ITEM 1.      DESCRIPTION OF PROPOSED TRANSACTION.
             ------------------------------------

             A. Background. Alliant Energy Corporation ("Alliant Energy") is a
                ----------
registered holding company under the Public Utility Holding Company Act of 1935
(the "Act"). Its direct and indirect public utility subsidiaries are: Interstate
Power and Light Company (formerly IES Utilities Inc.)(1) ("IP&L"), Wisconsin
Power and Light Company ("WP&L"), and South Beloit Water, Gas & Electric Company
("South Beloit") (collectively the "Utility Subsidiaries"). Together, the
Utility Subsidiaries provide service to approximately 930,000 electric and
398,000 gas utility customers in parts of Wisconsin, Iowa, Minnesota and
Illinois.

             Alliant Energy's direct non-utility subsidiaries include Alliant
Energy Corporate Services, Inc. ("Alliant Services"), a subsidiary service
company, and Alliant Energy Resources, Inc. ("AER"), which serves as the holding
company for substantially all of Alliant Energy's non-utility investments and
subsidiaries. AER owns seven principal direct subsidiaries, which engage,
directly and indirectly through other subsidiaries, in (i) providing
environmental consulting and engineering services, (ii) the development,
ownership and management of investments in affordable multi-unit housing
properties, (iii) providing various financial services, including the
origination and sale of mortgages for tax-advantaged affordable housing, (iv)
energy-related businesses, including, among others, the brokering and marketing
of electricity and natural gas, gas supply and fuel management services, oil and
gas production, steam production and sale, and energy-management services, (v)
owning and/or operating "exempt wholesale generators" ("EWGs"), as defined in
Section 32 of the Act, and "foreign utility companies" ("FUCOs"), as defined in
Section 33 of the Act, (vi) transportation, and (vii) management of investments
in telecommunications. AER and its direct and indirect non-utility subsidiaries
are herein referred to as the "Non-Utility Subsidiaries."

             B. Current Short-term Debt/Money Pool Authorization. By order dated
                ------------------------------------------------
December 18, 1998 in File No. 70-9317 (Holding Co. Act Release No. 26956), as
modified and extended by order dated December 15, 2000 (Holding Co. Act Release
No. 27304) (as so modified and extended, the "Current Money Pool Order"),
Alliant Energy is authorized to issue notes and/or commercial paper from time to
time through June 30, 2004, and to fund separate money pools for intrasystem
borrowings by the Utility Subsidiaries (other than South Beloit) and the
Non-Utility Subsidiaries. Specifically, Alliant Energy is authorized to issue
and sell notes and/or commercial paper in an aggregate principal amount at any
time outstanding not to exceed $1 billion and to utilize the proceeds of such
borrowings to make loans through the system utility money pool ("Utility Money
Pool") to IP&L, WP&L and Alliant Services in an aggregate amount not to exceed
$475 million in 2001 and $525 million through the remainder of the authorization
period, and for other corporate purposes, including, among others, funding of
temporary investments in EWGs and FUCOs. At December 31, 2001, Alliant Energy

--------------
(1)   By order dated October 24, 2001 (Holding Co. Act Release No. 27456),
      the Commission approved the merger of Interstate Power Company ("IPC"),
      which, at that time, was also a direct wholly-owned subsidiary of Alliant
      Energy, and IES Utilities Inc. ("IES"), with IES as the surviving company.
      The merger of IPC into IES was effective as of January 1, 2002, and, in
      connection therewith, IES changed its name to Interstate Power and Light
      Company.

                                       4


had issued and outstanding $68.4 million of commercial paper notes.

             Alliant Energy is also authorized under the Current Money Pool
Order to provide guarantees or enter into expense agreements or otherwise
provide credit support in an amount not to exceed $600 million at any time
outstanding in order to support a separate commercial paper program established
by AER, which is used to fund the Alliant Energy system non-utility money pool
("Non-Utility Money Pool").

