Lehman Brothers 2007 Annual Meeting of Stockholders: Amendment to the 2005 Stock Incentive Plan March 30, 2007

Proposal 3 – Amendment to the 2005 Stock Incentive Plan The stockholders of Lehman Brothers Holdings Inc. (“the Firm”) approved the 2005 Stock Incentive Plan (2005 SIP) in April 2005. At that time, stockholders were advised that the 2005 SIP was expected to cover stock-based awards for fiscal years 2005 and 2006. The Firm currently has only 7.5 million shares available for future grant. These remaining shares are insufficient to cover employee stock-based awards for fiscal 2007 under the Firm’s current compensation framework. The Board of Directors has approved an amendment (the “Plan Amendment”) to the Firm’s 2005 SIP, subject to approval by the Firm’s stockholders at the 2007 Annual Meeting, that would increase the number of shares eligible for grant by 75 million shares, which represents approximately 14% of the Firm’s common shares outstanding. With these additional shares, the Firm expects to have sufficient shares to cover stock-based awards for fiscal years 2007 and 2008. The Firm expects to request additional shares at the 2009 Annual Meeting of Stockholders. If the Plan Amendment is not approved by stockholders, the Firm would likely be forced to deliver nearly all compensation in cash, losing the benefits of aligning the interests of employees with stockholders. This alignment ultimately serves to create value for all of the Firm’s stockholders. The Board of Directors unanimously recommends a vote FOR approval of the Plan Amendment 1

Features and Benefits of Lehman Brothers Equity Award Program A key element of the Firm’s compensation philosophy is to deliver a portion of employees’ total compensation in the form of restricted stock units (“RSUs”) and in some cases, stock options, in lieu of all-cash compensation. Approximately 98% of the value of equity awards granted as part of 2006 performance compensation were made to employees other than named executive officers. The Firm’s stock-based compensation program is a significant component of annual total compensation, rather than an “add-on” award. For bonus-eligible employees, equity awards are granted as part of a year-end, performance-based bonus. Equity awards generally range from 1% to 50% of an employee’s total compensation, with the amount of compensation in equity increasing as total compensation rises. Bonus-eligible employees who are not awarded a year-end performance bonus do not receive an equity award. For Managing Directors, 35% of RSUs awarded vest after 3 years from the grant date, and 65% vest after 5 years from the grant date. The RSUs do not convert to common stock until 5 years after the grant date. The vesting provisions, combined with the 5-year sales restriction for all RSUs, mean that a Managing Director at Lehman Brothers, on average, holds more than 2 times their annual total compensation in the form of equity at any point in time. This creates a strong incentive for the Firm’s employees to preserve and grow shareholder value. The Firm’s Equity Award Program is also a valuable tool in recruiting new employees to the Firm. If the Plan Amendment is not approved by shareholders, Lehman Brothers would likely be forced to deliver nearly all compensation in cash. The Firm would lose the benefits of directly aligning the interests of employees with stockholders. 2

Stock Repurchase Program Since 1997, the Firm has repurchased a sufficient number of shares to offset the dilution created by the Equity Award Program. The number of shares outstanding has been relatively constant, excluding shares issued in connection with our acquisition of Neuberger Berman in 2003. We believe the repurchase program has prevented shareholder dilution, while allowing the Firm to benefit from the employee commitment generated by broad-based employee share ownership. The Firm has grown book value per share by approximately 19%1 per year on average since 2002, even while repurchasing shares that have offset dilution from stock-based awards and increasing the annual common stock dividend by over 25%2 per year on average. ___________________________ Since 2002, see appendix page 8; the book value per common share calculation includes amortized RSUs granted under employee stock award programs, which have been included in total stockholders’ equity Since 2002, see appendix page 8 3
