          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 wilful misconduct.

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

successor Calculation Agent.


                                                                               3

          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,

          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

          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.

     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

                                                   By:__________________________
                                                          Name:   Oliver Budde
                                                          Title:  Vice President





                                     ANNEX A

1.       10 Uncommon Values Index.


         Each year, the Investment Policy Committee of Lehman Brothers Inc.,
with the assistance of its Equity Research Department, selects a portfolio of 10
common stocks or other equity securities that it believes are attractive
investments over the year for which they are chosen (the "10 Uncommon Values").

         The "10 Uncommon Values Index" represents an equal dollar-weighted
portfolio of the common stocks or other equity securities of the ten companies
underlying the 10 Uncommon Values for each Twelve-Month Period during the period
beginning on the date of announcement of the 10 Uncommon Values in 2002 and
ending on the Stated Maturity, as adjusted by certain extraordinary corporate
events involving the issuers of the Index Securities as described herein. The
announcement of the ten common stocks that shall make up the 10 Uncommon Values
Index shall be made on or about July 1 (such date of announcement, the
"Announcement Day") of each year preceding the initial issuance of and during
the term of the Securities. Except as set forth below, the Index Securities in
the 10 Uncommon Values Index shall remain constant for each Twelve-Month Period.

2.       Determination of the Maturity Payment Amount.


         The Calculation Agent shall determine the Ending Index Level and the
Maturity Payment Amount payable for each Security.

         The amount payable at Stated Maturity for each $1,000 principal amount
of Securities (the "Maturity Payment Amount") shall be the following:

         If the Ending Index Level of the 10 Uncommon Values Index is greater
than or equal to 100 (the index level of the 10 Uncommon Values Index on June
27, 2002), the lesser of:

(1)      $1,190; and

(2)      $1,000  x  Ending Index Level
                           100

         If the Ending Index Level of the 10 Uncommon Values Index is less than
100, the lesser of:

(1)       $1,000; and

(2)      $1,000  x  Ending Index Level
                                80

3.       Determination of the Rollover Closing Level of the 10 Uncommon Values
Index.

         The Calculation Agent shall determine the Rollover Closing Level of the
10 Uncommon Values Index for each Twelve-Month Period after the Close of Trading
on the Trading Date prior

                                      A-1



to each  Announcement  Day (the "Rollover  Determination  Date").  The "Rollover
Closing Level" shall equal the sum of (a) the sum of the products of the Closing
Prices and the applicable  Multipliers  for each Index Security and (b) the Cash
Included in the 10 Uncommon Values Index at the Closing of Trading, in each case
on the Rollover  Determination  Date.  The Rollover  Closing Level shall then be
assumed to be used to buy, on the ensuing Announcement Day, equal dollar amounts
of the ten common stocks that shall  initially be the Index  Securities  for the
next Twelve-Month Period at each Index Security's Average Execution Price.

4.       Multipliers.


         The Multiplier relating to each Index Security is the number of shares
(including fractional shares, expressed as a decimal) of such Index Security
included in the 10 Uncommon Values Index. The Multipliers shall be determined by
the Calculation Agent and shall be based on each Index Security's Average
Execution Price. The number of shares of an Index Security constituting the
"Multiplier" for such Index Security shall equal the number of shares (or
fraction of one share) of such Index Security that, when multiplied by the
Average Execution Price for such Index Security, results in the Index Security
initially accounting on the Announcement Day for 10% of the level of 10 Uncommon
Values Index on an equal dollar-weighted basis. The Multipliers with respect to
each Index Security shall remain constant for the Twelve-Month Period that such
Index Security is part of the 10 Uncommon Values Index unless adjusted for
certain extraordinary corporate events as described below. Each Multiplier shall
be rounded at the Calculation Agent's discretion.

