As Representative of the several

Initial Purchasers listed in Schedule 1 hereto

Ladies and Gentlemen:

Penn Virginia Corporation, a Virginia corporation (the “Company”), proposes to issue and sell to the several Initial Purchasers listed in Schedule 1 hereto (the “Initial Purchasers”), for whom you are acting as representative (the “Representative”), $775,000,000 principal amount of its 8.500% Senior Notes due 2020 (the “Securities”). The Securities will be issued pursuant to an Indenture, dated as of June 15, 2009 (the “Base Indenture”), among the Company, the Guarantors (as defined below) and ▇▇▇▇▇ Fargo Bank, National Association, as trustee (the “Trustee”), as supplemented by the Fourth Supplemental Indenture thereto, to be dated as of the Closing Date (as defined below) (the “Fourth Supplemental Indenture” and the Base Indenture, as supplemented by the Fourth Supplemental Indenture, the “Indenture”), among the Company, the Guarantors and the Trustee. The Company’s obligations under the Securities, including the due and punctual payment of interest on the Securities, will be unconditionally guaranteed (the “Guarantees”) 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. (together the “Guarantors”). As used herein, the term “Securities” shall include the Guarantees, unless the context otherwise requires.

The Securities will be sold to the Initial Purchasers without being registered under the Securities Act of 1933, as amended (the “Securities Act”), in reliance upon an exemption therefrom. Holders of the Securities will be entitled to the benefits of a registration rights agreement, to be dated as of the Closing Date (the “Registration Rights Agreement”), among the Company, the Guarantors and the Initial Purchasers, pursuant to which the Company and the Guarantors may be required to file with the Securities and Exchange Commission (the “Commission”), under the circumstances set forth therein, (i) a registration statement under the Securities Act relating to a new series of debt securities for each series of Securities (the “Exchange Securities”) and the related guarantees of the Guarantors (the “Exchange

Guarantees”) with terms substantially identical to the Securities to be offered in exchange for the Securities (the “Exchange Offer”) and/or (ii) a shelf registration statement pursuant to Rule 415 of the Securities Act relating to the resale by certain holders of the Securities, and in each case, to use their reasonable best efforts to cause such registration statements to be declared effective. As used herein, the term “Exchange Securities” shall include the Exchange Guarantees, unless the context otherwise requires.

On April 2, 2013, the Company and Penn Virginia Oil & Gas Corporation (“Penn Virginia Oil”) entered into a stock purchase agreement (the “MHR SPA”) with Magnum Hunter Resources Corporation, a Delaware corporation (“MHR”), to acquire all of the issued and outstanding shares of common stock, no par value per share, of Eagle Ford Hunter, Inc., a Colorado corporation, from MHR (the “MHR Acquisition”).

On or prior to the Closing Date, the Representative, for itself and on behalf of the Initial Purchasers, will execute an escrow agreement, in the form and substance to be agreed between ▇▇▇▇▇ Fargo Bank, National Association, as escrow agent (the “Escrow Agent”), the Trustee and the Representative, which shall conform in all material respects with the description thereof included in the Offering Memorandum (as defined below) (the “Escrow Agreement”), and will direct the deposit in an escrow account (the “Escrow Account”) with the Escrow Agent, of the net proceeds from the sale of the Notes (before expenses but after initial purchaser discounts) under Section 2 hereof. The Escrow Agreement shall provide that the escrowed funds shall only be released and paid out pursuant to the terms of the Escrow Agreement.

The Company and the Guarantors hereby confirm their agreement with the several Initial Purchasers concerning the purchase and sale of the Securities, as follows:

