Forward Looking Statements

This presentation contains forward-looking statements, which are statements that are not historical in nature. Forward-looking statements are subject to certain risks, uncertainties, and assumptions. Should one or more of these risks or uncertainties materialize or any underlying assumption proves incorrect, actual results may vary materially from those anticipated, estimated, or projected. Among the key factors that could cause actual results to differ materially from those referred to in the forward-looking statements are: weather conditions that vary significantly from historically normal conditions; the general level of petroleum product demand and the availability of supply; the demand for high deliverability natural gas storage capacity in the Northeast and Texas; our ability to successfully implement our business plan; the outcome of rate decisions levied by the Federal Energy Regulatory Commission; our ability to generate available cash for distribution to unitholders; and the costs and effects of legal, regulatory, and administrative proceedings against us or which may be brought against us. These and other risks and assumptions are described in NRGY’s and NRGM’s annual reports on Form 10-K and other reports that are available from the United States Securities and Exchange Commission. Readers are cautioned not to place undue reliance on forward-looking statements, which reflect management’s view only as of the date made. We undertake no obligation to update any forward-looking statement, except as otherwise required by law.

Bakken Crude Oil Production – 2 Million?

7

Bentek projects Bakken production to surpass 1.7 MMBD in 2017 and 2.1 MMBD in 2025 in their base case forecast (2.1 and 2.7 respectively in the high case)

The Bakken shale is situated within the Williston Basin, which is located between the states of North Dakota and Montana and the Canadian province of Saskatchewan

North Dakota has surpassed California and Alaska as the second largest crude oil producing state behind Texas

PADD II will become the second largest crude oil producer behind PADD III by 2013

Nearly 75% of the increase in crude oil production in PADD II will be from the Bakken shale

Bakken crude oil is a light sweet crude of ~40° API and 0.1 wt. % Sulfur

Estimated 68% of total North Dakota production is within a 50-mile radius of the COLT Terminal (located in Williams County)

COLT Hub Asset Overview

Located in Epping, ND Commenced commercial operation in May 2012 120,000 BPD rail loading capacity

− Double rail loop − Connected to the Burlington Northern Santa Fe rail system

Truck unloading facility with capacity of 64,000 BPD

600,000 Bbl of dedicated customer storage capacity

21-mile, 10” bi-directional pipeline (COLT Connector) connects COLT Terminal to Dry Fork Terminal

Interconnected with Hiland gathering system Interconnect with Bear Tracker gathering system

Dry Fork Terminal Overview

Located at the intersection of four major pipelines at the Beaver Lodge/Ramberg pipeline hub

Point of Liquidity

Largest Bakken

Merchant Crude Hub

Integrated network of railcar, pipeline and storage creates optimal source of liquidity and export optionality to optimal crude markets for customers – Railcar transportation provides only means of accessing PADD I and PADD V markets – COLT connector pipeline promotes access to central corridor and intra-region flexibility

Largest storage capacity in the Bakken with room for significant additional tankage Pipeline interconnections with major export lines and intra-regional lines provide sourcing and takeaway flexibility Creates a point of liquidity for Bakken crude oil production by bringing together multiple buyers and sellers

Hub and Spoke

Inergy has built a true “Hub” with multiple ingress and egress “Spokes,” centered around a large battery of tanks – Pipeline provides interconnection with two primary systems (Enbridge and Tesoro) – Interconnection agreements completed – Banner, Tesoro , Enbridge and Bear Tracker – Future connections with other pipelines

Working storage capacity of 720,000 Bbl currently enables the movement of up to 120,000 Bbl/d via rail, 75,000 Bbl/d via COLT Connector pipeline and 64,000 Bbl/d via tanker trucks

Size and scale of COLT will attract crude in a state where 75% of crude gathering still occurs via tanker truck

Via COLT, the COLT connector and its connections, customers have access to Guernsey, Clearbrook, Cushing, the Gulf Coast and PADD I & V refineries

Inergy’s integrated network will be a permanent fixture as the premiere Bakken hub, providing a point of liquidity by bringing together multiple buyers and sellers.

• Current Inbound to COLT – 60% Pipeline, 40% Truck – Truck Unloading – 8 truck racks – COLT Connector – 10” bi-directional with flows mostly into COLT

from Dry Fork (Ramberg/Beaver Lodge) – Hiland – Currently only receipts into COLT – Meadowlark (Bear Tracker) not yet in-service – Pipeline percentages are expected to continue to grow

• Current Outbound from COLT – 99.x% Rail – Rail loading – Enbridge (Beaver Lodge) – Tesoro High Plains (Ramberg) – bi-directional flow – Hiland deliveries awaiting market demand – Truck Loading

14

Terminal - rail, pipeline, truck ins/outs

• Bakken rail goes primarily to the coasts with often quoted transportations costs of:

– East Coast - $14/bbl – Gulf Coast - $13/bbl – Pacific NW - $9/bbl

• Long term transportation incentive to go to the west coast

15

Rail – Where is the volume going

• Rail take away volumes exceeded pipeline take away back in June 2012 and has continued to grow at the expense of pipeline utilization

• Rail impact on pipeline projects is a mixed bag - planned pipeline project have been canceled/postponed (ONEOK) while others do move forward (Pony Express) and other are in limbo (Keystone XL)