5.       Adjustments to the Multipliers and the 10 Uncommon Values Index.


         Adjustments to a Multiplier and the 10 Uncommon Values Index shall be
made in the following circumstances. For purposes of these adjustments, except
as noted below, American Depository Receipts ("ADRs") are treated like common
stock if a comparable adjustment to the foreign shares underlying the ADRs is
made pursuant to the terms of the depository agreement for the ADRs or if the
holders of ADRs are entitled to receive property in respect of the underlying
foreign share.

(a) If an Index Security is subject to a stock split or reverse stock split,
then once the split has become effective, the Multiplier relating to the Index
Security shall be adjusted. The Multiplier shall be adjusted to equal the
product of the number of shares outstanding of the Index Security after the
split with respect to each share of such Index Security immediately prior to
effectiveness of the split and the prior Multiplier.

(b) If an Index Security is subject to an extraordinary stock dividend or
extraordinary stock distribution that is given equally to all holders of shares,
then once the Index Security is trading ex-dividend, the Multiplier for such
Index Security shall be increased by the product of the number of shares of such
Index Security issued with respect to one share of such Index Security and the
prior Multiplier.

(c) If the issuer of an Index Security, or if an Index Security is an ADR, the
issuer of the underlying foreign share is being liquidated or dissolved or is
subject to a proceeding under

                                      A-2



any applicable bankruptcy,  insolvency or other similar law, such Index Security
shall  continue to be included  in the 10 Uncommon  Values  Index so long as the
primary  exchange,  trading system or market is reporting a market price for the
Index  Security.  If a  market  price,  including  a price on a  bulletin  board
service,  is no longer  available for an Index  Security,  then the value of the
Index Security shall equal zero for so long as no market price is available, and
no attempt  shall be made to find a  replacement  stock or increase the level of
the 10  Uncommon  Values  Index to  compensate  for the  deletion  of such Index
Security.

(d) If the issuer of an Index Security, or if an Index Security is an ADR, the
issuer of the underlying foreign share, has been subject to a merger or
consolidation and is not the surviving entity and holders of the Index Security
are entitled to receive cash, securities, other property or a combination
thereof in exchange for the Index Security, then the following shall be included
in the 10 Uncommon Values Index:

(i)  To the extent cash is received,  the 10 Uncommon Values Index shall include
     the amount of the cash  consideration  at the time  holders are entitled to
     receive the cash  consideration  (the "M&A Cash  Component"),  plus accrued
     interest.  Interest  shall accrue  beginning the first London  Business Day
     after the day that holders are  entitled to receive the cash  consideration
     until the next  Announcement Day (the "M&A Cash Component  Interest Accrual
     Period").  Interest  shall accrue on the M&A Cash Component at a rate equal
     to the London Interbank Offered Rate ("LIBOR") with a term corresponding to
     the M&A Cash Component Interest Accrual Period.

(ii) To the  extent  that  equity  securities  that are  traded  or listed on an
     exchange,  trading system or market are received, once the exchange for the
     new  securities  has become  effective,  the former Index Security shall be
     removed from the 10 Uncommon  Values  Index and the new  security  shall be
     added  to the  10  Uncommon  Values  Index  as a new  Index  Security.  The
     Multiplier  for the new Index  Security shall equal the product of the last
     value of the  Multiplier of the original  Index  Security and the number of
     securities of the new Index Security exchanged with respect to one share of
     the original Index Security.

(iii)To the extent  that equity  securities  that are not traded or listed on an
     exchange,  trading  system  or  market or  non-equity  securities  or other
     property  (other  than cash) are  received,  the  Calculation  Agent  shall
     determine  the "Fair  Market  Value" of the  securities  or other  property
     received based on the Average Execution Price. The 10 Uncommon Values Index
     shall  include an amount of cash equal to the product of the  Multiplier of
     the Index  Security and the Fair Market  Value (the "M&A Sale  Component").
     The 10 Uncommon Values Index shall also include accrued interest on the M&A
     Sale Component.  Interest shall accrue  beginning the first London Business
     Day after the day that an affiliate  of Holdings  sells the  securities  or
     other  property used to hedge  Holdings'  obligations  under the Securities
     until the next  Announcement Day (the "M&A Sale Component  Interest Accrual
     Period").  Interest  shall  accrue  at a rate  equal to  LIBOR  with a term
     corresponding to the M&A Sale Component Interest Accrual Period.

