                      6.20% Senior Notes due April 1, 2033

1.   Interest.

     Wisconsin Energy Corporation (the "Company"), a Wisconsin corporation,
     promises to pay interest on the principal amount of this Security at the
     rate per annum shown above. The Company will pay interest semiannually on
     April 1 and October 1 of each year commencing October 1, 2003. Interest on
     the Securities will accrue from the most recent date to which interest has
     been paid or, if no interest has been paid, from March 20, 2003. Interest
     will be computed on the basis of a 360-day year of twelve 30-day months.

2.   Method of Payment.

     The Company will pay interest on the Securities to the persons who are
     registered holders of Securities at the close of business on the record
     date for the next interest payment date, except as otherwise provided in
     the Indenture. Holders must surrender Securities to a Paying Agent to
     collect principal payments. The Company will pay principal and interest in
     money of the United States that at the time of payment is legal tender for
     payment of public and private debts. The Company may pay principal and
     interest by check payable in such money. It may mail an interest check to a
     holder's registered address.

3.   Securities Agents.

     Initially, Bank One Trust Company, National Association (successor to The
     First National Bank of Chicago) will act as Paying Agent, Transfer Agent
     and Registrar. The Company may change any Paying Agent or Transfer Agent
     without notice. The Company or any Affiliate may act in any such capacity.
     Subject to certain conditions, the Company may change the Trustee.

4.   Indenture.

     The Company issued the securities of this series (the "Securities") under
     an Indenture dated as of March 15, 1999 (the "Indenture") between the
     Company and Bank One Trust Company, National Association (successor to The
     First National Bank of Chicago) (the "Trustee"). The terms of the
     Securities include those stated in the Indenture and in the Securities
     Resolution establishing the Securities and those made part of the Indenture
     by the Trust Indenture Act of 1939 (15 U.S. Code Sections

                                      -2-

<PAGE>

     77aaa-77bbbb). Securityholders are referred to the Indenture, the
     Securities Resolution and such Act for a statement of such terms.

5.   Redemption.

     The Securities will be redeemable as a whole at any time, or in part from
time to time, at the Company's option, at a redemption price equal to the
greater of (a) 100% of the principal amount of the Securities being redeemed or
(b) the sum of the present values of the remaining scheduled payments of
principal and interest thereon (exclusive of interest accrued to the date of
redemption) discounted to the redemption date on a semiannual basis (assuming a
360-day year consisting of twelve 30-day months) at the Treasury Rate applicable
to the Securities plus 25 basis points, plus accrued interest to the redemption
date.

     "Treasury Rate" means with respect to any redemption date, the rate per
annum equal to the semiannual equivalent yield to maturity or interpolated (on a
day count basis) of the Comparable Treasury Issue, assuming a price for the
Comparable Treasury Issue (expressed as a percentage of its principal amount)
equal to the Comparable Treasury Price for such redemption date; provided that,
if the Reference Treasury Dealers shall determine that there is no such
Comparable Treasury Issue, such rate per year shall be equal to the estimated
semiannual equivalent yield to maturity that a United States Treasury security
having a maturity comparable to the remaining term of the Securities would bear,
if such security were available, such estimate to be made by the Reference
Treasury Dealers on the basis of interpolation, extrapolation and other accepted
financial practices, taking into account (a) the yields to maturity of United
States Treasury securities of other maturities, (b) yields to maturity of other
U.S. dollar denominated debt securities having a maturity comparable to the
remaining term of the Securities to be redeemed and (c) applicable interest rate
spreads between United States Treasury securities and such other debt
securities, all as of 5:00 p.m., New York City time, on the third business day
preceding such redemption date.

     "Comparable Treasury Issue" means the United States Treasury security or
securities selected by an Independent Investment Banker as having an actual or
interpolated maturity comparable to the remaining term of the Securities being
redeemed that would be utilized, at the time of selection and in accordance with
customary financial practice, in pricing new issues of corporate debt securities
of a comparable maturity to the remaining term of such Securities.

     "Independent Investment Banker" means one of the Reference Treasury Dealers
appointed by the Trustee after consultation with the Company.

     "Comparable Treasury Price" means, with respect to any redemption date, (a)
the average of the Reference Treasury Dealer Quotations for such redemption
date, after

                                      -3-

<PAGE>

excluding the highest and lowest such Reference Treasury Dealer Quotations, or
(b) if the Trustee obtains fewer than four such Reference Treasury Dealer
Quotations, the average of all such quotations.

     "Reference Treasury Dealer Quotations" means, with respect to each
Reference Treasury Dealer and any redemption date, the average, as determined by
the Trustee, of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) quoted in
writing to the Trustee by such Reference Treasury Dealer at 3:30 p.m. New York
time on the third business day preceding such redemption date.

