Cash Investment Strategy

 - $90 to $100 million in capital expenditures to support strategic
    growth plan
 - $50 to $60 million for selected acquisitions (core, esoteric or
    anatomic pathology labs)
 - Share repurchases - new $250 million stock repurchase program
 - Retain flexibility in utilizing remaining cash

 - Revenue growth of approximately 5% to 7% compared to 2003,
   including small acquisitions and/or new contracts
 - EBITDA margins of approximately 25% of sales

 - Net interest expense of approximately $36 million
 - Tax rate of 41%

* Free cash flow is defined as operating cash flow, minus capital expenditures.

  income tax credits of approximately $50 million.
