Certain statements contained herein that are not descriptions of historical facts are “forward‐looking” statements within the meaning of Section 27A of the Securities
Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Because such statements include risks, uncertainties and contingencies,
actual results may differ materially from those expressed or implied by such forward‐looking statements. These risks, uncertainties and contingencies include, but are
not limited to, the following: the volatility of commodity prices for natural gas, natural gas liquids (NGLs) and oil; our ability to develop, explore for, acquire and replace
oil and gas reserves and sustain production; any impairments, write‐downs or write‐offs of our reserves or assets; the projected demand for and supply of natural gas,
NGLs and oil; reductions in the borrowing base under our revolving credit facility; our ability to contract for drilling rigs, supplies and services at reasonable costs; our
ability to obtain adequate pipeline transportation capacity for our oil and gas production at reasonable cost and to sell the production at, or at reasonable discounts to,
market prices; the uncertainties inherent in projecting future rates of production for our wells and the extent to which actual production differs from estimated proved
oil and gas reserves; drilling and operating risks; our ability to compete effectively against other independent and major oil and natural gas companies; uncertainties
related to expected benefits from acquisitions of oil and natural gas properties; environmental liabilities that are not covered by an effective indemnity or insurance;
the timing of receipt of necessary regulatory permits; the effect of commodity and financial derivative arrangements; our ability to maintain adequate financial
liquidity and to access adequate levels of capital on reasonable terms; the occurrence of unusual weather or operating conditions, including force majeure events; our
ability to retain or attract senior management and key technical employees; counterparty risk related to their ability to meet their future obligations; changes in
governmental regulation or enforcement practices, especially with respect to environmental, health and safety matters; uncertainties relating to general domestic and
international economic and political conditions; and the other risks, uncertainties and contingencies set forth in PVA’s Annual Report on Form 10‐K for the fiscal year
ended December 31, 2010.
Additional information concerning these and other factors can be found in our press releases and public periodic filings with the U.S. Securities and Exchange
Commission (SEC), including our Annual Report on Form 10‐K for the year ended December 31, 2010. Readers should not place undue reliance on forward‐looking
statements, which reflect management’s views only as of the date hereof. We undertake no obligation to revise or update any forward‐looking statements, or to make
any other forward‐looking statements, whether as a result of new information, future events or otherwise.
Oil and Gas Reserves
Effective January 1, 2010, the SEC permits oil and gas companies, in their filings with the SEC, to disclose not only “proved” reserves, but also “probable” reserves and
“possible” reserves. As noted above, statements of reserves are only estimates and may not correspond to the ultimate quantities of oil and gas recovered. Any
reserve estimates provided in this presentation that are not specifically designated as being estimates of proved reserves may include estimated reserves not
necessarily calculated in accordance with, or contemplated by, the SEC’s latest reserve reporting guidelines. Investors are urged to consider closely the disclosure in
PVA’s Annual Report on Form 10‐K for the fiscal year ended December 31, 2010, available from PVA at Four Radnor Corporate Center, Suite 200, Radnor, PA 19087
(Attn: Investor Relations). You can also obtain this report from the SEC by calling 1‐800‐SEC‐0330 or from the SEC’s website at www.sec.gov.
Definitions
Proved reserves are those estimated quantities of oil and gas that geological and engineering data demonstrate with reasonable certainty to be economically
producible in future years from known oil and gas reservoirs under existing economic and operating conditions and government regulation prior to the expiration of the
contracts providing the right to operate, unless renewal of such contracts is reasonably certain. Probable reserves are those additional reserves that are less certain to
be recovered than proved reserves, but which are more likely than not to be recoverable (there should be at least a 50% probability that the quantities actually
recovered will equal or exceed the proved plus probable reserve estimates). Possible reserves are those additional reserves that are less certain to be recoverable than
probable reserves (there should be at least a 10% probability that the total quantities actually recovered will equal or exceed the proved plus probable plus possible
reserve estimates). “3P” reserves refer to the sum of proved, probable and possible reserves. Estimated ultimate recovery (EUR) is the sum of reserves remaining as of
a given date and cumulative production as of that date.

