the date on which such Exchange Note is disposed of by a Broker-Dealer pursuant

Statement (including the delivery of the Prospectus contained therein).

SECTION 2. Holders

         A Person is deemed to be a holder of Transfer Restricted Securities
(each, a "Holder") whenever such Person owns Transfer Restricted Securities.

SECTION 3. Registered Exchange Offer

         (a) Unless the Exchange Offer shall not be permitted by applicable
federal law (after the procedures set forth in Section 6(a)(i) below have been
complied with), the Company shall (i) use commercially reasonable efforts to
cause the Exchange Offer Registration Statement to be filed with the Commission
as soon as practicable after the Closing Date, but in no event later than 120
days after the Closing Date (such 120th day being the "Filing Deadline"), (ii)
use commercially reasonable efforts to cause such Exchange Offer Registration
Statement to become effective at the earliest possible time, but in no event
later than 210 days after the Closing Date (such 210th day being the
"Effectiveness Deadline"), (iii) in connection with the foregoing, (A) file all
pre-effective amendments to such Exchange Offer Registration Statement as may be
necessary in order to cause it to become effective, (B) file, if applicable, a
post-effective amendment to such Exchange Offer Registration Statement pursuant
to Rule 430A under the Act and (C) cause all necessary filings, if any, in
connection with the registration and qualification of the Exchange Notes to be
made under the Blue Sky laws of such jurisdictions as are necessary to permit
Consummation of the Exchange Offer, and (iv) upon the effectiveness of such
Exchange Offer Registration Statement, commence and Consummate the Exchange
Offer. The Exchange Offer shall be on the appropriate form permitting (x)
registration of the Exchange Notes to be offered in exchange for the Notes that
are Transfer Restricted Securities and (y) resales of Exchange Notes by
Broker-Dealers that tendered into the Exchange Offer Notes that such
Broker-Dealer acquired for its own account as a result of market making
activities or other trading activities (other than Notes acquired directly from
the Company or any of its Affiliates) as contemplated by Section 3(c) below.

         (b) The Company shall use commercially reasonable efforts to cause the
Exchange Offer Registration Statement to be effective continuously, and shall
keep the Exchange Offer open for a period of not less than the minimum period
required under applicable federal and state securities laws to Consummate the
Exchange Offer; provided, however, that in no event shall such period be less
than 30 days. The Company shall cause the Exchange Offer to comply with all
applicable federal and state securities laws. No securities other than the
Exchange Notes shall be included in the Exchange Offer Registration Statement.
The Company shall use commercially reasonable efforts to cause the Exchange
Offer to be Consummated on the earliest practicable date after the Exchange
Offer

                                       4
<PAGE>

Registration Statement has become effective, but in no event later than 30
Business Days thereafter (such 30th day being the "Consummation Deadline").

         (c) The Company shall include a "Plan of Distribution" section in the
Prospectus contained in the Exchange Offer Registration Statement and indicate
therein that any Broker-Dealer who holds Transfer Restricted Securities that
were acquired for the account of such Broker-Dealer as a result of market-making
activities or other trading activities (other than Notes acquired directly from
the Company or any Affiliate of the Company), may exchange such Transfer
Restricted Securities pursuant to the Exchange Offer. Such "Plan of
Distribution" section shall also contain all other information with respect to
such sales by such Broker-Dealers that the Commission may require in order to
permit such sales pursuant thereto, but such "Plan of Distribution" shall not
name any such Broker-Dealer or disclose the amount of Transfer Restricted
Securities held by any such Broker-Dealer, except to the extent required by the
Commission.

         Because such Broker-Dealer may be deemed to be an "underwriter" within
the meaning of the Act and must, therefore, deliver a prospectus meeting the
requirements of the Act in connection with its initial sale of any Exchange
Notes received by such Broker-Dealer in the Exchange Offer, the Company shall
permit the use of the Prospectus contained in the Exchange Offer Registration
Statement by such Broker-Dealer to satisfy such prospectus delivery requirement.
To the extent necessary to ensure that the prospectus contained in the Exchange
Offer Registration Statement is available for resales of Exchange Notes by
Broker-Dealers, the Company agrees to use commercially reasonable efforts to
keep the Exchange Offer Registration Statement continuously effective,
supplemented, amended and current as required by and subject to the provisions
of Section 6(a) and (c) hereof and in conformity with the requirements of this
Agreement, the Act and the policies, rules and regulations of the Commission as
announced from time to time, for a period of 180 days from the Consummation
Deadline or such shorter period as will terminate when all Transfer Restricted
Securities covered by such Registration Statement have been sold pursuant
thereto. The Company shall provide sufficient copies of the latest version of
such Prospectus to such Broker-Dealers, promptly upon request, and in no event
later than one day after such request, at any time during such period.

SECTION 4. Shelf Registration

         (a) Shelf Registration. If (i) the Exchange Offer is not permitted by
applicable law or Commission policy after the Company has complied with the
procedures set forth in Section 6(a)(i) below or (ii) any Holder of Notes which
are Transfer Restricted Securities shall notify the Company prior to the 20th
Business Day following the Consummation Deadline that (A) such Holder is
prohibited by law or Commission policy from participating in the Exchange Offer,
(B) such Holder may not resell the Exchange Notes acquired by it in the Exchange
Offer to the public without delivering a prospectus, and the Prospectus
contained in the Exchange Offer Registration Statement is not appropriate or
available for such resales by such Holder, or (C) such Holder is a Broker-Dealer
and holds Notes acquired directly from the Company or any of the Company's
affiliates, then the Company shall:

                  (x) use commercially reasonable efforts to cause to be filed,
         on or prior to the 60th day after the date on which the Company
         receives the notice specified in clause (a)(ii) above (such 60th day
         being the "Filing Deadline"), a shelf registration statement pursuant
         to

                                       5
<PAGE>

         Rule 415 under the Act (which may be an amendment to the Exchange Offer
         Registration Statement (the "Shelf Registration Statement")), relating
         to all Transfer Restricted Securities, and

                  (y) shall use commercially reasonable efforts to cause such
         Shelf Registration Statement to become effective on or prior to the
         120th day after the date on which the Company receives notice under (x)
         above (such 120th day being the "Effectiveness Deadline").

         If, after the Company has filed an Exchange Offer Registration
Statement that satisfies the requirements of Section 3(a) above, the Company is
required to file and make effective a Shelf Registration Statement solely
because the Exchange Offer is not permitted under applicable federal law (i.e.,
clause (a)(i) above), then the filing of the Exchange Offer Registration
Statement shall be deemed to satisfy the requirements of clause (x) above;
provided that, in such event, the Company shall remain obligated to meet the
Effectiveness Deadline set forth in clause (y) above.

         To the extent necessary to ensure that the Shelf Registration Statement
is available for resales of Transfer Restricted Securities by the Holders
thereof entitled to the benefit of this Section 4(a) and the other securities
required to be registered therein pursuant to Section 6(b)(ii) hereof, the
Company shall use commercially reasonable efforts to keep any Shelf Registration
Statement required by this Section 4(a) continuously effective, supplemented,
amended and current as required by and subject to the provisions of Sections
6(b) and (c) hereof and in conformity with the requirements of this Agreement,
the Act and the policies, rules and regulations of the Commission as announced
from time to time, for a period of at least two years following the Closing
Date, or such shorter period as will terminate when all Transfer Restricted
Securities covered by such Shelf Registration Statement have been sold pursuant
thereto.

