Thank you, Roland. On Slide 19, we have an updated map of our holdings in the Haynesville shale play in North Louisiana and in East Texas. You can see our acreage highlighted in blue. We have increased our acreage to 96,000 gross acres and 82,000 net acres that we believe are prospective for Haynesville shale development. With better natural gas prices and expected well spacing of 80 acres and an expected per-well recovery of 6 Bcfe per well, our acreage could have 4.6 Tcfe of resource potential. On Slide 7 -- on Slide 20, we also outlined our Bossier shale acreage and the base for the same acreage that's prospective for Haynesville is also prospective for the Bossier shale development, which could add another 2.7 Tcfe of potential, as shown on this slide. On Slide 20 (sic) [Slide 21], we recap our activity in our East Texas-North Louisiana region for 2011. Our activity in this region was primarily focused on developing our Haynesville and Bossier shale properties. We drilled 64 wells, 28.3 net, in this region in the 6 different fields, and all but 2 were Haynesville or Bossier shale wells. And all of these wells were successful. We completed 84, or 42.3 net, of our Haynesville and Bossier shale wells in 2011. The wells drilled and completed in 2011 were put on production at an average per-well initial production rate of 10.7 million cubic feet equivalent per day under our restricted choke program. Since we have initiated our Haynesville shale program in 2008, we have now drilled a total of 180 wells and 105.6 net wells. On Slide 22, we provide an update of our backlog both uncompleted Haynesville and Bossier shale wells. We've been talking about this all year since late 2010 when we had the shortage of frac services. As you can see, in the fourth quarter, the number of uncompleted wells decreased from 21 to 14 while the number of net wells increased slightly from 8.9 to 9.8. And the main reason the net increase is because of our 10-well development project where it's ongoing. Most of the remaining wells are scheduled to be completed in the first quarter of this year. Given the current natural gas price, we plan to move all our rigs out of this region by early March and focus for the remainder of this year on our Eagle Ford shale program in South Texas and our Wolfbone program in West Texas. Going to Slide 23, we're going to discuss our South Texas region. All of our South Texas activity in 2011 has been focused on our Eagle Ford program. We drilled 20 Eagle Ford shale wells in 2011 and 19.2 net wells. We have completed 17 of these wells, and that's 17 net, including a well drilled in 2010, which had an average per-well initial production rate of 820 barrels of oil equivalent per day. On Slide 24, we focus on our Eagle Ford shale play in South Texas. We increased our holdings in the Eagle Ford in 2011 to 35,000 gross acres and 28,000 net acres. And using a conservative 100-acre spacing assumption, we believe our acreage, which is all in the oil window of the Eagle Ford, has the potential to recover 83 million barrels of oil equivalent, net to our interest. Slide 25 shows the results of the 19 wells which we have completed and which are currently producing. Since our last update in early December, we have completed an additional 4 wells. The Gloria Wheeler "A" #1H was drilled to a vertical depth of 11,358 feet with a 6,725-foot lateral and was tested at an initial rate of 1,070 barrels of oil per day and 1.1 million cubic feet of natural gas per day or 1,254 BOE per day. The Gloria Wheeler B #1 was drilled to a vertical depth of 10,908 feet with a 5,175-foot lateral, and we tested this well at an initial rate of 916 barrels of oil per day and 1.0 million cubic feet of natural gas per day, or 1,085 BOE per day. The Donnell A #1H was drilled to a vertical depth of 9,404 feet with a 6,481-foot lateral. This well was tested at an initial rate of 646 barrels of oil per day and 200 Mcf per day, or 686 BOE per day. The Cutter Creek #2H was drilled to a vertical depth of 10,013 feet with a 5,541-foot lateral. This well was tested at an initial rate of 471 barrels of oil per day and 400 Mcf of natural gas per day, or 541 BOE per day. And as we've stated before, all of these reported well results were obtained while following our restricted choke program where we manage the choke size and the pressure to improve our EURs. Now I'll turn this over to Jay to discuss our -- oh, okay, he wants me to talk about it, okay. So next is, on Slide 26, we're going to discuss, we closed on the Eagle, on the acquisition of the properties on Reeves County and West Texas from Eagle Oil & Gas and certain of their partners on December 29. We acquired 70,000 gross acres and 44,000 net acres in Reeves County, Texas, in the Delaware basin prospective for the Bone Spring-Wolfcamp