report of  a
majority shall be the report of the inspectors.

    SECTION  9.    (a)    At  any  annual  meeting  or  any  special  meeting of
shareholders, only such  business shall  be conducted, and  only such  proposals
shall  be acted upon as shall have been brought before the meeting (i) by, or at
the direction of,  the Board of  Directors, or  (ii) by any  shareholder of  the
Company  who complies with  the requirements of Rule  14a-8 under the Securities
Exchange Act of 1934, as amended, or (iii) by any shareholder of the Company who
complies with the notice procedures set forth in this Section 9.

    (b) For  a proposal  to be  properly  brought before  an annual  or  special
meeting  by a shareholder, the shareholder must have given timely notice thereof
in writing to the Secretary of the Company. To be timely, a shareholder's notice
must be delivered to, or mailed and received at, the principal executive offices
of the Company not  less than twenty  (20) days nor more  than ninety (90)  days
prior  to the scheduled  meeting, regardless of  any postponements, deferrals or
adjournments of that meeting  to a later date;  provided, however, that if  less
than  thirty (30)  days' notice or  prior public  disclosure of the  date of the
scheduled meeting is  given or made,  notice by the  shareholder, to be  timely,
must  be so delivered  or received not later  than the close  of business on the
tenth (10th) day following the earlier of  the date on which such notice of  the
date  of  the scheduled  meeting  was mailed  or the  day  on which  such public
disclosure was made.

                                      O-7
<PAGE>
    (c) A  shareholder's notice  to the  Secretary shall  set forth  as to  each
matter  the  shareholder  proposes  to  bring before  the  meeting  (i)  a brief
description of the  proposal desired to  be brought before  the meeting and  the
reasons  for conducting such business at the meeting, (ii) the name and address,
as they  appear  on the  Company's  books,  of the  shareholder  proposing  such
business  and any other  shareholder known by such  shareholder to be supporting
such proposal who is the record or beneficial owner (as such term is defined  in
Rule  13d-3 or 13d-5 under  the Securities Exchange Act  of 1934, as amended) of
any equity security of the Company, (iii) the class and number of shares of  the
Company's  equity securities which are beneficially owned (as defined above) and
owned of  record by  the  shareholder giving  the notice  on  the date  of  such
shareholder notice and by any other record or beneficial owners of the Company's
equity  securities known by  such shareholder to be  supporting such proposal on
the date of such shareholder notice, and (iv) any financial or other interest of
the shareholder in such proposal.

    (d) The Chairman of the Board may reject any shareholder proposal not timely
made in accordance  with the terms  of this Section  9. If the  Chairman of  the
Board  determines that the information provided in shareholder's notice does not
satisfy the  informational  requirements  of  this Section  9  in  any  material
respect,  the Secretary of the Company shall promptly notify such shareholder of
the deficiency in the notice. The shareholder shall have an opportunity to  cure
the  deficiency by providing additional information to the Secretary within such
period of time, not to exceed five (5) days from the date such deficiency notice
is given  to the  shareholder, as  the Chairman  of the  Board shall  reasonably
determine. If the deficiency is not cured within such period, or if the Chairman
of  the  Board  determines  that  the  additional  information  provided  by the
shareholder, together with the information previously provided, does not satisfy
the requirements of this Section 9 in any material respect, then the Chairman of
the Board may reject such shareholder's  proposal. The Secretary of the  Company
shall  notify a shareholder  in writing whether such  person's proposal has been
made in accordance with the time and information requirements of this Section 9.
Notwithstanding the procedures set forth in  this paragraph, if the Chairman  of
the  Board does not make  a determination as to  the validity of any shareholder
proposal under Section 9(c),  the chairman of the  annual or special meeting  of
shareholders  shall determine and declare at the meeting whether the shareholder
proposal was made in accordance with the terms of Section 9. If the chairman  of
such  meeting determines that a shareholder  proposal was not made in accordance
with the terms of this Section 9, he or she shall so declare at the meeting  and
any such proposal shall not be acted upon at the meeting.

    (e)  This  provision shall  not prevent  the  consideration and  approval or
disapproval at any meeting of reports  of officers, directors and committees  of
the  Board of Directors, but,  in connection with such  reports, no new business
shall be acted upon at such meeting unless stated, filed and received as  herein
provided.

