                            INTERNATIONAL CORPORATION

                              6 1/4% Note due 2012

        This Note is one of a duly authorized issue of debentures, notes, bonds
or other evidences of indebtedness of the Issuer (hereinafter called the
"Securities") of the series hereinafter specified, all issued or to be issued
under and pursuant to an indenture dated as of June 28, 2002 (herein called the
"Indenture"), duly executed and delivered by the Issuer to JPMorgan Chase Bank,
as Trustee (herein called the "Trustee"), to which Indenture and all indentures
supplemental thereto reference is hereby made for a description of the rights,
limitation of rights, obligations, duties and immunities thereunder of the
Trustee, the Issuer and the holders of the Securities. The Securities may be
issued in one or more series, which different series may be issued in various
aggregate principal amounts, may mature at different times, may bear interest
(if any) at different rates, may be subject to different redemption provisions
(if any), may be subject to different sinking, purchase or analogous funds (if
any) and may otherwise vary as in the Indenture provided.

        The initial aggregate principal amount of the series of Securities of
which this Note forms a part is $550,000,000. The series of Securities of which
this Note forms a part may be reopened, without notice to or consent of the
holders of the Notes, for issuances of additional Notes of such series. The
additional Notes may be of the same tenor, interest rate and other terms as this
Note and this Note together with any such additional Notes may form a single
series. References herein to the Notes shall include (unless the context
otherwise requires) any further Notes issued as described in this paragraph.

        Interest will be computed on the basis of a 360-day year of twelve
30-day months. The Issuer shall pay interest on overdue principal and, to the
extent lawful, on overdue installments of interest at the rate pre annum borne
by this Note. If a payment date is not a Business Day, payment may be made at
the place of payment on the next succeeding day that is a Business Day, and no
interest shall accrue for the intervening period.

        In case an Event of Default, as defined in the Indenture, with respect
to the 6 1/4% Notes due 2012 shall have occurred and be continuing, the
principal hereof and the interest accrued hereon, if any, may be declared, and
upon such declaration shall become, due and payable, in the manner, with the
effect and subject to the conditions, provided in the Indenture.

        The Indenture contains provisions which permit the Issuer and the
Trustee, with the written consent of the Holders of not less than a majority in
aggregate principal amount of the Securities at the time Outstanding of each
series affected thereby (each such series voting as a separate class), to
supplement the Indenture or any supplemental

                                       4
<PAGE>

indenture or modify the rights of the holders of the Securities of such series;
provided, that no such supplemental indenture shall without the consent of the
holders of each Security so affected: (i) extend the stated maturity or reduce
the principal amount of any Security or any portion thereof, or reduce the rate
or extend the time of payment of interest thereon, or reduce any amount payable
on redemption thereof, or change the currency in which the Security is payable,
or reduce the amount of the principal of an Original Issue Discount Security
that would be due and payable upon an acceleration of the maturity thereof or
the amount thereof provable in bankruptcy, or impair or affect the right of any
holder of Securities to institute suit for the payment thereof or (ii) reduce
the aforesaid percentage of Securities of any series, the consent of the Holders
of which is required for any such supplemental indenture, or (iii) modify any
provisions of Sections 8.02 or 5.10 of the Indenture except to increase any such
percentage referred to in such provision or to provide that certain other
provisions of the Indenture cannot be modified or waived without the consent of
the holders of each Security so affected.

        It is also provided in the Indenture that an existing default or Event
of Default with respect to the Securities of any series, and its consequences,
may be waived in the manner and subject to the conditions set forth in the
Indenture, except a default in the payment of principal of or interest on any
Security or in respect of a covenant or provision of the Indenture which cannot
be modified or amended without the consent of the holder of each Outstanding
Security affected. Upon any such waiver, such default shall cease to exist and
be deemed to have been cured and not to have occurred, and any Event of Default
arising therefrom shall be deemed to have been cured and not to have occurred,
for every purpose of the Indenture; but no such waiver shall extend to any
subsequent or other default or Event of Default or impair any right consequent
thereto.

