TITLE MATTERS

Section 11.1 General Disclaimer of Title Warranties and Representations. Without limiting Buyer’s remedies for Title Defects set forth in this Article XI, Seller makes no warranty or representation, express, implied, statutory or otherwise, with respect to Seller’s title to any of the Assets other than matters arising by, through or under Seller, and Buyer hereby acknowledges and agrees that (except for breaches of any of the covenants of Seller set forth in Section 6.1, for which Buyer will have the remedies provided in Article XII or the special warranty of title in any Conveyance) Buyer’s sole remedy for any defect of title, including any Title Defect, with respect to any of the Assets shall be as set forth in Section 11.2, and that the provisions of Article XII shall not apply with respect to any defect in title, including any Title Defect, to any of the Assets or any breach of any representation, warranty or covenant (other than any covenant set forth in Sections 6.1, 11.2, 11.3 or 14.8) relating to or affecting title, including any Title Defect, to any of the Assets. Notwithstanding anything to the contrary herein, the Parties acknowledge and agree that Buyer shall not be prevented from delivering a Title Defect Notice with respect to any Title Defect caused by or arising from any matter disclosed on Schedule 4.7.

Section 11.2 Notice of Title Defects; Defect Adjustments.

(a) Access for Title Due Diligence. From and after the Execution Date and up to and including the Title Adjustment Claim Date, solely to conduct Buyer’s due diligence investigation of title matters relating to the Assets for purposes of this Article XI, Seller shall afford to Buyer and its officers, employees, agents, accountants, attorneys, investment bankers, landmen, consultants and other representatives of Buyer designated by Buyer (collectively, “Buyer’s Representatives”) reasonable access, during normal business hours, to the Assets and all records and other documents in Seller’s or any of its Affiliates’ possession relating to the title condition of the Assets. Seller shall also make available to Buyer and Buyer’s Representatives, upon reasonable notice during normal business hours, Seller’s and its Affiliates’ personnel knowledgeable with respect to the title condition of the Assets in order that Buyer may make such title diligence investigation as Buyer considers necessary or appropriate. All title due diligence investigations conducted by Buyer or any Buyer’s Representative shall be conducted at Buyer’s sole cost, risk and expense.

(b) Title Claim Notices. On or before the date that is six months following the Closing Date (the “Title Adjustment Claim Date”), (i) Buyer may deliver claim notices to Seller meeting the requirements of this Section 11.2(b) (collectively the “Title Defect Notices,” and each individually a “Title Defect Notice”) setting forth any matters that, in Buyer’s opinion, constitute Title Defects and that Buyer intends to assert as Title Defects pursuant to this Article XI, and (ii) Seller may deliver claim notices to Buyer meeting the requirements of this Section 11.2(b) (collectively the “Title Benefit Notices,” and each individually a “Title Benefit Notice”) setting forth any matters that, in Seller’s opinion, constitute Title Benefits as of the Closing Date and that Seller intends to assert as a Title Benefit pursuant to this Article XI, which Title Benefit Notice must be accompanied by assignment(s) in the form of Exhibit B necessary to convey to Buyer Buyer’s Working Interest Share of any additional Net Acres determined to exist in connection with any Title Benefit to the extent not already covered by any Conveyance already delivered. For all purposes of this Agreement and notwithstanding anything herein to the contrary (except as provided in Section 11.1), Buyer shall be deemed to have waived, and none of Seller or any of the Seller Indemnified Parties shall have any liability for, any Title Defect that Buyer fails to assert as a Title Defect by a Title Defect Notice received by Seller on or before the Title Adjustment Claim Date, and Seller shall be deemed to have waived, and none of Buyer or any of the Buyer Indemnified Parties shall have any liability for, any Title Benefit that Seller fails to assert as a Title Benefit by a Title Benefit Notice received by Buyer on or before the Title Adjustment Claim Date. To be effective, each Title Defect Notice or Title Benefit Notice shall be in writing, and shall include (A) a description of the alleged Title Defect(s) or Title Benefit(s), as applicable, (B) the Subject Properties affected by the Title Defect or Title Benefit, as applicable (each a “Title Adjustment Property”), (C) the Property Designated Value of the Conveyed Interests in each Title Adjustment Property, (D) supporting documents available to the Party giving notice reasonably necessary for the Party receiving notice to verify the existence of the alleged Title Defect(s) or Title Benefit(s), as applicable, and (E) the amount by which the Party giving notice reasonably believes the Property Designated Value of the Conveyed Interests of each Title Adjustment Property is reduced by the alleged Title Defect(s) or increased by the alleged Title Benefit(s), as applicable, and the computations upon which the belief is based. To give the Party receiving notice an opportunity to commence reviewing and curing Title Defects or an opportunity to commence reviewing Title Benefits, the Party giving notice agrees to use reasonable efforts to give the Party receiving notice, on or before the end of each calendar week prior to the Title Adjustment Claim Date, notice (which shall not constitute a Title Defect Notice or Title Benefit Notice) of all Title Defects or all Title Benefits, as applicable, discovered by such Party during the preceding calendar week, which notice shall be preliminary in nature and be supplemented prior to the Title Adjustment Claim Date; provided that failure to provide a preliminary notice of a Title Defect or Title Benefit shall not prejudice the right of Buyer or Seller, as applicable, to assert such Title Defect or Title Benefit in accordance with the terms hereunder. Each of Buyer and Seller shall also promptly furnish the other with written notice of any Title Defect or Title Benefit, as applicable, which is discovered by any of its or any of its Affiliates’ employees, title attorneys, landmen or other title examiners prior to the Title Adjustment Claim Date.

(c) Seller’s Right to Cure. Seller shall have the right, but not the obligation, to attempt, at its sole cost, to cure at any time prior to the date that is six months following its receipt of a Title Defect Notice with respect to a Title Adjustment Property (each such six month period, a “Cure Period”), any Title Defects.

(d) Title Claim Amounts.