                   INFORMATION NOT REQUIRED IN THE PROSPECTUS

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

    Each registrant is incorporated under the Wisconsin Business Corporation Law
(the "WBCL").

    Under  Section  180.0851(1)  of the  WBCL,  each registrant  is  required to
indemnify a director or officer, to the extent such person is successful on  the
merits  or otherwise in the defense of a proceeding, for all reasonable expenses
incurred in the proceeding if  such person was a party  because he or she was  a
director  or officer of such registrant. In  all other cases, each registrant is
required by  Section 180.0851(2)  to  indemnify a  director or  officer  against
liability  incurred in a proceeding to which  such person was a party because he
or she was a  director or officer  of such registrant,  unless it is  determined
that  he or she breached or failed to perform a duty owed to such registrant and
the breach or  failure to  perform constitutes: (i)  a willful  failure to  deal
fairly  with such registrant or its shareholders  in connection with a matter in
which the  director or  officer has  a  material conflict  of interest;  (ii)  a
violation  of criminal law, unless the  director or officer had reasonable cause
to believe his or her conduct was  lawful or no reasonable cause to believe  his
or  her conduct  was unlawful;  (iii) a transaction  from which  the director or
officer derived an improper personal profit; or (iv) willful misconduct. Section
180.0858(1)  provides  that,  subject  to  certain  limitations,  the  mandatory
indemnification   provisions   do   not  preclude   any   additional   right  to
indemnification or allowance  of expenses that  a director or  officer may  have
under  a company's articles of incorporation, bylaws, any written agreement or a
resolution of the Board of Directors or shareholders.

    Section 180.0859 of the WBCL  provides that it is  the public policy of  the
State  of Wisconsin to require or  permit indemnification, allowance of expenses
and insurance to  the extent required  or permitted under  Sections 180.0850  to
180.0858 of the WBCL, for any liability incurred in connection with a proceeding
involving  a federal or state statute,  rule or regulation regulating the offer,
sale or purchase of securities.

    Section 180.0828  of the  WBCL  provides that,  with certain  exceptions,  a
director  is  not  liable to  a  corporation,  its shareholders,  or  any person
asserting rights on behalf of the corporation or its shareholders, for  damages,
settlements, fees, fines, penalties or other monetary liabilities arising from a
breach  of, or  failure to perform,  any duty  resulting solely from  his or her
status as a  director, unless  the person  asserting liability  proves that  the
breach or failure to perform constitutes any of the four exceptions to mandatory
indemnification under Section 180.0851(1) referred to above.

    Under  Section 180.0833  of the  WBCL, directors  of a  company against whom
claims are asserted  with respect to  the declaration of  improper dividends  or
distributions to shareholders or certain other improper acts which they approved
are  entitled to contribution from other directors who approved such actions and
from shareholders who knowingly accepted  an improper dividend or  distribution,
as provided therein.

    Articles  V and VI  of WEC's Bylaws  provide that WEC  will indemnify to the
fullest extent permitted by law any person  who is or was a party or  threatened
to  be made  a party to  any legal  proceeding by reason  of the  fact that such
person is or  was a director  or officer  of WEC, or  is or was  serving at  the
request  of WEC as a director or officer of another enterprise, against expenses
(including attorney  fees),  judgments, fines  and  amounts paid  in  settlement
actually  and reasonably  incurred by the  person in connection  with such legal
proceeding. WEC's Restated Articles of Incorporation and Bylaws do not limit the
indemnification to which directors and officers are entitled under the WBCL.

    Article 4 of New NSP's Bylaws contains provisions for indemnification of its
directors and officers consistent with the provisions of the WBCL.

    Officers and directors of each registrant are covered by insurance  policies
purchased  by such registrant or its parent (in the case of New NSP) under which
they are  insured  (subject  to  exceptions and  limitations  specified  in  the
policies)  against expenses  and liabilities  arising out  of actions,  suits or
proceedings to which they  are parties by  reason of being  or having been  such
directors or officers.

