Ladies and Gentlemen:


      Interstate  Power and Light Company,  an Iowa  corporation  (the
"Company"),  confirms its agreement with Lehman Brothers Inc. ("Lehman
Brothers") and Merrill Lynch & Co. and Merrill Lynch,  Pierce,  Fenner
&   Smith   Incorporated   ("Merrill   Lynch")   (collectively,    the
"Underwriters",   which  term  shall  also  include  any   underwriter
substituted  as  hereinafter  provided  in  Section 10  hereof),  with
respect to the issue and sale by the Company  and the  purchase by the
Underwriters,  acting  severally  and not jointly,  of the  respective
principal  amounts  set forth on Schedule A of  $25,000,000  aggregate
principal  amount of the Company's  6.30% Senior  Debentures  due 2034
(the  "Securities").  The  Securities  will be issued  pursuant  to an
indenture  dated as of August 20, 2003 (the  "Indenture")  between the
Company  and J.P.  Morgan  Trust  Company,  National  Association,  as
successor   in   interest   to  Bank  One  Trust   Company,   National
Association,  as trustee (the  "Trustee").  The Company has previously
issued  $100,000,000  aggregate  principal  amount of its 6.30% Senior
Debentures  due 2034 under the Indenture  (the "May Notes").  The term
"Indenture,"  as used herein,  includes the Officer's  Certificate (as
defined  in  the  Indenture)  dated  as of  May 3,  2004  executed  in
connection  with the  offering  of the May Notes  (the "May  Officer's
Certificate"),  establishing  the  form  and  terms  of the May  Notes
pursuant  to  Section  301  of  the   Indenture,   and  the  Officer's
Certificate  to be executed  in  connection  with the  offering of the
Securities,  which will be of the same  series as the May  Notes.  The
Securities  are to be issued in book-entry  form and will be issued to
Cede  & Co.  as  nominee  of  The  Depository  Trust  Company  ("DTC")
pursuant to the blanket letter  agreement,  dated October 1, 2003 (the
"DTC Agreement"), between the Company and DTC.

      The Company understands that the Underwriters  propose to make a
public  offering  of the  Securities  as soon as they  deem  advisable
after this Agreement has been executed and delivered.





      The  Company  has  filed  with  the   Securities   and  Exchange
Commission  (the  "Commission")  a registration  statement on Form S-3
(No.  333-114065),  for the  registration of the Securities  under the
Securities  Act of 1933,  as amended (the "1933 Act") and the offering
thereof  from  time to time in  accordance  with Rule 415 of the rules
and  regulations of the  Commission  under the 1933 Act (the "1933 Act
Regulations").   Such   registration   statement   has  been  declared
effective  by  the   Commission,   and  the  Company  has  filed  such
post-effective  amendments thereto (or such preliminary  prospectus or
preliminary  supplemental  prospectus)  as may be  required  under the
1933 Act and the 1933 Act  Regulations,  and each such  post-effective
amendment  has  been  declared  effective  by  the  Commission.   Such
registration  statement  is  referred  to herein as the  "Registration
Statement;"  and  the  final   prospectus  and  the  final  prospectus
supplement  relating to the offering of the  Securities,  in the forms
first   furnished  to  Merrill   Lynch  by  the  Company  for  use  in
connection  with the  offering  of the  Securities,  are  collectively
referred to herein as the "Prospectus;"  provided,  however,  that all
references  to  the  "Registration  Statement"  and  the  "Prospectus"
shall also be deemed to include  all  documents  incorporated  therein
by  reference  pursuant to the  Securities  Exchange  Act of 1934,  as
amended  (the  "1934  Act"),  filed  prior  to  the  applicable  date;
provided,   further,   that  if  the  Company  files  a   registration
statement  with the  Commission  pursuant  to Rule  462(b) of the 1933
Act Regulations (the "Rule 462(b) Registration  Statement"),  then all
references  to  "Registration  Statement"  shall  also  be  deemed  to
include  the  Rule  462(b)  Registration   Statement.  A  "preliminary
prospectus"  shall  be  deemed  to refer  to (i) any  prospectus  used
before  the  Registration  Statement  became  effective  and  (ii) any
prospectus or prospectus  supplement  that omitted the  information to
be  included  upon  pricing  in a form  of  prospectus  or  prospectus
supplement  filed with the  Commission  pursuant to Rule 424(b) of the
1933 Act Regulations and was used after such  effectiveness  and prior
to the initial  delivery  of the  Prospectus  to Merrill  Lynch by the
Company.  For  purposes  of  this  Agreement,  all  references  to the
Registration  Statement,  Prospectus or  preliminary  prospectus or to
any amendment or  supplement  to any of the foregoing  shall be deemed
to  include  any  copy  filed  with  the  Commission  pursuant  to its
Electronic Data Gathering, Analysis and Retrieval system ("EDGAR").

      All  references in this  Agreement to financial  statements  and
schedules and other information  which are "contained,"  "included" or
"stated"  (or other  references  of like  import) in the  Registration
Statement,  Prospectus or  preliminary  prospectus  shall be deemed to
mean and include  all such  financial  statements  and  schedules  and
other  information  which are  incorporated  by reference,  as of such
applicable  date,  in  the  Registration   Statement,   Prospectus  or
preliminary  prospectus,  as the case may be;  and all  references  in
this   Agreement  to  the   Registration   Agreement,   amendments  or
supplements to the Registration  Statement,  Prospectus or preliminary
prospectus  shall be  deemed to  include  the  filing of any  document
under the  Securities  Exchange  Act of 1934,  as  amended  (the "1934
Act") which is incorporated by reference,  as of such applicable date,
in the Registration  Statement,  Prospectus or preliminary prospectus,
as the case may be.


      SECTION 1. Representations and Warranties.
                 ------------------------------

(a)   Representations  and  Warranties  by the  Company.  The  Company
      -------------------------------------------------
      represents  and  warrants  to each  Underwriter  as of the  date
      hereof and as of the Closing  Time  referred to in Section  2(b)
      hereof, and agrees with each Underwriter, as follows:





           (i)  Compliance   with   Registration   Requirements.   The
                -----------------------------------------------
      Company  meets  the  requirements  for use of Form S-3 under the
      1933  Act.  Each of the  Registration  Statement  and  any  Rule
      462(b)  Registration  Statement has become  effective  under the
      1933 Act and no stop order  suspending the  effectiveness of the
      Registration   Statement   or  any  Rule   462(b)   Registration
      Statement has been issued under the 1933 Act and no  proceedings
      for that purpose have been  instituted or are pending or, to the
      knowledge of the Company,  are  contemplated  by the Commission,
      and any  request on the part of the  Commission  for  additional
      information has been complied with.

           At the respective  times the  Registration  Statement,  any
      Rule  462(b)  Registration   Statement  and  any  post-effective
      amendments  thereto  became  effective  and at the Closing Time,
      the  Registration   Statement,   the  Rule  462(b)  Registration
      Statement and any amendments and  supplements  thereto  complied
      or will  comply,  as the case may be, in all  material  respects
      with  the  requirements  of  the  1933  Act  and  the  1933  Act
      Regulations  and the Trust  Indenture  Act of 1939,  as  amended
      (the  "1939  Act")  and  the  rules  and   regulations   of  the
      Commission under the 1939 Act (the "1939 Act Regulations"),  and
      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  and the Indenture  complied
      and will comply in all material  respects with the  requirements
      of the 1939 Act.  Neither the  Prospectus  nor any amendments or
      supplements  thereto,  at the  time the  Prospectus  or any such
      amendment  or  supplement  was issued and at the  Closing  Time,
      included or will include an untrue  statement of a material fact
      or omitted or will omit 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.  The
      representations  and  warranties  in this  subsection  shall not
      apply  to  statements  in or  omissions  from  the  Registration
      Statement or Prospectus  made in reliance upon and in conformity
      with  information  furnished  to the  Company  in writing by any
      Underwriter expressly for use in the Registration  Statement (or
      any amendment thereto) or Prospectus (or any amendment thereto).

           Each  preliminary  prospectus and the  prospectus  filed as
      part of the  Registration  Statement as  originally  filed or as
      part of any  amendment  thereto,  or filed  pursuant to Rule 424
      under  the 1933  Act,  complied  when so  filed in all  material
      respects  with  the 1933 Act  Regulations  and each  preliminary
      prospectus and the Prospectus  delivered to the Underwriters for
      use in  connection  with  this  offering  was  identical  to the
      electronically   transmitted   copies  thereof  filed  with  the
      Commission  pursuant to EDGAR, except to the extent permitted by
      Regulation S-T.

