     WHEREAS, the Company has authorized the issuance of up to $1,380,000
aggregate principal amount of Absolute Buffer Notes Due August 3, 2010, Linked
to a Basket of Four Stock Indices (the "Securities")*;

     WHEREAS, the Securities will be issued under an Indenture, dated as of

services described herein in connection with the Securities;

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

     1. Appointment of Agent. The Company hereby appoints Lehman Brothers Inc.,
as Calculation Agent, and Lehman Brothers Inc. hereby accepts such appointment
as the Company's agent for the purpose of performing the services hereinafter
described upon the terms and subject to the conditions hereinafter mentioned.

     2. Calculations and Information Provided. In response to a request made by
the Trustee for a determination of the Maturity Payment Amount due on the Stated
Maturity Date of the Securities, the Calculation Agent shall determine such
Maturity Payment Amount and notify the Trustee of its determination. The
Calculation Agent shall also determine (a) the Successor Index if publication of
a Component Index is discontinued, (b) the Multiplier and Weight of each
remaining Component Index if no Successor Index is available or if the publisher
of such Component Index or Successor Index, as the case may be, fails to
calculate and publish a Closing Index Level on any date, (c) adjustments to a

method of calculating any of these items changes in a material respect or if a
Component Index or Successor Index is in any other way modified so that

----------

*    Each Component Index is a trademark of the sponsor of such Component Index
     and has been licensed for use by Lehman Brothers Holdings Inc. The
     Securities, linked to the performance of the Component Indices, are not
     sponsored, endorsed, sold or promoted by the sponsors of the Component
     Indices and the sponsors of the Component Indices make no representation
     regarding the advisability of investing in the Securities.



                                                                               2

it does not, in the opinion of the Calculation Agent, fairly represent the level
of such Component Index, or Successor Index, as the case may be, had such
changes or modifications not been made, (d) adjustments to the Threshold Level,
if required in order to reflect adjustments made in a Component Index or
Successor Index and (e) whether a Market Disruption Event has occurred. The
Calculation Agent shall notify the Trustee of all such adjustments or any such
Successor Index, or if a Market Disruption Event has occurred. Annex A hereto
sets forth the procedures the Calculation Agent will use to determine the
information described in this Section 2.

     3. Calculations. Any calculation or determination by the Calculation Agent
pursuant hereto shall (in the absence of manifest error) be final and binding.

     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



                                                                               3

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.

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.

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.

                         [Calculation Agency Agreement]



                                     ANNEX A
                                     -------

1.   The Basket and the Component Indices.


     The basket (the "Basket") shall initially be composed of the following
indices: the Dow Jones EURO STOXX 50(SM) Index, as calculated, published and
disseminated by STOXX Limited, the FTSE 100 Index(TM), as calculated, published
and disseminated by FTSE International Limited, the Nikkei 225(SM) Index, as
calculated, published and disseminated by Nihon Keizai Shimbun, Inc., and the
S&P(R)/ASX 200 Index, as calculated, published and disseminated by the Standard
& Poor's Australian Index Committee (each, a "Component Index" and,
collectively, the "Component Indices").

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 Basket Return is zero or positive, $1,000 + ($1,000 x the
         Upside Participation Rate x the Final Basket Return).

     o   If the Final Basket Return is negative and the Final Basket Level is
         equal to or greater than the Threshold Level, $1,000 + ($1,000 x the
         absolute value of the Final Basket Return).

     o   If the Final Basket Return is negative and the Final Basket Level is
         less than the Threshold Level, $1,000 + ($1,000 x the Final Basket
         Return).

3.   Discontinuance of the Index.

     (a) If a publisher of a Component Index discontinues publication of such
Component Index and such publisher or another entity publishes a successor or
substitute index (a "Successor Index") that the Calculation Agent determines, in
its sole discretion exercised in good faith, to be comparable to the
discontinued Component Index, then the Calculation Agent shall determine each
subsequent Closing Basket Level to be used in computing 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 a publisher of a Component Index discontinues publication of such
Component Index and the Calculation Agent determines that no Successor Index is
available at such time, or if such publisher (or the publisher of any Successor
Index to such Component Index) fails to calculate and publish a Closing Index
Level for such Component Index (or a Successor Index) on any date when it would
ordinarily do so in accordance with its customary practice, the Component Index
(or Successor Index) shall be removed from the Basket as of the close of



                                                                               2

business on the last day on which its Closing Index Level was published by its
publisher and the Weight of each remaining Component Index (or Successor Index)
shall simultaneously be increased (by adjusting the respective Multipliers) by
an amount determined by the Calculation Agent such as to result in both (a) the
relative Weights of remaining Component Indices on such day and (b) the Closing
Basket Level on such day remaining unchanged. In addition, the Calculation Agent
shall make such other adjustments to the terms of the Securities as may be
required to account for such discontinued Component Index.

4.   Alteration of Method of Calculation.

     If at any time the method of calculating a Component Index, any Successor
Index, or the Closing Index Level thereof on any particular day is changed in a
material respect, or if a Component Index or any 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 such Component Index or such Successor
Index had such changes or modifications not been made, then, from and after such
time, the Calculation Agent shall, at the Close of Trading of the Relevant
Exchanges on which the securities comprising such Component Index or such
Successor Index traded on any date the Closing Index Level thereof 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 such Component Index or such Successor
Index, as the case may be, as if such changes or modifications had not been
made. The Calculation Agent shall calculate the Closing Index Level of a
Component Index on any particular day and the Maturity Payment Amount with
reference to such Component Index or such Successor Index, as adjusted.

     Accordingly, if the method of calculating a Component 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, then the Calculation Agent shall adjust
such index in order to arrive at a level of such Component Index or such
Successor Index as if it had not been modified.
