                                   THE COMPANY

         The Company was incorporated under the laws of the State of Iowa on May
25,  1925.  The Company is a public  utility  operating  company with all of its
operations  in the  State  of  Iowa  and  is a  wholly-owned  subsidiary  of IES
Industries Inc. ("Industries"), a public utility holding company. The Company is
the  surviving  corporation  following  the merger on December  31, 1993 of Iowa
Southern  Utilities  Company  ("Iowa  Southern"  or  "ISU")  with and into  Iowa
Electric  Light  and  Power  Company  ("IE").  The  surviving   corporation  was
subsequently renamed IES Utilities Inc.


                                       3


<PAGE>


         The Company supplies  electric energy and natural gas to a service area
with an estimated population of approximately one million. For the twelve months
ended March 31, 1997, the Company derived approximately 75% of its revenues from
the sale of electric energy,  approximately 22% from the sale of natural gas and
approximately  3% from the sale of steam gas.  At March 31,  1997,  the  Company
provided service to approximately 336,000 electric,  176,000 natural gas and 226
steam  retail  customers  as well as 30 resale  customers  in more than 550 Iowa
communities.  The Company's principal executive offices are located at 200 First
Street S.E., Cedar Rapids, Iowa 52401, telephone (319) 398-4411.

         Additional  information  concerning  the Company and its  operations is
contained in the Incorporated Documents, to which reference is hereby made.

                                   THE MERGER

         On November 10,  1995,  Industries,  WPL  Holdings,  Inc.  ("WPLH") and
Interstate  Power Company  ("IPC") entered into an Agreement and Plan of Merger,
as amended ("Merger Agreement"),  providing for: (a) IPC becoming a wholly-owned
subsidiary of WPLH, and (b) the merger of Industries  with and into WPLH,  which
merger will result in the combination of Industries and WPLH as a single holding
company  (collectively,  the "Proposed Merger"). The new holding company will be
named Interstate Energy  Corporation  ("Interstate  Energy") and Industries will
cease to exist. The Proposed Merger, which will be accounted for as a pooling of
interests and is intended to be tax-free for federal  income tax  purposes,  has
been  approved by the  respective  Boards of Directors and  shareholders.  It is
still subject to approval by several federal and state regulatory agencies.  The
companies  expect to receive  such  regulatory  approvals by the third or fourth
quarter of 1997.

         WPLH is a holding company headquartered in Madison,  Wisconsin,  and is
the parent company of Wisconsin  Power and Light Company  ("WP&L") and Heartland
Development  Corporation  ("HDC").  WP&L  supplies  electric  and gas service to
approximately 385,000 and 150,000 customers,  respectively, in south and central
Wisconsin. HDC and its principal subsidiaries are engaged in businesses in three
major areas:  environmental  engineering and consulting,  affordable housing and
energy  services.  IPC, an operating  public utility  headquartered  in Dubuque,
Iowa,  supplies  electric  and gas service to  approximately  165,000 and 49,000
customers,  respectively,  in northeast  Iowa,  northwest  Illinois and southern
Minnesota.

         Interstate Energy will be the parent company of Utilities, WP&L and IPC
and will be registered  under the Public Utility Holding Company Act of 1935, as
amended.  The Merger Agreement  provides that these operating  utility companies
will  continue  to operate as  separate  entities  for a minimum of three  years
beyond the effective date of the merger. In addition, the non-utility operations
of the Company and WPLH will be combined shortly after the effective date of the
merger  under one  entity to manage the  diversified  operations  of  Interstate
Energy.  The corporate  headquarters  of  Interstate  Energy will be in Madison,
Wisconsin.

         The Securities and Exchange Commission historically has interpreted the
1935 Act to preclude registered holding companies, with limited exceptions, from
owning both  electric  and gas utility  systems.  Although  the  Securities  and
Exchange Commission has recommended that registered holding companies be allowed
to hold both gas and electric  utility  operations if the affected states agree,
it remains possible that the Securities and Exchange Commission may require as a
condition to its approval of the Proposed Merger that the Company,  WPLH and IPC
divest their gas utility properties,  and possibly certain non-utility  ventures
of the Company and WPLH,  within a reasonable  time after the effective  date of
the Proposed Merger.

         Additional  information  concerning the Proposed Merger is contained in
the Incorporated Documents, to which reference is hereby made.

                                 USE OF PROCEEDS

         Except as otherwise provided in the applicable Prospectus Supplement or
a supplement thereto, the Company intends to use the net proceeds to be received
from the  issuance  and sale of the  Securities  offered  hereby  (i) to  reduce
short-term debt and (ii) for general corporate purposes.

                              PLAN OF DISTRIBUTION

         The Company may sell the  Securities in any of three ways:  (i) through
underwriters  or  dealers,  (ii)  directly to one or more  purchasers,  or (iii)
through agents. The applicable Prospectus Supplement will set forth the terms of
any  offering of the  Securities,  including  the names of any  underwriters  or
agents, the purchase price of such Securities,  the proceeds to the Company from
such sale, any underwriting discounts and other items constituting underwriters'
compensation,   the  initial  public  offering  price,   and  any  discounts  or
concessions allowed or reallowed or paid to dealers.

         If  underwriters  are used in the sale, the Securities will be acquired
by the underwriters for their own account and may be resold from time to time in
one or more transactions,  including negotiated transactions,  at a fixed public
offering  price or at  varying  prices  determined  at the  time of  sale.  Such
Securities may be offered to the public either through  underwriting  syndicates
represented by managing  underwriters  or by  underwriters  without a syndicate.
Unless  otherwise  set  forth  in  the  applicable  Prospectus  Supplement,  the
obligations of the  underwriters  to purchase such Securities will be subject to
certain conditions precedent, and the underwriters will be obligated to purchase
all of such  Securities if any of such  Securities  are  purchased.  The initial
public offering prices and any discounts or concessions  allowed or reallowed or
paid to dealers may be changed from time to time.

         The  Securities  may also be sold  directly  by the  Company or through
agents  designated by the Company from time to time.  Any agent  involved in the
offer or sale of the Securities will be named,  and any  commissions  payable by
the  Company  to such  agent will be set  forth,  in the  applicable  Prospectus
Supplement.  Unless otherwise indicated in the applicable Prospectus Supplement,
any such  agent  will act on a  reasonable  efforts  basis for the period of its
appointment.

         If so indicated in the applicable  Prospectus  Supplement,  the Company
will  authorize  agents,  underwriters,  or dealers to solicit offers by certain
specified  institutions  to purchase the Securities at the public offering price
set forth in such Prospectus  Supplement  pursuant to delayed delivery contracts
providing for payment and delivery on a future date specified in such Prospectus
Supplement or a supplement thereto. Such contracts will be subject only to those
conditions  set  forth  in  the  applicable  Prospectus  Supplement,   and  such
Prospectus Supplement will set forth the commissions payable for solicitation of
such contracts.

         Any underwriters,  dealers, or agents participating in the distribution
of the  Securities  may be  deemed  to be  underwriters,  and any  discounts  or
commissions  received  by them on the sale or  resale of the  Securities  may be
deemed to be underwriting  discounts and commissions,  under the Securities Act.
Agents and underwriters  may be entitled under agreements  entered into with the
Company to indemnification by the Company against certain liabilities, including
liabilities  under the Securities Act. Agents and  underwriters may be customers
of,  engage in  transactions  with,  or perform  services for the Company or its
affiliates in the ordinary course of business.


                    DESCRIPTION OF THE COLLATERAL TRUST BONDS

General

         If  the  Securities  are  issued  as  Collateral  Trust  Bonds,   those
Collateral  Trust Bonds will be issued in one or more series as fully registered
bonds, without coupons,  under an Indenture of Mortgage and Deed of Trust, dated
as of September 1, 1993 (the "Original  Mortgage"),  between the Company and The
First  National  Bank of Chicago,  as Trustee  (the  "Trustee"),  as amended and
supplemented.  As  used  herein,  the  term  "Bonds"  refers  to any  series  of
Collateral  Trust Bonds in respect of which this Prospectus is being  delivered.
The  Original  Mortgage  as amended  and  supplemented  by various  supplemental
indentures  including  one  or  more  supplemental  indentures  relating  to any
issuance  of  Collateral  Trust  Bonds,  is  hereinafter   referred  to  as  the
"Mortgage." The summaries  herein  concerning the Collateral  Trust Bonds do not
purport  to be  complete  and are  subject  to the  detailed  provisions  of the
Mortgage, a copy of which was previously filed with the Commission, is listed as
an exhibit to the Registration Statement of which this Prospectus is a part, and
is incorporated herein by reference. Capitalized terms used herein which are not
otherwise  defined in this Prospectus have the meanings  ascribed thereto in the
Mortgage.  Wherever  particular  provisions  of the  Mortgage  or terms  defined
therein are referred to, such  provisions or  definitions  are  incorporated  by
reference  as a part of the  statements  made  herein  and such  statements  are
qualified in their entirety by such reference. References to article and section
numbers  herein,  unless  otherwise  indicated,  are  references  to article and
section numbers of the Mortgage.


                                       6


<PAGE>


         The Mortgage  provides  that,  in addition to  Collateral  Trust Bonds,
additional debt securities may be issued  thereunder,  without  limitation as to
the aggregate principal amount. (See "Issuance of Additional Securities" below.)
The Bonds will be secured equally and ratably with all other  securities  issued
under the Mortgage.

Terms of Specific Series of the Bonds

         Reference  is  made  to  the  applicable  Prospectus  Supplement,  or a
supplement  thereto,  for a description of the following terms of the Bonds: (i)
the title of such Bonds;  (ii) the limit,  if any, upon the aggregate  principal
amount of such  Bonds;  (iii) the date or dates on which the  principal  of such
Bonds is payable; (iv) the rate or rates at which such Bonds will bear interest,
if any; the date or dates from which such  interest  will  accrue;  the dates on
which such interest will be payable ("Interest Payment Dates");  and the regular
record dates for the interest  payable on such Interest  Payment Dates;  (v) the
option, if any, of the Company to redeem such Bonds and the periods within which
or the dates on which,  the  prices at which and the terms and  conditions  upon
which,  such Bonds may be  redeemed,  in whole or in part,  upon the exercise of
such option;  (vi) the obligation,  if any, of the Company to redeem or purchase
Bonds  pursuant to any sinking fund or analogous  provisions or at the option of
the Holder (as hereinafter defined) and the periods within which or the dates on
which,  the prices at which and the terms and conditions upon which,  such Bonds
will be redeemed,  in whole or in part,  pursuant to such obligation;  (vii) the
denominations  in which such Bonds will be issuable;  (viii)  whether such Bonds
are to be  issued  in whole or in part in the form of one or more  global  Bonds
and, if so, the identity of the depositary  for such global Bonds;  and (ix) any
other terms of such Bonds not inconsistent with the provisions of the Mortgage.

Payment of Bonds; Transfers; Exchanges

         Except as may be provided in the applicable Prospectus Supplement, or a
supplement  thereto,  interest,  if any, on each Bond  payable on each  Interest
Payment  Date will be paid to the person in whose  name such Bond is  registered
(the registered  holder of any Bond being  hereinafter  called a "Holder") as of
the close of  business  on the regular  record  date  relating to such  Interest
Payment Date; provided,  however,  that interest payable at maturity (whether at
stated  maturity,  upon  redemption  or  acceleration  of maturity or otherwise,
hereinafter  "Maturity")  will be paid to the person to whom  principal is paid.
However,  if there has been a default in the  payment of  interest  on any Bond,
such  defaulted  interest  may be  payable  to the Holder of such Bond as of the
close of  business on a date  selected by the Trustee  which is not more than 15
days and not less than 10 days prior to the date  proposed  by the  Company  for
payment  of  such  defaulted   interest  or  in  any  other  lawful  manner  not
inconsistent with the requirements of any securities exchange on which such Bond
may be listed, if the Trustee deems such manner of payment practicable. (Section
307)

         Principal of and premium, if any, and interest on the Bonds at Maturity
will be payable upon  presentation  of the Bonds at the office of the Trustee in
Chicago,  Illinois or, at the option of the Holder,  at the principal  corporate
trust office of The First  National Bank of Chicago in New York,  New York.  The
transfer of Bonds may be  registered,  and the Bonds may be exchanged  for other
Bonds of the same series and tranche, of authorized  denominations of like tenor
and  aggregate  principal  amount,  at the office of The First  National Bank of
Chicago in New York, New York as Bond Registrar for the Bonds.  The Company will
not be required to issue, and no Bond Registrar will be required to register the
transfer of or to exchange (a) Collateral  Trust Bonds of any series  (including
the Bonds offered  hereby) during a period of 15 days prior to giving any notice
of  redemption  thereof or (b) any Bond  selected for  redemption in whole or in
part, except the unredeemed portion of any Bond being redeemed in part. (Section
305)

         The  Company  may  change  the place for  payment  or  registration  of
transfer  or exchange of the Bonds,  may appoint one or more  additional  Paying
Agents or Bond Registrars (including,  without limitation,  the Company) and may
remove any Paying Agent or Bond Registrar, all at its discretion. The applicable
Prospectus  Supplement or a supplement  thereto,  will identify any such changes
prior to the date of such Prospectus Supplement or supplement thereto.  (Section
602)

Redemption

         Any terms for the optional or mandatory redemption of the Bonds will be
set forth in a Prospectus  Supplement  or a supplement  thereto.  Except as will
otherwise  be provided  with  respect to Bonds  redeemable  at the option of the
Holder, redeemable Bonds will be redeemed only upon notice by mail not less than
30 nor more than 60 days prior to the date  fixed for  redemption  and,  if less
than all the Bonds of a series, or any tranche thereof, are to be redeemed,  the
particular  Bonds to be  redeemed  will be  selected  by such  method as will be
provided for any particular series, or in the absence of any such provision,  by
such method as the Bond Registrar deems fair and appropriate.  (Sections 503 and
504)

         Any notice of  redemption of Bonds,  at the option of the Company,  may
state that such redemption will be conditional  upon receipt by the Trustee,  on
or prior to the date fixed for such  redemption,  of money sufficient to pay the
principal of and premium,  if any, and interest,  if any, on such Bonds and that
if such  money has not been so  received,  such  notice  will be of no force and
effect and the Company will not be required to redeem such Bonds. (Section 504)

No Maintenance, Replacement or Sinking Funds

         While the  Mortgage  contains  provisions  for the  maintenance  of the
Mortgage  Property  (Section  601), it does not contain any  provisions  for any
maintenance,  replacement,  sinking  or  analogous  fund  and,  except as may be
provided in the applicable Prospectus Supplement, or a supplement thereto, there
will be no provisions for any such funds for the Bonds.

Security

         General.  Except as discussed below,  securities  (including the Bonds)
now or hereafter issued under the Mortgage will be secured primarily by:

                  (a) first mortgage bonds issued under the Company's  Indenture
         of Mortgage  and Deed of Trust,  dated as of August 1, 1940 (as amended
         and supplemented,  the "1940 Indenture"), to The First National Bank of
         Chicago,  as trustee (the "1940 Indenture  Trustee"),  and delivered to
         the Trustee under the Mortgage.  As discussed under "DESCRIPTION OF THE
         1940 INDENTURE - Security," the 1940 Indenture constitutes,  subject to
         certain  exceptions,  a first mortgage lien on substantially all of the
         properties  of the Company  except  properties  of Iowa Southern at the
         time of the IE-ISU merger;

                  (b)  first  mortgage   bonds  issued  under  Iowa   Southern's
         Indenture  or Deed of Trust,  dated as of  February 1, 1923 (as amended
         and supplemented,  the "ISU 1923  Indenture"),  with The Northern Trust
         Company  (The First  National  Bank of  Chicago,  successor)  (the "ISU
         Corporate  Trustee")  and  Harold  H.  Rockwell  (Richard  D.  Manella,
         successor) as trustees (the "ISU Indenture Trustees"), and delivered to
         the Trustee under the Mortgage;  as discussed under "DESCRIPTION OF THE
         ISU 1923  INDENTURE - Security,"  the ISU 1923  Indenture  constitutes,
         subject to certain  exceptions,  a first mortgage lien on substantially
         all of the properties  owned by Iowa Southern at the time of the IE-ISU
         merger  (which are now,  subsequent  to such merger,  properties of the
         Company); and

                  (c) the Lien of the Mortgage on the Company's  properties used
         in the  generation,  purchase,  transmission,  distribution  or sale of
         electric  energy by the Company,  or in the manufacture of manufactured
         gas,  or in the  purchase,  transportation,  distribution  or  sale  of
         manufactured  gas or natural  gas, or in the  generation,  manufacture,
         distribution  or sale of steam and hot  water,  which Lien is junior to
         the liens of the 1940 Indenture and the ISU 1923 Indenture.

(Granting Clause First)

         As  discussed  below  under  "Class "A"  Bonds,"  following a merger or


                                       8


<PAGE>


consolidation  of another  corporation  into the  Company,  or the  transfer  by
another  corporation  of property to the  Company,  the Company  could issue and
deliver to the Trustee bonds issued under an existing mortgage on the properties
of such other  corporation  in lieu of or in addition to bonds  issued under the
1940  Indenture  or the ISU  1923  Indenture.  In  such  event,  the  securities
(including the Bonds) issued under the Mortgage would be secured,  additionally,
by such bonds and by the Lien of the  Mortgage on the  properties  of such other
corporation, which would be junior to the liens of the existing mortgage of such
corporation,  the 1940 Indenture and the ISU 1923 Indenture.  The 1940 Indenture
and the ISU  1923  Indenture  and all  such  other  mortgages  are  hereinafter,
collectively,  called the "Class "A" Mortgages," and all bonds outstanding under
the Class "A"  Mortgages  are  hereinafter  collectively  called  the "Class "A"
Bonds." If and when no Class "A"  Mortgages  are in effect,  the  Mortgage  will
constitute a first mortgage lien on all property of the Company subject thereto.
(Sections 101 and 706)

         Class "A"  Bonds.  Any Class  "A"  Bonds  issued  after the date of the
Mortgage  (other than in  substitution  or exchange for  previously  outstanding
Class "A" Bonds) will be issued and delivered to, and registered in the name of,
the Trustee or its nominee and will be owned and held by the Trustee, subject to
the provisions of the Mortgage, for the benefit of the Holders of all securities
issued  under the Mortgage and  Outstanding  from time to time.  Class "A" Bonds
issued as the basis of  authentication  and  delivery  of  securities  under the
Mortgage (a) will mature on the same dates,  and in the same principal  amounts,
as such securities and (b) will contain, in addition to any mandatory redemption
provisions applicable to all Class "A" Bonds Outstanding under the related Class
"A" Mortgage,  mandatory  redemption  provisions  correlative  to provisions for
mandatory  redemption,  or for  redemption at the option of the Holder,  of such
securities.  Class "A" Bonds issued as the basis for authentication and delivery
of a series or tranche of  securities  under the Mortgage (x) may, but need not,
bear interest,  any such interest to be payable at the same times as interest on
the  securities  of such  series or tranche and (y) may,  but need not,  contain
provisions  for the  redemption  thereof at the option of the Company,  any such
redemption  to be made at a  redemption  price  or  prices  not  less  than  the
principal amount of such Class "A" Bonds.
(Sections 402 and 701)

         Any  payment by the Company of  principal  of or premium or interest on
the Class "A" Bonds held by the  Trustee  will be applied by the  Trustee to the
payment of any principal, premium or interest, as the case may be, in respect of
any  Mortgage  securities  which  is  then  due  and,  to  the  extent  of  such
application,  the  obligation  of the  Company  under the  Mortgage to make such
payment in respect of such securities  will be deemed  satisfied and discharged.
If,  at the time of any such  payment  of  principal  of Class "A"  Bonds,  such
payment  shall  exceed  the  amount  of  principal  then due in  respect  of the
securities,  the excess of such payment will be deemed to constitute Funded Cash
and  will be held by the  Trustee  as  part  of the  Mortgaged  Property,  to be
withdrawn,  used or applied as provided in the Mortgage.  If, at the time of any
such payment of premium or interest on Class "A" Bonds held by the Trustee, such
payment  shall  exceed the amount of premium or interest  then due in respect of
such securities,  the excess of such payments will be remitted to the Company at
its  request.  Any payment by the Company of principal of or premium or interest
on any  Mortgage  securities  authenticated  and  delivered  on the basis of the
deposit  with the Trustee of Class "A" Bonds (other than by  application  of the
proceeds  of a payment in respect of such Class "A" Bonds)  will,  to the extent
thereof,  be deemed to satisfy and discharge the  obligation of the Company,  if
any, to make a payment of principal, premium or interest, as the case may be, in
respect of such Class "A" Bonds which is then due. (Section 702; see "Withdrawal
of Cash" below.)

         The Trustee may not sell,  assign or  otherwise  transfer any Class "A"
Bonds held by the Trustee  except to a  successor  trustee  under the  Mortgage.
(Section 704) At the time any Mortgage securities of any series or tranche which
have been authenticated and delivered upon the basis of Class "A" Bonds cease to
be  Outstanding  (other than a result of the  application of the proceeds of the
payment or redemption of such Class "A" Bonds),  the Trustee shall surrender to,
or upon the order of, the  Company an equal  principal  amount of such Class "A"
Bonds having the same Stated  Maturity and  mandatory  redemption  provisions as
such securities.  (Section 703)

         At the date of this  Prospectus,  the only Class "A"  Mortgages are the
1940  Indenture and the ISU 1923 Indenture and the only Class "A" Bonds issuable
are first mortgage bonds issuable thereunder.  The Mortgage provides that in the
event  of the  merger  or  consolidation  of  another  company  with or into the
Company,  an existing  mortgage  constituting a lien on properties of such other
company prior to the Lien of the Mortgage may be designated by the Company as an
additional Class "A" Mortgage. Any bonds thereafter issued under such additional
mortgage  would be Class "A" Bonds and (other than in  substitution  or exchange
for previously  Outstanding Class "A" Bonds) could be issued only to provide the
basis for the  authentication  and delivery of  securities  under the  Mortgage.
(Section 706)


                                       9


<PAGE>


         When no bonds are  Outstanding  under a Class "A"  Mortgage  except for
Class "A" Bonds held by the  Trustee,  then,  at the  request of the Company and
subject to satisfaction of certain  conditions,  the Trustee will surrender such
Class "A" Bonds for  cancellation  and the related  Class "A"  Mortgage  will be
satisfied and discharged;  whereupon, the lien of such Class "A" Mortgage on the
property  owned by the Company  will cease to exist and the Lien of the Mortgage
will become a first mortgage lien on such property,  subject to Permitted Liens.
(Section 707)

         So long as any  securities  are  Outstanding  under the  Mortgage,  the
Company will not (a) issue any additional  Class "A" Bonds except (i) to replace
any  mutilated,  destroyed,  lost or stolen  securities of the same series or to
effect  exchanges and transfers of such securities or (ii) to the Trustee as the
basis for the  authentication  and delivery of  securities or (b) subject to the
lien of any Class "A" Mortgage any property which is excepted and excluded from,
or not included in or subject to, the lien of such Class "A" Mortgage.  (Section
610) First mortgage bonds may be issued under the 1940 Indenture on the basis of
property  additions,  retirements  of bonds  previously  issued  under  the 1940
Indenture and cash deposited with the 1940 Indenture Trustee.  (See "DESCRIPTION
OF THE 1940 INDENTURE - Issuance of Additional Bonds.") First mortgage bonds may
be issued  under the ISU 1923  Indenture  on the  basis of  property  additions,
retirements  of bonds  previously  issued under the ISU 1923  Indenture and cash
deposited  with the ISU Corporate  Trustee.  (See  "DESCRIPTION  OF THE ISU 1923
INDENTURE - Issuance of Additional Bonds.")

         Lien of the Mortgage. At the date of this Prospectus, substantially all
of the Company's property subject to the Lien of the Mortgage is also subject to
the  prior  lien of the 1940  Indenture  or the ISU 1923  Indenture.  Any  Bonds
offered  hereby  will have the  benefit of the first  mortgage  lien of the 1940
Indenture and the ISU 1923  Indenture on such  property,  and the benefit of the
prior lien of any additional Class "A" Mortgage on any property subject thereto,
to the extent of the aggregate  principal amount of Class "A" Bonds issued under
the respective Class "A" Mortgage and held by the Trustee.

         The Lien of the  Mortgage is subject to Permitted  Liens which  include
tax liens and other  governmental  charges which are not delinquent or which can
thereafter be paid without  penalty or which are being  contested,  construction
and materialmen's  liens,  certain judgment liens,  easements,  reservations and
rights of others (including  governmental entities) in, and defects of title in,
certain  property of the  Company,  certain  leasehold  interests,  liens on the
Company's pollution control and sewage and solid waste disposal facilities which
were previously  financed with industrial  development revenue bonds and certain
other liens and encumbrances. (Granting Clauses and Section 101)

         There are excepted from the Lien of the  Mortgage,  among other things,
cash and securities not paid,  deposited or held under the Mortgage;  contracts,
leases and other  agreements of all kinds,  contract  rights,  bills,  notes and
other instruments,  accounts receivable, claims, judgments, certain intellectual
property  rights  and  other  general  intangibles;  automobiles,  aircraft  and
vessels;  all  goods,  wares,  merchandise,   equipment,   spare  parts,  tools,
materials,  supplies and fuel held for sale or lease in the  ordinary  course of
business or for use or consumption in, or in the operation of, any properties of
or for the  benefit of the  Company;  nuclear  fuel;  computers,  machinery  and
equipment used exclusively for corporate  administrative  or clerical  purposes;
all gas, oil,  minerals and timber,  and rights thereto;  electric energy,  gas,
steam,  water and other  products  generated,  produced or  purchased;  property
installed  on the  premises of  customers  of the Company and designed to aid in
conservation  or efficient  use of energy;  leasehold  interests  and  leasehold
improvements  of the Company;  and all property which is located  outside of the
State of Iowa and is neither  specifically  described in the Granting Clauses of
the Mortgage nor specifically  subjected or required to be subjected to the Lien
of the Mortgage by any provision thereof. (Granting Clauses)

         Without  the  consent of the  Holders,  the Company and the Trustee may
enter  into  supplemental  indentures  to  subject  to the Lien of the  Mortgage
additional  property  (including property which would otherwise be excepted from
such Lien).  (Section 1401) Such property,  so long as the same would  otherwise
constitute Property Additions, would thereupon constitute Property Additions and
be available as a basis for the issuance of securities under the Mortgage.  (See
"Issuance of Additional Securities" below.) Property Additions generally include
any unit or element of property  which is owned by the Company and is subject to
the Lien of the Mortgage  except (i) any property,  the cost of  acquisition  or
construction of which is property  chargeable to an operating expense account of
the  Company  and (ii)  goodwill,  going  concern  value  rights and  intangible
property,  unless  the cost  thereof  is  included  in the cost of such  unit or
element  of  property  and no  separate  consideration  was paid or  apportioned
therefor,  in which case  Property  Additions may include such  goodwill,  going
concern rights and intangible property. (Section 103)


                                       10


<PAGE>


         The Mortgage contains  provisions  subjecting  after-acquired  property
(other than Excepted Property) to the Lien thereof. These provisions are limited
in the case of  consolidation  or  merger  or sale of  substantially  all of the
Company's assets. In the event of consolidation or merger or the transfer of all
of the Mortgaged Property as or substantially as an entirety,  the Mortgage will
not be required to be a lien upon any of the properties then owned or thereafter
acquired  by the  successor  corporation  except  properties  acquired  from the
Company  in or as a result  of such  transaction  and  properties  which  are an
integral  part of,  or  essential  to the use or  operation  of,  any  Mortgaged
Property,  and  renewals,  replacements  and  substitutions  of or for any  part
thereof. (Article Thirteen; see "Consolidation,  Merger, Conveyance, Transfer or
Lease" below.) In addition,  after-acquired  property may be subject to vendors'
liens,  purchase  money  mortgages  and  other  liens  thereon  at the  time  of
acquisition thereof, including the lien of any Class "A" Mortgage.

         The Mortgage  provides that the Trustee will have a lien,  prior to the
lien on behalf of the holders of  securities  issued  under the  Mortgage,  upon
Mortgaged Property, for the payment of its reasonable  compensation and expenses
and for indemnity against certain liabilities. (Section 1107)

Issuance of Additional Securities

         The maximum  principal  amount of securities  which may be issued under
the Mortgage is unlimited.  (Section 301) Under the Mortgage,  securities of any
series  may be issued  from time to time on the  basis of,  and in an  aggregate
principal amount not exceeding:

         (1)      the aggregate  principal  amount of Class "A" Bonds issued and
delivered to the Trustee for such purpose;

         (2)      75% of the Cost or fair value  (whichever is less) of Property
Additions  (as  described  below)  which  do  not  constitute   Funded  Property
(generally, Funded Property includes Property Additions which have been made, or
deemed to have  been  made,  the basis of the  authentication  and  delivery  of
securities,  the release of Mortgaged  Property from the Lien of the Mortgage or
cash withdrawals,  or which have been substituted for retired  property),  after
certain  deductions and  additions,  primarily  including  adjustments to offset
property retirements;

         (3)      the aggregate  principal amount of Retired  Securities  (which
consist of securities no longer  outstanding  under the Mortgage  which have not
been used for certain other  purposes under the Mortgage and which are not to be
paid,  redeemed,  purchased or otherwise  retired by the application  thereto of
Funded Cash) or Retired Prior Lien Bonds; and

         (4)      the amount of cash deposited with the Trustee.

(Article Four)

         The Company is not required to satisfy a net earnings requirement prior
to the issuance of securities under the Mortgage.

         Unless otherwise provided in the applicable Prospectus  Supplement,  or
supplement  thereto,  the Company will issue the Bonds on the basis of Class "A"
Bonds issued under the 1940 Indenture. (See "DESCRIPTION OF THE 1940 INDENTURE -
Issuance of Additional  Bonds" for a  description  of the  requirements  for the
issuance of bonds under the 1940  Indenture,  which  requirements  are generally
more restrictive than those for the issuance of securities under the Mortgage.)

Release of Property

         Unless an Event of Default  (hereinafter  defined)  shall have occurred
and be  continuing,  the  Company  may obtain the  release  from the Lien of the


                                       11


<PAGE>


Mortgage  of any  Funded  Property,  except for cash held by the  Trustee,  upon
delivery to the Trustee of cash equal in amount to the amount,  if any, that the
Cost of the  property  to be  released  (or,  if less,  the  fair  value of such
property at the time it became Funded Property) exceeds the aggregate of:

                  (1)       the   principal    amount,    subject   to   certain
         limitations,  of obligations  secured by purchase money  mortgages upon
         the property to be released delivered to the Trustee;

                  (2)       the  Cost or  fair  value  (whichever  is  less)  of
         certified  Property  Additions not  constituting  Funded Property after
         certain deductions and additions,  primarily  including  adjustments to
         offset property  retirements  (except that such adjustments need not be
         made if such Property Additions were acquired or made within the 90-day
         period preceding the request for such release);

                  (3)       an  amount  equal  to  133-1/3%  of  the   aggregate
         principal  amount of securities  the Company would be entitled to issue
         on the basis of Retired  Securities  or Retired  Prior Lien Bonds (with
         such entitlement being waived by operation of such release);

                  (4)       the amount of cash deposited  with, or the principal
         amount of  obligations  secured by purchase  money  mortgages  upon the
         property  released and  delivered  to, the Trustee or other holder of a
         lien prior to the Lien of the Mortgage;

                  (5)       an  amount  equal  to  133-1/3%  of  the   aggregate
         principal  amount of  securities  Outstanding  under the  Mortgage  and
         delivered to the Trustee  (with such  Securities  to be canceled by the
         Trustee); and

                  (6)       any  taxes  and  expenses  incidental  to any  sale,
         exchange,  dedication  or  other  disposition  of  the  property  to be
         released.

(Section 803)

         Unless an Event of  Default  shall  have  occurred  and be  continuing,
property which is not Funded Property may generally be released from the Lien of
the Mortgage without depositing any cash or property with the Trustee as long as
(a) the  aggregate  amount  of Cost or fair  value  (whichever  is  less) of all
Property  Additions  which do not  constitute  Funded  Property  (excluding  the
property to be released)  after  certain  deductions  and  additions,  primarily
including adjustments to offset property  retirements,  is not less than zero or
(b) the Cost or fair value  (whichever  is less) of property to be released does
not exceed the aggregate amount of the Cost or fair value (whichever is less) of
Property  Additions  acquired or made  within the 90-day  period  preceding  the
release. (Section 804)

         The Mortgage provides simplified procedures for the release of property
which has been released from the lien of Class "A" Mortgages,  minor  properties
and property taken by eminent domain,  and provides for  dispositions of certain
obsolete  property and grants or surrender of certain rights without any release
or consent by the Trustee.

         If any  property  released  from the Lien of Mortgage  continues  to be
owned by the Company after such release,  the Mortgage will not become a lien on
any   improvement,   extension  or  addition  to  such   property  or  renewals,
replacements  or  substitutions  of or for any part or  parts of such  property.
(Article Eight)

Withdrawal of Cash

         Subject to certain  limitations,  unless an Event of Default shall have
occurred and be continuing, cash held by the Trustee may (1) be withdrawn by the
Company  (a) to the  extent  of the Cost or fair  value  (whichever  is less) of
Property  Additions not constituting  Funded Property,  after certain deductions
and additions,  primarily including  adjustments to offset retirements or (b) in
an amount equal to 133-1/3% of the aggregate principal amount of securities that
the  Company  would be  entitled  to issue  under the  Mortgage  on the basis of
Retired  Securities  or Retired Prior Lien Bonds (with the  entitlement  to such
issuance being waived by operation of such withdrawal) or (c) in an amount equal
to 133-1/3% of the  aggregate  principal  amount of any  securities  Outstanding
under the Mortgage  and issued under the Mortgage and  delivered to the Trustee,
or (2) upon the  request  of the  Company,  be applied  to (a) the  purchase  of


                                       12


<PAGE>


securities  issued under the Mortgage (at prices not  exceeding  133-1/3% of the
principal amount thereof) or (b) the redemption or payment at Stated Maturity of
securities  issued  under the  Mortgage  (with any  securities  received  by the
Trustee  pursuant to these  provisions  being canceled by the Trustee)  (Section
806); provided,  however,  that cash deposited with the Trustee as the basis for
the  authentication  and delivery of securities,  as well as cash representing a
payment of  principal  of Class "A" Bonds,  may only be  withdrawn  in an amount
equal to the  aggregate  principal  amount of  securities  the Company  would be
entitled to issue under the Mortgage on any basis (with the  entitlement to such
issuance being waived by operation of such withdrawal), or may, upon the request
of the Company,  be applied to the purchase  redemption or payment of securities
issued  under the  Mortgage  at prices  not  exceeding,  in the  aggregate,  the
principal amount thereof. (Sections 405 and 702)

Consolidation, Merger, Conveyance, Transfer or Lease

         The  Company  may  not  consolidate   with  or  merge  into  any  other
corporation  or  convey,   transfer  or  lease  the  Mortgaged  Property  as  or
substantially  as an entirety to any Person  unless (a) such  transaction  is on
such terms as will fully preserve in all material respects the Lien and security
of the Mortgage and the rights and powers of the Trustee and the Holders and (b)
the corporation formed by such consolidation or into which the Company is merged
or the Person which acquires by conveyance or other  transfer,  or which leases,
the  Mortgaged  Property as or  substantially  as an  entirety is a  corporation
organized and existing under the laws of the United States of America, any State
or Territory thereof or the District of Columbia,  and such corporation executes
and  delivers  to the  Trustee  a  supplemental  indenture,  which  contains  an
assumption by such corporation of the Company's  obligations  under the Mortgage
and  which  contains  a  grant,  conveyance,   transfer  and  mortgage  by  such
corporation  confirming  the Lien of the Mortgage on the Mortgaged  Property and
subjecting  to such Lien all property  thereafter  acquired by such  corporation
which shall constitute an integral part, or be essential to the use or operation
of, any Mortgage  Property or a renewal,  replacement or  substitution of or for
any part thereof. (Section 1301)

Modification of the Mortgage

         Without  the  consent of any  Holders,  the Company and the Trustee may
enter into one or more supplemental  indentures for certain purposes,  including
any of the following:

                  (a)       to evidence the  succession of another Person to the
         Company and the  assumption  by any such  successor of the covenants of
         the Company in the Mortgage and in the securities; or

                  (b)       to add one or more covenants of the Company or other
         provisions  for the  benefit of all  Holders or for the  benefit of the
         Holders  of,  or to remain  in  effect  only so long as there  shall be
         outstanding,  securities  issued  under  the  Mortgage  of one or  more
         specified series, or one or more tranches thereof,  or to surrender any
         right or power conferred upon the Company by the Mortgage; or

                  (c)       to  correct  or  amplify  the   description  of  any
         property at any time subject to the Lien of the Mortgage, or to subject
         to the Lien of the Mortgage additional property; or

                  (d)       to change or eliminate any provision of the Mortgage
         or to add any new  provision to the  Mortgage,  provided  that, if such
         change,  elimination or addition adversely affects the interests of the
         Holders of the  securities  of any  series or  tranche in any  material
         respect,  such change,  elimination  or addition will become  effective
         with  respect to such  series or tranche  only when no security of such
         series or tranche remains Outstanding under the Mortgage; or

                  (e)       to establish the form or terms of the  securities of
         any series or tranche as permitted by the Mortgage; or

                  (f)       to cure any ambiguity,  to correct or supplement any
         provision therein which may be defective or inconsistent with any other
         provision  therein,  or to comply with the rules or  regulations of any
         national  securities  exchange  on which any of the  securities  issued
         under the Mortgage may be listed, or to change,  alter, modify, vary or
         eliminate any of the provisions  thereof or to add other  provisions to
         the   Mortgage,   so   long  as  such   other   changes,   alterations,
         modifications,  variations,  eliminations or additions do not adversely
         affect the  interests  of the  Holders of  securities  of any series or
         tranche in any material  respect,  unless they are expressly  stated to
         become effective only as to securities which are not then Outstanding.


