RISK FACTORS

An investment in the notes entails certain risks not associated with an investment in conventional floating rate or fixed rate medium-term notes. See “Risk Factors” in the Prospectus Supplement.

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

We intend to treat the Notes as variable rate debt instruments, as described under “Supplemental United States Federal Income Tax Consequences—Variable Rate Debt Instruments” in the Prospectus Supplement.

We intend to take the position that a noteholder should include interest payments in income as they are received or accrued in accordance with such noteholder’s method of accounting for tax purposes. However, noteholders should consult their own tax advisors regarding the tax treatment of the notes, including the effect of the Survivor’s Option.

HISTORICAL LEVELS OF 6-MONTH LIBOR

The following table, showing the historical level of 6m USD LIBOR_REF in effect on the Trade Date and on the hypothetical Interest Payment Dates listed below, the Interest Rate per Annum payable on any Interest Payment Date for the Notes, however, will be determined based on 6m USD LIBOR_REF in effect on each day during the related Interest Period. The historical experience of 6m USD LIBOR_REF should not be taken as an indication of the future performance of 6m USD LIBOR_REF during the term of the Notes. Fluctuations in the level of 6m USD LIBOR_REF make the Notes’ effective Interest Rate per Annum difficult to predict and can result in an effective Interest Rate per Annum to investors that are lower than anticipated. In addition, historical interest rates are not necessarily indicative of future interest rates. Fluctuations in interest rates and interest rate trends that have occurred in the past are not necessarily indicative of fluctuations that may occur in the future, which may be wider or narrower than those that have occurred historically.

DESCRIPTION OF SURVIVOR’S OPTION

Upon request by the authorized representative of the beneficial owner of the notes, Lehman Brothers Holdings Inc. will repay those notes prior to the Maturity Date following the death of the beneficial owner of the notes (the ‘‘Survivor’s Option’’), provided such notes were acquired by the deceased beneficial owner at least six months prior to the date of the request. Upon the valid exercise of the Survivor’s Option and the proper tender of the note for repayment, Lehman Brothers Holdings Inc. will repay that note, in whole or in part, at a price equal to 100% of the principal amount of the deceased beneficial owner’s beneficial interest in the note plus accrued and unpaid interest to the date of repayment. For purposes of this section, a beneficial owner of a note is a person who has the right, immediately prior to such person’s death, to receive the proceeds from the disposition of that note, as well as the right to receive payment of the principal of the note.

To be valid, the Survivor’s Option must be exercised by or on behalf of the person who has authority to act on behalf of the deceased beneficial owner of the note under the laws of the applicable jurisdiction (including, without limitation, the personal representative of or the executor of the estate of the deceased beneficial owner or the surviving joint owner with the deceased beneficial owner).

The death of a person holding a beneficial ownership interest in a note having the Survivor’s Option: (1) with any person in a joint tenancy with right of survivorship; or (2) with his or her spouse in tenancy by the entirety, tenancy in common, as community property or in any other joint ownership arrangement, will be deemed the death of a beneficial owner of that note, and the entire principal amount of the note held in this manner will be subject to repayment by Lehman Brothers Holdings Inc. upon request. However, the death of a person holding a beneficial ownership interest in a note as tenant in common with a person other than his or her spouse will be deemed the death of a beneficial owner only with respect to such deceased person’s interest in the note, and only the deceased beneficial owner’s percentage interest in the principal amount of the note will be subject to repayment.

If the ownership interest in a note having the Survivor’s Option is held by a nominee for a beneficial owner or by a custodian under a Uniform Gifts to Minors Act or Uniform Transfer to Minors Act, or by a trustee of a trust that is wholly revocable by the beneficial owner, or by a guardian or committee for a beneficial owner, the death of the beneficial owner of that note will constitute death of the beneficial owner for purposes of the Survivor’s Option, if the beneficial ownership interest can be established to the satisfaction of the trustee. In these cases, the death of the nominee, custodian, trustee, guardian or committee will not be deemed the death of the beneficial owner of such note for purposes of the Survivor’s Option.

Lehman Brothers Holdings Inc. has the discretionary right to limit the aggregate principal amount of Medium-Term Notes, Series I, without regard to series or tranches, as to which exercises of the Survivor’s Option will be accepted by it from all authorized representatives of deceased beneficial owners in any calendar year, to an amount equal to the greater of $1,000,000 or 1.0% of the aggregate amount of all Medium-Term Notes, Series I, that include a Survivor’s Option, without regard to series or tranches, outstanding as of the end of the most recent calendar year.

Lehman Brothers Holdings Inc. also has the discretionary right to limit to $125,000 the aggregate principal amount of Medium-Term Notes, Series I, that include a Survivor’s Option, without regard to series or tranches, as to which exercises of the Survivor’s Option will be accepted by Lehman

Brothers Holdings Inc. from the authorized representative for any individual deceased beneficial owner of such notes in any calendar year. In addition, Lehman Brothers Holdings Inc. will not permit the exercise of the Survivor’s Option (a) for a principal amount less than $1,000, or (b) if such exercise will result in a beneficial ownership interest in a note with a principal amount of less than $1,000 outstanding.

