   toward, or any relationship of agency or trust for or with, any of the
   holders of the Securities;

     (b) unless otherwise specifically provided herein, any order, certificate,
   notice, request, direction or other communication from the Company or the

hereinafter provided. The Calculation Agent hereunder may be removed at any time
by the filing with it of an instrument in writing signed by or on behalf of the

                                        LEHMAN BROTHERS INC.,
                                          as Calculation Agent


                                        By:
                                           -------------------------------------
                                           Name: Karen Corrigan
                                           Title: Vice President




                                     ANNEX A
                                     -------

     1. The Index.

     The Index is the Dow Jones Industrial Average(SM), as calculated by Dow
Jones & Company, Inc. (the "Index").

     The Index is a price-weighted index of 30 common stocks chosen by the
editors of The Wall Street Journal as representative of a broad cross-section of
U.S. industry. As of April 24, 2003, the component companies of the Dow Jones
Industrial Average were as follows: 3M Company, Alcoa Inc., Altria Group, Inc.,
American Express Company, AT&T Corp., The Boeing Company, Caterpillar Inc.,
Citigroup Inc., The Coca-Cola Company, E.I. du Pont de Nemours and Company,
Eastman Kodak Company, Exxon Mobil Corporation, General Electric Company,
General Motors Corporation, Hewlett-Packard Company, The Home Depot, Inc.,
Honeywell International Inc., Intel Corporation, International Business Machines
Corporation, International Paper Company, J.P. Morgan Chase & Co., Johnson &
Johnson, McDonald's Corporation, Merck & Co., Inc., Microsoft Corporation, The
Procter & Gamble Company, SBC Communications Inc., United Technologies
Corporation, Wal-Mart Stores, Inc. and The Walt Disney Company.

     2. Determination of the Maturity Payment Amount.

     The Calculation Agent shall determine (i) the Adjusted 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 Dow Jones & Company, Inc. ("Dow Jones") discontinues publication of
the Index and Dow Jones 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 Calculation
Agent shall calculate the Maturity Payment Amount pursuant to Section 2 hereof
by reference to the index level of such Successor Index at the Close of Trading
on the NYSE, AMEX, Nasdaq or the relevant exchange or market for the Successor
Index on the date that any subsequent Closing 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 Dow Jones discontinues publication of the Index prior to, and such
discontinuance is continuing on, any date that a Closing 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 shall
determine the Closing Level to be used in computing the Adjusted Final Index
Level and the Maturity Payment Amount. Each such Closing Level shall 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



                                                                               2

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 organized U.S.
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 Closing Level to be used in computing the Alternative Redemption Amount, 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 value 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 in New York City on
the date that the Final Index Level to be used in computing the Alternative
Redemption Amount 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, and calculate the Closing Level and the Maturity Payment Amount with
reference to the Index or such Successor Index, as adjusted. Accordingly, 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 (e.g., due to a split in the index), then the Calculation Agent shall
adjust such index in order to arrive at a level of the Index or such Successor
Index as if it had not been modified (e.g., if such split had not occurred).

     5. Definitions.

     or trading system or, in the case of securities of a non-U.S. issuer,

     set by such securities market, (b) an imbalance of orders relating to those
     contracts, or (c) a disparity in bid and ask quotes relating to those
     contracts, shall constitute a Market Disruption Event notwithstanding that
     the suspension or material limitation is less than two hours;

         (iii) a suspension or material limitation on an exchange, trading
     system or in a market shall include a suspension or material limitation of
     trading by one class of investors provided that the suspension continues
     for more than two hours of trading or during the last one-half hour period
     preceding the Close of Trading on the relevant exchange, trading system or
     market but shall not include any time when the relevant exchange, trading
     system or market is closed for trading as part of that exchange's, trading