             Under the terms of the Current Money Pool Order, Alliant Energy is
authorized to issue commercial paper in denominations of not less than $100,000
to dealers at rates not to exceed the rate per annum prevailing at the time of
issuance for commercial paper of comparable qualities and maturities. Alliant
Energy may also issue commercial paper to institutions if the resulting cost of
money would be equal to or less than that available from dealer-placed
commercial paper or bank borrowings. Commercial paper notes may have maturities
of up to 270 days and must be rated at least A-1 by Standard & Poor's ("S&P") or
at least P-1 by Moody's Investor Services ("Moody's"). Borrowings by Alliant
Energy from banks may bear interest at a rate no higher than the effective cost
of money for unsecured prime commercial bank loans prevailing at the date of
borrowing.

             Under the Current Money Pool Order, as modified by the Commission's
order approving the merger of IPC into IES,(2) IP&L is authorized to borrow up
to $250 million at any one time outstanding under the Utility Money Pool.
Borrowings by WP&L and Alliant Services under the Utility Money Pool are exempt
pursuant to Rule 52(a) in the case of WP&L and Rule 52(b) in the case of Alliant
Services. WP&L's participation in the Utility Money Pool as a borrower but not
as a lender has been approved by the Public Service Commission of Wisconsin
("PSCW").(3)

             At December 31, 2001, the outstanding borrowings under the Utility
Money Pool by WP&L, IP&L (IES and IPC combined) and Alliant Services were $90.8
million, $38.1 million, and $36.1 million, respectively. The effective cost of
funds borrowed under the Utility Money Pool is currently 2.87%.

             As indicated, AER has established a separate commercial paper
program and bank credit facilities totaling $600 million, which are used to fund
loans under the Non-Utility Money Pool to the participating Non-Utility
Subsidiaries (as listed in Item 1.F, below). Alliant Energy currently guarantees
all commercial paper notes issued by AER, as well as borrowings under the bank

-------------------
(2)   See n. 1, above.
      --- -

(3)   WP&L is currently authorized by the PSCW to make short-term borrowings
      under the Utility Money Pool in an aggregate principal amount outstanding
      at any one time not to exceed $240 million. Under Wisconsin law, WP&L is
      prohibited from making any loan to any affiliate, including any loan of
      surplus funds through a system money pool arrangement.


                                       5




credit facilities maintained by AER.(4) At December 31, 2001, AER had issued and
outstanding $383.6 million of commercial paper notes.

             C. Specific Authorizations Requested. In this Application or
                ---------------------------------
Declaration, the applicants seek to restate, modify and extend their
authorization under the Current Money Pool Order for the period through December
31, 2004 ("Authorization Period"). Specifically, authorization is requested for
each of the following proposed transactions:

          1. Alliant Energy requests authority to issue and sell from time to
          time commercial paper, notes to banks and other forms of short-term
          indebtedness ("Short-term Debt") in an aggregate principal amount at
          any time outstanding not to exceed $1 billion (its current
          authorization) and to utilize the proceeds thereof to fund loans to
          IP&L and Alliant Services through the Utility Money Pool and to AER
          and the other participating Non-Utility Subsidiaries through the
          Non-Utility Money Pool, and for other corporate purposes, including
          funding of investments in EWGs and FUCOs. WP&L intends to terminate
          its participation in the Utility Money Pool and is therefore not an
          applicant in this proceeding.

          2. IP&L requests authorization to issue and sell Short-term Debt in a
          principal amount which, when added to the principal amount of any
          borrowings by IP&L under the Utility Money Pool, will not at any time
          exceed $300 million. To the extent required, the Utility Money Pool
          participants request authorization to make loans and extend credit to
          each other under the Utility Money Pool.(5)

          3. Alliant Energy seeks to have the flexibility to either guarantee
          borrowings by AER to fund the Non-Utility Money Pool, as is currently
          the case, or to make direct loans to the Non-Utility Money Pool.
          Accordingly, as an alternative to making direct loans to the
          Non-Utility Money Pool, Alliant Energy requests authorization to
          guarantee borrowings by AER in an aggregate amount not to exceed $700
          million at any time outstanding to fund loans to Non-Utility
          Subsidiaries through the Non-Utility Money Pool.(6)

          4. Alliant Energy, on behalf of itself and its participating Utility
          and Non-Utility Subsidiaries, proposes to maintain and continue the
          operation of the Utility Money Pool and the Non-Utility Money Pool,
          with certain changes described below.