         (b) Provision by Holders of Certain Information in Connection with the
Shelf Registration Statement. No Holder of Transfer Restricted Securities may
include any of its Transfer Restricted Securities in any Shelf Registration
Statement pursuant to this Agreement unless and until such Holder furnishes to
the Company in writing, within 10 days after receipt of a request therefor, the
information specified in Item 507 or 508 of Regulation S-K, as applicable, of
the Act for use in connection with any Shelf Registration Statement or
Prospectus or preliminary Prospectus included therein. No Holder of Transfer
Restricted Securities shall be entitled to liquidated damages pursuant to
Section 5 hereof unless and until such Holder shall have provided all such
information. Each selling Holder agrees to promptly furnish additional
information required to be disclosed in order to make the information previously
furnished to the Company by such Holder not materially misleading.

         (c) Prohibitions Against Sales. Notwithstanding anything to the
contrary in this Section 4 or in Section 3(c), but subject to compliance with
Section 5, the Company may, by delivering written notice to the Holders,
prohibit offers and sales of Transfer Restricted Securities pursuant to the
Shelf Registration Statement at any time if (A)(i) the Company is in possession
of material non-public information relating to the Company, (ii) the Company
determines (based on advice of counsel) that such prohibition is necessary in
order to avoid a requirement to disclose such material non-public information to
the public and (iii) the Company determines in good faith that public disclosure
of such material non-public information would not be in the best interests of
the Company and its

                                       6
<PAGE>

stockholders or (B)(i) the Company has made a public announcement relating to an
acquisition or business combination transaction including the Company and/or one
or more of its subsidiaries that is material to the Company and its subsidiaries
taken as a whole and (ii) the Company determines in good faith that (x) offers
and sales of Transfer Restricted Securities pursuant to the Shelf Registration
Statement prior to the consummation of such transaction (or such earlier date as
the Company shall determine) is not in the best interests of the Company and its
stockholders or (y) it would be impracticable at the time to obtain any
financial statements relating to such acquisition or business combination
transaction that would be required to be set forth in the Shelf Registration;
provided, however, that upon (i) the public disclosure by the Company of the
material non-public information described in clause (A) of this paragraph or
(ii) the consummation, abandonment or termination of, or the availability of the
required financial statements with respect to, a transaction described in clause
(B) of this paragraph, the suspension of the use of the Shelf Registration
Statement pursuant to this Section 4(c) shall cease and the Company shall
promptly comply with Section 6(c)(ii) hereof and notify Holders that
dispositions of Transfer Restricted Securities may be resumed.

SECTION 5. Liquidated Damages

         If (i) any Registration Statement required by this Agreement is not
filed with the Commission on or prior to the applicable Filing Deadline set
forth in Section 3(a) or 4(a), as the case may be, (ii) any such Registration
Statement has not been declared effective by the Commission on or prior to the
applicable Effectiveness Deadline set forth in Section 3(a) or 4(a), as the case
may be, (iii) the Exchange Offer has not been Consummated on or prior to the
Consummation Deadline or (iv) any Registration Statement required by this
Agreement is filed and declared effective but shall thereafter cease to be
effective or fail to be usable for its intended purpose without being succeeded
reasonably promptly by a post-effective amendment to such Registration Statement
that cures such failure and that is itself declared effective reasonably
promptly (including as a result of a prohibition against sales of Transfer
Restricted Securities pursuant to Section 4(c) hereof at any time for a period
of time which shall exceed 30 days in the aggregate during any 3-month period or
90 days in the aggregate during any 365-day period) (each such event referred to
in clauses (i) through (iv), a "Registration Default"), then the Company hereby
jointly and severally agrees to pay to each Holder of Transfer Restricted
Securities affected thereby liquidated damages in an amount equal to 0.25% per
annum in principal amount of Transfer Restricted Securities held by such Holder
for each week or portion thereof that the Registration Default continues for the
first 90-day period immediately following the occurrence of such Registration
Default. The amount of the liquidated damages shall increase by 0.25% per annum
in principal amount of Transfer Restricted Securities with respect to each
subsequent 90-day period until all Registration Defaults have been cured, up to
a maximum amount of liquidated damages of 1.00% per annum in principal amount of
Transfer Restricted Securities; provided that the Company shall in no event be
required to pay liquidated damages for more than one Registration Default at any
given time. If, after the cure of all Registration Defaults then in effect,
there is a subsequent Registration Default, the rate of Additional Interest for
such subsequent Registration Default shall initially be 0.25%, regardless of the
Additional Interest rate in effect with respect to any prior Registration
Default at the time of the cure of such Registration Default. Notwithstanding
anything to the contrary set forth herein, (1) upon filing of the Exchange Offer
Registration Statement (and/or, if applicable, the Shelf Registration
Statement), in the case of (i) above, (2) upon the effectiveness of the Exchange
Offer Registration Statement (and/or, if applicable, the Shelf Registration
Statement), in the case of (ii) above, (3) upon Consummation of the Exchange

                                       7
<PAGE>

Offer, in the case of (iii) above, or (4) upon the filing of a post-effective
amendment to the Registration Statement or an additional Registration Statement
that causes the Exchange Offer Registration Statement (and/or, if applicable,
the Shelf Registration Statement) to again be declared effective or made usable
in the case of (iv) above, the liquidated damages payable with respect to the
Transfer Restricted Securities as a result of such clause (i), (ii), (iii) or
(iv), as applicable, shall cease.

         All accrued liquidated damages shall be paid to the Holders entitled
thereto, in the manner provided for the payment of interest in the Indenture, on
each Interest Payment Date, as more fully set forth in the Indenture and the
Notes. Notwithstanding the fact that any securities for which liquidated damages
are due cease to be Transfer Restricted Securities, all obligations of the
Company to pay liquidated damages with respect to securities shall survive until
such time as such obligations with respect to such securities shall have been
satisfied in full.

SECTION 6. Registration Procedures

         (a) Exchange Offer Registration Statement. In connection with the
Exchange Offer, the Company shall (x) comply with all applicable provisions of
Section 6(c) below, (y) use commercially reasonable efforts to effect such
exchange and to permit the resale of Exchange Notes by Broker-Dealers that
tendered in the Exchange Offer Notes that such Broker-Dealer acquired for its
own account as a result of its market making activities or other trading
activities (other than Notes acquired directly from the Company or any of its
Affiliates) being sold in accordance with the intended method or methods of
distribution thereof, and (z) comply with all of the following provisions:

                  (i)      If, following the date hereof there has been
         announced a change in Commission policy with respect to exchange offers
         such as the Exchange Offer, that in the reasonable opinion of counsel
         to the Company raises a substantial question as to whether the Exchange
         Offer is permitted by applicable federal law, if and to the extent
         reasonable under the circumstances, the Company hereby agrees to seek a
         no-action letter or other favorable decision from the Commission
         allowing the Company to Consummate an Exchange Offer for such Transfer
         Restricted Securities. If and to the extent reasonable under the
         circumstances, the Company hereby agrees to pursue the issuance of such
         a decision to the Commission staff level.

