Independent Auditors' Consent
The Board of Directors
Teltech Resource Network Corporation:
We consent to the use of our report dated March 3, 2000, except for note 15,
which is as of March 6, 2000, with respect to the balance sheets of Teltech
Resource Network Corporation (the Company) as of December 31, 1998 and 1999, and
the related statements of operations, stockholders' deficit, and cash flows for
the years then ended, which report appears in the Form F-4 of Sopheon plc and to
the reference to our firm under the heading "Experts" in the Form F-4.
Our report contains an emphasis paragraph that states that the Company was
obligated to offer to redeem one-half of the redeemable convertible preferred
stock on August 31, 1999 and to offer to redeem all shares each succeeding
August 31 through 2004. The Company has been advised by outside legal counsel
that under Minnesota law, it is not currently obligated to make such an offer as
management believes sufficient funds are not available to make such a redemption
at this time.
