Other than as disclosed in the 2004 Annual Report, no significant changes were made in the Partnership’s internal controls over financial reporting since December 31, 2004 that have materially affected the Partnership’s internal control over financial reporting.

2. Representations, Warranties and Agreements of the Selling Unitholder. The Peabody Parties represent and warrant to, and agree with, the Penn Virginia Parties and the Underwriters that:

(a) Formation, Due Qualification of Peabody Energy. Peabody Energy is a corporation duly formed and validly existing in good standing under the laws of the State of Delaware with full corporate power and authority to own and lease its properties and to conduct its business, in each case in all material respects.

(b) Formation, Due Qualification of the Selling Unitholder. The Selling Unitholder is a general partnership duly formed and validly existing in good standing under the laws of the State of Delaware with full partnership power and authority to own and lease its properties and to conduct its business, in each case in all material respects.

(c) Ownership of Selling Unitholder. Peabody Energy indirectly, through one or more direct or indirect wholly owned subsidiaries, owns all of the outstanding partnership interests of the Selling Unitholder; such partnership interests have been duly authorized and validly issued in accordance with the partnership agreement of the Selling Unitholder and are fully paid and nonassessable; such partnership interests are owned free and clear of all liens, encumbrances, security interests, equities, charges or claims.

(d) No Conflicts. None of the execution, delivery and performance of this Agreement by the Peabody Parties or the consummation of the transactions contemplated hereby (i) constitutes or will constitute a violation of the organizational documents of any of the Peabody Parties, (ii) constitutes or will constitute a breach or violation of, or a default (or an event which, with notice or lapse of time or both, would constitute such a default) under, any indenture, mortgage, deed of trust, loan agreement, lease or other agreement or instrument to which any of the Peabody Parties is a party or by which any of them or any of their respective properties may be bound, (iii) violates or will violate any statute, law or regulation or any order, judgment, decree or injunction of any court or governmental agency or body directed to any of the Peabody Parties or any of their properties in a proceeding to which any of them or their property is or was a party, or (iv) results or will result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of any of the Peabody Parties, which

conflicts, breaches, violations, defaults or liens, in the case of clauses (ii), (iii) or (iv), would, individually or in the aggregate, have a material adverse effect on the condition (financial or otherwise), business, prospects, assets or results of operations of the Peabody Parties, taken as a whole.

(e) Title to Units. The Selling Unitholder has good and valid title to the Peabody Units, free and clear of all liens, encumbrances, security interests, equities or claims; and upon delivery of such Peabody Units and payment therefor pursuant hereto, good and valid title to such Peabody Units, free and clear of all liens, encumbrances, security interests, equities or claims, will pass to the Underwriters. Assuming that the Underwriters do not have notice of any adverse claim (as defined in Sections 8-102 and 8-105 of the New York Uniform Commercial Code) to the Peabody Units, upon the delivery to the Underwriters of certificates evidencing the Peabody Units registered in the name of the Underwriters (or their nominees) and payment by the Underwriters of the purchase price for the Peabody Units, the Underwriters (or such nominees) will each be a “protected purchaser” (as such term is used in Section 8-303 of the New York Uniform Commercial Code).

(f) Authorization of Agreement. This Agreement has been duly authorized, executed and delivered by the Peabody Parties, and the Selling Unitholder has all requisite power, authority and capacity to sell and deliver the Peabody Units in accordance with and upon the terms and conditions set forth in this Agreement, the Resale Registration Statement and the Prospectus. At the First Delivery Date, all action required to be taken by the Peabody Parties or, if applicable, their stockholders or partners, for the sale and delivery of the Peabody Units and the consummation of the transactions contemplated by this Agreement shall have been validly taken.

(g) No Material Misstatements or Omissions. Although the Peabody Parties have not independently verified and are not passing upon and assume no responsibility for the accuracy, completeness or fairness of the statements contained in the Resale Registration Statement and Prospectus (except for the information in the Prospectus under the caption “Selling Unitholder”), the Peabody Parties have no reason to believe that the Resale Registration Statement, as of the Resale Effective Time, contained an untrue statement of material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or that the Prospectus contains an untrue statement of a material fact or omits to state a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; provided that no representation or warranty is made as to information contained in or omitted from the Registration Statements or the Prospectus in reliance upon and in conformity with written information furnished to the Partnership by or on behalf of the Underwriters specifically for inclusion therein.

