7.25% Senior Notes due 2019

Interest payable April 15 and October 15

The notes will mature on April 15, 2019. Interest on the notes will accrue from April 13, 2011 and the first payment will be on October 15, 2011.

We may redeem some or all of the notes at any time on or after April 15, 2015 at the redemption prices set forth beginning on page S-32 and prior to such date at a “make-whole” redemption price, in each case, plus accrued and unpaid interest, if any, to the date of redemption. We may also redeem up to 35% of the notes prior to April 15, 2014 with cash proceeds we receive from certain equity offerings. If we sell certain assets and do not reinvest the proceeds or repay senior indebtedness or if we experience specific kinds of changes of control, we must offer to repurchase the notes.

The notes will be our senior unsecured obligations and will rank equally with all of our other unsecured senior indebtedness that is not by its terms subordinated to the notes. The notes will be senior to our existing and future subordinated indebtedness. The notes will be effectively subordinated to all of our secured indebtedness (including our revolving credit facility) to the extent of the collateral securing such indebtedness.

The obligations under the notes will be fully and unconditionally guaranteed by our subsidiaries that guarantee our indebtedness under our revolving credit facility. The guarantee of any subsidiary will be released when such subsidiary no longer has outstanding or guarantees certain specified indebtedness, when such subsidiary is no longer a subsidiary of ours or when such subsidiary is designated as an unrestricted subsidiary under the terms of the indenture. The guarantees will be equal in right of payment with the existing and future unsecured senior indebtedness of the guarantors, including the guarantees of our revolving credit facility, and will rank senior to the future subordinated indebtedness of the guarantors. The guarantees will be effectively junior to all existing and future secured indebtedness of the guarantors, including guarantees of our revolving credit facility to the extent of the collateral securing such indebtedness.

Investing in the notes involves risks. See “Risk factors” beginning on page S-13.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these notes or determined if this prospectus supplement or the accompanying prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

About this prospectus supplement

This document is in two parts. The first part is this prospectus supplement and the documents incorporated by reference herein, which, among other things, describes the specific terms of this offering. The second part, the accompanying prospectus and the documents incorporated by reference therein, gives more general information, some of which may not apply to this offering. If the description of this offering varies between this prospectus supplement and the accompanying prospectus, you should rely on the information in this prospectus supplement.

You should rely only on the information contained in or incorporated by reference in this prospectus supplement, the accompanying prospectus and any related free writing prospectus. We have not authorized anyone to provide you with different information. We are not and the underwriters are not making an offer to sell these securities in any jurisdiction where the offer or sale is not permitted. You should not assume that the information contained in this prospectus supplement or the accompanying prospectus is accurate as of any date other than the date on the front of this prospectus supplement.

Except in the section under the caption “Description of notes” and unless specified otherwise or the context otherwise requires, all references in this prospectus supplement to “Penn Virginia,” “Issuer,” “us,” “we,” “our” or “our Company” are to Penn Virginia Corporation, a Virginia corporation, together with its consolidated subsidiaries.

We expect that the delivery of the notes will be made against payment therefor on or about April 13, 2011, which is the sixth business day following the date of pricing of the notes (such settlement cycle being herein referred to as “T+6”). Under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in three business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes on the date of pricing of the notes or during the next succeeding two business days will be required, by virtue of the fact that the notes initially will settle in T+6, to specify an alternate settlement cycle at the time of any such trade in order to prevent failed settlement and should consult their own advisors.

Forward-looking statements

Some of the information included in this prospectus supplement, the accompanying prospectus and the documents we incorporate by reference herein and therein contain “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). These statements use forward-looking words such as “may,” “will,” “should,” “could,” “achievable,” “anticipate,” “believe,” “expect,” “estimate,” “project” or other words and phrases of similar meaning. These statements discuss goals, intentions and expectations as to future trends, plans, events, results of operations or financial condition or state other “forward-looking” information. A forward-looking statement may include a statement of the assumptions or bases underlying the forward-looking statements. We believe we have chosen these assumptions or bases in good faith and that they are reasonable. However, we caution you that assumed facts or bases almost always vary from actual results, and the differences between assumed facts or bases and actual results can be material, depending on the circumstances. When considering forward-looking statements, you should keep in mind the cautionary statements in this prospectus supplement, the accompanying prospectus and the documents we have incorporated by reference herein and therein, including in our Annual Report on Form 10-K for the year ended December 31, 2010 (our “2010 Annual Report”). These statements reflect our current views with respect to future events and are subject to various risks, uncertainties and assumptions, including, but not limited, to:

• 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 existing revolving credit facility (our “Revolver”);

• 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;

S-iii

• 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

• other risks set forth in Item 1A of our 2010 Annual Report.

Additional information concerning these and other factors can be found in our press releases and public periodic filings with the Securities and Exchange Commission (the “SEC”). Many of the factors that will determine our future results are beyond the ability of management to control or predict. Readers should not place undue reliance on forward-looking statements, which reflect management’s views only as of the date hereof. All forward-looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by the cautionary statements in this section and elsewhere in this prospectus supplement and the accompanying prospectus and in the documents incorporated herein and therein by reference. Other than as required under the securities laws, 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, changes in expectations or otherwise.

Summary

This summary highlights selected information contained elsewhere in this prospectus supplement, the accompanying prospectus and in the documents we incorporate by reference herein and therein. This summary is not complete and does not contain all of the information that you should consider before deciding whether or not to invest in the notes. For a more complete understanding of our Company and this offering, we encourage you to read this entire document, including “Risk factors,” the financial and other information incorporated by reference in this prospectus supplement and the accompanying prospectus and the other documents to which we have referred. The notes we will issue in this offering will be guaranteed by each of the subsidiaries of Penn Virginia Corporation that guarantee our indebtedness under our revolving credit facility.

Penn Virginia Corporation

We are an independent oil and gas company engaged primarily in the exploration, development and production of natural gas and oil in various domestic onshore regions of the United States. We have a geographically diverse asset base with core areas of operations in Texas, Appalachia, the Mid-Continent and Mississippi regions. Our operations include both conventional and unconventional developmental drilling opportunities, as well as some exploratory prospects.

The year 2010 was transformational for us. In June 2010, we disposed of our remaining ownership interests in Penn Virginia Resource Partners, L.P. (“PVR”) and Penn Virginia GP Holdings, L.P. (“PVG”). We transitioned to a “pure play” E&P company, and we began, and are continuing, to refocus our operations on drilling in economically attractive natural gas, oil and NGL-rich areas. To this end, we disposed of our Gulf Coast assets and exited the area in January 2010, and since then we invested approximately $160 million to increase our leaseholds in potentially higher return prospects in the Mid-Continent and the Marcellus Shale and to establish a position in the oil rich Eagle Ford Shale. We have also suspended drilling on our acreage located in east Texas and Mississippi, which is primarily lower return, dry gas and held by production, with the option to resume drilling there when natural gas prices justify renewed investment.

Prior to June 2010, we indirectly owned partner interests in PVR, a publicly traded limited partnership formed by us in 2001 that is engaged in the coal and natural resource management and natural gas midstream businesses, principally through our ownership of general and limited partner interests in PVG, a publicly traded limited partnership formed by us in 2006.

Our oil and gas business

We have a geographically diverse asset base with core areas of operation in Texas, Appalachia, the Mid-Continent and Mississippi. As of December 31, 2010, we had proved natural gas and oil reserves of approximately 942 billion cubic feet equivalent (“Bcfe”), of which 79% were natural gas and 53% were proved developed, with an SEC pre-tax PV-10 value of $878.1 million and standardized measure of discounted future net cash flows of $641.4 million. See “—Summary reserve, production and operating data” for a reconciliation of PV-10 to standardized measure of discounted future net cash flows.

S-1

For the year ended December 31, 2010, we had average daily production of 128.5 million cubic feet equivalent (“MMcfe”) per day (excluding the average daily production of our Gulf Coast properties, which we sold in January 2010). Our properties generally have long reserve lives and reasonably stable and predictable well production characteristics with a ratio of proved reserves to production of approximately 20 years.

The following table sets forth by region the estimated quantities of proved reserves, production and reserves to production ratio:

	Proved reserves as of December 31, 2010								Average daily production(1)
Region	Proved reserves (Bcfe)		% Total proved reserves		% Proved developed		Reserves to production ratio (in years)		Year ended December 31, 2010 (MMcfe)
Texas		448		48%		38%		33.1		37.1
Appalachia		120		13%		95%		11.5		28.5
Mid-Continent		192		20%		60%		12.5		42.0
Mississippi		182		19%		57%		23.8		20.9
Total		942		100%		53%		20.1		128.5

(1) Does not include data for our Gulf Coast properties, which we sold in a transaction that closed on January 29, 2010. During the period from January 1, 2010 to January 29, 2010, the average daily production from these properties was 0.8 MMcfe.

The following table sets forth certain information regarding our net acres of leasehold interests:

	As of March 31, 2011
	Net acres (in thousands)		% Developed		% Undeveloped
Eagle Ford Shale		14.9		37%		63%
Marcellus Shale		56.1		1%		99%
Mid-Continent		128.5		62%		38%
Other		846.6		74%		26%
Total		1,046.1		68%		32%

Business strengths

High quality asset base in attractive regions. We own and operate a geographically diversified reserve base, which we believe reduces potential operational and reserve risks. Our properties are located in geological basins in Texas, the Mid-Continent, Appalachia and Mississippi and provide a multi-year inventory of development drilling and exploration projects. Our proved reserves are characterized by long-lived, lower-risk, predictable production profiles.

Track record of growth at low-cost. Between January 1, 2006 and December 31, 2010, we drilled 885 gross wells with an average success rate of 96% and replaced a weighted average of 326% of our proved reserves each year through the drill-bit. During the same five-year period, our proved reserves grew at a compound average growth rate of approximately 23% per year. We believe our finding and development costs compare favorably to those of our competitors.

Exposure to significant unconventional resources. Our primary operations for 2011 are focused on the Eagle Ford Shale, Marcellus Shale and Mid-Continent. We have approximately 199,000 net acres across these regions. During 2011, we plan to drill 72 gross wells in these areas. As of December 31, 2010, we did not report any proved reserves for the Eagle Ford or Marcellus Shales since we are drilling our first horizontal wells in these areas during 2011.

S-2

Experienced management and technical teams. Our senior management team has an average of over 25 years of industry experience and is supported by technical and operating personnel who also have substantial industry experience and expertise. Over the past five years, the management team and their staff have increased our proved reserves from approximately 437 Bcfe at December 31, 2006 (excluding our Gulf Coast properties) to approximately 942 Bcfe at December 31, 2010 and have increased our production from approximately 25 Bcfe in 2006 (excluding our Gulf Coast properties) to approximately 47 Bcfe in 2010.

Business strategy

Focus on higher margin projects. We intend to focus on higher margin natural gas, oil and NGLs development projects in the Eagle Ford Shale, Marcellus Shale and Mid-Continent. Approximately 95% of our planned capital expenditures in 2011 are dedicated to these areas of operation. This strategy reflects the ongoing weakness in natural gas prices and the relative strength in oil and NGL prices. In 2011, we anticipate 25% to 30% of our total production will consist of oil and NGLs as compared to approximately 18% in 2010.

Grow primarily through unconventional resource drilling. We are applying horizontal drilling technology in our three focus areas, the Eagle Ford Shale, Marcellus Shale and Mid-Continent, which we believe will maximize reserve additions, production rates and rates of return. In 2011, we plan to allocate up to $225 million (approximately 70%) and $65 million (approximately 20%) of our planned 2011 oil and gas capital expenditures to development and exploratory drilling and related activities, most of which will be in these three areas. We feel exploratory drilling provides operational balance and future development growth opportunities.

Pursue selective leasehold and producing property acquisition opportunities in our core areas. Our experienced management team and technical professionals consistently look for opportunities to extend our leasehold acreage, especially in our focus areas. Adding acreage to our leasehold position increases the number of drilling prospects necessary to continue to grow our reserves and production. We anticipate allocating up to $30 million, or approximately 10%, of our 2011 oil and gas capital expenditures to leasehold acquisitions.

Redeploy cash raised from the sale of non-core assets into our focus areas. In 2010, we realized net proceeds of $365 million through the sale of certain non-core assets, including our remaining interests in PVG. We reinvested a significant portion of these net proceeds in 2010 through drilling and completion activities, leasehold acquisitions and other operational expenditures, and we expect to use our remaining proceeds in a similar fashion during 2011.

Manage risk exposure through an active hedging program. We actively manage our exposure to commodity price fluctuations by hedging the commodity price risk for our expected production through the use of derivatives, typically costless collar and swap contracts. The level of our hedging activity and duration of the instruments employed depend upon our cash flows at risk, available hedge prices and our operating strategy. For 2011, we have hedged over 50% of our estimated natural gas production, at average floor and ceiling prices of $5.22 and $6.47 per million British thermal units, respectively.

Maintain a strong financial position. We expect to continue to use our substantial cash flows from operations to fund the majority of our capital requirements, including working capital, supplemented as needed by debt financing, equity issuances and the sale of non-core assets while maintaining a conservative capital structure.

Recent developments

Tender offer for convertible notes

On March 8, 2011, we commenced a cash tender offer (the “Tender Offer”) for any and all of our outstanding 4.50% Convertible Senior Subordinated Notes due 2012 (our “2012 Convertible Notes”). The Tender Offer is scheduled to expire on April 11, 2011 at 12:00 midnight, New York City time, unless extended. Of the $230 million aggregate principal amount of our 2012 Convertible Notes outstanding prior to the commencement of the Tender Offer, approximately $225 million aggregate principal amount have been validly tendered and not validly withdrawn as of the close of business on April 4, 2011. 2012 Convertible Notes tendered pursuant to the Tender Offer may be withdrawn by the holder at any time prior to the expiration date of the Tender Offer. The net proceeds of this offering will be used to fund the purchase of our 2012 Convertible Notes validly tendered and not validly withdrawn prior to the expiration date pursuant to the Tender Offer. See “Use of proceeds.”

Consent solicitation relating to senior notes

On March 24, 2011, we initiated a consent solicitation (the “Consent Solicitation”) from holders of our existing 10.375% Senior Notes due 2016 (our “2016 Senior Notes”) for an amendment (the “Proposed Amendment”) to the indenture governing the 2016 Senior Notes that would permit us to purchase, repurchase, redeem, defease or otherwise acquire for value our 2012 Convertible Notes. The Consent Solicitation expired on April 1, 2011 at 5:00 p.m., New York City time. Of the $300 million aggregate principal amount of our 2016 Senior Notes outstanding on the record date with respect to the Consent Solicitation, holders representing $294.2 million aggregate principal amount of our 2016 Senior Notes consented to the Proposed Amendment.

Corporate information

We were founded in 1882 and are a Virginia corporation. Our corporate headquarters and principal executive offices are located at Four Radnor Corporate Center, Suite 200, 100 Matsonford Road, Radnor, Pennsylvania 19087, and our telephone number is (610) 687-8900. We maintain a website at http://www.pennvirginia.com.

The offering

The summary below describes the principal terms of the notes. Certain of the terms and conditions described below are subject to important limitations and exceptions. The “Description of notes” section of this prospectus supplement, together with the “Description of Debt Securities” section in the accompanying prospectus, contains a more detailed description of the terms and conditions of the notes. For purposes of this summary of the notes, references to the “Company,” “issuer,” “us,” “we” and “our” refer only to Penn Virginia Corporation and do not include our subsidiaries.

Issuer Penn Virginia Corporation

Securities $300,000,000 aggregate principal amount of 7.25% Senior Notes due 2019

Maturity April 15, 2019

Interest payment dates Interest is payable on the notes on April 15 and October 15 of each year, beginning on October 15, 2011. Interest will accrue from April 13, 2011.

Optional redemption We may, at our option, redeem all or part of the notes at any time prior to April 15 , 2015, at a make-whole price, and on or after April 15, 2015, at fixed redemption prices, in each case, plus accrued and unpaid interest, if any, to the date of redemption, as described under “Description of notes—Optional redemption.” In addition, prior to April 15, 2014, we may, at our option, redeem up to 35% of the notes with the proceeds of certain equity offerings.

Ranking The notes will be our general unsecured, senior obligations. Accordingly, they will rank:

• senior in right of payment to all of our existing and future indebtedness that is expressly subordinated to the notes, including any 2012 Convertible Notes not validly tendered pursuant to the Tender Offer;

• equal in right of payment with any of our existing and future unsecured indebtedness that is not by its terms subordinated to the notes, including our outstanding 2016 Senior Notes;

• effectively junior to our existing and future secured indebtedness, including indebtedness under our Revolver, to the extent of our assets constituting collateral securing such indebtedness; and

• structurally subordinated to all existing and future indebtedness and other liabilities (other than indebtedness and liabilities owed to us) of our non-guarantor subsidiaries.

As of December 31, 2010, after giving effect to the issuance and sale of the notes and the application of the estimated net proceeds therefrom as set forth under “Use of proceeds” and assuming that $218.5 million of our 2012 Convertible Notes had been validly tendered and not validly withdrawn pursuant to the Tender Offer

S-5

(which represents 95% of the aggregate outstanding principal amount of our 2012 Convertible Notes), we would have had total indebtedness of $611.5 million, which excludes $8.3 million of unamortized original issue discount, the $0.7 million in letters of credit outstanding under our Revolver and availability of up to $299.3 million under our Revolver.

Subsidiary guarantees The notes initially will be jointly and severally guaranteed on a senior unsecured basis by certain of our existing domestic oil and gas subsidiaries. In the future, the guarantees may be released or terminated under certain circumstances. Each subsidiary guarantee will be a general unsecured obligation of the subsidiary guarantor and will rank:

• senior in right of payment to all existing and future subordinated indebtedness of that subsidiary guarantor;

• equal in right of payment to all existing and future senior unsecured indebtedness of that subsidiary guarantor;

• effectively junior to that subsidiary guarantor’s existing and future secured indebtedness, including its guarantee of indebtedness under our Revolver, to the extent of the value of the assets of such subsidiary guarantor constituting collateral securing such indebtedness; and

• structurally junior to the indebtedness and other liabilities of our non-guarantor subsidiaries.

Certain of our subsidiaries will not guarantee the notes. At December 31, 2010, our non-guarantor subsidiaries had de minimis indebtedness and other liabilities, which indebtedness would rank structurally senior to the notes and related guarantees.

Covenants The indenture governing the notes will contain covenants that, among other things, limit our ability and the ability of our restricted subsidiaries to:

• incur additional debt;

• make certain investments or pay dividends or distributions on our capital stock or purchase, redeem or retire capital stock;

• sell assets, including capital stock of our restricted subsidiaries;

• restrict dividends or other payments by restricted subsidiaries;

• create liens that secure debt;

• enter into transactions with affiliates; and

• merge or consolidate with another company.

These covenants are subject to a number of important limitations and exceptions that are described later in this prospectus supplement under the caption “Description of notes—Certain covenants.” In addition, certain of the covenants listed above will terminate before the notes mature if both of the specified rating agencies assign the

S-6

notes an investment grade rating in the future and no events of default exist under the indenture. Any covenants that cease to apply to us as a result of achieving investment grade ratings will not be restored, even if the credit ratings assigned to the notes later fall below investment grade.

Change of control offer If we experience certain kinds of changes of control, we must give holders of the notes the opportunity to sell us their notes at 101% of their principal amount, plus accrued and unpaid interest. However, in such an event, we might not be able to pay you the required repurchase price for the notes you present to us because we might not have sufficient funds available at that time, or the terms of our Revolver may prevent us from applying funds to repurchase the notes.

No public market The notes are a series of securities for which there is currently no established trading market. The underwriters have advised us that they presently intend to make a market in the notes. However, you should be aware that they are not obligated to make a market and may discontinue their market-making activities at any time without notice. As a result, a liquid market for the notes may not be available if you try to sell your notes. We do not intend to apply for a listing of the notes on any securities exchange or any automated dealer quotation system.

Use of proceeds We intend to use a portion of the net proceeds from this offering to fund the Tender Offer described under “—Recent developments—Tender offer for convertible notes.” Any remaining net proceeds will be used to provide additional working capital for general corporate purposes. Certain of the underwriters or their affiliates are holders of our 2012 Convertible Notes and, accordingly, they will receive a portion of the net proceeds of this offering in connection with the Tender Offer.

Form The notes will be represented by registered global securities registered in the name of Cede & Co., the nominee of the depositary, The Depository Trust Company (“DTC”). Beneficial interests in the notes will be shown on, and transfers will be effected through, records maintained by DTC and its participants.

Risk factors See “Risk factors” beginning on page S-13 of this prospectus supplement for important information regarding us and an investment in the notes.

(2) EBITDAX represents net income, on a consolidated basis, before income tax expense, interest expense, depreciation, depletion and amortization, impairment of oil and gas properties, non-cash derivative loss (gain), loss (gain) on sale of property and equipment, gain on other asset sales, non-cash compensation expense and exploration expenses. Adjusted EBITDAX represents EBITDAX plus cash distributions we received in respect of our partner interest in PVG and PVR. EBITDAX and Adjusted EBITDAX are not measures calculated in accordance with generally accepted accounting principles (“GAAP”). EBITDAX and Adjusted EBITDAX should not be considered as alternatives to net income, income before taxes, net cash flow from operating activities or any other measure of financial performance presented in accordance with GAAP. We believe that EBITDAX is a widely accepted financial indicator of a company’s ability to incur and service debt and to fund capital expenditures. Because EBITDAX is commonly used in the oil and gas industry, we believe it is useful in evaluating our ability to meet our interest obligations in connection with this offering. EBITDAX and Adjusted EBITDAX calculations may vary among entities, so our computation of EBITDAX and Adjusted EBITDAX may not be comparable to EBITDAX and Adjusted EBITDAX, or similar measures, of other entities. In evaluating EBITDAX and Adjusted EBITDAX, we believe that investors should consider, among other things, the amount by which EBITDAX and Adjusted EBITDAX exceed interest costs, how EBITDAX and Adjusted EBITDAX compare to payments of principal on debt and how EBITDAX and Adjusted EBITDAX compare to capital expenditures for each period. The following table provides a reconciliation of net income to EBITDAX and to Adjusted EBITDAX:

Summary reserve, production and operating data

Estimates of our oil and natural gas reserves and present values as of and for the years ended December 31, 2010, 2009 and 2008 are derived from reserve reports prepared by Wright & Company, Inc. Guidelines established by the SEC regarding the present value of future net cash flows were utilized to prepare these estimates. Estimates of reserves and their value are inherently imprecise and are subject to constant revision and change, and they should not be construed as representing the actual quantities of future production or cash flows to be realized from oil and natural gas properties or the fair market value of such properties.

The following table sets forth summary data with respect to estimated proved reserves and future net cash flows on a historical basis as of and for the periods presented:

	As of December 31,
($ in thousands, except where noted)	2010		2009		2008

Oil ($/Bbl)	$	79.43	$	61.18	$	44.60

(1) Calculated by dividing year-end reserves by annual production rates. This methodology implies that reserves are produced ratably over the reserve life indicated. Actual production rates for new wells tend initially to increase to peak production and thereafter to decline at an initially accelerated rate before moderating to decrease much more gradually over the majority of the well’s productive life.

(2) PV-10 is the present value of estimated future revenues to be generated from the production of proved reserves, before income taxes, net of estimated production and future development costs, using prices and costs as of the date of estimation without future escalation, without giving effect to financial hedging activities, non-property related expenses such as general and administrative expenses, debt service and depreciation, depletion and amortization, and discounted using an annual discount rate of 10%. Standardized measure is the present value of estimated future cash inflows from proved natural gas and oil reserves, less future development and production costs and future income tax expenses, discounted at 10% per annum to reflect timing of future cash flows and using the same pricing assumptions as are used to calculate PV-10. Standardized measure differs from PV-10 because standardized measure includes the effect of future income taxes.

PV-10 is considered a non-GAAP measure. We believe the presentation of the PV-10 value is relevant and useful to our investors because it presents the discounted future net cash flows attributable to our proved reserves before taking into account corporate income taxes. We believe investors and creditors utilize our PV-10 value as a basis for comparison of the relative size and value of our reserves to other companies. Neither PV-10 value nor standardized measure reflects the impact of financial hedging transactions. The following reconciles our PV-10 value to our standardized measure:

Standardized measure	$	641,419	$	524,771	$	729,401

(3) Natural gas and oil prices were based on sales prices per thousand cubic feet (“Mcf”) and standard barrel of 42 U.S. gallons liquid volume (“Bbl”) in effect on the applicable date, with the representative price of natural gas adjusted for basis premium and British thermal unit, content to arrive at the appropriate net price.

Risk factors

An investment in the notes is subject to a number of risks. You should carefully consider the following risks, as well as the section entitled “Risk Factors” included in our 2010 Annual Report incorporated herein and therein by reference, as well as the information in the accompanying prospectus and the other documents incorporated herein by reference, in evaluating this investment. If any of these risks actually occur, our business, financial condition or results of operations could suffer.

Risks relating to the offering

After completion of the offering, we will have a significant amount of indebtedness and we may incur additional indebtedness.

At December 31, 2010, we and the guarantors of the notes had an aggregate of approximately $530.0 million of debt outstanding and would have been able to incur an additional $299.3 million (net of $0.7 million of letters of credit) under our Revolver. Assuming that we had completed this offering and that $218.5 million of our 2012 Convertible Notes had been validly tendered and not validly withdrawn pursuant to the Tender Offer (which represents 95% of the aggregate outstanding principal amount of our 2012 Convertible Notes), in each case at December 31, 2010, we and the guarantors of the notes would have had an aggregate of approximately $611.5 million of debt (including the notes) outstanding (excluding $8.3 million of unamortized original issue discount) and would have been able to incur an additional $299.3 million (net of $0.7 million of letters of credit) under our Revolver (after giving effect to the automatic reduction in the borrowing base under the Revolver resulting from the issuance of the notes). We and our subsidiaries may incur additional indebtedness in the future. Subject to certain conditions, the terms of the indenture under which the notes will be issued and our other existing debt instruments do not prohibit us or our subsidiaries from incurring additional indebtedness. Accordingly, should our current debt levels increase, the risks related to the notes and our indebtedness generally that we and our subsidiaries now face could also increase.

Any increase in our level of indebtedness will have several important effects on our future operations, including, without limitation:

• we will have additional cash requirements in order to support the payment of interest on our outstanding indebtedness;

• increases in our outstanding indebtedness and leverage will increase our vulnerability to adverse changes in general economic and industry conditions, as well as to competitive pressure; and

• depending on the levels of our outstanding debt, our ability to obtain additional financing for working capital, capital expenditures, general corporate and other purposes may be limited.

Our ability to service our indebtedness depends on certain financial, business and other factors, many of which are beyond our control.

Our ability to make scheduled payments of principal and interest on our indebtedness or to refinance our debt obligations depends on our future financial condition and operating performance, which will be subject to general economic conditions and to certain financial, business and other factors affecting our consolidated operations, many of which are beyond our

S-13

control. If we are unable to generate sufficient cash flows from operations in the future to service our debt, we may be forced, among other things:

• to seek additional financing in the debt or equity markets;

• to refinance or restructure all or a portion of its indebtedness, including the notes;

• to sell selected assets;

• to reduce or delay planned capital expenditures; or

• to reduce or delay planned operating expenditures.

Such measures might not be successful and might not enable us to service our debt. In addition, any such financing, refinancing or sale of assets might not be available on economically favorable terms.

The indenture governing the notes and our Revolver impose restrictions on our operations and activities, including on our ability to dispose of assets or operations to meet our debt service and other obligations. If we are unable to comply with any of these restrictions or covenants, the trustee or the banks, as appropriate, could cause our debt to become due and payable prior to maturity.

Our Revolver and other debt instruments have restrictive covenants that could limit our financial flexibility.

The indentures related to the notes, our 2016 Senior Notes and our 2012 Convertible Notes and our Revolver contain financial and other restrictive covenants that limit our ability to engage in activities that may be in our long-term best interests. Our ability to borrow under our Revolver is subject to compliance with certain financial covenants, including leverage and interest coverage ratios. Our Revolver includes other restrictions that, among other things, limit our ability to incur indebtedness; grant liens; engage in mergers, consolidations and liquidations; make asset dispositions, restricted payments and investments; enter into transactions with affiliates; and amend, modify or prepay certain indebtedness. The indenture related to the notes will contain limitations on our ability to effect mergers and change of control events, as well as other limitations, including:

• limitations on the declaration and payment of dividends or other restricted payments;

• limitations on incurring additional indebtedness or issuing preferred stock;

• limitations on the creation or existence of certain liens;

• limitations on incurring restrictions on the ability of certain of our subsidiaries to pay dividends or other payments;

• limitations on transactions with affiliates; and

• limitations on the sale of assets.

