                          Bear Extendible Notes (BENs)

      The floating rate Bear Extendible Notes described in this Pricing
Supplement, which we refer to as the BENs, will mature on the initial maturity
date, unless the maturity of all or any portion of the principal amount of the
BENs is extended in accordance with the procedures described below. In no event
will the maturity of the BENs be extended beyond the final maturity date.

      During the notice period for each election date, you may elect to extend
the maturity of all or any portion of the principal amount of your BENs so that
the maturity of your BENs will be extended to the date occurring 2 years from
and including the 15th day of the next succeeding month. However, if that 2 year
extension date is not a Business Day, the maturity of your BENs will be extended
to the immediately preceding Business Day. The election dates will be the 15th
calendar day of each March and September from September 2006 to March 2009
inclusive, whether or not any such day is a Business Day.

      You may elect to extend the maturity of all of your BENs or of any portion
thereof having a principal amount of $25,000 or any multiple of $1,000 in excess
thereof. To make your election effective on any election date, you must deliver
a notice of election during the notice period for that election date. The notice
period for each election date will begin on the 5th Business Day prior to the
election date and end on the election date; however, if that election date is
not a Business Day, the notice period will be extended to the following Business
Day. Your notice of election must be delivered to the Trustee for the BENs,
through the normal clearing system channels described in more detail below, no
later than the last Business Day of the notice period. Upon delivery to the
Trustee of a notice of election to extend the maturity of the BENs or any
portion thereof during a notice period, that election will be revocable during
each day of such notice period, until 12:00 noon (New York City time) on the
last Business Day in such notice period, at which time such notice will become
irrevocable.

      If on any election date you do not make an election to extend the maturity
of all or any portion of the principal amount of your BENs, the principal amount
of the BENs for which you have failed to make such an election will become due
and payable on the initial maturity date, or any later date to which the
maturity of your BENs has previously been extended. The principal amount of the
BENs for which such election is not exercised will be represented by a note
issued on such election date. The new note so issued will have the same terms as
the BENs, except that it will not be extendible, will have a separate CUSIP
number and its maturity date will be the date that is 2 years from and
including such election date or, if such 2 year extension date is not a Business
Day, the immediately preceding Business Day. The failure to elect to extend the
maturity of all or any portion of the BENs will be irrevocable and will be
binding upon any subsequent holder of such BENs.

      The BENs will bear interest from the date of issuance until the principal
amount thereof is paid or made available for payment at a rate determined for
each Interest Reset Period by reference to the Interest Rate Basis, based on the
Index Maturity, plus the applicable Spread for the relevant Interest Reset Date.
We describe how floating rates are determined and calculated in the section
captioned "Description of Notes - Floating Rate Notes" in the Prospectus
Supplement, subject to and as modified by the provisions described below.

                                                        (continued on next page)

                            Bear, Stearns & Co. Inc.



      The BENs will be issued in registered global form and will remain on
deposit with The Depository Trust Company ("DTC"), as depositary for the BENs.
Therefore, you must exercise the option to extend the maturity of your BENs
through DTC. To ensure that DTC will receive timely notice of your election to
extend the maturity of all or a portion of your BENs, so that it can deliver
notice of your election to the Trustee prior to the close of business on the
last Business Day in the notice period, you must instruct the direct or indirect
participant through which you hold an interest in the BENs to notify DTC of your
election to extend the maturity of your BENs in accordance with the then
applicable operating procedures of DTC. Notice of any decision to revoke your
election must be made through the same clearing system channels.

      DTC must receive any notice of election from its participants no later
than 12:00 noon (New York City time) on the last Business Day in the notice
period for any election date. Different firms have different deadlines for
accepting instructions from their customers. You should consult the direct or
indirect participant through which you hold an interest in the BENs to ascertain
the deadline for ensuring that timely notice will be delivered to DTC. If the
election date is not a Business Day, notice of your election to extend the
maturity date of your BENs must be delivered to DTC by its participants no later
than 12:00 noon (New York City time) on the first Business Day following the
election date.

      The BENs will initially be limited to $102,000,000 in aggregate principal
amount. We may create and issue additional floating rate extendible notes with
the same terms as the BENs so that such additional floating rate extendible
notes will be combined with this initial issuance of BENs.

      For purposes of your exercise of an election to extend the maturity of all
or any portion of your BENs, "Business Day" means any day that is not a Saturday
or Sunday, and that is neither a legal holiday nor a day on which banking
institutions or trust companies in New York City are authorized or obligated by
law to close.

