Lehman Brothers Holdings Inc. (the “Registrant”) is not timely filing its Quarterly Report on Form 10-Q for the fiscal quarter ended February 28, 2011 (“Form 10-Q”). The principal reasons for the Registrant’s inability to file at this time are as follows: (1) the filing by the Registrant of a voluntary petition for relief under Chapter 11 of the United States Code (the “Bankruptcy Code”) in the United States Bankruptcy Court for the Southern District of New York (the “Court”) on September 15, 2008 in a jointly administered proceeding named In re Lehman Brothers Holdings Inc., et. al. under Case Number 08-13555; (2) the commencement of various administrative or civil rehabilitation proceedings of subsidiaries comprising significant parts of the Registrant’s European and Asian businesses; (3) the sale since September 15, 2008 of significant businesses comprising the Registrant’s historical business; and (4) the completion on May 4, 2009 of the transfer to Neuberger Berman Group LLC of the Registrant's investment management business, as described in its Current Report on 8-K filed with the Commission on May 4, 2009. As a result of these developments, the Registrant is currently unable to complete the preparation of its consolidated financial statements for such period in as much as it currently has neither access to major components of its internal systems nor the ability to prepare its consolidated financial statements and the remainder of the report, with all the required disclosures, to have them properly certified by its current executive officers, and have them reviewed by its independent auditors. The Registrant will not be in a position to file by the fifth calendar day following the required filing date, April 14, 2011, as prescribed in Rule 12b-25.

(2) Have all other periodic reports required under Section 13 or 15(d) of the Securities Exchange Act of 1934 or Section 30 of the Investment Company Act of 1940 during the preceding 12 months or for such shorter period that the registrant was required to file such report(s) been filed? If answer is no, identify report(s).

The Registrant has not filed its Quarterly Reports for the fiscal quarters ended August 31, 2008, February 28, 2009, May 31, 2009, August 31, 2009, February 28, 2010, May 31, 2010 and August 31, 2010 and has not filed its Annual Report for the fiscal years ended November 30, 2008, November 30, 2009 and November 30, 2010.

(3) Is it anticipated that any significant change in results of operations for the corresponding period for the last fiscal year will be reflected by the earnings statements to be included in the subject report or portion thereof?

If so: attach an explanation of the anticipated change, both narratively and quantitatively, and, if appropriate, state the reasons why a reasonable estimate of the results cannot be made.

The Registrant anticipates, based on the information currently available to it, that results of operations for the First Quarter ended February 28, 2011 will be significantly different from those for the corresponding period for the last fiscal year, due to significant developments in the business over the past year. The Registrant issued quarterly reports on Form 10-Q on April 9, 2008 and July 10, 2008, for the quarterly periods ended February 29, 2008 and May 31, 2008, respectively, and a current report on Form 8-K on September 10, 2008 containing certain preliminary information relating to its earnings for the quarterly period ended August 31, 2008. Additionally, on January 14, 2009, November 18, 2009, September 22, 2010 and January 13, 2011 the Registrant filed current reports on Form 8-K containing a status report on the Registrant’s bankruptcy proceedings, which includes certain financial information relating to periods since the commencement of the Registrant’s bankruptcy proceedings on September 15, 2008. Additionally, on January 30, 2009, March 10, 2009, April 13, 2009, May 20, 2009, June 4, 2009, June 15, 2009, July 8, 2009, August 21, 2009, September 16, 2009, October 14, 2009, November 13, 2009, December 14, 2009, January 14, 2010, February 19, 2010, March 17, 2010, March 29, 2010, April 16, 2010, April 19, 2010, April 22, 2010, May 3, 2010, May 20, 2010, June 23, 2010, July 22, 2010, August 13, 2010, September 17, 2010,