                                       13


<PAGE>


         Without  limiting  the  generality  of  the  foregoing,  if  the  Trust
Indenture Act of 1939, as amended (the "Trust  Indenture Act"), is amended after
the date of the Mortgage in such a way as to require  changes to the Mortgage or
the  incorporation  therein of additional  provisions or so as to permit changes
to, or the elimination of,  provisions  which, at the date of the Mortgage or at
any time thereafter, were required by the Trust Indenture Act to be contained in
the  Mortgage,  the  Company  and the  Trustee  may,  without the consent of any
Holders,  enter into one or more  supplemental  indentures to evidence or effect
such amendments. (Section 1401)

         For most  purposes not described  above,  the consent of the Holders of
not less than a majority in aggregate  principal amount of the securities of all
affected series then Outstanding  under the Mortgage is required for the purpose
of amending  or  modifying  the  Mortgage  pursuant to one or more  supplemental
indentures;  provided,  however,  that no such  amendment or  modification  may,
without the consent of each Holder of the Outstanding  securities of each series
or tranche  directly  affected  thereby,  (a) change the Stated  Maturity of the
principal  of, or any  installment  of principal of or interest on, any security
issued under the Mortgage, or reduce the principal amount thereof or the rate of
interest  thereon  (or the amount of any  installment  of  interest  thereon) or
change the method of  calculating  such rate or reduce any premium  payable upon
the  redemption  thereof,  or  impair  the  right  to  institute  suit  for  the
enforcement of any such payment on or after the maturity thereof, (b) permit the
creation of any lien ranking  prior to the Lien of the Mortgage  with respect to
all or substantially all of the Mortgaged  Property or terminate the Lien of the
Mortgage,  or (c) reduce the percentage in principal  amount of the  Outstanding
securities  of such  series or  tranche,  the consent of the Holders of which is
required for any such supplemental  indenture,  or the consent of the Holders of
which is  required  for any  waiver  of  compliance  with any  provision  of the
Mortgage  or of any  default  thereunder  and its  consequences,  or reduce  the
requirements  for quorum or voting.  A supplemental  indenture  which changes or
eliminates  any covenant or other  provision of the Mortgage which has expressly
been included solely for the benefit of the Holders of, or which is to remain in
effect  only so long as there  shall be  Outstanding  securities  of one or more
specified series, or one or more tranches thereof, or modifies the rights of the
Holders of securities  such series or tranches with respect to such covenants or
other  provision,  will not be deemed to affect the rights under the Mortgage of
Holders of the securities of any other series or tranche. (Section 1402)

Waiver

         The Holders of at least a majority in aggregate principal amount of all
affected  Outstanding  securities  issued  under  the  Mortgage  may  waive  the
Company's obligations to comply with certain covenants of the Mortgage, provided
that such waiver  occurs before the time such  compliance is required.  (Section
609)

Events of Default

         Each of the following events  constitutes an Event of Default under the
Mortgage:

                  (1)       failure to pay interest on any security issued under
         the Mortgage within 90 days after the same becomes due;

                  (2)       failure to pay principal or premium,  if any, on any
         security issued under the Mortgage within three business days after its
         due date;

                  (3)       failure  to  perform  or breach of any  covenant  or
         warranty of the Company in the  Mortgage  (other than as referred to in
         (1) or (2) above) for a period of 90 days after there has been given to
         the  Company by the  Trustee,  or to the Company and the Trustee by the
         Holders of at least 30% in principal  amount of Outstanding  securities
         issued under the Mortgage,  a written notice specifying such default or
         breach and  requiring it to be remedied and stating that such notice is
         a "Notice of  Default,"  unless the  Trustee,  or the  Trustee  and the
         Holders of a principal amount of securities not less than the principal
         amount of securities the Holders of which gave such notice, as the case
         may be,  agree in writing to an  extension  of such period prior to its
         expiration;  provided,  however,  that the Trustee,  or the Trustee and
         such  Holders,  as the case may be, will be deemed to have agreed to an
         extension of such period if corrective action has been initiated by the
         Company within such period and is being diligently pursued;


                                       14


<PAGE>


                  (4)       certain   events    relating   to    reorganization,
         bankruptcy and insolvency of the Company and  appointment of a receiver
         or trustee for its property; and

                  (5)       the  occurrence  of a matured event of default under
         any Class "A"  Mortgage;  provided  that the waiver or cure of any such
         event of default and the rescission  and annulment of the  consequences
         thereof shall constitute a waiver of the corresponding Event of Default
         under the Mortgage and a rescission  and annulment of the  consequences
         thereof.

(Section 1001)

         The Trust  Indenture Act  currently  requires that the Company give the
Trustee,  not less often than  annually,  a brief  statement as to the Company's
compliance with the conditions and covenants under the Mortgage.

Remedies

         If an Event of Default  occurs and is  continuing,  then the Trustee or
the Holders of not less than a majority in principal  amount of securities  then
Outstanding  under the  Mortgage  may  declare the  principal  amount (or if the
securities are Discount Securities,  such portion of the principal amount as may
be provided for such Discount  Securities pursuant to the terms of the Mortgage)
of all of the securities  Outstanding  under the Mortgage together with premium,
if any, and interest accrued, if any, thereon to be immediately due and payable.
At any time  after such  declaration  of the  maturity  of the  securities  then
Outstanding,  but before the sale of any of the Mortgaged  Property and before a
judgment or decree for payment of money shall have been  obtained by the Trustee
as provided in the Mortgage,  the Event or Events of Default giving rise to such
declaration  of  maturity  will,  without  further  act,  be deemed to have been
waived,  and such declaration and its consequences will, without further act, be
deemed to have been rescinded and annulled, if

         (a)      the  Company  has paid or  deposited  with the  Trustee  a sum
sufficient to pay

                  (1)      all overdue interest,  if any, on all securities then
         Outstanding under the Mortgage;

                  (2)      the  principal  of  and  premium,   if  any,  on  any
         securities  then  Outstanding  under the Mortgage which have become due
         otherwise than by such declaration of acceleration and interest thereon
         at the rate or rates prescribed therefor in such securities; and

                  (3)      all amounts due to the  Trustee as  compensation  and
         reimbursement as provided in the Mortgage; and

         (b)      any  other   Event  or  Events  of  Default   other  than  the
non-payment of the principal of securities which shall have become due solely by
such declaration of acceleration, shall have been cured or waived as provided in
the Mortgage.

(Sections 1002 and 1017)

         The Mortgage  provides  that,  under certain  circumstances  and to the
extent  permitted by law, if an Event of Default occurs and is  continuing,  the
Trustee has the power to take  possession  of, and to hold,  operate and manage,
the Mortgaged  Property,  or with or without entry, sell the Mortgaged Property.
If the  Mortgaged  Property  is sold,  whether  by the  Trustee or  pursuant  to
judicial  proceedings,  the principal of the  securities  Outstanding  under the
Mortgage,  if not previously  due, will become  immediately  due,  together with
premium,  if any,  and any accrued  interest  (including  interest  upon overdue
installments  of  interest  at the same rates  respectively  as were born by the
respective securities on which installments of interest were overdue). (Sections
1003, 1004 and 1005)

         If an Event of  Default  occurs  and is  continuing,  the  Holders of a
majority  in  principal  amount of the  securities  then  Outstanding  under the


                                       15

Mortgage will have the right to direct the time,  method and place of conducting
any proceedings for any remedy  available to the Trustee or exercising any trust
or power  conferred on the Trustee,  provided that (a) such  direction  does not
conflict  with any rule of law or with the  Mortgage,  and could not involve the
Trustee in personal liability in circumstances where indemnity would not, in the
Trustee's  sole  discretion,  be adequate and (b) the Trustee may take any other
action  deemed  proper  by the  Trustee  which  is not  inconsistent  with  such
discretion. (Section 1016)

         The  Mortgage  provides  that no Holder of any  security  will have any
right to institute any  proceeding,  judicial or otherwise,  with respect to the
Mortgage for the  appointment  of a receiver or for any other remedy  thereunder
unless (a) such Holder has previously  given to the Trustee  written notice of a
continuing  Event of  Default;  (b) the  Holders of not less than a majority  in
aggregate principal amount of the securities then Outstanding under the Mortgage
have made written request to the Trustee to institute  proceedings in respect of
such Event of Default and have offered the Trustee reasonable  indemnity against
costs and  liabilities  incurred in  complying  with such  request;  and (c) the
Trustee has refused, or for sixty days after receipt of such Notice, the Trustee
has failed, to institute any such proceeding and no direction  inconsistent with
such  request  has been  given to the  Trustee by the  Holders of a majority  in
aggregate  principal amount of securities then  Outstanding  under the Mortgage.
Furthermore,  no Holder will be entitled to institute  any such action if and to
the extent that such action would  disturb or prejudice  the rights of the other
Holders. (Section 1011)

         Notwithstanding  that the right of a Holder to  institute a  proceeding
with respect to the Mortgage is subject to certain  conditions  precedent,  each
Holder of a security  has the right,  which is absolute  and  unconditional,  to
receive payment of the principal of and premium, if any, and interest (including
interest  upon  overdue  interest),  if any,  on such  security  when due and to
institute suit for the enforcement of any such payment,  and such rights may not
be impaired without the consent of such Holder. (Section 1012)

         The Mortgage  obligates  the Trustee to give the Holders  notice of any
default under the Mortgage to the extent  required by the Trust  Indenture  Act,
unless such default shall have been cured or waived,  except that no such notice
to Holders of a default of the character described in paragraph (3) under "Event
of Default" shall be given until at least 60 days after the occurrence  thereof.
(Section 1102) The Trust Indenture Act currently permits the Trustee to withhold
notices of default (except for certain payment  defaults) if the Trustee in good
faith  determines  the  withholding of such notice to be in the interests of the
Holders.

         As a  condition  precedent  to certain  actions  by the  Trustee in the
enforcement of the Lien of Mortgage and  institution of action on the securities
Outstanding  under the  Mortgage,  the Trustee may  require  adequate  indemnity
against costs, expenses and liabilities to be incurred in connection therewith.
(Sections 1011 and 1101)

         In addition to every other right and remedy  provided in the  Mortgage,
the Trustee may  exercise  any right or remedy  available  to the Trustee in its
capacity  as owner and Holder of Class "A" Bonds  which  arises as a result of a
default or matured event of default under any Class "A" Mortgage, whether or not
an Event of Default under the Mortgage has occurred and is continuing.  (Section
1020)

Defeasance

         Upon  request of the  Company,  any  securities  Outstanding  under the
Mortgage, or any portion of the principal amount thereof, will be deemed to have
been paid for  purposes  of the  Mortgage,  and the entire  indebtedness  of the
Company in respect thereof will be deemed to have been satisfied and discharged,
if there has been  irrevocably  deposited  with the Trustee or any Paying  Agent
(other  than the  Company),  in trust:  (a) money in the  amount  which  will be
sufficient,  or (b) Eligible  Obligations  (as  described  below),  which do not
contain provisions  permitting the redemption or other prepayment thereof at the
option of the issuer  thereof,  the  principal of and the interest on which when
due,  without any regard to  reinvestment  thereof,  will provide  monies which,
together with the money, if any, deposited with or held by the Trustee,  will be
sufficient, or (c) a combination of (a) and (b) which will be sufficient, to pay
when due the principal of and premium, if any, and interest,  if any, due and to
become  due on such  securities  or  portions  thereof.  (Section  901) For this
purpose,  Eligible  Obligations  include direct  obligations  of, or obligations
unconditionally  guaranteed  by, the United  States of America,  entitled to the
benefit of the full  faith and  credit  thereof,  and  certificates,  depositary
receipts or other instruments which evidence a direct ownership interest in such
obligations  or in any specific  interest or  principal  payments due in respect
thereof.


                                       16


<PAGE>


         While the Company knows of no legal  precedent on point, it is possible
that, for federal income tax purposes, any deposit contemplated in the preceding
paragraph could be treated as a taxable  exchange of the related  securities for
an issue of  obligations  of the  trust  or a  direct  interest  in the cash and
securities  held in the trust. In that case,  Holders of such  securities  would
recognize  gain or loss as if the trust  obligations  or the cash or  securities
deposited,  as the case may be, had actually  been  received by them in exchange
for their securities.  In addition, such Holders thereafter would be required to
recognize for federal income tax purposes a share of the income, gain or loss of
the trust.  The amount so required to be recognized  could be different from the
amount  that would be  recognized  in the absence of such  deposit.  Prospective
investors  are  urged to  consult  their  own tax  advisors  as to the  specific
consequences to them of any such deposit.

Resignation of the Trustee

         The Trustee may resign at any time by giving  written notice thereof to
the Company or may be removed at any time by act of the Holders of a majority in
principal amount of securities then Outstanding delivered to the Trustee and the
Company.  No  resignation  or removal of the  Trustee  and no  appointment  of a
successor trustee will become effective until the acceptance of appointment by a
successor  trustee in accordance with the requirements of the Mortgage.  So long
as no Event of Default or event which,  after notice or lapse of time,  or both,
would become an Event of Default has occurred and is continuing,  if the Company
has delivered to the Trustee a resolution of its Board of Directors appointing a
successor trustee and such successor has accepted such appointment in accordance
with the terms of the Mortgage,  the Trustee will be deemed to have resigned and
the  successor  will be deemed to have been  appointed as trustee in  accordance
with the Mortgage. (Section 1110)

More Restrictive Provisions of Class "A" Mortgages

         The Mortgage is less  restrictive  upon the Company in certain respects
than is either the 1940 Indenture or the ISU 1923  Indenture,  but the Class "A"
Bonds issued under either of those  indentures and delivered to the Trustee will
be entitled to the benefits of more  restrictive  provisions of those indentures
(see  "DESCRIPTION  OF THE  1940  INDENTURE"  and  "DESCRIPTION  OF THE ISU 1923
INDENTURE" below). However,  pursuant to the Mortgage, the Trustee, as holder of
the  Class "A"  Bonds,  will  vote  such  Class  "A"  Bonds in favor of  certain
amendments  to the 1940  Indenture  and ISU 1923  Indenture.  (Section  705; see
"Voting of Class "A" Bonds" under each of  "DESCRIPTION  OF THE 1940  INDENTURE"
and "DESCRIPTION OF THE ISU 1923 INDENTURE" below).

Relationship with the Trustee

         The Trustee or an affiliate  provides  general banking  services to the
Company  including (i) acting as a depositary for certain Company funds and (ii)
issuing a $15,000,000  line of credit to the Company.  As of March 31, 1997, the
line of credit was being used to support  commercial  paper.  Additionally,  the
Trustee has a  $45,000,000  credit  agreement  with the lessor of the  Company's
nuclear fuel supporting the Company's nuclear fuel lease.

         The Trustee is also the 1940 Indenture Trustee,  the ISU 1923 Corporate
Trustee and the Subordinated Indenture Trustee (each as defined below). As such,
the  Trustee  would  have a  conflicting  interest  for  purposes  of the  Trust
Indenture Act if an Event of Default were to occur under the 1940 Indenture, the
ISU 1923 Indenture or the Subordinated  Indenture. In any such case, the Trustee
may be required to  eliminate  such  conflicting  interest by  resigning  as the
Trustee,  the 1940  Indenture  Trustee,  the ISU 1923  Corporate  Trustee or the
Subordinated  Indenture  Trustee.  There  are  other  instances  under the Trust
Indenture Act which would  require the  resignation  of the Trustee,  such as an
affiliate  of the  Trustee  acting as  underwriter  with  respect  to any of the
Securities.

         The  summaries of the 1940  Indenture set forth below do not purport to
be complete and are subject to the detailed provisions of the 1940 Indenture,  a
copy of which was previously filed with the Commission,  is listed as an exhibit
to the  Registration  Statement  of  which  this  Prospectus  is a part,  and is
incorporated  herein by reference.  Capitalized terms used in this section which
are not otherwise defined in this Prospectus shall have the meanings ascribed to
them in the 1940 Indenture.  Wherever particular  provisions or terms defined in
the 1940 Indenture are referred to herein,  such  provisions or definitions  are
incorporated  by  reference  as part of the  statements  made  herein,  and such
statements  are  qualified in their  entirety by such  reference.  References to
article and section numbers in this section,  unless  otherwise  indicated,  are

Security

         The  1940  Indenture  constitutes  a  direct  first  mortgage  lien  on
substantially  all of the property  and  franchises  of the Company  (other than
expressly  excepted property and other than properties owned by Iowa Southern at
the time of the IE-ISU merger on December 31,  1993),  subject only to permitted
encumbrances and liens.  Substantially  all property and franchises  (other than
expressly  excepted  property)  hereafter  acquired by the  Company  will become
subject to the lien of the 1940  Indenture,  subject only to permitted liens and
encumbrances  and liens and  encumbrances,  if any,  existing  or placed on such
after-acquired property at the time of acquisition thereof. The lien of the 1940
Indenture  on the  property  owned by Iowa  Southern  at the time of the  IE-ISU
merger, and extensions and additions appurtenant to such property, are junior to
the lien of the ISU 1923 Indenture.

         The 1940 Indenture excepts from the lien thereof all cash,  securities,
contracts,  and bills,  notes and accounts  receivable  acquired in the ordinary
course of business which are not  specifically  pledged under the 1940 Indenture
and all tangible  personal  property  purchased or held for sale in the ordinary
course of business or consumable in the operation of the plants or system of the
Company, automobiles, buses, trucks and similar vehicles. (Granting Clauses)

         Any bonds issued under the 1940 Indenture as the basis for the issuance
of Bonds under the Mortgage  will be secured  equally and ratably with the bonds
of all other series then outstanding under the 1940 Indenture.

Effect of the IE-ISU Merger on the 1940 Indenture

         The merger of IE and ISU did not impair the lien of the 1940  Indenture
or any of the rights or powers of the 1940 Indenture  Trustee or the bondholders
under the 1940 Indenture.  (Section 133) Subsequent to that merger,  the Company
became the successor to IE under the 1940 Indenture.

Issuance of Additional Bonds

         The 1940 Indenture does not fix an overall  limitation on the aggregate
principal  amount of the bonds of all series  that may be issued or  outstanding
thereunder. (Section 3) Generally, additional bonds of any series may be issued,
subject to the provisions of the 1940 Indenture, in a principal amount equal to:

                  (a)      60% of Net Bondable Additions not previously utilized
         under the 1940 Indenture  resulting  from the  acquisition by purchase,
         construction or otherwise of Property Additions (Article IV);

                  (b)      the   principal    amount   of   bonds,    previously
         authenticated under the 1940 Indenture,  which have been retired or for
         the retirement of which the 1940 Indenture  Trustee holds the necessary
         funds,  other than bonds redeemed through the operation of cash sinking
         funds and other than retired bonds used to satisfy the  maintenance and
         renewal provisions of the 1940 Indenture (Article VI); or

                  (c)      the amount of cash  deposited with the 1940 Indenture
         Trustee as the basis for the issuance of such bonds,  which cash may be
         applied to the  retirement  of bonds or may be withdrawn in lieu of the
         authentication   of  an  equal  principal  amount  of  bonds  to  whose
         authentication  and  delivery the Company  would be entitled  under the
         provisions referred to in clauses (a) and (b). (Article V)


                                       18


<PAGE>


         No such bonds in any event may be issued under (a) or (c), or under (b)
if the bonds to be issued bear a higher rate of interest  than that borne by the
bonds  retired  or being  retired  (except in case such  bonds  mature  within 2
years),  unless (i) the Net  Earnings  of the  Company  for a 12 months'  period
within the  immediately  preceding  15 months'  period  shall have been at least
equal to two times the aggregate  amount of annual interest charges on all bonds
then outstanding under the 1940 Indenture, including the bonds then applied for,
and (ii) at least 85% of such required  minimum amount of Net Earnings  consists
of Net  Operating  Revenues  from the Public  Utility  Property of the  Company.
(Articles IV, V, and VI)

         Bonds  issuable under the 1940 Indenture are available as the basis for
the issuance of  securities  under the  Mortgage.  As of March 31, 1997,  on the
basis of the most restrictive provisions described above, the Company would have
been entitled to issue an aggregate of at least $241 million of additional bonds
under the 1940 Indenture.

Acquisition of Property Subject to Prior Liens

         The 1940  Indenture  prohibits the Company from  acquiring any property
subject to a prior  lien,  or placing  any prior lien on property at the time of
acquisition  thereof, if either the principal amount of indebtedness  secured by
prior liens on such  property  exceeds 60% of the cost or the fair value of such
property,  whichever  shall be less,  or the Net  Earnings  of the Company for a
period of 12 months  within  the 15 months  immediately  preceding  the month in
which the  property is to be acquired  shall not have been at least equal to two
times the aggregate  amount of the annual interest charges on the Secured Bonded
Debt of the Company; provided,  however, that if the Net Earnings of the Company
for the  above-stated  period  shall have been at least equal to three times the
aggregate  amount of the annual  interest  charges on the Secured Bonded Debt of
the Company, then the 60% limitation shall not apply. In the case of each of the
foregoing  Net  Earnings  requirements,  such Net  Earnings  must consist of Net
Operating  Revenues from Public Utility  Property to an extent at least equal to
85% of two or three  times,  as the case may be,  the said  aggregate  amount of
annual interest charges. (Section 83)

Maintenance and Renewal

         The 1940  Indenture  provides that the Company will, for each year, pay
or cause to be paid to the  Trustee,  an  amount  in cash,  as and for a renewal
fund,  equal  to  2-1/2%  (or such  different  percentage  as may be fixed  upon
certification by an independent  engineer that such change in percentage rate is
desirable and justified) of the average gross book value during such year of all
of the depreciable tangible Public Utility Property of the Company (with certain
specified exceptions).  The percentage is currently set at 2-1/2%. The Company's
obligation  to pay such  amount to the  Trustee in cash may at the option of the
Company be  satisfied in whole or in part by the  certification  of unused Gross
Bondable  Additions or the  certification of unused bond  retirements,  or both.
(Section 74)



                                       19


<PAGE>

         The 1940  Indenture  also provides (i) that the Company shall  maintain
the  mortgaged  properties  in good  repair  and  working  order;  (ii) that the
Company,  upon written  request served upon it and the Trustee by the holders of
at least 25% in  principal  amount of the bonds  outstanding,  shall  cause such
properties  to be inspected by an  independent  engineer (not more often than at
five-year  intervals)  to  determine  whether they have been so  maintained  and
whether any property,  not retired on the books, should be so classified for the
purpose (among others) of computing Net Bondable  Additions;  and (iii) that the
Company  shall  make  good  any  deficiency  in  maintenance  disclosed  by such
engineer's report as rendered or as modified by arbitration. (Section 73)

Limitations on Dividends on Common Stock

         The 1940  Indenture  prohibits the Company from declaring or paying any
dividends  (except stock dividends or dividends paid out of the proceeds of sale
of stock),  or making other  distributions  on, or acquisitions of, stock unless
immediately  after such dividend,  distribution or acquisition the net income of
the Company  available for dividends (as defined),  for the period from December
31,  1945,  to  and  including  the  date  of  such  dividend,  distribution  or
acquisition,  plus the sum of $250,000 shall at least equal all payments made in
respect of all such dividends, distributions or acquisitions during said period;
provided that such  restriction  shall not apply to the acquisition of stock out
of the proceeds  from the sale of, or in exchange for, any other shares of stock
or securities  representing an equity interest subordinate to all debts, secured
or  unsecured.  (Section  85) Giving  effect to the use of the  proceeds  of the
Securities  offered  hereby,  retained  earnings are not  restricted  under this
provision.

Modification of the 1940 Indenture

         In general,  modifications  or  alterations  of the 1940  Indenture and
indentures supplemental thereto and of the rights and obligations of the Company
and of the holders of the bonds may,  with the approval of the Company,  be made
at a meeting of bondholders  upon the affirmative  vote of the holders of 75% or
more of the  aggregate  principal  amount  of the  bonds  entitled  to vote with
respect to the matter  involved,  but no such  modifications  or alterations are
permitted  with respect to certain  basic  matters,  such as terms of payment of
principal or interest on the bonds or the creation of liens ranking prior to, or
on a parity with, the lien of the 1940 Indenture.  (Section 167) (See "Voting of
Class "A" Bonds" below.)

Defaults and Notice Thereof

         Defaults under the 1940 Indenture are defined in substance as being (a)
failure to pay principal or any  installment  of interest on any bond on the due
date;  (b)  failure to observe  any  covenant  or  condition  prescribed  by the
provisions  of any sinking  fund created for the benefit of bonds of any series;
(c) failure to perform any other  covenant or agreement  of the 1940  Indenture,
which failure shall continue for a period of 60 days after a written demand that
such  failure be cured has been  mailed to the  Company by the Trustee or to the
Company by the  holders of 15% in  principal  amount of the bonds;  (d)  certain
events relating to  reorganization,  bankruptcy and insolvency of the Company or
the  appointment of a receiver or trustee of the Company's  property;  (e) final
judgment in excess of $100,000  against the Company  which is not  discharged or
stayed within 30 days; or (f) the assumption by any  governmental  agency or any
court at the instance of any governmental  agency of custody of the whole or any
substantial part of the Trust Estate or of control over the Company's affairs or
operations to the exclusion of management by the Company. (Section 105)

         Upon the occurrence of a Default,  the 1940 Indenture  Trustee may, and
upon request of the holders of a majority in principal amount of the bonds shall
(and the holders of at least 25% in principal amount of the bonds may, by notice
in writing to the  Company),  declare the  principal  of and interest on all the
bonds to be immediately due and payable. (Section 107)

         The 1940 Indenture Trustee is required to give notice of any Default to
holders  of bonds  whose  names are on file  with it  within  90 days  after the
occurrence of a Default known to it, unless such Default has been cured prior to
the giving of such  notice and except that such  notice may be  withheld,  other
than as to a Default in payment of principal  or interest or of any  installment
of any sinking fund, if the 1940 Indenture Trustee determines in good faith that
such withholding is in the interest of the holders of bonds. (Section 106)

         The  holders of not less than a majority in  principal  amount of bonds
then  outstanding  may  direct  the time,  method  and place of  conducting  any
proceeding for any remedy available to the 1940 Indenture  Trustee,  or exercise
any trust or power conferred upon the 1940 Indenture Trustee. (Section 110)

         The Company  must file an annual  Certificate  with the 1940  Indenture
Trustee as to compliance with the conditions and covenants of the 1940 Indenture
and as to the absence of default with respect to any of the covenants  contained
in the 1940 Indenture. (Section 103)

Voting of Class "A" Bonds

         The Trustee  will,  as holder of any Class "A" Bonds  issued  under the
1940 Indenture, attend such meetings of bondholders under the 1940 Indenture, or
deliver its proxy in connection therewith,  as relate to matters with respect to
which it is entitled to vote or consent.  The Mortgage provides that, so long as
no Event of Default as defined in the Mortgage  has  occurred or is  continuing,
the Trustee will, as holder of such Class "A" Bonds, vote or consent:

         (a)      in favor of amendments or  modifications to the 1940 Indenture
of substantially  the same tenor and effect as the following,  together with all
amendments and modifications required to effectuate the following:

                  (i)      to provide that, whenever the 1940 Indenture requires


                                       21


<PAGE>
                           authorization  by, or a  resolution  of, the Board of
                           Directors  for the  issuance  of a series of bonds or
                           the   determination   of  the  terms   thereof,   the
                           requirement  shall be  satisfied  if the action taken
                           would be  sufficient  for the issuance of a series of
                           bonds,  or the  determination  of the terms  thereof,
                           under the Mortgage;

                  (ii)     to eliminate the renewal fund and to provide that, to
                           the extent  Property  Additions  have been taken as a
                           credit,   or  cash  held  by  the  Trustee  has  been
                           deposited,  to satisfy the renewal fund  requirements
                           (or to satisfy any sinking fund requirement  which is
                           no longer in effect),  such  Property  Additions  and
                           cash  may be used  for any  purpose  under  the  1940
                           Indenture  (including  as a basis for the issuance of
                           bonds)  as if they  had  never  been so  credited  or
                           deposited;

                  (iii)    to permit  bonds to be issued in a  principal  amount
                           equal  to  75%,  instead  of  60%,  of  Net  Bondable
                           Additions;

                  (iv)     to eliminate  the Net Earnings  requirements  for all
                           purposes,  including in connection  with the issuance
                           of bonds;

                  (v)      to broaden the definition of "Property  Additions" to
                           include all  tangible  property  owned by the Company
                           and subject to the lien of the 1940 Indenture;

                  (vi)     to  eliminate  the  restrictions  on the  payment  of
                           dividends  on, or the  making of other  distributions
                           on, or acquisitions of, stock;

                  (vii)    to  eliminate  most  restrictions  on purchase  money
                           obligations  which may be received  as  consideration
                           for the release of property from the lien of the 1940
                           Indenture;

                  (viii)   to permit the release,  without compliance with other
                           provisions  of the 1940  Indenture,  of any  property
                           provided  that (1) the  release  will not  impair the
                           electric  business of the Company in contravention of
                           the provisions of the 1940 Indenture and (2) the fair
                           value  of   property   released   pursuant   to  this
                           provision,  together with the fair value of all other
                           property  so released  in the then  current  calendar
                           year,  shall not exceed the greater of $5,000,000 and
                           3% of the  aggregate  principal  amount of bonds then
                           outstanding under the 1940 Indenture;

                  (ix)     to  modify   release   provisions   to   delete   the
                           requirement  that the  property to be released  shall
                           "no  longer  be  useful,  necessary,   profitable  or
                           advantageous   in  the   judicious   management   and
                           maintenance  of the Trust Estate or in the conduct of
                           the  business  of  the   Company"  and   substituting
                           therefor  the  requirement  that the  release  of the
                           property  would not  adversely  affect the  Company's
                           electric business;

                  (x)      to permit  the  withdrawal  by the  Company,  without
                           compliance   with  other   provisions   of  the  1940
                           Indenture,  of cash in an amount, together with other
                           amounts  paid over to the  Company  pursuant  to this
                           provision in the then current  calendar  year,  up to
                           the  greater of  $5,000,000  and 3% of the  aggregate
                           principal amount of the bonds then outstanding  under
                           the 1940  Indenture;  provided that such cash must be
                           expended for Property Additions;

                  (xi)     to increase  the amount of cash  withdrawable  by the
                           Company  on the basis of  retired  bonds from 100% of
                           the  principal  amount of such bonds to  133-1/3%  of
                           such principal amount;

                  (xii)    to eliminate most  restrictions on the acquisition of
                           property subject to a prior lien;

                                     22
<PAGE>
                  (xiii)   to  limit  the   insurance   coverage  that  must  be
                           maintained by the Company to fire  insurance only and
                           to raise the  minimum  dollar  amount of any one fire
                           loss  which  must be  payable  to the 1940  Indenture
                           Trustee  from  $10,000  to an  amount  equal  to  the
                           greater  of  $5,000,000   and  3%  of  the  aggregate
                           principal amount of bonds then outstanding  under the
                           1940 Indenture;

                  (xiv)    to modify the definition of "Defaults" under the 1940
                           Indenture to be substantially  the same as "Events of
                           Default" under the Mortgage;

                  (xv)     to modify the  provisions  of the 1940  Indenture for
                           the  acceleration of the maturity of bonds to provide
                           that (1) action by the holders of a majority  (rather
                           than the current 25%) in principal amount of the then
                           outstanding  bonds  is  required  to  accelerate  the
                           maturity of all  outstanding  bonds upon  Default and
                           (2) any such  acceleration  and its  consequences are
                           automatically rescinded (rather than at the option of
                           the holders as is currently provided) upon the curing
                           of all Defaults;

                  (xvi)    to reduce  the  quorum  requirements  for  bondholder
                           meetings from 75% to a majority; and

                  (xvii)   to modify the  remedies  provisions  to increase to a
                           majority  from 25% the  percentage  of the  principal
                           amount of  outstanding  bonds,  the  holders of which
                           must have requested  that the 1940 Indenture  Trustee
                           take action before  individual  holders may institute
                           suits against the Company.

         (b)      with respect to any other  amendments or  modifications to the
1940 Indenture as follows:

         the  Trustee  will  vote all  Class  "A"  Bonds  issued  under the 1940
         Indenture   then  held  by  it,  or  consent  with   respect   thereto,
         proportionately  with  what is  reasonably  believed  to be the vote or
         consent of the  holders of all other bonds  Outstanding  under the 1940
         Indenture,  the  holders  of which  are  eligible  to vote or  consent;
         provided,  however,  that (i) at any time the Class "A" Bonds under the
         1940  Indenture  held  by the  Trustee  constitute  a  majority  of the
         principal  amount of the Outstanding  bonds under the 1940 Indenture or
         (ii) at any time such  Class "A" Bonds held by the  Trustee  constitute
         less  than  such a  majority  but  there  is a  proposed  amendment  or
         modification  of the 1940 Indenture  which,  if it were an amendment or
         modification of the Mortgage (See  "DESCRIPTION OF THE COLLATERAL TRUST
         BONDS - Modification  of the  Mortgage"),  would require the consent of
         Holders, then, in either case, the Trustee may only vote such Class "A"
         Bonds in accordance with the vote of the Holders of at least a majority
         of the principal amount of the bonds casting a vote and shall seek that
         vote in accordance  with the  provisions of the Mortgage  applicable to
         required votes of Holders in respect of amendments or  modifications to
         the Mortgage.

Security

         The ISU 1923  Indenture  constitutes a direct first  mortgage lien upon
substantially  all of the property and rights of Iowa  Southern  existing at the
time of the IE-ISU merger on December 31, 1993 and upon extensions and additions
appurtenant  to such  property,  with certain  exceptions  for certain  types of
property (including accounts  receivable) as provided in the ISU 1923 Indenture,
and subject only to permitted liens. (Granting Clauses)

         Any  bonds  issued  under the ISU 1923  Indenture  as the basis for the
issuance of Bonds under the  Mortgage  will be secured  equally and ratably with
the bonds of all other series then outstanding under the ISU 1923 Indenture.

Effect of the IE-ISU Merger on the ISU 1923 Indenture

         The  merger  of IE and ISU  did not  impair  the  lien of the ISU  1923
Indenture  or any of the rights or powers of the ISU  Indenture  Trustees or the
bondholders  under the ISU 1923  Indenture.  (Article  XVI)  Subsequent  to that
merger, the Company became the successor to ISU under the ISU 1923 Indenture.

