         assume any obligation 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,

         Agreement shall be sufficient if signed by any person who the
         Calculation Agent reasonably believes to be a duly authorized officer
         or attorney-in-fact of the Company or the Trustee, as the case may be;

         such duties as are set out specifically herein and any duties

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
Company and specifying such removal and the date when it shall become effective.
Such resignation or removal shall take effect upon the appointment by the

                                                                               3

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
then unpaid, shall thereupon become obligated to transfer, deliver and pay over,
and such successor Calculation Agent shall be entitled to receive, all moneys,
securities and other property on deposit with or held by such predecessor, as
Calculation Agent hereunder.

                                     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 July 29, 2002, the component companies of the Dow Jones
Industrial Average were as follows: 3M Company, Alcoa 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, Philip Morris Companies.
Inc., 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 Capped Quarterly Returns
for each of the 20 Measurement Periods, (ii) the Equity Bonus and (iii) the
amount payable at Stated Maturity for each $1,000 principal amount of Securities
(the "Maturity Payment Amount").

         The Maturity Payment Amount shall equal the sum of (a) $1,125 and (b)
the Equity Bonus.

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 Capped Quarterly Returns for each Measurement Period
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 Capped Quarterly Return
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, the date that any Capped Quarterly Return
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 Capped Quarterly Return to be used in

                                      A-1





computing the Equity Bonus. The Ending Index Level to be used in computing the
Capped Quarterly Return 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 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.

4.       Alteration of Method of Calculation.

         If at any time the method of calculating the Index or a Successor
Index, or the Ending Index Level to be used in computing the Capped Quarterly
Return, 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 Ending Index Level to be used in computing the Capped
Quarterly Return 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 Capped Quarterly Returns and the Equity Bonus 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., as if such split had not occurred).

     case, for more than two hours of trading or during the one-half hour period
     preceding the Close of Trading on the primary organized U.S. exchange or
     trading system on which those stocks are traded or, if in the case of a
     common stock not listed or quoted in the United States, on the primary
     exchange, trading system or market for that security. Limitations on

     trading system or market on which those options contracts are traded or
     otherwise.

         (iii) Information is unavailable on that date, through a recognized
     system of public dissemination of transaction information, for more than

     trading system or market.

     For purposes of determining whether a Market Disruption Event has occurred:

         (i) a limitation on the hours or number of days of trading shall not

     set by that 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

         (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
