(g) At the time of execution of this Agreement, the Underwriter shall have received from KPMG LLP one or more letters, in form and substance satisfactory to the Underwriter, addressed to the Underwriter and dated the date hereof (i) confirming that they are independent public accountants within the meaning of the Securities Act and are in compliance with the applicable requirements relating to the qualification of accountants under Rule 2-01 of Regulation S-X of the Commission, and (ii) stating, as of the date hereof (or, with respect to matters involving changes or developments since the respective dates as of which specified financial information is given in the most recent Preliminary Prospectus, as of a date not more than three days prior to the date hereof), the conclusions and findings of such firm with respect to the financial information and other matters ordinarily covered by accountants’ “comfort letters” to underwriters in connection with registered public offerings.

(h) With respect to the letter(s) of KPMG LLP referred to in the preceding paragraph and delivered to the Underwriter concurrently with the execution of this Agreement (the “initial letters”), the Partnership shall have furnished to the Underwriter one or more letters (the “bring-down letters”) of such accountants, addressed to the Underwriter and dated the Delivery Date (i) confirming that they are independent public accountants within the meaning of the Securities Act and are in compliance with the applicable requirements relating to the qualification of accountants under Rule 2-01 of Regulation S-X of the Commission, (ii) stating, as of the date of the bring-down letters (or, with respect to matters involving changes or developments since the respective dates as of which specified financial information is given

(i) The Partnership shall have furnished to the Underwriter a certificate, dated the Delivery Date, signed on behalf of the Partnership by (i) the Chief Executive Officer of the General Partner and (ii) the Chief Financial Officer of the General Partner, stating that:

(ii) no stop order suspending the effectiveness of the Registration Statement has been issued; and no proceedings or examination for that purpose have been instituted or, to their knowledge, threatened; and

(j) Each Selling Unitholder shall have furnished to the Underwriter on the Delivery Date a certificate, dated the Delivery Date, signed by, or on behalf of, such Selling Unitholder stating that the representations, warranties and agreements of such Selling Unitholder contained herein are true and correct on and as of the Delivery Date and that such Selling Unitholder has complied with all its agreements contained herein and has satisfied all the conditions on its part to be performed or satisfied hereunder at or prior to the Delivery Date.

(k) Except as described in the most recent Preliminary Prospectus, (i) none of the Partnership Entities shall have sustained since the date of the latest audited financial statements included in the most recent Preliminary Prospectus any loss or interference with its business from fire, flood, explosion or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree; (ii) nor shall there have been a change in the partners’ capital, members’ interest, or long-term debt of any of the Partnership Entities or change, or any development involving a prospective change, in or affecting the condition (financial or otherwise), results of operations, properties, management, business or prospects of the Partnership Entities taken as a whole, the effect of which, in any

such case described in clause (i) or (ii), in the judgment of the Underwriter is so material and adverse as to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Units being delivered on the Delivery Date on the terms and in the manner contemplated in the Prospectus.

(l) Subsequent to the execution and delivery of this Agreement there shall not have occurred any of the following: (i) trading in securities generally on the NYSE, the American Stock Exchange or the Nasdaq Global Market or in the over-the-counter market, or trading in any securities of the Partnership on any exchange or in the over-the-counter market, shall have been suspended or materially limited or the settlement of such trading generally shall have been materially disrupted or minimum prices shall have been established on any such exchange or such market by the Commission, by such exchange or by any other regulatory body or governmental authority having jurisdiction, (ii) a banking moratorium shall have been declared by federal or state authorities, (iii) the United States shall have become engaged in hostilities, there shall have been an escalation in hostilities involving the United States or there shall have been a declaration of a national emergency or war by the United States or (iv) there shall have occurred such a material adverse change in general economic, political or financial conditions, including, without limitation, as a result of terrorist activities after the date hereof (or the effect of international conditions on the financial markets in the United States shall be such) as to make it, in the judgment of the Underwriter, impracticable or inadvisable to proceed with the public offering or delivery of the Units being delivered on the Delivery Date on the terms and in the manner contemplated in the Prospectus.

(m) The NYSE shall have approved the Units for listing.

