4. Sri Lanka Scenario • Population– 20 million • Tele density ~ 50%. • Competition remains intense but rational. Strict profitability focus in Operators. • All Operators considering NGN deployment and have issued RFP/Tenders NGN market in Asia provides a potential for a cumulative operator capex opportunity of approx. $3.9B* over 2007-2010 and $0.9B* in 2008 * Based on forecast provided by Infonetics Research in Nov 2007

5. Convergencehappening everywhere & traditionally isolated markets are overlapping Information Voice Broadcast Entertainment Data Telecom Communication Multi-Media Internet Computer Electronic Home App. Terminal Media Convergence Industry/Service Network Terminal • IP based • Heterogeneous environment • Ubiquitous Network Convergence in Telecommunications • Continuity of services & content • Broadband based • Supporting mobility Service Terminal • Convergence faculty • Smart facility • User friendly interface

6. What is NGN • NGN is a concept for defining & deploying networks, which due to their formal separation into different layers & planes and use of open interfaces, offers service providers a platform which can evolve in a step-by-step manner to create, deploy & manage innovative services. • NG Architecture : Service oriented, layered (transport, control, application) • NG Services : Converged (quad play- voice, data, video & mobility) • NG Access : High speed (Broadband) IP based connectivity (ADSL,VDSL, WiMax, Cable TV, FTTH) • NG Transport : Ethernet, IP-MPLS, RPR, T-MPLS • NG Mobile : 3G+, 4G • NG Internet : IPv6 • NG Interconnect : Capacity and Quality based • NG Licensing : Unified, Converged

7. NGN Market Drivers • TDM switches facing EOL or reaching capacity saturation • Explosive growth in Internet traffic • Intense competition • Telco vs. Cable vs. Satellite vs. Wireless vs. NGN • Need for Improved Business Model • OPEX savings and top-line revenue growth • Need for Service Differentiation • Ease in offering new services (VoIP, IPTV, FMC) • Time-to-market and ability to provision services quicker • Integration of network resulting in huge network cost savings

13. FMC-Business Drivers CALL FAILED PLEASE TRY AGAIN! • Many households today have at least one cell phone. • In these households estimated 60% of long distance calls and 36% of local calls take place on mobile phone at home (Yankee Group) • 14% of users use cell phones as their primary line (Yankee Group) • Additional 26% of users are ready to switch as in-building coverage improves • Over 50% of users place mobile calls when they are at home or office (Wireless Review) • WiFi exists or can be supported in both places • Traffic on mobile network has been increasing causing QoS problem and hence subscribers’ churn • Pressure to reduce tariff for voice services • “Fixed” broadband availability is growing at a rapid pace - double digits in most cases • VoBB provides new revenue stream for Service Provider, and also give a low cost alternative to carry mobile voice traffic • Leverage low fixed line asset cost to support the mobile voice application • Users need to access services seamlessly regardless of their location, active device or the network access method • Lower CAPEX, Lower OPEX, Higher coverage and quality

14. Driving Forces • Consumers like mobile phones • And all of them are not using just for mobility • In >50% cases used for portability, not mobility. • Consumes demands low cost for voice • Broadband is getting widely deployed • Voice over broadband is not only new revenue stream for SP, but also the low cost alternative to carry mobile voice traffic • Leverage low fixed line asset cost to provide the mobile voice application • Lower CAPEX, Lower OPEX, Higher coverage and quality => Fix Mobility Convergence
