      Section 1.7 Pre-Effective Time Interests and Assets . Immediately prior to the Closing, Purchaser and Seller are the owners of certain working interests relating to lands subject to the Original Lease and the Exploration Agreement. As part of this Agreement and the transactions contemplated hereby (as well as other transactions between the Parties and their Affiliates), the Parties desire to enter into a new lease agreement in substantially the form attached hereto as Exhibit C (the “New Lease”), effective as of the Closing Date, with Purchaser as the lessor and Seller as the lessee, and to terminate the Original Lease, the Exploration Agreement and certain related agreements, effective as of the Closing Date. In addition to the working interests in the Leases and Review Wells and the related assets that Purchaser is purchasing from Seller under this Agreement (as such working interests are more particularly described in the column titled “Conveyed Working Interest” on Exhibit A-2 and the corresponding undivided interests in the Combined Assets associated therewith, the “Assets”). For purposes of clarification, the Parties acknowledge that each Party may currently own some of the interests that will be conveyed or cross conveyed under the Conveyance and that the Conveyance is intended to stipulate and clarify as of the Closing the interests that each of the Parties will own as of the Closing. In order to reflect Purchaser’s pre-Effective Time working interests in the Wells drilled under the Original Lease and/or the Exploration Agreement, Seller, as the lessee under the New Lease, will enter into such conveyances (including the Conveyance) with Purchaser to confirm the pre-Effective Time working interests of Purchaser in such Wells and related assets that will be subject to the New Lease (as such pre-Effective Time working interests are more particularly described in the column titled “Purchaser Pre-Effective Time Working Interest” on Exhibit A-2 and the corresponding undivided interests included in the Combined Assets associated therewith, the “Pre-Effective Time Interests”). The Parties acknowledge that the Assets and the Pre-Effective Time Interests together constitute the Combined Assets and the term “Assets” as defined in this Agreement shall be the Combined Assets excluding the Pre-Effective Time

Interests, and upon Closing, Purchaser and all Purchaser Successors shall collectively hold the interest in each Review Well identified on Exhibit A-2 as the “Purchaser Closing Interest” for such Review Well and the same interest in the Proration Unit for such Review Well, and Seller shall hold the interest in each Review Well identified on Exhibit A-2 as the “Seller Closing Interest” for such Review Well and the same interest in the Proration Unit for such Review Well. Further, the parties acknowledge that certain existing wells drilled by PMOG or its predecessors upon the lands covered by the Original Lease were excluded under the Original Lease and are being excluded under the New Lease (as more particularly described therein), and such excluded wells shall not be part of the Combined Assets, Assets or Pre-Effective Time Interests.

      Section 1.8 Intentions of the Parties . The Parties acknowledge that it is their intent that (a) Seller transfer to Purchaser and Purchaser accept as of the Effective Time an undivided one-half (1/2) of Seller’s interest existing as of the Closing Date in all leases (including without limitation Seller’s interest as lessee under the EPC Lease, but for the avoidance of doubt, excluding its interest as lessor thereunder) included in Buchanan, Russell and Dickenson Counties, Virginia (excluding any interests in the lands and properties excluded from the AMI) and (b) pursuant to the Conveyance, Purchaser shall cross convey to Seller such interest in such leases (but excluding its interest as lessor under the Original Lease or the New Lease), such that the respective interests of the Parties in such leases as lessees thereunder shall be equal as of the Effective Time, whether or not such leases are included in or accurately described on Exhibit A-1. The Parties further acknowledge and agree that it is their intent that, notwithstanding anything herein to the contrary, to the extent that there are any Wells in which both Seller and Purchaser currently have a working interest that exist upon any Leases or within the AMI and that are not described on Exhibit A-2, the respective interests of the Parties in such Wells shall be the same interests as the Parties have in such Wells as of the date hereof; provided, however, if any such Well has been drilled by Seller upon the Leases or within the AMI on or after the Effective Time, then the Parties agree that their respective interests in such Wells and the Proration Units therefor as of the Effective Time shall be equal.

Similarly, the adjustment described in Section 2.2(d) shall serve to satisfy, up to the amount of the adjustment, Purchaser’s obligation under Section 1.5 to pay Property Costs attributable to the ownership and operation of the Assets which are incurred between the Effective Time and the Closing, and Purchaser shall not be separately obligated to pay for any Property Costs with respect to which an adjustment has been made.

