     following, to all of which the Company agrees:

               (a) in acting under this Agreement, the Calculation Agent is
          acting solely as an independent expert of the Company and does not
          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,
          certificate, notice, request, direction or other communication from
          the Company or the Trustee made or given under any provision of this
          Agreement shall be sufficient if signed by any person whom 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;

               (c) the Calculation Agent shall be obliged to perform only such
          duties as are set out specifically herein and any duties necessarily
          incidental thereto;

               (d) the Calculation Agent, whether acting for itself or in any
          other capacity, may become the owner or pledgee of Securities with the
          same rights as it would have had if it were not acting hereunder as
          Calculation Agent; and

               (e) the Calculation Agent shall incur no liability hereunder
          except for loss sustained by reason of its gross negligence or willful
          misconduct.

          6. Resignation; Removal; Successor. (a) The Calculation Agent may at
     any time resign by giving written notice to the Company of such intention
     on its part, specifying the

     date on which its desired resignation shall become effective, subject to
     the appointment of a successor Calculation Agent and acceptance of such
     appointment by such successor Calculation Agent, as 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
     Company, as hereinafter provided, of a successor Calculation Agent and the
     acceptance of such appointment by such successor Calculation Agent. In the
     event a successor Calculation Agent has not been appointed and has not
     accepted its duties within 90 days of the Calculation Agent's notice of
     resignation, the Calculation Agent may apply to any court of competent
     jurisdiction for the designation of a successor Calculation Agent.

               (b) In case at any time the Calculation Agent shall resign, or
     shall be removed, or shall become incapable of acting, or shall be adjudged
     bankrupt or insolvent, or make an assignment for the benefit of its
     creditors or consent to the appointment of a receiver or custodian of all
     or any substantial part of its property, or shall admit in writing its
     inability to pay or meet its debts as they mature, or if a receiver or
     custodian of it or all or any substantial part of its property shall be
     appointed, or if any public officer shall have taken charge or control of
     the Calculation Agent or of its property or affairs, for the purpose of
     rehabilitation, conservation or liquidation, a successor Calculation Agent
     shall be appointed by the Company by an instrument in writing, filed with
     the successor Calculation Agent. Upon the appointment as aforesaid of a
     successor Calculation Agent and acceptance by the latter of such
     appointment, the Calculation Agent so superseded shall cease to be
     Calculation Agent hereunder.

               (c) Any successor Calculation Agent appointed hereunder shall
     execute, acknowledge and deliver to its predecessor, to the Company and to
     the Trustee an instrument accepting such appointment hereunder and agreeing
     to be bound by the terms hereof, and thereupon such successor Calculation

     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.

               (d) Any corporation into which the Calculation Agent hereunder

     the Calculation Agent shall be the successor Calculation Agent under this
     Agreement without the execution or filing of any paper or any further act
     on the part of any of the parties hereto.


                                                                               4

                         [Calculation Agency Agreement]


                                     ANNEX A
                                     -------

     1.   The Index.

          The Index is the Dow Jones Global Titans 50 Index (the "Index"), as
calculated, published and disseminated by Dow Jones & Company, Inc. ("Dow
Jones").

     2.   Determination of the Maturity Payment Amount.

          The Calculation Agent shall, at the request of the Trustee, determine
the amount payable on the Stated Maturity Date for each $1,000 principal amount
of Securities (the "Maturity Payment Amount").

          The Maturity Payment Amount shall be the greater of the following:

                  (1) $1,000; and

                  (2) the Alternative Redemption Amount.

     3.   Discontinuance of the Index.

     (a) If 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 to be comparable to the discontinued
Index, then the Calculation Agent shall determine the Closing Index Level to be
used for purposes of computing the Alternative Redemption Amount and the
Maturity Payment Amount by reference to the Closing Index level of such
Successor Index on the applicable date.

     (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 and the Calculation
Agent determines that no Successor Index is available at such time, or if Dow
Jones (or the publisher of any Successor Index) fails to calculate and announce
a Closing Index Level for the Index (or a Successor Index) on any date when it
would ordinarily do so in accordance with its customary practice, the
Calculation Agent will determine the Closing Index Level to be used for purposes
of computing the Alternative Redemption Amount and the amount payable on the
Stated Maturity Date. In such circumstances, the Closing Index Level will be
computed by the Calculation Agent in accordance with the formula for and method
of calculating the Index (or any Successor Index) last in effect prior to such
discontinuance, using the Closing Price (or, if trading in any of the relevant
securities has been materially suspended or materially limited, its good faith
estimate of the Closing Price that would have prevailed but for such suspension
or limitation) at the Close of Trading on such date of each security most
recently comprising the Index (or any Successor Index) on the Relevant Exchange
for such security.

