ADDITIONAL INFORMATION ON THE ACQUISITION OF OPUS360 CORPORATION

ADDITIONAL INFORMATION ON THE ACQUISITION OF OPUS360 CORPORATION On April 11, 2001, Proha Plc announced the acquisition of an US- based Nasdaq-listed software company, Opus 360Corporation. A press conference will be held today, April 17, 2001 at 10:00 am for the media and at 12:00 am for the financial analysts at Scandic Hotel Marski, Neptun cabinet, address: Mannerheimintie 10, Helsinki. ACQUISITION'S FINANCIAL EFFECT ON PROHA The acquisition of Opus360 is in line with Proha's growth strategy. The products of Opus360 complement Proha's product offering in Project and Resource Collaboration. In the short run, the acquisition will not have a substantial impact on Proha's net sales forecast. If the Opus360 acquisition is closed, the result of Opus360 will have an essential impact on the financial result of Proha Group in 2001. Even in that case, the consolidated result of the Proha Group is estimated to remain positive. Proha's management sees that the profitability of the current Proha Group remains unchanged. In spite of the result of Opus360, the acquisition will have a positive impact on Proha's financial position. POSSIBLE RISKS OF THE ACQUISITION The terms and conditions of the acquisition include a Walk Away clause according to which Proha will be able to reject the acquisition in certain circumstances; for example if the cash flow as a result of the Opus360 restucturing program will be substantially smaller than expected. The entire agreement has been delivered to Securities and Exchange Commission for publishing. The agreement is available on the Nasdaq internet site at the address www.nasdaq.com. STEPS TO PRESERVE NASDAQ-LISTING HAVE BEEN TAKEN Based on the agreement as well as other steps Opus360 has taken, Opus360 has made an appeal to a Nasdaq Listing Qualifications Panel to continue the trading of the Company share on the Nasdaq National Market. At this time, Opus360 is in compliance with all of Nasdaq's continued listing requirements except for the share price which is below one dollar. The Opus360 share will continue to be traded on the Nasdaq National Market until the Nasdaq Listing Qualifications Panel makes a formal decision and notifies Opus360 about it. In the event the shares are delisted from the Nasdaq National Market, Opus360 will attempt to have its share traded on the NASD OTC Bulletin Board. APPLYING FOR THE MAIN LIST OF THE HELSINKI STOCK EXCHANGE Due to the Opus360 agreement and the possible Nasdaq-listing of Proha's Artemis subgroup related to the agreement, Proha's application for the main list will be delayed for the present.