(i) If a Title Defect represents a discrepancy between (A) the actual Net Acres for the Title Adjustment Property and (B) the Net Acres for the Title Adjustment Property stated in Exhibit A, then the amount of such Title Defect (the “Title Defect Amount”) shall be the product obtained by multiplying the positive difference of (B) minus (A) by the Property Designated Value for the Title Adjustment Property; provided, however, that if the Title Defect does not affect the Subject Property throughout the entire life of the Subject Lease or interest, then the Title Adjustment Amount determined under this Section 11.2(d)(i) shall be reduced to take into account the applicable time period only.

(ii) Except as provided in Section 11.2(d)(i), the Title Defect Amount shall be the amount by which the Property Designated Value of the Conveyed Interests attributed to the affected Title Adjustment Property is reduced as a result of the existence of the Title Defect and shall be determined in accordance with the following terms and conditions:

(A) if Buyer and Seller agree on the Title Defect Amount, then that amount shall be the Title Defect Amount;

(B) if the Title Defect is an Encumbrance that is undisputed and liquidated in amount, then the Title Defect Amount shall be the amount necessary to be paid to remove the Title Defect from the Title Adjustment Property;

(C) if the Title Defect represents a discrepancy between (1) the actual Net Revenue Interest for the Title Adjustment Property and (2) the Net Revenue Interest for the Title Adjustment Property set forth in Exhibit A, and the Working Interest is not reduced proportionately or reduced by a greater amount, then the Title Defect Amount shall be the product of (x) the Property Designated Value of the Conveyed Interests attributed to the Title Adjustment Property multiplied by (y) a fraction, the numerator of which is the absolute value of the Net Revenue Interest decrease and the denominator of which is the Net Revenue Interest set forth in Exhibit A for the property;

(D) if the Title Defect represents an obligation or Encumbrance upon or other defect in title to the Title Adjustment Property of a type not described above, the Title Defect Amount shall be determined by taking into account the Property Designated Value of the Conveyed Interests attributed to the Title Adjustment Property, the portion of the Title Adjustment Property affected by the Title Defect, the legal effect of the Title Defect, the economic effect of the Title Defect over the life of the Title Adjustment Property, the values placed upon the Title Defect by Buyer and Seller and such other reasonable factors as are necessary to make a proper evaluation; provided, however, that if such Title Defect is reasonably capable of being cured, the Title Defect Amount shall not be greater than the lesser of (1) the reasonable cost and expense of curing such Title Defect and (2) the Property Designated Value of the Conveyed Interests attributable to the Title Adjustment Property;

(iii) The amount of any Title Benefit (“Title Benefit Amount”) shall be determined for Net Acres discrepancies, by multiplying Buyer’s Working Interest Share of the total additional Net Acres actually determined to exist with respect to such Title Benefit by the Property Designated Value; provided, however, that if the Title Benefit does not affect the Subject Property throughout the entire life of the Subject Lease or interest, then the Title Benefit Amount determined under this Section 11.02(d)(iii) shall be increased to take into account the applicable time period only. If the Title Benefit represents a discrepancy between (1) the actual Net Revenue Interest for the Conveyed Interest and (2) the Net Revenue Interest for the Conveyed Interest set forth in Exhibit A, and the Working Interest is not increased proportionally or increased by a greater amount, then the Title Benefit Amount shall be the product of (x) the Property Designated Value of the Conveyed Interest multiplied by (y) a fraction, the numerator of which is the Net Revenue Increase and the denominator of which is the Net Revenue Interest set forth in Exhibit A for the Conveyed Interest.

(iv) The Title Defect Amount or Title Benefit Amount with respect to a Title Adjustment Property shall be determined without duplication of any costs or losses included in another Title Defect Amount or Title Benefit Amount pertaining to the Title Adjustment Property hereunder.

(v) Notwithstanding anything to the contrary, the aggregate Title Defect Amounts attributable to the effects of all Title Defects under this Section 11.2(d) on any Title Adjustment Property shall not exceed the Property Designated Value of the Conveyed Interests attributable to that Title Adjustment Property.

(vi) For purposes of this Section 11.2(d), “Conveyed Interests” shall mean an undivided 50% of Seller’s right, title and interest in the Assets, as determined immediately prior to Closing.

(e) Title Dispute Resolution. Seller and Buyer shall attempt to agree on all Title Defects and Title Defect Amounts prior to the expiration of the applicable Cure Period and each Title Benefit as soon as practicable after delivery of the Title Benefit Notice. If Seller and Buyer have not agreed to any Title Defect and Title Defect Amount and/or Title Benefit and Title Benefit Amount in dispute (a “Title Dispute”), either Party, by notice to the other, may require it to be exclusively and finally resolved pursuant to this Section 11.2(d) (which may be no earlier than the expiration of the applicable Cure Period in the case of a Title Defect or Title Defect Amount or the date that is 30 days after the delivery of the applicable Title Benefit Notice in the case of a Title Benefit or Title Benefit Amount). There shall be a single arbitrator, who shall be a title attorney experienced in oil and gas titles involving properties in the regional area in which the Title Defect Properties or the Subject Property relating to the Title Benefit, as applicable, are located (the “Title Arbitrator”). The Title Arbitrator shall be selected by agreement of Buyer and Seller within 15 days after the delivery of notice of the Title Dispute, and absent such agreement at the request of either Party, by the Houston, Texas office of the AAA. The place of arbitration shall be Houston, Texas and the arbitration shall be conducted in accordance with the AAA Rules, to the extent those rules do not conflict with the terms of this Article XI. In addition to being bound by and adhering to the rules and practices of the AAA and applicable law on arbitrator neutrality, the Title Arbitrator shall not have worked as an employee or outside counsel for either Party or any Affiliate of a Party during the five-year period preceding the arbitration or have any financial interest in the dispute. The Parties shall instruct the Title Arbitrator to make an award within 20 days after the closing of the hearing. The Title Arbitrator’s award 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 Sections 11.2(d) and the AAA Rules. The Title Arbitrator, however, may not award (i) Buyer a greater Title Defect Amount than the Title Defect Amount claimed by Buyer in its applicable Title Defect Notice, or a lower Title Defect Amount than the Title Defect Amount proposed by Seller in its response to such Title Defect Notice and (ii) Seller a greater Title Benefit Amount than the Title Benefit Amount claimed by Seller in its applicable Benefit Notice, or a lower Title Benefit Amount than the Title Benefit Amount proposed by Buyer in its response to such Benefit Notice or its applicable Benefit Notice, as applicable. The Title Arbitrator shall determine the specific disputed Title Defect, Title Defect Amount, Title Benefit and Title Benefit Amount submitted by either Party and may not award damages, interest or penalties to either Party with respect to any other matter. Seller and Buyer shall bear their own legal fees and other costs of presenting their case. Seller and Buyer shall each bear one-half of the costs and expenses of the Title Arbitrator.

