NOTES TO UNAUDITED PRO FORMA CONDENSED STATEMENT OF OPERATIONS FOR THE
TWENTY-SIX WEEKS ENDED SEPTEMBER 27, 2002

(1)   The adjustments include the elimination of WellCheck operations. Sales
      from the Diagnostic Products segment to WellCheck were not eliminated from
      the unaudited pro forma condensed statement of operations because based on
      the terms of the Purchase and Supply Agreement between the Company and
      ImpactHealth, dated December 23, 2002, such sales are expected to
      continue. The sales price between the Company and ImpactHealth is expected
      to continue to approximate the historical inter-segment transfer price to
      WellCheck.

NOTES TO UNAUDITED PRO FORMA CONDENSED STATEMENT OF OPERATIONS FOR THE FISCAL
YEAR ENDED MARCH 29, 2002

(1)   The adjustments include the elimination of WellCheck operations. Sales
      from the Diagnostic Products segment to WellCheck were not eliminated from
      the unaudited pro forma condensed statement of operations because based on
      the terms of the Purchase and Supply Agreement between the Company and
      ImpactHealth, dated December 23, 2002, such sales are expected to
      continue. The sales price between the Company and ImpactHealth is expected
      to continue to approximate the historical inter-segment transfer price to
      WellCheck.
