PRICING SUPPLEMENT NO. 224 dated May 30, 2007
to Prospectus Supplement dated May 30, 2006
and Prospectus dated May 30, 2006

LEHMAN BROTHERS HOLDINGS INC.
Medium-Term Notes, Series I

This Pricing Supplement supplements the terms and conditions in, and incorporates by reference, the Prospectus, dated May 30, 2006, as supplemented by the Prospectus Supplement, dated May 30, 2006 (as so supplemented, together with all documents incorporated by reference therein, the “Prospectus”), and should be read in conjunction with the Prospectus. Unless otherwise defined in this Pricing Supplement, terms used herein have the same meanings as are given to them in the Prospectus.

The Notes will mature on June 27, 2008 (the “Initial Maturity Date”), unless the maturity date of all or any portion of the principal amount of the Notes is extended on any Election Date (as defined below) in accordance with the procedures described below. In no event will the maturity date of the Notes be extended beyond June 27, 2013 (the “Final Maturity Date”).

During an Election Notice Period (as defined below) for any Election Date you may elect to extend the maturity of all or any portion of the principal amount of your Notes so that the maturity of your Notes will be extended (as described under “Maturity Extension Option” below).

You may elect to extend the maturity date of all of your Notes or of any portion thereof having a principal amount of $1,000 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 Election Notice Period for that Election Date.  Your notice of extension must be delivered through the normal clearing system channels described in more detail below no later than 12:00 p.m. (New York City time) on the relevant Election Date. Any notice of election to extend the maturity date of the

Notes or any portion thereof will be revocable until 12:00 p.m. (New York City time) on the relevant Election Date, at which time such notice will become irrevocable.

If, with respect to any Election Date, you do not make an election to extend the maturity date of all or any portion of the principal amount of your Notes, the principal amount of the Notes 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 date of your Notes has previously been extended. The principal amount of the Notes for which such election is not exercised will be represented by a note issued on such Election Date. The note so issued will have the same terms as the Notes, except that it will not be extendible, will have separate CUSIP and ISIN numbers and its maturity date will be the date that is the extended maturity date that corresponds to that Election Date, or, if such date is not a Business Day, the next succeeding Business Day. The failure to elect to extend the maturity date of all or any portion of the Notes will be irrevocable and will be binding upon any subsequent holder of such Notes.

The Notes will be issued in registered global form and will remain on deposit with DTC as depository for the Notes. Therefore, you must exercise the option to extend the maturity date of your Notes through DTC. To ensure that DTC will receive timely notice of your election to extend the maturity date of all or a portion of your Notes, 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 Election Notice Period, you must instruct the direct or indirect participant through which you hold an interest in the Notes to notify DTC of your election to extend the maturity date of your Notes in accordance with the then applicable operating procedures of DTC.

DTC must receive any notice of election, or any notice of revocation of a previous election, from its participants no later than 12:00 p.m. (New York City time) on the relevant 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 Notes 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 Notes, or to revoke your election, 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.

CUSIP:	524908ZZ6. In the event that you do not elect to extend the maturity date of all or any portion of your Notes, the principal amount of the Notes for which you do not exercise such election will be assigned a new CUSIP number, as described above.

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.

Although there is no authority directly on point, we intend to treat the Notes as having a term ending on the Final Maturity Date for tax purposes because of a holder’s right to extend the term to such date. Under such treatment, a holder’s election to extend the maturity of the principal amount of the Notes in accordance with the procedures described above would not be a taxable event to such holder for United States federal income tax purposes. Also, even though the spread increases during the term of the Notes, the amount of the increase is de minimis and, therefore, the Notes will not constitute OID notes.

By purchasing the Notes, investors agree to report the United States federal income tax consequences of their ownership of the Notes consistently with the foregoing treatment.

Prospective investors should note that no assurance can be given that the Internal Revenue Service (the “IRS”) will accept, or that the courts will uphold, the characterization and the treatment of the Notes described above. If the IRS were successful in asserting that the term of the Notes ends on the Initial Maturity Date, an election to extend the maturity of the principal amount of the Notes could constitute a taxable event for United States federal income tax purposes, and you would be required to recognize any gain, but not loss, inherent in the Notes at such time upon the exercise of such election. Prospective investors are urged to consult their tax advisors regarding the United States federal income tax consequences of investing in, and extending the maturity of, the Notes.

SUPPLEMENTAL INFORMATION CONCERNING THE PLAN OF DISTRIBUTION

Subject to the terms of a Purchase Agreement between Lehman Brothers Holdings Inc. and Lehman Brothers Inc. and the other agents set forth below (collectively, the “Agents”), Lehman Brothers Holdings Inc. has agreed to sell to the Agents, and each of the Agents has agreed severally to purchase, the principal amounts of Notes set forth opposite its name below:

Agents	Principal Amount of the Notes
Lehman Brothers Inc.	$	2,205,000,000
Banc of America Securities LLC	22,500,000
BNY Capital Markets Inc.	22,500,000
Total	$	2,250,000,000

Under the terms and conditions of the Purchase Agreement, the Agents are committed to take and pay for all of the Notes, if any are taken.  The Agents propose to offer the Notes initially at a public offering price equal to the Issue Price set forth above and may offer the Notes to certain dealers at such price less a concession not in excess of 0.10% of the principal amount of the Notes. The Agents may allow, and the dealers may reallow, a discount not in excess of 0.05% of the principal amount of the Notes on sales to certain other dealers. After the initial public offering, the public offering price and other selling terms may from time to time be varied by the Agents.

Lehman Brothers Holdings will pay certain expenses, expected to be approximately $75,000, associated with the offer and sale of the Notes.

Certain of the Agents and their affiliates have in the past provided, and may in the future from time to time provide, investment banking and/or general financing and/or banking services to Lehman Brothers Holdings and its affiliates, for which they have in the past received, and may in the future receive, customary fees.

Certain of the Agents may not be U.S. registered broker-dealers and accordingly will not effect any sales within the United States except in compliance with applicable U.S. laws and regulations, including the rules of the NASD.

Certain of the Agents may make the securities available for distribution on the Internet through a proprietary website and/or a third-party system operated by Market Axess Corporation, an Internet-based communications technology provider.  Market Axess Corporation is providing the system as a conduit for communications between such Agents and their customers and is not a party to this offering. Market Axess Corporation, a registered broker-dealer, will receive compensation from such Agents based on transactions that such Agents conduct through the system.  Such Agents will make the securities available to their customers through the Internet distributions, whether made through a proprietary or third-party system, on the same terms as distributions made through other channels.

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.