                                      II-1
<PAGE>
    Under  Section 7.5  of the  Merger Agreement,  the parties  have agreed that
Primergy will (a)  indemnify, defend  and hold  harmless to  the fullest  extent
permitted  by applicable  law, the  present and  former officers,  directors and
employees of  each of  the parties  to the  Merger Agreement  or any  subsidiary
against certain liabilities (i) arising out of actions or omissions occurring at
or prior to the Effective Time that are based on or arise out of such service as
an  officer,  director or  employee or  (ii) that  are based  on, arise  from or
pertain to  the  transactions contemplated  by  the Merger  Agreement,  and  (b)
maintain  policies of directors' and officers'  liability insurance for a period
of six  years after  the Effective  Time.  In addition,  to the  fullest  extent
permitted  by law, all existing rights  of indemnification will continue in full
force and effect for not less than  six years from the Effective Time. See  "The
Merger  Agreement --  Indemnification" in  the Joint  Proxy Statement/Prospectus
which forms a part of this Joint Registration Statement.

ITEM 22.  UNDERTAKINGS.

    Each undersigned registrant hereby undertakes as follows:

        (1)  To file, during any period in which offers or sales are being made,
    a post-effective amendment to this registration statement:

        (i) To  include  any prospectus  required  by Section  10(a)(3)  of  the
    Securities Act of 1933;

        (ii)  To reflect in the prospectus any facts or events arising after the
    effective  date  of   the  registration  statement   (or  the  most   recent
    post-effective  amendment thereof) which, individually  or in the aggregate,
    represent  a  fundamental  change  in  the  information  set  forth  in  the
    registration  statement.  Notwithstanding  the  foregoing,  any  increase or
    decrease in  volume of  securities offered  (if the  total dollar  value  of
    securities  offered  would not  exceed that  which  was registered)  and any
    deviation from the low or high  end of the estimated maximum offering  range
    may  be  reflected  in the  form  of  prospectus filed  with  the Commission
    pursuant to Rule  424(b) if,  in the aggregate,  the changes  in volume  and
    price  represent no more than a 20% change in the maximum aggregate offering
    price set  forth in  the  "Calculation of  Registration  Fee" table  in  the
    effective registration statement;

       (iii)  To include  any material information  with respect to  the plan of
    distribution not previously disclosed in  the registration statement or  any
    material change to such information in the registration statement.

        PROVIDED,  HOWEVER, that paragraphs  (1)(i) and (1)(ii)  do not apply if
    the registration statement is on Form  S-3 or Form S-8, and the  information
    required to be included in a post-effective amendment by those paragraphs is
    contained in periodic reports filed by the registrant pursuant to Section 13
    or   Section  15(d)  of  the  Securities  Exchange  Act  of  1934  that  are
    incorporated by reference in the registration statement.

        (2) That,  for  the  purpose  of determining  any  liability  under  the
    Securities  Act of 1933, each such  post-effective amendment shall be deemed
    to be  a  new registration  statement  relating to  the  securities  offered
    therein, and the offering of such securities at that time shall be deemed to
    be the initial BONA FIDE offering thereof.

        (3)  To remove from registration by  means of a post-effective amendment
    any  of  the  securities  being  registered  which  remain  unsold  at   the
    termination of the offering.

                                      II-5
<PAGE>
        (4) That, for purposes of determining any liability under the Securities
    Act  of  1933, each  filing of  the registrant's  annual report  pursuant to
    Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934  (and,
    where  applicable, each filing  of an employee  benefit plan's annual report
    pursuant to Section 15(d)  of the Securities Exchange  Act of 1934) that  is
    incorporated  by reference in the registration  statement shall be deemed to
    be a new registration statement relating to the securities offered  therein,
    and  the offering of such securities at that  time shall be deemed to be the
    initial BONA FIDE offering thereof.

        (5) That prior  to any  public reoffering of  the securities  registered
    hereunder  through use  of a prospectus  which is part  of this registration
    statement, by any person or party who is deemed to be an underwriter  within
    the  meaning  of Rule  145(c), the  issuer  undertakes that  such reoffering
    prospectus will  contain  the  information  called  for  by  the  applicable
    registration  form with respect to reofferings  by persons who may be deemed
    underwriters, in addition to the information  called for by the other  items
    of the applicable form.

        (6)  That every prospectus: (i) that  is filed pursuant to paragraph (5)
    immediately preceding, or  (ii) that  purports to meet  the requirements  of
    Section  10(a)(3) of the Act  and is used in  connection with an offering of
    securities subject to Rule 415, will be  filed as a part of an amendment  to
    the  registration statement  and will  not be  used until  such amendment is
    effective, and that,  for purposes  of determining any  liability under  the
    Securities  Act of 1933, each such  post-effective amendment shall be deemed
    to be  a  new registration  statement  relating to  the  securities  offered
    therein, and the offering of such securities at that time shall be deemed to
    be the initial BONA FIDE offering thereof.

