SOPHEON PLC                                  

              SUPPLEMENT TO PRELIMINARY RESULTS - EQUITY POSITION              

Sopheon plc ('Sopheon') in accordance with the requirements of the Euronext
Amsterdam, confirms that the net liabilities of £1.9m at 31 December 2003
stated on the balance sheet published in its preliminary results announcement
of earlier today, constitutes a negative equity position of £1.9m. Sopheon also
confirms that to the board's knowledge, this matter does not impact on the
group's credit facilities. The position is arrived at after deducting the
Company's convertible loan note of £2.6m, repayable in June 2005, from positive
total assets less current liabilities of £0.7m. Accounting standards require
the nominal value of the convertible instrument, which the directors consider
to be quasi-equity in nature, to be disclosed as a liability on the face of the
balance sheet rather than as a form of equity. As stated in the preliminary
announcement, the directors are considering a range of options to propose to
the holders of the convertible loan in the event that, contrary to their
expectation, some or all of it remains unconverted at the time of maturity. The
convertible loan note has a conversion price of 12p per ordinary share,
compared with market prices of 16p and 35p on 31 December 2003 and 30 March
2004 respectively. Possible alternatives to conversion include further
extension of its maturity date, and redemption at par. A change to the terms of
the loan stock instrument would need to be put to a meeting of its holders. At
this time it is not anticipated that the alternatives under consideration would
require modification of the loan stock conversion price.
