                                  PART I

This Annual Report on Form 10-K includes information relating to Alliant
Energy, IESU and WP&L (as well as IPC, Resources and Corporate
Services).  Where appropriate, information relating to a specific entity
has been segregated and labeled as such.

ITEM 1.  BUSINESS

A. GENERAL
- ----------
Alliant Energy was formed as the result of a three-way merger involving
WPLH, IES and IPC that was completed in April 1998.  The primary first
tier subsidiaries of Alliant Energy include: WP&L, IESU, IPC, Resources
and Corporate Services.  Among various other regulatory constraints,
Alliant Energy is operating as a registered public utility holding
company subject to the limitations imposed by PUHCA.  Alliant Energy was
incorporated in Wisconsin in 1981.  A brief description of the primary
first-tier subsidiaries of Alliant Energy is as follows:

1)  IESU - incorporated in Iowa in 1925 as Iowa Railway and Light
Corporation.  IESU is a public utility engaged principally in the
generation, transmission, distribution and sale of electric energy; the
purchase, distribution, transportation and sale of natural gas; and the
provision of steam services in selective markets, in the State of Iowa.
In Iowa, non-exclusive franchises, which cover the use of streets and
alleys for public utility facilities in incorporated communities, are
granted for a maximum of twenty-five years by a majority vote of local
qualified residents.  At December 31, 1999, IESU supplied electric and
gas service to approximately 345,000 and 181,000 customers,
respectively.  In 1999, 1998 and 1997, IESU had no single customer for
which electric and/or gas sales accounted for 10% or more of IESU's
consolidated revenues.

2)  WP&L - incorporated in Wisconsin in 1917 as the Eastern Wisconsin
Electric Company, is a public utility engaged principally in the
generation, transmission, distribution and sale of electric energy; the
purchase, distribution, transportation and sale of natural gas; and the
provision of water services in selective markets.  Nearly all of WP&L's
customers are located in south and central Wisconsin.  WP&L operates in
municipalities pursuant to permits of indefinite duration which are
regulated by Wisconsin law.  At December 31, 1999, WP&L supplied electric
and gas service to approximately 407,000 and 162,000 customers,
respectively.  WP&L also has approximately 19,000 water customers.  In
1999, 1998 and 1997, WP&L had no single customer for which electric
and/or gas sales accounted for 10% or more of WP&L's consolidated
revenues.  WP&L owns all of the outstanding capital stock of South
Beloit, a public utility supplying electric, gas and water service,
principally in Winnebago County, Illinois, which was incorporated in
1908.  WP&L also owns varying interests in several other subsidiaries and
investments which are not material to WP&L's operations.

3)  IPC - incorporated in 1925 under the laws of the State of Delaware.
IPC is a public utility engaged principally in the generation,
transmission, distribution and sale of electric energy and the purchase,
distribution, transportation and sale of natural gas in the States of
Iowa, Minnesota and Illinois.  At December 31, 1999, IPC provided
electric and gas service to approximately 167,000 and 50,000 customers,
respectively.  In 1999, 1998 and 1997, IPC had no single customer for
which electric and/or gas sales accounted for 10% or more of IPC's
consolidated revenues.

4)  RESOURCES - incorporated in 1988 in Wisconsin and the majority of
Alliant Energy's non-regulated investments are organized under
Resources.  Resources' wholly-owned subsidiaries include ISCO,
International, Investments, Transportation and Capital Square.  These
businesses include domestic and international energy products and
services businesses; industrial services, which includes environmental,
engineering and transportation services; investments in affordable
housing initiatives; and investments in various other strategic
initiatives.  Alliant Energy also has a 50% ownership interest in a joint
venture, which is managed by Resources, with Cargill, named
Cargill-Alliant LLC.

5)  CORPORATE SERVICES - subsidiary formed to provide administrative
services to Alliant Energy and its subsidiaries as required under PUHCA.

ELECTRIC UTILITY OPERATIONS
General
As of December 31, 1999, Alliant Energy's utility subsidiaries provided
electricity to approximately 919,000 retail customers in approximately
1,358 communities in Iowa, southern and central Wisconsin, northern and
northwestern Illinois and southern Minnesota.  The approximate number of
electric retail customers, communities and wholesale customers served for
each of the individual utilities at December 31, 1999 was as follows:

          Retail      Communities     Wholesale
         Customers      Served        Customers
         ----------  ------------  --------------
IESU      345,000        525              5
WP&L      407,000        599             28
IPC       167,000        234             10

Electric utility operations accounted for 78.4%, 83.3% and 86.0% of
operating revenues and 92.6%, 89.9% and 91.6% of operating income for
IESU, WP&L and IPC, respectively, for the year ended December 31, 1999.

Electric sales are seasonal to some extent with the annual peak normally
occurring in the summer months.  In 1999, the maximum peak hour demand
for IESU was 1,990 MW and occurred on July 27, 1999.  For WP&L and IPC,
the maximum peak hour demands were 2,397 MW on July 23, 1999 and 1,015 MW
on July 29, 1999, respectively.

IESU maintains and operates transmission and substation facilities
connecting with its high voltage transmission systems pursuant to a
non-cancelable operation agreement (the Operating Agreement) with CIPCO.
The Operating Agreement, which will terminate on December 31, 2035,
provides for the joint use of certain transmission facilities of IESU and
CIPCO.  Alliant Energy has transmission interconnections at various
locations with twelve other transmission owning utilities in the
Midwest.  These interconnections enhance the overall reliability of the
Alliant Energy transmission system and provide access to multiple sources
of economic and emergency power and energy.

IESU and IPC are currently full members of MAPP.  WP&L is a member of the
MAPP Regional Transmission Group.  MAPP is one of the ten regional
members of the NERC.  Each regional member of NERC is responsible for
maintaining reliability in its area through coordination of planning and
operations.  WP&L is also a full member of MAIN, another regional member
of NERC.  IESU and IPC are currently exploring the possibility of
transitioning from the MAPP reliability region to MAIN so all of Alliant
Energy will belong to the same reliability region.  Alliant Energy is
unable to predict the outcome of this issue at this time.

Refer to the "Utility Industry Outlook" section in Item 7. MD&A for
additional information regarding the future of Alliant Energy's
transmission business.  Refer to Item 2. "Properties" for additional
information regarding electric facilities.

Refer to the Electric Operating Information tables for details on the
sources of electric energy for Alliant Energy, IESU and WP&L during 1995
to 1999.

Coal
Corporate Services, as an agent of IESU, WP&L and IPC, has negotiated
several agreements with different suppliers to ensure that a specified
supply of coal is available at known prices for the respective utilities
for calendar years 2000, 2001, and 2002.  These contracts, in combination
with existing agreements, provide for a portfolio of coal supplies that
cover approximately 100%, 60% and 10% of the three utilities' estimated
coal supply needs for the years 2000 through 2002, respectively.
Management believes this portfolio of coal supplies represents a
reasonable balance between ensuring an adequate supply and ensuring that
the prices paid for coal is at the then current market conditions.
Remaining coal requirements will be met from either future contracts or
purchases in the spot market.

The majority of the coal utilized by Alliant Energy is from the Wyoming
Powder River Basin.  A majority of this coal is transported by rail-car
directly from Wyoming to Alliant Energy's generating facilities, with the
remainder transported from Wyoming to the Mississippi River by rail-car
and then via barges to the final destination.  As protection against
interruptions in coal deliveries, Alliant Energy maintains average coal
inventories at its generating stations of 40 to 50 days for stations with
year-round deliveries and 30 to 150 days (depending upon time of the
year) for stations with seasonal deliveries.

Alliant Energy anticipates that its average fossil fuel costs will likely
increase in the future due to price/rate adjustment provisions in
existing coal and transportation contracts.  Price adjustment provisions
in existing coal contracts are primarily based on changes in various
indices (e.g. U.S. Department of Labor Statistics Producer Price Indices
and Consumer Price Indices).  Other factors which impact coal price
adjustment provisions are mine labor agreements and, if enacted, changes
in various laws and regulations.  Rate adjustment provisions in
transportation contracts are primarily based on changes in the Rail Cost
Adjustment Factor as published by the U.S. Surface Transportation Board.
In addition, fuel sulfur restrictions and other environmental limitations
have increased significantly and will likely further increase the
difficulty and cost of obtaining adequate coal supplies.  See Note 1(j)
of the "Notes to Consolidated Financial Statements" for a discussion of
the utilities' rate recovery of fuel costs.

Refer to Note 12(b) of the "Notes to Consolidated Financial Statements"
for details relating to Alliant Energy's coal purchase commitments.

                                       10
<PAGE>

Purchased Power
During the year ended December 31, 1999, approximately 25.0%, 25.0% and
32.3% of IESU's, WP&L's and IPC's total MWH requirements, respectively,
were met through purchased power.  Refer to Note 12(b) of the "Notes to
Consolidated Financial Statements" for details relating to purchase power
commitments.

Nuclear
General - Alliant Energy owns interests in two nuclear facilities,
- -------
Kewaunee and DAEC.  Kewaunee, a 532 MW (net capacity) pressurized water
reactor plant, is operated by WPSC and is jointly owned by WPSC (41.2%),
WP&L (41.0%) and MG&E (17.8%).  The Kewaunee operating license expires in
2013.  DAEC, a 535 MW (net capacity) boiling water reactor plant, is
operated by IESU which has a 70% ownership interest in the plant.  The
DAEC operating license expires in 2014.  See Item 7. MD&A "Liquidity and
Capital Resources - Capital Requirements - Nuclear Facilities" for a
discussion of an agreement between WPSC and MG&E regarding future
ownership of Kewaunee as well as Alliant Energy's participation in the
NMC.

As co-owners of nuclear generating units, IESU and WP&L are subject to
the jurisdiction of the NRC.  The NRC has broad supervisory and
regulatory jurisdiction over the construction and operation of nuclear
reactors, particularly with regard to public health, safety and
environmental considerations.  The operation and design of nuclear power
plants is under constant review by the NRC.  IESU and WP&L have complied
with and are currently complying with all NRC requests for data relating
to these reviews.  As a result of such reviews, further changes in
operations or modifications of equipment may be required, the cost of
which cannot currently be estimated.  IESU's and WP&L's anticipated
nuclear-related construction expenditures for 2000-2004 are approximately
$59 million and $35 million, respectively.  Refer to "Liquidity and
Capital Resources - Capital Requirements" in Item 7. MD&A for a further
discussion.

Under the Price-Anderson Amendments Act of 1988 (1988 Act), IESU and WP&L
currently have the benefit of public liability coverage which would
compensate the public in the event of an accident at a commercial nuclear
power plant.  The 1988 Act permits such coverage to rise with increased
availability of nuclear insurance and the changing number of operating
nuclear plants subject to retroactive premium assessments.  The 1988 Act
provides for inflation indexing (Consumer Price Index every fifth year)
of the retroactive premium assessments.

As an outgrowth of the Three Mile Island Nuclear Power Plant experience,
nuclear plant owners have initiated a cooperative insurance program
designed to help cover business interruption expenses for participating
utilities arising from a possible nuclear plant event.  IESU and WP&L are
participants in this program.  This type of insurance is an industry
response intended to lessen the cost burden on customers in the event of
a lengthy plant shutdown.

In the unlikely event of a catastrophic loss at Kewaunee or DAEC, the
amount of insurance available may not be adequate to cover property
damage, decontamination and premature decommissioning.  Uninsured losses,
to the extent not recovered through rates, would be borne by WP&L or IESU
and could have a material adverse effect on their financial condition and
results of operations.  Refer to Note 12(e) of the "Notes to Consolidated
Financial Statements" for a further discussion of the nuclear insurance
issue.

Kewaunee - WPSC purchases uranium concentrates, conversion services,
- --------
enrichment services, and fabrication services for nuclear fuel assemblies
at Kewaunee.  New fuel assemblies replace used assemblies that are
removed from the reactor every 18 months and placed in storage at the
plant site pending removal by the DOE.  Uranium concentrates, conversion
services, and enrichment services are purchased at spot market prices,
through a bid process, or using existing contracts.  Conversion services
are complete for nuclear fuel reloads in 2000, 2001 and 2003.  A fixed
quantity of enrichment services are contracted through the year 2004.
Additional enrichment services will be acquired under a contract which is
in effect for the life of the plant or by purchases on the spot market.
Fuel fabrication services are contracted well into the next decade and
contain contractual clauses covering force majeure and termination
provisions.  A uranium inventory policy requires that sufficient
inventory exist for up to two reactor reloads of fuel.  As of December
31, 1999, 983,000 pounds of yellowcake or its equivalent were held in
inventory for the plant.

DAEC - A contract for enrichment services and enriched uranium product
- ----
was signed with the USEC in 1995.  This contract is effective through


                                       11
<PAGE>

September of 2001.  Fabrication of the nuclear fuel is being performed by
General Electric Company for fuel through the 2011 refueling of DAEC.
IESU believes that an ample supply of uranium and enrichment services
will be available in the future and intends to purchase such uranium and
enrichment services as necessary on the spot market and/or via medium
length (less than five years) contracts to supplement its current
contracts and meet its generation requirements.

Additional discussions of various other nuclear issues relating to
Kewaunee and DAEC are included in Item 7. MD&A and the "Notes to
Consolidated Financial Statements."

Power Supply
Refer to "Other Matters - Power Supply" in Item 7. MD&A for a discussion
of power supply concerns.

Electric Environmental Matters
Alliant Energy is regulated in environmental matters by a number of
federal, state and local agencies.  Such regulations are the result of a
number of environmental laws passed by the U.S. Congress, state
legislatures and local governments and enforced by federal, state and
local agencies.  The laws impacting Alliant Energy's operations include,
but are not limited to, the Clean Water Act; Safe Drinking Water Act;
Clean Air Act, as amended by the Clean Air Act Amendments of 1990;
National Environmental Policy Act; Toxic Substances Control Act;
Emergency Planning and Community Right-to-Know Act; Resource Conservation
and Recovery Act; Comprehensive Environmental Response, Compensation and
Liability Act of 1980 (CERCLA), as amended by the Superfund Amendments
and Reauthorization Act of 1986; Nuclear Waste Policy Act of 1982;
Occupational Safety and Health Act; and the National Energy Policy Act of
1992.  Alliant Energy regularly obtains federal, state and local permits
to assure compliance with the environmental protection laws and
regulations.  Costs associated with such compliance have increased in
recent years and are expected to increase moderately in the future.

Refer to "Other Matters - Environmental" in Item 7. MD&A and Note 12 of
the "Notes to Consolidated Financial Statements" for a further discussion
of electric environmental matters.

GAS UTILITY OPERATIONS
As of December 31, 1999, Alliant Energy's utility subsidiaries provided
retail natural gas service to approximately 393,000 customers in
approximately 488 communities in Iowa, southern and central Wisconsin,
northern and northwestern Illinois and southern Minnesota.  The
approximate number of customers and communities served for each of the
individual utilities at December 31, 1999 was as follows:


            Gas Customers     Communities Served
           ----------------  ----------------------
IESU            181,000              212
WP&L            162,000              235
IPC              50,000               41


Gas utility operations accounted for 18.2%, 16.0% and 14.0% of operating
revenues and 5.2%, 8.9% and 8.4% of operating income for IESU, WP&L and
IPC, respectively, for the year ended December 31, 1999.  These
operations include providing gas services to transportation and retail
customers.

In providing gas commodity service to retail customers, Alliant Energy
administers a diversified portfolio of transportation and storage
contracts on behalf of each of the three utilities.  Transportation
contracts with NNG, NGPL and ANR allow access to gas supplies located in
the U.S. and Canada.  Non-traditional arrangements provide IESU and WP&L
with gas delivered directly to their service territories.  The maximum
daily delivery capacity of the individual utilities for the year ended
December 31, 1999 was as follows:

</TABLE>

IESU, WP&L and IPC maintain purchase agreements with over 50 suppliers of
natural gas from all gas producing regions of the U.S. and Canada.
Approximately half of the gas supply contracts are for terms of six
months or less, with the remaining supply contracts having
terms up to two years.  The utilities' gas supply commitments are
index-based.

In addition to sales of natural gas to retail customers, IESU, WP&L and
IPC provide transportation service to commercial and industrial customers
by moving customer-owned gas through Alliant Energy's distribution system
to the customers' meter.  Revenues are collected for this service
pursuant to transportation tariffs.

The gas sales of the utility subsidiaries follow a seasonal pattern.
There is an annual base load of gas used for cooking, heating and other
purposes, with a large heating peak occurring during the winter season.
Producers, marketers and brokers, as well as storage contracts, supply
natural gas to meet the peak heating season requirements.  Storage
contracts allow the utilities to purchase gas in the summer, store the
gas in underground storage fields and deliver it in the winter.  Gas
storage met approximately 19%, 26% and 25% of IESU's, WP&L's and IPC's
annual gas requirements in 1999, respectively.

for a discussion of Alliant Energy's rate recovery mechanisms for its
natural gas costs and Note 12(b) of the "Notes to Consolidated Financial
Statements" for a discussion of Alliant Energy's gas commitments.

ITEM 3.  LEGAL PROCEEDINGS

Alliant Energy
On July 15, 1999, the PSCW found that Alliant Energy was in violation of
the PSCW's merger order because after Alliant Energy exercised its right
to withdraw from the Midwest ISO, it had no proposal on file with the
PSCW either to be in an ISO or to spin off its transmission assets
(Alliant Energy has subsequently rejoined the Midwest ISO).  The PSCW
deferred consideration of any remedies.  Both Alliant Energy and the
intervenors in the proceeding had appealed the PSCW's decision to the
Dane County Circuit Court however the intervenors have since withdrawn
their appeal.  Alliant Energy's appeal is still pending.

Alliant Energy received an adverse ruling in 1999 from a U.S. district
court judge dealing with an income tax refund claim Alliant Energy filed
relating to capital losses disallowed under audit by the IRS.  The
district court judge also disallowed certain related deductions allowed
by the IRS as an offset against a tax refund due to Alliant Energy.
Alliant Energy has appealed the district court's ruling and such appeal
is pending.  The IRS has appealed the decision which led to the tax
refund due to Alliant Energy and this appeal is also pending.  Alliant
Energy believes the resolution of these issues will not have a material
adverse impact on its financial condition or results of operations.

WP&L
In the second quarter of 1999, WP&L received a demand for arbitration
from MG&E pursuant to the terms of joint plant operating agreements
between the parties regarding issues of ownership and operation of the
Columbia Energy Center.  In September 1999, a Wisconsin Circuit Court
judge ruled that some of MG&E's claims were arbitrable.  The parties have
selected the arbitrators and the procedural schedule is being developed.
WP&L believes MG&E's claims are without merit and will be vigorously
defending its position.

Environmental Matters
The information required by Item 3 with regards to environmental matters
is included in Notes 12(f) and 12(g) of Item 8. "Notes to Consolidated

Stock closing price at December 31, 1999:  $27 1/2

Although Alliant Energy's practice has been to pay common stock dividends
quarterly, the timing of payment and amount of future dividends are
necessarily dependent upon earnings, financial requirements and other
factors.

At December 31, 1999, there were approximately 66,886 holders of record of
Alliant Energy's stock including underlying holders in Alliant Energy's
Shareowner Direct Plan.

Alliant Energy is the sole common shareowner of all 13,370,788 shares of
IESU Common Stock currently outstanding.  During 1999, 1998 and 1997, IESU
declared dividends on its common stock of $88 million, $19 million and $56
million, respectively, to its parent.  No dividend payments were made in
the last three quarters of 1998 due to merger-related tax considerations.
As a result, the dividend payment in the first quarter of 1999 was larger
than IESU's historical quarterly payment.  IESU has the right under the
terms of its Subordinated Deferrable Interest Debentures, so long as an
Event of Default (as defined therein) has not occurred and is not
continuing, to extend the interest payment period at any time and from time
to time on the Subordinated Deferrable Interest Debentures to a period not
exceeding 20 consecutive quarters.  If IESU exercises its right to extend
the interest payment period, IESU may not, during any such extended
interest payment period, declare or pay dividends on, or redeem, purchase
or acquire, or make any liquidation payment with respect to, any of its
capital stock or make any guarantee payment with respect to the foregoing.
IESU does not intend to exercise its right to extend the interest payment
period.

Alliant Energy is the sole common shareowner of all 13,236,601 shares of
WP&L common stock currently outstanding.  During 1999, 1998 and 1997, WP&L
paid dividends on its common stock of $58 million each year to its parent.
WP&L's common stock dividends are restricted to the extent that such
dividends would reduce the common stock equity ratio to less than 25%.
Under rate order UR-110, the PSCW ordered that it must approve the payment
of dividends by WP&L to Alliant Energy that are in excess of the level
forecasted in the rate order ($58.3 million), if such dividends would
reduce WP&L's average common equity ratio below 52.00% of total
capitalization.  The dividends paid by WP&L to Alliant Energy since the
rate order was issued have not exceeded the level forecasted in the rate
order.

Alliant Energy's utility subsidiaries each have common stock dividend
restrictions based on their respective bond indentures and articles of
incorporation.  Each utility has restrictions on the payment of common
stock dividends that are commonly found with preferred stock.  In addition,
IESU's and IPC's ability to pay common stock dividends is restricted based
on requirements associated with sinking funds.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
                OF OPERATIONS

Alliant Energy was formed as the result of a three-way merger involving WPLH,
IES and IPC that was completed in April 1998.  The primary first tier
subsidiaries of Alliant Energy include: WP&L, IESU, IPC, Resources and
Corporate Services.  Among various other regulatory constraints, Alliant
Energy is operating as a registered public utility holding company subject to
the limitations imposed by PUHCA.  This MD&A includes information relating to
Alliant Energy, IESU and WP&L (as well as IPC, Resources and Corporate
Services).  Where appropriate, information relating to a specific entity has
been segregated and labeled as such.

                           FORWARD-LOOKING STATEMENTS

Statements contained in this report (including MD&A) that are not of
historical fact are forward-looking statements intended to qualify for the
safe harbors from liability established by the Private Securities Litigation
Reform Act of 1995.  From time to time, Alliant Energy, IESU or WP&L may make
other forward-looking statements within the meaning of the federal securities
laws that involve judgments, assumptions and other uncertainties beyond the
control of such companies.  These forward-looking statements may include,
among others, statements concerning revenue and cost trends, cost recovery,
cost reduction strategies and anticipated outcomes, pricing strategies,
changes in the utility industry, planned capital expenditures, financing needs
and availability, statements of expectations, beliefs, future plans and
strategies, anticipated events or trends and similar comments concerning
matters that are not historical facts.  Investors and other users of the
forward-looking statements are cautioned that such statements are not a
guarantee of future performance and that such forward-looking statements are
subject to risks and uncertainties that could cause actual results to differ
materially from those expressed in, or implied by, such statements.  Some, but
not all, of the risks and uncertainties include weather effects on sales and
revenues, competitive factors, general economic conditions in the relevant
service territory, federal and state regulatory or government actions,
including issues associated with the deregulation of the utility industry,
unanticipated construction and acquisition expenditures, issues related to
stranded costs and the recovery thereof, the operations of Alliant Energy's
nuclear facilities, unanticipated costs associated with certain environmental
remediation efforts being undertaken by Alliant Energy, unanticipated issues
relating to establishing a transmission company, material changes in the value
of Alliant Energy's investment in McLeod, technological developments, employee
workforce factors, including changes in key executives, collective bargaining
agreements or work stoppages, political, legal and economic conditions in
foreign countries Alliant Energy has investments in and changes in the rate of
inflation.

                            UTILITY INDUSTRY OUTLOOK

As a holding company with significant utility assets, Alliant Energy competes
in an ever-changing utility industry.  Set forth below is an overview of this
evolving marketplace.

Electric energy generation, transmission and distribution are in a period of
fundamental change in the manner in which customers obtain, and energy
suppliers provide, energy services.  As legislative, regulatory, economic and
technological changes occur, electric utilities are facing increased numbers
of alternative suppliers.  Such competitive pressures could result in loss of
customers and an incurrence of stranded costs (i.e., assets and other costs
rendered unrecoverable as the result of competitive pricing).  To the extent
stranded costs cannot be recovered from customers, they would be borne by
security holders.

Across the nation, approximately half of the states (including Illinois) have
passed legislation or issued regulatory rulings granting customers the right
to choose their electric energy supplier.  Legislation that would allow
customers to choose their electric energy supplier is expected to be
introduced in Iowa in 2000.  At the federal level, a number of proposals to
restructure the electric industry are currently under consideration.  However,
there continues to be a lack of consensus over how restructuring should be
implemented and how much control the federal government should have over this
process.  Until one of the proposals gains significant bipartisan support,
there is unlikely to be final federal action to either facilitate or force
states to open electricity markets to competition.


                                       27
<PAGE>


Alliant Energy realized 55%, 40%, 3% and 2% of its electric utility revenues
in 1999 in Iowa, Wisconsin, Minnesota and Illinois, respectively.
Approximately 90% of the electric revenues were regulated by the respective
state commissions while the other 10% were regulated by the FERC.  Alliant
Energy realized 57%, 37%, 3% and 3% of its gas utility revenues in Iowa,
Wisconsin, Minnesota and Illinois, respectively, during the same period.

IESU realized 100% of its electric and gas utility retail revenues in 1999 in
Iowa.  Approximately 95% of the electric revenues in 1999 were regulated by
the IUB while the other 5% were regulated by the FERC.  WP&L realized 98% of
its electric utility revenues in 1999 in Wisconsin and 2% in Illinois.
Approximately 84% of the electric revenues in 1999 were regulated by the PSCW
or the ICC while the other 16% were regulated by the FERC.  WP&L realized 96%
of its gas utility revenues in 1999 in Wisconsin and 4% in Illinois.

Federal Regulation
IESU, WP&L and IPC are subject to regulation by the FERC.  NEPA addresses
several matters designed to promote competition in the electric wholesale
power generation market.  FERC has issued final rules (FERC Orders 888/888-A
and 889/889-A) requiring electric utilities to open their transmission lines
to other wholesale buyers and sellers of electricity.  In response to FERC
Orders 888 and 888-A, Corporate Services, on behalf of IESU, WP&L and IPC, has
filed Open Access Transmission Tariffs that comply with the orders.  In
response to FERC Orders 889 and 889-A, IESU, WP&L and IPC are participating in
a regional Open Access Same-Time Information System.

FERC Order 888 permits utilities to seek recovery of legitimate, prudent and
verifiable stranded costs associated with providing open access transmission
services.  FERC does not have jurisdiction over retail distribution and,
consequently, the final FERC rules do not provide for the recovery of stranded
costs resulting from retail competition.  The various states retain
jurisdiction over the question of whether to permit retail competition, the
terms of such retail competition, and the recovery of any portion of stranded
costs that are ultimately determined to have resulted from retail competition.

In May 1999, FERC issued a NOPR concerning the development of RTOs.  The
proposed rules outline the requirements for utilities to voluntarily turn over
control of their transmission system to a regional entity either by leasing
the system to an RTO or by outright divestiture.  In December 1999, FERC
issued Order 2000 which implemented the proposed rules with minor
modifications.  FERC's timeline is to have the RTOs in operation by the end of
2001.  Alliant Energy is involved with other utilities and industry groups in
reviewing Order 2000 and has submitted a joint petition to FERC seeking
further clarification of the operating and ownership limitations that will be
imposed on the RTOs.  Alliant Energy's current plans to contribute its
Wisconsin transmission assets to ATC, in exchange for an equity interest, and
participate in the Midwest ISO are expected to comply with the provisions of
Order 2000.

Alliant Energy and the utility subsidiaries cannot predict the long-term
consequences of these rules on their financial condition or results of
operations.

State Regulation
Iowa - IESU and IPC are subject to regulation by the IUB.  The IUB has been
- ----
reviewing all forms of competition in the electric utility industry for
several years.  A group comprised of the IUB, Alliant Energy, MidAmerican
Energy Company, rural electric cooperatives, municipal utilities and Iowans
for Choice in Electricity (a diverse group of industrial customers, marketers,
such as Enron, and a low income customer representative, among others)
endorsed a bill to allow for such competition that was introduced in the Iowa
Legislature in March 1999.  The bill was opposed by the OCA, which is charged
by Iowa law with representation of all consumers generally.  While the bill
did not pass, by operation of House rules, it was re-referred to the House
Commerce Committee and was again inserted into the legislative process in the
Second Regular Session of the 78th General Assembly (2000).  As of March 1,
2000, the bill has been approved by both the Iowa House and Senate Commerce
Committees and will be addressed by the legislature in full.

The bill would allow choice of electric suppliers for all customers on October
1, 2002.  It would freeze IESU's and IPC's Iowa regulated prices at January
2000 levels.  It would allow, however, for investor-owned utilities to propose

                                       28
<PAGE>

increases due to exogenous factors (for example, environmental compliance
costs) in the generation cost component.  Assigned service territories would
be maintained for the delivery function.  Delivery prices would be regulated,
with the option available to propose performance based rate making.  Prices
for generation and other retail services would not be regulated, except for
SOS pricing starting October 2002 for all residential customers and
non-residential customers with annual usage of fewer than 75,000 KWHs.
Pricing for SOS would initially be at levels equivalent to prices as they
exist today and would remain at such levels until at least December 31, 2005
for SOS customers.  The IUB would be able to terminate SOS if it were to
determine several conditions existed, including, most importantly, that
effective competition existed such that regulation was no longer necessary.
If the IUB continues SOS past December 31, 2005, then prices would be based
upon competitive bids.  There are no price protections for non-residential
customers with usage greater than 75,000 KWH annually, with the exception of
transitional service.  Transitional service would exist for no longer than one
year, until October 1, 2003, at prices the IUB determines to be "just and
reasonable."  Currently existing automatic fuel adjustment clauses for
recovery of fuel costs would be eliminated no later than October 2002.  A
"nuclear-only" fuel adjustment would be permitted with increased prices
effective if an electric company's nuclear plant is not operational due to
exogenous factors.

Transition or stranded cost is the difference between the revenues that would
have been collected pursuant to an electric company's revenue requirement
existing as of January 1, 2000, and market prices for the period 2002 through
2005.  These differences would be afforded 80% recovery in the first twelve
months of choice, with 70%, 60%, and 50% in each subsequent twelve-month
period.  Effective October 1, 2006, transition cost recovery would end.  In
lieu of accepting this transition cost recovery mechanism, an electric utility
would be entitled under the proposed legislation to elect to divest itself of
its generation assets, including power supply contracts.  In such case, the
utility would be given an opportunity to be "made whole" for recovery of
embedded costs with the possibility for shareowners to retain 50% of the
amount realized from the sale of the assets beyond the sum of depreciated book
value and unfunded decommissioning.  A divestiture plan would be filed with
the IUB no later than January 1, 2001, with IUB approval or modification by
July 1, 2001.  The utility would have until September 30, 2001 to revoke its
election.

Costs of start-up, including computer systems and employee transition costs,
would be recoverable over a ten-year period, as approved by the IUB.  The
difference between regulatory assets and liabilities would be fully
recoverable as a delivery charge.  Nuclear decommissioning costs would be
fully recoverable.  While Alliant Energy supports the proposed legislation in
its current form, it is unable to predict if this legislation will be enacted
in 2000, what modifications, if any, may be made to the proposed bill or what
actions Alliant Energy may take in response to the legislation should it be
enacted.

In the first quarter of 1999, the IUB conducted workshops concerning the
unbundling of natural gas rates for all Iowa customers as well as allowing
choice of the supplier of the natural gas for the small volume natural gas
customers.  IESU's and IPC's natural gas costs are a "flow-through cost item"
in that they are automatically reflected in future billings to customers.
Such collections are reconciled on an annual basis to ensure that they neither
over- nor under-collect their actual gas commodity costs.  Consequently,
Alliant Energy does not currently realize any margins or income with respect
to its provision of the gas commodity.  Alliant Energy expects to continue to
be made whole for such gas costs if the gas rates are unbundled.  Even if
Alliant Energy's gas commodity sales were to decline in a customer choice
environment, its margins and income would not be expected to be impacted by
such decreases in commodity sales.  The delivery function of Alliant Energy's
gas business in Iowa will likely continue to be regulated on a cost of service
basis, as currently is the case.  As a result, assuming no significant change
in the regulatory posture, the delivery function would continue to generate
comparable margins and income to that currently generated, regardless of what
entity provides the gas commodity to the customer.  On March 3, 2000, the IUB
issued an order indicating that the IUB prefers to allow each utility to
design a tariff in order to remove barriers to a competitive option for small
volume customers.  The IUB will also seek comments from the utility companies
before approving any tariff filings.

