Because these notes are part of a series of Lehman Brothers Holdings' debt

              EXAMPLES OF AMOUNT PAYABLE AT MATURITY OR REPURCHASE

Here are two examples of hypothetical alternative redemption amount
calculations. In each of these examples it is assumed that Cisco Systems, Inc.
does not pay any cash dividends on its shares of common stock during the term of
the notes.

EXAMPLE 1. ASSUMING THE SETTLEMENT VALUE IS $15.00:

Alternative redemption amount per $1,000 note =

                       $15.00
    $1,000    x    --------------    =   $714.75
                      $20.9861


As a result, on the stated maturity date, you would receive $1,000, plus accrued
but unpaid interest, per $1,000 note because $1,000 is greater than $714.75.

In the case of stock settlement on the stated maturity date or upon repurchase
in this example, you would receive, if you held a $1,000 note, 66 shares of
common stock of Cisco Systems, Inc. plus $10.00 in cash, plus accrued but unpaid
interest, at maturity, or 47 shares of common stock of Cisco Systems, Inc. plus
$9.75 in cash, plus accrued but unpaid interest, upon repurchase. To the extent
that you hold more than $1,000 aggregate principal amount of notes, the
calculations of cash payments in lieu of fractional shares would be made on an
aggregate, rather than on a per $1,000 note, basis. For example, if you held
$14,000,000 aggregate principal amount of notes, you would receive, in total,
933,333 shares of common stock of Cisco Systems, Inc. plus $5.00 in cash, plus
accrued but unpaid interest, at maturity, or 667,100 shares of common stock of
Cisco Systems, Inc. plus $0.00 in cash, plus accrued but unpaid interest, upon
repurchase.

EXAMPLE 2. ASSUMING THE SETTLEMENT VALUE IS $30.00:

Alternative redemption amount per $1,000 note =

                      $30.00
    $1,000    x    ------------    =   $1,429.51
                     $20.9861


As a result, on the stated maturity date, you would receive $1,429.51, plus
accrued but unpaid interest, per $1,000 note because $1,429.51 is greater than
$1,000.

In the case of stock settlement on the stated maturity date or upon repurchase
in this example, you would receive, if you held a $1,000 note, 47 shares of
common stock of Cisco Systems, Inc. plus $19.51 in cash, plus accrued but unpaid
interest, at maturity or upon repurchase. To the extent that you hold more than
$1,000 aggregate principal amount of notes, the calculations of cash payments in
lieu of fractional shares would be made on an aggregate, rather than on a per
$1,000 note, basis. For example, if you held $14,000,000 aggregate principal
amount of notes, you would receive, in total, 667,104 shares of common stock of
Cisco Systems, Inc. plus $20.00 in cash, plus accrued but unpaid interest, at
maturity or upon repurchase.

To the extent the actual settlement value differs from the values assumed above
or that Cisco Systems, Inc. begins to pay cash dividends, the results indicated
above would be different.

(1)  This figure reflects the threshold value.

The above figures are for purposes of illustration only. The actual amount
received by investors and the resulting total and pre-tax rates of return will
depend entirely on the actual settlement value determined by the calculation
agent. In particular, the actual settlement value could be lower or higher than
those reflected in the table.

The table above only provides hypothetical return information with regard to
notes held to maturity. It is not applicable in the case of notes repurchased
prior to the stated maturity date.

You should compare the features of the notes to other available investments
before deciding to purchase the notes. Due to the uncertainty as to whether the
alternative redemption amount, at stated maturity or in connection with a
repurchase, will be greater than $1,000 per $1,000 note, the return on
investment with respect to the notes may be higher or lower than the return
available on other securities issued by Lehman Brothers Holdings or by others
and available through Lehman Brothers Inc. You should reach an investment
decision only after carefully considering the suitability of the notes in light
of your particular circumstances.

           SUPPLEMENTAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

Lehman Brothers Holdings is required to provide the comparable yield to you and,
solely for tax purposes, is also required to provide a projected payment
schedule that includes the actual interest payments on the notes and estimates
the amount and timing of contingent payments on the notes. Lehman Brothers
Holdings will not determine the actual comparable yield of the notes until they
are issued. You can obtain the comparable yield of the notes and the projected
payment schedule by submitting a written request for them to Lehman Brothers
Holdings at the following address:

Controller's Office
Lehman Brothers Holdings Inc.
745 Seventh Avenue
New York, New York 10019
(212) 526-7000

Lehman Brothers Holdings agrees and, by purchasing a note, you agree, for United
States federal income tax purposes, to be bound by Lehman Brothers Holdings'
determination of the comparable yield and projected payment schedule. As a
consequence, for United States federal income tax purposes, you must use the
comparable yield determined by Lehman Brothers Holdings and the projected
payments set forth in the projected payment schedule prepared by Lehman Brothers
Holdings in determining your interest accruals, and the adjustments thereto, in
respect of the notes.

                        SUPPLEMENTAL PLAN OF DISTRIBUTION

Lehman Brothers Holdings has agreed to sell to Lehman Brothers Inc. and Lehman
Brothers Inc. has agreed to purchase, all of the notes at the price indicated on
the cover of this pricing supplement.

Lehman Brothers Holdings has agreed to indemnify Lehman Brothers Inc. against
liabilities, including liabilities under the Securities Act of 1933, as amended,
or to contribute to payments that Lehman Brothers Inc. may be required to make
relating to these liabilities as described in the MTN prospectus supplement and
the base prospectus.

Lehman Brothers Inc. will offer the notes initially at a public offering price
equal to the issue price set forth on the cover of this pricing supplement.
After the initial public offering, the public offering price may from time to
time be varied by Lehman Brothers Inc.

Lehman Brothers Holdings has granted to Lehman Brothers Inc. an option to
purchase, at any time within 13 days of the original issuance of the notes, up
to $2,100,000 additional aggregate principal amount of notes solely to cover
over-allotments. To the extent that the option is exercised, Lehman Brothers
Inc. will be committed, subject to certain conditions, to purchase the
additional notes. If this option is exercised in full, the total public offering
price, the underwriting discount and proceeds to Lehman Brothers Holdings would
be $16,100,000, $40,250 and $16,059,750, respectively.

Lehman Brothers Holdings expects to deliver the notes against payment on or
about August 9, 2006, which is the fifth business day following the date of this
pricing supplement.

Under Rule 15c6-1 of the Exchange Act, trades in the secondary market generally
are required to settle in three business days, unless the parties to any such
trade expressly agree otherwise. Accordingly, if any purchaser wishes to trade
the notes on the date of this pricing supplement, it will be required, by virtue
of the fact that the notes initially will settle on the fifth business day
following the date of this pricing supplement, to specify an alternate
settlement cycle at the time of any such trade to prevent a failed settlement.

Lehman Brothers Holdings or an affiliate has entered into swap agreements or
related hedge transactions with one of Lehman Brothers Holdings' other
affiliates or unaffiliated counterparties in connection with the sale of the
notes and Lehman Brothers Inc. and/or an affiliate has earned additional income
as a result of payments pursuant to the swap, or related hedge transactions.
