This amendment provides additional information with respect to the performance goals and potential costs of the employee incentive plans described below. Item 1.01. Entry into a Material Definitive Agreement Item 5.02. Compensatory Arrangements of Certain Officers Establishment of Performance Goals for Annual and Long-Term Incentive Plans Awards under both the Company's annual bonus plan and the long-term retention program, including the long-term incentive plan ("LTIP"), are issued under the Company's 2001 Equity Incentive Plan (the "Plan"). The Compensation Committee of the Company's Board of Directors (the "Committee") is responsible for establishing performance goals for the annual bonus plan and LTIP performance periods. A. 2007 Annual Bonus Plan At its meeting on December 6, 2006, the Committee determined amounts that may be paid to executive officers and certain senior management members of the Company based on the achievement of varying levels of operating performance during fiscal year 2007. The Committee established three specific levels of operating margin percentage as the thresholds for payment. The awards would be paid in cash following completion of the 2007 audited financial statements showing the level of operating performance achieved, if the minimum threshold level or a higher performance level is achieved. The aggregate amount payable to all participants if the minimum threshold performance level is achieved is approximately $1.5 million; if the middle threshold performance level is achieved is approximately $3.0 million; and if the maximum threshold level is achieved is approximately $4.6 million. The potential ranges of payment under this plan for each of the executive officers is as follows: Andrew Baker, Chairman and CEO* $302,000 - $906,000 Brian Cass, President and Managing Director* $302,000 - $906,000 Richard Michaelson, CFO $75,000 - $225,000 Julian Griffiths, Director of Operations* $75,500 - $226,500 Mark Bibi, Secretary and General Counsel $75,000 - $225,000 * Payments to Messrs. Baker, Cass and Griffiths are made in UK pounds sterling. For purposes of estimating these payments in US dollars, an exchange rate of (pound)1.00 = $1.83 has been used. B. Long-Term Retention Program In order to encourage valuable members of the management team to remain with the Company over the next three years, the Committee has adopted a long-term retention program that contains two elements: the LTIP and the grant of equity. 1. 2007 LTIP At its meeting on December 6, 2006, the Committee determined amounts that may be paid to executive officers and certain senior management members of the Company in respect of LTIP awards for the three-year 2007-2009 performance period. The Committee established a specified level of operating margin percentage to be achieved over any four consecutive quarters during such performance period that would trigger the payment of the awards. This threshold level of operating margin percentage is higher than the maximum level of operating margin percentage under the 2007 Bonus Plan. The awards would be paid in cash following confirmation by the Company's independent auditor that the threshold performance level had been achieved. The aggregate amount payable to all participants under the 2007 LTIP if the threshold performance level is achieved is approximately $5 million. The potential payments under this plan for each of the executive officers is as follows: Andrew Baker, Chairman and CEO* $1,208,000 Brian Cass, President and Managing Director* $1,208,000 Richard Michaelson, CFO $480,000 Julian Griffiths, Director of Operations* $483,000 Mark Bibi, Secretary and General Counsel $360,000 * Payments to Messrs. Baker, Cass and Griffiths are made in UK pounds sterling. For purposes of estimating these payments in US dollars, an exchange rate of (pound)1.00 = $1.83 has been used. 2. Senior Management Stock Options/Stock Grants At its meeting on December 6, 2006, the Committee (a) authorized the reservation of an additional 750,000 shares of common stock for issuance under the Plan and (b) approved the grant under the Plan to members of senior management of LSR of stock options to acquire an aggregate of 480,000 shares of Common Stock, including the following grants to executive officers: options to acquire 100,000 shares to Andrew Baker, Chairman and CEO; options to acquire 100,000 shares to Brian Cass, President and Managing Director; options to acquire 50,000 shares to Julian Griffiths, Director of Operations; and options to acquire 100,000 shares to Mark Bibi, General Counsel and Secretary of LSR. The exercise price of such options was $9.95 per share, the average daily high price for the five trading days ending on the date of the December 6 Compensation Committee meeting. Such options vest one half on December 31, 2008 and one half on December 31, 2009. The Committee also approved at that meeting the grant of 50,000 shares of Common Stock to each of Richard Michaelson, CFO and Mark Bibi, General Counsel and Secretary.
