Geographic Focus

Sweetwater Gas Gathering & Processing System

New cryogenic processing plant w/ 120Mmcf/d capacity

Became active late September 2006 Associated gathering system also in

place Expanding gathering system and

capacity to 180 MMcf/d Proximity to Elk City provides flexibility

Sweetwater Plant

Tx Ok

Velma Gas Gathering& Processing System

Located in Golden Trend area of OK 1,080 mi. of active gathering pipeline Approx. 640 receipt points serviced 100 MMcf/d capacity processing facility More then 150 producers under

acreage dedication and long term agreements

Velma Plant

NOARK Pipeline System

Ozark Gas Transmission − 565-mile FERC-regulated pipeline running from Oklahoma to Missouri, 2 compressor stations

Ozark Gas Gathering − 370-mile non-FERC-regulated natural gas gathering system, 11 compressor stations

Increasing capacity from 322 to 450 MMcf/d by adding compression

Accesses prolific Arkoma Basin and developing Fayetteville Shale

Growth Initiatives

Successfully completed four acquisitions totaling over $585 million in the last three years Velma system acquired for $142 million in July 2004 Elk City system acquired for $196 million in April 2005 NOARK system acquired in two separate transactions for a total of $249 million; 75% interest

acquired in October 2005; remaining 25% interest acquired in May 2006

Acquisition Growth

Organic Growth 120MMcf/d Sweetwater gas processing plant opened September 2006; total cost of

$40MM Currently operating at volumes over 90MMcf/d

Expanding gathering system and adding 60 MMcf/d of processing capacity at Sweetwater; expected completion by early 2008

Throughput expansion on NOARK by increasing compression; targeted completion by early 2008 Capacity to increase up to 450MMcf/d; total cost ~ $20-30 million

Continued Appalachian system growth driven by Atlas Energy Resources’ traditional drilling activity and additional potential growth from exploitation of deeper shale plays and other geological formations within their existing acreage position

NOARK Pipeline System Overview High quality FERC-regulated transmission system

Adds stable, fee-based cash flows and reduces risk profile Provides substantial upside without significant capital expenditure requirements

NOARK pipeline diversifies existing APL business and expands footprint Expands Mid-Continent natural gas gathering and transportation position Facilitates additional bolt-on opportunities

Unregulated gathering business Separation of regulated and non-FERC-regulated assets provides growth opportunity APL gathering expertise expected to enhance growth

Strategic location provides access to significant natural gas supply Mid-Continent Region Arkoma Basin Fayetteville Shale – growing production area

Compression expansion project Added compression will increase throughput capacity up to 450MMcfd

Gathering & Processing Overview

1,900 miles of pipelines in Oklahoma and Texas

100 MMcf/d processing plant capacity For the quarter ended ended 9/30/06, processed approximately 58.3 MMcf/d of natural gas and

approximately 6,600 Bbls/d of NGLs

Geographically positioned to benefit from rapidly growing Barnett Shale and

Woodford Shale plays Revenue from purchases of natural gas at the wellhead and sales of

processed gas and NGLs

Gas supply secured under long-term contracts

Throughput growth driven by system expansions and improved compression

Gathering & Processing Overview

Elk City system provides gathering, compression, treating and processing services in the Anadarko Basin Stepped-up drilling activity in the region has increased system gas volumes over 100% since

2002, from 139 MMcf/d to over 284 MMcf/d currently

Supplied by over 300 gas receipt points

System can be enhanced through low-cost system extensions to areas of drilling activity

Location near active drilling area Access to prolific Anadarko basin

Drilling rig count in Oklahoma increased over 95% since 2002

Potential for additional well-connects

Appalachia Recent Developments

Atlas Energy Resources recently announced that during the fourth quarter of

2006 and first quarter of 2007 it plans to drill 3 wells to multiple pay zones,

including the Marcellus Shale of Southwestern Pennsylvania

Atlas Energy Resources believes it holds over 160,000 acres of prospective

Marcellus acreage in three counties

This shale play represents significant throughput potential for Atlas Pipeline

Partners

Industry banter of vertical type-well EUR of “600 to 1,000 MMcfe” within our

range of expectations

Atlas Energy Resources is planning six to ten additional wells in 2nd and 3rd

quarters; potentially a 40+ vertical well development schedule in 4th quarter

2007 and 1st quarter 2008