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

(4)   The Commission noted in the Current Money Pool Order that Rule 52 exempts
      AER's financing arrangements that comply with its terms.

(5)   Borrowings by and extensions of credit to Alliant Services under the
      Utility Money Pool will be exempt pursuant to Rules 52 and 45(b)(1).

(6)   The guaranty authority requested herein is in addition to the guaranty
      authority that Alliant Energy has obtained in File No. 70-9891 (Holding
      Co. Act Release No. 27448, Oct. 3, 2001).


                                       6


             Upon the effective date of the Commission's order in this
proceeding, the applicants will relinquish their authority under the Current
Money Pool Order, as modified by the terms of the Commission's October 24, 2001
order approving the merger of IPC into IES.

             D. Reasons for Proposed Changes in Short-term Borrowing
                ----------------------------------------------------
Arrangements. Under the Current Money Pool Order, short-term borrowings and/or
------------
commercial paper sales by Alliant Energy represent the only source of external
funds that are available for short-term borrowings by IP&L, WP&L and Alliant
Services; none of these companies currently maintains any external short-term
credit facilities, and IP&L has no authority under the Current Money Pool Order
to incur short-term indebtedness, other than through the Utility Money Pool.(7)
Until recently, Alliant Energy's commercial paper was rated A-1 by S&P and P-1
by Moody's. Thus, Alliant Energy's effective cost of funds was equal to or lower
than the effective cost of funds that any of the Utility Money Pool participants
could have obtained on its own by issuing commercial paper and other forms of
short-term notes to lenders other than Alliant Energy. Alliant Energy and the
other Utility Money Pool participants were also able to realize administrative
cost reductions by consolidating all short-term borrowing arrangements at the
Alliant Energy level. Recently, however, Alliant Energy's commercial paper was
downgraded to A-2 by S&P and to P-2 by Moody's. Under the Current Money Pool
Order, Alliant Energy is not authorized to issue commercial paper unless it is
rated at least A-1 by S&P or at least P-1 by Moody's. Thus, without the relief
requested herein, Alliant Energy is effectively foreclosed from issuing
commercial paper in amounts exceeding that permitted by Section 6(b) of the Act,
even though commercial paper rated A-2/P-2 continues to represent Alliant
Energy's lowest cost short-term borrowing option.(8)

             Furthermore, with the downgrading of its commercial paper rating,
Alliant Energy has determined that IP&L and WP&L may have the ability to issue
commercial paper or other forms of short-term debt at a lower effective cost
than Alliant Energy. Accordingly, as described below, IP&L is seeking authority
in this proceeding to issue Short-term Debt directly when such borrowings would
have a lower effective cost than borrowings under the Utility Money Pool. Also,
because of the downgrading in Alliant Energy's commercial paper, it is no longer
possible for WP&L to participate in the Utility Money Pool as a borrower. WP&L
will therefore establish its own external short-term funding arrangements and
terminate its participation in the Utility Money Pool. External short-term
borrowings by WP&L will be exempt under Rule 52(a).

             E. Description of Short-term Debt. Alliant Energy and IP&L propose
                ------------------------------
to issue and sell from time to time Short-term Debt in the form of commercial
paper notes, bank notes, and other forms of short-term indebtedness. All
Short-term Debt will have maturities of less than one year from the date of
issuance. Alliant Energy requests authority to issue up to $1.0 billion of
Short-term Debt at any time outstanding, and IP&L requests authorization to
issue Short-term Debt and/or incur borrowings under the Utility Money Pool in an


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

(7)   Although external borrowings by WP&L and Alliant Services would be
      exempt under Rule 52, both companies currently satisfy all of their
      requirements for short-term indebtedness through borrowings under the
      Utility Money Pool.