1. Offering Documents. The Company has prepared a preliminary offering memorandum dated April 3, 2013 (the “Preliminary Offering Memorandum”) and a pricing term sheet substantially in the form attached hereto as Annex C (the “Pricing Term Sheet”) dated April 10, 2013, setting forth or including a description of the terms of the Securities, each for use by the Initial Purchasers in connection with the offering of the Securities. At or prior to the time, when sales of the Securities were first made, which was 4:20 p.m., New York City time on the date of this Agreement (the “Time of Sale”), the Company shall have prepared the following information (collectively, the “Time of Sale Information”): the Preliminary Offering Memorandum, as supplemented and amended by the document listed on Annex B hereto. If, subsequent to the date of this Agreement, the Company and the Initial Purchasers have determined that such Time of Sale Information included an untrue statement of a material fact or omitted a statement of material fact necessary to make the information therein, in the light of the circumstances under which it was made, not misleading and have agreed to provide an opportunity to purchasers of the Securities to terminate their old purchase contracts and enter into new purchase contracts, then “Time of Sale Information” will refer to the information available to purchasers at the time of entry into the first such new purchase contract. Promptly after the Time of Sale, the Company will prepare and deliver to each Initial Purchaser an offering memorandum (the “Offering Memorandum”), which will consist of the Preliminary Offering Memorandum with such changes therein as are required to reflect the information contained in the Pricing Term Sheet. All references herein to the Offering Memorandum shall be deemed to be a reference to both the Preliminary Offering Memorandum and the Offering Memorandum.

References herein to the Preliminary Offering Memorandum, the Time of Sale Information and the Offering Memorandum shall be deemed to refer to and include any document incorporated by reference therein. The terms “supplement,” “amendment” and “amend” as used herein with respect to the Preliminary Offering Memorandum, Time of Sale Information or the Offering Memorandum shall be deemed to refer to and include any documents filed by the Company under the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission thereunder (the “Exchange Act”) subsequent to the date of this Agreement which are incorporated by reference therein.

(g) The Company and the Guarantors acknowledge and agree that each Initial Purchaser is acting solely in the capacity of an arm’s length contractual counterparty to the Company and the Guarantors with respect to the offering of Securities contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an agent of, the Company, the Guarantors or any other person. Additionally, neither the Representative nor any other Initial Purchaser is advising the Company, the Guarantors or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction.

The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d) Contribution. If the indemnification provided for in paragraphs (a) and (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Guarantors on the one hand and the Initial Purchasers on the other from the offering of the Securities or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company and the Guarantors on the one hand and the Initial Purchasers on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Guarantors on the one hand and the Initial Purchasers on the other shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Company from the sale of the Securities and the total discounts and commissions received by the Initial Purchasers in connection therewith bear to the aggregate offering price of the Securities. The relative fault of the Company and the Guarantors on the one hand and the Initial Purchasers on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or any Guarantor or by the Initial Purchasers and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) Limitation on Liability. The Company, the Guarantors and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 7, in no event shall an Initial Purchaser be required to contribute any amount in excess of the amount by which the total discounts and commissions received by such Initial Purchaser with respect to the offering of the Securities exceeds the amount of any damages that such Initial Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Initial Purchasers’ obligations to contribute pursuant to this Section 7 are several in proportion to their respective purchase obligations hereunder and not joint.

(f) Non-Exclusive Remedies. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity.

8. Effectiveness of Agreement. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

9. Termination. This Agreement may be terminated in the absolute discretion of the Representative, by notice to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on or by any of the New York Stock Exchange or over-the-counter market, the American Stock Exchange, the Financial Industry Regulatory Authority, the Chicago Board Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade; (ii) trading of any securities issued or guaranteed by the Company or any of the Guarantors shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by federal or New York State authorities; (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or general economic or political conditions including, without limitation, as a result of terrorist activities or any calamity or crisis, either within or outside the United States, that, in the judgment of the Representative, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities on the Closing Date on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Offering Memorandum; or (v) the representation in Section 3(b) is incorrect in any respect.