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

        The Notes are issuable initially only in registered form without coupons
in denominations of $1,000 or any integral multiple thereof and in the manner
and subject to the limitations provided in the Indenture.

        This Note is redeemable, in whole or in part, prior to maturity at the
option of the Issuer at any time or from time to time at a redemption price
equal to the greater of (i) 100% of the aggregate principal amount of the Notes
to be redeemed and (ii) as determined by an Independent Investment Banker, the
sum of the present values of the remaining scheduled payments of principal and
interest thereon (not including any portion of such payments of interest accrued
as of the date of redemption) discounted to the date of redemption on a
semi-annual basis (assuming a 360-day year consisting of twelve 30-day months)
at the Adjusted Treasury Rate (as defined below) plus 25 basis points, plus, in
each case, accrued and unpaid interest thereon to the date of redemption.

                                       5
<PAGE>

        "Adjusted Treasury Rate" means, with respect to any redemption date, the
rate per annum equal to the semi-annual equivalent yield to maturity (computed
as of the third Business Day immediately preceding the redemption date) 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, calculated in accordance with standard
market practice.

         "Comparable Treasury Issue" means the United States Treasury security
selected by an Independent Investment Banker that would be used, 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 Notes.

        "Comparable Treasury Price" means, with respect to any redemption date,
either (i) the average of the Reference Treasury Dealer Quotations for such
redemption date, after excluding the highest and lowest such Reference Treasury
Dealer Quotations, or (ii) if the Trustee obtains fewer than three such
Reference Treasury Dealer Quotations, the average of all such Reference Treasury
Dealer Quotations obtained.

        "Independent Investment Banker" means one of the Reference Treasury
Dealers appointed by the Issuer.

        "Reference Treasury Dealer" means each of J.P. Morgan Securities Inc.
(and its successors), and any other nationally recognized investment banking
firm that is a primary U.S. Government securities dealer specified from time to
time by the Issuer. If, however, any of them ceases to be a primary U.S.
Government securities dealer, the Issuer shall substitute another nationally
recognized investment banking firm that is such a dealer.

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

        If less than all of the Notes are to be redeemed at any time, the
Trustee shall select the Notes to be redeemed in compliance with the
requirements, as certified to it by the Issuer, of the principal national
securities exchange, if any, on which the Notes are listed or, if the Notes are
not listed on a national securities exchange, by lot or by such other method as
the Trustee in its sole discretion shall deem equitable and reasonable; provided
that no Notes of $1,000 in principal amount at maturity or less shall be
redeemed in part.

        At the Issuer's request (which request may be revoked by the Issuer at
any time prior to the time at which the Trustee shall have given such notice to
the Holders), made in writing to the Trustee at least 60 days (or such shorter
period as shall be satisfactory to the Trustee) before a date of redemption, the
Trustee shall give a notice of redemption, at

                                       6
<PAGE>

least 30 days but not more than 60 days before the date of redemption by first
class mail to each Holder whose Notes are to be redeemed in the name and at the
expense of the Issuer. The notice of redemption shall identify the Notes to be
redeemed and shall state the date of redemption; the redemption price or the
method by which the redemption price shall be calculated; that, if any Note is
being redeemed in part, the portion of the principal amount (in integral
multiples of $1,000 in principal amount at maturity) of such Note to be
redeemed; and that, on and after the date of redemption, upon surrender of such
Note, a new Note or Notes in principal amount equal to the unredeemed portion
thereof will be reissued. Notice of redemption shall be deemed to be given when
mailed, whether or not the Holder receives the notice. In any event, failure to
receive such notice, or any defect therein, shall not affect the validity of the
proceedings for the redemption of Notes held by Holders to whom such notice was
properly mailed.