Issuance of Additional Bonds

         The ISU  1923  Indenture  does  not fix an  overall  limitation  on the
aggregate  principal  amount  of the bonds of all  series  that may be issued or
outstanding thereunder. (Section 2.01)

         Provided that the Earnings  Applicable to Bond Interest for a period of
twelve  consecutive  calendar  months  within  the  fifteen  months  immediately
preceding  issuance are at least twice the annual  interest  requirements of the
bonds  applied  for and all bonds and Prior Lien Bonds  outstanding,  additional
bonds of any series may be issued:

                  (a)      in an aggregate principal amount not exceeding 60% of
         the Cost or Fair Value,  whichever is less, of Property Additions after
         adjustments to offset  retirements and amounts removed from the utility
         plant or fixed capital  accounts of the former Iowa  Southern  (Article
         V);

                  (b)      in an aggregate  principal  amount not  exceeding the
         aggregate  principal  amount of bonds  which  shall  have been  retired
         (other than bonds retired  through the use of certain  funds)  (Article
         VI);

                  (c)      upon deposit of cash with the ISU Corporate  Trustee,
         in an amount equal to the principal amount of the bonds to be so issued
         (and such cash may be  withdrawn  by the  Company in a sum equal to the
         aggregate  principal  amount of the bonds which  could be issued  under
         clause (a) or (b) above). (Article VII)

         Bonds  issuable under the ISU 1923 Indenture are available as the basis
for the issuance of securities under the Mortgage.  As of March 31, 1997, on the
basis of the most restrictive provisions described above, the Company would have
been entitled to issue at least $167 million of  additional  bonds under the ISU
1923 Indenture.

Maintenance Fund

         The  ISU  1923  Indenture  provides  that so long  as  bonds  shall  be
outstanding,  the Company will pay to the ISU Corporate Trustee  annually,  as a
maintenance  fund, a sum of money equal to 15% of the gross operating revenue of
the Company  derived  during the calendar year  preceding  such payment from the
operation  of the  physical  properties  subject  to the  lien of the  ISU  1923
Indenture after  deducting (1) all gross  operating  revenue derived during such
period from the operation of property  subject to a prior lien and (2) an amount
equal to the total  cost to the  Company of  electric  energy  and  natural  gas
purchased by it (and allocable to operations of property  subject to the lien of
the ISU 1923 Indenture) during such period with certain deductions.  The Company
is entitled to credits against such annual payment for certain amounts  expended
for maintenance and repairs and Unapplied Balance of Property Additions, retired
bonds,  and other  matters.  Any moneys  deposited  by the Company  with the ISU
Corporate Trustee in the maintenance fund will, upon the request of the Company,
be applied by the ISU  Corporate  Trustee to the purchase or redemption of bonds
or may be withdrawn by the Company in certain circumstances. (Article XII)


                                       24

Substitutions and Releases

         Generally,  property  subject to the lien of the ISU 1923 Indenture may
be released  only upon the deposit or pledge with the ISU  Corporate  Trustee of
cash, purchase money obligations,  securities,  or the certification of property
additions or, in certain  instances,  upon the substitution of other property of
equivalent  value.  The  Company may also,  under  certain  conditions,  without
release, terminate,  change, or assent to the modification of leases, easements,
franchises, and governmental permits. (Article XI)

Satisfaction and Discharge of Indenture

         If the  Company  shall pay the  principal  of,  premium  (if any),  and
interest on all outstanding bonds issued under the ISU 1923 Indenture (bonds for
the payment or redemption of which  necessary funds have been deposited with the
ISU Corporate Trustee being deemed paid),  then the ISU Indenture  Trustees may,
and upon the request of the Company shall,  cancel and discharge the lien of the
ISU 1923  Indenture  and  reconvey  to the  Company  the  mortgaged  and pledged
property. (Article XIX)

Modification of the ISU 1923 Indenture

         To the  extent  permitted  by the  terms  of the  ISU  1923  Indenture,
modification   or  alteration  of  the  ISU  1923  Indenture  or  any  indenture
supplemental  thereto,  and of the rights and  obligations of the Company and of
ISU  bondholders,  may be made with the consent of the Company by an affirmative
vote of the holders of not less than 80% in principal  amount of the outstanding
bonds issued under the ISU 1923  Indenture  and entitled to vote at a meeting of
bondholders  and by an  affirmative  vote of the holders of not less than 80% of
the  principal  amount  of such  bonds of the  series  affected  by the  change;
provided, however, that no such modification or alteration intended to effect or
permit the extension of the maturity of the principal of any bond, the reduction
in the rate of  interest  thereon,  or any  other  modification  in the terms of
payment of such  principal or interest,  or the taking of certain other actions,
such as creating  liens ranking prior to, or on parity with, the lien of the ISU
1923  Indenture,  shall be  effective as to any bond the holder of which has not
assented to such modification or alteration.  (Article XX) (See "Voting of Class
"A" Bonds" below.)

         The  Company  may fail or omit to  comply  with  certain  covenants  or
conditions of the ISU 1923 Indenture with the written  consent of the holders of
at least 66 2/3% of the principal  amount of all outstanding  bonds issued under
the ISU 1923 Indenture. (Section 15.19)

Defaults and Notice Thereof

         Defaults under the ISU 1923 Indenture are defined in substance as being
(a) failure to pay  principal  of, or premium (if any) on, any bond issued under
the ISU 1923  Indenture;  (b) failure to pay any  installment of interest on any
such bond,  and such failure  continues for 30 days;  (c) failure to observe any
covenant or condition  prescribed by the  provisions of any sinking fund created
for the  benefit  of such bonds of any  series;  (d)  failure by the  Company to
perform  any  other  covenant  or  agreement  in such  bonds  or in the ISU 1923
Indenture, and such failure continues for 60 days after written notice is given;
and (e) certain events relating to reorganization,  bankruptcy and insolvency of
the Company, and the appointment of a receiver. (Section 15.01)

         The ISU 1923  Indenture  Trustees  are  required  to give notice of any
default to bondholders within 90 days after the occurrence thereof,  unless such
default is cured before the giving of such notice (except in the case of certain
defaults,  notice of which is not to be given by such Trustees until at least 60
days after the  occurrence  thereof).  The ISU  Indenture  Trustees may withhold
notice of default (except in the payment of principal of, or interest or premium
(if any) on, any of the bonds or in the payment of any sinking  fund or purchase
fund installment) if the ISU Corporate Trustee  determines that such withholding
is in the interest of the bondholders. (Section 17.11)


                                       25


<PAGE>


         Holders of a majority of the principal amount of outstanding  bonds may
direct the method,  time, and place of conducting any proceedings for any remedy
available to the ISU Indenture  Trustees for any sale of the property subject to
the  lien of the ISU  1923  Indenture,  or for the  foreclosure  of the ISU 1923
Indenture,  or for the appointment of a receiver, or for the taking of any other
action  authorized  by the  ISU  1923  Indenture  in  respect  of a  default  or
refraining therefrom. (Section 15.05)

         No  holder  of any bond or coupon  shall  have any right to any  remedy
under the ISU 1923 Indenture,  unless such holder has given prior written notice
to the ISU 1923 Indenture  Trustees of the default,  25% in aggregate  principal
amount of the bonds  outstanding  have made  prior  written  request  to the ISU
Corporate  Trustee  and have  afforded  reasonable  opportunity  to the 1923 ISU
Indenture  Trustees to pursue the remedy in the trustees' own names, and the ISU
1923 Indenture Trustees have been offered adequate indemnity for costs, expenses
and liabilities which may be incurred thereby. (Section 15.15)

         The  Company  must file an annual  Certificate  with the ISU  Corporate
Trustee as to  compliance  with the  conditions  and  covenants  of the ISU 1923
Indenture  and as to the absence of default with respect to any of the covenants
contained in the ISU 1923 Indenture. (Section 14.03)

Voting of Class "A" Bonds

         The Trustee will, as holder of any Class "A" Bonds issued under the ISU
1923  Indenture,  attend  such  meetings  of  bondholders  under  the  ISU  1923
Indenture,  or deliver its proxy in connection  therewith,  as relate to matters
with respect to which it is entitled to vote or consent.  The Mortgage  provides
that,  so long as no Event of Default as defined in the Mortgage has occurred or
is  continuing,  the Trustee  will,  as holder of such Class "A" Bonds,  vote or
consent:

         (a)      in  favor  of  amendments  or  modifications  to the ISU  1923
Indenture of substantially the same tenor and effect as the following,  together
with all amendments and modifications required to effectuate the following:

                  (i)      to  provide  that,  whenever  the ISU 1923  Indenture
                           requires  authorization  by, or a resolution  of, the
                           Board of Directors or an Executive  Committee thereof
                           for  the  issuance  of  a  series  of  bonds  or  the
                           determination  of the terms thereof,  the requirement
                           shall  be  satisfied  if the  action  taken  would be
                           sufficient for the issuance of a series of bonds,  or
                           the  determination  of the terms  thereof,  under the
                           Mortgage;

                  (ii)     to  eliminate  the  maintenance  fund and to  provide
                           that,  to the  extent  Property  Additions  or  bonds
                           previously  outstanding  have been taken as a credit,
                           or cash held by the ISU  Corporate  Trustee  has been
                           deposited,  in each case to satisfy  the  Maintenance
                           Fund   Requirements,    such   Property    Additions,
                           previously outstanding bonds and cash may be used for
                           any purpose under the ISU 1923  Indenture  (including
                           as a basis for the  issuance of bonds) as if they had
                           never been so credited or deposited;

                  (iii)    to permit  bonds to be issued in a  principal  amount
                           equal to 75%, instead of 60%, of Property Additions;

                  (iv)     to eliminate  the Net Earnings  requirements  for all
                           purposes,  including in connection  with the issuance

                  (v)      to broaden the definition of "Property  Additions" to

                  (viii)   to increase  the amount of cash  withdrawable  by the
                           Company on the basis of retired property from 100% of
                           the cost or fair value of such  property  to 133-1/3%

                           Trustees  from  $10,000  to an  amount  equal  to the
                           greater  of  $5,000,000   and  3%  of  the  aggregate
                           principal amount of bonds then outstanding  under the
                           ISU 1923 Indenture;

                  (x)      to modify the definition of "defaults"  under the ISU
                           1923  Indenture  to  be  substantially  the  same  as
                           "Events of Default" under the Mortgage;

                  (xi)     to modify the  provisions  of the ISU 1923  Indenture
                           for the  acceleration  of the  maturity  of  bonds to
                           provide  that (1) action by the holders of a majority
                           (rather than the current 25%) in principal  amount of
                           the then outstanding  bonds is required to accelerate
                           the  maturity of all  outstanding  bonds upon default
                           and (2) any such  acceleration  and its  consequences
                           are  automatically  rescinded  (rather  than  at  the
                           option of the holders as is currently  provided) upon
                           the curing of all defaults;

                  (xii)    to reduce  the  quorum  requirements  for  bondholder
                           meetings from 80% to a majority; and

                  (xiii)   to modify the  remedies  provisions  to increase to a
                           majority  from 25% the  percentage  of the  principal
                           amount  of  bonds,  the  holders  of which  must have
                           requested  the ISU  Corporate  Trustee to take action
                           before individual holders may institute suits against
                           the Company.

         (b)      with respect to any other  amendments or  modifications to the
ISU 1923 Indenture, as follows:

         the  Trustee  will vote all Class "A" Bonds  issued  under the ISU 1923
         Indenture   then  held  by  it,  or  consent  with   respect   thereto,
         proportionately  with  what is  reasonably  believed  to be the vote or
         consent of the  holders of all other  bonds  outstanding  under the ISU
         1923  Indenture,  the holders of which are eligible to vote or consent;
         provided,  however, that (i) at any time such Class "A" Bonds under the
         ISU 1923  Indenture  held by the Trustee  constitute  a majority of the
         principal amount of the Outstanding  bonds under the ISU 1923 Indenture
         or (ii) at any time such Class "A" Bonds held by the Trustee constitute
         less  than  such a  majority  but  there  is a  proposed  amendment  or
         modification  of the ISU 1923 Indenture  which, if it were an amendment
         or  modification  of the Mortgage (See  "DESCRIPTION  OF THE COLLATERAL
         TRUST BONDS - Modification of the Mortgage"), would require the consent
         of Holders,  then, in either case, the Trustee may only vote such Class
         "A"  Bonds in  accordance  with the vote of the  Holders  of at least a
         majority of the principal  amount of the securities  casting a vote and
         shall seek that vote in accordance  with the provisions of the Mortgage
         applicable  to required  votes of Holders in respect of  amendments  or
         modifications to the Mortgage.

Subordination

         The Subordinated  Indenture  provides that payment of the principal of,
premium,  if any, and interest on Subordinated  Debentures is  subordinated  and
subject  in  right  of  payment  to the  prior  payment  in full  of all  Senior
Indebtedness  (as  defined  below)  of  the  Company,  all  as  provided  in the
Subordinated  Indenture. No payment of principal of (including redemption of and
sinking fund payments), premium, if any, or interest on, Subordinated Debentures
may be made if payment of principal,  premium,  interest or any other payment on
any Senior  Indebtedness is not made when due, any applicable  grace period with
respect to such  default has ended and such default has not been cured or waived
or ceased to exist,  or if the  maturity  on any  Senior  Indebtedness  has been
accelerated  because of default.  Upon any distribution of assets of the Company
to creditors upon any dissolution,  winding up,  liquidation or  reorganization,
whether voluntary or involuntary or in bankruptcy,  insolvency,  receivership or
other  proceedings,  all principal of,  premium,  if any, and interest due or to
become due on, all Senior  Indebtedness  must be paid in full before any payment
on the  Subordinated  Debentures.  Subject to the  payment in full of all Senior
Indebtedness,  the rights of the  holders  of  Subordinated  Debentures  will be
subrogated  to the  rights of the  holders  of Senior  Indebtedness  to  receive
payments or distributions  applicable to Senior  Indebtedness  until all amounts
owing on Subordinated Debentures are paid in full. (Sections 1501 - 1504)

         The term  "Senior  Indebtedness"  means  all  obligations  (other  than
non-recourse  obligations  and the  indebtedness  issued under the  Subordinated
Indenture)  of, or  guaranteed  or assumed by, the Company for  borrowed  money,
including both senior and  subordinated  indebtedness  for borrowed money (other
than the Subordinated  Debentures),  or for the payment of money relating to any
lease which is capitalized on the consolidated  balance sheet of the Company and
its subsidiaries in accordance with generally accepted accounting principles, or
evidenced by bonds, debentures,  notes or other similar instruments, and in each
case, amendments, renewals, extensions, modifications and refundings of any such
indebtedness or obligations, whether existing as of the date of the Subordinated
Indenture or  subsequently  incurred by the Company.  (Section  101) Such Senior
Indebtedness  shall  continue  to be Senior  Indebtedness  and  entitled  to the
benefits  of  the  subordination   provisions  irrespective  of  any  amendment,
modification or waiver of any terms of such Senior Indebtedness. (Section 1509)

         The  Subordinated  Indenture  does not  limit the  aggregate  amount of
Senior   Indebtedness  that  may  be  issued.  As  of  March  31,  1997,  Senior
Indebtedness of the Company aggregated approximately $708 million.

Form, Exchange, and Transfer

         Unless  otherwise  specified in the applicable  Prospectus  Supplement,
Subordinated Debentures of each series will be issuable only in fully registered
form without coupons and in  denominations  of $1,000 and any integral  multiple
thereof. (Sections 201 and 302)

         At the option of the Holder,  subject to the terms of the  Subordinated
Indenture  and the  limitations  applicable to global  securities,  Subordinated
Debentures of any series will be exchangeable for other Subordinated  Debentures
of the  same  series,  of any  authorized  denomination  and of like  tenor  and
aggregate principal amount. (Section 305)

         Subject to the terms of the Subordinated  Indenture and the limitations
applicable to global  securities,  Subordinated  Debentures may be presented for
exchange as  provided  above for  registration  of  transfer  (duly  endorsed or
accompanied  by a duly  executed  instrument  of  transfer) at the office of the
Security  Registrar or at the office of any  transfer  agent  designated  by the
Company for such purpose.  Unless otherwise indicated, no service charge will be
made for any  registration of transfer or exchange of  Subordinated  Debentures,
but the  Company  may require  payment of a sum  sufficient  to cover any tax or
other governmental  charge payable in connection  therewith.  Every Subordinated
Debenture  presented or  surrendered  for  registration  of transfer or exchange
shall (if so required by the Company, the Subordinated  Indenture Trustee or the
Security  Registrar)  be duly  endorsed or  accompanied  by an executed  written
instrument of transfer in form  satisfactory  to the Company,  the  Subordinated
Indenture  Trustee or the Security  Registrar.  (Section 305) Any transfer agent
(in addition to the Security Registrar)  initially designated by the Company for
any  Subordinated   Debenture  will  be  named  in  the  applicable   Prospectus
Supplement.  The Company may at any time designate additional transfer agents or
rescind the  designation of any transfer agent or approve a change in the office
through which any transfer agent acts,  except that the Company will be required
to  maintain a transfer  agent in each  Place of  Payment  for the  Subordinated
Debentures  of each series.  The Company may perform all functions of any office
or agency. (Section 602)

         The Company  shall not be required to execute or register  the transfer
of or the exchange of any Subordinated Debenture, or any Tranche thereof, during
a  period  of  15  days  preceding  the  notice  to  be  given  identifying  the
Subordinated Debenture called for redemption,  or any Subordinated Debentures so
selected for redemption,  in whole or in part, except the unredeemed  portion of
any such Subordinated Debenture being redeemed in part. (Section 305)

Payment and Paying Agent

         Unless  otherwise  indicated in the applicable  Prospectus  Supplement,
payment of interest on a  Subordinated  Debenture on any  Interest  Payment Date
will be made to the person in whose name such Subordinated  Debenture (or one or
more  Predecessor  Securities)  is  registered  at the close of  business on the
Regular Record Date for such interest. (Section 307)

         Unless  otherwise  indicated in the applicable  Prospectus  Supplement,
principal of and any  interest on the  Subordinated  Debentures  of a particular
series  will be payable at the office of such Paying  Agent or Paying  Agents as
the Company may designate for such purpose from time to time.  Unless  otherwise
indicated in the applicable Prospectus Supplement, the corporate trust office of
the Subordinated  Indenture  Trustee in New York, New York will be designated as
the  Company's  sole  Paying  Agent for  payment  with  respect to  Subordinated
Debentures of each series.  Any other Paying Agents initially  designated by the
Company for the Subordinated  Debentures of a particular series will be named in
the  applicable  Prospectus  Supplement.  The Company may at any time  designate
additional  Paying  Agents or rescind  the  designation  of any Paying  Agent or
approve a change in the office through which any Paying Agent acts,  except that
the Company will be required to maintain a Paying Agent in each Place of Payment
for the Subordinated Debentures of a particular series. (Section 602)

         Any moneys  deposited  by the  Company  with the  Trustee or any Paying
Agent for the  payment of the  principal  of or any  premium or  interest on any
Subordinated  Debenture  which  remains  unclaimed at the end of two years after
such  principal,  premium or interest has become due and payable will be paid to
the  Company,  and the Holder of such  Subordinated  Debenture,  as an unsecured
general  creditor and not as a Holder,  thereafter  may look only to the Company
for payment thereof. (Section 603)

Redemption

         Any terms for the  optional or  mandatory  redemption  of  Subordinated
Debentures  will be set  forth  in the  applicable  Prospectus  Supplement  or a
supplement  thereto.  Except as shall  otherwise  be provided in the  applicable
Prospectus   Supplement  with  respect  to  Subordinated   Debentures  that  are
redeemable  at the  option  of  the  Holder,  Subordinated  Debentures  will  be
redeemable  only upon notice by mail not less than 30 days nor more than 60 days
prior to the date fixed for redemption,  and, if less than all the  Subordinated
Debentures  of a  series,  or  any  Tranche  thereof,  are to be  redeemed,  the
particular  Subordinated  Debentures  to be  redeemed  will be  selected  by the
Securities  Registrar  by such  method as shall be provided  for any  particular
series,  or in the  absence  of any such  provision,  by such  method  of random
selection as the Security  Registrar deems fair and  appropriate.  (Sections 403
and 404)

         Any notice of  redemption  at the option of the  Company may state that
such redemption will be conditional  upon receipt by the Paying Agent or Agents,
on or prior to the date fixed for such  redemption,  of money  sufficient to pay
the principal of and premium, if any, and interest, if any, on such Subordinated
Debentures and that if such money has not been so received,  such notice will be
of no force and effect  and the  Company  will not be  required  to redeem  such
Subordinated Debentures. (Section 404)

consolidate  with or merge into any other  corporation  or convey,  transfer  or
lease its  properties  and assets  substantially  as an  entirety to any Person,
unless  (i) the  corporation  formed  by such  consolidation  or into  which the
Company is merged or the Person which  acquires by  conveyance  or transfer,  or
which  leases,  the  properties  and assets of the Company  substantially  as an
entirety shall be a Person organized and existing under the laws of any domestic
jurisdiction  and  shall  expressly  assume  the  Company's  obligations  on the
Subordinated Debentures and under the Subordinated  Indenture,  (ii) immediately
after giving effect to the transaction,  no Event of Default shall have occurred
and be continuing, and (iii) the Company will have delivered to the Subordinated
Indenture Trustee an Officer's Certificate and an Opinion of Counsel as provided
in the Subordinated Indenture. (Section 1101)

Events of Default

         Each of the  following  will  constitute  an Event of Default under the
Subordinated  Indenture with respect to  Subordinated  Debentures of any series:
(a) failure to pay any interest on any  Subordinated  Debentures  of such series
within  60 days  after  the same  becomes  due and  payable;  provided,  that an
extension of an interest payment period by the Company permitted by the terms of
the series shall not constitute a failure to pay interest for this purpose;  (b)
failure to pay principal of or premium, if any, on any Subordinated Debenture of
such series  within three  business days after the same becomes due and payable;
(c)  failure to  perform  or breach of any other  covenant  or  warranty  of the
Company in the Subordinated  Indenture (other than a covenant or warranty of the
Company in the  Subordinated  Indenture  solely  for the  benefit of one or more
series of  Subordinated  Debentures  other than such  series)  for 60 days after
written notice to the Company by the Subordinated  Indenture Trustee,  or to the
Company and the Subordinated Indenture Trustee by the Holders of at least 33% in
principal amount of the Subordinated Debentures of such series Outstanding under
the  Subordinated  Indenture  as provided  in the  Subordinated  Indenture;  (d)
certain events of bankruptcy,  insolvency or  reorganization;  and (e) any other
Event of Default specified in the applicable  Prospectus Supplement with respect
to Subordinated Debentures of a particular series. (Section 801)

         An Event of Default with respect to the Subordinated Debentures may not
necessarily  constitute  an Event of Default  with  respect to the  Subordinated
Debentures of any other series issued under the Subordinated Indenture.

         If an Event of  Default  with  respect  to any  series of  Subordinated
Debentures  occurs and is  continuing,  then either the  Subordinated  Indenture
Trustee  or the  Holders  of  not  less  than  33% in  principal  amount  of the
Outstanding  Subordinated  Debentures  of such series may declare the  principal
amount  (or  if  the  Subordinated   Debentures  of  such  series  are  Discount
Securities,  such portion of the principal  amount hereof as may be specified in
the applicable Prospectus  Supplement) of all of the Subordinated  Debentures of
such series to be due and payable  immediately;  provided,  however,  that if an
Event of Default  occurs and is continuing  with respect to more than one series
of Subordinated Debentures, the Subordinated Indenture Trustee or the Holders of
not less than 33% in aggregate principal amount of the Outstanding Securities of
all  such  series,  considered  as one  class,  may  make  such  declaration  of
acceleration  and not the Holders of the  Subordinated  Debentures of any one of
such series.

       Subject to the provisions of the Subordinated Indenture relating to the
duties of the Subordinated  Indenture  Trustee in case an Event of Default shall
occur and be continuing,  the  Subordinated  Indenture  Trustee will be under no
obligation  to  exercise  any of its  rights  or powers  under the  Subordinated
Indenture at the request or  direction  of any Holder,  unless such Holder shall
have  offered to the  Subordinated  Indenture  Trustee  reasonable  security  or
indemnity.  (Section 903) Subject to such provisions of the  indemnification  of
the  Subordinated  Indenture  Trustee,  the Holders of a majority  in  principal
amount of the  Outstanding  Subordinated  Debentures of any series will have the
right to direct the time,  method and place of conducting any proceeding for any
remedy available to the Subordinated  Indenture Trustee, or exercising any trust
or power conferred on the Subordinated  Indenture  Trustee,  with respect to the
Subordinated Debentures of that series. (Section 812)

         No Holder of a Subordinated Debenture of any series will have any right
to institute any proceeding with respect to the Subordinated  Indenture,  or for
the appointment of a receiver or a trustee,  of for any other remedy thereunder,
unless (i) such Holder has  previously  given written notice to the Trustee of a
continuing Event of Default with respect to the Subordinated  Debentures of such
series,  (ii) the  Holders of not less than a majority  in  aggregate  principal
amount of the  Outstanding  Subordinated  Debentures  of such  series  have made
written  request  to the  Subordinated  Indenture  Trustee,  and such  Holder or
Holders have offered reasonable indemnity to the Subordinated Indenture Trustee,
to institute  such  proceeding as trustee and (iii) the  Subordinated  Indenture
Trustee has failed to institute such  proceeding,  and has not received from the
Holders  of  a  majority  in  aggregate  principal  amount  of  the  Outstanding
Subordinated  Debentures  of that  series a  direction  inconsistent  with  such
request,  within 60 days after such  notice,  request and offer.  (Section  807)
However,  such  limitations  do not apply to a suit  instituted by a Holder of a
Subordinated Debenture for the enforcement of payment of the principal of or any
premium or interest on such  Subordinated  Debenture on or after the  applicable
due date specified in such Subordinated Debenture. (Section 808)

         The Company will be required to furnish to the  Subordinated  Indenture
Trustee  annually,  not later than  October 1 in each year,  a  statement  by an
appropriate officer as to such officer's  knowledge of the Company's  compliance
with all  conditions  and  covenants  under  the  Subordinated  Indenture,  such
compliance to be determined without regard to any period of grace or requirement
of notice under the Subordinated Indenture. (Section 606)

Right to Cure

         At any time after the declaration of  acceleration  with respect to the
Subordinated  Debentures  of any series  has been made and before a judgment  or
decree for  payment of the money due has been  obtained,  the Event or Events of
Default giving rise to such  declaration of acceleration  will,  without further
act, be deemed to have been waived,  and such  declaration and its  consequences
will, without further act, be deemed to have been rescinded and annulled, if

         (a)      the  Company  has  paid or  deposited  with  the  Subordinated
Indenture Trustee a sum sufficient to pay

                  (1)      all overdue interest on all  Subordinated  Debentures
         of such series;

                  (2)      the  principal  of  and  premium,   if  any,  on  any
         Subordinated  Debentures of such series which have become due otherwise
         than by such  declaration of acceleration  and interest  thereon at the
         rate or rates prescribed therefor in such Subordinated Debentures;

                  (3)      interest  upon overdue  interest at the rate or rates
         prescribed therefor in such Subordinated Debentures, to the extent that
         payment of such interest is lawful; and


                                       33


<PAGE>


                  (4)      all amounts due to the Subordinated Indenture Trustee
         under the Subordinated Indenture; and

         (b)  any  other  Event  or  Events  of  Default  with  respect  to  the
Subordinated  Debentures  of such  series,  other  than the  non-payment  of the
principal  of the  Subordinated  Debentures  of such series which has become due
solely  by such  declaration  of  acceleration,  have  been  cured or  waived as
provided in the Subordinated Indenture. (Section 802)

Modification and Waiver

         Without  the  consent of any  Holder of  Subordinated  Debentures,  the
Company  and the  Subordinated  Indenture  Trustee  may  enter  into one or more
supplemental  indentures to the Subordinated  Indenture for any of the following
purposes:  (a) to evidence  the  assumption  by any  permitted  successor to the
Company of the  covenants of the Company in the  Subordinated  Indenture and the
Subordinated  Debentures;  or (b) to add one or more covenants of the Company or
other  provisions  for  the  benefit  of the  Holders  of all or any  series  of
Outstanding Subordinated Debentures or to surrender any right or power conferred
upon the Company by the  Subordinated  Indenture;  or (c) to add any  additional
Events of Default with respect to all or any series of Outstanding  Subordinated
Debentures;  or (d) to change or eliminate  any  provision  of the  Subordinated
Indenture or to add any new provision to the  Subordinated  Indenture,  provided
that if such change, elimination or addition will adversely affect the interests
of the Holders of Subordinated Debentures of any series in any material respect,
such change,  elimination or addition will become effective with respect to such
series only when the consent of the Holders of such series so affected  has been
obtained or when there is no  Subordinated  Debenture  of such series  remaining
Outstanding  under the  Subordinated  Indenture;  or (e) to  provide  collateral
security for the Subordinated Debentures;  or (f) to establish the form or terms
of  Subordinated  Debentures  of any  series as  permitted  by the  Subordinated
Indenture;  or (g) to provide  for the  authentication  and  delivery  of bearer
securities  and coupons  appertaining  thereto  representing  interest,  if any,
thereon and for the procedures for the  registration,  exchange and  replacement
thereof and for giving of notice to, and the solicitation of the vote or consent
of, the Holders thereof,  and for any and all other matters incidental  thereto;
or (h) to evidence and provide for the  acceptance of  appointment of a separate
or successor  Subordinated  Indenture  Trustee under the Subordinated  Indenture
with respect to the Subordinated  Debentures of one or more series and to add or
to  change  any of the  provisions  of the  Subordinated  Indenture  as shall be
necessary to provide for or to facilitate the administration of the trusts under
the Subordinated  Indenture by more than one trustee;  or (i) to provide for the
procedures  required to permit the  utilization of a  noncertificated  system of
registration  for any series of  Subordinated  Debentures;  or (j) to change any
place where (1) the principal of and premium,  if any, and interest,  if any, on
any Subordinated  Debentures shall be payable,  (2) any Subordinated  Debentures
may be surrendered for  registration of transfer or exchange and (3) notices and
demands to or upon the  Company in respect of  Subordinated  Debentures  and the
Subordinated  Indenture may be served; or (k) to cure any ambiguity,  to correct
or supplement any defective or  inconsistent  provision or to make or change any
other  provisions  with  respect  to matters  and  questions  arising  under the
Subordinated  Indenture,  provided such changes or additions shall not adversely
affect the interests of the Holders of Subordinated  Debentures of any series in
any material respect. (Section 1201)

         The Holders of not less than a majority in aggregate  principal  amount
of the Outstanding Subordinated Debentures of any series may waive compliance by
the Company with certain restrictive  provisions of the Subordinated  Indenture.
(Section 607) The Holders of not less than a majority in principal amount of the
Outstanding  Subordinated  Debentures  of any series may waive any past  default
under the Subordinated Indenture,  except a default in the payment of principal,
premium or interest and certain  covenants and  provisions  of the  Subordinated
Indenture  that  cannot be  modified  or be amended  without  the consent of the
Holder of each  Outstanding  Subordinated  Debenture  of such  series  affected.
(Section 813)

         Without  limiting  the  generality  of  the  foregoing,  if  the  Trust
Indenture Act of 1939, as amended (the "Trust  Indenture Act"), is amended after
the date of the  Subordinated  Indenture in such a way as to require  changes to
the Subordinated Indenture or the incorporation therein of additional provisions
or so as to permit changes to, or the elimination of,  provisions  which, at the
date of the Subordinated  Indenture or at any time thereafter,  were required by
the Trust  Indenture  Act to be contained  in the  Subordinated  Indenture,  the
Subordinated  Indenture  will be deemed to have been amended so as to conform to
such amendment or to effect such changes or elimination, and the Company and the
Subordinated  Indenture  Trustee may, without the consent of any Holders,  enter
into one or more  supplemental  indentures to evidence or effect such amendment.
(Section 1201)


                                       34


<PAGE>


         Except as provided above, the consent of the Holders of not less than a
majority in aggregate  principal  amount of the  Subordinated  Debentures of all
series then Outstanding, considered as one class, is required for the purpose of
adding any provisions to, or changing in any manner,  or eliminating  any of the
provisions of, the Subordinated  Indenture  pursuant to one or more supplemental
indentures;  provided,  however,  that  if  less  than  all  of  the  series  of
Subordinated   Debentures  Outstanding  are  directly  affected  by  a  proposed
supplemental  indenture,  then the consent  only of the Holders of a majority in
aggregate principal amount of Outstanding  Subordinated Debentures of all series
so directly affected,  considered as one class, will be required;  and provided,
further,  that if the Subordinated  Debentures of any series have been issued in
more  than one  Tranche  and if the  proposed  supplemental  indenture  directly
affects  the  rights of the  Holders  of one or more,  but less  than all,  such
Tranches,  then the  consent  only of the  Holders  of a majority  in  aggregate
principal amount of the Outstanding  Subordinated  Debentures of all Tranches so
directly  affected,  considered  as one class,  will be  required;  and provided
further, that no such supplemental  indenture may (a) change the Stated Maturity
of the  principal  of, or any  installment  of  principal of or interest on, any
Subordinated  Debenture,  or reduce the principal  amount thereof or the rate of
interest  thereon  (or the amount of any  installment  of  interest  thereon) or
change the method of  calculating  such rate or reduce any premium  payable upon
the  redemption  thereof,  or reduce the amount of the principal of any Discount
Security that would be due and payable upon a  declaration  of  acceleration  of
Maturity  or  change  the coin or  currency  (or  other  property)  in which any
Subordinated  Debenture  or any premium or the interest  thereon is payable,  or
impair the right to institute suit for the enforcement of any such payment on or
after the Stated  Maturity  of any  Subordinated  Debenture  (or, in the case of
redemption,  on or after the  redemption  date)  without,  in any such case, the
consent of the Holder of such Subordinated Debenture,  (b) reduce the percentage
in principal amount of the Outstanding Subordinated Debentures of any series, or
any Tranche  thereof,  the  consent of the Holders of which is required  for any
such supplemental  indenture, or the consent of the Holders of which is required
for any waiver of compliance with any provision of the Subordinated Indenture or
any default  thereunder and its  consequences,  or reduce the  requirements  for
quorum or voting,  without,  in any such case, the consent of the Holder of each
Outstanding  Subordinated  Debenture  of such series or  Tranche,  or (c) modify
certain of the provisions of the Subordinated Indenture relating to supplemental
indentures,  waivers of certain  covenants  and  waivers of past  defaults  with
respect to the  Subordinated  Debentures of any series,  or any Tranche thereof,
without the  consent of the Holder of each  Outstanding  Subordinated  Debenture
affected  thereby.  A  supplemental  indenture  which changes or eliminates  any
covenant or other  provision of the  Subordinated  Indenture which has expressly
been  included  solely  for the  benefit  of one or more  particular  series  of
Subordinated  Debentures or one or more Tranches thereof, or modifies the rights
of the  Holders of  Subordinated  Debentures  of such  series or  Tranches  with
respect to such  covenant or other  provision,  will be deemed not to affect the
rights under the Indenture of the Holders of the Subordinated  Debentures of any
other series or Tranche. (Section 1202)

         The  Subordinated  Indenture  provides that in determining  whether the
Holders  of the  requisite  principal  amount  of the  Outstanding  Subordinated
Debentures have given any request,  demand,  authorization,  direction,  notice,
consent,  or waiver under the Subordinated  Indenture as of any date, or whether
or not a quorum is present at a meeting of Holders, (i) Subordinated  Debentures
owned by the Company or any other  obligor upon the  Subordinated  Debentures or
any Affiliate of the Company or of such other obligor (unless the Company,  such
Affiliate  or  such  obligor  owns  all   Securities   Outstanding   under  this
Subordinated Indenture, or all Outstanding  Subordinated Debentures of each such
series and each such Tranche,  as the case may be, determined  without regard to
this clause (i)) shall be disregarded and deemed not to be Outstanding; (ii) the
principal  amount of a Discount  Security that shall be deemed to be Outstanding
for such purposes shall be the amount of the principal thereof that would be due
and  payable  as of  the  date  of  such  determination  upon a  declaration  of
acceleration of the Maturity thereof as provided in the Subordinated  Indenture;
and (iii) the principal amount of a Subordinated Debenture denominated in one or
more  foreign  currencies  or a  composite  currency  that  will be deemed to be
Outstanding  will be the Dollar  equivalent,  determined  as of such date in the
manner  prescribed for such Subordinated  Debenture,  of the principal amount of
such  Subordinated  Debenture  (or,  in the  case  of a  Subordinated  Debenture
described  in clause  (ii)  above,  of the  amount  described  in such  clause).
(Section 101)

         If  the  Company  shall  solicit  from  Holders  any  request,  demand,
authorization,  direction,  notice, consent,  election, waiver or other Act, the


                                       35


<PAGE>


Company may, at its option,  by Board  Resolution,  fix in advance a record date
for the  determination  of  Holders  entitled  to  give  such  request,  demand,
authorization,  direction,  notice, consent,  election, waiver or other Act, but
the Company  shall have no  obligation to do so. If such a record date is fixed,
such request,  demand,  authorization,  direction,  notice,  consent,  election,
waiver or other Act may be given before or after such record date,  but only the
Holders of record at the close of business on the record date shall be deemed to
be Holders for the  purposes of  determining  whether  Holders of the  requisite
proportion of the Outstanding  Subordinated Debentures have authorized or agreed
or consented to such request, demand, authorization, direction, notice, consent,
direction,   waiver  or  other  Act,  and  for  that  purpose  the   Outstanding
Subordinated  Debentures  shall be computed as of the record date.  Any request,
demand, authorization, direction, notice, consent, election, waiver or other Act
of a Holder shall bind every future  Holder of the same  Subordinated  Debenture
and the Holder of every  Subordinated  Debenture issued upon the registration of
transfer  thereof  or in  exchange  therefor  or in lieu  thereof  in respect of
anything  done,  omitted or suffered to be done by the Trustee or the Company in
reliance  thereon,  whether  or not  notation  of such  action is made upon such
Subordinated Debenture. (Section 104)

Defeasance

         Unless otherwise indicated in the applicable Prospectus Supplement, any
Subordinated  Debenture, or any portion of the principal amount thereof, will be
deemed to have been paid for purposes of the Subordinated Indenture, and, at the
Company's  election,  the entire  indebtedness of the Company in respect thereof
will be  deemed  to have  been  satisfied  and  discharged,  if  there  has been
irrevocably  deposited  with the  Subordinated  Indenture  Trustee or any Paying
Agent (other than the Company),  in trust:  (a) money in an amount which will be
sufficient,  or (b) Eligible  Obligations  (as  described  below),  which do not
contain  provisions  permitting the redemption or other prepaying thereof at the
option of the issuer  thereof,  the  principal of and the interest on which when
due,  without any regard to  reinvestment  thereof,  will provide  monies which,
together  with  money,  if any,  deposited  with  or  held  by the  Subordinated
Indenture Trustee or such Paying Agent, will be sufficient, or (c) a combination
of (a) and (b) which will be  sufficient,  to pay when due the  principal of and
premium,  if  any,  and  interest,  if  any,  due  and to  become  due  on  such
Subordinated  Debentures  or portions  thereof.  (Section 701) For this purpose,
unless otherwise  indicated in the applicable  Prospectus  Supplement,  Eligible
Obligations  include  direct  obligations  of,  or  obligations  unconditionally
guaranteed by, the United States,  entitled to the benefit of the full faith and
credit thereof, and certificates, depositary receipts or other instruments which
evidence a direct  ownership  interest in such  obligations  or in any  specific
interest or principal payments due in respect thereof. (Section 101)

<PAGE>

         While the Company knows of no legal  precedent on point, it is possible
that, for federal income tax purposes, any deposit contemplated in the preceding
paragraph could be treated as a taxable  exchange of the related  securities for
an issue of  obligations  of the  trust  or a  direct  interest  in the cash and
securities  held in the trust. In that case,  Holders of such  securities  would
recognize  gain or loss as if the trust  obligations  or the cash or  securities
deposited,  as the case may be, had actually  been  received by them in exchange
for their securities.  In addition, such Holders thereafter would be required to
recognize for federal income tax purposes a share of the income, gain or loss of
the trust.  The amount so required to be recognized  could be different from the
amount  that would be  recognized  in the absence of such  deposit.  Prospective
investors  are  urged to  consult  their  own tax  advisors  as to the  specific
consequences to them of any such deposit.