(f) Payment for Title Defects and Title Benefits. On or before the fifth Business Day after the latest of (A) the date on which the last applicable Cure Period expires, (B) the date on which the last outstanding Title Defect is cured by Seller or (C) the date on which the last outstanding Title Dispute is resolved:

(i) If the Net Title Adjustment Amount is a positive number in excess of $1,050,000, then Buyer shall pay Seller, by a wire transfer of immediately available funds to an account specified by Seller, an amount equal to that excess, or

(ii) If the Net Title Adjustment Amount is a negative number whose absolute value is in excess of $1,050,000, then Seller shall refund to Buyer, by wire transfer of immediately available funds to an account specified by Buyer, a portion of the Purchase Price equal to that excess or, at Buyer’s election, credit such amount against any amounts owing under any of the Transaction Documents.

“Net Title Adjustment Amount” means the result (which may be a positive or negative amount) of (x) the aggregate of all Title Benefit Amounts, minus (y) the aggregate of all Title Defect Amounts, minus (z) the Property Designated Value of any reduction in, or loss of, any acres included in the Conveyed Interests that results from the transfer, sale, mortgage, pledge, expiration, encumbrance or disposition between the Effective Date and the Closing Date of any portion of the Conveyed Interests in accordance with Section 6.1(c). For the avoidance of doubt, no payment or other adjustment shall be made if the absolute value of the Net Title Adjustment Amount is equal to or less than $1,050,000.

Section 11.3 Casualty or Condemnation Loss. If, after the Execution Date but prior to the Closing Date, (a) any portion of the Conveyed Interests is taken by any Governmental Authority in condemnation or under right of eminent domain, (b) any action for condemnation or taking under right of eminent domain is pending or threatened with respect to any of the Conveyed Interests or portion thereof, but no taking of such Conveyed Interests or portion thereof occurs prior to the Closing Date, or (c) any portion of the Conveyed Interests is materially damaged or destroyed by fire or other casualty, then, in each case, the Conveyed Interests or portion thereof shall be excluded from the Conveyed Interests to be conveyed to Buyer to the extent of the interest affected by the condemnation or eminent domain or material damage or destruction, and the Purchase Price shall be reduced by the Property Designated Value of the relevant Conveyed Interest; provided, however, that Buyer shall have the right, on or before the tenth day after receipt of notice of any event described in clause (a), (b) or (c) of this Section 11.3, to elect, in its sole discretion, to continue to include such portion of the Conveyed Interests in the Conveyed Interests to be conveyed to Buyer, with no reduction in the Purchase Price.

Without limiting Buyer’s rights to indemnity under this Article XII and Buyer’s remedies for Title Defects in Article XI, from and after the Closing, Buyer shall assume and hereby agrees to fulfill, perform, pay and discharge (or cause to be fulfilled, performed, paid or discharged) all obligations and Liabilities, known or unknown, to extent arising from, based upon, related to or associated with the Conveyed Interests, to the extent (and only to the extent) arising after the Effective Time, including such obligations and Liabilities under the Applicable Contracts and plugging and abandonment obligations arising after the Effective Time for wells drilled prior to the Effective Time; provided, however, that Buyer does not assume (and the Assumed Obligations shall not include) any claims for which Seller is required to indemnify Buyer pursuant to this Article XII or pay pursuant to Section 14.2 (the “Assumed Obligations”).

Section 12.2 Indemnities by Seller. Effective as of the Closing, subject to the limitations set forth in Section 12.4 and otherwise in this Article XII, Seller and its successors and assigns shall be responsible for, shall pay, and will defend, indemnify and hold harmless Buyer and its Affiliates, and all of its and their respective equity holders, partners, members (excluding, in each case, equity holders, partners or members solely by virtue of holding publicly traded shares, units or other interests), and directors, officers, managers, employees, agents and representatives (collectively, the “Buyer Indemnified Parties”) from and against any and all Liabilities to the extent arising from, based upon, related to or associated with:

Section 12.3 Indemnities by Buyer. Effective as of the Closing, Buyer and its successors and assigns shall be responsible for, shall pay, and will defend, indemnify, and hold harmless Seller and all of its equity holders, partners, members (excluding, in each case, equity holders, partners or members solely by virtue of holding publicly traded shares, units or other interests), and directors, officers, managers, employees, agents and representatives (collectively, the “Seller Indemnified Parties”) from and against any and all Liabilities to the extent arising from, based upon, related to or associated with:

(a) any breach by Buyer of its representations or warranties contained in Article V;

(b) any breach by Buyer of its covenants and agreements under this Agreement; or

(a) Seller shall not have any liability for indemnification under Section 12.2(a) (except for liability for indemnification for breaches of the representations and warranties in Sections 4.1, 4.2, 4.11 or 4.12) or 12.2(b) (but only with respect to any breach of Section 6.1(g) to the extent that that breach would cause a breach of a representation or warranty subject to this Section 12.4(a)) until and unless the aggregate amount of all Liabilities for which Claim Notices are delivered by Buyer exceeds the Aggregate Deductible, and then only to the extent such damages exceed the Aggregate Deductible.

(b) Notwithstanding anything to the contrary contained in this Agreement, (i) Seller shall not be required to indemnify Buyer under Sections 12.2(a) (except for liability for indemnification for breaches of the representations and warranties in Sections 4.1, 4.2, 4.11 and 4.12) or 12.2(b) for aggregate Liabilities in excess of $10,000,000; and (ii) the sum of the total liability of Seller for any indemnity under Section 12.2(a), 12.2(b) and 12.2(c) and the Net Title Adjustment Amount, if any, for which Seller shall be responsible under Article XI shall not exceed the aggregate of the Purchase Price plus the Drilling Carry Cap plus the amount of PA Payments.