See “Description of other indebtedness.” Our failure to comply with these covenants could result in an event of default that, if not cured or waived, could result in the acceleration of all of our debts. We do not have sufficient working capital to satisfy our debt obligations in the event of an acceleration of all or a significant portion of our outstanding indebtedness.

The notes are unsecured obligations and will be effectively subordinated to our secured indebtedness.

Our obligations under the notes will not be secured by any of our assets and are and will be effectively subordinated to any of our existing and future secured indebtedness to the extent of

S-14

the collateral securing such secured indebtedness. Accordingly, in the event of our bankruptcy, liquidation or any similar proceeding, holders of the notes will be entitled to payment only after the holders of any of our secured indebtedness have been paid out of the proceeds of the collateral securing such secured indebtedness, together with the accrued and unpaid interest. At December 31, 2010, we and the guarantors of the notes did not have any secured indebtedness outstanding. See “Description of other indebtedness.” The indenture under which the notes will be issued and our other existing debt instruments will permit us, subject to certain limits, to incur additional secured obligations, including up to $525 million of indebtedness under our Revolver (subject to availability under our Revolver), all of which would be secured.

The notes will be structurally subordinated to indebtedness of our non-guarantor subsidiaries.

You will not have any claim as a creditor against any of our non-guarantor subsidiaries, and indebtedness and other liabilities, including trade payables, of those subsidiaries will be effectively senior to your claims against those subsidiaries. Our right to receive any assets of any of our non-guarantor subsidiaries upon their bankruptcy, liquidation or reorganization, and therefore the right of the holders of the notes to participate in those assets, will be effectively subordinated to the claims of those non-guarantor subsidiaries’ creditors, including trade creditors. In addition, even if we are a creditor of any of our non-guarantor subsidiaries, our rights as a creditor would be subordinate to any security interest in the assets of such non-guarantor subsidiary’s subsidiaries and any indebtedness of such non-guarantor subsidiary’s subsidiaries that is senior to that held by us. Certain of our subsidiaries are non-guarantor unrestricted subsidiaries. At December 31, 2010, our non-guarantor subsidiaries had a de minimis amount of outstanding indebtedness and other liabilities. However, the indenture under which the notes will be issued will permit these subsidiaries, so long as they are unrestricted subsidiaries, to incur additional indebtedness without any limitation.

We may not have the ability to raise funds necessary to finance any change of control offer required by the indenture.

If a change of control occurs as described in the section “Description of notes—Change of control,” we would be required to offer to repurchase the notes at 101% of their principal amount together with all accrued and unpaid interest, if any, to the date of purchase. The indenture governing our 2016 Senior Notes contains substantially the same change of control provisions that will be contained in the indenture governing the notes. Our Revolver currently provides that certain change of control events will constitute a default and, in the event of such a default, the holders of such indebtedness could elect to declare all funds borrowed to be due and payable, together with accrued and unpaid interest. Any of our future debt agreements may contain similar restrictions and provisions. We might not be able to repurchase the notes upon a change of control because we may not have sufficient financial resources to repurchase the notes tendered by holders upon a change of control. Our failure to repurchase the notes upon a change of control would cause a default under the indenture governing the notes offered hereby.

An active trading market may not develop for the notes.

The notes will constitute a new issue of securities for which there is no active public trading market. We do not intend to apply for listing of the notes on a securities exchange. The liquidity of the trading market in the notes and the market prices quoted for the notes may be adversely affected by changes in the overall market for this type of securities and by changes in our financial performance or prospects or in the performance or prospects for companies in our industry generally. As a consequence, an active trading market may not develop for the notes, you may not be able to sell the notes, or, even if you can sell the notes, you may not be able to sell them at a price that would be acceptable to you.

S-15

Federal and state laws allow courts, under specific circumstances, to void guarantees and to require you to return payments received from guarantors.

Although you will be direct creditors of the guarantors by virtue of the guarantees, existing or future creditors of any guarantor could avoid or subordinate that guarantor’s guarantee under the fraudulent conveyance laws if they were successful in establishing that:

• the guarantee was incurred with fraudulent intent; or

• the guarantor did not receive fair consideration or reasonably equivalent value for issuing its guarantee and

• was insolvent at the time of the guarantee;

• was rendered insolvent by reason of the guarantee;

• was engaged in a business or transaction for which its assets constituted unreasonably small capital to carry on its business; or

• intended to incur, or believed that it would incur, debt beyond its ability to pay such debt as it matured.

The measures of insolvency for purposes of determining whether a fraudulent conveyance occurred vary depending upon the laws of the relevant jurisdiction and upon the valuation assumptions and methodology applied by the court. Generally, however, a company would be considered insolvent for purposes of the foregoing if:

• the sum of the company’s debts, including contingent, unliquidated and unmatured liabilities, is greater than all of such company’s property at a fair valuation; or

• if the present fair saleable value of the company’s assets is less than the amount that will be required to pay the probable liability on its existing debts as they become absolute and matured.

We cannot assure you as to what standard a court would apply in order to determine whether a guarantor was “insolvent” as of the date its guarantee was issued, and we cannot assure you that, regardless of the method of valuation, a court would not determine that any guarantors were insolvent on that date. The subsidiary guarantees could be subject to the claim that, since the guarantees were incurred for our benefit, and only indirectly for the benefit of the other guarantors, the obligations of the guarantors thereunder were incurred for less than reasonably equivalent value or fair consideration.

Risks relating to our oil and gas business

Natural gas and crude oil prices are volatile, and a substantial or extended decline in prices would hurt our profitability and financial condition.

Our revenues, operating results, cash flows, profitability, future rate of growth and the carrying value of our oil and gas properties depend heavily on prevailing market prices for natural gas and crude oil. Historically, natural gas and crude oil prices have been volatile, and they are likely to continue to be volatile. Wide fluctuations in natural gas and crude oil prices may result from relatively minor changes in the supply of and demand for oil and gas, market demand and other factors that are beyond our control, including:

• domestic and foreign supplies of oil, natural gas and NGLs;

• political and economic conditions in oil or gas producing regions;

S-16

• overall domestic and foreign economic conditions;

• prices and availability of and demand for, alternative fuels;

• the availability of transportation facilities;

• weather conditions; and

• domestic and foreign governmental regulation.

Some of our projections and estimates are based on assumptions as to the future prices of natural gas and crude oil. These price assumptions are used for planning purposes. We expect our assumptions will change over time and that actual prices in the future will likely differ from our estimates. Any substantial or extended decline in the actual prices of natural gas or crude oil would have a material adverse effect on our financial position and results of operations (including reduced cash flows and borrowing capacity and possible asset impairment), the quantities of natural gas and crude oil reserves that we can economically produce, the quantity of estimated proved reserves that may be attributed to our properties and our ability to fund our capital program.

The borrowing base under our Revolver has been reduced and may be further reduced in the future if commodity prices decline.

The borrowing base under our Revolver is currently $420 million. Under the terms of our Revolver, the issuance of the notes will automatically result in a reduction of the borrowing base under our Revolver by $21 million. In addition, the borrowing base under our Revolver will be further reduced by an amount equal to 30% of the aggregate principal amount of our 2012 Convertible Notes that remain outstanding following the Tender Offer.

In addition, our borrowing base is re-determined twice a year. If oil and natural gas commodity prices deteriorate, we anticipate that the borrowing base under our Revolver may be further reduced. As a result, we may be unable to obtain adequate funding under our Revolver. If funding is not available when needed, or is available only on unfavorable terms, it might adversely affect our development plan as currently anticipated and our ability to make new acquisitions, each of which could have a material adverse effect on our production, revenues and results of operations.

Our future performance depends on our ability to find or acquire additional oil and gas reserves that are economically recoverable.

Unless we successfully replace the reserves that we produce, our reserves will decline, eventually resulting in a decrease in oil and gas production and lower revenues and cash flows from operations. We have historically succeeded in substantially replacing reserves primarily through exploration and development and, to a lesser extent, acquisitions. We have conducted such activities on our existing oil and gas properties as well as on newly acquired properties. We may not be able to continue to replace reserves from such activities at acceptable costs. The currently depressed oil and gas prices may further limit the types of reserves that can be developed at acceptable costs. Lower prices also decrease our cash flows and may cause us to reduce capital expenditures. The business of exploring for, developing or acquiring reserves is capital intensive. We may not be able to make the necessary capital investments to maintain or expand our oil and gas reserves if cash flows from operations are reduced and external sources of capital remain limited or unavailable due to the deterioration of the global economy, including financial and credit markets. In addition, exploration and development activities involve numerous risks that may result in dry holes, the failure to produce oil and gas in commercial quantities and the inability to fully produce discovered reserves.

S-17

We are continually identifying and evaluating acquisition opportunities. However, competition for producing oil and gas properties is intense and many of our competitors have financial and other resources substantially greater than those available to us. In the event we are successful in completing an acquisition, we cannot ensure that such acquisition will consist of properties that contain economically recoverable reserves or that such acquisition will be profitably integrated into our operations.

We may not be able to fund our planned capital expenditures.

We make, and will continue to make, substantial capital expenditures to find, acquire, develop, exploit and produce oil and natural gas reserves. In 2011, we anticipate making capital expenditures, excluding acquisitions, of approximately $320 million.

If oil and gas prices decrease or we encounter operating difficulties that result in our cash flows from operations being less than expected, we may have to reduce the capital we can spend unless we have borrowing capacity under our Revolver or we can raise additional funds through debt or equity financing.

Future cash flows and the availability of financing will also be subject to a number of variables, such as our success in locating and producing new reserves, the level of production from existing wells and prices of oil and natural gas.

If our revenues were to decrease due to lower oil and natural gas prices, decreased production or other reasons, and if we could not obtain capital through the Revolver, or otherwise on acceptable terms, our ability to execute our development plans, replace our reserves or maintain production levels could be greatly limited.

Exploration and development drilling may not result in commercially productive reserves.

Oil and gas drilling and production activities are subject to numerous risks, including the risk that no commercially productive natural gas or oil reserves will be found. The costs of drilling, completing and operating wells are often uncertain, and drilling operations may be curtailed, delayed or canceled as a result of a variety of factors, many of which are beyond our control. These factors include:

• unexpected drilling conditions;

• pressure or irregularities in formations;

• equipment failures or accidents;

• costs of, or shortages or delays in the availability of, drilling rigs, equipment and materials;

• shortages in experienced labor;

• failure to secure necessary regulatory approvals and permits;

• title problems;

• fires, explosions, blow-outs and surface cratering; and

• adverse weather conditions.

The prevailing prices of oil and gas also affect the cost of and the demand for drilling rigs, production equipment and related services. The availability of drilling rigs can vary significantly from region to region at any particular time. Although land drilling rigs can be moved from one region to another in response to changes in levels of demand, an undersupply of rigs in any region may result in drilling delays and higher drilling costs for the rigs that are available in that region.

The wells we drill may not be productive and we may not recover all or any portion of our investment in such wells. The seismic data and other technologies we use do not allow us to

S-18

know conclusively prior to drilling a well that natural gas or oil is present or may be produced economically. The cost of drilling, completing and operating a well is often uncertain, and cost factors can adversely affect the economics of a project. Drilling activities can result in dry wells or wells that are productive but do not produce sufficient net revenues after operating and other costs to cover initial drilling costs.

Our future drilling activities may not be successful, nor can we be sure that our overall drilling success rate or our drilling success rate within a particular area will not decline. Unsuccessful drilling activities could have a material adverse effect on our business results of operations, cash flows or financial condition. Also, we may not be able to obtain any options or lease rights in potential drilling locations that we identify. Although we have identified numerous potential drilling locations, we may not be able to economically produce oil or natural gas from all of them.

We are exposed to the credit risk of our customers and joint interest partners, and nonpayment or nonperformance by these parties would reduce our cash flows.

We are subject to risk from loss resulting from our customers’ and joint interest partners’ nonperformance or nonpayment. We depend on a limited number of customers for a significant portion of our revenues. In 2010, 59% of our total consolidated product revenues resulted from four of our customers. Any nonpayment or nonperformance by our customers would reduce our cash flows.

Our business involves many operating risks that may result in substantial losses for which insurance may be unavailable or inadequate.

Our operations are subject to all of the risks and hazards typically associated with the exploitation, development and exploration for and the production and transportation of oil and natural gas. These operating risks include:

• fires, explosions, blowouts, cratering and casing collapses;

• formations with abnormal pressures;

• pipeline ruptures or spills;

• uncontrollable flows of oil, natural gas or well fluids;

• environmental hazards such as natural gas leaks, oil spills and releases of hazardous materials; and

• natural disasters.

Any of these risks could result in substantial losses resulting from injury or loss of life, damage to or destruction of property, natural resources and equipment, pollution and other environmental damages, clean-up costs, regulatory investigations and enforcement proceedings and penalties and suspension of operations. In addition, under certain circumstances, we may be liable for environmental damage and costs to remediate contamination caused by previous owners or operators of properties that we own, lease or operate. As a result, we may incur substantial liabilities to third parties or governmental entities, which could reduce or eliminate funds available for exploration, development or acquisitions or cause us to incur losses.

In accordance with industry practice, we maintain insurance against some, but not all, of the risks described above. We cannot assure you that our insurance will be adequate to cover losses or liabilities. Also, we cannot predict the continued availability of insurance at premium levels that justify its purchase. No assurance can be given that we will be able to maintain insurance in the

S-19

future at rates we consider reasonable. The occurrence of a significant event, not fully insured or indemnified against, could have a material adverse effect on our business, results of operations or financial condition.

Our business depends on transportation facilities owned by others.

We deliver substantially all of our oil and natural gas production through pipelines that we do not own. The marketability of our production depends upon the availability, proximity and capacity of these pipelines as well as gathering systems and processing facilities. The unavailability or lack of available capacity on these systems and facilities could result in the shut-in of producing wells or the delay or discontinuance of development plans for properties. Federal, state and local regulation of oil and natural gas production and transportation, tax and energy policies, changes in supply and demand, pipeline pressures, damage to or destruction of pipelines and general economic conditions could adversely affect our ability to produce, gather and market our oil and natural gas.

Estimates of oil and natural gas reserves are not precise.

This prospectus supplement contains, and certain documents incorporated herein by reference contain, estimates of our proved oil and gas reserves and the estimated future net cash flows from such reserves. These estimates are based upon various assumptions, including assumptions required by the SEC relating to oil and natural gas prices, drilling and operating expenses, capital expenditures, taxes and availability of funds. The process of estimating oil and natural gas reserves is complex. This process requires significant decisions and assumptions in the evaluation of available geological, geophysical, engineering and economic data for each reservoir. These estimates are dependent on many variables and, therefore, changes often occur as these variables evolve and commodity prices fluctuate. Any material inaccuracies in these reserve estimates or underlying assumptions could materially affect the estimated quantities and present value of our reserves.

Actual future production, oil and gas prices, revenues, taxes, development expenditures, operating expenses and quantities of recoverable oil and gas reserves will most likely vary from those estimated. Any significant variance could materially affect the estimated quantities and present value of reserves disclosed by us. In addition, we may adjust estimates of proved reserves to reflect production history, results of exploration and development, prevailing oil and gas prices and other factors, many of which are beyond our control.

At December 31, 2010, approximately 47% of our estimated proved reserves were proved undeveloped. Estimation of proved undeveloped reserves and proved developed non-producing reserves is based on volumetric calculations and adjacent reserve performance data. Recovery of proved undeveloped reserves requires significant capital expenditures and successful drilling operations. Production revenues from proved developed non-producing reserves will not be realized until some time in the future. The reserve data assumes that we will make significant capital expenditures to develop our reserves. Although we have prepared estimates of our reserves and the costs associated with these reserves in accordance with industry standards, these estimated costs may not be accurate, development may not occur as scheduled and actual results may not occur as estimated.

You should not assume that the present value of estimated future net cash flows (standardized measure) referred to herein is the current fair value of our estimated oil and gas reserves. In accordance with SEC requirements, we base the estimated discounted future net cash flows from our proved reserves on prices and costs on the date of the estimate. Actual current and future

S-20

prices and costs may be materially higher or lower than the prices and costs as of the date of the estimate. As a result, net present value estimates using actual prices and costs may be significantly less than the SEC estimate that is provided herein. In addition, the 10% discount factor, which is required by the SEC to be used in calculating discounted future net cash flows for reporting purposes, is not necessarily the most accurate discount factor for us.

We may record impairment losses on our oil and gas properties.

Quantities of proved reserves are estimated based on economic conditions in existence in the period of assessment. Lower oil and gas prices may have the impact of shortening the economic lives on certain fields because it becomes uneconomic to produce all recoverable reserves on such fields, thus reducing proved property reserve estimates. If such revisions in the estimated quantities of proved reserves occur, it will have the effect of increasing the rates of depreciation, depletion and amortization (“DD&A”) on the affected properties, which would decrease earnings or result in losses through higher DD&A expense. The revisions may also be sufficient enough to cause impairment losses on certain properties that would result in a further non-cash charge to reported earnings.

GAAP requires that the carrying value of oil and gas properties be reviewed on a periodic basis for possible impairment. An impairment charge is recognized when the carrying value of oil and gas properties is greater than the undiscounted future net cash flows attributable to the property. In addition to revisions to reserves and the impact of lower commodity prices, impairments may occur due to increases in estimated operating and development costs. During the past several years, we have been required to impair certain of our oil and gas properties and related assets. If natural gas, crude oil and NGL prices decline or we drill uneconomic wells, it is reasonably possible that we will have to record a significant impairment in the future. While an impairment charge reflects our ability to recover the carrying value of our investments, it does not impact our cash flows from operating activities.

We have limited control over the activities on properties we do not operate.

In 2010, other companies operated approximately 27% of our net production. Our success in properties operated by others will depend upon a number of factors outside of our control, including timing and amount of capital expenditures, the operator’s expertise and financial resources, approval of other participants in drilling wells, selection of technology and maintenance of safety and environmental standards. We have limited ability to influence or control the operation or future development of these non-operated properties or the amount of capital expenditures that we are required to fund for their operation. Our dependence on the operator and other working interest owners for these projects and our limited ability to influence or control the operation and future development of these properties could have a material adverse effect on the realization of our targeted returns or lead to unexpected future costs.

Certain working interest owners in our properties have the right to control the timing of drilling activities on our properties under certain circumstances.

Under certain circumstances, certain of the other working interest owners in our properties have the right to limit the amount of drilling activities that can take place on our properties at any given time. If these working interest owners chose to exercise this right, we could be required to scale back anticipated drilling activities on the affected properties. In such an event, production from the affected properties would be deferred, thereby decreasing production from the properties in the short-term.

S-21

Our producing property acquisitions carry significant risks.

Acquisition of producing oil and gas properties is a key element of maintaining and growing reserves and production. Competition for these assets has been and will continue to be intense. In the event we do complete an acquisition, its success will depend on a number of factors, many of which are beyond our control. These factors include the purchase price, future oil and gas prices, the ability to reasonably estimate or assess the recoverable volumes of reserves, rates of future production and future net revenues attainable from reserves, future operating and capital costs, results of future exploration, exploitation and development activities on the acquired properties and future abandonment and possible future environmental or other liabilities. There are numerous uncertainties inherent in estimating quantities of proved oil and gas reserves, actual future production rates and associated costs and potential liabilities with respect to prospective acquisition targets. Actual results may vary substantially from those assumed in the estimates. A customary review of subject properties will not necessarily reveal all existing or potential problems.

Additionally, significant acquisitions can change the nature of our operations and business depending upon the character of the acquired properties if they have substantially different operating and geological characteristics or are in different geographic locations than our existing properties. To the extent that acquired properties are substantially different than our existing properties, our ability to efficiently realize the expected economic benefits of such transactions may be limited.

Integrating acquired businesses and properties involves a number of special risks. These risks include the possibility that management may be distracted from regular business concerns by the need to integrate operations and systems and that unforeseen difficulties can arise in integrating operations and systems and in retaining and assimilating employees. Any of these or other similar risks could lead to potential adverse short-term or long-term effects on our operating results, and may cause us to not be able to realize any or all of the anticipated benefits of the acquisitions.

Derivative transactions may limit our potential gains and involve other risks.

In order to manage our exposure to price risks in the sale of our oil and natural gas, we periodically enter into oil and gas price hedging arrangements with respect to a portion of our expected production. Our hedges are limited in duration, usually for periods of two years or less. While intended to reduce the effects of volatile oil and natural gas prices, such transactions may limit our potential gains if oil or natural gas prices were to rise over the price established by the hedging arrangements. In trying to maintain an appropriate balance, we may end up hedging too much or too little, depending upon how oil or natural gas prices fluctuate in the future.

In addition, derivative transactions may expose us to the risk of financial loss in certain circumstances, including instances in which:

• our production is less than expected;

• there is a widening of price basis differentials between delivery points for our production and the delivery point assumed in the hedge arrangement;

• the counterparties to our futures contracts fail to perform under the contracts; or

• a sudden, unexpected event materially impacts oil or natural gas prices.

S-22

In addition, derivative instruments involve basis risk. Basis risk in a derivative contract occurs when the index upon which the contract is based is more or less variable than the index upon which the hedged asset is based, thereby making the hedge less effective. For example, a NYMEX index used for hedging certain volumes of production may have more or less variability than the regional price index used for the sale of that production.

We are subject to complex laws and regulations that can adversely affect the cost, manner or feasibility of doing business.

Exploration, development, production and sale of oil and gas are subject to extensive federal, state and local laws and regulations, including complex environmental laws. Future laws or regulations, any adverse changes in the interpretation of existing laws and regulations, inability to obtain necessary regulatory approvals or a failure to comply with existing legal requirements may harm our business, results of operations or financial condition. We may be required to make large expenditures to comply with environmental and other governmental regulations. Failure to comply with these laws and regulations may result in the suspension or termination of operations and subject us to administrative, civil and criminal penalties. Matters subject to regulation include drilling bonds, spacing of wells, unitization and pooling of properties and taxation. Our operations are also regulated extensively under environmental laws, including those relating to discharges of oil, gas or other regulated materials into the air, soil or water, and the management of regulated wastes. Our operations create the risk of environmental liabilities to the government or third parties, including for damages to natural resources, personal property or human health, fines and penalties for violations of applicable laws or permits, and the costs of investigation and remediation of releases of regulated materials. Some of these liabilities, particularly for releases of regulated materials into the environment and for damages to natural resources, personal property or human health, may be both strict and under certain circumstances, joint and several in nature. Moreover, laws and regulations protecting the environment have become more stringent in recent years and that trend appears likely to continue. In addition, pollution and similar environmental risks generally are not fully insurable. These liabilities and costs could have a material adverse effect on our business, financial condition or results of operations.

The recent adoption of derivatives legislation by the U.S. Congress could have an adverse effect on our ability to use derivative instruments to reduce the effect of commodity price, interest rate and other risks associated with our business.

The U.S. Congress adopted comprehensive financial reform legislation that establishes federal oversight and regulation of the over-the-counter derivatives market and entities, such as us, that participate in that market. The new legislation, known as the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Act”) was signed into law on July 21, 2010 and requires the Commodities Futures Trading Commission (the “CFTC”) and the SEC to promulgate rules and regulations implementing the new legislation within 360 days from the date of enactment. In its rulemaking under the Act, the CFTC has proposed regulations to set position limits for certain futures and option contracts in the major energy markets and for swaps that are their economic equivalents. Certain bona fide hedging transactions or positions would be exempt from these position limits. It is not possible at this time to predict when the CFTC will finalize these regulations. The financial reform legislation may also require us to comply with margin requirements and with certain clearing and trade-execution requirements in connection with our derivative activities, although the application of those provisions to us is uncertain at this time. The financial reform legislation may also require the counterparties to our derivative instruments to spin off some of their derivatives activities to a separate entity, which may not be as

S-23

creditworthy as the current counterparty. The new legislation and any new regulations could significantly increase the cost of derivative contracts (including through requirements to post collateral which could adversely affect our available liquidity), materially alter the terms of derivative contracts, reduce the availability of derivatives to protect against risks that we encounter, reduce our ability to monetize or restructure our existing derivative contracts and increase our exposure to less creditworthy counterparties. If we reduce our use of derivatives as a result of the legislation and regulations, our results of operations may become more volatile and our cash flows may be less predictable, which could adversely affect our ability to plan for and fund capital expenditures. Finally, the legislation was intended, in part, to reduce the volatility of oil and natural gas prices, which some legislators attributed to speculative trading in derivatives and commodity instruments related to oil and natural gas. Our revenues could therefore be adversely affected if a consequence of the legislation and regulations is to lower commodity prices. Any of these consequences could have a material adverse effect on us, our financial condition and our results of operations.

Risks relating to taxes

Certain U.S. federal income tax deductions currently available with respect to oil and gas exploration and development may be eliminated as a result of future legislation.

Legislation has been proposed in the U.S. Congress that would, if enacted into law, make significant changes to U.S. federal income tax laws, including the elimination of certain key U.S. federal income tax preferences currently available to oil and natural gas exploration and production companies. These changes include, but are not limited to, (i) the repeal of the percentage depletion allowance for oil and natural gas properties, (ii) the elimination of current deductions for intangible drilling and development costs, (iii) the elimination of the deduction for certain domestic production activities and (iv) an extension of the amortization period for certain geological and geophysical expenditures. It is unclear whether these or similar changes will be enacted and, if enacted, how soon any such changes could become effective. The passage of this legislation or any other similar changes in U.S. federal income tax laws could eliminate or postpone certain tax deductions that are currently available with respect to oil and natural gas exploration and development, and any such change could have a material adverse effect on us.

Use of proceeds

We estimate the net proceeds to us from this offering will be approximately $293.0 million, after deducting estimated fees and expenses payable by us (including underwriting discounts and commissions). We intend to use a portion of the net proceeds from this offering to fund the Tender Offer described under “Summary—Recent developments—Tender offer for convertible notes.” Any remaining net proceeds will be used to provide additional working capital for general corporate purposes.

Certain of the underwriters or their affiliates are holders of our 2012 Convertible Notes and, accordingly, they will receive a portion of the net proceeds of this offering in connection with the Tender Offer. See “Underwriting.”

(1) Assumes that $218.5 million aggregate principal amount of our 2012 Convertible Notes outstanding had been validly tendered and not validly withdrawn as of December 31, 2010 pursuant to the Tender Offer (which represents 95% of the aggregate outstanding principal amount of our 2012 Convertible Notes). As of the close of business on April 4, 2011, approximately $225 million aggregate principal amount of our 2012 Convertible Notes have been validly tendered and not validly withdrawn pursuant to the Tender Offer. See “Summary—Recent developments—Tender offer for convertible notes.”

(2) After giving effect to the issuance and sale of the notes and the application of the net proceeds therefrom, as of December 31, 2010, we would have had availability of up to $299.3 million under our Revolver, net of $0.7 million in letters of credit outstanding.

Description of other indebtedness

Our revolver

Our Revolver provides for a $300 million revolving credit facility and matures in November 2012. We have the option to increase the aggregate commitments under our Revolver by up to an additional $225 million upon the receipt of additional commitments from one or more lenders. Our Revolver is limited by a borrowing base calculation, and the availability under our Revolver may not exceed the lesser of the aggregate commitments or the borrowing base. As of December 31, 2010, the borrowing base, which is redetermined semi-annually, was $420 million. Our Revolver is available to us for general purposes including working capital, capital expenditures and acquisitions and includes a $20 million sublimit for the issuance of letters of credit.

Borrowings under our Revolver bear interest, at our option, at either (i) a rate derived from the London Interbank Offered Rate, as adjusted for statutory reserve requirements for Eurocurrency liabilities (the “Adjusted LIBOR”), plus an applicable margin ranging from 2.000% to 3.000% or (ii) the greater of (a) the prime rate, (b) federal funds effective rate plus 0.5% and (c) the one-month Adjusted LIBOR plus 1.0%, in each case, plus an applicable margin (ranging from 1.000% to 2.000%). In each case, the applicable margin is determined based on the ratio of our outstanding borrowings to the available Revolver capacity.

Our Revolver is guaranteed by Penn Virginia Corporation and all of our material subsidiaries (the “Guarantor Subsidiaries”). The obligations under our Revolver are secured by a first priority lien on substantially all of our proved oil and gas reserves and a pledge of the equity interests in the Guarantor Subsidiaries.

As of December 31, 2010, there were no amounts outstanding under our Revolver, and we had available borrowing capacity of $299.3 million, net of outstanding letters of credit of $0.7 million. In addition, there were no borrowings outstanding during 2010.