10. Defaulting Initial Purchaser.

(a) If, on the Closing Date any Initial Purchaser defaults on its obligation to purchase the Securities that it has agreed to purchase hereunder, the non-defaulting Initial Purchasers may in their discretion arrange for the purchase of such Securities by other persons satisfactory to the Company on the terms contained in this Agreement. If, within 36 hours after any such default by any Initial Purchaser, the non-defaulting Initial Purchasers do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Initial Purchasers to purchase such Securities on such terms. If other persons become obligated or agree to purchase the Securities of a defaulting Initial Purchaser, either the non-defaulting Initial Purchasers or the Company may postpone the Closing Date for up to five full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Initial Purchasers may be necessary in the Time of Sale Information and the Offering Memorandum or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Time of Sale Information and the Offering Memorandum that effects any such changes. As used in this Agreement, the term “Initial Purchaser” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 10, purchases Securities that a defaulting Initial Purchaser agreed but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Initial Purchaser or Initial Purchasers by the non-defaulting Initial Purchasers and the Company as provided in paragraph (a) above, the aggregate principal amount of Securities that remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Securities, then the Company shall have the right to require each non-defaulting Initial Purchaser to purchase the principal amount of Securities that such Initial Purchaser agreed to purchase hereunder (or under any other agreement pursuant to which such Initial Purchaser agreed to purchase Securities that a defaulting Initial Purchaser failed to purchase) plus such Initial Purchaser’s pro rata share (based on the aggregate principal amount of Securities that such Initial Purchaser agreed to purchase hereunder) of the Securities of such defaulting Initial Purchaser or Initial Purchasers for which such arrangements have not been made.

(c) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Initial Purchaser or Initial Purchasers by the non-defaulting Initial Purchasers and the Company as provided in paragraph (a) above, the aggregate principal amount of Securities that remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Securities, or if the Company shall not exercise the right described in paragraph (b) above, then this Agreement shall terminate without liability on the part of the non-defaulting Initial Purchasers. Any termination of this Agreement pursuant to this Section 10 shall be without liability on the part of the Company, except that the Company will continue to be liable for the payment of expenses as set forth in Section 11 hereof and except that the provisions of Section 7 hereof shall not terminate and shall remain in effect.

(d) Nothing contained herein shall relieve a defaulting Initial Purchaser of any liability it may have to the Company or any non-defaulting Initial Purchaser for damages caused by its default, including expenses paid pursuant to Section 11(b) below.

11. Payment of Expenses.

(a) Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Company and the Guarantors jointly and severally will pay or cause to be paid all costs and expenses incident to the performance of its obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the Securities and any taxes payable in that connection; (ii) the costs incident to the preparation and printing of the Preliminary Offering Memorandum, any Time of Sale Information and the Offering Memorandum (including all exhibits, amendments and supplements thereto) and the distribution thereof; (iii) the fees and expenses of the Company’s and the Guarantors’ counsel and independent accountants; (iv) the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Securities under the laws of Canada and such other jurisdictions as the Representative may designate and the preparation, printing and distribution of a Blue Sky Memorandum (including the related fees and expenses of counsel for the Initial Purchasers); (v) any fees charged by rating agencies for rating the Securities; (vi) the fees and expenses of the Trustee and any paying agent (including related fees and expenses of any counsel to such parties); (vii) the preparation, printing and distribution of one or more versions of the Preliminary Offering Memorandum and the Offering Memorandum for distribution in Canada, often in the form of a Canadian “wrapper” (including related fees and expenses of Canadian counsel to the Initial Purchasers; (viii) all expenses incurred by the Company in connection with any “road show” presentation to potential investors; and (ix) the fees and expenses of the Escrow Agent, including the fees and disbursement of counsel for the Escrow Agent in connection with the Escrow Agreement.

(b) If (i) this Agreement is terminated pursuant to Sections 9(ii) or 9(v), (ii) the Company for any reason fails to tender the Securities for delivery to the Initial Purchasers by reason of any failure, refusal or inability on the part of the Company to perform any of the obligations under this Agreement or (iii) the Initial Purchasers decline to purchase the Securities for any reason permitted under this Agreement, the Company and each of the Guarantors jointly and severally agree to reimburse the Initial Purchasers for all out-of-pocket costs and expenses (including the fees and expenses of their counsel) reasonably incurred by the Initial Purchasers in connection with this Agreement and the offering contemplated hereby; provided that the Company shall not be obligated to reimburse such costs and expenses of the Initial Purchasers if this Agreement is terminated pursuant to Sections 9(i), 9(iii) or 9(iv), and the Company shall not be obligated to reimburse such costs and expenses of a defaulting Initial Purchaser if this Agreement is terminated pursuant to Section 10 by reason of the default of an Initial ▇▇▇▇▇▇▇▇▇.

The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the Initial Purchasers with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Company by such Initial Purchasers’ investment banking divisions. The Company acknowledges that each of the Initial Purchasers is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the companies that may be the subject of the transactions contemplated by this Agreement.

