         Kirby Corporation, a Nevada corporation ("Issuer" or the "Company,"
which terms include any successor corporation under the Indenture hereinafter
referred to), for value received, hereby promises to pay to CEDE & CO., or
registered assigns, the principal sum of ____________________________________
DOLLARS, or if this is an Indexed Note, the principal amount as determined in
accordance with the terms set forth under "Other Provisions" above and/or in
the Addendum attached hereto, on the Stated Maturity Date specified above
(except to the extent redeemed or repaid prior to the Stated Maturity Date),
and to pay interest on the principal or face amount as set forth above at the
Interest Rate per annum specified above, until the principal hereof is paid or
duly made available for payment.  Reference herein to "this Note", "hereof",
"herein" and comparable terms shall include an Addendum hereto if an Addendum
is specified above.

         The Company will pay interest on each Interest Payment Date specified
above, commencing on the first Interest Payment Date next succeeding the
Original Issue Date specified above, and on the Stated Maturity Date or any
Redemption Date or Optional Repayment Date (if specified as repayable at the
option of the Holder in an attached Addendum) (the date of each such Stated
Maturity Date, Redemption Date and Optional Repayment Date and the date on
which principal or an installment of principal is due and payable by
declaration of acceleration pursuant to the Indenture being referred to
hereinafter as a "Maturity" with respect to principal payable on such date);
provided, however, that if the Original Issue Date is between a Regular Record
Date (as defined below) and the next succeeding Interest Payment Date, interest
payments will commence on the Interest Payment Date immediately following the
next succeeding Regular Record Date.  Except as provided above, interest
payments will be made on the Interest Payment Dates shown above.  Unless
otherwise specified above, the "Regular Record Date" shall be the date 15
calendar days (whether or not a Business Day) prior to the applicable Interest
Payment Date.  Interest on this Note will accrue from and including the most
recent Interest Payment Date to which interest has been paid or duly provided
for or, if no interest has been paid, from the Original Issue Date specified
above, to, but excluding such Interest Payment Date.  If the Maturity or an
Interest Payment Date falls on a day which is not a Business Day as defined
below, the payment due on such Maturity or Interest Payment Date will be paid
on the next succeeding Business Day with the same force and effect as if made
on such Maturity or Interest Payment Date, as the case may be, and no interest
shall accrue with respect to such payment for the period from and after such
Maturity or Interest Payment Date.  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 Note (or one or more
Predecessor Securities) is registered at the close of business on the Regular
Record Date for such Interest Payment Date.  Any such interest which is
payable, but not punctually paid or duly provided for on any Interest Payment
Date (herein called "Defaulted Interest"), shall forthwith cease to be payable
to the registered Holder on such Regular Record Date, and may be paid to the
Person in whose name this Note (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 Paying Agent, notice whereof shall be
given to the Holder of this Note not less than 10 days prior to such Special
Record Date, or may be paid at any time in any other lawful manner, all as more
fully provided in the Indenture.

         Payment of the principal of and interest on this Note will be made at
the office or agency of the Company 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 Security Register; and provided, further, that upon the
request of the Holder hereof, if the principal amount of this Note is
$10,000,000 or more, such Holder will be entitled to receive interest payments
by wire transfer of immediately available funds if appropriate wire transfer
instructions have been received in writing by the office or agency of the
Company maintained by the Company for such purpose not less than 15 days prior
to such Interest Payment Date.

benefit under the Indenture or be valid or obligatory for any purpose.

Trustee and the Holders of the Notes and the terms upon which the Notes are 
to be authenticated and delivered.  The terms of individual Notes may vary with
respect to interest rates or interest rate formulas, issue dates, maturity,
redemption, repayment, currency of payment and otherwise.

issued in global form only registered in the name of The Depository Trust
Company (the "Depositary") or its nominee.  The Notes will not be issued in
definitive form, except as otherwise provided in the Indenture, and ownership
of the Notes shall be maintained in book entry form by the Depositary for the
accounts of participating organizations of the Depositary.

         This Note is not subject to any sinking fund and, unless otherwise
provided above in accordance with the provisions of the following paragraphs,
is not redeemable or repayable prior to the Stated Maturity Date.

         If so provided above,this Note may be redeemed by the Company on any
date on and after the Initial Redemption Date, if any, specified above.  If no
Initial Redemption Date is set forth above, this Note may not be redeemed prior
to the Stated Maturity Date.  On and after the Initial Redemption Date, if any,
this Note may be redeemed at any time in whole or from time to time in part in
increments of $1,000 (provided that any remaining principal hereof shall be at
least $1,000) at the option of the Company at the applicable Redemption Price
(as defined below), together with accrued interest hereon at the applicable
rate payable to the date of redemption (each such date, a "Redemption Date"),

                                       4
   5
more than 60 nor less than 30 days prior to the Redemption Date.  In the event
of redemption of this Note in part only, a new Note for the unredeemed portion
hereof shall be issued in the name of the Holder hereof upon the surrender
hereof.

