Maturity Date:............... means April 30, 2008.

Cash Settlement Value

            At Maturity, the Company shall pay the "Cash Settlement Value," an
amount in cash depending on the relation of the Final Index Level to the Initial
Index Level:

                  (i) If the Final Index Level is greater than or equals the
                  Initial Index Level, the Cash Settlement Value per each $1,000
                  principal amount of Notes will equal:


                                _                                       _
                               [                                         ]
                               |          ( Final Index Level        )   |
            $1,000 + $1,000 x  |  150% x  (-------------------   -  1)   |

                  (ii) If the Final Index Level is less than the Initial Index
                  Level, the Cash Settlement Value per each $1,000 principal
                  amount of Notes will equal:




                               ( Final Index Level )
                     $1,000 x  (-------------------)

<PAGE>

Discontinuance of the Index

            If Dow Jones and AIGI discontinue publication of the Index and they
or another entity publish a successor or substitute index that the Calculation
Agent determines, in its sole discretion, to be comparable to the discontinued
Index (the new index being referred to as a "successor index"), then the Final
Index Level will be determined by reference to the successor index at the close
of trading on the relevant exchange or market for the successor index on the
date that the Final Index Level is to be determined.

            If Dow Jones and AIGI discontinue publication of the Index prior to,
and such discontinuance is continuing on, the date that the Final Index Level is
to be determined and the Calculation Agent determines that no successor index is
available at such time, then, on such date, the Calculation Agent will notify
the Company and the Trustee, and will calculate the Index by reference to a
group of physical commodities, exchange-traded futures contracts on physical
commodities or indices and will apply a computation methodology that the
Calculation Agent determines will as closely as reasonably possible replicate
the Index. "Closing level" means, with respect to any security on any date, the
last reported sales price regular way on such date or, in case no such reported
sale takes place on such date, the average of the reported closing bid and asked
price regular way on such date, in either case on the primary organized exchange
or trading system on which such physical commodities, exchange-traded futures
contracts on physical commodities or indices are then listed or admitted to
trading.

            If a successor index is selected, or the Calculation Agent
calculates a value as a substitute for the Index as described above, that
successor index or its closing level will be used as a substitute for the Index
for all purposes, including for purposes of determining whether an Index
Business Day or Market Disruption Event has occurred or exists.

Adjustments to the Index

            If at any time the method of calculating the Index or a successor
index, or the Final Index Level thereof, is changed in a material respect, or if
the Index or a successor index is in any other way modified so that such index
does not, in the opinion of the Calculation Agent, fairly represent the level of
the Index or such successor index had such changes or modifications not been
made, then, from and after such time, the Calculation Agent will, at the close
of business in New York City on the date that the Final Index Level is to be
determined, make such calculations and adjustments as, in its good faith
judgment, may be necessary in order to arrive at a level of a commodity index
comparable to the Index or such successor index, as the case may be, as if such
changes or modifications had not been made. The Calculation Agent will calculate
the Final Index Level with reference to the Index or such successor index, as
adjusted.

Market Disruption Events

            If there is a Market Disruption Event (a "Market Disruption Event")
on the Calculation Date, the Calculation Date will be the first succeeding Index
Business Day on which there is no Market Disruption Event, unless there is a
Market Disruption Event on the next Index Business Day following the original
date that, but for the Market Disruption Event, would have been the Calculation
Date. In that case, the first Index Business Day will be deemed to be the
Calculation Date, notwithstanding the Market Disruption Event and the
Calculation Agent will


                                      -6-
<PAGE>

determine the level of the Index on that first Index Business Day in accordance
with the formula for and method of calculating the Index in effect prior to the
Market Disruption Event using the exchange traded price of each commodity in the
Index (or, if trading in any such commodity has been materially suspended or
materially limited, the Calculation Agent's good faith estimate of the exchange
traded price that would have prevailed but for such suspension or limitation) as
of that first Index Business Day.

            A Market Disruption Event means any of the following events, as
determined by the Calculation Agent, in its sole discretion:

      o     the termination or suspension of, or material limitation or
            disruption of trading for more than three hours in any futures
            contract used in the calculation of the Index or any successor
            index;

      o     the official price as published by the futures exchange on which the
            Index commodity trades (the "settlement price") for any Index
            commodity has increased or decreased by the maximum permitted price
            change from the previous day's settlement price;

      o     the failure of an exchange to publish a settlement price for any
            respective Index commodity;

      o     with respect to any Index commodity that trades on the London Metal
            Exchange ("LME"), a business day on which the LME is not open for
            trading; or

      o     in any other event, if the Calculation Agent determines in its sole
            discretion that the event materially interferes with the Company's
            ability or the ability of any of the Company's affiliates to manage,
            enter into or unwind a hedge with respect to the Notes that the
            Company or its affiliates have effected or may effect.