The financial covenants under our Revolver require us to abide by specified financial covenants, as follows:

• Total debt to EBITDAX, each as defined in our Revolver, for any four consecutive quarters may not exceed 4.0 to 1.0, reducing to 3.5 to 1.0 for periods ending on or after September 30, 2011. EBITDAX, which is a non-GAAP measure, generally means net income plus interest expense, taxes, depreciation, depletion and amortization expenses, exploration expenses, impairments, other non-cash charges or losses and the amount of cash distributions received from PVG and PVR.

• The current ratio, as of the last day of any quarter, may not be less than 1.0 to 1.0. The current ratio is generally defined as current assets to current liabilities. Current assets and current liabilities attributable to derivative instruments are also excluded. In addition, current assets include the amount of any unused commitment under our Revolver.

As of December 31, 2010, we were in compliance with the applicable covenants of our Revolver.

In the event that we would be in default of our covenants under our Revolver, we could appeal to the banks for a waiver of the covenant. Should the banks deny our appeal to waive the covenant requirement, the outstanding borrowings under our Revolver would become payable on demand and would be reclassified as a component of current liabilities on our consolidated balance sheet. In addition, our Revolver imposes limitations on dividends and distributions, as well as limits our

S-27

ability to incur indebtedness, grant liens, make certain loans, acquisitions and investments, make any material change to the nature of our business or enter into a merger or sale of our assets, including the sale or transfer of interests in our subsidiaries.

Our 2016 senior notes

As of December 31, 2010, we had $300.0 million (excluding the unamortized original issue discount of $7.5 million) of our 2016 Senior Notes outstanding. Our 2016 Senior Notes bear interest at an annual rate of 10.375% and mature in June 2016. Interest is payable semi-annually in arrears on June 15 and December 15 of each year. Our 2016 Senior Notes were sold at 97% of par, equating to an effective yield to maturity of approximately 11%. Beginning in June 2013, we may redeem all or part of our 2016 Senior Notes at a redemption price beginning at 105.188% of the principal amount and reducing to 100.0% in June 2015 and thereafter. Our 2016 Senior Notes are senior to our existing and future subordinated indebtedness and are effectively subordinated to all of our secured indebtedness, including our Revolver, to the extent of the collateral securing such indebtedness. The obligations under our 2016 Senior Notes are fully and unconditionally guaranteed by the Guarantor Subsidiaries. The covenants contained in the indenture governing our 2016 Senior Notes are substantially similar to the covenants that will be contained in the indenture governing the notes.

Our 2012 convertible notes, note hedges and warrants

As of December 31, 2010, we had $230.0 million (excluding the unamortized original issue discount of $16.0 million) of our 2012 Convertible Notes outstanding. Our 2012 Convertible Notes bear interest at a rate of 4.50% per year payable semiannually in arrears on May 15 and November 15 of each year. On March 8, 2011, we commenced the Tender Offer. See “Summary—Recent developments—Tender offer for convertible notes.”

Our 2012 Convertible Notes are convertible into cash up to the principal amount thereof and shares of our common stock, if any, in respect of the excess conversion value, based on an initial conversion rate of 17.3160 shares of common stock per $1,000 principal amount of our 2012 Convertible Notes (which is equal to an initial conversion price of approximately $57.75 per share of common stock), subject to adjustment, and, if not converted or repurchased earlier, will mature on November 15, 2012. Holders of our 2012 Convertible Notes may convert their 2012 Convertible Notes at their option prior to the close of business on the business day immediately preceding September 15, 2012 only under the following circumstances: (i) during any fiscal quarter if the last reported sale price per share of common stock for at least 20 trading days (whether or not consecutive) in the 30 consecutive trading days ending on the last trading day of the immediately preceding fiscal quarter is greater than or equal to 130% of the then applicable conversion price on each such trading day; (ii) during the five business day period after any ten consecutive trading day period in which the trading price per $1,000 principal amount of our 2012 Convertible Notes for each day of such period was less than 98% of the product of the last reported sale price per share of common stock and the applicable conversion rate on each such day; or (iii) upon the occurrence of certain corporate events set forth in the indenture governing our 2012 Convertible Notes. On and after September 15, 2012 until the close of business on the third business day immediately preceding November 15, 2012, holders of our 2012 Convertible Notes may convert their 2012 Convertible Notes at any time, regardless of the foregoing circumstances.

The holders of our 2012 Convertible Notes who convert their 2012 Convertible Notes in connection with a make-whole fundamental change, as defined in the indenture governing our 2012

S-28

Convertible Notes, may be entitled to an increase in the conversion rate as specified in the indenture governing our 2012 Convertible Notes. Additionally, in the event of a fundamental change, as defined in the indenture governing our 2012 Convertible Notes, the holders of our 2012 Convertible Notes may require us to purchase all or a portion of their 2012 Convertible Notes at a purchase price equal to 100% of the principal amount of our 2012 Convertible Notes, plus accrued and unpaid interest, if any.

Our 2012 Convertible Notes are our unsecured senior subordinated obligations, ranking junior in right of payment to any of our senior indebtedness and to any of our secured indebtedness to the extent of the value of the assets securing such indebtedness and equal in right of payment to any of our future unsecured senior subordinated indebtedness. Our 2012 Convertible Notes will rank senior in right of payment to any of our future junior subordinated indebtedness and will structurally rank junior to all existing and future indebtedness of our subsidiaries.

In connection with the sale of our 2012 Convertible Notes, we entered into convertible note hedge transactions (the “Note Hedges”) with respect to shares of our common stock with affiliates of certain of the underwriters of our 2012 Convertible Notes (the “Option Counterparties”). The Note Hedges cover, subject to anti-dilution adjustments, the net shares of our common stock that would be deliverable to converting noteholders in the event of a conversion of our 2012 Convertible Notes. In December 2007, we paid an aggregate amount of $18.6 million of the net proceeds from the sale of our 2012 Convertible Notes for the cost of the Note Hedges (after such cost was offset by the proceeds of the Warrants described below).

We also entered into separate warrant transactions (the “Warrants”) whereby we sold to the Option Counterparties warrants to acquire, subject to anti-dilution adjustments, approximately 3,982,680 shares of our common stock at an exercise price of $74.25 per share. In December 2007, we received proceeds of $18.2 million resulting from this sale. Upon exercise of the Warrants, we will deliver shares of our common stock equal to the difference between the then market price and the strike price of the Warrants.

If the market value per share of our common stock at the time of conversion of our 2012 Convertible Notes is above the strike price of the Note Hedges, the Note Hedges entitle us to receive from the Option Counterparties net shares of our common stock (and cash for any fractional share cash amount) based on the excess of the then current market price of our common stock over the strike price of the Note Hedges. Additionally, if the market price of our common stock at the time of exercise of the Warrants exceeds the strike price of the Warrants, we will owe the Option Counterparties net shares of our common stock (and cash for any fractional share cash amount), not offset by the Note Hedges, in an amount based on the excess of the then current market price of our common stock over the strike price of the Warrants.

In connection with the Tender Offer, we may enter into agreements with one or more of the Option Counterparties pursuant to which we would terminate or otherwise unwind in part or in full certain of the Note Hedges and the Warrants.

S-29

Description of notes

We will issue the Notes under an indenture, as supplemented by a supplemental indenture (collectively the “Indenture”), among us, the Subsidiary Guarantors and Wells Fargo Bank, National Association, as trustee (the “Trustee”). The terms of the Notes include those expressly set forth in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). The Indenture is unlimited in aggregate principal amount, although the issuance of Notes in this offering will be limited to $300.0 million. We may issue an unlimited principal amount of additional notes having identical terms and conditions as the Notes (the “Additional Notes”). We will only be permitted to issue such Additional Notes in compliance with the covenant described under the subheading “—Certain covenants—Limitation on Indebtedness and Preferred Stock.” Any Additional Notes will be part of the same issue as the Notes that we are currently offering and will vote on all matters with the holders of the Notes. Unless the context otherwise requires, for all purposes of the Indenture and this “Description of notes,” references to the Notes include any Additional Notes actually issued.

This description of notes is intended to be a useful overview of the material provisions of the Notes and the Indenture. Since this description of notes is only a summary, you should refer to the Indenture for a complete description of the obligations of the Company and your rights.

You will find the definitions of capitalized terms used in this description of notes under the heading “Certain definitions.” For purposes of this description, references to “the Company,” “we,” “our” and “us” refer only to Penn Virginia Corporation and not to any of its subsidiaries.

• will be initially unconditionally guaranteed on a senior basis by Penn Virginia Holding Corp., Penn Virginia Oil & Gas Corporation, Penn Virginia Oil & Gas GP LLC, Penn Virginia Oil & Gas LP LLC, Penn Virginia Oil & Gas, L.P., Penn Virginia MC Corporation, Penn Virginia MC Energy L.L.C. and Penn Virginia MC Operating Company L.L.C., representing each Restricted Subsidiary of the Company that currently is a borrower (in the case of Penn Virginia Holding Corp.) or guarantees (in the case of the other Subsidiary Guarantors) the Senior Secured Credit Agreement, see “—Subsidiary guarantees”;

S-30

• effectively rank junior to any existing or future secured Indebtedness of the Company, including amounts that may be borrowed under the Senior Secured Credit Agreement, to the extent of the value of the collateral securing such Indebtedness; and

• rank structurally junior to the indebtedness and other obligations of our non-guarantor subsidiaries, including each of our Unrestricted Subsidiaries.

Interest. Interest on the Notes will compound semi-annually and will:

• accrue at the rate of 7.25% per annum;

• accrue from the Issue Date or, if interest has already been paid, from the most recent interest payment date;

• be payable in cash semi-annually in arrears on April 15 and October 15, commencing on October 15, 2011;

• be payable to the holders of record on the April 1 and October 1 immediately preceding the related interest payment dates; and

• be computed on the basis of a 360-day year comprised of twelve 30-day months.

If an interest payment date falls on a day that is not a Business Day, the interest payment to be made on such interest payment date will be made on the next succeeding Business Day with the same force and effect as if made on such interest payment date, and no additional interest will accrue as a result of such delayed payment. The Company will pay interest on overdue principal of the Notes at the above rate, and overdue installments of interest at such rate, to the extent lawful.

Payments on the Notes; paying agent and registrar

We will pay principal of, premium, if any, and interest on the Notes at the office or agency designated by the Company in the City and State of New York, except that we may, at our option, pay interest on the Notes by check mailed to holders of the Notes at their registered address as it appears in the registrar’s books. We have initially designated the corporate trust office of the Trustee in New York, New York to act as our paying agent and registrar. We may, however, change the paying agent or registrar without prior notice to the holders of the Notes, and the Company or any of its Restricted Subsidiaries may act as paying agent or registrar.

We will pay principal of, premium, if any, and interest on, Notes in global form registered in the name of or held by The Depository Trust Company or its nominee in immediately available funds to The Depository Trust Company or its nominee, as the case may be, as the registered holder of such global Note.

Transfer and exchange

A holder may transfer or exchange Notes in accordance with the Indenture. The registrar and the Trustee may require a holder, among other things, to furnish appropriate endorsements and transfer documents in connection with a transfer of Notes. No service charge will be imposed by the Company, the Trustee or the registrar for any registration of transfer or exchange of Notes, but the Company may require a holder to pay a sum sufficient to cover any transfer tax or other governmental taxes and fees required by law or permitted by the Indenture. The Company is not

S-31

required to transfer or exchange any Note selected for redemption. Also, the Company is not required to transfer or exchange any Note for a period of 15 days before a selection of Notes to be redeemed.

The registered holder of a Note will be treated as the owner of it for all purposes.

Optional redemption

On and after April 15, 2015, we may redeem all or, from time to time, a part of the Notes upon not less than 30 nor more than 60 days’ notice, at the following redemption prices (expressed as a percentage of principal amount of the Notes), plus accrued and unpaid interest on the Notes, if any, to the applicable redemption date (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date), if redeemed during the twelve-month period beginning on April 15 of the years indicated below:

Year	Percentage
2015		103.625%
2016		101.813%
2017 and thereafter		100.000%

Prior to April 15, 2014, we may, at our option, on any one or more occasions redeem up to 35% of the aggregate principal amount of the Notes (including Additional Notes) issued under the Indenture with the Net Cash Proceeds of one or more Equity Offerings at a redemption price of 107.250% of the principal amount thereof, plus accrued and unpaid interest, if any, to the redemption date (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date); provided that

(1) at least 65% of the original principal amount of the Notes issued on the Issue Date remains outstanding after each such redemption; and

(2) the redemption occurs within 90 days after the closing of the related Equity Offering.

In addition, the Notes may be redeemed, in whole or in part, at any time prior to April 15, 2015 at the option of the Company upon not less than 30 nor more than 60 days’ prior notice mailed by first-class mail to each holder of Notes at its registered address, at a redemption price equal to 100% of the principal amount of the Notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest to, the applicable redemption date (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date). “Applicable Premium” means, with respect to any Note on any applicable redemption date, the greater of:

(1) 1.0% of the principal amount of such Note; and

(2) the excess, if any, of:

(a) the present value at such redemption date of (i) the redemption price of such Note at April 15, 2015 (such redemption price being set forth in the table appearing above under the caption “Optional redemption”) plus (ii) all required interest payments (excluding accrued and unpaid interest to such redemption date) due on such Note through April 15, 2015 computed using a discount rate equal to the Treasury Rate as of such redemption date plus 50 basis points; over

(b) the principal amount of such Note.

S-32

“Treasury Rate” means, as of any redemption date, the yield to maturity at the time of computation of United States Treasury securities with a constant maturity (as compiled and published in the most recent Federal Reserve Statistical Release H.15 (519) which has become publicly available at least two Business Days prior to the redemption date (or, if such Statistical Release is no longer published, any publicly available source or similar market data)) most nearly equal to the period from the redemption date to April 15, 2015; provided, however, that if the period from the redemption date to April 15, 2015 is not equal to the constant maturity of a United States Treasury security for which a weekly average yield is given, the Treasury Rate shall be obtained by linear interpolation (calculated to the nearest one-twelfth of a year) from the weekly average yields of United States Treasury securities for which such yields are given, except that if the period from the redemption date to April 15, 2015 is less than one year, the weekly average yield on actually traded United States Treasury securities adjusted to a constant maturity of one year shall be used.

The Company will calculate the Treasury Rate prior to such redemption date and file with the Trustee an Officers’ Certificate setting forth the Applicable Premium and the Treasury Rate and showing the calculation of each in reasonable detail.

Selection and notice

If the Company is redeeming less than all of the outstanding Notes, the Trustee will select the Notes for redemption in compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed or, if the Notes are not listed, then on a pro rata basis (or in case of global notes, on as nearly a pro rata basis as is practicable, subject to the procedures of The Depository Trust Company), by lot or by such other method as the Trustee in its sole discretion will deem to be fair and appropriate, although no Note of $2,000 in original principal amount or less will be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption relating to such Note will state the portion of the principal amount thereof to be redeemed. A new Note in principal amount equal to the unredeemed portion thereof will be issued in the name of the holder thereof upon cancellation of the partially redeemed Note. On and after the redemption date, interest will cease to accrue on Notes or the portion of them called for redemption unless we default in the payment thereof.

Mandatory redemption; Offers to purchase; Open market purchases

We are not required to make mandatory redemption payments or sinking fund payments with respect to the Notes. However, under certain circumstances, we may be required to offer to purchase Notes as described under the captions “—Change of control” and “—Certain covenants—Limitation on sales of assets and Subsidiary stock.”

We may acquire Notes by means other than a redemption, whether by tender offer, open market purchases, negotiated transactions or otherwise, in accordance with applicable securities laws, so long as such acquisition does not otherwise violate the terms of the Indenture. However, other existing or future agreements of the Company may limit the ability of the Company or its Subsidiaries to purchase Notes prior to maturity.

Ranking

The Notes will be general unsecured obligations of the Company that rank senior in right of payment to all existing and future Indebtedness that is expressly subordinated in right of payment

S-33

to the Notes, including any of the Convertible Notes that remain outstanding after consummation of the Transactions. The Notes will rank equally in right of payment with all existing and future liabilities of the Company that are not so subordinated, including our Existing Senior Notes and the Senior Secured Credit Agreement, and will be effectively subordinated to all of the secured Indebtedness, including Indebtedness Incurred under the Senior Secured Credit Agreement, to the extent of the value of the collateral securing such Indebtedness, and liabilities of any of our Subsidiaries that do not guarantee the Notes (including each of our Unrestricted Subsidiaries). In the event of bankruptcy, liquidation, reorganization or other winding up of the Company or its Subsidiary Guarantors or upon a default in payment with respect to, or the acceleration of, any Indebtedness under the Senior Secured Credit Agreement or other secured Indebtedness, the assets of the Company and its Subsidiary Guarantors that secure secured Indebtedness will be available to pay obligations on the Notes and the Subsidiary Guarantees only after all Indebtedness under the Senior Secured Credit Agreement and other secured Indebtedness has been repaid in full from such assets. In addition, in the event of bankruptcy, liquidation, reorganization or other winding up of an Unrestricted Subsidiary, the assets of such Unrestricted Subsidiary will be available to pay obligations on the Notes only after all obligations of such Unrestricted Subsidiary have been repaid in full from such assets. In addition, in the event of bankruptcy, liquidation, reorganization or other winding up of an Unrestricted Subsidiary, the assets of such Unrestricted Subsidiary will be available to pay obligations on the Notes only after all obligations of such Unrestricted Subsidiary have been repaid in full from such assets. We advise you that there may not be sufficient assets remaining to pay amounts due on any or all the Notes and the Subsidiary Guarantees then outstanding.

As of December 31, 2010, on an as adjusted basis after giving effect to this offering and the application of net proceeds from this offering as more fully described in “Use of proceeds” and assuming $218.5 million of the Convertible Notes had been validly tendered and not withdrawn pursuant to the Tender Offer (which represents 95% of the aggregate outstanding principal amount of the 2012 Convertible Notes):

• we and our Subsidiary Guarantors would have had $611.5 million of total Indebtedness (excluding $8.3 million of unamortized original issue discount); and

• of the $611.5 million of total Indebtedness, none would have constituted secured Indebtedness under the Senior Secured Credit Agreement and we would have additional availability of $299.3 million (net of $0.7 million of letters of credit) under the Senior Secured Credit Agreement as to which the Notes would have been effectively subordinated to the extent of the assets secured thereby.

As of December 31, 2010, the Company’s Subsidiaries (other than the Subsidiary Guarantors) would have had de minimis indebtedness and other liabilities, which indebtedness would rank structurally senior to the Notes and the related Subsidiary Guarantees.

Subsidiary guarantees

The Subsidiary Guarantors will, jointly and severally, fully and unconditionally guarantee on a senior unsecured basis our obligations under the Notes and all obligations under the Indenture. The obligations of Subsidiary Guarantors under the Subsidiary Guarantees will rank equally in right of payment with other Indebtedness of such Subsidiary Guarantor, including its guarantee of the Senior Secured Credit Agreement and the Existing Senior Notes, except to the extent such other Indebtedness is expressly subordinate to the obligations arising under the Subsidiary Guarantee.

S-34

As of December 31, 2010, on an as adjusted basis and after giving effect to this offering and the application of net proceeds from this offering, as more fully described under “Use of proceeds,” the Subsidiary Guarantors would have had $611.5 million of Indebtedness, consisting of unsecured guarantees of $611.5 million (excluding $8.3 million of unamortized original issue discount) under the Existing Senior Notes and the Notes.

Although the Indenture will limit the amount of Indebtedness that Restricted Subsidiaries may Incur, such Indebtedness may be substantial and such limitation is subject to a number of significant qualifications. Moreover, the Indenture does not impose any limitation on the Incurrence by such Subsidiaries of liabilities that are not considered Indebtedness under the Indenture. See “—Certain covenants—Limitation on Indebtedness and Preferred Stock.”

The obligations of each Subsidiary Guarantor under its Subsidiary Guarantee will be limited as necessary to prevent that Subsidiary Guarantee from constituting a fraudulent conveyance or fraudulent transfer under applicable law, although no assurance can be given that a court would give the holder the benefit of such provision. See “Risk factors—Risks relating to the offering—Federal and state laws allow courts, under specific circumstances, to void guarantees and to require you to return payments received from guarantors.” If a Subsidiary Guarantee were rendered voidable, it could be subordinated by a court to all other indebtedness (including guarantees and other contingent liabilities) of the applicable Subsidiary Guarantor, and, depending on the amount of such indebtedness, a Subsidiary Guarantor’s liability on its Subsidiary Guarantee could be reduced to zero. If the obligations of a Subsidiary Guarantor under its Subsidiary Guarantee were avoided, holders of Notes would have to look to the assets of any remaining Subsidiary Guarantors for payment. There can be no assurance in that event that such assets would suffice to pay the outstanding principal and interest on the Notes.

In the event a Subsidiary Guarantor is sold or disposed of (whether by merger, consolidation, the sale of its Capital Stock or the sale of all or substantially all of its assets (other than by lease)) and whether or not the Subsidiary Guarantor is the surviving corporation in such transaction to a Person which is not the Company or a Restricted Subsidiary of the Company, such Subsidiary Guarantor will be released from its obligations under its Subsidiary Guarantee if the sale or other disposition does not violate the covenants described under “Certain covenants—Limitation on sales of assets and Subsidiary stock.”

In addition, a Subsidiary Guarantor will be released from its obligations under the Indenture, and its Subsidiary Guarantee, upon the release or discharge of the Guarantee that resulted in the creation of such Subsidiary Guarantee pursuant to the covenant described under “—Future subsidiary guarantors,” except a release or discharge by or as a result of payment under such Guarantee; if the Company designates such Subsidiary as an Unrestricted Subsidiary and such designation complies with the other applicable provisions of the Indenture or in connection with any covenant defeasance, legal defeasance or satisfaction and discharge of the Notes as provided below under the captions “Defeasance” and “Satisfaction and discharge.”

Initially, all of the Company’s Subsidiaries, other than certain Subsidiaries that do not currently guarantee the Senior Secured Credit Agreement, will be Subsidiary Guarantors and Restricted Subsidiaries. In addition, under certain circumstances, the Company may designate additional Subsidiaries as Unrestricted Subsidiaries. None of the Unrestricted Subsidiaries will be subject to the restrictive covenants in the Indenture and none will guarantee the Notes.

S-35

Change of control

If a Change of Control occurs, unless the Company has previously or concurrently exercised its right to redeem all of the Notes as described under “Optional redemption,” each holder will have the right to require the Company to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess of $2,000) of such holder’s Notes at a purchase price in cash equal to 101% of the principal amount of the Notes plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date).

Within 30 days following any Change of Control, unless we have previously or concurrently exercised our right to redeem all of the Notes as described under “Optional redemption,” we will mail a notice (the “Change of Control Offer”) to each holder, with a copy to the Trustee, stating:

(1) that a Change of Control has occurred and that such holder has the right to require us to purchase such holder’s Notes at a purchase price in cash equal to 101% of the principal amount of such Notes plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of holders of record on a record date to receive interest on the relevant interest payment date) (the “Change of Control Payment”);

(2) the repurchase date (which shall be no earlier than 30 days nor later than 60 days from the date such notice is mailed) (the “Change of Control Payment Date”);

(3) that any Note not properly tendered will remain outstanding and continue to accrue interest;

(4) that unless we default in the payment of the Change of Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer will cease to accrue interest on the Change of Control Payment Date;

(5) that holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender such Notes, with the form entitled “Option of Holder to Elect Purchase” on the reverse of such Notes completed, to the paying agent specified in the notice at the address specified in the notice prior to the close of business on the third Business Day preceding the Change of Control Payment Date;

(6) that holders will be entitled to withdraw their tendered Notes and their election to require us to purchase such Notes; provided that the paying agent receives, not later than the close of business on the 30th day following the date of the Change of Control notice, a telegram, telex, facsimile transmission or letter setting forth the name of the holder of the Notes, the principal amount of Notes tendered for purchase, and a statement that such holder is withdrawing its tendered Notes and its election to have such Notes purchased;

(7) that if we are redeeming less than all of the Notes, the holders of the remaining Notes will be issued new Notes and such new Notes will be equal in principal amount to the unpurchased portion of the Notes surrendered. The unpurchased portion of the Notes must be equal to a minimum principal amount of $2,000 and an integral multiple of $1,000 in excess of $2,000; and

(8) the procedures determined by us, consistent with the Indenture, that a holder must follow in order to have its Notes repurchased.

S-36

On the Change of Control Payment Date, the Company will, to the extent lawful:

(1) accept for payment all Notes or portions of Notes (in a minimum principal amount of $2,000 and integral multiples of $1,000 in excess of $2,000) properly tendered pursuant to the Change of Control Offer;

(2) deposit with the paying agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered and not properly withdrawn; and

(3) deliver or cause to be delivered to the Trustee the Notes so accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Company.

The paying agent will promptly mail to each holder of Notes properly tendered and not properly withdrawn the Change of Control Payment for such Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each such new Note will be in a minimum principal amount of $2,000 or an integral multiple of $1,000 in excess of $2,000.

If the Change of Control Payment Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest will be paid to the Person in whose name a Note is registered at the close of business on such record date, and no further interest will be payable to holders who tender pursuant to the Change of Control Offer.

The Change of Control provisions described above will be applicable whether or not any other provisions of the Indenture are applicable. Except as described above with respect to a Change of Control, the Indenture does not contain provisions that permit the holders to require that the Company repurchase or redeem the Notes in the event of a takeover, recapitalization or similar transaction.

We will not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in the Indenture applicable to a Change of Control Offer made by us and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer.

A Change of Control Offer may be made in advance of a Change of Control, and conditioned upon the occurrence of a Change of Control, if a definitive agreement is in place for the Change of Control at the time of making the Change of Control Offer.

We will comply, to the extent applicable, with the requirements of Rule 14e-1 of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Notes as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with provisions of the Indenture, or compliance with the Change of Control provisions of the Indenture would constitute a violation of any such laws or regulations, we will comply with the applicable securities laws and regulations and will not be deemed to have breached our obligations described in the Indenture by virtue of our compliance with such securities laws or regulations.

Our ability to repurchase Notes pursuant to a Change of Control Offer may be limited by a number of factors. The occurrence of certain of the events that constitute a Change of Control would constitute a default under the Senior Secured Credit Agreement. In addition, certain events that

S-37

may constitute a change of control under the Senior Secured Credit Agreement and cause a default under that agreement will not constitute a Change of Control under the Indenture. Future Indebtedness of the Company and its Subsidiaries may also contain prohibitions of certain events that would constitute a Change of Control or require such Indebtedness to be repurchased upon a Change of Control. Moreover, the exercise by the holders of their right to require the Company to repurchase the Notes could cause a default under such Indebtedness, even if the Change of Control itself does not, due to the financial effect of such repurchase on the Company. Finally, the Company’s ability to pay cash to the holders upon a repurchase may be limited by the Company’s then existing financial resources. There can be no assurance that sufficient funds will be available when necessary to make any required repurchases.

Even if sufficient funds were otherwise available, the terms of the Senior Secured Credit Agreement will, and other and/or future Indebtedness may, prohibit the Company’s prepayment or repurchase of Notes before their scheduled maturity. Consequently, if the Company is not able to prepay the Indebtedness under the Senior Secured Credit Agreement and any such other Indebtedness containing similar restrictions or obtain requisite consents, the Company will be unable to fulfill its repurchase obligations if holders of Notes exercise their repurchase rights following a Change of Control, resulting in a default under the Indenture. A default under the Indenture may result in a cross-default under the Senior Secured Credit Agreement.

If holders of not less than 90% in aggregate principal amount of the outstanding Notes validly tender and do not withdraw such Notes in a Change of Control Offer and the Company, or any third party making a Change of Control Offer in lieu of the Company as described above, purchases all of the Notes validly tendered and not withdrawn by such holders, the Company will have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days following such purchase pursuant to the Change of Control Offer described above, to redeem all Notes that remain outstanding following such purchase at a redemption price in cash equal to the applicable Change of Control Payment plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest, if any, to the date of redemption.

The Change of Control provisions described above may deter certain mergers, tender offers and other takeover attempts involving the Company. The Change of Control purchase feature is a result of negotiations between the underwriters and us. As of the Issue Date, we have no present intention to engage in a transaction involving a Change of Control, although it is possible that we could decide to do so in the future. Subject to the limitations discussed below, we could, in the future, enter into certain transactions, including acquisitions, refinancings or other recapitalizations, that would not constitute a Change of Control under the Indenture, but that could increase the amount of indebtedness outstanding at such time or otherwise affect our capital structure or credit ratings. Restrictions on our ability to incur additional Indebtedness are contained in the covenants described under “Certain covenants—Limitation on Indebtedness and Preferred Stock” and “Certain covenants—Limitation on Liens.” Such restrictions in the Indenture can be waived only with the consent of the holders of a majority in principal amount of the Notes then outstanding. Except for the limitations contained in such covenants, however, the Indenture will not contain any covenants or provisions that may afford holders of the Notes protection in the event of a highly leveraged transaction.

