OUR MARKET OPPORTUNITY (SUMMARY)

     With the rapid adoption of the Internet, we believe the advantages of
online training can now be marketed to both large and small businesses, as well
as to home office users, in a cost-efficient manner over the Internet. IDC
estimates that the U.S. corporate market for training and education presented
over the Internet will increase from $550 million in 1998 to approximately $11.4
billion by 2003, an 83% compound annual growth rate.

OUR MARKET OPPORTUNITY (BUSINESS)

     IDC estimates that the U.S. corporate market for training and education
presented over the Internet will increase from $550 million in 1998 to
approximately $11.4 billion by 2003, an 83% compound annual growth rate. The
largest component of IDC's corporate learning market is "content," such as our
courses, which it estimates will increase from $391 million in 1998 to
approximately $6 billion by 2003. The second largest component is learning
services, such as needs assessments, program-building components, technical and
systems integration, site management/hosting, maintenance and online monitoring.
Many of these services are incorporated into our courses. IDC estimates that
this component of the market will increase from $99 million in 1998 to
approximately $4 billion by 2003. The balance of the market consists of delivery
solutions, such as authoring tools, course management systems, collaborative
software, virtual classrooms and add-on tools, that we do not provide.

OUR COURSES AND SERVICES

     COURSES. IDC divides education and training presented over the Internet
into information technology and non-information technology courses. It estimates
that information technology training, which includes information technology
training and desktop applications training, will increase from $440 million, or
80% of the market, in 1998 to approximately $5 billion by 2003. IDC further
estimates that non-information technology training will increase from $110
million, or 20% of the market, in 1998 to approximately $6 billion, more than
50% of the market, by 2003.
