EXTENSION UNTIL MAY 9, 2008 OF THE OFFER PERIOD FOR THE CASH TENDER OFFER BY    
CIDRON SERVICES OY FOR THE SHARES AND STOCK OPTIONS IN TIETOENATOR CORPORATION  
DUE TO THE ONGOING EU COMPETITION CLEARANCE PROCESS                             

Pursuant to the terms and conditions of Cidron Services Oy's tender offer for   
the shares and stock options in Tietoenator Corporation, the offer period will  
expire on April 28, 2008.                                                       

As a result of the ongoing EU competition clearance process, Cidron Services Oy 
hereby extends the offer period to expire on May 9, 2008. Cidron Services Oy    
believes that the EU competition clearance process is progressing well although 
it is taking somewhat more time than initially expected given the level of      
scrutiny by the EU competition authorities of the transaction. Based upon       
currently available information, Cidron Services Oy expects to receive an       
unconditional clearance by the European Commission during the extended offer    
period. Cidron Services Oy does not expect to need any other regulatory,        
governmental or other similar permits, consents, approvals or actions in order  
to complete the tender offer.                                                   

As of April 23, 2008, Cidron Services Oy's tender offer document will be        
available together with this press release and other documents supplementing the
tender offer document.