(n) The Lock-Up Agreements between the Underwriter and each person or entity set forth on Schedule 5, delivered to the Underwriter on or before the date of this Agreement, shall be in full force and effect on the Delivery Date.

10. Indemnification and Contribution.

(a) Each of the Partnership Parties, jointly and severally, shall indemnify and hold harmless the Underwriter, its directors, officers and employees and each person, if any, who controls the Underwriter within the meaning of Section 15 of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of the Units), to which that Underwriter, director, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in (A) any Preliminary Prospectus, the

Registration Statement, the Prospectus or in any amendment or supplement thereto, (B) any Issuer Free Writing Prospectus or in any amendment or supplement thereto or (C) any Permitted Issuer Information used or referred to in any “free writing prospectus” (as defined in Rule 405 of the Rules and Regulations) used or referred to by the Underwriter or (ii) (A) the omission or alleged omission to state in any the Registration Statement or in any amendment or supplement thereto any material fact required to be stated therein or necessary to make the statements therein not misleading or (B) the omission or alleged omission to state in any Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Permitted Issuer Information, any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, and shall reimburse the Underwriter and each such director, officer, employee or controlling person promptly upon demand for any legal or other expenses reasonably incurred by that Underwriter, director, officer, employee or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Partnership Parties shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any such amendment or supplement thereto or in any Permitted Issuer Information, in reliance upon and in conformity with (A) written information concerning the Underwriter furnished to the Partnership Parties by or on behalf of the Underwriter specifically for inclusion therein, which information consists solely of the information specified in Section 10(f) or (B) written information concerning any Selling Unitholder furnished to the Partnership by such Selling Unitholder specifically for inclusion therein, which information consists solely of the information appearing in the Prospectus under the caption “Selling Unitholders.” The foregoing indemnity agreement is in addition to any liability that the Partnership Parties may otherwise have to the Underwriter or to any director, officer, employee or controlling person of the Underwriter.

(b) Each Selling Unitholder, jointly and severally, shall indemnify and hold harmless the Underwriter and the Partnership Parties, their directors, officers and employees and each person, if any, who controls the Underwriter or the Partnership Parties within the meaning of Section 15 of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of the Units), to which the Underwriter, the Partnership Parties, their directors, officers, employees or controlling persons may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in (A) any Preliminary Prospectus, the Registration Statement, the Prospectus or in any amendment or supplement thereto, (B) any Permitted Issuer Information or any “free writing prospectus” (as defined in Rule 405 of the Rules and Regulations), prepared by or on behalf of any Selling Unitholder or used or referred to by the Selling Unitholders in connection with the offering of the Units in violation of Section 7(a) (a “Selling Unitholder Free Writing Prospectus”) or (C) any Issuer Free Writing Prospectus or in any amendment or supplement thereto or (ii) (A) the omission or alleged omission to state in the Registration Statement or in any amendment or supplement

thereto any material fact required to be stated therein or necessary to make the statements therein not misleading or (B) the omission or alleged omission to state in any Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Permitted Issuer Information or any Selling Unitholder Free Writing Prospectus, any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, and shall reimburse the Underwriter, each Partnership Party and each such director, officer, employee or controlling person promptly upon demand for any legal or other expenses reasonably incurred by that Underwriter, Partnership Party, director, officer, employee or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that such Selling Unitholder shall be liable in any such case only to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or any such amendment or supplement or in any Permitted Issuer Information in reliance upon and in conformity with written information concerning such Selling Unitholder furnished to the Partnership by such Selling Unitholder specifically for inclusion therein, which information is limited to the information set forth in the Prospectus under the caption “Selling Unitholders,” or arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in any Selling Unitholder Free Writing Prospectus. The liability of each of the Selling Unitholders under the indemnity agreement contained in this paragraph shall be limited to an amount equal to the total net proceeds from the offering of the Units purchased under the Agreement received by each such Selling Unitholder. The foregoing indemnity agreement is in addition to any liability that any Selling Unitholders may otherwise have to the Underwriter, any Partnership Party or any officer, employee or controlling person of the Underwriter or any Partnership Party.