(h) Stabilization. The Peabody Parties have not taken and will not take, directly or indirectly, any action which is designed to or which has constituted or which might reasonably be expected to cause or result in the stabilization or manipulation of the price of any security of the Partnership to facilitate the sale or resale of the Units.

(i) No Consents. No consent of or with any court, governmental agency or body having jurisdiction over the Peabody Parties or any of their respective properties is required

in connection with the execution, delivery and performance of this Agreement, or the consummation by the Peabody Parties of the transactions contemplated by this Agreement, except for such consents required under the Securities Act, Exchange Act and state securities or “Blue Sky” laws.

On the basis of the representations and warranties contained in, and subject to the terms and conditions of, this Agreement, the Partnership agrees to sell the Partnership Units, and the Selling Unitholder agrees to sell the Peabody Units, to the Underwriters, and the Underwriters agree to purchase such Firm Units.

In addition, the Partnership grants to the Underwriters an option to purchase up to 502,500 Option Units. Such option is granted for the purpose of covering over-allotments in the sale of Firm Units and is exercisable as provided in Section 5 hereof. Option Units shall be purchased severally for the account of the Underwriters in proportion to the number of Firm Units set forth opposite the respective names of such Underwriters in Schedule I hereto. The respective purchase obligations of each Underwriter with respect to the Option Units shall be adjusted by the Underwriters so that no Underwriter shall be obligated to purchase Option Units other than in 100 unit amounts.

The price of both the Firm Units and any Option Units shall be $50.01 per Unit. The Partnership and the Selling Unitholder shall not be obligated to deliver any of the Units to be delivered on the First Delivery Date or the Second Delivery Date (as hereinafter defined), as the case may be, except upon payment for all the Units to be purchased on such Delivery Date as provided herein.

4. Offering of Units by the Underwriters. Upon authorization by the Underwriters of the release of the Firm Units, the Underwriters propose to offer the Firm Units for sale upon the terms and conditions set forth in the Prospectus.

This date and time are sometimes referred to as the “First Delivery Date.” On the First Delivery Date, the Partnership and the Selling Unitholder shall deliver or cause to be delivered certificates representing the Firm Units to the Underwriters for the account of the Underwriters against payment to or upon the order of the Partnership and the Selling Unitholder of the purchase price by wire transfer in immediately available funds. Time shall be of the essence, and delivery at the time and place specified pursuant to this Agreement is a further condition of the obligation of each Underwriter hereunder.

The option granted in Section 3 will expire 30 days after the date of this Agreement and may be exercised in whole or in part from time to time by written notice being given to the Partnership by the Underwriters. Such notice shall set forth the aggregate number of Option Units as to which the option is being exercised, the names in which the Option Units are to be registered, the denominations in which the Option Units are to be purchased and the date

and time, as determined by the Underwriters, when the Option Units are to be delivered; provided, however, that this date and time shall not be earlier than the First Delivery Date nor earlier than the second business day after the date on which the option shall have been exercised nor later than the fifth business day after the date on which the option shall have been exercised. The date and time the Option Units are delivered are sometimes referred to as the “Second Delivery Date,” and the First Delivery Date and the Second Delivery Date are sometimes each referred to as a “Delivery Date.”

Delivery of and payment for the Option Units shall be made at the place specified in the first sentence of the first paragraph of this Section 5 (or at such other place as shall be determined by agreement between the Underwriters and the Partnership) at 10:00 A.M., New York City time, on the Second Delivery Date. On the Second Delivery Date, the Partnership shall deliver or cause to be delivered certificates representing the Option Units to the Underwriters for the account of the Underwriters against payment to or upon the order of the Partnership of the purchase price by wire transfer in immediately available funds. Time shall be of the essence, and delivery at the time and place specified pursuant to this Agreement is a further condition of the obligation of each Underwriter hereunder.

giving rise to such loss, claim, damage, liability, action or expense. The foregoing indemnity agreement is in addition to any liability which the Penn Virginia Parties may otherwise have to the Underwriters or to any officer, employee or controlling person of the Underwriters.