                                      A-3



(e) If all of an Index Security of an issuer is converted into or exchanged for
the same or a different number of shares of any class or classes of common stock
other than the Index Security, whether by capital reorganization,
recapitalization or reclassification or otherwise, then, once the conversion has
become effective, the former Index Security shall be removed from the 10
Uncommon Values Index and the new common stock shall be added to the 10 Uncommon
Values Index as a new Index Security. The Multiplier for each new Index Security
shall equal the product of the last value of the Multiplier of the original
Index Security and the number of shares of the new Index Security issued with
respect to one share of the original Index Security.

(f) If the issuer of an Index Security issues to all of its shareholders common
stock or another equity security that is traded or listed on an exchange,
trading system or market of an issuer other than itself, then the new common
stock or other equity security shall be added to the 10 Uncommon Values Index as
a new Index Security. The multiplier for the new Index Security shall equal the
product of the last value of the Multiplier with respect to the original Index
Security and the number of shares of the new Index Security with respect to one
share of the original Index Security.

(g) If an ADR is no longer listed or admitted to trading on a United States
securities exchange or trading system registered under the Securities Exchange
Act or is no longer a security quoted on the NASDAQ Stock Market, Inc. then the
foreign share underlying the ADR shall be deemed added to the 10 Uncommon Values
Index as a new Index Security. The initial Multiplier for that new Index
Security shall equal the last value of the Multiplier for the ADR multiplied by
the number of underlying foreign shares represented by a single ADR.

(h) If an Index Security is subject to an extraordinary dividend or an
extraordinary distribution, including upon liquidation or dissolution, of cash,
equity securities that are not traded or listed on an exchange, trading system
or market, non-equity securities or other property of any kind which is received
equally by all holders of such Index Security, then the 10 Uncommon Values Index
shall include the following:

     (i)  To the extent cash is entitled to be received,  the 10 Uncommon Values
          Index shall include on each day after the time that the Index Security
          trades  ex-dividend until the date the cash  consideration is entitled
          to be  received,  the  present  value  of  the  cash  to be  received,
          discounted at a rate equal to LIBOR,  with a term  beginning  that day
          and ending on the date that the cash is entitled  to be received  (the
          "PV  Extraordinary  Cash Component").  When the cash  consideration is
          received, the PV Extraordinary Cash Component will be deleted from the
          10  Uncommon  Values  Index and the 10  Uncommon  Values  Index  shall
          include the amount of the cash consideration (the  "Extraordinary Cash
          Component"),  plus  accrued  interest.  Interest  shall  accrue on the
          Extraordinary  Cash Component  beginning the first London Business Day
          after the day that holders are  entitled to receive the  Extraordinary
          Cash Component  until the next  Announcement  Day (the  "Extraordinary
          Cash Component  Interest Accrual Period").  Interest shall accrue at a
          rate equal to LIBOR  with a term  corresponding  to the  Extraordinary
          Cash Component Interest Accrual Period.

                                      A-4



     (ii) To the extent that equity  securities that are not traded or listed on
          an exchange,  trading  system or market or  non-equity  securities  or
          other property (other than cash) is received,  the  Calculation  Agent
          shall  determine  the fair  market  value of the  securities  or other
          property  received  based on the  Average  Execution  Price and the 10
          Uncommon  Values  Index  shall  include an amount of cash equal to the
          product of the  Multiplier  of the Index  Security and the fair market
          value (the  "Extraordinary  Sale  Component").  The 10 Uncommon Values
          Index shall also include accrued  interest on the  Extraordinary  Sale
          Component.  Interest shall accrue  beginning the first London Business
          Day after the day that an affiliate of Holdings  sells the  securities
          or  other  property  used to hedge  Holdings'  obligations  under  the
          Securities until the next  Announcement Day (the  "Extraordinary  Sale
          Component  Interest Accrual Period").  Interest shall accrue at a rate
          equal  to  LIBOR  with  a term  corresponding  to  Extraordinary  Sale
          Component Interest Accrual Period.