(c) The limitations of this Section 12.4 shall not apply to Seller’s obligation to bear and pay any amounts for which Seller is responsible under Section 14.2.

(d) EXCEPT FOR DAMAGES PAID TO THIRD PERSONS TO WHICH AN INDEMNITY OR CONTRIBUTION OBLIGATION UNDER SECTION 12.2 OR SECTION 12.3 APPLIES, NEITHER PARTY SHALL BE LIABLE TO THE OTHER PARTY FOR EXEMPLARY, PUNITIVE, TREBLE, INDIRECT, OR CONSEQUENTIAL DAMAGES, AND THE PARTIES AND THEIR AFFILIATES WAIVE ANY RIGHT THEY MAY HAVE TO RECOVER SUCH DAMAGES FROM ONE ANOTHER.

(e) For purposes of determining whether there is a breach of any representation, warranty, covenant or agreement for which Buyer is entitled to indemnification under this Agreement and the amount of damages therefrom to which Buyer is entitled under this Agreement, the words “Seller Material Adverse Effect,” “material,” “materially,” and words of similar import in the applicable provisions of this Agreement shall be disregarded.

Section 12.5 Express Negligence. THE INDEMNIFICATION, RELEASE AND ASSUMED OBLIGATIONS PROVISIONS PROVIDED FOR IN THIS AGREEMENT SHALL BE APPLICABLE WHETHER OR NOT THE LIABILITIES, LOSSES, COSTS, EXPENSES AND DAMAGES IN QUESTION AROSE OR RESULTED SOLELY OR IN PART FROM THE SOLE, ACTIVE, PASSIVE, CONCURRENT OR COMPARATIVE NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT OR VIOLATION OF LAW OF OR BY ANY INDEMNIFIED PARTY, BUT NOT THE GROSS NEGLIGENCE, FRAUD OR WILLFUL MISCONDUCT OF ANY INDEMNIFIED PARTY. BUYER AND SELLER ACKNOWLEDGE THAT THIS STATEMENT COMPLIES WITH THE EXPRESS NEGLIGENCE RULE AND IS CONSPICUOUS.

Section 12.6 Exclusive Remedy. Notwithstanding anything to the contrary contained in this Agreement, Sections 11.1, 12.2, 12.3, 13.2 and 13.3 contain the Parties’ exclusive remedy against each other with respect to breaches of the representations, warranties, covenants and agreements of the Parties contained in this Agreement; provided, however, that nothing in this Section 12.6 shall limit Buyer’s remedies for Title Defects in Article XI, and nothing herein shall limit in any way any Party’s remedies in respect of fraud or willful misconduct by the other Party in connection with the transactions contemplated hereby; provided, further, that nothing herein shall limit in any way a Party’s remedies under any other Transaction Document.

Section 12.7 Indemnification Procedures. All claims for indemnification under Sections 12.2 and 12.3 shall be asserted and resolved as follows:

(a) For purposes of this Article XII, the term “Indemnifying Party,” when used in connection with particular Liabilities, shall mean the Party having an obligation to indemnify another Party or Person(s) with respect to such Liabilities pursuant to this Article XII, and the term “Indemnified Party,” when used in connection with particular Liabilities, shall mean the Party or Person(s) having the right to be indemnified with respect to such Liabilities by a Party pursuant to this Article XII.

(b) To make a claim for indemnification under Sections 12.2 or 12.3, an Indemnified Party shall notify the Indemnifying Party of its claim under this Section 12.7, including the specific details of, the facts underlying and the specific basis under this Agreement for its claim (the “Claim Notice”).

(c) If a claim for indemnification is based upon a claim by a Third Party against the Indemnified Party (a “Third Party Claim”), the Indemnified Party shall provide its Claim Notice promptly after the Indemnified Party has actual knowledge of the Third Party Claim and shall enclose a copy of all papers (if any) served with respect to the Third Party Claim; provided, however, that the failure of any Indemnified Party to give notice of a Third Party Claim as provided in this Section 12.7 shall not relieve the Indemnifying Party of its obligations under Sections 12.2 or 12.3 except to the extent such failure results in insufficient time being available to permit the Indemnifying Party to effectively defend against the Third Party Claim or otherwise materially prejudices the Indemnifying Party’s ability to defend against the Third Party Claim. In the event that a claim for indemnification is based upon an inaccuracy or breach of a representation, warranty, covenant or agreement, the Claim Notice shall specify the representation, warranty, covenant or agreement that was inaccurate or breached.

(d) In the case of a Third Party Claim, the Indemnifying Party shall notify the Indemnified Party whether it shall assume the defense of such Third Party Claim. The Indemnified Party is authorized, prior to notice by the Indemnifying Party that it shall assume the defense of such Third Party Claim, at the expense of the Indemnifying Party, to file any motion, answer or other pleading that it shall deem necessary or appropriate to protect its interests or those of the Indemnifying Party and that is not prejudicial to the Indemnifying Party.

(e) If the Indemnifying Party shall have assumed the defense of the Third Party Claim, the Indemnifying Party shall have full control of such defense and proceedings, including any compromise or settlement thereof. If requested by the Indemnifying Party, the Indemnified Party shall cooperate in contesting any Third Party Claim that the Indemnifying Party elects to contest. The Indemnified Party may participate in, at its own expense, but not control, any defense or settlement of any Third Party Claim controlled by the Indemnifying Party pursuant to this Section 12.7. An Indemnifying Party shall not, without the written consent of the Indemnified Party, (i) settle any Third Party Claim or consent to the entry of any judgment with respect thereto that does not include an unconditional release of the Indemnified Party from all liability in respect of such Third Party Claim or (ii) settle any Third Party Claim or consent to the entry of any judgment with respect thereto in any manner that may materially and adversely affect the Indemnified Party (other than as a result of money damages covered by the indemnity set forth in this Article XII).

(f) If the Indemnifying Party does not assume the defense of the Third Party Claim, then the Indemnified Party shall have the right to defend against the Third Party Claim at the sole cost and expense of the Indemnifying Party, with counsel reasonably satisfactory to the Indemnifying Party. Any settlement of the Third Party Claim shall require the consent of the Indemnifying Party, unless the settlement is solely for money damages and results in a final resolution, and an unconditional written release, of the Indemnified Party’s Liability with respect to such claim.

