In response to market demand for cleaner fuels, in late 2008 Exxon Mobil announced it will invest more than $1 billion in three refineries (Baton Rouge, Louisiana; Baytown, Texas; and Antwerp, Belgium) to increase the supply of cleaner burning diesel by about six million gallons per day. In 2009 it made its first major investment in developing biofuels, agreeing to spend $600 million in an algae-to-fuel project with biotech firm Synthetic Genomics.

Our current acreage position is approximately 22,000 gross acres. Additionally, we are continuing to lease mineral rights from local landowners. We also plan to pursue large producing property acquisitions as they become available. Primarily our acquisitions and leases are in Webb and Zapata Counties, two of the leading natural gas producing counties in Texas. Extending throughout these counties is the Lobo Wilcox Trend, one of the largest gas producing regions in the United States. This play has produced more than 6.4 Tcf gas equivalent from more than 4,200 completions. We are a significant taxpayer in Webb and Zapata Counties and we hire dozens of local contractors with hundreds of employees working on Laredo Energy projects. We also generate significant revenue for local landowners with whom we have natural gas leasing agreements. Since its inception in 2001, Laredo Energy has drilled 82 wells in Webb and Zapata Counties, and continues to drill 20 to 30 wells per year. Laredo Energy Management consists of: Glenn Hart, Jerry Holditch, Ken Cravens, Doug Fogle, Robert Swanson, Scott Stevenson, Doug Kaiser, Jim Flowers, Steve Jaques and Paul Thompson.

Chesapeake Energy Corporation 6100 N. Western Ave. Oklahoma City, OK 73118 Phone: 405 848-8000 Fax: 405 843-0573 Chesapeake Energy knows the peaks and valleys of the oil and gas business. The exploration and production company (named after the childhood Chesapeake Bay haunts of a founder) builds natural gas reserves through the acquisition and development of oil and gas assets across the US. In 2010 the Mid-continent region accounted for more than a quarter of the company s estimated proved reserves of 17.1 trillion cu. ft. of natural gas equivalent, but Chesapeake also has assets along the Gulf Coast, in Appalachia, and the Ark- La-Tex region. In 2010 the company had more than 22,600 producing oil and natural gas wells that produced 1,035 billion cu. ft. of natural gas equivalent per day, 89% of which was natural gas. Chesapeake is one of the top drillers of natural gas wells in the US, with drilling projects in Arkansas, Kansas, Louisiana, New Mexico, Oklahoma, and Texas. The company operates about 160 drilling rigs. A national leader in deep vertical and horizontal drilling, Chesapeake is concentrating on growing its proved reserves through acquisitions. It is also seeking to save costs by owning and operating its own equipment. In 2010 Chesapeake began shifting its strategy from capturing new drilling inventory to stepping up its program to convert what had been inactive fields into developed producing reserves. Utilizing horizontal drilling technology combined with hydraulic fracturing and 3-D seismic information, the company plans to increase production in wells that had previously thought to be tapped out. Facing a deepening economic valley as oil prices began to slump, in 2008 the company moved to cut the costs of exploiting its shale assets by selling some of these properties to joint venture partners. In this regard Chesapeake sold 90,000 net acres of natural gas assets in the Arkoma Basin Woodford Shale play for $1.7 billion to BP. It subsequently sold a 25% stake in its Fayetteville Shale assets in Arkansas to BP for $1.9 billion. In 2009 Chesapeake formed a joint venture with Global Infrastructure Partners to operate natural gas midstream assets. And in early 2010 it also sold 25% of Barnett Shale properties to TOTAL, forming a $2.25 billion joint venture with that company. It also agreed to sell a 33% stake in its shale play in south Texas to CNOOC for $1.1 billion. Chesapeake sold its assets in the Permian Basin of West Texas and southeast New Mexico to Riverstone Holdings in 2010. Riverstone manages a group of energy-focused private equity funds. These moves plus a rebounding global economy and higher commodity prices helped the company to post robust revenues and net income in 2011. Looking to raise cash for future investments, in 2011 Chesapeake decided to sell all of its Fayetteville Shale assets to BHP Billiton unit BHP Billiton Petroleum for about $4.8 billion. It also announced plans to sell its stakes in Frac Tech Holdings and Chaparral Energy. As part of its strategy to reduce costs by having more ownership of the rigs it uses to drill its wells, in 2011 the company agreed to buy Bronco Drilling (which owns 22 rigs) for $315 million. Chesapeake will integrate Bronco s assets into its Nomac Drilling subsidiary (95 rigs). 3

(East), was established as a Pennsylvania Corporation in 1983. Today, the company has offices in Warrendale, Pennsylvania, Parkersburg, West Virginia, Allegany, New York, and Denver, Colorado and operates as an independent oil and gas producer in Pennsylvania, West Virginia, New York, and Colorado employing approximately 205 office and field personnel. The company s first operating properties were drilled in 1984 in Warren and Indiana Counties, PA. Several key acquisitions of both acreage and producing properties led East to expand its operations into McKean County, PA, and West Virginia, most notably its acquisition of certain Pennzoil assets in the Appalachian Basin in 2000. With five current waterflood projects as a part of its over two thousand active wells, East is the largest oil producer in the Appalachian Basin, producing 3,500 barrels of oil daily. East is one of the basin s most active exploration and production companies and expects to drill over 300 wells in 2005. The company is an aggressive land and leasing company and currently holds approximately 1,000,000 acres of oil and gas rights in the Appalachian Basin. East, along with industry partners, is one of the most active explorers for deep Appalachian gas reserves in the Ordovician Black River gas play of south central New York. East was responsible for the discovery of three separate fields in the Watkins Glen area and had acquired over 250,000 acres of leasehold rights in the play by 2001. East sold its interests in these producing fields and nearby acreage in late 2002, but remains active in the play, exploring acreage retained after the sale. The company has been credited with the discovery of five new fields since 2002 in the Elmira, New York area and continues to actively develop its acreage position, now estimated at nearly 75,000 acres. East is also an owner of Northern Pipeline Company, LLC. Northern Pipeline Company owns approximately 400 miles of gathering lines which stretch from the Butler-Clarion County, PA line north to the New York state line, traveling through Clarion, Forest, McKean, Venango and Warren Counties. East also owns approximately 100 miles of gathering lines from the Butler / Clarion County line south through the Pittsburgh area to the Pennsylvania-West Virginia border, plus 60 miles of gathering lines in Lancaster, Chester, and Delaware Counties, PA. The pipelines have been critical in marketing East s production and carry ever-increasing volumes of gas as other operator s begin to utilize the system s capacity. East is an owner in two natural gas processing facilities in Northern Pennsylvania, currently capable of processing over 20.0 million cubic feet of gas daily for itself and other producers. East s West Virginia operations include a 5,200-customer public natural gas utility, serving homes and businesses all over the state. East currently utilizes over 1,000 miles of gathering and utility lines to both serve these customers and gather its other gas production. In early 2004, East opened an exploration office in Denver, Colorado. The company successfully participated in three U.S. Bureau of Land Management lease sales in Colorado and Utah in 2004, and along with other key private acreage acquisitions, has leased nearly 175,000 acres of prospective oil and gas properties in the Greater Rocky Mountain Region.
