## East Texas/North Louisiana Region 

Approximately 59% or 343.8 Bcfe of our proved reserves are located in East Texas and North Louisiana where we own interests in 956 producing wells (584.8 net to us) in 28 field areas. We operate 662 of these wells. The largest of our fields in this region are the Logansport, Toledo Bend, Beckville, Waskom, Blocker, Mansfield, Douglass and Darco fields. Production from this region averaged 128 MMcf of natural gas per day and 175 barrels of oil per day during 2013 or 130 MMcfe per day. Most of the reserves in this area produce from the upper Jurassic aged Haynesville or Bossier shale or Cotton Valley formations and the Cretaceous aged Travis Peak/Hosston formation. In 2013, we spent $16.7 million drilling two wells (2.0 net to us) and $2.3 million on workovers and recompletions in this region. The two wells we drilled in 2013 were Bossier shale horizontal wells. We have not budgeted to drill any wells in this region in 2014. 

## Logansport 

The Logansport field located in DeSoto Parish, Louisiana primarily produces from the Haynesville and Bossier shale formations at a depth of 11,100 to 11,500 feet and from multiple sands in the Cotton Valley and Hosston formations at an average depth of 8,000 feet. Our proved reserves of 232.8 Bcfe in the Logansport field represent approximately 40% of our proved reserves. We own interests in 252 wells (161.9 net to us) and operate 178 of these wells in this field. 

## Toledo Bend 

The Toledo Bend field in DeSoto and Sabine Parishes, Louisiana was discovered in 2008 with our first horizontal Haynesville shale well. Production from the Haynesville shale in the Toledo Bend field ranges from 11,400 to 11,800 feet and from 10,880 to 11,300 feet in the Bossier shale. Our proved reserves of 31.1 Bcfe in the Toledo Bend field represent approximately 5% of our reserves. We own interests in 76 producing wells (39.3 net to us) and operate 41 of these wells in this field. During 2013 we drilled two horizontal wells (2.0 net to us) at Toledo Bend and we completed two wells (0.1 net to us) that were drilled in 2012. 

## Beckville 

The Beckville field, located in Panola and Rusk Counties, Texas, has estimated proved reserves of 30.6 Bcfe which represents approximately 5% of our proved reserves. We operate 191 wells in this field and own interests in 78 additional wells for a total of 269 wells (159.3 net to us). The Beckville field produces primarily from the Cotton Valley formation at depths ranging from 9,000 to 10,000 feet. The field is also prospective for future Haynesville shale development. 

## Waskom 

The Waskom field, located in Harrison and Panola Counties in Texas, represents approximately 2% (12.7 Bcfe) of our proved reserves as of December 31, 2013. We own interests in 63 wells in this field (39.8 net to us) and operate 47 wells in this field. The Waskom field produces from the Cotton Valley formation at depths ranging from 9,000 to 10,000 feet and from the Haynesville shale formation at depths of 10,800 to 10,900 feet. 

## Blocker 

Our proved reserves of 12.1 Bcfe in the Blocker field located in Harrison County, Texas represent approximately 2% of our proved reserves. We own interests in 77 wells (71.0 net to us) and operate 71 of