                  CERTAIN US FEDERAL INCOME TAX CONSIDERATIONS

    The following discussion summarizes certain US federal income tax
consequences of the purchase, beneficial ownership and disposition of the BENs.
This discussion supplements the section captioned "Certain US Federal Income Tax
Considerations" in the Prospectus Supplement dated February 2, 2005. This
summary deals only with a beneficial owner of BENs that is:

o   an individual who is a citizen or a resident of the United States for U.S.
    federal income tax purposes;

o   a corporation (or other entity that is treated as a corporation for U.S.
    federal tax purposes) that is created or organized in or under the laws of
    the United States or any State thereof (including the District of Columbia);

o   an estate whose income is subject to U.S. federal income taxation regardless
    of its source; or

o   a trust if a court within the United States is able to exercise primary
    supervision over its administration, and one or more United States persons,
    as defined for U.S. federal income tax purposes, have the authority to
    control all of its substantial decisions (each a "U.S. holder").

    An individual may, subject to certain exceptions, be deemed to be a resident
of the United States by reason of being present in the United States for at
least 31 days in the calendar year and for an aggregate of at least 183 days
during a three-year period ending in the current calendar year (counting for
such purposes all of the days present in the current year, one-third of the days
present in the immediately preceding year, and one-sixth of the days present in
the second preceding year).

    This summary is based on interpretations of the Internal Revenue Code of
1986, as amended (the "Code"), regulations issued thereunder, and rulings and
decisions currently in effect (or in some cases proposed), all of which are
subject to change. Any such change may be applied retroactively and may
adversely affect the U.S. federal income tax consequences described herein. This
summary addresses only U.S. holders that purchase BENs at initial issuance and
beneficially own such BENs as capital assets and not as part of a "straddle,"
"hedge," "synthetic security" or a "conversion transaction" for U.S. federal
income tax purposes, or as part of some other integrated investment. This
summary does not discuss all of the tax consequences that may be relevant to
particular investors or to investors subject to special treatment under the U.S.
federal income tax laws (such as banks, thrifts, or other financial
institutions; insurance companies; securities dealers or brokers, or traders in
securities electing mark-to-market treatment; mutual funds or real estate
investment trusts; small business investment companies; S corporations;
investors that hold their BENs through a partnership or other entity treated as
a partnership for U.S. federal tax purposes; investors whose functional currency
is not the U.S. dollar; certain former citizens or residents of the United
States; persons subject to the alternative minimum tax; retirement plans or
other tax-exempt entities, or persons holding the BENs in tax-deferred or
tax-advantaged accounts; or "controlled foreign corporations" or a "passive
foreign investment companies" for U.S. federal income tax purposes). This
summary also does not address the tax consequences to shareholders, or other
equity holders in, or beneficiaries of, a holder of BENs, or any state, local or
foreign tax consequences of the purchase, ownership or disposition of the BENs.

PROSPECTIVE PURCHASERS OF BENS SHOULD CONSULT THEIR TAX ADVISORS AS TO THE U.S.

CONSEQUENCES ARISING UNDER THE LAWS OF ANY OTHER TAXING JURISDICTION TO WHICH
THEY MAY BE SUBJECT.

U.S. Federal Income Tax Treatment of U.S. Holders.

General

      There are no regulations, rulings or other authorities addressing the U.S.
federal income tax treatment of debt instruments with terms that are
substantially similar to the BENs, and therefore the U.S. federal income tax
treatment of the BENs is subject to some uncertainty. As discussed below, we
intend to take the position that the election by a U.S. holder to extend the
maturity of BENs through the Final Maturity Date will not be a taxable event for
us or the U.S. holder, and we intend to take the position that the Final
Maturity Date is the maturity date of the BENs for U.S. federal income tax
purposes. However, this position is not free from doubt.

Tax Treatment of the BENs

      Under the Treasury regulations governing original issue discount on debt
instruments (the "OID Regulations"), for purposes of determining the yield and
maturity of a debt instrument, a U.S. holder is generally deemed to exercise an
option or combination of options if the exercise would maximize the yield on the
debt instrument. Because the Spread will periodically increase during the term
of the BENs, for purposes of the OID Regulations, as of the issue date, we
intend to take the position that U.S. holders should be deemed to elect on each
election date, through and including March 15, 2009, to extend the maturity of
the BENs through the Final Maturity Date, and therefore that the Final Maturity
Date is the maturity date of the BENs for U.S. federal income tax purposes.

      Under the Treasury regulations governing modifications to the terms of
debt instruments (the "Modification Regulations"), the exercise of an option by
a U.S. holder of a debt instrument to defer any scheduled payment of principal
is a taxable event if, based on all the facts and circumstances, the deferral is
considered material under the Modification Regulations. The Modification
Regulations do not specifically address the unique features of the BENs
(including their economic equivalence to a five-year debt instrument containing
put options).

      Because we will take the position under the OID Regulations that the Final
Maturity Date is the maturity date of the BENs, we intend to take the position
that the election by a U.S. holder to extend the maturity of BENs through the
Final Maturity Date will not give rise to a taxable event for us or U.S.
holders. U.S. holders, by purchasing the BENs, will agree to this treatment and
will agree not to take a contrary position for U.S. federal income tax purposes
unless required by law.