Resignation of Subordinated Indenture Trustee

         The  Subordinated  Indenture  Trustee  may resign at any time by giving
written  notice  thereof to the  Company or may be removed at any time by Act of
the Holders of a majority in principal  amount of  Subordinated  Debentures then
Outstanding delivered to the Subordinated  Indenture Trustee and the Company. No
resignation or removal of the Subordinated  Indenture Trustee and no appointment
of a successor trustee will become effective until the acceptance of appointment
by a successor  trustee in accordance with the  requirements of the Subordinated
Indenture.  So long as no Event of Default or event which, after notice or lapse
of  time,  or  both,  would  become  an Event of  Default  has  occurred  and is
continuing and except with respect to a Subordinated Indenture Trustee appointed
by Act of the  Holders  of a majority  in  principal  amount of the  Outstanding
Subordinated  Debentures,  if  the  Company  has  delivered  to  the  Trustee  a
resolution  of its Board of Directors  appointing  a successor  trustee and such
successor has accepted  such  appointment  in  accordance  with the terms of the
Subordinated  Indenture,  the Subordinated  Indenture  Trustee will be deemed to
have resigned and the successor will be deemed to have been appointed as trustee
in accordance with the Subordinated Indenture. (Section 910)

(Section 106)

Title

         The Company,  the Subordinated  Indenture Trustee, and any agent of the
Company or the Subordinated Indenture Trustee may treat the Person in whose name
a Subordinated Debenture is registered as the absolute owner thereof (whether or
not such  Subordinated  Debenture  may be  overdue)  for the  purpose  of making

Governing Law

         The  Subordinated  Indenture and the  Subordinated  Debentures  will be
governed by,  construed in accordance  with,  the laws of the State of New York,
except to the  extent  the law of any other  jurisdiction  shall be  mandatorily
applicable. (Section 112)

Limitation on Suits

         The  Subordinated  Indenture  limits a Holder's  right to institute any
proceeding  with respect to the  Subordinated  Indenture,  the  appointment of a
receiver or trustee,  or for any other remedy under the Subordinated  Indenture.
(Section 807)

Maintenance of Properties

         The Subordinated  Indenture  provides that the Company shall cause (or,
with respect to property owned in common with others,  make reasonable effort to
cause) all its  properties  used or useful in the conduct of its  business to be
maintained and kept in good condition,  repair and working order and shall cause
(or,  with  respect to property  owned in common with  others,  make  reasonable
effort to  cause)  to be made all  necessary  repairs,  renewals,  replacements,
betterments and  improvements  thereof,  all as, in the judgment of the Company,
may be necessary so that the business carried on in connection  therewith may be
properly conducted;  provided,  however,  that nothing shall prevent the Company
from  discontinuing,  or  causing  the  discontinuance  of,  the  operation  and
maintenance of any of its properties if such  discontinuance is, in the judgment
of the Company, desirable in the conduct of its business. (Section 605)

Modification of Senior Indebtedness

         In general,  the  holders of Senior  Indebtedness  may,  without in any
manner  affecting the  subordination of the payment of principal of and premium,
if any, and interest,  if any, on the Subordinated  Debentures in their absolute
discretion  agree  with the  Company  to change  the  manner,  place or terms of
payment,  change or extend the time of payment of, or renew or alter, any Senior
Indebtedness, or amend or supplement any instrument pursuant to which any Senior
Indebtedness  is issued,  or exercise or refrain  from  exercising  any other of
their rights under the Senior Indebtedness  including,  without limitation,  the
waiver of default  thereunder,  all without notice to or assent from the Holders
or the Trustee. (Section 1509)

Relationship with the Subordinated Indenture Trustee

         See "DESCRIPTION OF THE COLLATERAL TRUST BONDS -- Relationship with the
Trustee" for a description  of certain  relationships  between the  Subordinated
Indenture Trustee and the Company.

                                GLOBAL SECURITIES

         Some or all of the  Securities  of any  series may be  represented,  in
whole or in part, by one or more global securities  (each, a "Global  Security")
which will have an aggregate  principal  amount equal to that of the  Securities
represented  thereby.  Each Global  Security will be registered in the name of a
depositary (the  "Depositary") or a nominee thereof identified in the applicable
Prospectus  Supplement,  will be deposited with such  Depositary or nominee or a
custodian  therefor  and  will  bear a  legend  regarding  the  restrictions  on
exchanges and  registration of transfer  thereof  referred to below and any such
other  matters as may be provided for  pursuant to the Mortgage or  Subordinated
Indenture, as the case may be.

         As long as the Depositary,  or its nominee, is the registered holder of
a Global Security,  the Depositary or such nominee,  as the case may be, will be
considered the sole owner and holder of such Global  Security and the Securities
represented  thereby for all  purposes  under the  Mortgage or the  Subordinated
Indenture,  as the case may be.  Except  in  limited  circumstances,  owners  of
beneficial  interests  in a Global  Security  will not be  entitled to have such
Global Security or any Securities represented thereby registered in their names,
will not  receive or be entitled to receive  physical  delivery of  certificated
Securities  in exchange  therefor and will not be considered to be the owners or
holders of such Global  Security or any Securities  represented  thereby for any
purpose  under  the  Securities  or,  as the case may be,  the  Mortgage  or the
Subordinated  Indenture.  All  payments  of  principal  of and any  premium  and
interest on a Global Security will be made to the Depositary or its nominee,  as
the case may be, as the Holder thereof.  The laws of some jurisdictions  require
that certain  purchasers of securities take physical delivery of such securities
in  definitive  form.  These laws may impair the ability to transfer  beneficial
interests in a Global Security.

         Ownership of beneficial  interests in a Global Security will be limited
to  institutions   that  have  accounts  with  the  Depositary  or  its  nominee
(`participants")  and to  persons  that may hold  beneficial  interests  through
participants.  In  connection  with the  issuance  of any Global  Security,  the
Depositary will credit, on its book-entry  registration and transfer system, the
respective principal amounts of Securities represented by the Global Security to
the accounts of its participants.  Ownership of beneficial interests in a Global
Security  will be shown only on, and the transfer of those  ownership  interests
will be effected  only  through,  records  maintained  by the  Depositary  (with
respect to  participants'  interests) or any such  participant  (with respect to
interests  of persons  held by such  participants  on their  behalf).  Payments,
transfers,  exchanges,  and other matters relating to beneficial  interests in a
Global Security may be subject to various policies and procedures adopted by the
Depositary from time to time. None of the Company,  the Mortgage  Trustee or the
Subordinated  Indenture  Trustee,  or any agents of each of the foregoing,  will
have any  responsibility  or liability for any aspect of the Depositary's or any
participant's  records  relating  to,  or  for  payments  made  on  account  of,
beneficial interests in a Global Security, or for maintaining,  supervising,  or
reviewing any records relating to such beneficial interests.

                           Total....................................... $193,152
                                                                        ========

Item 15. Indemnification.

         Section 490.851 of the Iowa Business  Corporations  Act ("IBCA") grants
each  corporation  organized  thereunder,  such as the Registrant,  the power to
indemnify its directors and officers  against  liabilities  for certain of their
acts.  Section  6.1  of  the  Registrant's  Bylaws,  as  amended,  provides  for
indemnification  of directors and officers of the  Registrant to the full extent
permitted  by Section  490.851 of the IBCA.  Section  6.1 further  requires  the
Registrant to purchase and maintain  insurance on behalf of any person who is or
was a  director,  officer,  employee  or agent of the  Registrant,  or is or was
serving at the request of the  Registrant  as a director,  officer,  employee or
agent  of  another  corporation,  partnership,  joint  venture,  trust  or other
enterprise  against any liability  asserted and incurred  against such person in
any such capacity or arising out of such person's status as such, whether or not
the  Registrant  would have the power to  indemnify  such  person  against  such
liability under the provisions of Section 6.1. Section 2 of Article Ninth of the
Registrant's  Amended  Articles of  Incorporation,  however,  requires  that the
Registrant may, but is not required to, maintain such insurance.

         Section 490.832 of the IBCA grants corporations  organized  thereunder,
such as the Registrant,  the authority to adopt a provision in their  respective
articles of incorporation eliminating or limiting, with certain exceptions,  the
personal  liability of a director to the corporation or to its  shareholders for
monetary damages for certain breaches of fiduciary duty as a director. Section 1
of Article  Ninth of the Amended  Articles of  Incorporation  of the  Registrant
eliminates the personal  liability of each director except for liability (i) for
any  breach  of  the  director's  duty  of  loyalty  to  the  Registrant  or its
shareholders,  (ii) for acts or omissions not in good faith or which involve any
intentional  misconduct or knowing  violation of the law, (iii) any  transaction
from which the  director  derived an improper  personal  benefit,  or (iv) under
Section 490.833 of the IBCA relating to liability for unlawful distribution.

         The  foregoing  statements  are subject to the detailed  provisions  of
Sections 490.832,  490.833 and 490.851 of the IBCA, Article Ninth of the Amended
Articles of  Incorporation  of the Registrant and Section 6.1 of the Bylaws,  as
amended of the  Registrant,  as  applicable  and  should be read in  conjunction
therewith for a more full understanding of their affect on the Registrant.

         The  Registrant's  directors'  and  officers'  insurance  policies  are
designed to reimburse the Registrant for any payments made by it pursuant to the
foregoing indemnification provisions.

         The proposed form of underwriting  agreement for each of the Securities
contains  provisions  under  which  the  underwriters  agree  to  indemnify  the
directors and officers of the Registrant  against certain  liabilities under the
Securities Act of 1933, as amended (the "Act").

Item 16. Exhibits.

         See Exhibit Index on Page II - 6.

Item 17. Undertakings.

         The undersigned Registrant hereby undertakes:

         (1)      To file,  during any period in which offers or sales are being
made, a post-effective amendment to this Registration Statement:

                  (i)      To  include  any   prospectus   required  by  Section
         10(a)(3) of the Act;

                  (ii)     To  reflect  in the  prospectus  any  facts or events
         arising after the effective date of the Registration  Statement (or the
         most recent Post-Effective Amendment thereof) which, individually or in
         the aggregate,  represent a fundamental  change in the  information set
         forth in the Registration Statement. Notwithstanding the foregoing, any
         increase  or  decrease  in volume of  securities  offered (if the total
         dollar  value of  securities  offered  would not exceed  that which was
         registered) and any deviation from the low or high end of the estimated
         maximum offering range may be reflected in the form of prospectus filed
         with the Commission  pursuant to Rule 424(b) if, in the aggregate,  the
         changes in volume and price  represent no more than a 20% change in the
         maximum  aggregate  offering  price  set forth in the  "Calculation  of
         Registration Fee" table in the effective registration statement;

                  (iii)    To include any material  information  with respect to
         the plan of distribution  not previously  disclosed in the Registration
         Statement  or  any  material   change  to  such   information   in  the
         Registration Statement;

Provided,  however,  that  paragraphs  (1)(i)  and  (1)(ii)  do not apply if the
Registration Statement is on Form S-3, or Form S-8, and the information required
to be included in a Post-Effective Amendment by those paragraphs is contained in
periodic  reports  filed  with  or  furnished  to the  Securities  and  Exchange
Commission  by the  Registrant  pursuant  to Section 13 or Section  15(d) of the
Securities  Exchange  Act of 1934,  as  amended  (the  "Exchange  Act") that are
incorporated by reference in the Registration Statement.

         (2)      That, for the purpose of determining  liability under the Act,
each such  Post-Effective  Amendment  shall be  deemed to be a new  Registration
Statement  relating to the securities  offered  therein and the offering of such
securities  at that time shall be deemed to be the  initial  bona fide  offering
thereof.

         (3)      To  remove  from  registration  by means  of a  Post-Effective
Amendment any of the  securities  which remain unsold at the  termination of the
offering.

         (4)      That for purposes of determining  any liability under the Act,
each filing of the Registrant's annual report pursuant to Section 13(a) or 15(d)
of the Exchange Act (and, where  applicable,  each filing of an employee benefit
plan's  annual  report  pursuant to Section  15(d) of the Exchange  Act) that is
incorporated by reference in the Registration  Statement shall be deemed to be a
new Registration  Statement  relating to the securities  offered therein and the
offering of such  securities at that time shall be deemed to be the initial bona
fide offering thereof.


                                     II - 2


<PAGE>


         Insofar as  indemnification  for liabilities  arising under the Act, as
amended, may be permitted to directors, officers, and controlling persons of the
Registrant pursuant to the foregoing  provisions,  or otherwise,  the Registrant
has been advised that in the opinion of the Securities  and Exchange  Commission
such  indemnification  is against  public policy as expressed in the Act and is,
therefore,  unenforceable. In the event that a claim for indemnification against
such liabilities  (other than the payment by the Registrant of expenses incurred
or paid by a director,  officer or  controlling  person of the Registrant in the
successful  defense of any  action,  suit or  proceeding)  is  asserted  by such
director,  officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

                  SECTION   1.   Purchase   and  Sale.   On  the  basis  of  the
representations  and warranties,  and subject to the terms and  conditions,  set

below) shall  purchase from IES Utilities  Inc.  ("Company"),  severally and not
jointly, and the Company shall sell to each of the Underwriters (defined below),
the principal amount of the Company's  Collateral Trust Bonds set forth opposite
the name of such  Underwriter  in Schedule II hereto at the price  specified  in
Schedule I hereto,  plus  accrued  interest,  if any, at the rate  specified  in
Schedule I hereto. The aggregate principal amount of such Collateral Trust Bonds
being sold hereunder is hereinafter referred to as the "Bonds."

                  SECTION  2.   Underwriters   and   Representative.   The  term
"Underwriters,"  as used  herein,  shall be deemed to mean the several  persons,
firms,  or corporations  named in Schedule II hereto  (including any substituted
Underwriters under the provisions of Section 6), and the term  "Representative,"
as used herein, shall be deemed to mean the representative or representatives of
such  Underwriters  by whom or on whose  behalf this  Underwriting  Agreement is
signed.  If there  shall  be one  person,  firm,  or  corporation  named in said
Schedule  II, the term  "Underwriters"  and the term  "Representative,"  as used
herein,  shall mean that person,  firm, or  corporation.  All obligations of the
Underwriters are several and not joint. The use of the term "Underwriter" herein

Securities Act of 1933, as amended ("Securities Act").

                  SECTION 3. Description of the Bonds. The Bonds shall be in the
aggregate  principal amount and shall mature on the date specified in Schedule I
hereto,  and shall be issued under and secured by the  Indenture of Mortgage and
Deed of Trust,  dated as of  September  1,  1993,  of the  Company  to The First
National  Bank of  Chicago  as  Trustee  ("Trustee"),  as  supplemented  by ____

indenture  ("Supplemental  Indenture")  relating to the Bonds. Said Indenture of
Mortgage and Deed of Trust, as so  supplemented,  is hereinafter  referred to as
the "Mortgage". The Bonds shall bear interest at the rate per annum specified in
Schedule I hereto.  The Bonds and the Mortgage  are more fully  described in the
Prospectus hereinafter referred to.

                  SECTION 4.  Representations  and Warranties of the Company.  
The Company  represents and warrants that:

          (a)  It  has  filed  with  the  Securities  and  Exchange   Commission
     ("Commission")   two  registration   statements  (File  Nos.  33-62259  and
     333-_____)   (collectively,   the   "Registration   Statement")   for   the
     registration of up to an aggregate of $135,000,000  principal amount of the
     Company's debt securities under the Securities Act. Registration statements
     (File Nos.  33-62259 and 333-_____)  have become  effective.  No stop order
     suspending the effectiveness of the Registration Statement has been issued,
     and no  proceedings  for that purpose have been  initiated or threatened by
     the Commission. The prospectus (including the supplement thereto) forming a
     part of the  Registration  Statement,  at that time  pursuant to Item 12 of
     Form S-3,  is  hereinafter  referred to as the "Basic  Prospectus."  In the
     event  that the Basic  Prospectus  shall  have been  amended,  revised,  or
     supplemented  (but excluding any amendments,  revisions,  or supplements to
     the Basic  Prospectus  relating  solely to the offering of debt  securities
     other  than  the  Bonds)  prior  to  the  time  of  effectiveness  of  this
     Underwriting  Agreement,  and with  respect to any  documents  filed by the
     Company pursuant to Section 13, 14, or 15(d) of the Securities Exchange Act
     of 1934,  as  amended  ("Exchange  Act"),  after the time the  Registration
     Statement initially became effective and up to the time of effectiveness of
     this Underwriting  Agreement (but excluding documents  incorporated therein
     by reference  relating solely to the offering of debt securities other than
     the Bonds),  which  documents are deemed to be incorporated by reference in
     the Basic Prospectus, the term "Basic Prospectus" as used herein shall also
     mean  such  prospectus  as  so  amended,  revised,  or  supplemented.   The
     Registration  Statement as it initially became effective and as it may have
     been amended by any amendment thereto  incorporated in the Basic Prospectus
     (including for these purposes as an amendment any document  incorporated by
     reference in the Basic  Prospectus) and the Basic Prospectus as it shall be
     supplemented  to reflect the terms of  offering  and sale of the Bonds by a
     prospectus  supplement  ("Prospectus  Supplement")  to be  filed  with  the
     Commission  pursuant to Rule 424 under the Securities Act ("Rule 424"), are
     hereinafter   referred  to  as  the   "Registration   Statement"   and  the
     "Prospectus," respectively;

          (b) After the time of  effectiveness of this  Underwriting  Agreement,
     the Company will not file (i) any amendment to the  Registration  Statement
     (except any amendment  relating  solely to the offering of debt  securities
     other than the Bonds) or supplement to the  Prospectus or (ii) prior to the
     time that the Prospectus is filed with the Commission pursuant to Rule 424,
     any document which is to be incorporated by reference in, or any supplement
     (including the Prospectus  Supplement) to, the Basic Prospectus,  in either
     case without  prior notice to the  Representative  and Dorsey & Whitney LLP
     ("Counsel for the  Underwriters"),  or any such amendment,  supplement,  or
     document to which said Counsel shall reasonably  object on legal grounds in
     writing.  For purposes of this Underwriting  Agreement,  any document filed
     with the Commission after the effectiveness of this Underwriting  Agreement
     and  incorporated  by  reference  in  the  Prospectus   (except   documents
     incorporated  by  reference   relating  solely  to  the  offering  of  debt

     the applicable provisions of the Securities Act, the Trust Indenture Act of

     or, if later than such dates,  on the date that the  Company's  most recent
     annual report on Form 10-K was filed with the Commission under the Exchange

     statement of a material  fact or omit to state a material  fact required to
     be  stated  therein  or  necessary  to  make  the  statements  therein  not
     misleading;  the  Prospectus,  at the date it is filed with the  Commission
     pursuant to Rule 424 and at the Closing Date (hereinafter  defined),  as it
     may be amended or  supplemented,  will not include an untrue statement of a
     material fact or omit to state a material  fact  necessary in order to make
     the statements  therein, in the light of the circumstances under which they
     are  made,  not  misleading;  and on  said  dates  and at such  times,  the
     documents then incorporated by reference in the Prospectus pursuant to Item
     12 of Form S-3, when read together with the  Prospectus,  or the Prospectus
     as it may then be  amended  or  supplemented,  will not  contain  an untrue

     indenture or other  agreement or  instrument  to which the Company is now a
     party,  including  the  Agreement  and  Plan of  Merger  by and  among  WPL
     Holdings, Inc., IES Industries Inc., and Interstate Power Company, dated as
     of November 10, 1995, as amended.

                  SECTION 5.  Offering.  Forthwith  upon the  execution  of this
Underwriting   Agreement,   the   Representative,   acting   on  behalf  of  the
Underwriters, shall advise the Company whether a public offering of the Bonds is
to be made, and, if so, shall furnish to the Company (which information shall be
confirmed in writing as soon as practicable thereafter) (a) the information with
respect to such  offering of the Bonds and related  matters  that is required to
complete  the  Prospectus  Supplement  or any  post-effective  amendment  to the
Registration  Statement which may be required and a copy of any "agreement among
underwriters";  (b) if a post-effective  amendment to the Registration Statement
is  required,  a consent,  if  necessary,  to the  filing of the  post-effective
amendment or an acceptable power-of-attorney authorizing an available individual
to sign the consent on its behalf; and (c) such further information,  if any, as
may be required to be furnished by the Company under the Federal Power Act. Such
information and the power-of-attorney may be provided by telecopier (in the case
of the  power-of-attorney,  followed  promptly by an executed copy).  Nothing in
this Underwriting  Agreement shall be construed to require that the Underwriters
make any such  public  offering on a "fixed  price"  basis.  The  Representative
agrees  to  notify  the  Company  in  writing  of  any  change  in the  plan  of
distribution  of the Bonds that would require a supplement to the  Prospectus or
an amendment to the Registration Statement.

                  SECTION 6. Time and Place of  Closing.  Delivery  of the Bonds
and payment therefor by check or checks, payable to the Company or its order, in
New York, New York, or by wire transfer,  in immediately  available funds, shall
be made at the offices of Winthrop,  Stimson, Putnam & Roberts, One Battery Park
Plaza,  New York, New York, at 10:00 A.M.,  New York time, on __________,  or at
such other place,  time, and/or date as the  Representative  and the Company may
agree upon in writing or as may be established in accordance  with the following
paragraph.  The hour and date of such delivery and payment are herein called the
"Closing Date."

                  The Bonds shall be  delivered  to the  Representative  for the
respective  accounts of the  Underwriters  in registered form in such authorized
denominations and registered in such names as the  Representative may reasonably
request in writing at least two business days prior to the Closing Date,  or, to
the extent not so requested, in the names of the respective Underwriters in such
denominations as the Company shall determine.

                  For the purpose of expediting the checking of the Bonds by the
Representative,   the  Company  agrees  to  make  the  Bonds  available  to  the
Representative for checking not later than 2:30 P.M., New York time, on the last
business day  preceding  the Closing  Date,  at the New York office of The First
National Bank of Chicago,  or at such other place,  time,  and/or date as may be
agreed upon between the Company and the Representative.

                  If any  Underwriter  shall fail or refuse  (otherwise than for
some reason  sufficient  to justify,  in accordance  with the terms hereof,  the
cancellation  or termination of its  obligations  hereunder) to purchase and pay
for the  principal  amount of Bonds that it has agreed to  purchase  and pay for
hereunder,  the Company shall  immediately give notice to the  Representative of
the default of such Underwriter, and the other Underwriters shall have the right
within  twenty-four  (24)  hours  after  the  receipt  of  such  notice  by  the
Representative to determine to purchase,  or to procure one or more others,  who
are members of the National  Association of Securities  Dealers,  Inc.  ("NASD")
(or, if not members of the NASD, who are foreign banks, dealers, or institutions
not  registered  under the  Exchange Act and who agree in making sales to comply
with the NASD's Rules of Fair Practice),  and  satisfactory  to the Company,  to
purchase,  upon the terms herein set forth,  the principal  amount of Bonds that
the  defaulting  Underwriter  had  agreed  to  purchase.  If any  non-defaulting
Underwriter  or  Underwriters  shall  determine  to  exercise  such  right,  the
Representative  shall give written  notice to the Company of such  determination
within  twenty-four  (24) hours after it shall have received  notice of any such
default,  and thereupon the Closing Date shall be postponed for such period, not
exceeding three business days, as the Company shall  determine.  If in the event
of such a default the  Representative  shall fail to give such notice,  or shall
within such twenty-four (24) hour period give written notice to the Company that
no other Underwriter or Underwriters,  or others, will exercise such right, then
this Underwriting  Agreement may be terminated by the Company,  upon like notice
given to the Representative,  within a further period of twenty-four (24) hours.
If in such  case the  Company  shall not elect to  terminate  this  Underwriting
Agreement, it shall have the right, irrespective of such default:

          (a) to require such  non-defaulting  Underwriters  to purchase and pay
     for the  respective  principal  amounts  of Bonds  that they had  severally
     agreed to purchase hereunder,  as hereinabove  provided,  and, in addition,
     the principal amount of Bonds that the defaulting Underwriter shall have so
     failed to purchase  up to a principal  amount  thereof  equal to  one-ninth
     (1/9th)   of  the   respective   principal   amounts  of  Bonds  that  such
     non-defaulting  Underwriters  have otherwise agreed to purchase  hereunder,
     and/or

          (b) to procure one or more others, who are members of the NASD (or, if
     not members of the NASD, who are foreign banks,  dealers,  or  institutions
     not  registered  under the  Exchange  Act and who agree in making  sales to
     comply with the NASD's Rules of Fair Practice), to purchase, upon the terms
     herein  set  forth,  the  principal  amount of Bonds  that such  defaulting
     Underwriter  had  agreed to  purchase,  or that  portion  thereof  that the
     remaining  Underwriters  shall not be obligated to purchase pursuant to the
     foregoing clause (a).

In the event the Company  shall  exercise its rights under clause (a) and/or (b)
above,  the Company  shall give  written  notice  thereof to the  Representative
within such  further  period of  twenty-four  (24) hours,  and,  thereupon,  the
Closing Date shall be postponed for such period,  not exceeding  three  business
days, as the Company shall determine. In the event the Company shall be entitled
to but shall not elect to exercise  its rights  under clause (a) and/or (b), the
Company  shall  be  deemed  to  have  elected  to  terminate  this  Underwriting
Agreement.

                  Any action taken by the Company under this Section 6 shall not
relieve any defaulting  Underwriter  from liability in respect of any default of
such Underwriter under this Underwriting  Agreement.  Termination by the Company
under this  Section 6 shall be without any  liability on the part of the Company
or any  non-defaulting  Underwriter,  except as otherwise provided in subsection
(g) of Section 7.

                  In the  computation  of any period of  twenty-four  (24) hours
referred to in this  Section 6, there shall be excluded a period of  twenty-four
(24) hours in respect of each  Saturday,  Sunday,  or legal  holiday which would
otherwise be included in such period of time.

                  SECTION 7.  Covenants of the Company.  The Company agrees with
each of the Underwriters:

          (a) To deliver to the Representative a signed copy of the Registration
     Statement as originally filed and of all amendments thereto relating to the
     Bonds or a conformed copy thereof certified by an officer of the Company to
     be in the form filed.

          (b) To deliver to the Underwriters, through the Representative,  prior
     to 10:00  A.M.  New York time on the  business  day after the date on which
     this  Underwriting  Agreement  becomes  effective  as  many  copies  of the
     Prospectus as the Representative may reasonably request.

          (c) To cause the Prospectus to be filed with the  Commission  pursuant
     to and in  compliance  with Rule  424,  and to  advise  the  Representative
     promptly of the  issuance of any stop order under the  Securities  Act with
     respect to the Registration Statement or the institution of any proceedings
     therefor of which the Company shall have received notice.  The Company will
     use its best  efforts to prevent the issuance of any such stop order and to
     secure the prompt removal thereof if issued.

          (d) During such period of time (not  exceeding  nine months) after the
     Prospectus has been filed with the  Commission  pursuant to Rule 424 as the
     Underwriters  are  required  by law to deliver a  prospectus,  if any event
     relating  to or  affecting  the  Company or of which the  Company  shall be
     advised in writing by the Representative shall occur which in the Company's
     opinion  should be set forth in a supplement or amendment to the Prospectus
     in order to make the statements  therein, in the light of the circumstances
     when  the  Prospectus  is  delivered  to a  purchaser  of  the  Bonds,  not
     misleading,  to notify  the  Representative  of such  event and to amend or
     supplement  the  Prospectus  by either (i)  preparing  and filing  with the
     Commission and furnishing to the  Representative at the Company's expense a
     reasonable  number of copies of a supplement or supplements or an amendment
     or  amendments  to the  Prospectus  or (ii)  making an  appropriate  filing
     pursuant  to  Section  13,  14, or 15(d) of the  Exchange  Act,  which will
     supplement or amend the Prospectus so that, as supplemented or amended,  it
     will not contain an untrue  statement of a material fact or omit to state a
     material fact  required to be stated  therein or necessary in order to make
     the  statements  therein,  in the  light  of  the  circumstances  when  the
     Prospectus  is  delivered  to a  purchaser  of the Bonds,  not  misleading;
     provided that should such event relate  solely to the  activities of any of
     the  Underwriters,  then the  Underwriters  shall  assume  the  expense  of
     preparing any such  amendment or  supplement.  In case any  Underwriter  is
     required to deliver a prospectus  after the  expiration of nine months from
     the date the Prospectus is filed with the Commission  pursuant to Rule 424,
     the Company,  upon the request of the  Representative,  will furnish to the
     Representative,  at the expense of such Underwriter,  a reasonable quantity
     of a supplemented or amended prospectus or supplements or amendments to the
     Prospectus complying with Section 10(a) of the Securities Act.

          (e) During such period of time after the date the  Prospectus is filed
     with the  Commission  pursuant to Rule 424 as a prospectus  relating to the
     Bonds is  required  to be  delivered  under  the  Securities  Act,  to file
     promptly all documents required to be filed with the Commission pursuant to
     Section 13, 14, or 15(d) of the Exchange Act.

          (f) To make generally  available to the Company's  security holders as
     soon as  practicable  an earning  statement  (which need not be audited) in
     reasonable  detail  covering a period of at least twelve  months  beginning
     after the "effective date of the registration statement" within the meaning
     of Rule 158 under the Securities  Act, which earning  statement shall be in
     such form,  and be made generally  available to security  holders in such a
     manner,  as to  comply  with  the  requirements  of  Section  11(a)  of the
     Securities Act and Rule 158 promulgated under the Securities Act.

          (g) Except as herein otherwise provided, to pay all expenses and taxes
     (except  transfer  taxes) in connection with (i) the preparation and filing
     of  the  Registration  Statement  and  any  amendments  thereto,  (ii)  the
     issuance,  printing,  and  delivery  of the Bonds,  (iii) the  preparation,
     execution,  filing, and recording of the Supplemental  Indenture,  (iv) any
     fees charged by securities rating services for rating the Bonds and (v) the
     typing,   printing,   and  delivery  to  the   Underwriters,   through  the
     Representative,  of  reasonable  quantities  of copies of the  Registration
     Statement and the  Prospectus,  and any  amendment or  supplement  thereto,
     except as otherwise provided in paragraph (d) of this Section.  The Company
     shall not,  however,  be required to pay any amount for any expenses of the
     Representative   or  any  of  the   Underwriters,   except  that,  if  this
     Underwriting   Agreement   shall  be  terminated  in  accordance  with  the
     provisions  of  Section  8,  9,  or 11,  the  Company  will  reimburse  the
     Representative for (i) the reasonable fees and disbursements of counsel for
     the Underwriters,  whose fees and  disbursements the Underwriters  agree to
     pay in any other event, and (ii) their reasonable  out-of-pocket  expenses,
     in an amount  not  exceeding  a total of ten  thousand  dollars  ($10,000),
     incurred  in  contemplation   of  the  performance  of  this   Underwriting
     Agreement.  The  Company  shall  not in any  event be  liable to any of the
     Underwriters for damages on account of loss of anticipated profits.

          (h) Not to sell any  additional  Collateral  Trust  Bonds  (other than
     Collateral  Trust  Bonds  of  one or  more  series  having  a  maturity  or
     maturities  different  from the date of maturity of the Bonds)  without the
     consent of the Representative until the earlier to occur of (i) the Closing
     Date or (ii) in the case of an initial public  offering at a fixed price by
     the  Underwriters,  the date of the termination of the fixed price offering
     restrictions  applicable to the Underwriters.  The Representative agrees to
     notify the Company of such  termination  if it occurs  prior to the Closing
     Date.

                  SECTION  8.  Conditions  of  Underwriters'  Obligations.   The
obligation  of the  Underwriters  to  purchase  and pay for the  Bonds  shall be

     Statement  shall  be in  effect  at or prior to the  Closing  Date,  and no
     proceedings for that purpose shall be pending before, or threatened by, the
     Commission on the Closing Date.