                  (ii)     As a condition to its participation in the Exchange
         Offer, each Holder of Transfer Restricted Securities (including,
         without limitation, any Holder who is a Broker Dealer) shall furnish,
         upon the request of the Company, prior to the Consummation of the
         Exchange Offer, a written representation to the Company (which may be
         contained in the letter of transmittal contemplated by the Exchange
         Offer Registration Statement) to the effect that (A) it is not an
         Affiliate of the Company, (B) it is not engaged in, and does not intend
         to engage in, and has no arrangement or understanding with any Person
         to participate in, a distribution of the Exchange Notes to be issued in
         the Exchange Offer and (C) it is acquiring the Exchange Notes in its
         ordinary course of business. As a condition to its participation in the
         Exchange Offer each Holder that is a Broker-Dealer using the Exchange
         Offer to participate in a distribution of the Exchange Notes shall
         acknowledge and agree that, if the resales are of Exchange Notes
         obtained by such Holder in exchange for Notes acquired directly from
         the Company or an Affiliate thereof, it (1) could not, under Commission
         policy

                                       8
<PAGE>

         as in effect on the date of this Agreement, rely on the position of the
         Commission enunciated in Morgan Stanley and Co., Inc. (available June
         5, 1991) and Exxon Capital Holdings Corporation (available May 13,
         1988), as interpreted in the Commission's letter to Shearman & Sterling
         dated July 2, 1993, and similar no-action letters (including, if
         applicable, any no-action letter obtained pursuant to clause (i)
         above), and (2) must comply with the registration and prospectus
         delivery requirements of the Act in connection with a secondary resale
         transaction and that such a secondary resale transaction must be
         covered by an effective registration statement containing the selling
         security holder information required by Item 507 or 508, as applicable,
         of Regulation S-K.

                  (iii)    Prior to effectiveness of the Exchange Offer
         Registration Statement, the Company shall provide a supplemental letter
         to the Commission (A) stating that the Company is registering the
         Exchange Offer in reliance on the position of the Commission enunciated
         in Exxon Capital Holdings Corporation (available May 13, 1988), Morgan
         Stanley and Co., Inc. (available June 5, 1991) as interpreted in the
         Commission's letter to Shearman & Sterling dated July 2, 1993, and, if
         applicable, any no-action letter obtained pursuant to clause (i) above,
         (B) including a representation that the Company has not entered into
         any arrangement or understanding with any Person to distribute the
         Exchange Notes to be received in the Exchange Offer and that, to the
         best of the Company's information and belief, each Holder participating
         in the Exchange Offer is acquiring the Exchange Notes in its ordinary
         course of business and has no arrangement or understanding with any
         Person to participate in the distribution of the Exchange Notes
         received in the Exchange Offer and (C) any other undertaking or
         representation required by the Commission as set forth in any no-action
         letter obtained pursuant to clause (i) above, if applicable.

         (b) Shelf Registration Statement. In connection with the Shelf
Registration Statement, the Company shall:

                  (i)      comply with all the provisions of Section 6(c) below
         and use commercially reasonable efforts to effect such registration to
         permit the sale of the Transfer Restricted Securities being sold in
         accordance with the intended method or methods of distribution thereof
         (as indicated in the information furnished to the Company pursuant to
         Section 4(b) hereof), and pursuant thereto the Company will prepare and
         file with the Commission a Registration Statement relating to the
         registration on any appropriate form under the Act, which form shall be
         available for the sale of the Transfer Restricted Securities in
         accordance with the intended method or methods of distribution thereof
         within the time periods and otherwise in accordance with the provisions
         hereof, and

                  (ii)     issue, upon the request of any Holder or purchaser of
         Notes covered by any Shelf Registration Statement contemplated by this
         Agreement, Exchange Notes having an aggregate principal amount equal to
         the aggregate principal amount of Notes sold pursuant to the Shelf
         Registration Statement and surrendered to the Company for cancellation;
         the Company shall register Exchange Notes on the Shelf Registration
         Statement for this purpose and issue the Exchange Notes to the
         purchaser(s) of securities subject to the Shelf Registration Statement
         in the names as such purchaser(s) shall designate.

         (c) General Provisions. In connection with any Registration Statement
and any related Prospectus required by this Agreement, the Company shall:

                  (i)      use commercially reasonable efforts to keep such
         Registration Statement continuously effective and provide all requisite
         financial statements for the period specified in Section 3 or 4 of this
         Agreement, as applicable. Upon the occurrence of any event subject to
         Section 4(c) above that would cause any such Registration Statement or
         the Prospectus contained therein (A) to contain an untrue statement of
         material fact or omit to state any material fact necessary to make the
         statements therein not misleading or (B) not to be effective and usable
         for resale of Transfer Restricted Securities during the period required
         by this Agreement, the Company shall file promptly an appropriate
         amendment to such Registration Statement curing such defect, and, if
         Commission review is required, use commercially reasonable efforts to
         cause such amendment to be declared effective as soon as practicable.

                  (ii)     subject to Section 4(c) above, prepare and file with
         the Commission such amendments and post-effective amendments to the
         applicable Registration Statement as may be necessary to keep such
         Registration Statement effective for the applicable period set forth in
         Section 3 or 4 hereof, as the case may be; cause the Prospectus to be
         supplemented by any required Prospectus supplement, and as so
         supplemented to be filed pursuant to Rule 424 under the Act, and to
         comply fully with Rules 424, 430A and 462, as applicable, under the Act
         in a timely manner; and comply with the provisions of the Act with
         respect to the disposition of all securities covered by such
         Registration Statement during the applicable period in accordance with
         the intended method or methods of distribution by the sellers thereof
         set forth in such Registration Statement or supplement to the
         Prospectus;

                  (iii)    advise each Holder that is a Broker-Dealer and each
         Initial Purchaser who is required to deliver a prospectus in connection
         with sales or market making activities (an "Affiliated Market Maker")
         to the extent the Company is aware of the same, promptly and, if
         requested by such Person, confirm such advice in writing, (A) when the
         Prospectus or any Prospectus supplement or post-effective amendment has
         been filed, and, with respect to any applicable Registration Statement
         or any post-effective amendment thereto, when the same has become
         effective, (B) of any request by the Commission for amendments to the
         Registration Statement or amendments or supplements to the Prospectus
         or for additional information relating thereto, (C) of the issuance by
         the Commission of any stop order suspending the effectiveness of the
         Registration Statement under the Act or of the suspension by any state
         securities commission of the qualification of the Transfer Restricted
         Securities for offering or sale in any jurisdiction, or the initiation
         of any proceeding for any of the preceding purposes, (D) of the
         existence of any fact or the happening of any event that makes any
         statement of a material fact made in the Registration Statement, the
         Prospectus, any amendment or supplement thereto or any document
         incorporated by reference therein untrue, or that requires the making
         of any additions to or changes in the Registration Statement in order
         to make the statements therein not misleading, or that requires the
         making of any additions to or changes in the Prospectus in order to
         make the statements therein, in the light of the circumstances under
         which they were made, not misleading. If at any time the Commission
         shall issue any stop order suspending the effectiveness of the
         Registration

                                       10

         Statement, or any state securities commission or other regulatory
         authority shall issue an order suspending the qualification or
         exemption from qualification of the Transfer Restricted Securities
         under state securities or Blue Sky laws, the Company shall use
         commercially reasonable efforts to obtain the withdrawal or lifting of
         such order at the earliest possible time;