The definition of “Change of Control” includes a disposition of all or substantially all of the property and assets of the Company and its Restricted Subsidiaries taken as a whole to any Person. Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise established definition of the phrase under applicable law. Accordingly, in certain circumstances there may be a degree of uncertainty as to whether a particular transaction

S-38

would involve a disposition of “all or substantially all” of the property or assets of a Person. As a result, it may be unclear as to whether a Change of Control has occurred and whether a holder of Notes may require the Company to make an offer to repurchase the Notes as described above. The Chancery Court of Delaware raised the possibility that a Change of Control occurring as a result of a failure to have Continuing Directors comprising a majority of the Board of Directors may be unenforceable on public policy grounds.

The provisions under the Indenture relative to our obligation to make an offer to repurchase the Notes as a result of a Change of Control may be waived or modified or terminated with the written consent of the holders of a majority in principal amount of the Notes then outstanding (including consents obtained in connection with a tender offer or exchange offer for the Notes) prior to the occurrence of such Change of Control.

Certain covenants

Limitation on Indebtedness and Preferred Stock

The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, Incur any Indebtedness (including Acquired Indebtedness) and the Company will not permit any of its Restricted Subsidiaries to issue Preferred Stock; provided, however, that the Company may Incur Indebtedness and any of the Subsidiary Guarantors may Incur Indebtedness and issue Preferred Stock if on the date thereof:

(1) the Consolidated Coverage Ratio for the Company and its Restricted Subsidiaries is at least 2.25 to 1.00, determined on a pro forma basis (including a pro forma application of proceeds); and

(2) no Default will have occurred or be continuing or would occur as a consequence of Incurring the Indebtedness or transactions relating to such Incurrence.

The first paragraph of this covenant will not prohibit the Incurrence of the following Indebtedness:

(1) Indebtedness of the Company or a Subsidiary Guarantor Incurred pursuant to one or more Credit Facilities in an aggregate amount not to exceed the greater of (a) $500.0 million or (b) an amount equal to the sum of $225.0 million and 30.0% of the Company’s Adjusted Consolidated Net Tangible Assets determined as of the date of the Incurrence of such Indebtedness after giving effect to the application of the proceeds therefrom, in each case outstanding at any one time;

(2) Guarantees by the Company or Subsidiary Guarantors of Indebtedness of the Company or a Subsidiary Guarantor, as the case may be, Incurred in accordance with the provisions of the Indenture; provided that in the event such Indebtedness that is being Guaranteed is a Subordinated Obligation or a Guarantor Subordinated Obligation, then the related Guarantee shall be subordinated in right of payment to the Notes or the Subsidiary Guarantee to at least the same extent as the Indebtedness being Guaranteed, as the case may be;

(3) Indebtedness of the Company owing to and held by any Restricted Subsidiary or Indebtedness of a Restricted Subsidiary owing to and held by the Company or any Restricted Subsidiary; provided, however, that (i) any subsequent issuance or transfer of Capital Stock or any other event which results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary of the Company and (ii) any sale or other transfer of

S-39

any such Indebtedness to a Person other than the Company or a Restricted Subsidiary of the Company shall be deemed, in each case, to constitute an Incurrence of such Indebtedness by the Company or such Subsidiary, as the case may be;

(4) Indebtedness represented by (a) the Notes issued on the Issue Date and all Subsidiary Guarantees, (b) any Indebtedness (other than the Indebtedness described in clauses (1), (2) and 4(a)) outstanding on the Issue Date after giving effect to the Transactions (including the Existing Senior Notes) and (c) any Refinancing Indebtedness Incurred in respect of any Indebtedness described in this clause (4) or clause (5) or Incurred pursuant to the first paragraph of this covenant;

(5) Indebtedness of a Person that becomes a Restricted Subsidiary or is acquired by the Company or a Restricted Subsidiary or merged into the Company or a Restricted Subsidiary in accordance with the Indenture and outstanding on the date on which such Person became a Restricted Subsidiary or was acquired by or was merged into the Company or such Restricted Subsidiary (other than Indebtedness Incurred (a) to provide all or any portion of the funds utilized to consummate the transaction or series of related transactions pursuant to which such Person became a Restricted Subsidiary or was otherwise acquired by or was merged into the Company or a Restricted Subsidiary or (b) otherwise in connection with, or in contemplation of, such acquisition); provided, however, that at the time such Person becomes a Restricted Subsidiary or is acquired by or was merged into the Company or a Restricted Subsidiary, the Company would have been able to Incur $1.00 of additional Indebtedness pursuant to the first paragraph of this covenant after giving effect to the Incurrence of such Indebtedness pursuant to this clause (5);

(6) the Incurrence by the Company or any Restricted Subsidiary of Indebtedness represented by Capitalized Lease Obligations, mortgage financings or purchase money obligations, in each case Incurred for the purpose of financing all or any part of the purchase price or cost of construction or improvements or carrying costs of property used in the business of the Company or such Restricted Subsidiary, and Refinancing Indebtedness Incurred to Refinance any Indebtedness Incurred pursuant to this clause (6) in an aggregate outstanding principal amount which, when taken together with the principal amount of all other Indebtedness Incurred pursuant to this clause (6) and then outstanding, will not exceed $20.0 million at any time outstanding;

(7) Permitted Acquisition Indebtedness;

(8) Indebtedness Incurred in respect of (a) self-insurance obligations, bid, appeal, reimbursement, performance, surety and similar bonds and completion guarantees provided by the Company or a Restricted Subsidiary in the ordinary course of business and any Guarantees or letters of credit functioning as or supporting any of the foregoing bonds or obligations and (b) obligations represented by letters of credit for the account of the Company or a Restricted Subsidiary in order to provide security for workers’ compensation claims (in the case of clauses (a) and (b) other than for an obligation for money borrowed);

(9) the Incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness arising from Guarantees of Indebtedness of joint ventures at any time outstanding not to exceed the greater of $10.0 million or 1.0% of the Company’s Adjusted Consolidated Net Tangible Assets determined as of the date of the Incurrence of such Indebtedness after giving pro forma effect to such Incurrence and the application of proceeds therefrom;

(10) Capital Stock (other than Disqualified Stock) of the Company or of any of the Subsidiary Guarantors; and

S-40

(11) in addition to the items referred to in clauses (1) through (10) above, Indebtedness of the Company and its Subsidiary Guarantors in an aggregate outstanding principal amount which, when taken together with the principal amount of all other Indebtedness Incurred pursuant to this clause (11) and then outstanding, will not at any time exceed the greater of $35.0 million or 2.5% of the Company’s Adjusted Consolidated Net Tangible Assets, determined as of the date of Incurrence of such Indebtedness after giving effect to such Incurrence and the application of the proceeds therefrom.

For purposes of determining compliance with, and the outstanding principal amount of any particular Indebtedness Incurred pursuant to and in compliance with, this covenant:

(1) in the event an item of that Indebtedness meets the criteria of more than one of the types of Indebtedness described in the first and second paragraphs of this covenant, the Company, in its sole discretion, will classify such item of Indebtedness on the date of Incurrence and, subject to clause (2) below may later classify, reclassify or redivide all or a portion of such item of Indebtedness, in any manner that complies with this covenant;

(2) all Indebtedness outstanding on the date of the Indenture under the Senior Secured Credit Agreement shall be deemed Incurred on the Issue Date under clause (1) of the second paragraph of this covenant;

(3) Guarantees of, or obligations in respect of letters of credit supporting, Indebtedness which is otherwise included in the determination of a particular amount of Indebtedness shall not be included;

(4) if obligations in respect of letters of credit are Incurred pursuant to a Credit Facility and are being treated as Incurred pursuant to clause (1) of the second paragraph above and the letters of credit relate to other Indebtedness, then such other Indebtedness shall not be included;

(5) the principal amount of any Disqualified Stock of the Company or a Restricted Subsidiary, or Preferred Stock of a Restricted Subsidiary that is not a Subsidiary Guarantor, will be equal to the greater of the maximum mandatory redemption or repurchase price (not including, in either case, any redemption or repurchase premium) or the liquidation preference thereof;

(6) Indebtedness permitted by this covenant need not be permitted solely by reference to one provision permitting such Indebtedness but may be permitted in part by one such provision and in part by one or more other provisions of this covenant permitting such Indebtedness; and

(7) the amount of Indebtedness issued at a price that is less than the principal amount thereof will be equal to the amount of the liability in respect thereof determined in accordance with GAAP.

Accrual of interest, accrual of dividends, the amortization of debt discount or the accretion of accreted value, the payment of interest in the form of additional Indebtedness, the payment of dividends in the form of additional shares of Preferred Stock or Disqualified Stock and unrealized losses or charges in respect of Hedging Obligations (including those resulting from the application of ASC 815) will not be deemed to be an Incurrence of Indebtedness for purposes of this covenant. The amount of any Indebtedness outstanding as of any date shall be (i) the accreted value thereof in the case of any Indebtedness issued with original issue discount and (ii) the principal amount or liquidation preference thereof, together with any interest thereon that is more than 30 days past due, in the case of any other Indebtedness.

S-41

If at any time an Unrestricted Subsidiary becomes a Restricted Subsidiary, any Indebtedness of such Subsidiary shall be deemed to be Incurred by a Restricted Subsidiary as of such date (and, if such Indebtedness is not permitted to be Incurred as of such date under this “Limitation on Indebtedness and Preferred Stock” covenant, the Company shall be in Default of this covenant).

For purposes of determining compliance with any U.S. dollar-denominated restriction on the Incurrence of Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was Incurred, in the case of term Indebtedness, or first committed, in the case of revolving credit Indebtedness; provided that if such Indebtedness is Incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced. Notwithstanding any other provision of this covenant, the maximum amount of Indebtedness that the Company may Incur pursuant to this covenant shall not be deemed to be exceeded solely as a result of fluctuations in the exchange rate of currencies. The principal amount of any Indebtedness Incurred to refinance other Indebtedness, if Incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such Refinancing Indebtedness is denominated that is in effect on the date of such refinancing.

The Indenture will not treat (1) unsecured Indebtedness as subordinated or junior to secured Indebtedness merely because it is unsecured or (2) senior Indebtedness as subordinated or junior to any other senior Indebtedness merely because it has a junior priority with respect to the same collateral.

Limitation on Restricted Payments

The Company will not, and will not permit any of its Restricted Subsidiaries, directly or indirectly, to:

(1) declare or pay any dividend or make any payment or distribution on or in respect of the Company’s Capital Stock (including any payment or distribution in connection with any merger or consolidation involving the Company or any of its Restricted Subsidiaries) except:

(a) dividends or distributions by the Company payable solely in Capital Stock of the Company (other than Disqualified Stock) or in options, warrants or other rights to purchase such Capital Stock of the Company; and

(b) dividends or distributions payable to the Company or a Restricted Subsidiary and if such Restricted Subsidiary is not a Wholly-Owned Subsidiary, to minority stockholders (or owners of an equivalent interest in the case of a Subsidiary that is an entity other than a corporation) so long as the Company or a Restricted Subsidiary receives at least its pro rata share of such dividend or distribution;

(2) purchase, redeem, defease, retire or otherwise acquire for value any Capital Stock of the Company or any direct or indirect parent of the Company held by Persons other than the Company or a Restricted Subsidiary (other than in exchange for Capital Stock of the Company (other than Disqualified Stock));

(4) make any Restricted Investment in any Person;

(any such dividend, distribution, purchase, redemption, repurchase, defeasance, other acquisition, retirement or Restricted Investment referred to in clauses (1) through (4) shall be referred to herein as a “Restricted Payment”), if at the time the Company or such Restricted Subsidiary makes such Restricted Payment:

(a) a Default shall have occurred and be continuing (or would result therefrom);

(b) the Company is not able to Incur an additional $1.00 of Indebtedness pursuant to the covenant described under the first paragraph under “—Limitation on Indebtedness and Preferred Stock” after giving effect, on a pro forma basis, to such Restricted Payment; or

(c) the aggregate amount of such Restricted Payment and all other Restricted Payments declared or made subsequent to the Issue Date would exceed the sum of:

(i) 50% of Consolidated Net Income for the period (treated as one accounting period) from April 1, 2011 to the end of the most recent fiscal quarter ending prior to the date of such Restricted Payment for which internal financial statements are in existence (or, in case such Consolidated Net Income is a deficit, minus 100% of such deficit);

(ii) 100% of the aggregate Net Cash Proceeds and the fair market value (as determined by the Company’s Board of Directors in good faith) of property or securities other than cash (including Capital Stock of Persons engaged primarily in the Oil and Gas Business or assets used in the Oil and Gas Business), in each case received by the Company from the issue or sale of its Capital Stock (other than Disqualified Stock) or other capital contributions subsequent to the Issue Date (other than Net Cash Proceeds received from an issuance or sale of such Capital Stock to (x) management, employees, directors or any direct or indirect parent of the Company, to the extent such Net Cash Proceeds have been used to make a Restricted Payment pursuant to clause (5)(a) of the next succeeding paragraph, (y) a Subsidiary of the Company or (z) an employee stock ownership plan, option plan or similar trust (to the extent such sale to an employee stock ownership plan, option plan or similar trust is financed by loans from or Guaranteed by the Company or any Restricted Subsidiary unless such loans have been repaid with cash on or prior to the date of determination));

(iii) the amount by which Indebtedness of the Company or its Restricted Subsidiaries is reduced on the Company’s balance sheet upon the conversion or exchange (other than by a Wholly-Owned Subsidiary of the Company) subsequent to the Issue Date of any Indebtedness of the Company or its Restricted Subsidiaries convertible or exchangeable for Capital Stock (other than Disqualified Stock) of the Company (less the amount of any

S-43

cash, or the fair market value of any other property (other than such Capital Stock), distributed by the Company upon such conversion or exchange), together with the net proceeds, if any, received by the Company or any of its Restricted Subsidiaries upon such conversion or exchange; and

(iv) the amount equal to the aggregate net reduction in Restricted Investments made by the Company or any of its Restricted Subsidiaries in any Person after the Issue Date resulting from:

(A) repurchases, repayments or redemptions of such Restricted Investments by such Person, proceeds realized upon the sale of such Restricted Investment (other than to a Subsidiary of the Company), repayments of loans or advances or other transfers of assets (including by way of dividend or distribution) by such Person to the Company or any Restricted Subsidiary;

(B) the redesignation of Unrestricted Subsidiaries as Restricted Subsidiaries (valued in each case as provided in the definition of “Investment”) not to exceed, in the case of any Unrestricted Subsidiary, the amount of Investments previously made by the Company or any Restricted Subsidiary in such Unrestricted Subsidiary, which amount in each case under this clause (iv) was included in the calculation of the amount of Restricted Payments; provided, however, that no amount will be included under this clause (iv) to the extent it is already included in Consolidated Net Income; and

(C) the sale by the Company or any Restricted Subsidiary (other than to the Company or a Restricted Subsidiary) of all or a portion of the Capital Stock of an Unrestricted Subsidiary or a distribution from an Unrestricted Subsidiary or a dividend from an Unrestricted Subsidiary (whether any such distribution or dividend is made with proceeds from the issuance by such Unrestricted Subsidiary of its Capital Stock or otherwise).

The provisions of the preceding paragraph will not prohibit:

(1) any Restricted Payment made by exchange for, or out of the proceeds of the substantially concurrent sale of, Capital Stock of the Company (other than Disqualified Stock and other than Capital Stock issued or sold to a Subsidiary or an employee stock ownership plan or similar trust to the extent such sale to an employee stock ownership plan or similar trust is financed by loans from or Guaranteed by the Company or any Restricted Subsidiary unless such loans have been repaid with cash on or prior to the date of determination) or a substantially concurrent cash capital contribution received by the Company from its shareholders; provided, however, that (a) such Restricted Payment will be excluded from subsequent calculations of the amount of Restricted Payments and (b) the Net Cash Proceeds from such sale of Capital Stock or capital contribution will be excluded from clause (c)(ii) of the preceding paragraph;

(3) any purchase, repurchase, redemption, defeasance or other acquisition or retirement of Disqualified Stock of the Company or a Restricted Subsidiary made by exchange for, or out of the proceeds of the substantially concurrent sale of, Disqualified Stock of the Company or such Restricted Subsidiary, as the case may be, that, in each case, is permitted to be Incurred pursuant to the covenant described under “—Limitation on Indebtedness and Preferred Stock”; provided, however, that such purchase, repurchase, redemption, defeasance, acquisition or retirement will be excluded from subsequent calculations of the amount of Restricted Payments;

(4) dividends paid or distributions made within 60 days after the date of declaration if at such date of declaration such dividend or distribution would have complied with this covenant; provided, however, that such dividends and distributions will be included in subsequent calculations of the amount of Restricted Payments; and provided further, however, that for purposes of clarification, this clause (4) shall not include cash payments in lieu of the issuance of fractional shares included in clause (9) below;

S-46

In the event that a Restricted Payment meets the criteria of more than one of the exceptions described in (1) through (12) above or is entitled to be made pursuant to the first paragraph above, the Company shall, in its sole discretion, classify such Restricted Payment.

As of the Issue Date, only Penn Virginia Holding Corp., Penn Virginia Oil & Gas Corporation, Penn Virginia Oil & Gas GP LLC, Penn Virginia Oil & Gas LP LLC, Penn Virginia Oil & Gas, L.P., Penn Virginia MC Corporation, Penn Virginia MC Energy L.L.C. and Penn Virginia MC Operating Company L.L.C. will be Restricted Subsidiaries. Certain other Subsidiaries of the Company that do not currently guarantee the Senior Secured Credit Agreement or the Existing Senior Notes will be Unrestricted Subsidiaries as of the Issue Date. We will not permit any Unrestricted Subsidiary to become a Restricted Subsidiary except pursuant to the last sentence of the definition of “Unrestricted Subsidiary.” For the purpose of designating any Restricted Subsidiary as an Unrestricted Subsidiary, all outstanding Investments by the Company and its Restricted Subsidiaries (except to the extent repaid) in the Subsidiary so designated will be deemed to be Restricted Payments in an amount determined as set forth in the last sentence of the definition of “Investment.” Such designation will be permitted only if a Restricted Payment in such amount would be permitted at such time, whether pursuant to the first paragraph of this covenant or under clause (12) of the second paragraph of this covenant, or pursuant to the definition of “Permitted Investments,” and if such Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. Unrestricted Subsidiaries will not be subject to any of the restrictive covenants set forth in the Indenture.

Limitation on Liens

The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, Incur or suffer to exist any Lien (the “Initial Lien”) other than Permitted Liens upon any of its property or assets (including Capital Stock of Restricted Subsidiaries), including any income or profits therefrom, whether owned on the date of the Indenture or acquired after that date, which Lien is securing any Indebtedness, unless contemporaneously with the Incurrence of such Liens effective provision is made to secure the Indebtedness due under the Notes or, in respect of Liens on any Restricted Subsidiary’s property or assets, any Subsidiary Guarantee of such Restricted Subsidiary, equally and ratably with (or senior in priority to in the case of Liens with respect to Subordinated Obligations or Guarantor Subordinated Obligations, as the case may be) the Indebtedness secured by such Lien for so long as such Indebtedness is so secured.

Any Lien created for the benefit of the holders of the Notes pursuant to the preceding paragraph shall provide by its terms that such Lien shall be automatically and unconditionally released and discharged upon the release and discharge of the Initial Lien.

Limitation on restrictions on distributions from Restricted Subsidiaries

The Company will not, and will not permit any Restricted Subsidiary to, create or otherwise cause or permit to exist or become effective any consensual encumbrance or consensual restriction on the ability of any Restricted Subsidiary to:

(1) pay dividends or make any other distributions on its Capital Stock or pay any Indebtedness or other obligations owed to the Company or any Restricted Subsidiary (it being understood that the priority of any Preferred Stock in receiving dividends or liquidating distributions prior to dividends or liquidating distributions being paid on Common Stock shall not be deemed a restriction on the ability to make distributions on Capital Stock);

S-47

(2) make any loans or advances to the Company or any Restricted Subsidiary (it being understood that the subordination of loans or advances made to the Company or any Restricted Subsidiary to other Indebtedness Incurred by the Company or any Restricted Subsidiary shall not be deemed a restriction on the ability to make loans or advances); or

(3) sell, lease or transfer any of its property or assets to the Company or any Restricted Subsidiary.

The preceding provisions will not prohibit:

(i) any encumbrance or restriction pursuant to or by reason of an agreement in effect at or entered into on the Issue Date, including, without limitation, the indenture governing the Existing Senior Notes, the indenture governing the Convertible Notes and the Indenture, in each case as in effect on such date;

(ii) any encumbrance or restriction with respect to a Person pursuant to or by reason of an agreement relating to any Capital Stock or Indebtedness Incurred by a Person on or before the date on which such Person was acquired by the Company or another Restricted Subsidiary (other than Capital Stock or Indebtedness Incurred as consideration in, or to provide all or any portion of the funds utilized to consummate, the transaction or series of related transactions pursuant to which such Person was acquired by the Company or a Restricted Subsidiary or in contemplation of the transaction) and outstanding on such date; provided that any such encumbrance or restriction shall not extend to any assets or property of the Company or any other Restricted Subsidiary other than the assets and property so acquired;

(iii) encumbrances and restrictions contained in contracts entered into in the ordinary course of business, not relating to any Indebtedness, and that do not, individually or in the aggregate, detract from the value of, or from the ability of the Company and the Restricted Subsidiaries to realize the value of, property or assets of the Company or any Restricted Subsidiary in any manner material to the Company or any Restricted Subsidiary;

(iv) any encumbrance or restriction with respect to an Unrestricted Subsidiary pursuant to or by reason of an agreement that the Unrestricted Subsidiary is a party to entered into before the date on which such Unrestricted Subsidiary became a Restricted Subsidiary; provided that such agreement was not entered into in anticipation of the Unrestricted Subsidiary becoming a Restricted Subsidiary and any such encumbrance or restriction shall not extend to any assets or property of the Company or any other Restricted Subsidiary other than the assets and property so acquired;

(v) with respect to any Foreign Subsidiary, any encumbrance or restriction contained in the terms of any Indebtedness or any agreement pursuant to which such Indebtedness was Incurred if either (1) the encumbrance or restriction applies only in the event of a payment default or a default with respect to a financial covenant in such Indebtedness or agreement or (2) the Company determines that any such encumbrance or restriction will not materially affect the Company’s ability to make principal or interest payments on the Notes, as determined in good faith by the Board of Directors of the Company, whose determination shall be conclusive;

(vi) any encumbrance or restriction with respect to a Restricted Subsidiary pursuant to an agreement effecting a refunding, replacement or refinancing of Indebtedness Incurred pursuant to an agreement referred to in clauses (i) through (v) or clause (xii) of this

S-48

paragraph or this clause (vi) or contained in any amendment, restatement, modification, renewal, supplemental, refunding, replacement or refinancing of an agreement referred to in clauses (i) through (v) or clause (xii) of this paragraph or this clause (vi); provided that the encumbrances and restrictions with respect to such Restricted Subsidiary contained in any such agreement taken as a whole are no less favorable in any material respect to the holders of the Notes than the encumbrances and restrictions contained in the agreements governing the Indebtedness being refunded, replaced or refinanced;

(vii) in the case of clause (3) of the first paragraph of this covenant, any encumbrance or restriction:

(a) that restricts in a customary manner the subletting, assignment or transfer of any property or asset that is subject to a lease (including leases governing leasehold interests or farm-in agreements or farm-out agreements relating to leasehold interests in Oil and Gas Properties), license or similar contract, or the assignment or transfer of any such lease (including leases governing leasehold interests or farm-in agreements or farm-out agreements relating to leasehold interests in Oil and Gas Properties), license (including, without limitation, licenses of intellectual property) or other contract;

(b) contained in mortgages, pledges or other security agreements permitted under the Indenture securing Indebtedness of the Company or a Restricted Subsidiary to the extent such encumbrances or restrictions restrict the transfer of the property subject to such mortgages, pledges or other security agreements;

(c) contained Hedging Obligations permitted from time to time under the Indenture;

(d) pursuant to customary provisions restricting dispositions of real property interests set forth in any reciprocal easement agreements of the Company or any Restricted Subsidiary;

(viii) (a) purchase money obligations for property acquired in the ordinary course of business and (b) Capitalized Lease Obligations permitted under the Indenture, in each case, that impose encumbrances or restrictions of the nature described in clause (3) of the first paragraph of this covenant on the property so acquired;

(ix) any encumbrance or restriction with respect to a Restricted Subsidiary (or any of its property or assets) imposed pursuant to an agreement entered into for the direct or indirect sale or disposition of all or a portion of the Capital Stock or assets of such Restricted Subsidiary (or the property or assets that are subject to such restriction) pending the closing of such sale or disposition;

(x) any customary encumbrances or restrictions imposed pursuant to any agreement of the type described in the definition of “Permitted Business Investment”;

(xi) encumbrances or restrictions arising or existing by reason of applicable law or any applicable rule, regulation or order;

S-49

(xii) other Indebtedness of the Company or any of its Restricted Subsidiaries permitted to be Incurred pursuant to an agreement entered into subsequent to the Issue Date in accordance with the covenant described under the caption “—Limitation on Indebtedness and Preferred Stock”; provided that the provisions relating to such encumbrance or restriction contained in such Indebtedness are not materially less favorable to the Company taken as a whole, as determined by the Board of Directors of the Company in good faith, than the provisions contained in the Senior Secured Credit Agreement and in the Indenture as in effect on the Issue Date;

(xiii) the issuance of Preferred Stock by a Restricted Subsidiary or the payment of dividends thereon in accordance with the terms thereof; provided that issuance of such Preferred Stock is permitted pursuant to the covenant described under the caption “—Limitation on Indebtedness and Preferred Stock” and the terms of such Preferred Stock do not expressly restrict the ability of a Restricted Subsidiary to pay dividends or make any other distributions on its Capital Stock (other than requirements to pay dividends or liquidation preferences on such Preferred Stock prior to paying any dividends or making any other distributions on such other Capital Stock);

(xiv) supermajority voting requirements existing under corporate charters, bylaws, stockholders agreements and similar documents and agreements;

(xvi) the Senior Secured Credit Agreement as in effect as of the Issue Date, and any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings thereof; provided that such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings are no more restrictive with respect to such dividend and other payment restrictions than those contained in the Senior Secured Credit Agreement as in effect on the Issue Date.

Limitation on sales of assets and Subsidiary stock

The Company will not, and will not permit any of its Restricted Subsidiaries to, make any Asset Disposition unless:

(1) the Company or such Restricted Subsidiary, as the case may be, receives consideration at the time of such Asset Disposition at least equal to the fair market value (such fair market value to be determined on the date of contractually agreeing to such Asset Disposition), as determined in good faith by the Board of Directors (including as to the value of all non-cash consideration), of the shares and assets subject to such Asset Disposition;

(2) (a) at least 75% of the consideration received by the Company or such Restricted Subsidiary, as the case may be, from such Asset Disposition is in the form of cash or Cash Equivalents or Additional Assets, or any combination thereof or (b) the fair market value of all forms of consideration other than those in clause (a) since the Issue Date which does not exceed in the aggregate 10% of the Company’s Adjusted Consolidated Net Tangible Assets of the Company measured at the time the determination is made; and

S-50

(3) except as provided in the next paragraph, an amount equal to 100% of the Net Available Cash from such Asset Disposition is applied, within one year from the later of the date of such Asset Disposition or the receipt of such Net Available Cash, by the Company or such Restricted Subsidiary, as the case may be:

(a) to the extent the Company or any Restricted Subsidiary, as the case may be, elects (or is required by the terms of any Indebtedness), to prepay, repay, redeem or purchase Indebtedness of the Company under the Senior Secured Credit Agreement, any other Indebtedness of the Company or a Subsidiary Guarantor that is secured by a Lien permitted to be Incurred under the Indenture or Indebtedness (other than Disqualified Stock) of any Wholly-Owned Subsidiary that is not a Subsidiary Guarantor; provided, however, that, in connection with any prepayment, repayment, redemption or purchase of Indebtedness pursuant to this clause (a), the Company or such Restricted Subsidiary will retire such Indebtedness and will cause the related commitment (if any) to be permanently reduced in an amount equal to the principal amount so prepaid, repaid, redeemed or purchased; or

(b) to invest in Additional Assets;

provided that pending the final application of any such Net Available Cash in accordance with this covenant, the Company and its Restricted Subsidiaries may temporarily reduce Indebtedness or otherwise invest such Net Available Cash in any manner not prohibited by the Indenture.