(b) The Peabody Parties, jointly and severally, shall indemnify and hold harmless each Underwriter and the Penn Virginia Parties, their officers and employees, and each person, if any, who controls any Underwriter or the Penn Virginia Parties within the meaning 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 such Underwriter, the Penn Virginia Parties, their officers, employees or any 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 Statements or the Prospectus or in any amendment or supplement thereto, (ii) the omission or alleged omission to state in the Registration Statements, or in any amendments or supplements thereto, any material fact required to be stated therein or necessary to make the statements therein not misleading, (iii) the omission or alleged omission to state in any Preliminary Prospectus, the Prospectus or in any amendment or supplement thereto, any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, and shall reimburse each Underwriter, the Penn Virginia Parties, their officers and employees and each such controlling person for any legal or other expenses reasonably incurred by such Underwriter, the Penn Virginia Parties, their officers and employees or any 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, in each case to the extent, and only to the extent, that such untrue statement or omission or alleged untrue statement or omission relates to information under the caption “Selling Unitholder” or was made in reliance upon or in conformity with written information furnished to the Partnership by the Peabody Parties specifically for inclusion therein, it being understood and agreed that the only such written information furnished by the Peabody Parties appears in the Prospectus under the caption “Selling Unitholder”; provided, however, that the Peabody 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 or the Prospectus or in any such amendment or supplement in reliance upon and in conformity with written information concerning the Underwriters furnished to the Partnership by or on behalf of the Underwriters specifically for inclusion therein which information consists solely of the information specified in Section 10(f); provided, further, that with respect to the Preliminary Prospectus, the foregoing indemnity in this Section 10(b) shall not inure to the benefit of any Underwriter from whom the person asserting any loss, claim, damage, liability or expense purchased Units, or any of its directors, officers or employees or any person controlling such Underwriter, if copies of the Prospectus were timely delivered to the Underwriters and a copy of the Prospectus (as then amended or supplemented if the Partnership shall have furnished any amendments or supplements thereto) was not sent or given by or on behalf of the Underwriters to such person, if required by law so to have delivered, at or prior to the written confirmation of the sale of the Units to such person, and if the Prospectus (as so amended or supplemented) would have cured the defect giving rise to such loss, claim, damage, liability, action or expense. The foregoing indemnity agreement is in addition to any liability

which the Peabody Parties may otherwise have to the Underwriters or any of the Penn Virginia Parties or any officer, employee or controlling person of the Underwriters or any of the Penn Virginia Parties.

(c) Each Underwriter, severally and not jointly, shall indemnify and hold harmless the Penn Virginia Parties, their officers and employees, each of their directors, and each person, if any, who controls the Penn Virginia Parties within the meaning 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 Penn Virginia Parties or any such director, officer 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 Statements or the Prospectus or in any amendment or supplement thereto, or (ii) the omission or alleged omission to state in the Registration Statements, 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 (iii) the omission or alleged omission to state in any Preliminary Prospectus, the Prospectus or in any amendment or supplement thereto, any material fact necessary to make the statements therein, in light of the circumstances under which there 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 Underwriters furnished to the Penn Virginia Parties by or on behalf of the Underwriters specifically for inclusion therein which information consists solely of the information specified in Section 10(f), and shall reimburse the Penn Virginia Parties and any such director, officer or controlling person for any legal or other expenses reasonably incurred by the Penn Virginia Parties or any such director, officer 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. The foregoing indemnity agreement is in addition to any liability which the Underwriters may otherwise have to the Penn Virginia Parties or any such director, 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 ▇▇▇▇▇▇ Brothers Inc. and RBC Capital Markets

