     Title:  Authorized Signatory

                                                                               4

                               Reverse of Security

                  This Security is one of a duly authorized series of Securities
of the Company designated as Index-Plus Notes Due December 23, 2009, Performance
Linked to Russell 2000(R) Index (RTY) (herein called the "Securities"). The
Company may, without the consent of the holders of the Securities, create and
issue additional notes ranking equally with the Securities and otherwise similar
in all respects so that such further notes shall be consolidated and form a
single series with the Securities; provided that no additional notes can be
issued if an Event of Default has occurred with respect to the Securities. This
series of Securities is one of an indefinite number of series of debt securities
of the Company, issued and to be issued under an indenture, dated as of
September 1, 1987, as amended (herein called the "Indenture"), duly executed and
delivered by the Company and Citibank N.A., as trustee (herein called the
"Trustee", which term includes any successor trustee under the Indenture), to
which Indenture and all indentures supplemental thereto reference is hereby made
for a description of the rights, limitations of rights, obligations, duties and
immunities thereunder of the Company, the Trustee and the Holders of the
Securities.

                  The Maturity Payment Amount, at the request of the Trustee,
shall be determined by the Calculation Agent pursuant to the Calculation Agency
Agreement.

                  All percentages resulting from any calculation with respect to
the Securities will be rounded at the Calculation Agent's discretion.

                  The Trustee shall fully rely on the determination by the
Calculation Agent of the Maturity Payment Amount and shall have no duty to make
any such determination.

                  This Security is not subject to any sinking fund.

                  If an Event of Default with respect to the Securities shall
occur and be continuing, the amounts payable on all of the Securities may be
declared due and payable in the manner and with the effect provided in the
Indenture. The amount payable to the Holder hereof upon any acceleration
permitted under the Indenture will be equal to the Maturity Payment Amount
calculated as though the date of acceleration was the Stated Maturity Date and
the date three Business Days prior thereto was the Valuation Date.

                  The Indenture contains provisions permitting the Company and
the Trustee, with the consent of the holders of not less than 66 2/3% in
aggregate principal amount of each series of Securities at the time Outstanding
to be affected (each series voting as a class), evidenced as in the Indenture
provided, to execute supplemental indentures adding any provisions to, or
changing in any manner or eliminating any of the provisions of the Indenture or
of any supplemental indenture or modifying in any manner the rights of the
holders of the Securities of all such series; provided, however, that no such
supplemental indenture shall, among other things, (i) change the fixed maturity
of any Security, or reduce the principal amount thereof, or reduce the rate or
extend the time of payment of interest thereon, if any, or reduce any premium
payable on redemption, or make the principal thereof, or premium, if any, or
interest thereon, if any, payable in any coin or currency other than that
hereinabove provided, without the consent of

                                                                               5

the holder of each Security so affected, or (ii) change the place of payment on
any Security, or impair the right to institute suit for payment on any Security,
or reduce the aforesaid percentage of Securities, the holders of which are
required to consent to any such supplemental indenture, without the consent of
the holders of each Security so affected. It is also provided in the Indenture
that, prior to any declaration accelerating the maturity of any series of
Securities, the holders of a majority in aggregate principal amount of the
Securities of such series Outstanding may on behalf of the holders of all the
Securities of such series waive any past default or Event of Default under the
Indenture with respect to such series and its consequences, except a default in
the payment of interest, if any, or the principal of, or premium, if any, on any
of the Securities of such series, or in the payment of any sinking fund
installment or analogous obligation with respect to Securities of such series.
Any such consent or waiver by the Holder of this Security shall be conclusive
and binding upon such Holder and upon all future holders and owners of this
Security and any Securities which may be issued in exchange or substitution
hereof, irrespective of whether or not any notation thereof is made upon this
Security or such other Securities.

                  No reference herein to the Indenture and no provision of this
Security or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal amount with
respect to this Security.

                  The Securities are issuable in denominations of $1,000 and any
whole multiples of $1,000.

                  The Company, the Trustee, and any agent of the Company or of
the Trustee may deem and treat the registered holder (the "Holder") hereof as
the absolute owner of this Security (whether or not this Security shall be
overdue and notwithstanding any notation of ownership or other writing hereon),
for the purpose of receiving payment hereof, or on account hereof, and for all
other purposes and neither the Company nor the Trustee nor any agent of the
Company or of the Trustee shall be affected by any notice to the contrary. All
such payments made to or upon the order of such registered holder shall, to the
extent of the sum or sums paid, effectually satisfy and discharge liability for
moneys payable on this Security.