Section 12.8 Survival.

(a) The representations and warranties of the Parties in Articles IV and V (other than, (i) the representations and warranties in Sections 4.11, 4.12, 4.13, and 5.9, which shall survive for the applicable statute of limitations, (ii) the representations and warranties in Sections 4.1, 4.2, 5.1, and 5.2, which shall survive indefinitely, and (iii) the representations and warranties in Section 5.7, which shall not survive the Closing), shall survive for 18 months after the Closing Date. Representations and warranties shall be of no further force and effect after the date of their expiration; provided, however, that there shall be no termination of any bona fide Third Party Claim (or claim) asserted pursuant to this Agreement with respect to such a representation and warranty prior to its expiration date.

(b) The indemnities in Sections 12.2(a) and 12.3(a) shall terminate as of the termination date of each respective representation and warranty that is subject to indemnification; provided, however, that such termination shall not terminate or otherwise affect any Third Party Claim (or other claim) properly asserted pursuant to Article XII prior to the date of such termination (in the case of a representation and warranty) or any Third Party Claim (or other claim) properly asserted pursuant to Article XII with respect to breaches of any representations or warranties occurring prior to the date of such termination. The indemnities in Sections 12.2(b) and 12.3(b) with respect to each covenant or agreement shall survive until such covenant or agreement has been fully performed and the statute of limitations applicable to any breach thereof has expired. Buyer’s indemnities in Section 12.3(c) shall survive the Closing without time limit. Seller’s indemnities set forth in Sections 12.2(c) and 12.2(d) shall survive the Closing without time limit.

Section 12.9 Waiver of Right to Rescission. Subject to Sections 13.2 and 13.3, the Parties acknowledge that the payment of money, as limited by the terms of this Agreement, shall be adequate compensation for breach of any representation, warranty, covenant or agreement contained herein or for any other claim arising in connection with or with respect to the transactions contemplated in this Agreement. Subject to Sections 13.2 and 13.3, as the payment of money shall be adequate compensation, Buyer and Seller waive any right to rescind this Agreement or any of the transactions contemplated hereby.

Section 12.10 Insurance; Taxes. The amount of any Liabilities for which an Indemnified Party is entitled to indemnification under this Agreement shall be reduced by any corresponding net tax benefit or insurance proceeds realized by such Indemnified Party or its Affiliates from third party insurers with respect to such Liabilities (net of any collection costs, and excluding the proceeds of any insurance underwritten by the Indemnified Party or its Affiliates).

Section 12.11 Disclaimer of Application of Anti-Indemnity Statutes. The Parties acknowledge and agree that the provisions of any anti-indemnity statute relating to oilfield services and associated activities shall not be applicable to this Agreement and/or the transactions contemplated hereby.

(a) written consent of both Parties;

(b) by either Party, in writing delivered to the other Party after 60 days after the Execution Date (the “Termination Date”), if the Closing has not occurred by such date; provided that the right to terminate this Agreement under this Section 13.1(b) shall not be available to a Party that has breached in any material respect any of its obligations under this Agreement and that breach has been the cause of, or resulted in, the failure of the satisfaction of a condition to the Closing to occur on or before the Termination Date;

(c) by either Party, in writing delivered to the other Party, without prejudice to other rights and remedies that the terminating Party may have, if the other Party (i) has materially failed to perform its covenants or agreements contained herein required to be performed on or prior to the Closing Date, or (ii) has materially breached any of its representations or warranties contained herein, in each of cases (i) and (ii), such that the conditions set forth in Sections 7.1, 7.2, 8.1 or 8.2, as applicable, are not satisfied on or before the Termination Date or are incapable of being satisfied;

(d) by either Party, in writing delivered to the other Party, without liability, if there shall be any order, writ, injunction or decree of any Governmental Authority binding on any of the Parties that prohibits or restrains the Parties from consummating the Closing; provided that such Party shall have used its reasonable best efforts to have any such order, writ, injunction or decree lifted and the same shall not have been lifted within 30 days after entry by any such Governmental Authority;

(e) by Buyer, in writing delivered to Seller, if any of the conditions set forth in Article VII have become incapable of fulfillment prior to the Termination Date, and have not been waived in writing by Buyer; or

(f) by Seller, in writing delivered to Buyer, if any of the conditions set forth in Article VIII have become incapable of fulfillment prior to the Termination Date, and have not been waived in writing by Seller.

Section 13.2 Failure to Close and Remedies. Without prejudice to other rights and remedies that may be available to the non-breaching Party, the Parties agree that, in the event Closing does not occur by the Termination Date as a result of the breach by a Party of any of its covenants or agreements in this Agreement in any material respect prior to the Closing, the other Party shall be entitled, at its option, in lieu of terminating this Agreement, to enforce specific performance and other equitable remedies by way of injunction. Each Party agrees to waive any requirement for the posting of a bond in connection with any such equitable relief in favor of the other Party.

Section 13.3 Effects of Termination. If the obligation to close the transactions contemplated by this Agreement is terminated pursuant to any provision of Section 13.1, then, except for the provisions of Sections 1.1, 1.2, 10.1, 13.3, 13.4, 14.2(a), 14.6, 14.7, 14.10, 14.11, 14.12 and 14.14, this Agreement shall forthwith become void and the Parties shall have no liability or obligation hereunder except and to the extent such termination results from the material breach by a Party of any of its covenants or agreements hereunder prior to the Closing; provided, however, that, except as stated above, in the case of material breach by either Party of any of its covenants or agreements hereunder prior to the Closing, the other Party shall be entitled to all remedies available at Law or in equity and shall be entitled to recover court costs and attorneys’ fees in addition to any other relief to which such Party may be entitled.

Section 13.4 Return of Documentation and Confidentiality. Upon termination of this Agreement, the Confidentiality Agreement shall govern the return, destruction and confidentiality of all title, engineering, geological and geophysical data, environmental assessments and/or reports, maps and other information furnished by or on behalf of Seller to Buyer or prepared by or on behalf of Buyer in connection with its due diligence investigation of the Conveyed Interests.