Wisconsin - WP&L is subject to regulation by the PSCW.  The PSCW's inquiries
- ---------
into the future structure of the natural gas and electric utility industries
are ongoing.  The stated goal of the PSCW regarding natural gas service is "to
accommodate competition but not create it."  The PSCW has followed a measured
approach to restructuring the natural gas industry in Wisconsin.  The PSCW has
determined that customer classes will be deregulated (i.e., the gas utility
would no longer have an obligation to procure gas commodity for customers, but

                                       29
<PAGE>

would still have a delivery obligation) in a step-wise manner, after each
class has been demonstrated to have a sufficient number of gas suppliers
available.  The short-term goals of the PSCW's electric restructuring process
are to ensure reliability of the state's electric system and development of a
robust wholesale electric market.  The long-term goal is to establish
prerequisite safeguards to protect customers prior to allowing retail customer
choice.  There are no other restructuring working groups currently active in
Wisconsin.

In May 1998, the PSCW reactivated Docket No. 05-BU-101 with the objective of
examining the degree of separation which should be required as a matter of
policy between utility and non-utility activities involving the various state
utilities.  Final hearings were held in February 2000 and the PSCW ruled that
utilities can continue to offer non-utility services to customers and
affiliates and that utilities must continue to fully allocate their costs to
such non-utility activities.

It is anticipated that there will be legislative proposals introduced in the
2001-2002 legislative session on issues dealing with restructuring of the
electric utility industry.  It is not possible to predict at this time the
scope or the possibility of enactment of such proposals.

"Reliability 2000" legislation was enacted in Wisconsin in 1999.  This
legislation included, among other items, a relaxation of the non-utility asset
limitations included in the WUHCA and the formation of a Wisconsin
transmission company for those Wisconsin utility holding companies who elect
to take advantage of the new asset cap law.  Alliant Energy has agreed to
contribute WP&L's transmission assets to the transmission company (American
Transmission Company, or ATC) in exchange for an equity interest in ATC.  WP&L
made several federal and state regulatory filings and commitments in the
fourth quarter of 1999 relating to its participation in ATC.

ATC's sole business will be to provide reliable, economic transmission service
to all customers in a fair and equitable manner.  ATC will plan, construct,
operate, maintain and expand transmission facilities it will own to provide
for adequate and reliable transmission of power.  It will provide comparable
service to all customers, including Alliant Energy, and it will support
effective competition in energy markets without favoring any market
participant.  Formation of the company will require federal and state
regulatory approvals.  ATC will be regulated by FERC for all rate terms and
conditions of service.  ATC will be a transmission-owning member of the
Midwest ISO and will transfer operational control of the transmission systems
to the Midwest ISO.

ATC will be a public utility, as defined under Wisconsin law, with a board of
directors comprised of one representative from each utility having at least a
10% ownership interest in ATC.  Smaller utilities could combine their
transmission assets with others to reach the minimum level for board
membership.  In addition, the shareowners of ATC will select four at-large
directors that can not be employed or engaged in energy businesses.

The PSCW has not yet determined the exact scope of the assets that must be
transferred to the ATC.  Pending the final determination by the PSCW, WP&L
estimates it will transfer approximately $150 million in plant assets at net
book value to the ATC when it becomes operational in late 2000.  Alliant
Energy is also reviewing the possible contribution of IESU's and IPC's
transmission assets to ATC as well.  Alliant Energy estimates the net book
value of such plant assets to approximate $220 million.  While Alliant Energy
will realize its proportionate share of ATC's earnings, it is not yet known
what the overall financial impact of Alliant Energy's participation in ATC
will be.

Minnesota - IPC is subject to regulation by the MPUC.  The MPUC established an
- ---------
Electric Competition Working Group in April 1995.  On October 28, 1997, the
Working Group issued a report and recommendations on retail competition.  The
MPUC reviewed the report and directed its staff to develop an electric utility
restructuring plan and timeline.  The MPUC has recently solicited comments on
restructuring principles from stakeholders in the process.  It does not appear
that any comprehensive restructuring legislation will be passed in 2000.  The
MPUC has also initiated Docket E-999/CI-1261 to investigate the appropriate
classification of transmission assets in Minnesota.

Illinois - WP&L and IPC are subject to regulation by the ICC.  In December
- --------
1997, the State of Illinois passed electric deregulation legislation requiring
customer choice of electric suppliers for non-residential customers with loads
of four MW or larger and for approximately one-third of all other
non-residential customers starting October 1, 1999.  All remaining
non-residential customers will be eligible for customer choice beginning

                                       30
<PAGE>

December 31, 2000 and all residential customers will be eligible for customer
choice beginning May 1, 2002.  The new legislation is not expected to have a
significant impact on Alliant Energy's financial condition or results of
operations given the relatively small size of Alliant Energy's Illinois
operations.  As of December 31, 1999, no eligible Alliant Energy customer had
selected another electric supplier.

Accounting Implications
Each of the utilities complies with the provisions of SFAS 71, "Accounting for
the Effects of Certain Types of Regulation."  SFAS 71 provides that
rate-regulated public utilities record certain costs and credits allowed in
the rate making process in different periods than for non-regulated entities.
These are deferred as regulatory assets or regulatory liabilities and are
recognized in the consolidated statements of income at the time they are
reflected in rates.  If a portion of the utility subsidiaries' operations
becomes no longer subject to the provisions of SFAS 71 as a result of
competitive restructurings or otherwise, a write-down of related regulatory
assets and possibly other charges would be required, unless some form of
transition cost recovery is established by the appropriate regulatory body
that would meet the requirements under generally accepted accounting
principles for continued accounting as regulatory assets during such recovery
period.  In addition, each utility subsidiary would be required to determine
any impairment of other assets and write-down any impaired assets to their
fair value.  The utility subsidiaries believe they currently meet the
requirements of SFAS 71 and will continue to monitor and assess this as the
various utility industry restructuring initiatives progress.

Positioning for a Competitive Environment
Alliant Energy and its subsidiaries cannot currently predict the long-term
consequences of the competitive and restructuring issues described above on
their financial condition or results of operations.  The major objective is to
allow the company to compete successfully in a competitive, deregulated
utility industry.  The strategy for dealing with these emerging issues
includes seeking growth opportunities, forming strategic alliances with other
energy-related businesses, continuing to offer quality customer service,
initiating ongoing cost reductions and productivity enhancements and
developing new products and services.

As competitive forces shape the energy-services industry, energy providers are
being challenged to increase growth and profits.  Because Alliant Energy
expects consumption of electricity and natural gas to grow only modestly
within Alliant Energy's domestic utility service territories, Alliant Energy
has entered several energy-services markets that it expects will provide
opportunities for new sources of growth.  Alliant Energy, through its
subsidiary Resources, has established new distinct platforms to complement its
existing non-regulated investments, which are designed to meet customer
needs.  These platforms and existing investments include:

      Investments: Resources' existing investments include an oil and gas
      -----------
      production company, a short-line railroad, a barge company, an
      affordable housing company, various real estate joint ventures and an
      equity stake in an independent telecommunications provider.
      International: International is a partner in developing, or seeking to
      -------------
      develop, energy generation and infrastructure in New Zealand, Australia,
      China, Mexico and Brazil, markets which have been selected because of
      their growth potential.
      Industrial Services: ISCO is a provider of energy and environmental
      --------------------
      services designed to maximize productivity for industrial and large
      commercial customers.  This platform consists of four units: Energy
      Planning; Energy Management; Energy Applications, which provides
      facilities-based and commodities-based energy solutions; and RMT, Inc.,
      an environmental management and engineering firm with offices throughout
      the U.S. and the United Kingdom.
      Cargill-Alliant: Alliant Energy has an energy-trading joint venture with
      ---------------
      Cargill that combines the risk-management and commodity trading
      expertise of Cargill with Alliant Energy's low-cost electricity
      generation and transmission business experience.  Cargill-Alliant
      officially began operations in 1997 and has an initial term though
      October 2002.  The term automatically renews for successive five-year
      periods unless either party notifies the other at least one year prior
      to the then expiring term.
      Mass Markets: Resources is a provider of products and services designed
      -------------
      to meet the comfort, security and productivity needs of residential and
      small commercial customers.  Resources currently offers home appliance
      and furnace warranties and a variety of home energy, safety and security
      products through its "Power House" catalog.  Such products are marketed
      directly to customers, through the mail with the catalog and over the
      Internet.  Resources expects to continue pursuing opportunities in these
      markets, which it believes has a growth potential as industry
      deregulation allows more customers to choose their energy suppliers in
      an open market.

                                       31
<PAGE>

Alliant Energy believes that each of these platforms provide prospects for
growth both individually and collectively as the competitive energy-services
marketplace evolves.  Alliant Energy expects that these strategies will
contribute significantly to its annual earnings growth target of 4-6% from its
business operations.  Resources is expected to contribute 25% of such earnings
within the next 3-5 years.

Average number of common shares outstanding                      78,352           76,912             76,210
Earnings per average common share (basic and diluted)             $2.51            $1.26              $1.90
Pre-tax merger expenses                                            --            $54,045             $2,448
</TABLE>

The significant increase in Alliant Energy's 1999 earnings compared to 1998
was due to increased earnings from non-regulated operations of $0.60 per share
(of which $0.32 per share was attributable to sales of McLeod stock), higher
electric and natural gas margins from utility operations and lower utility
operation and maintenance expenses.  Higher depreciation (excluding hedge
losses in WP&L's nuclear decommissioning trust fund) and interest expenses
partially offset these items.  The 1998 results also included approximately
$54 million of pre-tax merger-related expenses ($0.45 per share).

The 1999 utility earnings were $161.1 million ($2.06 per share) compared to
$109.5 million ($1.42 per share) for 1998.  The increase in utility earnings
resulted primarily from higher electric and natural gas margins ($0.24 and
$0.04 per share, respectively), lower operation and maintenance expenses
($0.09 per share) and income realized from weather hedges ($0.04 per share).
Higher depreciation (excluding hedge losses in WP&L's nuclear decommissioning
trust fund) and interest expenses ($0.10 and $0.02 per share, respectively)
and a higher effective income tax rate ($0.02 per share) partially offset
these items.  The 1998 utility results included approximately $0.42 per share
of merger-related expenses.

Resources reported net income of $37.8 million ($0.48 per share) in 1999
compared to a net loss of $8.9 million (($0.12) per share) for 1998.  The 1999
earnings included gains realized from several asset sales, including
approximately 7% of Alliant Energy's investment in McLeod ($0.32 per share),
oil and gas properties at Whiting ($0.08 per share) and certain New Zealand
electric distribution investments ($0.05 per share).  Earnings from Alliant
Energy's electricity trading joint venture ($0.06 per share), improved
operating results from Whiting ($0.03 per share) and improved earnings from
Alliant Energy's other non-regulated businesses ($0.03 per share) also
contributed to the increased earnings.  The 1998 results for Resources also
included merger-related expenses ($0.03 per share).

The 1998 utility earnings were $109.5 million compared to $152.5 million for
1997.  The decrease in 1998 utility earnings resulted primarily from
merger-related expenses, higher purchased-power and transmission costs at
WP&L, a 15.7% decrease in retail natural gas sales largely due to milder
weather conditions in 1998 compared to 1997, a $9 million regulatory asset
write-off at IESU, increased expenses for Year 2000 readiness efforts, higher
insurance-related expenses and increased depreciation expenses.  These
decreases were partially offset by a 2% increase in retail electricity sales
volumes, largely due to continued economic growth within Alliant Energy's
service territory, lower purchased-power capacity costs at IESU and IPC,
reduced employee benefits costs and lower costs in 1998 due to merger-related
operating efficiencies.  A loss incurred on the disposition of an investment
in 1997 at IESU also enhanced the 1998 earnings compared to 1997.

                                       32
<PAGE>

Resources reported net losses of $8.9 million and $4.0 million in 1998 and
1997, respectively.  The increased loss in 1998 was due to merger-related
expenses, lower oil and gas prices at Whiting, continuing expenses for new
business development in international and domestic markets, higher interest
expense to fund Alliant Energy's growth and a modest loss from Alliant
Energy's electricity trading joint venture.  A tax benefit realized in 1997
from a donation of securities to Alliant Energy's charitable foundation also
contributed to the lower earnings in 1998 compared to 1997.  Increased
earnings from Alliant Energy's industrial services businesses as well as gains
realized on asset sales partially offset these items.

</TABLE>

Electric margin increased $18.1 million, or 2%, and $33.9 million, or 3%, for
1999 and 1998, respectively.  The 1999 increase was primarily due to separate
$15 million annual rate adjustments implemented at WP&L in July 1998 and March
1999 to recover higher purchased-power and transmission costs, a favorable $9
million change in estimate of Alliant Energy's utility services rendered but
unbilled at month-end based on refinements made to Alliant Energy's estimation
process in 1999 and an increase in retail sales of 3% due to more favorable
weather conditions and economic growth in the service territory.  Partially
offsetting these increases were reduced recoveries of approximately $14
million in concurrent and previously deferred expenditures for Iowa-mandated
energy efficiency programs, lower sales to off-system and wholesale customers,
higher purchased-power capacity costs in Iowa and $3.2 million of revenues
collected from WP&L customers in 1998 for a surcharge related to Kewaunee.
The recovery for energy efficiency programs in Iowa is in accordance with IUB
orders (a portion of these recoveries is offset as they are also amortized to
expense in other operation expense).  The lower sales to off-system and
wholesale customers were primarily due to lower wholesale customer contractual
commitments and transmission constraints.

The increase in electric margin for 1998 was primarily due to the increased
recovery of $26 million of concurrent and previously deferred expenditures for
Iowa-mandated energy efficiency programs, reduced purchased-power capacity
costs at IESU and IPC, higher sales volumes to retail customers and WP&L's
reliance on more costly purchased-power in the first six months of 1997 due to
various power plant outages, particularly Kewaunee.  The increased sales
volumes were primarily due to continued economic growth within the Alliant
Energy service territory.  These increases were partially offset by a lower
margin at WP&L and a rate decrease implemented at IPC in 1997.  The lower
margin at WP&L was due to the regulatory lag associated with the rate recovery
of higher purchased-power and transmission costs, a rate decrease implemented
in 1997 and lower off-system sales income.

IESU's and IPC's electric tariffs include EAC's that are designed to currently
recover the costs of fuel and the energy portion of purchased-power billings
(see Note 1(j) of the "Notes to Consolidated Financial Statements" for
discussion of the EAC).

</TABLE>

Gas margin increased $4.7 million, or 4%, and decreased $5.5 million, or 4%,
for 1999 and 1998, respectively.  The 1999 increase was primarily due to
higher retail sales due to customer growth and more favorable weather
conditions in 1999.  The sales increase was partially offset by decreased
recoveries of $2.6 million from the recovery of concurrent and previously
deferred energy efficiency expenditures for Iowa-mandated energy efficiency
program costs in accordance with IUB orders (a portion of these recoveries is
offset as they are also amortized to expense in other operation expense).
Refer to "Interest Expense and Other" for a discussion of income realized from
two gas weather hedges at WP&L in 1999.  The decrease in gas margin in 1998
was primarily due to a 12% decrease in Dth sales, largely due to milder
weather, and a rate reduction implemented in April 1997 at WP&L.  An increase
in revenues of $6.3 million from the recovery of energy efficiency
expenditures in Iowa and gas cost adjustments at IPC partially offset the
sales decrease.

IESU's and IPC's gas tariffs include PGA clauses that are designed to
currently recover the cost of utility gas sold (see Note 1(j) of the "Notes to
Consolidated Financial Statements" for a discussion of the PGA).

                           =========  =========  =========

The revenues for ISCO increased significantly in 1999 primarily due to the
second quarter 1999 acquisition of an oil gathering and transportation
business in Texas and increased demand for environmental and engineering
services.  Such increases were partially offset by reduced activity in the
energy marketing business.  The revenues for ISCO declined significantly in
1998 compared to 1997 primarily due to decreased low-margin gas marketing
activities and the transfer of the electricity trading business to the Cargill
joint venture in July 1997.  Alliant Energy's investment in the joint venture
is accounted for under the equity method of accounting.

                                ==========  =========   =========

Other operation expenses at the utility subsidiaries decreased $55 million in
1999 primarily due to the nonrecurrence of $34 million of merger-related
expenses incurred in 1998, lower energy efficiency expenses of $17 million in
Iowa, a 1998 write-off of $9 million of certain employee benefits related
regulatory assets at IESU, decreased transmission and distribution expenses,
lower operating costs at Alliant Energy's generating plants, reduced
insurance-related expenses and lower costs in 1999 due to merger-related
operating efficiencies.  The merger-related expenses were primarily for
employee retirements ($15 million), separations ($13 million) and relocations
($4 million).  These decreases were partially offset by higher costs for
employee incentive compensation, energy conservation expense at WP&L and
employee benefits.

Other operation expenses at ISCO increased $66 million in 1999 primarily due
to expenses associated with the acquisition of the oil gathering and
transportation business and the increased demand for environmental and
engineering services, partially offset by lower operation expenses in the
energy marketing business.  Other operation expenses at ISCO decreased $122
million in 1998 primarily due to the formation of the Cargill joint venture.

Other operation expenses at the utility subsidiaries increased $63 million in
1998 primarily due to the merger-related expenses, increased energy efficiency
expenses in Iowa, the regulatory asset write-off at IESU, higher
administrative and general expenses at WP&L, higher insurance-related expenses
and increased expenses for Year 2000 readiness efforts.  The increase was
partially offset by reduced employee benefit expenses, reduced energy
conservation expense at WP&L, lower costs resulting from merger-related
operating efficiencies and reduced nuclear operation expenses at IESU.  The
regulatory asset write-off resulted from IESU assessing in the fourth quarter
of 1998 how certain employee benefit costs were recovered in the rate making
process in Iowa.  Based on such review, IESU concluded it could no longer meet
the required "probable" standard for SFAS 71.

The 1999 decrease in maintenance expenses was primarily due to reduced nuclear
and transmission and distribution maintenance expenses.  Such decreases were
partially offset by increased expenses for Alliant Energy's Year 2000
readiness program and higher expenses at Alliant Energy's fossil-fueled
generating plants.  Maintenance expenses were flat in 1998 primarily due to
reduced expenses at fossil-fueled plants, which were virtually offset by
increased maintenance at the nuclear plants.

Depreciation and amortization expense decreased $0.4 million and increased
$19.8 million in 1999 and 1998, respectively.  The 1999 decrease was primarily
due to reduced earnings in WP&L's nuclear decommissioning trust fund (offset
entirely in "Miscellaneous, net"), lower depletion expense at Whiting and the
$3.2 million Kewaunee surcharge in 1998 at WP&L (recorded in depreciation and
amortization expense with a corresponding increase in revenues resulting in no
earnings impact).  These items were largely offset by increases in
depreciation expense due to utility property additions.  The increase in 1998
was due to utility property additions and the Kewaunee surcharge.

<PAGE>

Interest Expense and Other - Interest expense increased $6.9 million and $6.8
- --------------------------
million in 1999 and 1998, respectively, due to higher utility and
non-regulated borrowings.  Also contributing to the 1999 increase was higher
nuclear decommissioning trust fund interest expense at IESU, which was offset
entirely in "Miscellaneous, net."  Contributing to the 1998 increase was an
adjustment to decrease interest expense in 1997 relating to a tax audit
settlement at WP&L.

The accounting for earnings on the nuclear decommissioning trust funds results
in no net income impact.  Miscellaneous, net income increases for earnings on
the nuclear decommissioning funds at both WP&L and IESU.  In accordance with
their respective regulatory requirements, the corresponding offset is recorded
through depreciation expense at WP&L and interest expense at IESU.

Alliant Energy sold approximately 7% (1.4 million shares, as adjusted for
McLeod's 2-for-1 stock split in July 1999) of its investment in McLeod in
1999, resulting in pre-tax gains of approximately $40 million.

Miscellaneous, net income increased $35.2 million and decreased $13.2 million
in 1999 and 1998, respectively.  The 1999 increase was due to the following
factors:

(a)   $17 million of merger-related expenses incurred in 1998 for the services
      of Alliant Energy's advisors and costs related to Alliant Energy's
      merger-related name change.
(b)   Gains of $10 million and $6 million realized from the sales of several
      oil and gas properties at Whiting and certain New Zealand electric
      distribution investments, respectively.
(c)   A $7 million increase in pre-tax earnings from Alliant Energy's
      electricity trading joint venture.
(d)   $5 million of income realized from weather hedges at WP&L.  Refer to
      Note 11(d) of the "Notes to Consolidated Financial Statements" for a
      further discussion.
(e)   These items were partially offset by a decrease of $11 million in
      earnings on Alliant Energy's nuclear decommissioning trust funds.

The 1998 decrease in miscellaneous, net income was due to the merger-related
expenses and a modest loss from Alliant Energy's electricity trading joint
venture, partially offset by gains on asset sales in 1998.  The 1997 results
also included a loss incurred on the disposition of an investment at IESU.

Income  Taxes - The  effective  income tax rates for Alliant  Energy were 37.2%,
- -------------
36.0%  and  35.1%  in  1999,  1998  and  1997,  respectively.  See Note 6 of the
"Notes to Consolidated Financial Statements" for a discussion of the changes.

                           IESU RESULTS OF OPERATIONS

Overview - IESU's earnings available for common stock increased $4.5 million
- ---------
and $3.1 million in 1999 and 1998, respectively.  The increased earnings for
1999 were primarily due to $17 million of merger-related expenses in 1998, a
$9 million regulatory asset write-off in 1998, a change in estimate of IESU's
unbilled revenues and reduced maintenance expenses.  Such increases were
partially offset by higher depreciation and amortization expense, increased
administrative and general expenses and a higher effective income tax rate.
The increased earnings for 1998 were primarily due to a 2% increase in retail
electric sales volumes, largely due to continued economic growth in IESU's
service territory, lower purchased-power capacity costs, reduced employee
benefits costs and lower costs in 1998 due to merger-related operating
efficiencies.  A loss incurred on the disposition of an investment in 1997
also improved 1998 earnings compared to 1997.  Partially offsetting the higher
1998 earnings were merger-related expenses, the regulatory asset write-off
described above, decreased retail natural gas sales resulting from milder
weather, increased depreciation and amortization expenses and increased
expenses for Year 2000 readiness efforts.

</TABLE>

Electric margin decreased $3.0 million, or 1%, and increased $31.1 million, or
7%, for 1999 and 1998, respectively.  The 1999 decrease was primarily due to
reduced recoveries of approximately $4 million in concurrent and previously
deferred expenditures for Iowa-mandated energy efficiency programs and
increased purchased-power capacity costs.  The recovery for energy efficiency
programs in Iowa is in accordance with IUB orders (a portion of these
recoveries is offset as they are also amortized to expense in other operation
expense).  Sales for resale decreased significantly in 1999 primarily due to
various resale customers of IESU selecting another utility as their
electricity provider effective in early 1999.  The loss of such customers has
not had a material impact on IESU's electric margins.  Sales to retail
customers increased primarily due to continued economic growth in IESU's
service territory and more favorable weather conditions.  The 1999 electric
margin also benefited from a favorable $5 million change in estimate of IESU's
utility services rendered but unbilled at month-end based on refinements made
to IESU's estimation process in 1999.

The 1998 increase was primarily due to the increased recovery of approximately
$15 million of concurrent and previously deferred expenditures for
Iowa-mandated energy efficiency programs, increases in sales volumes to retail
customers due to economic growth in the service territory and reduced
purchased-power capacity costs.  Sales for resale increased significantly for
1998 as a result of the implementation of a merger-related joint sales
agreement during the second quarter of 1998 (off-system sales revenues are
passed through IESU's energy adjustment clause and therefore have no impact on
electric margin).  Refer to "Liquidity and Capital Resources - Rates and
Regulatory Matters" for a further discussion.

IESU's electric tariffs include EAC's that are designed to currently recover
the costs of fuel and the energy portion of purchased-power billings.  Refer
to Note 1(j) of Alliant Energy's "Notes to Consolidated Financial Statements"
for discussion of the EAC.

</TABLE>

Gas margin increased $0.9 million, or 2%, and decreased $0.2 million for 1999
and 1998, respectively.  The 1999 increase was primarily due to increased
retail sales from more favorable weather conditions in 1999.  The decrease in
1998 was primarily from reduced sales as a result of milder weather, which was
substantially offset by the increased recovery of $4.2 million of concurrent
and previously deferred energy efficiency expenditures for Iowa-mandated
energy efficiency program costs in accordance with IUB orders (a portion of
these recoveries is offset as they are also amortized to expense in other
operation expenses).

IESU's gas tariffs include PGA clauses that are designed to currently recover
the cost of gas sold.  Refer to Alliant Energy's Note 1(j) of the "Notes to
Consolidated Financial Statements" for discussion of the PGA.

Other Operating Expenses - IESU's other operation expenses decreased $13.5
- ------------------------
million and increased $26.5 million for 1999 and 1998, respectively.  The 1999
decrease was primarily due to $10.5 million of merger-related expenses in
1998, a $9 million regulatory asset write-off in 1998, a $4 million decrease
in energy efficiency expenses and merger-related operating efficiencies
realized in 1999.  The merger-related expenses were primarily for employee
retirements, separations and relocations.  The regulatory asset write-off
resulted from IESU assessing in the fourth quarter of 1998 how certain
employee benefit costs were recovered in the rate making process in Iowa.
Based on such review, IESU concluded it could no longer meet the required
"probable" standard for SFAS 71.  Such decreases were partially offset by
increased costs for employee incentive compensation and higher employee
benefit costs.  The 1998 increase was primarily due to higher merger-related
expenses, increased energy efficiency expenses, the regulatory asset write-off
mentioned above and increased Year 2000 readiness costs.  These items were
partially offset by lower nuclear operation expenses, reduced employee pension
and benefit costs and lower costs resulting from merger-related operating
efficiencies.

Maintenance expenses decreased $3.5 million and $1.8 million in 1999 and 1998,
respectively.  The decrease in 1999 was primarily due to reduced nuclear
maintenance expenses and lower transmission and distribution maintenance
expenses, partially offset by increased Year 2000 readiness costs and higher
fossil-fueled maintenance expenses.  The decrease in 1998 was due to reduced
fossil-fueled maintenance expenses, which were partially offset by higher
nuclear maintenance expenses.

Depreciation and amortization expenses increased $7.1 million and $4.2 million
for 1999 and 1998, respectively, primarily due to property additions and
amortization of software.

                                       38
<PAGE>

Interest Expense and Other - Interest expense decreased $0.5 million and $0.4
- --------------------------
million in 1999 and 1998, respectively.  The 1999 decrease was primarily due
to lower average amounts of debt outstanding which was partially offset by
higher nuclear decommissioning trust fund interest expense, which was offset
entirely in "Miscellaneous, net."

The accounting for earnings on the nuclear decommissioning trust funds results
in no net income impact.  Miscellaneous, net income increases for earnings on
the trust fund and the corresponding offset is recorded as interest expense.

Miscellaneous, net income increased $6.4 million and decreased $0.3 million
for 1999 and 1998, respectively.  The increase in 1999 resulted primarily from
$6.0 million of merger-related expenses in 1998 and higher nuclear
decommissioning trust fund earnings, which were partially offset by a gain on
an asset sale in 1998.  The 1998 decrease resulted primarily from
merger-related expenses, which were substantially offset by the loss incurred
on disposition of an investment in 1997 and a gain on an asset sale in 1998.

Income Taxes - The effective income tax rates were 42.6%, 40.1% and 41.8% in
- ------------
1999, 1998 and 1997, respectively.  See Note 6 of the "Notes to Consolidated
Financial Statements" for a discussion of the changes.

                           WP&L RESULTS OF OPERATIONS

Overview - WP&L's earnings available for common stock increased $35.3 million
- ---------
and decreased $35.7 million in 1999 and 1998, respectively.  The increased
earnings for 1999 were primarily due to $17.3 million of merger-related
expenses in 1998, higher electric and natural gas margins, reduced other
operation and maintenance expenses and income realized from weather hedges.
Such increases were partially offset by increased depreciation and
amortization expense (excluding hedge losses in WP&L's nuclear decommissioning
trust fund) and higher interest expense.  The decreased earnings for 1998 were
primarily due to merger-related expenses, higher purchased-power and
transmission costs, higher depreciation and amortization expenses, decreased
retail natural gas sales largely due to milder weather, higher
insurance-related expenses, higher interest expense and a higher effective tax
rate.  These decreases were partially offset by a 3% increase in retail
electric sales volumes, largely due to continued economic growth in the
service territory, reduced employee pension and benefit costs and lower costs
in 1998 due to merger-related operating efficiencies.

</TABLE>

Electric margin increased $28.2 million, or 7%, and decreased $11.6 million,
or 3%, during 1999 and 1998, respectively.  The 1999 increase was primarily
due to separate $15 million annual rate adjustments implemented at WP&L in

                                       39
<PAGE>

July 1998 and March 1999 to recover higher purchased-power and transmission
costs.  An increase in retail sales of 3% due to more favorable weather and
economic growth within WP&L's service territory also contributed to the
increase.  Partially offsetting the 1999 increase were lower sales to
off-system and wholesale customers due to transmission constraints and
decreased contractual commitments and $3.2 million of revenues collected in
1998 for a surcharge related to Kewaunee.

The 1998 decline in margin was due to regulatory lag associated with rate
recovery of higher purchased-power and transmission costs, a rate decrease of
2.4% implemented in April 1997 and lower off-system sales income.  These items
were partially offset by WP&L's reliance on more costly purchased-power in the
first six months of 1997 due to various power plant outages, particularly
Kewaunee, and a 3% increase in retail sales.

</TABLE>

Gas margin increased $6.4 million, or 13%, and declined $6.3 million, or 11%,
during 1999 and 1998, respectively.  The 1999 increase was due to increased
sales resulting from customer growth of approximately 2% and more favorable
weather conditions in 1999.  The 1998 decrease was primarily due to a
reduction in sales resulting from milder weather and an average retail rate
reduction of 2.2% implemented in April 1997.  Refer to Note 1(i) of Alliant
Energy's "Notes to Consolidated Financial Statements" for discussion of an
accounting change implemented in 1998.  Refer to "Interest Expense and Other"
for a discussion of income realized from two gas weather hedges in 1999.

Refer to Note 1(j) of Alliant Energy's "Notes to Consolidated Financial
Statements" for a discussion of a gas cost adjustment mechanism in place at
WP&L.  The impact on the results of operations from such mechanism was not
significant in any of the periods presented.

Other Operating Expenses - Other operation expenses decreased $17.2 million
- ------------------------
and increased $12.3 million for 1999 and 1998, respectively.  The 1999
decrease was primarily due to $11.2 million of merger-related expenses in 1998
for employee retirements, separations and relocations, reduced
insurance-related expenses, lower operating costs at WP&L's generating plants,
lower transmission and distribution expenses and lower costs due to
merger-related operating efficiencies.  Such items were partially offset by
increased costs for energy conservation, employee incentive compensation and
employee benefits expenses.  The 1998 increase was primarily due to
merger-related expenses, higher insurance-related expenses and an increase in
other administrative and general expenses.  Such items were partially offset
by reduced employee pension and benefits expenses, reduced conservation
expense and lower costs from merger-related operating efficiencies.

Maintenance expenses decreased $4.3 million in 1999.  The decrease was
primarily due to lower nuclear expenses and reduced transmission and
distribution maintenance expenses.  Such decreases were partially offset by
increased expenses associated with Year 2000 readiness efforts.

                                       40
<PAGE>

Depreciation and amortization expense decreased $6.2 million and increased
$14.9 million for 1999 and 1998, respectively.  The 1999 decrease was due to
reduced earnings in the nuclear decommissioning trust fund (offset entirely in
"Miscellaneous, net") and the $3.2 million Kewaunee surcharge in 1998.  These
items were partially offset by the impact of property additions.  The 1998
increase was due to property additions, higher Kewaunee depreciation (refer to
"Liquidity and Capital Resources - Capital Requirements - Nuclear Facilities"
for additional information) and the Kewaunee surcharge.

The accounting for earnings on the nuclear decommissioning trust funds results
in no net income impact.  Miscellaneous, net income is increased for earnings
on the trust fund, which is offset in depreciation expense.