        (7)  Insofar  as  indemnification  for  liabilities  arising  under  the
    Securities  Act  of  1933  may  be  permitted  to  directors,  officers  and
    controlling persons of the registrant pursuant to the provisions referred to
    in  Item 20 of this registration statement, or otherwise, the registrant has
    been advised that in the opinion  of the Securities and Exchange  Commission
    such  indemnification is against  public policy as expressed  in the Act and
    is, therefore, unenforceable. In the event that a claim for  indemnification
    against  such  liabilities  (other than  the  payment by  the  registrant of
    expenses incurred or paid  by a director, officer  or controlling person  of
    the  registrant in the successful defense of any action, suit or proceeding)
    is asserted by such  director, officer or  controlling person in  connection
    with  the securities  being registered, the  registrant will,  unless in the

Wisconsin Energy Corporation

P.O. Box 2949
Milwaukee, Wisconsin 53201

Ladies and Gentlemen:

    We  are providing this opinion in connection with the Registration Statement
of  Wisconsin  Energy  Corporation  ("WEC")  on  Form  S-4  (the   "Registration
Statement")  being  filed under  the  Securities Act  of  1933, as  amended (the
"Act"), with respect to the proposed issuance of up to 114,357,613 shares of WEC
(and, after  the effective  time  of the  Mergers  referred to  below,  Primergy
Corporation) Common Stock, $.01 par value (the "Shares"), to the shareholders of
Northern  States Power Company,  a Minnesota corporation  ("NSP"), in connection
with the statutory merger of NSP with and into Northern Power Wisconsin Corp., a
Wisconsin corporation which is presently a wholly-owned subsidiary of NSP  ("New
NSP"),  followed  immediately  by  the  statutory merger  of  WEC  Sub  Corp., a
Wisconsin corporation which is presently a wholly-owned subsidiary of WEC  ("WEC
Sub"),  with and  into New  NSP (collectively,  the "Mergers"),  pursuant to the
Amended and Restated Agreement and Plan of  Merger, dated as of April 28,  1995,
as  amended and restated as of July 26, 1995, by and among NSP, WEC, New NSP and
WEC Sub  (the "Merger  Agreement"). In  connection with  the Mergers,  WEC  will
change its name to Primergy Corporation.

    We  have examined: (i) WEC's Restated  Articles of Incorporation and Bylaws,
as amended to date and as proposed to be amended in connection with the Mergers;
(ii) the Merger  Agreement, which  is attached  as Annex  A to  the Joint  Proxy
Statement/Prospectus   contained  in  the   Registration  Statement;  (iii)  the
Registration Statement; (iv) corporate proceedings  of WEC and WEC Sub  relating
to  the Merger Agreement and the transactions contemplated thereby; and (v) such
other documents as  we have deemed  necessary in order  to render this  opinion.
Based on the foregoing, it is our opinion that:

       1.  WEC is a corporation duly incorporated and validly existing under the
           laws of the State of Wisconsin.

       2.  When (a) the Registration Statement shall have become effective under
           the  Act, (b) the  Merger Agreement shall have  been duly approved by
    the shareholders  of  NSP  and  WEC  as  contemplated  therein  and  in  the
    Registration  Statement, (c) the  parties shall have  received all necessary
    regulatory approvals  required  to  consummate the  Mergers  and  issue  the
    Shares,  (d) the Mergers shall have been duly consummated in accordance with
    the terms of the Merger  Agreement and the laws  of the States of  Minnesota
    and  Wisconsin and  (e) up  to 114,357,613 Shares  have been  duly issued in
    accordance with the provisions of  the Merger Agreement and such  regulatory
    approvals,  such Shares  will be duly  authorized and  validly issued, fully
    paid and  nonassessable,  subject  to  the  personal  liability  imposed  on
    shareholders by Section 180.0622(2)(b) of the Wisconsin Business Corporation
    Law,  as judicially interpreted,  for debts owing  to employees for services
    performed, but not exceeding  six months service in  any one case.  Although
    Section 180.0622(2)(b) provides that such personal liability of shareholders
    shall  be "to  an amount  equal to  the par  value of  shares owned  by them
    respectively, and to the  consideration for which  their shares without  par
    value  was issued," the Wisconsin Supreme Court, by a split decision without
    a written  opinion,  has  affirmed  a judgment  holding  shareholders  of  a
    corporation  liable under the substantially identical predecessor statute in
    effect prior  to January  1, 1991  (Section 180.40(6))  for unpaid  employee
    wages to an amount equal to the

