             Among Latest Organisations to Select Sopheon Software             

MINNEAPOLIS and LONDON─June 25, 2008 ─ Sopheon, the international provider of
software and services for product lifecycle management, announced today that
150 customers have now licensed its software products. Recent signees include
Novartis, the world's fifth-largest pharmaceutical company, Burger King Corp.,
the second largest fast-food hamburger chain in the world with more than 11,400
restaurants in all 50 U.S. states and 70 countries and U.S. territories, and
the U.S. Army. Sopheon entered 2008 with 135 licensees.

Recent orders have continued to add to the company's already promising
performance outlook for 2008. Earlier this month, in a statement to attendees
of its annual general meeting for shareholders, Sopheon announced that revenue
visibility for the full year 2008 already stood at £5.7 million. Based on
business activity since the meeting, such visibility has now increased to more
than £6 million. Visibility at any point in time comprises revenue expected
from (i) closed license orders, including those which are contracted but
conditional on acceptance decisions scheduled later in the year; (ii)
contracted services business delivered or expected to be delivered in the year;
and (iii) recurring maintenance, hosting and rental streams. The visibility
calculation does not include revenues from new sales opportunities expected to
close during the remainder of 2008. The company's pipeline of such prospective
business remains very active. Sopheon's revenues for all of 2007 totaled £6.3
million.

"Today's milestone punctuates a historic pattern of substantial growth," said
Barry Mence, chairman of Sopheon's board of directors. "Since 2001, reported
revenues from our core business have increased by an average of 41% in U.S.
dollars annually. This record has been achieved despite periods of economic
uncertainty and escalating competition. Our success obviously reflects the
appeal of our solutions and their benefits. But it is also rooted in the
quality of our people, and the passion and dedication that they bring to every
aspect of our effort to deliver exceptional value to our customers. I couldn't
be more proud of what they have accomplished."
