plants that service our natural gas gathering systems include ten cryogenic facilities with approximately 873
MMcf/d of processing capacity and one refrigeration facility with approximately 45 MMcf/d of processing
capacity. Further, our Minden and Discovery processing facilities both have ethane rejection capabilities that
serve to optimize the value of the gas stream. The natural gas storage facilities include 850 MMcf of leased
storage on our Pelico system, and our 33.33% interest in the Southeast Texas system’s 9 Bcf salt dome storage
facility. In addition to our existing assets, we are constructing a 200 MMcf/d cryogenic natural gas processing
plant in the Eagle Ford shale, or the Eagle plant, that we expect to be completed by the fourth quarter of 2012
and an additional storage cavern at Southeast Texas that we expect to be completed by the third quarter of 2013.
During 2011, the volume throughput on our assets was in excess of 1.2 Bcf/d, originating from a
diversified mix of natural gas producing companies. Our systems each have significant customer acreage
dedications that will continue to provide opportunities for growth as those customers execute their drilling plans
over time. Our gathering systems also attract new natural gas volumes through numerous smaller acreage
dedications and also by contracting with undedicated producers who are operating in or around our gathering
footprint. During 2011, the combined NGL production from our processing facilities was in excess of 39,000
Bbls/d and was delivered and sold into various NGL takeaway pipelines or transported by truck.
Our natural gas gathering systems have the ability to deliver gas into numerous downstream transportation
pipelines and markets. Many of our outlets transport gas to premium markets in the eastern United States, further
enhancing the competitiveness of our commercial efforts in and around our natural gas gathering systems.

(f) Our East Texas complex comprises 5 cryogenic processing plants.
Our Northern Louisiana system includes our Minden and Ada systems, which gather natural gas from
producers and deliver it for processing to the processing plants. It also includes our Pelico system, which stores
natural gas and transports it to markets. Through our Northern Louisiana system, we offer producers and
customers wellhead-to-market services. Our Northern Louisiana system has numerous market outlets for the