Corporation, as representatives of the several underwriters, shall have the right to employ counsel to represent jointly the Underwriters and their respective officers, employees and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the Underwriters against the Partnership or the Peabody Parties under this Section 10 if, in the reasonable judgment of ▇▇▇▇▇▇ Brothers Inc. and RBC Capital Markets Corporation, as representatives of the several underwriters, it is advisable for the Underwriters, officers, employees and controlling persons to be jointly represented by separate counsel, and in that event the fees and expenses of one such separate counsel (plus one local counsel if necessary in the opinion of counsel to the indemnified party) shall be paid by the Partnership or the Peabody Parties. 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, 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 of 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 Partnership and the Peabody Parties, on the one hand, and the Underwriters, on the other hand, 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 Penn Virginia Parties and the Peabody Parties, on the one hand, and the Underwriters, on the other hand, with respect to the statements or omissions which 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 Partnership and the Peabody Parties on the one hand and the Underwriters 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 Partnership and the Peabody Parties, on the one hand, and the total underwriting discounts and commissions received by the Underwriters with respect to the Units purchased under this Agreement, on the other hand, bear to the total gross proceeds from the offering of the Units under this Agreement, in each case as set forth in the table on the cover page of the Prospectus. 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 Penn Virginia Parties, the Peabody Parties or the Underwriters, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or

omission. The Penn Virginia Parties, the Peabody Parties and the Underwriters 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 (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which 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), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Units underwritten by it and distributed to the public was offered to the public exceeds the amount of any damages which such 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. The Underwriters’ obligations to contribute as provided in this Section 10(e) are several in proportion to their respective underwriting obligations and not joint.

(f) The Underwriters severally confirm and the Penn Virginia Parties acknowledge that the statements with respect to the public offering of the Units by the Underwriters set forth on the cover page of the Prospectus and the concession and reallowance figures in the fourth paragraph and the statements in the ninth, tenth, eleventh, fourteenth, fifteenth, seventeenth, eighteenth and nineteenth paragraphs appearing under the caption “Underwriting” in the Prospectus are correct and constitute the only information concerning the Underwriters furnished in writing to the Partnership by or on behalf of the Underwriters specifically for inclusion in the Registration Statements and the Prospectus.

11. Defaulting Underwriters. If, on any Delivery Date, any Underwriter defaults in the performance of its obligations under this Agreement, the remaining non-defaulting Underwriters shall be obligated to purchase the Units which the defaulting Underwriter agreed but failed to purchase on such Delivery Date in the respective proportions which the number of Firm Units set opposite the name of each remaining non-defaulting Underwriter in Schedule I hereto bears to the total number of Units set opposite the names of all the remaining non-defaulting Underwriters in Schedule I hereto; provided, however, that the remaining non-defaulting Underwriters shall not be obligated to purchase any of the Units on such Delivery Date if the total number of Units which the defaulting Underwriter or Underwriters agreed but failed to purchase on such date exceeds 9.09% of the total number of Units to be purchased on such Delivery Date, and any remaining non-defaulting Underwriter shall not be obligated to purchase more than 110% of the number of Units which it agreed to purchase on such Delivery Date pursuant to the terms of Section 3. If the foregoing maximums are exceeded, the remaining non-defaulting Underwriters, or those other underwriters satisfactory to ▇▇▇▇▇▇ Brothers Inc. who so agree, shall have the right, but shall not be obligated, to purchase, in such proportion as may be agreed upon among them, all the Units to be purchased on such Delivery Date. If the remaining Underwriters or other underwriters satisfactory to ▇▇▇▇▇▇ Brothers Inc. do not elect to purchase the Units which the defaulting Underwriter or Underwriters agreed but failed to purchase on such Delivery Date, then this Agreement shall terminate without liability on the part

of any non-defaulting Underwriter or any of the Penn Virginia Parties or Peabody Parties, except that the Partnership and the Selling Unitholder will continue to be liable for the payment of expenses to the extent set forth in Sections 8 and 13. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context requires otherwise, any party not listed in Schedule I hereto who, pursuant to this Section 11, purchases Units which a defaulting Underwriter agreed but failed to purchase.

Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Penn Virginia Parties or the Peabody Parties, including expenses paid pursuant to Section 8 and 13, for damages caused by its default. If other underwriters are obligated or agree to purchase the Units of a defaulting or withdrawing Underwriter, either ▇▇▇▇▇▇ Brothers Inc. or the Partnership may postpone the Delivery Date for up to seven full business days in order to effect any changes that in the opinion of counsel for the Partnership or counsel for the Underwriters may be necessary in the Registration Statements, the Prospectus or in any other document or arrangement.