Any Net Available Cash from Asset Dispositions that is not applied or invested as provided in the preceding paragraph will be deemed to constitute “Excess Proceeds.” Not later than the day following the date that is one year from the later of the date of such Asset Disposition or the receipt of such Net Available Cash, if the aggregate amount of Excess Proceeds exceeds $20.0 million, the Company will be required to make an offer (“Asset Disposition Offer”) to all holders of Notes and, to the extent required by the terms of other Pari Passu Indebtedness, to all holders of other Pari Passu Indebtedness outstanding with similar provisions requiring the Company to make an offer to purchase such Pari Passu Indebtedness with the proceeds from any Asset Disposition (“Pari Passu Notes”) to purchase the maximum principal amount of Notes and any such Pari Passu Notes to which the Asset Disposition Offer applies that may be purchased out of the Excess Proceeds, at an offer price in cash in an amount equal to 100% of the principal amount (or, in the event such Pari Passu Indebtedness of the Company was issued with significant original issue discount, 100% of the accreted value thereof) of the Notes and Pari Passu Notes plus accrued and unpaid interest, if any (or in respect of such Pari Passu Indebtedness, such lesser price, if any, as may be provided for by the terms of such Indebtedness), to the date of purchase (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date), in accordance with the procedures set forth in the Indenture or the agreements governing the Pari Passu Notes, as applicable, in each case in a minimum principal amount of $2,000 and integral multiples of $1,000 in excess of $2,000. If the aggregate principal amount of Notes surrendered by holders thereof and other Pari Passu Notes surrendered by holders or lenders, collectively, exceeds the amount of Excess Proceeds, the Trustee shall select the Notes to be purchased on a pro rata basis on the basis of the aggregate principal amount of tendered Notes and Pari Passu Notes. To the extent that the aggregate amount of Notes and Pari Passu Notes so validly tendered and not properly withdrawn pursuant to an Asset Disposition Offer is less than the Excess Proceeds, the Company may use any remaining Excess Proceeds for general corporate purposes, subject to the other covenants contained in the Indenture. Upon completion of such Asset Disposition Offer, the amount of Excess Proceeds shall be reset at zero.

S-51

The Asset Disposition Offer will remain open for a period of 20 Business Days following its commencement, except to the extent that a longer period is required by applicable law (the “Asset Disposition Offer Period”). No later than five Business Days after the termination of the Asset Disposition Offer Period (the “Asset Disposition Purchase Date”), the Company will purchase the principal amount of Notes and Pari Passu Notes required to be purchased pursuant to this covenant (the “Asset Disposition Offer Amount”) or, if less than the Asset Disposition Offer Amount has been so validly tendered, all Notes and Pari Passu Notes validly tendered in response to the Asset Disposition Offer.

If the Asset Disposition Purchase Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest, if any, will be paid to the Person in whose name a Note is registered at the close of business on such record date, and no further interest will be payable to holders who tender Notes pursuant to the Asset Disposition Offer.

On or before the Asset Disposition Purchase Date, the Company will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Asset Disposition Offer Amount of Notes and Pari Passu Notes or portions of Notes and Pari Passu Notes so validly tendered and not properly withdrawn pursuant to the Asset Disposition Offer, or if less than the Asset Disposition Offer Amount has been validly tendered and not properly withdrawn, all Notes and Pari Passu Notes so validly tendered and not properly withdrawn, in each case in a minimum principal amount of $2,000 and integral multiples of $1,000 in excess of $2,000. The Company will deliver to the Trustee an Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Company in accordance with the terms of this covenant and, in addition, the Company will deliver all certificates and notes required, if any, by the agreements governing the Pari Passu Notes. The Company or the paying agent, as the case may be, will promptly (but in any case not later than five Business Days after the termination of the Asset Disposition Offer Period) mail or deliver to each tendering holder of Notes or holder or lender of Pari Passu Notes, as the case may be, an amount equal to the purchase price of the Notes or Pari Passu Notes so validly tendered and not properly withdrawn by such holder or lender, as the case may be, and accepted by the Company for purchase, and the Company will promptly issue a new Note, and the Trustee, upon delivery of an Officers’ Certificate from the Company, will authenticate and mail or deliver such new Note to such holder, in a principal amount equal to any unpurchased portion of the Note surrendered; provided that each such new Note will be in a minimum principal amount of $2,000 or an integral multiple of $1,000 in excess of $2,000. In addition, the Company will take any and all other actions required by the agreements governing the Pari Passu Notes. Any Note not so accepted will be promptly mailed or delivered by the Company to the holder thereof. The Company will publicly announce the results of the Asset Disposition Offer on the Asset Disposition Purchase Date.

The Company will comply, to the extent applicable, with the requirements of Rule 14e-1 of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Notes pursuant to the Indenture. To the extent that the provisions of any securities laws or regulations conflict with provisions of this covenant, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Indenture by virtue of its compliance with such securities laws or regulations.

For the purposes of clause (2) of the first paragraph of this covenant, the following will be deemed to be cash:

(1) the assumption by the transferee of Indebtedness (other than Subordinated Obligations or Disqualified Stock) of the Company or Indebtedness of a Restricted Subsidiary (other than

S-52

Guarantor Subordinated Obligations or Disqualified Stock of any Restricted Subsidiary that is a Subsidiary Guarantor) and the release of the Company or such Restricted Subsidiary from all liability on such Indebtedness in connection with such Asset Disposition (or in lieu of such a release, the agreement of the acquirer or its parent company to indemnify and hold the Company or such Restricted Subsidiary harmless from and against any loss, liability or cost in respect of such assumed Indebtedness, in which case the Company will, without further action, be deemed to have applied such deemed cash to Indebtedness in accordance with clause (3)(a) of the first paragraph of this covenant; and

(2) securities, notes or other obligations received by the Company or any Restricted Subsidiary from the transferee that are converted by the Company or such Restricted Subsidiary into cash within 180 days after receipt thereof.

Notwithstanding the foregoing, the 75% limitation referred to in clause (2) of the first paragraph of this covenant shall be deemed satisfied with respect to any Asset Disposition in which the cash or Cash Equivalents portion of the consideration received therefrom, determined in accordance with the foregoing provision on an after-tax basis, is equal to or greater than what the after-tax proceeds would have been had such Asset Disposition complied with the aforementioned 75% limitation.

The requirement of clause (3)(b) of the first paragraph of this covenant above shall be deemed to be satisfied if an agreement (including a lease, whether a capital lease or an operating lease) committing to make the acquisitions or expenditures referred to therein is entered into by the Company or its Restricted Subsidiary within the specified time period and such Net Available Cash is subsequently applied in accordance with such agreement within six months following such agreement.

Limitation on Affiliate Transactions

The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, enter into, make, amend or conduct any transaction (including making a payment to, the purchase, sale, lease or exchange of any property, or the rendering of any service), contract, agreement or understanding with or for the benefit of any Affiliate of the Company (an “Affiliate Transaction”) unless such Affiliate Transaction complies with the Company’s corporate governance principles and:

(1) the terms of such Affiliate Transaction are no less favorable to the Company or such Restricted Subsidiary, as the case may be, than those that could be obtained in a comparable transaction at the time of such transaction in arm’s-length dealings with a Person who is not such an Affiliate;

(2) if such Affiliate Transaction involves an aggregate consideration in excess of $10.0 million, the terms of such transaction have been approved by a majority of the members of the Board of Directors of the Company and by a majority of the members of such Board having no personal stake in such transaction, if any (and such majority or majorities, as the case may be, determines that such Affiliate Transaction satisfies the criteria in clause (1) above); and

(3) if such Affiliate Transaction involves an aggregate consideration in excess of $25.0 million, the Board of Directors of the Company has received a written opinion from an independent investment banking, accounting or appraisal firm of nationally recognized standing that such Affiliate Transaction is fair, from a financial standpoint, to the Company or such Restricted Subsidiary or is not materially less favorable than those that could reasonably be expected to be obtained in a comparable transaction at such time on an arm’s-length basis from a Person that is not an Affiliate.

S-53

The preceding paragraph will not apply to:

(1) any Restricted Payment permitted to be made pursuant to the covenant described under “—Limitation on Restricted Payments” or any Permitted Investment;

(2) any issuance of Capital Stock (other than Disqualified Stock), or other payments, awards or grants in cash, Capital Stock (other than Disqualified Stock) or otherwise pursuant to, or the funding of, employment or severance agreements and other compensation arrangements, options to purchase Capital Stock (other than Disqualified Stock) of the Company, restricted stock plans, long-term incentive plans, stock appreciation rights plans, participation plans or similar employee benefits plans and/or indemnity provided on behalf of officers and employees approved by the Board of Directors of the Company;

(3) loans or advances to employees, officers or directors in the ordinary course of business of the Company or any of its Restricted Subsidiaries;

(4) advances to or reimbursements of employees for moving, entertainment and travel expenses, drawing accounts and similar expenditures in the ordinary course of business of the Company or any of its Restricted Subsidiaries;

(5) any transaction between the Company and a Restricted Subsidiary or between Restricted Subsidiaries and Guarantees issued by the Company or a Restricted Subsidiary for the benefit of the Company or a Restricted Subsidiary, as the case may be, in accordance with “—Limitation on Indebtedness and Preferred Stock”;

(6) any transaction with a joint venture or similar entity which would constitute an Affiliate Transaction solely because the Company or a Restricted Subsidiary owns, directly or indirectly, an Equity Interest in or otherwise controls such joint venture or similar entity;

(7) the issuance or sale of any Capital Stock (other than Disqualified Stock) of the Company or the receipt by the Company of any capital contribution from its shareholders;

(8) indemnities of officers, directors and employees of the Company or any of its Restricted Subsidiaries permitted by bylaw or statutory provisions and any employment agreement or other employee compensation plan or arrangement entered into in the ordinary course of business by the Company or any of its Restricted Subsidiaries;

(9) the payment of reasonable compensation and fees paid to, and indemnity provided on behalf of, officers or directors of the Company or any Restricted Subsidiary;

(10) the performance of obligations of the Company or any of its Restricted Subsidiaries under the terms of any agreement to which the Company or any of its Restricted Subsidiaries is a party as of or on the Issue Date, as these agreements may be amended, modified, supplemented, extended or renewed from time to time; provided, however, that any future amendment, modification, supplement, extension or renewal entered into after the Issue Date will be permitted to the extent that its terms are not materially more disadvantageous, taken as a whole, to the holders of the Notes than the terms of the agreements in effect on the Issue Date;

(11) transactions with customers, clients, suppliers, or purchasers or sellers of goods or services, in each case in the ordinary course of business and otherwise in compliance with the terms of the Indenture which are fair to the Company and its Restricted Subsidiaries, in the reasonable determination of the board of directors of the Company or the senior management thereof, or are on terms at least as favorable as might reasonably have been obtained at such time from an unaffiliated party;

S-54

(12) transactions with a Person (other than an Unrestricted Subsidiary) that is an Affiliate of the Company solely because the Company owns, directly or through a Restricted Subsidiary, an Equity Interest in such Person; and

(13) transactions between the Company or any Restricted Subsidiary and any Person, a director of which is also a director of the Company or any direct or indirect parent company of the Company and such director is the sole cause for such Person to be deemed an Affiliate of the Company or any Restricted Subsidiary; provided, however, that such director shall abstain from voting as a director of the Company or such direct or indirect parent company, as the case may be, on any matter involving such other Person.

Provision of financial information

The Indenture will provide that, whether or not the Company is subject to the reporting requirements of Section 13 or Section 15(d) of the Exchange Act, to the extent not prohibited by the Exchange Act, the Company will file with the SEC, and make available to the Trustee and the registered holders of the Notes without cost to any holder, the annual reports and the information, documents and other reports (or copies of such portions of any of the foregoing as the SEC may by rules and regulations prescribe) that are specified in Sections 13 and 15(d) of the Exchange Act and applicable to a U.S. corporation within the time periods specified therein with respect to an accelerated filer. In the event that the Company is not permitted to file such reports, documents and information with the SEC pursuant to the Exchange Act, the Company will nevertheless make available such Exchange Act information to the Trustee and the holders of the Notes without cost to any holder as if the Company were subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act within the time periods specified therein with respect to a non-accelerated filer.

So long as the Company continues to have designated certain of its Subsidiaries as Unrestricted Subsidiaries, then the financial information required will include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, and in Management’s Discussion and Analysis of Financial Condition and Results of Operations, of the financial condition and results of operations of the Company and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of the Company.

The availability of the foregoing materials on the SEC’s website or on the Company’s website shall be deemed to satisfy the foregoing delivery obligations.

Delivery of such reports, information and documents to the Trustee is for informational purposes only, and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of their covenants hereunder (as to which the Trustee is entitled to rely exclusive on Officers’ Certificates).

Merger and consolidation

The Company will not consolidate with or merge with or into or wind up into (whether or not the Company is the surviving corporation), or convey, transfer or lease all or substantially all its assets in one or more related transactions to, any Person, unless:

(1) the resulting, surviving or transferee Person (the “Successor Company”) will be a corporation, partnership, trust or limited liability company organized and existing under the laws of the

S-55

United States of America, any State of the United States or the District of Columbia and the Successor Company (if not the Company) will expressly assume, by supplemental indenture, executed and delivered to the Trustee, in form reasonably satisfactory to the Trustee, all the obligations of the Company under the Notes and the Indenture;

(2) immediately after giving effect to such transaction (and treating any Indebtedness that becomes an obligation of the Successor Company or any Subsidiary of the Successor Company as a result of such transaction as having been Incurred by the Successor Company or such Subsidiary at the time of such transaction), no Default shall have occurred and be continuing;

(3) either (A) immediately after giving effect to such transaction, the Successor Company would be able to Incur at least an additional $1.00 of Indebtedness pursuant to the first paragraph of the covenant described under “—Limitation on Indebtedness and Preferred Stock” or (B) immediately after giving effect to such transaction on a pro forma basis and any related financing transactions as if the same had occurred at the beginning of the applicable four quarter period, the Consolidated Coverage Ratio of the Company is equal to or greater than the Consolidated Coverage Ratio of the Company immediately before such transaction;

(4) each Subsidiary Guarantor (unless it is the other party to the transactions above, in which case clause (1) shall apply) shall have by supplemental indenture confirmed that its Subsidiary Guarantee shall apply to such Person’s obligations in respect of the Indenture and the Notes shall continue to be in effect; and

(5) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, merger or transfer and such supplemental indenture (if any) comply with the Indenture.

For purposes of this covenant, the sale, lease, conveyance, assignment, transfer or other disposition of all or substantially all of the properties and assets of one or more Subsidiaries of the Company, which properties and assets, if held by the Company instead of such Subsidiaries, would constitute all or substantially all of the properties and assets of the Company on a consolidated basis, shall be deemed to be the transfer of all or substantially all of the properties and assets of the Company.

The Successor Company will succeed to, and be substituted for, and may exercise every right and power of, the Company under the Indenture; and its predecessor Company, except in the case of a lease of all or substantially all of its assets, will be released from the obligation to pay the principal of and interest on the Notes.

Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise established definition of the phrase under applicable law. Accordingly, in certain circumstances there may be a degree of uncertainty as to whether a particular transaction would involve “all or substantially all” of the property or assets of a Person.

Notwithstanding the preceding clause (3), (x) any Restricted Subsidiary may consolidate with, merge into or transfer all or part of its properties and assets to the Company and the Company may consolidate with, merge into or transfer all or part of its properties and assets to a Wholly-Owned Subsidiary and (y) the Company may merge with an Affiliate incorporated solely for the purpose of reincorporating the Company in another jurisdiction; provided that, in the case of a Restricted Subsidiary that consolidates with, merges into or transfers all or part of its properties and assets to the Company, the Company will not be required to comply with the preceding clause (5).

S-56

In addition, the Company will not permit any Subsidiary Guarantor to consolidate with or merge with or into, and will not permit the conveyance, transfer or lease of substantially all of the assets of any Subsidiary Guarantor to, any Person (other than the Company or another Subsidiary Guarantor) unless:

(1) (a) the resulting, surviving or transferee Person will be a corporation, partnership, trust or limited liability company organized and existing under the laws of the United States of America, any State of the United States or the District of Columbia and such Person (if not such Subsidiary Guarantor) will expressly assume, by supplemental indenture, executed and delivered to the Trustee, all the obligations of such Subsidiary Guarantor under its Subsidiary Guarantee and (b) immediately after giving effect to such transaction (and treating any Indebtedness that becomes an obligation of the resulting, surviving or transferee Person or any Restricted Subsidiary as a result of such transaction as having been Incurred by such Person or such Restricted Subsidiary at the time of such transaction), no Default shall have occurred and be continuing; or

(2) the transaction is made in compliance with the covenants described under “Subsidiary guarantees” and “Certain Covenants—Limitation on sales of assets and Subsidiary stock.”

Future subsidiary guarantors

The Indenture will provide that the Company will cause each Restricted Subsidiary that Guarantees any Indebtedness under a Credit Facility or other capital markets Indebtedness, other than a Foreign Subsidiary created or acquired by the Company or one or more of its Restricted Subsidiaries, to execute and deliver to the Trustee a Subsidiary Guarantee pursuant to which such Subsidiary Guarantor will unconditionally Guarantee, on a joint and several basis, the full and prompt payment of the principal of, premium, if any, and interest, if any, on the Notes on a senior basis; provided that any Restricted Subsidiary that constitutes an Immaterial Subsidiary need not become a Subsidiary Guarantor until such time as it ceases to be an Immaterial Subsidiary.

Payments for consent

Neither the Company nor any of its Restricted Subsidiaries will, directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fees or otherwise, to any holder of any Notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of the Indenture or the Notes unless such consideration is offered to be paid or is paid to all holders of the Notes that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or amendment.

Covenant termination

From and after the occurrence of an Investment Grade Rating Event, the Company and its Restricted Subsidiaries will no longer be subject to the provisions of the Indenture described above under the following headings:

• “—Limitation on Indebtedness and Preferred Stock,”

• “—Limitation on Restricted Payments,”

• “—Limitation on restrictions on distributions from Restricted Subsidiaries,”

• “—Limitation on sales of assets and Subsidiary stock,”

• “—Limitation on Affiliate Transactions,” and

S-57

• Clause (3) of “—Merger and consolidation”

(collectively, the “Eliminated Covenants”). As a result, after the date on which the Company and its Restricted Subsidiaries are no longer subject to the Eliminated Covenants, the Notes will be entitled to substantially reduced covenant protection.

After the foregoing covenants have been terminated, the Company may not designate any of its Subsidiaries as Unrestricted Subsidiaries pursuant to the second sentence of the definition of “Unrestricted Subsidiary.”

Events of default

Each of the following is an Event of Default:

(1) default in any payment of interest on any Note when due, continued for 30 days;

(2) default in the payment of principal of or premium, if any, on any Note when due at its Stated Maturity, upon optional redemption, upon required repurchase, upon declaration of acceleration or otherwise;

(3) failure by the Company or any Subsidiary Guarantor to comply with its obligations under “Certain covenants—Merger and consolidation”;

(4) failure by the Company to comply for 30 days after notice as provided below with any of its obligations under the covenant described under “Change of Control” above or under the covenants described under “Certain covenants” above (in each case, other than a failure to purchase Notes which will constitute an Event of Default under clause (2) above and other than a failure to comply with “Certain covenants—Merger and consolidation” which is covered by clause (3));

(5) failure by the Company to comply for 60 days (or 180 days in the case of a Reporting Failure) after notice as provided below with its other agreements contained in the Indenture;

(6) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of its Restricted Subsidiaries), other than Indebtedness owed to the Company or a Restricted Subsidiary, whether such Indebtedness or guarantee now exists, or is created after the date of the Indenture, which default:

(a) is caused by a failure to pay principal of, or interest or premium, if any, on such Indebtedness prior to the expiration of the grace period provided in such Indebtedness (and any extensions of any grace period) (“payment default”); or

(b) results in the acceleration of such Indebtedness prior to its maturity (the “cross acceleration provision”);

and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a payment default or the maturity of which has been so accelerated, aggregates $20.0 million or more;

(7) certain events of bankruptcy, insolvency or reorganization of the Company or a Significant Subsidiary or group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary (the “bankruptcy provisions”);

S-58

(8) failure by the Company or any Significant Subsidiary or group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary to pay final judgments aggregating in excess of $20.0 million (to the extent not covered by insurance by a reputable and creditworthy insurer as to which the insurer has not disclaimed coverage), which judgments are not paid or discharged, and there shall be any period of 60 consecutive days following entry of such final judgment or decree during which a stay of enforcement of such final judgment or decree, by reason of pending appeal or otherwise, shall not be in effect (the “judgment default provision”); or

(9) any Subsidiary Guarantee of a Significant Subsidiary or group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries) would constitute a Significant Subsidiary ceases to be in full force and effect (except as contemplated by the terms of the Indenture) or is declared null and void in a judicial proceeding or any Subsidiary Guarantor that is a Significant Subsidiary or group of Subsidiary Guarantors that, taken together (as of the latest audited consolidated financial statements of the Company and its Restricted Subsidiaries) would constitute a Significant Subsidiary denies or disaffirms its obligations under the Indenture or its Subsidiary Guarantee.

However, a default under clauses (4) and (5) of this paragraph will not constitute an Event of Default until the Trustee or the holders of 25% in principal amount of the outstanding Notes notify the Company in writing and, in the case of a notice given by the holders, the Trustee of the default and the Company does not cure such default within the time specified in clauses (4) and (5) of this paragraph after receipt of such notice.

If an Event of Default (other than an Event of Default described in clause (7) above) occurs and is continuing, the Trustee by notice to the Company, or the holders of at least 25% in principal amount of the outstanding Notes by notice to the Company and the Trustee, may, and the Trustee at the request of such holders shall, declare the principal of, premium, if any, accrued and unpaid interest, if any, on all the Notes to be due and payable. If an Event of Default described in clause (7) above occurs and is continuing, the principal of, premium, if any, accrued and unpaid interest, if any, on all the Notes will become and be immediately due and payable without any declaration or other act on the part of the Trustee or any holders. The holders of a majority in principal amount of the outstanding Notes may waive all past defaults (except with respect to nonpayment of principal, premium or interest, if any) and rescind any such acceleration with respect to the Notes and its consequences if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) all existing Events of Default, other than the nonpayment of the principal of, premium, if any, and interest on the Notes that have become due solely by such declaration of acceleration, have been cured or waived.

Notwithstanding the foregoing, if an Event of Default specified in clause (6) above shall have occurred and be continuing, such Event of Default and any consequential acceleration (to the extent not in violation of any applicable law) shall be automatically rescinded if (i) the Indebtedness that is the subject of such Event of Default has been repaid or (ii) if the default relating to such Indebtedness is waived or cured and if such Indebtedness has been accelerated, then the holders thereof have rescinded their declaration of acceleration in respect of such Indebtedness.

Subject to the provisions of the Indenture relating to the duties of the Trustee, if an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under the Indenture at the request or direction of any of the holders unless such

S-59

holders have offered to the Trustee reasonable indemnity or security against any loss, liability or expense. Except to enforce the right to receive payment of principal, premium, if any, or interest when due, no holder may pursue any remedy with respect to the Indenture or the Notes unless:

(1) such holder has previously given the Trustee notice that an Event of Default is continuing;

(2) holders of at least 25% in principal amount of the outstanding Notes have requested the Trustee to pursue the remedy;

(3) such holders have offered the Trustee reasonable security or indemnity against any loss, liability or expense;

(4) the Trustee has not complied with such request within 60 days after the receipt of the request and the offer of security or indemnity; and

(5) the holders of a majority in principal amount of the outstanding Notes have not waived such Event of Default or otherwise given the Trustee a direction that, in the opinion of the Trustee, is inconsistent with such request within such 60-day period.

Subject to certain restrictions, the holders of a majority in principal amount of the outstanding Notes are given the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. The Indenture provides that in the event an Event of Default has occurred and is continuing, the Trustee will be required in the exercise of its powers to use the degree of care that a prudent person would use in the conduct of its own affairs. The Trustee, however, may refuse to follow any direction that conflicts with law or the Indenture or that the Trustee determines is unduly prejudicial to the rights of any other holder or that would involve the Trustee in personal liability. Prior to taking any action under the Indenture, the Trustee will be entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action.

The Trustee may withhold notice if and so long as a committee of trust officers of the Trustee in good faith determines that withholding notice is in the interests of the holders. In addition, the Company is required to deliver to the Trustee, within 120 days after the end of each fiscal year, a certificate indicating whether the signers thereof know of any Default that occurred during the previous year. The Company also is required to deliver to the Trustee, within 30 days after the occurrence thereof, written notice of any events which would constitute certain Defaults, their status and what action the Company is taking or proposing to take in respect thereof.

Amendments and waivers

Subject to certain exceptions, the Indenture and the Notes may be amended or supplemented with the consent of the holders of a majority in principal amount of the Notes then outstanding (including without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes) and, subject to certain exceptions, any past default or compliance with any provisions may be waived with the consent of the holders of a majority in principal amount of the Notes then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes). However, without the consent of each holder of an outstanding Note affected, no amendment may, among other things:

(1) reduce the principal amount of Notes whose holders must consent to an amendment, supplement or waiver;

S-60

(2) reduce the stated rate of or extend the stated time for payment of interest on any Note;

(3) reduce the principal of or extend the Stated Maturity of any Note;

(4) reduce the premium payable upon the redemption of any Note as described above under “Optional redemption,” or change the time at which any Note may be redeemed as described above under “Optional redemption,” (other than the provisions described above under “Change of Control” and “—Certain covenants—Limitation on sales of assets or Subsidiary stock”);

(5) make any Note payable in money other than that stated in the Note;

(6) impair the right of any holder to receive payment of, premium, if any, principal of and interest on such holder’s Notes on or after the due dates therefor or to institute suit for the enforcement of any payment on or with respect to such holder’s Notes;

(7) make any change in the amendment provisions which require each holder’s consent or in the waiver provisions;

(8) modify the Subsidiary Guarantees in any manner adverse to the holders of the Notes; or

(9) make any change to or modify the ranking of the Notes that would adversely affect the holders.

Notwithstanding the foregoing, without the consent of any holder, the Company, the Guarantors and the Trustee may amend the Indenture and the Notes to:

(1) cure any ambiguity, omission, defect, mistake or inconsistency;

(2) provide for the assumption by a successor corporation of the obligations of the Company or any Subsidiary Guarantor under the Indenture;

(3) provide for uncertificated Notes in addition to or in place of certificated Notes (provided that the uncertificated Notes are issued in registered form for purposes of Section 163(f) of the Code, or in a manner such that the uncertificated Notes are described in Section 163(f)(2)(B) of the Code);

(4) add Guarantees with respect to the Notes, including Subsidiary Guarantees, or release a Subsidiary Guarantor from its Subsidiary Guarantee and terminate such Subsidiary Guarantee; provided that the release and termination is in accord with the applicable provisions of the Indenture;

(5) secure the Notes or Subsidiary Guarantees;

(6) add to the covenants of the Company or a Subsidiary Guarantor for the benefit of the holders or surrender any right or power conferred upon the Company or a Subsidiary Guarantor;

(7) make any change that does not adversely affect the rights of any holder;

(8) comply with any requirement of the SEC in connection with the qualification of the Indenture under the Trust Indenture Act; or

(9) provide for the succession of a successor Trustee.

S-61

The consent of the holders is not necessary under the Indenture to approve the particular form of any proposed amendment. It is sufficient if such consent approves the substance of the proposed amendment. A consent to any amendment or waiver under the Indenture by any holder of Notes given in connection with a tender of such holder’s Notes will not be rendered invalid by such tender. After an amendment under the Indenture becomes effective, the Company is required to mail to the holders a notice briefly describing such amendment. However, the failure to give such notice to all the holders, or any defect in the notice, will not impair or affect the validity of the amendment.

Defeasance

The Company at any time may terminate all its obligations under the Notes and the Indenture (“legal defeasance”), except for certain obligations, including those respecting the defeasance trust and obligations to register the transfer or exchange of the Notes, to replace mutilated, destroyed, lost or stolen Notes and to maintain a registrar and paying agent in respect of the Notes. If the Company exercises its legal defeasance option, the Subsidiary Guarantees in effect at such time will terminate.

The Company at any time may terminate its obligations described under “Change of Control” and under covenants described under “Certain covenants” (other than clauses (1), (2), (4) and (5) of “Merger and consolidation”), the operation of the cross-default upon a payment default, cross-acceleration provisions, the bankruptcy provisions with respect to Significant Subsidiaries, the judgment default provision, the Subsidiary Guarantee provision described under “Events of default” above and the limitations contained in clause (3) under “Certain covenants—Merger and consolidation” above, and the Company and the Subsidiary Guarantors may terminate the obligations of the Subsidiary Guarantors to provide the Subsidiary Guarantees, which thereupon shall be automatically released (“covenant defeasance”).