(c) The Underwriter shall indemnify and hold harmless each of the Partnership Parties and the Selling Unitholders, their respective directors, managers, officers and employees, and each person, if any, who controls any of the Partnership Parties or the Selling Unitholders within the meaning of Section 15 of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Partnership Parties, the Selling Unitholders or any such director, manager, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto, or (ii) (A) the omission or alleged omission to state in the Registration Statement or in any amendment or supplement thereto any material fact required to be stated therein or necessary to make the statements therein not misleading or (B) the omission or alleged omission to state in any Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto, any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information concerning the Underwriter furnished to the Partnership

by or on behalf of the Underwriter specifically for inclusion therein, which information is limited to the information set forth in Section 10(f). The foregoing indemnity agreement is in addition to any liability that the Underwriter may otherwise have to the Partnership Parties, the Selling Unitholders or any such director, manager, officer, employee or controlling person.

(d) Promptly after receipt by an indemnified party under this Section 10 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 10, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 10 except to the extent it has been materially prejudiced by such failure and, provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 10. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 10 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the indemnified party shall have the right to employ counsel to represent jointly the indemnified party and those other indemnified parties and their respective directors, officers, employees and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought under this Section 10 if (i) the indemnified party and the indemnifying party shall have so mutually agreed; (ii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party; (iii) the indemnified party and its directors, officers, employees and controlling persons shall have reasonably concluded that there may be legal defenses available to them that are different from or in addition to those available to the indemnifying party; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the indemnified parties or their respective directors, officers, employees or controlling persons, on the one hand, and the indemnifying party, on the other hand, and representation of both sets of parties by the same counsel would be inappropriate due to actual or potential differing interests between them, and in any such event the fees and expenses of such separate counsel shall be paid by the indemnifying party. No indemnifying party shall (i) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld), settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and does not include any findings of fact or admissions of fault or culpability as to the indemnified party, or (ii) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment for the plaintiff in any such action, the

indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment.

(e) If the indemnification provided for in this Section 10 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 10(a), 10(b) or 10(c) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Selling Unitholders, on the one hand, and the Underwriter, on the other, from the offering of the Units or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Partnership Parties and the Selling Unitholders, on the one hand, and the Underwriter, on the other, with respect to the statements or omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Selling Unitholders, on the one hand, and the Underwriter, on the other, with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Units purchased under this Agreement (before deducting expenses) received by the Selling Unitholders, as set forth in the table on the cover page of the Prospectus, on the one hand, and the total underwriting discounts and commissions received by the Underwriter with respect to the Units purchased under this Agreement, as set forth in the table on the cover page of the Prospectus, on the other hand. The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Partnership Parties, the Selling Unitholders or the Underwriter, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Partnership Parties, the Selling Unitholders and the Underwriter agree that it would not be just and equitable if contributions pursuant to this Section 10(e) were to be determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 10(e) shall be deemed to include, for purposes of this Section 10(e), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 10(e), the Underwriter shall not be required to contribute any amount in excess of the amount by which the gross proceeds from the sale of the Units underwritten by it exceeds the amount of any damages that the Underwriter has otherwise paid or become liable to pay by reason of any 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.

(f) The Underwriter confirms and the Partnership Parties and the Selling Unitholders acknowledge that the statements regarding the delivery of the Units by the Underwriter set forth on the cover page of the Prospectus and the concession figure in the

fourth paragraph and the statements in the eleventh and twelfth paragraphs dealing with stabilization or related activities appearing under the caption “Underwriting” in the most recent Preliminary Prospectus and the Prospectus are correct and constitute the only information concerning the Underwriter furnished in writing to the Partnership by or on behalf of the Underwriter specifically for inclusion in any Preliminary Prospectus, Registration Statement, the Prospectus any Issuer Free Writing Prospectus or in any amendment or supplement thereto.

11. [Reserved.]

12. Termination. The obligations of the Underwriter hereunder may be terminated by the Underwriter by notice given to and received by the Partnership prior to delivery of and payment for the Units if, prior to that time, any of the events described in Sections 9(k) or 9(l) shall have occurred or if the Underwriter shall decline to purchase the Units for any reason permitted under this Agreement.