    consideration  for which their par value  shares were issued rather than the
    shares' lower stated par value. LOCAL 257 OF HOTEL AND RESTAURANT  EMPLOYEES
    AND  BARTENDERS INTERNATIONAL UNION v.  WILSON STREET EAST DINNER PLAYHOUSE,
    INC., 126 Wis. 2d 284, 375 N.W.2d 664 (1985) (affirming the 1983 decision of
    the Circuit Court for Dane County, Wisconsin, in Case No. 82-CV-0023).

    We have not passed upon the actions of the Boards of Directors of either NSP
or New NSP to authorize  the consummation of the  Mergers and have assumed  that
all necessary action has been taken.

    We  hereby  consent to  the  filing of  this opinion  as  an exhibit  to the
Registration Statement and to the reference to our firm under the caption "Legal
Matters" in the Joint Proxy Statement/Prospectus constituting a part thereof. In
giving our consent, we do not admit that we are "experts" within the meaning  of
Section  11 of  the Act,  or that we  are within  the category  of persons whose
consent is required by Section 7 of the Act or the rules and regulations of  the
Securities and Exchange Commission thereunder.

    Larry J. Martin, a partner in our firm, serves as General Counsel of WEC.

                                          Very truly yours,

Re:3,900,000 shares of Cumulative Preferred Stock, Par Value $100 Per Share, of
   Northern Power Wisconsin Corp., a Wisconsin corporation

Ladies and Gentlemen:

    I  am participating in the proceedings  incident to the proposed issuance by
Northern Power Wisconsin Corp., a  Wisconsin corporation (the "Company"), of  up
to  3,900,000 shares of its Cumulative Preferred Stock, par value $100 per share
(the "Shares"). I have examined all records, instruments, and documents which  I
have deemed necessary to examine for the purposes of this opinion, including the
Registration  Statement on Form  S-4 relating to  the Shares to  be filed by the
Company pursuant to the Securities Act of 1933, as amended.

    Based upon the foregoing  and upon my general  familiarity with the  Company
and its affairs, I am of the opinion:

    1.   That the Company  is a duly organized  and validly existing corporation
under the laws of the  State of Wisconsin and that  it is legally qualified  and
authorized to operate and conduct business in the State of Wisconsin.

    2.   When, as  and if the Registration  Statement on Form  S-4 to which this
opinion is  an exhibit  becomes  effective pursuant  to  the provisions  of  the
Securities  Act of  1933, as amended,  all necessary  regulatory and shareholder
approvals have been obtained, the Amended and Restated Articles of Incorporation
of the Company (described in the Registration Statement) have been duly  adopted
and  become effective, the Shares  have been duly issued  and delivered, and the
consideration for the Shares has been duly  received by the Company, all in  the
manner  contemplated by said Registration Statement,  the Shares will be legally
issued, fully  paid, and  (subject to  Section 180.0622(2)(b)  of the  Wisconsin
Business  Corporation Law,  as judicially  interpreted) nonassessable  shares of
preferred stock of the Company.

    I hereby consent to the incorporation of this opinion into said Registration
Statement and the  reference to  me under the  heading "Legal  Matters" in  said
Registration Statement.

Respectfully submitted,

/s/ JOHN P. MOORE, JR.

To the Board of Directors and
  the Stockholders of Wisconsin Energy Corporation:

    In our  opinion, the  consolidated financial  statements listed  under  Item
14(a)  (1) and (2) on  pages 66 and 67  of Wisconsin Energy Corporation's Annual
Report on Form 10-K for the year ended December 31, 1994 present fairly, in  all
material  respects, the financial  position of Wisconsin  Energy Corporation and
its subsidiaries  at  December 31,  1994  and 1993,  and  the results  of  their
operations  and their cash flows for each of the three years in the period ended
December 31, 1994, in conformity with generally accepted accounting  principles.
These  financial statements are the  responsibility of the Company's management;
our responsibility is to express an opinion on these financial statements  based
on  our  audits.  We  conducted  our audits  of  these  financial  statements in
accordance with generally accepted auditing standards which require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on  a
test  basis, evidence  supporting the amounts  and disclosures  in the financial
statements, assessing the accounting  principles used and significant  estimates
made by management, and evaluating the overall financial statement presentation.
We  believe that our audits provide a reasonable basis for the opinion expressed
above.