Interest Expense and Other - Interest expense increased $4.4 million and $4.0
- --------------------------
million in 1999 and 1998, respectively.  The 1999 increase was primarily due
to higher short-term borrowings and the 1998 increase was primarily due to an
adjustment to decrease interest expense in 1997 relating to a tax audit
settlement and increased borrowings during 1998.

Miscellaneous, net income decreased $3.0 million and $2.7 million in 1999 and
1998, respectively.  The 1999 decrease was primarily due to lower earnings on
the nuclear decommissioning trust fund, partially offset by $6.1 million of
merger-related expenses in 1998 and pre-tax income of $5 million recognized in
1999 associated with the settlement of gas weather hedges.  See Note 11(d) of
the "Notes to Consolidated Financial Statements" for additional information
relating to the gas weather hedges.  The 1998 decrease was primarily due to
merger-related expenses, which was partially offset by higher earnings on the
nuclear decommissioning trust fund.

Income Taxes - The effective income tax rates were 39.2%, 41.0% and 37.0% in
- -------------
1999, 1998 and 1997, respectively.  See Note 6 of the "Notes to Consolidated
Financial Statements" for a discussion of the changes.

                        LIQUIDITY AND CAPITAL RESOURCES

Cash flows from operating activities at Alliant Energy decreased $45 million
for the year ended December 31, 1999, compared with the same period in 1998,
primarily due to changes in working capital.  Cash flows used for financing
activities decreased $161 million for the year ended December 31, 1999,
compared with the same period in 1998, primarily as a result of changes in the
amount of debt outstanding.  Cash flows used for investing activities
increased $39 million for the year ended December 31, 1999, compared with the
same period in 1998, due to increased levels of construction and acquisition
expenditures, which were partially offset by increased proceeds from
dispositions of assets.

Cash flows from operating activities at IESU decreased $44 million for the
year ended December 31, 1999, compared with the same period in 1998, primarily
due to changes in working capital.  Cash flows used for financing activities
increased $71 million for the year ended December 31, 1999, compared with the
same period in 1998, due to increased common stock dividends in 1999 as no
dividend payments were made in the last three quarters of 1998 due to
merger-related tax considerations.  As a result, the dividend payment in the
first quarter of 1999 was larger than IESU's historical quarterly payment.
Cash flows used for investing activities decreased $6 million for the year
ended December 31, 1999, compared with the same period in 1998, due to
decreased levels of construction expenditures.

Cash flows from operating activities at WP&L decreased $14 million for the
year ended December 31, 1999, compared with the same period in 1998, primarily
due to changes in working capital, partially offset by higher net income.
Cash flows used for financing activities decreased $34 million for the year
ended December 31, 1999, compared with the same period in 1998, primarily due
to a capital contribution of $30 million from Alliant Energy.  Cash flows used
for investing activities increased $17 million for the year ended December 31,
1999, compared with the same period in 1998, primarily due to increased
construction expenditures.

Future Considerations
The capital requirements of Alliant Energy are primarily attributable to its
utility subsidiaries' construction and acquisition programs, its debt
maturities and business opportunities of Resources.  It is anticipated that
future capital requirements of Alliant Energy will be met by cash generated
from operations, sale of investments and external financing.  The level of
cash generated from operations is partially dependent upon economic

                                       41
<PAGE>

conditions, legislative activities, environmental matters and timely
regulatory recovery of utility costs.  Alliant Energy's liquidity and capital
resources will be affected by costs associated with environmental and
regulatory issues.  Emerging competition in the utility industry could also
impact Alliant Energy's liquidity and capital resources, as discussed
previously in the "Utility Industry Outlook" section.

Alliant Energy had certain off-balance sheet financial guarantees and
commitments outstanding at December 31, 1999.  They generally consist of
third-party borrowing arrangements and lending commitments, guarantees of
financial performance of syndicated affordable housing properties and
guarantees relating to Alliant Energy's electricity trading joint venture.
Refer to Note 12(d) of the "Notes to Consolidated Financial Statements" for
additional details.

Under PUHCA, certain investments of Alliant Energy in exempt wholesale
generators and foreign utility companies are limited to 50% of Alliant
Energy's consolidated retained earnings.  Alliant Energy is pursuing making the
necessary regulatory filings requesting an increase in this limitation.  Under
WUHCA, there historically was an asset cap provision that had generally
limited non-utility assets in a utility holding company to 25% of utility
assets.  This provision limited Alliant Energy's ability to make additional
investments in its non-utility businesses.  The Reliability 2000 legislation
that was enacted in Wisconsin in 1999 provides Wisconsin utility holding
companies significant asset cap relief once they meet certain conditions
relating to the formation of a transmission company, as discussed in the
"Utility Industry Outlook" section.  Alliant Energy believes it has met all
such conditions and is now operating under the new law.  Under the provisions
of the new law, assets related to the provision of various energy-related,
environmental engineering and telecommunications services are no longer
included in the calculation of either utility or non-utility assets.

Alliant Energy expects to pursue various potential business development
opportunities, including international as well as domestic investments, and is
devoting resources to such efforts.  Foreign investments may carry a higher
level of risk than Alliant Energy's traditional domestic utility investments
or Resources' domestic investments.  Such risks could include foreign
government actions, foreign economic and currency risks and others.  It is
anticipated that Alliant Energy will strive to select investments where the
international and other risks are both understood and manageable.  At December
31, 1999, Resources had approximately $198 million of investments in foreign
entities.  At December 31, 1999, IESU, WP&L and IPC did not have any foreign
investments.

On February 1, 2000, Resources completed a private placement of exchangeable
senior notes due 2030, which were issued in the original aggregate principal
amount of $402.5 million.  The exchangeable senior notes have an interest rate
of 7.25% through February 15, 2003 and 2.5% thereafter.  The exchangeable
senior notes are exchangeable for cash based upon a percentage of the value of
McLeod Class A Common Stock.  Alliant Energy has agreed to fully and
unconditionally guarantee the payment of principal and interest on the
exchangeable senior notes.  The proceeds will be used to repay commercial
paper issued to capitalize Resources' wholly-owned exempt telecommunications
company and, indirectly through an internal transfer of assets, to assist in
funding the recent investment in Brazil, as well as for general corporate
purposes.

The exchangeable senior notes may have certain accounting consequences for
Alliant Energy that may affect reported earnings.  As disclosed in Note 10 of
the "Notes to Consolidated Financial Statements," Alliant Energy records its
investment in McLeod stock at its fair value, with changes in fair value, net
of income tax effects, recorded directly to the common equity section of the
Consolidated Balance Sheets as a component of "Accumulated other comprehensive
income."  Any such changes in fair value are reflected in current earnings
only at the time they are actually realized through a sale.  However,
applicable accounting rules require Alliant Energy to record in its
Consolidated Statements of Income any increase or decrease in the settlement
value (i.e., the amount payable upon maturity) of the exchangeable senior
notes that results from changes in the market value of McLeod stock.  The
settlement value of the exchangeable senior notes at any point in time is
generally (assuming no deferrals of interest payments) the higher of: (a) the
original principal amount plus accrued interest less cash dividends or other
distributions on the McLeod stock; or (b) the current market value of the
shares of McLeod stock attributable to the exchangeable senior notes.
Accordingly, any increase or decrease in the settlement value of the
exchangeable senior notes will be recorded as subtractions from, or additions
to, Alliant Energy's reported net income.

                                       42

The market price of the McLeod stock has been volatile and has fluctuated over
a wide range since the initial public offering.  A significant increase in the
market value of McLeod stock would significantly decrease Alliant Energy's
reported net income.  Similarly, a significant decrease in the market value of
McLeod stock would significantly increase Alliant Energy's reported net
income, subject to the condition that the settlement value of the exchangeable
senior notes will not be reduced below the original principal amount plus
accrued interest less cash dividends or other distributions on the McLeod
stock.  These increases and decreases in reported investment income in Alliant
Energy's Consolidated Statements of Income will be non-cash in nature and will
be reflected on Alliant Energy's Consolidated Balance Sheets as increases and
decreases in long-term debt.  Alliant Energy would recognize a non-cash charge
to net income of approximately $3.3 million for each $1/share increase in
McLeod's stock price above $77.23/share as relates to the 5.2 million shares
of McLeod stock attributable to the exchangeable senior notes.  This impact on
earnings will be mitigated somewhat once Alliant Energy adopts SFAS 133,
"Accounting for Derivative Instruments and Hedging Activities," as discussed
further below.

Alliant Energy may choose to adopt SFAS 133 early.  See "Other Matters -
Accounting Pronouncements" for additional information relating to SFAS 133.
SFAS 133 will require Alliant Energy to split the value of the exchangeable
senior notes into a debt component and a derivative component.  Any changes in
the fair value of the derivative component subsequent to the SFAS 133 adoption
date will be reflected as an increase or decrease in Alliant Energy's reported
net income.  At the date of initial adoption, SFAS 133 provides Alliant Energy
a one-time ability to transfer any of Alliant Energy's available-for-sale
securities, including a portion of its shares of McLeod stock, to the trading
category.  At the date of any such transfer from available-for-sale to
trading, Alliant Energy would recognize in income the appreciation in the
shares transferred.  Although Alliant Energy is not required to hold a number
of shares of McLeod stock equal to the number of exchangeable senior notes
outstanding, if Alliant Energy does so and if Alliant Energy elects to make
this transfer from available-for-sale to trading, changes subsequent to the
SFAS 133 adoption date in the fair value of the shares of McLeod stock so
transferred will be reflected as an increase or decrease in Alliant Energy's
reported net income.  Changes in the market value of the McLeod stock are
expected to at least partially offset changes in the fair value of the
derivative component of the exchangeable senior notes; however, there may be
periods with significant non-cash increases or decreases to Alliant Energy's
net income pertaining to the exchangeable senior notes and the related shares
of McLeod stock.

On January 25, 2000, Resources acquired a stake in four Brazilian electric
utilities serving more than 820,000 customers for a total investment of
approximately $347 million.  As part of this investment, Resources acquired a
49.1% ownership interest in Companhia Forca e Luz Cataguazes-Leopoldina
(Cataguazes), an electric utility.  Cataguazes owns a majority stake in CENF,
another electric utility company, as well as a majority interest in Energisa
S.A., an energy development company.  As part of the same investment,
Resources directly acquired a 45.6% interest in Energisa S.A. itself, which
holds majority stakes in two regulated utilities (Energipe and Celb).  As part
owner of Cataguazes, Resources will hold both indirect and direct interests in
Energisa S.A.  The investment is anticipated to dilute Alliant Energy's
earnings per share by approximately 3% in 2000, with positive contributions to
earnings expected in subsequent years.  Resources, through its wholly owned
subsidiary, International, initially financed the Brazil investment with cash
made available through the internal transfer of existing non-regulated
corporate assets.  Resources has entered into a shareholders agreement with
the Brazilian companies, which would allow it to name two directors to the
boards of each company and its subsidiaries.  The agreement will also provide
Resources with a role in selecting each company's management team, along with
voting rights relating to critical issues at the Brazilian companies and their
subsidiaries.  The investment will be accounted for under the equity method.

Alliant Energy entered into an agreement in November 1998, as amended, with
McLeod whereby Alliant Energy's ability to sell the McLeod stock is subject to
various restrictions.  The agreement provides that until December 31, 2001,
Alliant Energy and its affiliates generally may not sell or otherwise dispose
of shares of McLeod stock beneficially owned by Alliant Energy and its
affiliates, other than to a subsidiary of Alliant Energy, without the prior
written consent of the Board of Directors of McLeod.  However, the amended
agreement provides that the Board of Directors of McLeod may permit Alliant
Energy and its affiliates to sell a specified number of shares of McLeod stock
per quarter during specified time periods.  In addition, if Alliant Energy and
its affiliates are not provided the opportunity to sell, on an annual basis,
an aggregate number of shares of McLeod stock equal to 15% of the shares of
McLeod stock owned by Alliant Energy and its affiliates as of December 31,
1998, then Alliant Energy may terminate the amended November 1998 agreement.

In the first quarter of 2000, the Alliant Energy Board of Directors approved a
draft Agreement and Plan of Merger to merge IESU and IPC.  The new company
will be named Interstate Power and Light Company and it is anticipated the
merger will be completed by late 2000 or early 2001.  Alliant Energy expects
to be able to achieve cost savings and enhanced customer service from the
merger.

Financing and Capital Structure
Access to the long-term and short-term capital and credit markets, and costs
of external financing, are dependent on creditworthiness.  The debt ratings of
Alliant Energy and certain subsidiaries by Moody's and Standard & Poor's are
as follows:
<TABLE>

</TABLE>

(a) Resources' debt is fully and unconditionally guaranteed by Alliant Energy.
(b) IESU, WP&L and IPC participate in a utility money pool that is funded,
   as needed, through the issuance of commercial paper by Alliant Energy.
   Interest expense and other fees are allocated based on borrowing amounts.
   The PSCW has restricted WP&L from lending money to non-utility affiliates
   and non-Wisconsin utilities.  As a result, WP&L is prohibited from lending
   money to the utility money pool but is able to borrow money from the
   utility money pool.

On November 9, 1999, Resources issued $250 million of 7-3/8% senior notes due
2009 in a private placement.  The notes are fully and unconditionally
guaranteed by Alliant Energy.  The net proceeds from the debt offering have
been used to repay outstanding commercial paper, as it becomes due, that has
been backed by Resources' 3-Year Credit Agreement.

Other than periodic sinking fund requirements, which will not require
additional cash expenditures, the following long-term debt (in millions) will
mature prior to December 31, 2004:

  IESU     WP&L       Alliant Energy-Parent     Resources    IPC    Total
- ---------------------------------------------------------------------------
 $137.4    $63.9             $24.0               $12.6       $1.0   $238.9

Depending upon market conditions, it is currently anticipated that a majority
of the maturing debt will be refinanced with the issuance of long-term
securities.

On August 24, 1999, WP&L filed an application with the PSCW for authority to
issue up to $100 million of debentures for the purpose of refinancing existing
debt.  Approval was granted in February 2000 and the senior unsecured
debentures were issued in March 2000 at a fixed interest rate of 7-5/8%, due
2010.  The amount of short-term borrowings authorized by the PSCW will be
reduced by the same $100 million.

On November 25, 1998, IESU and IPC received authority from the SEC under PUHCA
to issue $200 million and $80 million of long-term debt securities,
respectively.  The companies continually evaluate their future financing needs
and will make any necessary regulatory filings as needed.

The various charter provisions of the entities identified below authorize and
limit the aggregate amount of additional shares of Cumulative Preferred Stock
and Cumulative Preference Stock that may be issued.  At December 31, 1999, the
companies could have issued the following additional shares of Cumulative
Preferred or Preference Stock:

                          IESU         WP&L          IPC
                        -----------------------------------
Cumulative Preferred    100,000     2,700,775     1,238,619
Cumulative Preference   700,000         --         2,000,000

                                       44
<PAGE>

For interim financing, IESU, WP&L and IPC were authorized by the applicable
federal or state regulatory agency to issue short-term debt at December 31,
1999 as follows (in millions):

                                             IESU      WP&L      IPC
                                           -----------------------------
Regulatory authorization                     $150      $128      $50
Short-term debt outstanding - money pool      $57      $126      $39


At December 31, 1999, there was no short-term debt outstanding with external
parties at the utility subsidiaries.  In addition to the $222 million of
commercial paper Alliant Energy issued to fund the utility money pool and $139
million of commercial paper at Resources, Alliant Energy had an additional $64
million of short-term debt outstanding at December 31, 1999.  In addition to
providing for ongoing working capital needs, this availability of short-term
financing provides the companies flexibility in the issuance of long-term
securities.  The level of short-term borrowing fluctuates based on seasonal
corporate needs, the timing of long-term financing and capital market
conditions.  To maintain flexibility in its capital structure and to take
advantage of favorable short-term rates, IESU and WP&L also use proceeds from
the sale of accounts receivable and unbilled revenues to finance a portion of
their long-term cash needs.  Alliant Energy anticipates that short-term debt
will continue to be available at reasonable costs due to current ratings by
independent utility analysts and credit rating services.

In December 1999, Alliant Energy, IESU, WP&L and IPC filed an application with
the SEC for approval of a combined accounts receivable program whereby each
utility will sell their respective receivables through wholly-owned special
purpose entities to an affiliated financing entity, which in turn will sell
the receivables to an outside investor.  The new program would replace the
existing programs for IESU and WP&L, and would function the same in most
respects.  Approvals from the SEC and the necessary state commissions are
expected in the second quarter of 2000.

Resources is a party to a revolving 3-Year Credit Agreement with various
banking institutions.  The agreement extends through October 2000, with
one-year extensions available upon agreement by the parties.  Unused borrowing
availability under this agreement is also used to support Resources'
commercial paper program.  A combined maximum of $450 million of borrowings
under this agreement and the commercial paper program may be outstanding at
any one time.  Interest rates and maturities are set at the time of
borrowing.  The rates are based upon quoted market prices and the maturities
are less than one year.  At December 31, 1999, Resources had $139 million of
commercial paper outstanding and backed by its 3-Year Credit Agreement with
discount rates ranging from 5.90%-6.32%.  Resources intends to continue
issuing commercial paper backed by this facility, and no conditions existed at
December 31, 1999, that would prevent the issuance of commercial paper or
direct borrowings on its bank lines.  As a result, Alliant Energy had been
classifying this debt as long-term.  However, since this agreement expires in
October 2000, beginning in October 1999 this debt (including commercial paper
backed by this facility) was classified as short-term.

In October 1999, Resources extended its revolving 364-Day Credit Agreement
with various banking institutions through October 2000.  The unborrowed
portion of this agreement is also used to support Resources' commercial paper
program.  A combined maximum of $150 million of borrowings under this
agreement and commercial paper backed by this facility may be outstanding at
any one time.  Interest rates and maturities are set at the time of
borrowing.  The rates are based upon quoted market prices and the maturities
are less than one year.  There were no borrowings outstanding under this
facility at December 31, 1999 and no conditions existed that would prevent the
issuance of commercial paper or direct borrowings under this agreement.

In addition to the aforementioned borrowing capability under Resources' credit
agreements, Alliant Energy has $250 million of committed bank lines of credit,
of which none was utilized at December 31, 1999, available for direct
borrowing or to support commercial paper.  Commitment fees are paid to
maintain these lines and there are no conditions which restrict the unused
lines of credit.  From time to time, Alliant Energy may borrow from banks and
other financial institutions on uncommitted "as-offered" credit lines in lieu
of commercial paper, and has agreements with several financial institutions
for such borrowings.  There are no commitment fees associated with these
agreements and there were no borrowings outstanding under these agreements at
December 31, 1999.

                                       45

Alliant Energy made a filing with the SEC in February 1999 under PUHCA to
provide Alliant Energy with, among other things, broad authorization over the
next three years to issue stock and debt, provide guarantees, acquire
energy-related assets and enter into interest rate hedging transactions.
Approval of the filing was received from the SEC in August 1999.

Given the above financing flexibility, including Alliant Energy's access to
both the debt and equity securities markets, management believes it has the
necessary financing capabilities in place to adequately finance its capital
requirements for the foreseeable future.

Capital Requirements
General - Capital expenditure and investment and financing plans are subject
- -------
to continual review and change.  The capital expenditure and investment
programs may be revised significantly as a result of many considerations,
including changes in economic conditions, variations in actual sales and load
growth compared to forecasts, requirements of environmental, nuclear and other
regulatory authorities, acquisition and business combination opportunities,
the availability of alternate energy and purchased-power sources, the ability
to obtain adequate and timely rate relief, escalations in construction costs
and conservation and energy efficiency programs.

Construction and acquisition expenditures for Alliant Energy for the year
ended December 31, 1999 and 1998 were $479 million and $372 million,
respectively.  Alliant Energy's anticipated construction and acquisition
expenditures for 2000 are estimated to be approximately $939 million,
consisting of approximately $484 million for energy-related international
investments, $319 million in its utility operations and $136 million for new
business development initiatives at Resources.  The significant increase in
construction and acquisition expenditures in international investments relates
to Resources' recent investment in Brazil.  See "Liquidity and Capital
Resources - Future Considerations" for information relating to the Brazil
investment.  Alliant Energy's anticipated utility construction and acquisition
expenditures for 2000 is made up of 46% for electric transmission and
distribution, 23% for electric generation, 17% for information technology and
14% for miscellaneous electric, gas, water and steam projects.  The level of
2000 domestic and international investments could vary significantly from the
estimates noted here depending on actual investment opportunities, timing of
the opportunities and the receipt of regulatory approvals to exceed
limitations in place under PUHCA.  It is expected that Alliant Energy will
spend approximately $1.4 billion on utility construction and acquisition
expenditures during 2001-2004, including expenditures to comply with NOx
emissions reductions in Wisconsin as discussed in "Other Matters -
Environmental."  It is expected that Resources will invest in energy products
and services in domestic and international markets, industrial services
initiatives and other strategic initiatives during 2001-2004.

IESU's construction and acquisition expenditures for the years ended December
31, 1999 and 1998 were $107 million and $115 million, respectively.  IESU's
anticipated construction and acquisition expenditures for 2000 are estimated
to be approximately $115 million, of which 45% is for electric transmission
and distribution, 26% for electric generation, 15% for information technology
and the remaining 14% represents miscellaneous electric, gas, steam and
general expenditures.  IESU's levels of utility construction and acquisition
expenditures are projected to be $127 million in 2001, $117 million in 2002,
$118 million in 2003 and $123 million in 2004.

WP&L's construction and acquisition expenditures for the years ended December
31, 1999 and 1998 were $132 million and $117 million, respectively.  WP&L's
anticipated construction and acquisition expenditures for 2000 are estimated
to be approximately $143 million, of which 45% is for electric transmission
and distribution, 25% for electric generation, 15% for information technology
and the remaining 15% represents miscellaneous electric, gas, water and
general expenditures.  WP&L's construction and acquisition expenditures are
projected to be $166 million in 2001, $181 million in 2002, $192 million in
2003 and $136 million in 2004, which include expenditures to comply with NOx
emissions reductions as discussed in "Other Matters - Environmental."

Alliant Energy anticipates financing utility construction expenditures during
2000-2004 through internally generated funds supplemented, when required, by
outside financing.  Funding of Resources' construction and acquisition
expenditures over that same period of time is expected to be completed with a
combination of external financings, sales of investments and internally
generated funds.

                                       46

Nuclear Facilities - Alliant Energy owns interests in two nuclear facilities,
- --------------------
Kewaunee and DAEC.  Kewaunee, a 532 MW pressurized water reactor plant, is
operated by WPSC and is jointly owned by WPSC (41.2%), WP&L (41.0%), and MG&E
(17.8%).  The Kewaunee operating license expires in 2013.  DAEC, a 535 MW
boiling water reactor plant, is operated by IESU which has a 70% ownership
interest in the plant.  The DAEC operating license expires in 2014.

On April 7, 1998, the PSCW approved WPSC's application for replacement of the
two steam generators at Kewaunee.  The total cost of replacing the steam
generators will be approximately $90.7 million, with WP&L's share of the cost
being approximately $37.2 million.  The replacement work originally planned
for the spring of 2000 is now scheduled for the fall of 2001 and will take
approximately 60 days.  The delay is attributable to the inability of the
steam generator manufacturer to meet the spring 2000 delivery schedule.
Delays in meeting the delivery schedule did not allow for steam generator
replacement to occur prior to the start of the summer weather in 2000.
Therefore, the decision was made to store the steam generators after they are
received and wait until the next scheduled refueling outage in the fall of
2001.  It is anticipated that the delay will not adversely impact the
reliability of Kewaunee in the interim.  Plans to shutdown the plant for a
spring 2000 refueling remain unchanged.

On July 2, 1998, the PSCW approved an agreement between the owners of Kewaunee
which provides for WPSC to assume the 17.8% Kewaunee ownership share currently
held by MG&E prior to work beginning on the replacement of steam generators.
On September 29, 1998, WPSC and MG&E finalized an arrangement in which WPSC
will acquire MG&E's 17.8% share of Kewaunee.  This agreement, the closing of
which is contingent upon regulatory approval and the steam generator
replacement in the fall of 2001, will give WPSC 59.0% ownership in Kewaunee.
After the change in ownership, WPSC and WP&L will be responsible for the
decommissioning of the plant.  WPSC and WP&L are discussing revisions to the
joint power supply agreement which will govern operation of the plant after
the ownership change takes place.  Prior to the July 2, 1998 PSCW decision,
the PSCW had directed the owners of Kewaunee to record depreciation and
decommissioning cost levels based on an expected plant end-of-life of 2002
versus a license end-of-life of 2013.  This was prompted by the uncertainty
regarding the expected useful life of the plant without steam generator
replacement.  This level of depreciation will remain in effect until the steam
generator replacement is completed at which time the entire plant will be
depreciated over 8.5 years using an accelerated method.

In February 1999, Alliant Energy, NSP, WPSC and WEPCO announced the formation
of the NMC to sustain long-term safety, optimize reliability and improve the
operational performance of their nuclear generating plants.  Combined, the NMC
members operate seven nuclear generating units at five plants.  In October
1999, Alliant Energy received approval from the SEC, under PUHCA, to form
Alliant Energy Nuclear LLC, whose purpose is solely to invest in the NMC.
Such investment has been made and Alliant Energy Nuclear LLC now has a 25%
ownership interest in the NMC.  In November 1999, the NMC members applied to
the NRC to allow the NMC to operate the plants owned or co-owned by the four
utilities.  Applications to the PSCW, MPUC and the SEC to allow the purchase
of operating services were also made at that time.  These approvals are
required if the applicable utilities choose to transfer their operating
license to, and take operating services from, the NMC.  As presently proposed,
the NMC would operate the plants, but the utilities would continue to own
their plants, be entitled to energy generated at the plants and retain the
financial obligations for the safe operation, maintenance and decommissioning
of the plants.

For additional information related to Kewaunee and DAEC, see Notes 1, 3, 10,
12 and 13 of the "Notes to Consolidated Financial Statements."  Refer to the
"Other Matters - Environmental" section for a discussion of various issues
impacting Alliant Energy's future capital requirements.

Rates and Regulatory Matters
FERC - In November 1997, as part of its merger approval, FERC accepted a
- ------
proposal by IESU, WP&L, and IPC, which provides for a four-year freeze on
wholesale electric prices beginning with the effective date of the merger.

In association with the merger, IESU, WP&L and IPC entered into a System
Coordination and Operating Agreement which became effective with the
consummation of the merger.  The agreement, which has been approved by the
FERC, provides a contractual basis for coordinated planning, construction,
operation and maintenance of the interconnected electric generation and

                                       47
<PAGE>

transmission systems of the three utility companies.  In addition, the
agreement allows the interconnected system to be operated as a single control
area with off-system capacity sales and purchases made to market excess system
capability or to meet system capability deficiencies.  Such sales and
purchases are allocated among the three utility companies based on procedures
included in the agreement.  The procedures were approved by both the FERC and
all state regulatory bodies having jurisdiction over these sales.

IESU - In September 1997, IESU agreed with the IUB to provide Iowa customers a
- ----
four-year retail electric and gas price freeze commencing on the effective
date of the merger.  The agreement excluded price changes due to
government-mandated programs (such as energy efficiency cost recovery), the
electric fuel adjustment clause and PGA clause and unforeseen dramatic changes
in operations.  In addition, the price freeze does not preclude a review by
either the IUB or OCA into whether IESU is exceeding a reasonable return on
common equity.  Refer to the "Utility Industry Outlook" section for a
discussion of legislation introduced in Iowa regarding restructuring the
electric utility industry.

In the first quarter of 2000, the OCA requested certain financial information
related to the electric utility operations within the state of Iowa for IESU.
IESU is in the process of preparing responses to the data requests.  While
IESU cannot predict the outcome of this process, such data requests could lead
to an effort by the OCA to seek an electric  rate reduction for IESU in Iowa.
IESU has received similar requests from the OCA in the past.

Under provisions of the IUB rules, IESU is currently recovering the costs it
has incurred for its energy efficiency programs.  Generally, the costs
incurred through July 1997 are being recovered over various four-year
periods.  Statutory changes implemented by the IUB in 1997 allowed IESU to
begin concurrent recovery of its prospective expenditures on August 1, 1997.
The implementation of these changes will gradually eliminate the regulatory
asset that was created under the prior rate making mechanism as these costs
are recovered.

WP&L - In connection with its approval of the merger, the PSCW accepted a WP&L
- ----
proposal to freeze rates for four years commencing on the effective date of
the merger.  A re-opening of an investigation into WP&L's rates during the
rate freeze period, for both cost increases and decreases, may occur only for
single events that are not merger-related and have a revenue requirement
impact of $4.5 million or more.  In addition, the electric fuel adjustment
clause and PGA clause are not affected by the rate freezes.

In  February  2000,  the PSCW  issued an order  allowing  WP&L to defer  certain
incremental  costs it incurs after February 16, 2000 relating to the development
of the ATC.

The retail electric rates are based in part on forecasted fuel and
purchased-power costs.  Under PSCW rules, Wisconsin utilities can seek
emergency rate increases if the annual costs are more than 3% higher than the
estimated costs used to establish rates.  In March 1998, WP&L requested an
electric rate increase to cover purchased-power and transmission costs that
had increased due to transmission constraints and electric reliability
concerns in the Midwest.  Effective July 16, 1998, the PSCW granted a retail
electric rate increase of $14.8 million annually.  In November 1998, WP&L
requested an electric rate increase to cover additional increases in
purchased-power and transmission costs.  In early March 1999, the PSCW granted
a retail electric rate increase of $14.5 million annually.  If WP&L's earnings
exceed its authorized return on equity, the incremental revenues collected
causing the excessive return are subject to refund.  In December 1999, WP&L
requested a $26 million retail electric rate increase to reflect higher
purchased power costs and to cover transmission costs that have increased due
to transmission constraints.  While the most current request is still pending,
WP&L anticipates receiving an order in the second quarter of 2000.

In May 1998, the PSCW approved the deferral by WP&L of certain costs
associated with its Year 2000 program.  In November 1998, WP&L filed for rate
recovery of the Wisconsin retail portion of its Year 2000 costs.  In
accordance with the order received from the PSCW, WP&L began deferring its
Year 2000 project costs, other than internal labor and associated overheads.
In November 1999, the PSCW allowed WP&L rate recovery of $6.3 million of its
Year 2000 program expenditures, but it denied rate recovery of the first $4.5
million.  These costs were expensed in 1999.  The PSCW's decision has been
appealed by certain intervenors in Dane County district court and such appeal
is pending.

                                       48

In January 1999, WP&L made a filing with the PSCW proposing to begin
deferring, on January 1, 1999, all costs associated with the EPA's required
NOx emission reductions.  In connection with a statewide docket to investigate
compliance issues associated with the EPA's NOx emission reductions, on March
30, 1999, the PSCW authorized deferral of all non-labor related costs incurred
after March 30, 1999.  However, the utilities are not allowed to defer costs
of replacement power associated with NOx compliance.  WP&L requested expedited
approval to start construction of NOx reduction investments at several
generating units operated by WP&L and in the third quarter of 1999 received
approval from the PSCW for limited NOx related expenditures at one of its
generating units.  WP&L has also requested recovery of all the NOx reduction
costs through a surcharge mechanism.  In March 2000, the PSCW issued an order
approving WP&L's NOx compliance plans and granted the recovery of costs
incurred to comply with EPA NOx regulations over ten years using a
straight-line depreciation method.  Recovery of such costs will begin with
rate changes after the rate freeze expires.  The depreciation lives will be
reviewed every two years.  Refer to the "Other Matters - Environmental"
section for a further discussion of the NOx issue.

In rate order UR-110, the PSCW approved new rates effective April 29, 1997.
On average, WP&L's retail electric rates under the new rate order declined by
2.4% and retail gas rates declined by 2.2%.

Refer to "Capital Requirements - Nuclear Facilities" for a discussion of
several PSCW rulings regarding Kewaunee.

IPC - In September 1997, IPC agreed with the IUB to provide Iowa customers a
- ---
four-year retail electric and gas price freeze commencing on the effective
date of the merger.  The agreement excluded price changes due to
government-mandated programs (such as energy efficiency cost recovery), the
electric fuel adjustment clause and PGA clause and unforeseen dramatic changes
in operations.  In addition, the price freeze does not preclude a review by
either the IUB or OCA into whether IPC is exceeding a reasonable return on
common equity.  IPC also agreed with the MPUC and ICC to four-year and
three-year rate freezes, respectively, commencing on the effective date of the
merger.  Refer to the "Utility Industry Outlook" section for a discussion of
legislation introduced in Iowa regarding restructuring the electric utility
industry.