Seller and Purchaser agree (a) that the Allocated Values shall be used by Seller and Purchaser as the basis for reporting asset values and other items for purposes of all applicable Tax returns, and (b) that neither they nor their Affiliates will take positions inconsistent with the Allocated Values in notices to Governmental Authorities, in audit or other proceedings with respect to Taxes, in notices to preferential purchaser right holders, or in other documents or notices relating to the transactions contemplated by this Agreement.

     (b) Notwithstanding anything to the contrary in Section 3.1(a) and the Conveyance, Section 3.4 shall provide Purchaser’s exclusive remedy in respect of Asserted Title Defects reported in accordance with this Article 3, and, Purchaser shall not be entitled to make any claims against Seller or any of its Affiliates under Seller’s special warranty of title in the Conveyance against any such Asserted Title Defect. Except to the extent expressly provided herein (including Purchaser’s rights with respect to any breach of Seller’s covenant under Section 6.10(f) and Purchaser’s rights under this Article 3) and except under the special warranty of title set forth in the Conveyance, Purchaser shall not be entitled to make any claims against Seller or any of its Affiliates with respect to any Title Defects to the extent that such Title Defects pertain to the PM Assets (provided that if such Title Defects affect both the PM Assets and the other Assets, then Purchaser shall be entitled to any and all of its rights and remedies with respect to such Title Defects insofar and only insofar as such Title Defects affect such other Assets).

      Section 3.2 Definition of Defensible Title . As used in this Agreement, the term “Defensible Title” means that title of Seller with respect to the Assets which, subject to Permitted Encumbrances:

     (a) entitles Seller to receive throughout the duration of the productive life of any Review Well (after satisfaction of all royalties, overriding royalties, nonparticipating royalties, net profits interests or other similar burdens on or measured by production of Hydrocarbons), not less than the “Conveyed Net Revenue Interest” share shown in Exhibit A-2 for such Review Well of all Hydrocarbons produced and sold from such Review Well, as applicable, except (solely to the extent that such actions do not cause a breach of Seller’s covenants under Section 6.10 hereof) decreases in connection with those operations in which, from or after the date of this Agreement, Seller may be a nonconsenting co-owner, decreases resulting from the establishment or amendment of pools or units from and after the date of this Agreement, and decreases required to allow other working interest owners to make up past underproduction or pipelines to make up past underdeliveries;

     (b) obligates Seller to bear a percentage of the costs and expenses for the maintenance and development of, and operations relating to, a Review Well not greater than the “Conveyed Working Interest” shown in Exhibit A-2 for such Review Well without increase throughout the productive life of such Review Well, as applicable, except as stated in Exhibit A-2, respectively, and except increases resulting from contribution requirements with respect to defaulting co-owners under applicable operating agreements and increases that are accompanied by at least a proportionate increase in Seller’s net revenue interest; and

     (c) is free and clear of all Encumbrances.

     As used in this Agreement, the term “Encumbrance” means any lien, charge, encumbrance, irregularity or other defect (including a discrepancy or error in net revenue interest or working interest as set forth in Exhibit A-2 for a Review Well). The term “Title Defect” means, with respect to any Asset that is a Non-PM Asset, any Encumbrance that would cause

Seller not to have Defensible Title to such Non-PM Asset, and with respect to any Asset that is a PM Asset, the term “Title Defect” means any Encumbrance created by, through or under Seller or any of its Affiliates that would cause Seller not to have Defensible Title to such PM Asset. The term “Asserted Title Defect” means a Title Defect reported by Purchaser pursuant to Section 3.4 hereof.

      Section 3.3 Definition of Permitted Encumbrances . As used herein, the term “Permitted Encumbrances” means any or all of the following:

     (a) lessors’ royalties and any overriding royalties, reversionary interests and other burdens on production of Hydrocarbons to the extent that they do not, individually or in the aggregate, reduce the “Conveyed Net Revenue Interest” below that shown in Exhibit A-2 with respect to any Review Well or increase the “Conveyed Working Interest” above that shown in Exhibit A-2 with respect to any Review Well without at least a proportionate increase in the net revenue interest for such Review Well;

     (b) all Contracts, to the extent that they do not, individually or in the aggregate, reduce the “Conveyed Net Revenue Interest” below that shown in Exhibit A-2 with respect to any Review Well or increase the “Conveyed Working Interest” above that shown in Exhibit A-2 with respect to any Review Well without at least a proportionate increase in the net revenue interest for such Review Well;

     (c) Preferential Rights;

