NEWS RELEASE

Issued on behalf of Reed Elsevier PLC and Reed Elsevier NV

12 April 2005

LexisNexis concludes review into unauthorised access to US databases

Further to its announcement of 9 March 2005, Reed Elsevier announced today that LexisNexis, its global legal and business information division, has concluded its review of all data search activity across its business, including its Seisint unit.

The comprehensive review analysed data search activity going back over the last two full years and concluded that there were 59 incidents where unauthorised persons, predominantly using IDs and passwords of legitimate customers of Seisint, may have fraudulently acquired personal identifying information from its US risk management databases. LexisNexis estimates that information on approximately 310,000 US individuals in total may have been accessed. LexisNexis is notifying all these individuals and is offering free support services, including credit bureau reports, credit monitoring for one year and fraud insurance, to monitor and protect them from possible fraud associated with identity theft. LexisNexis will provide fraud counselling services or specialised assistance to any individual who has been the victim of identity theft related to these incidents. LexisNexis has alerted law enforcement authorities and is proactively assisting in their investigations of the potentially fraudulent misuse of the information acquired.

In March, LexisNexis notified approximately 30,000 individuals in relation to the incidents reported in the announcement of 9 March 2005, that criminals could have accessed their personal information. To date, approximately two percent of those individuals have contacted LexisNexis to accept its offer of free credit reports and credit monitoring, and none has so far advised LexisNexis that they have experienced any form of identity theft. The 30,000 individuals are included within the 310,000 total referred to above.

The incidents predominantly relate to misappropriation by third parties of IDs and passwords from legitimate customers of Seisint. The information concerned relates to names and addresses and other personal identifying information such as social security and driver’s licence numbers. LexisNexis and Seisint databases do not hold personal credit histories, medical records or financial records on individuals. Neither the LexisNexis nor the Seisint technology infrastructure has been breached by hackers nor was any customer data compromised or accessed in these incidents. As indicated on 9 March 2005, LexisNexis and Seisint are implementing significant improvements to customers’ password and ID administration security processes to help prevent future incidents. LexisNexis will continue its long established support of effective federal and state data privacy policies and practices.

As announced on 9 March 2005, the financial implications of the unauthorised access to LexisNexis databases are expected to be manageable within the context of LexisNexis’ overall growth. Reed Elsevier also today reaffirmed its 2005 and longer term financial targets of at least 5% organic revenue growth and double digit adjusted earnings per share growth at constant rates of exchange.