IPC is also recovering its energy efficiency costs in Iowa in a similar manner
as IESU and began its concurrent cost recovery in October 1997.

Assuming capture of the merger-related synergies and no significant
legislative or regulatory changes negatively affecting its utility
subsidiaries, Alliant Energy does not expect the merger-related electric and
gas price freezes to have a material adverse effect on its financial condition
or results of operations.

                                 OTHER MATTERS

Year 2000
Alliant Energy had no significant embedded equipment, computer system or other
malfunctions during the critical December 31, 1999 to January 1, 2000 date
rollover or the February 28, 2000 to February 29, 2000 date rollover.  Alliant
Energy will continue to monitor for any supply chain issues into the second
quarter of 2000.

Alliant Energy's historical Year 2000 project expenditures were as follows
(incremental costs, in millions):

In addition, Alliant Energy estimates it incurred $7 million and $3 million in
1999 and 1998, respectively, of costs for internal labor and associated
overheads.  Alliant Energy does not expect to incur any significant
incremental costs in 2000 on its Year 2000 readiness program.  Refer to
"Liquidity and Capital Resources - Rates and Regulatory Matters" for a
discussion of the filing WP&L made with the PSCW for rate recovery of a
portion of its Year 2000 program costs.

Labor Issues
The status of the collective bargaining agreements at each of the utilities at
December 31, 1999 was as follows:

                                                  IESU     WP&L      IPC
                                                  ----------------------
Number of collective bargaining agreements          6        1        3

Percentage of workforce covered by agreements      61%      93%      83%


The collective bargaining agreements at Alliant Energy cover approximately 51%
of all Alliant Energy employees.  In 1999, eight agreements expired and four
of these agreements have been ratified and four are still being negotiated
(three at IPC and one at IESU).  The agreements still being negotiated have
been extended and represent 42% of employees covered under bargaining
agreements and 22% of total Alliant Energy employees.  In 2000, two contracts
expire representing approximately 1% of employees covered under bargaining
agreements and less than 1% of total Alliant Energy employees.  Alliant Energy
has not experienced any significant work stoppage problems in the past.  While
negotiations are continuing, Alliant Energy is currently unable to predict the
outcome of these negotiations.

Market Risk Sensitive Instruments and Positions
Alliant Energy's primary market risk exposures are associated with interest
rates, commodity prices, equity prices and currency exchange rates.  Alliant
Energy has risk management policies to monitor and assist in controlling these
market risks and uses derivative instruments to manage some of the exposures.

Interest Rate Risk - Alliant Energy is exposed to risk resulting from changes
- ------------------
in interest rates as a result of its issuance of variable-rate debt.  Alliant
Energy manages its interest rate risk by limiting its variable interest rate
exposure and by continuously monitoring the effects of market changes in
interest rates.  Alliant Energy has also historically used interest rate swap
and interest rate forward agreements to assist in the management of its
interest exposure.  If variable interest rates were to average 1% higher
(lower) in 2000 than in 1999, interest expense and pre-tax earnings would
increase (decrease) by approximately $5.1 million.  Comparatively, if variable
interest rates had averaged 1% higher (lower) in 1999 than in 1998, interest
expense and pre-tax earnings would have increased (decreased) by approximately
$4.5 million.  These amounts were determined by considering the impact of a
hypothetical 1% increase (decrease) in interest rates on the variable-rate
debt and related derivative instruments held by Alliant Energy as of December
31, 1999 and 1998.  In the event of significant interest rate fluctuations,
management would take actions to minimize the effect of such changes on
Alliant Energy's results of operations.  However, due to the uncertainty of
the specific actions that would be taken and their possible effects, the
sensitivity analysis assumes no change in Alliant Energy's financial structure.

Commodity Risk - Non-trading - Alliant Energy is exposed to the impact of
- ----------------------------
market fluctuations in the commodity price and transportation costs of
electricity, natural gas and oil products it markets.  Alliant Energy employs
established policies and procedures to manage its risks associated with these
market fluctuations including the use of various commodity derivatives.
Alliant Energy's exposure to commodity price risks in its utility business is
significantly mitigated by the current rate making structures in place for the
recovery of its electric fuel and purchased energy costs as well as its cost
of natural gas purchased for resale.  Refer to Note 1(j) of the "Notes to
Consolidated Financial Statements" for a further discussion.

From time to time, WP&L utilizes gas commodity swap arrangements for the
purpose of mitigating the impact of price fluctuations on gas purchased and
injected into storage during the summer months and withdrawn and sold at
current prices during the winter months.  The gas commodity swaps in place
approximate the forecasted storage withdrawal plan during this period.
Therefore, market price fluctuations that result in an increase or decrease in
the value of the physical commodity are offset by changes in the value of the
gas commodity swaps.  A 10% increase/decrease in the price of gas would have
an insignificant impact on the combined fair market value of the gas in
storage and related swap arrangements in place as of December 31, 1999 and
1998.

Whiting is exposed to market risk in the pricing of its oil and gas
production.  Historically, prices received for oil and gas production have
been volatile because of seasonal weather patterns, supply and demand factors,
transportation availability and price, and general economic conditions.

                                       50
<PAGE>

Worldwide political developments have historically also had an impact on oil
prices.  Periodically, Alliant Energy utilizes oil and gas swaps and forward
contracts to mitigate the impact of oil and gas price fluctuations.  Based on
Whiting's estimated gas and crude oil sales in 2000, and the swaps and forward
contracts in place at December 31, 1999, a 10% increase/decrease in gas and
crude oil prices for that period would impact Alliant Energy's pre-tax 2000
earnings by approximately $3.8 million.  A 10% increase/decrease in prices
during 1999 would have impacted Alliant Energy's 1999 pre-tax earnings by
approximately $3.0 million as relates to the commodity derivative instruments
outstanding during 1999.

Commodity Risk - Trading - Alliant Energy is exposed to market risks through
- --------------
its electricity commodity trading business, which is primarily conducted
through Alliant Energy's 50/50 joint venture with Cargill.  The joint
venture's trading activities principally consist of marketing and trading
over-the-counter forward contracts for the purchase and sale of electricity.
The majority of the forward contracts represent commitments to purchase or
sell electricity at fixed prices in the future and require settlement by
physical delivery of electricity or are netted out in accordance with industry
trading standards.  The market prices used to determine fair values reflect
the joint ventures' best estimate considering various factors, including
closing exchanges and over-the-counter quotations, time value and volatility
factors.  The joint venture manages the market risks inherent in its trading
activities through established trading and risk management policies and
tools.  The principal tool utilized is a one-day variance/covariance
value-at-risk model with assessment adjustments made based on weather,
transmission availability, generation outages and other factors.  The
estimated one-day market Value at Risk (VAR) for the joint venture as of
December 31, 1999 and 1998 was $0.3 million and $0.7 million, respectively,
which were calculated with a 99% confidence level.  The low, average and high
VAR in 1999 were $0.1 million, $0.3 million and $1.5 million, respectively.

Equity Price Risk - Alliant Energy maintains trust funds at IESU and WP&L to
- -----------------
fund its anticipated nuclear decommissioning costs.  As of December 31, 1999
and 1998, these funds were invested primarily in domestic equity and debt
instruments.  WP&L has entered into an equity collar that uses options to
mitigate the effect of significant market fluctuations on its common stock
investments.   Alliant Energy's exposure to fluctuations in equity prices or
interest rates will not affect its consolidated results of operations as such
fluctuations are recorded in equally offsetting amounts of investment income
and depreciation (WP&L) or interest (IESU) expense when they are realized.

At December 31, 1999 and 1998, Alliant Energy had an investment in the stock
of McLeod, a publicly traded telecommunications company, valued at $1,124
million and $320 million, respectively.  A 10% increase (decrease) in the
quoted market price at December 31 would have increased (decreased) the value
of the investment at December 31, 1999 and 1998 by approximately $112 million
and $32 million, respectively.  Refer to Note 10 of the "Notes to Consolidated
Financial Statements" for a discussion of how Alliant Energy accounts for its
investment in McLeod.

At December 31, 1999 and 1998, Alliant Energy had various investments,
accounted for under the cost method of accounting, in publicly traded utility
companies in New Zealand and Australia which were valued at $97 million and $3
million, respectively.  A 10% increase (decrease) in the quoted market prices
at December 31 would have increased (decreased) the value of the investment at
December 31, 1999 and 1998 by approximately $9.7 million and $0.3 million,
respectively.

Currency Risk - Alliant Energy has investments in various countries where the
- --------------
net investments are not hedged, including Australia, Brazil, China, New
Zealand, and Singapore.  As a result, these investments are subject to
currency exchange risk with fluctuations in currency exchange rates.  At
December 31, 1999 and 1998, Alliant Energy had a cumulative foreign currency
translation loss of  $9.6 million and $7.1 million, respectively, recorded in
"Accumulated other comprehensive income" on its Consolidated Balance Sheets
that primarily related to decreases in value of the New Zealand dollar in
relation to the U.S. Dollar.  Based on Alliant Energy's investments at
December 31, 1999 and 1998, a 10% sustained increase/decrease over the next
twelve months in the foreign exchange rates of Australia, Brazil, China, New
Zealand and Singapore would decrease/increase the cumulative foreign currency
translation loss by $17.2 million and $6.4 million, respectively.

Refer to Notes 1(n) and 11 of the "Notes to Consolidated Financial Statements"
for a further discussion of Alliant Energy's derivative financial instruments.

Accounting Pronouncements
In June 1998, the FASB issued SFAS 133.  The Statement establishes accounting
and reporting standards requiring that every derivative instrument be recorded
on the balance sheet as either an asset or liability measured at its fair
value.  The Statement requires that changes in the derivative's fair value be
recognized currently in earnings unless specific hedge accounting criteria are
met.  Special accounting for qualifying hedges allows a derivative's gains and
losses to offset related results on the hedged item in the income statement,
and requires that a company must formally document, designate, and assess the
effectiveness of transactions that receive hedge accounting.

SFAS 133 is effective for fiscal years beginning after June 15, 2000 and must
be applied to (a) derivative instruments and (b) certain derivative
instruments embedded in hybrid contracts that were issued, acquired or
substantively modified after December 31, 1998 (effective dates noted are as
amended by SFAS 137).  Alliant Energy has organized a cross-functional project
team to assist in implementing SFAS 133.  The team consists of both Alliant
Energy employees and a consultant that has been engaged to support the
project.  The team has begun to inventory financial instruments, commodity
contracts and other commitments with the purpose of identifying and assessing
all of Alliant Energy's derivatives.  Although the impact of implementing SFAS
133 has not yet been quantified, it could increase volatility in earnings and
other comprehensive income.  Alliant Energy is analyzing various alternatives
relating to the possible early adoption of SFAS 133 in 2000.  SFAS 133 may
only be adopted on the first day of any quarter prior to the required adoption
date.

Accounting for Obligations Associated with the Retirement of Long-Lived Assets
The staff of the SEC has questioned certain of the current accounting
practices of the electric utility industry, including IESU and WP&L, regarding
the recognition, measurement and classification of decommissioning costs for
nuclear generating stations in financial statements of electric utilities.  In
response to these questions, the FASB has a project on its agenda to review
the accounting for obligations associated with the retirement of long-lived
assets, including decommissioning of nuclear power plants.  If current
electric utility industry accounting practices for nuclear power plant
decommissioning are changed, the annual provision for decommissioning could
increase relative to 1999, and the estimated cost for decommissioning could be
recorded as a liability (rather than as accumulated depreciation), with
recognition of an increase in the cost of the related nuclear power plant.
Assuming no significant change in regulatory treatment, IESU and WP&L do not
believe that such changes, if required, would have an adverse effect on their
financial condition or results of operations due to their ability to recover
decommissioning costs through rates.

Inflation
Alliant Energy, IESU and WP&L do not expect the effects of inflation at
current levels to have a significant effect on their financial condition or
results of operations.

Environmental
The pollution abatement programs of IESU, WP&L, IPC and Resources are subject
to continuing review and are revised from time to time due to changes in
environmental regulations, changes in construction plans and escalation of
construction costs.  While management cannot precisely forecast the effect of
future environmental regulations on Alliant Energy's operations, it has taken
steps to anticipate the future while also meeting the requirements of current
environmental regulations.

The Clean Air Act Amendments of 1990 (Act) require emission reductions of SO2,
NOx and other air pollutants to achieve reductions of atmospheric chemicals
believed to cause acid rain.  IESU, WP&L and IPC have met the provisions of
Phase I of the Act and Phase II of the Act.  The Act also governs SO2
allowances, which are defined as an authorization for an owner to emit one ton
of SO2 into the atmosphere.  IESU, WP&L and IPC are reviewing their options to
ensure they will have sufficient allowances to offset their emissions in the
future and believe that the potential costs of complying with these provisions
of Title IV of the Act will not have a material adverse impact on their
financial condition or results of operations.

The Act and other federal laws also require the EPA to study and regulate, if
necessary, additional issues that potentially affect the electric utility
industry, including emissions relating to ozone transport, mercury and
particulate control as well as modifications to the PCB rules.  In July 1997,

                                       52
<PAGE>

the EPA issued final rules that would tighten the National Ambient Air Quality
Standards for ozone and particulate matter emissions and in June 1998, the EPA
modified the PCB rules.  Alliant Energy cannot predict the long-term
consequences of these rules on its financial condition or results of
operations.

In October 1998, the EPA issued a final rule requiring 22 states, including
Wisconsin, to modify their state implementation plans to address the ozone
transport issue.  However, on May 25, 1999, a federal appeals court delayed
indefinitely the implementation of the rule.  On March 3, 2000, the federal
appeals court affirmed EPA's NOx rule for the affected states.  However, the
court found that the EPA had failed to explain how Wisconsin contributes
significantly to non-attainment in any other state thus it has vacated the
rule as relates to Wisconsin.  Given the EPA could still appeal this decision,
and Alliant Energy is still reviewing the recent court order, Alliant Energy
is unable to predict the final outcome of this issue.  The implementation of
the rule would likely require WP&L to reduce its NOx emissions at all of its
plants to a fleet average of .15 lbs/mmbtu by 2003.  WP&L is following this
issue closely and continues to evaluate various options to meet the emission
levels.  Based on existing technology, the preliminary estimates indicate that
capital investments would be in the range of $150 million to $215 million.
Refer to the "Liquidity and Capital Resources - Rates and Regulatory Matters"
section for a discussion of a filing WP&L made with the PSCW regarding seeking
rate recovery of these costs.

Revisions to the Wisconsin Administrative Code have been proposed that could
have a significant impact on WP&L's operation of the Rock River Generating
Station in Beloit, Wisconsin.  The proposed revisions will affect the amount
of heat that the generating station can discharge into the Rock River.  WP&L
cannot presently predict the final outcome of the rule, but believes that, as
the rule is currently proposed, the capital investments and/or modifications
required to meet the proposed discharge limits could be significant.

On February 28, 1998, the EPA issued the final report to Congress on the Study
of Hazardous Air Pollutant Emissions from Electric Utility Steam Generating
Units regarding hazardous air pollutant emissions from electric utilities (the
HAPs report).  The HAPs report concluded that mercury emissions from
coal-fired generating plants were a concern.  However, the EPA does not
believe it has sufficient information regarding such emissions.  To remedy
this lack of information, the EPA required IESU, WP&L, IPC and all other
applicable electric utilities in the U.S. to start collecting information
regarding the types and amount of mercury emitted as of January 1, 1999.  To
better understand mercury emissions, the EPA required WP&L to conduct stack
tests at several of its generating stations.  Both stations selected have
completed their stack testing.  Although the control of mercury emissions from
generating plants is uncertain at this time, Alliant Energy believes that the
capital investments and/or modifications required to control mercury emissions
could be significant.

Pursuant to an internal review of operations in 1998, IPC discovered that Unit
No. 6 at its generating facility in Dubuque, Iowa required a Clean Air Act
Acid Rain permit and CEMS.  IPC has informed its environmental regulators and
has installed the CEMS and obtained the permit.  Pursuant to its internal
review, IPC also identified and disclosed to regulators a potentially similar
situation at its Lansing, Iowa generating facility.  In the second quarter of
1999, the EPA determined that Lansing units 1 and 2 are affected units.
Therefore, in the third quarter of 1999, IPC installed the CEMS at both of
these facilities and in December 1999 IPC submitted its certification to the
EPA for the Lansing facility.  IPC has received a settlement offer from the
EPA, dated December 3, 1999, to settle the matter for $550,000.  IPC has since
responded with a counter offer and negotiations continue.

On February 4, 1999, Whiting received a Notice of Violation letter from the
ADEQ, citing Whiting for flaring sour gas in excess of permit limits and not
having a valid permit.  In June 1999, the ADEQ sent Whiting a Consent
Administrative Order proposing a voluntary civil penalty of $225,000 for
Whiting's alleged emission violations.  The consent agreement was finalized on
November 9, 1999, resulting in a civil penalty of $99,000, Whiting performing
two mitigation projects, installing an air monitor to run for one full year
and submitting a Title V permit.

WP&L has been notified by the EPA that it is a PRP with respect to
environmental impacts identified at the MIG/DeWane Landfill Superfund Site.
WP&L is participating in the initiation of an alternate dispute resolution
process to allocate liability associated with the investigation and
remediation of the site.  Management believes that any likely action resulting
from this matter will not have a material adverse effect on WP&L's financial
condition or results of operations.

                                       53
<PAGE>

IPC has been notified by the EPA that it is a PRP with respect to
environmental impacts identified at the Missouri Electric Works, Inc. (MEW)
site in Cape Girardeau, Missouri.  IPC has been served with a complaint filed
by the MEW Site Trust Fund, the PRP group involved in investigating and
remediating the site, for response costs incurred by the PRP group.  IPC
believes that it is not liable as a PRP for this site because it did not
arrange for the disposal of any waste materials at the site.  IPC has filed an
answer to the complaint, discovery is ongoing and settlement discussions
continue.

WP&L has been notified by Monroe County, Wisconsin that it is a PRP with
respect to environmental impacts identified at the Monroe County Interim
Landfill in Sparta, Wisconsin.  WP&L has provided a summary of records and
documents relating to waste disposal at the landfill to Monroe County.  WP&L
cannot currently estimate what liability, if any, it may have with respect to
this site.

A global treaty has been negotiated that could require reductions of
greenhouse gas emissions from utility plants.  In November 1998, the U.S.
signed the treaty and agreed with the other countries to resolve all remaining
issues by the end of 2000.  At this time, management is unable to predict
whether the U.S. Congress will ratify the treaty.  Given the uncertainty of
the treaty ratification and the ultimate terms of the final regulations,
management cannot currently estimate the impact the implementation of the
treaty would have on Alliant Energy's operations.

The Low-Level Radioactive Waste Policy Amendments Act of 1985 mandates that
each state must take responsibility for the storage of low-level radioactive
waste produced within its borders.  The States of Iowa and Wisconsin are
members of the six-state Midwest Interstate Low-Level Radioactive Waste
Compact (Compact) which is responsible for development of any new disposal
capability within the Compact member states.  In June 1997, the Compact
commissioners voted to discontinue work on a proposed waste disposal facility
in the State of Ohio because the expected cost of such a facility was
comparably higher than other options currently available.  Dwindling waste
volumes and continued access to existing disposal facilities were also reasons
cited for the decision.  A disposal facility located near Barnwell, South
Carolina continues to accept the low-level waste and IESU and WP&L currently
ship the waste each produces to such site, thereby minimizing the amount of
low-level waste stored on-site.  Given technological advances, waste
compaction and the reduction in the amount of waste generated, DAEC and
Kewaunee each have on-site storage capability sufficient to store low-level
waste expected to be generated over at least the next ten years.  While
Alliant Energy is unable to predict how long the Barnwell facility will
continue to accept its waste, continuing access to this facility expands
Alliant Energy's on-site storage capability indefinitely.

See Notes 12(f) and 12(g) of the "Notes to Consolidated Financial Statements"
for a further discussion of Alliant Energy's environmental issues.

Power Supply
Wisconsin enacted electric reliability legislation in 1998 (Wisconsin
Reliability Act) with the goal of assuring reliable electric energy for
Wisconsin.  The law allows the construction of merchant power plants in the
state and streamlines the regulatory approval process for building new
generation and transmission facilities.  As a requirement of the legislation,
the PSCW completed a regional transmission constraint study.  The PSCW is
authorized to order construction of new transmission facilities, based on the
findings of its constraint study, through December 31, 2004.

On September 24, 1997, the PSCW ordered WP&L and two other Wisconsin utilities
to arrange for additional electric capacity to help maintain reliable service
for their customers.  In July 1998, Alliant Energy and SkyGen announced an
agreement whereby SkyGen would build, own and operate a power plant in
Wisconsin capable of producing up to 450 MW of electricity.  Under the
agreement, Alliant Energy will purchase the capacity to meet the electric
needs of its utility customers, as outlined by the Wisconsin Reliability Act.
A third party filed an appeal to the EPA Appeals Board on the issue of NOx
mitigation.  In the fourth quarter of 1999, the WDNR issued a revised air
permit which was appealed again by the third party.  In March 2000, the EPA
denied the third party's final appeal which finalizes the air permitting
process and allows for construction of the plant.

The EPA appeal process resulted in the SkyGen project being delayed until the
summer of 2001.  Alliant Energy has made other contractual commitments to

                                       54

ensure an 18% reserve margin in 2000, as required for Wisconsin.  Part of this
effort includes purchased power contracts at higher costs than the SkyGen
power, including purchasing power from 54 portable diesel generators that will
be located at various substation locations within WP&L's service territory.
These higher costs are included in a rate increase requested by WP&L in
December 1999 as discussed in "Liquidity and Capital Resources - Rates and
Regulatory Matters - WP&L."

IESU and IPC are currently exploring the possibility of transitioning from the
MAPP reliability region to MAIN so all of Alliant Energy will belong to the
same reliability region.  Alliant Energy is unable to predict the outcome of
this issue at this time.

Alliant Energy notes that it will take time for new transmission and power
plant projects to be approved and built in Wisconsin.  While Alliant Energy
currently expects to meet customer demands in 2000, unanticipated reliability
issues could still arise in the event Wisconsin experiences unexpected power
plant outages, transmission system outages or extended periods of extremely
hot weather.

                 REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


To the Shareowners of Alliant Energy Corporation:

We have audited the accompanying consolidated balance sheets and
statements of capitalization of Alliant Energy Corporation (a Wisconsin
Corporation) and subsidiaries as of December 31, 1999 and 1998, and the
related consolidated statements of income, cash flows and changes in
common equity for each of the three years in the period ended December
31, 1999.  These financial statements and the supplemental schedule
referred to below are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements
and supplemental schedule based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are
free of material misstatement.  An audit includes examining, on a test
basis, evidence supporting the amounts and disclosures in the financial
statements.  An audit also includes assessing the accounting principles
used and significant estimates made by management, as well as evaluating
the overall financial statement presentation. We believe that our audits
provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present
fairly, in all material respects, the financial position of Alliant
Energy Corporation and subsidiaries as of December 31, 1999 and 1998, and
the results of their operations and their cash flows for each of the
three years in the period ended December 31,1999, in conformity with
generally accepted accounting principles.

Our audit was made for the purpose of forming an opinion on the basic
financial statements taken as a whole.  The schedule listed in Item
14(a)(2) is presented for purposes of complying with the Securities and
Exchange Commission's rules and is not part of the basic financial
statements.  This schedule has been subjected to the auditing procedures
applied in the audit of the basic financial statements and, in our
opinion, fairly states in all material respects the financial data
required to be set forth therein in relation to the basic financial
statements taken as a whole.

                           ALLIANT ENERGY CORPORATION
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
(a)  General - The Consolidated Financial Statements include the accounts of
Alliant Energy and its consolidated subsidiaries.  Alliant Energy is an
investor-owned holding company, incorporated in Wisconsin, whose primary
subsidiaries are IESU, WP&L, IPC, Resources and Corporate Services.  IESU,
WP&L and IPC are engaged principally in the generation, transmission,
distribution and sale of electric energy; the purchase, distribution,
transportation and sale of natural gas; and water and steam services in
selective markets.  The principal markets of IESU, WP&L and IPC are located in
Iowa, Wisconsin, Minnesota and Illinois.  Resources (through its numerous
direct and indirect subsidiaries) provides energy products and services to
domestic and international markets; provides industrial services including
environmental, engineering and transportation services; invests in affordable
housing initiatives; and invests in various other strategic initiatives.
Corporate Services is the subsidiary formed to provide administrative services
to Alliant Energy and its subsidiaries as required under PUHCA.

The consolidated financial statements reflect investments in controlled
subsidiaries on a consolidated basis.  All significant intercompany balances
and transactions, other than certain energy-related transactions affecting
IESU, WP&L and IPC, have been eliminated from the Consolidated Financial
Statements.  Such energy-related transactions are made at prices that
approximate market value and the associated costs are recoverable from
customers through the rate making process.  The financial statements are
prepared in conformity with generally accepted accounting principles, which
give recognition to the rate making and accounting practices of FERC and state
commissions having regulatory jurisdiction.  Certain prior period amounts have
been reclassified on a basis consistent with the current year presentation.

Unconsolidated investments for which Alliant Energy has at least a 20% voting
interest are generally accounted for under the equity method of accounting.
These investments are stated at acquisition cost, increased or decreased for
Alliant Energy's equity in net income or loss, which is included in
"Miscellaneous, net" in the Consolidated Statements of Income and decreased for
any dividends received.  Investments that do not meet the criteria for
consolidation or the equity method of accounting are accounted for under the
cost method.

The preparation of the financial statements requires management to make
estimates and assumptions that affect: a) the reported amounts of assets and
liabilities and the disclosure of contingent assets and liabilities at the
date of the financial statements; and b) the reported amounts of revenues and
expenses during the reporting period.  Actual results could differ from those
estimates.

(b)  Regulation - Alliant Energy is a registered public utility holding
company subject to regulation by the SEC under PUHCA.  IESU, WP&L and IPC are
subject to regulation by the FERC and their respective state regulatory
commissions (IUB, PSCW, MPUC and ICC).

(c)  Regulatory Assets - IESU, WP&L and IPC are subject to the provisions of
SFAS 71, "Accounting for the Effects of Certain Types of Regulation."  SFAS 71
provides that rate-regulated public utilities record certain costs and credits
allowed in the rate making process in different periods than for unregulated
entities.  These are deferred as regulatory assets or regulatory liabilities
and are recognized in the Consolidated Statements of Income at the time they
are reflected in rates.  At December 31, 1999 and 1998, regulatory assets of
$297.0 million and $315.3 million, respectively, were comprised of the
following items (in millions):

Refer to the individual notes referenced above for a further discussion of
certain items reflected in regulatory assets.  If a portion of IESU's, WP&L's
or IPC's operations become no longer subject to the provisions of SFAS 71 as a
result of competitive restructuring or otherwise, a write-down of related
regulatory assets would be required, unless some form of transition cost
recovery is established by the appropriate regulatory body that would meet the
requirements under generally accepted accounting principles for continued
accounting as regulatory assets during such recovery period.  In addition,
IESU, WP&L or IPC would be required to determine any impairment to other
assets and write-down such assets to their fair value.

(d)  Income Taxes - Alliant Energy follows the liability method of accounting
for deferred income taxes, which requires the establishment of deferred tax
assets and liabilities, as appropriate, for all temporary differences between
the tax basis of assets and liabilities and the amounts reported in the
financial statements.  Deferred taxes are recorded using currently enacted tax
rates.

Except as noted below, income tax expense includes provisions for deferred
taxes to reflect the tax effects of temporary differences between the time
when certain costs are recorded in the accounts and when they are deducted for
tax return purposes.  As temporary differences reverse, the related
accumulated deferred income taxes are reversed to income.  Investment tax
credits have been deferred and are subsequently credited to income over the
average lives of the related property.  As part of the affordable housing and
oil and gas production businesses, Alliant Energy is eligible to claim certain
tax credits.  These tax credits reduce current federal taxes to the extent
Alliant Energy has consolidated taxes payable.

Consistent with Iowa rate making practices for IESU and IPC, deferred tax
expense is not recorded for certain temporary differences (primarily related
to utility property, plant and equipment).  As the deferred taxes become
payable (over periods exceeding 30 years for some generating plant
differences) they are recovered through rates.  Accordingly, IESU and IPC have
recorded deferred tax liabilities and regulatory assets for certain temporary
differences, as identified in Note 1(c).  In Wisconsin, the PSCW has allowed
rate recovery of deferred taxes on all temporary differences since August
1991.  WP&L established a regulatory asset associated with those temporary
differences occurring prior to August 1991 that will be recovered in future
rates.

Alliant Energy files a consolidated federal income tax return.  Under the
terms of an agreement between Alliant Energy and its subsidiaries, the
subsidiaries calculate their respective federal income tax provisions and make
payments to or receive payments from Alliant Energy as if they were separate
taxable entities.

(e)  Common Shares Outstanding - Weighted average common shares outstanding
used to calculate basic and diluted earnings per share for 1999, 1998 and 1997
were as follows:

<TABLE>

</TABLE>

In 1999, 1,275,355 options to purchase shares of common stock, with an average
exercise price of $30.55, were excluded from the calculation of diluted
earnings per share as the exercise prices were greater than the average market
price.

(f)  Temporary Cash Investments - Temporary cash investments are stated at
cost, which approximates market value, and are considered cash equivalents for
the Consolidated Statements of Cash Flows.  These investments consist of
short-term liquid investments that have maturities of less than 90 days from
the date of acquisition.

(g)  Depreciation of Utility Property, Plant and Equipment - IESU, WP&L and
IPC use a combination of remaining life and straight-line depreciation methods
as approved by their respective regulatory commissions.  The remaining life of
DAEC, of which IESU is a co-owner, is based on the NRC license end-of-life of
2014.  The remaining life of Kewaunee, of which WP&L is a co-owner, is based
on the PSCW approved revised end-of-life of 2002 (prior to May 1997 the
calculation was based on the NRC license end-of-life of 2013).  Depreciation

<PAGE>

expense related to the decommissioning of DAEC and Kewaunee is discussed in
Note 12(h).  The average rates of depreciation for electric and gas properties
of IESU, WP&L and IPC, consistent with current rate making practices, were as
follows:

</TABLE>

(h)  Property, Plant and Equipment - Utility plant (other than acquisition
adjustments) is recorded at original cost, which includes overhead and
administrative costs and AFUDC.  At December 31, 1999, IESU had $25.6 million
of acquisition adjustments, net of accumulated amortization, included in
utility plant ($6 million of such balance is currently being recovered in
IESU's rates).  AFUDC, which represents the cost during the construction period
of funds used for construction purposes, is capitalized as a component of the
cost of utility plant.  The amount of AFUDC applicable to debt funds and to
other (equity) funds, a non-cash item, is computed in accordance with the
prescribed FERC formula.  These capitalized costs are recovered in rates as
the cost of the utility plant is depreciated.  The aggregate gross rates used
were as follows:

                1999           1998          1997
             ------------   ------------  ------------
IESU            7.9%           8.9%          6.7%
WP&L            5.4%           5.2%          6.2%
IPC             5.3%           7.0%          6.0%

Other property, plant and equipment is recorded at original cost.  Upon
retirement or sale of other property and equipment, the cost and related
accumulated depreciation are removed from the accounts and any gain or loss is
included in "Miscellaneous, net" in the Consolidated Statements of Income.
Normal repairs, maintenance and minor items of utility plant and other
property, plant and equipment are expensed.  Ordinary retirements of utility
plant, including removal costs less salvage value, are charged to accumulated
depreciation upon removal from utility plant accounts and no gain or loss is
recognized.

(i)  Operating Revenues - Alliant Energy accrues revenues for services
rendered but unbilled at month-end in order to more properly match revenues
with expenses.  In the third quarter of 1999, Alliant Energy recorded a $9
million increase in the estimate of utility services rendered but unbilled at
month-end.  This change was a result of the implementation of a refined
estimation process compared with the unbilled revenues recorded at June 30,
1999 using the estimation process in effect at that time.  In accordance with
an order from the PSCW, effective January 1, 1998, off-system gas sales for
WP&L are included in the Consolidated Statements of Income as a reduction of
the cost of gas sold rather than as gas revenues.  Off-system gas sales at
WP&L were $12.8 million, $11.5 million and $11.1 million in 1999, 1998 and
1997, respectively.