The Company may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option. If the Company exercises its legal defeasance option, payment of the Notes may not be accelerated because of an Event of Default with respect to the Notes. If the Company exercises its covenant defeasance option, payment of the Notes may not be accelerated because of an Event of Default specified in clause (4), (5), (6), (7) (with respect only to Significant Subsidiaries), (8) or (9) under “Events of default” above or because of the failure of the Company to comply with clause (3) under “Certain covenants—Merger and consolidation” above.

In order to exercise either defeasance option, the Company must, among other things, irrevocably deposit in trust (the “defeasance trust”) with the Trustee money or U.S. Government Obligations for the payment of principal, premium, if any, and interest on the Notes to redemption or maturity, as the case may be, and must comply with certain other conditions, including delivery to the Trustee of an Opinion of Counsel (subject to customary exceptions and exclusions) to the effect that holders of the Notes will not recognize income, gain or loss for federal income tax purposes as a result of such deposit and defeasance and will be subject to Federal income tax on the same amount and in the same manner and at the same times as would have been the case if such deposit and defeasance had not occurred. In the case of legal defeasance only, such Opinion of Counsel must be based on a ruling of the Internal Revenue Service or other change in applicable federal income tax law.

S-62

Satisfaction and discharge

The Indenture will be discharged and will cease to be of further effect as to all Notes issued thereunder, when either:

(1) all Notes that have been authenticated (except lost, stolen or destroyed Notes that have been replaced or paid and Notes for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust) have been delivered to the Trustee for cancellation, or

(2) all Notes that have not been delivered to the Trustee for cancellation have become due and payable or will become due and payable within one year by reason of the giving of a notice of redemption or otherwise and the Company or any Subsidiary Guarantor has irrevocably deposited or caused to be irrevocably deposited with the Trustee as trust funds in trust solely for such purpose, cash in U.S. dollars, U.S. Government Obligations, or a combination thereof, in such amounts as will be sufficient without consideration of any reinvestment of interest, to pay and discharge the entire indebtedness on the Notes not delivered to the Trustee for cancellation for principal and accrued interest to the date of maturity or redemption, and in each case certain other requirements set forth in the Indenture are satisfied.

No personal liability of directors, officers, employees and stockholders

No director, officer, employee, incorporator, stockholder, member, partner or trustee of the Company or any Subsidiary Guarantor, as such, shall have any liability for any obligations of the Company or any Subsidiary Guarantor under the Notes, the Indenture or the Subsidiary Guarantees or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes.

Concerning the trustee

Wells Fargo Bank, National Association will be the Trustee under the Indenture and has been appointed by the Company as registrar and paying agent with regard to the Notes.

Governing law

The Indenture provides that it and the Notes will be governed by, and construed in accordance with, the laws of the State of New York.

(1) if the Company or any Restricted Subsidiary:

(a) has Incurred any Indebtedness since the beginning of such period that remains outstanding on such date of determination or if the transaction giving rise to the need to calculate the Consolidated Coverage Ratio is an Incurrence of Indebtedness, Consolidated EBITDAX and Consolidated Interest Expense for such period will be calculated after giving effect on a pro forma basis to such Indebtedness and the use of proceeds thereof as if such Indebtedness had been Incurred on the first day of such period and such proceeds had been applied as of such date (except that in making such computation, the amount of Indebtedness under any revolving Credit Facility outstanding on the date of such calculation will be deemed to be (i) the average daily balance of such Indebtedness during such four fiscal quarters or such shorter period for which such facility was outstanding or (ii) if such revolving Credit Facility was created after the end of such four fiscal quarters, the average daily balance of such Indebtedness during the period from the date of creation of such revolving Credit Facility to the date of such calculation, in each case, provided that such average daily balance shall take into account any repayment of Indebtedness under such revolving Credit Facility as provided in clause (b)); or

(b) has repaid, repurchased, defeased or otherwise discharged any Indebtedness since the beginning of the period, including with the proceeds of such new Indebtedness, that is

S-69

no longer outstanding on such date of determination or if the transaction giving rise to the need to calculate the Consolidated Coverage Ratio involves a discharge of Indebtedness (in each case other than Indebtedness Incurred under any revolving Credit Facility unless such Indebtedness has been permanently repaid and the related commitment terminated), Consolidated EBITDAX and Consolidated Interest Expense for such period will be calculated after giving effect on a pro forma basis to such discharge of such Indebtedness as if such discharge had occurred on the first day of such period;

(2) if, since the beginning of such period, the Company or any Restricted Subsidiary has made any Asset Disposition or if the transaction giving rise to the need to calculate the Consolidated Coverage Ratio is such an Asset Disposition, the Consolidated EBITDAX for such period will be reduced by an amount equal to the Consolidated EBITDAX (if positive) directly attributable to the assets which are the subject of such Asset Disposition for such period or increased by an amount equal to the Consolidated EBITDAX (if negative) directly attributable thereto for such period and Consolidated Interest Expense for such period shall be reduced by an amount equal to the Consolidated Interest Expense directly attributable to any Indebtedness of the Company or any Restricted Subsidiary repaid, repurchased, defeased or otherwise discharged with respect to the Company and its continuing Restricted Subsidiaries in connection with or with the proceeds from such Asset Disposition for such period (or, if the Capital Stock of any Restricted Subsidiary is sold, the Consolidated Interest Expense for such period directly attributable to the Indebtedness of such Restricted Subsidiary to the extent the Company and its continuing Restricted Subsidiaries are no longer liable for such Indebtedness after such sale);

(3) if, since the beginning of such period, the Company or any Restricted Subsidiary (by merger or otherwise) has made an Investment in any Restricted Subsidiary (or any Person which becomes a Restricted Subsidiary or is merged with or into the Company or a Restricted Subsidiary) or an acquisition (or will have received a contribution) of assets, including any acquisition or contribution of assets occurring in connection with a transaction causing a calculation to be made hereunder, which constitutes all or substantially all of a company, division, operating unit, segment, business, group of related assets or line of business, Consolidated EBITDAX and Consolidated Interest Expense for such period will be calculated after giving pro forma effect thereto (including the Incurrence of any Indebtedness) as if such Investment or acquisition or contribution had occurred on the first day of such period; and

(4) if, since the beginning of such period, any Person (that subsequently became a Restricted Subsidiary or was merged with or into the Company or any Restricted Subsidiary since the beginning of such period) made any Asset Disposition or any Investment or acquisition of assets that would have required an adjustment pursuant to clause (2) or (3) above if made by the Company or a Restricted Subsidiary during such period, Consolidated EBITDAX and Consolidated Interest Expense for such period will be calculated after giving pro forma effect thereto as if such Asset Disposition or Investment or acquisition of assets had occurred on the first day of such period.

For purposes of this definition, whenever pro forma effect is to be given to any calculation under this definition, the pro forma calculations will be determined in good faith by a responsible financial or accounting officer of the Company; provided that such officer may in his or her discretion include any reasonably identifiable and factually supportable pro forma changes to Consolidated EBITDAX, including any pro forma expenses and cost reductions, that have occurred or in the judgment of such officer are reasonably expected to occur within 12 months of the date of the applicable transaction (regardless of whether such expense or cost reduction or any other

S-70

operating improvements could then be reflected properly in pro forma financial statements prepared in accordance with Regulation S-X under the Securities Act or any other regulation or policy of the SEC). If any Indebtedness bears a floating rate of interest and is being given pro forma effect, the interest expense on such Indebtedness will be calculated as if the average rate in effect from the beginning of such period to the date of determination had been the applicable rate for the entire period (taking into account any Interest Rate Agreement applicable to such Indebtedness, but if the remaining term of such Interest Rate Agreement is less than 12 months, then such Interest Rate Agreement shall only be taken into account for that portion of the period equal to the remaining term thereof). If any Indebtedness that is being given pro forma effect bears an interest rate at the option of the Company, the interest rate shall be calculated by applying such optional rate chosen by the Company. Interest on Indebtedness that may optionally be determined at an interest rate based upon a factor of a prime or similar rate, a eurocurrency interbank offered rate, or other rate, shall be deemed to have been based upon the rate actually chosen, or, if none, then based upon such optional rate chosen as the Company may designate.

“Consolidated EBITDAX” for any period means, without duplication, the Consolidated Net Income for such period, plus the following, without duplication and to the extent deducted (and not added back) in calculating such Consolidated Net Income:

(1) Consolidated Interest Expense;

(2) Consolidated Income Taxes of the Company and its Restricted Subsidiaries;

(3) consolidated depletion and depreciation expense of the Company and its Restricted Subsidiaries;

(4) consolidated amortization expense or impairment charges of the Company and its Restricted Subsidiaries recorded in connection with the application of ASC 350, “Goodwill and Other Intangibles” and ASC 360-10 and 360-20, “Accounting for the Impairment or Disposal of Long Lived Assets”;

(5) other non-cash charges of the Company and its Restricted Subsidiaries (excluding any such non-cash charge to the extent it represents an accrual of or reserve for cash charges in any future period or amortization of a prepaid cash expense that was paid in a prior period not included in the calculation); and

(6) consolidated exploration expense of the Company and its Restricted Subsidiaries,

if applicable for such period; and less, to the extent included in calculating such Consolidated Net Income and in excess of any costs or expenses attributable thereto that were deducted (and not added back) in calculating such Consolidated Net Income, the sum of (x) the amount of deferred revenues that are amortized during such period and are attributable to reserves that are subject to Volumetric Production Payments, (y) amounts recorded in accordance with GAAP as repayments of principal and interest pursuant to Dollar-Denominated Production Payments and (z) other non-cash gains (excluding any non-cash gain to the extent it represents the reversal of an accrual or reserve for a potential cash item that reduced Consolidated EBITDAX in any prior period).

Notwithstanding the preceding sentence, clauses (2) through (6) relating to amounts of a Restricted Subsidiary of a Person will be added to Consolidated Net Income to compute Consolidated EBITDAX of such Person only to the extent (and in the same proportion) that the net income (loss) of such Restricted Subsidiary was included in calculating the Consolidated Net Income of such Person and, to the extent the amounts set forth in clauses (2) through (6) are in excess of those

S-71

necessary to offset a net loss of such Restricted Subsidiary or if such Restricted Subsidiary has net income for such period included in Consolidated Net Income, only if a corresponding amount would be permitted at the date of determination to be dividended to the Company by such Restricted Subsidiary without prior approval (that has not been obtained), pursuant to the terms of its charter and all agreements, instruments, judgments, decrees, orders, statutes, rules and governmental regulations applicable to that Restricted Subsidiary or its stockholders.

“Consolidated Income Taxes” means, with respect to any Person for any period, taxes imposed upon such Person or other payments required to be made by such Person by any governmental authority which taxes or other payments are calculated by reference to the income, profits or capital of such Person or such Person and its Restricted Subsidiaries (to the extent such income or profits were included in computing Consolidated Net Income for such period), regardless of whether such taxes or payments are required to be remitted to any governmental authority.

“Consolidated Interest Expense” means, for any period, the total consolidated interest expense of the Company and its Restricted Subsidiaries, whether paid or accrued, plus, to the extent not included in such interest expense and without duplication:

(1) interest expense attributable to Capitalized Lease Obligations and the interest component of any deferred payment obligations;

(2) amortization of debt discount and debt issuance cost (provided that any amortization of bond premium will be credited to reduce Consolidated Interest Expense unless, pursuant to GAAP, such amortization of bond premium has otherwise reduced Consolidated Interest Expense);

(3) non-cash interest expense;

(4) commissions, discounts and other fees and charges owed with respect to letters of credit and bankers’ acceptance financing;

(5) the interest expense on Indebtedness of another Person that is Guaranteed by the Company or one of its Restricted Subsidiaries or secured by a Lien on assets of the Company or one of its Restricted Subsidiaries, to the extent such Guarantee becomes payable or such Lien becomes subject to foreclosure;

(6) costs associated with Interest Rate Agreements (including amortization of fees); provided, however, that if Interest Rate Agreements result in net benefits rather than costs, such benefits shall be credited to reduce Consolidated Interest Expense unless, pursuant to GAAP, such net benefits are otherwise reflected in Consolidated Net Income;

(7) the consolidated interest expense of such Person and its Restricted Subsidiaries that was capitalized during such period; and

(8) all dividends paid or payable in cash, Cash Equivalents or Indebtedness or accrued during such period on any series of Disqualified Stock of the Company or on Preferred Stock of its Restricted Subsidiaries payable to a party other than the Company or a Wholly-Owned Subsidiary.

minus, to the extent included above, write-off of deferred financing costs (and interest) attributable to Dollar-Denominated Production Payments.

For the purpose of calculating the Consolidated Coverage Ratio in connection with the Incurrence of any Indebtedness described in the final paragraph of the definition of

S-72

“Indebtedness,” the calculation of Consolidated Interest Expense shall include all interest expense (including any amounts described in clauses (1) through (8) above) relating to any Indebtedness of the Company or any Restricted Subsidiary described in the final paragraph of the definition of “Indebtedness.”

“Consolidated Net Income” means, for any period, the aggregate net income (loss) attributable to the Company and its consolidated Subsidiaries determined in accordance with GAAP and before any reduction in respect of Preferred Stock dividends of such Person; provided, however, that there will not be included (to the extent otherwise included therein) in such Consolidated Net Income:

(1) any net income (loss) of any Person (other than the Company) if such Person is not a Restricted Subsidiary, except that:

(a) subject to the limitations contained in clauses (3) and (4) below, the Company’s equity in the net income of any such Person for such period will be included in such Consolidated Net Income up to the aggregate amount of cash actually distributed by such Person during such period to the Company or a Restricted Subsidiary as a dividend or other distribution (subject, in the case of a dividend or other distribution to a Restricted Subsidiary, to the limitations contained in clause (2) below); and

(b) the Company’s equity in a net loss of any such Person for such period will be included in determining such Consolidated Net Income to the extent such loss has been funded with cash from the Company or a Restricted Subsidiary during such period;

(2) any net income (but not loss) of any Restricted Subsidiary if such Subsidiary is subject to restrictions, directly or indirectly, on the payment of dividends or the making of distributions by such Restricted Subsidiary, directly or indirectly, to the Company, except that:

Book-entry, delivery and form

We have obtained the information in this section concerning DTC, Clearstream Banking, S.A., Luxembourg (“Clearstream, Luxembourg”) and Euroclear Bank S.A./N.V., as operator of the Euroclear System (“Euroclear”), and their book-entry systems and procedures from sources that we believe to be reliable. We take no responsibility for an accurate portrayal of this information. In addition, the description of the clearing systems in this section reflects our understanding of the rules and procedures of DTC, Clearstream, Luxembourg and Euroclear as they are currently in effect. Those systems could change their rules and procedures at any time.

The notes will initially be represented by one or more fully registered global notes. Each such global note will be deposited with, or on behalf of, DTC or any successor thereto and registered in the name of Cede & Co. (“DTC’s nominee”). You may hold your interests in the global notes in the United States through DTC, or in Europe through Clearstream, Luxembourg or Euroclear, either as a participant in such systems or indirectly through organizations which are participants in such systems. Clearstream, Luxembourg and Euroclear will hold interests in the global notes on behalf of their respective participating organizations or customers through customers’ securities accounts in Clearstream, Luxembourg’s or Euroclear’s names on the books of their respective depositaries, which in turn will hold those positions in customers’ securities accounts in the depositaries’ names on the books of DTC. Citibank, N.A. will act as depositary for Clearstream, Luxembourg and JPMorgan Chase Bank, N.A. will act as depositary for Euroclear.

So long as DTC or its nominee is the registered owner of the global securities representing the notes, DTC or such nominee will be considered the sole owner and holder of the notes for all purposes of the notes and the indenture. Except as provided below, owners of beneficial interests in the notes will not be entitled to have the notes registered in their names, will not receive or be entitled to receive physical delivery of the notes in definitive form and will not be considered the owners or holders of the notes under the indenture, including for purposes of receiving any reports delivered by us or the trustee pursuant to the indenture. Accordingly, each person owning a beneficial interest in a note must rely on the procedures of DTC or its nominee and, if such person is not a participant, on the procedures of the participant through which such person owns its interest, in order to exercise any rights of a holder of notes.

Unless and until we issue the notes in fully certificated, registered form under the limited circumstances described below under the heading “—Certificated notes:”

• you will not be entitled to receive a certificate representing your interest in the notes;

• all references in this prospectus supplement to actions by holders will refer to actions taken by DTC upon instructions from its direct participants; and

• all references in this prospectus supplement to payments and notices to holders will refer to payments and notices to DTC or Cede & Co., as the registered holder of the notes, for distribution to you in accordance with DTC procedures.

The Depository Trust Company

DTC will act as securities depositary for the notes. The notes will be issued as fully registered notes registered in the name of Cede & Co. DTC is:

• a limited-purpose trust company organized under the New York Banking Law;

• a “banking organization” under the New York Banking Law;

S-93

• a member of the Federal Reserve System;

• a “clearing corporation” under the New York Uniform Commercial Code; and

• a “clearing agency” registered under the provisions of Section 17A of the Exchange Act.

DTC holds securities that its direct participants deposit with DTC. DTC facilitates the settlement among direct participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in direct participants’ accounts, thereby eliminating the need for physical movement of securities certificates.

Direct participants of DTC include securities brokers and dealers (including the underwriters), banks, trust companies, clearing corporations and certain other organizations. DTC is owned by a number of its direct participants. Indirect participants of DTC, such as securities brokers and dealers, banks and trust companies, can also access the DTC system if they maintain a custodial relationship with a direct participant.

Purchases of notes under DTC’s system must be made by or through direct participants, which will receive a credit for the notes on DTC’s records. The ownership interest of each beneficial owner is in turn to be recorded on the records of direct participants and indirect participants. Beneficial owners will not receive written confirmation from DTC of their purchase, but beneficial owners are expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the direct participants or indirect participants through which such beneficial owners entered into the transaction. Transfers of ownership interests in the notes are to be accomplished by entries made on the books of participants acting on behalf of beneficial owners. Beneficial owners will not receive certificates representing their ownership interests in notes, except as provided below in “—Certificated notes.”

To facilitate subsequent transfers, all notes deposited with DTC are registered in the name of DTC’s nominee, Cede & Co. The deposit of notes with DTC and their registration in the name of Cede & Co. effect no change in beneficial ownership. DTC has no knowledge of the actual beneficial owners of the notes. DTC’s records reflect only the identity of the direct participants to whose accounts such notes are credited, which may or may not be the beneficial owners. The participants will remain responsible for keeping account of their holdings on behalf of their customers.

Conveyance of notices and other communications by DTC to direct participants, by direct participants to indirect participants and by direct participants and indirect participants to beneficial owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.

Book-entry format

Under the book-entry format, the paying agent will pay interest or principal payments to Cede & Co., as nominee of DTC. DTC will forward the payment to the direct participants, who will then forward the payment to the indirect participants (including Clearstream, Luxembourg or Euroclear) or to you as the beneficial owner. You may experience some delay in receiving your payments under this system. Neither we, the trustee under the indenture nor any paying agent has any direct responsibility or liability for the payment of principal or interest on the notes to owners of beneficial interests in the notes.

DTC is required to make book-entry transfers on behalf of its direct participants and is required to receive and transmit payments of principal, premium, if any, and interest on the notes. Any direct

S-94

participant or indirect participant with which you have an account is similarly required to make book-entry transfers and to receive and transmit payments with respect to the notes on your behalf. We and the trustee under the indenture have no responsibility for any aspect of the actions of DTC, Clearstream, Luxembourg or Euroclear or any of their direct or indirect participants. In addition, we and the trustee under the indenture have no responsibility or liability for any aspect of the records kept by DTC, Clearstream, Luxembourg, Euroclear or any of their direct or indirect participants relating to or payments made on account of beneficial ownership interests in the notes or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. We also do not supervise these systems in any way.

The trustee will not recognize you as a holder under the indenture, and you can only exercise the rights of a holder indirectly through DTC and its direct participants. DTC has advised us that it will only take action regarding a note if one or more of the direct participants to whom the note is credited directs DTC to take such action and only in respect of the portion of the aggregate principal amount of the notes as to which that participant or participants has or have given that direction. DTC can only act on behalf of its direct participants. Your ability to pledge notes to non-direct participants, and to take other actions, may be limited because you will not possess a physical certificate that represents your notes.

Neither DTC nor Cede & Co. (nor any other DTC nominee) will consent or vote with respect to the notes unless authorized by a direct participant in accordance with DTC’s procedures. Under its usual procedures, DTC will mail an omnibus proxy to us as soon as possible after the record date. The omnibus proxy assigns Cede & Co.’s consenting or voting rights to those direct participants to whose accounts the notes are credited on the record date (identified in a listing attached to the omnibus proxy).

Clearstream, Luxembourg or Euroclear will credit payments to the cash accounts of Clearstream, Luxembourg customers or Euroclear participants in accordance with the relevant system’s rules and procedures, to the extent received by its depositary. These payments will be subject to tax reporting in accordance with relevant United States tax laws and regulations. Clearstream, Luxembourg or the Euroclear operator, as the case may be, will take any other action permitted to be taken by a holder under the indenture on behalf of a Clearstream, Luxembourg customer or Euroclear participant only in accordance with its relevant rules and procedures and subject to its depositary’s ability to effect those actions on its behalf through DTC.

DTC, Clearstream, Luxembourg and Euroclear have agreed to the foregoing procedures in order to facilitate transfers of the notes among participants of DTC, Clearstream, Luxembourg and Euroclear. However, they are under no obligation to perform or continue to perform those procedures, and they may discontinue those procedures at any time.

Transfers within and among book-entry systems

Transfers between DTC’s direct participants will occur in accordance with DTC rules. Transfers between Clearstream, Luxembourg customers and Euroclear participants will occur in accordance with its applicable rules and operating procedures.

DTC will effect cross-market transfers between persons holding directly or indirectly through DTC, on the one hand, and directly or indirectly through Clearstream, Luxembourg customers or Euroclear participants, on the other hand, in accordance with DTC rules on behalf of the relevant European international clearing system by its depositary. However, cross-market transactions will require delivery of instructions to the relevant European international clearing system by the

S-95

counterparty in that system in accordance with its rules and procedures and within its established deadlines (European time). The relevant European international clearing system will, if the transaction meets its settlement requirements, instruct its depositary to effect final settlement on its behalf by delivering or receiving securities in DTC and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Clearstream, Luxembourg customers and Euroclear participants may not deliver instructions directly to the depositaries.

Because of time-zone differences, credits of securities received in Clearstream, Luxembourg or Euroclear resulting from a transaction with a DTC direct participant will be made during the subsequent securities settlement processing, dated the business day following the DTC settlement date. Those credits or any transactions in those securities settled during that processing will be reported to the relevant Clearstream, Luxembourg customer or Euroclear participant on that business day. Cash received in Clearstream, Luxembourg or Euroclear as a result of sales of securities by or through a Clearstream, Luxembourg customer or a Euroclear participant to a DTC direct participant will be received with value on the DTC settlement date but will be available in the relevant Clearstream, Luxembourg or Euroclear cash amount only as of the business day following settlement in DTC.

Although DTC, Clearstream, Luxembourg and Euroclear has agreed to the foregoing procedures in order to facilitate transfers of debt securities among their respective participants, they are under no obligation to perform or continue to perform such procedures and such procedures may be discontinued at any time.

Certificated notes

Unless and until they are exchanged, in whole or in part, for notes in definitive form in accordance with the terms of the notes, the notes may not be transferred except (1) as a whole by DTC to a nominee of DTC or (2) by a nominee of DTC to DTC or another nominee of DTC or (3) by DTC or any such nominee to a successor of DTC or a nominee of such successor.

We will issue notes to you or your nominees, in fully certificated registered form, rather than to DTC or its nominees, only if:

• we advise the trustee in writing that DTC is no longer willing or able to discharge its responsibilities properly or that DTC is no longer a registered clearing agency under the Exchange Act, and the trustee or we are unable to locate a qualified successor within 90 days;

• an event of default has occurred and is continuing under the indenture; or

• we, at our option, elect to terminate the book-entry system through DTC.

If any of the three above events occurs, DTC is required to notify all direct participants that notes in fully certificated registered form are available through DTC. DTC will then surrender the global note representing the notes along with instructions for re-registration. The trustee will re-issue the notes in fully certificated registered form and will recognize the registered holders of the certificated notes as holders under the indenture.

Unless and until we issue the notes in fully certificated, registered form, (1) you will not be entitled to receive a certificate representing your interest in the notes; (2) all references in this prospectus supplement to actions by holders will refer to actions taken by the depositary upon instructions from their direct participants; and (3) all references in this prospectus supplement to

S-96

payments and notices to holders will refer to payments and notices to the depositary, as the registered holder of the notes, for distribution to you in accordance with its policies and procedures.

Same day settlement and payment

We will make payments in respect of the notes represented by the global notes (including principal, premium, if any, and interest) by wire transfer of immediately available funds to the accounts specified by DTC or its nominee. We will make all payments of principal, interest and premium, if any, with respect to certificated notes by wire transfer of immediately available funds to the accounts specified by the holders of the certificated notes or, if no such account is specified, by mailing a check to each such holder’s registered address. The Notes represented by the global notes are expected to be eligible to trade in DTC’s Same-Day Funds Settlement System, and any permitted secondary market trading activity in such notes will, therefore, be required by DTC to be settled in immediately available funds. We expect that secondary trading in any certificated notes will also be settled in immediately available funds.

Because of time zone differences, the securities account of a Clearstream, Luxembourg customer or Euroclear participant purchasing an interest in a global note from another customer or participant will be credited, and any such crediting will be reported to the relevant Clearstream, Luxembourg customer or Euroclear participant, during the securities settlement processing day (which must be a business day for Euroclear and Clearstream) immediately following the settlement date of DTC. DTC has advised us that cash received in Clearstream, Luxembourg or Euroclear as a result of sales of interests in a global note by or through a Clearstream, Luxembourg customer or Euroclear participant to another customer or participant will be received with value on the settlement date of DTC but will be available in the relevant Clearstream, Luxembourg or Euroclear cash account only as of the business day for Euroclear or Clearstream, Luxembourg following DTC’s settlement date.

S-97

Certain U.S. federal income tax consequences

The following discussion summarizes certain U.S. federal income tax considerations that may be relevant to the acquisition, ownership and disposition of the notes. This discussion is based upon the provisions of the Internal Revenue Code of 1986, as amended (the “Code”), applicable U.S. Treasury Regulations promulgated thereunder, judicial authority and administrative interpretations, as of the date of this document, all of which are subject to change, possibly with retroactive effect, or are subject to different interpretations. We cannot assure you that the Internal Revenue Service (the “IRS”) will not challenge one or more of the tax consequences described in this discussion, and we have not obtained, nor do we intend to obtain, a ruling from the IRS or an opinion of counsel with respect to the U.S. federal tax consequences of acquiring, holding or disposing of the notes.

This discussion is limited to holders who purchase the notes in this offering for a price equal to the “issue price” of the notes (i.e., the first price at which a substantial amount of the notes is sold other than to bond houses, brokers or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers) and who hold the notes as capital assets (generally, property held for investment). This discussion does not address the tax considerations arising under the laws of any foreign, state, local or other jurisdiction. In addition, this discussion does not address all tax considerations that may be important to a particular holder in light of the holder’s circumstances, or to certain categories of investors that may be subject to special rules, such as:

• dealers in securities or currencies;

• traders in securities that have elected the mark-to-market method of accounting for their securities;

• U.S. holders (as defined below) whose functional currency is not the U.S. dollar;

• persons holding notes as part of a hedge, straddle, conversion or other “synthetic security” or integrated transaction;

• certain U.S. expatriates;

• financial institutions;

• insurance companies;

• regulated investment companies;

• real estate investment trusts;

• persons subject to the alternative minimum tax;

• entities that are tax-exempt for U.S. federal income tax purposes; and

• partnerships and other pass-through entities and investors therein.

If an entity treated as a partnership for U.S. federal income tax purposes holds notes, the tax treatment of a partner generally will depend upon the status of the partner and the activities of the partnership. If you are a partner of a partnership acquiring the notes, you are urged to consult your own tax advisor about the U.S. federal income tax consequences of acquiring, holding and disposing of the notes.

S-98

INVESTORS CONSIDERING THE PURCHASE OF NOTES ARE URGED TO CONSULT THEIR OWN TAX ADVISORS REGARDING THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP OR DISPOSITION OF THE NOTES UNDER U.S. FEDERAL ESTATE OR GIFT TAX LAWS OR UNDER THE LAWS OF ANY STATE, LOCAL OR FOREIGN JURISDICTION OR UNDER ANY APPLICABLE TAX TREATY.