           (ii) Incorporated Documents.
                ----------------------

                (1)  The  documents   incorporated  or  deemed  to  be
           incorporated  by  reference in the  Registration  Statement
           and the Prospectus,  at the time they were or hereafter are
           filed with the Commission,  complied or will comply, as the
           case   may  be,   in  all   material   respects   with  the
           requirements  of the 1934 Act and the rules and regulations
           of the Commission  thereunder (the "1934 Act Regulations"),




           as  applicable,  and,  when  read  together  with the other
           information   in   the   Prospectus,   at  the   time   the
           Registration  Statement became  effective,  at the time the
           Prospectus  was issued and at the Closing Time,  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.

                (2)  The  description  of regulatory  matters to which
           the  Company is  subject,  as  disclosed  in the  Company's
           filings  with  the  Commission  under  the 1934 Act and the
           1934 Act  Regulations and as incorporated by reference into
           the  Registration  Statement,  is true and  correct  in all
           material  respects,  except to the extent such  description
           in any  specific  filing  has been  superseded,  updated or
           supplemented  by such  description  in a subsequent  filing
           under the 1934 Act or the 1934 Act  Regulations  made prior
           to  the  date  hereof  or  by  such   description   in  the
           Prospectus.

           (iii)  Independent    Accountants.    The   accountants   who
                  --------------------------
      certified  the financial  statements  and  supporting  schedules
      included in the  Registration  Statement are independent  public
      accountants  with  respect to the Company  and its  subsidiaries
      within the meaning of Regulation S-X under the 1933 Act.

           (iv) Financial   Statements.   The   financial   statements
                ----------------------
      included  in the  Registration  Statement  and  the  Prospectus,
      together with the related  schedules and notes,  present  fairly
      in all material  respects the financial  position of the Company
      and its  consolidated  subsidiaries  at the dates  indicated and
      the  statement  of  income,  changes  in common  equity and cash
      flows of the Company and its  consolidated  subsidiaries for the
      periods specified;  said financial statements have been prepared
      in conformity  with  generally  accepted  accounting  principles
      ("GAAP")  applied on a consistent  basis  throughout the periods
      involved.  The  supporting  schedules,  if any,  included in the
      Registration  Statement  present fairly in all material respects
      in accordance  with GAAP the  information  required to be stated
      therein.  The selected  financial data and the summary financial
      information  included in the  Prospectus  present  fairly in all
      material  respects the  information  shown therein and have been
      compiled  on  a  basis  consistent  with  that  of  the  audited
      financial statements included in the Registration Statement.

           (v)  No  Material  Adverse  Change in  Business.  Since the
                ------------------------------------------
      respective  dates  as of  which  information  is  given  in  the
      Registration  Statement and the Prospectus,  except as otherwise
      stated  therein,  (A) there has been no material  adverse change
      in the  condition,  financial or  otherwise,  in the earnings or
      business affairs of the Company and its subsidiaries  considered
      as one  enterprise,  whether  or  not  arising  in the  ordinary
      course  of  business   nor  has  there  been  any   developments
      involving a prospective  material  adverse change of the Company
      and its  subsidiaries  considered as one enterprise,  whether or
      not arising in the  ordinary  course of  business  (a  "Material
      Adverse  Effect"),  (B) there have been no transactions  entered
      into  by the  Company  or any of its  subsidiaries,  other  than
      those in the  ordinary  course of  business,  which are material
      with   respect  to  the  Company  and  its   subsidiaries,   and
      (C) except for regular  dividends on the common stock, par value
      $2.50 per share, of the Company,  the 8.375% Series B Cumulative
      Preferred  Stock,  $0.01 par value per share, of the Company and
      the 7.10% Series C  Cumulative  Preferred Stock, $0.01 par value
      per  share,  of the  Company  in  amounts  per  share  that  are
      consistent with past practice,  the terms of the 8.375% Series B
      Cumulative  Preferred  Stock or the terms of the 7.10%  Series C
      Cumulative  Preferred  Stock, as the case may be, there has been
      no dividend or distribution  of any kind declared,  paid or made
      by the Company on any class of its capital stock.





           (vi) Good  Standing  of the  Company.  The Company has been
                -------------------------------
      duly  organized and is validly  existing as a corporation  under
      the  laws of the  State  of Iowa  and has  corporate  power  and
      authority  to own,  lease  and  operate  its  properties  and to
      conduct  its  business as  described  in the  Prospectus  and to
      enter into and perform  its  obligations  under this  Agreement;
      and the Company is duly  qualified as a foreign  corporation  to
      transact  business  and  is  in  good  standing  in  each  other
      jurisdiction in which such  qualification  is required,  whether
      by  reason  of the  ownership  or  leasing  of  property  or the
      conduct of  business,  except where the failure so to qualify or
      to be in good  standing  would not result in a Material  Adverse
      Effect.

           (vii)  No  Significant  Subsidiaries.   The  Company  has  no
                  -----------------------------
      "significant    subsidiary"   as   defined   in   Rule 1-02   of
      Regulation S-X.

           (viii)  Capitalization.   The   authorized,   issued  and
                   --------------
      outstanding  capital  stock of the Company as of the date hereof
      is set forth in the Prospectus in the column  entitled  "Actual"
      under  the  caption   "Capitalization"  (except  for  subsequent
      issuances,  if any,  pursuant  to this  Agreement,  pursuant  to
      existing reservations,  agreements or employee benefit plans, or
      pursuant to the exercise of  convertible  securities  or options
      outstanding  on the date  hereof  or  pursuant  to any  dividend
      reinvestment  plan).  All of the issued and  outstanding  shares
      of capital  stock of the Company have been duly  authorized  and
      validly  issued and are fully paid and  non-assessable  and none
      of the  outstanding  shares of capital  stock of the Company was
      issued in violation of the  preemptive or other  similar  rights
      of any  securityholder  of the  Company.  As of the date hereof,
      except for  6,000,000  shares of the  Company's  8.375% Series B
      Cumulative   Preferred   Stock  and  1,600,000   shares  of  the
      Company's 7.10% Series C Cumulative  Preferred Stock, all of the
      issued  and  outstanding  shares  of the  capital  stock  of the
      Company  are owned by Alliant  Energy  Corporation,  a Wisconsin
      corporation  (the  "Parent"),  free  and  clear  of  all  liens,
      encumbrances,  equities  or  claims.  Immediately  prior  to the
      Closing Time,  except for 6,000,000  shares of the capital stock
      of the Company's 8.375% Series B Cumulative  Preferred Stock and
      1,600,000  shares of the  Company's  7.10%  Series C  Cumulative
      Preferred  Stock,  all of the issued and  outstanding  shares of
      capital  stock of the Company will be owned  directly by Parent,
      free and clear of all liens,  encumbrances,  equities or claims.
      The  Parent  is  a  "holding  company"  and  the  Company  is  a
      "subsidiary"  of a "holding  company"  as such terms are defined
      under  the  Public  Utility  Holding  Company  Act of  1935,  as
      amended.

           (ix)  Authorization  of  Agreement.   The  Company  has  all
                 ----------------------------
      requisite  corporate  power and authority to execute and deliver
      this Agreement and to perform its  obligations  hereunder.  This
      Agreement  has been duly  authorized,  executed and delivered by
      the Company.

           (x)  Authorization  of the  Indenture.  The  Indenture  has
                --------------------------------
      been duly authorized,  executed and delivered by the Company and
      duly  qualified  under the 1939 Act and  constitutes a valid and
      binding  agreement  of  the  Company   enforceable  against  the
      Company  in   accordance   with  its   terms,   except  (A)  the
      enforcement  thereof  may be limited by  bankruptcy,  insolvency
      (including without  limitation,  all laws relating to fraudulent
      transfers),   reorganization,   moratorium   or   similar   laws
      affecting the  enforcement  of creditors'  rights  generally and
      (B) as enforcement  thereof is subject to general  principals of
      equity  (regardless  if whether  enforcement  is considered in a
      proceeding in equity or at law).




