Item 5.02       Compensatory Arrangements of Certain Officers.

On February 26, 2007, the Compensation Committee of the Board of Directors (the “Committee”) of Genzyme Corporation (“Genzyme”) determined 2006 incentive bonuses for Genzyme’s executive officers.  Prior to the beginning of 2006, the Committee had established a bonus target for each executive officer.

For each of the executive officers, the bonus target includes both a corporate performance component and an individual performance component, which components are weighted on an individual basis. The corporate performance component is payable based on the extent to which Genzyme achieves the operating income goals approved by the Board of Directors in connection with setting the 2006 annual budget. The current corporate performance bonus formula allows for 100% payment when 100% of the target is met. If the performance target is exceeded, for every 1% above the target, 2.5% is added to the bonus payment, up to a maximum of 150% payment for achievement of 120% or more of the target. If the performance target is not met, for every 1% below the target, 1.5% is reduced from the bonus payment. No corporate bonus is paid if less than 86% of the target is met.  For 2006, Genzyme exceeded the operating income goals by 1% and, in accordance with the formula, the Committee awarded the corporate performance component at 102.5% of target.  The Committee also evaluated the individual performance of each of the executive officers.  The Committee awarded the individual performance component at 100% to 105% of target.  For 2006, the Committee awarded aggregate total bonuses ranging from 101.5% to 103.1% of target.

The 2006 base salaries and incentive bonuses for Genzyme’s named executive officers are listed in Exhibit 10.1, and are incorporated herein by reference.  Additional information regarding compensation of executive officers will be included in Genzyme’s proxy statement to be filed in connection with its Annual Meeting of Shareholders to be held on May 24, 2007.