1. Each of Penn Virginia Holding Corp., Penn Virginia MC Corporation, Penn Virginia MC Energy L.L.C., Penn Virginia MC Operating Company L.L.C., Penn Virginia Oil & Gas GP LLC and Penn Virginia Oil & Gas LP LLC (the “Delaware Guarantors”) has been duly incorporated or formed and is validly existing and in good standing under the laws of the State of Delaware and has the requisite corporate or limited liability company power and authority, as applicable, necessary to own or hold its properties and to conduct the businesses in which it is engaged as described in the Time of Sale Information and the Offering Memorandum, except where the failure to have such power or authority would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

2. Penn Virginia Oil & Gas, L.P. (the “Texas Guarantor” and, together with the Delaware Guarantors, the “Applicable Guarantors”) has been duly formed and is validly existing and in good standing under the laws of the State of Texas and has the requisite limited partnership power and authority necessary to own or hold its properties and to conduct the businesses in which it is engaged as described in the Time of Sale Information and the Offering Memorandum, except where the failure to have such power or authority would not, individually or in the aggregate, be reasonably expected to have a Material Adverse Effect.

3. Each Applicable Guarantor has the requisite corporate, limited liability company or limited partnership power and authority, as applicable, to enter into the Agreement, the Registration Rights Agreement, the Indenture, the Guarantees and the Exchange Guarantees and to perform its obligations thereunder.

4. The Agreement, the Registration Rights Agreement, the Indenture, the Guarantees and the Exchange Guarantees have each been duly authorized by each Applicable Guarantor and, except for the Guarantees and the Exchange Guarantees, have been duly executed and delivered.

5. Assuming that, under the laws of the Commonwealth of Virginia, each of the Base Indenture and the Fourth Supplemental Indenture has been duly authorized, executed and delivered by the Company and Penn Virginia Oil & Gas Corporation (the “Virginia Guarantor”) and, assuming due authorization, execution and delivery thereof by the Trustee, the Indenture constitutes a valid and legally binding agreement of the Company and the Guarantors enforceable against the Company and the Guarantors in accordance with its terms, subject to the Enforceability Exceptions.

6. Assuming that, under the laws of the Commonwealth of Virginia, the Registration Rights Agreement has been duly authorized, executed and delivered by the Company and the Virginia Guarantor and, assuming due authorization, execution and delivery thereof by the other parties thereto, the Registration Rights Agreement constitutes a valid and legally binding agreement of the Company and the Guarantors enforceable against the Company and the Guarantors in accordance with its terms, subject to the Enforceability Exceptions.

A-1-1

7. Assuming that, under the laws of the Commonwealth of Virginia, the Securities have been duly authorized, executed and delivered by the Company, when duly authenticated as provided in the Indenture and paid for as provided in the Agreement, the Securities will constitute valid and legally binding obligations of the Company enforceable against the Company in accordance with their terms, subject to the Enforceability Exceptions, and will be entitled to the benefits of the Indenture.

8. Assuming that, under the laws of the Commonwealth of Virginia, the Exchange Securities have been duly authorized, executed and delivered by the Company, when duly authenticated as provided in the Indenture and issued in exchange for the Securities pursuant to the Registration Rights Agreement, the Exchange Securities will constitute valid and legally binding obligations of the Company, enforceable against the Company in accordance with their terms, subject to the Enforceability Exceptions, and will be entitled to the benefits of the Indenture.

9. Assuming that, under the laws of the Commonwealth of Virginia, the Guarantee of the Virginia Guarantor has been duly authorized by the Virginia Guarantor, when the Securities have been validly issued, executed and authenticated in accordance with the terms of the Indenture and paid for as provided therein, the Guarantees will constitute valid and legally binding obligations of the Guarantors in accordance with their terms, subject to the Enforceability Exceptions.

10. All the outstanding shares of capital stock or other equity interests of each Applicable Guarantor have been duly and validly authorized and issued, and are fully paid (to the extent required under such Applicable Guarantor’s organizational documents) and non-assessable, except as such non-assessability may be affected by Sections 18-607 and 18-804 of the Delaware LLC Act and Sections 153.102 and 153.210 of the Texas Business Organizations Code, as applicable.

