Item 2.05. Costs Associated with Exit or Disposal Activities

The following information is filed pursuant to “Item 2.05 Costs Associated with Exit or Disposal Activities,” and amends the Form 8-K filed by the Company on April 20, 2006.

As previously disclosed, on April 19, 2006, the Company decided to discontinue the operations of Nichols Institute Diagnostics (“NID”). The decision to discontinue NID’s operations is expected to result in pretax charges totaling between $32 million and $39 million with $27 million to $29 million to be recorded in the second quarter and the balance to be recorded principally in the third quarter. The charges include the write-off of inventories and impairment of operating assets of $12 million; employee termination benefits of between $5 million and $6 million; various contract termination costs of between $8 million and $12 million, and approximately $7 million to $9 million of costs to support activities to wind-down the business, principally comprised of employee costs and professional fees. The associated cash expenditures before tax benefits are estimated to be between $20 million and $27 million. Approximately $7 million to $10 million of the charges are expected to be non-deductible for tax purposes, resulting in an impact to net income of between $22 million and $27 million.

In the Form 8-K filed on April 20, 2006, the pretax charge related to the decision to discontinue NID’s operations was initially estimated at up to $45 million and the associated cash expenditures were initially estimated at up to $35 million.