13. Reimbursement of Underwriter’s Expenses. If any Selling Unitholder shall fail to tender the Units for delivery to the Underwriter by reason of (i) any failure, refusal or inability on the part of such Selling Unitholder to perform any agreement on its part to be performed, or because any other condition of the Underwriter’s obligations hereunder required to be fulfilled by such Selling Unitholder is not fulfilled for any reason, the Selling Unitholders will reimburse the Underwriter and the Partnership Parties for all reasonable out-of-pocket expenses (including fees and disbursements of counsel) incurred by the Underwriter and the Partnership Parties in connection with this Agreement and the proposed purchase of the Units, and upon demand the Selling Unitholders shall pay the full amount thereof to the Underwriter and the Partnership Parties, as appropriate, or (ii) any failure, refusal or inability on the part of any of the Partnership Parties to perform any agreement on its part to be performed, or because any other condition of the Underwriter’s obligations hereunder required to be fulfilled by the Partnership Parties is not fulfilled for any reason, the Partnership Parties will, jointly and severally, reimburse the Underwriter and the Selling Unitholders for all reasonable out-of-pocket expenses (including fees and disbursements of counsel) incurred by the Underwriter and the Selling Unitholders in connection with this Agreement and the proposed purchase of the Units, and upon demand the Partnership Parties shall pay the full amount thereof to the Underwriter and the Selling Unitholders, as appropriate. If this Agreement is terminated by reason of the default of the Underwriter or pursuant to Section 9(l), neither the Partnership Parties nor the Selling Unitholders shall be obligated to reimburse the Underwriter on account of its expenses.

14. Research Analyst Independence. The Partnership Parties acknowledge that the Underwriter’s research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Underwriter’s research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Partnership and/or the offering that differ from the views of their respective investment banking divisions. The Partnership Parties and the Selling Unitholders hereby waive and release, to the fullest extent permitted by law, any claims that the Partnership Parties or the Selling Unitholders may have against the Underwriter with respect to any conflict of interest that may arise from the fact that the views expressed by its independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Partnership

Parties or the Selling Unitholders by such Underwriter’s investment banking divisions. The Partnership Parties and the Selling Unitholders acknowledge that the Underwriter 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.

15. No Fiduciary Duty. The Partnership Parties and the Selling Unitholders acknowledge and agree that in connection with this offering and sale of the Units or any other services the Underwriter may be deemed to be providing hereunder, notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Underwriter: (i) no fiduciary or agency relationship between the Partnership Parties, the Selling Unitholders and any other person, on the one hand, and the Underwriter, on the other, exists; (ii) the Underwriter is not acting as an advisor, expert or otherwise, to either the Partnership Parties or the Selling Unitholders, including, without limitation, with respect to the determination of the public offering price of the Units, and such relationship between the Partnership Parties and the Selling Unitholders, on the one hand, and the Underwriter, on the other, is entirely and solely commercial, based on arms-length negotiations; (iii) any duties and obligations that the Underwriter may have to the Partnership Parties or the Selling Unitholders shall be limited to those duties and obligations specifically stated herein; and (iv) the Underwriter and its affiliates may have interests that differ from those of the Partnership Parties and the Selling Unitholders. The Partnership Parties and the Selling Unitholders hereby waive any claims that any such entity may have against the Underwriter with respect to any breach of fiduciary duty in connection with this offering.

16. Notices, Etc. All statements, requests, notices and agreements hereunder shall be in writing, and:

Registration No. 333-164253

June 2, 2010

Penn Virginia GP Holdings, L.P.

This free writing prospectus is qualified in its entirety by reference to the Preliminary Prospectus Supplement. The information in this free writing prospectus supplements the Preliminary Prospectus Supplement and supersedes the information in the Preliminary Prospectus Supplement to the extent inconsistent with the information in the Preliminary Prospectus Supplement.