          (c) The authorization by the Federal Energy  Regulatory  Commission of
     the issuance and sale of the Bonds shall be in full force and effect.

                  In case any of the  conditions  specified  in this  Section  9
shall not have been fulfilled,  this Underwriting Agreement may be terminated by
the Company  upon notice  thereof to the  Representative.  Any such  termination
shall be without liability of any party to any other party,  except as otherwise
provided in subsection (g) of Section 7.

                  SECTION 10.  Indemnification.

          (a) The  Company  shall  indemnify,  defend,  and hold  harmless  each
     Underwriter and each person who controls any Underwriter within the meaning
     of Section 15 of the  Securities  Act from and  against any and all losses,
     claims, damages, or liabilities,  joint or several, to which they or any of
     them may become  subject under the  Securities  Act or any other statute or
     common  law.  The  Company  shall  reimburse  each  such   Underwriter  and
     controlling  person  for any  legal or other  expenses  (including,  to the
     extent  hereinafter  provided,  reasonable  counsel fees) incurred by them,
     such  reimbursement  to be made as such  expenses are incurred by them,  in
     connection  with  investigating  any  such  losses,  claims,   damages,  or
     liabilities or in connection  with  defending any actions,  insofar as such
     losses, claims, damages, liabilities,  expenses, or actions arise out of or
     are based  upon any  untrue  statement  or alleged  untrue  statement  of a
     material fact  contained in a preliminary  prospectus (if used prior to the
     initial  effective  date of the  Registration  Statement),  or in the Basic
     Prospectus (if used prior to the date that the Prospectus is filed with the
     Commission  pursuant to Rule 424) or in the  Registration  Statement or the
     Prospectus,  as amended or  supplemented  (if any amendments or supplements
     thereto shall have been made), or the omission or alleged omission to state
     therein a material fact required to be stated  therein or necessary to make
     the statements therein, in light of the circumstances under which they were
     made,  not  misleading;  provided,  however,  that the indemnity  agreement
     contained in this  paragraph  shall not apply to any such  losses,  claims,
     damages,  liabilities,  expenses, or actions arising out of, or based upon,
     any such untrue statement or alleged untrue statement, or any such omission
     or alleged  omission,  if such  statement  or omission was made in reliance
     upon and in conformity with written information furnished to the Company by
     or through the  Representative  on behalf of any Underwriter  expressly for
     use in connection with the preparation of the Registration Statement or the
     Prospectus or any amendment or supplement to either thereof, or arising out
     of,  or based  upon,  statements  in or  omissions  from  that  part of the
     Registration  Statement which shall constitute the statement of eligibility
     under the Trust  Indenture  Act of the  Trustee  under the  Indenture;  and
     provided further,  that the indemnity agreement contained in this paragraph
     shall  not  inure  to the  benefit  of  any  Underwriter  or of any  person
     controlling any Underwriter on account of any such losses, claims, damages,
     liabilities, expenses, or actions arising from the sale of the Bonds to any
     person if there  shall not have been given or sent to such person on behalf
     of such  Underwriter  (i) with or prior to the written  confirmation of the
     sale  to  such  person  a copy  of  the  Prospectus,  as  then  amended  or
     supplemented  (exclusive  for this purpose of any  amendment or  supplement
     relating solely to any offering of debt securities other than the Bonds and
     of any document which becomes incorporated by reference pursuant to Item 12
     of Form S-3 more than 3 business days prior to the date  hereof),  and (ii)
     as  soon  as  available  after  such  written  confirmation  a copy  of any
     amendment or supplement to the  Prospectus  (exclusive  for this purpose of
     any document  incorporated  by  reference  pursuant to Item 12 of Form S-3)
     which the Company shall thereafter  furnish,  pursuant to subsection (d) of
     Section 7 hereof,  relating to an event  occurring prior to the payment for
     and  delivery  to such  person  of the Bonds  involved  in such  sale.  The
     indemnity  agreement  of the  Company  contained  in this  Section  and the
     representations  and warranties of the Company contained in Section 4 shall
     remain   operative  and  in  full  force  and  effect   regardless  of  any
     investigation  made  by or  on  behalf  of  any  Underwriter  or  any  such
     controlling person, and shall survive the delivery of the Bonds.

          (b) Each Underwriter  shall indemnify,  defend,  and hold harmless the
     Company,  its directors  and officers,  and each person who controls any of
     the foregoing  within the meaning of Section 15 of the Securities Act, from
     and against any and all losses, claims,  damages, or liabilities,  joint or
     several,  to  which  they or any of  them  may  become  subject  under  the
     Securities Act or any other statute or common law and shall  reimburse each
     of  them  for  any  legal  or  other  expenses  (including,  to the  extent
     hereinafter  provided,  reasonable  counsel  fees)  incurred by them,  such
     reimbursement  to be  made  as such  expenses  are  incurred  by  them,  in
     connection  with  investigating  any  such  losses,  claims,   damages,  or
     liabilities  or in connection  with  defending any action,  insofar as such
     losses, claims, damages, liabilities,  expenses, or actions arise out of or
     are based  upon any  untrue  statement  or alleged  untrue  statement  of a
     material fact contained in the Registration Statement or the Prospectus, as
     amended or  supplemented  (if any amendments or  supplements  thereto shall
     have been furnished),  or the omission or alleged omission to state therein
     a material  fact  required to be stated  therein or  necessary  to make the
     statements  therein not misleading,  if such statement or omission was made
     in reliance upon and in conformity  with written  information  furnished to
     the Company by or through the  Representative on behalf of such Underwriter
     expressly for use in connection  with the  preparation of the  Registration
     Statement  or the  Prospectus  or any  amendment  or  supplement  to either
     thereof. The indemnity agreement of the respective  Underwriters  contained
     in this  paragraph  shall  remain  operative  and in full  force and effect
     regardless of any  investigation  made by or on behalf of the Company,  its
     directors or officers,  or any such controlling  person,  and shall survive
     the delivery of the Bonds.

          (c) The  Company  and the several  Underwriters  each shall,  upon the
     receipt  of notice of the  commencement  of any  action  against  it or any
     person  controlling it as aforesaid,  in respect of which  indemnity may be
     sought on account of any indemnity  agreement  contained  herein,  promptly
     give  written  notice of the  commencement  thereof to the party or parties
     against whom indemnity  shall be sought  hereunder,  but the omission so to
     notify  the  indemnifying  party or parties  of any such  action  shall not
     relieve the  indemnifying  party or parties from any liability  which it or
     they may have to the  indemnified  party  otherwise than on account of such
     indemnity  agreement.  In case such notice of any such  action  shall be so
     given, the  indemnifying  party shall be entitled to participate at its own
     expense in the defense or, if it so elects,  to assume (in conjunction with
     any other  indemnifying  parties) the defense of the action, in which event
     the defense shall be conducted by counsel chosen by such indemnifying party
     or parties and  satisfactory to the indemnified  party or parties who shall
     be a defendant or defendants in the action,  and the indemnified  defendant
     or defendants  shall bear the fees and expenses of any  additional  counsel
     retained by them; but if the  indemnifying  party shall elect not to assume
     the  defense of the  action,  the  indemnifying  party will  reimburse  the
     indemnified  party or parties for the  reasonable  fees and expenses of any
     counsel retained by the indemnified  party or parties.  If the indemnifying
     party does not employ  counsel to take  charge of the defense or if counsel
     for the indemnifying party reasonably  concludes that there may be defenses
     available to the indemnified  party which are different from or in addition
     to  those  available  to  the   indemnifying   party  (in  which  case  the
     indemnifying  party will not have the right to assume the defense on behalf
     of the indemnified party),  legal expenses (limited to those of one counsel
     for all indemnified  parties) and other expenses reasonably incurred by the
     indemnified party will be paid by the indemnifying  party. No party will be
     liable  with  respect to any  settlement  made  without  its prior  written
     consent.

          (d)  If  the  indemnification  provided  for  in  this  Section  10 is
     unavailable to hold harmless an indemnified  party under  subsection (a) or
     (b) above in respect of any  losses,  claims,  damages or  liabilities  (or
     actions in respect  thereof)  referred to therein,  then each  indemnifying
     party shall  contribute  to the amount paid or payable by such  indemnified
     party as a result  of such  losses,  claims,  damages  or  liabilities  (or
     actions in respect thereof) in such proportion as is appropriate to reflect
     the relative fault of the Company on the one hand and the  Underwriters  on
     the other in connection  with the statements or omissions which resulted in
     such losses, claims, damages or liabilities (or actions in respect thereof)
     as well as any other relevant equitable considerations.  The relative fault
     shall be determined by reference to, among other things, whether the untrue
     or alleged untrue  statements of a material fact or the omission or alleged
     omission to state a material  fact relates to  information  supplied by the
     Company on the one hand or the  Underwriters  on the other and the parties'
     relative  intent,  knowledge,  access to  information  and  opportunity  to
     correct or  prevent  such  statements  or  omission.  The  Company  and the
     Underwriters  agree that it would not be just and equitable if contribution
     pursuant to this  subsection  (d) were  determined  by pro rata  allocation
     (even if the  Underwriters  were treated as one entity for such purpose) or
     by any other method of allocation  which does not take account of equitable
     considerations referred to above in this subsection (d). The amount paid or
     payable by an indemnified party as a result of the losses,  claims, damages
     or liabilities  (or actions in respect  thereof)  referred to above in this
     subsection  (d)  shall be  deemed to  include  any legal or other  expenses
     reasonably   incurred  by  such   indemnified   party  in  connection  with
     investigating  or defending any such action or claim.  Notwithstanding  the
     provisions  of this  subsection  (d), no  Underwriter  shall be required to
     contribute  any amount in excess of the amount by which the total  price at
     which the Bonds  underwritten  by it and  distributed  to the  public  were
     offered  to the  public  exceeds  the  amount  of any  damages  which  such
     Underwriter  has otherwise been required to pay by reason of such untrue or
     alleged untrue statement or omission or alleged omission.  No person guilty
     of fraudulent misrepresentation (within the meaning of Section 11(f) of the
     Securities Act) shall be entitled to  contribution  from any person who was
     not  guilty  of  such  fraudulent   misrepresentation.   The  Underwriters'
     obligations in this  subsection (d) to contribute are several in proportion
     to their respective underwriting obligations and not joint.

          (e) The  respective  obligations  of the Company and the  Underwriters
     under this Section 10 shall be in addition to any  liability  which each of
     them may otherwise have.

                  SECTION 11.  Termination.  This Underwriting  Agreement may be
terminated at any time prior to the Closing Date by the Representative  with the
consent of the  Underwriters,  who may  include the  Representative,  which have
agreed to purchase in the aggregate fifty percent (50%) or more of the aggregate
principal amount of the Bonds, if, prior to such time, (i) trading in securities
on the New York Stock Exchange shall have been generally suspended, (ii) minimum
or maximum  ranges for prices shall have been  generally  established on the New
York Stock Exchange by the New York Stock  Exchange,  the  Commission,  or other
governmental  authority,  (iii) a general  banking  moratorium  shall  have been
declared  by  federal  or New  York  State  authorities,  (iv)  an  outbreak  or
escalation of hostilities or other national or international  calamity or crisis
occurs,  the effect of which on the  financial  markets of the United  States is
such  as,  in  the  reasonable  judgment  of  the  Representative,  to  make  it
impracticable to market the Bonds or enforce contracts for the sale of the Bonds
or (v) in the reasonable judgment of the  Representative,  the subject matter of
any amendment or supplement  (prepared by the Company) to the Basic  Prospectus,
the Registration Statement or the Prospectus (except for information relating to
the  public  offering  of the Bonds or to the  activity  of any  Underwriter  or
Underwriters)  filed or issued  after  the  effectiveness  of this  Underwriting
Agreement by the Company shall have materially impaired the marketability of the
Bonds.  Any  termination  hereof  pursuant  to this  Section 11 shall be without
liability  of any party to any other  party,  except as  otherwise  provided  in
subsection (g) of Section 7.

                  SECTION 12.  Applicable Law. This  Underwriting  Agreement and
the Bonds to be sold hereunder shall be New York  contracts,  and their validity
and interpretation shall be governed by the laws of the State of New York.

                  SECTION 13.  Successors.  This  Underwriting  Agreement  shall
inure to the benefit of the Company,  the Underwriters  and, with respect to the
provisions  of Section  10,  each  director,  officer,  and  controlling  person
referred to in Section 10, and their  respective  successors.  Nothing herein is
intended or shall be construed to give to any other person, firm, or corporation
any legal or  equitable  right,  remedy,  or claim  under or in  respect  of any
provision in this Underwriting  Agreement.  The term "successor" as used in this
Underwriting  Agreement shall not include any purchaser,  as such purchaser,  of
any of the Bonds from any of the Underwriters.

                  SECTION  14.  Notices.  All communications hereunder shall  be
in writing  and, if to the  Underwriters,  shall be mailed or  delivered  to the
Representative  at the address set forth below, or, if to the Company,  shall be
mailed or delivered to it c/o IES Utilities Inc., 200 First Street,  S.E., Cedar
Rapids, Iowa 52401 Attention: Treasurer.

                  SECTION 15. Counterparts.  This Underwriting  Agreement may be
executed  in any  number of  counterparts  and by  different  parties  hereto on
separate  counterparts,   each  of  such  counterparts,  when  so  executed  and
delivered,  shall be  deemed  to be an  original,  and all of such  counterparts
shall, taken together, constitute one and the same agreement.

Re:  $__________ Collateral Trust Bonds ___% Series Due ____

Ladies and Gentlemen:

                  I am counsel for IES  Industries  Inc.,  the parent company of
IES Utilities  Inc. (the  "Company") and have  participated  in the issuance and
sale  by the  Company  to you  of  $__________  aggregate  principal  amount  of
Collateral  Trust Bonds ___%  Series Due ____ (the  "Bonds"),  issued  under the
Company's  Indenture  of Mortgage  and Deed of Trust,  dated as of  September 1,
1993, to The First  National  Bank of Chicago,  as Trustee (the  "Trustee"),  as
heretofore  supplemented and as supplemented by the _____ Supplemental Indenture
dated  as  of  __________  (the  "Supplemental  Indenture")  (said  Mortgage  of
Indenture  and Deed of Trust as so  supplemented  is herein  referred  to as the
"Mortgage") pursuant to an Underwriting Agreement dated as of __________ between
you and the Company (the "Underwriting Agreement").

                  In  this   connection,   I,  or  attorneys  under  my  general
supervision, have examined, among other things, the following:

                    (a) the  Registration  Statement  and the  Prospectus  (such
               terms  having  the same  meanings  herein as in the  Underwriting
               Agreement);

                    (b) the  Articles  of  Incorporation  of the Company and all
               amendments thereto, as certified by the Secretary of State of the
               State of Iowa;

                    (c) a  Certificate  of  the  Secretary  of  State  or  other
               appropriate state official certifying as to the good standing and
               qualification of the Company to transact business in the State of
               Iowa;

                    (d) the By-laws of the Company,  certified by the  Secretary
               of the Company;

                    (e) the Mortgage;

                    (f) the  Company's  Indenture  of Mortgage and Deed of Trust
               dated  as of  August  1,  1940,  to The  First  National  Bank of
               Chicago,  as trustee,  as amended and  supplemented  and as it is
               further supplemented by the _____ Supplemental  Indenture,  dated
               as of __________ (the "1940 Supplemental Indenture"), pursuant to
               which certain First Mortgage Bonds of the Company (the "Class "A"
               Bonds") have been issued  (said  Mortgage and Deed of Trust as so
               amended  and  supplemented  is  herein  referred  to as the "1940
               Indenture");

                    (g) the  Company's  Indenture  of Mortgage and Deed of Trust
               dated as of  February  1,  1923,  to The First  National  Bank of
               Chicago,  as  trustee,  as amended  and  supplemented  ("ISU 1923
               Indenture");

                    (h)  Resolutions of the Executive  Committee of the Board of
               Directors  of the Company  dated  _________,  and the  Chairman's
               Certificate  dated  ___________,  pertaining to the authorization
               and sale of the  Bonds,  the terms  and  conditions  thereof  and
               related matters;

                    (i) Abstracts of Title and  Certificates  for title searches
               covering all pertinent  county records in the various counties in
               which  property of the Company is situated,  together  with title
               opinions of counsel  deemed by me to be competent  and  reputable
               and upon whom I  believe I am  justified  in  relying  as to such
               matters;

                    (j) copies of franchises of the Company and the  proceedings
               under which they were granted;

                    (k) the  Application  filed by the Company  with the Federal
               Energy  Regulatory   Commission  seeking,   among  other  things,
               authority  for and approval of the issuance and sale of Bonds and
               a copy of the Letter of Authority  issued by the Chief Accountant
               of such Commission,  dated __________,  authorizing and approving
               the issuance and sale of the Bonds;

                    (l) counterparts of the Underwriting  Agreement  executed by
               you and the Company; and

                    (m) other information,  documents, and material which I deem
               sufficient along with the foregoing to support this opinion.

                  In addition,  in connection with this opinion, I have reviewed

various  orders  and  certificates  of, and  members  of the legal  staff of IES
Industries Inc. had telephone  conversations with, public officials.  I have not
examined the Bonds, except a specimen thereof.


<PAGE>

                  Subject to the  foregoing  and to the further  exceptions  and
qualifications  set forth  below  and  having  regard  to all legal and  factual
considerations  which I deem relevant and based upon all such other  information
and documents furnished to or obtained by me as I believe necessary to enable me
to render this opinion,  including certificates of public officials, I am of the
opinion that:

                  1. The  Company  has been  duly  incorporated  and is  validly
existing and in good  standing as a  corporation  under the laws of the State of
Iowa,  with full power and authority  (corporate  and other) to own its property
and to conduct its business as presently being conducted all within the State of
Iowa.

                  2. The Bonds,  the  Mortgage,  the Class "A"  Bonds,  the 1940
Indenture  and the ISU 1923  Indenture  conform in all material  respects to the
descriptions thereof in the Prospectus.

                  3. The Underwriting  Agreement has been duly  authorized,  
executed and delivered on behalf of the Company.

                  4. The Class "A" Bonds  have been duly  authorized  and,  when
duly  executed,  authenticated,  issued  and  delivered  to  the  Trustee,  will
constitute valid and legally binding  obligations of the Company entitled to the
benefits and security  provided by the 1940 Indenture,  enforceable  against the
Company  in  accordance  with their  terms  except as the same may be limited by
bankruptcy,  insolvency,  fraudulent conveyance,  reorganization,  moratorium or
other similar laws  relating to or affecting  enforcement  of creditors'  rights
generally,  by  general  principles  of equity  (regardless  of  whether  or not
enforceability is considered in a proceeding in equity or at law).

                  5.  The  Bonds  have  been  duly  authorized  and,  when  duly
executed,  authenticated,  issued  and  delivered  to  and  paid  for  by you in
accordance with the terms of the Underwriting  Agreement,  will constitute valid
and legally  binding  obligations  of the Company  entitled to the  benefits and
security provided by the Mortgage, enforceable against the Company in accordance
with their terms  except as the same may be limited by  bankruptcy,  insolvency,
fraudulent conveyance, reorganization, moratorium or other similar laws relating
to  or  affecting  enforcement  of  creditors'  rights  generally,   by  general
principles of equity  (regardless of whether or not enforceability is considered
in a proceeding in equity or at law).

                  6.  The  Mortgage,  the  1940  Indenture,  and  the  ISU  1923
Indenture  have been duly and  validly  authorized  by all  necessary  corporate
action of the Company,  have been duly executed,  acknowledged  and delivered by
the Company and are valid and legally binding  instruments  enforceable  against
the  Company  in  accordance  with their  terms,  except as limited by laws with
respect to or affecting  the  remedies to enforce the  security  provided by the
Mortgage,  which  laws do not,  in my  opinion,  make  inadequate  the  remedies
necessary for the  realization of the benefits of such  security,  and except as
the  same may be  limited  by  bankruptcy,  insolvency,  fraudulent  conveyance,
reorganization,  moratorium  or other  similar  laws  relating  to or  affecting
enforcement  of creditors'  rights  generally,  by general  principles of equity
(regardless of whether enforceability is considered in a proceeding in equity or
at law) and by an implied covenant of good faith and fair dealing.

                  7. The execution and delivery of the  Underwriting  Agreement,
the consummation of the transactions therein contemplated and the fulfillment of
the terms  thereof do not and will not conflict  with, or result in a breach by,
the Company of any of the terms or provisions of, or constitute a default under,
the Articles of Incorporation or By-laws of the Company, the Mortgage,  the 1940
Indenture  or the ISU  1923  Indenture,  or to the  best of my  knowledge  after
reasonable investigation,  any other indenture, mortgage, deed of trust or other
agreement or instrument to which the Company is a party or by which it or any of
its  properties  are bound,  including the Agreement and Plan of Merger,  by and
among,  WPL Holdings,  Inc., IES Industries  Inc.,  Interstate  Power Company (a
Delaware  corporation),  WPLH  Acquisition  Co., and Interstate Power Company (a
Wisconsin corporation), dated as of November 10, 1995, as amended.

                  8.  The  Company  has  good  and  valid  title  to  all of the
principal  properties  subject to the lien of the Mortgage,  subject only to (a)
Permitted  Liens (as  defined in the  Mortgage),  (b) the prior lien of the 1940
Indenture on certain  properties  of the Company,  (c) the prior lien of the ISU
1923  Indenture  on  certain  other  properties  of the  Company  and (d)  minor
restrictions, exceptions and reservations in conveyance and defects which are of
a nature ordinarily found in property of a similar character and magnitude;  and
the Company  possesses  the power of eminent  domain with respect to its present
public utility operations.

                  9. The references in the Mortgage to the  descriptions  in the
1940 Indenture and the ISU 1923 Indenture of the properties  subject to the lien
of the 1940  Indenture and the ISU 1923 Indenture are adequate to constitute the
Mortgage a lien on such  properties,  subject  only to (a)  Permitted  Liens (as
defined in the  Mortgage),  (b) the prior lien of the 1940  Indenture on certain
properties  of the  Company,  (c) the prior  lien of the ISU 1923  Indenture  on
certain other properties of the Company and (d) minor  restrictions,  exceptions
and  reservations  in conveyance  and defects  which are of a nature  ordinarily
found in property of a similar character and magnitude; the Mortgage constitutes
a valid direct  mortgage lien upon all physical  properties in the State of Iowa
acquired  by the Company  after the date of the  Mortgage,  subject  only to (v)
Permitted  Liens (as  defined in the  Mortgage),  (w) the prior lien of the 1940
Indenture on certain  properties  of the Company,  (x) the prior lien of the ISU
1923  Indenture  on  certain  other   properties  of  the  Company,   (y)  minor
restrictions, exceptions and reservations in conveyance and defects which are of
a nature  ordinarily found in property of a similar  character and magnitude and
(z) liens,  charges or  encumbrances  existing or placed  thereon at the time of
acquisition.

                  10.  The  1940  Indenture  constitutes  a valid  direct  first
mortgage lien upon all properties  subject to the lien thereof,  subject only to
(a)  Permitted  Encumbrances  as defined  therein,  and (b) minor  restrictions,
exceptions  and  reservations  in  conveyance  and defects which are of a nature
ordinarily  found in property of a similar  character  and  magnitude;  the 1940
Indenture  constitutes  and will  constitute a valid direct first  mortgage lien
upon all physical properties and franchises in the State of Iowa acquired by the
Company after the date of the 1940  Indenture  until the Merger of Iowa Southern
Utilities  Company into the Company on December  31,  1993,  and on all property
thereafter  acquired by the Company other than property  which is appurtenant to
the property owned by Iowa Southern Utilities Company  immediately prior to such
merger,  subject only to (x) Permitted  Encumbrances (as defined  therein),  (y)
minor restrictions,  exceptions and reservations in conveyance and defects which
are of a nature ordinarily found in property of similar character and magnitude,
and (z) any liens,  charges or  encumbrances  existing or placed  thereon at the
time of acquisition.

                  11. The ISU 1923  Indenture  constitutes  a valid direct first
mortgage lien upon all properties  subject to the lien thereof,  subject only to
(a) Permitted Liens as defined therein,  and (b) minor restrictions,  exceptions
and  reservations  in conveyance  and defects  which are of a nature  ordinarily
found in property of a similar  character and magnitude;  the ISU 1923 Indenture
constitutes  and will  constitute a valid direct  first  mortgage  lien upon all
physical  properties  and  franchises  in the  State  of Iowa  acquired  by Iowa
Southern  Utilities  Company after the date of the ISU 1923 Indenture  until the
Merger of Iowa Southern Utilities Company into the Company on December 31, 1993,
and, on all property  thereafter acquired by the Company which is appurtenant to
the property owned by Iowa Southern Utilities Company  immediately prior to such
merger,  subject only to (x)  Permitted  Liens (as defined  therein),  (y) minor
restrictions, exceptions and reservations in conveyance and defects which are of
a nature  ordinarily found in property of similar  character and magnitude,  and
(z) any liens, charges or encumbrances existing or placed thereon at the time of
acquisition.

                  12.  The  Mortgage,  the  1940  Indenture,  and the  ISU  1923
Indenture have been duly filed and recorded in all  jurisdictions in which it is
necessary for the Mortgage, the 1940 Indenture, and the ISU 1923 Indenture to be
filed and  recorded  in order to  constitute  a lien of  record on the  property
subject  thereto;  appropriate  financing  statements  have  been  filed  in the
appropriate  offices in the State of Iowa;  and each such recording or filing is
fully  effective  to give  constructive  notice  of the  contents  of each  such
recorded or filed document to all  purchasers,  mortgagees  and secured  parties
(except for after-acquired property) covered thereby.

                  13. The Chief  Accountant  of the  Federal  Energy  Regulatory
Commission  ("FERC") has  authorized  the issuance and sale of the Bonds,  which
authorization  is, to the best of my knowledge,  still in full force and effect;
the issuance and sale of the Bonds to you pursuant to the Underwriting Agreement
are  in  conformity  with  the  terms  of  such  authorization;   and  no  other
authorization,  approval  or consent of any other  governmental  body is legally
required  for the issuance  and sale of the Bonds  pursuant to the  Underwriting
Agreement,  except such as have been obtained  under the Securities Act of 1933,
as  amended  ("Securities  Act"),  and  such  as may  be  required  under  state
securities or blue sky laws in connection with the purchase and  distribution of
the Bonds by you.

                  14.  Except as referred to in the  Registration  Statement and
Prospectus,  to the best of my knowledge,  there are no material or contemplated
legal proceedings to which the Company is or may be a party or of which property
of the  Company is or may be subject  which  depart  from the  ordinary  routine
litigation incident to the kinds of business conducted by the Company.

                  15. The documents  incorporated by reference in the Prospectus
(other than the financial  statements and financial and statistical  data, as to
which I express  no  opinion),  when they were  filed  with the  Securities  and
Exchange  Commission  (the  "Commission"),  complied as to form in all  material
respects with the  requirements  of the Securities  Exchange Act of 1934 and the
rules and  regulations  thereunder  of the  Commission;  and I have no reason to
believe that any of such documents, when they were so filed, contained an untrue
statement of a material  fact or omitted to state a material  fact  necessary in
order to make the statements  therein,  in the light of the circumstances  under
which they were made when such documents were so filed, not misleading.

                  16. To the best of my  knowledge,  there are no  contracts  or
other instruments or documents of a character required to be filed as an exhibit
to the  Registration  Statement or required to be incorporated by reference into
the Prospectus or required to be described in the Registration  Statement or the
Prospectus  which are not filed or  incorporated  by  reference  or described as
required.

                  17. The Company has the legal right to function and operate as
an  electric  and gas utility in the State of Iowa,  holds valid and  subsisting
franchises  authorizing  it to  carry  on the  utility  business  in which it is
engaged in all  incorporated  communities  having a population  of 1,000 or more
[(except in ______________, Iowa, where operations have not been impaired by the
expiration  of such  franchises)],  and has adequate  licenses and permits where
required by law to maintain electric and gas transmission and distribution lines
through  unincorporated  areas and over public lands not located in incorporated
communities and over private rights-of-way in the territory which it serves.

                  I am a member  of the bar of the State of Iowa and do not hold
myself  out as an expert on the laws of any other  State.  With  respect  to the
opinions set forth in Paragraphs 4, 5, and 6 above, I call your attention to the
fact that the  provisions  of the Atomic  Energy Act of 1954,  as  amended,  and
regulations   promulgated   thereunder   impose  certain   licensing  and  other
requirements upon persons (such as the Trustee,  as defined in the Mortgage,  or
other purchasers pursuant to the remedial  provisions of the Mortgage,  the 1940
Indenture,  or the ISU 1923  Indenture)  who  seek to  acquire,  possess  or use
nuclear production facilities.

                  The  opinion  set forth above is solely for the benefit of the
addressees  of this letter and may not be relied upon in any manner by any other
person without my prior written consent, except that Winthrop, Stimson, Putnam &
Roberts  may rely on this  opinion as to all  matters  of Iowa law in  rendering
their opinions required to be delivered under the Underwriting Agreement.


                                                             Very truly yours,

               [Letterhead of Winthrop, Stimson, Putnam & Roberts]



                                                                       [Date]



Re: IES Utilities Inc.
$__________ Collateral Trust Bonds ___% Series Due ____

Ladies and Gentlemen:

                  We have acted as Counsel for IES Utilities Inc. ("Company") in
connection  with the  issuance  and sale by the  Company to you  pursuant to the
Underwriting Agreement dated __________  ("Underwriting  Agreement") between the
Company and you, of  $_________ in principal  amount of  Collateral  Trust Bonds
___% Series Due ____ (the  "Bonds"),  issued  under the  Company's  Indenture of
Mortgage and Deed of Trust, dated as of September 1, 1993, to The First National
Bank of Chicago, as Trustee (the "Trustee"),  as heretofore  supplemented and as
further  supplemented  by  the  _____  Supplemental   Indenture,   dated  as  of
__________.  Said Indenture of Mortgage and Deed of Trust as so  supplemented is
herein referred to as the "Mortgage".

                  We are members of the New York Bar and,  for  purposes of this
opinion,  do not hold  ourselves out as experts on the laws of any  jurisdiction
other than the State of New York and the United States of America. We have, with
your consent,  relied upon the opinion of even date herewith addressed to you by
__________,  Counsel for IES Industries  Inc., as to the matters covered in such
opinion  relating to Iowa law. We have reviewed said opinion and believe that it
is satisfactory and that you and we are justified in relying thereon.

                  We also examined such other documents and questions of law and
satisfied  ourselves  as to such other  matters as we have deemed  necessary  in
order to  enable  us to  express  this  opinion.  We have not  examined  and are
expressing no opinion or belief as to matters  relating to the  incorporation of
the Company,  titles to property of the Company,  franchises of the Company,  or
the descriptions of properties in, the nature and the extent of the lien of, the
absence of liens and  encumbrances  prior to the lien of, or the recordation of,
the  Mortgage,  IELP 1940  Mortgage and ISU 1923  Mortgage (the terms "IELP 1940
Mortgage" and "ISU 1923  Mortgage" as used herein shall have the same meaning as
those terms in the  Mortgage).  We also have not  examined  the Bonds,  except a
specimen thereof.  As to various questions of fact material to this opinion,  we
have  relied   upon   representations   and   certificates   of   officers   and
representatives of the Company and statements in the Registration Statement (the
terms  "Registration  Statement" and "Prospectus," as used herein, have the same
meanings as those words in the  Underwriting  Agreement).  We have also examined
originals,  or  copies  of  originals  certified  to our  satisfaction,  of such
agreements,  documents, certificates and other instruments as we have considered
relevant and necessary as a basis for such opinion. In such examination, we have
assumed the  genuineness of all  signatures,  the  authenticity of all documents
submitted  to us as  originals,  and  the  conformity  to the  originals  of the
documents submitted to us as certified or photostatic copies.

                  Subject to the  foregoing  and to the further  exceptions  and
qualifications set forth below, we are of the opinion that:

                  1. The  Mortgage has been duly and validly  authorized  by all
necessary corporate action of the Company, has been duly executed,  acknowledged
and  delivered  by the  Company and is a valid and  legally  binding  instrument
enforceable  against the Company in accordance with its terms, except as limited
by laws with  respect to or  affecting  the  remedies  to enforce  the  security
provided by the Mortgage, and by bankruptcy,  insolvency, fraudulent conveyance,
reorganization,  moratorium  or other  similar  laws  relating  to or  affecting
enforcement  of creditors'  rights  generally,  by general  principles of equity
(regardless of whether enforceability is considered in a proceeding in equity or
at law) and by an  implied  covenant  of good  faith and fair  dealing;  and the
Indenture  has been duly  qualified  under the Trust  Indenture  Act of 1939, as
amended (the "Trust Indenture Act").

                  2.  The  Bonds  have  been  duly  authorized  and,  when  duly
executed,  authenticated,  issued  and  delivered  to  and  paid  for  by you in
accordance with the terms of the Underwriting  Agreement,  will constitute valid
and legally  binding  obligations  of the Company  entitled to the  benefits and
security provided by the Indenture enforceable against the Company in accordance
with their terms  except as the same may be limited by  bankruptcy,  insolvency,
fraudulent conveyance, reorganization, moratorium or other similar laws relating
to  or  affecting  enforcement  of  creditors'  rights  generally,   by  general
principles of equity  (regardless of whether  enforceability  is considered in a
proceeding  in equity or at law) and by an  implied  covenant  of good faith and
fair dealing.

                  3. The summaries of the terms of the Mortgage,  the Bonds, the
Class "A" Bonds (as defined in the Mortgage), the IELP 1940 Mortgage and the ISU
1923 Mortgage contained in the Registration  Statement and the Prospectus fairly
describe  in  all  material  respects  the  provisions  thereof  required  to be
described by the registration statement form.

                  4.  The  Underwriting  Agreement  has been duly  authorized,  
executed and delivered by the Company.

                  5. The execution and delivery of the  Underwriting  Agreement,
the consummation of the transactions therein contemplated and the fulfillment of
the terms  thereof do not and will not conflict  with,  or result in a breach by
the  Company  of, any of the terms or  provisions  of, or  constitute  a default
under, the Articles of  Incorporation  or By-laws of the Company,  the Mortgage,
the IELP 1940 Mortgage, the ISU 1923 Mortgage, or, to the best of our knowledge,
any other indenture, mortgage, deed of trust or other agreement or instrument to
which the Company is a party or by which it or any of its properties are bound.

                  6. The  Chief  Accountant  of the  Federal  Energy  Regulatory
Commission  has   authorized   the  issuance  and  sale  of  the  Bonds,   which
authorization is, to the best of our knowledge,  still in full force and effect;
the issuance and sale of the Bonds to you pursuant to the Underwriting Agreement
are  in  conformity  with  the  terms  of  such  authorization;   and  no  other
authorization, approval or consent of any other federal commission or regulatory
authority is legally required for the issuance and sale of the Bonds pursuant to
the  Underwriting  Agreement,  except  such  as have  been  obtained  under  the
Securities  Act of 1933, as amended  ("Securities  Act") or the Trust  Indenture
Act.

                  7. To the best of our knowledge,  the  Registration  Statement
is, at the date hereof,  effective  under the  Securities  Act and no stop order
suspending the  effectiveness of the Registration  Statement has been issued and
no proceedings for a stop order with respect thereto have been instituted or are
pending or threatened under the Securities Act; the Registration  Statement,  at
the time of its effectiveness,  and the Prospectus, at the time first filed with
the Securities and Exchange Commission ("Commission") pursuant to Rule 424 under
the  Securities  Act,  complied  as to form in all  material  respects  with the
requirements  of the  Securities  Act  and  the  Trust  Indenture  Act,  and the
applicable  rules and regulations of the Commission  thereunder  (except that we
express  no  opinion  as to the  financial  statements  or  other  financial  or
statistical data included or incorporated by reference therein or as to the Form
T-1 filed as an exhibit to the Registration Statement).

                  8. The Company and IES  Industries Inc. are  currently  exempt
from  regulation  under the  Public  Utility  Holding  Company  Act of 1935,  as
amended, except under Section 9(a)(2) thereof.

