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.” On April 19, 2006, the Company decided to discontinue NID’s operations. During the fourth quarter of 2005, the Company’s test kit manufacturing subsidiary, NID, instituted its second voluntary product hold within a six-month period, due to quality issues, which has adversely impacted the operating performance of NID. As a result, the Company evaluated a number of strategic options for NID. The decision to discontinue NID’s operations is expected to result in a pretax charge in the second quarter of 2006 preliminarily estimated to be up to $45 million. The estimated charge is expected to principally relate to the write-off of operating assets and the accrual of liabilities associated with employee severance costs and various lease commitments. The associated cash expenditures are estimated to be up to $35 million.

Item 2.06. Material Impairment

The information included in Item 2.05 is hereby incorporated by reference into and filed pursuant to Item 2.06.