     4.   Alteration of Method of Calculation.


                                                                               2


     If at any time the method of calculating the Index, any Successor Index, or
the Closing Index Level on any particular day, 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 of the Relevant Exchanges on which the securities comprising
the Index or such Successor Index traded on any date the Closing 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 Closing Index Level on any particular day
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 (for example, 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 (for example, if such split had not occurred).

     5.   Definitions.

          Set forth below are the terms used in the Agreement and in this Annex
A.

          "Average Closing Index Level" shall mean the arithmetic average of the
Closing Index Level on five annual dates, which shall be February of each year,
from and including February 4, 2006 to and including the Valuation Date;
provided that if the Calculation Agent determines that one or more Market
Disruption Events have occurred on one of these dates, the Calculation Agent
will determine the Closing Index Level for such date by reference to the Closing
Index Level on the next Exchange Business Day on which there is not a Market
Disruption Event; provided, however, if a Market Disruption Event occurs on each
of the eight Exchange Business Days following the originally scheduled Valuation
Date, then (a) that eighth Exchange Business Day shall be deemed the Valuation
Date and (b) the Calculation Agent shall


                                                                               3

          "Average Execution Price" shall mean, for a security or other

mean any day that is not a Saturday, a Sunday or a day on which the NYSE, Nasdaq

other exchange or quotation system, the scheduled weekday closing time on a day
on which the exchange or quotation system is scheduled to be open for trading
for its respective regular trading session, without regard to after hours or any
other trading outside of the regular trading sessions.

          "Closing Price" shall mean, for each security (or any combination
thereof then included in the Index or any Successor Index or used by the
Calculation Agent in calculating the Closing Index Level), as determined by the
Calculation Agent pursuant to this Agreement, based on information reasonably
available to it, on any particular day:

          (i) if the security is listed on a Relevant Exchange, the last
reported sale price per share at the Close of Trading on such day on the
Relevant Exchange;

          (ii) if the security is not listed on a national securities exchange
or quotation system or is not a Nasdaq security, and is listed or traded on a
bulletin board, the Average Execution Price per share of the security; and

          (iii) in the case of both (i) and (ii) above, if the security is
listed or quoted on a non-United States Relevant Exchange or on a non-United
States bulletin board, the Closing Price will then be converted into U.S.
dollars using the Official W.M. Reuters Spot Closing Rate at 11:00 a.m., New
York City time. If there are several quotes for the Official W.M. Reuters Spot
Closing Rate at that time, the first quoted rate starting at 11:00 a.m. shall be
the rate used. If there is no such Official W.M. Reuters Spot Closing Rate for a
country's currency at 11:00 a.m., New York City time, the Closing Price shall be
converted into U.S. dollars using the last available U.S. dollar cross-rate
quote before 11:00 a.m., New York City time.

          "Closing Index Level" shall mean, with respect to any day, in the case
of the Index or the Successor Index, the closing level of the Index or the
Successor Index, as the case may be, as reported by Dow Jones or the publisher
of the Successor Index, as the case may be, on such day or as determined by the
Calculation Agent pursuant to this Agreement.


                                                                               4

determined by the Calculation Agent:

     (1) A material suspension of or limitation imposed on trading relating to
     the securities that then comprise 20% or more of the Index or any Successor
     Index, by the Relevant Exchanges on 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 Relevant Exchange. Limitations on trading during
     significant market fluctuations imposed pursuant to NYSE Rule 80B or any
     applicable rule or regulation enacted or promulgated by the NYSE, any other
     exchange, quotation system or market, any other self regulatory
     organization or the Securities and Exchange Commission of similar scope or
     as a replacement for Rule 80B may be considered material.

     (2) A material suspension of, or limitation imposed on, trading in futures
     or options contracts relating to the Index or any Successor Index by the
     primary exchange or quotation system on which those futures or options
     contracts 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 the exchanges or otherwise.

     (3) 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 Relevant Exchanges on which those
     securities are traded, at any time during the one hour period that ends at
     the Close of Trading on such day.

     (4) 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 futures or options contracts relating to the
     Index or any Successor Index on the primary exchange or quotation system on