           (xi)  Authorization  of the Securities.  The Securities have
                 --------------------------------
      been duly  authorized  and, at the Closing Time,  will have been
      duly  executed by the Company and,  when  authenticated,  issued
      and  delivered in the manner  provided for in the  Indenture and
      delivered   against  payment  of  the  purchase  price  therefor
      provided for in this Agreement,  (i) will  constitute  valid and
      binding  obligations  of the  Company,  enforceable  against the
      Company  in   accordance   with  their  terms,   except  as  the
      enforcement  thereof  may be limited by  bankruptcy,  insolvency
      (including,  without limitation, all laws relating to fraudulent
      transfers),   reorganization,   moratorium   or   similar   laws
      affecting  enforcement of creditors' rights generally and except
      as  enforcement  thereof is subject  to  general  principles  of
      equity  (regardless  of whether  enforcement  is considered in a
      proceeding  in  equity  or at  law),  (ii) will  be in the  form
      contemplated   by,  and   entitled  to  the   benefits  of,  the
      Indenture,  (iii) will constitute a "reopening" of the series of
      May Notes as  contemplated  in  numbered  paragraph 3 in the May
      Officer's  Certificate  and will have the same terms as and will
      constitute  the same  series of  Securities  (as such  terms are
      defined  in the  Indenture)  as the May Notes  for all  purposes
      under the  Indenture,  and (iv) will have the same CUSIP  number
      as, and will be fungible  and will trade  interchangeably  with,
      the May Notes.

           (xii)  Description of the  Securities and the Indenture.  The
                  ------------------------------------------------
      statements   relating  to  the   Securities  and  the  Indenture
      contained  in  the  Prospectus  conform,  respectively,  in  all
      material  respects  to the  terms  of  the  Securities  and  the
      Indenture.

           (xiii)  Absence of Defaults  and  Conflicts.  Neither the
                   -----------------------------------
      Company  nor  any of its  subsidiaries  is in  violation  of its
      charter  or  by-laws  or  in  default  in  the   performance  or
      observance of any obligation,  agreement,  covenant or condition
      contained in any contract,  indenture,  mortgage, deed of trust,
      loan or credit  agreement,  note,  lease or other  agreement  or
      instrument to which the Company or any of its  subsidiaries is a
      party or by which  it or any of them may be  bound,  or to which
      any of the  property  or  assets  of the  Company  or any of its
      subsidiaries   is   subject   (collectively,   "Agreements   and
      Instruments")  except for such violations or defaults that would
      not  result in a Material  Adverse  Effect;  and the  execution,
      delivery and  performance of this  Agreement,  the Indenture and
      the   Securities,   the   consummation   of   the   transactions
      contemplated   herein   and   in  the   Registration   Statement
      (including  the issuance and sale of the  Securities and the use
      of the proceeds from the sale of the  Securities as described in
      the  Prospectus   under  the  caption  "Use  of  Proceeds")  and
      compliance  by the Company with its  obligations  hereunder  and
      under  the   Indenture  and  the   Securities   have  been  duly
      authorized  by all  necessary  corporate  action  and do not and
      will  not,  whether  with or  without  the  giving  of notice or
      passage of time or both,  conflict  with or  constitute a breach
      of, or default or a Repayment  Event (as defined  below)  under,
      or result in the creation or imposition  of any lien,  charge or
      encumbrance  upon any  property  or assets of the Company or any
      of its subsidiaries  pursuant to, the Agreements and Instruments
      except  for such  conflicts,  breaches  or  defaults  or  liens,
      charges or encumbrances that, singly or in the aggregate,  would




      not result in a Material  Adverse  Effect,  nor will such action
      result in any violation of the provisions of (x) the  charter or
      by-laws of the  Company or any of its  subsidiaries  (except for
      such conflicts,  breaches, defaults, events or liens, charges or
      encumbrances  that  would  not  result  in  a  Material  Adverse
      Effect) or (y) any  applicable law, statute,  rule,  regulation,
      judgment,  order,  writ or decree of any government,  government
      instrumentality   or  court,   domestic   or   foreign,   having
      jurisdiction  over the Company or any of its subsidiaries or any
      of their assets,  properties or operations,  except for any such
      violations  with  respect  to  this  clause (y)  as  would  not,
      individually or in the aggregate,  result in a Material  Adverse
      Effect.  As used herein, a "Repayment  Event" means any event or
      condition  which  gives the  holder of any  note,  debenture  or
      other  evidence of  indebtedness  (or any person  acting on such
      holder's   behalf)   the  right  to  require   the   repurchase,
      redemption   or   repayment   of  all  or  a  portion   of  such
      indebtedness by the Company or any of its subsidiaries.

           (xiv)  Absence of Labor  Disputes.  No labor dispute with the
                  --------------------------
      employees of the Company or any of its  subsidiaries  exists or,
      to the  knowledge of the Company,  is imminent,  and the Company
      is not aware of any existing or imminent  labor  disturbance  by
      the  employees  of any  of  its  or  any  of  its  subsidiaries'
      respective  principal  suppliers,  manufacturers,  customers  or
      contractors,  which,  in either case, may reasonably be expected
      to result in a Material Adverse Effect.

           (xv)  Absence of  Proceedings.  Except as  disclosed  in the
                 -----------------------
      Prospectus,  there is no action,  suit,  proceeding,  inquiry or
      investigation  before or  brought  by any court or  governmental
      agency or body,  domestic or foreign,  now  pending,  or, to the
      knowledge of the Company,  threatened,  against or affecting the
      Company or any of its  subsidiaries  which might  reasonably  be
      expected to result in a Material Adverse Effect,  or which might
      reasonably  be expected to materially  and adversely  affect (A)
      the properties or assets of the Company and its  subsidiaries or
      (B) the  consummation of the  transactions  contemplated by this
      Agreement or the  performance by the Company of its  obligations
      hereunder.  The aggregate of all pending  legal or  governmental
      proceedings to which the Company or any of its  subsidiaries  is
      a party or of which any of their  respective  property or assets
      is the  subject  which  are not  described  in the  Registration
      Statement,  including ordinary routine litigation  incidental to
      the  business,  could not  reasonably be expected to result in a
      Material Adverse Effect.

           (xvi)  Accuracy  of  Exhibits.  There  are  no  contracts  or
                  ----------------------
      documents   which  are   required   to  be   described   in  the
      Registration   Statement,   the   Prospectus  or  the  documents
      incorporated  by  reference  therein or to be filed as  exhibits
      thereto  which have not been so described  and filed as required
      except  that this  Agreement  will be filed as an  exhibit  to a
      Current  Report  on  Form 8-K  which  shall  be  filed  with the
      Commission  in  accordance  with  the  1934 Act and the 1934 Act
      Regulations prior to the filing of the Prospectus.

           (xvii)  Absence  of  Further   Requirements.   No  filing
                   -----------------------------------
      with,  or  authorization,  approval,  consent,  license,  order,
      registration,   qualification   or  decree   of,  any  court  or
      governmental  authority  or agency is  necessary or required for
      the performance by the Company of its obligations hereunder,  in
      connection   with  the   offering,   issuance  or  sale  of  the
      Securities  hereunder,  the  consummation  of  the  transactions
      contemplated  by  this  Agreement  or  for  the  due  execution,




      delivery  and  performance  of the  Indenture  by  the  Company,
      except (A) such as have been already  obtained,  (B) such as may
      be required  under the 1933 Act or the 1933 Act  Regulations  or
      state  securities  laws,  and (C) such as may be required by the
      Public  Utility  Holding  Company Act of 1935,  as amended  (the
      "1935 Act"),  solely with respect to filings required to be made
      with the  Commission  subsequent  to the Closing Time (such 1935
      Act filings to be made by the Company).

           (xviii)  Possession   of   Licenses   and   Permits.   The
                    ------------------------------------------
      Company and its  subsidiaries  possess such  permits,  licenses,
      approvals,  consents  and  other  authorizations  (collectively,
      "Governmental  Licenses")  issued  by the  appropriate  federal,
      state, local or foreign regulatory  agencies or bodies necessary
      to conduct the  business  now  operated by them except where the
      failure  to possess  any such  Governmental  Licenses  would not
      have  a  Material   Adverse   Effect;   the   Company   and  its
      subsidiaries  are in compliance with the terms and conditions of
      all such Governmental  Licenses,  except where the failure so to
      possess or comply would not, singly or in the aggregate,  have a
      Material Adverse Effect;  all of the  Governmental  Licenses are
      valid and in full force and effect,  except where the invalidity
      of  such   Governmental   Licenses   or  the   failure  of  such
      Governmental  Licenses to be in full force and effect  would not
      have a Material Adverse Effect;  and neither the Company nor any
      of its  subsidiaries  has  received  any  notice of  proceedings
      relating  to  the  revocation  or   modification   of  any  such
      Governmental Licenses which, singly or in the aggregate,  if the
      subject of an  unfavorable  decision,  ruling or finding,  would
      result  in a  Material  Adverse  Effect.  Without  limiting  the
      foregoing,   the  Company  has  received  final  orders  of  the
      Illinois  Commerce  Commission,  dated  March 3,  2004,  and the
      Minnesota  Public  Utilities  Commission,  dated March 31, 2004,
      and the approval,  dated October 24, 2001,  as  supplemented  on
      June 25, 2004, of the Commission  under the 1935 Act authorizing
      the  issuance  of  the   Securities  and  such  issuance  is  in
      compliance  with the terms and  conditions  of such  orders  and
      approval.  Such  orders  and  approval  are in  full  force  and
      effect  and have  not been  amended  supplemented  or  otherwise
      modified.  No  proceeding  to review,  suspend,  limit,  modify,
      restrict  or  revoke  any  such  order  or  approval   has  been
      instituted.