The information under the captions “The U.S. Congress is considering legislation that would cause income earned with respect to certain types of partnership interests to be subject to federal income tax in the same manner as fees received for services and such proposed legislation could apply with respect to allocations of income on and dispositions of our common units and could result in our unitholders being liable for increased taxes” that appears on page S-6 of the Preliminary Prospectus Supplement and “Proposed Carried Interest Legislation” that appears on page S-10 of the Preliminary Prospectus Supplement is replaced in its entirety to read as follows:

The U.S. House of Representatives has passed, and the Senate is considering, legislation that would cause income earned with respect to certain types of partnership interests to be subject to federal income tax as ordinary income (and potentially subject to self-employment taxes to individual service providers). Because of the nature of our ownership interests in Penn Virginia Resource Partners, L.P., the proposed legislation would likely apply with respect to certain allocations of income on and dispositions of our common units and would likely result in our unitholders being liable for increased taxes. Under the proposed legislation, an exception may apply, and therefore the new legislation may not apply, with respect to certain dispositions of partnership interests. Based on a recently published interpretation by the Joint Committee on Taxation of the U.S. Congress, however, we have been advised that this exception would not apply generally to dispositions of our common units. In summary, in the event the legislation were passed in its current form, our common unitholders would recognize ordinary taxable income (rather than capital gain) with respect to a substantial portion of the income allocated on our common units and, under the Joint Committee’s interpretation, with respect to a substantial portion of the income they recognize on disposition of our common units. We are unable to predict whether any of these changes or the exception for certain dispositions will ultimately be enacted or apply to our common unitholders. Any such changes could negatively impact the value of an investment in our common units.

Other information presented in the Preliminary Prospectus Supplement is deemed to have changed to the extent affected by the information contained herein.

(r) The opinion of Vinson & Elkins L.L.P. that is filed as Exhibit 8.1 to the Registration Statement is confirmed and the Underwriter may rely upon such opinion as if it were addressed to them.

To the knowledge of such counsel, no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or threatened by the Commission; and any required filing of the Prospectus pursuant to Rule 424(b) has been made in the manner and within the time period required by such Rule.

A-1-4

(t) The Registration Statement, on the Effective Date and on the Delivery Date, and the Prospectus, when filed with the Commission pursuant to Rule 424(b) and on the Delivery Date, appeared, on their face, appropriately responsive, in all material respects, to the requirements of the Securities Act and the Rules and Regulations, except that in each case such counsel need express no opinion with respect to the financial statements or other financial, accounting, statistical and reserve data contained in or omitted from the Registration Statement or the Prospectus.

(u) The Partnership is not an “investment company” as such term is defined in the Investment Company Act of 1940, as amended.

In rendering such opinion, such counsel may (A) rely in respect of matters of fact upon the representations of the Partnership Parties and the Selling Unitholders set forth in this Agreement and upon certificates of officers and employees of the Partnership Entities and upon information obtained from public officials, (B) assume that all documents submitted to them as originals are authentic, that all copies submitted to them conform to the originals thereof, and that the signatures on all documents examined by them are genuine, (C) state that their opinion is limited to federal laws, the Delaware LP Act, the Delaware LLC Act and the DGCL, (D) with respect to the opinions expressed in subparagraphs (a) through (b) above as to the valid existence, good standing, due qualification or registration as a foreign limited partnership or limited liability company, as the case may be, of the Partnership, PVR, the General Partner or PVR GP, state that such counsel relied solely on certificates of foreign qualification or registration provided by the Secretary of State of the states listed on Annex I (each of which will be dated not more than fourteen days prior to the Delivery Date and shall be provided to you), (E) with respect to the opinions expressed in clause (i) of paragraphs (c), (d), (f) and (g) through (i) above, respectively, such counsel relied solely on reports, dated as of recent dates, purporting to describe all financing statements on file as of the dates specified therein in the office of the Secretary of the State of Delaware naming the Partnership, the General Partner or PVR GP or one of more or them, as debtors, and (F) state that they express no opinion with respect to (i) any permits to own or operate any real or personal property or (ii) state or local taxes or tax statutes to which any of the limited partners of the Partnership or any Partnership Entity may be subject.