     (d) third-party consent requirements and similar restrictions with respect to which waivers or consents are obtained by Seller from the appropriate parties prior to the Closing Date or the appropriate time period for asserting the right has expired or which are expressly not required to be satisfied prior to a transfer;

     (e) liens for current Taxes or assessments not yet delinquent or, if delinquent, being contested in good faith by appropriate actions and listed on Exhibit A-5;

     (f) materialman’s, mechanic’s, repairman’s, employee’s, contractor’s, operator’s and other similar liens or charges arising in the ordinary course of business for amounts not yet delinquent (including any amounts being withheld as provided by law), or if delinquent, being contested in good faith by appropriate actions and listed on Exhibit A-6;

     (g) all rights to consent, by required notices to, filings with, or other actions by Governmental Authorities in connection with the sale or conveyance of oil and gas leases, licenses, concessions, production sharing agreements or interests therein if they are customarily obtained subsequent to the sale or conveyance;

     (h) rights of reassignment arising upon final intention to abandon or release the Leases included in the Proration Unit for such Review Well;

     (i) easements, rights-of-way, servitudes, permits and other rights in respect of surface and subsurface operations not involving the extraction of Hydrocarbons to the extent that they do not, individually or in the aggregate (i) reduce the “Conveyed Net Revenue Interest” below that shown in Exhibit A-2 with respect to any Review Well, (ii) increase the “Conveyed Working Interest” above that shown in Exhibit A-2 with respect to any Review Well without at least a proportionate increase in the “Conveyed Net Revenue Interest” for such Review Well, or (iii) materially detract from the value of, or materially interfere with the use, ownership or operation of, any Review Well subject thereto or affected thereby (as currently used, owned and operated) and which would be accepted by a reasonably prudent purchaser engaged in the business of owning and operating oil and gas properties in the Appalachian Basin;

     (j) calls on production under existing Contracts that are listed on Exhibit A-7;

     (k) all rights reserved to or vested in any Governmental Authority to control or regulate any of the Wells or Undeveloped Lease Interests in any manner and all obligations and duties under all applicable Laws or under any franchise, grant, license or permit issued by any such Governmental Authority;

     (l) any Encumbrance which is discharged by Seller at or prior to Closing;

     (m) any rights related to coal, coal seams or coal mining, whether statutory or otherwise, other than rights to explore for, develop and produce coalbed methane and associated Hydrocarbons and rights attendant thereto;

      Section 3.4 Notice of Asserted Title Defects; Defect Adjustments .

     (a) To assert a claim of a Title Defect prior to Closing, Purchaser must deliver a claim notice to Seller on or before 5:00 p.m. EDT on April 25, 2007 (the “Title Claim Date”), except as otherwise provided under Section 3.5 or Section 3.6; provided that Purchaser agrees to furnish Seller at the end of every week period following the execution of this Agreement and prior to the Title Claim Date with a claim notice if any officer of Purchaser or its Affiliates discovers or learns of any Title Defect during such period. Each such notice shall be in writing and shall include (i) a description of the Asserted Title Defect(s), (ii) the Wells and/or Undeveloped Lease Interests affected,

(iii) the Allocated Values of the Wells and/or Undeveloped Lease Interests subject to such Asserted Title Defect(s), (iv) supporting documents reasonably necessary for Seller (as well as any title attorney or examiner hired by Seller) to verify the existence of such Asserted Title Defect(s) and (v) the amount by which Purchaser reasonably believes the Allocated Values of those Wells and/or Undeveloped Lease Interests are reduced by such Asserted Title Defect(s) and the computations and information upon which Purchaser’s belief is based. Subject to Purchaser’s rights under the special warranty of title described in Section 3.1(a) and its rights with respect to any breach of Seller’s covenant under Section 6.10(f), Purchaser shall be deemed to have waived all Title Defects of which Seller has not been given notice on or before the Title Claim Date.

     (b) In the event that Purchaser notifies Seller of a Title Defect before the Title Claim Date, Seller shall have the right, but not the obligation, to attempt, at its sole cost, to cure or remove any Asserted Title Defects of which it has been notified by Purchaser. If Seller so elects to cure or remove any Asserted Title Defect, Purchaser shall use commercially reasonable efforts to cooperate with Seller’s efforts to cure or remove such Asserted Title Defect. If prior to Closing, Seller has been unable to cure or remove any Asserted Title Defect, then Seller and Purchaser mutually shall elect to have one of the following options apply:

     (i) Remove the interests in such Well or Undeveloped Lease Interest included in the Assets that is subject to such Asserted Title Defect and those other Assets primarily related to such interest in such Well or Undeveloped Lease Interest from the transaction contemplated by this Agreement. Such removed Assets shall not be assigned at the Closing, shall become “Excluded Assets” for all purposes hereunder and the Purchase Price shall be reduced by an amount equal to the Allocated Value for such Assets, provided that if any Asserted Title Defect is cured at any time prior to one hundred eighty (180) days after Closing, within five (5) days of Seller’s notice to Purchaser of such event, the Parties shall conduct a subsequent Closing (in accordance with the same terms hereof) for the purchase and sale of the Excluded Asset that was subject to such cured Asserted Title Defect.