An otherwise valid election to exercise the Survivor’s Option may not be withdrawn. Elections to exercise the Survivor’s Option will be accepted in the order that they are received by the trustee, except for any election the acceptance of which would contravene any of the limitations described above. Notes accepted for repayment through the exercise of the Survivor’s Option will be repaid on the first interest payment date that occurs 20 or more calendar days after the date of the acceptance. Each tendered note that is not accepted in any calendar year due to the application of any of the limitations described in the preceding paragraph will be deemed to be tendered in the following calendar year in the order in which all such notes were originally tendered. If a note tendered through a valid exercise of the Survivor’s Option is not accepted, the trustee will deliver a notice to the registered holder that states the reason that note has not been accepted for repayment.

Because the notes will be issued in book-entry form (except in very limited circumstances), DTC or its nominee will be treated as the holder of the notes, will be the only entity that receives notices from the trustee and, on behalf of the deceased beneficial owner’s authorized representative, will be the only entity that can exercise the Survivor’s Option for such notes. To obtain repayment of a note pursuant to exercise of the Survivor’s Option, the deceased beneficial owner’s authorized representative must provide the following items to the broker or other entity through which the beneficial interest in the note is held by the deceased beneficial owner:

· appropriate evidence satisfactory to the trustee that:

(1) the deceased was the beneficial owner of the note at the time of death and his or her interest in the note was acquired by the deceased beneficial owner at least six months prior to the request for repayment,

(2) the death of the beneficial owner has occurred and the date of death, and

(3) the representative has authority to act on behalf of the deceased beneficial owner;

· if the beneficial interest in the note is held by a nominee or trustee of, custodian for, or other person in a similar capacity to, the deceased beneficial owner, evidence satisfactory to the trustee from the nominee, trustee, custodian or similar person attesting to the deceased’s beneficial ownership of that note;

· a written request for repayment signed by the authorized representative of the deceased beneficial owner with the signature guaranteed by a firm that is a participant in the Security Transfer Agents Medallion Program, the New York Stock Exchange Medallion Signature Program or the Stock Exchange Medallion Program (generally a member of a registered national securities exchange, a member of the National Association of Securities Dealers, Inc., or a commercial bank or trust company having an office in the United States);

· tax waivers and any other instruments or documents that the trustee reasonably requires in order to establish the validity of the beneficial ownership of the note and the claimant’s entitlement to payment; and

· any additional information the trustee requires to evidence satisfaction of any conditions to the exercise of the Survivor’s Option or to document beneficial ownership or authority to make the election and to cause the repayment of the note.

In turn, the broker or other entity will deliver each of these items, through the appropriate direct participant in DTC and the facilities of DTC, to the trustee and will certify to the trustee that the broker or other entity represents the deceased beneficial owner. The broker or other entity will be responsible for disbursing payments received from the trustee, through the facilities of DTC, to the authorized representative.

Lehman Brothers Holdings Inc. retains the right to limit the aggregate principal amount of Medium-Term Notes, Series I, that include a Survivor’s Option, as to which exercises of the Survivor’s Option will be accepted from all authorized representatives of deceased beneficial owners and from the authorized representative for any individual deceased beneficial owner in any one calendar year as described above. All other questions regarding the eligibility or validity of any exercise of the Survivor’s Option generally will be determined by the trustee, in its sole discretion, which determination will be final and binding on all parties.

Forms for the exercise of the Survivor’s Option may be obtained from Citibank, N.A., 111 Wall Street, 15th Floor, New York, NY 10043, Attention: Agency and Trust Group, telephone: (800) 422-2066.

SUPPLEMENTAL INFORMATION CONCERNING THE PLAN OF DISTRIBUTION

Lehman Brothers Holdings has agreed to sell to Lehman Brothers Inc. (the “Agent”), and the Agent has agreed to purchase from Lehman Brothers Holdings Inc. the principal amount of the Notes at the price specified on the cover of this pricing supplement. The Agent is committed to take and pay for all of the Notes, if any are taken.

The Agent proposes to offer the Notes initially at a public offering price equal to the Issue Price set forth above, and may also use all or a portion of its commissions on the Notes to pay selling concessions or fees to other dealers not to exceed 3.00%. It is expected that delivery of the Notes will be made against payment therefor more than three business days following the date of this pricing supplement. 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, purchasers who wish to trade the securities on any day prior to the third business day before the settlement date will be required to specify an alternative settlement cycle at the time of any such trade to prevent failed settlement.

If the Notes are sold in a market-making transaction after their initial sale, information about the purchase price and the date of the sale will be provided in a separate confirmation of sale.
