This adjustment reflects sales of Interpore 200 material for the periods presented had they been invoiced at the prices provided for in the distribution agreement with Steri-Oss. b) In connection with the Transaction, personnel that were directly associated with the dental business were separated from the Company. The elimination of these ongoing costs are reflected in the columns titled "Less dental business." In addition, personnel reductions were made in other parts of the Company not directly associated with the dental business because of reduced operations following the Transaction. This adjustment reflects the savings which would have resulted had these personnel reductions occurred as of the beginning of the periods presented. c) Reflects incremental interest income at 5% on approximately $662,000 in net cash proceeds ($1.5 million received from Steri-Oss on May 1, 1997, less an estimated $838,000 in transaction costs including employee separation payments, broker commission, consulting agreements and other legal and administrative fees) resulting from the sale of the dental business. d) Reflects net cash proceeds of approximately $662,000 resulting from the sale of the dental business (see Note c). e) Reflects the deferred payment, estimated at $749,000, to be received from Steri-Oss in January 1998 in connection with the sale of the dental business. f) Reflects an estimated loss on the sale of the dental business of $700,000. 7 8 SIGNATURE 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.
