acceptance of such appointment by such successor Calculation Agent, as
hereinafter provided. The Calculation Agent hereunder may be removed at any time

without any further act, deed or conveyance, shall become vested with all the
authority, rights, powers, trusts, immunities, duties and obligations of such
predecessor with like effect as if originally named as Calculation Agent
hereunder, and such predecessor, upon payment of its charges and disbursements

                                                 Title:   Vice President



                                            LEHMAN BROTHERS INC.,
                                              as Calculation Agent


                                            By:__________________________
                                                 Name: Oliver Budde
                                                 Title:   Vice President





                                     ANNEX A

         1. The Index.

            The Index is the Nikkei Stock Average, as calculated, published and
disseminated by Nihon Keizai Shimbun, Inc. (the "Index").

            The Index measures the composite price performance of selected
Japanese stocks. The Index is currently based on 225 underlying stocks trading
on the Tokyo Stock Exchange (the "TSE") and represents a broad cross-section of
Japanese industry. All 225 of the stocks underlying the Index are stocks listed
in the First Section of the TSE. Stocks listed in the First Section are among
the most actively traded stocks on the TSE. As of September 5, 2003, the 225
companies included in the Index were divided into six sector categories:
Technology, Financials, Consumer Goods, Materials, Capital Goods/Others and
Transportation and Utilities.

         2. Determination of the Maturity Payment Amount.

            The Calculation Agent shall determine (i) the Final Index Level and
(ii) the amount payable on the Stated Maturity Date for each $1,000 principal
amount of Securities (the "Maturity Payment Amount").

            The Maturity Payment Amount, for each $1,000 principal amount of
Securities, shall be equal to the greater of (a) $1,000 and (b) the Alternative
Redemption Amount

         3. Discontinuance of the Index.

         (a) If Nihon Keizai Shimbun, Inc. ("NKS") discontinues publication of
the Index and NKS or another entity publishes a successor or substitute index
(the "Successor Index") that the Calculation Agent determines, in its sole
discretion, to be comparable to the discontinued Index, then the Final Index
Level will be determined by reference to the level of such Successor Index at
the Close of Trading on the TSE or the relevant exchange or market for the
Successor Index on the date the Final Index Level is to be determined.

         (b) Upon any selection by the Calculation Agent of a Successor Index,
the Company shall promptly give notice to the holders of the Securities.

         (c) If NKS discontinues publication of the Index prior to, and such
discontinuance is continuing on, the date the Final Index Level is to be
determined and the Calculation Agent determines that no Successor Index is
available at such time, or if NKS fails to calculate and announce a Closing
Level for the Index on the date the Final Index Level is to be determined, then,
on such date, the Calculation Agent will determine the Final Index Level to be
used in computing the Alternative Redemption Amount. The Final Index Level will
be computed by the Calculation Agent in accordance with the formula for and
method of calculating the Index last in effect prior to such discontinuance,
using the Closing Level (or, if trading in the relevant securities has been
materially suspended or materially limited, its good faith estimate of the
Closing Level that would have prevailed but for such suspension or limitation)
at the close of the principal trading session on such date of each security most
recently comprising the Index on the primary exchange or trading system on which
such securities trade.





         4. Alteration of Method of Calculation.

            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 Trading of any primary exchange or quotation system on which each security
comprising the Index or such Successor Index is traded on the date the Final
Index Level is to be determined, make such calculations and adjustments as, in
the good faith judgment of the Calculation Agent, may be necessary in order to
arrive at a level of a stock 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 and the
Alternative Redemption Amount with reference to the Index or such Successor
Index, as adjusted.

            If the method of calculating the Index or a Successor Index is
modified so that the level of such index is a fraction of what it would have
been if it had not been modified (for example, due to a split in the index),
then the Calculation Agent will adjust such index in order to arrive at a level
of the Index or such Successor Index as if it had not been modified (for
example, as if such split had not occurred).

         5. Definitions.

            Set forth below are definitions of the terms used in the Agreement

         which those securities are traded, at any time during the one-hour
         period that ends at the Close of Trading on such day, whether by reason
         of movements in price exceeding limits permitted by that primary
         exchange or quotation system or otherwise.

                  (ii) A material suspension of or limitation imposed on trading
         in futures or options contracts relating to the Index or any Successor

         one-hour period that ends at the Close of Trading on such day, whether
         by reason of movements in price exceeding limits permitted by that
         primary exchange or quotation system or otherwise.

                  (iii) Any event, other than an early closure, that disrupts or
         impairs the ability of market participants in general to effect
         transactions in, or obtain market values for, the securities that then
         comprise 20% or more of the Index or any Successor Index on the primary
         exchange or quotation system on which those securities are traded at
         any time during the one-hour period that ends at the Close of Trading
         on such day.

                  (iv) Any event, other than an early closure, that disrupts or
         impairs the ability of market participants in general to effect
         transactions in, or obtain market values for, futures or options
         contracts relating to the Index or any Successor Index on the primary
         exchange or quotation system on which those futures or options

         at the Close of Trading on such day.

                  (v) The closure of the primary exchange or quotation system on
         which securities that then comprise 20% or more of the Index or any

         deadline for orders to be entered into the primary exchange or

         using commercially reasonable efforts to unwind or dispose of, or
         realize, recover or remit the proceeds, of any transactions or assets
         it deems necessary to hedge the equity price risk of entering into and
         performing its obligations with respect to the Securities.







                  For purposes of determining whether a Market Disruption Event
         has occurred the relevant percentage contribution of a security to the
         level of the Index or any Successor Index will be based on a comparison
         of (x) the portion of the level of the index attributable to that
         security and (y) the overall level of the index, in each case
         immediately before the occurrence of the Market Disruption Event.