     "Reference Treasury Dealer" means each of Salomon Smith Barney Inc. and
three other primary U.S. Government securities dealers in The City of New York
(a "Primary Treasury Dealer"), selected by the Company. If any Reference
Treasury Dealer shall cease to be a Primary Treasury Dealer, the Company will
substitute another Primary Treasury Dealer for that dealer.

     Procedures for redemption of the Securities will be governed by Article III
of the Indenture.

6.   Denominations, Transfer, Exchange.

     The Securities are in registered form without coupons in denominations of
     $1,000 and whole multiples of $1,000. The transfer of Securities may be
     registered and Securities may be exchanged as provided in the Indenture.
     The Transfer Agent may require a holder, among other things, to furnish
     appropriate endorsements and transfer documents and to pay any taxes and
     fees required by law or the Indenture. The Transfer Agent need not exchange
     or register the transfer of any Security or portion of a Security selected
     for redemption. Also, it need not exchange or register the transfer of any
     Securities for a period of 15 days before a selection of Securities to be
     redeemed.

7.   Persons Deemed Owners.

     The registered holder of a Security may be treated as its owner for all
     purposes.

8.   Amendments and Waivers.

     Subject to certain exceptions, the Indenture or the Securities may be
     amended with the consent of the holders of a majority in principal amount
     of the securities of all series affected by the amendment. Subject to
     certain exceptions, a default on a series may be waived with the consent of
     the holders of a majority in principal amount of the series.

                                      -4-

<PAGE>

     Without the consent of any Securityholder, the Indenture or the Securities
     may be amended, among other things, to cure any ambiguity, omission, defect
     or inconsistency; to provide for assumption of Company obligations to
     Securityholders; or to make any change that does not materially adversely
     affect the rights of any Securityholder.

9.   Restrictive Covenants.

     The Securities are unsecured general obligations of the Company initially
     limited to $200,000,000 principal amount. The Company may from time to time
     without notice to, or the consent of, the holders of the Securities create
     and issue further securities, equal in rank, of the same series and having
     the same terms (except for the payment of interest accruing prior to the
     issue date of the new securities or except for the first payment of
     interest following the issue date of the new securities) so that the new
     securities may be consolidated and form a single series with the Securities
     and have the same terms as to status, redemption or otherwise as the
     Securities. The Indenture does not limit other unsecured debt.

     In addition to the restrictions on the Securities contained in the
     Indenture, the Securities will be subject to the following additional
     restrictive covenant:

     Limitation upon Liens on Stock of Certain Subsidiaries

     For so long as any Securities remain outstanding, the Company will not
     create or incur or allow any of its subsidiaries to create or incur any
     pledge or security interest on any of the capital stock of Wisconsin
     Electric Power Company ("Wisconsin Electric") or Wisconsin Gas Company
     ("Wisconsin Gas") held by the Company or one of the Company's subsidiaries
     on the issue date of the Securities.

10.  Successors.

     When a successor assumes all the obligations of the Company under the
     Securities and the Indenture, the Company will be released from those
     obligations.

11.  Defeasance Prior to Redemption or Maturity.

     Subject to certain conditions, the Company at any time may terminate some
     or all of its obligations under the Securities and the Indenture if the
     Company deposits with the Trustee money or U.S. Government Obligations for
     the payment of principal and interest on the Securities to redemption or
     maturity. U.S. Government Obligations are securities backed by the full
     faith and credit of the United States of America or certificates
     representing an ownership interest in such Obligations.

12.  Defaults and Remedies.

     An Event of Default includes: default for 60 days in payment of interest on
     the Securities; default in payment of principal on the Securities; default
     for 60 days in the payment of any sinking fund obligation; default by the
     Company for a specified period after notice to it in the performance of any
     of its other agreements applicable to the Securities; certain events of
     bankruptcy or insolvency; and any other Event of Default provided for in
     the series. If an Event of Default occurs and is continuing, the Trustee or
     the holders of at least 25% in principal amount of the Securities may
     declare the principal of all the Securities to be due and payable
     immediately.

     In addition, an Event of Default under the Securities shall also include a
     failure to pay when due principal, interest or premium in an aggregate
     amount of $25 million or more with respect to any Indebtedness (as defined
     below) of the Company or its principal utility subsidiaries, Wisconsin
     Electric and Wisconsin Gas, or the acceleration of any such Indebtedness
     aggregating $25 million or more which default shall not be cured, waived or
     postponed pursuant to an agreement with the holders of such Indebtedness
     within 60 days after written notice as provided in the Indenture, or such
     acceleration shall not be rescinded or annulled within 30 days after
     written notice as provided in the Indenture. As used herein, "Indebtedness"
     means the following obligations of the Company, Wisconsin Electric and
     Wisconsin Gas (and specifically excludes obligations of the Company's other
     subsidiaries and intercompany obligations): (a) all obligations for
     borrowed money, (b) all obligations evidenced by bonds, debentures, notes
     or similar instruments, or upon which interest payments are customarily
     made, (c) all obligations under conditional sale or other title retention
     agreements relating to property purchased, to the extent of the value of
     such property (other than customary reservations or retentions of title
     under agreements with suppliers entered into in the ordinary course of
     business), and (d) all obligations, other than intercompany items, issued
     or assumed as the deferred purchase price of property or services purchased
     which would appear as liabilities on a balance sheet of the Company,
     Wisconsin Electric or Wisconsin Gas.

