Item 1.01 Entry into a Material Definitive Agreement

On April 22, 2005, Beckman Coulter, Inc. and Agencourt Bioscience Corporation entered into an Agreement and Plan of Merger (the “Agreement”). Agencourt makes products for the life science research market that isolate and purify nucleic acids and operates a service business that isolates and purifies nucleic acids from biological samples The agreement provides for an initial payment of $100 Million at closing and up to $40 Million of contingent payments through 2007 (the “earn out period”). The contingent payments are based on Agencourt achieving specified revenue and operating income targets and on achieving specified schedules for developing and delivering new products. The agreement also requires $7 Million of the initial payment to be put into an escrow account and permits Beckman Coulter to access any earn-out payments that may be due the shareholders for indemnification claims as specified in the Agreement.

The four founders of Agencourt will be offered employment by Beckman Coulter for the duration of the earn-out period. During the earn-out period, termination of any of the four founders without “good cause”, relocation of the existing facility, or transfer of any employees to another Beckman Coulter business or facility without the founders approval will accelerate the payment of the full $40 Million contingent payment. Unvested Agencourt options will be converted into deferred compensation credits that vest in the same manner and at the same time as the original options. The pay out for each such credit on vesting and exercise is equal to the amount the holder would have received had the option been vested and converted into Agencourt shares on the closing date. The cost to Beckman Coulter, if all of these credits mature into obligations to pay, will be $7 Million.

Agencourt has licensed from Harvard and is in the process of developing a technology for the low cost sequencing of the human genome. Agencourt has received an SBIR grant for this development. The license has been placed into a subsidiary, Agencourt Personal Genomics, Inc (“APGI”). Beckman Coulter will acquire 49% of APGI and from the closing to December 31, 2007 will contribute $6 Million to APGI, either in cash or in-kind services. Beckman Coulter also will have certain rights of first offer to be the distributor of products developed by AGPI as well as certain rights to receive a license to any technology developed by AGPI.