                  (iv)     subject to Section 6(c)(i), if any fact or event
         contemplated by Section 6(c)(iii)(D) above shall exist or have
         occurred, prepare a supplement or post-effective amendment to the
         Registration Statement or related Prospectus or any document
         incorporated therein by reference or file any other required document
         so that, as thereafter delivered to the purchasers of Transfer
         Restricted Securities, the Prospectus will not contain an untrue
         statement of a material fact or omit to state any material fact
         necessary to make the statements therein, in the light of the
         circumstances under which they were made, not misleading;

                  (v)      upon request, furnish to each Holder and each
         Affiliated Market Maker in connection with such exchange or sale, if
         any, before filing with the Commission, copies of any Registration
         Statement or any Prospectus included therein or any amendments or
         supplements to any such Registration Statement or Prospectus, which
         documents will be subject to the review and comment of such Persons in
         connection with such sale, if any, for a period of at least five
         Business Days, and the Company will not file any such Registration
         Statement or Prospectus or any amendment or supplement to any such
         Registration Statement or Prospectus to which such Persons shall
         reasonably object within five Business Days after the receipt thereof;

                  (vi)     make available, at reasonable times, for inspection
         by each Holder and each Affiliated Market Maker and any attorney or
         accountant retained by such Persons, all financial and other records,
         pertinent corporate documents of the Company and cause the Company's
         officers, directors and employees to supply all information reasonably
         requested by any such Persons, attorney or accountant in connection
         with such Registration Statement or any post-effective amendment
         thereto subsequent to the filing thereof and prior to its
         effectiveness;

                  (vii)    if requested by any Holders in connection with such
         exchange or sale or any Affiliated Market Maker, promptly include in
         any Registration Statement or Prospectus, pursuant to a supplement or
         post-effective amendment if necessary, such information as such Persons

         of Distribution" of the Transfer Restricted Securities and the use of
         the Registration Statement or Prospectus for market making activities;
         and make all required filings of such Prospectus supplement or

         post-effective amendment;

                  (viii)   upon the request furnish to such Holder in connection
         with such exchange or sale and each Affiliated Market Maker, without
         charge, at least one copy of the Registration Statement, as first filed

                  (ix)     deliver to each Holder and each Affiliated Market
         Maker without charge, as many copies of the Prospectus (including each
         preliminary prospectus) and any amendment or supplement thereto as such
         Persons reasonably may request; the Company hereby consents to the use
         (in accordance with law) of the Prospectus and any amendment or

         offering and the sale of the Transfer Restricted Securities covered by
         the Prospectus or any amendment or supplement thereto and all market

         be reasonably requested by any such Holder or Affiliated Market Maker
         in connection with any sale or resale pursuant to any applicable
         Registration Statement. In connection with the exchange or disposition
         of Transfer Restricted Securities pursuant to a Registration Statement,
         the Company shall:

                           (A) upon request of any Holder, furnish (or in the
                  case of paragraphs (2) and (3), use commercially reasonable
                  efforts to cause to be furnished) to each Person, upon
                  Consummation of the Exchange Offer or upon the effectiveness
                  of the Shelf Registration Statement, as the case may be:

                                    (1) a certificate, dated such date, signed
                           on behalf of the Company by (x) the President or any
                           Vice President and (y) a principal financial or
                           accounting officer of the Company, confirming, as of
                           the date thereof, the matters set forth in Sections
                           6(k)(iii) and (iv), 6(l) and 6(o) of the Purchase
                           Agreement and such other similar matters as such
                           Person may reasonably request;

                                    (2) an opinion, dated the date of
                           Consummation of the Exchange Offer or the date of
                           effectiveness of the Shelf Registration Statement, as
                           the case may be, of counsel for the Company covering
                           matters similar to those set forth in the relevant
                           paragraphs of Section 6(d) and 6(e) of the Purchase
                           Agreement, and in any event including a statement to
                           the effect that such counsel has participated in
                           conferences with officers and other representatives
                           of the Company, representatives of the independent
                           certified public accountants of the Company and the
                           Initial Purchasers and its representatives at which
                           the contents of the applicable Registration Statement
                           and related matters were discussed and, although such
                           counsel is not passing upon and assumes no
                           responsibility for, the accuracy, completeness or
                           fairness of the statements contained in the
                           applicable Registration Statement (except as
                           indicated above), on the basis of the foregoing, no
                           facts came to such counsel's attention which led such
                           counsel to believe that the applicable Registration
                           Statement, at the time such Registration Statement or
                           any post-effective amendment thereto became effective
                           and, in the case of the Exchange Offer Registration
                           Statement, as of the date of Consummation of the
                           Exchange Offer, contained an untrue statement of a
                           material fact or

                                       12
<PAGE>

                           omitted to state 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, or that the
                           Prospectus contained in such Registration Statement
                           as of its date and, in the case of the opinion dated
                           the date of Consummation of the Exchange Offer, as of
                           the date of Consummation, 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, not misleading. Without
                           limiting the foregoing, such counsel may state
                           further that such counsel assumes no responsibility
                           for, and has not independently verified, the
                           accuracy, completeness or fairness of the financial
                           statements and other financial data included in any
                           Registration Statement contemplated by this Agreement
                           or the related Prospectus; and

                                    (3) a customary comfort letter, dated the
                           date of Consummation of the Exchange Offer, or as of
                           the date of effectiveness of the Shelf Registration
                           Statement, as the case may be, from the Company's
                           independent accountants, in the customary form and
                           covering matters of the type customarily covered in
                           comfort letters to underwriters in connection with
                           underwritten offerings, and affirming the matters set
                           forth in the comfort letters delivered pursuant to
                           Sections 6(i) and (j) of the Purchase Agreement; and

                           (B) deliver such other documents and certificates as
                  may be reasonably requested by the selling Holders to evidence
                  compliance with the matters covered in clause (A) above and
                  with any customary conditions contained in any agreement
                  entered into by the Company pursuant to this clause (x);

                  (xi)     prior to any public offering of Transfer Restricted
         Securities, cooperate with the selling Holders and their counsel in
         connection with the registration and qualification of the Transfer
         Restricted Securities under the securities or Blue Sky laws of such
         jurisdictions as the selling Holders may request and do any and all
         other acts or things necessary or advisable to enable the disposition
         in such jurisdictions of the Transfer Restricted Securities covered by
         the applicable Registration Statement; provided, however, that the
         Company shall not be required to register or qualify as a foreign
         corporation where it is not now so qualified or to take any action that
         would subject it to the service of process in suits or to taxation,
         other than as to matters and transactions relating to the Registration
         Statement, in any jurisdiction where it is not now so subject;

                  (xii)    in connection with any sale of Transfer Restricted
         Securities that will result in such securities no longer being Transfer
         Restricted Securities, cooperate with the Holders to facilitate the
         timely preparation and delivery of certificates representing Transfer
         Restricted Securities to be sold and not bearing any restrictive
         legends; and to register such Transfer Restricted Securities in such
         denominations and such names as the selling Holders may request at
         least two Business Days prior to such sale of Transfer Restricted
         Securities;

<PAGE>

                  (xiii)   provide a CUSIP number for all Transfer Restricted
         Securities not later than the effective date of a Registration
         Statement covering such Transfer Restricted Securities and provide the
         Trustee under the Indenture with printed certificates for the Transfer
         Restricted Securities which are in a form eligible for deposit with The
         Depository Trust Company;

                  (xiv)    otherwise use commercially reasonable efforts to
         comply with all applicable rules and regulations of the Commission, and
         make generally available to its security holders with regard to any
         applicable Registration Statement, as soon as practicable, a
         consolidated earnings statement meeting the requirements of Rule 158
         (which need not be audited) covering a twelve-month period beginning
         after the effective date of the Registration Statement (as such term is
         defined in paragraph (c) of Rule 158 under the Act);

                  (xv)     cause the Indenture to be qualified under the TIA not
         later than the effective date of the first Registration Statement
         required by this Agreement and, in connection therewith, cooperate with
         the Trustee and the Holders to effect such changes to the Indenture as
         may be required for such Indenture to be so qualified in accordance
         with the terms of the TIA; and execute and use commercially reasonable
         efforts to cause the Trustee to execute, all documents that may be
         required to effect such changes and all other forms and documents
         required to be filed with the Commission to enable such Indenture to be
         so qualified in a timely manner; and

                  (xvi)    provide promptly to each Holder and Affiliated Market
         Maker, upon request, each document filed with the Commission pursuant
         to the requirements of Section 13 or Section 15(d) of the Exchange Act.