                  9. To the best of our  knowledge,  there are no  contracts  or
other instruments or documents of a character required to be filed as an exhibit
to the  Registration  Statement or required to be incorporated by reference into
the Prospectus or required to be described in the Registration  Statement or the
Prospectus  which are not filed or  incorporated  by  reference  or described as
required.

                  In passing upon the forms of the  Registration  Statement  and
the Prospectus,  we necessarily  assume the correctness and  completeness of the
statements made by the Company and the  information  included or incorporated by
reference  in  the  Registration  Statement  and  the  Prospectus  and  take  no
responsibility  therefor,  except insofar as such statements relate to us and as
set forth in  paragraph  3 above.  In  connection  with the  preparation  of the
Registration Statement and the Prospectus,  we have had discussions with certain
of the  Company's  officers  and  representatives,  with other  counsel  for the
Company,  with your  counsel  and with  Arthur  Andersen  LLP,  the  independent
certified public  accountants who examined  certain of the financial  statements
included  or  incorporated  by  reference  in the  Registration  Statement.  Our
examination of the Registration Statement and the Prospectus and our discussions
did not disclose to us any information  that gives us reason to believe that the
Registration  Statement,  at the time it became  effective,  contained an untrue
statement of a material  fact or omitted to state a material fact required to be
stated therein or necessary to make the statements  therein not  misleading,  or
that the  Prospectus,  at the time first filed with the  Commission  pursuant to
Rule 424 under the Securities Act and at the date hereof,  contained or contains
an untrue  statement of a material  fact or omitted or omits to state a material
fact  necessary  in order to make the  statements  therein,  in the light of the
circumstances under which they were made, not misleading.  We do not express any
opinion  or  belief  as to  the  financial  statements  or  other  financial  or
statistical  data  included or  incorporated  by reference  in the  Registration
Statement or the  Prospectus or as to the  statements  contained in the Form T-1
filed as an exhibit to the Registration Statement.

                  With respect to the  opinions set forth in  Paragraphs 1 and 2
above,  we call your  attention  to the fact that the  provisions  of the Atomic
Energy Act of 1954, as amended,  and regulations  promulgated  thereunder impose
certain licensing and other  requirements upon persons (such as the Trustee,  as
defined in the Mortgage, or other purchasers pursuant to the remedial provisions
of the Mortgage,  the IELP 1940 Mortgage, and the ISU 1923 Mortgage) who seek to
acquire, possess or use nuclear production facilities.

                  As  used in  this  opinion,  the  phrase  "to the  best of our
knowledge" is intended to mean the actual knowledge or information  known by the
lawyers  in our firm who have  been  principally  involved  in the  transactions
contemplated by the Underwriting Agreement.

                  The  opinion  set forth  above is solely  for your  benefit in
connection with the  Underwriting  Agreement and the  transactions  contemplated
thereunder  and may not be quoted or furnished  to, or relied upon in any manner
by, any other person or utilized for any other purpose without our prior written
consent.

                                            Very truly yours,


                                            WINTHROP, STIMSON, PUTNAM & ROBERTS

                      [Letterhead of Dorsey & Whitney LLP]


                                                              [Date]


Re:  IES Utilities Inc.
$__________ Collateral Trust Bonds ___% Series Due ____


Ladies and Gentlemen:

                  We have acted as your counsel in connection  with the issuance
and  sale  by  IES  Utilities,  Inc.  (the  "Company")  to you  pursuant  to the
Underwriting Agreement dated __________  ("Underwriting  Agreement") between the
Company and you, of  $__________ in principal  amount of Collateral  Trust Bonds
___% Series (the  "Bonds"),  issued under the Company's  Indenture,  dated as of
September  1, 1993,  to The First  National  Bank of  Chicago,  as Trustee  (the
"Trustee"),  as supplemented by the _____  Supplemental  Indenture,  dated as of
__________.  Said Indenture of Mortgage and Deed of Trust as so  supplemented is
herein referred to as the "Mortgage").  This opinion is being delivered pursuant
to Section 8(d) of the Underwriting Agreement.

                  We have examined such documents and reviewed such questions of
law as we have  considered  necessary and  appropriate  for the purposes of this
opinion.

                  In  rendering  our  opinions   below,   we  have  assumed  the
authenticity of all documents  submitted to us as originals,  the genuineness of
all  signatures  and the  conformity  to authentic  originals  of all  documents
submitted to us as copies or specimens.  We have also assumed the legal capacity
for all purposes relevant hereto of all natural persons and, with respect to all
parties to agreements  or  instruments  relevant  hereto other than the Company,
that such parties had the requisite power and authority  (corporate or other) to
execute,  deliver  and  perform  such  agreements  or  instruments,   that  such
agreements or  instruments  have been duly  authorized  by all requisite  action
(corporate  or other),  executed  and  delivered  by such  parties and that such
agreements or instruments are the valid, binding and enforceable  obligations of
such parties.  As to questions of fact material to our opinions,  we have relied
on certificates of officers of the Company and of public officials.

                  Certain of our opinions  expressed below as to factual matters
are qualified as being limited "to the best of our  knowledge" or by other words
to the same or similar effect.  Such words, as used herein, mean the information
known  to  ___________,  ___________  and  __________,  the  attorneys  who have
represented  you  in  connection  with  the  transactions  contemplated  by  the
Underwriting  Agreement.  In rendering such opinions,  we have not conducted any
independent  investigation  or consulted  with other  attorneys in our firm with
respect to the matters covered thereby.

                  On the basis of such  examination,  we advise you that, in our
opinion:

                  1. The Company is a validly organized and existing corporation
in good standing under the laws of the State of Iowa.

                  2. The  Underwriting  Agreement  has been duly  authorized,  
executed and delivered by the Company.

                  3. The  Mortgage has been duly and validly  authorized  by all
requisite   corporate  action,   executed  and  delivered  by  the  Company  and
constitutes a valid and legally binding  obligation of the Company,  enforceable
against the Company in accordance with its terms.

                  4.  The Mortgage has been duly qualified  under the Trust  
Indenture Act of 1939, as amended ("Trust Indenture Act").

                  5. The  Bonds  have  been  duly  authorized  by all  requisite
corporate action and, when duly executed, authenticated, issued and delivered to
and paid for by you in accordance with the terms of the Underwriting  Agreement,
will constitute valid and legally binding obligations of the Company entitled to
the benefits and security provided by the Mortgage.

                  6. The  Chief  Accountant  of the  Federal  Energy  Regulatory
Commission  has   authorized   the  issuance  and  sale  of  the  Bonds,   which
authorization is, to the best of our knowledge,  still in full force and effect;
the issuance and sale of the Bonds to you pursuant to the Underwriting Agreement
is  in  conformity  with  the  terms  of  such   authorization;   and  no  other
authorization, approval or consent of any other federal commission or regulatory
authority is legally required for the issuance and sale of the Bonds pursuant to
the  Underwriting  Agreement,  except  such  as have  been  obtained  under  the
Securities Act of 1933, as amended  ("Securities  Act"),  or the Trust Indenture
Act.

                  7. The  Company's  registration  statements  on Form S-3 (File
Nos.  33-62259  and  333-_____)  relating  to  the  Bonds   (collectively,   the
"Registration  Statement")  have become effective under the Securities Act, and,
to the best of our knowledge,  no stop order suspending the effectiveness of the
Registration  Statement has been issued and no proceedings for a stop order with
respect  thereto have been  instituted  or are pending or  threatened  under the
Securities Act.

                  8. The Company is a subsidiary of IES Industries Inc., an Iowa
corporation,  and both are  exempt  from  regulation  under the  Public  Utility
Holding Company Act of 1935, as amended, except under Section 9(a)(2) thereof.

The opinions  set forth above are subject to the  following  qualifications  and
exceptions:

                  (a) Our opinions  are subject to the effect of any  applicable
bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer or other
similar law of general application affecting creditors' rights.

                  (b)  Our  opinions  are  subject  to  the  effect  of  general
principles of equity,  including (without  limitation)  concepts of materiality,
reasonableness,  good faith and fair dealing, estoppel, election of remedies and
other similar doctrines  affecting the  enforceability  of agreements  generally
(regardless of whether considered in a proceeding in equity or at law).

                  (c) We express no opinion concerning any person's rights in or
title to any real or personal property. We express no opinion with regard to the
filing or recording of any agreement or  instrument.  We express no opinion with
respect  to the  validity,  perfection  or  priority  of any  lien  or  security
interest.

                  (d) The  rights  of  debtors,  guarantors  and  other  secured
parties  to  receive  notices  under  Sections  9-504 and  9-505 of the  Uniform
Commercial  Code  ("UCC")  may not be waived  prior to  default,  the failure to
comply  with  such  notice  requirements  may bar or limit the  recovery  of any
deficiency remaining after the retention or sale of repossessed collateral,  and
a secured party may be required to obtain, after appropriate notice and hearing,
a judgment or decree of a court of competent jurisdiction permitting the secured
party to  enforce  its  rights  to take  possession  and  dispose  of any of its
collateral.

                  (e) The  rights  of  debtors,  guarantors  and  other  secured
parties to redeem  collateral  under  Section 9-506 of the UCC may not be waived
prior to default.

                  (f) The duties to exercise  reasonable care in the custody and
preservation of collateral in a secured party's  possession and to deal with and
dispose of collateral in a commercially reasonable manner as required by the UCC
or other  applicable law may not be disclaimed by agreement,  waived or released
prior to default.

                  (g)  Notwithstanding  certain  language of the  Mortgage,  the
Trustee  may be limited to recovery of only  reasonable  expenses or  attorneys'
fees and legal expenses with respect to the  enforcement of the Mortgage and the
liens or security interests created under the Mortgage.

                  (h)  We express  no  opinion  as to the  enforcement  of  
indemnification provisions in the Mortgage.

                  (i) Certain  rights,  remedies  and waivers  contained  in the
Mortgage may be limited or rendered  ineffective  by applicable  laws  governing
such  provisions,  but such laws do not,  in our  opinion,  render the  Mortgage
invalid as a whole,  or invalidate  the  obligations  created  thereunder or the
liens or security  interests created thereby,  and the Mortgage does contain the
customary  remedial  provisions  which are normally  used to allow the practical
realization of the rights and benefits afforded thereby.

                  (j) The  provisions  of the  Atomic  Energy  Act of  1954,  as
amended, and regulations  promulgated  thereunder,  impose certain licensing and
other  requirements  upon  persons  (such as the  Trustee  or  other  purchasers
pursuant  to the  remedial  provisions  of the  Mortgage)  who seek to  acquire,
possess or use nuclear production facilities.

                  Our  opinions  expressed  above are limited to the laws of the
States  of Iowa  and New York  and the  federal  laws of the  United  States  of
America.

                  The foregoing  opinions are being  furnished to you solely for
your benefit and may not be relied upon by, nor may copies be delivered  to, any
other person without pour prior written consent.


                                                     Very truly yours,

                                                     DORSEY & WHITNEY LLP

                      [Letterhead of Dorsey & Whitney LLP]


                                                              [Date]


Re:  IES Utilities Inc.
$__________ Collateral Trust Bonds ___% Series Due ____


Ladies and Gentlemen:

                  This letter relates to the  registration  under the Securities
Act of 1933, as amended (the "Act"),  and offering of  $__________  in aggregate
principal amount of Collateral  Trust Bonds,  ___% Series Due ____ (the "Bonds")
of IES Utilities Inc., an Iowa  corporation  (the  "Company").  The registration
statements  of the  Company  on Form S-3  (File  Nos.  33-62259  and  333-_____)
(collectively,  the  "Registration  Statement")  was  filed in  accordance  with
procedures  of  the  Securities  and  Exchange   Commission  (the  "Commission")
permitting a delayed or continuous  offering of securities pursuant thereto and,
if  appropriate,  a  post-effective  amendment  or  prospectus  supplement  that
provides  information  relating to the terms of the securities and the manner of
their  distribution.  The  Bonds  have  been  offered  by the  Prospectus  dated
__________ (the  "Prospectus"),  as  supplemented  by the Prospectus  Supplement
dated  __________ (the  "Prospectus  Supplement"),  which updates or supplements
certain  information  contained  in  the  Prospectus.   The  Prospectus,  as  so
supplemented,  does  not  necessarily  contain  a  current  description  of  the
Company's  business and affairs since,  pursuant to form S-3, it incorporates by
reference certain documents filed with the Commission which contain  information
as of various dates.

                  In accordance with our understanding  with you as to the scope
of our services under the circumstances applicable to the offering of the Bonds,
we reviewed  the  Registration  Statement,  the  Prospectus  and the  Prospectus
Supplement,  participated in the discussions with your representatives and those
of the Company,  its counsel and its independent  public accountants and advised
you as to the  requirements of the Act and the applicable  rules and regulations
thereunder.  Between  the  date of the  Prospectus  Supplement  and the  date of
delivery  of this  letter,  we  participated  in further  discussions  with your
representatives and those of the Company, its counsel and its independent public
accountants regarding the contents of certain portions of the Prospectus and the
Prospectus  Supplement and certain related matters, and reviewed certificates of
certain officers of the Company,  opinions  addressed to you from counsel to the
Company and letters addressed to you from independent  public accountants of the
Company.

                  On the basis of the information that was reviewed by us in the
course of the performance of the services  referred to above, in our opinion (i)
the  Registration  Statement,  as of its effective date, and the Prospectus,  as
supplemented  by the  Prospectus  Supplement  as of the  date of the  Prospectus
Supplement,  complied as to form in all material  respects with the requirements
of the Act and the Trust Indenture Act of 1939, as amended,  and the respective,
applicable  rules and regulations  thereunder (ii) the summaries of the terms of
the Mortgage,  the Bonds,  the Class "A" Bonds,  the 1940  Indenture and the ISU
1923  Indenture (as such terms are defined in the  Prospectus)  contained in the
Registration  Statement,  the Prospectus and the  Prospectus  Supplement  fairly
describe  in  all  material  respects  the  provisions  thereof  required  to be
described in the registration statement form. Further,  nothing that came to our
attention  in the  course  of such  review  has  caused us to  believe  that the
Registration  Statement,  on such effective date, contained any untrue statement
of a material  fact or omitted to state any material  fact required to be stated
therein or necessary to make the statements therein not misleading,  or that the
Prospectus,  as supplemented by the Prospectus Supplement, as of the date of the
Prospectus  Supplement  and as of the date and time of delivery of this  letter,
contained or contains an untrue statement of a material fact or omitted or omits
to state a material fact necessary in order to make the statements  therein,  in
light of the circumstances under which they were made, not misleading.

                  The limitations  inherent in the  independent  verification of
factual matters and the character of determinations involved in the registration
process  are such,  however,  that we do not assume any  responsibility  for the
accuracy,   completeness  or  fairness  of  the  statements   contained  in  the
Registration Statement, the Prospectus or the Prospectus Supplement. Also, we do
not  express  any  opinion  or belief as to the  financial  statements  or other
financial data contained in the  Registration  Statement,  the Prospectus or the
Prospectus   Supplement,   or  as  to  the  statement  of  the  eligibility  and
qualification of the Trustee under the Indenture under which the Bonds are being
issued.

                  This  letter is  furnished  by us as counsel to you solely for
your benefit and may not be relied upon by, nor may copies be delivered  to, any
other person without our prior written consent.

                                                     Very truly yours,

                                                     DORSEY & WHITNEY LLP

                                                                       EXHIBIT D


                  Pursuant to  subsection  (e) of Section 8 of the  Underwriting
Agreement,  Arthur Andersen LLP shall furnish a letter to the  Representative to
the effect that:

         (1) They are independent  certified public  accountants with respect to
the  Company  within  the  meaning  of the  Securities  Act and  the  applicable
published rules and regulations thereunder;

         (2) In their opinion, the financial statements and schedules audited by
them and included or  incorporated  by reference in the Prospectus  comply as to
form in all material respects with the applicable accounting requirements of the
Securities  Act  and  the  Exchange  Act and the  related  published  rules  and
regulations thereunder;

         (3) On the basis of performing the procedures specified by the American
Institute  of Certified  Public  Accountants  for a review of interim  financial
information as described in SAS No. 71, Interim  Financial  Information,  on the
latest  available  unaudited  financial  statements  included or incorporated by
reference  in the  Registration  Statement,  a reading of the  latest  available
interim  unaudited  financial  statements  of the  Company,  the  minutes of the
meetings of the Board of  Directors,  the  Executive  Committee  thereof and the
stockholders  of the Company,  respectively,  since the close of the most recent
audited  fiscal year to a specified  date not more than five business days prior
to the  Closing  Date,  and  inquiries  of  officials  of the  Company  who have
responsibility for the respective company's financial and accounting matters (it
being  understood that the foregoing  procedures do not constitute an audit made
in accordance with generally accepted auditing standards and that they would not
necessarily  reveal matters of significance with respect to the comments made in
such letter, and, accordingly,  that Arthur Andersen LLP makes no representation
as  to  the  sufficiency  of  such  procedures  for  the  several  Underwriters'
purposes), nothing has come to their attention which caused them to believe that

                  (a)   any   unaudited   financial   statements   included   or
incorporated  by  reference  in the  Prospectus  do not comply as to form in all
material respects with the applicable accounting  requirements of the Securities
Act and  the  Exchange  Act and the  related  published  rules  and  regulations
thereunder;

                  (b)  the  audited  and  any   unaudited   selected   financial
information  and  supplemental  financial  information and ratios of earnings to
fixed charges  included or  incorporated  by reference in the  Prospectus do not
comply  as to form in all  material  respects  with  the  applicable  disclosure
requirements of Regulation S-K promulgated under the Securities Act;

                  (c)  any  material  modifications  should  be  made  to  said 
unaudited  financial  statements  for them to be in  conformity  with  generally
accepted accounting principles;

                  (d) for the period from  ___________ to the date of the latest
available unaudited financial statements of the Company,  there was any decrease
in  operating  revenues,  operating  income or net income as  compared  with the
corresponding  period  in  the  preceding  year,  except  in all  instances  for
decreases which the Prospectus discloses have occurred or may occur or except as
set forth in such letter; and

                  (e) at a specified date not more than ______ days prior to the
Closing Date there was any change in the capital stock or long-term  debt of the
Company,  in each case as compared with amounts shown in the most recent balance
sheet  incorporated by reference in the Prospectus,  except in all instances for
changes or decreases which the Prospectus  discloses have occurred or may occur,
for  declarations  of  dividends,  for the  repayment or redemption of long-term
debt,  for the  amortization  of premium or discount on long-term  debt, for the
redemption  or purchase of preferred  stock for sinking fund  purposes,  for any
increases in long-term debt in respect of previously  issued  pollution  control
revenue  bonds,  or for  changes  or  decreases  as set  forth  in such  letter,
identifying the same and specifying the amount thereof.

         (4) In addition to the audit  referred to in their reports  included or
incorporated  by reference in the Prospectus and the inspection of minute books,
inquiries and other limited  procedures  referred to in paragraph 3 above,  they
have carried out certain  specified  procedures,  not  constituting  an audit in
accordance with generally accepted auditing  standards,  with respect to certain
amounts,  percentages  and  financial  information  including  certain pro forma
information  specified by the Representative  which are derived from the general
accounting  records of the Company  which  appear in the  Prospectus  (excluding
documents  incorporated  by  reference),  or in Part II of, or in  exhibits  and
schedules to, the Registration  Statement  specified by the Representative or in
documents   incorporated  by  reference  in  the  Prospectus  specified  by  the
Representative  and agreed to by the Company,  and have compared certain of such
amounts,  percentages and financial  information with the accounting  records of
the Company and have found them to be in agreement.

                             UNDERWRITING AGREEMENT


                   For the Purchase of Subordinated Debentures
                              of IES Utilities Inc.



IES UTILITIES INC.
c/o Winthrop, Stimson, Putnam & Roberts
One Battery Park Plaza
New York, New York 10004-1490


                  SECTION   1.   Purchase   and  Sale.   On  the  basis  of  the
representations  and warranties,  and subject to the terms and  conditions,  set
forth in this agreement  ("Underwriting  Agreement"),  each Underwriter (defined
below) shall  purchase from IES Utilities  Inc.  ("Company"),  severally and not
jointly, and the Company shall sell to each of the Underwriters (defined below),
the principal amount of the Company's unsecured junior  subordinated  debentures
("Subordinated  Debentures")  set forth opposite the name of such Underwriter in
Schedule II hereto at the price  specified  in Schedule I hereto,  plus  accrued
interest,  if any, at the rate  specified  in Schedule I hereto.  The  aggregate
principal  amount  of such  Subordinated  Debentures  being  sold  hereunder  is
hereinafter referred to as the "Debentures."

                  SECTION  2.   Underwriters   and   Representative.   The  term
"Underwriters,"  as used  herein,  shall be deemed to mean the several  persons,
firms,  or corporations  named in Schedule II hereto  (including any substituted
Underwriters under the provisions of Section 6), and the term  "Representative,"
as used herein, shall be deemed to mean the representative or representatives of
such  Underwriters  by whom or on whose  behalf this  Underwriting  Agreement is
signed.  If there  shall  be one  person,  firm,  or  corporation  named in said
Schedule  II, the term  "Underwriters"  and the term  "Representative,"  as used
herein,  shall mean that person,  firm, or  corporation.  All obligations of the
Underwriters are several and not joint. The use of the term "Underwriter" herein
shall not be deemed to establish or admit that a purchaser of the  Debentures is
an "Underwriter" of the Debentures as such term is defined in and used under the
Securities Act of 1933, as amended ("Securities Act").

                  SECTION 3. Description of the Debentures. The Debentures shall
be in the aggregate  principal  amount and shall mature on the date specified in
Schedule I hereto,  and shall be issued under and secured by the Indenture  (For
Unsecured   Subordinated   Debt  Securities)   dated  as  of  December  1,  1995
("Indenture"),  of the Company to The First  National Bank of Chicago as Trustee
("Trustee").  The Debentures shall bear interest at the rate per annum specified
in Schedule I hereto.  The Debentures and the Indenture are more fully described
in the Prospectus hereinafter referred to. 

                  SECTION 4.  Representations  and  Warranties  of the  Company.
The Company represents and warrants that:

          (a)  It  has  filed  with  the  Securities  and  Exchange   Commission
     ("Commission")   two  registration   statements  (File  Nos.  33-62259  and
     333-_____)   (collectively,   the   "Registration   Statement")   for   the
     registration of up to an aggregate of $135,000,000  principal amount of the
     Company's debt securities under the Securities Act. Registration statements
     (File Nos.  33-62259 and 333-_____)  have become  effective.  No stop order
     suspending the effectiveness of the Registration Statement has been issued,
     and no  proceedings  for that purpose have been  initiated or threatened by
     the Commission. The prospectus (including the supplement thereto) forming a
     part of the  Registration  Statement,  at that time  pursuant to Item 12 of
     Form S-3,  is  hereinafter  referred to as the "Basic  Prospectus."  In the
     event  that the Basic  Prospectus  shall  have been  amended,  revised,  or
     supplemented  (but excluding any amendments,  revisions,  or supplements to
     the Basic  Prospectus  relating  solely to the offering of debt  securities
     other  than the  Debentures)  prior to the  time of  effectiveness  of this
     Underwriting  Agreement,  and with  respect to any  documents  filed by the
     Company pursuant to Section 13, 14, or 15(d) of the Securities Exchange Act
     of 1934,  as  amended  ("Exchange  Act"),  after the time the  Registration
     Statement initially became effective and up to the time of effectiveness of
     this Underwriting  Agreement (but excluding documents  incorporated therein
     by reference  relating solely to the offering of debt securities other than
     the Debentures), which documents are deemed to be incorporated by reference
     in the Basic Prospectus,  the term "Basic  Prospectus" as used herein shall
     also mean such  prospectus as so amended,  revised,  or  supplemented.  The
     Registration  Statement as it initially became effective and as it may have
     been amended by any amendment thereto  incorporated in the Basic Prospectus
     (including for these purposes as an amendment any document  incorporated by
     reference in the Basic  Prospectus) and the Basic Prospectus as it shall be
     supplemented to reflect the terms of offering and sale of the Debentures by
     a  prospectus  supplement  ("Prospectus  Supplement")  to be filed with the
     Commission  pursuant to Rule 424 under the Securities Act ("Rule 424"), are
     hereinafter   referred  to  as  the   "Registration   Statement"   and  the
     "Prospectus," respectively;

          (b) After the time of  effectiveness of this  Underwriting  Agreement,
     the Company will not file (i) any amendment to the  Registration  Statement
     (except any amendment  relating  solely to the offering of debt  securities
     other than the Debentures) or supplement to the Prospectus or (ii) prior to
     the time that the Prospectus is filed with the Commission  pursuant to Rule
     424,  any document  which is to be  incorporated  by  reference  in, or any
     supplement (including the Prospectus  Supplement) to, the Basic Prospectus,
     in either  case  without  prior  notice to each of the  Representative  and
     Dorsey  &  Whitney  LLP  ("Counsel  for  the  Underwriters"),  or any  such
     amendment,  supplement,  or document to which said Counsel shall reasonably
     object on legal  grounds in  writing.  For  purposes  of this  Underwriting
     Agreement,  any document filed with the Commission after the  effectiveness
     of  this  Underwriting  Agreement  and  incorporated  by  reference  in the
     Prospectus  (except documents  incorporated by reference relating solely to
     the offering of debt securities other than the Debentures) pursuant to Item
     12 of Form S-3 shall be deemed a supplement to the Prospectus;

          (c) The  Registration  Statement,  at the  time of its  effectiveness,
     fully  complied,  the Indenture,  at the time of its execution,  will fully
     comply, and the Prospectus, when filed with the Commission pursuant to Rule
     424  and at the  Closing  Date  (hereinafter  defined),  as it may  then be
     supplemented or amended,  will fully comply,  in all material respects with
     the applicable provisions of the Securities Act, the Trust Indenture Act of
     1939, as amended ("Trust  Indenture Act"), and the rules and regulations of
     the Commission thereunder or pursuant to said rules and regulations will be
     deemed to comply therewith;  the documents incorporated by reference in the
     Prospectus  pursuant  to Item 12 of Form S-3,  on the date first filed with
     the Commission pursuant to the Exchange Act, fully complied and on the date
     the Prospectus is filed with the Commission pursuant to Rule 424 and at the
     Closing Date  (hereinafter  defined)  will comply in all material  respects
     with the  applicable  provisions  of the  Exchange  Act and the  rules  and
     regulations  of the  Commission  thereunder  or  pursuant to said rules and
     regulations  were or will be  deemed to  comply  therewith;  on the date of
     effectiveness  of  the  Registration   Statement  and  any   post-effective
     amendment thereto (but excluding in each case any post-effective  amendment
     relating  solely  to  the  offering  of  debt  securities  other  than  the
     Debentures)  or, if later than such dates,  on the date that the  Company's
     most recent annual report on Form 10-K was filed with the Commission  under
     the  Exchange  Act,  the  Registration  Statement,  as  amended by any such
     post-effective  amendment, did not or will not, as the case may be, contain
     an untrue  statement  of a material  fact or omit to state a material  fact
     required to be stated therein or necessary to make the  statements  therein
     not misleading; the Prospectus, at the date it is filed with the Commission
     pursuant to Rule 424 and at the Closing Date (hereinafter  defined),  as it
     may be amended or  supplemented,  will not include an untrue statement of a
     material fact or omit to state a material  fact  necessary in order to make
     the statements  therein, in the light of the circumstances under which they
     are  made,  not  misleading;  and on  said  dates  and at such  times,  the
     documents then incorporated by reference in the Prospectus pursuant to Item
     12 of Form S-3, when read together with the  Prospectus,  or the Prospectus
     as it may then be  amended  or  supplemented,  will not  contain  an untrue
     statement of a material  fact or omit to state a material  fact required to
     be stated therein or necessary to make the statements therein, in the light
     of the circumstances under which they were made, not misleading;  provided,
     however, that the foregoing representations and warranties in this --------
     -------  subsection  (c) shall not apply to statements or omissions made in
     reliance upon and in conformity with written  information  furnished to the
     Company by or through the  Representative  on behalf of any Underwriter for
     use in connection with the preparation of the Registration Statement or the
     Prospectus, as they may be amended or supplemented, or to any statements in
     or omissions from the statement of eligibility, as it may be amended, under
     the Trust Indenture Act of the Trustee under the Indenture;

          (d) The  Federal  Energy  Regulatory  Commission  has  authorized  the
     issuance and sale of the Debentures;  such  authorization  is in full force
     and  effect;  the  issuance  and sale of the  Debentures  pursuant  to this
     Underwriting  Agreement  will not violate the terms of such  authorization;
     and no other  authorization,  approval or consent of any other governmental
     body or regulatory  authority is legally required for the issuance and sale
     of the Debentures pursuant to this Underwriting  Agreement,  except such as
     have been obtained under the Securities Act and the Trust Indenture Act and
     such as may be required  under the state  securities  or "blue sky" laws in
     connection  with the purchase and  distribution  of the  Debentures  by the
     Underwriters;

          (e) The  Company  is a  corporation  duly  incorporated,  and  validly
     existing,  and in good standing under the laws of the State of Iowa and has
     full power and authority  (corporate  and other) under such laws to own its
     properties  and to conduct its business as  described  in the  Registration
     Statement  and  the  Prospectus;  and the  Company  does  not own or  lease
     substantial  properties or conduct its business in any state other than the
     State of Iowa;

          (f) The  Debentures  have been duly  authorized,  and, when issued and
     delivered  pursuant  to this  Agreement,  will  have  been  duly  executed,
     authenticated,  issued and delivered and will constitute  valid and legally
     binding obligations of the Company entitled to the benefits provided by and
     secured by the Indenture; the Indenture has been duly authorized,  executed
     and delivered by the Company and the Trustee,  and  constitutes a valid and
     legally  binding  instrument,  enforceable  in  accordance  with its terms,
     except in each case as the same may be limited by  bankruptcy,  insolvency,
     fraudulent  conveyance,  reorganization,  moratorium and other similar laws
     relating to or affecting creditors' rights generally,  by general equitable
     principles  (regardless  of  whether  enforceability  is  considered  in  a
     proceeding  in equity or at law) and by an implied  covenant  of good faith
     and fair dealing;  and the Debentures and the Indenture will conform in all
     material respects to the descriptions thereof in the Prospectus; and

          (g)  The  consummation  by  the  Company  of the  transactions  herein
     contemplated  and the  fulfillment of the terms hereof will not result in a
     breach of any of the terms or provisions of, or constitute a default under,
     the Company's  Articles of Incorporation or Bylaws,  as amended,  or of any
     indenture or other  agreement or  instrument  to which the Company is now a
     party.

                  SECTION 5.  Offering.  Forthwith  upon the  execution  of this
Underwriting   Agreement,   the   Representative,   acting   on  behalf  of  the
Underwriters,  shall  advise  the  Company  whether  a  public  offering  of the
Debentures  is to be made,  and,  if so,  shall  furnish to the  Company  (which
information shall be confirmed in writing as soon as practicable thereafter) (a)
the  information  with respect to such  offering of the  Debentures  and related
matters  that  is  required  to  complete  the  Prospectus   Supplement  or  any
post-effective amendment to the Registration Statement which may be required and
a copy of any "agreement among underwriters";  (b) if a post-effective amendment
to the  Registration  Statement is required,  a consent,  if  necessary,  to the
filing  of  the  post-effective  amendment  or an  acceptable  power-of-attorney
authorizing an available  individual to sign the consent on its behalf;  and (c)
such  further  information,  if any, as may be required to be  furnished  by the
Company under the Federal Power Act. Such information and the  power-of-attorney
may be provided by telecopier  (in the case of the  power-of-attorney,  followed
promptly by an executed copy).  Nothing in this Underwriting  Agreement shall be
construed to require that the  Underwriters  make any such public  offering on a
"fixed price" basis. The Representative  agrees to notify the Company in writing
of any change in the plan of distribution of the Debentures that would require a
supplement to the Prospectus or an amendment to the Registration Statement.

                  SECTION  6.  Time  and  Place  of  Closing.  Delivery  of  the
Debentures  and payment  therefor by check or checks,  payable to the Company or
its order, in New York, New York, or by wire transfer,  in immediately available
funds, shall be made at the offices of Winthrop,  Stimson, Putnam & Roberts, One
Battery Park Plaza,  New York, New York, at 10:00 A.M., New York time, on _____,
or at such other place,  time, and/or date as the Representative and the Company
may agree  upon in  writing  or as may be  established  in  accordance  with the
following  paragraph.  The hour and date of such delivery and payment are herein
called the "Closing Date."

                  The Debentures  shall be delivered to the  Representative  for
the  respective  accounts  of  the  Underwriters  in  registered  form  in  such
authorized  denominations and registered in such names as the Representative may
reasonably  request in writing at least two  business  days prior to the Closing
Date,  or,  to the  extent  not so  requested,  in the  names of the  respective
Underwriters in such denominations as the Company shall determine.

                  For the purpose of expediting  the checking of the  Debentures
by the  Representative,  the Company agrees to make the Debentures  available to
the  Representative for checking not later than 2:30 P.M., New York time, on the
last  business day  preceding  the Closing  Date,  at the New York office of The
First National Bank of Chicago, or at such other place, time, and/or date as may
be agreed upon between the Company and the Representative.

                  If any  Underwriter  shall fail or refuse  (otherwise than for
some reason  sufficient  to justify,  in accordance  with the terms hereof,  the
cancellation  or termination of its  obligations  hereunder) to purchase and pay
for the principal  amount of  Debentures  that it has agreed to purchase and pay
for hereunder,  the Company shall immediately give notice to the  Representative
of the default of such Underwriter,  and the other  Underwriters  shall have the
right  within  twenty-four  (24) hours  after the  receipt of such notice by the
Representative to determine to purchase,  or to procure one or more others,  who
are members of the National  Association of Securities  Dealers,  Inc.  ("NASD")
(or, if not members of the NASD, who are foreign banks, dealers, or institutions
not  registered  under the  Exchange Act and who agree in making sales to comply
with the NASD's Rules of Fair Practice),  and  satisfactory  to the Company,  to
purchase,  upon the terms herein set forth,  the principal  amount of Debentures
that the defaulting  Underwriter had agreed to purchase.  If any  non-defaulting
Underwriter  or  Underwriters  shall  determine  to  exercise  such  right,  the
Representative  shall give written  notice to the Company of such  determination
within  twenty-four  (24) hours after it shall have received  notice of any such
default,  and thereupon the Closing Date shall be postponed for such period, not
exceeding three business days, as the Company shall  determine.  If in the event
of such a default the  Representative  shall fail to give such notice,  or shall
within such twenty-four (24) hour period give written notice to the Company that
no other Underwriter or Underwriters,  or others, will exercise such right, then
this Underwriting  Agreement may be terminated by the Company,  upon like notice
given to the Representative,  within a further period of twenty-four (24) hours.
If in such  case the  Company  shall not elect to  terminate  this  Underwriting
Agreement, it shall have the right, irrespective of such default:

          (a) to require such  non-defaulting  Underwriters  to purchase and pay
     for the respective  principal amounts of Debentures that they had severally
     agreed to purchase hereunder,  as hereinabove  provided,  and, in addition,
     the principal  amount of Debentures that the defaulting  Underwriter  shall
     have so  failed to  purchase  up to a  principal  amount  thereof  equal to
     one-ninth  (1/9th) of the respective  principal  amounts of Debentures that
     such   non-defaulting   Underwriters  have  otherwise  agreed  to  purchase
     hereunder, and/or

          (b) to procure one or more others, who are members of the NASD (or, if
     not members of the NASD, who are foreign banks,  dealers,  or  institutions
     not  registered  under the  Exchange  Act and who agree in making  sales to
     comply with the NASD's Rules of Fair Practice), to purchase, upon the terms
     herein set forth,  the principal  amount of Debentures that such defaulting
     Underwriter  had  agreed to  purchase,  or that  portion  thereof  that the
     remaining  Underwriters  shall not be obligated to purchase pursuant to the
     foregoing clause (a).