(j)  Utility Fuel Cost Recovery - IESU's and IPC's tariffs provide for
subsequent adjustments to its electric and natural gas rates for changes in
the cost of fuel and purchased energy and in the cost of natural gas purchased
for resale.  Changes in the under/over collection of these costs are reflected
in "Electric and steam production fuels" and "Cost of utility gas sold" in the
Consolidated Statements of Income.  The cumulative effects are reflected on
the Consolidated Balance Sheets as a current asset or current liability,
pending automatic reflection in future billings to customers.  At IESU and
IPC, purchased capacity costs are not recovered from electric customers
through energy adjustment clauses.  Recovery of these costs must be addressed
in base rates in a formal rate proceeding.

WP&L's retail electric rates are based in part on forecasted fuel and
purchased-power costs.  Under PSCW rules, Wisconsin utilities can seek
emergency rate increases if the annual costs are more than 3% higher than the
estimated costs used to establish rates.  WP&L has a gas performance incentive
which includes a sharing mechanism whereby 40% of all gains and losses
relative to current commodity prices, as well as other benchmarks, are
retained by WP&L rather than refunded to or recovered from customers.

                                       68
<PAGE>

(k)  Nuclear Refueling Outage Costs - The IUB allows IESU to collect, as part
of its base revenues, funds to offset other operation and maintenance
expenditures incurred during refueling outages at DAEC.  As these revenues are
collected, an equivalent amount is charged to other operation and maintenance
expenses with a corresponding credit to a reserve.  During a refueling outage,
the reserve is reversed to offset the refueling outage expenditures.
Operating expenses incurred during refueling outages at Kewaunee are expensed
by WP&L as incurred.

(l)  Nuclear Fuel - Nuclear fuel for DAEC is leased.  Annual nuclear fuel
lease expenses include the cost of fuel, based on the quantity of heat
produced for the generation of electric energy, plus the lessor's interest
costs related to fuel in the reactor and administrative expenses.  Nuclear
fuel for Kewaunee is recorded at its original cost and is amortized to expense
based upon the quantity of heat produced for the generation of electricity.
This accumulated amortization assumes spent nuclear fuel will have no residual
value.  Estimated future disposal costs of such fuel are expensed based on
kilowatt-hours generated.

(m)  Translation of Foreign Currency - Assets and liabilities of international
investments, where the local currency is the functional currency, have been
translated at year-end exchange rates and related income statement results
have been translated using average exchange rates prevailing during the year.
Adjustments resulting from translation have been recorded in other
comprehensive income.

(n) Derivative Financial Instruments - From time to time, Alliant Energy uses
derivative financial instruments to hedge exposures to fluctuations in
interest rates, certain commodity prices and volatility in a portion of
natural gas sales volumes due to weather.  These instruments are used to
mitigate risks and are not to be used for speculative purposes.  Under the
deferral method of accounting, gains and losses related to derivatives that
qualify as hedges are recognized in earnings when the underlying hedged item
or physical transaction is recognized in income.

Alliant Energy is exposed to losses related to financial instruments in the
event of counterparties' nonperformance.  Alliant Energy has established
controls to determine and monitor the creditworthiness of counterparties in
order to mitigate its exposure to counterparty credit risk.  Alliant Energy is
not aware of any counterparties that will fail to meet their obligations.

Refer to Note 11 for a further discussion of Alliant Energy's derivative
financial instruments.

(2)  MERGER
On April 21, 1998, IES, WPLH and IPC completed a merger forming Alliant
Energy.  The merger was accounted for as a pooling of interests and the
accompanying Consolidated Financial Statements, along with the related notes,
are presented as if the companies were combined as of the earliest period
presented.

In association with the merger, Alliant Energy eliminated 167 positions in
1998.  As a result, Alliant Energy recorded $15 million of expenses during
1998 in "Other operation" expense related to the employee separation benefits
to be paid to the impacted employees.  The bulk of the positions eliminated
were administrative in nature and resulted from no longer needing certain
duplicative positions given the consolidation of the three companies.  The
departure dates for the impacted employees varied based on the need for their
services during the transition period as well as certain other factors.  The
balance of the accrual at December 31, 1999 and 1998 was $1.0 million and $5.7
million, respectively.  As of December 31, 1999, all of the terminated
employees had actually left the organization.  As of December 31, 1998, 156 of
the terminated employees had actually left the organization.  The balance
remaining in the accrued liability at December 31, 1999 related to payments to
certain terminated executives that were being paid out over a 18-36 month
period pursuant to the terms of their respective severance agreements.  The
only significant adjustments made to the liability after the initial accrual
were to reflect the actual payments of the employee separation benefits.

In association with the merger, Alliant Energy entered into a three-year
consulting agreement, which expires in the second quarter of 2001, with Wayne
Stoppelmoor, the Chief Executive Officer of IPC prior to the consummation of
the merger.  Under the terms of the consulting agreement, Mr. Stoppelmoor, who
also serves as Vice Chairman of Alliant Energy's Board of Directors, receives
annual fees of $324,500, $324,500 and $200,000 for his services during the
respective periods of the agreement.

(3)  LEASES
IESU has a capital lease covering its 70% undivided interest in nuclear fuel
purchased for DAEC.  Future purchases of fuel may also be added to the fuel
lease.  This lease provides for annual one-year extensions and IESU intends to
continue exercising such extensions.  Interest costs under the lease are based
on commercial paper costs incurred by the lessor.  IESU is responsible for the
payment of taxes, maintenance, operating cost, risk of loss and insurance
relating to the leased fuel.  The lessor has a $45 million credit agreement
with a bank supporting the nuclear fuel lease.  The agreement continues on a
year-to-year basis, unless either party provides at least a three-year notice
of termination; no such notice of termination has been provided by either
party.  Annual nuclear fuel lease expenses (included in "Electric and steam
production fuels" in the Consolidated Statements of Income) for 1999, 1998 and
1997 were $12.7 million, $14.2 million and $16.6 million, respectively.

Alliant Energy's operating lease rental expenses for 1999, 1998 and 1997 were
$24.6 million, $21.6 million and  $20.3 million, respectively.  Alliant
Energy's future minimum lease payments by year are as follows (in millions):

(4)  UTILITY ACCOUNTS RECEIVABLE
Utility customer accounts receivable, including unbilled revenues, arise
primarily from the sale of electricity and natural gas.  At December 31, 1999,
Alliant Energy was serving a diversified base of residential, commercial and
industrial customers and did not have any significant concentrations of credit
risk.

Similar accounts receivable financing arrangements exist for two of Alliant
Energy's utility subsidiaries, IESU and WP&L.  In both cases, the utility
subsidiaries sell up to a pre-determined maximum amount of accounts receivable
to a financial institution on a limited recourse basis.  Accounts receivable
sold include receivables arising from sales to customers and to other public,
municipal and cooperative utilities, as well as from billings to the co-owners
of the jointly-owned electric generating plants operated by utility
subsidiaries of Alliant Energy.  The amounts are discounted at the
then-prevailing market rate and additional administrative fees are payable
according to the activity levels undertaken.  All billing and collection
functions remain the responsibility of the respective utilities.  Specifics of
the two agreements include (dollars in millions):

Refer to the "Non-regulated Businesses" column of Note 14 for summary income
statement data of Resources.  Alliant Energy has not presented separate
financial statements for Resources because it is a wholly-owned subsidiary of
Alliant Energy and because management has determined that such information is
not material to holders of senior notes of Resources.  Alliant Energy has
fully and unconditionally guaranteed the payment of principal and interest on
the senior notes.

(6)  INCOME TAXES

Deferred tax liabilities are not recognized for temporary differences related
to investments in foreign subsidiaries and in unconsolidated foreign
affiliates that are essentially permanent in duration.  As of December 31,
1999, Alliant Energy had not recorded a U.S. tax provision of approximately
$1.4 million relating to approximately $4.1 million of unremitted earnings
from two of its investments in China as these earnings are expected to be
reinvested permanently overseas in China.

(7)  BENEFIT PLANS
(a)  Pension Plans and Other Postretirement Benefits - Alliant Energy has
several non-contributory defined benefit pension plans that cover
substantially all of its employees who are subject to a collective bargaining
agreement.  Plan benefits are generally based on years of service and
compensation during the employees' latter years of employment.  Eligible
employees of Alliant Energy that are not subject to a collective bargaining
agreement are covered by the Alliant Energy Cash Balance Pension Plan, a
non-contributory defined benefit pension plan.  During each year of service,
Alliant Energy credits each participant's account with a benefit credit equal
to 5% of base pay as well as a guaranteed minimum interest credit equal to
4%.  The projected unit credit actuarial cost method was used to compute
pension cost and the accumulated and projected benefit obligations.  Alliant
Energy's policy is to fund all of the pension plans at an amount that is at
least equal to the minimum funding requirements mandated by the Employee
Retirement Income Security Act of 1974, as amended, and that does not exceed
the maximum tax deductible amount for the year.

Alliant Energy also provides certain other postretirement benefits to
retirees, including medical benefits for retirees and their spouses (and
Medicare Part B reimbursement for certain retirees) and, in some cases,
retiree life insurance.  IESU's and IPC's funding policy for other
postretirement benefits is generally to fund an amount up to the cost
calculated using SFAS 106, "Employers' Accounting for Postretirement Benefits
Other Than Pensions," while WP&L's funding policy is generally to fund tax
deductible amounts up to the incurred but unclaimed paid medical claim reserve
and tax deductible amounts (if any) to the retiree medical account within the
Cash Balance Pension Plan.

The weighted-average assumptions as of the measurement date of September 30
are as follows:

During 1998 and 1997, Alliant Energy recognized an additional $10.3 million
and $5.1 million, respectively, of costs in accordance with SFAS 88.  The
charges were for severance and early retirement programs in the respective
years.  In addition, during 1999, 1998 and 1997, Alliant Energy recognized
$0.5 million, $10.2 million and $1.7 million, respectively, of curtailment
charges relating to Alliant Energy's other postretirement benefits.

The benefit obligation and fair value of plan assets for the postretirement
welfare plans with benefit obligations in excess of plan assets were $121.3
million and $58.7 million, respectively, as of September 30, 1999 and $146.5
million and $45.3 million, respectively, as of September 30, 1998.  The
projected benefit obligation, accumulated benefit obligation and fair value of
plan assets for the pension plans with benefit obligations in excess of plan
assets were $231.4 million, $225.9 million and $219.8 million, respectively,
as of September 30, 1999 and $250.5 million, $241.1 million and $217.9
million, respectively, as of September 30, 1998.

Alliant Energy also sponsors several non-qualified pension plans which cover
certain current and former officers.  At December 31, 1999 and 1998, the
funded balances of such plans totaled approximately $5 million.  Alliant
Energy's pension benefit obligation under these plans was $28.0 million and
$25.8 million at December 31, 1999 and 1998, respectively.  Alliant Energy's
pension expense under these plans was $2.5 million, $4.5 million, and $3.7
million in 1999, 1998 and 1997, respectively.

A significant number of Alliant Energy employees also participate in defined
contribution pension plans (401(k) plans).  Alliant Energy's contributions to
the plans, which are based on the participants' level of contribution, were
$7.4 million, $7.7 million, and $5.5 million in 1999, 1998 and 1997,
respectively.

(b)  Long-Term Equity Incentive Plan - Alliant Energy has a long-term equity
incentive plan which permits the grant of non-qualified stock options,
incentive stock options, restricted stock, performance shares and performance
units to key employees.  As of December 31, 1999, non-qualified stock options,
restricted stock, performance shares and performance units had been granted to
key employees.  The maximum number of shares of Alliant Energy common stock
that may be issued under the plan may not exceed 3.8 million (no awards may be
granted on or after January 22, 2004).

Options are granted at the fair market value of the shares on the date of
grant.  The options vest over three years and expire no later than 10 years
after the grant date with the exception of participants that retire.  Their
options become fully vested upon retirement and remain exercisable at any time
prior to their expiration date, or for three years after the effective date of
the retirement, whichever period is shorter.  Participants' options that are
not vested become forfeited when the participant leaves Alliant Energy and
their vested options expire after three months.  A summary of the stock option
activity for 1999, 1998 and 1997 is as follows:

Alliant Energy follows APB 25, "Accounting for Stock Issued to Employees," to
account for stock options.  No compensation cost is recognized because the
option exercise price is equal to the market price of the underlying stock on
the date of grant.  Had compensation cost for the plan been determined based
on the Black-Scholes value at the grant dates for awards as prescribed by SFAS
123 "Accounting for Stock-Based Compensation," pro forma net income and
earnings per share would have been:

                                                   1999       1998       1997

Pro forma net income (in millions)                $192.7      $93.5     $144.3
Pro forma earnings per share (basic and diluted)    $2.46      $1.22      $1.89


In 1999, 65,752 shares of restricted stock were awarded, all of which were
outstanding at December 31, 1999, and are restricted for a three-year period.
Any unvested shares of restricted stock become fully vested upon retirement.
Participants' restricted stock becomes forfeited when the participant leaves
Alliant Energy.  Alliant Energy follows APB 25 to account for restricted
stock.  Compensation cost, which is recognized over the three-year restriction
period, was $0.4 million in 1999.  Prior to the merger, various restricted
stock awards were granted under the former IES Long-Term Incentive Plan.  For
most of the awards, restrictions lapsed effective with the merger.
Compensation cost of $0.4 million, $1.3 million and $0.4 million was
recognized in 1999, 1998 and 1997, respectively.

The payout to key employees of Corporate Services for performance units/shares
is contingent upon achievement of specified levels of total return to
shareowners of Alliant Energy compared with an investor-owned utility peer
group over a three-year period (the payout is contingent upon achievement of
specified earnings growth for key employees of Resources).  Performance
units/shares are paid out in cash or shares of Alliant Energy's common stock
and are modified by a performance multiplier, which ranges from 0 to 2.00
based on the three-year average performance criteria.  Performance shares have
an intrinsic value equal to the market price of a share on the date of grant
and performance units represent accumulated dividends on the shares underlying
the non-qualified stock options based on the annual dividend rate at the grant
date.  Pursuant to APB 25, Alliant Energy accrues the expenses for these plans
over the three-year period the services are performed.  Alliant Energy
recognized $1.6 million, $0.2 million and $0.4 million of expense for these
plans in 1999, 1998 and 1997, respectively.

(8)  COMMON, PREFERRED AND PREFERENCE STOCK
(a)  Common Stock - During 1999, 1998 and 1997, Alliant Energy issued
1,353,971 shares; 890,035 shares and 687,962 shares of common stock under its
various stock plans, respectively.  In addition, 260,039 shares were issued in
1998 in connection with the acquisition of oil and gas properties.  At
December 31, 1999, Alliant Energy had a total of 7.0 million shares available
for issuance pursuant to its Shareowner Direct Plan, Long-Term Equity
Incentive Plan and 401(k) Savings Plan.  Alliant Energy has declared a
quarterly dividend of 50 cents per share each quarter since the consummation
of the merger.

During 1998 and 1997, Alliant Energy reacquired 1,133 shares and 3,278 shares,
respectively, of its common stock on the open market.  The shares were
reacquired by IES prior to the consummation of the merger and were
subsequently issued to various Alliant Energy directors and employees.  At
December 31, 1999, no shares remained held as treasury stock.

Alliant Energy has a Shareowner Rights Plan whereby rights will be exercisable
only if a person or group acquires, or announces a tender offer to acquire,
15% or more of Alliant Energy's common stock.  Each right will initially
entitle shareowners to buy one-half of one share of Alliant Energy's common
stock.  The rights will only be exercisable in multiples of two at an initial
price of $95.00 per full share, subject to adjustment.  If any shareowner
acquires 15% or more of the outstanding common stock of Alliant Energy, each
right (subject to limitations) will entitle its holder to purchase, at the
right's then current exercise price, a number of common shares of Alliant
Energy or of the acquirer having a market value at the time of twice the
right's per full share exercise price.  The Board of Directors is also
authorized to reduce the 15% thresholds to not less than 10%.

                                       75

Alliant Energy's utility subsidiaries each have common stock dividend
restrictions based on their respective bond indentures and articles of
incorporation.  Each utility has restrictions on the payment of common stock
dividends that are commonly found with preferred stock.  In addition, at IESU
and IPC their ability to pay common stock dividends is restricted based on
requirements associated with sinking funds.  WP&L's common stock dividends are
restricted to the extent that such dividend would reduce the common stock
equity ratio to less than 25%.  Also at WP&L, in rate order UR-110, the PSCW
ordered that it must approve the payment of dividends by WP&L to Alliant
Energy that are in excess of the level forecasted in the rate order ($58.3
million), if such dividends would reduce WP&L's average common equity ratio
below 52.00% of total capitalization.  The dividends paid by WP&L to Alliant
Energy since the rate order was issued have not exceeded the level forecasted
in the rate order.

All non-employee directors are eligible to receive a 25% matching contribution
in Alliant Energy common stock for limited cash purchases, up to $10,000, of
Alliant Energy's common stock through Alliant Energy's Shareowner Direct
Plan.  Matching contributions of $2,500 each were made to nine directors in
1999.

(b)  Preferred and Preference Stock - In 1993, IPC issued 545,000 shares of
6.40%, $50 par value preferred stock with a final redemption date of May 1,
2022.  Under the provisions of the mandatory sinking fund, beginning in 2003,
IPC is required to redeem annually $1.4 million of 6.40% preferred stock
(27,250 shares).

The carrying value of Alliant Energy's cumulative preferred stock at December
31, 1999 and 1998 was $114 million and $113 million, respectively.  The fair
market value, based upon the market yield of similar securities and quoted
market prices, at December 31, 1999 and 1998 was $97 million and $109 million,
respectively.

(9)  DEBT
(a)  Short-Term Debt - Alliant Energy maintains committed bank lines of
credit, most of which are at the bank prime rates, to obtain short-term
borrowing flexibility, including pledging lines of credit as security for any
commercial paper outstanding.  Amounts available under these committed lines
of credit totaled $250 million as of December 31, 1999.  Commitment fees are
paid to maintain these lines and there are no conditions which restrict the
unused lines of credit.  Resources also maintains a revolving credit agreement
with various banking institutions.  The unborrowed portion of this agreement
is also used to support Resources' commercial paper program.  The amount
available under this agreement as of December 31, 1999, was $150 million.

Resources is also party to a revolving 3-Year Credit Agreement with various
banking institutions.  The agreement extends through October 2000, with
one-year extensions available upon agreement by the parties.  Unused borrowing
availability under this agreement is also used to support Resources'
commercial paper program.  A combined maximum of $450 million of borrowings
under this agreement and the commercial paper program may be outstanding at
any one time.  Interest rates and maturities are set at the time of
borrowing.  The rates are based upon quoted market prices and the maturities
are less than one year.  At December 31, 1999, Resources had $139 million of
commercial paper outstanding and backed by its 3-Year Credit Agreement with
discount rates ranging from 5.90%-6.32%.  Resources intends to continue
issuing commercial paper backed by this facility and no conditions existed at
December 31, 1999 that would prevent the issuance of commercial paper or
direct borrowings on its bank lines.  As a result, Alliant Energy had been
classifying this debt as long-term.  However, since this agreement expires in
October 2000, beginning in October 1999 this debt (including commercial paper
backed by this facility) is now being classified as short-term.

(b)  Long-Term Debt - IESU's Indentures and Deeds of Trust securing its First
Mortgage Bonds constitute direct first mortgage liens upon substantially all
tangible public utility property.  IESU's Indenture and Deed of Trust securing
its Collateral Trust Bonds constitutes a second lien on substantially all
tangible public utility property while First Mortgage Bonds remain
outstanding.  Substantially all of WP&L's and IPC's utility plant is secured
by their First Mortgage Bonds.  WP&L also maintains an unsecured indenture
relating to the issuance of debt securities.  In addition, Alliant Energy's
long-term debt includes unsecured debentures, notes payable and revenue bonds
related to its affordable housing properties.

Debt maturities (excluding periodic sinking fund requirements, which will not
require additional cash expenditures) for 2000 to 2004 are $54.8 million,
$84.4 million, $2.4 million, $7.5 million and $89.8 million, respectively.
Depending upon market conditions, it is currently anticipated that a majority
of the maturing debt will be refinanced with the issuance of long-term
securities.

The carrying value of Alliant Energy's long-term debt at December 31, 1999 and
1998 was $1,597 million and $1,664 million, respectively.  The fair market
value, based upon the market yield of similar securities and quoted market
prices, at December 31, 1999 and 1998 was $1,561 million and $1,753 million,
respectively.

</TABLE>

The fair market value of the New Zealand/Australia investments is generally
based on quoted market prices.  The difference in the carrying value and fair
value relates to investments that are not marked to market under SFAS 115,
"Accounting for Certain Investments in Debt and Equity Securities."  The
carrying amount of Alliant Energy's current assets and current liabilities
approximates fair value because of the short maturity of such financial
instruments. Since IESU, WP&L and IPC are subject to regulation, any gains or
losses related to the difference between the carrying amount and the fair
value of its financial instruments may not be realized by Alliant Energy's
shareowners.

Nuclear Decommissioning Trust Funds - As required by SFAS 115, IESU's and
WP&L's debt and equity security investments in the nuclear decommissioning
trust funds are classified as available for sale.  The fair market value of
the nuclear decommissioning trust funds is as reported by the trustee,
adjusted for the tax effect of unrealized gains and losses.  Net unrealized
holding gains were recorded as part of accumulated provision for
depreciation.  The funds realized gains from the sales of securities of $6.6
million, $1.2 million and $0.2 million in 1999, 1998 and 1997, respectively
(cost of the investments based on specific identification were $111.7 million,
$71.9 million and $68.6 million, respectively).

Investment in McLeod - Alliant Energy held 19.1 million and 20.6 million of
shares of common stock (including 2.6 million unexercised vested options) in
McLeod, a telecommunications company, at December 31, 1999 and 1998,
respectively.  The cost basis of the investment, net of the cost to exercise
the options, was $28 million and $29 million at December 31, 1999 and 1998,
respectively.  McLeod declared a 2-for-1 stock split which was effective in
July 1999 (the December 1998 shares have been adjusted for the split).
Pursuant to the provisions of SFAS 115, Alliant Energy's investment in McLeod
is considered an available-for-sale security thus the carrying value of the
investment is adjusted to the estimated fair value each quarter based on the
closing price at the end of the quarter.  The adjustments do not impact
earnings as the unrealized gains or losses, net of taxes, are recorded
directly to the common equity section of the Consolidated Balance Sheets and
are a component of "Accumulated other comprehensive income."  In addition, any
such gains or losses are reflected in current earnings only at the time they
are realized through a sale.  Alliant Energy sold approximately 7% (1.4
million shares, as adjusted for the stock split) of its investment in McLeod
in 1999, resulting in pre-tax gains of $40.3 million (proceeds of $40.9
million less a cost basis of $0.6 million as computed under the
first-in-first-out (FIFO) method).

Alliant Energy entered into an agreement in November 1998, as amended, with
McLeod whereby Alliant Energy's ability to sell the McLeod stock is subject to
various restrictions.  The agreement provides that until December 31, 2001,
Alliant Energy and its affiliates generally may not sell or otherwise dispose
of shares of McLeod stock beneficially owned by Alliant Energy and its
affiliates, other than to a subsidiary of Alliant Energy, without the prior
written consent of the Board of Directors of McLeod.  However, the amended
agreement provides that the Board of Directors of McLeod may permit Alliant
Energy and its affiliates to sell a specified number of shares of McLeod stock
per quarter during specified time periods.  In addition, if Alliant Energy and
its affiliates are not provided the opportunity to sell, on an annual basis,
an aggregate number of shares of McLeod stock equal to 15% of the shares of
McLeod stock owned by Alliant Energy and its affiliates as of December 31,
1998, then Alliant Energy may terminate the amended November 1998 agreement.

Investments in Foreign Entities - Alliant Energy has investments in foreign
entities on its Consolidated Balance Sheets that included investments in
several New Zealand and Australian utility entities, investments in several
generation facilities in China and an investment in secured debentures of a
development project in Mexico.  The New Zealand and Australian investments are
accounted for under the cost method and the China investments are accounted
for under the equity method.  The geographic concentration of these
investments at December 31 was as follows (in millions):

instruments.

(11)  DERIVATIVE FINANCIAL INSTRUMENTS
Information relating to derivative financial instruments utilized by Alliant
Energy is as follows:

(a) Interest Rate Swaps and Forward Contracts - In November 1999, Resources
terminated its two interest rate swap agreements, each with notional amounts

                                       78
<PAGE>

of $100 million of debt.  The agreements converted variable rate debt into
fixed rate debt and Resources received an insignificant settlement payment
upon termination which was recorded as an offset to interest expense.  On
November 1, 1999, Resources entered into an interest rate forward contract
with a notional amount of $250 million related to the anticipated issuance of
$250 million of senior notes.  The senior notes were priced on November 4,
1999, and the forward contract was settled, which resulted in a cash payment
of $2.5 million by Resources.  Because the fair value of the change in the
forward contract was highly correlated to the fair value of the change in the
senior notes, the $2.5 million is being deferred as an adjustment to the
carrying value of the notes and amortized into interest expense over the life
of the senior notes, which mature in 2009.

At December 31, 1999, WP&L had two interest rate swap agreements outstanding
(both expiring in January 2000), with an aggregate notional amount of $30
million.  The agreements converted variable rate debt into fixed rate debt.
If WP&L had terminated the agreements at December 31, 1999, WP&L would have
made an insignificant payment.  Settlements on these swaps occurring during
the year were recorded as a component of interest expense.

(b) Utility Gas Commodities Instruments - WP&L uses gas commodity swaps to
reduce the impact of price fluctuations on gas purchased and injected into
storage during the summer months and withdrawn and sold at current market
prices during the winter months.  The notional amount of gas commodity swaps
outstanding as of December 31, 1999 and 1998 was 1.9 million and 5.8 million
dekatherms, respectively.  Unrealized gains/losses are deferred and accounted
for as hedges of the fair value of the gas in storage as the indexed price
WP&L pays is highly correlated to the market price that WP&L will receive from
customers under the current rate making structure.  If WP&L had terminated all
of the agreements existing at December 31, 1999 and 1998, WP&L would have
realized an estimated gain of $0.1 million and $0.8 million, respectively,
based on current NYMEX gas futures contracts adjusted for the proper basis
differential.  Settlements of these swaps are recorded as an adjustment to the
cost of gas sold in the period that coincides with the withdrawal and sale of
the hedged gas in storage.

(c) Oil and Gas Commodities Instruments - Whiting is exposed to commodity
price risk in the pricing of its oil and gas production.  Alliant Energy
entered into swap transactions in the third quarter of 1999 to hedge the
ultimate sales price for approximately two-thirds of Whiting's anticipated gas
production from November 1, 1999 through December 31, 2000.  At December 31,
1999, the notional amount of these swaps was 13.4 million dekatherms and the
estimated fair value was approximately $1.9 million.  The fair value was
determined based on the difference between the fixed price of the swaps and
NYMEX futures prices, adjusted for the necessary basis differential.  In
December 1999, Alliant Energy entered into a crude oil swap to fix Whiting's
ultimate sales price for 650 barrels per day from December 1, 1999 to December
31, 2000.  At December 31, 1999, the estimated fair value of these swaps was
approximately ($0.3) million, as determined by the difference between the
fixed prices of the swaps and NYMEX futures prices for the appropriate
delivery locations.  Alliant Energy also used commodity derivative instruments
to hedge a portion of the anticipated sales of Whiting's gas production during
1999.  The notional amounts of these derivative instruments was 11,530,000
dekatherms, none of which were outstanding at December 31, 1999.  The net
settlements of such instruments resulted in Alliant Energy recognizing a
pre-tax loss of $5.2 million in 1999.  All of Whiting's gas and crude oil
swaps are treated as hedges of the anticipated sales of Whiting's production
as the notional amounts and fixed prices of these swaps are highly correlated
to Whiting's volumes of production and the ultimate sales prices of such
production.  Settlements related to all of Whiting's swaps are recognized as
income in the periods in which the swap is settled, which coincides with the
sale of the hedged oil and gas production.

(d) Weather Derivatives - WP&L uses weather derivatives to reduce the impact
of weather volatility on its natural gas sales volumes.  In September 1998,
WP&L entered into a non-exchange traded "weather collar" with a contract
period commencing on November 1, 1998 and ending on March 31, 1999.  The
maximum amount to be paid or received under the collar was $5,000,000.  WP&L
recognized a gain in "Miscellaneous, net" on this collar of $2.5 million in
the first quarter of 1999 upon termination of the collar.  In August 1999,
WP&L entered into a non-exchange traded "weather collar" with a contract
period commencing on November 1, 1999 and ending on March 31, 2000.  The
maximum payment amount is $5,000,000.  Pursuant to the requirements of
EITF-99-2, WP&L is accounting for this instrument using the intrinsic value
method and recognized an unrealized gain in "Miscellaneous, net" of $2.4
million in the fourth quarter of 1999.

                                       79
<PAGE>

(e) Nuclear Decommissioning Trust Fund Investments - WP&L entered into an
equity collar that uses written options to mitigate the effect of significant
market fluctuations on its common stock investments in its nuclear
decommissioning trust funds.  The program is designed to protect the
portfolio's value while allowing the funds to earn a total return modestly in
excess of long-term expectations over the two-year hedge period, which expires
September 2000.  The notional amount of the options was $78 million and $52
million at December 31, 1999 and 1998, respectively.  The options are reported
at fair market value each reporting period.  These fair value changes do not
impact net income as they are recorded as equally offsetting changes in the
investment in nuclear decommissioning trust funds and accumulated
depreciation.  The option liability fair value exceeded the premium received
by $17.8 million and $8.9 million at December 31, 1999 and December 31, 1998,
respectively, as reported by the trustee.

(12)  COMMITMENTS AND CONTINGENCIES
(a)   Construction and Acquisition Program - Plans for Alliant Energy's
construction and acquisition program can be found elsewhere in this report in
the "Liquidity and Capital Resources - Capital Requirements" section of MD&A.

(b)  Purchased-Power, Coal and Natural Gas Contracts - Alliant Energy has
entered into purchased-power capacity and coal contracts and its minimum
commitments are as follows (dollars in millions, MWHs and tons in thousands):

                                       Coal
           Purchased-Power          (including
                                  transportation)

          Dollars     MWHs     Dollars       Tons
          --------  ---------  ---------  -----------
2000       $108.2    1,571       $63.2      16,227
2001         69.6      925        44.5      11,434
2002         47.0      280        19.6       5,991
2003         36.5      280        14.2       4,993
2004         25.2      219        11.7       3,878

Alliant Energy is in the process of negotiating several new coal contracts.
In addition, it expects to supplement its coal contracts with spot market
purchases to fulfill its future fossil fuel needs.  Alliant Energy also has
various natural gas supply, transportation and storage contracts outstanding.
The minimum dekatherm commitments, in millions, for 2000-2004 are 185.6,
150.8, 133.2, 110.3 and 9.8, respectively.  The minimum dollar commitments for
2000-2004, in millions, are $94.0, $70.3, $47.7, $40.0 and $3.2,
respectively.  The gas supply commitments are all index-based.  Alliant Energy
expects to supplement its natural gas supply with spot market purchases as
needed.

(c)  Information Technology Services - Alliant Energy has an agreement,
expiring in 2004, with EDS for information technology services.  Alliant
Energy's anticipated operating and capital expenditures under the agreement for
2000 are estimated to total approximately $16 million.  Future costs under the
agreement are variable and are dependent upon Alliant Energy's level of usage
of technological services from EDS.

(d)  Financial Guarantees and Commitments - Alliant Energy has financial
guarantees, which were generally issued to support third-party borrowing
arrangements and similar transactions, amounting to $17 million and $18
million outstanding at December 31, 1999 and 1998, respectively.  Such
guarantees are not reflected in the consolidated financial statements.
Management believes that the likelihood of Alliant Energy having to make any
material cash payments under these agreements is remote.

In addition, as part of Alliant Energy's electricity trading joint venture
with Cargill, both Alliant Energy and Cargill have made guarantees to certain
counterparties regarding the performance of contracts entered into by the
joint venture.  Revocable guarantees of approximately $95 million and $50
million have been issued, of which approximately $20 million and $5 million
were outstanding at December 31, 1999 and 1998, respectively.  Under the terms
of the joint venture agreement, any payments required under the guarantees
would be shared by Alliant Energy and Cargill on a 50/50 basis to the extent
the joint venture is not able to reimburse the guarantor for payments made
under the guarantee.

