              NOTES TO UNAUDITED PRO FORMA COMBINED BALANCE SHEET
 
NOTE 1
 
     The Unaudited Pro Forma Combined Balance Sheet has been prepared to reflect
the effect of the Merger as if it occurred on September 30, 1997 for an
aggregate purchase price of $63,948,300 and estimated transaction costs of
approximately $7,800,000. Pro forma adjustments are made to reflect:
 
          (a) The elimination of the equity of ConQuest on acquisition.
 
          (b) The adjustment to allocate the excess purchase price over the fair
     value of ConQuest's net assets at September 30, 1997 to goodwill.
 


                                                                      SEPTEMBER 30, 1997

          Management has not yet allocated any of the excess purchase price to
     identifiable intangible assets such as intellectual property, in-process
     research and development, customer relationships or specific contracts as
     valuations of any potential intangible assets are not currently available.
     Should management identify such assets in the future, the useful life of
     any individual asset may differ from the goodwill amortization period of 20
     years currently reflected in the Pro Forma Combined Statements of
     Operations.