           (xix)  Title to  Property.  The Company and its  subsidiaries
                  ------------------
      have good and  marketable  title to all real  property  owned by
      the  Company  and its  subsidiaries  and good title to all other
      properties  owned by them,  in each case,  free and clear of all
      mortgages,   pledges,   liens,   security   interests,   claims,
      restrictions  or encumbrances of any kind except such as (A) are
      described  in the  Prospectus  or (B) do not,  singly  or in the
      aggregate,  materially  affect the value of such property and do
      not interfere  with the use made and proposed to be made of such
      property by the Company or any of its  subsidiaries;  and all of
      the  leases  and  subleases  material  to  the  business  of the
      Company and its subsidiaries,  considered as one enterprise, and
      under  which  the  Company  or  any of  its  subsidiaries  holds
      properties  described in the  Prospectus,  are in full force and
      effect,  and neither the Company nor any of its subsidiaries has
      any  notice  of any  material  claim of any  sort  that has been
      asserted  by anyone  adverse to the rights of the Company or any
      of  its  subsidiaries  under  any  of the  leases  or  subleases
      mentioned  above,  or affecting or questioning the rights of the
      Company or any of its  subsidiaries to the continued  possession
      of the  leased or  subleased  premises  under any such  lease or
      sublease,  except  where such would not have a Material  Adverse
      Effect.




           (xx)  Investment  Company  Act. The Company is not, and upon
                 ------------------------
      the issuance and sale of the  Securities as herein  contemplated
      and the  application of the net proceeds  therefrom as described
      in the  Prospectus  will not be, an  "investment  company" or an
      entity  "controlled"  by an  "investment  company" as such terms
      are defined in the  Investment  Company Act of 1940,  as amended
      (the "1940 Act").

                  --------------------
      Registration  Statement  and except as would  not,  singly or in
      the aggregate,  result in a Material Adverse Effect, (A) neither
      the Company nor any of its  subsidiaries  is in violation of any
      federal,   state,   local  or  foreign   statute,   law,   rule,
      regulation,  ordinance,  code,  policy or rule of common  law or
      any   judicial   or   administrative   interpretation   thereof,
      including any judicial or administrative order, consent,  decree
      or  judgment,  relating  to  pollution  or  protection  of human
      health, the environment (including,  without limitation, ambient
      air,  surface  water,  groundwater,  land surface or  subsurface
      strata) or wildlife,  including,  without  limitation,  laws and
      regulations  relating  to the release or  threatened  release of
      chemicals, pollutants,  contaminants,  wastes, toxic substances,
      hazardous   substances,    petroleum   or   petroleum   products
      (collectively,  "Hazardous  Materials")  or to the  manufacture,
      processing,  distribution,  use, treatment,  storage,  disposal,
      transport  or handling  of  Hazardous  Materials  (collectively,
      "Environmental  Laws"),  (B) the  Company  and its  subsidiaries

      any  applicable  Environmental  Laws and are each in  compliance
      with their  requirements,  (C) there  are no pending  or, to the
      knowledge of the Company, threatened administrative,  regulatory

      liens,  notices of noncompliance or violation,  investigation or
      proceedings  relating  to  any  Environmental  Law  against  the
      Company or any of its  subsidiaries  and (D) there are no events
      or  circumstances  that might reasonably be expected to form the
      basis of an order for  clean-up  or  remediation,  or an action,
      suit or proceeding by any private party or governmental  body or
      agency,   against  or  affecting  the  Company  or  any  of  its
      subsidiaries    relating   to   Hazardous   Materials   or   any
      Environmental Laws.

(b)   Officer's  Certificates.  Any certificate  signed by any officer
      of the  Company  or any of  its  subsidiaries  delivered  to the
      Underwriters or to counsel for the Underwriters  shall be deemed
      a   representation   and   warranty   by  the  Company  to  each
      Underwriter as to the matters covered thereby.


      SECTION 2.  Sale and Delivery to Underwriters; Closing.
                  ------------------------------------------

(a)   The   Securities.   On  the   basis   of  the   representations,
      warranties  and agreements  herein  contained and subject to the
      terms and  conditions  herein set forth,  the Company  agrees to
      sell to each  Underwriter,  severally and not jointly,  and each
      Underwriter,  severally and not jointly, agrees to purchase from
      the  Company,  at  the  price  set  forth  in  Schedule  B,  the
      aggregate   principal   amount  of   Securities   set  forth  in
      Schedule A  opposite  the  name of such  Underwriter,  plus  any
      additional   principal   amount   of   Securities   which   such
      Underwriter  may become  obligated  to purchase  pursuant to the
      provisions of Section 10 hereof.


(b)   Payment.  Payment of the  purchase  price for,  and  delivery of
      certificates  for, the  Securities  shall be made at the offices
      of the Company at 4902 North Biltmore Lane, Madison,  Wisconsin,




      53718,  or at such  other  place as shall be agreed  upon by the
      Underwriters  and the Company,  at 10:00 A.M.  (Eastern time) on
      the third business day after the date hereof  (unless  postponed
      in accordance  with the provisions of Section 10), or such other
      time not later than ten  business  days after such date as shall
      be agreed upon by the  Underwriters  and the Company  (such time
      and  date of  payment  and  delivery  being  herein  called  the
      "Closing Time").


      Payment  shall  be  made to the  Company  by  wire  transfer  of
immediately  available  funds  to a  bank  account  designated  by the
Company,  against  delivery to the  Underwriters of  certificates  for
the  Securities  to be purchased by them.  Either  Lehman  Brothers or
Merrill  Lynch,  individually  and  not  as a  representative  of  the
other,  may  (but  shall  not be  obligated  to) make  payment  of the
purchase  price  for  all  or  a  portion  of  the  Securities  to  be
purchased  by  the  other   Underwriter  whose  funds  have  not  been
received  by the  Closing  Time,  but such  payment  shall not relieve
such other Underwriter from its obligations hereunder.

(c)   Denominations;  Registration.  Certificates  for the  Securities
      shall  be  in  such  denominations  (in  integral  multiples  of
      $1,000) as the  Underwriters may request in writing at least two

      packaging by the  Underwriters  in New York,  New York not later
      than noon  (Eastern  time) on the last business day prior to the
      Closing Time.


      SECTION 3.  Covenants  of  the  Company.  The  Company  covenants
                  ---------------------------
with each Underwriter as follows:

(a)   Compliance   with   Securities    Regulations   and   Commission
      Requests.  The  Company,  subject to Section  3(b),  will notify
      the Underwriters  immediately and confirm the notice in writing,
      (i) when  any  post-effective   amendment  to  the  Registration
      Statement  shall  become  effective,  or any  supplement  to the
      Prospectus  or any  amended  Prospectus  shall have been  filed,
      (ii) of the receipt of any  comments  from the  Commission  with
      respect to the Registration  Statement,  (iii) of any request by
      the Commission for any amendment to the  Registration  Statement
      or  any  amendment  or  supplement  to  the  Prospectus  or  for
      additional   information,   and  (iv) of  the  issuance  by  the
      Commission of any stop order  suspending  the  effectiveness  of
      the  Registration  Statement  or  of  any  order  preventing  or
      suspending  the  use of any  preliminary  prospectus,  or of the
      suspension of the  qualification  of the Securities for offering
      or  sale  in  any   jurisdiction,   or  of  the   initiation  or
      threatening of any  proceedings  for any of such  purposes.  The
      Company will promptly effect the filings  necessary  pursuant to
      Rule  424(b) and will take such steps as it deems  necessary  to
      ascertain  promptly  whether the form of prospectus  transmitted
      for filing  under Rule  424(b)  was  received  for filing by the
      Commission  and, in the event that it was not, it will  promptly
      file such  prospectus.  The Company  will make every  reasonable
      effort to prevent  the  issuance  of any stop order and,  if any
      stop  order is  issued,  to obtain  the  lifting  thereof at the
      earliest possible moment.


