2. Wholesale Carrier’s Carrier providing broadband transmission capacity and Transit IP services to Teleco’s, ISP’s CableTV Ops. for voice, data and video applications A wholly owned subsidiary of Columbus Communications Inc, a privately held Barbados-based company. Majority owner of the Americas Region Caribbean Optical-ring System ARCOS-1 Cable Network Existing connectivity and services to 18 countries…and growing ARCOS The only undersea fiber-optic cable network ring connecting the U.S., Mexico, Central America, South America and the Caribbean Well established Commercial Partnerships in the Region About New World Network

3. Market drivers - increasing demand for IP After the Dot.Com collapse in 2001, the Telecom Industry is gradually recovering and today represents an average 3% of the Global GDP Connectivity and value added services (mostly IP based), represent the largest market segment growth followed by mobile services, and finally fixed line POTS. The CALA region represents 10% of the world market Worldwide there are more than 300 million Internet users, CALA represents only 16 million, low penetration provides opportunity DSL network deployment is substantial with double the number of lines each year Mobile telephony continues with strong growth but Mobile data services are under-developed in the region

4. Growth in regional TV Cable network operators investing in broadband infrastructure, provides service triple play of video, voice and internet Future Wireless Broadband network deployment provides yet another potential demand for IP Transit. The corporate market is the fastest growing segment for Internet and Data applications, replacing traditional Leased Line Service. In our region Voice Over IP (VoIP) already represents 15-20% of the total international minutes market For historical reasons Internet and the World Wide Web are USA Centric with regional demand for IP connectivity, north bound to the USA. In our region e-commerce transactions have grown from $500M in the year 2000 to $3,500M in 2004 Market drivers - increasing demand for IP

5. New World Network - Goal The Company is committed to the expansion of its high quality Transit IP network and service in continuing to meet the significant growth in customer demand. Our ‘Goal’ it to be a premiere provider of wholesale IP capacity to the region

11. IP Network Points of Presence Dual Juniper M320 Core Routers –Fully redundant DC power plants –4 independent power supplies per chassis –Dual route processors per chassis –Dual OC-192 core connections to other POPs –Diverse transmission paths between POPs –10GigE core within each POP –STM-4 to STM-16 customer connections available at each POP –GigE customer connections available at each POP –Optional 1+1 card protection available for SDH-based and GigE connections

12. IP Network Points of Presence Juniper E-Series Edge Routers –Fully redundant DC power plants –2 independent power supplies per chassis –Dual route processors per chassis –Multiple GigE uplinks into core –Load-balancing and failover into core –E1 to STM-1 customer connections available –1+1 card protection available for SDH-based connections

13. IP Network Points of Presence Upstream Connectivity –Multiple Tier 1 connectivity at each POP –Diverse upstream connectivity provides highly redundant services to customers –OC-48 base interface to upstream providers* –Traffic balanced over major tier 1 backbones –Intelligent traffic management through advanced OSS systems** * Migration to OC-192 Upstream connection as required ** Additional functionality installed 3Q2006

15. Undersea Cable IP Service Protection X Miami Colombia EAST WEST SDH - SNCP Switch Network IP service is ring protected using Sub Network Connection Protection (SNCP). In the event of signal failure caused by loss on transmission on the active circuit path, protection switching automatically restores service <50ms. (2) RX Signal Path Switch (1) Signal Splitter Miami 50%0% IP Router Switching Customer IP service protected trough traffic load balancing across two capacity pipes A&B. In the event of failure caused by transmission interruption on one circuit path, traffic is automatically loaded (switched) 100% on to alternate pipe. X 50% 100% AB A B

16. Undersea Cable IP Service Protection Additional Diversity Options Miami POP 50%0% At the IP layer several redundancy options may be considered to enhance service protection. X 50% 100% AB AB BOCA POP Customer POP A Customer POP B End User USA Upstream In this example Customer IP traffic is again protected with load balancing across two capacity pipes A&B. Further router redundancy may also be provided with each pipe terminating in a separate physical location in NWN & Customers network. Solution provides both route and terminal POP diversity

17. Undersea Cable IP Service Delivery Efficient delivery of High Capacity Delivering Tiered Service over High Capacity Interface STM-4, STM16 (SDH) Undersea Cable network efficiency OK, Increments of STM-1, STM-4c, STM-16c (SDH) Undersea Cable network efficiency may be low. Whole bandwidth must be provisioned regardless of customer committed rate. GigE (GFP) Undersea efficiency remains high whilst providing customer flexible high capacity interface. Granular use of network capacity. Increments of STM-1 up to 7 STM-1’s providing 1Gbps bandwidth. 

18. IP Service

19. IP Transit Service Quality of service One of the best Service Level Agreements in the region 100% network availability Less than.03 % packet loss 50ms average or less latency Intelligent Routing Traffic from the NWN is directly routed to all major IP backbones using an overlay network of Tier-1 providers and regional peering Flexible billing solutions NWN IP Transit Service is offered as full port, tiered or burstable connection, to meet the need of your bandwidth demand and business model Scalable connections Bandwidth available from E1 to Gigabit speeds Built-in redundancy Connection to major IP backbones through our state- of-the-art submarine broadband fiber optic ring network, protected at the SDH layer using SNCP path protection. Switching < 50ms. Network Management NWN IP Transit provides one point of contact at NWN’s Bilingual Network Operations Center (“NOC”) providing high network availability and performance Monitored and maintained 24X7

20. Flexible Scalable Service & Billing Full Port : Provides customer maximum IP bandwidth according to port interface i.e. E1 ~1.9Mbps DS3 ~ 43Mbps, STM-1 ~ 150Mbps. Burst Rate : IP bandwidth provided over a given interface e.g. STM-1 with minimum commitment bandwidth 30Mbps. Customer is able burst beyond commitment, for example 60Mbps allowing customer to instantly support ad-hoc demand for additional bandwidth. Tiered Rate: IP bandwidth provided over a given larger bandwidth interface i.e. STM4 – GigE, with fractional amount of capacity activated. NWN and Customer can quickly add additional capacity with minimum additional network change. The perfect solution for fast expanding network demands.

21. IP Service – Additional Features Domain Name Services –Primary and secondary DNS services available as options based on hardened, secure, and redundant DNS delivery platform –Multiple forward and reverse lookup zones, capable of hosting large allocations of IP address space –Quick response and fulfillment of DNS updates, handled by NWN’s Network Operations Center, 24x7x365 Monitoring and Management Services –SNMP Trap Delivery Service  SNMP trap-based alarm delivery from NWN’s network management systems to customer network management systems  Custom delivery and/or filtering of standard SNMP traps for particular customer services

22. IP Services – Additional Features Security Services –Denial of Service (DOS) Attack Mitigation  NWN supports the use of the “black-hole” community transmitted through BGP  Allows customers to selectively “black-hole” DOS-based traffic before reaching their networks –Network Ingress Filtering  NWN is systematically configuring it’s IP core to ensure RFC 2827 compliance  Protects against spoofed-address attacks, that may result in security incidents or Denial of Service attacks

23. Conclusions The Caribbean Market, has experienced a dramatic growth in demand for Internet and Data services and subsequent demand for international broadband connectivity. Internet in the Caribbean Market will continue to require US based IP Transit connectivity as most of the access for content, portals and websites are located in the USA New World Network is making the necessary multi-million dollar investment in expanding its core IP network enabling the company to continue to meeting Customer demand.