ARTICLE XIV

MISCELLANEOUS

Section 14.1 Exhibits and Schedules. All of the Exhibits and Schedules referred to in this Agreement are hereby incorporated into this Agreement by reference and constitute a part of this Agreement. Each Party and its counsel has received a complete set of Exhibits and Schedules prior to and as of the Closing Date.

Section 14.2 Expenses and Taxes.

(a) Except as otherwise specifically provided, all fees, costs and expenses incurred by Buyer or Seller in negotiating this Agreement or in consummating the transactions contemplated by this Agreement shall be paid by the Party incurring the same, including legal and accounting fees, costs and expenses.

(b) All required documentary, filing and recording fees and expenses in connection with the filing and recording of the assignments (including the Conveyances), conveyances or other instruments required to convey title to the Conveyed Interests to Buyer shall be borne by both Parties in equal shares. Seller shall assume responsibility for, and shall bear and pay, all federal income taxes, state income taxes, and other similar taxes (including any applicable interest or penalties) incurred or imposed on Seller with respect to the ownership of the Assets through the Closing Date and the transactions described in this Agreement. All state, county and local sales and use taxes and transfer and similar taxes (including any applicable interest or penalties) (the “Transfer Taxes”) incurred or imposed with respect to the transactions contemplated in Section 2.1 shall be borne equally by Seller and Buyer. Seller shall assume responsibility for, and shall bear and pay, all Asset Taxes assessed with respect to the ownership and operation of the Conveyed Interests for (i) any period ending prior to the Effective Time and (ii) any Straddle Period multiplied by a fraction, the numerator of which is the number of days in the Straddle Period ending immediately prior to the Effective Time and the denominator of which is the number of days in the entire Straddle Period. All Asset Taxes with respect to the ownership or operation of the Conveyed Interests arising on or after the Effective Time (including all Straddle Period Taxes not apportioned to Seller) shall be allocated to and borne by Buyer. Upon determination of the actual amount of Asset Taxes, Seller shall promptly pay to Buyer any additional amount necessary to equal Seller’s share of the Asset Taxes. In the event the amount of Asset Taxes paid by Seller exceeds Seller’s share of Asset Taxes, Buyer promptly shall pay the amount of any such excess to Seller.

(c) Seller shall timely file any return with respect to Asset Taxes due on or before the Closing or that otherwise relates solely to periods before the Closing (a “Pre-Closing Asset Tax Return”) and shall pay any Asset Taxes shown due and owing on such Pre-Closing Asset Tax Return, subject to Seller’s right of reimbursement for any Asset Taxes for which Buyer is responsible under Section 14.2(b). Not less than fifteen (15) days prior to filing, Seller shall deliver to Buyer a draft of any such Pre-Closing Asset Tax Return for Buyer’s review and approval (which approval will not be unreasonably withheld or delayed).

Section 14.3 Allocation of Consideration for Tax Purposes. Seller and Buyer agree that the portion of the Purchase Price, as adjusted, and the Assumed Obligations treated for federal tax purposes as consideration for a sale transaction (collectively, the “Allocable Amount”) shall be allocated among the various Conveyed Interests for federal and state income tax purposes. The initial draft of such allocations shall be prepared by Seller in a manner consistent with Schedule 14.3 and shall be provided to Buyer no later than the date occurring four months after the Closing. Seller and Buyer shall then cooperate to prepare a final schedule of the Allocable Amount among the Conveyed Interests, which shall also be materially consistent with Schedule 14.3 (as adjusted, the “Allocation Schedule”). The Allocation Schedule shall be updated to reflect any adjustments to the Allocable Amount. The allocation of the Allocable Amount shall be reflected on a completed Internal Revenue Service Form 8594 (Asset Acquisition Statement under Section 1060), which Form will be timely filed separately by Seller and Buyer (and/or the Tax Partnership, as appropriate) with the Internal Revenue Service pursuant to the requirements of Section 1060(b) of the Code. Each Party agrees not to (and to cause the Tax Partnership not to) take any position inconsistent with the allocations set forth in the Allocation Schedule unless required by applicable Law or with the consent of the other Party. The Parties further agree that the allocations set forth on the Allocation Schedule will represent reasonable estimates of the fair market values of the Conveyed Interests described therein.

Section 14.4 Assignment. This Agreement may not be assigned by either Party, in whole or in part, without the prior written consent of the other Party.

Section 14.5 Preparation of Agreement. Both Seller and Buyer and their respective counsel participated in the preparation of this Agreement. In the event of any ambiguity in this Agreement, no presumption shall arise based on the identity of the draftsman of this Agreement.

Section 14.6 Publicity. Neither of the Parties nor their Affiliates shall issue any press release or similar public announcement pertaining to this Agreement, the other Transaction Documents or the transactions contemplated hereby or thereby without the prior consent of the other Party (which consent shall not be unreasonably withheld, delayed or conditioned), except as may be required by applicable Law or by obligations pursuant to any listing agreement with any national securities exchange, as reasonably determined by the Party issuing such press release or making such public announcement, in which case such issuing or announcing Party shall provide prior notice of such press release or public announcement to the other Party; provided, however, that, in the case of any press release or public announcement to be issued or made in connection with Closing, the Parties agree to reasonably cooperate in advance of such issuance or announcement.

Section 14.10 Entire Agreement; Conflicts; Confidentiality Agreement.