(b)   Filing of  Amendments.  The Company  will give the  Underwriters
      notice of its  intention to file or prepare any amendment to the
      Registration   Statement   (including   any  filing  under  Rule
      462(b)),  any  amendment,  supplement  or revision to either the





      prospectus  included in the  Registration  Statement at the time
      it became  effective or to the Prospectus,  whether  pursuant to
      the 1933  Act,  the  1934 Act or  otherwise,  will  furnish  the
      Underwriters  with  copies of any such  documents  a  reasonable
      amount of time  prior to such  proposed  filing  or use,  as the
      case may be,  and will  not  file or use any  such  document  to
      which the  Underwriters  or counsel for the  Underwriters  shall
      reasonably object.



(c)   Delivery of Registration  Statements.  The Company has furnished
      or  will  deliver  to  the  Underwriters  and  counsel  for  the
      Underwriters,  without  charge,  copies  (one of which  shall be
      manually  signed) of the  Registration  Statement as  originally
      filed and of each amendment  thereto  (including  exhibits filed
      therewith or  incorporated  by reference  therein and  documents
      incorporated or deemed to be incorporated by reference  therein)
      and  copies  (one of which  shall  be  manually  signed)  of all
      consents and  certificates of experts,  and will also deliver to

      Registration   Statement  as   originally   filed  and  of  each
      amendment   thereto   (without   exhibits)   for   each  of  the
      Underwriters.  The  copies  of the  Registration  Statement  and
      each amendment  thereto  furnished to the  Underwriters  will be
      identical  to  the  electronically  transmitted  copies  thereof
      filed  with the  Commission  pursuant  to  EDGAR,  except to the
      extent permitted by Regulation S-T.


(d)   Delivery of  Prospectuses.  The Company  has  delivered  or will
      deliver to each  Underwriter,  without charge, as many copies of
      each  preliminary   prospectus  and  final  prospectus  as  such
      Underwriter   reasonably  requested,   and  the  Company  hereby
      consents to the use of such  copies for  purposes  permitted  by
      the 1933 Act.  The  Company  will  furnish to each  Underwriter,
      without  charge,  during  the  period  when  the  Prospectus  is
      required  to be  delivered  under  the 1933 Act or the 1934 Act,
      such  number  of  copies  of  the   Prospectus  (as  amended  or
      supplemented)  as such Underwriter may reasonably  request.  The
      Prospectus and any amendments or supplements  thereto  furnished
      to the  Underwriters  will be  identical  to the  electronically
      transmitted  copies thereof filed with the  Commission  pursuant
      to EDGAR, except to the extent permitted by Regulation S-T.


(e)   Continued  Compliance  with  Securities  Laws.  The Company will
      comply  with the 1933 Act and the 1933 Act  Regulations  and the
      1934 Act and the 1934 Act  Regulations  and the 1939 Act and the
      1939 Act  Regulations  so as to  permit  the  completion  of the
      distribution   of  the  Securities  as   contemplated   in  this
      Agreement  and  in  the  Prospectus.  If  at  any  time  when  a
      prospectus  is  required  by the  1933  Act to be  delivered  in
      connection with sales of the  Securities,  any event shall occur
      or condition  shall exist as a result of which it is  necessary,
      in the  reasonable  opinion of counsel for the  Underwriters  or
      for the Company,  to amend the  Registration  Statement or amend
      or supplement the  Prospectus in order that the Prospectus  will
      not include any untrue  statements of a material fact or omit to
      state a material fact  necessary in order to make the statements
      therein  not  misleading  in  the  light  of  the  circumstances
      existing at the time it is delivered  to a  purchaser,  or if it
      shall be necessary,  in the reasonable  opinion of such counsel,




      at any such time to amend the  Registration  Statement  or amend
      or  supplement  the  Prospectus  in  order  to  comply  with the
      requirements  of the 1933 Act or the 1933 Act  Regulations,  the
      Company  will  promptly  prepare  and file with the  Commission,
      subject to Section 3(b),  such amendment or supplement as may be
      necessary to correct  such  statement or omission or to make the
      Registration  Statement  or  the  Prospectus  comply  with  such
      requirements,  and the Company will furnish to the  Underwriters
      such number of copies of such  amendment  or  supplement  as the
      Underwriters may reasonably request.


(f)   Blue  Sky   Qualifications.   The  Company  will  use  its  best
      efforts,  in cooperation with the  Underwriters,  to qualify the
      Securities   for   offering   and  sale  under  the   applicable
      securities  laws of such states and other  jurisdictions  as the
      Underwriters  may designate and to maintain such  qualifications
      in effect so long as  required  for the sale of the  Securities;
      provided,  however,  that the Company  shall not be obligated to
      file any general  consent to service of process or to qualify as
      a  foreign  corporation  or as a  dealer  in  securities  in any
      jurisdiction  in  which  it is not so  qualified  or to  subject
      itself  to  taxation  in  respect  of  doing   business  in  any
      jurisdiction  in which it is not  otherwise so subject.  In each
      jurisdiction  in which the  Securities  have been so  qualified,
      the  Company  will file such  statements  and  reports as may be
      required  by the  laws of such  jurisdiction  to  continue  such
      qualification in effect for such period.


(g)   Rule 158.  The Company  will timely file such  reports  pursuant
      to the 1934  Act as are  necessary  in  order to make  generally
      available  to its  securityholders  as  soon as  practicable  an
      earnings  statement  for the  purposes  of, and to  provide  the
      benefits  contemplated  by, the last  paragraph of Section 11(a)
      of the 1933 Act.


(h)   Use  of  Proceeds.   The  Company  will  use  the  net  proceeds

      indirectly,  offer,  pledge,  sell,  contract to sell,  sell any
      option or contract to purchase,  purchase any option or contract
      to sell,  grant any  option,  right or  warrant to  purchase  or

      exchangeable  for debt  securities  of the  Company  or file any
      registration  statement  under the 1933 Act with  respect to any
      of the  foregoing  or (ii)  enter  into  any  swap or any  other
      agreement  or any  transaction  that  transfers,  in whole or in
      part,  directly  or  indirectly,  the  economic  consequence  of
      ownership of debt  securities  of the Company,  whether any such
      swap or transaction  described in clause (i) or (ii) above is to
      be settled by  delivery  of debt  securities  of the  Company or
      such  other  securities,  in cash or  otherwise.  The  foregoing
      sentence shall not apply to the Securities to be sold hereunder.

      the  Prospectus  is required to be delivered  under the 1933 Act
      or the 1934 Act,  will file all  documents  required to be filed

      1935 Act so as to permit the completion of the  distribution and
      sale of the Securities as  contemplated in this Agreement and in
      the Prospectus.

      action  necessary to enable Standard & Poor's Ratings  Services,
      a division of McGraw Hill, Inc.  ("S&P"),  and Moody's Investors
      Service Inc.  ("Moody's")  to provide  their  respective  credit
      ratings of the Securities.

      with  the  terms  and  conditions  of the  final  orders  of the

      Company,  its  directors,  each of its  officers  who signed the
      Registration  Statement,  and each person,  if any, who controls
      the Company  within the meaning of Section 15 of the 1933 Act or
      Section 20 of the 1934 Act against any and all loss,  liability,
      claim,  damage and expense described in the indemnity  contained
      in  subsection (a) of this Section,  as incurred,  but only with
      respect to untrue  statements  or omissions,  or alleged  untrue
      statements or omissions,  made in the Registration Statement (or
      any  amendment  thereto) or any  preliminary  prospectus  or the
      Prospectus (or any amendment or supplement  thereto) in reliance
      upon and in  conformity  with written  information  furnished to
      the  Company  by  such  Underwriter  expressly  for  use  in the
      Registration  Statement  (or  any  amendment  thereto)  or  such
      preliminary  prospectus or the  Prospectus  (or any amendment or
      supplement thereto).