                          INDEPENDENT AUDITORS' REPORT

To The Shareholders of Northern States Power Company:

    We  have audited  the consolidated  financial statements  of Northern States
Power Company (Minnesota) and its subsidiaries, listed in the table of  contents
in Item 14(a)1 of Northern States Power Company's Annual Report on Form 10-K for
the  year ended December  31, 1994. These  consolidated financial statements and
financial  statement  schedules  are   the  responsibility  of  the   Companies'
managment.  Our  responsibility is  to express  an  opinion on  the consolidated
financial statements and financial statement schedules based on our audits.

    We conducted  our  audits in  accordance  with generally  accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance  about whether  the consolidated  financial statements  are
free  of material  misstatement. An audit  includes examining, on  a test basis,
evidence supporting the amounts and disclosures in the financial statements.  An
audit  also includes  assessing the  accounting principles  used and significant
estimates made by  management, as  well as evaluating  the overall  consolidated
financial   statement  presentation.  We  believe  that  our  audits  provide  a
reasonable basis for our opinion.

    In our opinion,  such consolidated financial  statements present fairly,  in
all  material respects, the financial position  of the Companies at December 31,
1994 and 1993 and the results of their operations and their cash flows for  each
of  the three  years in the  period ended  December 31, 1994  in conformity with
generally accepted accounting principles.

    As discussed  in  Note  3  to the  consolidated  financial  statements,  the
Companies  changed  their method  of accounting  for postretirement  health care
costs in 1993.

LETTER FROM THE CHAIRMEN

Northern States Power Company and Wisconsin Energy Corporation are combining to
form Primergy Corporation. Through this combination, we are seeking to benefit
shareholders of both companies by creating a more competitive company in our
changing business environment. We expect this "merger of equals" to create
opportunities for earnings and dividend growth for our combined shareholders. At
our upcoming shareholders' meetings on September 13, 1995, we encourage you to
vote in favor of the merger.

Our recognition of the inevitable changes and consolidation coming to the energy
industry prompted our agreement in April 1995 to merge our two companies. The
merger will increase our financial strength and flexibility to help us remain
successful in this increasingly competitive environment. Primergy will be the
tenth largest investor-owned utility company in the United States, based on
historical market capitalization.

Primergy is expected to have many and significant advantages, including greater
efficiencies and estimated cost savings of about $2 billion over the next 10
years. These savings will help us ensure continued competitive rates over the
long term, which will enable our communities to attract new business, add jobs
and strengthen the economy in our combined service area.

Our commitment to the area we serve extends beyond strengthening its economy.
Primergy's operating companies will remain active supporters of our
neighborhoods and communities; our strong commitment and presence will continue.

With this merger, we are initiating a thoughtful combining of resources and
talents to manage successfully in the more demanding times ahead. The merger
brings together the experience of NSP and WEC in both regulated and unregulated
markets. Together, we should be in an excellent position to provide superior
service to our customers at attractive prices. Our common goal is to be a
premier investor-owned energy company -- in meeting customer needs, offering
competitive rates and creating shareholder value.

Recently, we filed our joint merger application with the Federal Energy
Regulatory Commission, and we expect to file soon with other federal and state
regulatory bodies where merger approval is required. In addition, on September
13, 1995, we will hold meetings in Milwaukee and Minneapolis for shareholders of
both companies to vote on the proposed merger, as discussed in the enclosed
joint proxy materials. We expect that, pending receipt of all regulatory
approvals needed, the transaction will be completed by the fourth quarter of
1996.

Inside, and in the accompanying joint proxy materials, you will read more about
the strategic reasons that led to this proposed merger and the significant
benefits it can provide to our shareholders. The realization of these benefits
is dependent on, among other things, your approval of the transaction and on
receipt of satisfactory regulatory approvals. While we believe that the merger
will create numerous opportunities for enhancing shareholder value, there can be
no guarantee that the anticipated benefits will be achieved. We encourage you to
read the information carefully and to vote in favor of the merger at the
September 13 shareholders' meetings. Together, we're even better.