Effect of certain additional payments

In certain circumstances described under “Description of notes—Optional redemption” and “Description of notes—Change of control,” we may be obligated to pay amounts on the notes that are in excess of stated interest or principal on the notes. Those potential payments may implicate the provisions of the U.S. Treasury Regulations relating to “contingent payment debt instruments.” For purposes of determining whether a debt instrument is a contingent payment debt instrument, contingencies are ignored if, as of the issue date, (i) the likelihood that any such contingency will occur is remote, (ii) the contingencies, in the aggregate, are considered incidental or (iii) in certain circumstances, it is significantly more likely than not that no such contingency will occur. We intend to take the position that the possibility that we would be required to make such excess payments will not cause the notes to be treated as contingent payment debt instruments. If any such additional payments are made to a holder, however, the holder would recognize additional income.

Our position that the notes are not contingent payment debt instruments is binding on a holder, unless the holder disclosures in the manner required by the applicable U.S. Treasury Regulations that it is taking a different position. Our position, however, is not binding on the IRS and it is possible that the IRS may take a different position. In that case, a holder might be required to accrue interest income at a higher rate than the stated interest rate on the notes and to treat as ordinary interest income any gain realized on the taxable disposition of a note.

The remainder of this discussion assumes that the notes will not be treated as contingent payment debt instruments. Investors should consult their own tax advisors regarding the possible application of the contingent payment debt instrument rules to the notes.

Tax consequences to U.S. holders

You are a “U.S. holder” for purposes of this discussion if you are a beneficial owner of a note and you are for U.S. federal income tax purposes:

• an individual who is a U.S. citizen or U.S. resident alien;

• a corporation, or other entity taxable as a corporation for U.S. federal income tax purposes, that was created or organized in or under the laws of the United States, any state thereof or the District of Columbia;

• an estate whose income is subject to U.S. federal income taxation regardless of its source; or

• a trust (i) if a court within the United States is able to exercise primary supervision over the administration of the trust and one or more United States persons have the authority to control all substantial decisions of the trust or (ii) that has a valid election in effect under applicable U.S. Treasury Regulations to be treated as a United States person.

S-99

Interest on the notes

Interest on the notes generally will be taxable to you as ordinary income at the time it is received or accrued in accordance with your regular method of accounting for U.S. federal income tax purposes.

Disposition of notes

You will generally recognize capital gain or loss on the sale, redemption, exchange, retirement or other taxable disposition of a note. This gain or loss will be equal to the difference between your adjusted tax basis in the note and the proceeds you receive (excluding any proceeds attributable to accrued but unpaid stated interest which will be recognized as ordinary interest income to the extent you have not previously included the accrued interest in income). The proceeds you receive will include the amount of any cash and the fair market value of any other property received for the note. Your adjusted tax basis in the note will generally be equal to the amount you paid for the note. The gain or loss will be long-term capital gain or loss if you held the note for more than one year at the time of the sale, redemption, exchange, retirement or other disposition. Long-term capital gains of individuals, estates and trusts generally are subject to a reduced rate of U.S. federal income tax. The deductibility of capital losses may be subject to limitation.

Information reporting and backup withholding

Information reporting will apply to payments of interest on, and the proceeds of the sale or other disposition (including a retirement or redemption) of, notes held by you, and backup withholding may apply to such payments unless you provide the appropriate intermediary with a taxpayer identification number, certified under penalties of perjury, as well as certain other information. Backup withholding is not an additional tax. Any amount withheld under the backup withholding rules is allowable as a credit against your U.S. federal income tax liability, if any, and a refund may be obtained if the amounts withheld exceed your actual U.S. federal income tax liability and you timely provide the required information or appropriate claim form to the IRS.

New legislation relating to net investment income

For taxable years beginning after December 31, 2012, newly-enacted legislation is scheduled to impose a 3.8% tax on the “net investment income” of certain U.S. citizens and resident aliens and on the undistributed “net investment income” of certain estates and trusts. “Net investment income” generally includes, among other items, interest and certain net gain from the disposition of property, such as the notes, less certain deductions.

Prospective holders should consult their tax advisors with respect to the tax consequences of the new legislation described above.

Tax consequences to non-U.S. holders

You are a “non-U.S. holder” for purposes of this discussion if you are a beneficial owner of notes who is an individual, corporation, estate or trust that is not a U.S. holder.

S-100

Interest on the notes

Payments to you of interest on the notes generally will be exempt from withholding of U.S. federal income tax under the “portfolio interest” exemption if you properly certify as to your foreign status as described below, and:

• you do not own, actually or constructively, 10% or more of the total combined voting power of all classes of our stock entitled to vote;

• you are not a “controlled foreign corporation” that is related to us (actually or constructively) through sufficient stock ownership;

• you are not a bank whose receipt of interest on the notes is in connection with an extension of credit made pursuant to a loan agreement entered into in the ordinary course of your trade or business; and

• interest on the notes is not effectively connected with your conduct of a U.S. trade or business.

The portfolio interest exemption and several of the special rules for non-U.S. holders described below generally apply only if you appropriately certify as to your foreign status. You can generally meet this certification requirement by providing a properly executed IRS Form W-8BEN or appropriate substitute form to us or our paying agent. If you hold the notes through a financial institution or other agent acting on your behalf, you may be required to provide appropriate certifications to the agent. Your agent will then generally be required to provide appropriate certifications to us or our paying agent, either directly or through other intermediaries. Special rules apply to foreign partnerships, estates and trusts, and in certain circumstances certifications as to foreign status of partners, trust owners or beneficiaries may have to be provided to us or our paying agent. In addition, special rules apply to qualified intermediaries that enter into withholding agreements with the IRS.

If you cannot satisfy the requirements described above, payments of interest made to you will be subject to U.S. federal withholding tax at a 30% rate, unless you provide us or our paying agent with a properly executed IRS Form W-8BEN (or successor form) claiming an exemption from (or a reduction of) withholding under the benefit of a tax treaty, or the payments of interest are effectively connected with your conduct of a trade or business in the United States and you meet the certification requirements described below. (See “—Tax consequences to non-U.S. holders—Income or gain effectively connected with a U.S. trade or business.”)

Disposition of notes

You generally will not be subject to U.S. federal income tax on any gain realized on the sale, redemption, exchange, retirement or other taxable disposition of a note unless:

• the gain is effectively connected with the conduct by you of a U.S. trade or business; or

• you are an individual who has been present in the United States for 183 days or more in the taxable year of disposition and certain other requirements are met.

If you are a non-U.S. holder described in the first bullet point above, you generally will be subject to U.S. federal income tax in the same manner as a U.S. holder (See “—Tax consequences to non-U.S. holders—Income or gain effectively connected with a U.S. trade or business”). If you are a non-U.S. holder described in the second bullet point above, you will be subject to a flat 30% U.S. federal income tax on the gain derived from the sale or other disposition, which may be offset by U.S. source capital losses.

S-101

Income or gain effectively connected with a U.S. trade or business

If any interest on the notes or gain from the sale, exchange or other taxable disposition of the notes is effectively connected with a U.S. trade or business conducted by you, then the interest income or gain will be subject to U.S. federal income tax at regular graduated income tax rates unless an applicable income tax treaty provides otherwise. Effectively connected income will not be subject to U.S. withholding tax if you satisfy certain certification requirements by providing to us or our paying agent a properly executed IRS Form W-8ECI (or successor form) or W-8BEN (or successor form) claiming an exemption under an applicable income tax treaty. If you are a corporation, that portion of your earnings and profits that is effectively connected with your U.S. trade or business may also be subject to a “branch profits tax” at a 30% rate, although an applicable income tax treaty may provide for a lower rate.

Information reporting and backup withholding

Payments to you of interest on a note, and amounts withheld from such payments, if any, generally will be required to be reported to the IRS and to you. Copies of the information returns reporting such interest may also be made available to the tax authorities in the country in which you reside under the provisions of a treaty or agreement.

United States backup withholding generally will not apply to payments of interest on a note if the certification requirements described in “Tax consequences to non-U.S. holders—Interest on the notes” are met or you otherwise establish an exemption, provided that we do not have actual knowledge or reason to know that you are a United States person.

Payment of the proceeds of a disposition of a note (including a retirement or redemption) effected by the U.S. office of a U.S. or foreign broker will be subject to information reporting requirements and backup withholding unless you properly certify under penalties of perjury as to your foreign status and certain other conditions are met or you otherwise establish an exemption. Information reporting requirements and backup withholding generally will not apply to any payment of the proceeds of the disposition of a note effected outside the United States by a foreign office of a broker. However, unless such a broker has documentary evidence in its records that you are a non-U.S. holder and certain other conditions are met, or you otherwise establish an exemption, information reporting will apply to a payment of the proceeds of the disposition of a note effected outside the United States by such a broker if it has certain relationships with the United States.

Backup withholding is not an additional tax. Any amount withheld under the backup withholding rules is allowable as a credit against your U.S. federal income tax liability, if any, and a refund may be obtained if the amounts withheld exceed your actual U.S. federal income tax liability and you timely provide the required information or appropriate claim form to the IRS.

THE PRECEDING DISCUSSION OF CERTAIN U.S. FEDERAL INCOME TAX CONSEQUENCES IS FOR GENERAL INFORMATION ONLY AND IS NOT TAX ADVICE. WE URGE EACH PROSPECTIVE INVESTOR TO CONSULT ITS OWN TAX ADVISOR REGARDING THE PARTICULAR FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES OF PURCHASING, HOLDING AND DISPOSING OF THE NOTES, INCLUDING THE CONSEQUENCES OF ANY PROPOSED CHANGE IN APPLICABLE LAWS.

S-102

Underwriting

Subject to the terms and conditions in the underwriting agreement between us and the underwriters, for whom J.P. Morgan Securities LLC is acting as representative, we have agreed to sell to each underwriter, and each underwriter has severally agreed to purchase from us, the principal amount of notes that appears opposite its name in the table below:

Underwriter	Principal amount
J.P. Morgan Securities LLC . .	$	120,000,000
Merrill Lynch, Pierce, Fenner & Smith Incorporated		30,000,000
RBC Capital Markets, LLC		30,000,000
Wells Fargo Securities, LLC		30,000,000
Barclays Capital Inc. .		24,000,000

Comerica Securities, Inc.		6,000,000
PNC Capital Markets LLC.		6,000,000
Total	$	300,000,000

The underwriters have agreed to purchase all of the notes if any of them are purchased. The underwriting agreement provides that the obligations of the underwriters to purchase the notes included in this offering are subject to, among other customary conditions, the delivery of certain legal opinions by their counsel. The underwriting agreement also provides that if an underwriter defaults, the purchase commitments of non-defaulting underwriters may also be increased or the offering may be terminated.

The underwriters initially propose to offer the notes to the public at the public offering price that appears on the cover page of this prospectus supplement. The underwriters may offer the notes to selected dealers at the public offering price minus a concession of up to 0.375% of the principal amount. In addition, the underwriters may allow, and those selected dealers may reallow, a concession of up to 0.250% of the principal amount to certain other dealers. After the initial offering, the underwriters may change the public offering price and any other selling terms. The underwriters may offer and sell notes through certain of their affiliates.

In the underwriting agreement, we have agreed that:

• We will not offer or sell any of our debt securities (other than the notes) for a period of 45 days after the date of this prospectus supplement without the prior consent of J.P. Morgan Securities LLC.

• We will pay our expenses related to the offering.

• We will indemnify the underwriters against certain liabilities, including liabilities under the Securities Act, or contribute to payments that the underwriters may be required to make in respect of those liabilities.

The notes are a new issue of securities with no established trading market. We do not intend to apply for the notes to be listed on any securities exchange or to arrange for the notes to be quoted on any quotation system. The underwriters have advised us that they intend to make a market in the notes. However, they are not obligated to do so and they may discontinue any

S-103

market making at any time in their sole discretion. Therefore, we cannot assure you that a liquid trading market will develop for the notes, that you will be able to sell your notes at a particular time or that the prices that you receive when you sell will be favorable.

In relation to each Member State of the European Economic Area which has implemented the Prospectus Directive (each, a “Relevant Member State”), with effect from and including the date on which the Prospectus Directive is implemented in that Relevant Member State (the “Relevant Implementation Date”), each underwriter has not made and will not make an offer of notes to the public in that Relevant Member State other than:

• to any legal entity which is a qualified investor as defined in the Prospectus Directive;

• to fewer than 100 or, if the Relevant Member State has implemented the relevant provision of the 2010 PD Amending Directive, 150, natural or legal persons (other than qualified investors as defined in the Prospectus Directive), as permitted under the Prospectus Directive, subject to obtaining the prior consent of the relevant dealer or dealers nominated by the Company for any such offer; or

• in any other circumstances falling within Article 3(2) of the Prospectus Directive,

provided that no such offer of notes shall require the Company or any underwriter to publish a prospectus pursuant to Article 3 of the Prospectus Directive.

For the purposes of this provision, the expression an “offer of notes to the public” in relation to any notes in any Relevant Member State means the communication in any form and by any means of sufficient information on the terms of the offer and the notes to be offered so as to enable an investor to decide to purchase or subscribe the notes, as the same may be varied in that Member State by any measure implementing the Prospectus Directive in that Member State, the expression “Prospectus Directive” means Directive 2003/71/EC (and amendments thereto, including the 2010 PD Amending Directive, to the extent implemented in the Relevant Member State), and includes any relevant implementing measure in the Relevant Member State and the expression “2010 PD Amending Directive” means Directive 2010/73/EU.

Each underwriter has only communicated or caused to be communicated and will only communicate or cause to be communicated an invitation or inducement to engage in investment activity (within the meaning of Section 21 of the United Kingdom Financial Services and Markets Act 2000 (the “FSMA”)) received by it in connection with the issue or sale of the notes in circumstances in which Section 21(1) of the FSMA does not apply to the Company or the Guarantors; and each underwriter has complied and will comply with all applicable provisions of the FSMA with respect to anything done by it in relation to the notes in, from or otherwise involving the United Kingdom.

In connection with the offering of the notes, the underwriters may engage in overallotments, stabilizing transactions and syndicate covering transactions in accordance with Regulation M under the Exchange Act. Overallotment involves sales in excess of the offering size, which creates a short position for the underwriter. Stabilizing transactions involve bids to purchase the notes in the open market for the purpose of pegging, fixing or maintaining the price of the notes, as applicable. Syndicate covering transactions involve purchases of the notes in the open market after the distribution has been completed in order to cover short positions. Stabilizing transactions and syndicate covering transactions may have the effect of preventing or retarding a decline in the market price of the notes or cause the price of the notes to be higher than it would otherwise be in the absence of those transactions. If any of the underwriters engages in stabilizing or syndicate covering transactions, it may discontinue them at any time.

S-104

Certain of the underwriters and their affiliates have in the past and may in the future provide investment banking, commercial banking, derivative transactions and financial advisory services to us and our affiliates in the ordinary course of business. In particular, affiliates of J.P. Morgan Securities LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated, Wells Fargo Securities, LLC, BNP Paribas Securities Corp., RBC Capital Markets, LLC, BMO Capital Markets Corp., Capital One Southcoast, Inc., Comerica Securities, Inc., PNC Capital Markets LLC and Scotia Capital (USA) Inc. are lenders to us under our Revolver. In addition, Wells Fargo Bank, National Association, an affiliate of Wells Fargo Securities, LLC, is the trustee under the indenture governing the notes offered hereby and the trustee under the indentures governing our 2012 Convertible Notes and our 2016 Senior Notes. Certain of the underwriters or their affiliates are holders of our 2012 Convertible Notes and, accordingly, they will receive a portion of the net proceeds of this offering in connection with the Tender Offer. Furthermore, J.P. Morgan Securities LLC is the dealer manager for the Tender Offer and the solicitation agent for the Consent Solicitation.

We expect that the delivery of the notes will be made against payment therefor on or about April 13, 2011, which is the sixth business day following the date of pricing of the notes (such settlement cycle being herein referred to as “T+6”). Under Rule 15c6-1 under the Exchange Act, trades in the secondary market generally are required to settle in three business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes on the date of pricing of the notes or during the next succeeding two business days will be required, by virtue of the fact that the notes initially will settle in T+6, to specify an alternate settlement cycle at the time of any such trade in order to prevent a failed settlement and should consult their own advisors.

Legal matters

Certain legal matters related to the notes being offered hereby are being passed upon for us by Vinson & Elkins L.L.P., New York, New York. The underwriters will be represented by Cahill Gordon & Reindel LLP, New York, New York. Vinson & Elkins L.L.P. will rely, as to matters of Virginia law, on the opinion of Hunton & Williams LLP, Virginia counsel for the Company.

Engineers

The estimated reserve evaluations and related calculations of Wright & Company, Inc., independent petroleum engineering consultants, included in this prospectus supplement have been include in reliance on the authority of that firm as experts in petroleum engineering.

Exp erts

The consolidated financial statements of Penn Virginia Corporation as of December 31, 2010 and 2009, and for each of the years in the three-year period ended December 31, 2010, and management’s assessment of the effectiveness of internal control over financial reporting as of December 31, 2010 have been incorporated by reference herein and in the registration statement in reliance upon the reports of KPMG LLP, independent registered public accounting firm incorporated by reference herein and in the registration statement and upon the authority of said firm as experts in accounting and auditing.

FORWARD-LOOKING STATEMENTS

Some of the information included in this prospectus, any prospectus supplement and the documents we incorporate by reference herein and therein contain “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Exchange Act. These statements use forward-looking words such as “may,” “will,” “should,” “could,” “achievable,” “anticipate,” “believe,” “expect,” “estimate,” “project” or other words and phrases of similar meaning. These statements discuss goals, intentions and expectations as to future trends, plans, events, results of operations or financial condition or state other “forward-looking” information. A forward-looking statement may include a statement of the assumptions or bases underlying the forward-looking statements. We believe we have chosen these assumptions or bases in good faith and that they are reasonable. However, we caution you that assumed facts or bases almost always vary from actual results, and the differences between assumed facts or bases and actual results can be material, depending on the circumstances. When considering forward-looking statements, you should keep in mind the cautionary statements in this prospectus, any prospectus supplement and the documents we have incorporated by reference, including in our Annual Report on Form 10-K for the year ended December 31, 2010 (our “2010 Annual Report”). These statements reflect our current views with respect to future events and are subject to various risks, uncertainties and assumptions, including, but not limited, to:

• 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

• other risks set forth in Item 1A of our 2010 Annual Report.

Additional information concerning these and other factors can be found in our press releases and public periodic filings with the SEC. Many of the factors that will determine our future results are beyond the ability of management to control or predict. Readers should not place undue reliance on forward-looking statements, which reflect management’s views only as of the date hereof. All forward-looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by the cautionary statements in this paragraph and in the documents incorporated herein by reference. 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.

RISK FACTORS

An investment in our securities involves a significant degree of risk. You should carefully consider the risk factors and all of the other information included in this prospectus, any prospectus supplement and the documents we have incorporated by reference into this prospectus and any prospectus supplement, including those in Item 1A “Risk Factors” in our 2010 Annual Report, as updated by annual, quarterly and other reports and documents we file with the SEC after the date of this prospectus and that are incorporated by reference herein, in evaluating an investment in the securities. If any of these risks were actually to occur, our business, financial condition or results of operations could be materially adversely affected. When we offer and sell any securities pursuant to a prospectus supplement, we may include additional risk factors relevant to such securities in the prospectus supplement.

USE OF PROCEEDS

Unless we inform you otherwise in a prospectus supplement, we intend to use the net proceeds from the sale of securities we are offering for general corporate purposes. This may include, among other things, additions to working capital, repayment or refinancing of existing indebtedness or other corporate obligations, financing of capital expenditures and acquisitions and investment in existing and future projects.

RATIOS OF EARNINGS TO FIXED CHARGES

The following table sets forth our ratio of earnings to fixed charges for each year in the five years ended December 31, 2010. The calculations include us and our subsidiaries.

	Year Ended December 31,
	2010		2009		2008		2007		2006
Ratio of earnings to fixed charges:		*		*		5.3x		2.9x		8.9x

* During 2010 and 2009, earnings were deficient by $49,559 and $165,533, respectively, regarding the coverage of fixed charges.

For purposes of calculating the ratio of earnings to fixed charges:

• “fixed charges” represent interest expense (including amounts capitalized), amortization of debt issuance costs and the portion of rental expense representing the interest factor; and

• “earnings” represent the aggregate of income from continuing operations (before adjustment for income taxes, extraordinary items, income or loss from equity investees and minority interest) plus fixed charges, amortization of capitalized interest and distributed income of equity investees, and less capitalized interest.

No ratio of combined fixed charges and preferred stock dividends is shown because we have no outstanding preferred stock. Therefore, if shown, such ratios would be identical to the ratios of earnings to fixed charges shown above.

DESCRIPTION OF DEBT SECURITIES

General

The debt securities issued using this prospectus will be:

• our general unsecured obligations;

• general unsecured obligations of the Subsidiary Guarantors if they are guaranteed by the Subsidiary Guarantors; and

• either senior debt securities or subordinated debt securities.

The senior debt securities and the subordinated debt securities will be issued under separate indentures among Penn Virginia, as issuer, the Subsidiary Guarantors (if any), and Wells Fargo Bank, National Association (the “Trustee”). The Trustee for each series of debt securities will be identified in the applicable prospectus supplement. Senior debt securities will be issued under an indenture we call the senior indenture, and subordinated debt securities will be issued under an indenture we call the subordinated indenture. We have not restated these agreements in their entirety. We have filed the forms of the indentures as exhibits to the registration statement of which this prospectus is a part. We urge you to read the indentures, because they, and not this description, control your rights as holders of the debt securities.

We will prepare a prospectus supplement and either an indenture supplement or a resolution of our board of directors and accompanying officers’ certificate relating to any series of debt securities that we offer, which will include specific terms relating to some or all of the following:

• the form and title of the debt securities;

• whether the debt securities are senior debt securities or subordinated debt securities and, if subordinated debt securities, the terms of subordination;

• the total principal amount of the debt securities;

• the date or dates on which the debt securities of that series may be issued;

• the percentage of the principal amount at which the debt securities will be issued and any payments which will be due if the maturity of the debt securities is accelerated;

• if convertible into common stock, the terms on which the debt securities are convertible;

• any right we may have to defer payments of interest by extending the dates payments are due and whether interest on those deferred amounts will be payable;

• the dates on which the principal and premium, if any, of the debt securities will be payable;

• the interest rate which the debt securities will bear and the interest payment dates for the debt securities;

• any optional redemption provisions;

• any sinking fund or other provisions that would obligate us to repurchase or otherwise redeem the debt securities;

• whether the debt securities are entitled to the benefits of any guarantees by the Subsidiary Guarantors;

• any changes to or additions to the events of default or covenants contained in the applicable indenture;

• any affirmative or negative covenants relating to such series; and

• any other terms of the debt securities of that series.

6

This description of debt securities will be deemed modified, amended or supplemented by any description of any series of debt securities set forth in a prospectus supplement related to that series.

The prospectus supplement will also describe any material United States federal income tax consequences or other special considerations regarding the applicable series of debt securities, including those relating to:

• debt securities with respect to which payments of principal, premium or interest are determined with reference to an index or formula, including changes in prices of particular securities, currencies or commodities;

• debt securities with respect to which principal, premium or interest is payable in a foreign or composite currency;

• debt securities that are issued at a discount below their stated principal amount, bearing no interest or interest at a rate that at the time of issuance is below market rates; and

• variable rate debt securities that are exchangeable for fixed rate debt securities.

At our option, we may make interest payments by check mailed to the registered holders of debt securities or, if so stated in the applicable prospectus supplement, at the option of a holder by wire transfer to an account designated by the holder.

Unless otherwise provided in the applicable prospectus supplement, fully registered securities maybe transferred or exchanged at the office of the Trustee at which its corporate trust business is principally administered in the United States, subject to the limitations provided in the indenture, without the payment of any service charge, other than any applicable tax or governmental charge.

Senior Debt Securities

The senior debt securities will be unsecured senior obligations and will rank equally with all other senior unsecured and unsubordinated debt. However, the senior debt securities will be effectively subordinated in right of payment to all our secured indebtedness to the extent of the value of the assets securing such indebtedness.

Except as provided in the senior indenture or specified in any authorizing resolution and/or supplemental indenture relating to a series of senior debt securities to be issued, the senior indenture will not limit:

• the amount of additional indebtedness that may rank equally with the senior debt securities; or

• the amount of indebtedness, secured or otherwise, that may be incurred or preferred stock that maybe issued by any of our subsidiaries.

Subordinated Debt Securities

Payment of the principal, interest and any premium on the subordinated debt securities will, to the extent set forth in the subordinated indenture with respect to each series of subordinated debt securities, be subordinated in right of payment to the prior payment in full of all of our senior debt, including the senior debt securities. The prospectus supplement relating to any subordinated debt securities will summarize the subordination provisions of the subordinated indenture applicable to that series including:

• the applicability and effect of such provisions upon any payment or distribution of our assets to creditors upon any liquidation, dissolution, winding-up, reorganization, assignment for the benefit of creditors or marshaling of assets or any bankruptcy, insolvency or similar proceedings;

• the applicability and effect of such provisions in the event of specified defaults with respect to any or certain senior debt, including the circumstances under which and the periods in which we will be prohibited from making payments on the subordinated debt securities; and

7

• the definition of senior debt applicable to the subordinated debt securities of that series.

The prospectus supplement will also describe as of a recent date the approximate amount of senior debt to which the subordinated debt securities of that series will be subordinated.

The failure to make any payment on any of the subordinated debt securities by reason of the subordination provisions of the subordinated indenture will not be construed as preventing the occurrence of an event of default with respect to the subordinated debt securities arising from the failure to make payment.

The subordination provisions described above will not be applicable to payments in respect of the subordinated debt securities from a defeasance trust established in connection with any defeasance or covenant defeasance of the subordinated debt securities as described below under “Defeasance and Covenant Defeasance.”

The Subsidiary Guarantees

The payment obligations of Penn Virginia under any series of debt securities may be jointly and severally, fully and unconditionally guaranteed by any of the Subsidiary Guarantors. If a series of debt securities are so guaranteed, the Subsidiary Guarantors will execute a notation of guarantee as further evidence of their guarantee. The applicable prospectus supplement will describe the terms of any guarantee by the Subsidiary Guarantors.

The obligations of each Subsidiary Guarantor under its guarantee of the debt securities will be limited to the maximum amount that will not result in the obligations of the Subsidiary Guarantor under the guarantee constituting a fraudulent conveyance or fraudulent transfer under Federal or state law, after giving effect to:

• all other contingent and fixed liabilities of the Subsidiary Guarantor; and

• any collections from or payments made by or on behalf of any Subsidiary Guarantors in respect of the obligations of the Subsidiary Guarantor under its guarantee.

The guarantee of any Subsidiary Guarantor may be released under certain circumstances. If no default has occurred and is continuing under the applicable indenture, and to the extent not otherwise prohibited by the applicable indenture, a Subsidiary Guarantor will be unconditionally released and discharged from the guarantee:

• automatically upon any sale, exchange or transfer, to any person that is not an affiliate of Penn Virginia, of all of Penn Virginia’s direct or indirect limited liability company or other equity interests in the Subsidiary Guarantor;

• automatically upon the merger of the Subsidiary Guarantor into Penn Virginia or any other Subsidiary Guarantor or the liquidation and dissolution of the Subsidiary Guarantor; or

• following delivery of a written notice by us to the Trustee, upon the release of all guarantees by the Subsidiary Guarantor of any debt of Penn Virginia for borrowed money (or a guarantee of such debt), except for any series of debt securities.

Form, Exchange and Transfer

The debt securities of each series will be issuable only in fully registered form, without coupons. Unless otherwise indicated in the applicable prospectus supplement, the debt securities will be issued in denominations of $2,000 each or multiples of $1,000 in excess thereof.

At the option of the holder, subject to the terms of the applicable indenture and the limitations applicable to global securities, debt securities of each series will be exchangeable for other debt securities of the same series of any authorized denomination and of a like tenor and aggregate principal amount.

Subject to the terms of the applicable indenture and the limitations applicable to global securities, debt securities may be presented for exchange as provided above or for registration of transfer (duly endorsed or with

8

the form of transfer endorsed thereon duly executed) at the office of the security registrar or at the office of any transfer agent designated by us for that purpose. No service charge will be made for any registration of transfer or exchange of debt securities, but we may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. A transfer or an exchange will be effected upon the security registrar or the transfer agent, as the case maybe, being satisfied with the documents of title and identity of the person making the request. The security registrar and any other transfer agent initially designated by us for any debt securities will be named in the applicable prospectus supplement. We may at anytime designate additional transfer agents or rescind the designation of any transfer agent or approve a change in the office through which any transfer agent acts, except that we will be required to maintain a transfer agent in each place of payment for the debt securities of each series.

