PENN VIRGINIA Economic sensitivities for PVOG by major play CORPORATION • PVOG’s plays generate attractive after-tax returns even at prices below current levels (current 12-month NYMEX strip $8.26 per MMBtu) • Hedges protect the downside economics of certain plays with floors between $7.25 and $8.50 per MMBtu 90 80 70 After-tax Rate of Return % 60 S.

CORPORATION Penn Virginia Oil & Gas PENN VIRGINIA Overview of Shale Plays 8

PENN VIRGINIA CORPORATION Summary of PVOG’s major shale plays • Devonian / Marcellus Shale − Lower Huron and Marcellus effort in WV and Marcellus in PA − Approximately 87,500 net acres with net unrisked reserve potential in excess of 250 Bcfe − Effort underway to add Marcellus acreage via leasing and partnering arrangements − Currently completing and testing Lower Huron wells in West Virginia; Marcellus timing of drilling TBD • Woodford / Caney Shale − Located in the Arkoma and Anadarko Basins in Oklahoma − Approximately 40,000 net acres with net unrisked reserve potential of ~ 200 Bcfe − Plans to drill up to 4 exploratory wells in 2008 • Fayetteville Shale − Located in the Arkoma Basin primarily in Pope County, Arkansas − Approximately 14,500 net acres − Currently testing acreage through drilling to determine whether to proceed in the play – results have improved over the last few wells • Bakken Shale − Oil play located in the Williston Basin in Dunn County, North Dakota − Approximately 65,000 (39,000 net) acres with net unrisked reserve potential in excess of 100 Bcfe − Plans to drill up to 2 exploratory wells in 2008 • Lower Bossier Shale − Located in Harrison and Panola Counties in east Texas − Approximately 46,000 (40,000 net) acres with net unrisked reserve potential of ~ 800 Bcfe − Vertical completions have confirmed stabilized flow rates up to 300 Mcf/d − Plans to spud first exploratory horizontal well in first quarter of 2008 9

PENN VIRGINIA Industry: Devonian / Marcellus Shale CORPORATION • Technically recoverable resource: 24 Tcf − Production primarily due to natural fractures − Primary producing interval is organically rich Lower Huron (Devonian) – 30 to 200 net feet − Annual Devonian Shale production ~ 120 Bcf with cumulative production ~ 3Tcf − Historically exploited with vertical wells − Horizontal drilling has increased potential − Mature areas may benefit from downspacing and horizontal drilling • Marcellus is the “new” Appalachian shale play Sunbury Shale Sunbury Shale − Deepest section of the Devonian Shale Upper Huron Shale Upper Huron Shale Lower Huron Shale Lower Huron Shale − Generally thickest from SW to NE PA but also deeper with the right TOC’s especially in NE PA − Proximity to thrust belt is probably important Cleveland Shale Cleveland Shale − Significant competition for acreage Rhinestreet Shale Rhinestreet Shale • Exploratory opportunities exist in both Marcellus Shale Marcellus Shale shallower and deeper organic shales (i.e. Utica and Sunbury) 10