(c)   Actions against Parties;  Notification.  Each indemnified  party
      shall give notice as promptly as reasonably  practicable to each
      indemnifying  party  of  any  action  commenced  against  it  in
      respect of which indemnity may be sought hereunder,  but failure
      to so notify  an  indemnifying  party  shall  not  relieve  such
      indemnifying  party from any  liability  hereunder to the extent
      it is not  materially  prejudiced as a result thereof and in any
      event shall not relieve it from any liability  which it may have
      otherwise  than on account of this indemnity  agreement.  In the
      case of parties  indemnified  pursuant  to Section  6(a)  above,
      counsel to the  indemnified  parties  shall be  selected  by the
      Underwriters,  and, in the case of parties indemnified  pursuant
      to Section 6(b) above,  counsel to the indemnified parties shall
      be  selected  by  the  Company.   An   indemnifying   party  may
      participate  at its  own  expense  in the  defense  of any  such
      action;  provided,  however,  that  counsel to the  indemnifying
      party  shall not  (except  with the  consent of the  indemnified
      party)  also be counsel to the  indemnified  party.  In no event
      shall the  indemnifying  parties be liable for fees and expenses
      of more than one  counsel  (in  addition  to any local  counsel)
      separate from their own counsel for all  indemnified  parties in
      connection  with any one  action  or  separate  but  similar  or
      related  actions  in the same  jurisdiction  arising  out of the
      same general  allegations  or  circumstances.  In addition,  the
      indemnifying  party shall be entitled  to, to the extent that it
      wishes,  jointly with any other similarly notified  indemnifying
      party,  to assume  the  defense  of any claim or action  brought
      against   an   indemnified   party   with   counsel   reasonably




      satisfactory  to the  indemnified  party.  After notice from the
      indemnifying  party to the indemnified  party of its election to
      assume the  defense of such  claim or action,  the  indemnifying
      party  shall not be liable to the  indemnified  party under this
      Section 6 for any legal or other expenses  subsequently incurred
      by the indemnified  party in connection with the defense thereof
      other  than  reasonable   costs  of   investigation;   provided,
      however,  that the  Underwriters  shall have the right to employ
      one counsel (in  addition to local  counsel) to  represent  them
      and those  other  Underwriters  and their  respective  officers,
      employees  and  controlling   persons  who  may  be  subject  to
      liability   arising  out  of  any  claim  in  respect  of  which
      indemnity may be sought by the Underwriters  against the Company
      under  this  Section 6  if, in the  reasonable  judgment  of the
      Underwriters,   either  (i) there  is  an  actual  or  potential
      conflict  between  the  position  of the Company on the one hand
      and the  Underwriters  on the other  hand or  (ii) there  may be
      defenses  available  to it or them  that are  different  from or
      additional  to those  available  to the Company (in any of which
      events  the  Company  shall  not have the  right to  direct  the
      defense  of such  action  on  behalf  of the  Underwriters  with
      respect  to such  different  defenses),  in any of which  events
      such  reasonable  fees  and  expenses  shall  be  borne  by  the
      Company.   No  indemnifying  party  shall,   without  the  prior
      written   consent  of  the   indemnified   parties,   settle  or
      compromise  or consent to the entry of any judgment with respect
      to any  litigation,  or any  investigation  or proceeding by any
      governmental  agency or body,  commenced or  threatened,  or any
      claim  whatsoever  in  respect  of  which   indemnification   or
      contribution  could be sought  under this Section 6 or Section 7
      hereof  (whether  or not the  indemnified  parties are actual or
      potential parties thereto),  unless such settlement,  compromise
      or  consent  (i)  includes  an  unconditional  release  of  each
      indemnified  party  from  all  liability  arising  out  of  such
      litigation,  investigation,  proceeding  or claim and  (ii) does
      not  include  a  statement  as  to  or an  admission  of  fault,
      culpability  or a  failure  to  act  by  or  on  behalf  of  any
      indemnified party.


(d)   Settlement  without  Consent if Failure to Reimburse.  If at any
      time an indemnified  party shall have requested an  indemnifying
      party to reimburse the  indemnified  party for fees and expenses
      of  counsel,  such  indemnifying  party  agrees that it shall be
      liable for any settlement of the nature  contemplated by Section
      6(a)(ii)  effected  without  its  written  consent  if (i)  such
      settlement  is entered  into more than 45 days after  receipt by
      such  indemnifying  party of the  aforesaid  request,  (ii) such
      indemnifying  party shall have  received  notice of the terms of
      such settlement at least 30 days prior to such settlement  being
      entered  into and (iii) such  indemnifying  party shall not have
      reimbursed  such  indemnified  party  in  accordance  with  such
      request prior to the date of such settlement.




      SECTION 7.  Contribution.  If the  indemnification  provided  for
                  ------------
in Section 6  hereof is for any reason  unavailable to or insufficient
to hold  harmless  an  indemnified  party in  respect  of any  losses,
liabilities,  claims,  damages or expenses  referred to therein;  then
each  indemnifying  party shall  contribute to the aggregate amount of
such losses,  liabilities,  claims,  damages and expenses  incurred by
such  indemnified  party,  as incurred,  (i) in such  proportion as is
appropriate to reflect the relative  benefits  received by the Company
on the one  hand  and the  Underwriters  on the  other  hand  from the
offering of the  Securities  pursuant to this Agreement or (ii) if the
allocation  provided  by clause  (i) is not  permitted  by  applicable
law,  in such  proportion  as is  appropriate  to reflect not only the
relative  benefits  referred  to in  clause  (i)  above  but  also the
relative   fault  of  the   Company   on  the  one  hand  and  of  the
Underwriters  on the other hand in connection  with the  statements or
omissions,  which  resulted  in  such  losses,  liabilities,   claims,
damages  or  expenses,   as  well  as  any  other  relevant  equitable
considerations.

      The  relative  benefits  received by the Company on the one hand
and  the  Underwriters  on the  other  hand  in  connection  with  the
offering  of the  Securities  pursuant  to  this  Agreement  shall  be
deemed  to be in the same  respective  proportions  as the  total  net
proceeds  from  the  offering  of  the  Securities  pursuant  to  this
Agreement  (before  deducting  expenses)  received  by the Company and
the total  underwriting  discount  received  by the  Underwriters,  in
each  case as set forth on the  cover of the  Prospectus,  bear to the
aggregate  initial  public  offering  price of the  Securities  as set
forth on such cover.

      The  relative  fault  of the  Company  on the one  hand  and the
Underwriters  on the other hand shall be  determined  by reference to,
among  other  things,  whether  any  such  untrue  or  alleged  untrue
statement  of a  material  fact or  omission  or alleged  omission  to
state a material fact relates to  information  supplied by the Company
or by the  Underwriters and the parties'  relative intent,  knowledge,
access to  information  and  opportunity  to correct  or prevent  such
statement or omission.

      The  Company  and the  Underwriters  agree  that it would not be
just and  equitable  if  contribution  pursuant to this Section 7 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  the   equitable
considerations  referred  to above in this  Section  7. The  aggregate
amount of losses,  liabilities,  claims, damages and expenses incurred
by an  indemnified  party  and  referred  to above in this  Section  7
shall be deemed to  include  any  legal or other  expenses  reasonably
incurred by such  indemnified  party in  investigating,  preparing  or
defending  against any litigation,  or any investigation or proceeding
by any governmental  agency or body,  commenced or threatened,  or any
claim  whatsoever  based  upon  any  such  untrue  or  alleged  untrue
statement or omission or alleged omission.

      Notwithstanding   the   provisions   of  this   Section   7,  no
Underwriter  shall be required to  contribute  any amount in excess of
the  amount  by  which  the  total  price  at  which  the   Securities
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 any  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 1933  Act)  shall  be  entitled  to
contribution  from any person  who was not  guilty of such  fraudulent
misrepresentation.

      For  purposes  of this  Section  7,  each  person,  if any,  who
controls an  Underwriter  within the meaning of Section 15 of the 1933
Act or  Section  20 of the 1934 Act  shall  have  the same  rights  to
contribution  as such  Underwriter,  and each director of the Company,
each  officer of the  Company who signed the  Registration  Statement,
and each person,  if any, who controls the Company  within the meaning
of  Section  15 of the 1933 Act or  Section  20 of the 1934 Act  shall
have  the  same   rights  to   contribution   as  the   Company.   The
Underwriters'  respective  obligations to contribute  pursuant to this
Section  7 are  several  in  proportion  to the  principal  amount  of
Securities  set forth opposite  their  respective  names in Schedule A
hereto and not joint.

      SECTION 8. Representations,   Warranties   and  Agreements  to
                 ---------------------------------------------------
Survive  Delivery.  All  representations,  warranties  and  agreements
- -----------------
contained  in this  Agreement  or in  certificates  of officers of the
Company or any of its subsidiaries  submitted  pursuant hereto,  shall
remain  operative  and in full  force and  effect,  regardless  of any
investigation  made by or on behalf of any  Underwriter or controlling
person,  or by  or  on  behalf  of  the  Company,  and  shall  survive
delivery of and payment for the Securities to the Underwriters.

