                                            By:___________________________

                                               Title:


                                            LEHMAN BROTHERS INC.,
                                              as Calculation Agent

                                            By:__________________________
                                               Name:
                                               Title:



                                    ANNEX A

     1. The Index.

     The Index is the S&P 500 Index (the "Index"), as calculated, published
and disseminated by Standard & Poor's, a division of McGraw-Hill, Inc.
("S&P").

     The Index is a capitalization-weighted index of 500 stocks designed to
measure performance of the broad domestic economy through changes in the
aggregate market value of 500 stocks representing all major industries.
Standard & Poor's chooses companies for inclusion in the Index with the aim of
achieving a distribution by broad industry groupings that approximates the
distribution of these groupings in the common stock population of The New York
Stock Exchange (the "NYSE"), which Standard & Poor's uses as an assumed model
for the composition of the total market. As of November 3, 2003, the 500
companies included in the Index were divided into ten industry groups:
Consumer Discretionary, Consumer Staples, Energy, Financials, Health Care,
Industrials, Information Technology, Materials, Telecommunications Services
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 S&P discontinues publication of the Index and S&P 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
NYSE 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 S&P 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 S&P 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


                                                                             2

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 the 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).
