     percent  from the same period last year, when the company reported revenues
     of  $11.5  million.

- -    Cash  usage  for  the  quarter  was reduced to $ (459,000), better than the

Revenues  for  the fourth fiscal quarter ended June 30, 2003 were $11.8 million,

intangible  assets. The company is still in the process of completing its annual
impairment  test  of  goodwill  and  purchased  intangibles  and  estimates  the
impairment  charge  to  be  between $7.0 - $12.0 million. This would result in a
revised net loss for the quarter ended June 30, 2003 of between $(16.7) million,
or $(0.30) per share and $(21.7) million, or $(0.39) per share. Net loss for the
same  period last year included an impairment charge of $57.3 million. The final
results  of  the annual impairment test for the quarter ended June 30, 2003 will

share  in fiscal 2002. Net loss for the year ended June 30, 2003 included a $0.9
million  impairment charge for purchased intangible assets. The company is still
in  the  process  of  completing  its  annual  impairment  test  of goodwill and
purchased  intangibles  and estimates the impairment charge to be between $7.0 -
$12.0  million.  This would result in a revised net loss for the year ended June
30,  2003  of between $(45.2) million, or $(0.83) per share and $(50.2) million,
or $(0.92) per share.  Net loss for the fiscal year ended June 30, 2002 included
an  impairment  charge  of  $57.3 million. Additionally, net loss for the fiscal
year  ended  June  30,  2002  included the cumulative effective of an accounting
change  in  the  amount  of $5.9 million related to the adoption of Statement of
Financial  Accounting Standards No. 142, "Goodwill and Other Intangible Assets."

During  the  fourth quarter, cash and cash equivalents and marketable securities
decreased  approximately  $(459,000), compared with a decrease of $(5.5) million
for  the  third  quarter  ended  March  31,  2003.

 "Our  focus  during  this  past  year  was on establishing a strong operational
foundation  and  strategic plan that would stabilize the company and establish a
base  for  achieving  growth  in fiscal 2004," said Marc Nussbaum, president and
chief  executive  officer.  "During  the  past  four quarters, we simplified our
business  model  and infrastructure, brought expenses in line with revenues, and
reduced  our  cash  burn.  At  the  same  time,  we  improved  key  operational
fundamentals  of the business and continued to invest in the necessary research,
product  development,  marketing  and  sales  initiatives."

FISCAL  2004  OUTLOOK


"Moving  into  fiscal  2004,  our focus continues to be on managing our expenses
closely  while  investing in programs to drive top-line growth. Now that we have
stabilized  our  cash  burn,  our mission will be to further solidify our strong
position  and  drive  penetration  in  the machine-to-machine pervasive Internet
space,"  Nussbaum  said.
