Item 1.01 Entry into a Material Definitive Agreement.


Acceleration of Vesting of Stock Option Awards


On October 3, 2005, the Compensation Committee of the Board of Directors of Bruker BioSciences Corporation (the “Company”) approved the acceleration of vesting of all unvested options to purchase shares of common stock of the Company that are held by current employees, officers and directors of the Company, which have an exercise price per share equal to or greater than $4.64 (the closing market price of the Company’s common stock on October 3, 2005).  Options to purchase 857,923 shares of common stock are subject to this acceleration, including 132,688 options held by officers and directors of the Company.  Under the accounting for stock options in accordance with Accounting Principles Board Opinion No. 25 “Accounting for Stock Issued to Employees”, and FASB Interpretation No. 44 “Accounting for Certain Transactions Involving Stock Compensation”, the acceleration of the vesting of these options will not result in a compensation charge in the fourth quarter ending December 31, 2005 because the exercise prices of the affected options (which have not changed) is greater than the closing price of the Company’s common stock on October 3, 2005.


Because these options have exercise prices in excess of current market values (are “underwater”), they are not fully achieving their original objectives of incentive compensation and employee retention. The Company believes that the acceleration of these underwater options may have a positive effect on employee morale and retention.  The acceleration also reduces future compensation expense that the Company would otherwise recognize in its consolidated statement of operations with respect to these options once the Statement of Financial Accounting Standards No. 123 (revised 2004) “Share-Based Payment”, issued by the Financial Accounting Standards Board, becomes effective for reporting periods beginning in January 2006.  Management has estimated the pre-tax charge to be eliminated from future accounting periods beginning in January 2006 amounts to approximately $3.7 million over the original remaining vesting periods of the affected options.






Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
