Item 1.  Description of Proposed Transaction

A.       Introduction

                 This  Application/Declaration  seeks approvals  relating to the
proposed combination of WPL Holdings, Inc. ("WPLH"), IES Industries Inc. ("IES")
and Interstate Power Company ("IPC"), pursuant to which IES' utility subsidiary,
IES Utilities Inc. ("Utilities"),  and IPC will become subsidiaries of WPLH (the
"Transaction").  WPLH will be renamed Interstate Energy Corporation ("Interstate
Energy")  at  or  prior  to  such  time.   Following  the  consummation  of  the
Transaction,  Interstate  Energy will register with the  Securities and Exchange
Commission  (the  "Commission")  as a holding  company under the Public  Utility
Holding Company Act of 1935 (the "Act").

                 WPLH,  IES  and  IPC  believe  that  their  combination  offers
significant  strategic  and  financial  benefits  to each  company  and to their
respective  shareowners,  as well as to their  employees  and  customers.  These
benefits include,  among others:  (i) maintenance of competitive rates that will
improve the combined entity's ability to meet the challenges of the increasingly
competitive  environment in the utility  industry,  (ii) reduced operating costs
and  expenditures  resulting from  integration  of corporate and  administrative
functions,   including  the  elimination  of  duplicative  positions,   limiting
duplicative  capital   expenditures  for  administrative  and  customer  service
programs and information  systems, and savings in areas such as legal, audit and
consulting  fees,  (iii)  reduced  electric  production  costs through the joint
dispatch of systems and natural gas supply savings through combined  purchasing,
(iv)  greater  purchasing  power  for  items  such  as fuel  and  transportation
services,  general and  operational  goods and  services  and the  reduction  of
inventories,  (v) more controlled  expansion into non-core  utility  businesses,
(vi)  increased   customer   diversity  and  geographic   diversity  of  service
territories,  reducing  exposure to local  changes in economic,  competitive  or
climatic  conditions,  and (vii)  expanded  management  resources and ability to
select  leadership from a larger and more diverse  management pool. In addition,
WPLH,  IES and IPC  believe  that  synergies  created  by the  Transaction  will
generate  substantial  cost  savings to  Interstate  Energy  which  would not be
available to the separate  companies absent the  Transaction.  WPLH, IES and IPC
have  estimated  the  dollar  value  of  certain  synergies  resulting  from the
Transaction to be  approximately  $749 million on a nominal dollar basis, net of
costs to achieve the  savings,  over the 10-year  period from 1997 to 2006.  The
expected Transaction benefits are discussed in further detail in Item 3.A.2.b.i.
below. Despite the passage of time since the original estimate of synergies,
WPLH, IES and IPC are still confident that such savings can be realized over
the period.
                 The Transaction was approved by the shareholders of WPLH and
IPC at their respective  meetings  held on  September  5,  1996,  and based on
preliminary tabulations,  was approved by the shareholders of IES at its meeting
held on September 5, 1996.  WPLH,  IES and IPC submitted applications
requesting approval of the Transaction and/or related matters to (i) the Public
Service Commission of Wisconsin (the  "PSCW"),  (ii) the Iowa Utilities  Board
(the "IUB"),  (iii) the Minnesota  Public  Utilities Commission (the "MPUC"),
(v) the Illinois Commerce  Commission   ("ICC"), (vi) the  Federal  Energy
Regulatory Commission (the "FERC") and (vii) the Nuclear Regulatory Commission
(the "NRC") and received orders authorizing the companies to proceed with the
transaction. The Orders of the PSCW, IUB, MPUC and FERC were filed as Exhibits
O-4, O-5, O-6 and N-3, respectively. Finally, the three companies have made the
required filings with the Antitrust Division of the U.S. Department of Justice
(the "DOJ") and the Federal  Trade  Commission  (the "FTC") under the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR
Act"). See Item 4 below for additional  detail  regarding these  regulatory
approvals. Apart from the approval of the  Commission  under the Act, the
foregoing approvals   are  the  only   regulatory   approvals required  for the
Transaction.  In order to permit timely  consummation of the Transaction and the
realization  of the  substantial  benefits  it is  expected to produce, the
applicants  request that the  Commission's  review of this
Application/Declaration   commence  and  proceed  as   expeditiously  as
practicable.

         1.      General Request

                 Pursuant to Sections  9(a)(2) and 10 of the Act, the applicants
hereby request authorization and approval of the Commission for WPLH to acquire,
by means of the direct mergers or the  reincorporation  mergers described below,
all of the  issued  and  outstanding  common  stock  of IPC and  Utilities.  The
applicants  also hereby request that the Commission  approve (i) the transfer of
certain of  Interstate  Energy's  non-utility   interests  to  a  subsidiary  of
Interstate Energy ("Interstate Hold") which will be formed prior to consummation
of the  Transaction  to serve as a  holding  company  for  substantially  all of
Interstate Energy's  non-utility  subsidiaries under Section 9(a)(1) of the Act;
(ii) the establishment of Interstate Services, Inc. ("Interstate Services") as a
subsidiary   service  company  of  Interstate  Energy  in  accordance  with  the
provisions  of  Rule  88 of  the  Act;  (iii)  the  Service  Agreement  and  the
Non-Utility Service Agreement (described in Item 1.B.1.a.iii.  below) as a basis
for  Interstate  Services  to  comply  with  Section  13  of  the  Act  and  the
Commission's  rules  thereunder;  (iv) the retention by Interstate Energy of the
gas  properties  of its  utility  subsidiaries  and  the  continuation  of  such
subsidiaries  as combination  gas and electric  utilities;  (v) the retention by
Interstate Energy of the non-utility  businesses of WPLH, IES and IPC and of the
non-utility  affiliates of WPLH, IES and IPC; (vi) all outstanding  intra-system
obligations  and guarantees;  (vii) the issuance of shares of Interstate  Energy
Common  Stock,  $.01 per  share,  (the  "Interstate  Energy  Common  Stock")  in
connection with the Transaction;  (viii) authority, through a period ending five
years after the date of the Commission's  Order approving the matters  requested
hereby,   for  Interstate   Energy  to  issue  (and/or  acquire  in  open-market
transactions)  up to 11 million  shares of Interstate  Energy Common Stock under
dividend reinvestment and stock-based  management incentive and employee benefit
plans;  (ix) the  issuance of rights to  purchase  shares of  Interstate  Energy
Common  Stock  pursuant to the terms of the Rights  Agreement  between  WPLH and
Morgan Shareholder Services Trust Company, as Rights Agent thereunder,  dated as
of  February  22,  1989  (the  "Rights  Agreement"),  the sale and  issuance  of
Interstate  Energy  Common Stock upon  exercise of the Rights and certain  other
transactions contemplated by the Rights Agreement; and (x) exemption from the at
cost standards of certain transactions.

         2.      Overview of the Transaction

                 Pursuant  to an  Agreement  and  Plan  of  Merger  dated  as of
November  10, 1995,  as amended  (together  with a related  Plan of Merger,  the
"Merger  Agreement"), (i) IES will be merged with and into WPLH, with WPLH
as the surviving corporation (the "IES Merger"),  and (ii) WPLH Acquisition Co.,
a wholly-owned  subsidiary of WPLH  incorporated  under the laws of the State of
Wisconsin  ("Acquisition"),  will be merged  with and into IPC (the "IPC  Direct
Merger"),





                                       2
<PAGE>   7

which will result in IPC becoming a subsidiary of WPLH.  Immediately prior to or
upon consummation of the transactions  described in the Merger  Agreement,  WPLH
will be renamed Interstate Energy Corporation. The alternative structure for
consummating the mergers as contemplated by the Merger Agreement will not be
utilized by the parties because the PSCW issued a final order determining that
the reincorporation mergers provided for in such alternative structure were not
required.

                 As a  result of  the IES  Merger  and  the IPC  Direct  Merger,
Utilities and IPC will  become operating  utility  subsidiaries  of  Interstate
Energy,  and WPLH's existing  operating  utility  subsidiary,  Wisconsin Power &
Light  Company  ("WP&L"),   will  remain  a  subsidiary  of  Interstate  Energy.
Accordingly,  upon  consummation of the Transaction,  Interstate Energy will own
three combination electric and gas public utility companies.

                 Upon consummation of the Transaction,  Interstate Services will
become a  wholly-owned  service  company  subsidiary  of  Interstate  Energy and
subsequent to the  consummation of the Transaction the non-utility  subsidiaries
of WPLH and IES will become subsidiaries of Interstate Hold, which will serve as
a holding company for substantially all of the non-utility  subsidiaries of, and
will be  wholly-owned  by,  Interstate  Energy.  Applicants are also  requesting
approval of the terms of (1) the Service Agreement among Interstate Services and
the operating utility  subsidiaries of Interstate Energy and (2) the Non-Utility
Service Agreement between





                                       3
<PAGE>   8

Interstate  Services and the non-utility  subsidiaries of Interstate  Energy.  A
chart  of the  proposed  corporate  structure  of  Interstate  Energy  following
consummation of the Transaction is attached hereto as Exhibit A.

                 The common  shareholders  of IES and IPC will receive shares of
Interstate  Energy  Common  Stock in  exchange  for their  shares of IES and IPC
Common Stock (as defined  below),  respectively,  and, thus,  will become common
shareholders  of  Interstate  Energy.  The  exchange  ratios  applicable  to the
conversion of IES and IPC common stock into  Interstate  Energy Common Stock are
described  in  Item  1.C.2.  below. The Transaction   will  have  no effect on
the shares of cumulative preferred stock, $50  par  value,  of   Utilities
("Utilities   Preferred  Stock") or the shares of  preferred  stock, $50 par
value, of  IPC ("IPC Preferred Stock") issued and outstanding at the  time of
the  consummation of the Transaction, each series of which and each share of
which  will  remain unchanged (other than IPC Dissenting Shares). A copy of the
Merger  Agreement is incorporated by reference as Exhibit B hereto.

          
                 A. Antitrust.  The  Applicants fully satisfied the requirements
under  the  HSR  Act  on July 7, 1996. However,  because  the Applicants did not
consummate  the  Transaction within one year of that date, the   Applicants were
obliged to re-notify the DOJ and FTC of the proposed Transaction. The Applicants
resubmitted  the necessary  filings  under the HSR Act on September 3, 1997. The
HSR  Act  imposes  a  30-day  waiting period for the consummation of each merger
comprising the Transaction subject to the HSR Act's prenotification requirement.
The Applicants, however, requested and were granted early termination of that
waiting period by the FTC on September 12, 1997.


                 B. Federal Power Act. The Administrative Law Judge presiding
over the FERC proceeding issued his Initial Decision on Rate and Merger Issues
in Docket Nos EC96-13-000, ER96-1236-000 and ER96-2560-000 approving the
Transaction, subject to conditions, on July 3, 1997. The Initial FERC Decision
was subject to FERC review; the subsequent FERC order, Opinion No. 419,
approving the transaction, was issued on November 12, 1997.


                 C. Atomic Energy Act. The NRC approved the Transaction relative
to the Duane Arnold Energy Center on August 28, 1997. Pursuant to the Order,
parties had until October 6, 1997 to request a hearing on the Order; no such
hearing was requested.

                 D. State Public Utility Regulation. The MPUC approved the
Transaction in Minnesota Public Utilities Commission Opinion and Order at Docket
No. E, 6-100/PA-96-184 (March 24, 1997). The ICC approved the Transaction in
Illinois Commerce Commission Opinion and Order in Matter No. 96-1022 (May 7,
1997) (filed as Exhibits 0-3- (a) and 0-4-(a)). The IUB approved the Transaction
at Docket No. SPU-96-6 on September 16, 1997 (filed as Exhibit 0-5-(a)). The
PSCW, in an Order relating to Docket No. 6680-UM 100, as effective November 6,
1997, approved the merger subject to conditions (filed as Exhibit 0-6-(a)).

                 Pursuant to the Applicant's agreement with the PSCW and in
response to the PSCW Order effective November 6, 1997, the Applicants hereby
request that the Commission include in any order approving IEC as a registered
holding company:

               Approval of the Application in no way precludes the Public
               Service Commission of Wisconsin, the Iowa Utilities Board, the
               Minnesota Utility Commission, the Illinois Commerce Commission
               or any other state regulatory authority from scrutinizing and
               disallowing the pass through of costs and rates for services
               rendered to customers of the client companies. It is the SEC's
               intention that each state commission having jurisdiction over a
               client company will retain the right to review and disallow
               costs of services provided to a client company by Interstate
               Services, Inc., that may be subject to recovery in rates.
        


B.       Description of the Parties to the Transaction

         1.      General Description

                 a.       WPLH (to be renamed Interstate Energy Corporation) and
         its Subsidiaries

                          i.      WPLH

                 WPLH was incorporated  under the laws of the State of Wisconsin
in 1981 and is a public utility holding company exempt from regulation under the
Act (except for Section 9(a)(2) thereof)  pursuant to Section 3(a)(1) of the Act
and by order of the  Commission  in WPL  Holdings,  Holding  Co. Act Release No.
24590  (February 26,  1988),  as reaffirmed in Holding Co. Act Release No. 25377
(September 18, 1991).  As stated above,  WPLH will change its name to Interstate
Energy Corporation at or prior to consummation of the Transaction.

                 WPLH owns all of the issued  and  outstanding  common  stock of
WP&L,  and WP&L owns all of the issued  and  outstanding  common  stock of South
Beloit  Water,  Gas  and  Electric  Company,  an  Illinois  corporation  ("South
Beloit"). South Beloit has been a wholly-owned subsidiary of WP&L since prior to
1930. WP&L also owns 33 1/3% of Wisconsin River Power Company ("WRPC"), a public
utility which owns and operates two  hydro-electric  facilities on the Wisconsin
River. WP&L, incorporated under the laws of the State of Wisconsin





                                       4
<PAGE>   9

on February 21, 1917, is a public utility holding company exempt from regulation
by the Commission under the Act (except for Section 9(a)(2) thereof) pursuant to
Section  3(a)(2)  of the Act and Rule 2  thereunder.  WP&L and South  Beloit are
combination  electric and gas public  utility  companies  under the Act. WP&L is
engaged principally in generating, purchasing, distributing and selling electric
energy in 35 counties in southern  and  central  Wisconsin.  As of December  31,
1995, WP&L furnished retail electric service to approximately  370,000 customers
in 663  cities,  villages  and towns,  and  wholesale  service  to 27  municipal
utilities,  one privately-owned  utility,  three rural electric cooperatives and
the Wisconsin Public Power Incorporated  SYSTEM ("WPPI"),  which provides retail
service to nine communities. WP&L also purchases,  distributes and sells natural
gas to retail  customers  in 22 counties in southern and central  Wisconsin;  it
also  supplies  water to customers in two Wisconsin  communities,  including the
cities of Ripon and Beloit and areas adjacent thereto.  As of December 31, 1995,
WP&L provided natural gas to approximately 141,000 customers and water to 31,620
customers.  South Beloit  supplies  retail  electric,  gas and water  service to
customers in South Beloit and Rockton,  Illinois and the rural areas adjacent to
such cities.  As of December 31, 1995,  South Beloit provided  electric  utility
service to 7,005 customers,  gas utility service to 5,128  customers,  and water
service to 1,598 customers.  The service territory of South Beloit is located in
Illinois and is adjacent to the territory served by WP&L in Wisconsin.  A map of
the combined  service  territory of WP&L and South Beloit is attached as Exhibit
C-1.

                 WP&L is subject to regulation as a public  utility as to retail
electric,   gas  and  water  rates,  service  rules,   issuance  of  securities,
construction of new facilities,  transactions  with affiliates and various other
matters by the PSCW.  South Beloit is subject to regulation as a public  utility
as to retail electric, gas and water rates, accounts, issuance of securities and
other  matters by the ICC.  WP&L and South Beloit are also subject to regulation
by the FERC  with  respect  to the  classification  of  accounts,  rates for any
wholesale sales of electricity,  wheeling rates for the interstate  transmission
of  electric  power  and  energy,   interconnection  agreements,   issuances  of
securities  not regulated by state  commissions  and  acquisitions  and sales of
certain utility  properties  under the Federal Power Act. WP&L is also currently
subject to regulation by the NRC in  connection  with its ownership  interest in
the Kewaunee Nuclear Plant.

                 Exhibit M-5 describes the non-utility businesses of WPLH  which
are  held by  its  subsidiary  Heartland  Development  Corporation, a  Wisconsin
corporation  ("HDC").  For the year ended December 31, 1995,  approximately  15%
of  WPLH's  consolidated  operating  revenues were derived from its  non-utility
investments.  As of December 31, 1995, less than  13.34% of  WPLH's consolidated
assets were invested in non-utility businesses.

                 WPLH, as a public utility holding company (a "holding company")
under  the  Wisconsin  Holding  Company  Act  (the  "Wisconsin  Act"),  is (and,
following consummation of





                                       5
<PAGE>   10

the  Transaction,  Interstate  Energy  will  continue  to  be)  subject  to  the
jurisdiction  of, and  regulation by, the PSCW. The following is a brief summary
of certain provisions of the Wisconsin Act that currently apply to WPLH and will
apply to Interstate Energy.

                 The PSCW may  order  the  utility  affiliate  to limit or cease
payment of  dividends  to the  holding  company  if it finds the  capital of any
public utility  affiliate of a holding  company will be impaired by payment of a
dividend.  Various transactions by a public utility affiliate with others in the
holding company system are prohibited,  including:  lending money,  guaranteeing
obligations, combining advertising, providing utility service on terms different
from  those for other  consumers  in the same  class,  and,  selling  or leasing
certain  real  property  and using  the  services  of  utility  employees  after
establishing  that the  utility  affiliate  will be paid at fair  market  value,
unless the PSCW  approves the  transaction.  The Wisconsin 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 any public utility affiliate's  credit,  ability to
acquire  capital on  reasonable  terms or ability to provide  safe,  reasonable,
reliable and adequate  utility  service,  (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
PSCW has approved the transfer and (v) any termination of the system's  interest
in a public utility affiliate without PSCW approval.

                 The Wisconsin Act also limits non-utility diversification.  The
Wisconsin  Act  generally  provides that 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 PSCW (but not less than 25%), of the
net book value of all other public utility  affiliates  (the PSCW has fixed that
percentage  at 25%  for  book  value of WP&L's gas utility  business).  Further,
the Wisconsin Act requires the PSCW  periodically  to 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  other   businesses,  (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
providing utility service or to developing or acquiring energy resources  or (d)
develop or operate commercial or industrial parks  in  the service  territory of
any  public utility  affiliate.  The PSCW is also authorized to order a  holding
company to terminate its interest in a public  utility affiliate if the





                                       6
<PAGE>   11

PSCW finds that,  based upon clear and convincing  evidence,  termination of the
interest  is  necessary  to protect  the  interests  of utility  investors  in a
financially  healthy  utility  and the  interests  of  consumers  in  reasonably
adequate utility service at a just and reasonable price.

                 The common  stock,  par value $.01 per  share,  of WPLH  ("WPLH
Common  Stock") is listed on the New York Stock  Exchange  ("NYSE"),  the Boston
Stock Exchange ("BSE"), the Chicago Stock Exchange ("CSE") and the Pacific Stock
Exchange  ("PSE").  As of July 10, 1996,  there were  30,795,260  shares of WPLH

345 kV Line").  WP&L and South  Beloit are  directly  interconnected  by a 69 kV
transmission line. WP&L is a member of the Mid-America  Interconnected  Network,
Inc. ("MAIN"), an interstate network of transmission  facilities which are owned
by  public  entities  and  investor-owned   utilities.   MAIN  is  the  regional
reliability  council  providing  planning and  coordination  for member electric
power systems in the  North-Central  United States.  However,  WP&L has notified
MAIN that it intends to withdraw from MAIN effective  December 31, 1997. WP&L is
also an  associate  member,  and  Utilities  and IPC are  full  members,  of the
Mid-America Power Pool ("MAPP") which is an economic power pool that operates an
electronic   bulletin  board  and  acts  as  a  clearinghouse   for  bulk  power
transactions among over 28 member utilities and marketers.  WP&L,  Utilities and
IPC  intend  to  operate  Interstate  Energy  as a single  system,  economically
dispatched pursuant to the Coordination Agreement.

                 WP&L,  Utilities and IPC are also each directly  interconnected
to   numerous   other   neighboring   utilities.   In  addition  to  its  direct

with nine neighboring  utilities:  CIPCO,  Corn Belt,  MAEC,  Western Area Power
Authority,  Muscatine  Power and Water,  Associated  Electric  Cooperative,  UE,
Central  Illinois  Public  Service and  Northeast  Missouri  Power  Cooperative.
Utilities is also a party to a coordination  agreement with CIPCO which provides
for the joint  dispatch of the  Utilities and CIPCO  resources  and  coordinated
operation of a portion of Utilities'  transmission system with the facilities of
CIPCO.  WP&L and South Beloit are directly  interconnected  with six neighboring
utilities:  ComEd, DPC, Madison Gas & Electric Company,  NSP, Wisconsin Electric
Power  Company  and  Wisconsin   Public  Service   Corporation.   Through  these
interconnections  with neighboring utilities and others, WP&L, Utilities and IPC
can wheel electric energy throughout the combined Interstate Energy system.
                 WP&L and IPC also plan to  construct  two direct
interconnections  between  their  systems  across the Mississippi  River
following  consummation  of  the  Transaction, when authorized by the FERC to do
so, including a 69 kV tie-line  between  Prairie du Chien,  Wisconsin and
MacGregor, Iowa and a 161 kV line connecting  WP&L's Nelson Dewey  generating
plant on the east side of the river to IPC's Turkey River substation on the west
side.

                  IEC will be an integrated electric system within the meaning
of Section 2(a)(29)(A) of the Act. IEC will be operated as a single system,
economically dispatched pursuant to the Coordination Agreement. Utilities and
IPC ("IEC West") are presently directly interconnected(1) and WP&L and South
Beloit ("IEC East") are presently directly interconnected.(2) IEC West and IEC
East are presently interconnected through firm contractual wheeling arrangements
with third parties(3) and through MAPP.(4) Additionally, IEC intends to build
two tie-lines (aggregating 250 MW of transfer capability) between IEC West and
IEC East.(5) In the Federal Energy Regulatory Commission Initial Decision on
Rate and Merger Issues (Issued July 3, 1997) (the "Initial FERC Decision"), the
Administrative Law Judge, however, ordered the Applicants to delay construction
of the tie-lines between IEC West and IEC East until the Applicants have 
constructed 400 MW of additional simultaneous import capability into the
Wisconsin Upper Michigan System ("WUMS"). IES Utilities et al, 80 F.E.R.C.
Paragraph 63,001, 21 (1997).

                  On November 12, 1997, the Federal Energy Regulatory Commission
(the "FERC") issued its decision on the merger. IES Utilities, Inc. et al.,
Opinion No. 419, 81 FERC Paragraph 61, ___ (1997) ("Opinion No. 419"). In
Opinion No. 419, the FERC accepted a competition stipulation that had been
negotiated by the Applicants and the FERC trial staff, as modified to include an
extra condition imposed by the presiding Administrative Law Judge. The
competitive stipulation, as modified, generally addresses the Applicants' use of
firm transmission service purchased from ComEd and DPC in order to achieve joint
dispatch; Applicants' proposal to construct two additional transmission lines
between IEC West and IEC East at a future time; Applicants' proposal to make
eight specified transmission improvements to increase transfer capability into
WUMS; Applicants' obligation to purchase additional point-to-point transmission
service if joint dispatch transfers between IEC West and IEC East exceed the
contract path quantity; and alternative dispute resolution and additional
efforts to increase transfer capability into WUMS if the specified measures are
not fully successful.

                  The record developed in the FERC proceeding demonstrates that,
at present, although IEC West and IEC East are interconnected through
neighboring utilities, there are no high voltage connections directly between
Iowa and WUMS. Initial FERC Decision at 30. Additionally, the transmission
capability between Iowa and WUMS is limited. In short, power cannot go straight
from Iowa to WUMS but must flow across the grid which is already constrained. As
a result of physics, due to the nature of the way power flows across the grid
and the engineering peculiarities of the Iowa-WUMS interface, the joint dispatch
of the Applicants' generating facilities through use of their 200 MW of
transmission rights(6) will result in the Applicants' using up much of the
import capability into WUMS thereby during times of system constraint preventing
competitors of the Applicants from selling power into WUMS.

                  The immediate construction of the tie-lines(7) will, for
reasons of physics and engineering peculiar to the Iowa-WUMS interface, not
alleviate the congestion at the constrained interface. Accordingly, the Initial
Decision and Opinion No. 419 direct the Applicants to delay construction of
their new tie-lines until the Applicants construct additional facilities to
increase the overall transfer capability into WUMS. The construction of these
additional facilities will reinforce the electrical interconnection between Iowa
and WUMS. The requirements of the competitive stipulation adopted by Opinion No.
419 are only necessary because, as a factual, physics and engineering matter,
the Applicants are currently interconnected and capable of integrated operation
to the point where they must first provide transmission capacity for others
before construction of the tie-lines.

                  The type and degree of physical interconnection described in
the Initial FERC Decision is sufficient to establish interconnection under the
Act for the purposes of Sections 2(a)(29)(A), 10(c)(2) and 11(b)(1). The
Commission has found that proposals to contract for or to construct physical
connections between utilities in a single system satisfy the interconnection
requirement. See New England Electric System, 38 S.E.C. 193, 198-99 (1958)
(engineering studies and testimony showing feasibility of direct
interconnections among four small systems satisfied the requirements of the Act
that utilities be "capable of physical interconnection"); Mississippi Valley
Generating Co., 36 S.E.C. 159 (1955) (while complete direct physical
interconnection between the companies involved did not currently
exist, the Commission recognized that physical interconnection was possible
through the construction of transmission lines).

               Additionally, the Commission has found that two utilities that
are capable of sharing power through wheeling or power pool arrangements (as the
Applicants will be forced to do upon consummation of the Transaction pending
further construction of new transmission facilities) are physically
interconnected or capable of physical interconnection. The fact that two
facilities may be separated by other facilities that are not owned by the
holding company does not change the fact that they are interconnected or capable
of physical connection and of supplying power to one another as needed. City of
New Orleans v. SEC, 969 F.2d 1163, 1165 (D.C. Cir. 1992).

               The Commission has also acknowledged that utilities can be
interconnected through power pools or by means of contractual rights to use the
lines of a third party. See Northeast Utilities, Holding Co. Act Release No.
25273 (Mar. 15, 1991); Centerior Energy Corp., Holding Co. Act Release No. 24073
(April 29, 1986); UNITIL Corp., Holding Co. Act Release No. 25524 (Apr. 24,
1992). The Commission has recognized that a finding that wheeling and other
forms of sharing power through reliability councils and proposed regional
transmission groups also qualify as "interconnection" under section 2(a)(29)(A)
of the Act appears to be a logical extension of prior Commission holdings. 1995
Report at 71.

               Moreover, even in the absence of the current interconnections,
the wheeling contract and the common power pool membership, the Applicants'
proposal to construct additional transmission facilities at the minimal
estimated cost of $4,400,000 would satisfy the integration requirements of the
Act. The Commission has indicated that a single integrated system exists based
solely on a planned, future interconnection, provided that such physical
interconnection is "contemplated or . . . possible within the reasonably near
future" and not just something that "might occur in the remote future, and whose
occurrence has not been foreshadowed by any facts shown in the record." In re
North American Co. and Its Subsidiaries, Holding Co. Act Release No. 4505 (Apr.
15, 1942); In re Cities Service Power & Light Corp., Holding Co. Act Release No.
5256 (Aug. 30, 1944) (integration standard met where "Derby contemplates the
construction of such interconnection facilities").

                  The transmission systems of IEC East and IEC West are not
directly connected currently. However, integration of the IEC East and IEC West
systems for purposes of accomplishing joint economic dispatch and reserve
sharing will be accommodated initially through the purchase of transmission
service from other utilities. In the long term, the integration will be made
through construction of transmission ties directly linking IEC East to IEC West.

<PAGE>   26
                  The specific plan for integration of IEC East and IEC West is
as follows. During the first three years of the merger (1998-2000), IEC will
utilize firm transmission service which has already been purchased for this
purpose from other utilities to allow the needed integration. The specific
transmission purchases are 150 MW of firm from Commonwealth Edison ("ComEd") and
50 MW of firm from Dairyland Power Cooperative ("DPC"). These contracts each
began on October 1, 1997 and run through September 30, 2000. The Applicants
will report to the Commission on or before the expiration of these contracts on
future integration plans.

                  The current plan for the future integration is to construct
two transmission ties between IPC and WP&L in the year 2000. The specific
construction projects identified in the IEC merger filing were a 4-mile 69 kV
line from Hillside substation in Prairie du Chien, Wisconsin to MacGregor
substation in MacGregor, Iowa and a 3-mile 161 kV line from Nelson Dewey
substation in Cassville, Wisconsin to IPW's Turkey River substation located in
Iowa. The total capacity of these ties is estimated at 250 MW consisting of 50
MW for the 69 kV line and 200 MW for the 161 kV line.

                  The Applicants that will comprise IEC have firm transmission
agreements and anticipate that they will continue to have firm transmission
agreements until such time as the additional lines are built. Thus, if, for some
reason, the transmission ties are not constructed on time or if the future
integration between IEC East and IEC West requires more than the 250 MW of
capacity provided by the two proposed transmission ties, then IEC will continue
to purchase firm transmission service from either ComEd, DPC or Northern States
Power Company ("NSP"). Any of these three parties can currently provide the
direct transmission link between IEC East and IEC West. The capacities of the
ComEd, DPC and NSP transmission ties between IEC East and IEC West are currently
1086 MW, 464 MW and 336 MW respectively.

                  In the event that construction of the transmission
reinforcements described above has not begun within 180 days of the scheduled
termination of the currently effective transmission agreements, IEC will
initiate discussions with ComEd and DPC with the intent of extending the term of
the agreements. In the event that these discussions do not result in an
agreement to extend the term within 120 days of the scheduled termination of the
agreements, IEC will make arrangements to take short-term firm transmission
service under the then-effective open access transmission tariffs of ComEd, DPC
or NSP, or in the alternative, will submit a good faith request for long-term
firm transmission service under Section 211 of the FPA.

                  ComEd is currently interconnected with IEC East by means of a
345 kV line that runs from ComEd's Wempletown substation to the Paddock
substation in IEC East. This line has a capacity of 1086 MW, which is the
limiting segment of the IEC East-IEC West transmission path through ComEd. ComEd
is, in turn, interconnected with IEC West through two lines, rated at 345 kV and
138/161 kV, and having an aggregate capacity of 1,124 MW. The 345 kV line
connects ComEd's Quad Cities generating station with IEC East's Rock Creek
substation.


