Why Offer Hybrid Networks? • • • Terrestrial offers several advantages over VSAT for Why Offer Hybrid Networks? • • • Terrestrial offers several advantages over VSAT for data networks… – – – Compelling pricing (especially in consumer networks) Low latency (better for some applications) Greater familiarity within the IT community …although VSAT still retains several important advantages – – – Ubiquitous availability Multicast support Control of the last mile Increasing DSL footprint, technology maturity are increasing customer demand Spacenet sees itself as a services provider, not just a VSAT operator Hybrid networks are a competitive differentiator Allows us to build on the customer relationship FCC Satellite Forum - March 21, 2005 COPYRIGHT 2005 SPACENET INC. 6

Integrated Services Challenges • • “Thinking terrestrial” Choosing service mix (DSL, private lines, Frame Integrated Services Challenges • • “Thinking terrestrial” Choosing service mix (DSL, private lines, Frame Relay, others) Choosing a business model (how much infrastructure investment? ) – – Facilities-based providers vs. reseller/ISPs Layer-2 vs. Layer-3 services Developing terrestrial know-how (VSAT is the hard part!) Creating a business case for where terrestrial fits into your offerings – – – Majority-terrestrial networks Terrestrial gap-fill for VSAT (line of sight, building rights issues) Terrestrial and VSAT together for different applications or failover connectivity Dealing with the complexities of terrestrial installations Determining customer needs Creating marketplace-competitive offerings FCC Satellite Forum - March 21, 2005 COPYRIGHT 2005 SPACENET INC. 8

Spacenet’s Integrated DSL Offering • • • Services for franchise/SME through enterprise needs – Spacenet’s Integrated DSL Offering • • • Services for franchise/SME through enterprise needs – – – ADSL services on the low end SDSL/IDSL services on the high end Dual-pipe solutions for special needs DSL services are routed back to the Spacenet hub for a seamless hybrid network – – Terrestrial and VSAT sites can share IP space, be managed as part of one WAN Allows for centralized firewalling/network management just as with VSAT Unifying the services: – – Same NOC/NMC handles trouble tickets for DSL and VSAT customers Customers receive one bill Orders are placed through the same fulfillment system Live prequalifications for both terrestrial and VSAT There are still differences: – – Terrestrial on-site maintenance doesn’t have the flexibility of VSAT offerings Different contract terms, different AUP/usage restrictions Enthusiastic response from customers FCC Satellite Forum - March 21, 2005 COPYRIGHT 2005 SPACENET INC. 10

Integrated Services – Moving Forward • In markets where terrestrial is a factor, it Integrated Services – Moving Forward • In markets where terrestrial is a factor, it must be addressed – – • • • Some markets will always remain VSAT-centric When there is open competition on connectivity services, terrestrial has an important place Spacenet has not seen meaningful cannibalization of its VSAT market – – Most deployments are gap-fills on VSAT networks Opportunities for VSAT and terrestrial in primary/secondary configuration Some customers actually switch to VSAT once they experience the problems of large terrestrial rollout Success is dependent on developing the attitude of a “service provider” – – – Are you a hardware-specific operator or a solutions provider? Successfully implementing one terrestrial platform opens the door to many other future service offerings Things like Wi. Max/EVDV and others represent future threats to VSAT data networks that will need to be addressed in time as well FCC Satellite Forum - March 21, 2005 COPYRIGHT 2005 SPACENET INC. 11
