    3rd Quarter Profit & Loss Summary

    The following table summarizes selected information derived from
the condensed consolidated statements of operations for the third
quarters in 2007 and 2006 (in thousands):

                                            2007      2006       %

Cost of Sales                             $  49,869  $ 43,657      14%

Operating Income                          $  10,340  $  4,065     154%
Operating Margin                              13.1%      5.9%

Effective Tax Rate                            48.7%     24.3%

    The cost of sales as a percentage of sales was consistent with
last year and includes $1.1 million of inventory step-up amortization
related to the Enpath acquisition. Excluding this amortization, our
cost of sales percentage improved to 61.7% as we continue to benefit
from our various manufacturing initiatives.

    The increase in SG&A percentage is primarily due to the inclusion
of Enpath operations for the full quarter.

    The increase in net RD&E expenses is primarily due to a planned
increase in spending on new development programs.

    The other operating expense in the current quarter consists of:

- -- Columbia closure/relocations $ 1.0 million
- -- ECP building expansion $ 0.1 million
- -- Asset dispositions and other $ 0.2 million

    As a result of $13.8 million of the in-process research and
development write-off not being deductible for tax purposes, the
effective tax rate for 2007 is now expected to be approximately 48%.