        On or prior to any date of redemption, the Issuer shall deposit with the
Paying Agent (or, if the Issuer is acting as its own Paying Agent, shall
segregate and hold in trust as provided in the Indenture) money sufficient to
pay the redemption price of and accrued interest on all Notes to be redeemed on
the date other than Notes or portions thereof called for redemption on that date
that have been delivered by the Issuer to the Trustee for cancellation.

        If notice of redemption has been given in the manner provided above, the
Notes or portion of Notes specified in such notice to be redeemed shall become
due and payable on the date of redemption at the redemption price stated
therein, together with accrued interest to such date of redemption, and on and
after such date (unless the Issuer shall default in the payment of such Notes at
the redemption price and accrued interest to the date of redemption, in which
case the principal, until paid, shall bear interest from the date of redemption
at the rate prescribed in the Notes), such Notes shall cease to accrue interest.
Upon surrender of any Note for redemption in accordance with a notice of
redemption, such Note shall be paid and redeemed by the Issuer at the redemption
price; provided that installments of interest which are payable on or prior to
the date of redemption shall be payable to the Holders registered as such at the
close of business on the relevant Regular Record Date.

        Upon surrender of any Note that is redeemed in part, the Issuer shall
execute and the Trustee shall authenticate and deliver to the Holder a new Note
equal in principal amount to the unredeemed portion of such surrendered Note.

        The Notes are not entitled to the benefits of any sinking fund.

        Upon due presentment for registration of transfer of this Note at the
office or agency of the Issuer maintained therefore, a new Note or Notes of
authorized denominations for an equal aggregate principal amount will be issued
to the transferee in exchange therefore, subject to the limitations provided in
the Indenture, without charge except for any tax or other governmental charge
imposed in connection therewith.

on account of, the principal hereof and, subject to the provisions hereof,
interest hereon, and for all other purposes, and neither the Issuer nor the
Trustee nor any agent of the Issuer or the Trustee shall be affected by any

for a Note or Notes aggregating the same principal amount as the unredeemed
principal amount of the Note or Notes surrendered. The Trustee shall be entitled
to rely on the last instruction delivered by such holder pursuant to the
preceding sentence and Section 3.01 of the Indenture unless a new instruction is
delivered 15 days prior to a payment date. The Issuer will indemnify and

                            INTERNATIONAL CORPORATION

                              7 1/8% Note due 2032

        This Note is one of a duly authorized issue of debentures, notes, bonds
or other evidences of indebtedness of the Issuer (hereinafter called the
"Securities") of the series hereinafter specified, all issued or to be issued
under and pursuant to an indenture dated as of June 28, 2002 (herein called the
"Indenture"), duly executed and delivered by the Issuer to JPMorgan Chase Bank,
as Trustee (herein called the "Trustee"), to which Indenture and all indentures
supplemental thereto reference is hereby made for a description of the rights,
limitation of rights, obligations, duties and immunities thereunder of the
Trustee, the Issuer and the holders of the Securities. The Securities may be
issued in one or more series, which different series may be issued in various
aggregate principal amounts, may mature at different times, may bear interest
(if any) at different rates, may be subject to different redemption provisions
(if any), may be subject to different sinking, purchase or analogous funds (if
any) and may otherwise vary as in the Indenture provided.

        The initial aggregate principal amount of the series of Securities of
which this Note forms a part is $250,000,000. The series of Securities of which
this Note forms a part may be reopened, without notice to or consent of the
holders of the Notes, for issuances of additional Notes of such series. The
additional Notes may be of the same tenor, interest rate and other terms as this
Note and this Note together with any such additional Notes may form a single
series. References herein to the Notes shall include (unless the context
otherwise requires) any further Notes issued as described in this paragraph.

        Interest will be computed on the basis of a 360-day year of twelve
30-day months. The Issuer shall pay interest on overdue principal and, to the
extent lawful, on overdue installments of interest at the rate pre annum borne
by this Note. If a payment date is not a Business Day, payment may be made at
the place of payment on the next succeeding day that is a Business Day, and no
interest shall accrue for the intervening period.