3. PVA Overview
• PVA is positioned in a number of prominent oil and gas plays in the U.S.
• Active in the Eagle Ford Shale, Granite Wash, and Marcellus Shale
• Significant HBP positions in the Cotton Valley, Haynesville Shale, Selma Chalk, and Appalachia
• PVA is executing a strategy of growth in oil and NGL rich plays
• 2010 and 2011 have been transformational years, diversifying our portfolio
• Initial well in the Eagle Ford Shale in February of this year and up to 34 wells planned for 2011
• Continuing to add to drilling inventory
• PVA is financially sound
• Ample liquidity to fund 2011 and 2012 drilling program
• Very little drawn on the revolver with a $380 million borrowing base
• No material debt maturities in the next five years
• High rate of return projects are increasing cash flow, borrowing base and liquidity
3

4. PVA’s Growth Strategy is Sound
Cash Flow Ramp Expected, Along With Higher Oil/Liquids Reserves and Production
• “Gas‐to‐Oil” transition underway
• Built Eagle Ford position from initial 4,000 acres to current 14,000 acres in one year
• Grown oil/NGL production from 2,461 Bbls/day in Q210 to 5,187 Bbls/day in Q211 (+111%)
• Rated among the highest‐return drillers in 2010; 2011 should be similar due to Eagle Ford returns
• Other oily / liquids‐rich plays include the horizontal Cotton Valley and Granite Wash
– Current PV‐10 value for producing wells in both of these plays of $316MM1
• Substantial core gas assets retained for eventual gas price recovery
• Haynesville Shale in east Texas, Selma Chalk in Mississippi and Appalachia
– Largely HBP with current PV‐10 value for producing wells of $414MM1
• Divestitures increase margins and operational focus, enhance liquidity
• Nearly $530MM in non‐core asset divestitures from 2009 to 2011
• Efforts continue to expand oil/liquids reserves and drilling inventory
• May include new play types in new areas
• Expected growth in cash flows should drive recovery in equity valuation

• New credit facility reflects high quality assets
• 5‐year maturity at a 0.5% lower interest rate
• Maximum leverage of up to 4.5x through June 2013
• Non‐core asset sales further bolster liquidity
• Closed $30.5MM sale of primarily Arkoma assets
• Will consider asset sales / partnering opportunities
• Will reinvest proceeds into oil / liquids inventory
1 – Pro forma for sale of non‐core Mid‐Continent gas assets; pro forma liquidity at 6/30/11 of $440MM
is comprised of a pro forma and undrawn borrowing base of $380MM and approximately $60MM
of cash; future ability to borrow under the revolver will be subject to a maximum leverage ratio of 1
4.5x (through 6/30/13) and 4.0x (from 9/30/13 through 6/30/16) net debt‐to‐EBITDAX, as well as
future borrowing base amounts 5

6. Cash Flow Growth is Expected
CFPS and EBITDAX Growth in Line With Most Peers Who Have Smaller Bases to Grow From
• Expected growth in cash flow is in line with peers through 20121
• Growth is fully‐funded
• Expected growth in EBITDAX1 will drive additional debt capacity and increases in the
borrowing base during 2012 and beyond

8. What is Our Response?
Focus on Drilling the Eagle Ford and Look to Expand Our Oil Inventory in the Near‐Term
 Continue to increase oil and liquids exposure
• 40‐45% of 4Q11 production vs. 18% in 2010; cash flows expected to accelerate
• Eagle Ford‐driven, with goal to add more Eagle Ford / other oily inventory
 Retain long‐term optionality of core gas assets
• E. Texas, Mississippi and Appalachia – largely HBP; wait on gas prices
• Continued testing of Marcellus Shale position, with or without a partner
 Further build liquidity and maintain solid financial position
• No maturities for five years and ample liquidity to fund CAPEX until free cash flow positive
• Continuing to drill and prove up reserves increases cash flow, borrowing base value and
liquidity
 Look at the value:
• Proved developed PV‐10 value of $730MM pays debt off plus $3.56 per share of value
• Implied remaining equity value of $103MM for 14,000 acres of prime Eagle Ford acreage,
55,000 of Marcellus acreage, all company PUDs and 3P value
• Trading at 1.2x 2012E cash flow per share and 2.8x EBITDAX