MERGER BENEFITS

            We believe that the merger of Northern States Power
            Company and Wisconsin Energy Corporation will create a
            stronger company with key strategic advantages in a
            competitive market for energy, including low-cost energy
            and a more diverse service area.

            Shareholders will be participants in a larger company
            with greater financial flexibility, strength and
            improved cash flow. The transaction is designed to be
            tax-free to shareholders of both companies. We believe
            the merger will create numerous opportunities for
            enhancing shareholder value, including:

            - Providing opportunities for continued increases in
              earnings and dividends for shareholders at a level
              greater than they would have been without the creation
              of Primergy.

            - Achieving cost savings that will enable NSP and WEC's
              utility subsidiary to propose a reduction in retail
              electric rates of 1.5 percent in 1997, followed by a
              rate freeze through the year 2000.

            - Improving our ability to thrive in a more competitive
              environment.

            subsidiaries of Primergy Corporation]

COST SAVINGS

We estimate the Primergy merger will create savings, net of costs to achieve, of
about $2 billion over the next 10 years. Savings are expected to result
primarily from:

- Labor cost reductions achieved by eliminating duplicate functions within
  corporate and operations areas.

- Combining corporate and administrative programs.

- Purchasing economies in fuel and natural gas procurement.

- Streamlining nuclear and other operations.

The regulatory process will determine the allocation of these benefits between
customers and shareholders. Primergy will seek regulatory treatment that will
allow an equitable level of benefits to flow to shareholders.

ENHANCED ECONOMIC DEVELOPMENT AND COMMUNITY INVOLVEMENT

Lower energy prices resulting from the merger should make the combined service
area more attractive to business and stimulate economic growth in the region.
Further, the merger should foster:

- Continued commitment to the community through the resources of Primergy and
  its subsidiaries in philanthropic and volunteer programs.

- Strong community partnerships in economic development activities.

PRIMERGY: STRUCTURE

Primergy will be a registered public utility holding company. After the merger,
Northern States Power Company and Wisconsin Energy Company-a consolidation of
Wisconsin Energy's existing utility subsidiaries (Wisconsin Electric Power
Company and Wisconsin Natural Gas Company)--will continue to operate under those
names as the principal subsidiaries of Primergy. NRG Energy, Inc. (a
non-regulated subsidiary with interests in independent, non-regulated power and
energy businesses in the United States and other countries) and other non-
regulated businesses of NSP and WEC also will be subsidiaries of Primergy.

HEADQUARTERS

Primergy will be a Wisconsin corporation with its headquarters in Minneapolis.
The two operating utilities will maintain their current headquarters, Northern
States Power Company in Minneapolis and Wisconsin Energy Company in Milwaukee.

MANAGEMENT

The transaction documents contemplate that, following completion of the merger,
James J. Howard will serve as chairman and chief executive officer of Primergy,
and Richard A. Abdoo will become vice chairman, president and chief operating
officer of Primergy. Abdoo will become chief executive officer of Primergy on or
about May 1998. Howard will continue as chairman of Primergy until his expected
normal retirement date in July 2000. Abdoo will become chairman of Primergy upon
Howard's retirement.

ANSWERS TO CERTAIN QUESTIONS YOU MAY HAVE

How many shares of Primergy common stock will I receive for every share of NSP
common stock I own?

NSP shareholders will receive 1.626 shares of Primergy common stock in exchange
for every one share of NSP common stock they own. For example, if you own 1,000
shares of NSP common stock, you will receive 1,626 shares of Primergy common
stock.

How many shares of Primergy common stock will I receive for every share of WEC
common stock I own?

Each share of WEC common stock will remain outstanding as one share of Primergy
common stock. For example, if you own 1,000 shares of WEC common stock, you will
own 1,000 shares of Primergy common stock.

How was the exchange ratio derived?

The transaction is a true "merger of equals." NSP and WEC have roughly the same
market capitalization, and bring equal value to Primergy. Accordingly, the
exchange rate was calculated to ensure that NSP's shareholders as a group and
WEC's shareholders as a group (based on shares outstanding on April 20, 1995)
each received 50 percent of the equity in Primergy.

Will I receive a new stock certificate in the exchange?