         (d) Restrictions on Holders. Each Holder agrees by acquisition of a
Transfer Restricted Security and each Affiliated Market Maker agrees that, upon
receipt of the notice referred to in Section 4(c) or 6(c)(iii)(C) or any notice
from the Company of the existence of any fact of the kind described in Section

forthwith discontinue disposition of Transfer Restricted Securities pursuant to
the applicable Registration Statement until (i)(A) such Person has received

shall be extended by a number of days equal to the number of days in the period
from and including the date of delivery of the Suspension Notice to the date of
delivery of the Recommencement Date.

be stated therein or necessary to make the statements therein not misleading and
shall reimburse each Holder Indemnified Party promptly upon demand for any legal
or other expenses reasonably incurred by that Holder Indemnified Party in
connection with investigating or preparing to defend or defending against or
appearing as a third party witness in connection with any such loss, claim,
damage, liability or action as such expenses are incurred;

                                       15
<PAGE>

provided, however, that the Company shall not be liable in any such case to the
extent that any such loss, claim, damage, liability or action arises out of or
is based upon (ii)(A) any untrue statement or alleged untrue statement in or (B)
omission or alleged omission from any Registration Statement, preliminary
prospectus or Prospectus (or any amendment or supplement thereto) provided by
the Company to any Holder or any prospective purchaser of Exchange Notes or
registered Notes in reliance upon and in conformity with written information
furnished to the Company by and of the Holders specifically for use therein.
This indemnity agreement is not exclusive and will be in addition to any
liability which the Company might otherwise have and shall not limit any rights
or remedies which may otherwise be available at law or in equity to each Holder
Indemnified Party.

         (b) Each Holder of Transfer Restricted Securities agrees, severally and
not jointly, shall indemnify and hold harmless the Company, its officers,
employees, representatives, agents, directors and each person, if any, who
controls (within the meaning of Section 15 of the Act or Section 20 of the
Exchange Act) the Company (collectively the "Company Indemnified Parties" and
each a "Company Indemnified Party") against any loss, claim, damage or
liability, joint or several, or any action in respect thereof, to which the
Company Indemnified Parties may become subject, under the Act or otherwise,
insofar as such loss, claim, damage, liability or action arises out of or is
based upon (i) any untrue statement or alleged untrue statement of a material
fact contained in any Registration Statement, preliminary prospectus or
Prospectus (or any amendment or supplement thereto) provided by the Company to
any Holder or any prospective purchaser of Exchange Notes or registered Notes,
or (ii) the omission or alleged omission to state therein (or in any amendment
or supplement thereto) a material fact required to be stated therein or
necessary to make the statements therein not misleading, but in each case only
to the extent that the untrue statement or alleged untrue statement or omission
or alleged omission was made in reliance upon and in conformity with written
information furnished to the Company by such Holder specifically for use
therein, and shall reimburse the Company Indemnified Parties for any legal or
other expenses reasonably incurred by such parties in connection with
investigating or preparing to defend or defending against or appearing as third
party witness in connection with any such loss, claim, damage, liability or
action as such expenses are incurred. In no event shall any Holder, its
officers, directors, employees, representatives and agents or any Person who
controls such Holder (within the meaning of Section 15 of the Act or Section 20
of the Exchange Act) be liable or responsible for any amount in excess of the
amount by which the total amount received by such Holder with respect to its
sale of Transfer Restricted Securities pursuant to a Registration Statement
exceeds (i) the amount paid by such Holder for such Transfer Restricted
Securities and (ii) the amount of any damages that such Holder, its officers,
directors, employees, representatives and agents or any Person who controls such
Holder (within the meaning of Section 15 of the Act or Section 20 of the
Exchange Act) has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission.

         (c) Promptly after receipt by an indemnified party under this Section 8
of notice of any claim or the commencement of any action, the indemnified party
shall, if a claim in respect thereof is to be made against the indemnifying
party under this Section 8, notify the indemnifying party in writing of the
claim or the commencement of that action; provided, however, that the failure to
notify the indemnifying party shall not relieve it from any liability which it
may have under this Section 8 except to the extent it has been materially
prejudiced by such failure; and, provided, further, that the failure to notify
the indemnifying party shall not relieve it from any liability which it may have
to an indemnified party otherwise than under this Section 8. If any such claim
or action shall be brought

                                       16
<PAGE>

against an indemnified party, and it shall notify the indemnifying party
thereof, the indemnifying party shall be entitled to participate therein and, to
the extent that it wishes, jointly with any other similarly notified
indemnifying party, to assume the defense thereof 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 8 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 any indemnified party
shall have the right to employ separate counsel in any such action and to
participate in the defense thereof but the fees and expenses of such counsel
shall be at the expense of such indemnified party unless (i) the employment
thereof has been specifically authorized by the indemnifying party in writing,
(ii) such indemnified party shall have been advised by such counsel that there
may be one or more legal defenses available to it which are different from or
additional to those available to the indemnifying party and in the reasonable
judgment of such counsel it is advisable for such indemnified party to employ
separate counsel or (iii) the indemnifying party has failed to assume the
defense of such action and employ counsel reasonably satisfactory to the
indemnified party, in which case, if such indemnified party notifies the
indemnifying party in writing that it elects to employ separate counsel at the
expense of the indemnifying party, the indemnifying party shall not have the
right to assume the defense of such action on behalf of such indemnified party,
it being understood, however, that the indemnifying party shall not, in
connection with any one such action or separate but substantially similar or
related actions in the same jurisdiction arising out of the same general
allegations or circumstances, be liable for the reasonable fees and expenses of
more than one separate firm of attorneys at any time for all such indemnified
parties, which firm shall be designated in writing by a majority of the Holders,
if the indemnified parties under this Section 8 consist of any Holder
Indemnified Parties, or by the Company if the indemnified parties under this
Section 8 consist of any Company Indemnified Parties. Each indemnified party, as
a condition of the indemnity agreements contained in Sections 8(a) and (b),
shall use all reasonable efforts to cooperate with the indemnifying party in the
defense of any such action or claim. No indemnifying party shall be liable for
any settlement of any such action effected without its written consent (which
consent shall not be unreasonably withheld), but if settled with its written
consent or if there be a final judgment for the plaintiff in any such action,
the indemnifying party agrees to indemnify and hold harmless any indemnified
party from and against any loss or liability by reason of such settlement or
judgment.