In the event the Company  shall  exercise its rights under clause (a) and/or (b)
above,  the Company  shall give  written  notice  thereof to the  Representative
within such  further  period of  twenty-four  (24) hours,  and,  thereupon,  the
Closing Date shall be postponed for such period,  not exceeding  three  business
days, as the Company shall determine. In the event the Company shall be entitled
to but shall not elect to exercise  its rights  under clause (a) and/or (b), the
Company  shall  be  deemed  to  have  elected  to  terminate  this  Underwriting
Agreement.

                  Any action taken by the Company under this Section 6 shall not
relieve any defaulting  Underwriter  from liability in respect of any default of
such Underwriter under this Underwriting  Agreement.  Termination by the Company
under this  Section 6 shall be without any  liability on the part of the Company
or any  non-defaulting  Underwriter,  except as otherwise provided in subsection
(g) of Section 7.

                  In the  computation  of any period of  twenty-four  (24) hours
referred to in this  Section 6, there shall be excluded a period of  twenty-four
(24) hours in respect of each  Saturday,  Sunday,  or legal  holiday which would
otherwise be included in such period of time.

                  SECTION 7.  Covenants of the Company.  The Company agrees with
each of the Underwriters:

          (a) To deliver to the Representative a signed copy of the Registration
     Statement as originally filed and of all amendments thereto relating to the
     Debentures  or a  conformed  copy  thereof  certified  by an officer of the
     Company to be in the form filed.

          (b) To deliver to the Underwriters, through the Representative,  prior
     to 10:00  A.M.  New York time on the  business  day after the date on which
     this  Underwriting  Agreement  becomes  effective  as  many  copies  of the
     Prospectus as the Representative may reasonably request.

          (c) To cause the Prospectus to be filed with the  Commission  pursuant
     to and in  compliance  with Rule  424,  and to  advise  the  Representative
     promptly of the  issuance of any stop order under the  Securities  Act with
     respect to the Registration Statement or the institution of any proceedings
     therefor of which the Company shall have received notice.  The Company will
     use its best  efforts to prevent the issuance of any such stop order and to
     secure the prompt removal thereof if issued.

          (d) During such period of time (not  exceeding  nine months) after the
     Prospectus has been filed with the  Commission  pursuant to Rule 424 as the
     Underwriters  are  required  by law to deliver a  prospectus,  if any event
     relating  to or  affecting  the  Company or of which the  Company  shall be
     advised in writing by the Representative shall occur which in the Company's
     opinion  should be set forth in a supplement or amendment to the Prospectus
     in order to make the statements  therein, in the light of the circumstances
     when the  Prospectus  is delivered to a purchaser  of the  Debentures,  not
     misleading,  to notify  the  Representative  of such  event and to amend or
     supplement  the  Prospectus  by either (i)  preparing  and filing  with the
     Commission and furnishing to the  Representative at the Company's expense a
     reasonable  number of copies of a supplement or supplements or an amendment
     or  amendments  to the  Prospectus  or (ii)  making an  appropriate  filing
     pursuant  to  Section  13,  14, or 15(d) of the  Exchange  Act,  which will
     supplement or amend the Prospectus so that, as supplemented or amended,  it
     will not contain an untrue  statement of a material fact or omit to state a
     material fact  required to be stated  therein or necessary in order to make
     the  statements  therein,  in the  light  of  the  circumstances  when  the
     Prospectus is delivered to a purchaser of the  Debentures,  not misleading;
     provided that should such event relate  solely to the  activities of any of
     the  Underwriters,  then the  Underwriters  shall  assume  the  expense  of
     preparing any such  amendment or  supplement.  In case any  Underwriter  is
     required to deliver a prospectus  after the  expiration of nine months from
     the date the Prospectus is filed with the Commission  pursuant to Rule 424,
     the Company,  upon the request of the  Representative,  will furnish to the
     Representative,  at the expense of such Underwriter,  a reasonable quantity
     of a supplemented or amended prospectus or supplements or amendments to the
     Prospectus complying with Section 10(a) of the Securities Act.

          (e) During such period of time after the date the  Prospectus is filed
     with the  Commission  pursuant to Rule 424 as a prospectus  relating to the
     Debentures is required to be delivered  under the  Securities  Act, to file
     promptly all documents required to be filed with the Commission pursuant to
     Section 13, 14, or 15(d) of the Exchange Act.

          (f) To make generally  available to the Company's  security holders as
     soon as  practicable  an earning  statement  (which need not be audited) in
     reasonable  detail  covering a period of at least twelve  months  beginning
     after the "effective date of the registration statement" within the meaning
     of Rule 158 under the Securities  Act, which earning  statement shall be in
     such form,  and be made generally  available to security  holders in such a
     manner,  as to  comply  with  the  requirements  of  Section  11(a)  of the
     Securities Act and Rule 158 promulgated under the Securities Act.

          (g) Except as herein otherwise provided, to pay all expenses and taxes
     (except  transfer  taxes) in connection with (i) the preparation and filing
     of  the  Registration  Statement  and  any  amendments  thereto,  (ii)  the
     issuance,  printing, and delivery of the Debentures, (iii) any fees charged
     by  securities  rating  services  for  rating the  Debentures  and (iv) the
     typing,   printing,   and  delivery  to  the   Underwriters,   through  the
     Representative,  of  reasonable  quantities  of copies of the  Registration
     Statement and the  Prospectus,  and any  amendment or  supplement  thereto,
     except as otherwise provided in paragraph (d) of this Section.  The Company
     shall not,  however,  be required to pay any amount for any expenses of the
     Representative   or  any  of  the   Underwriters,   except  that,  if  this
     Underwriting   Agreement   shall  be  terminated  in  accordance  with  the
     provisions  of  Section  8,  9,  or 11,  the  Company  will  reimburse  the
     Representative for (i) the reasonable fees and disbursements of counsel for
     the Underwriters,  whose fees and  disbursements the Underwriters  agree to
     pay in any other event, and (ii) their reasonable  out-of-pocket  expenses,
     in an amount  not  exceeding  a total of ten  thousand  dollars  ($10,000),
     incurred  in  contemplation   of  the  performance  of  this   Underwriting
     Agreement.  The  Company  shall  not in any  event be  liable to any of the
     Underwriters for damages on account of loss of anticipated profits.

          (i) Not to sell  any  additional  Subordinated  Debentures  until  the
     earlier to occur of (i) the Closing  Date or (ii) in the case of an initial
     public  offering  at a fixed  price  by the  Underwriters,  the date of the
     termination  of the fixed price  offering  restrictions  applicable  to the
     Underwriters.  The  Representative  agrees to notify  the  Company  of such
     termination if it occurs prior to the Closing Date.

                  SECTION  8.  Conditions  of  Underwriters'  Obligations.   The
obligation of the  Underwriters to purchase and pay for the Debentures  shall be
subject to the accuracy of the representations and warranties made herein on the

          (c) The authorization by the Federal Energy  Regulatory  Commission of
     the issuance and sale of the Debentures shall be in full force and effect;

     of Counsel for the Underwriters, and (ii) if the Prospectus relating to the

     information  is given in the  Prospectus,  as it may have been  amended  or
     supplemented,  there  has not  been  any  material  adverse  change  in the
     business, property, or financial condition of the Company and there has not
     been any  material  transaction  entered  into by the  Company,  other than

     Underwriter and each person who controls any Underwriter within the meaning
     of Section 15 of the  Securities  Act from and  against any and all losses,
     claims, damages, or liabilities,  joint or several, to which they or any of

     common  law.  The  Company  shall  reimburse  each  such   Underwriter  and
     controlling  person  for any  legal or other  expenses  (including,  to the
     extent  hereinafter  provided,  reasonable  counsel fees) incurred by them,
     such  reimbursement  to be made as such  expenses are incurred by them,  in
     connection  with  investigating  any  such  losses,  claims,   damages,  or
     liabilities or in connection  with  defending any actions,  insofar as such
     losses, claims, damages, liabilities,  expenses, or actions arise out of or
     are based  upon any  untrue  statement  or alleged  untrue  statement  of a
     material fact  contained in a preliminary  prospectus (if used prior to the
     initial  effective  date of the  Registration  Statement),  or in the Basic
     Prospectus (if used prior to the date that the Prospectus is filed with the
     Commission  pursuant to Rule 424) or in the  Registration  Statement or the
     Prospectus,  as amended or  supplemented  (if any amendments or supplements
     thereto shall have been made), or the omission or alleged omission to state
     therein a material fact required to be stated  therein or necessary to make
     the statements therein, in light of the circumstances under which they were
     made  not  misleading;  provided,  however,  that the  indemnity  agreement
     contained in this  paragraph  shall not apply to any such  losses,  claims,
     damages,  liabilities,  expenses, or actions arising out of, or based upon,
     any such untrue statement or alleged untrue statement, or any such omission
     or alleged  omission,  if such  statement  or omission was made in reliance
     upon and in conformity with written information furnished to the Company by
     or through the  Representative  on behalf of any Underwriter  expressly for
     use in connection with the preparation of the Registration Statement or the
     Prospectus or any amendment or supplement to either thereof, or arising out
     of,  or based  upon,  statements  in or  omissions  from  that  part of the
     Registration  Statement which shall constitute the statement of eligibility
     under the Trust  Indenture  Act of the  Trustee  under the  Indenture;  and
     provided further,  that the indemnity agreement contained in this paragraph
     shall  not  inure  to the  benefit  of  any  Underwriter  or of any  person
     controlling any Underwriter on account of any such losses, claims, damages,
     liabilities,  expenses,  or actions arising from the sale of the Debentures
     to any person if there  shall not have been given or sent to such person on
     behalf of such Underwriter (i) with or prior to the written confirmation of
     the  sale to such  person  a copy of the  Prospectus,  as then  amended  or
     supplemented  (exclusive  for this purpose of any  amendment or  supplement
     relating  solely  to  any  offering  of  debt  securities  other  than  the
     Debentures  and of any document  which  becomes  incorporated  by reference
     pursuant to Item 12 of Form S-3 more than 3 business days prior to the date
     hereof),  and (ii) as soon as available  after such written  confirmation a
     copy of any amendment or supplement to the  Prospectus  (exclusive for this
     purpose of any document  incorporated  by reference  pursuant to Item 12 of
     Form  S-3)  which  the  Company  shall  thereafter  furnish,   pursuant  to
     subsection (d) of Section 7 hereof, relating to an event occurring prior to
     the payment for and delivery to such person of the  Debentures  involved in
     such sale. The indemnity agreement of the Company contained in this Section
     and the  representations and warranties of the Company contained in Section
     4 shall remain  operative  and in full force and effect  regardless  of any
     investigation  made  by or  on  behalf  of  any  Underwriter  or  any  such
     controlling person, and shall survive the delivery of the Debentures.

          (b) Each Underwriter  shall indemnify,  defend,  and hold harmless the
     Company,  its directors  and officers,  and each person who controls any of
     the foregoing  within the meaning of Section 15 of the Securities Act, from
     and against any and all losses, claims,  damages, or liabilities,  joint or
     several,  to  which  they or any of  them  may  become  subject  under  the
     Securities Act or any other statute or common law and shall  reimburse each
     of  them  for  any  legal  or  other  expenses  (including,  to the  extent
     hereinafter  provided,  reasonable  counsel  fees)  incurred by them,  such
     reimbursement  to be  made  as such  expenses  are  incurred  by  them,  in
     connection  with  investigating  any  such  losses,  claims,   damages,  or
     liabilities  or in connection  with  defending any action,  insofar as such
     losses, claims, damages, liabilities,  expenses, or actions arise out of or
     are based  upon any  untrue  statement  or alleged  untrue  statement  of a
     material fact contained in the Registration Statement or the Prospectus, as
     amended or  supplemented  (if any amendments or  supplements  thereto shall
     have been furnished),  or the omission or alleged omission to state therein
     a material  fact  required to be stated  therein or  necessary  to make the
     statements  therein not misleading,  if such statement or omission was made
     in reliance upon and in conformity  with written  information  furnished to
     the Company by or through the  Representative on behalf of such Underwriter
     expressly for use in connection  with the  preparation of the  Registration
     Statement  or the  Prospectus  or any  amendment  or  supplement  to either
     thereof. The indemnity agreement of the respective  Underwriters  contained
     in this  paragraph  shall  remain  operative  and in full  force and effect
     regardless of any  investigation  made by or on behalf of the Company,  its
     directors or officers,  or any such controlling  person,  and shall survive
     the delivery of the Debentures.

          (c) The  Company  and the several  Underwriters  each shall,  upon the
     receipt  of notice of the  commencement  of any  action  against  it or any
     person  controlling it as aforesaid,  in respect of which  indemnity may be
     sought on account of any indemnity  agreement  contained  herein,  promptly
     give  written  notice of the  commencement  thereof to the party or parties
     against whom indemnity  shall be sought  hereunder,  but the omission so to
     notify  the  indemnifying  party or parties  of any such  action  shall not
     relieve the  indemnifying  party or parties from any liability  which it or
     they may have to the  indemnified  party  otherwise than on account of such
     indemnity  agreement.  In case such notice of any such  action  shall be so
     given, the  indemnifying  party shall be entitled to participate at its own
     expense in the defense or, if it so elects,  to assume (in conjunction with
     any other  indemnifying  parties) the defense of the action, in which event
     the defense shall be conducted by counsel chosen by such indemnifying party
     or parties and  satisfactory to the indemnified  party or parties who shall
     be a defendant or defendants in the action,  and the indemnified  defendant
     or defendants  shall bear the fees and expenses of any  additional  counsel
     retained by them; but if the  indemnifying  party shall elect not to assume
     the  defense of the  action,  the  indemnifying  party will  reimburse  the
     indemnified  party or parties for the  reasonable  fees and expenses of any
     counsel retained by the indemnified  party or parties.  If the indemnifying
     party does not employ  counsel to take  charge of the defense or if counsel
     for the indemnified  party reasonably  concludes that there may be defenses
     available to the indemnified  party which are different from or in addition
     to  those  available  to  the   indemnifying   party  (in  which  case  the
     indemnifying  party will not have the right to assume the defense on behalf
     of the indemnified party),  legal expenses (limited to those of one counsel
     for all indemnified  parties) and other expenses reasonably incurred by the
     indemnified party will be paid by the indemnifying  party. No party will be
     liable  with  respect to any  settlement  made  without  its prior  written
     consent.

          (d)  If  the  indemnification  provided  for  in  this  Section  10 is
     unavailable to hold harmless an indemnified  party under  subsection (a) or
     (b) above in respect of any  losses,  claims,  damages or  liabilities  (or
     actions in respect  thereof)  referred to therein,  then each  indemnifying
     party shall  contribute  to the amount paid or payable by such  indemnified
     party as a result  of such  losses,  claims,  damages  or  liabilities  (or
     actions in respect thereof) in such proportion as is appropriate to reflect
     the relative fault of the Company on the one hand and the  Underwriters  on
     the other in connection  with the statements or omissions which resulted in
     such losses, claims, damages or liabilities (or actions in respect thereof)
     as well as any other relevant equitable considerations.  The relative fault
     shall be determined by reference to, among other things, whether the untrue
     or alleged untrue  statements of a material fact or the omission or alleged
     omission to state a material  fact relates to  information  supplied by the
     Company on the one hand or the  Underwriters  on the other and the parties'
     relative  intent,  knowledge,  access to  information  and  opportunity  to
     correct or  prevent  such  statements  or  omission.  The  Company  and the
     Underwriters  agree that it would not be just and equitable if contribution
     pursuant to this  subsection  (d) were  determined  by pro rata  allocation
     (even if the  Underwriters  were treated as one entity for such purpose) or
     by any other method of allocation  which does not take account of equitable
     considerations referred to above in this subsection (d). The amount paid or
     payable by an indemnified party as a result of the losses,  claims, damages
     or liabilities  (or actions in respect  thereof)  referred to above in this
     subsection  (d)  shall be  deemed to  include  any legal or other  expenses
     reasonably   incurred  by  such   indemnified   party  in  connection  with
     investigating  or defending any such action or claim.  Notwithstanding  the
     provisions  of this  subsection  (d), no  Underwriter  shall be required to
     contribute  any amount in excess of the amount by which the total  price at
     which the Debentures  underwritten by it and distributed to the public were
     offered  to the  public  exceeds  the  amount  of any  damages  which  such
     Underwriter  has otherwise been required to pay by reason of such untrue or
     alleged untrue statement or omission or alleged omission.  No person guilty
     of fraudulent misrepresentation (within the meaning of Section 11(f) of the
     Securities Act) shall be entitled to  contribution  from any person who was
     not  guilty  of  such  fraudulent   misrepresentation.   The  Underwriters'
     obligations in this  subsection (d) to contribute are several in proportion
     to their respective underwriting obligations and not joint.

          (e) The  respective  obligations  of the Company and the  Underwriters
     under this Section 10 shall be in addition to any  liability  which each of
     them may otherwise have.

                  SECTION 11.  Termination.  This Underwriting  Agreement may be
terminated at any time prior to the Closing Date by the Representative  with the
consent of the  Underwriters,  who may  include the  Representative,  which have
agreed to purchase in the aggregate fifty percent (50%) or more of the aggregate
principal  amount of the  Debentures,  if,  prior to such time,  (i)  trading in
securities on the New York Stock Exchange  shall have been generally  suspended,
(ii) minimum or maximum ranges for prices shall have been generally  established
on the New York Stock Exchange by the New York Stock  Exchange,  the Commission,
or other governmental  authority,  (iii) a general banking moratorium shall have
been  declared  by federal or New York State  authorities,  (iv) an  outbreak or
escalation of hostilities or other national or international  calamity or crisis
occurs,  the effect of which on the  financial  markets of the United  States is
such  as,  in  the  reasonable  judgment  of  the  Representative,  to  make  it
impracticable to market the Debentures or enforce  contracts for the sale of the
Debentures or (v) in the reasonable judgment of the Representative,  the subject
matter of any  amendment  or  supplement  (prepared by the Company) to the Basic
Prospectus, the Registration Statement or the Prospectus (except for information
relating to the public  offering  of the  Debentures  or to the  activity of any
Underwriter or  Underwriters)  filed or issued after the  effectiveness  of this
Underwriting  Agreement  by the  Company  shall  have  materially  impaired  the
marketability of the Debentures. Any termination hereof pursuant to this Section
11 shall be  without  liability  of any  party to any  other  party,  except  as
otherwise provided in subsection (h) of Section 7.

                  SECTION 12.  Applicable Law. This  Underwriting  Agreement and
the  Debentures  to be sold  hereunder  shall be New York  contracts,  and their
validity  and  interpretation  shall be governed by the laws of the State of New
York.

                  SECTION 13.  Successors.  This  Underwriting  Agreement  shall
inure to the benefit of the Company,  the Underwriters  and, with respect to the
provisions  of Section  10,  each  director,  officer,  and  controlling  person
referred to in Section 10, and their  respective  successors.  Nothing herein is
intended or shall be construed to give to any other person, firm, or corporation
any legal or  equitable  right,  remedy,  or claim  under or in  respect  of any
provision in this Underwriting  Agreement.  The term "successor" as used in this
Underwriting  Agreement shall not include any purchaser,  as such purchaser,  of
any of the Debentures from any of the Underwriters.

                  SECTION  14.  Notices.  All communications  hereunder shall be
in writing  and, if to the  Underwriters,  shall be mailed or  delivered  to the
Representative  at the address set forth below, or, if to the Company,  shall be
mailed or delivered to it c/o IES Utilities Inc., 200 First Street,  S.E., Cedar
Rapids, Iowa 52401 Attention: Treasurer.

                  SECTION 15. Counterparts.  This Underwriting  Agreement may be
executed  in any  number of  counterparts  and by  different  parties  hereto on
separate  counterparts,   each  of  such  counterparts,  when  so  executed  and
delivered,  shall be  deemed  to be an  original,  and all of such  counterparts
shall, taken together, constitute one and the same agreement.

                                   -----------

                  The stated interest rate to be borne by the Debentures and the
price  to be  paid  to the  Company  therefor  (stated  as a  percentage  of the
principal  amount of the  Debentures),  in each case are set forth in Schedule I
hereto. If said interest rate and price and this  Underwriting  Agreement are in
accordance  with your  understanding  of our  agreement,  please  indicate  your
acceptance thereof in the space provided below for that purpose; whereupon, this
letter and your  acceptance  shall  constitute a binding  agreement  between the
Company and the several Underwriters in accordance with its terms.


                               Very truly yours,

                               As Representative(s) of the Underwriters

Re: __% Subordinated Debentures, Series ___
    $
    Due

Ladies and Gentlemen:

                  I am counsel for IES  Industries  Inc.,  the parent company of
IES Utilities  Inc. (the  "Company") and have  participated  in the issuance and
sale by the Company to you of $ aggregate  principal  amount of __% Subordinated
Debentures,  Series ___ due _____________ (the  "Debentures"),  issued under the
Company's  Indenture (For Unsecured  Subordinated Debt Securities),  dated as of
December  1, 1995,  to The First  National  Bank of  Chicago,  as  Trustee  (the
"Trustee") (the "Indenture")  pursuant to an Underwriting  Agreement dated as of
________ between you and the Company (the "Underwriting Agreement").

                  In this connection,  I have examined,  among other things, the
following:

          (a) the  Registration  Statement and the Prospectus (such terms having
     the same meanings herein as in the Underwriting Agreement);

          (b) the Articles of  Incorporation  of the Company and all  amendments
     thereto, as certified by the Secretary of State of the State of Iowa;

          (c) a Certificate of the Secretary of State or other appropriate state
     official  certifying  as to the  good  standing  and  qualification  of the
     Company to transact business in the State of Iowa;

          (d) the By-laws of the  Company,  certified  by the  Secretary  of the
     Company;

          (e) the Indenture;

          (f) resolution of the Board of Directors of the Company [pertaining to
     the authorization and sale of the Debentures and related matters];

          (g) the  Application  filed by the  Company  with the  Federal  Energy
     Regulatory  Commission  seeking,  among  other  things,  authority  for and
     approval of the issuance and sale of Debentures and a copy of the Letter of
     Authority  issued  by  the  Chief  Accountant  of  such  Commission,  dated
     __________,  authorizing  and  approving  the  issuance  and  sale  of  the
     Debentures;

          (h) certified copies of the Officer's Certificate of the Company dated
     __________,  setting  forth  the  terms and  conditions  of the  Debentures
     approved by the __________ of the Company.

          (i) counterparts of the Underwriting Agreement executed by you and the
     Company; and

          (j) other information, documents, and material which I deem sufficient
     along with the foregoing to support this opinion.

                  In addition,  in connection with this opinion, I have reviewed
various  orders  and  certificates  of, and  members  of the legal  staff of IES
Industries Inc. had telephone  conversations with, public officials.  I have not
examined the Debentures, except a specimen thereof.


<PAGE>

                  Subject to the  foregoing  and to the further  exceptions  and
qualifications  set forth  below  and  having  regard  to all legal and  factual
considerations  which I deem relevant and based upon all such other  information
and documents furnished to or obtained by me as I believe necessary to enable me
to render this opinion,  including certificates of public officials, I am of the
opinion that:

     1. The Company has been duly  incorporated  and is validly  existing and in
good  standing as a corporation  under the laws of the State of Iowa,  with full
power and authority (corporate and other) to own its property and to conduct its
business as presently being conducted all within the State of Iowa.

     2. The Debentures and the Indenture conform in all material respects to the
descriptions thereof in the Prospectus.

     3. The  Underwriting  Agreement  has been  duly  authorized,  executed  and
delivered on behalf of the Company.

     4. The  Debentures  have  been duly  authorized  and,  when duly  executed,
authenticated,  issued and delivered to and paid for by you in  accordance  with
the terms of the  Underwriting  Agreement,  will  constitute  valid and  legally
binding  obligations  of the  Company  entitled  to the  benefits  and  security
provided by the Indenture,  enforceable  against the Company in accordance  with
their  terms  except  as the  same may be  limited  by  bankruptcy,  insolvency,
fraudulent conveyance, reorganization, moratorium or other similar laws relating
to  or  affecting  enforcement  of  creditors'  rights  generally,   by  general
principles of equity  (regardless of whether or not enforceability is considered
in a  proceeding  in equity or at law) and by an implied  covenant of good faith
and fair dealing.

     5. The  Indenture  has been duly and validly  authorized  by all  necessary
corporate  action of the  Company,  has been  duly  executed,  acknowledged  and
delivered  by  the  Company  and  is a  valid  and  legally  binding  instrument
enforceable  against the Company in accordance with its terms except as the same
may be limited by bankruptcy, insolvency, fraudulent conveyance, reorganization,
moratorium  or other  similar  laws  relating  to or  affecting  enforcement  of
creditors'  rights  generally,  by general  principles of equity  (regardless of
whether enforceability is considered in a proceeding in equity or at law) and by
an implied covenant of good faith and fair dealing.

     6.  The  execution  and  delivery  of  the  Underwriting   Agreement,   the
consummation of the transactions therein contemplated and the fulfillment of the
terms  thereof do not and will not conflict  with, or result in a breach by, the
Company of any of the terms or provisions of, or constitute a default under, the
Articles of Incorporation or By-laws of the Company or the Indenture,  or to the
best of my  knowledge  after  reasonable  investigation,  any  other  indenture,
mortgage, deed of trust or other agreement or instrument to which the Company is
a party  or by  which  it or any of its  properties  are  bound,  including  the
Agreement and Plan of Merger,  by and among, WPL Holdings,  Inc., IES Industries
Inc., Interstate Power Company (a Delaware  corporation),  WPLH Acquisition Co.,
and Interstate Power Company (a Wisconsin corporation), dated as of November 10,
1995, as amended.

     7.  The  Chief  Accountant  of the  Federal  Energy  Regulatory  Commission
("FERC")  has  authorized  the  issuance  and  sale  of  the  Debentures,  which
authorization  is, to the best of my knowledge,  still in full force and effect;
the issuance  and sale of the  Debentures  to you  pursuant to the  Underwriting
Agreement is in conformity  with the terms of such  authorization;  and no other
authorization,  approval  or consent of any other  governmental  body is legally
required  for  the  issuance  and  sale  of  the  Debentures   pursuant  to  the
Underwriting  Agreement,  except such as have been obtained under the Securities
Act of 1933, as amended  ("Securities  Act"),  and such as may be required under
state  securities  or  blue  sky  laws  in  connection  with  the  purchase  and
distribution of the Debentures by you.

     8. The Company  has the legal right to function  and operate as an electric
and gas  utility in the state of Iowa,  holds  valid and  subsisting  franchises
authorizing  it to carry on the  utility  business in which it is engaged in all
incorporated  communities  having a population of 1,000 or more (except in ____,
which operations have not been impaired by the lack ofsuch franchises),  and has
adaquate licenses and permits where required by law to maintain electric and gas
transmission and distribution lines through unincorporated areas and over public
lands not located in incorporated  communities and over private rights-of-way in
the territory which it serves.

     9. Except as referred to in the Registration  Statement and Prospectus,  to
the  best  of  my  knowledge,  there  are  no  material  or  contemplated  legal
proceedings  to which the  Company is or may be a party or of which  property of
the  Company  is or may be  subject  which  depart  from  the  ordinary  routine
litigation incident to the kinds of business conducted by the Company.

     10. The documents  incorporated by reference in the Prospectus  (other than
the  financial  statements  and financial  and  statistical  data, as to which I
express  no  opinion),  when they were filed with the  Securities  and  Exchange
Commission (the "Commission"), complied as to form in all material respects with
the  requirements  of the  Securities  Exchange  Act of 1934 and the  rules  and
regulations  thereunder of the Commission;  and I have no reason to believe that
any of such documents, when they were so filed, contained an untrue statement of
a material fact or omitted to state a material  fact  necessary in order to make
the statements  therein, in the light of the circumstances under which they were
made when such documents were so filed, not misleading.

     11.  To  the  best  of my  knowledge,  there  are  no  contracts  or  other
instruments  or documents  of a character  required to be filed as an exhibit to
the Registration  Statement or required to be incorporated by reference into the
Prospectus  or required to be  described  in the  Registration  Statement or the
Prospectus  which are not filed or  incorporated  by  reference  or described as
required.

                  I am a member  of the bar of the State of Iowa and do not hold
myself out as an expert on the laws of any other  State.  The  opinion set forth
above is solely for the benefit of the  addressees of this letter and may not be
relied upon in any manner by any other person without my prior written  consent,
except that Winthrop,  Stimson,  Putnam & Roberts may rely on this opinion as to
all matters of Iowa law in  rendering  their  opinions  required to be delivered
under the Underwriting Agreement.

                                                       Very truly yours,

Re: IES Utilities Inc.
    $             % Subordinated Debentures,
    Series        Due


Ladies and Gentlemen:

                  We have acted as Counsel for IES Utilities Inc. ("Company") in
connection  with the  issuance  and sale by the  Company to you  pursuant to the
Underwriting Agreement dated _________,  ("Underwriting  Agreement") between the
Company and you, of $ in principal amount of % Subordinated  Debentures,  Series
__ (the "Debentures"), issued under the Company's Indenture dated as of December
1, 1995, to The First National Bank of Chicago,  as Trustee (the "Trustee") (the
"Indenture").

                  We are members of the New York Bar and,  for  purposes of this
opinion,  do not hold  ourselves out as experts on the laws of any  jurisdiction
other than the State of New York and the United States of America. We have, with
your consent,  relied upon the opinion of even date herewith addressed to you by
__________,  Counsel for IES Industries  Inc., as to the matters covered in such
opinion  relating to Iowa law. We have reviewed said opinion and believe that it
is satisfactory and that you and we are justified in relying thereon.

                  We also examined such other documents and questions of law and
satisfied  ourselves  as to such other  matters as we have deemed  necessary  in
order to  enable  us to  express  this  opinion.  We have not  examined  and are
expressing no opinion or belief as to matters  relating to the  incorporation of
the  Company.  We also  have not  examined  the  Debentures,  except a  specimen
thereof.  As to various  questions  of fact  material to this  opinion,  we have
relied upon  representations and certificates of officers and representatives of
the  Company  and   statements  in  the   Registration   Statement   (the  terms
"Registration  Statement"  and  "Prospectus,"  as used  herein,  have  the  same
meanings as those words in the  Underwriting  Agreement).  We have also examined
originals,  or  copies  of  originals  certified  to our  satisfaction,  of such
agreements, documents, certificates and other instruments, as we have considered
relevant and necessary as a basis for such opinion. In such examination, we have
assumed the  genuineness of all  signatures,  the  authenticity of all documents
submitted  to us as  originals,  and  the  conformity  to the  originals  of the
documents submitted to us as certified or photostatic copies.


<PAGE>


                  Subject to the  foregoing  and to the further  exceptions  and
qualifications set forth below, we are of the opinion that:

                  1. The Indenture  has been duly and validly  authorized by all
necessary corporate action of the Company, has been duly executed,  acknowledged
and  delivered  by the  Company and is a valid and  legally  binding  instrument
enforceable  against the Company in accordance  with its terms except as limited
by bankruptcy, insolvency, fraudulent conveyance, reorganization,  moratorium or
other similar laws  relating to or affecting  enforcement  of creditors'  rights
generally, by general principles of equity (regardless of whether enforceability
is considered in a proceeding in equity or at law) and by an implied covenant of
good faith and fair dealing; and the Indenture has been duly qualified under the
Trust Indenture Act of 1939, as amended (the "Trust Indenture Act").

                  2. The  Debentures  have been duly  authorized  and, when duly
executed,  authenticated,  issued  and  delivered  to  and  paid  for  by you in
accordance with the terms of the Underwriting  Agreement,  will constitute valid
and legally  binding  obligations  of the Company  entitled to the  benefits and
security provided by the Indenture enforceable against the Company in accordance
with their terms  except as the same may be limited by  bankruptcy,  insolvency,
fraudulent conveyance, reorganization, moratorium or other similar laws relating
to  or  affecting  enforcement  of  creditors'  rights  generally,   by  general
principles of equity  (regardless of whether  enforceability  is considered in a
proceeding  in equity or at law) and by an  implied  covenant  of good faith and
fair dealing.

                  3.  The  summaries  of the  terms  of the  Indenture  and  the
Debentures  contained in the  Registration  Statement and the Prospectus  fairly
describe  in  all  material  respects  the  provisions  thereof  required  to be
described by the registration statement form.

                  4.  The Underwriting  Agreement has been duly  authorized,  
executed and delivered on behalf of the Company.

                  5. The execution and delivery of the  Underwriting  Agreement,
the consummation of the transactions therein contemplated and the fulfillment of
the terms  thereof do not and will not conflict  with, or result in a breach by,
the Company of any of the terms or provisions of, or constitute a default under,
the  Articles of  Incorporation  or By-laws of the Company or to the best of our
knowledge,  any other indenture,  mortgage,  deed of trust or other agreement or
instrument  to  which  the  Company  is a  party  or by  which  it or any of its
properties  are bound.  As used in this  paragraph 5, the phrase "to the best of
our knowledge  after  reasonable  investigation"  is intended to mean the actual
knowledge  or  information  known by the  lawyers  in our  firm  who  have  been
principally  involved  in the  transactions  contemplated  by  the  Underwriting
Agreement.

                  6. The  Chief  Accountant  of the  Federal  Energy  Regulatory
Commission  has  authorized  the  issuance  and  sale of the  Debentures,  which
authorization is, to the best of our knowledge,  still in full force and effect;
the issuance  and sale of the  Debentures  to you  pursuant to the  Underwriting
Agreement is in conformity  with the terms of such  authorization;  and no other
authorization, approval or consent of any other federal commission or regulatory
authority  is  legally  required  for the  issuance  and sale of the  Debentures
pursuant to the Underwriting Agreement,  except such as have been obtained under
the Securities Act of 1933, as amended ("Securities Act") or the Trust Indenture
Act.

                  7. To the best of our knowledge,  the  Registration  Statement
is, at the date hereof,  effective  under the  Securities  Act and no stop order
suspending the  effectiveness of the Registration  Statement has been issued and
no proceedings for a stop order with respect thereto have been instituted or are
pending or threatened under the Securities Act; the Registration  Statement,  at
the time of its effectiveness,  and the Prospectus, at the time first filed with
the Securities and Exchange Commission ("Commission") pursuant to Rule 424 under
the  Securities  Act,  complied  as to form in all  material  respects  with the
requirements  of the  Securities  Act  and  the  Trust  Indenture  Act,  and the
applicable  rules and regulations of the Commission  thereunder  (except that we
express  no  opinion  as to the  financial  statements  or  other  financial  or
statistical data included or incorporated by reference therein or as to the Form
T-1 filed as an exhibit to the Registration Statement).

                  8. The  Company  and IES  Industries  Inc.  are  exempt  from 
regulation  under the Public  Utility  Holding  Company Act of 1935, as amended,
except under Section 9(a)(2) thereof.

                  9. To the best of our  knowledge,  there are no  contracts  or
other instruments or documents of a character required to be filed as an exhibit
to the  Registration  Statement or required to be incorporated by reference into
the Prospectus or required to be described in the Registration  Statement or the
Prospectus  which are not filed or  incorporated  by  reference  or described as
required.

                  In passing upon the forms of the  Registration  Statement  and
the Prospectus,  we necessarily  assume the correctness and  completeness of the
statements made by the Company and the  information  included or incorporated by
reference  in  the  Registration  Statement  and  the  Prospectus  and  take  no
responsibility  therefor,  except insofar as such statements relate to us and as
set forth in  paragraph  3 above.  In  connection  with the  preparation  of the
Registration Statement and the Prospectus,  we have had discussions with certain
of the  Company's  officers  and  representatives,  with other  counsel  for the
Company,  with your  counsel  and with  Arthur  Andersen  LLP,  the  independent
certified public  accountants who examined  certain of the financial  statements
included  or  incorporated  by  reference  in the  Registration  Statement.  Our
examination of the Registration Statement and the Prospectus and our discussions
did not disclose to us any information  that gives us reason to believe that the
Registration  Statement,  at the time it became  effective,  contained an untrue
statement of a material  fact or omitted to state a material fact required to be
stated therein or necessary to make the statements  therein not  misleading,  or
that the  Prospectus,  at the time first filed with the  Commission  pursuant to
Rule 424 under the Securities Act and at the date hereof,  contained or contains
an untrue  statement of a material  fact or omitted or omits to state a material
fact  necessary  in order to make the  statements  therein,  in the light of the
circumstances under which they were made, not misleading.  We do not express any
opinion  or  belief  as to  the  financial  statements  or  other  financial  or
statistical  data  included or  incorporated  by reference  in the  Registration
Statement or the Prospectus.  We do not express any opinion as to the statements
contained in the Form T-1 filed as an exhibit to the Registration Statement.

