Amendment No. 5 to Network Services Agreement

That certain NETWORK SERVICES AGREEMENT (the “Agreement”), dated September 28, 2001, by and between SAVVIS Communications Corporation, a Delaware corporation (“SAVVIS”), and Reuters Limited, a company incorporated in England under registered number 145516 (“Reuters”), as amended, is hereby further amended effective July 23, 2003 (the “Effective Date”) by this Amendment No. 5 (the “Amendment”), as follows:

13. SERVICE DEFINITION –“NETWORK-BASED SECURITY SERVICES”

13.1 Overview

The stateful inspection firewall is an extension of the basic packet filtering architecture employed by most routers. Stateful inspection occurs at the Media Access Control (MAC) or network layer, thus making it fast and preventing suspect packets from moving up the protocol stack. Unlike static packet filtering, however, stateful inspection makes its decisions based on all the data in the packet (corresponding to all levels of the OSI stack). The state of the connection is monitored at all times (hence stateful inspection), allowing the actions of the firewall to vary based on the administrator-defined rules and the state of previous communications. The firewall is capable of remembering the state of each ongoing communication across it, thus allowing it to effectively screen all packets for unauthorized access while maintaining high security, even with connectionless protocols such as User Datagram Protocol (UDP).