     (iii)If similar  corporate  events  occur with  respect to the issuer of an
          equity  security  other than  common  stock that is included in the 10
          Uncommon Values Index,  adjustments  similar to the above will be made
          for that equity security.

         The payment of an ordinary cash dividend by an issuer of an Index
Security from current income or retained earnings shall not result in an
adjustment to the Multiplier.

         No adjustments of any Multiplier of an Index Security shall be required
unless the adjustment would require a change of at least .1% (.001) in the
Multiplier then in effect. The Multiplier resulting from any of the adjustments
specified above shall be rounded at the Calculation Agent's discretion.

6.       Determination of Daily Level of the 10 Uncommon Values.


         If the AMEX is unable to obtain certain information necessary for its
daily calculation and dissemination of the level of the 10 Uncommon Values
Index, the Calculation Agent shall provide the necessary information as follows
below.

         In order to determine the value of an Index Security that is listed on
a non-United States exchange, trading system or market (the "Foreign Value"),
the Calculation Agent shall, once per Trading Day, value the Index Security
using the most recent sales price of such Index Security available from the
primary exchange, trading system or market in the Index Security's home market,
quoted as of the Close of Trading.

          In  order  to  convert  the  Foreign  Value  into  U.S.  dollars,  the
Calculation Agent shall use the Official W.M. Reuters Spot Closing Rate. If
there are several  quotes for the Official W.M.  Reuters Spot Closing Rate,
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  Foreign  Value shall be
determined  using the last available U.S.  dollar  cross-rate  quote before
11:00 A.M., New York City time.

                                      A-5



         In order to determine the value of an Index Security that is listed or
quoted on a bulletin board service, the Calculation Agent shall use the average
of the midpoint of the bid and ask prices provided by three market makers in
that Index Security. The Calculation Agent shall obtain the bid and ask prices
promptly upon the opening of trading on that Trading Day at 9:30 A.M., New York
City time or at such other time as the Calculation Agent determines.

         The Calculation Agent shall provide AMEX with the value of the M&A Cash
Component, the M&A Sale Component, the PV Extraordinary Cash Component, the
Extraordinary Cash Component and the Extraordinary Sale Component as soon as
such values are available. The Calculation Agent shall, once per Trading Day,
provide AMEX with the interest accrued on the Cash Included in the 10 Uncommon
Values Index.

         be determined using the Closing Price for such Index Security on the
         next preceding Trading Day on which a Market Disruption Event did not
         occur. Once the Market Disruption Event has ceased, the Closing Price
         of such Index Security shall then be adjusted to equal the Average
         Execution Price of the Index Security. The Rollover Closing Level and

               Index  Security has occurred on that day, in each 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 such Index Security is traded
               or, in the case of an Index  Security not listed or quoted in the

               the  one-half  hour  period  preceding  the Close of  Trading  in
               options  contracts  related  to such Index  Security,  whether by
               reason of movements  in price  exceeding  levels  permitted by an
               exchange,   trading  system  or  market  on  which  such  options
               contracts are traded or otherwise.

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

               preceding  the Close of  Trading,  of accurate  price,  volume or
               related  information  in  respect of such  Index  Security  or in
               respect of options contracts  related to such Index Security,  in
               each case traded on any major U.S.  exchange or trading system or
               in the case of Index Securities of a non-U.S. issuer, the primary

occurred:

          (i)  a limitation  on the hours or number of days of trading shall not
               constitute  a  Market  Disruption  Event  if it  results  from an
               announced  change in the regular  business  hours of the relevant
               exchange, trading system or market;

          (ii) any  suspension  in trading in an  options  contract  on an Index
               Security by a major securities exchange, trading system or market
               by  reason of (a) a price  change  violating  limits  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