     Securityholders may not enforce the Indenture or the Securities except as
     provided in the Indenture. The Trustee may require indemnity satisfactory
     to it before it enforces the Indenture or the Securities. Subject to
     certain limitations, holders of a majority in principal amount of the
     Securities may direct the Trustee in its exercise of any trust or power.
     The Trustee may withhold from Securityholders notice of any continuing
     default (except a default in payment of principal or interest) if it
     determines that withholding notice is in their interests. The Company must
     furnish an annual compliance certificate to the Trustee.

                                      -6-

13.  Trustee Dealings with Company.

     Bank One Trust Company, National Association (successor to The First
     National Bank of Chicago), the Trustee under the Indenture, in its
     individual or any other capacity, may make loans to, accept deposits from,
     and perform services for the Company or its Affiliates, and may otherwise
     deal with those persons, as if it were not Trustee.

14.  No Recourse Against Others.

     A director, officer, employee or stockholder, as such, of the Company shall
     not have any liability for any obligations of the Company under the
     Securities or the Indenture or for any claim based on, in respect of or by
     reason of such obligations or their creation. Each Securityholder by
     accepting a Security waives and releases all such liability. The waiver and
     release are part of the consideration for the issue of the Securities.

15.  Authentication.

     This Security shall not be valid until authenticated by a manual signature
     of the Registrar.

16.  Abbreviations.

     Customary abbreviations may be used in the name of a Securityholder or an
     assignee, such as: TEN COM (=tenants in common), TEN ENT (=tenants by the
     entirety), JT TEN (=joint tenants with right of survivorship and not as
     tenants in common), CUST (=custodian), U/G/M/A (=Uniform Gifts to Minors
     Act), and U/T/M/A (=Uniform Transfers to Minors Act).

                                   6.20% Notes

                               Supplemental Terms

     In addition to the terms set forth in Exhibit 1 to Securities Resolution
No. 4, the 6.20% Notes shall have the following terms:

     Section 1. Definitions. Capitalized terms used and not defined herein shall
have the meaning given such terms in the Indenture. The following is an
additional definition applicable to the 6.20% Notes:

     "Depositary" means, with respect to the 6.20% Notes, issued as one or more
     global Securities, The Depository Trust Company, New York, New York, or any
     successor thereto registered under the Securities Exchange Act of 1934 or
     other applicable statute or regulation.

     Section 2. Securities Issuable as Global Securities.

     (a) The 6.20% Notes shall each be issued in the form of one or more
permanent global Securities and shall, except as otherwise provided in this
Section 2, be registered only in the name of the Depositary or its nominee. Each
global Security shall bear a legend substantially to the following effect:

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

     (b) If at any time (i) the Depositary with respect to the 6.20% Notes
notifies the Company that it is unwilling or unable to continue as Depositary
for such global Security or (ii) the Depositary for the 6.20% Notes shall no
longer be eligible or in good standing under

<PAGE>

the Securities Exchange Act of 1934 or other applicable statute or regulation,
the Company shall appoint a successor Depositary with respect to such global
Security. If a successor Depositary for such global Security is not appointed by
the Company within 90 days after the Company receives such notice or becomes
aware of such ineligibility, the Transfer Agent shall register the exchange of
such global Security for an equal principal amount of Registered Securities in
the manner provided in Section 2.07 of the Indenture.

     (c) The Transfer Agent shall register the transfer or exchange of a global
Security for Registered Securities pursuant to Section 2.07 of the Indenture if
(i) a Default or Event of Default shall have occurred and be continuing with
respect to the 6.20% Notes or (ii) the Company determines that the 6.20% Notes
shall no longer be represented by global Securities.

     (d) In any exchange provided for in the preceding paragraphs (b) or (c),
the Company will execute and the Registrar will authenticate and deliver
Registered Securities. Registered Securities issued in exchange for a global
Security shall be in such names and denominations as the Depositary for such
global Security shall instruct the Registrar. The Registrar shall deliver such
Registered Securities to the persons in whose names such Securities are so
registered.

     (e) The 6.20% Notes will trade in the Depositary's Same-Day Funds
Settlement System. All payments of principal and interest on global Securities
will be made by the Company in immediately available funds.