11. The execution, delivery and performance by the Company and each Guarantor of each of the Transaction Documents, the issuance and sale of the Securities on the Closing Date and compliance by the Company and each Guarantor with the terms thereof and the consummation of the transactions contemplated by the Transaction Documents will not (i) result in a breach or violation of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company or any of its subsidiaries pursuant to, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which the Company or any of its subsidiaries is a party or by which the Company or any of its subsidiaries is bound or to which any of the property or assets of the Company or any of its subsidiaries is subject, that is filed or incorporated by reference as an exhibit to (x) the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 and (y) each current or periodic report filed by the Company with the United States Securities and Exchange Commission from the date of filing of such Annual Report to the date hereof, or (ii) result in the violation of any U.S. federal or New York State law or statute or any judgment, order or regulation of any U.S. federal or New York State court or arbitrator or governmental or regulatory authority (excluding U.S. federal or New York State securities laws or statutes or any judgment, order or regulation thereunder), except, in the case of clauses (i) and (ii) above, for such breach or violation that would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

A-3-2

12. No consent, approval, authorization, order, registration or qualification of or with any U.S. federal or New York State court or arbitrator or governmental or regulatory authority is required for the execution, delivery and performance by the Company and the Guarantors of the Transaction Documents, the issuance and sale of the Securities and compliance by the Company and each Guarantor with the terms thereof, and the consummation of the transactions contemplated by the Transaction Documents, except for such consents, approvals, authorizations, orders and registrations or qualifications as may be required under applicable state securities laws in connection with the purchase and distribution of the Securities by the Initial Purchasers. We express no opinion in this paragraph 12 as to the matters addressed in paragraph 16 below.

13. The statements in the Time of Sale Information and the Offering Memorandum under the headings “Certain U.S. Federal Income and Estate Tax Considerations” and “Description of Notes,” to the extent that they constitute summaries of the terms of the Securities, matters of law or regulation or legal conclusions, are accurate in all material respects.

14. Neither the Company nor any Guarantor is and, after giving effect to the offering and sale of the Securities and the application of the proceeds thereof as described in the Time of Sale Information and the Offering Memorandum, will not be required to register as an “investment company” within the meaning of the Investment Company Act.

15. The Indenture meets the requirements for qualification under the Trust Indenture Act, and the rules and regulations of the Commission applicable to an indenture which is qualified thereunder.

16. No registration of the Notes or the Guarantees under the Securities Act, and no qualification of the Indenture under the Trust Indenture Act is required for the purchase of the Notes by you or the initial resale of the Notes by you, in each case, in the manner contemplated by the Agreement, the Time of Sale Information and the Offering Memorandum. We express no opinion, however, as to when or under what circumstances any Notes initially sold by you may be reoffered or resold.

Such counsel shall also state that they have participated in conferences with representatives of the Company, with representatives of its independent accountants and counsel and representatives of the Initial Purchasers and their counsel, at which conferences the contents of Preliminary Offering Memorandum, the Time of Sale Information and the Offering Memorandum and any amendment and supplement thereto and related matters were discussed and, although such counsel assume no responsibility for the accuracy, completeness or fairness of the Preliminary Offering Memorandum, the Time of Sale Information and the Offering Memorandum and any amendment or supplement thereto (except as expressly provided in paragraph 13 above), nothing has come to the attention of such counsel to cause such counsel to believe that the Time of Sale Information, at the Time of Sale, contained any untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading or that the Offering Memorandum or any amendment or supplement thereto as of its date and the Closing Date

A-3-3

contained or contains any untrue statement of a material fact or omitted or omits to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading (other than the financial statements and related schedules and notes thereto and other financial, accounting and oil or natural gas reserve information contained or incorporated by reference therein or omitted therefrom, as to which such counsel need express no belief).

In rendering such opinion, such counsel may rely as to matters of fact on certificates of responsible officers of the Company and public officials that are furnished to the Initial Purchasers.