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

13. Reimbursement of Underwriters’ Expenses. If the Selling Unitholder shall fail to tender the Peabody Units for delivery to the Underwriters by reason of any failure, refusal or inability on the part of any Peabody Party to perform any agreement on its part to be performed, or because any other condition of the Underwriters’ obligations hereunder required to be fulfilled by the Peabody Parties is not fulfilled, the Peabody Parties, jointly and severally, will reimburse the Underwriters and the Penn Virginia Parties for all reasonable out of pocket expenses (including fees and disbursements of counsel) incurred by the Underwriters and the Penn Virginia Parties in connection with this Agreement and the proposed purchase of the Units, and upon demand the Peabody Parties shall pay the full amount thereof to the Underwriters and the Penn Virginia Parties, as appropriate. If the Partnership shall fail to tender the Partnership Units for delivery to the Underwriters by reason of any failure, refusal or inability on the part of any member of the Penn Virginia Parties to perform any agreement on its part to be performed, or because any other condition of the Underwriters’ obligations hereunder required to be fulfilled by the Penn Virginia Parties is not fulfilled, the Penn Virginia Parties will, jointly and severally, reimburse the Underwriters and the Peabody Parties for all reasonable out-of-pocket expenses (including fees and disbursements of counsel) incurred by the Underwriters and the Peabody Parties in connection with this Agreement and the proposed purchase of the Units, and upon demand the Penn Virginia Parties shall pay the full amount thereof to the Underwriters and the Peabody Parties, as appropriate. If this Agreement is terminated pursuant to Section 11 by reason of the default of one or more Underwriters or pursuant to Section 9(l), neither the Peabody Parties nor the Penn Virginia Parties shall be obligated to reimburse the Underwriters on account of their expenses.

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

(a) if to any of the Penn Virginia Parties, shall be delivered or sent by mail, telex or facsimile transmission to such Penn Virginia Party at ▇▇▇ ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇ ▇▇▇, ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇, Attention: ▇▇. ▇▇▇▇▇ ▇. ▇▇▇▇▇▇, General Counsel (Fax: 610/▇▇▇-▇▇▇▇);

(c) if to the Peabody Parties, shall be delivered or sent by mail or telecopy transmission to Peabody Energy Corporation, ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇. ▇▇▇▇▇, ▇▇▇▇▇▇▇▇ ▇▇▇▇▇-▇▇▇▇, Attention ▇▇. ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇, Esquire, Vice President, General Counsel and Secretary (telecopier no. 314-342-3419).

Any such statements, requests, notices or agreements shall take effect at the time of receipt thereof. The Partnership and the Peabody Parties shall be entitled to act and rely upon any request, consent, notice or agreement given or made on behalf of the Underwriters and the Underwriters shall be entitled to act and rely upon any request, consent, notice or agreement given or made on behalf of the Peabody Parties or the Partnership.

15. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the Underwriters, the Peabody Parties, the Penn Virginia Parties and their respective successors. This Agreement and the terms and provisions hereof are for the sole benefit of only those persons, except that (A) the representations, warranties, indemnities and agreements of the Peabody Parties and the Penn Virginia Parties contained in this Agreement shall also be deemed to be for the benefit of the person or persons, if any, who control the Underwriters within the meaning of Section 15 of the Securities Act, (B) the indemnity agreement of the Peabody Parties contained in Section 10(b) of this Agreement shall be deemed to be for the benefit of directors of the General Partner, officers of the General Partner who have signed the Registration Statements and any person controlling any of the Penn Virginia Parties within the meaning of Section 15 of the Securities Act, and (C) the indemnity agreement of the Underwriters contained in Section 10(c) of this Agreement shall be deemed to be for the benefit of directors of the General Partner, officers of the General Partner who have signed the Registration Statements and any person controlling any of the Penn Virginia Parties within the meaning of Section 15 of the Securities Act. Nothing in this Agreement is intended or shall be construed to give any person, other than the persons referred to in this Section 15, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein.

16. Survival. The respective indemnities, representations, warranties and agreements of the Penn Virginia Parties, the Peabody Parties and the Underwriters contained in

this Agreement or made by or on behalf on them, respectively, pursuant to this Agreement, shall survive the delivery of and payment for the Units and shall remain in full force and effect, regardless of any investigation made by or on behalf of any of them or any person controlling any of them.