(a) THIS AGREEMENT, THE EXHIBITS AND SCHEDULES HERETO, THE OTHER TRANSACTION DOCUMENTS AND, SUBJECT TO SECTION 14.10(b), THE CONFIDENTIALITY AGREEMENT, COLLECTIVELY CONSTITUTE THE ENTIRE AGREEMENT AMONG SELLER AND BUYER PERTAINING TO THE SUBJECT MATTER HEREOF AND SUPERSEDE ALL PRIOR AGREEMENTS, UNDERSTANDINGS, NEGOTIATIONS, AND DISCUSSIONS, WHETHER ORAL OR WRITTEN, OF THE PARTIES PERTAINING TO THE SUBJECT MATTER HEREOF (SPECIFICALLY INCLUDING THE LETTER DATED JULY 27, 2010 AMONG ATINUM PARTNERS CO., LTD., FINE PARTNERS CORP. AND GASTAR EXPLORATION LTD., RELATING TO EXCLUSIVITY). THERE ARE NO WARRANTIES, REPRESENTATIONS, OR OTHER AGREEMENTS AMONG THE PARTIES RELATING TO THE SUBJECT MATTER HEREOF EXCEPT AS SPECIFICALLY SET FORTH IN THIS AGREEMENT OR THE OTHER TRANSACTION DOCUMENTS, AND NEITHER SELLER NOR BUYER SHALL BE BOUND BY OR LIABLE FOR ANY ALLEGED REPRESENTATION, PROMISE, INDUCEMENT, OR STATEMENT OF INTENTION NOT SO SET FORTH. IN THE EVENT OF A CONFLICT BETWEEN THE TERMS AND PROVISIONS OF THIS AGREEMENT AND THE TERMS AND PROVISIONS OF ANY EXHIBIT HERETO, THE TERMS AND PROVISIONS OF THIS AGREEMENT SHALL GOVERN AND CONTROL; PROVIDED, HOWEVER, THAT THE INCLUSION IN ANY OF THE EXHIBITS HERETO OF TERMS AND PROVISIONS NOT ADDRESSED IN THIS AGREEMENT SHALL NOT BE DEEMED A CONFLICT, AND ALL SUCH ADDITIONAL PROVISIONS SHALL BE GIVEN FULL FORCE AND EFFECT, SUBJECT TO THE PROVISIONS OF THIS SECTION 14.10(a).

(b) Prior to Closing, the Parties agree that the Confidentiality Agreement shall remain in effect following the Execution Date and any termination of this Agreement in accordance with Article XIII.

Section 14.11 Parties in Interest. The terms and provisions of this Agreement shall be binding upon and inure to the benefit of Seller and Buyer and their respective legal representatives, successors, and permitted assigns. No other Person shall have any right, benefit, priority, or interest hereunder or as a result hereof or have standing to require satisfaction of the provisions hereof in accordance with their terms.

Section 14.12 Amendment. This Agreement may be amended only by an instrument in writing executed by the Parties hereto against whom enforcement is sought.

Section 14.13 Waiver; Rights Cumulative. Any of the terms, covenants, representations, warranties, or conditions hereof may be waived only by a written instrument executed by or on behalf of the Party waiving compliance. No course of dealing on the part of Seller or Buyer, or their respective officers, employees, agents, or representatives, nor any failure by Seller or Buyer to exercise any of its rights under this Agreement shall operate as a waiver thereof or affect in any way the right of such Party at a later time to enforce the performance of such provision. No waiver by a Party of any condition, or any breach of any term, covenant, representation, or warranty contained in this Agreement, in any one or more instances, shall be deemed to be or construed as a further or continuing waiver of any such condition or breach or a waiver of any other condition or of any breach of any other term, covenant, representation, or warranty. The rights of Seller and Buyer under this Agreement shall be cumulative, and the exercise or partial exercise of any such right shall not preclude the exercise of any other right.

Section 14.14 Governing Law; Dispute Resolution.

(a) THIS AGREEMENT AND THE LEGAL RELATIONS BETWEEN THE PARTIES SHALL BE GOVERNED BY AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH THE LAWS OF TEXAS (EXCEPT THAT, WITH RESPECT TO ISSUES RELATING TO TITLE TO REAL PROPERTY LOCATED IN (I) PENNSYLVANIA, THE LAWS OF THE COMMONWEALTH OF PENNSYLVANIA SHALL GOVERN, (II) WEST VIRGINIA, THE LAWS OF THE STATE OF WEST VIRGINIA SHALL GOVERN, (III) NEW YORK, THE LAWS OF THE STATE OF NEW YORK SHALL GOVERN AND (IV) OHIO, THE LAWS OF THE STATE OF OHIO SHALL GOVERN), EXCLUDING ANY CONFLICTS OF LAW RULE OR PRINCIPLE THAT MIGHT REFER TO THE LAWS OF ANOTHER JURISDICTION.

(b) ANY DISPUTE, CONTROVERSY OR CLAIM, DIRECTLY OR INDIRECTLY, ARISING OUT OF OR RELATING TO THIS AGREEMENT, ANY ANCILLARY AGREEMENT OR THE TRANSACTIONS THEY CONTEMPLATE, OR THE VALIDITY, INTERPRETATION, CONSTRUCTION, PERFORMANCE, BREACH, TERMINATION OR ENFORCEABILITY OF THIS AGREEMENT OR ANY ANCILLARY AGREEMENT, WHETHER SOUNDING IN CONTRACT, TORT, STATUTE, COMMON LAW, OR EQUITY (A “DISPUTE”) SHALL BE FINALLY, EXCLUSIVELY AND CONCLUSIVELY RESOLVED BY BINDING ARBITRATION UNDER THE RULES OF ARBITRATION OF THE INTERNATIONAL CHAMBER OF COMMERCE (THE “ICC”) THEN IN EFFECT (THE “ICC RULES”), EXCEPT AS MODIFIED IN THIS AGREEMENT. THE AGREEMENT TO ARBITRATE AS SET OUT IN THIS SECTION 14.14 SHALL BE BINDING ON AND SHALL INURE TO THE BENEFIT OF THE PARTIES AND THEIR AFFILIATES.

(c) The arbitral tribunal shall be comprised of three arbitrators. The claimant shall nominate one arbitrator and the respondent shall nominate one arbitrator in accordance with the ICC Rules, and the two arbitrators so nominated shall nominate a third arbitrator, who shall chair the arbitral tribunal within 30 days of the confirmation by the ICC Court of Arbitration (the “ICC Court”) of the appointment of the second arbitrator. If the chair or any other arbitrator is not timely appointed, on the request of either Party the chair or the other arbitrator shall be appointed by the ICC Court. Any chair appointed by the ICC Court shall be an experienced arbitrator, with at least 15 years’ experience as a judge or practicing attorney, and shall be unaffiliated and without prior or current financial alliances with any party. If practicable, the chair shall also have experience relating to transactions involving the acquisition, development and operation of oil and gas leases.