         (d) If the indemnification provided for in this Section 8 is
unavailable or insufficient to hold harmless an indemnified party under Section
8(a) or 8(b), then each indemnifying party shall, in lieu of indemnifying such
indemnified party, contribute to the amount paid or payable by such indemnified
party as a result of such loss, claim, damage or liability, or action in respect
thereof, (i)(A) in such proportion as shall be appropriate to reflect the
relative benefits received by the Company, on the one hand, and the Holder, on
the other, on their sale of Transfer Restricted Securities, or (B) if the
allocation provided by clause (i)(A) above is not permitted by applicable law,
in such proportion as is appropriate to reflect not only the relative benefits
referred to in clause (i)(A) above but also the relative fault of the Company,
on the one hand, and of the Holder, on the other, with respect to the statements
or omissions which resulted in such loss, claim, damage or liability, or action
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 statement of a material fact or the omission or
alleged omission to state a material fact relates to

                                       17
<PAGE>

information supplied by the Company on the one hand or the Holder on the other,
the intent of the parties and their relative knowledge, access to information
and opportunity to correct or prevent such untrue statement or omission. The
Company and the Initial Purchasers agree that it would not be just and equitable
if contributions pursuant to this Section 8(d) were to be determined by pro rata
allocation (even if the Holders were treated as one entity for such purpose) or
by any other method of allocation which does not take into account the equitable
considerations referred to herein. The amount paid or payable by an indemnified
party as a result of the loss, claim, damage or liability, or action in respect
thereof, referred to above in this Section 8(d) shall be deemed to include, for
purposes of this Section 8(d), 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 Section 8(d), (ii)(A) no
Holder, its officers, directors, representatives or agents or any Person, if
any, who controls such Holder shall be required to contribute any amount in
excess of the amount by which the total received by such Holder with respect to
the sale of Transfer Restricted Securities pursuant to a Registration Statement
exceeds (x) the amount paid by such Holder for such Transfer Restricted
Securities and (y) the amount of any damages which such Holder has otherwise
paid or become liable to pay by reason of any untrue or alleged untrue statement
or omission or alleged omission, and (B) any amount the Company would otherwise
be required to contribute shall be reduced by the amount the Company has
otherwise paid or become liable to pay by reason of any 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 Holders' obligations to contribute pursuant to
this Section 8(d) are several in proportion to the respective principal amount
of Transfer Restricted Securities held by each Holder hereunder and not joint.

         (e) The Company agrees that the indemnity and contribution provisions
of this Section 8 shall apply to Affiliated Market Makers to the same extent, on
the same conditions, as it applies to Holders.

SECTION 9. Rule 144A and Rule 144

         The Company agrees with each Holder, for so long as any Transfer
Restricted Securities remain outstanding and during any period in which the
Company (i) is not subject to Section 13 or 15(d) of the Exchange Act, to make
available, upon request of any Holder, to such Holder or beneficial owner of
Transfer Restricted Securities in connection with any sale thereof and any
prospective purchaser of such Transfer Restricted Securities designated by such
Holder or beneficial owner, the information required by Rule 144A(d)(4) under
the Act in order to permit resales of such Transfer Restricted Securities
pursuant to Rule 144A, and (ii) is subject to Section 13 or 15 (d) of the
Exchange Act, to make all filings required thereby in a timely manner in order
to permit resales of such Transfer Restricted Securities pursuant to Rule 144.

SECTION 10. Miscellaneous

         (a) Remedies. The Company acknowledges and agrees that any failure by
the Company to comply with its obligations under Sections 3 and 4 hereof may
result in material irreparable injury to the Initial Purchasers or the Holders
or Affiliated Market Makers for which there is no adequate remedy at law, that
it will not be possible to measure damages for such injuries precisely and that,
in the event of any such failure, the Initial Purchasers or any Holders or
Affiliated Market Makers may

                                       18
<PAGE>

obtain such relief as may be required to specifically enforce the Company's
obligations under Sections 3 and 4 hereof. The Company further agrees to waive
the defense in any action for specific performance that a remedy at law would be
adequate.

         (b) No Inconsistent Agreements. The Company will not, on or after the
date of this Agreement, enter into any agreement with respect to its securities
that is inconsistent with the rights granted to the Holders in this Agreement or
otherwise conflicts with the provisions hereof. The rights granted to the
Holders hereunder do not in any way conflict with and are not inconsistent with
the rights granted to the holders of the Company's securities under any
agreement in effect on the date hereof.

         (c) Amendments and Waivers. The provisions of this Agreement may not be
amended, modified or supplemented, and waivers or consents to or departures from
the provisions hereof may not be given unless (i) in the case of Section 5
hereof and this Section 10(c)(i), the Company has obtained the written consent
of Holders of all outstanding Transfer Restricted Securities and (ii) in the
case of all other provisions hereof, the Company has obtained the written
consent of Holders of a majority of the outstanding principal amount of Transfer
Restricted Securities (excluding Transfer Restricted Securities held by the
Company or its Affiliates). Notwithstanding the foregoing, a waiver or consent
to departure from the provisions hereof that relates exclusively to the rights
of Holders whose Transfer Restricted Securities are being tendered pursuant to
the Exchange Offer, and that does not affect directly or indirectly the rights
of other Holders whose Transfer Restricted Securities are not being tendered
pursuant to such Exchange Offer, may be given by the Holders of a majority of
the outstanding principal amount of Transfer Restricted Securities subject to
such Exchange Offer.

         (d) Third Party Beneficiary. The Holders and Affiliated Market Makers
shall be third party beneficiaries to the agreements made hereunder between the
Company, on the one hand, and the Initial Purchasers, on the other hand, and
shall have the right to enforce such agreements directly to the extent they may
deem such enforcement necessary or advisable to protect its rights or the rights
of Holders and Affiliated Market Makers hereunder.

         (e) Notices. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, first-class mail
(registered or certified, return receipt requested), telex, telecopier, or air
courier guaranteeing overnight delivery:

manner, whether by operation of law or otherwise, such Transfer Restricted
Securities shall be held subject to all of the terms of this Agreement, and by
taking and holding such Transfer Restricted Securities such Person shall be
conclusively deemed to have agreed to be bound by and to perform all of the

ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO THE
CONFLICT OF LAW RULES THEREOF.

         (j) Severability. In the event that any one or more of the provisions

remaining provisions contained herein shall not be affected or impaired thereby.

final expression of their agreement and intended to be a complete and exclusive
statement of the agreement and understanding of the parties hereto in respect of
the subject matter contained herein. There are no restrictions, promises,

Setting Forth Terms of
a Series of Debt Securities 

6.30% Senior
Debentures due 2034 

     _________________ 

Pursuant to the
Indenture
Dated as of August 20, 2003  

OFFICER’S
CERTIFICATE 

        The
undersigned, the Vice President and Treasurer of Interstate Power and Light Company, an
Iowa corporation (the “Company”), hereby certifies as provided below pursuant to
Section 301 of the Indenture, dated as of August 20, 2003 (the “Indenture”),
between the Company and J.P. Morgan Trust Company, National Association, successor, as
Trustee (the “Trustee”). This Officer’s Certificate, dated May 3, 2004, is
delivered, pursuant to authority granted to the undersigned by resolutions adopted January
28, 2004 by the Board of Directors of the Company, for the purpose of creating and setting
forth the terms of a series of Securities to be issued pursuant to the Indenture, and to
establish the form of such Securities in accordance with Section 201 of the Indenture.
Capitalized terms not otherwise defined herein are used as defined in the Indenture. 