      It is unclear how the OID Regulations apply in conjunction with the
Modification Regulations, and therefore no assurance can be given that the IRS
will accept, or that the courts will uphold, this position. For example, the IRS
may assert that a U.S. holder should not be treated as exercising all options
that maximize its yield for purposes of the Modification Regulations, and
therefore each extension of BENs may be treated as a modification for U.S.
federal income tax purposes. Under a safe harbor in the Modification
Regulations, a deferral that extends the maturity of a debt instrument for the
lesser of five years or 50% of the original term of the debt instrument does not
give rise to a taxable event. Because the BENs mature pursuant to their terms in
two years, an election to extend the maturity of BENs through March 2009 (i.e.,
50% of two years) should not be treated as a taxable event in any case. However,
the IRS may

                                      -6-



view any election to extend the maturity of the BENs by more than one year as
giving rise to a taxable event.

      In this event, a U.S. holder would generally be required to recognize any
gain inherent in the BENs. We do not expect that any such gain would be
significant (but the amount of any such gain recognized will depend upon all the
facts and circumstances present at the time of the taxable event).

      In addition, it is possible that the IRS could assert that the BENs are
subject to special rules governing "contingent payment debt instruments." If the
IRS were successful in this assertion, U.S. holders may be required to accrue
original issue discount income, subject to adjustments, at a "comparable yield"
on the issue price of the BENs and any gain recognized with respect to the BENs
generally would be treated as ordinary income. However, because the BENs bear a
variable interest rate that is reset periodically throughout the term of the
BENs and provide for current payment of interest, we expect that the adverse tax
consequences of such treatment, if any, should not be significant. The U.S.
federal income tax treatment of contingent payment debt instruments is
summarized in the Prospectus Supplement dated February 2, 2005 under the caption
"Certain US Federal Income Tax Considerations - Contingent Payment Debt
Instruments." Each U.S. holder is urged to consult its tax advisors regarding
its tax treatment in the event it elects to extend the maturity of the BENs.

      The remainder of this summary assumes that the Final Maturity Date is the
maturity date of the BENs, elections to extend the maturity of all or a portion
of the principal amount of the BENs through the Final Maturity Date will not be
taxable events and that the BENs are not contingent payment debt instruments for
U.S. federal income tax purposes.

Interest

      Interest  paid to a U.S.  holder on the BENs will be includible in gross
income as ordinary  interest  income when paid or accrued in  accordance  with
the U.S. holder's usual method of accounting.

      In addition, any increase on a particular Interest Reset Date in the
Spread that is added to LIBOR to determine the interest rate for the ensuing
interest period for the BENs should be considered "de minimis" under the
original issue discount rules, and therefore the BENs should not be considered
to have original issue discount for U.S. federal income tax purposes as a result
of the increase in the Spread.

Sale, Exchange, Redemption, Repayment or Other Disposition of the BENs

      Upon the disposition of BENs by sale, exchange, redemption, repayment or
other disposition, a U.S. holder will generally recognize taxable gain or loss
equal to the difference, if any, between (i) the amount realized on the
disposition (other than amounts attributable to accrued but unpaid interest,
which would be treated as such) and (ii) the U.S. holder's adjusted tax basis in
the BENs. A U.S. holder's adjusted tax basis in a BEN will generally equal the
cost of the BEN to the U.S. holder. Capital gains of individual taxpayers from
the sale, exchange, redemption, repayment or other disposition of BENs held for
more than one year may be eligible for reduced rates of taxation. The
deductibility of a capital loss realized on the sale, exchange, redemption,
repayment or other disposition of a BEN is subject to limitations.

Information Reporting and Backup Withholding.

      Information reporting will apply to certain payments on BENs (including
interest and OID) and proceeds of the sale of BENs held by a U.S. holder that is
not an exempt recipient (such as a corporation). Backup withholding may apply to
payments made to a U.S. holder if (a) the U.S. holder has failed to provide its
correct taxpayer identification number on IRS Form W-9, or (b) we have been
notified by the IRS of an underreporting by the U.S. holder (underreporting
generally refers to a determination by the IRS that a payee has failed to
include in income on its tax return any reportable dividend and interest
payments required to be shown on a tax return for a taxable year).

      Backup withholding is not an additional tax and may be refunded (or
credited against your U.S. federal income tax liability, if any), provided, that
certain required information is furnished. The information reporting
requirements may apply regardless of whether withholding is required.

THE PRECEDING DISCUSSION IS ONLY A SUMMARY OF CERTAIN OF THE TAX IMPLICATIONS OF
AN INVESTMENT IN BENS. PROSPECTIVE PURCHASERS ARE URGED TO CONSULT WITH THEIR
TAX ADVISORS PRIOR TO INVESTING TO DETERMINE THE TAX IMPLICATIONS OF SUCH
INVESTMENT IN LIGHT OF EACH SUCH INVESTOR'S PARTICULAR CIRCUMSTANCES.