                  DPC is currently interconnected with IEC East by means of five
69 kV lines and one 138/161 kV line. The capacity of these six lines is 464 MW,
which is the limiting interface for the IEC East-IEC West transmission path
through DPC. DPC is, in turn, interconnected with IEC West by 32 separate
transmission lines, 11 of which are rated at 161 kV and the remaining 21 of
which are rated at 69 kV. The aggregate capacity of all of these transmission
lines is 1,004 MW. In addition, regional developments such as the MAPP
Independent System Operator ("ISO") and the Midwest ISO are currently underway.

                  WPL has a projected native load of 2169 MW and firm off-system
sales of 251 MW for 1998. WPL owns generation capacity totaling 2350 MW. WPL has
also purchased 421 MW of firm capacity for 1998. IPW has a projected native load
of 1105 MW and firm off-system sales of 179 MW for 1998. IPC owns generation
capacity totaling 1028 MW. IPC also has purchased firm capacity of 333 MW for
1998. IES's projected native load for 1998 is 1820 MW. IES has no firm
off-system sales. IES owns generation capacity totaling 1853 MW and has
purchased firm capacity for 1998 totaling 245 MW.

                  Because the WPL system is not directly interconnected with
either the IES system or the IPW system, WPL has purchased a total of 200 MW of
firm transmission service between the IPW system and the WPL system for a three
year period, commencing October 1, 1997 and continuing through September 30,
2000. 150 MW of this firm transmission service was purchased from Commonwealth
Edison and the remaining 50 MW of the firm transmission service was purchased
form Dairyland Power Cooperative. The Commonwealth Edison and the Dairyland
Power Cooperative systems are directly interconnected with both the WPL and the
IPW systems. 50 MW of the total 200 MW of firm transmission service purchased by
WPL are reserved for the use of third parties. The remaining 150 MW is
sufficient for and will be used by Interstate Energy Corporation postmerger for
transferring capacity and energy between WPL and IPW for the purposes of
optimizing economic dispatch of the generation resources of IEC as a whole and
providing reliability support for the loads in all areas of the IEC system. 

                 The IPW and IES systems are directly interconnected by means
of a number of transmission lines at voltage levels of 69 kV, 161 kV and 345
kV. The cumulative tie capacity of all these interconnections is 1620 MW. This
tie capacity will likewise be used for the purposes of optimizing economic
dispatch of the generation resources of IEC as a whole and providing
reliability support for the loads in all areas of the IEC system.

                 All of the above interconnections are depicted on maps attached
as Exhibit G-4.

         4.      Gas Coordination.

                 The following table sets forth certain information with respect
to the gas  operations of  Interstate  Energy pro forma as of December 31, 1995,
adjusted to give effect to the Transaction (before intercompany eliminations).

                 WP&L  presently  provides  natural  gas  service  at  retail in
Wisconsin.  South  Beloit  provides  gas  service  in the area of South  Beloit,
Illinois  which is  adjacent to and  interconnected  with the WP&L  system.  IPC
presently  provides gas service in northern  Iowa and southern  Minnesota and in
northwestern Illinois and eastern Iowa. Utilities presently provides gas service
throughout Iowa. Upon  consummation of the Transaction,  the WP&L, South Beloit,
IPC and Utilities gas  operations  will continue to serve this  contiguous  four
state area. The combined gas service  territories of WP&L, South Beloit, IPC and
Utilities after the Transaction are shown in Exhibit G-5.

                 The gas  systems  of (i) WP&L and  South  Beloit,  (ii) IPC and
(iii) Utilities,  respectively,  each presently operates as a single coordinated
system.  While  the WP&L,  IPC and  Utilities  gas  systems  are not  physically
interconnected,  they will functionally  perform as a coordinated system through
purchase of natural gas from common sources of supply,  delivery  through common
interstate pipelines (all of which are open access transportation-only pipelines
under  FERC  Order  636)  and  storage  of gas  in  common  underground  storage
facilities.

                 WP&L,  IPC  and  Utilities  are  served  through  a  "grid"  of
interstate  pipelines  that serve the four  state  region.  Underground  storage
providers are also attached to such grid. A map of this grid is shown as Exhibit
G-6. This grid allows the coordination of gas purchases and delivery in a manner
analogous  to  the   coordination   created  by  the  electric   generation  and
transmission grid.

                  Northern Natural Gas Company ("NNGC") presently provides WP&L
with approximately 50% of its gas requirements, provides IPC with approximately
33% of its gas requirements and IES with approximately 50% of its gas
requirements. Thus, each of the three companies that will comprise IEC receive
a large portion of its gas supplies from NNGC. WP&L has access to 35 gas gates
in NNGC's Zone D; IPC has access to 2 gates in Zone D; IES has access to 28
gates in Zone D. IPC also has access to 24 NNGC gates in Zone E-F and IES has
access to an additional 87 gates in NNGC Zone B-C. Each customer can specify
delivery of gas to any individual gate within a specific zone. For an added
charge, an arrangement can be made to deliver gas from one zone to another.
NNGC is clearly the backbone of the proposed IEC system. The gas lines of
Northern Border Pipeline Company ("NBPC") intersect NNGC pipelines in the IEC
service area. NNGC transports gas primarily from Texas; NBPC transports gas
primarily from Canada. Therefore, the Applicants have a significant common
source of supply and delivery and fulfill that requirement of Section
2(a)(29)(B) of the 1935 Act for an "integrated (gas) public-utility system."

                  Services has begun to implement the specific plans to manage
internally IEC's gas supply procurement system to achieve cost savings for the
holding company system. The general manager of Energy Portfolio Management
("Portfolio") for Services will make decisions on optimum configuration of the
capacity and supply portfolios for the three utility companies that comprise
IEC. The employees who will be responsible for performing the gas capacity and
supply procurement functions of Portfolio will be employees of Services.
Although the employees who procure gas for one utility will not be distinguished
from the employees who procure gas for the other utilities, the employees will
still have to forecast requirements, procure gas and capacity in accordance with
those forecasted requirements, and dispatch to meet those requirements by
utility jurisdiction. This central management of the gas procurement function
will, over time, improve efficiency and reduce overall costs as duplicative
functions and excess reserve capacity are eliminated. The Applicants estimate
the annual savings to be achieved through these enhanced efficiencies to be
$27.4 million.

As a result of FERC Order 636 regarding  restructuring,  WP&L, IPC and Utilities
are now able to directly  purchase  wholesale  natural gas at the  wellhead  (or
processing  plant  outlet,  hub,  or  gathering  system  outlet)  from  numerous
independent "third party" suppliers.  However,  WP&L, IPC and Utilities purchase
significant quantities of natural gas from common supply fields.

The three companies  procure some gas supplies from common  producers.  However,
there are hundreds of natural gas producers available in the marketplace.  Since
restructuring  of gas supply  under FERC Order 636 was  designed  to allow local
distribution  companies  ("LDCs") to directly  contract with any producers  they
wish, and allow the three  companies to use  competitive  bidding  procedures to
select  their  respective  suppliers,  the fact  that  WP&L,  IPC and  Utilities
purchase  supplies  from  different  suppliers  within the common  pools  simply
indicates  that FERC's policy  objective of robust supply  competition  is being
achieved.

               IEC intends to operate the presently separate gas operations of
the Applicants as a single centrally managed and coordinated integrated gas
system within the meaning of Section 2(a)(29)(B) of the Act. Central to the
coordinated operation of the gas system is the procurement of gas supplies. The
gas companies share common sources of supply and receive gas transportation
services from NNG, NGPL, ANR, Viking Natural Gas Pipeline and Northern Border
Pipeline Company. Upon consummation of the Transaction, the gas procurement
component of the gas operations of the Applicants will be centrally managed
through Interstate Services.
                  Additionally, as existing gas supply contracts between the
individual utilities and their suppliers terminate in the ordinary course, it is
expected that Interstate Services, rather than the separate utilities, will
contract for future gas supplies. The greater economies of scale as a result of
coordinated gas procurement are expected to generate further cost savings. It is
also expected that, over time, the utilities will enter into a gas coordination
agreement to detail how pipeline and gas supply costs attributable to the
centralized procurement function are to be allocated between the utilities. PSCW
R. at 799. Any such gas coordination agreement would be subject to state
commission approval. Id.

                  In sum, the coordinated gas operations of the gas properties
of the Applicants will commence immediately through the centralization of
management and day-to-day operating functions at Interstate Services. Full
integration will be achieved over time as existing individual gas contracts are
replaced with contracts covering the entire system.

                 As of December  31, 1995,  IES'  non-utility  subsidiaries  and
investments  constituted  approximately  20% of IES'  assets  on a  consolidated
basis.  Operating  revenues from IES'  non-utility  subsidiaries and investments
were  approximately  12% of IES' consolidated  total operating  revenues for the
year ended  December 31, 1995.  A corporate  chart of IES and its  subsidiaries,
including its non-utility interests, is filed herewith as Exhibit H-2. A
description of IES non-utility interests is filed in Exhibit M-5.

                 IES wholly owns one direct non-utility subsidiary,
Diversified, which was formed in 1992 as a holding company for substantially
all of IES' non-utility businesses.  Diversified has four direct, wholly-owned
subsidiaries, IES Transportation Inc.  ("Transportation"), IES Energy Inc.
("Energy"), IES Investments Inc. ("Investments") and IES International Inc.
("International").

                 c.       IPC

                 IPC's non-utility  subsidiary and investments  constituted less
than 0.2% of IPC's assets on a  consolidated  basis as of December 31, 1995. For
the year ended  December 31, 1995,  there were no operating  revenues from IPC's
non-utility  subsidiary  and  investments.  A  corporate  chart  of IPC  and its
non-utility subsidiary is filed herewith as Exhibit H-2.

                 IPC has one direct  wholly-owned  non-utility  subsidiary,  IPC
Development,  which  acquires  and  disposes of real estate on behalf of IPC and
owns less than 1% of McLeod.  IPC Development's  real estate operations  consist
principally  of buying homes from IPC employees  who have been  relocated by the
company and  purchasing  real  estate  intended  for future use in IPC's  public
utility operations.

                 The information contained in Exhibit M-5 hereto is hereby
incorporated by reference to this Item 1.B.5.

C.       Description of Transaction and Statement as to Consideration

         1.      Background and Negotiations Leading to the Proposed
                 Transaction

                 Each of WPLH, IES and IPC believes 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 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 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 Act.
The exemption from regulation  under the 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.
FERC is in the  process  of  rulemaking  pursuant  to  which  it is  seeking  to
implement,  on  a  comprehensive  basis,  the  comparable  transmission  service
policies it has set forth in these  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 over thirty  states,
including, among others, Wisconsin, Illinois, Iowa and Minnesota, have initiated
proceedings  to review the basic  structure  of the  industry.  These bodies are
considering,  or may  soon  consider,  proposals  to  require  some  measure  of
competition  in the retail portion of the industry.  The PSCW requested  comment
regarding  how the  industry  might be  restructured  in order to  create a more
competitive environment. Following receipt of responses, the PSCW created a task
force to analyze how the industry  might be  restructured  in Wisconsin to allow
consumers  to receive the  benefits of  increased  competition.  On December 19,
1995, following receipt of the report of the task force, the PSCW agreed to take
steps to further increase  competition in Wisconsin's  electric utility industry
within  five  years.  While  the  outcome  of the  actions  described  above  is
uncertain, it remains the view of the management of WPLH, IES and IPC that there
will ultimately be 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.  Each of
WPLH, IES and IPC recognized that a combination with





                                       28
<PAGE>   33

one or more  appropriate  utilities would enable the combined entity to generate
and deliver energy more cheaply and efficiently and thereby remain a competitive
supplier of energy in an increasingly competitive industry.

                 Over  the  last  several  years,  the  management  of WPLH  has
periodically   analyzed  various  potential  strategic  options  that  might  be
available to WPLH,  including  possible business  combinations or alliances with
other utilities. WPLH management considered the possibility of pursuing business
combinations  with a number of the utilities with service areas proximate to the
service area of WP&L, as well as other utilities with Midwestern operations, and
periodically  briefed the WPLH Board on such  matters.  Based on a  cost-benefit
analysis  of  the  potential  strategic  options  considered,   WPLH  management
determined  the options  studied were not in the best  interests of WPLH and its
shareholders.  In early February  1995,  during the  continuation  of one of its
reviews of various strategic alternatives, WPLH management concluded that, among
others,  both IES and IPC were prospective  merger partners that would provide a
good overall  strategic fit. WPLH's  management based its conclusions on various
factors,  including  low-cost  structure,  competitive  energy rates,  potential
merger-related cost savings, economies of scale, marketing potential and similar
shareholder and common stock trading  characteristics.  These reasons,  combined
with the physical  proximity of the respective  companies' service areas and the
compatibility   of  and  similarity   between  the  companies'   operations  and
management, made IES and IPC natural combination partners for WPLH.

                 IES has believed for many years that  consolidation of electric
utilities  within the State of Iowa would be both desirable and  inevitable.  In
July 1991,  Iowa Southern Inc. and IE  Industries  Inc.  merged to form IES. The
utilities in that merger,  Iowa  Southern  Utilities  Company and Iowa  Electric
Light and Power Company,  merged in December 1993 to form  Utilities.  Since the
1991  merger,   management  of  IES  has  continued  to  assess  other  possible
combination transactions both in the State of Iowa and generally in the Midwest.
In December 1992, IES acquired certain electric utility assets and properties in
Iowa from  Union  Electric  Company.  Preliminary  discussions  with  respect to
consolidation  transactions were held from time to time between  representatives
of IES and  other  utilities  in the  Midwest,  including  IPC.  IES  management
recognized  that in the  increasingly  competitive  market for  electric  power,
important  criteria would include low cost  production,  efficiencies  of scale,
transmission  capability,  as well as cultural fit between possible partners and
resolution of corporate  governance  and other  issues.  In December  1994,  IES
determined  to pursue  aggressively  process  reengineering  to reduce costs and
create  efficiencies in its electric and gas utility  businesses.  Management of
IES  continued  to  consider  potential  combination  transactions  both  as  an
additional  means  of  realizing  higher  efficiency  levels  and as a means  to
increase shareholder value.

                 For the past several years, IPC has been monitoring the changes
occurring  in the electric and gas utility  industry  and  conducting  strategic
planning in an effort to remain competitive in the changing environment.  During
that  time,  IPC has been  approached  by  representatives  of  other  utilities
(including IES) in connection with potential business combinations,  but has not
held substantive discussions on any specific proposed combination.





                                       29

During the eighteen months prior to the execution of the Merger  Agreement,  the
management of IPC analyzed  various  potential  strategic  options that might be
available  to  IPC,  including  possible  business   combinations  or  strategic
alliances with other utilities,  as well as options that could be pursued by IPC
on a stand-alone basis. In examining these potential strategic initiatives,  IPC
management  determined that, at that time, and based upon the circumstances then
existing,  IPC and its  stockholders  would be best served by a strengthening of
IPC on a stand-alone  basis. This determination was made by IPC management based
upon its subjective  assessment of the potential benefits and potential risks of
each of the alternatives  considered.  In April 1995, IPC management proposed to
the IPC Board,  and the IPC Board  approved,  a series of strategic  steps to be
pursued  by  IPC  on  an  independent  basis.  These  strategic  steps  included
initiatives to: increase  energy sales  consistent with efficient  energy usage;
enhance efforts to improve productivity and efficiency; leverage existing skills
and resources to increase  revenues and earnings through new service  offerings;
focus the core  energy  service  business  to be  customer  driven;  prepare the
generation segment for potential  unregulated market;  intensify efforts to earn
the allowed rate of return in all jurisdictions in which IPC does business;  and
investigate the potential for diversification into non-core businesses.

                 Over the last several years, as the foregoing issues were being
considered by the management of each of WPLH, IES and IPC, Lee Liu,  Chairman of
the Board,  President & Chief Executive Officer of IES ("Mr. Liu") and Erroll B.
Davis, Jr., President and Chief Executive Officer of WPLH ("Mr. Davis"), and Mr.
Liu and  Wayne H.  Stoppelmoor,  Chairman  of the  Board,  President  and  Chief
Executive  Officer  of  IPC  ("Mr.   Stoppelmoor"),   held  general  discussions
concerning the evolving nature of the electric  utility  industry.  In May 1995,
Mr.  Davis  called Mr. Liu to  schedule a meeting to discuss in a more  focussed
manner the views of WPLH and IES regarding  the future of the utility  industry.
That call  resulted  in a meeting  on May 18,  1995 at which  the  concept  of a
business  combination between WPLH and IES and a subsequent  combination between
the combined WPLH/IES and IPC were discussed in a very preliminary  fashion.  At
that meeting,  Messrs.  Davis and Liu also  identified  the issues of management
succession,  board  composition  and various utility  integration  strategies as
significant  points in any such  business  combination  to be agreed  upon,  and
agreed  that  discussions  between  representatives  of WPLH and IES  should  be
initiated. Such discussions commenced shortly thereafter.

                 WPLH subsequently engaged Merrill Lynch, Pierce, Fenner & Smith
Incorporated ("Merrill Lynch") as its exclusive financial advisor to assist WPLH
in analyzing, structuring,  negotiating, and effecting the possible transaction.
In addition,  WPLH engaged  Foley & Lardner,  its outside law firm, to advise it
with respect to the potential business combination.

                 IES  engaged  Morgan  Stanley  &  Co.   Incorporated   ("Morgan
Stanley") as its financial advisor in connection with this possible  transaction
and also retained its outside law firm, Winthrop,  Stimson, Putnam & Roberts, to
assist it in the potential business  combination.  In addition,  Arthur Andersen
Economic  Consulting was engaged to assist the IES Board and management in their
consideration  of strategic  alternatives,  particularly in the area of possible
synergies  and/or cost savings that could be obtained  from various  alternative
combination





                                       30
<PAGE>   35

transactions  and as compared to cost savings  which  management of IES believed
could be obtained on a stand-alone basis through process reengineering.

                 During  the time  that  discussions  were  being  held  between
representatives  of WPLH  and IES,  representatives  of IPC  were  contacted  to
determine if IPC was interested in discussing a potential business  combination.
The  IPC  Board  subsequently   authorized  its  representatives  to  meet  with
representatives  of IES and WPLH to  discuss a  potential  business  combination
among the companies.

                 IPC   subsequently   engaged  Salomon  Brothers  Inc  ("Salomon
Brothers")  as its financial  advisor to assist IPC in  analyzing,  structuring,
negotiating and effecting the possible three-way transaction and engaged the law
firm of Milbank,  Tweed,  Hadley & McCloy to advise it with respect thereto.  In
addition,  IPC  engaged  the  Deloitte & Touche  Consulting  Group  ("Consulting
Group") to assist IPC's  management in identifying  other potential  combination
partners and in assessing the relative attractiveness of each of these potential
partners, including WPLH and IES, from the standpoint of the potential synergies
described by management  which could be realizable from such a transaction.  IPC
management,   with  the  assistance  of  Consulting  Group,  identified  certain
financial  factors,  such as financial strength and earnings growth, and certain
operational  factors,  such as  customer  mix and  capacity  mix,  that would be
relevant to the IPC Board's  assessment of the relative  attractiveness of other
potential  combination  partners.  This  information,  based  only  on  publicly
available  information  and  certain  attributes  regarding  the  financial  and
operational profile of these potential partners,  was presented to the IPC Board
to describe potential areas of synergies.

                 Consulting Group was subsequently retained to assist the senior
managements of all three companies and certain  employees  designated by them in
identifying and quantifying the potential cost savings from synergies  resulting
from the proposed  three-way merger.  The scope of Consulting Group's engagement
(as  with  its  earlier  engagement  by  IPC)  was  limited  to  assisting  such
managements and designated employees in the identification and quantification of
potential  combination  synergies,  including  personnel  reductions,  non-labor
savings, field operations,  electric dispatch,  capacity deferral and gas supply
savings;  the  assessment  of  impacts  of current  stand-alone  cost  reduction
initiatives  on  merger-related  savings;  quantification  of costs  to  achieve
identified savings; and developing summary presentation materials and supporting
documentation.  Managements  of the three  companies  were  responsible  for the
assumptions and conclusions  made in the synergy study.  While  Consulting Group
assisted such managements in the synergy  identification and estimation process,
the  determination  of synergy  estimates  were the sole  responsibility  of the
managements of the three companies.  Consistent with its assignment,  Consulting
Group did not prepare any financial projections, feasibility studies or reports,
or assist the three companies with financial evaluation or modeling of potential
combination scenarios.

                 To   facilitate   consideration   of  the   proposed   business
combination,  the three  companies  formed  task  forces to review and  evaluate
issues associated with the transaction. During the following months, the various
task forces continued their work with respect to the





                                       31
<PAGE>   36

synergistic  analyses,  business plans, legal structures,  regulatory plans, due
diligence and employee benefits. In addition, discussions continued between WPLH
management  and  Merrill  Lynch,  IES  management  and Morgan  Stanley,  and IPC
management  and Salomon  Brothers  with respect to  negotiation  of the exchange
ratios, and between counsel for the three companies with respect to the terms of
drafts of the mergers and stock option agreements.  Numerous briefings were also
made  by  management  and the  outside  advisors  to the  respective  Boards  of
Directors of WPLH, IES and IPC.

                 Prior to  November  10,  1995,  the  three  companies  with the
assistance  of their  respective  financial  and  legal  advisors  agreed on 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 WPLH, IES and
IPC prior to the completion of the Transaction  and various other matters,  such
as employee benefits and workforce matters. Discussions were also held among Mr.
Davis, Mr. Liu and Mr.  Stoppelmoor and among Merrill Lynch,  Morgan Stanley and
Salomon  Brothers  regarding the exchange ratios to be applied to the IES Common
Stock and the IPC Common Stock.  After  consulting  and  reviewing  with Merrill
Lynch the range of exchange  ratios  previously  presented by Merrill  Lynch and
discussed with the WPLH Board,  as well as the  discussions  among the companies
and their  financial  advisors  regarding the exchange  ratios,  WPLH management
proposed  ratios to IES and IPC which would  result in each share of WPLH Common
Stock remaining outstanding as one share of Interstate Energy Common Stock, each
share of IES Common  Stock being  converted  into 0.98 of a share of  Interstate
Energy Common Stock and each share of IPC Common Stock being converted into 1.11
shares of Interstate Energy Common Stock.

                 On November 10, 1995,  the Boards of Directors of WPLH, IES and
IPC each approved the Merger Agreement,  and certain related  agreements and the
transactions  contemplated  thereby.  The Merger  Agreement and certain  related
agreements were executed on that date.

                 In mid-April 1996, Morgan Stanley,  on behalf of IES, contacted
Merrill  Lynch and informed  Merrill  Lynch that IES desired to discuss  certain
issues  regarding  the Merger  Agreement  and  specifically  IES'  investment in
McLeod.  Morgan  Stanley noted that the potential  value of IES' stake in McLeod
might be above that contemplated at the time the parties originally entered into
the Merger  Agreement.  Following the passage of the  Telecommunications  Act of
1996,  in  April  1996,  McLeod  had  filed a  registration  statement  with the
Commission  with  respect to an initial  public  offering  of its Class A common
stock.

                 During the following weeks, the parties,  in consultation  with
their  financial  and legal  advisors,  discussed  proposals  to provide  for an
adjustment of the IES exchange ratio. On May 7, 1996, the Boards of Directors of
WPLH and IES approved a proposed  amendment to the Merger Agreement which, among
other things,  provided for an adjustment of the IES exchange ratio from 0.98 to
1.01 in the event certain contingencies were satisfied relative to the





                                       32
<PAGE>   37
McLeod initial public offering. The Board of Directors of IPC approved
the amendment on May 10, 1996. The amendment to the Merger Agreement was
executed by the parties on May 22, 1996.

         On June 14, 1996, McLeod completed its initial public offering
and the conditions precedent to an adjustment of the IES exchange ratio were
satisfied. As a result, the IES exchange ratio was automatically adjusted to
1.01.

         On August 4, 1996, MidAmerican Energy Company ("MEC") made an
unsolicited takeover proposal for IES, which was delivered in a letter to IES
(the "MEC Takeover Proposal"). The MEC Takeover Proposal was premised upon the
withdrawal by IES from its proposed transaction with WPLH and IPC. After
consulting with its advisors, the IES Board concluded on August 14, 1996, that,
from a strategic perspective, the Mergers would be more beneficial to IES and
its shareholders, customers and employees in the communities that IES serves
than the MEC Takeover Proposal would be.

         On August 15, 1996, the WPLH Board, the IPC Board and the IES
Board agreed to increase the IES exchange ratio to 1.14. The parties thereafter
executed and delivered Amendment No. 2 to the Merger Agreement, dated as of
August 16, 1996, increasing the IES exchange ratio to 1.14. On September 5,
1996, the Transaction was approved by the shareholders of WPLH and IPC at their
respective meeting and, based on preliminary tabulations, was approved by the
shareholders of IES at its meeting held on September 5, 1996.

         Additional information regarding the background of the
Transaction is set forth in the Joint Registration Statement on Form S-4 of WPLH
and New IPC which is attached as Exhibit I-1 hereto.

     2.   Merger Agreement

         The Merger Agreement provides for IES to be merged with and
into WPLH (at or prior to which time WPLH will change its name to
Interstate Energy), and Acquisition to be merged with and into IPC. The Merger
Agreement is incorporated by reference as Exhibit B.

         Under the terms of the Merger Agreement, upon consummation of the
Transaction: (i) each outstanding share of IES Common Stock (other than shares
owned directly or indirectly by WPLH, IES or IPC and IES Dissenting Shares) will
be converted into the right to receive 1.14 shares of Interstate Energy Common
Stock; (ii) each outstanding share of IPC Common Stock (other than shares owned
directly or indirectly by WPLH, IES or IPC) will ultimately be converted into
the right to receive 1.11 shares of Interstate Energy Common Stock; (iii) each
outstanding share of IPC Preferred Stock (other than shares owned directly or
indirectly by WPLH, IES or IPC and other than IPC Dissenting Shares) will remain
outstanding and unchanged, and (iv) each outstanding share of WPLH Common Stock
will remain outstanding and unchanged as one share of Interstate Energy Common
Stock. As a result of the Transaction, the common shareholders of WPLH, IES and
IPC immediately prior to the Transaction (except for holders of IES Dissenting
Shares) will all be common shareholders of Interstate Energy. The alternative
structure for consummating the mergers as contemplated by the Merger Agreement
will not be utilized by the parties because the PSCW issued a final order
determining that the reincorporation mergers provided for in such alternative
structure were not required. Based on the capitalization of WPLH, IES and IPC on
August 15, 1996 and the exchange capitalization of WPLH, IES and IPC on August
15, 1996 and the exchange ratios for the IES Common Stock and the IPC Common
Stock, holders of WPLH Common Stock, IES Common Stock and IPC Common Stock would
have held approximately 40.8%, 45.1% and 14.1%, respectively, of the aggregate
number of shares of Interstate Energy Common Stock that would have been
outstanding if the Transaction had been consummated as of such date.


                                       33
<PAGE>   38

                 Except as set forth below, if any holder of IES Common Stock or
IPC Common  Stock would be entitled to receive a number of shares of  Interstate
Energy  Common  Stock that  includes a  fraction,  then in lieu of a  fractional
share,  such holder will be entitled  to receive a cash  payment  determined  by
multiplying  the  fractional  share interest by the average of the last reported
sales  price,  regular way, per share of WPLH Common Stock on the New York Stock
Exchange  Composite  Tape for the ten business  days prior to and  including the
last  business day prior to the  consummation  of the  Transaction,  without any
interest  thereon.  Fractional  shares of IES Common  Stock and IPC Common Stock
held in accounts  under the dividend  reinvestment  plans and  employee  benefit
plans of IES and IPC may be converted into the  applicable  number of shares (or
fractional  shares) of Interstate  Energy  Common Stock in  accordance  with the
respective exchange ratios.

                 The  Transaction  is subject to customary  closing  conditions,
including the approval of the Commission.

                 The   Transaction   is   designed  to  qualify  as  a  tax-free
reorganization  under  Section  368 of the  Internal  Revenue  Code of 1986,  as
amended.  WPLH,  IES and IPC believe that the  Transaction  will be treated as a
"pooling of interests" for accounting purposes.

                 The Merger Agreement contains certain covenants relating to the
conduct of business by the parties pending the  consummation of the Transaction,
which are customarily contained in merger transactions  generally.  As a general
matter,  the  parties  must carry on their  businesses  in the  ordinary  course
consistent  with past  practice,  may not increase  dividends  beyond  specified
levels,  and may not issue  capital  stock  except as otherwise  specified.  The
Merger  Agreement also contains  customary  restrictions on, among other things,
charter and bylaw amendments, capital expenditures,  acquisitions, dispositions,
incurrence  of  indebtedness,  certain  increases in employee  compensation  and
benefits and affiliate transactions.

         3.      Management of Interstate Energy Following the Merger.

                 Following consummation of the Transaction,  the headquarters of
Interstate  Energy  will  be in  Madison,  Wisconsin.  Pursuant  to  the  Merger
Agreement, upon consummation of the Transaction,  the Interstate Energy Board of
Directors will consist of fifteen members:  six designated by IES (including Mr.
Liu), six designated by WPLH  (including Mr. Davis) and three  designated by IPC
(including Mr.  Stoppelmoor).  As of the date hereof, WPLH, IES and IPC have not
determined which individuals, in addition to Messrs. Liu, Davis and Stoppelmoor,
will be designated to serve as directors of Interstate  Energy upon consummation
of the Transaction.

                 Upon  consummation  of the  Transaction,  Mr. Liu will serve as
Chairman  of the Board of  Directors  of  Interstate  Energy for a period of two
years and  thereafter  will  retire as an officer of  Interstate  Energy but may
continue as a director of Interstate  Energy.  Mr. Davis will serve as President
and Chief  Executive  Officer  of  Interstate  Energy  for a period of two years
following the effective date of the Transaction  and, for the three-year  period
thereafter and following Mr. Liu's retirement, Mr. Davis will serve as Chairman,
President and Chief Executive Officer of Interstate Energy. Mr. Stoppelmoor will
serve as Vice Chairman of Interstate  Energy for a period of two years following
the effective date of the  Transaction  and thereafter will retire as an officer
of  Interstate  Energy but may  continue  as a director  of  Interstate  Energy.
Messrs.  Liu, Davis,  Stoppelmoor and Michael R. Chase (Executive Vice President
of IPC) will each have an employment  agreement with Interstate Energy following
the  consummation of the Transaction.  The forms of these employment  agreements
are  attached as Annexes H, I, J and K to the Joint  Registration  Statement  on
Form S-4 and are incorporated by reference herein as Exhibit I-2.