(8)   Since December 1, 2001, Alliant Energy has relied upon the exemption
      afforded by Section 6(b) of the Act to issue commercial paper.

                                       7


aggregate principal amount at any time outstanding not to exceed $300 million.

             Alliant Energy proposes to use up to $350 million of the proceeds
of Short-term Debt at any one time outstanding to make loans to IP&L and Alliant
Services through the Utility Money Pool and up to $700 million at any one time
outstanding to make loans to the Non-Utility Subsidiaries through the
Non-Utility Money Pool. IP&L also proposes to utilize proceeds of Short-term
Debt to make advances to the Utility Money Pool, but only to the extent that
such borrowing capacity is not required by IP&L in order to satisfy its own
needs.

             Commercial paper may be sold in established domestic or European
commercial paper markets. Such commercial paper would typically be sold to
dealers at the discount rate per annum prevailing at the date of issuance for
commercial paper of comparable quality and maturities sold to commercial paper
dealers generally. It is expected that the dealers acquiring such commercial
paper will reoffer it at a discount to corporate, institutional and, with
respect to European commercial paper, individual investors. It is anticipated
that such commercial paper will be reoffered to investors such as commercial
banks, insurance companies, pension funds, investment trusts, foundations,
colleges and universities, finance companies and nonfinancial corporations.

             Alliant Energy and IP&L may also establish and maintain back-up
credit lines with banks or other institutional lenders to support their
commercial paper program(s) and other credit arrangements and/or borrowing
facilities generally available to borrowers with comparable credit ratings as
they may deem appropriate in light of their needs and existing market conditions
providing for revolving credit or other loans and having commitment periods not
longer than the Authorization Period. Only the amounts drawn and outstanding
under these agreements and facilities will be counted against the proposed
limits on Short-term Debt.

             The effective cost of money on all Short-term Debt will not exceed
at the time of issuance 300 basis points over the London Interbank Offered Rate
("LIBOR") for maturities of one year or less.

             F.   Operation of Money Pools.
                  ------------------------

                  1. Utility Money Pool. Alliant Energy, IP&L and Alliant
                     ------------------
Services will continue to participate in the Utility Money Pool, which will be
operated and administered by Alliant Services in substantially the same manner
in which it now is, with the exception that funds made available to the Utility
Money Pool from external sources may be derived from external borrowings by
Alliant Energy or IP&L, or both. Filed herewith as Exhibit B-1 is a copy of the
proposed Amended and Restated Utility Money Pool Agreement, which incorporates
this alternative funding option.

             Under the proposed terms of the Amended and Restated Utility Money
Pool Agreement, funds would be available from the following sources for
short-term loans to the Utility Money Pool participants (other than Alliant
Energy) from time to time: (1) surplus funds in the treasuries of any of the



                                       8


Utility Money Pool participants ("Internal Funds"), and (2) proceeds received by
any of the Utility Money Pool participants from the issuance of Short-term Debt
("External Funds"), in each case to the extent permitted by applicable laws and
regulatory orders. Funds would be made available from such sources in such order
as Alliant Services, as the administrator of the Utility Money Pool, may
determine would result in a lower cost of borrowing, consistent with the
individual borrowing needs and financial standing of Utility Money Pool
participants that invest funds in the Utility Money Pool.

             Each Utility Money Pool participant that is authorized or permitted
to borrow from the Utility Money Pool would borrow pro rata from each Utility
Money Pool participant that advances funds to the Utility Money Pool in the
proportion that the total amount advanced by such participant bears to the total
amount then advanced to the Utility Money Pool by all participants. On any day
when more than one source of funds (i.e., both Internal Funds and External
Funds), with different rates of interest, are used to fund loans through the
Utility Money Pool, each borrowing participant would borrow pro rata from each
such funding source in the same proportion that the amount of funds provided by
that funding source bears to the total amount of funds advanced to the Utility
Money Pool.