Annex C-3



Use of Proceeds		Approximately $400 million of the net proceeds will be used to partially finance the Acquisition (including expected purchase price adjustments). Approximately $330 million of the net proceeds will be used to fund PVA’s obligations under its anticipated tender offer (the “Tender Offer”) for all of its outstanding 10.375 percent senior notes due 2016 (the “2016 Senior Notes”), and the remaining net proceeds will be used to repay outstanding borrowings under PVA’s Revolver. If the Acquisition does not close by June 30, 2013, the notes will be redeemed at 100% of their initial offering price. To the extent less than all of the outstanding 2016 Senior Notes are tendered in the anticipated Tender Offer or the Tender Offer is not consummated, PVA intends to use the remaining portion of the net proceeds intended to be used to fund the Tender Offer to redeem any or all of the 2016 Senior Notes remaining outstanding in June 2013. Pending closing of the Acquisition, the net proceeds of this offering will be escrowed as described below opposite “Escrow; Special Mandatory Redemption.”

If (i) the Acquisition has not been consummated by 5:00 p.m., Central Time, on June 30, 2013 or (ii) the stock purchase agreement relating to the Acquisition is terminated prior to the consummation of the Acquisition, then the funds in the escrow account, together with additional funds PVA will provide, will be used to redeem all of the notes at a redemption price (the “Redemption Price”) equal 100% of their initial offering price, plus accrued and unpaid interest from the date of initial issuance to, but not including, the date of redemption. All of the escrowed funds will be released to PVA in connection with the simultaneous consummation of the Acquisition.

Settlement Date		April 24, 2013 (T+10) 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 notes on the date of pricing or the six succeeding business days will be required, by virtue of the fact that the notes initially will settle T+10, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of notes who wish to trade notes on the date of pricing or the next six succeeding business days should consult their own advisor.

Annex C-6

(1)

As of March 31, 2013, we had cash and cash equivalents of $10.7 million. Subsequently, in connection with entering into the stock purchase agreement relating to the Acquisition, we borrowed $5 million under our Revolver and paid a deposit of $10 million to MHR, which will be applied towards the purchase price at the closing of the Acquisition. The amount presented does not give effect to the payment of approximately $11.7 million of accrued but unpaid interest expense on the 2016 Senior Notes, which we expect to fund with a portion of the net proceeds from this offering.

(2)

As of March 31, 2013, we had $38.0 million of borrowings outstanding under our Revolver. See “Description of Other Indebtedness—Our Revolver.” After giving effect to the Acquisition, the issuance and sale of the notes and the application of the net proceeds therefrom, as of December 31, 2012, we would have had $274.1 million of remaining borrowing capacity under our Revolver, net of $2.1 million in letters of credit outstanding. See “Description of Other Indebtedness—Our Revolver.”

(3)

Assumes all outstanding 2016 Senior Notes are properly tendered and not validly withdrawn in accordance with the terms of the anticipated Tender Offer. To the extent less than all of the outstanding 2016 Senior Notes are repurchased in the anticipated Tender Offer or the anticipated Tender Offer is not consummated, PVA intends redeem any or all of the 2016 Senior Notes remaining outstanding. Beginning in June 2013, PVA may redeem all or part of the 2016 Senior Notes at a redemption price beginning at 105.188% of the principal amount.

(4)

Assumes the notes will be issued at par. If (i) the Acquisition has not been consummated by 5:00 p.m., Central Time, on June 30, 2013 or (ii) the stock purchase agreement relating to the Acquisition is terminated prior to the consummation of the Acquisition, we will be required to redeem all of the notes then outstanding at 100% of their initial offering price, plus accrued and unpaid interest from the date of initial issuance to, but not including, the date of redemption.

(5)

Represents 11,500 shares of our 6% Series A Convertible Perpetual Preferred Stock, or our 6% Preferred Stock, at $100 par value per share.

Other Pro Forma Financial Information:

On a pro forma basis, after giving effect to the issuance and sale of the notes in this offering and the application of the net proceeds therefrom, the Acquisition, the issuance of 10 million shares of our common stock to MHR with an aggregate value of $40 million and the anticipated Tender Offer, PVA’s loss on extinguishment of debt would have been approximately $34.5 million, deficiency of earnings to fixed charges and preferred stock dividends would have been approximately $268.9 million, EBITDAX would have been approximately $163.3 million and Adjusted EBITDAX would have been approximately $309.4 million, in each case, for the year ended December 31, 2012.
