Monster maintained its position as the most popular site in the category

closest competitor. Stepstone ranked 2nd with 2.9 million visitors, followed
closely by ANPE Sites with 2.8 million visitors and Bundesagentur fur Arbeit
with 2.5 million visitors.

"With nearly 54 million visitors in a typical month during the fourth
quarter of 2007, the career services and development category continues to
attract a significant share of the total European Internet audience," said
Bob Ivins, EVP of European Markets for comScore. "Traffic to these sites
represents a bellwether for the job market, and if economic conditions worsen
over the coming months and cause an increase in the unemployment rate, we can
expect to see visitation activity at these sites climb."
