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 arenot limited to, the following: the volatility of commodity prices for natural gas, NGLs and oil; our ability to develop, explore for and replace oil and gas reserves andsustain production; our ability to generate profits or achieve targeted reserves in our development and exploratory drilling and well operations; 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 revolvingcredit facility; our ability to contract for drilling rigs, supplies and services at reasonable costs; our ability to obtain adequate pipeline transportation capacity for our oiland 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 ofproduction for our wells and the extent to which actual production differs from estimated proved oil and gas reserves; drilling and operating risks; our ability tocompete effectively against other independent and major oil and natural gas companies; our ability to successfully monetize select assets and repay our debt; leaseholdterms expiring before production can be established; environmental liabilities that are not covered by an effective indemnity or insurance; the timing of receipt ofnecessary regulatory permits; the effect of commodity and financial derivative arrangements; our ability to maintain adequate financial liquidity and to accessadequate levels of capital on reasonable terms; the occurrence of unusual weather or operating conditions, including force majeure events; our ability to retain orattract senior management and key technical employees; counterparty risk related to their ability to meet their future obligations; changes in governmental regulationor enforcement practices, especially with respect to environmental, health and safety matters; uncertainties relating to general domestic and international economicand political conditions; and other risks set forth in our filings with the U.S. Securities and Exchange Commission (SEC).

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. Anyreserve estimates provided in this presentation that are not specifically designated as being estimates of proved reserves may include estimated reserves notnecessarily calculated in accordance with, or contemplated by, the SEC’s latest reserve reporting guidelines. Investors are urged to consider closely the disclosure inPVA’s Annual Report on Form 10‐K for the fiscal year ended December 31, 2011, which is available from PVA at Four Radnor Corporate Center, Suite 200, Radnor, PA19087 (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 quantities of oil and gas which, by analysis of geosciences and engineering data, can be estimated with reasonable certainty to beeconomically producible from a given date forward, from known reservoirs, and under existing economic conditions, operating methods and government regulationbefore the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether theestimate is a deterministic estimate or probabilistic estimate. Probable reserves are those additional reserves that are less certain to be recovered than provedreserves, but which are as likely than not to be recoverable (there should be at least a 50% probability that the quantities actually recovered will equal or exceed theproved plus probable reserve estimates). Possible reserves are those additional reserves that are less certain to be recoverable than probable reserves (there should beat least a 10% probability that the total quantities actually recovered will equal or exceed the proved plus probable plus possible reserve estimates). “3P” reserves referto 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 productionas of that date.

PVA’s Catalysts / Challenges

• Challenges• Managing liquidity in light of our higher cost of capital 

• Expansion of oily drilling inventory

• Very capital intensive industry

• Catalysts• Eagle Ford exploratory success in Lavaca County, TX

• Strong Eagle Ford development drilling results 

• Success in lowering Eagle Ford drilling and completion costs

• Increasing Eagle Ford production, margins and cash flows

• Granite Wash sale would increase liquidity and reduce leverage 

• Retained Mid‐Continent oil prospect expected to be drilled and completed in 3Q12

• Attractive natural gas asset base that is primarily HBP

Options to Build Financial Liquidity

Business Strategy

• Commenced our “Gas‐to‐Oil” transition in mid‐2010• Built Eagle Ford position from initial 6,800 net acres to nearly 25,000 net acres currently

– Up to approximately 250 well locations– Includes acreage and locations expected to be earned in AMI in Lavaca County

• Grew oil/NGL production from 2,461 Bbls/day in 2Q10 to 8,387 Bbls/day in 1Q12 (+241%)– Up 17% from 7,194 Bbls/day in 4Q11– 42% of total production and 82% of product revenues– Daily oil production alone grew 23% from 4Q11 to 1Q12

• Other oily / liquids‐rich plays include the Cotton Valley and other prospects 

• Retain substantial core gas assets for eventual gas price recovery• Haynesville Shale, Cotton Valley, Mississippi Selma Chalk and Marcellus Shale

• Make selective divestitures to improve operational focus and liquidity• Have launched Granite Wash asset sale process

• Continue to expand oil and liquids reserves and drilling inventory• Viola Lime oil prospect: ~10K net acres; will test in 2012; potential to expand• MS Lime oil prospect: ~6K net acres; nearby production and testing looks encouraging

• Continue to grow oil and liquids production and cash flows• Eagle Ford drilling emphasis in 2012• Continued focus on optimizing drilling, completion and operating costs
