Competition and Risks

7

� Competitive transportation options are good for customers

� Policy changes bring financial and timing risks

� Predictability is KEY to project development

Commercialize

Market participants need early line of sight to take-away in order to make their core business decisions.

Project Development

Pipelines must deploy significant capital in advance of regulatory authorizations to meet customer needs.

Regulatory Authorizations

Required approval process must be efficient and predictable.

Markets and Rates

8

� Market demand and supply areas have significantly changed and

pipelines must respond competitively

� Aging infrastructure brings new challenges for captive markets needing

enhanced reliability of service

� Rates on modern pipelines compete with legacy max rate pipelines

� Cost recovery mechanisms are challenged

Performance

9

� Current policy and guidelines are effective (when pipelines follow them)

� Early public, landowner and agency outreach

� Thorough planning and applications are a necessity

� Proactive engagement when alternative approaches are needed

� Follow-through and communication are imperative

� Good actors are quickly forgotten when bad actors are in the spotlight

� Proper agency response to bad actors would mitigate all pipelines being

painted with the same brush

Customer Service

10

� Develop partnerships with customers to bring value to both them and the

pipeline

� Provide full life cycle service

� Creativity and innovation necessary for success

� Respect pipeline tariffs but do not hide behind them

REX Response to Change

Original

2009 – 2013

2014 – 2019

Future

2019 and Beyond

� West-to-East – REX originated shipping solely West-to-East

� West-to-East – West-to-East transport continues to play an important function for REX

� Seneca Lateral and East-to-West Projects – Contracted base 1.8 bcf/d of East-to-West capacity in Zone 3

� Capacity Enhancement – Increased East-to-West capacity from 1.8 bcf/d to 2.6 bcf/d in Zone 3

� Direct Market Access (to be constructed) – REX is constructing interconnects for Vectren, NTE, and IPL in 2017

In Summary…..

� Predictability is KEY

� Timing of regulatory authorizations must be reasonably predictable

� Policy changes must be well thought out and implemented

� Pipeline differences need to be realized

� Good actors versus bad actors

� Legacy versus new

� Competitive versus captive