     (ii) Assign the Asset subject to the Asserted Title Defect to Purchaser at Closing, and defend, indemnify and hold the Purchaser Indemnified Persons and Purchaser Successors harmless from and against all Damages that arise out of or that any such Person may suffer as a result of such Asserted Title Defect pursuant to a form of indemnity agreement mutually agreeable to the Parties.

     (iii) Assign the Asset subject to the Asserted Title Defect to Purchaser at Closing, and reduce the Purchase Price in accordance with Section 3.4(c).

Provided that, if Seller and Purchaser are unable to mutually agree on one of the foregoing options, then the Parties shall be deemed to have chosen the option under subsection (i) above.

     (c) The Purchase Price shall be reduced by an amount (the “Asserted Title Defect Amount”) equal to the reduction in the Allocated Value for the interest in such Well or Undeveloped Lease Interest included in the Assets that is subject to an uncured Asserted Title Defect, which reduction is caused by such uncured Asserted Title Defect as determined pursuant to Section 3.4(e); provided that no reduction shall be made in the Purchase Price with respect to any Asserted Title Defect for which an election has been made pursuant to Section 3.4(b)(ii).

     (d) Except for Purchaser’s rights under the special warranty of title described in Section 3.1(a) and its rights with respect to any breach of Seller’s covenant under Section 6.10(f), Section 3.4(c) shall, to the fullest extent permitted by applicable Laws, be the exclusive right and remedy of Purchaser against Seller or its Affiliates with respect to any Title Defect attributable to the Combined Assets.

     (e) The Asserted Title Defect Amount resulting from an Asserted Title Defect shall be determined as follows:

     (i) if Purchaser and Seller agree on the Asserted Title Defect Amount, that amount shall be the Asserted Title Defect Amount;

     (ii) if the Asserted Title Defect is an Encumbrance which is undisputed and liquidated in amount, then the Asserted Title Defect Amount shall be the amount necessary to be paid to remove the Asserted Title Defect from the affected Well or Undeveloped Lease Interest;

     (iii) if the Asserted Title Defect represents a discrepancy between (A) the actual net revenue interest included in the Assets for any Well or Undeveloped Lease Interest and (B) the “Conveyed Net Revenue Interest” stated on Exhibit A-2 for such Review Well, then the Asserted Title Defect Amount shall be the product of the Allocated Value for the interest in the affected Well or Undeveloped Lease Interest included in the Assets multiplied by a fraction, the numerator of which is the net revenue interest decrease and the denominator of which is the net revenue interest stated on Exhibit A-2 for such interest; provided that if the Asserted Title Defect does not affect a Review Well throughout the life of such Review Well, the Asserted Title Defect Amount determined under this Section 3.4(e)(iii) shall be reduced accordingly;

     (iv) if the Asserted Title Defect represents an Encumbrance of a type not described in subsections (i), (ii) or (iii) above, the Asserted Title Defect Amount shall be determined by taking into account the Allocated Value of the interest in the Review Well included in the Assets so affected, the portion of such interest in the Review Well affected by the Asserted Title Defect, the legal effect of the Asserted Title Defect, the potential economic effect of the Asserted Title Defect over the life of the affected Review Well, the values placed upon the Asserted Title Defect by Purchaser and Seller and such other factors as are necessary to make a proper evaluation; and

     (v) notwithstanding anything to the contrary in this Article 3, (A) except for adjustments required by Section 3.6, the aggregate Asserted Title Defect Amounts attributable to all Asserted Title Defects upon any given interest in a Review Well included in the Assets shall not exceed the Allocated Value of such interest in the Review Well and (B) except for adjustments required by Section 3.5 or Section 3.6, there shall be no Purchase Price adjustment for Asserted Title Defects unless and until the aggregate Asserted Title Defect Amounts for all interests in the Review Wells included in the Assets for which claim notices were timely delivered pursuant to Section 3.4(a) exceed Two Million Six Hundred Twenty Thousand Dollars (US$2,620,000.00), and then only to the extent that the aggregate Asserted Title Defect Amounts exceed Two Million Six Hundred Twenty Thousand Dollars (US$2,620,000.00);