                                       80
<PAGE>

As of December 31, 1999 and 1998, Resources had extended commitments to
provide $6.1 million and $19 million, respectively, in nonrecourse, permanent
financing to developers which were secured by affordable housing properties.
Alliant Energy anticipates other lenders will ultimately finance these
properties.

(e)  Nuclear Insurance Programs - Public liability for nuclear accidents is
governed by the Price Anderson Act of 1988, which sets a statutory limit of
$9.5 billion for liability to the public for a single nuclear power plant
incident and requires nuclear power plant operators to provide financial
protection for this amount.  As required, IESU provides this financial
protection for a nuclear incident at DAEC through a combination of liability
insurance ($200 million) and industry-wide retrospective payment plans ($9.3
billion).  Under the industry-wide plan, each operating licensed nuclear
reactor in the U.S. is subject to an assessment in the event of a nuclear
incident at any nuclear plant in the U.S.  The owners of DAEC could be
assessed a maximum of $88.1 million per nuclear incident, with a maximum of
$10 million per incident per year (of which IESU's 70% ownership portion would
be approximately $61.7 million and $7 million, respectively) if losses
relating to the incident exceeded $200 million.  These limits are subject to
adjustments for changes in the number of participants and inflation in future
years.  On a similar note, WP&L, as a 41% owner of Kewaunee, is subject to an
overall assessment of approximately $36.1 million per incident, not to exceed
$4.1 million payable in any given year.

IESU and WP&L are members of NEIL, which provides $1.9 billion of insurance
coverage for IESU and $1.8 billion for WP&L on certain property losses for
property damage, decontamination and premature decommissioning.  The proceeds
from such insurance, however, must first be used for reactor stabilization and
site decontamination before they can be used for plant repair and premature
decommissioning.  NEIL also provides separate coverage for additional expense
incurred during certain outages.  Owners of nuclear generating stations
insured through NEIL are subject to retroactive premium adjustments if losses
exceed accumulated reserve funds.  NEIL's accumulated reserve funds are
currently sufficient to more than cover its exposure in the event of a single
incident under the primary and excess property damage or additional expense
coverages.  However, IESU could be assessed annually a maximum of $1.9 million
for NEIL primary property, $2.8 million for NEIL excess property and $0.5
million for NEIL additional expenses if losses exceed the accumulated reserve
funds.  WP&L could be assessed annually a maximum of $1.1 million for NEIL
primary property, $1.6 million for NEIL excess property and $0.4 million for
NEIL additional expense coverage.  IESU and WP&L are not aware of any losses
that they believe are likely to result in an assessment.

In the unlikely event of a catastrophic loss at Kewaunee or DAEC, the amount
of insurance available may not be adequate to cover property damage,
decontamination and premature decommissioning.  Uninsured losses, to the
extent not recovered through rates, would be borne by Alliant Energy and could
have a material adverse effect on Alliant Energy's financial condition and
results of operations.

(f)  Environmental Liabilities - Alliant Energy had recorded the following
environmental liabilities, and regulatory assets associated with certain of
these liabilities, as of December 31 (in millions):

Alliant Energy's significant environmental liabilities are discussed further
below.

                                       81
<PAGE>

Manufactured Gas Plant Sites - IESU, WP&L and IPC have current or previous
- ----------------------------
ownership interests in 34, 14 and 9 sites, respectively, previously associated
with the production of gas for which they may be liable for investigation,
remediation and monitoring costs relating to the sites.  The companies are
working pursuant to the requirements of various federal and state agencies to
investigate, mitigate, prevent and remediate, where necessary, the
environmental impacts to property, including natural resources, at and around
the sites in order to protect public health and the environment.  The
companies each believe that they have completed the remediation at various
sites, although they are still in the process of obtaining final approval from
the applicable environmental agencies for some of these sites.

Each company records environmental liabilities based upon periodic studies,
most recently updated in the third quarter of 1999, related to the MGP sites.
Such amounts are based on the best current estimate of the remaining amount to
be incurred for investigation, remediation and monitoring costs for those
sites where the investigation process has been or is substantially completed,
and the minimum of the estimated cost range for those sites where the
investigation is in its earlier stages.  It is possible that future cost
estimates will be greater than current estimates as the investigation process
proceeds and as additional facts become known.  The amounts recognized as
liabilities are reduced for expenditures made and are adjusted as further
information develops or circumstances change.  Costs of future expenditures
for environmental remediation obligations are not discounted to their fair
value.

Management currently estimates the range of remaining costs to be incurred for
the investigation, remediation and monitoring of all Alliant Energy sites to
be approximately $33 million to $61 million.  IESU, WP&L and IPC currently
estimate their share of the remaining costs to be incurred to be approximately
$16 million to $33 million, $6 million to $8 million, and $11 million to $20
million, respectively.

Under the current rate making treatment approved by the PSCW, the MGP
expenditures of WP&L, net of any insurance proceeds, are deferred and
collected from gas customers over a five-year period after new rates are
implemented.  The MPUC also allows the deferral of MGP-related costs
applicable to the Minnesota sites and IPC has been successful in obtaining
approval to recover such costs in rates in Minnesota.  The IUB has permitted
utilities to recover prudently incurred costs.  As a result, regulatory assets
have been recorded by each company which reflect the probable future rate
recovery, where applicable.  Considering the current rate treatment, and
assuming no material change therein, IESU, WP&L and IPC believe that the
clean-up costs incurred for these MGP sites will not have a material adverse
effect on their respective financial conditions or results of operations.

Settlement has been reached with all of IESU's and WP&L's insurance carriers
regarding reimbursement for its MGP-related costs and all issues have been
resolved.  IPC has settled with all but one of its insurance carriers.  The
following insurance recoveries were available as of December 31 (in millions):

               1999      1998
             ---------  --------
IESU           $18.5      $18.5
IPC              5.3        4.8
WP&L             2.1        2.1
             ---------  --------
               $25.9      $25.4
             =========  ========

Pursuant to their applicable rate making treatment, IESU and IPC have recorded
their recoveries in "Other long-term liabilities and deferred credits" and
WP&L has recorded its recoveries as an offset against its regulatory assets.

National Energy Policy Act of 1992 - NEPA requires owners of nuclear power
- -----------------------------------
plants to pay a special assessment into a "Uranium Enrichment Decontamination
and Decommissioning Fund."  The assessment is based upon prior nuclear fuel
purchases.  IESU is recovering the costs associated with this assessment
through its electric fuel adjustment clauses over the period the costs are
assessed.  Alliant Energy continues to pursue relief from this assessment
through litigation.

Oil and Gas Properties Dismantlement and Abandonment Costs - Whiting is
- ----------------------------------------------------------
responsible for certain dismantlement and abandonment costs related to various

                                       82
<PAGE>

off-shore oil and gas platforms (and related on-shore plants and equipment),
the most significant of which is located off the coast of California.  Whiting
estimates the total costs for these properties to be approximately $13 million
and the most significant expenditures are not expected to be incurred until
2004.  In accordance with applicable accounting requirements, Whiting has
accrued these costs.

(g)  Spent Nuclear Fuel - Nuclear Waste Policy Act of 1982 assigned
responsibility to the DOE to establish a facility for the ultimate disposition
of high level waste and spent nuclear fuel and authorized the DOE to enter
into contracts with parties for the disposal of such material beginning in
January 1998.  IESU and WP&L entered into such contracts and have made the
agreed payments to the Nuclear Waste Fund held by the U.S. Treasury.  The
companies were subsequently notified by the DOE that it was not able to begin
acceptance of spent nuclear fuel by the January 31, 1998 deadline.
Furthermore, the DOE has experienced significant delays in its efforts and
material acceptance is now expected to occur no earlier than 2010 with the
possibility of further delay being likely.  Alliant Energy has participated in
several litigation proceedings against the DOE on this issue and the
respective courts have affirmed the DOE's responsibility for spent nuclear
fuel acceptance.  Alliant Energy is evaluating its options for recovery of
damages due to the DOE's delay in accepting spent nuclear fuel.

The Nuclear Waste Policy Act of 1982 assigns responsibility for interim
storage of spent nuclear fuel to generators of such spent nuclear fuel, such
as IESU and WP&L.  In accordance with this responsibility, IESU and WP&L have
been storing spent nuclear fuel on site at DAEC and Kewaunee, respectively,
since plant operations began.  IESU will have to increase its spent fuel
storage capacity at DAEC to store all of the spent fuel that will be produced
before the current license expires in 2014.  To provide assurance that both
the operating and post-shutdown storage needs are satisfied, construction of a
dry cask storage facility is being planned.  With minor modifications planned
for 2001, Kewaunee would have sufficient fuel storage capacity to store all of
the fuel it will generate through the end of the NRC license life in 2013.  No
decisions have been made concerning post-shutdown storage needs.  Legislation
is being considered on the federal level that would, among other provisions,
expand the DOE's permanent spent nuclear fuel storage to include interim
storage for spent nuclear fuel as early as 2003.  This legislation has been
passed in the U.S. Senate and submitted in the U.S. House.  The prospects for
the legislation being approved by the U.S. Senate and the President, and
subsequent successful implementation by the DOE, are uncertain at this time.

(h)  Decommissioning of DAEC and Kewaunee - Pursuant to the most recent
electric rate case order, the IUB and PSCW allow IESU and WP&L to recover $6
million and $16 million annually for their share of the cost to decommission
DAEC and Kewaunee, respectively.  Decommissioning expense is included in
"Depreciation and amortization" in the Consolidated Statements of Income and
the cumulative amount is included in "Accumulated depreciation" on the
Consolidated Balance Sheets to the extent recovered through rates.

<PAGE>

The rate recovery figures for DAEC only included an inflation estimate through
1997.  Both IESU and WP&L are funding all rate recoveries for decommissioning
into external trust funds and funding on a tax-qualified basis to the extent
possible.  All of the rate recovery assumptions are subject to change in
future regulatory proceedings.  In accordance with their respective regulatory
requirements, IESU and WP&L record the earnings on the external trust funds as
interest income with a corresponding entry to interest expense at IESU and to
depreciation expense at WP&L.  The earnings accumulate in the external trust
fund balances and in accumulated depreciation on utility plant.

IESU's 70% share of the estimated cost to decommission DAEC based on the most
recent site-specific study completed in 1998 is $334.2 million, in 1998
dollars.  This study includes the costs to terminate DAEC's NRC license and to
return the site to a greenfield condition.  IESU's 70% share of the estimated
cost to decommission DAEC based on the most recent NRC minimum formula, using
the direct disposal method, is $351.2 million in 1998 dollars.  The NRC
minimum formula is intended to apply only to the cost of terminating DAEC's
NRC license.  The additional decommissioning expense funding requirements
which should result from these updated studies are not reflected in IESU's
rates.

(i)  Legal Proceedings - Alliant Energy is involved in legal and
administrative proceedings before various courts and agencies with respect to
matters arising in the ordinary course of business.  Although unable to
predict the outcome of these matters, Alliant Energy believes that appropriate
reserves have been established and final disposition of these actions will not
have a material adverse effect on its financial condition or results of
operations.

(13)  JOINTLY-OWNED ELECTRIC UTILITY PLANT
Under joint ownership agreements with other Iowa and Wisconsin utilities,
IESU, WP&L and IPC have undivided ownership interests in jointly-owned
electric generating stations and related transmission facilities.  Each of the
respective owners is responsible for the financing of its portion of the
construction costs.  Kilowatt-hour generation and operating expenses are
divided on the same basis as ownership with each owner reflecting its
respective costs in its Consolidated Statements of Income.  Information
relative to IESU's, WP&L's and IPC's ownership interest in these facilities at
December 31, 1999 is as follows (dollars in millions):

(14)  SEGMENTS OF BUSINESS
Alliant Energy's principal business segments are:

o  Regulated domestic utilities - consists of Alliant Energy's three
   regulated utility operating companies (IESU, WP&L and IPC) serving
   customers in Iowa, Wisconsin, Minnesota and Illinois.  The regulated
   domestic utility business is broken down into three segments which are: a)
   electric operations; b) gas operations; and c) other, which includes the
   water and steam businesses and the unallocated portions of the utility
   business.
o  Non-regulated businesses - represents the operations of Resources and
   its subsidiaries.  This includes domestic and international energy products
   and services businesses; industrial services, which includes environmental,
   engineering and transportation services; investments in affordable housing
   initiatives; and investments in various other strategic initiatives.
o  Other - includes the operations of Alliant Energy's parent company and
   Corporate Services, as well as any reconciling/eliminating entries.

Intersegment revenues were not material to Alliant Energy's operations and
there was no single customer whose revenues exceeded 10% or more of Alliant
Energy's consolidated revenues.  Refer to Note 10 for a breakdown of Alliant
Energy's international investments by country.

In January 2000, Resources acquired a non-controlling interest in four
Brazilian electric utilities serving more than 820,000 customers for a total
investment of approximately $347 million.

exchangeable senior notes in the original aggregate principal amount of $402.5
million, due in 2030, with a closing date of February 1, 2000.  The
exchangeable senior notes have an interest rate of 7.25% through February 15,

guarantee the payment of principal and interest on the exchangeable senior
notes.

              REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Shareowners of IES Utilities Inc.:

We have audited the accompanying consolidated balance sheets and
statements of capitalization of IES Utilities Inc. (an Iowa
corporation) and subsidiaries as of December 31, 1999 and 1998, and
the related consolidated statements of income, retained earnings
and cash flows for each of the three years in the period ended
December 31, 1999.  These financial statements and the supplemental
schedule referred to below are the responsibility of the Company's
management.  Our responsibility is to express an opinion on these
financial statements and supplemental schedule based on our audits.

We conducted our audits in accordance with generally accepted
auditing standards.  Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement.  An audit
includes examining, on a test basis, evidence supporting the
amounts and disclosures in the financial statements.  An audit also
includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall
financial statement presentation.  We believe that our audits
provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present
fairly, in all material respects, the financial position of IES
Utilities Inc. and subsidiaries as of December 31, 1999 and 1998,
and the results of their operations and their cash flows for each
of the three years in the period ended December 31, 1999, in
conformity with generally accepted accounting principles.

Our audit was made for the purpose of forming an opinion on the basic
financial statements taken as a whole.  The schedule listed in Item
14(a)(2) is presented for purposes of complying with the Securities and
Exchange Commission's rules and is not part of the basic financial
statements.  This schedule has been subjected to the auditing procedures
applied in the audit of the basic financial statements and, in our
opinion, fairly states in all material respects the financial data
required to be set forth therein in relation to the basic financial
statements taken as a whole.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Except as modified below, the Alliant Energy Notes to Consolidated Financial
Statements are incorporated by reference insofar as they relate to IESU.

(1)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
(a)  General - The Consolidated Financial Statements include the accounts of
IESU and its consolidated subsidiaries.  In the fourth quarter of 1999,
IESU's subsidiaries were merged into IESU.  IESU is a subsidiary of Alliant
Energy and is engaged principally in the generation, transmission,
distribution and sale of electric energy; the purchase, distribution,
transportation and sale of natural gas; and steam services.  All of IESU's
retail customers are located in Iowa.

(i)  Operating Revenues - IESU accrues revenues for services rendered but
unbilled at month-end in order to more properly match revenues with
expenses.  In the third quarter of 1999, IESU recorded a $5 million increase
in the estimate of utility services rendered but unbilled at month-end.  This
change was a result of the implementation of a refined estimation process
compared with the unbilled revenues recorded at June 30, 1999 using the
estimation process in effect at that time.

(3)  LEASES
IESU's operating lease rental expenses for 1999, 1998 and 1997 were $8.9
million, $9.0 million and $8.3 million, respectively.  IESU's future minimum
lease payments by year are as follows (in millions):

(7)  BENEFIT PLANS
(a)  Pension Plans and Other Postretirement Benefits - IESU has a
non-contributory defined benefit pension plan that covers substantially all
of its employees who are subject to a collective bargaining agreement.  Plan
benefits are generally based on years of service and compensation during the
employees' latter years of employment.  Effective in 1998, eligible employees
of IESU that are not subject to a collective bargaining agreement are covered
by the Alliant Energy Cash Balance Pension Plan, a non-contributory defined
benefit pension plan.  The projected unit credit actuarial cost method was
used to compute pension cost and the accumulated and projected benefit
obligations.  IESU's policy is to fund the pension plan at an amount that is
at least equal to the minimum funding requirements mandated by ERISA and that
does not exceed the maximum tax deductible amount for the year.

IESU also provides certain other postretirement benefits to retirees,
including medical benefits for retirees and their spouses and, in some cases,
retiree life insurance.  IESU's funding policy for other postretirement
benefits is generally to fund an amount up to the cost calculated using SFAS
106, "Employers' Accounting for Postretirement Benefits Other Than
Pensions."

The weighted-average assumptions as of the measurement date of September 30
are as follows:

</TABLE>

During 1997, IESU recognized an additional $3.8 million of costs in
accordance with SFAS 88 for severance and early retirement programs.  In
addition, during 1998, IESU recognized $1.2 million of curtailment charges
relating to IESU's other postretirement benefits.

The pension benefit cost shown above (and in the following tables) for 1999
and 1998 represents only the pension benefit cost for bargaining unit
employees of IESU covered under the bargaining unit pension plan that is
sponsored by IESU.  The pension benefit cost for IESU's non-bargaining
employees who are now participants in other Alliant Energy plans was $0.9
million and $2.7 million for 1999 and 1998, respectively, including a special
charge of $1.9 million in 1998 for severance and early retirement window
programs.  In addition, Corporate Services provides services to IESU.  The
allocated pension benefit costs associated with these services was $1.2
million and $0.5 million for 1999 and 1998, respectively.  The other
postretirement benefit cost shown above for each period (and in the following
tables) represents the other postretirement benefit cost for all IESU
employees.  The allocated other postretirement benefit cost associated with
Corporate Services for IESU was $0.4 million and $0.2 million for 1999 and
1998, respectively.

The assumed medical trend rates are critical assumptions in determining the
service and interest cost and accumulated postretirement benefit obligation
related to postretirement benefit costs.  A one percent change in the medical
trend rates for 1999, holding all other assumptions constant, would have the
following effects (in millions):

Alliant Energy sponsors several non-qualified pension plans which cover
certain current and former officers.  The pension expense allocated to IESU
for these plans was $0.8 million, $1.4 million and $2.3 million in 1999, 1998
and 1997, respectively.

IESU employees also participate in defined contribution pension plans (401(k)
plans) covering substantially all employees.  IESU's contributions to the
plans, which are based on the participants' level of contribution, were $2.0
million, $2.8 million and $1.2 million in 1999, 1998 and 1997, respectively.

(b)  Long-Term Debt - Debt maturities (excluding periodic sinking fund
requirements, which will not require additional cash expenditures) for 2000
to 2004 are $51.2 million, $81.5 million, $0.6 million, $4.1 million and $0,
respectively.  Depending upon market conditions, it is currently anticipated
that a majority of the maturing debt will be refinanced with the issuance of
long-term securities.

The carrying value of IESU's long-term debt at December 31, 1999 and 1998 was
$602 million and $652 million, respectively.  The fair market value, based
upon the market yield of similar securities and quoted market prices, at
December 31, 1999 and 1998 was $573 million and $687 million, respectively.

</TABLE>

The carrying amount of IESU's current assets and current liabilities
approximates fair value because of the short maturity of such financial
instruments.  The nuclear decommissioning trust funds realized gains from the
sales of securities of $2.5 million, $0.4 million and $0.1 million in 1999,
1998 and 1997, respectively (cost of the investments based on specific
identification were $25.5 million, $14.3 million and $14.6 million,
respectively).  Since IESU is subject to regulation, any gains or losses
related to the difference between the carrying amount and the fair value of
its financial instruments may not be realized by IESU's parent.

(12)  COMMITMENTS AND CONTINGENCIES
(b)  Purchased-Power, Coal and Natural Gas Contracts - Corporate Services has
entered into purchased-power capacity contracts as agent for IESU, WP&L and
IPC.  Based on the System Coordination and Operating Agreement, Alliant
Energy annually allocates purchased-power contracts to the individual
utilities.  Such process considers factors such as resource mix, load growth
and resource availability and as a result of that process, IESU was not
allocated any of the purchased-power contracts for 2000 to 2004.  IESU has
entered into a contract for the purchase of $9.3 million of capacity in 2000
from IPC.  See Note 17 for additional information.  In addition, Corporate
Services has entered into various coal contracts as agent for IESU, WP&L and
IPC.  Contract quantities are allocated to specific plants at the individual
utilities based on various factors including projected heat input
requirements, combustion compatibility and efficiency.  However, in 2000 and
2001, system-wide contracts of $24.6 million (6.5 million tons) and $12.5
million (3.6 million tons), respectively, have not yet been allocated to the
individual utilities due to the need for additional analysis of combustion
compatibility and efficiency.  The minimum commitments directly assigned to
IESU are as follows (dollars in millions, tons in thousands):

                      Coal
                   (including
                transportation)
             -----------------------

             ----------  -----------
2000           $12.8        2,300
2001            10.4        1,556
2002             3.7          619
2003             3.3          520
2004             3.2          475

Corporate Services is in the process of negotiating several new coal
contracts.  In addition, it expects to supplement its coal contracts with
spot market purchases to fulfill its future fossil fuel needs.  IESU also has
various natural gas supply, transportation and storage contracts
outstanding.  The minimum dekatherm commitments, in millions, for 2000-2004
are 93.8, 79.3, 72.1, 60.8 and 2.4, respectively.  The minimum dollar
commitments for 2000-2004, in millions, are $51.4, $39.0, $27.4, $23.5 and
$1.3, respectively.  The gas supply commitments are all index-based.  IESU
expects to supplement its natural gas supply with spot market purchases as
needed.

(c)  Information Technology Services - Alliant Energy has an agreement,
expiring in 2004, with EDS for information technology services.  IESU's
anticipated operating and capital expenditures under the agreement for 2000
are estimated to total approximately $13 million.  Future costs under the
agreement are variable and are dependent upon IESU's level of usage of
technological services from EDS.

(d)  Financial Guarantees and Commitments - IESU has financial guarantees,
which were generally issued to support third-party borrowing arrangements and
similar transactions, amounting to $17 million and $18 million outstanding at
December 31, 1999 and 1998, respectively.  Such guarantees are not reflected
in the consolidated financial statements.  Management believes that the
likelihood of IESU having to make any material cash payments under these
agreements is remote.

(14)  SEGMENTS OF BUSINESS
IESU is a regulated domestic utility, serving customers in Iowa, with three
principal business segments: a) electric operations; b) gas operations; and
c) other, which includes steam operations and the unallocated portions of the
utility business.  Intersegment revenues were not material to IESU's
operations and there was no single customer whose revenues exceeded 10% or
more of IESU's consolidated revenues.

*  Earnings  in 1998  were  impacted  by the  recording  of  approximately  $2
million,  $10  million,  $3 million  and $2 million of pre-tax  merger-related
expenses in the first, second, third and fourth quarters, respectively.

(17)  RELATED PARTY ISSUES
In association with the merger, IESU, WP&L and IPC entered into a System
Coordination and Operating Agreement which became effective with the merger.
The agreement, which has been approved by FERC, provides a contractual basis
for coordinated planning, construction, operation and maintenance of the
interconnected electric generation and transmission systems of the three
utility companies.  In addition, the agreement allows the interconnected
system to be operated as a single entity with off-system capacity sales and
purchases made to market excess system capability or to meet system
capability deficiencies.  Such sales and purchases are allocated among the
three utility companies based on procedures included in the agreement.  The
sales amounts allocated to IESU were $18.1 million and $18.0 million for 1999
and 1998, respectively.  The purchases allocated to IESU were $71.3 million
and $56.0 million for 1999 and 1998, respectively.  The procedures were
approved by both FERC and all state regulatory bodies having jurisdiction
over these sales.  Under the agreement, IESU, WP&L and IPC are fully
reimbursed for any generation expense incurred to support the sale to an
affiliate or to a non-affiliate.  Any margins on sales to non-affiliates are
distributed to the three utilities in proportion to each utility's share of
electric production at the time of sale.

Pursuant to a service agreement approved by the SEC under PUHCA, IESU
receives various administrative and general services from an affiliate,
Corporate Services.  These services are billed to IESU at cost based on
payroll and other expenses incurred by Corporate Services for the benefit of
IESU.  These costs totaled $93.9 million and $59.3 million for 1999 and 1998,
respectively, and consisted primarily of employee compensation, benefits and
fees associated with various professional services.  Corporate Services began
operations in May 1998 upon the consummation of the merger.

At December 31, 1999 and 1998, IESU had an intercompany payable to Corporate
Services of $16.4 million and $20.9 million, respectively.

              REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Shareowners of Wisconsin Power and Light Company:

We have audited the accompanying consolidated balance sheets and
statements of capitalization of Wisconsin Power and Light Company
(a Wisconsin corporation) and subsidiaries as of December 31, 1999
and 1998, and the related consolidated statements of income,
retained earnings and cash flows for each of the three years in the
period ended December 31, 1999.  These financial statements and the
supplemental schedule referred to below are the responsibility of
the Company's management.  Our responsibility is to express an
opinion on these financial statements and supplemental schedule
based on our audits.

We conducted our audits in accordance with generally accepted
auditing standards.  Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement.  An audit
includes examining, on a test basis, evidence supporting the
amounts and disclosures in the financial statements.  An audit also
includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall
financial statement presentation.  We believe that our audits
provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present
fairly, in all material respects, the financial position of
Wisconsin Power and Light Company and subsidiaries as of December
31, 1999 and 1998, and the results of their operations and their
cash flows for each of the three years in the period ended December
31, 1999, in conformity with generally accepted accounting
principles.

Our audit was made for the purpose of forming an opinion on the basic
financial statements taken as a whole.  The schedule listed in Item
14(a)(2) is presented for purposes of complying with the Securities and
Exchange Commission's rules and is not part of the basic financial
statements.  This schedule has been subjected to the auditing procedures
applied in the audit of the basic financial statements and, in our
opinion, fairly states in all material respects the financial data
required to be set forth therein in relation to the basic financial
statements taken as a whole.

(7)  BENEFIT PLANS
(a)  Pension Plans and Other Postretirement Benefits - WP&L has a
non-contributory, defined benefit pension plan that covers substantially all
of its employees who are subject to a collective bargaining agreement.  Plan
benefits are generally based on years of service and levels of compensation.
Effective in 1998, eligible employees of WP&L that are not subject to a
collective bargaining agreement are covered by the Alliant Energy Cash
Balance Pension Plan, a non-contributory defined benefit pension plan.  The
projected unit credit actuarial cost method was used to compute pension cost
and the accumulated and projected benefit obligations.  WP&L's policy is to
fund the pension plan at an amount that is at least equal to the minimum
funding requirements mandated by ERISA, and that does not exceed the maximum
tax deductible amount for the year.

WP&L also provides certain other postretirement benefits to retirees,
including medical benefits for retirees and their spouses and, in some cases,
retiree life insurance.  WP&L's funding policy is generally to fund tax
deductible amounts up to the incurred but unclaimed paid medical claim
reserve and tax deductible amounts (if any) to the retiree medical account
within the Cash Balance Pension Plan.

The weighted-average assumptions as of the measurement date of September 30
are as follows:

</TABLE>

During 1998 and 1997, WP&L recognized an additional $0.6 million and $1.3
million, respectively, of costs in accordance with SFAS 88.  The charges were
for severance and early retirement programs in the respective years.  In
addition, during 1998 and 1997, WP&L recognized $3.6 million and $1.7
million, respectively, of curtailment charges relating to WP&L's other
postretirement benefits.

The pension benefit cost shown above (and in the following tables) for 1999
and 1998 represents only the pension benefit cost for bargaining unit
employees of WP&L covered under the bargaining unit pension plan that is
sponsored by WP&L.  The pension benefit cost for WP&L's non-bargaining
employees who are now participants in other Alliant Energy plans was ($1.8)
million and $3.0 million for 1999 and 1998, respectively, including a special
charge of $3.6 million in 1998 for severance and early retirement window
programs.  In addition, Corporate Services provides services to WP&L.  The
allocated pension benefit costs associated with these services was $1.2
million and $0.6 million for 1999 and 1998, respectively.  The other
postretirement benefit cost shown above for each period (and in the following
tables) represents the other postretirement benefit cost for all WP&L
employees.  The allocated other postretirement benefit cost associated with
Corporate Services for WP&L was $0.4 million and $0.2 million for 1999 and
1998, respectively.

The assumed medical trend rates are critical assumptions in determining the
service and interest cost and accumulated postretirement benefit obligation
related to postretirement benefit costs.  A one percent change in the medical
trend rates for 1999, holding all other assumptions constant, would have the
following effects (in millions):

and 1997, respectively.

WP&L employees also participate in defined contribution pension plans (401(k)
plans) covering substantially all employees.  WP&L's contributions to the
plans, which are based on the participants' level of contribution, were $2.0
million, $2.4 million and $2.8 million in 1999, 1998 and 1997, respectively.

(9)   DEBT
(a)   Short-Term Debt - WP&L participates in a utility money pool with IESU
and IPC that is funded, as needed, through the issuance of commercial paper
by Alliant Energy.  Interest expense and other fees are allocated based on
borrowing amounts.  The PSCW has restricted WP&L from lending money to
non-utility affiliates and non-Wisconsin utilities.  As a result, WP&L is
prohibited from lending money to the utility money pool but is able to borrow
money from the utility money pool.  Information regarding short-term debt is
as follows (dollars in millions):

</TABLE>


The carrying amount of WP&L's current assets and current liabilities
approximates fair value because of the short maturity of such financial
instruments.  The nuclear decommissioning trust funds realized gains from the
sales of securities of $4.1 million, $0.8 million and $0.1 million in 1999,
1998 and 1997, respectively (cost of the investments based on specific
identification were $86.2 million, $57.6 million and $54.0 million,

                                      112

respectively).  Since WP&L is subject to regulation, any gains or losses
related to the difference between the carrying amount and the fair value of
its financial instruments may not be realized by WP&L's parent.

(12)  COMMITMENTS AND CONTINGENCIES
(b)  Purchased-Power, Coal and Natural Gas Contracts - Corporate Services has
entered into purchased-power capacity contracts as agent for WP&L, IESU and
IPC.  Based on the System Coordination and Operating Agreement, Alliant
Energy annually allocates purchased-power contracts to the individual
utilities.  Such process considers factors such as resource mix, load growth
and resource availability.  See Note 17 for additional information.  In
addition, Corporate Services has entered into various coal contracts as agent
for WP&L, IESU and IPC.  Contract quantities are allocated to specific plants
at the individual utilities based on various factors including projected heat
input requirements, combustion compatibility and efficiency.  However, in
2000 and 2001, system-wide contracts of $24.6 million (6.5 million tons) and
$12.5 million (3.6 million tons), respectively, have not yet been allocated
to the individual utilities due to the need for additional analysis of
combustion compatibility and efficiency.  The minimum commitments directly
assigned to WP&L are as follows (dollars in millions, tons in thousands):

                                          Coal
              Purchased-Power          (including

2004            25.2       219        5.4       2,957

Corporate Services is in the process of negotiating several new coal
contracts.  In addition, it expects to supplement its coal contracts with
spot market purchases to fulfill its future fossil fuel needs.  WP&L also has
various natural gas supply, transportation and storage contracts
outstanding.  The minimum dekatherm commitments, in millions, for 2000-2004
are 60.0, 44.9, 42.6, 34.6 and 7.4, respectively.  The minimum dollar
commitments for 2000-2004, in millions, are $27.9, $18.5, $14.6, $12.0 and
$1.9, respectively.  The gas supply commitments are all index-based.  WP&L
expects to supplement its natural gas supply with spot market purchases as
needed.

(c)   Information Technology Services - Alliant Energy has an agreement,
expiring in 2004, with EDS for information technology services.  WP&L's
anticipated operating and capital expenditures under the agreement for 2000
are estimated to total approximately $2 million.  Future costs under the
agreement are variable and are dependent upon WP&L's level of usage of
technological services from EDS.

(14)  SEGMENTS OF BUSINESS
WP&L is a regulated domestic utility, serving customers in Wisconsin and
Illinois, with three principal business segments: a) electric operations; b)
gas operations; and c) other, which includes water operations and the
unallocated portions of the utility business.  Intersegment revenues were not
material to WP&L's operations and there was no single customer whose revenues
exceeded 10% or more of WP&L's consolidated revenues.