                 Following  consummation of the  Transaction,  the activities of
Interstate  Energy will be governed  by its  Amended  and  Restated  Articles of
Incorporation  and  Restated  Bylaws,  attached  hereto as Exhibits J-1 and J-2,
respectively.

D.       Dividend Reinvestment Plan, Long-Term Equity Incentive Plan and other
         Employee Benefit Plans.

                 Interstate  Energy proposes,  from time to time during a period
of five  years  from the date of an Order  issued  by the  Commission,  to issue
and/or  acquire in open  market  transactions  or  through  privately-negotiated
transactions  up to 11 million  shares of  Interstate  Energy Common Stock under
Interstate  Energy's  dividend  reinvestment and stock purchase plan,  long-term
equity incentive plan and certain other employee benefit plans described below.

1.       Dividend Reinvestment Plan

                 Each of WPLH, IES and IPC has in place a dividend  reinvestment
and stock purchase plan. Following consummation of the Transaction,  the IES and
IPC plans will cease to exist and participants in such plans will be eligible to
become participants in the WPLH plan,





                                       35
<PAGE>   40

which is  referred  to below as the  "DRIP" and which will  become  (subject  to
certain proposed modifications as described below) the Interstate Energy plan.

                 Set forth below is a description of the principal  terms of the
                 DRIP:

                 a.       Purpose of the DRIP and Eligibility of Participants.

                 The  purpose  of the DRIP is to provide  eligible  participants
with a convenient  and  economical  method of investing  cash  dividends  and/or
optional  cash  payments in shares of  Interstate  Energy  Common  Stock.  To be
eligible to participate in the DRIP, a person will need to be: (i) a shareholder
of record of Interstate  Energy Common  Stock,  (ii) a shareholder  of record of
Preferred Stock of WP&L or (iii) an employee of Interstate  Energy or one of its
majority-owned   subsidiaries.   Directors   of   Interstate   Energy   or   any
majority-owned  subsidiary  will also be eligible to participate in the DRIP. It
is anticipated that prior to the consummation of the Transaction,  the DRIP will
be modified to permit other  investors who are not  shareholders or employees of
Interstate Energy to make an original purchase of Interstate Energy Common Stock
under the DRIP, whereupon they will become shareholders of Interstate Energy and
will be entitled to participate in the DRIP like other shareholders.  It is also
expected that the DRIP will be modified to allow (following  consummation of the
Transaction)  the reinvestment of dividends paid on shares of Preferred Stock of
Utilities and IPC.

                 The  DRIP is  designed  to  encourage  and  facilitate  broader
ownership of Interstate  Energy Common Stock.  Full  investment of funds will be
possible under the DRIP, subject to minimum and maximum purchase limits, because
the DRIP will  permit  fractional  as well as whole  shares to be  credited to a
participant's account. The DRIP will also provide Interstate Energy with a means
to raise equity capital and to increase ownership by small, long-term investors.

                 b.       Sources of Common Stock and Use of Proceeds.

                 Any shares of Interstate  Energy Common Stock  purchased  under
the DRIP with optional cash  payments or  reinvested  dividends  will be, at the
discretion of Interstate Energy, authorized but unissued shares, treasury shares
or shares purchased on the open market or in privately  negotiated  transactions
by the DRIP's independent plan administrator  (the  "Administrator").  As of the
date of this  Application,  the  Administrator is purchasing  shares in the open
market  for the  WPLH  plan.  Following  consummation  of the  Transaction,  the
decision  as to whether  shares are to be  purchased  directly  from  Interstate
Energy, or in the open market or in privately negotiated  transactions,  will be
based on Interstate Energy's need for common equity and other factors considered
by Interstate  Energy to be relevant.  Any determination by Interstate Energy to
alter  the  manner  in  which  shares  will  be  purchased  for  the  DRIP,  and
implementation  of  any  such  change,  will  comply  with  applicable  law  and
Commission interpretations then in effect.





                                       36
<PAGE>   41

                 Net proceeds from the sale of newly issued shares of Interstate
Energy  Common Stock will be added to  Interstate  Energy's  general funds to be
available for general corporate purposes. Interstate Energy will not receive any
proceeds  from  shares  acquired by the  Administrator  in the open market or in
privately negotiated transactions.

                 Interstate  Energy will not use any proceeds  from newly issued
shares to  acquire  the  securities  of or any  interest  in any EWG or  foreign
utility companies (as those terms are defined in Sections 32(e) and 33(a) of the
Act, as amended by the Energy  Policy Act of 1992),  until such time as such use
shall be approved by regulation or order of the  Commission,  to the extent such
approval is required under the Act.

                 A full  statement  of the  current  provisions  of the  DRIP is
included in WPLH's Registration Statement on Form S-3 (Exhibit I-3 hereto).

2.       Long-Term Equity Incentive Plan.

                 WPLH  currently  has in effect the Long-Term  Equity  Incentive
Plan  (the  "Long-Term   Plan")  which  will  remain  in  effect  following  the
consummation  of the  Transaction.  In addition to providing the opportunity for
awards to key employees of Interstate Energy and its subsidiaries  following the
consummation of the  Transaction,  the Long-Term Plan is expected to replace the
IES Long-Term  Incentive Plan (the "IES Long-Term Plan") (except with respect to
obligations  incurred  thereunder prior to the consummation of the Transaction).
Pursuant to the Merger Agreement, (i) each outstanding option to purchase shares
of IES  Common  Stock  under the IES  Long-Term  Plan along  with  tandem  stock
appreciation rights will be modified such that the option will constitute at the
effective  time of the  Transaction  the right to acquire (on the same terms and
conditions as were  applicable  under such option)  shares of Interstate  Energy
Common  Stock based on the same  number of shares of  Interstate  Energy  Common
Stock as the holder of such IES stock option would have been entitled to receive
in the  Transaction  had such holder  exercised such option in full  immediately
prior to the  consummation of the Transaction;  and (ii) each other  outstanding
award under the IES  Long-Term  Plan shall be modified  to  constitute  an award
based upon the same number of shares of  Interstate  Energy  Common Stock as the
holder of such award would have been entitled to receive in the  Transaction had
such  holder  been  the  owner,  immediately  before  the  consummation  of  the
Transaction, of the shares of IES Common Stock on which such award is based, and
otherwise  on the same terms and  conditions  as govern  such award  immediately
before the consummation of the  Transaction.  IES also has in effect the Whiting
Stock Option Plan pursuant to which one remaining participant  thereunder has an
option  to  acquire  IES  Common  Stock.  It is  anticipated  that  prior to the
consummation of the Transaction  such option will be exercised or such Plan will
be  amended  to  provide  that the  option  will be  exercisable  for  shares of
Interstate Energy Common Stock based on the IES exchange ratio.

                 Set  forth  below  is a  summary  of  certain  features  of the
Long-Term  Plan,  which  summary is qualified by reference to such plan (Exhibit
I-4 hereto):





                                       37
<PAGE>   42

                 The  Long-Term  Plan  is  required  to  be  administered  by  a
committee  of  the  Interstate  Energy  Board  of  Directors  (the  "Committee")
consisting of not less than two  directors  who are eligible to  administer  the
Long-Term Plan pursuant to Rule 16b-3 under the Securities Exchange Act of 1934.
The Compensation and Personnel  Committee of the WPLH Board is currently serving
as the administrator of the Long-Term Plan. Among other functions, the Committee
has the  authority to establish  rules for the  administration  of the Long-Term
Plan; to select the employees of Interstate  Energy and its subsidiaries to whom
awards  will be  granted;  to  determine  the types of awards to be  granted  to
employees and the number of shares covered by such awards;  to set the terms and
conditions of such awards; to determine whether,  to what extent and when awards
may be settled in cash or shares;  and to amend the terms and  conditions of any
outstanding  awards to the extent authorized under the Long-Term Plan. Except as
otherwise  provided in the Long-Term Plan,  determinations  and  interpretations
with respect to the Long-Term Plan and any award  agreements will be in the sole
discretion of the Committee,  whose  determination and  interpretations  will be
binding on all  parties.  Any  nonunion  employee  of  Interstate  Energy or any
subsidiary,  including any executive officer or  employee-director of Interstate
Energy, is eligible to receive awards under the Long-Term Plan.

                 The Long-Term Plan authorizes the granting to employees of: (a)
stock options,  which may be either incentive stock options ("ISOs") meeting the
requirements  of  Section  422 of the  Internal  Revenue  Code (the  "Code")  or
nonqualified stock options; (b) restricted stock; and (c) performance shares and
performance  units.  The Long-Term Plan provides that up to a total of 1,000,000
shares of  Interstate  Energy  Common Stock  (subject to adjustment as described
below) will be  available  for the  granting of awards.  Of this  number,  up to
300,000  shares may be granted as  restricted  stock.  If any shares  subject to
awards  granted under the Long-Term  Plan,  or to which any award  relates,  are
forfeited or if an award otherwise terminates,  expires or is cancelled prior to
the  delivery  of all of the shares or other  consideration  issuable or payable
pursuant  to the award,  such shares  (assuming  the holder of the award did not
receive  dividends on the shares or exercise other indicia of ownership) will be
available  for the granting of new awards under the Plan.  Any shares  delivered
pursuant to an award may be either  authorized and unissued shares of Interstate
Energy Common Stock or shares reacquired and held by Interstate Energy.

                 Options may be granted to  employees  at such times and in such
amounts as determined  by the  Committee,  provided  that the maximum  number of
shares subject to options that may be granted to any single  participant  during
the term of the  Long-Term  Plan is  150,000.  The  exercise  price per share of
Interstate  Energy Common Stock subject to an option granted under the Long-Term
Plan will be determined by the  Committee,  provided that the exercise price may
not be less than 100% of the fair market value of a share of  Interstate  Energy
Common Stock on the date of grant. In addition,  the Committee may grant options
with  exercise  prices that increase  over time.  The term of an option  granted
under the  Long-Term  Plan will be as determined  by the  Committee,  but cannot
exceed  ten  years.  Options  granted  under  the  Long-Term  Plan  will  become
exercisable  in such  manner  and  within  such  period or  periods  and in such
installments  or otherwise as determined  by the  Committee;  provided,  that no
option may be exercised  within six months of its grant.  All ISOs granted under
the Long-Term Plan will





                                       38
<PAGE>   43

also be required  to comply with all other terms of Section 422 of the Code.  At
the  time  an  option  is  granted,   the  Committee  may  also  grant  dividend
equivalents.  Dividend  equivalents  give the participant a contingent  right to
receive  an amount  equal to the  dividends  declared  on a share of  Interstate
Energy  Common  Stock on all record  dates  during the related  option  exercise
period. Payout of the value of a dividend equivalent will be made in cash within
30 days  following  the exercise of the related  option,  provided the option is
in-the-money on the exercise date.

                 In the event a participant's employment is terminated by reason
of death,  disability or  retirement,  all  outstanding  options  granted to the
participant  will  become  fully  vested and remain  exercisable  prior to their
expiration  or for one year (three years in the case of  retirement),  whichever
period is shorter.  If a  participant's  employment is terminated  for any other
reason (other than for cause),  unvested options held by the participant will be
forfeited,  unless otherwise determined by the Committee, and vested options may
be  exercised  during  the  three  month  period  following  termination.  If  a
participant's  employment  is  terminated  for cause,  all  options  held by the
participant will be forfeited.

                 Shares of restricted  common stock  granted to employees  under
the  Long-Term  Plan will be subject to such  restrictions  as the Committee may
impose,  including a requirement  that  participants  pay a stipulated  purchase
price  for  each  share.  The  restrictions  imposed  on the  shares  may  lapse
separately or in combination at such time or times,  or in such  installments or
otherwise, as the Committee may deem appropriate; provided, that no restrictions
will lapse prior to six months  after award,  except in the case of death.  Upon
termination  of an  employee's  employment  for any  reason  other  than  death,
disability or retirement during the applicable restriction period, all shares of
restricted  stock still subject to restriction  will be subject to forfeiture by
the employee.  In the event an employee's  employment is terminated by reason of
death, disability or retirement, all shares of restricted stock still subject to
restriction  will become fully vested.  Under the Long-Term  Plan, the Committee
will have the  authority at its  discretion  to waive in whole or in part any or
all remaining restrictions with respect to shares of restricted stock granted to
an employee.

                 During the period of  restriction,  participants  may  exercise
full voting rights with respect to restricted shares and are entitled to receive
all regular cash  dividends  paid with respect to those  shares.  All other cash
dividends and distributions may be credited to participants  subject to the same
restrictions on transferability and forfeitability as the restricted shares with
respect to which they are paid.  If any dividends or  distributions  are paid in
shares,  the shares will be subject to the same restrictions on  transferability
as the shares on which the dividends or distributions are paid.

                 The   Long-Term   Plan  also   provides  for  the  granting  of
performance  shares and  performance  units to  employees.  The  Committee  will
determine the number of performance  units and shares  granted to  participants;
provided that so long as the Committee  determines  that a grant of  performance
units or performance shares should qualify for the "performance-based" exemption
under Section 162(m) of the Code, the maximum payout to any executive officer





                                       39
<PAGE>   44

named in the proxy  statement  compensation  table with  respect to  performance
units and/or  performance  shares  granted in any fiscal year is  $400,000.  The
Committee will determine the applicable performance period, which, in all cases,
will exceed six months,  the performance goal or goals to be achieved during any
performance  period,  the  proportion  of  payments,  if  any,  to be  made  for
performance between the minimum and full performance levels and any other terms,
conditions and rights relating to the grant of performance shares or performance
units.  Interstate  Energy and subsidiary  performance  goals established by the
Committee  under the Long-Term Plan will be chosen from return on equity,  total
shareholder return, net income,  earnings per share and cash flow. The Committee
will  establish the specific  goals each year prior to the  commencement  of the
period to which the  compensation  relates.  Payment on  performance  shares and
performance units held by employees will be made in cash or shares of Interstate
Energy Common Stock (which, at the discretion of the Committee, may be shares of
restricted  stock) (or in a combination  thereof),  which have an aggregate fair
market value equal to the value of the earned performance shares and performance
units.  Payments  will be made in a single  lump sum  within  seventy-five  days
following the close of the applicable performance period, unless the participant
elects to defer payment.

                 In the event a participant's employment is terminated by reason
of death,  disability,  retirement or involuntary termination without cause, the
participant  will receive a prorated  payout of the  performance  shares  and/or
performance units as determined by the Committee based on the length of time the
awards were held and the achievement of the  preestablished  performance  goals.
Upon  termination  of a  participant's  employment  for any  other  reason,  all
performance shares and performance units will be forfeited.

                 Participants will be entitled to receive dividends with respect
to shares earned in connection with grants of performance shares and performance
units,  subject to the same accrual,  forfeiture and payout  restrictions  which
apply with respect to shares of restricted stock. In addition, participants may,
at the discretion of the Committee,  be entitled to exercise  voting rights with
respect  to  shares  which  have  been  earned  in  connection  with  grants  of
performance units and performance shares.

                 In the  event  of any  stock  dividend,  stock  split,  merger,
consolidation, reorganization,  recapitalization, share combination, liquidation
or any other change  affecting the  Interstate  Energy Common Stock such that an
adjustment is  appropriate  in order to prevent  dilution or  enlargement of the
benefits or potential benefits intended to be made available under the Long-Term
Plan, then the Committee will generally have the authority, in such manner as it
deems  equitable,  to adjust (i) the number and type of shares of stock that may
be issued under the Long-Term  Plan, (ii) the number and type of shares of stock
subject to outstanding  awards, and (iii) the grant,  purchase or exercise price
with respect to any award.

                 No award  granted  under the  Long-Term  Plan may be  assigned,
sold, pledged,  transferred or encumbered by any participant,  otherwise than by
will, or by the laws of descent and distribution.





                                       40
<PAGE>   45

                 The Interstate Energy Board may amend, suspend or terminate the
Long-Term  Plan  at  any  time,   provided  that  no  amendment  which  requires
shareholder  approval in order for the Long-Term Plan to continue to comply with
Rule 16b-3 under the Securities  Exchange Act of 1934 will be effective  without
approval of shareholders.  Further, no termination, amendment or modification of
the Long-Term  Plan will  adversely  affect in any material way any  outstanding
award without the consent of the holder of such award.

                 The Committee may permit a participant  to defer receipt of the
payment of cash or delivery of shares due with  respect to an award,  subject to
such rules and procedures as the Committee may establish.

                 Upon the  occurrence  of a Change in Control (as defined in the
Rights Agreement) of Interstate  Energy (i) all outstanding  options will become
immediately  exercisable;  (ii) any restriction periods and related restrictions
on restricted stock will lapse; (iii) the target payout  opportunity  attainable
under all outstanding  performance  units and shares will be deemed fully earned
for the  entire  performance  period and a pro rata  portion of the  performance
share or unit, based on the portion of the performance period which has elapsed,
will  be  paid  out  in  cash;  and  (iv)  the  Committee  may  make  any  other
modifications  to outstanding  awards,  except,  in all cases,  unless otherwise
specifically prohibited by the Plan.

3.       Other Stock-Based Employee Benefit Plans

                 Each of WPLH,  IES and IPC currently has plans,  in addition to
the Long-Term  Plan,  the IES Long-Term  Plan and the Whiting Stock Option Plan,
that  provide for the  issuance of shares of its common  stock to  participating
employees.  It is currently anticipated that such plans, the Wisconsin Power and
Light Company Employees' Retirement Savings Plan, the IES Employee Savings Plan,
the IES Employee Stock Purchase Plan, the IES Bonus Stock Ownership Plan and the
Interstate  Power  Company  401(k)  Plan,  will remain in effect  following  the
consummation  of the  Transaction,  except  that such plans will be  modified to
provide for the  acquisition  of Interstate  Energy  Common  Stock.  Each of the
Wisconsin Power and Light Company  Employees'  Retirement  Savings Plan, the IES
Employee  Savings  Plan and the  Interstate  Power  Company  401(k)  Plan allows
participating  employees to elect to defer a portion of their  compensation  and
have  such  funds  invested  in  designated  investment  media  selected  by the
participants,  including  a common  stock  fund of the  sponsoring  company.  In
connection  with the  Transaction,  shares of IES  Common  Stock held in the IES
Employee  Savings  Plan and  shares of IPC Common  Stock held in the  Interstate
Power Company  401(k) Plan will be converted  into shares of  Interstate  Energy
Common Stock and  following the  consummation  of the  Transaction  the employer
common  stock  fund  of each of the  plans  will  provide  for the  issuance  of
Interstate  Energy  Common  Stock.  Each of the  plans is a  qualified  plan for
purposes of Section  401(a) of the Code.  The IES Employee  Stock  Purchase Plan
allows  eligible IES  employees  to purchase  stock at a discount to fair market
value and the IES Bonus Stock Ownership Plan provides a mechanism to award stock
bonuses to nonmanagement employees of IES and its subsidiaries.

                  As soon as practicable after the consummation of the merger,
the Applicants intend to implement a new single IEC 401(k) plan by merging the
401(k) plans of WPLH/WP&L, IPC and IES. The merged IEC 401(k) plan will use the
common stock of IEC.



                                       41
<PAGE>   46

E.       Rights Agreement

                 Applicants  seek   authorization  to  implement  the  following
transactions,  which are permitted by the terms of the Rights Agreement: (i) the
issuance  of the  Rights  (as  defined  below);  (ii) the sale and  issuance  of
Interstate  Energy Common Stock or other Interstate  Energy securities or assets
upon the  exercise  of the  Rights;  (iii) the  redemption  of the Rights or the
issuance of Interstate Energy Common Stock or other Interstate Energy securities
in exchange for the Rights;  and (iv) the  amendment of the Rights  Agreement as
permitted by the terms thereof.

                 Set forth below is a description of the principal  terms of the
Rights Agreement.  Such description is qualified in its entirety by reference to
the text of the Rights Agreement, which is attached hereto as Exhibit I-5.

                 The Rights Agreement  provides that each  outstanding  share of
Interstate  Energy  Common  Stock will have  attached  thereto one Common  Stock
Purchase Right ("Right") and each share subsequently issued by Interstate Energy
prior to the  expiration  of the Rights  Agreement,  including the shares issued
pursuant to the Transaction, will have attached thereto one Right. Under certain
circumstances  described  below,  the Rights will entitle the holder  thereof to
purchase additional shares of Interstate Energy Common Stock.

                 Currently  the  Rights are not  exercisable  and trade with the
WPLH  Common  Stock.  In the event the  Rights  become  exercisable,  each Right
(unless held by a person or group which  beneficially  owns more than 20% of the
outstanding Interstate Energy Common Stock) will initially entitle the holder to
purchase  one-half share of Interstate Energy Common Stock at a price of $60 per
full share  (equivalent to $30 per each one-half share),  subject to adjustment.
The Rights will only become  exercisable  if a person or group has acquired,  or
announced  an  intention to acquire,  20% or more of the  outstanding  shares of
Interstate  Energy Common  Stock.  Under  certain  circumstances,  including the
existence  of a 20%  acquiring  party,  each  holder of a Right,  other than the
acquiring  party,  will be entitled to purchase at the exercise price Interstate
Energy  Common Stock having a market value of two times the exercise  price.  In
the  event of the  acquisition  of  Interstate  Energy  by  another  corporation
subsequent  to a person  acquiring 20% or more of the  Interstate  Energy Common
Stock,  each  holder  of a Right  will be  entitled  to  receive  the  acquiring
corporation's  common  shares  having a market  value of two times the  exercise
price.  The Rights  may be  redeemed  at a price of $.01 per Right  prior to the
existence of a 20% acquiring party and may thereafter be exchanged for one share
of  Interstate  Energy  Common  Stock per Right  until  the  existence  of a 50%
acquiring  party.  The Rights will expire on February 22, 1999. Under the Rights
Agreement,  the  Interstate  Energy Board will be able to reduce the  thresholds
applicable  to the  Rights  from 20% to not less  than  10%.  Rights do not have
voting or dividend rights and, until they become  exercisable,  have no dilutive
effect on the earnings of WPLH.

                 Shareholder  rights plans, such as the Rights  Agreement,  have
become a widely accepted means of maximizing  shareholder  value by reducing the
risk of nonrealization of





                                       42
<PAGE>   47

shareholder value due to opportunistic takeover proposals.  The Rights Agreement
would  encourage  potential  acquirors to negotiate with the  Interstate  Energy
Board and would be intended to assist the  Interstate  Energy Board in obtaining
the highest value for the  shareholders  of Interstate  Energy,  especially in a
hostile or unwanted  takeover  situation.  The Rights  Agreement may, in certain
circumstances,  permit  the  Interstate  Energy  Board to  thwart  an offer  the
Interstate  Energy Board determines to be inadequate.  The Rights Agreement also
provides the Interstate  Energy Board with a role  (supplemental  to the role of
the  Commission  under the Act) in  discouraging  implicitly  coercive  takeover
tactics and is intended to enable the Interstate Energy Board to provide holders
of Interstate  Energy Common Stock  adequate time to properly  assess a takeover
bid without  undue  pressure.  A  shareholder  rights  plan,  such as the Rights
Agreement,  may enhance the probability that a higher competing bid will emerge.
Over 1,700 American public companies have adopted  shareholder rights plans. The
Commission  has authorized  registered  holding  companies to adopt  shareholder
rights plans  substantially  similar to the Rights Agreement.  National Fuel Gas
Company, Holding Co. Act Release No. 26532 (June 12, 1996); Consolidated Natural
Gas Company, Holding Co. Act Release No. 26434 (December 19, 1995).

To the  extent  that  other  sections  of the  Act  or  the  Commission's  rules
thereunder  are deemed  applicable to the  Transaction,  such sections and rules
should be considered to be set forth in this Item 3.

A.       Transaction

                 Section  9(a)(2)  makes it  unlawful,  without  approval of the
Commission  under  Section  10,  "for any person . . . to  acquire,  directly or
indirectly,  any security of any public  utility  company,  if such person is an
affiliate  [under  Section  2(a)(11)(A) of the Act] . . . of such company and of
any  other  public  utility  or  holding  company,  or  will by  virtue  of such
acquisition become such an affiliate." Under the definition set forth in Section
2(a)(11)(A),  an  "affiliate"  of a  specified  company  means "any  person that
directly or indirectly owns, controls, or holds with power to vote, 5 per centum
or more of the outstanding voting securities of such specified company."

                 WP&L,  South  Beloit,  Utilities  and  IPC are  public  utility
companies as defined in Section 2(a)(5) of the Act. Because WPLH, an "affiliate"
of WP&L and South Beloit within the meaning of Section 2(a)(11) of the Act, will
acquire more than five percent of the voting securities of each of Utilities and
IPC as a result of the  Transaction,  and because  WPLH will  thereby  become an
affiliate of Utilities and IPC, WPLH must obtain the approval of the  Commission
for the  Transaction  under  Sections  9(a)(2) and 10 of the Act. The  statutory
standards  to be  considered  by  the  Commission  in  evaluating  the  proposed
transaction are set forth in Section 10 of the Act.

                 As set forth more fully below, the Transaction complies with
all of the applicable provisions of Section 10 of the Act and should be
approved by the Commission.  Thus:

<PAGE>   51

<TABLE>
<S>     <C>
- - -       the Transaction will not create detrimental interlocking relations or concentration of control;
- - -       the consideration to be paid in the Transaction is fair and reasonable;
- - -       the Transaction will not result in an unduly complicated capital structure for the Interstate Energy system;
- - -       the Transaction is in the public interest and the interests of investors and consumers;
- - -       the Transaction is not unlawful under Section 8 and is not detrimental to the carrying out of the provisions of Section 11
        of the Act;
- - -       The Transaction tends toward the economical and efficient development of an integrated electric utility system; and
- - -       the Transaction will comply with all applicable state laws.
</TABLE>

                 The   Transaction   and   the   requests   contained   in  this
Application/Declaration  are well within the precedent of transactions  approved
by the  Commission  as  consistent  with the Act. In  addition,  a number of the
recommendations  made by the Division of Investment  Management (the "Division")
in the report issued by the Division in June 1995  entitled  "The  Regulation of
Public Utility Holding  Companies"  (the "1995 Report")  support the applicants'
analysis.  The Commission's approval of the Transaction would be consistent with
previous  Commission  rulings(8) and would also be consistent  with the
Division's overall   recommendation   in  the  1995   Report  that  the
Commission   "act administratively to modernize and simplify holding company
regulation.  . . and minimize  regulatory  overlap,  while  protecting the
interests of consumers and investors,"(9)  since, as demonstrated  below,  the
Transaction  will benefit both consumers and shareholders of Interstate Energy,
and the other federal and state regulatory  authorities  with  jurisdiction
over  this  Transaction  have approved it as in the public interest.  In
addition,  although discussed in more detail in each  applicable  item below,
the  Transaction is consistent with the specific recommendations of the Division
with regard to financing transactions,(10) utility ownership(11) and
diversification.(12)

         1.      Section 10(b)

                 Section 10(b)  provides  that, if the  requirements  of Section
10(f) are satisfied,  the Commission shall approve an acquisition  under Section
9(a) unless:

                 (1) such acquisition will tend towards  interlocking  relations
         or the concentration of control of public utility companies,  of a kind
         or to an extent  detrimental to the public interest or the interests of
         investors or consumers;

                 (2) in case of the acquisition of securities or utility assets,
         the  consideration,   including  all  fees,   commissions,   and  other
         remuneration,  to whomsoever paid, to be given, directly or indirectly,
         in connection with such  acquisition is not reasonable or does not bear
         a fair relation to the sums invested in or the earning  capacity of the
         utility  assets to be  acquired or the utility  assets  underlying  the
         securities to be acquired; or

                 (3)      such acquisition will unduly complicate the capital
         structure of the holding company system of the applicant or will be
         detrimental to the public interest or the





                                       47
<PAGE>   52

         interests of investors or consumers or the proper functioning of such
         holding company system.

                 a.       Section 10(b)(1)

                          i.      Interlocking Relationships

                 Section  10(b)(1) was primarily  aimed at  preventing  business
combinations unrelated to operating synergies and was never intended to prohibit
mergers that otherwise made operational  sense and were permissible  under other
provisions of the Act.

                As  described  in  Item  1.C.3.  above,  the  Merger  Agreement
provides  for the Board of  Directors  of  Interstate  Energy to be  composed of
fifteen members,  six designated by each of WPLH and IES and three designated by
IPC.(13) In addition,  each of the utility  subsidiaries  of  Interstate  Energy
is expected to enter into a service  agreement with Interstate  Services,  which
is necessary to integrate WPLH, IES and IPC into a single Interstate Energy
system. These  actions are subject to approval of the  Commission  under
Section 13 and state regulatory authorities and will, therefore, be closely
monitored to insure that  they  are in the  public  interest  and the  interests
of  investors  and consumers. Forging such relations is beneficial to the
protected interests under the Act and thus is not prohibited by Section
10(b)(1).  Moreover, the projected benefits  that will  accrue to the  public,
investors  and  consumers  from the combination  of  WPLH,  IES and IPC
demonstrate  that  the  combination  is not detrimental to the protected
interests under the Act.

                          ii.     Concentration of Control

                 Section   10(b)(1)   is   intended   to  avoid  "an  excess  of
concentration and bigness" while preserving the  "opportunities for economies of
scale,  the elimination of duplicate  facilities and activities,  the sharing of
production  capacity and  reserves  and  generally  more  efficient  operations"
afforded by the  coordination  of local  utilities  into an  integrated  system.
American  Electric Power Co., 46 S.E.C.  1299, 1309 (1978).  In applying Section
10(b)(1) to utility  acquisitions,  the Commission  must  determine  whether the
acquisition  will create "the type of structures and  combinations  at which the
Act was specifically directed." Vermont Yankee Nuclear Corp., 43 S.E.C. 693, 700
(1968).  As discussed  below,  the  WPLH-IES-IPC  combination  alliance will not
create a "huge,  complex,  and irrational  system" of a type at which the Act is
directed,  but rather will afford the opportunity to achieve  economies of scale
and efficiencies which are expected to benefit investors and consumers. American
Electric Power Co., 46 S.E.C. 1299, 1307 (1978).

                 Size:  If approved,  the  Interstate  Energy  system will serve
approximately   873,000  retail  electric  customers  and  369,000  natural  gas
customers in four states.  As of and for the year ended  December 31, 1995:  (1)
the combined assets of WPLH, IES and IPC would have totaled approximately $4.492
billion;  (2) combined  utility revenues of WPLH, IES and IPC would have totaled
approximately  $1.755 billion;  and (3) combined owned generating capacity would
have totaled approximately 5,469 MW.





