                            CASE CREDIT CORPORATION

          CASE CREDIT CORPORATION, a corporation duly organized and existing
under the laws of the State 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., as nominee for DTC, or
registered assigns, the principal sum of One Hundred Fifty Million Dollars
($150,000,000) on October 21, 2007, and to pay interest thereon from October 21,
1997 or from the most recent Interest Payment Date to which interest has been
paid or duly provided for, semi-annually on April 21 and October 21 in each
year, commencing April 21, 1998, at the rate of 6:% 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
provided in such Indenture, be paid to the Person in whose name this Security
(or one or more Predecessor Securities) is registered at the close of business
on the Regular Record Date for such interest, which shall be April 7 or October
7 (whether or not a Business Day), as the case may be, next 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 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
in any other lawful manner not inconsistent with the requirements of any
securities exchange on which the Securities of this series may be listed, and
upon such notice as may be required by such exchange, all as more fully provided
in said Indenture.

          Payment of the principal (and premium, if any) and interest on this
Security will be made at the office or agency of the Company maintained for that
purpose in New York, New York, 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.

          Unless the certificate of authentication hereon has been executed by
the 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.

          This Security is one of a duly authorized issue of securities of the
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
"Indenture"), between the Company and The Bank of New York, as Trustee (herein
called the "Trustee", which term includes any successor trustee under the

Indenture), to which Indenture and all indentures supplemental thereto reference
is hereby made for a statement of the respective rights, limitations of rights,
duties and immunities thereunder of the Company, the Trustee and the Holders of
the Securities and of the terms upon which the Securities are, and are to be,
authenticated and delivered. This Security is one of the series designated on
the face hereof, limited in aggregate principal amount to $150,000,000.

          The Securities of this series will be redeemable in whole or in part
at any time at the option of the Company at a redemption price (the "Redemption
Price") equal to the greater of (i) 100% of the principal amount of such
Securities, plus accrued but unpaid interest thereon to the date of redemption
(the ARedemption Date@) and (ii) the sum of the present values of the remaining
scheduled payments of principal and interest thereon discounted to the
Redemption Date on a semi-annual basis (assuming a 360-day year consisting of
twelve 30-day months) at the Treasury Rate plus 15 basis points, plus accrued
but unpaid interest thereon to the Redemption Date.  If a Redemption Date does
not fall on an interest payment date, then, with respect to the interest payment
immediately succeeding the Redemption Date, only the unaccrued portion of such
interest payment as of the Redemption Date shall be included in any present
value calculation pursuant to clause (ii).

          "Treasury Rate" means, with respect to any Redemption Date, the rate
          per annum equal to the semi-annual equivalent yield to maturity of the

          equal to the Comparable Treasury Price for such Redemption Date.

          "Comparable Treasury Issue" means the United States Treasury security
          selected by an Independent Investment Banker as having a maturity
          comparable to the remaining term of the Securities of this series to
          be 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 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, (i) the average of the bid and asked prices for the Comparable
          Treasury Issue (expressed in each case as a percentage of its
          principal amount) on the third Business Day preceding such Redemption
          Date, as set forth in the daily statistical release (or any successor
          release) published by
<PAGE>
 
          the Federal Reserve Bank of New York and designated "Composite 3:30
          p.m. Quotations for U.S. Government Securities" or (ii) if such
          release (or any successor release) is not published or does not
          contain such prices on such Business Day, (a) the average of the
          Reference Treasury Dealer Quotations for such Redemption Date, after
          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
          Reference Treasury Dealer 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 5:00 p.m. on the
          third Business Day preceding such Redemption Date.

          "Reference Treasury Dealer" means each of Merrill Lynch, Pierce,
          Fenner & Smith Incorporated and NationsBanc Montgomery Securities,

          Dealer") selected by the Company pursuant to Section 3.1 of the
          Indenture in addition to, or in substitution for, any of such firms;
          provided, however, that if any of the foregoing shall cease to be a
          Primary Treasury Dealer, the Company shall substitute therefor another
          Primary Treasury Dealer.

          Notice of any redemption will be mailed at least 30 days but not more
than 60 days before the Redemption Date to each holder of the Securities of this
series to be redeemed.

          Unless the Company defaults in payment of the Redemption Price, on and
after the Redemption Date interest will cease to accrue on the Securities of
this series or portions thereof called for redemption.

          The Securities of this series shall not provide for a sinking fund.

          If an Event of Default with respect to Securities of this series shall

Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of a majority in principal amount of the Securities at
the time Outstanding of each series to be affected. The Indenture also contains
provisions permitting the Holders of specified percentages in principal amount
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
with certain provisions of the Indenture and certain past defaults under the

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

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

Securities of this series are exchangeable for a like aggregate principal amount
of Securities of this series and of like tenor 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 
<PAGE>
 
sufficient to cover any tax or other governmental charge payable in connection
therewith.

          Prior to due presentment of this Security for registration of