             The cost of compensating balances, if any, and fees paid to banks
to maintain credit lines and accounts by Alliant Energy or IP&L that are used to
fund loans to the Utility Money Pool would initially be paid by the party
maintaining such credit lines and accounts. These costs would be retroactively
allocated every month among the Utility Money Pool borrowers in proportion to
each such borrowers' estimated peak short-term borrowing requirements.

            The daily outstanding balance of all loans to the Utility Money Pool
participants shall accrue interest as follows: (a) if only Internal Funds
comprise the daily outstanding balance of all loans outstanding during a
calendar month, the interest rate applicable to such daily balances shall be the
average for the month of the CD yield equivalent of the 30-day Federal Reserve
"AA" Industrial Commercial Paper Composite Rate (the daily rate, "Composite,"
and the monthly average of such Composite, the "Average Composite"), or, if no
such Composite was established for that particular day, then the applicable rate
would be the Composite for the next preceding day for which such Composite was
established, and (b) if only External Funds comprise the daily outstanding
balance of all loans outstanding during a calendar month, the interest rate
applicable to such daily outstanding balance shall be the lending participant's
cost for such External Funds or, if more than one participant had made available
External Funds at any time during the month, the applicable interest rate shall
be a composite rate, equal to the weighted average of the costs incurred by the
respective participants for such External Funds. In cases where the daily
outstanding balances of all loans outstanding at any time during the month
include both Internal Funds and External Funds, the interest rate applicable to
the daily outstanding balances for the month shall be the weighted average of
the (i) cost of all Internal Funds contributed by participants, and (ii) the
cost of all such External Funds. The interest rate paid on funds advanced to the
Utility Money Pool by any participant will be equal to the cost of borrowing
from the Utility Money Pool. That is, the applicable rate would be the Composite
rate in the case of Internal Funds, the lending company's cost of borrowing in
the case of External Funds, and a weighted average cost of funds if funds


                                       9


advanced to the Utility Money Pool at any one time consist of both Internal
Funds and External Funds.

            Funds not required by the Utility Money Pool participants to make
loans (with the exception of funds required to satisfy the Utility Money Pool's
liquidity requirements) would ordinarily be invested in one or more short-term
investments, including: (i) interest-bearing accounts with banks; (ii)
obligations issued or guaranteed by the U.S. government and/or its agencies and
instrumentalities, including obligations under repurchase agreements; (iv)
commercial paper rated not less than A-1 by S&P or P-1 by Moody's, or their
equivalent by a nationally recognized rating agency; (iii) obligations issued or
guaranteed by any state or political subdivision thereof, provided that such
obligations are rated not less than "A" by a nationally recognized rating
agency; (iv) bankers' acceptances; (v) money market funds; (vi) bank
certificates of deposit; (vii) Eurodollar funds; and (viii) such other
investments as are permitted by Section 9(c) of the Act and Rule 40 thereunder.

            Any income earned on investments of surplus funds would be allocated
at the end of each calendar month among those Utility Money Pool participants
that have invested funds in accordance with the proportion that each
participant's average contribution of funds in the Utility Money Pool for the
month bears to the total amount of funds invested in the Utility Money Pool for
the month.

            Each participant receiving a loan through the Utility Money Pool
would be required to repay the principal amount of such loan, together with all
interest accrued thereon, on demand and in any event within 365 days of the date
of such loan. All loans made through the Utility Money Pool may be prepaid by
the borrower without premium or penalty and without prior notice. No loans
through the Utility Money Pool would be made to, and no borrowings through the
Utility Money Pool would be made by, Alliant Energy.