                                       48
<PAGE>   53

                By comparison, the Commission has approved a number of
acquisitions involving significantly larger operating utilities. See, e.g.,
CINergy Corp., Holding Co. Act Release No. 26146 (Oct. 21, 1994) (combination of
Cincinnati Gas & Electric Co.  and PSI Resources; combined assets at time of
acquisition of  approximately $7.9 billion); Entergy Corp., Holding Co. Act
Release No.  25952 (Dec. 17, 1993) (acquisition of Gulf States Utilities;
combined assets at time of acquisition in excess of $21 billion); Northeast
Utilities, Holding Co. Act Release No. 25221 (Dec. 21, 1990) (acquisition of
Public Service of New Hampshire; combined assets at time of acquisition of
approximately $9 billion).

                 In the  states to be served by the  Interstate  Energy  system,
several public utilities are larger than Interstate  Energy's utility operations
will be following the  Transaction.  Union Electric  Company has total assets of
approximately $6.625 billion,  revenues of $2.117 billion,  electricity sales of
39.688 million MWH and 1.116 million  customers.  Northern  States Power Company
has total assets of  approximately  $5.950 billion,  revenues of $2.034 billion,
electricity sales of 39.829 million MWH and 1.389 million  customers.  Wisconsin
Energy  Company has total  assets of $4.408  billion,  total  revenues of $1.389
billion, electricity sales of 26.911 million MWH and 937,968 customers.

                 As the  following  table  demonstrates,  nine of the  currently
registered  electric  utility holding company systems are larger than Interstate
Energy will be following the Transaction in terms of assets, operating revenues,
customers and/or sales of electricity:

</TABLE>

                  In  addition,  Interstate  Energy  will  be  smaller  than the
registered  holding  companies  to be formed as a result of  recently announced
proposed and completed mergers,  specifically the mergers of AEP and CSW
(combined 1995 year-end assets of approximately $52.845 billion and operating
revenues of $9.172 billion), the Ameren combination of Union  Electric Company
and CIPSCO, Inc. (combined 1994 year-end assets of approximately  $8.402 billion
and operating revenues of $2.850 billion) and the New Centuries combination of
Public Service Company of Colorado and Southwestern  Public Service Company
(combined 1994 year-end assets of approximately $6.018 billion and operating
revenues of $2.881 billion.)

         Interstate  Energy  will be a small-  to  mid-size  registered  holding
company,  and its operations  would not exceed the economies of scale of current
electric  generation  and  transmission  technology  or provide  undue  power or
control to Interstate Energy in the region in which it will provide service.

         Efficiencies  and  economies:  The Commission has rejected a mechanical
size  analysis  under  Section  10(b)(1) in favor of  assessing  the size of the
resulting  system with reference to the  efficiencies  and economies that can be
achieved  through  the  integration  and  coordination  of  utility  operations.
American Electric Power Co., 46 S.E.C. 1299, 1309. More recent pronouncements of
the Commission confirm that size is not determinative. Thus, in Centerior Energy
Corp., Holding Co. Act Release No. 24073 (April 29, 1986), the Commission stated
flatly that a "determination  of whether to prohibit  enlargement of a system by
acquisition  is to be made on the  basis  of all the  circumstances,  not on the
basis of size alone." See also Entergy Corporation,  Holding Co. Act Release No.
25952  (December 17, 1993).  In addition,  the Division  recommended in the 1995
Report that the  Commission  approach  its  analysis  of merger and  acquisition
transactions  in a flexible  manner with  emphasis  on whether  the  Transaction
creates  an  entity  subject  to  effective  regulation  and is  beneficial  for
shareholders  and  customers  as  opposed  to  focusing  on  rigid,   mechanical
tests.(14)

         By virtue of the Transaction,  Interstate  Energy will be in a position
to realize  the  "opportunities  for  economies  of scale,  the  elimination  of
duplicate  facilities  and  activities,  the sharing of production  capacity and
reserves and generally more efficient operations" described by the Commission in
American  Electric  Power  Co.,  46 S.E.C.  at 1309.  Among  other  things,  the
Transaction  is expected  to yield  significant  production  cost  savings  from
integrated  economic  dispatch;  savings through greater purchasing power; labor
cost savings;  savings  through  consolidation  of corporate and  administrative
programs;  and savings from  integrated gas operations  through  optimization of
transportation capacity,  shortening storage withdrawal periods and avoidance of
duplicative reserve margins.  These expected economies and efficiencies from the
combined  utility  operations are described in greater detail in Item 3.A.2.b.i.
below and are projected to result in net savings of  approximately  $749 million
over the first ten years alone.

     Competitive  Effects:  As the Commission noted in Northeast  Utilities,
Holding Co. Act Release No. 25221 (Dec. 21, 1990), the "antitrust  ramifications
of an acquisition  must be considered in light of the fact that public utilities
are  regulated  monopolies  and that federal and state  administrative  agencies
regulate the rates charged  consumers." It is a condition to the consummation of
the Transaction that the applicable waiting periods under the HSR Act shall have
expired  or been  terminated.  On  June  7,  1996,  WPLH,  IES  and IPC  filed a
Notification  and  Report  Form  with  the DOJ and FTC  pursuant  to the HSR Act
describing the effects of the Transaction on competition in the relevant market.
The 30-day  waiting  period with  respect to such  Notification  and Report Form
expired  on July 7,  1996  without  the  issuance  of a request  for  additional
information from the DOJ or FTC. After the expiration of one year from the
original expiration, a subsequent filing in September of 1997 produced a similar
result. No further requirements consequently remain to be satisfied under the
HSR Act for the consummation of the Transaction.

     In addition,  the competitive  impact of the Transaction  was fully
considered  by  the  FERC  before  it  approved  the  Transaction.   A  detailed
explanation of the reasons why the Transaction will not threaten  competition in
even the most narrowly drawn  geographic and product markets is set forth in the
prepared testimony of Rodney Frame, filed with the FERC





                                       50
<PAGE>   55
     on behalf of WPLH, IES and IPC, a copy of which is filed as Exhibit K-1.
The application filed by WPLH, IES and IPC with the FERC is filed as Exhibit K-2
and the Order received is filed as Exhibit N-3. The Commission may
appropriately rely upon the FERC with respect to such matters. Entergy
Corporation, supra citing, City of Holyoke Gas & Electric Department et al. v.
S.E.C., 972 F.2d 358, 363-64 quoting Wisconsin Environmental Decade, Inc. v.
S.E.C., 882 F.2d 523, 527 (D.C. Cir. 1989).

         For these reasons, the Transaction will not "tend toward interlocking
relations or the concentration of control" of public utility companies, of a
kind or to the extent detrimental to the public interest or the interests of
investors or customers within the meaning of Section 10(b)(1).

   b. Section 10(b)(2)

         As noted above, Section 10(b)(2) requires the Commission to determine
whether the consideration to be paid in connection with the combination of WPLH,
IES and IPC, including all fees, commissions and other remunerations, is
reasonable and whether it bears a fair relation to investment in and earning
capacity of the utility assets underlying the securities being acquired.(15)

   i. Fairness of Consideration

         For the reasons set forth below, the requirements of Section 10(b)(2)
regarding consideration are satisfied in this Transaction.

         First, the Transaction is a pure stock-for-stock exchange and qualifies
for treatment as a pooling of interests for accounting purposes. As set forth
more fully above, each share of IES Common Stock will be converted into the
right to receive 1.14 shares of Interstate Energy Common Stock, each share of
IPC Common Stock will be converted into the right to receive 1.11 shares of
Interstate Energy Common Stock and each share of WPLH Common Stock will continue
as one share of Interstate Energy Common Stock. Each share of IPC Preferred
Stock and Utilities  Preferred  Stock  will remain  unchanged  unless  the
Reincorporation Mergers are effected, in which case it is anticipated that all
of the Utilities Preferred Stock will be redeemed by Utilities prior to
consummation of the Utilities Reincorporation Merger and each share of IPC
Preferred Stock (other than IPC Dissenting Shares) will be converted into one
share of New IPC Preferred Stock with terms and designations substantially
identical to those of the IPC Preferred Stock. The Transaction will,  therefore,
involve no "acquisition adjustment" or other write-up of the assets of WPLH, IES
or IPC.


         Second, the exchange ratios are the product of extensive and vigorous
arms-length negotiations between WPLH, IES and IPC. These negotiations were
preceded by extensive due diligence, analysis and evaluation of the assets,
liabilities and business prospects of each of the respective companies. See
"Background of the Mergers" at pages 31 to 45 of the WPLH Registration Statement
on Form S-4 (Exhibit I-1 hereto). As recognized by the Commission in Ohio Power
Co., 44 S.E.C. 340, 346 (1970),  prices arrived at through arms-length
negotiations are particularly persuasive evidence that Section 10(b)(2) is
satisfied.





                                       51
<PAGE>   56

        Finally,  nationally-recognized investment bankers for each of WPLH, IES
and IPC  have  reviewed  extensive  information  concerning  the  companies  and
analyzed the exchange ratios employing a variety of valuation methodologies, and
have opined that the exchange  ratios are fair,  from a financial point of view,
to the respective  holders of WPLH Common Stock, IES Common Stock and IPC Common
Stock.  The investment  bankers'  opinions are attached as Annexes L, M and N to
WPLH's Registration Statement on Form S-4 and are described on pages 53 to 69 of
the Form S-4 (Exhibit I-1 hereto). The assistance of independent  consultants in
setting consideration has been recognized by the Commission as evidence that the
requirements  of  Section  10(b)(2)  have been met.  The  Southern  Company;  SV
Ventures, Inc., Holding Co. Act Release 24579 (February 12, 1988).

         ii.     Reasonableness of Fees

         WPLH,  IES and IPC  believe  that the  overall  fees,  commissions  and
expenses  incurred and to be incurred in  connection  with the  Transaction  are
reasonable  and fair in light of the  size  and  complexity  of the  Transaction
relative to other  transactions and the anticipated  benefits of the Transaction
to the public,  investors and consumers;  that they are  consistent  with recent
precedent; and that they meet the standards of Section 10(b)(2).

         As set forth in Item 2 of this Application/Declaration, WPLH, IES and
IPC together expect to incur a combined total of approximately $14 million(16)
in fees, commissions and expenses in connection with the Transaction.  By
contrast, Cincinnati Gas & Electric Company and PSI Resources incurred $47.1
million in fees, commissions and expenses in connection with their
reorganization as subsidiaries of CINergy, Northeast Utilities alone incurred
$46.5 million in fees, commissions and expenses in connection with its
acquisition of Public Service Company of New Hampshire and Entergy alone
incurred approximately $38 million in fees, commissions and expenses in
connection with its recent acquisition of Gulf States Utilities -- all of which
amounts were approved as reasonable by the Commission.  See CINergy, Holding
Co., Act Release No. 26146 (Oct. 21, 1994); Northeast Utilities, Holding Co. Act
Release No. 25548 (June 3, 1992); Entergy Corp., Holding Co. Act Release No.
25952 (Dec. 17, 1993).

         With respect to financial advisory fees, WPLH, IES and IPC believe that
the fees payable to their investment bankers are fair and reasonable for similar
reasons. Pursuant to the terms of an engagement letter dated June 29, 1995, WPLH
has agreed to pay Merrill Lynch (i) a $100,000  retainer fee,  payable as of the
date of the engagement  letter,  (ii) $200,000 payable upon the execution of the
Merger  Agreement,  (iii) $200,000 payable upon the delivery by Merrill Lynch of
its fairness  opinion and (iv) a transaction fee payable only upon  consummation
of the Mergers equal to 0.40% of the product of the closing price of WPLH Common
Stock on  November  6,  1995,  which was  $30.75,  multiplied  by the sum of (a)
10,616,359, the number of outstanding shares of IPC Common Stock as set forth in
the Merger Agreement multiplied by the IPC Ratio, and (b) 29,639,029, the number
of outstanding  shares of IES Common Stock as set forth in the Merger  Agreement
multiplied  by the IES  Ratio  (approximately  $4,951,413),  against  which  the
amounts referred to in clauses (i) - (iii) above will be credited. WPLH has also
agreed to reimburse  Merrill Lynch for its  reasonable  out-of-pocket  expenses,
including all reasonable  fees and  disbursements  of its legal counsel,  and to
indemnify Merrill Lynch and





                                       52
<PAGE>   57

certain  related  persons  against  certain  liabilities in connection  with its
engagement, including certain liabilities under the federal securities laws.

         Pursuant  to a letter  agreement  dated June 30,  1995  between IES and
Morgan  Stanley,  Morgan Stanley is entitled to (i) an advisory fee for its time
and efforts  expended in connection with the engagement which is estimated to be
between $100,000 and $250,000,  which is payable in the event the transaction is
not consummated,  (ii) an announcement  fee of $1,000,000,  which has been paid,
and (iii) a transaction fee equal to the product of 0.472562%  multiplied by the
Aggregate  Value of the  transaction  (as such term is  defined  in such  letter
agreement), or approximately $4,370,228, which is payable only upon consummation
of the transaction. Any amounts paid or payable to Morgan Stanley as advisory or
announcement  fees will be credited  against the transaction fee. IES has agreed
to reimburse  Morgan  Stanley for its expenses,  including  reasonable  fees and
expenses of its counsel,  and to  indemnify  Morgan  Stanley and its  affiliates
against certain  liabilities and expenses,  including  liabilities under federal
securities laws.

         Pursuant to a letter  agreement dated  September 13, 1995,  between IPC
and Salomon Brothers, Salomon Brothers agreed to act as financial advisor to IPC
in  connection  with the Mergers.  IPC is  obligated  to pay Salomon  Brothers a
monthly fee of $25,000  during the term of the  engagement and an additional fee
equal to the product of 0.75% multiplied by the aggregate consideration paid for
IPC's common  equity  (approximately  $2,448,000).  This  additional  fee is due
Salomon Brothers as follows: 25% contingent upon and payable following execution
of the Merger Agreement;  25% contingent upon and payable following  approval by
the IPC stockholders;  and the remainder (less all monthly fees paid or payable)
contingent upon and only payable following consummation of the Mergers. IPC also
agreed to reimburse Salomon Brothers for its reasonable  out-of-pocket expenses,
including fees and  disbursements of counsel,  and to indemnify Salomon Brothers
and its affiliates,  their respective directors,  officers, agents and employees
and each person, if any,  controlling  Salomon Brothers or any of its affiliates
against certain liabilities,  including liabilities under the federal securities
laws, relating to, or arising out of, its engagement.

         c.      Section 10(b)(3)

         Section  10(b)(3)  requires the  Commission  to  determine  whether the
Transaction will unduly complicate Interstate Energy's capital structure or will
be detrimental to the public  interest,  the interests of investors or consumers
or the proper functioning of Interstate Energy's system.

         Capital structure:  The corporate capital structure of Interstate
Energy after the Transaction will not be unduly complicated and will be
substantially similar to capital structures of existing registered holding
company systems approved by the Commission in other orders.  See, e.g.,
CINergy, Holding Co. Act Release No. 26146 (Oct. 21, 1994); Centerior Energy
Corp., Holding Co. Act Release No. 24073 (April 29, 1986); Midwest Resources,
et al., Holding Co. Act Release No. 25159 (Sept. 26, 1990); Entergy Corp.,
Holding Co. Act Release No. 25952 (Dec. 17, 1993); Northeast Utilities, Holding
Co. Act Release No. 25548 (June 3, 1992).





                                       53
<PAGE>   58

         In the Transaction, the common shareholders of IES and IPC will receive
Interstate  Energy  Common Stock in exchange for their share of IES Common Stock
and IPC  Common  Stock,  respectively.  Interstate  Energy  will own 100% of the
common  stock of WP&L,  Utilities  (or New  Utilities)  and IPC (or New IPC) and
there will be no minority  common stock  interest  remaining in any of the three
companies.  Each share of IPC  Preferred  Stock  outstanding  at the time of the
consummation of the Transaction  (other than IPC Dissenting  Shares) will remain
outstanding preferred stock of IPC. However, if the Reincorporation  Mergers are
effected  as  described  more  fully  in  Item  1.A.2  above,  it  is  currently
anticipated that the shares of Utilities  preferred stock currently  outstanding
will  be  redeemed  by  Utilities   prior  to   consummation  of  the  Utilities
Reincorporation   Merger  and  each  share  of  IPC  preferred  stock  currently
outstanding  will be converted into one share of preferred stock of New IPC with
terms  (including  dividend  rates)  substantially  identical  to those of IPC's
preferred stock under IPC's Restated  Certificate of Incorporation  (Exhibit F-2
hereto).

         The debt securities of Utilities,  IPC and WP&L outstanding at the time
of the consummation of the Transaction will likewise remain outstanding  without
change except that,  if the  Reincorporation  Mergers are effected,  the debt of
Utilities  and  IPC  will  become  the  debt  of  New  Utilities  and  New  IPC,
respectively.

         The only voting  securities of Interstate Energy which will be publicly
held after the transaction will be Interstate  Energy Common Stock. With respect
to the direct non-utility subsidiaries of Interstate Energy and Interstate Hold,
the only class of voting  securities of such  subsidiaries will be common stock,
and  Interstate  Energy  or  Interstate  Hold will  hold all of the  issued  and
outstanding  shares of such common stock other than a minority  interest in HEHC
owned by certain employees as described in Item 1.B.5.a above.

         Set forth below are summaries of the  historical  capital  structure of
WPLH, IES and IPC as of December 31, 1995 and the pro forma consolidated capital
structure  of  Interstate  Energy  (assuming  the  Transaction  had  occurred at
December 31, 1995):

</TABLE>

Interstate Energy's pro forma consolidated common equity to total capitalization
ratio of 46.9% is significantly  higher than the common equity position approved
by the  Commission  for  Northeast  Utilities  (27.6%) and  CINergy  (39.5%) and
comfortably   exceeds  the  "traditionally   acceptable  30%  level."  Northeast
Utilities, Holding Co. Act Release 25221 (December 21, 1990).

         Protected  interests:  As  set  forth  more  fully  in  Item  3.A.2.b.i
(Efficiencies and Economies), Item 3.A.2.b.ii (Integrated Public Utility System)
and elsewhere in this Application/  Declaration,  the Transaction is expected to
result in substantial,  otherwise unavailable,  cost savings and benefits to the
public and to consumers and investors of WPLH,  IES and IPC, and will  integrate
and improve the efficiency of the WPLH, IES and IPC utility  systems.  Moreover,
as noted by the Commission in Entergy Corporation, Holding Co. Act Release 25952
(December 17, 1993),  "concerns  with respect to investors'  interests have been
largely addressed by developments in federal  securities laws and the securities
market  themselves."  WP&L,  Utilities  and IPC (or New IPC)  will be  reporting
companies  subject to the continuous  disclosure  requirements of the Securities
Exchange Act of 1934 (the "1934 Act") following  completion of the  Transaction.
The various  reports  previously  filed by WPLH,  IES and IPC under the 1934 Act
contain  readily   available   information   concerning  the  Transaction.   The
Transaction  will,  therefore,  be in the public  interest and the  interests of
investors and consumers,  and will not be detrimental to the proper  functioning
of the resulting holding company system.

         2.      Section 10(c)

         Section 10(c) of the Act provides that,  notwithstanding the provisions
of Section 10(b), the Commission shall not approve:

         (1) an  acquisition  of securities or utility  assets,  or of any other
         interest,  which is unlawful  under the  provisions  of Section 8 or is
         detrimental to the carrying out of the provisions of Section 11; (17)
         or

         (2) the acquisition of securities or utility assets of a public utility
         or holding  company unless the Commission  finds that such  acquisition
         will serve the public interest by tending





                                       55
<PAGE>   60

towards the economical and the efficient development of an integrated   public
utility system . . . .
         a.      Section 10(c)(1)

         Section  10(c)(1)  requires that an acquisition be lawful under Section
8. Section 8 prohibits  registered  holding  companies  from  acquiring,  owning
interests  in  or  operating  both  a  gas  and  an  electric   utility  serving
substantially  the  same  area  if  prohibited  by  state  law.   Following  the
Transaction, the utility subsidiaries of Interstate Energy will provide electric
and gas services in Wisconsin,  Illinois,  Iowa and Minnesota.  Since Wisconsin,
Iowa,  Illinois  and  Minnesota  laws all permit  combination  gas and  electric
utilities  serving the same area, the Transaction does not raise any issue under
Section 8 or, accordingly, the first clause of Section 10(c)(1). Indeed, Section
8 indicates  that a  registered  holding  company may own both gas and  electric
utilities where, as here, the relevant state utility commissions support such an
arrangement.

         Section 10(c)(1) also requires that  transactions not be detrimental to
carrying out the provisions of Section 11. Section 11(a) of the Act requires the
Commission to examine the corporate structure of registered holding companies to
ensure that unnecessary complexities are eliminated and voting powers are fairly
and equitably distributed.  As described above in Item 3.A.1.c., the Transaction
will not result in unnecessary complexities or unfair voting powers.

         Although  Section  11(b)(1)  generally  requires a  registered  holding
company system to limit its operations  "to a single  integrated  public utility
system,  and  to  such  other  businesses  as  are  reasonably  incidental,   or
economically  necessary or  appropriate  to the  operations  of such  integrated
public utility system," a combination  integrated gas and electric system within
a registered  holding  company is  permissible  under  Section 8.  Additionally,
Section 11(b)(1) provides that "one or more additional integrated public utility
systems" may be retained if, as here, certain criteria are met. Section 11(b)(2)
directs the  Commission  "to ensure that the  corporate  structure  or continued
existence  of any  company  in the  holding  company  system  does not unduly or
unnecessarily  complicate the structure,  or unfairly or inequitably  distribute
voting power among security holders, of such holding company system."

         As detailed  below,  the  Transaction  will not be  detrimental  to the
carrying out of the provisions of Section 11.

         i.      Retention of Gas Operations

         WP&L and South Beloit have provided retail gas distribution service for
more than 68 years.  Initially,  this service provided gas that was derived from
coal through local  manufactured gas or "town gas" plants.  From the late 1930's
to the early 1980's, interstate natural gas pipelines (primarily by ANR Pipeline
Company)  were   constructed  to  provide  natural  gas  delivery  to  WP&L  gas
distribution systems in each significant city served by WP&L and South Beloit.

         WP&L and South  Beloit also  responded  to FERC's  efforts from 1983 to
1993 to restructure the interstate  pipeline  industry.  In 1987, WP&L and South
Beloit were among the





                                       56
<PAGE>   61

first  LDCs  in  the  United  States  to  convert  from  firm   pipeline   "full
requirements"  sales service to firm  transportation-only  service in accordance
with open access  provisions  of FERC Order 436. In 1986,  WP&L and South Beloit
began  offering "open access"  retail  transportation  service to eligible large
customers.

         WP&L and South Beloit currently  purchase  transportation  service from
five United States pipeline carriers and storage from three underground  storage
service  providers.  WP&L and South Beloit  procure  natural gas  supplies  from
numerous suppliers located in North America. As a result of this "grid" approach
to gas supply acquisition, WP&L and South Beloit have retail gas rates which are
among the lowest in the region and well below the  national  average.  Moreover,
the diversity of supply and delivery  routes  provide for increased  reliability
for firm  customers.  Approximately  30% of the gas  delivered by WP&L and South
Beloit  is  third  party  gas  purchased  directly  by large  industrial  retail
customers.  Under rate designs approved by the various regulatory agencies, WP&L
and South Beloit are  financially  indifferent  to whether a customer  purchases
sales or transportation only service.

         Utilities and its  predecessor  companies  have provided gas service to
customers  throughout  Iowa  since the late  1940s.  Prior  thereto,  Utilities'
predecessor  companies  provided  manufactured  gas to their customers from coal
gasification  facilities  operated  by  such  predecessor  companies.  Utilities
historically grew by purchasing municipal gas systems and other utilities.

         Utilities  also  responded  to  FERC's  efforts  in the mid  1980's  to
restructure the interstate  pipeline industry.  In 1985,  Utilities offered open
access  transportation to eligible customers on its distribution  system. At the
same  time,  Utilities  began  purchasing  a  portion  of its  natural  gas from
suppliers  other than the  pipeline  companies  which  supplied gas and used the
pipelines for transportation only. Utilities currently purchases  transportation
services  on  three  interstate   pipelines  and  storage  services  from  three
pipelines.  Natural gas is procured from a number of different suppliers located
in the mid-continent, Gulf Coast and Canadian production areas.

         Utilities  continues to offer  competitively  priced  natural gas sales
service  to  customers  who  prefer  delivered  gas  service.  It also  provides
transportation  and balancing  services to a number of commercial and industrial
customers  who  prefer  to  purchase  their own gas and  transport  their gas on
pipelines   and  through  the   Utilities   distribution   system.   Under  this
transportation  service,  approximately 27% of all gas delivered by Utilities is
third party gas owned by customers.  Under rate designs  approved by the various
regulatory agencies,  Utilities is financially indifferent to whether a customer
purchases sales or transportation only service.

         IPC  and  its  predecessor  companies  have  provided  gas  service  to
customers in Iowa,  Minnesota  and  Illinois  since its  incorporation  in 1925.
Initially,  IPC and its predecessor companies provided manufactured gas to their
customers from coal gasification facilities.  Since 1951, all of IPC's gas sales
have predominantly been natural gas.

         IPC also  responded to FERC's  efforts in the mid 1980's to restructure
the   interstate   pipeline   industry.   In  1986,   IPC  offered  open  access
transportation  to eligible  customers on its distribution  system.  At the same
time, IPC began purchasing a portion of its





                                       57
<PAGE>   62

natural gas from suppliers other than the pipeline  companies which supplied gas
and  used  the  pipelines  for  transportation  only.  IPC  currently  purchases
transportation  services on two interstate  pipelines and storage  services from
two pipelines. IPC also contracts for synthetic storage services, which act like
a financial  hedge,  from one company.  Natural gas is procured from a number of
different  suppliers  located in the Gulf  Coast,  Canadian  and  Texas/Oklahoma
production  areas.  The  propane-air LPG peak shaving plants continue to provide
gas service to customers on the coldest days of the year while reducing pipeline
demand charges.

         IPC continues to offer  competitively  priced natural gas sales service
to customers who prefer delivered gas service.  It also provides  transportation
and balancing  services to a number of commercial and  industrial  customers who
prefer to  purchase  their own gas and  transport  their  gas on  pipelines  and
through IPC's distribution system. Under this transportation  service,  over 70%
of all gas  delivered by IPC is third party gas owned by  customers.  Under rate
designs  approved  by  the  various  regulatory  agencies,  IPC  is  financially
indifferent  to  whether  a  customer  purchases  sales or  transportation  only
service.

I.B.2.c.iv. above.

         Currently,  WPLH and IES are energy  service  companies  which are also
exempt holding companies,  and IPC is a public-utility company primarily engaged
in the energy services  business.  Following  consummation  of the  Transaction,
WP&L,  Utilities  and IPC will  continue to be energy services  companies.  In
today's  changing energy markets,  consumers and regulators must be -- and are
- -- more careful with limited energy resources than was ever  contemplated in
1935.  Increasingly,  customers select among different forms  of  energy  to
perform  the  same  or  similar  tasks   depending   upon environmental and
economic factors. As energy service companies, WP&L, Utilities and IPC offer,
and the  Interstate  Energy system will offer,  diverse forms of energy to
customers,  thereby  allowing choices among different forms of energy, which, in
turn, fosters efficiency and conservation.  By providing such choices, energy
companies assist in the allocation of scarce national  resources,  under the
supervision of local  regulators who are most familiar with the needs of the
local  constituencies.  This modern energy business,  with a high level of state
scrutiny,  is a far cry from the marketplace and regulatory  situation perceived
by the  drafters  of the Act and  the  then-perceived  abuses  that  arose  from
combination companies. The fears expressed at that time, the "favoring of one of
these competing forms of energy over the other," S.E.C. v. New England  Electric
System, 384 U.S. 176, 183 (1966), are no longer realistic in today's market.

For the  reasons  set forth  below and in the  accompanying  memoranda attached
as Exhibits L-1,  L-2, L-3, L-4, L-5 and L-6, Interstate Energy's retention of
the gas operations of WP&L  (including  South  Beloit),  Utilities  and IPC
should be  approved by the Commission.  Retention of such gas operations is
lawful under, and is consistent with the  congressional  intent  behind,
Section  8 of the Act and would not be detrimental to the carrying out of
Section 11 of the Act.


         Section 8: Section 8 of the Act provides  that  "[w]henever a State law
prohibits,  or requires approval or authorization of, the ownership or operation
by a single company of the utility assets of an electric  utility  company and a
gas  utility  company  serving  substantially  the same  territory,  it shall be
unlawful for a registered holding company, or any subsidiary company





                                       58
<PAGE>   63

thereof . . . (1) to take any step, without the express approval of the state
commission of such state, which results in its having a direct or indirect
interest in an electric utility company and a gas company serving substantially
the same territory; or (2) if it already has any such interest, to acquire,
without the express approval of the state commission, any direct or indirect
interest in an electric utility company or gas utility company serving
substantially the same territory as that served by such companies in which it
already has an interest."  (emphasis added)

         On its  face,  Section  8  indicates  that,  with the  approval  of the
relevant  state utility  commissions,  registered  holding  company  systems can
include both electric and gas utility systems.  A careful reading of the section
indicates  that  the  thrust  of  the  section  is to  preclude  the  use of the
registered  holding company form to circumvent any state law restrictions on the
ownership  of gas and electric  assets by the same  company.  Thus,  combination
registered  holding  companies,  or a  registered  holding  company  system that
includes  combination  companies,  are implicitly  acceptable  under the statute
absent an objection by the affected state(s).

         WPLH,  IES and IPC believe it is  consistent  with both the Act and its
policy objectives to permit combination  companies to exist and operate provided
such combination  companies are permitted by the affected states.  Indeed,  over
time the  Commission  has  emphasized  different  aspects  of  Section 8 and its
interplay with Section 11 -- initially allowing  registered holding companies to
own both gas and electric  systems  under Section 8, then focusing on Section 11
as controlling determinations regarding combination companies, and requiring the
second system to meet a strict  interpretation  of the requirements set forth in
clauses A, B and C of Section 11(b)(1) which is discussed below.

         While the  Commission  has  focused on Section 11 and  adopted a narrow
interpretation of the standards contained therein as the controlling factor with
regard to combination  registered  holding companies since the early 1940s, both
the  legislative  history of the Act and recent changes in the utility  industry
indicate  that  it is now  appropriate  and  necessary  for  the  Commission  to
reemphasize  the  provisions  of  Section  8 of the  Act and  allow  combination
registered  holding companies where they are permitted under relevant state law,
as they are in this case.(18)

         The  legislative  history of  Section 8  supports a policy of  allowing
combination  utilities  where they are  permitted  by state law. As noted in the
Senate Interstate  Commerce Committee "[Section 8] is concerned with competition
in the field of  distribution  of gas and  electric  energy -- a field  which is
essentially  a question of State policy,  but which becomes a proper  subject of
Federal  action  where the  extra-State  device of a holding  company is used to
circumvent  state policy." S. Rep. No. 2796,  74th Cong.,  1st Sess., pt 1 at 31
(1935) (the "Senate  Report").  Nothing in the legislative  history  indicates a
Congressional desire to prohibit combination companies where state approvals can
be obtained.