     (vi) if an Asserted Title Defect of the type not described in subsections (i), (ii) or (iii) above is reasonably susceptible of being cured, the Asserted Title Defect Amount determined under subsection (iv) above shall not be greater than the lesser of (1) the reasonable cost and expense of curing such Asserted Title Defect or (2) the share of such curative work cost and expense which is allocated to such interest in such Review Well included in the Assets pursuant to subsection (vii) below; and

     (vii) the Asserted Title Defect Amount with respect to a Review Well shall be determined without duplication of any costs or losses (i) included in another Asserted Title Defect Amount hereunder, or (ii) included in a casualty loss under Section 3.6. To the extent that the cost to cure any Asserted Title Defect will result in the curing of all or a part of one or more other Asserted Title Defects, such cost of cure shall be allocated for purposes of Section 3.4(e)(vi) among the interests in the Review Wells so affected on a fair and reasonable basis.

     (f) Seller and Purchaser shall attempt to agree on all Asserted Title Defects and Asserted Title Defect Amounts by two (2) Business Days prior to the Closing Date. If Seller and Purchaser are unable to agree by that date, the average of Seller’s and Purchaser’s estimates with respect to the Asserted Title Defect Amounts for the Asserted Title Defects shall be used to determine the Closing Payment pursuant to Section 8.4(a), and all Asserted Title Defects and Asserted Title Defect Amounts in dispute shall be exclusively and finally resolved by arbitration pursuant to this Section 3.4(f). During the ten (10) Business Day period following the Closing Date, Asserted Title Defects and Asserted Title Defect Amounts in dispute shall be submitted to an attorney with at least ten (10) years of experience in oil and gas titles in southwestern Virginia as selected by mutual agreement of Purchaser and Seller (the “Title Arbitrator”). The arbitration proceeding shall be held in Pittsburgh, Pennsylvania and shall be conducted in accordance with the Commercial Arbitration Rules of the American Arbitration Association in effect as of the date hereof, to the extent such rules do not conflict with the terms of this Section 3.4(f). The Title Arbitrator’s determination shall be made within twenty (20) days after submission of the matters in dispute and shall be final and binding

upon both Parties, without right of appeal. In making his determination, the Title Arbitrator shall be bound by the rules set forth in Section 3.4(e) and may consider such other matters as in the opinion of the Title Arbitrator are necessary or helpful to make a proper determination. Additionally, with the prior written consent of Purchaser and Seller, the Title Arbitrator may consult with and engage disinterested third parties to advise the Title Arbitrator, including title attorneys from other states and petroleum engineers. In no event shall any Asserted Title Defect Amount exceed the estimate given by Purchaser in its claim notice delivered in accordance with Section 3.4(a). The Title Arbitrator shall act as an expert for the limited purpose of determining the specific disputed Asserted Title Defects and Asserted Title Defect Amounts submitted by either Party and may not award damages, interest or penalties to either Party with respect to any matter. Seller and Purchaser shall each bear its own legal fees and other costs of presenting its case. Each Party shall bear one-half of the costs and expenses of the Title Arbitrator.

      Section 3.5 Consents to Assignment and Preferential Rights to Purchase .

          (a) Seller will use reasonable efforts, consistent with industry practices in transactions of this type, to identify, with respect to all Assets, the names and addresses of all parties holding Preferential Rights and Consents applicable to the transactions contemplated hereby. In attempting to identify the names and addresses of such parties holding such Preferential Rights and Consents, Seller shall in no event be obligated to go beyond its own records. Seller will request, from the parties so identified (and from any parties identified by Purchaser prior to Closing who have Preferential Rights or from whom a Consent may be required), in accordance with the documents creating such rights, execution of waivers of Preferential Rights or Consents so identified. Seller shall have no obligation other than to identify such Preferential Rights and Consents and to so request such execution of waivers of Preferential Rights and Consents (including, without limitation, Seller shall have no obligation to assure that such waivers of Preferential Rights and Consents are obtained).

          (b) With respect to Preferential Rights but not Consents, if a Person from whom a waiver of a Preferential Right is requested refuses to give such waiver prior to Closing, the interest in the Asset subject to such Preferential Right will be excluded from the transaction conte