                  2. Non-Utility Money Pool. The Non-Utility Money Pool will
continue to be operated on the same terms and conditions as the Utility Money
Pool, except that, as indicated above, instead of guaranteeing a separate
commercial paper facility maintained by AER to fund the Non-Utility Money Pool,
Alliant Energy intends for the foreseeable future to directly fund the
Non-Utility Money with up to $700 million of proceeds of commercial paper and
other short-term borrowings. This will enable AER to terminate its separate
commercial paper facility, thereby eliminating duplicate program costs.
Notwithstanding the foregoing, in the event that Alliant Energy subsequently
determines to restore AER's separate commercial paper facility, it seeks to have
the flexibility to guarantee borrowings by AER. Accordingly, Alliant Energy
requests authority to guarantee up to $700 million borrowings by AER in order to
fund the Non-Utility Money Pool in lieu of making direct advances to the
Non-Utility Money Pool in that amount. Filed herewith as Exhibit B-2 is a copy
of the proposed Amended and Restated Non-Utility Money Pool Agreement.

            The interest rates for Internal Funds and External Funds loaned
through or invested in the Non-Utility Money Pool will be determined in the same
manner as described above. All loans to, and borrowings from, the Non-Utility


                                       10


Money Pool are exempt pursuant to the terms of Rule 52 under the Act.

            In addition to Alliant Energy and AER, the following direct and
indirect subsidiaries of AER are currently participants in the Non-Utility Money
Pool:

            G. Reports. Alliant Services will continue to administer the Utility
               -------
and Non-Utility Money Pools and provide cash management and banking services to
the participants on an "at cost" basis. Alliant Services will prepare and file
reports pursuant to Rule 24 with respect to the external short-term financing
activity of Alliant Energy and IP&L and borrowings under the Utility Money Pool
and certificates on Form U-6B-2 pursuant to Rule 52 with respect to external


                                       11


short-term financing activity of AER and borrowings under the Non-Utility Money
Pool.(9) These reports will be filed within 45 days of the end of each calendar
quarter.

ITEM 2.      FEES, COMMISSIONS AND EXPENSES.
             ------------------------------

             The fees, commissions and expenses incurred or to be incurred in
connection with the transactions proposed herein are estimated at not more than
$75,000. Rating agency fees (for the commercial paper) and compensating balances
and other fees paid to banks to maintain the credit lines supporting the
commercial paper are included in the proposed limit on the effective cost of
money on Short-term Debt.

ITEM 3.      APPLICABLE STATUTORY PROVISIONS.
             -------------------------------

             A.   General.  Sections 6(a), 7, 9(a), 10, 12, 32 and 33 of the Act
                  --------
and Rules 24, 42, 43, 45 and 52 thereunder are applicable to the proposed
transactions.

                  B. Rule 53/54 Analysis. The proposed transactions are also
                     -------------------
subject to the requirements of Rules 53 and 54. Under Rule 53, in determining
whether to approve the issue or sale of any security (including any guarantee)
by a registered holding company for the purpose of financing the acquisition of
any EWG, the Commission may not make certain adverse findings under Sections 7
and 12 of the Act if the conditions set forth in paragraphs (a), (b) and (c) of
Rule 53 are satisfied. Rule 54 provides that in determining whether to approve
the issue or sale of a security by a registered holding company for purposes
other than the acquisition of an EWG or FUCO, or other transactions by such
registered holding company or its subsidiaries other than with respect to EWGs
or FUCOs, the Commission shall not consider the effect of the capitalization or
earnings of any subsidiary which is an EWG or a FUCO upon the registered holding
company if paragraphs (a), (b) and (c) of Rule 53 are satisfied.