                  No recourse for the payment of the principal of, premium, if
any, or interest on this Security, or for any claim based hereon or otherwise in
respect hereof, and no recourse under or upon any obligation, covenant or
agreement of the Company in the Indenture or any indenture supplemental thereto
or in any Security, or because of the creation of any indebtedness represented
thereby, shall be had against any incorporator, stockholder, officer or
director, as such, past, present or future, of the Company or of any successor
corporation, either directly or through the Company or any successor
corporation, whether by virtue of any constitution, statute or rule of law or by
the enforcement of any assessment or penalty or otherwise, all such liability
being, by the acceptance hereof and as part of the consideration for the issue
hereof, expressly waived and released.

                  As provided in the Indenture and subject to certain
limitations therein set forth, the transfer of this Security is registrable in
the Security Register, upon surrender of this Security for registration of
transfer at the Corporate Trust Office or agency in a Place of Payment for this
Security, duly endorsed by, or accompanied by a written instrument of transfer
in form

                                                                               6

satisfactory to the Company and the Security Registrar duly executed by, the
Holder hereof or such Holder's attorney duly authorized in writing, and
thereupon one or more new Securities of this series or of like tenor and of
authorized denominations and for the same aggregate principal amount, will be
issued to the designated transferee or transferees.

                  The Company intends to treat, and by purchasing this Security,
the holder agrees to treat, for all tax purposes, this Security as a financial
contract for cash settlement, rather than as a debt instrument.

                  NOW THEREFORE, the Company and the Calculation Agent agree as
follows:

                  1. Appointment of Agent. The Company hereby appoints Lehman

         calculate and announce a Closing Index Level on any date, (c)
         adjustments to the Index, the Successor Index or the Closing Index
         Level if the method of calculating any of these items changes in a
         material respect or if the Index or Successor Index is in any other way
         modified so that it does not, in the opinion of the Calculation Agent,
         fairly represent the value of the Index, or Successor Index, as the
         case may

         to reasonable compensation for all services rendered by it as agreed to
         between the Calculation Agent and the Company.

                  5. Terms and Conditions. The Calculation Agent accepts its
         obligations herein set out upon the terms and conditions hereof,
         including the 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

                                                                               3

         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 Agent, 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 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
         may be merged or converted or any corporation with which the
         Calculation Agent may be consolidated, or any corporation resulting
         from any merger, conversion or consolidation to which the Calculation
         Agent shall be a party, or any corporation to which the Calculation
         Agent shall sell or otherwise transfer all or substantially all of the
         assets and business of 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.

                  7. Certain Definitions. Terms not otherwise defined herein or
         in Annex A hereto are used herein as defined in the Indenture or the
         Securities.

         Agent against any losses or liability which it may incur or sustain in
         connection with its appointment or the exercise of its powers and
         duties hereunder except such as may result from the gross negligence or
         willful misconduct of the Calculation Agent or any of its agents or
         employees.

                                                                               4

                        [Calculation Agency Agreement]

                                     ANNEX A

               1. The Index.

                  The Index is the Russell 2000 Index (the "Index"), as
calculated, published and disseminated by Frank Russell Company ("Russell").

               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 following:

                  o   If the Final Index Level is greater than or equal to the
                      Initial Index Level, the sum of:

                      (1) $1,000; and

                                                    Final Index   Initial Index
                                      Upside          Level     -      Level
                      (2) $1,000 x Participation x  ---------------------------
                                       Rate              Initial Index Level

                  o   If the Final Index Level is less than the Initial Index
                      Level and the Closing Index Level is at or above the
                      Threshold Level on all Exchange Business Days during the
                      Measurement Period, $1,000.

                  o   If the Final Index Level is less than the Initial Index
                      Level and the Closing Index Level has fallen below the
                      Threshold Level on any Exchange Business Day during the
                      Measurement Period, the product of:

                      (1) $1,000; and

                      (2)  Final Index Level
                          -------------------
                          Initial Index Level

                3. Discontinuance of the Index.

                  (a) If Russell discontinues publication of the Index and
Russell or another entity publishes a successor or substitute index (the
"Successor Index") that the Calculation Agent determines, in its sole discretion
exercised in good faith, to be comparable to the discontinued Index, then the
Calculation Agent shall determine the Closing Index Level to be used for
purposes of (a) determining whether the Closing Index Level has fallen below the
threshold level on any Exchange Business Day during the measurement period and
(b) computing the Maturity Payment Amount by reference to the Closing Index
Level of such Successor Index on the date that the Final Index Level is to be
determined.

                                                                               2

                  (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 Russell discontinues publication of the Index and the
Calculation Agent determines that no Successor Index is available at such time,
or if Russell (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 (a) determining whether the Closing Index Level has fallen below the
threshold level on any Exchange Business Day during the measurement period and
(b) computing 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
Index Level (or, if trading in any of the relevant securities has been
materially suspended or materially limited, its good faith estimate of the
Closing Index 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 (or any Successor Index) on the
Relevant Exchange on which such Security trades.

               4. Alteration of Method of Calculation.

                  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