development, which we and everybody else are calling the Wolfbone play. The acquisition included 35 producing wells, 22.4 net wells and 4 wells that are -- that were in the process of being completed or 2.5 net wells to be completed. Current net production is around 1,300 BOE per day. The final adjusted purchase price was $345.5 million. We allocated $201.7 million to the 25,200 MBOE of proved reserves we acquired and $143.8 million to exploration acreage, undeveloped acreage. We estimate that these properties have total resource potential of 178 million barrels of oil equivalent based on drilling 935 net vertical wells and we strongly feel there is additional upside in this acreage with horizontal development. Slide 27 is a subsurface topographic view of our Wolfcamp formation, with Comstock acreage shown in yellow. As you can see, the Eagle acreage is located in the bottom of the Delaware Basin on the West side of the Permian basin, which is the optimal location for the basins that are hydrocarbons that we are targeting in the Wolfbone. The primary Wolfbone section runs from about 10,000 feet to 11,500 feet in depth. Also shown here on the east side of the Permian basin the Midland basin, is our Gaines County exploration acreage which is located in the deeper part of the middle basin, again in the lower part of the basin where it's optimal for basins that have hydrocarbons. We own, currently own about 11,000 net acres on, in this exploration play and we'll be targeting the Wolfcamp shale at a depth of 10,000 to 11,000 feet. Slide 28 shows a geologic cross-section from the Delaware Basin in the west to the Midland Basin in the East. The Wolfbone and the Delaware Basin to the west is an emerging resource play and that's where our acreage is located. As you can see, it is equivalent to the Wolfberry play in the Midland Basin, which is the Spraberry and Wolfcamp shales, and this play is very active with significant vertical and horizontal development. On Slide 29, we show Comstock's Permian basin acreage position with 90,000 gross acres and 55,000 net acres under lease. As I've previously stated, the Reeves County acreage provides over 900 vertical, net vertical locations targeting the Wolfbone with 178 million barrels equivalent of research potential. There is also horizontal development potential in the Bone Spring and Wolfcamp formations on that Reeves County acreage. Now our Gaines County acreage to the northeast is primarily targeting the Wolfcamp shale and we expect this to be a horizontal play but we plan to drill a vertical well first to test the section and acquire as much information as possible. Slide 30 shows the calculated ultimate recoveries of recently drilled wells in the Wolfbone play in and around our acreage. As you can see, our acreage has been largely de-risked, and the results shown bracket our expected average EUR of just over 200,000 BOE per well. And this was one of the key reasons we liked and targeted this acquisition because it was largely de-risked. Slide 31 illustrates our 2012 drilling plans for Reeves County. The current wells are shown in yellow and the 2012 scheduled wells are shown in red. We plan to drill 43 gross wells and 33 net wells in 2012 on our Reeves County acreage. Drilling and completion costs should range between $4 million and $4.5 million and our expected EURs are in the range of 180,000 to 250,000 BOE per well, with 30-day IPs expected to be 150 to 300 BOE per day. As I said before, we are primarily targeting vertical Wolfbone completions at this time at a depth of 10,000 to 11,500 feet. Okay, Slide 32. What I want to leave you with is where we think the Wolfbone play is going. On this slide, the various potential oil targets in Reeves County are shown on the left. Primarily, for us it's the Bone Spring and the Wolfcamp section. Also shown are the potential completion types that we anticipate will be prospective on our acreage. On the left side is a conventional vertical Wolfbone well showing the primary 1,500 feet of completion interval in green, with the little green boxes where the completions would be and an additional 1,000 to 1,500 feet of completion potential in the upper Bone Spring, shown with the little red boxes. In addition to that, we believe there are several horizontal targets in the Bone Spring and Wolfcamp that may significantly improve the economics of this play. We have one horizontal Wolfcamp well scheduled this year and other operators in the area are actively pursuing horizontal opportunities in both the Bone Spring and the Wolfcamp. The horizontal aspect of this play is just emerging so there is much science to be applied before it can be verified, but we are very excited to have such a prime position in this basin. Now I'll turn it over to, back to Roland to go over our 2012 drilling program.