    1.                     The
Board of Directors of the Company has authorized the creation by the Company           of
one or more series of Securities under the Indenture through one or more           Officer’s
Certificates and pursuant to such authorization and in accordance           with the
Indenture this Officer’s Certificate is being delivered to the           Trustee to
establish the terms of a series of Securities as set forth therein.  

    2.                     The
title of the series of Securities shall be “6.30% Senior Debentures due
          2034” (herein called the “Debentures”).  

    3.                     The
aggregate principal amount of the Debentures which may be authenticated and
          delivered under the Indenture shall be U.S. $100,000,000, except for Debentures
          authenticated and delivered upon registration of transfer of, or in exchange
          for, or in lieu of, other Debentures as provided in Sections 304, 305, 306, 406
          or 1206 of the Indenture. Notwithstanding the foregoing limit on the aggregate
          principal amount of the Debentures, the Debentures may be reopened in
accordance           with Section 301 of the Indenture.  

    4.                     The
Debentures shall be issuable in denominations of $1,000 and any integral
          multiple thereof.  

    5.                     Subject
to earlier redemption, the principal of the Debentures shall be payable           in U.S.
dollars on May 1, 2034.  

    6.                     The
Debentures shall bear interest at the rate of 6.30% per annum; such interest
          shall accrue from May 6, 2004 (or from and including the most recent interest
          payment date to which interest on the Debentures has been paid or provided
for);           the Interest Payment Dates on which such interest shall be payable shall
be May           1 and November 1 in each year, commencing November 1, 2004; the Regular
Record           Dates for the determination of Holders to whom interest is payable shall
be (1)           the Business Day next preceding each Interest Payment Date, if the
Debentures           remain in book-entry only form, or (2) on the fifteenth calendar day
before each           Interest Payment Date, if the Debentures do not remain in
book-entry only form.           Interest on the Debentures shall be payable in U.S.
dollars.  

    7.                     Pursuant
to the Indenture, the Trustee has been appointed as the Security           Registrar for
the Debentures. The Trustee is hereby further appointed as the           initial Paying
Agent and transfer agent of the Debentures. The principal of and           interest on
the Debentures shall be payable at the office of the Paying Agent,           which shall
initially be located in the Borough of Manhattan, The City of New           York.  

    8.                     The
Debentures shall be redeemable at the option of the Company at any time in
          whole or from time to time in part at a Redemption Price equal to the sum of
          (a) 100% of the principal amount of the Debentures being redeemed,
          (b) accrued interest thereon to the Redemption Date, and (c) the
          Make-Whole Amount, if any, with respect to such Debentures; provided, however,
          that installments of interest on Debentures due on an Interest Payment Date
          which occurs on or before any Redemption Date shall be payable to the Holders
of           such Debentures who were registered Holders as of the close of business on
the           Record Date immediately preceding such Interest Payment Date.  

    9.                     The
terms defined below shall, for all purposes of the Debentures under the
          Indenture and this Officer’s Certificate, have the meanings specified,
          unless the context clearly otherwise requires or unless otherwise indicated:  

        “Make-Whole
Amount” means, in connection with any optional redemption, the excess, if any, of (i)
the aggregate present value as of the date of such redemption of each dollar of principal
being redeemed and the amount of interest, exclusive of interest accrued to the Redemption
Date, that would have been payable in respect of each such dollar 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 such notice of redemption is given, from the respective dates on which such principal
and interest would have been payable if such redemption had not been made, to the
Redemption Date, over (ii) the aggregate principal amount of the Debentures being
redeemed. The Make-Whole Amount shall be calculated by the Company and set forth in a
certificate of an Authorized Officer delivered to the Trustee, and the Trustee shall be
entitled to rely on said certificate. 

        “Reinvestment
Rate” means .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
amount of the Debentures being redeemed. If no maturity exactly corresponds to such
maturity, yields for the two published maturities most closely corresponding to such
maturity shall be calculated pursuant to the immediately preceding sentence and the
Reinvestment Rate shall be interpolated or extrapolated from such yields on a
straight-line basis, rounding in each of such 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 Make-Whole Amount shall be used. If
the format or content of the Statistical Release changes in a manner that precludes
determination of the Treasury yield in the above manner, then the Treasury yield shall be
determined in the manner that most closely approximates the above manner, as reasonably
determined by the Company. 

-2- 

        “Statistical
Release” means the statistical release designated “H.15(519)” or any
successor publication which is published weekly by the Federal Reserve System and which
reports yields on actively traded United States government securities adjusted to constant
maturities, or, if such statistical release is not published at the time of any required
determination under the Indenture, then such other reasonably comparable index which shall
be designated by the Company. 

    10.                     The
Debentures shall not be subject to any sinking fund and shall not be
          repurchasable or redeemable at the option of a Holder.  

    11.                     The
Debentures shall not be convertible into other securities of the Company or
          exchangeable for securities of another issuer.  

    12.                     Satisfaction
and discharge under Section 701 of the Indenture shall be           applicable to the
Debentures; provided, however, that prior to any such           satisfaction and
discharge, the Company shall have delivered to the Trustee an           Opinion of
Counsel stating that (a) the Company has received from the Internal           Revenue
Service a letter ruling, or there has been published by the Internal           Revenue
Service a revenue ruling, or (b) since the date of execution of this           Officer’s
Certificate, there has been a change in the applicable Federal           income tax law,
in either case to the effect that, and based thereon such           opinion shall confirm
that, the Holders of such Outstanding Securities will not           recognize income,
gain or loss for Federal income tax purposes as a result of           such satisfaction
and discharge and will be subject to Federal income tax on the           same amounts, in
the same manner and at the same times as would have been the           case if such
satisfaction and discharge had not occurred.  

    13.                     The
Debentures shall initially be issued in whole in the form of one or more
          permanent global Securities. The Depository Trust Company (“DTC”), a
          clearing agency registered under the Securities Exchange Act of 1934, as
          amended, shall initially serve as the depositary for such global Security or
          Securities. For so long as DTC shall be the depositary, all Debentures shall be
          registered in its name or in the name of a nominee thereof. While the
Debentures           are evidenced by one or more global Securities, the depositary or
its nominee,           as the case may be, shall be the sole Holder thereof for all
purposes under the           Indenture. Neither the Company nor the Trustee shall have
any responsibility or           obligation to the depositary’s participants or the
beneficial owners for           whom they act with respect to their receipt from the
depositary of payments on           the Debentures or notices given under the Indenture.
The global Security or           Securities provided for hereunder shall bear such legend
or legends as may be           required from time to time by the depositary.  

    14.                     Except
as herein described, Debentures in definitive form will not be issued.
          Notwithstanding the foregoing, in the event the Company decides to discontinue
          the use of global Securities, any Event of Default has occurred and is
          continuing or DTC is at any time unwilling, unable or ineligible to continue as
          depositary and a successor depositary is not appointed by the Company within 90
          days, the Company shall issue individual Debentures in certificated form to
          owners of “book-entry” ownership interests in exchange for the
          Debentures held by DTC or its nominee, as the case may be. In such instance, an
          owner of a “book-entry” ownership interest will be entitled to
          physical delivery of certificates equal in principal amount to such
          “book-entry” ownership interest and to have such certificates
          registered in its name. Individual certificates so issued will be issued in
          denominations of $1,000 or any multiple thereof.  