      SECTION 9. Termination of Agreement.
                 ------------------------

(a)   Termination;   General.  The  Underwriters  may  terminate  this
      Agreement,  by notice to the Company, at any time at or prior to
      the  Closing  Time  (i) if  there  has  been,  since the time of
      execution of this Agreement or since the respective  dates as of
      which  information is given in the Prospectus  (exclusive of any
      supplement   thereto),   any  material  adverse  change  in  the
      condition,  financial or otherwise,  in the earnings or business
      affairs of the Company and its  subsidiaries  considered  as one
      enterprise,  whether or not  arising in the  ordinary  course of
      business,  or any developments  involving a prospective material
      adverse  change of the Company and its  subsidiaries  considered
      as one  enterprise,  whether  or  not  arising  in the  ordinary
      course of  business,  or (ii) if  there has  occurred  after the
      date hereof and prior to the Closing Time any  material  adverse
      change in the  financial  markets  in the  United  States or the
      international  financial markets, any outbreak of hostilities or
      escalation  thereof or other calamity or crisis or any change or
      development  involving  a  prospective  change  in  national  or
      international  political,  financial or economic conditions,  in
      each  case the  effect  of  which is such as to make it,  in the
      reasonable  judgment  of  the  Underwriters,   impracticable  to
      market the  Securities  or to enforce  contracts for the sale of
      the  Securities,  or (iii) if  trading in any  securities of the
      Company or the Parent has been  suspended or materially  limited
      by the Commission or the New York Stock Exchange,  or if trading
      generally on the American  Stock  Exchange or the New York Stock
      Exchange or the Nasdaq  National  Market has been  suspended  or
      materially  limited,  or minimum or maximum  prices for  trading
      have  been  fixed,  or  maximum  ranges  for  prices  have  been
      required,  by any of  said  exchanges  or by such  system  or by
      order of the Commission,  the National Association of Securities
      Dealers, Inc. or any other governmental  authority, or (iv) if a
      banking  moratorium  has been declared by either  Federal or New
      York authorities.





(b)   Liabilities.  If this  Agreement is terminated  pursuant to this
      Section,  such  termination  shall be without  liability  of any
      party to any  other  party  except  as  provided  in  Section  4
      hereof,  and provided  further that Sections 1, 6, 7 and 8 shall
      survive such termination and remain in full force and effect.


      SECTION 10.    Default  by One or More of the  Underwriters.  If
                     --------------------------------------------
one of the  Underwriters  shall fail at the  Closing  Time to purchase
the   Securities   which  it  is  obligated  to  purchase  under  this
Agreement   (the   "Defaulted    Securities"),    the   non-defaulting
Underwriter  shall  have the right,  within  24 hours  thereafter,  to
make  arrangements  for it-,  or any other  underwriters,  to purchase
all,  but not less  than  all,  of the  Defaulted  Securities  in such
amounts  as may be agreed  upon and upon the terms  herein  set forth;
if, however,  the non-defaulting  Underwriter shall not have completed
such arrangements within such 24-hour period, then:


(a)   if the aggregate  principal amount of Defaulted  Securities does
      not exceed 10% of the aggregate  principal  amount of Securities
      to be purchased  on such date,  the  non-defaulting  Underwriter
      shall be obligated to purchase the full amount thereof, or


(b)   if  the  aggregate  principal  amount  of  Defaulted  Securities
      exceeds 10% of the aggregate  principal  amount of Securities to
      be  purchased  on such  date,  this  Agreement  shall  terminate
      without liability on the part of the non-defaulting Underwriter.


      No action  taken  pursuant  to this  Section  shall  relieve any
defaulting Underwriter from liability in respect of its default.

      In the  event of any such  default  which  does not  result in a
termination  of  this  Agreement,   either  the  Underwriters  or  the
Company  shall  have the  right to  postpone  the  Closing  Time for a
period  not  exceeding  seven  days in order to  effect  any  required
changes in the  Registration  Statement or  Prospectus or in any other
documents  or  arrangements.  As used herein,  the term  "Underwriter"
includes  any  person   substituted  for  an  Underwriter  under  this
Section 10.

      SECTION 11.  Notices.   All  notices   and  other   communications
                   -------

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

                              SCHEDULE B



                  INTERSTATE POWER AND LIGHT COMPANY
                        (an Iowa corporation)


                   6.30% SENIOR DEBENTURES DUE 2034

      1.   The initial public  offering price of the Securities  shall
be 100.932% of the principal  amount  thereof,  plus accrued  interest
from May 6, 2004.

      2.   The purchase price to be paid by the  Underwriters  for the
Securities  shall be 100.057% of the principal  amount  thereof,  plus
accrued interest from May 6, 2004.

      3.   The  interest  rate on the  Securities  shall be 6.30%  per
annum.

      4.   The  Company may redeem the  Securities  at any time at its
option,  in whole or in part,  at a redemption  price equal to the sum
of the  principal  amount of the  Securities  to be redeemed,  accrued
interest  on that  principal  amount  to the  redemption  date and the
make-whole  amount,  if any,  with  respect  to the  Securities  to be
redeemed. This sum is referred to as the redemption price.

      "Make-whole  amount"  means,  in  connection  with the  optional
redemption, the excess, if any, of:

      o    the aggregate  present value as of the date of any optional
           redemption of each dollar of principal  being  redeemed and
           the amount of interest,  exclusive  of interest  accrued to
           the date of  redemption,  that would  have been  payable in
           respect of such dollar of principal if such  redemption had
           not been made, determined by discounting,  on a semi-annual
           basis,  such  principal  and  interest at the  reinvestment
           rate,  as  determined  on the third  business day preceding
           the date that notice of the  redemption is given,  from the
           respective  dates  on which  such  principal  and  interest
           would  have been  payable if such  redemption  had not been
           made, over

      o    the  aggregate  principal  amount of the  Securities  being
           redeemed.

      "Reinvestment  rate" means 0.20% plus the arithmetic mean of the
yields under the headings  "Week Ending"  published in the most recent
statistical  release under the caption "Treasury Constant  Maturities"
for the maturity,  rounded to the nearest month,  corresponding to the
remaining  life to maturity,  as of the payment date of the  principal
being redeemed.  If no maturity exactly  corresponds to such maturity,
yields for the two  published  maturities  most closely  corresponding
to  such  maturity  will be  calculated  pursuant  to the  immediately
preceding  sentence and the reinvestment  rate will be interpolated or
extrapolated  from such yields on a straight-line  basis,  rounding in
each of the  relevant  periods to the nearest  month.  For purposes of
calculating  the  reinvestment   rate,  the  most  recent  statistical
release   published  prior  to  the  date  of   determination  of  the

                              EXHIBIT A



                  FORM OF OPINION OF FOLEY & LARDNER
                     TO BE DELIVERED PURSUANT TO
                             SECTION 5(b)



      The Company is validly existing as a corporation  under the laws
of the State of Iowa.

      The Company has corporate  power and authority to own, lease and
operate its  properties  and to conduct its  business as  described in
the  Prospectus  and to enter into and perform its  obligations  under
the Purchase Agreement.

      The  Company  is duly  qualified  as a  foreign  corporation  to
transact   business  and  is  in  good   standing  in  each   domestic
jurisdiction  in which  such  qualification  is  required,  whether by
reason of the  ownership  or leasing  of  property  or the  conduct of
business,  except  where the  failure  so to  qualify or to be in good
standing would not result in a Material Adverse Effect.

      The  shares  of  issued  and  outstanding  capital  stock of the
Company  have been duly  authorized  and validly  issued and are fully
paid and  non-assessable;  and, to the best of our knowledge,  none of
the  outstanding  shares of capital  stock of the Company  were issued
in  violation  of   preemptive   or  other   similar   rights  of  any
securityholder of the Company.

      The Company has no  "significant  subsidiary" as defined in Rule
1-02 of Regulation S-X.

      The Company has all requisite  corporate  power and authority to
execute  and  deliver  the  Purchase  Agreement  and  to  perform  its
obligations   thereunder.   The  Purchase   Agreement  has  been  duly
authorized, executed and delivered by the Company.

      The Indenture has been duly  authorized,  executed and delivered
by the Company and  (assuming  the due  authorization,  execution  and
delivery  thereof  by the  Trustee)  constitutes  a valid and  binding
agreement  of  the  Company,   enforceable   against  the  Company  in
accordance with its terms,  except as the  enforcement  thereof may be
limited by  bankruptcy,  insolvency  (including,  without  limitation,
all  laws   relating   to   fraudulent   transfers),   reorganization,
moratorium  or  similar  laws  affecting   enforcement  of  creditors'
rights  generally  and  except as  enforcement  thereof  is subject to
general  principles of equity  (regardless  of whether  enforcement is
considered in a proceeding in equity or at law).

