year ended March 31, 2002 and the nine months ended December 31, 2002 with those
of  Computer  System Products, Inc. (CSP) under the assumptions set forth in the
accompanying  notes. The unaudited pro forma consolidated balance sheet combines
the  APA  and  CSP  balance  sheets as of December 31, 2002 giving effect to the
transaction  as  if the transaction had occurred for the statements of operation
as  of  the  beginning  of  the  periods  presented  and  for  the balance sheet

     The  pro  forma  adjustments  are based upon available information and upon
certain  assumptions  that  management  believes  are  reasonable. The pro forma
financial  statements  and accompanying notes should be read in conjunction with
the  historical  statements  and  the  notes  thereto.

     The  unaudited  pro  forma  condensed consolidated financial statements are
provided  for informational purposes only in response to Securities and Exchange
Commission  ("SEC")  requirements  and  do  not  purport to represent what APA's
financial  position  or  results  of  operations would actually have been if the
transaction  had  in  fact  occurred at such dates or to project APA's financial
position  or  results  of  operations  for  any  future  date  or  period.