If you hold a certificate representing NSP common stock, it will be exchanged
for a Primergy certificate. You will receive further information on how to make
the exchange after the merger is final, and you should continue to hold your NSP
certificate until notified. WEC certificates and certificates representing NSP
preferred stock do not have to be exchanged and will remain valid following the
merger.

If you hold either NSP or WEC shares in a stock plan or place your current
certificates into a stock plan, your shares will be automatically converted
without the issuance of a new certificate.

What about fractional shares of stock?

Fractional shares of Primergy common stock that result from the exchange of NSP
common stock will be paid in cash and will need to be reported on your tax
filings. If you choose to place your NSP common shares in NSP's Dividend
Reinvestment and Stock Purchase Plan, or if you currently hold shares in that
Plan, such shares so held at the time of the merger will be fully converted into
full and fractional shares of Primergy common stock, eliminating the tax filing
requirements associated with the receipt of cash for a fractional share.

What happens to the preferred stock?

The holders of preferred stock of NSP (which for regulatory reasons will
reincorporate in Wisconsin) will receive in exchange the same number of shares
of preferred stock in the successor Wisconsin corporation with identical terms.
The preferred stock of Wisconsin Electric Power Company, WEC's utility
subsidiary, will remain outstanding after the transaction.

Will I be taxed on the exchange of stock?

No. It is a condition of the transaction that the parties receive opinions of
their tax counsel, based upon a ruling from the Internal Revenue Service, that
for federal income tax purposes the exchange of stock (other than cash paid in
lieu of fractional shares) will qualify as a tax-free transaction.

Please note that shareholders of NSP preferred and common stock have the right
to dissent to the merger, as explained more fully in the enclosed proxy
materials. NSP shareholders who do so will be subject to tax on any gains that
are realized.

Will the merger affect the current dividend policy of NSP or WEC?

Both companies expect to continue with their current dividend policies until the
merger is completed. We anticipate that Primergy will adopt NSP's dividend
payment level adjusted for the exchange ratio. NSP currently pays $2.70 per
share

                                       6
<PAGE>
annually, and WEC's annual dividend rate is currently $1.47 per share. Based on
the exchange ratio and NSP's current dividend rate, the pro forma dividend rate
for Primergy as of today would be $1.66 per share. Both companies have
historically increased their dividends consistently and anticipate that such
policies will continue, both before and after the merger, subject to board
action based on such factors as earnings performance, financial condition,
capital requirements and regulatory constraints.

Did independent financial advisors review the exchange ratio?

Yes. Financial advisors were retained by both companies. The advisors, Goldman,
Sachs & Co. for NSP and Barr Devlin & Co. Incorporated for WEC, each rendered an
opinion as to the fairness of the exchange ratio to shareholders. Additional
information is included in the proxy materials enclosed.

How will Primergy's board be structured?

The board initially will be composed of 12 directors, half from NSP and half
from WEC.

Will gas utility and non-utility operations be sold?

Divestiture of the gas utility and certain non-utility operations of the two
companies might be required under the registered holding company structure.
However, we will seek approval from the Securities and Exchange Commission to
retain these businesses. If divestiture ultimately is required, the Securities
and Exchange Commission historically has allowed companies sufficient time to
accomplish it in a manner that protects shareholder value.

How long will it take to complete the merger?

We anticipate the transaction can be completed by the fourth quarter of 1996,
subject to receipt of all required approvals.

Apart from shareholder votes, what approvals are necessary to complete the
merger?

We recently filed for Federal Energy Regulatory Commission approval. The merger
also requires approval of various other agencies, including the Securities and
Exchange Commission, the Nuclear Regulatory Commission, the Federal Trade
Commission and state regulators in Minnesota, Wisconsin and other states where
the companies conduct business.

What effect will the merger have on local control?

Local control will be maintained. After the merger, headquarters of the two
principal operating subsidiaries, Northern States Power Company and Wisconsin
Energy Company, will remain in their current locations in Minneapolis and
Milwaukee. The companies will continue to pay taxes to the states and localities
they serve and to work with their local regulatory bodies.

When the transaction is complete, we expect that NSP-Wisconsin will merge into
Wisconsin Energy Company, and its office in Eau Claire, Wisconsin, would no
longer need to operate as a corporate headquarters office. Primergy will
continue, however, to provide strong community support and to work with
communities to keep western Wisconsin healthy and vital.