      The  Securities are in the form  contemplated  by the Indenture,
have been duly  authorized  by the Company and,  when  executed by the
Company and  authenticated  by the  Trustee in the manner  provided in
the Indenture  (assuming due authorization,  execution and delivery of
the  Indenture  by the  Trustee),  and  issued and  delivered  against
payment of the  purchase  price  therefor  will  constitute  valid and
binding  obligations of the Company,  enforceable  against the Company
in  accordance  with their terms,  except as the  enforcement  thereof



may  be  limited  by  bankruptcy,   insolvency   (including,   without
limitation,    all   laws   relating   to    fraudulent    transfers),
reorganization,  moratorium or similar laws  affecting  enforcement of
creditors' rights  generally  and  except as  enforcement  thereof is
subject  to  general  principles  of  equity  (regardless  of  whether
enforcement  is considered in a proceeding in equity or at law),  will
be  entitled  to the  benefits  of the  Indenture,  will have the same
terms as and will  constitute  the same series of Securities  (as such
terms  are  defined  in  the  Indenture)  as the  May  Notes  for  all
purposes  under the  Indenture  and will have the same CUSIP number as
the May Notes.

      The Indenture has been duly qualified under the 1939 Act.

      The   Registration   Statement,   including   any  Rule   462(b)
Registration  Statement,  has been declared  effective  under the 1933
Act; any required  filing of the  Prospectus  pursuant to  Rule 424(b)
has been made in the manner and within  the time  period  required  by
Rule  424(b);  and,  to the  best  of our  knowledge,  no  stop  order
suspending  the  effectiveness  of the  Registration  Statement or any
Rule 462(b)  Registration  Statement  has been  issued  under the 1933
Act and no  proceedings  for that purpose have been  instituted or are
pending or threatened by the Commission.

      The   Registration   Statement,   including   any  Rule   462(b)
Registration  Statement,  the  Prospectus,   excluding  the  documents
incorporated  by reference  therein,  and each amendment or supplement
to the Registration  Statement and Prospectus,  as of their respective
effective  or  issue  dates  (other  than  the  financial  statements,
statistical  data  and  supporting   schedules   included  therein  or
omitted  therefrom,  as to which we need express no opinion)  complied
as to form in all  material  respects  with  the  requirements  of the
1933 Act and the 1933 Act Regulations.

      The  documents  incorporated  by  reference  in  the  Prospectus
(other  than  the  financial   statements  and  supporting   schedules
included  therein or omitted  therefrom,  as to which we need  express
no opinion),  when they were filed with the Commission  complied as to
form in all material  respects with the  requirements  of the 1934 Act
and the rules and regulations of the Commission thereunder.

      The Securities and the Indenture  conform as to legal matters in
all material  respects to the  descriptions  thereof  contained in the
Prospectus.

      To the best of our  knowledge,  other  than as set  forth in the
Prospectus,  there is not  pending or  threatened  any  action,  suit,
proceeding,  inquiry  or  investigation,  to which the  Company or any
subsidiary  thereof  is a  party,  or to  which  the  property  of the
Company or any  subsidiary  thereof is  subject,  before or brought by
any court or governmental  agency or body,  which might  reasonably be
expected  to result  in a  Material  Adverse  Effect,  or which  might
reasonably  be  expected  to  materially  and  adversely   affect  the
properties or assets thereof or the  consummation of the  transactions
contemplated  in the  Purchase  Agreement  or the  performance  by the
Company of its obligations thereunder.

      The  information in the  Prospectus  under  "Description  of the
Senior  Debentures" and in the  Registration  Statement under Item 15,
to the extent that it constitutes  matters of law,  summaries of legal
matters,  the  Company's  charter  or  legal  proceedings,   or  legal
conclusions,  has been  reviewed by us and is correct in all  material
respects.



      All  descriptions in the  Registration  Statement of franchises,
contracts,  indentures,  mortgages, loan agreements,  notes, leases or
other  instruments  to which the  Company  or any of its  subsidiaries
are a party,  to the extent  that they  describe  legal  matters,  are
accurate in all material  respects;  and to the best of our knowledge,
there are no such  documents  required to be  described or referred to
in the  Registration  Statement  or to be  filed as  exhibits  thereto
other  than  those  described  or  referred  to  therein  or  filed or
incorporated by reference as exhibits thereto.

      To the best of our  knowledge,  the Company is not in  violation
of its  charter or by-laws  and no  default by the  Company  exists in
the  due  performance  or  observance  of  any  material   obligation,
agreement,   covenant  or  condition   contained   in  any   contract,
indenture,  mortgage,  loan agreement,  note, lease or other agreement
or  instrument  that is described  or referred to in the  Registration
Statement or  Prospectus or filed or  incorporated  by reference as an
exhibit to the Registration Statement.

      No filing with, or authorization,  approval,  consent,  license,
order,  registration,  qualification  or decree of, any domestic court
or  governmental  authority or agency (other than such as have already
been  obtained  and  such  as may be  required  under  the  applicable
securities laws of the various  jurisdictions  in which the Securities
will be  offered  or sold and the 1935 Act  (solely  with  respect  to
filings  required  to be made with the  Commission  subsequent  to the
Closing  Time),  as to which we need  express no opinion) is necessary
or required in connection  with the due  authorization,  execution and
delivery of the  Purchase  Agreement  or the  Indenture by the Company
or for the offering, issuance, sale or delivery of the Securities.

      The  execution,   delivery  and   performance  of  the  Purchase
Agreement,  the DTC  Agreement,  the Indenture and the  Securities and
the  consummation  of the  transactions  contemplated  in the Purchase
Agreement and in the  Registration  Statement  (including the issuance
and sale of the  Securities  and the use of the proceeds from the sale
of the  Securities  as described in the  Prospectus  under the caption
"Use  Of   Proceeds")   and   compliance   by  the  Company  with  its
obligations  under  the  Purchase  Agreement,  the  Indenture  and the
Securities  do not and will not,  whether  with or without  the giving
of  notice or lapse of time or both,  conflict  with or  constitute  a
breach  of, or  default  or  Repayment  Event (as  defined  in Section
1(a)(xii) of the Purchase  Agreement)  under or result in the creation
or imposition  of any lien,  charge or  encumbrance  upon any property
or assets of the  Company  pursuant to those  agreements  set forth on
Schedule A hereto  (except  for such  conflicts,  breaches or defaults
or liens,  charges  or  encumbrances  that  would not have a  Material
Adverse  Effect),  nor will such action result in any violation of the
provisions  of the  charter  or  by-laws,  or  similar  organizational
documents,  of the Company,  or any  applicable  law,  statute,  rule,
regulation,  judgment,  order,  writ or  decree,  known to us,  of any
U.S.   government,   government   instrumentality  or  court,   having
jurisdiction  over the  Company  or any of its  properties,  assets or
operations.

      The  Company  is  not  an  "investment  company"  or  an  entity
"controlled"  by an  "investment  company,"  as such terms are defined
in the 1940 Act.

      The issuance of the  Securities  complies with all  requirements
of the  Securities  and Exchange  Commission's  Release No.  35-27456,
70-9837,  dated  as of  October  24,  2001,  as  supplemented  by  the
Commission's  Release  No.  35-27863,  70-9375,  dated  as of June 25,
2004.




      Nothing has come to our attention  that would lead us to believe
that  the  Registration  Statement  or  any  amendment  or  supplement
thereto  (except for  financial  statements  and  schedules  and other
financial or statistical  data included or  incorporated  by reference
therein   or  omitted   therefrom,   as  to  which  we  need  make  no
statement),  at the  time  such  Registration  Statement  or any  such
amendment  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  or any  amendment  or  supplement
thereto  (except for  financial  statements  and  schedules  and other
financial or statistical  data included or  incorporated  by reference
therein   or  omitted   therefrom,   as  to  which  we  need  make  no
statement),  at the time the  Prospectus  was issued,  at the time any
such amended or  supplemented  prospectus was issued or at the Closing
Time,  included or includes 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.

In rendering  this  opinion,  we relied as to matters of fact (but not
as  to  legal  conclusions),  to  the  extent  we  deemed  proper,  on
certificates  of  responsible  officers  of  the  Company  and  public
officials.  We have also relied on the legal  opinion of Iowa  counsel
for certain  matters of Iowa corporate law and the Company's  in-house
counsel for certain matters of state regulatory law.