17. Definition of the Terms “Business Day” and “Subsidiary”. For purposes of this Agreement, (a) “business day” means any day on which the New York Stock Exchange is open for trading, and (b) “subsidiary” has the meaning set forth in Rule 405 of the Rules and Regulations.

18. Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

19. Counterparts. This Agreement may be executed in one or more counterparts and, if executed in more than one counterpart, the executed counterparts shall each be deemed to be an original but all such counterparts shall together constitute one and the same instrument.

20. Headings. The headings herein are inserted for convenience of reference only and are not intended to be part of, or to affect the meaning or interpretation of, this Agreement.

In addition, such counsel shall state that they have participated in conferences with officers and other representatives of the Penn Virginia Parties and the independent public accountants of the Partnership and your representatives at which the contents of the Registration Statements and the Prospectus and related matters were discussed, and although such counsel has not independently verified, is not passing on, and is not assuming any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statements 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 the Registration Statements (other than (i) the financial statements included therein or incorporated by reference, including the notes and schedules thereto and the auditors’ reports thereon, (ii) the other financial, statistical and accounting data included therein or incorporated by reference and (iii) the reserve information included therein or incorporated by reference, as to which such counsel need not comment), at the time the Partnership’s Annual Report on Form 10-K for the year ended December 31, 2004 was filed with the Commission, 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, or that the Prospectus (other than (i) the financial statements included therein or incorporated by reference, including the notes and schedules thereto and the auditors’ reports thereon, (ii) the other financial, statistical and accounting data included therein or incorporated by reference and (iii) the reserve information included therein or incorporated by reference, as to which such counsel need not comment), as of its issue date and as of each Delivery Date, contained or contains an 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.

Ladies and Gentlemen:

The undersigned understands that you propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) among Penn Virginia Resource Partners, L.P. (the “Partnership”), Penn Virginia Resource GP, LLC, Penn Virginia Operating Co., LLC, Peabody Natural Resources Company (the “Selling Unitholder”), Peabody Energy Corporation (“Peabody Energy”) and ▇▇▇▇▇▇ Brothers Inc., RBC Capital Markets Corporation, UBS Securities LLC, ▇.▇. ▇▇▇▇▇▇▇ & Sons, Inc., Friedman, Billings, ▇▇▇▇▇▇ & Co., Inc. and ▇▇▇▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇ Inc., as Underwriters (the “Underwriters”), providing for the purchase by you from the Partnership and/or the Selling Unitholder of common units representing limited partner interests (the “Common Units”) in the Partnership, and that the Underwriters propose to reoffer the Common Units to the public (the “Offering”). Capitalized terms used but not defined herein have the meanings given to them in the Underwriting Agreement.

In consideration of the execution of the Underwriting Agreement by the Underwriters, and for other good and valuable consideration, the undersigned hereby irrevocably agrees that, without the prior written consent of ▇▇▇▇▇▇ Brothers Inc. and RBC Capital Markets Corporation, the undersigned will not, directly or indirectly, (1) offer for sale, sell, pledge or otherwise dispose of (or enter into any transaction or device which 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 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 option or warrant) or securities convertible into or exchangeable for Common Units owned by the undersigned on the date of execution of this Lock-up Letter Agreement or on the date of the completion of the Offering, or (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 such 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, for a period of 90 days from the date of the Prospectus (as defined in the Underwriting Agreement).

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.

D-1

It is understood that, if the Selling Unitholder or the Partnership notifies you 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, we will be released from our obligations under this Lock-Up Letter Agreement.

The undersigned understands that the Partnership, the Selling Unitholder and the Underwriters 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 between the Partnership, the Selling Unitholder and the Underwriters.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Lock-Up Letter Agreement and that, upon request, the undersigned will execute any additional documents necessary in connection with the enforcement hereof. Any obligations of the undersigned shall be binding upon the [heirs, personal representatives,] [Note: use this language for lock-ups signed by natural persons] [successors and assigns] [Note: use this language for lock-ups signed by Penn Virginia affiliate companies] of the undersigned.

Yours very truly,
