     CASE CREDIT CORPORATION, a corporation duly organized and existing under
the laws of the State of Delaware (herein called the "Company", which term

value received, hereby promises to pay to Cede & Co., as nominee for DTC, or
registered assigns, the principal sum of One Hundred Million Dollars
($100,000,000) on October 15, 2001, and to pay interest thereon from October 27,
1998 or from the most recent Interest Payment Date to which interest has been
paid or duly provided for, semi-annually on April 15 and October 15 in each
year, commencing April 15, 1999, at the rate of 6 1/8% per annum, until the
principal hereof is paid or made available for payment. The interest so payable,
and punctually paid or duly provided for, on any Interest Payment Date will, as

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 Security (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 Securities of this series
not less than 10 days prior to such Special Record Date, or be paid at any time

Trustee referred to herein by manual signature, this Security shall not be
entitled to any benefit under the Indenture or be valid or obligatory for any
purpose.

Company (herein called the "Securities"), issued and to be issued in one or more
series under an Indenture, dated as of October 1, 1997 (herein called the

of the Securities of each series at the time Outstanding, on behalf of the
Holders of all Securities of such series, to waive compliance by the Company

this Security shall be conclusive and binding upon such Holder and upon all
future Holders of this Security and of any Security 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 Security.

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