         Much more recently, the Division noted in the 1995 Report, "it does not
appear that the SEC's precedent concerning  additional systems precludes the SEC
from relaxing its  interpretation of Section  11(b)(1)(A)" and "that the utility
industry is evolving  toward the creation of one-source  energy  companies  that
will provide  their  customers  with  whatever  type of energy supply they want,
whether  electricity  or gas."  The  Division  recommended  that the  Commission
interpret  Section 11(b)(1) of the Act to allow registered  holding companies to
hold





                                       59
<PAGE>   64
both  gas  and  electric  operations  as long as  each  affected  state  utility
regulatory commission approves of the existence of such a company.(19)

         Local regulators are in the best position to assess the needs of their
communities.  The Act was never intended to supplant local regulation but,
rather, was intended to create conditions under which local regulation was
possible.  Section 21 of the Act, which further codifies this legislative
intent, states:  "Nothing in [the Act] shall affect . . . the jurisdiction of
any other commission, board, agency, or officer of . . . any State, or
political subdivision of any State, over any person, security, or contract,
insofar as such jurisdiction does not conflict with any provision of [the Act]
 . . . ."

         The legislative  history reveals that Section 21 of the Act was further
intended "to insure the autonomy of state commissions [and] nothing in the [Act]
shall exempt any public  utility from  obedience  to the  requirements  of state
regulatory  law." Senate Report at p. 10. Thus,  the Act should not be used as a
tool to override state policy, particularly when the holding company involved is
subject  to both  state  and  federal  regulation  and when the  affected  state
regulatory  commissions have supported  combined  electric and gas operations in
one holding company system.

         Finally,  this  analysis  and focus fits within the overall  regulatory
scheme of the Act. First,  Section 11 of the Act is flexible and was designed to
change as the policy concerns over the regulation of utility  holding  companies
changed.(20) As discussed  below,  the utility industry and the regulation of
that industry has changed  dramatically in recent years. Second, a registered
holding company  would  still  be  required  to  demonstrate  that  any
acquisition  or transaction  by  which  it  would  become a  combination
company  would  not be detrimental  to the carrying out of the  provisions of
Section 11 of the Act. In other words, its electric system would have to
constitute an integrated electric system and its gas system would have to
constitute an integrated  gas system and both systems must be capable of being
operated efficiently.  Thus, the standards of Section 11 would still have to be
met, but the application of those standards should  take into  account  the
fundamental  policy of the Act and allow  local regulators  to make the
threshold  determination  with  regard  to  combination companies.

         Each of WP&L (including South Beloit), Utilities and IPC is permissible
as a combination  company  pursuant to the terms of Section 8 of the Act because
the affected  states are expected to approve the continued  combined  activities
and each is in the public  interest.  Moreover,  as  required by Section 11, the
electric  systems  of  WP&L,  South  Beloit,  Utilities  and IPC  constitute  an
integrated  electric system and the gas systems of each together will constitute
an integrated gas system as explained in detail below under Item 3.A.2.b.ii.

         Interstate Energy as a combination  company is permissible  pursuant to
the terms of  Section 8 of the Act and is in the  public  interest.  First,  the
combination  of electric and gas  operations in WP&L  (including  South Beloit),
Utilities  and IPC is  lawful  under  all  applicable  state  laws  and has been
considered  and tacitly  approved  on numerous  occasions  by  Wisconsin,  Iowa,
Minnesota and Illinois  regulators who have,  and will continue to have,  direct
jurisdiction over the Interstate Energy electric and gas operations.  Interstate
Energy will not be using its holding  company  structure to circumvent any state
regulations  since the gas utility  operations of WP&L, South Beloit,  Utilities
and IPC, respectively, will continue to be regulated by the





                                       60
<PAGE>   65

relevant state jurisdictions. In addition, in connection with their applications
for approval of the  Transaction  submitted or to be submitted to the Wisconsin,
Iowa,  Illinois  and  Minnesota  regulatory  commissions  -- who have,  and will
continue to have,  direct  jurisdiction  over the Interstate Energy system's gas
operations  located in their respective states -- WP&L, South Beloit,  Utilities
and IPC expect these  commissions to either order or express  approval for WP&L,
South  Beloit,  Utilities  and IPC to continue as  combination  electric and gas
utility  companies  through the retention of their respective gas operations and
for Interstate  Energy to operate as a holding  company for WP&L,  Utilities and
IPC.  Such  actions by the  applicable  state  commissions  will  reflect  their
recognition  that  the  existence  of  both  gas  and  electric  systems  in the
Interstate  Energy  holding  company  system  will  allow  Interstate   Energy's
customers  greater choice to meet their energy needs,  especially given the fact
that the electric and gas systems  operate in  substantially  the same territory
while sharing in the synergies that result from the Transaction.  Moreover,  the
prior fear that a holding  company  such as  Interstate  Energy would be able to
greatly  emphasize one form of energy over the other based on its own agenda has
dissipated  both because of the competitive  nature of the energy market,  which
requires  utilities to meet customer  demand for energy supply  requirements  or
risk losing the customer to a competing  supplier,  and because state regulators
will  have  sufficient  control  over,  and  would be  unlikely  to  approve,  a
combination company that attempts to undertake such practices.

         Furthermore,  the Commission has reviewed and approved the  combination
gas and  electric  operations  of WPLH  and IES in  several  prior  orders.  IES
Industries Inc., Holding Co. Act Release No. 25325 (June 3, 1991), (IES' Section
3(a)(2) exemption  continued by the Commission  virtually without  discussion in
connection  with the merger of two exempt  holding  companies  with  combination
electric and gas  utilities);  WPL Holdings,  Inc.,  Holding Co. Act Release No.
24590  (February  26,  1988) (the  Commission  reviewed  its prior  decisions on
ownership of electric and gas  utilities by exempt  holding  companies and noted
that the PSCW staff had  advised  the  Commission  "that it had  experienced  no
problems  regulating  combined  electric  and gas  companies  and was opposed to
separating such operations into separate companies");  Wisconsin Power and Light
Co., 1 S.E.C. 362 (1936).

         For all of the foregoing  reasons,  the  Commission  should approve the
retention  by  WP&L  (including  South  Beloit),  Utilities  and  IPC  of  their
respective gas properties as contemplated by the Transaction. No policy would be
furthered by requiring divestiture, and, in fact, state policy would be thwarted
by such a requirement.

         Section  11:  Even  if  the  Act  were  not  interpreted  as  generally
permitting combination gas and electric systems upon state approval,  Section 11
contains additional  provisions that permit the retention by WP&L, Utilities and
IPC of their  respective  gas  systems.  Section  11(b)(1)  of the Act permits a
registered  holding company to control one or more additional  integrated public
utility systems -- i.e., gas as well as electric -- if:

                 (A) each of such  additional  systems  cannot be operated as an
         independent system without the loss of substantial  economies which can
         be secured by the retention of control by such holding  company of such
         system;

                 (B)      all of such additional systems are located in one
         state, adjoining states, or a contiguous foreign country; and





                                       61
<PAGE>   66


                 (C) the continued combination of such systems under the control
         of such holding company is not so large  (considering  the state of the
         art and the area or region  affected)  as to impair the  advantages  of
         localized  management,  efficient  operation,  or the  effectiveness of
         regulation.

         Each of these requirements is satisfied in this Transaction.  Retention
is, therefore, appropriate on the basis of Section 11(b)(1).

         In the 1995  Report,  the  Division  recommended  that  the  Commission
"liberalize its  interpretation  of the `A-B-C'  clauses." (21) The Commission
has historically  given  consideration  to four  ratios as a "guide" to
determining whether lost economies are "substantial" under Section 11(b)(1)(A).
These ratios measure  the  projected  loss of  economies  as a  percentage  of:
(1) total gas operating revenues; (2) total gas expense or "operating revenue
deductions"; (3) gross gas income;  and (4) net gas income or net gas utility
operating  income. Although the Commission has declined to draw a bright-line
numerical test under Section  11(b)(1)(A),  it has indicated that cost increases
resulting in a 6.78% loss of operating revenues, a 9.72% increase in operating
revenue deductions,  a 25.44%  loss of gross  income and a 42.46%  loss of net
income  would  afford an "impressive basis for finding a loss of substantial
economies." Engineers Public Service Co., 12 S.E.C. 41, 59 (1942).

         In this case,  the lost  economies that would be experienced if the gas
properties of WP&L (including the gas properties owned by WP&L and South Beloit,
which are both part of a single  inter-connected gas system),  Utilities and IPC
were each to be operated on a stand-alone  basis exceed these  numbers,  without
any increase in benefits to consumers. These lost economies result from the need
to  replicate   services,   the  loss  of  economies  of  scale,  the  costs  of
reorganization,  and other factors, and are described more fully in the Analysis
of the Economic  Consequences  of Divestiture of Wisconsin Power and Light's and
South Beloit Water, Gas and Electric's  Natural Gas Operations,  Analysis of the
Economic  Impact of a Divestiture  of IES Utilities  Inc.'s Gas  Operations  and
Analysis of the Economic  Impact of a Divestiture of Interstate  Power Company's
Gas Operations  (collectively,  the "Gas Studies")  (attached as Exhibits L-2
and L-6  hereto).  In the  absence  of  rate  relief,  these  lost  economies
would substantially  injure the shareholders of WPLH, IES and IPC upon the
divestiture of those gas  operations.  As the Gas Studies  further show, if rate
relief were granted  with respect to the lost  economies,  then  consumers would
bear those substantial  costs  over  what they  would  have to pay if the
properties  were retained as contemplated by the Transaction.

         As set forth in the Gas Studies,  divestiture  of the gas operations of
WP&L,  Utilities  and  IPC  into  stand-alone  companies  would  result  in lost
economies of $15,558,000 for WP&L,  $14,205,142 for Utilities and $5,048,533 for
IPC. Exhibit L-6 considers the case of combining the gas properties of WP&L,
Utilities and IPC into one company prior to divestiture which would still
result in lost economies of approximately $27,000,000. The table below shows the
gas operating  revenues,  gas  operating  revenue deductions, gas gross income
and gas net income of WP&L, Utilities and IPC.

</TABLE>

         As a percentage of 1995 gas net income,  the lost  economies  amount to
144.62% in the case of WP&L,  145.66% in the case of Utilities and 87.06% in the
case of IPC. These percentage  losses in gas net income, as described in the Gas
Studies,  that will be  suffered  by the WP&L,  Utilities  and IPC gas  systems,
respectively,  if operated on a stand-alone  basis are far in excess of the loss
of net income in UNITIL  Corp.,  Holding Co. Act Release No.  25524,  (Apr.  24,
1992), where the Commission allowed the retention of the gas utility operations,
and the 30% loss in the New England Electric System case that the Commission has
described as the highest loss of net income in any past  divestiture  order.(22)
As a percentage of 1995 gas operating revenues, the lost economies described  in
the Gas Studies would equal  10.80%  in the  case of WP&L,  9.84% in the case of
Utilities  and  11.56%  in the  case of IPC,  which in each  case  substantially
exceeds  the  percentage  loss  in any  past  divestiture  order  issued  by the
Commission and exceeds the losses in UNITIL and Entergy Corporation, Holding Co.
Act Release No. 25952 (December 17, 1993),  another case in which the Commission
authorized the retention of gas operations.  As a percentage of 1995 expenses or
operating revenue  deductions,  the lost economies  described in the Gas Studies
would  equal  11.68% in the case of WP&L,  10.90% in the case of  Utilities  and
14.78%  in the  case of  IPC,  which  in each  case  substantially  exceeds  the
percentage loss in any past  divestiture  order issued by the Commission and the
losses in UNITIL and Entergy. As a percentage of 1995 gas gross income, the lost
economies  described  in the Gas  Studies  amount to 81.04% in the case of WP&L,
101.33% in the case of  Utilities  and 53.03% in the case of IPC,  which in each
case  exceeds the highest  loss of gross income in any  divestiture  order.  The
applicable percentages here and in past cases are summarized in Exhibit L-5.

         In order to recover  these lost  economies,  the WP&L gas system  would
need to  increase  its  revenue  from  rates by $14.024  million  or 9.74%,  the
Utilities  gas system  would need to increase  its revenue from rates by $14.205
million or 9.84% and the IPC gas system  would need to increase its revenue from
rates by $5,048,533  and 11.56%.  These  increases in rate revenues would have a
direct and immediate  negative  impact on the rates charged to consumers for gas
services.  In  addition,  the  customers  of the  WP&L,  Utilities  and  IPC gas
businesses  who  are  also  customers  of  their  respective   electric  utility
businesses will experience a doubling of their postage costs to pay two separate
monthly bills. The total estimated increase in such postage costs is $900,000 in
the aggregate for the gas customers of the three companies.

         Divestiture would also result in the loss to consumers of the economies
offered by the  "energy  services"  approach of WP&L,  Utilities  and IPC to the
utility business. While the losses cannot be fully quantified,  they are clearly
substantial.  For the  energy  services  company,  providing  gas  and  electric
products is only the start of the  utility's  job. The utility must also provide
enhanced service to the consumer by providing an entire package of both





                                       63
<PAGE>   68

energy products and services. In this regard, the efforts of WP&L, Utilities and
IPC  reflect a trend by  utilities  to  organize  themselves  as energy  service
companies  which provide a total package of energy  services  rather than merely
supplying gas and electric products. The goal of an energy service company is to
retain  its  current  customers  and  obtain new  customers  in an  increasingly
competitive environment by meeting customers' needs better than the competition.
An energy service company can provide the customer with a low cost energy (i.e.,
gas, electricity or conservation) option without inefficient subsidies.

         The energy services company  operating  combination  utilities offers a
wide range of benefits.  For customers,  an energy service company  provides the
convenience  and  efficiency of service by a single energy  provider and reduces
transaction  costs incurred in gathering and analyzing  information,  contacting
energy  suppliers,  negotiating  terms of  services  and paying  bills.  For the
communities  in which an energy  service  company  operates,  combining  gas and
electric operations simplifies community planning on energy-related matters. For
society,  an energy  service  company is best able to ensure an  environmentally
efficient  allocation of energy.  For utility  shareholders  and  employees,  an
energy  service  company is better able to respond to a competitive  environment
and to remain an  attractive  investment  opportunity  for  shareholders  and an
appealing employer for utility employees.

         The Commission has  historically  looked to the Supreme Court decisions
in S.E.C. v. New England Electric System, et al., 384 U.S. 176 (1966) ("NEES I")
and 390 U.S.  207  (1968)  ("NEES  II") in  interpreting  clause  (A) of Section
11(b)(1). In NEES I, the Supreme Court accepted the Commission's  interpretation
of the "loss of  substantial  economies"  language  of clause  (A) to require an
applicant  seeking to own an electric  and gas  utility  system to show that the
additional  system  would be  incapable  of  independent  economic  operation if
separated  from  the  principal  system.  The  Court  in  NEES  I  accepted  the
Commission's  then-current  interpretation  of clause (A),  despite  earlier SEC
interpretations permitting the Commission to use business judgment and expertise
to apply the statutory  phrase "loss of  substantial  economies." In NEES I, the
Court  specifically  recognized  that the language of clause (A) was "admittedly
not  crystal  clear"  and  deferred  to the  agency's  "expertise  on the  total
competitive  situation." 384 U.S. at 185 (emphasis in original). In NEES II, the
Court  reiterated  and  strengthened  its earlier  statement of deference to the
Commission. 390 U.S. at 219.

         The Division  recognized in the 1995 Report that the  Commission was no
longer  bound  by the  narrow  interpretation  of  clause  (A)  under  the  NEES
decisions. In so doing, the Division stated:

                 As discussed  above,  the SEC has generally  required  electric
                 registered  holding  companies  that  seek to own  gas  utility
                 properties  to satisfy the  requirements  of the A-B-C  clauses
                 concerning additional  integrated systems. In contrast,  exempt
                 holding  companies  have  generally been permitted to retain or
                 acquire  combination  systems so long as combined  ownership of
                 gas and  electric  operations  is permitted by state law and is
                 supported by the interested regulatory authorities.

<PAGE>   69

                 In the past,  the SEC has construed the A-B-C clauses  narrowly
                 to permit  retention  only  where  the  additional  system,  if
                 separated  from the  principal  system,  would be  incapable of
                 independent  economic  operations.  Although the Supreme  Court
                 upheld the SEC's reading,  two justices  dissented,  contending
                 that the  "serious  impairment"  standard  was at odds with the
                 wording of the Act, had little basis in the  statutory  history
                 or aims of the Act,  and  could not be  sustained  by agency or
                 judicial  precedent.  The dissenting justices believed that the
                 statutory  language  "called  for a business  judgment  of what
                 would be a significant loss."

                 Applicants in recent matters have argued that, in a competitive
                 utility   environment,   any  loss  of  economies  threatens  a
                 utility's  competitive  position,  and even a  "small"  loss of
                 economies  may  render  a  utility  vulnerable  to  significant
                 erosion of its competitive  position.  There is general support
                 for a more relaxed standard.  A number of commenters  emphasize
                 that these are  essentially  state  issues.  It does not appear
                 that  the  SEC's  precedent   concerning   additional   systems
                 precludes the SEC from relaxing its  interpretation  of section
                 11(b)(1)(A).  Indeed,  the SEC has  recognized  that section 11
                 does  not  impose  "rigid   concepts"  but  rather   creates  a
                 "flexible"  standard  designed "to  accommodate  changes in the
                 electric utility industry."

                 Congress,  in 1935, recognized that competition in the field of
                 distribution  of gas  and  electric  energy  is  essentially  a
                 question  of  state  policy.  The Act was  intended  to  ensure
                 compliance with state law in this regard.  Moreover, it appears
                 that the utility  industry is evolving  toward the  creation of
                 one-source  energy  companies that will provide their customers
                 with  whatever  type  of  energy  supply  they  want,   whether
                 electricity or gas.  Accordingly,  the Division  believes it is
                 appropriate to reconcile the treatment of registered and exempt
                 companies in this regard, and so recommends that the SEC permit
                 registered  holding  companies to own gas and electric  utility
                 systems  pursuant  to the A-B-C  clauses of  section  11(b)(1),
                 where the affected states agree.(23)

         In  NEES  I  (and  NEES  II),  the  Court  accepted  the   Commission's
interpretation of clause A as a "construction  well within the permissible range
given to those who are charged  with the task of giving an  intricate  statutory
scheme  practical sense and  application."  384 U.S. at 185.  However,  there is
strong  support in Supreme Court case law for the  Commission's  application  in
this  case of its  current  interpretation  of  clause  A,  based  upon  current
competitive  facts and current policy,  as stated in the 1995 Report. In Chevron
USA, Inc. v. National Resources Defense Council,  Inc., 467 U.S. 837 (1984), the
Court outlined the parameters for changing agency  interpretations  of statutory
language based on policy considerations and agency expertise:





                                       65
<PAGE>   70

                 When a court  reviews an agency's  construction  of the statute
                 which it  administers,  it is  confronted  with two  questions.
                 First,  always,  is the question  whether Congress has directly
                 spoken  to the  precise  question  at issue.  If the  intent of
                 Congress  is  clear,  that  is the end of the  matter;  for the
                 court,  as  well  as  the  agency,  must  give  effect  to  the
                 unambiguously  expressed intent of Congress.  If, however,  the
                 court  determines  Congress  has  not  directly  addressed  the
                 precise question at issue, the court does not simply impose its
                 own  construction on the statute,  as would be necessary in the
                 absence of an  administrative  interpretation.  Rather,  if the
                 statute is silent or  ambiguous  with  respect to the  specific
                 issue,  the  question  for the court is  whether  the  agency's
                 answer is based on a permissible construction of the statute.

467 U.S. at 842 (citations omitted;  emphasis added). Justice Scalia pointed out
that the Court's Chevron  opinion  "announced the principle that the courts will
accept an agency's reasonable interpretation of the ambiguous terms of a statute
that  the  agency   administers."   Antonin  Scalia,   "Judicial   Deference  to
Administrative Interpretations of Law," 1989 Duke L.J. 511.

         In the NEES I opinion,  the Supreme Court specifically pointed out that
"[t]he phrase  'without the loss of  substantial  economies'  is admittedly  not
crystal  clear." 384 U.S. at 185.  Thus,  the first prong of the analysis  under
Chevron is clearly met. As Justice Scalia pointed out, under Chevron:

                 "the  agency is free to give the statute  whichever  of several
                 possible meanings it thinks most conducive to accomplishment of
                 the statutory  purpose.  Under the latter  regime,  there is no
                 apparent  justification  for  holding  the  agency to its first
                 answer, or penalizing it for a change of mind."

1989 Duke L.J. at 516.  Justice Scalia argues that a primary point of Chevron is
to allow agencies  flexibility to change their statutory  interpretations  based
upon  current  economic  (and even  political)  considerations.  Under  Chevron,
therefore,  it is appropriate for the Commission to interpret  clause A based on
its current "expertise on the total competitive situation." (NEES I at 185.)

         Applicants believe that the Division's  recommendation  would represent
sound policy by the  Commission.  From a policy  perspective,  the  Commission's
historic  concern  underpinning  its 1964 NEES  decision  and a host of  earlier
decisions  where the  retainability  of gas  properties by  registered  electric
systems was at issue -- namely,  of fostering  competition  between electric and
gas -- is simply no longer  valid  given the  current  "state of the art" in the
electric and gas utility  industries.  In the  generation  since the  Commission
decided the NEES case,  profound  economic  and  regulatory  factors have caused
fundamental  changes in the gas supply and electric generation  industry.  These
changes  have made the  Commission's  earlier  positions  regarding  combination
utilities obsolete.





                                       66
<PAGE>   71
 In the gas area,  regulatory  changes have introduced  competition into what
was formerly a monopoly and have expanded the  availability  of non-utility
"transportation-only service" as an alternative of sales services from the local
gas utility company.  The WP&L,  Utilities and IPC gas operations all have "open
access"  transportation  service  tariffs  on file with their  respective  state
commissions,  and  approximately  47% of the gas  delivered  by them in 1995 was
directly  purchased by  customers.  Combination  utilities  therefore  have less
ability  than  they did in 1935 to  "favor"  electric  -- the  principal  policy
concern in decisions  ordering the separation of gas and electric  systems -- by
curtailing  the  availability  or  increasing  the price of  gas.(24)
Combination utilities  also have less  incentive to favor  electric over gas in
light of the increasing importance of demand-side management, the costs and
risks involved in the  construction  of new  generating  capacity and the
incentives to avoid such construction,  and the emergence of integrated
resource planning involving both gas and  electric  service  as noted in the
June 1994  issue of The  Electricity Journal.

         In the  electric  area,  the  Energy  Policy Act of 1992 and the Public
Utility  Regulatory  Policies Act of 1978 have introduced  competition  into the
electric  utility  business.  As the  chairman of the Senate  Banking  Committee
stated recently:

                 "[The Act] was  substantially  changed by the Energy Policy Act
                 of 1992. That law  restructured the utility industry to promote
                 greater  competition for the benefit of energy  customers.  The
                 Energy  Policy  Act of 1992 was the  product  of a  cooperative
                 effort  on the part of the  Banking  Committee  and the  Energy
                 Committee to create a more market-oriented regulatory framework
                 for the energy industry."

Hearing on S. 182, The Communications Act of 1994 before the Comm. on Commerce,
Science and Transportation, 103rd Cong. 2nd Sess. 344-345 (1994) (Prepared
Statement of Senator Riegle) (emphasis added).  In addition, many states have
"retail wheeling" measures under discussion which are likely to have the effect
of extending electric supply competition to the retail level.  Wisconsin, and
to a lesser extent Minnesota, are each in the process of evaluating various
options that could increase electric supply competition at the retail level.(25)

         Instead of relying on the blunt  instrument of competition  between gas
and electric,  national policy has now created direct competition within the gas
and electric utility industries.  Thus, combination ownership does not eliminate
competition,  since a combination  utility now has  competitors for both gas and
electric service. Moreover, competition is not an end in itself, but is merely a
means  to the  end  of  efficient,  cost-effective  service.  Since  combination
ownership  creates  efficiencies  and no longer  has the  effect of  eliminating
competition,  there is no reason  for the  Commission  to  prohibit  combination
ownership, at least under the circumstances presented here.

         Nothing in the Supreme Court's NEES decisions compels a different
result.  First, as the Commission noted in its Union Electric decision, the
Supreme Court's NEES decisions attached "great weight ... to [the Commission's]
expertise in the administration of the Act."  45 S.E.C. 489, 509, n.77. (1974).
The NEES decisions and the Court's reasoning in Chevron therefore leave the
Commission free to apply its expertise to administer the Act in light of





                                       67
<PAGE>   72

changes in legal, regulatory and economic circumstances which were not
foreseen at the time of the NEES decisions, including federal legislation which
has "substantially changed" the Act.  See Chevron, 476 U.S. at 842.

          Second,  as  noted  by the  Commission  in Union  Electric  and  later
decisions,  the NEES  decisions  are based on premises and policies  that are no
longer  operative.  See Delmarva Power & Light Co., et. al., 46 S.E.C.  710, 716
(1976)  ("the  objective  of  promoting  retail  competition   between  gas  and
electricity,  which was stressed in the NEES opinions,  is less critical now.");
Union Electric Co., 45 S.E.C. 489, 510 (1974), City of Cape Girardeau,  Missouri
v.  S.E.C.,  521 F.2d  324  (D.C.  Cir.  1974)  (describing  as  "outmoded"  the
Commissions'  previous  policy to "promot[e] the wider...use of gas and electric
energy" and to "foster...variegated  competition between gas and electricity and
the attendant  promotion of the use of each;" holding that "the  maximization of
energy use seems a questionable  public policy objective" and that "[i]n today's
world the public  interest and the long-run  consumer  interest seem to call for
prudent conservation and rational allocation" of resources).

         (B) and (C) clauses: The remaining requirements of Section 11(b)(1) are
met because the gas operations of WP&L (including  South Beloit),  Utilities and
IPC are located in adjoining states  (Wisconsin,  Illinois,  Iowa and Minnesota)
and because the combination of the gas operations under Interstate Energy is not
so large  (considering  the state of the art and the area or region affected) as
to impair the  advantages of localized  management,  efficient  operation or the
effectiveness of regulation.  The gas systems are confined to a relatively small
area and are not as large as other  gas  systems  in the  states  served  by the
applicants and will preserve the advantages of localized  management,  efficient
operation  and  effectiveness  of  regulation.  The  Commission  has  recognized
elsewhere that the  determinative  consideration is not size alone or size in an
absolute sense, either big or small, but size in relation to its effect, if any,
on localized  management,  efficient  operation and effective  regulation.  From
these  perspectives,  it is clear  that  the  continued  combination  of the gas
operations under Interstate Energy is not too large.  Following the Transaction,
the gas operations of WP&L, South Beloit,  Utilities and IPC, with approximately
370,000 customers in four states,  will be smaller than the following  companies
which  have  gas  operations  in such  states:  Minnegasco  (which  has  630,000
customers in Minnesota),  Northern Illinois Gas Company (1,769,800  customers in
Illinois),  Mid-American Energy (which has 467,547 customers in Iowa),  People's
Gas Light and Coke Company  (which has 842,510  customers in the Chicago  area),
Utilicorp  United (288,093  customers in Iowa and  Minnesota),  and the proposed
combination  of  Wisconsin  Electric  Power  Company and  Northern  States Power
Company  (750,000  customers  predominately  in Minnesota and Wisconsin).  These
companies all provide service in the same states as the applicants.

         With  respect  to   localized   management,   management   will  remain
geographically close to each of the three gas operations, thereby preserving the
advantages of localized management.  WP&L (and South Beloit),  Utilities and IPC
will be operated  as separate  subsidiaries  of  Interstate  Energy for at least
three years after the  consummation  of the  Transaction and will continue to be
headquartered  in Madison,  Wisconsin,  Cedar  Rapids,  Iowa and Dubuque,  Iowa,
respectively.  From  the  standpoint  of  regulatory  effectiveness,   each  gas
operation is organized as a separate corporation and will continue to be subject
to  regulation by the  respective  state in which such gas operation is located,
which will ensure the continued  effectiveness of state regulation.  IPC already
operates a multi-jurisdictional (Iowa, Illinois and





                                       68
<PAGE>   73
Minnesota) gas utility, as does WP&L directly and through its subsidiary,  South
Beloit (Wisconsin and Illinois). Several other gas utilities in the region serve
customers in multiple states.  Accordingly,  the regulating agencies in the four
state region currently regulate multi-  jurisdictional gas utilities and will be
able to effectively regulate the gas utility operations of Interstate Energy. In
addition,  it is expected that each relevant  state  regulatory  authority  will
indicate its support for or order the retention by Interstate  Energy of the gas
system(s)  located in such  state,  thereby  indicating  that  state  regulating
authorities  can  continue to  regulate  such system  effectively.  Finally,  as
detailed above, the gas operations of WP&L (including  South Beloit),  Utilities
and IPC enjoy  substantial  economies as part of the WPLH,  IES and IPC systems,
respectively,  and  will  realize  additional  economies  as  a  result  of  the
Transaction  as part of the  Interstate  Energy  system.  Far from impairing the
advantages  of  efficient  operation,  the  continued  combination  of  the  gas
operations under Interstate Energy will facilitate and enhance the efficiency of
gas operations.
         
         In recent months the Commission has been presented with several real,
rather than hypothetical, opportunities to assess the recommendations of the
Division made in the 1995 Report as to the appropriateness of combination
electric and gas companies under the Act as several companies seeking to
implement convergence mergers have filed applications with the Commission. At
the same time, merger opponents have sought to persuade the Commission that the
Commission should not implement the Division's recommendations.

         In July and August of 1997, the Commission approved three convergence
mergers clarifying that the Act does not prohibit combination electric and gas
companies of the type sought to be created in the instant situation.(26) In the
words of the Commission, the Act "does not prohibit ownership of combination gas
and electric systems." New Century Energies, Inc., Holding Co. Act Release No.
26748 at 27.