The following events will not be Market Disruption Events:

      a)    a limitation on the hours or numbers of days of trading, but only if
            the limitation results from an announced change in the regular
            business hours of the futures exchange in which an Index commodity
            trades; or

      b)    a decision to permanently discontinue trading in the option or
            futures contracts relating to the Index or Index commodity.

Redemption; Defeasance

            The Notes are not subject to redemption before Maturity, and are not
subject to defeasance.

Events of Default and Acceleration

            If an Event of Default with respect to any Notes has occurred and is
continuing, then the amount payable to the beneficial owner of a Note, upon any
acceleration permitted by the Notes will be equal to the Cash Settlement Value
as though the date of early repayment were the Maturity Date of the Notes,
adjusted by an amount equal to any losses, expenses and costs

                                      -7-
<PAGE>

to the Company of unwinding any underlying or related hedging or funding
arrangements, all as determined by the Calculation Agent in its sole and
absolute discretion.

Same-Day Settlement and Payment

            Payment of the Cash Settlement Value will be made in immediately
available funds, so long as the Notes are maintained in book-entry form.

Calculation Agent

            All determinations made by the Calculation Agent will be at the sole
discretion of the Calculation Agent and will, in the absence of manifest error,
be conclusive for all purposes and binding on the Company and Holders of the
Notes.

General

            If so specified on the face of this Note, this Note may be redeemed
by the Company on and after the date so indicated on the face hereof. If no such
date is set forth on the face hereof, this Note may not be redeemed prior to

amount to be redeemed, together with interest thereon payable to the Redemption
Date, on notice given, unless otherwise specified on the face hereof, not more
than 60 nor less than 30 days prior to the Redemption Date. If less than all the
Outstanding Notes having such terms as specified by the Company are to be
redeemed, the particular Notes to be redeemed shall be selected by the Trustee
not more than 60 days prior to the Redemption Date from the Outstanding Notes
having such terms as specified by the Company not previously called for

notice of such redemption shall specify which Notes are to be redeemed. In the
event of redemption of this Note, in part only, a new Note or Notes in
authorized denominations for the unredeemed portion hereof shall be issued in
the name of the Holder hereof upon the surrender hereof.

            If so specified on the face of this Note, this Note will be subject
to repayment at the option of the Holder hereof on the Optional Repayment
Date(s). If no Optional Repayment Date is set forth on the face hereof, this

to be repaid, together with interest thereon payable to the Optional Repayment
Date. For this Note to be repaid in whole or in part at the option of the Holder
hereof, the Trustee must receive not less than 30 nor more than 60 days prior to
the Optional Repayment Date (i) this Note with the form entitled "Option to
Elect Repayment," which appears below, duly completed or (ii) a telegram, telex,
facsimile transmission or a letter from a member of a national securities

bank or trust company in the United States of America setting forth the name of
the Holder of this Note, the principal amount of this Note, the certificate
number of this Note or a description of this Note's tenor or terms, the
principal amount of this Note to be repaid, a statement that the option to elect

<PAGE>

five Business Days after the date of such telegram, telex, facsimile
transmission or letter and this Note and such form duly completed are received
by the Trustee by such fifth Business Day. Exercise of the repayment option
shall be irrevocable.

            If any Event of Default with respect to the Notes shall occur and be
continuing, the Trustee or the Holders of not less than 25% in principal amount
of the Outstanding Notes may declare the principal of all the Notes 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 under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of 66-2/3% in aggregate principal amount of the
Securities at the time Outstanding of each series affected thereby. The
Indenture also contains provisions permitting the Holders of specified
percentages in aggregate principal amount of the Securities of each series at
the time Outstanding, on behalf of the Holders of all Securities of each 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 future Holders of this Note and of any Note issued
upon the registration of transfer hereof or in exchange hereof or in lieu hereof
whether or not notation of such consent or waiver is made upon this Note.

            Holders of Securities may not enforce their rights pursuant to the
Indenture or the Securities except as provided in the Indenture. No reference
herein to the Indenture and no provision of this Note or the Indenture shall
alter or impair the obligation of the Company, which is absolute and
unconditional, to pay the Cash Settlement Value with respect to 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

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

the Holder hereof or by his 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.

or exchange, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith.