         Alliant Energy currently does not meet all of the conditions of Rule
53(a). As of September 30, 2001, Alliant Energy's "aggregate investment," as
defined in Rule 53(a)(1), in EWGs and FUCOs was approximately $588.5 million, or
approximately 72.55% of Alliant Energy's average "consolidated retained
earnings," also as defined in Rule 53(a)(1), for the four quarters ended
September 30, 2001 ($811.2 million), which exceeds the 50% "safe harbor"
limitation contained in Rule 53(a). However, by order dated October 3, 2001
(Holding Co. Act Release No. 27448), the Commission has authorized Alliant
Energy to increase its "aggregate investment" in EWGs and FUCOs to an amount
equal to 100% of Alliant Energy's average "consolidated retained earnings."
Therefore, although Alliant Energy's "aggregate investment" in EWGs and FUCOs
currently exceeds the 50% "safe harbor" limitation, this investment level is
permitted under the October 3, 2001 order.

------------
(9)   In order to combine information on all Utility Money Pool activity in one
      report, it is proposed that information on borrowings by Alliant Services
      under the Utility Money Pool, although exempt pursuant to Rule 52, be
      combined with information on Utility Money Pool activity of the other
      Utility Money Pool participants on the Rule 24 reports rather than
      reported separately on Form U-6B-2.

                                       12


         In any event, even taking into account the capitalization of and
earnings from EWGs and FUCOs in which Alliant Energy has an interest, there
would be no basis for withholding approval of the proposed transaction. With
regard to capitalization, since the issuance of the October 3, 2001 order, there
has been no material adverse impact on Alliant Energy's consolidated
capitalization resulting from Alliant Energy's investments in EWGs and FUCOs. On
a pro forma basis, giving effect to a sale of common stock and issuance of
long-term debt in November 2001, Alliant Energy's consolidated capitalization
consists of 45.5% equity, 46.9% long-term debt, and 7.6% short-term debt
(including current maturities of long-term debt). These ratios are within
acceptable industry ranges. The transactions proposed herein merely continue
existing short-term funding arrangements at the same authorized levels. Hence,
the proposed transactions will not have any material impact on capitalization.
Finally, since the date of the October 3, 2001 order, there has been no material
change in Alliant Energy's level of earnings from EWGs and FUCOs.

         Alliant Energy satisfies all of the other conditions of paragraphs (a)
and (b) of Rule 53. With reference to Rule 53(a)(2), Alliant Energy maintains
books and records in conformity with, and otherwise adheres to, the requirements
thereof. With reference to Rule 53(a)(3), no more than 2% of the employees of
Alliant Energy's domestic public utility companies render services, at any one
time, directly or indirectly, to EWGs or FUCOs in which Alliant Energy directly
or indirectly holds an interest. With reference to Rule 53(a)(4), Alliant Energy
will continue to provide a copy of each application and certificate relating to
EWGs and FUCOs and relevant portions of its Form U5S to each regulator referred
to therein, and will otherwise comply with the requirements thereof concerning
the furnishing of information. With reference to Rule 53(b), none of the
circumstances enumerated in subparagraphs (1), (2) and (3) thereunder have
occurred. Finally, Rule 53(c) by its terms is inapplicable since the proposed
transaction does not involve the issue or sale of a security to finance the
acquisition of an EWG or FUCO.

ITEM 4.      REGULATORY APPROVALS.
             --------------------

             The participation by IP&L in the Utility Money Pool is subject to
the approval of Illinois Commerce Commission ("ICC") and the Minnesota Public
Utilities Commission ("MPUC"). No other state commission and no federal
commission, other than this Commission, has jurisdiction over the proposed
transactions.

ITEM 5.      PROCEDURE.
             ---------

             The Commission is requested to publish a notice under Rule 23 with
respect to the filing of this Application or Declaration as soon as practicable.
The applicants request that the Commission's order approving the proposed
transactions be issued as soon following the notice period as its rules permit.
The applicants further request that there should not be a 30-day waiting period
between issuance of the Commission's order and the date on which the order are
to become effective, hereby waive a recommended decision by a hearing officer or
any other responsible officer of the Commission, and consent that the Division
of Investment Management may assist in the preparation of the Commission's
decision and/or orders, unless the Division opposes the matters proposed herein.
