ADDITIONAL TERMS

Interest Rates

During the period commencing with the Original Issue Date to but excluding
October 15, 2003, the Notes will bear interest at a rate of 5.335% per annum
and interest will be computed and paid on the basis of a 360-day year of twelve
30-day months.

If the Calculation Agent has not given the Put Notice (as defined below)
or the Company has not repurchased the Notes (see Reset of Interest Rate for
Second Fixed Rate Period below), then during the period from and including
October 15, 2003 to the Maturity Date, the Notes will bear interest at a fixed
rate calculated as described below (see Reset of Interest Rate for Second
Fixed Rate Period below).

Put Option

The Calculation Agent has the right to require the Company to repurchase all
(but not less than all) of the Notes on October 15, 2003 at a purchase price
equal to 100% of the principal amount thereof, plus accrued but unpaid interest
to but excluding October 15, 2003 (the Redemption Price), by delivering
written notice thereof to the Company on behalf of all (but not fewer than all)
holders of the Notes (the Put Notice). Such Put Notice shall be given no
later than 9:00 a.m. (New York time) on October 8, 2003. The Calculation Agent
shall give the Put Notice if the holders of a majority in principal amount of
the Notes request the Calculation Agent to give the Put Notice, in which event
the Put Notice shall be binding on all Noteholders; the Calculation Agent shall
not give the Put Notice absent such request of the holders of a majority in
principal amount of the Notes. In the event the Put Notice is timely given,
the Company shall repurchase the Notes at the Redemption Price on October 15,
2003.

If required by the Calculation Agent, each holder shall indicate its election
to have the Calculation Agent deliver the Put Notice to the Company by
delivering written notice of such election to the Calculation Agent by no later
than 12:00 noon (New York time) on October 6, 2003.

Reset of Interest Rate for Second Fixed Rate Period

accordance with the terms set forth under Put Option above, the Company and
the Calculation Agent, on October 8, 2003, shall undertake the following
actions to calculate the fixed rate of interest to be paid on the Notes during
the period from and including October 15, 2003 to the Maturity Date. All
references to specific hours are references to prevailing New York time. Each
notice, bid or offer (including those given by the Reference Dealers [as
defined below]) shall be given telephonically and shall be confirmed as soon as
possible by facsimile to each of the Calculation Agent and the Company. The
times set forth below are guidelines for action by the Company and the