        In case an Event of Default, as defined in the Indenture, with respect
to the 7 1/8% Notes due 2032 shall have occurred and be continuing, the
principal hereof and the interest accrued hereon, if any, may be declared, and
upon such declaration shall become, due and payable, in the manner, with the
effect and subject to the conditions, provided in the Indenture.

        The Indenture contains provisions which permit the Issuer and the
Trustee, with the written consent of the Holders of not less than a majority in
aggregate principal amount of the Securities at the time Outstanding of each
series affected thereby (each such series voting as a separate class), to
supplement the Indenture or any supplemental

                                       5
<PAGE>

indenture or modify the rights of the holders of the Securities of such series;
provided, that no such supplemental indenture shall without the consent of the
holders of each Security so affected: (i) extend the stated maturity or reduce
the principal amount of any Security or any portion thereof, or reduce the rate
or extend the time of payment of interest thereon, or reduce any amount payable
on redemption thereof, or change the currency in which the Security is payable,
or reduce the amount of the principal of an Original Issue Discount Security
that would be due and payable upon an acceleration of the maturity thereof or
the amount thereof provable in bankruptcy, or impair or affect the right of any
holder of Securities to institute suit for the payment thereof or (ii) reduce
the aforesaid percentage of Securities of any series, the consent of the Holders
of which is required for any such supplemental indenture, or (iii) modify any
provisions of Sections 8.02 or 5.10 of the Indenture except to increase any such
percentage referred to in such provision or to provide that certain other
provisions of the Indenture cannot be modified or waived without the consent of
the holders of each Security so affected.

        It is also provided in the Indenture that an existing default or Event
of Default with respect to the Securities of any series, and its consequences,
may be waived in the manner and subject to the conditions set forth in the
Indenture, except a default in the payment of principal of or interest on any
Security or in respect of a covenant or provision of the Indenture which cannot
be modified or amended without the consent of the holder of each Outstanding
Security affected. Upon any such waiver, such default shall cease to exist and
be deemed to have been cured and not to have occurred, and any Event of Default
arising therefrom shall be deemed to have been cured and not to have occurred,
for every purpose of the Indenture; but no such waiver shall extend to any
subsequent or other default or Event of Default or impair any right consequent
thereto.

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

        The Notes are issuable initially only in registered form without coupons
in denominations of $1,000 or any integral multiple thereof and in the manner
and subject to the limitations provided in the Indenture.

        This Note is redeemable, in whole or in part, prior to maturity at the
option of the Issuer at any time or from time to time at a redemption price
equal to the greater of (i) 100% of the aggregate principal amount of the Notes
to be redeemed and (ii) as determined by an Independent Investment Banker, the
sum of the present values of the remaining scheduled payments of principal and
interest thereon (not including any portion of such payments of interest accrued
as of the date of redemption) discounted to the date of redemption on a
semi-annual basis (assuming a 360-day year consisting of twelve 30-day months)
at the Adjusted Treasury Rate (as defined below) plus 30 basis points, plus, in
each case, accrued and unpaid interest thereon to the date of redemption.

                                       6
<PAGE>

        "Adjusted Treasury Rate" means, with respect to any redemption date, the
rate per annum equal to the semi-annual equivalent yield to maturity (computed
as of the third Business Day immediately preceding the redemption date) 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, calculated in accordance with standard
market practice.

         "Comparable Treasury Issue" means the United States Treasury security
selected by an Independent Investment Banker that would be used, 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 Notes.

        "Comparable Treasury Price" means, with respect to any redemption date,
either (i) the average of the Reference Treasury Dealer Quotations for such
redemption date, after excluding the highest and lowest such Reference Treasury
Dealer Quotations, or (ii) if the Trustee obtains fewer than three such
Reference Treasury Dealer Quotations, the average of all such Reference Treasury
Dealer Quotations obtained.