                  The Commission's actions in approving three new convergence
transactions upon a showing of loss of economies are consistent with the
recommendations set forth in the 1995 Report. In approving the formation of New
Century Energies as a combination gas and electric registered holding company,
the Commission stated:

                  The Commission has previously taken notice of developments
                  that have occurred in the gas and electric industries in
                  recent years, and has interpreted the Act and has analyzed
                  proposed transactions in light of these changed
                  circumstances... The gas and electric industries are
                  converging, and, in these circumstances, separation of gas and
                  electric businesses may cause the separated entities to be
                  weaker competitors than they would be together. This factor
                  adds to the quantifiable loss of economies caused by increased
                  costs.

New Century Energies, Inc., Holding Co. Act Release No. 26748 at 30-31.

                  Most importantly, the Commission distanced itself from the
earlier more restrictive precedent of the decision in New England Electric
System, 41 S.E.C. 888 (1964) ("NEES") stating:

                  In the 1960s, when the NEES case was decided, utilities were
                  primarily franchised monopolies with captive ratepayers, and
                  competition between suppliers of gas and electricity, however
                  limited, was virtually the only source of customer choice and
                  was thus deemed beneficial to energy consumers. The fact that
                  other gas utilities of comparable size could operate
                  successfully on an independent basis was evidence that a gas
                  system could also operate on its own, a desirable result,
                  without a substantial loss of economies. The empirical basis
                  for these assumptions, however, is rapidly eroding. Although
                  franchised monopolies are still the rule, competition is
                  increasing. Increased expenses of separate operation may no
                  longer be offset, as they were in New England Electric System
                  by a gain of qualitative competitive benefits, but rather may
                  be compounded by a loss of such benefits...

New Century Energies, Inc., Holding Co. Act Release No. 26748 at 32.

                 The logic of the New Century Energies decision is equally
compelling in the instant situation. It is the intention of the Applicants that
the separate gas properties of the Applicants be integrated and operated as a
single economic system in conjunction with Applicants' electric system in order
to better provide competitive comprehensive energy services to Applicants'
customers. Because today the properties are operated as separate entities and
Section 11(b)(1)(A), (B) and (C) appear to require an analysis of "[e]ach such
additional system," the original loss-of-economies analysis looked at
divestiture as three separate gas systems, preserving their present status of
being independent from one another, which produced annual lost economies that
are estimated to be $34.3 million per annum. If the gas integration and
coordination plan discussed above was in effect and these properties were to be
divested as a single multistate gas utility company, annual lost economies are
still estimated to be $27.4 million per annum.
         
         In either case, the lost economies are substantial in an industry in
which there are already many companies competing with Applicants for the
provision of comprehensive energy services in Applicants' service territory
and, where there is not yet competition, lost economies may well result in
increased retail rates. Competition between energy suppliers can only benefit
consumers. Increasingly, the competitors are themselves suppliers of
comprehensive energy services just like New Century Energies, Inc., TUC Holding
Company and Houston Industries Incorporated.

         The chief savings achieved by operation of the three properties as a
single multistate gas property arises from the complete elimination of the
administrative costs of one of the larger companies. The non-field operations
are assumed to be met by the executive and administrative operations of the
other two companies. Thus, the $34.3 million of annual lost economies of
operating as three companies becomes $27.4 of lost economies on and integrated
basis, which as the following table shows is still significant in a very
competitive industry:

</TABLE>

         The Applicants have prepared and submitted as Exhibit L-6 a
Supplemental Study analyzing the impact of the divestiture of their gas
operations (the "Supplemental Study"). The Supplemental Study focuses on the
combined gas properties of the Applicants creating one gas system.

         Section 11(b) (1) of the Act generally requires a registered holding 
company system to limit its operations "to a single integrated public utility
system, and to such other businesses as are reasonably incidental, or
economically necessary or appropriate to the operations of such integrated
public utility system." Section 11(b) (1) of the Act expressly permits a
registered holding company to control one or more "additional integrated public
utility systems" if (A) each of such additional systems cannot be operated as an
independent system without the loss of substantial economies which can be
secured by the retention of control by such holding company of such system; (B)
all of such additional systems are located in one state, adjoining states, or a
contiguous foreign country; and (C) the continued combination of such systems
under the control of such holding company is not so large (considering the state
of the art and the area or region affected) as to impair the advantages of
localized management, efficient, efficient operation, or the effectiveness of
regulation.

         The Commission has consistently relied upon the Supreme Court decisions
in SEC v. New England Elec. Sys., 390 U.S. 207 (1968) ("NEES I") and SEC v. New
England Elec. Sys., 390 U.S. 207 (1968) ("NEES II") to interpret Clause (A) of
Section 11(b)(1). Moreover, to determine whether lost economies are
"substantial" for purposes of Section 11(b)(1)(A), the Commission has
consistently given consideration to four ratios cited in the cases. These ratios
measure the projected loss of economies of a potential divestiture as a
percentage of: (1) total gas operating revenues, (2) total gas expense or
"operating revenue deductions," (3) gross gas income, and (4) net gas income or
net gas utility operating income. Although the ratios are not bright-line rules
to identify substantial lost economies, the Commission suggested in an early
leading decision that cost increases resulting in a 6.78% loss of operating
revenues, a 9.72% increase in operating revenue deductions, a 25.44% loss of
gross income and a 42.46% loss of net income would afford an "impressive basis
for finding a loss of substantial economies." Engineers Public Service Co., 12
SEC 41, 59 (1942), rev'd on other grounds and remanded, 138 F.2d 936 (D.C. Cir.
1943), vacated as moot, 332 U.S. 788 (1947).

         The Supplemental Study submitted as Exhibit L-6 by the Applicants
indicates that the costs increases that would result from sever ance of the gas
properties would satisfy, and in almost all instances exceed, those thresholds.

         As set forth in the Supplemental Study, divestiture of the gas
operations of WPLH, IES and IPC into one stand-alone company would result in
lost economies of approximately $27.9 million. On a percentage basis, the
Supplemental Study indicates that divesture of the gas operations would amount
to 8.45% of total gas operating revenues, 9.65% of total gas operating revenue
deductions, 68.11% of gross gas income and 101.71% of net gas income.

         The Supplemental Study indicates further that in order to recover these
lost economies, the single, new stand-alone company divested from MPLH, IES and
IPC would need to increase customer rates by 8.45% ($27.9 million) in order to
provide a 10.39% rate of return on rate base. In the absence of rate relief, the
Supplemental Study concludes that the lost economies would result in
approximately a 5% rate of return on rate base for the gas operations.
   
         ii.     Retention of Other Businesses

         As  a  result  of  the  Transaction,  the  non-utility  businesses  and
interests  of WPLH,  IES and IPC  described  in Item  1.B.5.  above will  become
businesses and interests of Interstate  Energy.  Certain of such businesses will
be held directly by Interstate Hold. In addition,  the subsidiaries,  affiliates
and   associates  of  these   non-utility   businesses   will  become   indirect
subsidiaries, affiliates and associates, respectively, of Interstate Energy.

         As  noted  above,  prior  to  consummation  of the  Transaction,  a new
wholly-owned  subsidiary,  Interstate  Hold,  will be established by WPLH.  Upon
consummation of the Transaction,  Interstate Hold will be a direct  wholly-owned
subsidiary of Interstate  Energy which will replace HDC and  Diversified  as the
holding company for many of the non-utility  subsidiaries  and interests of WPLH
and IES. To accomplish this new structure,  HDC and  Diversified  will be merged
into  Interstate  Hold and the existing  1.9%  minority  interest in HDC will be
eliminated.  Corporate  charts  showing  the  existing  subsidiaries,  including
non-utility subsidiaries,  of WPLH and IES, are filed as Exhibits M-1 and M-2
and updated by Exhibits M-4 and M-5. A corporate chart showing the projected
arrangement of these  subsidiaries  under Interstate  Energy is filed as Exhibit
A. To  simplify  further  its  corporate structure,  Interstate Energy may
combine certain of its non-utility  businesses which it is authorized to retain
by the Commission following the Transaction.

         Standard for retention:  Section 11(b)(1) permits a registered  holding
company to retain  "such  other  businesses  as are  reasonably  incidental,  or
economically  necessary or  appropriate,  to the  operations of [an]  integrated
public utility system." Under the cases interpreting  Section 11, an interest is
retainable if (1) there is an operating or functional  relationship  between the
operations  of the  utility  system and the  non-utility  business  sought to be
retained,  and  retention  is in the public  interest(27) or if (2) the business
evolved out of the system's utility business,  the investment is not significant
in relation to the system's total  financial  resources,  and the investment has
the  potential  to  produce  benefits  for  investors  and/or  consumers.(28) In
addition,  the  Commission  has  stated  that  "retainable non-utility interests
should   occupy   a  clearly  subordinate  position  to  the  integrated  system
constituting the primary business of the registered holding company."29

                                       69
<PAGE>   74

         The majority of Interstate  Energy's  non-utility  businesses  would be
considered  energy-related  companies under the  Commission's  proposed Rule 58.
Under proposed Rule 58, an  energy-related  company is a company that derives or
will derive  substantially  all of its  revenues  (exclusive  of  revenues  from
temporary  investments) from one of the twelve businesses  described in the Rule
and from such other  activities  and  investments  as the Commission may approve
under Section 10.

         In the 1995 Report, in addition to the proposed Rule 58 safe harbor for
energy-related  diversification,  the  Division  suggested  the adoption of a de
minimus "budget approach" for limited investments in activities which do not fit
within previous orders of the Commission, yet appear to be within the meaning of
the "other  businesses"  clauses of Section 11. The Division suggested that this
approach would allow registered  holding  companies to make minimal  investments
without  regard to the identity of each  investment  up to a certain  authorized
amount,  provided certain structural  considerations were observed which limited
the  potential  losses to the amount of the  investment  and insulated the other
system assets by isolating the activity in a separate subsidiary.(30)

         Upon  the  consummation  of the  Transaction,  each of the  non-utility
investments  retained by Interstate Energy from WPLH and those to be acquired by
Interstate  Energy from IES and IPC will become subject to the  jurisdiction of,
and regulation by, the PSCW pursuant to the Wisconsin Act as described  above in
Item  1.B.1.a.  The policy of the Wisconsin Act is set forth in its preamble and
explicitly recognizes that the financial health of a public utility depends upon
the  economic  well-being  of its  service  area and  encourages  the conduct of
substantial  business by the utility  within the  service  area by,  among other
things,   providing  investment  capital  for  new  ventures.  To  foster  these
objectives,  and to ensure safe and reliable  service at competitive  rates, the
Wisconsin  Act  contains  provisions  concerning  oversight  by the  PSCW of the
diversification  and  community  investment  permitted  and  encouraged  by  the
statute.(31)  As  previously  described,  among other  things,  the  Wisconsin
Act provides  for  (1)  a  cap  on  amounts  invested  in  diversified
non-utility businesses;  (2) annual reporting  requirements with respect to the
total amount of assets held by non-utility  affiliates,  amounts located within
the state and number of employees;  and (3) periodic investigations by the state
commission at least every three years.  Furthermore,  the PSCW is required to
consider whether the non-  utility  affiliates  (1)  substantially  retain,
attract  or  promote business  activities or employment or provide capital to
businesses being formed or operating in the service  territory of any public
utility  affiliate;  or (2) develop or operate  commercial or industrial  parks
in the service  territory of any public utility affiliate. Each non-utility
investment retained by Interstate Energy from WPLH has been  subject to analysis
by the PSCW in  accordance  with these  requirements,  and each non-utility
investment retained (including those obtained  from IES and IPC) will be
subject  to  ongoing  regulation  under the Wisconsin Act. Because the extensive
regulation to which these investments will be subject  ensures such  investments
are and will be in the best  interests of investors and consumers,  the
Commission  should allow  retention  under Section 11's "other businesses"
clause.

         As set forth more fully in Exhibit M-5, the non-utility  business
interests that Interstate  Energy  will  hold  through   Interstate  Hold  or
through  utility subsidiaries meet the Commission's standards for retention.





                                       70
<PAGE>   75
         In addition to these specific factors in support of retention, a number
of more general  considerations  support  Interstate  Energy's  retention of the
non-utility businesses of





                                       71
<PAGE>   76

WPLH,  IES and IPC.  First,  the  businesses  in  question  provide  benefits to
customers,  investors and the public.  Second,  the  Transaction is, at heart, a
utility  combination,  in which the  non-utility  businesses  are small and only
incidentally  involved,  amounting,  in the  aggregate,  to less than 15% of the
consolidated  assets and 12% of consolidated  revenues of the Interstate  Energy
system.  Third,  this is not a case in  which  an  existing  registered  holding
company system is acquiring new non-utility interests; rather, Interstate Energy
is only seeking  authorization to retain the non-utility interests held by WPLH,
IES and IPC before the Transaction.  Finally,  state holding company  regulation
has developed  (such as the Wisconsin Act) which dictates what  investments  are
"necessary or  appropriate in the public  interest" and are "not  detrimental to
the proper  functioning" of a holding company.  WPLH's  investments were made in
accordance  with  the  rigorous  statutory  limitations  of  the  Wisconsin  Act
applicable to non-utility diversification and continue to be subject to periodic
audits by the PSCW under the Wisconsin  Act. When held by Interstate  Energy all
of the  non-utility  businesses  of  Interstate  Energy  will be subject to such
review.

         Rule 53  requires  that  aggregate  investments  in EWGs and  FUCOs not
exceed 50% of the system's  consolidated  retained earnings.  As of December 31,
1995,  WPLH,  IES  and IPC had no  investments  in  EWG's  and  their  aggregate
investments in FUCOs was less than 2% of combined retained earnings, well within
the amount permitted.

         Proposed Rule 58 would require that the aggregate investment in "energy
related"  companies  not  exceed  15% of the  consolidated capitalization  of a
registered holding company. As of December 31, 1995, the aggregate investment in
"energy  related"  companies  of  WPLH,  IES  and IPC would  come  within  that
limitation. Because these businesses pre-existed the application of the Act to
WPLH, IES and IPC, it is not intended to rely on Rule 58 for retention of the
businesses but rather to rely on the legal precedents discussed in Exhibit M-5
hereto which is hereby incorporated by reference to this Item 3.A.2.a.ii.


         b.      Section 10(c)(2)

         The   Transaction   will  tend  toward  the  economical  and  efficient
development of an integrated  public utility system,  thereby serving the public
interest, as required by Section 10(c)(2) of the Act.

         i.      Efficiencies and Economies

         The  Transaction  will produce  economies  and  efficiencies  more than
sufficient  to satisfy  the  standards  of Section  10(c)(2),  described  above.
Although  some of the  anticipated  economies  and  efficiencies  will be  fully
realizable only in the longer term, they are properly  considered in determining
whether the standards of Section  10(c)(2) have been met. See American  Electric
Power Co., 46 S.E.C.  1299,  1320-21 (1978).  Some potential  benefits cannot be
precisely  estimated;  nevertheless  they  too are  entitled  to be  considered:
"[S]pecific dollar forecasts of future savings are not necessarily  required;  a
demonstrated  potential  for  economies  will  suffice  even when  these are not
precisely quantifiable." Centerior Energy Corp., Holding Co. Act Release No.
24073 (April 29, 1986).

<PAGE>   77
         Despite the passage of time since the first filing of Form U-1 under
the Act, WPLH,  IES and IPC still believe  the  nominal  dollar  net  value of
synergies from the Transaction to be  approximately  $749 million over the first
10-year period from 1997 to 2006.  The  Transaction is expected to yield several
types of presently  quantifiable  benefits:  (1) corporate and operations  labor
cost  savings;  (2)  corporate and  administrative  programs  cost savings;  (3)
non-fuel purchasing  economies savings; (4) production cost savings; and (5) gas
supply cost savings.  The amount of savings currently estimated in each of these
categories, on a nominal dollar basis, is summarized in the table below:

</TABLE>


         These expected savings far exceed the savings claimed in a number of
recent acquisitions approved by the Commission.  See, e.g., Kansas Power and
Light Co., Holding Co. Act Release No. 25465 (Feb. 5, 1992) (expected savings
of $140 million over five years); IE Industries, Holding Co. Act Release No.
25325 (June 3, 1991) (expected savings of $91 million over ten years); Midwest
Resources, Holding Co. Act Release No. 25159 (Sept. 26, 1990) (estimated
savings of $25 million over five years).  These savings categories are
described in greater detail below.

                 Corporate  and  Operations   Labor  Cost  Savings:   Applicants
         estimate  that a net reduction in labor costs of  approximately  $380.5
         million on a nominal  dollar  basis can be  achieved as a result of the
         Transaction   through   elimination  of  approximately  600  full  time
         equivalent  duplicative  positions in certain  corporate and operations
         functions.

                 Corporate  and  Administrative  Programs  Savings:   Applicants
         estimate  that a reduction in non-labor  corporate  and  administrative
         expenses  totalling  approximately  $149.1  million on a nominal dollar
         basis can be achieved through consolidation of duplicative programs and
         spreading  expenses over greater asset or customer bases. These include
         savings  related  to  information  systems,  insurance  costs,  outside
         services,  shareholder  services,  benefits  administration  and  other
         general and administrative overheads. The aggregate cost of these items
         for the companies on a stand-alone basis




                                       73
<PAGE>   78

         is greater than the cost will be to the combined new company.  An
         example would be the hiring of one outside professional service
         (external auditors, attorneys, consultants, etc.) instead of three.

                 Non-Fuel  Purchasing  Economies Savings:  These are the savings
         which  will  result  from  the  new,   larger  company  having  greater
         purchasing  power.  Interstate  Energy will be able to  coordinate  its
         purchasing needs, buy in greater  quantity,  negotiate with vendors and
         receive  larger   discounts.   Applicants   estimate  cost  savings  of
         approximately  $60.2  million  on a  nominal  dollar  basis  from  such
         economies.

                 Production  Cost Savings:  Applicants  estimate that production
         cost savings  (including fuel savings) of approximately  $220.9 million
         on a nominal  dollar basis will result from the  combined  operation of
         the three companies' generation and transmission systems, including the
         integrated   economic  dispatch  of  such  systems  and  electric  fuel
         procurement  savings.  WPLH, IES and IPC currently  commit and dispatch
         their respective systems on an "economic dispatch" basis; that is, each
         company  commits and dispatches its generating  system to meet the load
         in such manner as to minimize  production costs.  There are differences
         in incremental  cost between the three  systems,  as well as generation
         available on each system during most hours.  Interstate  Energy will be
         able to take advantage of these factors by committing  and  dispatching
         the lowest cost  generation  from WP&L,  Utilities and IPC to serve the
         total  load of  Interstate  Energy  at a cost  that is  lower  than the
         combined cost of the three stand-alone companies.

                 Gas  Supply  Cost  Savings:   Applicants  estimate  savings  of
         approximately  $23.6 million on a nominal  dollar basis can be achieved
         by the  combined  companies  in gas  supply  costs by  optimization  of
         transportation capacity on various gas pipelines, improving utilization
         of  no-notice  service,   shortening  storage  withdrawal  periods  and
         avoiding duplication of reserve margins through supply integration.

         (less)

                 Costs  to  Achieve:  This  consists  of  merger  costs  such as
         investment  bankers' fees,  attorney and accountant fees, and severance
         and other employee  reduction-related costs. Item 2 provides details of
         some of these components and their amounts.

                 Additional  Expected  Benefits:  In  addition  to the  benefits
         described  above,  there  are other  benefits  which,  while  presently
         difficult  to  quantify,  are  nonetheless  substantial.   These  other
         benefits  include   maintenance  of  competitive  rates  and  services,
         increased size and  stability,  diversification  of service  territory,
         coordination of  diversification  programs,  complementary  operational
         functions and complementary management.

                 Maintenance of  Competitive  Rates:  Interstate  Energy will be
         more   effective  in  meeting  the   challenges  of  the   increasingly
         competitive  environment in the utility  industry than any of WPLH, IES
         or IPC standing alone due to the economies of scale available




                                       74
<PAGE>   79

         to Interstate Energy. The impact of these economies of scale, which are
         described in greater  detail  below,  will help to position  Interstate
         Energy to deal effectively  with increased  competition with respect to
         rates. The Mergers,  by creating the potential for increased  economies
         of scale,  will create the  opportunity  for  strategic,  financial and
         operational  benefits  for  customers  in the form of more  competitive
         rates  over the long term and for  shareowners  in the form of  greater
         financial strength and financial flexibility.

                 Integration   of  Corporate   and   Administrative   Functions:
         Interstate  Energy will be able to  consolidate  certain  corporate and
         administrative  functions  of WPLH,  IES and IPC,  thereby  eliminating
         duplicative   positions,   reducing  other   non-labor   corporate  and
         administrative   expenses   and   limiting  or   avoiding   duplicative
         expenditures  for  administrative  and  customer  service  programs and
         information  systems.  A joint  transition  task force is examining the
         manner  in  which  to  best  organize  and  manage  the  businesses  of
         Interstate Energy and identify  duplicative  positions in the corporate
         and  administrative  areas.  It is  anticipated  that,  as a result  of
         combining  staff  and  other  functions,  Interstate  Energy  will have
         somewhat  fewer  employees  within several years than WPLH, IES and IPC
         currently  have in the  aggregate.  WPLH,  IES and IPC are committed to
         achieve  cost  savings  in the  area of  personnel  reductions  through
         attrition,  strictly  controlled hiring, and reassignment and retaining
         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 are expected to
         be realized.

                 Reduced  Operating  Costs:  The  combination  should  result in
         decreased  electric  production costs through the joint dispatch of the
         systems.  Natural gas supply savings  through  combined  purchasing are
         also anticipated.

                 Purchasing  Economies  and  Streamlining  of  Inventories:  The
         combination of the three companies should result in greater  purchasing
         power for items such as fuel and  transportation  services  and general
         and  operational  goods and 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:  WPLH and IES each
         have significant non-utility subsidiaries,  and Interstate Energy, as a
         stronger  financial  entity,  should be able to manage and pursue  such
         subsidiary  businesses more efficiently and  effectively.  WPLH and IES
         currently engage in a number of diversified  businesses,  some of which
         are  complementary.  To the extent such  complementary  businesses  are
         combined   and  able  to   collaborate   in  the   pursuit   of  market
         opportunities,  benefits from economies of scale should be obtained and
         thereby improve the performance of these businesses.  Furthermore,  due
         to  the  larger  capital  base  of  Interstate  Energy,  the  financial
         flexibility will exist to support the existing businesses as well as to
         advantage of new business opportunities as they arise.

                 More  Diverse   Service   Territory:   The   combined   service
         territories of WP&L,  Utilities and IPC will be larger and more diverse
         than  any of the  service  territories  of  WP&L,  Utilities  or IPC as
         independent   entities.   This  increased   customer  and  geographical
         diversity  is expected to reduce the  exposure to changes in  economic,
         competitive or climatic  conditions in any given sector of the combined
         service territory.

         Expanded Management Resources:  In combination,  WPLH, IES and IPC will
be able to draw on a larger and more  diverse mid- and  senior-level  management
pool  to  lead  Interstate   Energy  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 Interstate Energy should
also benefit from new opportunities in the expanded organization.

         ii.     Integrated Public Utility System

                 I.       Electric System

         As applied to electric utility  companies,  the term "integrated public
utility system" is defined in Section 2(a)(29)(A) of the Act as:

                 a system  consisting of one or more units of generating  plants
                 and/or transmission lines and/or distributing facilities, whose
                 utility assets,  whether owned by one or more electric  utility
                 companies, are physically interconnected or capable of physical
                 interconnection  and  which  under  normal  conditions  may  be
                 economically   operated   as  a   single   interconnected   and
                 coordinated  system  confined in its operation to a single area
                 or  region,  in one or more  states,  not so large as to impair
                 (considering  the  state  of the  art and  the  area or  region
                 affected)  the  advantages of localized  management,  efficient
                 operation, and the effectiveness of regulation.

On the basis of this statutory  definition,  the Commission has established four
standards  that must be met before the  Commission  will find that an integrated
public utility system will result from a proposed acquisition of securities:

        (1)     the utility assets of the system are physically interconnected
        or capable of physical interconnection;

        (2)     the utility assets, under normal conditions, may be
        economically operated as a single interconnected and coordinated system;

        (3)     the system must be confined in its operations to a single area
        or region; and





                                       76
<PAGE>   81

         (4) the system must not be so large as to impair (considering the state
         of the art and the area or region affected) the advantages of localized
         management, efficient operation, and the effectiveness of regulation.

Environmental Action, Inc. v. S.E.C., 895 F.2d 1255, 1263 (9th Cir. 1990)
(citing In re Electric Energy, Inc., 38 S.E.C. 658, 668 (1958)).  The
Transaction satisfies all four of these requirements.  It should be noted that
in the 1995 Report, the Division recommended that the Commission "respond
realistically to the changes in the utility industry and interpret more
flexibly each piece of the integration equation."(32)
     First, as described in Item 1.B.3.  above, the Utilities system and the IPC
system are  physically  connected  by three  161kV lines and the East 345 kV
Line. In addition,  the WP&L system and the combined  Utilities/IPC  systems are
capable of  interconnection  through the  construction  of two new  transmission
tie-lines,  construction of which is planned for completion within five years of
the effective time of the Transaction.  When authorized by FERC, a 69 kV
tie-line approximately 3.5 miles in length will be constructed  across the
Mississippi  River  connecting  WP&L's Hillside  substation  near Prairie du
Chien,  Wisconsin  with IPC's 69kV line at MacGregor,  Iowa on the west  side of
the  river.  This  overhead  line  will be constructed on a right-of-way from a
previously existing connection between WP&L and IPC  which  remains  under
their  control.  Also,  a 161 kV  overhead  line approximately  2.5 miles in
length will be  constructed  across the  Mississippi River from WP&L's  Nelson
Dewey  generating  plant on the east to IPC's  Turkey River  substation  on the
west  side  of the  river.  The  capability  of  this interconnection  would be
approximately  200 MW. It is currently  estimated that the total cost associated
with constructing the interconnection lines will be $4 million (in 1996
dollars).
         These additional  interconnects  will further the economic operation of
the   Interstate   Energy   system  by   enabling   it  to  achieve   additional
production-related  synergies. Indeed, the plans for the construction of the two
lines  are  not  related  to any  requirement  of the  Act,  but  rather  to the
substantial benefits that will accrue as a result of the lines.

         The Commission has previously indicated that a single integrated system
exists even based solely on a planned,  future  interconnection,  provided  that
such physical  interconnection  is  "contemplated  or . . . possible  within the
reasonably  near future" and not just  something that "might occur in the remote
future, and whose occurrence has not been foreshadowed by any facts shown in the
record."(33) The benefits to be derived by the new transmission lines are also a
factor  in   determining   whether   the   system   is   capable   of   physical
interconnection.(34)  The fact that the  Commission has indicated  that,  absent
special circumstances,  the "reasonably near future" mentioned above, should not
exceed 10 years,  (35) is not an issue in this case as the parties have definite
plans  to  construct  the  two  interconnections  that  will be in  service  and
generating economies within 5 years of the consummation of the Transaction.

         Second,  WP&L,  Utilities  and IPC will be  economically  operated as a
single  interconnected  and  coordinated  system.  The  combined  system will be
centrally and economically





                                       77
<PAGE>   82

dispatched and generating units committed as a single  integrated  system.  Upon
consummation of the Transaction,  WP&L,  Utilities,  IPC and Interstate Services
will enter into the Coordination Agreement which will be filed with and approved
by FERC.  The  Coordination  Agreement  will  provide for joint  dispatch of the
combined generating  resources of WP&L,  Utilities and IPC, and will contain the
terms,  conditions  and payment  provisions  associated  with energy  exchanges,
resource  sharing and other  transactions  among the companies.  Pursuant to the
Coordination  Agreement,  generation and tie-line data of all three systems will
be fed into a common  dispatch  computer to  economically  dispatch the combined
system  taking into account the existing  1,339 MW of  interconnection  capacity
between IPC and  Utilities and the proposed 250 MW of  interconnection  capacity
between IPC and WP&L. The studies which projected the level of production  costs
savings   in  this   Application/Declaration   were   based   upon   this   same
interconnection  capacity.  In  order  to  facilitate  joint  economic  dispatch
throughout the Interstate Energy system,  applicants  anticipate that Interstate
Energy will enter into one or more contractual  arrangements for the purchase of
200 MW of firm transmission service between the IPC and WP&L systems from one of
three neighboring electric systems, each of which has indicated that it has such
service  available  for sale to WP&L and/or  IPC.  Such  purchased  transmission
service will  generally be  sufficient  to facilitate  joint  economic  dispatch
throughout the Interstate  Energy system.  However,  there may be instances when
transactions in excess of 200 MW between the Iowa and Wisconsin  portions of the
Interstate   Energy   system   will  be  made  based  upon   economic   dispatch
opportunities.  In such situations,  additional  non-firm  transmission  service
would  be  purchased,  subject  to  availability,  from  one of the  neighboring
electric systems.

         As  members of MAPP,  both IPC and  Utilities  are  subject to the MAPP
transmission use agreement and the MAPP loss reimbursement agreement. These MAPP
agreements  identify  third party impacts for member  transactions  and make the
appropriate  charges to  transacting  parties so that third parties  within MAPP
receive  transmission  line use fees and line loss  reimbursement.  Transactions
between IPC,  Utilities and WP&L which are required for joint economic  dispatch
purposes will be covered under these MAPP  agreements.  Thus,  MAPP members will
receive  compensation  for third  party  impacts  caused  by the joint  economic
dispatch  activities of the utility  subsidiaries of Interstate  Energy. No such
mechanism  exists nor is one required for compensation of third party impacts on
non-MAPP utilities.

         For  integration  purposes  under  the Act,  what is  relevant  is that
Interstate Energy will have sufficient internal  transmission  capacity to fully
accommodate  the  anticipated  transfers  between WP&L,  Utilities and IPC under
central economic dispatch, and will obtain transmission service from neighboring
utilities to accommodate any transfers that might exceed the capabilities of its
system.

         Third, the integrated Interstate Energy electric system will operate in
a single  area or region.  The system  will  operate in four  contiguous  states
(Wisconsin,  Iowa,  Illinois  and  Minnesota)  in the north  central area of the
United States  delineated  on Exhibit G-4. In the 1995 Report,  the Division has
stated  that the  evaluation  of the  "single  area or  region"  portion  of the
integration   requirement   "should  be  made...  in  light  of  the  effect  of
technological  advances on the ability to transmit electric energy  economically
over longer distance, and other developments





                                       78
<PAGE>   83

in the  industry,  such as brokers  and  marketers,  that  affect the concept of
geographic integration."(36) The 1995 Report also recommends primacy be given to
"demonstrated   economies   and   efficiencies   to  satisfy   the   integration
requirements."(37)  As set forth in Item 3.A.2.b.i,  the Transaction will result
in economies and efficiencies for the utilities and, in turn, their customers.