         Unless otherwise specified above, the "Redemption Price" shall
initially be the Initial Redemption Percentage, specified above, of the
principal amount of this Note to be redeemed and shall decline at each
anniversary of the Initial Redemption Date, shown above, by the Annual
Redemption Percentage Reduction, if any, specified above hereof, of the
principal amount to be redeemed until the Redemption Price is 100% of such
principal amount.

         Unless otherwise specified in an Addendum attached hereto, this Note
is not subject to repayment at the option of the Holder.  If this Note shall be
repayable at the option of the Holder as specified in an attached Addendum
hereto, unless otherwise specified in such Addendum, on any Optional Repayment
Date, this Note shall be repayable in whole or in part in increments of $1,000
(provided that any remaining principal hereof shall be at least $1,000) at the
option of the Holder hereof at a repayment price equal to 100% of the principal
amount to be repaid, together with interest thereon payable to the date of
repayment.  If specified as repayable at the option of the Holder in such
Addendum, for this Note to be repaid in whole or in part at the option of the
Holder hereof, this Note must be received, with the form entitled "Option to
Elect Repayment" below duly completed, by the Paying Agent at its principal
office, or such address which the Company shall from time to time notify the
Holders of the Notes, not more than 60 nor less than 30 days prior to the
related Optional Repayment Date.  Exercise of such repayment option by the
Holder hereof shall be irrevocable.

         Unless otherwise specified above, the "Interest Payment Dates" for the
Fixed Rate Notes will be April 15 and October 15 of each year and the Maturity
Date.  Unless otherwise specified above, interest on Fixed Rate Notes will be
computed on the basis of a 360-day year of twelve 30-day months.

         If any Interest Payment Date or the Maturity Date of a Fixed Rate Note
falls on a day that is not a Business Day, the required payment of principal,
premium, if any, and/or interest will be made on the next succeeding Business
Day as if made on the date such payment was due, and no interest will accrue on
such payment for the period from and after such Interest Payment Date or the
Maturity Date, as the case may be, to the date of such payment on the next
succeeding Business Day.

         As used herein, "Business Day" means any day other than a Saturday or
Sunday or any other day on which banks in The City of New York are generally
authorized or obligated by law or executive order to close.

         Notwithstanding anything to the contrary contained herein or in the
Indenture, for purposes of determining the rights of a Holder of a Note for
which the principal thereof is determined by reference to the price or prices
of specified commodities or stocks, interest rate indices, interest or exchange
rate swap indices, the exchange rate of one or more





                                       5
   6
specified currencies (including a composite currency such as the European
Currency Unit) relative to an indexed currency or such other price, exchange
rate or other financial index or indices as specified above (an "Indexed
Note"), in respect of voting for or against amendments to the Indenture and
modifications and the waiver of rights thereunder, the principal amount of any
such Indexed Note shall be deemed to be equal to the face amount thereof upon
issuance.  The method for determining the amount of principal payable at
Maturity on an Indexed Note will be specified in an attached Addendum.

         Any provision contained herein with respect to the calculation of the
rate of interest applicable to this Note, its payment dates or any other matter
relating hereto may be modified as specified in an Addendum relating hereto if
so specified above, and references herein to "as specified above" or similar
language of like import shall also be references to any such Addendum.

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

         The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected thereby at any time by the Company and the Trustee with the consent of
the a majority of the Holders of the aggregate principal amount of the
Outstanding Securities of each series affected thereby.  The Indenture also
contains provisions permitting the Holders of a majority in aggregate principal
amount of the  Securities of each series at the time Outstanding, on behalf of
the Holders of all the Securities of such series, 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 interest on this Note
at the time, place and rate, and in the coin or currency, herein prescribed.

         As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this Note may be registered on the Security
Register of the Company, upon surrender of this Note for registration of
transfer at the office or agency of the Company in the Borough of Manhattan,
The City of New York, 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 by its attorney duly authorized in writing,
and thereupon one or more new Notes of authorized denominations and for the
same aggregate principal amount, will be issued to the designated transferee or
transferees.

         The Notes are issuable only in registered form without coupons in
denominations of $1,000 and integral multiples thereof.  As provided in the
Indenture and subject to certain limitations therein set forth, the Notes are
exchangeable for a like aggregate principal amount of Notes 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.

         Prior to due presentment of this Note for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name this Note is registered as the owner hereof for all
purposes, whether or not this Note be overdue, and neither the Company, the

accordance with the laws of the State of New York.