        "Independent Investment Banker" means one of the Reference Treasury
Dealers appointed by the Issuer.

        "Reference Treasury Dealer" means each of J.P. Morgan Securities Inc.
(and its successors), and any other nationally recognized investment banking
firm that is a primary U.S. Government securities dealer specified from time to
time by the Issuer. If, however, any of them ceases to be a primary U.S.
Government securities dealer, the Issuer shall substitute another nationally
recognized investment banking firm that is such a dealer.

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

        If less than all of the Notes are to be redeemed at any time, the
Trustee shall select the Notes to be redeemed in compliance with the
requirements, as certified to it by the Issuer, of the principal national
securities exchange, if any, on which the Notes are listed or, if the Notes are
not listed on a national securities exchange, by lot or by such other method as
the Trustee in its sole discretion shall deem equitable and reasonable; provided
that no Notes of $1,000 in principal amount at maturity or less shall be
redeemed in part.

        At the Issuer's request (which request may be revoked by the Issuer at
any time prior to the time at which the Trustee shall have given such notice to
the Holders), made in writing to the Trustee at least 60 days (or such shorter
period as shall be satisfactory to the Trustee) before a date of redemption, the
Trustee shall give a notice of redemption, at

                                       7
<PAGE>

least 30 days but not more than 60 days before the date of redemption by first
class mail to each Holder whose Notes are to be redeemed in the name and at the
expense of the Issuer. The notice of redemption shall identify the Notes to be
redeemed and shall state the date of redemption; the redemption price or the
method by which the redemption price shall be calculated; that, if any Note is
being redeemed in part, the portion of the principal amount (in integral
multiples of $1,000 in principal amount at maturity) of such Note to be
redeemed; and that, on and after the date of redemption, upon surrender of such
Note, a new Note or Notes in principal amount equal to the unredeemed portion
thereof will be reissued. Notice of redemption shall be deemed to be given when
mailed, whether or not the Holder receives the notice. In any event, failure to
receive such notice, or any defect therein, shall not affect the validity of the
proceedings for the redemption of Notes held by Holders to whom such notice was
properly mailed.

        On or prior to any date of redemption, the Issuer shall deposit with the
Paying Agent (or, if the Issuer is acting as its own Paying Agent, shall
segregate and hold in trust as provided in the Indenture) money sufficient to
pay the redemption price of and accrued interest on all Notes to be redeemed on
the date other than Notes or portions thereof called for redemption on that date
that have been delivered by the Issuer to the Trustee for cancellation.

        If notice of redemption has been given in the manner provided above, the
Notes or portion of Notes specified in such notice to be redeemed shall become
due and payable on the date of redemption at the redemption price stated
therein, together with accrued interest to such date of redemption, and on and
after such date (unless the Issuer shall default in the payment of such Notes at
the redemption price and accrued interest to the date of redemption, in which
case the principal, until paid, shall bear interest from the date of redemption
at the rate prescribed in the Notes), such Notes shall cease to accrue interest.
Upon surrender of any Note for redemption in accordance with a notice of
redemption, such Note shall be paid and redeemed by the Issuer at the redemption
price; provided that installments of interest which are payable on or prior to
the date of redemption shall be payable to the Holders registered as such at the
close of business on the relevant Regular Record Date.

        Upon surrender of any Note that is redeemed in part, the Issuer shall
execute and the Trustee shall authenticate and deliver to the Holder a new Note
equal in principal amount to the unredeemed portion of such surrendered Note.

        The Notes are not entitled to the benefits of any sinking fund.

        Upon due presentment for registration of transfer of this Note at the
office or agency of the Issuer maintained therefore, a new Note or Notes of
authorized denominations for an equal aggregate principal amount will be issued
to the transferee in exchange therefore, subject to the limitations provided in
the Indenture, without charge except for any tax or other governmental charge
imposed in connection therewith.
