5. Services Provided • Dark Fiber • Traditional dark fiber IRUs and leases. • Managed Wavelength Services (DWDM and CWDM) • Maximizes the capacity of valuable fiber infrastructure. • Capability of expanding fiber pair capacity to 64 channels (@10 Gbps). • Enables KC to sell high-bandwidth links while maintaining capacity for additional future sales. • SONET • Traditional TDM services (T-1, DS3, OC-n). • Many customers still rely on SONET services for legacy networks. • Ethernet • Leverage existing SONET and DWDM infrastructure to transport Ethernet from 10 Mbps to 10 GigE. • Many customers are migrating towards Ethernet-based transport due to flexibility and efficiency. • Construction Services • Engineering and Construction of telecom related facilities.

6. Long Island Power Authority and Corporate Services • KC provides various services to KeySpan Corporate Services, LLC (“Servco”), who in turn provides services to other KeySpan affiliates including: • ~1,500 fiber-miles of dark fiber provided to LIPA for the control and protection of the electric transmission and distribution system • ~900 fiber-miles of dark fiber services between various KeySpan facilities (including connectivity for KeySpan data centers) • Bandwidth services used to provide voice and data connections between various KeySpan facilities • KC is also the primary contractor for LIPA-owned fiber • Engineering, design and construction services • Ongoing maintenance and emergency response

7. Revenue Growth Trends

8. How Bandwidth Services Benefit the Business • Enhances the product offerings and options for our customers. • Increased margins for bandwidth sales • Utilizes the same network infrastructure to deliver services to multiple customers. • Bandwidth demand is continually increasing for voice, data & video applications. • Enhances our ability to sell dark fiber. • Enables the company to sustain continuous growth.

9. Summary • KC has become a dominant transport provider for commercial capacity users in the NY area. • KC has continued to achieve steady growth and stability with particular focus on the bandwidth products: • Substantial growth in EBIT 2006 over 2005. • More than 70% growth in Bandwidth revenue 2006 over 2005 • Expanded into new markets (Media, Healthcare, Financial) • Continued network expansion (UK, CT, NJ) • Profitable, Reliable, Expandable.

10. “REAL TIME” Fiber Network Management • Accurate physical representation of network • Splices, slack coils, poles, manholes, street base, etc. • Customer premises build-outs • Node inside plant cage layout, racks, equipment • One location for vital network data • Fiber cable & splicing data • ISP equipment, patch panel & cabinet connection data • Optical systems tracking • Optical circuit troubleshooting features • Locate outage features • Optical system tracing • Network Planning & Project estimating

20. OS Reports

21. Engineering, Planning & Estimating • Provide points of access to network • Splice or slack coil locations • Check capacity on cabling in area • Provide circuit provisioning info from point of access to node • Fiber strand assignments • Cross-connect and endpoint port assignments • Taking into account cabling capacity, route distances and field work, provide scope of “on network” splicing to be performed • Provide circuit distances and predict loss budget for equipment purchase

22. KeySpan Fiber Management System Performance • Network Map maintained at over 99% “REAL TIME” • Optical Systems maintained at 99% “REAL TIME” • Is relied upon for 100% of business activities

23. FMS Keys to Success • Access limited to specific skilled users • Select server subscription with three seat licenses • Bentley Comms users are experienced in Fiber project design, engineering & construction practices • By limiting the user group, control of overall network design is maintained and any “backlog” or “in progress” work considered • Management, Engineering and Operations commitment to system • These groups reliance on the system provides the motivation to ensure timely and accurate information transfer • Financial commitment versus system rewards are understood and supported at all management levels • Checks & Balances • Procedures in place to “sign-off” on completed circuits • Field test results are cross-referenced with Bentley Comms • Field engineers correct & return any discovered discrepancies • Software reliability • Bentley server has operated without interruption since 2000 • No significant data loss since the system purchase thanks to proper back-up procedures and adept user group • System upgrades and excellent related support

24. External uses for FMS data • Recently downloaded fiber network map to Long Island Power Authority ESRI system with help from Microstation GeoGraphics • Aides electric utility in planning future transmission line fiber protection • Benefits KC & LIPA for storm restoration, pole hits, public work projects • FMS data used for various accounting purposes • Tracking Pole licensing • Fiber distance & allocation calculations for back charges to Corporation and other revenue share contracts

25. FMS Marketability – Benefits to our Customers • Customers can trust our commitment to As-Built documentation • Customers can trust our ability to quickly pinpoint system outages • Customers on our network can take comfort in knowing their service will not likely be interrupted due to documentation error

26. KeySpan FMS – A Look Ahead • National Grid – KeySpan merger estimated to be completed by late summer/early fall 2007 • National Grid Wireless US operates 1,100 Route miles of fiber cable in Northeast (MA, RI, Upstate NY) • Remote network monitoring (JDSU) • Deployment of Remote Optical Terminal Units tied into Bentley Comms system OTU-8000 Optical Test Unit for the ONMS Rack-based optical test unit for RFTS (Remote Fiber Test System)