*Earnings for 1998 were impacted by the recording of approximately $3
million, $11 million, $2 million and $1 million of pre-tax merger-related
expenses in the first, second, third and fourth quarters, respectively.

(17)  RELATED PARTY ISSUES
In association with the merger, IESU, WP&L and IPC entered into a System
Coordination and Operating Agreement which became effective with the merger.
The agreement, which has been approved by FERC, provides a contractual basis
for coordinated planning, construction, operation and maintenance of the
interconnected electric generation and transmission systems of the three
utility companies.  In addition, the agreement allows the interconnected
system to be operated as a single entity with off-system capacity sales and
purchases made to market excess system capability or to meet system
capability deficiencies.  Such sales and purchases are allocated among the
three utility companies based on procedures included in the agreement.  The
sales amounts allocated to WP&L were $23.8 million and $23.6 million for 1999
and 1998, respectively.  The purchases allocated to WP&L were $101.0 million
and $70.0 million for 1999 and 1998, respectively.  The procedures were
approved by both the FERC and all state regulatory bodies having jurisdiction
over these sales.  Under the agreement, IESU, WP&L and IPC are fully
reimbursed for any generation expense incurred to support a sale to an
affiliate or to a non-affiliate.  Any margins on sales to non-affiliates are
distributed to the three utilities in proportion to each utility's share of
electric production at the time of the sale.

Pursuant to a service agreement approved by the SEC under PUHCA, WP&L
received various administrative and general services from an affiliate,
Corporate Services.  These services are billed to WP&L at cost based on
payroll and other expenses incurred by Corporate Services for the benefit of
WP&L.  These costs totaled $96.5 million and $53.9 million for 1999 and 1998,
respectively, and consisted primarily of employee compensation, benefits and
fees associated with various professional services.  Corporate Services began
operations in May 1998 upon the consummation of the merger.

At December 31, 1999 and 1998, WP&L had an intercompany payable to Corporate
Services of $24.7 million and $20.0 million, respectively.

                        Effective as of March 15, 2000


ARTICLE I
                                   OFFICES

Section 1.1 PRINCIPAL AND BUSINESS  OFFICES.  - The  Corporation may have such
principal and other  business  offices,  either within or without the State of
Wisconsin,  as the Board of Directors  may designate or as the business of the
Corporation may require from time to time.

Section 1.2 REGISTERED  OFFICE.  - The  registered  office of the  Corporation
required by the  Wisconsin  Business  Corporation  Law to be maintained in the
State of  Wisconsin  may be,  but need not be,  identical  with the  principal
office in the State of  Wisconsin,  and the address of the  registered  office
may be  changed  from  time  to  time  by the  Board  of  Directors  or by the

ARTICLE III
                                 SHAREOWNERS

Section 3.1 ANNUAL  MEETING.  - The  annual  meeting of the  shareowners  (the
"Annual  Meeting")  shall  be held at  such  date  and  time as the  Board  of
Directors  may  determine.  In fixing a meeting  date for any Annual  Meeting,
the Board of Directors may consider such factors as it deems  relevant  within
the good faith  exercise of its  business  judgment.  At each Annual  Meeting,
the  shareowners  shall elect that number of directors  equal to the number of
directors  in the class  whose term  expires at the time of such  meeting.  At
any such Annual  Meeting,  only other  business  properly  brought  before the
meeting in  accordance  with Section  3.14 of these Bylaws may be  transacted.
If the  election  of  directors  shall not be held on the date fixed as herein
provided,  for any Annual Meeting,  or any adjournment  thereof,  the Board of
Directors  shall  cause  the  election  to be held  at a  special  meeting  of
shareowners (a "Special Meeting") as soon thereafter as is practicable.
<PAGE>

Section 3.2 SPECIAL  MEETINGS.  - A Special  Meeting may be called only by (i)
the  Board of  Directors  or (ii) the  Chief  Executive  Officer  and shall be
called by the Chief  Executive  Officer upon the demand,  in  accordance  with
this  Section  3.2, of the holders of record of shares  representing  at least
10%  of all  the  votes  entitled  to be  cast  on any  issue  proposed  to be
considered at the Special Meeting.

(a)   In order that the Corporation may determine the shareowners  entitled to
demand a Special  Meeting,  the Board of  Directors  may fix a record  date to
determine the  shareowners  entitled to make such a demand (the "Demand Record
Date").  The  Demand  Record  Date shall not  precede  the date upon which the
resolution  fixing the Demand Record Date is adopted by the Board of Directors
and shall not be more than ten days after the date upon  which the  resolution
fixing  the Demand  Record  Date is  adopted  by the Board of  Directors.  Any
shareowner  of record  seeking to have  shareowners  demand a Special  Meeting
shall,  by sending  written notice to the Secretary of the Corporation by hand
or by certified or registered  mail,  return  receipt  requested,  request the
Board of Directors to fix a Demand Record Date.  The Board of Directors  shall
promptly,  but in all  events  within ten days after the date on which a valid
request to fix a Demand  Record Date is received,  adopt a  resolution  fixing
the Demand  Record  Date and shall make a public  announcement  of such Demand
Record  Date.  If no  Demand  Record  Date  has  been  fixed  by the  Board of
Directors  within ten days after the date on which such request is received by
the  Secretary,  the Demand  Record Date shall be the 10th day after the first
date on which a valid written  request to set a Demand Record Date is received
by the  Secretary.  To be  valid,  such  written  request  shall set forth the
purpose or  purposes  for which the  Special  Meeting is to be held,  shall be
signed by one or more shareowners of record (or their duly authorized  proxies
or other  representatives),  shall  bear the date of  signature  of each  such
shareowner  (or  proxy  or other  representative)  and  shall  set  forth  all
information  about  each such  shareowner  and about the  beneficial  owner or
owners,  if any, on whose behalf the request is made that would be required to
be set forth in a  shareowner's  notice  described  in  paragraph  (a) (ii) of
Section 3.14 of these Bylaws.

(b)   In order for a shareowner or shareowners to demand a Special Meeting,  a
written  demand or demands  for a Special  Meeting by the holders of record as
of the  Demand  Record  Date of  shares  representing  at least 10% of all the
votes  entitled  to be cast on any  issue  proposed  to be  considered  at the
Special  Meeting  must be  delivered  to the  Corporation.  To be valid,  each
written  demand  by a  shareowner  for a Special  Meeting  shall set forth the
specific  purpose  or  purposes  for which the  Special  Meeting is to be held
(which  purpose or purposes  shall be limited to the  purpose or purposes  set
forth in the  written  request to set a Demand  Record  Date  received  by the
Corporation  pursuant to paragraph (b) of this Section  3.2),  shall be signed
by one or more  persons who as of the Demand  Record Date are  shareowners  of
record (or their duly  authorized  proxies  or other  representatives),  shall
bear  the  date of  signature  of each  such  shareowner  (or  proxy  or other
representative),  and shall set forth the name and address,  as they appear in
the Corporation's  books, of each shareowner signing such demand and the class
and  number  of  shares of the  Corporation  which  are  owned of  record  and
beneficially by each such  shareowner,  shall be sent to the Secretary by hand
or by certified or registered  mail,  return receipt  requested,  and shall be
received by the Secretary within seventy days after the Demand Record Date.
<PAGE>

(c)   The  Corporation  shall not be required to call a Special  Meeting  upon
shareowner demand unless,  in addition to the documents  required by paragraph
(c) of this Section 3.2, the Secretary  receives a written agreement signed by
each  Soliciting  Shareowner  (as  defined  below),  pursuant  to  which  each
Soliciting Shareowner,  jointly and severally, agrees to pay the Corporation's
costs of holding the Special  Meeting,  including  the costs of preparing  and
mailing proxy materials for the Corporation's own solicitation,  provided that
if each of the  resolutions  introduced by any  Soliciting  Shareowner at such
meeting is adopted,  and each of the individuals  nominated by or on behalf of
any  Soliciting  Shareowner  for  election  as a director  at such  meeting is
elected,  then the  Soliciting  Shareowners  shall not be required to pay such
costs.  For purposes of this  paragraph  (d), the  following  terms shall have
the meanings set forth below:

(i)   "Affiliate"  of any Person  (as  defined  herein)  shall mean any Person
      controlling,  controlled  by or under  common  control  with  such
      first Person.

(ii)  "Participant"  shall  have the  meaning  assigned  to such  term in Rule
      14a-11  promulgated under the Securities  Exchange Act of 1934, as
      amended (the "Exchange Act").

(iii) "Person"  shall mean any  individual,  firm,  corporation,  partnership,
      joint venture, association,  trust, unincorporated organization or
      other entity.

(iv)  "Proxy"  shall  have the  meaning  assigned  to such term in Rule  14a-1
      promulgated under the Exchange Act.

(v)   "Solicitation"  shall  have the  meaning  assigned  to such term in Rule
      14a-11 promulgated under the Exchange Act.

(vi)  "Soliciting  Shareowner" shall mean, with respect to any Special Meeting
      demanded by a  shareowner  or  shareowners,  any of the  following
      Persons:

(A)   if the number of  shareowners  signing  the demand or demands of meeting
            delivered  to the  Corporation  pursuant to  paragraph
            (c)  of  this  Section  3.2  is  ten  or  fewer,  each
            shareowner signing any such demand;


(B)   if the number of  shareowners  signing  the demand or demands of meeting
            delivered  to the  Corporation  pursuant to  paragraph
            (c) of this Section 3.2 is more than ten,  each Person
            who either (I) was a Participant  in any  Solicitation
            of such  demand or  demands or (II) at the time of the
            delivery   to  the   Corporation   of  the   documents
            described  in  paragraph  (c) of this  Section 3.2 had
            engaged or intends  to engage in any  Solicitation  of
            Proxies for use at such Special  Meeting (other than a
            Solicitation    of    Proxies   on   behalf   of   the
            Corporation); or
<PAGE>

(C)   any  Affiliate  of  a  Soliciting  Shareowner,  if  a  majority  of  the
            directors then in office determine,  reasonably and in
            good faith,  that such Affiliate should be required to
            sign the written notice  described in paragraph (c) of
            this   Section  3.2  and/or  the   written   agreement
            described  in this  paragraph  (d) in order to prevent
            the purposes of this Section 3.2 from being evaded.

(d)   Except as provided in the following sentence,  any Special Meeting shall
be held at such hour and day as may be  designated  by  whichever of the Board
of Directors or the Chief  Executive  Officer  shall have called such meeting.
In the case of any Special Meeting called by the Chief Executive  Officer upon
the demand of shareowners (a "Demand Special Meeting"),  such meeting shall be
held at such  hour and day as may be  designated  by the  Board of  Directors;
provided,  however,  that the date of any Demand Special  Meeting shall be not
more than  seventy  days after the Meeting  Record Date (as defined in Section
3.6 hereof);  and provided  further that in the event that the directors  then
in office  fail to  designate  an hour and date for a Demand  Special  Meeting
within ten days after the date that valid written  demands for such meeting by
the holders of record as of the Demand Record Date of shares  representing  at
least 10% of all the votes  entitled  to be cast on each issue  proposed to be
considered  at the  Special  Meeting are  delivered  to the  Corporation  (the
"Delivery  Date"),  then such meeting shall be held at 2:00 P.M. local time on
the 100th day after the Delivery  Date or, if such 100th day is not a Business
Day (as  defined  below),  on the first  preceding  Business  Day. In fixing a
meeting  date for any Special  Meeting,  the Board of  Directors  or the Chief
Executive  Officer may consider such factors as it or he deems relevant within
the good faith exercise of its or his business  judgment,  including,  without
limitation,  the  nature of the  action  proposed  to be taken,  the facts and
circumstances  surrounding  any demand for such  meeting,  and any plan of the
Board of  Directors  to call an Annual  Meeting or a Special  Meeting  for the
conduct of related business.

(e)   The   Corporation  may  engage   regionally  or  nationally   recognized
independent  inspectors of elections to act as an agent of the Corporation for
the purpose of promptly  performing  a  ministerial  review of the validity of
any purported  written demand or demands for a Special Meeting received by the
Secretary.  For the  purpose of  permitting  the  inspectors  to perform  such
review,  no  purported  demand  shall be deemed to have been  delivered to the
Corporation  until the earlier of (i) five Business Days following  receipt by
the Secretary of such purported  demand and (ii) such date as the  independent
inspectors  certify to the Corporation  that the valid demands received by the
Secretary  represent at least 10% of all the votes entitled to be cast on each
issue proposed to be considered at the Special Meeting.  Nothing  contained in
this  paragraph (f) shall in any way be construed to suggest or imply that the
Board of  Directors  or any  shareowner  shall not be  entitled to contest the
validity  of any  demand,  whether  during  or after  such five  Business  Day
period,  or to take any  other  action  (including,  without  limitation,  the
commencement, prosecution or defense of any litigation with respect thereto).
<PAGE>

(f)   For purposes of these  Bylaws,  "Business  Day" shall mean any day other
than a Saturday,  a Sunday or a day on which banking institutions in the State
of Wisconsin are authorized or obligated by law or executive order to close.

Section 3.3 PLACE OF MEETING.  - The Board of Directors or the Chief Executive
Officer  may  designate  any  place,  either  within or  without  the State of
Wisconsin,  as the place for any Annual Meeting or any Special Meeting, or for
any  postponement  thereof.  If no  designation  is made, the place of meeting
shall  be  the  principal  office  of  the  Corporation.  Any  meeting  may be
adjourned  to  reconvene  at any  place  designated  by vote of the  Board  of
Directors or determined by the Chief Executive Officer.

Section 3.4 NOTICE OF MEETINGS - Written  notice  stating  the date,  time and
place of any meeting of shareowners  shall be delivered not less than ten days
nor more than seventy days before the date of the meeting  (unless a different
time period is  provided  by the  Wisconsin  Business  Corporation  Law or the
Articles  of  Incorporation),  either  personally  or by  mail,  by or at  the
direction of the Chief Executive Officer or the Secretary,  to each shareowner
of record  entitled  to vote at such  meeting  and to such  other  persons  as
required  by the  Wisconsin  Business  Corporation  Law.  In the  event of any
Demand  Special  Meeting,  such notice of meeting  shall be sent not more than
thirty  days after the  Delivery  Date.  For  purposes  of this  Section  3.4,
notice by  "electronic  transmission"  (as such  term is  defined  in  Section
180.0103(7m) of the Wisconsin  Business  Corporation  Law") shall be deemed to
constitute  written notice.  Written notice pursuant to this Section 3.4 shall
be deemed to be effective  (a) when mailed,  if mailed  postpaid and addressed
to the  shareowner's  address  shown in the  Corporation's  current  record of
shareowners  or (b) when  electronically  transmitted  to the  shareowner in a
manner  authorized  by  the  shareowner.  Unless  otherwise  required  by  the
Wisconsin Business Corporation Law or the Articles of Incorporation,  a notice
of an Annual  Meeting need not include a description  of the purpose for which
the meeting is called.  In the case of any Special Meeting,  (i) the notice of
meeting  shall  describe any business  that the Board of Directors  shall have
theretofore  determined  to bring before the meeting and (ii) in the case of a
Demand Special Meeting,  the notice of meeting (A) shall describe any business
set  forth  in the  statement  of  purpose  of  the  demands  received  by the
Corporation  in  accordance  with  Section  3.2 of these  Bylaws and (B) shall
contain  all  of  the  information  required  in the  notice  received  by the
Corporation in accordance with Section  3.14(b) of these Bylaws.  If an Annual
Meeting or Special  Meeting is adjourned to a different  date,  time or place,
the Corporation  shall not be required to give notice of the new date, time or
place if the new  date,  time or  place is  announced  at the  meeting  before
adjournment;  provided,  however,  that if a new  Meeting  Record  Date for an
adjourned  meeting is or must be fixed,  the Corporation  shall give notice of
the  adjourned  meeting to persons who are  shareowners  as of the new Meeting
Record Date.
<PAGE>

Section 3.5 WAIVER OF NOTICE - A shareowner  may waive any notice  required by
the  Wisconsin  Business  Corporation  Law, the Articles of  Incorporation  or
these  Bylaws  before or after the date and time  stated  in the  notice.  The
waiver  shall be in  writing  and  signed by the  shareowner  entitled  to the
notice,  contain  the same  information  that would have been  required in the
notice under applicable  provisions of the Wisconsin Business  Corporation Law
(except  that the  time  and  place of  meeting  need  not be  stated)  and be
delivered  to the  Corporation  for  inclusion  in the  corporate  records.  A
shareowner's  attendance at any Annual Meeting or Special  Meeting,  in person
or by proxy,  waives objection to all of the following:  (a) lack of notice or
defective  notice of the meeting,  unless the  shareowner  at the beginning of
the  meeting or  promptly  upon  arrival  objects to  holding  the  meeting or
transacting  business at the meeting;  and (b)  consideration  of a particular
matter at the meeting that is not within the purpose  described in the meeting
notice,  unless the shareowner  objects to  considering  the matter when it is
presented.

Section 3.6 FIXING  OF  RECORD  DATE.  - The  Board  of  Directors  may fix in
advance a date not less than ten days and not more than  seventy days prior to
the date of an Annual  Meeting or Special  Meeting as the record  date for the
determination  of  shareowners  entitled  to notice  of,  or to vote at,  such
meeting  (the  "Meeting  Record  Date").  In the  case of any  Demand  Special
Meeting,  (i) the  Meeting  Record  Date  shall be not later than the 30th day
after the Delivery  Date and (ii) if the Board of  Directors  fails to fix the
Meeting  Record Date  within  thirty days after the  Delivery  Date,  then the
close of  business  on such 30th day shall be the  Meeting  Record  Date.  The
shareowners  of record on the  Meeting  Record  Date shall be the  shareowners
entitled  to notice of and to vote at the  meeting.  Except as provided by the
Wisconsin  Business  Corporation  Law  for  a  court-ordered   adjournment,  a
determination  of  shareowners  entitled to notice of and to vote at an Annual
Meeting or Special  Meeting is effective for any  adjournment  of such meeting
unless the Board of Directors fixes a new Meeting Record Date,  which it shall
do if the  meeting  is  adjourned  to a date more than 120 days after the date
fixed  for the  original  meeting.  The  Board  of  Directors  may also fix in
advance a date as the record date for the purpose of  determining  shareowners
entitled to take any other  action or  determining  shareowners  for any other
purpose.  Such  record date shall be not more than  seventy  days prior to the
date  on  which  the  particular  action,   requiring  such  determination  of
shareowners,  is to be taken.  The  record  date for  determining  shareowners
entitled to a distribution  (other than a  distribution  involving a purchase,
redemption  or  other  acquisition  of the  Corporation's  shares)  or a share
dividend  is  the  date  on  which  the  Board  of  Directors  authorizes  the
distribution  or  share  dividend,  as the case may be,  unless  the  Board of
Directors fixes a different record date.

Section 3.7 SHAREOWNER   LIST.  -  The   Corporation   shall  have  available,
beginning  two (2) days after the notice of the meeting is given for which the
list was  prepared  and  continuing  to the date of the  meeting,  a  complete
record  of  each  shareowner   entitled  to  vote  at  such  meeting,  or  any
adjournment thereof,  showing the address of and number of shares held by each
shareowner.  The  shareowner  list shall be available  for  inspection  by any
shareowner during normal business hours at the Corporation's  principal office
or at a place  identified in the meeting  notice in the city where the meeting
will be held. The Corporation  shall make the  shareowners'  list available at
the meeting and any  shareowner  or his agent or attorney may inspect the list
at any time the meeting or any adjournment thereof.
<PAGE>

Section 3.8 QUORUM AND VOTING REQUIREMENTS.

(a)   Shares  entitled to vote as a separate voting group may take action on a
matter at any  Annual  Meeting or  Special  Meeting  only if a quorum of those
shares  exists with respect to that matter.  If the  Corporation  has only one
class of stock  outstanding,  such class shall  constitute  a separate  voting
group for purposes of this Section  3.8.  Except as otherwise  provided in the
Articles  of  Incorporation  or the  Wisconsin  Business  Corporation  Law,  a
majority of the votes  entitled to be cast on the matter  shall  constitute  a
quorum  of the  voting  group  for  action  on that  matter.  Once a share  is
represented  for any purpose at any Annual Meeting or Special  Meeting,  other
than for the  purpose of  objecting  to  holding  the  meeting or  transacting
business at the meeting,  it is considered present for purposes of determining
whether  a  quorum  exists  for  the  remainder  of the  meeting  and  for any
adjournment  of that  meeting  unless a new Meeting  Record Date is or must be
set for the adjourned meeting.  If a quorum exists,  except in the case of the
election of directors,  action on a matter shall be approved if the votes cast
within the voting  group  favoring the action  exceed the votes cast  opposing
the action,  unless the Articles of  Incorporation  or the Wisconsin  Business
Corporation  Law  requires  a greater  number  of  affirmative  votes.  Unless
otherwise  provided in the  Articles  of  Incorporation,  each  director to be
elected  shall be  elected  by a  plurality  of the votes  cast by the  shares
entitled to vote in the election of directors at an Annual  Meeting or Special
Meeting at which a quorum is present.

(b)   The Board of Directors  acting by resolution may postpone and reschedule
any  previously  scheduled  Annual  Meeting  or  Special  Meeting;   provided,
however,  that a Demand  Special  Meeting  shall not be  postponed  beyond the
100th day following the Delivery Date.  Any Annual Meeting or Special  Meeting
may be adjourned from time to time,  whether or not there is a quorum,  (i) at
any time,  upon a resolution by shareowners if the votes cast in favor of such
resolution  by the holders of shares of each voting group  entitled to vote on
any matter  theretofore  properly brought before the meeting exceed the number
of votes cast  against such  resolution  by the holders of shares of each such
voting group or (ii) at any time prior to the  transaction  of any business at
such meeting,  by the  Chairperson of the Board or pursuant to a resolution of
the  Board  of  Directors.  No  notice  of the time  and  place  of  adjourned
meetings  need  be  given  except  as  required  by  the  Wisconsin   Business
Corporation  Law. At any adjourned  meeting at which a quorum shall be present
or  represented,  any  business  may  be  transacted  which  might  have  been
transacted at the meeting as originally notified.

Section 3.9 CONDUCT OF MEETING.  - The  Chairperson of the Board shall preside
at each  meeting of  shareowners.  In the  absence of the  Chairperson  of the
Board,  such  persons,  in the  following  order,  shall  act as  chair of the
meeting;  the Vice Chairperson of the Board, the Chief Executive Officer,  the
President,  any  Vice  President,  and the  Director  in  attendance  with the
longest  tenure in that  office.  The  Secretary,  or if absent,  an Assistant
Secretary, of the Company shall act as Secretary of each shareowner meeting.

Section 3.10      PROXIES.  - At any  Annual  Meeting or  Special  Meeting,  a
shareowner  entitled  to vote may  vote  his or her  shares  in  person  or by
proxy. A shareowner  entitled to vote at an Annual Meeting or Special  Meeting
may authorize  another  person to act for the  shareowner  by  appointing  the
person  as proxy.  Without  limiting  the  manner  in which a  shareowner  may
appoint  a  proxy,  a  shareowner  or  the  shareowner's  authorized  officer,
director,  employee, agent or attorney-in-fact may use any of the following as
a valid means to make such an appointment:
<PAGE>

            (a)   Appointment  of a proxy in writing by signing or causing the
shareowner's  signature to be affixed to an appointment form by any reasonable
means, including, but not limited to, by facsimile signature.

            (b)   Appointment of a proxy by  transmitting  or authorizing  the
transmission  of an electronic  transmission  of the appointment to the person
who will be appointed as proxy or to a proxy  solicitation firm, proxy support
service  organization or like agent  authorized to receive the transmission by
the person  who will be  appointed  as proxy.  Every  electronic  transmission
shall  contain,  or be  accompanied  by,  information  that  can  be  used  to
reasonably  determine  that  the  shareowner  transmitted  or  authorized  the
transmission  of  the  electronic   transmission.   Any  person  charged  with
determining  whether a shareholder  transmitted or authorized the transmission
of the electronic  transmission  shall specify the information  upon which the
determination is made.

An appointment of a proxy is effective  when a signed  appointment  form or an
electronic  transmission  of the  appointment  is received by the inspector of
election or the  officer or agent of the  Corporation  authorized  to tabulate
votes.  An  appointment  is valid for eleven months unless a different  period
is expressly provided in the appointment.  Unless otherwise provided,  a proxy
may be revoked any time before it is voted,  either by  appointing a new proxy
in accordance  with the Wisconsin  Business  Corporation Law or by oral notice
given by the  shareowner  to the  presiding  officer  during the meeting.  The
presence of a shareowner  who has made an effective  proxy  appointment  shall
not itself  constitute a  revocation.  The Board of  Directors  shall have the
power  and  authority  to  make  rules  establishing  presumptions  as to  the
validity and sufficiency of proxies.

Section 3.11      VOTING OF SHARES.  - Except as provided  in the  Articles of
Incorporation  or statute,  each  outstanding  share entitled to vote shall be
entitled to one (1) vote upon each matter  submitted to a vote at a meeting of
shareowners.

Section 3.12      VOTING OF SHARES BY CERTAIN  HOLDERS.  - Shares  standing in
the name of another  corporation may be voted by such officer,  agent or proxy
as the Bylaws of such  corporation  may prescribe,  or, in the absence of such
provision, as the Board of Directors of such corporation may determine.

            Shares   held  by  an   administrator,   executor,   guardian   or
conservator  may be  voted by such  person,  either  in  person  or by  proxy,
without a transfer of such shares into that  person's  name.  Shares  standing
in the name of a trustee may be voted by such trustee,  either in person or by
proxy,  without  a  transfer  of such  shares  into the  trustee's  name.  The
Corporation may request  evidence of such fiduciary status with respect to the
vote, consent, waiver, or proxy appointment.
<PAGE>

            Shares   standing  in  the  name  of  a  receiver  or  trustee  in
bankruptcy  may be voted by such  receiver or  trustee,  and shares held by or
under the  control of a receiver  may be voted by such  receiver  without  the
transfer  of the  shares  into such  person's  name if  authority  so to do is
contained  in an  appropriate  order of the court by which such  receiver  was
appointed.

            A pledgee,  beneficial  owner, or  attorney-in-fact  of the shares
held in the name of a shareholder  shall be entitled to vote such shares.  The
Corporation  may request  evidence of such  signatory's  authority to sign for
the  shareholder  with  respect  to  the  vote,  consent,   waiver,  or  proxy
appointment.

            Neither  treasury  shares nor shares held by another  corporation,
if a majority of the shares  entitled to vote for the election of Directors of
such  other  corporation  is held by the  Corporation,  shall  be voted at any
meeting or counted in determining  the total number of  outstanding  shares at
any given time.

Section 3.13      Action without  Meeting.  - Any action required or permitted
by the  Articles of  Incorporation  or these  Bylaws or any  provision  of the
Wisconsin  Business  Corporation  Law to be  taken  at an  Annual  Meeting  or
Special  Meeting  may be taken  without a  meeting  if a  written  consent  or
consents,  describing the action so taken, is signed by all of the shareowners
entitled to vote with respect to the subject  matter  thereof and delivered to
the Corporation for inclusion in the corporate records.

all of the members of the  Committee  of  Directors,  as the case may be. Such
consent shall have the same force and effect as a unanimous  vote at a meeting

<PAGE>

      Section 3.6 QUORUM AND VOTING  REQUIREMENTS.  - Shares  entitled to vote
as a separate  voting group may take action on a matter at a meeting only if a
quorum of those shares  exists with respect to that matter.  A majority of the
outstanding  shares entitled to vote on a matter,  represented in person or by
proxy,  shall  constitute  a quorum  for  action on that  matter.  If a quorum
exists,  except in the case of the election of  directors,  action on a matter
shall be approved if the votes cast  favoring the action exceed the votes cast
opposing the action, unless the Corporation's  Articles of Incorporation,  any
Bylaw  adopted under  authority  granted in the Articles of  Incorporation  or
statute  requires a greater number of affirmative  votes.  Directors  shall be
elected by a  plurality  of the votes cast by the shares  entitled  to vote in
the election of  directors  at a meeting at which a quorum is present.  Though
less than a quorum of the outstanding  votes are  represented at a meeting,  a
majority of the votes so  represented  may  adjourn  the meeting  from time to
time  without  further  notice.  At such  adjourned  meeting at which a quorum
shall be present or  represented,  any business may be transacted  which might
have been transacted at the meeting as originally notified.

      Section  3.7 CONDUCT OF MEETING.  - The  Chairperson  of the Board shall
preside at each meeting of  shareowners.  In the absence of the Chairperson of
the Board,  such persons,  in the following  order,  shall act as chair of the
meeting;  the Vice Chairperson of the Board, the Chief Executive Officer,  the
President,  any Vice  President,  the Director in attendance  with the longest
tenure in that office.  The Secretary,  or if absent, an Assistant  Secretary,
of the Company shall act as Secretary of each shareowner.

      Section  3.8  PROXIES.  - At any Annual  Meeting or Special  Meeting,  a
shareowner  entitled  to vote may  vote  his or her  shares  in  person  or by
proxy. A shareowner  entitled to vote at an Annual Meeting or Special  Meeting
may authorize  another  person to act for the  shareowner  by  appointing  the
person  as proxy.  Without  limiting  the  manner  in which a  shareowner  may
appoint  a  proxy,  a  shareowner  or  the  shareowner's  authorized  officer,
director,  employee, agent or attorney-in-fact may use any of the following as
a valid means to make such an appointment:

            (a)   Appointment  of a proxy in writing by signing or causing the
shareowner's  signature to be affixed to an appointment form by any reasonable
means, including, but not limited to, by facsimile signature.

      (b)   Appointment  of  a  proxy  by   transmitting  or  authorizing  the
transmission  of an electronic  transmission  of the appointment to the person
who will be appointed as proxy or to a proxy  solicitation firm, proxy support
service  organization or like agent  authorized to receive the transmission by
the person  who will be  appointed  as proxy.  Every  electronic  transmission
shall  contain,  or be  accompanied  by,  information  that  can  be  used  to
reasonably  determine  that  the  shareowner  transmitted  or  authorized  the
transmission  of  the  electronic   transmission.   Any  person  charged  with
determining  whether a shareholder  transmitted or authorized the transmission
of the electronic  transmission  shall specify the information  upon which the
determination is made.
<PAGE>

An appointment of a proxy is effective  when a signed  appointment  form or an
electronic  transmission  of the  appointment  is received by the inspector of
election or the  officer or agent of the  Corporation  authorized  to tabulate
votes.  An  appointment  is valid for eleven months unless a different  period
is expressly provided in the appointment.  Unless otherwise provided,  a proxy
may be revoked any time before it is voted,  either by  appointing a new proxy
in accordance  with the Wisconsin  Business  Corporation Law or by oral notice
given by the  shareowner  to the  presiding  officer  during the meeting.  The
presence of a shareowner  who has made an effective  proxy  appointment  shall
not itself  constitute a  revocation.  The Board of  Directors  shall have the
power  and  authority  to  make  rules  establishing  presumptions  as to  the
validity and sufficiency of proxies.


      Section 3.9 VOTING OF SHARES.  - Except as  provided in the  Articles of
Incorporation  or statute,  each  outstanding  share entitled to vote shall be
entitled to one (1) vote upon each matter  submitted to a vote at a meeting of
shareowners.

      Section 3.10 VOTING OF SHARES BY CERTAIN  HOLDERS.  - Shares standing in
the name of another  corporation may be voted by such officer,  agent or proxy
as the Bylaws of such  corporation  may prescribe,  or, in the absence of such
provision, as the Board of Directors of such corporation may determine.

      Shares held by an administrator,  executor,  guardian or conservator may
be voted by such person,  either in person or by proxy,  without a transfer of
such  shares  into  that  person's  name.  Shares  standing  in the  name of a
trustee may be voted by such trustee,  either in person or by proxy, without a
transfer of such shares into the trustee's  name. The  Corporation may request
evidence of such fiduciary status with respect to the vote,  consent,  waiver,
or proxy appointment.

      Shares   standing   in  the   name  of  a   receiver   or   trustee   in
bankruptcy  may be voted by such  receiver or  trustee,  and shares held by or
under  the  control  of a  receiver  may be  voted  by such  receiver  without
the  transfer  of  the  shares  into  such   person's  name  if  authority  so
to do is  contained  in an  appropriate  order  of the  court  by  which  such
receiver was appointed.