         Fourth,  the Interstate  Energy electric system will not be so large as
to impair the advantages of localized management,  efficient operations, and the
effectiveness  of  regulation.  The  Commission's  past  decisions on "localized
management"  show  that  the  Transaction  fully  preserves  the  advantages  of
localized  management.  In such cases,  the Commission  has evaluated  localized
management in terms of: (i) responsiveness to local needs, see American Electric
Power Co.,  Holding Co. Act Release No.  20633 (Jul.  21, 1978)  (advantages  of
localized  management  evaluated in terms of whether an enlarged system could be
"responsive to local needs");  General Public  Utilities Corp., 37 S.E.C. 28, 36
(1956) (localized  management  evaluated in terms of "local problems and matters
involving relations with consumers"); (ii) whether management and directors were
drawn from local utilities,  see Centerior Energy Corp., Holding Co. Act Release
No. 24073  (April 29, 1986)  (advantages  of localized  management  would not be
compromised  by the  affiliation of two electric  utilities  under a new holding
company because the new holding company's  "management [would be] drawn from the
present management" of the two utilities);  Northeast Utilities, Holding Co. Act
Release No. 25221 (December 21, 1990) (advantages of localized  management would
be preserved in part because the board of the New Hampshire  Utility,  which was
to  be  by  an  out-of-state  holding  company,  included  "four  New  Hampshire
residents");  (iii) the  preservation  of corporate  identities,  see  Northeast
Utilities,  Holding Co. Act Release No. 25221  (December  21,  1990)  (utilities
"will be maintained as separate New Hampshire  corporations...  [t]herefore  the
advantages of localized  management  will be  preserved");  Columbia Gas System,
Inc.,  Holding Co. Act Release No.  24599  (March 15,  1988)  (benefits of local
management  maintained  where  the  utility  to be  added  would  be a  separate
subsidiary);  and (iv) the ease of  communications,  see American Electric Power
Co.,  Holding Co. Act Release No. 20633 (Jul.  21, 1978)  (distance of corporate
headquarters  from local  management was a "less important factor in determining
what is in the public  interest" given the "present-day  ease of  communications
and transportation").

         The Transaction satisfies all of these factors. WP&L, Utilities and IPC
will continue to operate through regional  offices with local service  personnel
and line crews available to respond to customers'  needs.  In addition,  the new
management  and Board of Directors of Interstate  Energy is expected to be drawn
primarily from the existing  management  and boards of WPLH,  IES, IPC and their
subsidiaries.

         After the  Transaction,  WP&L,  Utilities and IPC will  maintain  their
current   headquarters  as  subsidiary   headquarters  and  as  local  operating
headquarters  for the areas they presently serve,  while Interstate  Energy will
maintain system headquarters in Madison, Wisconsin. Although the location of the
corporate headquarters of Interstate Energy will add distance from customers who
are served by Utilities and IPC, this distance is, as noted by the Commission in
the American Electric Power case, a relatively unimportant factor given the





                                       79
<PAGE>   84

present  ease of  transportation  and  communications  and the  retention of the
headquarters  of Utilities and IPC at their present  locations.  This  structure
will preserve all the benefits of localized  management WP&L,  Utilities and IPC
presently enjoy while simultaneously allowing for the efficiencies and economies
that will  derive  from their  strategic  alliance.  Furthermore,  as  described
earlier, the system will facilitate efficient operation.

         Additionally,   the  Interstate  Energy  system  will  not  impair  the
effectiveness of state regulation.  WP&L,  Utilities and IPC will continue their
separate existence as before and their utility operations will remain subject to
the same regulatory  authorities by which they are presently  regulated,  namely
the PSCW,  IUB, ICC,  MPUC,  the FERC and the NRC.  WP&L,  Utilities and IPC are
working closely with the PSCW, IUB, ICC and MPUC as well as the FERC and the NRC
to ensure they are well informed about this  Transaction,  and this  Transaction
will not be consummated unless all required  regulatory  approvals are obtained.
Pursuant to the  recommendations  contained in the 1995 Report, this last factor
is  significant.  As the Division  stated  therein "when the affected  state and
local  regulators  concur,  the  [Commission]  should  interpret the integration
standard flexibly to permit non-traditional  systems if the standards of the Act
are  otherwise  met,"(38)  especially  since this  Transaction  will result in a
system similar to the traditional registered holding company system.

                  IEC will be an integrated electric system within the meaning
of Section 2(a)(29)(A) of the Act. IEC will be operated as a single system,
economically dispatched pursuant to the Coordination Agreement. Utilities and
IPC ("IEC West") are presently directly interconnected(39) and WP&L and South
Beloit ("IEC East") are presently directly interconnected.(40) IEC West and IEC
East are presently interconnected through firm contractual wheeling arrangements
with third parties(41) and through MAPP.(42) Additionally, IEC intends to build
two tie-lines (aggregating 250 MW of transfer capability) between IEC West and
IEC East.(43) In the Federal Energy Regulatory Commission Initial Decision on
Rate and Merger Issues (Issued July 3, 1997) (the "Initial FERC Decision"), the
Administrative Law Judge, however, ordered the Applicants to delay construction
of the tie-lines between IEC West and IEC East until the Applicants have
constructed 400 MW of additional simultaneous import capability into the
Wisconsin Upper Michigan System ("WUMS"). IES Utilities et al, 80 F.E.R.C.
Paragraph 63,001, 21 (1997).

                 On November 12, 1997, the Federal Energy Regulatory Commission
(the "FERC") issued its decision on the merger. IES Utilities, Inc. et al.,
Opinion No. 419, 81 FERC Paragraph 61, ___ (1997) ("Opinion No. 419"). In
Opinion No. 419, the FERC accepted a competition stipulation that had been
negotiated by the Applicants and the FERC trial staff, as modified to include an
extra condition imposed by the presiding Administrative Law Judge. The
competitive stipulation, as modified, generally addresses the Applicants' use of
firm transmission service purchased from ComEd and DPC in order to achieve joint
dispatch; Applicants' proposal to construct two additional transmission lines
between IEC West and IEC East at a future time; Applicants' proposal to make
eight specified transmission improvements to increase transfer capability into
WUMS; Applicants' obligation to purchase additional point-to-point transmission
service if joint dispatch transfers between IEC West and IEC East exceed the
contract path quantity; and alternative dispute resolution and additional
efforts to increase transfer capability into WUMS if the specified measures are
not fully successful.

                  The record developed in the FERC proceeding demonstrates that,
at present, although IEC West and IEC East are interconnected through
neighboring utilities, there are no high voltage connections directly between
Iowa and WUMS. Initial FERC Decision at 30. Additionally, the transmission
capability between Iowa and WUMS is limited. In short, power cannot go straight
from Iowa to WUMS but must flow across the grid which is already constrained. As
a result of physics, due to the nature of the way power flows across the grid
and the engineering peculiarities of the Iowa-WUMS interface, the joint dispatch
of the Applicants' generating facilities through use of their 200 MW of
transmission rights(44) will result in the Applicants' using up much of the
import capability into WUMS thereby during times of system constraint preventing
competitors of the Applicants from selling power into WUMS.

                  The immediate construction of the tie-lines(45) will, for
reasons of physics and engineering peculiar to the Iowa-WUMS interface, not
alleviate the congestion at the constrained interface. Accordingly, the Initial
Decision and Opinion No. 419 direct the Applicants to delay construction of
their new tie-lines until the Applicants construct additional facilities to
increase the overall transfer capability into WUMS. The construction of these
additional facilities will reinforce the electrical interconnection between Iowa
and WUMS. The requirements of the competitive stipulation adopted by Opinion No.
419 are only necessary because, as a factual, physics and engineering matter,
the Applicants are currently interconnected and capable of integrated operation
to the point where they must first provide transmission capacity for others
before construction of the tie-lines.

                 The type and degree of physical interconnection described in
the Initial FERC Decision is sufficient to establish interconnection under the
Act for the purposes of Sections 2(a)(29)(A), 10(c)(2) and 11(b)(1). The
Commission has found that proposals to contract for or to construct physical
connections between utilities in a single system satisfy the interconnection
requirement. See New England Electric System, 38 S.E.C. 193, 198-99 (1958)
(engineering studies and testimony showing feasibility of direct
interconnections among four small systems satisfied the requirements of the Act
that utilities be "capable of physical interconnection"); Mississippi Valley
Generating Co., 36 S.E.C. 159 (1955) (while complete direct physical
interconnection between the companies involved did not currently exist, the
Commission recognized that physical interconnection was possible through the
construction of transmission lines).

               Additionally, the Commission has found that two utilities that
are capable of sharing power through wheeling or power pool arrangements (as the
Applicants will be forced to do upon consummation of the Transaction pending
further construction of new transmission facilities) are physically
interconnected or capable of physical interconnection. The fact that two
facilities may be separated by other facilities that are not owned by the
holding company does not change the fact that they are interconnected or capable
of physical connection and of supplying power to one another as needed. City of
New Orleans v. SEC, 969 F.2d 1163, 1165 (D.C. Cir. 1992).

               The Commission has also acknowledged that utilities can be
interconnected through power pools or by means of contractual rights to use the
lines of a third party. See Northeast Utilities, Holding Co. Act Release No.
25273 (Mar. 15, 1991); Centerior Energy Corp., Holding Co. Act Release No. 24073
(April 29, 1986); UNITIL Corp., Holding Co. Act Release No. 25524 (Apr. 24,
1992). The Commission has recognized that a finding that wheeling and other
forms of sharing power through reliability councils and proposed regional
transmission groups also qualify as "interconnection" under section 2(a)(29)(A)
of the Act appears to be a logical extension of prior Commission holdings. 1995
Report at 71.

               Moreover, even in the absence of the current interconnections,
the wheeling contract and the common power pool membership, the Applicants'
proposal to construct additional transmission facilities at the minimal
estimated cost of $4,400,000 would satisfy the integration requirements of the
Act. The Commission has indicated that a single integrated system exists based
solely on a planned, future interconnection, provided that such physical
interconnection is "contemplated or . . . possible within the reasonably near
future" and not just something that "might occur in the remote future, and whose
occurrence has not been foreshadowed by any facts shown in the record." In re
North American Co. and Its Subsidiaries, Holding Co. Act Release No. 4505 (Apr.
15, 1942); In re Cities Service Power & Light Corp., Holding Co. Act Release No.
5256 (Aug. 30, 1944) (integration standard met where "Derby contemplates the
construction of such interconnection facilities").

                  The transmission systems of IEC East and IEC West are not
directly connected currently. However, integration of the IEC East and IEC West
systems for purposes of accomplishing joint economic dispatch and reserve
sharing will be accommodated initially through the purchase of transmission
service from other utilities. In the long term, the integration will be made
through construction of transmission ties directly linking IEC East to IEC West.

                  The specific plan for integration of IEC East and IEC West is
as follows. During the first three years of the merger (1998-2000), IEC will
utilize firm transmission service which has already been purchased for this
purpose from other utilities to allow the needed integration. The specific
transmission purchases are 150 MW of firm from Commonwealth Edison ("ComEd") and
50 MW of firm from Dairyland Power Cooperative ("DPC"). These contracts each
began on October 1, 1997 and run through September 30, 2000. The Applicants will
report to the Commission on or before the expiration of these contracts on
future integration plans.

                  The current plan for the future integration is to construct
two transmission ties between IPC and WP&L in the year 2000. The specific
construction projects identified in the IEC merger filing were a 4-mile 69 kV
line from Hillside substation in Prairie du Chien, Wisconsin to MacGregor
substation in MacGregor, Iowa and a 3-mile 161 kV line from Nelson Dewey
substation in Cassville, Wisconsin to IPW's Turkey River substation located in
Iowa. The total capacity of these ties is estimated at 250 MW consisting of 50
MW for the 69 kV line and 200 MW for the 161 kV line.

                  The Applicants that will comprise IEC have firm transmission
agreements and anticipate that they will continue to have firm transmission
agreements until such time as the additional lines are built. Thus, if, for some
reason, the transmission ties are not constructed on time or if the future
integration between IEC East and IEC West requires more than the 250 MW of
capacity provided by the two proposed transmission ties, then IEC will continue
to purchase firm transmission service from either ComEd, DPC or Northern States
Power Company ("NSP"). Any of these three parties can currently provide the
direct transmission link between IEC East and IEC West. The capacities of the
ComEd, DPC and NSP transmission ties between IEC East and IEC West are currently
1086 MW, 464 MW and 336 MW respectively.

                  In the event that construction of the transmission
reinforcements described above has not begun within [180] days of the scheduled
termination of the currently effective transmission agreements, IEC will
initiate discussions with ComEd and DPC with the intent of extending the term of
the agreements. In the event that these discussions do not result in an
agreement to extend the term within [120] days of the scheduled termination of
the agreements, IEC will make arrangements to take short-term firm transmission
service under the then-effective open access transmission tariffs of ComEd, DPC
or NSP, or in the alternative, will submit a good faith request for long-term
firm transmission service under Section 211 of the FPA.

                  ComEd is currently interconnected with IEC East by means of a
345 kV line that runs from ComEd's Wempletown substation to the Paddock
substation in IEC East. This line has a capacity of 1086 MW, which is the
limiting segment of the IEC East-IEC West transmission path through ComEd. ComEd
is, in turn, interconnected with IEC West through two lines, rated at 345 kV and
138/161 kV, and having an aggregate capacity of 1,124 MW. The 345 kV line
connects ComEd's Quad Cities generating station with IEC East's Rock Creek
substation.

                  DPC is currently interconnected with IEC East by means of five
69 kV lines and one 138/161 kV line. The capacity of these six lines is 464 MW,
which is the limiting interface for the IEC East-IEC West transmission path
through DPC. DPC is, in turn, interconnected with IEC West by 32 separate
transmission lines, 11 of which are rated at 161 kV and the remaining 21 of
which are rated at 69 kV. The aggregate capacity of all of these transmission
lines is 1,004 MW. In addition, regional developments such as the MAPP
Independent System Operator ("ISO") and the Midwest ISO are currently underway.

         WPL has a projected native load of 2169 MW and firm off-system sales
of 251 MW for 1998. WPL owns generation capacity totaling 2350 MW. WPL has also
purchased 421 MW of firm capacity for 1998. IPW has a projected native load of
1105 MW and firm off-system sales of 179 MW for 1998. IPW owns generation
capacity totaling 1028 MW. IPW also has purchased firm capacity of 333 MW for
1998. IES's projected native load for 1998 is 1820 MW. IES has no firm
off-system sales. IES owns generation capacity totaling 1853 MW and has
purchased firm capacity for 1998 totaling 245 MW.

         Because the WPL system is not directly interconnected with either the
IES system or the IPW system, WPL has purchased a total of 200 MW of firm
transmission service between the IPW system and the WPL system for a three year
period, commencing October 1, 1997 and continuing through September 30, 2000.
150 MW of this firm transmission service was purchased from Commonwealth Edison
and the remaining 50 MW of the firm transmission service was purchased from
Dairyland Power Cooperative. The Commonwealth Edison and the Dairyland Power
Cooperative systems are directly interconnected with both the WPL and the IPW
systems. 50 MW of the total 200 MW of firm transmission service purchased by WPL
are reserved for the use of third parties. The remaining 150 MW will be used by
Interstate Energy Corporation postmerger for transferring capacity and energy
between WPL and IPW for the purposes of optimizing economic dispatch of the
generation resources of IEC as a whole and providing reliability support for
the loads in all areas of the IEC system.

         The IPW and IES systems are directly interconnected by means of a
number of transmission lines at voltage levels of 69 kV, 161 kV and 345 kV. The
cumulative tie capacity of all these interconnections is 1620 MW. This tie
capacity will likewise be used for the purposes of optimizing economic dispatch
of the generation resources of IEC as a whole and providing reliability support
for the loads in all areas of the IEC system. 

                 II.      Gas Utility System

         Section  2(a)(29)(B) of the Act defines an  "integrated  public utility
system" as applied to gas utility companies as:

                 a system  consisting of one or more gas utility companies which
                 are so located and related that  substantial  economies  may be
                 effectuated  by being operated as a single  coordinated  system
                 confined in its operation to a single area or region, in one or
                 more states,  not so large as to impair  (considering the state
                 of the art and the area or region  affected) the  advantages of
                 localized    management,    efficient   operation,    and   the
                 effectiveness  of  regulation:   provided,   that  gas  utility
                 companies  deriving  natural gas from a common source of supply
                 may be deemed to be included in a single area or region.

The  Interstate  Energy gas utility  system will meet the  standard set forth in
Section  2(a)(29)(B) and,  therefore,  will satisfy the requirements of sections
10(c)(1) and (2) and should be approved by the Commission.

         First,   both  the   Commission's   limited   precedent   and   current
technological  realities  indicate that the Interstate Energy gas utility system
will operate as a coordinated  system confined in its operation to a single area
or region  because it will derive  natural  gas from  common  sources of supply,
transportation and storage.  The gas utility operations of WP&L (including South
Beloit), Utilities and IPC will operate in a single area or region covering




                                       80
<PAGE>   85

portions of Wisconsin, Iowa, Minnesota and Illinois. See Exhibit G-5 hereto. The
Commission  has not  traditionally  required that the pipeline  facilities of an
integrated  system be physically  interconnected,(46)  and instead has looked to
such issues as from whom the  distribution  companies  within the system receive
much,  although  not all,  of their  gas  supply.(47)  The  Commission  also has
considered  obtaining gas from a common  pipeline(48)  as well as from different
pipelines  when the gas  originates  from the same gas  field in  determining  a
common  source of  supply.(49)  Since the time of most of these  decisions,  the
state of the art in the industry has developed to allow  efficient  operation of
systems whose gas supplies derive from many sources.

         Because natural gas is made up of naturally occurring elements found in
geologic  formations,  and is not a refined energy  product  produced from other
fuels,  the  natural  gas and  electricity  industries  developed  in  different
structures. The gas industry developed in three separate segments:

         FUNCTION                                  OWNERSHIP

    Production                            Independent Producers
    Transmission/Storage                  Interstate Pipelines/Storage Companies
    Distribution/Retail Sales             Local Distribution Companies (LDCs)

The  WP&L,  Utilities  and  IPC  gas  systems  will  functionally  perform  as a
coordinated  system  through the purchase of natural gas from common  sources of
supply,  delivery  through  common  interstate  pipelines (all of which are open
access transportation only pipelines under FERC Order 636) and storage of gas in
common  underground  storage  facilities.  This coordination will also result in
greater, not lesser, efficiency.

         As explained  previously under Item 1.B.4.: WP&L, Utilities and IPC all
contract  for  interstate  pipeline  transportation  and storage  services  from
Northern  Natural Gas Company and Northern Border Pipeline  Company,  and two of
the three companies contract for transportation and/or storage services from ANR
Pipeline  Company,  LG&E/Llano Inc. and Natural Gas Pipeline Company of America.
In addition,  all three companies procure natural gas supplies from producers in
the Gulf Coast and Canadian regions. Less significant volumes are purchased from
non-common supply areas such as the Texas/Oklahoma and Permian Basin regions.

         WP&L,  Utilities and IPC all use a "supply grid" approach to gas supply
procurement  described in more detail in Item 1.B.4.  Integrated WP&L, Utilities
and IPC gas operations  would present  opportunities  to use an expanded  supply
grid and more consolidated gas supply procurement to increase  competition among
suppliers,  transporters and storage  providers to capture  approximately  $23.6
million in delivered  gas cost savings.  Integrated  gas  operations  could also
offer  opportunities  for  more  efficient   utilization  of  IPC  peak  shaving
operations  and more  efficient  reserve  margins.  With the  cooperation of the
common  pipeline  interconnections,  the ability to engage in swap  transactions
will also exist.





                                       81
<PAGE>   86


         Finally, the system will not be so large as to impair the advantages of
localized  management or the  effectiveness of regulation.  As set forth in Item
3.A.2.a.(i).,  localized management will be preserved.  The three utilities will
maintain  headquarters in Madison,  Cedar Rapids and Dubuque,  and local matters
will be handled by  several  regional  offices.  Management  will,  accordingly,
remain close to the gas operations,  thereby  preserving the advantages of local
management.

         As also set forth in Item  3.A.2.a.i.,  from a  regulatory  standpoint,
there will be no  impairment of regulatory  effectiveness.  The same  regulators
currently  overseeing  these gas operations  will continue to have  jurisdiction
after   the    Transaction.    Several    states    are    already    regulating
multi-jurisdictional  gas utilities since other gas utilities  currently operate
in some of the states to be served by Interstate  Energy. IPC currently operates
gas utilities in multiple states.

         For all of these reasons,  the  post-Transaction gas operations satisfy
the integration requirements of Section 2(A)(29)(B).

         3.      Section 10(f)

         Section 10(f) provides that:

         The  Commission  shall  not  approve  any  acquisition  as to  which an
         application  is made  under  this  section  unless  it  appears  to the
         satisfaction  of the  Commission  that such  State laws as may apply in
         respect to such acquisition  have been complied with,  except where the
         Commission  finds  that  compliance  with  such  State  laws  would  be
         detrimental to the carrying out of the provisions of section 11.

          As  described  in  Item  4  of  this  Application/Declaration,  and
as evidenced  by the  Orders of  the  FERC,  PSCW,  MPUC, ICC and  IUB, all
relating to the Transaction, Interstate Energy intends to comply with all
applicable  state laws related to the proposed transaction.
         4.      Other Applicable Provisions - Sections 6, 7, 9(a)(1) and 12

         As  noted in Items  1.D.  and  1.E.,  WPLH,  IES and IPC have  dividend
reinvestment  plans,  employee benefit plans and 401(k) savings plans, which may
require the issuance,  or  acquisition in  open-market  transactions,  of common
stock. The dividend  reinvestment  plans of IES and IPC will be terminated as of
the date of consummation of the Transaction.  The dividend  reinvestment plan of
WPLH will remain  (subject to certain  proposed  modifications)  as the dividend
reinvestment plan of Interstate Energy. In addition, the employee benefits plans
(including  the 401(k)  plans) of IES and IPC will be amended to provide for the
acquisition or issuance of shares of Interstate  Energy Common Stock in place of
IES Common Stock or IPC Common Stock, as the case may be. Additional information
concerning the  anticipated  terms of the dividend  reinvestment  plan,  benefit
plans and 401(k) plans is set forth





                                       82
<PAGE>   87

in Items I.D.1 - .3. To provide for the operation of these  existing and amended
or  replacement  plans  after  the  consummation  of  the  Transaction  and  the
registration  of  Interstate  Energy as a holding  company  under the Act, it is
estimated  that up to 11 million  shares of  Interstate  Energy Common Stock may
need to be  issued  and/or  acquired  in  open-market  or  privately  negotiated
transactions through December 31, 2001.

         As required by Section 6 of the Act, the issuance by Interstate  Energy
of  shares  of its  common  stock  pursuant  to such  plans  and to  effect  the
Transaction  will  comply  with the  standards  of  Section  7 of the Act.  With
reference to Sections 7(c) and 7(d) of the Act,  Interstate  Energy Common Stock
will have a par value of $0.01  per  share,  will be  Interstate  Energy's  only
outstanding  voting  security  and  will not be  preferred  as to  dividends  or
distributions  over any other security of Interstate  Energy.  Interstate Energy
Common Stock is reasonably  adapted to  Interstate  Energy's  capital  structure
(common stock being the cornerstone of a registered  holding  company's  capital
structure).

         Finally,  applicants request authorization under Section 9(a)(1) of the
Act for  Interstate  Hold to acquire  all of the issued and  outstanding  common
stock  of  all the diversified businesses discussed in Exhibit M-5. Applicants
believe that  the  reorganization  of the  non-utility  businesses  described
above  as subsidiaries  of Interstate  Hold will be beneficial to ratepayers by
continuing to insulate the  operating  utilities  from the results of operations
of these non-utility business entities.

B.       Intra-system Financing

         WPLH has entered into agreements with its non-utility subsidiaries HDC,
HPI and Capital Square to provide  inter-company loans and other credit support.
Loans made by WPLH to these  non-utility  subsidiaries  are used to finance  the
specific  activities of the  subsidiaries  or may be used to fund  activities of
entities in which the subsidiaries have an equity interest.  Intercompany  loans
to subsidiaries bear interest at an intercompany  borrowing rate which is set at
slightly above the forecasted WPLH weighted average cost of capital for the year
and is  reviewed  and reset,  if  necessary,  annually.  The  increase  over the
weighted average cost of capital is intended to cover the costs of administering
the loan agreements with subsidiaries. Intercompany loans are payable on demand.
As of May 31, 1996, WPLH had loans outstanding to HDC, HPI and Capital Square of
$17.0 million, $11.2 million, and $10.4 million, respectively.

         To provide funds for these loans,  WPLH has adopted an internal banking
arrangement pursuant to which any excess funds from non-utility subsidiaries are
deposited with WPLH and used to fund loans to other non-utility subsidiaries and
WPLH's own operations. Interest is paid on deposits from subsidiaries maintained
by WPLH at a rate equal to the intercompany borrowing rate described above.





                                       83
<PAGE>   88

         WPLH also  acquires  funds from  loans  under  committed  bank lines of
credit,  which totalled  $45,000,000  as of May 31, 1996, and through  long-term
private placements of notes. WPLH periodically issues its notes, with maturities
generally  ranging from 5 to 10 years, in private  placement  transactions  with
unaffiliated  third parties.  Such funds are generally used to retire short-term
debt  incurred  to  finance  loans by WPLH to  non-utility  subsidiaries,  or to
finance specific activities of WPLH or its non-utility subsidiaries.

         In addition to making loans to non-utility subsidiaries,  WPLH has also
guaranteed the mortgage debt of RMT, with an original  principal balance of $7.4
million,  and  provided  credit  guarantees  on behalf of HES.  WPLH  guarantees
payment of all  obligations  incurred by HES in  connection  with various  power
purchase transactions.

         In  connection  with the  issuance  of  mortgage  bonds  under a master
indenture to finance affordable housing projects by various subsidiaries of HPI,
WPLH  entered  into  a  support   agreement  under  which  WPLH  guarantees  the
maintenance of various debt service reserve funds. Under this support agreement,
if the  various  properties  do not  provide  adequate  cash flow to cover  debt
service,  WPLH is obligated to make certain payments into the reserve funds. The
obligation to make such payments irrevocably  decreases as the reserve funds are
funded to specified levels.

         In connection  with a $40,000,000  revolving  credit facility (the "HCC
Facility")  provided  by a group of banks to HCC,  WPLH,  HDC,  HPI and  Capital
Square have entered into support  agreements with the banks.  The purpose of the
HCC  Facility  is to  provide  funds  for  construction  and  bridge  loans  for
affordable housing projects. Loans from the revolving credit facility are repaid
from  the  proceeds  of  permanent  mortgage  financing  when the  projects  are
completed. Under WPLH's support agreement, WPLH must (i) provide lines of credit
to HDC,  HPI and Capital  Square of $10 million,  $25 million,  and $10 million,
respectively,  (ii)  maintain  HDC's  tangible  net  worth at not less  than $25
million, and (iii) maintain WPLH's quarterly pre-tax interest coverage ratio and
its  consolidated  leverage ratio within  specified  limits.  In the case of the
lines of credit provided by WPLH to HPI and Capital  Square,  $15 million and $5
million,  respectively,  are reserved solely to fund obligations of the entities
under their respective support agreements.

         In  connection  with the HCC  Facility,  HPI has entered into a support
agreement  with the banks which  requires  HPI to (i) continue as manager of HCC
unless removed for cause, (ii) maintain quarterly interest coverage ratio within
specified limits,  (iii) maintain HPI's $25 million line of credit with WPLH and
(iv)  provide HCC with a $15  million  line of credit  under a revolving  credit
agreement.

         In  connection  with the HCC  Facility,  HDC has entered into a support
agreement  with the banks  which  requires  HDC to (i)  maintain  at least a 51%
ownership interest in HPI and Capital Square, (ii) maintain HDC's line of credit
with WPLH and (iii) provide an irrevocable and unconditional  guaranty of 20% of
the principal amount of any outstanding loans from the banks to HCC.





                                       84
<PAGE>   89


         In connection with the HCC Facility,  Capital Square has entered into a
support agreement with the banks which requires Capital Square to (i) repurchase
certain  loans from the banks or from HCC and (ii)  maintain  its line of credit
with WPLH.

         To  support  the  business  activities  of the  entities  in which they
invest, HPI and HDC make loans and/or extend lines of credit to their respective
subsidiaries or entities in which they have substantial  investments.  As of May
31, 1996,  HPI and HDC had made loans to affiliates  totaling  3.655 million and
16.435 million, respectively.

         IES  maintains  a money pool for the benefit of itself,  Utilities  and
Diversified.  The money pool consists of funds available for investment by these
companies.  The money pool  funds can be  borrowed  to meet the daily  financing
requirements,  thereby  minimizing the need for external  short-term  borrowing.
Promissory notes stating the terms of the agreement exist between IES, Utilities
and Diversified.

         Investments  in  the  money  pool  shall  earn  interest  at  the  rate
determined by IES cash  management  personnel on the first  business day of each
month.  The rate of interest is based upon the  investments  selected  for daily
cash liquidity. The rate of interest on money pool loans shall be the same as on
money pool investments.

         Diversified  also has a variable  rate  credit  facility  that  extends
through  November 9, 1998, with a one-year  extension  available to Diversified.
The facility also serves as a stand-by  agreement for  Diversified's  commercial
paper program.  The agreement provides for a combined maximum of $150 million of
borrowings under the agreement and commercial paper to be outstanding at any one
time.  Interest rates and maturities are set at the time of borrowing for direct
borrowings  under the  agreement  and for  issuances of  commercial  paper.  The
interest rate options are based upon quoted market rates and the  maturities are
less than one year.  This  agreement  is the main source of debt  financing  for
Diversified.

         Diversified  maintains  a system of  advances  between  itself  and its
subsidiaries  to supplement  their internal cash flows.  Long-term  financing of
Diversified's  subsidiaries  is  infused  into the  subsidiaries  as  equity  by
Diversified.

         Applicants  hereby request that the Commission  approve the continuance
of all  outstanding  and committed  intercompany  loans,  guarantees and support
agreements.