If the debt securities of any series (or of any series and specified tenor) are to be redeemed in part, we will not be required to:

• issue, register the transfer of or exchange any debt security of that series (or of that series and specified tenor, as the case maybe) during a period beginning at the opening of business 15 days before the day of mailing of a notice of redemption of any such debt security that may be selected for redemption and ending at the close of business on the day of such mailing; or

• register the transfer of or exchange any debt security so selected for redemption, in whole or in part, except the unredeemed portion of any such debt security being redeemed in part.

Global Securities

Some or all of the debt securities of any series maybe represented, in whole or in part, by one or more global certificates that will have an aggregate principal amount equal to that of the debt securities represented thereby. Each global security will be registered in the name of a depositary or a nominee thereof identified in the applicable prospectus supplement, will be deposited with such depositary or nominee or a custodian therefor and will bear a legend regarding the restrictions on exchanges and registration of transfer thereof referred to below and any such other matters as maybe provided for pursuant to the applicable indenture.

Notwithstanding any provision of the applicable indenture or any debt security described herein, no global security maybe exchanged in whole or in part for debt securities registered, and no transfer of a global security in whole or in part maybe registered, in the name of any person other than the depositary for such global security or any nominee of such depositary unless:

• the depositary has notified us that it is unwilling or unable to continue as depositary for such global security or has ceased to be qualified to act as such as required by the applicable indenture;

• there shall have occurred and be continuing an event of default with respect to the debt securities represented by such global security; or

• there shall exist such circumstances, if any, in addition to or in lieu of those described above as may be described in the applicable prospectus supplement.

All debt securities issued in exchange for a global security or any portion thereof will be registered in such names as the depositary may direct.

As long as the depositary, or its nominee, is the registered holder of a global security, the depositary or such nominee, as the case maybe, will be considered the sole owner and holder of the global security and the debt securities represented thereby for all purposes under the debt securities and the applicable indenture. Except in the limited circumstances referred to above, owners of beneficial interests in a global security will not be entitled to have that global security or any debt securities represented thereby registered in their names, will not receive or be entitled to receive physical delivery of certificated debt securities in exchange therefor and will not be considered to be the owners or holders of the global security or any debt securities represented thereby for any

9

purpose under the debt securities or the applicable indenture. All payments of principal of and any premium and interest on a global security will be made to the depositary or its nominee, as the case may be, as the holder thereof. The laws of some jurisdictions require that certain purchasers of debt securities take physical delivery of such debt securities in definitive form. These laws may impair the ability to transfer beneficial interests in a global security.

Ownership of beneficial interests in a global security will be limited to institutions that have accounts with the depositary or its nominee (“participants”) and to persons that may hold beneficial interests through participants. In connection with the issuance of any global security, the depositary will credit, on its book-entry registration and transfer system, the respective principal amounts of debt securities represented by the global security to the accounts of its participants. Ownership of beneficial interests in a global security will be shown only on, and the transfer of those ownership interests will be effected only through, records maintained by the depositary (with respect to participants’ interests) or any such participant (with respect to interests of persons held by such participants on their behalf). Payments, transfers, exchanges and other matters relating to beneficial interests in a global security maybe subject to various policies and procedures adopted by the depositary from time to time. None of us, the Trustees or our agents will have any responsibility or liability for any aspect of the depositary’s or any participant’s records relating to, or for payments made on account of, beneficial interests in a global security, or for maintaining, supervising or reviewing any records relating to such beneficial interests.

Payment and Paying Agents

Unless otherwise indicated in the applicable prospectus supplement, payment of interest on a debt security on any interest payment date will be made to the person in whose name such debt security (or one or more predecessor debt securities) is registered at the close of business on the regular record date for such interest.

Unless otherwise indicated in the applicable prospectus supplement, principal of and any premium and interest on the debt securities of a particular series will be payable at the office of such paying agent or paying agents as we may designate for such purpose from time to time, except that at our option payment of any interest maybe made by check mailed to the address of the Person entitled thereto as such address appears in the security register. Unless otherwise indicated in the applicable prospectus supplement, the corporate trust office of the trustee under the senior indenture in the City of New York will be designated as sole paying agent for payments with respect to senior debt securities of each series and the corporate trust office of the trustee in the City of New York will be designated as the sole paying agent for payment with respect to subordinated debt securities of each series. Any other paying agents initially designated by us for the debt securities of a particular series will be named in the applicable prospectus supplement. We may at any time designate additional paying agents or rescind the designation of any paying agent or approve a change in the office through which any paying agent acts, except that we will be required to maintain a paying agent in each place of payment for the debt securities of a particular series.

All moneys paid by us to a paying agent for the payment of the principal of or any premium or interest on any debt security that remain unclaimed at the end of two years after such principal, premium or interest has become due and payable will be repaid to us, and the holder of such debt security thereafter may look only to us for payment thereof.

Consolidation, Merger and Sale of Assets

We may not consolidate with or merge into, or convey, transfer, sell or lease our properties and assets substantially as an entirety to, any person (a “successor Person”), and may not permit any person to merge into, or convey, transfer, sell or lease its properties and assets substantially as an entirety to, us, unless:

• the successor person (if any) is a corporation, partnership, trust or other entity organized and validly existing under the laws of any domestic jurisdiction and assumes our obligations on the debt securities and under the indentures;

10

• immediately after giving effect to the transaction, no Event of Default, and no event that, after notice or lapse of time or both, would become an Event of Default, shall have occurred and be continuing; and

• certain other conditions, including any additional conditions with respect to any particular debt securities specified in the applicable prospectus supplement, are met. Reports

So long as any debt securities are outstanding, we will:

• file with the Trustee, within 15 days after we file them with the SEC, copies of the annual reports and of the information, documents and other reports which we are required to file with the SEC pursuant to the Exchange Act; and

• if we are not required to file information with the SEC pursuant to the Exchange Act, file with the Trustee, within 15 days after we would have been required to file with the SEC, and provide holders of the debt securities with, annual reports and information, documents and other reports comparable to what we would have been required to file with the SEC had we been subject to the reporting requirements of the Exchange Act.

Events of Default

Unless otherwise specified in the prospectus supplement, each of the following will constitute an “Event of Default” under the applicable indenture with respect to debt securities of any series:

• failure to pay principal of or any premium on any debt security of that series when due, whether or not, in the case of subordinated debt securities, such payment is prohibited by the subordination provisions of the subordinated indenture;

• failure to pay any interest on any debt securities of that series when due, continued for 30 days, whether or not, in the case of subordinated debt securities, such payment is prohibited by the subordination provisions of the subordinated indenture;

• failure to deposit any sinking fund payment when due in respect of any debt security of that series, whether or not, in the case of subordinated debt securities, such deposit is prohibited by the subordination provisions of the subordinated indenture;

• failure by the issuer or, if the series of debt securities is guaranteed by a Subsidiary Guarantor, the Subsidiary Guarantor, to perform, or a breach of, any of the other covenants or warranties in such indenture (other than a covenant or warranty included in such indenture solely for the benefit of a series other than that series), continued for 60 days after written notice has been given by the trustee, or the holders of at least 25% in principal amount of the outstanding debt securities of that series, as provided in such indenture;

• certain events of bankruptcy, insolvency or reorganization affecting us or, if the series of debt securities is guaranteed, the Subsidiary Guarantors;

• if the series of debt securities is guaranteed by any Subsidiary Guarantors:

• any of the guarantees ceases to be in full force and effect, except as otherwise provided in the Indenture;

• any of the guarantees is declared null and void in a judicial proceeding; or

• any Subsidiary Guarantor denies or disaffirms its obligations under the Indenture or its guarantee; and

• any other Event of Default included in the applicable indenture or supplemental indenture.

If an Event of Default (other than an Event of Default described in the fifth bullet above) with respect to the debt securities of any series at the time outstanding shall occur and be continuing, either the applicable Trustee or the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series by

11

notice as provided in the indenture may declare the principal amount of the debt securities of that series (or, in the case of any debt security that is an original issue discount debt security or the principal amount of which is not then determinable, such portion of the principal amount of such debt security, or such other amount in lieu of such principal amount, as maybe specified in the terms of such debt security) to be due and payable immediately. If an Event of Default described in the fifth bullet above with respect to the debt securities of any series at the time outstanding shall occur, the principal amount of all the debt securities of that series (or, in the case of any such original issue discount security or other debt security, such specified amount) will automatically, and without any action by the applicable Trustee or any holder, become immediately due and payable. After any such acceleration, but before a judgment or decree based on acceleration, the holders of a majority in aggregate principal amount of the outstanding debt securities of that series may, under certain circumstances, rescind and annul such acceleration if all Events of Default, other than the non-payment of accelerated principal (or other specified amount), have been cured or waived as provided in the applicable indenture. For information as to waiver of defaults, we refer you to “—Amendments and Waivers.”

Subject to the provisions of the indentures relating to the duties of the Trustees in case an Event of Default shall occur and be continuing, each Trustee will be under no obligation to exercise any of its rights or powers under the applicable indenture at the request or direction of any of the holders, unless such holders shall have offered to such Trustee reasonable indemnity. Subject to such provisions for the indemnification of the Trustees, the holders of a majority in aggregate principal amount of the outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to the debt securities of that series.

No holder of a debt security of any series will have any right to institute any proceeding with respect to the applicable indenture, or for the appointment of a receiver or a trustee, or for any other remedy thereunder, unless:

• such holder has previously given to the Trustee under the applicable indenture written notice of a continuing Event of Default with respect to the debt securities of that series;

• the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series have made written request, and such holder or holders have offered reasonable indemnity, to the Trustee to institute such proceeding as trustee; and

• the Trustee has failed to institute such proceeding, and has not received from the holders of a majority in aggregate principal amount of the outstanding debt securities of that series a direction inconsistent with such request, within 60 days after such notice, request and offer.

However, such limitations do not apply to a suit instituted by a holder of a debt security for the enforcement of payment of the principal of or any premium or interest on such debt security on or after the applicable due date specified in such debt security.

We will be required to furnish to each Trustee annually a statement by certain of our officers as to whether or not we, to our knowledge, are in default in the performance or observance of any of the terms, provisions and conditions of the applicable indenture and, if so, specifying all such known defaults.

Amendments and Waivers

We may amend the indentures without the consent of any holder of debt securities to:

• cure any ambiguity, defect or inconsistency;

• make any change in respect of any other series of debt securities issued under the indenture that is not applicable to such series;

• provide for the assumption by a successor of our obligations under the indenture;

12

• add Subsidiary Guarantors with respect to the debt securities;

• secure the debt securities;

• add covenants for the protection of the holders or surrender any right or power conferred upon us or any Subsidiary Guarantors;

• make any change that does not adversely affect the rights of any holder;

• add or appoint a successor or separate Trustee;

• comply with any requirements of the SEC in connection with the qualification of the indenture under the Trust Indenture Act; or

• establish the form or terms of debt securities of any series to be issued under the indenture.

In addition, we may amend the indenture if the holders of a majority in principal amount of all outstanding debt securities of each series that would be affected under the indenture consent to it. We may not, however, without the consent of each holder of any outstanding debt securities that would be affected, amend the indenture to:

• change the stated maturity of the principal of, or any installment of principal of or interest on, any debt security;

• reduce the principal amount of, or any premium or interest on, any debt security;

• reduce the amount of principal of an original issue discount security or any other debt security payable upon acceleration of the maturity thereof;

• change the place or currency of payment of principal of, or any premium or interest on, any debt security;

• impair the right to institute suit for the enforcement of any payment on or with respect to any debt security;

• in the case of subordinated debt securities, modify the subordination provisions in a manner adverse to the holders of the subordinated debt securities;

• if applicable, make any change that adversely affects the right to convert any debt security or decrease the conversion rate or increase the conversion price;

• reduce the percentage in principal amount of outstanding debt securities of any series, the consent of whose holders is required for modification or amendment of the indenture;

• reduce the percentage in principal amount of outstanding debt securities of any series necessary for waiver of compliance with certain provisions of the indenture or for waiver of certain defaults;

• modify such provisions with respect to modification and waiver;

• release a Subsidiary Guarantor or modify such Subsidiary Guarantor’s guarantee in any manner adverse to the holders; or

• following the making of an offer to purchase debt securities pursuant to a covenant in the indenture, modify the provisions of the indenture with respect to such offer to purchase in a manner adverse to the holders.

The holders of a majority in principal amount of the outstanding debt securities of any series may waive compliance by us or a Subsidiary Guarantor with certain restrictive provisions of the applicable indenture. The holders of a majority in principal amount of the outstanding debt securities of any series may waive any past default under the applicable indenture, except a default in the payment of principal, premium or interest and certain covenants and provisions of the applicable indenture that cannot be amended without the consent of the holder of each outstanding debt security of such series affected.

Defeasance and Covenant Defeasance

If and to the extent indicated in the applicable prospectus supplement, we may elect, at our option at any time, to have the provisions of the indenture, relating to defeasance and discharge of indebtedness relating to defeasance of certain restrictive covenants applied to the debt securities of any series, or to any specified part of a series.

Defeasance and Discharge. The indentures provide that, upon our exercise of our option (if any), we will be discharged from all our obligations, and, if such debt securities are subordinated debt securities, the provisions of the subordinated indenture relating to subordination will cease to be effective, with respect to such debt securities (except for certain obligations to exchange or register the transfer of debt securities, to replace stolen, lost or mutilated debt securities, to maintain paying agencies and to hold moneys for payment in trust) upon the deposit in trust for the benefit of the holders of such debt securities of money or U.S. Government obligations, or both, that, through the payment of principal and interest in respect thereof in accordance with their terms, will provide money in an amount sufficient to pay the principal of and any premium and interest on such debt securities on the respective stated maturities in accordance with the terms of the applicable indenture and such debt securities. Such defeasance or discharge may occur only if, among other things:

• we have delivered to the applicable Trustee an opinion of counsel to the effect that we have received from, or there has been published by, the United States Internal Revenue Service a ruling, or there has been a change in tax law, in either case to the effect that holders of such debt securities will not recognize gain or loss for federal income tax purposes as a result of such deposit, defeasance and discharge and will be subject to federal income tax on the same amount, in the same manner and at the same times as would have been the case if such deposit, defeasance and discharge were not to occur;

• no Event of Default or event that with the passing of time or the giving of notice, or both, shall constitute an Event of Default shall have occurred or be continuing;

• such deposit, defeasance and discharge will not result in a breach or violation of, or constitute a default under, any agreement or instrument to which we area party or by which we are bound; and

• in the case of subordinated debt securities, at the time of such deposit, no default in the payment of all or a portion of principal of (or premium, if any) or interest on or other obligations in respect of any senior debt of Penn Virginia shall have occurred and be continuing and no other Event of Default with respect to any of our Senior Debt shall have occurred and be continuing permitting, after notice or the lapse of time, or both, the acceleration thereof.

If we exercise this defeasance option, any guarantee will terminate with respect to that series of debt securities.

Defeasance of Certain Covenants. The indentures provide that, upon our exercise of our option (if any), we may omit to comply with certain restrictive covenants, including those that may be described in the applicable prospectus supplement, the occurrence of certain Events of Default, which are described above in the fourth bullet (with respect to such restrictive covenants), in the fifth bullet (with respect only to a Subsidiary Guarantor (if any)) and in the sixth bullet under “—Events of Default” and any that maybe described in the applicable prospectus supplement, will not be deemed to either be or result in an Event of Default and, if such debt securities are subordinated debt securities, the provisions of the subordinated indenture relating to subordination will cease to be effective, in each case with respect to such debt securities. In order to exercise such option, we must deposit, in trust for the benefit of the holders of such debt securities, money or U.S. Government obligations, or both, that, through the payment of principal and interest in respect thereof in accordance with their terms, will provide money in an amount sufficient to pay the principal of and any premium and interest on such debt securities on the respective stated maturities in accordance with the terms of the applicable indenture and such debt securities. Such covenant defeasance may occur only if we have delivered to the applicable Trustee an opinion of counsel that in effect says that holders of such debt securities will not recognize gain or loss for federal income tax purposes as a result of such deposit and defeasance of certain obligations and will be subject

14

to federal income tax on the same amount, in the same manner and at the same times as would have been the case if such deposit and defeasance were not to occur and the requirements set forth in the second through fourth bullets above are satisfied. If we exercise this option with respect to any debt securities and such debt securities were declared due and payable because of the occurrence of any Event of Default, the amount of money and U.S. Government obligations so deposited in trust would be sufficient to pay amounts due on such debt securities at the time of their respective stated maturities, but may not be sufficient to pay amounts due on such debt securities upon any acceleration resulting from such Event of Default. In such case, we would remain liable for such payments.

Notices

Notices to holders of debt securities will be given by mail to the addresses of such holders as they may appear in the security register.

Title

We, the Trustees and any agent of us or a Trustee may treat the person in whose name a debt security is registered as the absolute owner of the debt security (whether or not such debt security may be overdue) for the purpose of making payment and for all other purposes.

Governing Law

The indentures and the debt securities will be governed by, and construed in accordance with, the law of the State of New York.

DESCRIPTION OF CAPITAL STOCK

As of March 1, 2011, our authorized capital stock was 128,100,000 shares. Those shares consisted of 100,000 shares of preferred stock, par value $100.00 per share, none of which were outstanding, and 128,000,000 shares of common stock, par value $0.01 per share, of which 45,642,079 shares were outstanding.

Common Stock

Listing

Our outstanding shares of common stock are listed on the New York Stock Exchange (the “NYSE”) under the symbol “PVA.” Any additional common stock we issue also will be listed on the NYSE.

Dividends

Subject to the rights of any series of preferred stock that we may issue, the holders of common stock may receive dividends when declared by our board of directors. Dividends may be paid in cash, stock or other form out of legally available funds.

Fully Paid

All outstanding shares of common stock are fully paid and non-assessable. Any additional common stock we issue will also be fully paid and non-assessable.

Voting Rights

Subject to any special voting rights of any series of preferred stock that we may issue in the future, the holders of common stock may vote one vote for each share held in the election of directors and on all other matters voted upon by our shareholders. Directors are elected by a plurality of the votes cast by the shares entitled to vote. Holders of common stock may not cumulate their votes in the elections of directors. All other matters to be voted on by shareholders must be approved by a majority of the votes cast on the matter. Certain significant transactions defined in our articles of incorporation may also require the affirmative vote of 90% of the voting power of all outstanding shares entitled to vote in the election of directors. See “—Anti-Takeover Provisions—Certain Provisions in Our Articles of Incorporation—Fair Price Provisions” below.

Other Rights

We will notify common shareholders of any shareholders’ meetings according to applicable law. If we liquidate, dissolve or wind-up our business, either voluntarily or not, common shareholders will share equally in the assets remaining after we pay our creditors and preferred shareholders. The holders of common stock have no preemptive rights to purchase our shares of stock. Shares of common stock are not subject to any redemption or sinking fund provisions and are not convertible into any of our other securities.

Preferred Stock

The following description of the terms of the preferred stock sets forth certain general terms and provisions of our authorized preferred stock. If we offer preferred stock, a description will be filed with the SEC and the specific designations and rights will be described in the prospectus supplement, including the following terms:

• the series, the number of shares offered and the liquidation value of the preferred stock;

• the price at which the preferred stock will be issued;

• the dividend rate, the dates on which the dividends will be payable and other terms relating to the payment of dividends on the preferred stock;

16

• the liquidation preference of the preferred stock;

• the voting rights of the preferred stock;

• whether the preferred stock is redeemable or subject to a sinking fund, and the terms of any such redemption or sinking fund;

• whether the preferred stock is convertible or exchangeable for any other securities, and the terms of any such conversion; and

• any additional rights, preferences, qualifications, limitations and restrictions of the preferred stock.

The description of the terms of the preferred stock to be set forth in an applicable prospectus supplement will not be complete and will be subject to and qualified in its entirety by reference to the articles of amendment relating to the applicable series of preferred stock. The registration statement of which this prospectus forms a part will include the articles of amendment as an exhibit or incorporate it by reference.

Our board of directors can, without approval of shareholders, issue one or more series of preferred stock. Subject to the provisions of our articles of incorporation and limitations prescribed by law, our board of directors may adopt an amendment to our articles of incorporation describing the number of shares of each series and the rights, preferences and limitations of each series, including the dividend rights, voting rights, conversion rights, redemption rights and any liquidation preferences of any wholly unissued series of preferred stock, the number of shares constituting each series and the terms and conditions of issue.

Undesignated preferred stock may enable our board of directors to render more difficult or to discourage an attempt to obtain control of us by means of a tender offer, proxy contest, merger or otherwise, and to thereby protect the continuity of our management. The issuance of shares of preferred stock may adversely affect the rights of the holders of our common stock. For example, any preferred stock issued may rank prior to our common stock as to dividend rights, liquidation preference or both, may have full or limited voting rights and may be convertible into shares of common stock. As a result, the issuance of shares of preferred stock may discourage bids for our common stock or may otherwise adversely affect the market price of our common stock or any existing preferred stock.

The preferred stock will, when issued, be fully paid and non-assessable.

Anti-Takeover Provisions

Certain provisions in our articles of incorporation and by-laws, as well as certain provisions of Virginia law, may make more difficult or discourage a takeover of our business.

Certain Provisions of Our Articles of Incorporation

Shareholder Action by Unanimous Consent. Under Virginia law, any action that could be taken by shareholders at a meeting may be taken, instead, without a meeting and without notice if a consent in writing is signed by all the shareholders entitled to vote on the action.

Blank Check Preferred Stock. Our articles of incorporation authorize the issuance of blank check preferred stock. As described above under “Preferred Stock,” the board of directors can set the voting rights, redemption rights, conversion rights and other rights relating to such preferred stock and could issue such stock in either private or public transactions. In some circumstances, the blank check preferred stock could be issued and have the effect of preventing a merger, tender offer or other takeover attempt that the board of directors opposes.

Fair Price Provisions. Our articles of incorporation contain certain “fair price” provisions. These provisions state that any person who acquires 10% or more of our voting stock cannot engage in a significant transaction

17

with us that is not approved by our continuing directors or the holders of 90% of our stock unless our shareholders receive a price at least equal to that determined by a formula set forth in our articles of incorporation. In addition, if the acquiror paid cash to acquire his original interests, he must pay cash in the subsequent significant transaction. Under these provisions, continuing directors are directors who were on the board prior to the acquiror’s 10% or more acquisition or were subsequently recommended by such original directors.

Election and Removal of Directors

Our directors are elected for one-year terms and can be removed, with or without cause, if the number of votes cast for removal at a shareholder meeting called for that purpose constitutes a majority of the votes entitled to be cast at an election of directors. Our by-laws currently provide that the total number of directors is nine, but will automatically reduce to eight members effective on the date of our 2011 annual meeting of shareholders. The number of directors may be increased or decreased by amendment of the by-laws. Vacancies in the board maybe filled by shareholders or by the board. Special meetings of shareholders may be called only by a majority of our board of directors or by our chief executive officer. Our by-laws require that advance notice of nominees for election as directors be made by a shareholder, and that shareholder proposals be given to our corporate secretary, together with certain specified information, not less than 90 days nor more than 180 days before the anniversary of the immediately preceding annual meeting of shareholders.

Virginia Anti-Takeover Statutes and Other Virginia Laws

Control Share Acquisitions Statute. Under the Virginia control share acquisitions statute, shares acquired in an acquisition that would cause an acquiror’s voting strength to meet or exceed any of three thresholds (20%, 33 ¹/3% or 50%) have no voting rights unless (1) those rights are granted by a majority vote of all outstanding shares other than those held by the acquiror or any officer or employee director of the corporation or (2) the articles of incorporation or bylaws of the corporation provide that the provisions of the control share acquisitions statute do not apply to acquisitions of its shares. An acquiring person that owns five percent or more of the corporation’s voting stock may require that a special meeting of the shareholders be held, to consider the grant of voting rights to the shares acquired in the control share acquisition. This regulation was designed to deter certain takeovers of Virginia public corporations. As permitted by Virginia law, we have opted out of the Virginia anti-takeover law regulating “control share acquisitions.”

Affiliated Transactions. Under the Virginia anti-takeover law regulating affiliated transactions, material acquisition transactions between a Virginia corporation and any holder of more than 10% of any class of its outstanding voting shares are required to be approved by the holders of at least two-thirds of the remaining voting shares. Affiliated transactions subject to this approval requirement include mergers, share exchanges, material dispositions of corporate assets not in the ordinary course of business, any dissolution of the corporation proposed by or on behalf of a 10% holder or any reclassification, including reverse stock splits, recapitalization or merger of the corporation with its subsidiaries, that increases the percentage of voting shares owned beneficially by a 10% holder by more than five percent. For three years following the time that a shareholder becomes an interested shareholder, a Virginia corporation cannot engage in an affiliated transaction with the interested shareholder without approval of two-thirds of the disinterested voting shares and a majority of the disinterested directors. A disinterested director is a director who was a director on the date on which an interested shareholder became an interested shareholder or was recommended for election or elected by a majority of the disinterested directors then on the board. After three years, the approval of the disinterested directors is no longer required. The provisions of this statute do not apply if a majority of disinterested directors approve the acquisition of shares making a person an interested shareholder. Virginia law permits corporations to opt out of the affiliated transactions provisions. We have not opted out.

Director Standards of Conduct. Under Virginia law, directors must discharge their duties in accordance with their good faith business judgment of the best interests of the corporation. Directors may rely on the advice or

18

acts of others, including officers, employees, attorneys, accountants and board committees if they have a good faith belief in their competence. Virginia law provides that, in determining the best interests of the corporation, a director may consider the possibility that those interests may best be served by the continued independence of the corporation.

Indemnification of Officers and Directors

Virginia law permits, and our by-laws provide for, the indemnification of our directors and officers with respect to certain liabilities and expenses imposed upon them in connection with any civil, criminal or other proceeding by reason of having been a director or officer of Penn Virginia. This indemnification does not apply to willful misconduct or a knowing violation of the criminal law. We have been informed that in the opinion of the SEC indemnification for liability under the Securities Act is against public policy and is unenforceable.

Transfer Agent and Registrar

Our transfer agent and registrar of the common stock is American Stock Transfer & Trust Company.

DESCRIPTION OF DEPOSITARY SHARES

We may offer depositary shares (either separately or together with other securities) representing fractional interests in our preferred stock of any series. In connection with the issuance of any depositary shares, we will enter into a deposit agreement with a bank or trust company, as depositary, which will be named in the applicable prospectus supplement. Depositary shares will be evidenced by depositary receipts issued pursuant to the related deposit agreement. Immediately following our issuance of the preferred stock related to the depositary shares, we will deposit the preferred stock with the relevant preferred stock depositary and will cause the preferred stock depositary to issue, on our behalf, the related depositary receipts. Subject to the terms of the deposit agreement, each owner of a depositary receipt will be entitled, in proportion to the fraction of a share of preferred stock represented by the related depositary share, to all the rights, preferences and privileges of, and will be subject to all of the limitations and restrictions on, the preferred stock represented by the depositary receipt (including, if applicable, dividend, voting, conversion, exchange redemption and liquidation rights).

19

DESCRIPTION OF WARRANTS

We may issue warrants for the purchase of debt securities, preferred stock or common stock. Warrants maybe issued independently or together with, or as a unit including, debt securities, preferred stock or common stock offered by any prospectus supplement and maybe attached to or separate from any of the other offered securities. Each warrant will entitle the holder to purchase the principal amount of debt securities or number of shares of preferred stock or common stock, as the case may be, at the exercise price and in the manner specified in the prospectus supplement relating to those warrants. Warrants will be issued under one or more warrant agreements to be entered into between us and a bank or trust company, as warrant agent. The warrant agent will act solely as our agent in connection with the warrants and will not assume any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants. We will file the warrant agreement, and any unit agreement, with the SEC in connection with any offering of warrants.

The prospectus supplement relating to a particular issuance of warrants will describe the terms of the warrants, including the following:

• the title of the warrants;

• the offering price for the warrants, if any;

• the aggregate number of the warrants;

• the designation and terms of the securities purchasable upon exercise of the warrants;

• if applicable, the designation and terms of the securities with which the warrants are issued and the number of such warrants issued with each security;

• if applicable, the date from and after which the warrants and any securities issued with the warrants will be separately transferable;

• the date on which the right to exercise the warrants commences and the date on which the right expires;

• the antidilution provisions of the warrants, if any;