                  The  opinion  set forth above is solely for the benefit of the
addressees  hereof  in  connection  with  the  Underwriting  Agreement  and  the
transactions  contemplated  thereunder and may not be quoted or furnished to, or
relied upon in any manner by, any other person or utilized for any other purpose
without our prior written consent.

                                            Very truly yours,

agreements or  instruments  have been duly  authorized  by all requisite  action
(corporate  or other),  executed  and  delivered  by such  parties and that such

such parties.  As to questions of fact material to our opinions,  we have relied
on certificates of officers of the Company and of public officials.

                  Certain of our opinions  expressed below as to factual matters
are qualified as being limited "to the best of our  knowledge" or by other words

Underwriting  Agreement.  In rendering such opinions,  we have not conducted any
independent  investigation  or consulted  with other  attorneys in our firm with
respect to the matters covered thereby.

                  On the basis of such  examination,  we adivse you that, in our

Company and  (assuming  the  Indenture  has been duly  authorized,  executed and
delivered by the Trustee)  consititues a valid and legally binding obligation of
the Company enforceable against the Company in accordance with its terms, except
as the same may be limited by  bankruptcy,  insolvency,  fraudulent  conveyance,
reorganization,  moratorium  or other  similar  laws  relating  to or  affecting
enforcement  of creditors'  rights  generally,  by general  principles of equity
(regardless of whether enforceability is considered in a proceeding in equity or
at law) and by an implied covenant of good faith and fair dealing;

     4. the Indenture has been duly qualified  under the Trust  Indenture Act of
1939, as amended ("Trust Indenture Act");

     5. the  Debentures  have been duly  authorized  and executed by the Company
and,  when  authenticated  by the  Trustee in  accordance  with the terms of the
Indenture,  and delivered to and paid for by you in accordance with the terms of
the Underwriting Agreement, will constitute valid and binding obligations of the
Company entitled to the benefits and security provided by the Indenture,  except
as the same may be limited by  bankruptcy,  insolvency,  fraudulent  conveyance,
reorganization,  moratorium  or other  similar  laws  relating  to or  affecting
enforcement  of creditors'  rights  generally,  by general  principles of equity

at law) and by an implied covenant of good faith and fair dealing;

our knowledge,  no stop order  suspending the  effectiveness of the Registration

                      [Letterhead of Dorsey & Whitney LLP]


                                                              [Date]


Re:  IES Utilities Inc.
         $             % Subordinated Debentures,
         Series


Ladies and Gentlemen:

                  This letter relates to the  registration  under the Securities
Act of 1933, as amended (the "Act"),  and offering of  $__________  in aggregate
principal amount of ___% Subordinated Debentures, Series ____ (the "Debentures")
of IES Utilities Inc., an Iowa  corporation  (the  "Company").  The registration
statements  of the  Company  on Form S-3  (File  Nos.  33-62259  and  333-_____)
(collectively,  the  "Registration  Statement")  was  filed in  accordance  with
procedures  of  the  Securities  and  Exchange   Commission  (the  "Commission")
permitting a delayed or continuous  offering of securities pursuant thereto and,
if  appropriate,  a  post-effective  amendment  or  prospectus  supplement  that
provides  information  relating to the terms of the securities and the manner of
their  distribution.  The Debentures  have been offered by the Prospectus  dated
__________ (the  "Prospectus"),  as  supplemented  by the Prospectus  Supplement
dated  __________ (the  "Prospectus  Supplement"),  which updates or supplements
certain  information  contained  in  the  Prospectus.   The  Prospectus,  as  so
supplemented,  does  not  necessarily  contain  a  current  description  of  the
Company's  business and affairs since,  pursuant to form S-3, it incorporates by
reference certain documents filed with the Commission which contain  information
as of various dates.

                  In accordance with our understanding  with you as to the scope
of our  services  under the  circumstances  applicable  to the  offering  of the
Debentures,  we reviewed the  Registration  Statement,  the  Prospectus  and the
Prospectus Supplement, participated in the discussions with your representatives
and those of the Company, its counsel and its independent public accountants and
advised  you as to the  requirements  of the Act and the  applicable  rules  and
regulations  thereunder.  Between the date of the Prospectus  Supplement and the
date of delivery of this letter,  we  participated in further  discussions  with
your  representatives and those of the Company,  its counsel and its independent
public accountants  regarding the contents of certain portions of the Prospectus
and  the  Prospectus  Supplement  and  certain  related  matters,  and  reviewed
certificates of certain officers of the Company,  opinions addressed to you from
counsel to the Company  and letters  addressed  to you from  independent  public
accountants of the Company.

                  On the basis of the information that was reviewed by us in the
course of the performance of the services  referred to above, in our opinion (i)
the  Registration  Statement,  as of its effective date, and the Prospectus,  as
supplemented  by the  Prospectus  Supplement  as of the  date of the  Prospectus
Supplement,  complied as to form in all material  respects with the requirements
of the Act and the Trust Indenture Act of 1939, as amended,  and the respective,
applicable rules and regulations  thereunder  (except that we express no opinion
as to financial  statements and financial or statistical data contained  therein
or as to the Form T-1 filed as an Exhibit to the  Registration  Statement)  (ii)
the  summaries  of the terms of the  Indenture  (as such term is  defined in the
Prospectus)  and the Debentures  contained in the  Registration  Statement,  the
Prospectus  and  the  Prospectus  Supplement  fairly  describe  in all  material
respects the  provisions  thereof  required to be described in the  Registration
Statement.  Further,  nothing  that came to our  attention in the course of such
review  has  caused  us to  believe  that the  Registration  Statement,  on such
effective date,  contained any untrue statement of a material fact or omitted to
state any material fact  required to be stated  therein or necessary to make the
statements  therein not misleading,  or that the Prospectus,  as supplemented by
the Prospectus Supplement, as of the date of the Prospectus Supplement and as of
the date and time of delivery of this  letter,  contained  or contains an untrue
statement  of a  material  fact or  omitted  or omits to state a  material  fact
necessary in order to make the statements therein, in light of the circumstances
under which they were made, not misleading.

                  The limitations  inherent in the  independent  verification of
factual matters and the character of determinations involved in the registration
process  are such,  however,  that we do not assume any  responsibility  for the
accuracy,   completeness  or  fairness  of  the  statements   contained  in  the
Registration Statement, the Prospectus or the Prospectus Supplement. Also, we do
not  express  any  opinion  or belief as to the  financial  statements  or other
financial data contained in the  Registration  Statement,  the Prospectus or the
Prospectus   Supplement,   or  as  to  the  statement  of  the  eligibility  and
qualification  of the Trustee under the Indenture under which the Debentures are
being issued.

                  This  letter is  furnished  by us as counsel to you solely for
your benefit and may not be relied upon by, nor may copies be delivered  to, any
other person without our prior written consent.

                                                     Very truly yours,

                                                     DORSEY & WHITNEY LLP

                                                                      EXHIBIT D






          Pursuant to subsection (e) of Section 8 of the Underwriting Agreement,
Arthur Andersen LLP shall furnish a letter to the  Representative  to the effect
that:

         (1) They are independent  certified public  accountants with respect to
the  Company  within  the  meaning  of the  Securities  Act and  the  applicable
published rules and regulations thereunder;

         (2) In their opinion, the financial statements and schedules audited by
them and included or  incorporated  by reference in the Prospectus  comply as to
form in all material respects with the applicable accounting requirements of the
Securities  Act  and  the  Exchange  Act and the  related  published  rules  and
regulations thereunder;

         (3) On the basis of performing the procedures specified by the American
Institute  of Certified  Public  Accountants  for a review of interim  financial
information as described in SAS No. 71, Interim  Financial  Information,  on the
latest  available  unaudited  financial  statements  included or incorporated by
reference  in the  Registration  Statement,  a reading of the  latest  available
interim  unaudited  financial  statements  of the  Company,  the  minutes of the
meetings of the Board of  Directors,  the  Executive  Committee  thereof and the
stockholders  of the Company,  respectively,  since the close of the most recent
audited  fiscal year to a specified  date not more than five business days prior
to the  Closing  Date,  and  inquiries  of  officials  of the  Company  who have
responsibility for the respective company's financial and accounting matters (it
being  understood that the foregoing  procedures do not constitute an audit made
in accordance with generally accepted auditing standards and that they would not
necessarily  reveal matters of significance with respect to the comments made in
such letter, and, accordingly,  that Arthur Andersen LLP makes no representation
as  to  the  sufficiency  of  such  procedures  for  the  several  Underwriters'
purposes), nothing has come to their attention which caused them to believe that

                  (a)   the   unaudited   financial   statements   included   or
incorporated  by  reference  in the  Prospectus  do not comply as to form in all
material respects with the applicable accounting  requirements of the Securities
Act and  the  Exchange  Act and the  related  published  rules  and  regulations
thereunder;

                  (b) the audited and unaudited selected  financial  information
and supplemental  financial  information and ratios of earnings to fixed charges
included or incorporated by reference in the Prospectus do not comply as to form
in  all  material  respects  with  the  applicable  disclosure  requirements  of
Regulation S-K promulgated under the Securities Act;

                  (c) any  material  modifications  should  be  made  to  said 
unaudited  financial  statements  for them to be in  conformity  with  generally
accepted accounting principles;

                  (d) for the period from  ___________ to the date of the latest
available unaudited financial statements of the Company,  there was any decrease
in  operating  revenues,  operating  income or net income as  compared  with the
corresponding  period  in  the  preceding  year,  except  in all  instances  for
decreases which the Prospectus discloses have occurred or may occur or except as
set forth in such letter; and

                  (e) at a specified  date not more than _____ days prior to the
Closing Date there was any change in the capital stock or long-term  debt of the
Company,  in each case as compared with amounts shown in the most recent balance
sheet  incorporated by reference in the Prospectus,  except in all instances for
changes or decreases which the Prospectus  discloses have occurred or may occur,
for  declarations  of  dividends,  for the  repayment or redemption of long-term
debt,  for the  amortization  of premium or discount on long-term  debt, for the
redemption  or purchase of preferred  stock for sinking fund  purposes,  for any
increases in long-term debt in respect of previously  issued  pollution  control
revenue  bonds,  or for  changes  or  decreases  as set  forth  in such  letter,
identifying the same and specifying the amount thereof.

         (4) In addition to the audit  referred to in their reports  included or
incorporated  by reference in the Prospectus and the inspection of minute books,
inquiries and other limited  procedures  referred to in paragraph 3 above,  they
have carried out certain  specified  procedures,  not  constituting  an audit in
accordance with generally accepted auditing  standards,  with respect to certain
amounts,  percentages  and  financial  information  including  certain pro forma
information  specified by the Representative  which are derived from the general
accounting  records of the Company  which  appear in the  Prospectus  (excluding
documents  incorporated  by  reference),  or in Part II of, or in  exhibits  and
schedules to, the Registration  Statement  specified by the Representative or in
documents   incorporated  by  reference  in  the  Prospectus  specified  by  the
Representative  and agreed to by the Company,  and have compared certain of such
amounts,  percentages and financial  information with the accounting  records of
the Company and have found them to be in agreement.

such interest  payment date;  provided,  however,  that if and to the extent the
Company  shall  default in the  payment  of the  interest  due on such  interest
payment date,  such defaulted  interest shall be paid as provided in Section 307
of the Indenture.

                  The term "record date" as used in this Section with respect to
any  interest  payment date shall mean the _____ 15 or _____ 15, as the case may
be, next preceding the semi-annual  interest  payment date, or, if such _____ 15

                  SECTION 3. Except as otherwise  provided in this Section,  the
registered  owner of all Collateral Trust Bonds of the ___% Series shall be CEDE
& Co., as nominee of The Depository Trust Company  ("DTC").  Payment of interest

ownership of the  Collateral  Trust Bonds of the ___% Series shall be registered
in the registration books of the Company kept by the Trustee in the name of CEDE
& Co.,  as nominee of DTC.  The  Trustee  and the  Company may treat DTC (or its
nominee) as the sole and exclusive  owner of the  Collateral  Trust Bonds of the
___% Series  registered in its name for the purposes of payment of the principal
of,  premium,  if any, or interest  on such  Collateral  Trust Bonds of the ___%
Series,  giving any notice  permitted or required to be given to Holders herein,
registering  the  transfer of such  Collateral  Trust Bonds of the ___%  Series,
obtaining  any consent or other  action to be taken by Holders and for all other
purposes  whatsoever;  and neither the Trustee nor the Company shall be affected
by any notice to the  contrary.  Neither the Trustee nor the Company  shall have
any  responsibility or obligation to any DTC participant,  any Person claiming a
beneficiary  ownership  interest  in  Collateral  Trust Bonds of the ___% Series
registered  in the  name  of  CEDE  & Co.  under  or  through  DTC  or  any  DTC
participant, or any other Person which is not shown on the registration books of
the Company  kept by the Trustee as being a Holder with  respect to the accuracy
of any records maintained by DTC, CEDE & Co. or any DTC participant; the payment
by DTC or any DTC  participant to any beneficial  owner of any amount in respect
of the principal of, premium,  if any, or interest on the Collateral Trust Bonds
of the ___% Series registered in the name of CEDE & Co.; the delivery to any DTC
participant or any beneficial owner of any notice which is permitted or required
to be given to Holders  herein;  the selection by DTC or any DTC  participant of
any  Person  to  receive  payment  in the  event  of a  partial  payment  of any
Collateral Trust Bonds of the ___% Series  registered in the name of CEDE & Co.;
or any consent  given or other action  taken by DTC as Holder.  The Paying Agent
shall pay all  principal  of,  premium,  if any, and interest on any  Collateral
Trust Bonds of the ___% Series  registered in the name of CEDE & Co., only to or
upon the order of CEDE & Co., as nominee of DTC, and all such payments  shall be
valid and effective to fully  satisfy and  discharge  the Company's  obligations
with  respect  to the  principal  of,  premium,  if any,  and  interest  on such
Collateral  Trust  Bonds of the ___%  Series to the extent of the sum or sums so
paid.  Upon delivery by DTC to the Trustee of written  notice to the effect that
DTC had  determined  to  substitute  a new  nominee in place of CEDE & Co.,  and
subject to the provisions herein with respect to record dates, the words "CEDE &
Co." herein shall refer to such new nominee of DTC.

                  A  Global   Bond   shall  be   exchangeable   for   definitive
certificates  registered  in the names of persons  other than DTC or its nominee
only if (i) DTC  notifies the Company that it is unwilling or unable to continue
as a depositary for such Global Bond and no successor depositary shall have been
appointed, or if at any time DTC ceases to be a clearing agency registered under
the  Securities  Exchange  Act of 1934,  at a time when DTC is required to be so
registered to act as such  depositary,  (ii) the Company in its sole  discretion
determines  that such Global Bond shall be so  exchangeable or (iii) there shall
have  occurred  and be  continuing  an  Event of  Default  with  respect  to the
Collateral Trust Bonds of the ___% Series.  In any such event, the Trustee shall
issue,  register  the  transfer  of  and  exchange  definitive  certificates  as
requested by DTC in appropriate amounts and the Company and the Trustee shall be
obligated  to  deliver   definitive   certificates.   In  the  event  definitive
certificates  are issued to Holders other than DTC, the provisions  herein shall
apply to, among other things, the registration, transfer of and exchange of such
certificates  and the method of payment of principal  of,  premium,  if any, and
interest on such certificates. Whenever DTC requests the Company and the Trustee
to do so,  the  Trustee  and the  Company  will  cooperate  with  DTC in  taking
appropriate  action after  reasonable  notice (i) to make  available one or more
separate  certificates  evidencing the Collateral Trust Bonds of the ___% Series
registered in the name of CEDE & Co., to any DTC participant  having  Collateral
Trust  Bonds of the ___%  Series  credited to its DTC account or (ii) to arrange
for another bonds depository to maintain custody of certificates evidencing such
Collateral Trust Bonds of the ___% Series.

                  So long as any  Collateral  Trust Bonds of the ___% Series are
registered  in the name of CEDE & Co.,  as nominee  of DTC,  all  payments  with
respect to the principal of,  premium,  if any, and interest on such  Collateral
Trust Bonds of the ___% Series and all notices,  with respect to such Collateral
Trust Bonds of the ___% Series shall be made and given to DTC as provided in the
Letter of Representations dated __________.

                  In  connection  with any notice or other  communication  to be
provided to Holders by the Company or the Trustee with respect to any consent or
other action to be taken by Holders,  so long as any  Collateral  Trust Bonds of
the ___% Series are registered in the name of CEDE & Co., as nominee of DTC, the
Company or the Trustee,  as the case may be,  shall  establish a record date for
such  consent or other  action and give DTC notice of such  record date not less
than 15 calendar days in advance of such record date to the extent possible.

                  The   notice   requirements   set  forth  in  the   Letter  of
Representations  with respect to redemptions,  conversions and mandatory tenders
shall be effective  whenever the  Collateral  Trust Bonds of the ___% Series are
registered  in  the  name  of  DTC or its  nominee,  notwithstanding  any  other
provision  herein, to the extent such other provisions are incompatible with the
notice requirements set forth in the Letter of Representations.

                  SECTION 4. The  Collateral  Trust Bonds of the ___% Series and
the  Trustee's  Certificate  of  Authentication  shall be  substantially  in the
following forms respectively:


                             [FORM OF FACE OF BOND]

                        [FORM OF LEGEND FOR GLOBAL BOND]

Unless this  certificate  is presented by an  authorized  representative  of The
Depository Trust Company, a New York corporation ("DTC"), to Issuer or its agent
for registration of transfer, exchange or payment, and any certificate issued is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized  representative  of DTC (and any  payment is made to Cede & Co. or to
such other entity as is requested by an authorized  representative  of DTC), ANY
TRANSFER,  PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON
IS WRONGFUL inasmuch as the registered owner hereof, Cede & Co., has an interest
herein.

this  __________   Supplemental   Indenture  have  been  in  all  respects  duly
authorized.

privileges,  licenses  and  franchises  and all other  appurtenances  whatsoever
belonging or in any wise appertaining to any of the property hereby mortgaged or
pledged,  or  intended  so to be,  or any part  thereof,  now owned or which may
hereafter be owned or acquired by the Company, and the reversion and reversions,
remainder and remainders,  and the tolls,  rents,  revenues,  issues,  earnings,

estates, rights, franchises,  privileges and appurtenances mortgaged,  conveyed,
pledged or assigned as  aforesaid,  or intended so to be,  together with all the
appurtenances  thereunto  appertaining,  unto the Trustee and its successors and
assigns forever,  upon the trusts, for the uses and purposes and under the terms

set forth;

and restrictions contained in the several deeds, leases,  servitudes,  contracts
or other  instruments  through which the Company acquired and/or claims title to

the  Original  Indenture,   as  amended,   and  Section  7  of  this  __________
Supplemental Indenture;

                  BUT IN TRUST,  NEVERTHELESS,  for the equal and  proportionate
use, benefit,  security and protection of those who from time to time shall hold
the first  mortgage  bonds and coupons  authenticated  and  delivered  under the

or priority of any one first mortgage bond or coupon over any other by reason of

provisions, each and all of said first mortgage bonds and coupons shall have the
same right,  lien and  privilege  under the  Indenture  and shall be equally and
ratably  secured  thereby  (except as any  sinking,  amortization,  improvement,
renewal or other fund,  or any other  covenants  or  agreements  established  in
accordance with the provisions of the Original Indenture,  may afford additional
security for the first mortgage bonds of any particular series),  and shall have

Original Indenture),  with the same effect as if all of the first mortgage bonds
and coupons had been issued,  sold and negotiated  simultaneously on the date of

the principal of the first  mortgage  bonds and of the interest and premium,  if
any, thereon,  according to the tenor,  purport and effect of the first mortgage
bonds and coupons and of the Indenture, and for enforcing the terms, provisions,
covenants and  stipulations  therein and in the first  mortgage bonds set forth,
and upon the trusts, uses and purposes and subject to the covenants,  agreements
and conditions set forth and declared in the Indenture;

                  AND THIS __________ SUPPLEMENTAL INDENTURE FURTHER WITNESSETH,
that the  Company  hereby  covenants  and agrees to and with the Trustee and its
successors and assigns forever as follows:

                  SECTION 1. There shall be, and is hereby created, a new series
of first mortgage bonds, known as and entitled "First Mortgage Bonds, Collateral
Series __, Due ____," and the form thereof shall be substantially as hereinafter
set forth.

                  The Bonds of Series __ shall be issued  and  delivered  to the
New Mortgage Trustee under the New Mortgage as the basis for the  authentication
and delivery under the New Mortgage of a series of securities ("Collateral Trust
Securities").  As provided in the New  Mortgage,  the Bonds of Series __ will be
registered in the name of the New Mortgage Trustee, subject to the provisions of
the New Mortgage,  for the benefit of the holders of all securities from time to
time outstanding under the New Mortgage,  and the Company shall have no interest
therein.  The Bonds of Series __ will not be transferable  except to a successor
trustee under the New Mortgage.

                  Any  payment or deemed  payment by the  Company  under the New
Mortgage  of the  principal  of or  interest,  if any, on the  Collateral  Trust
Securities  (other  than by the  application  of the  proceeds  of a payment  in
respect of the Bonds of Series __) shall,  to the extent  thereof,  be deemed to
satisfy and discharge the  obligation of the Company,  if any, to make a payment
of principal of or interest, if any, on such Bonds of Series __, as the case may
be, which is then due.

                  The  principal  amount  of the  Bonds  of  Series  __ shall be
limited to  $__________,  except in case of the issuance of Bonds as provided in
Section 14 of the Original  Indenture on account of mutilated,  lost, stolen, or
destroyed  Bonds.  The Bonds of Series __ shall be registered bonds only without
coupons of the  denomination  of $1,000 and any multiple of $1,000,  and of such
respective  amounts  of each of said  denominations  as may be  executed  by the
Company  and  delivered  to  the  Trustee  for   authentication   and  delivery.
Notwithstanding  the  provisions  of Section 7 of the Original  Indenture to the
contrary, no reservation of unissued coupon bonds shall be required with respect
to the Bonds of Series __. All Bonds of Series __ shall mature  __________,  and
shall not bear interest, except that if the Company should default in payment of
principal  on a Bond of  Series  __,  such  Bond  shall  bear  interest  on such
defaulted  principal  at the rate of 6% per annum (to the extent that payment of
such  interest  is  enforceable   under  applicable  law)  until  the  Company's
obligation  with respect to the payment of such  principal  shall be discharged.
The principal, premium, if any, and the interest, if any, on the Bonds of Series
__ shall be payable at the office of the Trustee in the City of  Chicago,  State
of Illinois,  or at the option of the holder,  at the principal  corporate trust
office of First Chicago Trust Company of New York in the Borough of Manhattan in
the City of New York,  in any coin or currency  of the United  States of America
which at the time of payment shall be legal tender for public and private debts.
The  Bonds  of  Series  __  shall  be  subject  to   redemption   under  certain
circumstances specified in Section 54 of the Original Indenture as amended.

         The  Bonds  of  Series  __ will be  redeemable,  at the  option  of the
Company, in whole at any time or in part from time to time, upon 30 days notice,
at a redemption  price equal to 100% of the principal  amount  thereof  together
with accrued  interest,  if any,  thereon to the date fixed for redemption.  The
Bonds shall be redeemed no later than the  redemption  of the  Collateral  Trust
Securities,  in a principal  amount equal to the principal  amount of Collateral
Trust  Securities  then being redeemed,  and at a redemption  price equal to the
redemption price (excluding interest other than interest on defaulted principal,
if any) applicable to such redemption of Collateral Trust Securities.

                  Notwithstanding  Section  11 of the  Original  Indenture,  the
Company may execute, and the Trustee shall authenticate and deliver,  definitive
Bonds of Series __ in typewritten form.

                  Subject  to  the  provisions  of  Section  8 of  the  Original
Indenture,  all definitive Bonds of Series __ shall be interchangeable for other
Bonds of Series __ of a different authorized  denomination or denominations,  as
requested by the holder  surrendering  the same, upon surrender to the agency of
the Company in the City of Chicago,  Illinois,  or, at the option of the holder,
at the agency of the  Company  in the City of New York.  Anything  contained  in
Section 13 of the Original Indenture  notwithstanding,  upon such interchange of
Bonds of Series __, no charge may be made by the Company except the payment of a
sum sufficient to reimburse the Company for any stamp tax or other  governmental
charge incident thereto.

                  The  Trustee  is hereby  appointed  Registrar  of the Bonds of
Series __ for the purpose of registering and transferring  Bonds of Series __ as
in Section 12 of the Original Indenture provided. Bonds of Series __ may also be
so registered and  transferred at the principal  corporate trust office of First
Chicago Trust Company of New York in the Borough of Manhattan in the City of New
York,  which  company is hereby  authorized to act as  co-Registrar  of Bonds of
Series  __ in the City of New  York.  In case any  Bonds of  Series  __ shall be
redeemed  in part only,  any  delivery  pursuant  to Section 97 of the  Original
Indenture of a new Bond or Bonds of Series __ of an aggregate  principal  amount
equal to the unredeemed  portion of such Bond of Series __ shall,  at the option
of the  registered  owner,  be made by the  co-Registrar.  For all  purposes  of
Articles  Eleven and Eighteen of the Original  Indenture,  First  Chicago  Trust
Company of New York in the City of New York,  as the New York  Paying  Agent for
Bonds of Series  __,  shall be deemed  to be the  agent of the  Trustee  for the
purpose of receiving all or any part, as may be directed by the Trustee,  of any
deposit for the purpose of  redeeming,  or of paying at  maturity,  any Bonds of
Series __, and any money so deposited  with First  Chicago  Trust Company of New
York in the City of New York,  upon the  direction of the Trustee,  in trust for
the purpose of paying the  redemption  price of, or of paying at  maturity,  any
Bonds of Series __, shall be deemed to  constitute a deposit in trust with,  and
to be held in trust by, the Trustee in accordance with the provisions of Article
Eleven or Eighteen of the Original Indenture.

                  So long as any  Bonds of Series  __ shall be  outstanding,  in
addition to the offices or agencies  required to be maintained by the provisions
of the  Original  Indenture,  the  Company  shall keep or cause to be kept at an
office or agency to be  maintained  by the Company in the Borough of  Manhattan,
the City of New York,  books for the registration and transfer of Bonds pursuant
to the  foregoing  provisions  of  this  Section  and to the  provisions  of the
Original Indenture.

                  SECTION  2.  For  the  purpose  of  redemption  under  certain
circumstances  specified in Section 54 of the Original Indenture, as amended, by
the  application  of cash received by the Trustee as the result of the taking by
eminent  domain or of the purchase by a public  authority of  properties  of the
Company,  the Bonds shall be redeemable at a special redemption price of 100% of
the principal amount thereof together with accrued interest, if any, to the date
fixed for redemption.

                  SECTION 3. The Bonds and the certificate of  authentication to
be  borne  by  such  Bonds  shall  be  substantially  in  the  following  forms,

                                    Due ____

                  This  Bond  is one of an  authorized  issue  of  Bonds  of the
Company known as its "first mortgage  bonds",  issued and to be issued in series
under, and all equally and ratably secured (except as any sinking, amortization,
improvement,  renewal  or other  fund,  or any other  covenants  or  agreements,
established  in accordance  with the  provisions  of the  Indenture  hereinafter
mentioned,  may afford  additional  security for the first mortgage bonds of any
particular  series) by an  Indenture  of Mortgage  and Deed of Trust dated as of
August 1, 1940,  executed by the Company to The First  National Bank of Chicago,
as Trustee,  as supplemented by ________  Supplemental  Indentures  (including a
Seventh  Supplemental  Indenture  dated  as of July  1,  1946,  a  Thirty-second
Supplemental Indenture dated as of September 1, 1966, a Forty-fifth Supplemental
Indenture  dated as of November 1, 1976, a  Fifty-fifth  Supplemental  Indenture

Sixty-second Supplemental Indenture dated as of September 1, 1996, a Sixty-third
Supplemental Indenture dated as of April 1, 1997, and a __________  Supplemental
Indenture  dated as of  ________)  each duly  executed  by the  Company  to said
Trustee (said Indenture, as so supplemented,  being herein sometimes referred to
as the "Indenture"),  to which Indenture and all indentures supplemental thereto
reference  is hereby made for a  description  of the  properties  mortgaged  and
pledged,  the nature and extent of the  security,  the rights of the  holders of
said first mortgage  bonds,  and of the Trustee and of the Company in respect of
such security, and the terms and conditions upon which said first mortgage bonds
are  and are to be  issued  and  secured.  As  provided  in,  and to the  extent
permitted by, the  Indenture,  the rights and  obligations of the Company and of
the holders of said first  mortgage  bonds may be changed and modified  with the
consent of the Company by the affirmative vote of the holders of at least 75% in
principal amount of the first mortgage bonds then  outstanding  affected by such
change or modification  (excluding first mortgage bonds disqualified from voting
by reason of the  Company's  interest  therein as  provided  in the  Indenture);
provided,  however,  that without the consent of the registered  owner hereof no
such change or  modification  shall permit the reduction of the principal or the
extension of the maturity of the  principal of this Bond or the reduction of the
rate of  interest,  if any,  hereon  or any other  modification  of the terms of
payment of such principal or interest. As provided in the Indenture,  said first
mortgage  bonds  are  issuable  in  series  which  may vary as in the  Indenture
provided  or  permitted.  This Bond is one of a series of first  mortgage  bonds
entitled "First Mortgage Bonds, Collateral Series __, Due ____".

                  Any payment or deemed  payment by the Company of the principal
of or interest,  if any, on the Collateral  Trust  Securities (as defined in the
________ Supplemental  Indenture) (other than by the application of the proceeds
of a payment in respect of this Bond) shall, to the extent thereof, be deemed to
satisfy and discharge the  obligation of the Company,  if any, to make a payment
of principal of or interest, if any, on this Bond which is then due.

                  This Bond is  redeemable,  at the  option of the  Company,  in
whole  at any  time or in part  from  time to time,  upon 30 days  notice,  at a
redemption  price equal to 100% of the principal  amount  thereof  together with
accrued interest, if any, thereon to the date fixed for redemption. This Bond is
also subject to redemption under certain  circumstances  specified in Section 54
of the  Indenture  by the  application  of cash  received  by the Trustee as the
result of the taking by eminent domain or of the purchase by a public  authority
of  properties  of the  Company,  as more fully  provided in, and subject to the
provisions  of,  the  Indenture,  upon at least 30 days  prior  notice  given as
aforesaid,  at a  special  redemption  price  of  100% of the  principal  amount
thereof.  In addition,  the Bonds shall be redeemed by the Company no later than
the redemption of the Collateral Trust Securities in a principal amount equal to
the principal amount of Collateral Trust Securities then being redeemed,  and at
a redemption price equal to the redemption price (excluding  interest other than
interest on  defaulted  principal,  if any)  applicable  to such  redemption  of
Collateral Trust Securities.

                  If an event of  default,  as defined in the  Indenture,  shall
occur, the principal of this Bond may become or be declared due and payable,  in
the manner and with the effect provided in the Indenture.

                  To the  extent  permitted  on the front  hereof,  this Bond is
transferable by the registered owner hereof in person or by attorney  authorized
in writing at the agency of the Company in the City of Chicago, Illinois, or, at
the option of the holder,  at the agency of the Company in the City of New York,
upon  surrender and  cancellation  of this Bond and upon any such transfer a new
first mortgage bond of the same series, for the same aggregate principal amount,
will be issued to the  transferee  in  exchange  herefor.  The  Company  and the
Trustee may deem and treat the person in whose name this Bond is  registered  as
the absolute  owner  hereof,  for the purpose of  receiving  payment and for all
other purposes.

                  This Bond,  alone or with other  first  mortgage  bonds of the
same  series,  may be  exchanged  upon  surrender  thereof to the Trustee at the
agency of the Company in the City of Chicago, Illinois, or, at the option of the
holder,  at the agency of the  Company in the City of New York,  for one or more
other  first  mortgage  bonds  of the  same  series  and of the  same  aggregate
principal amount but of a different  authorized  denomination or  denominations,
upon payment of a sum  sufficient  to reimburse the Company for any stamp tax or
other  governmental  charge  incident  thereto,  and  subject  to the  terms and
conditions set forth in the Indenture.

                  No recourse  shall be had for the payment of the  principal of
or interest, if any, on this Bond, or for any claim based hereon or otherwise in
respect  hereof or of the  Indenture or of any indenture  supplemental  thereto,
against any  incorporator,  stockholder,  director,  or officer,  as such, past,
present  or  future,   of  the  Company  or  of  any  predecessor  or  successor
corporation,  either  directly  or through  the  Company or any  predecessor  or
successor corporation, whether by virtue of any constitution, statute or rule of
law,  or by the  enforcement  of any  assessment  or  penalty or by any legal or
equitable  proceeding or otherwise  howsoever;  all such liability being, by the
acceptance  hereof and as a part of the  consideration  for the issuance hereof,
expressly waived and released by every  registered  owner hereof,  as more fully
provided in the  Indenture;  provided,  however,  that nothing  herein or in the
Indenture contained shall be taken to prevent recourse to and the enforcement of
the liability,  if any, of any  shareholder or any  stockholder or subscriber to
capital stock upon or in respect of shares of capital stock not fully paid up.

                               [END OF BOND FORM]

                  SECTION 4.  Anything  contained  in  Sections 97 and 98 of the
Indenture to the contrary  notwithstanding,  if less than all of the outstanding
Bonds are to be called for  redemption,  the Bonds to be redeemed in whole or in
part shall be designated  by the Trustee  (within 10 days after receipt from the
Company of notice of its  intention  to redeem  Bonds) by lot  according to such
method as the Trustee  shall deem proper in its  discretion.  For the purpose of
any drawing,  the Trustee shall assign a number for each $1,000 principal amount
of each outstanding Bond.

                  The  provisions  of  Section  97 of the Indenture  relating to
notations of partial redemption shall not apply to the Bonds.

                  SECTION  5.  The  recitals   contained  in  this  Supplemental
Indenture  are  made  by the  Company  and  not by the  Trustee;  and all of the
provisions contained in the Original Indenture, as heretofore  supplemented,  in
respect of the rights, privileges, immunities, powers, and duties of the Trustee
shall, except as hereinabove  modified, be applicable in respect hereof as fully
and with like effect as if set forth herein in full.

                  SECTION  6.  All the  covenants,  stipulations,  promises  and
agreements  in this  Supplemental  Indenture  contained,  by or on behalf of the
Company,  shall bind and inure to the  benefit of its  successors  and  assigns,
whether so expressed or not.

                  SECTION 7. Nothing in this Supplemental Indenture expressed or
implied is intended or shall be  construed  to give to any person other than the
Company,  the Trustee,  and the holders of the first mortgage bonds any legal or
equitable  right,  remedy or claim under or in respect of the  Indenture  or any
covenant,  condition  or  provision  therein  or in  the  first  mortgage  bonds
contained, and all such covenants,  conditions,  and provisions are and shall be
held to be for the sole and  exclusive  benefit of the Company,  the Trustee and
the holders of the first mortgage bonds issued under the Indenture.

                  SECTION 8. All  references  in the  Original  Indenture to the
various  Sections and Articles thereof shall be deemed to refer to said Sections
and Articles as heretofore  amended,  and the Original Indenture shall hereafter
be construed and applied as heretofore amended and supplemented.

                  SECTION 9. This Supplemental  Indenture may be executed in any
number of counterparts,  and each of such counterparts shall for all purposes be
deemed to be an original,  and all such counterparts,  or as many of them as the
Company and the Trustee shall preserve  undestroyed,  shall together  constitute
but one and the same instrument.

                  the power and  authority to issue debt  securities,  including
                  collateral trust bonds.

         2.       The debt securities will be valid, legally binding obligations
                  of the Company.