In addition, such counsel shall state that they have participated in conferences with officers and other representatives of the Partnership Parties and the independent public accountants of the Partnership and your representatives, at which the contents of the Registration Statement, the Pricing Disclosure Package and the Prospectus and related matters were discussed, and although such counsel has not independently verified, is not passing upon, and is not assuming any responsibility for the accuracy, completeness or fairness of the statements contained in, the Registration Statement, the Pricing Disclosure Package and the Prospectus (except to the extent specified in the foregoing opinion), based on the foregoing, no facts have come to such counsel’s attention that lead such counsel to believe that

(A) the Registration Statement, as of the latest Effective Date, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading,

A-1-5

(B) the Pricing Disclosure Package, as of the Applicable Time, contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, or

A-2-1

charges or encumbrances, in the case of clauses (B), (C) or (D) would materially impair the ability of such Selling Unitholder to perform its obligations under the Underwriting Agreement; provided, however, that for purposes of this paragraph, we express no opinion with respect to federal or state securities laws or any antifraud laws.

(f) No permit, consent, approval, authorization, order, registration, filing or qualification (“consent”) under the Delaware LP Act, the Delaware LLC Act, the DGCL or federal law is required in connection with the execution, delivery and performance of the Underwriting Agreement by the Selling Unitholders or the consummation of the transactions contemplated by the Underwriting Agreement by the Selling Unitholders, except for (i) such consents required under state securities or “Blue Sky” laws, as to which we express no opinion and (ii) such consents that have been obtained.

(the “Selling Unitholders”) of common units representing limited partner interests (the “Common Units”) in Penn Virginia GP Holdings, L.P., a Delaware limited partnership (the “Partnership”), and that the Underwriter proposes to reoffer such Common Units to the public (the “Offering”).

In consideration of the execution of the Underwriting Agreement by the Underwriter, and for other good and valuable consideration, the undersigned hereby irrevocably agrees that, without the prior written consent of Barclays Capital Inc., the undersigned will not, directly or indirectly, (1) offer for sale, sell, pledge, or otherwise dispose of (or enter into any transaction or device that is designed to, or could be expected to, result in the disposition by any person at any time in the future of) any Common Units (including, without limitation, Common Units that may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission and Common Units that may be issued upon exercise of any options or warrants) or securities convertible into or exercisable or exchangeable for Common Units, (2) enter into any swap or other derivatives transaction that transfers to another, in whole or in part, any of the economic benefits or risks of ownership of Common Units, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Units or other securities, in cash or otherwise, (3) make any demand for or exercise any right or cause to be filed a registration statement, including any amendments thereto, with respect to the registration of any Common Units or securities convertible into or exercisable or exchangeable for Common Units or any other securities of the Partnership or (4) publicly disclose the intention to do any of the foregoing, for a period commencing on the date hereof and ending on the 60th day after the date of the Prospectus relating to the Offering (such 60-day period, the “Lock-Up Period”).

Notwithstanding the foregoing, if (1) during the last 17 days of the Lock-Up Period, the Partnership or PVR issues an earnings release or material news or a material event relating to the Partnership or PVR occurs or (2) prior to the expiration of the Lock-Up Period, the Partnership or PVR announces that it will release earnings results during the 16-day period beginning on the last day of the Lock-Up Period, then the restrictions imposed by this Lock-Up Letter Agreement shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the announcement of the material news or the occurrence of the material event, unless the Underwriter waives such extension in writing. The undersigned hereby further agrees that, prior to engaging in any transaction or taking any other action that is subject to the terms of this Lock-Up Letter Agreement during the period from the date of this Lock-Up Letter Agreement to and including the 34th day following the expiration of the Lock-

C-1

Up Period, it will give notice thereof to the Partnership and will not consummate such transaction or take any such action unless it has received written confirmation from the Partnership that the Lock-Up Period (as such may have been extended pursuant to this paragraph) has expired.

In furtherance of the foregoing, the Partnership and its transfer agent are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Lock-Up Letter Agreement.

It is understood that, if the Partnership and the Selling Unitholders notify the Underwriter that they do not intend to proceed with the Offering, if the Underwriting Agreement does not become effective, or if the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Common Units to be included in the Offering, the undersigned will be released from all obligations under this Lock-Up Letter Agreement.

The undersigned understands that the Partnership, the Selling Unitholders and the Underwriter will proceed with the Offering in reliance on this Lock-Up Letter Agreement.

Whether or not the Offering actually occurs depends on a number of factors, including market conditions. Any Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation among the Partnership, the Selling Unitholders and the Underwriter.