C.       Interstate Services

         As described in Item 1.B.1.a.iii,  Interstate Services may provide WP&L
(including South Beloit),  Utilities and IPC, pursuant to the Services Agreement
and the Coordination Agreement,  and the non-utility companies of the Interstate
Energy system (including  Interstate Hold), pursuant to the Non-Utility Services
Agreement,  with a variety of  administrative,  management and support services.
These services may include, without limitation, services relating to information
systems, meters, transportation, electric system





                                       85
<PAGE>   90

maintenance,   marketing  and  customer  relations,  electric  transmission  and
distribution  engineering and construction,  power engineering and construction,
human resources, materials management,  facilities,  accounting, power planning,
public  affairs,  legal,  rates,  finance,  right  of  way,  internal  auditing,
environmental  affairs,  fuels,  investor relations,  planning,  executive,  gas
system   maintenance,   gas  transmission   and  distribution   engineering  and
construction,  gas  acquisition  and dispatch,  gas production  engineering  and
construction,  steam system  maintenance,  steam  distribution  engineering  and
construction,  steam supply engineering and construction,  steam planning, water
system  maintenance,  water  distribution  engineering and  construction,  water
supply engineering and construction,  and water planning. In accordance with the
Service  Agreement,  services  provided by Interstate  Services will be directly
assigned  or  allocated  by  activity,  project,  program,  work  order or other
appropriate  basis.  To  accomplish  this  objective,  employees  of  Interstate
Services  will record  transactions  utilizing  the  existing  data  capture and
accounting systems of each client company.  Costs of Interstate Services will be
accumulated  in  accounts  of  Interstate  Services  and  directly  assigned  or
allocated to the  appropriate  client company in accordance  with the guidelines
set forth in the Service Agreement.  WPLH, IES and IPC are currently  developing
the system and procedures necessary to implement the Service Agreement.

         The Service Agreements give the system companies the explicit right, at
their sole discretion, to discontinue taking services from Interstate Services
under any circumstances where a company other than Interstate Services can
provide fully comparable quality services at a price that is lower than the
price charged by Interstate Services. Also, prior to filing any amendments to a
Service Agreement with the Commission, the parties to the Service Agreement must
file with the applicable state regulatory commissions, pursuant to law or
stipulation, a copy of such amendments. Under the Service Agreements, in the
event that a state commission does not object to an amendment within forty five
days of its filing with the state commission or issue a letter within that time
requiring that the amendment be held in abeyance until that state commission
completes its review, the parties to the Service Agreement will consider the
state commission to have acquiesced to the amendment.

         The operation of Interstate  Services will allow  Interstate  Energy to
capture economies of scale from the centralization of administrative and general
services to be provided to system companies. Since the cost of such services are
considered  in rate  cases,  the  benefits  realized  as a result of  Interstate
Services  will  accrue  to  Interstate  Energy's  ratepayers.   Virtually  every
registered  holding  company  has  one  or  more  subsidiary  service  companies
performing many of the same functions that Interstate Services will perform. The
utilization of Interstate Services as a service company subsidiary of Interstate
Energy  is in the  public  interest,  will not  unduly  complicate  the  capital
structure of Interstate  Energy and will not cause the Interstate  Energy system
to violate any other provision of the Act.

         It is anticipated that Interstate Services will be staffed primarily by
transferring  personnel from the current  employee  rosters of WP&L, IES and IPC
and their  subsidiaries.  Interstate  Services'  accounting and cost  allocation
methods  and  procedures  are  structured  so as to comply  with the  Commission
standards for service  companies in registered  holding-company  systems and are
described in Exhibit N hereto.  Interstate Services' billing system will use the
"Uniform System of Accounts for Mutual Service Companies and Subsidiary  Service
Companies"  established by the  Commission  for service  companies of registered
holding-company systems.

         As compensation for services,  the Service  Agreement  provides for the
client  companies to: "pay to [Interstate  Services] all costs which  reasonably
can be identified  and related to particular  services  performed by [Interstate
Services] for or on behalf of" such client company.  Where more than one company
is involved in or has received  benefits from a service  performed,  the Service
Agreement  provides  that "costs of such  service  will be directly  assigned or
allocated.  . .between or among such [c]lient  [c]ompanies on a basis reasonably
related to the  service  performed  to the extent  reasonably  practicable,"  in
accordance with the methods set forth





                                       86
<PAGE>   91

in Appendix A to the Service Agreement.  Thus, charges for all services provided
by Interstate  Services to affiliated  utility companies will be on an "at cost"
basis as determined  under Rules 90 and 91 of the Act. The  Non-Utility  Service
Agreement contains provisions similar to those of the Service Agreement,  except
that the Non-Utility Service Agreement also permits charges for certain services
to be at fair market value to the extent  permitted  under the Act or authorized
by the Commission.  Thus, except for the requested  exceptions  discussed below,
services  provided by Interstate  Services to  non-utility  associate  companies
pursuant to the  Non-Utility  Service  Agreement  will also be charged on an "at
cost" basis as determined under Rules 90 and 91 of the Act.

         Section 13(b) of the Act allows the Commission to exempt  transactions,
by rule, regulation or order, from the provisions of Section 13(b) and the rules
promulgated thereunder if such transactions:

                 (1) are with  any  associate  company  which  does not  derive,
         directly or  indirectly,  any material  part of its income from sources
         within the  United  States  and which is not a public  utility  company
         operating within the United States, or

                 (2)      involve special or unusual circumstances or are not
         in the ordinary course of business.

The  Commission  has utilized  this  exemptive  power in the past under  certain
circumstances(50)   and  recently  with  some   frequency  to  generally   allow
non-utility  subsidiaries of registered holding companies to provide services to
certain FUCOs at market-based  rates.(51) In addition,  the Division recommended
in the 1995  Report  that "the SEC should  also  issue  exemptive  orders  under
Section 13 allowing  more  non-utility  subsidiaries  to charge  market rates to
non-utility affiliates."(52) The Commission's principal concern under Section 13
of the Act is to protect the utility  companies in a holding company system from
abusive cross-subsidization transactions with affiliates.  Exemptions from Rules
90 and 91 for  purely  non-utility  transactions  will not  interfere  with this
mandate  because  all  services  to  utility  subsidiaries  will  be at  cost in
accordance  with Rules 90 and 91. In addition,  exemptions  from Rules 90 and 91
will benefit the holding  company  system by allowing it to offer  competitively
priced services based on market  considerations.  Pursuant to Section  13(b)(1),
the Commission has adopted Rule 83(a),  which provides that a subsidiary service
company,  "which  subsidiary is or is about to become engaged in the performance
of any service,  sales, or construction contract for any associate company which
does not derive,  directly  or  indirectly,  a material  part of its income from
sources  within the  United  States  and which is not a  public-utility  company
operating  within the United States,  may ...[obtain  an]  exemption...from  the
standards  established by Section 13(b) of the Act, and the [Commission's] rules
and  regulations  promulgated  thereunder,  relating to the  performance  of any
service,  sales or construction  contract for such associate  companies."





                                       87
<PAGE>   92
         The Applicants hereby request on behalf of IEC an exemption under
section 13 of the Act and rules 90 and 91 thereunder from the at-cost
requirements in connection with the provision of goods and services, including
operation and maintenance services, at fair market prices by Interstate Services
to associate foreign utility companies ("FUCO's"), provided that no such
services will be rendered to an associate FUCO unless the FUCO derives no part
of its income, directly or indirectly, from the generation, transmission or
distribution of electric energy for sale within the United States. (53)
         No material change in the organization of Interstate Services, the type
and character of the companies to be serviced,  the methods of allocating  costs
to  associate  companies,  or in the scope or  character  of the  services to be
rendered  subject  to Section 13 of the Act,  or any rule,  regulation  or order
thereunder,  shall be made unless and until Interstate Services shall first have
given the Commission written notice of the proposed change not less than 60 days
prior to the proposed  effectiveness of any such change. If, upon the receipt of
any such notice,  the Commission  shall notify  Interstate  Services  within the
60-day  period  that a question  exists as to  whether  the  proposed  change is
consistent  with  the  provisions  of  Section  13 of the Act,  or of any  rule,
regulation  or order  thereunder,  then the  proposed  change  shall not  become
effective  unless  and until  Interstate  Services  shall  have  filed  with the
Commission an appropriate  declaration  regarding  such proposed  change and the
Commission shall have permitted such declaration to become effective.

         Any modification of allocation factors which requires filing under
60-day letter procedures based on existing Commission guidelines will be filed
on a timely basis. The current guidelines require approval if the change will
cause the lesser of $50,000 or a 5% change in the allocation of cost between
companies. These guidelines are subject to change.

         The applicants  believe that the Service  Agreement and the Non-Utility
Service  Agreement are structured so as to comply with Section 13 of the Act and
the Commission's rules and regulations thereunder.

         Rule 88:  Rule 88(b) provides that "[a] finding by the Commission that
a subsidiary company of a registered holding company . . . is so organized and
conducted or to be conducted, as to meet the requirements of Section 13(b) of
the Act with respect to reasonable assurance of efficient and economical
performance of services or construction or sale of goods for the benefit of
associate companies, at cost fairly and equitably allocated among them (or as
permitted by [Rule] 90), will be made only pursuant to a declaration filed with
the Commission on Form U-13-1, as specified in the instructions for that form,
by such company or the persons proposing to organize it."  Notwithstanding the
foregoing language, the Commission has on at least two recent occasions made
findings under Section 13(b) based on information set forth in an
Application/Declaration on Form U-1, without requiring the formal filing of a
Form U-13-1.  See CINergy Corp., Holding Co. Act Release No.  26146 (Oct. 21,
1994); UNITIL Corp., Holding Co. Act Release No. 25524 (April 24, 1992).  In
this Application/Declaration, applicants have submitted substantially the same
applicable information as would have been submitted in a Form U-13-1.

         Accordingly,  it is  submitted  that it is  appropriate  to  find  that
Interstate  Services is so organized and its business will be so conducted as to
meet the  requirements of Section 13(b), and that the filing of a Form U-13-1 is
unnecessary,  or,  alternatively,  that this  Application/Declaration  should be
deemed to constitute a filing on Form U-13-1 for purposes of Rule 88.

         Services will be the central control point for all services provided by
Services or through Services and during the interim before personnel are moved
into Services, from one affiliated company to another. Services will maintain
policies and procedures to accurately account for services requested by
affiliates, the cost of providing such services and, if necessary, the cost to
Services of procuring such services. This system of policies and procedures will
be maintained on line for all to use. IEC will have a separate account with
Services for executive functions that are not related to utility affairs. This
account will include charges that are appropriately included in it alone and
which, under the executive allocation formula, will be allocated to the account.
Such functions will include, for example, strategic planning by executives of
merger and acquisition activities.

         Included as Exhibits D-6 and D-7 are the updated Utility and
Non-Utility Service Agreements, respectively, that have been revised pursuant to
the order of the PSCW. The PSCW ordered two basic changes to the Services
Agreements. First, the Applicants added language to the Service Agreements to
give WP&L the right to discontinue taking services from Services if the cost for
those particular services exceeds the fair market value for the services (please
see discussion below). Second, language was added to require the Applicants,
prior to making any amendment to the Service Agreements, to file the amendment
for approval with each of the state commissions with jurisdiction over the
holding company's activities. Under this provision, if any of the state
commissions does not object to the amendment or issue a letter requiring that
the amendment be held in abeyance until the state commission issuing the letter
completes its review, the Applicants will be able to file the amendment with the
Commission. Also, under the Service Agreements, prior to the filing of any
amendment relating to the cost allocation methods to be utilized by Services,
Services and each of the other parties to the Service Agreements would have to
approve the change.

D.      Other Services

         In addition to the  services  to be  provided by  Interstate  Services,
WP&L,  South  Beloit,  Utilities  and IPC may, as  permitted  by Rule  87(a)(3),
provide  one  another  with  certain   services   incidental  to  their  utility
businesses,  such  as  meter  reading,  materials  management,  gas  purchasing,
transportation,  and services of linemen and gas trouble  crews.  Such  services
will be provided at cost in  accordance  with the  standards  of the Act and the
Commission's rules and regulations thereunder.

         IES has subsidiaries that may provide services (including operation and
maintenance) and sell goods to entities that will qualify as FUCOs following the
Transaction. The applicants request that the Commission permit such subsidiaries
to enter into such transactions  without  compliance with the at cost provisions
of Section 13(b) and the rules and regulations thereunder.

         The Commission has  previously  granted  authority to provide goods and
services  to  existing  and future  FUCOs  without  compliance  with the at cost
provisions to affiliates of registered holding companies that fall within one of
the following categories:

                 1)       the project is a FUCO or an EWG that derives no part
         of its income, directly or indirectly, from the generation,
         transmission or distribution of electric energy for sale within the
         United States;

                 2)       the project is an EWG that sells electricity at
         market-based rates which have been approved by the FERC or the
         appropriate state public utility commission, provided that the
         purchaser is not an Excepted Company;(54)


                 3) the project is a QF that sells  electricity  exclusively  at
         rates  negotiated  at  arms's  length  to one  or  more  industrial  or
         commercial  customers purchasing such electricity for their use and not
         for resale,  or to an electric  utility  company other than an Excepted
         Company; or

                 4) the  project  is an EWG or a QF that  sells  electricity  at
         rates based upon its cost of service,  as approved by FERC or any state
         public  utility  commission  having  jurisdiction,  provided  that  the
         purchaser is not an Excepted Company.

Entergy Corp., Holding Co. Act Release No. 26322 (June 30, 1995).

         In the Entergy  order quoted  above,  the  Commission  granted  Entergy
Enterprises,  a  wholly  owned  subsidiary  of  Entergy,  authority  to  provide
consulting services to associate companies,  including FUCOs, and operations and
management services, either directly or through  newly-established  subsidiaries
of Entergy or Entergy Enterprises, to associate





                                       89
<PAGE>   94

companies,  including  FUCOs,  without  complying with the at cost provisions of
Section 13(b) and the rules and regulations thereunder.

         In CINergy  Corp.,  Holding Co. Act Release No.  26376  (September  21,
1995), the Commission authorized CINergy and CINergy Investments, a wholly-owned
subsidiary of CINergy, to acquire securities of new special purpose subsidiaries
("NSPSs")  and to  make  additional  investments  in  existing  special  purpose
subsidiaries ("ESPSs").  ESPSs and NSPSs acquire, own or hold securities of, and
provide  services to, FUCOs.  The Commission also authorized ESPSs and NSPSs and
CINergy Services to provide  administrative,  management and support services to
other ESPSs and NSPSs and their subsidiaries  without complying with the at cost
provisions of Section 13(b) and the rules and regulations  thereunder.  See also
General Public Utilities  Corp.,  Holding Co. Act Release No. 26457 (January 18,
1996).  (Pending completion of the record, the Commission reserved  jurisdiction
over  whether   subsidiaries  formed  to  directly  or  indirectly  acquire  the
securities  of FUCOs could sell goods and  services to associate  FUCOs  without
complying  with the at cost  provisions  of  Section  13(b)  and the  rules  and
regulations thereunder.)

         The  applicants  request  that the  Commission  permit the  present and
future subsidiaries of Applicants,  which will become subsidiaries of Interstate
Energy,  to provide  services or sell goods to FUCOs and to  entities  that will
qualify as FUCOs following the  Transaction to the same extent  permitted by the
Commission in the above-cited orders.

         Other than permitted "incidental services," the services provided by
WP&L, South Beloit, Utilities and IPC will only be provided in the interim
period between the consummation of the merger and the completion of the transfer
of necessary employees from the companies to Services. The completion of all of
the employee transfers, however, cannot be accomplished simultaneously. All
services will nevertheless still be provided through Services. Employees will
simply be secunded from the appropriate companies to Services to provide needed
services; these services will be billed at cost to Services by the companies and
will be accounted for on Services' accounts. Ultimately, after the transition of
employees is completed, all of these services will be performed directly by
Services through its own employees.

Item 4.  Regulatory Approvals

         Set  forth  below is a summary  of the  regulatory  approvals  that the
applicants have obtained or expect to obtain in connection with the Transaction.

A.       Antitrust

         The HSR Act and the  rules  and  regulations  thereunder  provide  that
certain  transactions  (including the Transaction) may not be consummated  until
certain  information has been submitted to the DOJ and FTC and specified HSR Act
waiting period  requirements  have been satisfied. Applicants have fully 
satisfied the requirements of the HSR Act and are free to consummate the 
merger with no further obligations thereunder. 
         The Applicants fully satisfied the requirements under the HSR Act on 
July 7, 1996. However, because the Applicants did not consummate the Transaction
within one year of that date, the Applicants were obliged to re-notify the DOJ
and FTC of the proposed Transaction. The Applicants resubmitted the necessary
filings under the HSR Act on September 3, 1997. The HSR Act imposes a 30-day
waiting period for the consummation of each merger comprising the Transaction
subject to the HSR Act's prenotification requirement. The Applicants, however,
requested and were granted early termination of that waiting period by the FTC
on September 12, 1997.

B.       Federal Power Act

         Section 203 of the Federal  Power Act of 1935, as amended (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.
On March 1, 1996,  WP&L, HES, South Beloit,  IPC,  Utilities and IEA submitted a
joint  application to the FERC for approval of the Transaction under Section 203
and Part 33 of the FERC's  regulations.  This filing was supplemented on June 5,
1996.  On March 1,  1996,  WP&L,  South  Beloit,  IPC and  Utilities  also filed
transmission  tariffs with FERC offering open access  transmission  service over
their combined facilities.
         The Administrative Law Judge presiding over the FERC proceeding issued
his Initial Decision on Rate and Merger Issues in Docket Nos. EC96-13-000,
ER96-1236-000 and ER96-2560-000 approving the Transaction, subject to
conditions, on July 3, 1997. The Initial FERC Decision was subject to FERC
review; the subsequent FERC order, Opinion No. 419, approving the transaction,
was issued on November 12, 1997.
         
         The FERC's competitive analysis in Opinion No. 419, issued on November
12, 1997, focused primarily on the effect of the merger on the control of
transfer capability into WUMS and the potential that IEC would use any such
enhanced control to reduce the ability of other competing utilities from
accessing lower-cost power from outside of WUS. In response to this concern, the
FERC agreed with the conclusion of the Administrative Law Judge in the Initial
Decision on Rate and Merger Issues in Docket Nos. EC96-13-000, ER96-1236-000 and
ER96-2560-000, issued on July 3, 1997, that the Competition Stipulation
("Stipulation") entered into by the Applicants and FERC trial staff would
sufficiently mitigate any adverse competitive effects that may arise as a result
of the merger. One of the points in the Stipulation required IEC to delay the
construction of the two proposed transmission ties between IEC East and IEC West
until it is determined that the ties, either by themselves or in combination
with other transmission facility additions, will increase the simultasneous
import capability into WUMS by a minimum of 400MW over existing capability. The
Applicants proposed that IEC would make eight specified transmission system
improvements to increase simultaneous transfer capability into WUMS by
400-600MW. The cost of the improvements will be approximately $4 million. The
determination of whether the enhanced capability goal has been met shall be
conducted, under FERC Opinion No. 419, by a Facilities Study Group described in
the FERC Opinion. In addition, the Applicants agreed that they would not at any
time claim more than 250MW of capacity of the 400 MW of additional capacity.
FERC stated that the net effect of the Applicants' commitments would be at least
an additional 150MW of transfer capability into WUMS and that such an additional
capability mitigates any competitive concerns. Thus, the FERC did not prohibit
the construction of the tie-lines, but merely delayed the start of the
construction until they were made part of an overall design plan to provide
additional simultaneous transfer capability into WUMS.



                                       91

<PAGE>   96

         WP&L, IPC and Utilities plan to file with FERC,  under Sections 203 and
205 of the Federal Power Act, a coordination  agreement  providing for the joint
operation of the electric  facilities,  including  certain exchanges of capacity
and energy among the three  companies.  In Order 888, FERC has  determined  that
each public utility must provide comparable, open access transmission service to
all potential  wholesale users of its transmission  system.  WP&L (together with
South  Beloit),  IPC and Utilities have filed open access tariffs to comply with
the  requirements of Order 888. A tariff providing for service over the combined
facilities of WP&L,  South Beloit,  IPC and Utilities is expected to be filed in
the near future to supersede the March 1, 1996 tariff filing.

C.       Atomic Energy Act

         Utilities holds an NRC operating license authorizing  Utilities to hold
an ownership  interest  in the Duane  Arnold  Energy  Center and to operate the
facility.  WP&L also holds an NRC operating license  authorizing WP&L to hold an
ownership  interest in the  Kewaunee  nuclear  generating  facility.  The Atomic
Energy Act  provides  that no such NRC license or any rights  thereunder  may be
transferred  or in any manner  disposed  of,  directly  or  indirectly,  through
transfer of control of such license to any person 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,  Utilities  and WP&L have
reviewed approvals from the NRC to reflect the fact that Utilities and WP&L will
continue to hold their  existing  NRC  licenses  as  operating  company
subsidiaries  of Interstate Energy upon consummation of the Transaction. The NRC
approved the Transaction relative to the Duane Arnold Energy Center on August
28, 1997. Pursuant to the Order, parties had until October 6, 1997 to request a
hearing on the Order; no such hearing was requested.

D.       State Public Utility Regulation

         The PSCW, IUB, MPUC and ICC have  jurisdiction  over various aspects of
the  Transaction.  Reference is made to Exhibits O-1 through 0-4 with respect to
the applications filed or to be filed before such commissions.

         Utilities and IPC possess municipal franchise and environmental permits
and  licenses  that may  need to be  renewed  or  replaced  as a  result  of the
Transaction if the  Reincorporation  Mergers are affected.  Utilities and IPC do
not anticipate any difficulties in obtaining such renewals or replacements.
         The MPUC approved the Transaction in Minnesota Public Utilities
Commission Opinion and Order at Docket No. E, 6-100/PA-96- 184 (March 24, 1997).
The ICC approved the Transaction in Illinois Commerce Commission Opinion and
Order in Matter No. 96-0122 (May 7, 1997) (filed as Exhibits O-3- (a) and
O-4-(a)). The IUB approved the Transaction at Docket No. SPU-96-6 on September
26, 1997 (filed as Exhibit 0-5-(a)). The PSCW, in an Order relating to Docket
No. 6680-UM-100, effective November 6, 1997, approved the merger subject to
conditions (filed as Exhibit 0-6-(a)).

         Pursuant to the Applicants' agreement with the PSCW and in response to
the PSCW Order effective November 6, 1997, the Applicants hereby request that
the Commission include in any order approving IEC as a registered holding
company:

         Approval of the Application in no way precludes the Public Service
         Commission of Wisconsin, the Iowa Utilities Board, the Minnesota
         Utility Commission, the Illinois Commerce Commission or any other state
         regulatory authority from scrutinizing and disallowing the pass through
         of costs and rates for services rendered to customers of the client
         companies. It is the SEC's intention that each state commission having
         jurisdiction over a client company will retain the right to review and
         disallow cost of services provided to a client company by Interstate
         Services, Inc., that may be subject to recovery in rates.

         In its Order relating to Docket No. 6680-UM-100, effective November 6,
1997, the PSCW recognized that a conflict could arise between it and the
Commission if it applied the usual PSCW pricing standards for transactions
between Services and the utility operating companies such as WP&L. The PSCW
acknowledged that the Commission requires that such services be billed "at
cost," in contrast to its own pricing standards, which generally require billing
at the lower of at cost or "fair market value." In order to prevent a conflict
between the provisions but maintain its policy of trying to "protect ratepayers
from paying higher than market prices," the PSCW required that the Applicants
add language to the Service Agreements that gives WP&L the explicit right to
discontinue taking services from Services any time the cost for such services
exceeds the fair market value for the services. Thus, the PSCW reached a balance
between its pricing standards and those of the Commission because (i) it did not
require Services to provide services to WP&L at a price level that would deviate
from the at cost price standards of the Commission, but (ii) did require WP&L to
look elsewhere for services when the price of the services provided by Services
exceeded the fair market value for those services.

         Except as set forth above,  no other state or local  regulatory body or
agency  and no other  federal  commission  or agency has  jurisdiction  over the
transactions proposed herein.

Item 5.  Procedure

                  The Commission is respectfully requested to enter an order not
later than February 20, 1998 granting and permitting this
Application/Declaration to become effective.

                  It is submitted that a recommended decision by a hearing or
other responsible officer of the Commission is not needed for approval of the
proposed Transaction. The Division of Investment Management may assist in the
preparation of the Commission's decision. There should be no waiting period
between the issuance of the Commission's order and the date on which it is to
become effective.

Item 7.  Information as to Environmental Effects

         The  Transaction   neither   involves  a  "major  federal  action"  nor
"significantly  affects the quality of the human environment" as those terms are
used in Section  102(2)(C) of the National  Environmental  Policy Act, 42 U.S.C.
Sec. 4321 et seq. The only federal actions related to the Transaction pertain to
the Commission's  declaration of the effectiveness of Registration  Statement of
WPLH and IPC on Form S-4, the approvals and actions  described  under Item 4 and
Commission  approval  of  this  Application/Declaration.   Consummation  of  the
Transaction  will not result in changes in the operations of WP&L,  Utilities or
IPC that  would  have any  impact  on the  environment.  No  federal  agency  is
preparing an environmental impact statement with respect to this matter.

1.       Utilities and IPC are already directly physically interconnected
         through numerous transmission lines that they own, including three 161
         KV lines and the East 345 KV Line which runs from Minneapolis/St. Paul
         to St. Louis in which Utilities and IPC participate along with other
         neighboring utilities.

2.       WP&L and South Beloit are already directly physically interconnected
         by two 69 KV transmission lines.

3.       The Applicants have entered into a firm contract for the transmission
         of up to 200 MW of power with ComEd and DPC for a three year period
         that commenced on October 1, 1997.

4.       WP&L, Utilities and IPC are members of the MAPP Regional Transmission
         Committee ("RTC") and the MAPP Power and Energy Marketing Committee
         ("PEM"). Membership in the RTC joins the transmission resources of all
         three Applicants to the MAPP transmission pool and permits
         participation in the MAPP transmission pool by the Applicants through
         the use of MAPP Schedule F. Membership in PEM allows the Applicants to
         engage in capacity and energy transactions using MAPP Schedule K.

5.       The transmission lines proposed to be constructed include a 69 KV tie-
         line between Prairie du Chien, Wisconsin and MacGregor, Iowa and a 161
         KV line connecting WP&L's Nelson Dewey generating plant on the east
         side of the Mississippi River to IPC's Turkey River substation on the
         west side of the Mississippi River.

6.       See endnote 3. Pursuant to the competitive stipulation, Applicants
         agreed to offer 50 MW of their transmission rights to WUMS loads on a
         first come, first served basis.

7.       See endnote 5.

8.       See, e.g., CINergy Corp., Holding Co. Act Release No. 26146 (Oct. 21,
         1994).

9.       Letter of the Division of Investment Management to the Securities and
         Exchange Commission, 1995 Report.

10.      E.g., the reduced regulatory burdens associated with routine
         financings.  1995 Report at 50.

11.      E.g.,  the Commission should apply a more flexible interpretation of
         the integration requirements under the Act; interconnection through
         power pools, reliability councils and  wheeling arrangements can
         satisfy  the physical interconnection requirement of  section
         2(a)(29); the geographic requirements  of section  2(a)(29) should be
         interpreted flexibly, recognizing  technical advances  consistent with
         the purposes and provisions of the Act; the Commission's  analysis
         should focus on whether the resulting system will be subject to
         effective regulation;  the Commission  should liberalize its
         interpretation of  the "A-B-C" clauses  and permit  combination
         systems  where the affected states agree, and the Commission should
         "watchfully defer" to the work of other regulators.  1995 Report at
         71-7.

12.      E.g., the Commission  should  promulgate rules to reduce the regulatory
         burdens  associated  with   energy-related   diversification   and  the
         Commission  should adopt a more flexible  approach in  considering  all
         other requests to enter into diversified activities.
         1995 Report at 88-90.

13.      The applicants acknowledge the requirements of Section 17(c) of the Act
         and Rule 70 thereunder  with respect to limitations  upon directors and
         officers of  registered  holding  companies  and  subsidiary  companies
         thereof having  affiliations with commercial  banking  institutions and
         investment  bankers,   and  undertake  that,  upon  completion  of  the
         Transaction,  they will be in compliance with the applicable provisions
         thereof.

14.      1995 Report at 73-4.

15.      The shares of Utilities Preferred Stock and IPC Preferred Stock
         outstanding at the time of the consummation of the Transaction will
         remain outstanding preferred stock of Utilities and IPC respectively;
         provided that, if Reincorporation Mergers are effected, the Utilites
         Prepared Stock will be redeemed, and each share of IPC Preferred Stock
         (other than IPC Dissenting Shares) will be converted into one share of
         New IPC Preferred Stock with terms and designations substantially
         identical to those of the IPC Preferred Stock.

16.      This number is a preliminary estimate only, and will be updated as
         necessary.

17.      By their  terms,  Sections  8 and 11 only apply to  registered  holding
         companies and are therefore  inapplicable at present to WPLH,  since it
         is not now a registered  holding company.  The following  discussion of
         Sections  8  and  11  is  included  only  because,  under  the  present
         transaction  structure,  Interstate  Energy will  register as a holding
         company after consummation of the Transaction.

         176 (1966). It should be noted that the Commission continued to give
         primacy to state utility commission determinations in making decisions
         regarding combination exempt holding companies.  See, e.g., In re
         Northern States Power Co., Holding Co. Act Release No. 12655 (Sept. 16,
         1954); Delmarva Power & Light Co., 46 S.E.C 710 (1976); WPL Holdings,

         183-184 (1966).  It is important to note that this issue - basically an
         anti-trust issue - was the principal concern in previous decisions
         ordering the separation of gas and electric systems and clearly is no
         longer applicable to the changed utility competitive environment.

25.      On December 12, 1995, the PSCW announced a determination outlining the
         general direction of electric utility regulation in Wisconsin.  It
         includes a restructuring of the industry providing choice of
         electricity provider for all consumers by the year 2000 as well as
         establishment of a competitive generation business.  The transmission
         and distribution functions would remain regulated. In a February 22,
         1996 report to the Wisconsin legislature, the PSCW identified a 32 step
         plan that it would follow for electric utility restructuring in
         Wisconsin.  In the plan, the PSCW indicated that during 1996 it will
         begin activities on 12 of these steps, some of which would seek changes
         in applicable administrative rules under its jurisdiction, including
         affiliated interest standards and quality of service standards.  The
         PSCW expects to present an electric utility restructuring plan to the
         Wisconsin Legislature in 1997.

         The PSCW also  continued  a generic  investigation  of the  natural gas
         industry in Wisconsin  and  addressed  the extent to which  traditional
         regulations   should  be  replaced  with  a  different   approach.   In
         conjunction  with  this  generic  investigation,   the  PSCW  staff  is
         reviewing  the use of the  current  purchased  gas  adjustment  ("PGA")
         mechanism  which is designed to pass on to gas  customers  increases or
         decreases in the cost of natural gas purchased  for resale.  A separate
         docket has been established to review the PGA.

         1, 1997) (New Century Energies Inc., a registered holding company, is