      A pledgee,  beneficial owner, or  attorney-in-fact of the shares held in
the  name of a  shareholder  shall  be  entitled  to  vote  such  shares.  The
Corporation  may request  evidence of such  signatory's  authority to sign for
the  shareholder  with  respect  to  the  vote,  consent,   waiver,  or  proxy
appointment.
<PAGE>

      Neither  treasury  shares nor shares held by another  corporation,  if a
majority of the shares  entitled to vote for the election of Directors of such
other  corporation is held by the  Corporation,  shall be voted at any meeting
or counted in determining the total number of outstanding  shares at any given
time.

Meeting.  For a period of five (5) years  following April 21, 1998, no person,
except any of the initial  Directors serving as such on April 21, 1998, who is

Director must submit their  resignation  from the Board to the  Nominating and
Governance   Committee.   The  Nominating  and  Governance   Committee   shall
recommend  to the Board of  Directors  whether  the Board  should  accept such
resignation.   If  the   Nominating  and   Governance   Committee   recommends
acceptance  of the  resignation,  an  affirmative  vote of  two-thirds  of the
remaining  Directors  holding  office is required to affirm the Nominating and
Governance  Committee's  recommendation.  A resignation may be tendered by any

shares  held  by  or  under  the  control  of  a  receiver  may  be

the  written  request  of  such  Principal   Stockholder  (the   "Transferring
Stockholder")  and except as otherwise  provided in Section 3.1(b) and Section
3.2, each other Principal  Stockholder shall,  notwithstanding  the provisions
of this Section  3.1(a),  have the right to Transfer a percentage of the total
number of Securities  beneficially  owned by such Principal  Stockholder equal
to the percentage of the total number of Securities  beneficially owned by the
Transferring  Stockholder  that the Board of Directors  has  consented  may be
Transferred by such  Transferring  Stockholder.  The parties  acknowledge that
any Transfer  pursuant to this Section  3.1(a) to which the Board of Directors
has consented may be in  connection  with, or as part of, a private  placement
by the Company of, or other transaction involving, its Securities.

            (b)   In addition to the  provisions  of Section  3.1(a),  for the
period commencing for the quarter ending  December 31,  1999 and ending on the
Expiration  Date, the Board shall determine prior to the public release of the
<PAGE>

Company's  consolidated  financial results with respect to each such financial
reporting quarter during such period,  the aggregate number, if any, of shares
of  Class A  Common  Stock  (not to  exceed  in the  aggregate  three  hundred
thousand  (300,000)  shares of Class A Common  Stock per  quarter,  subject to
adjustment  pursuant to Section 5.1) that may be  Transferred by the Principal
Stockholders  (the  "Transfer  Amount")  during the period  commencing  on the
third (3rd) business day and ending on the  twenty-third  (23rd)  business day
following such public release of the Company's  quarterly or annual  financial
results or such other  trading  period  designated  or  permitted by the Board
with respect to the purchase and sale of its Securities  (each such period,  a
"Transfer  Period").  Notwithstanding  the provisions of Section 3.1(a),  each
Principal  Stockholder  shall be  entitled to  Transfer  during each  Transfer
Period,  provided such Transfer is effected in accordance  with all applicable
federal and state  securities laws, a number of shares of Class A Common Stock
equal to thirty-three and one-third  percent (33 1/3%) of the Transfer Amount,
if any, for such Transfer Period  (rounding down in the case of any fractional
amount).  Any portion of any  Principal  Stockholder's  share of the  Transfer
Amount  that  such  Principal  Stockholder  elects  not to  transfer  during a
Transfer  Period shall be  reallocated  equally among the remaining  Principal
Stockholders  who intend to  Transfer  shares of Class A Common  Stock  during
such Transfer  Period,  and such  remaining  Principal  Stockholders  shall be
entitled to Transfer  such  additional  shares of Class A Common  Stock during
the Transfer  Period,  provided such  Transfer is effected in accordance  with
all  applicable  federal  and state  securities  laws.  In no event  shall any
portion of a Transfer  Amount that is not utilized by a Principal  Stockholder
during  a  Transfer  Period  be  reallocated  or  otherwise  credited  to  any
subsequent Transfer Periods.

            (c)   For  the   period   commencing   for  the   quarter   ending
December 31,  1999 and ending on the  Expiration  Date, the Company shall give
each Principal  Stockholder  prompt written notice (in any event no later than
fifty (50) days prior to the beginning of the applicable  Transfer  Period) of
its  determination  of any Transfer  Amount.  Within seven (7) days of receipt
of such notice,  any Principal  Stockholder that desires to Transfer shares of
Class A Common Stock during such Transfer  Period  pursuant to Section  3.1(b)
shall  provide  written  notice  to the  Company  of the  number  of shares of
Class A  Common  Stock that such  Principal  Stockholder  desires to  Transfer
pursuant  to Section  3.1(b).  Not later than seven (7) days after  receipt of
such responses,  the Company shall notify all remaining Principal Stockholders
of any  Principal  Stockholder's  election not to Transfer the total number of
shares of Class A Common Stock that such Principal  Stockholder is entitled to
Transfer during such Transfer Period.  Any Principal  Stockholder that desires
to Transfer  additional shares of Class A Common Stock equal to all or part of
the remaining  Transfer  Amount shall notify the Company within seven (7) days
of receipt of the Company's  second  notice.  The Company  shall  allocate the
remaining  Transfer Amount in accordance with the provisions of Section 3.1(b)
and shall notify the appropriate Principal  Stockholders of such allocation no
later than ten (10) days prior to the beginning of the Transfer Period.

            (d)   For  purposes of this  Section  3.1,  the  McLeods  shall be
deemed  to be a  single  Principal  Stockholder,  Lumpkin  and  all of the CCI
Shareholders shall be deemed to be a single Principal  Stockholder and the AEC
Entities shall be deemed to be a single Principal Stockholder.

      3.2   Registration Rights

            (a)   In the event that the Board of Directors  consents  pursuant
to Section 3.1(a) to a Principal  Stockholder's  request for a Transfer and in
connection  therewith,  the Company agrees to register Securities with respect
to  such  Transfer   under  the  Securities  Act  of  1933,  as  amended  (the
"Securities  Act"),  the Company shall grant each other Principal  Stockholder
the opportunity  (subject to reduction in the event the registered Transfer is
underwritten)  to register for Transfer  under the Securities Act a percentage
of the  total  number  of  Securities  beneficially  owned  by such  Principal
Stockholder  equal  to  the  percentage  of the  total  number  of  Securities
beneficially  owned by the  Transferring  Stockholder  that such  Transferring
Stockholder is registering  for Transfer under the Securities Act, on the same
terms  and  conditions  as  the  Transferring   Stockholder   (each  Principal
Stockholder  registering,  or indicating a desire to register,  any Securities
for  Transfer  under the  Securities  Act pursuant to this Section 3.2 being a
"Registering Transferor").

            (b)   To the extent  that the Company  grants  pursuant to Section
3.1(b) a Principal  Stockholder  the opportunity to register shares of Class A
Common Stock for Transfer  under the  Securities  Act, the Company shall grant
each other Principal  Stockholder the opportunity (subject to reduction in the
event the registered  Transfer is underwritten) to register an equal number of
shares of Class A Common Stock for Transfer  under the  Securities  Act on the
same terms and conditions.

            (c)   In the event the Company  proposes to register any shares of
Class A Common  Stock under the  Securities  Act  pursuant to an  underwritten
primary offering (other than pursuant to a registration  statement on Form S-4
or Form S-8 or any  successor  forms  thereto or other  form  which  would not
permit the  inclusion of the shares of Class A Common  Stock of the  Principal
Stockholders),  the Company,  as determined  by the Board of Directors,  shall
give written notice to all Principal  Stockholders  of its intention to effect
such a registration.  Following any such notice,  the Board of Directors shall
undertake  to determine  the  aggregate  number,  if any, of shares of Class A
Common  Stock  held  by the  Principal  Stockholders  (not  to  exceed  in the
aggregate  on a per year  basis a number  of  shares  of Class A Common  Stock
equal to  fifteen  percent  (15%) of the  total  number  of  shares of Class A
Common Stock beneficially  owned by the Principal  Stockholders as of December
31, 1998,  subject to appropriate and proportionate  adjustment as a result of
the Stock  Split and  subject to  adjustment  pursuant  to Section  5.1) to be
registered by the Company under the Securities Act (the "Registrable  Amount")
for Transfer by the Principal  Stockholders  in connection with such offering.
<PAGE>

If the Board  determines  to register  shares of Class A Common  Stock held by
the Principal  Stockholders  pursuant to this Section 3.2(c), the Company will
promptly  give  written  notice  of  such   determination   to  all  Principal
Stockholders,  and  thereupon  the Company  will use  commercially  reasonable
efforts to effect the  registration of that portion of the Registrable  Amount
that the Registering  Transferors indicate a desire to register.  In the event
the Registering  Transferors  indicate a desire to register a number of shares
of Class A Common  Stock  that,  in the  aggregate,  exceeds  the  Registrable
Amount,  the number of shares of Class A Common  Stock  that each  Registering
Transferor  shall be entitled to register  shall be reduced to the extent such
number  exceeds  such   Registering   Transferor's   pro  rata  share  of  the
Registrable  Amount  based  upon the ratio of the total  number of  Securities
beneficially  owned by such  Registering  Transferor  to the  total  number of
Securities  beneficially  owned by all Principal  Shareholders.  To the extent
any  portion  of  the  Registrable  Amount  remains   unallocated  after  such
reductions,  each  Registering  Transferor  who  has  indicated  a  desire  to
register  additional  shares  of Class A Common  Stock  shall be  entitled  to
register  an  additional  amount  of  Class  A  Common  Stock  equal  to  such
Registering  Transferor's pro rata portion of the remaining Registrable Amount
based upon the ratio of the total number of Securities  beneficially  owned by
such  Registering  Transferor to the total number of  Securities  beneficially
owned by all  Registering  Transferors who have indicated a desire to register
additional  shares  of  Class  A  Common  Stock.  The  reallocation  procedure
described  in the  preceding  sentence  shall be  repeated  until  the  entire
Registrable  Amount is  allocated.  All  terms,  conditions  and  rights  with
respect to such  registration  (including but not limited to any determination
to reduce the Registrable  Amount) shall be determined by the Board,  provided
that (i) the representations  and warranties of a Principal  Stockholder shall
be  customary  taking  into  account,  among other  things,  the nature of the
offering and such Principal  Stockholder's  relationship with the Company, and
(ii) the Company  shall be  responsible  for all expenses with respect to such
registration  other than underwriting  discounts and commissions  allocable to
the Class A Common Stock of the Registering  Transferors,  which  underwriting
discounts  and  commissions  shall be the  responsibility  of the  Registering
Transferors.

            (d)   In addition to the  registration  rights granted pursuant to
Sections 3.2(a),  (b) and (c), no more frequently than once during each of the
calendar years ending  December 31,  2000 and 2001 (each such year, an "Annual
Period"),  and upon either (i) the receipt of a written request of one or more
Principal Stockholders or (ii) a determination by the Board of Directors,  the
Board shall  undertake  to  determine  the  Registrable  Amount,  if any,  for
Transfer by the Principal  Stockholders.  If the Board  determines to register
shares of Class A Common Stock held by the Principal  Stockholders pursuant to
this Section  3.2(d),  the Company will promptly  give written  notice of such
determination  to all Principal  Stockholders,  and thereupon the Company will
use  commercially  reasonable  efforts  to  effect  the  registration  of that
portion of the Registrable Amount that the Registering  Transferors indicate a
<PAGE>

desire to  register.  In the  event the  Registering  Transferors  indicate  a
desire to  register a number of shares of Class A Common  Stock  that,  in the
aggregate,  exceeds the  Registrable  Amount,  the number of shares of Class A
Common Stock that each  Registering  Transferor  shall be entitled to register
shall  be  reduced  to  the  extent  such  number  exceeds  such   Registering
Transferor's pro rata share of the Registrable  Amount based upon the ratio of
the  total  number  of  Securities  beneficially  owned  by  such  Registering
Transferor  to the  total  number  of  Securities  beneficially  owned  by all
Principal  Stockholders.  To the extent any portion of the Registrable  Amount
remains  unallocated  after such reductions,  each Registering  Transferor who
has indicated a desire to register  additional  shares of Class A Common Stock
shall be entitled to register  an  additional  amount of Class A Common  Stock
equal to such  Registering  Transferor's  pro rata  portion  of the  remaining
Registrable  Amount  based  upon the ratio of the total  number of  Securities
beneficially  owned by such  Registering  Transferor  to the  total  number of
Securities   beneficially  owned  by  all  Registering  Transferors  who  have
indicated  a desire to  register  additional  shares of Class A Common  Stock.
The  reallocation  procedure  described  in the  preceding  sentence  shall be
repeated  until  the  entire  Registrable  Amount  is  allocated.  All  terms,
conditions  and rights with respect to such  registration  (including  but not
limited  to any  determination  to reduce  the  Registrable  Amount)  shall be
determined by the Board,  provided that (i) the representations and warranties
of a Principal  Stockholder  shall be  customary  taking into  account,  among
other  things,  the nature of the  offering and such  Principal  Stockholder's
relationship  with the Company,  and (ii) the Company shall be responsible for
all  expenses  with  respect  to such  registration  other  than  underwriting
discounts and commissions,  which underwriting discounts and commissions shall
be the responsibility of the Registering Transferors.

            (e)   If  the  Board   establishes   a   committee   (a   "Pricing
Committee")  to  authorize  and  approve  the price and any other terms of any
Transfer of Securities  registered  under the  Securities Act pursuant to this
Section 3.2 in which  Lumpkin or any CCI  Shareholder  is  participating  as a
Registering  Transferor,  the  Company  will  use its  best  efforts  to cause
Lumpkin to be nominated to such Pricing Committee.  Notwithstanding  any other
provision  of this  Agreement,  to the extent the  Company has  undertaken  to
register  Securities  of the Principal  Stockholders  pursuant to this Section
3.2, the Company may  subsequently  determine not to register such  Securities
and may either not file a  registration  statement  or  otherwise  withdraw or
abandon  a  registration  statement  previously  filed  with  respect  to  the
registration of such Securities.

            (f)   For  purposes of this  Section  3.2,  the  McLeods  shall be
deemed  to be a  single  Principal  Stockholder,  Lumpkin  and  all of the CCI
Shareholders shall be deemed to be a single Principal  Stockholder and the AEC
Entities shall be deemed to be a single Principal Stockholder.

Stockholder  a  reasonable  opportunity  to  Transfer  Securities  pursuant to

3.    TRANSFERS OF SECURITIES


      3.1   Restrictions on Transfers

            (a)   Except as otherwise  provided in this Section 3.1 or Section
3.2, the M/C  Stockholders  hereby agree that until the  Expiration  Date, the
M/C Stockholders will not offer,  sell,  contract to sell, grant any option to
purchase, or otherwise dispose of, directly or indirectly,  ("Transfer"),  any

<PAGE>

equity  securities of the Company or any other securities  convertible into or
exercisable for such equity securities  ("Securities")  beneficially  owned by
such M/C  Stockholders as a result of the Merger  (including  distributions of
Securities  with  respect to such  Securities  and  Securities  acquired  as a
result of a stock split with respect to such Securities)  without submitting a
written  request to, and receiving the prior written  consent of, the Board of
Directors;   provided,   however,  that  the  M/C  Stockholders  may  transfer
Securities to any beneficial  owner or Affiliate of the M/C  Stockholders,  in
each case  provided  that (i) such  transfer  is done in  accordance  with the
transfer  restrictions  applicable to such Securities  under federal and state
securities  laws and  (ii)  the  transferee  agrees  to be bound by the  terms
hereof (as this  Agreement may be amended or amended and restated from time to
time) as an M/C  Stockholder  with  respect  to the shares  being  transferred
pursuant to this Section (any such M/C Stockholder  transferee pursuant to the
foregoing proviso, an"M/C Stockholder  Permitted  Transferee"),  and any such
transfer  shall not  constitute a"Transfer"  for purposes of this  Agreement.
Notwithstanding  the foregoing,  no party hereto shall avoid the provisions of
this Agreement by making one or more transfers to one or more M/C  Stockholder
Permitted  Transferees  and then at any time directly or indirectly  disposing
of all or any portion of such  party's  interest  in any such M/C  Stockholder
Permitted  Transferee.  In the event that the Board of  Directors  consents to
any Transfer of  Securities by a Principal  Stockholder  (for purposes of this
Agreement,  the term "Principal  Stockholder"  shall have the same meaning as
ascribed  to such  term in the  Second  Amended  and  Restated  November  1998
Stockholders'  Agreement) pursuant to Section 3.1(a) of the Second Amended and
Restated  November 1998  Stockholders'  Agreement upon the written  request of
such Principal Stockholder (the"Transferring  Principal  Stockholder") during
the period  commencing  on January 1, 2000 and ending on the  Expiration  Date
and except as  otherwise  provided  in Section  3.1(b) and Section 3.2 of this
Agreement, the M/C Stockholders shall,  notwithstanding the provisions of this
Section  3.1(a),  have the right to Transfer a percentage  of the total number
of  Securities  beneficially  owned  by  the  M/C  Stockholders  equal  to the
percentage  of the  total  number  of  Securities  beneficially  owned  by the
Transferring  Principal  Stockholder that the Board of Directors has consented
may be Transferred by such Transferring  Principal  Stockholder.  In the event
the Board of  Directors  consents  to any  Transfer of  Securities  by the M/C
Stockholders  pursuant to this Section 3.1(a) upon the written  request of the
M/C  Stockholders  (the "Transferring  M/C  Stockholders"),   and  except  as
otherwise  provided in Section  3.1(b) and  Section 3.2 of the Second  Amended
and  Restated   November  1998   Stockholders'   Agreement,   each   Principal
Stockholder  shall,  notwithstanding  the  provisions of Section 3.1(a) of the
Second Amended and Restated November 1998  Stockholders'  Agreement,  have the
right to Transfer a percentage of the total number of Securities  beneficially
owned by such  Principal  Stockholder  equal to the  percentage  of the  total
number of Securities  beneficially  owned by the Transferring M/C Stockholders
that  the  Board  of  Directors  has  consented  may be  Transferred  by  such
Transferring M/C Stockholders.
<PAGE>

            (b)   In addition to the  provisions  of Section  3.1(a),  for the
period  commencing for the quarter ending  December 31, 1999 and ending on the
Expiration  Date, the Board shall determine prior to the public release of the
Company's  consolidated  financial results with respect to each such financial
reporting quarter during such period,  the aggregate number, if any, of shares
of Class A Common Stock (not to exceed in the aggregate  one hundred  thousand
(100,000)  shares of Class A Common Stock per quarter,  subject to  adjustment
pursuant to Section 5.1) that may be Transferred by the M/C Stockholders  (the
"Transfer  Amount")  during the period  commencing on the third (3rd) business
day and ending on the  twenty-third  (23rd) business day following such public
release of the Company's  quarterly or annual financial  results or such other
trading  period  designated  or  permitted  by the Board  with  respect to the
purchase and sale of its Securities (each such period,  a"Transfer  Period").
Notwithstanding  the provisions of Section 3.1(a),  the M/C Stockholders shall
be entitled to Transfer  during each Transfer  Period,  provided such Transfer
is effected in accordance  with all  applicable  federal and state  securities
laws,  a  number  of  shares  of Class A Common  Stock  equal to the  Transfer
Amount,  if any, for such Transfer Period.  In no event shall any portion of a
Transfer  Amount  that  is not  utilized  by the  M/C  Stockholders  during  a
Transfer  Period  be  reallocated  or  otherwise  credited  to any  subsequent
Transfer  Periods.  Notwithstanding  the foregoing  provisions of this Section
3.1(b), to the extent that the Company permits the Principal  Stockholders the
opportunity  to Transfer  shares of Class A Common  Stock  pursuant to Section
3.1(b)  of  the  Second  Amended  and  Restated  November  1998  Stockholders'
Agreement  during the period  commencing  on January 1, 2000 and ending on the
Expiration  Date, the Company shall grant the M/C Stockholders the opportunity
to  Transfer  on the same terms and  conditions  a number of shares of Class A
Common  Stock equal to the number of shares which each  Principal  Stockholder
is entitled to Transfer pursuant to such Section 3.1(b),  without  considering
those  provisions  of  Section  3.1(b)  of the  Second  Amended  and  Restated
November 1998 Stockholders'  Agreement relating to the reallocation of amounts
among  the  Principal  Stockholders.  To the  extent  the Board  determines  a
Transfer  Amount  with  respect  to the M/C  Stockholders  for any  particular
quarter  pursuant to this Section  3.1(b),  the Board shall determine an equal
Transfer  Amount for such quarter with respect to each  Principal  Stockholder
pursuant to Section  3.1(b) of the Second  Amended and Restated  November 1998
Stockholders' Agreement.

            (c)   For the period  commencing for the quarter  ending  December
31, 1999 and ending on the  Expiration  Date,  the Company  shall give the M/C
Stockholders  prompt  written  notice  (in any event no later  than fifty (50)
days  prior  to  the  beginning  of the  applicable  Transfer  Period)  of its
determination  of any  Transfer  Amount.  Within  seven (7) days of receipt of
such notice,  the M/C Stockholders shall provide written notice to the Company
of the  number  of shares of Class A Common  Stock  that the M/C  Stockholders
desire to Transfer pursuant to Section 3.1(b).
<PAGE>
            (d)   During the year ending  December 31, 1999, to the extent the
Company  participates in a strategic  transaction with an outside  investor(s)
pursuant to which such  investor(s)  acquires  Securities  of the Company at a
premium to the then average  trading  price of the Company's  Securities,  and
after the Company has been paid or  otherwise  received its  consideration  or
proceeds from such  transaction  as  determined  by the Company,  the Original
Stockholders  and the M/C  Stockholders may be entitled to participate in such
transaction on a pro rata basis as determined by the Board of Directors.

            (e)   For  purposes  of this  Section  3.1,  the M/C  Stockholders
shall be deemed to be a single  stockholder of the Company,  the McLeods shall
be deemed to be a single  Principal  Stockholder  of the Company,  Lumpkin and
all  of  the  CCI  Shareholders  shall  be  deemed  to be a  single  Principal
Stockholder  of the  Company  and the AEC  Entities  shall be  deemed  to be a
single Principal Stockholder of the Company.


      3.2   Registration Rights

            (a)   In the event that the Board of Directors  consents  pursuant
to  Section  3.1(a)  of  the  Second   Amended  and  Restated   November  1998
Stockholders'  Agreement to a Principal  Stockholder's  request for a Transfer
during the period  commencing on January 1, 2000 and ending on the  Expiration
Date and in connection  therewith,  the Company agrees to register  Securities
with respect to such  Transfer  under the  Securities  Act of 1933, as amended
(the "Securities  Act"),  the Company  shall grant the M/C  Stockholders  the
opportunity  (subject to  reduction  in the event the  registered  Transfer is
underwritten)  to register for Transfer  under the Securities Act a percentage
of the total number of Securities  beneficially  owned by the M/C Stockholders
equal to the percentage of the total number of Securities  beneficially  owned
by the Transferring  Principal  Stockholder that such  Transferring  Principal
Stockholder is registering  for Transfer under the Securities Act, on the same
terms and conditions as the Transferring Principal  Stockholder.  In the event
that the  Board of  Directors  consents  pursuant  to  Section  3.1(a) of this
Agreement to the M/C Stockholders'  request for a Transfer,  and in connection
therewith  the Company  agrees to  register  Securities  with  respect to such
Transfer  under the  Securities  Act, the Company  shall grant each  Principal
Stockholder  pursuant to Section  3.1(a) of the Second  Amended  and  Restated
November 1998  Stockholders'  Agreement the opportunity  (subject to reduction
in the  event  the  registered  Transfer  is  underwritten)  to  register  for
Transfer  under  the  Securities  Act a  percentage  of the  total  number  of
Securities  beneficially  owned  by such  Principal  Stockholder  equal to the
percentage  of the  total  number  of  Securities  beneficially  owned  by the
Transferring  M/C  Stockholders  that such  Transferring  M/C Stockholders are
registering  under the Securities Act, on the same terms and conditions as the
Transferring M/C Stockholders.

            (b)   To the extent  that the Company  grants  pursuant to Section
3.1(b)  of  the  Second  Amended  and  Restated  November  1998  Stockholders'
Agreement a Principal  Stockholder the opportunity to register shares of Class

<PAGE>

A Common  Stock for  Transfer  under the  Securities  Act  during  the  period
commencing on January 1, 2000 and ending on the  Expiration  Date, the Company
shall grant the M/C Stockholders the opportunity  (subject to reduction in the
event the registered  Transfer is underwritten) to register an equal number of
shares of Class A Common Stock for Transfer  under the  Securities  Act on the
same terms and conditions,  without  considering  those  provisions of Section
3.1(b)  of  the  Second  Amended  and  Restated  November  1998  Stockholders'
Agreement  relating  to  the  reallocation  of  amounts  among  the  Principal
Stockholders.  To the  extent  that the  Company  grants  pursuant  to Section
3.1(b) of this  Agreement the M/C  Stockholders  the  opportunity  to register
shares of Class A Common  Stock for  Transfer  under the  Securities  Act, the
Company shall grant each Principal  Stockholder  pursuant to Section 3.1(b) of
the Second  Amended and Restated  November  1998  Stockholders'  Agreement the
opportunity  (subject to  reduction  in the event the  registered  Transfer is
underwritten)  to register an equal  number of shares of Class A Common  Stock
for Transfer under the Securities Act on the same terms and conditions.

            (c)   For the period  commencing  on January 1, 2000 and ending on
the Expiration  Date, in the event the Company proposes to register any shares
of Class A Common Stock under the Securities  Act pursuant to an  underwritten
primary offering (other than pursuant to a registration  statement on Form S-4
or Form S-8 or any  successor  forms  thereto or other  form  which  would not
permit  the  inclusion  of the  shares  of  Class A  Common  Stock  of the M/C
Stockholders),  the Company,  as determined  by the Board of Directors,  shall
give written notice to the M/C  Stockholders of its intention to effect such a
registration.  Following  any  such  notice,  the  Board  of  Directors  shall
undertake  to determine  the  aggregate  number,  if any, of shares of Class A
Common Stock held by the M/C  Stockholders  (not to exceed in the aggregate on
a per year basis a number of shares of Class A Common  Stock  equal to fifteen
percent  (15%)  of the  total  number  of  shares  of  Class  A  Common  Stock
beneficially  owned  by the M/C  Stockholders  as of the  Effective  Time  (as
defined in the Merger  Agreement) in connection  with the  consummation of the
Merger,  subject to appropriate  and  proportionate  adjustment as a result of
the Stock  Split and  subject to  adjustment  pursuant  to Section  5.1) to be
registered by the Company under the Securities Act (the"Registrable  Amount")
for Transfer by the M/C  Stockholders  in connection with such offering during
such  period.  If the Board  determines  to register  shares of Class A Common
Stock  held by the M/C  Stockholders  pursuant  to this  Section  3.2(c),  the
Company will promptly  give written  notice of such  determination  to the M/C
Stockholders,  and  thereupon  the Company  will use  commercially  reasonable
efforts to effect the  registration of that portion of the Registrable  Amount
that  the  M/C  Stockholders  indicate  a  desire  to  register.   All  terms,
conditions  and rights with respect to such  registration  (including  but not
limited  to any  determination  to reduce  the  Registrable  Amount)  shall be
determined by the Board,  provided that (i) the representations and warranties
of the M/C Stockholders  shall be customary  taking into account,  among other
things,  the nature of the  offering  and the M/C  Stockholders'  relationship
with the Company,  and (ii) the Company shall be responsible  for all expenses

<PAGE>

with  respect to such  registration  other  than  underwriting  discounts  and
commissions  allocable  to the Class A Common  Stock of the M/C  Stockholders,
which  underwriting  discounts and commissions shall be the  responsibility of
the  M/C  Stockholders.  Notwithstanding  the  foregoing  provisions  of  this
Section  3.2(c),  to the extent  that the Company  grants  pursuant to Section
3.2(c)  of  the  Second  Amended  and  Restated  November  1998  Stockholders'
Agreement the Principal  Stockholders  the  opportunity to register  shares of
Class A Common Stock for Transfer  under the  Securities Act during the period
commencing on January 1, 2000 and ending on the  Expiration  Date, the Company
shall grant the M/C  Stockholders  the opportunity to register shares of Class
A Common  Stock on a  substantially  similar  basis.  To the  extent  that the
Company  grants   pursuant  to  Section  3.2(c)  of  this  Agreement  the  M/C
Stockholders  the  opportunity to register  shares of Class A Common Stock for
Transfer  under the  Securities  Act, the Company  shall grant each  Principal
Stockholder  pursuant to Section  3.2(c) of the Second  Amended  and  Restated
November 1998  Stockholders'  Agreement the  opportunity to register shares of
Class A Common Stock on a substantially similar basis.

            (d)   In addition to the  registration  rights granted pursuant to
Sections 3.2(a),  (b) and (c), no more frequently than once during each of the
calendar years ending  December 31,  2000 and 2001 (each such year, an"Annual
Period"),  and upon  either (i) the  receipt  of a written  request of the M/C
Stockholders  or (ii) a  determination  by the Board of  Directors,  the Board
shall undertake to determine the Registrable  Amount,  if any, for Transfer by
the M/C  Stockholders.  If the Board  determines to register shares of Class A
Common Stock held by the M/C  Stockholders  pursuant to this  Section  3.2(d),
the Company will promptly  give written  notice of such  determination  to the
M/C Stockholders,  and thereupon the Company will use commercially  reasonable
efforts to effect the  registration of that portion of the Registrable  Amount
that  the  M/C  Stockholders  indicate  a  desire  to  register.   All  terms,
conditions  and rights with respect to such  registration  (including  but not
limited  to any  determination  to reduce  the  Registrable  Amount)  shall be
determined by the Board,  provided that (i) the representations and warranties
of the M/C Stockholders  shall be customary  taking into account,  among other
things,  the nature of the  offering  and the M/C  Stockholders'  relationship
with the Company,  and (ii) the Company shall be responsible  for all expenses
with  respect to such  registration  other  than  underwriting  discounts  and
commissions  allocable  to the Class A Common  Stock of the M/C  Stockholders,
which  underwriting  discounts and commissions shall be the  responsibility of
the  M/C  Stockholders.  Notwithstanding  the  foregoing  provisions  of  this
Section  3.2(d),  to the extent  that the Company  grants  pursuant to Section
3.2(d)  of  the  Second  Amended  and  Restated  November  1998  Stockholders'
Agreement the Principal  Stockholders  the  opportunity to register  shares of
Class A Common Stock for Transfer  under the  Securities Act during the period
commencing on January 1, 2000 and ending on the  Expiration  Date, the Company
shall grant the M/C  Stockholders  the opportunity to register shares of Class
A Common  Stock on a  substantially  similar  basis.  To the  extent  that the
Company  grants   pursuant  to  Section  3.2(d)  of  this  Agreement  the  M/C
Stockholders  the  opportunity to register  shares of Class A Common Stock for
Transfer  under the  Securities  Act, the Company  shall grant each  Principal
Stockholder  pursuant to Section  3.2(d) of the Second  Amended  and  Restated
November 1998  Stockholders'  Agreement the  opportunity to register shares of
Class A Common Stock on a substantially similar basis.

            (e)   For  purposes  of this  Section  3.2,  the M/C  Stockholders
shall be deemed to be a single  stockholder of the Company,  the McLeods shall
be deemed to be a single  Principal  Stockholder  of the Company,  Lumpkin and
all  of  the  CCI  Shareholders  shall  be  deemed  to be a  single  Principal
Stockholder  of the  Company  and the AEC  Entities  shall be  deemed  to be a

            (f)   Notwithstanding  any other provision of this  Agreement,  to
the extent the  Company  has  undertaken  to  register  Securities  of the M/C
Stockholders  pursuant to this  Section  3.2,  the  Company  may  subsequently
determine  not  to  register  such  Securities  and  may  either  not  file  a
registration  statement  or  otherwise  withdraw  or  abandon  a  registration
statement   previously   filed  with  respect  to  the  registration  of  such
Securities;  provided that to the extent the Principal  Stockholders  are also
participating  in such  registration,  the M/C  Stockholders and the Principal
Stockholders will be treated on a substantially  similar basis with respect to
any  such  determination  not to  register  Securities  or the  withdrawal  or
abandonment of a registration  statement  previously  filed as contemplated by
this Section 3.2(f).