(d) The arbitration proceedings shall be conducted in the English language, and all documents not in English submitted by either Party as evidence must be accompanied by a certified English translation. The arbitration proceedings shall be conducted and any arbitral award shall be rendered in Houston, Texas.

(e) Any claim that involves a Dispute relating to rights or obligations that are also the subject of a dispute arising under or relating to another agreement involving one or more of the Parties may be joined in a single arbitration by the claimant, and any arbitration under this Agreement that involves a dispute relating to rights or obligations that are also at issue in another arbitration proceeding under another agreement involving one or both of the Parties shall, at the request of either Party, be consolidated with that other arbitration proceeding, with the consolidated proceeding to be conducted as a single arbitration before the panel of arbitrators appointed or nominated in connection with the earliest-initiated arbitration of the arbitrations to be consolidated; provided, that the arbitral panel for the arbitration so selected determines that: (i) the later Dispute presents significant issues of law or fact in common with those in the prior pending arbitration, (ii) neither Party to the dispute would be unduly prejudiced and (iii) such consolidation would not result in undue delay for the prior pending arbitration. The Parties agree that, upon such an order of consolidation, they will promptly discontinue any arbitration, the subject of which has been consolidated into another arbitral proceeding in connection with this Agreement.

(f) Each Party shall have the right to request the other Party to produce certain specified documents or categories of documents directly relevant to the issues in dispute. In making any determination regarding the scope of production, the arbitral tribunal shall be guided by the International Bar Association Rules on the Taking of Evidence in International Commercial Arbitration.

(g) The arbitration hearing on the merits shall begin no later than six months after the appointment of the arbitrators is completed, unless the arbitrators determine, upon good cause shown, that the commencement of the hearing should be deferred until up to nine months after the appointment of the arbitrators is completed. The award shall be rendered no later than 30 days after the hearing on the merits is concluded.

(h) In rendering an award, the arbitral tribunal shall be required to follow the law of the jurisdiction designated by the Parties herein, provided that issues involving application of arbitration law shall be governed by the Federal Arbitration Act, 9 U.S.C. §§ 1 et. seq. The artibtral tribunal shall not be empowered to award any damages limited by Section 12.4(d). In addition to direct damages, subject to Section 12.6, the arbitral tribunal may award temporary or permanent injunctive relief, and any other relief available at law or in equity, including but not limited to specific performance of any obligation under this Agreement or any ancillary agreement. The arbitral tribunal shall award costs, attorneys’ fees, and expert witness fees to the prevailing Party. The award shall include interest, at the Specified Rate (or, if such rate is contrary to any applicable usury Law, the maximum rate permitted by such applicable Law), from the date of any default, breach, or other accrual of a claim until the arbitral award is paid in full. The award shall be final and binding upon the Parties subject only to grounds and procedures for vacating or modifying the award under the Federal Arbitration Act, 9 U.S.C. §§ 1 et. seq. The award shall be the sole and exclusive remedy between the Parties regarding any claims, counterclaims, issues or accounting presented to the arbitral tribunal. Judgment upon any award may be entered in any court having jurisdiction thereof, over a Party or any of its assets. The Parties and their Affiliates agree to jointly request that any application for recognition or enforcement of an award be decided by the court on an expedited basis. All Parties and their Affiliates waive their right to appeal any court order confirming, recognizing, or enforcing the award. The Parties and their Affiliates do not waive any rights they may have to appeal a court order refusing to confirm, recognize, or enforce an award.

(i) By agreeing to arbitration, the Parties do not intend to deprive any court sitting in Houston, Texas of its jurisdiction to issue a pre-arbitral injunction, pre-arbitral attachment, or other order in aid of arbitration proceedings and the enforcement of any award. The Parties and their Affiliates agree that no court other than a court sitting either in Houston, Texas will have authority or jurisdiction to enter interim orders, including but not limited to temporary restraining orders or temporary injunctive relief, and the Parties and their Affiliates shall not make any application for interim orders to any court other than a court sitting in Houston, Texas. Without prejudice to such provisional remedies as may be available under the jurisdiction of a court sitting in Houston, Texas, the arbitral tribunal shall have full authority to grant provisional remedies and to direct the parties to the arbitration to request that any court modify or vacate any temporary or preliminary relief issued by that court, and to award damages for the failure of any party to respect the arbitral tribunal’s orders to that effect.

(j) All notices by one party to a Dispute to another in connection with the arbitration shall be in accordance with the provisions of Section 14.7. Additionally, Buyer has appointed CT Corporation System, 350 N. St. Paul St. Ste 2900, Dallas, TX 75201, as its agent for service of process in connection with any Dispute or in connection with any application for an interim order from a court sitting in Houston, Texas. Buyer shall maintain the appointment and designation described in this Section 14.14(j) for service of process in Texas until the earlier of (a) one year following the expiration or termination of this Agreement and (b) the expiration or termination of the Participation Agreement; provided that such one year period shall be tolled in the event that this Agreement terminates as a result of any material breach by Buyer. The Parties agree that service of process in any court proceeding of the type described in Section 14.14(h) or Section 14.14(i) shall be effective if sent by certified mail to the Party to be served in the manner provided for the giving of notices in Section 14.7.

(k) The arbitration conducted pursuant hereto shall be confidential. No party to a Dispute shall disclose or permit the disclosure of any information about the evidence adduced or the documents produced by another party to the Dispute in the arbitration proceedings or about the existence, contents or results of the proceeding, except as may be required by a Governmental Authority or by law or a regulatory authority or as required in an action in aid of arbitration or for enforcement of an arbitral award. Before making any disclosure permitted by the preceding sentence, the party to the Dispute intending to make the disclosure shall notify the other parties to the Dispute of the intended disclosure and afford them a reasonable opportunity to protect their interests.

Section 14.15 Severability. If any term or other provision of this Agreement is invalid, illegal, or incapable of being enforced by any rule of Law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any adverse manner to either Party. Upon such determination that any term or other provision is invalid, illegal, or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the extent possible.

Section 14.16 Multiple Counterparts. This Agreement may be executed in any number of counterparts, all of which together shall constitute one agreement binding on the Parties. A facsimile or email transmission of a scanned, executed counterpart of this Agreement shall be sufficient to bind a Party to the same extent as an original.