-3- 

    15.                     Additional
terms regarding the Debentures are as set forth in the form of the           Debentures
set forth below.  

    16.                     The
form of the Debentures shall be substantially as follows:  

-4- 

        Unless
this certificate is presented by an authorized representative of The Depository Trust
Company, a New York corporation (“DTC”), to the Company (as defined below) 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.

        INTERSTATE
POWER AND LIGHT COMPANY, a corporation duly organized and existing under the laws of the
State of Iowa (herein called the “Company,” which term includes any successor
Person under the Indenture hereinafter referred to), for value received, hereby promises
to pay to Cede & Co., or registered assigns, the principal sum of
________________________ ($__________) on May 1, 2034 and to pay interest on said
principal sum from May 6, 2004, or from and including the most recent interest payment
date to which interest has been paid or duly provided for, semi-annually, in arrears, on
May 1 and November 1 of each year (each such date, an “Interest Payment Date”),
commencing November 1, 2004 at the rate of 6.30% per annum to, but not including, the
date on which the principal hereof is paid or made available for payment. The amount of
interest payable for any period will be computed on the basis of twelve 30-day months and
a 360-day year. The interest so payable, and punctually paid or duly provided for, on any
Interest Payment Date will, as provided in the Indenture, be paid to the Person in whose
name this Debenture (or one or more Predecessor Securities, as defined in the Indenture)
is registered at the close of business, on the Regular Record Date for such interest,
which shall be (1) the Business Day next preceding each such Interest Payment Date, if the
Debentures remain in book-entry only form, or (2) on the fifteenth calendar day before
each interest payment date, if the Debentures do not remain in book-entry only form. Any
such interest installment not so punctually paid or duly provided for shall forthwith
cease to be payable to the registered Holder on such Regular Record Date and may either be
paid to the Person in whose name this Debenture (or one or more Predecessor Securities) is
registered at the close of business on a Special Record Date for the payment of such
Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of
Debentures not later than 10 days prior to such Special Record Date, or be paid at any
time in any other lawful manner not inconsistent with the requirements of any securities
exchange on which the Debenture may be listed, or any book-entry system which may be
applicable to this Debenture and upon such notice as may be required by such exchange or
system, all as more fully provided in the Indenture. 

        Payment
of the principal of and interest on any Debenture that is not a global Debenture will be
made at the office or agency of the Company maintained for that purpose in The City of New
York; provided, however, that at the option of the Company payment of interest may be made
(i) by check mailed to the address of the Person entitled thereto as such address shall
appear in the Security Register or (ii) by wire transfer in immediately available funds at
such place and to such account as may be designated by the Person entitled thereto as
specified in the Security Register. Payment of principal of and interest on any global
Debenture will be made to DTC or its nominee, as the case may be, as the sole registered
owner and the sole Holder of the global Debenture for all purposes under the Indenture.
Payment of the principal of and interest on this Debenture will be made in such coin or
currency of the United States of America as at the time of payment is legal tender for
payment of public and private debts. 

        Additional
provisions of this Debenture are continued on the two pages following the execution and
authentication of this Debenture and such provisions have the same effect as though fully
set forth in this place. 

        Unless
the certificate of authentication hereon has been executed by or on behalf of the Trustee
by manual signature, this Debenture shall not be entitled to any benefit under the
Indenture or be valid or obligatory for any purpose.

INTERSTATE POWER AND
LIGHT COMPANY
6.30% SENIOR DEBENTURES DUE 2034  

        This
Debenture is one of a duly authorized issue of Debentures of the Company, designated as
its “6.30% Senior Debentures due 2034” (herein called the
“Debentures”), in aggregate principal amount of $100,000,000, issued under an
Indenture, dated as of August 20, 2003 (herein call the “Indenture”), between
the Company and J.P. Morgan Trust Company, National Association, successor, as Trustee
(the “Trustee”), to which Indenture and the Officer’s Certificate, dated
May 3, 2004, setting forth the terms and conditions of the Debentures, reference is hereby
made for a statement of the respective rights, limitations of rights, duties and
immunities thereunder of the Trustee, the Company and the Holders of the Debentures, and
of the terms upon which the Debenture are, and are to be, authenticated and delivered. 

        The
Company may redeem the Debentures at any time at the Company’s option, in whole or in
part, at a redemption price equal to the sum of the principal amount of the Debentures the
Company redeems, accrued interest on that principal amount to the redemption date and the
Make-Whole Amount (as defined in the Officer’s Certificate), if any, with respect to
those Debentures. 

        If
an Event of Default with respect to the Debentures shall occur and be continuing, the
principal of the Debentures may be declared due and payable in the manner, with the effect
and subject to the conditions, provided in the Indenture. 

        The
Indenture contains provisions for satisfaction and discharge at any time of the entire
indebtedness of this Debenture upon compliance by the Company with certain conditions set
forth in the Indenture. 

        The
Indenture contains provisions permitting the Company and the Trustee, with the consent of
the Holders of not less than a majority in principal amount of the Outstanding Debentures,
to modify the Indenture in a manner affecting the rights of the Holders of the Debentures;
provided that no such modification may, without the consent of the Holder of each
Outstanding Debenture, (i) change the Stated Maturity of, the principal of, or any
installment of principal of or interest on (except as provided in Section 312 of the
Indenture), any 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 change
the coin or currency (or other property), in which the Debentures 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 Debenture or (ii) reduce the
percentage in principal amount of the Outstanding Debentures of any series or any Tranche
thereof, the consent of the Holders of which is required for any such modification of the
Indenture. The Indenture also contains provisions permitting Holders of specified
percentages in principal amount of the Debentures at the time Outstanding, on behalf of
the Holders of all Debentures, to waive compliance by the Company with certain provisions
of the Indenture and certain past defaults under the Indenture and their consequences. Any
such consent or waiver by the Holder of this Debenture shall be conclusive and binding
upon such Holder and upon all future Holders of this Debenture and of any Debenture issued
upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether
or not notation of such consent or waiver is made upon this Debenture. 

        No
reference herein to the Indenture and no provision of this Debenture or of the Indenture
shall alter or impair the obligation of the Company, which is absolute and unconditional,
to pay the principal of and interest on this Debenture at the times, place and rate, and
in the coin or currency, herein prescribed. 

        As
provided in the Indenture and subject to certain limitations, including, if this Debenture
is a global Debenture, the limitations set forth on the first page hereof, therein set
forth, the transfer of this Debenture is registrable in the Security Register, upon
surrender of this Debenture for registration of transfer at the office or agency of the
Company in The City of New York maintained for such purpose, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the Company and
the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized
in writing, and thereupon one or more new Debentures, of authorized denominations and for
the same aggregate principal amount, will be issued to the designated transferee or
transferees. No service charge shall be made for any such registration of transfer or
exchange, but the Company may require payment of a sum sufficient to cover any tax or
other governmental charge payable in connection therewith. 

        Prior
to due presentment of this Debenture for registration of transfer, the Company, the
Trustee and any agent of the Trustee may treat the Person in whose name this Debenture is
registered as the owner hereof for all purposes, whether or not this Debenture be overdue,
