In what the companies refer to as a separate deal, CareerBuilder.com has agreed to pay up to $443m to extend until 2013 a contract to be the exclusive search engine for Microsoft's MSN Careers service.
The exact amount paid will depend on performance and traffic, the two companies said.
The MSN/CareerBuilder.com service will also attempt to go international. The companies hope to begin moving the service into Europe at end of 2007.
CareerBuilder.com currently operates sites in Canada, India and the UK, and owns recruiting sites in Sweden and The Netherlands.
The company hopes that the Microsoft brand will help it in Europe.
