3 TGP System Overview

4 Tennessee Gas Pipeline System Overview Proudly providing reliable service for over 70 years 11,900 miles of pipeline 96 Bcf of storage capacity ~9.6 Bcf/d design capacity Abundant & Growing Supply Utica Shale Northeast Marcellus Shale Haynesville Shale Southeast EagleFord Shale 4

5 Changing TGP Operations Line Line 300 Line 300 Line 300 Line 100 Line 800 Line 500 Line 500 Line 100 Line 800 Line 500 Line Designed to deliver TX/LA supply to Northeast markets High utilization of 100/800/500 lines, high seasonal utilization of 200 and 300 lines Consistent imports on the Niagara Spur Shale Supply: Marcellus via 300 Line ~3.2 Bcf/d, Marcellus via Broad Run ~400k, and Utica via 200 Line ~1.3 Bcf/d Serving Markets across system; LDC s, Power Plants, Pipeline Interconnects. System Flows have reversed on much of the System: 317 -> 219 ->100/500/800 lines High System Utilization Year Round Consistent exports on Niagara Spur 5
