     McLeodUSA Incorporated, a corporation duly organized and existing under the
laws of Delaware (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
(which principal amount may from time to time be increased or decreased to such
other principal amounts (which, taken together with the principal amounts of all
other outstanding Notes, shall not exceed THREE HUNDRED MILLION DOLLARS
($300,000,000) in the aggregate at any time) by adjustments made on the records
of the Trustee hereinafter referred to in accordance with the Indenture) on
November 1, 2008, and to pay interest thereon from the Issue Date, semi-annually
in arrears on November 1 and May 1 of each year, commencing May 1, 1999, at the
rate of 9.5% per annum, until the principal hereof is paid or

 
made available for payment; PROVIDED, HOWEVER, that if (i) the Company has not
filed a registration statement (the "Exchange Offer Registration Statement")
under the Securities Act of 1933, as amended (the "Act"), registering a security
substantially identical to this Note (except that such Note will not contain
terms with respect to the Special Interest payments described below or transfer
restrictions) pursuant to an exchange offer (the "Registered Exchange Offer")
(or, in lieu thereof, a registration statement registering this Note for resale

Registered Exchange Offer has been consummated nor the Shelf Registration
Statement has been declared effective prior to April 28, 1999, or (iv) either
the Exchange Offer Registration Statement or, if applicable, the Shelf
Registration Statement is filed and declared effective (except as specifically
permitted therein) but shall thereafter cease to be effective without being
succeeded promptly by an additional registration statement filed and declared
effective, in each case (i) through (iv) upon the terms and conditions set forth
in the Registration Agreement (each such event referred to in clauses (i)
through (iv), a "Registration Default"), then interest will accrue (in addition
to any stated interest on the Notes) (the "Step-Up") at a rate of 0.5% per
annum, during the 90-day period from and including the date on which any such
Registration Default shall occur to but excluding the date on which all
Registration Defaults have been cured and shall increase by 0.25% per annum at
the end of each subsequent 90-day period, but in no event shall such rate exceed
2.00% per annum, in the aggregate regardless of the number of Registration

"Special Interest." Accrued Special Interest, if any, shall be paid semi-
annually on November 1 and May 1 of each year; and the amount of accrued Special
Interest shall be determined on the basis of the number of days actually
elapsed. Any accrued and unpaid interest (including Special Interest) on this
Note upon the issuance of an Exchange Note (as defined in the Indenture) in
exchange for this Note shall cease to be payable to the Holder hereof but such
accrued and unpaid interest (including Special Interest) shall be payable on the
next Interest Payment Date for such Exchange Note to the Holder thereof on the

duly provided for, on any Interest Payment Date will, as provided in such
Indenture, be paid to the Person in whose name this Note (or one or more
Predecessor Notes) is registered at the close of business on the Regular Record
Date for such interest, which shall be October 15 or April 15 (whether or not a
Business Day), as the case may be, immediately preceding such Interest Payment
Date. Any such interest not so punctually paid or duly provided for will
forthwith cease to be payable to the Holder on such Regular Record Date and may
either be paid to the Person in whose name this Note (or one or more Predecessor
Notes) 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 Notes not more than 15 calendar days and not less
than 10 calendar 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 Notes may be listed, and upon such notice as
may be required by such exchange, all as more fully provided in said Indenture.

     The principal of this Note shall accrue interest at the rate of 9.5% per
annum, and in the case of a default in payment of principal and premium, if any,
upon acceleration or redemption, in which case interest shall be payable
pursuant to the preceding paragraph on such overdue principal (and premium, if
any), such interest shall be payable on demand and, if not so paid on demand,
such interest shall itself bear interest at the rate of 10.5% per annum (to the
extent that the payment of such interest shall be legally enforceable), and
shall accrue from the date 

 
of such demand for payment to the date payment of such interest has been made or
duly provided for, and such interest on unpaid interest shall also be payable on
demand.

     Payment of the principal of (and premium, if any) and interest on this Note
will be made at the corporate trust office of the Trustee and at the office or
agency of the Company maintained for that purpose in the Borough of Manhattan,
The City of New York, New York, and at any other office or agency maintained by
the Company for such purpose, 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; PROVIDED, HOWEVER, that at the option of the Company payment of
interest may be made by check mailed to the address of the Person entitled
thereto as such address shall appear in the Note Register.

     Reference is hereby made to the further provisions of this Note set forth
on the reverse hereof, which further provisions shall for all purposes have the
same effect as if set forth at this place.

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

 
     IN WITNESS WHEREOF, the Company has caused this instrument to be duly
executed.

amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Notes under the Indenture at any
time by the Company and the Trustee with the consent of the Holders of a

percentages in aggregate principal amount of the Notes at the time outstanding,
on behalf of the Holders of all the Notes, 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 Note shall be conclusive and binding upon such Holder and upon all future
Holders of this Note and of any Note 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 Note.

     No reference herein to the Indenture and no provision of this Note or of
the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of (and premium, if any) and
interest on this Note at the times, place and rate, and in the coin or currency,

exchangeable for a like tenor and aggregate principal amount of Notes of a
different authorized denomination, as requested by the Holder surrendering the
same.

     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.

Trustee nor any such agent shall be affected by notice to the contrary.

twelve 30-day months; PROVIDED, HOWEVER, that Special Interest shall be computed
on the basis of a 365- or 366-day year, as the case may be, and the number of
days actually elapsed.

CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO
AGREEMENTS MADE AND TO BE PERFORMED IN SUCH STATE.
